DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local human body cleaning apparatus for cleaning a local part of a person using a toilet bowl with water.

[0002]

2. Description of the Related Art An apparatus for cleaning a human body local part is configured to wash out dirt adhering to a local part of a human body by spraying cleaning water from a nozzle toward the local body part. In general,
In order to obtain high cleaning performance, it is preferable to apply water to the local part with as strong a water pressure as possible. However,
For washing delicate parts like a woman's vagina,
A water force having a softer feeling than other parts, for example, near the anus, is required. On the other hand, in the conventional human body local cleaning device described in JP-A-8-49279, while the nozzle moves between predetermined positions, the force of water spouting from the nozzle is changed with the movement. Has become. Specifically, in order to change the water level of the cleaning water according to the area to be cleaned, a concentrated cleaning jet that obtains a strong water pressure by intensively applying water to a relatively narrow area, and a water jet that spreads over a relatively wide area. A water discharge hole capable of forming a dispersed washing jet that obtains a soft water force by applying water thereto is prepared, and two types of water forces are switched by changing the water discharge hole to be used as the nozzle moves.

[0003] In addition to the above-described conventional apparatus, as for the ass washing, air (bubbles) is appropriately added to the washing water in order to provide a less irritating washing to a user suffering from hemorrhoids. Some of them realize a softer cleaning jet compared to normal cleaning by mixing them.

[0004]

By the way, all excretions from the human body, such as urine, menstrual blood, vaginal discharge (under the obi), etc., are liquid, but their physical properties, especially There is a great difference in viscosity, which greatly affects the cleaning performance with water. For example, urine and vaginal discharge during pregnancy have a very low viscosity, whereas vaginal discharge before and after the ovulation period generally have a high viscosity. Further, excretions are not necessarily discharged from the human body only when the toilet seat is seated, but vaginal discharge, menstrual blood, and the like are discharged from the human body regardless of time and place. These excreta are discharged from the vagina and then adhere to the surrounding skin, but during menstruation, menstrual blood spreads widely, oxidizes by contact with air, and becomes solidified on the skin surface There is also. Furthermore, the stool excreted from the anus has various states depending on the physical condition of the body and the like, and may be stuck to the skin surface around the anus.

As described above, there are various types and states of excrement to be removed by the human body cleaning device, and even if the type of excrement to be removed is the same, excrement attached to the local part is removed. Appropriate water force and washing range when washing are not constant. For this reason, at a water force or a cleaning position which is set in advance in a conventional human body local cleaning device as a standard, sufficient cleaning cannot always be performed, and unwashed portions may occur. Conventional human body cleaning devices are usually provided with a key switch that allows the user to adjust the water force and nozzle position, and it is possible to eliminate almost no washing residue by making appropriate adjustments. Such adjustments are rather cumbersome. Further, in general, when the user adjusts the water pressure and the nozzle position, it is often adjusted based on the personal preference of the feeling of washing, such as, for example, preferring a strong water pressure, wanting to use a weak water pressure for hemorrhoids and the like. ,
At present, it is not always adjusted with the intention of completely removing excrement.

The present invention has been made in view of the above points, and a main object of the present invention is to provide a reliable and high irrespective of the type and condition of excrement without performing complicated and troublesome operations and adjustments. It is an object of the present invention to provide a human body local cleaning device capable of exhibiting a cleaning ability.

[0007]

[0008] That is, a first human body local cleaning apparatus according to the present invention comprises: a) a nozzle for discharging cleaning water toward the user's human body local part; and b) a discharge of excrement from the user, which is an object to be cleaned. And a water discharge control means for determining a water discharge condition of the wash water from the nozzle according to physical properties.

Further, a second apparatus for cleaning a human body part according to the present invention comprises: a) a nozzle for discharging washing water toward a human body part of a user; and b) excrement from the user, which is an object to be cleaned. Water discharge control means for determining a water discharge condition of the wash water from the nozzle in accordance with a range of the adhered skin surface and / or a state of adhesion of the excrement.

There is no necessity, and the washing water is discharged to the human body part under appropriate water discharging conditions according to the excrement and the state of attachment. Therefore, the operation by the user is further simplified, and it is possible to eliminate the washing residue.

