Description

本開示は、ヘアキャッチャーに関する。 This 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 installed on the drains of bathrooms and washbasins to prevent hair and small debris from going down the drain and clogging the pipes. Hair catchers are prone to getting tangled or caught, so cleaning and collecting hair is time-consuming.

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。 Patent Document 1 discloses a technology that uses drainage to generate a swirling flow inside the hair catcher, thereby collecting hair inside the hair catcher and making it easier to clean and collect hair. This hair catcher has a bottom mesh section with many holes drilled in the circumferential direction from the center of the bottom to the sides, a non-mesh section that is located above the bottom mesh section and has no holes, and an intermediate mesh section that is located above the non-mesh section and has many holes drilled in the circumferential direction, and is set on the drain of the bathroom washing area.

特開２０１１－２３１５０７号公報JP 2011-231507 A

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。 The hair catcher described in Patent Document 1 is set by placing it on the drain, so if a large amount of water flows into the drain, the hair catcher will float up from the drain. If the hair catcher floats up, it cannot generate a swirling flow, causing hair to scatter, which makes cleaning difficult.

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。 To prevent the hair catcher from floating up, it is possible to provide a locking means on the outer surface of the hair catcher to lock it into the drain. However, since the outer surface of the hair catcher has many openings for draining water, providing a locking means on the outer surface of the hair catcher would result in the locking means blocking the openings, which would affect the drainage performance.

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 necessary to prevent the hair catcher from floating up from the drain 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 has an upper edge, a water storage section disposed at the bottom, a drain section disposed between the upper edge and the water storage section and having a number of openings for draining to the outside a portion of the water that has flowed into the interior, a water guide section disposed to connect the upper edge and the water storage section and directing a portion of the water that has flowed in from the upper edge toward the water storage section, and an engagement recess disposed on the outer surface of the water guide section and engaging with an engagement protrusion provided on the inner peripheral surface of the drain port.

以下、本開示の一実施形態について図面を参照して説明する。図１及び図２に示すように、ヘアキャッチャー１は、浴室の洗い場床１００に設けられる浴室排水装置２００に取り付けられる。 An embodiment of the present disclosure will now be described with reference to the drawings. As shown in Figs. 1 and 2, the hair catcher 1 is attached to a bathroom drainage device 200 provided on the floor 100 of the bathroom wash area.

浴室排水装置２００は、排水トラップ部２０１と、浴槽の底部に開口するように配置される浴槽排水口２０２と、排水トラップ部２０１の上部に開口し、ヘアキャッチャー１が取り付けられる洗い場排水口２０３と、排水トラップ部２０１と浴槽排水口２０２とを接続する接続管２０４と、排水トラップ部２０１内の水を排水する排水管２０５と、を有する。浴槽排水口２０２からの排水ＦＬは、図２に示すように接続管２０４を通って排水トラップ部２０１に流入する。洗い場排水口２０３は、洗い場床１００に開口し、排水トラップ部２０１の上部に開口している。図１では、洗い場床１００に隣接して設けられる浴槽の図示を省略している。 The bathroom drainage device 200 has a drain trap section 201, a bathtub drain 202 arranged to open to the bottom of the bathtub, a washing area drain 203 that opens to the top of the drain trap section 201 and to which a hair catcher 1 is attached, a connecting pipe 204 that connects the drain trap section 201 and the bathtub drain 202, and a drain pipe 205 that drains the water in the drain trap section 201. The drain FL from the bathtub drain 202 flows into the drain trap section 201 through the connecting pipe 204 as shown in FIG. 2. The washing area drain 203 opens to the washing area floor 100 and opens to the top of the drain trap section 201. In FIG. 1, the bathtub provided adjacent to the washing area 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。 2, the inner circumferential surface of the washing area drain outlet 203 has multiple engaging protrusions 203a. The engaging protrusions 203a are parts that fix the hair catcher 1 to the washing area drain outlet 203 by engaging with the engaging recesses 6, which are provided on the outer circumferential surface of the hair catcher 1 and will be described later. This prevents the hair catcher 1 from floating up from the washing area drain outlet 203 even if a large amount of water flows into the washing area drain outlet 203. In this embodiment, four engaging protrusions 203a are arranged on the inner circumferential surface of the washing area drain outlet 203 at an angle of 90°. However, it is sufficient that the inner circumferential surface of the washing area drain outlet 203 has at least two engaging protrusions 203a that engage with the two engaging recesses 6, 6, which will be described later.

