Abstract: A flush toilet includes: a water supply channel that allows flush water to be supplied from a flush water storage tank to a rim spout port and a jet spout port; and a switching device that switches a water supply path so as to execute a first flushing process of spouting the flush water in the water supply channel from the rim spout port and after that, execute a second flushing process of spouting the flush water in the water supply channel from at least the jet spout port. The switching device includes a switching valve body that operates by receiving the water pressure of the flush water pressurized by a pressure pump. This switching valve body performs switching to a water supply path that allows the first flushing process or the second flushing process to be executed according to the water pressure generated by the pressure pump.

Abstract: A flush toilet includes a valve apparatus for spouting and stopping water to a storage tank or a toilet main unit supplied from a water supply source, and includes a pressurizing pump, being a reversely rotatable pump including a suctioning portion connected to the storage tank, a rim-side discharge portion connected to the toilet main unit rim spouting portion, a jet-side discharge portion connected to the toilet main unit jet spouting portion, and an impeller; and when the impeller is rotating in one direction, the pressurizing pump spouts flush water in the storage tank to the rim-side discharge portion, whereas when the impeller rotates in the other direction, the pressurizing pump spouts flush water in the storage tank to the jet-side discharge portion, or spouts flush water in the storage tank to both the rim-side discharge portion and the jet-side discharge portion.

Abstract: When a bowl 20d discharges waste with flush water after temporarily receiving the waste, before the waste is transported from at least the discharge trap conduit 40 by the flush water supplied from a flush water supply hole 30d as flush water supply means, the flush toilet device CSd drives a siphon pump 505d and then drives a return pump 506d before the supply of the flush water has been completed.

Abstract: To provide a flow channel opening/closing apparatus that can keep the instantaneous flow rate of supply water, quickly open and close a main valve for starting and stopping water supply and be downsized. A flush valve CV, which is such a flow channel opening/closing apparatus, incorporates constant flow rate keeping part that operates to keep constant the main flow rate of water flowing from a primary-side internal flow channel 20 to a secondary-side internal flow channel 30, and the constant flow rate keeping part has a constant flow rate valve body 44 and a constant flow rate valve seat, operates to adjust the distance between the constant flow rate valve body 44 and the constant flow rate valve seat, and is configured as an integral valve member including a main valve body 42 and the constant flow rate valve body 44.
