Description

本発明は、シンク等の排水口部材に取り付けられる排水口メッシュ部材に関する。 The present invention relates to a drainage port mesh member attached to a drainage port member such as a sink.

キッチのシンクの底部には、シンクに流された排水を排水管へ排出するための凹状の排水口部材が設けられている。排水口部材として、側面に排水管に繋がる開口が設けられている排水口部材（例えば、特許文献１参照）が知られている。
排水口部材には、上部の開口部分を覆うようにゴミ受け用の捕集部材を取り付けているが、排水口部材の側面の開口に、捕集部材で除去できなかった異物を除去する平らなメッシュ部材を取り付ける場合がある。 The bottom of the sink of the kitch is provided with a concave drainage port member for draining the drainage flowing into the sink to the drainage pipe. As a drainage port member, a drainage port member having an opening connected to a drainage pipe on the side surface (see, for example, Patent Document 1) is known.
A collection member for collecting dust is attached to the drainage port member so as to cover the upper opening, but the opening on the side surface of the drainage port member is flat to remove foreign matter that could not be removed by the collection member. A mesh member may be attached.

特開２０１５−１０１８７１号公報Japanese Unexamined Patent Publication No. 2015-101871

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 the drainage pipe on the downstream side of the drainage port member. The siphon drainage pipe has a time lag before the siphon force is generated, and in the initial stage when the siphon force is not generated, the amount of drainage per unit time is smaller than that when the siphon force is generated.
When a flat mesh member is attached to the opening on the side of the drainage port member, the mesh member becomes a resistance to the flow of drainage, and when a large amount of drainage is poured into the sink at once, the siphon force is generated in the siphon drainage pipe. During that time, 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。 In consideration of the above facts, an object of the present invention is to provide a drainage port mesh member capable of suppressing the overflow of drainage from the drainage port member.

請求項１に記載の排水口メッシュ部材は、水平方向に向けて開口する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、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 drainage port mesh member according to claim 1 is attached to a drainage outlet that opens in the horizontal direction, and is curved when viewed from one direction so that the area is set to be larger than the opening area of the drainage outlet. A mesh portion is provided, the mesh portion is formed in the horizontal direction, and a rib is provided on the upper side of the mesh portion to allow drainage flowing down from above to flow in a direction different from the front surface of the mesh portion .

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。
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。
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。 In the drainage port mesh member according to claim 1, the mesh portion through which the drainage passes is curved when viewed from one direction, whereby the area of the mesh portion is larger than the opening area of the drainage outlet. Therefore, as compared with the case where the mesh portion is not curved, the drainage can be passed quickly, and it is possible to prevent the drainage from overflowing from the drainage port member.
The drainage port mesh member is attached to a drainage outlet that opens horizontally in the drainage port member. As an example, when drainage is drained to the sink, the drainage flows toward the bottom of the drainage port member along the bottom of the sink and the side surface of the drainage port member, and the drainage that reaches the bottom of the drainage port member is drained. It is discharged to the outside of the drainage port member through the outlet.
The drainage port mesh member is provided with a rib on the upper side of the mesh portion to allow drainage flowing down from above to flow in a direction different from the front surface of the mesh portion. Therefore, when a large amount of drainage is discharged to the sink, the ribs are dispersed in a direction different from the front surface of the mesh portion so that the drainage flowing down along the side surface of the drainage port member does not block the outlet. As a result, the drainage at the bottom of the drainage port member can be smoothly flowed into the drainage outlet and discharged to the outside of the drainage port member.
This makes it possible to prevent the drainage from overflowing from the drainage port member even when a large amount of drainage is poured into the sink at one time, for example, when the drainage is drained from the pool.

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 the second aspect of the present invention, in the drainage port 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 curved as compared with the case where the mesh portion is curved in the vertical direction. Easy to clean. If the mesh portion is curved in the vertical direction, the lower side becomes narrower, and for example, a portion of the patterned brush (cleaning hair bundle) cannot be reached, making cleaning difficult.

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。 According to the third aspect of the present invention, in the drainage port mesh member according to the first or second aspect, 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 curved in a convex shape toward the upstream side in the drainage direction. In other words, the mesh portion is curved convexly toward the inflow side of the drainage. Therefore, it is easier to clean the mesh portion 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、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 claim 4 is the drainage port mesh member according to any one of claims 1 to 3 , wherein the hole of the mesh portion has a polygonal shape including a plurality of sides, and one side thereof. The angle formed by the other side is set to an obtuse angle.

