Description

本発明は、洋風便器、小便器、洗面器、手洗器などの衛生陶器に係り、特に側面を伝わって流れ落ちる液がトイレルームや洗面室の床にまで伝わり落ちないようにするための凹段部が該側面に設けられた衛生陶器に関する。 The present invention relates to sanitary ware such as Western-style toilets, urinals, basins, hand-washing basins and the like, and in particular, a stepped portion for preventing liquid flowing down along the side from being transmitted to the floor of a toilet room or lavatory. Relates to sanitary ware provided on the side surface.

洋風便器の側面に尿の飛沫が掛かり、これがトイレルームの床面にまで伝わり落ちると、洋風便器の底面と床面との間に染み込み、拭いても取れない臭気源となる。 When urine splashes on the side of the Western-style toilet and reaches the floor surface of the toilet room, it penetrates between the bottom surface of the Western-style toilet and the floor surface, resulting in an odor source that cannot be removed by wiping.

特開２００２−３２２７１８号の図５には、洋風便器のスカート部の下部に凹段部を設け、この凹段部の入口部に水切り突部を下方に向って突設した洋風便器が記載されている。凹段部よりも上側の側面を伝わり流れてきた汚水は、この水切り突部から下方に滴下するため、洋風便器の底面とトイレルームの床面との間に染み込まない。 FIG. 5 of Japanese Patent Application Laid-Open No. 2002-322718 describes a Western-style toilet in which a concave step portion is provided at the lower portion of the skirt portion of a Western-style toilet, and a draining projection is protruded downward at the entrance portion of the concave step portion. ing. Since the sewage that has flowed along the side surface above the concave step portion drops downward from the draining projection, it does not penetrate between the bottom surface of the Western-style toilet and the floor surface of the toilet room.

実公平７−２５１０５号の図４には、洗面ボウルの前縁部の下縁に同様の水切り用の突部を下方に向って突設することが記載されている。洗面ボウルの外面を伝わり落ちてきた水は、この突部から下方に滴下する。
特開２００２−３２２７１８号実公平７−２５１０５号 In FIG. 4 of Japanese Utility Model Publication No. 7-25105, it is described that a similar draining protrusion is provided to project downward on the lower edge of the front edge of the wash bowl. The water that has fallen along the outer surface of the wash bowl drops downward from this protrusion.
JP 2002-322718 A No. 7-25105

上記従来技術では、上方から洋風便器や洗面ボウルの外面を伝わり流れてきた水が部屋の床面に滴下し、床を汚すことになる。 In the above prior art, the water that has flowed from the upper side of the Western-style toilet bowl and the outer surface of the wash bowl drops on the floor of the room and soils the floor.

本発明は、側面に凹段部を設けた衛生陶器において、側面を伝わり落ちてきた液体が凹段部よりも下方に伝わり流れることがなく、しかも凹段部から滴下することもない衛生陶器を提供することを目的とする。 The present invention relates to a sanitary ware having a recessed step portion on the side surface, and the sanitary ware in which the liquid that has fallen along the side surface does not flow below the recessed step portion and does not flow, and is not dripped from the recessed step portion. The purpose is to provide.

請求項１の衛生陶器は、側面の下部に凹段部を設けた衛生陶器において、該凹段部の天井面は、該凹段部の入口側から凹段部の奥に向って傾斜角７°以下の下り勾配の傾斜面を有しており、該傾斜面の入口側から奥側への幅が２５ｍｍ以上であることを特徴とするものである。 The sanitary ware according to claim 1 is a sanitary ware in which a concave step portion is provided at a lower portion of a side surface, and the ceiling surface of the concave step portion is inclined at an inclination angle 7 from the entrance side of the concave step portion toward the back of the concave step portion. It has an inclined surface with a downward slope of less than or equal to 0 °, and the width from the inlet side to the back side of the inclined surface is 25 mm or more.

