ところで、排水口部材の下流側の排水管として、サイホン排水管を用いる場合がある。サイホン排水管は、サイホン力が発生するまでにタイムラグがあり、サイホン力が発生していない初期段階では、サイホン力が発生した場合に比較して単位時間当たりの排水量が少ない。
排水口部材の側面の開口に平らなメッシュ部材を取り付けた場合、メッシュ部材が排水の流れの抵抗となり、大量の排水を一度にシンクに流した場合、サイホン排水管にサイホン力が発生するまでの間、排水口部材から排水が溢れる場合がある。
By the way, a siphon drainage pipe may be used as a drainage pipe on the downstream side of the drainage port member. The siphon drainage pipe has a time lag until the siphon force is generated, and in the initial stage where the siphon force is not generated, the amount of drainage per unit time is smaller than when the siphon force is generated.
When a flat mesh member is attached to the side opening of the drainage port member, the mesh member resists the flow of drainage, and when a large amount of drainage flows into the sink at one time, siphon force is generated in the siphon drainage pipe In the meantime, drainage may overflow from the drainage port member.

本発明は上記事実を考慮し、排水口部材から排水が溢れることを抑制可能な排水口メッシュ部材の提供を目的とする。   An object of the present invention is, in consideration of the above-mentioned fact, to provide a drainage mesh member capable of suppressing the overflow of drainage from the drainage member.

請求項1に記載の排水口メッシュ部材は、排水口部材の排水流出口に取り付けられ、一方向から見て湾曲することで前記排水流出口の開口面積よりも面積が大きく設定されたメッシュ部を備えている。   The drain mesh member according to claim 1 is attached to the drainage outlet of the drainage member, and the mesh portion whose area is set larger than the opening area of the drainage outlet by curving as viewed from one direction Have.

請求項1に記載の排水口メッシュ部材では、排水が通過するメッシュ部が一方向から見て湾曲しており、これによってメッシュ部の面積が、排水流出口の開口面積よりも大きくなっている。このため、メッシュ部が湾曲していない場合に比較して、迅速に排水を通過させることができ、排水口部材から排水が溢れることを抑制することが可能となる。   In the drainage port mesh member according to claim 1, the mesh portion through which the drainage passes is curved as viewed from one direction, whereby the area of the mesh portion is larger than the opening area of the drainage outlet. For this reason, compared with the case where a mesh part is not curving, drainage can be made to pass rapidly, and it becomes possible to control that drainage overflows from a drainage port member.

請求項2に記載の発明は、請求項1に記載の排水口メッシュ部材において、前記メッシュ部は、設置状態で鉛直方向から見て水平方向に湾曲している。   According to a second aspect of the present invention, in the outlet mesh member according to the first aspect, the mesh portion is curved in the horizontal direction when viewed from the vertical direction in the installed state.

請求項2に記載の排水口メッシュ部材では、メッシュ部が設置状態で鉛直方向から見て水平方向に湾曲しているため、鉛直方向に湾曲している場合に比較して、メッシュ部の表面を清掃し易い。なお、メッシュ部が鉛直方向に湾曲していると、下側が狭くなり、例えば、柄付きブラシのブラシ(清掃毛束)が届かない部分がでてきて清掃し難くなる。   In the drainage port mesh member according to claim 2, since the mesh portion is curved in the horizontal direction when viewed from the vertical direction in the installed state, the surface of the mesh portion is compared with the case where the mesh portion is curved in the vertical direction. Easy to clean. When the mesh portion is curved in the vertical direction, the lower side becomes narrow, and for example, a portion to which the brush (cleaning bristle bundle) of the brush with a handle does not come out and it becomes difficult to clean.

請求項3に記載の発明は、請求項1または請求項2に記載の排水口メッシュ部材において、前記メッシュ部は、排水方向上流側に向けて凸状に湾曲している。   The invention according to claim 3 is the outlet mesh member according to claim 1 or 2, wherein the mesh portion is convexly curved toward the upstream side in the drainage direction.

