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, and the faucet body is fixed to a mounting portion provided in the installation site. .

[0002]

2. Description of the Related Art In a so-called embedded faucet, generally, as shown in FIGS. 7 (a) and 7 (b), a stay 40 is attached to a rear wall-shaped mounting portion 18 provided in a counter 10. The front face portion 46 of the stay 40 is sandwiched between the flange portion 91 on the front face side of the water faucet body 20 and the fixing nut 92, and the water faucet body 20 is fixed to the mounting portion 18. (See Japanese Patent Laid-Open No. 10-1988).

[0003]

However, according to this fixing method, since it is necessary to use a large stay 40 extending from the front of the faucet body 20 to the mounting portion 18, the installation space for the embedded faucet 12 is required. Grows larger. Therefore, it may not be suitable for the small counter 10 or the like. In particular, when the embedded faucet 12 has a plurality of functional parts such as a temperature control mechanism and a water blocking mechanism, the faucet body 20 becomes large, and it becomes necessary to use a larger stay 40.
Since the installation space of the embedded faucet 12 becomes larger, the application becomes more difficult.

It should be noted that it is conceivable to enlarge the installation site 10 in order to suitably apply the fixing method shown in the figure, but this enlargement is not always easy. For example, in the bathroom counter 10 in the illustrated example, if the front-rear width (D) of the internal space is increased, the amount of the counter 10 exposed to the inside of the bathroom is increased and the empty space of the bathroom is narrowed. Further, in this type of counter 10, a shampoo, a wash implement, etc. are generally placed on the upper surface thereof, but if the vertical width of the internal space is increased, the total height of the counter 10 becomes excessive. Therefore, it is difficult for the user sitting in the washroom to access the shampoo and the like, and the counter 10 has poor usability. Further, the total height of the counter 10 becomes excessively large, so that the empty space in the bathroom becomes narrow. In particular, in a counter 10 originally provided in a small room such as a bus unit of a one-room apartment, it is difficult to secure a sufficient front and rear width and a vertical width of the internal space.

Further, as shown in the figure, the faucet body 20 is provided with various connection ports 27, 27, 36, and various pipes for hot water supply 19, water supply pipe 19, shower pipe 37, etc. It is general that the piping of is connected. Therefore, the work of attaching and detaching the stay 40 to and from the mounting portion 18 is performed by the various pipes 19, 19, 37 routed around the faucet body 20.
Since it is necessary to avoid the above, the workability of construction and maintenance of the embedded faucet 12 is deteriorated. Alternatively, in some cases, in order to secure workability of construction and maintenance, there is no choice but to limit the manner of routing the pipes 19, 19, 37.

Incidentally, the above-mentioned Japanese Patent Laid-Open No. 10-1988 discloses a specific example in which the side surface portion 48 of the stay 40 is constituted by a frame body separate from the front surface portion 46. In this example,
Since each of the pipes 19, 19, 37 can pass through the frame of the side surface portion 48, the degree of freedom in routing the pipes 19, 19, 37 is improved. However, according to this specific example, the structure of the stay 40 is complicated and the number of parts is increased, so that not only the time and effort for attaching and detaching the stay 40 increase but also the side portion 48 is configured by a frame body. Therefore, the strength of the stay 40 may be reduced.

On the other hand, if the faucet body 20 is directly fixed to the outer shell forming the installation site 10, it is not necessary to use the stay 40, and the above-mentioned problems can be eliminated. For example, in the embodiment shown in the drawings, if the front panel 16 is sandwiched between the flange portion 91 of the faucet body 20 and the fixing nut 92, the stay 40 need not be used. However, in order to use this aspect, it is necessary that the outer shell has sufficient strength. For example, it cannot be suitably applied to the front panel 16 or the like having a low strength formed by using a thin resin panel or the like. Therefore, this aspect cannot be generally applied to the installation site 10 formed by the outer shell having various materials and strengths. still,
It is also possible to separately provide the faucet body 20 with a structure for fixing the faucet body directly to the mounting portion 18 or with the stay 40 interposed. However, in this case, a separate structure has to be provided for the faucet body 20 only for fixing, which lowers the degree of freedom in designing the faucet body 20 and raises the cost.

The respective inventions of the present invention have been made in view of such circumstances, and an object of the invention is that they can be suitably installed regardless of the size of the installation site, the strength of the installation site, and the like. It is an object of the present invention to provide an embedded water faucet capable of increasing the degree of freedom of wiring.

