Abstract

PROBLEM TO BE SOLVED: To contrive the compatibility of washing capability capable of wide range washing and the miniaturization of a device. SOLUTION: A bidet movable body NH1-11 opposes the magnetic action parts NH1-18a to 18c of the lower end to the electromagnetic coils NH1-33a to 33c of the inside of a nozzle head in a head swing state on the nozzle head. The movable body is inclined by attracting the magnetic action part to an excitation coil. The inclination of the movable body is generated by shifting along the coil excitation forward direction by the successive excitation of each electromagnetic coil. Thus, a bidet water discharge hole NH1-10 is inclined at a water discharge swing angle α together with the movable body, and swinging and rotation are performed accompanying the inclination position shift of the movable body as it remains the inclined posture. Thereby water discharge from the water discharge hole takes water discharge shape so that a pattern water discharge water column RT is conical, and the water discharge direction is three-dimensionally deflected together with the swinging and rotation of the movable body. In this case, the excitation frequency of the coil is made a dead zone frequency (5 Hz or more) making an intermittent stimulus of a repeating stimulus and impossible to detect.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a human body washing apparatus for washing a human body by discharging supplied washing water.

[0002]

2. Description of the Related Art Conventionally, a human body washing apparatus of this type, particularly a local washing apparatus which is mounted on a toilet to wash a local part of a human body, has a purpose of cleaning a wider area, a purpose of changing a portion to be cleaned, and a method of cleaning a human body. In the case, for the purpose of changing the cleaning feeling, the cleaning water discharged from the cleaning nozzle draws a predetermined trajectory,
Cleaning water is being spouted. Various techniques have been proposed for discharging the washing water so as to draw a predetermined trajectory.

[0003] JP-A-8-284236 and JP-A-9-6
In 0088, the cleaning nozzle itself is moved along a predetermined trajectory by combining the movement of the cleaning nozzle itself in the front-rear direction and the movement in the left-right direction, and the cleaning water is discharged.

Japanese Patent Application Laid-Open No. Sho 61-53929 discloses a method of combining cleaning fluid with a fluid element mechanism for deflecting the direction of spouting of cleaning water and movement of the cleaning nozzle itself in a direction different from the direction of deflection by the fluid element mechanism. Is discharged while moving along a predetermined locus.

[0005] Here, the spouting that deflects the spouting direction of the washing water two-dimensionally means the spatial spread of spouting water that is produced by deflecting the spouting direction of the washing water, as shown in FIG. 172 (a). This means that the water is discharged in a two-dimensional or substantially two-dimensional manner. In addition, the water discharge that deflects the water discharge direction of the wash water three-dimensionally is a water discharge form proposed in the present application,
As shown in FIG. 172 (b), this means that the spatial spread of the water discharge formed by deflecting the water discharge direction of the wash water is three-dimensional.

[0006] Water discharge by moving the nozzle itself in the front-rear direction or in the left-right direction is, as shown in FIG.

[0007]

SUMMARY OF THE INVENTION However, Japanese Patent Application Laid-Open No. Hei 8-2
In the technology proposed in Japanese Patent No. 84236 and Japanese Patent Application Laid-Open No. 9-60088, it is necessary to largely move a cleaning nozzle in accordance with a cleaning range in order to enable a wide range of cleaning in order not to deflect a water discharge direction.

Accordingly, when cleaning a wide area, an actuator having a large long stroke is required for driving the cleaning nozzle. In addition, a wide range of space is required for large movement of the cleaning nozzle, which hinders miniaturization of the apparatus. Furthermore, when cleaning a wide area, the driving range of the cleaning nozzle is expanded according to the cleaning area.
In order to drive the cleaning nozzle while suppressing the vibration intensity and noise value within an allowable range, it was necessary to drive the cleaning nozzle at a low speed. Therefore, it has not been possible to increase the moving speed of the predetermined trajectory of the washing water, change the speed from a low speed to a high speed, or start up at a stretch to a high speed.

Also, for the purpose of changing the part to be cleaned,
There was a demand for variably performing a wide range of cleaning and a narrow range of cleaning. However, in the above-described conventional technique, in order to secure a capability for performing a wide range of cleaning, it is necessary to perform switching between a wide range of cleaning and a narrow range of cleaning at a low speed. Was.

Further, in the technique using the fluid element mechanism for deflecting the water discharge direction, due to the characteristics of the fluid element mechanism, the moving speed (oscillation frequency) of a predetermined trajectory and the amplitude (cleaning area) of the predetermined trajectory are limited. It is determined uniformly by the instantaneous flow rate of water. That is, when cleaning a wide range, it is necessary to increase the instantaneous flow rate, and it is difficult to clean a wide range with a small flow rate. Conversely, when cleaning a small area,
It was necessary to lower the instantaneous flow rate, and it was difficult to clean a narrow range with a large flow rate. Further, when the cleaning of a wide range and the cleaning of a narrow range are variably performed, the amplitude of the predetermined trajectory (cleaning area) cannot be largely changed due to the characteristics of the fluid element mechanism, so that the change range of the cleaning area is small. In addition, as for the feeling of washing when washing the human body, the washing area and the like are uniformly determined by the instantaneous flow rate as described above.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to achieve both a cleaning capability capable of performing a wide range of cleaning performance and a reduction in the size of the apparatus, and to diversify the feeling of cleaning. And

[0012]

In order to solve at least a part of the above problems, a human body cleaning apparatus of the present invention is a human body cleaning apparatus that discharges supplied cleaning water to clean a human body. A nozzle for discharging the cleaning water toward the human body; and a water discharging direction while three-dimensionally deflecting a discharge direction of the cleaning water discharged from the nozzle at a speed independent of an instantaneous flow rate of the cleaning water. The apparatus further comprises a water discharge deflection means for cleaning the predetermined cleaning target area of the human body by scanning the cleaning water discharge along a predetermined locus.

In the human body washing apparatus of the present invention having the above-described structure, the washing water is spouted through three-dimensional deflection in the washing water spouting direction, so that a water spouting form unique to the present invention shown in FIG. A wide range of cleaning can be performed. That is, cleaning can be performed over a wide range of cleaning areas. Therefore, there is no need to drive the nozzle itself over a wide range according to the cleaning area as in the related art. Therefore, first,
The size of the entire human body cleaning apparatus as well as the nozzle itself can be reduced. Second, vibration and noise can be suppressed because nozzle driving is not required.

In order to discharge the cleaning water through three-dimensional deflection of the cleaning water discharging direction, the cleaning water discharging is scanned while the discharging direction of the cleaning water is deflected independently of the instantaneous flow rate of the cleaning water. Therefore, high-speed scanning (moving) along a predetermined trajectory of washing water spouting, variable control of the scanning speed of washing water spouting from low speed to high speed, or rapid acceleration / deceleration control of the scanning speed can be performed by increasing and decreasing the instantaneous flow rate. Can be easily executed independently and independently. For this reason, it is possible to perform cleaning by scanning the cleaning water spout at a high speed in accordance with the area to be cleaned, regardless of the increase or decrease of the instantaneous flow rate.

Further, there are the following advantages. At the time of washing the human body, a continuous and soft washing feeling can be obtained by scanning the washing water spout at high speed, and a strong intermittent stimulation can be obtained by scanning the washing water spout at low speed. Therefore, it is possible to vary only the feeling of washing without depending on the increase or decrease of the instantaneous flow rate (in other words, while keeping the instantaneous flow rate constant). Can be flexibly and easily adapted to the user's preference.

[0016] The human body cleaning apparatus of the present invention having the above configuration can also adopt the following various aspects. That is, the nozzle may include the water discharge deflection unit. In this case, the size of the nozzle and the entire human body cleaning device can be further reduced.

[0017] The water discharge deflection means may be configured such that the scanning trajectory of the washing water discharge is a movement trajectory around an axis in the nozzle, or the movement trajectory around the axis in the nozzle is a substantially rotation trajectory around the axis. It can be. By doing so, it is possible to reliably cause a three-dimensional deflection in the water discharge direction and discharge the wash water. Then, cleaning can be performed with a cleaning area having a shape defined by a movement locus around an axis in the nozzle (a circular shape in the case of a substantially rotational locus). In this case, the axis inside the nozzle means a line segment connecting the nozzle to be cleaned and the nozzle when the nozzle is arranged so that the cleaning water can be discharged from the nozzle toward the region to be cleaned. For example, when the nozzle simply discharges the cleaning water to the area to be cleaned without causing the deflection of the water discharging direction as in the present application, the line segment along the water discharging cleaning water at this time is the nozzle referred to in the present application. Can be assumed. Assuming in this manner, in the human body cleaning apparatus of the present application, the cleaning water spout is scanned along the movement locus around the above-mentioned line segment, and FIG. 172 (b) including this line segment as the center ). In addition to the movement locus around the axis in the nozzle as a substantially rotational locus about the axis, a locus along each side of the polygon surrounding the axis in the nozzle, a star-shaped or irregular-shaped contour line It can also be a trajectory along.

[0018] The water discharge deflection means may be configured to three-dimensionally deflect a water discharge angle formed by the discharged cleaning water with respect to the nozzle. Further, the water discharge deflection means may include means for substantially rotating the water discharge hole for discharging the cleaning water around an axis in the nozzle in a state where the water discharge hole is inclined with respect to the nozzle. Even in this case, the washing water can be spouted by reliably causing the three-dimensional deflection in the spouting direction.

[0019] The water discharge deflection means may be configured as a part of a flow path of washing water. With this configuration, the cleaning water is discharged with the water discharging direction deflected three-dimensionally after passing through the water discharging deflector as a part of the cleaning water flow path.

Further, the nozzle may be used for cleaning a part of the human body as a predetermined cleaning target area with the flushed water. In this way, in the local cleaning, as described above, the continuous and soft cleaning feeling by the high-speed scanning of the cleaning water spout and the strong cleaning feeling of the intermittent stimulation by the low-speed scanning can be performed regardless of the increase or decrease of the instantaneous flow rate (in other words, Then, the instantaneous flow rate can be kept constant). Therefore, not only the diversification of the washing feeling at the time of the local washing but also various users' tastes of the washing feeling can be flexibly and easily coped with. In addition, this local cleaning has the following advantages.

As in the prior art, when diversifying the washing feeling based on the washing area changed by increasing or decreasing the instantaneous flow rate, the washing water flow rate is increased or decreased. By the way, in the local cleaning, the cleaning water is heated in a heat exchanger upstream of the nozzle. Then, in such a situation where the flow rate increases and decreases, the temperature control of the heat exchanger cannot follow the instantaneous flow rate increase / decrease, and the temperature of the washing water hitting the human body local part becomes unstable and variously fluctuates. In particular, when cleaning a local part of the human body, such as in butt cleaning and bidet cleaning, temperature fluctuations in the cleaning water tend to cause discomfort due to the nature of the cleaning target being a local part. However, in the above-described human body washing apparatus of the present invention, since the sensation of washing is diversified under a constant flow rate, the temperature control of the heat exchanger can be controlled under a constant flow rate, and the temperature of the washing water can be stabilized. Can be achieved. For this reason, even if the washing feeling is made variable, the washing water having a stable temperature can be discharged to the human body, and the discomfort due to the temperature fluctuation is not given.

It is possible to have a cleaning area changing means for changing a cleaning area by the spouting water by changing the deflection amount in the water spouting direction. This way,
When switching between a wide range of cleaning and a narrow range of cleaning,
It is only necessary to change the amount of deflection in the water discharge direction three-dimensionally. Therefore, the responsiveness of switching the cleaning area between wide and narrow can be easily performed at a high speed regardless of the increase or decrease in the instantaneous flow rate, and the cleaning can be performed with the cleaning area corresponding to the area to be cleaned, regardless of the increase or decrease in the instantaneous flow rate.

Further, when the nozzle is held by hand for cleaning the human body, the cleaning area can be changed on the side of the human body cleaning apparatus as described above, so that it is not necessary to largely move the hand. Therefore, it is less likely that the hand holding the nozzle is inadvertently moved excessively and the portion other than the desired cleaning portion is erroneously wetted. In addition, when the nozzle is used for local cleaning as described above, the cleaning area can be changed on the side of the human body cleaning device without moving the human body or a part of the human body, so there is difficulty in moving the body. Even in the case or for the elderly or children, it is possible to easily and simply receive the washing in which the washing area can be switched between large and small, and the usability is good.

Further, a wide cleaning feeling in a wide range of cleaning area and a spot-like cleaning feeling in narrow cleaning can be easily used independently of the increase and decrease of the instantaneous flow rate. It is possible to flexibly and easily respond to the preference of the user for the feeling of washing. In addition, without giving discomfort based on temperature fluctuations as described above,
Wash water having a stable temperature can be discharged to the human body.

The water discharge deflecting means may repeatedly deflect the water discharge direction in a predetermined pattern. In this way, for example, a change from a wide range of cleaning to a narrow range of cleaning can be sequentially repeated. It can be washed to be repeatedly collected at the center of the wash. Therefore, not only does the cleaning object adhering to the area to be cleaned be spread unnecessarily, but also
By gathering at different locations, the cleaning efficiency can be increased.

Another human body washing apparatus of the present invention is a human body washing apparatus for washing a human body by spouting supplied washing water, comprising: a nozzle for ejecting the washing water toward the human body; The washing water is spouted while deflecting the washing water spouting direction two-dimensionally at a speed independent of the instantaneous flow rate of the washing water, and the washing water spout is scanned along a predetermined trajectory to thereby determine the predetermined position of the human body. And a water discharge deflector for cleaning a region to be cleaned, wherein the nozzle has the water discharge deflector built therein.

In this alternative human body cleaning apparatus of the present invention having the above-described configuration, the water discharge mode shown in FIG. 172 (a) is adopted, and cleaning can be performed over a wide range of cleaning area based on this water discharge mode. At this time, although the deflection dimension of the water discharge direction is different from that of the above-described invention and is two-dimensional deflection, it is the same in that it is not necessary to drive the nozzle itself at the time of deflection. Therefore, even in this other human body cleaning device, it is possible to reduce the size of the whole human body cleaning device as well as the nozzle itself and to suppress vibration and noise. Moreover, in order to discharge the cleaning water through two-dimensional deflection of the cleaning water discharging direction, the cleaning water discharging is scanned while the discharging direction of the cleaning water is deflected independently of the instantaneous flow rate of the cleaning water. Therefore, similarly to the above-described human body cleaning device, a predetermined trajectory of the cleaning water spout (for example,
High-speed scanning along the back and forth or left and right reciprocating trajectories across the axis), variable control of the scanning speed of the washing water discharge from low to high, or rapid acceleration / deceleration control of this scanning speed.
It can be easily executed independently of increase or decrease of the instantaneous flow rate. For this reason, it is possible to perform cleaning by scanning the cleaning water spout at a high speed in accordance with the area to be cleaned, regardless of the increase or decrease of the instantaneous flow rate.

In this other human body washing apparatus, the various aspects described above can be adopted similarly to the above-mentioned human body washing apparatus, and the above-mentioned advantages are obtained.

Each of the above-mentioned human body cleaning devices of the present invention can also adopt the following various aspects. That is, the water discharge deflection means may have a function of selectively changing the deflection amounts in the plurality of water discharge directions. This way,
In determining the amount of deflection in the water discharge direction, the amount of deflection in the plurality of water discharge directions can be selectively changed to only a certain amount of deflection and some other amount of deflection different from this. Therefore, the amount of deflection in the water discharge direction can be easily changed.

[0030] The water discharge deflection means may have a function of sequentially changing a plurality of deflection amounts in the water discharge direction in a predetermined order. In this way, cleaning with a cleaning area determined by a certain deflection amount and cleaning with a cleaning area determined by another deflection amount can be sequentially performed. Can be washed repeatedly. When the cleaning area is changed in width as described above, a different stimulating feeling can be given to the human body because a stimulating feeling varies depending on the cleaning area. In the case of local washing of the human body, a massage effect is obtained by repeating this stimulation, which is advantageous for promoting defecation.

The nozzle is provided with a plurality of washing water spouting holes for spouting washing water to different washing target areas to wash the areas, and the at least one of the plurality of washing water spouting holes is provided with at least one of the plurality of washing water spouting holes. The cleaning water which is deflected in the water discharging direction by the means can be discharged. Further, a plurality of nozzles for discharging the cleaning water toward the human body are provided for discharging the cleaning water to different regions to be cleaned to clean the regions, and the water discharging deflection means is provided from at least one of the plurality of nozzles. Thus, the cleaning water deflected in the water discharging direction can be discharged. By doing so, it is possible to perform cleaning with deflection of the water discharge direction only for one or a plurality of specific cleaning target areas. In particular, in the case of a device having a plurality of nozzles, an existing nozzle having no deflection in the water discharge direction may be used, so that the manufacturing is simplified.

A setting means for setting the deflection amount in the water discharge direction, and a control means for controlling the water discharge deflection means so as to have the set deflection amount and discharging the washing water in the water discharge direction with the set deflection amount. Can be included. Setting means for setting the amount of deflection in the water discharge direction for each of the plurality of cleaning target areas; and controlling the water discharge deflection means so as to have the set amount of deflection to set deflection for each of the plurality of cleaning target areas. And control means for discharging the washing water in the direction of discharging the amount of water. In this way, a feeling of cleaning and a feeling of comfort based on the set amount of deflection in the water discharge direction can be achieved.
It can be obtained reliably and promptly.

Further, by controlling the cleaning area changing means,
If the cleaning area is changed over time or periodically, the cleaning feeling based on the cleaning area changes with time and periodic fluctuation, which is useful for diversification of the cleaning feeling.

At this time, the change in the washing area may be induced so that the human body does not recognize the change in the washing area due to the washing water as a stimulus change. In this way, the washing area can be changed without causing the human body to feel that the washing feeling or the feeling of comfort based on the washing area has changed. In addition, the flow rate of the cleaning water can be reduced independently of the fluctuation of the cleaning area. Therefore, even if the flow rate of the washing water is reduced, the feeling of washing and the feeling of comfort based on the washing area can be maintained.
The effectiveness of water saving can be further improved.

The following method can be used to induce a change in the cleaning area so that the human body does not recognize that the cleaning area has changed. Fluctuation of washing area is about 0.3
When the change occurs in a cycle of about seconds, the change can be clearly recognized by the human body as a stimulus change. Therefore, it is preferable that the above-described change in the cleaning area occurs in a short cycle of about 0.2 seconds or less. If the change in the washing area occurs at a frequency of about 3 Hz or less, the change can be clearly recognized as a stimulus change by the human body. Therefore, it is preferable that the above-described change in the washing area occurs at a frequency of 5 Hz or more. In this case, the meaning of preventing the human body from recognizing as a stimulus change in the present application means intentionally causing the human body not to be recognized as a stimulus change. Therefore, some stimulation change (for example,
Compared with massage washing in which the human body recognizes a stimulus change based on a temperature change or a flow rate change, it differs in that the stimulus change is not recognized but is common in that intentional water discharge control is performed. That is, the stimulus change referred to in the present invention is a stimulus change inevitably occurring in washing water spouting or continuation of washing water spouting in any form of washing water spouting. It does not include frequency / period stimulus changes that occur inevitably.

Each of the above-mentioned human body cleaning devices of the present invention comprises a command means for instructing the start of cleaning of the human body, and the water discharge deflection means being controlled in synchronization with the cleaning start command from the command means, and Change control execution means for executing the deflection of the water discharge direction by the means. In this way, when a cleaning start command is issued, the washing water is spouted with the deflection of the spouting direction at all times, and the human body can be washed by spouting the washing water while deflecting the spouting direction as described above.

B1 / water channel system / control system configuration: The local cleaning apparatus of this embodiment has the following water channel system configuration and control system configuration for performing the cleaning operation / drying operation, etc., corresponding to the above-mentioned buttons. As shown in FIG. 4, the waterway system of the local cleaning device includes:
From an external water source (not shown), the water inlet valve unit WP
1-1, a heat exchange unit TH1-1, and a water discharge side valve unit WP1-3. Then, the washing water is guided from the water discharge side valve unit to the washing nozzle WN1-1 of the nozzle device NS1-1, and the washing water is discharged from the nozzle as described later. Further, from the water discharge side valve unit, the cleaning water is also guided to the functional water units WP1-4, and the functional water is discharged from the unit toward the cleaning nozzle WN1-1. These units are connected by upstream and downstream water supply lines across the heat exchange unit. That is, the inlet side valve unit and the heat exchange unit are connected to the upstream side water supply line WP1-
5, each unit downstream of the heat exchange unit and the nozzle device are connected by a downstream water supply line WP1-6. In this case, the outflow-side valve units WP1-3
Water supply pipelines are branched, and three of them are nozzle devices N
At S1-1, the rest is connected to the functional water units WP1-4. These branch pipes also form part of the downstream pipe.

The upstream water supply pipe line WP1-5 is connected to the water inlet valve unit WP1-1 so as to directly supply cleaning water (tap water) from a water supply source (water pipe) to the main cleaning device. The washing water guided to the upstream water supply pipe flows into the check valve WP1-8 and the constant flow valve WP1-9 after catching dust and the like by the strainer WP1-7 of the water inlet valve unit. Then, when the conduit is opened by the solenoid valve WP1-10 downstream of the constant flow valve, the washing water flows into the heat exchange unit TH1-1 of the instantaneous heating method in a state where the flow rate is set to a predetermined flow rate by the constant flow valve. . In this embodiment, about 500 to 1
The cleaning water flow rate is set to about 000 cc / min. The upstream water supply pipe WP1-5 may be branched from a flush water tank (not shown) for storing flush water for flushing the toilet and piped to the water inlet valve unit WP1-1.

[0045] A relief valve WP1-1 is provided in the upstream water supply line between the water inlet valve unit and the heat exchange unit.
1 and a second washing water outlet pipe WP branched directly from the upstream water supply pipe.
1-13 are provided. The first washing water outlet pipe draws out the washing water in the upstream water supply pipe when the pipe pressure on the upstream side of the relief valve rises for some reason and the pipe is opened by the relief valve. As a result, it is possible to avoid an increase in the tank internal pressure in the upstream water supply pipe, and hence the heat exchange unit. You don't have to. Further, the second washing water outlet pipe is connected to a set flow rate at the constant flow valve and a flow regulating pump WP1-14 described later in the downstream water supply pipe WP1-6.
The cleaning water with a flow rate that is different from the adjusted flow rate in step (1) is led out. Thus, it is possible to omit useless washing water hot water in the heat exchange unit, and it is possible to reduce power consumption.

The first and second washing water outlet pipes are arranged such that their ends face the deodorizing intake port and the local drying exhaust port. Therefore, the washing water derived from the two conduits is discharged to these intake ports and exhaust ports. Since the intake port and the exhaust port face the bowl portion of the toilet bowl, they may be contaminated by splashing water of dirt disposed on the ball portion. However, since the intake port and the exhaust port are washed with the washing water from both the above-mentioned outlet pipes, it is preferable from the viewpoint of hygiene and cleanliness. Note that the flush water spouted from the outlet pipe flows down to the bowl bowl portion and does not stain the periphery of the toilet bowl.

The heat exchange unit TH1-1 downstream of the water inlet valve unit has a tank TH1-3 containing a heater TH1-2. This heater is configured by spirally winding a nichrome wire having good thermal responsiveness. Therefore, the tank only needs to have a capacity capable of instantaneously heating the washing water by the heater, so that the size of the tank and thus the entire heat exchange unit can be reduced. Further, since the structure of the heat exchange unit is simplified, there are advantages in manufacturing such as a reduction in the number of assembling steps and a reduction in cost. A bimetal or a thermal fuse (not shown) for mechanically shutting off abnormal heating is attached to the heater or its vicinity.

The heat exchange unit measures the temperature of the washing water flowing into the tank and the temperature of the washing water flowing out of the tank by using an inlet water temperature sensor SS16a and an outlet water temperature sensor SS16b.
The heater is used to warm the cleaning water to the cleaning water at the set temperature while detecting the temperature. In this case, if the heat exchange unit is covered with a heat insulating material such as a foam material, the power consumption of the heater for warming the cleaning water can be reduced together with the effect of keeping the cleaning water warm by the heat insulating material. That is, the energy saving effect increases.

This heat exchange unit has a float switch SS18 for detecting the water level in the tank. The float switch is configured to output a signal to that effect when the temperature of the heater becomes equal to or higher than a predetermined water level at which the heater is submerged.
Then, since the electronic control unit CT1-1 controls the energization of the heater under the condition that this signal is input, it is possible to avoid a situation in which it is likely to energize a heater that is not submerged, that is, a so-called empty heater. . The heater of the heat exchanger unit is optimally controlled by a later-described electronic control device while combining feed-forward control and feedback control.

Further, this heat exchange unit is provided with a vacuum breaker TH1-4 at a washing water outlet from the tank, that is, at a tank connection point of the downstream water supply pipe line WP1-6. This vacuum breaker introduces air into the pipe to cut off the washing water in the downstream water supply pipe, and prevents backflow of the wash water from the downstream side of the downstream water supply pipe.

The water discharge side valve unit WP1-3 downstream of the heat exchange unit has a flow regulating pump WP1-14 composed of a gear pump and the like and a switching valve WP1-15 having a five-way valve structure. This switching valve directs the supply destination of the washing water to the ass washing flow path, the soft cleaning flow path, the bidet cleaning flow path, and the flow path to the functional water unit WP1-4 to the cleaning nozzle WN1-1. Water channel). Therefore,
Wash water that has been heated by the heat exchange unit and flow-adjusted by the flow control pump is discharged from the water supply destination switched by the switching valve. At this time, the flow rate adjustment and the water supply destination switching will be described later.

The control system of the local cleaning device of this embodiment is shown in FIG.
As shown in FIG. 1, the electronic control unit CT1-1 mainly includes a microcomputer. This electronic control unit includes various sensors such as the above-mentioned seating sensor, incoming / outgoing water temperature sensor and the like, a float switch, signals from swing detection circuits NH1-39, NH40, a fall detection sensor SS30, and a washing water amount sensor SS14. The operation states of the various operation buttons and the knobs on the remote operation device and the auxiliary operation unit on the main body side are described below.
Input via a wired or wireless (optical signal) via an input circuit. In this case, the washing water amount sensor detects the amount of washing water in the downstream water supply pipe, and outputs the detection result to the electronic control unit. The fall detection sensor detects the inclination state of the main cleaning unit and outputs the result to the electronic control unit. The electronic control device controls the solenoid valve on / off valve of the water inlet valve unit WP1-1, the heater energization control of the heat exchange unit TH1-1, and the water outlet valve unit W based on the input signal.
P1-3 flow control pump control, switching valve switching control, display control of main body sleeve display section, energization control of drying section KK1-1 including drying heater and fan motor for local drying, ozonizer for odor removal, etc. Deodorizing section DS including suction fan motor etc.
In addition to executing power supply control of 1-1 and power supply control of a heating unit DB1-1 including a heater and a fan motor for indoor heating, based on the signal, a chlorine generation electrode of a functional water unit WP1-4 described later. The energization control, the nozzle drive motor control of the nozzle device NS1-1, and the oscillation coil group energization control of the nozzle head NH1-1 are executed. Note that the drying heater for local drying can be shared with a heater for indoor heating, and the fan motor for local drying can be shared with a fan motor for odor removal or indoor heating.

For example, when the local cleaning device is removed from the toilet for cleaning or the like and leans against the toilet, the signal of the float switch may be normal. In such a case, the heater may be exposed, but the signal of the float switch is normal, and there is a possibility that the heater may be idle. However, the tilt detection sensor detects this inclination by leaning on the toilet, and upon receiving the signal, the electronic control unit stops energizing the heater to prevent empty heating. In addition, the solenoid valve and the like are controlled to be closed so that the water is stopped, and various functions such as drying and deodorizing are stopped. That is, the fall detection sensor can detect the normal mounting state of the local cleaning device on the toilet, and as a result, the functions (cleaning, drying, deodorizing, and room warming) of the local cleaning device can be temporarily stopped. Other device controls will be described later. A limit sensor consisting of a thermistor or a temperature-sensitive reed switch is provided at the tip of the cleaning nozzle and connected to the electronic control unit. It can be in water. This is preferable because it is possible to more effectively avoid discharging the cleaning water having an inadvertent temperature to the local area.

C1 / Nozzle Device NS1-1: Next, the nozzle device NS1-1 of the local cleaning device of this embodiment will be described. FIG. 6 is a schematic perspective view showing the nozzle device NS1-1, FIG. 7 is an explanatory diagram for explaining how the cleaning nozzle WN1-1 moves forward and backward, and FIG. 8 is at a standby position in the local cleaning device main body. It is explanatory drawing showing the periphery of a washing | cleaning nozzle front-end | tip part.

As shown, the nozzle device NS1-1
Is stored and installed in the main body KS1-2 (see FIG. 1) of the local cleaning device. The nozzle device includes a base NS1-2 fixedly installed on the main body, and a gantry N on an upper surface of the base.
Nozzle drive motor NS1 incorporated in S1-3
-4, a transmission mechanism NS1-5 for converting the forward / reverse rotation of this motor into a forward / backward movement and transmitting the forward / backward movement to the washing nozzle WN1-1, and a washing nozzle erected on the upper surface of the base so that the washing nozzle is slidable on the toilet bowl side. It has a nozzle holding portion NS1-6 for holding, and a guide rail portion NS1-7 for guiding the cleaning nozzle along a nozzle advance / retreat trajectory described later.

The transmission mechanism NS1-5 includes a drive pulley NS1-8 fixed to the rotation shaft of the nozzle drive motor NS1-4.
And driven pulleys N before and after along the nozzle advance / retreat trajectory.
S1-9, a timing belt NS1-10 stretched over these pulleys, and a tension roller NS1-11 for applying tension to the belt. The timing belt is engaged with and fixed to the cleaning nozzle WN1-1 via a belt holding body WN1-2 extending from the cylindrical portion WN1-4 of the cleaning nozzle WN1-1. Therefore, this cleaning nozzle
The timing belt is driven forward and backward according to the forward and reverse rotation of the timing belt.

The guide rail portion NS1-7 is formed to be curved so as to coincide with the arc-shaped nozzle advance / retreat trajectory NS1-12 shown in FIG. 7, and the track gripper W extending from the cylindrical portion.
It is engaged with the nozzle via N1-3. The track gripper has a track gripping surface having the same radius of curvature as the nozzle advance / retreat track, and the track gripping surface is slidable with respect to the guide rail. In addition, the above-described nozzle holding unit NS
1-6 slidably holds the cleaning nozzle. Therefore,
When the cleaning nozzle WN1-1 is driven forward and backward by the timing belt, the cleaning nozzle WN1-1 is driven forward and backward along the guide rail portion NS1-7, and its movement trajectory coincides with the arc-shaped nozzle forward and backward trajectory NS1-12. In this case, even in the case of the washing nozzle, the cylindrical portion WN1-4 has a curved radius along the axial direction with the same radius of curvature as the nozzle advance / retreat trajectory.
For this reason, the cleaning nozzle moves back and forth between the standby position HP in the main body and the cleaning position (butt cleaning position AWP, bidet cleaning position VWP) in the toilet bowl portion in accordance with the arc-shaped nozzle advance / retreat trajectory. Drive. The nozzle holding unit NS1
No. -6 is configured to only partially contact the nozzle outer wall in order to reduce the sliding resistance of the cleaning nozzle.

As a result, as shown in FIG.
The cleaning nozzle WN1-1 of P can be mounted on the nozzle device NS1-1 so as to approach the upper surface of the toilet bowl along its axial direction. Therefore, the height of the rear end of the washing nozzle (nozzle height) from the upper surface of the toilet can be made lower than when the cylindrical washing nozzle advances and retreats along an inclined straight orbit. Therefore, the main body portion KS1-2 (see FIG. 1) is reduced by the reduced nozzle height.
And the size of the local cleaning device itself can be reduced. Further, since the angle of the upper surface of the nozzle head changes due to the advance of the nozzle, and the angle of spouting the washing water from the head changes, the washing range can be largely moved with a small nozzle movement. Specifically, even if the reciprocating range of the nozzle during the move cleaning described below is narrowed, the cleaning water can be discharged over the cleaning range required for the move cleaning. Alternatively, even if the nozzle moving distance from the buttocks washing position AWP to the bidet washing position VWP is short, the washing location with the washing water can be changed from the buttocks to the bidet.

D1 / functional water unit WP1-4;
Functional water unit W prior to description of washing nozzle WN1-1
P1-4 will be described. FIG. 9 shows the functional water unit W
FIG. 10 is a schematic cross-sectional view taken along the line 10-10 in FIG.

As shown, the functional water units WP1-4
Is a functional water generation tank WP1-16 fixedly installed in the nozzle device NS1-1 (refer to FIG. 6), and a pair of flat-plate-like chlorine generation electrodes WP1-1 opposed to each other in the tank.
And 7. The functional water generation tank is a resin tank having chemical resistance (free chlorine resistance), and the washing water flowing into the tank from the inner pipe WP1-18 flows into the outer pipe WP1-19. . As shown in FIG. 6, FIG. 8 and FIG.
It is fixed to the chamber NS1-14 at the tip of 1-6. In addition, the in-side pipeline and the out-side pipeline are arranged facing each other,
The cleaning water may flow efficiently in the tank.

Here, the chlorine generation electrode is an electrode capable of inducing a chlorine generation reaction, and has an electrode structure in which an electrode shape is formed of a conductive base material and a chlorine generation catalyst is supported on the surface thereof. And a structure in which an electrode is formed using a conductive material composed of a chlorine generation catalyst. Electrodes for chlorine generation of this latter structure are variously referred to depending on the type of catalyst for chlorine generation, for example, iron-based electrodes such as ferrite, palladium-based electrodes, ruthenium-based electrodes, iridium-based electrodes, platinum-based electrodes, ruthenium-tin. System electrode, palladium-platinum system electrode, iridium-platinum system electrode, ruthenium-platinum system electrode, iridium-platinum-tantalum system electrode and the like. In the case where the chlorine-generating catalyst is supported on the conductive base material, the base material for the structure can be made of inexpensive materials such as titanium and stainless steel, which is advantageous in manufacturing cost. In particular, when using tap water having a chlorine ion content of only about 3 to 40 ppm in the chlorine ion-containing water, an iridium-based electrode supporting iridium and an iridium-platinum alloy in order to improve the generation efficiency of free chlorine. An iridium-platinum-based electrode carrying iridium, a iridium-platinum-tantalum-based electrode carrying an iridium-platinum-tantalum alloy, and the like are suitable. In addition, when using a catalyst in which a chlorine-generating catalyst is supported on a conductive base material as described above, when a platinum-containing alloy catalyst is supported, the fixing strength to the base material is increased, so that desorption does not easily occur. It is preferable because the life can be improved.

A DC voltage is applied to the chlorine generating electrode such that one is an anode and the other is a cathode. Wash water supplied to the functional water unit is tap water containing chlorine ions that is a source of free chlorine generation. Therefore, by applying a DC voltage in a state where the washing water is stored in the tank of the functional water unit, free chlorine is generated on the anode side. Since free chlorine has a bactericidal effect on bacteria such as Escherichia coli adhering to the cleaning nozzle, the cleaning water enriched in free chlorine in the functional water unit (hereinafter referred to as functional water) is supplied to the cleaning nozzle in the nozzle holding section. By spouting the water, the propagation of bacteria can be prevented, which is sanitary. The state of the functional water spouting will be described later.

In the above functional water unit, approximately 50 cc of tap water is stored in the tank, and when a voltage of 24 VDC is applied to the chlorine generating electrode for approximately one minute, functional water having a free chlorine concentration of approximately 1.5 ppm is generated. The electrode area and the distance between the electrodes are determined so as to make it possible, and the electronic control unit controls the energization of the chlorine generating electrode (constant voltage control). In this case, when the electric conductivity of the washing water is high and the current flows too much between the electrodes, the applied voltage is set to a low value to extend the life of the electrodes and prevent heat generation in the current-carrying part. Further, the applied voltage may be changed as needed in accordance with the electric conductivity of the washing water, and the control of energization to the chlorine generation electrode may be controlled by constant current control or constant power control. The electronic control unit performs a certain period of time (approximately 1
Minutes), the power supply is stopped. As a result, it is possible to avoid problems such as excessive generation of free chlorine, an inadvertent increase in free chlorine concentration, a reduction in electrode life, and generation of bubbles due to excessive electrode heating.

The functional water generated by the functional water unit is discharged to the nozzle head NH1-1 for nozzle cleaning in pre-nozzle cleaning and post-nozzle cleaning (see FIGS. 25, 26, and 30) described later. In addition, to fulfill the sterilization function,
Water is discharged at the following timing. That is, a timing based on detection of a user's use state (for example, detection of a seating sensor or a cleaning operation), a periodic timing every predetermined time,
For example, at the timing of a timer such as 6:00 in the morning, 12:00 in the daytime, and 11:00 at night, the functional water is discharged from the out-side pipe line WP1-19 to the nozzle head NH1-1. Even with the functional water spouting performed at each of these timings, in the case of a storage type that is used after generating the functional water in advance, the timing of generating the functional water is the same as the timing described above, and The energization for generating functional water is stopped when a certain time has elapsed from the start of energization. In this case, the execution timing of the periodic discharge of the functional water performed at the above-described regular timing can be set arbitrarily, such as every two hours or every four hours. When the functional water spouting is performed at these timings, the flow control pump WP1 suitable for the functional water spouting is used.
The flow rate is adjusted by -14 and the flow path is switched to the functional water flow path by the switching valve WP1-15. Further, as described above, the tank of the functional water generation unit is not limited to the storage type (50 cc storage), but may be a type in which the water passage is sandwiched between chlorine generation electrodes. In this type, the above-described electrode energization control is executed at each of the above-described timings, and each time functional water is discharged through flow path switching.

E1 / cleaning nozzle WN1-1 and nozzle head NH1-1; Next, the cleaning nozzle WN1-1 will be described. 11 is a schematic sectional view taken along line 11-11 of FIG. 8, FIG. 12 is an enlarged schematic perspective view of the nozzle head NH1-1 at the tip of the cleaning nozzle, and FIG. 13 is a schematic sectional view taken along line 13-13 of FIG. 14 is a plan view of the nozzle head base NH1-2.

As shown in FIGS. 6 to 8, the cleaning nozzle WN1-1 has a curved cylindrical portion WN1-4 and a nozzle head NH1-1 at the tip thereof. This cylindrical part is shown in FIG.
As shown in FIG. 1, storage chambers WN1-5 divided vertically are provided in the longitudinal direction of the nozzle. The upper and lower storage chambers are shut off (separated) from each other by a central wall, and are closed by a cover portion WN1-6 at an appropriate position on the outer peripheral wall of the tubular portion. A flat cable NH1-42 to be described later is stored in the upper storage chamber. The flat cable NH1-42 is taken out from the end of the cleaning nozzle and connected to the electronic control device described above. The flat cable and a flexible tube to be described later are stored and assembled in the storage room without any trouble with the cover part removed.

In the lower storage room, three flexible tubes are stored.
First nozzle flow path WN1- serving as a bottom cleaning nozzle flow path
7. Second nozzle flow path W to be a soft cleaning nozzle flow path
N1-8 and a third nozzle channel WN1-9 serving as a bidet cleaning nozzle channel. These flexible tubes are connected via a tube connecting portion (not shown) at the end of the nozzle to a flow path for cleaning the tail, a flow path for soft cleaning, and a flow path for bidet cleaning downstream of the switching valve WP1-15 in FIG. . Each flexible tube is shown in FIGS.
As shown in (1), the first base channel NH1-3 serving as a base cleaning channel for the tail end of the nozzle head base NH1-2 projecting from the distal end of the cylindrical portion, and the second base channel serving as a base channel for soft cleaning. NH1-4 and a third base channel NH1-5 serving as a bidet cleaning base channel. Therefore, when the switching valve WP1-15 (see FIG. 4) switches the supply destination of the washing water to any one of the downstream buttocks washing channel, the soft washing channel, and the bidet washing channel, the washing water is supplied. The water flows into the nozzle flow path / base flow path through the switched flow path, and is discharged from each of the water discharge holes described later of the nozzle head. The first to third nozzle channels WN1-7 to WN9 may be formed in the cylindrical portion WN1-4 at the time of molding.

The nozzle head NH1-1 has a nozzle passage
The following configuration is provided to discharge the washing water flowing into the base flow channel toward a local portion. This nozzle head is configured by mounting a head cover NH1-6 on a nozzle head base NH1-2. This head cover includes a buttocks movable body NH1-9 having a buttocks spout NH1-7 used for normal ass washing and a soft spout NH1-8 used for soft washing of the buttocks, and a bidet spouting hole used for bidet washing. NH1-
And a bidet movable body NH1-11 having the front and rear surfaces 10 on the upper surface of the cover. Also, this head cover is shown in FIG.
, The cover-side engaging claw portion NH1-13 which engages with the engaging claw portion NH1-12 on the upper edge of the nozzle head base.
And an engagement projection NH1-14 protruding from the rear peripheral wall. The cover-side engaging claw portion is formed over the front side peripheral wall excluding the rear peripheral wall. Further, since the leading end of the engaging protrusion is formed with a cross-shaped slit, the engaging protrusion is contracted or expanded at the leading end to form the cylindrical portion WN1.
-4 can be inserted into and removed from the front end wall through hole. Accordingly, the head cover NH1-6 slides along the outline arrow in FIG.
It is attached and detached. That is, this head cover is replaceable.

Here, the movable body will be described.
FIG. 15 shows a bidet movable body NH1-11 used for bidet cleaning.
FIG. 16 is a schematic plan view illustrating the bidet movable body and its related members, and FIG. 17 is a schematic perspective view illustrating the bidet movable body and the related members.

As shown in FIGS. 12, 13 and 15, the movable body for bidet NH1-11 includes a head cover NH1.
-6, a flange portion NH1-15 fixed to the upper surface of the cylinder -6, a cylindrical portion NH1-16 at the center thereof, and a water discharging piece NH1- located at a central through hole of the cylindrical portion and having a bidet water discharging hole NH1-10 at the center. 17 and a magnetic driver NH at the lower end of the water discharge piece.
1-18. The flange portion NH1-15 and the cylindrical portion NH1-16 are formed of an elastic material such as rubber, elastomer, or the like that exhibits a deformation restoring property. In order to prevent sewage from adhering to the elastic material or prevent the elastic material from deteriorating due to functional water spouting, the surface of the elastic material is subjected to a water repellent treatment (for example, a fluorine coating treatment).
It is preferable to apply a hydrophilic treatment (for example, coating with titanium oxide). The water discharge piece NH1-17 is a resin molded product, and the lower end of the bidet water discharge hole of the water discharge piece is a large-diameter water discharge guide hole NH1-19. Magnetic driver NH1-
Reference numeral 18 denotes a press-formed product of a water-resistant and rust-proof magnetic material, for example, an electromagnetic stainless steel plate, which is integrally formed with the water discharging piece NH1-17 by an insert molding method or the like. Generally, the material of the magnetic driving body may be a soft magnetic material that is a high magnetic permeability material, and examples thereof include silicon steel, ferrite, and pure iron. It is preferable to aim. Since this water discharge piece is fitted and fixed in the central through hole of the cylindrical portion, the bidet movable body NH1
Reference numeral -11 denotes a sub-assembly made of the above members. And this movable body for bidet, at the peripheral edge of the flange,
It is fixed to the head cover by an appropriate method such as an adhesive, welding, or screwing. For this reason, the bidet movable body NH1-11
Can be swung in each direction by deforming and restoring a connecting portion between the flange portion and the cylindrical portion while being supported by the flange portion and hung down.

The magnetic driver NH1-18 has magnetic action parts NH1-18a-18c on the periphery. Therefore, when a magnetic attraction force acts on each magnetic acting portion, the corresponding magnetic acting portion moves downward, and the bidet discharge hole is inclined in accordance with the downward movement of the magnetic acting portion. Then, by energizing and sequentially energizing an electromagnetic coil, which will be described later, which is disposed circumferentially at a predetermined interval corresponding to each magnetic acting portion in a counterclockwise or clockwise direction, the magnetic coil attracted by the energized electromagnetic coil Since the action portion sequentially moves, the bidet discharge hole also moves three-dimensionally in a counterclockwise and clockwise order while being inclined accordingly. The swing angle of the bidet spout hole (spout angle of the spout hole α: see FIG. 16) adjusts the strength of the suction force, that is, adjusts the voltage value (ie, current value) of the energizing voltage of the electromagnetic coil. It can be changed by adjusting the duty ratio of the energizing voltage. Further, since it is sufficient to apply a suction force enough to cause deformation at the flange connecting portion, the bidet movable body NH1-11 easily swings.

Although the buttocks movable body NH1-9 has the above-mentioned two water discharge holes, it differs from the above-mentioned bidet movable body in its shape, but is a member that performs the same function as this bidet movable body. Have. Therefore, the description thereof will be omitted, and the drawings will be given only reference numerals.

If the magnetic driver is made of a hard magnetic material, not only the attractive force but also the repulsive force can be applied to the magnetic driver by the magnetic force exerted on the magnetic driver. On the other hand, in the case of a soft magnetic material as in the present embodiment, an attractive force can be applied to the magnetic driving body by a magnetic force.

Next, the magnetic force generator NH1-26 which swings the movable body as described above will be described. FIG.
FIG. 19 is a schematic exploded perspective view illustrating the magnetic force generator NH1-26, FIG. 19 is a plan view of an electromagnetic coil installation substrate NH1-28 of the magnetic force generator, and FIG. 20 is a circuit configuration formed on the upper surface of the substrate. FIG.

As shown in FIGS. 12 and 13, the magnetic force generator NH1-26 is in a non-contact state with the above-mentioned two movable bodies, that is, in a state where a gap is secured between the lower ends of the movable bodies.
In addition, the nozzle head base NH1- is provided with a gap left between the front and left and right side walls of the nozzle head base.
2 is fixedly installed on the upper surface. In the front and left and right side walls of the base, a gap between the side wall and the magnetic force generating body is provided with an outside air suction hole NH1-2 communicating with the outside of the nozzle head.
7 is empty. In this case, the opening area of each outside air suction hole is determined as follows. When the cleaning water is discharged from each of the water discharge holes of the buttocks, the soft, and the bidet, the cleaning water passes through the gap at the lower end of the movable body because the flow path diameters above and below the gap are wide and narrow as shown in FIG. In this case, an ejector action occurs. Therefore, air is entrained in the washing water and is mixed in a foamy state. At this time, the air mixing rate is about 50-100.
%, The opening area of the outside air suction hole is determined in consideration of the flow path diameter before and after the gap. The opening position of each outside air suction hole on the side wall of the nozzle head base is lower than the lower surface of the magnetic force generator, and the front wall of the base is a sloped front end. Therefore, even if the washing water rebounds to the nozzle head during the cleaning operation, it is possible to prevent the repelling cleaning water from entering the inside of the nozzle head through the outside air suction hole. Further, it is possible to prevent the dirty washing water during the head washing with the brush or the like from entering the inside of the nozzle head. Further, the cleaning water leaked from the gap at the lower end of the movable body during the discharge of water from the water discharge holes of both movable bodies,
It is transmitted to the top and side surfaces of the magnetic force generator and discharged from each outside air suction hole. For this reason, the magnetic force generator, and furthermore, an electromagnetic coil described later therein can be cooled by the discharged washing water, so that a change in coil characteristics due to heat generation can be suppressed. In addition, since the outside air suction holes are provided corresponding to the respective movable bodies, there is no stagnation of the discharged washing water, and the cooling effect can be enhanced. The outside air suction hole may be provided only on the front wall of the base.

As shown in FIG. 18, the magnetic force generator NH1-
26 has an electromagnetic coil installation substrate NH1-28 on which various members described later are installed, and a frame NH1-29. This substrate is resin-molded by pouring a thermosetting resin into the frame of the frame, and is a sub-assembly integrated with the frame. In this case, the tip of each of the coil cores described later and the water supply ports NH1-46 to 48 installed on the substrate are
It is exposed to the outside. Therefore, there is no inconvenience due to leakage of coils, circuits, and the like, which will be described later, provided on the substrate.

The electromagnetic coil installation substrate NH1-28 is used to swing the hip swing coil group NH1-30 for swinging the hip swing body NH1-9 and the bidet movable body NH1-11. Rocking coil group NH1-31 for bidet. Each oscillating coil group includes a magnetic operating portion NH1-18a of a magnetic driver NH1-18, 23 of each movable body.
To 18c, 23a to 23c, and three electromagnetic coils NH1-32a to 32c, 33a to 33c. The respective electromagnetic coils are disposed and fixed to the substrate so as to face the respective magnetic action portions of the magnetic driving body.

Each of the electromagnetic coils has the same configuration, is provided with two coil cores NH1-35 standing on a plate NH1-34, and one coil core has a coil. Thus, when the coil is energized, the electromagnetic coil is excited to form a magnetic flux (see FIG. 17) looping between the plate and the two coil cores. In this case, when the nozzle head is completed,
Since the two coil cores and the corresponding magnetically acting portions are opposed to each other, the above-described magnetic flux loops using the magnetically acting portion of the magnetic driving body as a magnetic path. Then, the electromagnetic coil exerts an attractive force based on a magnetic force in accordance with the energization of the coil, on the opposing magnetic action portion. In other words, when the electromagnetic coil is excited, a magnetic flux passing through the opposing magnetic action parts is formed, and the magnetic action parts have opposite poles corresponding to the respective coil cores, that is, the S poles are applied to the magnetic action parts on the N pole iron cores. Since the poles are formed on the magnetic poles and the N poles are formed on the magnetic poles of the S pole cores, the action portions are attracted to the respective coil cores. Even if the direction of the flowing current is changed, the polarity is N
The suction force acts in the same manner simply by reversing the steps S and S.
Moreover, the strength of the attraction force due to the magnetic force can be controlled through control of energization of the coil. This plate and 2
Since both coil cores are made of ferromagnetic material,
The formation of the magnetic poles described above becomes remarkable, and an attractive force based on a strong magnetic force can be exerted on the magnetic action portion. Due to the action of the magnetic force of the electromagnetic coil, the two movable bodies and the water discharge holes thereof swing as described above, and the water discharge hole swing angle α (see FIG. 16) at that time is controlled by controlling the power supply to the coil Is controlled as described later. In the following explanation,
For the sake of convenience, as shown in FIG.
The coils in each of the electromagnetic coils 1-30 are NH1-30
a to 30c, and the coils of the bidet swing coil group NH1-31 are denoted by NH1-31a to 31c.

The circuit shown in FIG. 20 is formed on the electromagnetic coil installation substrate NH1-28 by a printing method in order to excite the respective electromagnetic coils in the rocking coil group for the hips and bidet. . That is, this substrate is provided with a power supply line and a ground line of a predetermined DC voltage, and coils NH1-30a to 30c of the hip rocking coil group NH1-30.
And coil NH1-31 of bidet movable body NH1-11
transistors Tr1 to Tr6 connected to a to 31c to turn on and off the current to each coil; a base line for adjusting a base voltage via resistors R1 to R6 to turn on and off each of the transistors Tr1 to Tr6; It has output lines NH1-36 and 37 for outputting the state of current supply through the resistors R7 and R8 for voltage adjustment.
The resistors R7, R8 and the output lines NH1-36, 37 constitute swing detection circuits NH1-39, NH40 shown in FIG. 5, and a state of occurrence of abnormal coil energization, that is, occurrence of abnormal swing of the movable body will be described later. Is detected. Each line in this circuit is connected to a flat cable NH1-42 at a terminal at the end of the board, and is connected to the electronic control unit CT1-1 via the cable. In this case, the transistors Tr1 to Tr6 and the resistors R1 to R8 can be installed as a coil control circuit (not shown) in the electronic control device, so that the magnetic force generator and thus the nozzle head can be downsized. Also, the resistors R7 and R8 and the output line NH
The swing detection circuit NH1-3 composed of 1-36 and 37
9 and 40 are for detecting the occurrence of coil energization abnormality, and therefore can be configured as follows. That is, a position detection device such as a Hall IC or an optical sensor is used in place of the two resistors, and the movement of the object to be driven (such as a magnetic acting portion) by the electromagnetic coil is detected by the position detection device. Then, a swing detection circuit is configured to detect the occurrence of coil energization abnormality based on the detection result of the position detection device. When the substrate is installed on the nozzle head base NH1-2, as shown in FIG. 13, a flat cable is assembled with a rubber bush NH1-43 interposed.

