DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage basin device with a trap having a reservoir.

[0002]

2. Description of the Related Art For example, drain pipes from garden pans such as foot washing places installed outside buildings are considered to be part of drainage facilities, and are therefore connected to public sewers. In this case, a trap device is provided in the vicinity of the foot washing place of the drainage pipe so that the odor from the public sewer does not enter the foot washing place via the drainage pipe.

[0003] However, conventionally, in this type of trap device,
There is a problem that soil and the like easily accumulate in the trap tube, and the earth and sand easily penetrate into the drainage pipe on the downstream side after passing through the trap tube and the box body.

[0004] In order to solve these problems,
As described in the specification and drawings of Japanese Patent Application No. 3-213825 filed earlier, the present applicant has a drainage basin body having a cleaning opening formed at the top and a soil reservoir formed at the bottom, An inlet formed on the side of the basin main body for fitting and connecting an upstream drainage pipe, and an outlet formed on the side of the drain basin main body so as to project downward from a height lower than the inlet. And a drainage basin device equipped with a trap, comprising a trap tube fitted and connected to the outlet.

[0005] According to the drainage basin device with a trap described in Japanese Patent Application No. 3-213825, when drainage containing earth and sand flows into the drainage basin main body from the inflow port through the drainage pipe on the upstream side. Such sediment deposits and accumulates at the bottom of the drain basin and accumulates, and only the supernatant liquid flows out through the trap pipe to the drain pipe on the downstream side, and to the trap pipe and the drain pipe on the downstream side. Can prevent the outflow of sediment.

[0006]

However, in the drainage basin device with a trap described in Japanese Patent Application No. 3-213825, it is necessary to remove the sediment accumulated in the soil reservoir from the cleaning opening of the main body of the drainage basin with a cleaning tool. There is a problem that it takes time and effort. In addition, when drainage containing sediment flows into the drainage basin from the inlet, the inflow water flowing from the small-diameter inlet is particularly strong, and such soil is deposited in the reservoir at the bottom of the drainage basin body. There is a problem that the sediment flows directly into the trap tube without being sedimented and sedimented and deposited in the trap tube.

The present invention has been made in view of the above points, and can prevent odor from flowing from a drain pipe on the downstream side such as a public sewer and prevent soil and the like from flowing from a drain pipe on the upstream side such as a foot washing place. An object of the present invention is to provide a drainage basin device with a trap that can be reliably deposited in a reservoir to prevent deposition of soil and the like in a trap tube and that can easily remove deposited soil and the like.

[0008]

According to a first aspect of the present invention, there is provided a drainage basin device with a trap, wherein a cleaning opening is formed in an upper portion,
A drainage basin main body having a bottom formed with a reservoir and having an inlet formed on one side, and an outlet formed on a lower side from a lower position than the bottom of the inlet on the other side, A trap tube fitted and connected to the outlet of the drainage basin body,
In a drainage basin device with a trap, comprising a container which is removably disposed in a soil reservoir portion of the drainage basin main body, an overflow portion of an outlet of the drainage basin main body is formed in a substantially horizontal shape. A shielding wall is formed in the flow portion at a position facing the inlet.

In the drainage basin device with a trap according to the second aspect of the present invention, the shielding wall is formed integrally from the upper edge of the container.

According to a third aspect of the present invention, there is provided a drainage basin device with a trap, wherein the shielding wall portion is integrally provided so as to protrude from an overflow portion of the drainage basin body.

[0011]

In the drainage basin device with a trap according to the present invention, when the wastewater containing the sediment flows into the main body of the drainage basin with a not so strong water from the inlet, such sediment is inserted into and removed from the reservoir of the main body of the drainage basin. Settles and accumulates in a freely arranged container. On the other hand, if wastewater containing sediment flows from the inlet into the main body of the drainage basin with strong force, it may flow directly above the reservoir and directly to the trap pipe side. Collides with the wall formed at the overflow of the outlet of the drainage basin opposite to the inlet, rebounds to the inlet, reduces the water force, and sediment is surely settled and deposited in the container.

