Description

本開示は、ヘアキャッチャーに関する。 The present disclosure relates to a hair catcher.

浴室や洗面台の排水口には、排水管に髪の毛や小さなゴミ等が流れて排水管が詰まらないようにするために、ヘアキャッチャーが取り付けられている。ヘアキャッチャーは、髪の毛が絡まったり挟まったりし易いため、清掃及び髪の毛の捕集に手間がかかる。 Hair catchers are attached to the drains of bathrooms and wash basins to prevent hair and small debris from flowing into the drains and clogging the drains. Hair catchers tend to get entangled or pinched, so cleaning and collecting hair is troublesome.

従来、特許文献１には、排水を利用してヘアキャッチャー内に旋回流を発生させることによって、髪の毛をヘアキャッチャー内に纏め、ヘアキャッチャーの清掃及び髪の毛の捕集を容易にする技術が開示されている。このヘアキャッチャーは、底部の中心から側面にかけて周方向に多数の孔を穿設してなる底メッシュ部と、底メッシュ部の上方に配置され、孔が形成されていない非メッシュ部と、非メッシュ部の上方に配置され、周方向に多数の孔を穿設してなる中間メッシュ部と、を有し、浴室の洗い場排水口に載置されてセットされる。 Conventionally, Patent Document 1 discloses a technique for gathering hair in a hair catcher by generating a swirling flow in the hair catcher using drainage, facilitating cleaning of the hair catcher and collection of the hair. ing. This hair catcher has a bottom mesh portion formed by drilling a large number of holes in the circumferential direction from the center of the bottom to the side surface, a non-mesh portion arranged above the bottom mesh portion and having no holes formed, and a non-mesh portion. It has an intermediate mesh portion which is arranged above the portion and has a large number of holes formed in the circumferential direction, and is placed and set on the drainage port of the bathroom washing place.

特開２０１１−２３１５０７号公報Japanese Unexamined Patent Publication No. 2011-231507

特許文献１に記載のヘアキャッチャーは、排水口に載置されてセットされるため、排水口に大量の水が流れ込んだ場合には、ヘアキャッチャーが排水口から浮き上がってしまう。ヘアキャッチャーが浮き上がると、旋回流を発生させることができず、髪の毛が散乱して清掃性が悪化する問題がある。 Since the hair catcher described in Patent Document 1 is placed and set on the drain port, the hair catcher floats up from the drain port when a large amount of water flows into the drain port. When the hair catcher floats up, it is not possible to generate a swirling flow, and there is a problem that the hair is scattered and the cleanability is deteriorated.

ヘアキャッチャーの浮き上がりを防止するためには、ヘアキャッチャーの外側面に、排水口に係止するための係止手段を設けることが考えられる。しかし、ヘアキャッチャーの外側面には、水を排水するための多数の開口が設けられるため、ヘアキャッチャーの外側面に係止手段を設けると、係止手段が開口を塞いでしまい、排水性能に影響を与える問題がある。 In order to prevent the hair catcher from rising, it is conceivable to provide a locking means for locking to the drain port on the outer surface of the hair catcher. However, since the outer surface of the hair catcher is provided with a large number of openings for draining water, if the locking means is provided on the outer surface of the hair catcher, the locking means closes the openings, resulting in drainage performance. There are issues that affect it.

したがって、排水性能に影響を与えることなく、ヘアキャッチャーの排水口からの浮き上がりを防止できるようにすることが求められる。 Therefore, it is required to be able to prevent the hair catcher from rising from the drain port without affecting the drainage performance.

本開示に係るヘアキャッチャーは、上縁部と、底部に配置される貯水部と、前記上縁部と前記貯水部との間に配置され、内部に流入した水の一部を外部へ排水する複数の開口を有する排水部と、前記上縁部と前記貯水部との間を繋ぐように配置され、前記上縁部から流入した水の一部を前記貯水部に向けて導く導水部と、前記導水部の外面に配置され、排水口の内周面に設けられる係合突部に係合する係合凹部と、を有する。 The hair catcher according to the present disclosure is arranged between the upper edge portion, the water storage portion arranged at the bottom, and the upper edge portion and the water storage portion, and drains a part of the water that has flowed into the inside to the outside. A drainage section having a plurality of openings, a water guiding section which is arranged so as to connect between the upper edge portion and the water storage section, and guides a part of the water flowing in from the upper edge portion toward the water storage section. It has an engaging recess that is arranged on the outer surface of the water guiding portion and engages with an engaging protrusion provided on the inner peripheral surface of the drainage port.

