The hair catcher is formed in an R shape, and has an upper edge collar portion in contact with the drainage port and a rib portion for collecting hair contained in the drainage, and an upper end of the rib portion flows into the drainage port. A hair catcher mounting structure is provided in which an upper edge collar portion of the hair catcher is mounted at a position where the drainage becomes a vortex.

  ADVANTAGE OF THE INVENTION According to this invention, the hair catcher attachment structure which makes it easy to remove hair, dust, and lint at the time of collection of hair, dust, and lint is provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Drawing 1 is a mimetic diagram for explaining the hair catcher attachment structure concerning a first embodiment of the present invention. FIG. 2 is a cross-sectional view of the hair catcher mounting structure in FIG.

  As shown in FIGS. 1 and 2, a drainage port 4 through which drainage flows is formed at the bottom of the basin 1, and the drainage port 4 is provided with a hair catcher 31 that collects hair, dust, lint, and the like. . On top of the hair catcher 31, a drain plug 21 for closing the drain port is provided so as to be movable up and down.

This basin 1 is made by integral molding with resin, and the inlet of the drainage port 4 of the basin 1 has no flange and has a convex R shape. The upper edge brim part 33 of the hair catcher 31 is formed in a concave R shape on the outside, and is attached to the convex R part 41 of the drain outlet. By being attached in this way, there is no gap between the upper edge flange portion 33 of the hair catcher 31 and the convex R portion 41 of the drainage port, so that it fits well, and hair, dust, lint etc. are on the rib portion 32 side of the hair catcher 31 Will be guided to.
Although the washbasin 1 is made of resin, it is sufficient that the entrance of the drainage port is formed in a convex R shape even if it is made of earthenware.

FIG. 3 shows the hair catcher 31. a) shows a view from above, and b) shows a sectional view.
The hair catcher is formed with a plurality of gently arcuate ribs 32a downward from the upper edge collar 33 toward the center to constitute the rib 32. Between the rib 32a and the rib 32a, there is a bottom portion 37 in which a plurality of water passage holes 36 are formed.

The drainage containing hair and the like flows from the bottom of the basin to the drain 4 and from the convex R part 41 at the entrance of the drain 4 through the upper edge flange 33 of the hair catcher 31 attached to the convex R part 41, The drainage drains from the water passage hole 36.
At this time, the drainage forms a pool of water at the bottom 37 of the temporary hair catcher, and the hair contained in the drainage is transmitted through the pool of water and collected across the plurality of ribs 32a. The more hair collected across the plurality of ribs 32a, the easier it is to discard.

  The pool of water varies depending on the size and number of drain holes formed at the bottom of the hair catcher 31, but in order for the hair to be collected across the plurality of ribs 32 a, the drainage is discharged from the drain port 4 to the hair catcher 31. The influence of the angle when flowing in is great. That is, the state of collection varies depending on the height attached to the drainage port convex R portion 41 of the upper edge brim portion 33 of the hair catcher.

As a first embodiment of the present invention, the outer shape of the hair catcher is Φ60 mm, the difference between the upper edge collar and the rib upper end is 7 mm, and the total area of the water passage holes is 880 mm ² . (Area ratio: about 30%) Using this hair catcher, the height of the attachment to the convex R portion of the drainage port was changed to evaluate the state of collection.

Description of Evaluation Test 1 <Test 1>
In the present invention, the mounting position (height) of the hair catcher was changed, and the tracer flowed to the drainage instead of the hair, and the collection status of the tracer by the hair catcher was evaluated. The results are shown in Table 1.
As shown in FIG. 4, the attachment position is represented by an angle formed by the direction (tangent) of the drainage flow and the horizontal with respect to the convexity R of the drainage port.
The upper edge of the hair catcher was attached.

試験Ｎｏ．１では、髪の毛の一部がヘアキャッチャーの上端から洗面器側にはみ出すものが見られた。
試験Ｎｏ．２から４では、図５に示すように、髪の毛の多くがリブの上端に捕集できた。
試験Ｎｏ．５では、捕集した髪の毛が多数リブにぶらさがるように捕集された。

Test No. In No. 1, some of the hair protruded from the upper end of the hair catcher to the basin side.
Test No. From 2 to 4, as shown in FIG. 5, most of the hair could be collected at the upper end of the rib.
Test No. In 5, the collected hair was collected so as to hang on the ribs.

No. The reason why a part of the hair protruded from the upper end of the hair catcher to the basin side was considered to be because the drainage speed was slow and the eddy current was not complete if the tangential angle was shallow. Raru.
No. In Nos. 2 to 4, it was considered that the hair was collected so as to ride on the upper end of the rib because of a complete vortex.
No. In No. 5, it is considered that a large number of collected hairs were collected so as to hang on the ribs because, if the angle in the tangential direction is deep, the drainage speed is high and the water flow is in the vertical direction.

Here, the vortex flow is a state in which the drainage flow that occurs in the vicinity of the drainage port enters the convex R of the drainage port when the drainage tap is opened and water is normally discharged from the faucet.
Usually, vortices occur counterclockwise. A vortex starts to occur when it starts to reach the convex R of the drain outlet, and the speed of drainage increases near the middle of the convex R, which is suitable for the hair catcher to collect the hair on the rib.
On the other hand, in the place connected from the vicinity of the end of the convex R to the drain pipe, the direction of drainage changes to the vertical direction, and the drainage speed increases.

Explanation of Evaluation Test 2 The position of the upper edge of the hair catcher is 60 °, the tracer is run instead of the hair in continuous drainage, the tracer is collected by the hair catcher, and the hair catcher is clogged Was evaluated three times. The results are shown in Table 2.

Description of Evaluation Test 3 A hair catcher was attached at the same position as in Evaluation Test 2, and in this test, how much the hair catcher could be collected was evaluated three times with respect to drainage from a full water state.

  In both of the evaluation tests 2 and 3, the tracer collection rate was 80% or more, and in most cases, the collected state was collected at the upper end of the rib, and good results were obtained.

  The attachment position of the hair catcher upper edge collar is shown as an angle, but when the convex R is about 10 mm, the height of the upper edge collar is preferably 7 mm to 13 mm from the bottom of the basin.
