Description

本発明は、排水トラップに設けられるヘアキャッチャーに関する。 The present invention relates to a hair catcher provided in a drain trap.

浴室の排水トラップには、毛髪を主とするごみ等の異物を排水中から捕集するヘアキャッチャーが着脱可能に設けられている。また、ヘアキャッチャー外で発生させた渦流をヘアキャッチャー内に導入して異物をまとめるようにすることも行われている。 The bathroom drain trap is detachably provided with a hair catcher that collects foreign matters such as dust, mainly hair, from the drain. In addition, eddy currents generated outside the hair catcher are introduced into the hair catcher to collect foreign substances.

特許文献１には、漏斗型封水筒に設置する深型ヘアキャッチャー内に渦巻き水流を発生させる様に深型ヘアキャッチャーの外側に水向案内部を設けた排水口が記載されている。図８の（ａ）は漏斗型封水筒９０２及び水向案内部９０３を断面視して同文献に記載された排水口を示す側面図であり、同図（ｂ）は水向案内部９１３を一体化したヘアキャッチャー９１１を示す側面図であり、同図（ｃ）は漏斗型封水筒９０２及び水向案内部９１８を断面視して同文献に記載された排水口を示す側面図である。
同図（ａ）の排水口は、封水筒９０２に排水量調節部品９０４を取り付けて封水筒９０２の穴径を小さくすることにより、水向案内部９０３による右回転の渦巻き水流を封水筒９０２内、すなわち、ヘアキャッチャー９０１外で発生させている。これにより、ヘアキャッチャー９０１内に渦巻き水流が発生するとされている。同排水口は、洗い場からの排水がヘアキャッチャー９０１全体に流入し、全排水が排水量調節部品９０４を通って少しずつ流下することになる。
また、同図（ｂ）の排水口は、ヘアキャッチャー９１１の外側面に水向案内部９１３を一体形成あるいは着脱可能に形成している。同排水口も、水向案内部９１３による右回転の渦巻き水流をヘアキャッチャー９１１外で発生させ、この渦巻き水流をヘアキャッチャー９１１内に導入している。
さらに、同図（ｃ）の排水口は、ヘアキャッチャー９１６の上部位置に水向案内部９１８を配置している。 Patent Document 1 describes a drain outlet provided with a water direction guide portion on the outside of a deep hair catcher so as to generate a swirling water flow in a deep hair catcher installed in a funnel-type sealed water tube. (A) of FIG. 8 is a side view showing a drain outlet described in the same document in a cross-sectional view of the funnel-type sealing cylinder 902 and the water direction guide portion 903, and FIG. It is a side view which shows the integrated hair catcher 911, and the same figure (c) is a side view which shows the drain outlet described in the literature by carrying out the cross sectional view of the funnel type sealing cylinder 902 and the water direction guide part 918.
The drain outlet of FIG. 6A is provided with a drainage amount adjusting component 904 attached to the sealing cylinder 902 to reduce the hole diameter of the sealing cylinder 902 so that the swirling water flow rotated clockwise by the water direction guide portion 903 is contained in the sealing cylinder 902. That is, it is generated outside the hair catcher 901. Thereby, it is supposed that a swirling water flow is generated in the hair catcher 901. In the drainage outlet, the wastewater from the washing place flows into the entire hair catcher 901, and the whole wastewater flows down little by little through the drainage amount adjusting component 904.
Moreover, the drain outlet of the same figure (b) forms the water direction guide part 913 in the outer surface of the hair catcher 911 so that it can form integrally or detachably. The drain outlet also generates a swirling water flow rotated clockwise by the water direction guide portion 913 outside the hair catcher 911 and introduces the swirling water flow into the hair catcher 911.
Furthermore, the water outlet guide 918 is arrange | positioned in the upper position of the hair catcher 916 at the drain outlet of the same figure (c).

特許文献２には、排水桝の立面に設けた吐水口から浴槽排水を吐出するようにした排水構造が記載されている。図８（ｄ）は、同文献に記載された排水構造を示す斜視図である。この排水構造は、排水桝９２３の底面９２３ａの流入口９２４に対してヘアキャッチャー９２５が水平に取り付けられ、吐水口９２１からの浴槽排水の吐出方向が流入口９２４の中心を向いていない。このため、吐水口９２１から吐出された浴槽排水は、渦を描いて流入口９２４へ向かい、ヘアキャッチャー９２５を通過する。 Patent Document 2 describes a drainage structure in which bathtub drainage is discharged from a spout provided on an elevation surface of a drainage basin. FIG.8 (d) is a perspective view which shows the drainage structure described in the literature. In this drainage structure, the hair catcher 925 is attached horizontally to the inlet 924 of the bottom surface 923 a of the drainage basin 923, and the discharge direction of the bathtub drainage from the water outlet 921 does not face the center of the inlet 924. For this reason, the bathtub drainage discharged from the water discharge port 921 draws a vortex toward the inflow port 924 and passes through the hair catcher 925.

特許文献３には、キッチンのシンクに設けられた排水トラップが記載されている。図８（ｅ）は、同文献に記載された排水トラップ９３０を示す垂直断面図である。排水トラップ９３０は、水受椀部９３１ａや封水椀部９３１ｂや外周流路部９３１ｃを有するトラップ本体９３１、封水椀部９３１ｂ内に挿入された防臭筒９３２、水受椀部９３１ａ内に配置された網かご９３３、水受椀部９３１ａの上面開口を蓋う蓋体９３４、を備えている。外周流路部９３１ｃや防臭筒９３２や蓋体９３４には、封水椀部９３１ｂ内で一方向に回転する渦流が水流により発生するように排水を案内する排水案内手段が設けられている。シンクから排水トラップ９３０へ流れる排水は、封水椀部９３１ｂ内で渦流が発生するように蓋体９３４で案内され、網かご９３３を通過する。
特開２００７−１９８１３０号公報特開２００７−４６４２４号公報特開２００７−１２００２１号公報 Patent Document 3 describes a drain trap provided in a kitchen sink. FIG. 8E is a vertical sectional view showing the drain trap 930 described in the document. The drain trap 930 is disposed in the trap body 931 having the water catching portion 931a, the sealed water catching portion 931b, and the outer peripheral flow passage portion 931c, the deodorizing cylinder 932 inserted in the sealed water catching portion 931b, and the water catching portion 931a. And a lid 934 that covers the upper surface opening of the water catcher 931a. The outer peripheral flow path portion 931c, the deodorizing cylinder 932, and the lid body 934 are provided with drainage guide means for guiding drainage so that a vortex that rotates in one direction in the sealed water bottle portion 931b is generated by the water flow. The drainage flowing from the sink to the drain trap 930 is guided by the lid 934 so as to generate a vortex in the sealed water trough 931b and passes through the mesh basket 933.

図８（ａ）に示す排水口は、洗い場からの排水が全て排水量調節部品９０４を通過するため、排水能力が制限される。このため、同排水口は、浴槽から湯が溢れたとき等、一度に大量の排水が生じたときに十分に排出されないことがある。同図（ｂ）（ｃ）に示すヘアキャッチャー９１１を排水口に用いても、同様である。
また、同図（ａ）（ｂ）に示すヘアキャッチャー９０１，９１１は、外側に水向案内部９０３，９１３が設けられているため、封水筒９０２内で渦巻き水流を発生させるためには封水筒９０２の形状を水向案内部９０３，９１３の形状に合わせなければならない。
さらに、同図（ａ）〜（ｃ）に示すヘアキャッチャー９０１，９１１，９１６は、洗い場からの全排水がヘアキャッチャー全体に流入するため、ヘアキャッチャー全体に毛髪等が付着し、ヘアキャッチャーから毛髪等を除去し難かったり、ヘアキャッチャーが目詰まりしたりすることがある。 The drain outlet shown in FIG. 8 (a) has a limited drainage capacity because all the drainage from the washing place passes through the drainage amount adjustment component 904. For this reason, the drain outlet may not be sufficiently discharged when a large amount of drainage occurs at one time, such as when hot water overflows from the bathtub. The same applies when the hair catcher 911 shown in FIGS.
Further, since the hair catchers 901 and 911 shown in FIGS. 5A and 5B are provided with water direction guide portions 903 and 913 on the outer side, a sealed water tube is required to generate a spiral water flow in the sealed water tube 902. The shape of 902 must be matched to the shape of the water direction guides 903 and 913.
Furthermore, in the hair catchers 901, 911, and 916 shown in FIGS. 9A to 9C, since all drainage from the washing area flows into the entire hair catcher, the hair or the like adheres to the entire hair catcher, and the hair catcher moves from the hair catcher to the hair. Etc. may be difficult to remove, or the hair catcher may be clogged.

図８（ｄ）に示す排水構造は、渦流を発生させるために浴槽排水が必要であり、かつ、浴槽排水を吐出する吐水口９２１を排水桝９２３に形成する必要がある。また、ヘアキャッチャー９２５が水平に配置され、排水がヘアキャッチャー９２５上で保水されず速やかにヘアキャッチャー９２５全体を通過するようにされているため、毛髪等がヘアキャッチャー全体に絡み付きやすい。このため、ヘアキャッチャーから毛髪等を除去し難かったり、ヘアキャッチャーが目詰まりしたりすることがある。 The drainage structure shown in FIG. 8D requires bathtub drainage in order to generate eddy currents, and it is necessary to form a water discharge port 921 for discharging bathtub drainage in the drainage 923. Moreover, since the hair catcher 925 is arranged horizontally and the drainage is not retained on the hair catcher 925 so that the hair catcher 925 passes through the entire hair catcher 925 quickly, the hair or the like is easily entangled with the entire hair catcher. For this reason, it may be difficult to remove hair or the like from the hair catcher, or the hair catcher may be clogged.

図８（ｅ）に示す排水トラップ９３０は、浴室ではなくキッチンに設けられるため、ヘアキャッチャーではなく網かご９３３を用いている。また、排水が網かご９３３内で保水されず速やかに網かご９３３全体を通過するようにされているため、仮に毛髪等が流された場合には、その毛髪等が網かご全体に絡み付きやすい。このため、網かごから毛髪等を除去し難かったり、網かごが目詰まりしたりすることがある。 Since the drain trap 930 shown in FIG. 8 (e) is provided not in the bathroom but in the kitchen, a net basket 933 is used instead of a hair catcher. Further, since the drainage is not retained in the mesh basket 933 and passes through the mesh basket 933 promptly, if hair or the like is shed, the hair or the like is easily entangled with the entire mesh basket. For this reason, it may be difficult to remove hair from the mesh basket, or the mesh basket may be clogged.

