ABSTRACT:
A toilet assembly which includes a toilet stool having a ventilation conduit disposed adjacent to the back wall portion of the toilet stool for ventilating objectionable odor from a toilet bowl, the ventilation conduit extending annularly around a siphon conduit at the point where they communicate with a sewer discharge line, a fan member disposed in the lower portion of the ventilation conduit, a toilet holding tank having a motion sensor disposed on the front exterior of the toilet holding tank and free of interference from the opening and closing of a toilet seat cover, and an U-shaped gas exhaust duct disposed in the toilet holding tank and connected to the ventilation conduit for allowing exhaust gas to flow from a flush ring to the ventilation conduit, whereby upon opening the toilet seat cover, while the user sits on the seat ring, the motion sensor is actuated to operate the fan member and the objectionable odor is ventilated, and in turn when the user stands and flushes the toilet assembly, the motion sensor is deactivated and simultaneously the flush water discharges the waste product and associated objectionable odor directly to the sewer discharge line.
