Abstract

The invention relates to an air-cooled refrigerator and discloses an air door of a frostless refrigerator. The air door is characterized in that the air door is of a shutter type. The air door of the frostless refrigerator has a simple structure, creates a fully closed defrosting space for the refrigerator, improves the defrosting effect of the whole refrigerator and can reduce energy consumption of the whole refrigerator.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a frost-free refrigerator damper. Background technique [0002] At present, most of the air duct components of frost-free refrigerators are: injection molded air ducts or a combination of injection molded air duct cover plates and air duct foam. The shape of the air supply port and the air outlet mode of the air duct part of this structure are fixed, and are in a normally open state. In the defrosting state, if the air supply port is open, when the defrosting heating pipe is working, the hot air will rise and will be transferred to the box through the air supply port, which will affect the storage temperature. The heating tube works longer, thereby increasing energy consumption. Contents of the invention [0003] The invention aims at the defect of outflow loss of defrosting heat of a frost-free refrigerator, and provides a frost-free refrigerator air door which can be completely...
