[0037] See also Figure 1 An embodiment of the present invention provides a refrigerator 100, including a box body (not shown) and a shelf assembly 20. The box body is provided with a receiving cavity (not shown), and the shelf assembly 20 is arranged in the receiving cavity for placing items (mainly food).

[0038] In one embodiment, the box body is cylindrical. It is conceivable that in other embodiments, the shape of the box body is not limited, such as the box body can also be in the shape of a cuboid.

[0039] The following takes the cylindrical box as an example to describe the technical solution of the present invention in detail. This embodiment is only used as an example and does not limit the technical scope of the present invention. Furthermore, the drawings in the embodiments also omit unnecessary components and clearly show the technical features of the present invention.

[0040] The box body includes a base 11, a box frame 12, a box door (not shown) and a box cover 13. The box frame 12 is fixedly connected to the base 11.
