Further, the connecting pipe 13 may be connected to the water tap 7 along the side surface 12b of the back side protrusion 12 within the wall recess 11, as shown by the chain line in FIG.

[Problem that the invention attempts to solve]

However, the conventional built-in wash basin 1 has the following problems related to the connecting pipe 13.

It was necessary to install the connecting pipe 13 between the faucet fitting 3 and the faucet 7 through the vertical panel portion 5, which required opening work.

Also, as shown in solid lines in Figures 4 to 6, the connecting pipe 1
3, the back surface 12 of the back side convex portion 12
A large space for the piping is required between the vertical wall surface 11a of the wall recess 11, and the wall surface needs to be thicker by that amount.

On the other hand, when connecting the connecting pipe 13 as shown by the chain line in FIG. 4, it was necessary to increase the width of the wall recess 11 (width in the left-right direction in FIG. 5) by that amount.

Furthermore, in any piping method, the connecting pipe 13
is arranged in the wall recess 11, and when installing the hand basin 1, the connecting pipe 13 is placed inside the wall recess 1.
There were accidents such as damage caused by contact with each wall of 1.

In addition, condensation often occurs in the connecting pipe 13, and in that case, there is a risk that the condensed water may drip and moisten the inside of the wall surface 10.

The present invention improves and eliminates the above-mentioned drawbacks of the conventional technology, and allows the wall thickness or the width of the wall recess to be set as small as possible. To provide a built-in wash basin that is free from the risk of the inside of the wall becoming damp due to condensed water.

[Means for solving problems]

The means of the present invention for solving the above problems are as follows:
A recessed type basin in which a water supply faucet is provided on the upper side of a hand-washing space formed in a vertical panel part, and a protrusion on the back side of the hand-washing device is buried in a recessed part of the wall to enable hair washing, etc. in the hand-washing space. In the hand wash basin, a conduit groove for storing pipes is formed between the four peripheral frames of the vertical panel portion and the rear convex portion, and the conduit groove is formed immediately below the conduit groove along the side edge frames of the four peripheral frames. An insertion space is formed through which the lower end of the direct-attached pipe connected to the water faucet is inserted.

In addition, regarding the built-in hand wash basin according to the present invention,
In order to contribute to quick and easy installation work on site, the direct-attached pipes are connected in the factory before being shipped.

[Effect]

As is clear from the embodiments shown in FIGS. 1 to 3,
The direct-attached pipe 33 between the faucet fitting 3 and the faucet 7 is housed in the conduit groove by going around the lower end 25a of the vertical panel part 25 and passing through the pipe insertion space 34.
It does not have a structure in which piping is installed inside the wall recess 11. Therefore, the problems listed above that the conventional built-in wash basin 1 had can be solved all at once.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings. Note that the same reference numerals as in the conventional case represent the same members.

〔Example〕

FIG. 1 is a vertical sectional view showing a built-in wash basin 21 according to the present invention, and is a sectional view taken along line A-A in FIG. 2, and FIG. 2 is a cross-sectional plan view of the built-in wash basin 21. 3, which is a cross-sectional view corresponding to line B-B in FIG.
The figure is a perspective view of the built-in wash basin 21 seen from the back side. This built-in wash basin 21 includes a horizontal part 24 for installing the wash basin 2, faucet fittings 3, etc., and a vertical panel part 2 extending vertically from the horizontal part 24.
5, and that the vertical panel portion 25 has a hand-washing space 26, and the water tap 7 is disposed above the hand-washing space 26, as in the conventional case. Therefore, this wash basin 21 has a vertical panel section 2.
A direct-attached pipe 33 is installed between the four peripheral frames of No. 5 and the rear convex portion 32.
A conduit groove is formed for arranging and storing the conduit.
The depth of the conduit groove is slightly larger than the outer diameter of the directly attached pipe 33. Immediately below the conduit groove along the side edge frame, an insertion space 34 is formed through which the lower end of the directly attached pipe 33 is inserted. The insertion space 34 is
There are some changes depending on the type of direct attached pipe 33, but in general
Approximately 15mm is sufficient. Further, the lower end 25a of the vertical panel portion 25 is set slightly lower than the height position of the lower end surface 11b of the wall recess 11 so that the inside of the wall recess 11 is hidden.

A direct-attached pipe 33 that connects the faucet fitting 3 and the faucet 7
is branched from the faucet fitting 3 to form a vertical panel portion 25.
The lower end 25a side of the vertical panel portion 25 is inserted into the insertion space 34 between the vertical panel portion 25 and the wall surface 10, and is formed between the inner surface of the side edge frame of the vertical panel portion 25 and the side surface 32b of the back side convex portion 32. It is housed in a conduit groove and connected to a water tap 7.

With such a piping structure, there is no need to arrange the direct-attached pipe 33 inside the wall recess 11, and for example, the back surface 32a of the back side protrusion 32 is connected to the vertical surface 1 of the wall recess 11.
It can be placed close to 1a, and the thickness of the wall surface 10 can be reduced. Further, the width of the wall recess 11 only needs to be large enough to allow the rear side protrusion 32 to fit therein, and there is no need to enlarge the width extra for piping as in the conventional example shown by the chain line in FIG. Furthermore, there is no need to form through holes for piping in the vertical panel portion 25. Furthermore, when installing the washbasin 21, each inner wall surface in the wall recess 11 and the direct-attached pipe 33 may come into contact and be damaged, or the direct-attached pipe 33 may be damaged by other objects during the distribution process, such as during transportation after factory shipment. There is no possibility that the directly attached pipe 33 will be damaged due to contact.

By the way, in the main wash basin 21, by operating the faucet handle 8 in the opening direction, water supplied from the water supply pipe 9 is supplied to the water faucet 7 via the direct-attached pipe 33, and is squirted into the wash basin 2. The user can also put his/her head in and out of the hand-washing space 26, and in addition to washing his hands, it is also possible to wash his hair.

The present invention is not limited to the above-described embodiments, and the shape and size of the washbasin, the type and number of faucet fittings, the position of the handle, etc. can be changed as appropriate.

[Effect of idea]

Since the present invention has been described in detail above, it has the following effects.

There is no need to open a through hole for passing a direct-attached pipe through the front side of a vertical panel in a washbasin.

There is no need to unnecessarily increase the thickness of the wall where the washbasin is installed.

There is no need to unnecessarily increase the width of the wall recess in which the protrusion on the back side of the washbasin is buried.

Even if a direct-attached pipe is attached to the handwash basin at the time of shipment from the factory, there is no risk of it being damaged by contact with other objects during the subsequent distribution process or when installed on a wall.

Even if dew condensation occurs on the direct-attached pipe after the handwash is installed, the condensed water is guided out of the wall surface from the lower end of the direct-attached pipe, and there is no risk of dampening the inside of the wall surface.
