[0002] A freezer is a household or commercial appliance used to refrigerate or freeze food and items. It usually uses refrigeration technology to keep the temperature at a lower level to keep the food fresh and extend its shelf life.

[0003] In the prior art, a refrigerator generally includes a box body and an air outlet opened on the inner wall of the box body, and air is output to the inside of the box body through the air outlet.

[0004] Refrigerator designs often use a relatively fixed and single air outlet layout. Although this design is simple, there is a problem of uneven cold air diffusion in actual use. Since there are "dead corners" in the flow of cold air in the box, the temperature in some areas is high, which affects the preservation of food and even causes food spoilage, which is a great inconvenience for users. Utility Model Content

[0041] The second air outlet is opened on a side of the ventilation shell facing the parallel side.

[0042] In the technical solution, because the ventilation shell is close to the inner side wall of the box body, the side of the ventilation shell facing the parallel side is directly facing the first accommodation cavity without any obstruction. Therefore, through this design, the airflow output from the second air outlet can fill the first accommodation cavity as quickly as possible.

By dividing the interior of the refrigerator into a first chamber and a second chamber, and providing independent air outlets in different chambers, more precise control of the temperature of each chamber can be achieved. This design allows the refrigerator to manage items in different chambers in layers according to their different storage temperature requirements while maintaining the overall refrigeration effect. In addition, the cold air can directly enter the first chamber and the second chamber, reducing the ineffective circulation of the cold air in the box, thereby improving the cooling efficiency. Such a design also helps to reduce energy consumption and achieve the purpose of energy saving.

[0049] In some embodiments of the present application, a step is formed upward on the inner bottom wall of the box body, and the installation box is attached to the side wall of the step; the third accommodating cavity is located above the step.

[0050] In the technical solution, the installation box fits tightly against the side wall of the step. This design not only saves space but also ensures the stability of the installation box in the refrigerator. This layout allows key refrigeration components such as the evaporator to be more compactly integrated inside the refrigerator, thereby improving refrigeration efficiency. At the same time, this also simplifies the internal structure of the refrigerator, making it easier to maintain and clean.
