Abstract

An automatic bathroom flusher includes a flusher body, a valve assembly, an electronic control system, and a flusher cover. The flusher body includes an inlet and an outlet, and is designed to accommodate the valve assembly that controls water flow between the inlet and the outlet. The valve assembly includes a valve member movable with respect to a valve seat providing a sealing action. The bathroom flusher may include a user sensor, and one or more photovoltaic cells for supplying electrical power to the electronic control system. The bathroom flusher enables two or multiple flush volumes in automatic or manual modes, depending on a user action. The bathroom flusher may include a user interface including a button and visible LEDs.
