Description

[Detailed explanation of the invention] [Technical field] This invention is designed to discharge wastewater from sinks and bathrooms in each home from a drain pipe through a drainage basin to a main drainage pipe buried underground. This relates to drainage equipment.

[Background Art] Conventionally, when draining water from the kitchen, bathroom, etc. of each home to the main drainage pipe 10 buried underground, it has been connected to a sink or the like as shown in Fig. 6. The drain pipe 9 is connected to the drain basin 6, and a trap 11 is provided inside the drain basin 6, and the drain pipe 9 is connected to the drain basin 6.
The tip of the drain pipe is inserted into the trap 11, and the waste water flowing in the drain pipe 9 is temporarily collected in the trap 11, and then is allowed to flow from the trap 11 into a drain basin 6 and then into a main drain pipe 10. However,
In this structure, the trap 11 protrudes from the inside surface of the drainage basin 6, so when cleaning the inside of the drainage basin 6, the trap 11 gets in the way and is difficult to clean, especially when the drainage basin 6 is buried. There is a drawback that the trap 11 cannot be installed inside the drainage basin 6 in places where a drainage basin 6 with a small diameter is used due to housing circumstances.

[Purpose of the invention] The present invention was developed in view of the above points, and it is easy to clean the inside of the drainage basin because the entire trap does not protrude into the drainage basin. It is an object of the present invention to provide a drainage device in which a trap can be installed without any problem even in the case of a drainage basin.

[Disclosure of the invention] That is, the drainage device of the present invention has an inner plate 2 protruding from the inner surface of the side wall 15 of the drainage basin 6 whose upper surface is open to the ground, and a gap between the inner plate 2 and the inner surface of the side wall 15 of the drainage basin 6. A water reservoir part 3 with an opening on the top is provided, and a drainage basin 6 is provided.
A trap pipe 5 communicating with the inside of the water reservoir 3 projects outward from the side wall 15 of the trap pipe 5, and a drain pipe 9 is connected to the tip of the trap pipe 5 via an elbow 8 whose tip curves upward. Inner plate 2,
By forming the trap 11 with the side wall portion 15 and the elbow 8, the trap 11 is formed in the drainage basin 6.
The above object is achieved by making only the inner plate 2, which is a part of the inner plate 2, protrude.

The present invention will be described in detail below based on illustrated embodiments. 1 to 3 show a drainage basin 6 using a trap body 13 formed separately from the drainage basin 6.
An example in which a trap 11 is formed is shown below.
That is, as shown in FIG. 1, the trap body 13 has a curved inner plate 2 connected to the inner surface of the adhesive face plate 1 to form a water reservoir 3 whose upper surface is open between the adhesive face plate 1 and the inner plate 2. At the same time, a water inlet 4 that opens into the water reservoir 3 is formed in the adhesive face plate 1, and a cylindrical trap pipe 5 that communicates with the water reservoir 3 is connected to the water inlet 4. be. The adhesive face plate 1 has a shape similar to that of a side plate of a cylindrical body that is partially cut out, and has a convexly curved surface 12. When connecting this trap body 13 to the drain basin 6, as shown in FIG.
A part of 5 is opened to form a through hole 7, and a drainage basin 6 is formed.
The trap body 13 is put inside the trap body 13, the trap pipe 5 is inserted into the through hole 7, and the adhesive face plate 1 is adhered to the inner surface of the drainage basin 6 with an adhesive to attach the trap body 13 inside the drainage basin 6.
Here, the curvature of the outer surface of the adhesive face plate 1 is formed to be equal to the curvature of the inner surface of the drainage basin 6, and the adhesive face plate 1 extends outward from the opening of the through hole 7 formed in the drainage basin. In addition, it is possible to completely close the through hole 7 to ensure airtightness, and to provide a sufficient adhesive area so that the trap body 13 can be attached in the drainage basin 6 with good adhesiveness.

The drainage basin 6 is buried underground with its top open, and an elbow 8 whose tip is curved upward is connected to the tip of the trap pipe 5 attached to the drainage basin 6. A drain pipe 9 from each household is connected to the drain pipe 9 through an elbow 18 whose tip is oriented horizontally.
Further, a drain main pipe 10 is connected to the lower part of the drain basin 6. Here, the elbow 8 connected to the trap pipe 5, the inner plate 2 of the trap body 13, and the drainage basin 6
A substantially U-shaped trap 11 is formed with the side wall portion 15 of the drain pipe 9, and wastewater such as kitchen wastewater and laundry wastewater that has been drained from each household through the drain pipe 9 is temporarily stored in this trap 11. The collected wastewater that overflows from the water reservoir section 3 flows down into the drainage basin 6 and then into the main drainage pipe 10. Since the waste water is collected in the trap 11 in this way,
Air circulation between the drain basin 6 and the drain pipe 9 is obstructed, and bad odors are prevented from flowing back into the home through the drain pipe 9. In addition, since the elbow 8, which is a part of the trap 11, protrudes outward from the drainage basin 6, and only the inner plate 2 protrudes into the drainage basin 6, the opening area in the drainage basin 6 must be made large. This makes it possible to easily clean the inside of the drainage basin 6, and even if the drainage basin 6 has a small diameter, a trap 11 can be formed in the drainage basin 6 without any trouble. Furthermore, the trap body 13 can be attached by simply drilling a through hole 7 in the side wall 15 of the drainage basin 6, inserting the trap pipe 5 into the through hole 7, and gluing the adhesive face plate 1 to the inner surface of the drainage basin 6. Because there is a trap, it is easy to install the trap, and there is also a through hole 7 in the middle of the cleaning port pipe (not shown) connected to the main drainage pipe 10.
By providing the trap 11, it is possible to form the trap 11 very easily even in cleaning port sets made by other companies.

In the above embodiment, the trap body 13 formed separately from the drainage basin 6 was used to form the trap 11 in the drainage basin 6, but in Figs. An example is shown in which an inner plate 2 and a trap pipe 5 are provided in a drainage basin 6. That is, the inner plate 2 integrally protrudes from the inner surface of the side wall 15 of the drainage basin 6, and the water reservoir 3 having an open top is formed between the inner plate 2 and the inner surface of the side wall 15. The trap pipe 5 is integrally protruded outward. This embodiment has the advantage that trap construction can be carried out at the same time by simply burying the drainage basin 6 underground. In the one shown in FIG. 5, a part of the connecting pipe 16 at the bottom of the drainage basin 6 and the trap pipe 5 are shared. If the trap pipe 5 has various drainage basins 6 and trap bodies 13 with diameters of 50 mm, 75 mm, etc., the trap pipe 5 can be selected depending on the location where the drainage basin 6 is to be buried.

[Effects of the invention] As described above, the present invention has an inner plate that protrudes from the inner surface of the side wall of the drainage basin, and a water reservoir with an opening on the top surface is provided between the inner plate and the inner surface of the side wall of the drainage basin. A trap pipe that communicates with the inside of the water reservoir is projected outward from the side wall, and a drain pipe is connected to the tip of the trap pipe via an elbow whose tip curves upward. As a result, a trap is formed, and it is only necessary to protrude the inner plate from the inside of the drain basin, and there is no need to protrude the entire trap as in the past, making it easier to clean the inside of the drain basin. Furthermore, even in cases where it is not possible to bury a large-diameter drainage basin due to housing circumstances, the trap can be formed within the drainage basin without any problems.
