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、脚部周りにおける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 an object thereof is to provide a drainage cover and a drainage structure that can suppress the adhesion of hair around the legs.

本発明のある態様の排水カバーは、排水口を底部に有して洗い場床に形成された凹所を覆う蓋部と、前記凹所の内側部において前記洗い場床の床面から下がった段部でなる載置部に接触して前記蓋部を支持し、前記凹所の内側面に沿って配置されており、一端部における前記内側面との距離が他端部における前記内側面との距離よりも大きい脚部と、を備える。 A drainage cover according to an aspect of the present invention includes a lid portion that has a drain port at the bottom and covers a recess formed in a washing area floor, and a step portion that is lowered from the floor surface of the washing area floor at an inner side of the recess. The lid part is supported by contacting a mounting part made of the recess, and is arranged along the inner surface of the recess, and the distance from the inner surface at one end is the distance from the inner surface at the other end. It has legs larger than the.

(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の外側には、洗い場床8の床面から一段下がった段部でなる載置部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. On the inside of the recess 10 and on the outside of the drain port 11, a mounting part 12 is formed which is a stepped part that is one step lower than the floor surface of the washing area floor 8. A drainage cover 20 is placed on the placing portion 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、平面視において、排水口11の中央部、即ち、蓋部21の中央部から見て周方向に離れて複数設けられている。脚部22は、平面視において、排水口11の中央部、即ち、蓋部21の中央部から外側へ向かう方向に交差する方向に延びるように設けられている。外側へ向かう方向に交差する方向に延びるように設けられている。図4および図5に示す脚部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の一端部22aは、蓋部21の外側面から内側に後退した位置にある。これに比べて、脚部22の他端部22bは、蓋部21の外側面に近接した位置にある。 A plurality of leg portions 22 are provided apart from each other in the circumferential direction when viewed from the center of the drain port 11, that is, the center of the lid portion 21 in plan view. The leg portion 22 is provided so as to extend in a direction intersecting an outward direction from the central portion of the drain port 11, that is, the central portion of the lid portion 21, in a plan view. It is provided so as to extend in a direction intersecting the outward direction. The leg portion 22 shown in FIGS. 4 and 5 is formed in an arcuate shape that is convex toward the outside when viewed from the bottom. One end 22a of the leg 22 is in a position retracted inward from the outer surface of the lid 21. In comparison, the other end 22b of the leg 22 is located closer to the outer surface of the lid 21.

排水カバー20を凹所10内に載置したときに、脚部22の一端部22aと凹所10の内側面との間の隙間は、脚部22の他端部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 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は、全体として、蓋部21の外側面210の内側、即ち、蓋部21の平面視における中央側(「蓋部21の内側」とも表記する。)に形成されている。凹所10の内側面に臨む脚部22の外側面23について見る。脚部22の一端部22aにおいて、凹所10の内側面10aに臨む一端側外側面23aは、蓋部21の外側面21aおよび凹所10の内側面10aから蓋部21の内側へ離れて設けられている。 See FIG. 6. The leg portion 22 is formed as a whole on the inside of the outer surface 210 of the lid portion 21, that is, on the center side of the lid portion 21 in a plan view (also referred to as “inside of the lid portion 21”). Let us look at the outer surface 23 of the leg 22 facing the inner surface of the recess 10. At one end 22a of the leg portion 22, an outer surface 23a facing the inner surface 10a of the recess 10 is spaced away from the outer surface 21a of the lid 21 and the inner surface 10a of the recess 10 toward the inside of the lid 21. It is being

一方、脚部22の他端部22bにおいて、凹所10の内側面10bに臨む他端側外側面23bは、蓋部21の外側面21bとほぼ面一であり、凹所10の内側面10bと蓋部21の外側面21bとの隙間分だけ蓋部21の内側へ離れて設けられている。尚、蓋部21の外側面21aおよび外側面21bは、隅部で交わる2つの外側面である。凹所10の内側面10aおよび内側面10bは、隅部で交わる2つの内側面である。 On the other hand, at the other end 22b of the leg portion 22, the other end side outer surface 23b facing the inner surface 10b of the recess 10 is substantially flush with the outer surface 21b of the lid 21, and the inner surface 10b of the recess 10 The outer surface 21b of the cover 21 is spaced apart from the outer surface 21b of the cover 21 by a gap between the outer surface 21b and the outer surface 21b of the cover 21. Note that the outer surface 21a and the outer surface 21b of the lid portion 21 are two outer surfaces that intersect at a corner. The inner surface 10a and the inner surface 10b of the recess 10 are two inner surfaces that meet at a corner.

