The embodiment provides an air-cooled refrigerator, can introduce the higher gas of humidity of cold-stored room in the alternating temperature room, promotes the indoor humidity in alternating temperature room, avoids wherein food to air-dry to promote the storing effect. Fig. 1 is a schematic structural diagram of an air-cooled refrigerator 100 according to an embodiment of the present invention, fig. 2 is a front view of an inner container 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention, and fig. 3 is a rear view of the inner container 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention. As shown in fig. 1 to 3, the air-cooled refrigerator 100 of the present embodiment may generally include: the refrigerator body 110, the door body 120 and the refrigerated return air duct 130.
The box body 110 defines a storage compartment therein, and the storage compartment includes a refrigerating compartment 112 and a temperature-changing compartment 113. Specifically, the box body 110 may include an inner container 111 and an outer casing (not shown), and an insulating layer (not shown) is filled between the inner container 111 and the outer casing. And, the inner container 111 defines the storage compartment.

Each storage compartment can be divided into a plurality of storage areas by a dividing plate, and the articles are stored by racks or drawers.
The door 120 is disposed at a front side of the cabinet 110 to operatively open and close the storage compartment. The door bodies 120 may be disposed corresponding to the storage compartments, that is, one or more door bodies 120 may be disposed corresponding to each storage compartment. The door 120 may be pivotally disposed on a front surface of the cabinet 110, and may also be opened in a drawer manner. And the refrigerated return air duct 130 is configured to be in controlled communication with the refrigerating compartment 112 and the temperature-changing compartment 113, so that the gas in the refrigerating compartment 112 at least partially enters the temperature-changing compartment 113. Because the humidity of the air in the refrigerating chamber 112 is high, the air in the refrigerating chamber 112 is introduced into the temperature-changing chamber 113, so that the humidity in the temperature-changing chamber 113 can be effectively improved, the air drying of food in the temperature-changing chamber 113 is avoided, and the storage effect is improved.
A cooling chamber 115 is further defined inside the cabinet 110, and an evaporator is provided inside the cooling chamber 115 to provide cooling energy to the storage compartment. As shown in fig. 2, the freezing chamber 114 and the cooling chamber 115 may be in a front-rear positional relationship, that is, the cooling chamber 115 is located behind the freezing chamber 114. That is, the refrigerating compartment 112, the variable temperature compartment 113, and the cooling compartment 115 are also disposed in a positional relationship from top to bottom. The evaporators provide different cooling capacities for various storage compartments, so that the temperatures in the various storage compartments are different. For example, the temperature in the refrigerated compartment 112 is generally between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature in the freezer compartment 114 is typically in the range of-22 c to-14 c. The temperature range within the temperature-changing compartment 113 is typically between 10 ℃ and 20 ℃.
