[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a human body local cleaning device that can actively induce a user's convenience and promote defecation.
[0002]
[Prior art]
  FIG. 15 shows a block diagram of a water channel of a hot water cleaning apparatus using this type of conventional human body local cleaning apparatus, and FIG. 16 shows a sectional view of a cleaning nozzle used here. In the figure, reference numeral 1 denotes a cleaning nozzle having a jet nozzle 2, and 3 denotes a hot water tank for heating and storing cleaning water, and a heater 4 is provided therein. 5 is a water pump for supplying cleaning water, and 6 is an original solenoid valve. The washing nozzle 1 is provided in a pair of vortex chambers 10 and 11 and a pair of vortex chambers 10 and 11 and vortex chambers 10 and 11 provided on both sides of the narrowing portion 7 and the adhering walls 8 and 9 provided on both sides of the jet outlet 2. A fluid oscillation element type cleaning nozzle 1 is formed having intake pores 12 and 13.
[0003]
  In this configuration, when hot water from the hot water tank 3 flows into the cleaning nozzle 1, the flow velocity is increased by passing through the throttle portion 7, and adheres to, for example, the adhesion wall 8 side by the Coanda effect (fluid adhesion effect). Erupts in the direction of. At this time, the washing water flows into the vortex chamber 10 and the vortex flow is generated, whereby air is sucked from the intake pores 12 and the pressure of the vortex chamber 10 is increased. This pressure acts to move the water flow toward the adhering wall 9 and the jet flow moves to the arrow B side. By repeating these operations, a self-oscillation state occurs, and cleaning is performed while the jet flow is oscillating. As the water flow oscillates in this way, the cleaning power is improved, and a rhythmic pressure stimulus is applied to the anus during the cleaning to induce an anal reflex.
[0004]
[Problems to be solved by the invention]
  In order to make the user feel comfortable using the wash water of the human body local washing device, a method of inducing a defecation reflex by physically stimulating the anus with the wash water ejected vigorously, and the wash water in the anus There is also a method of stimulating the receptive sensory organs present in the anus of the human body by leaking into the anus and also inducing a defecation reflex. The former has been confirmed by animal experiments, that is, a large contraction in the colon caused by mechanical anal stimulation to dogs with brain loss or spinal cord injury. In the latter case, the state of diarrhea, or the state immediately after infusion of enema fluid, is simulated and reproduced by washing water that leaks. In this state, the internal anus is a strong inconvenience and is an involuntary muscle. The sphincter muscles relax. These are well-known facts at related academic societies.
[0005]
  Based on the above, in the conventional configuration described above, although there is a certain convenience inducing effect due to pressure stimulation of the washing water, it is rare to leak into the anus because the washing water always oscillates at a predetermined cycle. In other words, it is impossible to induce constipation due to enema action due to the leakage of washing water into the anus. If the flow rate of washing water is increased and the washing dynamic pressure is increased, the washing water easily leaks into the anus. On the other hand, the sensation at the time of washing deteriorates, and in severe cases, even a painful sensation results. As described above, there is a problem that a clear constipation inducing effect cannot be expected.
[0006]
  The present invention solves the above-mentioned problems, and provides a human body local cleaning device that can be used comfortably without causing a user to feel disgust or pain and can induce constipation very effectively.
[0007]

[0025]
【Example】
  Embodiments of the present invention will be described below with reference to the drawings.
[0026]
  Example 1
  FIG. 1 is a diagram showing components of the human body local cleaning device according to the first embodiment of the present invention.
[0027]
  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 wash water, and the same water supply control means for adjusting the flow rate of the wash water and the jet strength. , And reaches the hot water tank 17 through a flow rate adjusting valve 16 which is also a jet switching means for switching between a normal jet, a relaxed jet, and an intruding jet. The hot water tank 17 includes a heater 18 that is a heating unit that heats water stored in the interior to an appropriate temperature, and a thermistor 19 that detects the temperature of the internal hot water. The outlet of the hot water tank 17 is connected to a cleaning nozzle 21 via a hot water pipe 20, and a jet port 22 as discharge means is formed at the tip of the cleaning nozzle 21.
[0028]
  The washing water is discharged from the jet port 22 according to an instruction from the remote controller 23. The remote control 23 has a normal rinsing setting means urine switch 24 for instructing normal anus cleaning, a bidet switch 25 for instructing female local washing, a stop switch 26 for instructing cessation of washing, and a sensation inducing as constipation inducing washing setting means. A switch 27, an adjustment unit 28 for changing the flow rate and temperature of the cleaning water, and the like are provided.
