Abstract

PROBLEM TO BE SOLVED: To effectively accelerate defecation for preventing and curing constipa tion. SOLUTION: When a defecation accelerating key is pressed, a discharge hole 36 is periodically moved by an actuator built in a nozzle head so as to let a predetermined locus be drawn by the washing water, in this way, the washing water is controlled to alternately stimulate user's anal region 81 of the breech 80 and the whole of circumanal region 82 surrounding the anal region 81. By moving the discharge hole 36 at a high speed by the actuator, the whole of the circumanal region 82 can be stimulated softly as if covered with a small amount of water, so that anal can be quickly relaxed effectively. When concentrating water to the anal region 81, the discharge is increased or the velocity is made higher, and water pressure at the time of reaching the anal is controlled to become higher than inner pressure of the anal. In this way, water can effectively enter into the relaxed anal and the user can have a call of nature.

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 As constipation is said to be "the cause of all illnesses", it can cause diseases of various organs such as the rectum, large intestine, small intestine, liver, gallbladder, and heart. In addition, it is not good for beauty, and may cause pimples and acne. Therefore,
In order to promote defecation to eliminate constipation, a method using a drug such as a laxative or an enema is widely used. However, depending on these drugs, the body may acclimate to the drugs, and constipation may become chronic, making it more difficult to defecate on its own. In other words, constipation may be worsened.

On the other hand, as one of the methods of promoting defecation without using a medicine, there is a method of obtaining an effect similar to that of an enema using a human body local cleaning device. In general, enema means that a liquid such as a drug (mainly glycerin solution) is injected into the rectum or large intestine from the anus to directly stimulate these intestinal tract walls. In this case, the washing water (drugs can be mixed if necessary) is put into the anus. Enema has two main effects. One is to stimulate the intestinal tract to enhance intestinal peristalsis, which results in increased rectal pressure and feces. The other is to soften and lubricate hard stool in the intestinal tract by osmosis, and as a result, stool is easily discharged smoothly.

In order to obtain the above-mentioned enema effect by a conventional human body cleaning device, a device integrated with a nozzle is brought into contact with the anus or inserted into the anus to spray cleaning water (hereinafter referred to as "contact method"). ) Or intended to put some of the cleaning water into the anus rather than intensively discharging water from the nozzle near the anus (hereinafter referred to as the “concentrated water discharging method”).
There is). Among them, the contact method is unsanitary because it contacts the anus, and it is necessary to replace or clean the contact portion of the nozzle each time it is used. Also, since a hard object comes into contact with the anus, an inexperienced person not only feels uncomfortable, but also has difficulty in properly inserting it into the anus. Therefore, in order to be easily used by ordinary people, a human body local cleaning apparatus using the concentrated spouting method is more preferable.

[0005] For example, Japanese Patent Application Laid-Open No. H11-32070 describes a device for cleaning a local part of a human body by a concentrated water spouting method. In this apparatus, two types of ejections are periodically repeated: a relaxation-promoting jet, which is a shower-like water flow with a weak water force, and an anal infiltration jet, which is a thin water flow with a strong water force. As a result, the anal infiltration jet intensively hits the anus whose tension has been released by the relaxation accelerating jet, so that the washing water easily leaks into the anus and a high defecation-inducing effect can be obtained.

[0006]

Various methods can be considered to promote the relaxation of the anus. In the above-mentioned conventional body part cleaning apparatus, for example, the nozzle is configured to be movable back and forth and left and right by a motor. The nozzle is moved so that the cleaning water hits the outer periphery of the anus in an arc shape. However, in such a conventional configuration, there is a limit to the moving speed of the nozzle. That is, since the moving speed cannot be made too high, the region surrounding the user's anus is sequentially stimulated. In such a relatively low-speed movement, the user can easily perceive the site where the washing water has arrived, and depending on the person, the user may get nervous. Therefore, there is a problem that the effect of relaxing the anus becomes thin, and even if the washing water is sprayed toward the anus, the water does not always sufficiently enter the anus and an effective enema cannot be performed. In order to more reliably and effectively relax the anus, it is effective to gently stimulate the anus so as to wrap around the entire anus.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and an object of the present invention is to provide a human body local cleaning apparatus capable of obtaining a more reliable and high defecation promoting effect. is there.

