Abstract

PROBLEM TO BE SOLVED: To effectively accelerate circulation of the blood by bringing alternately warm water and cold water into contact with a wide range of the neighborhood of private parts of a human body and sufficiently increasing the temperature difference especially for the purpose of therapy and prevention of hemorrhoids. SOLUTION: A warm water flow path and a cold water flow path are independently arranged in a nozzle body and a movable body 61 wherein a water passage connected with both flow paths respectively with flexible connecting tubes is provided. While the warm water and the cold water are respectively approximately simultaneously discharged from a warm water discharging hole 64a and a cold water discharging hole 64b, energization of electricity to an electromagnetic coil is controlled and the movable body 61 is moved back and forth in a gap 66 in which a magnetic field is formed thereby. As a result, being accompanied with the movement back and forth, the cleaning water reaching a lesion part 81 of a user is alternately switched between the warm water and the cold water. When the movement of the movable body 61 is appropriately controlled, as the warm water and the cold water are quickly switched and the large temperature difference before and after switching can be kept, it is possible thereby to effectively perform warm-cold therapy.

Description

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 Hemorrhoids are roughly classified into hemorrhoids known as wart hemorrhoids, anal fissures known as cut hemorrhoids, and anal fistulas. The most common of these is hemorrhoids, mainly due to congestion of the anus, and promotion of blood circulation is necessary for prevention and treatment.

[0003] In order to easily promote blood circulation in the vicinity of the anus at home, a human body configured to wash out dirt adhering to a local part of the human body by ejecting washing water from a nozzle toward a local part of the human body. A local cleaning device is useful.
In general, in a human body local cleaning apparatus, hot water having an appropriate temperature can be discharged from a nozzle. Therefore, by applying such hot water to an affected part, a blood vessel is expanded and blood circulation is promoted. Of course, it can be expected that the blood vessel is mechanically stimulated by spraying water onto the affected area, and that blood circulation is promoted by the same effect as massage.

In order to further promote blood circulation, it is effective to alternately apply hot water and cold water alternately to the diseased part, instead of simply making the hot water only continuously reach the diseased part. That is, when cold water is applied to the affected area, the blood vessels temporarily contract, and then when hot water is applied to the affected area, the blood vessels expand suddenly due to the recoil, greatly helping to promote blood circulation. There is also a secondary effect of strengthening the blood vessel wall by repeatedly contracting and expanding the blood vessel. In the following description, such an effect is collectively referred to as a “warming effect”.

[0005] Several human body cleaning devices mainly intended to treat hemorrhoids by focusing on such points have been known. For example, Japanese Patent Publication No. 4-10539
Japanese Patent Application Laid-Open No. 10-338960 and Japanese Patent Application Laid-Open No. 10-338960 have a configuration in which hot water and cold water are alternately injected at a predetermined cycle from a nozzle toward a human body part. Also, Japanese Patent Application Laid-Open No. 11-309196 discloses a human body that performs temperature control such that relatively high temperature water and low temperature water are alternately jetted and the temperature rises as time passes as a whole. A local cleaning device is described.

[0006]

However, such a conventional human body part cleaning apparatus has the following problems. The first is the problem of the temperature of the water injected from the nozzle. That is, as a method of switching between hot water and cold water, there are a method of alternately obtaining hot water and cold water by ON / OFF control of a heater, a method of switching between cold water and hot water by an electromagnetic valve, and the like. In the method of controlling the energization of the heater, it is necessary to prepare a heater capable of rapidly raising and lowering the temperature in accordance with the energization control. However, in practice, it is not possible to rapidly change the temperature of the water. It is difficult, and the effect of promoting blood circulation is diminished by a gradual change in temperature at the time of switching between hot water and cold water. In addition, in the method of switching the flow path using an electromagnetic valve or the like, although switching between hot water and cold water by the electromagnetic valve itself can be performed in a relatively short time, when switching through a water passage from the electromagnetic valve to the water discharge hole of the nozzle. Due to the heat exchange with the water passage wall, the temperature change of the water actually discharged from the water discharge port becomes gentle, and the effect of promoting blood circulation is also weakened.