It has a connection pipe 204 for connecting the drain trap portion 201 and the tub drain port 202, and a drain pipe 205 for draining the water in the drain trap portion 201. The drainage FL from the bathtub drainage port 202 flows into the drainage trap portion 201 through the connection pipe 204 as shown in FIG. The washing place drainage port 203 opens to the washing place floor 100 and opens to the upper part of the drainage trap portion 201. In FIG. 1, the bathtub provided adjacent to the washing floor 100 is not shown.

図２に示すように、洗い場排水口２０３の内周面は複数の係合突部２０３ａを有する。係合突部２０３ａは、ヘアキャッチャー１の外周面に設けられる後述の係合凹部６と係合することによって、ヘアキャッチャー１を洗い場排水口２０３に固定する部位である。これによって、洗い場排水口２０３に大量の水が流れ込んでも、ヘアキャッチャー１が洗い場排水口２０３から浮き上がることはない。本実施形態の洗い場排水口２０３の内周面には、４つの係合突部２０３ａが９０°の角度で離れて配置されている。しかし、洗い場排水口２０３の内周面には、後述の２つの係合凹部６，６と係合する少なくとも２つの係合突部２０３ａが設けられていればよい。 As shown in FIG. 2, the inner peripheral surface of the washing place drainage port 203 has a plurality of engaging protrusions 203a. The engaging protrusion 203a is a portion for fixing the hair catcher 1 to the washing place drain port 203 by engaging with an engaging recess 6 provided on the outer peripheral surface of the hair catcher 1. As a result, even if a large amount of water flows into the washing place drainage port 203, the hair catcher 1 does not float from the washing place drainage port 203. Four engaging protrusions 203a are arranged at an angle of 90 ° on the inner peripheral surface of the washing place drainage port 203 of the present embodiment. However, at least two engaging protrusions 203a that engage with the two engaging recesses 6 and 6 described later may be provided on the inner peripheral surface of the washing place drainage port 203.

ヘアキャッチャー１は、図３、図４及び図５に示すように、ヘアキャッチャー１の上部に配置される上縁部２と、ヘアキャッチャー１の底部に配置される貯水部３と、上縁部２と貯水部３との間に配置される排水部４と、上縁部２と貯水部３の間を繋ぐように設けられる導水部５と、洗い場排水口２０３の係合突部２０３ａと係合する係合凹部６と、を一体に備える樹脂成型品である。ヘアキャッチャー１は、上縁部２から貯水部３に向けて次第に縮径するすり鉢状に形成される。 As shown in FIGS. 3, 4 and 5, the hair catcher 1 includes an upper edge portion 2 arranged at the upper part of the hair catcher 1, a water storage portion 3 arranged at the bottom of the hair catcher 1, and an upper edge portion. It is engaged with the drainage part 4 arranged between the water storage part 2 and the water storage part 3, the water guide part 5 provided so as to connect between the upper edge part 2 and the water storage part 3, and the engaging protrusion 203a of the washing place drainage port 203. It is a resin molded product integrally provided with a mating engaging recess 6. The hair catcher 1 is formed in a mortar shape that gradually reduces in diameter from the upper edge portion 2 toward the water storage portion 3.

ヘアキャッチャー１において、図５中の矢印で示すように、ヘアキャッチャー１を平面視した場合のＸ方向をヘアキヤッチャー１の周方向と定義する。ヘアキャッチャー１を平面視した場合に、中央に配置される貯水部３の中心から放射方向に延びる方向をヘアキヤッチャー１の径方向と定義する。 In the hair catcher 1, as shown by the arrow in FIG. 5, the X direction when the hair catcher 1 is viewed in a plane is defined as the circumferential direction of the hair catcher 1. When the hair catcher 1 is viewed in a plan view, the direction extending in the radial direction from the center of the water storage unit 3 arranged at the center is defined as the radial direction of the hair catcher 1.

上縁部２は、所定の幅を有する円環状に形成される。上縁部２は、係合突部２０３ａを除く洗い場排水口２０３の内径と略同一の外径を有し、円形の洗い場排水口２０３の内周面に嵌合する。 The upper edge portion 2 is formed in an annular shape having a predetermined width. The upper edge portion 2 has an outer diameter substantially the same as the inner diameter of the washing place drainage port 203 excluding the engaging protrusion 203a, and fits into the inner peripheral surface of the circular washing place drainage port 203.