Also, the electromagnetic coil installation substrate NH1-28
Has the following configuration in order to supply cleaning water to the movable body in addition to the swing coil group for swinging the movable body. That is,
As shown in FIG. 13 and FIG. 18, the substrate has a first protruding portion NH1-4 surrounded by a hip rocking coil group NH1-30.
4 and the second surrounded by the bidet swing coil group NH1-31.
It has a protrusion NH1-45. The first protruding portion has an inner bottom water discharge hole NH1-46 communicating with the first base flow path NH1-3 of the nozzle head base NH1-2, and a soft water discharge inside the head communicating with the second base flow path NH1-4. Hole NH

10 are opposed to each other with the gap described above. Therefore, when the switching valve WP1-15 (see FIG. 4) switches the supply destination of the washing water to any one of the downstream buttocks washing channel, the soft washing channel, and the bidet washing channel, the washing water is supplied. The water is supplied to the movable body through the nozzle flow path, the base flow path, and the above-described water discharge holes in the heads via the switched flow paths, and water is discharged from the water discharge holes of the movable bodies. In addition, during the flushing of the wash water from each of the water discharge holes, the above-described air entrapment at the time of passing through the gap between the base flow path and the water discharge hole occurs, and the cleansing water contains air in a foamy state. It is spouted.

In this case, each of the water discharge holes NH1 in the head
-46 to -48 are smaller than or equal to the diameter of the tail water discharging hole, the soft water discharging hole, or the bidet water discharging hole of each movable body (in this embodiment, the same diameter as the opposed water discharging hole). Therefore, the spouting speed of the washing water spouted locally is determined by the diameter of the bottom spout hole, the soft spout hole, or the bidet spout hole of each movable body. Each of the water discharge holes of each movable body has the smallest diameter of the bottom water discharge hole, and the diameter of the bidet water discharge hole is softer than that of the bottom water discharge hole. For this reason, if the water pressure is set to be constant by the water pressure setting buttons SWhu and SWhd of the remote control device RC1-1 (see FIG. 2), the flush water is discharged from each water discharge hole of each movable body. The speed is the fastest in the buttocks spout, and slower in the bidet and soft spouts than in the buttocks spout. As described above, in the soft cleaning using the soft water discharge hole having a low water discharge speed, the washing feeling received from the water discharge is made at least softer by the lower water discharge speed than in the case of the normal butt cleaning at the bottom water discharge hole. Note that the bidet water discharge hole and the soft water discharge hole are not limited to a single hole as in the present embodiment, and a plurality of small-diameter fine holes are arranged to form a bidet water discharge hole and a soft water discharge hole as a whole. You can also. In this case, if the total area of the water discharge holes, which is the sum of the areas of the plurality of pores, is equal to or more than the area of the bottom water discharge holes, the water discharge becomes softer as a whole of the pores than in the case of the bottom cleaning.

Next, taking the bidet movable body NH1-11 as an example, how water is washed from the bidet discharge holes NH1-10 of the movable body will be described. FIG. 21 shows an electromagnetic coil NH1-33 when driving the bidet movable body NH1-11.
FIGS. 22A to 22C are explanatory diagrams for explaining the states of excitation of a to 33c.
FIG. 23 is an explanatory view schematically illustrating the state of the wash water spouting from the bidet spout NH1-10, FIG. 23 is an explanatory view schematically illustrating the instantaneous state of the wash water spouting, and FIG. It is another explanatory drawing for demonstrating the aspect of excitation of NH1-33a-33c.

The electronic control unit CT1-1 generates a pulse signal (transistor ON signal) and sequentially applies the pulse signal to the bases of the transistors Tr4 to Tr6 corresponding to the electromagnetic coils NH1-33a to 33c. I do. Therefore, the electromagnetic coils NH1-33a to 33c turn ON / OFF the respective transistors in accordance with the pulse signal, and
As shown in FIG. By such repeated excitation of each electromagnetic coil, the bidet movable body NH1-
The eleven magnetic action parts NH1-18a to 18c exert an attractive force by coil excitation (hereinafter, this force is referred to as a coil action force).
Is repeatedly and sequentially received. Therefore, this movable body is shown in FIG.
As shown in (2), the coil is inclined in accordance with the magnetic acting portion that has received the coil acting force, and the inclined portion is shifted along the excitation direction of the electromagnetic coil. As a result, the bidet spout NH1-10
Is tilted together with the movable body at the water discharge hole swing angle α (see FIG. 16), and swings and rotates in accordance with the tilt position transition of the movable body while maintaining the tilted posture. Thus, when the cleaning water is supplied to the movable body as described above, the cleaning water is discharged in the following water discharge form.

Since the spouting hole of the washing water is inclined at the spout angle α, the spouting water from the spouting hole is schematically represented as a water column, as shown in FIG.
Is inclined at the above-described water discharge hole swing angle α. In addition, since the water discharge hole is oscillatingly rotated, the schematic water discharge column RT moves in accordance with the swing rotation of the water discharge hole with the water discharge hole swing angle α, and the model water discharge water column continues one after another. Therefore, the wash water is discharged in a water discharge form such as a conical shape as illustrated in which the schematic water discharge water columns RT are arranged (hereinafter, this water discharge form is referred to as a pseudo-conical water discharge form). In addition, the swing rotation of the water discharge hole, that is, the movement (scanning) of the schematic water discharge column R is based on only the excitation (specifically, the sequential excitation) of the electromagnetic coil and is not affected by the flow rate of the cleaning water at all. Independent from. And since the model water discharge column R is a result of water discharge of the washing water from the water discharge hole, the water discharge direction of the model water discharge column R moving as described above is in relation to the illustrated center line or incorporates a movable body. It is three-dimensionally deflected with the angle of the water discharge hole swing angle α with respect to the nozzle. Therefore,
Each of the above-described electromagnetic coils and the movable body functions as “water discharge deflection means” in the present invention. At this time, the water discharge hole swing angle α is variously set and adjusted as described later.

Further, when this state is instantaneously captured, it can be simulated that the washing water is spirally discharged on the side walls of the cones defined by the respective discharge hole swing angles α as shown in FIG. When the washing water is discharged in such a mode, the movable body does not rotate because the movable body is fixed at the periphery of the flange. That is, only the water discharge hole is pivotally rotated at the water discharge hole swing angle α without causing the movable body to rotate. In addition, the movable body does not cause the swing rotation but only causes the tilt position transition.However, for the sake of convenience, the movable body tilt position transition operation accompanying the swing rotation of the water discharge hole is described as a pseudo swing of the movable body. It is called rotation.

The tail water discharge hole NH1-7 which swings and rotates at the water discharge hole swing angle α inclines with respect to the head water discharge hole NH1-46 below the head. Then, in such a positional relationship, the washing water is supplied from the bottom water discharge hole in the head to the bottom water discharge hole NH1-7 of the movable body. In this case, since the lower end of the bottom water discharge hole of the movable body is a large-diameter water discharge guide hole NH1-24, the washing water from the rear water discharge hole in the head is guided by the water discharge guide hole without any trouble. Water is spouted from the ass spout.

In the present embodiment, when exciting each electromagnetic coil, the duty cycle (t / T) when the pulse signal generation cycle (pulse cycle) is represented by T and the ON time of the pulse signal is represented by t is described. Variable control. By this duty ratio control, the coil acting force received by the magnetic acting portions NH1-18a to 18c of the movable body, that is, the water discharge hole swing angle α can be increased or decreased as follows. For example, as shown in FIG. 21A, the excitation period Tc (= Tc1) and the pulse period T (= T1) of each electromagnetic coil are fixed, and the pulse ON time t is set to t1.
(Duty ratio: t1 / T1) and the pulse ON time t is set to t2 (t2 <t1, duty ratio: t)
2 / T1), the water discharge hole swing angle α can be increased in the control period A and decreased in the control period B according to the duty ratio. For this reason, as shown in FIG. 22, the range in which the wash water spouted in the above-described pseudo-conical spout form is spouted, in other words, the washing area is widened based on the large spout angle α in the control period A as shown in FIG. The cleaning area AS can be obtained. In the control period B, a smaller cleaning area BS can be obtained. That is, in the present embodiment, through the variable control of the duty ratio, the water discharge hole swing angle α, that is, the cleaning area can be controlled to be large and small. In this case, the excitation order of the electromagnetic coil is changed to the electromagnetic coil N
From the order of H1-33a → 33b → 33c → 33a..., The electromagnetic coils NH1-33a → 33c → 33b → 33
.. can be reversed.

In this embodiment, the excitation cycle T of each electromagnetic coil
c is variably controlled. For example, as shown in FIG. 21B, the duty ratio is set constant in the control periods C and D ((t3 / T2) = (t4 / T3), t3 ≠ t4, T2
{T3), the excitation cycle Tc of each electromagnetic coil can be changed in each control period (Tc1> Tc2). This excitation cycle Tc is represented by a schematic individual water discharge column R shown in FIG.
T determines the interval at which the human body is stimulated by hitting the part to be cleaned (local part of the human body).

Generally, when a stimulus that can be sensed (stimulation by the schematic water discharge column RT in this embodiment) is repeatedly applied to the same portion of the human epidermis, if the repetition interval is long and the repetition frequency is low, the person repeats the repetition. The sensed stimulus is sensed each time as a vibration stimulus. On the other hand, if the repetition interval is short and the repetition frequency is high, a person cannot perceive this intentionally repeated stimulus as a vibration stimulus but perceives it as a continuous stimulus. In other words, there is a dead band frequency that cannot be sensed as a vibration stimulus for a repetitive stimulus to the human epidermis. Here, in the washing of the local area and its surroundings, it is assumed that the magnitude of the flow rate or flow velocity of the washing water is repeatedly spouted (hereinafter, referred to as repeated spouting) when viewed from the human skin to be stimulated, and the magnitude of the stimulation from the spouting water is repeated. This repeated spouting appears as a vibratory stimulus on the epidermis of the washed area. If this is a repetition frequency of about 5 Hz or more, the perception cannot follow the vibration based on this intentional repeated water discharge. For this reason, it becomes impossible to be conscious of the water discharge mode of intentional repeated water discharge, and discomfort due to unnecessary vibration is reduced. As the repetition frequency of the repetitive water discharge increases, it becomes more difficult for the perception to follow the vibration based on the intentional repetition of the water discharge.
The majority of people with normal perception have almost no perception of vibration due to intentional repeated water discharge. Therefore, it is difficult to recognize a water discharge mode that is intentional repeated water discharge, and discomfort due to unnecessary vibration is further reduced. Further, at a repetition frequency of about 15 Hz or more, even the average part of the human epidermis exceeds the vibration recognition frequency, so that most people having ordinary perception do not feel discomfort. Furthermore, at a repetition frequency of about 20 Hz or more, even a sensitive part of the human epidermis exceeds the vibration recognition frequency, so that a large number of people with normal perception can surely feel continuous and good washing feeling. it can. In addition, at a repetition frequency of about 30 Hz or more, even in a sensitive part where nerves of the human epidermis are particularly concentrated, the frequency exceeds the vibration recognition frequency. be able to. Then, the repetition frequency is made to coincide with the commercial frequency (50 Hz in the commercial frequency 50 Hz area, commercial frequency 6).
(60 Hz in a 0 Hz area), which also has the effect of facilitating driving. As the frequency is increased in this manner, the washing can be performed while feeling the continuous washing feeling more reliably, and it is possible to sufficiently cope with a user who desires a softer washing feeling.

From the viewpoint of the dead band frequency, in this embodiment, the excitation cycle Tc of each electromagnetic coil is set to its excitation frequency f
(= 1 / Tc) is variably controlled so as to be in a range of about 5 Hz or more, so that a stimulus to a local human body by the schematic water discharge column RT is sensed as a continuous stimulus. That is, the cleaning water is only intermittently discharged at a certain point in the human body part (for example, the cleaning point SP1 shown in FIG. 22) at the excitation cycle Tc.
Makes you feel that you are receiving continuous flushing. Since this occurs at each of the washing water spouting points, the user can be given a washing feeling as if the washing water is uniformly and continuously received over the washing area. In this case, through the control of the electromagnetic coil described above, although the schematic water discharge column RT changes its water discharge direction and water discharge position as shown in FIGS. 22 and 23, the change is stimulated as described above. Thus, the electronic control device that controls the electromagnetic coil functions as the “fluctuation inducing means” in the present invention. And
As described above, giving a feeling of washing as if the washing water is uniformly and continuously discharged over the washing area means the following.

In order to provide the above-described continuous washing feeling over a certain range of washing area, the existing washing nozzle having the washing water spouting hole fixed has a conical spread of the spouted washing water itself. I need. Therefore, it is necessary to supply a considerable amount of cleaning water at all times.
Wash water was spouted at a flow rate of about cc / min. In such water spouting, the washing water is constantly spouted at all the washing water spouting points. However, in the local cleaning device of the present embodiment, the cleaning nozzle WN1-1 is used.
In order to give a continuous washing feeling as in the case of the existing one by the above-mentioned pseudo-conical water discharge form, in fact, only intermittent water discharge at the excitation frequency f is actually performed. That is, in each of the washing water spouting points, in the present embodiment, the spouting of the washing water is intermittently thinned out, so that the amount of the washing water can be reduced. Therefore, in the present embodiment, the flow rate of the cleaning water is set to about 500 cc / min by the constant flow valve as described above, and it is only necessary to discharge the cleaning water at the maximum flow rate.

As described above, in order to prevent the water from being detected as intermittent water discharge, the excitation frequency may be set to about 5 Hz or more. In the present embodiment, the excitation frequency is set to about 10 to 10 Hz.
The frequency was set to 60 Hz so that a feeling of continuous washing water spouting could be obtained more reliably.

Even if the excitation frequency f is set to the above-mentioned dead band frequency, it can be said that the sense of continuous spouting received from the continuous spouting of the wash water tends to be weaker as the excitation frequency f is lower.
Therefore, the excitation frequency f can be lowered within the above range to provide a good stimulating feeling to the user's cleaning feeling, and the excitation frequency f can be increased to give a soft or mild stimulating feeling to the cleaning feeling.

Further, under the condition that the uniform sense of continuous spouting of the washing water over the washing area is given as described above, the washing area can be controlled to be large and small as described above. Therefore, when the washing area is narrowed and the user receives the washing water spouting in the narrow washing area, the washing water spouting point is concentrated and the washing area is widened to spread the washing water spouting point. Thus, a different feeling of washing can be given to the user who has received the flushing water. For example, since the pain point distribution is more dense around the anus than in the center of the anus, in the ass washing, a soft feeling of washing is given when the spouting point is concentrated, and hard when the spouting point is diffused. It can give a feeling of washing. Although the cleaning feeling can be changed by controlling the cleaning area in a wide or narrow manner, a case where the cleaning area is intentionally variably controlled through variable control of the duty ratio will be described later.

In FIG. 21, the case where one of the duty ratio and the excitation frequency is fixed and the other is controlled has been described. However, in this embodiment, as shown in FIG. 24, the excitation frequency f can be controlled to increase or decrease according to the duty ratio. In FIG. 24A, a soft or mild stimulus can be given by increasing the excitation frequency f while increasing the duty ratio to increase the cleaning area. In other words, this is good when a large cleaning area is to be cleaned with a more continuous cleaning feeling. Conversely, while reducing the duty ratio to reduce the cleaning area, the excitation frequency f can be lowered to reduce the continuous sensation of water discharge and provide a good stimulus sensation.

On the other hand, in FIG. 24B, the excitation frequency f is lowered while increasing the duty ratio to increase the cleaning area. Therefore, in the case of ass cleaning, the excitation frequency f is lowered while giving a hard washing feeling due to a large washing area, and the sense of continuous water discharge is weakened. be able to. In addition, since the high excitation frequency f does not give an intermittent stimulus while giving a soft sensation of washing with a small washing area, the soft sensation of washing can be made more continuous. That is, by controlling as shown in FIG. 24, it is possible to further diversify the feeling of cleaning. Note that the excitation frequency f can be increased or decreased stepwise instead of linearly increasing or decreasing as shown in FIG.

Even if the excitation cycle Tc of each electromagnetic coil is changed with the duty ratio kept constant as shown in FIG. 21B, the water discharge hole deflection angle α (cleaning area) is varied as follows. Can be set. If the excitation cycle Tc is shortened, the time during which the above-mentioned coil acting force acts on the magnetic acting portion is shortened, so that the water discharge hole deflection angle α is reduced and the cleaning area is reduced.
Further, if the excitation cycle Tc is made longer, the operating time of the coil acting force becomes longer, so that the water discharge hole swing angle α becomes larger and the cleaning area becomes larger. Then, even in a situation where the excitation cycle Tc is fixed with a small value, if the duty ratio Dt is increased, the water discharge hole swing angle α can be increased and the cleaning area can be increased as described above. Similarly, in a situation in which the excitation cycle Tc is fixed while being large, the duty ratio Dt can be reduced to reduce the water discharge hole swing angle α and the cleaning area. In other words, even if the excitation cycle Tc is fixed at the above value so that the dead band frequency becomes the above-mentioned value, the cleaning area can be set to be wide or narrow by the variable control of the duty ratio.

In this embodiment, the coil excitation control is performed such that all the electromagnetic coils are kept in the non-excited state or all the electromagnetic coils are excited at the same time under the continuation of the washing water spouting. You can do it too. In this case, when all the electromagnetic coils are de-energized, the cleaning water is discharged from the water discharging hole of the movable member in a free state to one point with air mixing. On the other hand, when all the electromagnetic coils are excited at the same time, the wash water is discharged from the water discharge hole of the movable body adsorbed to the magnetic force generator at one point without air mixing. The coil excitation control for causing such one-point concentrated water discharge is not performed continuously, but is performed in combination with the above-described control of the cleaning area through the duty ratio control. In other words, when the excitation of each electromagnetic coil is sequentially controlled at a duty ratio that results in a certain cleaning area, the simultaneous excitation of all the electromagnetic coils is intermittently incorporated and executed, and the execution cycle of the simultaneous excitation of all the electromagnetic coils is set as described above. Excitation frequency f
Is a cycle that satisfies By doing so, the human body local range determined by the cleaning area and one point within the range can be washed while the user has a sense of continuous spouting of the washing water.

F1 / Washing / Drying Operation Routine Next, the washing / drying operation performed by the local cleaning apparatus of the present embodiment having the above-described configuration will be described. FIG. 25 is a flowchart showing a butt and bidet cleaning and drying operation routine executed by the electronic control unit CT1-1, and FIG. It is a flowchart of FIG. FIG.
FIG. 2 is an explanatory view schematically showing a state of cleaning water spouting in nozzle pre-washing prior to the cleaning water spouting at the time of local cleaning, FIG.
8 is a flowchart of the main cleaning routine showing details of the main cleaning operation processing in the cleaning / drying operation routine, FIG.
FIG. 8 is an explanatory diagram for describing the processing content of the main cleaning routine and the processing content of the operation stop routine.

The washing / drying operation routine shown in FIG. 25 is executed when one of the washing buttons (bottom, soft, bidet buttons) or the drying button is operated. In this cleaning / drying operation routine, FIG.
As shown in the flowchart of FIG.
By scanning S10, it is determined whether or not the user is seated on the toilet seat (step S100). If it is determined that it is not in the seated state, the local cleaning device is not used, so that the subsequent processing is unnecessary and this routine is terminated without performing any processing. If the seat is in a seated state, since the local cleaning device is in use, either the cleaning button (the button for the bottom, the soft or the bidet) or the drying button is used to perform the cleaning operation or the drying operation. It is determined whether the operation has been performed during execution of the routine (step S105). In the following description, the remote control device RC1-1 is used.
It is assumed that each of the buttons has been operated.

In the above step S105, the drying button SW
If it is determined that z has been operated, the drying operation inhibition flag FKsto stored at a predetermined address in the backup RAM is determined.
The state of p is read, and it is determined whether or not FKstop = 1 (step S110). The drying operation prohibition flag FKstop indicates that a power supply abnormality has occurred in the drying unit KK1-1 (see FIG. 5) such as a drying heater for local drying or a fan motor. Further, if FSstop = 1, it indicates that cleaning or the like should not be executed for a coil abnormality (drying is not related). Then, the drying operation prohibition flag FK
In the stop, a value 1 or a value “0” is set in a drying failure detection routine and a recovery routine (not shown). Therefore, if an affirmative determination is made in step S110, this routine ends without performing any processing. If a negative determination is made in step S110, the above-described power supply control to the drying unit KK1-1 (step S115) is performed irrespective of the prohibition state of the cleaning operation described later, and this routine ends. By this step S115, warm air is blown toward the local area, and local drying is performed. At this time, the power supply to the drying unit is controlled so that the hot air temperature becomes the drying temperature set by the drying knob of the auxiliary operation unit KS1-9 (see FIG. 3). The power supply to the drying unit is stopped in an operation stop routine described later.

On the other hand, if it is determined in step S105 that one of the buttocks, soft, and bidet washing buttons has been operated, the state of the washing operation inhibition flag FSstop stored at a predetermined address in the backup RAM is read, and FSstop = 1. Is determined (Step S
120). The cleaning operation prohibition flag FSstop is determined by the coils NH1-30a to 30c and 31a to 31c of the electromagnetic coils in the swinging coil groups for the hips and the bidet (FIG. 1).
9, FIG. 20) shows that coil energization abnormality such as disconnection or contact failure has occurred. That is, FSstop = 1 means that the cleaning operation should not be performed for the coil abnormality, but the cleaning operation should be prohibited. The cleaning operation prohibition flag FSstop is set to a value of 1 in a swing detection routine to be described later and to a value of 0 (zero) in an abnormality recovery routine. Therefore, step S
If an affirmative determination is made in 120, this routine ends without performing any processing.

If a negative determination is made in step S120,
Prior to the cleaning water spouting for the local cleaning, nozzle pre-cleaning for cleaning the nozzle head NH1-1 (see FIGS. 5, 6, and 12) is executed (step S130).

As shown in the flow chart of FIG. 26, in the pre-nozzle cleaning routine, the solenoid valve WP1-10 of the water inlet side valve unit WP1-1 shown in FIG. 4 is controlled to open (step S131). Next, the switching control of the switching valve WP1-15 to the flow path for functional water is performed, and the flow control pump WP1-14 is controlled.
Of the function water discharge flow rate (step S1)
32). Thereby, functional water (free chlorine solution) is discharged toward the nozzle head at the standby position HP shown in FIG. 8, and the head is sterilized and washed. As described above, in the functional water unit, since the functional water has already been generated in the tank at each of the above timings, the generated functional water is discharged by the tank storage amount (about 50 cc).

Next, in order to stop the functional water spouting, the switching control of the switching valve WP1-15 from the functional water flow path to the buttocks cleaning flow path and the nozzle cleaning flow rate of the flow control pump WP1-14 are performed. Is performed (step S133). Thus, in a state where the nozzle head is at the standby position HP shown in FIG. 8, the cleaning water is discharged from the tail water discharge port NH1-7 of the nozzle head toward the chamber NS1-14. At this time, since the above-described coil excitation is not performed, the ass movable body NH
1-9 is a free state in which no swing rotation occurs. Therefore, as shown in FIG.
The washing water is spouted at one point. In addition, since the bottom water discharge hole NH1-7 has a small diameter, the water discharge speed is high. For this reason, the cleaning water rebounds vigorously in the chamber, and the nozzle head is cleaned with the repelling cleaning water.
This makes it possible to preferably clean the nozzle head, more specifically, the water discharge holes of the nozzle head and the periphery thereof. In addition, the functional water (free chlorine solution) applied to the nozzle head in step S132 can be washed away. When the functional water generation unit is of a type in which the water passage is sandwiched between the chlorine generation electrodes, the energization control to the chlorine generation electrodes WP1-17 (see FIG. 9) for generating the functional water is performed in step S132. May be executed, and the energization of the chlorine generating electrode may be stopped in the subsequent step S133.

When the steps S132 and S133 in the pre-nozzle cleaning routine are executed, the movable buttocks NH1-
9. It is also possible to simultaneously and continuously excite all the electromagnetic coils of the bidet movable body NH1-11. In this way, the buttocks movable body NH1-9 is added to the magnetic force generator NH1-26.
And the bidet movable body NH1-11 is adsorbed, and the gap between the lower ends of both movable bodies and the magnetic force generator NH1-26 is closed.
Corrosion acceleration of the magnetic driving bodies NH1-18 and the coil iron cores NH1-35 due to the scattering of functional water can be suppressed.

Further, when step S133 is executed, only the front electromagnetic coil NH1-32a of the buttocks movable body NH1-9 can be continuously excited. In this way, the washing water can be concentrated and discharged at one point in a state where the buttocks movable body (butt water discharging hole) is inclined toward the bidet movable body NH1-11. Therefore, even though the water is discharged from the bottom water discharge hole, it is possible to surely splash back and apply the cleaning water to the soft water discharge hole, the bidet water discharge hole, and the vicinity thereof. For this reason, each water discharge hole and its periphery can be reliably washed. In addition, the bidet spout hole and its surroundings, which require the user to have a sense of cleanliness for the purpose of bidet washing, can be washed with high washing ability, and the sense of cleanliness can be enhanced.

Note that the cleaning water spouting at the time of the nozzle pre-washing is performed by the soft spouting hole NH1-of the buttocks movable body NH1-9.
8 and bidet discharge hole NH1-1 of bidet movable body NH1-11
It may be performed from 0. At this time, when flush water is discharged from the soft water discharge hole NH1-8, the excitation of the front electromagnetic coil NH1-32a and the simultaneous excitation of the two rear electromagnetic coils NH1-32b and 32c are repeated. The washing water may be discharged while swinging the buttocks movable body (soft water discharging hole) in the front-rear direction. By doing so, the water can be surely washed by splashing the cleaning water to the water discharge holes before and after the water discharge holes and the periphery thereof.
When the cleaning water is spouted at the time of pre-nozzle cleaning at the bidet spout NH1-10, it is the same as the tail spout.

Further, at the time of execution of the above-mentioned step S133, the buttocks movable body NH1-9 can be pseudo-oscillatingly rotated at a predetermined water discharge hole swing angle α. That is, a pulse signal for sequentially exciting each electromagnetic coil is output based on the duty ratio Dt that determines the water discharge hole swing angle α and the excitation cycle Tc of each electromagnetic coil (see FIG. 21). As a result, the buttocks movable body NH1-9 performs a pseudo swing rotation at the water discharge hole swing angle α and the excitation frequency f (= 1 / Tc), and the buttocks water discharge holes N
H1-7 also swings and rotates with this. Therefore, FIG.
As shown in (b), the flush water is spouted from the hip water spout NH1-7 in a pseudo-conical water spout form shown in FIG. 22 and FIG. By doing so, the range of spouting of the washing water in the chamber NS1-14 is expanded, so that not only the buttocks spouting holes but also the soft spouting holes, the bidet spouting holes and the periphery thereof can be reliably washed with the washing water. In this case, since the washing water is discharged from the chamber and not the human skin, the excitation frequency f (= 1 / Tc) does not need to be set to the above-mentioned dead band frequency, and may be determined as appropriate.

The processing in step S133 is performed for a predetermined time.
For example, after continuing for about 1 second, stop control of the flow regulating pump (zero flow) and closing control of the solenoid valve are sequentially performed (steps S134-135), and the process proceeds to step S140 in FIG.

Following the above-described nozzle pre-cleaning, the nozzle drive motor NS1-4 is controlled to rotate in the normal direction, and the cleaning nozzle WN1-1 is moved to the cleaning position corresponding to the cleaning button (butt, soft, bidet). It is advanced from the standby position HP in the main body (step S140; see FIG. 7). The cleaning nozzle WN1-1 advances to the hip cleaning position AWP if the cleaning button is a soft bottom and the cleaning button, and advances to the bidet cleaning position VWP if the bidet cleaning button.

When the advancement of the cleaning nozzle to the cleaning position is completed, the following main cleaning operation corresponding to the cleaning button (butt, soft, bidet) is executed (step S150).
This routine ends. This main cleaning operation is stopped by an operation stop routine described later.

In this main cleaning operation, the movable body to be used differs depending on the cleaning button. Therefore, in the following description, the butt cleaning will be described as an example, and the soft cleaning and the bidet cleaning will be described only on the different points. I do.

As shown in the flowchart of FIG. 28, in the present cleaning routine, the solenoid valves WP1-10 are controlled to open so as to start the supply of the cleaning water once stopped during the nozzle advance to the buttocks cleaning position AWP. (Step S151). Next, the switching valve WP1-15 is switched to the buttocks cleaning flow path, and the flow control pump WP1-14 is driven to a predetermined weak water discharge flow rate (for example, flow rate level 1) (step S152). . As a result, the washing water having the above-described weak water discharge flow rate is discharged from the tail water discharge hole NH1-7 of the nozzle head toward the buttocks. The processing in step S152 in the case of soft cleaning and bidet cleaning is as described above, except that the flow path is switched by the switching valve to the soft cleaning flow path or the bidet cleaning flow path.

Thus, the flow rate of the weak water discharge at the time of the initial water discharge is determined as follows. Now, it is assumed that the flow rate can be adjusted to other levels, for example, levels 1 to 7 in the adjustable range (for example, 500 cc / min) by the flow regulating pump. In the above step S152, the ass movable body N
The washing water is discharged in a state where H1-9 is not movable (non-rotating rotation). Since the water spouting at the above-described excitation frequency f due to the swinging rotation does not occur, the water spouting water has a one-point concentrated water spouting form, and the water spouting speed is large because the bottom spout hole NH1-7 has a small diameter. . Therefore, step S
If the flow rate of the weak water discharge at 152 is, for example, the flow rate of the lowest level 1 in the above range, the user does not need to give a special feeling of discomfort or discomfort even if the water discharge is performed at a high speed and concentrated at one point. Note that the washing water spouting in step S152 is as follows.
This is only a short period (less than about 0.5 seconds) at the beginning of the main cleaning. Also from this, the user does not need to feel any particular discomfort or discomfort. Hereinafter, a case will be described in which the flow rate of the weakly spouted water to be initially spouted is set to the flow rate level 1.

Following the washing water spouting at the weak water spouting flow rate (flow rate level 1) in the above step S142 (see FIG. 29), the habituation of the buttocks movable body NH1-9 during the pseudo swing rotation described above is performed. The buttocks movable body NH1-9 is initially driven for driving and swing abnormality detection (step S).
143). The swing abnormality detection will be described later in detail.

In this initial drive processing, first, the duty ratio Dt that determines the water discharge hole swing angle α is set to an initial value α0 such that the water discharge hole swing angle α becomes the initial value α0 that allows the running-in operation of the movable body and the detection of a swing abnormality. The duty ratio is set to Dt0. Since the initial duty ratio Dt0 is stored in the backup RAM, it is set by reading the value. Then, based on the initial duty ratio Dt0 and the excitation cycle Tc of each electromagnetic coil, a pulse signal for sequentially exciting each electromagnetic coil is output (see FIG. 21). As a result, the buttocks movable body NH1-9 quasi-oscillately rotates at the water discharge hole swing angle α0 and the excitation frequency f (= 1 / Tc), and the buttocks water discharge holes N
H1-7 also swings and rotates with this. Therefore, as shown in FIG. 29, the wash water having the weak water discharge flow rate (flow level 1) set in step S142 is discharged in the pseudo-conical water discharge form shown in FIGS. 22 and 23. It should be noted that even in this initial drive, only a short period (about 0.5 seconds or less) before the main cleaning drive in the next step is performed. The user does not have to feel uncomfortable or uncomfortable.

In this initial driving process, the water discharge hole deflection angle α
0 is only required to be able to detect swing abnormality and the like, and the water discharge flow rate at this time is also a weak water discharge flow rate (flow level 1).
There is no need to increase it carelessly. Therefore, a low value (for example, a value of about 10% of αmax or the minimum water discharge hole deflection angle αmi) in the range of the water discharge hole deflection angle α that can be adjusted in the present embodiment.
n). Further, the excitation frequency f (= 1 / Tc) is set to the above-mentioned predetermined value of the dead band frequency. Hereinafter, a case will be described in which the water discharge swing angle α0 at which water is initially discharged is set to αmin.

Next, following the above-described initial drive processing,
The main body is driven for main cleaning (step S154). In the main cleaning driving process, the butt water discharge holes NH1-7 are oscillated and rotated in the practical range through the butt movable body NH1-9 to perform cleaning water discharge, and the pseudo cone shown in FIG. 22 and FIG. This is for actually performing local cleaning in the form of a spout. In the main cleaning drive process, first, the duty ratio Dt that determines the water discharge hole swing angle α is changed to an appropriate duty ratio Dt1 corresponding to a predetermined value of the adjustable water discharge hole swing angle α. Since the proper duty ratio Dt1 is stored in the backup RAM, it is set by reading the value. This proper duty ratio Dt1 is the initial duty ratio D in the actual local cleaning by the main cleaning driving process.
Since it is t, it is set to a value corresponding to a predetermined value (for example, an intermediate value αmid) in the range of the water discharge hole swing angle α that can be adjusted in this embodiment (see FIG. 29). Hereinafter, a case will be described in which the predetermined water discharge swing angle α at the start of the main cleaning is αmid.

The proper duty ratio D thus read
t1 is written and stored in the RAM in order to deal with updating / setting in the spot-wide cleaning routine described later. If the duty ratio Dt is not updated / set in the spot / wide cleaning routine, the appropriate duty ratio Dt1 remains stored in the RAM. If the duty ratio Dt is newly updated / set in the spot / wide cleaning routine, , The appropriate duty ratio Dt1 of the RAM is rewritten with this new updated / set value. Therefore, after updating and setting of the duty ratio Dt during the continuation of the cleaning, the movable body and the tail water discharge hole are swung and rotated based on the rewritten duty ratio Dt.

The rewritten duty ratio Dt and the rewritten non-rewritten proper duty ratio Dt1 are reset by the OFF signal of the seating sensor when the user rises from the toilet seat. .
Thus, when the user repeats the cleaning operation while sitting, the updated and set duty ratio Dt is used in the main cleaning driving process of the second and subsequent steps in step S154 instead of the appropriate duty ratio Dt1. be able to. Therefore, in the case of repeated use, the duty ratio Dt
(I.e., the water discharge hole swing angle α) is the same as the previous time, so that a feeling of strangeness at the time of repeated use can be eliminated. In the cleaning operation performed again after the user leaves the toilet seat, the appropriate duty ratio Dt1 is used as described above.

When the proper duty ratio Dt1 is set in this way, a new pulse signal for sequentially exciting each electromagnetic coil is generated based on this proper duty ratio Dt1 and the excitation cycle Tc of each electromagnetic coil. Output (Fig. 21
reference). Thereby, under the flush water supply of the weak water discharge flow rate (flow rate level 1), the buttocks movable body NH1-9 quasi-oscillates and rotates at the water discharge hole swing angle αmid and the excitation frequency f (= 1 / Tc), The tail water outlet NH1-7 also swings and rotates with this.

Then, following this pulse signal output,
The flow control pump WP1-14 is driven so as to have an appropriate water discharge flow rate (for example, flow rate level 4) in the adjustable range shown in FIG. 29 (step S155). This proper water discharge flow rate is set and stored in the same manner as the above-described proper duty ratio Dt1. Hereinafter, a case will be described in which the appropriate water discharge flow rate at the start of the main cleaning is set to flow rate level 4.

By the pulse signal output and the supply of the proper water discharge flow rate, at the start of cleaning, the cleaning water having the proper water discharge flow rate (flow rate level 4) is in an appropriate state (water discharge hole swing angle αmi).
d, water is spouted from the hip water spout NH1-7 that swings and rotates at the excitation frequency f (= 1 / Tc). After that, the user changes the water pressure or the swing angle α
If the (washing area) is changed, the flush water of the changed water force swings and rotates at the changed spout angle α.
Water is discharged from 1-7. The washing water at this time is ejected toward the human body part in the form of a pseudo-conical spout shown in FIGS. 22 and 23, and the excitation frequency f that causes this spouting is included in the dead band frequency. Therefore, the user:
An unprecedented excellent effect of giving a continuous washing feeling of the washing water and giving no uncomfortable feeling or discomfort can be achieved. Further, as described above, the cleaning water is supplied in the excitation cycle T
By making the water oscillate and discharge at c, the effectiveness of water saving can be enhanced.

Further, the flow rate of the washing water can be reduced by improving the efficiency of water saving, and in some cases, the flow rate can be reduced to about half of the conventional flow rate. Therefore, the tank capacity of the heat exchange unit TH1-1 can be reduced. In addition, since it is only necessary to heat the cleaning water with a heater in a tank having a small flow rate and a small capacity, it is possible to further promote power saving and downsizing of the heater TH1-2.

In the quasi-oscillating rotation of the buttocks movable body NH1-9 in the cleaning driving process, the cleaning water is supplied in advance with a weak water discharge flow rate (flow level 1) in the initial driving process immediately before. . Therefore, the quasi-oscillating rotation of the movable body is started in a state in which the pressure of the supply water is set at the weak water discharge flow rate (flow level 1). For this reason, the pseudo-oscillating rotation of the movable body in the no-load state is not caused, so that careless force is applied.
Flange NH1-2 of elastic material such as rubber or elastomer
Never multiply by zero. As a result, inadvertent damage to the flange portion can be avoided, and the movable body can be appropriately pseudo-swing-rotated from the beginning, which is preferable.

As shown in FIG. 29, the duty ratio Dt is changed from the initial set value Dt0 to the appropriate value Dt1 so that the water discharge hole swing angle α gradually increases from the initial value α0 to the intermediate value αmid, and the water discharge flow rate is increased. Initial value (flow level 1)
The water discharge flow rate is changed and set so as to gradually increase to the proper water discharge flow rate (flow rate level 4). Therefore, there are the following advantages. First of all, at the beginning of the first cleaning that receives the flush water spout, unintended multiple flow of the flush water is not received over an unintended wide cleaning area, so that uncomfortable feeling can be avoided. In addition, since the movable body is not suddenly quasi-oscillated at a large water discharge hole swing angle α, no excessive force is applied to the supporting portion (flange connecting portion) and the coil of the movable body, and the movable body in step S153 is not rotated. In conjunction with the initial drive, it is possible to reliably avoid inadvertent damage due to the running-in operation.

Steps S153 to S153 for Soft Cleaning
The process at 154 is not different from hip cleaning.
In the case of bidet cleaning, the apparatus control is performed as described above except that the movable body is the bidet movable body NH1-11.
The proper duty ratio Dt1 at 154 can be different from that of the bottom cleaning. That is, at the time of bidet cleaning, the appropriate duty ratio Dt1 is set to the water discharge hole swing angle α at the time of the hip cleaning.
(= Αmid) is set to be larger than the appropriate duty ratio Dt1, and the water discharge hole swing angle α at the time of bidet cleaning is made larger than the water discharge hole swing angle α (= αmid) of the tail cleaning. As a result, at the time of washing the buttocks and the bidet, step S154-1 is performed.
The cleaning area of the cleaning water discharged by the cleaning water 55 can have a wide or narrow difference. More specifically, the cleaning area at the time of ass cleaning can be set to the cleaning area BS shown in FIG. 22, and the cleaning area at the time of bidet cleaning can be set to a larger cleaning area AS. As a result, when cleaning the buttocks and bidet, the above-mentioned water-saving effect is ensured together, and at the time of bidet cleaning, a large amount of washing water is spouted by a large amount of washing water by a large amount of washing water. Can give a feeling.

Note that the above-mentioned step S154- with an appropriate duty ratio Dt1 and an appropriate water discharge flow rate (flow rate level 4) is performed.
After the execution of 155, the water strength setting buttons SWhu, SW
In response to the operation of each of the hd and spot-wide setting buttons (see FIG. 2), the water discharge flow rate (flow rate level) and the cleaning area (water discharge hole swing angle α, duty ratio Dt) are variously changed.
Then, at the changed flow rate and cleaning area (water discharge hole swing angle α), the above-described water discharge in the form of a pseudo-conical water discharge is performed (see FIG. 29). The water discharge flow rate (flow rate level) and the duty ratio Dt thus set are stored in the RAM and reset via the OFF signal of the seating sensor as described above.

G1 / operation stop routine: Next, an operation stop routine executed by the local cleaning apparatus of the present embodiment will be described. FIG. 30 is a flowchart showing the operation stop routine.

The operation stop routine shown in the flow chart of FIG. 30 is for stopping the cleaning operation and the drying operation performed in the above-described cleaning / drying operation routine, and is therefore executed at the following timing. . The first interrupt timing is at the time of operating the stop button SWa for stopping various operations of the main cleaning unit. The second interrupt timing is when the user moves away from the seat sensor, which is equivalent to leaving the toilet seat, since the subsequent washing and drying operations are unnecessary if the user leaves the toilet seat. The third interrupt timing is when the operation is switched from the cleaning operation to the drying operation or from the drying operation to the cleaning operation, and is when the drying button is operated during the cleaning operation and when the cleaning button is operated during the drying operation. When the operation stop routine is executed at these interrupt timings, first, as shown in FIG. 30, it is determined whether the current operation state of the apparatus is a cleaning operation or a drying operation (step S160). Here, when it is determined that the drying operation is being performed, the power supply to the drying unit is stopped (step S162), and this routine ends. The operation state of the apparatus is determined based on the operation state of the cleaning or drying button before the start of this routine.

On the other hand, if it is determined that the cleaning operation is being performed, the flow control pump WP1-14 is driven and controlled to zero flow (step S164), and thereafter, the solenoid valve WP1-10 is controlled to close (step S165). ). As a result, the supply of the washing water is cut off, and the washing water spouting that has been performed until then is stopped. In addition to this electromagnetic valve closing, the switching valve WP1-15 can be controlled to return to the origin position (for example, the buttocks passage switching position).

Subsequent to the stop of the washing water spouting, the output of the pulse signal (see FIG. 21) for making the washing water spouting into a pseudo-conical spouting form (see FIGS. 22 and 23) is stopped (step S1). S166) The movable body is stopped. As described above, since the swing rotation is stopped after the water discharge is stopped, the cleaning water is not discharged toward the human body local part when the movable body is stopped when the cleaning operation is stopped. Therefore, FIG.
Since one-point concentrated washing water as shown in (a) is not applied to the local area, there is no sense of discomfort or discomfort.

When the washing water discharge stops, the movable body stops. However, other control such as stopping the movable body based on a timer may be added. By providing a timer synchronized with the cleaning or independent of the cleaning, a safe operation of the movable body and each coil can be performed.

[0135] Following the stop of water discharge and the stop of swing,
The nozzle drive motor NS1-4 is controlled to rotate in the reverse direction, and the cleaning nozzle WN1-1 is retracted from each cleaning position to the standby position HP in the main body (step S168; see FIG. 7). After the nozzle is returned to the standby position HP, post-nozzle cleaning is performed to clean each water discharge hole and its surroundings, which has been used for the local cleaning, and furthermore, the nozzle head (step S169). This post-nozzle cleaning is performed in the same manner as the above-described pre-nozzle cleaning, that is, cleaning with functional water, and cleaning with bounce water that has been discharged from a water discharge hole. Note that the pre-nozzle cleaning and post-nozzle cleaning may be different in the processing content. For example, in the pre-nozzle cleaning, since the local cleaning is to be performed, the nozzle head is sterilized and cleaned by functional water spouting just before the local cleaning so as to give the user a sense of hygiene and cleanness of the nozzle head. However, functional water spouting may be omitted. The pre-nozzle cleaning and post-nozzle cleaning may be reversed. If sterilization cleaning is performed immediately after the bacteria adhere to the nozzle head, the sterilization effect is enhanced. it can. At the time of both washings, the one-point concentrated water discharge shown in FIG.
The conical water discharge shown in (b) can be used in combination. It is also possible to perform one-point concentrated water discharge in pre-nozzle cleaning, and to perform conical water discharge in post-nozzle cleaning. Further, the pre-nozzle cleaning and the post-nozzle cleaning can be reversed.

H1 / Move Cleaning Routine Next, a description will be given of a move cleaning routine executed by the local cleaning apparatus of this embodiment in association with the above-described local cleaning. FIG. 31 is a flowchart showing the move cleaning routine, and FIG.
FIG. 4 is an explanatory diagram for explaining a state of move cleaning.

The move cleaning routine shown in the flowchart of FIG. 31 is for discharging cleaning water while reciprocating the cleaning nozzle WN1-1 back and forth to give a wide range of cleaning feeling. The move cleaning routine is interrupted by the operation of the move setting buttons SWfa and SWfv (see FIG. 2) during the execution of the local cleaning of the hips and bidet.

As shown in FIG. 31, when the move cleaning routine is executed through the operation of the button, the nozzle drive motors NS1-4 are controlled to rotate forward and reverse, and the positions for cleaning the buttocks and bidets are controlled. Washing nozzle WN1-
1 is reciprocated back and forth (step S170). This reciprocating motion of the nozzle is continued until the move setting button is operated again to turn off the move cleaning (step S172). In this way, even while the nozzle is reciprocating back and forth, the main cleaning operation described above (step S1)
40) has been performed. Therefore, by simultaneous execution of the nozzle reciprocating motion and the flush water spouting in the pseudo-conical spouting mode (see FIGS. 22 and 23), the cleaning water spouting in the pseudo-conical spouting mode causes the nozzle movement as shown in FIG. It moves back and forth accordingly. For this reason, the local move cleaning is performed in such a manner that the cleaning water spouting in the form of a pseudo-conical water spouting continues over the reciprocating range of the nozzle. As a result, it is possible to create a new washing feeling that the local part is washed over an extremely wide range, and to give the user this new washing feeling.

If it is determined in step S172 that the move cleaning is to be stopped, the nozzle drive motor NS1-4 is rotationally controlled to return the cleaning nozzle WN1-1 to the butt or bidet cleaning position (step S174). This routine ends. When the stop button is operated, the operation stop routine of FIG. 30 is executed prior to the process of step S174, and the water supply is stopped and the nozzle is returned to the standby position.

I1 / Spot / Wide Cleaning Routine Next, a spot / wide cleaning routine executed by the local cleaning apparatus of this embodiment in conjunction with the above-described local cleaning will be described. FIG. 33 is a flowchart showing this spot-wide cleaning routine, and FIG. 34 is an explanatory diagram for explaining the state of spot-wide cleaning.

The spots shown in the flowchart of FIG.
In the wide cleaning routine, the cleaning area of the cleaning water spout is adapted to the user's request for the cleaning area of the human body part, thereby giving the user a feeling of satisfaction and irritation for cleaning. And
This spot / wide cleaning routine is performed during spot cleaning of the buttocks and the bidet while the spot setting button SWu is being executed.
a, SWuv and wide setting buttons SWva, SWvv
The interrupt is executed in accordance with the operation (see FIG. 2).

As shown in FIG. 33, when this spot / wide cleaning routine is executed through the operation of each button, the duty ratio Dt at the time of button operation is read (step S176). The water discharge hole swing angle α and the cleaning area (see FIG. 22) by the water discharge in the form of the pseudo-conical water discharge are defined by the duty ratio Dt as described above. Therefore,
By reading the current duty ratio Dt, the current water discharge hole swing angle α, that is, the cleaning area can be determined. Since the duty ratio Dt is stored in the RAM when the pulse signal is output, its value may be read.

In the present embodiment, as described above, the water discharge hole swing angle α (wash area) can be variously set through the duty ratio control (see FIG. 21). However, in the following description, for the sake of convenience, spot-wide button operation
Practical setting range of duty ratio Dt (Dtmin to Dtmin)
tmax; αmin to αmax: refer to FIG. 29) and duty ratio Dt (Dtmin <Dt) in three stages of large, medium and small
S <DtM <DtL <Dtmax) is set. That is, by setting the duty ratio Dt in three stages, the water discharge hole swing angle α (washing area) is increased or decreased in three stages.
Note that the cleaning area at the time of washing the buttocks is denoted as SMA, and the cleaning area at the time of bidet cleaning is denoted as SMV.

Following the reading of the current duty ratio Dt, the type of button operated (spot or wide)
The duty ratio Dt is increased or decreased in a stepwise manner according to (step S178), and this routine ends. Hereinafter, a state of the change of the cleaning area due to the increase and decrease of the duty ratio Dt will be specifically described.

Now, when the ass is cleaned, the wide setting button SWv
It is assumed that a is operated. By this button operation, the current duty ratio Dt is read in step S176,
It is assumed that the result is the duty ratio DtS. Then, in the following step S178, the current duty ratio DtS is set to the duty ratio DtM. Therefore, FIG.
As shown in FIG. 4, the cleaning area SMAS before the button operation based on the duty ratio DtS becomes the cleaning area SMAM corresponding to the duty ratio DtM, and the cleaning area increases. When the wide setting button SWva is further operated, the duty ratio DtM is set to the duty ratio DtL, and the cleaning area increases from the cleaning area SMAM to the cleaning area SMAL. That is, every time the wide setting button SWva is operated, the cleaning area is expanded and changed in the order of the cleaning area SMAS → the cleaning area SMAM → the cleaning area SMAL. When the spot setting button SWua is operated, the reverse is true. Each time the button is operated, the cleaning area is changed to the cleaning area SMAL.
→ The cleaning area SMAM → the cleaning area SMAS are reduced and changed. Note that the duty ratio DtS (the cleaning area SM
If the spot setting button is operated at the time of AS) or the wide setting button is operated at the duty ratio DtL (cleaning area SMAL), the duty ratio Dt and the cleaning area are maintained.

The same applies to the bidet cleaning, and every time the wide setting button SWvv is operated, the cleaning area is expanded and changed in the order of the cleaning area SMVS → the cleaning area SMVM → the cleaning area SMVL. Also, spot setting button SWu
Each time the operation v is performed, the cleaning area decreases and changes in the order of the cleaning area SMVL → the cleaning area SMVM → the cleaning area SMVS.

Therefore, the user operates the spot-wide setting buttons according to his / her own intention to arbitrarily expand and contract the cleaning area at the time of the local cleaning, and the cleaning area (the cleaning area) with the spouting water. Can be fulfilled to one's will. Therefore, it is possible to give the user a feeling of satisfaction in cleaning. In addition, if the cleaning area is expanded, the user receives a large amount of water discharged from the cleaning water, so that a soft feeling can be obtained. Conversely, if the washing area is reduced,
The user can get a feeling of irritation by flushing water into a narrow area. Therefore, according to the present embodiment, various washing feelings can be created.

Moreover, such a feeling of satisfying washing and various feelings of washing can be obtained by controlling the width of the washing area, that is, by controlling the duty ratio, and there is no need to use a special flow rate control together. Therefore, a feeling of sufficient cleaning and various feelings of cleaning can be created by simple control, which is preferable. In addition, flow control devices (for example,
Since it is not necessary to drive a flow control pump or a flow control valve, vibrations and operation noises associated with driving these devices are preferably suppressed.
Moreover, since there is no need to sharply adjust the flow rate, water hammer can be effectively avoided.

The duty ratio Dt control and the flow rate adjustment control that cause the change in the cleaning area can be performed simultaneously. For example, at the time of the reduction control of the duty ratio Dt, it is determined that the user wants a stimulating feeling, and the flow rate of the washing water is controlled to be increased. Conversely, at the time of increasing control of the duty ratio Dt,
Decrease and control the flow rate of the wash water as a soft feeling is desired. In this case, the washing feeling can be further diversified.

