Description

本発明は、洗い場床の排水カバーおよび排水構造に関する。 The present invention relates to a drainage cover and drainage structure for a washing area floor.

浴室の洗い場床等の排水口には、髪の毛やゴミなどで排水管が詰まることを防ぐためにヘアキャッチャーが配されている。ヘアキャッチャーの上方は排水カバーで覆われており、ヘアキャッチャーが露出しないように構成されている。 Hair catchers are placed at the drains on the floor of the bathroom washing area to prevent the drains from becoming clogged with hair and debris. The upper part of the hair catcher is covered with a drainage cover so that the hair catcher is not exposed.

例えば特許文献１には、洗い場床に設けられた凹所内にヘアキャッチャーを配し、ヘアキャッチャーを覆う排水カバーが設けられた排水構造が開示されている。凹所は、平面視形状が略長方形の枡状部であり、その底部には排水トラップ連結用の開口が設けられている。凹所の四隅には、上向き段部よりなる排水カバー載置部が設けられている。排水カバー載置部に四隅を載せるようにして、略長方形の板状体よりなる排水カバーが装着される。 For example, Patent Document 1 discloses a drainage structure in which a hair catcher is arranged in a recess provided in a washing area floor and a drainage cover is provided to cover the hair catcher. The recess is a square-shaped part having a substantially rectangular shape in plan view, and an opening for connecting a drain trap is provided at the bottom of the recess. At the four corners of the recess, drain cover mounting portions each having an upwardly facing stepped portion are provided. A drain cover made of a substantially rectangular plate is mounted so that its four corners are placed on the drain cover mounting portion.

特開２０１１－２２６１９７号公報Japanese Patent Application Publication No. 2011-226197

特許文献１に記載の排水構造は、排水カバーの四隅における側面が凹所の四隅における内側面に対向し、両面の間に狭所が生じて水が溜まり易くなる。このような狭所に髪の毛を含んだ水が流れ込むと、髪の毛が狭所で停滞して付着してしまう。排水カバー載置部と排水カバーとの接触部分における隙間にも、水が流れ込み、髪の毛が接触部分の周りに付着してしまう。 In the drainage structure described in Patent Document 1, the side surfaces at the four corners of the drainage cover face the inner surfaces at the four corners of the recess, and a narrow space is created between the two surfaces, making it easy for water to accumulate. When water containing hair flows into such a narrow space, the hair becomes stagnant and adheres to the narrow space. Water also flows into the gap at the contact area between the drain cover placement part and the drain cover, and hair adheres around the contact area.

本発明は、斯かる事情に鑑みてなされたものであり、その目的とするところは、脚部周りの通水性を高めて髪の毛の付着を抑制することができる排水カバーおよび排水構造を提供することにある。 The present invention has been made in view of the above circumstances, and its purpose is to provide a drainage cover and a drainage structure that can increase water permeability around the legs and suppress the attachment of hair. It is in.

（実施形態）
図１、図２を参照する。洗い場床８は、平面視長方形状をなし、浴槽側の側辺部８ａの中央に排水構造１が配置されている。洗い場床８は、側辺部８ａに対向する側辺部８ｂから側辺部８ａに向かうにつれて下降する勾配を有し、側辺部８ａに交差する側辺部８ｃから側辺部８ａの中央部へ向かうにつれて下降する勾配を有する。洗い場床８に降りかかった水は、側辺部８ａの中央に設けられた排水構造１へ向かって流れる。 (Embodiment)
Please refer to FIGS. 1 and 2. The washing area floor 8 has a rectangular shape in plan view, and the drainage structure 1 is arranged in the center of the side part 8a on the bathtub side. The washing area floor 8 has a slope that descends from the side part 8b opposite to the side part 8a toward the side part 8a, and from the side part 8c crossing the side part 8a to the center part of the side part 8a. It has a slope that decreases as it goes towards. The water falling on the washing area floor 8 flows toward the drainage structure 1 provided at the center of the side part 8a.

排水構造１は、凹所１０、排水カバー２０等を備え、凹所１０の底部には上下に貫通する排水口１１が設けられている。排水口１１の下方に排水部６が設けられている。排水口１１には筒状の接続フランジ６１が取り付けられており、接続フランジ６１にヘアキャッチャー５が取り付けられている。 The drainage structure 1 includes a recess 10, a drainage cover 20, etc., and a drainage port 11 penetrating vertically is provided at the bottom of the recess 10. A drain section 6 is provided below the drain port 11. A cylindrical connection flange 61 is attached to the drain port 11, and a hair catcher 5 is attached to the connection flange 61.