上縁部２の上面２ａには、上縁部２の中心に対して回転対称な２つの立壁部２１，２１が設けられている。立壁部２１，２１は、それぞれ上縁部２の周方向の略１／２の領域に亘って延びて上面２ａの外周側から上方に突出している。 The upper surface 2a of the upper edge portion 2 is provided with two standing wall portions 21 and 21 that are rotationally symmetric with respect to the center of the upper edge portion 2. The standing wall portions 21 and 21 each extend over a region of approximately 1/2 in the circumferential direction of the upper edge portion 2 and project upward from the outer peripheral side of the upper surface 2a.

図５に示すように、立壁部２１，２１は、ヘアキヤッチャー１の周方向に沿う一方に導入端部２１ａ，２１ａを有し、他方に終端部２１ｂ，２１ｂを有する。立壁部２１，２１は、導入端部２１ａ，２１ａから終端部２１ｂ，２１ｂに向けて時計方向に延びている。導入端部２１ａ，２１ａは、上縁部２の上面２ａに１８０°対向するように配置される。終端部２１ｂ，２１ｂは、それぞれもう一方の立壁部２１，２１の導入端部２１ａ，２１ａの近傍から、上縁部２の内側に湾曲し、貯水部３に向けて下降している。 As shown in FIG. 5, the standing wall portions 21 and 21 have introduction ends 21a and 21a on one side along the circumferential direction of the hair catcher 1 and end portions 21b and 21b on the other side. The vertical wall portions 21 and 21 extend clockwise from the introduction ends 21a and 21a toward the terminal portions 21b and 21b. The introduction end portions 21a and 21a are arranged so as to face the upper surface 2a of the upper edge portion 2 by 180 °. The end portions 21b and 21b are curved inward of the upper edge portion 2 from the vicinity of the introduction ends 21a and 21a of the other standing wall portions 21 and 21, respectively, and descend toward the water storage portion 3.

２つの立壁部２１，２１のうちの一方には、立壁部２１の上端からヘアキヤッチャー１の径方向の外側に向けて張り出す板状の把手部２２が設けられる。 One of the two standing wall portions 21 and 21 is provided with a plate-shaped handle portion 22 that projects outward from the upper end of the standing wall portion 21 in the radial direction of the hair catcher 1.

貯水部３は、ヘアキャッチャー１の底部に配置され、上縁部２の内側に流入する水の一部を一時的に貯水する。貯水部３は、底面部３１と、側面部３２と、水抜き孔３３と、を有する。 The water storage unit 3 is arranged at the bottom of the hair catcher 1 and temporarily stores a part of the water flowing into the inside of the upper edge portion 2. The water storage unit 3 has a bottom surface portion 31, a side surface portion 32, and a drain hole 33.

底面部３１は、ヘアキャッチャー１の最底部であり、上縁部２の内周よりも小径な平坦な円形板によって構成される。底面部３１は、上縁部２と略平行で、上縁部２と同芯状に配置される。 The bottom surface portion 31 is the bottommost portion of the hair catcher 1 and is composed of a flat circular plate having a diameter smaller than the inner circumference of the upper edge portion 2. The bottom surface portion 31 is substantially parallel to the upper edge portion 2 and is arranged concentrically with the upper edge portion 2.

側面部３２は、底面部３１の外周から斜め上方に拡開するように傾斜状に延びている。側面部３２は、上縁部２と底面部３１との間において、底面部３１から一定の高さに亘って、貯水部３の周方向に帯状に延在する。側面部３２は、貯水部３に水を一時的に貯水するための側壁面を構成する。 The side surface portion 32 extends obliquely upward from the outer circumference of the bottom surface portion 31 in an inclined manner. The side surface portion 32 extends in a band shape in the circumferential direction of the water storage portion 3 from the bottom surface portion 31 to a certain height between the upper edge portion 2 and the bottom surface portion 31. The side surface portion 32 constitutes a side wall surface for temporarily storing water in the water storage portion 3.