請求項２の衛生陶器は、請求項１において、該凹段部の奥壁面と前記天井面との交叉隅部は、凹曲面となっていることを特徴とするものである。 A sanitary ware according to a second aspect is characterized in that, in the first aspect, the intersection corner between the back wall surface of the concave step portion and the ceiling surface is a concave curved surface.

請求項３の衛生陶器は、請求項１又は２において、前記凹段部の直上の前記側面と前記天井面との交叉部は凸曲面となっており、該側面は該凸曲面のみを介して該天井面の前記傾斜面に連なっていることを特徴とするものである。 The sanitary ware according to claim 3 is the sanitary ware according to claim 1 or 2, wherein the intersection of the side surface directly above the concave step portion and the ceiling surface is a convex curved surface, and the side surface is interposed only through the convex curved surface. It is connected to the inclined surface of the ceiling surface.

請求項４の衛生陶器は、請求項１ないし３のいずれか１項において、前記衛生陶器は便器、洗面器又は手洗器であることを特徴とするものである。 A sanitary ware according to a fourth aspect is the sanitary ware according to any one of the first to third aspects, wherein the sanitary ware is a toilet bowl, a wash basin or a hand-washing basin.

請求項５の衛生陶器は、請求項１ないし４のいずれか１項において、施釉された陶器製であることを特徴とするものである。 A sanitary ware according to a fifth aspect is characterized in that, in any one of the first to fourth aspects, the sanitary ware is made of glazed earthenware.

本発明の衛生陶器にあっては、その側面を伝わり落ちてきた液体が該側面から凹段部の天井面に伝わって回り込む。この天井面は、奥に向って７°以下と緩く傾斜した傾斜面となっており、しかもこの傾斜面は２５ｍｍ以上の十分な幅を有している。このため、側面から凹段部天井面に回り込んできた液は、この傾斜面をゆっくりと伝わりながら奥に向って移動し、この間に液が蒸発して乾燥する。 In the sanitary ware of the present invention, the liquid that has fallen along the side surface is transferred from the side surface to the ceiling surface of the concave step portion. This ceiling surface is an inclined surface that is gently inclined at 7 ° or less toward the back, and this inclined surface has a sufficient width of 25 mm or more. For this reason, the liquid that has entered the ceiling surface of the concave step portion from the side surface moves toward the back while slowly traveling along the inclined surface, and during this time, the liquid evaporates and dries.

この結果、液が凹段部の奥壁面にまで達することがなく、該奥壁面を伝って液がさらに下方にまで伝わり落ちることが防止される。 As a result, the liquid does not reach the back wall surface of the concave step portion, and the liquid is prevented from being transmitted further down along the back wall surface.

本発明では、このように凹段部の天井面において液が蒸発乾固するので、この天井面は適宜拭き掃除されることが望ましい。凹段部の天井面と奥壁面との交叉隅部を凹曲面としておくと、この交叉隅部まで十分に拭き掃除することができ、天井面の汚れを隅々まで容易に除去することができる。 In the present invention, since the liquid evaporates and dries on the ceiling surface of the concave step portion in this way, it is desirable that the ceiling surface is appropriately wiped and cleaned. If the intersection corner between the ceiling surface and the back wall surface of the concave step portion is a concave curved surface, the intersection corner can be sufficiently wiped and cleaned, and the dirt on the ceiling surface can be easily removed from corner to corner.

この交叉隅部の曲率半径は５ｍｍ以上であることが好ましい。 The radius of curvature of the intersection corner is preferably 5 mm or more.

本発明では、凹段部の直上の衛生陶器側面と凹段部天井面との交叉部は、凸曲面となっており、該側面は該凸曲面のみを介して該天井面の前記傾斜面に連なっている構成としてもよい。このように構成することにより、凹段部よりも上方の側面から伝わり流れてきた液が天井面に確実に回り込むようになる。この凸曲面の曲率半径が大きくなると、該上方の側面から伝わってきた液が該天井面に伝わり易くなる。具体的には、この凸曲面の曲率半径は３ｍｍ以上であることが好ましい。 In the present invention, the intersection between the side surface of the sanitary ware immediately above the recessed step portion and the ceiling surface of the recessed step portion is a convex curved surface, and the side surface is connected to the inclined surface of the ceiling surface only through the convex curved surface. It is good also as a structure which continues. By comprising in this way, the liquid which has flowed from the side surface above the recessed step portion flows around the ceiling surface with certainty. When the curvature radius of the convex curved surface is increased, the liquid transmitted from the upper side surface is easily transmitted to the ceiling surface. Specifically, the radius of curvature of the convex curved surface is preferably 3 mm or more.

