Description

本発明は、例えば浴室における洗い場床の排水部に配設されるヘアキャッチャーに関する。 The present invention relates to, for example, a hair catcher disposed in a drainage section of a washroom floor in a bathroom.

浴室の洗い場床や洗面台等の排水口には、髪の毛やゴミなどで排水管が詰まることを防ぐためにヘアキャッチャーが設けられている。例えば、特許文献１には、流入した排水を保水する凹状の保水部と、保水部の上部から延出し、排水中の髪の毛の流出を抑止しながら保水部に入りきらない排水を流出させる上部排水流出部と、洗い場床からの排水を保水部へ導く排水導入部とを備えるヘアキャッチャーが開示されている。 A hair catcher is provided at the drain outlet of the bathroom washroom floor or wash basin to prevent the drain pipe from being clogged with hair or dust. For example, in Patent Document 1, a concave water-retaining portion that retains the inflowing drainage and an upper drainage that extends from the upper part of the water-retaining portion to prevent the outflow of hair in the drainage and allow the drainage that cannot fit in the water-retaining portion to flow out. A hair catcher including a drainage section and a drainage introduction section that guides drainage from the washing floor to a water retention section is disclosed.

特許文献１に記載のヘアキャッチャーは、排水導入部から保水部へ水を流して旋回流を発生させるが、排水導入部における勾配と保水部の内側面の勾配とで差異がある。このため、保水部へ水が流れ込む際に方向が変化し、旋回流に乱れが生じてしまう蓋然性があった。 The hair catcher described in Patent Document 1 causes water to flow from the drainage introduction portion to the water retention portion to generate a swirling flow, but there is a difference between the gradient in the drainage introduction portion and the gradient on the inner surface of the water retention portion. For this reason, there is a possibility that the direction changes when water flows into the water retention portion and the swirling flow is disturbed.

本発明は、斯かる事情に鑑みてなされたものであり、その目的とするところは、流れ込んだ水による旋回流が発生し易いヘアキャッチャーを提供することにある。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide a hair catcher in which a swirling flow due to the flowing water is likely to occur.

ヘアキャッチャー１００は、図２に示すように洗い場床８に設けられた排水口８１に設置され、上方を蓋体８２で覆われる。図２に示す例では、洗い場床８の孔部に取り付けられたフランジ部８０の内側面に爪８１ａが設けられており、上縁部１０に設けた係止部１０ａを爪８１ａに係止させて、ヘアキャッチャー１００を取り付けている。洗い場床８からの水は、立壁部５によって規制されて水切り部１へ流れ込む。尚、図２において、洗い場床８、排水口８１および蓋体８２は断面で表されている。 As shown in FIG. 2, the hair catcher 100 is installed at a drain port 81 provided on the washing floor 8 and is covered with a lid 82 above. In the example shown in FIG. 2, a claw 81a is provided on the inner side surface of the flange portion 80 attached to the hole portion of the washing place floor 8, and the locking portion 10a provided on the upper edge portion 10 is locked to the claw 81a. The hair catcher 100 is attached. The water from the washing place floor 8 is regulated by the standing wall portion 5 and flows into the draining portion 1. In FIG. 2, the washing place floor 8, the drain port 81, and the lid 82 are shown in cross section.

上縁部１０は円環状であり、リブ構造３によって貯水部２と接続される。洗い場床８からの水は上縁部１０を通って水切り部１の内側に流れ込む。リブ構造３は、複数の縦リブ３１および複数の横リブ３２を有し、上縁部１０と貯水部２とを接続する。縦リブ３１は貯水部２から上縁部１０へ放射状に延びており、上縁部１０から水切り部１の中央へ向かうにつれて下降する勾配を有している。縦リブ３１の勾配は、一定であっても変化してもよい。 The upper edge portion 10 has an annular shape and is connected to the water storage portion 2 by the rib structure 3.

The rib structure 3 has a plurality of vertical ribs 31 and a plurality of horizontal ribs 32, and connects the upper edge portion 10 and the water storage portion 2. The vertical rib 31 extends radially from the water storage portion 2 to the upper edge portion 10, and has a gradient that descends from the upper edge portion 10 toward the center of the draining portion 1. The gradient of the vertical rib 31 may be constant or variable.

