Description

本発明は水洗小便器、特に、使用者の排尿を受ける受面部をボール部から立設させ、洗浄水で受面部とボール部の内面を洗浄する水洗小便器に関する。 The present invention relates to a flush urinal, and more particularly, to a flush urinal in which a receiving surface portion that receives a user's urine is erected from a ball portion, and the receiving surface portion and the inner surface of the ball portion are washed with cleaning water.

従来、水洗小便器はその正面部分に立設させて使用者が排出する尿を受けて下方に流す受面部と、受面部下部に連接され尿と洗浄水を集めて排水口から排出するボール部とを一体に形成して備える。水洗小便器には壁掛式のものと床置式のものがあるが、いずれの場合も受面部はある高さを必要とするため、特に床置式では小便器全体として比較的に長大なものとなる。このことは水洗小便器の搬送時や取付作業の際に利便性の妨げともなる。 Conventionally, a flush urinal is erected on the front part of the urinal to receive urine discharged by the user and flow downward, and a ball part connected to the lower part of the receiving part to collect urine and washing water and discharge it from the drain And are formed integrally. There are wall-mounted and floor-mounted flush urinals, but in both cases the receiving surface requires a certain height, so the floor urinal as a whole is relatively long. . This also hinders convenience during transport of the flush toilet or during installation work.

水洗小便器の洗浄水は通常、外部水道管から弁装置を介して受面部の上部に供給され、散水路やスプレッダー等によって受面部内周面とボール部内周面に拡散され、洗浄を行う。従前は、受面部の左右側壁先端面やボール部の周壁上端面は内側に折り返して洗浄水を外に逃がさないリム部を形成していたので、内周の略全面を洗浄し得たが、逆に左右側壁先端面やボール部の周壁上端面はリム部で幅の広いものとなり、排尿時に飛散する尿滴が付着しやすく、水洗不能の汚染領域となっていた。近時、幅広のリム部は撤廃され、周壁の厚さのみによる幅の狭い端面を備える薄縁の水洗小便器が主流となり、小便器の洗浄装置としてスプレッダーが用いられているが、この方式の水洗小便器では、洗浄水の外への飛び出しを防止することが求められる様になった(特許文献1参照)。従って近時の水洗小便器では、ボール部外への洗浄水の飛び出しや落下を避けるため、端面まで洗浄水を流せず、結果として端部近傍に非洗浄域を作ることになり、飛散尿滴による汚染領域を、特に受面部側壁の内面に広げる結果となっている。 Wash water of the flush toilet is usually supplied to the upper part of the receiving surface part from the external water pipe through the valve device, and is diffused to the inner peripheral surface of the receiving surface part and the inner peripheral surface of the ball part by a watering channel or a spreader to perform cleaning. Previously, the front end surface of the left and right side walls of the receiving surface portion and the upper end surface of the peripheral wall of the ball portion were folded inward to form a rim portion that did not allow cleaning water to escape outside, so it was possible to clean substantially the entire inner periphery, On the contrary, the front end surfaces of the left and right side walls and the upper end surface of the peripheral wall of the ball portion are wide at the rim portion, and urine droplets scattered during urination are likely to adhere, resulting in a contaminated area that cannot be washed with water. Recently, wide rims have been abolished, and thin-edged flush toilets with narrow end faces due only to the thickness of the peripheral wall have become the mainstream, and spreaders are used as flushing devices for urinals. In the urinal, it has been required to prevent the washing water from jumping out (see Patent Document 1). Therefore, in recent flush urinals, in order to avoid the flushing and dropping of the washing water to the outside of the ball part, the washing water does not flow to the end surface, and as a result, a non-washing area is created in the vicinity of the end part. As a result, the contamination area caused by the above is spread on the inner surface of the side wall of the receiving surface.

水洗小便器には、上記の通り、ボール部周壁の上端面の尿滴汚れを洗浄する機能がなく、排尿時に飛散して周壁上端面に付着し周壁外周壁面を流下する尿滴は床面まで汚すが、これらへの対策としては人手によるボール部上端面や床面の清掃しかなかった。この点に着目して、本発明者らは、ボール部上端面の下部に通水路を設け、上端面のほぼ全長の表面に開口する溢水口から通水路に供給した洗浄水を溢水させて水膜流としてボール部周壁の内外周面を洗浄させ、外周面を洗浄した水膜流は外周面上部から通水路の下を通ってボール部内方に斜降する隙間で構成する収水路を介してボール部内に収容されるようにした縁洗浄型の水洗便器洗浄方式と水洗便器を提案した（特許文献２参照）。なお、この型における収水路の構成は、溢水水膜流がなくとも、ボール部上端面から外周面に沿って自然流下する尿滴をボール部内方に収容するように機能するので、ボール部の上端面とそれに続く外周面については有用な構成であるが、受面部側壁内面の水洗不能領域については課題を残す。 As described above, the flush urinal does not have the function of cleaning the urine droplets on the upper surface of the peripheral wall of the ball, and the urine droplets scattered during urination and adhering to the upper surface of the peripheral wall and flowing down the peripheral wall of the peripheral wall reach the floor surface. As a countermeasure against these problems, there was only manual cleaning of the upper end surface of the ball part and the floor surface. Focusing on this point, the present inventors have provided a water passage at the lower part of the upper end surface of the ball portion, and overflowed the washing water supplied to the water passage from the overflow opening opened on the surface of almost the entire upper end surface. The inner and outer peripheral surfaces of the ball peripheral wall are washed as a film flow, and the water film flow that has washed the outer peripheral surface passes through a water collecting path that is formed by a gap that descends inward from the upper part of the outer peripheral surface to the inside of the ball part. An edge cleaning type flush toilet cleaning system and flush toilet that are accommodated in the ball portion have been proposed (see Patent Document 2). In addition, the structure of the water collecting channel in this type functions so as to accommodate urine droplets that naturally flow down from the upper end surface of the ball portion along the outer peripheral surface inside the ball portion even when there is no overflow water film flow. The upper end surface and the outer peripheral surface following the upper end surface are useful configurations, but problems remain with respect to the unwashable region on the inner surface of the receiving surface portion side wall.

