REFRIGERATOR CAPABLE OF KEEPING FOODS FOR A LONG TERM WITHOUT FREEZING THE FOODS

摘要

PURPOSE: A refrigerator is provided to find an overcooling cancellation temperature of each food more exactly and keep the unfrozen food freshly for a long term.;CONSTITUTION: A refrigerator comprises a storage room, a plurality of temperature sensors(20), a cool air supply unit(40), a heating unit(50), and a controller(10). A plate is mounted in a lower surface of an inner side of the storage room. The plural temperature sensors are disposed in the storage room. A part of the plural temperature sensors is contacted with the plate. The cool air supply unit cools foods. The heating unit heats an inner part of the storage room. The controller finds an overcooling cancellation temperature by a temperature change measured in the temperature sensor, and performs a control operation in order to keep the foods at a temperature higher than the overcooling cancellation temperature.;COPYRIGHT KIPO 2010
