Reference numeral 10 denotes a washbasin, which is attached to a cabinet 12, and has a faucet fitting 14 fixed to its upper surface. In the present invention, the faucet fitting 14 is connected to a water discharge valve 18 via a water supply pipe 16, and a water pipe 20 is connected to the water discharge valve 18.

It is provided. Also provided are a pop-up switch 34 for opening and closing the pop-up valve 32 of the washbasin 10 to store or drain water, and a lamp 36 that lights up when the pop-up valve 32 is closed. Reference numeral 38 indicates a solenoid as an opening/closing driving device for the pop-up valve. and,
Operation signals from these switches 28 and 34 are both input to a control device 40, and signals are output from the control device 40 to the motor 18a, the lamps 30 and 36, and the solenoid 38.

Further, after a predetermined period of time has elapsed after the switches 34 and 28 are operated to close the pop-up valve and stop water spouting, a valve opening signal for the solenoid 38 is output.

Next, the circuit configuration of a control device that performs such control will be explained with reference to FIG.

Reference numerals 28 and 34 are the aforementioned water discharge/water stop switches;

R ₅ and R ₆ are grounded via capacitors C ₁ and C ₂ , respectively.

The output terminals of NAND circuits 50 and 52 are connected to clock CL terminals of flip-flops 54 and 56, respectively. The flip-flop 54 is for controlling water discharge, and its Q output terminal is connected to the water discharge control circuit 82 and the base of the transistor 58. Note that the terminal of this flip-flop 54 is connected to its D terminal.

The transistor 58 is used to turn on the water discharge indicator lamp 30, and the lamp 30 is connected to its collector. Note that in this embodiment, both of the lamps 30 and 36 are LEDs.

The flip-flop 56 is used to open and close the pop-up valve 32, and as described above, the output terminal of the NAND circuit 52 is connected to its clock terminal. The Q output terminal is connected to the bases of transistors 60 and 62. The transistor 60 is used to indicate that the pop-up valve is closed (water is stored), and the lamp 3

In order to initialize these flip-flops 54 and 56, the power supply circuit connects the capacitor C ₃
The grounding side of this capacitor _C3 is grounded through a diode D and a resistor _R7 which are connected in parallel with the
It is connected to the reset R terminal of the flip-flop 54 via _R8 , and further connected to the reset terminal of the flip-flop 56 via an OR circuit 64.

Reference numeral 66 is a circuit that outputs a signal to demagnetize the solenoid 38 when a predetermined time has elapsed after water discharging is stopped. The circuit includes an OR circuit 80 whose output side is connected to the reset terminal of the ripple counter 70, a flip-flop 84, and an AND circuit 86. One input terminal of OR circuit 80 is connected to a terminal of flip-flop 84, and the other input terminal is connected to the Q terminal of flip-flop 54.

Next, the operation of the circuit configured as described above will be explained with reference to the time chart shown in FIG.
Note that .about. in FIG. 5 respectively indicate the voltage levels at .about. in FIG. 4. In addition, the following
A to F indicate the timing shown in FIG.

First, when you turn on the power circuit, switch A and switch 2
The non-grounded sides of the flip-flops 8 and 34 go into the H state, and one pulse is generated by the action of the capacitor _C3, etc., and this one pulse is sent to the flip-flops 54,
56 reset terminals to reset them and set each Q terminal to the L state.

By the way, when the terminal of flip-flop 56 becomes H state, flip-flop 84 is reset and its terminal becomes H state, and ripple counter 70 becomes reset state.

In this state, if you press the switch 34 once, B.
Since one input side of the NAND circuit 52 is in the L state for a short time, the NAND circuit 52 generates one positive pulse, which is input to the clock terminal of the flip-flop 56, so that the Q terminal of the flip-flop 56 becomes H. As a result, the transistors 60 and 62 are turned on, and the water storage indicator lamp 36 is turned on and the solenoid 38 is energized. Then, the pop-up valve closes by energizing the solenoid 38, allowing water to be stored.

Furthermore, when the terminal of the flip-flop 56 goes into the L state, the reset state of the flip-flop 84 is released, but since the CL terminal of the flip-flop 84 is grounded, the output level up to that point is maintained at H. Thereafter, when the water discharge/water stop switch 28 is pressed once, the C and NAND circuit 50 generates an H pulse, and the Q terminal of the flip-flop 54 becomes H. As a result, the water spouting control circuit 82 is activated to start water spouting, and the transistor 5
8 is turned on, and the lamp 30 is lit. Furthermore, since both input levels of the AND circuit 86 become H, the output of the AND circuit 86 becomes H, and the flip-flop 84 is preset. As a result, the terminal of flip-flop 84 becomes L. However, in the OR circuit 80, since the signal from the flip-flop 54 becomes H,
The output to the ripple counter 70 continues to be in the H state.

Thereafter, when the water discharging/water cutoff switch 28 is further pressed, the D and NAND circuit 50 generates an H pulse, the Q terminal of the flip-flop returns to L, and water discharging is stopped and the lamp 30 is turned off. Also, AND circuit 8
6 becomes L, and the flip-flop 84 is released from the preset state, but since the CL terminal is grounded, the terminal output continues to be in the L state. On the other hand, in the OR circuit 80, since both inputs become L, its output becomes L and E, and the reset state of the ripple counter 70 is released, and the ripple counter 70 starts counting by the input pulse from the oscillation circuit 68. Start. When this count reaches the set count number, the output terminal Qn becomes H, the flip-flop 56 is reset, and the terminal of the flip-flop 56 becomes L and the Q terminal becomes H. As a result, the transistors 60 and 62 are turned off, and the lamp 36 is extinguished and the solenoid 38 is demagnetized to open the pop-up valve 32 and drain water. Further, when the terminal of the flip-flop 56 becomes H, the flip-flop 84 is reset, and its Q output becomes H, so that the ripple counter 70 immediately enters the reset state.

As described above, according to this circuit, when the pop-up valve is closed and water is stopped for a predetermined period of time, the pop-up valve is automatically opened and water is drained from the washbasin.

[Effect of idea]

As described above, according to the present invention, the pop-up valve is closed and the pop-up valve is automatically opened when a predetermined period of time has elapsed after the water has stopped. Drainage can be done in a timely manner, thereby preventing inconvenience to the next user or dirt from adhering to the inner surface of the washbasin.

In addition, selection of water storage and drainage in the washbasin can be made by simply operating an electric switch, which is extremely simple and does not require much force and can be easily operated by even the elderly or children. Further, the conventional manually operated pop-up shaft is not required, and the fear of water leakage from the insertion hole of the pop-up shaft is also eliminated.