請求項3に記載の排水口メッシュ部材では、メッシュ部が、排水方向上流側に向けて凸状に湾曲している。言い換えれば、メッシュ部が、排水の流入側に向けて凸状に湾曲している。このため、メッシュ部が、排水方向上流側に向けて凹状に湾曲している場合に比較して、清掃がし易い。   In the drainage port mesh member according to claim 3, the mesh portion is convexly curved toward the drainage direction upstream side. In other words, the mesh portion is convexly curved toward the inflow side of the drainage. For this reason, it is easier to clean as compared with the case where the mesh portion is concavely curved toward the upstream side in the drainage direction.

請求項4に記載の発明は、請求項1〜請求項3の何れか1項に記載の排水口メッシュ部材において、水平方向に向けて開口する前記排水流出口に取り付けられ、前記メッシュ部は水平方向に向けて形成され、前記メッシュ部の上側には、上方から流下する排水を前記メッシュ部の正面とは異なる方向へ流すリブが設けられている。   The invention according to claim 4 is the drainage mesh member according to any one of claims 1 to 3, which is attached to the drainage outlet opening in the horizontal direction, and the mesh portion is horizontal The rib is formed in the direction, and on the upper side of the mesh part, the draining water flowing down from above is made to flow in a direction different from the front of the mesh part.

請求項4に記載の排水口メッシュ部材は、排水口部材の水平方向に向けて開口する排水流出口に取り付けられる。一例として、シンクに排水が流されると、該排水は、シンクの底部、及び排水口部材の側面を伝わって排水口部材の底部に向けて流れ、排水口部材の底部に到った排水が排水流出口を介して排水口部材の外部へと排出される。   The outlet mesh member according to claim 4 is attached to a drainage outlet opening in the horizontal direction of the outlet member. As an example, when the drain is drained to the sink, the drain flows along the bottom of the sink and the side surface of the drain member toward the bottom of the drain member, and the drain drained to the bottom of the drain member drains It is discharged to the outside of the drainage port member through the outflow port.

排水口メッシュ部材には、メッシュ部の上側に、上方から流下する排水をメッシュ部の正面とは異なる方向へ流すリブが設けられている。このため、多量の排水がシンクに流された場合、排水口部材の側面を伝わって流下する排水が流出口を塞がないように、リブがメッシュ部の正面とは異なる方向へ分散させる。これにより、排水口部材の底部の排水をスムーズに排水流出口に流入させて排水口部材の外部へ排出させることができる。
これにより、例えば、溜め流し排水をしたときのように、一度に多量の排水をシンクに流した場合であっても、排水口部材から排水が溢れ出ることを抑制することができる。
The drainage port mesh member is provided with a rib on the upper side of the mesh portion, which allows the drainage flowing down from above to flow in a direction different from the front of the mesh portion. For this reason, when a large amount of drainage flows into the sink, the ribs are dispersed in a direction different from the front of the mesh portion so that the drainage flowing down along the side surface of the drainage member does not block the outlet. As a result, the drainage on the bottom of the drainage member can be smoothly made to flow into the drainage outlet and be discharged out of the drainage member.
As a result, for example, even when a large amount of drainage is made to flow to the sink at one time, as in the case of draining the drainage, it is possible to suppress the drainage from overflowing from the drainage port member.

請求項5に記載の発明は、請求項1〜請求項4の何れか1項に記載の排水口メッシュ部材において、前記メッシュ部の孔は、複数の辺からなる多角形状とされ、一方の辺と他方の辺とで成す角度が鈍角に設定されている。   The invention according to a fifth aspect is the drainage mesh member according to any one of the first to fourth aspects, wherein the hole of the mesh portion has a polygonal shape including a plurality of sides, and one side The angle formed by and the other side is set to an obtuse angle.

請求項5に記載の排水口メッシュ部材では、メッシュ部の孔が、複数の辺からなる多角形状とされ、一方の辺と他方の辺とで成す角度が鈍角、言い換えれば90度を超える角度に設定されているため、メッシュ部の孔の角部が90度以下の鋭角である場合に比較して、排水中の異物が角部に引っ掛かり難い。   In the drainage port mesh member according to claim 5, the hole of the mesh portion is formed in a polygonal shape having a plurality of sides, and an angle formed by one side and the other side is an obtuse angle, in other words, an angle exceeding 90 degrees. Since the setting is made, foreign matter in the drainage is less likely to be caught by the corner compared to the case where the corner of the hole of the mesh portion has an acute angle of 90 degrees or less.

