The refrigerating compartments 125 of the present embodiment may be divided into a plurality of compartments 125, as shown in fig. 5, and are divided into 3 refrigerating compartments 125, and three refrigerating chambers 20 are correspondingly provided, and each refrigerating chamber 20 adopts the same structure as described above.

Compared with the prior art, the embodiment has the following beneficial effects:

(1) The first air outlet 31 that first heat dissipation chamber 101 communicates sets up the other end at keeping away from first heat dissipation fan 211, the second heat dissipation chamber 102 that sets gradually with first heat dissipation chamber 101 in the direction of height passes through the heat dissipation auxiliary channel intercommunication to first air outlet 31, first heat dissipation fan 211 and second heat dissipation fan 212 are kept away from to the air-out end of first heat dissipation chamber 101 and second heat dissipation chamber 102 promptly, this heat abstractor has avoided the hot gas flow to be blown out the back again by a large amount of problems of inhaling back to the heat dissipation space, heat dissipation efficiency has been improved, the refrigeration effect of gradevin has further been improved.

(2) The first refrigeration part 52 and the second refrigeration part 54 uniformly distribute the cold energy in the refrigeration cavity 20, an air duct restraining the flowing direction of the cold air is formed by the first refrigeration fins 521 and the second refrigeration fins 543, the air is sucked into the refrigeration cavity 20 from the refrigeration air inlet 37 on the air duct cover plate 122, then is cooled by the plurality of second refrigeration parts 54 connected with the refrigeration pipes 53, part of air flow is cooled by the first refrigeration part 52, and in the cooling process, the air is uniformly blown out from the plurality of refrigeration air outlets 35, so that the uniform refrigeration in the whole room is formed.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
