Abstract: The odor removing toilet fixture has fully integrated exhaust ventilation for removing odors from the toilet bowl and surrounding areas while maintaining the same fit, form, and function of non-ventilated toilet fixtures for easy retrofit in homes and buildings. The fixture also incorporates two valves for controlling both water and airflow during operation.

Abstract: The technology described herein provides an odorless and overflow-less toilet system. The technology provides for the removal of odor at its source and aids in overflow protection. The technology provides a toilet system having a second chamber running in fluid communication with a first chamber and a second exit port to allow for the continuation of the second chamber flow to a trap assembly. The trap assembly is configured to separate exhaust odors and overflows. The trap assembly prevents sewage gasses from escaping back through the toilet. The trap assembly allows overflows to be routed back to a sewage out line. The trap assembly provides for the flow of odors from the toilet with an inline exhaust fan. The inline exhaust fan pulls odors from the toilet through the second chamber and exit port of the toilet through the trap assembly and then through the inline exhaust fan to exit.

Abstract: A ventilation system for a toilet which functions by drawing air from around the bowl through the original flush holes into the existing overflow-pipe and then into a fan compartment. The fan is activated by manipulating the flush handle upward. Malodorous air is then forced through an exhaust pipe into the sewage line downstream of the gas trap. The fan is deactivated when the flush handle is pressed downward and the toilet is flushed. A water-trap between the fan and the toilet tank prevents the malodorous air from escaping into the tank. The water in the water trap is changed with each flush by redirecting the refill tube into the water trap. This prevents the water in the water trap from becoming stagnant.

Abstract: An odor eliminating system utilizes an air pump to remove odors from a bowl of a toilet to a trap of the toilet. By moving the odors to the trap, the odors cannot escape back to the bowl and can only proceed out of the toilet to the sewer. The system can be adapted to existing toilets by drilling a channel to the trap or the system can be incorporated into new toilets.

Abstract: The flushing device comprises a flush bowl (1) comprising an odor trap (8) on a bottom part (7) and comprises a flushing conduit (2) with flushing openings (14, 15, 16) on an upper edge (3). Flushing openings (14) in a frontal area (13) of the flushing conduit (2) have a greater throughput than laterally arranged flushing openings (15, 16) do. The flushing openings (4) in said frontal area (13) are arranged in an asymmetric manner and the flushing water (17) forms a flushing vortex (17c) in the bowl (11). The flushing device makes it possible to effectively flush with less flushing water.

Abstract: A multifunction toilet is shown with a conventional flushing system and auxiliary components which include an odor exhaust system which withdraws gases from the toilet bowl and delivers them to the sewage drain downstream of the toilet water trap. Other auxiliary components include a motor driven retractable nozzle pipe which provides a personal warm water spray rinse and a dryer which supplies warm drying air. The auxiliary components are operated under a switch control system which assures proper sequencing and prevents use unless the user is seated on the toilet seat.

Abstract: The evacuation of foul smelling gases from the interior of a toilet bowl is effected by a fan which is driven by an electric motor and conveys the gases from the bowl through a control chamber in the flushing tank and into an evacuating conduit which is connected to the drain pipe. The motor is started in response to closing of a master switch which is distinct and preferably remote from an actuating knob which must be lifted or otherwise moved in order to enable a body of flushing liquid to flow from the tank into the bowl. A siphon is provided to permit liquid to flow from the interior of the control chamber into the interior of the flushing tank in response to rising pressure in the control chamber.

Abstract: A toilet has a toilet bowl and a flushing tank which accommodates a supply of flushing liquid for the bowl. The bowl, which discharges into a waste line, is connected to the flushing tank by a flushing pipe. A second pipe for evacuating odors from the bowl likewise leads from the bowl to the tank. This evacuating pipe has an open end in the bottom of the bowl and a second end in the tank. An air duct hooked into the waste line also extends into the tank and can be caused to communicate with the evacuating pipe when the toilet is in use. The air duct is provided with a blower which functions to convey odors from the bowl to the waste line via the evacuating pipe, flushing tank and air duct. A liquid seal cuts off communication between the air duct and evacuating pipe when the toilet is not in use to prevent backflow of odors from the waste line to the bowl. The liquid seal is located in the flushing tank and is established using the flushing liquid accommodated by the same.

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.

Abstract: Disclosed herein is a means for evacuating the odors associated with toilet use away from the environment of the bathroom and into the sewer. Vent means are provided around the periphery directly below the toilet seat, and impelling means are provided to channel the air traversing through these vents into the sewer outlet remote from the bathroom interior.
