Description

本発明は、排水蓋に関する。   The present invention relates to a drain lid.

従来、排水口が異物によって詰まるのを防止するため、浴室等の床に形成された排水枡の開口面は排水蓋で覆われる。また、このような排水蓋では、裏面に複数の補強リブが設けられている（例えば、特許文献１）。 Conventionally, in order to prevent the drain outlet from being clogged with foreign substances, the opening surface of the drainage basin formed on the floor of a bathroom or the like is covered with a drainage lid. In such a drain lid, a plurality of reinforcing ribs are provided on the back surface (for example, Patent Document 1).

しかしながら、複数の補強リブによって囲まれた空間に空気が滞留すると、排水枡へ排水が流されたとき、滞留した空気が排出されずに排水蓋が浮き上がる。また、補強リブの周辺は水切れが悪く、排水蓋が汚れやすい。   However, if the air stays in the space surrounded by the plurality of reinforcing ribs, the drainage lid rises without the staying air being discharged when the drainage is poured into the drainage basin. In addition, water drainage is poor around the reinforcing ribs, and the drainage lid is easily soiled.

特開２０００−８４３５JP2000-8435

本発明は上記事項を考慮し、排水蓋の水切れを向上させることを目的とする。   The present invention is intended to improve the drainage of the drainage lid in consideration of the above matters.

請求項１に記載の排水蓋は、床に形成された排水枡へ裏面に設けた脚部が載置されて前記排水枡の開口面を覆うと共に、外周部から排水枡内へ排水を流入させる導水部が形成された蓋体と、前記蓋体の裏面に形成された傾斜面と、を有し、前記蓋体は矩形状であり、隣り合う前記傾斜面が稜線を形成する。 The drain lid according to claim 1 is configured such that legs provided on the back surface are placed on a drainage basin formed on the floor to cover the opening surface of the drainage basin and drainage is allowed to flow into the drainage basin from the outer periphery. The lid body has a water guide portion and an inclined surface formed on the back surface of the lid body, the lid body is rectangular, and the adjacent inclined surfaces form ridge lines .

請求項１に記載の排水蓋では、蓋体の裏面に傾斜面が形成されているので、排水が蓋体の外周部から排水枡内へ流入したとき、排水蓋の裏面に付着した排水は、斜面部に沿って排水蓋の裏面の一箇所に集められるので、排水蓋の水切れを向上させ、排水蓋を清潔に保つことができる。   In the drain lid according to claim 1, since the inclined surface is formed on the back surface of the lid body, when the drainage flows into the drainage basin from the outer peripheral portion of the lid body, the drainage adhered to the back surface of the drain lid is Since it collects in one place of the back of a drain lid along a slope part, drainage of a drain lid can be improved and a drain lid can be kept clean.

また、排水枡内の空気は、蓋体の裏面に滞留することなく傾斜面に沿って外へ排出される。これにより、排水蓋が浮き上がるのを抑制できる。   Further, the air in the drainage basin is discharged outside along the inclined surface without staying on the back surface of the lid. Thereby, it can control that a drain lid lifts up.

さらに、請求項１に記載の排水蓋では、傾斜面に付着した排水が稜線に集まり、稜線を伝って蓋体の裏面の一箇所に集められるので、排水蓋の水切れが向上する。
請求項２に記載の排水蓋は、前記稜線は、前記蓋体の対角線上にある。
請求項２に記載の排水蓋では、対角線上に稜線が形成されているので、排水蓋の剛性が向上する。 Furthermore, in the drain lid according to claim 1 , drainage adhering to the inclined surface gathers on the ridgeline and is collected at one place on the back surface of the lid body along the ridgeline, so that drainage of the drainage lid is improved.
In the drain lid according to claim 2, the ridgeline is on a diagonal line of the lid.
In the drain lid according to claim 2, since the ridge line is formed on the diagonal line, the rigidity of the drain lid is improved.

