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 ℃.

In addition, the air-cooled refrigerator 100 may further include: a heater (not shown) is disposed in the temperature-changing chamber 113 and is configured to be controllably activated to raise the temperature inside the temperature-changing chamber 113. The heat provided by the heater and the cold provided by the evaporator are matched, so that the temperature range of the variable temperature chamber 113 can reach 10 ℃ to 20 ℃. The optimal storage temperatures of different types of articles are different, and therefore the storage compartments suitable for storage are also different. For example, the fruit and vegetable food is preferably stored in the refrigerating compartment 112 or the temperature-changing compartment 113, and the meat food is preferably stored in the freezing compartment 114.
