  • Patent number: 7275271
    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.

  • Patent number: 5079783
    Abstract: A rechargeable self-contained deodorizing toilet seat is provided for installation on any standard toilet to remove bathroom odors. The seat is substantially the same in size and appearance as a standard toilet seat. Air conduits pass though the right and left sides of the seat member from the lower surface to the outer surface. The conduits contain activated carbon air filtration media and blowers for moving the air. Seals on the lower surface seal the seat to the toilet rim except at the front where ducts are provided for the introduction of fresh air. Lips on the inner edges of the ducts deflect air down into the bowl. The blowers are rotated by direct current electric motors powered by rechargeable batteries. Operation of the motors is controlled by switches which close only when the lid is raised and weight is placed on the seat. An electronic timer turns off the air filtration system after a preset period of time to conserve the battery power.