[0029]
  In addition, a controller 30 is provided that receives a radio signal from the remote controller 23 and controls the components represented by the dotted line in FIG.
[0030]
  In FIG. 1, the cleaning nozzle 21 is shown only for anal cleaning, and the cleaning nozzle for bidet cleaning is separately provided with a similar configuration, but description thereof is omitted here.
[0031]
  FIG. 2 is a top view of the cleaning nozzle 21, and a partial cross-sectional view is shown for explanation. The cleaning nozzle 21 is provided with an internal flow path 31 and communicates with the ejection port 22.
[0032]
  The jet port 22 is composed of three round holes, and the wash water jetted from here is a three shower-like jet.
[0033]
  In addition, the mechanism that induces constipation includes the case where the physical stimulus given to the anus by the wash water induces the defecation reflex, and the case where the wash water that has leaked into the anus stimulates the receptor present in the anus and also causes defecation. As described above, the reflex may be induced, but the anus has a property of gradually relaxing when the entrance is physically stimulated.
[0034]
  This is a daily fact that the mother of a newborn puppy licks the anus to help defecate (stimulates the anus, induces the defecation reflex and relaxes the anus), or has difficulty in excretion There is a method called stool excretion, and it is clear from the fact that when the stool is removed, the anus is relaxed by knocking with a finger (called tapping) and the stool is actually scraped. When the anus relaxes due to the physical stimulation in this manner, the washing water in the jet state can leak into the anus relatively easily without discomfort. As a result, it is possible to effectively induce constipation without causing the washing water to leak into the anus while feeling uncomfortable using a strong water flow that feels painful.
[0035]
  Next, the operation of the first embodiment will be described.
[0036]
  First, the operation during normal cleaning will be described. When the user operates the butt switch 24 of the remote controller 23 and is instructed to start normal cleaning, the controller 30 opens the original solenoid valve 15, and the predetermined flow rate of water indicated by the adjustment unit 28 of the remote controller 23 is hot water. The opening degree of the flow control valve 16 is adjusted so as to be supplied to the tank 17. By this operation, the pressure of the water supplied from the water supply pipe 14 pushes the hot water heated and stored at an appropriate temperature in the hot water tank 17 to the hot water pipe 20. And this warm water is supplied to the internal flow path 31 provided in the washing nozzle 21, and is jetted from the jet nozzle 22 to a user's anus.
[0037]
  At this time, the flow rate of the washing water can be changed by pushing the adjusting unit 28. In addition, when the stop switch 26 is pressed and an instruction to stop cleaning is given, the controller 30 sequentially closes the original solenoid valve 15 and the flow rate adjustment valve 16 and shifts to a standby state. In the hot water tank 17, the controller 30 energizes and controls the heater 18 based on a signal from the thermistor 19, so that warm water having an appropriate temperature is stored.
[0038]
  Next, the operation during stool induction cleaning will be described with reference to FIG. FIG. 3 is a time chart showing the operations of the original solenoid valve 15 and the flow rate control valve 16 after the user presses the stool induction switch 27 of the remote controller 23 and the stool induction cleaning is started. As shown in FIG. 3, when an instruction to start cleaning is given, the convenience control operation control unit 29 provided in the controller 30 opens the original electromagnetic valve 15 and the flow rate adjusting valve 16 during the above-described normal cleaning (in the drawing). Open to an opening smaller than the dotted line. As a result of this operation, the wash water of an appropriate temperature 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. Note that the opening degree of the flow rate adjusting valve 16 is set so that the cleaning flow rate at this time is about 60% of that during normal cleaning, and the jet port 22 has three round holes as shown in FIG. However, if the flow rate is small, the three jets cannot be completely independent, and the body feels as if a thick, weak jet is hit. This jet acts as a relaxing jet that softly stimulates the user's anus and promotes anal relaxation.
