Description

  The present invention relates to a hair catcher installed at a drain outlet.

  A hair catcher is installed at a drain outlet provided in a bathroom washroom in order to collect foreign substances such as hair contained in the drainage (for example, Patent Document 1).

  In patent document 1, the hair catcher which provided the partition wall part which protrudes upwards in the eyeplate part for collecting hair etc. is installed in the drain outlet. In this hair catcher, the upper portion of the partition wall portion is a knob, and when cleaning, the knob can be grasped and easily removed from the drain port.

JP 2008-274621 A

  By the way, in some unit baths, there is a type in which a drainage port is formed at the bottom of a concave drainage receiving portion provided on the floor of the washing place, and the drainage port is covered with a lid fitted in the drainage receiving portion. In the case of this type of unit bath, the hair catcher is also installed at the drain.

  However, unit baths are often shallower for apartment houses than for detached houses, and the depth of the hair catcher installed at the outlet (from the outlet) In many cases, there is a limit to the amount of protrusion).

For this reason, when the partition wall part which protrudes upwards like the hair catcher of patent document 1 is provided, the problem that a lid | cover and a partition wall part interfere and a lid | cover cannot be closed arises. There is a fear.
In consideration of the above problem, if the amount of protrusion of the partition wall portion from the eye plate portion is reduced, the wastewater flowing into the drainage receiving portion from the washing place easily gets over the partition wall portion. As described above, when the drainage is repeatedly passed over the partition wall, the knob is contaminated with the drainage, or the hair is attached to the knob and becomes dirty.

  This invention makes it a subject to suppress the dirt of the knob | pick part picked at the time of attachment / detachment operation to a drain outlet, even if there is height restriction in an installation space.

  The hair catcher according to claim 1, wherein the hair catcher body is detachably attached to a drain outlet provided in the washing place, and is formed on the washing place side of the hair catcher body, and has a concave shape into which drainage flows from the washing place. A first inflow portion, a concave second inflow portion formed on a bottom surface of the first inflow portion, and formed with a first drainage hole through which the drainage flowing from the first inflow portion flows out into the drainage port; Provided on the bottom surface of the first inflow portion and between the side wall surface of the first inflow portion and the second inflow portion, protrudes toward the washing area, and a part of the hair catcher body is attached to and detached from the drain port. The drainage which is formed between the wall portion constituting the knob portion to be picked and the bottom surface of the first inflow portion and at least between the wall portion and the side wall surface of the first inflow portion, and flows in from the washing place Spilled into the drain It has a second drain hole that, the.

In the hair catcher according to the first aspect, the waste water from the washing place flows into the first inflow portion, and flows out into the drain through the second drain hole. Further, the wastewater that cannot be treated in the second drainage hole flows from the first inflow portion into the second inflow portion, and flows out into the drainage port through the first drainage hole.
Here, when the foreign material (for example, hair etc.) is mixed in the waste_water | drain from a washing place, this foreign material flows into a 2nd inflow part from a 1st inflow part with a waste_water | drain. And since the waste_water | drain which flowed into the 2nd inflow part flows out into a drain outlet through a 1st drain hole, a foreign material remains in a 2nd inflow part. That is, the foreign matter is collected by the second inflow portion.
The hair catcher body is detached from the drain port by picking the knob and performing an operation of detaching the hair catcher body from the drain port. And the drainage performance of a hair catcher recovers by removing a foreign material from the 2nd inflow part.

  In the hair catcher, since the wall portion protruding toward the washing area is provided on the bottom surface of the first inflow portion, for example, compared with the wall portion protruding toward the washing area on the surface of the hair catcher body on the washing area side. Thus, the amount of protrusion of the wall portion from the hair catcher body is reduced, and the installation is possible even if the height of the installation space of the hair catcher is limited.

  On the other hand, in the hair catcher, by increasing the depth of the first inflow portion, the protrusion height of the wall portion from the bottom surface of the first inflow portion can be increased without increasing the amount of protrusion of the wall portion from the hair catcher body. The height can be increased. Thereby, the climbing of the wall part of the waste_water | drain which flows into a 1st inflow part from a washing place can be suppressed.

