The drain outlet includes a venturi area into which the outlet end of the air passage defining structure opens and the normal flushing of the toilet bowl thereby causes air and odors from within the upper portion of the toilet bowl to be educted therefrom by venturi action. Also, the air passage defining structure includes an air pump serially connected therein intermediate its opposite ends and one way air valve structure also serially connected therein downstream from the air pump structure.