水抜き孔３３は、底面部３１と側面部３２との境界部に、ヘアキヤッチャー１の周方向に間隔をおいて複数設けられる。本実施形態では８個の水抜き孔３３が貯水部３の周方向に均等間隔で設けられている。しかし、水抜き孔３３の数は８個に限定されない。 A plurality of drain holes 33 are provided at the boundary between the bottom surface portion 31 and the side surface portion 32 at intervals in the circumferential direction of the hair catcher 1. In this embodiment, eight drain holes 33 are provided at equal intervals in the circumferential direction of the water storage unit 3. However, the number of drain holes 33 is not limited to eight.

排水部４は、上縁部２の内周側と貯水部３との間を繋ぐように配置され、ヘアキャッチャー１の側面の大部分を占めている。排水部４は、ヘアキャッチャー１の周方向において、立壁部２１，２１の導入端部２１ａ，２１ａの近傍から、立壁部２１，２１の終端部２１ｂ，２１ｂに亘って形成される。ヘアキャッチャー１の周方向に隣り合う導入端部２１ａと終端部２１ｂとの間には、後述する導水部５が配置され、排水部４は設けられていない。したがって、ヘアキャッチャー１の側面には、２つの導水部５，５を挟んで２つの排水部４，４が設けられている。 The drainage portion 4 is arranged so as to connect the inner peripheral side of the upper edge portion 2 and the water storage portion 3, and occupies most of the side surface of the hair catcher 1. The drainage portion 4 is formed in the circumferential direction of the hair catcher 1 from the vicinity of the introduction ends 21a and 21a of the vertical wall portions 21 and 21 to the terminal portions 21b and 21b of the vertical wall portions 21 and 21. A water guide portion 5 to be described later is arranged between the introduction end portion 21a and the end portion 21b adjacent to each other in the circumferential direction of the hair catcher 1, and the drainage portion 4 is not provided. Therefore, on the side surface of the hair catcher 1, two drainage portions 4 and 4 are provided so as to sandwich the two water guide portions 5 and 5.

排水部４は、ヘアキャッチャー１の内側と外側との間で水を通流可能な複数の開口４１を有する。詳しくは、排水部４は、複数の縦リブ部４２と複数の横リブ部４３とによって格子状に形成される。複数の縦リブ部４２は、ヘアキャッチャー１の周方向に間隔をおいて配置され、貯水部３から上縁部２に向かうに従って外側に拡開するように、上縁部２と貯水部３とを斜めに繋いでいる。複数の横リブ部４３は、ヘアキャッチャー１の高さ方向に間隔をおいて平行に配置され、ヘアキャッチャー１の周方向に隣り合う縦リブ部４２，４２を繋ぐように、ヘアキャッチャー１の周方向に延びている。開口４１は、２本の縦リブ部４２と２本の横リブ部４３とによって囲まれる矩形領域によって構成される。 The drainage unit 4 has a plurality of openings 41 through which water can flow between the inside and the outside of the hair catcher 1. Specifically, the drainage portion 4 is formed in a grid pattern by the plurality of vertical rib portions 42 and the plurality of horizontal rib portions 43. The plurality of vertical rib portions 42 are arranged at intervals in the circumferential direction of the hair catcher 1, and are arranged with the upper edge portion 2 and the water storage portion 3 so as to expand outward from the water storage portion 3 toward the upper edge portion 2. Are connected diagonally. The plurality of horizontal rib portions 43 are arranged in parallel at intervals in the height direction of the hair catcher 1, and the circumference of the hair catcher 1 is connected so as to connect the vertically adjacent vertical rib portions 42, 42 in the circumferential direction of the hair catcher 1. It extends in the direction. The opening 41 is composed of a rectangular region surrounded by two vertical rib portions 42 and two horizontal rib portions 43.