他端側外側面23bは、蓋部21の外側面21bから蓋部21の内側へ離れて設けられていてもよい。但し、一端側外側面23aと凹所10の内側面10aとの間の距離が、他端側外側面23bと凹所10の内側面10bとの間の距離よりも大きくなるように設けられる。 The other end side outer surface 23b may be provided away from the outer surface 21b of the lid 21 toward the inside of the lid 21. However, the distance between the outer side surface 23a on one end side and the inner side surface 10a of the recess 10 is set to be larger than the distance between the outer side surface 23b on the other end side and the inner side surface 10b of the recess 10.

上述のように、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の外側面23は、他端側外側面23bから中途部外側面23cへ向かうにつれて、蓋部21の外側面21bから蓋部21の内側へ離れ、蓋部21の外側面21aに接近する。逆に見て、脚部22の外側面23は、一端側外側面23aから中途部外側面23cへ向かうにつれて、蓋部21の外側面21aから蓋部21の内側へ離れ、蓋部21の外側面21bに接近する。 As described above, the leg portion 22 is formed in an arcuate shape that is convex toward the outside when viewed from the bottom surface. The outer surface 23 of the leg 22 moves away from the outer surface 21b of the lid 21 toward the inside of the lid 21 and approaches the outer surface 21a of the lid 21 as it goes from the other end outer surface 23b to the middle outer surface 23c. do. Conversely, the outer surface 23 of the leg 22 moves away from the outer surface 21a of the lid 21 toward the inside of the lid 21 as it goes from the one end outer surface 23a to the middle outer surface 23c. Approach the side surface 21b.

脚部22の外側面23と凹所10の内側面110との間の距離は、脚部22の一端部22aおよび他端部22bで小さく、脚部22の中途部22cにおいて大きくなっている。脚部22の外側面23と凹所10の内側面110との間には、通流路30が形成される。 The distance between the outer surface 23 of the leg 22 and the inner surface 110 of the recess 10 is small at one end 22a and the other end 22b of the leg 22, and is large at a midway portion 22c of the leg 22. A flow path 30 is formed between the outer surface 23 of the leg 22 and the inner surface 110 of the recess 10.

隣り合う2つの脚部22について見ると、一方の脚部22の一端部22aが、他方の脚部22の他端部22bと対向するように設けられている。蓋部21の四隅に設けられた4つの脚部22のうちから任意に隣り合う2つの脚部22を抽出した場合、いずれの場合も、一方の脚部22の一端部22aが他方の脚部22の他端部22bと対向するように設けられている(図5参照)。 Looking at the two adjacent leg parts 22, one end part 22a of one leg part 22 is provided so as to face the other end part 22b of the other leg part 22. When two adjacent legs 22 are arbitrarily extracted from among the four legs 22 provided at the four corners of the lid 21, in any case, one end 22a of one leg 22 is connected to the other leg. 22 (see FIG. 5).

図7を参照する。脚部22の底部は載置部12に接触しているので、通流路30は、底の部分が閉塞した状態となっている。通流路30には、凹所10の内側面110と蓋部21の外側面210との間の隙間から水が流れ込み、その後、脚部22の一端部22aおよび他端部22bから排水するように機能する。 See FIG. 7. Since the bottom of the leg portion 22 is in contact with the mounting portion 12, the bottom portion of the flow path 30 is in a closed state. Water flows into the flow path 30 from the gap between the inner surface 110 of the recess 10 and the outer surface 210 of the lid 21, and then drains from the one end 22a and the other end 22b of the leg 22. functions.

次に排水構造1の動作について説明する。図8を参照する。図8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8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の外側面210と凹所10の内側面110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110との間に流下する。 Next, the operation of the drainage structure 1 will be explained. Refer to FIG. FIG. 8 corresponds to a side view of the drain cover 20 placed in the recess 10. The water from the washing area floor 8 flows from the gap between the outer surface 210 of the lid part 21 of the drain cover 20 and the inner surface 110 of the recess 10 at the four corners 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 110 of the recess 10.

