Abstract

PROBLEM TO BE SOLVED: To provide the sanitary washing toilet seat device that allows moisture to be easily retained in a localized area and enables pre-washing with less stimulus to the localized area.SOLUTION: The sanitary washing toilet seat device comprises: a tank for storing water; a heater that generates water vapor by heating the water in the tank; and an ejecting portion that ejects the water vapor generated in the tank so as to reach the localized part of a human body seated on a toilet seat. Water droplets liquefied by application of the water vapor to the localized area (an anal portion) are very difficult to flow down because the water droplets are very small. As a result, the sanitary washing toilet seat device makes it easy for moisture to remain in the localized area, and can suppress attachment of dirt to the anal portion during defecation. In addition, the sanitary washing toilet seat device has a very low pressure so that stimulus of the sanitary washing toilet seat device can be reduced since the application of steam to the localized part (the anal portion) is performed only by an updraft of heated water vapor.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a sanitary wash toilet seat device.

  Heretofore, as this type of sanitary washing toilet seat device, there has been proposed a device that sprays washing water from the washing nozzle toward the local area from the time when the seating of the user on the toilet seat is detected until defecation or urination (See, for example, Patent Document 1). In this sanitary lavage toilet seat device, it is possible to reduce the friction between the feces and the epidermis of the anus at the time of defecation by relieving water around the local area before defecation and the like, and to relieve pain at the time of defecation.

  Moreover, what spray-sprays mist towards the local part of a human body and performs local washing | cleaning by mist is also proposed (for example, refer patent document 2). In this sanitary washing toilet seat device, even if it is a patient who feels pain in the usual shower water flow, it is comfortable and gentle mist washing by spray-spraying granular mist finer than the shower water flow from the normal washing nozzle You can feel it.

Unexamined-Japanese-Patent No. 2000-144849 JP, 2006-274603, A

  However, according to the technique described in Patent Document 1, since the washing water is sprayed to the anus portion by a normal shower water flow, it is easy for the acupuncture patient to feel pain. In addition, since the droplets of water are large, they are likely to flow off and it is difficult for water to stay in the anus. For this reason, the anus part becomes easy to dry, and there is a possibility that dirt may be easily attached or the flexibility of the anus part may be reduced. On the other hand, in the technique described in Patent Document 2, although stimulation to the anal region is weaker than normal shower water flow, it may be considered that even mild stimulation may cause pain for severe decubitus patients.

  The sanitary washing toilet seat device of the present invention is mainly intended to provide a sanitary washing toilet seat device in which water can easily be retained for the local area and pre-washing can be performed with less irritation for the local area.

  The sanitary washing toilet seat device of the present invention adopts the following means in order to achieve the above-mentioned main object.

  The sanitary washing toilet seat device of the present invention includes a water vapor generating unit that generates water vapor and applies it to a local part (anus part) of the human body. Water droplets liquefied by the application of water vapor to the local area (anus) are hard to flow off because the particles are very small. As a result, the water can be easily retained locally, and it is possible to suppress the adhesion of the filth to the anus at the time of defecation. Also, the application of water vapor to the local area (the anal region) is performed only by the rising air flow of the heated water vapor, so the pressure is very low and the stimulation to the local area can be lessened.

  In the sanitary washing toilet seat apparatus of the present invention, the arrival position of the water vapor jetted from the jetting unit may be changeable. In this way, the generated water vapor can reach the target position regardless of the user's physical size and sitting position.

  A mode for carrying out the present invention will be described.

  FIG. 1 is an external view showing the external appearance of the sanitary washing toilet seat device 10 and the toilet bowl 1 of the present embodiment, and FIG. 2 is a configuration diagram showing an outline of the configuration of the toilet seat device main body 20. The sanitary washing toilet seat device 10 of the present embodiment is installed and used on the upper surface of the toilet bowl 1, and similar to the toilet seat device main body 20, the toilet seat 12 supported to be able to open and close with respect to the toilet seat device main body 20, and the toilet seat 12. The toilet seat 14 is provided with a toilet lid 14 supported so as to be able to open and close with respect to the toilet seat device main body 20, and an operation panel 16 capable of various operations.

  For example, as shown in FIG. 2, the operation panel 16 applies a water vapor droplet to the local area to pre-clean the local area by a water vapor cleaning switch 16a, or to eject cleaning water from a shower water flow to clean the hips. Foot washing switch 16b, bidet washing switch 16c used as a bidet, washing position adjustment switch 16d for adjusting each washing position of steam washing, butt washing and bidet washing, adjusting washing strength of butt washing or bidet washing There are provided a cleaning strength adjustment switch 16e for the purpose, a stop switch 16f for stopping the steam cleaning, the hip cleaning or the bidet cleaning. The cleaning position adjustment switch 16 d is configured to include a front switch for moving the cleaning position forward, and a post switch for moving the cleaning position back.

