Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a drainage device for a washbasin installed in a bathroom.

[Prior art and its problems]

Conventionally, in this type of washbasin drainage system, as shown in Fig. 4, the drain pipe from the washbasin D is once detoured to the outside, and then enters the space behind the apron surface A again, and the tip is inserted into the drain port B. The piping structure is designed to

When constructing this piping structure, the first, second, third drain pipes 100, 200, 300
By subdividing the first drain pipe 100 into a wall panel 400 constituting the room wall, and incorporating this wall panel 400, both ends of the first drain pipe 100 can be connected directly under the washbasin D. Apron side A
This first drain pipe 10 faces into the space on the back side.
A second drain pipe 200 that connects to the drain fitting of the washbasin D is connected to one end of the first drain pipe 100, and a third drain pipe 300 that is inserted into the drain port b located behind the apron surface A is connected to the other end of the first drain pipe 100. In order to prevent the third drain pipe 300 from being exposed into the bathroom, the construction order must be such that the apron surface A is installed last.

Therefore, piping work is required in parallel with the bathroom assembly construction, which causes problems such as time-consuming piping construction and the necessity of removing the wall panel in the event of a breakdown or inspection.

[Problem that the invention attempts to solve]

The problem to be solved by the present invention is to facilitate the construction and inspection of the drain pipe to the washbasin.

[Means for solving problems]

The technical measures taken to solve the above problems are to provide a first drain pipe on the back side of the apron surface, whose lower end is inserted into the drain port, and to insert the upper end of the first drain pipe into the communication hole opened in the apron surface. The other end of the second drain pipe, one end of which is connected to the drain fitting of the washbasin, is fitted onto the inner surface of the first drain pipe via a sealing material.

[Effect]

The effect of the technical means of the present invention is that by attaching the apron surface, the first drain pipe, which is provided with one end facing the bathroom, is placed in communication with the drain port, and the second drain pipe is connected from the bathroom. A washbasin drain path is formed by connecting a pipe with one end of the first drainpipe to a washbasin fitting of the washbasin.

[Example] Next, an example of the present invention will be described based on the drawings.

The apron surface A is large enough to cover the back surface of the bathtub C facing the washing area B, and is removably attached to the bathtub C via a support fitting (not shown). A first drain pipe 100 is provided for use.

This first drain pipe 100 has an elbow portion 101 at the lower end.
are equipped on the back surface of the apron surface A via the support 3 with flexible tubes each having an elbow-shaped connecting tube portion 102 at the upper end.

Further, this first drain pipe 100 has a connecting pipe section 102.
The tip of the apron surface A is provided so as to protrude into the room from the communication hole 2 opened in the apron surface A, and the apron surface A is provided under the upper edge surface c of the bathtub C via the support fitting (not shown).
When installed, the elbow part 101 is installed in a position such that it is inserted into the drain port b formed in the washing area B, and the drain fitting d of the washbasin D is connected to this connecting pipe part 102 through the sealing material 1. The second drain pipe 200 connected to the bathroom is fitted from inside the bathroom.

The sealing material 1 is formed by extending a brim-like flange 21 at the tip of a cylindrical portion 11 so as to be able to fit into the connecting tube portion 102. Insert the part,
The brim-shaped flange 21 is secured to the tip of the connecting tube portion 102 and provided at the tip of the connecting tube portion 102 .

The lower end of the second drain pipe 200 is press-fitted into the cylindrical part 11 of the sealing material 1 and connected to the connecting pipe part 102 in a watertight manner, and the upper end thereof is connected to the drain fitting d of the washbasin D.

Incidentally, when inspecting this washbasin drainage system, disconnect the connection point E in the middle of the second drain pipe 200 and connect the second drain pipe 200 as shown in FIG.
The apron surface A may be separated from the bathtub C while the lower half 201 of the bathtub C remains connected to the first drain pipe 100. 4 is a makeup seat.

[Effect of idea]

As described above, in the present invention, a first drain pipe whose lower end is inserted into a drain port is provided on the back surface of the apron, and the upper end of the first drain pipe is exposed to a communicating hole opened in the apron surface. One end of the second drain pipe is connected to the washbasin drain fitting and the other end of the second drain pipe is fitted onto the inner surface of the drain pipe via a sealant, so the pipe can be installed completely from indoors. Easy to do. Furthermore, by uncoupling the second drain pipe from the washbasin drain fitting and then removing the apron surface from the bathtub, the washbasin drain pipe can be easily inspected from the room, which is convenient.

Furthermore, it is economical because the piping can be short, and the piping work is simpler because the lower end of the second drain pipe from the washbasin that constitutes the piping can be press-fitted into the connecting pipe part of the first drain pipe. It also has the advantage of being standardized.

Thus, the intended purpose can be achieved.
