A flash valve 4 is attached to the Western style toilet 1.
By operating 3 (FIG. 1), toilet flush water is supplied.

A main pipe for hot water supply and a main pipe for water supply are provided on the back side of the wall surface of the toilet room, and a hot water stopcock 10 and a water tap connected to these main pipes are provided on the wall surface of the toilet room. Water stopcock 11 is provided.
A hot water supply pipe 12 and a water supply pipe 13 are routed between the case 1 and the case 4.

As shown in FIG. 1, flow regulating valves (flow regulating valves) 14 and 15 having a water stopping function are provided in the middle of each of the pipes 12 and 13. Each of the pipes 12 and 13 is connected to a mixing valve 16 driven by a motor 16m so that hot water and water are mixed at an appropriate ratio and can be supplied to a cleaning nozzle 18 via a pipe 17.

From the hot water supply pipe 12, the waste water pipe 1
9 is branched, and low-temperature hot water is discarded to the toilet bowl 2. The pipe 19 is provided with a waste water valve 20 which is an open / close type electromagnetic valve.

The valves 14, 15, 16 and 20 are controlled by a control circuit 24 using a battery 21 as a power source.
A power switch 22 is provided on a power supply wiring between the battery 21 and the control circuit 24. The power switch 22 can open and close the contacts manually, and the contacts are opened (OFF) by the relay 23.

The control circuit 24 includes a cleaning switch 25 provided on the upper surface of the case 4 and a cleaning intensity adjustment switch 2.
6, 27, water temperature control switches 28, 29 and the toilet seat 5
Each signal of the seat sensor 30 for detecting that the user is seated is input. Further, to the control circuit 24, a signal from a temperature sensor 31 provided slightly upstream of a location where the waste water pipe 19 branches out of the hot water supply pipe 12 is also input. Note that a warning lamp 32 is connected to the control circuit 24.

A flush valve 43 driven by both a manual lever handle 41 and a solenoid 42 and a hydraulic power generator 44 are provided in a pipe 40 for supplying toilet flush water to the Western-style toilet 1. Yes,
A drive current can be supplied from the control circuit 24 to the solenoid 42 of the flash valve 43. When the flush valve 43 is opened and water flows through the pipe 40, the generator 44 generates electric power, and the electric power charges the battery 21 via the rectifier circuit 45 and the charging circuit 46.

Next, the contents of control by the control circuit 24 will be described. In this sanitary washing device, power is not supplied to the control circuit 24 unless the power switch 22 is turned on, and the sanitary washing device does not operate. This can save considerable power.

When the power switch 22 is turned on,
Power is supplied from the battery 21 to the control circuit 24. Then, first, the temperature detected by the temperature sensor 31 becomes a predetermined temperature (for example, 40 ° C.).
It is checked whether the temperature is above or not. When the temperature is lower than the predetermined temperature, the flow regulating valve 14 and the waste water valve 20 are opened, and the low-temperature water is discharged to the toilet bowl 2. The flow regulating valve 14 and the waste water valve 20 close when the temperature detected by the temperature sensor 31 reaches a predetermined temperature. If the temperature detected by the temperature sensor 31 does not reach the predetermined temperature within a predetermined time (for example, one minute) after the waste water valve 20 is opened, it is determined that something abnormal has occurred in the hot water supply boiler or the like and discarded. The water valve 20 is closed and the warning lamp 32 blinks.

When the power switch 22 is turned on, a timer built in the control circuit 24 is started. If the seating sensor 30 does not detect seating even after a predetermined time (for example, two minutes) has elapsed since the timer started, it is assumed that the user has left the toilet room without using the toilet and the relay 23 And the power switch 22 is forcibly opened (OFF). As a result, it is prevented that power is continuously supplied to the control circuit 24 needlessly.

A user sits on the toilet seat 5 and the washing switch 2
When 5 is operated, the flow regulating valves 14 and 15 are opened to a normal opening degree. In this case, since the hot water has already been drained, a suitable temperature of hot water is immediately jetted from the cleaning nozzle 18. On this occasion,
Operating the cleaning intensity adjustment switch 26 increases the cleaning intensity, and operating the cleaning intensity adjustment switch 27 decreases the cleaning intensity. When the water temperature control switch 28 is operated, the spouted water temperature increases, and when the water temperature control switch 29 is operated, the spouted water temperature decreases.

When the cleaning switch 25 is operated again, the ejection of water from the nozzle 18 stops.

Thereafter, when the user stands up from the toilet seat 5, the relay 23 is energized and the power switch 22 is forcibly turned on.
It becomes FF.

When the timer is started by turning on the power switch 22 and the power switch 22 is not turned off after the required time elapses after the seating sensor 30 detects the seating, for example, Toilet seat 5
In the case of an optical sensor, it is assumed that a heavy object is placed on the sensor or an object is covered on the front surface of the sensor, and power is supplied to the relay 23 to forcibly turn off the power switch 22.
