<Example> Embodiments of the present invention will be described below based on the drawings.

In this embodiment, as shown in FIG. 1, the water washer (1) is a urinal (Ia), and above the urinal (1a)
To be more precise, a sensing part (
2) is installed in an embedded manner, and the stop circuit (8) is composed of a counter (8a) and a switch (8b), and the counter (8a) receives the light emitting signal output from the sensor circuit (3). The amount of consumption of the battery (7) is detected by increasing the power level by four times.

The sensing section (2) includes a light emitting element (2a) consisting of a light emitting diode.
) and a light receiving element (2b) consisting of a phototransistor.The light emitting element (2a) emits infrared light based on the light emitting signal output from the sensor circuit (3). This infrared light hits the user who is standing in front of the urinal (1a) to use the toilet and is diffusely reflected. When the light receiving element (2b) receives a part of this reflected light, the sensor circuit (3) Output the light reception signal to.

The sensor circuit (3) is a light projection drive that communicates with the light projection cable (2a) through a counter (8a) of a stop circuit (8), which will be described later, and outputs a light projection signal to the element (2a). (not shown) and a light-receiving amplifier (not shown) that communicates with the light-receiving element (2b) and inputs the light-receiving signal, and the light-emitting drive continuously transmits the light-emitting signal at a predetermined period. Send messages to others.

When the light-receiving amplifier emits infrared light from the light-emitting element (2a), if it inputs a light-receiving signal even once and detects the presence of a user, it outputs a sensing signal to the control circuit (4). If no light reception signal is input even though light is emitted, a clear signal is output to the control circuit (4).

Further, the sensor circuit (3) is turned ON-OFF based on the output from the counter (8a) of the stop circuit (8), which will be described later.
The operation switch (8b) is connected to the battery (7) of the drive power source, and the operation switch (8b) is turned on and electricity is supplied from the battery (7). It is possible to output a signal and input a light reception signal.

The control circuit (4) counts only the sensing signals from the sensor circuit (3), and when this count exceeds a set number, it outputs a drive signal to the drive circuit (5) for a predetermined period of time. From the sensor circuit (3) to
When the rear signal is input, the above count number is returned to O.

Further, the control section 28 (4) is in communication with the battery (7) and is always energized.

The drive circuit (5) inputs the drive signal output from the control circuit (4) and outputs a valve open signal or a valve close signal to the water supply section (6) to electrically control the operation of the water supply section (6). In this embodiment, when a drive signal is input, a valve opening signal is simultaneously output to energize the operating coil of the latching solenoid (6a) that constitutes the water supply section (6) for a predetermined period of time, for example, 20ml. At the same time, when the drive signal is no longer input, a valve closing signal is output and the return coil of the latching solenoid (6a) is energized for a predetermined period of time, for example, 20 m seconds.

Further, the drive circuit (5) is connected to the battery (7) via the stop circuit (8) and the switch (8b) in the same manner as the sensor circuit (3).
), and operates when the switch (8b) is in the ON state, and stops operating when the switch (8b) is in the O or FF state.

The water supply section (6) consists of a latching solenoid (6a) and a flush valve (6b) that opens and closes when the latching solenoid (6a) operates, and in the case of this embodiment, connects the water supply source and the urinal (1a). Connecting water supply channel〈9
), and a branch flow path (not shown) that connects the pressure seedlings defined in the flash valve (6b) and the secondary side of the flash valve. A latching solenoid (6a) is provided.

The latching solenoid (6a) energizes the operating coil and the return coil to move the Blanchille up and down to open the valve section 111, and after the valve section is operated, even if the energization to these coils is stopped, the valve state remains unchanged. In this embodiment, when the valve part is opened, water in the pressure chamber of the flush valve (6b) flows to the secondary side of the flush valve (6b) via the branch flow path. When the valve is opened at the same time as the discharge, the flush valve (6b
) is stopped from flowing out of the pressure chamber.

The flash valve (6b) has a conventionally well-known structure.
A pressure seedling is formed behind the main valve body which is movably arranged inside the pressure chamber, and when the water in the pressure chamber decreases, the main valve body gradually moves to the pressure maximum side and opens the valve, allowing cleaning from the water supply source. Water is supplied to the urinal (1a) through the water supply channel (9), and when the outflow of water in the pressure chamber is stopped, it gradually enters the pressure chamber through a small passage opened in the main valve body. As water begins to flow in, the main valve body moves little by little in the direction of closing the valve and finally closes, stopping the water supply to the urinal (1a).

On the other hand, the counter (8a) of the stop circuit (8) is arranged in the electrical path between the sensing section (2) and the sensor circuit (3), and counts the light emitting signal output from the sensor circuit (3). When this count reaches a set number, an OFF signal is output to the switch (8b).

The switch (8b) is arranged in the electrical path connecting the battery (7) with the sensor circuit (3) and the drive circuit (5),
Normally, they are kept in the ON state and energized, but only when the OFF signal from the counter (8a) is input, the sensor circuit (3) and the drive circuit (
5) Stop energizing.

In addition, the counter (8a) may be placed on the wall (
When the reset button (8C) is output by manual operation or the C cut signal is input, the count number is pushed back to O, and when the count number reaches the set number, the switch (8C) is placed.
If the above reset signal is input while the OFF signal is being output to b), the output of the OFF and F signals is stopped.

Therefore, the water supply control l (l device normally operates the water supply part (6) when the sensing part (2) detects the user,
From the sensor circuit (3) to the light emitting cord (2a) of the sensing section (2)
) Each time a light projection signal is output to the counter (8a), the count number of the counter (8a) increases by one, and when this count number reaches the set number, the amount of consumption of the battery (7) is detected and the switch (8b) is sent. Outputs an OFF signal and activates the sensor from the battery (7).
The power supply to the circuit (3) and the drive circuit (5) is stopped to stop their operation.

However, if the reset button (8c) is manually operated at this time, the counter (8a) reset signal is output, the count becomes O, the switch (8b) is turned on, and the battery (7 ) can be operated for a period of time until it is replaced.
