Filed:

Dec 17, 2004

Appl. No.:

11/016428

Inventors:

Otto R. Butsch - Placentia CA, US
Kevin G. Bowcutt - Aliso Viejo CA, US
Gregory Blake - Irvine CA, US
Daniel L. Corbin - Irvine CA, US
Dennis A. Repp - Newport Beach CA, US

Assignee:

Limit, Inc. - Newport Beach CA

International Classification:

E03D 11/02

US Classification:

4427, 137413

Abstract:

A toilet overflow prevention device including an overflow valve assembly, a control valve and a water level sensor. The overflow valve assembly is configured to selectively permit a flow of water through the valve assembly from the tank to the bowl of an associated toilet. The water level sensor is configured to provide a control signal in response to detecting an above-normal water level within the bowl of the toilet. The control valve is configured to actuate the overflow valve assembly in response to a control signal from the water level sensor. Preferably, the overflow valve assembly is separate from the primary flush valve of the toilet and is located between the primary flush valve and the bowl of the toilet.

International Classification:

E03D 11/02

US Classification:

4427

Abstract:

A system for preventing overflow of a toilet includes a sensor, a processor and an actuator. The sensor senses a parameter caused by fluid dynamics within the toilet during a flush cycle. The parameter may involve vibration, sound, pressure, fluid flow rate or other detectible characteristics of the toilet. The processor uses information regarding the parameter that is gathered by the sensor to evaluate the condition of the flush cycle to determine if an impeded flush condition exists. In the event of an impeded flush condition, the processor directs the actuator to close a valve, which may be the toilet flapper valve in some embodiments. Also disclosed are methods for preventing toilet overflow, detecting an impeded flush condition and calibrating the system.
