DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded faucet in which a faucet main body is embedded in an installation site such as a counter or a wall.

[0002]

2. Description of the Related Art In a so-called embedded faucet, a faucet unit having a built-in faucet or the like may be installed on the primary side. For example, as in Conventional Example 1 shown in FIG. 6, the faucet main body 20 embedded in the installation site 10 and the water stopcock unit 50 installed at the end of the main pipe 91 are connected via the connecting pipe 92. For example, connection (see Japanese Patent Application Laid-Open No. 10-1988) is performed.

[0003]

However, this conventional example 1
In this case, the faucet main body 20 and the water stopcock unit 50 are arranged in a state where they are separated from each other, and it is necessary to install both separately, which is troublesome in construction. For example, the stopcock unit 50 is attached to the mounting surface 1 in the installation site 10 using a stay 45 or the like.
8 and work for connecting and fixing to the end of the original pipe 91 raised from the floor of the installation site 10 and fixing the faucet body 20 in the installation site 10 using a separate stay or the like. It is necessary to perform each of the operations at a separate place separated from the operation. Moreover, the operation of connecting the water stopcock unit 50 and the connection pipe 92, the operation of the water tap body 20 and the connection pipe 9
This is because it is necessary to separately perform the work of connecting the two through a work port or the like provided at a position separated from the work.

In addition, it is necessary to provide a working port 95 for connecting the water stoppage unit 50 and the connecting pipe 92 to the panel 94 or the like constituting the outer periphery of the installation site 10. Therefore, not only the structure of the panel 94 and the like becomes complicated, but also the appearance of the installation site 10 may be impaired by the work opening 95 and a lid (not shown) for opening and closing the work opening 95.

Further, when performing maintenance on the embedded faucet 12, it may be necessary to remove the faucet main body 20 from the installation site 10, but in this case, first, the faucet main body 20 must be removed. It is necessary to cut off hot water supply. However, when the faucet main body 20 and the faucet unit 50 are separated from each other as in Conventional Example 1, the water stop operation is performed on the faucet unit 50 by going back to the primary side of the faucet body 20.
Next, returning to the installation location of the faucet body 20, the faucet body 20
Must be removed. Therefore, it is difficult to perform efficient maintenance on the faucet body 20 and the like.

Further, as in the prior art 1, the faucet body 2
When the water stopcock unit 50 is connected to the water stopcock unit 50 by the connection pipe 92, a large amount of residual water exists in the connection pipe 92 when the water stoppage operation is performed on the water stopcock unit 50.
Accordingly, a large amount of residual water may spill out into the installation site 10 on the beat from which the faucet main body 10 is removed, which may cause problems such as contamination of the interior. In particular, when the connecting pipe 92 is configured by using a flexible pipe, the time when the connection between the connecting pipe 92 and the faucet main body 10 is released,
There is a possibility that the connecting pipe 92 hangs down inside the installation site 10 and this residual water is discharged vigorously.

On the other hand, as in the conventional example 2 of FIG. 7, a substantially box-shaped mounting hole 93 provided on the wall surface showing another specific example of the installation site 10 is provided with the water stopcock unit 50 and the water faucet main body 20. An embedded faucet 12 with an integrated product has also been proposed.
No. 5-94974). In the second conventional example, since the stopcock unit 50 and the faucet main body 20 in the illustrated example are directly screwed and connected, a connecting pipe 92 or the like as shown in the first conventional example is interposed between the two. You don't have to.

However, in the prior art 2, since the water stopcock unit 50 is not only fixedly installed in the mounting hole 93 but also a sufficient free space is not secured in the mounting hole 93, the faucet is not provided. It is virtually impossible to provide relative rotation between the main body 20 and the water stopcock unit 50 arranged on both sides thereof. That is, with the water stopcock unit 50 still installed in the mounting hole 93, the screw engagement between the water stopcock unit 50 and the water faucet body 20 is released, and the water faucet body 20 is released.
It is difficult to attach and detach only one. For this reason, it is necessary to attach / detach the faucet body 20 integrally with the water stopcock unit 50, and after all, one of the water stopcock units 50 in the illustrated example is required.
It is necessary to install another water stopcock on the next side, and to perform the water stoppage operation on this other water stopcock. Therefore, the above conventional example 1
Similarly to the above, when attaching and detaching the faucet body 20 and the like, it is necessary to go back to the primary side of the faucet body 20 and perform a water stoppage operation on this other stopcock. On the other hand, it is difficult to perform efficient maintenance.