脚部22の外側面23と凹所10の内側面110との間の通流路30に流下した水は、一時的に通流路30に貯められつつ、脚部22の一端部22aおよび他端部22bにおける隙間から排水口11へ流れ出る。 The water that has flowed down into the passage 30 between the outer surface 23 of the leg 22 and the inner surface 110 of the recess 10 is temporarily stored in the passage 30 and flows through the one end 22a of the leg 22 and other parts. It flows out to the drain port 11 from the gap at the end 22b.

通流路30における水の流れは、図8に示す矢印Qのように、脚部22の外側面23と凹所10の内側面110との間の距離が大きい一端部22aへ向かう横方向への流れとなる。但し、脚部22の他端部22bにおいて脚部22の外側面23と凹所10の内側面110との間に隙間があるため、通流路30に流れ込んだ水の一部は、他端部22bにおける隙間からも排水口11へ流れ出る。 The flow of water in the passage 30 is in a lateral direction toward one end 22a where the distance between the outer surface 23 of the leg 22 and the inner surface 110 of the recess 10 is large, as indicated by the arrow Q shown in FIG. The flow is as follows. However, since there is a gap between the outer surface 23 of the leg 22 and the inner surface 110 of the recess 10 at the other end 22b of the leg 22, some of the water that has flowed into the flow path 30 is The water also flows out to the drain port 11 from the gap in the portion 22b.

通流路30に流れ込む水が少ない場合は、流れ込んだ水がすぐに脚部22の一端部22a側から流れ出すので、通流路30に貯えられる水は浅い状態となる。通流路30に流れ込む水が多くなると、脚部22の一端部22a側から流れ出す流量に限りがあるため、通流路30に貯えられる水は深くなる。 When there is little water flowing into the flow passage 30, the water that has flowed in immediately flows out from the one end 22a side of the leg portion 22, so that the water stored in the flow passage 30 becomes shallow. When the amount of water flowing into the passageway 30 increases, the amount of water flowing out from the one end 22a side of the leg portion 22 is limited, so the water stored in the passageway 30 becomes deeper.

脚部22が、蓋部21の外側面210よりも内側に形成されていることで、脚部22の外側面23と凹所10の内側面110との間に通流路30が設けられる。通流路30での水の流れによって髪の毛が運ばれるので、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。通流路30は、脚部22が、蓋部21の外側面210よりも内側に形成されていることで、底面が一定の広さを持っているため、狭小部分に水が停滞して髪の毛が付着するようなことが抑制される。 Since the leg portion 22 is formed inside the outer surface 210 of the lid portion 21, a flow path 30 is provided between the outer surface 23 of the leg portion 22 and the inner surface 110 of the recess 10. Since the hair is carried by the flow of water in the flow path 30, it is possible to suppress the hair contained in the water from adhering around the leg portions 22. The leg portion 22 of the flow path 30 is formed inside the outer surface 210 of the lid portion 21, so that the bottom surface has a certain width, so that water stagnates in the narrow portion and becomes dry. The adhesion of substances is suppressed.

図9を参照する。脚部22は、凹所10に設けられた排水口11の中央部から外側に向かう方向に交差するM方向に延びていることによって、対向する凹所10の内側面110との間で通流路30を設け易くなる。通流路30は、凹所10の四隅に設けられることによって、平面視において、凹所10の内側面110による2辺と、脚部22の外側面23による1辺とで囲まれる概ね三角形の領域として形成することができる。 See FIG. 9. The leg portions 22 extend in the M direction that intersects with the direction outward from the center of the drain port 11 provided in the recess 10, thereby allowing flow to flow between the inner surfaces 110 of the opposing recesses 10. This makes it easier to provide the passage 30. By being provided at the four corners of the recess 10, the flow path 30 has a generally triangular shape surrounded by two sides defined by the inner surface 110 of the recess 10 and one side defined by the outer surface 23 of the leg portion 22 in plan view. Can be formed as a region.

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矢印Rのように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。これによって、通流路30に流れ込んだ水が脚部22の通流路30側で滞留して髪の毛が付着することを抑制することができる。 The leg portions 22 are formed in an arc shape that is convex toward the outside in a cross section that intersects with the height direction, so that the direction of water flowing toward the leg portions 22 is lateral as shown by arrow R. It is possible to prevent the flowing water from staying in the flow path 30. This can prevent water flowing into the flow path 30 from staying on the flow path 30 side of the leg portion 22 and causing hair to adhere thereto.

