DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a local part of a human body capable of positively inducing user's convenience and prompting defecation.

[0002]

2. Description of the Related Art FIG. 15 is a structural view of a water channel of a conventional hot water cleaning apparatus using a human body local cleaning apparatus of this type, and FIG. 16 is a sectional view of a cleaning nozzle used here. In FIG. 1, reference numeral 1 denotes a cleaning nozzle having a jet port 2 and reference numeral 3 denotes a hot water tank for heating and storing cleaning water, in which a heater 4 is provided. Reference numeral 5 denotes a water pump for supplying cleaning water, and reference numeral 6 denotes a main solenoid valve. The cleaning nozzle 1 is provided in the throttle unit 7, the adhering walls 8, 9 provided on both sides of the jet port 2, and a pair of vortex chambers 10, 11 provided on both sides in the outflow direction of the jet and the vortex chambers 10, 11. It has suction pores 12 and 13 and constitutes a fluid oscillation element type cleaning nozzle 1.

[0003] In this configuration, when hot water from the hot water tank 3 flows into the washing nozzle 1, the flow velocity is increased by passing through the throttle section 7, and the hot water is attached to, for example, the adhesion wall 8 side by the Coanda effect (fluid adhesion effect). , In the direction of arrow A. At this time, the washing water flows into the vortex chamber 10, and the vortex is generated, so that the air is sucked from the intake pores 12, and the pressure in the vortex chamber 10 increases. This pressure acts to move the water flow to the adhering wall 9 side, and the jet flow moves to the arrow B side. By repeating these operations, a self-oscillation state is established, and cleaning is performed while the jet stream swings. The water flow oscillates as described above to improve the cleaning power, and at the time of cleaning, a rhythmic pressure stimulus is applied to the anus to induce anal reflex.

[0004]

In order to make the user feel good by using the washing water of the human body cleaning device, the defecation reflex is induced by physically stimulating the anus with the flushing water that spouts vigorously. There is a method of stimulating the receptive organs present in the anus of the human body by leaking the washing water into the anus, and also inducing a defecation reflex. The former has been confirmed in animal studies, in which large contractions occur in the colon by mechanical anal stimulation of decerebrate dogs and spinal cord injured dogs. Also, the latter is a state of diarrhea,
Alternatively, the condition immediately after the injection of the enema solution is simulated by the leaked washing water, and in this condition, a strong defecation is caused and the involuntary internal anal sphincter is relaxed. These facts are well known in related academic societies and the like.

In view of the above, in the above-described conventional configuration, although the pressure stimulation of the washing water has a certain effect of inducing constipation, the washing water always oscillates at a predetermined cycle, so that it does not leak into the anus. It is rare, and it is not possible to induce stool by so-called enema action due to leakage of washing water into the anus. If the flow rate of the washing water is increased and the washing dynamic pressure is increased, the washing water easily leaks into the anus, but on the other hand, the bodily sensation during washing deteriorates, and in severe cases, the pain may be accompanied by even pain. Thus, there was a problem that a clear bowel movement inducing effect could not be expected.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a human body local cleaning apparatus which can be used comfortably without feeling disgust or pain and which can induce a sense of convenience very effectively.

[0007]

A jet switching means configured to be capable of switching between jets, and a controller for controlling the water supply control means and the jet flow switching means such that the relaxed jet and the infiltrating jet are periodically repeated by setting of the toilet-induced washing setting means. Is provided.

The controller properly controls the water supply control means and the jet switching means by setting the toilet inducing cleaning setting means, and periodically repeats the relaxing jet and the intruding jet to wash the human body part. Positively induces the
It is to assist comfortable defecation. In addition, since the apparatus is provided with the normal cleaning setting means and the convenience inducing cleaning setting means, it is possible to selectively use the cleaning jet in each scene, thereby improving the usability of the user.

[0010] In the human body local cleaning device according to the second aspect, in addition to the structure of the first aspect, the relationship between the jet during normal cleaning and the cleaning dynamic pressure of the relaxed jet is defined as a relaxed jet <normal jet <
It is configured as an intruding jet.

[0011] Then, the relaxing effect of the relaxing jet is further enhanced, and the infiltrating jet is easily penetrated into the anus. Furthermore, since the change in the washing dynamic pressure when switching from the relaxed jet to the intruding jet becomes large, the anus can be effectively stimulated, and the effect of inducing constipation can be enhanced.

According to a third aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the jet switching means is capable of changing the jet form of the relaxing jet and the intruding jet, as well as the relaxing jet and the intruding jet. The relationship between the cleaning area of the jet and the relaxing jet>
It is configured as an intruding jet.

[0013] The relaxing jet capable of washing a large area gives an appropriate stimulation without giving excessive stimulation to the anus, and further enhances the relaxation effect. In addition, since the intruding jet hits a small area, it easily penetrates into the anus. This can more effectively induce the user's convenience.

According to a fourth aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the controller relaxes when the incentive-induced cleaning setting means is selected and set. The jet and the immersion jet have different durations. In addition, the degree of relaxation of the anus and the degree of infiltration of the washing water greatly depend on the duration of each jet, which greatly depends on the relaxation of the anus. Improve.

