<p>PROBLEM TO BE SOLVED: To provide a water closet device which supplies wash water by jet pump action to a rim part, ensures a high washing performance, and prevents overflow of water from the rim part.SOLUTION: In a process in which water is supplied from a tank to water discharge part by a jet pump unit 300 and a water level in the tank lowers from a full water level to the position of a suction port 321, a first step for supplying a first flow rate water to the water discharge part and a second step for supplying a second flow rate water smaller than the first flow rate water to the water discharge part are executed. A water closet device includes: a feed water pipe 231 for feeding water to a nozzle 310; a water discharge part 401 in the tank for discharging a part of water flowing in the feed water pipe into the tank; and flow pass state switching means 400 for switching the flow pass state of the feed water pipe so that a part of water flowing in the feed water pipe is discharged into the tank by the water discharge part in the tank. The flow pass state switching means is configured so that the flow rate of water discharged from the water discharge part in the tank in the second step is larger than the flow rate of water discharged from the water discharge part in the tank in the first step.</p> |