請求項４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 4, the hole of the mesh portion has a polygonal shape consisting of a plurality of sides, and the angle formed by one side and the other side is an acute angle, in other words, an angle exceeding 90 degrees. Since it is set, foreign matter in the drainage is less likely to be caught in the corner portion as compared with the case where the corner portion of the hole of the mesh portion has an acute angle of 90 degrees or less.

請求項５に記載の発明は、請求項４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。 In the invention according to claim 5, in the drainage port mesh member according to claim 4, the corner portion formed by the one side and the other side is curved.

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 5, since the corner portion formed by one side and the other side of the hole of the mesh portion is curved, it is in the drainage as compared with the case where it is not curved. Foreign matter is hard to get caught in the corners.

請求項６に記載の発明は、請求項１〜請求項５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 6 comprises a cylinder portion attached to the drainage outlet in the drainage port mesh member according to any one of claims 1 to 5, and the upstream side of the cylinder portion in the drainage direction. A mesh portion is provided on the edge of the water, and the mesh portion covers the opening of the edge.

請求項６に記載の排水口メッシュ部材は、筒部を排水流出口に挿入することで、排水口メッシュ部材を排水流出口に取り付けることができる。
また、筒部の排水方向上流側の端縁にメッシュ部が設けられ、メッシュ部により端縁の開口が覆われている、即ち、筒部の内部にメッシュ部が設けられていないので、メッシュ部の表面に付着した異物を簡単に清掃することができる。 In the drainage port mesh member according to claim 6, the drainage port mesh member can be attached to the drainage outlet by inserting the tubular portion into the drainage outlet.
Further, since the mesh portion is provided at the end edge on the upstream side in the drainage direction of the cylinder portion and the opening of the end edge is covered by the mesh portion, that is, the mesh portion is not provided inside the cylinder portion, the mesh portion is provided. Foreign matter adhering to the surface of the can be easily cleaned.

以上説明したように、本発明の排水口メッシュ部材によれば、排水口部材から排水が溢れることを抑制できる、という優れた効果を有する。 As described above, the drainage port mesh member of the present invention has an excellent effect of suppressing the overflow of drainage from the drainage port member.

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。 A drainage port mesh member 48 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 13. FIG. 1 is a schematic view showing an overall configuration of a siphon drainage system 10 using a drainage port 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 drainage from water-related appliances by using siphon force. In this embodiment, an example in which the siphon drainage system is used in an apartment house composed of a plurality of floors will be described. Although the siphon drainage system is preferably used for apartment houses, it can also be used for detached houses and factories other than apartment houses.

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 according to the present embodiment includes a drainage stand pipe 12 for draining drainage downward. The drainage stand pipe 12 extends in the vertical direction (vertical direction) of the apartment house and penetrates the floor slab 14 on each floor of the apartment house.
Each house on each floor of an apartment house is provided with a water supply device 16 for draining water. The water supply device 16 is composed of, for example, a kitchen sink. The water plumbing fixture 16 is not limited to the kitchen sink, and may be composed of a wash basin, a washing machine, a unit bath, a toilet, or the like.

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 water supply device 16, and a pipe 20, a odor, a gas, or the like is prevented from flowing back to the downstream side of the drainage port member 18 in the drainage direction. It is connected to an S-shaped trap 22, a pipe 24, and a siphon drainage pipe 26 for the purpose.

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 includes a horizontal pulling pipe 28 that is installed on the floor slab 14 without a gradient and extends laterally, and a vertical pipe 30 that communicates with the horizontal pulling pipe 28 and extends downward along the drainage vertical 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。 The horizontal pulling pipe 28 may have a slight gradient or a reverse gradient, or may be inclined and arranged in the lateral direction. The vertical pipe 30 is connected to a merging joint 32 arranged in the drainage vertical pipe 12, and communicates with the drainage vertical pipe 12 via the merging 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 horizontal pull pipe 28 causes the drainage from the pipe 24 to flow in the lateral direction, and the vertical pipe 30 causes the drainage from the horizontal pull pipe 28 to flow down to generate a siphon force. A siphon force toward the drainage direction is applied to the drainage in the horizontal pull pipe 28 by the energy of the siphon head Hs generated in the vertical pipe 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。 Further, if the horizontal pulling pipe 28 and the vertical pipe 30 become thin, the drainage becomes full and siphon force is likely to be generated, but the amount of wastewater treated decreases. Therefore, the inner diameter of the horizontal pulling pipe 28 and the vertical pipe 30 is set to, for example, 20A in consideration of the ease of generating siphon force and the required amount of wastewater treatment.

