Abstract:
A plumbing fixture includes a receptacle for receiving waste, a tank for storing water, and an electrically operated pump that conveys water from the tank into the receptacle to flush the waste through a drain. The duration that the pump in operated to flush the waste is altered in response to variation of the electrical voltage supplied to the plumbing fixture. The pump is operated to decrease the amount of water in the tank when that amount is sensed to be excessive. Further operation of the pump is inhibited for a given interval to avoid overheating when the pump has been operating too frequently. The pump is cycled on and off in predefined patterns to indicate different malfunctions to a user.
A canister type flush valve has an upright cup-shaped hollow float working under buoyancy forces without a captured air volume that controls the valve during a flush cycle. Hooded bleed openings at a bottom wall of the float can be sized and numbered to selectively control the closuring timing of the valve. Baffles of the hood bleed openings redirect water bleeding into the float to prevent the water from spraying up against the top of the tank. The geometry of a seal retaining groove is designed to reduce leakage at the float/seal interface. For example, the groove has an annular wall with a compound profile forming a non-cylindrical, preferably serpentine, seal contact area. The seal is backed by a slotted flange located just above the retaining groove.

Abstract:
A toilet has an electronic flush assembly operable in either a short or long flush sequence selectable by a user. The long flush sequence includes a pre-rinse cycle and a rinse cycle in which the a supply valve and a flush valve are both opened and closed twice, once each first during the pre-rinse cycle and again during a subsequent rinse cycle. The rim supply valve and the flush valve are opened during the pre-rinse and rinse cycles but are closed at the start and end of each cycle. An electronic control controls operation of the valves as well as water supply control components. Level sensors can also be included to provide feedback to the controller, for example, to prevent overflow conditions.

Abstract:
Disclosed is a plumbing fixture (e.g. a bidet or toilet) of the type having a frontal basin and means for directing a supply of water to the basin for cleaning the basin. The plumbing fixture includes a modular housing mountable behind the basin and at least one control positioned in the modular housing to control operation of the plumbing fixture. The control may be selected from the group consisting of light controls, bidet wand position controls, bidet wand heated air supply controls, bidet wand water supply controls, lid position movement controls, seat position movement controls, deodorizer controls, audio device controls and ultra violet sanitizer controls.

An assembly for connecting a plumbing conduit to a wall is disclosed. In one aspect there is an outlet formed in a wall of the tank and a resilient seal bearing against an inner surface of the wall around the outlet. The seal has a bore aligned with the outlet. A connector tube sandwiches the seal against the wall and also extends through the bore and outlet. The connector is held in place by a radially outwardly extending flange and a locking ring inside the connector.

Abstract:
A toilet ventilation device includes a housing that defines an air inlet aperture and an air outlet aperture. Within the housing are an air movement apparatus for drawing air into the device, a filter for removing malodorous elements in the air, and a radar sensor for activating the air movement apparatus in response to the presence of a user and, optionally, deactivating the air movement apparatus when the user leaves. The toilet ventilation device is configured and arranged to draw air, using the air movement apparatus, from the toilet, through the air inlet aperture, into contact with the filter, and out the air outlet aperture. In one embodiment, the toilet ventilation device is disposed over the overflow conduit of the toilet to draw air from the bowl of the toilet, through the overflow conduit, and into the toilet ventilation device. The entire toilet ventilation device is preferably disposed within a tank of a toilet.
