<p>PROBLEM TO BE SOLVED: To provide a water closet device that can prevent a phenomenon in which water overflows from a rim part while securing high washing performance by being configured to supply washing water to the rim part at a high flow rate by making good use of a jet pump operation.SOLUTION: A water closet device is configured to execute a first stage of supplying water to a discharge part at a first flow rate and a second stage of supplying water to the discharge part at a second flow rate smaller than the first flow rate successively to the first stage during a process in which the water is supplied from a tank to the discharge part by a jet pump unit and a water level in the tank falls from a water full level down to a position of a suction port 321. A flow passage state of the jet pump unit in the second stage is switched so that a jet pump operation in the second stage is suppressed more than a jet pump operation in the first stage. Further, the water closet device includes an adjustment mechanism for adjusting one of a suppression amount for the jet pump operation in the second stage and timing of shifting from the first stage to the second stage.</p> |
