이하, 도 1과 도 2를 참조하여, 종래기술에 따른 냉장고의 운전 제어방법을 설명하면 다음과 같다.1 and 2, the operation control method of the refrigerator according to the prior art will be described.

첫째, 제1 냉장실(3)과 제2 냉장실(4)의 온도 중 제1 냉장실의 온도가 설정온도범위(A)의 상한치(b)를 초과할 경우, RF 사이클 운전을 시작하는 단계와, 이와 동시에 냉장실용 증발기팬(14a)을 구동시키는 단계와, 이와 동시에 제1 냉장실용 댐퍼(7)를 개방시키는 단계와, 소정시간이 지나 상기 제1 냉장실의 온도가 설정온도범위(A)의 하한치(a)에 도달할 경우 상기 제1 냉장실용 댐퍼(7)를 차단시키는 단계로 이루어진다.First, when the temperature of the first refrigerator compartment among the temperatures of the first refrigerator compartment (3) and the second refrigerator compartment 4 exceeds the upper limit (b) of the set temperature range (A), starting the RF cycle operation, and Simultaneously driving the refrigerator compartment evaporator fan 14a; simultaneously opening the first refrigerator compartment damper 7; and after a predetermined time, the temperature of the first refrigerator compartment is equal to the lower limit of the set temperature range (A). When the a) is reached, the first refrigeration chamber damper 7 is blocked.

둘째, 제1 냉장실(3)과 제2 냉장실(4)의 온도 중 제2 냉장실의 온도가 설정온도범위(B)의 상한치(d)를 초과할 결우, RF 사이클 운전을 시작하는 단계와, 이와 동시에 냉장실용 증발기팬(14a)을 구동시키는 단계와, 이와 동시에 제2 냉장실용 댐퍼(8)를 개방시키는 단계와, 소정시간이 지나 상기 제2 냉장실의 온도가 설정온도범위(B)의 하한치(c)에 도달할 경우 상기 제2 냉장실용 댐퍼(8)를 차단시키는 단계로 이루어진다.Secondly, if the temperature of the second refrigerating compartment among the temperatures of the first refrigerating compartment (3) and the second refrigerating compartment (4) exceeds the upper limit (d) of the set temperature range (B), starting the RF cycle operation, and Simultaneously driving the refrigerator compartment evaporator fan 14a; simultaneously opening the second refrigerator compartment damper 8; and after a predetermined time, the temperature of the second refrigerator compartment is equal to the lower limit of the set temperature range (B). c) blocking the second refrigerating chamber damper (8).

셋째, 제1 냉장실(3)과 제2 냉장실(4)의 온도가 각 설정온도범위(A,B)내에 도달하면, RF 사이클을 종료하는 단계로 이루어진다.Third, when the temperatures of the first refrigerating chamber 3 and the second refrigerating chamber 4 reach within the set temperature ranges A and B, the RF cycle is terminated.

하지만, 상기와 같이 이루어진 종래기술에 따른 냉장고의 운전 제어방법은다음과 같은 문제점을 가지고 있다.However, the operation control method of the refrigerator according to the prior art made as described above has the following problems.

도 2에 도시된 바와 같이, 제1 냉장실(3)과 제2 냉장실(4)의 온도가 각 설정온도범위(A,B)내에 있도록 하기 위해, RF 사이클 및 냉장실용 증발기팬(14a)은 제1 냉장실의 온도가 설정온도범위(A)의 상한치(b)에 도달할 때 뿐만 아니라 제2 냉장실의 온도가 설정온도범위(B)의 상한치(d)에 도달할 때에도 운전 및 구동하게 되는데, 이 때, 상기와 같이, RF 사이클 및 하나의 냉장실용 증발기팬(14a)이 제1 냉장실(3) 및 제2 냉장실(4)의 온도에 따라 독립적으로 운전 및 구동하게 되면, RF 사이클이 짧은 시간 간격으로 온/오프를 반복하게 되고, 또한 냉장실용 증발기팬(14a)의 초기 구동횟수는 증가하게 된다(도 2의 Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ 참조).As shown in FIG. 2, in order to ensure that the temperatures of the first refrigerating compartment 3 and the second refrigerating compartment 4 are within the respective set temperature ranges A and B, the RF cycle and the refrigerating compartment evaporator fan 14a are provided. It operates and operates not only when the temperature of the first refrigerator compartment reaches the upper limit value (b) of the set temperature range (A) but also when the temperature of the second refrigerator compartment reaches the upper limit value (d) of the set temperature range (B). As described above, when the RF cycle and one refrigerator compartment evaporator fan 14a are operated and driven independently according to the temperatures of the first refrigerator compartment 3 and the second refrigerator compartment 4, the RF cycles are shortly timed. The on / off is repeated, and the initial driving frequency of the refrigerating chamber evaporator fan 14a is increased (see I, II, III, IV, and V in FIG. 2).

결국, 기기(냉장고)의 수명이 단축되고, 기기의 운전소음이 증가되며, RF 사이클의 초기 구동 횟수가 잦아짐에 따라 소비전력이 증가되었다.As a result, the lifespan of the device (refrigerator) is shortened, the operation noise of the device is increased, and the power consumption increases as the number of initial driving cycles of the RF cycle increases.

본 발명은 종래기술에 대한 문제점을 해결하기 위한 것으로서, 냉장고의 운전제어방법을 개선하여, 기기의 수명을 연장시킴과 함께, 기기의 운전소음 및 소비전력을 저감시키는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and has an object of improving the operation control method of the refrigerator, extending the life of the device, and reducing the operation noise and power consumption of the device.

When the temperature of the refrigerating chamber 4 reaches the lower limit c of the set temperature range B, the second refrigerating chamber damper 8 is closed.

셋째, 제1 냉장실(3)과 제2 냉장실(4)의 온도가 각 설정온도범위(A,B)내에 도달하면, RF 사이클을 종료하는 단계로 이루어진다.Third, when the temperatures of the first refrigerating chamber 3 and the second refrigerating chamber 4 reach within the set temperature ranges A and B, the RF cycle is terminated.

결국, 본 발명은, 상기한 동시냉각패턴이 이루어지도록 냉장고의 운전제어방법을 개선함에 따라, RF 사이클 운전 및 냉장실용 증발기팬(14a)의 온/오프 반복횟수를 줄일 수 있어, 기기의 수명을 연장시킬 수 있음과 함께 기기의 운전소음 및 소비전력을 저감시킬 수 있게 된다.As a result, the present invention improves the operation control method of the refrigerator to achieve the above-described simultaneous cooling pattern, thereby reducing the number of on / off repetition times of the RF cycle operation and the evaporator fan 14a for the refrigerating chamber, thereby reducing the life of the device. In addition, the operation noise and power consumption of the device can be reduced.
