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。
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. 8 (b) shows the water direction guide portion 913. It is a side view which shows the hair catcher 911 integrated.
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.

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(c)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 (c) 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(d)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。

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)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、洗い場からの全排水がヘアキャッチャー901,911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 FIG.
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, since all the waste water from the washing area flows into the entire hair catchers 901 and 911, hair or the like adheres to the entire hair catcher, and it is difficult to remove the hair from the hair catcher or the hair catcher may be clogged. is there.

図8(c)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つきやすい。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. 8C requires bathtub drainage in order to generate a vortex, and it is necessary to form a water discharge port 921 for discharging bathtub drainage in the drainage 923. In addition, since the hair catcher 925 is disposed 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(d)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つきやすい。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. 8D is provided not in the bathroom but in the kitchen, a net basket 933 is used instead of a hair catcher. In addition, since the drainage is not retained in the mesh basket 933 and quickly passes through the entire mesh basket 933, 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 an object of the present invention is to provide a hair catcher capable of easily removing collected hair and the like. And

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、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る凹状の一時保水部と、該一時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一時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、排水を前記一時保水部へ通す流入口を設けて前記上部排水流出部の外側に配置された立壁部と、該立壁部から外側へ延出して洗い場からの排水を受けるとともに、前記流入口に向けて下がる勾配を有するフランジ部とを備えることを特徴とする。   In order to achieve the above object, the present invention is a hair catcher provided in a drainage trap, having a lower drainage outflow part in the lower part for allowing drainage to flow out while suppressing the outflow of hair in the drainage. A concave temporary water retaining part that allows the drainage to flow out from the lower drainage outflow part while temporarily retaining water, and extends from the upper part of the temporary water retaining part, and enters the temporary water retaining part while suppressing the outflow of hair during drainage. An upper drainage outlet for draining undrained drainage, an upright wall provided outside the upper drainage outlet by providing an inflow port for passing drainage to the temporary water retention part, and a washing place extending outward from the standing wall And a flange portion having a slope that decreases toward the inflow port.

すなわち、洗い場からの排水は、流入口に向けて下がる勾配を有するフランジ部により流速を高めながら流入口へ案内され、該流入口から凹状の一時保水部へ導入され、該一時保水部で一時的に保水されながら下部排水流出部から流出する。このとき、排水中の毛髪の流出が抑止される。また、一時保水部に入りきらない排水は、一時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、一時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。
一時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る。ここで、フランジ部により流速を高めた排水が流入口から一時保水部へ導入されるので、一時保水部内の排水の流れが一定となり、排水中で浮遊する毛髪等が効果的に集まり、一時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一時保水部内に残存する。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、上述した良好な毛髪除去性は、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 inlet while increasing the flow velocity by the flange portion having a gradient descending toward the inlet, and is introduced from the inlet to the concave temporary water retaining portion. It flows out from the lower drainage outflow part while keeping the water. At this time, the outflow of the hair in the waste water is suppressed. Moreover, the waste water which cannot enter the temporary water retention part flows out from the upper drainage outflow part extended from the upper part of the temporary water retention part. Here, the waste water that does not completely enter the temporary water retention 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 water temporarily stored in the temporary water retention section, hairs etc. float and gather. Here, since the waste water whose flow velocity is increased by the flange portion is introduced from the inlet to the temporary water retention portion, the flow of the waste water in the temporary water retention portion becomes constant, and the hair etc. floating in the waste water gathers effectively, and the temporary water retention When the drainage drains from the part, the hair etc. remain in the temporary water retaining part in a state where it gathers. Therefore, it is possible to obtain performance that can easily remove the collected hair, that is, good hair removability.
Further, the above-described good hair removability 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。従って、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や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。
上記一時保水部が排水を一時的に保水することは、一時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、一時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一時保水部内に存在する排水の状態は、一時保水部内に一時的に保水されている状態に含まれる。
上記凹状の一時保水部は排水を受けて一時的に保水する形状であればよく、該一時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、等の形状が含まれる。また、これらの形状の底部に上方へ突出したり膨出したりした部位が設けられた形状の一時保水部も、上記凹状の一時保水部に含まれる。
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. Therefore, a lower drainage outflow part and an upper drainage outflow part mean a part from which water containing hair flows out.
The lower drainage outflow portion and the upper drainage outflow portion that suppress the outflow of hair during drainage do not have to stop all the hair. That is, deterrence is not limited to stopping everything.
The temporary retention of the drainage by the temporary water retention unit means that the drainage is temporarily accumulated while drainage flows out in the temporary retention unit. Therefore, the residence time of the wastewater in the temporary water retention unit is a finite time. The state of the drainage that exists in the temporary water retention unit while the hair is floating therein is included in the state in which the water is temporarily retained in the temporary water retention unit.
The concave temporary water retaining portion may have any shape that receives drainage and temporarily retains water, and the shape of the temporary water retaining portion includes a bowl shape, a hemispherical shape, an upside down conical shape, an upside down pyramid shape, and the like. Shape is included. Moreover, the concave temporary water retention part is also included in the shape of the temporary water retention part in which the bottom part of these shapes protrudes or bulges upward.