接続フランジ６１の下方にはトラップ部６２が設けられている。洗い場床８からの水は、トラップ部６２へ流入し、排出口６４から排出される。浴槽の排水口に接続される浴槽側接続部６３は、配管を介してトラップ部６２に接続されており、浴槽からの水もトラップ部６２へ流入し、排出口６４から排出される。 A trap portion 62 is provided below the connection flange 61. Water from the washing area floor 8 flows into the trap section 62 and is discharged from the outlet 64. A bathtub-side connection portion 63 connected to the drain port of the bathtub is connected to the trap portion 62 via piping, and water from the bathtub also flows into the trap portion 62 and is discharged from the discharge port 64.

図３を参照する。凹所１０は平面視で略長方形の枡状である。凹所１０は、底部に円形の排水口１１を有している。凹所１０の内側部であって、排水口１１の周りには、洗い場床８の床面よりも低い位置にある段部でなる載置部１２が形成されている。載置部１２には排水カバー２０が載せ置かれ、排水カバー２０によって排水口１１と載置部１２とが覆われる。 See FIG. 3. The recess 10 has a substantially rectangular square shape when viewed from above. The recess 10 has a circular drainage port 11 at the bottom. Inside the recess 10 and around the drain port 11, a mounting section 12 is formed which is a stepped section located at a lower position than the floor surface of the washing area floor 8. A drain cover 20 is placed on the mounting section 12, and the drain cover 20 covers the drain port 11 and the mounting section 12.

載置部１２は、平面視長方形状の凹所１０の内部であり、円形の排水口１１領域の外側であるので、少なくとも凹所１０内の四隅に形成される。平面視において、凹所１０の辺の長さよりも排水口１１の直径が小さい場合には、凹所１０の辺の部分にも載置部１２が形成できる。 The mounting portions 12 are located inside the recess 10 which is rectangular in plan view and outside the circular drainage port 11 area, and are therefore formed at least at the four corners of the recess 10 . In a plan view, if the diameter of the drain port 11 is smaller than the length of the side of the recess 10, the mounting portion 12 can also be formed on the side of the recess 10.

図４、図５を参照する。排水カバー２０は、矩形板状の蓋部２１、および脚部２２を有する。平面視において、蓋部２１の外形寸法は凹所１０よりも小さく、凹所１０内に蓋部２１が納まり、蓋部２１の上面を洗い場床８の床面と面一とすることができる。脚部２２は、柱状をなし蓋部２１の四隅に設けられている。 Refer to FIGS. 4 and 5. The drain cover 20 has a rectangular plate-shaped lid part 21 and leg parts 22. In a plan view, the outer dimensions of the lid part 21 are smaller than the recess 10, and the lid part 21 is accommodated in the recess 10, so that the upper surface of the lid part 21 can be flush with the floor surface of the washing area floor 8. The leg portions 22 have a columnar shape and are provided at the four corners of the lid portion 21.

脚部２２は、底面から見て外側に対して凸となる円弧状に形成されている。脚部２２の一端側２２ａは、蓋部２１の外周縁から内側に後退した位置にある。これに比べて、脚部２２の他端側２２ｂは、蓋部２１の外周縁に近接した位置にある。 The leg portion 22 is formed in an arcuate shape that is convex toward the outside when viewed from the bottom surface. One end side 22a of the leg portion 22 is located at a position retreating inward from the outer peripheral edge of the lid portion 21. In comparison, the other end side 22b of the leg portion 22 is located closer to the outer peripheral edge of the lid portion 21.

排水カバー２０を凹所１０内に載置したときに、脚部２２の一端側２２ａと凹所１０の内側面との間の隙間は、脚部２２の他端側２２ｂと凹所１０の内側面との間の隙間よりも広くなる。このことは、排水カバー２０の四隅において同等である。 When the drain cover 20 is placed in the recess 10, the gap between the one end 22a of the leg 22 and the inner surface of the recess 10 is the same as the gap between the other end 22b of the leg 22 and the inner surface of the recess 10. It will be wider than the gap between it and the sides. This also applies to the four corners of the drain cover 20.

