Abstract: A self-contained electric flushing toilet bowl in which water for flushing the bowl is automatically controlled by unique control mechanism to perform a series of cyclic operations in which the supply water to the bowl and outlet flow from the bowl will be so coordinated as to impound a volume of water in the bowl at a raised water level for use in flushing and cleaning the bowl, the control mechanism being housed in an accessible rear compartment of the bowl structure. Outlet flow from the bowl is controlled by means of a valve structure embodied in a line trap of elastomeric material connected to the bowl outlet.