Moreover, in the said hair catcher, since the 2nd drainage hole is formed in the bottom face of the 1st inflow part and at least between the wall part and the side wall surface of the 1st inflow part, it flows into the 1st inflow part from the washing place. The drained water flows out into the drainage port through the second drainage hole before the wall part (between the wall part and the side wall surface of the first inflow part). In the hair catcher, for example, compared to a case in which the second drainage hole is not formed between the wall portion and the side wall surface of the first inflow portion, the drainage to get over the wall portion is second before the wall portion. Since it flows out into the drain through the drain hole, it is possible to further suppress overcoming of the wall.
Thereby, it is suppressed that the knob | pick part comprised by a part of wall part becomes dirty by adhesion | attachment, such as drainage and hair.

  In addition, when the wastewater that has flowed into the first inflow portion from the washing place flows into the second inflow portion from many directions, the wastewater collides with each other and the flow of the wastewater is disturbed. The rate at which water flows out (drainage rate) tends to decrease. For this reason, in the said hair catcher, the wall part is provided between the side wall surface of this 1st inflow part, and the 2nd inflow part at the bottom face of the 1st inflow part. Since the wall prevents the flow of drainage in at least one direction flowing into the second inflow portion, for example, compared with a case where no wall portion is provided between the side wall surface of the first inflow portion and the second inflow portion. The disturbance of the flow of the waste water flowing into the second inflow portion is suppressed, and the decrease in the speed at which the waste water flows out from the first drain hole is suppressed.

  As mentioned above, according to the said hair catcher, even if there is height restriction in installation space, it can install, and the stain | pollution | contamination of the knob | pick part picked at the time of the attachment or detachment operation to a drain port can be suppressed.

  The hair catcher according to claim 2 is the hair catcher according to claim 1, wherein the wall portion extends so as to surround a part of the outer periphery of the second inflow portion along the bottom surface of the first inflow portion. Exist.

  In the hair catcher according to claim 2, since the wall portion extends so as to surround a part of the outer periphery of the second inflow portion along the bottom surface of the first inflow portion, the wall portion flows into the second inflow portion. For example, the wall portion is not extended so as to surround a part of the outer periphery of the second inflow portion, so that the drainage water flowing into the second inflow portion is prevented. Flow disturbance is further suppressed.

  The hair catcher according to claim 3 is the hair catcher according to claim 2, wherein the outer wall surface of the wall portion opposite to the second inflow portion side surrounds the outer periphery of the second inflow portion. Is so curved.

  In the hair catcher according to claim 3, since the outer wall surface of the wall portion is curved so as to surround the second inflow portion, the drainage that has flowed into the first inflow portion from the washing area along the curved outer wall surface. And smoothly guided to the end of the wall in the extending direction. Thereby, for example, compared with the case where the outer wall surface of the wall portion extends linearly without surrounding the outer periphery of the second inflow portion, the wall portion of the drainage that has flowed into the first inflow portion from the washing place has been overcome. Can be suppressed.

  The hair catcher according to claim 4 is the hair catcher according to claim 3, wherein the second inflow portion is circular in cross section when viewed from the washing area side, and the outer wall surface of the wall portion is the wall portion. Are bent so that both end sides in the extending direction face the center of the second inflow portion.

  In the hair catcher according to claim 4, since both end sides in the wall portion extending direction of the outer wall surface are curved so as to face the center of the second inflow portion, the wastewater that has flowed into the first inflow portion from the washing place Is smoothly guided to the second inflow portion on both end sides in the wall extending direction along the curved outer wall surface. Accordingly, for example, both end sides of the outer wall surface in the wall extending direction are not curved so as to face the center of the second inflow portion (for example, both end sides of the outer wall surface in the wall extending direction are second Compared to the shape along the side wall surface of the inflow portion), the wastewater that has flowed into the first inflow portion from the washing place can be smoothly guided to the second inflow portion.

  The hair catcher according to claim 5 is the hair catcher according to any one of claims 1 to 4, wherein the distance from the side wall surface of the first inflow portion to the side wall surface of the second inflow portion is It is shorter in other areas than the area where the wall is provided.

  In the hair catcher according to claim 5, since the distance from the side wall surface of the first inflow portion to the side wall surface of the second inflow portion is shorter in the other region than the region in which the wall portion is provided, the other region side The wastewater flowing through the second portion flows into the second inflow portion faster than the region where the wall portion is provided, and flows out into the drainage port through the first drainage hole. With this configuration, the waste water flowing from the washing place into the first inflow portion smoothly flows into the second inflow portion and is processed (out into the drain port). Thereby, even if a large amount of waste water flows into the first inflow portion suddenly from the washing place, it is possible to prevent the drainage from overflowing from the first inflow portion.

