Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure in which another faucet can be easily connected and attached to a hot and cold water mixing tap having a wall-fixing leg tube.

[0002]

[Prior Art]

 A hot and cold water mixing tap for fixing a wall is generally one that fixes the main body by connecting it to each of the water supply pipe and the supply pipe for hot water supply that are piped in the wall, and at the same time connects the flow path. Then, for connection with these supply pipes, leg pipes for water supply and hot water supply are provided at the back of the main body to position and fix the main body to the wall.

On the other hand, facilities around various types of faucets have recently been expanded, and, for example, when used as faucets for kitchens, water purifiers have been widely provided. This water purifier is a simple type that removes water that flows freely by detaching from the tip of the water discharge pipe of the faucet, as well as a new supply pipe branched from the supply pipe to the main body of the hot and cold water mixing tap. There is one that can be used independently from the main body by connecting.

When the latter water purifier is newly attached to the hot and cold water mixing tap, a new water supply pipe is provided on the building side, or a flow path from the leg pipe for water supply of the hot and cold water mixing tap to the water purifier is connected. Will be done.

However, it is difficult to newly install a water supply pipe in a general household or an apartment house. Even when using the leg pipe of the hot and cold water mixer tap, it cannot be used as a branch fitting because the leg pipe is exclusively for connecting the flow path to the hot and cold water mixer tap. Therefore, in order to connect the pipe to the water purifier, it is necessary to separately provide a branch fitting on the leg pipe for water supply.

An example of such a branch fitting is disclosed in Japanese Utility Model Laid-Open No. 1-136561. This is because a branch fitting for connecting the flow path to a water purifier etc. is installed between the leg pipe on the water side and the building's supply pipe, and the main body of the hot and cold water mixing tap comes out in front of the installed part. This is a piping structure in which a connection socket is added between the side leg pipe and the building supply pipe.

[0007]

[Problems to be solved by the device]

 When newly connecting a water purifier to an existing hot and cold water mixing tap, in order to install a branch metal fitting and a connection socket, remove each of the water side and hot water side leg pipes from the supply pipe on the building side and then connect the branch metal fitting. It is a construction to connect the connection socket with a pipe. For this reason, when removing the leg pipe from the supply pipe on the building side, it is necessary to peel off the wall tiles or, in the case of a concrete wall, to partially scrape off the tiles. Also, after connecting the pipes, the wall must be repaired. In this way, if a branch metal fitting or a connection socket is newly installed in the leg pipe, not only the work at the site is troublesome, but also the supply pipe in the wall may be damaged or the position may move. Problems of water leakage after construction are likely to occur. Also, since the branch fitting and the connection socket are separate entities, if the tightening degree between the leg pipes and the supply pipe on the building side is not adjusted, the entire pipe is likely to be distorted. From this, not only the workability is greatly deteriorated, but also when the hot and cold water mixing valve is loaded during use, there is a high risk of water leakage.

The problem to be solved in the present invention is to easily perform piping work from one existing hot and cold water mixing tap to another faucet, and to prevent leakage of water after construction.

[0009]

[Means for Solving the Problems]

 The present invention relates to a hot and cold water mixing plug including a main body and two leg pipes that are connected to a back portion of the main body and are connected to water supply and hot water supply pipes on a building side such as a wall. Between the hot water supply pipe and the hot water supply pipe, the pipe adapter is detachably incorporated to communicate with the main body, and the pipe adapter communicates with the flow passage from the water supply pipe to mix the hot water and the hot water. The feature is that a faucet other than the faucet can be connected.

[0010]

[Action]

 The main body of the existing hot and cold water mixing valve is connected to the water supply and hot water supply pipes on the side of the building such as a wall by connecting the leg pipes on the back of the main pipe to connect the flow path and is fixed to the wall. Therefore, if the pipe adapter is installed between the leg pipe and the main body after removing only the main body from the leg pipe while keeping the leg pipe connected to the hot water supply pipe and hot water supply pipe, it is not necessary to pull out the leg pipe from the pipe on the building side. .. Further, since another water faucet can be connected to the pipe adapter, the water supply to the hot and cold water mixing faucet can be branched and supplied to another water faucet.

【Example】

 FIG. 1 is a cutaway plan view showing an example in which the faucet mounting structure of the present invention is applied between a hot and cold water mixing tap and a water purifier, and FIG. 2 is a front view thereof.

In the figure, the body 1 of the hot and cold water mixing tap has the same structure as that conventionally used, and at the time of the existing installation, the water leg pipes 2 and the hot water leg pipes 3 are respectively attached to the backs thereof. It is used by connecting to the mounting seats 4 and 5 of the section. That is, similar to a normal wall-fixing type hot and cold water mixing tap, a product in which the leg pipes 2 and 3 are connected to the back of the main body 1 is shipped as a product, and is already piped in the wall 50 of the building at the site. The leg pipes 2 and 3 are connected to a water supply pipe 51 and a hot water supply pipe (not shown), respectively, and the inside of the main body 1 is connected to the water supply source and the hot water supply source and fixed to the wall 50. For the connection, the cap nut 2a of the leg pipe 2 is screwed to the male screw 4a provided on the mounting seat 4 on the water side, and the cap nut 3a of the leg pipe 3 is similarly mounted on the hot water side. It is carried out by screw-joining with the male screw 5a of No. 5. It should be noted that the leg pipes 2 and 3 are equipped with a water stopcock for adjusting the water supply pressure and the supply pressure from the hot water supply source, and for stopping water at the time of maintenance and inspection as in the conventional case.