  As shown in FIG. 2, the toilet seat device main body 20 is provided in the flush water solenoid valve 22 which controls the supply of water to the flush water flow path 24 connected to the water supply pipe (water pipe) 2 and the flush water flow path 24 A cleaning unit 30 having a heat exchange unit 26, a pulsation pump 32, a switching valve 34, a plurality of local cleaning nozzles 36 and 38, and a steam generation unit 40, and a control device 50 for controlling the entire apparatus.

  The heat exchange unit 26 is a so-called instantaneous heat exchanger having a hot water heater 28 that instantaneously converts the water flowing through the washing water flow path 24 into hot water (for example, about 35 ° C. to 45 ° C.). The one with rated power consumption of 1200 W is used.

  The switching valve 34 adjusts the strength of the cleaning as required. Which one of the plurality of local cleaning nozzles 36 and 38 and the water vapor generation unit 40 ejects the water in the cleaning water flow path 24 downstream of the pulsation pump 32 It is what changes. In the present embodiment, the plurality of local cleaning nozzles 36 and 38 are configured by a nozzle 36 for cleaning the back and a nozzle 38 for the bidet.

  FIG. 3 is a block diagram showing an outline of the configuration of the water vapor generation unit 40. As shown in FIG. In addition, the partial view shown in the upper right part of FIG. 3 is a partial view when the spout 46a of the spouting portion 46 is viewed from the front. As shown in FIG. 3, the water vapor generation unit 40 is provided in a tank 41 for storing water, a water supply solenoid valve 42 for opening and closing the inlet of the tank 41 connected to the switching valve 34, and is stored near the bottom of the tank 41. The heater includes a heater 44 for boiling water to generate steam, a jet unit 46 for jetting the generated steam, and a throttle device 47 for changing the diameter of the jet port 46 a of the jet unit 46. The water (warm water) heated through the heat exchange unit 26 is supplied to the tank 41 through the switching valve 34, and the supplied hot water is heated by the heater 44. Boil the hot water quickly to generate water vapor. In the present embodiment, the tank 41 has a capacity of about 50 to 100 ml, and the heater 44 has a rated power consumption of 1200 W. Here, when heating 50 ml of water (specific heat is 1 Kcal / (Kg · ° C., density is 1 kg / L) supplied into the tank 41 by the heater 44 of 1200 W, the water is raised from 40 ° C. to 100 ° C. The time required for warming is about 10 seconds. Therefore, it is possible to generate water vapor about 10 seconds after the heating by the heater 44 is started. The bottom of the tank 41 is provided with a discharge port (not shown) which can be opened and closed. When the steam cleaning is completed, the water remaining in the tank 41 can be discharged by opening the discharge port. It has become.

  The angle of the jet 46 a is determined so that the jetted water reaches the local part (anus part) of the person seated on the toilet seat 12. Specifically, since the heated water vapor moves upward slightly more than air, the water jet is directed toward the toilet 1 side (horizontal side) slightly more than the direction toward the local part of the seated person The spouting angle of the spout 46a is determined so as to be spouted.

  The throttling device 47 includes a throttling plate 48 having a throttling opening 48a having substantially the same diameter as the spout 46a of the spouting portion 46, and a throttling motor 49 to which a rotation shaft 49a is connected at a position eccentric from the center of the throttling plate 48. Prepare. As shown in FIG. 4A, the diaphragm device 47 rotates the diaphragm plate 48 by the diaphragm motor 49 so that the diaphragm opening 48a of the diaphragm plate 48 substantially overlaps with the jet port 46a of the jet portion 46. Is almost fully open. As a result, as shown in FIG. 4B, the water vapor generated in the tank 41 is ejected from the ejection portion 46 at a relatively low ejection velocity, and moves upward in the direction of gravity without advancing too much in the ejection direction. Eventually, the arrival position P1 is reached. Further, as shown in FIG. 5A, the diaphragm device 47 uses the diaphragm motor 49 so as to close a part of the jet port 46a of the jet portion 46 with a plate surface around the diaphragm opening 48a of the diaphragm plate 48. By rotating, the diameter of the spout 46a is narrowed. As a result, as shown in FIG. 5B, the water vapor generated in the tank 41 is jetted from the jet portion 46 at a relatively high jet velocity, and moves upward in the gravity direction while advancing far in the jet direction. Finally, an arrival position P2 farther than the arrival position P1 is reached. As described above, by changing the diameter of the jet nozzle 46 a by the expansion device 47, it is possible to change the jet velocity of the water vapor and change the reaching position of the water vapor.