本発明は、上記課題に鑑みてなされたもので、ヘアキャッチャーを設ける排水トラップに特別な構造を設ける必要が無く、捕集した毛髪等を容易に除去することができ、安定した排水能力を得ることが可能なヘアキャッチャーの提供を目的とする。 The present invention has been made in view of the above problems, and it is not necessary to provide a special structure for a drain trap provided with a hair catcher, and the collected hair and the like can be easily removed, thereby obtaining a stable drainage capability. The purpose is to provide a hair catcher that can do this.

上記目的を達成するため、本発明は、排水トラップに設けられるヘアキャッチャーであって、底部に上方へ凸とされた凸部を有する凹状とされ、流入した排水を保水する保水部と、該保水部の上部から延出し、排水中の毛髪の流出を抑止しながら前記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、前記保水部内における前記凸部の最上部から水平方向へずれた位置に向けて洗い場からの排水を前記保水部へ導く排水導入部とを備えることを特徴とする。 In order to achieve the above object, the present invention provides a hair catcher provided in a drain trap, which is a concave shape having a convex portion that is convex upward at the bottom, and a water retention portion that retains the drained water, and the water retention An upper drainage outflow part that extends from the top of the part and prevents the hair from flowing into the drainage while preventing the drainage from entering the water retaining part, and shifted from the top of the convex part in the water retaining part in the horizontal direction. A drainage introduction part that guides drainage from the washing area to the water retention part toward the position is provided.

すなわち、洗い場からの排水は、排水導入部により保水部内における凸部の最上部から水平方向へずれた位置に向かって凹状の保水部へ導かれ、該保水部で保水される。また、保水部に入りきらない排水は、保水部の上部から延出した上部排水流出部から流出する。ここで、保水部に入りきらない排水は、単に上部排水流出部からオーバーフローする訳ではなく、毛髪の流出が抑止されながら上部排水流出部から流出する。
保水部内に溜まった排水の中では、毛髪等が浮遊して集まり、毛髪等が集まった状態で保水部内に残存する。また、凹状の保水部へ導かれる排水が凸部の最上部から水平方向へずれた位置に向かうことにより保水部内で排水の旋回流が生じ易く、保水部内に凸部があることにより保水部へ導かれる排水が旋回流を打ち消す方向へ流入し難いので、保水部内で毛髪等がまとまり易い。従って、捕集した毛髪等を容易に除去することができる性能、すなわち、良好な毛髪除去性を得ることができる。
また、洗い場からの排水が保水部へ導かれるので、上部排水流出部の閉塞が抑止される。従って、安定した排水能力を得ることができる。
さらに、上述した良好な毛髪除去性及び安定した排水能力は、ヘアキャッチャー単独の構造のみで得られる。 That is, the waste water from the washing place is guided to the concave water retaining portion toward the position shifted in the horizontal direction from the uppermost portion of the convex portion in the water retaining portion by the drain introduction portion, and is retained in the water retaining portion. Further, the wastewater that cannot enter the water retaining portion flows out from the upper drainage outflow portion extending from the upper portion of the water retaining portion. Here, the wastewater that does not enter the water retaining portion does not simply overflow from the upper drainage outflow portion, but flows out from the upper drainage outflow portion while suppressing the outflow of hair.
In the drainage accumulated in the water retention part, hair and the like float and gather, and the hair and the like remain in the water retention part in a collected state. In addition, the drainage led to the concave water retention part is directed to a position shifted in the horizontal direction from the uppermost part of the convex part, so that a swirling flow of the drainage easily occurs in the water retention part, and the convex part in the water retention part causes the water retention part. Since the drained water that is guided does not easily flow in a direction that cancels the swirling flow, hair or the like is easily collected in the water retaining portion. Therefore, it is possible to obtain performance that can easily remove the collected hair, that is, good hair removability.
Moreover, since the waste water from a washing place is guide | induced to a water holding part, obstruction | occlusion of an upper drainage outflow part is suppressed. Therefore, a stable drainage capacity can be obtained.
Furthermore, the above-described good hair removability and stable drainage ability can be obtained only by the structure of the hair catcher alone.

各請求項に係る発明において、上記ヘアキャッチャーには、毛髪以外の異物も捕集するものも含まれる。また、上記ヘアキャッチャーには、浴室の排水トラップに用いられるヘアキャッチャーの他、洗面化粧台の排水トラップに用いられるヘアキャッチャー、理容店や美容室の排水トラップに用いられるヘアキャッチャー、等も含まれる。
上記排水は、毛髪を含む水とする。
洗い場からの排水には、洗い場から排水桝内に落ちた後にヘアキャッチャー内へ流れ込む排水が含まれる。
上記凸部の凸とされた形状には、膨出した形状や突出した形状等が含まれる。
排水中の毛髪の流出を抑止する上記上部排水流出部は、全ての毛髪を止めなくても良い。すなわち、抑止は、全てを止めることに限定されない。
上記保水部が排水を保水することには、排水を一時的に保水することが含まれる。ここで、保水部が排水を一時的に保水することは、保水部内で排水が流出しながらも一時的に排水が溜まった状態にさせることを意味する。
上記凹状の保水部は排水を受けて保水する形状であればよく、該保水部の形状には椀状、半球状、上下逆の円錐状、上下逆の角錐状、等の底部に上方へ凸とされた凸部を有する形状が含まれる。 In the invention according to each claim, the hair catcher includes one that collects foreign matters other than hair. In addition to the hair catcher used for the bathroom drain trap, the hair catcher includes a hair catcher used for a bathroom trap drainage trap, a hair catcher used for a barber shop or beauty salon drain trap, and the like. .
The drainage is water containing hair.
Drainage from the washroom includes drainage that flows from the washroom into the drainage basin and then into the hair catcher.
The convex shape of the convex portion includes a bulging shape, a protruding shape, and the like.
The upper drainage outflow part that suppresses the outflow of hair during drainage does not have to stop all hair. That is, deterrence is not limited to stopping everything.
The holding of the drainage by the water retention unit includes temporarily holding the drainage. Here, the fact that the water retention unit temporarily retains the drainage means that the drainage is temporarily accumulated while the drainage flows out in the water retention unit.
The concave water retaining portion may have any shape that receives drainage and retains water. The shape of the water retaining portion protrudes upward at the bottom, such as a bowl shape, a hemispherical shape, an upside down conical shape, and an upside down pyramid shape. A shape having a convex portion is included.

また、前記上部排水流出部は、前記保水部に入りきらない排水を流出させる孔を有し、前記排水導入部は、前記上部排水流出部の外縁と前記保水部の上部とを繋ぐとともに前記上部排水流出部の孔同士で挟まれた位置で洗い場からの排水を前記保水部へ通す流入部と、該流入部へ洗い場からの排水を通す流入口を設けて前記孔が存在する前記上部排水流出部の外側に配置されるとともに前記流入部上の排水が前記保水部内における前記凸部の最上部から水平方向へずれた位置に向かうように前記流入口側の縁部が前記保水部の方へ曲げられた立壁部とを有してもよい。
すなわち、ヘアキャッチャーに流入する洗い場からの排水は、立壁部により上部排水流出部の孔へ流入し難くされ、流入口から流入部を通って保水部内における凸部の最上部から水平方向へずれた位置に向かい、該保水部で保水される。 Further, the upper drainage outflow portion has a hole through which drainage that does not enter the water retaining portion flows out, and the drainage introduction portion connects the outer edge of the upper drainage outflow portion and the upper portion of the water retention portion and the upper portion. The upper drainage outflow where the hole exists by providing an inflow part for passing the wastewater from the washing place to the water retaining part at a position sandwiched between the holes of the drainage outflow part, and an inlet for passing the drainage from the washing place to the inflow part And the edge on the inlet side toward the water retaining portion so that the drainage on the inflow portion is directed to a position shifted in the horizontal direction from the top of the convex portion in the water retaining portion. You may have a bent standing wall part.
That is, the drainage from the washing place flowing into the hair catcher is made difficult to flow into the hole of the upper drainage outflow part by the standing wall part, and is shifted in the horizontal direction from the uppermost part of the convex part in the water retaining part through the inflow part from the inflow port. Headed to the position, the water is retained in the water retaining section.

さらに、前記保水部は、排水中の毛髪の流出を抑止しながら排水を流出させる下部排水流出部を下部に有し、流入した排水を一時的に保水しながら該排水を前記下部排水流出部から流出させてもよい。
すなわち、保水部内で一時的に溜まった排水の中では、毛髪等が浮遊して集まり、保水部から排水が抜けたときに毛髪等が集まった状態で保水部内に残存する。保水部の底部に凸部が設けられているので、集まった毛髪等が凸部に支えられ、該毛髪等と保水部底部との接触面積が減少し、毛髪等を捨てる際に保水部の内側面から毛髪等が離れやすい。 Further, the water retaining part has a lower drainage outflow part in the lower part for draining the wastewater while suppressing the outflow of hair in the drainage, and the drainage is temporarily retained from the lower drainage outflow part while retaining the drained water. It may be spilled.
That is, in the drainage water temporarily stored in the water retention unit, hairs and the like float and gather, and when the drainage drains from the water retention unit, the hairs and the like remain in the water retention unit. Since the convex part is provided at the bottom of the water retention part, the collected hair is supported by the convex part, the contact area between the hair and the bottom of the water retention part is reduced, and when the hair is discarded, Hair etc. are easily separated from the side.

なお、上記排水が毛髪を含む水であるので、下部排水流出部や上部排水流出部は、毛髪を含む水が流出する部位を意味する。排水中の毛髪の流出を抑止する上記下部排水流出部は、全ての毛髪を止めなくても良い。
上記保水部が排水を一時的に保水することは、保水部内で排水が流出しながらも一時的に排水が溜まった状態にさせることを意味する。従って、保水部内での排水の滞留時間は、有限の時間である。中で毛髪が浮遊しながら保水部内に存在する排水の状態は、保水部内に一時的に保水されている状態に含まれる。 In addition, since the said waste_water | drain is water containing hair, a lower drainage outflow part and an upper drainage outflow part mean the site | part through which the water containing hair flows out. The lower drainage outflow part for suppressing the outflow of hair during drainage does not have to stop all the hair.
The fact that the water retaining part temporarily retains the drainage means that the drainage is temporarily accumulated while the drainage flows out in the water retaining part. Therefore, the residence time of the waste water in the water retention unit is a finite time. The state of the waste water that is present in the water retaining portion while the hair is floating therein is included in the state in which the water is temporarily retained in the water retaining portion.

