Control method of air cooling refrigerator and air cooling refrigerator

Abstract

The invention provides a control method of an air cooling refrigerator. The method comprises the steps as follows: in a refrigeration process of the air cooling refrigerator, whether the air cooling refrigerator meets a defrosting condition is judged; if the air cooling refrigerator meets the defrosting condition, a compressor of the air cooling refrigerator is controlled to be shut down, and a refrigerating blower is continuously controlled to operate a first preset time and then be closed; and after the refrigerating blower closes a second preset time, the air cooling refrigerator is controlled to enter a defrosting mode for defrosting. According to the control method of the air cooling refrigerator, the defrosting efficiency is improved, the energy consumption is reduced, and food deterioration caused by larger fluctuations of temperatures in refrigerator compartments can be avoided. The invention further provides the air cooling refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a control method of an air-cooled refrigerator and the air-cooled refrigerator. Background technique [0002] At present, during the defrosting process of existing air-cooled refrigerators (such as defrosting the evaporator in the freezing chamber), the temperature of the frozen items in the box will rise by about 3°C. The temperature inside the freezer rises a lot during the defrosting process, and the compressor needs to run continuously for a long time to reduce the temperature inside the freezer to -18°C, which wastes electricity and risks food spoilage. [0003] In the existing methods, in order to solve the above-mentioned temperature, the usual practice is to reduce the temperature rise of the freezer during the defrosting process. Some refrigerators have added a pre-cooling function, that is, the refrigeration system of the air-cooled refrigerator is contr...

Problems solved by technology

[0002] At present, during the defrosting process of existing air-cooled refrigerators (such as defrosting the evaporator in the freezing chamber), the temperature of the frozen items in the box will rise by about 3°C. The temperature inside the freezer rises a lot during the defrosting process, and the compressor needs to run continuously for a long time to reduce the temperature inside the freezer to -18°C, which wastes electricity and risks food spoilage

[0003] In the existing methods, in order to solve the above-mentioned temperature, the usual practice is to reduce the temperature rise of the freezer during the defrosting process. Some refrigerators have added a pre-cooling function, that is, the refrigeration system of the air-cooled refrigerator is controlled to run continuously for a period of time before defrosting. Lower the food temperature to a lower temperature and then defrost. This solution can ensure that the food will not melt and deteriorate during the defrosting process (that is, the temperature in the compartment of the air-cooled refrigerator will not rise to a higher temperature during the defrosting process. ), but the continuous operation of the compressor will consume more energy, and the energy consumption is high
