The invention discloses a
defrosting control method and device for a refrigerator. The method includes the following steps that the accumulative
operating time of a compressor and the opening frequency of a refrigerator door are recorded, every time the door is opened, the environment temperature and the environment
humidity are detected, and the door opening
hold time is recorded; whether a
defrosting starting condition is met or not is judged according to the accumulative
operating time of the compressor and the opening frequency of the refrigerator door; if the
defrosting starting condition is met, after defrosting is started, the defrosting exit temperature is acquired according to the environment temperature, the environment
humidity and the door opening
hold time detected every time the door is opened; when the temperature of an
evaporator of the refrigerator reaches the defrosting exit temperature, the refrigerator is controlled to complete defrosting, hence, the defrosting time can be controlled according to the actual environment temperature and
humidity, the purpose of thorough defrosting when a large amount of
frost exists and the purpose of
power consumption reducing when a small amount of
frost exists are achieved, defrosting is more accurate, and better
electricity saving and fresh-keeping effects can be brought to users.
