  • Patent number: 6928666
    Abstract: A ventilation system is self contained on a toilet. The ventilation system has an enlarged vent pipe located in the water tank that communicates with the upper rim ducts of the toilet bowl. The vent pipe extends out of the water tank and reenters the toilet via the drain channel at a location downstream of the water trap. The vent pipe has a float valve in the water tank to prevent the tank from overflowing. A fan in the vent pipe exhausts the air from the toilet bowl; a flapper valve on the vent pipe end acts as a one-way valve preventing the flush from entering the exhaust duct.

  • Patent number: 6000070
    Abstract: A toilet provides a traditional water filled bowl with flushing action as well as a bidet in one unit. Heated air is forced into the toilet bowl interior and directed onto bidet washed surfaces for drying. Water is directed into the bowl under pressure for flushing and for operating the bidet. The upper rim of the toilet bowl contains a channel which dispenses flush water downwardly for cleaning the interior of the toilet during flushing. Flush water is also directed from two additional outlets to provide flushing action. The toilet is fixtured for wall mounting at an adjustable height which may be changed by merely repositioning mounting bolts on a pair of vertical supports. Sewage pipes are telescoping or extendable for accommodating a vertical positioning range.

  • Patent number: 5930844
    Abstract: A ventilation arrangement for a commode that is refilled after flushing with a water supply valving includes a tank with the water containing portion, a drain pipe for communicating between the tank and a bowl and an air transmission conduit that includes a blower and a blower ventilation duct that extends from the drain pipe to the blower for pulling a suction on openings within the base of the commode. An air flow control arrangement includes a housing that provides resistance to water flow into the air ventilation duct during a flush even while the blower is ventilating. During a flush, air flow seeks a path of least resistance through the housing. After flushing occurs, air flow seeks a path of least resistance through the closed tank drain line to the openings in the bowl.

  • Patent number: 5519899
    Abstract: A toilet odor venting apparatus which fits over the top tank of a toilet in place of the usual tank cover. The apparatus draws air from the toilet bowl through the flush ring into the interior of the tank and then into the room in which the toilet is located. The apparatus includes a suction blower assembly which includes a low profile, disk-shaped impeller journalled for rotation about a vertical axis and one or more low profile electric drive motors, which are preferably DC and which operate at supersynchronous speed. The assembly further includes a special coupling for coupling rotary power from the motors to the impeller with the coupling assembly including a driven wheel journalled for rotation about a vertical axis and a drive wheel journalled for rotation about a horizontal axis. The electric motor is preferably powered by DC current from a battery.

  • Patent number: 5305472
    Abstract: A toilet ventilation unit including a vacuum motor mounted in the wall voids surrounding the toilet that is connected to the back of the tank and utilizes the water passageway of a conventional toilet to draw odors and aromas from the toilet. A vacuum shut off valve is mounted adjacent the back of the tank and is actuated concomitantly with the rising and lowering of the water level to cut off the air flow from the toilet. An additional valve is also mounted adjacent the tank to act in opposition to the shut-off valve and provide relief from the vacuum created from the drop of the water level during flushing. A release valve is adjacent the vacuum motor to draw air from an air source alternative to the toilet, when the shut-off valve is activated.

  • Patent number: 5123125
    Abstract: A flushing tank for a toilet has a housing which accommodates a body of flushing water. An evacuating unit is disposed in the flushing water and includes a flushing valve, a vertical tubular member whose lower end constitutes part of the flushing valve and a vertical suction pipe for the removal of foul odors from the toilet. The upper end of the suction pipe is connected to the upper end of the tubular member while the lower end of the suction pipe communicates with a filter or with a line which conducts foul odors away from the toilet. A suction generating unit draws foul air into and through the suction pipe. The tubular member is movable up-and-down to open and close the flushing valve. The evacuating unit is mounted in an opening in the bottom of the housing and the opening is connected to the toilet bowl. The flushing water flows through the flushing valve and the opening into the toilet bowl when the flushing valve is opened.

  • Patent number: 4998299
    Abstract: A toilet wherein the bowl is connected with the lower end of a flushing tank by a conduit which also serves for evacuation of malodorous air prior to flushing. The valve which can be opened to admit flushing liquid into the bowl has a valving element at the lower end of a duct which communicates with the conduit and the upper end of which is located above the level of flushing liquid in the tank. The apparatus for evacuating malodorous air has a pipe which is installed in the duct and has an intake above the liquid level as well as an outlet extending through and outwardly from the bottom wall of the tank. An odor barrier in the tank can seal or establish a path for the flow of air from the bowl by way of the conduit and duct and into the intake of the pipe so that a fan which is installed at the outlet of the pipe can draw air from the pipe and convey it into a flue.

  • Patent number: 4989276
    Abstract: This invention relates to a ventilated toilet system for removing obnoxious odors from the toilet bowl and includes integral vent channels formed along the base and the back inside of the water tank, and a vent adapter mounted inside the passage that directs the flow of ventilating air along the vent channels to an exhaust pipe and discharges it by a remote in-line exhaust fan to the outside atmosphere. The adapter is attached to the base of the overflow flush valve pipe or, conversely, designed to be an integral part of the overflow flush value pipe, itself, and is positioned to connect the base vent channel of the water tank to the toilet water inlet chamber of the bowl for passage of ventilating air, and to connect the overflow flush valve pipe to the water inlet chamber for passage of flush water.

  • Patent number: 4439874
    Abstract: A quiet water closet rim and a method for venting air from a rim cavity of a water closet. The rim has a horizontally oriented annular cavity and is selectively supplied with pressurized water by a flush mechanism. A series of perforations in the rim permits the pressurized water within the rim cavity to exit the rim in the form of a spray. The rim is also provided with a vent passageway having an inlet open into an upper portion of the cavity and an outlet open into the atmosphere. As pressurized water fills the cavity, a portion of the air within the upper portion of the cavity is vented through the vent passageway.

  • Patent number: 4318192
    Abstract: A ventilated toilet includes a flapper valve assembly having coaxial air intake and air discharge tubes, the outer air intake tube being connected at its lower end to the flush discharge outlet of the holding tank of the toilet. The inner tube protrudes downwardly through the flush discharge outlet and through the porcelain wall separating the siphon portion of the toilet waste discharge duct from the flush conduit connecting the flush discharge outlet of the holding tank to the annular water discharge channel in the rim of the toilet bowl. An electric fan withdraws contaminated air from the toilet bowl through the annular discharge channel and upwardly through the annular channel between the inner and outer flapper valve tubes and vents downwardly through the inner tube to the siphon portion of the waste duct to be discharged. A conventional flapper valve is offset from and connected to the outer one of the pair of coaxial tubes.
