Air conditioner snow accumulation prevention control method and device, air conditioner and storage medium

Abstract

The invention provides an air conditioner snow accumulation prevention control method and device, an air conditioner and a storage medium and relates to the technical field of air conditioners. The air conditioner snow accumulation prevention control method comprises the steps of obtaining operation parameters of the air conditioner and judging whether the operation parameters satisfy a preset snow removing condition or not; if the preset snow removing condition is satisfied, after controlling an outdoor fan of the air conditioner to operate for a first preset time at a first rotation speed, detecting a first operation current of the outdoor fan; and controlling starting to clear accumulated snow of the outdoor fan according to the first operation current and a pre-obtained sunny day detection current. According to the air conditioner snow accumulation prevention control method and device, the air conditioner and the storage medium, by combining the operation parameters, the entering of accumulated snow clearing operation can be accurately recognized; the load state of the outdoor fan can be effectively judged according to the first operation current and the sunny day detection current; and therefore, the accumulated snow clearing operation is accurately controlled by accurately recognizing the snow accumulation situation, the intelligence, timeliness and high efficiency of airconditioner snow removal are guaranteed, and the situation that air conditioner accumulated snow is stacked is prevented so that the air conditioner can also normally operate in a severe and cold weather to facilitate the use of users.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method and device for preventing snow accumulation of an air conditioner, an air conditioner and a storage medium. Background technique [0002] In severe cold weather, the air conditioner is prone to a large amount of snow accumulation on the outdoor fan, which hinders the normal start of the air conditioner and even damages the outdoor fan of the air conditioner. Aiming at the problem of anti-snow accumulation of air conditioners, existing air conditioner manufacturers adopt the method of dialing code setting to realize the anti-snow function. In this method, when it is snowing outside, the switch of the anti-snow function needs to be manually dialed. When the anti-snow function is turned on, the fan is turned on to a fixed speed, and then turned off after a fixed period of time, waiting for the next cycle to start again. snow removal.
