Description

  The present invention relates to a drain trap used in a bathroom or the like, and more particularly, to a drain trap that relaxes the blockage of drainage by hair or the like collected by a hair catcher and improves cleanability.

  Conventionally, for example, foreign matters such as hair flowing out from a washing place in a bathroom are collected by a hair catcher provided below the eye plate of the washing place. If this foreign matter is left unattended, scales, soap scum, rinses, etc. may adhere to it, causing slime generation and reducing drainage performance. I often removed it by hand.

As an example of means for alleviating this unpleasant work, a drain trap as shown in FIG. 6 has been proposed (see Patent Document 1). In this drain trap 1, when the bath water is drained into the trap, a vortex is formed in the drain trap using this stream, and the hair attached to the hair catcher 4 is peeled off by this vortex to the central portion. It is a summary. Thereby, since the state which hair does not adhere except the center part of a hair catcher is maintained, water flow becomes favorable and the frequency of hair removal work can be reduced.
Japanese Patent No. 3886055

  However, although the drainage trap shown in Patent Document 1 can alleviate the blockage of the hair catcher, there is a problem that the structure of the trap body is complicated and the number of parts is large, so that it takes time to clean the parts other than the hair catcher. . Moreover, since the trap body has a special structure, there is a problem that such a function cannot be added to an already installed bathroom.

  This invention is made | formed in view of the said subject, and it aims at providing the drain trap which can ease the obstruction | occlusion of a hair catcher with a simple structure easily.

In order to achieve the above object, the present invention has the following configuration.
(1) A sealing portion having an inlet and an outlet, a sealing tube inserted and suspended in the sealing portion, and a hair catcher disposed above the sealing tube,
The drain trap which has the fin which the above-mentioned inflow port flows in bathtub drainage, the above-mentioned outflow port drains and flows out through a sealing wall, and the above-mentioned sealed cylinder projects below the lower end.
(2) A drainage trap according to item (1), wherein the fin is a molded body that continues to the inner wall of the sealed water tube.
(3) A drainage trap according to item (1) or (2), wherein a plurality of fins are provided and arranged at equiangular intervals in plan view.
(4) The drainage trap according to any one of items (1) to (3), wherein the height of the bottom surface of the hair catcher is higher than the height of the upper end portion of the sealing wall portion.
(5) In any one of items (1) to (4), a rectifying plate formed in a substantially circumferential direction is provided on the upper surface of the edge of the hair catcher, and a handle is provided in a portion of the rectifying plate. Drain trap.

According to the drainage trap of the present invention, by providing a fin that protrudes downward from the lower end of the sealing tube inserted and suspended in the sealing portion, the water level in the sealing tube is raised each time the bathtub water is drained, The hair catcher provided above the sealing tube can be washed. As a result, it is possible to make it easy to wash away dirt, soap residue, rinses, etc. adhering to the hair catcher while peeling off the hair attached to the hair catcher. It can be easily discarded when foreign objects (hair etc.) are discarded. In addition, since it is difficult to block the hair catcher with these foreign substances, the frequency of removing the foreign objects from the hair catcher can be reduced, and the drainage can be cleaned more easily.
In the case where the fin is formed into a molded body that continues to the inner wall of the sealed water tube, the effect of increasing the water level can be further enhanced, and a swirling flow can be generated in the sealed water tube, so that the hair catcher can be washed more effectively.
When a plurality of fins are provided at equiangular intervals, a substantially constant water level raising effect and turning effect can be obtained regardless of the installation direction of the sealing cylinder (the direction of the sealing cylinder in the installed state) in plan view. Thereby, when installing a sealed water bottle, it can install freely, without minding the installation direction.
If the height of the bottom surface of the hair catcher is higher than the height of the top end of the sealing wall, the bottom surface of the hair catcher will not be immersed in the sealing water except when draining the bathtub, so the hair catcher will always be immersed in the sealing water. Generation | occurrence | production of slime etc. by doing can be suppressed.
While providing a baffle plate formed in a substantially circumferential direction on the upper surface of the edge of the hair catcher and providing a handle on one stroke of the baffle plate, it is difficult for hair flowing from the washing place to be caught by the handle, The hair catcher can be easily attached and detached, and the hair catcher can be easily cleaned.
Moreover, in the present invention, it is possible to have the above effect without changing the main body of the drain trap only by changing the shape of the sealing tube and the hair catcher. Also useful.

