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.

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.

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.

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.

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.

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.

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.