[0007] The second problem is the size of the affected area that can promote blood circulation. That is, in the conventional human body local cleaning device, since the temperature of the cleaning water applied to a relatively small affected area is changed, the effect of promoting blood circulation is very limited, and a satisfactory therapeutic effect for hemorrhoids is always obtained. I couldn't do that. In addition, since a general human body local cleaning device has a structure in which the nozzle itself can be moved, the nozzle is swung by using such a moving mechanism, and hot water or cold water is applied to a wider affected area. It is possible. However, in this case, it is necessary to synchronize the nozzle swing control and the hot / cold water switching control in a predetermined relationship, and there is a problem that the control becomes complicated.

[0008] The present invention has been made in view of the above problems, and an object thereof is to provide a simple configuration.
It is an object of the present invention to obtain a human body local cleaning apparatus which is particularly suitable for treating and preventing hemorrhoids by effectively treating a large affected area with heat and cold.

[0009]

According to a first aspect of the present invention, there is provided a human body cleaning apparatus according to the present invention, wherein cleaning water discharged from a spout provided in a nozzle reaches a local body of a human body. A) a plurality of water outlets provided in one or more nozzles; and b) the temperature of the wash water discharged from each of the plurality of water outlets at substantially the same time. Water supply means including water temperature adjusting means for heating and / or cooling the wash water so as to be different from each other by at least two or more; c) the wash water discharged from the plurality of water outlets draws a predetermined trajectory And a predetermined trajectory water discharge control means for performing control as described above.

[0010] Here, the water discharge port is an opening provided at an end of a water passage provided inside the nozzle.
One water outlet is provided corresponding to the water passage. Further, each of the plurality of water outlets may have a configuration of one water outlet, but may have a configuration of a plurality of water outlets.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION That is, in the apparatus for cleaning a human body part according to the present invention, one or more nozzles include:
A first water outlet comprising one or more water outlets for discharging cleaning water having a first water temperature, and a first water outlet having a second water temperature different from the first water temperature. And at least a second water discharge port comprising one or more water discharge holes for discharging the cleaning water substantially simultaneously with the discharge water. Wash water heated or cooled by the water temperature adjusting means is sent out in parallel to the first and second water outlets, respectively. The first and second water outlets may be provided in the same nozzle, or may be provided in different nozzles. Also, since there is only a difference between the first and second water temperatures, only one of the washing waters is heated or cooled, and the other is sent out as it is, that is, the water supplied from, for example, a faucet or the like is sent out as it is. May be. However, the water passages from the water temperature adjusting means to the first and second water outlets are provided independently for each of the water temperatures, so that one is not affected by the other water temperature.

The cleaning water having a temperature difference discharged from the first and second water outlets substantially simultaneously reaches different parts close to the human body. When the plurality of cleaning waters are controlled to draw a predetermined trajectory by the predetermined trajectory water discharge control means, the cleaning water having the first water temperature at a certain point in time in a predetermined local part of the human body with the movement of the cleaning water. And at other times the washing water having the second water temperature arrives. In other words, relatively high temperature cleaning water and low temperature cleaning water alternately hit a predetermined local area, thereby obtaining a high temperature cooling effect.

[0013] According to the configuration of the human body local cleaning apparatus, hot water and cold water are guided to different water outlets through independent water passages and are respectively discharged, and the discharged plurality of cleaning waters move to move the hot water and the cold water. Substantial switching with cold water is achieved. Therefore, the temperature difference between the hot water and the cold water becomes the temperature difference before and after the switching between the hot water and the cold water that hits the affected part, and the effect of contracting and expanding blood vessels is large, and blood circulation can be promoted extremely effectively. Further, by controlling the movement trajectory of the washing water by the predetermined trajectory water discharge control means, it is possible to heat and cool a wide range of parts. Therefore, the effect of promoting blood circulation is not localized, but can be obtained, for example, over a wide area around the anus, which is extremely effective in treating and preventing hemorrhoids.

For the treatment of hemorrhoids and the reduction of their pain,
In some cases, it is effective to heat or cool a specific site intensively depending on the symptoms while heating / cooling a wide area instead of simply heating / cooling a wide area. Therefore, in the human body local cleaning device according to the present invention, the predetermined trajectory water discharge control means may be configured so that the speed at which the trajectory is drawn is not constant within one cycle. According to this configuration, the time during which the hot water is applied or the time during which the cold water is applied varies depending on the location, and the intensive heating or cooling as described above can be realized. Here, "the speed at which the trajectory is drawn is not constant within one cycle" also includes temporarily stopping during that cycle.

