Refrigerator defrosting control method

Abstract

The invention provides a refrigerator defrosting control method. The refrigerator defrosting control method comprises the steps that the temperature in a storage space is detected, and whether the temperature of the storage space reaches a first preset temperature value or not in the decreasing process is judged; when the temperature of the storage space reaches a first preset temperature value in the decreasing process, a defrosting program is started to conduct primary defrosting; the defrosting program comprises a first defrosting program; the first defrosting program comprises the steps that a low-temperature-stage evaporation part is closed, and a first defrosting heating device is started to heat an evaporator; the temperature in the storage space is detected, and whether a difference value between the temperature of the storage space and a first preset temperature value is larger than a first preset difference value or not is judged; and when the difference value between the temperature of the storage space and the first preset temperature value is larger than the first preset difference value, the first defrosting program is closed, and the low-temperature-stage evaporation part is started. Defrosting can be carried out for multiple times in time, it is guaranteed that refrigeration is not affected by too much frosting, and meanwhile the situation that temperature rise caused by defrosting is too large, and food nutrition preservation is affected is avoided.

Description

technical field [0001] The invention relates to the field of refrigerated storage, in particular to a defrosting control method for a refrigerator. Background technique [0002] At present, the temperature range of the variable temperature compartment of refrigerators on the market is mostly adjusted between 8-18°C, and the overall design is more conventional. With the gradual improvement of people's living standards, this type of temperature zone refrigerator can no longer meet everyone's needs well. It is necessary to design a high-end refrigerator with a wider temperature range and more complete functions that can meet more needs of users. Preservation in a glassy state below -40°C is conducive to the maximum preservation of food nutritional value. There is a demand for ultra-low temperature chambers (-40~-60°C) in the high-end user market. In order to improve user satisfaction, we must pay close attention to user experience. For this reason, conventional cascade compres...