保水部内の排水の旋回流は保水部内に存在する排水が回転する流れをいい、保水部に流入した排水が下部排水流出部等から流出するまでの回転数に制限は無い。また、旋回流の仮想の回転軸の向きは、鉛直方向でもよいし、水平方向でもよいし、鉛直方向や水平方向から斜めにずれた方向でもよい。 The swirling flow of the drainage water in the water retention part refers to the flow of the wastewater existing in the water retention part rotating, and there is no restriction on the number of revolutions until the wastewater flowing into the water retention part flows out from the lower drainage outflow part or the like. Further, the direction of the virtual rotation axis of the swirl flow may be the vertical direction, the horizontal direction, or a direction that is obliquely deviated from the vertical direction or the horizontal direction.

なお、上記ヘアキャッチャーを有する排水トラップの発明や、上記ヘアキャッチャーを有する浴室の発明も、上述した作用、効果を奏する。 The invention of the drain trap having the hair catcher and the invention of the bathroom having the hair catcher also have the above-described actions and effects.

請求項１に係る発明によれば、ヘアキャッチャーを設ける排水トラップに特別な構造を設ける必要が無く、良好な毛髪除去性及び安定した排水能力を得ることが可能なヘアキャッチャーを提供することができる。
請求項２に係る発明では、洗い場からの排水が上部排水流出部へ流入し難いので、上部排水流出部の閉塞を抑止して安定した排水能力を得ることができる。
請求項３に係る発明では、毛髪等を捨て易くすることができる。 According to the first aspect of the present invention, there is no need to provide a special structure for the drain trap provided with the hair catcher, and a hair catcher capable of obtaining good hair removability and stable drainage capability can be provided. .
In the invention which concerns on Claim 2, since the waste_water | drain from a washing place does not flow easily into an upper drainage outflow part, obstruction | occlusion of an upper drainage outflow part can be suppressed and the stable drainage capability can be obtained.
In the invention which concerns on Claim 3, hair etc. can be made easy to throw away.

浴室は、図示しないシャワーや給湯栓等が設けられた洗い場Ｗ１が浴槽Ｂ１の外側に設けられ、この洗い場Ｗ１の床材１１０の一部が凹んで排水桝１１２が形成されている。この排水桝１１２は、下側の開口部に向かって略水平方向に内側へ延出したフランジ部１１３を有し、上側の開口部にカバー１２０を着脱することができるようにされている。排水トラップ１は、排水桝１１２に取り付けられ、カバー１２０と床材１１０との隙間ＣＬ１から排水桝１１２へ流入した排水を通過させる。本排水トラップ１は、カバー１２０、トラップ本体１３０、締め付けフランジ１４０、封水筒１５０、及びヘアキャッチャー１０を備える。
排水桝１１２の四隅には、図２に示すように、カバー１２０を載置するための洗い場側段部１１４ａ，１１４ａ及び浴槽側段部１１４ｂ，１１４ｂが形成されている。カバー１２０の浴槽側縁部１２０ａには、洗い場側へ凹んだ手かけ部１２２が形成されている。 In the bathroom, a washing place W1 provided with a shower, a hot water tap, etc. (not shown) is provided outside the bathtub B1, and a part of the floor material 110 of the washing place W1 is recessed to form a drainage tub 112. This drainage basin 112 has a flange 113 extending inward in a substantially horizontal direction toward the lower opening, and the cover 120 can be attached to and detached from the upper opening. The drainage trap 1 is attached to the drainage basin 112 and allows the drainage that has flowed into the drainage basin 112 from the gap CL1 between the cover 120 and the flooring 110 to pass therethrough. The drain trap 1 includes a cover 120, a trap body 130, a tightening flange 140, a water seal 150, and a hair catcher 10.

A protruding discharge port 132 is formed. The connection port 131 is connected to the waterproof pan of the bathtub through a connection pipe. In the trap body 130, a sealing surface S is formed at the upper edge of the side walls 130 a and 130 b, and the lower part of the sealing cylinder 150 is inserted below the sealing surface S. Further, a flange portion 133 extending radially inward is formed on the upper edge portion of the trap body 130, and a screw portion 133 a is formed on the inner peripheral surface of the flange portion 133.

締め付けフランジ１４０は、図１及び図３（ａ）に示すように、トラップ本体のねじ部１３３ａと螺合するねじ部１４１ａを外周面に有する円筒部１４１と、この円筒部１４１の上縁部で径方向外側へ延出した上側フランジ部１４２と、円筒部１４１の下縁部で径方向内側へ延出した下側フランジ部１４３とを備える略環状に形成されている。円筒部１４１の内周面には、９０°間隔で４箇所に上下２つの突起１４１ｂが形成されている。床材のフランジ部１１３の先端部にパッキン１４４を取り付け、このパッキン１４４をトラップ本体のフランジ部１３３とで挟むようにして該フランジ部１３３に締め付けフランジ１４０を螺入すると、床材のフランジ部１１３とトラップ本体１３０とを互いに固定することができる。 As shown in FIGS. 1 and 3A, the fastening flange 140 includes a cylindrical portion 141 having a screw portion 141a screwed with the screw portion 133a of the trap body on the outer peripheral surface, and an upper edge portion of the cylindrical portion 141. The upper flange portion 142 extending outward in the radial direction and the lower flange portion 143 extending inward in the radial direction at the lower edge portion of the cylindrical portion 141 are formed in a substantially annular shape. On the inner peripheral surface of the cylindrical portion 141, two upper and lower projections 141b are formed at four positions at intervals of 90 °. When the packing 144 is attached to the front end of the flange portion 113 of the floor material, and the fastening flange 140 is screwed into the flange portion 133 so that the packing 144 is sandwiched between the flange portion 133 of the trap body, the flange portion 113 of the floor material and the trap The main body 130 can be fixed to each other.

封水筒１５０は、図１及び図３（ｂ）に示すように、筒状の本体部１５１と、この本体部１５１の上縁部から径方向外側へ延出したフランジ部１５２とを有する形状に形成されている。フランジ部１５２の外縁部には、９０°間隔で４箇所に切欠１５２ａが形成されている。各切欠１５２ａを締め付けフランジの突起１４１ｂに合わせて締め付けフランジ１４０の開口部に封水筒の本体部１５１を挿入し、封水筒のフランジ部１５２を締め付けフランジの下側フランジ部１４３に接触させて回転させることにより、トラップ本体１３０内の所定位置に封水筒１５０が固定される。ここで、封水筒１５０の下端とトラップ本体１３０の底面との間に隙間が設けられている。 As shown in FIGS. 1 and 3B, the sealing cylinder 150 has a cylindrical main body portion 151 and a flange portion 152 that extends radially outward from the upper edge portion of the main body portion 151.

ヘアキャッチャー１０は、図４〜図７に示す一時保水部（保水部）２０と上部排水流出部３０と排水導入部４０を備え、排水から毛髪等のごみを捕集する。本ヘアキャッチャー１０は、凸部の最上部２４ａを通る鉛直線を中心として２回回転対称な形状とされている。なお、本明細書において、２回回転対称とは、一つの立体図形を一定軸のまわりに１８０°回転移動させて初めて同じ立体図形になる性質をいうものとする。 The hair catcher 10 includes a temporary water retention unit (water retention unit) 20, an upper drainage outflow unit 30, and a drainage introduction unit 40 illustrated in FIGS. 4 to 7, and collects dust such as hair from the drainage. The hair catcher 10 has a two-fold rotational symmetry about a vertical line passing through the uppermost portion 24a of the convex portion. In the present specification, the two-fold rotational symmetry refers to the property that a solid figure becomes the same solid figure only when it is rotated 180 degrees around a fixed axis.

一時保水部２０は、上部が開口し下方へ凹んだ凹状に形成され、流入した排水を保水する。本実施形態の一時保水部２０は、半球の底に上方へ凸とされた凸部２４を有する凹状とされている。凸部２４を含む一時保水部２０下部には、排水中の毛髪等の流出を抑止しながら排水を略下方へ流出させる水抜き孔２３が複数形成されている。これらの水抜き孔２３が設けられた一時保水部２０下部は、本発明にいう下部排水流出部２２となっている。排水を流出させる下部排水流出部２２が凹状の一時保水部２０の下部に存在することにより、一時保水部２０内で一時的に保水される排水に渦流が発生し易くなっている。
一方、一時保水部２０における下部排水流出部２２の周囲は、水抜き孔の無い壁部２１とされ、外側に向かって膨出しながら斜めに立ち上がっている。従って、一時保水部２０は、流入した排水を一時的に保水しながら該排水を下部排水流出部２２から流出させる。一時保水部が略半球状に形成されているので、一時保水部内で排水が旋回流になり易くなり、毛髪等をまとめて捨て易くすることができる。 The temporary water retaining portion 20 is formed in a concave shape that is open at the top and recessed downward, and retains the drained water that has flowed in. Temporary water retention part 20 of this embodiment is made into the concave shape which has convex part 24 projected on the bottom of the hemisphere. A plurality of drainage holes 23 are formed in the lower portion of the temporary water retaining portion 20 including the convex portion 24 to allow the drainage to flow out substantially downward while suppressing the outflow of hair or the like in the drainage. The lower part of the temporary water retaining part 20 provided with these drain holes 23 is a lower drainage outflow part 22 according to the present invention. Since the lower drainage outflow portion 22 for draining the drainage is present in the lower portion of the concave temporary water retaining portion 20, eddy current is easily generated in the wastewater temporarily retained in the temporary water retaining portion 20.
On the other hand, the periphery of the lower drainage outflow portion 22 in the temporary water retention portion 20 is a wall portion 21 without a drain hole, and rises obliquely while bulging outward. Therefore, the temporary water retention unit 20 causes the drainage to flow out from the lower drainage outflow unit 22 while temporarily retaining the inflowing wastewater. Since the temporary water-retaining part is formed in a substantially hemispherical shape, the drainage easily turns into a swirling flow in the temporary water-retaining part, and it is possible to make it easy to discard hair and the like together.