請求項３に記載の排水蓋は、床に形成された排水枡へ裏面に設けた脚部が載置されて前記排水枡の開口面を覆うと共に、外周部から排水枡内へ排水を流入させる導水部が形成された蓋体と、前記蓋体の裏面に形成された傾斜面と、を有し、前記傾斜面は、前記蓋体の中心部に向かって傾斜する下り傾斜面である。 The drainage lid according to claim 3 is configured such that a leg provided on the back surface is placed on a drainage basin formed on the floor to cover the opening surface of the drainage basin and drainage is allowed to flow into the drainage basin from the outer periphery. It has a lid body in which a water guide portion is formed and an inclined surface formed on the back surface of the lid body, and the inclined surface is a downward inclined surface that inclines toward the center of the lid body.

請求項３に記載の排水蓋では、蓋体の裏面に形成された傾斜面が蓋体の中心部に向かって傾斜しているので、排水蓋の裏面に付着した排水を効率よく集めることができる。   In the drain lid according to claim 3, since the inclined surface formed on the back surface of the lid body is inclined toward the center of the lid body, the waste water adhering to the back surface of the drain lid can be efficiently collected. .

請求項４に記載の排水蓋は、床に形成された排水枡へ裏面に設けた脚部が載置されて前記排水枡の開口面を覆うと共に、外周部から排水枡内へ排水を流入させる導水部が形成された蓋体と、前記蓋体の裏面に形成された傾斜面と、を有し、前記蓋体の裏面に形成され、中心部から外周部へ向かって下り傾斜するリブと、前記リブの端部に設けられ、前記排水枡に載置される補助脚部と、をさらに有する。 The drainage lid according to claim 4 is configured such that a leg provided on the back surface is placed on a drainage basin formed on the floor to cover the opening surface of the drainage basin and drainage is allowed to flow into the drainage basin from the outer periphery. A rib having a water guide portion formed thereon, an inclined surface formed on the back surface of the lid body, formed on the back surface of the lid body, and a rib inclined downward from the central portion toward the outer periphery; And an auxiliary leg provided on the end of the rib and placed on the drainage basin.

請求項４に記載の排水蓋では、リブが蓋本体の中心部から外周部へ向かって下り傾斜しているので、裏面の稜線を伝って排水蓋の裏面の中心部へ集められた排水は、リブに沿って蓋体の外周部へ流れ、さらにリブの端部に設けられた補助脚部を伝って排水枡へ流れる。これにより、落水させるより排水蓋の水切れが向上し、排水蓋を清潔に保つことができる。 In the drainage lid according to claim 4 , since the rib is inclined downward from the center part of the lid body toward the outer peripheral part, the drainage collected to the center part of the back surface of the drainage lid through the ridge line on the back surface, It flows along the rib to the outer periphery of the lid, and further flows through the auxiliary leg provided at the end of the rib to the drain. Thereby, the drainage of the drain lid is improved as compared with dropping the water, and the drain lid can be kept clean.

請求項５に記載の排水蓋は、前記リブは矩形状の前記蓋体の各辺の中心部へ延びる十字形状である。 In the drainage lid according to claim 5 , the rib has a cross shape extending to the center of each side of the rectangular lid.

請求項５に記載の排水蓋では、リブは十字形状であるため、蓋体の裏面の空気がリブに遮られることなく、排水枡の外へ排出される。また、リブは蓋体の各辺の中心部へ延びているので、排水蓋の剛性が向上する。 In the drainage lid according to the fifth aspect , since the rib has a cross shape, air on the back surface of the lid body is discharged outside the drainage basin without being blocked by the rib. Moreover, since the rib extends to the center of each side of the lid, the rigidity of the drain lid is improved.

請求項６に記載の排水蓋は、前記リブの外周面は弧状となっている。 In the drain lid according to claim 6 , the outer peripheral surface of the rib is arcuate.

請求項６に記載の排水蓋では、リブの外周面は弧状となっており、リブに付着した排水が留まりにくく、また、清掃しやすい。 In the drainage lid according to the sixth aspect, the outer peripheral surface of the rib has an arc shape, so that the drainage attached to the rib hardly stays and is easy to clean.

