Abstract
A toilet ventilation system which ventilates the air within the bowl of a water closet, deodorizes it, adds air freshener and returns it to the toilet bowl. The system may also serves as a room air freshener and/or a comfort heater for warming the air within the toilet bowl. The system may be equipped to run on AC, DC, or both. The system has four interconnecting modules: a) a ventilator module located beneath the toilet seat, b) a central module which contains the ductwork to connect all of the other modules and the control panel for operating all of the functions of the system, c) a main blower module which contains the centrifugal fan which recirculates the air and filters which deodorize and add fragrance to the air, and d) a heater module which contains an air heater and a centrifugal fan for warming the air beneath the toilet seat.
