본 발명은 정/역회전 운전이 가능한 압축기를 채용한 냉장고에 관한 것으로, 특히 냉장고의 온도변화에 따라 압축기의 현재 회전 방향 변경이 필요한 경우에, 압축기를 소정 시간동안 오프시킨 다음에 회전 방향을 변경하여 압축기를 운전시키도록 한 냉장고의 정/역회전 압축기 제어방법에 관한 것이다.The present invention relates to a refrigerator employing a compressor capable of forward / reverse rotation operation. In particular, when the current rotation direction of the compressor needs to be changed according to the temperature change of the refrigerator, the compressor is turned off for a predetermined time and then the rotation direction is changed. The present invention relates to a forward / reverse compressor control method for a refrigerator for operating a compressor.

일반적으로, 냉장고에 적용되는 냉동 싸이클의 경우, 냉동실의 냉기 공급을 위한 고냉력 싸이클과 냉장실의 냉기 공급을 위한 저냉력 싸이클로 구분된다.In general, in the case of a refrigeration cycle applied to the refrigerator, it is divided into a high cold cycle for supplying cold air in the freezer compartment and a low cold cycle for supplying cold air in the refrigerating compartment.

이때, 상기 고냉력 냉동 싸이클이나 저냉력 냉동싸이클은, 팽창수단의 길이가 동일하여 운전모드에 따른 최적의 냉동싸이클을 구현하지 못하는데, 이와같은 종래 기술을 첨부한 도면을 참조하여 설명한다.In this case, the high-cooling refrigeration cycle or low-cold-freezing cycle, the length of the expansion means does not implement the optimal refrigeration cycle according to the operation mode, will be described with reference to the accompanying drawings.

도1은 일반적인 냉장고의 냉동싸이클을 보인 보인 개략도로서, 이에 도시된 바와같이 증발기에서 토출되는 저온, 저압의 냉매증기를 흡입하여 이를 압축함으로써 고온, 고압의 증기로 만드는 압축기(1)와; 상기 압축기(1)에서 토출된 고온, 고압의 냉매증기의 열을 물 또는 공기 중에 방출시키고, 고압의 포화액으로 변화시키는 응축기(2)와; 상기 응축기(2)에서 토출된 고압의 포화액을, 모세관(3)을 통해 통해 저온, 저압의 냉매로 흡입하여 이를 증발시켜, 냉동실로 열교환하여 차가워진 공기를 배출하는 제1 증발기(F-EVA)와; 상기 응축기(2)에서 토출된 고압의 포화액을, 모세관(3)을 통해 저온,저압의 냉매로 흡입하여 이를 증발시켜, 냉장실로 열교 환하여 차가워진 공기를 배출하는 제2 증발기(R-EVA)를 구비하며, 이와같은 냉동싸이클을 설명한다.1 is a schematic view showing a refrigerating cycle of a typical refrigerator, as shown in FIG. 1, a compressor (1) which makes high-temperature, high-pressure steam by sucking and compressing a low-temperature, low-pressure refrigerant vapor discharged from an evaporator; A condenser (2) for dissipating the heat of the high-temperature, high-pressure refrigerant vapor discharged from the compressor (1) into water or air, and changing it into a high-pressure saturated liquid; The first evaporator (F-EVA) which sucks the high pressure saturated liquid discharged from the condenser 2 into the refrigerant of low temperature and low pressure through the capillary tube 3, evaporates it, and heats it into a freezing chamber to discharge cold air. )Wow; A second evaporator (R-EVA) for sucking the high pressure saturated liquid discharged from the condenser 2 into the refrigerant having a low temperature and low pressure through the capillary tube 3 and evaporating it, and exchanging heat to the refrigerating chamber to discharge cold air. And a refrigeration cycle.

먼저, 냉동 운전시(고냉력 운전시), 압축기(1)에서 압축된 고온고압의 냉매는, 응축기(2)로 유입되어 응축된후, 모세관(3)을 지나면서 저온저압의 냉매로 된다.First, in the freezing operation (high cooling operation), the high temperature and high pressure refrigerant compressed by the compressor 1 flows into the condenser 2, condenses, and passes through the capillary tube 3 to become a low temperature low pressure refrigerant.

이후, 제1 증발기(F-EVA)는 상기 저온저압 냉매를 흡입하여 이를 증발시켜, 냉동실로 액분이 없는 포화증기를 배출한다. Thereafter, the first evaporator (F-EVA) sucks the low-temperature low-pressure refrigerant and evaporates it, and discharges saturated steam without liquid to the freezer compartment.

냉장 운전시(저냉력 운전시), 압축기(1)에서 압축된 고온고압의 냉매는, 응축기(2)로 유입되어 응축된후, 모세관(3)을 지나면서 저온저압의 냉매로 된다.In the cold storage operation (low cooling power operation), the high temperature and high pressure refrigerant compressed by the compressor 1 flows into the condenser 2, condenses, and passes through the capillary tube 3 to become a low temperature low pressure refrigerant.

이후, 제2 증발기(R-EVA)는 상기 저온저압 냉매를 흡입하여 이를 증발시켜, 냉동실로 열교환하여 차가워진 공기를 배출한다.Thereafter, the second evaporator (R-EVA) inhales and evaporates the low temperature and low pressure refrigerant, and heats it into a freezer compartment to discharge cold air.