（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 drainage port member)
As shown in FIG. 2, the drainage port member 18 includes a cylindrical portion 34, a bottom portion 36 that closes the lower portion of the cylindrical portion 34, a flange 38 formed on the upper portion of the cylindrical portion 34, and a bottom side side of the cylindrical portion 34. It is provided with a tubular discharge portion 40 formed in the portion. The upper opening of the cylindrical portion 34 is an inflow port 35 into which the drainage of the water supply device 16 flows. The cylindrical portion 34 of the drainage port member 18 of the present embodiment is formed to have a height dimension larger than the diameter dimension, so that the depth is deeper and the volume is larger than that of a general drainage port member. Further, the discharge portion 40 has a smaller diameter than the cylindrical portion 34. It is preferable that the lower end of the inner peripheral surface of the drainage portion 40 and the upper surface of the bottom portion 36 of the cylindrical portion 34 have the same height so that the drainage does not collect in the bottom portion 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、２０００〜３０００ｃｍ３とすることが好ましい。 The depth of the cylindrical portion 34 is preferably within 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 drainage port member 18 and the bottom of the water supply device 16, and an annular nut 46 is fastened to a male screw 44 formed on a part of the outer periphery of the cylindrical portion 34. The drainage port member 18 is attached to the water supply 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。 (Structure of drainage port mesh member)
The drainage port mesh member 48 shown in FIGS. 3 to 11 is inserted into the drainage outlet 40A, which is an opening portion of the drainage portion 40 on the side surface of the cylindrical portion 34. The drainage port mesh member 48 includes a cylindrical main body 50 as an example of a cylindrical portion arranged inside the drainage 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, in the cylindrical main body 50, the edge 50A on the downstream side in the drainage direction (the side in the arrow B direction) is formed at a right angle to the axis CL, and is on the upstream side in the drainage direction. The edge 50B (on the side in the direction of 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, when viewed from the vertical direction in the installed state. The edge 50B is straight in the vertical direction (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 tubular main body 50 on the upstream side in the drainage direction (arrow F direction side) is a mesh portion 52 formed in a curved shape so as to be convex toward the upstream side in the drainage direction. 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 50B formed in the curved shape of the cylindrical main body 50. The drainage port mesh member 48 of the present embodiment can be easily molded with a 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, the area of the mesh portion 52 is, in the present embodiment, the area when the portion visible from the back side of the tubular main body 50 (see FIG. 5) is developed in a plane shape (the portion of the hole 54 in FIG. 4 and drainage). Area including the portion 52A that does not pass through).

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 has a polygonal shape composed of a plurality of sides, and the angle θ formed by one side and the other side adjacent to each other is set to an obtuse angle. Is preferable. The hole 54 of the present embodiment is formed in a hexagonal shape except for a part (54A) arranged on the outer peripheral side. In the present embodiment, these holes 54 are arranged in a honeycomb shape with hexagons without gaps. As a result, the portion through which the drainage passes can be made as wide as possible.

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 tubular main body 50 of the drainage port mesh member 48, a part of the downstream side in the drainage direction is inserted into the discharge part 40 with the central part in the axial direction as a boundary, and the upstream side in the drainage direction is the drainage port member. It protrudes horizontally from the inner peripheral surface of the cylindrical portion 34 of 18 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 tubular main body 50, the portion 50C on the upstream side in the drainage direction protruding inward of the cylindrical portion 34 and above the axial center of the tubular main body 50 (the portion indicated by the diagonal line) corresponds to the rib. ing. The protrusion length L of the portion 50C corresponding to the rib from the inner peripheral surface of the cylindrical portion 34 is not particularly specified, but it is preferable that the portion 50C protrudes from the inner peripheral surface of the cylindrical portion 34 by about 5 to 25 mm at the time of mounting. The portion 50C corresponding to the rib protrudes downstream from the mesh portion 52 in the drainage direction. As a result, when cleaning the mesh portion 52, the portion 50C corresponding to the rib does not interfere with the cleaning even if the hand is reached 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, the drainage of the water supply device 16 flows into the siphon drainage pipe 26 via the drainage port member 18, the pipe 20, the S-shaped trap 22, and the pipe 24. The drainage flows laterally in the horizontal pulling pipe 28, then flows down the vertical pipe 30, and the siphon force is generated by the potential energy of the siphon head Hs in the vertical pipe 30. This 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 passed more quickly than when the mesh portion 52 is not curved (flat). As a result, it is possible to prevent the drainage from overflowing from the drainage port member 18.

