A water discharging device according to a second aspect of the present invention is the water discharging device according to the first aspect, wherein the valve and the human body detecting device are integrally and detachably attached to a tip of the water discharging pipe. is there.

[0007]

According to the water discharging apparatus of the first aspect, water can be discharged / stopped by operating a wireless switch with a foot or the like. In addition, two types of water discharge / water stop control of automatic water discharge and wireless switch operation can be performed. Moreover, the mechanism for receiving the optical signal from the wireless switch is shared with the optical signal receiving mechanism of the automatic water discharging device, and the mechanism is simple.

[0008] In the water discharge device according to the second aspect, the water discharge device according to the first aspect can be obtained by attaching the device to an existing water discharge pipe later.

Embodiments will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a sink having a water discharge device according to an embodiment of the present invention, FIG. 2 is a cross-sectional view of a main portion of the water discharge device, and FIG. 3 is a block diagram showing a control system of the water discharge device.

In FIG. 1, a basin 12 is provided in a cabinet 10, and a faucet fitting 16 provided with a water discharge pipe 14 so as to discharge water toward the basin 12 is provided.
2 attached to the back side. 18 is the faucet fitting 1
6 is a handle for water discharge provided in 6.

A water discharge device main body 20 is attached to a distal end of the water discharge pipe 14. As shown in FIG. 2, the attachment 22 is fixed to the distal end of the water discharge pipe 14 with a screw 24, and the casing 28 of the water discharge device main body 20 is fixed to the distal end of the water discharge pipe 14 via a cap nut 26. This casing 2
An electromagnetic valve composed of a valve 30 and a solenoid 32 is provided in 8, and water in the water discharge pipe 14 can pass through the valve 30 and flow out of an outlet 34 at the tip thereof.

A light emitting element 36 is provided on the bottom of the casing 28.
A sensor unit 40 having a light receiving element 38 is attached, and the sensor unit 40 and the circuit unit 42 are connected by a lead wire 44. The circuit unit 42 supplies a control signal to the solenoid 32 via a lead wire 46.

As shown in FIG. 3, a control device main body 48 and a valve driving device 50 are installed in the circuit unit 42, and the control device main body 48 is controlled based on a signal from the light receiving element 38.
Outputs a signal indicating that water should be discharged to the valve driving device 50,
When this signal is input to the valve driving device 50, the valve driving device 5
0 activates the solenoid 30 to open the valve 30.
Similarly, when a signal to stop water is given from the control device main body 48 to the valve driving device 50, the valve driving device 50 operates the solenoid 32 to close the valve 30.

A wireless foot switch 52 is provided in front of the cabinet 10 so as to supply an optical signal to the light receiving element 38.

[0015] In the water discharge device thus configured,
The handle 18 is opened so that the water supply pressure is applied to the water discharge pipe 14. In this state, if a hand is inserted below the water discharge device main body 20, the light receiving element 38 detects the inserted hand and a hand detection signal is input to the control device main body 48. Thereby, the valve drive device 50 operates the solenoid 32,
The valve 30 opens and water flows out of the outlet 34. Similarly, by operating the wireless foot switch 52 with a foot to give an optical signal to the light receiving element 38, the valve 30
Is opened and water is discharged.

When the hand is retracted from below the water discharge device main body 20, the hand detection signal of the light receiving element 38 is stopped, whereby the valve 30 is closed and the water is stopped. Similarly, when the foot is released from the wireless foot switch 52, light is no longer supplied to the light receiving element 38, the valve 30 is closed, and the water is stopped.

In the above embodiment, when the wireless foot switch 52 is depressed, an optical signal is continuously output from the switch 52, and when the foot is released from the foot switch 52, the optical signal is stopped. However, for example, the light may be continuously emitted when the wireless foot switch 52 is pressed once, and the light may be stopped when the foot switch 52 is pressed again.

According to the water discharge device of the present invention, the operation of the foot switch 52 can switch between water discharge and water stop. Further, in the present embodiment, the mechanism for receiving the optical signal from the wireless foot switch 52 and the optical signal receiving mechanism of the automatic water discharging device are shared, and the mechanism is simple. Further, in the present embodiment, the water discharge device main body 20 is detachably attached to the water discharge pipe 14, and the high-performance water faucet device of the present invention is provided by attaching the device to the existing water discharge pipe later. It can be.
