PURPOSE:To diminish noise and avoid uneven distribution of coldness in freezing and refrigerating compartments and a reduction in refrigerating performance by a method wherein a fan is enclosed in a cooler cover and the periphery part of a hole in the cooler cover, which surrounds the fan, has a thickness larger than that of the adjacent part. CONSTITUTION:The cold air is generated by a cooler 4 and discharged by a fan 6 through a hole 19 in a cooler cover 18. The cold air is distributed to an air port 15 and air outlets 13 by a protruding rub 10 on the cooler cover 18 and respectively led to and circulated through refrigerating compartment and a freezing compartment where heat exchange takes place. After that, the wet air is induced by the fan 4 and turned to cold dry air by heat exchanging while it flows through the cooler 4 from bottom to top. The hole 19 is provided in the cooler cover 18 so as to surround the fan 6 and its periphery part has a flange-like shape and a thickness thicker than the adjacent part. Therefore, as the periphery part has a larger mass and is enhanced in rigidity, the periphery part of the hole 19 provided on the cooler cover 18 is prevented from vibrating and producing noise. Moreover, as a clearance is prevented from being created between the protruding rib 10 and a contact face 17 of a grille 12, problems such as uneven distribution of coldness in the freezing and refrigerating compartments and a reduction in the refrigerating performance do not occur. |
