摘要:
Problem: To provide a flush toilet capable of effectively expelling waste using a swirl flow without utilizing a strong siphon action. Solution Means: The present invention is a flush toilet (1), comprising a bowl portion (2) having a bowl-shaped waste-receiving surface and a rim portion, the inside wall surface on the top edge of which protrudes inward; a trap pipe (4) connected to the bottom portion of the bowl portion to expel waste within the bowl portion; a first shelf portion (6) formed to follow the rim portion; a second shelf portion (8) formed on the waste-receiving surface below the first shelf portion and above an initial accumulated water level; a first orifice (10) for issuing water onto the first shelf portion and forming a swirl flow on the waste-receiving surface; a second orifice (12) for issuing water onto the second shelf portion and forming a flow to stir flush water within the bowl portion; and first and second flow paths (14, 16) for respectively supplying flush water to the first and second orifices.
