Abstract: Provided herein is a water dam device for installation in the water tank of a toilet to reduce the quantity of water discharged from the tank during flushing while maintaining a satisfactory flushing action.
Abstract: Some embodiments include a fluid control system with an outlet valve assembly, an inlet valve assembly including a venturi inlet valve, and an actuator coupled to the inlet valve assembly. In some embodiments, the actuator can enable a user to control a flush volume of fluid control system. Some embodiments include a moveable float positioned in a chamber of the outlet valve assembly, where the chamber includes a variably-sized upper portion with a volume that is based at least in part on a variable position of the moveable float in the chamber. Some embodiments include a adjustable control valves coupled to an outer surface of the outlet valve assembly and the inlet valve assembly. Some embodiments also include a bellows positioned in and coupled to the variably-sized upper portion. In some embodiments, the bellows are fluidly coupled to the venturi inlet valve and at least one of the control valves.
Abstract: A flush water tank apparatus capable of stable operational control of a discharge valve apparatus, and stable flush water supply to a toilet for long term. The flush water tank apparatus of the present invention includes a power drive unit comprising a motor and an output shaft, being a power drive unit capable of electrically operating a drain valve on a drain valve mechanism; and a housing portion formed so as to surround the perimeter of the outlet on a drive unit internal air passage extending from the motor in the interior of the flush water tank; wherein an air passage communicating from the motor of the power drive unit through the housing portion to the exterior of the flush water tank is formed.
Abstract: Disclosed is a water-saving sit-down toilet wherein the pressure of flushing water discharged from a cistern into the toilet is raised and a straight discharge pipe is used such that the toilet is flushed clean using a small amount of water, and, at the same time, excreta is smoothly discharged as the direct discharge tube is opened and closed by means of the water pressure and a permanent magnet and an electromagnet, and an appropriate amount of residual water is supplied to the toilet bowl such that odors are blocked from rising from a foul-water port into the toilet, and an odor removing unit sucks in odors emanating from the excreta and discharges same through the foul-water port such that the user can use the sit-down toilet without feeling any embarrassment.
Abstract: One embodiment of the present application relates to a water tank for a toilet. The water tank includes a first chamber comprising an orifice for connecting to a toilet bowl. The water tank further includes a free-floating member within the first chamber that is not coupled to any other component and that is configured to selectively engage with and disengage from the orifice to selectively block or allow a flow of water through the orifice. The free-floating member can be selectively disengaged from the orifice via an actuator or a differential pressure within the water tank.
