BEST MODE FOR CARRYING OUT THE INVENTION
本発明をより詳細に説述するために、 以下添付図囬'に従つ てこれを説明する。  In order to explain the present invention in more detail, this will be described below with reference to the attached drawing 囬 ′.
図中 （A) は便器本体で、 隔壁を介して相互に隣接するよ うに区画形成されたボール部 （ 1 ) ， 給水室 （2 ) ， トラ ッ プ排水路 （ 3) を備え、 トラ ップ排水路 （ 3) がボール部 ( 1 ) 底部と便器本体 （A) 後部底壁に開設した排便口 （ 7 ) とを大略 S字状に屈曲して連絡している。  In the figure, (A) is the toilet body, which is provided with a ball section (1), a water supply chamber (2), and a trap drainage channel (3) that are formed so as to be adjacent to each other via a partition wall. A drainage channel (3) connects the bottom of the bowl (1) and the toilet port (7), which is opened in the rear bottom wall of the toilet body (A), by bending it into an approximately S-shape.
ボール部 （ 1 ) には給水室 （ 2 ) に連絡する リ ム通水路 The ball section (1) has a rim waterway that connects to the water supply room (2).
(5) がボール部 （ 1 ) 上端終縁に沿って該部 （ 1 ) 内方に 突出するように環状に形成されており、 またリ ム通水路 （5 ) には底面にリ ム水出孔 （4) を適宜間隔毎に開設してある。 (5) is formed in an annular shape so as to protrude inward along the ball portion (1) along the end edge of the upper end. Holes (4) are opened at appropriate intervals.
また、 便器本体 （A) にはボール部 （ 1 ) の最後部に汚物 落し込み凹部 （ 6) が形成されており、 該汚物落し込み凹部 Further, the toilet body (A) is provided with a dirt dropping recess (6) at the rear end of the ball portion (1).
(6) の後側面部に前記 トラ ップ排水路 （3 ) の入口 (31) が開口されている。 The entrance (31) of the trap drainage channel (3) is open at the rear side of (6).
以上の構造形態はサイ.ホン式水洗便器と して従来周知のも のであり、 本発明はこの従来周知の構造形態を有するサイホ ン式水洗便器において、 ボール部 （ 1 ) がその後側底部のボ ール面 （ 1 ' ) の形状を断面略 V字型の窪み状に形成される。  The above-mentioned structure is conventionally known as a siphon-type flush toilet, and the present invention relates to a siphon-type flush toilet having a conventionally well-known structure, wherein a ball portion (1) has a bottom bottom portion. The shape of the roller surface (1 ') is formed in a concave shape with a substantially V-shaped cross section.
即ち、 上記ボール面 （ 1 ' ) の断面略 V字型の窪み部分 (a) は、 ボール部 （ 1) の中央付近からボール部後壁 （11) に至る部分に後方へ向かつて拡開するように形成し、 汚物落 し込み凹部 （ 6 ) を囲んで該凹部 （ 6 ) に落ち込み状に連絡 せしめる。 That is, the concave portion (a) having a substantially V-shaped cross section of the ball surface (1 ') extends from near the center of the ball portion (1) to the rear wall (11) of the ball portion. Is formed so as to extend rearward toward the portion reaching the bottom, and surrounds the dirt dropping recess (6) and is connected to the recess (6) in a dropping manner.
従って、 この断面略 V字型の窪み部分 （ a ) はリ ム通水路 (5 ) のリ ム水出孔 （4 ) から射水されてボール面 （ 1 ' ) を流下する洗浄水の各支流を該部分 （ a ) に集中させ 1本の 太い流れと して汚物落し込み凹部 （ 6 ) に流し込むことがで さ な 。  Therefore, the concave portion (a) having a substantially V-shaped cross section is used to supply each of the tributaries of the washing water which is sprayed from the rim water outlet (4) of the rim water passage (5) and flows down the ball surface (1 '). It is not possible to concentrate on the portion (a) and to flow into the dirt drop recess (6) as one thick flow.
