ABSTRACT:
An electric deodorizer for water closets is disclosed which includes an air duct entering the water tank so as to draw odorous air from the toilet bowl via the water tank overflow duct, an air blower to establish the odorous air flow, and a control means which is responsive to the change in operating characteristics of the air blower when the toilet is flushed, so as to automatically terminate the deodorization.
