A toilet having a water inlet structure, a bowl structure, a rim, and an outlet structure. The water inlet structure is configured to receive water from a water source. The bowl structure includes a toilet bowl and a water channel, which is fluidly connected to the water inlet structure and is configured to feed water into the toilet bowl from an outlet of the water channel that is located between a back portion and a side portion of the toilet bowl. The rim has a solid, annular member disposed around a top of the toilet bowl and entirely above the water channel, is formed separately from and coupled to the bowl structure. The outlet structure is fluidly connected to the toilet bowl to carry the water and contents from the toilet bowl to an outlet.

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.

An apparatus and method for a toilet which minimizes water usage and that can handle both urine and fecal matter. An ultrasonic vibration cleaner unit is disposed to clean at least one fecal plate which is rotated into a lower part of a toilet bowl containing water. Occasional and periodic flushing of solid fecal matter results in less water usage than utilizing water flushing for cleaning and carrying away of solid fecal matte each time of use.

A toilet that includes a bowl having a sump, a passageway, a fluid conduit and a valve. The passageway includes an entrance fluidly connected to the sump, an outlet, a dam located between the entrance and the outlet of the passageway, and an inlet located between the dam and the outlet of the passageway. The fluid conduit configured to supply a volume of water into the passageway through the inlet. The valve located between the inlet and the outlet of the passageway, wherein the valve is configured to retain the volume of water in a closed position prior to a flush cycle to affect a siphon during the flush cycle.

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.

An apparatus for controlling a waste outlet of a toilet includes a flush handle that is rotated by a user. A valve pinion arm is coupled to the flush handle and a waste discharge valve disposed at the waste outlet of the toilet is coupled to the valve pinion arm at an opposite end. The rotation of the flush handle is configured to move the valve pinion arm in a first direction. The movement of the valve pinion arm is configured to move the waste discharge valve to an open position. Upon release of the flush handle, the valve pinion arm is configured to move in a second direction and to move the waste discharge valve to a closed position. According to an embodiment, the apparatus includes an actuated flush control mechanism and a manual flush control mechanism.