図６に示すように、縦リブ部４２の断面形状は、それぞれ三角形状を有する。詳しくは、縦リブ部４２は、図５及び図６中の矢印で示すように、立壁部２１，２１の導入端部２１ａ，２１ａと終端部２１ｂ，２１ｂとの間から上縁部２の内側に流入した水の流れに対して斜めに配置される傾斜面４２ａを有する。傾斜面４２ａは、排水部４の内側に向いて配置され、排水部４の内側から外側に向かうに従って、水の流れ方向の上流側へ延びるように形成されている。そのため、ヘアキャッチャー１の外側の排水トラップ部２０１内を流れる水の一部は、図６中の矢印で示すように、縦リブ部４２の傾斜面４２ａに当たって排水部４の内側に向きを変え、排水部４の外側から開口４１を通って内側へ流れる。 As shown in FIG. 6, the cross-sectional shape of the vertical rib portion 42 has a triangular shape. Specifically, as shown by the arrows in FIGS. 5 and 6, the vertical rib portion 42 is inside the upper edge portion 2 from between the introduction ends 21a and 21a and the end portions 21b and 21b of the vertical wall portions 21 and 21. It has an inclined surface 42a arranged obliquely with respect to the flow of water flowing into the water. The inclined surface 42a is arranged so as to face the inside of the drainage portion 4, and is formed so as to extend toward the upstream side in the water flow direction from the inside to the outside of the drainage portion 4. Therefore, as shown by the arrow in FIG. 6, a part of the water flowing in the drain trap portion 201 on the outside of the hair catcher 1 hits the inclined surface 42a of the vertical rib portion 42 and turns to the inside of the drain portion 4. It flows inward from the outside of the drainage portion 4 through the opening 41.

導水部５は、上縁部２の内周側と貯水部３との間を繋ぐように配置される。上述したように、ヘアキャッチャー１の側面には、２つの導水部５，５を挟んで２つの排水部４，４が設けられる。導水部５，５の上端部５ａ，５ａは、隣り合う立壁部２１，２１の導入端部２１ａ，２１ａと終端部２１ｂ，２１ｂとの間に配置される。導水部５，５の下端部５ｂ，５ｂは、貯水部３の側面部３２の上端部にそれぞれ一体に連結される。 The water guide portion 5 is arranged so as to connect the inner peripheral side of the upper edge portion 2 and the water storage portion 3. As described above, two drainage portions 4 and 4 are provided on the side surface of the hair catcher 1 with the two water guide portions 5 and 5 interposed therebetween. The upper end portions 5a and 5a of the water guide portions 5 and 5 are arranged between the introduction end portions 21a and 21a and the terminal portions 21b and 21b of the adjacent standing wall portions 21 and 21. The lower end portions 5b and 5b of the water guide portions 5 and 5 are integrally connected to the upper end portions of the side surface portions 32 of the water storage portion 3, respectively.

２つの導水部５，５は、ヘアキャッチャー１の周方向に１８０°離れて配置されている。導水部５，５は、ヘアキャッチャー１の平面視において、立壁部２１，２１の導入端部２１ａ，２１ａと終端部２１ｂ，２１ｂとの間から貯水部３に向けてわずかに時計方向に傾斜するように延び、貯水部３の側面部３２の上端に連結している。導水部５，５には開口が設けられていない。そのため、導水部５，５は、導入端部２１ａと終端部２１ｂとの間から流入した水の一部を、そのまま貯水部３に向けて導くように機能する。 The two water guiding portions 5 and 5 are arranged 180 ° apart in the circumferential direction of the hair catcher 1. In the plan view of the hair catcher 1, the water guide portions 5 and 5 are slightly inclined clockwise toward the water storage portion 3 from between the introduction ends 21a and 21a and the end portions 21b and 21b of the standing wall portions 21 and 21. And is connected to the upper end of the side surface portion 32 of the water storage portion 3. The water guides 5 and 5 are not provided with openings. Therefore, the water guide portions 5 and 5 function to guide a part of the water flowing in from between the introduction end portion 21a and the end portion 21b toward the water storage portion 3 as it is.

立壁部２１，２１の終端部２１ｂ，２１ｂは、導水部５，５の高さ方向の中途部近傍まで延びている。これによって、導入端部２１ａと終端部２１ｂとの間から流入する水の一部は、導水部５，５に案内されて貯水部３に向けて円滑に流下する。 The terminal portions 21b and 21b of the vertical wall portions 21 and 21 extend to the vicinity of the middle portion in the height direction of the water guiding portions 5 and 5. As a result, a part of the water flowing in from between the introduction end portion 21a and the end portion 21b is guided by the water guide portions 5 and 5 and smoothly flows down toward the water storage portion 3.

