PROBLEM TO BE SOLVED: To provide the chilled gas circulating unit for a refrigerator to eliminate the opening of the door of a deep freezing chamber even when the door of a cold storage chamber is rapidly closed. SOLUTION: A chilled gas circulating unit has first and second suction ports 50 for sucking the heated airs in a cold storage chamber 10 and deep freezing chamber 20 to an evaporator 30, and first and second suction ducts 34 communicating with the suction port 50. The first suction duct communicates with the first suction port, and is formed at a partition wall so as to provide the heated air in the chamber 10 to the evaporator 30. The second suction duct communicates with the second suction port, and is formed at a partition wall so as to provide the heated air in the chamber 20 to the evaporator 30. The first suction port has a narrow upper part and wide sectional shape of lower part, and one or more steps are formed on the oblique surface from the upper part to the lower part. |