In a seventh aspect of the present invention, there is provided the human body local cleaning apparatus according to the second human body local cleaning apparatus, wherein the area detecting means detects an area of the skin surface to which the excrement discharged from the user is attached. Wherein the water discharge control means determines the water discharge condition of the washing water in accordance with the detection result by the area detection means. Even in this configuration, as described above, the parameters necessary for determining the water discharge condition (that is, the range of attachment to the skin surface of the user) are acquired by the area detection means, so that the selection by the user himself can be performed. It is not necessary, and the washing water is discharged to the human body part under appropriate water discharging conditions according to the size of the adhesion range. Therefore, the operation by the user is further simplified, and it is possible to eliminate the washing residue.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a human body cleaning apparatus according to an embodiment of the present invention. FIG. 1 is a configuration diagram centering on the flow path of water in the local human body cleaning apparatus according to the present embodiment. As shown in FIG. 1, the water passage of the human body local cleaning device 1 is provided with a water inlet side valve unit 10, a heat exchange unit 18, a flow control switching valve 21, and an electromagnetic pump 22 from an external water supply source (not shown). Is provided. The washing water is supplied by this electromagnetic pump 2
2 to the nozzle unit 30 through the bubble mixing unit 23 and the flow path switching valve 27.
The water is discharged from the water discharge holes formed in the nozzle body 31 as described later.

An upstream water supply pipe 11 connected to an external water tap, which is a water supply source, is connected to a water inlet 10 a of the water inlet valve unit 10. The washing water guided to the upstream water supply line 11 is subjected to a strainer 12 to remove suspended matters such as dust, and flows into a check valve 13 and a constant flow valve 14. When the downstream electromagnetic valve 15 is opened, the flush water adjusted to a predetermined flow rate by the constant flow valve 14 flows into the heat exchange unit 18 of the instantaneous heating method. It is preferable that the flow rate of the cleaning water flowing in after being adjusted in this manner is, for example, about 300 to 600 mL / min. Note that the upstream water supply pipe 11 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 10.

Inlet valve unit 10 and heat exchange unit 1
8 is connected to a drain pipe 17 with a relief valve 16 interposed. If the pressure in the pipeline on the upstream side of the relief valve 16 rises abnormally for some reason, the relief valve 16 opens and the washing water is discharged to the outside through the drainage pipeline 17.

The heat exchange unit 18 includes a heat exchange section 19 having a heater 191 therein. An unillustrated bimetal switch, a thermal fuse, and the like, which mechanically shut off abnormal heating thereof, are provided in close contact with or in proximity to the heater 191. In the heat exchange unit 18, the temperature of the washing water flowing into the heat exchanging unit 19 and the temperature of the washing water flowing out of the heat exchanging unit 19 are detected by the incoming water temperature sensor 192 and the outgoing water temperature sensor 193, respectively. Heat the water to the set temperature. The flow rate of the warmed washing water is adjusted by the flow control switching valve 21 so that the electromagnetic pump 22
Sent to

Further, the heat exchange section 19 is provided with a float switch 194 for detecting a water level inside the heat exchange section 19.
The float switch 194 detects that the heater 191 is at or above a predetermined water level at which the heater 191 is submerged.
Output the detection signal to Thus, the control unit 50 can supply power to the heater 191 only when the heater 191 is submerged, and can prevent so-called empty heating of the heater 191. Furthermore, the heat exchange unit 18
Is provided with a vacuum breaker 20 at a washing water outlet from the heat exchange unit 19. The vacuum breaker 20 cuts off the flow of the wash water in the pipe downstream of the heat exchange section 19 by introducing the atmosphere into the pipe, thereby preventing the back flow of the wash water from the flow control switching valve 21 side.

The flow control switching valve 21 adjusts the flow rate of the washing water to be sent to the electromagnetic pump 22, and removes dirt adhering to the nozzle itself at a predetermined time such as before and after local washing. It has a function of switching a flow path for discharging water.

