Abstract: PURPOSE: To make the partitioning walls thin, and expand the internal capacity of a refrigerator by a method wherein return cold air from the refrigerating chamber is returned to the condenser from a suction port of the refrigerating chamber, which is located above a low temperature chamber in the refrigerating chamber and at the far end of the refrigerating chamber, through a refrigerating chamber return duct on the back part of the refrigerator. CONSTITUTION: A refrigerating chamber damper thermostat 18 is provided on the back part of a refrigerating chamber 2 of a refrigerator main body 29 to regulate the quantity of cold air to be fed by a blower 17, and the cold air is made to flow into a refrigerant chamber 2 from refrigerating chamber outlets 31 for respective stages being formed by shelves 3 which are provided in the refrigerating chamber 2, through a refrigerating chamber discharging duct 30 being provided on the back part of the refrigerating chamber 2. A refrigerating chamber suction port 32 which is provided above a low temperature chamber 13 and on the lowest stage on the back part of the refrigerating chamber 2 communicates with a lower part of a vegetable chamber 10 through a refrigerating chamber return duct 22, and the refrigerating chamber return cold air is made to flow in. Since the return cold air of the refrigerating chamber 2 flows through the refrigerating chamber return duct 22, the refrigerating chamber return duct is not required on partitioning walls, and therefore, the partitioning walls do not become thick, and the internal capacity of the refrigerator can be expanded.
