Combined With Flusher Patents (Class 4/224)
  • Patent number: 10519643
    Abstract: Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a tank, a flush valve, and a rim in fluid communication with the bowl through a rim flow path from an outlet of the flush valve to at least one rim outlet port. The flush valve is configured to operate in a flush actuation mode wherein the flush valve is able to provide flush water flow sufficient for the toilet assembly to initiate a flush siphon or provide a wash down flush and to operate in a cleaning actuation mode wherein the flush valve is only partially opened to allow for introduction of a cleaning agent and flush water mixture to the bowl that is insufficient to initiate a siphon but sufficient for cleaning the bowl.

  • Publication number: 20150128336
    Abstract: It is disclosed a system for dispensing a cleaning fluid into a toilet bowl adapted to receive a flushing liquid from a tank. The system includes a cleaning fluid container positioned outside the tank and a valve controlling fluid passage from the container into a flushing liquid filling the tank at a varying level. The valve has a closed state and an open state blocking and enabling, respectively, fluid passage thereof. The valve switches between the states by the varying level. A conduit communicates the container with the valve, receives the cleaning fluid from the container, and releases it to the flushing liquid through the valve. A bottle base is attached to the tank for receiving a mouth end of a dispenser bottle. The dispenser bottle has a diaphragm for sealing the dispenser bottle and a punching pin punches the diaphragm while the dispenser bottle is brought into the bottle base. Thus, the pin enables a flow of a cleaning fluid out of the dispenser bottle.

    Abstract: A method of operating a toilet freshener includes the step of flushing water flow through a toilet bowl within a flushing water period [t1-t2], in which t1 represents the start of flush water flow and t2 the end of flush water flow. A sensor unit detects triggering of a flush water stream through the toilet bowl within the flushing water period [t1-t2] at a time ts. A sensor signal, which represents triggering of the flush water stream, is sent to a control unit. The sensor signal is converted, using the control unit, into a control signal for the release element, in response thereto, to release preparation from the container into the interior of the toilet bowl, release of the preparation from the container taking place with a time delay ?t after detection of the flush stream by the sensor unit and continuing for a first preparation release period ?t1.

  • Patent number: 6510561
    Abstract: A dispensing device comprising a body defining first and second compartments, separated by a flexible impermeable membrane. The second compartment is closed off by a semi-permeable membrane adjacent which a water container is disposed. An apertured delivery tube leads from the first compartment. The device may be used to dispense a cleaning, disinfectant and/or fragrancing gel into a toilet bowl. On flushing, water enters the container and migrates through the semi-permeable membrane, increasing the pressure in an osmotic agent or swellable hydrogel contained in the second compartment. This imposes a pressure on the flexible impermeable membrane to displace a gel from the first compartment into the toilet bowl through apertures in the tube.

  • Patent number: 6256802
    Abstract: Apparatus for injecting a reagent into a stream of pressurized rinse fluid delivered to a vacuum toilet. The apparatus is pressure-operated in response to the flow of pressurized rinse fluid, thereby eliminating the need for electric outlets or controls. The apparatus includes an orifice located in a main conduit upstream of a reagent discharge outlet. The orifice reduces the pressure of the rinse fluid thereby to unload a check valve which controls injection of the reagent into the rinse fluid stream. In addition, the volume of a pump chamber for holding reagent is reduced to ensure that the pump maintains its prime. Furthermore, the piping leading into the pump chamber has a relatively uniform inside surface and a tapered insert is used to reduced the cross-sectional area of the reagent extreme, thereby directing air bubbles through the pump chamber.

  • Patent number: 6000067
    Abstract: An adapter for automatically dispensing any aromatic, deodorizing, cleansing, sanitizing fluid directly into the bowl of a recreational vehicle toilet as a result of operating either the bowl rinse or the bowl flush control. An apparatus adapted to toilets installed in recreational vehicles, travel trailers, an marine craft. Because it passively senses the presence of toilet inlet rinse water flow, the apparatus achieves its objective without making modifications to, and is totally independent of, the RV plumbing system. The adapter utilizes an electronic control unit which employs the electrically conductive property of water to detect the flush and the refill operations of the RV toilet. Upon detecting fresh water entering the toilet, the electronic control unit energizes an electric solenoid valve which releases a metered amount of chemical additive fluid directly into the toilet bowl. The chemical additive flow rate is fully adjustable by the user, and the chemical fluid reservoir is refillable.

  • Patent number: 5123124
    Abstract: A toilet system providing improved convenience, efficiency and sanitation with automatic operation. Basically, the toilet includes a bowl, a seat partially covering the bowl opening and a lid movable between a raised position exposing the seat and a lower position covering the seat and sealing the bowl. When the lid is raised, an air extraction system removes air and odors from the bowl. After use, the lid is either manually or automatically closed, initiating a high or low flush. When left to close automatically a low flush only is initiated. In a low flush, water is directed under pressure through two rotating spray jets against the bowl interior, then is removed along with any toilet contents by the rotating jets action and the macerator which reduces solids to small particles. Heated air is then directed into the bowl to dry the bowl. In a high flush, an additional spray jet cleans the seat and a larger quantity (typically 1/3 additional) of water is used.

  • Patent number: 4984306
    Abstract: The invention relates to an automatic chemical injection system for injecting metered amounts of chemical into flush water as the flush water enters a toilet. The injector assembly is easily mounted into the flush water supply line. The assembly has an injector housing which has a truncated cone-shaped bore therein through which the flush water passes. The truncated cone-shaped bore has a smaller diameter opening which increases to a larger diameter opening in the direction of water flow. A smaller bore intersects the cone-shape bore adjacent the smaller diameter opening so that a venturi effect occurs at the opening of the smaller bore. The smaller bore is interconnected to a chemical reservoir so that chemical is pulled into the flush water as the flush water passes the smaller bore. A check valve is located in the smaller bore to permit chemical to be metered into the flush water but not permit flush water to back up into the chemical reservoir and dilute the chemical reservoir.

  • Patent number: 4841578
    Abstract: A sanitizer for recreational vehicles is interposed between the toilet flush valve and the toilet itself. It utilizes an upright canister which maintains a substantial air pocket to prevent back-flow, there being a charge of sanitizing chemicals in the bottom of the canister which dissolve slowly in the water that is introduced into the canister to flush the toilet. An inverted U-shaped tube introduces the fresh water into the canister, and by virtue of a vertically, downwardly extended length of the U-shaped tube which extends down into the canister, the sloshing of water into a downhill portion of the fresh water system is inhibited.The system overcomes the prior art arrangement in which a charge of chemicals is dumped into the holding tank with every tank flush, and it adds the anti-back-flow or anti-reverse-syphon protection of a three-stage prophylactic.