ところで、前記一時保水部内で一方向に回転する旋回流が発生するように前記流入口からの排水を前記一時保水部へ導くと、排水の旋回流により一時保水部内で毛髪等がまとまるので、毛髪除去性が向上する。
上記旋回流は、一時保水部内に存在する排水が回転する流れをいい、一時保水部に流入した排水が下部排水流出部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。
By the way, when the waste water from the inlet is guided to the temporary water holding portion so that a swirling flow rotating in one direction is generated in the temporary water retaining portion, the hair etc. is gathered in the temporary water retaining portion by the swirling flow of the waste water. Removability is improved.
The swirling flow refers to a flow in which the drainage existing in the temporary water retention unit rotates, and there is no limitation on the number of rotations until the drainage that has flowed into the temporary water retention unit flows out from the lower drainage outflow unit. 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.

本発明によれば、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。   ADVANTAGE OF THE INVENTION According to this invention, it is not necessary to provide a special structure in the drain trap which provides a hair catcher, and the hair catcher which can acquire favorable hair removability can be provided.

As a result, the sealing tube 150 is fixed at a predetermined position in the trap body 130. Here, a gap is provided between the lower end of the sealing cylinder 150 and the bottom surface of the trap body 130.

ヘアキャッチャー10は、図1〜図6に示す一時保水部20と上部排水流出部30と立壁部50とフランジ部70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、立壁部50及びフランジ部70とともに傾斜部60が洗い場W1からの排水を一時保水部20へ導く排水導入部40とされている。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。   The hair catcher 10 includes a temporary water retaining portion 20, an upper drainage outflow portion 30, a standing wall portion 50, and a flange portion 70 shown in FIGS. 1 to 6, and collects dust such as hair from the drainage. In the hair catcher 10, the inclined portion 60 together with the standing wall portion 50 and the flange portion 70 is a drainage introduction portion 40 that guides drainage from the washing place W <b> 1 to the temporary water retention portion 20. 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.

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ている。本実施形態の一時保水部20は、四隅に段部114を有する排水桝112の中で容積をできるだけ大きくするため、上下逆の四角錐の頂点及び稜線を丸くしたような形状としてある。この四角錐の頂点近傍となる一時保水部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。
The temporary water retaining portion 20 is formed in a concave shape that is open at the top and recessed downward. The temporary water retaining portion 20 of the present embodiment has a shape in which the apex and ridgeline of the inverted quadrangular pyramid are rounded in order to increase the volume as much as possible in the drainage basin 112 having stepped portions 114 at the four corners. A plurality of drain holes 23 are formed in the lower portion of the temporary water retaining portion 20 near the apex of the quadrangular pyramid to allow the drainage to flow out substantially downward while preventing 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 toward the outside. 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.

