<p>PROBLEM TO BE SOLVED: To provide a water closet device which is configured to supply wash water at a large flow rate to a rim part by utilizing a jet pump action, and prevents overflow of water from the rim part.SOLUTION: A water closet device FT is configured to execute: a first step of feeding water at a first flow rate to water discharge parts 133, 135; a second step of feeding water at a second flow rate smaller than the first flow rate to the water discharge parts 133, 135; and a third step of feeding water at a third flow rate larger than the second flow rate to the water discharge parts 133, 135; in a process in which water is fed from a tank 20 to the water discharge parts 133, 135 by a jet pump and thus a water level in the tank 20 is lowered from a full water level to the position of a suction port. A flow pass state of a jet pump unit is switched so that a jet pump action in the second step is suppressed more than the first step as well as the third step.</p> |
