Problems solved by technology
Air-cooled refrigerators are heated by heating wires during defrosting, which will cause the temperature of the air in the evaporator cavity to rise, and due to natural convection through the air outlet of the freezing air duct into the refrigeration compartment, or radiation conduction, the temperature in the refrigeration compartment will rise. Large fluctuations, which will affect the storage of food and increase the energy consumption of the whole machine

The invention provides an air way assembly of a refrigerator. The air way assembly comprises a first freezing air way, a second freezing air way and a freezing face cover. An air return air way is arranged at the rear portion of the first freezing air way and is matched with a first air inlet, a first air door and a draught fan on the second freezing air way to form an air return air way. The airreturn air way is independent from a refrigerating air way of the air way assembly of the refrigerator. Heat generated by temperature rising for evaporator chamber defrosting passes through the air return air way to go back to the lower portion of an evaporator. By means of the air way assembly of the refrigerator, heat generated during refrigerator defrosting is used for defrosting, and the phenomenon that hot air enters a refrigerating chamber and the chamber temperature is increased is avoided.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, more specifically to a refrigerator air duct assembly. Background technique [0002] With the increasing popularity of air-cooled refrigerators and air-cooled freezers, how to effectively improve the efficiency of the air duct and reduce the temperature fluctuations in the compartments has become a major issue in the refrigerator industry. Air-cooled refrigerators are heated by heating wires during defrosting, which will cause the temperature of the air in the evaporator cavity to rise, and due to natural convection through the air outlet of the freezing air duct into the refrigeration compartment, or radiation conduction, the temperature in the refrigeration compartment will rise. The fluctuation is large, which affects the storage of food and the increase of the energy consumption of the whole machine. Contents of the invention [0003] The present invention aims to solve the...
