Technical Field

The invention relates to the technical field of refrigeration, in particular to a refrigeration appliance.

Background

Air-cooled refrigeration utensil contains the air outlet and the return air inlet in wind channel usually, and when refrigeration utensil was opened, the external hot gas flow that contains vapor got into, can lead to frosting in the wind channel, blockking up return air inlet or air outlet, influences the refrigeration effect, and frosting back in the wind channel, is difficult to get rid of, has influenced and has used and experienced.

Particularly, the problem of frosting is particularly obvious at the air return port, because the air inlet is always in an air outlet state, external hot air flow is not easy to enter, and when the door body of the refrigeration appliance is opened, the external hot air flow is sucked into the air return port and even into the evaporator, so that the problem of frosting is more obvious. The invention aims to solve the problem that the freezing in the air duct and the evaporator of the refrigeration appliance is prevented, and the normal use of the refrigeration appliance is not influenced.