[0008]

According to the present invention, there is provided an apparatus for cleaning a local part of a human body according to the present invention, in which cleaning water reaches a local part of a user sitting on a toilet seat to clean the local part. A) a nozzle having a spout for discharging the washing water; b) a spout driving means for driving a part of the nozzle including the spout; and c) washing discharged from the spout. The spout drive means such that the wash water from the spout draws a predetermined trajectory so as to alternately perform an anal relaxation promotion period in which water reaches the anal periphery and a wash water intrusion period in which the water reaches the anal portion. And d) water pressure control means for controlling the flow rate and / or flow rate of the washing water so that the water pressure at the time when the washing water collides with the anus is higher than the pressure in the anus. It is characterized by.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the apparatus for cleaning a human body part according to the present invention, the water outlet drive means is controlled by the predetermined trajectory water discharge control means so that the wash water discharged from the water outlet during the anal relaxation relaxation period. Reaches the periphery of the anus, avoiding the anus. On the other hand, during the cleaning water infiltration period, the cleaning water discharged from the water outlet intensively reaches the anus. In addition, the flow rate and flow rate of the washing water are increased by the water pressure control means during the washing water infiltration period, and the water pressure at the time of hitting the anus is set to be higher than the pressure in the anus. In this way, strong stimulating flush water is applied to the anus that has been sufficiently relaxed by being softly stimulated to wrap the anus during the anal relaxation promotion period, so that water easily enters the anus and effectively. It can stimulate the inside of the anus to make you feel good.

In addition, the anus cannot continue to relax or contract, and in general, relaxation and contraction are alternately repeated at a predetermined cycle, and the pressure in the anus varies accordingly. Therefore, in the human body local cleaning device according to the present invention, the predetermined trajectory water discharge control means and the water pressure control means each have a predetermined trajectory, and a flow velocity and / or a flow velocity so as to be substantially synchronized with an anal pressure fluctuation due to relaxation and contraction of the anus. By controlling the flow rate, the washing water can be more effectively penetrated into the anus.

In one embodiment of the above-mentioned water outlet driving means, at least the water outlet can be configured to move along a predetermined trajectory around an axis inside the nozzle with respect to the nozzle. According to this configuration, since the moving portion is smaller than when the entire nozzle is moved along a predetermined locus as in the conventional device, 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, a wide area can be softly stimulated with a small amount of water.

[0012] In the above structure, the water outlet driving means may include:
It may be configured to 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 water outlet driving means includes an armature for forming a magnetic field that changes with time in a predetermined closed space;
A movable element that is arranged in the magnetic field and interacts with the magnetic field to move in the predetermined closed space along a predetermined trajectory, and the movable element is provided with the water outlet. . 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 range of the reaching position of the cleaning water and its shape is very large.

Further, the predetermined trajectory water discharge control means includes:
The water outlet driving means may be controlled so that the speed at which the trajectory is drawn is not constant within one cycle. That is, for example, if the above-mentioned speed is reduced or the movement is temporarily stopped at the timing when the washing water reaches the part particularly effective in promoting the anal relaxation in the peripheral part of the anus, the part is effectively stimulated. And a high anal relaxation effect can be obtained.

Further, the predetermined trajectory water discharge control means includes:
By changing the frequency of movement of the water outlet, the area of the reach of the water discharge can be changed. When the moving frequency of the water outlet, that is, the moving speed changes, the area of the washing water that is applied by the cleaning water changes depending on the configuration of the water outlet driving means. For example, as described above, when the water outlet is provided in the movable element and the movable element is movably restrained by an elastic body, the movable element has a natural frequency. Therefore, when the laser beam is moved at a frequency near the natural frequency, the moving range is further widened by the resonance action, and the cleaning area is relatively widened. By changing the washing area in this manner, not only water is alternately discharged from the anus to the periphery of the anus but also to the anus, and the washing area can be appropriately adjusted according to the user's personal preference and physical condition. In addition, if the washing area is changed during spouting, various parts can be stimulated without monotonous washing.

