Abstract

PURPOSE:To contrive to save water and electricity and, at the same time, to reduce circuits and controlling means by suspending transmitting and receiving operations for remote control signals or inputting means for a starting signal for a specified period of time after supply of cleaning water to a flush toilet stool, and by preventing thereby continual (or double) cleaning. CONSTITUTION:A transmitter 20 and a receiver 30 for signals for remote-control operations are installed in a toilet room A, and a water supply device 40 equipped with a solenoid valve 41 is connected to a cleaning-water supply pipe F so that the device can communicate with a toilet stool B. Timers 33, capable of suspending transmitting and receiving operations or inputting of starting signal for a specified period of time after actuation of the water supply device 40, are provided respectively to the transmitter 20 and the receiver 30. When a toilet user pushes a key K1 after supply of the cleaning water, the timer- output develops and the water-supply stops with the transmitting and receiving operations or inputting of starting signals suspended. Thereby continual (or double) cleaning can be prevented and while contriving to save water and electricity, circuits and controlling means can be reduced.

In each embodiment, the reception stop time, transmission stop time, and input stop time tOFF are arbitrary, but in order to prevent continuous (double) cleaning, a time of several tens of seconds to several minutes is desirable.

In order to simplify the explanation, the solenoid valve 41 is a solenoid valve in which the valve to which voltage is applied is in the open state, but from the viewpoint of reducing the power consumption of the device, a latching solenoid may be provided. It is a self-holding valve that operates from open to close or from close to open depending on the direction of the pulse current flowing through this solenoid, or it is a self-holding valve that operates by pulse energization to the starting solenoid, and by pulse energization to the recovery solenoid. It is possible to drive the self-holding valve by using a two-winding self-holding valve that is in a closed state, and generating drive output corresponding to these multiple valves in the judgment processing circuit 32 or a valve drive interface circuit (not shown). desirable.

Further, by stopping the operation of the receiver, stopping the operation of the transmitter, and stopping detection of the activation input means, it is possible to reduce the power consumption of both the receiver and the transmitter.

Further, the number of keys or non-contact activation input means is arbitrary. In addition to using infrared rays, the remote control signal may also use ultrasonic waves, weak radio waves, or the like.

Until a predetermined period of time has elapsed after water supply for cleaning, the operation of the remote control signal receiver or transmitter is stopped, or the detection operation of the non-contact type start input means is stopped,
Since it is configured to stop (prohibit) reception or transmission of remote control signals or start input for continuous (double) cleaning,
In addition to saving water by preventing continuous (double) washing, stopping each operation also reduces power consumption. In particular, when a battery or the like is used as a power source, it can greatly contribute to extending the life of the battery.

In addition, since the configuration is such that detection of startup input is stopped and remote control signal transmission or reception is stopped, there is no need for a circuit or control means to disable cleaning input during the continuous (double) cleaning prohibition time, and the circuit size is reduced. or control program size.