The apparatus for cleaning a local part of a human body according to a fifth aspect of the present invention is configured such that, in addition to the configuration of the fourth aspect of the present invention, the duration of the relaxation jet within the repetition period is 2 seconds or more.

[0016] Then, by taking a sufficient time for the relaxing jet to stimulate the anus, anal relaxation is more reliably promoted, and the probability of water infiltration into the anus is improved.

According to a sixth aspect of the present invention, in addition to the structure of the fourth aspect of the present invention, in addition to the constitution of the fourth aspect, the duration of at least one of the relaxing jet or the intruding jet in the repetition cycle is irregularly changed. It is configured.

In addition to eliminating the monotonous feeling, the probability of infiltration of the washing water into the anus is improved by suddenly applying a penetrating jet to the relaxed anus.

According to a seventh aspect of the present invention, in addition to the configuration of the first aspect of the present invention, the controller controls the cleaning when the incentive-induced cleaning setting means is selected and set. The jet switching means is configured to control the jet switching means so that the jet at the start becomes a relaxed jet.

The present invention promotes the relaxation of the anus immediately after the start of washing, and also prevents the tension of the anus caused by suddenly hitting a strong jet.

According to the eighth aspect of the present invention, in addition to the configuration of the third aspect of the present invention, in the case where the toilet incentive cleaning setting means is selected and set, the controller sets the jet form at the start of the cleaning. The jet flow switching means is controlled so as to form a jet flow.

By releasing a relaxed jet having a small cleaning area at the start of cleaning, the user can easily position the cleaning position and improve the probability that the cleaning water leaks into the anus.

According to a ninth aspect of the present invention, in addition to the configuration of the eighth aspect, when the defecation-induced cleaning setting means is selected and set, the intruding jet immediately after the start of the cleaning is a repetition of the jet switching. In this case, the amount of water is set to be smaller than that of the intruding jet ejected after the second time.

[0024] In addition to facilitating the positioning of the user with the infiltrating jet having a small cleaning area, the tension of the anus generated at the start of the cleaning is prevented, and the relaxation of the anus is further promoted.

According to a tenth aspect of the present invention, in addition to the constitution of the first to ninth aspects of the present invention, the heating means is an instantaneous heat exchanger, and the controller is a relaxation jet. The temperature of the washing water supplied in synchronization with the switching time of the intruding jet is variably controlled.

By changing the temperature of the washing water in synchronism with the change in the stimulating pressure generated at the time of switching between the relaxing jet and the intruding jet, the feeling of irritation can be further improved and the user's convenience can be more effectively induced. .

[0027]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a view showing components of a human body local cleaning apparatus according to Embodiment 1 of the present invention.

In FIG. 1, the water supplied from the water supply pipe 14 is a water supply control means for starting and stopping the supply of the cleaning water, an original solenoid valve 15 and a water supply control means for adjusting the flow rate of the cleaning water. Variable jet strength, normal jet,
The water reaches a hot water tank 17 via a flow control valve 16 which is also a jet switching means for switching between a relaxed jet and a permeated jet. The hot water tank 17 includes a heater 18 as heating means for heating the water stored inside to an appropriate temperature, and a thermistor 19 for detecting the temperature of the hot water inside. The outlet of the hot water tank 17 is connected to a washing nozzle 21 via a hot water pipe 20, and a jet port 22 as a discharge means is formed at the tip of the washing nozzle 21.

The cleaning water is discharged from the jet port 22 by the remote controller 2.
This is done according to the instruction of 3. The remote controller 23 has a bottom switch 2 of a normal cleaning setting means for instructing a normal anal cleaning.
4. Provided are a bidet switch 25 for instructing the cleaning of the female local area, a stop switch 26 for instructing to stop the cleaning, a defecation switch 27 as a defecation-induced cleaning setting means, and an adjusting part 28 for changing the flow rate and temperature of the cleaning water. It is.

Further, a controller 30 which receives a radio signal from the remote controller 23 and controls the components represented by dotted lines in FIG. I have.

FIG. 1 shows only the cleaning nozzle 21 for anal cleaning, and the cleaning nozzle for bidet cleaning has a similar configuration and is separately provided, but the description thereof is omitted here.

FIG. 2 is a top view of the cleaning nozzle 21, and a partial cross section is shown for explanation. The cleaning nozzle 21 has an internal flow path 31 provided therein, and communicates with the ejection port 22.

The jet port 22 is constituted by three round holes, and the washing water jetted from the jet port 22 becomes three shower jets.

The mechanism of inducing constipation includes a case where the physical stimulus given to the anus by the washing water induces a defecation reflex, and a case where the washing water leaking into the anus stimulates the receptor present in the anus. As described above, the defecation reflex may also be induced, but the anus has a property of gradually relaxing when the entrance is physically stimulated.

