  • Patent number: 8453272
    Abstract: An automatic cleaning assembly having an outer body and an inner lid which, when attached to each other, may define an inner chamber and an outer chamber. Refill water may enter the inner chamber through a fluid flow path of an inlet. A cleaning agent disposed within the inner chamber may be partially dissolved upon contact with the water. The water with the dissolved cleaning agent begins to fill the outer chamber and exit out of the outlet of the automatic cleaning assembly. The outlet of the automatic cleaning assembly is positioned above the inlet of the automatic cleaning assembly such that water is retained within the outer chamber to prevent gas caused by the cleaning agent from escaping into the environment. Moreover, the automatic cleaning assembly may have a check valve to prevent water from back flowing into a ball cock of the toilet.

  • Patent number: 8095997
    Abstract: A modular cartridge based liquid dispensing system for automatically dispensing a metered amount of liquid(s) into a toilet water tank and/or bowl. This unique programmable system mounts onto a standard water tank, and is shaped to match the tank so that it blends well with the existing toilet design for aesthetics. It is designed to dispense one or a plurality of solution types, allowing any desired solution to be dispensed, such as cleaning solutions and deodorants. It uses replaceable liquid cartridges that can be refillable or disposable, and can also use fixed tanks. This invention can also utilize all of its components in a low-rise cabinet chassis that allows the entire system to be mounted inside the water tank where it is completely hidden from view. The system also has provisions for an optional automatic toilet flushing device and can also be used to dispense its liquids to a bidet apparatus.

  • Patent number: 8015628
    Abstract: Disclosed is a dispenser for dispensing a composition in response to level changes in a liquid in a tank. The dispenser includes a container for holding the composition, a discharge conduit in fluid communication with the container, an air inlet in fluid communication with the container, and a level sensing member mounted to the dispenser such that a lower end of the level sensing member contacts the liquid in the tank and senses its level. In use, a rise of the liquid in the tank between a lower liquid level and a higher liquid level causes the level sensing member to alter air pressure in a headspace of the container above the composition and thereby cause a controlled discharge of the composition from the discharge conduit; and a fall of the liquid in the tank between the higher liquid level and the lower liquid level causes the level sensing member to alter pressure in the headspace and thereby causing air to be vented into the headspace from the air inlet.

  • Patent number: 7007312
    Abstract: Provided is a hydraulic time release system for regulating the flow of liquid therethrough. The time release system comprises a timer body having a timer inlet for providing liquid at a timer inlet flow rate and a timer outlet for discharging liquid at a timer outlet flow rate. The timer body is divided into a first reservoir, a second reservoir, a third reservoir and a float reservoir. The first reservoir includes a catch pan mounted on an open drain tube that is positioned below the timer inlet. The first, second and third reservoirs are in at least partial fluid communication with the float reservoir. A timer float assembly is moveable between open and closed positions in response to variations in the float reservoir liquid level. The closed position is such that the flow of liquid into the drain tube is blocked causing the timer body to fill with liquid whereupon the timer outlet flow rate is substantially equivalent to the timer inlet flow rate.

  • Publication number: 20040194196
    Abstract: An apparatus is provided which is positioned in a reservoir tank of a conventional tank toilet and which injects cleaner into a toilet bowl operatively connected to said reservoir tank when the toilet is flushed. The apparatus includes a “T” connector, a diaphragm valve connected to a collapsible supply bag, an injection tube connected to said diaphragm valve and running the length of said supply bag and exiting the supply bag at the top of the bag through a sealed exit. When the toilet is flushed, the “T” connector diverts water from a water inlet valve located within the reservoir tank and directs the water to the diaphragm valve. The water operates the diaphragm valve, which forces cleaner from the valve through the injection tube, and out the injection tube into an overflow pipe located with the reservoir tank. The overflow pipe leads to the toilet bowl; thus allowing for the cleaner exiting the tube to be enter the bowl to clean the toilet.

  • Patent number: 6321392
    Abstract: An automatic cleaning assembly for a toilet bowl includes a body member having an interior cavity therein for receiving a cleaning agent. An inlet is in communication with an interior of the body member and is connectable to a ball cock through a refill tube and an outlet is in communication with an interior of the body member and is connectable to an overflow pipe through a connecting hose. Furthermore, a cap is attached to the body member. The cap is free from apertures therethrough and sealed to said body member to form a sealed space at an upper portion of an interior of the body member. The sealed space ensures that a level of water within said interior cavity of said body member remains at a bottom of the cleaning agent to slowly dissolve the cleaning agent. With the above construction, an improved cleaning assembly for a toilet bowl is provided, which is simple in structure, inexpensive to manufacture, and can clean the toilet bowl thoroughly.