The predetermined trajectory water discharge control means can take various forms. In one embodiment, for example, the direction of the cleaning water discharged from the water discharge port can be switched substantially periodically using a fluid oscillation element utilizing the Coanda effect (fluid adhesion effect). According to this configuration,
Unlike other embodiments which will be described later, no mechanical power source such as a motor is required, so that the structure is extremely simplified, which is advantageous for miniaturization and at low cost.

Further, as another embodiment of the predetermined trajectory water discharge control means, it is possible to move one or more nozzles as a whole. Normally, in this type of human body local cleaning device, the nozzle is retracted to a retracted position (storage position) so as not to be obstructed during defecation, and only when a switch for instructing cleaning is operated, the nozzle is moved to the buttocks of the user. It is moved to advance downward. Since the nozzle is provided with a nozzle drive mechanism for performing such advance / retreat, the nozzle is used to move the entire nozzle, thereby ejecting a flush water to reach a predetermined local portion. Can be replaced. According to this configuration, although a mechanical power source is required, the mechanical power source and the drive mechanism required for the present apparatus can be used in the first place, so that the increase in cost is extremely small. Also,
In the configuration using the above-described fluid oscillation element, the switching cycle of the discharge direction of the washing water depends on the flow rate, so that the switching cycle and the flow rate cannot be independently variably controlled. Is possible.

Further, as another embodiment of the predetermined trajectory water discharge control means, the plurality of water discharge ports are provided in one nozzle, and the predetermined trajectory water discharge control means is configured such that the plurality of water discharge ports are provided with respect to the nozzles. It may move in a predetermined trajectory around an axis inside the nozzle. According to this configuration, the moving portion is smaller than when the entire nozzle is moved along a predetermined locus, so that it is easy to reduce the generation of vibration and noise due to driving. Further, since the moving speed of the predetermined trajectory can be increased, the replacement cycle of hot water and cold water can be set freely in a wider range.

Further, the above configuration may include a moving body that moves on a predetermined trajectory without rotating around the axis. Specifically, for example, between a moving water passage that moves along a predetermined trajectory and an immovable water passage that does not move, without having a seal portion provided for the purpose of preventing leakage of cleaning water, when there is a seal portion Similarly, the washing water can be moved along a predetermined trajectory. Therefore, there is no need to make the drive mechanism unnecessarily large, and the nozzle can be downsized. Further, since there is no seal portion in which abrasion is particularly a problem, occurrence of troubles such as failures can be significantly reduced, and reliability can be improved.

The predetermined trajectory water discharge control means includes an armature that forms a magnetic field that changes with time in a predetermined closed space, and an armature that is disposed in the magnetic field and interacts with the magnetic field to generate a magnetic field in the predetermined closed space. And a movable element that moves along a predetermined trajectory, and the movable element may be provided with the plurality of water outlets. In this configuration, since the mover moves due to the magnetic interaction between the armature and the mover, no shaft or other mechanism connected or connected to the mover to drive the mover is required. is there. Therefore, according to this configuration, since a rotary power drive source such as a motor and a complicated power transmission mechanism are not required, the configuration is simple and energy loss is small. Further, there is no limitation that the movable object can be moved only according to a specific trajectory as in the case of using a general motor, and the trajectory can be arbitrarily moved in a closed space. Therefore, the degree of freedom such as the position of the part to be heated and cooled and its size is very large.

In the apparatus for cleaning a human body local part according to the present invention, both hot water and cold water can be discharged substantially continuously, but the discharge is appropriately controlled in conjunction with the movement of the water discharge port. Thereby, for example, it is also possible to eliminate or reduce a portion to which only hot water is applied or a portion to which only cold water is applied. In addition, the meaning of "substantially continuously discharged" means
It means that it is sensory and continuous for the user. In other words, for example, when water is intermittently sprayed in a short cycle, it cannot be said that it is strictly continuous discharge, but the user cannot sense the period in which water does not hit, as if the water hits continuously. I perceive it as being. In such a case, it can be said that the ink is discharged substantially continuously.

Moves diagonally forward and downward with the nozzle holder 57, whereby the nozzle body 44 advances diagonally forward and downward. When the nozzle drive motor 59 drives the drive pulley 51 to rotate in the reverse direction, the nozzle body 44 retreats obliquely upward and rearward.

The nozzle head 60 is provided with water discharge holes communicating with the anal cleaning hot water flow channel 45, the bidet cleaning water flow channel 46, and the cold water flow channel 47, respectively. The water discharge port of the passage 47 is provided with a water discharge section drive mechanism for moving the water discharge hole itself with a predetermined trajectory. In this embodiment, the water discharge section driving mechanism corresponds to the predetermined trajectory water discharge control means of the present invention.

