Title
(EN) Air duct system of frost-free refrigerator and control method thereof
(ZH) 一种无霜冰箱的风道系统及其控制方法
Abstract
(EN)
The invention relates to the technical field of refrigerators, in particular to an air duct system of a frost-free refrigerator and a control method thereof. The air duct system of the frost-free refrigerator comprises an air supply duct system, an air return duct system, an air flow circulation motor (2) and an electronic control air door (10), wherein the air flow circulation motor (2) is arranged in a freezing chamber of the refrigerator, and the electronic control air door (10) is positioned on the air return duct system. The control method comprises that: cold air subjected to heat exchange through an evaporator chamber (3) in the freezing chamber of the refrigerator allocates air flow through an air cavity by air draft through the air flow circulation motor (2), then is respectively delivered to the freezing chamber and a refrigerator chamber of the refrigerator for heat exchange through the air supply duct system, and finally returns to the evaporator chamber (3) in the freezing chamber of the refrigerator through the air return duct system. The air duct system can ensure the unobstruction of an air supply duct, ensure no influence on the overall appearance design of the air duct, and ensure no influence on the performance and function of the air duct system.
