ABSTRACT:
Air is removed from the vicinity of a toilet bowl of conventional design by means of a ventilation system comprising a toilet seat having an internal channel that conveys air through the hinge mechanism of the seat to an exhaust fan. The hinge mechanism is comprised of paired units, each utilizing interengaged threaded hollow tubes and right angle fittings to establish passageway between the channel of the seat and downstream air-conveying components.