Next, the water discharge section drive mechanism will be described. FIG. 4 is a schematic cross-sectional view (a) and a perspective oblique view (b) showing a configuration of a main part of the nozzle head 60. In this figure, the description of the components related to the bidet cleaning is omitted. The water discharge section drive mechanism is composed of an actuator having, as main components, an armature that generates a magnetic field when energized and a movable body that itself has magnetism and moves by interaction with a magnetic field generated by the armature.

In FIG. 4, a substantially cylindrical movable body 61 has a hot water passage 63a and a cold water passage 63b therein.
The upper ends of the water passages 63a and 63b are opened as a hot water discharge hole 64a and a cold water discharge hole 64b. Hot water channel 63a
And a cold water flow passage 63b, the anal cleaning hot water flow passage 45 and the cold water flow passage 47 disposed inside the nozzle body 44,
The pipes are connected by elastic connecting pipes 65a and 65b such as rubber pipes or bellows-like pipes, and water flows through the connecting pipes 65a and 65b. An annular ferromagnetic body 62 is integrally provided on the outer peripheral side of the movable body 61, and an annular electromagnetic coil 67 is provided outside the movable body 61 with a gap 66 therebetween. Electromagnetic coil 67
Since the is embedded in the nozzle head 60, it is not flooded, and high reliability can be maintained for a long period of time.

The electromagnetic coil 67 has a structure radially divided into a plurality in the circumferential direction.

With the movement of the cleaning water, the cleaning water also moves while drawing a predetermined trajectory. The actuator used here is one of those already proposed by the present applicant in Japanese Patent Application No. 11-169767.

FIG. 3 is a block diagram of the electrical system of the main part of the apparatus for cleaning a human body part according to the present embodiment. At the center of the control, a control unit 70 using a microcomputer or the like is installed. The control unit 70 includes a plurality of operations such as an anal cleaning key 72a, a bidet cleaning key 72b, a hemorrhoid treatment key 72c, and a stop key 72d. A key input signal is input from an operation panel 72 having keys, a seat detection signal is input from a seat sensor 73 provided on the toilet seat, and a water temperature detection signal is input from the temperature sensors 18 and 26. The control unit 70 receives the input signals, performs a predetermined process, and performs a predetermined process through the load driving unit 71.
3, heater 17, cooler 25, flow regulating motors 22, 30,
The first on-off valve 31, the second on-off valve 32, the cold water on-off valve 33, the nozzle drive motor 59, and the electromagnetic coil 67 are appropriately controlled.

Next, in this human body local cleaning device,
The operation during normal anal washing will be described. When the user sits on the toilet seat, the control unit 70 recognizes the seating based on the seating detection signal from the seating sensor 73. At this time, the nozzle body 4
4 is retracted to the rearmost position, so that the nozzle body 44 does not obstruct defecation. When the user operates the anal cleaning key 72a on the operation panel 72 after defecation, the control unit 70 drives the nozzle drive motor 59 to advance the nozzle body 44 integrally to the anal cleaning position as described above, and the valve unit 11 solenoid valves 1
3, and the first on-off valve 31 is opened. Then, water flows into the heat exchanger 16 and is pushed by the water, so that the water
The hot water stored in the first flow control unit 19 and the first
After passing through the on-off valve 31, it is sent to the anal cleaning hot water flow channel 45 of the nozzle unit 40. Then, as described above, the hot water flows into the hot water passage 63a through the connecting pipe 65a, and is ejected from the hot water spouting hole 64a. At this time, the electromagnetic coil 67
In this case, the hot water spouting from the hot water spouting hole 64a moves so as to draw a predetermined trajectory, and a wide area near the user's anus can be washed.

Next, the operation during the treatment of hemorrhoids which is characteristic in this embodiment will be described with reference to FIGS. FIG. 5 is a schematic diagram of a cleaning operation during hemorrhoid treatment, and FIG. 6 is a diagram illustrating a temperature change of cleaning water reaching an affected part (predetermined human body part) of a user.