The electromagnetic pump 22 includes a plunger that reciprocates upon excitation of an electromagnetic coil, and imparts coarseness and coarseness to the flow of washing water by the operation described below. Further, when the coarse and dense cleaning water passes through the bubble mixing section 24 included in the bubble mixing unit 23, appropriate bubbles are mixed into the cleaning water. The flow path switching valve 27 downstream of the bubble mixing section 24 is connected to the nozzle unit 3 for the supply destination of the washing water sent from the upstream.
It is switched to any one of the butt washing water passage 33, the soft washing water passage 34, and the bidet washing water passage 35.

The nozzle unit 30 includes a nozzle body 31
And a nozzle drive unit 32 that extends and retracts the nozzle body 31. At the ends of the buttocks washing water passage 33, the soft washing water passage 34, and the bidet washing water passage 35 provided inside the nozzle body 31, the buttocks water discharge holes 3 are provided.
6. Soft water discharge holes 37 and bidet water discharge holes 38 are formed. When the electromagnetic valve 15 of the water inlet side valve unit 10 is opened, the washing water heated by the heat exchange unit 18 and adjusted to a predetermined flow rate by the flow control switching valve 21 is supplied to the flow path switching valve 27.
Water is discharged from the water discharge hole of the water supply destination selected in.

Next, the structure and operation of the bubble mixing unit 23 will be described in more detail. In the air bubble mixing unit 23, the air pressurized by the air pump 25 is supplied to the air flow regulating valve 26.
The bubbles can be mixed into the washing water at a predetermined ratio by feeding the bubbles into the bubble mixing section 24 via the.

FIG. 2 is a schematic sectional view of the bubble mixing section 24.
In the figure, the washing water flows from left to right. Case 2
An air chamber 24 communicating with an air introduction pipe 243 is provided inside 41.
2 is formed, and on the inner peripheral side of the air chamber 242, there is provided a cylindrical bubble dispersion body 244 that allows the washing water to flow inside the washing water pipe continuously. The cell dispersion 244 is made of a porous material having a large number of micropores. The minute aperture has a minute size such that water does not seep to the outside at the pressure of the washing water passing through the inside, and air can be sent from the outside to the inside by a pressure difference between the inside and the outside. . For example, the cell dispersion can be formed by heating and molding substantially spherical particles of an ultrahigh molecular weight polyethylene resin.

When the flow rate of the air pressurized by the air pump 25 is controlled by the air flow regulating valve 26 and then sent to the air chamber 242 through the air introduction pipe 243, the air flows from the opening of the bubble dispersion body 244 into the pipe line. And swells at each hole location. When the bubbles expand to a predetermined size, the bubbles are cut off by the shearing force received from the washing water flowing in the pipeline, and are individually mixed into the washing water. For example, the cell dispersion 24 is formed so that the diameter of the formed cells is about 100 to 1000 μm.
The diameter of the opening 4 may be determined in advance. In this configuration, since the air mixing rate is determined according to the amount of air mixed into the washing water flowing in the pipeline, if the flow rate of the washing water is a certain amount, the air flow regulating valve 26 Of air (bubbles) can be determined by the opening degree of the air.

Next, the configuration of the nozzle unit 30 and the extension / retraction operation of the nozzle body 31 in the human body local cleaning apparatus 1 will be described in detail. FIG. 3 is a detailed configuration diagram of the nozzle unit 30. The nozzle unit 30 includes a driving pulley 41 that is rotationally driven by a nozzle driving motor (not shown in FIG. 3) that is a part of the nozzle driving unit 32, and two driven pulleys 42 and 43. Pulley 4
A timing belt (hereinafter, simply referred to as a “belt”) 44 having an inner peripheral surface formed in a saw-tooth shape is provided at 1, 42, and 43.
It is wound in a state where an appropriate tension is applied by the tensioner 45. The nozzle body 31 having the nozzle head 46 at the tip is fixed to the front of a nozzle holder 48 slidably provided on a nozzle guide 47. A latch 49 provided on the side of the nozzle holder 48 is provided.
Nip the belt 44 from above and below.