Further, the apparatus for cleaning a local part of the human body according to the present invention may further include an intermittent water discharge control means for intermittently discharging the water for cleaning. Further, it is preferable that the intermittent water discharge control means be configured to change the intermittent cycle of the washing water. In intermittent water discharge, if the intermittent cycle is lengthened, the user can easily perceive the discontinuity of the water mass, and feels a strong stimulus even at the same discharge pressure. Conversely, when the intermittent cycle is shortened, the user cannot perceive the discontinuity of the water mass, but recognizes that the washing water is continuously applied, and the feeling of irritation is weakened. Therefore, the intensity of the stimulus can be temporally varied by appropriately varying the intermittent period.
Further, according to such intermittent water discharge, even when the flow rate of the wash water is increased, the discharge flow rate during a predetermined time can be reduced according to the wash water discharge time or the wash water discharge amount in one intermittent cycle period. It is also effective in saving water.

The water outlet may be composed of a single water outlet, or may be an aggregate of a plurality of water outlets for simultaneously discharging cleaning water.

[0018]

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 centered on a water flow path of a human body local cleaning apparatus 10 according to the present embodiment.

A connecting pipe 10 connected to an external water tap, which is a water supply source, is connected to a water inlet 11a of a valve unit 11 including a pressure reducing valve 12, a solenoid valve 13, and a safety valve 14. The pressure reducing valve 12 reduces the pressure of the water flowing through the connecting pipe 10 to a predetermined pressure (generally, a discharge pressure suitable for cleaning a human body part after stool). This pressure can be adjusted appropriately.

The water outlet 11b of the valve unit 11 is connected to the heater 1 while detecting the supplied water by the temperature sensor 18.
7 is connected to a water inlet 15a of a heating unit 15 including a heat exchanger 16 for heating to a predetermined temperature. The water outlet 15b of the heating unit 15 is connected to a water inlet 19a of a flow control unit 19 including a check valve (vacuum breaker) 20 and a flow control valve 21 driven by a flow control motor 22. The check valve 20 opens the pipe to the atmosphere, thereby preventing the backflow of the washing water from the nozzle body 31 described later. The flow control valve 21 adjusts the degree of opening of the pipeline, and sends out flush water at a flow rate corresponding to the degree of opening. That is, the supply / stop of the washing water to the nozzle body 31 is executed by opening and closing the uppermost electromagnetic valve 13, and the flow rate is adjusted by the flow regulating valve 21. The water outlet 19b of the flow control unit 19 is
4 is connected to the water inlet of the water supply pump 27.

Bubble mixing unit 2 including bubble mixing unit 24
3 performs the function of mixing air bubbles into the cleaning water. That is, in the apparatus of the present embodiment, the air pressurized by the air pump 25 is sent to the bubble mixing section 24 via the air flow regulating valve 26, so that bubbles can be mixed into the cleaning water at a predetermined ratio. .

FIG. 2 is a schematic sectional view of the bubble mixing section 24. As shown in FIG. In the figure, the washing water flows from left to right.
An air chamber 242 communicating with the air introduction pipe 243 is formed inside the housing 241, and a cylindrical shape is formed on the inner peripheral side of the air chamber 242 so that the washing water flows through the inside of the washing water conduit continuously. A bubble dispersion 244 is provided. Bubble dispersion 24
Numeral 4 is a porous body having a large number of minute openings. 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.

After 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.

