DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water mixer tap, in which a hot water supply pipe connecting member having a check valve is fixed to a wall surface so that the distance from the wall surface can be adjusted. The present invention relates to a hot water supply side fixing device.

[0002]

2. Description of the Related Art In order to install a hot / water mixer tap on a wall surface, a hot water supply pipe is often disposed in parallel with the surface of the wall near an existing water supply pipe provided in the wall. is there. this is,
If the hot water supply pipe is also provided in the wall, the piping work becomes large and the construction cost is high, so this method is adopted instead of such a construction method.

In the case of this construction method, conventionally, as shown in FIG. 4, an inverted L-shaped pipe fixing member (32) is screwed on the surface of a wall (31).
, And connect the hot water supply pipe (34) to the lower end of the vertical part,
Connect the check valve (36) of the hot water mixer tap (35) to the tip of the horizontal part,
In addition, the water supply port of the hot-water mixer tap is connected to the tip of an existing water supply pipe provided in the wall via a connecting member called Zarbo.

[0004]

However, in the structure shown in FIG. 4, the distance from the surface of the wall (31) to the check valve (36) is constant on the hot water side and cannot be adjusted. Check valve from surface of wall (31) by zalvo on water side as above
The distance to (36) was adjusted to match the distance on the hot water side.

When the check valve (36) of the hot and cold water mixing tap (35) is connected to the horizontal portion of the inverted L-shaped pipe fixing member (32), the check valve
It is necessary to wrap a seal tape around the male screw part (37) of (36) and then screw the male screw part into the female screw part (38) of the horizontal part of the pipe fixing member (32). It became something.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to fix a hot water supply pipe connecting member provided with a check valve to a wall surface so that a distance from the wall surface can be adjusted. It is an object of the present invention to provide a hot water supply side fixing device for a hot water mixing tap.

[0007]

SUMMARY OF THE INVENTION The present invention has been devised in order to achieve the above object, and has a cylindrical projection projecting rearward from a hot water supply pipe connecting member (2) having a check valve (1) therein. On the other hand, a pipe fixing member (4) having a forward-facing cylindrical projection (4a) is fixed to the wall surface, and a hot water supply pipe connecting member (2) is provided.
Male thread (5) is engraved on the outer peripheral surface of the projection (2a) of
A female screw (6) is engraved on the inner peripheral surface of the protrusion (4a) of the member (4), and by adjusting the screwing distance of the male screw (5) into the female screw (6), the hot water supply pipe from the wall surface is adjusted. It is fixed so that the distance to the connecting member (2) can be adjusted,
It is a hot water supply side fixing device in a hot water mixer tap.

In general, the hot water mixer tap is provided on a hot water check valve provided on the hot water supply side, a hot water quantity control valve provided on the water discharge side of the hot water check valve, that is, on the downstream side, and on the water supply side. A water-side check valve, a water flow control valve provided on a water discharge side of the water-side check valve, that is, a downstream side, a hot-water mixing chamber provided between the hot-water control valve and the water flow control valve, and a hot-water mixing chamber and And a mixed liquid amount control valve provided between the water ports.

In a preferred embodiment, a hot water supply pipe connecting member
The protrusion (2a) of (2) is a cylindrical rear protrusion having an external thread portion (5) on the outer peripheral surface thereof, and the protrusion (4a) of the pipe fixing member (4) has a cylindrical front protrusion. A protrusion, and a female screw portion (6) on its inner peripheral surface
Having. The hot water supply pipe connecting member (2) is fixed at a required position to the pipe fixing member (4) by screwing the male thread (5) into the female thread (6) of the pipe fixing member (4). .

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described with reference to embodiments.

Embodiment 1 In FIGS. 1 to 3, a hot water supply pipe connecting member (2) for connecting a hot water supply pipe to a hot water inlet of a hot water mixer tap is vertically arranged,
A check valve (1) is installed at the upper end. Hot water supply pipe connection member
A rear projection (2a) having a cylindrical shape is provided at a rear portion near the lower end of (2), and a male screw portion (5) is engraved on the outer peripheral surface of the rear projection (2a).

On the other hand, the wall (3) where the hot and cold water mixing tap is to be installed is composed of a fixed disk (4b) and a cylindrical front projection (4a) provided concentrically at the center of the fixed disk (4b). Become a pipe fixing member (4)
Are fixed by screws (10) at the fixed disk portion (4b). A female screw portion (6) is engraved on the inner peripheral surface of the front projection (4a) of the pipe fixing member (4).

The hot water supply pipe connecting member (2) is fixed to the pipe fixing member (4) by screwing the male thread (5) into the female thread (6) of the pipe fixing member (4). Wall (3)
The distance from the hot water supply pipe connecting member (2) to the male thread (5)
Adjusting the screwing distance of the female thread (6)
It is adjusted to match the distance from (3) to the water supply pipe connection member. After this adjustment, the male thread (5) and female thread
The screwed portion of (6) is fixed by screws (11). A hot water supply pipe (7) is connected to a lower end of the hot water supply pipe connecting member (2), and a hot water inlet (9) of a hot and cold water mixing tap (8) is connected to a front upper end.

[0014]

As described above, the pipe arranging device in the hot and cold water mixing tap according to the present invention is configured as described above, so that the distance from the wall surface to the hot water supply pipe connecting member provided with the check valve can be adjusted on the hot water side. It can be fixed to the wall surface as it can. In addition, the work of attaching the hot and cold water mixing tap can be performed much easier.
