Control method for forward or backward rotary compressor of electric refrigerator

The control method for forward/backward rotation compressor in refrigerator is to sense the overload in the refrigerator and to make the compressor rotate in forward direction to provide great amount of cold air. In order to realize the said function, the present invention makes the compressor rotate in forward or backward direction to maintain the set temperature inside the refrigerator. The operation process includes: the first stage of sensing the close of the refrigerator door and detecting the temperature inside the refrigerator while the door is closed; the second stage of detecting the temperature inside the refrigerator after some set time, judging whether the temperature inside the refrigerator is above the set temperature, and if so, rotating the compressor in forward direction; and the third stage of rotating the compressor in backward direction if the temperature inside the refrigerator is lower than the set temperature. 本发明涉及一种电冰箱的正或逆旋转压缩机的控制方法，进一步说，涉及一种感知电冰箱内的过度的负荷，对应过度的负荷压缩机正方向旋转，快速供给大量冷气的控制方法。为了实现上述功能，本发明提供通过压缩机正或逆旋转来维持电冰箱内的所设定的温度。其运转过程如下：感知冰箱门的关闭，并检查关闭冰箱门时的温度的第一阶段；检查上述电冰箱内的温度后经过所设定时间，再判断检查电冰箱内的温度是否为所设定温度以上，如果电冰箱内的温度为所设定温度以上压缩机正方向旋转的第二阶段；上述判断结果，电冰箱内的温度为所设定温度以下，则压缩机逆方向旋转的第三阶段。
