A touchless siphon valve assembly for a toilet assembly having a toilet tank, the touchless siphon valve assembly comprising a control assembly and a siphon valve assembly, wherein the control assembly comprises a capacitive sensor, a controller, and a power source, and the siphon valve assembly comprises a tubular core, a head coupled to and surrounding an upper end of the tubular core, a spray initiator positioned in the head and extending into the tubular core, and a solenoid valve fluidly coupled to the spray initiator, the capacitive sensor is configured to detect a user gesture, and to indicate detection of the first gesture to the controller to initiate a flush cycle.

A siphon valve assembly, the assembly comprising a tubular core; a head coupled to and surrounding a top of the core; and a fluid spray initiator coupled to the head; wherein a lower end of the head defines a siphon valve inlet, a lower end of the tubular core defines a siphon valve outlet, an upper end of the tubular core comprises a weir, and the spray initiator is configured to discharge a fluid into the core to induce a siphon flow of a surrounding fluid through the siphon valve inlet, over the weir, and out the siphon valve outlet.

A flush toilet is provided, which can advance timing for startup of a siphon action that discharges waste, and can efficiently discharge waste from a water discharge trap conduit. A flush toilet of the present invention has a bowl section, a water discharge trap conduit connected to a lower portion of the bowl section, and a jet spout port that is opened toward the water discharge trap conduit, in the lower portion of the bowl section, and the jet spout port includes an outlet flow path in which a bottom surface extending toward an outlet of the jet spout port and toward a bowl section bottom surface in the lower portion of the bowl section, and a ceiling surface extending toward the outlet and having an inclination toward an upper direction than an inclination of the bottom surface are formed.

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.
