Description
E03D covers water-closets, urinals, and associated flushing mechanisms that control water discharge for sanitary purposes. This subclass includes the structural design of toilet bowls and urinal fixtures, along with the specialized valves and control systems that regulate water flow during the flush cycle. Patents in this area typically address innovations in valve actuation (mechanical, pneumatic, or electronic), water efficiency mechanisms, and the integration of flushing hardware with sanitary fixtures themselves.
