<p>PROBLEM TO BE SOLVED: To provide a water closet device capable of reducing the total amount of washing water supplied to a bowl part although a jet pump type water supply mechanism is mounted on a wash-down type toilet body.SOLUTION: A water closet device FT is configured to supply water to water discharge parts 133, 135 at an increased flow rate by inducing a jet pump operation of making the flow rate of water flowing in a throat pipe 320 larger than the flow rate of water jetted from a nozzle 310, and further includes flow passage state switching means of switching the flow passage state of a jet pump unit so as to sequentially execute a water flow forming process of supplying the water to the water discharge parts at a first flow rate by the jet pump unit and a water flow maintaining process of supplying the water to the water discharge parts 133, 135 at a second flow rate lower than the first flow rate by the jet pump unit successively to the water flow forming process.</p> |