Returning to FIG. 1, the description will be continued.
7 is connected to two switching valves 28, one of the switching valves 28 is connected to the anal cleaning water inlet 32 of the nozzle unit 30, and the other water outlet is connected to the bidet cleaning water inlet 3.
3 is connected. The water supply pump 27 includes a reciprocating plunger, and imparts a temporal density to the flow of the wash water sent from the water outlet, as described later. Nozzle unit 3
0 comprises a nozzle body 31 and a nozzle driving unit 38,
The nozzle body 31 can be extended and retracted by a nozzle driving unit 38. Inside the nozzle body 31, an anal washing water passage 34 and a bidet washing water passage 35 are independently provided, and the inlets of these water passages are an anal washing water inlet 32 and a bidet washing water inlet 33. is there. That is, the switching valve 2
8 has a function of switching the supply destination of the washing water to the anal washing water passage 34 and the bidet washing water passage 35.

FIG. 3 is a configuration diagram of the nozzle unit 30. The nozzle unit 30 includes a nozzle drive motor 381 (not shown in FIG. 3) which is a part of the nozzle drive unit 38.
And a driven pulley 41 and two driven pulleys 42 and 43. The three pulleys 41, 42, and 43 have a timing belt (hereinafter, referred to as a timing belt) having an inner peripheral surface formed in a saw-tooth shape. Simply called "belt") 44
Are wound around with an appropriate tension 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.
In addition, the latch 4 provided on the side of the nozzle holder 48.
9 holds 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 381, the belt 4 is moved between the driven pulleys 42 and 43.
4 moves obliquely forward and downward with the nozzle holder 48, 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 anal cleaning position or the bidet cleaning position in front of the anal cleaning position, or conversely, is retracted from those cleaning positions to the original standby position.

The nozzle head 46 has an anal washing water passage 3
An anal spouting hole 36 and a bidet spouting hole 37 are provided in communication with the bidet washing water passage 4 and the bidet washing water passage 35, respectively. Each of the water discharge holes 36 and 37 is provided with a water discharge port driving means and a predetermined trajectory water discharge control means for controlling the cleaning water discharged from the holes to draw a predetermined trajectory. In this embodiment, the water outlet driving means has, 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. Actuator.

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 anal water discharge hole 36 is described, and the description of the components related to bidet cleaning is omitted, but the bidet water discharge hole 37 is similar or similar to this. Water discharge port driving means having the above configuration.

In FIG. 4, the movable body 60 having a substantially cylindrical shape has a moving water passage 62 inside, and an upper opening of the moving water passage 62 is an anal water discharge hole 36. Mobile waterway 62
Is connected to an anal washing water passage 34 provided inside the nozzle body 31 by a stretchable joint pipe 63 such as a rubber pipe or a bellows-shaped pipe. Are now available. An annular ferromagnetic body 61 is provided integrally on the outer peripheral side of the movable body 60,
An annular electromagnetic coil 65 is provided on the outside thereof with a gap 64 therebetween.
Are arranged. The electromagnetic coil 65 is connected to the nozzle head 46
Since it is buried inside, it is not flooded, 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 anal water discharge hole 3 is controlled.
6 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 view showing an example of the trajectory of the washing water discharged from the anal water discharge hole 36. For example, if the cleaning water is discharged from the anal water discharging hole 36 while controlling the power supply to the electromagnetic coil 65 so that the anal water discharging hole 36 rotates in a spiral shape, the cleaning water is moved with the movement of the water discharging hole 36. 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, since the spouted water is swirled in a so-called spiral manner in the spout driving means, the spouted water impinges on a part of a predetermined cleaning area 71 when viewed instantaneously. Therefore, the cleaning 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 water pump 27 will be described. The main function of the water supply pump 27 is, as described above, to impart a density to the flow of the wash water discharged from the water discharge holes 36 and 37 by appropriately controlling the speed and cycle of the reciprocation of the plunger. It is in. FIG. 6 is a diagram schematically showing the water discharge state at this time, and FIG.
(B) is an example in which the discharged washing water has a pulsation, that is, the flow rate fluctuates with time. In the case of (b), it is not strictly said that the discharge is intermittent, but here, such pulsating discharge is also referred to as intermittent discharge.