[0009]

In order to solve the above problems, first, the means adopted by the invention of claim 1 is that "the faucet body is embedded in an installation site such as a counter or a wall surface and the faucet is installed. a buried faucet to be fixed to the mounting portion main body is provided in the installation site, filled with respect to the faucet body mounting portion that is fixed with a rib provided in the water plug body
It is a faucet, and the rib reinforces the protruding part of the faucet body
It is an embedded water faucet characterized by

According to the first aspect of the present invention, the faucet body is fixed by directly fixing the rib to the mounting portion or fixing the rib to the mounting portion via the stay. Here, according to the former mode of directly fixing the ribs, since the stay is not arranged around the faucet body, not only the installation space for the embedded faucet can be reduced but also the periphery of the faucet body can be largely opened. Also, in the latter case where the stay is used, it is sufficient to use a stay that can intervene between the rib and the mounting portion, and it is not necessary to use the large-sized stay 40 as shown in FIG. The installation space of the faucet can be reduced and the perimeter of the faucet body can be opened widely.

Therefore, the installation space of the embedded water faucet can be reduced by either of the former and the latter modes, so that the embedded water faucet is suitable for installation sites having various sizes and various sizes. Can be installed. Further, since the periphery of the faucet body can be largely opened, the degree of freedom of "piping around" around the faucet body is improved. Further, in this way, since the periphery of the faucet body can be largely opened, each pipe is less likely to interfere with the attachment / detachment work when the faucet body is attached / detached, and the workability of the embedded faucet construction and maintenance is improved. improves. In addition, even if the outer shell that constitutes the installation site does not have sufficient strength, for example, the back wall in the installation site can be preferably used as the attachment part, so that the strength of the installation site does not matter. It can be suitably installed without using it.

Here, the term "rib" refers to a portion integrally extended from the faucet body to reinforce the faucet body.
Further, as the "installation site", for example, a bathroom, a washroom,
Examples include a counter, a table surface (deck surface), a wall surface, etc. provided in a kitchen or the like. Furthermore, as the "mounting part", "a back wall provided inside the counter or behind the wall surface,"
In addition to the one provided at the rear end portion inside the installation site such as "a bottom wall provided below the table surface", the inner wall of the outer shell forming the installation site and the like can be exemplified. The rib reinforces the faucet body and is naturally required for the faucet body. Therefore, the ribs do not reduce the degree of freedom in designing the faucet body. In the present invention, the number of ribs provided on the faucet body is not particularly limited as long as it is one or more. Further, when the faucet body is provided with a plurality of ribs, it is not necessary that all of them are ribs involved in fixing the faucet body, that is, fixing ribs. When a plurality of ribs are provided, a suitable rib may be selected and used as a fixing rib depending on the installation space and the layout of the pipe.

Next, the means adopted by the invention of claim 2 is as follows.
“The embedded faucet according to claim 1, wherein the rib is provided at a portion of the faucet body facing the mounting portion”.

The invention of claim 1 also includes a mode in which the rib is provided at a portion not facing the mounting portion. For example, when the back wall is used as the mounting portion, a mode in which ribs are provided on the surface of the faucet body that does not face the back wall, that is, the front surface, the top surface, the bottom surface, or both side surfaces of the faucet body is also included. However, in this aspect, it is necessary to form the rib in a slightly elongated shape so that the end of the rib reaches the back wall, or to use a stay in a slightly elongated shape from the non-facing surface to the back wall. Becomes Therefore, there is a possibility that the degree of openness around the faucet body may be reduced due to the passage of the slightly elongated ribs, stays, or the like around the faucet body. In addition, it is necessary to make the slightly long rib thicker and secure its rigidity, which may lead to higher manufacturing cost of the embedded faucet.

On the other hand, according to the second aspect of the present invention, since the rib is provided at a portion facing the mounting portion, it is possible to further reduce the size of the rib and the stay and further simplify the structure. . Therefore, not only the degree of openness around the faucet body is further improved, the degree of freedom in routing the pipes is further increased, but also the installation space for the embedded faucet is further increased.
Get smaller. For example, when the back wall is used as the attachment portion, the faucet body has a front surface, a top surface, a bottom surface, or a side surface that is substantially completely opened, and the pipe can be freely routed around these surfaces. . Further, the manufacturing cost and the construction cost of the embedded faucet can be reduced by further downsizing the ribs and stays and further simplifying the structure.

The means adopted by the invention of claim 3 is as follows.
"The embedded faucet according to claim 1 or 2, wherein the rib is fixed to the attachment portion via a stay."