請求項７に記載の排水蓋は、前記蓋体の上面には、中心部から外周部に向かって下り傾斜面が形成されている。 In the drain lid according to claim 7 , a downwardly inclined surface is formed on the upper surface of the lid body from the central portion toward the outer peripheral portion.

請求項７に記載の排水蓋では、排水蓋の上面に付着した排水は、下り傾斜面を流れて蓋体の裏面に回り込み、排水蓋の裏面の中心部に集められるので、排水蓋の上面の水切れが向上する。 In the drain lid according to claim 7 , the drainage adhered to the upper surface of the drain lid flows down the inclined surface, wraps around the back surface of the lid body, and is collected at the center of the back surface of the drain lid. Water drainage is improved.

本発明は、上記の構成としたので、排水蓋の水切れが向上する。   Since this invention was set as said structure, the drainage of a drain cover improves.

本発明の第１実施形態に係る排水蓋１０について説明する。図１に示すように、浴室１００は、洗い場１０２と浴槽１０４で構成されており、洗い場１０２の床面は床１０２Ａで形成されている。床１０２Ａには、浴槽１０４と洗い場１０２との境界近傍に凹状の排水枡１０６が形成されている。   The drain lid 10 according to the first embodiment of the present invention will be described. As shown in FIG. 1, the bathroom 100 includes a washing place 102 and a bathtub 104, and the floor surface of the washing place 102 is formed of a floor 102A. A concave drainage basin 106 is formed in the vicinity of the boundary between the bathtub 104 and the washing place 102 on the floor 102A.

排水枡１０６の底部の中心部には、排水口１０８が形成されており、床１０２Ａから排水枡１０６内に流れ込んだ排水は、排水口１０８から図示しない排水管を通って下水へ流される。また、排水口１０８に形成された段差部１０８Ａには、毛髪等を捕集するヘアキャッチャー１１０が支持されている（図２参照）。   A drainage port 108 is formed at the center of the bottom of the drainage basin 106, and the drainage that has flowed into the drainage basin 106 from the floor 102A flows into the sewage through a drainage pipe (not shown). In addition, a hair catcher 110 that collects hair and the like is supported on the step portion 108A formed in the drain port 108 (see FIG. 2).

排水枡１０６の底部には、排水枡１０６の開口面を覆うように排水蓋１０が載置される。このとき、排水蓋１０の蓋体１４の裏面に形成された複数の脚部１２及び補助脚部２２が排水枡１０６の底部に載置される。   The drainage lid 10 is placed on the bottom of the drainage basin 106 so as to cover the opening surface of the drainage basin 106. At this time, the plurality of leg portions 12 and auxiliary leg portions 22 formed on the back surface of the lid body 14 of the drainage lid 10 are placed on the bottom of the drainage trough 106.

また、排水枡１０６の浴槽１０４側の側壁の上部には、床１０２Ａの上面から略半円柱状に凹んだ指掛け部１１２が形成されており、指掛け部１１２に指を掛けて排水枡１０６の底部に載置された排水蓋１０が取外される。   Further, a finger hook portion 112 that is recessed in a substantially semi-cylindrical shape from the upper surface of the floor 102A is formed on the upper portion of the side wall of the drain rod 106 on the bathtub 104 side. The drainage lid 10 placed on is removed.

図２に示すように、排水枡１０６の底部は排水口１０８に向かって緩やかに下り傾斜になっている。排水口１０８の周辺には段差部１０８Ａが形成されている。段差部１０８Ａには、ヘアキャッチャー１１０の外周部に形成されたフランジ部１１０Ａが載せられ、ヘアキャッチャー１１０の上面と排水口１０８の開口縁部が同一高さとなっている。また、ヘアキャッチャー１１０には排水を通水させる多数の通水孔１１６が形成されている。   As shown in FIG. 2, the bottom of the drainage basin 106 is gently inclined downward toward the drainage port 108. A step 108 </ b> A is formed around the drain port 108. A flange portion 110A formed on the outer peripheral portion of the hair catcher 110 is placed on the step portion 108A, and the upper surface of the hair catcher 110 and the opening edge portion of the drain port 108 are at the same height. The hair catcher 110 is formed with a number of water holes 116 through which drainage flows.

