The center beam 330 is located between the refrigerator box liner 310 and the freezer box liner 320, and is connected to the refrigerator box liner 310 and the freezer box liner 320. Exemplarily, the refrigerator box liner 310 is arranged above the freezer box liner 320. The refrigerator box liner 310 is formed with a refrigeration space 311, and it can be understood that the refrigeration space 311 is used to accommodate items that need to be refrigerated. The freezer box liner 320 is formed with a freezing space 321, and it can be understood that the freezing space 321 is used to accommodate items that need to be frozen.

[0046] See also Figure 3 The freezing air duct 400 can be arranged at the back of the freezing chamber 320. An evaporator is arranged in the freezing air duct 400, and the evaporator is used to exchange heat with the nearby air to cool the nearby air. For example, a fan is also arranged in the freezing air duct 400 to accelerate the flow of the internal air.

[0047] The air duct assembly 500 includes an air supply duct 510 and a refrigeration duct 520. The air supply duct 510 is arranged in the box body 100 and is located between the refrigeration box 310 and the freezing duct 400, for example, it is arranged at the rear of the box duct assembly 300. The refrigeration duct 520 is installed on the refrigeration box 310 and is located outside the refrigeration space 311. The refrigeration duct 520 includes an air inlet and an air outlet that are connected. The two ends of the air supply duct 510 are respectively connected to the air inlets of the freezing duct 400 and the refrigeration duct 520, and the cold air in the freezing duct 400 is sent to the refrigeration duct 520 through the air supply duct 510. The air outlet of the refrigeration duct 520 is connected to the refrigeration space 311, and the refrigeration duct 520 is used to send cold air to multiple areas of the refrigeration space 311. The air supply duct 510 and the refrigeration duct 520 are integrally formed.

[0048] The air duct assembly 500 further includes a return air duct 530, the two ends of which are respectively connected to the freezing air duct 400 and the refrigerating space 311, and the hot air in the refrigerating space 311 is sent back to the freezing air duct 400 through the return air duct 530. The return air duct 530, the air supply air duct 510 and the refrigerating air duct 520 are, for example, integrally formed.

The protrusion is inserted into the slot to connect the first shell 501 with the second shell 502. Through the above arrangement, the sealing of the connection between the first shell 501 and the second shell 502 can be improved, the air leakage of the air duct assembly 500 can be prevented, and the quality of the refrigerator 10 can be improved.

[0052] In the actual installation process of the refrigerator 10, for example, the box liner assembly 300 is installed in the box body 100, and then the freezing air duct 400 is installed behind the freezing box liner 320, and then the integrated air duct assembly 500 is installed on the box liner assembly 300 and the box body is foamed, and finally the door body 200 is installed on the box body 100. Compared with the existing refrigerators that need to first install the refrigeration air duct in the refrigeration box liner and then install the return air duct, the refrigerator 10 of the present application integrates the refrigeration air duct with the return air duct, reduces one assembly step, and improves the production efficiency of the refrigerator.

[0053] The air duct assembly 500 and the refrigerator 10 provided in the embodiment of the present application reduce the number of parts of the air duct assembly compared with the existing refrigerators by arranging the refrigeration air duct 520 outside the refrigeration space 311 and integrating the refrigeration air duct 520 with the air supply air duct 510 and the return air duct 530, and eliminates the materials such as the air duct cover, thereby reducing the production and material costs. In addition, the assembly steps of the refrigerator are reduced, which can improve the production efficiency.