  In the steam generating unit 40, when steam is jetted from the jetting unit 46, the jetted steam moves upward in the direction of gravity and touches the surrounding air to be cooled, resulting in steam mixed with water droplets and eventually becomes the toilet seat 12. It reaches and adheres to the local part (anus part) of the person who seated. The water droplets adhering to the anus are hard to flow off because they are very small water droplets (about several μs). For this reason, by applying water vapor to the anus before defecation, it is possible to suppress the adhesion of the dirt at the time of defecation, and the excellent effect as the pre-washing is exhibited. In addition, the application of water vapor to the anus is only by the rising air flow of water vapor, so the pressure is small and it is possible to clean the patient without pain even in patients with epilepsy. Furthermore, since the water droplets adhering to the anal region are heated by the heater 44, the bactericidal effect is high and the cleanliness can be maintained. In addition, in a normal shower cleaning (cleaning by a nozzle), sebum is also blown away by a strong water flow and easily dried, and dirt may adhere and the flexibility of the anus portion may be reduced, whereas water vapor may In the cleansing, it is possible to apply a water droplet to the anal area holding sebum. In addition, blood flow is promoted in the anal region due to the thermal effect of water vapor, and warm-up of the anal sphincter is also performed, and an anal region is improved in flexibility to suppress an anal at the time of defecation.

  The control device 50 is configured as a microcomputer centering on the CPU 52, and includes a ROM 54, a RAM 56, an input / output port (not shown), etc. in addition to the CPU 52. The control device 50 receives switch signals from the switches 16a to 16f of the operation panel 16 and detection signals from the seating sensor 18 for detecting the seating of a person on the toilet seat 12 via the input port. From the control device 50, a drive signal to the water shutoff solenoid valve 22, a drive signal to the hot water heater 28, a drive signal to the pulsation pump 32, a drive signal to the switching valve 34, a drive signal to the heater 44, a diaphragm motor The drive signal to 49 and the like are output through the output port.

  Next, the operation of the sanitary washing toilet seat apparatus 10 thus configured, particularly, the operation regarding steam cleaning will be described. FIG. 6 is a flowchart showing an example of the steam cleaning control routine. This routine is executed when the steam cleaning switch 16a is turned on in a state where the seating sensor 18 detects that a person is seated.

  When the steam cleaning control routine is executed, the CPU 52 of the control device 50 first turns on the hot water heater 28 (S100). Subsequently, the switching valve 34 is driven to connect the flush water flow path 24 and the tank 41 of the steam generation unit 40 (S110), and the water supply solenoid valve 42 is opened for a predetermined time to steam the water in the flush water flow path 24. It supplies to the tank 41 of the unit 40 (S120). Since the water in the wash water flow path 24 is heated by the hot water heater 28, the hot water is supplied to the tank 41.

  When hot water is supplied to the tank 41, the CPU 52 turns off the hot water heater 28 (S130) and turns on the heating heater 44 (S140). As a result, the water (warm water) stored in the tank 41 is heated by the heater 44 and becomes water vapor, and the water vapor is ejected from the ejection part 46 to start the water vapor cleaning. As described above, when 50 ml of hot water at 40 ° C. is supplied to the tank 41, water vapor is generated in about 10 seconds after the heater 44 is turned on by heating the warm water with the heater 44 of 1200 W. be able to.

  Next, the CPU 52 determines whether the front switch of the cleaning position adjustment switch 16d is turned on (S150). If it is determined that the front switch is turned on, the diameter of the jet port 46a is changed to the enlarged side. The drive control of the motor 49 is performed (S160), and when it is determined that the front switch is not turned on, the process of S160 is skipped. Further, the CPU 52 determines whether the back switch of the cleaning position adjustment switch 16d is turned on (S170), and if it is determined that the back switch is turned on, the diameter of the jet port 46a is changed to the reduction side. If it is determined that the rear switch is not turned on, the process of S180 is skipped. Then, it is determined whether the stop switch 16f is turned on (S190). If it is determined that the stop switch 16f is turned on, the heater 44 is turned off (S200), and the steam cleaning control routine is ended.

