Description

  The present invention relates to a drainage structure having a hair catcher.

  2. Description of the Related Art Conventionally, a hair catcher that supplements hair, dust, and the like is disposed at a drain outlet formed in a bathroom washroom or the like.

  By the way, since shampoo, rinse, etc. contained in the waste water from a washing place are highly viscous liquids, they easily adhere to supplements such as hair and dust supplemented by a hair catcher. Here, a general hair catcher is formed in a shallow dish shape, and its peripheral portion is mounted on the peripheral portion of the drainage port, and has a large number of water holes for supplementing hair, dust, etc. The formed part is disposed at a position where it does not come into contact with water except when water is passed. However, in such a hair catcher, if a highly viscous liquid such as shampoo or rinse adheres to the hair or dust as described above and it dries, the hair catcher will stick to the hair catcher. In addition, there is a risk that the smooth flow of drainage may be hindered by this highly sticky dirt.

Further, for example, in Patent Document 1, a trap portion for collecting and sealing drainage from the drainage port is formed below the drainage port, and a container-like hair catcher having a water passage hole formed in the drainage port is provided. The lower end part of the hair catcher is disclosed below the surface of the accumulated water in the trap part. However, in this hair catcher, only the lower end of the hair catcher is positioned slightly below the surface of the pool water, and most of it is positioned above the surface of the pool water. When hair, dust, or the like adheres to a water passage hole formed in a portion located above the water surface, problems similar to those of the general hair catcher occur.
JP 2006-2423 A

  The present invention has been invented in view of the above-described conventional problems, and can prevent hair, dust, and the like from sticking to the hair catcher, can easily clean the hair catcher, and the flow of drainage. It is an object of the present invention to provide a drainage structure capable of smoothing water.

  In order to solve the above-mentioned problem, the drainage structure according to the present invention includes a trap-like portion 19 for storing drainage and sealing water below the drainage port 2, and includes a container-like hair catcher 20 that opens upward. The lower portion of the catcher 20 is a water passage portion 23 in which a large number of water passage holes 22 are formed, and the upper portion is a non-open water passage portion 24. The hair catcher 20 is disposed in the drain port 2, and the hair catcher 20 All or most of the water passage portion 23 is located below the water surface of the pooled water 25 in the trap portion 19. In this way, the lower portion of the hair catcher 20 is a water passage portion 23 in which a large number of water passage holes 22 are formed, and the upper portion is a non-opening non-water passage portion 24, thereby constituting the lower portion of the hair catcher 20. Hair, dust and the like are easily collected in the portion 23. Then, all or most of the water passage portion 23 of the hair catcher 20 is positioned below the water surface of the pool water 25 in the trap portion 19, so that all or most of the water passage portion 23 in which hair or the like is accumulated is stored. It can be soaked in the water 25, which makes it difficult for highly viscous liquids such as shampoos and rinses to adhere to the hair accumulated in the water passage 23, and even if they adhere, these highly viscous liquids dry. There is no. Therefore, it is possible to prevent hair, dust, and the like from sticking to the hair catcher 20, whereby the hair catcher 20 can be easily maintained and the flow of drainage becomes smooth.

  A second aspect of the present invention is the first aspect of the present invention, wherein the lower portion of the hair catcher 20 is formed in a net shape to form the water passage portion 23, and the mesh of the water passage portion 23 is used as the water passage hole 22. The mesh of 23a is made larger than the mesh of the upper part 23b. Thus, by making the mesh of the lower portion 23a of the water passage portion 23 larger than the mesh of the upper portion 23b, hair or the like can be prevented from staying in the upper portion 23b of the water passage portion 23. For this reason, the upper portion 23b of the water passage portion 23 can be prevented. In, drainage capacity can be secured by a mesh with a large opening area.

  In the invention according to claim 1, by immersing the whole water-passing part in which the hair or the like is stored and immersing it in the water, it becomes difficult for a highly viscous liquid such as shampoo or rinse to adhere to the hair or the like stored in the water-passing part. Even if it adheres, these highly viscous liquids do not dry, so it is possible to prevent hair and dirt from sticking to the hair catcher. The flow also becomes smooth.

  In addition, in the invention according to claim 2, in addition to the effect of the invention according to claim 1, by making the lower mesh of the water passage portion larger than the upper mesh, hair or the like does not stay on the upper portion of the water passage portion. For this reason, the drainage capacity can be secured by the mesh having a large opening area in the upper part of the water passage part, and this significantly reduces the drainage capacity when a large amount of hair etc. is accumulated in the lower part of the water passage part. Can be prevented.