さらに、蓋体１４の上面の外周部と床１０２Ａとは同じ高さとなっており、蓋体１４の上面の中心部は、床１０２Ａより高く形成され、中心部から外周部へ向かって矢印方向に下り傾斜面が形成されている。また、蓋体１４の外形は、蓋体１４と排水枡１０６の開口縁部１０６Ａとの間に隙間が生じる大きさとされている。   Further, the outer peripheral portion of the upper surface of the lid body 14 and the floor 102A have the same height, and the central portion of the upper surface of the lid body 14 is formed higher than the floor 102A, and extends in the direction of the arrow from the central portion toward the outer peripheral portion. A downward inclined surface is formed. In addition, the outer shape of the lid body 14 is set to a size that creates a gap between the lid body 14 and the opening edge portion 106 </ b> A of the drainage basin 106.

さらに蓋体１４をさらに詳しく説明すると、図３に示すように、蓋体１４は長方形の平板部材であり、ＡＢＳ樹脂等の合成樹脂で形成されている。これにより、蓋体１４の表面は、撥水特性を備え、付着した排水が水滴となりやすくなっている。蓋体１４の上面の中心部には、蓋体１４の４つの角部から中心部に向かう４本の溝１８Ａによって菱形の領域１４Ａが形成されており、領域１４Ａの蓋体１４の短辺の中心線ＣＬ上には、稜線１５が形成されている。領域１４Ａは、稜線１５を頂部として下り傾斜面となっている。   Further, the lid body 14 will be described in more detail. As shown in FIG. 3, the lid body 14 is a rectangular flat plate member and is made of a synthetic resin such as an ABS resin. Thereby, the surface of the lid body 14 has a water-repellent property, and the attached waste water tends to be water droplets. A rhombus region 14A is formed at the center of the upper surface of the lid 14 by four grooves 18A from the four corners of the lid 14 toward the center, and the short side of the lid 14 in the region 14A. A ridge line 15 is formed on the center line CL. The region 14A is a downwardly inclined surface with the ridge line 15 as the top.

また、蓋体１４の上面の短辺側には、上述した溝１８Ａと蓋体１４の短辺によって三角形の領域１４Ｂが形成されている。さらに、蓋体１４の上面の長辺側には、上述した溝１８Ａ及び、長辺の中心部から領域１４Ａに向かって形成された溝１８Ｂによって、台形状の領域１４Ｃがそれぞれの長辺側に２つずつ形成されている。領域１４Ｂ及び１４Ｃは、蓋体１４の外周部へ向かって下り傾斜面となっている。   Further, on the short side of the upper surface of the lid body 14, a triangular region 14 </ b> B is formed by the above-described groove 18 </ b> A and the short side of the lid body 14. Further, on the long side of the upper surface of the lid body 14, the trapezoidal region 14 </ b> C is formed on each long side by the groove 18 </ b> A and the groove 18 </ b> B formed from the center of the long side toward the region 14 </ b> A. Two are formed. The regions 14 </ b> B and 14 </ b> C are inclined downward toward the outer periphery of the lid body 14.

図４に示すように、蓋体１４の裏面１４Ｄは、蓋体１４の外周部から中心部に向かって下り傾斜している（図６参照）。また、対角線上には稜線２６が形成されている。さらに、この稜線２６を境にしてそれぞれの傾斜面が蓋体１４の外周部に向かって下り傾斜している。   As shown in FIG. 4, the back surface 14 </ b> D of the lid body 14 is inclined downward from the outer peripheral portion of the lid body 14 toward the center portion (see FIG. 6). A ridge line 26 is formed on the diagonal line. Further, each inclined surface is inclined downward toward the outer peripheral portion of the lid body 14 with the ridge line 26 as a boundary.

