Description

Refrigerating apparatus Technical Field The invention relates to the technical field of refrigeration equipment, in particular to refrigeration equipment. Background The refrigerator, freezer and other refrigerating equipment may have functional compartments with drawers to defrost food. However, the thawing scheme in the prior art generally adopts a mode of blowing air from the upper side of the drawer to the surface of the food for thawing, and because the air flow can only blow in from the upper side of the food, the upper surface of the food is directly washed by the air flow, the thawing speed is higher, and the lower surface of the food is lower because the lower surface of the food is contacted with the bottom of the drawer, so that the thawing degree of each part of the food is obviously different, and the thawing efficiency is low and the uniformity is poor. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides the refrigeration equipment which can improve the efficiency and uniformity when thawing food.
