Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

The utility model will be further described below in conjunction with specific embodiments, but not as a limitation of the utility model.

Fig. 1 is a side view structural schematic diagram of an insulated refrigerator provided in an embodiment of the present utility model. As shown in Figure 1, the thermal insulation refrigerator provided in the embodiment of the present utility model comprises: insulation box 1, refrigerator 2 and evaporator (not shown in the figure), refrigerator 2 is located in insulation box 1, and its The side walls are respectively offset against the corresponding side walls of the incubator 1, an air supply slot 3 is formed between the top plate of the refrigerated box 2 and the top plate of the incubator 1, and a return air slot 4 is formed between the bottom plate of the refrigerated box 2 and the bottom plate of the incubator 1. The evaporator is arranged on the outside of the incubator 1, and its air supply port communicates with one end of the air supply slot 3 through a pipeline, and its air return port communicates with one end of the return air slot 4 through a pipeline. The air supply hole 5, in the present embodiment, the bottom plate of the refrigerator 2 is provided with a plurality of first return air holes 6, and the two ends of the air supply hole 5 communicate with the inside of the air supply groove 3 and the refrigerator 2 respectively, the first return Both ends of the air holes 6 communicate with the inside of the return air slot 4 and the refrigerator 2 respectively. In this embodiment, the air supply holes 5 are arranged in a rectangular array, and the air supply holes 5 relatively close to the evaporator are connected to those relatively far away from the evaporator.