In such an intermittent water discharge, when the intermittent frequency is increased, the user cannot sense the contact of the discontinuous water mass or the fluctuation of the flow rate, and it is as if the washing water of a 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.

FIG. 7 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 50 configured using a microcomputer or the like is installed. The control unit 50 includes a plurality of operations such as an anal cleaning key 52a, a bidet cleaning key 52b, a defecation promotion key 52c, and a stop key 52d. A key input signal is input from an operation panel 52 having keys, a seating detection signal is input from a seating sensor 53 provided on the toilet seat, and a water temperature detection signal is input from the temperature sensor 18. The control unit 50 receives these input signals, performs predetermined processing, and performs, via the load driving unit 51, the electromagnetic valve 13, the heater 17, the flow control motor 22, the air pump 25, and the air flow control valve 2.
6. Water pump 27, switching valve 28, nozzle drive motor 3
81, the electromagnetic coil 65 is appropriately controlled.

In the apparatus for cleaning a local part of the human body according to the present embodiment, when the user operates the defecation promoting key 52c of the operation panel 52 in a state where the user is sitting on the toilet seat, a special control for positively promoting the user's defecation is provided. Is executed. Next, the operation of facilitating defecation in this human body local cleaning apparatus will be described in detail.

When the human body cleaning device is not in use, the nozzle body 31 is retracted to the rearmost position, thereby preventing the nozzle body 31 from obstructing 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 the defecation facilitation key 52c on the operation panel 52 after sitting, the control unit 50 receives the key input signal and sets the switching valve so that the washing water flows into the anal washing water passage 34 first. 28 flow paths are set. Further, the control unit 50 appropriately energizes the nozzle drive motor 381 with a predetermined polarity, and rotates the drive pulley 41 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 driving pulley 41 rotates by a predetermined angle, the nozzle head 46 reaches a washing position where washing water discharged from a human body part, specifically, the anal water discharge hole 36 reaches near the anus.

When the nozzle head 46 reaches the predetermined cleaning position, the control unit 50 drives the flow control motor 22 to appropriately set the opening of the flow control valve 21 and opens the air flow control valve 26. The degree is also set appropriately, and the solenoid valve 13 of the valve unit 11 is opened. Then, water flows into the heat exchanger 16, and the hot water that is pushed by the water and already stored in the heat exchanger 16 passes through the flow control unit 19, the bubble mixing section 24, the water pump 27, and is switched by the switching valve 28. It is delivered to the anal irrigation channel 34. Then, the washing water is discharged from the anal water discharge hole 36.

FIG. 8 is a schematic diagram showing the relationship between the user's buttocks 80 and the arrival position of the washing water. After the discharge of the washing water is started, the control unit 50 alternately supplies water to the anus 81 of the buttocks 80 and the anal peripheral part 82 surrounding the anus 81 at a predetermined cycle, as shown in FIG. The electromagnetic coil 65 is controlled so as to reach. In other words, control such that the anal water discharge hole 36 is stationary or moves in a very narrow range at substantially the center of the movable range (that is, on the axis C) (see FIG. 8A), and the anal water discharge hole 36 is In addition, control such that the distance from the axis C changes while changing in a predetermined range (see FIG. 8B) is alternately performed. When the movable body 60 is moved by applying a rectangular wave DC voltage (current) to each of the plurality of electromagnetic coils 65, for example, by changing the magnitude of the applied voltage (current), the area that the water discharge reaches,
That is, the cleaning area can be changed. Further, the cleaning area can be changed by changing the ON time (that is, the duty ratio) of the applied voltage. Here, it is preferable that the above-mentioned predetermined cycle is set in accordance with the rhythm of the human body in which the anus relaxes and contracts.