蓋体１４の裏面１４Ｄの角部には、円柱状の脚部１２が下方へ突出して形成されている。また、それぞれの脚部１２の外周部には、蓋体１４へ連結される脚部補強リブ１２Ａが形成されている。   At the corner of the back surface 14D of the lid body 14, columnar leg portions 12 are formed protruding downward. Further, leg reinforcing ribs 12 </ b> A connected to the lid body 14 are formed on the outer peripheral portions of the respective leg portions 12.

さらに、蓋体１４の裏面１４Ｄには、蓋体１４の中心部から蓋体１４の各辺の中心部へ延びた十字形状の蓋体補強リブ２４が形成されている。蓋体補強リブ２４は、蓋体１４の中心部から各辺の中心部に向かって下り傾斜しており、蓋体補強リブ２４の外周面は弧状となっており、清掃しやすくなっている。また、蓋体補強リブ２４の外周面が弧状となっているので、蓋体補強リブ２４に付着した排水は、蓋体補強リブ２４の最下点へ集まり、水滴になりやすい。このため、角を面取りしただけのリブよりも排水が滞留しにくい。   Further, a cross-shaped lid reinforcing rib 24 extending from the center of the lid 14 to the center of each side of the lid 14 is formed on the back surface 14D of the lid 14. The lid reinforcing rib 24 is inclined downward from the central portion of the lid 14 toward the central portion of each side, and the outer peripheral surface of the lid reinforcing rib 24 is arcuate and is easy to clean. Further, since the outer peripheral surface of the lid reinforcing rib 24 is arcuate, the waste water adhering to the lid reinforcing rib 24 gathers at the lowest point of the lid reinforcing rib 24 and tends to be water droplets. For this reason, drainage is less likely to stay than ribs whose corners are chamfered.

また、蓋体補強リブ２４の端部には、円柱状の補助脚部２２が形成されている。補助脚部２２は、脚部１２と同じ高さであり、補助脚部２２の外周部には、蓋体１４へ連結される補助脚部補強リブ２２Ａが形成されている。   A cylindrical auxiliary leg portion 22 is formed at the end of the lid reinforcing rib 24. The auxiliary leg portion 22 has the same height as the leg portion 12, and an auxiliary leg portion reinforcing rib 22 </ b> A connected to the lid body 14 is formed on the outer peripheral portion of the auxiliary leg portion 22.

図３及び図４示すように、蓋体１４の外周部は角が取られて丸みを帯びており、４辺には蓋体１４の外周部を内側へ凹ませた導水部としての凹部２０が形成されている。   As shown in FIGS. 3 and 4, the outer peripheral portion of the lid body 14 is rounded and rounded, and a concave portion 20 as a water guiding portion is formed on the four sides by denting the outer peripheral portion of the lid body 14 inward. Is formed.

凹部２０は、蓋体１４の中心線ＣＬより右側にのみ形成されており、各辺の半分よりやや短い長さとされている。また、凹部２０の凹み量は、図５に示すように、排水蓋１０を排水枡１０６へ載置した際に、蓋体１４と排水枡１０６の開口縁部１０６Ａとの間に指が入らない程度に設定されている。   The recess 20 is formed only on the right side of the center line CL of the lid body 14 and has a length slightly shorter than half of each side. Further, as shown in FIG. 5, when the drain lid 10 is placed on the drainage basin 106, the amount of dent of the recess 20 does not allow a finger to enter between the lid 14 and the opening edge 106 </ b> A of the drainage basin 106. Is set to about.

なお、凹部２０は、蓋体１４の中心線ＣＬより右側に形成されていれば、中心線ＣＬから辺の端部まで連続して凹んでいなくてもよく、断続的に複数の凹部２０が形成されていてもよい。また、中心線ＣＬを越えて凹部２０を形成しても、凹部２０へ流入した排水の主流の中心が排水枡１０６の中心部より右側を流れれば旋回流が発生する。   In addition, as long as the recessed part 20 is formed in the right side from the center line CL of the cover body 14, it does not need to be continuously recessed from the center line CL to the edge part of a side, and the some recessed part 20 is intermittently formed. It may be formed. Further, even if the recess 20 is formed beyond the center line CL, a swirling flow is generated if the center of the main flow of drainage flowing into the recess 20 flows to the right of the center of the drainage basin 106.

