Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded water faucet which is used for a washing machine or for water sprinkling, and which suppresses a protrusion from a mounting surface.

Conventionally, as this type of embedded water faucet, one disclosed in Japanese Patent Application Laid-Open No. H11-280127 is known.
In this device, a connecting portion of a rising water supply pipe, a water discharge port, and a flow path that opens and closes in the middle of a flow path connecting the water supply pipe connection section and the water discharge port in an embedded box having an open front surface. A water faucet having an open / close valve portion is stored, and a spout port and an open / close spindle of the open / close valve portion are protruded from a cover covering the opening portion. Are connected by a coupler.

However, when the conventional embedded water faucet is used for supplying water to a fully automatic washing machine or the like, when it is installed above the mounting surface, the flexible tube comes into contact with an opening / closing operation section such as a spindle, and the opening / closing operation is performed. It is difficult and the flexible tube breaks.

Further, since the water supply pipe is generally set up from below the floor or the like, the flow path of the faucet is formed in a substantially inverted U-shape so that the connection part of the water supply pipe and the water discharge port face downward. Must be configured.

In this case, if the faucet flow path is configured such that the connection part of the water supply pipe is located on the back side of the mounting surface and the water discharge port is located on the front side, the depth dimension of the embedding box becomes long. When the wall thickness is thin, there are cases where it cannot be installed.

In view of this, it is conceivable that the connecting portion of the water supply pipe and the water outlet are provided side by side in parallel with the mounting surface. However, the installation position of the opening / closing operation portion is determined when the opening / closing operation portion hits the water outlet during opening / closing operation. When the opening / closing operation unit is installed on the vertical line of the water spout, the vertical dimension of the embedding box becomes smaller, and when the opening / closing operation unit is installed on the horizontal line of the water spout, the horizontal dimension of the embedding box becomes smaller. Each will be longer.

However, since members such as bars are provided vertically and horizontally on the back side of the mounting surface such as the back of the wall, the embedded box is required to have a small depth and a small difference in vertical and horizontal dimensions.

[0008]

SUMMARY OF THE INVENTION In view of these circumstances, the present invention provides a flush-type faucet without deteriorating the operability of the open-close handle by devising the positions of the open / close valve and the water discharge port in the flush box. The purpose is to make the embedded box compact.

[0009]

Means for Solving the Problems In order to solve the above problems,
The embedded water faucet of the present invention, in an embedded box with an open front surface, a connection portion of a rising water supply pipe, a water outlet,
A water faucet provided with an opening / closing valve for opening and closing the flow passage is provided in the middle of the flow passage connecting the water supply pipe connection portion and the water discharge opening, and the water discharge opening and the opening and closing are opened by a cover covering the opening. In the embedded faucet having an opening / closing handle of a valve portion protruding, the flow path is formed by a first flow path directed upward, a second flow path extending substantially horizontally from an upper end of the first flow path, and A third flow path extending downward from the end of the second flow path, wherein the inlet side of the first flow path serves as the connection part, and the water discharge port is connected to the outlet side of the third flow path, The on-off valve is provided at a communication portion between the first flow path and the second flow path.

[0010] With this configuration, the water discharge port and the opening / closing valve are located on the diagonal line of the embedding box, the vertical and horizontal dimensional differences of the embedding box are reduced, and the depth thereof is reduced. The space with the water outlet can be secured, and the operability is good.

A lever portion is provided on the opening / closing handle so that the opening / closing angle range of the opening / closing valve is substantially 90 degrees. When the lever portion is oriented in the horizontal direction, the opening / closing valve is closed.
When the lever portion is directed downward, it is preferable that the on-off valve be opened. In this case, not only is the opening / closing operation easy, but also, for example, it is connected to a fully automatic washing machine. Intuitively, even when the solenoid valve is closed and water is stopped, if the direction of the lever part is the same as the direction of the water discharge port part, it is intuitive that the on-off valve part is left open. Can be recognized.