図３を参照する。横リブ３２は、複数の縦リブ３１を周方向につなぐ円環状であり、貯水部２側から上方へ向かうにつれて内径が大きくなる。隣り合う縦リブ３１および隣り合う横リブ３２の間に通流孔４が形成されている。 See FIG. The horizontal rib 32 is an annular shape connecting a plurality of vertical ribs 31 in the circumferential direction, and the inner diameter increases from the water storage portion 2 side toward the upper side. A flow hole 4 is formed between the adjacent vertical ribs 31 and the adjacent horizontal ribs 32.

通流孔４は、水切り部１の内外を貫通するように設けられている。通流孔４には、水切り部１の内側における開口部４１の一部を覆うように排水抵抗部４２が形成されている。排水抵抗部４２は、開口部４１の縦リブ３１における縁部４１ａよりも、周方向において通流孔４の中央へ張り出すように設けられている。 The flow hole 4 is provided so as to penetrate the inside and outside of the draining portion 1. A drainage resistance portion 42 is formed in the flow hole 4 so as to cover a part of the opening 41 inside the draining portion 1. The drainage resistance portion 42 is provided so as to project toward the center of the flow hole 4 in the circumferential direction from the edge portion 41a of the vertical rib 31 of the opening 41.

排水抵抗部４２は、通流孔４内に臨み、外部水流を水切り部１の内側に誘導する外部水流誘導面４２ａを有する。外部水流誘導面４２ａは、水切り部１の内側から外側に向かうにつれて外部水流の上流側へ延びるように傾斜する面として形成されており、水切り部１の外側で流れる外部水流を水切り部１の内側に引き込む。尚、排水抵抗部４２は、外部水流誘導面４２ａを有しない構成であってもよい。 The drainage resistance portion 42 has an external water flow guiding surface 42a that faces the inside of the flow hole 4 and guides the external water flow to the inside of the draining portion 1. The external water flow guiding surface 42a is formed as a surface that inclines so as to extend toward the upstream side of the external water flow from the inside to the outside of the draining portion 1, and allows the external water flow flowing outside the draining portion 1 to flow inside the draining portion 1. Pull in to. The drainage resistance portion 42 may be configured not to have an external water flow guiding surface 42a.

排水抵抗部４２は、上縁部１０と貯水部２との間に形成される通流孔４の全てに設けられている。例えば、排水抵抗部４２は、上縁部１０に連なる上部に形成される通流孔４に設けられ、貯水部２側に近い通流孔４には設けないような構成としてもよい。また排水抵抗部４２は、水切り部１において設けられていなくてもよい。 The drainage resistance portion 42 is provided in all of the flow holes 4 formed between the upper edge portion 10 and the water storage portion 2. For example, the drainage resistance portion 42 may be provided in the through hole 4 formed in the upper portion connected to the upper edge portion 10 and may not be provided in the through hole 4 near the water storage portion 2. Further, the drainage resistance portion 42 may not be provided in the draining portion 1.

貯水部２は、底部２０、水抜き孔２１および底部２０を囲む側面部２２を有し、椀状に形成されている。貯水部２は、例えば皿状および深皿状等に形成されていてもよく、全体として円柱状、錐台状または半球状などの様々な形状とすることができる。水抜き孔２１は、貯水部２における側面部２２の下端部に横方向に内外を貫通するように設けられている。 The water storage portion 2 has a bottom portion 20, a drain hole 21, and a side surface portion 22 surrounding the bottom portion 20, and is formed in a bowl shape. The water storage portion 2 may be formed in a dish shape, a deep dish shape, or the like, and may have various shapes such as a columnar shape, a frustum shape, or a hemispherical shape as a whole. The drain hole 21 is provided at the lower end of the side surface portion 22 of the water storage portion 2 so as to penetrate the inside and outside in the lateral direction.