特許文献１の水洗式小便器とその洗浄装置においては、スリット状射水孔をスプレッダー下方の左右方向に沿って設ける等により、給水圧の変動等で流量が変化しても洗浄水が外に飛び出すことを防止し、水洗小便器の下部に段部を設け、ボール部内面を洗浄しているが、受面部においては段部から側壁端面までの内壁面、ボール部においても周壁上端面から段部までの内壁面、更には尿滴の飛散が及ぶ各々の端面までは洗浄水が導かれず洗浄されない。水洗不能領域として残るボール部周壁と受面部両側壁の端面と、これら端面に続く内外周面とを、洗浄水が便器の外に飛んだり流れたりしないようにして洗浄可能とすることが本発明の課題の一つとなる。ここで、ボール部周壁の端面に関する上記の縁洗浄型水洗小便器の技術が利用可能であるが、その利用に当たっては次の点を考慮する必要がある。 In the flush-type urinal and the washing apparatus of Patent Document 1, the washing water jumps out even if the flow rate changes due to fluctuations in the water supply pressure or the like by providing slit-shaped spray holes along the left-right direction below the spreader. In order to prevent this, a step is provided at the bottom of the flush urinal to clean the inner surface of the ball part, but the inner surface from the step part to the side wall end face is received at the receiving part, and the step part from the upper end surface of the peripheral wall is also provided at the ball part Washing water is not guided to the inner wall surfaces up to and to the respective end surfaces where the urine droplets are scattered, and is not washed. The present invention makes it possible to wash the peripheral wall of the ball portion and the both side walls of the receiving surface portion remaining as the non-washable region and the inner and outer peripheral surfaces following these end surfaces so that the wash water does not fly or flow out of the toilet. One of the challenges. Here, the technique of the above-described edge-washing flush toilet relating to the end face of the peripheral wall of the ball portion can be used. However, the following points need to be taken into consideration when using the technique.

特許文献２の縁洗浄型水洗小便器においては、ボール部周壁の上端面に溢水水膜流を通水路の略全長にわたって実質的に均一に発生させることにより、上端面に続くボール部周面の均一で効果的洗浄を行うが、そのためにはボール部上端面が均一な高さで水平となるように便器を取付けることが重要である。ここでは縁洗浄型水洗小便器を、床面又は壁面に対して、ボール部周壁の上端面が水平となるように取付ける際に生じる問題が本発明の他の課題の一つとなる。ただし、本発明においては、水洗小便器自体が持つ形状についての問題、つまり、ボール部から延長して立設させた受面部による重量配分の不均衡性で生じる、便器の水平設置の難しさや取付けの際の取り扱い上の不便さを考慮すると同時に、受面部の水洗不能領域をなくすための方策を考慮する。また、ボール部周壁上端面を縁洗浄型とした場合、特に上端面とそれに続く外周面が洗浄水で濡れた状態になるため、使用者に衣服が濡れる恐れを抱かせることになるが、この恐れを払拭あるいは軽減する必要がある。 In the edge washing type flush toilet of Patent Document 2, an overflow water film flow is generated substantially uniformly over the entire length of the water channel on the upper end surface of the ball portion peripheral wall, so that the ball portion peripheral surface following the upper end surface is generated. Although uniform and effective cleaning is performed, it is important to attach a toilet so that the upper end surface of the ball portion is horizontal at a uniform height. Here, another problem of the present invention is a problem that occurs when the edge-washing flush toilet is attached to the floor surface or wall surface so that the upper end surface of the ball portion peripheral wall is horizontal. However, in the present invention, the problem with the shape of the flush urinal itself, that is, the difficulty of horizontal installation of the toilet and the mounting caused by the imbalance in the weight distribution due to the receiving surface part extending from the ball part. Considering the inconvenience in handling at the same time, measures to eliminate the non-washable area of the receiving surface are also considered. In addition, when the upper edge surface of the ball part peripheral wall is an edge cleaning type, the upper end surface and the outer peripheral surface that follows are particularly wet with the cleaning water, which may cause the user to get wet with clothes. It is necessary to eliminate or reduce fear.

従って、本発明はボール部から立設させた受面部を備えることによる取付け作業時の不便さを取除くと同時に、特に縁洗浄型としてボール部や受面部の上端面に水膜流を発生する構成を有するものとした場合、ボール部や受面部の上端面が水平となるように容易に取付け可能とする構成とした水洗小便器を提供することを第１の目的とする。更に、ボール部と受面部から洗浄不能領域をなくした水洗小便器を提供することを第２の目的とし、縁洗浄型とすることによって使用時に濡れているボール部上端面とその外周壁が使用者の不安とならないようにした水洗小便器の提供を第３の目的とする。 Therefore, the present invention eliminates the inconvenience at the time of mounting work by providing the receiving surface portion standing upright from the ball portion, and at the same time generates a water film flow on the upper end surface of the ball portion and the receiving surface portion, particularly as an edge cleaning mold. In the case of having the configuration, a first object is to provide a flush urinal that can be easily attached so that the upper end surfaces of the ball portion and the receiving surface portion are horizontal. Furthermore, the second object is to provide a flush urinal in which the non-cleanable area is eliminated from the ball portion and the receiving surface portion, and the upper edge surface of the ball portion and its outer peripheral wall that are wet during use by using an edge cleaning type are used. A third purpose is to provide a flush toilet that does not cause anxiety.

本発明によれば、底部に排水口を持つボール部から立ち上げて使用者の排尿を受けるようにした受面部を備えてなる水洗小便器の受面部をボール部から分離して作成し、便器の取付け位置にそれぞれ取付けたときに互いに組合わされるようにしたので、例えばボール部は、受面部の重量と形状と関わりの無い軽量さと簡潔さをもって壁面に取付けることが出来、ボール部上端面を縁洗浄型としたときは上端面の水平取付け作業を容易とする。受面部がボール部の重量と容量から切り離されて別個に用意されることによって初めて両者は同一寸法という制約を外され、上面より見て受面部の少なくとも下端部内周面がボール部内に位置するという寸法上の選択を容易に可能とする。受面部の下端部がボール部内に在ることによって、受面部全面から流下する洗浄水をボール部内に収容可能となり、受面部内周面全域の洗浄、更には受面部の外周面の洗浄も可能となる。 According to the present invention, a receiving surface portion of a flush toilet comprising a receiving surface portion that is raised from a ball portion having a drain outlet at the bottom to receive a user's urine is prepared separately from the ball portion, For example, the ball part can be attached to the wall surface with light weight and simplicity that are not related to the weight and shape of the receiving surface part. When the edge cleaning type is adopted, the horizontal mounting work of the upper end surface is facilitated. Only when the receiving surface portion is separated from the weight and capacity of the ball portion and prepared separately, both are removed from the restriction of the same size, and at least the inner peripheral surface of the lower end portion of the receiving surface portion is located in the ball portion when viewed from the upper surface. Easy selection of dimensions. Since the lower end of the receiving surface is in the ball, cleaning water that flows down from the entire surface of the receiving surface can be stored in the ball, and the entire inner surface of the receiving surface can be cleaned, and the outer peripheral surface of the receiving surface can also be cleaned. It becomes.

