Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water discharge device with a water stopping function.

[0002]

2. Description of the Related Art As a conventional water discharge control device, as shown in FIG. 3, a shower head 2 provided on a downstream side of a mixing tap flow path 1 of a hot water mixing tap for a bathroom (not shown) is provided with a first head. On the upstream side of the on-off valve 3 of Japanese Patent Application Laid-Open No. 7-219642.
A shower device disclosed in Japanese Patent Application Laid-Open No. H10-295577 in which a constant pressure valve for water supply disclosed in the publication is provided as a second on-off valve 4 is known.

[0003] The shower head 2 is connected to a shower hose 5 at a base end and a sprinkler port 6 at a tip end.
The first opening / closing valve 3 which is opened / closed by a push button 7 as an operation element is incorporated in the middle part.

The push button 7 is fitted along a push button guide 8 and is screwed to the shower head 2 by the push button guide 8 together with the valve seat 9. Fitted inside the shower head 2,
The spring 11 is normally urged to the closing side, and is configured to abut on the valve seat 9 to seal.

[0005] The upstream side of the shower hose 5 is connected to a hot / water mixer tap via a valve case 12 in which the second on-off valve 4 is housed.

[0006] The valve case 12 is divided into an upper valve case 12a and a lower valve case 12b, which are screwed together and formed integrally. A valve seat 13 is mounted inside the upper valve case 12a at the entrance side. And a valve hole 1 in the center
The valve body 16 having the opening 5 is guided by a guide 17 and provided opposite to the valve seat 13. The valve body 16 is always urged to the open side by a spring 14, and these valve seat 13, spring 14, valve body 16 and guide 1 are provided.
The second on-off valve portion 4 is constituted by 7.

The second opening / closing valve 4 is used for controlling water shutoff / flow rate and pressure by controlling the opening / closing operation by the pressure fluctuation generated in the shower hose 5 by the opening / closing operation of the first opening / closing valve 3.

Now, the push button 7 is pushed and the first on-off valve 3 is opened.
When the is opened, the fluid is ejected from the mixing tap channel 1 through the second opening / closing valve 4 → the shower hose 5 → the first opening / closing valve 3 → the shower head 2 from the water spouting port 6.

Thereafter, when the push button 7 is pressed again to close the first on-off valve 3, the secondary pressure on the downstream side of the second on-off valve 4 sharply increases and is fitted in the valve case 12. The valve body 16 is pressed against the bias of the spring 14, and the valve body 16 abuts on the valve seat 13 to seal.

Also, due to a failure of the second on-off valve 4, etc.,
When the pressure upstream of the first on-off valve 3 rises abnormally, the pressure is used to push up the valve 10 to discharge hot water from the water spouting port 6 and release the pressure in the shower head 2.

[0011]

However, in the conventional water discharging device, the first opening / closing valve serves both as an opening / closing function and a relief valve. Therefore, a spring and a push button for setting a pressure at which the relief valve operates are used. The spring for opening and closing the first on-off valve is the same, and when the spring force is reduced, the operating pressure of the relief valve decreases, and the relief valve operates at a low pressure. For this reason, it is not possible to reduce the force of pressing the push button by reducing the spring force, and there is a problem that the operation force of the push button is heavy for the elderly and children.

Further, as disclosed in Japanese Patent Application Laid-Open No. 10-295578, if the relief valve is separately provided at a location other than the first on-off valve, the structure becomes complicated and the shower head becomes large.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an on-off button and a discharge section, and to stop water by a first on-off valve connected to the on-off button. In addition, a relief valve is provided in the first on-off valve part to absorb abnormal pressure increase on the upstream side of the first on-off valve. To provide a light and compact water discharge device with a push button type water stopping mechanism.

[0014]

In order to achieve the above-mentioned object, a water discharge device is provided in which a spring for operating a first opening / closing valve and a spring for operating a relief valve are provided in the same water passage in the first opening / closing valve portion. It is characterized by being arranged independently inside. With this arrangement, the spring force of the relief valve can be set strong, and the spring force of the first opening / closing valve operated by the push button can be set weak, so that the operating force of the push button can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the present invention will be described below.

Referring to FIGS. 1 and 2, the structure of a water discharge control device according to a first embodiment of the present invention will be described. FIGS. 1 and 2 show a case in which the water spouting device according to the present embodiment is used as a kitchen hand shower device. A shower hose 5 is connected to a shower head 2 at a base end thereof and has a decompression mechanism. The second on-off valve 4 is screwed on a connecting pipe 20 mounted on the lower part of the single lever main body 19.

The second on-off valve 4 is disclosed in Japanese Unexamined Patent Publication No. 10-2955.
No. 77, the constant pressure valve for water supply is provided as the second on-off valve 4, and the on-off operation is controlled by the pressure fluctuation generated in the shower hose 5 by the on-off operation of the first on-off valve 3,
Adjust water stoppage, flow rate and pressure.

The shower head 2 is connected to the open / close button 34 and the first open / close valve 3 that opens and closes in connection with the open / close button 34, the relief valve 18 that operates when abnormal pressure is increased, the switch button 21, and the switch button 21. It comprises a valve body 23 that moves and alternately opens and closes two valve holes 22, a shower water outlet 24, and a rectifying water outlet 25.

The first opening / closing valve 3 is opened in a state where the opening / closing valve 26 is watertightly sealed with the upstream water passage 29 by the spring seat 27 and the packing 28 and is urged downstream by the first opening / closing valve operating spring 30. The seat 31 and the valve case 32 are fitted.

The relief valve 18 is fitted in a valve case 32 and is normally urged in a closing direction by a relief valve operating spring 33.

Now, when the open / close button 34 is pressed, the shaft 35 connected to the open / close button 34 is pushed upstream, and the open / close valve 26 is pushed up from the valve seat 31 to discharge hot and cold water.

When the switch button 21 is pressed, the valve body 23 connected to the switch button 21 alternately moves on the valve hole 22 and opens and closes. Water is discharged from the rectifying water discharge port 24 or the rectifying water discharge port 25.

Then, when the open / close button 34 is pressed again, the shaft 35 connected to the open / close button 34 returns to the downstream side, and the open / close valve 26 is moved to the valve seat 31 by the bias of the first open / close valve operating spring 30. Seal by contact and stop water.

When the water pressure on the upstream side exceeds a certain pressure, the relief valve 18 is operated by the relief valve operating spring 3.
By opening against the bias of 3, water on the upstream side passes through the inside of the valve case 32 and is discharged to the downstream side, so that abnormal pressure increase can be prevented.

Also, when the first opening / closing valve or the relief valve fails, since it is integrally formed in the valve case, it can be replaced by each valve case unit, so that the maintainability is very excellent.

The above embodiment is not limited to a kitchen hand shower type single lever, but can also be applied to a shower device for a bathroom or a washroom.