凸部２４は、最上部２４ａが一時保水部２０の上縁部２１ａよりも低くされ、一時保水部２０の底部から上方へなだらかに膨出している。本実施形態の水抜き孔２３は、凸部の最上部２４ａから一時保水部２０の最下部２０ａを越えて凸部２４の周囲にまで複数設けられている。ヘアキャッチャー１０が凸部の最上部２４ａを通る鉛直線を中心として２回回転対称であるので、図６に示すように仮想の水平面ＨＰ１に投影するとき、凸部の最上部２４ａは下部排水流出部２２の平面図形の重心ＣＥ１と一致する。
ここで、ヘアキャッチャー１０を仮想の水平面ＨＰ１に投影した平面図形は図５の平面図に相当し、下部排水流出部２２の平面図形（水抜き孔２３に相当する部分も含まれる）は同図の２２で表される二点鎖線で囲まれた図形に相当する。この平面図形は、水抜き孔２３に相当する部分を含むものとする。下部排水流出部２２の平面図形の重心ＣＥ１は、幾何学やシミュレーションで求めることができ、単位面積当たりの重量が均一な板を水抜き孔２３の無い下部排水流出部２２の形状に切り取って釣り合う点、すなわち、質量中心を探す試験を行うことによっても求めることができる。 The uppermost part 24 a of the convex part 24 is lower than the upper edge part 21 a of the temporary water retention part 20, and gently bulges upward from the bottom part of the temporary water retention part 20. A plurality of drain holes 23 in the present embodiment are provided from the uppermost part 24 a of the convex part to the lower part 20 a of the temporary water retaining part 20 to the periphery of the convex part 24. Since the hair catcher 10 is rotationally symmetrical twice about the vertical line passing through the top 24a of the convex portion, when projected onto the virtual horizontal plane HP1 as shown in FIG. It coincides with the center of gravity CE1 of the plane figure of the portion 22.
Here, the plan view of the hair catcher 10 projected onto the virtual horizontal plane HP1 corresponds to the plan view of FIG. 5, and the plan view of the lower drainage outflow portion 22 (including the portion corresponding to the drain hole 23) is shown in FIG. This corresponds to a figure surrounded by a two-dot chain line represented by. This plane figure includes a portion corresponding to the drain hole 23. The center of gravity CE1 of the plane figure of the lower drainage outflow portion 22 can be obtained by geometry or simulation, and a plate having a uniform weight per unit area is cut out to the shape of the lower drainage outflow portion 22 without the drain hole 23 and balanced. It can also be determined by performing a test to find the point, that is, the center of mass.

凸部２４と一時保水部壁部２１との水平方向の間は、人の指が入るような間隔が設けられている。これにより、ヘアキャッチャー１０を洗浄する際に一時保水部の最下部２０ａまで容易に洗浄することができる。 Between the horizontal direction of the convex part 24 and the temporary water retention part wall part 21, the space | interval which a human finger enters is provided. Thereby, when washing | cleaning the hair catcher 10, it can wash | clean to the lowest part 20a of a temporary water retention part easily.

下部排水流出部２２の最大の排水流出流量Qd（リットル／分）は、排水中の毛髪が浮遊する程度に洗い場Ｗ１からの排水が一時保水部２０内で一時的に溜まる流量が好ましい。ここで、最大の排水流出流量Qdは、一時保水部２０内に排水が上縁部２１ａまで溜まっているように連続して排水を導入したときに下部排水流出部２２から流出する排水の流出流量とする。また、洗い場で使用するシャワーの平均吐水流量Qs（リットル／分）よりもQdを小さくすると、平均的な吐水流量で洗い場のシャワーを使用したときに洗い場の排水が一時保水部２０内で一時的に溜まるので好ましい。一方、一時保水部２０で一時的に保水される排水の滞留時間Ｔを数秒〜十数秒程度（例えば５〜１５秒）とするようにQdを設定すると、洗い場使用後速やかに一時保水部２０から排水が抜けて毛髪等を除去する作業を行うことができるので好ましい。
なお、上記排水流出流量Qdを大きくするには、水抜き孔２３の開口面積を大きくしたり、水抜き孔２３の数を多くしたりして、水抜き孔２３の総開口面積（個々の水抜き孔の開口面積を総和した面積）を大きくすればよい。むろん、Qdを小さくするには、水抜き孔２３の総開口面積を小さくすればよい。このようにして、下部排水流出部２２を所望の排水流出流量にすることができる。 The maximum drainage outflow rate Qd (liter / min) of the lower drainage outflow unit 22 is preferably a rate at which the drainage from the washing place W1 temporarily accumulates in the temporary water holding unit 20 to such an extent that the hair in the drainage floats. Here, the maximum drainage outflow rate Qd is the outflow rate of drainage flowing out from the lower drainage outflow unit 22 when the drainage is continuously introduced so that the drainage is accumulated in the temporary water retaining unit 20 up to the upper edge portion 21a. And In addition, if Qd is made smaller than the average water discharge flow rate Qs (liters / minute) of the shower used in the washroom, the wastewater from the washroom is temporarily stored in the temporary water retention unit 20 when the shower is used at the average water discharge flow rate. This is preferable. On the other hand, if Qd is set so that the residence time T of the drainage water temporarily retained in the temporary water retention unit 20 is about several seconds to several tens of seconds (for example, 5 to 15 seconds), the temporary water retention unit 20 promptly uses the washing area. This is preferable because drainage can be removed to remove hair and the like.
In order to increase the drainage outflow rate Qd, the total opening area of the drain holes 23 (individual water areas) can be increased by increasing the opening area of the drain holes 23 or increasing the number of drain holes 23. What is necessary is just to enlarge the area which totaled the opening area of a hole. Of course, in order to reduce Qd, the total opening area of the drain holes 23 may be reduced. In this way, the lower drainage outflow portion 22 can be set to a desired drainage outflow rate.

上部排水流出部３０は、一時保水部２０を取り囲むように設けられ、一時保水部２０の上部（上縁部２１ａ）から外側に向かって斜めに上がるように延出している。この上部排水流出部３０には、排水中の毛髪の流出を抑止しながら一時保水部２０に入りきらない排水を流出させる排水流出孔群３１，３１が複数形成されている。各排水流出孔群３１は、毛髪の流出を抑止しながら排水を流出させる孔３２が複数集合して構成されている。上部排水流出部３０は一時保水部２０に入りきらない排水を流出させるため、上部排水流出部３０の最大の排水流出流量Qu（リットル／分）が下部排水流出部２２の最大排水流出流量Qd（リットル／分）よりも大きくなるようにしている。ここで、最大の排水流出流量Quは、排水が排水桝１１２内で上部排水流出部３０の外縁（外縁部３０ａ）の位置まで溜まっているように連続して排水を導入したときに上部排水流出部３０から流出する排水の流出流量とする。むろん、Quを大きくするには孔３２の総開口面積を大きくすればよく、Quを小さくするには孔３２の総開口面積を小さくすればよい。このようにして、上部排水流出部３０を所望の排水流出流量にすることができる。
本実施形態の上部排水流出部３０は、排水桝１１２の中で容積をできるだけ大きくするため、一時保水部２０の上部よりも緩やかな傾斜で外側へ延出している。 The upper drainage outflow portion 30 is provided so as to surround the temporary water retention portion 20, and extends so as to rise obliquely outward from the upper portion (upper edge portion 21a) of the temporary water retention portion 20. The upper drainage outflow portion 30 is formed with a plurality of drainage outflow hole groups 31 and 31 through which drainage that does not enter the temporary water retaining portion 20 flows out while suppressing the outflow of hair in the drainage. Each drainage outflow hole group 31 includes a plurality of holes 32 through which drainage flows out while suppressing the outflow of hair. Since the upper drainage outflow portion 30 allows the drainage that does not enter the temporary water retaining portion 20 to flow out, the maximum drainage outflow rate Qu (liters / minute) of the upper drainage outflow portion 30 is the maximum drainage outflow rate Qd ( L / min). Here, the maximum drainage outflow rate Qu is the upper drainage outflow when drainage is continuously introduced so that the drainage is accumulated up to the position of the outer edge of the upper drainage outflow part 30 (outer edge part 30a) in the drainage basin 112. Let it be the outflow flow rate of the waste water flowing out from the section 30. Of course, to increase Qu, the total opening area of the hole 32 may be increased, and to decrease Qu, the total opening area of the hole 32 may be decreased. In this way, the upper drainage outflow portion 30 can have a desired drainage outflow rate.
The upper drainage outflow part 30 of the present embodiment extends outward with a gentler slope than the upper part of the temporary water retention part 20 in order to increase the volume of the drainage basin 112 as much as possible.

排水導入部４０は、洗い場Ｗ１からの排水を上部排水流出部３０ではなく、一時保水部２０へ導く。本実施形態の排水導入部４０は、流入部６０と立壁部５０を有し、図５に示すように一時保水部２０内で左回り（一方向）に回転する旋回流が発生するように洗い場Ｗ１からの排水を直接、一時保水部２０内に導入する。なお、一時保水部内で旋回流が一方向に回転するとは、一時保水部内の旋回流が左回りのみであること、一時保水部内の旋回流が右回りのみであること等、一時保水部内の旋回流の回転方向が一つであることを意味するものとする。 The drainage introduction unit 40 guides the drainage from the washing place W1 to the temporary water retention unit 20 instead of the upper drainage outflow unit 30. The drainage introduction part 40 of this embodiment has the inflow part 60 and the standing wall part 50, and is a washing place so that the swirl | flow which rotates counterclockwise (one direction) within the temporary water retention part 20 as shown in FIG. The waste water from W1 is directly introduced into the temporary water retention unit 20. Note that the swirling flow in one direction in the temporary water retention unit means that the swirl flow in the temporary water retention unit is only counterclockwise, the swirl flow in the temporary water retention unit is only clockwise, etc. It shall mean that the direction of rotation of the flow is one.