Further, in this embodiment, as shown in FIG. 34, the cleaning area (SMA, SM)
V) was different. Therefore, a feeling of washing satisfaction and a feeling of washing (soft feeling,
Irritation).

In the spot-wide cleaning shown in FIG.
The duty ratio Dt set by each spot-wide setting button is the same as the rewritten duty ratio Dt described above.
It is. Therefore, the duty ratio Dt is reset by the OFF signal of the seating sensor when the user rises from the toilet seat. Thus, when the user repeats the washing operation during the sitting, in the second and subsequent washing operations, the duty ratio set by each spot-wide setting button in the main washing driving process in step S144. The cleaning water is discharged at Dt. Therefore, in the case of repeated use, since the local cleaning can be performed with the duty ratio Dt (that is, the cleaning area) set by each spot-wide setting button at the time of the previous cleaning, the sense of incongruity at the time of repeated use can be eliminated. it can. In the present embodiment, the configuration in which the water discharge hole swing angle α (cleaning area) is increased or decreased in three stages is described. However, the configuration may be increased or decreased in two stages, or may be increased or decreased in four or more stages. good.

J1 / Massage Cleaning Routine Next, a massage cleaning routine executed by the local cleaning apparatus of this embodiment in conjunction with the above-described local cleaning will be described. FIG.
5 is a flowchart showing this massage cleaning routine, FIG. 36 is an explanatory diagram for explaining the state of massage cleaning, and FIG. 37 is an explanatory diagram for schematically explaining effects obtained by massage cleaning.

The massage washing routine shown in the flowchart of FIG. 35 is for changing the washing area regularly over the buttocks washing period to promote a feeling of defecation. This massage washing routine is interrupted during the operation of the buttocks washing by operating the massage setting button SWea (see FIG. 2).

As shown in FIG. 35, when this massage washing routine is executed through the operation of the massage setting button, the current duty ratio Dt at the time of operating the button is read (step S180), and then the duty ratio Dt is set. Three-stage duty ratio (DtS, DtM, Dt
L) is increased or decreased at a predetermined massage cycle TM (step S182). Then, the periodic increase / decrease of the duty ratio Dt is continued until the massage setting button is operated again to turn off the massage cleaning (step S18).
4). On the other hand, if the massage cleaning is turned off, the duty ratio Dt read in step S180 is set to return to the state before performing the massage cleaning (step S18).
6), end this routine. When the stop button is operated, the operation stop routine of FIG. 30 is executed prior to these processes, and the water supply is stopped and the nozzle is returned to the standby position.

While the duty ratio Dt is periodically increased or decreased in this way, as shown in FIG. 36, the duty ratio Dt is DtS → DtM → DtL → DtS → DtM.
A constant massage cycle TM as shown (subscript 1,
2, 3...). Therefore, along with this change in the duty ratio, the cleaning area also becomes SMAS → SM
It changes at a constant massage cycle TM such as AM → SMAL → SMAS → MASM. In this case, the above-described massage cycle TM in which the duty ratio Dt and the cleaning area are changed is a frequency ftm (= 1/1) determined by this cycle.
TM) is set to have a frequency (less than about 5 Hz) in a range that can be perceived as an intermittent stimulus to a repetitive stimulus to the human epidermis. Thus, when the cleaning area changes as described above, the user clearly senses this regular cleaning area change. Since the feeling of irritation received from the spouting water is different depending on the size of the washing area, the user is periodically subjected to strong and weak stimulation by this massage washing, and the feeling of defecation is promoted.

Note that the excitation cycle Tc of the electromagnetic coil at each duty ratio Dt is equal to its excitation frequency f (= 1 / T
c) is the dead band frequency described above (about 5 Hz or more;
60 Hz). Therefore, during the cleaning period (massage cycle TM) in each cleaning area, the user experiences a continuous flushing sensation as described above.

As described above, in the massage cleaning of this embodiment, the defecation sensation can be promoted by periodically changing the cleaning area related to the intensity of the stimulus through the periodic increase / decrease control of the duty ratio. There is no need to use flow rate control together. Therefore, a feeling of defecation can be given by simple control, which is preferable. In addition, since it is not necessary to drive a flow control device (for example, a flow control pump or a flow control valve), vibration and operation noise and water hammer associated with driving these devices are preferably suppressed. Furthermore, problems such as a problem of durability of the flow control device and an increase in size of the entire local cleaning device due to installation of the flow control device do not occur.

On the other hand, the duty ratio Dt increase / decrease control and the flow rate adjustment control for massage cleaning can be performed simultaneously. For example, at the time of the reduction control of the duty ratio Dt, the washing water flow rate is increased to increase the stimulation, and at the time of the increase control of the duty ratio Dt, the washing water flow rate is decreased to reduce the stimulation. In this way, the intensity of the stimulus can be amplified and the defecation can be effectively promoted. Further, if the adjustment control of the flow rate of the washing water, the swing rotation speed, the temperature and the like is linked and synchronized with the duty ratio Dt increase / decrease control, the feeling of defecation can be more effectively promoted.

In the above-described massage cleaning, the duty ratio Dt, and hence the cleaning area increase / decrease change cycle (massage cycle TM), was kept constant. However, if the frequency f (= 1 / TM) determined by this cycle is within the frequency range (less than about 5 Hz) that can be sensed as an intermittent stimulus to the repetitive stimulus to the human epidermis, the above-described increase / decrease change cycle (Massage period TM) can be changed each time the duty ratio Dt is increased or decreased. For example, in FIG. 36, the massage period with the duty ratio DtS (massage period TM1), the massage period with the duty ratio DtM (massage period TM2), and the massage period with the duty ratio DtL (massage period TM3) are different from each other. In this way, each cleaning area (SM
(AS, SMAM, SMAL), the recognition time of the stimulus is changed, so that the stimulus sensation is diversified and the defecation sensation can be more effectively promoted. In particular, the cleaning area SMA
When the time distribution of S is lengthened, a feeling of defecation can be promoted by an enema effect. This is because a large amount of water is injected into the anus for a long time in the washing area SMAS when the anus is relaxed in the washing area SMAL. In addition, by synchronizing with the five senses such as music, light, and odor (aromatherapy), a relaxing space can be provided, and further a feeling of defecation can be further promoted.

If this massage washing is performed not for promoting the feeling of defecation but for local washing after defecation, the following advantages can be obtained. First, since the user receives a strong stimulus due to the change in the cleaning area, the monotonous feeling at the time of local cleaning is eliminated or awakened. Secondly, as shown in FIG. 37, when the duty ratio Dt changes from DtL which is large to DtS, the schematic water discharge column RT moves toward the center as shown by a white arrow in the figure. Therefore, waste OB around the local area
Is effectively separated by this schematic water discharge column RT.
Moreover, the dirt OB is gathered toward the center side, and the rebound water RTH of the spouting wash water exhibiting the schematic water discharge column RT is collected, whereby the collected dirt OB is reliably removed. Therefore, according to the massage cleaning of the present embodiment, the local cleaning can be performed with a high cleaning ability. In the present embodiment, the configuration in which the cleaning area is increased or decreased in three stages has been described. In addition, these multi-step area differences may be synchronized with the five senses such as music, light, and smell.

K1 / fluctuation cleaning routine: Next, the fluctuation cleaning routine executed by the local cleaning apparatus of this embodiment in conjunction with the above-described local cleaning will be described. FIG. 38 is a flowchart showing the fluctuation cleaning routine, and FIG.
Is an explanatory diagram for explaining the processing content of the fluctuation cleaning routine, and FIG. 40 is an explanatory diagram for explaining the state of the fluctuation cleaning.

The fluctuation cleaning routine shown in the flowchart of FIG. 38 is for changing the cleaning area irregularly to give a sense of comfort and comfort. In the fluctuation cleaning routine, the fluctuation setting buttons SWta and SWtv (see FIG. 2) during the execution of the hip and bidet cleaning.
Is executed by the operation of.

As shown in FIG. 38, when this fluctuation cleaning routine is executed through the operation of the fluctuation setting button, the current duty ratio Dt at the time of button operation is read to return to the cleaning state before the fluctuation cleaning (step S190). . Next, the duty ratio Dt is irregularly increased or decreased at the predetermined fluctuation period TY to the above-described three-stage duty ratios (DtS, DtM, DtL) (step S192). And
The irregular increase / decrease of the duty ratio Dt is continued until the fluctuation setting button is operated again to turn off the fluctuation cleaning (step S194). On the other hand, if the fluctuation cleaning is turned off, the duty ratio Dt read in step S190 is set (step S196), and this routine ends. Thereby, it returns to the state before the execution of the fluctuation cleaning. When the stop button is operated, the water supply is stopped and the nozzle is returned to the standby position as in the case of the massage cleaning described above.

Here, an example of a method of irregularly increasing and decreasing the duty ratio Dt in step S192 will be described. The electronic control unit CT1-1 has a random number generation program in the ROM. Then, at the time of execution of step S192, the random number generation program is loaded every fluctuation period TY to generate a random number. On the other hand, the electronic control device C
T1-1 stores a duty ratio table in which a random number is associated with a duty ratio Dt, as shown in FIG. Therefore, the generated random numbers are checked against the duty ratio table, the duty ratio Dt is determined for each fluctuation period TY, and the duty ratio Dt is irregularly increased or decreased.

While the duty ratio Dt is irregularly increased and decreased in this way, as shown in FIG. 40, the duty ratio Dt is, for example, DtM → DtS → DtM → DtL →
A constant fluctuation period TY, such as DtS → DtS → DtL...
It transits. Therefore, with this duty ratio change,
Butt washing area is SMAM → SMAS → SMAM → SM
AL → SMAS → SMAS → SMAL ...
The bidet cleaning area is SMVM → SMVS → SMVM → SM
... VL → SMVS → SMVS → SMVL... In this case, the above-described fluctuation period T in which the duty ratio Dt and the cleaning area are changed
Y also has a frequency f determined by the fluctuation cycle TY.
(= 1 / TY) has the same frequency (less than about 5 Hz) as in the massage cycle TM. Accordingly, when the cleaning area changes as described above, the user clearly senses the cleaning area change. And since the sensation of stimulus received from the spouting water is different depending on the size of the washing area, and the change in the size of the washing area is also irregular, the user can receive the strong and weak stimulus irregularly by this fluctuation washing. Become. This has the following advantages.

The internal anal sphincter that opens and closes the anus for defecation is an involuntary muscle of the autonomic nervous system, and contracts and relaxes unconsciously. In the above-mentioned massage washing, since the washing area that affects the sense of irritation changes regularly, if this massage washing is continued for a long time,
The timing at which the cleaning area changes in a small amount may be predicted by the brain. For this reason, a change in the stimulus change due to a small change in the washing area is also expected, and the sympathetic nervous system becomes dominant, which may cause contraction of the internal anal sphincter. On the other hand, in the fluctuation cleaning in which the cleaning area changes irregularly, the timing of the narrow change of the cleaning area is hardly predicted, so that the change of the stimulus change accompanying the small change of the cleaning area is not expected. For this reason, the monotonous feeling at the time of washing is eliminated, and the parasympathetic nervous system becomes dominant, and the internal anal sphincter is easily unconsciously relaxed. As a result, according to the fluctuation massage washing described above, defecation can be more effectively promoted.

There is an external anal sphincter as a muscle that opens and closes the anus, and the external anal sphincter is a voluntary muscle of the somatic nervous system. By the way, inside the anus, there is a receptor that is sensitive to a stimulus. When water is delivered to the receptor and the stimulus is sensed, the external anal sphincter contracts by the action of the receptor. In a situation where the water discharge location (wash area) of the wash water changes regularly and repeatedly, that is, in the massage washing described above, the timing at which the wash area changes into a small area and the wash water spout enters the anus and reaches the receptor (water spout). The brain predicts the entry timing). Therefore, according to this prediction, the external anal sphincter is contracted in advance to close the anus, and it may be difficult for the flush water to enter the anus. On the other hand, in the fluctuation cleaning in which the cleaning area changes irregularly, the timing of the narrow change of the cleaning area is hard to be predicted, so that the brain cannot predict the above-mentioned water discharge entering timing. For this reason, while the external anal sphincter is not contracted, the chance of performing the flush water discharge in a small flush area increases, so that the flush water discharge easily enters the anus, and the flush water discharge enters the rectum. become. In general, the entry of washing water or the like into the rectum causes an enema effect, so that the above-mentioned fluctuation washing can promote defecation more effectively.

Further, if the fluctuation cleaning is performed for local cleaning after defecation, since it is difficult to predict a strong or weak stimulus due to a change in the cleaning area, a monotonous feeling at the time of local cleaning can be further eliminated.

The excitation cycle Tc of the electromagnetic coil at each duty ratio Dt is the same as in the massage cleaning described above, and the user has already described in the cleaning period (fluctuation cycle TY) in each cleaning area. As a result, a continuous feeling of spouting water is felt.

As described above, in this embodiment, when performing the above-described fluctuation cleaning, the cleaning area related to the intensity of the stimulus is only changed irregularly through the irregular increase / decrease control of the duty ratio. At this time, it is not necessary to use special flow rate adjustment control. Therefore, the above-mentioned defecation can be promoted by simple control, which is preferable. In addition, since it is not necessary to drive a flow control device (for example, a flow control pump or a flow control valve), vibration and operation noise and water hammer associated with driving these devices are preferably suppressed. Furthermore, problems such as a problem of durability of the flow control device and an increase in size of the entire local cleaning device due to installation of the flow control device do not occur.

On the other hand, the above-described control for increasing / decreasing the duty ratio Dt for fluctuation cleaning and flow rate adjustment control can be performed simultaneously. For example, when a smaller duty ratio Dt than before is determined by the generated random numbers (at the time of transition from the fluctuation period TY1 to TY2 or at the time of transition from TY4 to TY5 shown in FIG. 40), the flow rate of the washing water is increased in order to further increase the stimulation. Increase the duty ratio and increase the duty ratio Dt by using the generated random number.
Is determined (from the fluctuation period TY2 to TY3 in FIG. 40).
During the transition from TY3 to TY4, the flow rate of the washing water is controlled to decrease in order to weaken the stimulation. This makes it possible to more effectively promote defecation due to the strong amplification of the stimulus and the difficulty in predicting the stimulus.

In the above-described fluctuation cleaning, the duty ratio Dt, and thus the cleaning area increase / decrease change cycle (fluctuation cycle TY), was kept constant. However, if the frequency f (= 1 / TY) determined by this cycle is within a frequency range (less than about 5 Hz) that can be sensed as an intermittent stimulus to the repetitive stimulus to the human epidermis, the above-described increase / decrease change cycle is used. (Fluctuation cycle TY) can be changed every time the duty ratio Dt is increased or decreased, as in the case of massage cleaning. In this way, each cleaning area (SMAS, SMAM,
SMAL) changes the recognition time of the stimulus associated with
Prediction of irritability becomes more difficult. Therefore, defecation can be promoted more effectively.

Further, the power spectrum of the physical quantity such as the cycle TY or the instantaneous flow rate which determines the transition width of the cleaning area and the transition timing of the cleaning area is similar to the biological rhythm of the human body such as the heart rate and the rhythm of the natural world. Alternatively, it may be proportional to the reciprocal of the frequency. In this way, it becomes possible to give a sense of relaxation to the user, so that the parasympathetic nerve becomes dominant, causing relaxation of the internal anal sphincter,
The effect of promoting defecation increases.

The massage cleaning and the fluctuation cleaning described above can be executed simultaneously with the move cleaning. That is, when the move setting button SWfa and the massage setting button SWea are successively operated, the reciprocating movement of the nozzle back and forth and the periodic increase and decrease of the duty ratio Dt are simultaneously executed. Accordingly, the cleaning mode is such that the cleaning area periodically changes while the water discharge position (cleaning position) of the cleaning water changes in the range of the nozzle longitudinal movement. Then, the user receives local cleaning while recognizing the change in the cleaning position and the periodic change in the cleaning area.
For this reason, the new washing feeling that the local part is washed over an extremely wide area and the repetition of periodic strong and weak stimulation stimulate more effectively the defecation feeling, the elimination of the monotonous feeling at the time of the local washing, and the feeling of comfort. And satisfaction can be provided.

When the move setting button and the fluctuation setting button SWta, SWtv are operated one after another,
The nozzle reciprocating movement and the irregular increase / decrease of the duty ratio Dt are simultaneously executed. Accordingly, the cleaning mode is such that the water discharge position (the cleaning position) of the cleaning water changes in the range in which the nozzle moves in the longitudinal direction, and the cleaning area irregularly increases and decreases in an unpredictable state. Then, the user undergoes local cleaning in a situation where a change in the cleaning position and an unpredictable irregular change in the cleaning area occur. For this reason, the new washing feeling that the local part is washed over a very wide area and the repetition of unpredictable and irregular strong and weak stimuli further promote the more effective defecation feeling and the monotonous feeling at the time of the local washing. It is possible to achieve the cancellation and the addition of a feeling of comfort and a feeling of satisfaction.

Regarding the above-mentioned massage cleaning and fluctuation cleaning, controlling the cleaning area and cleaning strength for the purpose of promoting comfort and convenience is mainly mentioned here. In addition to this, the temperature of the cleaning water is also controlled. Of course, it may be changed.

L1 / Swing Detection Routine and Abnormality Recovery Routine Next, a description will be given of a movable body oscillation detection routine and an abnormality recovery routine performed by the local cleaning apparatus of this embodiment. FIG. 41 is a flowchart showing the swing detection routine,
FIG. 42 is an explanatory diagram for describing the processing content of the swing detection routine. FIG. 43 is a flowchart showing the abnormality recovery routine.

The swing detection routine shown in the flowchart of FIG. 41 is based on the above-mentioned movable body NH1-
This is to detect a swing abnormality when the coils 9 and 11 are swung by energization excitation of the electromagnetic coils, that is, an energization abnormality.
This swing detection routine is executed with priority at predetermined time intervals. In the following explanation,
Electromagnetic coil NH1-33a of bidet movable body NH1-11
33c will be described as an example.

As shown in FIG. 41, in this swing detection routine, it is determined whether or not the washing operation is being performed based on the operation state of the buttocks and bidet washing buttons (step S20).
0), if a negative determination is made, it is determined that swing detection is not necessary, and this routine is once ended. On the other hand, if it is determined that the cleaning operation is being performed, it is determined that the swing abnormality needs to be detected, and the process from step S205 is performed.

First, following an affirmative determination in step S200, the input waveform from output line NH1-37 shown in FIG. 20 is scanned (step S205), and the presence or absence of an abnormality in this input waveform is determined as follows. (Step S2
10). If each of the electromagnetic coils NH1-33a to 33c has no abnormality such as disconnection or contact failure, each pulse of the pulse output of the coil excitation output as shown in FIG. 21 includes an output line NH1-37 (see FIG. 20). Input pulses correspond one to one. Therefore, this input pulse has a pulse waveform without tooth missing (see FIG. 42A). On the other hand, if there is an abnormality such as disconnection or contact failure, the input pulse from the output line corresponding to the pulse output to the coil in which the abnormality has occurred is lost, so that the input pulse has a pulse waveform in which tooth missing has occurred. (See FIG. 42 (b)). Therefore, in step S210, the presence or absence of an abnormality is determined based on the waveform of the input pulse.

If a negative determination is made in step S210 that there is no abnormality, it is determined that the subsequent processing is unnecessary, and this routine is ended once. On the other hand, if it is determined that there is something abnormal,
In order to stop the swinging of the movable body and the discharge of the washing water while the abnormality is still present, the following processes from step S215 are executed.

That is, the above steps S154 to S155
The washing water is stopped in accordance with the same procedure (stopping the flow regulating pump and closing the solenoid valve), the output of the pulse signal for exciting the coil is stopped, and the washing nozzle is forcibly returned to the standby position (step S215). . Next, based on the input pulse waveform, an abnormal electromagnetic coil is determined, and the result is written and stored in the backup RAM (step S).
220). At the time of this writing, a value of 1 is set to the coil determination result (in the case of FIG. 42B, the electromagnetic coil NH1-33c) and the previously described cleaning operation prohibition flag FSstop. Thus, the cleaning operation inhibition flag FSsto
When the value 1 is set to p, the cleaning operation is not performed in the cleaning / drying operation routine after the execution of the swing detection routine (see FIG. 25; step S120). in this case,
Since the state of the cleaning operation prohibition flag is maintained even after the power is turned off, the cleaning operation is not executed even when the apparatus is turned off and then turned on. That is, regardless of whether the apparatus power is on or off, the cleaning operation cannot be performed if the cleaning operation prohibition flag FSstop is set to a value of zero in the abnormality recovery routine described below.

Then, following step S220, a message to that effect is issued (step S225) to prompt the recovery from an abnormality such as a disconnection or a defective contact (step S225), and this routine ends. Upon notification of this abnormality, blinking display is performed on the display section KS1-6 of the sleeve section KS1-5 shown in FIG. In order to distinguish the blinking display accompanying the abnormality notification from the display of the normal operation status, all the lighting devices (lamps, LEDs, etc.) may blink simultaneously.

When a swing abnormality is detected in the swing detection routine, the cleaning operation prohibition flag FSstop is set to a value of 1, and the cleaning operation is not executed in the subsequent washing / drying operation routine. However, the following configuration is also possible. Subsequent to the affirmative determination (FSstop = 1) in step S120 shown in FIG. 25, steps S130 to S130-1 are performed in a state where only energization to each electromagnetic coil is prohibited.
The process of 50 is executed. That is, at the time of detecting a swing abnormality, at least the pseudo swing rotation operation of the movable body is not performed. In this case, the local cleaning can be performed by spouting the cleaning water in a state where the pseudo swinging rotation of the movable body is prohibited, that is, in a state where the movable body is free. In this case, if the flow rate of the cleaning water in the main cleaning operation (step S150) is fixed at a smaller flow rate than the flow rate of the cleaning water at the time of execution of step S150 in the case where the quasi-oscillating rotation of the movable body is set, It is possible to prevent a user receiving intensive spouting from inadvertently feeling uncomfortable.

Next, a description will be given of an abnormality recovery routine after the swing abnormality has occurred. As shown in FIG.
In this abnormal recovery routine, first, it is determined whether or not there is a recovery completion command from a maintenance inspector or the like (step S300).
This judgment is made as follows. The maintenance inspector completes the abnormality recovery by the above-described abnormality notification. Specifically, the head cover NH1 in which the abnormality shown in FIG.
-6 is removed from the nozzle head base NH1-2, and a normal head cover is replaced by an external inspection device (not shown). When the parts replacement is completed in this way, the maintenance inspector performs button operations that are not operated during normal use of the apparatus, for example, simultaneous operation of a plurality of buttons or long-time operation of a specific button. If there is no such special button operation, the routine is terminated since it is determined that abnormality recovery has not been completed and subsequent processing is unnecessary. On the other hand, when the above-mentioned special button operation is performed, in step S300, it is determined that the completion command of the abnormal recovery has been issued, and the subsequent processing is executed.

First, the result of abnormality recovery is stored in the backup RAM.
Is written and stored (step S305). That is, the coil determination result stored in the above-described swing abnormality detection routine is reset, and the cleaning operation prohibition flag FSstop is set to a value of zero. As a result, after the execution of the abnormality recovery routine, the washing and drying operations can be executed according to the button operation. That is, the local cleaning device can be reused.

Subsequent to step S305, the abnormality notification is canceled upon completion of abnormality recovery (step S31).
0), end this routine. Specifically, the display unit KS
1-6 is returned to the display state of the normal operation status.

M1 / Nozzle Cleaning Routine: Next, the nozzle cleaning routine performed by the local cleaning device of this embodiment will be described. FIG. 44 is a flowchart showing this nozzle cleaning routine. This nozzle cleaning routine is executed in response to the operation of the nozzle cleaning button SWk on the sleeve KS1-5 (see FIG. 3) of the main body.

When the nozzle cleaning routine shown in the flowchart of FIG. 44 is executed, first, nozzle pre-cleaning is executed (step S400). That is, step S already described
Similarly to 120 (see FIGS. 25 and 26), nozzle head cleaning with functional water and nozzle head cleaning with splash cleaning water in the chamber are performed. Next, in order to prepare for the nozzle head cleaning by the user using a brush or the like, the cleaning nozzle WN1-1 advances to the buttocks cleaning position AWP (step S405), and waits until the user inputs a signal to end the nozzle cleaning. (Step S410). During this time, the user actually cleans the nozzle head with a brush or the like. After the cleaning is completed, the user operates the nozzle cleaning button SWk again or operates the stop button SWa to input the nozzle cleaning end signal.
Alternatively, an elapsed time after the operation of the nozzle cleaning button SWk is operated may be measured by a timer, and when the elapsed time becomes about 5 minutes, a signal indicating the end of the nozzle cleaning may be input. In addition,
From step S405, the washing nozzle may be advanced to the buttocks washing position to the end of the nozzle cleaning, a small amount of washing water may flow from the buttocks discharge hole. The washing water spouting at this time is sufficient if the washing water drips from the nozzle head to the toilet bowl portion.

When the nozzle cleaning is completed in this manner, the cleaning nozzle is retracted and returned to the standby position of the main body (step S415), and then the above-described step S160 (see FIG. 30) is performed.
The post-nozzle cleaning is performed in the same manner as described above (step S420), and this routine ends.

By executing the nozzle cleaning routine, in addition to the user cleaning the nozzle with a brush or the like, before and after the cleaning, the nozzle is cleaned twice with functional water, and the nozzle head is repelled with washing water in the chamber. Cleaning is performed. Therefore, it is possible to clean the nozzle head, and furthermore, the water discharge holes of the cleaning water and the periphery thereof.

Next, a modified example of the above-described local cleaning device KS1-1 will be described. Note that, for members performing the same function, the member names and symbols used in the above-described embodiment are used as they are, and description thereof is omitted.

A1-1 / Modification of Overall Configuration: In the remote control device RC1-1, the spot setting button and the wide setting button are provided for each of the ass washing and the bidet washing. And bidet cleaning can also be used. In this case, the number of buttons is reduced, and there are advantages in manufacturing such as reduction in the number of assembling steps and cost reduction.

B1-1: Modification of Channel System Configuration; FIG.
It is a block diagram showing the waterway structure of a modification.

(1) In the water channel system, the second washing water outlet pipe WP1-13 is provided on the upstream side of the heat exchange unit TH1-1, but the pipe is provided downstream of the heat exchange unit. You can also. In this case, the flow rate of the washing water flowing into the heat exchange unit is stabilized, and therefore, it is preferable to easily control the heater for maintaining the temperature of the washing water. In addition, the washing water that has been heated in the heat exchange unit can be discharged from the second washing water outlet pipe to the deodorizing intake port and the local drying exhaust port to clean the intake port and the exhaust port. This is preferable because dirt on the intake port and the exhaust port can be more effectively washed off with warm water.

(2) In the waterway system, the water outlet side valve unit WP1-3 downstream of the heat exchange unit TH1-1 is composed of the flow regulating pump WP1-14 and the switching valve WP1-15. It is also possible to use a flow control switching valve (not shown) having a two-way valve structure and capable of flow control. In this case, a smaller and less expensive structure can be obtained, and problems of vibration and noise can be eliminated because no pump is used.

(3) In the water channel system, a flow regulating pump is used for the water outlet side valve units WP1-3, or a flow regulating switching valve is used to perform flow regulation.
The water channel configuration shown in FIG. That is, as shown in the figure, the bypass flow control valve W that can make the water passage area variable in the middle of the second washing water outlet pipe WP1-13.
P1-20 is provided. Therefore, the flow rate of the difference between the flow rate adjusted by the bypass flow control valve WP1-20 and the set flow rate by the constant flow rate valve WP1-9 is determined by the water discharge side valve unit WP1.
Water is discharged from the nozzle through -3. In this case, since no pump is used, there is no problem of vibration and noise, and there is no need to use a complicated structure such as a flow control switching valve.

(4) Although the heat exchange unit TH1-1 has a heater made of a spiral nichrome wire built in a small-capacity tank, the following is also possible. That is, if the heater is a laminated cylindrical ceramic heater, the leakage detection circuit and the overheat prevention circuit can be printed on the green sheet before firing, and each circuit can be formed on the heater surface by firing.
Therefore, an external leakage detection / leakage protection circuit is not required outside, and an overheat prevention device such as a bimetal is not required. The heat exchange unit can be reduced in size by stacking and omitting the equipment. Further, the heater may be an electromagnetic induction heater that causes electromagnetic induction in the resistor by a change in magnetic flux linked to the high-frequency current and generates the resistor by Joule heat. In this case, since it is not necessary to dispose the heater in the tank, the leakage protection circuit becomes unnecessary, and the size can be reduced accordingly. Further, since the degree of freedom of the shape of the heater is high, the shape of the heater can be formed along a meandering channel, and the washing water can be efficiently heated.

(5) The heat exchange unit TH1-1 may be of a hot water storage type instead of an instantaneous type. This makes it possible to extend the continuous water discharge time of the cleaning water at the predetermined temperature. In addition, warming of the washing water in the tank can be performed when the toilet is not used, such as at midnight, and in that case, a heater with low power consumption can be used. In this way, the maximum power consumption of the entire local cleaning device can be reduced, and when installing the local cleaning device in an existing toilet, the indoor wiring capacity may be insufficient or the capacity contract may be changed. Is reduced.

(6) The functional water units WP1-4 are configured to generate a free chlorine by applying a DC voltage in a state where the washing water is stored in the tank. When a sufficient free chlorine generating ability is obtained by, for example, increasing the surface area of the chlorine generating electrode, a direct current voltage can be applied in a water-flowing state. In this case, the functional water can be continuously discharged for a long time, and the cleaning nozzle can be kept more hygienic.

C1-1 / Modification of Nozzle Device; FIG.
FIG. 47 is a schematic sectional view taken along line 47-47 in FIG. 46, illustrating a nozzle device NS1-20 of a modified example.

As shown, the nozzle device NS of the modified example is
1-20 is an arc-shaped nozzle advance / retreat trajectory NS for cleaning nozzles.
It is common to the above-described nozzle device NS1-1 in that it is advanced and retracted by the transmission mechanism NS1-5 along 1-12 (see FIG. 7), but the configuration related to the guide rail of the nozzle is different.
That is, the nozzle device NS1-20 of this modified example includes an arc-shaped nozzle advance / retreat trajectory NS1- extending between the pedestal NS1-3 on the rear end upper surface of the base NS1-2 and the nozzle holding portion NS1-6 on the front end side of the base. 12 has a guide rail portion NS1-21 which is formed to be curved so as to coincide with the same. As shown in FIG. 47, the cleaning nozzle WN1-20 guided by the guide rail portion has a timing belt NS1-1 at its rear end side.
And a track gripper WN1-21, which grips and holds the guide rail portion NS1-21 up and down on the right and left rail portions. The track gripper has upper and lower track gripping surfaces having the same radius of curvature as the nozzle advance / retreat track, and the track gripping surface is slidable with respect to the guide rail. That is, the cleaning nozzle WN1-20 and the guide rail portion NS1-21 are disposed in a vertical positional relationship, and the cleaning nozzle is engaged with the guide rail portion by the track gripping body only on the rear end side. ing. Note that, even in the cleaning nozzle WN1-20, the cylindrical portion is formed to have the same radius of curvature as the nozzle advance / retreat trajectory and to be curved along the axial direction.

Therefore, the nozzle device NS1-
20, the standby position HP and the cleaning position (the butt cleaning position AW)
P, bidet cleaning position VWP; see FIG. 7). Therefore, the nozzle device NS of this modified example
According to 1-20, advantages such as a reduction in the height of the slip can be exhibited in the same manner as the above-described nozzle device NS1-1. Further, in the nozzle device of this modified example, the positional relationship between the cleaning nozzle and the guide rail portion allows the compactness in the width direction, and allows the nozzle device and other devices to be arranged close to each other.

F1-1: Modification of Cleaning Operation: In this modification of the cleaning operation, the excitation order of each electromagnetic coil is reversed every predetermined period while performing the local cleaning of the hips and bidet. That is, while keeping the duty ratio Dt the same, the electromagnetic coils NH1-33a → 33b → 33c → 33
coil excitation in the order of a... and electromagnetic coils NH1-3
The coil excitation in the order of 3c → 33b → 33a → 33c... Is repeated. In this case, since the direction of spouting of the spouting wash water is switched, the inside of the wrinkles of the epidermis around the local area can be more effectively washed, which is preferable.

H1-1 / Modification of move cleaning; FIG.
It is an explanatory view for explaining a situation of move cleaning of a modification.

In the move cleaning of this modified example, step S170 in the flowchart of the move cleaning routine shown in FIG. The variable control is executed. For example,
When the nozzle head is near the center position (washing position WPc) of the nozzle front-back movement range, the duty ratio Dt is set to the maximum duty ratio Dtmax of the practicable setting range. Then, the nozzle head is moved from the center position to the forward end position W.
As the distance from Pf / retreat end position WPb increases, the duty ratio D
t is reduced from the duty ratio Dtmax so that at the forward end position WPf and the backward end position WPb, the minimum duty ratio Dtmin in the practicable setting range is set. In this case, the cleaning area is large near the center position, and the cleaning area is narrowed toward the forward end or the retreat end, so that the local periphery can be move-cleaned (see FIG. 48A). Therefore,
Various washing feelings can be provided in which the washing area increases or decreases in accordance with the change in the washing position, that is, the stimulus sensation changes in a strong or weak manner in accordance with the washing position change. Further, since the entire cleaning area shape over the range of the reciprocating movement of the nozzles can be widened at the center position and narrowed at the front and rear ends, the cleaning area is adapted to the shape of the local area to be cleaned to be cleaned. For example, there is an advantage that the local part of the bidet can be reliably washed.

In variable control of the duty ratio Dt according to the nozzle position, the center position (the cleaning position WP)
c) When it is near, the duty ratio Dt is set to the center duty ratio Dtmid of the practicable setting range, and the duty ratio Dtmax is set at the forward end position WPf and the backward end position WPb.
And Then, from the center position to each end position, the value is increased or decreased in the order of Dtmid → Dtmin → Dtmax. With this arrangement, the cleaning area can be moved around the center position, the cleaning area can be large at the forward end / retreat end positions, and the cleaning area can be changed by increasing or decreasing during that time (FIG. 48B). reference). Therefore, in addition to the various washing feelings in which the stimulus sensation changes in accordance with the washing position change, the effect of being able to carefully wash the front and the back of the washing target with a large washing area can be obtained.

Further, since the front and rear portions of the local area to be cleaned can be cleaned with a large cleaning area as described above, even if the moving range of the cleaning nozzle is narrowed, the peripheral area of the local area to be cleaned can be cleaned without any trouble. For this reason, the number of nozzle reciprocations can be increased, and the cleaning effect can be improved accordingly.

Note that the variable control of the duty ratio Dt according to the nozzle position is performed by changing the duty ratio (D
(tS, DtM, DtL). In this case, it is only necessary to switch the duty ratio Dt in accordance with the nozzle position, so that the control is facilitated and the calculation load of the electronic control unit can be reduced.

J1-1: Modification of Massage Cleaning: In this modification of massage cleaning, the periodic increase / decrease control of the duty ratio Dt in step S182 of the massage cleaning routine (see FIG. 35) described above is performed as follows. That is,
The massage cycle TM of the duty ratio Dt shown in FIG. 36 for increasing or decreasing the cleaning area is set to a frequency ftm determined by this cycle.
(= 1 / TM) is set to the dead band frequency (about 5 Hz or more; about 10 to 60 Hz). In this case, the cleaning area can be quickly changed in size without making the user sense the transition of the cleaning area. Therefore, the movement toward the center of the schematic water discharge column RT shown in FIG. 37 and the spread from the center are repeated at a high speed, so that the effect of removing the dirt OB around the local area is enhanced, and the repelling water RTH of the water discharge cleaning water.
The garbage OB gathering effect due to is also increased. Therefore, according to the massage cleaning of this modified example, it is possible to perform the local cleaning with higher cleaning performance and the elaborate local cleaning. In this case, the massage cycle TM in this modified example of the massage cleaning is excited so as to be longer than the excitation cycle Tc of the electromagnetic coil at each duty ratio Dt, that is, the frequency ftm (= 1 / TM) determined in each cycle. The frequency is set to be lower than the frequency f (= 1 / Tc).

[0211] In this modification of the massage washing,
Through the operation of a special operation button such as a careful cleaning provided in a remote control device or an auxiliary operation unit, or through the simultaneous operation of a massage setting button and other operation buttons, the processing of the modified example of the massage cleaning may be performed. I just need.

E1-2 / Modification of Nozzle Head; FIG.
Is a plan view of an electromagnetic coil installation substrate NH1-50 of a nozzle head according to a modification, and FIG. 50 is a plan view of an electromagnetic coil installation substrate NH1-60 of a nozzle head of another modification.

(1) As shown in FIG. 49, the electromagnetic coil installation board NH1-50 of the modified example includes a hip rocking coil group N
H1-51 and a bidet swing coil group NH1-52. The butt swing coil group NH1-51 includes an electromagnetic coil N
H1-32b and 32c are connected to the bidet swing coil group NH1-
52 has electromagnetic coils NH1-33a and 33c, and both coil groups share one electromagnetic coil NH1-53. This electromagnetic coil NH1-53 has two coil cores NH1-54 and 55, similarly to the electromagnetic coil described above.
And one coil core 55 has a coil NH1-56. The electromagnetic coil NH1-53 is provided in a bidet swing coil group such that the coil core NH1-54 corresponds to the magnetic action portion NH1-23a of the magnetic driver NH1-23 in the hip swing coil group. Iron core NH1-55
Is the magnetic action part NH1-18b of the magnetic driver NH1-18
It is arranged and fixed to correspond to. In this case, the number of electromagnetic coils provided is reduced, and there are advantages in manufacturing such as a reduction in the number of assembling steps and a reduction in cost. Further, the two coil groups can be arranged close to each other, and the size of the nozzle head can be reduced accordingly.

(2) As shown in FIG. 50, the electromagnetic coil installation board NH1-60 of another modified example has both coils of a hip rocking coil group NH1-61 and a bidet rocking coil group NH1-62. For each group, a coil core NH1-
There are provided electromagnetic coils NH1-65a to 65c and 66a to 66c each including a coil 63 and a coil NH1-64 wound therearound. Then, the electromagnetic coil NH1 of the two rocking coil groups
-65a to 65c and 66a to 66c are disposed and fixed on the substrate so as to face the magnetic action portions NH1-18a to 18c and 23a to 23c of the magnetic drivers NH1-18 and 23 in the buttocks and bidet movable bodies. Have been. In this case, the number of components of the electromagnetic coil is reduced, and there are advantages in manufacturing such as reduction in the number of assembling steps and cost reduction. Further, since the size of the electromagnetic coil itself is reduced, the two coil groups can be arranged closer to each other, and the nozzle head can be further reduced in size.

E1-3 / Another Modification of Nozzle Head; FIG.
FIG. 1 is an explanatory diagram for explaining a nozzle head of still another modified example.

As shown, the nozzle head NH1-70 of this modification has a bidet movable body NH1 having four magnetic action portions NH1-18a-18d formed at equal pitches.
1-11, and a bidet swing coil group NH1-71 having four electromagnetic coils NH1-33a to 33d arranged and fixed to face the respective magnetic action portions. And
In this modification, each of these electromagnetic coils is replaced by an electromagnetic coil NH
The magnets are sequentially excited in the order of 1-33a to 33d or in the reverse order to rotate the bidet movable body NH1-11 in a pseudo swinging manner, as described above, and eventually swing the bidet discharge hole NH1-10 (see FIG. 22, see FIG. 23). According to the nozzle head NH1-70 of this modification, the magnetic action part NH1-
Since the number of inclined portions of the bidet movable body due to the coil acting force on 18a to 18d increases, the trajectory of the pseudo swinging rotation of the movable body and the swinging rotation of the bidet discharge hole is approximated to a circular locus due to the increase of the inclined portion. Then, the cleaning water can be spouted. In addition, the movable body may have a multi-divided magnetic action portion such as a five-split or six-split portion, or the buttocks movable body may have such a multi-split magnetic action portion.

F1-2 / Modification of cleaning operation; FIG. 52 is an explanatory view for explaining a cleaning operation of a modification using the nozzle head NH1-70 of the above modification, and FIG. 53 is a diagram of this modification. It is explanatory drawing for demonstrating typically the state of washing water spouting by a washing | cleaning operation. In the following description, the bidet cleaning will be described as an example, but the same applies to the bottom cleaning.

In this modification of the cleaning operation, the duty ratios Dt (Dta, Dtc) of the electromagnetic coils NH1-33a, 33c located in the front-rear direction of the nozzle are the same when the respective electromagnetic coils are sequentially excited. In the electromagnetic coils NH1-33b and 33d located in the left-right direction,
The duty ratios Dt (Dtb, Dtd) were the same. Moreover, the former duty ratio Dt (Dta, Dtc) is different from the latter duty ratio Dt (Dtb, Dtd). That is, as shown in FIG. 52, in the cleaning period TA, the duty ratios Dta and Dtc of the electromagnetic coils NH1-33a and 33c are changed to the values of the electromagnetic coils NH1-33b and 33d.
Duty ratios Dtb and Dtd. With this, when the electromagnetic coils NH1-33a and 33c exert a coil acting force on the magnetic acting portions NH1-18a and 18c to tilt the bidet movable body, the water discharge hole swing angle αac is large and the electromagnetic coils NH1-33b , 33d, the water discharge hole swing angle αbd becomes smaller. Therefore, as shown in FIG. 53A, the cleaning area SMTA in this cleaning period TA
Has an elliptical shape whose major axis is in the front-back direction of the nozzle.

In the cleaning period TB, the duty ratio Dta,
Dtc is made longer than the cleaning period TA. Therefore, FIG.
As shown in (a), the cleaning area SMTB in the cleaning period TB has an elliptical shape whose major axis is in the front-rear direction of the nozzle similarly to the cleaning area SMTA, but the major axis extends and the cleaning area increases.

In the cleaning period TC, contrary to the cleaning period TA, the duty ratios Dta and Dtc are changed to the duty ratio Dt.
b, smaller than Dtd. Thereby, the electromagnetic coil N
When the movable body for bidet tilts due to H1-33a, 33c, the swing angle αac of the water discharge hole is small, and the electromagnetic coil NH1-3
In the cases of 3b and 33d, the water discharge hole swing angle αbd becomes large. Therefore, as shown in FIG. 50B, the cleaning area SMTC in the cleaning period TC has an elliptical shape whose major axis is in the nozzle left-right direction. And the duty ratio Dt
If b and Dtd are increased, the cleaning area can be enlarged to an elliptical shape having the major axis extending in the left-right direction of the nozzle and extending with the major axis, as in the case of FIG.

According to the modification of the cleaning operation, there are the following advantages.

(1) As in the cleaning periods TA and TB, the local cleaning is performed in an elliptical cleaning area having the long axis in the front-rear direction of the nozzle. In addition, it is possible to perform a wide range of local cleaning along the front-back direction of the nozzle. Therefore, the move cleaning can be executed in a quiet state without the operation noise caused by the forward / reverse rotation of the motor, and a sense of relaxation can be given to the user. Further, since the forward / reverse rotation control of the motor is not required, the control load on the electronic control device can be reduced. Furthermore, since the nozzle drive motor does not need to have high responsiveness to repetition of forward and reverse rotation, a high-performance motor is not required, and cost reduction and downsizing of the motor can be achieved. In addition, the wear of the guide rail portion NS1-7 (see FIG. 6) due to the repetition of the nozzle reciprocating motion can be suppressed, and the durability of the rail portion can be improved.

(2) When the move cleaning is performed by reciprocating the nozzle back and forth while keeping the cleaning area of the elliptical shape like the cleaning period TA or TB, the longitudinal movement interval of the nozzle can be shortened.

(3) It is also possible to perform move cleaning by reciprocating the nozzle back and forth while maintaining an elliptical cleaning area as in the cleaning period TC. By doing so, the move cleaning can be performed in a wide range in the left-right direction of the nozzle. In this case, as described with reference to FIG. 48, if the duty ratios Dtb and Dtd are increased or decreased according to the nozzle head position in the nozzle longitudinal movement range,
The elliptical shape of the cleaning area can be deformed long and short in the left-right direction of the nozzle according to the position of the nozzle head. Therefore, it is possible to provide various washing feelings in which the stimulus sensation changes in accordance with the washing position change.

(4) If the duty ratios Dta and Dtc are equal to the duty ratios Dtb and Dtd, the water discharge hole swing angles αac and αbd become the same, and the cleaning area can be made circular. Therefore, through the variable control of the duty ratio Dt, in the execution period of the local cleaning, a cleaning period in which a circular cleaning area is used, a cleaning period in which the elliptical cleaning area in which the longitudinal direction of the nozzle takes a long axis, The cleaning period in which the direction takes a cleaning area having an elliptical shape with a long axis can be expressed in an arbitrary order. In addition, in changing each cleaning area at this time, the frequency f determined by the cycle of each cleaning period (for example, the cleaning periods TA, TB, and TC in FIG. 52) is used as an intermittent stimulus with respect to the repetitive stimulus to the human body epidermis. The frequency should be within a perceptible range (less than about 5 Hz). In this way, the user can clearly recognize the change in the shape of each washing area and give a strong stimulus according to the change in the washing area, so that the way of receiving the stimulus diversifies and effectively promotes a feeling of defecation. , A monotonous feeling can be eliminated.

F1-3 / Another Modification of Cleaning Operation; FIG.
55 is an explanatory diagram for describing a cleaning operation of another modified example using the nozzle head NH1-70 of the above modified example, FIG.
FIG. 56 is an explanatory view schematically illustrating a state of water discharge of cleaning water by the cleaning operation of this another modified example. FIG. FIG. 4 is an explanatory diagram for schematically explaining the state of FIG.

In this other modification, when the respective electromagnetic coils are sequentially excited, the remaining three electromagnetic coils except one of the electromagnetic coils NH1-33a and 33c positioned in the front-back direction of the nozzle, or the left-right direction of the nozzle. In order to sequentially excite the remaining three electromagnetic coils except one of the positioned electromagnetic coils NH1-33b and 33d, first, in the first method, as shown in FIG.
As shown in FIG. 4 (a), the electromagnetic coils other than the electromagnetic coils NH1-33c are replaced by 33b → 33a → 33d → 33a → 3
Are sequentially excited in the order of 3b → 33a. In the second method, as shown in FIG. 54B, 33a → 33b → 33
Excitation is sequentially performed in the order of d → 33a → 33b → 33d. In the third method, as shown in FIG.
b → 33c → 33d → 33c → 33b → 33c... In the fourth method, as shown in FIG. 54 (d), 33b → 33c → 33d → 33b → 33c →
33d... Are sequentially excited.

When excitation is performed by the above-described first method, FIG.
As shown by an arrow Ha in FIG. 5A, the water discharge hole swings and rotates along an arc-shaped trajectory on the front side of the nozzle head, so that the cleaning water follows the trajectory of the water discharge hole on the front side of the nozzle head. Water is discharged in an arc. In the case of excitation by the second method, as shown by an arrow Hb in FIG. 55B, the water discharge hole swings and rotates in a semicircular locus on the front side of the nozzle head. Water is discharged at the front side of the nozzle head following the trajectory, and the cleaning area at that time becomes a semicircular shape. As shown in FIG. 55 (c), the cleaning water spouting in both methods takes a water spouting form directed toward the front of the nozzle head.

On the other hand, when the excitation is performed by the third method, FIG.
As shown by an arrow Hd in FIG. 5D, the water discharge hole swings and rotates on an arc-shaped trajectory behind the nozzle head, and the cleaning water is discharged in an arc shape behind the nozzle head. In the case of excitation by the fourth method, as shown by an arrow He in FIG. 55E, the water discharge hole swings and rotates with a semicircular locus on the rear side of the nozzle head, and the cleaning area becomes a semicircular shape. Thus, the washing water is discharged at the rear side of the nozzle head. As shown in FIG. 55 (f), the flush water spouting in both of these methods takes a form of spouting water toward the rear of the nozzle head. When exciting each electromagnetic coil in the excitation order of each of the above methods, the duty ratio Dt is controlled to increase or decrease to change the water discharge hole swing angle α, change the water discharge angle of the forward / rearward water discharge, or wash the semicircular shape. The area may be made semi-elliptical.

According to the modification of the cleaning operation, there are the following advantages.

(1) Through the duty ratio control shown in FIG. 54, as shown in FIG. 55, it is possible to arbitrarily change the washing water direction to the front or rear of the nozzle head or change the arc-shaped or semi-circular cleaning area. Can be taken in order. In addition, in changing the direction of water discharge and the washing area at this time, the frequency f determined by the change cycle is set to a frequency within a range that can be sensed as an intermittent stimulation with respect to the repetitive stimulation to the human epidermis (about 5).
(Less than Hz). In this way, the user can clearly recognize the change in the water discharge direction and the change in the shape of the cleaning area, and gives a strong stimulus accompanying the change in the water discharge direction and the change in the cleaning area. It is possible to promote a defecation feeling and to eliminate a monotonous feeling.

(2) Move cleaning can be performed by reciprocating the nozzle back and forth while taking the form of water discharge directed toward the front of the nozzle head shown in FIGS. 55 (a) to (c). In this case, the cleaning water can be discharged from the direction toward the front side of the nozzle head to the local waste. In addition to the fact that the trajectory of the reciprocating movement of the nozzle back and forth is directed obliquely downward as shown in FIG. 7, dirt can be effectively peeled downward.

(3) Conversely, the move cleaning can be performed by reciprocating the nozzle back and forth while taking the form of water discharge toward the rear of the nozzle head shown in FIGS. 55 (d) to (f). In this case, the cleaning water can be spouted from the direction toward the rear side of the nozzle head to the local waste. In addition to the fact that the trajectory of the reciprocating movement of the nozzles in the forward and backward directions is directed downward, it is possible to make it difficult for the spouted washing water and the dirt separated by the washing water to flow forward. Therefore, when the bidet cleaning is performed by this move cleaning, the cleanliness around the local area is enhanced, which is preferable.

(4) The nozzle moving direction and the water discharge direction can be matched. That is, at the time of the nozzle forward movement from the retreat end to the forward end of the nozzle back-and-forth reciprocal movement range, the nozzle head is in the form of water spray toward the front, and at the time of the nozzle retreat movement from the forward end to the backward end, The water discharge mode is directed toward the rear of the nozzle head. In this way, the waste can be effectively peeled downward when the nozzle advances, and it is difficult for the waste to flow forward when the nozzle moves backward, so that the cleanliness around the local area can be improved.

(5) Reciprocating the nozzle back and forth between the water discharge mode directed toward the front of the nozzle head shown in FIGS. It is also possible to execute move cleaning that switches according to the position of the moving nozzle head. That is, as shown in FIG. 56 (a), when the nozzle moves toward the center position from the retreat end of the nozzle back-and-forth reciprocation range, the nozzle head is in a water-spouting form toward the front of the nozzle head. The electromagnetic coil is sequentially excited with a uniform duty ratio Dt to form a water discharge mode in which the water is directed upward to the water discharge hole. Further, when the nozzle is moved from the center position toward the forward end, a water discharge form directed toward the rear of the nozzle head is adopted. In this way, local cleaning can be performed while collecting dirt in front of and behind the local part to be cleaned at the local skin position corresponding to the center position. Moreover, when the nozzle is advanced to the center position, the dirt can be effectively peeled downward, and when the nozzle is retracted to the center position, the dirt is less likely to flow forward and the cleanliness around the local area can be enhanced.