[0039]
  When a predetermined time elapses from this state, the constipation inducing action control unit 29 holds the flow rate adjustment valve 16 at an opening larger than that during the normal cleaning described above. By this operation, the amount of the washing water ejected from the ejection port 22 is greatly increased and ejected toward the user's anus. The cleaning flow rate at this time was set to be about 50% higher than that during normal cleaning. Since this jet is a group of three thin jets, when the flow rate is increased, each jet becomes completely independent, and each becomes a strong concentrated jet. Since these three concentrated jets are thin and have high dynamic pressure, they tend to leak into the anus during washing and function as an intrusion jet. Also, as a matter of course, the relationship between the flow rates is infiltration jet> normal jet> relaxation jet, and the relationship between these washing dynamic pressures is also infiltration jet> normal jet> relaxation jet.
[0040]
  As shown in FIG. 3, the stool inducing action control unit 29 provided in the controller 30 performs control to repeat the relaxation jet and the intrusion jet in a predetermined cycle. Here, the predetermined cycle was a 10-second cycle of a relaxing jet 4 seconds and an intruding jet 6 seconds. This is based on the user's report that the relaxation progresses after a time of about 2 to 4 seconds has passed since the relaxation jet started to hit from the result obtained from the result of the monitor experiment. As a result, the invasion jet hits the anus whose relaxation is promoted by the relaxation jet, so that the washing water easily leaks into the anus, and the user's convenience is effectively induced. In actual experiments, it was found that there was a higher probability of washing water leaking into the anus when combined with a relaxing jet than in the case of cleaning with only an intruding jet, and the sensation of feeling was superior. It can be said that it is very effective.
[0041]
  In addition, by starting washing with a small jet, which is a relaxing jet, it is possible to prevent excessive tension in the user's anus and to perform comfortable sensation-induced washing. This is due to the fact that if excessive stimulation is applied to the anus, the user's own mental state becomes sympathetic dominant, that is, tension, and in the sympathetic dominant state, the anus also becomes tense and relaxation is not promoted. Based.
[0042]
  (Example 2)
  FIG. 5 is a block diagram showing a human body local cleaning device according to a second embodiment of the present invention.
[0043]
  In FIG. 5, the water supplied from the water supply pipe 32 is an original electromagnetic valve 33 which is a water supply control means for starting and stopping the supply of the wash water, and a flow rate adjusting valve 34 which is also a water supply control means for adjusting the flow rate of the wash water. Then, it reaches the hot water tank 35 which is a heating means. The hot water tank 35 includes a heater 36 that heats the water stored therein to an appropriate temperature, and a thermistor 37 that detects the temperature of the internal hot water. A hot water pipe 38 connected to the outlet of the hot water tank 35 branches in two directions, and a first internal flow path 42 provided in the nozzle unit 41 via switching electromagnetic valves 39 and 40 which are jet switching means, Each is connected to the second internal flow path 43. A first jet outlet 44 that is a discharge means is formed at the tip of the first internal flow path 42, and a second jet outlet 45 that is also a discharge means is formed at the tip of the second internal flow path.
[0044]
  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 control 46 includes a butt switch 47 for instructing normal anus cleaning, a bidet switch 48 for instructing female local cleaning, a stop switch 49 for instructing to stop cleaning, a stool inducing switch 50 as a stool inducing irrigation setting unit, washing water The adjustment part 51 etc. which vary the flow volume and temperature of this are provided.
[0045]
  Further, a controller 53 is provided which receives a radio signal from the remote controller 46 and controls the components represented by the dotted line in FIG.
[0046]
  In FIG. 5, the nozzle unit 41 is shown only for anal cleaning, and the bidet cleaning nozzle unit is separately provided with a similar configuration, but the description thereof is omitted here.
[0047]
  FIG. 6 is a top view of the nozzle unit 41, and a partial cross-sectional view is shown for explanation. The nozzle unit 41 has a first internal flow path 42 and a second internal flow path 43 provided therein, and is connected to a first jet outlet 44 and a second jet outlet 45, respectively. The first jet port 44 has a single round hole shape, and the wash water ejected from the first jet port 44 is a single spot-like jet. Moreover, the 2nd jet nozzle 45 becomes a structure by which several round holes are regularly arrange | positioned on the same periphery, and the jet flow spouted from here becomes a shower-like thing with which the thin water flow was bundled. . In other words, by selecting whether the washing water is ejected from the first ejection port 44 or the second ejection port 45, the anus is soft in the form of a spot and an infiltration jet suitable for entering the anus. It is possible to switch between relaxing jets that stimulate the relaxation and promote relaxation. As a matter of course, the washing area is wider for the relaxation jet than for the intrusion jet.
[0048]
  Next, the operation of the second embodiment will be described.