図６を参照する。脚部２２の外側面２３は、脚部２２の高さ方向を含み外側面２３に交差する断面において外側に対して凹となる円弧状に形成されている。また脚部２２の外側面２３は、脚部２２の高さ方向における上端部２３ａおよび下端部２３ｃが、中途部２３ｂよりも外側に張り出すように形成されている。本発明における第１の部位は脚部２２の下端部２３ｃに相当し、第１の高さは脚部２２の下端に相当する。本発明における第２の部位は脚部２２の中途部２３ｂに相当し、第２の高さは脚部２２の中途部２３ｂの高さに相当する。第２の高さは例えば脚部２２の高さの半分の高さである。 See FIG. 6. The outer surface 23 of the leg portion 22 is formed into an arcuate shape that is concave toward the outside in a cross section that includes the height direction of the leg portion 22 and intersects the outer surface 23. Moreover, the outer surface 23 of the leg part 22 is formed so that the upper end part 23a and the lower end part 23c in the height direction of the leg part 22 protrude outward from the middle part 23b. The first portion in the present invention corresponds to the lower end 23c of the leg 22, and the first height corresponds to the lower end of the leg 22. The second portion in the present invention corresponds to the midway portion 23b of the leg portion 22, and the second height corresponds to the height of the midway portion 23b of the leg portion 22. The second height is, for example, half the height of the leg portion 22.

次に排水構造１の動作について説明する。図７および図８を参照する。図７は排水カバー２０を凹所１０に載置した状態の側面図に相当している。洗い場床８からの水は、図７に示す矢印Ｐのように、凹所１０の四隅において、排水カバー２０の蓋部２１の外周縁と凹所１０の内側面との間の隙間から流れ込み、脚部２２の外側面２３と凹所１０の内側面との間に流下する。 Next, the operation of the drainage structure 1 will be explained. See FIGS. 7 and 8. FIG. 7 corresponds to a side view of the drain cover 20 placed in the recess 10. The water from the washing area floor 8 flows into the four corners of the recess 10 from the gaps between the outer periphery of the lid 21 of the drain cover 20 and the inner surface of the recess 10, as indicated by the arrow P shown in FIG. It flows down between the outer surface 23 of the leg 22 and the inner surface of the recess 10.

脚部２２の外側面２３と凹所１０の内側面との間に流下した水は、図７に示す矢印Ｑのように、横方向へ流れの方向が変わり、脚部２２の外側面２３と凹所１０の内側面との間に形成される通流路３０を通流し、脚部２２の間から排水口１１へと流れる。 The water flowing down between the outer surface 23 of the leg 22 and the inner surface of the recess 10 changes its flow direction laterally, as shown by the arrow Q shown in FIG. It flows through the passageway 30 formed between the inner surface of the recess 10 and from between the legs 22 to the drain port 11 .

脚部２２の外側面２３は、下端部２３ｃが中途部２３ｂよりも外側に張り出すように形成されているため、通流路３０に流れ込んだ水が矢印Ｑのように脚部２２に沿って流れ易くなる。通流路３０内において、脚部２２に沿って通水性が高くなることで、水に含まれる髪の毛が脚部２２まわりに付着することを抑制することができる。 The outer surface 23 of the leg portion 22 is formed such that the lower end portion 23c protrudes outward from the midway portion 23b, so that water flowing into the flow path 30 flows along the leg portion 22 as indicated by the arrow Q. It becomes easier to flow. By increasing water permeability along the leg portions 22 in the flow path 30, hair contained in water can be prevented from adhering around the leg portions 22.

また脚部２２の外側面２３は、脚部２２の高さ方向を含み外側面に交差する断面において外側に対して凹となる円弧状に形成されており、脚部２２の該側面に形成される、中途部２３ｂを底とする断面円弧状の溝に沿って水がより流れ易くなる。 The outer surface 23 of the leg 22 is formed in an arcuate shape that is concave toward the outside in a cross section that includes the height direction of the leg 22 and intersects with the outer surface. Water flows more easily along the groove having an arcuate cross section with the midway portion 23b as the bottom.

図８に示す矢印Ｒのように、通流路３０に流れ込んだ水が凹所１０の内側面から脚部２２へ向かって流れた場合を考える。脚部２２は、その高さ方向に交差する断面において外側に対して凸となる円弧状に形成されているので、脚部２２に向かって流れてきた水の方向が横方向へ変化し易く、流れ込んだ水が通流路３０に滞留することを抑制することができる。 Consider a case where water that has flowed into the flow path 30 flows from the inner surface of the recess 10 toward the leg portion 22 as indicated by arrow R shown in FIG. 8 . Since the leg portions 22 are formed in an arcuate shape that is convex toward the outside in a cross section that intersects with the height direction, the direction of water flowing toward the leg portions 22 tends to change laterally. It is possible to prevent the water that has flowed in from staying in the flow path 30.

