Fig. 1 is a schematic structural diagram of a combined refrigerator according to an embodiment of the present invention.

The embodiment provides a combination refrigerator, including:

at least two modular refrigerators 100, each modular refrigerator 100 having at least one compartment and a refrigeration system for providing refrigeration to the compartments; one of the compartments is set as a target compartment;

It should be noted that each compartment of the modular refrigerator 100 may be a freezing compartment, a refrigerating compartment, or a temperature-changing compartment, and a temperature detection device is disposed in each compartment to collect real-time temperature in each compartment and send the real-time temperature to the controller 200. When the modular refrigerator 100 has only one compartment, the compartment is a target compartment, and of course, each of the modular refrigerators 100 may have 2 or more compartments. Illustratively, the target compartment of each of the modular refrigerators 100 is a freezer compartment.

Illustratively, as shown in fig. 2, the combination refrigerator further includes an operation panel 300, and the set temperature of each compartment of each modular refrigerator 100 may be set by a user on the operation panel 300. Wherein, the combined refrigerator commonly adopts one operation panel 300, and the controller 200 and the operation panel 300 can be integrated on any one modular refrigerator 100 of the combined refrigerator. Each modularization refrigerator 100, controller 200 and operating panel 300 all are equipped with wifi module 400, but interconnect between the two, and wifi module 400 on the controller 200 is connected with integrated wifi module 400 on the refrigerator, transmits the control signal that controller 200 sent, and integrated wifi module 400 is connected with integrated wifi module 400 on the refrigerator to operating panel 300 integrated wifi module 400. The operation panel 300 may be provided with n operation modes, n is the number of the modular refrigerators 100 included in the combination refrigerator, the operation panel 300 may set or display the set temperature of each compartment of the corresponding modular refrigerator 100, for example, M1 on the operation panel 300 corresponds to the first modular refrigerator 100, M2 corresponds to the second modular refrigerator 100, and so on, the set temperature setting or real-time temperature display when the first modular refrigerator 100 operates may be performed by the M1 mode, the set temperature setting or real-time temperature display when the second modular refrigerator 100 operates may be performed by the M2 mode, and so on.

It should be noted that the operation state of the modular refrigerator can be divided into various types, such as a first power-on state, a stable operation state and a defrosting recovery period state. The stable operation state refers to a state when the power or the temperature of the modular refrigerator is stable, and the defrosting recovery period state refers to a state from the end of defrosting to the time of recovering normal refrigeration.