(6) As shown in FIG. 56 (b), when the nozzle moves from the retreat end to the center position, the water discharge form toward the rear of the nozzle head, and before and after the center position, the water discharge form that faces upward, When the nozzle is moved from the nozzle head to the forward end, a water discharge form directed toward the front of the nozzle head is adopted. With this configuration, the cleaning area during the move cleaning can be enlarged in the front-rear direction of the nozzle, so that a sufficient cleaning feeling can be provided over a wide range. Further, since the cleaning area can be increased in this manner, the reciprocating range of the front-rear movement of the nozzle can be narrowed. In the case of adopting the water discharge form shown in FIGS. 55 (a) and (d), when the wash water is discharged following the arc-shaped trajectory,
Since the switching of the water discharge direction of the water discharge at the end of the arc occurs, it is possible to more effectively clean the inside of the wrinkles of the epidermis around the local area, which is preferable.

(7) When performing the above-mentioned move cleaning while adopting the water discharge form shown in FIGS. 55 (b) and (e), the excitation order of the electromagnetic coil should be changed between when the nozzle moves forward and when it moves backward. It may be reversed. That is, 33a in FIG.
Excitation in the order of → 33b → 33d → 33a → 33b → 33d... And reverse 33d → 33b → 33a → 33d
The excitation in the order of → 33b → 33a... Is switched between forward and backward of the nozzle. Also, 33b → 33c in FIG.
Excitation in the order of → 33d → 33b → 33c → 33d... And the reverse 33d → 33c → 33b → 33d → 33
Excitation in the order of c → 33b... is switched between forward and backward of the nozzle. In this case, since the direction of spouting of the spouting wash water is switched, the inside of the wrinkles of the epidermis around the local area can be more effectively washed, which is preferable.

F1-4 / Another Modification of Cleaning Operation: The cleaning operation of this modification is the same as that of the modification (F1-3) shown in FIG.
As shown in FIG. 4, one electromagnetic coil N in the front-rear direction of the nozzle
While the H1-33a and 33c are not excited, one of the electromagnetic coils NH1-33b and 33d in the lateral direction of the nozzle is not excited, and the remaining electromagnetic coils are sequentially excited. According to this modification, the following water discharge form can be adopted.

That is, since the excitation is performed in accordance with the above-described first to fourth methods, the water discharge form in which the cleaning water is discharged in an arc shape on the left or right side of the nozzle head or the left side of the nozzle head It is possible to adopt a water discharge mode in which the cleaning water is discharged so as to have a semicircular cleaning area on the right or right side. In addition, a water discharge mode facing the left or right side of the nozzle head can be adopted. Furthermore, through the duty ratio increase / decrease control at the time of sequential excitation of each electromagnetic coil,
It is also possible to change the spouting angle of the spouting water to the left or right and to make the semi-circular cleaning area semi-elliptical. As described above, since the water can be dispensed to one side of the left and right, if there is a hemorrhoid or a laceration on the left or right side of the local part, the local water is washed so that the water does not hit the hemorrhoid or the like. It can be performed. Further, by combining with the move cleaning, the diversification of the cleaning feeling can be achieved as in the above-described modification.

F1-5: Still Another Modification of Cleaning Operation; The cleaning operation of this modification is the same as that of the above modification (F1-3, -4).
Does not excite one of the electromagnetic coils in the front-rear direction of the nozzle or the left-right direction of the nozzle, while setting the duty ratio Dt of this one electromagnetic coil to a duty ratio Dt different from the remaining electromagnetic coils to sequentially excite all the electromagnetic coils. There is a feature in the point.

That is, as for the non-excited electromagnetic coils in FIG. 54, for example, the electromagnetic coils NH1-33c in FIG.
b, the excitation is performed, and then the electromagnetic coils NH1-33d
To excite. The excitation in this order is repeated, and the duty ratio Dtc of the electromagnetic coil NH1-33c is changed to the duty ratios Dta, Dtb, Dtc of the other electromagnetic coils.
Make it smaller or larger. In this case, since the excitation is performed sequentially, the cleaning water can be spouted in the cleaning area having the irregular shape in the area corresponding to the electromagnetic coil NH1-33c while taking a closed cleaning area. At this time, the degree of irregularity of the area contour of the portion corresponding to the electromagnetic coil NH1-33c can be variously changed by the duty ratio Dt of this coil. Therefore, it is possible to perform the cleaning water spouting with various cleaning area shapes, and it is possible to diversify the feeling of cleaning. It should be noted that, when sequentially exciting each electromagnetic coil, a modification may be made such that the duty ratio Dt of each coil is set randomly while sequentially exciting. In this case, since the shape of the cleaning area becomes more diversified, the diversification of the cleaning feeling is also increased.

As described above, by controlling the excitation of each coil, the cleaning position and shape can be freely set.
For example, a touch panel is provided on a remote control device (not shown), and a user touches a position indicated on the panel to specify a cleaning part or a shape, or a stick-like operation lever is used to specify a cleaning part. In addition to being able to follow quickly when performing operations such as moving, there is little (or no) movement of the nozzle, so there is little (or no) noise, making it possible to use it comfortably. Become.

Here, a description will be given of a modified example of the movable body for causing the above-mentioned oscillating rotation water discharge of the washing water, taking a bidet movable body as an example. FIG. 57 is an explanatory view for explaining the manufacturing process of the bidet movable body NH1-11, FIG. 58 is an explanatory view for explaining the manufacturing process of the bidet movable body of the modification, and FIG. It is an explanatory view for explaining a manufacturing process of the movable body for use.

In the bidet movable body NH1-11 of this embodiment, as described above, the magnetic action portions NH1-18a to 18c
The magnetic driving body NH1-18 having a peripheral portion with the resin water discharging piece NH1-17 is integrated by an insert molding method or the like. At this time, as shown in FIG. 57 and FIG. 13, the magnetic driving body is integrated such that the lower end portion of the resin water discharge piece goes around the upper and lower surfaces of the peripheral portion NH1-18x connecting the magnetic action portions. I have. At this time, the anchor hole NH in the peripheral portion
Since the resin also enters 1-18y,
Stronger integration is achieved by the anchor effect. In this method, the members to be handled at the time of manufacturing, specifically, the set member to the mold are one magnetic drive, so that the working process is simplified, and there are manufacturing advantages such as cost reduction.

In the variation movable body for bidet NH1-75,
The three magnetic action parts NH1-18a-18c were separately integrated with the resin-made water discharge piece NH1-76 by insert molding or the like. That is, as shown in FIG. 58, each magnetic action portion is individually embedded in the flange portion NH1-77 of the water discharge piece. Therefore, in this movable body, the rust preventive treatment of the magnetic action part is not required, and there is an advantage in manufacturing to that extent. In addition, the respective magnetic action parts are arranged independently of each other, and are magnetically separated from each other by a water discharge piece made of resin.
That is, a magnetic flux is unlikely to be formed over the adjacent magnetic action part. For this reason, when each electromagnetic coil is excited and a coil acting force is exerted on each magnetic acting portion, the magnetic flux having the magnetic acting portion as a magnetic path does not leak to the adjacent magnetic acting portion. Therefore, the magnetic acting portion can be efficiently attracted, and the attracting force based on the coil acting force does not decrease. As a result, it is only necessary to excite each electromagnetic coil so that a small coil attraction force can be exerted, and it is possible to reduce the size and power consumption of the electromagnetic coil.

In the bidet movable body NH1-80 of another modified example, the three magnetic action parts NH1-18a to 18c are separately arranged and are made magnetically independent by a resin water discharging piece. In common with the bidet movable body NH1-75. In the bidet movable body NH1-80, as shown in FIG. 59, each magnetic action portion has an inner edge NH1-18w.
Flange portion NH1-8 of water discharge piece NH1-81 on upper and lower surfaces
2 are wrapped around and are individually fixedly arranged on the water discharge piece. Like the magnetic driving body NH1-18, each magnetic acting portion is firmly fixed by the anchor effect of the anchor hole NH1-18y. Therefore, even with the movable body of this modified example, the magnetic flux having the magnetic action portion as the magnetic path is generated by the independent arrangement of each magnetic action portion and the magnetic separation through the resin water discharge piece of each magnetic action portion. It can be prevented from leaking to the adjacent magnetic action part. For this reason, by improving the attraction efficiency of the magnetic action portion and avoiding a decrease in the attraction force, not only the movable body of the above-described modified example, but also the same effect as the movable body of the above-described modified example can be exhibited, and the movable body is composed only of the soft magnetic material necessary for attraction. The weight of the bidet movable body NH1-80 can be reduced, and the size and power consumption of the electromagnetic coil can be reduced.

In addition, the following modifications are possible.
For example, in the above-described embodiment, the cleaning area is changed through variable control of the duty ratio Dt at the time of exciting the electromagnetic coil, but the following method may be adopted. In exciting the electromagnetic coil, the applied voltage value to the electromagnetic coil is adjusted by a method such as phase angle control to increase or decrease the coil acting force on the magnetic acting portion, and as described above, the water discharge hole swing angle α is extended. The washing area can be variously adjusted.

Further, in the above-described embodiment, when the washing water flows into the washing water spouting hole of the movable body from below, the movable body receives a constant force from the inflow washing water, and the force from the inflow washing water is fixed. Was not taken into account, but the following can also be performed. This inflow washing water hits the tapered surface of the large-diameter water discharge guide hole on the lower end side of the water discharge hole inclined with the movable body from below, so that the force from the inflow cleaning water acts in a direction to return the inclination of the movable body. I do. Therefore, as the water amount of the inflow cleaning water, that is, the water force set by the water force setting button increases, the force for returning the movable body to the inclination increases. For this reason, when a predetermined washing area, that is, a water discharge hole swing angle α (duty ratio Dt) is set by the spot / wide setting button, if the strength of the water force is used together, the setting is completed by the spot / wide setting button. Is changed in accordance with the set water force. For example, if the water force is set high, the duty ratio Dt already set by the spot / wide setting button is controlled to increase according to the water force high setting, and if the water force is low, the duty ratio Dt is set according to the setting degree. Control to decrease. In this way, even when the water force is set, the movable body and the water discharge hole swing angle α of the water discharge hole can be maintained in the same manner as before the water force setting, and it is possible to prevent a feeling of incongruity due to an inadvertent change in the cleaning area. it can.

Further, the following fine adjustment function at the time of shipment can be provided. There is a possibility that the water discharge hole swing angle α may vary due to the variation of the magnetic acting force due to the electromagnetic coil or the variation of the elastic force of the movable body flange such as rubber or elastomer. Therefore, it is more preferable to provide a function for fine-tuning this (variation absorption function) and fine-tune it at the time of product inspection before product shipment. To briefly describe a specific method, for example, a knob such as a variable resistor is provided on an auxiliary operation unit or the like of the sleeve, and the knob is adjusted. The value of the variable resistor sets a duty value or a reference value of the voltage to the electromagnetic coil. At the time of product shipment inspection, the knob is adjusted so that the water discharge hole deflection angle α becomes a constant reference value under certain conditions. Further, the timing of the adjustment is not limited to the time of the product shipping inspection, may be after the product is mounted, and may be adjusted not only by the manufacturer but also by a maintenance person or user.

Next, another embodiment will be described. Prior to the embodiment, a reference example will be described first. Figure 60

And the flow path switching valve WN2-2 of the washing nozzle WN2-1 is provided from the wave generation unit.
The washing water is guided to the washing nozzle WN2-1 through the nozzle, and the washing water is discharged from the nozzle as described later. These units are connected by upstream and downstream water supply lines across the wave generation unit. That is, the water inlet valve unit and the heat exchange unit are connected by the upstream water supply line WP2-5, and the nozzle device downstream of the wave generation unit is connected by the downstream water supply line WP2-6.

The inlet-side valve unit WP2-1 differs from the inlet-side valve unit WP1-1 in FIG. 4 in that a pressure regulating valve WP2-4 is provided instead of the constant flow valve WP1-9 (see FIG. 4).
For this reason, the cleaning water is adjusted to a predetermined pressure (primary pressure: about 1.0 kgf / cm 2) by the pressure adjusting valve WP2-4, and then is opened from the water inlet side valve unit WP2-1 through the opening of the solenoid valve. It flows into the heat exchange unit TH1-1. Then, as described above in the heat exchange unit, the washing water that has been heated to the set temperature based on the temperature on the inlet / outlet side is supplied to the flow control switching valve WP.
After the flow rate is adjusted by 2-2, the water flows into the wave generation unit and the functional water units WP1-4. Since the generation of functional water by this functional water unit is the same as in the above-described embodiment, description thereof will be omitted. The flow control switching valve WP2-2
May be configured such that the flow rate to the wave generation unit (wash water discharge flow rate) is adjusted by changing the opening ratio of the pipeline leading to the wave generation unit and the pipeline leading to the functional water unit. In this case, the washing water having the difference between the washing water flow rate that has reached the flow control switching valve and the washing water spouting flow rate is sent to the functional water unit, and is spouted from the chamber to the nozzle as described above, and is discharged to the toilet bowl. run down. In other words, the flow rate of the flush water spout is adjusted via the flush water derivation other than the nozzles.

The wave generation unit WP2-3 includes an accumulator WP2-7 and a wave generation device WP from the upstream side.
2-8. As shown in FIG. 61, this accumulator is provided with an upstream water supply line WP upstream of the wave generation device.
2-5, and a damper WP2 disposed in a damper chamber WP2-10 within the housing.
-11 and a spring WP exerting a biasing force on the damper.
2-12. Therefore, the accumulator reduces the water hammer of the upstream water supply pipeline WP2-5 upstream of the wave generation device. Therefore, the effect of the water hammer on the temperature distribution of the cleaning water in the tanks TH1 to TH3 can be reduced, and the temperature of the cleaning water discharged can be stabilized. In this case, the accumulator WP2-7 may be disposed close to or integrally with the wave generation device WP2-8, so that the pulsation generated by the wave generation device propagates upstream as described later. This is preferable from the viewpoint that this can be quickly and effectively avoided. In this case, the accumulator is configured to have only a damper chamber as a mere air chamber without a damper and a spring for energizing the damper, or an air reservoir that intentionally inflates the upstream water supply line partially upward. It can also be formed as

As shown in FIG. 62, the wave generator WP2-8 includes a cylinder W connected to the upstream / downstream water supply line.
A plunger WP2-14 is slidably provided on P2-13. Then, the plunger is moved forward and backward by the excitation control of the electromagnetic coil (pulsation generating coil) WP2-15. The plunger WP2-14 moves downstream from the illustrated original position by the excitation of the pulsation generating coil WP2-15, but receives the urging force of the upstream / downstream springs WP2-16 and WP17 when the coil excitation disappears. Return to the original position. Since the plunger WP2-14 has a check valve WP2-18 formed of a steel ball and a spring therein, when the plunger WP2-14 moves from the original position to the downstream side, the cleaning water in the cylinder is pressurized to supply water to the downstream side. Flush into conduit. On this occasion,
Since the plunger original position is constant, a fixed amount of washing water is sent to the downstream water supply line. After that, when returning to the original position, the flush water flows into the cylinder via the check valve, so the next time the plunger moves downstream, a certain amount of flush water is sent again to the downstream water supply line. become. In addition, when the plunger returns to the original position, the washing water is drawn in the plunger downstream side, that is, in the downstream water supply pipe.
Causes a pulsation in which the pressure periodically fluctuates up and down with the reciprocation of the plunger, and causes the washing water to flow to the downstream water supply pipe in a pulsating flow state.

In this case, the above-described primary-pressure washing water is supplied to the wave generator WP2-8 via the upstream water supply line. Therefore, as described above, the plunger WP2-14
Although the washing water that has flowed into the cylinder via the check valve during the return to the original position does not remain at the primary pressure due to the pressure loss caused by the check valve and the suction of the washing water on the downstream side,
It is sent to the downstream water supply pipeline. When this state is represented by a diagram, as shown in FIG. 63, the cleaning water is supplied from the wave generation device WP2-8 to the downstream water supply line at a pressure pulsated around the primary pressure, and thus the cleaning nozzle WN2-. 1 and discharged to a local area as described later. Moreover, the wave generation device WP2
The flushing water pressure sent downstream from -8 does not become zero due to the flushing water flowing into the cylinder via the check valve when the plunger returns to the original position as described above. The pulsation transition of the washing water pressure is reflected in the transition of the washing water flow rate.

The pulsation cycle MT shown in FIG. 63 is synchronized with the excitation cycle of the pulsation generation coil WP2-15, and can be variously set as described later through the control of changing the excitation cycle. In addition, since only the coil excitation for reciprocating the plunger is required to generate the pulsating flow of the cleaning water, the configuration of the wave generating device can be simplified.

In the reference example, as shown in FIG.
The wave generation device WP2-8 is connected to the heat exchange unit tank TH.
Since it is disposed downstream of 1-3, the pulsating flow of washing water does not pass through a tank that tends to cause pulsation damping because it has a larger diameter than the water supply line. Therefore, pulsating flow of washing water can be fed to the downstream water supply pipe, and thus to the washing nozzle WN2-1, without being affected by pulsation damping by the tank.

Further, when installing the wave generator WP2-8, a so-called anti-vibration rubber was interposed. Therefore,
Due to the vibration damping action of the vibration isolating rubber, the vibration accompanying the generation of pulsation can be suppressed, and the generation of abnormal noise due to the vibration can also be suppressed. In this case, the pulsation generating device is installed on a resin plate (not shown) which has been given a high specific gravity by mixing a powder or a granular material having a high specific gravity such as a metal, and the resin plate is covered with a vibration isolating rubber. It can also be interposed and arranged on the bottom plate of the main body. In this case, the vibration source mass is increased by the sum of the pulsation generating device and the resin plate, so that the vibration caused by the pulsation can be made hard to occur. it can. In order to increase the vibration source mass in this way, instead of installing the pulsation generation device on the resin plate having a high specific gravity as described above, the vibration generation device is attached to a member or unit having a large mass of the local cleaning device. Can also be installed. In this case, since no resin plate is required, there is an advantage in manufacturing such as a reduction in cost due to a reduction in the number of members, and the size of the apparatus can be reduced. Also, if you install a vibration isolating rubber between the wave generator and the resin plate,
FIG. 6 shows the vibration-proof rubber and the vibration-proof rubber on the lower surface of the resin plate.
As shown in FIG. 4, a vibration isolation damper mechanism having two degrees of freedom can be configured. Therefore, the spring constant k effective for vibration reduction
By selecting an anti-vibration rubber so that 1, k2 and damping coefficients c1, c2 can be obtained, a high damping effect can be exerted, and vibration propagation to a toilet seat or the like can be effectively avoided. In addition,
With such vibration suppression, generation of abnormal noise due to vibration can also be effectively suppressed.

The wave generator WP2-8 and the tank T
Unnecessary pulsating pressure is not applied to the tank in combination with the arrangement of the accumulator between H1 and H1-3.
For this reason, an inadvertent rise in the tank internal pressure can be avoided, so that fatigue due to deformation and contraction / expansion of the tank can be avoided.

In the reference example, the following was made in configuring the above-mentioned waterway system. That is, both the upstream water supply line and the downstream water supply line are made of high-hardness flexible piping, and the hardness of the above-mentioned downstream water supply line is made larger in the upstream line. Couplers of the coupler system were used for these pipes and the pipe connection of each unit. Further, the units were arranged close to each other to shorten the length of the water supply pipe between the units. As a result, expansion and contraction, expansion and contraction of the water supply pipe itself are less likely to occur, and the influence of pulsation damping due to this expansion and contraction can be suppressed.
In a state where the pulsation damping is reduced, the pulsating cleaning water can be sent to the cleaning nozzle WN2-1. In particular, since the wave generation device WP2-8 and the flow path switching valve WN2-2 are arranged close to each other, the pulsation damping when the wash water passes through the downstream water supply line between the wave generation device WP2-8 and the downstream water supply line is high. Combined with the flexibility of the flexible piping, it can be suppressed more effectively.

The control system of the local cleaning device of the reference example is shown in FIG.
As shown in the figure, the electronic control unit CT2-1 is mainly configured. This electronic control device, in the same manner as in the above-described embodiment, performs pulsation in addition to electromagnetic valve opening / closing valve control of the water inlet side valve unit, heater energization control of the heat exchange unit, and the like based on inputs of various buttons and sensors. The above-described pulsation frequency control is executed through the excitation control of the generating coil WP2-15. This pulsation frequency control will be described later in detail.

C2 / Nozzle Device NS2-1: Next, the nozzle device NS2-1 of the local cleaning device of the reference example will be described. FIG. 66 is a schematic perspective view showing the nozzle device NS2-1, and FIG. 67 is a schematic sectional view taken along line 67-67 in FIG.

As shown, the nozzle device NS2-1 of this reference example is a nozzle device N of a modification of the above-described embodiment.
It has almost the same configuration as S1-20. That is, the nozzle device NS2-1 is a modified nozzle device NS1-20.
Similarly, on the guide rail portion NS1-21 having a curved shape coinciding with the nozzle advance / retreat trajectory NS1-12 (see FIG. 7),
A similarly curved cleaning nozzle WN2-1 is provided. And the track gripper WN1-2 below the nozzle rear end side
1 grips up and down the right and left rail portions of the guide rail portion NS1-21 and slides along the guide rail portion.
The transmission mechanism NS1-5 advances and retreats along -12. Since the washing nozzle is slidably held by the nozzle holding portion NS1-6 on the toilet bowl portion side (see FIG. 8), the nozzle holding portion and the track holding body are separated from each other. It will be slidably held in several places. In addition, the cleaning nozzle may be formed in a straight conduit shape.

[0266] A grip portion WN2-3 having a slidability with respect to the rail portion and a vibration absorbing function is provided at a location where the guide rail portion is gripped by the track gripper WN1-21. The grip portion having such properties is manufactured using a rubber-based material that has been subjected to a material blending process such as oil impregnation and WAX blending, or a rubber-based material that has undergone a surface treatment such as Teflon coating, halogen treatment, and satin finish. . Therefore, even if the pulsating flow of washing water flows from the wave generation device WP2-8 into the cleaning nozzle as described later, and the vibration due to the pulsating flow occurs in the cleaning nozzle, the vibration is prevented from propagating to other members. it can. For this reason, generation of abnormal noise due to vibration can also be suppressed. In this case, if the rubber-based material that exhibits the slidability and the vibration absorbing function after being subjected to the above-described compounding treatment or surface treatment is disposed on the inner wall of the nozzle holding hole in the nozzle holding portion on the toilet bowl portion side, the vibration described above can be obtained. The effect of preventing propagation and the effect of avoiding the generation of abnormal noise can be enhanced.

In the nozzle device NS2-1 of this reference example,
From the positional relationship between the washing nozzle and the guide rail as described above,
Compact in the width direction. Therefore, the nozzle device and the wave generation device WP2-8 can be arranged closer to each other, so that the effect of suppressing pulsation attenuation in the downstream water supply pipe can be enhanced. When installing this nozzle device, the base NS1-2 (see FIG. 66)
Was disposed on the bottom plate of the main body with an anti-vibration rubber therebetween. Therefore, even if the vibration accompanying the pulsation propagates to the nozzle device, the vibration can be effectively suppressed by the vibration damping rubber and the generation of abnormal noise due to the vibration can be suppressed.

E2 / Washing nozzle WN2-1: Next, the washing nozzle WN2-1 will be described. FIG. 68 is a schematic cross-sectional view of a main part for describing a configuration of a flow path switching valve WN2-2 of the cleaning nozzle, and FIG. 69 is an exploded perspective view of a main part of the flow path switching valve. FIG. 70 shows the nozzle head NH.
FIG. 71 is a plan view showing the head 2-1 in a plan view and partially cutting the periphery of the head, and FIG. 71 is a plan view showing a modification of the nozzle head.

As shown in FIGS. 66 to 68, the flow path switching valve WN2-2 is located at the rear end of the washing nozzle WN2-1, and the pulsating flow of washing water sent from the wave generator WP2-8. The following configuration is provided to switch the water supply destination to each nozzle flow path for cleaning the bottom of the cleaning nozzle, for soft cleaning, and for bidet cleaning.

The flow path switching valve WN2-2 is provided with a casing WN2-4 having a switching mechanism described below. The flow path switching valve is integrated with the cleaning nozzle by welding the casing to the rear end surface of the cylindrical portion WN2-5 of the cleaning nozzle WN2-1. Therefore, it advances and retreats along the track as described above together with the cleaning nozzle.

A stator WN2-6 having a communication hole communicating with each flow path in the nozzle is provided on the casing from the nozzle side.
A rotor WN2-7 that rotates for switching the flow path and selectively opens each communication hole of the stator, a coupling WN2-8 for transmitting rotation to the rotor, and a rotatable coupling. A housing WN2-9 housed in the housing,
Spring WN2- urging rotor toward stator
And 10. As shown in FIG. 69, each communication hole WN2-11 to 13 of the stator is equally opened on the side facing the rotor, and on the nozzle side, the flow path in the nozzle shown in FIG. First nozzle channel WN of the nozzle channel
1-7, second nozzle channel W of the nozzle channel for soft cleaning
N1-8, third nozzle channel WN of bidet cleaning nozzle channel
It is open so as to communicate with each flow path of 1-9. That is, the communication hole is curved in the stator. These communication holes may be arranged alongside the openings of the nozzle flow paths at the rear end of the washing nozzle. In this case, the communication holes may be straight holes. In addition,
The first to third nozzle flow paths WN1-7 to WN9 are:
Until the nozzle head NH2-1 at the tip of the nozzle, the cylindrical portion WN
2-5 are formed in the longitudinal direction.

The rotor WN2-7 has a notch WN2 which can open one of the communication holes equally opened on the upper surface of the stator.
The communication hole is opened by overlapping the notch with the communication hole opening. In this case, the rotor can shield each communication hole by locating the notch between the adjacent communication holes. That is, if the rotor is slightly rotated from the position where the notch is between the adjacent communication hole openings, the washing water can be sent to the above-described respective nozzle flow paths through the communication hole.
In addition, for the convenience of draining (draining) water remaining in the nozzle, the rotor is provided with a notch that can overlap with all the communication hole openings. The communication hole can be opened.

The coupling WN2-8 is provided with a flow path switching valve W
N2-2 is mounted on the rotation shaft of the drive motor WN2-15, and the rotation shaft pin WN2-1 is inserted into the slit WN2-16.
Position 7. In addition, this coupling connects the rotary key WN2-18 to the slit WN2-1 of the rotor WN2-7.
9 is located. Therefore, when the drive motor rotates forward and backward, the rotation is transmitted to the coupling by the rotation shaft pin and to the rotor by the rotation key. Then, since the notch selectively opens one of the communication holes as described above due to the rotation of the rotor, the pulsation from the wave generation device WP2-8 is supplied to the nozzle flow path corresponding to the selected communication hole. Stream wash water is supplied.

In this case, the washing water from the wave generation device WP2-8 is supplied to the downstream side water supply pipe WP2-6 (see FIG. 60) and the connection joint WN2-20 provided on the casing of the flow path switching valve WN2-2. After that, it flows into the flow path switching valve. In connecting the downstream water supply line from the wave generating device to this connection joint, measures such as disposing the wave generation device below the connection joint are taken so that air cannot be trapped in the middle of the downstream water supply line. I made it. For this reason, during the time when the pulsating flow of the washing water reaches the flow path switching valve from the wave generation device, since there is no air pool and the pipe is of high hardness as described above, the pulsation attenuation is further reduced. It can be suppressed effectively. In addition, the only pipe line from which the pulsating flow of the washing water reaches the nozzle device is the downstream water supply pipe line between the wave generation apparatus and the flow path switching valve. Then, a buffer material such as a vibration-proof rubber was disposed at a place where the downstream water supply pipe could come into contact with surrounding members. Specifically, the vibration-proof rubber was attached to the surrounding member side, and the water-proof pipe was wrapped with the vibration-proof rubber. Therefore, coupled with the fact that the downstream water supply pipe is of high hardness as described above,
The pulsation can be suppressed more effectively.

Each member such as the casing of the flow path switching valve WN2-2 is made of polyphenylene sulfide (abbreviated as PP).
S), durability of polyacetal (abbreviation: POM), polybutylene terephthalate (abbreviation: PBT), glass fiber reinforced polybutylene terephthalate (abbreviation: GF / PBT), etc.
It is formed using engineering plastic with high heat resistance. Therefore, the washing water flow path in the flow path switching valve is
Since it functions as a high-strength pipeline, pulsation damping due to expansion and contraction of the pipeline does not occur. When supplying the pulsating flush water from the wave generator WP2-8 to the nozzle flow path, the flow path switching valve is integrated with the cleaning nozzle and there is no piping between them, so that the pulsation is attenuated. Hardly ever happen. Further, when switching the water supply destination as described above, the rotation of the rotor WN2-7 is used, so that the pulsation damping can be reduced more than the flow path switching valve using the elasticity of an elastic body such as a diaphragm. It can be suppressed effectively.

According to the flow path switching valve WN2-2, there are the following advantages. The flow path switching valve is a wave generation device WP2
It is integrated with the cleaning nozzle WN2-1 downstream of -8 instead of -8, and is separated from a wave generation device that can be a vibration source due to generation of a pulsating flow. Therefore, the vibration source can be only the wave generation source. In addition, the flow path switching valve,
It moves forward and backward together with the cleaning nozzle, but the drive motor WN2-1
In No. 5, since the coil winding portion is resin-molded, there is no problem in driving the motor even if the washing water scatters on the drive motor when entering the washing position. Furthermore, since the number of downstream water supply pipes leading to the nozzle device can be reduced to one, it is possible to reduce the degree to which the pipes become a load when the nozzle moves forward and backward. Therefore, the load torque on the nozzle driving motor can be reduced.

The nozzle head NH of the cleaning nozzle WN2-1
Even if it is in 2-1, buttocks spout hole NH for normal ass washing
2-2 and a soft spout hole NH for soft cleaning of the buttocks
2-3 and a bidet spout NH2-4 for bidet cleaning. The nozzle head has a cylindrical portion WN2-
5, a first head passage NH2-5 and a second head passage NH2 formed inside the nozzle head in a watertight manner.
-6, the third head flow path NH2-7, and the first nozzle flow path WN1-7 and the second nozzle flow path WN of the cleaning nozzle, respectively.
1-8, connected to the third nozzle channel WN1-9. As shown in the drawing, these nozzle flow paths reach the above-described water discharge holes on the upper surface of the nozzle head. Therefore, the flow path switching valve WN
When 2-2 (see FIG. 66) switches the supply destination of the cleaning water to any of the first to third nozzle channels WN1-7 to 9 at the rear end of the nozzle, the cleaning water is switched. Water is discharged from each of the water discharge holes via the nozzle flow path and the head flow path. In this case, the pulsating flush water is supplied from the wave generation device WP2-8, so that pulsating flush water is discharged from each water discharge hole.

In this case, in each of the water discharge holes NH2-2 to NH4 of the nozzle head NH2-1, the bottom water discharge hole has the smallest diameter, and the bidet water discharge hole and the soft water discharge hole have a smaller diameter than this water discharge hole. Has been enlarged. For this reason, the water pressure setting button SWh of the remote control device RC1-1 (see FIG. 2).
In a situation where the water force is set to be constant by u and SWhd, as described in the previous embodiment, the water discharge speed of the wash water from each water discharge hole is the fastest in the bottom water discharge hole and the bidet water discharge speed. It is slower than the butt spout in the hole and the soft spout. Then, in the soft cleaning with a low water discharge speed, the washing feeling received from the water discharge is made at least softer by the low water discharge speed than in the case of the normal butt cleaning. Note that the bidet water discharge hole and the soft water discharge hole are not limited to a single hole as shown in the figure, and a plurality of small-diameter fine holes are arranged as shown in FIG. It can also be formed as a water discharge hole. In this case, if the total area of the water discharge holes, which is the sum of the areas of the plurality of pores, is equal to or more than the area of the bottom water discharge holes, the water discharge becomes softer as a whole of the pores than in the case of the bottom cleaning.

Next, taking the ass washing as an example, the state of spouting of washing water by the local washing apparatus of this reference example will be described. FIG. 72 is an explanatory diagram illustrating the state of excitation of the pulsation generating coil WP2-15 of the wave generation device WP2-8 that generates a pulsation at the time of flush water discharge. FIG. FIG. 74 is a timing chart showing the amount of water and the flow velocity of the nozzle head NH2-1.
It is explanatory drawing which illustrates typically the state of water discharge of wash water from the tail water discharge hole NH2-2.

The electronic control unit CT2-1 generates a pulse signal when exciting the pulsation generating coil WP2-15 to generate pulsation in the wave generation device WP2-8. Then, the pulse signal is output to a switching transistor (not shown) connected to the pulsation generating coil and turned on. Therefore, the pulsation generating coil is repeatedly excited by turning on / off the switching transistor according to the pulse signal, and as described above, the plunger WP2
-14 is reciprocated periodically. As a result, wash water is supplied from the wave generation device WP2-8 to each of the water discharge holes of the nozzle head in a pulsating flow state in which the pressure periodically fluctuates up and down, and the pulsating flow of the wash water is discharged from each of the water discharge holes. Is done. At this time, the electronic control unit variably controls the frequency of the pulse signal in a predetermined frequency range and controls the duty ratio of the on / off of the coil excitation pulse. Thereby, various pulsations can be caused. In this case, a pressure sensor for detecting the pressure of the pulsation caused by the wave generating device may be provided on the downstream side immediately after the wave generating device, and the duty ratio control may be fed back by the detection value of the sensor. The position of the sensor is not limited as long as it can reflect the pulsating pressure. For example, it may be provided in the vicinity of the cleaning nozzle, or may be provided in the vicinity or substantially integrally by using the mechanism of the wave generation device.

As shown in FIG. 72, the pulsation cycle MT shown in FIG. 63 is set to a cycle T1, and the ON time of the pulse signal is set to t1.
Then, the duty ratio is (t1 / T1) × 100
(%). When the pressure pulsation as shown in FIG. 63 occurs, the amount of the washing water decreases to a value represented by the duty ratio as compared with the continuous flow. As shown in FIG. 73, the amount of water of such a pulsating flow increases and decreases in the range from the maximum flow rate Qmax to the minimum flow rate Qmin, and the flow rate also increases and decreases in the range from the maximum flow rate Vmax to the minimum flow rate Vmin. In FIG. 73, the reason why the minimum flow rate Qmin and the minimum flow velocity Vmin are not zero is that the pulsation pressure by the wave generator WP2-8 is not zero even at its minimum as described above.

When the continuous flow of the wash water is discharged from the water discharge hole (for example, the tail water discharge hole NH2-2) as in the related art, the wash water from the water discharge hole is continuously discharged as shown in FIG. In contrast, when the pulsating flow of the washing water is discharged as shown in FIG. 74 (B), the washing water is discharged in a discrete or water mass state as shown in FIG. 74 (B). Is done. As described above, when the washing water pulsated by the wave generation device WP2-8 is jetted from the water discharge hole of the washing nozzle,
The reason for the discrete or water mass state will be described with reference to FIGS. 73 and 75.

FIG. 75 is an explanatory view for explaining a process in which, when the pulsating flow of cleaning water is discharged from the water discharge hole, the discharged cleaning water is amplified into a pulsating flow. As shown in FIG. 73 (A), when the amount of washing water is pulsated by the wave generation device WP2-8, the flow velocity V is similarly changed to be pulsating. That is, the amount of the flushing water discharged is the maximum flow rate Qmax.
Then, the flow velocity also reaches the maximum velocity Vmax, and the instantaneous flow velocity and flow rate fluctuate with time. Further, each part of the pulsating flow of the washing water in FIG. 73 is represented by Wp1, Wp2, Wp3, Wp.
4, Wp5, the amount of each part is Wp1 (= Wp5).
5) <Wp2 (= Wp4) <Wp3, and the respective flow rates also satisfy V1 (= V5) <V2 (= V4) <V3. Therefore, as soon as the state shifts from (A) to (C) in FIG. 75 immediately after the water discharge, Wp3 has a higher speed than Wp2, so that Wp3 merges with Wp2 and further merges with Wp1 to form a large body of water. As described above, when the maximum flow velocity Wp3 is sequentially merged with the preceding Wp2 and Wp1, a large lump is formed, and the water reaches the local part of the human body (cleaning surface). As described above, when the washing water hits a local body part, the washing water is in a state of a water mass having a large collision energy (washing strength). This flow velocity V3 is the maximum flow velocity Vma shown in FIG.
Since it is x, the wash water spouted by the pulsating flow is spouted from the spout hole in a spout form in which the state of the combined water mass appears at each pulsation cycle MT. In addition, since such a phenomenon occurs in the pulsation cycle, the water mass that has passed through the coalescence of the maximum flow velocity Wp3 as described above repeatedly appears, and the water mass at a certain water discharge timing and the water mass at the next water discharge timing merge. Will be moved (spouted) at substantially the same speed (maximum speed) as the water mass that has passed.

Next, the difference in the cleaning intensity between the case where the washing water is ejected as a continuous flow from the tail water discharge port NH2-2 and the case where the washing water is ejected as a pulsating flow will be described. The pulsating flow has twice or more the cleaning intensity with the same amount of water as compared with the conventional continuous flow. This is considered as the following reason. The energy E when the washing water having the mass m collides with the wall surface at the speed V is represented by the equation (1). E = (1/2) mV ² (1) Further, the force at the time of collision with the wall surface is represented by f, and the time required for the washing water flow at the speed V to be reduced to 0 and disappear is Δ.
Assuming that t, the energy E is represented by the impulse by equation (2), and the force at that time is represented by equation (3), where α is the deceleration. E = fΔt (2) f = mα (3) FIG. 76 is an explanatory diagram illustrating a state in which the cleaning water stream collides with the wall surface. In FIG. 76, the water masses are W1, W2, and W3.
Assuming the three modes, the cleaning strength of the cleaning water flow in each of these modes will be examined. Here, the water mass W1 has a long form with a cross-sectional area S1, and the water mass W2
Is a form in which the sectional area S2 is twice as long as S1 and is short, and the water body W3 is a form having a sectional area of S1 and a half length of the water body W1. In these embodiments, the water mass W1 corresponds to a continuous flow, and the water mass W3 corresponds to a pulsating flow. At this time, the water mass W
Time Δ until water 1 and water body W2 collide with the wall and disappear.
t1 and Δt2 satisfy Δt1> Δt2. This means
Equation (3) indicates that the deceleration α is large and the water mass disappears with a large force in a short time, and the force f1 of the water mass W1 and the force f2 of the water mass W2 satisfy f1 <f2. Therefore, it can be understood that the force f2 applied to the human body local part is larger in the water body W2 that disappears in a short time than in the continuous water body W1. For this reason, the mass of water W3 corresponding to the pulsating flow has a mass of m / 2 as compared with the mass of water W1, but the force f3 does not decrease much as compared with f1. Therefore, when jetted as a pulsating flow, the amount of water can be made smaller than that of the continuous flow, and the force at the time of colliding with the human body local part does not decrease so much. Can be removed.

Next, the relationship between the washing intensity, which is an index indicating the feeling of washing of a human body part, and the feeling of washing will be described. FIG. 77 is an explanatory diagram illustrating a state in which the pressure sensor plate Ps is installed at a predetermined distance La so as to face the buttocks discharge hole NH2-2. The predetermined distance La is set at a position where the human body part is cleaned. The pressure sensor plate Ps is a sensor that includes detection units in a two-dimensional matrix and outputs the detection values of each detection unit independently. Using such an apparatus, the peak value of the pressure output from each detection unit when the washing water was spouted from the tail spout hole NH2-2 of the washing nozzle WN2-1 was measured. FIG. 78 shows the result. FIG. 78 is an explanatory diagram three-dimensionally expressing the position on the pressure sensor plate Ps and the peak value of the pressure, and the XY plane is the pressure sensor plate Ps.
The position of s, that is, the position of the object to be detected, is shown, and the Z axis represents the peak value of the pressure at each position. FIG. 78 (A)
Indicates that the cleaning water reaching the water discharge hole has a flow rate of 1.1 L / min. FIG. 78 (B) shows the measurement results at the time of continuous flow of 0.5 L / min. 5 shows the measurement results at the time of the pulsating flow. In FIG. 78, the cleaning intensity, which is a factor that affects the feeling of cleaning, is represented by the peak value of the pressure, while the feeling of volume is represented by the volume of the mountain, which is the overall pressure distribution.

When these are compared, the peak value of the pressure in the pulsating flow of FIG. 78 (B) greatly increases, although the amount of washing water is reduced by half compared to the continuous flow in FIG. 12 (A). ing. This indicates that the washing pressure on the water body is large, that is, the washing strength is large.
FIG. 79 is a timing chart showing a detection signal detected from one of the detection units. FIG.
FIG. 79 (B) shows a pulsating flow. It can be seen that the pulsating flow has a higher peak value and a higher intensity than the continuous flow. Also, the pulsating flow of FIG. 78 (B) is much larger in the volume of the peak, which is the overall pressure distribution, than the continuous flow of FIG. 78 (A). As described above, the pulsating flow has an extremely large volume as compared with the continuous flow, and it can be understood that the pulsating flow has excellent detergency when the sensual element of the cleaning feeling is embodied in a numerical value.

FIG. 80 shows the result of examining the actual cleaning amount by such a pulsating flow in comparison with a continuous flow. FIG.
It is a graph showing the relationship between the average amount of water discharged and the amount of cleaning, that is, when removing dirt attached to the human body part with cleaning water,
It shows the required average water discharge. As can be seen from FIG. 80, in order to remove the dirt of the cleaning amount D1 adhered to the human body part, it was found that the pulsating flow had a water amount of about 1/4 that of the conventional product which can only discharge the continuous flow of cleaning water. . As described above, by the method of discharging the pulsating flow of cleaning water from the water discharge hole, the cleaning strength and the user's feeling of cleaning can be dramatically increased.

Further, when the pulsating flow of the washing water is spouted, the washing intensity is increased and the stimulation to the human body part is increased. This can be explained as follows as in the above-described embodiment. When a stimulus that can be sensed at the same part of the human epidermis (in this reference example, a stimulus due to collision of water masses W1, W2, and W3 shown in FIG. 76) is intentionally repeatedly applied, the repetition interval (pulsation in this reference example) is used. Period (MT) is long and the repetition frequency is low,
The human perceives this repeated stimulus as a vibration stimulus each time. On the other hand, if the repetition interval is short and the repetition frequency is high, a person cannot perceive this intentionally repeated stimulus as a vibration stimulus but perceives it as a continuous stimulus.
In other words, there is a dead band frequency that cannot be sensed as a vibration stimulus for a repetitive stimulus to the human epidermis, and this dead band frequency is a repetition frequency of about 5 Hz or more, as in the case of the above embodiment. Therefore, in performing the intentional repetitive water discharge of the pulsating flow of the wash water, the higher the repetition frequency, the more difficult it is to follow the perception of the vibration based on the intentional repetitive water discharge. And
If this repetition frequency is about 10 Hz or more, most people who have a normal perception will hardly be able to perceive the vibration due to intentional repeated water discharge. Therefore, it becomes difficult to recognize the water discharge mode (washing water of pulsating flow) that the water is intentionally repeated water discharge. In this reference example, the user who receives the collision of the water mass shown in FIG. Most people cannot perceive the impact of this body of water as intermittent, but can make it feel as if it is a continuous flow of wash water.

The following is a description with reference to the drawings. FIG. 81 is an explanatory view for explaining the reason why the cleaning intensity varies depending on the increase and decrease of the frequency. FIG. 81 (A) is determined by this period because the pulsation period MT is large even with the same amount of cleaning water than FIG. 81 (B). This shows a state where the pulsation frequency fmt (= 1 / MT) is small. In FIG. 81 (A) and FIG. 81 (B), the size can be as large or small as the above-mentioned water mass uniting depending on the length of the cycle. Therefore, in the case of FIG. 81A in which the pulsation cycle MT is large and the pulsation frequency is small, the mass of the water mass in one collision increases, the collision energy increases, and the human body is strongly stimulated. That is, in the case of FIG.
The human body receives a large stimulus at once and feels a strong stimulus.
Further, as shown in FIG. 81 (A), when the pulsation frequency fmt falls below the above-described dead band frequency or becomes a frequency close to this frequency, the human body repeatedly receives a strong stimulus while sensing the stimulus in each case. feel. On the other hand, as shown in FIG. 81 (B), if the pulsation frequency fmt is large and is within the above-mentioned dead band frequency, a small stimulus is received as a continuous stimulus as described above, so that the stimulus is not felt much. From this, even with the same amount of water,
The higher the frequency and the larger the body of water, the stronger the stimulus (cleaning intensity) to the human body. FIG. 82 is a graph showing the relationship between the pulsation frequency and the washing intensity of the pulsating flow and the discomfort caused by the stimulation of the human body local part. When the frequency exceeds 5 Hz, the human skin approaches a continuous flow and can be felt as soft washing, and when the frequency exceeds about 30 Hz, it is almost indistinguishable from the continuous flow. Therefore, the frequency of the pulsation flow is preferably 5 Hz or more. Further, considering that the frequency of the commercial power supply is used as it is for the excitation control of the pulsation generation coil WP2-15 of the wave generation device WP2-8, 50 to 60 Hz Is set as the upper limit, the configuration for control can be simplified.

From the viewpoint of the dead band frequency, even in the reference example, the excitation cycle of the pulsation generating coil WP2-15, that is, the pulsation cycle MT is set so that the pulsation frequency ftm (= 1 / MT) is about 5 Hz or more. Variable control so that
The stimulus to the local human body by the water body is sensed as a continuous stimulus. In other words, despite the fact that the washing water volume is reduced only by intermittently ejecting the washing water mass to the washing location of the human body part at the pulsation cycle MT, the user is continuously provided with the washing spot. It is possible to give a feeling of washing as if the washing water is being spouted. Therefore, even in this reference example, the flow rate of the washing water is controlled by the flow control switching valve WP2-
2 to about 500 cc / min.
Since the cleaning ability and the feeling of cleaning can be improved, it is only necessary to discharge cleaning water at the maximum flow rate. In other words, it is possible to give the user the feeling of receiving continuous water spouting while improving the effectiveness of water saving.

Even if the pulsation frequency ftm is set to the above-mentioned dead band frequency, it can be said that the sense of continuous water discharge from continuous water discharge of the wash water tends to fade as the pulsation frequency ftm decreases. Therefore, the pulsation frequency ftm can be intentionally lowered within the above range to give the user a slight intermittent feeling of washing (stimulation).

Further, pulsation frequency control and duty ratio control of coil excitation can be performed as follows. FIG.
FIG. 84 is an explanatory diagram illustrating a control example in which the pulsating frequency in the pulsating flow of the washing water is made different between the butt cleaning and the bidet cleaning. FIG. 84 is an explanatory diagram illustrating a control example of the pulsating frequency ftm and the duty ratio Dtm. is there.

As shown in FIG. 83, the pulsation periods MTA and MTV for the ass washing and the soft / bidet washing are set to be large and small, and the respective pulsation frequencies ftm can be made different. In addition, the pulsation frequency ftmA at the time of ass washing was set lower than the pulsation frequency ftmV at the time of soft / bidder washing. In this case, both frequencies are in the above-mentioned dead band frequency range. For example, by changing the frequency such as 50 Hz for butt cleaning, 60 Hz for soft cleaning, and 70 Hz for bidet cleaning, as described below, bidet cleaning or the like can be a cleaning form with less water than butt cleaning. May be set to the frequency.

By the frequency control according to the object to be cleaned as shown in FIG. 83, as described with reference to FIG. 81, at the time of cleaning the buttocks, a water discharge form similar to FIG. 81 (A) is obtained.
It becomes a washing that receives a sufficient stimulus continuously,
A hard washing feeling can be obtained. Also, soft
At the time of bidet cleaning, the water is discharged as shown in FIG. 81 (B), so that the cleaning is such that a relatively weak stimulus is continuously received, and a soft cleaning feeling can be obtained. In particular, in the soft bidet cleaning, the pulsation frequency ftm is increased to prevent an intermittent stimulus feeling, so that the soft cleaning feeling can be made more continuous. Moreover, in achieving such various washing feelings, the flow rate can be reduced as described above.

Further, as shown by a dotted line or a dashed line in the drawing, the pulsation frequency ftm is set to be the same for each cleaning, and the duty ratio Dtm can be changed and controlled for each cleaning. The duty ratio Dtm is the coil exciting force, that is, the plunger WP2- in the wave generator WP2-8.
Since the moving speed and the moving amount are determined, the amplitude of the pulsation can be controlled to increase or decrease. Therefore, the washing water amount and the flow velocity shown in FIG. 73 can be controlled according to the duty ratio Dtm. As a result, in each washing, the mass of the water mass shown in FIG. 81 can be changed and controlled, and the intensity of the stimulus and the adjustment of the washing power can be adjusted while having a hard and soft washing feeling. In addition, the strength of the water can be adjusted based on the change in the flow velocity. In other words, since the user's desired washing feeling and water force can be secured by the duty ratio control and the frequency control of the pulsating flow, the amount of washing water can be significantly reduced as described above. In addition, both the duty ratio control and the frequency control
Since it is unrelated to the flow rate adjustment by the flow control valve, the water pressure adjustment that cannot be adjusted by the flow rate adjustment by the flow control valve can be realized through the above two controls. That is, the flow rate adjustment of the flow regulating valve can be complemented by the duty ratio control and the frequency control. Fine adjustment of the water force and the like can be performed by using both the adjustment of the water force and the like through the flow rate adjustment by the flow regulating valve and the adjustment of the water force and the like through the above two controls.

As shown in FIG. 84, the pulsation frequency ftm can be controlled, or the pulsation frequency ftm and the duty ratio Dtm can be controlled simultaneously. That is, as shown in FIG. 84 (a), each cleaning period TA, TB, TC.
In step (1), the duty ratio Dtm is set to the value Dtm, and the pulsation frequency ftm is controlled to increase or decrease in each cleaning period. For example, as shown, the pulsation frequency ftm is set to ftmS, ftmM, ftmL (ftmS <ftmM <
ftmL). Or 2
The increase / decrease control may be performed stepwise, four or more steps, or steplessly. In this way, it is possible to achieve a change in the cleaning sensation of the hardware and the software for each cleaning period and a change in the stimulus sensation, thereby making it possible to diversify the cleaning sensation. Further, if the frequency is different, since the continuous interval of the collision of the water mass is different, the strength of the water obtained by the collision of the water mass can be adjusted by the frequency control. Moreover, since the frequency control is not related to the flow rate adjustment by the flow control valve, the water pressure adjustment that cannot be adjusted by the flow control by the flow control valve can be realized through the frequency control.
That is, the flow control of the flow control valve can be complemented by the frequency control. And by the combination of the adjustment of the water force etc. through the flow control by the flow control valve and the adjustment of the water force etc. through the frequency control
It is possible to make fine adjustments of the water force and the like.

In this case, each cleaning period may have the same time interval or different time intervals for each cleaning period. In addition, when different time intervals are used, the time intervals may change regularly or irregularly. For example, the time interval and tS, tM, tL (tS <tM
<TL), tS → tM → tL → tS → tM ·
・ ・ It may change regularly like tL → tS → t
It may change irregularly as S → tM → tL → tM. It should be noted that such an irregular time interval change can be achieved by loading a random number generation program and determining each time interval according to the generated random number.

As shown in FIG. 84 (b), the duty ratio Dtm is increased or decreased in each of the cleaning periods TA, TB, TC,. For example, as shown, the duty ratio Dtm is set to DtmS, Dtmm, DtM.
mL (DtmS <Dtmm <DtmL). Alternatively, increase / decrease control may be performed in two steps, four or more steps, or steplessly. In addition, the pulsation frequency f
tm is controlled to increase or decrease for each cleaning period as described above.
In this case, the washing feeling can be further diversified. Even in this case, each cleaning period may be set to the same time interval, or may be changed regularly or irregularly.

