Problems solved by technology
During the operation of the compressor, the frost layer gradually accumulates. The longer the continuous operation time of the compressor, the thicker the frost layer is, especially as the volume of the refrigerator increases, and consumers store more food in the refrigerator at one time, resulting in long-term operation of the compressor. The set temperature cannot be reached, and a large amount of frost layer accumulates on the surface of the evaporator at this time, which affects the cooling effect of the direct cooling refrigerator and reduces the user experience

The invention discloses a direct cooling refrigerator and a defrosting control method and device thereof. The method comprises the following steps of detecting the temperature of the ambient environment of the direct cooling refrigerator as well as the internal temperature of the cold storage chamber; computing the temperature difference between the ambient temperature and the internal temperature of the cold storage chamber, and determining whether the temperature difference is lower than a preset value; if so, acquiring the maximum continuous operation time of the compressor of the direct cooling refrigerator according to the temperature difference; when the continuous operation time of the compressor reaches the maximum continuous operation time, controlling the compressor to be forcibly powered off so that the direct cooling refrigerator performs defrosting operation. According to the defrosting control method of the direct cooling refrigerator, excessive frosting of an evaporator due to long-time operation of the compressor can be effectively avoided, so that the refrigerating effects of the direct cooling refrigerator can be ensured, and the user experience can be improved.
Description
technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a defrosting control method for a direct cooling refrigerator, a defrosting control device for a direct cooling refrigerator, and a direct cooling refrigerator. Background technique [0002] Traditional direct-cooling refrigerators defrost when the compressor is stopped. Since the temperature in the refrigerator is higher than 0°C, the frost layer will start to melt as soon as the compressor is stopped. During the operation of the compressor, the frost layer gradually accumulates. The longer the continuous operation time of the compressor, the thicker the frost layer is, especially as the volume of the refrigerator increases, and consumers store more food in the refrigerator at one time, resulting in long-term operation of the compressor. The set temperature cannot be reached, and at this time, a large amount of frost layer accumulates on the surface of the evapor...
