Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing an embodiment of a bathroom drainage pipe structure of the present invention, and FIG. 2 is a cross-sectional view of an oval pipe used for a horizontal drawing pipe.

The drain pipe of the bathroom according to the embodiment of the present invention is disposed under the floor of the bathroom unit. On the floor of the bathroom unit, a washing place and a bathtub are provided on a integrally formed waterproof pan, and the bathtub is placed on a part of the waterproof pan. The side of the bathtub 21 facing the washing area 22 is partitioned by an apron 21c. As shown in FIG. 1, the tub 2 is connected to drains 21a and 22a of a bathtub 21 and a waterproof pan 20 in the bathroom.
1. The waterproof pan 20 is drawn laterally between the floor under the building and the pipe to a drainage channel outside the building. An oval tube 10 having an oval cross section is used for the lateral drawing of the drainage pipe, and the oval tube 10 is disposed with a pointed section having a cross section facing downward.

The drain port 21a of the bathtub 13 has a drain plug 21
b and a connection flange 15a. Drain cock 2
1b is adapted to be fitted into the drain 21a,
At the time of drainage in the bathtub 13, the drainage plug 21 b is removed to drain the water. The connection flange 15a is formed by projecting one end of the connection flange 15a in a direction below the floor, and protruding the connection flange 1a.
The oval pipe joint 11 is connected to the pipe joint 12 by connecting the pipe joint 12 to 5a. Oval tube 1 used for horizontal drawing
0 is fixedly connected to the oval-shaped pipe joint 11 and connected to the pipe.

A drain 22a and a connecting flange 15b are provided at a drain 22a of the washing area 22.
The drainage dish 22a is formed in a lattice shape so that water can flow when it is fitted into the drainage port 22a. The connection flange 15b
One end of the connection flange 15b is projected under the floor,
The oval pipe joint 11 is directly connected to the protruding connection flange 15b.

An oval tube 10 used for horizontal drawing is fixedly connected to an oval tube fitting 11 and connected to the oval tube joint 11. Oval tube fitting 1
In 1, the shape of the joint is formed in the shape of the upper part of the oval tube 10 and is joined to the upper part of the oval tube 10 by adhesion. The oval tube 10 used for horizontal drawing of the drainage pipe 5 is opened at an upper part of the joint surface of the oval pipe joint 11 and connected to the upper bathtub 21 and the drainage pipe of the washing place 22. The oval tube 10 closes one end of the pipeline, collects drainage from the bathtub 21 and the washing place 22, and drains the water outside the building. Although not shown, the drain port 22 of the washing area 22 is not shown.
A drain trap can also be provided below a.

[0013] The oval tube 10 has better drainage characteristics than a circular tube. As shown in FIG. 2, the oval tube 10
The oval tube 10 is made of synthetic resin, and the standard cross-sectional shape of the oval tube 10 is such that the radius of curvature of the pointed portion 10a at the lower portion of the oval tube 10 is about half the radius of curvature at the upper portion. For this purpose, the lower channel of the oval tube 10 is narrowed. in this way,
Since the oval tube 10 is disposed with the oval pointed portion 10a facing downward, the cross-sectional area of the channel at the pointed portion is narrower than that of a circular cross-section, so that the flow rate of drainage Demonstrates high sweeping performance even at the bottom slope. That is, by increasing the drainage flow rate, the drainage performance is improved, and the stagnation of the drainage in the horizontal drawing conduit can be reduced.

As described above, the drainage structure of the bathroom of the present invention is as follows.
The oval tube 10 is used for the horizontal drawing of the drain pipe 5, and the oval pipe 10 is disposed with the pointed portion 10 a having a cross-sectional shape facing downward. Since the water is drained at the pointed portion 10a, the water flow speed is increased, the drainage is less likely to stay in the laterally drawn conduit, and the generation of odor of the drainage in the drainage pipe 5 can be suppressed.
There is no odor that escapes from 22a. In addition, since the flow of drainage is good by making the shape of an egg, it is easy to install the device in a place where there is little pipe space under the floor where a pipe gradient cannot be obtained.

[0015]

According to the first aspect of the present invention, in the bathroom drain pipe structure, an oval tube is used as the horizontal drawing pipe, and the oval pipe is disposed with a pointed portion having a cross-sectional shape facing downward. Then, the drainage pipe is drained by the oval-shaped point, so the drainage flow speed increases, the drainage is less likely to stay in the drainage pipe, and the drain pipe generates odor. Can be suppressed and the odor does not leak from the drain. In addition, since the drainage flow is good by making it oval,
