Description

  The present invention relates to a hair catcher for a drain plug that is attached to a drain outlet of a bathroom vanity or the like and collects hair and dust, and more particularly, a hair catcher for a drain plug that maintains drainage performance and improves cleanability. Related to technology.

  Conventionally, the description of Patent Document 1 is known regarding the configuration of a drain plug hair catcher including a parasol-type hair catcher. According to Patent Document 1, as shown in FIG. 6, a drain opening 13a is formed at the bottom of the wash bowl 13, and a drain pipe 14 is attached to the drain opening 13a. An opening 15 of the overflow pipe 16 is provided in the middle of the drain pipe 14.

  A drain catch hair catcher 12 is provided on a shaft 2 at a lower end of a disc-shaped kerep 1 for opening and closing a drain opening 13 a at a right angle to the kerep 1, and a hair catcher 11 is attached to the shaft 2 via a tube shaft 10. A weight (not shown) is attached to the lower end of the shaft 2 so as to be slidably inserted.

  The hair catcher 11 includes a cylindrical tubular body 8 having a collection projection 7 on the outer peripheral portion, and collection ribs 5 provided above the tubular body 8 and radially formed between the tubular shaft 10. The radial collecting ribs 5 are formed in a substantially conical shape (parasol type) so that the height gradually decreases from the cylindrical shaft 10 toward the cylindrical body 8. By using the hair catcher 12 for the drain plug, even if hair or dirt flows into the drain port, it is caught by the collecting rib 5 of the hair catcher 11 and collected.

At this time, since the collecting rib 5 spreads obliquely downward in a parasol shape, hair and dust collect below the collecting rib 5, so that the drain opening 4 between the upper collecting ribs 5 is not clogged so much. Therefore, sufficient drainage capacity can be secured without lowering the catch rate of hair and dust.
Japanese Patent No. 3462671

  However, since the hair and dust collected below are deposited on the wall of the drain pipe, there is a problem that when the hair catcher 11 is pulled out and cleaned, deposits on the drain pipe wall cannot be easily removed. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems and to provide a drain catcher hair catcher that prevents deterioration of drainage performance and improves cleanability.

  The invention according to claim 1 is a hair catcher for a drain plug provided with a hair catcher in which a plurality of collecting ribs for hooking hair, dust, etc. are provided radially, wherein the hair catcher has a plurality of collecting ribs downward. It is a V-shaped hair catcher composed of a first collecting rib extending in a substantially conical shape and a second collecting rib extending continuously upward from the tip end portion of the first collecting rib. It is characterized by.

  The invention according to claim 2 is the hair catcher for a drain plug according to claim 1, wherein in addition to the V-shaped hair catcher, a horizontal hair catcher in which a plurality of collecting ribs are formed in a horizontal radial shape is provided. It is characterized by providing.

  According to the first aspect of the present invention, the hair catcher has a plurality of collecting ribs that are continuously raised from a first collecting rib in which the plurality of collecting ribs expand downward in a substantially conical shape and a tip portion of the first collecting rib. Since it is a V-shaped hair catcher composed of the second collecting rib extending in the direction, hair and dust can be easily removed because the hair and dust are collected at the bottom of the V-shape.

  Furthermore, since hair and dust are gathered on the V-shaped bottom, the drainage at the upper ends of the first collection rib and the second collection rib can be kept long and drainage is improved. Furthermore, since there are two drainage openings at the upper ends of the first collection rib and the second collection rib, the possibility of the drainage openings being blocked simultaneously is reduced, so that the drainage performance is improved.

  According to invention of Claim 2, since the drainage opening of the upper end part of the 1st collection rib of a V-shaped hair catcher and the upper end part of a 2nd collection rib can be ensured in two places, possibility that a drainage opening will be blocked simultaneously reduces. Therefore, drainage is improved. For this reason, when the V-shaped hair catcher is provided on the downstream side of the horizontal hair catcher, it is possible to prevent the drainage of the V-shaped hair catcher from flowing backward from the overflow pipe into the bowl.

Below, the 1st Embodiment of this invention is described based on FIG. In addition, about the equivalent part to the water catcher for drain plugs shown in FIG. 6, FIG. 7, the same code | symbol is attached | subjected suitably and demonstrated.
<Configuration of hair catcher for drain plug>

  As shown in FIG. 1, a drain opening 13a is formed at the bottom of the wash bowl 13, and a drain pipe 14 is attached to the drain opening 13a. An opening 15 is provided in the middle of the drain pipe 14, and one end 17 of the overflow pipe 16 is fitted into a sleeve joint 18 formed in the opening 15, and the other end of the overflow pipe (not shown) is a wash bowl. 13 is attached to the overflow opening formed in the upper side wall.

  The drain plug hair catcher 30 of the present invention includes two sets of hair catchers 31 each having a plurality of collecting ribs 32 for hooking hair, dust, and the like radially. One hair catcher 31 is continuously extended upward from a first collecting rib 32a in which a plurality of collecting ribs 32 expands in a substantially conical shape downward and from a tip 33 of the first collecting rib 32a. It is the V-shaped hair catcher 31a which consists of the 2nd collection rib 32b made.

  The other hair catcher 31 is a horizontal hair catcher 31b in which a plurality of collecting ribs 32c are formed in a horizontal radial shape. The V-shaped hair catcher 31 a and the horizontal hair catcher 31 b are connected up and down via a cylindrical shaft 34. (V-shaped hair catcher 31a is arranged at the top.)

  A drain catch hair catcher 30 is provided with a shaft 2 perpendicular to the kerep 1 at the lower end of a disc-shaped kerep 1 for opening and closing the drain opening 13a. The shaft 2 has a V-shaped hair catcher 31a and a horizontal hair catcher. 31b is slidably inserted through the cylindrical shaft 34, and the weight 3 is attached to the lower end portion of the shaft 2. 1 is in a state in which the drain stopper hair catcher 30 is inserted into the drain pipe 14, and the kerep 1 is lifted to open the drain opening 13a.