請求項6に記載の発明は、請求項5に記載の排水口メッシュ部材において、前記一方の辺と前記他方の辺とで形成される角部は湾曲している。   The invention according to a sixth aspect is the drainage mesh member according to the fifth aspect, wherein a corner formed by the one side and the other side is curved.

請求項6に記載の排水口メッシュ部材では、メッシュ部の孔の一方の辺と他方の辺とで形成される角部が湾曲しているため、湾曲していない場合に比較して排水中の異物が角部に引っ掛かり難い。   In the drainage port mesh member according to claim 6, since the corner portion formed by one side and the other side of the hole of the mesh portion is curved, it is in drainage compared with the case where it is not curved. Foreign matter is hard to get caught in the corner.

請求項7に記載の発明は、請求項1〜請求項6の何れか1項に記載の排水口メッシュ部材において、前記排水流出口に取り付けられる筒部を備え、前記筒部の排水方向上流側の端縁にメッシュ部が設けられ、前記メッシュ部により前記端縁の開口が覆われている。   The invention according to claim 7 is the drainage mesh member according to any one of claims 1 to 6, further comprising: a cylindrical portion attached to the drainage outlet, wherein the drainage direction upstream side of the cylindrical portion A mesh portion is provided at the edge of the frame, and the mesh portion covers the opening of the edge.

図1〜図13を用いて、本発明の一実施形態に係る排水口メッシュ部材48をについて説明する。図1は、本発明の一実施形態に係る排水口メッシュ部材48を用いたサイフォン排水システム10の全体構成を示す概略図である。   The drainage port mesh member 48 which concerns on one Embodiment of this invention is demonstrated using FIGS. FIG. 1 is a schematic view showing the overall configuration of a siphon drainage system 10 using a drainage mesh member 48 according to an embodiment of the present invention.

(サイフォン排水システムの構成)
サイフォン排水システム10は、サイフォン力を利用して水廻り器具からの排水を効率よく排出する排水システムである。本実施形態では、サイフォン排水システムを、複数階で構成された集合住宅に用いた例について説明する。なお、サイフォン排水システムは、集合住宅に好適に用いられるが、集合住宅以外の戸建て住宅や工場等にも用いることができる。
(Configuration of siphon drainage system)
The siphon drainage system 10 is a drainage system that efficiently discharges the drainage from the water pouring implement using siphon power. In the present embodiment, an example in which a siphon drainage system is used for a multi-storey housing complex will be described. In addition, although a siphon drainage system is used suitably for collective housing, it can be used also for single-family homes, factories, etc. other than collective housing.

図1に示すように、本実施形態に係るサイフォン排水システム10は、排水を下方へ流す排水立て管12を備えている。この排水立て管12は、集合住宅の上下方向(縦方向)に延設され、集合住宅の各階の床スラブ14を貫いている。
集合住宅の各階の各戸には、排水がなされる水廻り器具16が設けられている。水廻り器具16は、例えば、台所流し(シンク)で構成されている。なお、水廻り器具16としては、台所流しに限らず、洗面台、洗濯機、ユニットバス及びトイレ等のいずれかで構成されていてもよい。
As shown in FIG. 1, the siphon drainage system 10 which concerns on this embodiment is provided with the drainage stack pipe 12 which pours drainage down. The drainage pipe 12 is extended in the vertical direction (longitudinal direction) of the collective housing, and penetrates the floor slabs 14 of each floor of the collective housing.
A watering device 16 for draining is provided on each floor of each floor of the housing complex. The watering device 16 is configured of, for example, a kitchen sink. In addition, as a watering apparatus 16, you may be comprised not only in a kitchen sink but in any one of a washbasin, a washing machine, a unit bath, a toilet, etc.

水廻り器具16の底部に形成された排水口17には排水口部材18が取り付けられており、排水口部材18の排水方向下流側には、配管20、汚臭やガス等の逆流を防止するためのS字トラップ22、配管24、及びサイフォン排水管26に接続されている。   A drainage port member 18 is attached to the drainage port 17 formed at the bottom of the watering device 16, and the pipe 20 prevents the backflow of dirty odor, gas, etc. on the downstream side of the drainage port 18 in the drainage direction. It is connected to the S-shaped trap 22, the piping 24, and the siphon drainage pipe 26.

