ABSTRACT:
A ventilated toilet having a unique air duct and water trap system which results in improved ventilation for removing air contaminated with objectionable odors directly to a sewer line is disclosed. The toilet bowl and tank have built in air systems and the toilet seat is hollow and forms part of the air system. The fan and electrical components are located at the highest level of the fan-duct system so that water entering the air system due to tank overflow or a leak in the system will run out through the duct system before reaching the electrical components. The present system provides a water trap/air vent combination which does not rely on running water to refill the trap.