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排水を流出させる孔32が複数形成されている。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、排水が上部排水流出部30の外縁部30aの最も低い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 extends from the upper portion (upper edge portion 21a) of the temporary water retention portion 20 so as to rise obliquely outward. The upper drainage outlet 30 is formed with a plurality of holes 32 through which drainage flows out while suppressing the outflow of hair during drainage. 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 drainage that flows out from the upper drainage outflow part 30 when the drainage is continuously introduced so that the drainage is accumulated to the lowest position of the outer edge part 30a of the upper drainage outflow part 30. The outflow rate of 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、立壁部50と傾斜部60とフランジ部70により、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。
立壁部50は、排水を一時保水部へ通す流入口56を設けて上部排水流出部30の外側に配置されている。本実施形態の立壁部50は、流入口56を洗い場W1側に設け浴槽側を離間させた第一の分割立壁部52及び第二の分割立壁部54から構成されている。洗い場W1からの排水の多くは洗い場W1側から排水桝112に流入するので、ヘアキャッチャー10上の流入口56は洗い場W1からの排水の多くが流れ込む位置に設けられていることになる。両分割立壁部52,54は、上部排水流出部30を囲むように上部排水流出部30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側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 drainage introduction unit 40 directly and temporarily removes the drainage from the washing place W1 by the standing wall unit 50, the inclined unit 60, and the flange unit 70 so that a swirling flow that rotates counterclockwise (one direction) is generated in the temporary water retention unit 20. Introduce into the 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.
The standing wall portion 50 is disposed outside the upper drainage outflow portion 30 with an inflow port 56 through which drainage is passed to the temporary water retention portion. The standing wall portion 50 of the present embodiment includes a first divided standing wall portion 52 and a second divided standing wall portion 54 in which the inflow port 56 is provided on the washing place W1 side and the bathtub side is separated. Since much of the waste water from the washing place W1 flows into the drainage basin 112 from the washing place W1 side, the inlet 56 on the hair catcher 10 is provided at a position where much of the waste water from the washing place W1 flows. Both the split standing wall portions 52 and 54 extend upward from the outer edge portion 30 a of the upper drainage outflow portion 30 so as to surround the upper drainage outflow portion 30. By having the standing wall portion 50, the waste water from the washing station W1 side 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. it can.

傾斜部60は、流入口56を通って立壁部50の外側から一時保水部壁部21の内周面に沿う方向に向かって、すなわち、一時保水部20内において仮想の水平面HP1に投影された下部排水流出部22の平面図形の重心CE1から水平方向へずれた位置に向かって下がっている。
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4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。
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とは、図4に示す傾斜部60の排水の流れ方向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。
また、排水の流れ方向D13の向きは傾斜部60において最も傾斜した向きであり、この向きが傾斜部60の下がる向きであるものとする。本実施形態の傾斜部60が下がる向きは、排水が流れていく方向に見たときに下部排水流出部22から右側とされている。
The inclined part 60 is projected from the outside of the standing wall part 50 through the inflow port 56 toward the direction along the inner peripheral surface of the temporary water retaining part wall part 21, that is, in the temporary water retaining part 20, onto the virtual horizontal plane HP1. The lower drainage outflow portion 22 is lowered toward the position shifted in the horizontal direction from the center of gravity CE1 of the plan view.
Here, the plan view of the hair catcher 10 projected onto the virtual horizontal plane HP1 corresponds to the plan view of FIG. 4, 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.
When heading to the position shifted in the horizontal direction from the center of gravity CE1 of the plan view of the lower drainage outflow portion projected on the virtual horizontal plane, the hair catcher 10 is moved like the drainage flow direction D13 of the inclined portion 60 shown in FIG. When viewed from above, it means to go in a direction not passing through the center of gravity CE1.
Further, the direction of the drainage flow direction D13 is the direction most inclined in the inclined portion 60, and this direction is the direction in which the inclined portion 60 is lowered. The direction in which the inclined portion 60 of the present embodiment is lowered is the right side from the lower drainage outflow portion 22 when viewed in the direction in which the drainage flows.

