A ventilating toilet for removing contaminated air from a toilet bowl (1) through a ventilating system which is entirely integral with the plumbing system of the toilet. A ventilation blower (20) is located with a compartment formed in the base portion of the toilet body, generally in front of and beneath the toilet bowl. Contaminated air is drawn through ventilation openings (18) in the toilet bowl rim to the ventilation blower (20) by way of a ventilation passageway (19) which is integrally formed within the front part of the toilet body, and the ventilation blower (20) exhausts the contaminated air through an opening into the waste passageway of the toilet for venting through the drain vent (16) of a conventional drain line (13). A damper (23) is provided at the exhaust output of the ventilation blower (20) to prevent back flow of sewer gases through the ventilation system and infiltration of fluids caused by drain line blockages or the like into the ventilation blower. The ventilation blower (20) is selectively energized as by raising and lowering of the toilet seat (3). |
