Description

[Detailed explanation of the idea] The present invention relates to a wall-embedded water supply device exclusively for bathrooms.

Conventional 1 For example, in water supply piping in bathrooms as described in Japanese Patent Publication No. 50-6986.

An operating knob for opening and closing the valve is installed only on the indoor wall, so it is difficult to open and close the valve of the water supply system.
In order to inspect, repair, or replace the valve, it is necessary to enter the bathroom where the valve opening/closing control unit is installed, which is not only inconvenient but also invades privacy in hotel bathrooms. Therefore, there was the hassle of not being able to do it without obtaining permission from the customer each time.

The purpose of this invention is to eliminate these drawbacks and to provide a bathroom in which water is discharged from a spout attached to the interior wall of the bathroom by opening and closing a valve that is embedded in the bathroom wall and is operated from inside the bathroom. To open and close a valve of a water supply device for a bathroom outside the bathroom, and to recognize the water supply status accompanying the opening and closing of the valve from the outside across the wall of the bathroom,
It is an object of the present invention to provide a built-in three-way operating pulp that allows valves to be inspected, repaired, replaced, etc. from outside the bathroom without entering the bathroom, and at the same time is easy to assemble and repair. The gist of the structure is a valve seat provided in the middle of a flow path that connects the inlet and outlet, and two openings coaxially arranged on both sides sandwiching the valve seat. and a valve body buried in the bathroom wall with one opening of the two openings opening on the inside wall of the bathroom and the other opening opening on the outside wall of the bathroom, and A discharge port is installed on the inner wall of the bathroom in communication, and a rectangular fitting is attached to one of the openings so as to be rotatable but not axially movable relative to the valve body. A main spindle provided with a convex portion or a fitting recess, and a guide screw provided in the other opening are screwed together so as to be movable in the axial direction, and the end inserted into the main body approaches and separates from the valve seat. a sub-spindle to which a valve body is fixed, one end of which is fixed to the end inserted into the main body of the sub-spindle and extends forward from the front face of the valve body through the valve seat opening of the valve seat; A connecting member is formed at the end thereof with a rectangular fitting recess or fitting protrusion that is axially removably fitted into the fitting protrusion or fitting recess at the end of the main spindle and cannot rotate with respect to the other; a normal operation handle disposed on the inner wall surface and attached to the end of the main spindle extending outward from the main body; and a normal operation handle disposed on the outer wall surface of the bathroom and attached to the end of the sub spindle extending outward from the main body. The temporary operation handle installed on the inside of the bathroom wall and the normal operation handle installed on the inside are interlocked with each other. Not only can you control the opening and closing of the valve by operating the operating handle, but you can also recognize the opening degree of the valve, and the sub-spindle attached to the valve body can be used independently for work outside the bathroom, regardless of the main spindle. By having a structure that allows the valve to be removed from the valve body, it is possible to remove the valve from the bathroom wall, compared to a water supply system that is embedded in the bathroom wall and where normal valve opening and closing operations are performed in the bathroom.
This makes it possible to open, close, and adjust the valves from outside the bathroom, and to perform failure inspection, repair, and replacement from outside the bathroom.

Examples will be described below based on the drawings.

The drawing shows an embodiment of the water supply device of the present invention and how it is installed on the wall of a bathroom and used to supply mixed water to the bathtub.The drawing shows an example of the water supply device of the present invention and how it is used to supply mixed water to the bathtub.・One side is the normal operation part on the bathroom side, and the other side is the temporary operation part on the inspection side.

In the figure, a is a hot water pipe, b is a water pipe, C is a mixed water outlet, d is a bathroom wall, 1 is a valve body, 2 and 3 are a sub spindle and a main spindle, which are opposed to each other. 4 is a valve body at the tip of the sub spindle 2, 5 is a valve seat, 6 is a valve seat opening, 19 and 20 are an inlet and an outlet, which are provided in the middle of the flow path connecting both eyes. There are two openings provided coaxially on both sides with the valve seat 5 in between, one opening opening to the outside of the bathtub and the other opening opening to the inside of the bathroom.

Reference numeral 7 denotes a connecting member fixed to the tip of the sub-spindle 2 so as to protrude from the front face of the valve body 4 and extends through the valve seat opening 6. Reference numeral 8 indicates a connecting member of the sub-spindle 2 that protrudes from the one opening of the sub-spindle 2. A pin fixed to the tip, 9 is a rectangular fitting recess for fitting the spindle, and 10 is provided at the tip of the main spindle 3 protruding from the other opening.
A rectangular fitting protrusion that is axially removable and non-rotatable.