When the driving pulley 41 is driven to rotate in a predetermined direction (clockwise in FIG. 3) by the nozzle driving motor, the belt 44 is inclined with the nozzle holder 48 between the driven pulleys 42 and 43. The nozzle body 31 moves forward and downward, whereby the nozzle body 31 extends obliquely forward and downward. When the nozzle drive motor rotates the drive pulley 41 in the reverse direction, the nozzle body 31 retreats obliquely upward and rearward. In this way, the nozzle head 46 is extended from the predetermined standby position to the buttocks cleaning position or the bidet cleaning position in front of it, or conversely, is retracted from those cleaning positions to the original standby position.

The tail water outlet 36, the soft water outlet 37, and the bidet water outlet 38 provided in the nozzle head 46 have:
A predetermined trajectory water discharge control means is provided for controlling the cleaning water discharged from the water discharge hole to draw a predetermined trajectory. In the human body local cleaning device 1, the predetermined trajectory water discharge control means includes an armature that generates a magnetic field when energized, and a movable body that is magnetized by itself and moves by interaction with the magnetic field generated by the armature. Actuator as a main component.

Next, the structure and operation of this actuator will be described with reference to FIG. FIG. 4 is a schematic sectional view (a) and a perspective oblique view (b) showing a configuration of a main part of the nozzle head 46. In FIG. 4, only the configuration of the predetermined trajectory water discharge control means related to the bidet water discharge hole 38 is described, and the description of the ass washing or the soft cleaning related elements is omitted. The soft water discharge hole 37 is also provided with a predetermined trajectory water discharge control means having the same or similar configuration.

In FIG. 4, the movable body 60 having a substantially cylindrical shape has a moving water passage 62 therein, and the upper opening of the moving water passage 62 is the bidet discharge hole 38. The moving water passage 62 is connected to the bidet washing water passage 35 provided inside the nozzle body 31 by a stretchable joint pipe 63 such as a rubber pipe or a bellows-shaped pipe. The washing water is circulated through. Movable body 60
A ring-shaped ferromagnetic body 61 is integrally provided on the outer peripheral side, and a ring-shaped electromagnetic coil 65 is disposed outside the gap with a gap 64 therebetween. Since the electromagnetic coil 65 is buried inside the nozzle head 46, it does not get wet and high reliability can be maintained for a long time.

As shown in FIG. 4B, the electromagnetic coil 65
Has a structure radially divided into a plurality in the circumferential direction. When current is applied to any of the plurality of electromagnetic coils 65, a magnetic field is generated in a space surrounded by the electromagnetic coils 65, and an attractive force or a repulsive force acts on the ferromagnetic material 61. As described above, the movable body 60 includes the elastic joint pipe 6.
3, any movement is possible within the space 64 in the radial direction with respect to the axis C. Therefore, the movable body 60 moves in the direction of the energized electromagnetic coil 65 or in the opposite direction. By controlling the energization of the electromagnetic coil 65, the movable body 60, that is, the bidet discharge hole 3 is controlled.
Reference numeral 8 rotates, substantially rotates or swings around the axis C without rotating. By appropriately controlling the drive current, it is possible to change not only the moving direction of the movable body 60 but also the magnitude and speed of the movement (in the case of repetitive movement, the period).

FIG. 5 is a schematic diagram showing an example of the trajectory of the washing water discharged from the bidet water discharge hole 38. For example, if the cleaning water is discharged from the bidet water discharge hole 38 while controlling the energization of the electromagnetic coil 65 so that the bidet water discharge hole 38 rotates in a spiral shape, the cleaning water is moved with the movement of the water discharge hole 38. Draw a trajectory that spirals. Although the area of the region 70 on the object to be washed with the washing water is small when viewed instantaneously, the region 70 moves according to the above-mentioned trajectory, and the washing water can be applied to the whole of the wide washing range 71. Further, the area of the cleaning range 71 can be appropriately set according to the control of energization of the electromagnetic coil 65. Note that the actuator used here is disclosed by the present applicant in Japanese Patent Application No.
169767 is one of the proposals.

Further, the above-mentioned predetermined trajectory water discharge control means means that the discharged cleaning water is swirled in a so-called spiral shape. The washing water is applied intermittently in the local area. That is, this corresponds to spatial intermittent water discharge. In such an intermittent water discharge, it is possible to avoid a stimulus having a substantially constant intensity from continuing to the local area.

