Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an embedded faucet in which a faucet body is embedded in an installation site such as a counter or a wall surface.

[0002]

2. Description of the Related Art In a so-called embedded water faucet, a water faucet unit containing a water faucet or the like may be installed on the primary side thereof. For example, as in the conventional example 1 shown in FIG. 6, the faucet body 20 embedded in the installation site 10 and the water shutoff unit 50 installed at the terminal portion of the original pipe 91 are connected via the connecting pipe 92. Connection (see Japanese Patent Laid-Open No. 10-1988, etc.) is performed.

[0003]

However, this conventional example 1
In the above, since the faucet main body 20 and the water stopcock unit 50 are arranged in a state of being separated from each other and it is necessary to install both separately, it is troublesome in construction. For example, the water stopper unit 50 is attached to the mounting surface 1 in the installation site 10 by using a stay 45 or the like.
8 and the work for connecting and fixing to the terminal portion of the original pipe 91 that is 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 carry out the work to be performed and the work to be performed at separate locations. Moreover, the work of connecting the water stopper unit 50 and the connecting pipe 92, and the faucet body 20 and the connecting pipe 9
This is because it is necessary to separately perform the work of connecting the two and the work ports and the like provided at the positions separated from each other.

Further, it is necessary to provide a work port 95 for connecting the water stop unit 50 and the connecting pipe 92 to the panel 94 or the like constituting the outer shell of the installation site 10. Therefore, not only the structure of the panel 94 and the like becomes complicated, but also the work port 95 and the lid (not shown) for opening and closing the port may impair the appearance of the installation site 10.

Further, when performing maintenance on the embedded faucet 12, it may be necessary to remove the faucet body 20 from the installation site 10. In this case, first, the faucet body 20 is removed. It is necessary to cut off the supply of hot water. However, when the faucet body 20 and the faucet unit 50 are separated from each other as in the conventional example 1, the water stop operation is performed on the water stopcock unit 50 by going back to the primary side of the faucet body 20.
Then, return to the installation location of the faucet body 20
Need to be removed. Therefore, it is difficult to efficiently perform maintenance on the faucet body 20 and the like.

Further, as in the prior art example 1, the faucet body 2
When 0 and the water stopper unit 50 are connected by the connecting pipe 92, a large amount of residual water exists in the connecting pipe 92 when the water stopper unit 50 is stopped.
Therefore, when the faucet body 10 is removed, this large amount of residual water may spill out into the inside of the installation site 10 and cause a problem such as contaminating the inside. 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 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 expelled 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 portion 10 is provided with a water stopper unit 50 and a water stopper body 20. A built-in faucet 12 with an integrated product is also proposed (Shokai Sho 5
5-94974). In this conventional example 2, since the water stop unit 50 and the faucet body 20 of the illustrated example are directly screw-connected, a connecting pipe 92 or the like as shown in the above-mentioned conventional example 1 is interposed therebetween. You don't have to.

However, in the conventional example 2, the water faucet unit 50 is not only fixedly installed in the mounting hole 93, but also a sufficient empty space is not secured in the mounting hole 93. It is virtually impossible to provide relative rotation between the main body 20 and the water stop unit 50 arranged on both sides of the main body 20. That is, with the water stopper unit 50 still installed in the mounting hole 93, the screw connection between the water stopper unit 50 and the water stopper body 20 is released, and the water stopper body 20 is released.
It is difficult to attach and detach the chisel alone. Therefore, it is necessary to attach / detach the water faucet body 20 integrally with the water faucet unit 50.
It is necessary to install another water stopcock on the next side and perform a water stop operation on this other water stopcock. Therefore, the above-mentioned conventional example 1
Similarly, when the faucet body 20 or the like is attached or detached, it is necessary to go back to the primary side of the faucet body 20 and perform a water-stop operation on the other water stopcock. On the other hand, it becomes difficult to perform efficient maintenance.