This is due to the daily fact that the mother of a newborn puppy licks its anus to assist in defecation (stimulates the anus and induces a defecation reflex and relaxes the anus), as well as impaired excretion. There is a method called extirpation as a method of assisting the excretion of those who have stool. It is clear from the fact that the stool is knocked out with a finger to relax the anus (called tapping), and the stool is actually scraped. When the anus is relaxed by the physical stimulus in this way, the flush water in the jet state can leak into the anus relatively easily without discomfort. As a result, it is possible to effectively induce the constipation without causing the washing water to leak into the anus while feeling unpleasant by using a strong water flow that feels pain.

Next, the operation of the first embodiment will be described.
First, the operation during normal cleaning will be described. When the user operates the assembling switch 24 of the remote controller 23 and gives an instruction to start the normal cleaning, the controller 30 opens the original solenoid valve 15 and a predetermined flow of water indicated by the controller 28 of the remote controller 23 is heated. The opening of the flow control valve 16 is adjusted so as to be supplied to the tank 17. With this operation, the pressure of the water supplied from the water supply pipe 14 pushes out the hot water heated and stored at an appropriate temperature in the hot water tank 17 to the hot water pipe 20. Then, the hot water is supplied to the internal flow path 31 provided in the washing nozzle 21 and is jetted from the jet port 22 to the user's anus.

At this time, the flow rate of the washing water can be changed by pressing the control unit 28. Also, the stop switch 26
Is pressed and an instruction to stop washing is given, the controller 30 sequentially closes the original solenoid valve 15 and the flow rate control valve 16 and shifts to a standby state. The controller 3 is provided in the hot water tank 17.
0 controls energization of the heater 18 based on a signal from the thermistor 19, so that warm water of an appropriate temperature is kept warm and stored.

Next, the operation at the time of the incentive-induced cleaning will be described with reference to FIG. FIG. 3 is a time chart showing the operation of the original solenoid valve 15 and the flow control valve 16 after the user presses the bowel movement trigger switch 27 of the remote controller 23 and the bowel movement triggering cleaning is started. As shown in FIG. 3, when an instruction to start cleaning is given, the incentive inducing operation control unit 29 provided in the controller 30 opens the original solenoid valve 15 and sets the flow control valve 16 during the above-described normal cleaning (in the figure). Open to an opening smaller than the dotted line). With this operation, the appropriate-temperature washing water supplied from the hot water tank 17 is jetted from the jet port 22 through the hot water pipe 20 and the internal flow path 31. The valve opening of the flow control valve 16 is set so that the cleaning flow rate at this time is about 60% of that in the normal cleaning, and as shown in FIG.
Is composed of three round holes.
The jets of the book are not completely independent, and as a bodily sensation, it feels like a thick, weak jet. This jet gently stimulates the user's anus and acts as a relaxing jet to promote relaxation of the anus.

After a lapse of a predetermined time from this state, the bowel movement inducing operation control unit 29 holds the flow rate control valve 16 at an opening degree larger than that in the above-described normal cleaning. By this operation, the amount of washing water spouted from the spout 22 is greatly increased,
It is squirted toward the user's anus. The cleaning flow rate at this time was set to be about 50% higher than that in the normal cleaning. Since this jet is a collection of three narrow jets, when the flow rate is increased, each jet is completely independent, and each becomes a strong concentrated jet. Since these three concentrated jets are thin and have high dynamic pressure, they easily leak into the anus during washing, and function as intruding jets. At this time, it is natural that the relationship between the flow rates is as follows: penetration jet> normal jet> relaxed jet.
Normal jet> relaxed jet.

The bowel movement inducing operation control unit 2 provided in the controller 30
Numeral 9 controls to repeat the relaxing jet and the intruding jet at a predetermined cycle as shown in FIG. The predetermined cycle here is a relaxed jet 4
Seconds, and a 10-second cycle of 6 seconds of the immersion jet. This is based on the result of the user's report that relaxation takes place after about 2 to 4 seconds have passed since the relaxation jet began to hit the anus based on the results obtained in the monitoring experiment. As a result, since the infiltrating jet hits the anus whose relaxation has been promoted by the relaxing jet, the washing water easily leaks into the anus, and the user's convenience is effectively induced. In the experiments that were actually performed, it was found that when combined with the relaxed jet, there was a higher probability that the washing water leaked into the anus and the bodily sensation was better than when the washing was performed only with the penetrating jet. It can be said that it is very effective.

Also, by starting the washing with a small flow jet, which is a relaxed jet, it is possible to prevent extra tension in the user's anus,
Care has been taken to provide comfortable bowel movements. This is due to the fact that when excessive stimulation is applied to the anus, the user's own mental state becomes a state of sympathetic nervousness, that is, a state of tension, and in the state of sympathetic nervous state, the anus becomes nervous and relaxation is not promoted. Based.

(Embodiment 2) FIG. 5 is a structural view showing a human body local cleaning apparatus according to Embodiment 2 of the present invention.