Next, the operation of the electromagnetic pump 22 in the body part cleaning apparatus 1 will be described in detail. This electromagnetic pump 2
The main function of 2 is to control the reciprocating speed and cycle of the plunger appropriately as described above, and
To provide the flow of the washing water discharged from the nozzles 38 to 38 with density. FIG. 6 is a diagram schematically showing the water discharge state at this time. FIG. 6A shows a case where a discontinuous water mass is discharged from the bidet water discharge hole 38 (of course, the other water discharge holes 36 and 37 may be used). (B) shows an example in which the discharged washing water has a pulsation, that is, the water pressure (or the instantaneous flow rate or flow rate) fluctuates with time. In the case of (b), the water flow is always present, so it cannot be said that the water flow is strictly intermittent, but here, such pulsating water discharge is also referred to as intermittent water discharge.

In such an intermittent water discharge, if the intermittent frequency is increased, the user cannot sense the contact of the discontinuous water mass or the fluctuation of the flow rate, and as if the washing water of the substantially constant flow rate is continuously applied. Feel the irritation. On the other hand, if the intermittent frequency is lowered, it becomes easier to sense the contact of each water mass or the fluctuation of the flow rate, thereby increasing the sense of irritation. Further, by performing intermittent water discharge in this manner, the instantaneous flow velocity can be increased while reducing the amount of water used. Therefore, there is an advantage that the amount of water used can be greatly reduced when obtaining the same level of cleaning performance. The electromagnetic pump 22 used here is one of the wave generation devices in the human body local cleaning device proposed by the present applicant in Japanese Patent Application No. 11-112812 (see Japanese Patent Application Laid-Open No. 2000-8453). This is an example, and the present invention is not limited to this configuration as long as a similar function can be achieved.

The seven operation keys denoted by reference numerals a to 52g are collectively referred to as “cleaning mode selection keys”.

The use of the two selectable modes is generally as follows. When cleaning your ass,
Normally, the “rigid mode” is selected. However, if a strong cleaning jet is not desired, for example, when suffering from hemorrhoids, the “careful mode” is selected. In the case of menstrual washing, if the washing is to be performed at a point in time after the vaginal menstrual blood has passed, select the "daytime mode", for example, wash the menstrual blood that occurred while sleeping in the morning and after getting up. In some cases,
In the case where the washing is performed after a lapse of time from the menstrual time, the “wake-up mode” is selected. In addition, when washing a veneer, literally, if the viscosity of the vagina is low (high fluidity), select the "smooth mode". If the viscosity is high and sticky, select the "sticky mode". I do.

In the human body local cleaning apparatus 1 according to the present embodiment,
When one of the cleaning mode selection keys is operated on the operation panel, the discharge of the cleaning water is controlled under predetermined conditions according to the selected cleaning mode. Next, the cleaning operation in the human body local cleaning device 1 will be described in detail.

When the human body cleaning device is not used, the nozzle body 31 is retracted to the rearmost position so that the nozzle body 31 does not obstruct defecation. When the user sits on the toilet seat, the seating sensor 5
The control unit 50 recognizes the seating based on the seating detection signal from 3.

When the user operates one of the washing mode selection keys on the operating section 52 after sitting or after urinating or defecation, the control section 50 receives the key input signal and the control section 50 selects the washing water first. The flow path of the flow path switching valve 27 is set so as to flow into the water passage corresponding to the function. Specifically, a flow path is set to the hip washing water passage 33 during normal ass washing, to the soft washing water passage 34 during soft ass washing, and to the bidet washing water passage 35 during physiological washing, vaginal washing, and urine washing. I do. The control unit 50 also controls the nozzle drive motor 32
1, the drive pulley 41 is rotated clockwise in FIG. 3 by a predetermined angle. Then, the belt 44 operates clockwise in conjunction with the rotation of the driving pulley 41, and the nozzle holder 48 fixed to the belt 44 via the latch 49 moves forward. When the drive pulley 41 rotates by a predetermined angle, the nozzle head 4
6 reaches the human body part.

