Abstract: A toilet dehumidifier assembly for draining reclaimed water into a toilet tank includes a toilet tank lid that has an opening extending through the toilet lid. The toilet tank lid is positionable on a toilet tank. A dehumidifier is attachable to the toilet tank lid to remove moisture from ambient air surrounding the toilet tank. The dehumidifier is aligned with the opening in the toilet tank lid to drain water into the toilet tank. A container is positionable inside the toilet tank to capture the water drained from the dehumidifier.

Abstract: The disclosed technology includes a tank system including a gravity tank configured to contain water at atmospheric pressure, a rigid pressurized tank positioned within the gravity tank and configured to contain water at a pressure greater than atmospheric pressure, and a piston assembly positioned below the rigid pressurized tank and configured to open and close the rigid pressurized tank. The gravity tank is configured to channel water at atmospheric pressure into a toilet bowl at a first velocity and the rigid pressurized tank is configured to channel water at the pressure greater than atmospheric pressure into the toilet bowl at a second velocity. The second velocity is greater than the first velocity.

Abstract: A flush toilet includes a rear storage configured to store a control unit of a toilet main body. The rear storage includes a supporting wall configured to support the control unit so as to divide a storage region of the rear storage into upper and lower regions. In a rear supporting region of the rear storage, a first distance in a horizontal left-right direction from an outer joining portion to an inner joining portion in the supporting wall is shorter than a second distance in the horizontal left-right direction from an outer wall in the double wall of the skirt to an inner joining portion of the supporting wall. The second distance is set to a maximum width dimension in the left-right direction in an internal space of the double wall of the skirt.

Abstract: Devices and methods are provided for sensing and stopping an excessive water-flow condition in a water-using appliance such as a toilet. Such excessive water-flow conditions can occur, for example, when a leak or other malfunction is present in the appliance. The devices measure and monitor the time that elapses after the commencement of water flow to the appliance, and interrupt the water supply when the elapsed time reaches a predetermined value. Alternatively, the devices measure and monitor the cumulative volume of water that flows to the appliance after the commencement of water flow, and interrupt the water supply when the cumulative volume reaches a predetermined value.

Abstract: A flush actuator device with a foot pedal for actuating a flush action at a toilet is provided. The flush actuator device may replace or supplement a manual handle on a conventional toilet and allows flushing action to be initiated by depressing a foot pedal on a floor surface adjacent the toilet. With the flush actuator device, a flush action can be performed using the foot pedal without necessitating any contact with the other parts of the toilet which may be deemed dirty or unsanitary, particularly in public restroom settings. A method of installing the flush actuator device onto an existing toilet is provided. Further, a method for actuating flushing of a toilet using a flush actuator device having a foot pedal is described. The ability to retroactively fit the flush actuator device to an existing toilet eliminates the need for complicated and expensive plumbing fixture replacement.