  As described above, according to the hair catcher of the present invention, it can be installed even if there is a height restriction on the installation space, and it is possible to suppress dirt on the knob portion picked during the attachment / detachment operation to the drain port. it can.

  As shown in FIG. 1, the bathroom 90 includes a washing place 92 and a bathtub 94. On the floor surface 92A of the washing place 92, a concave drainage receiving portion 96 is formed in the vicinity of the boundary with the bathtub 94 (see FIGS. 2 and 4).

  The floor surface 92 </ b> A of the washing place 92 is gently inclined so that the height decreases toward the drain receiving part 96. Due to this inclination, the drainage on the floor surface 92 </ b> A flows toward the drainage receiving part 96.

  As shown in FIGS. 2 and 4, a drain port 98 is formed at the bottom 96 </ b> A of the drain receiving part 96. The drainage port 98 is for flowing the wastewater that has flowed into the drainage receiving portion 96 from the washing place 92 into the sewage through a drain pipe (not shown). Further, as described above, the hair catcher 10 is detachably attached to the drain port 98.

  As shown in FIGS. 3 and 4, the drainage receiving portion 96 is provided with a decorative lid 100 for shielding the drainage port 98 and the hair catcher 10 from the washing place 92 and the bathtub 94 (that is, blindfolding).

(Hair catcher)
Next, the hair catcher 10 will be described.
As shown in FIGS. 4 and 5, the hair catcher 10 has a resin-made hair catcher body 12 that is detachably attached to the drain port 98. In the present embodiment, the hair catcher main body 12 is made of a resin material. However, any material other than the resin material may be used as long as it is a material that does not easily rust.

  The hair catcher body 12 has a bottomed cylindrical shape in which one end in the axial direction X (direction along the axial center X) is opened and the other end is closed. In the state where the hair catcher main body 12 is attached to the drainage port 98, the axial direction X coincides with the vertical direction of the bathroom, and one end side of the axial direction X is the washing room 92 side. Moreover, the axial center of the hair catcher main body 12 is an axial center of the cylinder part 14 mentioned later.

As shown in FIG. 5, the hair catcher main body 12 includes a cylindrical portion 14 that constitutes one end side in the axial direction X, and a cylindrical portion that constitutes the other end side in the axial direction X and has an outer diameter and an inner diameter smaller than the cylindrical portion 14. 16.
Further, the hair catcher body 12 projects from one end portion in the axial direction X of the cylindrical portion 16 to the outer peripheral side (a direction orthogonal to the axial direction X), and the outer peripheral edge portion is connected to the other end portion in the axial direction X of the cylindrical portion 14. And a bottom portion 20 that closes the other end portion of the cylindrical portion 16 in the axial direction X.

With the above configuration, the hair catcher body 12 is formed with the concave first inflow portion 22 that is recessed on the opposite side with respect to the washing place 92 side (one end side in the axial direction X). Specifically, the first inflow portion 22 includes an inner peripheral wall surface of the cylindrical portion 14 and a wall surface on one end side in the axial direction X of the connecting portion 18.
Hereinafter, the inner peripheral wall surface of the cylindrical portion 14 will be described as the side wall surface 22 </ b> A of the first inflow portion 22, and the wall surface on one end side in the axial direction X of the connecting portion 18 will be described as the bottom surface 22 </ b> B of the first inflow portion 22.

Further, the hair catcher body 12 is formed with a concave second inflow portion 24 that is recessed on the opposite side to the washing place 92 side (one end side in the axial direction X) on the bottom surface 22B of the first inflow portion 22. Specifically, the second inflow portion 24 is configured by an inner peripheral wall surface of the cylindrical portion 16 and a wall surface on one end side in the axial direction X of the bottom portion 20. In addition, the 2nd inflow part 24 is made into circular shape seeing from the washing field 92 side (viewing from the one end side of an axial direction).
Hereinafter, the inner peripheral wall surface of the cylindrical portion 16 will be described as the side wall surface 24 </ b> A of the second inflow portion 24, and the wall surface on one end side in the axial direction X of the bottom portion 20 will be described as the bottom surface 24 </ b> B of the second inflow portion 24.

  As shown in FIG. 2, the waste water from the washing place 92 flows into the first inflow portion 22 and the second inflow portion 24. For this reason, each of the first inflow portion 22 and the second inflow portion 24 has a plurality of drain holes for drainage (details will be described later).