FIG. 8 is a schematic diagram showing the positional relationship between the nozzle head 46 and the human body part (ie, the anus, vagina entrance or urethral entrance) in the human body part cleaning apparatus 1. When the nozzle head 46 is located at the rearmost position L1, the washing water discharged from the buttocks discharge hole 36 reaches the anus and its surroundings. When the nozzle head 46 extends to the position of L2, the washing water discharged from the bidet discharge hole 38 reaches the vaginal entrance and its surroundings. When the nozzle head 46 further extends and reaches the position L3, the washing water discharged from the bidet water discharge hole 38 reaches the female urethral entrance and its surroundings. However, this is a principle and, for example, a bidet spout 38
It is also possible to wash the area near the anus with the washing water discharged from the toilet.

In this human body local cleaning device, the flow rate, amount of water, air mixing ratio, frequency of intermittent water discharge or pulsating water discharge (hereinafter simply referred to as “water discharge water”) is discharged from the water discharge holes 36 to 38 in correspondence with each of the above-described cleaning modes. Various water discharge conditions such as a “frequency” and a cleaning range are respectively changed. FIG. 10 shows the settings of these water discharge conditions for each cleaning mode. The flow velocity is selected from three stages of large, medium and small, the water volume is selected from three stages of high, medium and small, the air mixing ratio is selected from three stages of high, medium and low, and the frequency is high, medium and low It is selected from three low levels. In addition, the cleaning range is set in the front-rear direction and the lateral direction with respect to three local portions: the urethral entrance, the vaginal entrance, and the anus. The set value of each water discharge condition is determined appropriately.

Here, a method of defining the water discharge condition for the cleaning mode will be described. First, at the time of urine washing, excretion is only urine, so that excrement attached to the skin (urethral entrance) has a low viscosity and is very easy to remove. Therefore, the flow velocity is small and the amount of water is small. As a result, the amount of water used can be reduced. In addition, the air mixing rate is increased and the frequency is also increased. This provides a very soft feeling when the wash water reaches the skin.

Although vaginal discharge is generally higher in viscosity than urine, the viscosity varies considerably depending on physical conditions and the like. In particular, when the viscosity is high, it sticks to the skin and is difficult to remove.
Therefore, in washing the vaginal discharge, a strong water force is obtained in the "sticky mode" by increasing the flow velocity and reducing the air mixing rate as compared with the "smooth mode". Also, in the "sticky mode", the vaginal discharge is difficult to spread near the vaginal entrance, whereas in the "smooth mode" it is easy to spread, so that the latter has a wider washing range than the former. In addition, since the vaginal entrance is a delicate part, in the "smooth mode", the air mixing rate is increased and the frequency is increased to reduce irritation to the human body.

In the "daytime mode", which assumes that the blood is still in a liquid state immediately after excretion of the blood in the menstrual washing, although the viscosity is not so high, it is easy for the blood to spread to the urethral entrance side, It is necessary to consider that it is a delicate part. Therefore, the water force is not increased unnecessarily, the frequency is increased to reduce irritation to the human body, and the washing range is extended to the urethral entrance. On the other hand, in the "wake-up mode", which assumes a long time after blood adheres to the skin, such as when waking up, the blood adhering to the skin may be oxidized by air and almost solidified. is there. Therefore, for such dirt, the cleaning performance is the highest, that is, the flow rate is large, the amount of water is large, the mixing ratio of air is low, and the frequency is low. In addition, when menstrual blood occurs during bedtime, the dirt often spreads in a considerably wide area in the front-rear direction, so that a wide area from the urethral entrance to the anus is to be cleaned.

Further, in the ass washing, in the “rigid mode”, a combination that provides the highest washing performance is obtained in the same manner as in the “wake-up mode”, and the washing range is narrowed down to a very narrow range around the anus. On the other hand, in the "attentive mode", assuming that the user is suffering from hemorrhoids, diarrhea, etc., the flow rate and the amount of water are reduced so as to avoid strong irritation, and the air mixing ratio is increased. In addition, the washing range is slightly widened in consideration of the spread of the stool.