一方、受面部をボール部から分離して作成し、便器の取付け位置にそれぞれ取付けたときに互いに組合わされるようにした水洗小便器において、上面図では外周部がボール部外周部と略同形状の環状体をボール部上端面との間に隙間を開けて配置させ、環状体の上端面に続く外周壁面を上端面より下方においてボール部外周壁面から内方に引込ませ、環状体とボール部上端面との間に、環状体の上端面からその外周壁面を流下する尿滴の流れを阻害しない隙間（以降、この隙間を収水路と表現）を作り、自力流下する尿滴を回収したり、環状体の上端面に、洗浄水を給水する環状体内通水路と、通水路に洗浄水を一定量又は一定時間送水して給水口から給水させる送水手段とを組合わせて縁洗浄型とすることによってボール部周壁上端面を洗浄して、受面部全面と合わせて水洗小便器から洗浄不能領域を無くすことが可能となる。また、受面部からボール部上空に突き出す使用者過剰接近防止具を設けたことは、縁洗浄型としたため洗浄水で濡れているボール部上端面に使用者衣服が接触することを防止することとなり、ボール部上端面とそれに続く外周面を多孔質体で形成し、内部から洗浄水を滲出させ、外周面を洗浄させて収水路で回収した後残留滲出水を吸引排することはボール部上端面の乾燥を速めて、濡れによる使用者の不安をなくす効果がある。 On the other hand, in the flush toilet prepared by separating the receiving surface part from the ball part and being combined with each other when attached to the toilet mounting position, in the top view, the outer peripheral part is substantially the same shape as the ball part outer peripheral part The annular body is arranged with a gap between the upper end surface of the ball part, and the outer peripheral wall surface following the upper end surface of the annular body is drawn inward from the outer peripheral wall surface of the ball part below the upper end face, A gap that does not hinder the flow of urine droplets flowing down the outer peripheral wall surface from the upper end surface of the annular body (hereinafter referred to as the water collecting channel) is created between the upper end surface and the urine droplets that flow down on their own. An annular body water passage that supplies cleaning water to the upper end surface of the annular body, and a water supply means that supplies the cleaning water to the water passage for a certain amount or for a certain period of time to supply water from the water supply port are combined into an edge cleaning type. Wash the top edge of the ball peripheral wall. To, it is possible to eliminate the cleaning impossible region from washing the urinal in conjunction with the receiving face entirely. In addition, the provision of a user excessive access prevention tool that protrudes from the receiving surface to the top of the ball part prevents the user's clothing from coming into contact with the upper end surface of the ball part that is wet with cleaning water because of the edge cleaning type. The upper end surface of the ball part and the outer peripheral surface following the ball part are formed of a porous body, the washing water is leached from the inside, the outer peripheral surface is washed and collected in the water collecting channel, and then the residual exuded water is sucked and discharged on the ball part. It has the effect of accelerating the drying of the end face and eliminating the user's anxiety due to wetting.

本発明の目的を達成するための実施例１から実施例１２を図１から図２２に示し、各実施例について説明する。 Examples 1 to 12 for achieving the object of the present invention are shown in FIGS. 1 to 22, and each example will be described.

図１から図４に本発明による実施例１の水洗小便器として、略逆円錐形のボール部１０と、このボール部１０と同じ径を有する半円筒形の受面部２０とによる組合せを示し、両者は図1と2に見られるようにボール部上端と受面部下端に沿って分離した別体として用意される。そして両者は別個にトイレットルームの設置取付け壁面に搬送され、順次壁面に取付けられ、図3と4に見られるように、取付け位置において一体に、ボール部上端縁と受面部下端縁を接合して、組合わされる。接合されるボール部上端縁と受面部下端縁とは、使用者の排尿や洗浄水が受面部内周面からボール部内に流下する際に接合面に回りこまないように構成する。 1 to 4 show a combination of a bowl portion 10 having a substantially inverted conical shape and a semi-cylindrical receiving surface portion 20 having the same diameter as the ball portion 10 as a flush toilet of Example 1 according to the present invention, As shown in FIGS. 1 and 2, both are prepared as separate bodies separated along the upper end of the ball portion and the lower end of the receiving surface portion. The two are transported separately to the installation wall surface of the toilet room, and are sequentially attached to the wall surface. As shown in FIGS. 3 and 4, the ball portion upper edge and the receiving surface lower edge are joined together at the attachment position. , Combined. The ball part upper end edge and the receiving surface part lower end edge to be joined are configured so that the user's urine or washing water does not flow around the joining surface when flowing from the inner peripheral surface of the receiving surface part into the ball part.

ここではボール部１０として、底部に外部排水管と接続される排水口１１を有し、背部に後述する設置取付け用台座へのボール部取付け具１８を植設した略逆円錐形のものを、また、受面部２０として、ボール部と同じ径の半円筒形で背部に後述の台座への受面部取付け具２８を植設したものを示したが、これらボール部と受面部は代表的な同種同形状における組合せの例である。なお、図示の排水口１１はストレート形状であるが、当然トラップ構造のものであって構わない。そして、ボール部と受面部はそれぞれ単純な形状をもって分離して作成されるから、搬送性と作業性においてきわめて有利となる。ボール部取付け具１８と受面部取付け具２８のそれぞれは、例えばボルトナットのような固定締着と着脱自在の両用に機能する部材とすれば有利であり、着脱自在とすればボール部と受面部のいずれか一方あるいは両方の取り外し交換が容易となる。このことはまた、図示の同種同形状のボール部と受面部の組合せに限らず、異種同形状の組合せや、同種異形状、あるいは異種異形状の組合せを可能とし、水洗小便器の機能性と意匠性の面において組合せに選択の自由が生じることを意味する。以下に記載する幾つかの実施例では、機能性の面から選択可能な組合せ例を示す。 Here, the ball portion 10 has a drain port 11 connected to an external drain pipe at the bottom, and a substantially inverted conical shape in which a ball portion mounting tool 18 is installed on the back of the mounting mounting base described later. Further, as the receiving surface portion 20, a semi-cylindrical shape having the same diameter as that of the ball portion and a receiving surface portion mounting tool 28 to be mounted on a pedestal to be described later are implanted in the back portion. It is an example of the combination in the same shape. Although the illustrated drain port 11 has a straight shape, it may naturally have a trap structure. Since the ball portion and the receiving surface portion are separately formed with a simple shape, it is extremely advantageous in terms of transportability and workability. Each of the ball part mounting tool 18 and the receiving surface part mounting tool 28 is advantageous if it is a member that functions for both fixed fastening and detachment, such as a bolt and nut, for example. Either or both of them can be easily removed and replaced. This is not limited to the combination of the same-type and same-shaped ball portion and the receiving surface portion shown in the figure, but also enables the combination of different types of the same shape, the same type of different shape, or the combination of different types of different shapes, and the functionality of the flush toilet. This means that freedom of choice occurs in the combination in terms of design. In some embodiments described below, examples of combinations that can be selected in terms of functionality are shown.

