Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an embedded faucet,
In detail, a spout, a spout main body for a spout which has a built-in spout valve device for controlling the spout from the spout, and can be embedded in an installation section such as a bathroom counter, and is routed inside the installation section. And a pipe for connecting the water outlet and the water faucet main body, and the water faucet is rotatably connected to the pipe.

[0002]

2. Description of the Related Art Conventionally, there is a so-called "embedded faucet" in which a faucet body containing a valve device is embedded in an installation portion such as a counter provided in front of a wall surface of a bathroom or the like. In some cases, a spout for spouting water is rotatable. In such an embedded faucet, the faucet body may be rotatably supported by the faucet body. However, in this case, the location of the faucet is limited. Therefore, in order to increase the degree of freedom of the location of the water outlet, the water outlet is connected to the faucet main body via a pipe, so that the water faucet can be disposed separately from the faucet main body. In the embedding faucet described above, a support tool is generally fixed to an installation portion such as a counter, and a water outlet is rotatably supported by the support tool.

[0003]

However, the conventional embedding faucet has the following problems. In the rotatable water spout, a large load is applied to the supporting portion because the water spout is rotated by the user. In particular, when the water outlet is long, even if a slight load is applied to the distal end of the water outlet, a large load is applied to the support portion, which is the base end portion of the water outlet. Therefore, it is necessary to ensure sufficient strength for the installation part for fixing the support. However, improving the strength of the entire installation portion only to secure the strength of the portion supporting the water outlet is cost-effective. In addition, when the installation unit is a counter, even if an attempt is made to provide a water outlet on the lower surface, members such as panel materials constituting the counter may be omitted on the lower surface of the counter. Cannot fix the support, and cannot provide a water outlet.

On the other hand, it is conceivable that the front surface of the counter or the like has sufficient strength, and a water outlet is rotatably provided on the front surface via a support. In this case, the strength of the support must be sufficiently ensured. This is because even if the front surface has sufficient strength, if the support itself is weak, the water outlet cannot be firmly supported. Therefore, in such a case, the support must be integrally and firmly formed of a metal or the like having excellent rigidity, and there is a problem that the degree of freedom in designing the support itself is poor.

The present invention has been made to solve the above-mentioned conventional problems, and has as its object to firmly support a rotatable spout provided independently of a faucet body,
In addition, the water outlet can be provided even in a portion where there is no member constituting the installation part. Further, even when the water outlet is protrudingly provided on the front surface of the installation part, the support used for the water outlet can be provided. That is, the degree of freedom in design can be improved.

[0006]

Means for Solving the Problems Means adopted by each of the present invention to solve the above problems will be described below. The embedding faucet according to claim 1 of the present invention has a built-in water outlet and a water discharge valve device for controlling water discharge from the water discharge port, and is embedded in an installation portion such as a counter in a bathroom.

An embedded faucet, wherein a connecting portion between the pipe and the spout is supported by a spout mounting stay.

[0007] Here, the "stay" is a member made of, for example, a plate or a bar, for supporting and fixing a desired device to a desired portion. Also, "water outlet mounting stay"
Is not limited to those provided independently of the installation part, for example, by a part of a fixing member used to support and fix a member such as a panel material constituting the installation part to a wall surface or the like,
You may make it comprise a water outlet attachment stay.

As described above, by supporting the connection portion of the water outlet by the water outlet mounting stay, the connection portion of the water outlet can be firmly supported regardless of the strength of the installation portion. In addition, even if there is no member that constitutes the installation part at the part where the water outlet is to be provided, the connection part of the water outlet can be supported by the water outlet mounting stay, so that the water outlet can be provided at the part.

[0009] In the present invention, "water faucet main body for spout"
May have at least a built-in water discharge valve device for controlling hot and cold water, and may also include a mixing valve device for mixing hot water and water, and a switching valve device for switching a water discharge passage. It may be built-in.

[0010] The embedding faucet according to claim 2 of the present invention,
The embedded faucet according to claim 1, wherein the faucet main body for the water outlet is supported in the installation part by a water faucet body mounting stay separate from the water outlet mounting stay.

In a mode in which the water faucet main body is supported using a stay, a water outlet mounting stay for supporting a connection portion of the water outlet can be used also. Since the part and the part where the water faucet body for a water outlet is disposed are restricted to each other, the degree of freedom of the part where the water outlet is disposed is reduced. On the other hand, in the present invention, each stay is provided independently by separately providing the water outlet mounting stay supporting the connection portion of the water outlet and the water faucet main body mounting stay supporting the water faucet main body. Accordingly, it is possible to improve the degree of freedom of the arrangement portion of the water outlet.

According to a third aspect of the present invention, there is provided an embedding faucet,
"A mixing valve device for mixing hot water and water is built-in, and a mixing faucet main body is provided separately from the water faucet main body and is embedded in the installation portion. Embedding faucet according to item 2. "

When various valve devices such as a water discharge valve device and a mixing valve device are manually operated, an operation unit for driving these valve devices is operated by a faucet body containing each valve device. It is common to protrude. Therefore, if the mixing valve device is also incorporated in the water faucet body that incorporates the water discharge valve device for the water discharge port, the location of each operation unit for driving each valve device is limited. On the other hand, in the present invention, each faucet is provided by separately providing a faucet body for faucet containing a spout / stop valve device for faucet and a faucet body for mixing containing a mixing valve device. The degree of freedom of the arrangement portion of the main body is increased, thereby increasing the degree of freedom of the arrangement portion of each operation unit for driving each valve device. Therefore, each operation unit can be arranged according to a user's request, and the usability as an embedded faucet is improved.

The embedding faucet according to claim 4 of the present invention comprises:
The embedding faucet according to any one of claims 1 to 3, wherein the water outlet is vertically provided on a lower surface of the installation portion.

When the installation portion is a counter or the like, a certain level of strength is secured on the upper surface and the front surface where various articles may be placed or various articles may collide. However, since the lower surface does not require much strength, it is usually formed fragile, and in some cases, members constituting the lower surface are omitted. In the present invention, since the connection portion of the water outlet is supported by the water outlet mounting stay, the water outlet can be firmly supported even on the lower surface of the installation portion as described above.

According to a fifth aspect of the present invention, there is provided a support structure for a water outlet, wherein the water outlet is protruded from a front surface of an installation portion. Embedded faucet described.

When the water outlet is rotatably provided on the front surface of the installation portion, a support member for rotatably supporting the water outlet is interposed. Therefore, it is necessary to ensure sufficient strength for this support, but in the present invention, since the connection portion of the water outlet is supported by the water outlet mounting stay, the strength for supporting the water outlet is determined by the water outlet mounting stay. Can be secured. Therefore, it is not necessary to form the entire support firmly and integrally with metal or the like, and the main body forming the appearance of the support, the internal flow path, and the like can be formed to some extent fragile. Thereby, various members can be adopted as members constituting the main part of the support, and the degree of freedom in designing the support is improved.
