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.