図５から図７は本発明による実施例２の水洗小便器を示し、図５と図６にその分離状態を正面斜視図と側面図で、図７にその組合せ状態を側面図でそれぞれ示す。実施例２が実施例１と異なる点は、互いに分離して用意されたボール部１０と受面部２０の間に、上面より見て、外周部がボール部外周部と略同形状でボール部上端面との間に隙間を開けて別体として配置された環状体１２が挿入されること、換言すれば、ボール部１０が、ボール部周壁１３を含む本体と、本体とは別体で用意されて設置取付けの際にボール部と受面部の間に組合される環状体１２とよりなることである。環状体１２はボール部周壁１３の上端との間に下記の構成を形成してボール部周壁１３上端面の汚染防止具として機能する。 FIGS. 5 to 7 show a flush toilet of Example 2 according to the present invention. FIGS. 5 and 6 show the separated state in a front perspective view and a side view, and FIG. 7 shows the combined state in a side view. The difference between the second embodiment and the first embodiment is that the outer peripheral portion is substantially the same shape as the outer peripheral portion of the ball portion between the ball portion 10 and the receiving surface portion 20 prepared separately from each other and viewed from the upper surface. The annular body 12 arranged as a separate body with a gap between the end face is inserted, in other words, the ball part 10 is prepared separately from the main body including the ball part peripheral wall 13 and the main body. And the annular body 12 assembled between the ball portion and the receiving surface portion during installation and mounting. The annular body 12 forms the following configuration between the upper end of the ball portion peripheral wall 13 and functions as a contamination prevention tool for the upper end surface of the ball portion peripheral wall 13.

環状体１２は、例えば実施例５を示す図１０の断面図に見られるように、ボール部周壁１３の上端に接近して取付けた時、環状体１２の上端面に続く外周面を、隙間を置いて下方に位置させるボール部周壁１３の外周面より内方に引込ませ、環状体１２の上端面からその外周面に沿って流下する尿滴をボール部周壁１３と環状体１２の外周面との間の隙間で形成した収水路１６によってボール部内、又は図１１の断面図に見られるように、ボール部１０の内方に傾斜するボール部周壁１３の内側上端面上に導き収容する。図１０の断面図でも示す図５から図７の実施例２では、このような構成をもってボール部周壁１３の上端面を覆う環状体１２は、その上端面に続く外周面を内方下向きに引込ませて、同様に内方に傾斜するボール部周壁１３の内側上端面に対面させ、その間の隙間でなる収水路１６によって、環状体１２の上面から流れる尿滴はボール部周壁１３の上端面からその外周面、更には設置床面までを汚染させることなく、ボール部内に収容される。 For example, as shown in the cross-sectional view of FIG. 10 showing the fifth embodiment, the annular body 12 has a gap between the outer peripheral surface continuing from the upper end surface of the annular body 12 when the annular body 12 is attached close to the upper end of the ball portion peripheral wall 13. The urine droplets that are drawn inward from the outer peripheral surface of the ball peripheral wall 13 to be placed and placed downward, and flow down along the outer peripheral surface from the upper end surface of the annular body 12, and the outer peripheral surface of the ball peripheral wall 13 and the annular body 12 As shown in the sectional view of FIG. 11, the water collecting channel 16 formed by the gap between the ball portion and the ball portion is guided and accommodated on the inner upper end surface of the ball portion peripheral wall 13 inclined inward. In the second embodiment shown in FIGS. 5 to 7, which is also shown in the cross-sectional view of FIG. 10, the annular body 12 covering the upper end surface of the ball portion peripheral wall 13 with such a configuration pulls the outer peripheral surface following the upper end surface inward and downward. Similarly, urine droplets flowing from the upper surface of the annular body 12 from the upper end surface of the ball portion peripheral wall 13 are caused to face the inner upper end surface of the ball portion peripheral wall 13 inclined inward, and by the water collecting passage 16 formed by a gap therebetween. It is accommodated in the ball portion without contaminating the outer peripheral surface and even the installation floor surface.

環状体１２が備えうる機能は上記の無給水型縁洗浄に限らず、後述のいくつかの実施例に示すように他の機能を備えるものがあり、本発明の特徴としてのボール部と受面部の分離形成と取付け時接合ないし着脱自在な取付けの利点として、所望の機能を持つ環状体の選択組合せを可能とし、また、取付け後の交換をも可能とする。 The functions that the annular body 12 can have are not limited to the above-mentioned non-water-supply type edge cleaning, but there are other functions as shown in some embodiments described later. As an advantage of the separate formation and the attachment or detachable attachment at the time of attachment, it is possible to select and combine annular bodies having a desired function, and also to allow replacement after attachment.

なお、環状体１２としてボール部と受面部と同形状の円形のものを示したが、これに限定されるものではなく、ボール部周壁外周部の形状に一致させて、半円形、半楕円形、楕円形あるいはこれらを組合せた形状のいずれの環状形であってもよい。なお、図中の符号１８ａは環状体取付具を示し、実施例１において述べた取付け用台座への取付けに用いる。 In addition, although the circular part 12 showed the circular thing of the same shape as a ball | bowl part and a receiving surface part, it is not limited to this, It is made to correspond to the shape of a ball part peripheral wall outer peripheral part, and a semicircle and a semi-elliptical shape. It may be any annular shape having an elliptical shape or a combination thereof. In addition, the code | symbol 18a in a figure shows an annular body attachment tool, and is used for the attachment to the mounting base described in Example 1. FIG.

さらに、図７の組合せ状態において環状体１２の内方下端は、環状体１２の外周面とボール部周壁１３の上端部内周面との間に隙間を置くことによって収水路１６を形成するので、環状体全周に亘ってボール部周壁１３の内周面から離間しているが、受面部２０の側壁が環状体１２の上端面と接合する近傍においても、受面部２０の外周面に飛散尿滴の付着とその流下があり得る以上、離間構成は有効である。
尚、ここでは受面部２０と環状体１２を別体として構成したが、両者を一体として用意し、別体のボール部と組み合わせることも出来る。 Further, in the combined state of FIG. 7, the inner lower end of the annular body 12 forms a water collecting channel 16 by placing a gap between the outer peripheral surface of the annular body 12 and the inner peripheral surface of the upper end portion of the ball portion peripheral wall 13. Although it is separated from the inner peripheral surface of the ball portion peripheral wall 13 over the entire circumference of the annular body, urine scattered on the outer peripheral surface of the receiving surface portion 20 even in the vicinity where the side wall of the receiving surface portion 20 is joined to the upper end surface of the annular body 12. The separation configuration is effective as long as there is drop adhesion and flow down.
Here, the receiving surface portion 20 and the annular body 12 are configured as separate bodies, but both can be prepared as a single body and combined with separate ball sections.

図８は、本発明による水洗小便器の実施例３として、実施例２における環状体に選択的に持たせ得る機能の一つである給水型縁洗浄構成を備えた環状体１２を、これと対向して収水路１６を形成するボール部周壁１３の上端部とともに示す。この実施例３が実施例２と異なる点は、環状体１２が上端面内に通水路１４を備え、通水路１４は上端面に開口する溢水口１５を有することである。その他の構成は実施例２においてすでに述べたものと同じであるので、ここでは反復を避けるが、この給水型縁洗浄機能を持った環状体１２を実施例２の環状体として用いれば、飛散尿滴による環状体表面の汚染は積極的に洗浄されることとなる。 FIG. 8 shows, as a third embodiment of a flush toilet according to the present invention, an annular body 12 having a water supply type edge cleaning structure which is one of the functions that can be selectively given to the annular body in the second embodiment. It shows with the upper end part of the ball part surrounding wall 13 which forms the water collecting path 16 facing. The third embodiment is different from the second embodiment in that the annular body 12 includes a water passage 14 in the upper end surface, and the water passage 14 has an overflow port 15 that opens to the upper end surface. Since other configurations are the same as those already described in the second embodiment, repetition is avoided here. However, if the annular body 12 having the water supply type edge cleaning function is used as the annular body of the second embodiment, the scattered urine Contamination of the surface of the annular body due to the droplets is positively cleaned.

