PROBLEM TO BE SOLVED: To prevent a thermal insulating material from entering an air passage by a method wherein a refrigeration chamber torturing air passage for returning cold air sent to a storing chamber back to a cooler and a vegetable chamber discharging air passage for feeding cold air to a vegetable chamber are integrally assembled by a cover of the cooler. SOLUTION: Cold air cooled by a cooler 10 is partially sent by a blower from a freezing chamber discharging port into a freezing chamber, cools the inner area of the chamber, thereafter the air returns back from the freezing chamber suction port to the cooler 10. In addition, residual cold air passes through the storing chamber discharging air passage and is sent to the refrigeration chamber, cools the inner area of the chamber, thereafter returns back to the cooler 100 through a refrigeration chamber returning air passage 32 integrally assembled with the cover of the cooler. Further, the cold air branched at the midway part of the refrigeration chamber returning air passage and sent to the vegetable chamber through the vegetable chamber discharging air passage 33 integrally assembled to the cover 29 of the cooler cools the chamber, thereafter returns to he cooler 10 through the vegetable chamber returning air passage. In this way, since the air passage 33 and the air passage 32 are integrally assmbled by the cover 29, it is possible to prevent a thermal insulating material from entering the device. |