本発明の衛生陶器は、施釉された陶器製であることが好ましい。このように施釉されていると、液が衛生陶器に染み込むことが防止される。なお、上記のように天井面は傾斜面としているので釉薬がかかりやすく、さらに凹段部の天井面と奥壁面との交叉隅部を曲率半径の大きい凹曲面とした場合、この交叉隅部にも十分に釉が掛かるようになり、交叉隅部でも汚水の染み込みが確実に防止される。 The sanitary ware of the present invention is preferably made of glazed pottery. When glazed in this way, the liquid is prevented from soaking into sanitary ware. In addition, since the ceiling surface is inclined as described above, it is easy to apply glaze, and if the intersection corner between the ceiling surface and the back wall surface of the concave step portion is a concave curved surface with a large curvature radius, As a result, the water will be sufficiently dredged, and the infiltration of sewage is surely prevented even at the crossing corner.

以下、図面を参照して実施の形態について説明する。第１図は実施の形態に係る洋風便器を示すものであり、（ａ）図は斜視図、（ｂ）図は（ａ）図のＢ−Ｂ線断面図、（ｃ）図は（ｂ）図の拡大図である。 Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a Western-style toilet according to an embodiment, wherein (a) is a perspective view, (b) is a sectional view taken along line BB in (a), and (c) is (b). It is an enlarged view of a figure.

施釉された陶器製の洋風便器１は、前方及び左右側方の側面の下部に凹段部３設けられている。この凹段部３は、側面２から凹段部の天井面に回り込む凸に湾曲した凸湾曲部３ａと、該凸湾曲部３ａに引き続いている該傾斜面３ｂと、該天井面と凹段部の奥壁面との交叉隅部を構成する凹湾曲面３ｃと、該奥壁面３ｄとで構成されている。奥壁面３ｄの下部は、洋風便器１の下端にまで達している。 The glazed porcelain western style toilet 1 is provided with a concave step 3 at the lower part of the front and left and right side surfaces. The concave step portion 3 includes a convex curved portion 3a curved from the side surface 2 to the ceiling surface of the concave step portion, the inclined surface 3b following the convex curved portion 3a, the ceiling surface and the concave step portion. It is composed of a concave curved surface 3c that constitutes a crossing corner with the back wall surface and the back wall surface 3d. The lower part of the back wall surface 3 d reaches the lower end of the western-style toilet 1.

この実施の形態では、この傾斜面３ｂによって凹段部３の天井面が構成されている。 In this embodiment, the inclined surface 3b constitutes the ceiling surface of the recessed step portion 3.

この傾斜面３ｂは、凸湾曲部３ａから凹湾曲部３ｃに向って下り勾配であり、且つ水平面に対する傾斜角度θが７°以下、好ましくは１〜７°、特に好ましくは２〜５°である。本発明では、この傾斜角度が７°以下である範囲が傾斜面３ｂとして定義される。 The inclined surface 3b is downwardly inclined from the convex curved portion 3a toward the concave curved portion 3c, and the inclined angle θ with respect to the horizontal plane is 7 ° or less, preferably 1 to 7 °, particularly preferably 2 to 5 °. . In the present invention, a range in which the inclination angle is 7 ° or less is defined as the inclined surface 3b.

傾斜面３ｂの幅（凸湾曲部３ａから凹湾曲部３ｃに向う方向の水平方向の長さ）Ｌは２５ｍｍ以上、例えば２５〜５０ｍｍ好ましくは３０〜４０ｍｍである。 The width of the inclined surface 3b (the horizontal length in the direction from the convex curved portion 3a to the concave curved portion 3c) L is 25 mm or more, for example, 25 to 50 mm, preferably 30 to 40 mm.

