Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention comprises a transmitter and a receiver for a remote control signal,
The present invention relates to a device for performing flush water supply to a toilet by remote control operation.

(Prior Art) There has been known a water supply device in which flush water supply is prohibited to save water until a predetermined time has elapsed after supplying flush water to a toilet. The prohibition of continuous (double) water supply is constituted by timer means for setting a prohibition time and means for invalidating the cleaning input during the prohibition time.

For this reason, in a device that includes a transmitter and a receiver for a remote control signal and controls water supply based on a remote control command from the transmitter, the transmitter / receiver can be operated even during the continuous (double) water supply prohibition time. In operation, the receiver has overridden the cleaning commands sent from the transmitter during the inhibit time.

(Problems to be Solved by the Invention) However, it is not desirable to keep the transmitter and the receiver operating even during the continuous (double) water supply prohibition time in order to reduce the power consumption of the device.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a flush water supply apparatus for a toilet, which can eliminate unnecessary power consumption during a continuous (double) water supply prohibition time and can eliminate means for invalidating a flush input.

(Means for Solving the Problems) Means taken by the present invention to solve the problems and achieve the object are as follows.

According to a first aspect of the present invention, there is provided the cleaning water supply apparatus, wherein the receiver is provided with a reception timer means, and the reception operation is stopped until a predetermined time has elapsed since the water supply apparatus was operated.

(Operation) In the flush water supply device of claim 1, when the supply of flush water to the toilet is started, the receiver stops the receiving operation for a predetermined time.

Therefore, the cleaning water is not supplied a plurality of times within the predetermined time.

(Example) Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

Key K2, which is a startup input means for small cleaning, and keys K1 and K2
Transmission control circuit 21 that generates a command signal (for example, a signal obtained by modulating a carrier clock with a command code) based on an input from
And a transmission circuit 22 for transmitting (light emitting) a remote control signal using infrared light from the infrared light emitting diode LED based on the command signal, and a battery 23.

And a determination processing means 32 for generating a solenoid valve drive output 32a based on the detected output 31a. The determination processing means 32 generates the solenoid valve drive output 32a for a long time (tL) for a large cleaning command, and generates the solenoid valve drive output 32a for a short time (tS) for a small cleaning command. It is configured as follows.

While the timer output is occurring, the switch means 33c is turned off, the power supply to the receiving circuit 31 is stopped, and the receiver 30 stops the receiving operation (FIG. 3f). When the key K2 for starting small cleaning is pressed (FIG. 3b), the output time tS (tS <
tL) The solenoid valve 40 is opened, and during this time, cleaning and water supply is performed.

Next, a modified example of the present invention will be described with reference to FIG.
The same parts as those in the embodiment shown in FIG. 1 are denoted by the same reference numerals, and the description is omitted.

The transmitter 60 of the cleaning water supply device 50 shown in FIG. 4 includes a non-contact type start-up input unit 61 and a transmission inhibition timer unit 62.

The non-contact type activation input means 61, 61 include a cycle control means 61a that repeatedly generates a pulse signal at a predetermined cycle, a light projecting unit 61b that emits infrared light of a predetermined wavelength based on the pulse signal, and a reflection unit. Light receiving unit 61c that detects the infrared rays

Consists of One end of the switch means 33c is connected to the plus side of the battery 23, and the other end is connected to the power supply 21b of the transmission control circuit.

The receiver 70 is obtained by removing the reception stop timer means 33 from the receiver 30 of FIG.

With the above configuration, after transmitting the command signal, the power supply to the transmission control circuit 21 is stopped during the transmission stop time tOFF, and the transmission of the remote control signal from the transmitter 60 is stopped.

As means for stopping the transmission of the remote control signal,
The power supply to the transmission circuit 22 may be stopped, or the transmission control circuit
When the 21 is configured by a one-chip microcomputer, the microcomputer may be set to the standby mode by the output of the timer means 62b to stop the transmission control function.

 Next, a modification of the present invention will be described with reference to FIG.

The cleaning / water supply device 80 shown in FIG. 5 has the same configuration as that of FIG. 4 except that the transmitter 90 is different from the transmitter 60 of FIG.

The transmitter 90 shown in FIG. 5 is a non-contact type activation input means.
The power supply to 61, 61 is performed via the switch means 33c in the input stop timer means 91, and the detection signals 61e, 61f of the activation input means 61, 61 are supplied to the timer means 91 via the OR circuit 91a.
It is configured to input to b. Therefore, a hand or the like is approached to the start input means 61, 61 to give a cleaning start input,
When this is detected, the time t defined by the timer means 91b
The power supply to the OFF start input means 61, 61 is cut off and the operation stops.

The detection of the activation input means 61, 61 may be stopped by, for example, stopping the operation of the cycle control circuit and stopping the light emission from the light emitting unit.

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

For simplicity of description, the solenoid valve 41 is an electromagnetic valve that opens while the voltage is being applied.However, from the viewpoint of reducing the power consumption of the device, the solenoid valve 41 includes a latching solenoid. Depending on the direction of the pulse current flowing through this solenoid, the valve is opened by a self-holding valve that operates from open to closed, or from closed to open, or by applying a pulse to the starting solenoid, and by applying a pulse to the recovery solenoid. The self-holding valve is driven by using a two-winding type self-holding valve that is in a closed state, generating a drive output corresponding to each of these valves in the determination processing circuit 32, or a valve drive interface circuit (not shown) or the like. Is desirable.

In addition, by stopping the operation of the receiver, the operation of the transmitter, and the detection of the activation input unit, the power consumption of both the receiver and the transmitter can be reduced.

Further, the number of keys or non-contact type activation input means is arbitrary. Remote control signals are not limited to those using infrared light,
An ultrasonic wave or a weak radio wave may be used.

(Effect of the Invention) As described above, the cleaning water supply device according to the present invention
Stop the operation of the remote control signal receiver until a predetermined time elapses after washing water supply once, and continue (double)
Since the reception input of the remote control signal for washing is stopped (prohibited), power consumption can be reduced by stopping the receiving operation, in addition to the water saving effect by preventing continuous (double) washing. In particular, when a battery or the like is used as a power source, it can greatly contribute to prolonging the life of the battery.

Further, since the reception of the remote control signal is stopped, a circuit or control means for invalidating the cleaning input during the continuous (double) cleaning prohibition time is not required, and the circuit scale or the size of the control program is reduced. Can contribute a little.
