Abstract

본 발명은 냉장고의 냉기제어방법에 관한 것으로, 종래에는 냉동실과 냉장실에 냉기를 동시에 공급함으로써 냉장실에 부분적인 과냉 현상이 발생되는 문제점이 있었다.The present invention relates to a method for controlling a cold air of a refrigerator. In the related art, a partial supercooling phenomenon occurs in a refrigerator compartment by simultaneously supplying cold air to a freezer compartment and a refrigerator compartment.

이러한 점을 감안하여 본 발명에서는 냉장실의 온도를 검출하여 설정된 온도와 비교함에 따라 냉기공급을 제어함으로써 냉장실의 온도를 균일하게 유지하여 이동효율을 향상시킬 수 있다.In view of this point, in the present invention, the temperature of the refrigerating chamber is uniformly maintained by detecting the temperature of the refrigerating chamber and controlling the supply of cold air according to the set temperature.
