Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for closing water supply of a sanitary washing device having nozzles which can be set at two positions, namely, anal washing and female local washing.

2. Description of the Related Art In the conventional sanitary washing device, a solenoid valve is used to prevent water from flowing through the nozzle when not washing. In the case of a nozzle having a dedicated nozzle for cleaning the anus and a nozzle for cleaning the female part, two solenoid valves were required for switching the nozzles, one for each.

Problems to be Solved by the Invention Unlike the conventional method, in which a dedicated nozzle for anus washing and local washing of a woman are provided and these are switched by a solenoid valve, the nozzle is provided at two positions of the anus washing and the female local washing. In order to realize cost reduction and high functionality, a method of driving a water stop mechanism using this actuator while driving the

Means for Solving the Problems In order to solve the above problems, the present invention provides a washing nozzle driven by an actuator at two positions for anus washing and local washing of a woman, and a closing valve operated by the actuator. It is provided to prevent water from flowing through the nozzle when not cleaning. Since the nozzle has a function of being driven to a predetermined position by an actuator, it is possible to further swing the nozzle to enhance the cleaning effect, or to add a function such as fine adjustment of the nozzle position.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. In the figure, 1 is a toilet bowl, 2 is a flush water tank connected to the rear of the toilet bowl, 3 is a flush toilet seat unit connected to the toilet bowl 1, a hot water heating unit, a pressurizing unit, a washing unit and controls for controlling them. The seat is built in, and the toilet seat 4 and the toilet lid 5 are pivotally attached. The jet flow jetting portion 6 for jetting the washing water to the portion to be washed of the user seated on the toilet seat 4 is located at the tip of the expanding / contracting portion 7a of the nozzle 7 and is configured to project / withdraw from the washing toilet seat unit 3. The flush water tank 2 and the flush toilet seat unit 3 are connected by a water supply pipe 8 and communicate with a pump 8a in the flush toilet seat unit 3. Pump 8a
The water pressurized in 1 reaches the hot water supply unit 10 through the discharge channel 9. The hot water supply unit 10 includes a water inlet pipe 11, a hot water tank 13 having a hot water outlet pipe 12, a sheathed heater 14 built in the hot water tank 13,
The temperature sensor 15 detects the hot water temperature of the hot water tank 13, and the controller 16 controls the input to the sheath heater 14 so that the hot water temperature becomes appropriate. The hot water heated by the hot water supply unit 10 reaches the water shutoff valve 17 from the hot water outlet pipe 12. Stop valve 17
Has a closing function against the pressure difference due to the height difference between the wash water tank 2 and the wash toilet seat unit 3. Water stop valve 17 is nozzle 7
Is integrally provided at the rear of the and is biased by the spring 17a,
Diaphragm 1 set to separate from valve seat 17b during cleaning
The drive shaft 17e installed on the return side of the valve body 17d of 7c, the casing 17f supporting these, and the stopper of the drive shaft 17e.
17 g and the connection port 18 of the nozzle 7. The nozzle 7 is provided with an expanding / contracting portion 7a which is retracted by water pressure and a swinging means 20 driven by a motor 19. The swinging means 20 detects the swinging movement of the nozzle 7 in the front-back direction by the link mechanism 21, the swinging movement in the left-right direction by the guide means 22 for restricting the movement of the nozzle 7 around the axis, and the position of the nozzle 7 in the front-back direction. The position detecting means 23 is provided. The link mechanism 21 is the nozzle 7
A pair of fixing rings 24a, 24b integrally provided with the rotating ring 25 for rotatably supporting the pair of fixing rings 7 and a pair of shafts 26a, 26b provided on the rotating ring 25 by a motor 19. A pair of bearings 28a provided on the driven arm 27,
The drive part of the link mechanism 21 that is rotatably inserted into 28b and the nozzle guide 29 that holds the nozzle 7 slidably in the axial direction in order to support the movement of the nozzle 7 on the substrate 30. It is fixed rotatably in the movement direction of 7. Further, the guide means 22 for restricting the movement of the nozzle 7 around the axis is a guide pin 31 fixed to the nozzle guide 29, and the guide pin 31.
And a pin guide 33 having a groove cam 32 guided by 31. The groove cam 32 is constituted by a wave-shaped groove so as to move a predetermined distance to the left and right with respect to the reciprocating movement direction of the nozzle 7. The guide pin 31 has a shape that expands to the left and right toward the center of the nozzle 7 so that the guide pin 31 can smoothly move in the groove cam 32. The position detecting means 23 comprises a magnet 35 held by a magnet holder 34 provided coaxially with the arm 27, and a plurality of magnetic sensors 37 installed on a detection plate 36 installed in the vicinity of the magnet 35. Also, a plurality of magnetic sensors 37 are arranged.
Is fixed on the detection plate 36 so that the cleaning position of the nozzle 7 is the rotational position of the magnet 35 corresponding to at least two positions of the anal cleaning and the female local cleaning. In this embodiment, the magnetic sensors 37 are installed at four places, and are fixed on the detection plate 36 so as to correspond to the upper and lower limit positions of the nozzle 7 when swinging and cleaning the anus or the female part, respectively. There is.

Next, the operation during cleaning will be described. When the user turns on the washing switch (not shown), the nozzle 7 is at the initial position determined by the magnetic sensor 37 (the stop position of the nozzle 7).
After moving to a predetermined position, the position detection circuit 38 sets a predetermined amplitude, and the motor drive circuit 39 makes an oscillating motion. At this time, in the initial position of the nozzle 7, the water stop valve 17 presses the valve body 17a and the valve seat 17b by the drive shaft 17e which is in contact with the stopper 17g. 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 urging force of the spring 17a, and the hot water discharge pipe 12 communicates with the nozzle 7, and at the same time the pump 8a operates. The hot water in the hot water tank 13 is rotated and pressure-fed to the nozzle 7, and after pushing the expanding / contracting portion 7a of the nozzle 7 to a predetermined position, the hot water jet portion 6 jets the hot water to the portion to be washed by the user. Magnetic sensors provided at four positions on the detection plate 36 correspond to the upper and lower positions of the position of the nozzle 7 when the anus cleaning and the female local cleaning are performed. The set position and swing range of the nozzle 7 are defined by 37, and swing cleaning is performed at each position. At the end of cleaning, first, the rotation of the pump 8a is stopped, the cleaning water is stopped, and the water pressure disappears, so that the expandable part 7a of the nozzle 7 contracts and returns to its original position, and the entire nozzle 7 is initialized by the nozzle driving means 7. Return to the position (stop position of the nozzle 7). At this time, the water shutoff valve 17 exerts a water shutoff function by the valve body 17a being pressed against the valve seat 17b by the drive shaft 17e and brought into pressure contact.

According to the above configuration, the nozzle is not switched by the solenoid valve as in the conventional case, but is switched by the rocking means 20 of the nozzle 7, so that the cleaning effect by the nozzle 7 is enhanced and the water blocking function is rocked. Since the water shutoff valve uses the movement of the means 20, it is possible to significantly enhance the cleaning function without increasing the cost.

As described above, according to the sanitary washing device of the present invention, instead of switching the type of washing by the solenoid valve as in the conventional case,
Since the cleaning nozzle is moved by the actuator to switch the type of cleaning, and the actuator is used to move the water stop mechanism, cost reduction and high functionality can be realized.