First, an example of the drain trap of the present invention will be described with reference to FIG.
FIG. 1 is a schematic cross-sectional view of an embodiment of a drain trap provided in a bathroom. The drain trap 1 is installed below the bathtub 30 and the washing place 31, and includes a sealing part 3 having an inlet 11 through which water from the bathtub 30 flows in and an outlet 12 through which the water is discharged, and the sealed water. A sealing tube 2 inserted and suspended in the section 3 and a hair catcher 4 disposed above the sealing tube 2 are provided. Moreover, the fin 6 which protrudes below is provided in the sealing cylinder lower end 2a.
The drainage of the bathtub 30 flows in from the inflow port 11 and is discharged from the outflow port 12 through the sealed wall portion (bank portion) 14 in the sealed water portion 3. Further, after the foreign matter such as hair is removed by the hair catcher 4 installed in the drainage basin 5 of the washing place 31, the waste water of the washing place 31 flows into the sealed water part 3, and the sealed wall part (bank part) 14. And then discharged from the outlet 12.

The sealed water part 3 is provided with an inlet 11, a sealed wall part (bank part) 14, and an outlet 12, and between the inlet 11 and the sealed wall part (bank part) 14, there is a seal. The water bottle 2 is inserted and suspended. The inflow port 11 is disposed at a position lower than the height of the upper end of the sealed wall portion (bank portion) 14 and is disposed so as to be always lower than the liquid level of the sealed water portion 3.
The cross-sectional shape of the inflow port 11 is not particularly limited, but any shape such as a circular shape, a semicircular shape, an elliptical shape, a substantially circular shape, or a substantially polygonal shape can be used.
In addition, the flow path area of the inlet 11 is preferably smaller than the flow path area of the outlet 12. This is because if the flow path area of the inflow port 11 is larger than the flow path area of the outflow port 12, the water discharged from the bathtub 30 cannot be completely discharged from the outflow port 12, and a part of the drainage passes through the sealing cylinder 2. This is because it flows into the drainage basin 5 and then flows back into the washing place 31 and overflows.

  The outlet 12 discharges the waste water from the bathtub 30 and the washing place 31 flowing into the drain trap 1 to the outside of the drain trap 1 and is arranged at the upper end portion of the sealing wall portion (bank portion) 14. The position in the height direction of the outlet 12 (height of the sealing wall portion (bank portion) 14) is 50 mm or more higher than the bottom end 2a of the sealing tube in order to ensure a sealing height of 50 mm or more. Is preferred.

  In addition to the inflow port 11 and the outflow port 12, the sealed water unit 3 is provided with a sealed tube 2 having an upper portion opened and a lower portion immersed in water. The material of the sealing cylinder 2 is not particularly limited, but a synthetic resin or metal can be used. The base material may be mixed with an antibacterial agent, or the base material surface may be coated with the antibacterial agent. A coating having a water repellent function or a hydrophilic function can also be applied.

A fin 6 is provided at the lower end 2a of the sealing tube, and by this fin 6, a part of the flow of bathtub drainage entering from the inflow port 11 is directed from the direction toward the outflow port 12 (horizontal direction) toward the hair catcher 4 ( In the vertical direction, the water level in the sealed cylinder 2 is raised.
The fin 6 protrudes downward from the lower end 2a of the sealed water tube. Note that the lower end of the sealed water cylinder described here is the lower end of a portion having a function as a cylinder.
The positions of the fins 6 are preferably provided on the downstream side when the water sealing tube 2 is divided into the upstream side and the downstream side in the flow of water (upstream half side surface and downstream half side surface). The shape of the fin 6 is not particularly limited, but any shape such as a semicircular shape, a substantially semicircular shape, a triangular shape, a quadrangular shape, or a substantially polygonal shape can be used.
Moreover, as shown in FIG. 1, it is preferable that the fin 6 inclines downward toward the inflow port 11 side. Furthermore, it has a round shape from the lower end of the sealing cylinder 2 to the lower end of the fin 6 and inclines. It is preferable. By doing in this way, a water flow can be changed into an ascending water flow smoothly.

Next, the shape of an example of the sealing cylinder 2 used for the drain trap 1 of the embodiment of the present invention will be described in more detail with reference to FIG.
The height (H) of the fin 6, which is the length from the lowermost end of the fin 6 to the lower end 2 a of the sealing cylinder, is arbitrarily set according to the distance between the lower end 2 a of the sealing cylinder and the bottom surface of the sealing part 3. Can do. For example, when the distance between the lower end 2a of the sealing tube and the bottom surface of the sealing portion 3 is 10 mm, the height (H) of the fin 6 is preferably 3 to 9 mm, and more preferably 5 to 8 mm. This is because if the fins 6 are shorter than 3 mm, the effect of increasing the water level gradually decreases, and if the fins 6 are longer than 9 mm, foreign matters such as hair contained in the drainage of the bathtub 30 gradually become entangled with the fins 6.

