BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch faucet attached to a hot and cold water mixing tap.

[0002]

2. Description of the Related Art Conventionally, hot and cold water mixing taps have been mounted on the walls of kitchens and bathrooms, and are arranged in a V shape on the water pipes and hot water pipes embedded in the walls. 1
It is connected via a pair of crank pipes (also referred to as sockets or eccentric pipes), and hot water is spouted from one spout capable of swinging.

By the way, a hot water tap is incorporated in such a mixing tap, and when the handle is operated, the hot water is passed not through the spout but through, for example, the shower head to discharge the water (actually). JP-A-59-34764,
JP-B-58-19425, JP-B-58-3334
No. 1, etc.).

A branch faucet for branching only water is not incorporated in the mixing tap, and if only water is to be spouted, only water will be spouted from the spout by operating the handle. Therefore, in the prior art, as shown in FIG. 4, among the pair of water supply and hot water supply crank pipes 1, a branch water faucet 2 is attached to the water supply crank pipe 1, and the water is branched from here, for example, purified water. I am trying to connect to the vessel 3. In FIG. 4, 4 is a hot and cold water mixing stopper, 5 is a spout, and 6 is a connecting pipe.

However, in the crank pipe 1 provided with such a branch faucet 2, the branch faucet 2 is arranged so as to project forward in a direction orthogonal to the wall surface. Since it is located directly under the spout 5, it may interfere with the swinging of the spout 5, hinder the installation of a container for receiving water spouted from the spout 5, and the existing mixing stopper 4
If a branch faucet 2 is to be newly attached to the above, there is a problem that the crank pipe 1 also needs to be replaced.

[0006]

Therefore, the present invention has been made to solve the above problems, and the gist of the present invention is to provide a water pipe and a hot water pipe embedded in a wall in a V shape. Connected via a pair of crank tubes arranged,
Also, in a hot and cold water mixing tap having a swingable spout, a branch tap having a valve rod with a handle parallel to the wall surface at the outlet of the water supply crank pipe and having a branch passage opened downward is provided. Provided at the outlet of the hot water supply crank pipe was an adapter composed of a short pipe having the same length as the length of the branch faucet in the direction of the main pipe line, and the hot and cold water mixing stopper was attached to these branch faucet and adapter. This is a branch faucet attached to a hot and cold water mixing tap.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 (A) is a sectional view of a branch faucet of an embodiment of the present invention, FIG. 1 (B) is a sectional view taken along the line aa of FIG. 1 (A), FIG. It is a top view of an example.

First, the overall outline of this embodiment will be described. Figure 3
In the figure, reference numeral 4 denotes a single lever type hot and cold water mixing tap, to which a relatively long spout 5 is attached so as to be swingable. The mixing plug 4 is attached to the wall surface 7 of the kitchen through a pair of water supply and hot water supply crank pipes 1 and 1a.

At the outlet of the water supply crank pipe 1, a valve rod 24 of a compression type branch faucet 2a is provided parallel to the wall surface 7, that is, in the vertical direction, and the outlet of the hot water supply crank pipe 1a is provided. The adapter 8 is provided with a short pipe having the same length as the length of the branch faucet 2a in the main pipe line direction. Therefore, the mixing stopper 4 is attached to the branch faucet 2 a and the adapter 8. As a result, branch tap 2
The handle 9 of a and the hose (not shown) branched and connected from the branch faucet 2 a are arranged on the back side of the mixing tap 4.

The branch faucet 2a is a compression type faucet which is opened and closed by a kerep 22, and is a branch valve having a horizontal main pipe line and a downward branch line. The valve body 10 is provided with first, second and third communication holes 11, 12, 13.

The socket 1 is provided in the opening of the first communication hole 11.
4 is screwed, and the cap nut 15 is attached to the socket 14.
Is retained and is rotatably fitted. A nut 16 is screwed into the opening of the second communication hole 12. The first and second communication holes 11 and 12 form a main pipe line (19) in a direction orthogonal to the wall surface 7.

A joint short tube 17 is screwed into the opening of the third communication hole 13. Then, the third communication hole 13
Forms a downward branch path (13) parallel to the wall surface 7.

The cap nut 15 of the first communication hole 11 is adapted to be connected to the water inlet of the mixing stopper 4, and the nut 16 of the second communication hole 12 is the cap nut 1 of the water supply crank pipe 1.
It is designed to connect with 8. In addition, the third communication hole 1
A hose connected to a water purifier (not shown) is fitted onto the joint short pipe 17 of No. 3.

These first and second communication holes 11, 1
Reference numeral 2 forms a primary chamber 19 penetrating the valve body 10 in the horizontal direction, and the third communication hole 13 communicates with a jacket-shaped secondary chamber 20 formed outside the primary chamber 19. Therefore, the length of the main pipeline can be made as short as possible.
The primary chamber 19 and the secondary chamber 20 communicate with each other through a valve hole 21, and the valve hole 21 is opened and closed by a kelep 22.

The kelp 22 is constantly pressed by the spring 23 supported by the valve rod 24 to close the valve hole 21. The foot 22a of the kelep 22 is vertically slidably inserted into the lower end side of the valve rod 24. The valve rod 24 is screwed to the valve body 10 by a screw 25, and the handle 9
When the valve is rotated, the valve rod 24 is screwed up and down, and the kerep 22
Is brought into a state where it can be moved up and down by water pressure and the spring 23.

On the other hand, the adapter 8 attached to the hot water supply crank pipe 1a has a screw 2 at one end of the adapter body 26.
7 is provided, and the socket 28 is screwed to the other end side. A cap nut 29 for an adapter is secured to the socket 28 so as to be freely rotatable. This adapter cap nut 29 is adapted to be connected to the hot water inlet of the mixing tap 4,
The screw 27 is connected to the cap nut 30 of the hot water supply crank pipe 1a. Incidentally, 31 is a single lever of the mixing stopper 4.

The operation of this embodiment will be described. The existing hot and cold water mixing plug 4 is removed from the pair of crank pipes 1 and 1a, the branch water faucet 2a is attached to the water supply crank pipe 1, and the adapter 8 is attached to the hot water supply crank pipe 1a. , Reattach to the branch faucet 2a and the adapter 8.

The third communication hole 13 of the branch faucet 2a
To the hose connected to the washing machine or the water purifier. By rotating the handle 9 of the branch faucet 2a, water can be supplied to a washing machine or the like even when the mixing tap 4 is in use. Even if the branch faucet 2a is provided, the spout 5 of the mixing tap 4 can be swung. There is no hindrance.

EFFECTS OF THE INVENTION According to the present invention, 1) The branch faucet is provided on the back side of the hot and cold water mixing tap, and the handle of the branch faucet is provided parallel to the wall surface. Even if a new one is added, it does not hinder the swinging of the spout with the hot and cold water mixing tap. 2) Existing crank pipes for hot and cold water supply and hot and cold water mixing taps can be used as they are, so the cost of adding branch taps can be reduced. 3) Even if a branch faucet fails, it can be replaced regardless of the crank pipe or the hot and cold water mixing tap. 4) There is no damage to the wall because the crank pipe is left as it is when a new branch faucet is added.