流入部６０は、排水流出孔群３１，３１同士で挟まれた位置（孔３２同士で挟まれた位置）で上部排水流出部の外縁部３０ａと一時保水部の上縁部２１ａとを繋ぎ、洗い場Ｗ１からの排水を流入口５６から一時保水部２０へ通す。この流入部６０を挟む排水流出孔群３１，３１同士の間隔は、各排水流出孔群３１を構成する孔３２同士の間隔よりも広くされている。ここで、排水流出孔群同士の間隔は一方の排水流出孔群３１と他方の排水流出孔群３１との間の最短距離をいい、孔同士の間隔は排水流出孔群３１内の一つの孔３２と隣接する孔３２との間の最短距離をいうものとする。排水流出孔群３１，３１同士の間隔が広いので、排水は、上部排水流出部３０からほとんど流出せずに流入部６０上を流入口５６から一時保水部２０へ流れる。
本実施形態の流入部６０は、上部排水流出部３０と略同一面内で一時保水部２０を挟む二箇所に設けられ、流入口５６から一時保水部上縁部２１ａに向かって下がっている。 The inflow portion 60 connects the outer edge portion 30a of the upper drainage outflow portion and the upper edge portion 21a of the temporary water retention portion at a position between the drainage outflow hole groups 31, 31 (position between the holes 32), Drainage from the wash area W1 is passed through the inflow port 56 to the temporary water retention unit 20. The interval between the drainage outflow hole groups 31, 31 sandwiching the inflow portion 60 is made wider than the interval between the holes 32 constituting each drainage outflow hole group 31. Here, the interval between the drainage outflow hole groups means the shortest distance between one drainage outflow hole group 31 and the other drainage outflow hole group 31, and the interval between the holes is one hole in the drainage outflow hole group 31. The shortest distance between 32 and the adjacent hole 32 shall be said. Since the interval between the drainage outflow hole groups 31 and 31 is wide, the drainage flows from the inlet 56 to the temporary water retaining unit 20 on the inflow unit 60 without almost flowing out from the upper drainage outflow unit 30.
The inflow part 60 of this embodiment is provided in two places which pinch | interpose the temporary water retention part 20 in the substantially same surface as the upper waste_water | drain outflow part 30, and is falling toward the upper edge part 21a of the temporary water retention part from the inflow port 56.

立壁部５０は、洗い場Ｗ１からの排水を通す流入口５６を設けて排水流出孔群３１（孔３２）が存在する上部排水流出部３０の外側に配置されている。従って、立壁部５０は、排水流出孔群３１に直接排水が流れ込むことを抑止し、排水を流入口５６だけから一時保水部２０へ流入させるガイド機能を有する。
本実施形態の立壁部５０は、各排水流出孔群３１，３１の外側に存在する第一の分割立壁部５２及び第二の分割立壁部５４から構成されている。両分割立壁部５２，５４は、上部排水流出部３０を取り囲むように上部排水流出部の外縁部３０ａから上方へ延出している。立壁部５０があることにより、毛髪等を含む洗い場Ｗ１からの排水が直接上部排水流出部３０に入らないようになっており、毛髪等による上部排水流出部３０の目詰まりを抑止することができる。 The standing wall portion 50 is provided outside the upper drainage outflow portion 30 where the inflow port 56 for passing the drainage from the washing place W1 is provided and the drainage outflow hole group 31 (hole 32) exists. Therefore, the standing wall portion 50 has a guide function that prevents the wastewater from flowing directly into the drainage outflow hole group 31 and allows the wastewater to flow into the temporary water retaining portion 20 only from the inlet 56.
The standing wall portion 50 of the present embodiment is composed of a first divided standing wall portion 52 and a second divided standing wall portion 54 that exist outside the respective drainage outflow hole groups 31, 31. Both the split standing wall portions 52 and 54 extend upward from the outer edge portion 30 a of the upper drainage outflow portion so as to surround the upper drainage outflow portion 30. By having the standing wall portion 50, the drainage from the washing place W1 including hair and the like does not directly enter the upper drainage outflow portion 30, and clogging of the upper drainage outflow portion 30 due to hair or the like can be suppressed. .

各分割立壁部５２，５４の流入口５６側の縁部（区画部５３，５５）は、排水流出孔群３１（上部排水流出部３０）と流入部６０とを区画するように一時保水部２０の方へ曲げられている。これらの区画部５３，５５は、各分割立壁部５２，５４において旋回流の回転方向Ｄ１の下流側に設けられ、流入部６０上の排水が一時保水部２０内における凸部の最上部２４ａ、すなわち、仮想の水平面に投影された下部排水流出部の平面図形の重心ＣＥ１から水平方向へずれた位置に向かうように配置されている。本実施形態の区画部５３，５５の向きは、一時保水部壁部２１の内周面に沿う向きとされている。
なお、重心ＣＥ１から水平方向へずれた位置に向かうとは、図５に示す流入部６０，６０の排水の流れ方向Ｄ１３，Ｄ１３のように、ヘアキャッチャー１０を上から見たときに重心ＣＥ１を通らない方向に向かうことを意味するものとする。 Temporary water retaining portions 20 so that the edge portions (partition portions 53, 55) on the inlet 56 side of the divided standing wall portions 52, 54 partition the drainage outflow hole group 31 (upper drainage outflow portion 30) and the inflow portion 60. It is bent toward These partition parts 53 and 55 are provided on the downstream side in the rotational direction D1 of the swirling flow in each of the divided standing wall parts 52 and 54, and the drainage on the inflow part 60 is the uppermost part 24a of the convex part in the temporary water retaining part 20, That is, it arrange | positions so that it may go to the position which shifted | deviated from the gravity center CE1 of the plane figure of the lower drainage outflow part projected on the virtual horizontal surface to the horizontal direction. The direction of the partition parts 53 and 55 of the present embodiment is the direction along the inner peripheral surface of the temporary water retaining part wall part 21.
Note that heading toward a position shifted in the horizontal direction from the center of gravity CE1 means that the center of gravity CE1 is viewed when the hair catcher 10 is viewed from above, as in the drainage flow directions D13 and D13 of the inflow portions 60 and 60 shown in FIG. It means to go in the direction that does not pass.

以上より、排水導入部４０は、洗い場Ｗ１から排水桝１１２内に流入した排水を立壁部５０の外側から流入口５６，５６へ流入させ、流入部６０，６０に沿って凸部の最上部２４ａから水平方向へずれた位置に向けて一時保水部２０へ導く。これにより、流入部６０，６０上の排水が凸部の最上部２４ａから水平方向へずれた位置に向かうので、一時保水部２０内で排水の旋回流が生じ易い。また、一時保水部２０内に凸部２４があるので、流入部６０，６０上の排水が一時保水部２０内の旋回流を打ち消す方向へ流入し難い。
さらに、ヘアキャッチャー１０が凸部の最上部２４ａを通る鉛直線を中心として２回回転対称であるので、流入部６０，６０上を流れてきた排水が１８０°反対の方向から一時保水部２０内へ流入する。これにより、一時保水部内で排水が旋回流になり易くなり、毛髪等をまとめて捨て易くすることができる。
なお、流入部が一箇所しかないと、排水桝内に流入する排水の流れの向きによって一時保水部内で良好な旋回流が生じないことがある。一方、流入部が三箇所以上あると、流入部から一時保水部へ流入する排水の流れ同士がぶつかることにより一時保水部内で良好な旋回流が生じないことがある。本ヘアキャッチャーは、一時保水部を挟んで流入部が二箇所にあるので、一時保水部内で排水が旋回流になり易い。 As described above, the drainage introduction unit 40 allows the wastewater that has flowed into the drainage basin 112 from the washing place W1 to flow into the inflow ports 56 and 56 from the outside of the standing wall 50, and along the inflow portions 60 and 60, the uppermost portion 24a of the convex portion To the temporary water retention unit 20 toward a position shifted in the horizontal direction. Thereby, since the waste water on the inflow portions 60 and 60 goes to a position shifted in the horizontal direction from the uppermost portion 24a of the convex portion, a swirling flow of the waste water is easily generated in the temporary water retaining portion 20. Moreover, since the convex part 24 exists in the temporary water retention part 20, the waste_water | drain on the inflow parts 60 and 60 does not flow easily in the direction which cancels the swirl | vortex flow in the temporary water retention part 20. FIG.
Furthermore, since the hair catcher 10 is rotationally symmetrical twice around the vertical line passing through the uppermost portion 24a of the convex portion, the drainage that has flowed on the inflow portions 60 and 60 is in the temporary water retaining portion 20 from the opposite direction 180 °. Flow into. Thereby, waste water becomes easy to turn in a temporary water retention part, and it can make it easy to throw away hair etc. collectively.
If there is only one inflow portion, a good swirl flow may not be generated in the temporary water retention portion depending on the direction of the flow of the waste water flowing into the drainage basin. On the other hand, when there are three or more inflow portions, a good swirl flow may not be generated in the temporary water retention portion due to the collision of the drainage flows flowing into the temporary water retention portion from the inflow portion. Since this hair catcher has two inflow portions across the temporary water retention portion, the drainage tends to be swirling in the temporary water retention portion.

ところで、図６に示すように、凸部の最上部２４ａを通る鉛直面で切断した断面における上部排水流出部３０の傾きG1（％）は、同断面における流入部６０の傾きG2（％）とほぼ同じである。一方、同断面における一時保水部壁部２１の上部の傾きG3（％）は、上部排水流出部や流入部の傾きG1，G2よりも大きくされている。
なお、傾きG1％，G2％，G3％は、水平方向の距離Dh₁（mm），Dh₂（mm），Dh₃（mm）に対する鉛直方向の距離をDv₁（mm），Dv₂（mm），Dv₃（mm）として、
G1 ＝（Dv₁／Dh₁）×１００（％）
G2 ＝（Dv₂／Dh₂）×１００（％）
G3 ＝（Dv₃／Dh₃）×１００（％）
で表されるものとする。ここで、傾きを表すDh₁，Dh₂，Dh₃は正の数、Dv₁，Dv₂，Dv₃は０以上の数とする。 By the way, as shown in FIG. 6, the inclination G1 (%) of the upper drainage outflow portion 30 in the cross section cut by the vertical plane passing through the uppermost portion 24a of the convex portion is the inclination G2 (%) of the inflow portion 60 in the same cross section. It is almost the same. On the other hand, the slope G3 (%) of the upper portion of the temporary water retaining wall portion 21 in the same cross section is made larger than the slopes G1 and G2 of the upper drainage outflow portion and the inflow portion.
The slopes G1%, G2%, and G3% are the distances in the vertical direction relative to the horizontal distances Dh ₁ (mm), Dh ₂ (mm), and Dh ₃ (mm), Dv ₁ (mm), Dv ₂ (mm ), Dv ₃ (mm)
_{_{G1 = (Dv 1 / Dh 1}} ) × 100 (%)
_{_{G2 = (Dv 2 / Dh 2}} ) × 100 (%)
G3 = (Dv ₃ / Dh ₃ ) x 100 (%)
It shall be represented by Here, Dh ₁ , Dh ₂ , and Dh ₃ representing inclinations are positive numbers, and Dv ₁ , Dv ₂ , and Dv ₃ are numbers greater than or equal to zero.