F2 / Washing operation: Next, the washing operation performed by the local cleaning apparatus of the reference example having the above-described configuration will be described. FIG. 85 is a time chart showing the cleaning operation of the local cleaning device of this reference example.

As shown, when the user sits on the toilet seat KS1-3 (see FIG. 1) and the seating sensor SS10 (see FIG. 65) is turned on, the main cleaning unit receives this ON signal, and , Solenoid valve W of inlet side valve unit WP1-1
P1-10 (see FIG. 60) is controlled to open. As a result, the supply of the cleaning water into the apparatus is started, so that the heater TH1-2 is fully energized for preliminary heating of the cleaning water prior to the cleaning, and the supply destination of the cleaning water is set to the flow control switching valve. WP
At 2-2, the function water unit WP1-4 is switched. Therefore, functional water (free chlorine solution) from the functional water unit is discharged to the nozzle head NH2-1 (see FIG. 8), and the nozzle head is sterilized and cleaned. In this manner, the water supply, hot water supply, and functional water spouting performed immediately after the seating is performed after a predetermined time has elapsed since the sensor was turned on, or when the water discharge temperature sensor SS16b has reached a predetermined temperature (for example, a temperature that is about 2 to 3 degrees lower than the hot water temperature during washing). Stopped when detected. That is, the solenoid valve is closed, the flow control switching valve is switched off, the heater power is reduced (for example, about 30% of full power), and the operation of the cleaning button is awaited thereafter. As described above, since the heater is fully energized for a short time after seating and then the energization is reduced, the washing water is preliminarily heated and the temperature is maintained, so that rapid energization control of the heater is not required during the subsequent washing. In addition, as described above, in the present reference example, since the effect of reducing the flow rate of the cleaning water is high, power can be saved when the heater is energized.

Thereafter, when the washing button, for example, the buttocks washing button SWb (see FIG. 2) is turned on, the solenoid valve WP1-
The valve 10 is controlled to open to supply water for washing the tail, and the heater TH1-2 is fully energized. The heater is
Full energization is continued until the stop button SWa is operated. The closing of the solenoid valve will be described later.

By opening the solenoid valve, pre-nozzle cleaning for self-cleaning the nozzle head is performed prior to local cleaning. That is, following the opening of the solenoid valve, the cleaning nozzle WN2
The water supply destination of the washing water at -1 is switched from the flow path switching valve WN2-2 to the bottom flow path, and then the cleaning water supply destination is set to the cleaning nozzle side by the flow control switching valve WP2-2, and the flow rate at that time is adjusted. Set. As a result, the adjusted flow rate of the washing water is sent to the washing nozzle at the standby position, and the tail water outlet NH2-2.
, The nozzle head is washed by the rebound water in the chamber NS1-14 (see FIGS. 8 and 10). Due to the water flow in the pre-nozzle cleaning, the cleaning water that has already been heated to an appropriate temperature by the full energization of the heater is distributed to the pipeline leading to the nozzle head. For this reason, from the beginning of the main cleaning, which will be described later, the cleaning water at an appropriate temperature can be discharged to a local portion, and the discharge of the low-temperature cleaning water does not cause discomfort. Further, following the flow path switching of the flow path switching valve downstream of the flow control switching valve, the water supply destination of the flow control switching valve and the flow rate setting are performed. Therefore, since the flow path switching valve can be driven in a state close to a no-load state where the water pressure of the washing water is hardly applied, it is preferable that the drive motor is not overloaded. It should be noted that even during the pre-nozzle cleaning, it is also possible to drive the wave generation device WP2-8 to self-clean the nozzle head with pulsating cleaning water. In this case, the pulsation frequency ftm of the coil may be inside the dead zone or outside the dead zone.

[0303] The nozzle pre-cleaning is stopped at a point in time after a predetermined time has elapsed. That is, as shown in the figure, first, the flow control switching valve on the upstream side is switched to the functional water unit side so that the cleaning water does not flow toward the cleaning nozzle. After that, the flow path switching valve is stopped, and the pre-nozzle cleaning is stopped. As described above, even when the pre-nozzle cleaning is stopped, the flow path switching valve can be driven in a state close to no load, so that the drive motor is preferably not overloaded.

Following the pre-nozzle cleaning, the nozzle drive motors NS1-4 are controlled to rotate in the normal direction to control the cleaning nozzle WN.
2-1 is advanced from the standby position to the buttocks washing position. Even during this nozzle advance, the solenoid valve is in the open state, and the flow control switching valve uses the functional water unit as the water supply destination, so that the functional water is discharged from the chamber. Therefore, the functional water can sterilize and clean the cylindrical portion of the cleaning nozzle. In the operation up to the nozzle advance, only the switching destination of the flow path switching valve and the advance destination of the cleaning nozzle (the bidet cleaning position in the case of a bidet) differ depending on the operated cleaning button. The same applies to the bidet cleaning button.

When the advance of the cleaning nozzle to the cleaning position is completed in this manner, the main cleaning of the local part (the butt cleaning, the soft cleaning,
Is performed according to the operation button. As shown in the figure, in the butt washing, the following soft start is performed in order to start washing water spouting of the pulsating flow from the butt spout NH2-2. First, the flow path switching valve WN2-2 is switched to the butt flow path, and then the washing water supply destination is set to the washing nozzle side by the flow control switching valve WP2-2, and the flow rate at that time corresponds to the set water force that has been set. Adjust gradually from zero up to the specified flow rate. It should be noted that the flow rate corresponding to the set water force may be gradually increased from a flow rate smaller than the flow rate corresponding to the set water force by a predetermined amount to the flow rate corresponding to the set water force.

In this soft start, the wave generator W
The generation of the pulsating flow by P2-8 also starts. That is, the pulse signal is output to repeatedly excite the pulsation generating coil WP2-15, and the plunger WP2-14 is reciprocated. Thereby, a pulsating flow is generated as described above. In the case of bottom cleaning, coil excitation is repeated at a pulsation frequency ftm lower than that of bidet / soft cleaning as shown in FIG.
Even in this coil excitation, the duty ratio Dtm of the pulse signal is gradually increased so as to gradually approach the duty ratio corresponding to the set water force that has been set. By such a soft start, even when the set water force is large, the water discharge amount is small, and the water can be gradually discharged from the soft water discharge, which is a pulsating flow based on the small duty ratio Dtm, to the set water force. It is preferable because it does not cause discomfort or discomfort. When such a soft start is completed, the water discharge at the set water force is performed by the pulsating flow of the cleaning water, and the process proceeds to the main cleaning. In this main cleaning, if the water force is changed and set thereafter, the flow rate is adjusted by the flow control switching valve or the pulsation flow control (duty ratio control, pulsation control) by the wave generation device WP2-8 so that the water force is changed. Frequency control).

In general, when adjusting the flow rate of a low flow rate of washing water, fine adjustment of the flow rate lacks the reliability of the adjustment accuracy. This is one of the reasons that the flow rate cannot be reduced with the conventional local cleaning device in which the water force is adjusted by adjusting the flow rate. However, in the local cleaning device of this reference example, since the water pressure can be adjusted as described above through the pulsating flow control (duty ratio control, pulsating frequency control), there is an advantage that the water pressure can be adjusted while the flow rate of the cleaning water is reduced. is there. Therefore, in the local cleaning device of the reference example, when a large change is set from a water force close to the minimum water force to a water force close to the maximum water force, the flow rate adjustment and the pulsation adjustment are performed in combination, and in other cases, The pulsating flow control is used to adjust the water force. That is, the degree of change in the water force is read from the operating states of the water force strength setting buttons SWhu, SWhd, and pulsation flow control (duty ratio control, pulsation frequency control) is performed according to the result. Specifically, if the water pressure is set to be strong, the duty ratio Dtm is increased or the pulsation frequency ftm is controlled.
Is reduced, or both controls are used together.
The low water setting is the opposite. At this time, the wave generator WP
The actual flow rate of the washing water reaching 2-8 is detected by a flow rate sensor (not shown), and the pulsation flow control (duty ratio control, pulsation frequency control) is performed based on the detected flow rate and the set amount of water pressure change. The water pressure can be adjusted. in this case,
The pressure sensor may be used as a flow sensor, or the flow may be indirectly detected by a signal from a switch or the like involved in setting the flow. In addition to the configuration in which the flow rate sensor is arranged upstream of the wave generation device, the flow rate sensor can be placed anywhere as long as it can detect the amount of washing water, and if it is arranged according to the layout of each unit, the product can be made more compact. Can be planned.

The main cleaning is completed as follows by operating the stop button, and thereafter, nozzle retreat and post-nozzle cleaning are performed. That is, when the stop button is operated, the button O
In response to the N signal, the flow control switching valve WP2-2 is first switched to the functional water unit side in order to stop the tail flushing and spouting from the nozzle, and then the water stop of the flow path switching valve WN2-2 and the coil excitation are performed. The output of the pulse signal is stopped and the energization of the heater is reduced. This heater power reduction is maintained until the seating sensor is turned off. Therefore, the temperature of the washing water does not drop carelessly until the sensor is turned off, and is kept at the above-mentioned temperature slightly lower than the appropriate temperature. For this reason,
If local washing is repeated while sitting on the toilet seat,
This is preferable because the washing water can be quickly warmed to an appropriate temperature. Also, at the time of stoppage of the tail-washing and spouting, the flow control switching valve and the flow path switching valve are driven in this order, and the flow path switching valve can be driven in a state close to a no-load state. This is preferable because it is not applied. In addition, the above-mentioned main cleaning (assembly main cleaning) is performed when the user separates from the toilet seat and the seating sensor is turned off before the stop button is operated, or when the assembler is softened during ass cleaning.
The operation is similarly ended when each of the wash buttons of the bidet is operated.

When the flow path switching valve WN2-2 stops running, the nozzle drive motor NS1-4 is controlled to rotate in the reverse direction, and the washing nozzle WN2-1 is retracted and returned to the standby position. When the nozzle retracts, the solenoid valve is in the open state, and the flow control switching valve WP
In 2-2, the water supply destination is a functional water unit, so the functional water is discharged from the chamber. Therefore, the tubular portion of the cleaning nozzle can be sterilized and cleaned by the functional water even when the nozzle is retracted.

When the cleaning nozzle returns to the standby position, the flow switching valve WN2-2 is switched to the bottom flow path in order to start post-nozzle cleaning, and then the cleaning water supply destination is cleaned by the flow control switching valve WP2-2. At the same time as the nozzle side, the flow rate at that time is set. As a result, the adjusted flow rate of the washing water is sent to the washing nozzle at the standby position, and the tail water outlet NH2-2.
, The nozzle head is washed by the rebound water in the chamber NS1-14 (see FIGS. 8 and 10). By the flow of water in the post-nozzle cleaning, the functional water applied to the nozzle head when the nozzle is retracted is washed away. Even in this post-nozzle cleaning, the flow control switching valve and the flow path switching valve can be driven in this order, and the flow path switching valve can be driven in a state close to no load. Is preferred.

When this post-nozzle cleaning is performed for a predetermined time,
To prepare for the next and subsequent local cleaning, the solenoid valve WP1-10
Is closed to stop the supply of the washing water to the local washing device. Thereafter, the cleaning water remaining in the water supply pipe downstream of the flow control valve, the flow path switching valve downstream, and the cleaning nozzle is discharged. That is, in response to the closing of the electromagnetic valve, the pulsation generating coil WP2-15 of the wave generating device WP2-8 is repeatedly excited with a small duty ratio Dtm, and the plunger WP2
-14 is reciprocated. In this case, the pulsation frequency ftm may be a low frequency. When the plunger is reciprocating in this way, the wave generating device is not supplied with cleaning water,
By the reciprocating motion of the plunger, the washing water on the upstream side is sucked into the cylinder, and the sucked washing water is sent out. Therefore, the washing water remaining in the downstream water supply pipe or the like is gradually sent downstream by the washing water sent out by the plunger, and the switching flow path of the flow path switching valve (in this case, the ass flow path) After that, the water is discharged to the toilet bowl from the tail water discharge hole of the nozzle at the standby position. When the discharge of the remaining washing water is completed in this manner, a series of the butt washing operation is completed by switching the flow control valve to the functional water unit side and stopping the water of the flow path switching valve. In the operation after the nozzle retreat, only the switching destination of the flow path switching valve and the advance destination of the cleaning nozzle (the bidet cleaning position in the case of a bidet) differ according to the operated cleaning button. The same is true for the bidet cleaning button.

[0312] In the present reference example, the discharge of the remaining washing water using the wave generator WP2-8 was completed as follows.

When the plunger WP2-14 is moved by energizing the pulsation generating coil WP2-15 of the wave generator WP2-8 to move the plunger WP2-14, a back electromotive force is generated in the coil with the movement of the plunger, and the energizing current is reduced. The so-called bottom phenomenon, which once decreases, occurs. Since this bottom phenomenon appears as a waveform of the current flowing through the coil, there is a correlation between the current waveform and the movement of the plunger. By the way, considering the situation where the pulsation generating coil is excited when the above-mentioned residual cleaning water is discharged, before and after the residual cleaning water is completely discharged, the plunger moves in a state where there is the cleaning water in the plunger cylinder. Then, the plunger moves under the empty condition where there is no washing water. Since the washing water in the cylinder acts as a movement resistance of the plunger, if the coil excitation is performed under the same condition (in this reference example, the same duty ratio Dtm), the plunger is more exposed under the condition where there is no washing water. Moves fast. Therefore, when the plunger moves under the condition that there is washing water in the cylinder to the plunger under the condition that there is no washing water, that is, when the remaining washing water is completely discharged, the bottom phenomenon appears. The situation changes. Therefore, in the local cleaning device of this embodiment, the bottom phenomenon is detected by the bottom detection circuit CT2-2 (see FIG. 65) to detect the completion of the discharge of the remaining cleaning water, and the functional water of the flow control valve is detected as described above. After switching to the unit side and stopping the water of the flow path switching valve, a series of butt washing operations is completed.

FIG. 86 is a circuit diagram showing an example of the bottom detection circuit CT2-2 for the pulsation generating coil WP2-15, and FIG. 87 illustrates the state of the current waveform when the pulsation generating coil WP2-15 is energized. FIG.

As shown in FIG. 86, the bottom detection circuit CT
2-2 is a comparator CT2-3 and a capacitor CT2
-4 and a resistor CT2-5, and the resistor and the capacitor constitute a delay circuit composed of a CR filter circuit. The CR filter circuit delays the input signal by a delay determined by a resistor and a capacitor and outputs the delayed signal. Therefore, the bottom detection circuit calculates an input signal (a voltage generated in the detection resistor CT2-6 reflecting the supplied current) input to the negative terminal and a delay signal obtained by delaying the input signal by a comparator. Process. As a result, a pulse signal (bottom detection signal) indicating the completion of the movement of the plunger is output from the bottom detection circuit to the electronic control unit CT2-1 as follows.

After the completion of the post-nozzle cleaning, the pulsation generating coil W
A pulse signal having a predetermined cycle (constant duty ratio Dtm) shown in the figure is output to the switching transistor CT2-7 of P2-15, and energization of the coil is started in accordance with each pulse. Focusing on a certain pulse, the current flowing through the pulsation generating coil increases with time. And
When a predetermined time has elapsed from the start of energization by the pulse, the plunger starts to move, and a back electromotive force is generated in the pulsation generating coil with the movement of the plunger, so that the energization current once decreases as shown by a solid line in FIG. A bottom phenomenon occurs. This current waveform (original signal waveform) is input as a voltage to the negative terminal of the comparator. On the other hand, a delay signal as indicated by a dotted line in the figure is generated by a CR filter circuit and input to the positive terminal. For this reason, since these signals are calculated by the comparator in consideration of the polarity of the input terminal, a pulse signal is generated as shown in the figure. This pulse-like signal (bottom detection signal) is generated corresponding to each pulse output to the transistor, and is input to the electronic control unit at the predetermined cycle. However, as described above, when the residual washing water is completely drained, the moving speed of the plunger is high, so that the bottom detection signal at this time is input at a different cycle from before. Therefore, from the state of the signal input, the electronic control unit determines completion of the discharge of the residual water, stops the pulse output thereafter, and ends a series of butt cleaning operations. In addition to the completion of the residual water discharge based on such a bottom detection result, it is also possible to stop the pulse excitation and stop the coil excitation when a predetermined time has elapsed from the coil excitation for the residual water discharge, thereby terminating the cleaning operation. it can.

H2 / Move cleaning: In the local cleaning device of the reference example, move cleaning can be performed as follows. For example, the pulsation frequency ftm or the duty ratio Dtm is changed and controlled according to the nozzle position while the cleaning nozzle is reciprocated back and forth about the center position. At this time, the pulsation frequency ftm is increased around the center position to increase
Improves continuity, and the pulsation frequency f near the forward end and the backward end
tm can be lowered to emphasize a hard feeling. Further, if the duty ratio Dtm is also reduced around the center position, a soft feeling can be emphasized. Conversely, in the vicinity of the center position, the pulsation frequency ftm can be lowered to increase the sense of hardness and stimulation, and in the vicinity of the forward end and the backward end, the pulsation frequency ftm can be increased to emphasize softness.

J2 / Massage cleaning: In the local cleaning device of the reference example, massage cleaning can be performed as follows. The massage cleaning period is the repetition of the cleaning periods TA, TB, TC,.
== DtmL), and as shown in FIG. 84 (a), the pulsation frequency ftm is regularly controlled to increase or decrease in this massage cycle. For example, the pulsation frequency ftm is changed to ftmS → ftmm →
ftmL → ftmM → ftmS (ftmS <ft
It changes regularly for every massage cycle like mM <ftmL). Also, ftmS → ftmM → ftmL →
ftmS → ftmm...
Alternatively, in addition to the regular increase / decrease control of the pulsation frequency ftm, as shown in FIG. Dtm is variably controlled regularly. For example, the duty ratio Dtm is changed from DtmL to Dtmm to Dtm.
mS → Dtmm → DtmL ... (DtmS <Dtmm
<DtmL) It changes regularly for every washing period. Also, DtmS → Dtmm → DtmL → DtmS →
Dtmm ... can also be used.

In this massage cycle, the frequency determined by its reciprocal is outside the dead band frequency range described above (less than about 5 Hz).
It is to be. As a result, the user can clearly perceive the transition of the washing feeling and the stimulating feeling accompanying the duty ratio Dtm and the pulsation frequency ftm as described above. Therefore,
The washing feeling and the stimulating feeling received from the water spout can be regularly and repeatedly given to the user, and the regular repeating can also take various forms. Further, when the stimulus is increased by increasing the duty ratio Dtm, if the pulsation frequency ftm is reduced, the sense of continuity of the stimulus is reduced, so that a strong stimulus can be emphasized. Therefore, it is possible to amplify the intensity of the stimulus, and to promote defecation.

[0320] In the massage washing described above,
The cleaning periods TA, TB, TC,... Are different from each other. By doing so, the duty ratio Dtm in each cleaning period or the stimulus recognition time associated with the pulsation frequency ftm is changed, so that the way of receiving a stimulus diversifies,
The feeling of defecation can be more effectively promoted. In addition, by synchronizing with the five senses such as music, light, and odor (aromatherapy), a relaxing space can be provided, and further a feeling of defecation can be further promoted.

K2 / fluctuation cleaning: In the local cleaning device of the reference example, the fluctuation cleaning which gives a feeling of comfort and comfort by irregularly changing the feeling of washing and irritation received from the spouting water is performed as follows. Can be. The fluctuation cleaning period is the repetition of the cleaning periods TA, TB, TC,... At the same time interval, and this time interval is a fluctuation period, and the duty ratio Dtm and the pulsation frequency ftm or both are irregularly increased and decreased in the fluctuation period. Control. For example, as described in the above embodiment, when the duty ratio Dtm or the pulsation frequency ftm is irregularly changed, a random number generation program is loaded to generate a random number, and the obtained random number is used to generate the duty ratio Dtm or the pulsation frequency ftm. Is determined. By doing so, the duty ratio Dtm becomes DtmS → Dtmm
→ DtmS → DtmS → DtmL → DtmS... The pulsation frequency ftm is ftmm → ftmS → ft
It changes with a constant fluctuation cycle such as mM → DtmL → DtmS → DtmL. Alternatively, the two change independently.

In this way, with the transition of the duty ratio Dtm or the pulsation frequency ftm, the washing feeling and the stimulating feeling received from the water discharge change irregularly. In this case, with respect to the above-mentioned fluctuation cycle in which the washing feeling and the stimulating feeling change according to the duty ratio Dtm or the pulsation frequency ftm, the frequency f determined by the reciprocal of the fluctuation cycle is the massage cycle TM.
And the same frequency (less than about 5 Hz). As a result, the duty ratio D
The transition of the feeling of washing and irritation accompanying the tm and the pulsation frequency ftm is clearly sensed by the user. The changing feeling of washing and irritation is different for each fluctuation cycle, and the changing of the feeling of washing and irritation is also irregular. Will receive it. As a result, as in the above-described embodiment, it is easy to cause relaxation of the internal anal sphincter under involuntary elimination of monotonous feeling at the time of washing and parasympathetic nervous state from unpredictability of stimulus change transition, unconsciously, Defecation can be promoted more effectively. Further, if the fluctuation cleaning is performed for local cleaning after defecation, it is difficult to predict a strong stimulus due to a change in the duty ratio Dtm or the pulsation frequency ftm, so that the monotonous feeling at the time of local cleaning can be further eliminated. .

In the fluctuation cleaning described above, each cleaning period TA, TB, TC,... Is different from each other. In this case, since the stimulus recognition time associated with the duty ratio Dtm or the pulsation frequency ftm in each cleaning period is changed, it becomes more difficult to predict the stimulus sensation.
Therefore, defecation can be promoted more effectively. Also,
By synchronizing with the five senses such as music, light, and odor (aromatherapy), a relaxing space can be provided, and the defecation can be further promoted.

Further, the power spectrum of the physical quantity such as the fluctuation cycle or the instantaneous flow rate which determines the transition width of the duty ratio Dtm and the pulsation frequency ftm, and the transition timing thereof, is determined by the biological rhythm of the human body such as the heart rate and the natural world. Similarly to the rhythm of the above, it can be made proportional to the reciprocal of the frequency. This makes it possible to give the user a feeling of relaxation, so that the parasympathetic nerve becomes dominant, the internal anal sphincter is relaxed, and the effect of promoting defecation is enhanced.

According to the above-described local cleaning device of the reference example,
In addition to the above, there are the following advantages. First, the accumulator W provided upstream of the wave generator WP2-8
P2-7 has the following advantages. FIG. 88 is an explanatory diagram for describing an effect obtained by accumulator WP2-7.

By driving the wave generator WP2-8, the above-described pulsating flow of washing water is discharged into the upstream water supply line WP2-8.
5 (see FIG. 60) (primary pressure) and the pressure (secondary pressure) of the downstream water supply pipeline WP2-6 on the downstream side of the wave generator. And the accumulator W
The primary pressure in a state where P2-7 was not provided upstream of the wave generation device WP2-8 was measured downstream of the flow control switching valve WP2-2. Further, the primary pressure when the accumulator WP2-7 was provided as shown in FIG. 60 was measured downstream of the flow control switching valve, that is, upstream of the accumulator. FIG. 88 shows the result.

When the accumulator is incorporated in the upstream of the wave generator of the present embodiment, water hammer reduction, which is an original function of the accumulator, can be exhibited in the upstream water supply line WP2-5, and the following advantages are obtained. is there. That is,
As shown in FIG. 88, when a pulsating flow is generated by the wave generation device, the pressure fluctuation of the primary pressure in the upstream water supply pipe can be effectively suppressed. Therefore, it is possible to avoid the disturbance of the temperature distribution of the washing water in the tanks TH1 to TH3 by suppressing the water hammer as described above.
It is possible to avoid disturbance of the washing water temperature distribution of the tank by suppressing the next pressure fluctuation. Therefore, since the heater can be used to warm the tank with no disturbance in the temperature distribution, the heater control can be simplified and the temperature of the washing water can be made uniform with good responsiveness. Moreover, the pulsating flow generated by the wave generating device is in a state where the primary pressure is accumulated by the accumulator and amplified on the secondary side,
It is possible to reduce the capacity and size of the wave generation device.
In addition, the pressure gain by the accumulator can be obtained,
In the wave generation device, the energy required for pressure fluctuation generation (pulsation generation) is reduced, and power saving can be achieved. Although the accumulator is arranged close to or integrated with the wave generation device WP2-8, the accumulator may be arranged close to the flow control switching valve WP2-2 or integrated with the device. it can.

In the local cleaning device of this reference example, when the cleaning water is discharged by periodically varying the flow of the cleaning water, the wave generating device W utilizing the reciprocating motion of the plunger.
P2-8 was used to prevent the pulsating flow generated by this wave generating device from appearing at a zero flow rate. Therefore, a situation in which the flow of the washing water in the pipeline is not interrupted does not occur, so that no water hammer is generated. For this reason, it is not necessary to make the water path components such as the wave generating device high in water hammer resistance, and the configuration and structure can be simplified, the size can be reduced, and the resin can be used.

Further, in the wave generation device WP2-8, when the pulsation is generated by the reciprocation of the plunger, the condition of zero flow rate is not developed as described above. Do not need. For this reason, the structure and structure can be further simplified and downsized. And since such miniaturization can be achieved, the degree of freedom of the installation location of the wave generation device is increased, and attachment and integration with other members having a large mass are simplified.

Further, since the flushing water with a zero flow rate does not occur when the pulsating flushing water is discharged, the following advantages are provided. The pulsation frequency is within the dead band frequency range (about 5 Hz or more)
Even so, it can be said that the continuity of the stimulus of the user receiving the water discharge tends to fade as the pulsation frequency approaches the lower limit of the dead band frequency region. However, as described above, since the flush water discharge state with the zero flow rate does not occur, the sense of continuity of the stimulus can be hardly faded. Therefore, the wave generation device WP2
In the flush water spouting of the pulsating flow by -8, the adjustment range of the pulsating frequency can be extended to near the lower limit of the dead zone region,
By adjusting the pulsation frequency in a wide range, it is possible to diversify the washing feeling and the water force.

Further, in the local cleaning device of this reference example, at the end of the cleaning operation in the buttocks cleaning, the soft cleaning and the bidet cleaning, the plunger is reciprocated by driving the wave generation device WP2-8 as described above. The remaining washing water was forcibly discharged. Therefore, the drainage of the pipe from the flow control switching valve WP2-2 to the nozzle head of the washing nozzle WN2-1 is completely performed. Therefore, freezing of the remaining water can be reliably avoided. After the residual water is completely discharged by the wave generation device, the flow control switching valve WP2-2 is switched to the functional water unit side to drain the water from the flow control switching valve WP2-2 to the functional water unit. This is preferable because freezing in this pipeline can be prevented. When driving the wave generation device for draining such water, the duty ratio Dtm of the pulsation generation coil WP2-15 is reduced and the pulsation frequency ftm is set to a low frequency, so that the plunger is moved at a constant speed and with a weak force. The plunger does not collide with the cylinder end with high speed and strong force. For this reason, the sound of the plunger can be reduced. Furthermore, as described above, when the flow path switching valve is opened at the time of draining, all communication holes of each nozzle flow path can be drained at all the flow paths in the cleaning nozzle.

In addition, in the local cleaning device of this reference example,
As described above, the user is provided with a feeling that he or she is receiving continuous water discharge, while reducing the amount of wash water (water discharge amount) to increase the effectiveness of water saving. Therefore, it is possible to reduce the power consumption for heating the cleaning water to the desired temperature by the heaters TH1-2. That is, the limit capacity of the outlet in the toilet room is generally 15A. However, in a local cleaning apparatus conventionally used in a toilet, the capacity of a hot water heater of an instantaneous heat exchanger is set to about 2500 watts in order to enable a sufficient temperature and a sufficient time of water discharge even in a cold season. I have. In order to reduce the heater capacity, air is forcibly mixed into the cleaning water to reduce the amount of cleaning water. However, even in this case, a heater capacity of at least 1000 watts or more is required. Was. For this reason, when a local cleaning device having such a heater capacity is plugged into an outlet in a toilet room, the limit capacity of the outlet is approached, so that there is a problem that other electric devices cannot be connected.
In addition, when the hot air drying function and the indoor heating function provided in the local cleaning device are simultaneously operated, the overall heater capacity increases. Therefore, when these functions are simultaneously operated, there is also a problem that a measure such as stopping the energization of any heater has to be taken.
In addition, although it is necessary to install a plurality of local cleaning devices in hotels and facilities, there is a problem that they cannot be installed due to an upper limit of power consumption. However, according to the local cleaning device KS2-1 of this reference example, the wave generation device WP
A pulsation is generated according to 2-8, and a pulsation frequency f of the pulsation is generated.
Through the control of tm and the duty ratio Dtm, the amount of washing water and the power consumption can be significantly reduced, and the above-described power supply problem can be solved.

In the local cleaning device of the above-described reference example, the flow rate of the cleaning water reaching the wave generator WP2-8 is detected by a flow sensor (not shown). Therefore, as described above, fine water pressure adjustment by pulsating flow control (duty ratio control, pulsating frequency control) using the flow rate detected by this sensor is possible, and the following advantages are provided. That is, the electronic control unit CT2
−1, when an excessive flow rate occurs due to a failure of the solenoid valve or when an abnormality such as water cutoff occurs, the detection signal from the flow rate sensor is received, the drive of the wave generation device WP2-8 is stopped, and the heater TH1-2. The power supply to the cleaning nozzle WN2-1 is returned to the standby position, and the like. In this way, it is possible to avoid occurrence of a tapping sound due to the idling of the plunger, and to avoid idling of the heater.

Next, the local cleaning device KS of the above-described reference example
A modified example of 2-1 will be described. It is to be noted that the same members and the same reference numerals are used as they are for the same members as those of the above-described embodiment or the modified example, and the same member names are used for members performing the same function.

B2-1 / Modification of Channel System Configuration; FIG.
FIG. 90 is a block diagram illustrating a water channel configuration of a local cleaning device according to a modification, FIG. 90 is a block diagram illustrating a water channel configuration of a local cleaning device according to another modification, and FIG. 91 is a flow control switching valve according to these variations. It is a schematic block diagram which shows the schematic structure of WP2-20 with a part broken away. FIG. 92 is a block diagram illustrating a water channel configuration of a local cleaning device according to another modification. FIG. 93 is a cross-sectional view illustrating a configuration of an on-off valve WP2-27 arranged in the waterway system, and FIG. 94 is an explanatory diagram illustrating water pressure in a waterway system of a local cleaning device of a modified example having the on-off valve. . FIG. 95 is a block diagram illustrating a water channel configuration of a local cleaning device according to another modification. It is.

(1) As shown in FIG. 89, in this modification, the accumulator WP2-7 and the wave generator WP2
-8 is provided downstream of the heat exchange unit TH1-1, and a flow control switching valve WP2-20 is provided downstream of this wave generation unit. This flow control switching valve is configured separately from the washing nozzle WP2-1,
The water supply destination of the washing water is switched to one of the above-described nozzle flow paths of the cleaning nozzle (each nozzle flow path for ass cleaning, soft cleaning, and bidet cleaning) and a flow path leading to the functional water unit WP1-4. At the same time, the flow rate of the washing water flowing through each of the switched flow paths is adjusted. Therefore, with this flow control switching valve, water supply switching between the washing nozzle and the functional water unit, water supply switching for each nozzle flow channel in the cleaning nozzle, and cleaning water flow rate adjustment to each flow channel can be performed. Therefore, in the above reference example,
Two valves were used: a flow control switching valve WP2-1 for switching water supply to the washing nozzle and the functional water unit and adjusting the flow rate, and a flow path switching valve WN2-2 for switching each nozzle flow path of the washing nozzle. However, in this modification, one flow control switching valve WP2-
20 is enough. Therefore, there are advantages in manufacturing such as a reduction in the number of assembly steps and a reduction in cost due to the reduction in the number of parts.

(2) In another modification shown in FIG. 90, separate washing nozzles for the buttocks and bidet are provided, and each nozzle is connected to the flow control switching valve WP2-20 of the above modification. .
And, this flow control switching valve is used for the ass washing nozzle WN2-
22 and the bidet cleaning nozzles WN2-23, and the water supply destination of the cleaning water is switched and switched to the nozzle flow paths (bottom cleaning nozzle flow path and bidet cleaning nozzle flow path) for each of these cleaning nozzles. Adjust the flow rate of washing water flowing through each flow path. In addition, it is also possible to provide a functional water unit as described above and switch the water supply to the unit.

Wash nozzle WN2-2 for buttocks and bidets
2 and 23 are mounted on the nozzle device NS2-10. This nozzle device is configured to separately advance and retreat the respective cleaning nozzles from the standby position to the respective cleaning positions,
The drive is controlled by an electronic control unit. As described above, even in the local cleaning device having separate cleaning nozzles for the buttocks and the bidet, as described above, the control of the pulsation frequency ftm and the duty ratio Dtm increases the efficiency of water saving. Various washing feelings and water levels can be set.

The flow control switching valve WP2-20 of these modified examples
May be, for example, a drum type flow control switching valve as shown in FIG. In this flow control switching valve, a drum WP2-22 is rotatably (forward / reverse) inside a drum casing WP2-21. On the drum surface, water supply grooves WP2-23 are formed for each water supply port, and the degree of overlap between each water supply groove of the drum and the water supply port is adjusted to switch the water supply destination and to the switched water supply destination. Adjust the feedwater flow rate. According to this drum type flow control switching valve, pulsation damping can be more effectively suppressed as compared with a switching valve utilizing the elasticity of an elastic body such as a diaphragm.

[0340] Further, in the apparatus provided with the buttocks washing nozzle WN2-22 and the bidet washing nozzle WN2-23, one of the buttocks and bidet washing nozzles is provided with a soft washing water discharge hole and a It may have a nozzle flow path. Further, a cleaning nozzle for soft cleaning may be provided separately from the above-mentioned two cleaning nozzles.

(3) In the modification shown in FIG. 92, the flow of the cleaning water is instantaneously reduced by pressurizing the supplied cleaning water and interrupting the flow of the cleaning water downstream thereof. The feature is that the flow is intermittent. That is, the local cleaning device of this modified example has a heat exchange unit TH1-1 in the waterway system.
WP2-25 and the flow control switching valve WP2
-2 and an intermittent flow generation unit WP2-26, and discharges cleaning water from a cleaning nozzle WN2-1 via a flow path switching valve WN2-2.

The pressurizing device WP2-25 is a line pump or the like.
Heat exchange unit TH1-1
Pressurized cleaning water supplied from
I do. This pressurizing device is regulated by the pressure regulating valves WP2-4.
1.3 kgf / cm pressed ^TwoOf about 2kgf /
cm^Two It has a pump capacity to increase up to. In addition, this
Pressure regulating pressure (1.3kgf / cm)^Two)
It is almost the same as the conventional product.

The intermittent flow generating unit WP2-26 has an accumulator WP2-7 from the upstream side and an intermittent valve WP2-27 for interrupting the flow path. Intermittent valve WP2-27
As shown in FIG. 93, the motor WP2-28 rotates the valve body WP2-29 inside the housing WP2-30. The on-off valve connects and disconnects the internal valve body flow path WP2-31 with the valve flow path WP2-32 in synchronization with the rotation cycle of the motor. Thus, the intermittent valve supplies the cleaning water flow pressurized by the pressurizing device WP2-25 as an intermittent output (intermittent flow), and supplies the intermittent cleaning water to the cleaning nozzle. The state of generation of this intermittent flow will be described with reference to the drawings as follows.

As shown in FIG. 94, when the water supply pressure from the water supply source is Pw, the pressure of the washing water is reduced to 1.3 kgf / cm ² by the pressure regulating valve WP2-4, and the pressure of the pressurized equipment W is increased.
It reached P2-25, and about 2 kgf / cm ²
Up to And this washing water is supplied to the intermittent valve WP2.
In response to the periodic interruption of the washing water flow by -27, the washing water is made into an intermittent flow and discharged from the washing nozzle. Since the intermittent cycle DT of the intermittent flow at this time is twice the motor rotation cycle of the intermittent valve, the intermittent flow can be variably controlled through motor rotation control by the electronic control unit CT2-1. In this modification, the frequency (intermittent frequency) defined by the intermittent cycle DT is in the dead band frequency range (5 Hz or more, preferably 1 Hz or more).
0 to 100 Hz). Therefore, even in this modified example in which the intermittent flow of washing water obtained through intermittent flow of the flow path is spouted from the washing nozzle, the amount of washing water is constant by controlling the frequency of washing water spouting as in the reference example. However, it is possible to diversify the washing feeling and adjust the water level. In addition, since the flow rate of the washing water can be changed when the adjustment of the amount of the washing water is used in combination, it is possible to further diversify the feeling of washing and finely adjust the water level. Further, since the water pressure can be adjusted by the frequency control as described above, the water pressure desired by the user can be ensured even if the amount of the washing water is insufficient. In other words, since the user's desired feeling of washing and water force can be secured by controlling the frequency of the intermittent flow, the amount of washing water can be significantly reduced as described above.

According to this modification, there are the following advantages. As shown in FIG. 93, the intermittent valve WP2-27 has an inclined portion WP2-33 at the opening of the valve body flow path WP2-31. This inclined portion functions to gradually close the valve flow path when the valve body WP2-29 rotates the valve flow path WP2-32 to the shielding side. Therefore, at the time of driving the intermittent valve for generating the intermittent flow, it is possible to suppress the occurrence of water hammer when the flow path is cut off due to the driving of the valve.

(4) In another modified example shown in FIG. 95, the pressurizing device WP2-25 and the intermittent flow generation unit WP2-26 pressurize the wash water to produce intermittent flow wash water. Also,
The washing nozzles WN2-22 and 23 for buttocks and bidets are advanced and retracted by the nozzle device NS2-10, and the flow control switching valve WP2 is used.
At -20, the flow path to the nozzle is switched and the flow rate is adjusted. Then, after the flow rate is adjusted, the above-mentioned intermittent flow of washing water is spouted from each of the buttocks and bidet washing nozzles. As described above, the apparatus having the separate washing nozzles WN2-22 and 23 for the buttocks and the bidet may be configured to discharge intermittently flowing washing water.

E2-1: Deformation of Cleaning Nozzle: In order to improve the soft feeling in each local cleaning, a modification can be made so that air is forcibly mixed into the cleaning water. FIG. 96
Is a modified cleaning nozzle WN2-
FIG. 97 is an explanatory diagram for explaining the configuration of No. 25, and FIG. 97 is a graph showing the relationship between the amount of air entrapment when air is forcibly mixed into the cleaning water and the cleaning area of the cleaning water spouted with air. . FIG. 98 is an explanatory diagram illustrating the configuration of a cleaning nozzle WN2-25 according to another modification for forcibly mixing air.

(1) As shown in FIG. 96, the cleaning nozzle WN2-25 of the modified example is attached to the nozzle head NH2-10.
Water discharge holes NH2- for ass washing, soft washing, bidet washing
The first to fourth head channels NH2-5 to NH4 communicating with the first to fourth head channels NH2-5
It has the third air passages NH2-11 to NH13. These air flow paths are formed by the cylindrical portion WN2- of the cleaning nozzle WN2-25.
5 in the upper compartment WN2-26.
2-27 to 29 are individually connected. The compressed air sent from the air pump WN2-30 is supplied to each of the air pipes at a flow rate adjusted by an air flow rate adjustment valve WN2-31. The air flow control valve also switches air supply to each of the air pipes WN2-27 to 29.
Therefore, the compressed air is blown into each head channel through each air channel in the nozzle head. The cleaning water flowing in each of the head flow paths in a pulsating flow or an intermittent flow is subjected to frictional force generated by blowing compressed air while being discharged in a water mass as described above due to water discharge in the pulsating flow or the intermittent flow. For this reason, by blowing compressed air, the cleaning water is discharged as a minute water mass as shown in the figure. Even if these minute water bodies are ejected from the water discharge holes, they are in a state in which they are hardly combined with each other again.

When air is mixed in this way, as shown in FIG. 97, it can be seen that the water mass is finely dispersed and the cleaning area increases as the flow rate of the blown air increases. Therefore, when the amount of water is reduced and the cleaning range is narrowed, the cleaning range can be expanded by increasing the air flow rate. As shown in FIG. 75, the pulsating flow or intermittent flow of cleaning water discharged from the water discharge hole is increased into a large water mass. Can be made small, so that a soft washing feeling can be obtained. In this way, by blowing air, it is possible to increase or decrease the cleaning range and adjust the cleaning intensity. In addition, the washing strength and the like can be more finely adjusted in combination with the adjustment of the water force and the washing feeling in the pulsating flow or the intermittent flow. Furthermore, the amount of washing water can be reduced by the amount of air mixing, and a soft feeling of washing can be provided while enhancing the effectiveness of water saving.

(2) As shown in FIG. 98, the cleaning nozzle of another modified example has head head channels NH2-
First to third air pipes NH2-16 to 18 are respectively inserted into the water discharge holes NH2-2 to NH4 of Nos. 5 to 7, respectively. The first to third air pipes are connected to the air pump WN2-
30. Therefore, the compressed air from the first to third air pipes is jetted directly into the cleaning water flowing through each head channel. According to this configuration, since air is directly blown into the cleaning water flow, the action of dispersing the cleaning water flow can be further enhanced.

E2-2 / Other Modifications of Washing Nozzle: The washing nozzle may be modified to take advantage of the negative pressure of the washing water flow to achieve natural aspiration. FIG. 99 and FIG. 100 are schematic cross-sectional views of main parts of the cleaning nozzles of the respective modified examples for natural suction. FIG. 101 is a schematic diagram schematically illustrating a cleaning nozzle according to another modification for achieving natural suction, and FIG. 102 is a graph illustrating air entrainment characteristics according to another modification.

(1) As shown in FIG. 99, the nozzle head NH2-20 of the cleaning nozzle of this modification has head passages NH2-20 for butt cleaning, soft cleaning, and bidet cleaning.
An orifice NH2 for reducing the flow path area is provided in a part of 5-7.
-21 to 23. Further, downstream of each of the orifices, an outside air introduction passage NH2-24 to introduce outside air from the back of the nozzle head is provided. According to this configuration, a negative pressure is generated when the flow of the cleaning water flowing out of each orifice increases the flow path area, and air is mixed into the cleaning water from each external air introduction passage. According to this modification, there is no need to provide an air pump or the like, so that the configuration can be simplified.
In this case, each orifice corresponding to the head flow path of the tail cleaning, the soft cleaning, and the bidet cleaning may have a different orifice diameter for each of the tail cleaning, the soft cleaning, and the bidet cleaning. For example, the orifice diameter is defined so that the amount of air entrainment in soft cleaning / bide cleaning is larger than that in bottom cleaning. If you do this, you can wash your ass,
Since the degree of mixing of air is different in each bidet cleaning, the cleaning feeling can be changed for each cleaning operation.

(2) In another modification shown in FIG. 100, the nozzle head NH2-27 includes a nozzle flow path N for bidet cleaning.
An external air introduction pipe NH2-28 is arranged and provided in H2-7. Even in this case, air can be directly introduced into the washing water stream. The same applies to the nozzle flow path for ass cleaning and soft cleaning.

(3) In another modification shown in FIG. 101, the following configuration is provided to improve the efficiency of natural aspiration. In addition, for convenience of explanation, one water discharge hole (butt water discharge hole) will be described, but the same applies to a soft water discharge hole and a bidet water discharge hole. Another modification is a nozzle head NH2-
30 is provided with an outside air entrapment chamber NH2-31. The nozzle head is provided with an orifice N in the head channel NH2-5 for cleaning the buttocks with the outside air entrapment chamber interposed therebetween.
The H2-21 and the tail water discharge hole NH2-2 are arranged to face each other, and the outside air entrainment chamber is provided with an outside air introduction passage NH2-24. With this configuration, a so-called jet pump having the washing water discharged from the orifice as the driving fluid, the air from the outside air introduction passage as the driven fluid, and the buttocks discharge hole as a throat is formed.

In this modification, the orifice NH2-21
Are provided in the same direction as the wash water spouting direction,
The damping of the water force can be suppressed. Further, the amount of air entrainment can be increased by the action as the jet pump. Therefore, the amount of washing water can be reduced by an amount corresponding to the increase in the amount of air, and the effectiveness of water saving can be further improved.
A softer feeling of washing can be provided.
Furthermore, since the orifice and the flush water spouting direction are the same, there is no bending of the pipe downstream of the orifice. Therefore,
Since the collision of the washing water does not occur at the bent portion of the pipe, there is no energy loss and the flow velocity does not decrease.

In this modified example, the amount of air entrainment was measured by variously changing the area ratio (S2 / S1) between the orifice diameter S1 and the throat diameter S2. The amount of air entrainment was expressed as a ratio of air to water (air mixing ratio%) and graphed. As shown in FIG.
If so, a large air entrapment amount of 40 to 80% could be obtained. That is, when the jet pump is configured as in this modified example and the area ratio is set to 1 to 4, it is about 1.2 to 2 times as large as that having the orifice and the outside air introduction passage as shown in FIG. In addition, the amount of air entrainment can be increased, which is advantageous for improving the effectiveness of water saving and for giving a soft feeling of washing. In addition, the air entrapment amount was measured as follows. That is, a micro wire air flow meter of the hot wire type is connected to the air inlet, and the air flow rate is directly measured. 102 graphs were obtained.

E2-3 / Another Modification of Washing Nozzle; FIG. 103 is a schematic view showing a nozzle head NH2-33 in which the washing nozzle shown in FIG. FIG. 104 is a perspective view, and FIG. 104 is a graph showing air entrainment characteristics in a nozzle head NH2-33 according to another modification.

As shown in FIG. 103, the nozzle head NH2-33 of this modification is similar to the nozzle head NH2-33 described above.
Similarly to 30, the outside air entrapment chamber NH2-31, the orifice NH2-21, and the tail water outlet NH2-2 as a throat
And a jet pump configured with an outside air introduction passage NH2-24. The nozzle head has a cleaning water vortex chamber NH2-34 between the orifice and the head passage NH2-5 for cleaning the buttocks. The washing water vortex chamber has an inner peripheral wall which has a larger diameter toward the bottom and is inclined from the bottom to the orifice. Since the head flow path is eccentrically connected to the washing water swirling chamber as shown in the figure, the washing water flowing into the swirling chamber is moved along the inclined inner peripheral wall as shown by an arrow SY in the figure. Turn. Then, the washing water swirled in this way is discharged with a large amount of air entrained when water is discharged from a throat (butt water discharge hole) through an outside air entrapment chamber by adding an orifice.

The washing water discharged in this manner is affected by the swirling force of the washing water itself, and adopts a spiral water discharging form as schematically shown in the figure. In this modification, when the washing water flows into the washing water vortex chamber NH2-34, the washing water is supplied from the head channel NH2-5 for ass washing in the above-described pulsating flow or intermittent flow. Therefore,
The flush water discharged in this manner adopts a spiral water discharge form with air mixed therein as shown in the drawing, while maintaining the above-described water discharge property in the pulsating flow or intermittent flow. The swirling force of the washing water is determined by the inflow speed (washing water speed) of the washing water into the washing water swirl chamber, and the inflow speed defines the degree of swirling of the washing water in the washing water swirling chamber. Also, the degree of aeration is determined by the washing water speed. Therefore, by adjusting the washing water inflow speed (washing water speed) into the washing water swirl chamber, it is possible to variously adjust the degree of spiral expansion and the degree of air mixing in the spiral water discharge form. Since the extent of the spiral affects the cleaning area, in this modification, the cleaning area can also be adjusted. The washing water speed can be variously changed by frequency adjustment or duty ratio adjustment in a pulsating flow or an intermittent flow, and flow adjustment by a flow regulating valve. Therefore, it is possible to discharge water with various cleaning areas and discharge water with various air mixing amounts, and it is possible to provide a more comfortable cleaning feeling, a soft feeling, and the like. In addition, it is possible to realize water pressure adjustment at a low flow rate by a pulsating flow or an intermittent flow.

Also in this modified example, when the area ratio (S2 / S1) of the orifice diameter S1 and the throat diameter S2 was variously changed and the air entrapment amount was measured, the result shown in FIG. 104 was obtained. That is, about 1.3 to 2 times as compared with the above-described nozzle head NH2-30 having no vortex chamber (see FIG. 101).
The air entrapment amount can be increased about twice as much, which is further advantageous from the viewpoint of improving the effectiveness of water saving and providing a soft feeling of washing. It is preferable to set the area ratio to about 1.2 to 3 from the viewpoint of increasing the amount of air entrainment. The air entrainment was measured by the same method as described above.

In the nozzle head NH2-33 of the modification shown in FIG. 103, the degree of spiral expansion and the degree of air entrainment in the spiral water discharge form are determined by the flow rate of cleaning water into the cleaning water swirl chamber (the cleaning water velocity). Stipulated. Therefore, only by supplying the continuous flow of cleaning water that has been subjected to normal flow rate adjustment using a flow rate adjusting valve or the like, it is possible to discharge water in various cleaning areas and water with various amounts of air mixed in. Soft feeling and the like can be imparted. In other words, according to the above-described nozzle head NH2-33, it is not necessary to supply the cleaning water in a pulsating flow or an intermittent flow state. The existing device can be easily improved so as to give a soft feeling or the like.

In addition, this nozzle head NH2-33
Only the extent of the spiral in the spiral water discharge form is defined by the washing water inflow speed (washing water speed) into the washing water swirl chamber.
Therefore, it is possible to discharge water in various cleaning areas depending on the extent of the spiral by merely supplying the continuous flow of the cleaning water whose normal flow rate is adjusted by a flow rate adjusting valve or the like. For this reason, in the above-described nozzle head NH2-33, a comfortable cleaning feeling, a soft feeling, and the like can be imparted even if the configuration relating to the supply of the cleaning water and the entrainment of air in a pulsating flow or an intermittent flow is omitted.

The nozzle head NH2-33 has
It is also possible to forcibly mix air using an air pump or the like. In this way, the amount of air mixed in increases, so that a more soft feeling can be provided. In a case where forced air mixing is performed in this way, the above-described pulsating flow or intermittent flow of washing water is discharged while forced air mixing is performed, or the forced air mixing is stopped. It is also possible to discharge water with a pulsating flow or intermittent flow of cleaning water.

[0364] In the above-described reference example and each of the modifications, the head flow paths for the tail cleaning, the soft cleaning, and the bidet cleaning in the nozzle head may be formed vertically. By doing so, the width direction of the cleaning nozzle can be narrowed, various devices and units including the nozzle device can be arranged close to each other, and the size of the device can be reduced. In this case, the nozzle flow path can also be formed vertically in the cleaning nozzle in conjunction with the upper and lower head flow paths. Further, the nozzle head may be configured such that a head cover having the above-described water discharge holes is mounted on a base having the above-described respective head flow paths, and an outside air introduction hole is provided between the base and the head cover.

In addition, the local cleaning device of the above-described reference example or each modified example can be modified as follows. (1) Although the above-described wave generation device WP2-8 was used for making the pulsating flow of washing water, a pump capable of obtaining a pulsating output, such as a gear pump or a trochoid pump, can be used. In this case, the pulsation frequency can be variably controlled through the rotation speed control of these pumps to adjust the water force and the like. In addition, the wave generation device WP2-
8, the phase angle control may be performed by using the AC drive as the AC drive, and similarly to the duty ratio control in the above-described reference example, the water force or the like may be adjusted. (2) In addition, the intermittent valve WP2-27, which makes intermittent flushing water through intermittent flow, is opened and closed with a solenoid valve using a solenoid or a water supply poppet to open and close the water supply port. May be a poppet type valve.

