Inventors:

Martin Collins - Greenville MI

Assignee:

White Consolidated Industries, Inc. - Cleveland OH

International Classification:

F25D 2106

US Classification:

62156, 62234

Abstract:

Adaptive defrost control and method for a household refrigerator wherein a defrost interval is adjusted based upon the time it takes for a previous defrost cycle to complete. The adaptive defrost control also provides a vacation mode in which the defrost interval is set to an artificially long interval if a door of refrigerator has not been opened for some predetermined period of time. Further a defrost termination thermostat is provided that is stable during power interruption. The termination thermostat is used as a memory device to determine whether a defrost cycle was in process when power was interrupted.

International Classification:

F25D 2106

US Classification:

62156, 62275

Abstract:

Adaptive defrost control and method for a household refrigerator wherein a defrost heater is prevented from being powered as long as a compressor is running. The adaptive defrost control also provides a vacation mode in which the defrost interval is set to an artificially long interval if a door of refrigerator has not been opened for some predetermined period of time.

Appl. No.:

10/730610

Inventors:

Martin Collins - Greenville MI, US

Assignee:

Electrolux Home Products, Inc. - Cleveland OH

International Classification:

F25D 2106

US Classification:

62156, 62 80, 62155, 62234

Abstract:

A method for defrosting a household refrigeration appliance including a compressor and a defrost heater. After a controller indicates that it is time for a defrost cycle, the compressor is operated if the temperature of the appliance is greater than a set temperature. The compressor is stopped when a temperature of the appliance is equal to or less than the set temperature. After the step of stopping, the temperature of the appliance is raised while the defrost heater is inactivated. After the temperature is raised, the defrost heater is energized. The controller pauses for a drip time after deenergizing the defrost heater before allowing the compressor to run.