石鹸やシャンプー等に由来する泡を水面に有する排水がヘアキャッチャーの孔から流出していくとき、ヘアキャッチャー上面の勾配が急であると、泡が排出されにくい。一方、ヘアキャッチャー上面が水平であると、泡は排出され易くなるものの、毛髪等がヘアキャッチャー上面全体に付着して目詰まりすることがある。
本ヘアキャッチャー１０は、上部排水流出部３０に傾きを設けることにより毛髪等を凹状の一時保水部２０へ集め、上部排水流出部の傾きG1を水平に近くすることにより泡の排出性能を高めている。これにより、本ヘアキャッチャー１０は、凹状の一時保水部２０で毛髪等の異物を集めながら排水の水面にある泡を容易に上部排水流出部３０から排出することができる。 When drainage having foam derived from soap or shampoo on the water surface flows out from the hole of the hair catcher, if the slope of the upper surface of the hair catcher is steep, the foam is difficult to be discharged. On the other hand, when the upper surface of the hair catcher is horizontal, the bubbles are easily discharged, but the hair or the like may adhere to the entire upper surface of the hair catcher and become clogged.
This hair catcher 10 collects hair and the like in the concave temporary water retaining part 20 by providing an inclination in the upper drainage outflow part 30, and improves the foam discharging performance by making the inclination G1 of the upper drainage outflow part close to the horizontal. Yes. Thus, the hair catcher 10 can easily discharge the foam on the surface of the drainage from the upper drainage outflow part 30 while collecting foreign matters such as hair by the concave temporary water retaining part 20.

また、泡を素早く排出するためには各孔３２の開口面積が大きい方がよいため、各孔３２の開口面積は一時保水部の各水抜き孔２３の開口面積よりも大きくしている。 Moreover, since it is better that the opening area of each hole 32 is large in order to discharge bubbles quickly, the opening area of each hole 32 is made larger than the opening area of each drain hole 23 of the temporary water retaining portion.

なお、ヘアキャッチャー１０は、上部排水流出部の外縁部３０ａから下方へ延出した下方延出部４２を有し、締め付けフランジ１４０に対して下方延出部４２が取り付けられるようにされている。図４と図７（ａ）に示すように、下方延出部４２の下部外側面には、９０°間隔で４箇所に溝４３が形成されている。また、下方延出部４２の下縁部４５には、各溝４３に繋がる切欠部４４が９０°間隔で形成されている。各切欠部４４を締め付けフランジの突起１４１ｂに合わせて締め付けフランジ１４０の開口部にヘアキャッチャー１０の下部を挿入し、上下の突起１４１ｂ間に下方延出部の下縁部４５を挿入するようにヘアキャッチャー１０を回転させることにより、ヘアキャッチャー１０が封水筒１５０の上部に取り付けられる。これにより、ヘアキャッチャー１０が排水桝１１２内の所定位置に固定される。
むろん、９０°間隔とされた締め付けフランジ突起１４１ｂ及び溝４３により、締め付けフランジ１４０に取り付けられるヘアキャッチャー１０の向きを９０°単位で変えることができる。また、締め付けフランジの開口部が上面視円形であり、ヘアキャッチャーの下部が下面視円形であるので、締め付けフランジ及びヘアキャッチャーの取付部を変更することにより締め付けフランジに対してヘアキャッチャーを取り付ける向きを３６０°全ての向きに変更可能である。 The hair catcher 10 has a downward extending portion 42 extending downward from the outer edge portion 30 a of the upper drainage outflow portion, and the downward extending portion 42 is attached to the fastening flange 140. As shown in FIG. 4 and FIG. 7A, grooves 43 are formed at four locations at intervals of 90 ° on the lower outer surface of the downward extending portion 42. Moreover, the notch part 44 connected to each groove | channel 43 is formed in the lower edge part 45 of the downward extension part 42 by 90 degree space | interval. Align each notch 44 with the protrusion 141b of the tightening flange, insert the lower part of the hair catcher 10 into the opening of the tightening flange 140, and insert the lower edge 45 of the downwardly extending part between the upper and lower protrusions 141b. By rotating the catcher 10, the hair catcher 10 is attached to the upper part of the sealing tube 150. Thereby, the hair catcher 10 is fixed to the predetermined position in the drainage basin 112.
Of course, the direction of the hair catcher 10 attached to the tightening flange 140 can be changed in units of 90 ° by the tightening flange protrusion 141b and the groove 43 which are spaced by 90 °. In addition, since the opening of the tightening flange is circular when viewed from above and the lower part of the hair catcher is circular when viewed from below, the direction of mounting the hair catcher on the tightening flange can be changed by changing the mounting portion of the tightening flange and hair catcher. It can be changed to all 360 ° orientations.

ところで、ヘアキャッチャー１０は、熱可塑性樹脂といった樹脂材料、ステンレスといった金属材料、これらの組み合わせ、等、種々の材質とすることができ、樹脂材料や金属材料の成形品等を用いることができる。
本ヘアキャッチャー１０を設けた排水トラップ１は、例えば、床材フランジ部１１３の先端部にパッキン１４４を取り付け、トラップ本体のフランジ部１３３に締め付けフランジ１４０を螺入して床材フランジ部１１３とトラップ本体１３０とを互いに固定し、封水筒１５０を締め付けフランジ１４０に取り付け、ヘアキャッチャー１０を締め付けフランジ１４０に取り付け、排水桝の段部１１４にカバー１２０を載置することにより、形成される。 By the way, the hair catcher 10 can be made of various materials such as a resin material such as a thermoplastic resin, a metal material such as stainless steel, and a combination thereof, and a resin material or a molded product of the metal material can be used.
The drainage trap 1 provided with the hair catcher 10 has, for example, a packing 144 attached to the front end of the flooring flange 113, and a tightening flange 140 screwed into the flange 133 of the trap body to trap the flooring flange 113 and the trap. The main body 130 is fixed to each other, the sealing tube 150 is attached to the fastening flange 140, the hair catcher 10 is attached to the fastening flange 140, and the cover 120 is placed on the step 114 of the drain.

（２）ヘアキャッチャーの作用、効果：
次に、本ヘアキャッチャー１０の作用、効果を説明する。
洗い場Ｗ１で生じた排水は、カバー１２０の周囲から排水桝１１２に流入するが、分割立壁部５２，５４により排水流出孔群３１，３１に直接流れ込むことが抑止され、流入口５６，５６からヘアキャッチャー１０内に流入する。流入口５６，５６から流入した排水は、傾きG2を有する流入部６０，６０上を区画部５３，５５に案内されて一時保水部２０内における凸部の最上部２４ａ（重心ＣＥ１）から水平方向へずれた位置に向かって速度を上げる。このため、少ない排水量でも効果的に旋回流を発生させることができる。なお、排水が流入部６０，６０に隣接する孔３２の上を通過することもあるが、このような排水は僅かである。 (2) Action and effect of hair catcher:
Next, the operation and effect of the hair catcher 10 will be described.
Drainage generated at the washing place W1 flows into the drainage basin 112 from the periphery of the cover 120, but is prevented from flowing directly into the drainage outflow hole groups 31 and 31 by the divided standing wall portions 52 and 54, and from the inflow ports 56 and 56. It flows into the catcher 10. The waste water that flows in from the inflow ports 56 and 56 is guided by the partition portions 53 and 55 on the inflow portions 60 and 60 having the inclination G2, and horizontally from the uppermost portion 24a (center of gravity CE1) of the convex portion in the temporary water retention portion 20. Increase the speed toward the offset position. For this reason, a swirl flow can be generated effectively even with a small amount of drainage. In addition, although waste_water | drain may pass on the hole 32 adjacent to the inflow parts 60 and 60, such waste_water | drain is slight.

流入部６０，６０を流れてきた排水は、凸部の最上部２４ａから水平方向へずれた位置に向かって凹状の一時保水部２０に流入する。図５には、流入部６０，６０から一時保水部２０内に流入する排水の流れＤ１３，Ｄ１３を矢印で示している。該排水は、一時保水部２０で一時的に保水されながら左回りに旋回し、下部排水流出部２２から下方へ流出する。排水が一時保水部壁部２１の内周面に沿う方向へ流入するので、旋回流は下部排水流出部２２を通り鉛直に向いた仮想の回転軸ＡＸ１を中心とするような渦流となる。一時保水部２０内で一時的に溜まった排水の渦流の中で、図７（ｂ）に示すように毛髪Ｈ１等の異物が浮遊しながら旋回して集まり、下部排水流出部２２からの毛髪Ｈ１等の流出が抑止される。むろん、下部排水流出部２２から毛髪Ｈ１等が流出しようとしても、複数の水抜き孔２３を形成した下部排水流出部２２に引っ掛かることにより毛髪Ｈ１等の流出が抑止される。
また、一時保水部２０内に凸部２４があることにより一時保水部２０へ導かれる排水が旋回流を打ち消す方向へ流入し難いので、一時保水部２０内で毛髪Ｈ１等がまとまり易い。 The waste water that has flowed through the inflow portions 60, 60 flows into the concave temporary water retaining portion 20 toward a position shifted in the horizontal direction from the uppermost portion 24 a of the convex portion. In FIG. 5, drainage flows D13 and D13 flowing from the inflow portions 60 and 60 into the temporary water retention portion 20 are indicated by arrows. The drainage turns counterclockwise while being temporarily retained by the temporary water retention unit 20, and flows downward from the lower drainage outflow unit 22. Since the drainage flows in the direction along the inner peripheral surface of the temporary water retention wall 21, the swirling flow becomes a vortex that is centered on the virtual rotation axis AX 1 that passes through the lower drainage outlet 22 and is directed vertically. As shown in FIG. 7B, foreign matter such as hair H1 swirls and gathers while floating in the swirl of the wastewater temporarily accumulated in the temporary water retaining portion 20, and the hair H1 from the lower drainage outflow portion 22 Etc. are suppressed. Of course, even if the hair H1 or the like tries to flow out from the lower drainage outflow portion 22, the hair H1 or the like is prevented from flowing out by being caught by the lower drainage outflow portion 22 in which the plurality of drain holes 23 are formed.
Moreover, since the waste water guided to the temporary water retention unit 20 is unlikely to flow in the direction of canceling the swirl flow due to the convex portion 24 in the temporary water retention unit 20, the hair H 1 and the like are easily collected in the temporary water retention unit 20.