Further, when the washing water reaches the peripheral part 82 of the anus, the moving speed of the movable body 60, that is, the anal water discharge hole 36 may be increased. As described above, when the moving speed is low, it is easy to perceive the intermittent contact of water with each part due to the moving, so that the user feels the stimulation by the water relatively strongly. On the other hand, if the moving speed is increased to a certain extent, it is impossible to perceive a period during which water is not applied to each part in spite of being temporally intermittently applied with water. Perceives that water is continuously hitting, and the relative stimulus is relieved. Even when stimulating the peripheral part 82 of the anus, if the stimulus is locally felt, the anus may be rather tense depending on the user, but in this device, the washing water moves at a high speed. While stimulating the anal periphery 82, it is gently stimulated to wrap around the anus, and the anus can be relaxed more effectively. Further, as described above, if bubbles are mixed in the cleaning water, the irritating feeling is weakened, so that bubbles may be mixed in an appropriate ratio.

Further, it is preferable that the position at which the washing water reaches is changed and the flow velocity is also changed. That is, the water pressure when the water discharged from the anal water discharge hole 36 reaches the local part of the human body depends on the washing water density and the flow velocity immediately before the water reaches.
Even when water is discharged toward the anus 81 while the anus 81 is relaxed, if the water pressure at that time is smaller than the pressure in the anus, it is difficult for water to enter the anus. Therefore, the delivery pressure of the water supply pump 27 is increased at the timing when the water is discharged to the anus 81. Further, the flow rate may be increased by increasing the opening degree of the flow regulating valve 21.

After the anus has sufficiently relaxed,
Due to the intensive discharge of water to the anus, water effectively penetrates into the anus, and the water stimulates the inner wall of the anal canal or rectum to promote the instinct. Therefore, a high effect of promoting bowel movements can be obtained.

Instead of or in addition to changing the arrival position of the washing water due to the movement of the anal water discharging hole 36 as described above, the period of the intermittent water discharging may be changed by appropriately controlling the water supply pump 27. . As described above, if the cycle of intermittent water discharge is lengthened (if the frequency is lowered), a relatively strong stimulus can be given to the cleaning water arrival site. Conversely, when the cycle of intermittent water discharge is shortened (when the frequency is increased), the stimulus given to the washing water arrival site can be reduced. In other words, if the period of intermittent water discharge is changed, the sense of irritation also fluctuates, and it is possible to promote relaxation of the anus, and by discharging water toward the anus at a relatively high water pressure after relaxing in such a manner. Water can effectively penetrate into the anus.

In the above embodiment, the control of changing the frequency of the voltage applied to the electromagnetic coil 65 for moving the movable body 60 can be performed to change the cleaning area. When the frequency of the voltage applied to the electromagnetic coil 65 is changed, the movable body 60,
6, the moving speed (that is, the moving frequency) changes. The influence of the change in the moving frequency on the cleaning area has several factors as follows.

First, there is an influence of the natural frequency. As shown in FIG. 4A, since the movable body 60 is connected to the nozzle head 46 via the joint pipe 63 made of an elastic body, the movable body 60 is restricted by the joint pipe 63 when the movable body 60 moves. . The movable body 60 has a natural frequency depending on its size and weight, and when a force acts at a frequency near the frequency, a large vibration is generated by resonance. Therefore, when the frequency of the voltage applied to the electromagnetic coil 65 is appropriately adjusted to make the moving frequency of the movable body 60 close to the natural frequency, the movable body 60 itself largely rotates or swings due to resonance, and the cleaning area becomes large. .

