When water is drained from the floor to a water-sealed deodorant one trap, the water collected in the trap rises between the outer wall surface of the drain pipe and the inner wall surface of the deodorant one, overflows from the drain port, and enters the drain pipe. And drained. In this way, the water-sealed deodorant one trap has poor drainage efficiency because the water rises and overflows from the drainage port, and dust easily adheres to the side wall of the drain pipe. Further, there is a problem that the drainage efficiency is lowered.

Therefore, in the water-sealed deodorant one-trap type drainage mechanism, there is a problem that dust does not adhere to at least the inner wall surface of the drainage pipe.

The present invention for solving the above problems is used in a water-sealed deodorant one trap together with a trap that collects water in an annular shape around an erect drainage pipe, covers the drainage port at the upper end of the drainage pipe, and covers the lower end. Is a deodorant one that submerges the water in the water collected in the trap and seals the upper end side of the drainage pipe with water. When, the water between the outer wall surface of the drainage pipe and the inner wall surface of the deodorant one is circulated around the drainage pipe by the spiral water channel and flows into the drainage pipe from the drainage port, and further, the drainage pipe is further circulated. It is a deodorant one that allows the water that has flowed into the drainage pipe to flow down while circulating around the inner wall surface of the drainage pipe.

Since the deodorant one according to the present invention is provided with a spiral water channel formed by a spiral recess on the inner wall surface, when water is poured into the trap, the outer wall surface of the drainage pipe and the inner wall surface of the deodorant one are formed by the spiral water channel. The water in between can be circulated around the drainage pipe and flowed into the drainage pipe from the drainage port, and the water that has flowed into the drainage pipe can be made to flow down while circling the inner wall surface of the drainage pipe. Compared to Wan, it is possible to suppress the adhesion of dust to the inner wall surface of the drainage pipe during drainage.

It is an exploded perspective view which shows an example of the water-sealed deodorant type one trap which includes a deodorant one, a trap, and a perforated plate. It is sectional drawing explaining the state which when the water is poured into a trap, the water between the outer wall surface of a drainage pipe and the inner wall surface of a deodorant one rises while circling around the drainage pipe by a spiral water channel. It is sectional drawing explaining the state which the water which flowed into a drainage pipe flows down while orbiting the inner wall surface of a drainage pipe.

The water-sealed deodorant one trap 1 shown in FIG. 1 is a drainage mechanism arranged on the floor of a toilet or washroom, a sink in a kitchen, or the like, and is formed in an annular shape around a drainage pipe 20 to be erected. The deodorant one 3 that covers the drain port 200 at the upper end of the drain pipe 20 and the trap 2 that collects water, submerges the lower end in the water collected in the trap 2, and seals the upper end side of the drain pipe 20 with water, and the trap 2. The opening 2a on the upper end side is provided with a perforated plate 4 that is fitted and serves as a lid.

The trap 2 has, for example, a bottomed cylindrical outer shape, and a drain pipe 20 penetrates the bottom portion 2b and stands upright. The drainage pipe 20 has a cylindrical outer shape, and the lower end side thereof communicates with a drainage channel (not shown) outside the trap 2. The height position of the drain port 200 at the upper end of the drain pipe 20 is set below the height position of the opening 2a on the upper end side of the trap 2.
An annular support portion 25 for supporting the perforated plate 4 fitted in the opening 2a is formed in the vicinity of the opening 2a on the inner peripheral surface of the side wall 2c of the trap 2.

The deodorant one 3 has, for example, a cylindrical outer shape of a ceiling wall, and a fixing screw 31 screwed into a screw hole 41 of a perforated plate 4 is formed on the top wall 30. In the illustrated example, one spiral water channel 33 extending upward with a spiral recess is formed on the inner wall surface 32a of the side wall 32 of the deodorant one 3. A plurality of spiral water channels 33 formed by cutting out the inner wall surface 32a in a spiral groove shape may be formed on the inner wall surface 32a.

