Automatic bathroom flushers

摘要

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.

主权项

1. An automatic bathroom flusher, comprising:
a valve having a valve body including an inlet and an outlet and a valve seat inside said body; a valve member cooperatively arranged with said valve seat, said valve member being constructed and arranged to control water flow between said inlet and said outlet, movement of said valve member between open and closed positions being controlled by water pressure inside a pilot chamber; an external cover designed for enclosing an electronic control module comprising a sensor constructed and designed to detect a user, and a controller providing signals to initiate an actuator for controlling operation of said valve by controlling said water pressure, said controller being constructed and programmed to communicate with and control operation of said sensor and execute a target detection algorithm to detect said user, said controller being constructed to initiate an automatic flush cycle after detecting departure of said user; and a photovoltaic cell, sensitive to wavelengths of visible light, for providing electrical power to a rechargeable device and said photovoltaic cell providing a signal used by said controller as supplemental data in addition to signals from said sensor for controlling operation of said valve member based on said target detection algorithm and said supplemental data.