また、本実施形態では、蓋体１４は矩形状であったが、他の形状でもよい。例えば、蓋体１４が三角形の場合、蓋体１４の各辺の中心部より右側を内側に凹ませて凹部２０を形成し、凹部２０へ流入した排水の主流の中心が排水枡１０６の中心部より右側を流れるようにすることで、旋回流が発生する。   In the present embodiment, the lid body 14 has a rectangular shape, but may have other shapes. For example, when the lid body 14 is a triangle, the concave portion 20 is formed by indenting the right side from the central portion of each side of the lid body 14, and the center of the main flow of drainage flowing into the concave portion 20 is the central portion of the drainage tub 106. A swirling flow is generated by making it flow on the right side.

次に、本実施形態に係る排水蓋１０の作用について説明する。   Next, the operation of the drain lid 10 according to the present embodiment will be described.

図５に示すように、蓋体１４の４辺を凹ませて形成された凹部２０と排水枡１０６の開口縁部１０６Ａとの間に隙間２８が形成されている。また、凹部２０を除いた蓋体１４の外形は、蓋体１４の外周部と排水枡１０６の開口縁部１０６Ａとの間に補助導水口としての隙間３０が生じる大きさに形成されている。なお、排水が隙間２８から流入する流入面積は、隙間３０から流入する流入面積よりも大きくなるように凹部２０が形成されている。   As shown in FIG. 5, a gap 28 is formed between the recess 20 formed by recessing the four sides of the lid body 14 and the opening edge 106 </ b> A of the drainage basin 106. Further, the outer shape of the lid body 14 excluding the concave portion 20 is formed in such a size that a gap 30 as an auxiliary water inlet is formed between the outer peripheral portion of the lid body 14 and the opening edge portion 106 </ b> A of the drainage basin 106. Note that the recess 20 is formed so that the inflow area where the wastewater flows from the gap 28 is larger than the inflow area where the drainage flows from the gap 30.

ここで、浴槽１０４（図１参照）、又は図示しないシャワーから洗い場１０２へ排水が流されると、排水は床１０２Ａを流れて排水枡１０６の開口縁部１０６Ａへ到達し、隙間２８及び隙間３０から排水枡１０６内に流入する。   Here, when drainage flows from the bathtub 104 (see FIG. 1) or a shower (not shown) to the washing place 102, the drainage flows through the floor 102A and reaches the opening edge 106A of the drainage basin 106, and from the gap 28 and the gap 30. It flows into the drain 106.

このとき、排水枡１０６内の空気は、排水が排水枡１０６内へ流入するのと同時に、排水蓋１０の裏面１４Ｄに沿って隙間２８及び隙間３０から排水枡１０６の外へ図４の矢印の方向へ排出される。ここで、蓋体補強リブ２４は十字形状に形成されているので、空気が蓋体補強リブ２４に遮られて蓋体１４の裏面１４Ｄに滞留することがない。このため、排水の流入によって排水蓋１０が浮き上がることもない。   At this time, the air in the drainage basin 106 flows out of the drainage basin 106 from the gap 28 and the gap 30 along the back surface 14D of the drainage lid 10 at the same time as the drainage flows into the drainage basin 106. Discharged in the direction. Here, since the lid reinforcing rib 24 is formed in a cross shape, air is not blocked by the lid reinforcing rib 24 and stays on the back surface 14D of the lid 14. For this reason, the drain lid 10 is not lifted by the inflow of drainage.