The perforated plate 4 has, for example, a circular plate-shaped outer shape, and a plurality of drain holes 40 are formed through. A screw hole 41 is formed in the center of the perforated plate 4, and the perforated plate 4 and the deodorizing one 3 are integrated by screwing the fixing screw 31 of the deodorizing one 3 into the screw hole 41. Then, the perforated plate 4 integrated with the deodorant one 3 is fitted into the opening 2a of the trap 2 and is in a state of being supported by the support portion 25 of the trap 2.

Next, as shown in FIG. 2, when water is drained from the water-sealed deodorant one-trap 1 installed on the floor of a toilet or washroom, for example, the water in the water-sealed deodorant one-trap 1 The flow will be explained.
In FIG. 2, a certain amount of water (sealing water) is stored in the trap 2, and the deodorant one 3 integrated with the perforated plate 4 covers the drain port 200 at the upper end of the drain pipe 20 and the lower end is a trap. It is submerged in the water collected in 2. A predetermined gap is formed between the deodorant one 3 and the bottom portion 2b of the trap 2. The odor in the drain pipe 20 is stopped in the deodorant one 3 by sealing water, and does not leak to the outside of the water-sealed deodorant one trap 1.

As shown in FIG. 2, the drainage from the floor flows down from the drainage hole 40 of the perforated plate 4 into the trap 2, so that the drainage pipe 20 is between the outer wall surface 201 of the drainage pipe 20 and the inner wall surface 32a of the deodorant one 3. The water level rises. Here, since the spiral water channel 33 is formed on the inner wall surface 32a of the deodorant one 3, the water between the outer wall surface 201 of the drain pipe 20 and the inner wall surface 32a of the deodorant one 3 is drained by the spiral water channel 33. The water flows around the outer wall surface 201 of 20 and rises.

Then, as shown in FIG. 3, when the water level between the outer wall surface 201 of the drainage pipe 20 and the inner wall surface 32a of the deodorant one 3 exceeds the height position of the drainage port 200, the drainage port 200 to the drainage pipe 20 Water flows in. At this time, since the water flows into the drainage pipe 20 as it goes around the outer wall surface 201 of the drainage pipe 20, even after flowing into the drainage pipe 20, it flows down while orbiting the inner wall surface 202 of the drainage pipe 20. To go.

In the conventional water-sealed deodorant one trap, when the water level in the trap exceeds the height position of the drainage port, it flows into the drainage pipe from a part of the drainage port, so that the water flowing into the drainage pipe is the drainage pipe. It flows only in a part of the inner wall surface of. Therefore, dust adheres to the remaining area in the inner wall surface of the drainage pipe through which water does not flow. Furthermore, dust and the like adhering to the inner wall surface of the drainage pipe more likely to flow only in a part of the inner wall surface of the drainage pipe, whereby water does not flow and remains in the inner wall surface of the drainage pipe. In some cases, a vicious cycle of further dust adhering to the area occurred. As a result, the drainage efficiency of the drainage pipe was lowered due to the adhering dust, and the inside of the drainage pipe had to be cleaned frequently.

On the other hand, as described above, the deodorant one 3 according to the present invention flows down while orbiting the inner wall surface 202 of the drainage pipe 20 even after the water flows into the drainage pipe 20, so that the inside of the drainage pipe 20 is for example. Even if dust adheres to the water, the dust is dropped by the water flowing down while orbiting most of the area of the inner wall surface 202. Therefore, dust does not easily adhere to the inner wall surface 202 of the drainage pipe 20, the drainage efficiency of the drainage pipe 20 does not decrease, and the inside of the drainage pipe 20 does not need to be cleaned frequently.

The deodorant one according to the present invention is not limited to the above example, and the components of the deodorant one 3 shown in the attached drawings are not limited to this, and the effects of the present invention are exhibited. It can be changed as appropriate within the range that can be done.