また、下部排水流出部２２の排水流出流量を超える排水が一時保水部２０に流入すると、排水は、一時保水部２０に入りきらず上縁部２１ａを超え、上部排水流出部３０から流出する。排水に泡が生じている場合には、緩やかな傾きG1を有する上部排水流出部の排水流出孔群３１から泡が排出される。図７（ｂ）は、排水が上縁部２１ａを超えて位置Ｌ１にまで上昇していることを示している。このとき、下部排水流出部２２から流出した排水が封水面Ｓまで流れ方向Ｄ１４へ落下するとともに、上部排水流出部３０から流出した排水が封水面Ｓまで流れ方向Ｄ１５へ落下する。ここで、一時保水部２０内の排水中の毛髪等は集まって浮遊し旋回しているため、上部排水流出部の孔３２から流出しようとする毛髪等は少ない。また、上部排水流出部３０から毛髪Ｈ１等が流出しようとしても、複数の孔３２が形成された上部排水流出部３０に引っ掛かることにより毛髪Ｈ１等の流出が抑止される。従って、上部排水流出部３０は、従来のヘアキャッチャーに設けられたオーバーフロー用の開口部のように毛髪等が流出してしまう開口部とは異なる。 Further, when waste water exceeding the drainage outflow rate of the lower drainage outflow portion 22 flows into the temporary water retention portion 20, the wastewater does not enter the temporary water retention portion 20, exceeds the upper edge portion 21 a, and flows out from the upper drainage outflow portion 30. When bubbles are generated in the drainage, the bubbles are discharged from the drainage outflow hole group 31 of the upper drainage outflow portion having a gentle inclination G1. FIG.7 (b) has shown that the waste_water | drain is rising to the position L1 exceeding the upper edge part 21a. At this time, the wastewater that has flowed out from the lower drainage outflow portion 22 falls in the flow direction D14 to the sealing surface S, and the drainage that has flowed out from the upper drainage outflow portion 30 falls in the flow direction D15 to the sealing surface S. Here, since the hair and the like in the drainage water in the temporary water retention unit 20 gather and float and swirl, there are few hairs and the like trying to flow out from the hole 32 of the upper drainage outflow part. Moreover, even if the hair H1 or the like is about to flow out from the upper drainage outflow portion 30, the outflow of the hair H1 or the like is suppressed by being caught by the upper drainage outflow portion 30 in which the plurality of holes 32 are formed. Therefore, the upper drainage outflow portion 30 is different from an opening through which hair or the like flows out, such as an overflow opening provided in a conventional hair catcher.

一時保水部２０に排水が流入しなくなると、毛髪Ｈ１等が浮遊して集まった排水が下部排水流出部２２から流出し、図７（ｃ）に示すように毛髪Ｈ１等がまとまった状態で一時保水部２０内に残存する。ここで、一時保水部２０の底部に凸部２４が設けられているので、集まった毛髪Ｈ１等が凸部２４に支えられ、該毛髪等と一時保水部底部との接触面積が少ない。捕集した毛髪等を捨てる際には、排水桝１１２からカバー１２０を取り外した後にヘアキャッチャー１０を締め付けフランジ１４０から取り外して裏返す作業をすればよい。毛髪等がまとまった状態で一時保水部２０内に存在するので、上下逆にされた一時保水部２０から毛髪等が容易に落下する。また、凸部２４に支えられた毛髪Ｈ１等と一時保水部２０底部との接触面積が少ないので、毛髪等を捨てる際に一時保水部２０の内側面から毛髪等が離れやすい。従って、ヘアキャッチャーから容易に毛髪等を除去することができる。
図８（ｄ）に示した従来例のように排水が速やかにヘアキャッチャーを通過するようにされていると毛髪等がヘアキャッチャーに絡み付いて毛髪等を除去し難くなるが、本ヘアキャッチャー１０は、一時保水部の孔が少なく、排水が徐々に下部排水流出部２２を通過するので、毛髪等が一時保水部に絡み付かず、良好な毛髪除去性を得ることができ、清掃し易い。 When the drainage does not flow into the temporary water retaining unit 20, the drainage collected by the floating hair H1 and the like flows out from the lower drainage outflow unit 22 and temporarily stays in the state where the hair H1 and the like are gathered as shown in FIG. It remains in the water retention unit 20. Here, since the convex part 24 is provided in the bottom part of the temporary water retention part 20, the gathered hair H1 etc. are supported by the convex part 24, and the contact area of this hair etc. and a temporary water retention part bottom is small. When discarding collected hair or the like, the hair catcher 10 may be removed from the tightening flange 140 and turned over after removing the cover 120 from the drainage basin 112. Since the hair or the like is present in the temporary water retention unit 20 in a state of being gathered, the hair or the like easily drops from the temporary water retention unit 20 turned upside down. Moreover, since the contact area of the hair H1 etc. supported by the convex part 24 and the bottom part of the temporary water retention part 20 is small, when discarding hair etc., hair etc. are easy to leave | separate from the inner surface of the temporary water retention part 20. Therefore, hair etc. can be easily removed from the hair catcher.
If the drainage quickly passes through the hair catcher as in the conventional example shown in FIG. 8 (d), it becomes difficult for the hair etc. to get entangled with the hair catcher, but this hair catcher 10 Since there are few holes in the temporary water retention part and the wastewater gradually passes through the lower drainage outflow part 22, hair or the like is not entangled with the temporary water retention part, and good hair removability can be obtained and cleaning is easy.

また、図８（ａ）〜（ｄ）に示した従来例のように洗い場からの全排水が一度にヘアキャッチャー全体を通過すると毛髪等がヘアキャッチャー全体に付着して目詰まりし易くなるが、本ヘアキャッチャー１０は、排水流出孔群３１に直接排水が流れ込まないので、上部排水流出部３０の閉塞を抑止して安定した排水能力を得ることができる。
さらに、図８（ａ）〜（ｄ）に示した従来例では封水筒や排水桝等を特別な構造にすることより渦流を発生させる必要があるが、本ヘアキャッチャー１０は、上述した良好な毛髪除去性及び安定した排水能力をヘアキャッチャー単独の構造のみで得ることができる。特に、図８（ａ）〜（ｃ）に示した従来例では洗い場からの排水が全て排水量調節部品９０４を通過することにより排水能力が制限されるが、本ヘアキャッチャー１０によると、封水筒の排水能力を制限する必要が無いので、安定した排水能力が得られる。また、図８（ｄ）に示した従来例では渦流を発生させるために浴槽排水が必要であるが、本ヘアキャッチャー１０は、浴槽排水を用いず洗い場シャワー等の洗い場からの排水だけで良好な毛髪除去性を得ることができる。 Moreover, when all the waste water from the washing place passes through the entire hair catcher at a time as in the conventional example shown in FIGS. 8A to 8D, the hair etc. adheres to the entire hair catcher and is easily clogged. Since the hair catcher 10 does not directly flow into the drainage outflow hole group 31, the hair catcher 10 can prevent the upper drainage outflow portion 30 from being blocked and obtain a stable drainage capacity.
Furthermore, in the conventional example shown in FIGS. 8A to 8D, it is necessary to generate a vortex by making a sealed tube, a drainage tub, etc. a special structure. Hair removability and stable drainage ability can be obtained only by the structure of the hair catcher alone. In particular, in the conventional example shown in FIGS. 8A to 8C, the drainage capacity is limited by all drainage from the washing place passing through the drainage amount adjusting component 904, but according to the hair catcher 10, Since there is no need to limit the drainage capacity, a stable drainage capacity can be obtained. In addition, in the conventional example shown in FIG. 8D, bathtub drainage is required to generate eddy currents, but this hair catcher 10 is good only by draining from a washing place such as a washing place shower without using bathtub drainage. Hair removability can be obtained.

従って、本ヘアキャッチャー１０によると、ヘアキャッチャーを設ける排水トラップに特別な構造を設ける必要が無く、良好な毛髪除去性及び良好な清掃性並びに安定した排水能力を得ることが可能となる。むろん、これらの性能は、既存の排水トラップからヘアキャッチャーのみを交換することにより得られることになる。従って、排水トラップを安価にすることが可能になる。
また、本ヘアキャッチャー１０は、締め付けフランジ１４０の内径とほぼ同じ外径のコンパクトな大きさで上述した良好な毛髪除去性及び清掃性並びに安定した排水能力を得ることができる。 Therefore, according to the present hair catcher 10, it is not necessary to provide a special structure in the drain trap provided with the hair catcher, and it is possible to obtain good hair removal property, good cleaning property and stable drainage capability. Of course, these performances can be obtained by replacing only the hair catcher from the existing drain trap. Accordingly, the drain trap can be made inexpensive.
In addition, the present hair catcher 10 can obtain the above-described good hair removal property and cleanability as well as stable drainage capability with a compact size having an outer diameter that is substantially the same as the inner diameter of the fastening flange 140.

なお、洗い場から流入する排水が少ないときには一時保水部２０内で旋回流が生じないこともあるが、この場合でも一時保水部２０内で一時的に溜まった排水の中で毛髪等が浮遊して集まり、下部排水流出部２２からの毛髪等の流出が抑止される。むろん、流入する排水が一時保水部２０に一時的に保水されない程度に少ないときであっても、複数の水抜き孔２３を形成した下部排水流出部２２により毛髪等の流出が抑止され、下部排水流出部２２から排水が徐々に流出するので毛髪等の絡み付きによる毛髪除去性の低下が抑止される。 In addition, when there is little waste water flowing in from the washing place, a swirl flow may not be generated in the temporary water retention unit 20, but even in this case, hair etc. floats in the waste water temporarily accumulated in the temporary water retention unit 20. Collecting, the outflow of hair and the like from the lower drainage outflow portion 22 is suppressed. Of course, even when the inflowing wastewater is so small that it is not temporarily retained in the temporary water retaining portion 20, the lower drainage outflow portion 22 having a plurality of drain holes 23 prevents outflow of hair and the like. Since the waste water gradually flows out from the outflow portion 22, a reduction in hair removability due to the entanglement of hair or the like is suppressed.

