Abstract

PURPOSE: To simplify a constitution of an aeration passage for a cold air circulation, provide one damper device and reduce the cost by a method wherein a refrigeration chamber is formed at an upper part of a freezing chamber, a vegetable chamber is formed below the freezing chamber, cold air which has been sent to the refrigeration chamber is sent to the vegetable chamber through a return passage for the refrigeration chamber, and at the same time a part of the cold air passing through the refrigerating chamber air blowing passage is branched to the refrigerating chamber return passage.
CONSTITUTION: As a temperature within a freezing chamber 24 shows a predetermined abnormal temperature, a compressor is energized and at the same time a fan device 29 is energized. Then, a part of the cold air cooled by a cooling device 30 is sent to a refrigerating chamber transporting passage 33 and a part of it is branched in the middle part, almost of all the cold air are sent into the refrigerating chamber 25 to cool an interior part of the refrigerating chamber 25, thereafter the cold air flows into a refrigerant chamber return passage 35. Then, the cold air flowed into the refrigerating chamber return passage 35 is mixed with cold air supplied from the branch passage 37 to cool a vegetable chamber 26. The cold air is returned back into the cooling device chamber 28 through the vegetable chamber return passage 36 and cooled again by the cooling device 30. As the refrigeration chamber 25 and the vegetable chamber 26 are cooled down to a predetermined closing set temperature with the circulating cold air, the damper device 34 is closed to terminate the cooling operation.