サイフォン排水管26は、床スラブ14上に無勾配で設置されて横方向に延びる横引き管28と、この横引き管28と連通して排水立て管12に沿って下方へ延びる竪管30と、を有している。   The siphon drainage pipe 26 is installed on the floor slab 14 in an inclined manner and extends laterally, and a transverse pipe 30 communicating with the transverse pipe 28 and extending downward along the drainage pipe 12. ,have.

なお、横引き管28は、若干の勾配や逆勾配があってもよく、傾斜して横方向に配置される構成であってもよい。竪管30は、排水立て管12に配置された合流継手32に接続されており、合流継手32を介して排水立て管12と連通している。   In addition, the traverse pipe 28 may have a slight slope or a reverse slope, or may be configured to be disposed in an inclined lateral direction. The bushing 30 is connected to a joint joint 32 disposed in the drainage pipe 12 and is in communication with the drainage pipe 12 via the joint joint 32.

横引き管28は、配管24からの排水を横方向へ流し、竪管30は、横引き管28からの排水を流下させることによりサイフォン力を発生させる。横引き管28内の排水には、竪管30で発生するサイフォン水頭Hsのエネルギーにより、排水方向へ向かうサイフォン力が作用される。   The transverse draw pipe 28 drains the drainage from the pipe 24 in the lateral direction, and the weir 30 generates a siphon force by causing the drainage from the transverse draw pipe 28 to flow down. The siphon force directed to the drainage direction is exerted on the drainage in the lateral pulling pipe 28 by the energy of the siphon water head Hs generated in the weir 30.

また、横引き管28及び竪管30は細くなれば、排水が満水の状態になりサイフォン力が発生しやすい一方、排水処理量が低下する。従って、横引き管28及び竪管30は、サイフォン力の発生のしやすさ及び必要な排水処理量を考慮した上で管の内径が設定され、例えば、20Aにされている。   In addition, if the horizontal pulling pipe 28 and the weir 30 become thinner, the drainage becomes full of water, so that siphon force tends to occur, but the amount of drainage treated decreases. Therefore, in consideration of the ease of occurrence of the siphon force and the required amount of waste water to be treated, the inner diameter of the lateral pulling pipe 28 and the tapping pipe 30 is set to, for example, 20A.

(排水口部材の構成)
図2に示すように、排水口部材18は、円筒部34と、円筒部34の下部を塞ぐ底部36と、円筒部34の上部に形成されるフランジ38と、円筒部34の底部側の側部に形成される管状の排出部40とを備えている。なお、円筒部34の上側の開口部分は、水廻り器具16の排水が流入する流入口35である。本実施形態の排水口部材18の円筒部34は、径寸法よりも高さ寸法が大きく形成されることで、一般の排水口部材よりも深さが深く、かつ容積が大きく形成されている。また、排出部40は、円筒部34よりも小径である。排水口部材18の底部36に排水が溜まらないように、排出部40の内周面の下端と、円筒部34の底部36の上面とは高さが一致していることが好ましい。
(Structure of drain member)
As shown in FIG. 2, the drainage port member 18 has a cylindrical portion 34, a bottom portion 36 closing a lower portion of the cylindrical portion 34, a flange 38 formed on the cylindrical portion 34, and a side of the cylindrical portion 34 on the bottom side. And a tubular discharge part 40 formed in the part. The upper opening of the cylindrical portion 34 is an inlet 35 through which the drainage of the water-pouring device 16 flows. The cylindrical portion 34 of the drainage port member 18 of the present embodiment is formed to be larger in height than the diameter dimension, and thus is formed deeper than the general drainage port member and has a large volume. Further, the discharge part 40 has a smaller diameter than the cylindrical part 34. It is preferable that the lower end of the inner peripheral surface of the discharge part 40 and the upper surface of the bottom part 36 of the cylindrical part 34 have the same height so that drainage does not collect in the bottom part 36 of the drainage port member 18.

円筒部34の深さは、175〜225mmの範囲内とすることが好ましい。
円筒部34の容積は、2000〜3000cmとすることが好ましい。
The depth of the cylindrical portion 34 is preferably in the range of 175 to 225 mm.
The volume of the cylindrical portion 34 is preferably 2000 to 3000 cm 3 .

