In this case, the soft packing material 6 with which the convex rib 3 contacts is provided in the same recess 5.

以下、この実施形態の洋式便器をより具体的詳細に説明する。この実施形態の洋式便器では、図２に示すように、便器本体１の排便用開口部７の開口縁全周に沿って中空状のリム部２が一体に形成されており、このリム部２内に流通されてここから吐出される水によって同排便用開口部７内は使用後に洗浄される。また、便器本体１は合成樹脂にて一体成形されたもので、排便用開口部７の前側略半分の略半円部分において、リム部２の前側上面２ａにその外周縁２ｂに沿って汚水流出防止用の凸リブ３が一体に立設されている。凸リブ３はリム部２の前側に立設されればよいものであるが、排便用開口部７の開口縁全周にわたって形成されてもよい。 Hereinafter, the western-style toilet of this embodiment will be described in more detail. In the western style toilet of this embodiment, as shown in FIG. 2, a hollow rim 2 is integrally formed along the entire periphery of the opening edge of the defecation opening 7 of the toilet body 1, and this rim 2 The inside of the stool opening 7 is washed after use by water that is circulated inside and discharged therefrom. Further, the toilet body 1 is integrally formed of synthetic resin, and the sewage flows along the outer peripheral edge 2b on the front upper surface 2a of the rim portion 2 at a substantially semicircular portion of the front half of the defecation opening 7. Protruding ribs 3 for prevention are erected integrally. The convex rib 3 may be provided on the front side of the rim portion 2, but may be formed over the entire periphery of the opening edge of the defecation opening 7.

便器本体１の後端部上には人体局部洗浄装置が内蔵設置され、この人体局部洗浄装置部位に便座４及び便蓋８が枢支されされている。便座４及び便蓋８は軸部９を中心に回動されるもので、便座４が便器本体１の排便用開口部７上に着脱自在に載置され、その上を覆う便蓋８は開閉される。便座４は暖房機能を有しており、その下面４ａに両側対に配置される脚部１０と前記便器本体１の凸リブ３と対応する位置に凹所５が形成されている。脚部１０はゴム等の弾性材でなり、その内部には人体が着座したことを検知する着座センサが設けられる。この着座センサの検知に基づいて、前記便座４の暖房機能や人体局部洗浄装置等が動作制御される。 A human body local cleaning device is built in and installed on the rear end of the toilet body 1, and a toilet seat 4 and a toilet lid 8 are pivotally supported by the human body local cleaning device. The toilet seat 4 and the toilet lid 8 are pivoted about the shaft portion 9, and the toilet seat 4 is detachably mounted on the defecation opening 7 of the toilet body 1, and the toilet lid 8 covering the toilet seat 4 is opened and closed. Is done. The toilet seat 4 has a heating function, and a recess 5 is formed on the lower surface 4a at a position corresponding to the leg portions 10 arranged on both sides and the convex rib 3 of the toilet body 1. The leg portion 10 is made of an elastic material such as rubber, and a seating sensor for detecting that a human body is seated is provided in the leg portion 10. Based on the detection of the seating sensor, the heating function of the toilet seat 4 and the local body washing device are controlled.

前記脚部１０が便器本体１のリム部２上に当接された状態で、図１に示すように、便座４は同リム部２上に載置支持されている。便器本体１及び便座４はいずれも合成樹脂でなり、所望の形状に成形され易いものである。便器本体１の排便用開口部７の開口縁内周には断面略矩形の中空状のリム部２が一体に形成されており、このリム部２の前側上面２ａは略水平な平坦面となっている。リム部２の前側上面２ａにはその外周縁２ｂに沿って凸リブ３が立設され、この凸リブ３は断面略三角形状の山型に突出しており、同凸リブ３とリム部２の前側上面２ａとの内側隅部分が曲面形状Ｒに形成されていて、この曲面形状Ｒの部分は清掃し易くて汚れやゴミ等が溜まり難い。 The toilet seat 4 is placed and supported on the rim portion 2 as shown in FIG. 1 in a state where the leg portion 10 is in contact with the rim portion 2 of the toilet body 1. The toilet body 1 and the toilet seat 4 are both made of synthetic resin and can be easily formed into a desired shape. A hollow rim 2 having a substantially rectangular cross section is integrally formed on the inner periphery of the opening edge of the defecation opening 7 of the toilet body 1, and the front upper surface 2 a of the rim 2 is a substantially horizontal flat surface. ing. A convex rib 3 is erected on the front upper surface 2a of the rim portion 2 along its outer peripheral edge 2b. The convex rib 3 protrudes in a mountain shape having a substantially triangular cross section. An inner corner portion with the front upper surface 2a is formed in a curved surface shape R, and the curved surface shape R portion is easy to clean and dirt and dust are not easily collected.