[0012] Then, only the supernatant drainage flows out of the surrounding wall portion through the overflow section to the trap pipe, and the outflow of the earth and sand into the trap pipe is reliably suppressed.

Each connection part by fitting is firmly bonded and fixed by an adhesive.

Reference numeral 21 denotes a net-like container for the reservoir which is removably inserted into the reservoir 3 and has substantially the same shape as the inner surface of the reservoir 3. The height of the container 21 is slightly lower than the overflow portion 7 of the outlet 6. From the upper edge of the overflow section 7 side of the container 21, a planar shielding wall 22 is integrally formed so as to face the outflow port 6 and the inflow port 4, and is integrally formed. Is formed so as to face the projecting portion 7a of the overflow section 7. And
The width Lb of the shielding wall 22 is substantially the same as the diameter La of the inlet 4, and the upper end of the shielding wall 22 is formed higher than the inlet 4. A handle hole 23 for a handle is formed at a position slightly higher than the upper end of the outlet 6 at an upper portion of the shielding wall portion 22, and a handle portion 24 is formed at an upper portion of the handle hole 23.

However, a structure in which a shielding wall portion 22a having a width Lb substantially equal to the diameter La of the inflow port 4 may be formed between the overflow windows 32, 32 may be employed. And this container 21
When a is disposed in the reservoir 3 of the drainage basin body 1, when the wastewater containing sediment flows into the drainage basin body 1 from the inflow port 4 with strong water and flows directly to the trap pipe 11 side, It hits the shielding wall portion 22a of the container 21a and rebounds toward the inflow port 4 side, and only the drainage of the supernatant passes through the overflow windows 32, 32 and flows out to the trap tube 11. In this embodiment, a handle hole 23a for a handle and a handle portion 24a are formed as in the previous embodiment.

Further, in each of the embodiments, the net-shaped container 21 is used. However, the container 21 is not limited to the net-shaped one, and various types of containers 21 can be used. Further, in each of the embodiments, the linear recess 5 is formed on one side of the reservoir 3, the overflow section 7 is linear, and the shielding wall 22 is formed in a plane. Even if the overflow portion 7 is formed slightly curved and the shielding wall portion 22 is formed slightly curved, substantially the same effect can be obtained.

In each of the embodiments, the structure in which the shielding wall 22 is formed integrally with the container 21 has been described. However, as shown in FIGS. It is also possible to project from the upper edge of the part 7 integrally. The concealing wall portion 22 is provided so as to protrude facing the inflow port 4 in the same manner as in the above-described embodiment. It is formed higher than 4.

Further, in each of the embodiments, the trap tube 11 is rotatably connected to the outlet 6 of the drainage basin main body 1.
The end of the outflow port 6 may be a mere receiving port, and the trap tube 11 may be adhesively fitted to this receiving port.

[0034]

According to the drainage basin device with a trap according to the first aspect of the present invention, when drainage containing earth and sand flows into the drainage basin body from the inflow port with a not so strong water force, such sediment is drained from the drainage basin. It sediments and accumulates in a container that can be inserted and removed in the reservoir at the bottom of the main body. On the other hand, when the wastewater containing sediment flows into the drainage basin body from the inflow port with a strong force, it flows directly above the reservoir to the trap pipe side. It hits the concealing wall formed at the overflow of the outlet of the basin opposite to the inlet, rebounds to the inlet, reduces the momentum, and the sediment is surely settled and deposited in the container. Then, only the drainage of the supernatant passes through the overflow section around the shielding wall and flows out to the trap pipe, so that the outflow of sediment into the trap pipe can be reliably suppressed.

Further, by lifting the container from the reservoir in the main body of the drainage basin, sediment deposited in the container can be easily removed.
