A flush toilet is provided, which can enhance discharge performance of waste from an inside of a water discharge trap conduit even with a smaller amount of flushing water, in the flush toilet discharging waste by a siphon action. A flush toilet of the present invention has a bowl section, a water discharge trap conduit, and a jet spout port connected to a lower portion of the bowl section and opened toward the water discharge trap conduit, with an outlet portion bottom surface of an outlet portion thereof and a bottom surface of the bowl section being connected, and a bottom surface of the bowl section forms a curved surface that diagonally inclines more downward than the outlet portion bottom surface from a tip end of an outlet portion bottom surface of the jet spout port.

The present utility model relates to the field of manufacture of sanitary wares, and provides a toilet. The toilet includes a seat body with a sewage accommodating bowl, and a cistern. The inside of the cistern is provided with a fill valve, a first ring flushing pipeline, a first water inlet end of the first ring flushing pipeline is selectively in fluid communication with the fill valve, a first water outlet end of the first ring flushing pipeline is in fluid communication with a ring flushing port opening, and the first ring flushing pipeline includes a first jet flow increasing structure; a second bottom flushing pipeline, a second water inlet end of the second bottom flushing pipeline is selectively in fluid communication with the fill valve, and the second bottom flushing pipeline includes a second jet flow increasing structure; and a pipeline switching mechanism, being able to automatically switch the fluid communication between the first ring flushing pipeline and the fill valve or between the second bottom flushing pipeline and the fill valve in response to a water level in the cistern. By using such toilet, the sewage accommodating bowl can be more cleanly and thoroughly flushed with the same water consumption, or a low-profile cistern design can be realized under the same water pressure requirement.

A flush assembly for a toilet with a tank can include a rigid siphon body with a siphon inlet, a siphon outlet, and a siphon passage. An outlet assembly can be coupled to the siphon outlet to provide a liquid flow path between the siphon outlet and a flush port of the tank. The rigid siphon body can be configured to float within the tank and to be submerged to establish a siphon-driven flow of liquid from the tank to the flush port to flush the toilet.

A toilet assembly, comprising a toilet tank to hold flush water; a flush valve assembly positioned in the toilet tank; a toilet bowl; and a trapway inflow communication with the toilet bowl, wherein, the flush valve assembly comprises a container having an open lower end and a closed upper end; a siphon flush valve positioned in the container upper end; and a conduit positioned in an interior of the container, wherein the container is in flow communication with the toilet tank, the conduit is coupled to the trapway and provides flow communication between the container and the trapway, and the siphon flush valve comprises a tubular core, a head surrounding a top of the core, and a fluid spray initiator coupled to the head, the spray initiator configured to discharge water into the core to induce a siphon flow of surrounding tank water through the core.

The present invention is a flush toilet apparatus including a flush toilet main body that includes a bowl, a water discharge trap pipe, an upper water discharge port, and a lower water discharge port, and a flush control device configured to execute a large flush mode and a small flush mode, in which the flush control device causes the flush water to be discharged from the lower water discharge port with substantially the same amount in each of the large flush mode and the small flush mode to induce a siphon phenomenon in the water discharge trap pipe, while controlling the water discharge from the upper water discharge port so that a water level of pooled water in the bowl during the water discharge from the lower water discharge port is changed between the large flush mode and the small flush mode.

A toilet flushing assembly includes at least a spiral trapway and a drive mechanism. The spiral trapway includes an upstream portion coupled to a toilet bowl, a curved portion, and a downstream portion coupled to a waste outlet. The drive mechanism is coupled to the spiral trapway and configured to rotate the spiral trapway from a first orientation to a second orientation. The first orientation evacuates contents from the toilet bowl and the second orientation advances the contents from the spiral trapway to the waste outlet.

A high efficiency toilet configuration including a water tank. The tank includes a supply line, a mechanical valve controlling a flow of water from the line into the tank, and walls and a base. The tank includes a through-hole in the base channeling water out of the water tank and a tank outlet hole including a housing extending through the through-hole. The tank includes an outlet valve configured for selectively prohibiting water from flowing through the tank outlet hole and permitting water through the tank outlet hole during a flush event. The tank includes a water column vessel disposed around the outlet hole and configured for separating water in the water tank between water outside of the vessel and a channel of water contained over the outlet hole. The configuration includes a toilet base including a bowl and a plenum for channeling the water to the bowl.