[0049]
  First, the operation during normal cleaning will be described. When the user operates the butt switch 47 of the remote controller 46 and gives an instruction to start normal cleaning, the controller 53 opens the original electromagnetic valve 33 almost simultaneously with opening the switching electromagnetic valves 39 and 40. Further, the opening degree of the flow rate adjustment valve 34 is adjusted so that a predetermined flow rate of water indicated by the adjustment 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 in the hot water tank 35 at an appropriate temperature is supplied to the nozzle unit 41 via the hot water pipe 38 and the switching electromagnetic valves 39 and 40. This hot water is jetted from both the first jet port 44 and the second jet port 45 to the user's anus via the first internal channel 42 and the second internal channel 43. At this time, the flow rate of the washing water can be changed by pushing the adjustment unit 51. Further, when the stop switch 49 is pressed and a washing stop instruction is issued, the controller 53 sequentially closes the original solenoid valve 33, the flow rate control valve 34, and the switching solenoid valves 39 and 40, and shifts to a standby state. In the hot water tank 35, the controller 53 controls the heater 36 based on the signal from the thermistor 37.Energization control and proper temperatureHot water is stored warm.
[0050]
  Next, the operation during stool induction cleaning will be described with reference to FIG. FIG. 7 is a time chart showing the operations of the original solenoid valve 33, the flow rate adjusting valve 34, and the switching solenoid valves 39 and 40 after the user presses the stool inducing switch 50 of the remote controller 46 and the cleaning is started.
[0051]
  When an instruction to start cleaning is given as shown in FIG. 7, the convenience control operation control unit 52 provided in the controller 53 opens the original electromagnetic valve 33 almost simultaneously with opening the switching electromagnetic valve 39, and the flow rate The opening of the control valve 34 is opened to a predetermined opening indicated by the adjusting unit 51 of the remote controller 46. As a result of this operation, wash water having an appropriate temperature supplied from the hot water tank 35 is ejected from the switching solenoid valve 39 through the first internal flow path 42 and from the first ejection port 44. Here, as shown in FIG. 6, the first jet port 44 is configured by one round hole, so that the jet jetted is one spot-like, and is an intrusion jet. However, in order to prevent the anus from becoming tense by giving an excessive stimulus immediately after the start of cleaning, the flow rate is set to be small and the cleaning dynamic pressure is kept low. This weak concentrated jet is a consideration for making it easier for the user to adjust the cleaning position, which is based on the result of a monitoring experiment that the person is not so accurate with respect to the position recognition of the cleaning water that hits the anus.
[0052]
  Next, when a predetermined time elapses from this state, the constipation inducing action 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. To do. By this operation, the wash water supplied from the hot water tank 35 is ejected from the switching solenoid valve 40 through the second internal flow path 43 and from the second ejection port 45. Note that the opening degree of the flow rate adjusting valve 34 is set so that the cleaning flow rate at this time is about 70% of that during normal cleaning. 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 acts as a relaxing jet that softly stimulates the user's anus and promotes anal relaxation.
[0053]
  Further, when a predetermined time elapses from this state, the constipation inducing action control unit 52 again closes the switching electromagnetic valve 40 and opens the switching electromagnetic valve 39, and the opening degree of the flow rate control valve 34 becomes a predetermined value. Adjust as follows. By this operation, the wash water supplied from the hot water tank 35 is again ejected from the first ejection port 44. The cleaning flow rate at this time is set to be about 20% higher than that during normal cleaning, and the first jet port 44 is composed of one round hole, so that the jet is a strong concentrated jet. It becomes. Since this concentrated jet is thin and has high dynamic pressure, it easily leaks into the anus during washing, and acts as an intrusion jet.
[0054]
  As shown in FIG. 7, the convenience control operation control unit 52 provided in the controller 35 first opens the switching electromagnetic valve 39 and then ejects a weak intrusion jet whose flow rate is set low from the first jet outlet 44. Then, the relaxing jet flow that is ejected from the second jet port 45 by opening the switching electromagnetic valve 40 and the intrusion jet flow that is supplied from the first jet port 44 by repeating the switching electromagnetic valve 39 are repeated at a predetermined cycle. Take control.
