Problems solved by technology
Although the air-cooled refrigerator has the advantages of fast refrigeration speed and uniform temperature control, it will also cause the problem of frosting on the evaporator. Because the temperature of the evaporator is low, the water vapor in the air will form frost on the surface of the evaporator, which will affect the refrigerator. cooling effect
[0003] At present, air-cooled refrigerators mainly start the defrosting process according to the running time of the compressor. However, this defrosting method has low accuracy and poor effect

Embodiment Construction
[0026] figure 1 is a schematic diagram of an air-cooled refrigerator 10 according to an embodiment of the present invention, figure 2 is a side sectional view of the bottom of an air-cooled refrigerator 10 according to an embodiment of the present invention, and in figure 1 In the air-cooled refrigerator 10 shown, in order to illustrate an embodiment of the present invention, components such as the door body of the air-cooled refrigerator 10 are not shown.
[0027] This embodiment provides an air-cooled refrigerator 10 in which the evaporator chamber 121 is located at the inner lower part of the freezer inner container. The air-cooled refrigerator 10 generally includes a box body 100, and the box body 100 includes an outer shell and storage placed inside the outer shell. A storage space 110 is defined in the storage liner. The storage liner generally includes a refrigerated liner, a refrigerated liner, etc. The refrigerated liner is located below the refrigerated liner. The ...

The invention provides an air cooling refrigerator and a defrosting control method thereof. Firstly, whether the wind volume changing speed of airflow flowing through an evaporator of the air coolingrefrigerator is larger than the preset wind volume changing speed threshold value or not is judged, if the wind volume changing speed of airflow flowing through the evaporator of the air cooling refrigerator is larger than the preset wind volume changing speed threshold value, whether a compressor of the air cooling refrigerator meets the defrosting condition or not is judged, and if the defrosting condition is met, the defrosting process of the air cooling refrigerator is triggered. When the compressor meets the defrosting condition, it is not indicated that the evaporator needs to be defrosted, if evaporator defrosting can influence the refrigeration effect of the air cooling refrigerator at the time and the defrosting degree of the evaporator surface is different, the wind volume changing speed of airflow flowing through the evaporator of the air cooling refrigerator can change, and therefore whether the evaporator needs to be defrosted or not is jointly judged according to the windvolume changing speed and the compressor defrosting condition, and air cooling refrigerator defrosting control accuracy can be improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-cooled refrigerator and a defrosting control method thereof. Background technique [0002] The air-cooled refrigerator cools the air flowing through the evaporator room through the evaporator in the evaporator room, and then drives the air flow through the fan to realize cooling. Although the air-cooled refrigerator has the advantages of fast refrigeration speed and uniform temperature control, it will also cause the problem of frosting on the evaporator. Because the temperature of the evaporator is low, the water vapor in the air will form frost on the surface of the evaporator, which will affect the refrigerator. cooling effect. [0003] At present, air-cooled refrigerators mainly start the defrosting process according to the running time of the compressor. However, this defrosting method has low accuracy and poor effect.