係合凹部６は、洗い場排水口２０３の内周面に設けられる係合突部２０３ａと係合することによって、ヘアキャッチャー１が排水トラップ部２０１内の排水によって浮き上がらないように固定するための係止手段である。本実施形態のヘアキャッチャー１は、２つの導水部５，５の外面５ｃ，５ｃにそれぞれ係合凹部６，６が設けられる。２つの係合凹部６，６は、ヘアキャッチャー１の周方向に１８０゜離れて配置されている。 The engaging recess 6 engages with the engaging protrusion 203a provided on the inner peripheral surface of the washing place drain port 203 to fix the hair catcher 1 so as not to be lifted by the drainage in the drain trap portion 201. It is a stopping means. In the hair catcher 1 of the present embodiment, engaging recesses 6 and 6 are provided on the outer surfaces 5c and 5c of the two water guiding portions 5 and 5, respectively. The two engaging recesses 6 and 6 are arranged 180 ° apart in the circumferential direction of the hair catcher 1.

係合凹部６は、図８及び図９に示すように、上縁部２と接する導水部５の上端部５ａの外面５ｃから径方向外側に突出する突出部６１を有する。突出部６１は、中実状のブロックからなる。突出部６１は、導水部５の外面５ｃに、樹脂によって導水部５と一体成形された一体成形部である。突出部６１におけるヘアキャッチャー１の径方向の外側に配置される突出部６１の外端面６１ａは、上縁部２の外周面２ｂと面一状に配置される。 As shown in FIGS. 8 and 9, the engaging recess 6 has a protruding portion 61 protruding outward in the radial direction from the outer surface 5c of the upper end portion 5a of the water guiding portion 5 in contact with the upper edge portion 2. The protrusion 61 is made of a solid block. The protruding portion 61 is an integrally molded portion integrally molded with the water guiding portion 5 by a resin on the outer surface 5c of the water guiding portion 5. The outer end surface 61a of the protrusion 61 arranged on the outer side of the hair catcher 1 in the protrusion 61 in the radial direction is arranged flush with the outer peripheral surface 2b of the upper edge portion 2.

係合凹部６は、導水部５の外面５ｃに設けられるため、排水部４の開口４１を閉塞することはない。通常、排水部４の開口４１の数及び開口面積は、ヘアキャッチャー１の内側に流入した所定量の水を、開口４１を通してヘアキャッチャー１の外側に所定の時間で排水されるように設計される。係合凹部６が開口４１の一部を閉塞していると、その部位ではヘアキャッチャー１の外側への排水が阻害されるため、所定量の水を所定の時間内に排水することが困難になる場合がある。しかし、この係合凹部６は、導水部５の外面５ｃに設けられるため、排水部４の開口４１の通流を妨げない。排水部４には所望の数の開口４１を設けることができる。そのため、ヘアキャッチャー１の外側面に係合凹部６を設けても、ヘアキャッチャー１の排水性能に影響を与えることはない。 Since the engaging recess 6 is provided on the outer surface 5c of the water guiding portion 5, the opening 41 of the drainage portion 4 is not blocked. Usually, the number of openings 41 and the opening area of the drainage portion 4 are designed so that a predetermined amount of water flowing into the inside of the hair catcher 1 is drained to the outside of the hair catcher 1 through the openings 41 in a predetermined time. .. If the engaging recess 6 closes a part of the opening 41, drainage to the outside of the hair catcher 1 is hindered at that portion, so that it is difficult to drain a predetermined amount of water within a predetermined time. May become. However, since the engaging recess 6 is provided on the outer surface 5c of the water guide portion 5, it does not obstruct the flow of the opening 41 of the drainage portion 4. A desired number of openings 41 can be provided in the drainage portion 4. Therefore, even if the engaging recess 6 is provided on the outer surface of the hair catcher 1, the drainage performance of the hair catcher 1 is not affected.

係合凹部６は、突出部６１の外端面６１ａから径方向の内側に向けて凹設される。詳しくは、係合凹部６は、突出部６１の外端面６１ａにおいて、周方向に開放する横向き略Ｕ字状に形成される。このような溝状の係合凹部６は、突出部６１におけるいわゆる肉盗みを構成し、突出部６１の成形時の収縮に伴うヒケの発生を抑制することができる。そのため、本実施形態のヘアキャッチャー１は、成形精度に優れる。 The engaging recess 6 is recessed inward in the radial direction from the outer end surface 61a of the protruding portion 61. Specifically, the engaging recess 6 is formed in a laterally substantially U-shape that opens in the circumferential direction on the outer end surface 61a of the protruding portion 61. Such a groove-shaped engaging recess 6 constitutes a so-called meat stealing in the protruding portion 61, and can suppress the occurrence of sink marks due to shrinkage of the protruding portion 61 during molding. Therefore, the hair catcher 1 of the present embodiment is excellent in molding accuracy.