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 Figures 3, 4 and 5, the hair catcher 1 is a resin molded product that is integrally equipped with an upper edge 2 located at the top of the hair catcher 1, a water storage section 3 located at the bottom of the hair catcher 1, a drainage section 4 located between the upper edge 2 and the water storage section 3, a water guide section 5 provided to connect the upper edge 2 and the water storage section 3, and an engagement recess 6 that engages with an engagement protrusion 203a of the washing area drain outlet 203. The hair catcher 1 is formed in a mortar shape that gradually narrows from the upper edge 2 toward the water storage section 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。 As shown by the arrows in Figure 5, the X direction of the hair catcher 1 when viewed from above is defined as the circumferential direction of the hair catcher 1. When viewed from above, the direction extending radially from the center of the centrally located water storage section 3 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 a circular ring shape with a predetermined width. The upper edge portion 2 has an outer diameter that is approximately the same as the inner diameter of the washing area drain outlet 203 excluding the engagement protrusion 203a, and fits into the inner peripheral surface of the circular washing area drain outlet 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。 Two vertical walls 21, 21 are provided on the upper surface 2a of the upper edge 2, which are rotationally symmetrical with respect to the center of the upper edge 2. Each of the vertical walls 21, 21 extends over approximately half the area of the upper edge 2 in the circumferential direction and protrudes upward from the outer periphery 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 vertical wall portions 21, 21 have an introduction end 21a, 21a on one side along the circumferential direction of the hair catcher 1, and an end end 21b, 21b on the other side. The vertical wall portions 21, 21 extend clockwise from the introduction end 21a, 21a to the end end 21b, 21b. The introduction end 21a, 21a is disposed so as to face the upper surface 2a of the upper edge portion 2 at 180°. The end end 21b, 21b curves inward from the vicinity of the introduction end 21a, 21a of the other vertical wall portion 21, 21, respectively, toward the inside of the upper edge portion 2 and descends 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 vertical wall portions 21, 21 is provided with a plate-shaped handle portion 22 that protrudes from the upper end of the vertical wall portion 21 toward the outside 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 section 3 is located at the bottom of the hair catcher 1 and temporarily stores some of the water that flows inside the upper edge section 2. The water storage section 3 has a bottom section 31, a side section 32, and a water drainage 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 with a smaller diameter than the inner circumference of the upper edge portion 2. The bottom surface portion 31 is approximately 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 portion 32 extends obliquely from the outer periphery of the bottom portion 31 so as to expand obliquely upward. The side portion 32 extends in a band shape in the circumferential direction of the water storage portion 3 between the upper edge portion 2 and the bottom portion 31, for a certain height from the bottom portion 31. The side portion 32 forms 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。 The drain holes 33 are provided at intervals around the circumference of the hair catcher 1 at the boundary between the bottom surface 31 and the side surface 32. In this embodiment, eight drain holes 33 are provided at equal intervals around the circumference of the water storage section 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 section 4 is arranged to connect the inner periphery of the upper edge 2 and the water storage section 3, and occupies most of the side surface of the hair catcher 1. The drainage section 4 is formed in the circumferential direction of the hair catcher 1, from near the introduction ends 21a, 21a of the vertical walls 21, 21 to the terminal ends 21b, 21b of the vertical walls 21, 21. A water guide section 5, which will be described later, is arranged between the introduction ends 21a and terminal ends 21b that are adjacent in the circumferential direction of the hair catcher 1, and no drainage section 4 is provided. Therefore, two drainage sections 4, 4 are provided on the side surface of the hair catcher 1, sandwiching the two water guide sections 5, 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 section 4 has a number of openings 41 that allow water to flow between the inside and outside of the hair catcher 1. More specifically, the drainage section 4 is formed in a lattice pattern by a number of vertical rib sections 42 and a number of horizontal rib sections 43. The vertical rib sections 42 are arranged at intervals in the circumferential direction of the hair catcher 1, and connect the upper edge section 2 and the water storage section 3 diagonally so as to expand outward as they move from the water storage section 3 toward the upper edge section 2. The horizontal rib sections 43 are arranged in parallel at intervals in the height direction of the hair catcher 1, and extend in the circumferential direction of the hair catcher 1 so as to connect adjacent vertical rib sections 42, 42 in the circumferential direction of the hair catcher 1. The opening 41 is formed by a rectangular area surrounded by two vertical rib sections 42 and two horizontal rib sections 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 vertical rib portion 42 has a triangular cross-sectional shape. More specifically, the vertical rib portion 42 has an inclined surface 42a that is arranged diagonally with respect to the flow of water that flows into the inside of the upper edge portion 2 from between the inlet end 21a, 21a and the end end 21b, 21b of the vertical wall portion 21, 21, as shown by the arrows in FIG. 5 and FIG. 6. The inclined surface 42a is arranged facing the inside of the drainage portion 4, and is formed so as to extend upstream in the direction of the water flow as it moves from the inside to the outside of the drainage portion 4. Therefore, a part of the water flowing in the drainage trap portion 201 on the outside of the hair catcher 1 hits the inclined surface 42a of the vertical rib portion 42 and changes direction to the inside of the drainage portion 4, as shown by the arrows in FIG. 6, and flows from the outside of the drainage portion 4 to the inside 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 section 5 is arranged to connect the inner periphery of the upper edge section 2 and the water storage section 3. As described above, two drainage sections 4, 4 are provided on the side of the hair catcher 1, sandwiching the two water guide sections 5, 5. The upper ends 5a, 5a of the water guide sections 5, 5 are arranged between the inlet ends 21a, 21a and the end ends 21b, 21b of the adjacent vertical wall sections 21, 21. The lower ends 5b, 5b of the water guide sections 5, 5 are each integrally connected to the upper end of the side section 32 of the water storage section 3.

