이하, 첨부된 도면을 참조하여 본 발명에 따른 김치냉장고의 냉기순환장치의 작용 및 효과를 설명한다.Hereinafter, with reference to the accompanying drawings will be described the operation and effect of the cold air circulation device of the kimchi refrigerator according to the present invention.

도 5 및 도 6은 본 발명에 따른 김치냉장고의 냉기순환장치의 작동예를 도시한 설명도로서, 도 4 및 도 5를 참조하면, 제어부는 상기 우측 저장실(120)의 온도센서를 통해 검출된 온도가 우측 저장실(120)의 기 설정된 온도보다 높고, 좌측 저장실(110)의 온도센서를 통해 검출된 온도가 우측 저장실(120)의 온도센서를 통해 검출된 온도보다 낮은 경우, 제 1댐퍼(141) 및 제 2댐퍼(151)가 개방되도록 제어신호를 출력하여 상기 제 1연통홀(140) 및 제 2연통홀(150)이 개방되도록 한다.5 and 6 are explanatory diagrams showing an example of the operation of the cold air circulation apparatus of the kimchi refrigerator according to the present invention. Referring to FIGS. 4 and 5, the controller is detected by the temperature sensor of the right storage chamber 120. When the temperature is higher than the preset temperature of the right storage compartment 120 and the temperature detected by the temperature sensor of the left storage compartment 110 is lower than the temperature detected by the temperature sensor of the right storage compartment 120, the first damper 141. And the control signal is output to open the second damper 151 so that the first communication hole 140 and the second communication hole 150 are opened.

이와 동시에 상기 제 2송풍팬(143) 및 제 4송풍팬(153)이 작동하여 좌측 저장실(110)의 냉기가 제 1연통홀(140)을 통해 우측 저장실(120)로 유입되고, 우측 저장실(120)의 냉기는 제 2연통홀(150)을 통해 좌측 저장실(110)로 유입되면서, 좌측 저장실(110) 및 우측 저장실(120)의 냉기가 서로 순환되도록 한다.At the same time, the second blower fan 143 and the fourth blower fan 153 operate to allow cold air from the left storage compartment 110 to flow into the right storage compartment 120 through the first communication hole 140 and to store the right storage compartment ( The cold air of the 120 is introduced into the left storage compartment 110 through the second communication hole 150, thereby allowing the cold air of the left storage compartment 110 and the right storage compartment 120 to circulate with each other.

Since the cold air temperature of the portion adjacent to 130 is the lowest, the cold air flows directly into the right storage compartment 120, thereby effectively lowering the temperature of the right storage compartment 120.

이때, 좌측 저장실 도어(111) 및 우측 저장실 도어(121)에 장착된 냉각팬(112, 122; 도 3참조)도 함께 작동하여 상기 순환되는 냉기가 종방향으로도 순환되도록 함으로써, 더욱 효과적으로 저장실 내부의 냉기가 순환되도록 한다. 또한, 우측 저장실(120) 내부의 온도가 설정온도까지 하강되면, 상기 제 1댐퍼(141) 및 제 2댐퍼(151)가 폐쇄되도록 하고, 제 2송풍팬(143) 및 제 4송풍팬(153)의 작동이 정지되도록 하여 좌측 저장실(110) 및 우측 저장실(120)이 서로 독립적으로 냉각되도록 한다.At this time, the cooling fans 112 and 122 (refer to FIG. 3) mounted to the left storage compartment door 111 and the right storage compartment door 121 are also operated to allow the circulating cold air to be circulated in the longitudinal direction, thereby more effectively inside the storage compartment. Let cool air circulate. In addition, when the temperature inside the right storage compartment 120 drops to a predetermined temperature, the first damper 141 and the second damper 151 are closed, and the second blowing fan 143 and the fourth blowing fan 153 are closed. ) Is stopped to allow the left storage compartment 110 and the right storage compartment 120 to be cooled independently of each other.

한편, 도 4 및 도 6을 참조하면, 제어부는 상기 우측 저장실(120)의 온도센서를 통해 검출된 온도가 우측 저장실(120)의 기 설정된 온도보다 높고, 우측 저장실(120)의 온도센서를 통해 검출된 온도가 좌측 저장실(110)의 온도센서를 통해 검출된 온도보다 낮은 경우, 제 1댐퍼(141) 및 제 2댐퍼(151)가 개방되도록 제어신호를 출력하여 상기 제 1연통홀(140) 및 제 2연통홀(150)이 개방되도록 한다.4 and 6, the controller detects that the temperature detected by the temperature sensor of the right storage compartment 120 is higher than the preset temperature of the right storage compartment 120 and through the temperature sensor of the right storage compartment 120.
