Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drainage device that is capable of cleaning the inside of a drainage pipe by connecting a vertical pipe to a drainage pipe buried underground.

[Background Art] Wastewater discharged from kitchens, bathtubs, etc. in homes is now discharged to sewer pipes through drain pipes.
By the way, when cleaning the inside of this drain pipe, conventionally, as shown in FIG. Insert the drain pipe 1
I was trying to clean the inside. However, vertical pipe 2
is connected almost orthogonally to the drain pipe 1, and the drain pipe 1 branches as shown in the figure, so
The cleaning tool inserted through the opening of the vertical pipe 2 has difficulty entering the intended drain pipe 1, resulting in a drain pipe that cannot be cleaned.

[Purpose of the invention] The present invention has been made in view of the above points, and provides a drainage device that allows cleaning tools to be inserted into the drain pipe in any direction and allows for easy cleaning of the inside of the drain pipe. The purpose is to

[Disclosure of the invention] That is, the drainage device of the present invention connects a vertical pipe 2 whose upper surface is open to the ground to the connecting part of a plurality of drainage pipes 1 and 1 buried underground, and drains the inside of the lower part of the vertical pipe 2. is divided into a plurality of parts by the introduction piece 3, an introduction port 4 communicating with the inside of each drain pipe 1 is formed between the introduction piece 3 and the inner surface of the vertical pipe 2, and the introduction piece 3 is inserted from the top of the vertical pipe 2 into each The drain pipe is made to slope downward in one direction, and the above purpose is achieved by inserting a cleaning tool 12 such as a wire into the opening of the vertical pipe 2 by bending it in the one direction of each drain pipe from the inlet 4. It is something.

The present invention will be described in detail below based on illustrated embodiments. Figure 1 and the following shows an example in which the drain pipe 1 is branched into three directions and connected, and the connecting part of the main drain pipe 1 has a cheese 6
is connected. As shown in FIGS. 2 and 3, a mounting opening 7 is provided on the top surface of the cheese 6 to which the three connecting pipes 5 are connected, and the vertical pipe 2 is connected to the top surface of the cheese 6. be. The vertical tube 2 is composed of an upper cylinder 8 formed into a cylindrical shape and a lower cylinder 9 whose lower surface branches into three directions and has an opening.The lower cylinder 9 has a cylindrical portion as shown in FIG. A bowl-shaped cover part 11 is formed extending from the lower part of the cover part 10 and has a downward opening. An introduction piece 3 is formed on the inner surface of this cover part 11 and slopes downward from the center toward each cover part 11 side, and an introduction port 4 is formed between the introduction piece 3 and the inner surface of the cover part 11. There is. Further, the introduction piece 3 is formed to be concavely curved downward.

Therefore, when cleaning the inside of the drain pipe 1, as shown in FIG.
When cleaning the inside of one of the branched drain pipes 1, insert the cleaning tool 12 into the opening of the vertical pipe 2, and then use the cleaning tool 12 to clean the inside of the drain pipe 1. It is inserted into the inlet 4 at the bottom of the vertical tube 2 which communicates with the tube 1. Then, the tip of the cleaning tool 12 comes into contact with the introduction piece 3 and is automatically bent, so that it can be inserted into the target drain pipe 1. Similarly, if you want to clean the inside of the other drain pipe 1, pull out the cleaning tool 12 and insert it through the inlet 4 that communicates with the other drain pipe 1, and you can clean the inside of that drain pipe 1. It is possible. In the above embodiment, an example of the drain pipe 1 branched into three directions was shown, but it is also possible to simply connect the vertical pipe 2 in the middle of the straight drain pipe 1 to have the drain pipe 1 branched into two or four directions. Of course, it is possible to use the cheese 6 and the vertical tube 2, or the cheese 6 and the lower cylindrical body 9 formed integrally.

[Effects of the invention] As described above, the present invention divides the lower part of the vertical pipe connected to the connection part of the drain pipe into a plurality of parts with the introduction piece, and connects the inside of each drainage pipe between the introduction piece and the inner surface of the vertical pipe. The introduction piece is slanted downward from the top of the vertical pipe toward each drain pipe, so that if a cleaning tool such as a wire is inserted into the introduction port from the opening of the vertical pipe, the tip of the cleaning tool will When the introduction piece hits, the cleaning tool is automatically inserted into the target drain pipe, and the cleaning tool can be inserted into any drain pipe for cleaning.