フランジ部70は、上部排水流出部の外縁部30aから外方、すなわち、立壁部50から外側へ延出し、立壁部50の外側で洗い場W1からの排水を受ける。また、フランジ部70は、流入口56に向けて下がる勾配を有し、排水を傾斜部60へ案内する。本実施形態のフランジ部70は、主に第一の分割立壁部52の外側となる第一の領域72と、主に第二の分割立壁部54の外側となる第二の領域74と、これらの領域72,74の境界部分で一段上がって洗い場側段部114a,114aに載置される隅部76,77とに区分することができる。第一の領域72と第二の領域74は、浴槽側を離間させ、ともに流入口56へ繋がっている。   The flange portion 70 extends outward from the outer edge portion 30 a of the upper drainage outflow portion, that is, outward from the standing wall portion 50, and receives drainage from the washing place W <b> 1 outside the standing wall portion 50. Further, the flange portion 70 has a slope that decreases toward the inflow port 56, and guides drainage to the inclined portion 60. The flange portion 70 of the present embodiment includes a first region 72 that is mainly outside the first divided standing wall portion 52, a second region 74 that is mainly outside the second divided standing wall portion 54, and these Can be divided into corners 76 and 77 placed one step up at the boundary between the regions 72 and 74 and placed on the washing-stage steps 114a and 114a. The first region 72 and the second region 74 are separated from the bathtub side, and are both connected to the inflow port 56.

第一の領域72は、右回りに少しずつ下がり、一時保水部20内の旋回流の回転方向D1とほぼ同じ回転方向へ排水を案内する。図5(a)は、第一の分割立壁部52に沿った部分の第一の領域72を断面視している。同図(a)に示すように、この部分の第一の領域72は、流入口56に向けて下がる勾配(下り勾配G1%)を有している。
第二の領域74は、洗い場側に向かって少しずつ下がり、浴槽側から流入口56へ排水を案内する。図5(b)は、第二の分割立壁部54に沿った部分の第二の領域74を断面視している。同図(b)に示すように、この部分の第二の領域74も、流入口56に向けて下がる勾配(下り勾配G2%)を有している。
The first region 72 is gradually lowered clockwise, and guides the drainage in the rotational direction substantially the same as the rotational direction D1 of the swirling flow in the temporary water retention unit 20. FIG. 5A is a cross-sectional view of a portion of the first region 72 along the first divided upright wall portion 52. As shown in FIG. 5A, the first region 72 of this portion has a gradient (downward gradient G1%) that decreases toward the inflow port 56.
The second region 74 is gradually lowered toward the washing area, and guides the drainage from the bathtub side to the inflow port 56. FIG. 5B is a cross-sectional view of the second region 74 in a portion along the second divided standing wall portion 54. As shown in FIG. 5B, the second region 74 in this portion also has a gradient that descends toward the inflow port 56 (downgradient G2%).

なお、下り勾配G1%,G2%は、水平方向の距離Dh1(mm),Dh2(mm)に対する鉛直方向に下がる距離Dv1(mm),Dv2(mm)の百分率(%)で表されるものとする。ここで、下り勾配を表すDh1,Dh2,Dv1,Dv2は、正の数である。本実施形態のフランジ部70は、G1>G2とされている。第二の領域74上の排水は、一時保水部20内の旋回流の回転方向D1と逆方向から案内されるが、第二の領域の下り勾配G2が第一の領域の下り勾配G1よりも小さいので第一の領域72へ流れ難い。 The descending slopes G1% and G2% are expressed as percentages (%) of the distances Dv 1 (mm) and Dv 2 (mm) that descend in the vertical direction relative to the horizontal distances Dh 1 (mm) and Dh 2 (mm). Shall be. Here, Dh 1 , Dh 2 , Dv 1 , and Dv 2 representing the downward gradient are positive numbers. The flange portion 70 of the present embodiment satisfies G1> G2. The drainage on the second region 74 is guided from the direction opposite to the rotational direction D1 of the swirling flow in the temporary water retention unit 20, but the downward gradient G2 of the second region is lower than the downward gradient G1 of the first region. Since it is small, it is difficult to flow to the first region 72.

