Abstract: A plume cleaning system for a toilet is integrated with a toilet. In one example, a plume cleaner assembly adjacent to a toilet seat is independently removable with respect to the toilet seat. The plume cleaner assembly may include a plume cleaner, apertures, and a fan positioned to draw plume air through the plurality of apertures for treatment by the plume cleaner and expel the treated plume air out of the plume cleaner assembly in a direction at an angle to the apertures. In another example, a plume cleaner assembly with the toilet seat may include at least a fan, an electrostatic collector, and a mist generator. In another example, a plume cleaner assembly is integrated in a tank of the toilet to generate a sanitization fluid that is channeled into the toilet bowl through an overflow tube and/or rim channels.

Abstract: A toilet that includes a bowl; a tank having a sidewall and a bottom defining a reservoir; a container located inside the reservoir and configured to contain a chemical compound that mixes with water to form a cleaning compound; a connector for coupling the container to the sidewall; and a flush valve. The connector has a bracket coupled to the container, a threaded protrusion that extends from the bracket into a hole in the sidewall of the tank, and a threaded fastener having a threaded body and a head, which is larger radially than the threaded body such that the head contacts an outside of the sidewall in a secured position in which the threaded body threads to the threaded protrusion. The flush valve is fluidly connected to the container to introduce the cleaning compound into the bowl through an outlet in the bottom during a cleaning cycle.

Abstract: A pressure toilet has a trapway providing “as needed” (bulk dependent) siphon assist. During normal liquid waste or low bulk flushing, no siphon is formed in the trapway, and the water and light waste in the bowl are evacuated solely under the force of the pressurized jet of water. A large volume near or just downstream from the dam is provided to accommodate the blow out from the water jet. Only upon reaching a threshold concentration of bulk waste material in the down leg does the trapway draw a siphon. A horizontal baffle at the lower part of the down leg assists in the accumulation of bulk material of sufficient concentration to establish a siphon in the trapway.