The inventions of claims 1 and 2 include a mode in which the rib is directly fixed to the mounting portion as described above. However, according to this aspect, for example, it is necessary to provide a flange for fixing to the mounting portion at the end portion of the rib,
It is necessary to provide a special fixing structure for the rib, which must be formed integrally with the faucet body as part of the rib. Therefore, it may be difficult to form the faucet body by the amount of the fixing structure. On the other hand, according to the third aspect of the invention, since it is sufficient to provide the stay with the fixing structure to the mounting portion, it is not necessary to provide the rib with a special fixing structure. Therefore, it does not hinder the formation of the faucet body.

Next, the means adopted by the invention of claim 1 is as follows.
"The ribs, to that buried faucet, characterized in that to reinforce the projecting portion of the faucet body" is.

In the faucet body, for example, a connection port for connecting a hot water supply pipe, a connection port for connecting a water supply pipe, a connection port for connecting a shower pipe, etc. are provided as protruding portions. May be provided. Where the rib is
It is often provided to reinforce the protruding portion. In the invention of claim 1 , it is intended that the rib for reinforcing the protruding portion is also used as the “rib” shown in the invention of claims 1 to 3, that is, the “fixing rib”. It also shows a specific mode. The reinforcing rib is not limited to the one that reinforces the protruding portion as described above, but may be extended from the faucet body to reinforce the thin portion, for example .

Next, the means adopted by the invention of claim 4 is as follows.
The "embedded water faucet according to any one of claims 1 to 3, wherein two predetermined protruding portions are reinforced by a single rib."

According to the fourth aspect of the present invention, since the rib is stretched over the two projecting portions, each projecting portion, and further, the faucet body is reinforced more reliably. Further, since the strength of the rib itself is improved, the faucet body can be fixed more reliably. Further, in the mode using the stay, the rib is stretched over the two projecting portions and has a sufficient width, so that the rib and the stay are fixed more smoothly.

[0022]

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the "buried faucet" according to the present invention will be described in detail with reference to the drawings.

In this example, as shown in FIG. 1, an embedded faucet 12 installed in a bathroom counter 10 showing an example of "installation site" will be described. Here, the counter 10 of the present example is provided with an embedded faucet 11 for a bathtub and an embedded faucet 12 for a washing place, and the embedded faucet 12 for a washing place is one specific example of the present invention. Is shown. However, the present invention can also be applied to the embedded faucet 11 for the bathtub.

Further, as the embedded faucet 12 for the washing place, that is, the embedded faucet 12, the handle 21 for temperature adjustment is used to adjust the water discharge temperature, and the handle 22 for water discharge is used. The hot and cold water mixing faucet is shown as an example, which selects the discharge water, adjusts the discharge amount, and switches the water discharge direction between the currant 23 and the shower head 24. However, the embedded faucet of the present invention is not limited to a hot and cold water mixed faucet, and may be, for example, a single faucet, a water purifier faucet, or another type of faucet such as an alkaline ionized water production device. Good. In addition, in this example, as the embedded faucet 11 for the bathtub, a "single faucet" is shown, in which a single handle 13 is rotated to select the stop water and adjust the water discharge amount.

Next, the detailed structures of the counter 10 and the main water faucet 12 will be described with reference to FIGS. 2 and 3. First, the counter 10 has a top panel 15 that constitutes the upper surface.
And a front panel 16 forming a front surface and a lower surface. In addition, in this counter 10, the amount of protrusion from the back wall-shaped mounting portion 18 is small, and the vertical width is made small so that the lower part of the front panel 16 is an empty space continuous with the inside of the bathroom. And this empty space is, for example,
It is effectively used as an insertion place for a wash basin or the like, or as an operation space for a water stopcock 52 described later. In addition, counter 1
The mode of 0 is not limited to this example, and for example, the top panel 1
5 and a front plate panel that reaches the floor surface of the bathroom from the projecting end thereof, or a swelling portion in a part of the front surface portion may be used.

On the other hand, the embedded faucet 12 is a counter 10
A faucet main body 20 embedded in the front panel 16, a handle 21 for temperature control and a handle 22 for water discharge that respectively project from the front panel 16 into the bathroom, and a curran 23 hanging from the lower surface of the front panel 16. . Of these, the faucet body 2
In No. 0, the hot water supply connection port 27 is projected toward the rear surface of the left side surface, and the water supply connection port 27 is projected toward the rear surface of the right side surface. Further, the temperature adjusting mechanism 25 is built in the front and rear of the left side through the tubular portion 29 protruding to the left side of the front surface, and the front and rear discharge is stopped through the tubular portion 29 protruding to the right side of the front surface. The water mechanism 26 is incorporated. And the temperature control mechanism 2
5 and the respective axis centers of the water discharge and stop mechanism 26 are connected to the hot water supply port 27.
And the respective axial centers of the water supply connection ports 27 are substantially orthogonal to each other.

