When performing maintenance or replacement of the strainer 44, the valve seat 26 is closed, and then the cap 43 for the water stopcock integrated with the strainer 44 is moved to the functional body 12.
To the side of the. At this time, the empty space 14 on both sides of the functional body 12 can be used as a space for attaching and detaching the strainer 44 and the like, and the strainer 44 and the like can be attached and detached while leaving the water stopcock 41 with the flow path closed. This attaching / detaching operation is not only easy but also can be performed safely.
In this example, the water stopcock 41 is incorporated into the functional body 12 as the water stoppage unit 40 with the strainer 44 integrated, but these may be incorporated separately. However, if the water stopcock 41 and the strainer 44 are integrated as in this example,
Maintenance work is facilitated, and the maintenance space of the strainer 44 as well as the operation space of the water stopcock 41 can be used also as the operation space of the operation handle 1D, so that the space around the water tap 10 can be effectively utilized. It is effective.

By the way, the so-called deck-type hydrant is
As described above, the hydrant is only for the deck type, but a so-called wall-mounted hydrant can also be used for the deck type. For example, it is known that a substantially inverted L-shaped connection support tube is set up on a deck surface, and a connection portion on a back surface of the main body is connected and fixed to the connection support tube to be used as a deck type. The water faucet according to the present invention is basically intended to be used as a wall-mounted type, but by using the connection support pipe as described above, it can also be used as a deck type. is there. Here, when the water tap according to the present invention is used as a deck type, the following advantages are obtained.

Since a simple and compact connecting support tube having no water stopcock can be used, the space for the connecting support tube on the rear side of the main body can be easily reduced. Further, since there is no need to secure a space for operating the water stopcock below the main body, a part of the connection support pipe can be arranged below the main body. Thereby, the space below the main body can be effectively utilized. In addition, since the connection support tube may be partially disposed below the main body, the degree of freedom of the form of the connection support tube itself can be improved. Further, since it is possible to cover the space below the main body (functional body) with a cover, substantially the entire connection support pipe and the main body (functional body) are covered with the cover, and the entire faucet is It is also easy to adopt a configuration mounted on the deck surface. In this case, it is not necessary to provide an opening or the like for exposing the space below the main body (functional body) on the front side of the cover, so that it is easy to improve the design of the entire cover.

[0048]

As described above, according to the present invention, the space below the main body can be effectively used, the operation and maintenance of the water stopcock are safe and easy, and the amount of protrusion from the wall surface is large. A water tap with a wall which can improve the aesthetic appearance while reducing the amount of water can be obtained.