排水口部材18のフランジ38と水廻り器具16の底部との間には、パッキン42が挟まれており、円筒部34の外周の一部に形成された雄螺子44に環状のナット46が締め込まれることで排水口部材18が水廻り器具16に取り付けられている。   A packing 42 is sandwiched between the flange 38 of the outlet member 18 and the bottom of the watering device 16, and an annular nut 46 is tightened on a male screw 44 formed on a part of the outer periphery of the cylindrical portion 34. The outlet member 18 is attached to the watering device 16 by being inserted.

(排水口メッシュ部材の構成)
円筒部34の側面における排出部40の開口部分である排水流出口40Aには、図3〜図11に示す排水口メッシュ部材48が挿入されている。排水口メッシュ部材48は、排出部40の内部に配置される筒部の一例としての円筒状の筒状本体50を備えている。

The drainage port mesh member 48 includes a cylindrical cylindrical main body 50 as an example of a cylindrical portion disposed inside the discharge portion 40.

図8の上面図で示すように、円筒状の筒状本体50は、排水方向下流側(矢印B方向側)の端縁50Aが軸線CLに対して直角に形成されており、排水方向上流側(矢印F方向側)の端縁50Bが、一方向から見て、例えば、設置状態における鉛直方向から見て排水方向上流側へ向けて凸状となるように湾曲形状に形成されている。なお、端縁50Bは、鉛直方向(湾曲する方向とは直交する方向)には真っ直ぐである(図3,6等参照)。   As shown in the top view of FIG. 8, the cylindrical tubular main body 50 is formed such that the end 50A of the downstream side in the drainage direction (arrow B direction side) is perpendicular to the axis CL, and the upstream side in the drainage direction The edge 50B (on the side of the arrow F) is formed in a curved shape so as to be convex toward the upstream side in the drainage direction when viewed from one direction, for example, viewed from the vertical direction in the installed state. The edge 50B is straight in the vertical direction (the direction orthogonal to the bending direction) (see FIGS. 3 and 6 and the like).

図3に示すように、筒状本体50の排水方向上流側(矢印F方向側)の開口部分は、排水方向上流側へ向けて凸状となるように湾曲形状に形成されたメッシュ部52で覆われている。言い換えれば、湾曲形状に形成されたメッシュ部52の外周部分が、筒状本体50の湾曲形状に形成された端縁50Bに一体的に接合されている。本実施形態の排水口メッシュ部材48は、合成樹脂で容易に成形することができる。   As shown in FIG. 3, the opening portion of the discharge direction upstream side (arrow F direction side) of the cylindrical main body 50 is a mesh portion 52 formed in a curved shape so as to be convex toward the discharge direction upstream side. It is covered. In other words, the outer peripheral portion of the mesh portion 52 formed in a curved shape is integrally joined to the edge 50 B formed in the curved shape of the cylindrical main body 50. The drain mesh member 48 of the present embodiment can be easily formed of synthetic resin.

ここで、メッシュ部52の面積とは、本実施形態では、筒状本体50の裏側から見える部分(図5参照)を、平面状に展開したときの面積(図4の孔54の部分と排水の通過しない部分52Aとを合わせた面積)のことである。   Here, with the area of the mesh portion 52, in this embodiment, the area (see the hole 54 in FIG. 4 and the drainage when the portion (see FIG. 5) seen from the back side of the cylindrical main body 50 is expanded in a planar manner. Of the area 52A together with the non-passing portion 52A.

本実施形態のメッシュ部52には、複数の孔54が形成されている。図4の正面図で示すように、メッシュ部52の孔54は、複数の辺からなる多角形状とされ、互いに隣接する一方の辺と他方の辺とで成す角度θが鈍角に設定されていることが好ましい。本実施形態の孔54は、外周側に配置される一部(54A)を除き、六角形に形成されている。本実施形態では、これらの孔54が蜂の巣状に六角形が隙間無く配置されている。これにより、排水が通過する部分を最大限広くとることができる。   A plurality of holes 54 are formed in the mesh portion 52 of the present embodiment. As shown in the front view of FIG. 4, the hole 54 of the mesh portion 52 is formed in a polygonal shape having a plurality of sides, and an angle θ formed by one side and the other side adjacent to each other is set to an obtuse angle Is preferred. The holes 54 in the present embodiment are formed in a hexagonal shape except for a part (54A) disposed on the outer peripheral side. In the present embodiment, these holes 54 are arranged in a honeycomb shape with no gaps. This makes it possible to maximize the area through which the drainage passes.