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 guide sections 5, 5 are arranged 180° apart in the circumferential direction of the hair catcher 1. In a plan view of the hair catcher 1, the water guide sections 5, 5 extend from between the inlet ends 21a, 21a and the end ends 21b, 21b of the vertical walls 21, 21 toward the water storage section 3 at a slight clockwise incline, and are connected to the upper end of the side section 32 of the water storage section 3. The water guide sections 5, 5 do not have an opening. Therefore, the water guide sections 5, 5 function to guide a portion of the water that flows in from between the inlet ends 21a, 21a and the end ends 21b directly toward the water storage section 3.

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 end portions 21b, 21b of the vertical walls 21, 21 extend to near the midpoint of the height of the water conveying sections 5, 5. As a result, some of the water flowing in between the inlet end 21a and the end portion 21b is guided by the water conveying sections 5, 5 and flows smoothly down toward the water storage section 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 engagement recess 6 is a locking means for fixing the hair catcher 1 so that it does not float up due to the drainage in the drain trap section 201 by engaging with the engagement protrusion 203a provided on the inner peripheral surface of the washing area drain outlet 203. In this embodiment, the hair catcher 1 is provided with engagement recesses 6, 6 on the outer surfaces 5c, 5c of the two water guide sections 5, 5. The two engagement recesses 6, 6 are positioned 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 Figures 8 and 9, the engagement recess 6 has a protrusion 61 that protrudes radially outward from the outer surface 5c of the upper end 5a of the water guide section 5 that contacts the upper edge section 2. The protrusion 61 is made of a solid block. The protrusion 61 is an integrally molded part that is molded integrally with the water guide section 5 using resin on the outer surface 5c of the water guide section 5. The outer end surface 61a of the protrusion 61, which is located radially outward of the hair catcher 1, is located flush with the outer peripheral surface 2b of the upper edge section 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。 The engaging recess 6 is provided on the outer surface 5c of the water guide 5, so it does not block the opening 41 of the drainage section 4. Usually, the number and opening area of the openings 41 of the drainage section 4 are designed so that a predetermined amount of water that has flowed into the inside of the hair catcher 1 is drained through the openings 41 to the outside of the hair catcher 1 in a predetermined time. If the engaging recess 6 blocks a part of the opening 41, drainage to the outside of the hair catcher 1 is hindered at that part, so it may be difficult to drain a predetermined amount of water within a predetermined time. However, since the engaging recess 6 is provided on the outer surface 5c of the water guide 5, it does not hinder the flow of water through the openings 41 of the drainage section 4. The drainage section 4 can be provided with a desired number of openings 41. Therefore, even if the engaging recess 6 is provided on the outer surface of the hair catcher 1, it does not affect the drainage performance of the hair catcher 1.

