Energy-saving control method and energy-saving control device for refrigerator, and refrigerator

Abstract

The invention provides an energy-saving control method and an energy-saving control device for a refrigerator, and the refrigerator. The energy-saving control method for the refrigerator comprises the following steps: detecting and judging an environment temperature interval of an environment temperature of the current environment where the refrigerator is located, and determining a compressor rotational speed gear, a fan rotational speed gear and a defrosting period gear according to a judgement result; and detecting opening-closing action of a door of the refrigerator, and adjusting the compressor rotational speed gear and the fan rotational speed gear or controlling turn-on and turn-off of a fan according to a detection result. According to the technical scheme of the invention, intelligent comprehensive control for the compressor rotational speed gear and the fan rotational speed gear, or control for the turn-on and turn-off of the fan and the defrosting period gear is realized through detecting and judging the environment temperature interval of the environment temperature of the current environment where the refrigerator is located, and detecting the opening-closing action of the door, thus the refrigerator achieves intelligent energy saving, the storage quality of foods in the refrigerator is ensured, the noise of the refrigerator is lowered, energy loss is reduced, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of energy-saving control, in particular to an energy-saving control method for a refrigerator, an energy-saving control device for a refrigerator, and a refrigerator. Background technique [0002] The control of refrigerators in related technologies generally has the following defects: first, the speed control of the compressor and the fan of the refrigerator is only controlled according to the ambient temperature, without comprehensive control combined with the change of the door opening of the refrigerator, which wastes energy consumption; secondly, the control of the refrigerator during the daytime It is consistent with the night control, and does not consider that the refrigerator can be more energy-efficient at night; thirdly, the defrosting time of the refrigerator is determined according to the ambient temperature, and does not consider the impact of opening the door on defrosting, which will a...