When the user operates the hemorrhoid treatment key 72c on the operation panel 72 while sitting on the toilet seat, the controller 70
Moves the nozzle body 44 integrally to the anal cleaning position to open the electromagnetic valve 13 and open both the first on-off valve 31 and the cold water on-off valve 33. Thus, the hot water heated to the predetermined first temperature Th by the heating unit 15 is pressure-fed to the anal cleaning hot water flow path 45 of the nozzle unit 40 in the same manner as described above. On the other hand, since the chilled water on-off valve 33 is also opened, the chilled water cooled to the predetermined second temperature TL by the cooling unit 23 is pumped into the chilled water channel 47 of the nozzle unit 40.

At this time, by applying a predetermined current to the electromagnetic coil 67, the movable body 61 is reciprocated at a predetermined frequency in the front-rear direction. Anal wash hot water channel 45
The hot water and the cold water that have passed through the cold water flow path 47 simultaneously spout upward from the hot water discharge holes 64a and the cold water discharge holes 64b, respectively, and the movable body 61 provided with the hot water discharge holes 64a and the cold water discharge holes 64b reciprocates. As a result, the parts reached by the water jetted from the water discharge holes 64a and 64b move.

That is, as shown in FIG.
Is located forward of the nozzle head 60,
The warm water spouted from the hot water spout 64a reaches the affected part 81 of the user, and the cold water spouted from the cold water spout 64b reaches the front of the affected part 81 of the user 80. When the movable body 61 moves to the rear position as shown in FIG. 5 (a), the cold water spouted from the cold water spouting hole 64b reaches the affected part 81,
The hot water spouted from the hot water spouting hole 64a reaches the rear of the affected part 81. Therefore, as the movable body 61 reciprocates repeatedly, hot water and cold water hit the affected part 81 alternately.

The interval between the hot water and the cold water and the time during which each of the cleaning waters hit the affected part 81 are determined by the reciprocating cycle of the movable body 61 and the operation pattern within one cycle. Generally, the movement of the human body in which the blood vessel is relaxed or contracted by being warmed or cooled is not very well-followed, so that it is usually reciprocated at a considerably low frequency.

On the other hand, in view of the effect of promoting blood circulation, it is desirable that the temperature change be abrupt. Therefore, as shown in FIG. This is a state where the switching between the first temperature Th and the second temperature TL is almost stepwise. In order to realize such a state, the movable body 61 moves as fast as possible between two positions, a front position and a rear position, as shown in FIG. The control may be performed such that the vehicle is stopped at the rear position for a predetermined time. In the conventional human body local cleaning device, for example, the temperature change of the cleaning water reaching a predetermined local portion is as shown in FIG.
The change between the two temperatures was rather slow. Therefore, it was difficult to obtain a sufficient blood circulation promoting effect,
According to the present embodiment, since the temperature is rapidly switched, a high blood circulation promoting effect can be obtained.

In FIG. 6A, the high-temperature period and the low-temperature period are substantially the same, but they do not need to be the same, and can be changed as needed. For example,
FIG. 6B shows an example in which the high-temperature period is longer than the low-temperature period. It is clear that such adjustment can be easily achieved by controlling the movement of the movable body 61.

When the movable body 61 is reciprocated linearly as described above, there are a portion where only hot water is intermittently hit and a portion where only cold water is hit intermittently before and after the diseased part 81 is sandwiched. In particular, when only cold water is applied intermittently, not only may the user have discomfort, but also the blood vessels may contract, which may have an adverse effect on promoting blood circulation. Therefore, by controlling the discharge of the cleaning water in synchronization with the movement control of the movable body 61, it is possible to eliminate or reduce a portion to which only the cold water or the hot water is applied.

An example of such control will be described.
FIG. 7 is a diagram schematically illustrating a range where warm water reaches and a range where cold water reaches when the movable body 61 reciprocates in the human body. In the area B where the two overlap, hot water and cold water alternately hit with time. On the other hand, in the area A, only the hot water hits when the movable body 61 reaches the vicinity of the rear position, and neither the cold water nor the hot water hits in other periods. Conversely, in the area C, only the cold water hits when the movable body 61 reaches the vicinity of the front position, and neither the cold water nor the hot water hits in the other period.

