Abstract (en)
[origin: EP4145074A1] A defrosting control method for a refrigerator includes: measuring a temperature in a storage space, and determining whether the temperature of the storage space reaches a first preset temperature value during a temperature decreasing process; when the temperature of the storage space reaches the first preset temperature value during the temperature decreasing process, starting a defrosting program to perform defrosting once, wherein the defrosting program includes a first defrosting program, and the first defrosting program includes: turning off a low-temperature-level evaporation portion, and starting a first defrosting heating apparatus to heat an evaporator; measuring the temperature in the storage space, and determining whether a difference between the temperature of the storage space and the first preset temperature value is greater than a first preset difference; and when the difference between the temperature of the storage space and the first preset temperature value is greater than the first preset difference, stopping the first defrosting program, and turning on the low-temperature-level evaporation portion. Defrosting can be performed many times in a timely manner, which not only ensures that the refrigeration is not affected by excessive frost, but also avoids the influence of excessive temperature rise caused by the defrosting on the nutritional preservation of food.