However, in each of the inventions, the temperature adjusting mechanism 2 is used.
No particular limitation is placed on the arrangement of the water discharge and water stop mechanism 26. For example, the tubular portions 29, 29 are provided on the left and right side surfaces of the faucet body 20, and the temperature control mechanism 25 and the water stop mechanism 26 are coaxial. You may install in parallel. However, in such a mode in which they are arranged side by side coaxially, it is necessary to expose the operation shaft of the temperature adjustment mechanism 25 and the operation shaft of the water stop mechanism 26 to the outside of the counter 10 on the left and right sides. Therefore, it is necessary to provide a bulging portion or the like on the counter 10 and expose each operation shaft to the inside of the bathroom through the left and right side surfaces thereof. On the other hand, in the aspect of the present example, as illustrated in FIG. 2, it is sufficient to expose each operation shaft 34 to the front of the counter 10, and therefore various forms are provided regardless of whether or not the bulge portion is provided. It can be suitably installed on the counter 10 equipped with.

In this example, as the temperature adjusting mechanism 25,
"A wax element, shape memory alloy element, etc.
A thermostat type valve device that automatically adjusts the degree of mixing of hot water and water is used. However, this temperature control mechanism is not limited to this thermostat method, and for example,
(A) A sliding valve system configured by using a fixed valve and a movable valve that slide with each other to open and close a flow path, and (b) two handles that adjust the mixing degree of hot water and water with separate handles. Other schemes such as schemes can also be used. Also,
In this example, a "sliding disk type" valve device is used as the water discharge and water stop mechanism 26, but (c) the valve body is advanced and retracted with respect to a pair of opposed valve openings to open and close the flow path. Lift system, (d) Ball valve system having a valve opening and a ball-shaped valve body biased toward the valve opening, and opening and closing the valve opening by relatively moving the valve body and the valve opening It is also possible to use other methods such as.

Further, in the present embodiment, as the water discharging / stopping mechanism 26, the one for performing the "water discharge controlling" and the "water discharge amount adjustment" and the "switching of the water discharging direction" is used. With only "selection" and this "selection of discharge water",
One of “adjustment of water discharge amount” or “switching of water discharge direction” may be performed. Further, in the embedded faucet of each of the present invention, the faucet body has one of a temperature adjusting mechanism and a water blocking mechanism incorporated therein as a functional part, or a valve device of another aspect, for example, a temperature adjusting mechanism. Alternatively, a device having a built-in sliding disk valve that also has the function of the water discharge and stop mechanism may be used.

Connection port 27 for hot water supply and connection port 2 for water supply
The check valve 28 is built in the device 7. In this example, since the check valve 28 is built in these connection ports 27 as described above, the check valve is provided in a portion of the faucet body 20 other than the both connection ports 27, that is, in a main portion of the faucet body 20. It is not necessary to secure a built-in space for housing 28. Therefore, in this example, although the faucet body 20 has two function parts, that is, the temperature control mechanism 25 and the water discharge prevention mechanism 26,
It has a simple box shape and is relatively compact. Therefore, also from this point, the main faucet body 20 can be suitably installed on the counters 10 of various sizes. It should be noted that the check valve 28 should be built in the connecting portion 57, which will be described later, or built in so as to straddle both the internal spaces of the hot water supply and water supplying connection ports 27, 27 and the internal space of the connecting part 57. You can also

Further, the terminal portion of the hot water supply pipe 19 is connected to the hot water supply connection port 27 through the water stop unit 50, and the water supply connection port 27 is connected to the terminal of the water supply pipe 19. The parts are connected via a water stop unit 50. still,
In this example, as the water stopper unit 50, one having a water stopper 52 and a strainer (not shown) built therein is used.
It may be one that incorporates only the water stopcock 52, or one that incorporates the above-described check valve 28 together with the water stopcock 52. Also,
In the present invention, each connection port 2 for hot water supply and water supply
You may connect the terminal part of each piping 19 directly to 7, 27, and arrange | position a functional apparatus, such as a water stop, in the intermediate part of each piping 19. However, according to the aspect of the present example, it is not necessary to fix the water shutoff unit 50 itself to the mounting portion 18, the top panel 15, the front panel 16, or the like.

