Abstract

PURPOSE: To prevent a refrigerating action from being deteriorated by foods and reduce an irregular distribution of temperature by a method wherein a cold air feeding passage connected to a cold air discharging passage of a temperature adjustment device for a third chamber is arranged within a defined wall, and a case frame forming a cold air discharging passage having a plurality of cold air discharging holes and connected to the cold air feeding passage is mounted around a front surface of the third chamber. CONSTITUTION: A cold air feeding passage 19 extended to a third chamber 4 is connected to a third chamber cold air discharging passage 12, arranged in a partition wall 14. A case frame 20 opposing against a door 17 is arranged around a front surface of a third chamber 4, its upper part has a plurality of cold air discharging holes 21, and a cold air discharging passage 23 communicating with the third chamber cold air feeding passage 19 is formed by a communication port 22. Cold air controlled to a proper amount by a damper opening or closing device 10 is guided to a cold air discharging passage 23 through a cold air discharging passage 12 and the cold air feeding passage 19, cold air is supplied through a plurality of cold air discharging holes 21 toward the central part in front of an inner side of the third chamber 4, resulting in that dispersion of temperature or local freezing caused by arrangement of foods can be prevented, and concurrently, it is possible to collect irregular distribution of temperature caused by a structural aspect indicating a higher temperature at its inner front section than that of a rear part in the chamber.
