Abstract

본 발명은 냉장고 냉동실의 제어방법에 관한 것으로, 종래의 냉장고는 제상과 냉동실의 온도제어를 하는데 있어서, 각각의 따로 설치된 센서를 이용함으로, 냉장고의 조립생산시 부품수의 증가와 더불어 공정수가 증가하게 되고, 생산비가 증가되는 문제점이 있었으며, 이러한 문제점을 해결하기 위하여 냉동실의 냉동센서를 없애고, 증발기에 설치되어 있는 제상센서에 의한 냉동실의 제어방법으로서, 냉동실의 냉동센서가 아닌 제상센서를 이용하여 냉동실에 설정된 온도를 제어하게 되며, 냉동센서가 필요없게 되어 냉장고의 조립생산시 부품수와 공정수가 절감됨과 더불어 생산비가 절감되는 효과가 있다.The present invention relates to a method for controlling a refrigerator freezer, and in the conventional refrigerator to control the temperature of the defrost and the freezer, by using a sensor installed separately, the number of processes increases with the increase of the number of parts during assembly production of the refrigerator. In order to solve this problem, the freezing sensor of the freezer compartment is removed and the control method of the freezer compartment by the defrost sensor installed in the evaporator is used as a control method of the freezer compartment rather than the freezing sensor of the freezer compartment. It controls the temperature set in the, there is no need for a refrigeration sensor, there is an effect of reducing the number of parts and the number of processes during the assembly production of the refrigerator and the production cost is reduced.