凸湾曲部３ａの曲率半径Ｒ_１は好ましくは３〜１０ｍｍである。凹湾曲部３ｂの曲率半径Ｒ_２は好ましくは５〜１０ｍｍである。 The radius of curvature _{R 1} of the convex curved portion 3a is preferably 3 to 10 mm. The radius of curvature _{R 2} of the concave curve portion 3b is preferably 5 to 10 mm.

なお、第１図の符号４は便鉢、５は便座取付ボルトの通し孔を示す。 In addition, the code | symbol 4 of FIG. 1 shows the toilet bowl, 5 shows the through-hole of the toilet seat mounting bolt.

このように構成された洋風便器１においては、側面２に付着した小水などの液は、該側面２を伝わり流れ、凹段部３に達する。この液は、凸湾曲部３ａを回り込んで傾斜面３ｂに達し、該傾斜面３ｂを凹湾曲部３ｃに向ってゆっくりと流れる。この傾斜面３ｂが２５ｍｍ以上の幅Ｌを有し、しかも傾斜角度が７°以下と緩い傾斜となっているため、水滴となりにくく、傾斜面３ｂに達した液はゆっくりと凹湾曲部３ｃに向って伝わり流れ、この間に蒸発して乾燥する。 In the Western-style toilet 1 configured as described above, liquid such as small water attached to the side surface 2 flows along the side surface 2 and reaches the concave step portion 3. This liquid wraps around the convex curved portion 3a and reaches the inclined surface 3b, and slowly flows through the inclined surface 3b toward the concave curved portion 3c. Since the inclined surface 3b has a width L of 25 mm or more and has a gentle inclination of an inclination angle of 7 ° or less, it is difficult to form water droplets, and the liquid that has reached the inclined surface 3b slowly moves toward the concave curved portion 3c. And then evaporate and dry.

この結果、液が凹段部３の奥壁面３ｄにまで達することがなく、該奥壁面３ｄを伝って液がさらに下方にまで伝わり落ちることが防止される。 As a result, the liquid does not reach the back wall surface 3d of the recessed step portion 3, and the liquid is prevented from being transmitted further down through the back wall surface 3d.

この実施の形態では、このように凹段部の傾斜面３ｂにおいて液が蒸発乾固するので、この傾斜面３ｂは適宜拭き掃除されることが望ましい。この実施の形態では、凹段部の傾斜面３ｂと奥壁面３ｄとの交叉隅部が凹湾曲面３ｃとなっているので、この交叉隅部まで十分に拭き掃除することができ、凹段部３の天井面の汚れを隅々まで容易に除去し、臭気源となることを防止することができる。 In this embodiment, since the liquid evaporates and dries on the inclined surface 3b of the concave step portion, it is desirable that the inclined surface 3b is appropriately wiped and cleaned. In this embodiment, since the intersection corner between the inclined surface 3b of the concave step portion and the back wall surface 3d is the concave curved surface 3c, the cross corner portion can be sufficiently wiped and cleaned. It is possible to easily remove all the dirt on the ceiling surface of the wall and prevent it from becoming an odor source.

なお、第２図の凹段部３’のように、凹湾曲部３ｃの曲率半径を大きくするほど、この交叉隅部の清掃が容易となる。ただし、この凹湾曲部３ｃの曲率半径を大きくすると、奥壁面３ｄが過度に後退することになる。このため、曲率半径Ｒ_２は１０ｍｍ以下にすることが望ましい。 In addition, like the concave step portion 3 ′ in FIG. 2, the larger the radius of curvature of the concave curved portion 3c, the easier the cleaning of the crossing corner portion becomes. However, if the curvature radius of the concave curved portion 3c is increased, the back wall surface 3d is excessively retracted. Therefore, the radius of curvature _{R 2} is preferably set to 10mm or less.