立壁部５は、上縁部１０から立ち上がるように上縁部１０に沿って円弧状に形成されており、２つの回転対象な第１立壁部５０および第２立壁部５５で構成されている。第１立壁部５０の導入端部５１および第２立壁部の終端部５７は、間隔を空けて対向しており、両者間に洗い場床８からの導水路が形成される。同様に、第２立壁部５５の導入端部５６および第１立壁部の終端部５２は、間隔を空けて対向しており、両者の間に洗い場床８からの導水路が形成される。 The standing wall portion 5 is formed in an arc shape along the upper edge portion 10 so as to rise from the upper edge portion 10, and is composed of two rotating first standing wall portions 50 and a second standing wall portion 55. The introduction end 51 of the first standing wall 50 and the end 57 of the second standing wall 50 face each other with a gap, and a headrace from the washing floor 8 is formed between them. Similarly, the introduction end portion 56 of the second standing wall portion 55 and the end portion 52 of the first standing wall portion face each other with a gap, and a headrace from the washing place floor 8 is formed between them.

立壁部５における導入端部５１および５６は、水切り部１の内側へ延びるように設けられている。導入端部５１および５６は、水切り部１の下方向に向かうにつれて、周方向の一側へ延びるように傾斜している。導入端部５１および５６は、水切り部１の下方向に向かうにつれて、上方から見て時計まわりの方向へ延びるように傾斜している。 The introduction ends 51 and 56 of the vertical wall portion 5 are provided so as to extend inward of the draining portion 1. The introduction ends 51 and 56 are inclined so as to extend unilaterally in the circumferential direction toward the downward direction of the draining portion 1. The introduction ends 51 and 56 are inclined so as to extend clockwise when viewed from above as the draining portion 1 is directed downward.

立壁部５における導入端部５１と終端部５７との間において、上縁部１０から貯水部２へ延びる導水面６が形成されている。また同様に導入端部５６と終端部５２との間において、上縁部１０から貯水部２へ延びる導水面６が形成されている。導水面６は、下方向に向かうにつれて、周方向の一側へ延びるように傾斜している。導水面６は、導入端部５１および５６と同様に、水切り部１の下方向に向かうにつれて、上方から見て時計まわり方向へ延びるように傾斜している。尚、図３に示す水切り部１では導水面６に通流孔４が設けられていないが、疎らに通流孔４を設けるようにしてもよい。 A water guide surface 6 extending from the upper edge portion 10 to the water storage portion 2 is formed between the introduction end portion 51 and the end portion 57 of the vertical wall portion 5. Similarly, a water guide surface 6 extending from the upper edge portion 10 to the water storage portion 2 is formed between the introduction end portion 56 and the end portion 52. The water guide surface 6 is inclined so as to extend to one side in the circumferential direction as it goes downward. Like the introduction ends 51 and 56, the water guiding surface 6 is inclined so as to extend clockwise when viewed from above as the draining portion 1 goes downward. Although the draining portion 1 shown in FIG. 3 is not provided with the flow hole 4 on the water guiding surface 6, the drain hole 4 may be provided sparsely.

導水面６は、立壁部５において発生させる旋回流の旋回方向へ向かって延びるように設けられている。したがって、ヘアキャッチャー１００に立壁部５が設けられておらず、ヘアキャッチャー１００の上縁部１０に至るまでに、流れ込む水に旋回流を発生させるような場合にも、導水面６は、該旋回流の旋回方向へ向かって延びるように設けるとよい。例えば、図２に示した蓋体８２の裏側やフランジ部８０等に流れの方向を規制する部分を設け、ヘアキャッチャー１００に流れ込む水に方向性を与えて旋回流が発生するようにできる。 The water guide surface 6 is provided so as to extend in the swirling direction of the swirling flow generated in the vertical wall portion 5. Therefore, even when the hair catcher 100 is not provided with the vertical wall portion 5 and a swirling flow is generated in the flowing water up to the upper edge portion 10 of the hair catcher 100, the water guide surface 6 swirls. It is preferable to provide it so as to extend in the swirling direction of the flow. For example, a portion that regulates the flow direction can be provided on the back side of the lid 82 or the flange portion 80 shown in FIG. 2 to give directionality to the water flowing into the hair catcher 100 so that a swirling flow is generated.