図５に示すように、隙間２８から排水枡１０６内に流入した排水の主流の中心は、蓋体１４の中心線に対して右側に導水され、矢印Ａの方向に流れる。また、排水枡１０６の底部は傾斜面となっているので、排水は排水枡１０６の中心部の周りに左旋回する。   As shown in FIG. 5, the center of the main flow of the drainage flowing into the drainage basin 106 from the gap 28 is guided to the right side with respect to the center line of the lid body 14 and flows in the direction of arrow A. Further, since the bottom of the drainage basin 106 is an inclined surface, the drainage turns left around the central part of the basin 106.

同様にして４辺の隙間２８から排水枡１０６へ流入した排水の主流の中心が矢印Ａの方向へ流れることで、排水枡１０６の中心部の周りに左旋回する旋回流Ｃが発生する。旋回流Ｃは、ヘアキャッチャー１１０上を左旋回しながら通水孔１１６を通って排水口１０８へ排水される。   Similarly, when the center of the main flow of the drainage flowing into the drainage basin 106 from the gap 28 on the four sides flows in the direction of arrow A, a swirl flow C that turns left around the central portion of the drainage basin 106 is generated. The swirl flow C is drained to the drain outlet 108 through the water passage hole 116 while swiveling left on the hair catcher 110.

また、隙間３０から排水枡１０６内に導水された排水は、矢印Ｂの方向に流れるが、隙間２８から流入した排水より排水量が少ないため、矢印Ａの方向に流れる主流に合流して旋回流Ｃとなる。ここで、排水に混じっている毛髪等は、旋回流Ｃによって排水枡１０６の中心部の周りに左旋回しながらヘアキャッチャー１１０上にまとまって捕集される。   In addition, the wastewater introduced from the gap 30 into the drainage basin 106 flows in the direction of arrow B, but since the amount of drainage is less than the wastewater that flows in from the gap 28, it merges with the main stream flowing in the direction of arrow A and swirls C It becomes. Here, the hair and the like mixed in the wastewater are collected together on the hair catcher 110 while turning leftward around the central portion of the drainage basin 106 by the swirling flow C.

次に、多量の排水が排水枡１０６へ流入したとき、蓋体１４の裏面１４Ｄ及び蓋体１４の上面には、排水の一部が残水として付着する。この残水のうち、蓋体１４の上面に付着した残水は、領域１４Ａ、１４Ｂ又は１４Ｃの下り傾斜面を伝って、或いは溝１８Ａ、１８Ｂを流れて蓋体１４の外周部へ到達する（図３参照）。   Next, when a large amount of drainage flows into the drainage basin 106, part of the drainage adheres to the back surface 14D of the lid 14 and the top surface of the lid 14 as residual water. Of this residual water, the residual water adhering to the upper surface of the lid body 14 reaches the outer peripheral portion of the lid body 14 along the downward sloping surface of the region 14A, 14B or 14C or through the grooves 18A and 18B ( (See FIG. 3).

蓋体１４の外周部へ到達した残水の一部は、図６に示すように、表面張力によって蓋体１４の裏面１４Ｄへ回り込む。また、一部の残水は、蓋体１４の外周部で水滴となって排水枡１０６の底部へ滴下し、ヘアキャッチャー１１０の通水孔１１６から排水される。   As shown in FIG. 6, a part of the remaining water that has reached the outer peripheral portion of the lid body 14 wraps around the back surface 14 </ b> D of the lid body 14 due to surface tension. A part of the remaining water is dropped on the bottom of the drainage basin 106 as water droplets on the outer periphery of the lid body 14 and drained from the water passage hole 116 of the hair catcher 110.

