본 발명은, 복수의 냉각실이 구비된 냉장고 및 그 구동제어방법에 관한 것으로서, 보다 상세하게는 상기 복수의 냉각실중 적어도 어느 하나의 급속냉각모드시 나머지 냉각실에 부속되는 송풍팬의 작동을 중지하고 압축기를 최대회전속도로 구동되도록 함으로써, 해당 냉각실의 급속냉각조건을 효과적으로 달성될 수 있도록 한 냉장고 및 그 구동제어방법에 관한 것이다.The present invention relates to a refrigerator having a plurality of cooling chambers and a driving control method thereof, and more particularly, to the operation of a blower fan attached to the remaining cooling chambers in a rapid cooling mode of at least one of the plurality of cooling chambers. By stopping the compressor and driving at the maximum rotational speed, the present invention relates to a refrigerator and a driving control method thereof, in which rapid cooling conditions of the cooling chamber can be effectively achieved.

냉장고는 일반적으로 비교적 저온의 냉동실과 상대적으로 고온의 냉장실을 가지며, 이들 냉동실과 냉장실내에 수용된 음식물을 냉각하기 위한 냉동시스템을 구비한다.Refrigerators generally have a relatively low temperature freezer compartment and a relatively high temperature refrigerating compartment, and include a refrigerating system for cooling the food contained in the freezer compartment and the refrigerating compartment.

일반적인 냉동시스템은, 냉매를 압축하는 압축기와, 압축기로부터 압축된 고온고압상태의 냉매를 방열을 통하여 응축하는 응축기와, 응축기로부터의 냉매를 제공받아 냉매가 증발하면서 주위의 잠열을 흡수하는 냉각작용에 의하여 주변의 공기를 냉각하는 적어도 하나의 증발기를 가진다. 또한, 냉동실 및 냉장실에는 각각 냉동실팬 및 냉장실팬이 부속되어 있으며, 이들 냉동실팬 및 냉장실팬은 해당 증발기를 통과하면서 열교환되어 냉각된 공기를 해당 냉각실을 향하여 송풍하게 된다. 냉동실 및 냉장실에는 각각의 실내온도를 검출할 수 있도록 냉동실온도센서 및 냉장실온도센서가 각각 구비된다.A general refrigeration system includes a compressor that compresses a refrigerant, a condenser that condenses the refrigerant at a high temperature and high pressure state compressed by the compressor, and a cooling operation that absorbs latent heat while the refrigerant is evaporated by the refrigerant from the condenser. Thereby having at least one evaporator for cooling the surrounding air. In addition, a freezer compartment and a refrigerating compartment fan are respectively attached to the freezer compartment and the refrigerating compartment, and these freezer compartment fans and the refrigerating compartment fans are blown through the evaporator to heat the cooled air toward the corresponding cooling compartment. The freezing compartment and the refrigerating compartment are provided with a freezing compartment temperature sensor and a refrigerating compartment temperature sensor, respectively, to detect respective indoor temperatures.

이러한 냉동시스템이 구비된 냉장고는 제어프로그램이 내장된 마이컴등에 의하여 설정된 냉동조건 및/또는 냉장조건에 따라 압축기, 냉동실팬 및 냉장실팬을 제어하여 냉동조건 및/또는 냉장조건을 달성하게 된다.The refrigerator equipped with such a refrigeration system controls the compressor, the freezer compartment and the refrigerating compartment fan according to a freezing condition and / or a refrigeration condition set by a microcomputer with a built-in control program to achieve a freezing condition and / or a refrigeration condition.

한편, 냉동실 및 냉장실중 적어도 어느 하나의 냉각실을 급속냉각하고자 할 때에는, 냉장고의 외부에 노출되도록 설치되는 조작판넬 등에 구비된 급속냉동모드스위치와 급속냉장모드스위치중 어느 하나를 선택함으로써, 해당 냉각실의 급속냉각기능을 수행하게 된다.On the other hand, if you want to rapidly cool at least one of the freezing compartment and the refrigerating compartment, by selecting any one of the quick freezing mode switch and the quick refrigerating mode switch provided on the operation panel installed to be exposed to the outside of the refrigerator, Rapid cooling of the room will be performed.

At this time, the cooling fan of the remaining cooling chamber is operated in accordance with the cooling conditions of the cooling chamber, there is a problem that the cooling efficiency of the cooling chamber to be rapidly cooled to take a relatively long time to achieve the set rapid cooling temperature conditions.

따라서, 본 발명의 목적은, 복수의 냉각실중 적어도 어느 하나의 냉각실의 급속냉각시 압축기의 회전속도를 증가시키고, 나머지 냉각실의 냉각팬의 작동을 중단하여 급속냉각기능이 강화되도록 한 냉장고 및 그 구동제어방법을 제공하는 것이다.Therefore, an object of the present invention is to increase the rotational speed of the compressor during the rapid cooling of at least one of the cooling chambers of the plurality of cooling chambers, and to stop the operation of the cooling fans of the remaining cooling chambers so as to enhance the rapid cooling function. And a drive control method thereof.