In the illustrated example, a water purifier 6 is newly provided on the right side of the main body 1 in addition to the main body 1 of the hot and cold water mixing tap. In addition, the water purifier 6 is attached to the main body 1 of the existing hot and cold water mixing tap, by branching the flow path from the water supply pipe 51 from the flow path toward the main body 1 of the hot and water mixing tap and connecting it to the wall 50. This is done using the piping adapter 7 for fixing. The water purifier 6 has a replaceable filter housed therein, and as shown in FIG. 2, has a structure including a handle 6a for opening and closing a flow path and a water discharge pipe 6b.

FIG. 3 is a cross-sectional view of the pipe adapter 7.

As shown in FIG. 1, the pipe adapter 7 is supported at two points by using the mounting seats 4 and 5 on the water side and the hot water side of the back of the body 1 of the hot and cold water mixing stopper, and protrudes rightward from the body 1 to The back of the water purifier 6 can be connected to the right end. The left half portion of the pipe adapter 7 is provided with connecting ports 7a and 7b capable of aligning with the mounting seats 4 and 5 of the body 1 of the hot and cold water mixing stopper as female screw holes protruding to the front side. Inflow ports 7c and 7d that are coaxial with 7b are provided on the back side.

As shown in FIG. 1, bushings 8 are screwed into and fixed to the connection ports 7a and 7b, respectively, so that the bush nuts 8 can be used to connect to the main body 1 with a cap nut 9. .. Each of the inflow ports 7c and 7d is formed by engraving a male screw 7e on the outer peripheral surface, and the cap nuts 2a and 3a of the leg pipes 2 and 3 can be screwed into the male screw 7e. Further, a partition wall 7f is provided in a substantially middle portion between the inlets 7c and 7d, and water from the inlet 7c is supplied to the water chamber in the body 1 of the hot and cold water mixing tap and the water purifier 6 side, and the other inlet The hot water from 7d is supplied to the hot water chamber side of the main body 1 without being mixed with water in the pipe adapter 7.

On the other hand, a connection port 7g for communicating and connecting the water purifier 6 is opened as a female screw hole on the front surface of the right end portion of the pipe adapter 7. A sleeve 7h that wraps around the back portion of the water purifier 6 is provided around the connection port 7g so as to project forward.

FIG. 4 is a cross-sectional view showing a connection structure between the water purifier 6 and the pipe adapter 7.

The back of the water purifier 6 has a cylindrical shape with an outer diameter that fits into the sleeve 7h, and its rear end wall communicates with the internal flow passage and can be screwed into the connection port 7g of the pipe adapter 7. The short tube 6c is protruding. Then, by screwing the short pipe 6c into the connection port 7g and fixing the water purifier 6 so that the posture of the water purifier 6 is correct as shown in FIG. 2, the water supply from the water supply pipe 51 via the pipe adapter 7 is performed. A water purifier 6 can be connected to the path.

Here, the water purifier 6 is newly installed by the pipe adapter 7 to the existing equipment in which the leg pipes 2 and 3 are respectively connected to the main body 1 by the cap nuts 2a and 3a and connected to the pipes on the building side. The points are as follows.

First, the cap nuts 2 a and 3 a screwed to the mounting seats 4 and 5 of the main body 1 are loosened, and the main body 1 is removed from the leg tubes 2 and 3. At this time, both the water side and the hot water side leg pipes 2 and 3 are still connected to the building side pipes, and it is not necessary to pull out the leg pipe 2 from the water supply pipe 51 in FIG. 1, for example.

Next, when the cap nuts 2a and 3a are screwed into the male screws 7e of the inflow ports 7c and 7d with respect to the leg pipes 2 and 3, the pipe adapter 7 is connected to these leg pipes 2 and 3 at the same time. , The water-side and hot-water-side channels are connected. When the cap nuts 9 are screwed into the male screws 4a and 5a of the mounting seats 4 and 5 of the body 1 of the hot and cold water mixing tap, the body 1 is connected to the pipe adapter 7 and the water side and hot side flow paths are also connected. To be done.

Further, with respect to the fixed pipe adapter 7, the back side of the water purifier 6 is inserted into the sleeve 7h, and the short pipe 6c is screwed into the connection port 7g. Then, the water purifier 6 is fixed to the pipe adapter 7 by adjusting the screwing amount properly and making the posture of the water purifier 6 correct as shown in FIG. The water purifier 6 may be connected to the pipe adapter 7 in advance, and the water purifier 6 may be used between the leg pipes 2 and 3 and the main body 1 of the hot and cold water mixing stopper as a work procedure.

As described above, the water purifier 6 can be attached to the existing hot and cold water mixing tap by inserting the pipe adapter 7 between the leg pipes 2 and 3 and the main body 1 after removing only the main body 1. .. For this reason, compared with the construction in which the leg pipes are separated as described in the prior art, the steps of removing the tiles of the wall 60 and repairing after construction are eliminated. Further, since the water supply pipe 51 and the hot water supply pipe on the building side are not screwed or their positions are not moved, the occurrence of water leakage after construction is prevented.

The pipe adapter 7 is supported at two points between the water-side and hot-water side leg pipes 2 and 3 and the main body 1, and the water purifier 6 is extended on the line segment connecting these support points. To position. Therefore, even if the water purifier 6 is provided at the end of the pipe adapter 7, the posture of the pipe adapter 7 does not tilt, and even if the water purifier 6 has a large weight, the pipe may be distorted. Absent. Therefore, the pipe adapter 7 can maintain a stable posture even with respect to the load when the handle 6a of the water purifier 6 is operated, and there is no fear of occurrence of pipe distortion or water leakage.
