It communicates via 62.

FIG. 6 shows a water circuit of the sanitary washing device. In the water channel from the branch tap 53 to the sanitary washing device main body 51, a check valve 60,
In the sanitary washing device main body 51 having a water stopcock 61, a strainer 62, and a connecting pipe 54, in order from the primary side, an actual flow valve 63, a water stop solenoid valve.
There are 64. The secondary side of the water stop solenoid valve 64 branches into a nozzle channel and a drain channel that communicate with the anal cleaning nozzle 65A and bidet cleaning nozzle 65B for cleaning a human body part. Waste water is water that is normally discharged into toilets and is not used for local cleaning in order to meet the minimum amount of water discharge specified by the Japan Water Works Association.

In the nozzle water channel, in order from the primary side, a flow control valve 66, a flow sensor 67, a water temperature tank 68, a nozzle switching solenoid valve 69A, 69
There is B.

The drainage channel has a sub-constant flow valve 70 and a vacuum break valve 71 in order from the primary side.

Further, a relief valve 72 for bypassing a part of the washing water to the drainage channel when a water pressure equal to or higher than the set pressure is applied to the hot water tank 68 has a secondary side of the flow control valve 66 and a sub constant flow valve.
It is located on the 70 secondary side.

The operation of the sanitary washing device main body 51 when the user operates the washing switch is as follows.

First, the nozzle switching solenoid valve 69 according to the switch operation
One of A and 69B opens. Next, the water stop electromagnetic valve 64 is opened, and the flow control valve 66 is opened according to the output signal of the flow sensor 67 to obtain a predetermined washing flow rate. When the stop switch is operated,
The water stop solenoid valve 64 is closed, the nozzle switching solenoid valves 69A and 69B are closed, and the flow control valve 66 is closed in this order.

(Problems to be Solved by the Invention) However, in the case of such a configuration, when the water supply pressure at the installation location is high, the connection between the outlet 59 of the branch faucet 53 and the connecting pipe 54,
Water may leak from the connection between the connecting pipe 54 and the connection fitting 51A, causing damage to the house due to flooding and electric leakage of the device body 51.

The reason for this is that, after the sanitary washing device is installed, the stopcock 61 of the normal branch tap 53 is set to the fully open position. Therefore, the final water stop section of the sanitary washing device is the water stop electromagnetic valve 64 provided in the sanitary washing device main body 51. Therefore, the water supply pressure is always applied to the primary side of the water stop electromagnetic valve 64.

When the washing of the sanitary washing device main body 51 is stopped, the operation is a water stop solenoid valve.
Since the order of closing the valve 64, closing the nozzle switching solenoid valves 69A and 69B, and closing the flow rate control valve 66 is the order, the water hammer at the time of stopping the flow of water acts on the primary side of the shutoff solenoid valve 64. Similarly, when the ball tap 56A is closed after the low tank 56 is drained, the water hammer at the time of stopping the flow of water acts on the primary side of the water stop solenoid valve 64. The static load due to the water supply pressure and the dynamic load due to water hammer, the vibration is structurally weak, the connection between the outlet 59 of the branch faucet 53 and the connection pipe 54, the result of acting on the connection between the connection pipe 54 and the connection fitting 51A,
This loosens the connection, destroys the structure, and causes water leakage.

In particular, if water leaks during long periods of going out or sleeping at night, the discovery may be delayed, leading to flooding of the house and leakage of the sanitary washing device.

Therefore, the present invention, on the secondary side of the outlet 59 of the branch faucet 53, when the sanitary washing device main body 51 is not used, so that the feed water pressure is not applied, and washing is stopped, or the ball tap 56A is closed. Water hammer at the time of installation, even in an installation location with high water supply pressure, the outlet 59 of the branch tap 53
It is intended to provide a sanitary washing device capable of preventing water leakage from the connection part of the connection pipe 54 and the connection part of the connection pipe 54 and the connection fitting 51A.

(Means for Solving the Problems) In order to solve the above problems, the technical means of the present invention includes:
A branch faucet, a sanitary washing device body for washing a human body part,
Equipped with a connecting pipe connecting the branch faucet and the sanitary washing device main body,
The branch faucet has one inlet and two outlets, one of which is always in communication with the inlet, and the other of which is in communication with the inlet through a water shutoff solenoid valve. It is configured to be connected to a pipe.

(Operation) The operation of this technical means is as follows.

In other words, the final water stop section of the sanitary washing device (water stop solenoid valve)
The water supply pressure is applied to the connecting pipe and the sanitary washing device main body from the secondary side of the branch faucet to the connecting pipe and the sanitary washing device main body only during the cleaning operation, and the water stop solenoid valve is closed when not in use. As a result, water does not leak from the branch faucet and the connecting portion of the connecting pipe and from the connecting portion of the connecting pipe and the main body. In addition, the water hammer when the cleaning operation is stopped and when the ball tap is closed from the released state, the branch water tap and the connection pipe connection part on the secondary side of the water stop solenoid valve which is the final water stop part, the connection pipe and the connection pipe and the main body connection Since it does not reach the connection portion, it is possible to prevent the connection portion from loosening due to repeated load and vibration, and to prevent fatigue failure.