  As shown in FIGS. 5 and 6, the bottom surface 24 </ b> B of the second inflow portion 24 is formed with a plurality of first drain holes 26 through which drain water flowing from the first inflow portion 22 flows out into the drain port 98. The first drain hole 26 is a through hole that penetrates the bottom portion 20 from one end side (washing station 92 side) in the axial direction X to the other end side (the back side of the drain port 98). It is a round hole. In other embodiments of the present invention, the cross-sectional shape of the first drain hole 26 may be an ellipse or a polygon.

  In this embodiment, the drain hole for drainage is not formed on the side wall surface 24A of the second inflow portion 24. However, the present invention is not limited to this configuration, and the drain hole is formed on the side wall surface 24A. Also good.

  As shown in FIGS. 2 and 5, the bottom surface 22 </ b> B of the first inflow portion 22 is formed with a wall portion 28 that protrudes toward one end side in the axial direction X (washing station 92 side). The wall portion 28 is disposed between the side wall surface 22 </ b> A of the first inflow portion 22 and the second inflow portion 24.

  As shown in FIGS. 5 and 6, the wall portion 28 extends along the bottom surface 22 </ b> B of the first inflow portion 22 so as to surround a part of the outer periphery of the second inflow portion 24. The wall portion 28 preferably extends so as to surround 1/8 to 1/2 of the outer periphery of the second inflow portion 24. In addition, when the enclosure of the wall part 28 with respect to the 2nd inflow part 24 is less than 1/8, the effect obtained by obstructing the waste_water | drain which flows into the 1st inflow part 22 vigorously from the washing place 92 of the wall part 28 mentioned later. However, when the ratio exceeds 1/2, the waste water in the first inflow portion 22 hardly flows into the second inflow portion 24. For this reason, in this embodiment, the wall part 28 is extended so that 1 / 8-1 / 2 of the outer periphery of the 2nd inflow part 24 may be enclosed.

  The wall portion 28 is curved so that the outer wall surface 28 </ b> A opposite to the second inflow portion 24 surrounds the outer periphery of the second inflow portion 24. The wall portion 28 is curved so that both ends of the extending direction of the wall portion 28 (hereinafter simply referred to as “wall extending direction”) face the center of the second inflow portion 24. Accordingly, both end sides of the outer wall surface 28 </ b> A in the wall portion extending direction are curved so as to face the center of the second inflow portion 24.

  As shown in FIG. 5, the bottom surface 22 </ b> B of the first inflow portion 22 is linear or curved toward the second inflow portion 24 so that drainage in the first inflow portion 22 can easily flow to the second inflow portion 24. While tilting.

  In addition, a second drain hole 30 is formed in the bottom surface 22 </ b> B of the first inflow portion 22 to allow drainage flowing from the washing place 92 to flow into the drain outlet 98. The second drainage hole 30 is a through-hole penetrating the connecting portion 18 from one end side (washing station 92 side) in the axial direction X to the other end side (the back side of the drainage port 98). Is a round hole. In other embodiments of the present invention, the cross-sectional shape of the second drain hole 30 may be an ellipse or a polygon.

  As shown in FIG. 6, a plurality of second drain holes 30 are arranged between at least the wall portion 28 and the side wall surface 22 </ b> A of the first inflow portion 22. In the present embodiment, the second drain hole 30 is formed in an annular shape on the bottom surface 22B of the first inflow portion 22.

  As shown in FIG. 5, among the bottom surface 22 </ b> B of the first inflow portion 22, the bottom surface 22 </ b> C between the wall portion 28 and the second inflow portion 24 extends from the end of the side wall surface 24 </ b> A of the second inflow portion 24 to the wall portion. It extends to the vicinity of the top of 28, and the upper end is at a position higher than the bottom surface 22B. For this reason, the protruding height from the bottom surface 22C of the inner wall surface 28B (the wall surface opposite to the outer wall surface 28A) is lower in the wall portion 28 than the protruding height from the bottom surface 22B of the outer wall surface 28A. As shown in FIGS. 5 and 6, the bottom surface 22 </ b> C is formed with a recess 32 that is recessed toward the other end side in the axial direction X on the wall 28 side and in the vicinity of the central portion in the wall extending direction. . Thereby, the said center part of the wall part 28 can be picked now as the pick part 34 at the time of attaching / detaching operation of the hair catcher main body to the drain port 98. FIG. As shown in FIG. 6, a plurality of second drain holes 30 are also formed on the bottom surface 22C.

