PROBLEM TO BE SOLVED: To provide an electric refrigerator in which the heat of a defrosting heater is not concentrated to the lower part of an evaporator at the time of defrosting the evaporator and the defrosting heat is prevented from leaking in the refrigerator. SOLUTION: An electric refrigerator comprises a cold air passage opening/ closing plate 16 which closes a cold air supply passage 10 for supplying cold air from an air supply fan 9 to a refrigerator during defrosting, an opening part 19c which closes in a position deviated from a cold air outlet port 20 and a bypass duct opening/closing plate 15 which closes a freezing chamber return passage 12 of cold air from the refrigerator and opens a bypass duct 14 for recirculating air supplied from the air supply fan 9 to the lower part of an evaporator 7. Air heated by a defrosting heater 8 is recirculated to the lower part of the evaporator 7 through the bypass duct 14 by the air supply fan 9, the evaporator 7 is uniformly heated by forced convection and the leakage of the heated air to the refrigerator is prevented. |