図9に示すように、脚部22の一端部22aと凹所10の内側面110との間の隙間は、脚部22の他端部22bと凹所10の内側面110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部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。 As shown in FIG. 9, the gap between one end 22a of the leg 22 and the inner surface 110 of the recess 10 is the same as the gap between the other end 22b of the leg 22 and the inner surface 110 of the recess 10. It is wider than. Therefore, the water that has flowed into the flow passage 30 easily flows toward the end portion 22a, and a decrease in flow velocity can be suppressed.

隣り合う2つの脚部22では、一方の脚部22の一端部22aが他方の脚部22の他端部22bと対向するように設けられているため、図9に矢印Sで示すように排水口11の中央部から見て同じ周方向に脚部22から水が流れ出す。これによって、排水構造1は、排水口11において旋回流を発生させることができる。 In the two adjacent leg sections 22, one end 22a of one leg 22 is provided so as to face the other end 22b of the other leg 22, so that water can be drained as shown by arrow S in FIG. Water flows out from the legs 22 in the same circumferential direction when viewed from the center of the mouth 11. Thereby, the drainage structure 1 can generate a swirling flow at the drainage port 11.

図10を参照する。図10に示す変形例に係る排水カバー20では、隣り合う2つの脚部22では、一方の脚部22の一端部22aが他方の脚部22の一端部22aと対向するように設けられている。上述の実施形態と同様に、脚部22の一端部22aと蓋部21の外側面210との間の距離は、他端部22bと外側面210との間の距離よりも大きくなっている。
(Modified example)
See FIG. 10. In the drainage cover 20 according to the modification shown in FIG. 10, in two adjacent leg sections 22, one end 22a of one leg 22 is provided so as to face one end 22a of the other leg 22. . Similar to the embodiment described above, the distance between one end 22a of the leg 22 and the outer surface 210 of the lid 21 is larger than the distance between the other end 22b and the outer surface 210.

隣り合う脚部22の一端部22aの間では、両方の脚部22から図10に示す矢印Sのように水が流れ出す。これにより、排水構造1は、隣り合う脚部22の一端部22aの間で水の流速が増し、髪の毛や汚れの付着を抑制することができる。またヘアキャッチャー5に流れ込む水によって、ヘアキャッチャー5内に水平方向の軸まわりに旋回する旋回流が形成され得る。 Between the one end portions 22a of the adjacent leg portions 22, water flows out from both the leg portions 22 as indicated by the arrow S shown in FIG. Thereby, in the drainage structure 1, the flow rate of water increases between the one end portions 22a of the adjacent leg portions 22, and the adhesion of hair and dirt can be suppressed. Furthermore, the water flowing into the hair catcher 5 can form a swirling flow in the hair catcher 5 that swirls around a horizontal axis.

図11を参照する。図11に示す変形例に係る排水カバー20では、蓋部21の外側面210のうち、側辺部分に脚部22を設けている。脚部22の一端部22aと蓋部21の外側面210との間の距離は、他端部22bと外側面210との間の距離よりも大きくなっている。 Refer to FIG. 11. In the drainage cover 20 according to the modification shown in FIG. 11, legs 22 are provided on the side portions of the outer surface 210 of the lid portion 21. As shown in FIG. The distance between one end 22a of the leg 22 and the outer surface 210 of the lid 21 is larger than the distance between the other end 22b and the outer surface 210.

蓋部21の側辺部分に脚部22を設けた場合にも、脚部22を蓋部21の四隅に設けた場合と同様に、脚部22と凹所10の内側面110との間に通流路30を形成される。この場合も、図11に示す矢印Sのように、通流路30に流れ込んだ水が、脚部22の一端部22aから排出される排水構造とすることができる。 Even when the legs 22 are provided on the side portions of the lid 21, similar to the case where the legs 22 are provided at the four corners of the lid 21, there is a space between the legs 22 and the inner surface 110 of the recess 10. A flow path 30 is formed. In this case as well, a drainage structure may be provided in which water flowing into the flow passage 30 is discharged from one end 22a of the leg 22, as indicated by the arrow S shown in FIG.

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.