In the conventional example 2, it is necessary to break the mounting hole 93 in order to take out the stopcock unit 50 and the faucet body 20 of the illustrated example as a unit. Therefore, in the second conventional example, an opening 96 is provided on the front surface of the faucet body 20, and a lid 97 is provided in the opening 96.
Is detachably attached. Then, by attaching and detaching this lid body 97, the faucet body 20 and the water stop unit 5
With 0 held in the mounting hole 93,
In particular, the device 98, which is frequently maintained, can be attached and detached. However, according to this aspect, the embedded faucet 1
In some cases, the structure of No. 2 becomes complicated, resulting in high manufacturing cost. Further, since the faucet body 20 is held in the mounting hole 93 and does not reach the operator's hand, 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 present invention is to provide an embedded faucet capable of efficiently performing construction and maintenance. To do.

[0011]

In order to solve the above-mentioned problems, first, the means adopted by the invention of claim 1 is "an embedded faucet in which a faucet body is embedded in an installation site such as a counter or a wall surface. In addition, the connection part of the water stopper unit equipped with the water stopper is removably directly attached and fixed to the connected portion of the water stopper body.
And a buried faucet, provided abutment flange to the connection part, to該衝Gotsuba
An abutting collar that abuts is provided on the connected part, and an abutting collar
The connecting clip by locking the fastening clip between the
It is an embedded faucet characterized by being fixed to the connection part . "

According to the first aspect of the present invention, it is not necessary to separately use the fixing means for fixing the water stop unit and the fixing means for fixing the water faucet body. That is, if the water faucet body is fixed using a predetermined fixing means, the water faucet unit is fixed using the water faucet body as an interposition, and conversely, if the water faucet unit is fixed using a predetermined fixing means. The water faucet body is fixed with the water faucet unit interposed. Moreover,
Since the water faucet unit is directly attached to the water faucet body and there is no need to interpose a connecting pipe or the like between them, the workability as an embedded water faucet is enhanced. In addition, since the faucet body and the water stop unit can be fixed in the immediate vicinity of the location where the faucet body is placed, the number of work ports, etc. provided at the installation site can be reduced, and the structure of the installation site can be simplified. It is possible to improve the appearance and appearance.

Further, in the embedded water faucet of the present invention, the water faucet unit is arranged in the immediate vicinity of the water faucet body, and moreover, the water faucet unit is detachable, so that efficient maintenance can be performed. You can For example, when the water stop operation is performed on the water stop 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 stop faucet unit can be separated. In other words, it is not necessary to perform the water shutoff operation for the water shutoff unit and the work of separating the water tap body and the water shutoff unit at a plurality of locations separated from each other, so that it is efficient for the embedded water tap. Maintenance can be performed.

Further, according to the present invention, since the water faucet unit is directly attached and fixed to the water faucet body, the flow path existing between the water faucet incorporated in the water faucet unit and the water faucet body. The part can be shortened. Therefore, when the water faucet unit and the water faucet body are separated, the amount of residual water existing on the secondary side of the water faucet can be reduced, so that a large amount of residual water spills into the installation site. It is possible to accurately prevent defects.

Further, since the flow path portion existing between the water stopcock and the faucet body is shortened in this manner, the possibility that foreign matter will enter the faucet body is reduced. That is, in the above-described conventional example 1 or the like, generally, a long connecting pipe 92 is arranged on the secondary side of the water stopcock unit 50 and is present between the water stopcock and the water tap body 20. The flow path becomes longer. Moreover, with the contractor of the original pipe 91 and the water stopcock unit 50,
In general, the contractor of the embedded faucet 12 is a separate company, and the embedded faucet 12 may be constructed after a certain period of time has elapsed after the construction of the main pipe 91 and the like. is there. In such a case, there is a high possibility that foreign matter or the like in the atmosphere of the construction site will infiltrate and accumulate in this flow path portion. On the other hand, according to the present invention, as described above, since the flow path portion existing between the water stopcock and the water tap body is shortened, such a problem is less likely to occur. Moreover, even if a foreign matter enters this short flow path portion, the accumulated amount of this foreign matter is small and it is easy to remove it. Therefore, according to the present invention, it is possible to properly prevent foreign matter from entering the faucet body, and ensure good performance of various devices such as a valve device built in the faucet body.

