Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a flat drainage basin disposed between an equipment unit and a floor slab.

Conventionally, there is a drainage basin of this type as disclosed in Japanese Utility Model Publication No. 56-51101.

This conventional product has a shoe rail height of 101 for the door 100.
Due to the need to lower the lower surface of unit A and floor slab D
A flat box 103 having one drainage port 102 is disposed between the drain and the drain, and the box 103 receives the waste water and sends it to the drain trap 104. (Fig. 7) However, in the case of this box 103 (drainage basin), it is only intended for drainage from a washing area, and when used in a facility unit where drainage from wash basins, washing areas, and bathtubs is concentrated, it is necessary to use only one drainage basin. Since such waste water is concentrated at the port 102, the waste water cannot be discharged smoothly, resulting in problems such as very poor drainage efficiency and backflow of waste water to the washing area.

The present invention was developed in view of the above-mentioned conventional circumstances, and its purpose is not only to quickly discharge wastewater from washing areas, bathtubs, and basins even when it is concentrated, but also to achieve miniaturization. Moreover, it is an object of the present invention to provide a drainage basin for an equipment unit that can reduce the height of the shoe rail on the door of the equipment unit.

Its basic structure is that ``a partition wall is provided inside to form three flow paths to prevent the washbasin drainage, bathtub drainage, and washing area drainage from colliding with each other.''

Hereinafter, embodiments of the present invention will be described based on the drawings.

In the figure, B indicates a flat drainage basin main body, which has a flat shape with a hollow interior that can be installed between the equipment unit main body A and the floor slab D, and has a first inlet 2 on the opposite side. Then, the outflow port 1 is opened, and a large diameter port 3 is opened in the upper surface at a portion outside a certain range connecting the first inflow port 2 and the outflow port 1.

The first inlet 2 is formed by protruding from the side surface of the drainage basin main body B a connecting cylinder part 2a having a screw 11 screwed on its inner circumferential surface, and the outlet 1 is formed by similarly having a screw 11 screwed on its inner circumferential surface. It is formed by protruding the connecting cylindrical portion 1a.

The large-diameter opening 3 is a partition wall 4 installed in the drainage basin main body B.
A connecting flange 13 is divided into a second inlet 3a and a third inlet 3b, and has a tap hole at the mouth edge.
is formed protrudingly.

The partition wall 4 has a length that does not block the internal space connecting the first inlet 2 and the outlet 1, and divides the inside of the drainage basin body B into three flow paths 8, 9, and 10,
The distal end is bent in a curve toward the outlet 1 side to form a drainage guide surface 4a.

The outflow port 1 is a connection port for a drain pipe 5 that connects to a collective drainage standpipe C in the pipe shaft 1C, and the first and second inflow ports 2 and 3a are a connection port for a drain pipe 6 for a washbasin and a drain for a bathtub, respectively. It is a connection port for the pipe 19, and the third inflow port 3b is a communication port for a washing area.

The equipment unit main body A has a well-known configuration in which a wall panel 2A is installed around the periphery of the floor pan 1A, and the upper part is covered with a ceiling panel. (not shown), and a concentration opening 15 opened on the lower surface of the recessed part 14 formed in the washing area 1A' portion facing the apron plate 12.
The flat drainage basin main body B is connected in a suspended manner via a mounting flange 17 placed on a rubber gasket 16 fitted to the edge.

The mounting flange 17 has an annular shape with a slightly larger diameter than the concentration port 15, and has flange portions 17a protruding inward at necessary locations, which are disposed above the concentration port 15 and connected to the flange portion 17a. By fixing the flange 13 with the screw 18, the drainage basin main body B is suspended below the concentration port 15.

At this time, the third inlet 3b portion is located directly below the L-shaped drain plate 21 which is hooked on the draining protrusion 20 formed to protrude from the floor pan 1A below the apron plate 12 of the bathtub.

Then, the bathtub drain pipe 19 is fitted into the third inlet 3b of the flat drainage basin main body B, and the first inlet 2
Connect the washbasin drain pipe 6 to the outlet port 1, and connect the drain pipe C to the outlet port 1.
The drain pipes 5 connected to the drain pipes 5 are connected to each other.

Therefore, the wastewater from the bathtub 3A, the washbasin, and the washing area 1A' flows into the respective channels 8, 9, and 10 without interfering with each other, and is quickly guided to the outlet 1 via the drainage guide surface 4a and drained. It is discharged to trap 7.

As described above, the present invention provides three internal partition walls.
In addition, the tip of the partition wall that divides the interior is bent toward the outlet side to form a drainage guide surface, so bathtub drainage and washing area drainage are guided by the guide surface and flow to the outlet. As the three streams do not interfere with each other and are drained as one stream, the drainage efficiency is very high, and even though it is small, it can be drained from the bathtub, washing area, and basin at the same time. This method does not cause backflow of wastewater to the washing area or delay in draining time, and is effective for equipment units where three wastewaters are concentrated.

Moreover, since it is flat, it can be interposed between the equipment unit body and the floor slab, so there is no need for the shoe rail height of the unit body to be high and the step in and out of the unit body to be high. Another advantage is that it can be installed low on the floor slab.

Thus, the intended purpose can be achieved.