In FIG. 5, the water supplied from the water supply pipe 32 is supplied with the original solenoid valve 33 which is a water supply control means for starting and stopping the supply of the cleaning water, and the flow rate which is also a water supply control means for adjusting the flow rate of the cleaning water. Through the control valve 34, it reaches a hot water tank 35 as heating means. The hot water tank 35 includes a heater 36 for heating the water stored inside to an appropriate temperature and a thermistor 37 for detecting the temperature of the hot water inside. Hot water tank 35
The hot water pipes 38 connected to the outlets are branched in two directions, and are provided with switching solenoid valves 39, 4 serving as jet switching means, respectively.
0, the first internal flow path 4 provided in the nozzle unit 41
2, and are connected to the second internal flow path 43, respectively. At the tip of the first internal flow path 42, a first ejection port 44 as a discharge means is provided.
A second ejection port 45, which is also a discharge means, is formed at the tip of the second internal flow path.

An instruction to discharge the washing water from the first jet port 44 and the second jet port 45 is given from the remote controller 46. The remote controller 46 has a buttocks switch 47 for instructing normal anal washing, a bidet switch 48 for instructing washing of the female part, a stop switch 49 for instructing to stop washing, a instinct inducing switch 50 as a instinct inducing washing setting means, washing water. There is provided an adjusting section 51 for varying the flow rate and temperature of the apparatus.

Further, a controller 53 which receives a radio signal from the remote controller 46 and controls the components represented by the dotted lines in FIG. I have.

In FIG. 5, the nozzle unit 41
Indicates only for anal cleaning, and a nozzle unit for bidet cleaning is provided separately with a similar configuration, but the description is omitted here.

FIG. 6 is a top view of the nozzle unit 41, which is partially shown for explanation. The nozzle unit 41 has a first internal flow path 42 and a second internal flow path 43 therein, and a first jet port 44 and a second jet port 45, respectively.
It is connected to the. The first jet port 44 has a single round hole shape, and the washing water jetted from the first jet port 44 becomes a single spot jet. In addition, the second ejection port 45 has a configuration in which a plurality of round holes are regularly arranged on the same circumference, and the jet jetted from this has a shower-like shape in which thin water streams are bundled. . In other words, by selecting whether the washing water is spouted from the first spout 44 or spouted from the second spout 45, the anus is softened in the form of a shower with a penetrating jet that is spot-like and suitable for infiltrating the anus. The configuration is such that the relaxation jet can be switched and selected to stimulate relaxation and promote relaxation. As a matter of course, the cleaning area is larger in the relaxing jet than in the intruding jet.

Next, the operation of the second embodiment will be described.
First, the operation during normal cleaning will be described. When the user operates the buttocks switch 47 of the remote controller 46 and gives an instruction to start normal cleaning, the controller 53 opens the original solenoid valve 33 almost simultaneously with opening the switching solenoid valves 39 and 40. Further, the opening of the flow control valve 34 is adjusted so that a predetermined flow of water specified by the control unit 51 of the remote controller 46 is supplied to the hot water tank 35. Due to the pressure of the water supplied from the water supply pipe 32 by this operation, the hot water heated and stored at an appropriate temperature in the hot water tank 35 passes through the hot water pipe 38, the switching solenoid valves 39 and 40, and the nozzle unit 4
1 is supplied. This hot water is supplied to the first internal flow path 42,
Through the internal flow path 43, the fuel is jetted from both the first jet port 44 and the second jet port 45 to the user's anus. On this occasion,
The flow rate of the washing water can be changed by pressing the control unit 51. Further, when the stop switch 49 is pressed and an instruction to stop washing is issued, the controller 53 causes the original solenoid valve 33 and the flow control valve 3 to stop.
4. The switching solenoid valves 39 and 40 are sequentially closed, and a transition is made to a standby state. The controller 53 is provided in the hot water tank 35.
Is controlled to energize the heater 36 on the basis of the signal of the thermistor 37, so that warm water at an appropriate temperature is kept and stored.

Next, the operation at the time of the incentive-induced cleaning will be described with reference to FIG. FIG. 7 is a time chart showing the operation of the original solenoid valve 33, the flow control valve 34, and the switching solenoid valves 39 and 40 after the user presses the convenience inducing switch 50 of the remote controller 46 and cleaning is started.

As shown in FIG. 7, when an instruction to start cleaning is given, the incentive inducing operation control section 52 provided in the controller 53 opens the switching electromagnetic valve 39 almost at the same time as opening the switching electromagnetic valve 39.
3 and the opening of the flow control valve 34 is controlled by the remote controller 4.
The opening is made to a predetermined opening degree instructed by the adjusting section 51 of No. 6. By this operation, the appropriate-temperature washing water supplied from the hot water tank 35 is jetted from the first jet port 44 from the switching electromagnetic valve 39 via the first internal flow path 42. Here, as shown in FIG. 6, the first jet port 44 is constituted by one round hole, so that the jet jet to be jetted is a spot-like jet, and is in the form of a penetrating jet. However, in order to prevent the anus from being tense by giving an excessive stimulus immediately after the start of washing, the flow rate is set to be small and the washing dynamic pressure is kept low. This weak concentrated jet is a consideration to make it easier for the user to adjust the washing position, and is based on the result of a monitoring experiment that a person is not very accurate in recognizing the position of the washing water hitting near the anus.