Here, as the "installation site" of the present invention,
For example, a counter provided in a bathroom, a washroom, a kitchen, a deck surface, a wall surface, or the like can be exemplified. Further, the "stop cock unit" of the present invention includes, in addition to the one having only the stop cock, one having at least one other maintenance device such as a strainer and a check valve together with the stop cock. included. Further, various fixing means for fixing the faucet body or the water stop unit to the installation site can be selected. For example, (1) the outer body itself that constitutes the installation site, such as a panel,
Alternatively, a mode in which the faucet body or the water stop unit is indirectly fixed to a mounting surface such as a back wall surface provided in the installation site via a fixture such as a stay, (2) the outer shell itself,
Or a mode in which the faucet body or the water stop unit is directly fixed to the mounting surface or the like by a method such as screwing, (3)
Examples include a mode in which the outer shell is clamped and fixed by a fixing collar portion provided on the water faucet body or the water stop unit and a separate fixing nut.

At the time of this assembling, the male screw portion of the outer peripheral surface of the water stop cap 53 is screwed into the female screw portion of the inner wall surface of the attachment / detachment port 61.

Further, in each of the present inventions, unlike the present embodiment, the strainer 55 may be provided on the faucet body 20 side.
Further, in this example, the water stopcock unit 50 that incorporates the strainer 55 together with the water stopcock 52 is illustrated, but the waterstop cock unit 50 of each of the present invention may include only the water stopcock 52,
The check valve 28 may be built in together with the water stopcock 52 and the strainer 55. In particular, the water faucet unit 50
In addition, multiple functional devices are aggregated, and the functional devices are connected to the faucet body 20.
If it is not necessary to incorporate it into the housing, the structure of the faucet body 20 can be simplified and downsized.

In this example, the water faucet unit 50 is installed in the counter 10 in advance, and for example, a work port constituted by removing the top panel 15 from the counter 10, that is, the faucet body 20 is installed. It is directly attached and fixed to the faucet body 20 by using a work port for inserting and fixing it in the counter 10. Specifically, a tool such as a spanner is inserted into the counter 10 through this working port, the female screw portion 79 of the fastening nut 70 is screwed into the male screw portion 54 of the connected portion 27, and the faucet body 20 is attached.

At this time, since the strainer 55 can be attached / detached while the water stopcock 52 with the flow path closed is left in the main body 51, the strainer 55 can be efficiently maintained and replaced.

In this example, the fastening nut 7 is used as a fastener for fixing the connecting portion 57 and the connected portion 27 more smoothly.
Although 0 is illustrated, fasteners of other modes can be used. For example, as a specific example of the invention of claim 1 , a mode using a fastening clip 80 as shown in FIG. 5 can be exemplified. In this aspect, the connecting portion 57 is provided with the abutting flange 81 and the inserting portion 82, the seal member 83 is mounted on the outer peripheral surface of the inserting portion 82, and the connected portion 27 is abutted with the abutting flange. 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 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 has an engaging portion 86 in which upper and lower substantially semicircular plate portions are connected by a substantially U-shaped plate portion. Stop 86
And a pair of upper and lower folded-back portions 87 projecting in a V shape from a pair of upper and lower ends thereof, and a locking groove 88 is formed in an intermediate portion in the width direction. The fastening clip 80 is expanded so that a 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 abutting flange 81 and the abutting flange 84, and the abutting flange 81 and the abutting flange 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 mode, the protective clip 89 is used to prevent the fastening clip 80 from accidentally coming off. The protector 89 is configured by using an elastic body having a substantially U-shaped cross section, and a fastening clip 80 from the side of the pair of upper and lower arm portions 90.
Is to be fitted in a resilient manner. And this protector 8
The function of 9 prevents the fastening clip 80 from falling off even if a tool or the like accidentally contacts the fastening clip 80. Further, in this aspect, the connecting portion 57 is a male type and the connected portion 27 is a female type, but these male and female can be reversed. Further, in the invention of claim 1 , the use of the protector 89 can be omitted.