尚、 ボール面 （ 1 ' ) の上記断面略 V字型の窪み部分 （ a ) 以外の部分は従来の便器同様大きな曲率の曲面に形成されて 上記窪み部分 （ a ) に連絡するが図示例ではこの部分は異な る曲率の複数の適当な曲面の連続により形成されており、 後 壁側を除き溜水面 （b ) 位置に相当する部位の若干 h方から 若干下方にかけての適宜幅部分を、 それより上方及び下方の 部分より曲率の小さな曲面に形成することにより、 該部を外 方へ若干膨らむような形状の段部 （ 8 ) に形成している。  The portion of the ball surface (1 ') other than the concave portion (a) having a substantially V-shaped cross section is formed into a curved surface having a large curvature like the conventional toilet bowl, and is connected to the concave portion (a). This part is formed by the continuation of a plurality of appropriate curved surfaces with different curvatures. Except for the rear wall side, an appropriate width part slightly below the part corresponding to the location of the water reservoir surface (b) and slightly below it, By forming a curved surface having a smaller curvature than the upper and lower portions, the portion is formed as a stepped portion (8) that slightly expands outward.
これにより、 溜水面位置に相当す 部位のボール面 （ 1， ） が段部 （ 8 ) により外方へ膨らんで広く なるので、 少ない溜 水量となしても溜水面を大き く とることが可能となる。  As a result, the ball surface (1,) at a portion corresponding to the water surface level bulges outward and wide due to the step (8), so that the water surface can be enlarged even if the water volume is small. Become.
このことはボール面 （ 1， ） への汚物の付着が少なく衛生 的で洗浄， 排出時の トータル水量も少ない便器を提供できる ことを意味する。 一方、 リ ム通水路 （5) の リ ム水出孔 （4) は、 リ ム通水 路 （ 5 ) 全周に亘つて設けられるが、 最前部即ち所謂リ ップ 側に設ける数個例えば 5個の孔径を特別大孔径、 具体的には 一般的な便器における該部のリ ム水出孔 （4) の径が U0程 度であるのに対して 20 (6に形成し、 洗浄水に勢をつけるよう になっている。 This means that it is possible to provide a toilet bowl that has less sanitary deposits on the ball surface (1,) and that is hygienic and has a smaller total water volume during washing and discharging. On the other hand, the rim water outlet (4) of the rim water channel (5) is provided over the entire circumference of the rim water channel (5). The five holes have special large diameters, specifically 20 (6) while the rim water outlet (4) of the general toilet bowl has a diameter of about U0. It is set to gain momentum.
これにより、 水の勢をつけるために洗浄水タ ンク （B) 内 のへッ ドを上げる必要がなく なり、 夕 ンク容量が少なくてす むようになる。  As a result, it is not necessary to raise the head in the washing water tank (B) in order to urge the water, so that the evening tank capacity is reduced.
従って以上説明した斯る構造により本発明は所期の目的を 十分に達成し、 大幅な節水を計るこ とができるが、 図示例に おいては、 一層の節水を計るため更に下記するような構造を 備えている。  Therefore, the present invention sufficiently achieves the intended purpose and can greatly save water by the above-described structure.However, in the illustrated example, the following is further described in order to further save water. It has a structure.