蓋体１４の上面から裏面１４Ｄへ回り込んだ残水は、排水が排水枡１０６へ流入したときに蓋体１４の裏面１４Ｄに付着した残水と共に、表面張力によって蓋体１４の裏面１４Ｄの傾斜面を流れて稜線２６へ集められ、稜線２６を矢印Ｄの方向に伝って蓋体補強リブ２４へ到達する。ここで、蓋体１４の裏面１４Ｄと蓋体補強リブ２４との接合部は滑らかに湾曲しているので、残水は蓋体補強リブ２４の外周面を伝って蓋体補強リブ２４の中心部２４Ａに集められる。   The residual water that has flowed from the upper surface of the lid body 14 to the rear surface 14D is inclined by the surface tension along with the residual water adhering to the rear surface 14D of the lid body 14 when the drainage flows into the drainage basin 106. It flows through the surface and is collected to the ridge line 26, and reaches the lid reinforcing rib 24 along the ridge line 26 in the direction of arrow D. Here, since the joint portion between the back surface 14D of the lid body 14 and the lid body reinforcing rib 24 is smoothly curved, the remaining water travels along the outer peripheral surface of the lid body reinforcing rib 24 and the center portion of the lid body reinforcing rib 24 Collected at 24A.

図７に示すように、蓋体補強リブ２４の中心部へ集められた残水は、蓋体補強リブ２４を伝って蓋体の各辺の中心部へ向かって流れ、補助脚部２２へ到達する。その後、補助脚部２２を伝って排水枡１０６の底部へと流れ、ヘアキャッチャー１１０の通水孔１１６から排水される。   As shown in FIG. 7, the remaining water collected at the center of the lid reinforcing rib 24 flows along the lid reinforcing rib 24 toward the center of each side of the lid and reaches the auxiliary leg 22. To do. Thereafter, it flows along the auxiliary leg 22 to the bottom of the drainage basin 106 and is drained from the water passage 116 of the hair catcher 110.

なお、本実施形態では、蓋体補強リブ２４は十字形状であったが、蓋体１４が撓みにくく、空気が滞留しない形状であれば、特に制限しない。例えば、蓋体１４の中心部から各辺の中心部及び四隅へ８方向に延びていてもよい。この場合、蓋体１４の対角線上に蓋体補強リブ２４を形成するので、稜線２６が形成できなくなる。このため、裏面１４Ｄの傾斜角度を調整し、裏面１４Ｄに付着した排水が確実に中心部へ流れるようにする。   In the present embodiment, the lid reinforcing rib 24 has a cross shape, but is not particularly limited as long as the lid 14 is not easily bent and does not retain air. For example, you may extend in eight directions from the center part of the cover body 14 to the center part and four corners of each side. In this case, since the lid reinforcing rib 24 is formed on the diagonal line of the lid 14, the ridge line 26 cannot be formed. For this reason, the inclination | tilt angle of back surface 14D is adjusted, and the waste_water | drain which adhered to back surface 14D flows reliably to a center part.

また、本実施形態では、蓋体１４の裏面１４Ｄの角部に４つの脚部１２が形成されていたが、補助脚部２２だけで耐荷重性が問題なければ脚部１２は形成されていなくてもよい。この場合、排水枡１０６の底部と接しているのは補助脚部２２だけなので、排水枡１０６へ流入する排水の流れを阻害しにくくなる。 Further, in the present embodiment, the four leg portions 12 are formed at the corners of the back surface 14D of the lid body 14, but the leg portions 12 are not formed if there is no problem with the load resistance only with the auxiliary leg portions 22. May be. In this case, since only the auxiliary leg portion 22 is in contact with the bottom of the drainage basin 106, it is difficult to hinder the flow of drainage flowing into the drainage basin 106.

以上、本発明の実施形態について説明したが、本発明はこうした実施形態に限定されるものでなく、本発明の要旨を逸脱しない範囲において、種々なる態様で実施し得ることは勿論である。例えば、蓋体補強リブ２４の中心部２４Ａをヘアキャッチャー１１０の上面近傍まで突出させて、蓋体補強リブ２４から直接ヘアキャッチャー１１０へ残水を流してもよい。   As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment, Of course, in the range which does not deviate from the summary of this invention, it can implement in a various aspect. For example, the central portion 24 </ b> A of the lid reinforcing rib 24 may be protruded to the vicinity of the upper surface of the hair catcher 110, and the remaining water may be directly flowed from the lid reinforcing rib 24 to the hair catcher 110.