図12に示すように、排水口メッシュ部材48の筒状本体50は、軸方向の中央部を境にして排水方向下流側の一部が排出部40に挿入され、排水方向上流側が排水口部材18の円筒部34の内周面から円筒部34の内部に向けて水平方向に突出している。   As shown in FIG. 12, in the cylindrical main body 50 of the drainage port mesh member 48, a part on the downstream side in the drainage direction is inserted into the drainage part 40 with the central portion in the axial direction as a boundary. It projects horizontally from the inner circumferential surface of the 18 cylindrical portion 34 toward the inside of the cylindrical portion 34.

この筒状本体50において、円筒部34の内側に突出している排水方向上流側の部分で、かつ筒状本体50の軸心よりも上側の部分(斜線で示す部分)50Cが、リブに相当している。リブに相当する部分50Cの円筒部34の内周面からの突出長さLに対して特に規定は無いが、装着時に、円筒部34の内周面から5〜25mm程度突出させることが好ましい。リブに相当する部分50Cはメッシュ部52よりも排水方向下流側に突出している。これにより、メッシュ部52を清掃するときに、上から手を伸ばしてもリブに相当する部分50Cが清掃の邪魔になることがない。   In the cylindrical main body 50, a portion on the upstream side in the drainage direction that protrudes to the inside of the cylindrical portion 34, and a portion 50C above the axial center of the cylindrical main body 50 (indicated by hatching) corresponds to a rib. ing. There is no particular limitation on the projection length L of the portion 50C corresponding to the rib from the inner peripheral surface of the cylindrical portion 34, but it is preferable to project about 5 to 25 mm from the inner peripheral surface of the cylindrical portion 34 at the time of mounting. The portion 50C corresponding to the rib protrudes downstream in the drainage direction with respect to the mesh portion 52. As a result, when the mesh portion 52 is cleaned, the portion 50C corresponding to the rib does not disturb the cleaning even when the hand is extended from above.

(作用、効果)
次に、本実施形態に係る排水口メッシュ部材48の作用を説明する。
本実施形態に係るサイフォン排水システム10では、水周り器具16の排水は、排水口部材18、配管20、S字トラップ22、及び配管24を介してサイフォン排水管26へ流れ込む。排水は、横引き管28内を横方向へ流れ、その後、竪管30を流下し、竪管30におけるサイフォン水頭Hsのポテンシャルエネルギーにより、サイフォン力が発生する。このサイフォン力により、排水が誘導されて排水の排出が促進される。
(Action, effect)
Next, the operation of the drainage port mesh member 48 according to the present embodiment will be described.
In the siphon drainage system 10 according to the present embodiment, drainage of the water-surrounding device 16 flows into the siphon drainage pipe 26 via the drainage port member 18, the piping 20, the S-shaped trap 22, and the piping 24. The drainage flows in the lateral direction in the horizontal pulling pipe 28 and then flows down the suction pipe 30 and the siphon force is generated by the potential energy of the siphon head Hs in the suction pipe 30. The siphon force induces drainage and promotes drainage.

本実施形態の排水口メッシュ部材48は、排水Wが通過するメッシュ部52が湾曲しており、メッシュ部52の面積が、排出部40の排水流出口40Aの開口面積よりも大きくなっているため、メッシュ部52が湾曲していない場合(平坦な場合)に比較して、迅速に排水Wを通過させることができる。これにより、排水口部材18から排水が溢れることを抑制できる。   In the drainage port mesh member 48 of the present embodiment, the mesh portion 52 through which the drainage W passes is curved, and the area of the mesh portion 52 is larger than the opening area of the drainage outlet 40A of the drainage portion 40. The drainage W can be rapidly passed through as compared with the case where the mesh portion 52 is not curved (flat). Thereby, overflow of drainage from the drainage port member 18 can be suppressed.