通水路１５は、例えば図示しない洗浄水供給手段に接続され、使用者の離間検知等から一定時間あるいは一定量の洗浄水の供給を受け、供給された洗浄水は溢水口１５から環状体上端面の外周面と内周面に溢水して水膜流となる。溢水口１５から外周面側に溢水した水膜流は外周面に沿って流下し、収水路１６に収容される。この間、環状体の上端面や外周面に付着した尿滴があれば水膜流に取り込まれ、洗浄されることとなる。内周面側への溢水による水膜流も同様に内周面に沿って流下しつつ、付着尿滴の洗浄を行って環状体１２の下端からボール部内に収容される。通水路１４は、例えば組合せ時に接合する受面部２０下端の中央付近に対応する部分で中断され、その一方の端部において洗浄水供給手段と接続される。また、溢水口１５は受面部２０下端と接合する部分において閉止するか、開口のままとして溢水が行われるようにするか、いずれとすることも可能である。また、環状体１２上端面への給水手段は図示の溢水口１５によるものに限定されず、環状体上端面に給水された洗浄水が水膜流を形成する手段であれば、他の構成であってよい。 The water flow path 15 is connected to, for example, a cleaning water supply means (not shown) and receives a supply of cleaning water for a certain time or a certain amount from the detection of the separation of the user, and the supplied cleaning water flows from the overflow port 15 to the upper end surface of the annular body. The outer peripheral surface and the inner peripheral surface of the water overflow and become a water film flow. The water film flow overflowing from the overflow port 15 toward the outer peripheral surface flows down along the outer peripheral surface and is accommodated in the water collecting channel 16. During this time, any urine droplets adhering to the upper end surface or the outer peripheral surface of the annular body are taken into the water film flow and washed. Similarly, the water film flow caused by the overflow to the inner peripheral surface side is also washed along the inner peripheral surface while the attached urine droplets are washed and stored in the ball portion from the lower end of the annular body 12. For example, the water passage 14 is interrupted at a portion corresponding to the vicinity of the center of the lower end of the receiving surface portion 20 to be joined at the time of combination, and is connected to the cleaning water supply means at one end portion thereof. Further, the overflow port 15 can be either closed at a portion where it joins the lower end of the receiving surface portion 20 or can be overflowed while being left open. Further, the means for supplying water to the upper end surface of the annular body 12 is not limited to that shown by the overflow port 15 shown in the figure, and any other configuration can be used as long as the cleaning water supplied to the upper end surface of the annular body forms a water film flow. It may be.

図９は、本発明による水洗小便器の実施例４として、実施例２における環状体が選択的に備えうる機能のうち、実施例３に示すものとは異なる型の給水型縁洗浄構成をなす環状体１２を、これと対向して収水路１６を形成するボール部周壁１３の上端部とともに部分拡大断面図で示す。この実施例４の環状体１２が実施例３と異なる点は、周壁３０の略全体を多孔質体で形成し、その内部を中空として通水路３１としていることである。多孔質体周壁３０でなる環状体１２の他の構成と収水路１６の構成は、前述の実施例２について述べた構成と実質的に同じであり、ここでの反復は避ける。 FIG. 9 shows a water supply urinal cleaning configuration of a type different from that shown in Example 3 among the functions that the annular body in Example 2 can selectively have as Example 4 of the flush toilet according to the present invention. The annular body 12 is shown in a partially enlarged cross-sectional view together with the upper end portion of the ball portion peripheral wall 13 that forms the water collecting channel 16 in opposition thereto. The annular body 12 of the fourth embodiment is different from the third embodiment in that substantially the entire peripheral wall 30 is formed of a porous body, and the inside is hollow to form a water passage 31. The other configuration of the annular body 12 formed of the porous body peripheral wall 30 and the configuration of the water collecting channel 16 are substantially the same as the configuration described in the above-described second embodiment, and the repetition here is avoided.

通水路３１は洗浄水供給手段と接続され、一定量又は一定時間の給水を受け、洗浄水を多孔質体周壁３０より透過させて環状体の上端面や内外周面に滲み出させる。環状体１２の上端面から外周面側に滲出した洗浄水は外周面を洗浄しつつ流下し、収水路１６に収容されてボール部１０内に導かれる。従って実施例３の給水型縁洗浄構成の場合と同様に、多孔質体による環状体１２はボール部周壁１３の上端面の尿滴による汚染を防止するように機能し、ボール部上端面や内外周壁ならびに便器設置床面の汚染を防止する。なお、所望により、洗浄水滲出のための給水後に一旦空にした通水路内に陰圧を掛けて外周面に残留する滲出水を吸入し排水する手段を付加することもできる。 The water passage 31 is connected to the cleaning water supply means, receives a certain amount of water for a certain time, allows the cleaning water to permeate through the porous body peripheral wall 30 and oozes out from the upper end surface and the inner and outer peripheral surfaces of the annular body. The washing water that has oozed from the upper end surface of the annular body 12 to the outer circumferential surface flows down while washing the outer circumferential surface, is accommodated in the water collecting channel 16, and is guided into the ball portion 10. Accordingly, as in the case of the water supply type edge cleaning configuration of the third embodiment, the annular body 12 made of a porous body functions to prevent contamination by urine droplets on the upper end surface of the ball portion peripheral wall 13, and Prevent contamination of the surrounding wall and the toilet floor. If desired, a means for sucking and draining the exudate remaining on the outer peripheral surface by applying a negative pressure to the water passage that is once emptied after the water supply for the washing water exudation can be added.

図１０は、本発明による水洗小便器の実施例５であり、実施例２において環状体が選択的に備えうる機能の一例として既に述べた無給水型縁洗浄構成を持つ環状体１２を、これと対向して収水路１６を形成するボール部１３とともに部分拡大断面図で示す。この構成と機能の詳細は実施例２について既に述べたので、反復は避ける。 FIG. 10 is a fifth embodiment of the flush toilet according to the present invention. The annular body 12 having the non-water supply type edge cleaning configuration already described as an example of the function that the annular body can selectively include in the second embodiment is shown in FIG. And a ball portion 13 that forms a water collecting channel 16 in opposition to FIG. Details of this configuration and function have already been described for Example 2, so repetition is avoided.

