ABSTRACT:
A toilet ventilation system moves air from within a toilet bowl and through a filter, or alternatively, out of the building by means of an exhaust pipe or duct. The ventilation system provides a toilet seat assembly having an air channel defined by the lower surface of the seat. An air channel cover is removably held in place on the lower surface of the toilet seat, covering the air channel. By removing the air channel cover the user may easily clean the air channel. A bowl-mounted base and enclosure is attached to the toilet bowl by means of the standard mounting bolts used to attach toilet seats. The toilet seat and lid are pivotally carried by the bowl-mounted base. A reservoir with a drain opening prevents the passage of liquid into a fan and filter housing. The fan and filter housing, carried by the bowl-mounted base, contains a fan powered by a direct current electrical system and an activated charcoal filter.
