ABSTRACT:
A toilet is provided which transports malodorous air from the bowl to the sewer line. The tank of the toilet is equipped with a fan which draws air from the bowl through the flush holes, located in the rim of the bowl, into a sealed fan box. An intake tube is used to channel air from the water inlet to the fan box, which leaves the overflow tube unobstructed. Air is diverted out of the fan box through an exit tube which attaches to the siphon at a point behind the water trap. A damper door disposed between the exit tube and intake tube prevents stale air from the siphon or sewer from entering the bowl or tank and escaping.
