Ventilated toilet

A ventilated toilet comprising:

• a toilet bowl having at least one hole disposed around a rim of the toilet bowl for discharging water into the toilet bowl;
• a holding tank for containing a volume of water sufficient to cause the toilet to flush when the volume of water is discharged into the toilet bowl;
• a flush mechanism for flushing the toilet, the flush mechanism controlling a flush valve that covers a drain in a bottom of the holding tank;
• a refill mechanism for refilling the holding tank;
• a water feed conduit connecting the drain to the at least one hole disposed around the rim of the toilet bowl;
• a motion-sensitive switch connected to a movable portion of the flush mechanism for controlling an air ventilation fan, the fan drawing malodorous air from the toilet bowl through the flush holes and the conduit and then drawing the malodorous air out of the toilet through an air outlet in the toilet bowl;
• and
• an air exhaust pipe in fluid communication with the drain to enable malodorous air from the toilet bowl to be drawn through the air exhaust pipe, wherein the air exhaust pipe has an upwardly sloped inlet portion that slopes upwardly from a point below the drain to inhibit water from flowing up into the air exhaust pipe, wherein a bottom end of a wall of the drain extends downwardly partially beyond a top of an opening end of the air exhaust pipe.

A fan adaptor for retrofitting a toilet to convert the toilet into a ventilated toilet, the adaptor comprising:

• an adaptor body adapted to be disposed between a rear portion of a toilet bowl and a holding tank;
• a flush valve subassembly having a drain and an upright pipe adapted to extend into the holding tank, the upright pipe being adapted to convey water from the holding tank to the drain;
• and
• an air exhaust pipe in fluid communication with the drain to enable malodorous air from the toilet bowl to be drawn through the air exhaust pipe, wherein the air exhaust pipe has an upwardly sloped inlet portion that slopes upwardly from a point below the drain to inhibit water from flowing up into the air exhaust pipe, wherein a bottom end of a wall of the drain extends downwardly partially beyond a top of an opening end of the air exhaust pipe.