The second is the action of the force generated by the movement. Overall, the cleaning area tends to increase with increasing frequency up to a certain extent. This is based on the following principle. Considering the direction in which the washing water is spouted from the spouting hole, first, when the spouting is performed in a state where the spout does not draw a predetermined trajectory, that is, in a state where the spouting hole and the nozzle itself are stationary, as shown in FIG. The water discharge direction is water discharge hole 3
6 depends only on the vertical velocity component (M1 component). When water is discharged so as to draw a predetermined trajectory, that is, when the water discharge hole 36 rotates or swings, as shown in FIG. 9B, the water discharge direction is determined by the movement of the water discharge hole 36 in addition to the M1 component. It is determined as a combination of three directions of a horizontal speed component (M2 component) along the trajectory and a speed component (M3 component) due to a force against acceleration generated when the direction of the movement trajectory of the water discharge hole 36 is changed. That is, when the water discharge follows a predetermined trajectory, the water discharge direction is M1 compared to when the predetermined trajectory is not drawn.
The component and the M2 component are added. At this time, the influence of the M2 component and the M3 component is different depending on the magnitude of the moving frequency of the water discharge hole 36, and as a result, the cleaning area is different.

When the moving frequency is increased, as shown in FIG. 9D, both the M2 component and the M3 component are greatly added,
As a result, as shown in FIG. 9C, the water discharge direction is greatly inclined to the outer peripheral side, and the cleaning area is increased. Conversely, when the moving frequency is lowered, as shown in FIG.
The degree of addition of the three components is small, and as shown in FIG. 9E, the cleaning area is larger than when the predetermined trajectory is not drawn, but the cleaning area is smaller than when the moving frequency is high as described above. . As described above, the cleaning area can be varied depending on the level of the moving frequency, separately from the above-described resonance. However, the moving speed of the movable body 60 is limited, and if the frequency of the voltage applied to the electromagnetic coil 65 is too high, the movable body 60 cannot follow. In that case, the movable body 60 stays near the central axis C, and the cleaning area is reduced.

As described above, although a plurality of factors contribute to the relationship between the moving frequency of the water discharge hole and the cleaning area, the reproducibility is extremely high. , That is, the cleaning area can be varied by the frequency of the voltage applied to the electromagnetic coil 65.

Next, an example of a modification of the structure of the actuator shown in FIG. 4 will be described. FIG. 10 is a diagram showing the configuration of this actuator, where (a) is a schematic sectional view,
(B) is a top perspective view. In this actuator, the movable body 90 includes a flange portion 91 fixed to the upper surface of the cover 46a of the nozzle head 46,
A water discharge piece 93 fitted with a central through hole of the cylindrical part 92 and having an anal water discharge hole 36 at the center thereof; And a magnetic actuating body 94 which is widely extended. The flange portion 91 and the cylindrical portion 92 are integrally molded products made of an elastic material having a deformation restoring property such as rubber and estramer. The water discharge piece 93 is a resin molded product, and the lower end side of the anal water discharge hole 36 is formed in a large-diameter water discharge guide hole 36a. Since the movable body 90 is fixed to the cover 46 a at the periphery of the flange portion 91, it is suspended by the flange portion 91, and can be swung in each direction by deforming and restoring the connecting portion between the flange portion 91 and the cylindrical portion 92. It has become.

Below the movable body 90, the anal washing water passage 3
A protruding portion 95 having an in-head anal water discharge hole 34 a communicating with the movable member 4 at substantially the center is formed with an appropriate gap between the protrusion and the lower surface of the movable body 90. In addition, three electromagnetic coils 96 are circumferentially spaced apart from each other by a predetermined distance so as to surround the protrusion 95. Each of the electromagnetic coils 96 has the same configuration, and two cores (iron cores) 97 that stand upright at predetermined intervals.
a, 97b and a coil 9 wound around one core 97a
8 is provided. When the coil 98 is energized, a magnetic flux that circulates around the two cores 97 a and 97 b is generated, and the resulting magnetic field acts on the magnetic operating body 94 of the movable body 90.