便座４の下面４ａと前記便器本体１のリム部２の前側上面２ａとは相互に略平行で、前記脚部１０の厚さ分だけの間隔をあけて対向している。便座４の下面４ａの外周に沿った部位には断面略三角形状で谷型の凹所５が形成されており、この凹所５内には前記凸リブ３が対応し隙間をあけて嵌合収容される。凹所５内の底部分には軟質合成樹脂、ゴム等でなり弾性及び防水性を有した軟質パッキン材６が設けられており、この軟質パッキン材６は前記凸リブ３の先端部分上に当接支持されて前記隙間を密閉する。その際、凹所５の前壁片部５ａの下端は凸リブ３の先端部分の上端よりも下方に位置しており、汚水の流出が確実に防止される。 The lower surface 4a of the toilet seat 4 and the front upper surface 2a of the rim portion 2 of the toilet body 1 are substantially parallel to each other and are opposed to each other with an interval corresponding to the thickness of the leg portion 10. A recess 5 having a substantially triangular cross section is formed in a portion along the outer periphery of the lower surface 4a of the toilet seat 4, and the convex rib 3 is fitted into the recess 5 with a gap therebetween. Be contained. A soft packing material 6 made of soft synthetic resin, rubber or the like and having elasticity and waterproof properties is provided at the bottom of the recess 5, and the soft packing material 6 is placed on the tip of the convex rib 3. Closely supported to seal the gap. At that time, the lower end of the front wall piece 5a of the recess 5 is positioned below the upper end of the tip portion of the convex rib 3, so that the outflow of sewage is reliably prevented.

したがって、この実施形態の洋式便器においては、便器本体１のリム部２の前側上面２ａにその外周縁に沿って汚水流出防止用の凸リブ３が立設されているので、同前側上面２ａに降りかかった汚水は凸リブ３で堰き止められて便器本体１の外側へ流出せず内側へと支障なく排水除去される。そのため、便座４を起立させた不使用の状態で男性が立って手前側から小便をした際等に、尿がリム部２の前側上面２ａに降りかかっても、この尿である汚水は同リム部２の前側上面２ａの外周縁２ｂから便器本体１の外側へ垂れ落ちることがない。 Therefore, in the western-style toilet of this embodiment, since the convex rib 3 for preventing a sewage outflow is standingly arranged along the outer periphery on the front upper surface 2a of the rim part 2 of the toilet body 1, the front upper surface 2a The sewage that has fallen is blocked by the convex ribs 3 and does not flow out of the toilet body 1 and is drained and removed to the inside without hindrance. Therefore, even when urine falls on the front upper surface 2a of the rim portion 2 when a man stands and urinates from the near side when the toilet seat 4 is not used upright, the urine sewage remains in the rim. The outer peripheral edge 2 b of the front upper surface 2 a of the part 2 does not sag to the outside of the toilet body 1.

しかも、前記凸リブ３が便器本体１のリム部２の前側上面２ａに一体に立設されているため、隙間は発生せず汚水の流出が確実に防止され、この部分は清掃し易くて汚れやゴミ等も付着し難い。また、便座４の下面４ａには前記凸リブ３が嵌合される凹所５が形成されているため、便座４をリム部２上に載置支持させた使用の状態で同凸リブ３と凹所５とが嵌合して、洗浄水や男性の小便等の汚水は便座４の下面４ａとリム部２の前側上面２ａとの間の隙間から便器本体１外へと流出し難い。 Moreover, since the convex rib 3 is erected integrally with the front upper surface 2a of the rim portion 2 of the toilet body 1, there is no gap and the outflow of sewage is surely prevented. It is hard for dust and dirt to adhere. Further, since the recess 5 into which the convex rib 3 is fitted is formed on the lower surface 4 a of the toilet seat 4, the convex rib 3 and the convex rib 3 can be used in a state where the toilet seat 4 is placed and supported on the rim portion 2. The recess 5 is fitted, so that sewage such as washing water and male urine is unlikely to flow out of the toilet body 1 from the gap between the lower surface 4 a of the toilet seat 4 and the front upper surface 2 a of the rim 2.

特に、この場合、凹所５内に凸リブ３が当接される軟質パッキン材６が設けられているので、この軟質パッキン材６によって同凹所５と凸リブ３との間の隙間は密閉され、汚水の便器本体１外への流出が確実に防止される。このように、尿や洗浄水等の汚水が便器本体１の外側へと流出することが確実に防止されることで、同便器本体１とトイレ床面との隙間に汚水が入り込むことによる雑菌の繁殖や悪臭の発生等の問題は解消され、トイレ内が衛生的に保持される。 In particular, in this case, since the soft packing material 6 with which the convex rib 3 abuts is provided in the recess 5, the gap between the recess 5 and the convex rib 3 is sealed by the soft packing material 6. Thus, outflow of sewage out of the toilet body 1 is reliably prevented. In this way, sewage such as urine and washing water is reliably prevented from flowing out of the toilet main body 1, so that germs caused by sewage entering the gap between the toilet main body 1 and the toilet floor surface can be prevented. Problems such as breeding and the generation of odors are eliminated and the toilet is kept hygienic.