また、傾斜面３ｂのトイレルーム床面からの高さは１５ｍｍ以上であることが、清掃し易く、好ましい。ただし、傾斜面３ｂが過度に高位置であると、洋風便器１の美観を損うおそれがあり、また、男子小水が凹段部３内に直に掛かるおそれも出てくるので、傾斜面３ｂのトイレルーム床面からの高さは１００ｍｍ以下とするのが好ましい。 Moreover, it is easy to clean that the height from the toilet room floor surface of the inclined surface 3b is 15 mm or more, and it is preferable. However, if the inclined surface 3b is excessively high, the aesthetic appearance of the Western-style toilet 1 may be impaired, and there is also a risk that the boy's water will be directly applied to the recessed step portion 3. The height from the toilet room floor of 3b is preferably 100 mm or less.

この実施の形態では、凸湾曲部３ａの曲率半径を１０ｍｍ以上と大きくしているため、凹段部３よりも上方の側面２から伝わり流れてきた液が凸湾曲部３ａを確実に回り込んで傾斜面３ｂに達する。即ち、側面２を伝わってきた液が、凹段部３内に伝わらずにそのままトイレルーム床面に滴下することが防止される。 In this embodiment, since the curvature radius of the convex curved portion 3a is increased to 10 mm or more, the liquid that has flowed from the side surface 2 above the concave step portion 3 surely wraps around the convex curved portion 3a. It reaches the inclined surface 3b. That is, the liquid that has traveled along the side surface 2 is prevented from dropping on the floor surface of the toilet room without being transmitted into the recessed step portion 3.

この実施の形態では、洋風便器１は施釉されているため、液が衛生陶器に染み込むことが防止される。なお、上記のように凹湾曲部３ｃの曲率半径を大きくすることにより、この凹湾曲部３ｃにも十分に釉が掛かるようになり、該凹湾曲部３ｃでも汚水の染み込みが確実に防止される。 In this embodiment, since the Western-style toilet bowl 1 is glazed, the liquid is prevented from soaking into the sanitary ware. In addition, by increasing the curvature radius of the concave curved portion 3c as described above, the concave curved portion 3c is sufficiently wrinkled, and the concave curved portion 3c is reliably prevented from seeping in sewage. .

なお、第１図では凹段部３は洋風便器１の後部側面にまで延設されているが、前部側の下部にのみ設けられてもよい。 In FIG. 1, the recessed step portion 3 extends to the rear side surface of the western style toilet 1, but it may be provided only at the lower portion on the front side.

上記実施の形態は洋風便器に係るものであるが、本発明は第３図に示す小便器や、第４図に示す洗面器などにも適用できる。また、図示は省略するが手洗器などにも適用できる。 Although the above embodiment relates to a Western style toilet, the present invention can be applied to the urinal shown in FIG. 3, the basin shown in FIG. Although not shown, the present invention can also be applied to a hand-washer.

第３図（ａ）、（ｂ）の施釉された陶器製小便器１０では、下部に凹段部１１が設けられている。拡大した図示は省略するが、この凹段部１１も第１図（ｃ）と同様に、小便器１１の側面１２に連なる凸湾曲部と、それに引き続く傾斜面と、該傾斜面に引き続く凹湾曲部と、奥壁面とを備えている。 In the glazed ceramic urinal 10 shown in FIGS. 3 (a) and 3 (b), a concave step portion 11 is provided at the lower portion. Although the enlarged illustration is omitted, the concave step portion 11 also has a convex curved portion that continues to the side surface 12 of the urinal 11, a subsequent inclined surface, and a concave curve that continues to the inclined surface, as in FIG. And a back wall surface.

この傾斜面の傾斜角度や幅、凸湾曲部及び凹湾曲部の曲率半径の好適な範囲は第１図の場合と同様である。この実施の形態においても、凹段部１１を設けたことにより、第１図の場合と同様に、小便器１０の側面１２に掛った小水などが側面１２から凹段部１１に回り込んで蒸発するようになる。そして、側面１２からトイレルームの床面に直に落下することが防止される。 The preferred range of the inclination angle and width of the inclined surface, and the radius of curvature of the convex and concave curved portions are the same as in FIG. Also in this embodiment, by providing the concave step portion 11, as in the case of FIG. 1, small water or the like on the side surface 12 of the urinal 10 wraps around the concave step portion 11 from the side surface 12. It will evaporate. And it is prevented that it falls directly from the side surface 12 to the floor surface of a toilet room.

