  • the cold air that flows onto the ice making cover 113 then flows to the cold air return flow passage together with the cold air that has circulated inside of the refrigerating chamber 101 to be returned to the inside of the heat-exchange chamber 121.
  • the cold air discharged by the auxiliary blowing fan 149 will have a relatively low temperature compared to the cold air circulating the inside of the refrigerating chamber 101. Therefore, the temperature difference between the inside of the ice making room 111 and one side of the refrigerating chamber 101 contacting the ice making room 111 may be relatively reduced, making it possible to prevent the dewing phenomenon, or accumulation of condensation, generated on the surface of the ice making housing 110, and in particular, on the surface of the ice making cover 113.
  • the cold air discharged through the auxiliary cold air outlet 147 is directed toward the front of the refrigerating chamber 101. Therefore, although the refrigerating chamber 101 may be opened by the refrigerating chamber doors 107 and 108, the cold air discharged through the auxiliary cold air outlet 147 may function as a sort of air curtain, making it possible to reduce an amount of cold air from inside the refrigerator 101 that is leaked to the external.

Therefore, dewing, or condensation, accumulated on the surface of the ice making room due to the temperature difference between the inside of the refrigerating chamber and the inside of the ice making room may be reduced.
  • the cold air circulates within the refrigerating chamber by means of a separate fan. Therefore, leakage of cold air to the outside as the refrigerating chamber door is opened and closed is reduced, making it possible to preserve foods stored in the inside of the refrigerator in a more fresh state.
  • a refrigerator is provided that can reduce a dewing phenomenon generated on the surface of an ice making room provided on a backside of a refrigerating chamber door.
  • a refrigerator is provided that can maintain the inner temperature of the refrigerator as a refrigerating chamber door is opened and closed.