"Detailed structure of hair catcher 31"
As shown in FIGS. 2, 3, and 4, the shape of the V-shaped hair catcher 31a is between the ring 42 and the cylinder shaft 34 having an outer diameter G = 35 mm, a horizontal width Q5 = 1, 5 mm, and a thickness Q2 = mm. The first collecting ribs 32a and the second collecting ribs 32b are formed to be radially connected every angle θ1 = 30 degrees. The first collecting rib 32a has a thickness Q1 = 1, 5 mm, a width S1 = 1, 5 mm, and an angle α = 40 degrees, and the second collecting rib 32b has a thickness Q6 = 1, 0 mm, a width S1 = 1, The first collecting rib 32a and the second collecting rib 32b are formed in a V shape at 5 mm and an angle β = 90 degrees. The V-shaped bottom portion becomes the collecting portion 44.

  The shape of the horizontal hair catcher 31b is as follows: a ring 40 having an outer diameter G = 35 mm, a width Q3 = 1, 5 mm, a thickness Q4 = 1, 5 mm, and a ring S 40 having a thickness S2 = 1, 5 mm. The ribs 32c are radially connected every angle θ2 = 45 degrees to form the drainage openings 45. The upper surface of the collecting rib 32c is formed so as to gradually increase in thickness from the ring 40 toward the cylindrical shaft 34 with an inclination of θ3 = 10 degrees.

  The cylinder shaft 34 has a height H = 40 mm, an outer diameter G2 = 11 mm, and an inner diameter G3 = 8 mm. The bottom surface of the horizontal hair catcher 31b is aligned with a position P1 having a height H2 = 2 mm from the lower end 34a of the cylinder shaft 34. A horizontal hair catcher 31b is attached. The V-shaped hair catcher 31a is fixed to the vicinity of the upper end portion 34b of the cylindrical shaft 34 so that the outer peripheral upper end portion P2 of the V-shaped hair catcher 31a matches the level of the height H1 = 31 mm from the position P1.

<Operation of hair catcher for drain plug>
Based on FIGS. 1 and 2, the action of the drain catch hair catcher will be described.
When opening the drainage opening 13a, the shaft 2 is first lifted up from the closed drainage opening 13a by a method (not shown) to lift the shaft 2 and the shaft 2 is slightly rotated around the cylinder shaft 34. As a result, the shaft 2 is held by the cylindrical shaft 34 by a structure (not shown), and the Kellep 1 (and the shaft 2) is held so as not to descend.

  The hair catcher 31 and the cylinder shaft 34 are supported by a stopper 19, and when the kerep 1 is lifted, the whole drain catch hair catcher 30 can be detached from the drain opening 13 a. Then, the drainage 20 passes through the drainage opening 13a, passes through the collecting ribs 32a, 32b, and 32c of the V-shaped hair catcher 31a and the horizontal haircatcher 31b and flows out downstream.

  As the usage time elapses, the hair and dust passing through the drain opening 13a adhere to the V-shaped hair catcher 31a, and the hair and dust from the overflow opening (not shown) pass through the overflow pipe 16 and the horizontal hair catcher 31b. Adhere to.

  In the V-shaped hair catcher 31a, hair and dust accumulate around the collecting portion 44, so that the upper ends of the drain openings 45 of the first collecting rib 32a and the second collecting rib 32b are not blocked. Since it can hold | maintain, the waste_water | drain 20 can pass the V-shaped hair catcher 31a as the waste_water | drain 20a, 20b.

  For this reason, since the possibility that the drainage opening 45 is simultaneously blocked can be reduced, the drainage performance is improved. Furthermore, since the drainage is improved, it is difficult for hair and dust to adhere directly to the inner surface of the drainpipe 14, so that the drainage pipe 14 can be cleaned only by cleaning the V-shaped hair catcher 31a.

<Second Embodiment of the Present Invention>
A second embodiment of the present invention will be described with reference to FIG. In addition, about the same component as the drain catch hair catcher shown in FIGS. 1-4, the same code | symbol is attached | subjected to drawing and the overlapping description is abbreviate | omitted.

  As shown in FIG. 5, the drain catch hair catcher 30 has a V-shaped hair catcher 31 a disposed at the bottom and a horizontal hair catcher 31 b disposed at the top via a cylindrical shaft 34.

  As described above, since the V-shaped hair catcher 31a can secure two drainage openings 45 at the upper end portion between the respective collection ribs of the first collection rib 32a and the second collection rib 32b, the drainage opening 45 is provided. At the same time, the possibility of clogging can be reduced, so drainage performance is improved.

  Further, by improving the drainage, it is possible to prevent the drainage of the V-shaped hair catcher 31a from flowing back into the wash bowl 13 through the overflow pipe 16. As mentioned above, although embodiment of this invention was described based on drawing, all said Example shows an example of this invention, and it cannot be overemphasized that this invention should not be limited to these.

  The V-shaped hair catcher 31a and the horizontal-shaped hair catcher 31b may not be used simultaneously, but the V-shaped hair catcher 31a may be used alone. In this case, the horizontal hair catcher 31b is removed in the state shown in FIG. 5. However, since two drainage openings 45 can be secured as described above, the drainage is improved, and the surface is washed through the overflow pipe 16. A phenomenon of backflow into the bowl 13 can be prevented. Although the example which provides the hair catcher in the drain outlet of the wash bowl of a vanity top was demonstrated, it can implement similarly to the drain outlet of a bathtub and the drain outlet of a kitchen.