隅部76,77は、第一の領域72上を流れる排水を右回りに誘導したり、第二の領域74上を流れてきた排水を流入口56へ誘導したりする機能も有する。   The corner portions 76 and 77 also have a function of guiding the drainage flowing on the first region 72 clockwise or guiding the drainage flowing on the second region 74 to the inlet 56.

なお、カバー120を取り外す際に手かけ部122に手を掛け易くするため、ヘアキャッチャー10は、浴槽側に立壁部50が設けられていない領域があり、上部排水流出部30の浴槽側縁部30bがヘアキャッチャー自体の浴槽側縁部に繋がった形状とされている。ここで、洗い場W1からの排水の多くは洗い場W1側から排水桝112に流入するので、フランジ部70上から傾斜部60を経由して一時保水部20に流入する排水に比べてヘアキャッチャー10の浴槽側縁部から上部排水流出部30へ直接流入する排水は少ない。
以上説明した立壁部50及びフランジ部70により、洗い場W1からの排水が主に流入口56へ案内される。フランジ部70は、流入口56に向けて下がる勾配を有しているので、案内する排水の流速を高め、該排水を傾斜部60へ導く。傾斜部60は、該排水を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(以下、下部排水流出部の重心CE1と記載)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。
The hair catcher 10 has a region where the standing wall portion 50 is not provided on the bathtub side in order to make it easier to place the hand on the handle portion 122 when removing the cover 120, and the bathtub side edge portion of the upper drainage outflow portion 30. 30b is made into the shape connected to the bathtub side edge part of hair catcher itself. Here, most of the drainage from the washing station W1 flows into the drainage basin 112 from the washing station W1 side, so that the hair catcher 10 is compared with the drainage that flows into the temporary water retaining unit 20 from the flange portion 70 via the inclined portion 60. There is little drainage flowing directly into the upper drainage outlet 30 from the bathtub side edge.
By the standing wall portion 50 and the flange portion 70 described above, the waste water from the washing place W1 is mainly guided to the inflow port 56. Since the flange portion 70 has a gradient descending toward the inflow port 56, the flow rate of the drainage to be guided is increased and the drainage is guided to the inclined portion 60. The inclined portion 60 temporarily holds water toward a position shifted in the horizontal direction from the center of gravity CE1 of the lower drainage outflow portion projected onto the virtual horizontal plane (hereinafter referred to as the center of gravity CE1 of the lower drainage outflow portion). Guide to section 20.

なお、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を排水桝段部114に載置し、該ヘアキャッチャー10の隅部にカバー120を載置することにより、形成される。
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. Formed by fixing the main body 130 to each other, attaching the sealing tube 150 to the fastening flange 140, placing the hair catcher 10 on the drainage drainage step 114, and placing the cover 120 on the corner of the hair catcher 10 Is done.

