2. Description of the Related Art Heretofore, as a water spouting device for spouting water from a spouting port and stopping water by operating a spouting water stop operating part, a device in which the spouting water stop operating part is a seesaw type switch operating part is known. is there. FIG. 7 shows an example thereof. In the figure, reference numeral 200 is a water spout, 202 is a water spout operation unit for spouting and stopping water from the water spout 200, and this water spout operation unit 202 is configured as a seesaw-type switch operation unit. There is.

In the case of this water spouting device, the water spouting stop operation section 202
When one end 202a is pushed, water is discharged from the water outlet 200, and when the other end 202b is pushed, water is stopped from the water outlet 200, that is, water is stopped.

Specifically, in the case of this water discharge device, the main water channel 2
A main valve 206 made up of a diaphragm valve is provided on 04, and a back pressure chamber 208 is formed on the back side of the main valve 206. As shown in FIG. 7A, the main valve 206 is normally held in a valve seat 210, that is, in a valve closed state by the water pressure in the back pressure chamber 208.

The back pressure chamber 208 is adapted to communicate with the downstream portion of the main valve 206 in the main water channel 204 by the pilot water channel 212, and the pilot water channel 21.
2 is opened and closed by the pilot valve 214.

In the case of this water spouting device, the water spouting stop operation section 202
When the one end portion 202a in FIG.
As shown in FIG. 4, the pilot valve 214 is lifted upward and the pilot water channel 212 is in communication, that is, the back pressure chamber 20.
8 is in communication with the main water channel 204, specifically, with the downstream portion of the main valve 206 in the main water channel 204, and the back pressure chamber 208
The water inside flows out into the main water channel 204, and the pressing action of the main valve 206 in the valve closing direction by the water pressure in the back pressure chamber 208 is released. As a result, the main valve 206 is opened by the water supply pressure of the main water passage 204, and here, water is discharged from the water discharge port 200 to the outside through the main water passage 204.

The end 202 on the side opposite to the one end 202a
When b is pushed in, the pilot valve 214 is pushed downward as shown in (A), and the pilot water passage 212 is shut off, where the water in the main water passage 204 is a small hole (not shown) through which the main valve 206 penetrates. Through the back pressure chamber 208
The water pressure in the back pressure chamber 208 increases, and the water pressure causes the main valve 206 to close and the water discharge from the water discharge port 200 is stopped.

In the case of this water spouting device, the water spouting stop unit 202
Since it is configured as a seesaw-type switch operation unit, it is possible to perform water discharge and water stop by simply pushing the switch operation unit, which is highly convenient.

FIG. 8 shows another type of water spouting device proposed by the present applicant, and this water spouting device 215 also has a water spouting operation unit 202 as a similar seesaw type switch operation unit. The water discharger 215 has a main body 216, and a discharge / stop water operation section 202 is provided as a seesaw-type switch operation section at the upper end of the main body 216 in the figure, and the main body 216 is provided on the opposite side. A water discharge port 200, a main water channel 204, a connection port 205 of a pipe for supplying water to the water discharge port 200, and the like are provided.

The body body 216 is also provided with a pilot valve 214 on the side of the discharge / stop water operation section 202. In the figure, reference numeral 218 denotes a small through hole provided in the main valve 206, and the water in the main water channel 204 is introduced into the back pressure chamber 208 little by little through the small hole 218.

[0011]

This water discharge device 215
Is attached, for example, to the wall of the bathroom in the bathroom (at this time, the outlet 200 is attached downward)
used. Specifically, it is used by being attached to a wall or the like of a washroom in a state where the spouting / stopping water operation unit 202 is exposed to the inside of the room and other portions including the main body body 216 are hidden behind the wall.
