Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a drain trap that is attached to the tip of a drain pipe introduced into a drainage basin to deodorize the drainage basin.

[Background technology]

Conventionally, drainage basins have been buried underground, and wastewater discharged from households is treated by flowing into the basin through drain pipes. However,
Conventional drainage basins do not have traps, so there is a problem that the bad odor inside the drainage basin flows back into the home through the drain pipe, and if a trap is connected between the drain pipe and the drainage basin. However, there was a problem in that it was difficult to clean the sediment that had accumulated inside the trap.

[Purpose of invention]

The present invention was developed in view of the above points, and it is possible to attach a trap to the end of a drain pipe to prevent bad odors from flowing back into the home.
The object of the present invention is to provide a trout trap whose interior can be easily cleaned.

[Effect of idea]

That is, the trout trap of the present invention has a guide piece 2 extending upward from the upper edge of one side of a bottomed cylindrical trap body 1, and an insertion cylinder part into which a drain pipe 3 is inserted into the outer surface of the guide piece 2. 4 is formed, and a partition plate 6 is suspended from the lower surface of the cover body 5 to form an odor-proof cover 7, and both sides of the partition plate 6 of the odor-proof cover 7 are connected from both side edges of the guide piece 2 of the trap body 1 to the trap body. The deodorizing cover 7 is inserted into the trap body 1 so as to be slidable up and down by fitting into the guide groove 9 which is concave in the middle part of the trap body 1, and the opening on one side of the trap body 1 formed between the guide pieces 2. The part 10 is closed with the cover body 5 of the deodorizing cover 7, and a flow path 12 is formed between the lower end of the partition plate 6 and the bottom surface of the trap body 1.
An opening 13 formed at the upper edge of the trap body 1 opposite to the guide piece 2 communicates with the inside of the insertion tube 4 through a flow path 12.
The inside of the trap is divided into upper and lower parts by a partition plate 6 to form a flow path 12 between the bottom surface of the trap body 1 and the partition plate 6, and a drainage inflow section 14 from the drain pipe 3 is formed on one side of the trap body 1, and on the other side. By forming a drainage outflow part 15 with an open upper end on one side of the trap body 1, the drainage flowing into the drainage basin from the drain pipe 3 is transferred to the trap body 1.
The odor cover 7 prevents the odor from flowing back into the drain pipe 3.
By pulling the trap upward from the trap body 1, the upper end opening of the trap body 1 is opened wide, so that the inside of the trap body 1 can be easily cleaned.

The present invention will be explained in detail below with reference to Examples. As shown in FIGS. 1 and 2, the trap body 1 is formed into a substantially cylindrical shape with a bottom, and a guide piece 2 extends upward from the upper edge of approximately one half of the trap body 1. A cylindrical insertion tube portion 4 into which a drain pipe 3 is inserted is formed on the side surface of the drain tube 2 . A fitting protrusion 16 for airtightness as shown in FIG. A guide groove 9 curved to open toward the trap body 1 is long and concave in the vertical direction until it reaches a substantially middle portion of the trap body 1.
On the other hand, the deodorizing cover 7 has a downwardly curved cover body 5.
A partition plate 6 is formed to hang down from the lower surface. The lower end edge of the cover body 5 is provided with a fitting groove 17 that fits with the fitting protrusion 16 with good airtightness, and a handle 18 is formed extending from the front side of the cover body 5. Further, on the front side of the partition plate 6, a pair of left and right rib pieces 19 are provided vertically and long. The deodorizing cover 7 thus formed is inserted into the trap body 1 by inserting and fitting both sides of the partition plate 6 into the guide groove 9 of the trap body 1 from above, so that it can be slid up and down and detached from the trap body 1. When the deodorizing cover 7 is completely fitted to the trap body 1, the opening 10 on one side of the trap body 1 formed between the guide pieces 2 is inserted into the cover body 5.
The trap body 1 can be covered with airtight material to close the trap body 1 with good airtightness, and a flow path 12 is formed between the partition plate 6 and the bottom surface of the trap body 1. In addition, in this case, an opening 13 is formed at the upper end of the trap body 1 on the opposite side from the guide piece 2;
and the inside of the insertion tube 4 are communicated via a flow path 12.

Then, as shown in FIG. 7, the trap body 1 is attached by inserting the insertion tube 4 of the trap body 1 into the tip of the drain pipe 3 introduced into the drain basin 20. The deodorizing cover 7 is normally inserted into the trap body 1 and used. The waste water W discharged from each household flows down from the drain pipe 3 into the trap body 1 and accumulates as shown in the figure, and is collected in the flow path 12.
The wastewater flows out from the wastewater outflow portion 15 into the drainage basin 20 through the wastewater outflow portion 15. With this configuration, the air in the drain basin 20 and the air in the drain pipe 3 are prevented from flowing by the waste water W accumulated in the trap body 1, and the bad odor in the drain basin 20 flows inside the drain pipe 3. There is no possibility that the water will flow back into the home. In addition, since the fitting groove 17 of the deodorizing cover 7 and the fitting protrusion 16 on the upper edge of the guide piece 2 are fitted with good airtightness, the bad odor in the drainage basin 20 is discharged from the gap between these parts to the drain pipe 3.
It cannot even go inside. By using the trap, there is drainage W inside the trap body 1.
The dirt inside will settle and accumulate, but in that case, hold the handle 18 of the deodorizing cover 7 with your hand and pull the deodorizing cover 7 upwards, fully opening the top opening of the trap body 1, and opening it wide. More trap body 1
can be cleaned. 21 in FIG. 7 is a packing material. Further, as shown in FIG. 8, the guide piece 22 is extended rearward and obliquely upward from the upper surface of the insertion tube 4, and the deodorizing cover 7 is attached to the trap body 1.
The deodorizing cover 7 may be easily inserted by moving the cover body 5 of the deodorant cover 7 downward while coming into contact with the guide piece 22 when inserting the deodorizing cover 7 from above.

Furthermore, FIGS. 9 to 12 show other embodiments. This trap has an insertion tube 4 protruding from the center of the guide piece 2 to form a fitting protrusion 16 along the entire length of the upper edge of the guide piece 2, as shown in FIG. It is formed by bending the flat upper surface of the cover body 5 toward the back side. In addition to the above effects, this trap can increase the strength of attachment of the trap body 1 to the drain pipe 3.

[Effect of idea]

As described above, the present invention forms an insertion cylinder part on the guide piece, partitions the trap body with the partition plate of the odor-proof cover, and also covers the opening on one side of the trap body formed between the guide pieces of the trap body with the cover of the odor-proof cover. A flow passage is formed between the lower end of the partition plate and the bottom of the trap body, and the opening formed at the upper edge of the trap body opposite to the guide piece is communicated with the inside of the insertion tube via the flow passage. As a result, the trap body is divided by the partition plate into a drainage inflow part on one side of the guide and a drainage outflow part with an opening at the upper end of the guide, forming a roughly U-shaped trap and discharging the inside of the drainage basin. It is possible to prevent the air from flowing backward through the drain pipe inserted into the insertion tube,
In addition, both sides of the partition plate of the odor-proof cover are fitted into the guide grooves of the guide piece, and the odor-proof cover is inserted into the trap body in a vertically removable manner, so that by pulling out the odor-proof cover from the trap body, the trap body opens The trap body can be opened wide and the inside of the trap body can be cleaned easily.
