PURPOSE:To achieve a fair finish in thawing frozen food in a refrigerator with a thawing device even when the weight and shape of the food vary, and keep the food fresh in an atmosphere suitable for preserving fish and meat even when the food is left in the thawing device after thawing. CONSTITUTION:Two or more temperature sensors 30 and 31 are in heat- conductible close contact with a bottom plate 26, and the first step is defined as a time period required for one of the temperature sensors 30 and 31 to rise up to a specified temperature. A controller controls the energizing time period and energizing ratio that are automatically determined according to the time period of the first step, a finish setting input, and a temperature difference between the two temperature sensors 30 and 31. |