  An example of the drainage structure of the embodiment of the present invention is shown below. As shown in FIG. 1, the drainage structure of this example drains water from a drainage port 2 formed on a floor 1 of a bathroom washroom.

  An attachment port 5 is formed at the bottom of a recess 4 opened upward on the floor 1 of the washing place constituted by the floor pan 3, and a drain trap 6 is attached to the attachment port 5. The drain trap 6 includes a container-shaped trap body 7 disposed below the attachment port 5, a drain cylinder 8 attached to the trap body 7, and a sealing cylinder 9 inserted inside the trap body 7. 8 and the upper part of the sealing cylinder 9 constitute the drain port 2.

  An upper flange portion 10 protrudes from the outer periphery of the upper end of the drain tube 8, and a lower flange portion 11 protrudes from the inner periphery of the lower end portion. The lower part of the drain tube 8 is screwed into and attached to the opening 12 of the trap body 7, and the peripheral portion of the attachment port 5 is packed with the upper flange portion 10 of the drain tube 8 and the peripheral portion of the opening portion 12 of the trap body 7. The drain trap 6 is watertightly attached to the attachment port 5 by being sandwiched via 13.

  In the lower part of the trap body 7, a container-like reservoir 16 that opens upward is formed. In addition, a discharge port 15 is provided in the outer peripheral wall of the trap body 7, and a drain pipe 17 for discharging the water in the trap body 7 overflowing from the reservoir 16 to the outside is provided in the discharge port 15. Connected. On the lower flange 11 of the drain tube 8, a flange portion 18 provided around the upper end of the water seal tube 9 is placed. The lower part of the sealing cylinder 9 is inserted into the water reservoir 16 of the trap body 7 and is immersed in the drainage accumulated in the water reservoir 16, and the drain port 2 is formed by the lower part of the water seal cylinder 9 and the water reservoir 16 of the trap body 7. A trapezoidal trap portion 19 is provided for collecting and sealing the drainage from the tank. That is, the trap portion 19 of this example is provided in the middle of the drainage flow path leading to the drainage port 2 and is positioned below the drainage port 2.

  A hair catcher 20 is disposed in the drain port 2 constituted by the drain tube 8. The hair catcher 20 is formed in a container shape that opens upward, and an annular portion 21 that constitutes the outer peripheral edge of the hair catcher 20 is accommodated in the drain tube 8, and the annular portion 21 is placed on the flange portion 18 of the water seal tube 9. It is placed. That is, the annular portion 21 is placed on the peripheral edge portion of the drainage port 2 including the upper flange portion 10 of the drainage cylinder 8 via the flange portion 18. The hair catcher 20 may simply be placed on the peripheral edge of the drain port 2, and for example, a locking portion and an outer peripheral surface of the annular portion 21 and an inner peripheral surface of the drain tube 8, respectively. A female screw that is provided with a latched portion and detachably latches the latched portion and the latched portion, and a female screw formed on the outer peripheral surface of the annular portion 21 is formed on the inner peripheral surface of the drain tube 8. The hair catcher 20 may be detachably attached to the drain port 2 by, for example, screwing into the drain port 2.

  As shown in FIG. 3, the hair catcher 20 has a lower portion that has a water passage portion 23 in which a large number of water passage holes 22 are formed, and an upper portion that has no through holes such as the water passage holes 22. In the installed state of the hair catcher 20 shown in FIG. 1, the lower end portion of the non-water passage portion 24 is the upper end of the water reservoir portion 16 (that is, the pooled water 25 accumulated in the water reservoir portion 16). The water passage portion 23 is entirely located below the water surface of the pool water 25 in the pool portion 16 constituting the trap portion 19 and is immersed in the pool water 25. Become.

  The peripheral wall portion 26 of the water passage portion 23 is narrowed so as to have a smaller diameter toward the lower side, and the water passage portion 23 is formed by making the entire lower portion of the hair catcher 20 into a net shape. The water passage hole 22 is configured as described above. That is, a large number of water passage holes 22 are formed across the bottom of the water passage portion 23 and the entire peripheral wall 26. Further, the water passage portion 23 has a mesh of the lower portion 23a larger than that of the upper portion 23b.

