Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a private parts cleaning device for cleaning private parts of a human body.

[Background Art] Conventionally, as shown in FIG. 4, this type of private parts cleaning device is a closed type hot water device that is equipped with a heating means 1, and water is supplied from the bottom, and warm water is supplied from the top to the cleaning nozzle 2. A pressurized water supply means 4 that includes a tank 3 and supplies water under pressure to the hot water tank 3
(Generally, the pressure of tap water is used, but a pump may also be used to generate the pressure), and the operation of the pressurized water supply means 4 is controlled by operating the operation switch (controlled by the solenoid valve 25). The jetting of hot water from the cleaning nozzle 2 was controlled by the cleaning nozzle 2. However, in such a conventional example, one cleaning nozzle 2 is used for both anal cleaning and bidet cleaning, which poses a sanitary problem.
Therefore, as shown in FIG.
Solenoid valves 7a and 7b for flow path switching are provided in the hot water supply path that supplies hot water to the cleaning nozzles 2a and 2b from which hot water is spouted by opening one of the solenoid valves 7a and 7b as necessary. I found something to choose from. By the way, when the solenoid valves 7a and 7b for flow path switching are provided in this way, the solenoid valve 25 and the solenoid valves 7a and 7b are closed simultaneously at the end of the cleaning operation, so that the pressure in the tank 3 is increased. This caused a problem in that the stress concentration part of the hot water tank 3 was destroyed and water leakage was likely to occur. That is,
In this conventional example, the solenoid valve 25 for controlling the pressurized water supply of the pressurized water supply means 4 and the solenoid valve 7a or 7b for switching the flow path were closed at approximately the same time. The solenoid valve 7a or 7b is closed while pressure is still applied to the hot water tank 3, and a water hammer effect occurs due to the kinetic energy of the water, and a high residual pressure is constantly applied to the hot water tank 3. As a result, the stress concentration part of the hot water tank 3 is destroyed and water leakage is likely to occur.

[Object of the Invention] The present invention has been made in view of the above-mentioned problems, and its object is to provide a private part cleaning device in which water leakage from a hot water tank is less likely to occur.

[Disclosure of the Invention] (Structure) Fig. 1 shows the structure of the present invention, which is a sealed device that is equipped with a heating means 1, water is supplied from the lower part, and warm water is supplied from the upper part to the cleaning nozzles 2a and 2b. Pressurized water supply means 4 consisting of a type hot water tank 3 and a submersible pump 4a that supplies water under pressure to the hot water tank 3
and a cleaning control means 6 which controls the pressurized water supply means 4 with the operation switch 5 to control the spouting of hot water from the cleaning nozzles 2a and 2b. Nozzle 2
Solenoid valves 7a and 7b for flow switching are provided in the hot water supply passages that supply hot water to the hot water supply channels a and 2b, respectively, and the closing time of the solenoid valves 7a and 7b is delayed from the time when the pressurized water supply means 4 stops. hot water tank 3
This system is equipped with a residual pressure removing means 8 for removing the residual pressure of the hot water tank 3, and can prevent water hammer force from being applied to the hot water tank 3 or from constantly applying large pressure, so that the stress concentration area of the hot water tank 3 can be prevented. This prevents damage to the hot water tank 3, making it difficult for water leakage to occur.
Since the strength of the hot water tank 3 can be lowered, the material cost can be reduced and the cost can be reduced, and the hot water tank 3 can be easily designed.

(Embodiment) FIGS. 2 to 4 show an embodiment of the present invention, in which a private parts cleaning device is provided with a hot water tank 3 equipped with a heater 1a on one side of a toilet bowl 10. Solenoid valves 7a, 7b on the top of 3
Cleaning nozzles 2a and 2b are provided on both sides of the toilet bowl 10 so as to be able to swing freely, and are communicated through the
The cleaning nozzle 2a or 2b is rotated to a predetermined position by the swing motors 13a and 13b when the clean (for anal cleaning) operation switch 5a or the beauty (for bidet cleaning) operation switch 5c is pressed, and then drying is performed. Until the operation switch 5b is pressed, the submersible pump 4a provided in the wash water tank 9 operates, and the pump 4a adjusts the water pressure of the water pressurized to the lower part of the hot water tank 3. The private parts of the human body are washed by jetting hot water from a washing nozzle 2a or 2b. Here, the water pressure level of the hot water spouted from the cleaning nozzles 2a, 2b (the operating level of the pump 4a, which is the pressurized water supply means 4) is determined by the level setting switch 15.
It is set in a, 15b,
Each time you press the “high” level setting switch 15a,
The water pressure level increases by one step, and each time the "low" level setting switch 15b is pressed, the water pressure level decreases by one step. The water pressure level set by the level setting switches 15a and 15b is displayed on the display means formed by the LEDs 16a to 16g (for example, one of the LEDs 16a to 16b corresponding to the set level lights up).
At the same time, it is stored in the memory section of the cleaning control means 6, which is an arithmetic circuit using a CPU. Further, when the drying operation switch 5b is pressed, a drying means (not shown) consisting of a heater and a blower fan is driven to dry the washed private part. By the way, the toilet seat 10a rotatably attached to the toilet bowl 10
A toilet seat switch (not shown) that is activated when a predetermined weight is applied is provided on the pivot portion of the toilet seat 10a, and when the user sits on the toilet seat 10a, the toilet seat switch is turned on and the private parts cleaning device becomes operational. An operation indicator lamp 17 is turned on to indicate that it is set and ready for operation, and at the same time, a deodorizing means (not shown) is driven. Next, when drying is completed and the user leaves the toilet seat 10a, the toilet seat switch is turned off, the operation of the drying means is stopped, and the cleaning operation is completed. In the embodiment, the LEDs 16a to 16g of the display means also serve as a display of the air pressure level of the hot drying air preset in the memory section of the cleaning control means 6. The wind pressure level is set using the level setting switches 15a and 15b when the drying operation switch 5b is pressed to start the drying operation. The operation unit 20 with a lid also includes means for setting hot water temperature and hot air temperature, which are not operated during normal cleaning operations, and turning on the heater 1a in the hot water tank 3.
A switch-off means is provided. Note that a control circuit 22 such as the cleaning control means 6 and the residual pressure removal means 8 formed using a CPU or a sequence control LSI is housed in the toilet main body housing 21.

