The present invention relates to a sewage discharge device of a variable water-saving toilet, the device discharging sewage in a bowl to the outside by the load of an auxiliary tank, when a part of tap water branches off from a tap water inflow path such that the tap water stored in the auxiliary tank provided around the outer periphery of a sewage discharge pipe of the toilet reaches a predetermined amount or more.

An apparatus for controlling the waste outlet of a toilet includes, according to an implementation, a motor comprising a Hall effect sensor that detects the rotation of the motor and generates a position signal in response thereto; a mechanical actuator coupled to the motor; a door coupled to the mechanical actuator, wherein the door is disposed at the waste outlet of the toilet; logic circuitry that receives the position signal, generates a control signal to move the door based at least in part on the position signal, and transmits the control signal to the motor. The motor operates according to the control signal to drive the mechanical actuator to move the door.

An intermittent fluid delivery system includes a fill tank and a batch tank which is connected to the fill tank via a first pump and a first hose. The fill tank holds a first quantity of fluid. The batch tank holds a second quantity of fluid, which is lesser than the first quantity. The first pump delivers fluid from the fill tank to the batch tank. A second pump delivers fluid from the batch tank to a receiving tank.

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.