(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に流入し、主にヘアキャッチャーフランジ部70上へ流下する。ここで、図4の左側にある隅部76に流下した排水は第一の領域72へ流れ、同図の右側にある隅部77に流下した排水は領域72,74の下流部から速やかに流入口56へ流れる。第一の領域72上の排水は、第一の分割立壁部52に沿って左回りに案内された後、流入口56へ流れる。図5(a)に示すように第一の領域72の洗い場W1側の部分が流入口56に向けて下がる勾配を有しているので、洗い場からの排水が流速を高めながら傾斜部60へ流れる。第二の領域74上の排水は、第二の分割立壁部54に沿って洗い場W1側へ案内された後、傾斜部60へ流れる。ここで、図5に示すように流入口56に向かって下がる部分において第二の領域74の下り勾配G2が第一の領域72の下り勾配G1よりも小さいので、第二の領域74上の排水は、一時保水部内の旋回流の回転方向D1と逆方向から案内されるものの、第一の領域72へ流れ難く、傾斜部60で該旋回流を減衰させにくい方向へ向きが変えられる。また、図4に示す排水の流れ方向D13に沿った傾斜部60の傾斜が排水の流れ方向D11,D12に沿った領域72,74の傾斜よりも大きいので、傾斜部60に流入した排水は一時保水部20内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。
(2) Action and effect of hair catcher:
Next, the operation and effect of the hair catcher 10 will be described.
The wastewater generated at the washing place W1 flows into the drainage basin 112 from the periphery of the cover 120 and flows down mainly onto the hair catcher flange portion 70. Here, the drainage flowing down to the corner 76 on the left side of FIG. 4 flows to the first region 72, and the drainage flowing down to the corner 77 on the right side of FIG. It flows to the inlet 56. The drainage on the first region 72 is guided counterclockwise along the first divided standing wall 52 and then flows to the inlet 56. As shown in FIG. 5A, since the portion of the first region 72 on the washing station W1 side has a gradient that decreases toward the inlet 56, drainage from the washing site flows to the inclined portion 60 while increasing the flow velocity. . The drainage on the second region 74 flows to the inclined portion 60 after being guided along the second divided standing wall portion 54 toward the washing place W1. Here, as shown in FIG. 5, since the downward gradient G2 of the second region 74 is smaller than the downward gradient G1 of the first region 72 in the portion descending toward the inflow port 56, the drainage on the second region 74. Is guided in the direction opposite to the rotational direction D1 of the swirling flow in the temporary water retaining portion, but is difficult to flow to the first region 72 and is changed in a direction in which the swirling flow is not easily attenuated by the inclined portion 60. Further, since the slope of the inclined portion 60 along the drainage flow direction D13 shown in FIG. 4 is larger than the slope of the regions 72 and 74 along the drainage flow directions D11 and D12, the wastewater flowing into the slope 60 is temporarily The speed is increased toward the inside of the water retention unit 20. For this reason, a swirl flow can be generated effectively even with a small amount of drainage.

傾斜部60を流下した排水は、下部排水流出部22の重心CE1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に流入し、該一時保水部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。ここで、フランジ部70により流速を高めた排水が流入口56から一時保水部20へ導入されるので、一時保水部20内の排水の流れが一定となる。従って、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6(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効果的に集まり、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。   The drainage flowing down the inclined portion 60 flows into the concave temporary water retaining portion 20 toward a position shifted in the horizontal direction from the center of gravity CE1 of the lower drainage outflow portion 22, and left while being temporarily retained by the temporary water retaining portion 20. It turns around and flows out from the lower drainage outflow part 22 downward. 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 <b> 1 that passes through the lower drainage outlet 22 and is directed vertically. Here, since the waste water whose flow velocity is increased by the flange portion 70 is introduced from the inflow port 56 to the temporary water retention portion 20, the flow of the waste water in the temporary water retention portion 20 becomes constant. Accordingly, in the swirl of the drainage temporarily accumulated in the temporary water retention unit 20, the foreign matter such as the hair H1 swirls and gathers effectively while floating as shown in FIG. The outflow of hair H1 and the like from 22 is 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.

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。図6(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. FIG. 6B shows that the drainage has risen to the position L1 beyond the upper edge portion 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6(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。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。
図8(c)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つ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、排水が徐々に下部排水流出部22を通過するので、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 retention 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. 6 (c). It remains in the water retention unit 20. When discarding the collected hair or the like, the hair catcher 10 may be removed and turned over after removing the cover 120 from the drain 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.
If the drainage is allowed to pass through the hair catcher quickly as in the conventional example shown in FIG. 8 (c), it will be difficult for the hair etc. to get entangled with the hair catcher. Since the wastewater gradually passes through the lower drainage outflow portion 22, good hair removability can be obtained and cleaning is easy.