(3) A pressurizing device WP2-25 having a pressurizing pump composed of a line pump and an intermittent valve WP2-27 are used for pressurizing the washing water and thereafter forming the intermittent flow, and these two are separated. Configuration. However, the configuration is not limited to this, and the cleaning water may be pressurized and intermittent. FIG.
5 is an explanatory view illustrating a cleaning nozzle WN2-35 of still another modification, and FIG. 106 is an explanatory view illustrating a schematic configuration of a solenoid pump WN2-36 used in the cleaning nozzle of this modification.

[0367] As shown in the figure, this solenoid pump has a suction-side check valve WN2-37 and a discharge-side check valve WN2-.
This is a normal flow type electromagnetic pump having 36. And
This solenoid pump is an electromagnetic solenoid WN2-39.
And the plunger WN2-40 is moved forward and backward to obtain pressurized water intermittently flowing from the pump chamber WN2-41. Normal solenoid pumps are
An accumulator is also used in order to eliminate fluid intermittent as the plunger moves between the discharge side check valves and to obtain a smooth pressure. However, the solenoid pump WN2-36 of this modified example can obtain an intermittent cycle synchronized with the excitation voltage of the electromagnetic solenoid by using the intermittent pressure without using an accumulator. According to this embodiment, since the pressurizing section and the intermittent section can be realized by one solenoid pump WN2-36, the configuration can be simplified. Even in this case, the excitation cycle of the electromagnetic coil, that is, the intermittent cycle, is set so that its frequency falls within the dead band frequency range described above.

(4) In addition, the pressurizing device WP2-25 and the intermittent valve WP2-27 are used for pressurizing the washing water and thereafter making the intermittent flow.
As shown in FIG. 94, the intermittent flow in which the pressure periodically fluctuates with the pressure regulating pressure of the pressure regulating valve as the maximum pressure as shown in FIG.
An intermittent flow in which the pressure fluctuates periodically may be set to the minimum pressure of the pressure regulating valve. In this way, even if the pressure of the water supply source itself such as water supply is originally low,
Water can be spouted with intermittent flushing water as described above.

(5) Further, in the above-described reference example and its modified example, by stopping the driving of the wave generation device WP2-8 and the like, it is possible to discharge the washing water by the continuous flow as in the related art. Therefore, a button for selecting the on / off state of the pulsating flow of water is provided on the remote control device, the sleeve of the main body, or the like. It is also possible to select the same type of water discharge as the conventional one by using the local cleaning in the above and the continuous flow of cleaning water.

(6) The tank TH of the heat exchange unit
A buffered hot water storage tank may be provided on the tapping side of 1-3 and may be used in place of the accumulator WP2-7. The configuration of the buffered hot water storage tank includes a tank arranged so as to have a higher water level than the tank.
And the vacuum breakers TH1-4. This buffered hot water tank absorbs pressure fluctuations propagating from the downstream side to the tank in almost the same manner as the accumulator. Therefore, even with this buffered hot water storage tank, disturbance in the temperature distribution in the tank can be suppressed by fluctuation absorption, and the temperature in the tank can be made uniform, thereby stabilizing the temperature control characteristics. A mixing plate or a mixing passage for promoting mixing of hot water may be provided in the buffered hot water storage tank to further enhance the pressure fluctuation absorbing effect. Further, the buffered hot water tank may be integrated with the heat exchange unit, and a mixing plate or the like may be installed inside the heat exchange unit.

(7) In order to detect the temperature of water supplied to the heat exchange unit, instead of using a water temperature sensor, for example, the derivative of the amount of power supplied to the heater is determined based on the amount of power supplied to the heater. It may be calculated based on the value.
This eliminates the need for an incoming water temperature sensor and simplifies the configuration. The same applies to the above embodiment. Moreover,
Incoming water temperature sensor SS16a and outgoing water temperature sensor SS113
Can be provided not only in the tank but also before and after the heat exchange unit as long as it reflects the temperature of the hot water in the tank.

(8) In the pulsating or intermittent flow of flush water described above, the flow rate can be variably controlled while keeping the flow rate constant. First, pulsating flush water discharge (hereinafter referred to as pulsating water discharge) using the wave generation device WP2-8 will be described. FIG. 169 shows a deceleration control of the flow velocity vm (vm2 → v
m3). In the figure, t2 and t3 (> t2) represent the energization time for exciting the coil of the wave generator, T2 is the pulsation generation cycle of the pulsation generated by the wave generator, and V is the pulsation generator. It represents the voltage applied to the switching transformer for turning ON / OFF the pulsation generating coil, in other words, the coil excitation voltage. In the figure, (a) shows the state of the duty ratio of the pulse signal, (b) shows the relationship between the voltage V and time,
(C) shows the relationship between the flow velocity vm-time of the flushing water discharged,
Each is represented. With reference to FIG. 169, a description will be given of a control for increasing the flow velocity while keeping the flow rate constant in the pulsating water discharge.

When the pulsation generator is composed of a pulsation generating coil and a plunger driven by this coil, the flow rate depends on the stroke length of the driven plunger, and the flow rate depends on the driving speed of the plunger, ie, the suction force of the plunger. Are defined respectively. First, assuming that deceleration is to be performed, the voltage V applied to the pulsation generating coil (that is, the current flowing to the pulsation generating coil) is reduced (V3 → V2; see (b)). As a result, the suction force of the plunger decreases and the flow velocity decreases. At this time, if the duty ratio is the same before and after the voltage change, the stroke length of the plunger is shortened by the reduction in the driving speed of the plunger, and the flow rate is reduced. Therefore, if it is sufficient to reduce the flow rate even if the flow rate is reduced,
More than simply reducing the voltage with a constant duty ratio as described above. The reverse is true for increasing the flow velocity.

On the other hand, in order to accelerate / decelerate only the flow rate without changing the flow rate, the following control is performed. In the case of the deceleration control, the duty ratio is increased (t2 / T2 → t) in order to shorten the stroke length, that is, compensate for the insufficient flow rate.
3 / T2; (a)). When the duty ratio is increased in this way, the coil excitation period also becomes longer, so that the plunger can be driven by the regular stroke and the stroke length of the plunger can be kept constant. Therefore, only the flow velocity can be reduced while keeping the flow rate constant. This phenomenon is
In the left and right graphs (c) showing the relationship between the flow velocity and time,
This can also be explained from the fact that the areas S2 during one cycle are equal. In the case of speed-up control, the reverse is true. Of course, in addition to this, when pulsation is constantly generated at the stroke limit of the plunger, the flow rate does not change because the drive stroke length does not change, just by controlling the applied voltage or energizing current to the pulsation generating coil, Control with constant flow rate and variable flow rate becomes possible.

(9) Further, as another example of increasing the flow rate without changing the flow rate, intermittent flow of flush water using a pressurizing pump and an on-off valve can be performed as follows. When the pressure applied to the wash water is increased by the pressurized pump,
The flow rate of the washing water increases (substantially proportional to 1/2 power). At this time, by shortening the opening time of the on-off valve communicating with the water discharge hole (decreasing the opening time duty), it is possible to keep the washing water constant while increasing the flow velocity.
Furthermore, if the reciprocating motion of the plunger is not used as a means for adding the energy of spouting water to the washing water, but as a means for increasing or decreasing the cross-sectional area of the flow passage similar to the opening and closing valve,
As described above, by increasing the pressure applied to the washing water by the pressurizing pump, the flow rate can be increased without changing the flow rate. Further, even if the above-described control of the pressurizing pump is performed in combination with the acceleration / deceleration control of the flow rate in the constant flow rate described above, the flow rate can be controlled independently of the flow rate.

Next, another reference example will be described.
FIG. 107 is a schematic cross-sectional view of a main part of a cleaning nozzle WN3-1 of a local cleaning device of another reference example. FIG. 108 is a schematic cross-sectional view of a main part of a cleaning nozzle WN4-1 of another reference example. Is an exploded perspective view of a main part of the cleaning nozzle WN4-1. In the following description, the same member names and the same reference numerals will be used as described above.

As shown in FIG. 107, the cleaning nozzle WN3-1 of the reference example is provided with a nozzle head NH3-1 at the tip of a nozzle cylinder WN3-2 in a watertight manner. This nozzle head has a bottom water discharge hole NH3-2 and a bidet water discharge hole NH3-3 on its upper surface, and a first head flow path NH3-4 for guiding cleaning water to each of the water discharge holes inside the head. And a second head passage NH3-5. Further, the first inflow chamber NH into which the cleaning water flows is provided at the confluence of each water discharge hole and each head flow path.
3-6 and a second inflow chamber NH3-7 are formed. The first and second inflow chambers have first and second turbines NH3-8 and NH3-9, respectively.
Is incorporated. The first and second turbines are rotatably supported in the respective inflow chambers, and are rotated in the direction of the arrow in the figure by the washing water flowing into the inflow chambers.

The first and second turbines NH3-8 and NH3-9 are provided with a plurality of blades at equal intervals from the center thereof, and the water discharge holes of the first and second inflow chambers NH3-6 and NH3 are provided between adjacent blades. Shielding plate NH3-1 that closes the opening (inflow chamber side opening)
Has zero. In this reference example, three shielding plates are formed at equal intervals. It should be noted that one shield plate may be provided over half of the blades of the water turbine.

The cleaning nozzle WN3-1 has first and second nozzle channels WN3-3, 4 communicating with the first and second head channels NH3-4, 5 in the nozzle cylinder. The washing water heated by the heat exchange unit (not shown) has a flow rate adjusted by a flow control valve (not shown),
It flows into the second head channels NH3-4, NH5. Then, the washing water is discharged from the tail water discharge hole NH3-2 or the bidet water discharge hole NH3-3 via the first and second head flow paths and the first and second inflow chambers NH3-6 and NH3.

As described above, the cleaning water is supplied to the first and second inflow chambers NH.
When passing through 3-6 and 7, the washing water collides with the blades of the turbine and exerts a rotational force on the turbine to rotate the turbine.
Therefore, since the shielding plates NH3-10 are formed at equal intervals as described above, the opening of the water discharge hole on the inflow chamber side is repeatedly shielded with the rotation of the water turbine. Then, the washing water passes through the inflow-chamber-side opening only while the inflow-chamber-side opening is not shielded by the shielding plate, and is discharged from the water discharge hole.
For this reason, the washing water is discharged from the water discharge hole in an intermittent flow state in which the flow is divided by the shielding plate at the opening of the water discharge hole on the inflow chamber side.

On the other hand, the rotational force of the turbine is determined by the flow rate of the wash water into the inflow chamber (the wash water velocity), and this flow rate defines the rotational speed of the turbine. Therefore, the shielding period of the inflow-chamber-side opening by the shielding plate, that is, the intermittent period of the washing water intermittently caused by the division of the flow, is determined by the rotation speed of the water turbine, that is, the washing water speed. Therefore, the cleaning nozzle WN of this reference example
By adjusting the washing water speed at the time of supplying the washing water to 3-1, the frequency determined by the above-described intermittent cycle can be set to the dead band frequency range described above. For this reason, according to the cleaning nozzle WN3-1, similarly to the above-described reference example and its modified example, the pulsating flow or the intermittent flow of the cleaning water discharge can realize the adjustment of the water force and the like at a low flow rate. In this case, if the inside diameter of the inflow chamber, the size of the shielding plate, the installation interval of the shielding plate, and the like are different between the first turbine NH3-8 and the second turbine NH3-9, the flow is divided as described above. The intermittent cycle of the washing water that is set to the intermittent flow can be made different between buttocks washing and bidet washing. For this reason, the frequency determined by the intermittent cycle can be changed between the buttocks cleaning and the bidet cleaning, so that the cleaning feeling at the time of each cleaning can be made different. For example, if the frequency of the bidet cleaning is set to be higher, the cleaning feeling of the bidet cleaning can be softer than that of the buttocks cleaning.

In the cleaning nozzle WN3-1 of this reference example,
As described above, in order to obtain the effect of adjusting the water force and the washing feeling by the intermittent flow of the washing water, an electric drive device such as a motor is not required. Therefore, a high power saving effect can be achieved as a whole device, and the configuration can be simplified. Further, since an electric wiring step to the nozzle head is not required and an electric driving device is not required, there are advantages in manufacturing such as reduction in the number of assembling steps and cost.

The cleaning nozzle WN3-1 may be configured so that the orifice has an outside air introduction passage in the middle of the path of each water discharge hole to perform air mixing. Further, the washing nozzle WN3-1 may be configured such that a motor for rotating the water wheel is incorporated in the nozzle head, and the rotation of the water wheel is controlled by the motor. In this case, since the above-mentioned intermittent cycle can be variably controlled irrespective of the washing water speed, it is possible to adjust the water force through frequency control of the intermittent flow without being affected by the washing water speed.

As shown in FIG. 108, the cleaning nozzle WN4-1 of the reference example is provided with a nozzle head NH4-1 in a watertight manner at the tip of a nozzle cylindrical body WN4-2. The nozzle head has an intermittent water discharge mechanism NH4-2 on its upper surface. In the following description, the cleaning nozzle WN
4-1 will be described as one for ass washing.

The intermittent water discharge mechanism NH4-2 cleans the continuous flow of washing water supplied from the head flow channel NH4-3, like the above-mentioned cleaning nozzle WN3-1, by the intermittent flow of the cleaning water. It discharges water as water. That is, the intermittent water discharge mechanism is provided with the cleaning water inflow chamber NH at the end of the head passage.
4-4 has a bottom plate NH4-5 and a water wheel NH4-6. The bottom plate allows the wash water flowing from the head flow path into the wash water inflow chamber to flow toward the peripheral wall of the inflow chamber as indicated by the arrow in the drawing. As shown in FIGS. 108 and 109, the water wheel is incorporated into the lower peripheral wall of the water wheel support NH4-7 on the upper surface of the nozzle head, and is inserted into the shaft NH4-8 at the center of the support. When the turbine support is fixed to the upper surface of the nozzle head in this state, the turbine becomes rotatable about the shaft inside the lower peripheral wall of the turbine support. This waterwheel is
A shielding plate NH4-9 covering the blade is provided on the upper surface.

As shown in FIG. 109, the water wheel support NH4-7 has notches NH4-10 at equal intervals on the lower peripheral wall. Therefore, the washing water that has flowed to the inner peripheral wall side of the washing water inflow chamber by the bottom plate NH4-5 passes through each notch and collides with the blade of the waterwheel NH4-6 to rotate this waterwheel. The washing water collides with the shield plate NH4-9 of the turbine from below, and pushes the turbine toward the lower surface of the turbine support. For this reason, the water turbine rotates with its upper surface in contact with the lower surface of the water turbine support. The waterwheel support is located at a position overlapping the shield plate of the waterwheel.
1, the water discharge hole is blocked or opened as the water turbine rotates. For this reason, the washing water is discharged from the water discharge port opened by the water turbine, so that attention is paid to one water discharge hole. An intermittent flow in which the flow is divided by the shielding plate in the hole is discharged from the water discharge hole. In the case where a plurality of water discharge holes are provided at equal intervals as in the present reference example, since the water discharge holes opened by the shielding plate sequentially move by the rotation of the water turbine,
The spouting of the washing water is sequentially switched to the spouting holes, and the spouting is performed in the intermittent flow state.

Even with the washing nozzle WN4-1, the inflow speed of the washing water defines the rotation speed of the turbine, so that the intermittent cycle of the intermittent flow due to the above-described division of the flow is the rotation speed of the turbine,
That is, it is determined by the washing water speed. Further, the switching cycle for switching to water discharge at the adjacent water discharge hole is also determined by the rotation speed of the water turbine, that is, the washing water speed. Therefore, at the time of supplying the cleaning water to the cleaning nozzle WN4-1 of this reference example, by adjusting the cleaning water speed,
Both the frequency determined by the above-mentioned intermittent cycle and the frequency determined by the above-mentioned switching cycle can be set in the above-mentioned dead band frequency range. For this reason, according to the cleaning nozzle WN4-1, similarly to the above-described reference example and its modification, the pulsating flow or the intermittent flow of the cleaning water can be used to realize a water pressure adjustment at a low flow rate or the like. In this case, despite the fact that the water discharge holes of the wash water are sequentially switched on the formation circumference of each water discharge hole,
It cannot be recognized that water is sequentially discharged from each of the water discharge holes, and it feels as if water is continuously discharged from each of the water discharge holes. For this reason, it is possible to change the water force at that time by adjusting the intermittent frequency while giving a feeling that water is continuously discharged over a wide area.

In the cleaning nozzle WN4-1 of this reference example,
In order to obtain the effect of adjusting the water force and the washing feeling by the intermittent flow of the washing water as described above, since an electric drive device such as a motor is not required, the same effect as that of the reference example shown in FIG. 107 can be obtained. it can. This cleaning nozzle WN4
Even if the value is -1, the rotation of the water turbine can be controlled by a motor. In this case, since the above-mentioned intermittent cycle can be variably controlled irrespective of the washing water speed, it is possible to adjust the water force through frequency control of the intermittent flow without being affected by the washing water speed. In addition, when the water wheel is rotated by a motor and the tail water discharge holes NH4-11 provided at equal intervals in the water turbine support NH4-7 are formed obliquely so as to be inclined outward, water is discharged from the water discharge holes. The water discharge direction of the cleaning water is three-dimensionally deflected independently of the flow rate of the cleaning water. Therefore, in this case, the water wheel, the motor for driving the water wheel, and the water discharge hole inclined as described above function as the “water discharge deflection means” according to the present invention.

Next, another reference example will be described. FIG.
10 is a schematic cross-sectional view of a main part of a cleaning nozzle WN5-1 included in a local cleaning device of another reference example. In the following description, the same member names and the same reference numerals will be used as described above. The cleaning nozzle NH5-
1 will be described as one for ass washing.

In the cleaning nozzle NH5-1 of this reference example, when air is forcibly mixed into the cleaning water and the water is discharged, the pulsating flow or the intermittent flow of the cleaning water is discharged by periodically changing the air mixing amount. There is a feature in that. That is, as shown in FIG. 110, the cleaning nozzle NH5-1 has a tail water discharge port NH5-2 at the nozzle tip, and the nozzle flow path N
Water is supplied through H5-3. An air mixing chamber NH5-4 is formed below the water discharge hole opening. In this air mixing chamber, the nozzle flow path is formed by a porous pipe NH5-5 made of a material such as resin, metal, and ceramic. Have been.

The air mixing chamber NH5-4 is provided with an air passage NH5.
It is connected to the pneumatic feed mixing unit NH5-7 via -6. As shown schematically in the drawing, this air pressure feeding / mixing unit sends air to the air mixing chamber while periodically varying the air flow rate or at a fixed set flow rate.
The air pressure mixing unit mixes air into the cleaning water through the porous pipe NH5-5 in the air mixing chamber. The porous pipe mixes air as fine bubbles into the cleaning water passing therethrough due to its porous nature. Therefore, in combination with the pressure feeding from the air pressure feeding / mixing unit, it is possible to mix air up to four times in volume ratio with respect to the washing water.

The above-described pneumatic feeding and mixing unit may be constituted by using a variable displacement type air pump or by using a constant displacement or variable displacement type air pump and a flow regulating valve arranged downstream thereof. it can. Alternatively, the air pump can be configured using these air pumps and an on-off valve arranged downstream of the air pump to open and close the pipeline. In order to pump air while periodically fluctuating the air flow rate in the air pressure mixing unit configured as described above, the flow rate may be periodically fluctuated by controlling the rotation speed of the air pump, or the line may be controlled by a flow regulating valve. May be changed periodically in the range of 0 to 100%, or may be changed periodically in the range of 10 to 100%.
In the case of an on-off valve, the opening and closing of the pipeline may be repeated periodically. In this case, if a positive displacement air pump is used as the air pump, the air supply / stop / repeating is repeated in accordance with the operation of the air pump. In such a configuration, when the effective area of the pipeline is set to 0 by the flow control valve, the pipeline is shut off by the on-off valve, or the operation of the positive displacement air pump is stopped, the washing water is cut off. Situation, i.e., only air comes out of the spout. Therefore, it is possible to adopt a water discharge mode in which the mixed air becomes a sandwich in a state of water, air, water, air, etc. without being finely mixed with water. This water discharge form has almost the same behavior as the above-described water discharge form of intermittent flow of wash water. Because of this, the apparent volume increases due to air mixing, the flow rate of the cleaning water is increased, and the water is sandwiched by air, so that the cleaning water becomes a water mass and is discharged.
The same effect can be expected as the washing water spouting of the wave flow.

In the cleaning nozzle NH5-1, when water is supplied to the nozzle from the cleaning water supply unit NH5-8 in a state where the air supply from the air supply mixing unit NH5-7 is stopped, the tail water discharge port NH5-2 is provided. , The washing water can be spouted in a continuous flow. Also, the pneumatic feed mixing unit NH5-7
When water is supplied to the nozzle with the air pressure feeding from the nozzle set to a constant set flow rate, the washing water containing bubbles mixed at a substantially constant ratio can be in a continuous flow state. In other words, it is possible to selectively use the flushing water that has been mixed with air and the flushing water that contains only the flushing water. And water can be saved by the amount of air mixing. In addition, by adjusting the setting of the amount of mixed air and / or adjusting the flow rate of the washing water, the washing water mixed with air at various ratios can be discharged in a continuous flow state, depending on the amount of mixed air and the flow rate. A feeling of washing and water force can be obtained.

In the cleaning nozzle NH5-1, air is fed under pressure while periodically varying the air flow rate, and is mixed into the cleaning water. The washing water is a part of which is periodically repeated. In the part where the air mixing amount is dense, the flow rate of the washing water is increased by the amount of air mixing, and in the sparse part, the flow velocity does not increase as much as the dense part. The portion where the air mixing amount is high and the flow speed is high catches up with the sparse and low flow speed portion and unites with this. This phenomenon is not different from the phenomenon described with reference to FIG.
Moreover, in this reference example, when the air is pumped while periodically varying the air flow rate, the variation frequency determined by the variation cycle is set within the dead band frequency range described above. As a result, the washing water spouting in this reference example becomes a pulsating flow or intermittent flow spouting of the washing water in accordance with the state of the periodic fluctuation of the air flow rate. It is the same as the one we aimed for. That is, the cleaning water spouting in this reference example is as shown in FIG.
Therefore, according to the reference example, it is possible to achieve the same effect as the above-described reference example, that is, to improve the water-saving effect and to set various washing feelings and water forces. In this reference example, diversification of the cleaning feeling can be brought about by adjusting the fluctuation width at the time of the periodic fluctuation of the air flow rate and / or the flow rate of the cleaning water. That is, even if the flow velocity is reduced due to a shortage of water, the water force can be maintained or the strength can be adjusted by adjusting the fluctuation width during the air pressure feeding.

Next, another embodiment will be described. FIG.
11 is a block diagram illustrating a water channel configuration included in a local cleaning device KS6-1 according to another embodiment.

The local cleaning device KS6-1 of this embodiment is
It is characterized in that the washing water spouting by the oscillating rotation of the spouting hole realized in the first embodiment and the washing water spouting by the pulsating flow realized in the first reference example can be executed individually or simultaneously. That is, as shown in FIG. 111, the local cleaning apparatus of this embodiment has the cleaning nozzle WN1-1 of FIG. 4 in the water channel configuration of the reference example of FIG. Therefore, this local cleaning device has the following advantages.

(1) The wave generation device WP2-8 of the wave generation unit WP2-3 may be stopped to supply washing water downstream thereof. In this aspect, since the washing water passes through the stopped wave generation device as described above, the washing nozzle WN1-1 is supplied with the washing water in a continuous flow. Such a water supply state is not different from the reference example. Therefore, the local cleaning device KS6 of this embodiment
In the case of -1, pseudo-conical water discharge from the washing nozzle WN1-1 by pseudo-oscillating rotation of the buttocks movable body NH1-9 and bidet movable body NH1-11 (FIG. 22). , See FIG. 23). In this case, the same effect as the above embodiment can be obtained. As an example, when the pseudo-oscillating rotation of the movable body is caused, the duty ratio variable control and the frequency variable control or both controls are used to set the strength of the water without depending on the flow control result of the washing water by the flow control valve. In addition, it is possible to diversify the washing feeling. In the case where the washing water is spouted by the pseudo swinging rotation of the movable body, the washing nozzle WN1-1 can be supplied with a continuous flow of washing water by bypassing the wave generation unit WP2-3. The pressure loss at the time of supplying the washing water can be suppressed.

(2) First, the buttocks movable body NH1-9 and the bidet movable body NH1-11 are set in the free state by de-energizing all the electromagnetic coils, or by simultaneously exciting all the electromagnetic coils. The movable body is brought into a state of being attracted to the coil. In this state, a mode can be adopted in which the pulsating flow cleaning water in the dead band frequency region generated by the wave generation device WP2-8 of the wave generation unit WP2-3 is supplied to the cleaning nozzle. Since this water supply mode is not different from the above-described reference example, pulsating flow of cleaning water can be discharged from the cleaning nozzle WN1-1 just like the reference example. Therefore,
By using variable duty ratio control and variable frequency control when generating pulsating flow, or by using both controls, the strength of the water force can be set and the feeling of cleaning can be diversified without depending on the flow control result of the cleaning water by the flow control valve. For example, the same effect as that of the reference example can be obtained. In both water supply modes, it is possible to naturally improve water saving efficiency and reduce the capacity of the heater.

In this case, if the above-described pulsating flow water discharge is performed with the movable body in the free state, the following advantages can be obtained. The flange portion NH1-15 and the cylindrical portion NH1-16 supporting the movable body are
As described above, it is formed of an elastic material exhibiting a deformation restoring property. Therefore, the frequency of the pulsating flow can be controlled so that the frequency of the pulsating flow resonates with the vibration characteristics of the movable member in the free state determined by the degree of elasticity of these members, the weight of the movable member, and the like. In this case, the pressure fluctuation width of the pulsating flow can be emphasized by the resonance vibration of the movable body having the water discharge hole itself, and a sharp stimulus can be provided. Further, since the fluctuation range of the pulsating flow can be reduced, power can be saved accordingly.

(3) The pulsating flow washing water in the dead band frequency region generated by the wave generating device WP2-8 of the wave generating unit WP2-3 is supplied to the washing nozzle, and the above-mentioned quasi-oscillating rotation of the movable body is performed. The cleaning water can be spouted in a pseudo-conical spouting form. In this case, the flow rate adjustment by the flow regulating valve is complemented by the duty ratio variable control and the frequency variable control or the both control (hereinafter, this control is referred to as movable body control) at the time of pseudo swing rotation of the movable body. Duty ratio variable control and frequency variable control or both of these controls (hereinafter, this control is referred to as pulsating flow control) when generating a pulsating flow can be achieved. Therefore, even under a stricter flow rate of washing water at a lower flow rate, the user can achieve a desired washing feeling and water force by supplementing the flow rate adjustment by the movable body control and the pulsating flow control. As a result, the effectiveness of further water saving can be enhanced. In addition, there are the following advantages.

At the time of massage washing for facilitating defecation using the movable body control, the movable body is supplied with pulsating flow cleaning generated by the pulsating flow control. In this way, the change in the washing sensation based on the change in the washing area (see FIG. 36) by the movable body control and the change in the cleaning sensation in the hardware and software based on the manner of the pulsation by the pulsation flow control are more effective in promoting convenience. is there. When spotting and widening the cleaning area using the movable body control (see FIG. 34), the movable body is supplied with the pulsating flow cleaning generated by the pulsating flow control. In this way, in each cleaning area changed by the movable body control,
It is possible to receive a change in the feeling of hard / soft washing based on the manner in which pulsation is generated by the pulsating flow control, and the feeling of washing is further diversified. Further, the monotonous feeling at the time of spot-wide cleaning is more effectively eliminated. When the waste OB around the local area is peeled off by spotting and widening the cleaning area using the movable body control (see FIG. 37), the movable body is supplied with the cleaning of the pulsating flow generated by the pulsating flow control. In this way, the model water discharge water column RT that changes according to the movable body control can have a strong and weak change in water force based on the manner in which the pulsation is generated by the pulsating flow control. Therefore, the peeling effect of the waste OB is enhanced. At the time of the fluctuation cleaning due to the irregular change of the cleaning area using the movable body control, the movable body is supplied with the cleaning of the pulsating flow generated by the pulsating flow control. In this way, the prediction of the change in the cleaning area (see FIG. 40) in which the cleaning area changes irregularly due to the control of the movable body is made more in accordance with the change in the strength of the water and the change in the feeling of cleaning based on the manner in which the pulsation occurs. Because it is difficult, it is possible to more effectively promote consent. Further, if the fluctuation cleaning by the pulsating flow control (see FIG. 84) is performed in addition to the fluctuation cleaning by the movable body control, it becomes more difficult to predict the transition of the cleaning state, which is advantageous for promoting the bowel movements and developing the enema effect. In the move cleaning using the movable body control (see FIGS. 32 and 48), the movable body is supplied with the pulsating flow cleaning generated by the pulsating flow control. In this manner, the cleaning during the move cleaning is performed based on the change in the cleaning feeling based on the change of the cleaning area by the movable body control according to the nozzle position, and the change in the strength of the water and the change in the cleaning feeling based on the pulsation expression by the pulsating flow control. The feeling is diversified, and the monotonous feeling of local cleaning can be more effectively eliminated.

Next, a modification of the local cleaning apparatus of the above embodiment will be described. The local cleaning device of this modification is characterized in that the cleaning water is discharged to a cleaning point desired by the user. FIG. 112 shows a local cleaning device KS of this modification.
FIG. 113 is an explanatory diagram showing a schematic configuration of 6-2, FIG. 113 is an explanatory diagram for explaining a control method at the time of discharging cleaning water to a cleaning point, and FIG. 114 is a cleaning point instruction panel KS6- in another modified example. FIG. 5 is an explanatory diagram for explaining No. 5;

As shown in FIG. 112, the modified local cleaning apparatus KS6-2 has a rotary knob KS6-4 for indicating the cleaning points XA, XB, XC on the sleeve KS6-3 of the main body. The cleaning points XA, XB, XC are shown in FIG.
Correspond to the installation positions of the electromagnetic coils for exciting each movable body shown in FIG. For example, in the case of the bidet movable body NH1-11,
The cleaning point XA is connected to the electromagnetic coil NH1-33a by XB
Is the electromagnetic coil NH1-33b, XC is the electromagnetic coil NH
1-33c. Electronic control unit CT6-2
Reads the rotation operation amount of the rotary knob, and on the locus on which the schematic water spouting water column RT (see FIG. 22) can be applied by the local cleaning device, where the user wants to apply the water column Judge. For example, if the rotary knob matches the cleaning point XA, it is determined that the local skin XAN corresponding to the XA is to be cleaned. In addition,
When the rotary knob is operated in the middle of each washing point, the washing point desired by the user is determined based on the deviation from any one of the washing points.

[0404] The electronic control unit CT6-2, which has determined the washing point in this way, performs the quasi-oscillating rotation of the movable body by the movable body control and the generation of the pulsating flow by the pulsating flow control as follows. Hereinafter, for convenience of explanation, it is assumed that the cleaning point is XA.

That is, when the movable body is oscillated and rotated at the pulsation frequency, when the movable body is tilted by the suction of the electromagnetic coil corresponding to the washing point, the pulsating flow of washing water is discharged from the water discharge hole of the inclined movable body. Let the water be spouted. In this manner, the pulsating flow of the washing water can be discharged to the washing point desired by the user to wash the washing point.

By the way, in a device such as the wave generating device WP2-8 which requires driving of a plunger or the like, a response delay occurs in driving the plunger. Therefore, the electronic control unit CT6-
2 is the response delay time ta as shown in FIG.
In consideration of this, the pulsation flow is generated by driving the wave generation device WP2-8 faster by this time ta. In this manner, the cleaning can be performed by accurately discharging the schematic water discharge column RT at the cleaning point desired by the user. In this case, the above-mentioned response delay time t
“a” may be written in the ROM of the electronic control unit, and the delay time ta may be read in the pulsating flow control. The delay time ta can be variably set by a dedicated slide switch or the like, and can be adjusted at the time of maintenance or inspection or at the time of product shipment.

[0407] Instead of the above-mentioned rotary knob KS6-4,
Cleaning point instruction panel KS6 as shown in FIG. 114
-5 can be used. This pointing panel has a so-called matrix switch on the panel surface, and generates pointing position data at a fingertip by using the capacitance of a human body. The electronic control unit determines the washing point based on the designated position data. The instruction panel may be provided on the sleeve of the remote control device or the main body. Also, instead of such an instruction panel, a joystick or the like may be used to instruct a washing point.

Next, another modification of the local cleaning apparatus of the above embodiment will be described. This modified example is a washing water spouting (hereinafter, referred to as “washing water”) by the swinging rotation of the spouting hole realized in the first embodiment.
It is characterized in that sequence control is performed by combining washing water spouting with pulsating flow (hereinafter referred to as pulsating spouting) realized in the reference example in the washing operation. FIG. 170 is an explanatory diagram showing an example of sequence control of the pulsating water discharge and the oscillating rotary water discharge. An operation switch (not shown) for instructing automatic cleaning is provided on the remote control device, the sleeve of the main body, or the like, and when the user operates the switch, the cleaning shown in FIG. 170 is automatically performed. For example, each operation switch (auto 1 switch, auto 2 switch) for executing auto washing 1 and auto washing 2 shown in FIG.
Switch) is provided as a switch for a cleaning operation independent of other cleaning switches, and when this switch is operated, these automatic cleanings may be operated. In this case, each automatic cleaning is performed only when the above-mentioned auto switch is operated.

Here, the illustrated automatic cleaning will be described starting with automatic cleaning 1. In the following description, the cleaning operation period is divided into cleaning periods in time series, and each cleaning period is referred to as a step. Auto wash 1
Is a mode assuming local cleaning after defecation, and in Step 1 at the start of the cleaning operation, the flow rate is set to a small value (for example, 200 cc / min), and water is discharged with a weak water force by oscillating rotary water discharge. This allows the user to start using the apparatus without worrying about suddenly receiving strong flush water. Subsequently, the washing proceeds to step 2, and the flow rate is increased while maintaining the form of the oscillating rotary spout (for example, 500 cc /
min), washing is performed from the local peripheral portion by oscillating rotating water spouting. At this time, as shown in FIG. 37, control may be performed so that dirt adhering to the local portion is collected at the central portion. Stimulation from the local periphery can amplify the stimulus more finely for delicate local areas. Next, the process proceeds to step 3 in which the form of water discharge is changed to pulsating water discharge, and the central part is thoroughly washed by the pulsating water discharge. As for the feeling of washing, since the local part is used to the stimulation, a comfortable feeling of stimulation and feeling of washing can be obtained. Finally, the process proceeds to step 4, in which the water discharge mode is returned to the initial swing rotation water discharge, and the dirt scattered on the local peripheral edge by the swing rotation water discharge is washed out. Step 4 serves as a finishing wash. Of course, the combination elements and order of each cleaning are not limited to this example, and it goes without saying that the cleaning elements may be freely set without departing from the concept of cleaning by combining the characteristics of each cleaning. In addition, the oscillating rotary water discharge in step 2 and step 4 illustrated above may be changed by changing the rotation frequency, the cleaning area, and the like.

[0410] The auto-cleaning 2 is a mode assuming the promotion of defecation during defecation. In this automatic cleaning 2, in step 3 following the above steps 1 and 2, the flow rate control for stabilizing the flow rate in the pulsating discharge as shown in FIG. Multiply. In this case, the stimulus to the central part of the local area is increased by the pulsating water discharge as the flow velocity increases. In the last step 4, since the flow velocity is further increased with the pulsating spout, the washing water enters the anus and has an enema effect. In each cleaning step of each automatic cleaning, the cleaning mode may be changed such that the illustrated rotationally oscillating water is changed to pulsating water. Further, the time spent in each step may be the same or may be longer or shorter.

Also, in order to continuously carry out these automatic washings, an automatic washing setting switch is provided, and while the automatic washing setting is turned on by this switch, each of the ass washing, the soft washing and the bidet washing is performed. The cleaning is performed in a sequence in the automatic cleaning 1 or the automatic cleaning 2 described above. Then, if the setting of the automatic cleaning is turned off, the normal butt cleaning, soft cleaning,
Each bidet wash is executed in response to a button operation.

[0412] The automatic cleaning is not limited to one type, and it is more preferable to provide a plurality of types. For example, as shown in FIG. 170, an automatic washing 1 and an automatic washing 2 are provided, each of which can be used for washing after defecation and washing before defecation. As can be seen from FIG. 170, the cleaning is suitable for each purpose (removal of dirt in the automatic cleaning 1, promotion of defecation in the automatic cleaning 2).

[0413] It is preferable to provide a plurality of automatic washings according to gender, age, personal preference, and the like. In addition, it is more preferable that the contents of the automatic cleaning be set not only by the manufacturer but also freely by the user. By providing a means for the user to individually set the contents of the automatic cleaning and a means for storing and recalling the set contents, the user can select the most preferable cleaning mode for himself / herself. Needless to say, the present invention is not limited to the posterior cleaning, and the bidet cleaning may employ an automatic cleaning in accordance with the bidet cleaning. Further, each of the above-described steps may be set as a switch so that the user can use each step for a desired time interval.

FIG. 115 is an explanatory view showing a local cleaning apparatus provided with a cleaning nozzle WN20 according to another reference example. The local cleaning device includes a cleaning water supply unit WP20-1, a heat exchanger TH20-2, a cleaning nozzle WN20, and a control unit CT.

P20-12 and a flow control valve WP20-13. The water pump WP20-11 is attached to the water pump WP20-11 when the tap water pressure for discharging is insufficient or when the tap water pressure is not used. Further, the washing nozzle WN20 is provided at the tip of the water passage in the water discharge swinging means WN20-41. The water discharge rocking means WN20-41 includes a rotation motor WN20-41a and a rotation motor WN20-41.
and a rotating disk WN20-41b driven by a, and has a water discharge hole WN20-41c at a position eccentric to the rotation axis of the rotating disk WN20-41b. The control unit CT20-6 includes a cleaning water supply unit WP

The path of the washing water of the washing nozzle WN20 will be described. When the washing water is supplied from the washing water supply means WP20-1 to the heat exchanger TH20-2, the heat exchanger TH20-2.
Is changed into warm water, flows into the cleaning nozzle WN20, is discharged from the water discharge holes WN20-41c, and local cleaning is performed. The trajectory control unit control means CT20-64 of the control unit CT20-6 controls the water discharge rocking means WN20-41. The water discharge rocking means WN20-41 includes a rotating disc W
By rotating the N20-41b, the rotating disk W
The washing water is spirally discharged from a water discharging hole WN20-41c provided at a position eccentric to the rotation axis of N20-41b. In this case, if the water discharge holes WN20-41c are formed so as to be inclined outward, the water discharge direction of the wash water discharged from the water discharge holes will be three-dimensionally deflected independently of the flow rate of the wash water. Therefore, in this case, the rotating disk WN20-41b and the rotating motor WN20-4 are provided.
1a and the water discharge hole inclined as described above function as the "water discharge deflection means" in the present invention, and if the motor control device performs on / off control of the rotation motor WN20-41, the motor control device is cleaned. It functions as "fluctuation inducing means" for controlling the area fluctuation so that the human body does not recognize it. This point is the same as the cleaning nozzles WN22, 24, 26, described below.
28, 30, 38, 44, 58, 60, 61, 96, 9
The same applies to the cleaning nozzles 7 and 120. Even these cleaning nozzles can be controlled so that the fluctuation of the cleaning area is not recognized by the human body through on / off control of the motor, and furthermore, they have a function as “fluctuation inducing means”.

FIG. 116 is a configuration diagram showing a cleaning nozzle WN22 according to another reference example. FIG. 116 (a) is a top view, and FIG. 116 (b) is a cross-sectional view from the side.

[0416] The washing nozzle WN22 is connected to the heat exchanger TH22.
-51, connected to the flow control water shutoff valve WP22-53. The water discharge part WN22-3 is provided with a water discharge hole WN22-31.
b, water passages WN22-32b, and the like.
The water discharge holes WN22-31b are configured by arranging a plurality of holes in a row in the radial direction from the center of the disk. The water discharge section drive mechanism WN22-4 includes a motor WN22-
41d, a shaft WN22-42b and the like. Water discharge part WN22-3 and water discharge part drive mechanism WN22-4
And are integrally formed via a shaft WN22-42b. Seal part WN22-34 and seal part WN
Reference numerals 22-35 are attached so that the washing water does not leak from other than the water discharge holes WN22-31b.

[0417] The motor WN22-41d of the water discharge section drive mechanism WN22-4 is controlled by the predetermined trajectory control means CT22-2. That is, the predetermined trajectory control means CT22
-2 controls the cleaning water at a predetermined locus and at a predetermined frequency by rotating the motor WN22-41d by controlling the power supply to the motor. With the configuration in FIG. 116, the motor WN22-
When 41d rotates, the water discharging section WN22-3 also rotates, so that the cleaning water discharged from the water discharging holes WN22-31b is discharged while drawing a predetermined trajectory. In this case, the water discharge hole WN
If 22-31b is formed obliquely so as to be inclined outward,
The direction of the flush water spouted from the spout hole is three-dimensionally deflected independently of the flow rate of the flush water. Therefore, in this case, the water discharging section WN22-3, the motor WN22-41d for rotating the water discharging section WN22-3, and the water discharging hole inclined as described above function as "water discharging deflection means" according to the present invention,
The motor control device functions as “fluctuation inducing means”.

FIG. 117 is an explanatory view showing a cleaning nozzle WN24 according to another reference example. FIG. 117 (a) is a sectional view, and FIG. 117 (b) is a plan view showing the movement of the water discharge holes WN24-4b. The cleaning nozzle WN24 has a shaft WN24-6a.

An eccentric cam WN24-51c eccentric with respect to 4-6a is fixed. Further, the eccentric cam WN24-51c is provided separately from the eccentric cam WN24-51c.

Connected through.

In the configuration of the cleaning nozzle WN24 in FIG. 117, when the drive motor WN24-51a is driven, the eccentric cam WN24-51c rotates around the axis WN24-6a of the drive motor WN24-51a.
24-4a and the immovable water passage WN24-3a are connected by an elastic joint WN24-2, and the eccentric cam receiver WN24-42 contacts the eccentric cam WN24-51c separately. Therefore, the eccentric cam receiver WN24-4
2 causes a slip with respect to the eccentric cam WN24-51c,
It rotates or substantially rotates without rotating around the axis WN24-6a. At this time, the joint WN24-2 is wound around the eccentric cam receiver WN24-42, or the drive motor WN2
4-51a does not move.

In the cleaning nozzle WN24, if the drive motor WN24-51a is driven and the cleaning water is supplied, the eccentric cam receiver WN24-42 becomes the shaft WN24-6a.
The spout hole WN24-4b also rotates or substantially rotates without self-rotation around the axis WN24-6a without rotating around the axis, and the washing water is spouted while rotating or substantially rotating. You. As a result, the wash water discharged from the water discharge holes WN24-4b has a predetermined trajectory that has been rotated or substantially rotated. As described above, the cleaning nozzle WN24 in the present reference example can move the water discharging hole WN24-4b and the cleaning water after water discharging on a predetermined trajectory without providing a seal portion around the water discharging hole WN24-4b. In this case, if the water discharge holes WN24-4b are formed obliquely so as to be inclined outward, the water discharge direction of the wash water discharged from the water discharge holes is three-dimensionally deflected independently of the flow rate of the wash water. Therefore, in this case, the eccentric cam receiver W
The N24-42, its drive motor WN24-51a, and the water discharge holes inclined as described above function as "water discharge deflection means" according to the present invention, and the motor control device functions as "fluctuation inducing means".

Also, the cleaning nozzle WN24 in FIG.
Moving water channel WN24-4a and immovable water channel WN24-3a
Since there is no seal portion between them, there is no loss due to frictional resistance of the seal portion, and it is not necessary to make the drive motor WN24-51a larger than necessary, and a compact washing nozzle can be obtained. Further, since there is no seal portion, there is no problem that durability of packing or the like of the seal portion becomes a problem.

In particular, the water discharge holes WN24-4b are made smaller,
When performing water-saving cleaning at an increased water discharge speed, the pressure of the cleaning water in the water passage is high, so that there is a problem due to the use of the seal portion, that is, a problem such as a loss due to frictional resistance and durability of the packing of the seal portion. Great effect on

FIG. 118 shows a cleaning nozzle WN26 according to another embodiment. FIG. 118 (a) is a sectional view, and FIG.
(B) is an oblique perspective view. The cleaning nozzle WN26 includes a water discharging unit WN26-4. The water discharge section WN26-4 is
Water inlet WN communicated via passage WN26-4c
26-4a, water discharge hole WN26-4b, and eccentric cam receiver W
N26-4d, and packing WN26-10
, And is freely supported by the support portion WN26-52 of the cleaning nozzle WN26, and can move around the support portion WN26-52 as a fulcrum. Eccentric cam receiver WN26-4
d is in contact with the eccentric cam WN26-20b, and the eccentric cam WN26-20b
0 and is eccentrically joined to the axis of rotation shaft WN26-20a. The water supply port WN26-2a is separated from the water supply port WN26-4a via a gap so that the discharged cleaning water is directed into the water inlet WN26-4a. In addition, the support part WN
The packing WN26-10 at 26-52 has a
It is preferable to have an appropriate flexibility so as to support the movement of N26-4 without hindering the movement. This packing WN2
6-10 also has a function of preventing water from entering the inside of the washing nozzle, but if there is no problem even if water enters the inside of the washing nozzle, the packing WN26-10 may not be particularly necessary.

In the cleaning nozzle WN26, by supplying electricity to the water discharge section drive motor WN26-20, the water discharge section WN2
6-4, with the support portion WN26-52 as a fulcrum, a water supply port WN26- corresponding to the amount of eccentricity of the eccentric cam WN26-20b.
A conical movement is performed, which is a relative displacement operation with respect to 2a. As a result, the cleaning water discharged from the water discharge holes WN26-4b draws a conical spiral trajectory, so that a wide range of cleaning can be performed at the portion to be cleaned by discharging water in an annular trajectory. That is, since the cleaning nozzle WN26 takes the form of water discharge as shown in FIG.
Spout section WN26-4 having the water spout section 26-4b, an eccentric cam and a spout section drive motor WN2 for driving the spout section WN26-4 as described above.
6-20 functions as the "water discharge deflection means" in the present invention, as in the first embodiment. Then, the motor control device functions as “fluctuation inducing means”. In addition, water inlet WN2
6-2a and the water inlet WN26-4a are isolated through a gap, and the washing water discharged from the water inlet WN26-2a is
During operation of the water discharge section WN26-4, the water inlet WN26-
By adopting a structure in which the water inlet WN26-4a is arranged so as to face the inside of the water supply section 4N, the water supply section WN26-2 and the water discharge section WN are provided.
The connection of the water channel of N26-4 can be performed in a non-contact manner. Thus, the water supply unit WN26-2 and the water discharge unit WN26
-4, without the connection of the water channel, and by performing only a wide range of cleaning with only a small operation of the water discharge section WN26-4, the driving force required for the motor is extremely small, and the noise and vibration during the water discharge cleaning operation are reduced. In addition, noise and vibration caused by the operation of the water channel connection part can be eliminated, and a highly reliable and compact washing nozzle can be realized. In addition, a wide range of cleaning can be performed with only a slight operation of the water discharge section, so even when driven at high speed,
Without increasing the vibration and noise generated by driving,
It is easy to increase the moving speed of the predetermined trajectory of the washing water, to change the speed from a low speed to a high speed, and to quickly start up to a high speed. Furthermore, since the intermittent cycle at which the cleaning water is applied locally is determined by the moving speed of the cleaning water, when used for cleaning the human body, moving the cleaning water at a high speed can provide a continuous and soft feeling of cleaning. On the other hand, if the washing water is moved at a low speed, a strong washing feeling with intermittent stimulation can be obtained. For this reason, the washing feeling can be changed over time without changing the flow rate of the washing water, and it is possible to easily correspond to various tastes of the washing feeling. Furthermore, since the instantaneous water discharge amount can be reduced, the temperature control of the heat exchanger that makes the washing water warm can not follow the increase or decrease of the instantaneous water discharge flow rate, and even if the washing feeling is made variable, a stable hot water temperature can be obtained. Water can be discharged.

Also, the water inlet WN26-2a and the water inlet WN
26-4a is isolated through an air gap, and the water supply port WN26
-2a has a structure in which the water inlet WN26-4a is arranged so as to face the inside of the water inlet WN26-4a during the operation of the water discharging unit WN26-4, and therefore, the cleaning water in the cleaning nozzle WN26 When there is a place communicating the space WN26-11 in which the water discharge section WN26-4 is arranged and the outside of the cleaning nozzle WN26, when the cleaning water discharged from the water supply port WN26-2a enters the water inlet WN26-4a,
Air can be entrained by the ejector effect and air bubbles can be mixed in the washing water. As a result, bubbles can be mixed into the wash water without the need to provide a bubble mixing means separately from the water discharging operation device. As a result, it is possible to realize a highly reliable cleaning nozzle having a small size and a small number of parts, and it is possible to enhance the cleaning power, particularly when used for cleaning a human body. In this case,
By forcibly sending air into the space WN26-11 using an air pump, air bubbles can be mixed in the washing water.

FIG. 120 shows a cleaning nozzle WN30 according to another reference example. FIG. 120 (a) is a sectional view, and FIG.
(B) is a perspective view. The cleaning nozzle WN30 has a water discharge hole whose predetermined locus is a repetition of forward / reverse inversion movement.

In FIG. 120, the cleaning nozzle WN30
Is connected to a rotating shaft WN30-51b projecting from the drive motor WN30-51a.
The crank disk WN30-51d is provided integrally with the crank disk 51b. The crank disk WN30-51d is separately connected to one end of the connecting rod WN30-51e at the connecting portion WN30-A. Another end of the connecting rod WN30-51e is separately connected to the reversing disc WN30-43 at a connecting portion WN30-B. Since the connecting portions WN30-A and B are separately connected, slippage occurs and the crank disk W
If N30-51d rotates about axis WN30-6b, it has a crank mechanism. In addition, the reversing disc W
N30-43 is a movable water passage WN30-4a and a water discharge hole W
N30-4b. In addition, mobile waterway WN
30-4a and the immovable water passage WN30-3a are connected by an elastic joint WN30-2.

The drive motor WN30-5 having the structure shown in FIG.
1a, the crank disk WN30-51d
Can be rotated in one direction, and the crank disk W
Despite the unidirectional rotation of N30-51d, the forward / reverse reversing disk WN30-43 repeats reversing movement around the axis WN30-6a in the forward and reverse directions by the crank mechanism via the connecting rod WN30-51e. Reversing disc WN3
0-43 is a forward / reverse reversal movement, so the joint WN30-2
May be unnecessarily twisted, blocking the water passage and impeding water flow, or the joint WN30-2 may be replaced by the reversing disc WN30.
There is no wrapping around -43 or the drive motor WN30-51a does not move.

Therefore, if the drive motor WN30-51a is driven to discharge the washing water, the forward / reverse reversal disk WN30
-43 repeats the forward / reverse inversion movement around the axis WN30-6a, so that the water discharge hole WN30-4b also repeats the forward / reverse inversion movement around the axis WN30-6a, and the cleaning water is forward / reverse in an arc shape or a substantially arc shape. Water is spouted while being inverted. Cleaning nozzle W
The movement of the water discharge hole WN30-4b of N30 and the predetermined trajectory of the wash water after water discharge is a repetition of forward / reverse inversion. Therefore, the moving water passage WN30-4a and the immovable water passage WN30-
Without providing a seal portion between the water discharge holes WN30.
-4b and the flush water after water discharge can be moved along a predetermined trajectory. In this case, if the water discharge holes WN30-4b are formed obliquely so as to incline outward with respect to the illustrated axis WN30-6a, even if the water discharge holes WN30-4b are shown in FIG. The motor control device functions as "variation inducing means".