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 opens the front side of the drainage outlet 40A on the side surface of the cylindrical portion 34 from above. Since it is provided so as to cover it, even if a large amount of drainage W is flowed to the water peripheral device 16, the drainage W that flows down along the inner surface of the cylindrical portion 34 of the drainage port member 18 is the drainage portion 40. The drainage W flowing down can be dispersed by the rib 60 as shown by the arrow A in FIGS. 4 and 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 section 40, the cylindrical portion 34 with respect to the drainage W (direction of arrow B in FIG. 13) that is about to flow toward the drainage outlet 40A of the discharge section 40. The portion 50C corresponding to the rib of the present invention changes the direction of the flow of the drainage W flowing down so that the drainage W flowing down along the inner surface does not interfere. As a result, the drainage W at the bottom of the cylindrical portion 34 of the drainage port member 18 can be smoothly flowed into the discharge portion 40 and discharged to the outside of the drainage port 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, it is possible to prevent the drainage W from overflowing from the drainage port member 18 into the sink even when a large amount of drainage is poured into the water peripheral device 16 at one time, for example, when the drainage is accumulated and drained. 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 it is possible to suppress the rise in the water level of the drainage W flowing into the inside of the drainage port member 18, as shown by the arrow C in FIG. 13, the air in the pipe on the downstream side is taken to the upper side of the drainage port mesh member 48. The drainage port member 18 can be smoothly discharged inward through the drainage port member 18. As a result, 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 and protrudes convexly toward the inside of the drainage port member 18, and is in the vertical direction (direction orthogonal to the bending direction). It is straight and is integrally provided on the edge 50B on the upstream side of the tubular body 50 in the drainage direction. Therefore, when the drainage port member 18 is viewed from above, there is no shadow on the mesh portion 52, that is, there is no place where foreign matter is hidden when viewed from above, and the foreign matter adhering to the mesh portion 52 is removed from the drainage port mesh member. It can be easily cleaned from the upper side of the drainage port 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 very small part, and the angle formed by one side and the other side is set to an acute angle (120 degrees as an example), so that one side and the other side are formed. Compared to the case where the angle formed by the sides is an acute angle, foreign matter in the drainage is less likely to get caught in the corners. Further, by making the shape of the hole 54 hexagonal 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。 Since the drainage port mesh member 48 of the present embodiment is removable from the drainage port 40, the drainage port mesh member 48 can be removed for cleaning. The drainage port mesh member 48 may be fixed to the drainage port 40 with a claw, an adhesive or the like (not shown) so that it cannot be removed from the drainage port 40, or may be integrally provided with 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。 In the drainage port mesh member 48 of the present embodiment, the mesh portion 52 is curved in the horizontal direction in the attached state, but the mesh portion 52 can be attached to the drainage portion 40 so as to be 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, in the drainage port mesh member 48 of the present embodiment, the mesh portion 52 is curved in an arc shape having a radius of curvature R, but the mesh portion 52 has a plurality of arcs having different radii of curvature. It may be a formed curved shape, or it may be a shape in which a plurality of straight lines are connected to be approximated to 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, the hole is not formed on the side surface of the tubular main body 50, but as an example, the portion shown by the diagonal line rising to the left in FIG. 13 (below the central axis of the tubular main body 50). On the side, a hole similar to the hole 54 of the mesh portion 52 may be formed in the portion (portion) 50D protruding from the cylindrical portion 34 of the drainage port member 18. As a result, in the drainage port mesh member 48, the portion through which the drainage W passes can be increased, and drainage can be performed more quickly.

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 has a convex shape toward the upstream side in the drainage direction, but the mesh portion 52 has a concave shape toward the upstream side in the drainage direction. May be curved.