図１１は、本発明による水洗小便器の実施例６として、実施例２の環状体が選択的に採り得る無給水型縁洗浄構成の変更形態における環状体１２を、これに対向して収水路１６を形成する変更形態のボール部周壁１３とともに部分拡大断面図で示す。変更形態の環状体１２は円形管でなるが、これは、円形管が、実施例５における曲面板状の環状体の上端部分と同様に、円形管の断面において最上端から最下端までの外側周面が緩やかな曲率で連続する曲面でなるため、例えば最上端に付着して外周面側に流下した尿滴はその表面張力により外周面に沿って最下端まで流れるので、本発明に用いる環状体として十分機能するためである。最上端から最下端までの内側周面についても全く同じ現象が見られ、両側周面を流下した尿滴はそれぞれ、また、時に合体して最下端からボール部内に収容される。 FIG. 11 shows a water collecting channel opposite to an annular body 12 in a modified form of a non-water supply type edge cleaning configuration that can be selectively adopted by the annular body of the second embodiment as a flush toilet according to the sixth embodiment of the present invention. 16 is shown in a partially enlarged cross-sectional view together with a ball portion peripheral wall 13 of a modified form forming 16. The annular body 12 of the modified form is a circular tube, which is the outer side from the uppermost end to the lowermost end in the cross section of the circular tube, like the upper end portion of the curved plate-shaped annular body in the fifth embodiment. Since the peripheral surface is a continuous curved surface with a gentle curvature, for example, urine droplets that adhere to the uppermost end and flow down to the outer peripheral surface side flow to the lowermost end along the outer peripheral surface due to the surface tension. This is because it functions sufficiently as a body. The same phenomenon is also observed on the inner peripheral surface from the uppermost end to the lowermost end, and the urine droplets flowing down the peripheral surfaces on both sides are sometimes combined and stored in the ball portion from the lowermost end.

一方円形管でなる環状体１２の下方にあって収水路１６の隙間を形成するボール部周壁１３は、やや肉厚とした上端面を略直線的に内方に下降する傾斜面とし、この傾斜面をもって環状体１２の最下端に対面する。したがって円形管の環状体１２の最下端から落下する尿滴は、ボール部周壁１３の内方傾斜面で捉えられ、確実にボール部１０内に導かれる。 On the other hand, the ball portion peripheral wall 13 below the annular body 12 made of a circular tube and forming the gap of the water collecting passage 16 has a slightly thick upper end surface as an inclined surface that descends inward substantially linearly. The face faces the lowermost end of the annular body 12. Therefore, the urine drop falling from the lowermost end of the annular body 12 of the circular tube is caught by the inwardly inclined surface of the ball portion peripheral wall 13 and is surely guided into the ball portion 10.

なお、本実施例６において環状体１２を中空円形管でなるものとし、これを無給水型縁洗浄構成としているが、これに限定することなく、中空部を通水路として利用し、溢水口あるいは同等に機能する水流出手段を設ければ、給水型縁洗浄構成とすることも可能である。また、中空円形管を多孔質材でなるものとした環状体１２を給水手段に接続すれば、実施例４と同様に機能する滲出水による給水型縁洗浄構成が得られる。 In the sixth embodiment, the annular body 12 is formed of a hollow circular tube and has a waterless edge cleaning structure. However, the present invention is not limited to this, and the hollow portion is used as a water passage, Provided with water outflow means that function in the same way, it is possible to adopt a water supply type edge cleaning configuration. Moreover, if the annular body 12 in which the hollow circular tube is made of a porous material is connected to the water supply means, a water supply type edge cleaning configuration with exudate that functions in the same manner as in Example 4 can be obtained.

図１２は、本発明による水洗小便器の実施例７として、実施例６における環状体１２と同じ円形管を用い、これを例えば実施例５に用いる薄厚のボール部周壁１３と組合わせてなる無給水型縁洗浄構成を示す。この構成において重要な点は、環状体１２を成す円形管の最下端が、ボール部周壁１３の内周面側に位置することであり、それによって、環状体１２の最下端から落下した尿滴が確実にボール部周壁１３内に回収されることである。因みに、実施例６について述べた給水型縁洗浄構成への適応性は、そのままこの実施例７にも適用される。なお当然であるが、円形管の最外周部を下方のボール部外周面と併せ、外径を変えることで、円形管の最下端の位置は任意に変えられる。 FIG. 12 shows a seventh embodiment of the flush urinal according to the present invention, in which the same circular tube as the annular body 12 in the sixth embodiment is used, and this is combined with the thin ball portion peripheral wall 13 used in the fifth embodiment, for example. A water supply type edge cleaning configuration is shown. The important point in this configuration is that the lowermost end of the circular tube forming the annular body 12 is located on the inner peripheral surface side of the ball portion peripheral wall 13, whereby the urine drop dropped from the lowermost end of the annular body 12. Is reliably collected in the peripheral wall 13 of the ball portion. Incidentally, the adaptability to the water supply type edge cleaning configuration described in the sixth embodiment is also applied to the seventh embodiment as it is. As a matter of course, the position of the lowermost end of the circular tube can be arbitrarily changed by changing the outer diameter of the circular tube together with the outer peripheral surface of the lower ball portion.

図１３から図１５は、本発明による水洗小便器の実施例８を示し、水洗小便器は実施例１に比して異種のボール部１０を同形の受面部２０と、図１３のように分離して用意し、図１４のように設置取付け時に組合わせてなる。ボール部１０は、図１３において断面で示すように、便器の正面側から背面部手前に掛けて、その上端部１２ａの上端面に続く外周壁を、上端面と略平行な位置で内方向に引込ませ、斜め下方に向けボール部周壁１３を横断してボール部内面で開口する隙間を備え、この隙間を、上端面から外周面に沿って流下する尿滴や水滴を含む液体の収容とボール部内への導入のための収水路１６として作用させる。他方、上端面から内周面に沿って流下する液体は、収水路１６の内方端縁から落下してボール部内に収容される。 13 to 15 show an eighth embodiment of the flush urinal according to the present invention. In the flush urinal, different ball parts 10 are separated from the receiving surface 20 having the same shape as in the first embodiment as shown in FIG. As shown in FIG. 14, it is combined at the time of installation and installation. As shown in a cross section in FIG. 13, the ball portion 10 is hung from the front side of the toilet in front of the rear portion, and the outer peripheral wall that continues to the upper end surface of the upper end portion 12a is directed inward at a position substantially parallel to the upper end surface. It is drawn and provided with a gap that opens diagonally downward across the ball portion peripheral wall 13 and opens on the inner surface of the ball portion. The gap contains the urine droplets and water droplets that flow down from the upper end surface along the outer peripheral surface. It acts as a water collecting channel 16 for introduction into the section. On the other hand, the liquid flowing down from the upper end surface along the inner peripheral surface falls from the inner end edge of the water collecting channel 16 and is stored in the ball portion.

図示はしないが、実施例１および２を含めて、受面部２０の上端部の略全長に亘って内周面側に洗浄水を給水する受面部給水手段を設け、受面部２０の内周面の略全域に洗浄水を水膜流として供給し、受面部内周面を洗浄させてボール部に収容し、排水させる。受面部給水手段は、例えば実施例３として図８に示した環状体１２の縁洗浄構成における通水路１４と溢水口１５を、溢水口の向きを内周面側に変更して応用することができる。 Although not shown, including the first and second embodiments, the receiving surface portion water supply means for supplying cleaning water is provided on the inner peripheral surface side over the substantially entire length of the upper end portion of the receiving surface portion 20, and the inner peripheral surface of the receiving surface portion 20 is provided. The cleaning water is supplied as a water film flow to substantially the entire area of the substrate, and the inner peripheral surface of the receiving surface portion is cleaned, accommodated in the ball portion, and drained. The receiving surface water supply means can be applied, for example, by changing the direction of the overflow port to the inner peripheral surface side in the edge cleaning configuration of the annular body 12 shown in FIG. it can.

