Abstract
본 발명은 냉장고의 팬모터 제어장치에 관한 것으로, 냉장고 고내의 공기를 변화시키는 증발기(2)에 서리가 착상되면 통풍저항이 증가하여 팬모터(4)에 걸리는 토오크가 증가하여 팬모터(4)의 회전수 감소에 의해 팬(3)에 의한 풍량이 감소되므로서 증발기(2)의 열교환량이 감소되어 소비전력이 증가하고, 또한 증발기(2)에 착상된 서리의 량에 관계없이 제상시기가 일정하게 결정되어 제상효율이 떨어지는 문제점을 해결하기 위한 것이다.The present invention relates to a fan motor control apparatus of a refrigerator. When frost is formed on an evaporator 2 that changes air in a refrigerator, ventilation resistance is increased so that the torque applied to the fan motor 4 increases, thereby increasing the fan motor 4. As the amount of air flow by the fan 3 decreases due to the decrease in the number of revolutions, the heat exchange amount of the evaporator 2 decreases, the power consumption increases, and the defrosting timing is constant regardless of the amount of frost formed on the evaporator 2. It is determined to solve the problem of low defrosting efficiency.
본 발명은 이와같은 종래 문제점을 해결하기 위하여 팬모터의 회전수를 감지하는 센서부와 감지된 회전수를 비교하는 제어부 및 팬모터의 회전수를 조절하는 인버터를 구비하여 서리가 착상된 증발기의 통풍저항에 의해 팬모터에 걸리는 토오크의 증가로 인해 팬모터의 회전수가 감소되는 것을 비교하여 일정한 회전수를 유지시키고 팬모터에 걸리는 부하를 측정하여 초기에 설정된 초대부하를 초과하였을때 제상 히터를 구동시켜 증발기에 착상된 서리를 제상시키도록 하므로서 증발기의 제상효율 및 열교환 성능을 향상시켜 소비전력을 절감시키도록 한 것으로 냉장고에 적용한다.The present invention has a sensor unit for detecting the rotational speed of the fan motor, a control unit for comparing the detected rotational speed and an inverter for adjusting the rotational speed of the fan motor in order to solve such a conventional problem ventilation of the evaporator frost is implanted Compared to the decrease in the rotational speed of the fan motor due to the increase in the torque applied to the fan motor by the resistance, it maintains a constant rotational speed and measures the load on the fan motor to drive the defrost heater when the initial load is exceeded. By defrosting the frost on the evaporator to improve the defrosting efficiency and heat exchange performance of the evaporator to reduce the power consumption applied to the refrigerator.
