Abstract: A switching mechanism is configured to switch an advancing direction of water injected from a nozzle by moving between a first position and a second position. The switching mechanism is held at the second position by a force received from the water injected by the nozzle during the tank water feeding process. A refill mechanism has a refill pipe for causing the water injected from the nozzle during the tank water feeding process and whose advancing direction is switched by the switching mechanism to flow in through an inflow port on one end side. The refill pipe is configured to lead the water having flowed in through the inflow port to a toilet stool body without flowing through a suction port of a throat pipe.

Abstract: A flush toilet includes a toilet main unit, a reservoir tank, and a connecting pipe member configured to connect the toilet main unit and the reservoir tank in a watertight manner after the connecting pipe member is inserted into the reservoir tank so that the reservoir tank is assembled to a predetermined installation position. The connecting pipe member includes a communicating pipe portion configured to communicate between the conduit of the toilet main unit and an interior of the tank when one end of the connecting member is inserted from the interior of the tank through the outlet of the tank into the inlet of the conduit of the toilet main unit. A horizontal adjustment portion configured to adjust the orientation of the reservoir tank to a horizontal state is provided on the toilet main unit or on the reservoir tank.

Abstract: A flush toilet apparatus that can reduce the total amount of wash water supplied to a bowl portion, even though a jet-pump water supply mechanism is mounted on a toilet body. A jet pump unit induces a jet pump action for making a flow rate of water flowing inside of a throat pipe higher than a flow rate of water injected from a nozzle to supply water at the increased flow rate to water ejection portions, and the flush toilet apparatus switches a channel state of the jet pump unit to sequentially execute a first step, in which water at a first flow rate is supplied to the water ejection portions, and a second step, in which water at a second flow rate lower than the first flow rate is supplied to the water ejection portions.

Abstract: This flush toilet apparatus includes a traveling-direction switching mechanism switching a mode between a toilet washing mode and a tank storage mode. This traveling-direction switching mechanism includes: a shield portion directing jet water to an outside of a throat pipe at a time of the tank storage mode; a moving mechanism moving the shield portion from a position at a time of the toilet washing mode in a first direction to a position at the time of the tank storage mode; and a guide surface switching a traveling direction of the jet water so that after the traveling direction is switched, a flow rate of the jet water is higher in a second direction opposite to the first direction than in the first direction.

Abstract: A flush toilet apparatus for discharging waste by a jet pump action is disclosed. The flush toilet apparatus has an overflow portion configured to overflow a portion of flush water flowing from a throat pipe into a water conduit into a reservoir tank so that when the flow rate of water flowing inside the throat pipe exceeds a predetermined specified flow rate, the flow rate of water supplied from the water conduit to a bowl portion is reduced to less than a predetermined specified flow rate.

Abstract: A flush toilet apparatus that can reduce the total amount of wash water supplied to a bowl portion, even though a jet-pump water supply mechanism is mounted on a wash-down toilet body. A jet pump unit induces a jet pump action for making a flow rate of water flowing inside of a throat pipe higher than a flow rate of water injected from a nozzle to supply water at the increased flow rate to water ejection portions, and the flush toilet apparatus switches a channel state of the jet pump unit to sequentially execute a water flow forming step, in which water at a first flow rate is supplied to the water ejection portions, and a water flow maintaining step, following the water flow forming step and in which water at a second flow rate lower than the first flow rate is supplied to the water ejection portions.
