Abstract

본 발명은 냉장실 온도제어 조절방식의 냉장고에서 주위온도의 변화에 관계없이 냉동실의 설정온도가 유지되도록 한 냉장고의 온도조절 방법 및 장치 관한 것이다.The present invention relates to a method and apparatus for controlling a temperature of a refrigerator in which a set temperature of a freezer is maintained regardless of a change in ambient temperature in a refrigerator controlled by a refrigerator room temperature control system.

본 발명은 냉장실 온도기준 제어방식에 의해서 냉장고의 운전을 수행함에 있어 압축기의 구동에 의해 냉장실의 온도가 설정온도에 도달한 때에 냉동실에 별도로 장착된 온도감지 센서를 통해서 냉동실의 온도를 체크하여 만일 냉동실이 설정온도 이하인 때에는 냉장고의 운전을 정지시키고, 이와달리 설정온도에 비해서 높은 것으로 판명된 때에는 냉장실로 향하는 냉기유로상에 형성된 댐퍼를 폐쇄시켜 냉장실로의 냉기흐름을 차단한 상태에서 냉동실만에 대한 선택적인 냉각이 이루어지도록 하여 냉동실이 그 설정온도에 도달하게 되면 냉장고의 운전을 중지함으로써 냉동, 냉장실 각각이 그 설정온도롤 유지되도록 구성된다.In the present invention, when the temperature of the refrigerating compartment reaches a predetermined temperature by driving the compressor, the temperature of the freezing compartment is checked through a temperature sensor separately installed in the freezing compartment, When the temperature is found to be higher than the set temperature, the damper formed on the refrigerant flow path to the refrigerating compartment is closed to block the flow of cold air to the refrigerating compartment, When the freezing chamber reaches the set temperature, the operation of the refrigerator is stopped so that each of the freezing and refrigerating chambers is maintained at the set temperature.

본 발명의 냉장고 온도조절 방법은 주위온도가 내려가는 경우에는 냉동실의 온도가 항상 설정온도를 유지함에 따라 냉동실 저장식품을 안정적으로 보관할 수 있는 이점이 있다.The refrigerator temperature control method of the present invention is advantageous in that, when the ambient temperature is lowered, the temperature of the freezer compartment always maintains the set temperature, and thus the stored food in the freezer compartment can be stably stored.