Further, as another effect of the cleaning nozzle WN30, if the torsion of the joint WN30-2 is intentionally used, the cross-sectional area of the water passage in the joint WN30-2 can be changed with time. Not only can you perform a great variety of washing feelings,

FIG. 121 shows a cleaning nozzle WN32 according to another reference example. FIG. 121 (a) is a sectional view, and FIG.
(B) is a perspective view. FIG. 171 corresponds to FIG.
It is a principal part schematic sectional drawing of. The cleaning nozzle WN32 has a shaft W
A structure having a water discharge hole WN32-4b that moves along a predetermined trajectory without rotating around N32-6a is provided.

[0437] The cleaning nozzle WN32 is connected to the moving water passage WN3.
A ferromagnetic material WN32-52b is annularly arranged integrally with the movable water passage WN32-4a outside 2-4a. In addition, a gap WN32-5 is provided outside the ferromagnetic material WN32-52b.
2c, the electromagnetic coil WN3 as shown in FIG.
2-52a is arranged annularly. Electromagnetic coil WN32-
52a may be embedded in the cleaning nozzle WN32 due to its characteristics.
32-52a will not be flooded. Ferromagnetic material WN32
-52b and a plurality of electromagnetic coils WN32-52a are arranged in the circumferential direction. An elastic joint W is provided between the movable water passage WN32-4a and the immovable water passage WN32-3a.
N32-2. In addition, the spout hole WN32-
4b, moving water passage WN32-4a and eccentric cam receiver W
N32-52b is connected to the shaft WN3 via the joint WN32-2.
The structure is movable in the radial direction with respect to 2-6a.

In the configuration of the cleaning nozzle WN32 in FIG. 121, if the energization to the electromagnetic coil WN32-52a is controlled, the magnetic field generated by the electromagnetic coil WN32-52a causes
An attractive force or a repulsive force is generated between the moving water passage WN32-4a and the ferromagnetic material WN32-52b integrally formed. In this case, the ferromagnetic material WN32-52b integrated with the water discharge hole WN32-4b and the moving water passage WN32-4a is used.
Is movable through a joint WN32-2.
A gap WN32-52c in the radial direction with respect to N32-6a
Any movement is possible within the range.

Therefore, by controlling the energization of the electromagnetic coil WN32-52a and discharging the cleaning water, the water discharge hole WN32-52a is discharged.
4b rotates or substantially rotates or swings without rotating around the axis WN32-6a, and the washing water is discharged while rotating or substantially rotating or swinging. In this case, the water discharge hole WN
If 32-4b is formed obliquely so as to be inclined outward with respect to the illustrated axis WN32-6a, even the one shown in FIG. Then, the coil excitation control device functions as "fluctuation inducing means".

FIG. 122 shows a cleaning nozzle WN34 according to another reference example, FIG. 122 (a) is a perspective view from the side of the cleaning nozzle, and FIG. 122 (b) is a cross-sectional view of the cleaning nozzle WN34 from another direction. It is.

In FIG. 122, a water pump WN3 is provided in the cleaning nozzle WN34 in order from the upstream in the flow direction of the cleaning water.
4-2, the flow control valve WN34-3a and the rotary water discharging means WN34-4 are arranged in the water passage WN34-1a, and the cleaning water is discharged from the water discharging hole WN34-1b. The rotary water discharge means WN34-4 includes an impeller WN34-4a, an impeller casing WN34-4b, an impeller bearing WN34-4c,
It is composed of a seal part WN34-4d. However,
The presence / absence of the seal portion WN34-4d and the sealing property may be determined according to the usage state of the cleaning nozzle WN34. Further, the impeller WN34-4a and the water discharge hole WN34-1b are integrated. Further, the outlet WN34-31a of the flow rate control valve WN34-3a and the impeller WN34-4a are adjacent to each other.
-4a. The water pump WN34-2 and the flow control valve WN34-3a are separately and independently controlled by a control unit (not shown).

The cleaning nozzle WN3 according to the structure of FIG.
In 4, the washing water is pressurized by a water pump WN34-2, and is adjusted to a predetermined instantaneous discharge water amount by a flow control valve WN34-3a.
flows into a. Then, a part of the kinetic energy of the washing water is transmitted to the impeller WN34-4a, and the impeller WN3
Water is discharged from the water discharge hole WN34-1b while rotating 4-4a. Impeller WN34-4a and water outlet WN34-
1b is integrally formed, so that the impeller WN34-
When 4a rotates, the water discharge hole WN34-1b also rotates, and the cleaning water is discharged while rotating or substantially rotating.

If the capacity of the water pump WN34-2 is changed by the control unit and the flow rate control valve WN34-3a is controlled by the control unit so as to maintain a predetermined instantaneous discharge water amount, the instantaneous discharge water amount is kept constant. Despite that
The outflow kinetic energy from the wash water outlet WN34-31a can be changed, and the rotation speed of the impeller WN34-4a can be changed without depending on the instantaneous discharge water amount.

Therefore, the water discharge hole W in the cleaning nozzle WN34
Since only the vicinity of N34-1b is rotated using the kinetic energy of the cleaning water, the moving part is smaller than in the case where the cleaning nozzle WN34 itself is moved along a predetermined trajectory and the cleaning water is discharged while rotating or substantially rotating the cleaning water. In addition, there is almost no electric drive noise or vibration by the actuator, and it is very excellent in quietness and non-vibration. Furthermore, since only the vicinity of the water discharge hole WN34-1b is rotated by the rotary water discharge means WN34-4, it is easy to increase the rotation speed of the washing water or substantially the rotation speed, and by the effective dispersion of the washing water. , Water saving effect.

Also, since there is no direct electric drive part for rotating or substantially rotating the cleaning water, a very compact cleaning nozzle WN34 can be provided. Further, the durability of the electrically driven portion does not matter. Furthermore, unlike the case where power is transmitted by wiring, there is no leakage from wiring due to washing water,
Even when the washing nozzle WN34 itself is used in an environment where the washing nozzle WN34 is apt to be wet, the electric leakage does not become a problem. Furthermore, there is no need for electrical wiring work up to the nozzle tip.

[0446] Further, the number of rotations for rotating or substantially rotating the washing water and the instantaneous discharge water amount can be controlled independently of each other. It can be variably controlled from to high speed. Thus, when used as a washing nozzle for a local washing device, a washing head for washing a human body such as a shower head for washing a human body, a faucet outlet for hand washing, and a washing nozzle for washing a human body, it is possible to make the instantaneous discharge water amount constant and change only the feeling of washing. It is possible to sufficiently cope with various users' washing preferences despite the fact that the instantaneous discharge water amount is constant. In addition, since the instantaneous water discharge amount can be reduced, the temperature control of the heat exchanger that makes the washing water warm can not follow the increase or decrease of the instantaneous water discharge flow rate. Water can be spouted.

FIG. 123 shows a cleaning nozzle WN36 according to another reference example. FIG. 123 (a) is a plan view and FIG. 123 (b) is a side view. FIG. 123 (a)
As shown in the figure, the cleaning nozzle WN36 is connected to the outlet WN36.
The shape of the water passage WN36-1a from -31a to the inflow to the impeller WN36-4a is rapidly expanded, and the air passage WN36-1c is provided in the rapidly expanded water passage WN36-1a, or the water passage WN36- The air intake port WN36-1c is provided in a portion where the rapid expansion of 1a cannot be avoided. The air inlet WN36-1c mixes air by an ejector effect of the washing water. By performing air mixing in this manner, when saving water for washing, or when using as a washing nozzle for washing a human body such as a washing nozzle of a local washing device, a shower head for washing a human body, and a faucet spout for hand washing, It is possible to make the washing feeling soft.
The water pump WN36-2 and the flow control valve WN36
Independently controlling -3a, the kinetic energy of the washing water can be changed in spite of a constant instantaneous water discharge amount, so that the air mixing ratio by the ejector effect can be changed, and water saving can be made according to the use situation. It is possible to change the rate and obtain a more various washing feeling. When mixing air, forced mixing may be performed using an air pump.

Further, as shown in FIG. 123 (b), instead of the air inlet WN36-1c, the flush water downstream of the impeller WN36-4a in the flow direction of the flush water is rapidly expanded through the water passage WN36-1a. With such a mechanism, energy loss in the water passage WN36-1a, which rapidly expands, can be suppressed, and the efficiency of the whole water passage WN36-1a system can be increased. In particular, the effect is great in a use situation where the instantaneous discharge water amount is small.

FIG. 124 shows a cleaning nozzle WN38 according to another embodiment, and FIG. 124 (a) shows a cleaning nozzle WN38.
124B is a perspective view from the side of FIG.
8 is a cross-sectional view of FIG. 8 from another direction.

The washing nozzle WN38 has two water passages. That is, the wash water is arranged in the flow passage WN38-1h in the order of the flow direction of the wash water, in order from the upstream in the flow direction of the wash water, and the flow control valve WN38-3b and the rotation protrusion WN38-1d.
Water is discharged from the water discharge hole WN38-1b. In addition, the different system water is supplied from the water pump WN3 in order from the upstream in the flow direction of the different system water.
8-2, the flow control valve WN38-3a and the rotary water discharge means WN38-4 are disposed in the water passage WN38-1a, and are discharged from the discharge port WN38-1e to the outside of the washing nozzle WN38. The rotation projecting portion WN38-1d is a rotating water passage WN.
38-12d and a water discharge hole WN38-1b.
Further, the rotary water discharge means WN38-4 is provided with an impeller WN38-
4A, an impeller casing WN38-4b, an impeller bearing WN38-4c, and a seal portion WN38-4d. In addition, the rotation protrusion WN38-1d and the cleaning nozzle WN
38, a sealing portion WN38-1d is provided between the rotating projection portion WN38-1d and the rotating water discharging means WN38-4.
Prevent leakage of cleaning water from other than b. However, the seal portion W
The presence / absence of N38-4d and the sealing portion WN38-1f and the sealing property may be determined according to the use condition of the cleaning nozzle. In addition, the rotating protrusion WN38-1d and the impeller WN38
-4a is integrally formed via a shaft WN38-1g. The outlet WN38-31a of the flow rate control valve WN38-3a and the impeller WN38-4a are adjacent to each other. -4
a. The water pump WN38-2 and the flow control valve WN38-3a are provided with a control unit (not shown).
The flow control valve WN38-3b
Is also controlled by the control unit.

If the cleaning water and the separate system water are discharged in the configuration shown in FIG. 124, the separate system water is pressurized by the water pump WN38-2, and the movement required to rotate or substantially rotate the cleaning water. Energy is given, and is adjusted to a predetermined instantaneous discharge water amount by the flow control valve WN38-3a,
Flow into the impeller WN38-4a, a part of the kinetic energy is transmitted to the impeller WN38-4a, and the impeller WN38-4
While rotating a, it is discharged to the outside of the cleaning nozzle WN38 from the discharge port WN38-1e. Impeller WN38-4a
And the water discharge hole WN38-1b are integrally formed,
If the impeller WN38-4a rotates, the water discharge hole WN38-
1b also rotates, and the washing water is discharged while rotating or substantially rotating.

If the capacity of the water pump WN38-2 or the opening of the flow control valve WN38-3a is changed by the control unit, the instantaneous discharge amount of the different system water can be changed, and the kinetic energy of the different system water can be changed. Can be changed, the rotation speed of the impeller WN38-4a can be changed by changing the capacity of the water pump WN38-2 or the opening degree of the flow control valve WN38-3a.

Further, if the capacity of the water pump WN38-2 is changed by the control unit and the flow control valve WN38-3a is controlled by the control unit so as to maintain a predetermined instantaneous discharge water amount,
Although the instantaneous discharge amount of the separate system water is constant, the kinetic energy of the outflow from the outlet WN38-31a of the wash water can be changed, and thus the rotation speed of the impeller can be changed without changing the instantaneous discharge amount. . In this case, the water discharge hole WN38
If -1b is formed obliquely so as to incline outward with respect to the axis shown by the alternate long and short dash line, even the one shown in FIG. In addition, the pump control device functions as “fluctuation inducing means”.

Therefore, the instantaneous discharge amount of the separate system water is simply determined by controlling the capacity of the water pump WN38-2 or controlling the flow control valve W
Since it can be easily changed only by controlling the opening degree of N38-3a,
In a use environment where there is no limitation on the amount of water used in the separate system water, the rotation speed of the washing water can be changed easily or substantially without changing the instantaneous discharge amount of the washing water.

[0455] The discharged system water may be used separately, or may be discharged to the sanitary ware bowl when used as a local washing nozzle. The water pump WN38-2 is
Provided before distributing the wash water and the separate system water, the distribution ratio is adjusted by the flow control valve WN38-3a and the flow control valve WN38-3b, and the kinetic energy of the separate system water is supplied to the rotary spouting means W
N38-4, or depending on the object to be cleaned, the water pump WN38-2 may be used only for separate system water, or the water pump WN38- may be used for cleaning water and separate system water, respectively.
2 may be used.

[0456] In the above reference example, the number of holes of the water discharge hole was described as one. However, the number of holes of the water discharge hole does not hinder the embodiment of the present invention. The number may be determined by the designer.

In the above reference example, the use of a water pump has been described. However, in the case where tap water pressure is directly used or the case where a storage tank is provided and the head of the storage tank can be used, the present invention is sufficient. If a high water pressure and / or instantaneous discharge water volume can be obtained, a kinetic energy of flowing water can be adjusted by providing a pressure control valve instead of a water pump.
The kinetic energy of the flowing water can be controlled in the same manner as when the control is performed using a water pump, and the above reference example can be implemented by using a pressure control valve.

FIG. 126 shows a cleaning nozzle WN42 according to another reference example. FIG. 126 (a) is a sectional view, and FIG.
FIG. 126 (b) is a perspective view, FIG. 126 (c) is a layout diagram of the permanent magnet and the electromagnetic coil, and FIG. 126 (d) is a schematic diagram of the movement by the permanent magnet and the electromagnetic coil. Cleaning nozzle WN42
Has a water discharge hole WN42-4b that moves on a predetermined trajectory without rotating around the axis WN42-6a.

[0460] The cleaning nozzle WN42 is provided with a swing protrusion WN4.
2-44 is provided. The swing protrusions WN42-44 are
The water discharge hole WN42-4b, the moving water passage WN42-4a, and the permanent magnet WN42-53b are constituted by one body. The permanent magnets WN42-53b are arranged below the moving water passage WN42-4a in the axial direction of the shaft WN42-6a.
In the axial direction of the axis WN42-6a and the permanent magnet WN4
Below the 2-53b, the electromagnetic coil WN42-53a is disposed such that the magnetic pole generated by energization is directed to the axis WN42-6a. The swing protrusions WN42-44 are fixed by elastic flanges WN42-53c such that a gap WN42-53d is formed between the permanent magnet WN42-53b and the electromagnetic coil WN42-53a. Flange W
N42-53c is preferably made of a resin, but may be metal as long as it has a bellows structure. Electromagnetic coil W
Since N42-53a may be embedded in the main body of the cleaning nozzle WN42 due to its characteristics, the electromagnetic coil WN42-53a
a is embedded in the main body so that the electromagnetic coil WN42
-53a is not flooded. Mobile water channel WN42-
4a and the immovable water passage WN42-3a are connected by an elastic joint WN42-2. In addition, the spout hole WN42-
4b, moving water passage WN42-4a and permanent magnet WN42-
53b is a joint WN42-2 and a flange WN42-
The structure is movable in the radial direction with respect to the axis WN42-6a via the pin 53c.

The arrangement of the permanent magnets WN42-53b is shown in FIG.
As shown in FIG. 26 (c), four or more are arranged in a square or a rectangle, and each side is A, B, C, and D, respectively. The magnetic poles are arranged to be circumferentially alternating in a square or rectangular shape. The arrangement of the electromagnetic coils WN42-53a is shown in FIG.
As shown in FIG. 26 (c), four or more are arranged in a grid pattern, and the vertical and horizontal sides of the grid are (a1, a2,
...), (b1, b2, ...). Also, the permanent magnet WN
The relative arrangement of the electromagnetic coil WN42-53a and the electromagnetic coil WN42-53a is such that the side A of the permanent magnet WN42-53b and the side (a1, a2,. The (b1, b2, ...) sides of the coil are determined so as to be parallel or substantially parallel.

As shown in FIG. 126 (d), the magnetic poles are controlled by energizing the electromagnetic coils WN42-53a. For example, only the side A of the permanent magnet WN42-53b and the side a of the electromagnetic coil WN42-53a which is the closest are alternately arranged. Is supplied so that the magnetic pole becomes. As a result, the electromagnetic coil WN42-
53a, the permanent magnet WN42-53b
Between them, an attractive force or a repulsive force is generated, and the swing protrusions WN42-44 can be moved in the direction of the energized side.
Next, by energizing the side A of the permanent magnet WN42-53b and another side, for example, by energizing so that only the side b of the electromagnetic coil WN42-53a closest to the side B becomes an alternate magnetic pole,
The swing protrusions WN42-44 can be moved in the direction of the energized side. In this way, by repeating the energization for each side, the swing protrusion WN42-44 is
It can be swung around N42-6a.

Depending on the method of controlling the energization of the electromagnetic coils WN42-53a, for example, a1 side → b5 side → a5

It is also possible to rotate or substantially rotate N42-44. Further, the (a1, a2,...) Side and the (b1, b2,
...) The swing amplitude can be arbitrarily changed by selecting the side to be energized.

In the cleaning nozzle WN42 shown in FIG.
If the power supply to the electromagnetic coils WN42-53a is controlled and the cleaning water is discharged, the water discharge holes WN42-4b are moved to the shaft WN42-6.
Washing water is discharged while arbitrarily oscillating or rotating or substantially rotating without rotating around a. At this time, the spout hole WN42-4
The movement of b and the predetermined trajectory of the cleaning water after the water discharge is arbitrary swinging or rotating or substantially rotating. The cleaning nozzle WN42 according to this configuration can move the water discharging hole WN42-4b and the cleaning water after water discharging along a predetermined trajectory with a simple configuration without providing a seal portion. In this case, if the water discharge holes WN42-4b are formed obliquely so as to be inclined outward with respect to the axis WN42-6a shown in FIG.

44-73 is always inclined at a fixed angle by pressing the inner surface of the nozzle portion WN44-72. Also,
The nozzle portion WN44-72 has a straight line portion, and a part thereof is always connected to a hole communicating with the water discharge space WN44-71 and the water discharge hole WN44-75.

The flow of water inside the cleaning nozzle WN44 will be described in detail. When the user instructs washing, the flow regulating stepping motor WN of the flow regulating water stop valve WN44-42.
44-47 and the rotating ceramic disk WN44-46 connected thereto rotate. When the positions of the grooves provided in the rotating ceramic disks WN44-46 and the holes provided in the fixed ceramic disks WN44-45 overlap with each other, a water supply passage is formed and washing water starts flowing. FIG.
Reference numeral 8 denotes a rotating ceramic disk WN44-46 and a fixed ceramic disk WN44-
It is explanatory drawing which shows the shape of 45 grooves. As described above, since the water supply passage formed by the rotating ceramic disk WN44-46 and the fixed ceramic disk WN44-45 is formed so that the cross-sectional area changes depending on the rotational position, it is possible to control not only the water stoppage but also the flow rate. is there.

As described above, the flow regulating water stop valve WN44-42
Are installed near the water discharge holes WN44-75, and particularly, are installed inside the washing nozzle WN44, so that a flexible portion connecting a movable portion and a fixed portion when moving the washing nozzle WN44 back and forth before and after washing. Because there is no
Responsiveness of flow rate adjustment and water stoppage / water passage is extremely fast, and it can sufficiently follow the case where water stoppage / water passage is repeated at high speed or the flow rate is changed in a short cycle. In addition, reliable control is possible with less influence of the water supply pipe.

[0469] The check valve WN44-41 attached upstream of the flow regulating water valve WN44-42 is for preventing sewage from flowing backward from the water discharge hole. Since the check valve WN44-41 is attached near the water discharge hole WN44-75, the check valve WN44-41 is less affected by the water supply pipe and can be reliably controlled.

By operating the flow regulating water stop valve WN44-42,
When the water supply is started, the cleaning water is supplied to the check valve WN44-4.

Here, in accordance with the selection of the cleaning mode selected by the user, the control of the flow regulating water stop valve WN44-42 and the water discharge oscillating unit WN44-70 can be combined to perform the cleaning according to preference. That is, when the cleaning mode is selected, an electric signal is sent from the electric control device CT44-40, and the oscillating motor WN44-74 and the oscillating cam W connected thereto are transmitted.
N44-73 rotates. Swing cam WN44-73

It is determined by the inclination of the linear part immediately before 75, but since the inclination of this linear part changes over time by the swing cams WN44-73, the water discharge direction changes along a predetermined locus over time. In addition, since a part of the straight line portion immediately before the water discharge holes WN44-75 communicates with the water discharge portion space WN44-71, it is configured such that water can flow even when the nozzle portion WN44-72 is inclined at any angle. Have been.

As described above, since the water discharge rocking portion WN44-70 is installed immediately before the water discharge hole WN44-75, the movable portion for water discharge rocking is composed of very small parts. Therefore, the water discharge oscillating portions WN44-70 can be oscillated with a motor having a small torque, vibration and noise are small, and the reliability and reliability of the driving portion are greatly improved. In addition, high-speed swinging is possible, and the nozzle portion WN44-7 can be used.
The swing locus can be freely set by the shape of the inner surface of the second concave portion. Further, since the nozzle portions WN44-72 operate based on the electric signal, reliable and stepless control can be freely performed, and fast responsive control is also possible.

In the cleaning nozzle WN44, the oscillating motor WN44-74 is operated based on the electric signal. For example, an electric signal may be used as a trigger by using such a method.

It is possible to rotate or substantially rotate or swing without rotating around the axis WN46-6a. Further, since the angle で き る can be changed by controlling the energization of the electromagnetic coils WN46-52a, it is possible to discharge the washing water while rotating or substantially rotating or swinging at an arbitrary spread angle. Since the direction of the water discharge hole WN46-4b in the cleaning nozzle WN46 with respect to the axis WN46-6a can be arbitrarily changed, the water discharge trajectory rotates or substantially rotates or oscillates arbitrarily.

1b can be changed without changing the amount of current to each armature WN48-5a without changing the amount of current supplied to each armature WN48-5a. It is possible to move.

In this manner, the movement of the mover WN48-5b and the locus moving projection WN48-4 on the predetermined locus can be arbitrarily controlled. The area can be changed as desired, and in the case of washing a human body, various washing feelings in which the washing position and area change with time can be obtained.

When −41 d rotates counterclockwise, the water discharging section WN50-3 also rotates counterclockwise, so that the valve body WN50-32d is
It moves in the direction opposite to the rotation direction in N50-32c, and closes the water passage WN50-32e. As a result, the washing water passes only through the water passage WN50-32f, and the spout holes 50-31.
Water is discharged from only b while drawing a predetermined trajectory. Also,
When the rotation direction of the motor WN50-41d is clockwise,

FIG. 132 shows a cleaning nozzle WN52 according to another embodiment. FIG. 132 (a) is a sectional view, and FIG.
(B) is a perspective view of the main part. As shown in FIG. 132 (a), the ferromagnetic body WN52-51b, which is a component of the mover WN52-5b, has a locus moving protrusion WN52-4.
, A gap WN52-5c is provided below the ferromagnetic body WN52-51b, and a gap WN52-5 is further provided.
Armature WN52-5a is arranged below c. Ferromagnetic material W
The relative arrangement of N52-51b and armature WN52-5a is such that the ferromagnetic material WN52 is arranged as shown in FIG.
-51b and a plurality of armatures WN52-5a are circumferentially arranged at predetermined intervals, and each ferromagnetic material WN52-5-5
1b and armature WN52-5a are arranged so as to face each other. The direction of the magnetic pole of the armature WN52-5a generated by energization is set to face the opposite ferromagnetic material WN52-51b. The flange WN52-52b of the trajectory moving protrusion WN52-4 is instructed to have a conical clearance formed in the outer peripheral recess of the cleaning nozzle WN52. Movement element WN52-5b and locus moving projection WN5
2-4 is an elastic joint WN52-2 and a flange W
Through N52-52b, it is possible to move conically.

The material of the ferromagnetic material WN52-51b is a soft magnetic material (for example, Fe-Si [silicon steel], Fe-Ni [permalloy], Fe-Si-Al [Sendust], Mn-Zn ferrite, Crystalline alloy). In this case, in the cleaning nozzle WN52, any of the armatures WN
52-5a, the energized armature WN52
Attraction acts between −5a and the opposing ferromagnetic material WN52-51b, and the ferromagnetic material WN52-51b moves in the direction of the energized armature WN52-5a. Therefore,
Movable element WN52-5b and locus moving projection WN52-4
Tilts with respect to the non-energized state.

In this case, the order of energizing a plurality of armatures WN52-5a circumferentially arranged at a predetermined interval may be, for example, left or right without energizing two armatures WN52-5a at the same time. The energized armature WN52-5 is supplied by sequentially energizing clockwise or by energizing two adjacent armatures WN52-5a simultaneously and energizing counterclockwise or clockwise sequentially.
a and the attractive force acting between the ferromagnetic material WN52-51b sequentially moves left or right, so that the tilt of the mover WN52-5b also sequentially moves left or right, and the mover WN52-51b moves.
5b and the trajectory moving protrusion WN52-4 move in a conical shape without rotating left or right clockwise.

As the material of the ferromagnetic material WN52-51b, a hard magnetic material (for example, Fe-Ni-Co-Al [Alnico], Ba ferrite, rubber magnet, Sm-Co, Nd-Fe-B, etc.) may be used. it can. In this case, the ferromagnetic material WN52-51b
Armature WN52-5 with the N-pole or S-pole magnetic poles
a, the armature WN52-
If a current is applied so that the magnetic pole generated on the side of the opposite ferromagnetic material WN52-51b by 5a is opposite to the magnetic pole of the opposite ferromagnetic material WN52-51b, the same as in the case of using a soft magnetic material, , The opposing ferromagnet WN52-5
1b and the armature WN52-5a generate an attractive force, so that the ferromagnetic material WN52-51b is opposed to the energized armature WN5-5a.
It moves in the direction of 2-5a (the mover WN52-5b and the locus moving protrusion WN52-4 are inclined with respect to the non-energized state).

Therefore, the order of energizing the plurality of armatures WN52-5a circumferentially arranged at a predetermined interval is determined, for example, by turning left or right without energizing the two armatures WN52-5a at the same time. To each other, or two adjacent armatures WN
By simultaneously energizing 52-5a and sequentially energizing left or right, the attractive force acting between the energized armature WN52-5a and ferromagnetic material WN52-51b sequentially moves left or right, The tilt of the mover WN52-5b also sequentially moves left or right, and the mover WN52-5b and the locus moving projection WN52-4 move in a conical manner without rotating left or right clockwise.

Further, the energized armature WN52-a of the plurality of armatures WN52-5a circumferentially arranged at a predetermined interval.
5a and the armature WN52-5a on the opposite side of the circumference (hereinafter referred to as
In the embodiment, the two armatures WN52-5a are referred to as a pair armature WN52-5a), and a ferromagnetic material WN52-51b is used.
When a current is applied so that a repulsive force acts between the movable element WN5
The movement of the predetermined trajectory 2-5b can be performed more smoothly, which is suitable when a larger driving force is required. Further, the armature WN52-5a and the ferromagnetic material WN52
Armature WN5 without using the attractive force acting between
Even if the direction of energization to 2-5a is reversed to generate a repulsive force, and the repulsive force moves the predetermined trajectory, the same movement as that using the attractive force can be performed.

Therefore, when the cleaning water is discharged, the locus moving projection WN52-4 sequentially moves left or right in a conical shape, so that the cleaning water also moves while drawing a predetermined locus in a conical left or right direction. I do. Also, unlike the electric motor, no rotational force is generated in the circumferential direction, so that the locus moving protrusion WN52-4 does not rotate as in the case of driving the locus moving protrusion WN52-4 by the electric motor. , Joint WN
52-2 is a mover WN52-5b or a locus moving protrusion WN
There is no winding around 52-4 or malfunction.

Further, by changing the left or right turning energizing cycle, it is possible to change the moving speed of the predetermined trajectory of the mover WN52-5b, and thus the trajectory moving projection WN52.
The drive speed of the drive target such as -4 and wash water can be variably controlled. For example, when used as a wash nozzle for washing a human body, various washing feelings can be obtained according to the moving speed of the wash water.

Further, the energization order to the armature WN52-5a must be sequentially turned left or right (for example, the armature WN52-5a is moved back and forth by energization, and then is moved to another pair armature WN52-5a). When the armature WN52-5a is moved in another front-back direction by energizing the armature WN52-5a and the paired armatures WN52-5a to be energized are sequentially switched, or a plurality of armatures WN52-5a are simultaneously energized.
, And there are countless patterns, such as a case where a plurality of switches that are sequentially energized are sequentially switched.), The armature WN52-5a
Arbitrarily controlled predetermined trajectory in accordance with the power supply order to
The mover WN52-5b can be moved.

Further, if the armature WN52-5a is not arranged circumferentially but arranged in, for example, a U-shape or a polygon, the armature WN52-5b or the driven object can be arranged in the armature WN52-5a. It can be moved along any combined locus.

Further, by changing the amount of current supplied to the armature WN52-5a, the armature WN52-5a and the ferromagnetic material WN
The strength of the attractive force or the repulsive force acting between the movable element WN52-5b and the moving distance of the movable element WN52-5b can be changed. Therefore, the mover WN52-
5b moves in a predetermined locus in a conical shape, and the washing water is also discharged in a predetermined locus in a conical shape.
When the distance from the armature WN52-5a is large compared to the distance from the armature WN52-5a, the amount of current supplied to the armature WN52-5a is variably controlled, and the conical spread angle α of the armature WN52-5b is slightly reduced. , The spread of the washing water can be greatly changed, and the washing area can be largely changed by a slight difference in the moving distance of the mover WN52-5b.

Furthermore, some armatures WN52-5a are not arranged such that all the armatures WN52-5a face the direction of the opposing ferromagnetic material WN52-51b. For -5a, the magnetic poles are arranged in a direction deviating from the direction of the opposing ferromagnetic material WN52-51b, the sizes of the ferromagnetic materials WN52-51b are different from each other, or the armature and the opposing ferromagnetic material WN52-51b are different. If the gaps WN52-5c between the armature WN52-5a and the ferromagnetic material WN are different from each other,
The strength of the attractive force or the repulsive force generated between the armature WN52-5b and the armature WN52-5b can be changed without changing the amount of current supplied to each armature WN52-5a. It is possible to move a predetermined locus.

In this manner, the movement of the mover WN52-5b and the locus moving projection WN52-4 on the predetermined locus can be arbitrarily controlled. The area can be changed as desired, and in the case of washing a human body, various washing feelings in which the washing position and area change with time can be obtained.

FIG. 133 shows a cleaning nozzle WN54 according to another embodiment. FIG. 133 (a) is a sectional view, and FIG.

52, and is freely supported by the support portion WN54-52.
Relative to the water supply port WN54-2a. In addition, water inlet WN54-2a
Are separated from each other via a gap so that the discharged cleaning water is directed into the water inlet WN54-4a. Further, the armature WN54-6b can be incorporated in the cleaning nozzle WN54 so as not to be wet. In this case, the packing WN54-10 may not be provided.

In the structure shown in FIG. 133, the ferromagnetic material WN54-6 is used.
a is a soft magnetic material (for example, Fe-Si [silicon steel], Fe-Ni [permalloy], Fe-Si-Al
[Sendust], Mn-Zn ferrite, amorphous alloy, or the like), if any one of the armatures WN54-6b is energized, the ferromagnetic material WN54-6a opposed to the energized armature WN54-6b And the ferromagnetic material WN54-6a is opposed to the energized armature WN5
As the water moves in the direction of 4-6b, the water discharging section WN54-4
Tilt (deflect) with respect to the non-energized state. Therefore, a plurality of armatures WN54-6b circumferentially arranged at predetermined intervals.
The order of energization of the two armatures WN54
The current-carrying armature can be obtained by energizing the armature WN54-6b successively to the left or clockwise by simultaneously energizing the two armatures WN54-6b adjacently without energizing the motor −6b. Since the attractive force between the WN 54-6b and the ferromagnetic material WN 54-6a sequentially moves left or right, the inclination (deflection) of the water discharger WN 54-4 also sequentially turns left or right. The water discharging unit WN54-4 moves left or right without rotating.

In the configuration shown in FIG. 133, the ferromagnetic material WN54-6 is used.
a is a hard magnetic material (eg, Fe-Ni-Co-
Al [Alnico], Ba ferrite, rubber magnet, Sm-
Co, Nd—Fe—B), the ferromagnetic material W
The N54 or N pole of N54-6a is arranged so that the magnetic pole of the N or S pole faces the facing armature WN54-6b.
The magnetic pole generated on the a side is the opposite ferromagnetic material WN54-6.
When the current is supplied to the opposite pole to the magnetic pole of a, the opposite ferromagnetic material WN
Attraction works between 54-6a and armature WN54-6b,
The ferromagnetic material WN54-6a is connected to the opposed energized armature W
It moves in the direction of N54-6b. Therefore, the water discharge section WN5
4-4 tilts (deflects) with respect to the non-energized state.

Therefore, the order of energizing a plurality of armatures WN54-6b circumferentially arranged at a predetermined interval is determined, for example, by turning left or right without energizing the two armatures WN54-6b at the same time. To each other, or two adjacent armatures WN
By simultaneously energizing 54-6b and sequentially energizing left or clockwise, the attractive force acting between the energized armature WN54-6b and ferromagnetic material WN54-6a sequentially moves counterclockwise or clockwise. The inclination (deflection) of the water discharging section WN54-4 also sequentially turns left or right. In addition, the water discharging section WN54-4
Moves left or right without rotating.

Further, the energized armature WN54-b of the plurality of armatures WN54-6b circumferentially arranged at a predetermined interval.
6b and the armature WN54-6b on the opposite side of the circumference (hereinafter referred to as
If the two armatures WN54-6b are referred to as a paired armature in the embodiment so that a repulsive force acts between the two armatures WN54-6a and the ferromagnetic material WN54-6a, the predetermined locus of the water discharge portion WN54-4 moves. Can be performed more smoothly. Also,
Instead of utilizing the attractive force acting between the armature WN54-6b and the ferromagnetic material WN54-6a, the direction of energization to the armature WN54-6b is reversed to generate a repulsive force, and a predetermined locus is moved by the repulsive force. Even when the movement is performed, the same movement as in the case of using the attractive force can be performed.

In the structure shown in FIG. 133, if the actuator WN54-6 is driven in conjunction with the flushing of the washing water, the flushing section WN54-4 sequentially deflects clockwise or counterclockwise. Then, the washing water can be moved left or right in a predetermined locus. In addition, with only a slight deflection in the washing water spouting direction (actuator WN54-6).
A wide range of cleaning can be performed.

Also, by changing the left or right turning energization cycle, the moving speed of the predetermined trajectory of the water discharge section WN54-4 can be changed, so that the moving speed of the predetermined trajectory of the washing water can be controlled.

If the amount of current supplied to the armature WN54-6b is changed, the armature WN54-6b and the ferromagnetic material WN5
4-6a, the strength of the attractive force or the repulsive force can be changed, so that the moving distance of the water discharging unit WN54-4 can be changed, and the inclination (the amount of deflection) of the water discharging unit WN54-4 can be changed. Can be variably controlled by controlling the amount of current supplied to the armature WN54-6b, and thus the amount of deflection in the water discharge direction of the cleaning water can be controlled. be able to. further,
Since the cleaning area can be easily changed by only slightly changing the amount of deflection in the water discharge direction, it is only necessary to slightly change the amount of current supplied to the armature WN54-6b.

If the order of energizing the armature WN54-6b is not sequentially turned to the left or right (for example, the armature WN54-6b is moved back and forth by energizing it, and then another pair of armature WN54-6b For example, when the armature WN54-6b is moved in another front-rear direction by energizing to sequentially switch the armature WN54-6b to be energized, or when a plurality of armatures WN54-6b are energized at the same time and a plurality of armatures WN54-6b are simultaneously energized are sequentially switched. The water discharge section WN54-4 can be tilted (deflected) on an arbitrary controlled predetermined trajectory in accordance with the order of energizing the armature WN54-6b.
Various predetermined trajectories of the washing water can be moved. further,
If the armature WN54-6b is not arranged in a circumferential shape but arranged in, for example, a U-shape or a polygonal shape, the water discharge portion WN54-4 is inclined at an arbitrary locus corresponding to the arrangement of the armature WN54-6b (deflection). ), And the cleaning water can be moved along various predetermined trajectories.

[0503] Water inlet WN54-4a and water inlet WN54-
2a is isolated through a gap, and the water inlet WN is set so that the cleaning water discharged from the water supply port WN54-2a faces the inside of the water inlet WN54-4a during the operation of the water discharge section WN54-4.
By adopting the structure in which the water supply unit 54-4a is arranged, the water supply unit WN54-2 and the water discharge unit WN54-4 can be connected to each other in a non-contact manner.
Can draw an arbitrary movement trajectory within the movable range of, and in addition to the effect of the embodiment, it is possible to draw various water trajectories of washing water as described above with only a slight deflection of only the water discharging part WN54-4. Can be easily done. Therefore, the cleaning can be efficiently performed with the cleaning area corresponding to the portion to be cleaned, and the cleaning range can be changed at a high speed. Therefore, it is easy to efficiently perform the cleaning over a wide range. In particular, when used for human body washing, a wide washing feeling in a wide range of washing and a spot-like washing feeling in a narrow washing can be easily used without increasing or decreasing the flow rate of washing water. Can be easily handled. Therefore, as in the case where the cleaning area is made variable by increasing or decreasing the instantaneous discharge water amount, the temperature adjustment control of the heat exchanger that makes the cleaning water warm can not follow the increase or decrease in the instantaneous discharge water amount, and the cleaning area changes. Even when this is done, it is possible to discharge water at a stable hot water temperature.

In the cleaning nozzle WN54, the water inlet W
N54-4a and the water supply port WN54-2a are isolated via a gap, and the cleaning water discharged from the water supply port WN54-2a receives the water inlet WN5 during the operation of the water discharge section WN54-4.
By adopting a structure in which the water inlet WN54-4a is arranged so as to face the inside of 4-4a, it is possible to mix bubbles in the washing water by using an ejector effect or an air pump. Further, in the configuration of the embodiment, the actuator WN54-6 includes the water discharge section WN54-4 and the water supply section WN
It is also possible to form an integral structure with the device 54-2. For this reason, both the bubble mixing means and the actuator WN54-6 can be simultaneously and integrally configured in the water discharge section WN54-4 and the water supply section WN54-2, so that a more compact and highly reliable cleaning nozzle can be realized. Becomes The actuator WN54-6 can be applied to the cleaning nozzle shown in the embodiment.

It should be noted that, of the pair of opposing ferromagnetic materials WN54-6a and armature WN54-6b, one or more pairs of ferromagnetic materials WN54-6a and armatures WN54-6b are formed into an elastic spring structure. However, the ferromagnetic material WN54-6
The cleaning water can be moved along a predetermined trajectory by using the attraction and / or repulsion acting between the armature a and the armature WN54-6b.

In the scanning operation of the water inlet WN54-4a by the relative displacement operation of the water discharge section WN54-4,
The scanning area that is always secured is at least the water inlet WN
In addition to the area occupied by the cleaning water discharged from the water supply port WN 54-2a in the water supply port WN 54-4a,
The water inlet WN54-4a moves around the vicinity of the water inlet 54-4a, so that the scanning range of the water inlet WN54-4a and the shape of the opening of the water inlet are substantially the same. Therefore, water inlet WN5
The cleaning water discharged from 4-2a is surely supplied to the water inlet WN54.
-4a, the washing water does not leak to the other
N54-4b, water can be discharged from the water supply hole W. In addition to securing a stable flow rate of cleaning water and discharging water, all the cleaning water discharged from the water supply port can be used for cleaning.
The water discharge state of the cleaning water discharged from N54-4b can always be kept stable even if the water discharge unit WN54-4 moves.

Further, in the cleaning nozzle WN54, the water outlet WN54-2a and the water inlet WN5-4b move by a predetermined trajectory without rotating.
The installation direction of 4-4a is not restricted, and the water supply port W
N54-2a and the discharge direction of the wash water and the water discharge hole WN5.
The discharge direction of the cleaning water from 4-4b can be freely set.

In the cleaning nozzle WN54, one water inlet WN54-4a is connected to a plurality of water discharge holes WN54.
-4b, and a plurality of water inlets WN54-4a and water outlets WN54-4b can be provided in one water outlet WN54-4. It is also possible to have the same number or more of water supply ports WN54-2a corresponding to the water ports WN54-4a.

Also, with the configuration of the cleaning nozzle WN54, the amount of air mixed into the cleaning water can be changed.

FIG. 134 shows a cleaning nozzle WN56 according to another embodiment. FIG. 134 (a) is a sectional view, and FIG.
(B) is a drive switching mechanism diagram depending on the rotation direction of the electric motor WN56-4c. The cleaning nozzle WN56 has a configuration in which the cleaning water moves along a predetermined trajectory around the axis of the axis WN56-7.

As shown in FIG. 134 (a), the coupling WN56-A is connected to the rotating shaft WN56-41c of the electric motor WN56-4c, and the coupling WN5
The 6-A projection WN56-A1 is coupled to the coupling WN5.
6-B protrudes to the long groove WN56-B1. The coupling WN56-A has a structure that can slide in the long groove WN56-B1 using the long groove WN56-B1 as a guide. Further, the coupling WN56-B and the eccentric cam WN5
6-4d are connected, for example, as shown in FIG. 134 (b), the rotation of the electric motor WN56-4c in the left direction causes the protrusion WN56-A1 to reach the end WN56-B2 of the long groove WN56-B1. As it moves, coupling W
N56-B and the eccentric cam WN56-4d move upward in the drawing and rotate. Further, the electric motor WN56-4c
Is rotated rightward, the protrusion WN56-A1 moves to the end WN56-B3 of the long groove WN56-B1, so that the coupling WN56-B and the eccentric cam WN56-4.
d moves downward in the drawing and rotates.

[0512] The movable part WN56-4e is connected to the moving water passage WN.
56-3c, water discharge hole WN56-3d, and flange WN
The movable water passage WN56-3c and the immovable water passage WN56-3e have an elastic joint WN56-3.
f. An elastic packing WN56-3h is sandwiched between the flange WN56-41e and the flange receiver WN56-3g of the main body of the cleaning nozzle WN56. Therefore, the movable part W is moved so that the water discharge direction can be deflected three-dimensionally.
N56-4e is movable. Electric motor WN56-
4c does not receive the water pressure, so if it has a simple waterproof property, it does not have the packing WN56-3h, and the flange receiver WN56-3g and the flange WN56-41e can change the water discharge direction three-dimensionally. A predetermined clearance may be provided between them. In addition, the instantaneous discharge water volume adjustment of the wash water,
Performed by a flow control valve WN56-3b (not shown),
It is controlled by the control unit. Also, the electric motor WN56-4c
Is controlled by a control unit (not shown).

The eccentric cam WN56-4d and the eccentric cam receiver WN56-42e are in contact with each other, and the electric motor WN56-4c of the eccentric cam WN56-4d at the contact portion.
Moving part WN56-4e according to the amount of eccentricity of the
Deflects. As the eccentric cam WN56-4d rotates, the contact portion also sequentially moves clockwise or clockwise, so that the movable portion WN56-4e does not rotate according to the amount of eccentricity of the eccentric cam WN56-4d at the contact portion. The light is sequentially deflected three-dimensionally left or right.

In the configuration of FIG. 134, if the electric motor WN56-4c is driven in conjunction with the discharge of the cleaning water,
Since N56-4e sequentially deflects three-dimensionally to the left or right, the water discharge direction of the cleaning water is also three-dimensionally deflected, and the cleaning water is supplied to the cleaning nozzle WN56 with respect to the axis WN56-7 in the cleaning nozzle WN56. , Left or right in a predetermined locus. In addition, the three-dimensional slight deflection of the washing water spouting direction (the electric motor WN56-4)
Although the driving load of c is small), a wide range of cleaning can be performed.

Thus, in the embodiment, the electric motor W
N56-4c, the coupling WN56-A, the coupling WN56-B, and the eccentric cam WN56-4d are in the water discharge direction 3
The controller has a function as a dimensional deflection unit, and the control unit has a function as an independent control unit.

[0516] Further, by changing the rotation speed of the electric motor WN56-4c, the moving speed of the predetermined locus of the movable portion WN56-4e can be changed, so that the moving speed of the predetermined locus of the washing water can be controlled.

Further, by switching the direction of rotation of the electric motor WN56-4c clockwise or counterclockwise, the amount of eccentricity at the contact portion between the eccentric cam WN56-4d and the eccentric cam receiver WN56-42e can be changed. The size (deflection amount) of the three-dimensional inclination of the WN56-4e can be variably controlled by controlling the rotation direction of the electric motor WN56-4c, and thus the three-dimensional deflection amount of the washing water spouting direction can be controlled. Therefore, switching between cleaning of a wide range and cleaning of a narrow range can be performed only by changing the rotation direction of the electric motor WN56-4c. Further, since the cleaning area can be easily changed only by slightly changing the deflection amount in the water discharge direction three-dimensionally, it is not necessary to increase the size of the eccentric cam WN56-4d and the eccentric cam receiver WN56-42e. Therefore, in the embodiment, the electric motor WN
56-4c, the coupling WN56-A, the coupling WN56-B, and the eccentric cam WN56-4d have a function as a cleaning area changing unit.

FIG. 135 shows a cleaning nozzle WN58 according to another embodiment. FIG. 135 (a) is a sectional view, and FIG.
FIG. 13B is a cross-sectional view taken along the line AA in FIG.
FIG. 5C is a top view near the elastic body WN58-4 provided near the movable portion WN58-2.

[0519] The cleaning nozzle WN58 is provided with moving means WN58.
-3 and a movable portion WN58-2. The moving means WN58-3 is attached to a rotating shaft of the electric motor WN58-3c and the electric motor WN58-3c.
Eccentric cam WN58- eccentric from the rotation shaft of N58-3c
3D, and an annular follower WN58-3e separately contacting the eccentric cam WN58-3d. Annular follower WN58-
3e is also a component of the movable part WN58-2.

[0520] The movable portion WN58-2 is an elastic body WN58-.
4 is supported by the main body of the cleaning nozzle WN58.
The elastic body WN58-4 has a semi-ring-shaped portion WN58-41b.
And a spring-shaped resin WN58-4 having flange portions WN58-42b at both ends of a semi-ring-shaped portion WN58-41b.
b and sheet-shaped rubber WN58-4c, and the movable portion WN58-2 is supported by the flange portion WN58-42b with respect to the main body of the cleaning nozzle WN58. Flange W
N58-42b may be formed integrally with the movable portion WN58-2 and the main body of the cleaning nozzle WN58, or may be bonded or welded. Sheet shape rubber WN58-4
c is welded to the movable portion WN58-2 and the main body of the cleaning nozzle WN58 so as to spatially disconnect the inside and the outside of the cleaning nozzle. Therefore, the spring-shaped resin WN58-4b and the sheet-shaped rubber WN58-4c may be formed integrally or may be separated. In addition, the spring-shaped resin WN58-4b can further improve the durability when the fixing position of the cleaning nozzle WN58 to the main body is determined in accordance with the distribution of the load applied to the elastic body WN58-4.

[0521] By the rotation of the electric motor WN58-3c,
The eccentric cam WN58-3d is connected to the annular follower WN58-3e and the movable portion WN58-2 in contact with each other in accordance with the eccentricity ratio.
Is moved without rotating in one direction continuously,
The washing water spouted from the spout hole WN58-2b on the movable part WN58-2 can be swung. Further, since the water discharge hole WN58-2b is supported by the spring-shaped resin WN58-4b, the cleaning water is conically discharged in a movement range smaller than the movement of the annular follower WN58-3e. Further, since the cleaning water is discharged while entraining air from the ejector port WN58-2c, it is possible to improve water-saving cleaning and detergency due to the incorporation of air, and to improve the feeling of cleaning in the case of human body cleaning.

[0522] The sheet-shaped rubber WN58-4c is
The sheet-shaped rubber WN58-4c can be integrated with the movable portion WN58-2 and the cleaning nozzle WN58 body by screwing, bonding, or insert molding. Furthermore, sheet-shaped rubber WN58-4c
Instead of rubber, the main body of the cleaning nozzle WN58 and the movable portion WN58-2 may be formed in two colors by using an elastomer instead of rubber.

Therefore, the electric motor WN58-3c as the moving means WN58-3, the eccentric cam WN58-3d, the annular follower WN58-3e, and the spring-shaped resin WN58
-4b and the sheet-shaped rubber WN58-4c can stably discharge the conical water of the cleaning water, and use the electric motor WN53-3. Except for the effect of performing washing in a wide range to a wide range and the effect of making the swing locus (washing locus) variable, the same effects as those described in the embodiments can be easily and reliably implemented.

[0524] The spring-shaped resin WN58-4b may be made of metal. However, in this case, it is preferable to select a shape or a material (for example, stainless steel) resistant to rust or to perform a rust-prevention process, if necessary, in order to prevent rust and the like due to being wet.

[0525] The movable portion WN58-2 has a configuration in which water is discharged in a conical shape. However, the movable portion WN58-2 is a pendulum-shaped water discharge that deflects the wash water in only two directions, or an oscillating water discharge that does not deflect the water discharge direction of the wash water. You may.

FIG. 136 is an explanatory view showing a cleaning nozzle WN60 according to another embodiment. The cleaning nozzle WN60 is
A water supply system for supplying the cleaning water, and an air system for mixing the compressed air into the cleaning water and swinging the rotary rocking body WN60-26 are provided. The flow of the washing water is, in order from the upstream, a water pump WN60-11, a flow control valve WN60.
-12, water supply channel WN60-13, rotation swing means WN60
-14, through the water discharge passage WN60-25, the water discharge hole WN60-
Water is discharged from 15. The air flow path has two systems, and the first air flow is, in order from the upstream, the air pump AP60-16,
First air valve AP60-17a, first air flow path A
After passing through P60-18a, it enters the rotation oscillating means WN60-14, and transmits the kinetic energy of air to the air port AP60.
From -19, it is discharged outside the cleaning nozzle WN60. Also, the second air flow is based on the air pump AP60-16,
The second air valve AP60-17b passes through the second air flow path AP60-18b and passes through the air bubble mixing means AP60-20.
And mixed into the water in the water discharge channel WN60-25 and discharged together with the washing water. The rotation swing means WN60-14 is
Air turbine AP60-21 and eccentric cam WN60-
22, a bearing WN60-23, and a flexible joint WN60
-24, the rotary oscillator WN60-26, and the water discharge channel WN6.
0-25 and a spout hole WN60-15. Air turbine AP60-21 and eccentric cam WN60
-22 are integrally formed, and this is the bearing WN60.
Supported by -23. The air is in the first air flow path A
When the air flows into the air turbine AP60-21 through P60-18a, the air turbine AP60-21 and the eccentric cam WN60-22 rotate by the kinetic energy of the air. The eccentric cam WN60-22 causes the oscillating body WN60-26 to move along a predetermined trajectory in the horizontal direction by the eccentric portion. The locus is determined by the notch shape of the rotary oscillator WN60-26. Rotating rocker WN60-26 and water discharge channel W
N60-25 are integrally fixed, and these are fixed by a swing fixing portion WN60-29 at the tip of the water discharge passage WN60-25 so that they can swing in the horizontal direction around the rotary oscillator WN60-26. Has become. The tilt of the water discharge passage WN60-25 is changed by the swing, and the water discharge direction of the washing water is changed. Air bubble mixing means AP60-
20 is an air chamber AP60-27 and a water discharge channel WN60-25.
Is constituted by a porous body WN60-28 provided on the outer wall. When air flows into the air chamber AP60-27 through the second air flow path AP60-18b and the pressure rises, the air flows through the porous body WN60-28 and the water discharge passage WN60-27.
The washing water is mixed with the washing water in 25 and discharged together with the washing water.

