WATER CLOSET
To provide a water closet capable of suppressing occurrence of flow pressure loss due to separation of a flow flowing from a bent part to an inner part.SOLUTION: A water closet of the present invention comprises: a rim water passage 46 that is formed in a rim part on one of the right or left side of a bowl part so as to make washing water supplied from a washing water source pass through the bowl part; and a rim water discharge port 48 that is formed at a downstream end of the rim water passage and discharges the washing water backward. The rim water passage comprises: an outside part 56 that extends forward from an inlet part through the interior of the rim part; a bent part 58 that bends inward from a downstream end part of the outside part; and an inside part 60 that extends rearward from the bent part to the rim water discharge port. The bent part comprises a flow channel cross-sectional area expansion part 62 that enlarges a flow channel cross-sectional area of the bent part.SELECTED DRAWING: Figure 5
【課題】屈曲部から内側部に流入する流れの剥離による流れの圧力損失が生じることを抑制できる水洗大便器を提供する。【解決手段】本発明の水洗大便器は、洗浄水源から供給される洗浄水をボウル部内に通水するように、ボウル部の左右の何れか一方の側のリム部内に形成されたリム通水路４６と、リム通水路の下流端に形成されると共に洗浄水を後方に向けて吐水するリム吐水口部４８と、を備え、リム通水路は、入口部からリム部の内部を前方に向けて延びる外側部５６と、外側部の下流端部から内側に屈曲する屈曲部５８と、屈曲部から後方に向かってリム吐水口部まで延びる内側部６０とを備え、屈曲部は、屈曲部の流路断面積を拡大する流路断面積拡大部６２を備える。【選択図】図５
