Abstract (en)
[origin: EP4083340A1] The problem to be overcome by the present disclosure is to propose a flush toilet designed to reduce the splash of water in a backflow check structure. A flush toilet includes: a bowl; a water discharge port to discharge water into the bowl; a water supply path (3) to supply the water from a water supply source to the water discharge port; and a backflow check structure (4) to check a backflow of the water running through the water supply path (3). The backflow check structure (4) has: a water inlet port (410) communicating with the water discharge port; a water receiving wall (5), through which the water inlet port (410) is provided in a part thereof; and a water outlet port (400) spaced from the water inlet port (410) and the water receiving wall (5) and configured to channel the water supplied from the water supply source toward the water inlet port (410). The water receiving wall (5) is provided, in a part thereof below the water inlet port (410), with a water adhesion reducing portion (9) to reduce the chances of the water adhering to a lower end surface (520) of the water receiving wall (5).