図４を参照する。導水面６は、上縁部１０から貯水部２へ延びて側面部２２の上端部である接続部分Ｔで側面部２２の内側面２２ａに接続される。側面部２２の内側面２２ａのうち接続部分Ｔの直下部分である内側面２２ａの上部２２ｂの勾配は、接続部分Ｔの直上部分である導水面６の下部６２の勾配と同じとしてある。これは、接続部分Ｔに上側から近づいたときの勾配と下側から近づいたときの勾配が同じであるという意味である。 See FIG. The water guide surface 6 extends from the upper edge portion 10 to the water storage portion 2 and is connected to the inner side surface 22a of the side surface portion 22 by a connecting portion T which is an upper end portion of the side surface portion 22. Of the inner side surface 22a of the side surface portion 22, the slope of the upper portion 22b of the inner side surface 22a, which is a portion directly below the connecting portion T, is the same as the slope of the lower portion 62 of the water guiding surface 6 which is a portion directly above the connecting portion T. This means that the gradient when approaching the connecting portion T from above and the gradient when approaching from below are the same.

本実施形態では、導水面６および内側面２２ａは、上縁部１０から底部２０にかけて下方に向かう勾配が一定であり、図４に示すように断面に現れる内側面の交線Ｍは直線となっている。 In the present embodiment, the water guiding surface 6 and the inner side surface 22a have a constant downward gradient from the upper edge portion 10 to the bottom portion 20, and the line of intersection M of the inner surface appearing in the cross section as shown in FIG. 4 is a straight line. ing.

次に実施形態に係るヘアキャッチャー１００の動作について説明する。ヘアキャッチャー１００の上縁部１０から水切り部１の上部に流れ込んだ水は、導水面６に沿ってヘアキャッチャー１００の内側を流下し、図３に矢印で示すように旋回流を発生する。水切り部１の内側を流下する水は、その一部が図３に矢印Ｑ１で示すように通流孔４を通して水切り部１の外側に排水される。水切り部１の内側を流下する水は、通流孔４に設けられた排水抵抗部４２によって排水が制限されるため、矢印Ｑ２で示すように水切り部１の内側に留まって流下することで、旋回流が発生し易くなる。 Next, the operation of the hair catcher 100 according to the embodiment will be described. The water that has flowed from the upper edge portion 10 of the hair catcher 100 to the upper part of the draining portion 1 flows down the inside of the hair catcher 100 along the water guiding surface 6 and generates a swirling flow as shown by an arrow in FIG. A part of the water flowing down the inside of the draining portion 1 is drained to the outside of the draining portion 1 through the through hole 4 as shown by the arrow Q1 in FIG. Since the drainage of the water flowing down the inside of the drainer portion 1 is restricted by the drainage resistance portion 42 provided in the flow hole 4, the water stays inside the drainer portion 1 and flows down as shown by the arrow Q2. Swirling flow is likely to occur.

排水抵抗部４２は、通流孔４の開口部４１のうち、水が流れ込む方向の先にある縦リブ３１における縁部４１ａの側において、周方向に通流孔４の中央へ張り出すように設けられている。このため、水切り部１の内側を流下する水が排水抵抗部４２に当たって水切り部１の内側に戻され易くなる。 The drainage resistance portion 42 projects in the circumferential direction toward the center of the flow hole 4 on the side of the edge portion 41a of the vertical rib 31 located at the tip of the opening 41 of the flow hole 4 in the direction in which water flows. It is provided. Therefore, the water flowing down the inside of the draining portion 1 hits the drainage resistance portion 42 and is easily returned to the inside of the draining portion 1.

