Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a water supply closing method for a sanitary cleaning device having a nozzle that can be set in two positions: anal cleaning and female private parts cleaning.

BACKGROUND OF THE INVENTION Conventional sanitary cleaning devices have used electromagnetic valves to prevent water from flowing through the nozzles when not cleaning. A device that has dedicated nozzles for cleaning the anus and for cleaning women's private parts requires a total of two solenoid valves, one for turning off the nozzle, and one for opening the nozzle.

Problems to be Solved by the Invention Instead of the conventional method of providing dedicated nozzles for anal cleaning and female private parts cleaning and switching these using a solenoid valve, a nozzle is installed in two positions for anal cleaning and female private parts cleaning. The objective is to drive the system with an actuator and use this actuator to eliminate the need for water supply mechanisms, thereby achieving lower costs and higher functionality.

Means for Solving the Problems In order to solve the above problems, the present invention provides a cleaning nozzle driven by an actuator in two positions for anal cleaning and female private parts cleaning, and a closure actuated by this actuator. A valve is installed to prevent water from flowing to the nozzle when not cleaning. Since the nozzle has a function of driving the nozzle to a predetermined position using an actuator, it is possible to further improve the cleaning effect by oscillating the nozzle, or to add functions such as fine adjustment of the nozzle position.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 7. In the figure, 1 is a toilet bowl, 2 is a flushing water tank connected to the rear of the toilet bowl, and 3 is a flushing toilet seat unit connected to the toilet bowl 1, including a hot water heating section, a pressurizing section, a cleaning section, and controls for controlling these. The toilet seat 4 and the toilet lid 5 are rotatably connected to each other. A jet jet spouting part 6 that spouts cleansing water to the area to be cleaned of a user seated on the toilet seat 4 is configured to appear and retract from the tip of the extensible part 7a of the nozzle 7 and from the cleaning toilet seat unit 3. The cleansing water tank 2 and the cleansing toilet seat unit 3 are connected by a water supply pipe 8, and further communicated with a pump 8a inside the cleansing toilet seat unit 3. pump 8
The water pressurized in step a reaches the hot water supply section 10 via the discharge flow path 9. Hot water supply section 10i/i, water inlet pipe 11, hot water outlet pipe 12
A heated water tank 13 having
The input to the heater 14 is controlled so that the hot water is at an appropriate temperature. The hot water heated by the hot water supply section 10 is supplied to the hot water outlet pipe 12.
This leads to the water stop valve 17. The water stop valve 17 has a closing function against a pressure difference caused by a height difference between the flush water tank 2 and the flush toilet seat unit 3.

The water stop valve 17 is integrally provided behind the nozzle 7, is biased by a spring 17a, and has a drive shaft installed on the return side of the valve body 17d of the diaphragm 17c, which is set to be separated from the valve seat 17b during cleaning. 17e, a casing 17f that supports them, a stopper 17g of the drive shaft 17e, and a connection port 18 of the nozzle 7. The nozzle 7 is equipped with an extensible part 7a that moves in and out by water pressure, and a swinging means 20 that is driven by a motor 19. The swinging means 2o detects the back and forth swinging of the nozzle 70 by the link mechanism 21, the left and right swinging by the guide means 22 that regulates the movement of the axis of the nozzle 7, and the longitudinal position of the nozzle 7. The position detecting means 23 includes a position detecting means 23. Link mechanism 21
are a pair of fixing rings 24a provided integrally with the nozzle 7.
, 24b.

A rotating ring 25 that rotatably supports the pair of fixed rings 7 and a pair of shafts 26 provided on the rotating ring 25.
a, 26b are the arms 27 driven by the motor 19;
A pair of bearings 28a provided in the.

Link mechanism 21 configured by being rotatably inserted into 28b
and the nozzle 7 to support the movement of the nozzle 7.
A nozzle guide 29 which is slidably held in the axial direction is fixed on a substrate 30 so as to be rotatable in the movement direction of the nozzle 7. Further, the guide means 22 for regulating the movement of the axis of the nozzle 7 is composed of a guide bin 31 fixed to the nozzle guide 29 and a pin guide 33 having a grooved cam 32 guided by the guide bin 31. The grooved cam 32 is formed into a wavy groove so as to move a predetermined distance left and right with respect to the reciprocating direction of the nozzle 7. 31 has a shape that allows smooth movement within the grooved cam 32. Position detection means 2
3 is arm 27.

Magnet 3 held by coaxial magnet holder 34
5 and a plurality of magnetic sensors 37 installed on a detection plate a6 installed close to the magnet 35.

Next, the operation during cleaning will be described. When the user turns on the cleaning switch (not shown), the nozzle 7 moves to the initial position determined by the magnetic sensor 37 (stop position of the nozzle 7).
y to a predetermined position, and the position detection circuit 38 detects υ.
A predetermined amplitude is set, and a swinging motion is performed by the motor drive circuit 39.

At this time, the water stop valve 17 is in the initial position of the nozzle 7.
Since the valve body 17a and the valve seat 17b are pressed against the drive shaft 17e that is in contact with the stopper 17g, the flow of hot water from the tap pipe 12 to the nozzle 7 is blocked. When the nozzle 7 moves to a predetermined cleaning position, the drive shaft 17e separates from the stopper 17g, the valve body 17d separates from the valve seat 17b by the biasing force of the spring 17a, and at the same time the hot water tap 12 communicates with the nozzle 7. The pump 8a rotates, and the hot water in the hot water tank 13 is force-fed to the nozzle 7, and the extension part 7 of the nozzle 7
After pushing out a to a predetermined position, it is ejected by the jet ejection part 6 onto the user's part to be cleaned. Swinging means 2 of nozzle 7
The setting position by 0 is 2 for anal cleaning and female private cleaning.
According to the above configuration, the nozzle is switched by the swinging means 20 of the nozzle 7, instead of switching the nozzle by a solenoid valve as in the conventional case. Since the structure is such that the cleaning effect of the nozzle 7 is enhanced, and the water stop function is a water stop valve that utilizes the movement of the swinging means 20, it is possible to significantly improve the cleaning function without increasing costs. became.

Effects of the Invention As described above, according to the sanitary cleaning device of the present invention, instead of switching the type of cleaning using a solenoid valve as in the past, the type of cleaning is changed by moving the cleaning nozzle with an actuator. By using this method to operate the water stop mechanism, lower costs and higher functionality can be achieved.
