The three

cases

100, 200, 300 have an assembled and disassembled state. In other embodiments of the present invention, the number of the boxes may be designed according to requirements, for example: the refrigerator may include only two cases, or may include more than three cases.

When the refrigerator in this embodiment is in an assembled state, the three

cases

100, 200, and 300 are stacked and assembled in the height direction, and specifically, the first case 100, the second case 200, and the third case 300 are sequentially disposed from bottom to top.

Referring to fig. 2 and 3, in the present embodiment, a first communication port 1 is provided at the top of the first casing 100 located at the lower layer, and a second communication port 2 is provided at the bottom of the second casing 200 located at the upper layer. When the second casing 200 is stacked and assembled on the top of the lower casing 100, the first communication port 1 and the second communication port 2 are in butt joint to communicate the accommodating compartments of the first casing 100 and the second casing 200. The stacking assembly relationship of the second casing 200 and the third casing 300 in the present embodiment can refer to the assembly relationship of the first casing 100 and the second casing 200, and will not be described in detail. After the refrigerators are assembled in a stacked mode, air circulation between the containing chambers is achieved between the two adjacent refrigerator bodies from top to bottom through the first communicating port 1 and the second communicating port 2, and therefore cold energy in the refrigerators is transferred.

The refrigerator also has a disassembly state, when the refrigerator is in the disassembly state, at least one pair of vertically adjacent refrigerator bodies are separated, and the first communication port 1 of the lower-layer refrigerator body and the second communication port 2 of the upper-layer refrigerator body are automatically closed after separation. Specifically, in this embodiment, the first casing 100 and the second casing 200 and the third casing 300 are separable from each other, and the separated casings can be easily handled with respect to the refrigerator assembled in a stacked manner.

In the present invention, the refrigeration assembly includes a first refrigeration unit 400, the first refrigeration unit 400 is disposed in the first box 100 at the bottom layer, and when the refrigerator in an assembled state operates, the first refrigeration unit 400 refrigerates the accommodating chamber of the first box 100 and can transfer cold energy to the accommodating chamber of the second box 200 through the first communication port 1 and the second communication port 2 which are in butt joint.

In this process, the first communication port 1 at the top of the second box 200 and the second communication port 2 at the bottom of the third box 300 are both automatically closed, so that the first box 100 and the second box 200 at the lower layer can continue to be refrigerated by the first refrigeration unit 400; meanwhile, the third casing 300 can maintain a better sealing state to prevent leakage of the original cool air inside the receiving compartment. It is understood that the second casing 200 of the present embodiment may be detached from the top of the first casing 100 for separate use.
