Description

냉장고의 고내 모터 제어방법{METHOD FOR CONTROL OF MOTOR IN REFRIGERATOR}Motor control method in the refrigerator {METHOD FOR CONTROL OF MOTOR IN REFRIGERATOR}

본 발명은 냉장고의 고내 모터 제어방법에 관한 것으로서, 보다 상세하게는 간냉식 냉장고의 도어 오픈시에 외기온도 및 습도에 따라 고내 모터를 온오프하여 고내의 서리 적상을 최소화하도록 하는 냉장고의 고내 모터 제어방법에 관한 것이다.
The present invention relates to a method for controlling the internal motor of a refrigerator, and more particularly, a method for controlling the internal motor of a refrigerator to minimize frost accumulation in the refrigerator by turning on and off the motor in accordance with the outside temperature and humidity when the door of the intercooled refrigerator is opened. It is about.

일반적으로, 냉장고는 식품을 차게하거나 부패하지 않도록 저온에서 보관하기 위한 장치로 보관된 식품을 냉각하기 위한 냉각시스템을 구비한다. In general, refrigerators have a cooling system for cooling the food stored in the device for storing at low temperature so as not to chill or rot the food.

구체적으로, 냉각시스템은 압축기를 통해 압축된 냉매가 증발기를 통해 기화되면서 생성된 냉기로 냉각을 수행한다.Specifically, the cooling system performs cooling with the cold generated as the refrigerant compressed through the compressor is vaporized through the evaporator.

이러한 냉장고는 냉각방식에 따라 직냉식과 간냉식으로 구분하는데, 간냉식은 냉각팬으로 차가운 공기를 냉각선에 통과시켜 냉각시키는 방법으로 냉장고 내부에 온도가 골고루 분포되는 장점이 있는 반면 도어 오픈시 냉기가 토출되는 단점이 있고, 직냉식은 벽면을 따라 설치된 냉각기를 통해 고내 벽면을 직접 냉각시킴에 따라 도어 오픈시에도 냉기 토출이 적어 온도편차가 거의 없는 반면 벽면에 성에가 잘 생기고 바닥에 물이 고이는 단점이 있다.
These refrigerators are classified into direct cooling and intercooling according to the cooling method. In the intercooling method, the cooling fan is cooled by passing a cool air through a cooling line, and the temperature is distributed evenly inside the refrigerator. The direct cooling type directly cools the inner wall of the refrigerator via a cooler installed along the wall, so there is little temperature deviation even when the door is opened, so there is almost no temperature deviation, but frost is formed on the wall and water is accumulated on the floor.