本実施例８におけるボール部１０は、上記のように無給水型縁洗浄構成の上端部１２ａ
を持つものとしたが、所望によりこれを給水型縁洗浄構成の上端部を持つものとすることもできる。その場合は実施例３の図８に示す環状体１２のように、上端部１２の上端面内に通水路１４を設け、上端に溢水口１５を設けて給水手段に接続し、洗浄水を、例えば使用者の離間を検出してから一定量又は一定時間給水する。上記の受面部給水手段もこれに連動して動作する。溢水口１５から外周面側に出た溢水は外周面に沿ってこれを洗浄しつつ流下し、収水路１６を経てボール部１０内に収容される。溢水口１５から内周面側に出た溢水は内周面に沿ってこれを洗浄しつつ流下し、上端部１２ａの内方端縁からボール部１０内に落下し収容される。 As described above, the ball portion 10 according to the eighth embodiment has an upper end portion 12a having a waterless edge cleaning configuration.
However, it can also have the upper end of a water supply type edge cleaning arrangement if desired. In that case, like the annular body 12 shown in FIG. 8 of Example 3, the water flow path 14 is provided in the upper end surface of the upper end portion 12, the overflow port 15 is provided at the upper end, and connected to the water supply means. For example, water is supplied for a certain amount or for a certain time after detecting the separation of the user. The receiving surface water supply means also operates in conjunction with this. The overflow from the overflow port 15 toward the outer peripheral surface flows down along the outer peripheral surface while being washed, and is accommodated in the ball portion 10 through the water collecting passage 16. The overflow from the overflow port 15 toward the inner peripheral surface flows down along the inner peripheral surface while washing it, and falls into the ball portion 10 from the inner edge of the upper end portion 12a and is accommodated.

図１６および図１７は、本発明による水洗小便器の実施例９として、実施例２に示した逆円錐形のボール部１０とそのボール部周壁１３の上端を覆う形状の環状体１２、およびボール部の円形とは異なる略放物線形状の断面をもつ受面部２０の組合せでなるものを、設置取付け用の台座３４に取付けた状態で示す。これらボール部１０、環状体１２および受面部２０はもちろん互いに別体で分離して作成、用意され、設置場所に取付ける際に組合される。環状体１２は、実施例２において述べたように、実施例３から７にそれぞれ示す各種の機能ないし形態を持つものから選択される。 FIGS. 16 and 17 show, as a ninth embodiment of a flush toilet according to the present invention, an annular cone 12 having a shape covering the upper end of the inverted conical ball portion 10 and its peripheral wall 13 shown in the second embodiment, and a ball. A combination of the receiving surface portion 20 having a substantially parabolic cross section different from the circular shape of the portion is shown in a state of being attached to a mounting base 34. Of course, the ball part 10, the annular body 12 and the receiving surface part 20 are prepared and prepared separately from each other, and are combined when they are attached to the installation place. As described in the second embodiment, the annular body 12 is selected from those having various functions or forms shown in the third to seventh embodiments.

断面を略放物線形状とする受面部２０は、その両側端縁間の寸法を図１７の上面図に示すようにボール部１０の直径すなわち環状体１２の径より小さくしてあり、したがって組合せ状態において上面より見て、受面部２０はその全体をボール部１０内に位置させることとなり、下端縁のいずれの部分をもボール部ないし環状体１２の上端縁に接合させることはない。換言すれば、受面部の外周面はボール部の内周面の内側に位置するので、受面部の外周面に付着した尿滴、更には受面部外周面を流下する洗浄水すらもボール部内に収容されることとなる。このことは、受面部の内周面のみならず外周面全面、或いは少なくとも両側端縁に隣接する外周面部分に洗浄水を給水する受面部給水手段を、例えば実施例３の通水路と給水口構成により設けることを可能とし、環状体１２を縁洗浄構成とすることと相俟って、水洗小便器から非洗浄領域をなくすことを可能とする。これは、ボール部と受面部とを分離して用意することによる利点である。 As shown in the top view of FIG. 17, the receiving surface portion 20 having a substantially parabolic cross section has a dimension smaller than the diameter of the ball portion 10, that is, the diameter of the annular body 12, as shown in the top view of FIG. When viewed from above, the receiving surface portion 20 is entirely located in the ball portion 10, and any portion of the lower end edge is not joined to the upper end edge of the ball portion or the annular body 12. In other words, since the outer peripheral surface of the receiving surface portion is located inside the inner peripheral surface of the ball portion, urine droplets adhering to the outer peripheral surface of the receiving surface portion and even cleaning water flowing down the outer peripheral surface of the receiving surface portion are also in the ball portion. Will be housed. This means that the receiving surface portion water supply means for supplying cleaning water not only to the inner peripheral surface of the receiving surface portion but also to the entire outer peripheral surface or at least the outer peripheral surface portion adjacent to both side edges, for example, the water passage and the water supply port of the third embodiment It can be provided by the configuration, and it is possible to eliminate the non-cleaning region from the flush toilet together with the annular body 12 having the edge cleaning configuration. This is an advantage by separately preparing the ball portion and the receiving surface portion.

なお、図１７の上面図に見られるように、本実施例９の受面部２０はその両側端面において外側となる角部を削除し、内側の角部が鋭角をもって使用者に向くようにしたから、尿滴の飛散密度が高い領域にある両側端面の汚染が減少する。汚染が生じたとしても、外側の角部の削除により上記の受面部給水手段による外周面への給水が両側端面へ行き渡り易くなる。なお、受面部２０のボール部１０に対する高さ位置は、台座３４に対する受面部２０の取付け位置によって決まるから、受面部下端がボール部内に入る高さとボール部から上に出る高さの間で自由に設定できる。 Note that, as seen in the top view of FIG. 17, the receiving surface portion 20 of the ninth embodiment is such that the outer corners are removed on both side end surfaces so that the inner corners face the user with an acute angle. In addition, the contamination of both end surfaces in the region where the scattering density of urine droplets is high is reduced. Even if the contamination occurs, the water supply to the outer peripheral surface by the receiving surface water supply means becomes easy to spread to both end surfaces by deleting the outer corners. In addition, since the height position of the receiving surface portion 20 with respect to the ball portion 10 is determined by the mounting position of the receiving surface portion 20 with respect to the pedestal 34, it can be freely set between the height at which the lower end of the receiving surface portion enters the ball portion and the height at which the ball portion protrudes upward. Can be set.