In the conventional example 2, in order to take out the water stopcock unit 50 and the water faucet main body 20 in the illustrated example integrally, it is necessary to break the mounting hole 93 once. For this reason, in the conventional example 2, an opening 96 is provided on the front surface of the faucet main body 20, and the lid 97 is
Is detachably attached. By attaching and detaching the lid 97, the faucet main body 20 and the faucet unit 5
0 is held in the mounting hole 93, and
In particular, the equipment 98 that requires frequent maintenance is detachable. However, according to this embodiment, the embedded faucet 1
2 may be complicated, resulting in high manufacturing costs. Further, since the faucet body 20 is held in the mounting hole 93 and does not reach the operator, the faucet body 2
Precise maintenance cannot be applied to every corner of zero.

The present invention has been made in view of such circumstances, and an object of the invention is to provide an embedded faucet capable of efficiently performing construction and maintenance. I do.

[0011]

Means for Solving the Problems In order to solve the above-mentioned problems, first, a means adopted by the invention of claim 1 is that an embedding faucet in which a faucet main body is embedded in an installation site such as a counter or a wall surface. Wherein the connection portion of the water stopcock unit having the water stopcock is detachably and directly attached to and fixed to the connected portion of the water faucet main body.

According to the first aspect of the present invention, it is not necessary to separately use fixing means for fixing the water stopcock unit and fixing means for fixing the water faucet body. That is, if the faucet body is fixed using predetermined fixing means, the water stopcock unit is fixed with the water faucet body as an intervening object, and conversely, if the water stopcock unit is fixed using predetermined fixing means. The faucet body is fixed with the faucet unit as an intervening object. Moreover,
Since the water stopcock unit is directly attached to the water faucet main body and there is no need to interpose a connecting pipe or the like between them, workability as an embedded water faucet is improved. Further, since the faucet body and the water stopcock unit can be fixed very near the place where the faucet body is disposed, the number of working ports provided at the installation site can be reduced, and the structure of the installation site can be simplified. And the appearance can be improved.

[0013] In the embedding faucet of the present invention, since the stopcock unit is disposed very near the faucet body and the stopcock unit is detachable, efficient maintenance can be performed. Can be. For example, if a water stop operation is performed on the water stopcock unit fixed to the water faucet body, the supply of hot water to the water faucet body can be cut off, and the water faucet body and the water stopcock unit can be separated. In other words, it is not necessary to perform the water stoppage operation on the water stopcock unit and the work of separating the water stopcock body and the water stopcock unit at a plurality of locations separated from each other, so that the efficiency of the embedded water stopcock is reduced. Maintenance can be performed.

Further, in the present invention, since the water stopcock unit is directly attached to and fixed to the water faucet main body, the flow passage existing between the water stopcock incorporated in the water stopcock unit and the water faucet main body is provided. Parts can be shortened. Therefore, when the water stopcock unit and the water faucet main body are separated, the amount of residual water present on the secondary side of the water stopcock can be reduced, so that a large amount of residual water spills out into the installation site. Failures can be accurately prevented.

Further, since the flow path portion between the water stopcock and the water faucet main body is shortened as described above, the possibility of foreign matter entering the water faucet main body is reduced. That is, in the above-described embodiment of Conventional Example 1, a long connecting pipe 92 is generally arranged on the secondary side of the water stopcock unit 50, and is present between the water stopcock and the water tap main body 20. The channel portion becomes longer. Moreover, with the contractor of the original piping 91 and the stopcock unit 50,
It is general that the construction company of the embedding faucet 12 is a different company, and after the construction of the original pipe 91 and the like, the embedding faucet 12 is constructed after a certain period of time. is there. In such a case, there is a high possibility that foreign matter and the like in the atmosphere of the construction site will enter the flow path portion and accumulate. On the other hand, according to the present invention, as described above, the flow path portion between the water stopcock and the water faucet main body is shortened, so that such a problem hardly occurs. Moreover, even if foreign matter enters the short flow path portion, the amount of foreign matter accumulated is small, and it is easy to remove the foreign matter. Therefore, according to the present invention, it is possible to accurately prevent foreign matter from entering the faucet body, and to ensure good performance of various devices such as a valve device incorporated in the faucet body.

