发明名称 Control system for pump operated plumbing fixtures
摘要 A plumbing fixture includes a receptacle for receiving waste, a tank for storing water, and an electrically operated pump that conveys water from the tank into the receptacle to flush the waste through a drain. The duration that the pump in operated to flush the waste is altered in response to variation of the electrical voltage supplied to the plumbing fixture. The pump is operated to decrease the amount of water in the tank when that amount is sensed to be excessive. Further operation of the pump is inhibited for a given interval to avoid overheating when the pump has been operating too frequently. The pump is cycled on and off in predefined patterns to indicate different malfunctions to a user.