（３）変形例：
本発明のヘアキャッチャーは、種々の変形例が考えられる。
ヘアキャッチャーを構成する各部は、全て一体化されていてもよいし、独立した部材で構成されてもよい。
洗い場からの排水を一時保水部へ通す流入口は、立壁部に設けられる隙間以外にも、これらの部位に設けられる開口等でもよい。
上記下部排水流出部や上記上部排水流出部は、複数の孔で形成する以外にも、繊維や針金等を編んで形成した網で構成したり、複数のスリットで形成したりすることが可能である。
上記上部排水流出部の外側に配置される立壁部は、鉛直方向に延出した形状以外にも、鉛直方向からずれた方向に延出した形状等でもよい。 (3) Modification:
Various modifications can be considered for the hair catcher of the present invention.
All the parts constituting the hair catcher may be integrated, or may be constituted by independent members.
In addition to the gap provided in the standing wall, the inflow port through which the wastewater from the washing place is passed to the temporary water holding unit may be an opening provided in these parts.
The lower drainage outflow part and the upper drainage outflow part can be formed by a net formed by knitting fibers or wires, etc., or can be formed by a plurality of slits, in addition to being formed by a plurality of holes. is there.
In addition to the shape extending in the vertical direction, the standing wall portion disposed outside the upper drainage outflow portion may have a shape extending in a direction shifted from the vertical direction.

一時保水部の底部に設けられる凸部の上方へ凸とされた形状には、上方へ膨出した形状のみならず、上方へ突出した形状、上方へ延出した形状、等も含まれる。
一時保水部の底部に設けられる凸部の最上部は、下部排水流出部の平面図形の重心からずれていてもよい。
一時保水部の底部には、上述した凸部が複数設けられてもよい。
一時保水部の水抜き孔は、凸部全体にわたって設けられるのみならず、一時保水部の最下部のみ等、凸部の周囲にのみ設けられてもよい。
上部排水流出部に設けられる排水流出孔群は、複数のみならず、単数でもよい。上部排水流出部に一つのみ排水流出孔群が設けられる場合、該排水流出孔群が一時保水部の周りの一周近くにわたって配置され、該排水流出孔群の右回り方向の縁部と該排水流出孔群の左回り方向の縁部とで挟まれた位置に流入部が設けられてもよい。この場合の流入部も、上部排水流出部の排水流出孔群同士で挟まれた位置で上部排水流出部の外縁と一時保水部の上部とを繋ぐ部位となる。
上部排水流出部には、上記排水流出孔群の代わりに、単一の孔で構成される排水流出孔が設けられてもよい。従って、上部排水流出部に設けられる孔は、複数のみならず、単数でもよい。 The shape of the convex portion provided on the bottom of the temporary water retaining portion is convex upward, and includes not only the shape bulging upward, but also the shape protruding upward, the shape extending upward, and the like.
The uppermost part of the convex part provided at the bottom part of the temporary water retention part may be displaced from the center of gravity of the plan view of the lower drainage outflow part.
A plurality of the convex portions described above may be provided on the bottom of the temporary water retention portion.
The drain hole of the temporary water retention part is not only provided over the entire convex part, but may be provided only around the convex part, such as only the lowermost part of the temporary water retention part.
The number of drainage outflow holes provided in the upper drainage outflow part is not limited to a plurality, but may be one. When only one drainage outflow hole group is provided in the upper drainage outflow part, the drainage outflow hole group is arranged over the circumference around the temporary water retaining part, and the clockwise edge of the drainage outflow hole group and the drainage The inflow portion may be provided at a position sandwiched between the counterclockwise edges of the outflow hole group. The inflow portion in this case is also a portion that connects the outer edge of the upper drainage outflow portion and the upper portion of the temporary water retention portion at a position sandwiched between the drainage outflow hole groups of the upper drainage outflow portion.
The upper drainage outflow part may be provided with a drainage outflow hole constituted by a single hole instead of the drainage outflow hole group. Therefore, the number of holes provided in the upper drainage outflow portion is not limited to a plurality, but may be a single number.

上記排水導入部が一時保水部内に発生させる旋回流は、上述した実施形態とは逆の右回りでもよい。また、旋回流の回転軸ＡＸ１の向きは、鉛直方向から斜めにずれた方向でもよく、水平方向でもよい。
上記排水導入部が一時保水部内へ排水を導く方向は、一時保水部壁部の内周面に沿う方向以外とすることができる。例えば、排水を導く方向を下部排水流出部に向かう方向とすると、一時保水部内で水平に向いた回転軸を中心とするような旋回流が発生すると考えられる。この場合も、一時保水部内で毛髪等が浮遊しながら旋回して集まり、毛髪等がまとまった状態で一時保水部内に残存して、良好な毛髪除去性を得ることができると考えられる。
上記一時保水部が上下逆の角錐の形状、又は、上下逆の角錐の頂点及び稜線を丸くしたような形状である場合、上記排水導入部は一時保水部壁部の水平断面の辺に沿った方向へ洗い場からの排水を導いてもよい。 The swirl flow generated in the temporary water retention unit by the drainage introduction unit may be clockwise as opposed to the above-described embodiment. Further, the direction of the rotational axis AX1 of the swirling flow may be a direction obliquely shifted from the vertical direction or a horizontal direction.
The direction in which the drainage introduction part guides drainage into the temporary water retention part can be other than the direction along the inner peripheral surface of the temporary water retention part wall part. For example, if the direction of leading the drainage is a direction toward the lower drainage outflow part, it is considered that a swirling flow is generated with the rotation axis oriented horizontally in the temporary water retention part. Also in this case, it is considered that hair or the like floats and gathers while floating in the temporary water retaining portion, and remains in the temporary water retaining portion in a state where the hair or the like is gathered, so that good hair removability can be obtained.
In the case where the temporary water retention part is in the shape of a pyramid that is upside down or rounded at the apex and ridge line of the upside down pyramid, the drainage introduction part is along the side of the horizontal section of the wall part of the temporary water retention part You may guide the drainage from the washroom in the direction.

上記排水導入部が旋回流を発生させないように洗い場からの排水を一時保水部へ導く場合でも、一時保水部内で一時的に溜まった排水の中で毛髪等が浮遊して集まり、下部排水流出部から排水が抜け落ちたときに毛髪等が集まった状態で一時保水部内に残存する。従って、良好な毛髪除去性及び安定した排水能力を得る効果が得られる。 Even when the waste water introduction part guides the waste water from the washing place to the temporary water holding part so that the swirling flow is not generated, the hair etc. floats and gathers in the waste water temporarily accumulated in the temporary water holding part, and the lower drainage outflow part When the drainage drains from the water, it remains in the temporary water retaining portion in a state where the hair is collected. Therefore, the effect of obtaining good hair removability and stable drainage ability is obtained.

排水トラップを構成する締め付けフランジ等の部材にヘアキャッチャーを取り付ける操作を行うための把手等の部位を有するヘアキャッチャーも、本発明の作用、効果を奏する。 A hair catcher having a part such as a handle for performing an operation of attaching the hair catcher to a member such as a tightening flange constituting the drain trap also has the effects and advantages of the present invention.

また、流入した排水を保水する凹状の保水部は、上述した下部排水流出部を有する一時保水部のみならず、下部排水流出部２２の無い保水部でもよい。下部排水流出部が無い場合、保水部２０に流入した排水は、全て上部排水流出部３０から流出することになる。ここで、毛髪の比重が１．２〜１．３程度と水の比重よりも大きいため、保水部２０の中で毛髪には沈む力が加わる。これにより、保水部２０に入りきらない排水が上部排水流出部３０から流出する際に流出しようとする毛髪は少ない。また、毛髪が上部排水流出部３０へ移動しても、排水は単に上部排水流出部３０からオーバーフローする訳ではなく、上部排水流出部３０で毛髪の流出が抑止される。
一方、毛髪が細長いため、保水部２０内に溜まった排水の中で毛髪に加わる沈む力よりも排水の流れの影響の方が大きく、保水部２０内で毛髪が浮遊する。これにより、保水部２０内で毛髪等が集まり、毛髪等が集まった状態で保水部２０内に残存する。従って、捕集した毛髪等を容易に除去することができる。
また、洗い場からの排水が保水部２０へ導かれるので、上部排水流出部３０の閉塞が抑止され、安定した排水能力を得ることができる。 Further, the concave water retaining part that retains the drained water that flows in may be not only the temporary water retaining part having the lower drainage outflow part described above, but also the water retaining part without the lower drainage outflow part 22. When there is no lower drainage outflow portion, all of the wastewater that flows into the water retaining portion 20 flows out from the upper drainage outflow portion 30. Here, since the specific gravity of the hair is about 1.2 to 1.3, which is larger than the specific gravity of water, a force that sinks into the hair is added in the water retaining portion 20. Thereby, there is little hair which tries to flow out when the waste water that does not enter the water retaining portion 20 flows out from the upper drainage outflow portion 30. Even if the hair moves to the upper drainage outflow portion 30, the drainage does not simply overflow from the upper drainage outflow portion 30, and the hair drainage is suppressed at the upper drainage outflow portion 30.
On the other hand, since the hair is elongated, the influence of the drainage flow is greater than the sinking force applied to the hair in the drainage accumulated in the water retention unit 20, and the hair floats in the water retention unit 20. Thereby, hair etc. gather in the water retention part 20, and remain in the water retention part 20 in the state where hair etc. gathered. Therefore, the collected hair and the like can be easily removed.
Moreover, since the waste water from the washing place is guided to the water retention unit 20, the upper drainage outflow portion 30 is prevented from being blocked, and a stable drainage capacity can be obtained.

なお、本発明を適用可能な洗い場は、浴室の洗い場以外にも、洗面化粧台の排水トラップに繋がる洗面台、理容店や美容室の排水トラップに繋がる洗面台、等でもよい。