Next, when a predetermined time has elapsed from this state,
The bowel movement inducing operation control unit 52 closes the switching electromagnetic valve 39 and opens the switching electromagnetic valve 40, and further adjusts the opening degree of the flow control valve 34 to a predetermined value. By this operation, the washing water supplied from the hot water tank 35 is ejected from the switching electromagnetic valve 40 through the second internal flow path 43 from the second ejection port 45. The opening of the flow rate control valve 34 is set so that the washing flow rate at this time is about 70% of that in the normal washing. Further, as shown in FIG. Since the holes are regularly arranged on the same circumference, the jet becomes a weak shower-like jet. This shower-like jet softly stimulates the user's anus and acts as a relaxing jet to promote relaxation of the anus.

Further, when a predetermined time has elapsed from this state, the bowel movement inducing operation control section 52 again closes the switching electromagnetic valve 40 and opens the switching electromagnetic valve 39, and sets the opening of the flow control valve 34 to the predetermined degree. Adjust to a value. With this operation, the washing water supplied from the hot water tank 35 is ejected again from the first ejection port 44. Note that the cleaning flow rate at this time is set to be about 20% higher than that in the normal cleaning, and the first jet port 44 is constituted by one round hole, so that the jet is a strong concentrated jet. Becomes Since this concentrated jet is thin and has high dynamic pressure, it easily leaks into the anus during washing, and functions as an intruding jet.

As shown in FIG. 7, the convenience inducing operation control section 52 provided in the controller 35 first switches the switching solenoid valve 39.
Is opened, a weak infiltrating jet with a low flow rate is jetted from the first jet port 44, and then the switching electromagnetic valve 40 is opened to release the relaxed jet jet from the second jet port 45 and the switching electromagnetic valve 39. Is controlled so that the inflow jet supplied from the first jet port 44 is repeated at a predetermined cycle.

In this case, the switching between the relaxing jet and the intruding jet is performed in a 10-second cycle of 4 seconds of the relaxing jet and 6 seconds of the injecting jet. As a result, the infiltrating jet is suddenly applied to the anus whose tension has been released by the relaxing jet, so that the washing water easily leaks into the anus, and the user's convenience is effectively induced. In particular, here, the relaxation jet and the infiltration jet are each configured differently, and the relationship of the washing area is defined as the relaxation jet> the infiltration jet, so that the relaxation effect of the relaxation jet can be further improved.
The penetrating jet is more likely to penetrate into the anus. In addition, by flushing the concentrated infiltration jet immediately after the start of cleaning, the cleaning position can be easily adjusted, the probability that the cleaning water leaks into the anus can be greatly improved, and by setting the flow rate of the infiltration jet low, It is configured to prevent anal tension immediately after the start of washing, and to more effectively induce bowel movements.

(Embodiment 3) A third embodiment of the present invention will be described. The third embodiment has the same configuration and the operation at the time of normal cleaning as the second embodiment. Therefore, the description thereof will be omitted, and the inconvenience-inducing cleaning having a partially different operation will be described with reference to FIGS.

Embodiment 3 is different from Embodiment 2 in that
As is clear from FIG. 8, the duration of the infiltrating jet is constant and the duration of the relaxing jet is within the repetition period of the relaxing jet ejected from the second jet and the injecting jet ejected from the first jet 44. Is changed irregularly. This means that the convenience inducing operation control unit 52 provided in the controller 53 irregularly changes the opening of the flow rate control valve 34 to a predetermined value at the time of the infiltration jet, and the time for which the switching solenoid valve 40 is kept open. This is achieved by:

The duration of the intruding jet is 4
Seconds, the duration of the relaxing jet was set to an irregular value of 2 to 8 seconds. As a result, since the infiltrating jet hits the anus whose relaxation has been promoted by the relaxing jet, the washing water easily leaks into the anus, and the user's convenience is effectively induced. In particular, here, since the duration of the relaxing jet is not constant, the user cannot predict at what timing the intruding jet is jetted,
It is possible to increase the probability that the washing water enters the anus. In addition, it is possible to perform cleaning for comfort inducing comfort by eliminating monotonous feeling.

Although the duration of the intruding jet is constant in this embodiment, it may be irregularly varied, or the duration of the relaxing jet and the intruding jet may be irregularly varied.

A meandering water channel 79 is provided on both sides of the nozzle 8. When the ceramic heater 78 is energized and the temperature rises, the heat is transmitted to the water flowing through the water channel 79 to generate hot water.

In FIG. 9, the nozzle unit 6
Reference numeral 3 indicates only the anus, but the bidet cleaning nozzle unit is separately provided with a similar configuration, and the expression on the drawing is omitted.

FIGS. 10 and 11 show the details of the cleaning nozzle 64, and FIGS. 12 and 13 show image diagrams of the shape of the cleaning jet.

