SUMMARY OF THE INVENTION In view of the above points, the present invention has been devised in order to solve the above-mentioned problems in the prior art. A normally closed solenoid valve is disposed between the pipe and the first nozzle, and the solenoid valve is connected to the water inlet connected to the pipe, the water outlet connected to the first nozzle, and the water inlet connected to the first nozzle. A first flow path communicating the water port with the water outlet, a valve seat provided in the first flow path, and interlocking with a plunger, opening and closing the first flow path by coming into contact with and separating from the valve seat; A valve body, and having a second flow path that branches off the first flow path bifurcated on the upstream side of the valve seat and communicates with the second nozzle, and the second flow path A poppet for opening and closing a second flow path is provided, and the first flow path is bifurcated downstream of the valve seat and connected to the back side of the poppet. A third flow path is provided, wherein the poppet is elastically urged in a valve opening direction by a spring, and is closed by water pressure supplied to the back side from the third flow path. The present invention provides a human body washer that performs cleaning.

[0006]

The cleaning device of the present invention has only one solenoid valve.
The solenoid valve is a normally closed type, which opens when energized, and closes when energization is stopped. On the other hand, the poppet is a normally open type. When the solenoid valve is opened, the poppet is closed by receiving water pressure from the rear side, and when the solenoid valve is closed, the poppet is opened by elasticity of a spring. The cleaning device of the present invention operates as follows when the solenoid valve is energized and de-energized. That is, if the solenoid valve is not energized while water is supplied from the water supply means, the solenoid valve is closed and the poppet is opened, so that water is supplied from the water inlet to the second port. It reaches the second nozzle through the flow path and jets out from the second nozzle. The second nozzle is, for example, a buttocks washing nozzle. When the solenoid valve is energized, water reaches the first nozzle from the water inlet through the first flow path and is ejected from the first nozzle to open the solenoid valve. The first nozzle is, for example, a device cleaning nozzle. Part of the water that has passed through the valve seat of the first flow path is supplied from the third flow path to the back side of the poppet, closes the poppet against the elasticity of the spring, and closes the second flow path. close.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

As shown in FIGS. 1 and 2, a normally closed solenoid valve 23 is arranged between a pipe 21 connected to a water supply means (not shown) such as a pump and a nozzle 22 for cleaning the apparatus. The electromagnetic valve 23 has a water inlet 24 connected to the pipe 21 and a water outlet 2 connected to the apparatus cleaning nozzle 22.
5 and a first flow path 2 communicating the water inlet 24 and the water outlet 25.
6, the valve seat 27 provided in the first flow path 26, and the first flow path 26
And a valve element 29 that opens and closes. First channel 26
Is bifurcated on the upstream side (left side in the figure) of the valve seat 27,
A second flow path 31 communicating with the posterior washing nozzle 30 is provided, and the second flow path 31 is provided with a poppet 32 for opening and closing the flow path 31. The poppet 32 reciprocates vertically in the drawing. 33 is a pipe, 34 is a nozzle cylinder,
35 is a return spring, and 36 and 37 are ejection ports. The first flow path 26 is branched into two at the downstream side (upper and lower sides in the figure) of the valve seat 27, and the third flow path 38 communicates with the back side of the poppet 32.
The poppet 32 is elastically urged in the valve opening direction by a spring 39, and when water pressure is supplied to the rear side from the third flow path 38, the poppet 32 is closed against the elasticity of the spring 39 by this water pressure. I'm excused.

The above washer operates as follows. That is, when the washing start switch is pressed, the pump is driven to supply water from the water supply means to the water inlet 24 via the pipe 21, but the solenoid valve 23 remains de-energized, and the solenoid valve 23 Is closed and the first flow path 26 is closed, while the poppet 32 is open and the second flow path 31 is open. Channel 31
The water is supplied to a nozzle cylinder 34 via a pipe 33, and the posterior washing nozzle 30 is extended by being pushed by water pressure, and water is ejected from an ejection port 36 to wash the human body. Next, when the washing stop switch is pressed, the solenoid valve 23 is energized while water is supplied, and the solenoid valve 23 opens to open the first flow path 26, so that the water reaches the apparatus cleaning nozzle 22. From the outlet 37. Part of the water that has passed through the valve seat 27 of the first flow path 26
2, the poppet 32 is closed against the elasticity of the spring 39 to close the second flow path 31. Accordingly, no water pressure is applied to the posterior washing nozzle 30, and the posterior washing nozzle 30 is pushed back to the retracted position by the return spring 35, and the posterior washing nozzle 30 returned to the retracted position.
