Embodiment Construction
[0017] Air-cooled refrigerator natural defrosting method of the present invention is carried out according to the following steps:
[0018] The first step is that after the accumulative running time of the compressor reaches TDFTACC hours, the electric control device of the refrigerator controls the refrigerator to enter the second step, which is the defrosting preparation step;
[0019] Among them, TDFTACC is the accumulative running time of one cycle of the compressor preset before the refrigerator leaves the factory (the user cannot adjust it), and its value range is 4.5≤TDFTACC≤15 hours;
[0020] The second step is the defrosting preparation step;
[0021] If the refrigerating damper is open at this time, the damper will continue to open until the refrigerating room temperature difference is lower than the cooling direction and reaches the THROFF zone; the THROFF zone is the preset refrigerating damper closing temperature zone before the refrigerator leaves the factory, an...
