The optimal storage temperature for different types of items is not the same, and the storage compartments suitable for storage are also different. For example, fruits and vegetables are preferably stored in the refrigerating compartment 112 or the temperature-changing compartment 113 , and meat foods are preferably stored in the freezing compartment 114 .

FIG. 4 is a partial schematic view of the inner pot 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention. As shown in FIGS. 3 and 4 , the refrigerated return air duct 130 may include: a general return air duct 131 , a first sub-return air duct 132 and a second sub-return air duct 133 .
