Patent ID: 7971443

Claim:
A refrigerator including at least one storage compartment for keeping a storage material in cold storage, comprising: a temperature switching compartment that can switch an internal temperature thereof, by cooling with a cooler and by heating with a heater, to a low temperature side at which the storage material is kept in cold storage and to a high temperature side at which cooked food is kept warm, wherein a capacity of said heater in a period during which temperature increases from the low temperature side to the high temperature side is larger than a capacity of said heater in a period during which temperature is kept at the high temperature side; a first detector for detecting the internal temperature of said temperature switching compartment; and a second detector provided next to said heater for detecting temperature in a neighborhood of said heater, wherein the capacity of said heater is changed based on the detection result of said first detector; and said heater stops when a detection temperature of said second detector is larger than a predetermined temperature.
