본 발명은 냉장고 및 그 제어방법에 관한 것으로서, 보다 상세하게는, 냉장실의 온도에 기초하여 압축기의 구동을 제어하는 냉장고 및 그 제어방법에 관한 것 이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator and a control method thereof, and more particularly, to a refrigerator and a control method thereof for controlling driving of a compressor based on a temperature of a refrigerator compartment.

냉장고는, 도 1에 도시된 바와 같이, 캐비넷(1)내에 격벽에 의해 상하로 구획된 냉각공간인 냉장실(3)과 냉동실(2)이 형성되어 있으며, 냉장실(3)의 후방 하부에는 냉매를 압축하는 압축기(18,38)가 설치되어 있다. 그리고, 냉장실(3) 및 냉동실(2)의 후방에는 고내공기를 냉각시키기 위한 냉장실증발기(7)와 냉동실증발기(6)가 설치되어 있으며, 냉장실증발기(7)와 냉동실증발기(6)의 상부에는 고내공기를 순환시켜 냉장실증발기(7) 및 냉동실증발기(6)를 통과하여 냉각되도록 하는 냉장실송풍팬(5) 및 냉동실송풍팬(4)이 설치되어 있다. As shown in FIG. 1, the refrigerator 1 includes a refrigerating chamber 3 and a freezing chamber 2, which are cooling spaces partitioned up and down by partition walls in the cabinet 1, and a refrigerant is provided at a lower rear portion of the refrigerating chamber 3. Compressors 18 and 38 for compressing are provided. A refrigerator compartment evaporator 7 and a freezer compartment evaporator 6 are installed at the rear of the refrigerating compartment 3 and the freezing compartment 2, respectively. A refrigeration chamber blower fan 5 and a freezer compartment blower fan 4 are installed to circulate the air inside the refrigerator so as to cool through the refrigerator compartment evaporator 7 and the freezer compartment evaporator 6.

한편, 냉장실(3)에는 냉장실온도를 감지하는 냉장실온도감지센서(12,32)가 설치되어 있으며, 캐비넷(1)의 외부에는 외기온도를 감지하는 외기온도센서(14,34)가 설치되어 있다. Meanwhile, the refrigerating chamber 3 is provided with refrigerating chamber temperature detecting sensors 12 and 32 for detecting the refrigerating chamber temperature, and the outside air temperature sensors 14 and 34 for detecting the outside air temperature are installed outside the cabinet 1. .

일반적으로 냉장고는, 냉동실온도에 기초하여 압축기(18,38)를 온오프 제어하며, 이에 따라, 냉장실(3) 및 냉동실(2)의 온도를 소정 설정온도로 유지하도록 설계되어 있다. 그런데, 이러한 냉동실온도에 기초하여 압축기(18,38)를 제어하는 방법은, 냉동실(2)보다 온도변화에 비교적 민감한 냉장실(3) 온도의 유지에 어려움이 있으며, 냉장실온도의 변동으로 냉장실(3)의 성능이 저하된다는 문제점이 있다. In general, the refrigerator controls the compressors 18 and 38 on and off based on the freezer compartment temperature, and is thus designed to maintain the temperatures of the refrigerating compartment 3 and the freezer compartment 2 at a predetermined set temperature. However, the method of controlling the compressors 18 and 38 based on the freezer compartment temperature is difficult to maintain the temperature of the refrigerator compartment 3 which is relatively more sensitive to the temperature change than the freezer compartment 2, and the refrigerator compartment 3 is changed due to the variation of the refrigerator compartment temperature. ), There is a problem that the performance is reduced.

이에 따라, 냉장실온도에 기초하여 압축기(18,38)의 구동을 제어하는 제어방법이 제안되어 있다. 이러한 냉장실온도에 기초한 냉장고의 제어는, 냉장실온도와, 제어부에 미리 입력된 압축기 동작개시온도와 동작종료온도를 비교하여 압축기(18,38)의 구동을 온오프하여 이루어지게 된다. Accordingly, a control method for controlling the driving of the compressors 18 and 38 based on the refrigerating chamber temperature has been proposed. The control of the refrigerator based on the refrigerating compartment temperature is performed by comparing the refrigerating compartment temperature with the operation start temperature and the end operation temperature of the compressor previously input to the control unit, thereby turning off the driving of the compressors 18 and 38.

