APPARATUS FOR CONTROLLING COLD AIR SUPPLY IN REFRIGERATOR

摘要

PURPOSE: An apparatus for controlling cold air supply in a refrigerator is provided to prevent weak cooling by increasing an amount of cold air supplied to a freezing chamber, thereby improving the cooling efficiency. CONSTITUTION: A main body(1) is divided into a freezing chamber(10) and a refrigerator compartment(20) by a separation wall, having a cooling device for generating cold air required for cooling the freezing chamber and the refrigerator compartment. A cold air supply control member(30) is mounted in a cold air guide passage(15) guiding the cold air generated from the cooling device into the refrigerator compartment, and rotates centering around a central axis for controlling an amount of cold air supplied to the refrigerator compartment. The cold air supply control member includes a damper plate having the same outer diameter as the inner diameter of the cold air guide passage, a rotary shaft forming a central axis of the damper plate, and a rotary plate rotating the damper plate.