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 engagement recess 6 is recessed radially inward from the outer end surface 61a of the protruding portion 61. More specifically, the engagement recess 6 is formed in a generally horizontal U-shape that opens in the circumferential direction on the outer end surface 61a of the protruding portion 61. Such a groove-shaped engagement recess 6 constitutes a so-called material stealing hole in the protruding portion 61, and can suppress the occurrence of sink marks that accompany shrinkage during molding of the protruding portion 61. Therefore, the hair catcher 1 of this embodiment has excellent molding precision.

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。 The lower end surface 61b of the protrusion 61 is formed of a substantially horizontal surface as shown in FIG. 4. The lower end surface 61b and the outer surface 5c of the water guide 5 form a continuous surface that is continuously connected at an obtuse angle. "Continuously connected" means that there is no groove between the lower end surface 61b of the protrusion 61 and the outer surface 5c of the water guide 5, and the lower end surface 61b and the outer surface 5c are connected by a single boundary line 61c. This allows the swirling flow outside the hair catcher 1 to flow smoothly along the lower end surface 61b of the protrusion 61, the outer surface 5c of the water guide 5, and the boundary line 61c between them. Therefore, hair contained in the swirling flow also flows along the swirling flow, and is prevented from becoming entangled in 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 protruding portion 61 of the hair catcher 1 is formed to be slightly inclined downward. This end face 61d also forms a continuous surface that is connected to the outer surface 5c of the water guide portion 5 at an obtuse angle. Therefore, hair contained in the water that hits the end face 61d of the protruding portion 61 is prevented 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 installation and use of the hair catcher 1 will be described. First, the hair catcher 1 is fitted into the washing area drain outlet 203 so that the two engagement recesses 6, 6 are positioned between two engagement protrusions 203a adjacent in the circumferential direction of the washing area drain outlet 203. After fitting, when the user holds the handle portion 22 and rotates the hair catcher 1 clockwise a predetermined angle, the two engagement recesses 6, 6 respectively engage with the two engagement protrusions 203a. This fixes the hair catcher 1 to the washing area drain outlet 203. After that, even if a large amount of water flows inside the drain trap portion 201, the hair catcher 1 will not float up from the washing area drain outlet 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 area floor 100 flows toward the washing area drain 203 due to the slope of the washing area floor 100, and reaches the hair catcher 1. The water that reaches the hair catcher 1 hits the vertical walls 21, 21 of the hair catcher 1, flows along the outer surfaces of the vertical walls 21, 21, and then flows into the inside of the hair catcher 1 between the introduction end 21a and the end end 21b of the vertical walls 21, 21.

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 flows into the hair catcher 1 is guided between the inlet end 21a and the end 21b of the vertical walls 21, 21 along the curved shape of the end 21b, and flows down inside the hair catcher 1 while circling clockwise in a plan view, as shown by the arrow in Figure 5. Some of the water that flows down flows from the inside to the outside through the opening 41 of the drainage section 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。 Some of the water that flows into the hair catcher 1 is led directly to the water storage section 3 by the water guide section 5 that extends from the upper edge 2 toward the water storage section 3. Hair contained in the water also flows through the water guide section 5 into the water storage section 3. Since the number of drainage holes 33 in the water storage section 3 is far fewer than the number of openings 41 in the drain section 4, the water containing hair that is led to the water storage section 3 is temporarily stored in the water storage section 3.

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 swirling flow occurs inside the drain trap section 201 in a clockwise direction when viewed from above. As shown in FIG. 6, part of the swirling flow in the drain trap section 201 hits the inclined surface 42a of the vertical rib section 42 of the drain section 4 and changes direction to the inside of the drain section 4, flows from the outside of the drain section 4 to the inside through the opening 41, and merges with the swirling flow inside the drain section 4. At this time, hair contained in the swirling flow inside the drain trap section 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 section 3 as it flows in from the outside of the drain section 4 through the opening 41 is gradually drained from the water drainage hole 33. This allows the hair contained in the water to be collected inside the water storage section 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 draining is complete, the user holds the handle 22 and rotates the hair catcher 1 counterclockwise, which disengages the engagement recess 6 from the engagement protrusion 203a. This allows the user to remove the hair catcher 1 from the washing area drain 203 and clean up the hair that has been collected in the water storage section 3.