Further, the hot water supply connection port 27 has the hot water supply passage 3
0 is connected to the hot water inlet of the temperature control mechanism 25, and the connection port 27 for water supply is connected to the temperature control mechanism 25 through the water supply passage 31.
Is connected to the water entrance. Then, the hot water supplied from the hot water inlet and the water supplied from the hot water inlet have a temperature adjusting mechanism 25.
It is made into hot and cold water of a desired temperature by this temperature control mechanism 2
It flows out to the hot and cold water flow path 33 through the hot and cold water outlet 5. Further, the hot and cold water flowing out to the hot and cold water flow passage 33 is discharged and stopped by the water stop mechanism 2.
6, and the discharge water stop mechanism 26 causes the hot and cold water to flow to the above-described Karan 23 and to the Karan-side outflow passage 35.
To or from the shower head 24 to the side of the shower connection port 36 that communicates with the shower head 24 described above, and the selection of spouting water and adjustment of the spouting amount are performed. The shower connection port 36 is projected toward the front side of the right side surface of the faucet body 20, and is connected to the shower head 24 through a shower pipe 37 that is routed above the faucet body 20. ing.

A branch connection port 38 projects from the top surface of the faucet body 20, and the hot and cold water flow passage 33 is branched to the connection port 38 side to form a branch flow passage. That is, the branch flow path is mainly configured by the branch pipe 39 connected to the branch connection port 38,
The branch pipe 39 is routed above the faucet body 20 and communicates with the above-mentioned embedded faucet 11 for bathtub.
When the handle 13 of the embedded faucet 11 for the bathtub is rotated, hot and cold water having a desired temperature is discharged by the temperature adjusting mechanism 25.

As described above, in this embodiment, the hot water supply and water supply pipes 19 and 19 are arranged on both sides of the faucet body 20, and the pipes are branched to the left side from the upper surface of the faucet body 20. Piping 3
9 is routed, and a shower pipe 37 is routed from the right side surface of the faucet body 20 to the upper side and the left side. That is, the pipes 19, 19, 37, 39 are laid out in a complicated manner around the entire periphery of the faucet body 20 except for the back and the lower part. The reason why such complicated piping can be smoothly carried out is that there are no obstacles such as stays 40 on both side surfaces or the upper surface of the faucet body 20, as will be described later.

As described above, the vertical width of the counter 10 is made small, but in this example, since a sufficient empty space can be secured above the faucet body 20 in the counter 10, it can be used for branching. The pipe 39 and the shower pipe 37 are laid out with a margin. what if,
Unlike this example, each connection port 27, 27 for hot water supply and water supply
When is provided on the bottom surface of the faucet body 20, it is necessary to route the hot water supply and water supply pipes 19 and 19 below the faucet body 20. For this reason, the installation space for the main embedded faucet 12 becomes large in the vertical direction, and it becomes difficult to secure the above-mentioned empty space. On the other hand, as in this example,
Each of the hot water supply and water supply connection ports 27, 27 is provided with a faucet body 20.
This is because the installation space of the main embedded faucet 12 becomes smaller along the up-down direction when it is provided on both side surfaces, so that a sufficient empty space can be secured above the faucet body 20.

In the faucet body 20 described above, as the projecting portion, the hot water supply connection port 27 and the water supply connection port 27 are provided.
, Shower connection port 37, and branch connection port 38
And tubular portions 29, 29. In this example, among these protruding portions, the rib 60 according to the invention of claim 4 is provided between the hot water supply connection port 27 and the water supply connection port 27.
To reinforce the faucet body 20. The rib 60 is provided on the back surface of the faucet body 20 and is attached to the mounting portion 18
The invention of claim 2 is provided. In this example, the rib 60 is attached to the stay 4 according to the invention of claim 3.
It is fixed to the mounting portion 18 via 0.