  The sanitary washing toilet seat device 10 of the present embodiment described above includes the water vapor generation unit 40 that generates water vapor and applies the generated water vapor to a local part (anus part) of a person seated on the toilet seat 12. Water droplets liquefied by the application of water vapor to the local area (anus) are hard to flow off because the particles are very small. As a result, the water can be easily retained locally, and it is possible to suppress the adhesion of the filth to the anus at the time of defecation. In addition, the application of water vapor to the local area (the anal region) is performed only by the updraft of the water vapor, so the pressure is very low and the stimulation to the local area can be lessened. It is also preferable that the sanitary washing toilet seat device 10 apply water vapor (water droplets) to the anus after defecation by the water vapor generation unit 40. That is, it is also conceivable that when the toilet 36 is used to wash the body after defecation by using the nozzle 36, the dirt adhering to the anus portion is spattered and the spattered dirt is adhered to the back side of the toilet seat 12. However, according to the method of applying water vapor (water droplets) by the water vapor generation unit 40, since the pressure is very low, it is possible to clean the back without spattering dirt.

  In addition, the sanitary washing toilet seat device 10 of the present embodiment includes the expansion device 47 that changes the diameter of the steam outlet 46 a. Thereby, the jet velocity of water vapor can be changed to change the reaching position. That is, the sanitary washing toilet seat device 10 can change the washing position at the time of steam washing to a desired position.

  Furthermore, the sanitary washing toilet seat device 10 of the present embodiment supplies the warm water having passed through the heat exchange unit 26 (hot water heater 28) into the tank 41 of the steam generation unit 40, and the warm water supplied into the tank 41 as the heater. Since the steam is generated by heating at 44, the steam can be efficiently generated by the warm water heater 28 and the heater 44.

  In the present embodiment, the steam generation unit 40 includes the expansion device 47 for changing the cleaning position of the steam cleaning. However, as shown in the water vapor generation unit 140 according to another embodiment of FIG. 7, a fan 147 capable of changing the cleaning position by blowing air toward the water vapor jetted from the jet unit 46 instead of the expansion device 47. May be provided. The fan 147 is installed at the top of the ejection portion 46, and can blow air from the rear to the front of the toilet bowl (from the left to the right in the figure). When the rotation of the fan 147 is stopped, the water vapor jetted from the jetting unit 46 moves upward in the direction of gravity without advancing in the jetting direction as shown in FIG. 8A, and eventually reaches the reaching position P1. To reach. On the other hand, when the fan 147 is rotating, the water vapor ejected from the ejection portion 46 is carried by the wind from the fan 147 and travels far in the ejection direction, as shown in FIG. It moves upward and eventually reaches a reaching position P2 that is farther than the reaching position P1. Thus, the arrival position of the water vapor can be changed by changing the presence or absence of the air from the fan 147 or the air volume. In the water vapor generation unit 140 provided with such a fan 147, the amount of air touching the water vapor can be increased and the temperature of the water vapor can be decreased by increasing the air volume of the fan 147. That is, by adjusting the air volume of the fan 147, it is possible to adjust the temperature of the water vapor (water droplets) applied to the local part (anus part) of the person to a desired temperature.

  In the present embodiment, the water vapor generation unit 40 generates water vapor by directly heating the water (hot water) supplied to the tank 41 by the heater 44. However, the water vapor generation according to the other embodiment of FIG. As shown in the unit 240, a heat storage material 245 made of metal such as aluminum is provided at the bottom of the tank 41, and the heater 44 is driven to control the heat storage material 245 to be heated. The feed water solenoid valve 42 may be driven and controlled so as to supply (hot water). In addition, as a heating timing of the thermal storage material 245 by the heater 44, it is detected by the entrance detection sensor (not shown) that the timing that the user seated on the toilet seat 12 was detected by the seating sensor 18 and that the user entered the toilet Can be illustrated. As described above, the heat storage material 245 is first heated, and then water (hot water) is supplied to the heat storage material 245, whereby the waiting time until the generation of water vapor can be shortened. It is desirable that the supply of water to the heat storage material 245 be performed little by little to such an extent that water vapor (warm water) is immediately generated when the heat storage material 245 is touched with water (warm water).

  In the present embodiment, the steam cleaning is performed when the steam cleaning switch 16a is turned on in a state in which the seating sensor 18 detects that the user is seated on the toilet seat 12, but the invention is limited thereto Instead, the steam cleaning may be performed only on the condition that the seating sensor 18 detects that the user is seated on the toilet seat 12. In this case, the steam cleaning switch 16a may be omitted.

  In addition to the water vapor generation unit 40, a spray device (for example, an ultrasonic spray device) may be provided, and the steam sprayed from the water vapor generation unit 40 may be mixed with the mist sprayed by the spray device. By adjusting the amount of mist sprayed from the spray device, it is possible to adjust the temperature of water vapor (water droplets) applied to a local part (anal part) of a person to a desired temperature.
