  When water is drained from the floor or the like to the water-seal deodorant one trap, the water collected in the trap rises between the outer wall of the drain pipe and the inner wall of the deodorant one, overflows from the drain port, and enters the drain pipe. And drained. As described above, the water-seal and deodorant type one trap has a poor drainage efficiency because water rises and overflows from the drain port to drain water, and trash easily adheres to the side wall of the drain pipe. Further, there is a problem that drainage efficiency is reduced.

  Therefore, in the water seal deodorant type one trap type drainage mechanism, there is a problem of preventing dust from adhering to at least the inner wall surface of the drainage pipe.

  The present invention for solving the above-mentioned problem is used in a water-seal and deodorant type one trap together with a trap that collects water in an annular shape around a standing drain pipe, and covers a drain port at an upper end of the drain pipe, and a lower end. Is a deodorant one that is submerged in the water accumulated in the trap and water-sealed the upper end side of the drain pipe, provided with a spiral water channel formed by a spiral recess on the inner wall surface, and water was poured into the trap. 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 to flow into the drainage pipe from the drainage port, This is an odor-preventing one that allows water that has flowed in to flow down while rotating around the inner wall surface of the drain pipe.

  Since the deodorant one according to the present invention includes a spiral water channel formed in a spiral recess on the inner wall surface, when water is poured into the trap, the outer water surface of the drainage pipe and the inner wall surface of the deodorant one by the spiral water channel. Between the drain pipe and the drain pipe, and the water that has flowed into the drain pipe flows down while rotating around the inner wall surface of the drain pipe. It is possible to suppress the adhesion of dust to the inner wall surface of the drainage pipe at the time of drainage as compared with the one.

It is an exploded perspective view showing an example of a water seal deodorant type one trap provided with a deodorant one, a trap, and a perforated plate. It is sectional drawing explaining the state where the water between the outer wall surface of a drainage pipe and the inner wall surface of a deodorant one rises while circling around a drainage pipe by a spiral waterway when water is poured into a trap. It is sectional drawing explaining the state which the water which flowed into the drainpipe flows down while rotating around the inner wall surface of the drainpipe.

  The water-seal deodorant type one trap 1 shown in FIG. 1 is, for example, a drainage mechanism disposed on a floor such as a toilet or a washroom, a kitchen sink, or the like, and is formed in an annular shape around a standing drainage pipe 20. A trap 2 for storing water, a deodorant one 3 that covers a drain port 200 at an upper end of the drain pipe 20 and submerges a lower end of the drain pipe 20 in water collected in the trap 2 and seals an upper end side of the drain pipe 20 with water; A perforated plate 4 which is fitted into the opening 2a on the upper end side and serves as a lid is provided.

The trap 2 has, for example, a cylindrical shape with a bottom and a drain pipe 20 penetrates the bottom 2b to stand upright. The drain pipe 20 has a cylindrical outer shape, and its lower end communicates with a drain passage (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 lower than the height position of the opening 2 a on the upper end side of the trap 2.
In the vicinity of the opening 2a on the inner peripheral surface of the side wall 2c of the trap 2, an annular support portion 25 that supports the perforated plate 4 fitted in the opening 2a is formed.

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

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

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

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

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

  In the conventional water-seal deodorant type one trap, when the water level in the trap exceeds the height of the drain port, the water flows into the drain pipe from a part of the drain port. Flows only in a part of the inner wall surface of the. Therefore, dust adheres to the remaining area on the inner wall surface of the drain pipe through which water does not flow. Furthermore, dust and the like adhering to the inner wall surface of the drain pipe more often flow only in a part of the inner wall surface of the drain pipe, and thereby the remaining water in the inner wall face of the drain pipe through which water does not flow. In some cases, a vicious circle in which dust adhered to the area occurred. As a result, the drainage efficiency of the drainage pipe is reduced by the attached dust, and the inside of the drainage pipe has to be frequently cleaned.

  On the other hand, the deodorant one 3 according to the present invention, as described above, flows down the inner wall surface 202 of the drain pipe 20 even after the water flows into the drain pipe 20, so that the Even if dust adheres to the inside, the dust flowing down while flowing around most of the area of the inner wall surface 202 is dropped. Therefore, refuse hardly adheres to the inner wall surface 202 of the drain pipe 20, the drain efficiency of the drain pipe 20 does not decrease, and the drain 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 accompanying drawings are not limited thereto, and the effects of the present invention are exhibited. It can be changed as appropriate within the range that can be made.