[0055]
  In this case as well, the switching between the relaxing jet and the intruding jet is set to a 10-second cycle of the relaxing jet 4 seconds and the intruding jet 6 seconds. As a result, since the intruding jet suddenly hits the anus whose tension has been released by the relaxing jet, the washing water easily leaks into the anus, and the user's convenience is effectively induced. In particular, here, the relaxation jet and the intrusion jet have different forms, and the relationship between the washing areas is set as relaxation jet> infiltration jet, so that the relaxation effect of the relaxation jet can be further improved, and the invasion jet is more in the anus. It is easy to enter. In addition, it is easy to align the cleaning position by ejecting the concentrated intrusion jet immediately after the start of cleaning, greatly improving the probability that the cleaning water leaks into the anus, and by setting the flow rate of the intrusion jet low, It is configured to prevent anal tension immediately after the start of washing and induce constipation more effectively.
[0056]
  (Example 3)
  A third embodiment of the present invention will be described. Since the configuration and operation of the third embodiment in the third embodiment are the same as those in the second embodiment, the description thereof will be omitted, and the convenience-inducing cleaning in which some operations are different will be described with reference to FIGS. 5 and 8.
[0057]
  The third embodiment is different from the second embodiment, as is apparent from FIG. 8, within the repetition cycle of the relaxed jet ejected from the second jet outlet and the infiltrating jet jet ejected from the first jet outlet 44. The duration of the intrusion jet is constant and the duration of the relaxation jet is changed irregularly. This is because the constipation inducing action control unit 52 provided in the controller 53 irregularly changes the opening time of the flow control valve 34 to a predetermined value at the time of the intrusion jet, and the switching electromagnetic valve 40 is kept open. This is realized.
[0058]
  Here, the duration of the intrusion jet was set to an irregular value of 4 seconds, and the duration of the relaxation jet was set to an irregular value of 2 to 8 seconds. As a result, the invasion jet hits the anus whose relaxation is promoted by the relaxation jet, so that the washing water easily leaks into the anus, and the user's convenience is effectively induced. In particular, here, since the duration of the relaxation jet is not constant, the user cannot predict at which timing the intruding jet is ejected, and it is possible to improve the probability that the washing water enters the anus. In addition, the monotonous feeling can be eliminated and the washing for inducing constipation can be performed.
[0059]
  In this embodiment, the duration of the intrusion jet is constant, but it may be irregularly varied, or the duration of both the relaxation jet and the intrusion jet may be irregularly varied.

  In addition, a controller 77 is provided that receives a radio signal from the remote controller 70 and controls the components represented by the dotted line in FIG.
[0065]
  Further, the heat exchanger 59 has a structure in which meandering water channels 79 are provided on both sides of the ceramic heater 78, and when the ceramic heater 78 is energized and heated, the heat is transferred to the water flowing through the water channel 79 to produce hot water. It has become.
[0066]
  In FIG. 9, the nozzle unit 63 is shown only for anus, but the bidet cleaning nozzle unit is separately provided in a similar configuration, and the expression on the drawing is omitted.
[0067]
  10 and 11 show details of the cleaning nozzle 64, and FIGS. 12 and 13 show conceptual views of the shape of the cleaning jet.
[0068]
  FIG. 10 is a top view of the cleaning nozzle 64 as seen from above, and FIG. 11 is a cut-away sectional view as seen 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 no air is mixed. As shown in FIG. 11, the flow path in the cleaning nozzle 64 gradually decreases from the flow path 80 formed in the nozzle unit 63 to the flow paths 81 and 82 in the cleaning nozzle, and the vicinity of the nozzle port 83. Then, after passing through the parallel portion 84, the enlargement portion 85 is slightly enlarged in a trumpet shape.
[0069]
  With this configuration, the cleaning jet at the time of air mixing (hereinafter referred to as “air mixing jet”) is in a state where the cleaning water is swung in a relatively wide range as shown in FIG. Supplied to human body parts. Further, as shown in FIG. 13, the cleaning jet when the mixing of air is stopped (hereinafter referred to as “direct jet”) is spot-discharged in a relatively narrow range in the direct injection state by the action of the parallel portion 84.
[0070]
  Next, the operation of this embodiment will be described.