また、本実施形態の排水口メッシュ部材48は、排水口部材18の円筒部34の内側へ向けて突出する部分50Cが、円筒部34の側面に開口する排水流出口40Aの正面側を上側から覆う様に設けられているため、多量の排水Wが水周り器具16に流された場合であっても、排水口部材18の円筒部34の内側面を伝わって流下する排水Wが排出部40の排水流出口40Aを塞がないように、流下する排水Wを図4、及び図13の矢印Aで示すようにリブ60で分散させることができる。言い換えれば、排出部40の排水流出口40Aの正面側において、排出部40の排水流出口40Aに向けて流れ込もうとする排水W(図13の矢印B方向)に対して、円筒部34の内側面を伝わって流下する排水Wが干渉しないように本発明のリブに相当する部分50Cは流下する排水Wの流れの向きを変更している。これにより、排水口部材18の円筒部34の底部の排水Wを、スムーズに排出部40に流入させて排水口部材18の外部へ排出させることができる。   Further, in the drainage port mesh member 48 of the present embodiment, the portion 50C of the drainage port member 18 projecting toward the inside of the cylindrical portion 34 is open from the upper side on the front side of the drainage outlet 40A opened in the side surface of the cylindrical portion 34 Since it is provided so as to cover, even when a large amount of drainage W is caused to flow to the water surrounding tool 16, the drainage W flowing down along the inner side surface of the cylindrical portion 34 of the drainage port member 18 is discharged. The drain water W flowing down can be dispersed by the rib 60 as shown by the arrow A in FIG. 4 and FIG. 13 so as not to block the drainage outlet 40A. In other words, on the front side of the drainage outlet 40A of the discharge part 40, the drainage W (in the direction of the arrow B in FIG. 13) which is going to flow toward the drainage outlet 40A of the discharge part 40 The portion 50C corresponding to the rib of the present invention changes the flow direction of the draining water W so that the drainage W flowing down along the inner surface does not interfere. Thus, the drainage W on the bottom of the cylindrical portion 34 of the drainage member 18 can be smoothly made to flow into the drainage portion 40 and be discharged to the outside of the drainage member 18.

これにより、例えば、溜め流し排水をしたときのように、一度に多量の排水を水周り器具16に流した場合であっても、排水口部材18からシンク内へ排水Wが溢れ出ることを抑制することができる。   As a result, for example, even when a large amount of drainage is flowed to the fixture 16 at one time, as in the case of draining the sump, drainage W is prevented from overflowing from the drainage port member 18 into the sink can do.

また、排水口部材18の内部に流入した排水Wの水位の上昇を抑えることができるので、図13の矢印Cで示すように、下流側の配管内の空気を、排水口メッシュ部材48の上側を介して排水口部材18の内方へ向けてスムーズに排出させることができる。これにより、排水Wをよりスムーズに排水口部材18の外部へ排出させることができる。   Further, since the rise of the water level of the drainage W which has flowed into the inside of the drainage port member 18 can be suppressed, as shown by the arrow C in FIG. Can be smoothly discharged toward the inside of the drainage port member 18 via the Thus, the drainage W can be discharged to the outside of the drainage port member 18 more smoothly.

排水口メッシュ部材48のメッシュ部52は、排水口部材18の内部に向けて水平方向のみに湾曲して凸状に突出しており、かつ、鉛直方向(湾曲する方向とは直交する方向)には真っ直ぐで、更には、筒状本体50の排水方向上流側の端縁50Bに一体的に設けられている。このため、排水口部材18を上から見た時に、メッシュ部52に影になるところが無い、即ち、上から見た時に異物が隠れるところが無く、メッシュ部52に付着した異物を、排水口メッシュ部材48を取り外すことなく排水口部材18の上側から容易に清掃することができる。   The mesh portion 52 of the drainage port mesh member 48 is curved only in the horizontal direction toward the inside of the drainage port member 18 and protrudes in a convex shape, and in the vertical direction (direction orthogonal to the curving direction) It is provided integrally with the end edge 50 </ b> B of the cylindrical main body 50 on the upstream side in the drainage direction. For this reason, when the drainage port member 18 is viewed from above, there is no shadow on the mesh portion 52, that is, no foreign matter is hidden when viewed from above, and the foreign matter attached to the mesh portion 52 is a drainage port mesh member It can be easily cleaned from the upper side of the outlet member 18 without removing the 48.

