FLUSH TOILET BOWL
To provide a flush toilet bowl that can both save water and have washability of the bowl portion.SOLUTION: A flush toilet bowl 1 according to an embodiment of the present invention includes a water supply device 4 that continuously supplies a constant large flow rate of cleaning water to a toilet bowl body for a predetermined time, a bowl portion 8 having a bowl-shaped waste receiving surface 16 and a rim portion 18 located on the upper edge and having the inner peripheral surface, and a first rim water discharge port 24 that discharges the cleaning water supplied from the water supply device in an almost horizontal direction along the inner surface of the rim portion to form a swirling flow. The rim portion is formed in an overhang shape, and the overhang shape of the inner surface forms a channel for the cleaning water. The bowl portion is formed so that the cross-sectional area D2 of the cross-section enclosed by a straight line L1 lowered vertically from the innermost peripheral end of the rim portion in the area of the front end having the smallest radius of curvature R1 in the plan view of the bowl portion and the inner surface of the bowl portion located outside of this straight line is larger than the cross-sectional area D1 of the first rim water discharge port 24.SELECTED DRAWING: Figure 2
【課題】節水化とボウル部の洗浄性を両立させることが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1は、一定の大流量の洗浄水を所定時間継続して便器本体へ供給する給水装置4と、ボウル形状の汚物受け面16と、上縁に位置し内周面を有するリム部18と、を備えたボウル部8と、給水装置から供給された洗浄水をリム部の内周面に沿ってほぼ水平方向に吐水し旋回流を形成する第1リム吐水口24と、を有し、リム部は、オーバーハング形状に形成され、この内周面のオーバーハング形状により洗浄水の通水路が形成され、ボウル部の平面視で最小の曲率半径R1の前端の領域においてリム部の最内周端から鉛直方向下方に下ろした直線L1と、この直線より外側に位置するボウル部の内周面とにより取り囲まれる断面の断面積D2が、第1リム吐水口24の断面積D1よりも大きくなるように、ボウル部が形成されている。【選択図】図2