[0071]
  First, the operation during normal cleaning will be described. When the butt switch 71 is operated while the user is seated on the toilet seat 68 and normal washing is instructed, the controller 77 controls the three-way valve 86 to open the flow path on the toilet washing nozzle 87 side. Then, after opening the original electromagnetic 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 reading signal from the flow rate sensor 58 is 100 cc / min or more, it is determined that there is water in the heat exchanger 59, energization to the ceramic heater 78 provided in the heat exchanger 59 is started, and cleaning is performed. Heat the water. Then, the flow rate adjusting valve 57 is controlled so as to become a predetermined flow rate value set by the adjusting unit 74 of the remote controller 70, and a hot water temperature signal from the hot water thermistor 62 is read to the ceramic heater 78 so as to reach a predetermined hot water temperature. The energization amount of is variable. 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 the flow path on the nozzle unit 63 side. Hot water is guided to the washing nozzle 64. At the same time, the air pump 66 is driven to mix air into the washing water.
[0072]
  The cleaning water whose flow rate is adjusted by the flow rate control valve 57 and heated to an appropriate temperature by the heat exchanger 59 is mixed with air from the air pump 66 through the air pipe 67, and then reaches the nozzle unit 63, where the cleaning nozzle 64 is discharged to the local body part. Since the cleaning jet here is the above-described aerated jet, the cleaning is performed by swinging a relatively wide range of the human body part. And the flow rate without impairing the cleaning effect and the user's feeling compared with the conventional case of cleaning with only warm water due to the improvement of the ejection speed at the nozzle part 83 due to the mixing of air and the effect of repelling the mixed air Can be cleaned with less than half.
[0073]
  In addition, the use of the instantaneous heat exchanger 59 eliminates heat dissipation loss during hot water storage and halves the flow of washing water compared to conventional hot water storage heating means. The amount used can be reduced. Furthermore, since the cleaning water is supplied to the toilet cleaning nozzle 87 side after the instruction to start cleaning is supplied until the appropriate temperature warm water is supplied, when the cleaning water actually hits the anus, the appropriate temperature hot water is jetted, Prevents the loss of comfort.
[0074]
  Further, since residual chlorine, which is contained in tap water and is also said to cause anal pruritus, is removed by the filter 56, it is considered that even if washing is performed for a long time, it does not adversely affect the local body part. In addition, in the conventional hot water storage type human body local washing device, the hot water is heated and stored in the hot water tank, so that various bacteria are propagated in the hot water tank by removing residual chlorine, and in the human body local area. Although there is a possibility of adverse effects, there is no such concern because the instantaneous heat exchanger 59 is employed here. Here, the filter 56 is configured using activated carbon, but other configurations such as ion exchange resin, chemicals such as sodium thiosulfate and calcium sulfite, tungsten, titanium, and molybdenum based catalysts are also conceivable.
[0075]
  Next, the operation during stool induction cleaning will be described.
[0076]
  Next, the operation at the time of stool induction cleaning will be described with reference to FIG. FIG. 14 is a time chart showing the operations of the original solenoid valve 55, the flow rate adjusting valve 57, and the air pump 66 when the user presses the stool induction switch 75 of the remote controller 70 and the start of stool induction cleaning 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 substantially the same as in normal cleaning. The operation after 64 protrusions is mainly shown.
[0077]
  In FIG. 14, after the instruction to start cleaning is given, the cleaning nozzle 64 protrudes, and when the flow path on the nozzle unit 63 side is opened by the three-way valve 86, the stool control operation control unit 76 provided in the controller 77 is After maintaining that state for a predetermined time, the air pump 49 is turned on and off at a predetermined voltage for a predetermined period. Further, when the air pump 66 is ON, the flow rate adjustment valve 57 is held at a predetermined opening, and the flow rate adjustment valve 57 is greatly opened in synchronization with the OFF of the air pump 66. Here, when the air pump 66 is ON, the flow rate of the cleaning water is the same as that during normal cleaning, and when it is OFF, the flow rate control valve is set so that the flow rate of the cleaning water is approximately twice that during normal cleaning. An opening degree of 57 is set. The applied voltage is set so that the amount of air that the air pump 66 feeds into the cleaning water is about 80% of that during normal cleaning. However, the opening degree of the flow rate adjusting valve 57 immediately after the flow path on the nozzle unit 63 side is opened by the three-way valve 86 is set to be equal to or slightly less than that during normal cleaning. This is a consideration for facilitating the user's cleaning position adjustment by ejecting a direct jet flow with a small flow rate.