The control unit 70 determines that the movable body 61 is in the position shown in FIG.
The driving current flowing through the electromagnetic coil 67 is controlled so as to repeatedly reciprocate between the front position and the rear position as shown in FIG. Also, in synchronization with the control of the movable body 61, the first on-off valve 31 is turned on / off as shown in FIG. 8B, and the chilled water on-off valve 33 is turned on as shown in FIG. 8C. On / off control. That is, the movable body 61 is located at a position where the hot water discharged from the hot water spouting hole 64a reaches the region A.
Is present, the first on-off valve 31 is turned off, and the discharge of the hot water from the hot water discharge hole 64a is temporarily stopped. Therefore, at this time, only the cold water discharged from the cold water discharge hole 64b hits the buttocks of the user. In addition, cold water spouting hole 64b
When the movable body 61 is at a position where the cold water discharged from the tank reaches the region C, the cold water on-off valve 33 is turned off, and the discharge of the cold water from the cold water discharge hole 64b is temporarily stopped.
Therefore, at this time, only the warm water discharged from the warm water spouting hole 64a hits the buttocks of the user. Accordingly, there is no portion to which only the hot water or only the cold water is applied, and the region to which the cleaning water is applied is always alternately applied with the cold water and the hot water.

In the above embodiment, the movable body 61 is reciprocated in the front-rear direction. However, the movable body 61 may be reciprocated in the horizontal direction. In addition, it is possible to control so as to draw an appropriate trajectory, such as a rotary motion, instead of a linear reciprocating motion.
It is convenient that these trajectories can be selected by the user by operating the operation panel or the remote controller.

When only the reciprocating motion is performed, it is not necessary to arrange the electromagnetic coil 67 in a ring shape. That is, for example, an electromagnetic coil is provided at one location in the circumferential direction, and the ferromagnetic material is disposed on the movable body with the air gap interposed therebetween with respect to the electromagnetic coil. Further, a spring is provided on the side opposite to the electromagnetic coil with respect to the axis C, and the movable body is urged in the direction of the electromagnetic coil by the spring. When a drive current is applied to the electromagnetic coil, a repulsive force is generated between the electromagnetic coil and the ferromagnetic body, and the movable body moves in a direction opposite to the electromagnetic coil across the shaft against the urging force of the spring. Further, when the power supply to the electromagnetic coil is stopped, the movable body moves in a direction approaching the electromagnetic coil by the urging force of the spring. As a result, the movable body reciprocates along a predetermined linear trajectory.

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

The number of water discharge holes is not limited to one each,
A plurality can be provided. However, the hot water spouting from the hot water spouting hole and the cold water spouting out from the cold water spouting hole may overlap at a position separated by a predetermined distance (normally, the separation distance from the water spouting hole when the user is seated on the toilet seat to the human body local part). It is necessary to avoid this.

The number of nozzles is not always one, and for example, a configuration may be adopted in which a nozzle for hot water and a nozzle for cold water are separately provided. However, in terms of cost,
It is practical to provide a hot water discharge hole and a cold water discharge hole in one nozzle, and this does not reduce the effect at all.

Further, the above-described water discharge section driving mechanism is merely an example of a means for controlling the cleaning water discharged from the water discharge hole so as to draw a predetermined trajectory, and the same action can be achieved by various methods.

For example, a moving water passage provided on the movable body and an immovable water passage provided on the nozzle body side are indirectly connected,
A motor for rotating the movable body about an axis is provided. Then, while the movable body is rotated by the motor, the hot water and the cold water supplied from the immovable water passage to the movable water passage are jetted from the hot water discharge hole and the cold water discharge hole, respectively, so that the discharge is performed in 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.

As described above, since the nozzle body 44 is movable at least in the front-back direction by the nozzle driving unit 50, the nozzle body 44 is moved forward and backward while discharging hot and cold water by using this. Wash water that reaches a predetermined local area by reciprocating may be replaced with hot water and cold water.

Further, the direction of the cleaning water jetted from the water discharge hole may be periodically switched using a fluid oscillation element utilizing the so-called Coanda effect (fluid adhesion effect). In this case, since the switching cycle of the discharge direction of the cleaning water depends on the flow rate of the cleaning water, the flow rate may be determined according to the replacement cycle of the hot water and the cold water.

In addition, the predetermined trajectory water discharge control means can perform various modifications. Regarding the configuration of such means and the details of its operation, the applicant of the present invention has disclosed the above-mentioned Japanese Patent Application No. 11-1.
It has already been proposed in 69767 and the like.

In the above embodiment, the cooling unit is used to obtain the cold water. However, if the temperature of the washing water supplied from the water tap or the water storage tank is sufficiently low,
Without providing a cooling unit, the washing water that has not been heated may be simply sent out to the cold water flow path.
However, in general, for example, the water temperature of the original washing water itself often becomes high under the influence of the ambient temperature in the summer or the like. Is preferred.
