Problems solved by technology

However, the existing technology can only defrost and dewater the outdoor heat exchanger without taking into account the accumulation of water in the chassis, and the problem of accumulated icing still occurs, resulting in low applicability of the defrosting method

Abstract

The invention relates to the technical field of intelligent household appliances, and discloses an air conditioner defrosting method which comprises the steps that under the condition of defrosting operation, the target fan rotating speed is determined according to the cleanliness degree of an air conditioner; the electric heating device is started, and the outdoor fan is controlled to rotate in the reverse direction at the target fan rotating speed, so that a high-temperature air zone is formed between the outdoor fan and the outdoor heat exchanger; wherein the cleaning degree is associated with the frosting degree of the outdoor heat exchanger and the water accumulation degree of the air conditioner. By means of the formed high-temperature wind belt, defrosting can be rapidly conducted, residual condensate water on the outdoor heat exchanger side and the chassis side can be removed while rapid defrosting is conducted, the situation of accumulated icing is avoided, and the applicability of the defrosting method is improved. The invention further discloses a defrosting device for the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for defrosting an air conditioner, and an air conditioner. Background technique [0002] At present, when the air conditioner is heating, if the outdoor ambient temperature is too low, the outdoor machine of the air conditioner will frost, and the frost on the outdoor heat exchanger will cause the heat exchange efficiency to be too low, which will eventually lead to a decrease in the air outlet temperature of the air conditioner. , the user experience becomes worse. At this time, the air conditioner will generally enter the defrost, so as to avoid the situation that the heat exchange effect is deteriorated. However, the defrosting of the air conditioner often encounters the problem that the defrosting of the outdoor heat exchanger is not clean, which leads to the reduction of the heat exchange efficiency of the outdoor heat exchanger an...
