Abstract: A siphon jet flush toilet comprises: a bowl; a rim spout port suppling flush water to the bowl; a discharge trap conduit; a jet spout port spouting flush water toward an inlet of the discharge trap conduit; a reservoir tank including a jet spouting discharge valve and storing flush water; a jet water conduit configured to guide the flush water in the reservoir tank to the jet spout port; and a controller being configured to control a rim spouting in which the flush water is spouted from the rim spout port and a jet spouting in which the flush water is spouted from the jet spout port, wherein the jet spouting discharge valve includes a valve body, the valve body being arranged at a position that is lower than an upper surface of the bowl and higher than a seal water level, and before opening the jet spouting discharge valve, the flush water is supplied to the jet water conduit.

Abstract: A flush toilet includes a reservoir tank, a bowl, a rim spout port, a discharge trap conduit, a jet spout port configured to spout flush water toward an inlet of the discharge trap conduit, a jet water conduit configured to supply the flush water from the reservoir tank to the jet spout port, and a discharge device configured to supply or stop supplying the flush water to the jet water conduit, wherein the flush water is spouted at a first flow rate from the jet spout port when the discharge device is driven and the flush water in the reservoir tank flows into the jet water conduit and, after spouting of the first flow rate ends, the flush water is spouted at a second flow rate from the jet spout port due to the flush water retained in the jet water conduit flowing toward the jet spout port.

Abstract: The present invention is a flush toilet (1) including: a bowl portion (8) having a bowl-shaped waste receiving surface (16), a rim portion (18), and a well portion (20) formed at the bottom of the waste receiving surface; a discharge trap pipe (12) connected to the bottom portion of the well portion; a flush water guide portion (40b) disposed on the waste receiving surface at the rear of the well portion so that flush water is directed toward the side wall surface inside the well portion; and a liquid membrane spouting portion (24) disposed on the rim portion, wherein this liquid membrane spouting portion induces a vertical circulating flow in the well portion, produced when discharged flush water assumes a liquid membrane form and collides with a flush water guide portion, and the colliding flush water drops along the side wall surface of the well portion.