FIG. 10 is a top view of the cleaning nozzle 64 as viewed from above, and FIG. 11 is a cutaway cross-sectional view as viewed from the side. FIG. 11 shows an image of a jet when air is mixed, and FIG. 12 shows an image of a jet when air is not mixed. As shown in FIG. 11, the flow path in the cleaning nozzle 64 gradually decreases in cross section from the flow path 80 formed in the nozzle unit 63 to the flow paths 81 and 82 in the cleaning nozzle. Through the parallel portion 84 and the enlarged portion 8
5 is configured to expand slightly in a trumpet shape.

With this configuration, the cleaning jet at the time of air mixing (hereinafter, referred to as “air mixing jet”) is formed by the air mixing and the expanding section 85.
As shown in FIG. 12, the washing water is supplied to the human body part in a state of being swung over a relatively wide range. Also,
The cleaning jet (hereinafter, referred to as "direct jet") when the mixing of air is stopped is discharged in a spot in a relatively narrow range in a direct jet state by the action of the parallel portion 84 as shown in FIG.

Next, the operation of this embodiment will be described.
First, the operation during normal cleaning will be described. The ass switch 71 is operated while the user is seated on the toilet seat 68,
When the normal cleaning is instructed, the controller 77 controls the three-way valve 86 to open the flow path on the toilet cleaning nozzle 87 side. Then, after opening the original solenoid valve 55, the flow control valve 57 is opened to a predetermined opening, and the signal of the flow sensor 58 is taken in. Here, if the flow rate read signal from the flow rate sensor 58 is 100 cc / min or more, it is determined that there is water flow in the heat exchanger 59, and the power supply to the ceramic heater 78 provided in the heat exchanger 59 is started to perform cleaning. Heat the water. Then, while controlling the flow rate control valve 57 so as to have a predetermined flow rate value set by the control unit 74 of the remote controller 70, the hot water temperature signal from the hot water thermistor 62 is read, and the ceramic heater 78 is controlled to have the predetermined hot water temperature. Is varied. Further, when the temperature of the hot water reaches a predetermined value, the front-rear drive motor 65 is driven to cause the cleaning nozzle 64 to protrude to a predetermined position, and the three-way valve 86 is controlled to open a flow path on the nozzle unit 63 side, The hot water is led to the cleaning nozzle 64. At the same time, the air pump 66 is driven to mix air into the washing water.

The washing water whose flow rate has been adjusted by the flow control valve 57 and which has been heated to an appropriate temperature by the heat exchanger 59 is supplied to the air pump 66.
After the air is mixed through the air pipe 67, the air reaches the nozzle unit 63, and is discharged from the cleaning nozzle 64 to the human body. Since the washing jet here is the above-described aerated jet, a relatively wide area of the human body part is swung and washed. In addition, the flow rate can be improved without impairing the cleaning effect and the user's bodily sensation as compared with the conventional cleaning using only warm water due to the improvement of the ejection speed at the nozzle opening 83 due to the mixing of air and the effect of popping the mixed air. Can be washed in less than half.

Further, by using the instantaneous heat exchanger 59, compared with the conventional hot water storage type heating means, there is no heat loss at the time of storing hot water, and the flow rate of washing water is reduced by half. A significant reduction in power consumption can be achieved. Furthermore, since the flushing water is supplied to the toilet flushing nozzle 87 for a period of time from when the flushing start instruction is given to when the warming water is supplied, the warming water is jetted when the flushing water actually hits the anus. Comfort can be prevented from being impaired.

Further, since residual chlorine contained in tap water and also referred to as a cause of anal pruritus is removed by the filter 56, it is considered that long-term washing does not adversely affect the local human body. I have. Furthermore, in the conventional hot water storage type human body local cleaning device, since hot water is heated and stored in the hot water tank, bacteria are propagated in the hot water tank by removing residual chlorine, and instead, the human body local cleaning device is used. Although this may have an adverse effect, the instantaneous heat exchanger 59 is employed here, so there is no such concern. Here, the filter 56 is made of activated carbon, but may be made of an ion exchange resin, a chemical such as sodium thiosulfate or calcium sulfite, or a catalyst using tungsten, titanium, or molybdenum.

Next, the operation at the time of the incentive-induced cleaning will be described. Next, the operation at the time of the incentive-induced cleaning will be described with reference to FIG. FIG. 14 is a time chart showing the operation of the original solenoid valve 55, the flow control valve 57, and the air pump 66 when the user presses the bowel movement trigger switch 75 of the remote controller 70 and the start of bowel movement triggering is instructed. The operation of each component from the start of cleaning until the cleaning nozzle 64 protrudes and the flow path on the nozzle unit 63 side is opened by the three-way valve 86 is almost the same as during normal cleaning. The operation after the projection of 64 is mainly shown.