Among the above water discharge conditions, the amount of water and the flow rate are determined by the opening of the flow control switching valve 21 and the delivery pressure of the electromagnetic pump 22. In this example, for the combination of the flow rate and the water amount shown in FIG.
Is appropriately adjusted. The air mixing ratio is adjusted by the opening degree of the air flow regulating valve 25 as described above. The frequency is adjusted by the operating frequency of the plunger of the electromagnetic pump 22. Furthermore, the cleaning range is basically adjusted by the excitation control of the electromagnetic coil 65 of the actuator. However, since there is a limit to the increase in the cleaning area due to the movement of the water discharge holes 36 to 38 as described above, for example, the physiological " When the cleaning range extends over a plurality of local areas, such as in the "daytime mode" or the "wake-up mode", so-called move cleaning using both extension and retreat operations of the nozzle body 31 by the nozzle driving unit 32 is performed. That is, when any one of the seven types of cleaning modes is selected, the flow control switching valve 21, the electromagnetic pump 22, the air flow control valve 2,
5. The electromagnetic coil 65 and the nozzle drive motor 321 are controlled as programmed in advance.

The initial cleaning position of the nozzle head 46 at the start of water discharge according to the cleaning range (for example, L1, R2 shown in FIG. 8)
L2 or L3) is determined. When the nozzle head 46 reaches the initial cleaning position from the standby position, the control unit 50 appropriately sets the opening of the flow control switching valve 21 and sets the water inlet side valve unit. The solenoid valve 15 of 10 is opened. Then, the washing water flows into the heat exchange unit 19, and the warmed washing water passes through the flow control switching valve 21, is made coarse and dense by the electromagnetic pump 22, and bubbles are mixed at an appropriate ratio by the bubble mixing unit 23. After that, it is sent out to the previously selected water channel. For example, at the time of washing the vagina, the hot water that has passed through the bidet washing water passage 35 flows into the moving water passage 62 through the connecting pipe 63 and is ejected from the bidet discharge hole 38. At this time, by appropriately energizing the electromagnetic coil 65, the warm water spouting from the bidet water discharge hole 38 draws a predetermined trajectory as shown in FIG. Allow wash water to reach.

The following control is performed during the above-mentioned move cleaning operation. FIG. 11 utilizes this move cleaning.
It is a perspective view which shows the water discharge state in "sleep-up mode" of menstrual washing. In the move cleaning, the reciprocating motion of the nozzle main body 31 by the forward / reverse rotation of the nozzle drive motor 321 and the excitation control of the electromagnetic coil 65 adjusted to the position of the nozzle head 46 are simultaneously executed. For example, when the nozzle head 46 is located substantially at the center position (the cleaning position Wc) of the range of reciprocating movement of the nozzle, the excitation control of the electromagnetic coil 65 is performed so that the moving range of the movable body 60 is maximized. Then, the excitation control of the electromagnetic coil 65 is changed continuously or stepwise so that the moving range becomes narrower as the nozzle head 46 moves away from the center position to the extension end position Wf and the retreat end position Wb. As a result, as shown in FIG. 11, it is possible to move and clean a wide area in the front-rear direction of the human body local part such that the cleaning area is large near the center position and the cleaning area becomes narrower toward the extended end and the retracted end.

Thus, according to the human body local cleaning device 1,
The cleaning according to the cleaning mode selected by the user is performed. If necessary, the “front wide” key 52
h, "Wide Wide" key 52j and "Back Wide" key 52
By operating k, the cleaning range can be freely (but within a predetermined range) expanded in the forward, lateral, and rearward directions. For example, the range of attachment of blood during menstruation greatly varies among individuals such as posture and body shape, and especially when sleeping, dirt may spread over a considerably wide area in the front-rear and lateral directions. In order to cope with this, it is necessary not only to widen the washing range in the front, rear, left and right around the reference position, but also to widen the washing range only in the direction required by the individual, and not to wet other portions. Therefore, the three wide keys 52h, 52j, 5
By using 2k individually or in combination of two or more, more preferable washing without residual washing can be achieved. Here, the expansion of the cleaning range in the horizontal direction corresponding to the “wide wide” key 52j can be performed by drive control of the actuator.
The expansion of the front and rear cleaning ranges corresponding to the h and the "rear wide" key 52k may be performed by using both the drive control of the actuator and the reciprocating movement of the nozzle back and forth (that is, move cleaning). .