即ち、 上記大孔径に形成したリ ム水出孔 （4) は、 第 2図 に示すようにリ ム通水路 （5) 底壁を出孔 （4) 孔縁に沿つ て内方又は外方へ突出 （41) せしめたり、 第 5図に示すよう にリ ム水出孔 （4) に筒状部材 （42) を装着してその射水ガ ィ ド面をリ ム通水路 （5) 底壁の肉厚方向に伸長させてある c これにより洗浄水支流はばらつきの少ないまつすぐな流れに なるようにガイ ドされるをもって洗浄水支流の結束力が強く なり、 リ ム通水路 （5) の最前部側から トラ ップ排水路入口 (31) へ向けて勢いよく まつすぐに流れる主流が形成され、 前記断面略 V字型の窪み部分による洗浄水の結束と相俟って 本発明の効果を一層大ならしめることができる。 That is, as shown in Fig. 2, the rim water outlet (4) formed with the large hole diameter has a rim water passage (5) a bottom wall and an inner hole or an outer hole (4) along the hole edge. (41), or as shown in Fig. 5, a cylindrical member (42) is attached to the rim water outlet (4) and the spray guide surface is fitted to the rim water channel (5) bottom. Extending in the direction of the wall thickness c This guides the cleaning water tributary to a straight flow with little variation and increases the binding power of the cleaning water tributary, and the rim water channel (5) From the front side of the trap water drainage channel entrance (31) The effect of the present invention can be further enhanced in combination with the binding of the washing water by the concave portion having a substantially V-shaped cross section.
また、 リム通水路 （5) はその底面部を後方に向けて下向 きに傾斜せしめて形成し、 リ ム通水路 （5) 後部からの射水 を長引かせることにより、 水封用の補給水を確保するように している。  In addition, the rim water channel (5) is formed with the bottom part inclined downward and rearward, and the water supply from the rear of the rim water channel (5) is prolonged, so that the water supply for water sealing can be achieved. To ensure that
これにより、 溜水面 （b) を上昇回復させるために一定量 以上の洗浄水を供給する必要のない、 節水性により侵れた水 洗式便器を提供できる。 また同時に、 タ ンク （B) 内給水金 具に複雑な捕給水供給機構を備えることが不要となるばかり でなく、 前記給水金具の給水圧変動に影響されることなく常 に一定高さの溜水面 （b) を得ることができる。  This makes it possible to provide a flush toilet that is affected by water saving and does not need to supply a certain amount or more of flush water to raise and recover the water level (b). At the same time, it is not only unnecessary to equip the tank (B) with a complicated catching water supply mechanism in the water supply fitting, but also to constantly maintain a constant height without being affected by the water supply pressure fluctuation of the water supply fitting. Water surface (b) can be obtained.
トラップ排水路 （3) は、 その下降路 （Π) の中途部にお ける便器本体 （A) 後壁側に段設面 （9) が形成され、 さ ら に下降路 （32) における前記段設面の下流側 （32a)を、 段設 面 （9) の突出量だけ上昇路 （33) 方向へ偏芯させてある。  The trap drainage channel (3) has a stepped surface (9) formed on the rear wall side of the toilet body (A) in the middle of the descending channel (Π), and further has a step surface in the descending channel (32). The downstream side (32a) of the installation surface is eccentric in the direction of the rising path (33) by the amount of protrusion of the step surface (9).
段設面 （9) は第 1図に示す如く、 下降路 （32) の内周に 沿い約半周程度に亘つて平面三ヶ月状に突設され、 沈-浄水の 流下方向に対して大略直角に突出している。  As shown in Fig. 1, the step surface (9) protrudes in a three-month plane along the inner circumference of the descending path (32) for about half a circumference, and is approximately perpendicular to the flowing direction of the settling water. It protrudes.
トラ ップ排水路 （3) の斯る構造は、 排水路 （3) 内に流 入しその下降路 （Π) 内を流下する洗浄水を段設面 （9) に 衝突させた後下流側に偏芯した状態で流下させることになり、 トラ ップ排水路 （3 ) における段設面の上流側をより確実に 満水させることができ、 よって少量の給水でサイホン作用を 早く起してボール部内の汚物を一気に流出させる。 The trap drainage channel (3) has such a structure that the washing water flowing into the drainage channel (3) and flowing down the descending channel (Π) collides with the stepped surface (9) and then downstream. Will flow down in an eccentric state, The upstream side of the step surface in the trap drainage channel (3) can be more reliably filled with water. Therefore, a small amount of water is supplied to quickly cause a siphon action, thereby allowing the dirt in the ball portion to flow out at once.
即ち、 節水性を一層向上させ得る。 '  That is, water saving can be further improved. '
