Description

  The present invention relates to a hair catcher that collects hair, dust, and the like, and more particularly, to a hair catcher technique that can suitably clean collected hair, dust, and the like.

  Conventionally, a hair catcher has been used to collect hair, dust, and the like in drainage flowing through a drain pipe. The hair catcher is often used together with a drain plug in a drain pipe, for example. Such a hair catcher is inserted through a drain outlet of a bathroom vanity, etc., installed in the drain pipe, and when the drain plug is opened, removes hair, dirt, etc. contained in the drainage flowing from the drain outlet into the drain pipe. Can be collected.

  For example, Patent Document 1 discloses a hair catcher formed of a soft material, and an axial core portion formed so as to be positioned substantially in the center along the flow direction of drainage in a drain pipe, and the axial core portion. A V-shaped heap consisting of a first collecting rib that extends downward in a substantially conical shape and a second collecting rib that extends continuously upward from the tip of the first collecting rib. An arc catcher has been proposed.

  Further, Patent Document 2 is a hair catcher that is provided in a drain plug device whose drain opening is opened and closed by remote control and has a net part, and the net part has a plurality of ribs having a mountain-shaped cross section extending radially. A hair catcher in which a plurality of holes are formed between the ribs has been proposed.

JP 2009-79368 A JP 2010-37923 A

  However, in the case of the hair catcher according to Patent Document 1, hair, dust, and the like contained in the drainage are collected at the V-shaped bottom. At the time of cleaning, the tip of the second collecting rib made of a soft material is deformed so as to face downward, and the collected hair and dust must be removed from the hair catcher, and the cleaning work is complicated. It was a thing.

  Furthermore, in the case of the hair catcher which concerns on patent document 2, the hair contained in waste_water | drain catches on this rib by providing several rib of cross-sectional mountain shape, and can collect hair suitably. However, at the time of cleaning, due to the shape of the rib described above, the hair caught on the rib may not be easily removed.

  This invention is made | formed in view of such a point, The place made into the objective is to provide the hair catcher which can remove the collected hair and dust easily.

  In view of the above-described problems, the hair catcher according to the present invention is a hair catcher that is disposed in a drain pipe and collects dust and hair in the drainage, and the hair catcher has a flow direction of drainage in the drain pipe. And a spindle extending so as to incline downward from the outer peripheral surface near the upper end of the shaft core toward the inner wall of the drainage pipe. An inclined horizontal wall portion, an annular horizontal wall portion extending in a horizontal direction from an outer peripheral lower end portion of the inclined wall portion, and from an outer peripheral end portion of the horizontal wall portion toward an upper side to an inner wall of the drain pipe An annular outer peripheral wall portion extending so as to extend along the inclined wall portion, and a plurality of first drainage holes having a curved opening edge are formed in the inclined wall portion, and the horizontal wall portion Are formed with a plurality of second drainage holes having a curved opening edge. And wherein the door.

  According to the present invention, since the plurality of first drainage holes are formed in the inclined wall portion and the plurality of second drainage holes are formed in the horizontal wall portion, the first drainage hole and the second drainage hole are formed. The drainage is allowed to flow through the drainage holes, and hair and dust can be collected by the inclined wall portion and the horizontal wall portion.

  In addition, since the inclined wall portion is inclined downward, a part of the drainage flowing toward the inclined wall portion flows into the first drainage hole, and the remaining drainage is inclined wall portion. It is also possible to flow down toward the horizontal wall portion and flow the remaining drainage into the second drainage hole formed in the horizontal wall portion.

  Moreover, since the horizontal wall part of the hair catcher was extended in the horizontal direction from the outer periphery lower end part of the inclined wall part, the operator was formed by the inclined wall part, the horizontal wall part, and the outer peripheral wall part at the time of cleaning. A finger can be easily put into the space, and the collected hair can be easily removed. Furthermore, since the opening edge of the first and second drainage holes has a curved shape, the hair caught in the first and second drainage holes can be easily removed.

  In addition, the opening edge referred to in the present invention is a curved shape, and can include a circular shape, an elliptical shape, an oval shape, a long hole shape connecting a pair of straight lines and a semicircle, a triangle, a rectangle, Or the thing of the shape where a straight line does not cross | intersect like a polygon.

  Furthermore, as a preferable aspect, a locking portion for positioning to be locked to the inner wall of the drain pipe is formed on the lower end side of the shaft core portion, and the locking portion is connected to the inner wall of the drain pipe. In a locked state, an extension line along the inclined surface of the drain outlet inclined toward the inside of the drain pipe is formed at a position that intersects the inclined wall portion.

  According to this aspect, the water flowing along the inclined surface of the drain port can be directed to the inclined wall portion of the hair catcher. Thereby, while flowing a part of drainage to the 1st drainage hole formed in the inclined wall part, the remaining drainage is poured from the inclined wall part to the horizontal wall part, and the 2nd drainage formed in the horizontal wall part It can be drained through a hole. Such a flow of drainage makes it easy for hair contained in the drainage to be collected around the horizontal wall portion and the outer peripheral wall portion with almost no hair caught in the first and second drainage holes. Thereby, while ensuring the drainability of the 1st and 2nd drainage hole, the collected hair can be easily removed from the hair catcher.

  In addition, the first and second drainage holes formed in the hair catcher can drain the drainage and can easily collect the hair in the drainage. Is not particularly limited.

  However, as a more preferable aspect, the opening area ratio of the plurality of first drainage holes with respect to the surface area of the inclined wall portion is the opening area ratio of the plurality of second drainage holes with respect to the surface area of the horizontal wall portion. Smaller than.

  According to this aspect, since the opening area rate of the plurality of first drainage holes in the inclined wall portion is made smaller than the opening area rate of the plurality of second drainage holes, the inclined wall portion is changed to the horizontal wall portion. The drainage easily flows, and as a result, the hair contained in the drainage is easily collected around the horizontal wall portion and the outer peripheral wall portion.

  On the premise of such an aspect, it is more preferable that the opening area ratio of the first drainage hole is in a range of 45% to 65%. By setting the opening area ratio of the first drainage hole in such a range, drainage can be more easily flowed from the inclined wall portion to the horizontal wall portion.

  Here, when the opening area ratio exceeds 65%, in the inclined wall portion, most drainage flows into the first drainage hole, and hair or the like may be easily caught in the first drainage hole. . On the other hand, when the opening area ratio is less than 45%, most of the drainage flows from the inclined wall portion toward the horizontal wall portion. Thereby, since the 2nd drainage hole of a horizontal wall part bears the drainage, there exists a possibility that the drainage of a hair catcher may fall.

  Furthermore, as a preferable aspect, a plurality of third drainage holes whose opening edges are curved are further formed so as to straddle the inclined wall portion and the horizontal wall portion. According to the present invention, by providing the third drainage hole in addition to the first and second drainage holes, the drainage of the hair catcher can be further enhanced.

  As another preferred embodiment, either one or both of the first drainage hole and the second drainage hole may be formed so as to straddle the inclined wall portion and the horizontal wall portion. Thereby, since at least one of the 1st and 2nd hole for drainage can bear the drainage of the part (an inclination wall surface or a horizontal wall part) of the other side, the drainage property of a hair catcher can further be improved.

  According to the hair catcher according to the present invention, it is possible to collect the hair and dust in the waste water and to easily remove the collected hair and dust.