The operation of the embodiment will be described below. now,
When the user sits on the toilet seat 10a, the toilet seat switch is turned on and the private parts cleaning device is set in an operable state. In this state, when the clean or beauty operation switch 5a or 5c is pressed, the cleaning control means 6 operates the pump 4a, which is the pressurized water supply means 4, and the predetermined solenoid valve 7a or 7b for a short period of time (for example, for 1 second). is driven, hot water is supplied into the pipe of the cleaning nozzle 2a or 2b, and cold water remaining in the pipe of the cleaning nozzle 2a or 2b is jetted out and removed. After that, the clean operation switch 5a is pressed and the cleaning nozzle 2a is activated.
A case will be explained in which hot water is spouted from. With the cold water removed as described above, the driving of the pump 4a and the solenoid valve 7a is temporarily stopped, and the swing motor 13a that swings the cleaning nozzle 2a to a predetermined position is driven, and the cleaning nozzle 2a is moved to a predetermined position. Moved to position and stopped. With the cleaning nozzle 2a set in the predetermined position in this way, the pump 4a and the solenoid valve 7a are driven again, and hot water is force-fed to the cleaning nozzle 2a through the open solenoid valve 7a, and Hot water at a predetermined water pressure level is jetted out from a nozzle hole formed in the body to cleanse the private part (in this case, the anus). Next, when the cleaning operation is completed and the drying operation switch 5b, which also serves as the operation switch for stopping the cleaning, is pressed, the driving of the pump 4a is immediately stopped, and the residual pressure removing means 8 causes a constant pressure to be maintained from the time when the pump 4a is stopped. After a time delay, the driving of the solenoid valve 7a is stopped, and when the residual pressure in the hot water tank 3 is removed, the solenoid valve 2a is closed. Therefore, hot water tank 3
It is possible to prevent water hammer force from being applied to the water tank and to prevent large pressure from being constantly applied to the hot water tank 3, thereby preventing the stress concentration part of the hot water tank 3 from being destroyed and making it difficult for water leakage to occur. Furthermore, in this case, the strength of the hot water tank 3 can be lowered, so that material costs can be reduced and costs can be reduced, and the hot water tank 3 can be designed easily. Next, when the spouting of hot water ends, the swing motor 13a is reversed to return the cleaning nozzle 2a to its original storage position, and at the same time, the heater and blower fan of the drying means are driven to dry the cleaned private parts. will be carried out. When the private parts washed in this way are dried and the user stands up, the toilet seat switch is turned off, the completion of use is detected, and the drying means is turned off after a certain period of time (for example, 3
minutes later), power supply to other means is stopped, and the private parts cleaning device is placed in a standby state until the toilet seat switch is turned on next time. At this time, it goes without saying that the operation indicator lamp 17 is turned off and the deodorizing means is stopped. Note that the washing and drying may be interrupted by pressing the operation switches 5a to 5c again, or a separate operation switch for stopping may be provided.

[Effects of the Invention] As described above, the present invention provides a closed type hot water tank that is equipped with a heating means and is supplied with water from the lower part and hot water is supplied to the cleaning nozzle from the upper part, and a hot water tank that is pressurized with water. In a private area cleaning device comprising a pressurized water supply means for supplying water, and a cleaning control means for controlling the pressurized water supply means by operating an operation switch and controlling the spouting of hot water from a cleaning nozzle, a plurality of cleanings can be performed from a hot water tank. A solenoid valve for flow switching is provided in each hot water supply path that supplies hot water to the hot water nozzle, and the closing point of the solenoid valve is delayed from the point in time when the pressurized water supply means stops to remove residual pressure in the hot water tank. This system is equipped with a residual pressure removal means that prevents water hammer from being applied to the hot water tank and prevents large pressure from being constantly applied to the tank.This prevents damage to the stress concentration area of the hot water tank and prevents water leakage. This makes it difficult for hot water to occur, and the strength of the hot water tank can be lowered, so material costs can be reduced and costs can be reduced, and the hot water tank can be easily designed.