In FIG. 14, after the cleaning start instruction is given, the cleaning nozzle 64 projects, and the three-way valve 86 opens the flow path on the nozzle unit 63 side. The unit 76 keeps the state for a predetermined time, and then turns the air pump 49 on and off at a predetermined voltage for a predetermined cycle. And furthermore, the air pump 6
When 6 is ON, the flow control valve 57 is held at a predetermined opening, and the flow control valve 57 is opened greatly in synchronization with the OFF of the air pump 66. Here, the air pump 6
The opening of the flow control valve 57 is adjusted so that the flow rate of the cleaning water is the same as that during normal cleaning when 6 is ON, and about twice the flow rate during normal cleaning when OFF. It has been set. The applied voltage is set so that the amount of air sent into the washing water by the air pump 66 is about 80% of the amount during normal washing. However, the opening of the flow control valve 57 immediately after the three-way valve 86 opens the flow path on the nozzle unit 63 side is set to be equal to or slightly smaller than that in the normal cleaning. This is a consideration for facilitating the user's cleaning alignment by ejecting a direct jet with a small flow rate.

Also, when the aerated jet is being ejected,
That is, when the air pump 66 is ON,
The controller 77 varies the amount of electricity supplied to the ceramic heater 78 to supply relatively lukewarm (37 ° C.) hot water. Immediately before switching to the direct jet flow, that is, the air pump 66
Immediately before turning off the heater, the amount of electricity to the ceramic heater 78 is increased to increase the hot water temperature at the start of direct jet ejection (4).
(0 ° C.).

As a result, the aerated jet in the fourth embodiment is set to have a less stimulating and warmer warm water than that in the normal washing, which stimulates the anus softly with a soft water flow, and makes the anus soft. It is effective in relaxing the anus with warm water and promoting anal relaxation. Furthermore, the direct jet from which air is stopped is a relatively strong concentrated jet due to a large increase in the flow rate, and is suitable for leaking into the anus. Further, since the warm water is jetted at the start of jetting of the direct jet, there is also an effect of giving a thermal stimulus to the anus and inducing constipation.

The cycle of repetition of the aerated jet and the direct jet in Example 4 was an 8-second cycle of 2 seconds of the aerated jet and 6 seconds of the direct jet. As a result, the suddenly concentrated jet hits the anus whose relaxation is promoted by the aerated jet, so that the washing water easily leaks into the anus, and the user's convenience is effectively induced. In addition, the adoption of the instantaneous heat exchanger 59 enables continuous long-time cleaning, which greatly contributes to inducing convenience. In other words, prolonged irrigation promotes relaxation of the anus, which makes it easier for the irrigation water to leak into the anus, and by stimulating the bowel peristalsis by inducing a continuous defecation reflex. it can. Further, the instantaneous heat exchanger 59 has a small heat capacity, so that the temperature of the hot water to be supplied can be quickly changed, and a temperature stimulus can be given to the anus.

Since the flow rate of the cleaning water changes greatly at the time of the direct jet discharge in the fourth embodiment, the controller 77 greatly changes the amount of electricity supplied to the ceramic heater 78 to supply the cleaning water at an appropriate temperature. Control is performed so that it can be obtained. However, in winter, when the incoming water temperature is extremely low and there is insufficient capacity to boil water at the set flow rate, the flow rate control valve 57 is controlled to control the flow rate to a point where it can be boiled to an appropriate temperature. .

(Embodiment 5) A fifth embodiment of the present invention will be described. The fifth embodiment is the same as the fourth embodiment in the configuration and the operation at the time of normal cleaning. Therefore, the description thereof will be omitted, and a description will be given of the operation at the time of the inconvenience-inducing cleaning which is partially different in operation with reference to FIG.

FIG. 15 is a time chart showing the operation of the original solenoid valve 55, the flow control valve 57, and the air pump 66 when the user presses the defecation induction switch 75 of the remote controller 70 and the defecation-induced cleaning is started.

In FIG. 15, when an instruction to start washing is given, the controller 77 opens the flow path on the toilet washing nozzle 87 side, opens the original solenoid valve 55, and opens the flow control valve 57 to a predetermined opening degree. When the temperature of the cleaning water reaches a predetermined value, the cleaning nozzle 45 is discharged, and then the flow path on the nozzle unit 63 side is opened, and the state is maintained for a predetermined time. After a lapse of a predetermined time, the air pump 66 is started at a predetermined voltage. Here, the convenience inducing operation control unit 76 provided in the controller 77 controls the flow rate control valve 57 so that the amount of washing water increases and decreases in a predetermined cycle. The opening is adjusted in two stages. The voltage applied to the air pump 66 is also changed in two stages in synchronization with the opening adjustment of the flow control valve 39. As is clear from FIG. 14, the voltage applied to the air pump 66 is set high when the opening of the flow control valve 57 is small, and the voltage applied to the air pump 66 is set low when the opening of the flow control valve 57 is large. I have. Here, when the opening degree of the flow rate control valve 57 is small, the opening degree is set so that the flow rate of the washing water becomes the same as that of the normal washing. Is set to be about 80% of the value. When the opening degree of the flow control valve 57 is large, the opening degree is set so that the flow rate of the washing water is about 1.5 times that in the normal washing, and the voltage applied to the air pump 66 depends on the amount of air to be sent. It is set to be about 20% of the value during normal cleaning.