  A third drain hole 36 is also formed in the bottom surface 32 </ b> A of the recess 32 for draining the drain water flowing from the washing place 92 into the drain port 98. The third drain hole 36 is a through hole that penetrates the connecting portion 18 from one end side (washing station 92 side) in the axial direction X to the other end side (the back side of the drain port 98). Is a round hole. In other embodiments of the present invention, the cross-sectional shape of the third drain hole 36 may be an ellipse or a polygon.

  Further, as shown in FIG. 6, the distance from the side wall surface 22A of the first inflow portion 22 to the side wall surface 24A of the second inflow portion 24 (the distance along the direction orthogonal to the axial direction X) is the wall portion. The area M2 is shorter than the area M1 in which 28 is provided. That is, the axial centers of the cylindrical portion 14 and the cylindrical portion 16 are shifted in a direction orthogonal to the axial direction X (in other words, the first inflow portion 22 and the second inflow portion 24 are eccentric).

As shown in FIG. 7, one end of the outer peripheral portion of the cylindrical portion 14 opens to the other end side in the axial direction X, extends along the outer periphery of the cylindrical portion 14, and the other end terminates on the outer periphery of the cylindrical portion 14. A plurality of engaging groove portions 38 are formed. As shown in FIG. 4, an engaging protrusion 98 </ b> A formed at the inlet portion of the drain port 98 enters the engaging groove 38 from one end and engages with the engaging groove 38.
Here, the cylindrical portion 14 of the hair catcher main body 12 is inserted into the drainage port 98 so that the engagement protrusion 98A enters the engagement groove 38, and the engagement protrusion 98A is the back (the other end) of the engagement groove 38. By rotating the hair catcher body 12 so as to move to the position, the engagement groove 38 and the engagement protrusion 98 </ b> A are engaged, and the hair catcher body 12 is attached to the drain port 98.

Next, the hair catcher 10 of 1st Embodiment is demonstrated.
In the hair catcher 10, the waste water from the washing place 92 flows into the first inflow portion 22 and flows out into the drain port 98 through the second drain hole 30. Further, the wastewater that cannot be treated in the second drainage hole 30 flows from the first inflow portion 22 into the second inflow portion 24, and flows out into the drainage port 98 through the first drainage hole 26.

  Here, when foreign matter (for example, hair etc.) is mixed in the waste water from the washing place 92, the foreign matter flows into the second inflow portion 24 from the first inflow portion 22 together with the waste water. And since the waste_water | drain which flowed into the 2nd inflow part 24 flows out into the drain outlet 98 through the 1st drain hole 26, a foreign material remains in the 2nd inflow part 24. FIG. That is, the foreign matter is collected by the second inflow portion 24.

  The hair catcher main body 12 is detached from the drainage port 98 by picking the knob 34 and performing an operation of detaching the haircatcher main body 12 from the drainage port 98. And the drainage performance of the hair catcher 10 is recovered by removing foreign matter from the second inflow portion 24.

  In the hair catcher 10, since the wall part 28 is provided in the bottom face 22B of the 1st inflow part 22, the surface of the one end side of the axial direction X of the hair catcher main body 12 (here, one end part of the cylinder part 14), for example Compared with the case where the wall portion 28 is provided, the protruding amount of the wall portion 28 from the hair catcher body 12 is reduced, and the installation is possible even if the installation space of the hair catcher 10 is limited in height. That is, for example, the bathroom 90 of the present embodiment is a unit bath for an apartment house, and the distance between the bottom 96A of the drainage receiving part 96 and the back surface of the decorative lid 100 is narrow (the height of the installation space of the hair catcher 10 is small). In the case of the hair catcher 10, even if it is installed in the drainage port 98, the wall portion 28 and the decorative lid as shown in FIG. 100 can be installed without interference.

  On the other hand, in the hair catcher 10, by increasing the depth of the first inflow portion 22, the amount of protrusion of the wall portion 28 from the hair catcher main body 12 is not increased, and the first inflow portion 22 of the wall portion 28 is increased. The protruding height from the bottom surface 22B can be increased. As a result, it is possible to suppress the drainage wall portion 28 from flowing into the first inflow portion 22 from the washing place 92.

In the hair catcher 10, the second drainage hole 30 is formed on the bottom surface 22 </ b> B of the first inflow portion 22 and between the wall portion 28 and the side wall surface 22 </ b> A of the first inflow portion 22. The drainage that has flowed into the first inflow portion 22 flows out into the drainage port 98 through the second drainage hole 30 in front of the wall portion 28 (between the wall portion 28 and the side wall surface 22A of the first inflow portion 22). In the hair catcher 10, for example, compared to the case where the second drainage hole 30 is not formed between the wall portion 28 and the side wall surface 22A of the first inflow portion 22, the drainage that tries to get over the wall portion 28 is a wall. Since it flows out into the drainage port 98 through the second drainage hole 30 before the portion 28, it is possible to further suppress the climbing over the wall portion 28.
Thereby, it is suppressed that the knob | pick part 34 comprised by the wall part 28 becomes dirty by adhesion | attachment, such as drainage and hair.