  The non-water-permeable portion 24 includes an annular annular portion 21 that constitutes the upper end opening of the hair catcher 20 and a peripheral wall 27 that protrudes downward from the inner peripheral edge of the lower end of the annular portion 21. The inner peripheral surface of the annular portion 21 is a curved surface 28 that is inclined so as to gradually decrease in diameter as it goes downward. The peripheral wall 27 of the non-water-permeable portion 24 is narrowed to have a smaller diameter toward the lower side, and the inner peripheral surface of the peripheral wall 27 is a tapered surface 29 that is inclined downward toward the inner side.

  In addition, a handle portion 30 is integrally projected from the annular portion 21 constituting the upper end portion of the hair catcher 20 upward. The handle part 30 protrudes from two opposing portions of the annular part 21, and each handle part 30 includes an upright part 31 raised upward from the annular part 21, and the opposite side of the center of the hair catcher 20 from the upper end part of the upright part 31. It has a knob portion 32 projecting in the lateral direction of, and has an L-shaped cross section. As shown in FIG. 1, the raised portion 31 of each handle portion 30 protrudes upward from the upper end of the drain tube 8, and the knob 32 of the handle portion 30 is located above the upper flange portion 10 of the drain tube 8. For this reason, the knob part 32 of the handle part 30 protruding upward from the drain port 2 is picked up by a finger and lifted upward, whereby the hair catcher 20 can be easily and cleanly taken out from the drain port 2. In addition, although illustration is abbreviate | omitted, the drainage cover which covers the upper direction of the hair catcher 20 provided in the said drain port 2 in the above-mentioned recess 4 is arrange | positioned.

  The flow of drainage in the drainage structure is shown by the arrow in FIG. That is, the water on the floor pan 3 constituting the floor 1 of the washing place flows into the sealing tube 9 from the recess 4 through the drain tube 8 and then passes through the hair catcher 20 and from the lower end of the sealing tube 9 to the trap body. 7, and then discharged through the space between the peripheral wall of the water reservoir 16 and the sealing cylinder 9, the discharge port 15, and the drain pipe 17. At the time of drainage, the drainage flowing from the upper opening of the hair catcher 20 flows from the upper part to the lower part and passes through a number of water passages 22 in the lower part. Can be supplemented.

  Here, since the upper portion of the hair catcher 20 is a non-opening non-water-permeable portion 24, it is difficult for hair or dust contained in the drainage to be caught on the inner surface of the non-water-permeable portion 24. Further, since the waste water that has flowed into the hair catcher 20 is guided to the water passage 23 along the curved surface 28 of the annular portion 21 and the tapered surface 29 of the non-water passage portion 24, the hair or the like does not pass water in this respect as well. It is difficult to stay in the part 24. Therefore, the hair contained in the waste water flowing into the hair catcher 20 is likely to accumulate in the water passage portion 23 having the water passage holes 22 as shown in FIG. A large amount accumulates on the bottom surface of the lower portion 23a. As described above, the water passage portion 23 of the hair catcher 20 is entirely located below the water surface of the pool water 25 stored in the trap portion 19 and is immersed in the pool water 25. It is difficult for highly viscous liquids such as shampoos and rinses to adhere to the hair accumulated in the lower part 23a of the hair, and even if they adhere, these highly viscous liquids do not dry, so that hair, dust, and the like are attached to the hair catcher 20. It can prevent sticking. Moreover, since the upper part 23b of the water flow part 23 has a mesh larger than the lower part 23a, it is difficult for hair etc. to stay in the upper part 23b. Therefore, in the upper part 23b of the water flow part 23, a mesh with a large opening area (water flow hole 22). As a result, the drainage capacity can be ensured, and therefore, when a large amount of hair or the like is accumulated in the lower portion 23a having the smaller mesh of the water passage 23 as described above, it is possible to prevent the drainage capacity from being significantly lowered. In addition, the size of the mesh formed in the entire water passage 23 may be gradually decreased from the upper end of the water passage 23 (the upper end of the upper portion 23b) downward, or the water passage portion. Even if the size of the mesh in the lower portion 23a of the 23 is made constant, the size of the mesh in the upper portion 23b is made constant, and the mesh of the lower portion 23a of the water passage 23 is larger than the mesh of the upper portion 23b. Be good.

  Further, in this example, all of the water flow portion 23 is positioned below the water surface of the pool water 25 in the trap portion 19, but most of the water flow portion 23 except for the upper end portion is stored in the trap portion 19. It may be positioned below the water surface of 25.
