[0039] Figure 1 It is a structural schematic diagram of a refrigerator of the utility model. Figure 2 yes Figure 1 Enlarged view of point A in the middle. Figure 3 It is an exploded schematic diagram of a refrigerator of the utility model.

[0040] See also Figures 1 to 3 The present embodiment provides a refrigerator for storing items at low temperatures. The refrigerator may also be a refrigerated display cabinet, a refrigerated wine cabinet, or a cold storage cabinet. The refrigerator includes a box body 100, an inner liner (not shown) disposed in the box body 100, a door 200 rotatably covered on the box body 100, and a refrigeration assembly disposed in the box body 100. A top cover 300 is disposed at the top of the box body 100, and a display control module 400 is disposed on the top cover 300. The display control module 400 can display the storage parameters of the refrigerator, and the operation mode and parameters of the refrigerator can be set on the display control module 400.

[0041] A refrigeration chamber with an opening at the front is formed in the inner container, and articles are placed in the refrigeration chamber to store the articles at a low temperature. The door 200 is openable and closable and covers the front side of the box body 100, so that the refrigeration chamber in the box body 100 can be opened or closed, and articles can be taken in and out of the refrigeration chamber. In this embodiment, the door 200 is rotatably covered on the front side of the box body 100 to open and close the inner container.

[0042] The refrigeration assembly transfers cold energy to the air in the air duct assembly, providing cold air to the refrigeration compartment, so that the refrigeration compartment can obtain cold air. The air duct assembly can selectively penetrate the refrigeration compartment to introduce the air in the air duct assembly into the refrigeration compartment, so as to cool the refrigeration compartment.

[0043] In some embodiments, the refrigeration compartment includes a refrigerator compartment and a freezer compartment, and the air duct assembly can transport cold air to the refrigerator compartment and the freezer compartment respectively, so that the air in the air duct assembly can transfer cold air to the refrigerator compartment and the freezer compartment respectively to maintain a refrigerated environment in the refrigerator compartment and the freezer compartment.

[0044] A foam layer is provided between the inner liner and the box body 100 , and the foam layer is filled with foam material. The foam material surrounds the upper and lower, left and right and rear side walls of the refrigeration compartment, thereby insulating the refrigeration compartment and maintaining the temperature of the refrigeration compartment.

In this embodiment, the evaporator is arranged in the freezer.

[0047] The air duct assembly and the refrigeration room are connected so that air circulates between the air duct assembly and the refrigeration room, thereby transferring the cold in the air duct assembly to the refrigeration room and transferring the heat in the refrigeration room to the air duct assembly. The low-temperature and low-pressure liquid refrigerant in the evaporator is converted into a low-temperature and low-pressure gaseous refrigerant after heat exchange with the air duct assembly. The low-temperature and low-pressure gaseous refrigerant in the evaporator is transferred to the compressor and compressed into a high-temperature and high-pressure gaseous refrigerant in the compressor.

[0048] The high-temperature and high-pressure gaseous refrigerant in the compressor is transported to the condenser, where it releases heat to the outside environment, thereby converting the high-temperature and high-pressure gaseous refrigerant into a low-temperature and high-pressure liquid refrigerant. The low-temperature and high-pressure liquid refrigerant is converted into a low-temperature and low-pressure liquid refrigerant through the throttling and decompression effect of the capillaries. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator and the air in the air duct assembly for heat exchange.

[0049] The specific structure and connection relationship of the refrigeration assembly refer to the refrigeration assembly in the related art and will not be described in detail here.

[0050] The air duct assembly is disposed in the box 100 and can provide cooling to the refrigeration compartment.
