Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a trap provided for deodorizing drainage water in a drainage route.

(Prior Art) As shown in Figure 3, a conventional trap has a body a of a trap body a, a trap part d for receiving inflow water introduced from the outside through an introduction pipe b and an elbow c, and a trap part d for receiving inflow water introduced from the outside through an introduction pipe b and an elbow c. A tubular invert part e with an open upper part is provided to receive overflow water and discharge it to the outside.By positioning the tip of the elbow c below the water surface of the trap part d, drainage inside the main body a is prevented. This prevents odor from flowing back into the introduction pipe b.

(Problem to be solved by the invention) In the conventional device described above, the tip of the elbow c enters the trap portion d, so the distance between the elbow c and the trap portion d becomes relatively narrow, and the tip of the elbow c enters the trap portion d. This has the drawback that the trap part d is easily clogged with dirt, and the dirt is deposited in the trap section d, which further impairs the flow.

And if it gets clogged with filth, the glued elbow c
It requires removal and is not easy to clean.

Furthermore, although a drain pipe is connected to the invert part e, its center is eccentric from the center of the main body a, which is circular in plan, and this has the disadvantage of complicating the construction work when a large number of traps are installed.

The present invention aims to solve these drawbacks.

(Means for solving the problem) In the present invention, the main body of the trap has a trap part that receives inflow water from the outside, and an open upper part that receives overflow water from the trap part and discharges it to the outside. In the case where a tubular invert part is provided, the trap part is formed of a curved pipe that detours around the lower outer periphery of the invert part, and a cleaning opening that opens upward is formed at the root of the inflow side of the curved pipe. I decided to do so.

(Function) The inflow water that flows in from the outside through the introduction pipe passes through the trap part, overflows to the invert part, and from there flows out to the drain pipe. Since it is constructed of pipes, there are no narrow areas where filth can get clogged, and sediments do not accumulate easily, allowing for smooth drainage. Even if the inside of the curved pipe becomes clogged, cleaning tools can be removed from the cleaning port at the root of the inflow side. Easy to insert and clean.

(Embodiment) An embodiment of the present invention will be explained with reference to Figs. 1 and 2. 1 is a main body of a trap mass made of synthetic resin and has a substantially cylindrical shape, and 2 is a trap formed on the upper side of the main body 1. At the inlet, there is an introduction pipe 3 outside the inlet 2.
is connected.

Reference numeral 4 indicates a trap portion connected to the main body 1 side of the inlet 2, and 5 indicates an invert portion formed at a location lower than the inlet 2 of the main body 1.

The invert portion 5 is formed into a tubular shape with an open upper end 6, and both ends thereof are formed into cylindrical connecting portions 8, 8 to which a drain pipe 7 is attached, as seen in FIG.

The trap part 4 is formed of a curved pipe having approximately the same diameter as the inlet 2, the middle 4a of which is curved along the lower part of the tubular invert part 5, and the tip 4b of the invert part 4 on the opposite side of the inlet 2. A cleaning port 9 which opens on the side and opens upward is formed in the root portion 4c connected to the inflow port 2.

Reference numeral 10 denotes a lid detachably provided on the cleaning port 9. The main body 1 is normally buried in the ground, but a raised pipe 11 with a lid is connected above it as necessary, and the inside of the main body 1 can be repaired, cleaned, etc. via this.

Inflow water such as sewage flowing from the inlet 2 flows inside the trap section 4 and overflows from its tip 4b to the invert section 5 and is drained.
The pipe is made up of a series of curved pipes that bypass the invert part 5 from the inlet 2 to the overflow, and because the pipe is not opened midway, it flows easily and is less likely to be clogged with dirt.

Further, since a cleaning opening 9 is formed at the root 4c of the bent pipe of the trap section 4, a cleaning tool can be inserted into the opening 9 to push out the clogged material to the tip 4b of the opening for easy cleaning.

Furthermore, since the invert part 5 can be formed through the center of the main body 1, it is easy to center the invert part 5 with the drain pipe, which is convenient for construction.

(Effects of the invention) In the present invention, since the trap part is formed by a curved pipe that detours around the lower outer periphery of the invert part, water can flow easily and sediment is difficult to form, and a uniform circulation area can be obtained. This prevents dirt from clogging, and since a cleaning hole is formed at the root of the trap, if the trap becomes clogged, it can be easily cleaned by pushing the clogged material from the cleaning hole to the end. It has the effect of simplifying construction because it can be placed easily.