導水面６は、下降するにつれて旋回流の旋回方向へ延びていることから旋回流が発生し易くなる。図４に示すように接続部分Ｔの直下部分である内側面２２ａの上部２２ｂの勾配は、接続部分Ｔの直上部分である導水面６の下部６２の勾配と同じであり、水流がスムーズに導水面６から貯水部２へ流れるので旋回流が発生し易くなる。また、本実施形態では、導水面６および内側面２２ａは、上縁部１０から底部２０にかけて下方に向かう勾配が一定であり、上縁部１０から底部２０にかけて水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 Since the water guide surface 6 extends in the swirling direction of the swirling flow as it descends, a swirling flow is likely to occur. As shown in FIG. 4, the gradient of the upper portion 22b of the inner side surface 22a, which is a portion directly below the connecting portion T, is the same as the gradient of the lower portion 62 of the water guiding surface 6 which is a portion directly above the connecting portion T, and the water flow is smoothly guided. Since it flows from the water surface 6 to the water storage unit 2, a swirling flow is likely to occur. Further, in the present embodiment, the water guiding surface 6 and the inner side surface 22a have a constant downward gradient from the upper edge portion 10 to the bottom portion 20, the turbulence of the water flow is suppressed from the upper edge portion 10 to the bottom portion 20, and the hair and the like. Is smoothly carried to the water storage section 2.

ヘアキャッチャー１００は、水切り部１の内側において旋回流が発生することで、髪の毛等を貯水部２にまとめ、清掃が容易になる。貯水部２には、水抜き孔２１が設けられている。旋回流発生時には水の一部が水抜き孔２１から抜けつつも貯水部２に水が貯まった状態となり、水の流れ込みが止んだ後、貯水部２に貯まった水が時間経過とともに水抜き孔２１から排水される。 In the hair catcher 100, a swirling flow is generated inside the draining portion 1, so that the hair and the like are gathered in the water storage portion 2 and cleaning becomes easy. The water storage unit 2 is provided with a drain hole 21. When a swirling flow occurs, a part of the water escapes from the drain hole 21, but the water is stored in the water storage section 2. After the water flow stops, the water stored in the water storage section 2 is drained over time. It is drained from 21.

（変形例）
図５を参照する。この変形例に係るヘアキャッチャー１００は、導水面６が上縁部１０から直下方向へ延びて貯水部２へ接続される。導水面６を通って流下した水は、例えば貯水部２において底部２０を通過した後、貯水部２の側面部２２で上昇し、水平軸まわりに旋回して戻るような水流となる。 (Modification example)
See FIG. In the hair catcher 100 according to this modification, the water guide surface 6 extends from the upper edge portion 10 in the direction directly downward and is connected to the water storage portion 2. The water flowing down through the water guide surface 6 passes through the bottom 20 in the water storage unit 2, then rises at the side surface 22 of the water storage unit 2, and becomes a water flow that swirls and returns around the horizontal axis.

導水面６と貯水部２の下方に向かう勾配は、上述の実施形態において図４に基づき説明した勾配と同様に一定であり、水が導水面６から貯水部２へとスムーズに流れ落ち、上述のように旋回する水流が発生し易くなる。 The downward slope of the water guide surface 6 and the water storage unit 2 is constant as in the gradient described with reference to FIG. 4 in the above embodiment, and water smoothly flows down from the water guide surface 6 to the water storage unit 2 as described above. A water flow that swirls like this is likely to occur.

図６（ａ）および図６（ｂ）を参照する。図６（ａ）に示すヘアキャッチャー１００は、接続部分Ｔの直下の内側面２２ａにおける下方に向かう勾配は、接続部分Ｔの直上の導水面６における下方に向かう勾配と同じとしてある。上述の実施形態と同様に、接続部分Ｔに上側から近づいたときの勾配と下側から近づいたときの勾配が同じであるという意味である。 See FIGS. 6 (a) and 6 (b). In the hair catcher 100 shown in FIG. 6A, the downward slope of the inner surface 22a directly below the connecting portion T is the same as the downward slope of the water guiding surface 6 directly above the connecting portion T. Similar to the above-described embodiment, it means that the gradient when approaching the connecting portion T from above and the gradient when approaching from below are the same.

導水面６および側面部２２の内側面２２ａは、交線Ｍで示すように、上縁部１０から底部２０にかけて内側に対して凹状に湾曲している。導水面６および内側面２２ａは、接続部分Ｔにおいて屈曲することなく滑らかに接続されており、水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 As shown by the line of intersection M, the water guide surface 6 and the inner side surface 22a of the side surface portion 22 are curved inwardly from the upper edge portion 10 to the bottom portion 20. The water guide surface 6 and the inner side surface 22a are smoothly connected without bending at the connecting portion T, turbulence of the water flow is suppressed, and hair and the like are smoothly carried to the water storage portion 2.

