Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a refrigerator structure that can improve the volume ratio of the freezer compartment. Background Technology

[0002] Most existing refrigerators place the evaporator in the freezer compartment. This design reduces the storage space in the freezer compartment. In order to reduce the loss of cold air from the evaporator to the freezer compartment, a thicker foam layer is needed to insulate the back of the freezer compartment. However, the thicker foam layer will affect the volume ratio of the refrigerator freezer compartment, reducing the utilization rate and increasing the production cost.

[0003] In addition, when installing a built-in refrigerator, the thicker foam layer often causes the refrigerator to protrude from the surface of the furniture. However, if an ultra-thin refrigerator is used, the back of the refrigerator generally needs to use materials with better heat insulation performance to meet the cooling effect of the freezer compartment, which increases the purchase cost.

After heat exchange, the cold air enters the second main return air inlet of the return air duct through the second return air inlet on the second top plate, and finally enters the evaporator inlet in the return air duct, thus completing the cold air circulation.

[0043] Compared to traditional refrigerators, this invention installs the evaporator horizontally in the return air duct at the crossbeam between the freezer and refrigerator compartments. This solves the problem of cold loss caused by the evaporator being located in the freezer compartment, reduces the thickness of the foam layer in the freezer compartment, and lowers production costs.