第４図（ａ）は洗面器２２を備えた洗面キャビネット１０の斜視図、第４図（ｂ）は第４図（ａ）のＢ−Ｂ断面図、第４図（ｃ）は凹段部の拡大断面図である。 4 (a) is a perspective view of a wash cabinet 10 provided with a wash basin 22, FIG. 4 (b) is a cross-sectional view taken along the line BB of FIG. 4 (a), and FIG. 4 (c) is a concave step. FIG.

この洗面キャビネット１０は、キャビネット本体２１と、該キャビネット本体２１の上面部に設置された施釉された陶器製の洗面器２２とを有する。キャビネット本体２１の前面には開閉式の扉２４が設けられている。この扉２４の上側は幕前板２３となっている。洗面器２２の前縁側は、上方ほどせり出す膨出部となっている。この膨出部の下部に凹段部２５が設けられている。この凹段部２５は、洗面器２２の下縁部の略鉛直な前側面２２ａから後方に後退している。 The wash cabinet 10 includes a cabinet body 21 and a glazed ceramic wash basin 22 installed on the upper surface of the cabinet body 21. An openable / closable door 24 is provided on the front surface of the cabinet body 21. The upper side of the door 24 is a front curtain plate 23. The front edge side of the basin 22 is a bulging portion that protrudes upward. A recessed step portion 25 is provided at the lower portion of the bulging portion. The recessed step portion 25 is retracted backward from the substantially vertical front side surface 22 a of the lower edge portion of the basin 22.

この凹段部２５は、前側面２２ａに連なる凸湾曲部２５ａと、該凸湾曲部２５ａに連なる傾斜面２５ｂと、該傾斜面２５ｂに連なる凹湾曲部２５ｃと、この凹湾曲部２５ｃに連なる奥壁面２５ｄとからなる。奥壁面２５ｄは幕前板２３に接している。 The concave step portion 25 includes a convex curved portion 25a continuous with the front side surface 22a, an inclined surface 25b continuous with the convex curved portion 25a, a concave curved portion 25c continuous with the inclined surface 25b, and a back continuous with the concave curved portion 25c. It consists of a wall surface 25d. The back wall surface 25 d is in contact with the front curtain plate 23.

傾斜面２５ｂは、奥に向って下り勾配であり、その水平面に対する傾斜角度θは７°以下である。傾斜角度θ、凸湾曲部２５ａ及び凹湾曲部２５ｂの曲率半径、傾斜面２５ｂの幅Ｌの好ましい範囲はいずれも第１図の場合と同様である。 The inclined surface 25b has a downward slope toward the back, and the inclination angle θ with respect to the horizontal plane is 7 ° or less. The preferable ranges of the inclination angle θ, the radius of curvature of the convex curved portion 25a and the concave curved portion 25b, and the width L of the inclined surface 25b are all the same as in FIG.

なお、前側面２２ａの前面は、扉２４の前面と面一か、それよりも若干前方に位置している。 Note that the front surface of the front side surface 22a is flush with the front surface of the door 24, or slightly forward of it.

この実施の形態でも、洗面器２２の前面を伝わってきた水は凸湾曲部２５ａから傾斜面２５ｂに回り込み、奥壁面２５ｄに向ってゆっくりと伝わり流れ、この間に蒸発する。このため、洗面室の床に直に落下したり、扉２４の前面に掛ったりすることが防止される。 Also in this embodiment, the water that has traveled along the front surface of the basin 22 wraps around the inclined surface 25b from the convex curved portion 25a, flows slowly toward the back wall surface 25d, and evaporates during this time. For this reason, falling directly on the floor of the washroom or hanging on the front surface of the door 24 is prevented.