0 and the stopcock unit 50 can be separated. further,
If the fixing between the stay 40 and the faucet main body 20 or the fixing between the stay 40 and the mounting surface 18 is released, the faucet main body 20 can be taken out of the counter 10. For this, efficient maintenance can be performed. When the pipe 19 is formed of a flexible tube or the like having a sufficient length in the longitudinal direction, the integrated body of the faucet body 20 and the faucet unit 50 is taken out of the counter 10 and then closed to the faucet 52. Valve operation and separation work of the faucet main body 20 and the faucet unit 50 can also be performed.

In the present embodiment, when maintenance or replacement of the strainer 55 is performed, a valve closing operation is performed on the water stopcock 52, and then the water stopcock cap 52 integrated with the strainer 55 is attached and detached. At this time, since the strainer 55 can be attached and detached while the water stopcock 52 with the flow path closed in the main body 51, the maintenance and replacement of the strainer 55 can be performed efficiently.

In this example, the fastening nut 7 is used as a fastener for more smoothly fixing the connecting portion 57 and the connected portion 27.
Although 0 is illustrated, other types of fasteners may be used. For example, as a specific example of the third aspect of the present invention, a mode using a fastening clip 80 as shown in FIG. 5 can be exemplified. In this embodiment, the connecting portion 57 is provided with an abutment flange 81 and an insertion portion 82, and a seal member 83 is mounted on the outer peripheral surface of the insertion portion 82, and the abutment flange 81 is attached to the connected portion 27. 84 and an annular groove 85 are provided. Then, the insertion portion 82 is fitted into the connected portion 27, the fastening clip 80 is locked between the abutting flange 81 and the abutting flange 84 that abut against each other, and the connecting portion 57 is fixed to the connected portion 27. ing.

That is, the fastening clip 80 is formed by bending a leaf spring, and is engaged with a locking portion 86 in which upper and lower substantially semicircular plate-like portions are connected by a substantially U-shaped plate-like portion. Stop 86
And a pair of upper and lower folded portions 87 protruding from the pair of upper and lower end portions in a U-shape, and a locking groove 88 is formed in a widthwise intermediate portion. The fastening clip 80 is expanded so that the pair of upper and lower folded portions 87 are separated from each other, and is locked between the abutting flange 81 and the abutted flange 84 that abut each other. Specifically, the fastening clip 80 is fitted so as to straddle the abutment flange 81 and the abutted collar 84, and the abutment flange 81 and the abutted collar 84 are fitted and locked in the locking groove 88. By doing so, the connecting portion 57 is fixed to the connected portion 27.

In this embodiment, the protective clip 89 is used to prevent the fastening clip 80 from accidentally falling off. The protector 89 is formed using an elastic body having a substantially U-shaped cross section.
Is resiliently fitted to the outside. And this protective equipment 8
By the function of 9, even if a tool or the like accidentally contacts the fastening clip 80, the fastening clip 80 is prevented from falling off. Further, in this embodiment, an example is shown in which the connecting portion 57 is of a male type and the connected portion 27 is of a female type. However, these male and female can be reversed. Further, in the third aspect of the present invention, the use of the protector 89 can be omitted.

According to the first, fourth and fifth aspects of the present invention, the connecting portion 57 and the connected portion 27 can be fixed without using the fastening nut 70 or the fastening clip 80. For example, the abutment flange 81 and the abutment collar 84 shown in FIG. 5 are fixed with screws, or one of the male threads of the connecting portion 57 or the connected portion 27 is directly screwed to the other female thread. They can be fixed together.
