Abstract: A bathroom deodorizer and odorizer for use with a conventional toilet bowl comprising housing means, said housing means provided with a motor chamber therein, said motor chamber opening externally of said housing, said housing provided with first and second inlet ports and chambers and first and second outlet ports and chambers, said first inlet port and chamber communicating with said first outlet port and chamber and said second inlet port and chamber communicating with said second outlet port and chamber, motor means provided with a first and second fan means operably mounted in said motor chamber, said first fan means disposed in said first outlet chamber and said second fan means disposed in said second outlet chamber, said motor means provided with energy coupling means operably mounted thereon, a motor chamber cover provided with energy coupling means operably mounted thereon operably mounted on said housing means, deodorizing or odorizing wafer removably disposed in said first and second inlet chamber

Abstract: A water closet has an intake manifold interposed between the seat and the top periphery of the bowl. A suction blower is arranged to draw gases from the manifold, and deliver them to the sewer connection beyond the water trap. The components, including the ventilation connection, are within, or secured to, the bowl and tank structure.

Abstract: A vacuum flush waste disposal system for aircraft; wherein, the required vacuum is acquired at altitude through the differential pressure between the aircraft cabin pressure and the ambient pressure above approximately 15,000 feet. When the aircraft is below this altitude or on the ground, the vacuum is provided by a blower. For flushing the toilet bowl, a timing device is initially actuated and functions: to introduce a recirculated flush fluid into a flush ring in the upper portion of the toilet bowl; and to open a drain in the lower portion of the toilet bowl, leading to the vacuum waste line; whereby, the waste and flush water are rapidly propelled through the waste line towards a centrally located holding tank, by the differential pressure acting upon it. Once in the holding tank, the waste fluid is filtered out for further use as the recirculated flush fluid.

Abstract: An improvement directed to toilet deodorizers, ventilators and air fresheners of the type which induce odorous air from the toilet bowl via the water tank overflow conduit. Such accessaries are subject to water vapor intrusion from the water tank. A normally-closed air valve means impedes the water vapor intrusion when the accessary is not in use.

Abstract: A timed ventilator for toilets which mounts entirely within the toilet tank, and which operates from a battery power source to remove air from the toilet bowl and move the air through a charcoal filter for deodorizing. An external control includes an automatic time delay which will hold the fan on for a desired amount of time necessary to change the air in the small volume of the toilet bowl.