[0078]
  In addition, when the air-entrained jet is ejected, that is, when the air pump 66 is turned on, the controller 77 varies the amount of current supplied to the ceramic heater 78 and is relatively warm (37 ° C.) hot water. To supply. Then, immediately before switching to the direct jet flow, that is, immediately before turning off the air pump 66, the energization amount to the ceramic heater 78 is increased, and control is performed so that the hot water temperature at the start of direct jet flow is increased (40 ° C.). .
[0079]
  As a result, the aeration jet in the fourth embodiment is set to have warm water that is less irritating than normal washing and that is warm, and that softly stimulates the anus with soft water flow, It is effective to relax and promote anal relaxation. Furthermore, the direct jet that stopped mixing air is a relatively strong concentrated jet because the flow rate has increased significantly, and it has leaked into the anus.Suitable forYes. In addition, since warm hot water is jetted at the start of jetting of the direct jet flow, there is also an effect of stimulating the anus and inducing convenience.
[0080]
  In addition, the repetition period of the air-mixed jet and the direct jet in Example 4 was set to an 8-second period of 2 seconds for the air-mixed jet and 6 seconds for the direct jet. As a result, since the abruptly concentrated jet hits the anus whose relaxation has been promoted by the aeration jet, the wash 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, long-lasting washing promotes relaxation of the anus, making it easier for the washing water to leak into the anus and continuously inducing a bowel reflex to further activate peristaltic movement of the intestinal tract. it can. Further, since the instantaneous heat exchanger 59 has a small heat capacity, it is possible to quickly change the temperature of the hot water to be supplied, and to give a temperature stimulus to the anus.
[0081]
  It should be noted that the flow rate of the cleaning water greatly changes during the direct jet discharge in the fourth embodiment, so that the controller 77 greatly changes the energization amount of the ceramic heater 78 so that the cleaning water with the appropriate temperature can be obtained. To control. 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. .
[0082]
  (Example 5)
  A fifth embodiment of the present invention will be described. Since this embodiment 5 has the same configuration and operation during normal cleaning as the embodiment 4, the description thereof will be omitted, and constipation-induced cleaning with a partially different operation will be described with reference to FIG.
[0083]
  FIG. 15 is a time chart showing the operations of the original solenoid valve 55, the flow rate adjustment valve 57, and the air pump 66 when the user presses the stool-inducing switch 75 of the remote controller 70 and the stool-inducing cleaning is started.
[0084]
  In FIG. 15, when an instruction to start cleaning is given, the controller 77 opens the flow path on the toilet cleaning nozzle 87 side, opens the original electromagnetic valve 55, and opens the flow rate adjustment valve 57 to a predetermined opening. Further, when the temperature of the cleaning water reaches a predetermined value, after the cleaning nozzle 45 is discharged, the flow path on the nozzle unit 63 side is opened and the state is maintained for a predetermined time. Then, after a predetermined time has elapsed, the air pump 66 is started at a predetermined voltage. Here, the stipulation inducing operation control unit 76 provided in the controller 77 controls the flow rate adjustment valve 57 so that the amount of washing water increases or decreases in a predetermined cycle. The opening is adjusted in two steps. Further, in synchronization with the opening degree adjustment of the flow rate control valve 39, the voltage applied to the air pump 66 is similarly varied in two stages. As apparent from FIG. 14, the voltage applied to the air pump 66 is set high when the opening degree of the flow control valve 57 is small, and conversely, the voltage applied to the air pump 66 is set low when the opening degree of the flow control valve 57 is large. It is. Here, when the opening degree of the flow rate adjusting 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, and the voltage applied to the air pump 66 is the amount of air fed in during the normal washing. It is set to be about 80% of the value. Further, when the opening of the flow control valve 57 is large, the opening is set so that the flow rate of the washing water is about 1.5 times that during normal washing, and the voltage applied to the air pump 66 is determined by the amount of air supplied. It is set to be about 20% of the value during normal cleaning.
[0085]
  By these operations, since the flow rate of the cleaning jet ejected from the cleaning nozzle 64 changes at a predetermined cycle, the user's sensation is also greatly changed, 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 aerated jet of Example 3 is obtained, and the anus is softly stimulated with a soft water flow compared to the time of normal washing, and the anal relaxation is promoted. It is effective. Further, when the opening degree of the flow rate control valve 57 is large, the ratio of the air mixed in the washing water becomes considerably smaller than that when the opening degree is small, so that the direct flow of the third embodiment is slightly thicker. It becomes a direct jet of shape. This is because, as the amount of air decreases, the repelling action is also greatly reduced, so that it does not diffuse as widely as an aerated jet. However, when air is mixed even in a small amount, the apparent volume of the cleaning water increases, and the flow rate of the cleaning water ejected from the nozzle port 83 is improved by the corresponding amount. Therefore, the user feels strongly that a small amount of air is mixed if the flow rate of the washing water is the same, and the feeling is improved by slightly thickening the washing jet. Therefore, even if the flow rate of the washing water is reduced, it is sufficient to leak into the anus and it is possible to obtain a jet having an excellent feeling.