また、図8(a)〜(c)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、上部排水流出部30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)〜(c)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)(b)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(c)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。
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。
Also, as in the conventional example shown in FIGS. 8 (a) to 8 (c), when all the waste water from the washing place passes through the entire hair catcher at once, the hair etc. adheres to the entire hair catcher and is easily clogged. Since the hair catcher 10 does not directly flow into the upper drainage outflow portion 30, the hair catcher 10 can obtain a stable drainage capacity by preventing the upper drainage outflow portion 30 from being blocked.
Furthermore, in the conventional example shown in FIGS. 8A to 8C, 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. 8 (a) and 8 (b), the drainage capacity is limited by all drainage from the washing place passing through the drainage amount adjusting component 904. According to the hair catcher 10, however, Since there is no need to limit the capacity, a stable drainage capacity can be obtained. In addition, in the conventional example shown in FIG. 8C, bathtub drainage is necessary to generate eddy currents, but this hair catcher 10 is good only by draining from a washroom such as a washroom shower without using bathtub drainage. Hair removability can be obtained.
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.

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つ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 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。
洗い場及び浴槽に対するヘアキャッチャーの向きは、上述した実施形態に限定されず、例えば、鉛直に向いた仮想の回転軸AX1を中心として360°全ての向きに変更可能である。従って、洗い場からの排水を一時保水部へ通す流入口は、上述した実施形態のように洗い場側に配置される以外にも、浴槽側に配置されてもよいし、洗い場側と浴槽側との中間的な位置等に配置されてもよい。
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。
上記一時保水部は、半球状や、上下逆の円錐の頂点を丸くしたような凹状に形成してもよい。すると、一時保水部内で排水が旋回流になり易くなると考えられ、毛髪等をよりまとめて捨てやすくすることができると考えられる。
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.
The direction of the hair catcher with respect to the washing area and the bathtub is not limited to the above-described embodiment, and can be changed to all 360 degrees around a virtual rotation axis AX1 that is vertically oriented, for example. Therefore, the inflow port through which the wastewater from the washing place is passed to the temporary water holding part may be arranged on the bathtub side in addition to being arranged on the washing area side as in the above-described embodiment, or between the washing area side and the bathtub side. It may be arranged at an intermediate position or the like.
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 temporary water retaining portion may be formed in a hemispherical shape or a concave shape in which the top of an inverted cone is rounded. Then, it is thought that drainage becomes a swirl flow easily in the temporary water retention part, and it is considered that hair and the like can be more easily discarded.
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.

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.

また、図7に示すヘアキャッチャー210のように、一時保水部220の底に上方へ突出した凸部224が設けられてもよい。この一時保水部220は、凸部224の周囲に複数の水抜き孔223を有する下部排水流出部222が設けられている。この変形例でも、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、毛髪等がまとまった状態で一時保水部内に残存して、良好な毛髪除去性及び安定した排水能力を得る効果が得られる。
さらに、一時保水部の底に設けられる凸部は、上方へ膨出した部位等でもよい。
Moreover, the convex part 224 which protruded upwards may be provided in the bottom of the temporary water retention part 220 like the hair catcher 210 shown in FIG. The temporary water retaining part 220 is provided with a lower drainage outflow part 222 having a plurality of drain holes 223 around the convex part 224. Even in this modified example, the hair etc. floats and collects in the drainage water temporarily stored in the temporary water retention part, and remains in the temporary water retention part in a state where the hair etc. is gathered, and has good hair removability and stable drainage. The effect of acquiring ability is obtained.
Furthermore, the convex part provided at the bottom of the temporary water retaining part may be a part that bulges upward.

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。
また、本発明は、上述した実施形態や変形例に限られず、上述した実施形態および変形例の中で開示した各構成を相互に置換したり組み合わせを変更したりした構成、公知技術並びに上述した実施形態および変形例の中で開示した各構成を相互に置換したり組み合わせを変更したりした構成、等も含まれる。