In the cleaning nozzle WN60 of FIG.
If flush water is instructed, flush water is supplied to the water pump WN60.
At the same time as pressurization by -11, the flow control valve WN
The water amount is adjusted to a predetermined instantaneous discharge amount by 60-12, and water is discharged from the water discharge hole WN60-15 through the water supply passage WN60-13 and the water discharge passage WN60-25.

When the user instructs the rotation of the washing water, the air pump AP60-16 pressurizes the air,
Air valve AP60-17a is opened, and the air passes through the first air flow path AP60-18a, and the air turbine AP60
-21 and rotate it, and the eccentric cam WN60-
22, the water discharge passage WN via the rotary rocking body WN60-26.
The angle of 60-25 changes, and the washing water can be rotated or swung.

As described above, only the vicinity of the water discharge hole WN60-15 in the cleaning nozzle WN60 is rotated by using the kinetic energy of the air, so that the entire cleaning nozzle is moved along a predetermined locus to rotate or swing the cleaning water. As compared with the case where water is discharged, the moving part is small, and there is almost no electric drive noise or vibration by the actuator, and the sound is very excellent in quietness and non-vibration. Further, the rotation swing means WN60-
14, only the vicinity of the water discharge holes WN60-15 is rotated, so that it is easy to shorten the rotation or oscillation cycle of the washing water, and there is a water saving effect due to the effective dispersion of the washing water.

Also, since there is no direct electric drive part for rotating or swinging the washing water, a very compact washing nozzle can be provided. Further, the durability of the electrically driven portion does not matter.
Furthermore, unlike the case where electric power is transmitted by wiring, there is no leakage from the wiring due to the cleaning water, and the leakage does not pose a problem when used in an environment where the cleaning nozzle itself is apt to be wet. Furthermore, there is no need for electrical wiring work up to the nozzle tip.

[0531] If the user indicates that air bubbles are mixed, the second air valve AP60-17b is opened, and air flows into the air chamber AP60-27 through the second air flow path AP60-18b. When the pressure in the air chamber AP60-27 increases, the air passes through the porous body WN60-28 and mixes into the cleaning water as a number of fine bubbles. Since a large amount of fine air bubbles can be mixed into the washing water, the water splash is reduced, and the washing power is very excellent even with a small amount of water. .

[0532] Further, the rotation speed for rotating or oscillating the washing water, the instantaneous discharge water amount, and the amount of air bubbles can be independently controlled. The number can be variably controlled from low speed to high speed, and the amount of air bubbles can be controlled in a wide range, so cleaning for human body such as cleaning nozzle of local cleaning device, shower head for human body cleaning and faucet spout for hand washing. When used as a nozzle, it is possible to vary only the feeling of cleaning with a constant instantaneous discharge water amount, and, despite the constant instantaneous discharge water amount, can sufficiently cope with various users' washing preferences. Since the washing feeling can be varied without depending on the increase or decrease of the instantaneous water discharge amount, the temperature control of the heat exchanger that makes the washing water warm can not follow the increase or decrease of the instantaneous water discharge flow rate. Even when the variable can perform a stable hot water temperature water discharge.

Further, since an air pump for rotating or oscillating the water discharge direction of the washing water and an air pump for mixing air bubbles are used, a compact and inexpensive apparatus can be provided, and the oscillating and oscillating operation can be performed at high speed. It is possible to reduce the problem of flying splash, which is likely to occur at the time, by mixing bubbles, and to make the washing feeling soft.
Furthermore, if both are combined, drastic water saving cleaning becomes possible.

FIG. 137 is an explanatory view showing a cleaning nozzle WN61 according to another embodiment. The cleaning nozzle WN61 is
A configuration is used in which a part of the compressed air from the air supply means for oscillating the washing water rotation oscillating means WN61-14 is used for the bubble mixing means AP61-20 for mixing air into the washing water. That is, a part of the air that has exited from the rotation oscillating means WN61-14 is discharged to the outside of the washing nozzle WN61 from the air port AP61-19, while another part of the air passes through the air passage and is mixed with the bubble mixing means AP61. -20 and provided on the outer wall of the water discharge channel WN61-25.
It is mixed into the washing water through -28 and discharged together with the washing water. According to this configuration, it is not possible to independently control the air mixing and the rotation swing, but the cleaning nozzle WN
The air flow path in the nozzle 61 can be shared, the air bubbles can be mixed and the rotation oscillated at the same time with a small amount of air, and the air flow rate can be controlled independently of the discharge amount of the washing water.

FIG. 138 shows a cleaning nozzle WN62 according to another embodiment, in which FIG. 138 (a) is a diagram viewed from the side and FIG. 138 (b) is an explanatory diagram viewed from above. The cleaning nozzle WN62 is provided with a rotation swinging means WN62-14 for swinging the water discharge holes WN62-15 by compressed air. The flow of the washing water is, in order from the upstream, the water pump WN62-1.

The water is discharged from the water discharge hole WN62-15 through the nozzle 25. The air flow path is, as shown in FIG.
After passing through the passage 62-16, it is divided into two paths, respectively, through the air valve AP62-17 and the air passage AP62-18, and enters the rotary swing means WN62-14 to transmit the kinetic energy of the air to the cleaning nozzle. It is discharged outside WN62. The rotation swing means WN62-14 is provided with an air nozzle AP6.
2-30, a flexible joint WN62-24, a rotary rocker WN62-26, a spring WN62-31, a water discharge passage WN62-25, and a water discharge hole WN62-15. The rotary rocking body WN62-26 has a water discharge passage WN.

The rotary oscillator W discharged from the air nozzle AP62-30 and held by the spring WN62-31
N62-26 is swung alternately from two directions. By this swing, the direction of water discharge can be changed by changing the inclination of the water discharge passage WN62-25 connected to the rotary rocking body WN62-26. Here, if the switching cycle of the air valve AP62-17 is shortened, it is possible to rotate or swing water at a short cycle.
Is increased, the inclination of the water discharge passage WN62-25 changes greatly, and the water discharge direction and the water discharge area can be largely changed.

According to the structure of the cleaning nozzle WN62,
Since the area (spread) of the spouted water and the cycle of rotation or oscillation can be controlled independently of the flow rate, the cleaning nozzle WN62 can support various types of cleaning modes.
In addition, the washing nozzle WN62 can rotate or swing at high speed even with a small amount of air, so that the user can obtain a feeling of washing as if water is being spouted from the entire water spouting surface, and can greatly save water. It is.

Also, by inverting the direction of current supply to the electromagnetic coil WN66-54a, the generated magnetic pole can be reversed. Without using the water outlet hole WN66-4b on the shaft WN66-6.
It can be moved in a reciprocating motion repeatedly back and forth across a.

In the cleaning nozzle WN66, when the power supply to the electromagnetic coils WN66-54a is controlled and the cleaning water is discharged, the water discharging hole WN66-4b is moved to the axis WN66-6a.
, The washing water is spouted back and forth (while drawing a predetermined trajectory).

[0546] As the elastic joint WN66-2 in the cleaning nozzle WN66, it is preferable to use a resin tube, but a metal may be used as long as it has a bellows structure.

The ferromagnetic material W used for the cleaning nozzle WN66
As a material of N66-54b, a hard magnetic material generally used for motors (for example, Fe-Ni-Co-A
l [Alnico], Ba ferrite, rubber magnet, Sm-C
o, Nd-Fe-B, etc.) and soft magnetic materials (for example, F
e-Si [silicon steel], Fe-Ni [permalloy], F
e-Si-Al [Sendust], Mn-Zn ferrite, amorphous alloy, etc.) can be considered.
The present invention can be implemented as long as it is a ferromagnetic material that generates an attractive force or a repulsive force by the magnetic field of 6-54a.

FIG. 141 shows a cleaning nozzle WN68 according to another embodiment, and FIG. 141 (a) is a sectional view of FIG.
(B) is an oblique perspective view. The cleaning nozzle WN68 deflects the cleaning water in a two-dimensional manner to move the cleaning water along a predetermined trajectory to discharge water while swinging the water discharge swinging part WN6.
8-8.

As shown in FIG. 141 (a), the water discharge oscillating portion WN68-8 includes a mover WN68-8a and two armatures WN68-8b, and the mover WN68-8.
a has two ferromagnetic bodies WN68-81a, a moving water passage WN68-3c, a water discharge hole WN68-3d, and a flange WN68-82a. Two armatures WN68-
8b is a movable element WN68 sandwiching the movable element WN68-8a.
-8a, two ferromagnetic bodies WN6
8-81a is arranged so as to face each armature WN68-8b. An air gap WN68-8c is provided between the ferromagnetic material WN68-81a and the armature WN68-8b. The moving water passage WN68-3c is an immovable water passage WN68.
-3e via an elastic joint WN68-3f. An elastic packing WN68-3h is interposed between the flange WN68-82a and the flange receiver WN68-3g. Therefore, the mover WN6
8-8a is movable so that the water discharge direction can be deflected two-dimensionally. Further, the armature WN68-8b can be incorporated in the main body of the cleaning nozzle WN68 so as not to be wet. In this case, the water discharge direction can be changed two-dimensionally without using the packing WN68-3h. As described above, a predetermined clearance may be provided between the flange receiver WN68-3g and the flange WN68-82a. In addition, the instantaneous discharge water amount adjustment of the wash water is performed by the flow control valve WN68-3.
b (not shown), and is controlled by a control unit (not shown). Further, the driving of the water discharge rocking unit WN68-8 is controlled by the control unit.

In the configuration of the cleaning nozzle WN68 in FIG. 141, the material of the ferromagnetic material WN68-81a is a soft magnetic material (for example, Fe—Si [silicon steel], Fe—Ni [permalloy], Fe—Si—Al [Sendust] and Mn-
(Zn ferrite, amorphous alloy, etc.), if any one of the armatures WN68-8b is energized, the ferromagnetic material WN68-
81a and the ferromagnetic material WN68-81a
Moves in the direction of the opposing energized armature WN68-8b. Therefore, the mover WN68-8a tilts (deflects) with respect to the non-energized state.

Therefore, by alternately energizing the two armatures WN68-8b in order of energization, the attractive force acting between the energized armature WN68-8b and the ferromagnetic material WN68-81a generates an attractive force acting on the mover WN68. -8a works alternately before and after or left and right, so the tilt (deflection) of the mover WN68-8a
Are also changed two-dimensionally alternately.

The material of the ferromagnetic material WN68-81a is a hard magnetic material (eg, Fe—Ni—Co—Al [Alnico], Ba ferrite, rubber magnet, Sm—Co, N
d-Fe-B), the ferromagnetic material WN68-
The armature WN6 to which the N-pole or S-pole of 81a is opposed
Armature WN arranged to face 8-8b and energized
The magnetic pole generated on the side of the opposing ferromagnetic substance WN68-81a by the ferromagnetic substance WN68-81a
When the current is supplied so as to be opposite to the magnetic pole of the ferromagnetic material WN6, as in the case where the soft magnetic material is used,
Attraction works between 8-81a and armature WN68-8b,
The ferromagnetic material WN68-81a moves in the direction of the opposing energized armature WN68-8b. Therefore, the mover WN
68-8a inclines (deflects) with respect to the non-energized state.

Further, the ferromagnetic material WN68-81 is connected to the energized armature WN68-8b and another armature WN68-8b.
a, the movable element WN
The movement of the predetermined locus of 68-8a can be performed more smoothly. In addition, without using the attractive force acting between the armature WN68-8b and the ferromagnetic material WN68-81a, the direction of current supply to the armature WN68-8b is reversed to generate a repulsive force, and the repulsive force causes a predetermined locus to be formed. Even if the movement is performed, it is possible to perform the same movement as in the case where the attractive force is used.

[0555] If the water discharge swinging unit WN68-8 is driven in conjunction with the discharge of the cleaning water, the movable element WN68-8a is two-dimensionally deflected. Deflects the cleaning water to the cleaning nozzle WN68 with respect to the axis WN.
It can be moved by reciprocating reciprocation (predetermined trajectory) back and forth or left and right across 68-7. In addition, a wide range of washing can be performed with only a two-dimensional slight deflection in the washing water spouting direction (even though the driving load of the spout swinging unit WN68-8 is small).

As described above, in the cleaning nozzle WN68, the water discharge oscillating portion WN68-8 has a function as a two-dimensional deflecting device in the water discharging direction, and the control portion has a function as an independent control device.

If the energization cycle is changed, the mover W
Since the moving speed of the predetermined locus of N68-8a can be changed, the moving speed of the predetermined locus of the washing water can be controlled.

Thus, as in the case of a washing nozzle that performs two-dimensional deflection in the water discharge direction using a fluid element mechanism, the moving speed (oscillation frequency) of a predetermined trajectory increases or decreases according to an increase or decrease in the instantaneous discharge water amount. It is possible to easily control the moving speed (oscillation frequency) of a predetermined trajectory independently of the increase and decrease of the instantaneous discharge water amount, and it is necessary to change the cleaning flow rate as in the case of using a fluid element mechanism. Instead, cleaning can be performed at a moving speed that matches the surface to be cleaned.

Further, when the feeling of washing is a problem in washing the human body, only the feeling of washing can be made variable while the instantaneous discharge water amount is constant. In addition to being able to sufficiently respond to the taste of the user, the washing feeling can be varied without depending on the increase or decrease of the instantaneous discharge water amount. The temperature control of the heat exchanger does not fail to follow the increase or decrease in the instantaneous water discharge flow rate, and the stable hot water discharge can be performed even when the washing feeling is made variable.

Further, since the cleaning nozzle WN68 itself is not driven and the driving portion is smaller than in the conventional case in which the cleaning water spouting direction is two-dimensionally deflected by an actuator disposed outside the cleaning nozzle, a predetermined trajectory of the cleaning water is obtained. Providing a compact cleaning nozzle and cleaning device that can easily increase the moving speed of the cleaning, change from low speed to high speed, start up at high speed at once, and increase the responsiveness of switching the cleaning area. can do. Also, in the case of washing the human body, various washing feelings can be easily obtained as compared with the conventional case in which the washing water spouting direction is two-dimensionally deflected by an actuator provided outside the washing nozzle.

If the amount of current to the armature WN68-8b is changed, the armature WN68-8b and the ferromagnetic material WN6
Since the strength of the attractive force or the repulsive force acting between the mover WN68-8a and the mover WN68-8a can be changed, the magnitude of the two-dimensional inclination of the mover WN68-8a can be changed. Since the (deflection amount) can be variably controlled by controlling the amount of current supplied to the armature WN68-8b, and thus the two-dimensional deflection amount in the water discharge direction of the washing water can be controlled,
Switching between cleaning in a wide range and cleaning in a narrow range can be easily performed. Furthermore, since the cleaning area can be easily changed only by slightly changing the amount of deflection in the water discharge direction two-dimensionally, it is only necessary to slightly change the amount of current supplied to the armature WN68-8b. Therefore, in the embodiment, the water discharge swinging unit W
N68-8 has a function as a cleaning area changing unit.

Therefore, switching between cleaning in a wide range and cleaning in a narrow range can be achieved by only slightly changing the amount of deflection in the water discharge direction (only by changing the amount of power to the armature WN68-8b). Good), as in the case of the cleaning nozzle using the fluid element mechanism, there is no problem that the amplitude (cleaning area) of the predetermined trajectory increases or decreases according to the increase or decrease of the instantaneous discharge water amount.
The responsiveness of switching the cleaning range can be easily performed at a high speed regardless of the increase or decrease of the instantaneous discharge water amount, and the cleaning can be performed with the cleaning area corresponding to the surface to be cleaned regardless of the increase or decrease of the instantaneous discharge water amount.

Further, when the cleaning nozzle is held by hand for cleaning the human body, the cleaning area can be changed without greatly moving the hand, and when the cleaning nozzle is fixed, the cleaning area can be reduced without moving the human body or a part of the human body. Because it can be changed, even in the case where the movement of the body is inconvenient, even for elderly people and children, it is possible to variably wash a wide range and a narrow range without inconvenience.

Further, in the case of human body washing, a wide washing feeling in a wide range of washing and a spot-like washing feeling in a narrow washing can be easily used independently of the increase or decrease of the instantaneous discharge water amount, and further various washing feelings can be obtained. It can be easily handled.

[0564] Further, in the case of washing the human body, the temperature control of the heat exchanger that makes the washing water warm can not follow the increase or decrease of the instantaneous ejection water amount, as in the case where the washing area is made variable by increasing or decreasing the instantaneous ejection water amount. In other words, even when the cleaning area is made variable, it is possible to discharge water at a stable hot water temperature.

[0565] The cleaning nozzle WN68 can be configured such that one of the two sets of opposing ferromagnetic materials WN68-81a and armature WN68-8b has a stretchable spring structure. Utilizing the attraction and / or repulsion acting between the armatures WN68-8b, the cleaning water is moved relative to the cleaning nozzle WN68 in a reciprocating reciprocating motion (predetermined locus) back and forth or right and left across the axis WN68-7. be able to.

FIG. 142 is a perspective view showing a cleaning nozzle WN70 and a cleaning nozzle WN72 according to another reference example. The cleaning nozzle WN70 shown in FIG. 142 (a) includes a nozzle rotation motor WN70-41b on the side opposite to the water discharge hole, and the nozzle rotation motor WN70-41b
A structure for swinging the water discharge hole WN70-1 is provided. The cleaning nozzle WN72 shown in FIG. 142 (b) includes two nozzle front / rear drive motors WN72-41c and nozzle left / right drive motors WN72-41d. Then, the water discharge hole WN72-1 is moved to a predetermined locus.

FIG. 143 is an explanatory view showing a cleaning nozzle WN74 according to another reference example. The cleaning nozzle WN74 is
The fluid device WN74-1 is provided. This fluid element WN
74-1 oscillates the cleaning water discharged from the water discharge hole WN74-2 according to the flow velocity.

FIG. 144 is an explanatory view showing a cleaning nozzle WN76 according to another reference example. The cleaning nozzle WN76 is
The nozzle rotation motor WN76-41b moves the nozzle itself left and right, and the fluid element WN76-1 swings the cleaning water back and forth. The fluid element WN76-1 is
The cleaning water discharged from the water discharge hole WN76-2 is swung according to the flow velocity. According to the cleaning nozzle WN76, water can be discharged three-dimensionally from the water discharge hole WN76-2.

FIG. 145 is an explanatory view showing a cleaning nozzle WN77 according to another reference example. The cleaning nozzle WN77 is
A vibration motor 41e for vibrating the water discharge hole is provided, and the vibration of the vibration motor 41e is propagated to oscillate the cleaning water. Such a water discharging means by the vibration motor 41e may be combined with a configuration in which the nozzle itself moves. Further, a configuration in which these trajectory control units are combined may be employed.

FIG. 146 shows a cleaning nozzle WN78 according to another embodiment, and FIG. 146 (a) is a schematic structural view,
6B is an explanatory diagram illustrating a state in which the water discharge direction is deflected right and left, and FIG. 146C is an explanatory diagram illustrating a state in which the water discharge direction is deflected forward and backward. Cleaning nozzle WN78
Is provided with a configuration for three-dimensionally deflecting the water discharge direction of the cleaning water.

The front-rear deflection motor WN78-4a is fixed to a cleaning nozzle support (not shown), and its rotating shaft WN78-41a is connected to a nozzle guide WN78-21b. In addition, the left and right deflection motor WN78-4b
Is fixed to a nozzle guide WN78-21b, and its rotating shaft WN78-41b is connected to the cleaning nozzle WN78. The rotation axis direction of the front-rear deflection motor WN78-4a is different from the rotation axis direction of the left-right deflection motor WN78-4b. Also, the cleaning nozzle W
N78 is supported by the nozzle guide WN78-21b so as to rotate in the left-right direction. The cleaning nozzle WN78 is controlled by the control unit CT78-5. That is, the control unit CT78-5 controls the instantaneous discharge water amount of the washing water by the flow control valve WN78-3b, and controls the driving of the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b.

[0572] Therefore, if the control section CT78-5 discharges the washing water while switching and controlling the rotation direction of the left and right deflection motor WN78-4b, the control section CT78-5 changes the discharging direction of the washing water as shown in FIG. 146 (b). It can be deflected two-dimensionally. The control unit CT78-5 includes a front-rear deflection motor WN.
If the cleaning water is spouted while switching and controlling the rotation direction of 78-4a, the spouting direction of the cleaning water can be deflected two-dimensionally in the forward and backward directions as shown in FIG. 146 (c).

In the cleaning nozzle WN78, if the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b are driven in conjunction with the discharge of the cleaning water, the front-rear two-dimensional deflection and the left-right two-dimensional deflection in the water discharge direction can be achieved. By combining the deflection, the water discharge direction of the cleaning water can be deflected three-dimensionally, and the cleaning water is discharged while moving along a predetermined trajectory. In addition, by the combination of the reversal frequency and the rotation angle by the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b, the water discharge direction is not only sequentially deflected cyclically,
Various predetermined trajectories of the washing water can be moved. Thus, the front-rear deflection motor WN78-4a and the left-right deflection motor W
N78-4b has a function as a three-dimensional deflecting unit in the water discharge direction, and the control unit CT78-5 has a function as an independent control unit.

Therefore, despite the small driving load of the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b, it is possible to discharge water over a wide area by three-dimensional slight deflection in the direction of water discharge. it can.

Even when the reversing frequency of the front / rear deflection motor WN78-4a and the left / right deflection motor WN78-4b is driven at a high frequency, since the driving load is small, vibration and noise generated by the driving can be reduced. Further, a front-rear deflection motor WN78-4a and a left-right deflection motor WN78
-4b makes it easy to increase the moving speed of a predetermined trajectory of the washing water, change it from a low speed to a high speed, or start it up to a high speed at once, regardless of the instantaneous discharge water amount. The cleaning can be performed at a moving speed suitable for the surface to be cleaned without depending on the cleaning speed. Besides, in the case of human washing,
Moving the washing water at a high speed gives a continuous and soft feeling of washing, while moving the washing water at a low speed gives a strong washing feeling with intermittent stimulation. Can be varied, and it is possible to easily cope with various tastes of washing feeling. Also, in the case of human body washing, as in the case where the feeling of washing is made variable by increasing or decreasing the instantaneous water discharge amount, the temperature control of the heat exchanger that makes the wash water hot can not follow the increase or decrease of the instantaneous water discharge flow rate. In addition, even when the washing feeling is made variable, it is possible to discharge water at a stable hot water temperature.

Also, by performing a drive for slightly changing the rotation angle of the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b, it is possible to switch between a wide range of cleaning and a narrow range of cleaning. The switching of the range can be easily performed at high speed without depending on the increase or decrease of the instantaneous discharge water amount, and the cleaning can be performed with the cleaning area corresponding to the surface to be cleaned, regardless of the increase or decrease of the instantaneous discharge water amount. Therefore, in the cleaning nozzle WN78, the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b have a function as a cleaning area changing unit.

Further, when the washing nozzle WN78 is held by hand for washing the human body, the washing area can be changed without greatly moving the hand. Because the area can be changed, even in the case where the movement of the body is inconvenient, or even for the elderly or children, it is possible to vary the washing of a wide area and a narrow area without inconvenience.

[0578] In the case of human body washing, a wide washing feeling in a wide range of washing and a spot-like washing feeling in a narrow washing can be easily used irrespective of the increase or decrease of the instantaneous discharge water amount. It can be easily handled.

In the case of washing the human body, the temperature control of the heat exchanger that makes the washing water hot can not follow the increase or decrease of the instantaneous discharge water, as in the case where the washing area is made variable by increasing or decreasing the instantaneous discharge water amount. In other words, even when the cleaning area is made variable, it is possible to discharge water at a stable hot water temperature.

[0580] Further, when the deflection in the water discharge direction is sequentially and cyclically repeated by the combination of the reversal frequency and the rotation angle by the front-rear deflection motor WN78-4a and the left-right deflection motor WN78-4b, a wide range of cleaning is required. The cleaning can be smoothly changed to the range of cleaning, and the cleaning object adhered to the surface to be cleaned can be cleaned so as to be sequentially collected at the center of the circular cleaning. Therefore, not only does the cleaning object adhering to the surface to be cleaned not be unnecessarily spread, but also the cleaning efficiency can be increased by collecting the cleaning object in one place.

FIG. 147 is an explanatory view for explaining a local cleaning apparatus provided with a cleaning nozzle WN80 according to another reference example. The cleaning nozzle WN80 includes an intermittent discharge unit WN80-4.
It has. The washing nozzle WN80 includes a water supply means WN80-1, a heat exchanger TH80-2, and a hot water storage section TH.
Wash water is supplied via 80-5. Water supply means WN8
0-1 is a water pump WN80-13, a water stop valve WN80-
14 and a flow control valve WN80-15. Wash water from the water supply means WN80-1 is supplied to the heat exchanger T
H80-2 is supplied to the hot water storage section TH80-5. The intermittent discharge means WN80-4 includes an electromagnetic valve WN80-43. The electromagnetic valves WN80-43 turn on and off the water passage at a predetermined intermittent frequency. This electromagnetic valve WN
By turning on / off by 80-43, the discharge of the washing water becomes intermittent as shown in FIG.
As shown in (b), the pulsation occurs. Since the electromagnetic valve WN80-43 can change its on / off time from a low speed to a high speed, the intermittent frequency can be easily changed from a high value to a low value. Intermittent discharge means WN8
The position where 0-4 is arranged is best immediately before the water discharge holes WN80-42, because the followability of intermittent discharge is better downstream of the water passage. Further, since the hot water storage portion TH80-5 is provided between the heat exchanger TH80-2 and the intermittent discharge means WN80-4, it is possible to reduce a temporal variation of the washing water passing through the heat exchanger TH80-2. Because it is possible, heat exchanger TH80-
2 facilitates temperature control of the washing water. In the case of intermittent discharge in which the discharge of the wash water is performed intermittently, the control of the instantaneous discharge water amount, the flow rate of the wash water, and the space volume ratio of the wash water is performed by the water pump WN80-13 or the flow control valve WN80-.
15 and by controlling the electromagnetic valves WN80-43 for controlling the cleaning water discharge time in a temporal intermittent cycle or one intermittent cycle. The water pump WN80-13 and the flow control valve WN80-15 are controlled by the control unit.

With the cleaning nozzle WN80, even if the flow rate of the cleaning water is increased, the instantaneous discharge water amount can be further reduced (further water saving) according to the cleaning water discharge time or the cleaning water discharge amount in one intermittent cycle. Since the washing water flow rate can be increased, the washing power can be secured, and even though the washing water flow rate has been increased, the instantaneous discharge water amount can be further reduced. A feeling of washing can be secured. Furthermore, since the local area in the local area is not continuously washed, the washing water is intermittently applied when viewed from the local area in the local area, and the feeling of cleaning is improved by the intermittent stimulation. That is,
Water can be further conserved while maintaining sufficient cleaning power and comfortable cleaning feeling.

Also, the frequency of the intermittent stimulus can be changed by changing the intermittent frequency of the wash water. Therefore, by controlling the intermittent frequency of the wash water, the wash water can be intermittently viewed from a local local range. Can be controlled. For example, I do not like intermittent stimulation,
If you prefer a continuous feeling of cleaning, use the electromagnetic valve WN80-4.
By controlling the on / off of 3 at a high speed, the intermittent frequency of the cleaning water can be controlled at a high speed, and the user can obtain a more continuous cleaning feeling. In particular, if the cleaning water is discharged at the frequency of the intermittent stimulus that is equal to or higher than the threshold at which the local part senses the intermittent stimulus, the effect of the continuous stimulus feeling is remarkable. Conversely, when strong intermittent stimulation is desired, the user can obtain strong intermittent stimulation by controlling the on / off of the electromagnetic valves WN80-43 to be driven at a low speed. Further, by controlling the intermittent frequency of the washing water to change with time, it is possible to sufficiently cope with the user's various washing feeling preferences.

FIG. 148 is an explanatory diagram for explaining a local cleaning apparatus provided with a cleaning nozzle WN84 according to another reference example. The cleaning nozzle WN84 has a shower discharge configuration for discharging cleaning water from a water discharge hole WN84-42 having a plurality of discharge holes. In the case of shower discharge in which washing water is discharged from the water discharge holes WN84-42 having a plurality of water discharge holes WN84-42, the control of the instantaneous discharge water amount, the flow rate of the cleaning water, the volume ratio of the cleaning water space, and the cleaning area is performed by a water pump. WN84-
13 or by controlling the flow control valve WN84-15 and the variable valve WN84-45. The water pump WN84-13 and the flow rate control valve WN84-15 are provided with the cleaning water supply control means CT84-71 of the controller CT84-7.
Is controlled by

FIG. 149 is a sectional view showing a cleaning nozzle WN86 according to another reference example. The cleaning nozzle WN86 is
Flow control water stop valve WN86-42 for temporally controlling water discharge
And an intermittent water discharge unit WN86-76 for controlling the ON-OFF time of water discharge. The intermittent water discharge unit WN86-76 is a minute valve body WN86 having a permanent magnet WN86-77a attached to the head disposed at the tip of the nozzle body.
-77, an ultra-small electromagnetic coil WN86-78 made by a semiconductor fine processing technology for sucking it, and a valve element WN8
Spring body WN86-7 for pressing 6-77 against the nozzle body
9. When the user instructs washing, the flow regulating water stop valve WN86-42 is operated to start spouting of washing water. At the same time, depending on the cleaning mode selected by the user, the electromagnetic coil WN of the intermittent water discharge unit WN86-76 is used.
When a magnetic force is generated by flowing a current through the valve 86-78, the valve body W
N86-77 is attracted and opened by magnetic force against the force of the spring body WN86-79, and the washing water flows out of the gap. By passing an alternating current through the electromagnetic coil WN86-78 in a short cycle, the direction of the magnetic force can be changed, and the opening and closing operation can be repeated by pressing or pulling the valve element WN86-77. In this manner, the valve body W immediately before the water discharge hole WN86-75 is used.
Since the N86-77 is opened and closed, there is no deterioration in responsiveness due to minute air present in the water supply pipe or expansion of the pipe, and intermittent water discharge in a short cycle or short-time water discharge is possible. . Furthermore, since the minute valve body WN86-77 operates based on an electric signal, reliable and stepless control can be freely performed, and control with high responsiveness is also possible.

FIG. 150 is an explanatory view showing a cleaning nozzle WN89 according to another reference example. In the cleaning nozzle WN89, a water pump may be used to supply cleaning water to the rotating disk WN89-42c. As the water pump, in the case of a positive displacement pump, the flushing cycle, the intermittent cycle in terms of stroke, or the flush water discharge time in one intermittent cycle may be controlled. The rotating disk WN89-42
When an intermittent variable valve is used instead of c, a plunger-type on-off valve may be used. In this case, if the water discharge holes WN89-42d are formed obliquely so as to incline outward with respect to the rotation axis of the motor, even if the water discharge holes are shown in FIG. ), And the motor control device is a "fluctuation inducing means"

FIG. 151 is an explanatory view for explaining a local cleaning apparatus provided with a cleaning nozzle WN90 according to another reference example. In the washing nozzle WN90, when the washing water is supplied from the washing water supply means WP90-1, the washing water flows into the washing nozzle WN90 via the heat exchanger TH90-2 which makes the washing water warm, and is discharged from the water discharge holes WN90-31. Local cleaning is performed. The cleaning water supply unit WP90-1 performs the cleaning water discharge on-off.
And a water force changing means WP90-12 for adjusting the flow rate of the washing water and changing the water force.

The washing water discharging means WP90-11 is provided with a valve section WP90-11a comprising an opening / closing valve, a check valve and the like.
And a water pump WP90-11b mounted when water pressure is insufficient or when water pressure is not used. The configuration of the valve unit WP90-11a changes depending on the required quality and the supply form of cleaning water (supply using water pressure, supply from a storage tank, etc.). For example, in the case of supply using water pressure, the valve unit WP90-11a May have a pressure reducing valve.

[0589] The water force changing means WP90-12 is composed of a flow control valve WP90-12a, a water pump WP90-12b, etc., and has an air pump (not shown) for discharging cleaning water mixed with air. Water pump WP

[0590] The control unit CT90-6 is provided with a washing water discharge control means CT90-61 for controlling the discharge of the washing water, a water force change control means CT90-63 for controlling the water force of the washing water, and an electric power to the heat exchanger TH90-2. It has heat exchanger control means CT90-62 for controlling the supply. User operation section S
Local cleaning operation instructing means SW by operation of W90-7 or the like
90-71 are operated, and the local cleaning operation instruction means SW90 is operated.
A signal for instructing discharge of the wash water from -71 is transmitted to the wash water discharge control means CT90-61, and the wash water discharge control means CT90-61 outputs the wash water discharge means WP90-11.
And the cleaning water is discharged. Further, the user operates the operation unit SW90-7 to operate the water pressure indicating means SW90-.
72 is operated, and a signal for instructing the water level of the washing water from the water level instructing means SW90-72 is supplied to the water level change control means CT90.
-63, the water force change control means CT90-63 controls the water force change means WP90-12 to change the water force of the washing water. The water pressure instructing means SW90-72 may indicate the water force by turning a knob from the high side setting to the low side setting, or may indicate the water force by pressing a strong button or a weak button.

In the case where the cleaning water is intermittently discharged,
It is possible to achieve the same discharge power E as before while increasing the flow rate v of the cleaning water and reducing the instantaneous discharge water amount Q without reducing the cleaning area. Therefore, the instantaneous discharge water amount Q at the time of the strongest water force is set to 6.7 × 10 ⁻⁶ [m ³ / sec] or less, and the conventional water force has the same discharge force E as the setting of the strongest water force. While ensuring the same detergency as the setting of the strongest water force, a hard washing feeling can be enjoyed, and the instantaneous discharge water amount Q at the time of the weakest water force is 0.67 × 10 ⁻⁶ [m ³ / sec.
c] above, the conventional water force has the same discharge force E as the weakest water force setting, so that the conventional water force has the same detergency as the weakest water force setting while removing dirt and the like adhering to the local part. There is no trouble that it does not run down, and you can enjoy a soft cleaning feeling. In this way, if the design is made to increase or decrease the discharge force E equivalent to the conventional one, it is possible to change the water force to correspond to the user's various preferences similar to the conventional one despite the fact that the instantaneous discharge water amount is reduced, It can be carried out easily and reliably without reducing the cleaning power.

Even if the instruction of the water force is set to the weakest water force, if the design is made so that the discharge force E satisfies 0.03 [W] or more, the cleaning can be performed with the same cleaning power as the conventional one. In addition, since the cleaning power is reduced, there is no problem in that, for the same cleaning time as in the related art, contaminants remain in a local area or the cleaning time is longer than in the conventional case.

Also, assuming that the above-mentioned embodiment is for general household use (AC 100 V), the allowable current value of one power supply is about 15 A, and the lower limit value of the variation of the power supply voltage is about 85 V AC. About 1275 with power supply
Since W is an allowable value, if it is designed so that the instantaneous discharge water amount Q at the time of the strongest water pressure satisfies 6 × 10 ⁻⁶ [m ³ / sec] or less, an instantaneous heat exchanger without fear of running out of hot water. When using, it can be used simultaneously with other devices while exhibiting a sufficient temperature-raising performance of about 40 ° C even in the middle of winter. For example, the power consumption of the heater for the toilet indoor heating device can be set to 200 [W].

Further, all the above-mentioned embodiments or modifications,
As for the reference example, the instantaneous discharge water amount Q at the time of the strongest water force is 4.8.
If it is designed to satisfy × 10 ^-6 [m ³ / sec] or less, when using an instantaneous heat exchanger that does not have to worry about running out of hot water, it will exhibit a sufficient temperature rise performance of about 40 ° C even in midwinter. In addition, it can be used simultaneously with more or more devices that use a large amount of power. For example, the power consumption of the heater for the toilet room heating device can be 400 [W].

As described above, by paying attention to the discharge force E, if the design is made to increase or decrease the discharge force E equivalent to the conventional one,
When it is desired to perform water-saving cleaning, it is possible to easily and surely (without trial and error) changing the water force corresponding to various user preferences similar to the conventional one without reducing the cleaning power.

FIG. 152 is an explanatory view showing a cleaning nozzle WN91 according to another reference example. This cleaning nozzle WN91
Is a reference example having a rotary discharge mechanism as a discharge unit so that the cleaning water draws a predetermined trajectory. Wash water rotation motor WN
91-41a near the tip of the nozzle, and by rotating the washing water rotation motor WN91-41a, the water discharge hole W
N91-31 rotates, and the cleaning water is discharged while drawing a predetermined trajectory. In this case, if the water discharge holes WN91-31 are formed obliquely so as to incline outward with respect to the rotation axis of the motor, even if the water discharge holes are shown in FIG. ”, And the motor control device functions as“ fluctuation inducing means ”.

12a, the discharge force E = ρ × Q × v
× v [W] can be increased or decreased, and if the design is made such that the discharge force E is increased or decreased as in the conventional case, it is possible to easily carry out the water pressure change corresponding to the user's various preferences as in the conventional case. .

If the effective area of the water discharge holes of the water discharge holes WN91-31 is reduced, it is possible to achieve the same discharge force E as before while increasing the washing water flow rate v and reducing the instantaneous discharge water amount Q. Therefore, the instantaneous discharge water amount Q at the time of the strongest water force is 6.7 × 1
0 ^-6 [m ³ / sec] or less, and the conventional water force has the same discharge force E as that of the strongest water force setting. And the instantaneous discharge amount Q at the time of the weakest water force is set to 0.67 × 10 ⁻⁶ [m ³ / sec] or more, and the discharge force E of the conventional water force is equivalent to the setting of the weakest water force. By doing so, it is possible to enjoy a soft washing feeling without the problem that the dirt and the like adhering to the local part does not flow down while the same detergency as the setting of the weakest water force is obtained with the conventional water force. In this way, if the design is made to increase or decrease the discharge force E equivalent to the conventional one, it is possible to change the water force to correspond to the user's various preferences similar to the conventional one despite the fact that the instantaneous discharge water amount is reduced, It can be carried out easily and reliably without reducing the cleaning power.

Further, since the washing water draws a predetermined trajectory, the washing area can be made equal to the conventional one, so that not only a problem such as a large movement of the body (buttock) does not occur, but also a local As can be seen, the washing water is intermittent and does not stimulate continuously, so that the intermittent stimulation further enhances the washing feeling.

By stopping the current supply to the armatures 102-84a, the attractive force between the armature WN102-84a and the ferromagnetic material WN102-83a is released, and the armatures WN102-84a are displaced by the reverse movement of the plunger WN102-82a due to the tension of the spring WN102-85a. The water channel is closed, and the discharge of the cleaning water is turned off. Also, based on the settings of the water pressure setting dial SW102-13d and the discharge temperature setting dial SW102-13e, the electromagnetic valve WN is transmitted by a signal via the hot water / nozzle control device.
102-81a and the flow control unit WP102-35 are controlled. In addition, the control of the intermittent rate of the cleaning water and the control of the intermittent frequency are performed by turning on and off the power supply to the electromagnetic valves WN102-81a. Further, the instantaneous discharge water amount used in the following description does not indicate a minute variation in the instantaneous discharge water amount due to intermittent discharge, but indicates an average instantaneous discharge water amount when the intermittent ratio and the discharge flow rate are not changed. Also,
In the present invention, the intermittent rate is calculated as “((OFF time of discharge of cleaning water) / (O of discharge of cleaning water) during one intermittent cycle).
N time + OFF time of discharge of cleaning water).

Here, for example, if the user sets the water pressure setting dial SW102-13d to “strong” water pressure, the electromagnetic valve WN102-81a and the flow control unit WP102-3 are set.
As a result of the intermittent discharge of the washing water under the control of 5, the discharge flow rate becomes 1
0 [m / sec], instantaneous discharge water amount is 430 [cc / mi]
n], and the cleaning water is discharged. Despite the instantaneous discharge water amount of 430 [cc / min], the discharge flow rate is 10 [m / sec]. Therefore, even a user who wants to obtain a strong water force should simulate and secure a sufficient water force. And the instantaneous discharge water amount is 430 [cc / mi
n], even a user who wants to wash at a high temperature (for example, 40 ° C. or more) can perform washing at a favorite hot water temperature even in the middle of winter, and furthermore, consumption in the washing water heating means TH102 while maintaining a washing feeling. The power can be limited to 1200 [W] or less. Further, if the intermittent ratio of the discharged washing water is further increased and the discharge flow rate is increased, the instantaneous discharged water amount can be reduced while maintaining the washing power and the feeling of washing, and the power consumption of the washing water heating means TH102 is further limited to a small value. it can.

[0613] Also, the user sets the water pressure setting dial SW10.
If 2-13d is set to "weak" water force, the electromagnetic valve WN
Under the control of the flow control unit 102-81a and the flow control unit WP102-35, the instantaneous discharge water amount is the same as the "strong" water force, and only the intermittent ratio of the discharged wash water can be made small or zero, and the discharge flow rate becomes 2 [ m / sec], and the instantaneous discharge water amount is adjusted to be 430 [cc / min], and the wash water is discharged. Since the discharge flow velocity is 2 [m / sec], even a user who wants to obtain a weak water force can perform mild washing without pain, and the instantaneous discharge water amount is 430 [cc / min] despite the weak water force. So
It is possible to provide a high-quality local cleaning device in which the width of the power supply control for temperature adjustment in the cleaning water heating means TH102 can be widened, and the accuracy with respect to the target hot water temperature can be easily ensured.
Further, the washing water heating means TH102 while maintaining the washing feeling.
Can be limited to 1200 [W] or less.

[0614] Instead of changing the instantaneous discharge water amount, the electromagnetic valve WN102-81a and the flow control unit WP102-
By the control of 35, at the time of the "weak" water force, the instantaneous discharge water amount is also controlled to be reduced, so that the user is quasi-satisfied so that the desired water force is obtained. Can be limited to

Also, a combination of a water force change by changing the discharge ratio and the discharge flow rate without changing the instantaneous discharge water amount and a water force change by changing the instantaneous discharge water amount simulate the user to obtain a desired water force. May be satisfied. In this case, for example, when the setting by the water pressure setting dial SW102-13d is "strong" water force to "slightly strong" water force, the instantaneous discharge water amount is set to 430 [cc / min], and the water force is changed by increasing or decreasing the discharge ratio and the discharge flow rate. , Water force setting dial SW102-
When the setting by 13d is "slightly strong" to "slightly weak", the instantaneous discharge water amount is set to 380 [cc / min], the water pressure is changed by increasing / decreasing the discharge ratio and the discharge flow rate, and the water pressure setting dial SW102-13d. Is slightly weak
When the water force is "weak", the instantaneous water discharge amount is 330 [cc
/ Min] to change the water force by increasing or decreasing the discharge rate and discharge flow rate.

Also, in the reference example of FIG. 158, the description has been given of the reference example in which the discharge of the cleaning water is intermittently controlled by the electromagnetic valve WN102-81a. Since it can be satisfied, the disc valve having a predetermined opening is rotated using a motor, and the discharge of the cleaning water is turned on and off, for example, by turning on and off the discharge of the cleaning water.
What is necessary is just to be able to control -OFF.

FIG. 159 is an explanatory view showing a local cleaning apparatus provided with a cleaning nozzle WN104 according to another reference example.
159 (a) is a sectional view of the nozzle body WN104-50 and the nozzle head WN104-70, a block diagram of a water flow system and a control instruction system, and FIG. 159 (b) is a discharge section WN104-82e and a discharge hole group disk. WN104
-81e as viewed from the discharge direction. Here, the power limiting unit CT104-8 includes a discharge hole group WN104-8e, which is an aggregate of a plurality of discharge holes, and a cleaning water flow rate control unit CT104-8b. Discharge hole group WN

The discharge hole group disk WN104-81e has a discharge hole group unit W having a total water discharge hole area of 7.2 × 10 −7 [m 2].
N104-83e, water discharge hole total area is 9.6 × 10-7
[M2] discharge hole group unit WN104-84e,
It has a discharge hole group unit WN104-85e having a water discharge hole total area of 3.6 × 10 −6 [m 2], and a switching motor WN
104-86e and ejection hole group disk WN104-81e
Is rotated by a predetermined angle (in this reference example, 15 [deg]), the cleaning water is discharged from the discharge hole group unit communicating with the discharge hole group WN104-8e on the discharge unit WN104-82e. Cleaning water flow rate control unit CT104-8b
Comprises a flow control unit WP104-35. Further, based on the settings of the water force setting dial SW104-13d and the water discharge temperature setting dial SW104-13e, the switching motor WN104- is controlled by a signal via the hot water / nozzle control device.
86e and the flow control unit WP104-35 are controlled.

Here, for example, if the user sets the water force setting dial SW104-13d to "strong" water force, the switching motor WN104-86e selects the discharge hole group unit WN104-85e as a water discharge hole, and the flow control unit W
In P104-35, the cleaning flow rate is adjusted to 10 [m / sec] and the instantaneous discharge water amount is adjusted to 430 [cc / min], and the cleaning water is discharged. Instantaneous discharge water amount is 430 [cc
/ Min], the discharge flow rate is 10 [m
/ Sec], a user who wants to obtain a strong water force can simulate and secure a sufficient water force, and the instantaneous discharge water amount is 430 [cc / min]. [° C. or more], a user who wishes to perform cleaning can also perform cleaning at the desired hot water temperature even in the middle of winter, thereby limiting the power consumption in the cleaning water heating means TH104-31 to 1200 [W] or less while maintaining a feeling of cleaning. can do. In addition, since the ejection hole group is disposed so as to be sufficiently dispersed so as to be able to clean the same cleaning area as in the related art, there is no problem that the cleaning area is reduced. Further, if the total area of the water discharge holes of the discharge hole group unit is further reduced, the discharge flow velocity of the wash water is greatly increased, and the wash water can be sufficiently dispersed within the wash area by increasing the number of holes. The power consumption of the water heating means TH104-31 can be limited to a smaller value.

[0619] Also, the user sets the water pressure setting dial SW10.
If 4-13d is set to “weak” water force, the switching motor WN
The discharge hole group unit W is used as a water discharge hole by 104-86e.
N104-83e is selected and the flow control unit WP104
At -35, the discharge flow rate is adjusted to 2 [m / sec], and the instantaneous discharge water amount is adjusted to 430 [cc / min], and the wash water is discharged. Since the discharge flow velocity is 2 [m / sec], even a user who wants to obtain a weak water force can perform mild washing without pain, and the instantaneous discharge water amount is 430 [cc / min] despite the weak water force. So
The width of power supply control for temperature adjustment in the washing water heating means TH104-31 can be widened, it is easy to ensure the accuracy with respect to the target hot water temperature, and it is possible to provide a high-quality local washing device, and thus maintain a feeling of washing. Washing water heating means TH
The power consumption in 104-31 can be limited to 1200 [W] or less.

In the reference example, the use of the discharge hole group units has been described separately. However, only the discharge hole group units WN104-85e are used, and at the time of “weak” water pressure, control is also performed to reduce the instantaneous discharge water amount so that the desired water force is obtained. The user may be satisfied in a pseudo manner. In this case, precision is required for the energization control in the washing water heating means, but the switching motor WN104-86 is required.
e is not required and the number of parts can be reduced, so that not only the cost can be reduced but also the size can be reduced, and the power consumption in the washing water heating means TH104-31 can be reduced while maintaining the washing feeling.
00 [W] or less.

Also, the user may be satisfactorily satisfied with a desired water force by a combination of a water force change by properly using the discharge hole group unit and a water force change by changing the instantaneous discharge water amount. In this case, for example, the power setting dial SW1
When the setting by 04-13d is "strong" to "somewhat strong", the combination of the discharge hole group disk WN104-85e and the increase / decrease of the instantaneous discharge water amount is performed, and the water setting dial SW1 is used.
The setting by 04-13d is "somewhat strong" water force ~ "somewhat weak"
At the time of the water pressure, the combination of the discharge hole group unit WN104-84e and the increase / decrease of the instantaneous discharge water amount is performed.
Setting by W104-13d is "slightly weak" water force-"weak"
In the case of a water force, the present invention can be implemented by performing the discharge hole group unit WN104-83e in combination with the increase and decrease of the instantaneous discharge water amount.

[0622] Even if both the buttocks cleaning and the bidet cleaning are performed by a single discharge mechanism, and if they are performed by different nozzles, the practice of the present invention is not hampered, and the above embodiments are combined with the respective discharge modes. Thus, it is possible to satisfactorily satisfy the user with the water pressure set by the water pressure setting dial SW104-13d with a smaller amount of instantaneous discharge water.
4-13d, while the user is quasi-satisfied so as to have the water force set by the cleaning water heating means TH104-
The power consumption of the power supply 31 can be limited to 1200 [W] or less, and can be further reduced to a lower power consumption.

In the above embodiment, the buttocks washing setting means SW104-13a or the bidet washing button SW1 is used.
Although the current is controlled based on the operation of 04-13b, the instantaneous cleaning water heating means TH104-31 for heating the supplied cleaning water to the target temperature instantaneously has been described, but the supplied cleaning water is temporarily stored. Water temperature setting dial SW104
A hot water storage type washing water heating means for constantly heating and keeping the temperature at the appropriate temperature set at -13e may be used. In this case, the amount of instantaneous discharge water can be reduced by half as compared with the conventional method, so that even when washing is performed for a long time, the hot water runs out. And the capacity of the washing water heating tank can be made smaller than before, so the heat radiation in the washing water heating tank is also small, and the transportability and workability of the local cleaning device can be improved significantly, resulting in a satisfactory usability. It is possible to provide a local cleaning device which achieves both convenience and energy saving.

At 0-82d, if air is mixed through the fine gaps of the porous body, air can be mixed as finer bubbles, and since the bubbles are fine, the loss of bubbles is small and the amount of mixed air is greatly increased. As a result, the discharge flow rate can be further increased to reduce the instantaneous discharge water amount, and furthermore, the power consumption of the washing water heating means TH130-31 can be limited to a small value, and a sufficient bubble state can be obtained even when colliding with a local part. Since it is maintained, there is no problem such as pain due to the air cushion effect even though the flow velocity is greatly increased.

The user sets the water pressure setting button SW130
If -13d is set to "weak" water force, the air pump AP1
By controlling the flow control unit 30-81d and the flow control unit WP130-35, the instantaneous discharge water amount is the same as the “strong” water force, and only the ratio of forced mixing of air into the wash water can be reduced or set to zero. 3 [m / sec] and the instantaneous discharge water amount is adjusted to be 430 [cc / min], and the wash water is discharged. Since the discharge flow velocity is 3 [m / sec], even a user who wants to obtain a weak water force can perform mild washing without pain, and the instantaneous discharge water amount is 430 [cc / min] despite the weak water force. So that
The width of the power supply control for temperature adjustment in the washing water heating means TH130-31 can be widened, the accuracy with respect to the target hot water temperature can be easily ensured, and a high-quality local washing device can be provided, and the feeling of washing can be maintained. Washing water heating means TH
The power consumption in 130-31 can be limited to 1200 [W] or less.

In the above reference example, the instantaneous discharge water amount is not changed, but the air pump AP130-8 is used.