여기서, 상술한 냉장고의 냉동 싸이클에 채용되는 압축기는 정방향으로만 회전하여 항상 고출력을 발생하게 되고, 이에 따라 냉장고내의 온도가 안정된 상태를 유지하여 큰 냉력이 필요하지 않은 경우에도, 압축기를 정회전으로 회전시키므로 전력 소모가 증가되는 문제점이 있다.Here, the compressor employed in the above-mentioned refrigeration cycle of the refrigerator rotates only in the forward direction and always generates a high output. Accordingly, even when the temperature in the refrigerator is kept stable and a large cooling force is not required, the compressor is rotated forward. There is a problem that the power consumption is increased because it rotates.

이를 해결하기 위하여, 냉장고에, 냉력에 따라 정방향 또는 역방향으로 회전시키는 압축기를 채용하여, 냉력을 발생함으로써, 전력 소모를 감소시키는 기술이 사용되고 있는데, 즉 냉장고가 일정 운전시점이 지나서, 안정된 상태로 인식되면, 작은 냉력을 발생하는 역방향으로 압축기를 구동함으로써, 전력소모를 감소시킨다.In order to solve this problem, the refrigerator employs a compressor that rotates in a forward or reverse direction according to the cooling power, and generates a cooling force, thereby reducing power consumption. That is, the refrigerator is recognized as a stable state after a certain operating point. This reduces power consumption by driving the compressor in the reverse direction to generate a small cooling force.

상술한 종래기술에 있어서, 현재 정방향 또는 역방향으로 운전하는 압축기 를, 냉장고의 온도변화에 의해 회전 방향을 변경하는 경우에, 압력차가 발생하여 압축기가 손상되는 문제점이 있다. In the above-described prior art, there is a problem that a pressure difference occurs and the compressor is damaged when the direction of rotation of the compressor currently operating in the forward or reverse direction is changed by the temperature change of the refrigerator.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 냉장고의 온도변화에 따라 압축기의 현재 회전 방향 변경이 필요한 경우에, 압축기를 소정 시간동안 오프시킨 다음에 회전 방향을 변경하여 압축기를 운전시킴으로써, 압축기의 손상을 미연에 방지하도록 한 냉장고의 정/역회전 압축기 운전제어방법을 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, and when the current rotation direction of the compressor is required to change according to the temperature change of the refrigerator, by turning off the compressor for a predetermined time and then operating the compressor by changing the rotation direction Another object of the present invention is to provide a forward / reverse compressor operation control method of a refrigerator to prevent damage to a compressor.

As shown in FIG. 2, a user operates a compressor of a refrigerator while the current direction of the compressor is forward rotation or reverse rotation.

SP 17), the operation of the present invention will be described.

먼저, 사용자에 의해, 냉장고의 압축기를 운전시키면서, 현재 압축기의 운전방향이 정회전인지 또는 역회전인지를 판단한다(SP1~SP3), First, while the compressor of the refrigerator is operated by the user, it is determined whether the driving direction of the current compressor is forward rotation or reverse rotation (SP1 to SP3).

SP5, SP6)

상기 판단결과(SP6), 압축기를 정회전시키도록 선택되면, 압축기를 계속하여 정회전 운전시키고(SP7), 만약 압축기를 역회전시키도록 선택되면, 압축기를 오프시킨 다음(SP8), 소정 시간(대략 7분)이 경과하면 압축기를 역회전 운전시킨다 (SP9,SP10).As a result of the determination (SP6), if the compressor is selected to rotate forward, the compressor continues to run forward (SP7). If the compressor is selected to reverse rotation, the compressor is turned off (SP8), and then the predetermined time ( After approximately 7 minutes), the compressor runs in reverse rotation (SP9, SP10).

한편, 상기 판단결과(SP3), 현재 압축기의 운전방향이 역회전이면,냉장고내의 온도를 감지하고(SP11), 그 고내 온도가 설정온도 보다 낮아서 현재 압축기의 운전이 역회전으로 선택되는지를 판단한다(SP12,SP13).On the other hand, the determination result (SP3), if the current direction of operation of the compressor is reverse rotation, the temperature in the refrigerator is detected (SP11), and the temperature in the refrigerator is lower than the set temperature to determine whether the operation of the current compressor is selected as reverse rotation.

If the compressor is selected to rotate forward, the compressor is turned off (SP15) and then the predetermined time ( After approximately 7 minutes), the compressor runs forward (SP16, SP17).

이상에서 상세히 설명한 바와같이 본 발명은, 정회전 또는 역회전으로 운전하는 압축기의 운전방향을 감지한후, 냉장고의 온도변화에 따른 회전 방향 변경이 필요한 경우에, 압축기를 소정 시간동안 오프시킨 다음에 회전 방향을 변경하여 압축기를 운전시킴으로써, 압축기의 신뢰성을 확보하는 효과가 있다.As described in detail above, the present invention, after detecting the direction of operation of the compressor running in the forward or reverse rotation, when the rotational direction is required to change according to the temperature change of the refrigerator, after turning off the compressor for a predetermined time By operating the compressor by changing the rotation direction, there is an effect of ensuring the reliability of the compressor.
