Refrigerator and control method thereof

Abstract

The invention provides a refrigerator and a control method thereof. The control method comprises the following steps: determining whether the refrigerator is overloaded or not; if the refrigerator is overloaded, when the accumulative refrigerating time of the refrigerator in overloaded state is larger than a first preset time, stopping refrigeration and performing defrosting, wherein the first preset time is smaller than a preset defrosting interval time of the refrigerator; and if the refrigerator is not overloaded, adjusting the defrosting interval time of the refrigerator according to door opening times of the refrigerator. The control method provided by the embodiment of the invention has the advantage that while the energy consumption of defrosting is reduced, sufficient defrosting is ensured, and thus the performance of the refrigerator is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a refrigerator and a control method thereof. Background technique [0002] With the improvement of the quality of life and the acceleration of the pace of life, consumers are buying more and more food, so the demand for refrigerators has also greatly increased. Refrigerators include mechanical temperature-controlled refrigerators and computer-controlled temperature-controlled refrigerators (electrically controlled refrigerators). Among them, electronically controlled refrigerators have functions such as quick cooling, quick freezing, and defrosting. [0003] The defrosting methods of existing refrigerators that defrost through heaters usually adopt the following defrosting methods: enter defrosting through timing; exit defrosting when the temperature of the detection sensor is reached; When the temperature is reached, exit defrosting. [0004] However, the exist...

AI Technical Summary

Problems solved by technology

[0005] 1. When the load of the refrigerator is heavy, the defrosting is not complete;

[0006] 2. When the load of the refrigerator is small, the excess energy consumption