11 is a mounting bracket for watertightly screwing the sub spindle 2 onto the main body 1; 12 is a guide screw; 13 is a mounting bracket for watertightly and rotatably mounting the main spindle 3 on the main body 1; 14; 15. is a part of the mounting bracket and is a stopper plate for preventing the main spindle 3 from moving in the axial direction;
Reference numeral 16 indicates a handle for the bathroom fullll (normal operation), 1 inspection side (temporary operation), which is attached to the operating portion protruding from the walls of the sub and main spindles 2 and 3, respectively.17.18 indicates a cover.

In this embodiment, hot water or water is sent from hot water pipe A and water pipe A, and after adjusting the flow rate by the three-way operating pulp of the present invention, the water is mixed, and the water is sent to the bathtub through the mixed water outlet C. During normal use, the amount of hot water and water can be adjusted by rotating the handle 15 for normal operation on the bathroom side, and the main spindle 3 will rotate, and the spindle will rotate 30 times via the connecting member 7 fitted to the tip. When the spindle 2 rotates, the secondary spindle 2 moves in the axial direction because it is in a screwed state with the main body 1, and the valve body 4 attached to the tip of the spindle rotates. The distance from the valve seat 5 can be adjusted, and the valve can be opened and closed.

At this time, even if the sub spindle 2 moves in the axial direction, the main spindle 3 is prevented from moving axially by the stopper plate 14, and the axial movement of the connecting member 7 is prevented between the fitting convex portion 10 at the tip of the main spindle 3 and the sub spindle 2. It is possible to escape by simply changing the depth of insertion into the recess.

Therefore, when the handle 15 for normal operation on the bathroom side is rotated, the inspection side temporary operation handle 16 on the outdoor side also rotates and moves back and forth in the axial direction, making it possible to check the opening/closing degree from the inspection side by the degree of movement. You can do it.

Next, when it is necessary to operate from the 9 inspection side, all you have to do is rotate the temporary operation handle 16, and when the handle 16 is rotated, the sub spindle 2 screwed with the main body 1 will rotate in the axial direction. The valve body 4 can be opened and closed by moving.

In this case, the normal operation handle 15 on the bathroom side rotates but does not move forward or backward in the axial direction.

In addition, both spindles 2 and 3 can be disassembled into two pieces by the fitting part of the connecting member 7, and each spindle 2 and 3 can also be disassembled from the main body 1, making disassembly and assembly for inspection and repair easy.
And it can be done in a short time.

According to the water supply device of the present invention having the above configuration,
The following useful effects can be obtained.

■ A main spindle for opening and closing the valve using a normal operation handle installed inside the bathroom, and a sub-spindle for opening and closing the valve using a temporary operation handle installed outside the bathroom.

Since they are removably connected in the axial direction via the connecting member, the main spindle and the sub spindle can be installed and removed separately for each corresponding opening, and the valve of the device can be attached or removed separately. Assemble the device by disassembling it into two parts, including the operating section.

Not only is it easy to install, but even if it is a water supply system that is embedded inside the wall, it is difficult to check the valve unless it is from inside the bathroom. There is no inconvenience of not being able to repair or replace the valve.If you remove the sub spindle from the valve body outside the bathroom, you can easily inspect and repair the valve without having to enter the bathroom and touch the main spindle. , can be done interchangeably.

■ The inner end of the sub-spindle, which is operated by a temporary operating handle installed on the outside wall of the bathroom, and the inner end of the main spindle, which is operated using a normal operating handle installed on the inner wall, are not connected by screws, but have a rectangular fitting recess. Can be attached and detached in the axial direction by mating.

They are connected so that they cannot rotate with each other, so there is no risk of the spindles becoming uncoupled as the main spindle and sub spindle rotate, so normal operations from inside the bathroom and temporary operations from outside the bathroom are possible. The opening and closing of the valve can be controlled reliably and precisely by any operation of the handle, and since the sub spindle moves axially with respect to the valve body as it rotates, it is possible to control the opening and closing of the valve from outside the bathroom. To accurately recognize the open/closed state of a valve by the moving position of a temporary operation handle attached to the outer end of a sub-spindle, even though the state of water being discharged from a water spout provided on a wall cannot be directly observed. I can do it.

Furthermore, since it is a built-in valve, there is no inconvenience like conventional valves that require installation and replacement from only one side, and it is possible to have a structure in which one functional part can be disassembled into two. construction.

This has the effect of facilitating repair and assembly.