突出部６１の下端面６１ｂは、図４に示すように、略水平面によって構成される。この下端面６１ｂと導水部５の外面５ｃとは、鈍角で連続して繋がる連続面を形成している。「連続して繋がる」とは、突出部６１の下端面６１ｂと導水部５の外面５ｃとの間に溝が設けられておらず、下端面６１ｂと外面５ｃとが単一の境界線６１ｃによって繋がっていることを意味する。これによって、ヘアキャッチャー１の外側の旋回流は、突出部６１の下端面６１ｂ、導水部５の外面５ｃ及び両者の境界線６１ｃに沿ってスムーズに流れる。そのため、その旋回流に含まれる髪の毛も旋回流に沿って流れ、突出部６１に絡みつくことが防止される。 As shown in FIG. 4, the lower end surface 61b of the protrusion 61 is formed by a substantially horizontal plane. The lower end surface 61b and the outer surface 5c of the water guiding portion 5 form a continuous surface that is continuously connected at an obtuse angle. "Continuously connected" means that no groove is provided between the lower end surface 61b of the protruding portion 61 and the outer surface 5c of the water guiding portion 5, and the lower end surface 61b and the outer surface 5c are connected by a single boundary line 61c. It means that they are connected. As a result, the swirling flow on the outside of the hair catcher 1 smoothly flows along the lower end surface 61b of the protruding portion 61, the outer surface 5c of the water guiding portion 5, and the boundary line 61c between the two. Therefore, the hair included in the swirling flow also flows along the swirling flow and is prevented from being entangled with the protrusion 61.

突出部６１におけるヘアキヤッチャー１の周方向の端面６１ｄは、わずかに下向きに傾斜するように形成されている。この端面６１ｄも、導水部５の外面５ｃと鈍角で連続して繋がる連続面を形成している。そのため、突出部６１の端面６１ｄに当たった水に含まれる髪の毛が端面６１ｄに付着することが抑制される。 The circumferential end face 61d of the hair catcher 1 in the protrusion 61 is formed so as to be slightly inclined downward. This end surface 61d also forms a continuous surface that is continuously connected to the outer surface 5c of the water conveyance portion 5 at an obtuse angle. Therefore, it is possible to prevent the hair contained in the water that hits the end face 61d of the protrusion 61 from adhering to the end face 61d.

次に、ヘアキャッチャー１の取り付け及び使用状態について説明する。まず、ヘアキャッチャー１は、２つの係合凹部６，６が洗い場排水口２０３の周方向に隣接する２つの係合突部２０３ａの間に配置されるように洗い場排水口２０３に嵌合される。嵌合後、使用者が、把手部２２を持って、ヘアキャッチャー１を時計方向に所定角度回転させると、２つの係合凹部６，６が２つの係合突部２０３ａに対してそれぞれ係合する。これによって、ヘアキャッチャー１は、洗い場排水口２０３に固定される。その後、排水トラップ部２０１の内部に大量の水が流れても、ヘアキャッチャー１は、洗い場排水口２０３から浮き上がることはない。 Next, the attachment and use state of the hair catcher 1 will be described. First, the hair catcher 1 is fitted to the washing place drainage port 203 so that the two engaging recesses 6 and 6 are arranged between the two engaging protrusions 203a adjacent to each other in the circumferential direction of the washing place drainage port 203. .. After fitting, when the user holds the handle portion 22 and rotates the hair catcher 1 clockwise by a predetermined angle, the two engaging recesses 6 and 6 engage with the two engaging protrusions 203a, respectively. do. As a result, the hair catcher 1 is fixed to the washing place drain port 203. After that, even if a large amount of water flows inside the drain trap portion 201, the hair catcher 1 does not float from the washing place drain port 203.