  The horizontal length of the fins 6 (L: the circumferential direction of the water sealing tube 2) is not particularly limited, but preferably about 1/8 to about 1 with respect to the circumferential length of the water sealing tube 2. / 2, more preferably about 1/4 to about 1/3. If the length is less than 1/8, it becomes difficult to create an upward water flow gradually, and if it exceeds 1/2, the amount of water that hits the fins and creates an upward water flow decreases. By adjusting the height (H) and length (L) of the fin 6, it is possible to arbitrarily set the width of the water level rise in the sealed tube 2.

  The position of the inclination of the fin 6 as viewed from the inlet 11 side may be provided so as to be the same height on the left and right with respect to the bottom surface of the sealing portion 3, but in FIG. ) To the inlet 11 and the side far from the inlet 11 (b), the fin is inclined so as to gradually increase. If it makes such a shape, when the waste_water | drain of the bathtub 30 will collide with the fin 6, it will be lifted from the low position (a) of the inclination of the fin 6 to a high position (b), and it will raise along the inner wall of the sealing cylinder 2 A flow is generated. As a result, a swirl flow (plan view) is generated in the sealed water cylinder 2 and the hair catcher 4 can be cleaned more effectively.

As shown in FIG. 3, the fins 6 can be continuously provided from the lower end 2 a of the sealed water tube to the inner wall surface of the sealed water tube 2. In this case, it is preferable to arrange the fins 6 so as to gradually increase from the lower end side toward the upper end side. By adopting such a shape, a part of the drainage received at the lower end of the fin 6 can be easily guided into the sealed cylinder 2, and the water level in the sealed cylinder 2 is raised to generate a swirl flow better. be able to.
In FIG. 3, the fin 6 protrudes from the inner wall surface of the water seal tube 2, but is not limited to such a shape, for example, on the side surface portion of the water seal tube 2, from the lower end upward. A spiral bellows-shaped pleat may be provided.

  The installation angle of the fin 6 (the angle formed by the inner wall surface of the sealing cylinder 2 above the fin and the fin 6) is preferably approximately 90 ° to 170 °, more preferably 110 ° to 150 °. Further, the installation angle of the fin 6 may be the same angle from the lower end portion to the upper end portion of the fin 6, but the angle of the lower end portion of the fin 6 may be large and gradually decreased toward the upper end portion.

1 to 3, one fin 6 is provided, but a plurality of fins 6 may be provided.
FIG. 4 is a schematic view of an embodiment of the water sealing cylinder 2 provided with a plurality of fins 6, and shows a case where four fins 6 are provided.
When a plurality of fins 6 are provided in this way, it is preferable to provide each fin 6 at equiangular intervals in plan view. In consideration of formability, the fins 6 are preferably arranged at positions that do not overlap in plan view.
When a plurality of fins 6 are provided at equiangular intervals, it is difficult to be affected by the direction of the sealing cylinder 2, and a substantially constant water level rise width and turning performance can be obtained regardless of the direction of installation. The number of fins 6 is not particularly limited, but is preferably about 3 to 6.

  A hair catcher 4 is detachably installed above the sealing tube 2, and the waste water from the washing place 31 is removed from the foreign matter such as hair by the hair catcher 4 and then inside the sealing portion 3 of the drain trap 1. Flow into.

An example of the hair catcher 4 that can be suitably used for the drain trap 1 of the embodiment of the present invention will be described with reference to FIG. FIG. 5 is a schematic view of an example of a hair catcher used in the drain trap of the present invention.

The shape of the opening portion of the filter portion 7 may be any shape as long as it can capture solid matter such as hair. For example, a large number of circular, substantially circular, elliptical, polygonal, and substantially polygonal holes are formed through it. It is also possible to use a comb or mesh. Moreover, it can also be made the shape which provides a grating | lattice radially from the bottom face center part of a filter.
1-12 mm is preferable and, as for the hole diameter (mesh width) of the filter part 7, More preferably, it is about 4-8 mm. When the pore diameter (mesh width) of the filter portion 7 is smaller than the above range, the filter gradually becomes clogged with solids or the like. On the contrary, if the pore diameter (mesh width) of the filter portion 7 is larger than the above range, the solid matter gradually passes without being trapped and accumulates in the vicinity of the outlet of the drain trap 11 at the rear stage or in the drain pipe 20. This is because the risk of blockage of the piping increases.

  The height of the bottom surface of the filter unit 7 is set at a position higher than the height of the sealing wall portion (bank portion) 14, and preferably, the height of the sealing wall portion (bank portion) 14 is as follows. The position is about 1 to 10 mm higher, more preferably about 2 to 5 mm. Although not shown in FIG. 5, an overflow port for securing drainage from the washing place 31 when the hair or the like is blocked can be provided in a portion of the filter portion 7 of the hair catcher 4. In this case, the height of the upper end portion of the overflow port is preferably provided at a position higher than the edge portion 8.