また図８に示すように、脚部２２の一端側２２ａと凹所１０の内側面との間の隙間は、脚部２２の他端側２２ｂと凹所１０の内側面との間の隙間よりも広くなっている。このため、通流路３０に流れ込んだ水が一端側２２ａの方へ流れ易くなっており、流速の低下を抑制することができる。 Further, as shown in FIG. 8, the gap between one end 22a of the leg 22 and the inner surface of the recess 10 is larger than the gap between the other end 22b of the leg 22 and the inner surface of the recess 10. It is also wider. Therefore, the water that has flowed into the flow path 30 easily flows toward the one end side 22a, and a decrease in the flow velocity can be suppressed.

（変形例）
図９（ａ）～図９（ｄ）を参照する。図９（ａ）に示す排水カバー２０では、脚部２２の外側面２３が、脚部２２の高さ方向を含み外側面に交差する断面において外側に対して凹状であり、外側から一定の深さに穿たれた形状となっている。この場合も断面が円弧状の場合と同様に外側面２３に沿って水が流れ易くなる。 (Modified example)
Refer to FIGS. 9(a) to 9(d). In the drain cover 20 shown in FIG. 9(a), the outer surface 23 of the leg 22 is concave toward the outside in a cross section that includes the height direction of the leg 22 and intersects with the outer surface, and has a certain depth from the outside. It has a perforated shape. In this case as well, water flows easily along the outer surface 23 as in the case where the cross section is arcuate.

図９（ｂ）に示す排水カバー２０では、脚部２２の高さ方向における上端部２３ａから下端部２３ｃにかけて徐々に外側へ張り出すように脚部２２の外側面２３が形成されている。この場合、上端部２３ａ寄りに溝が形成されることで、外側面２３に沿って水が流れ易くなる。 In the drain cover 20 shown in FIG. 9(b), the outer surface 23 of the leg 22 is formed so as to gradually project outward from the upper end 23a to the lower end 23c in the height direction of the leg 22. In this case, the grooves are formed closer to the upper end 23a, making it easier for water to flow along the outer surface 23.

図９（ｃ）に示す排水カバー２０では、蓋部２１の外周縁に対応する位置に、脚部２２の上端部２３ａが形成され、上端部２３ａから下端部２３ｃにかけて徐々に外側へ張り出すように脚部２２の外側面２３が形成されている。この場合、上端部２３ａ寄りに上方が開放された溝が形成されていることになり、外側面２３に沿って水が流れ易くなる。 In the drain cover 20 shown in FIG. 9(c), the upper end portion 23a of the leg portion 22 is formed at a position corresponding to the outer peripheral edge of the lid portion 21, and gradually extends outward from the upper end portion 23a to the lower end portion 23c. An outer surface 23 of the leg portion 22 is formed on the outer surface 23 of the leg portion 22 . In this case, a groove with an open top is formed near the upper end 23a, making it easier for water to flow along the outer surface 23.

図９（ｄ）に示す排水カバー２０では、脚部２２の高さ方向における下端部２３ｃが中途部２３ｂよりも内側に凹むように脚部２２の外側面２３が形成されている。この場合、脚部２２が接触する載置部１２とで下端部２３ｃ寄りに溝が形成されていることになり、外側面２３に沿って水が流れ易くなる。この場合、本発明における第１の部位は脚部２２の中途部２３ｂに相当し、第１の高さは脚部２２の中途部２３ｂの高さに相当する。本発明における第２の部位は脚部２２の下端部２３ｃに相当し、第２の高さは脚部２２の下端に相当する。第１の高さは例えば脚部２２の高さの半分の高さである。 In the drain cover 20 shown in FIG. 9(d), the outer surface 23 of the leg portion 22 is formed such that the lower end portion 23c of the leg portion 22 in the height direction is recessed inward than the midway portion 23b. In this case, a groove is formed near the lower end 23c between the mounting portion 12 that the leg portion 22 contacts, and water easily flows along the outer surface 23. In this case, the first portion in the present invention corresponds to the midway portion 23b of the leg portion 22, and the first height corresponds to the height of the midway portion 23b of the leg portion 22. The second portion in the present invention corresponds to the lower end 23c of the leg 22, and the second height corresponds to the lower end of the leg 22. The first height is, for example, half the height of the leg portion 22.

以上、本発明の実施の形態をもとに説明した。これらの実施の形態は例示であり、いろいろな変形および変更が本発明の特許請求範囲内で可能なこと、またそうした変形例および変更も本発明の特許請求の範囲にあることは当業者に理解されるところである。従って、本明細書での記述および図面は限定的ではなく一例として扱われるべきものである。 The above description has been based on the embodiments of the present invention.