洗い場床１００上の水は、洗い場床１００の勾配によって洗い場排水口２０３に向けて流れ、ヘアキャッチャー１に到達する。ヘアキャッチャー１に到達した水は、ヘアキャッチャー１の立壁部２１，２１に当たり、立壁部２１，２１の外面に沿って流れた後、立壁部２１，２１の導入端部２１ａと終端部２１ｂとの間から、ヘアキャッチャー１の内部に流入する。 The water on the washing place floor 100 flows toward the washing place drain port 203 by the gradient of the washing place floor 100 and reaches the hair catcher 1. The water that has reached the hair catcher 1 hits the standing wall portions 21 and 21 of the hair catcher 1 and flows along the outer surface of the standing wall portions 21 and 21. From between, it flows into the inside of the hair catcher 1.

ヘアキャッチャー１の内部に流入した水の大部分は、立壁部２１，２１の導入端部２１ａと終端部２１ｂとの間から終端部２１ｂの湾曲形状に沿って案内され、図５中に矢印で示すように、ヘアキャッチャー１の内部を平面視で時計方向に旋回しながら流下する。流下した水の一部は、排水部４の開口４１を内側から外側に向けて流れる。 Most of the water that has flowed into the hair catcher 1 is guided along the curved shape of the end portion 21b from between the introduction end portion 21a and the end portion 21b of the standing wall portions 21 and 21, and is indicated by an arrow in FIG. As shown, the inside of the hair catcher 1 flows down while turning clockwise in a plan view. A part of the flowing water flows from the inside to the outside through the opening 41 of the drainage portion 4.

ヘアキャッチャー１の内部に流入した水の一部は、上縁部２から貯水部３に向けて延びる導水部５によってそのまま貯水部３に導かれる。水に含まれる髪の毛も、導水部５を通って貯水部３に流れる。貯水部３の水抜き孔３３の数は、排水部４の開口４１の数に比べて遥かに少ないため、貯水部３に導かれた髪の毛を含む水は、貯水部３に一時的に貯水される。 A part of the water that has flowed into the inside of the hair catcher 1 is directly guided to the water storage section 3 by the water guiding section 5 extending from the upper edge portion 2 toward the water storage section 3. Hair contained in water also flows to the water storage unit 3 through the water conduction unit 5. Since the number of drain holes 33 in the water storage section 3 is much smaller than the number of openings 41 in the drainage section 4, the water containing hair guided to the water storage section 3 is temporarily stored in the water storage section 3. NS.

排水トラップ部２０１内に流れ込む水量が多くなると、排水トラップ部２０１の内部に、排水トラップ部２０１の平面視において時計方向の旋回流が発生する。排水トラップ部２０１内の旋回流の一部は、図６に示すように、排水部４の縦リブ部４２の傾斜面４２ａに当たって排水部４の内側に向きを変え、排水部４の外側から開口４１を通って内側へ流入し、排水部４の内側の旋回流と合流する。このとき、排水トラップ部２０１内の旋回流に含まれる髪の毛も、開口４１を通って流入する。 When the amount of water flowing into the drain trap section 201 increases, a clockwise swirling flow is generated inside the drain trap section 201 in a plan view of the drain trap section 201. As shown in FIG. 6, a part of the swirling flow in the drain trap portion 201 hits the inclined surface 42a of the vertical rib portion 42 of the drain portion 4 and turns to the inside of the drain portion 4, and opens from the outside of the drain portion 4. It flows inward through 41 and joins the swirling flow inside the drainage unit 4. At this time, the hair contained in the swirling flow in the drain trap portion 201 also flows in through the opening 41.

排水部４の外側から開口４１を通って内側へ水が流入することによって貯水部３にさらに貯水された水は、水抜き孔３３から徐々に排出される。これによって、水に含まれる髪の毛が貯水部３内に纏められる。 The water further stored in the water storage unit 3 is gradually discharged from the drain hole 33 by the water flowing inward from the outside of the drainage unit 4 through the opening 41. As a result, the hair contained in the water is collected in the water storage unit 3.

排水完了後、使用者が把手部２２を持ってヘアキャッチャー１を反時計方向に回転させると、係合凹部６と係合突部２０３ａとの係合が解除される。これによって、使用者は、ヘアキャッチャー１を洗い場排水口２０３から取り外し、貯水部３に捕集された髪の毛を清掃することができる。 After the drainage is completed, when the user holds the handle portion 22 and rotates the hair catcher 1 counterclockwise, the engagement between the engaging recess 6 and the engaging protrusion 203a is released. As a result, the user can remove the hair catcher 1 from the washing place drainage port 203 and clean the hair collected in the water storage unit 3.