  In addition, when the waste water flowing into the first inflow portion 22 from the washing place 92 flows into the second inflow portion 24 from many directions, the waste water collides with each other to disturb the flow, and the first drain hole of the second inflow portion 24. The speed (drainage speed) at which the drainage flows out from 26 tends to decrease. Therefore, in the hair catcher 10, the wall portion 28 is provided between the side wall surface 22 </ b> A of the first inflow portion 22 and the second inflow portion 24. Since the wall portion 28 prevents the flow of drainage in at least one direction flowing into the second inflow portion 24, for example, the wall portion 28 is provided between the side wall surface 22A of the first inflow portion 22 and the second inflow portion 24. Compared with those not provided, the disturbance of the drainage flowing into the second inflow portion 24 is suppressed, and the decrease in the rate at which the drainage flows out from the first drainage hole 26 is suppressed.

  In particular, since the wall portion 28 extends along the bottom surface 22B of the first inflow portion 22 so as to surround a part of the outer periphery of the second inflow portion 24, the drainage flowing into the second inflow portion 24 is reduced. Since the flow is hindered in a wide range, for example, the wall portion 28 is not extended so as to surround a part of the outer periphery of the second inflow portion 24, and the wastewater flowing into the second inflow portion 24 is reduced. Disturbance is further suppressed.

  Further, since the outer wall surface 28A of the wall portion 28 is curved so as to surround the outer periphery of the second inflow portion 24, the drainage that has flowed into the first inflow portion 22 from the washing place 92 along the curved outer wall surface 28A. The wall portion 28 is smoothly guided to the end portion of the wall portion 28 in the extending direction. Thereby, for example, compared with the case where the outer wall surface 28 </ b> A of the wall portion 28 extends linearly without surrounding the outer periphery of the second inflow portion 24, Overcoming the wall portion 28 can be suppressed.

  Further, since both end sides of the outer wall surface 28A in the extending direction of the wall portion are curved so as to face the center of the second inflow portion 24, the drainage flowing from the washing place 92 into the first inflow portion 22 is curved. It is smoothly guided along the wall surface 28A to the second inflow portion 24 on the end side in the wall portion extending direction. Accordingly, for example, both end sides of the outer wall surface 28A in the wall portion extending direction are not curved so as to face the center of the second inflow portion 24 (for example, both end sides of the outer wall surface 28A in the wall portion extending direction) Compared to the shape of the second inflow portion 24 along the side wall surface 24 </ b> A), the wastewater flowing into the first inflow portion 22 from the washing place 92 can be smoothly guided to the second inflow portion 24.

  Moreover, in the said hair catcher 10, since the distance from the side wall surface 22A of the 1st inflow part 22 to the side wall surface 24A of the 2nd inflow part 24 is short in the area | region M2 other than the area | region M1 in which the wall part 28 was provided. The drainage flowing through the other region M2 flows into the second inflow portion 24 faster than the drainage flowing through the region M1, and flows out into the drainage port 98 through the first drainage hole 26. With this configuration, the waste water flowing from the washing place 92 to the first inflow portion 22 smoothly flows into the second inflow portion 24 and is processed (out into the drain port). Thereby, even if a large amount of waste water flows into the 1st inflow part 22 suddenly from the washing place 92, it can suppress that a waste water overflows from the 1st inflow part 22.

  On the other hand, in the said hair catcher 10, since the hollow 32 is formed in the bottom face 22C vicinity of the center part (pick part 34) of the wall part extension direction of the wall part 28, it is easy to pick the pick part 34. FIG. Since the third drain hole 36 is also formed in the bottom surface 32 </ b> A of the recess 32, for example, even when the drainage overflows from the second inflow portion 24, the drainage flows through the third drain hole 36 of the recess 32. It flows out into the drainage port 98 through. For this reason, the hair catcher 10 suppresses the drainage from the second inflow portion 24 side from getting over the wall portion 28 as compared with, for example, a configuration in which the third drainage hole 36 is not formed in the bottom surface 32A of the recess 32. it can.