이러한 냉장고의 운전중, 외기의 온도가 일정온도 이하로 저하되면, 냉장실온도가 미리 설정된 압축기 동작개시온도와 동작종료온도 사이에서 일정 온도를 유지하게 되며, 냉장실온도가 압축기(18,38) 동작개시온도로 상승되지 아니함에 따라, 압축기(18,38)가 오프상태를 유지하게 된다. 그런데, 이렇게 압축기(18,38)의 오프상태가 일정 시간 이상 지속되면, 냉동실(2)의 온도가 상승되게 되며, 냉동실(2)이 약냉으로 유지됨에 따라, 냉동실(2)의 성능이 저하되는 문제가 발생하게 된다. During operation of the refrigerator, when the temperature of the outside air falls below a certain temperature, the refrigerator compartment temperature is maintained at a predetermined temperature between the preset compressor operation start temperature and the operation end temperature, and the refrigerator compartment temperature starts operation of the compressors 18 and 38. As it does not rise to temperature, the compressors 18 and 38 remain off. However, when the off state of the compressors 18 and 38 is maintained for a predetermined time or more, the temperature of the freezer compartment 2 is increased, and as the freezer compartment 2 is maintained at low temperature, the performance of the freezer compartment 2 is deteriorated. Problems will arise.

따라서 본 발명의 목적은, 냉장실온도에 기초하여 압축기의 구동을 제어할 경우, 외기온도의 저하로 인해 냉동실의 온도가 일정온도 이상 상승하는 것을 방지할 수 있도록 한 냉장고 및 그 제어방법을 제공하는 것이다.Accordingly, an object of the present invention is to provide a refrigerator and a method of controlling the same, when controlling the operation of the compressor based on the temperature of the refrigerator compartment, to prevent the temperature of the freezer compartment from rising above a certain temperature due to a decrease in the outside air temperature. .

According to the present invention, there is provided a control method of a refrigerator having a freezer compartment and a refrigerating compartment, and a control unit for controlling the temperature of the refrigerating compartment to be between a predetermined compressor operation start temperature and a compressor operation end temperature. Detecting an outside temperature; Accumulating the dwell time of the compressor; When the refrigerating compartment temperature and the outside air temperature are respectively equal to or lower than the compressor operation start temperature and the lower air limit temperature, and the continuous idle time and the refrigerating chamber temperature are respectively equal to or greater than a predetermined idle limit time and the compressor operation end temperature, the inside of the refrigerating compartment to the compressor operation start temperature. Heating; When the compressor operation start temperature is reached by the control method of the refrigerator comprising the step of driving the compressor.

또한, 상기 목적은, 본 발명의 다른 분야에 따르면, 냉동실 및 냉장실을 갖는 냉장고에 있어서, 상기 냉장실의 온도를 감지하는 냉장실온도감지센서와; 외기의 온도를 감지하는 외기온도센서와; 압축기의 지속 휴지시간을 누적하는 카운터와; 상기 냉장실의 내부를 가열하는 냉장실히터와; 상기 냉장실 온도 및 외기온도가 각각 상기 압축기 동작개시온도 및 외기하한온도 이하이고, 상기 지속 휴지시간 및 냉장실온도가 각각 소정의 휴지 한계시간 및 압축기 동작종료온도 이상일 때, 상기 냉장실온도가 상기 압축기 동작개시온도까지 상승하도록 상기 냉장실히터를 작동시키고 상기 냉장실온도가 상기 압축기 동작개시온도까지 상승하면 상기 압축기를 구동시키는 제어부를 갖는 것을 특징으로 하는 냉장고에 의해서도 달성될 수 있다.In addition, the above object is, according to another field of the present invention, a refrigerator having a freezer compartment and a refrigerating compartment, comprising: a refrigerating compartment temperature sensor for sensing a temperature of the refrigerating compartment; An outside temperature sensor for sensing the temperature of the outside air; A counter for accumulating the dwell time of the compressor; A refrigerator compartment heater for heating the inside of the refrigerator compartment; When the refrigerating compartment temperature and the outside air temperature are respectively below the compressor operation start temperature and the outside air lower limit temperature, and the continuous pause time and the refrigerating chamber temperature are respectively above a predetermined idle limit time and the compressor operation end temperature, the refrigerator compartment temperature is the compressor operation start.

냉장실온도에 기초하여 압축기의 구동을 제어하는 냉장고에서는, 외기온도의 저하시에는 냉장실의 온도가 상승되지 아니하여 압축기가 장시간 오프상태를 유지하게 되고, 이로 인해, 냉동실의 온도가 일정 이상 상승되는 문제점이 있다. 이러한 문제점은 다음의 두 가지 실시예로부터 해소될 수 있다.