メッシュ部52の孔54は、極一部を除き6角形であり、一方の辺と他方の辺とで成す角度が鈍角(一例として120度)に設定されているため、一方の辺と他方の辺とで成す角度が鋭角である場合に比較して、排水中の異物が角部に引っ掛かり難い。また、孔54の形状を6角形にして蜂の巣状に配置することで、孔54と孔54との間の部分、言い換えれば、排水の通過しない部分52A(図4参照)の面積を最小限にすることができ、排水Wの通過抵抗を低減することができる。   The hole 54 of the mesh portion 52 is hexagonal except for a part of the pole, and the angle formed by one side and the other side is set to an obtuse angle (120 degrees as an example). Foreign matter in the drainage is less likely to be caught in the corner compared to the case where the angle formed by the side is acute. Also, by arranging the hole 54 in a hexagonal shape and arranging it in a honeycomb shape, the area between the hole 54 and the hole 54, in other words, the area 52A (see FIG. 4) through which drainage does not pass is minimized. It is possible to reduce the passage resistance of the drainage W.

本実施形態の排水口メッシュ部材48は、排出部40に対して着脱可能とされているので、排水口メッシュ部材48を外して清掃することもできる。なお、排水口メッシュ部材48は、排出部40から取り外せない様に排出部40に図示しない爪、接着剤等で固定してもよく、排水口部材18に一体的に設けてもよい。   The drain mesh member 48 of the present embodiment is detachable from the discharge part 40, so the drain mesh member 48 can be removed for cleaning. The drainage port mesh member 48 may be fixed to the drainage portion 40 with a claw, an adhesive or the like (not shown) so as not to be removed from the drainage portion 40 or may be integrally provided in the drainage port member 18.

本実施形態の排水口メッシュ部材48は、取り付け状態で、メッシュ部52が水平方向に湾曲していたが、メッシュ部52が鉛直方向に湾曲するように排出部40に取り付けることもできる。   Although the mesh portion 52 is curved in the horizontal direction in the attached state, the drainage mesh member 48 of the present embodiment can be attached to the discharge portion 40 so that the mesh portion 52 is curved in the vertical direction.

本実施形態の排水口メッシュ部材48は、図6に示すように、メッシュ部52が曲率半径Rとされた円弧形状に湾曲しているが、メッシュ部52は、曲率半径の異なる複数の円弧で形成された湾曲形状であってもよく、複数の直線を連結して湾曲形状に近似させた形状であってもよい。   As shown in FIG. 6, the mesh portion 52 is curved in an arc shape having a radius of curvature R as shown in FIG. 6, but the mesh portion 52 is a plurality of arcs with different radii of curvature, as shown in FIG. 6. It may be a formed curved shape, or may be a shape in which a plurality of straight lines are connected to approximate a curved shape.

本実施形態の排水口メッシュ部材48では、筒状本体50の側面に孔が形成されていないが、一例として、図13に左上がりの斜線で示す部分(筒状本体50の中心軸よりも下側で、排水口部材18の円筒部34から突出している部分)50Dに、メッシュ部52の孔54と同様の孔を形成してもよい。これにより、排水口メッシュ部材48において、排水Wを通過させる部分を増やすことができ、より迅速に排水を行うことが可能となる。   In the drainage port mesh member 48 of the present embodiment, no hole is formed on the side surface of the cylindrical main body 50, but as an example, a portion shown by diagonal lines rising to the left in FIG. 13 (below the central axis of the cylindrical main body 50) On the side, a hole similar to the hole 54 of the mesh portion 52 may be formed in the portion 50D of the drainage port member 18 which protrudes from the cylindrical portion 34. Thereby, in the drainage port mesh member 48, the part which lets drainage W pass can be increased, and it becomes possible to drain more rapidly.

本実施形態の排水口メッシュ部材48は、メッシュ部52が排水方向上流側に向けて凸形状となるように湾曲していたが、メッシュ部52が排水方向上流側に向けて凹形状となるように湾曲していてもよい。   The drainage port mesh member 48 of the present embodiment is curved so that the mesh portion 52 is convex toward the upstream side in the drainage direction, but the mesh portion 52 is concaved toward the upstream side in the drainage direction It may be curved.