[0086]
  In Example 5 as well, the repetition cycle of the air-mixed jet and the direct jet was set to an 8-second cycle of the air-mixed jet 2 seconds and the direct jet 6 seconds. As a result, the anus whose relaxation has been promoted by the aeration jet is hit by a concentrated jet with a small amount of air inadvertently. Is done. In addition, in the fourth embodiment, although the concentrated jet is a small amount, air is mixed therein, so that the bodily sensation is excellent and the washing water is infiltrated into the anus with a small amount of washing water as compared with the case where air is not mixed. Can do.
[0087]
【The invention's effect】
  As described above, according to the human body local cleaning device of the present invention, the following effects can be obtained.
[0088]
  (1) By appropriately controlling the heating means and the water supply control means according to the setting of the convenience-inducing cleaning setting means, it is possible to clean the human body part with a cleaning jet suitable for inducing the convenience, resulting in the user's convenience Can be actively induced to assist with comfortable defecation. Further, since the normal cleaning setting means and the stool-inducing cleaning setting means are provided, it is possible to use different cleaning jets depending on the situation, and the user convenience is improved.Then, when the convenience-inducing cleaning setting means is selected and set, the controller starts the cleaning by setting the amount of water in the intrusion jet immediately after the start of cleaning to be smaller than the intrusion jet to be jetted after the second switching of the jet flow. It can prevent anal tension that sometimes occurs and promote anal relaxation more.
[0089]
  (2) Since the relationship between the washing dynamic pressure of the jet is relaxed jet <normal jet <relaxed jet, the relaxing effect of the relaxed jet is further enhanced, and the infiltrating jet is likely to enter the anus. In addition, the change in the washing dynamic pressure when switching from the relaxed jet to the infiltrating jet is increased, effectively stimulating the anus and enhancing the stool induction effect.
[0090]
  (3) The jet switching means is configured to be able to change the form of the relaxation jet and the intrusion jet, and the relationship between the cleaning areas is relaxation jet> infiltration jet, so that the relaxation jet that can wash a large area has an appropriate stimulus to the anus In addition, the relaxation effect is further improved, and the intruding jet hits a small area, so that it can easily enter the anus, and the user's convenience can be more effectively induced.
[0091]
  (4) Since the duration of the relaxation jet and the intrusion jet within the repetition cycle is set separately, it is possible to flexibly respond to the duration of each jet where the degree of relaxation of the anus and the degree of penetration of washing water have a great dependency In addition, the relaxation of the anus can be effectively promoted, and the probability of water intrusion into the anus can be improved.
[0092]
  (5) By setting the duration of the relaxation jet within the repetition period to 2 seconds or more, the anal relaxation of the user can be further promoted, and as a result, the user's convenience can be effectively induced.
[0093]
  (6) Irregularly changing the duration of at least one of the relaxation jet or the intruding jet within the repetition cycle eliminates the monotonous feeling and applies the intruding jet unexpectedly, so that the washing water into the anus The penetration probability can be improved, and the user's convenience can be induced more effectively.
[0094]
  (7) When the stool-inducing cleaning setting means is selected and set, by starting cleaning with a relaxed jet, it promotes anal relaxation immediately after the start of cleaning and prevents anal tension caused by suddenly strong jets. it can.
[0095]
  (8) If the convenience-inducing cleaning setting means is selected and set, the cleaning area at the start of cleaning becomes narrow by changing the jet form at the start of cleaning to an intrusion jet. This makes it easier to improve the probability that washing water will leak into the anus.
[0096]
  (9) The heating means is an instantaneous heat exchanger, and the temperature of the wash water supplied in conjunction with the switching time between the relaxation jet and the intrusion jet is variably controlled, so that the stimulation pressure generated when switching between the relaxation jet and the intrusion jet is reduced. In addition to the change, the anus can be stimulated by the temperature change of the washing water, and the user's convenience can be more effectively induced.