Next, the structure of the stay 40 will be described with reference to FIG. That is, the stay 40 includes the horizontal plate portion 41,
The horizontal flat plate portion 41 includes a pair of left and right hanging portions 43 that hang down from both ends of the rear end edge, and a vertical portion 45 that extends vertically from the middle of the rear end edge of the horizontal plate portion 41. And this stay 4
0 is used by fixing the horizontal plate portion 41 to the rib 60 with screws and fixing the hanging portion 43 and the hanging portion 45 to the mounting portion 18 with screws. The method of fixing the stay 40 to the ribs 60 and the like is not limited to screw fixing, and, for example, the stay 40
It is also possible to provide a pair of sandwiching portions to sandwich and fix the rib 60, or to fix the stay 40 to the rib 60 by adhesion. When the top panel 15 and the front panel 16 that form the outer shell of the counter 10 have sufficient strength, these inner wall surfaces can be used as the mounting portion 18. Further, the location where the rib 60 is formed can be appropriately changed in consideration of the positional relationship with the mounting portion 18. For example, when the inner wall surface of the front panel 16 is used as the mounting portion 18, both tubular portions 29, 2
It is preferable to form the ribs 60 in a state where the ribs 9 are bridged over each other.

In this example, the faucet body 20 is replaced by the counter 10
When installed inside, (1) the stay 40 may be fixed to the attachment part 18 after fixing the stay 40 to the faucet body 20 in advance, or (2) the stay 40 may be fixed to the attachment part 18 in advance. After that, the faucet body 20 may be fixed to the stay 40. Then, in any of the aspects, the main faucet body 2
For example, 0 is inserted and fixed in the counter 10 through a large work opening configured by temporarily removing the top panel 15 and opening the upper surface of the counter 10. Further, in any of the aspects, the work inside the counter 10 is performed using this large work port, and the various pipes 19 and 1 are used.
It can be efficiently performed behind the faucet main body 20 which is in an open state without 9, 37 and 39.

In this example, a small stay 40 is attached to the rib 60, which is substantially flush with the back surface of the faucet body 20, from the back of the rib 60, and the stay 40 is fixed to the mounting portion 18. Therefore, as shown in FIG. 2, the back surface of the faucet body 20 can be brought into a state of being very close to or substantially in contact with the mounting portion 18, so that the installation space for the embedded faucet 12 can be set. Is smaller. Therefore, even if the counter 10 is small along the front-rear direction, it is preferably installed. Further, in this example, a fixing structure in which the back surface of the faucet body 20 is supported by a small stay 40 is adopted, and both side surfaces, upper and lower surfaces, the front surface, etc. of the faucet body 20 are in an open state. Various pipes around 19, 19, 37, 3
9 has a higher degree of freedom in routing.

In the present example, (3) even if the pipes 19, 19, 37, 39 are connected to the faucet body 20 with respect to the faucet body 20 installed in the counter 10, (4 ) After making this connection outside the counter 10, the faucet body 20 to which the pipe connection is made may be installed inside the counter 10. Here, in the former case (3), a tool such as a spanner is inserted into the counter 10 at the time of construction or maintenance of the embedded faucet 12 to connect the connection port 27 and the connection part 57 of the water stop unit 50. It is necessary to attach / detach the fastening nut 70 interposed between the connection ports 37 and 38 and the pipes 37 and 39. However, the stay 40 does not exist, and the tool can be operated on both sides and above the faucet body 20 in the open state. Moreover, each connection port 2 through the above-mentioned "large work port"
The attachment / detachment work can be performed in a state where the 7, 27, 37, 38, the fastening nut 70, and the like are fully observed. Therefore, even in the case of the former (3), the construction and maintenance of the embedded faucet 12 can be efficiently performed.

In each of the first, second and fourth aspects of the invention, for example, as in the second example of FIG. 5A, the rib 60 is used.
It is also possible to provide a fixing flange 61 or the like at the end portion of the above and fix the fixing flange 61 or the like to the mounting portion 18 by a method such as screwing. In this case, since it is not necessary to use the stay 40, the number of parts required to install the embedded faucet 12 can be reduced. Further, in each of the first, third and fourth inventions, as in the third example of FIG.
It is also possible to provide a rib 60 at a portion which does not face the mounting portion 18 in 0 and to indirectly fix the rib 60 to the mounting portion 18 via the stay 40, or to fix the rib 60 directly to the mounting portion 18. it can.

Further, in the invention of claim 1 , FIG.
As in the fourth example in (c), the rib 60 is
It may be one that reinforces the individual protruding portions (27, etc.) of 0. Further, in each of the present invention, the fixing mode between the rib 60 or the stay 40 and the mounting portion 18 is not limited to the "screw stop" of this example. For example, as in the fifth example of FIG. 5D, the hook 60 is attached to the rib 60 or the stay 40.
2 may be provided, and the hooking portion 62 may be hooked on the hooked portion 63 provided on the mounting portion 18.
