ABSTRACT:
A toilet odor venting apparatus which fits over the top tank of a toilet in place of the usual tank cover. The apparatus draws air from the toilet bowl through the flush ring into the interior of the tank and then into the room in which the toilet is located. The apparatus includes a suction blower assembly which includes a low profile, disk-shaped impeller journalled for rotation about a vertical axis and one or more low profile electric drive motors, which are preferably DC and which operate at supersynchronous speed. The assembly further includes a special coupling for coupling rotary power from the motors to the impeller with the coupling assembly including a driven wheel journalled for rotation about a vertical axis and a drive wheel journalled for rotation about a horizontal axis. The electric motor is preferably powered by DC current from a battery.
