ABSTRACT:
A toilet bowl aspirating system for use in a toilet tank having an overflow tube in which a filler tube is disposed to supply water to a channel having a plurality of ports provided in a rim of a toilet bowl and through which water flows about an inner side wall of the bowl during an evacuation cycle. The aspirating system comprises a blower support member which has a tubular adapter for seating engagement over a top end of the overflow tube and extends below a top water level of a toilet tank to provide a closed chamber above the top end of the overflow tube. The blower support member has an exhaust end which is positioned above the top water level and a blower is supported in that end for drawing air from the top end of the overflow tube and the plurality of ports within the toilet bowl during a timer cycle. A filter is associated with the exhaust end to filter odors emitted therefrom and originating in the toilet bowl.
