ABSTRACT:
A ventilator for toilets is disclosed which includes an electrically operated blower and an exhaust conduit for withdrawing odors from the toilet bowl through the flush water distribution outlets within the bowl, and through the overflow pipe within the water tank.
Special electrically operated air valves, and special electrical controls are provided so that one central system may effectively remove emission odors from all of the toilets within a household. The combination of air valves and electrical switches provides completely independent ventilation of each toilet although only one blower is normally employed.
The special valves of this invention provide the unique function of repressurizing the water tank at the moment the toilet is flushed. A unique switching device is provided for the control of the valves.