With these operations, the flow rate of the cleaning jet jetted from the cleaning nozzle 64 changes at a predetermined cycle, so that the user's bodily sensation greatly changes and intermittent stimulation is given to the anus. When the opening degree of the flow control valve 57 is small, the same jet as the air-mixed jet of the third embodiment is obtained, and the anus is softly stimulated with a softer water stream as compared with the time of normal washing, thereby promoting the relaxation of the anus. It is effective for Also, the flow control valve 57
When the opening is large, the ratio of the air mixed into the washing water is much smaller than when the opening is small, so that the jet becomes a slightly thicker direct jet in the third embodiment. . This is because, as the amount of air is reduced, the repelling action is also significantly reduced, so that the air does not diffuse widely as in the case of the aerated jet. However, if air is mixed in even a small amount, the apparent volume of the cleaning water increases, and the flow velocity of the cleaning water ejected from the nozzle port 83 is improved by the proportion. Therefore, if the flow rate of the washing water is the same, the user feels stronger when a small amount of air is mixed, and the sensation is improved by making the washing jet slightly thicker. For this reason, even if the flow rate of the washing water is reduced, it is possible to obtain a jet that is sufficient to leak into the anus and has an excellent bodily sensation.

Note that, also in the fifth embodiment, the cycle of repetition of the aerated jet and the direct jet is an 8-second cycle of 2 seconds of the aerated jet and 6 seconds of the direct jet. As a result, a concentrated jet with a small amount of air abruptly hits the anus whose relaxation is promoted by the aerated jet, so that the washing water easily leaks into the anus and effectively induces the user's convenience. Is done. In addition, in the fourth embodiment, although the concentrated jet is small in amount, air is mixed therein, so that it is excellent in the bodily sensation, and it is possible to inject the washing water into the anus with a small amount of washing water as compared with the case where no air is mixed. Can be.

As described above, according to the apparatus for cleaning a human body part of the present invention, the following effects can be obtained.

(1) By properly controlling the heating means and the water supply control means in accordance with the setting of the constipation-inducing cleaning setting means, it is possible to clean the human body with a cleaning jet suitable for inducing consent, and as a result use Positively induces the defecation of the person and assists in comfortable defecation. In addition, since the apparatus is provided with the normal cleaning setting means and the constipation-inducing cleaning setting means, the cleaning jet can be selectively used depending on the situation, and the usability of the user is improved.

(2) Relaxing jet <
Since the normal jet is smaller than the relaxed jet, the relaxing effect of the relaxed jet is further enhanced, and the penetrating jet easily penetrates into the anus. Further, the change in the washing dynamic pressure when switching from the relaxed jet to the intruding jet becomes large, so that the anus can be effectively stimulated, and the effect of inducing constipation can be enhanced.

(3) The jet switching means has a configuration in which the form of the relaxing jet and the intruding jet can be varied, and the relationship of the washing area is defined as the relaxing jet> the injecting jet. In addition to providing a moderate stimulus to further improve the relaxation effect, the intruding jet hits a small area and easily penetrates into the anus, so that the user's convenience can be more effectively induced.

(4) Since the duration of the relaxing jet and the duration of the intruding jet within the repetition period are set, the degree of relaxation of the anus and the degree of penetration of the washing water greatly depend on the duration of each jet. It can respond flexibly, effectively promote relaxation of the anus, and increase the probability of water penetration into the anus.

(5) By setting the duration of the relaxation jet within the repetition cycle to 2 seconds or more, the user's anal relaxation can be further promoted, and consequently the user's feelings can be effectively induced.

(6) Irregularly changing the duration of at least one of the relaxing jet and the intruding jet within the repetition cycle eliminates the monotonous feeling, and unexpectedly applies the intruding jet to the inside of the anus. The infiltration probability of the washing water is improved, and the user's feelings can be more effectively induced.

(7) When the incentive-induced washing setting means is selected and set, washing is started with a relaxing jet to promote relaxation of the anus from immediately after the start of washing, and the anus generated by suddenly hitting a strong jet. Tension can be prevented.

(8) When the incentive-induced cleaning setting means is selected and set, the jet area at the start of cleaning is set to a penetration jet, so that the cleaning area at the start of cleaning becomes small.
The user can easily adjust the cleaning position, and the probability that the cleaning water leaks into the anus can be improved.

(9) When the incentive-induced cleaning setting means is selected and set, by using an intruding jet with a reduced flow rate as the jet at the start of cleaning, the user can easily perform the cleaning position adjustment and start the cleaning. Prevents occasional anal tension and promotes anal relaxation.

(10) The instantaneous heat exchanger is used as the heating means, and the temperature of the washing water supplied is variably controlled in synchronization with the switching time between the relaxing jet and the intruding jet, thereby switching between the relaxing jet and the intruding jet. In addition to the stimulus pressure change that sometimes occurs, a stimulus due to a change in the temperature of the washing water is given to the anus, so that the user's convenience can be more effectively induced.
