[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a washbasin equipped with a pop-up valve so that hot water or water discharged from a faucet can be stored therein.

[Conventional technology]

Wash basins equipped with faucets and pop-up valves have been widely used in the past. This pop-up valve is used to store water or hot water in the washbasin by opening and closing the drain port. Usually, a pop-up shaft protrudes from the back of the washbasin, and the shaft can be lifted or By pushing the pop-up valve, the pop-up valve is opened and closed.

[Problem that the invention attempts to solve]

If you close the pop-up valve and store hot water in a conventional washbasin, you may forget to drain it after use.
There was a risk that it would cause inconvenience to the next user or that dirt would stick to the washbasin.

[Means for solving problems]

The washbasin of this invention can discharge water by operating a switch.
It is equipped with a water discharge valve that shuts off water and a pop-up valve with a drive device that operates water storage/drainage,
Further, a control device is provided which outputs a valve opening signal to the pop-up valve driving device when a predetermined time has elapsed after the water is stopped by the water discharging valve switch.

[Effect]

In the present invention, when a predetermined period of time has elapsed after discharging water has stopped, if the pop-up valve is closed at that time, it is forcibly opened and water is drained.

〔Example〕

The present invention will be described in more detail below with reference to embodiments shown in the drawings.

FIG. 1 is a plan view of a washbasin according to an embodiment of the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof.

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. The valve 18 is equipped with a drive motor 18a for adjusting the flow rate and stopping water. Reference numeral 24 is a spout cap attached to the faucet 14.

A switch panel 26 is provided on the top surface of the faucet 14, and this switch panel 26 has a water discharge/water stop switch (water discharge valve switch) 28 and a lamp 30 for indicating that the switch 28 has been operated to discharge water. 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.

Reference numeral 42 is a drain pipe, and the solenoid 38
is attached to this drain pipe 42 via a mounting member 44. In addition, the iron core of the solenoid 38 is
It is connected to a valve stem (not shown) of a pop-up valve via a kick lever 46, and when the solenoid 38 is energized, the iron core protrudes and the pop-up valve closes. Conversely, when the solenoid 38 is demagnetized, the pop-up valve 32 opens due to the biasing force of a return spring (not shown).

In this faucet device, the water discharge/water stop switch 2
By operating the button 8, water discharge/stopping can be switched, and by operating the switch 34, the pop-up valve 32 can be opened and closed. Furthermore, after a predetermined period of time has passed after operating the switch 28 to stop the water, the solenoid 38
A valve opening signal 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;
It is a pop-up switch and is connected between the power supply circuit and ground via resistors R ₁ and R ₂ . Reference numerals 50 and 52 are NAND circuits, one input terminal of which is connected to a power supply circuit. Also, NAND
The other input terminal of the circuit 50 is connected to the non-grounded side of the water discharging/water cutoff switch 28 via resistors R ₃ and R ₄ , and the other input terminal of the NAND circuit 52 is similarly connected via resistors R ₅ and R ₆ . Pop-up switch 34
connected to the non-grounded side of the Note that the resistances R ₃ , R ₄ ,
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
6 is connected to its collector. Further, the collector of the transistor 62 is connected to the solenoid 38 . Further, in the flip-flop 56, its terminal and the D terminal are connected.

In order to perform an initial reset of these flip-flops 54 and 56, the power supply circuit is grounded through a diode D and a resistor _R7 that are connected in parallel with a capacitor _C3 , and the ground side of this capacitor _C3 is connected to a resistor _R8.
Reset R of the flip-flop 54 via
It is 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. It is configured to include an OR circuit 80 whose output side is connected to the reset terminal of the ripple counter 70. One input terminal of OR circuit 80 is connected to the terminal of flip-flop 56, 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 G indicate the timing shown in FIG.

First, when you turn on the power circuit, switch A and switch 2 are turned on.
The non-grounded sides of the flip-flops 54 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.

Incidentally, when the terminal of the flip-flop 56 goes into the H state, the ripple counter 70 goes into the 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, the reset state of the ripple counter 70 is released by the terminal of the flip-flop 56 going into the L state, and the ripple counter 70 starts counting by the input pulse from the oscillation circuit 68. When this count reaches the set count, the output terminal Qn becomes H.
The flip-flop 56 is reset, and the Q terminal of the flip-flop 56 becomes L and the terminal becomes H.
C. This turns off the transistors 60 and 62, turning off the lamp 36 and turning off the solenoid 3.
8, the pop-up valve 32 is opened and water is drained. Furthermore, since the terminal of the flip-flop 56 becomes H, the ripple counter 70
is immediately reset.

Thereafter, when the pop-up switch 34 is pressed again (D), the reset state of the ripple counter 70 is similarly released and counting is started. Therefore, before the ripple counter 70 counts the set number as in this case, the water discharging/water stop switch 28 is turned off.
When E is pressed, the NAND circuit 50 outputs a positive pulse to the flip-flop 54, and the flip-flop 5
The Q terminal of No. 4 goes into the H state, and the water spouting control circuit 82 operates to start spouting water, and at the same time, the transistor 58 turns on and the water spouting indicator lamp 30 lights up. Further, the H signal at the Q terminal of this flip-flop 54 is sent to the ripple counter 7 through an OR circuit 80.
0 is input to the reset terminal, and the ripple counter 70 enters the reset state. After this water discharging state continues for a while, when the water discharging/water stop switch 28 is pressed one more time, the F, NAND circuit 50 emits one pulse, and the Q terminal of the flip-flop 54 becomes the L state, and the water is stopped and the lamp 30 The lights go out. Also, the reset state of the ripple counter 70 is released and counting starts.

Therefore, when this ripple counter 70 counts a predetermined number (that is, when a predetermined time has elapsed),
The Qn output of the ripple counter 70 becomes H and G,
Flip-flop 56 is reset and its Q terminal goes to the L state. As a result, transistor 6
0 and 62 are turned off, the solenoid 38 is demagnetized, water is drained from the basin, and the lamp 36 is extinguished. In addition, the flip-flop 56
The ripple counter 70 is held in a reset state by transmitting the H output from the terminal.

In this way, according to this circuit, if the pop-up valve is closed after a predetermined period of time has elapsed since the water has been cut off, the pop-up valve is automatically opened and water is drained from the washbasin. Therefore, even if the pop-up valve is closed due to misoperation or mischief, the pop-up valve will automatically return to the open state after a predetermined period of time has elapsed.

[Effect of idea]

As described above, according to the present invention, the pop-up valve is automatically opened after a predetermined period of time has passed after the water has stopped, so even if you forget to drain the water from the basin, the water will be drained automatically. This prevents 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.
