A light receiver 2b of a transmission type photo sensor 2 that receives external radiation is provided. Light emitter 2 The light-emitting surface and light-receiving surface of a and the light receiver 2b are along the front and rear surfaces of the toilet bowl body 1. It is arranged so that it is possible to detect anything obstructing the vicinity of the center of the opening 9. flight When this infrared ray is blocked by the dirt discharged into the container, the receiver 2b detects this. and sends a signal to the control unit 4. The light receiver 2b and the light emitter 2a are connected to a wire harness. It is connected to the control unit 4 by the lens and detected by the transmission type photo sensor 2. All signals are sent to the control section 4. The control unit 4 drives a valve installed in the toilet room. The valve drive unit 5 is connected to the opening/closing valve 7a and the flow rate adjustment valve 7. It is designed to instruct the opening and closing of b. The on-off valve 7a is arranged inside the toilet room. It can also be opened manually by opening the cleaning lever (not shown). It is something.

0012 In this way, the toilet is performed, and the infrared light emitted from the light emitter 2a of the transmission type photo sensor 2 When at least a part of the line is interrupted, the light receiver 2b detects this and sends a message to the control unit 4. send the number. In response to this, the control unit 4 instructs the valve drive unit 5 to open the on-off valve 7a. The toilet bowl will be flushed.