When a magnetic attraction force acts on the magnetic body 94, the magnetic body 94 moves downward, and the movable body 90, that is, the water discharge hole 36, is moved to the magnetic body 94.
Tilts according to the downward movement of the. Then, for example, if the respective electromagnetic coils 96 are sequentially energized in a counterclockwise or clockwise direction to be excited, the magnetic action bodies 94 sucked downward also move sequentially, and accordingly, the anal water discharge holes 36 are also sequentially tilted. It moves three-dimensionally clockwise or clockwise. The swing angle α of the anal water discharge hole 36 is adjusted by adjusting the strength of the suction force, that is, the voltage value (current value) of the energizing voltage to the electromagnetic coil 96 (strictly, the coil 98) and the duty ratio of the energizing voltage. Control is possible. Further, since the movable body 90 is supported by the flange portion 91 which is an elastic body and has a natural frequency, the swing angle α can be controlled by controlling the frequency of the energized voltage of the electromagnetic coil 96 as described above. .

In the above configuration, when the washing water is supplied to the anal washing water passage 34, water is jetted from the anal water discharging hole 34a in the head, and the water is discharged from the anal water discharging hole 36 through the water discharging guide hole 36a of the movable body 60. Is done. Since the area of the upper and lower openings sandwiching the gap at the lower end of the movable body 60 is large on the upper side, when the cleaning water passes through this gap, the surrounding air is entrained and discharged in a state containing bubbles. Therefore, bubbles can be included at an appropriate ratio without providing the bubble mixing unit as described above. By controlling the energization of the three electromagnetic coils 96 as described above while performing such water discharging, the cleaning water can reach a wide area by tilting the anal water discharging hole 36. Also, by appropriately controlling the voltage value of the energizing voltage, the duty ratio of the energizing voltage, or the frequency, etc.,
By varying the swing angle α of the anal water discharge hole 36, as a result, water discharge with a narrow cleaning area that intensively applies the cleaning water to the anus and water discharge that widely applies the cleaning water around the anus are alternately performed. Can be done.

The water outlet driving means may employ various methods other than the above. 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, in the apparatus for cleaning a local part of the human body according to the present invention, the switching pattern of the cleaning area can be appropriately set irrespective of the configuration of the water outlet driving means and the predetermined trajectory water discharging control means. FIG. 11 is an example showing this switching pattern, and FIG. 11 (a) shows the switching between the large cleaning area (ie, water discharge around the anus) and the small cleaning area (intensive water discharge to the anus) for a very short time. (That is, instantaneously). On the other hand, FIG. 11B shows that the washing area is gradually enlarged when the washing area is switched from small to large, and when the area is enlarged to a predetermined area, the washing area is suddenly reduced and water is concentrated on the anus. It is intended to be. There can be various switching patterns including such two patterns. Although which pattern is particularly effective in promoting defecation varies from individual to individual, according to a monitor survey conducted by the present inventors, FIG.
The effect of the pattern (b) seems to be particularly large. This is because the anus is gradually relaxed by gradually increasing the washing area, and the water is concentrated on the anus instantaneously (that is, in an unexpected state) in a fully relaxed state, and more water is discharged. It is considered that this is because the washing water efficiently penetrates into the anus.

In the above embodiment, the water outlet driving means rotates the water outlet about the axis C, but the mode of movement of the water outlet is not limited to this. For example, as in the example of FIG. 10, 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 is arranged so as to sandwich the movable body. By appropriately controlling the excitation of two or one electromagnetic coil arranged on one side, the inclination of the movable body is controlled, whereby the direction of jetting of water discharged from the water discharge port is changed, and the washing water is changed. A predetermined locus may be drawn. 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.

When the anus is relaxed, it is not necessary to stimulate the central part of the anus intensively. Therefore, the water discharge is temporarily (that is, compared with the water discharge time when the water is intensively discharged at the central part of the anus). Even if the predetermined trajectory of the water discharge is set so as to pass through the anal center, the intended effect of the present invention can be achieved. That is,
Such a water discharge pattern is also included in the present invention.

The above-described 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. For example, in the above embodiment, the number of the anal water discharge holes 36 used for facilitating defecation is one, but an aggregate of a plurality of water discharge holes provided in the movable water passage 62 may be used.