Thereafter, when the user operates a stop key (not shown) on the operation panel 52, the control unit 50 receives the key input signal and closes the electromagnetic valve 15 of the water inlet side valve unit 10. This stops the discharge of warm water from the water discharge holes 36 to 38. Further, the control unit 50 appropriately supplies electricity to the nozzle drive motor 321 with a polarity opposite to the predetermined polarity, and rotates the drive pulley 41 counterclockwise by the predetermined angle. Thus, the nozzle head 46 returns from the cleaning position to the standby position, and the cleaning is completed.

Next, a human body cleaning apparatus according to another embodiment of the present invention will be described. This device eliminates the need for user operation required in the device of the above embodiment. FIG. 12 is an electrical configuration diagram of a main part of the human body local cleaning apparatus according to this embodiment. In this human body local cleaning device, in addition to the human body local cleaning device 1, a viscosity measuring unit 80 that temporarily collects excrement that has fallen into the toilet and measures the viscosity of the excrement is used. Imaging section 81 such as a CCD image sensor for photographing a predetermined range including the local area of the user
An attachment area identification unit 82 that receives an image signal from the imaging unit 81 and recognizes an attachment area of excrement, and a non-contact measuring unit that measures the water content of excrement adhering to the skin of the user. And a moisture content measuring unit 83 such as a microwave transmission type moisture meter.

The control unit 50 receives signals from these units, receives a key input signal corresponding to the type of excrement designated by the user through the operation panel 52, and uses a washing water suitable for washing the excretion. Automatically select the flow rate, water volume, air mixing ratio, frequency and cleaning range. FIG.
Is an example showing the selection criteria at this time. Depending on the type of excrement, other water discharge conditions except the washing range are set,
Using the information on the viscosity of the excrement obtained from the viscosity measuring section 80 and the information on the water content of the attached matter obtained from the water content measuring section 83, the previously set water discharge conditions are corrected. Thereby, appropriate cleaning can be performed according to the type of excrement and its condition.

The above embodiment is merely an example, and it is apparent that modifications and modifications can be made as appropriate within the scope of the present invention. Specifically, for example, the following points can be changed.

For example, in the above embodiment, the water discharge holes 36 to 38
Is one, but may be an aggregate of a plurality of water discharge holes.

The predetermined trajectory water discharge control means may employ various methods as long as the trajectory of the washing water discharged from the water discharge hole can be changed. For example, a motor for rotating the movable body about an axis is provided by indirectly connecting the movable water passage provided on the movable body and the immovable water passage provided on the nozzle body side. Then, while the movable body is rotated by the motor, the washing water supplied from the immovable water passage to the moving water passage is jetted from the water discharge hole, so that the washing water draws a predetermined trajectory. Of course, an appropriate power transmission mechanism such as a gear or a crank may be interposed between the motor and the movable body.

Further, the movable body provided with the ferromagnetic material is configured to be swingable in the nozzle width direction within a predetermined angle range with respect to the axis C, and two or By appropriately controlling the excitation of one electromagnetic coil disposed on one side, the inclination of the movable body is controlled, whereby the direction of jetting of the water discharged from the water discharge hole is changed so that the cleaning water draws a predetermined trajectory. It may be. That is, in the present invention,
Since it is only necessary to be able to freely change the area of the washing area,
The water discharge hole does not need to be rotatable and can be moved only on one axis in the width direction, and the washing area and its shape are appropriately set using the extension and retreat movement of the nozzle as described above. can do.

Also, as described above, the nozzle head 46
Can be moved not only in the front-back direction but also in the left-right direction, and the washing water discharged by this movement may draw a predetermined trajectory. In addition, the predetermined trajectory water discharge control means can perform various modifications. The present applicant has already proposed the configuration of such means and details of its operation in Japanese Patent Application No. 11-169767.