図１８および図１９は、本発明による水洗小便器の実施例１０として、上面より見た形状を略三角形としたボール部１０と、上面より見て実施例９と同じくボール部内に位置する受面部２０でなるものを、図１８の分離状態と図１９の台座３４に取付け組み合わせた状態で示す。ボール部１０はボール部周壁１３上に環状体１２を備え、環状体１２はボール部１０ないし受面部２０の背面部に対応する部分を切り欠いた形状（ここではボール部の略三角形状に合わせて略Ｖ字形状だが、ボール部形状により略Ｃ字形状、略Ｕ字形状も含まれる）を有し、実施例３から７に示す各機能ないし形状を選択して備える。環状体１２の切り欠き部分は尿滴による汚染がなく、したがって洗浄を行わない受面部２０の背面部に対応し、この部分を切り欠くことによって軽量化も図れる。 18 and 19 show, as a tenth embodiment of a flush toilet according to the present invention, a ball portion 10 having a substantially triangular shape when viewed from the top surface, and a receiving surface portion located within the ball portion when viewed from the top surface as in the ninth embodiment. 20 is shown in a separated state in FIG. 18 and in a state of being combined with the pedestal 34 in FIG. The ball portion 10 includes an annular body 12 on the ball portion peripheral wall 13, and the annular body 12 has a shape in which a portion corresponding to the back surface portion of the ball portion 10 or the receiving surface portion 20 is cut out (here, it is matched with the substantially triangular shape of the ball portion). The shape is substantially V-shaped, but also includes a substantially C-shaped and a substantially U-shaped shape depending on the shape of the ball portion), and each function or shape shown in Examples 3 to 7 is selected and provided. The cutout portion of the annular body 12 is not contaminated by urine droplets, and therefore corresponds to the back surface portion of the receiving surface portion 20 that is not cleaned, and the weight can be reduced by cutting out this portion.

この実施例１０の特徴は受面部２０の形状にあり、内周面の中央上端に受面部給水手段として取付けた公知のスプレッダー３５を中心として、上端面から両側壁端面のすべてを含め、正面より見て、スプレッダー３５から撒水された水膜流の上縁の描く略放物線形状の曲線端面２５が形成される。スプレッダー３５からの水膜流は、したがって、受面部２０の内周面全域と曲線端面２５とに行き渡り、洗浄してボール部内に回収される。曲線端面２５を超えて受面部外周面に流れた水も、確実にボール部内に収容される。曲線端面２５の断面形状を例えば緩やかな楔型にしたり、スプレッダーの撒水量を制御したりすることによって、受面部側壁部分の外周面にも給水し、内周面と同時に洗浄可能となる。 The feature of the tenth embodiment is the shape of the receiving surface portion 20, centering on a known spreader 35 attached as a receiving surface portion water supply means to the central upper end of the inner peripheral surface, including all of the end surfaces of both side walls from the upper end surface. As seen, a substantially parabolic curved end face 25 drawn by the upper edge of the water film flow submerged from the spreader 35 is formed. Accordingly, the water film flow from the spreader 35 reaches the entire inner peripheral surface of the receiving surface portion 20 and the curved end surface 25, is washed, and is collected in the ball portion. Water that has flowed to the outer peripheral surface of the receiving surface beyond the curved end surface 25 is also reliably accommodated in the ball portion. By making the cross-sectional shape of the curved end face 25, for example, a gentle wedge shape or controlling the amount of water sprayed by the spreader, water is supplied also to the outer peripheral surface of the side wall portion of the receiving surface and can be cleaned simultaneously with the inner peripheral surface.

図２０は、本発明による水洗小便器の実施例１１として、実施例２で示した環状体付のボール部１０と、下端部の径をボール部径より小とするが上端部の径はボール部径より大とした受面部２０dとでなるものを組み合わせた状態の正面図で示す。ボール部上端の汚染に対する環状体１２については実施例３から７に記載した各種機能を選択的に採用し、上下端部の径の異なる受面部２０dの内外周面に対しても実施例８から１０に記載する洗浄構成が問題なく適用し得る。これは受面部表面材の濡れ特性により洗浄水や尿滴が表面材に密着して流下する性質によるものである。 FIG. 20 shows an embodiment 11 of the flush toilet according to the present invention, and the ball portion 10 with the annular body shown in the embodiment 2 and the diameter of the lower end portion is smaller than the diameter of the ball portion, but the diameter of the upper end portion is a ball. It shows with the front view of the state which combined what consists of the receiving surface part 20d made larger than a part diameter. Various functions described in the third to seventh embodiments are selectively employed for the annular body 12 with respect to contamination at the upper end of the ball portion, and the inner and outer peripheral surfaces of the receiving surface portion 20d having different diameters at the upper and lower ends are also from the eighth embodiment. 10 can be applied without problems. This is due to the property that washing water and urine droplets adhere to the surface material and flow down due to the wetting characteristics of the surface material of the receiving surface.

図２１および２２は、本発明による水洗小便器の実施例１２として、小便器への使用者の過剰接近を防止するために別体で用意される接近防止具２９を図２１の斜視図で、ボール部１０と組合わせた受面部２０の上端にこの接近防止具２９を載置した状態を図２２の上面図で、それぞれ示す。これは、例えば給水型縁洗浄構成とした実施例１０の水洗小便器において、使用者が上方より見て洗浄水で濡れているボール部１０の環状体１２が使用者の衣服、特にズボンに接触して汚すのではないか、という危惧を抱かせることへの対策である。そのため、受面部２０上端に載置した接近防止具２９はその両側端縁からボール部１０の上空に、環状体１２の外周をやや越えて突き出し、使用者がそれ以上接近することを阻止するアームを備える。この接近防止具２９はアームと逆方向に突き出して植設した防止具取付具２９ａによって、例えば図１６に示す台座３４に、ボール部１０および受面部２０とともに着脱自在に取付けられる。この実施例も、ボール部１０と受面部２０との分離作成と取付け時組合せ構成がもたらす利点である。 FIGS. 21 and 22 are perspective views of FIG. 21 showing an access prevention tool 29 prepared separately to prevent an excessive access of a user to a urinal as Example 12 of the flush urinal according to the present invention. The top view of FIG. 22 shows the state where this approach prevention tool 29 is placed on the upper end of the receiving surface portion 20 combined with the ball portion 10. This is because, for example, in the flush urinal according to the tenth embodiment having a water supply type edge cleaning configuration, the annular body 12 of the ball portion 10 wet with the cleaning water as viewed from above is in contact with the user's clothes, particularly the pants. It is a measure to raise the fear that it will be polluted. Therefore, the access prevention device 29 placed on the upper end of the receiving surface portion 20 protrudes from the both side edges of the ball portion 10 to slightly above the outer periphery of the annular body 12 to prevent the user from approaching further. Is provided. The access prevention tool 29 is detachably attached to the pedestal 34 shown in FIG. 16, for example, together with the ball part 10 and the receiving surface part 20 by means of a prevention tool attachment tool 29a that protrudes in the opposite direction to the arm. This embodiment is also an advantage brought about by the combined construction at the time of separating and mounting the ball portion 10 and the receiving surface portion 20.
