Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the refrigerator fan impeller for improving air pressure and air volume provided by the present utility model includes an impeller base 1. One side of the impeller base 1 facing the long blades 2 and short blades 3 bulges outwards in the middle, and the outer periphery of the protruding part on the impeller base 1 is of an arc structure. There are seven long blades 2 and seven short blades 3 arranged on the impeller base 1. Both the long blades 2 and short blades 3 are of arc structures. The seven long blades 2 and seven short blades 3 are alternately distributed in a ring on the impeller base 1. One end of the long blade 2 extends towards the protruding part on the impeller base 1 and contacts it, and the end of the long blade 2 extending towards the protruding part on the impeller base 1 is of an inclined structure. One end of the short blade 3 extends towards the protruding part on the impeller base 1 and does not contact it, and the end of the short blade 3 extending towards the protruding part on the impeller base 1 is of a vertical structure. A stabilizing ring 4 is arranged on the outer peripheral sides of several long blades 2 and short blades 3.