図６（ｂ）に示すヘアキャッチャー１００も、接続部分Ｔの直下の内側面２２ａにおける下方に向かう勾配は、接続部分Ｔの直上の導水面６における下方に向かう勾配と同じとしてある。導水面６および側面部２２の内側面２２ａは、交線Ｍで示すように、上縁部１０から底部２０にかけて内側に対して凹状に湾曲している。導水面６および内側面２２ａは、接続部分Ｔにおいて屈曲することなく滑らかに接続されており、水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 In the hair catcher 100 shown in FIG. 6B, the downward slope of the inner surface 22a directly below the connecting portion T is the same as the downward slope of the water guiding surface 6 directly above the connecting portion T. As shown by the line of intersection M, the water guide surface 6 and the inner side surface 22a of the side surface portion 22 are curved inwardly from the upper edge portion 10 to the bottom portion 20. The water guide surface 6 and the inner side surface 22a are smoothly connected without bending at the connecting portion T, turbulence of the water flow is suppressed, and hair and the like are smoothly carried to the water storage portion 2.

本発明の各実施形態および変形例のヘアキャッチャー１００は、水を通流させる水切り部１を備える。水切り部１は、底部２０と底部２０を囲む側面部２２とで形成される貯水部２、および上縁部１０から延びて側面部２２に接続される導水面６を有する。導水面６および側面部２２の接続部分Ｔにおける導水面６と側面部２２側の内側面２２ａの勾配が同じである。これにより、ヘアキャッチャー１００は、流れ込んだ水による旋回流が発生し易くなる。 Next, the features of the hair catcher 100 of the embodiment and the modified example will be described.
The hair catcher 100 of each embodiment and modification of the present invention includes a draining portion 1 for allowing water to flow through. The draining portion 1 has a water storage portion 2 formed by a bottom portion 20 and a side surface portion 22 surrounding the bottom portion 20, and a water guiding surface 6 extending from the upper edge portion 10 and connected to the side surface portion 22. The slopes of the water guide surface 6 and the inner side surface 22a on the side surface 22 side at the connection portion T of the water guide surface 6 and the side surface portion 22 are the same. As a result, the hair catcher 100 is likely to generate a swirling flow due to the flowing water.

また導水面６および内側面２２ａの勾配が一定である。これにより、ヘアキャッチャー１００は、水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 Further, the gradients of the water guiding surface 6 and the inner surface 22a are constant. As a result, the hair catcher 100 suppresses the turbulence of the water flow, and the hair and the like are smoothly carried to the water storage unit 2.

また導水面６および内側面２２ａは、上縁部１０から底部２０にかけて内側に対して凹状に湾曲している。これにより、ヘアキャッチャー１００は、水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 Further, the water guide surface 6 and the inner side surface 22a are curved in a concave shape from the upper edge portion 10 to the bottom portion 20. As a result, the hair catcher 100 suppresses the turbulence of the water flow, and the hair and the like are smoothly carried to the water storage unit 2.

また導水面６および内側面２２ａは、上縁部１０から底部２０にかけて内側に対して凸状に湾曲している。これにより、ヘアキャッチャー１００は、水流の乱れが抑制され、髪の毛等がスムーズに貯水部２へ運ばれる。 Further, the water guide surface 6 and the inner side surface 22a are curved inwardly from the upper edge portion 10 to the bottom portion 20. As a result, the hair catcher 100 suppresses the turbulence of the water flow, and the hair and the like are smoothly carried to the water storage unit 2.

また導水面６は、水切り部１の内側に発生する旋回流の旋回方向に、上縁部１０から延びるように形成されている。これにより、ヘアキャッチャー１００は、旋回流が発生し易くなる。 Further, the water guiding surface 6 is formed so as to extend from the upper edge portion 10 in the swirling direction of the swirling flow generated inside the draining portion 1. As a result, the hair catcher 100 is likely to generate a swirling flow.
