The invention provides an air conditioner, and an accumulated dust detection method and an accumulated dust detection device thereof. The accumulated dust detection method includes: judging if an indoor machine reaches stable work conditions; if yes, judging if power of a wind wheel draught fan of the indoor machine under a current work wind grade is less than set power threshold value of the current work wind grade; if the power of the wind wheel draught fan of the indoor machine is less than the set power threshold value of the current work wind grade, controlling the indoor machine to run under other work wind grades except the current work wind grade; under the other work wind grades, judging if the power of the wind wheel draught fan of the indoor machine is less than set power threshold value of the other work wind grades; if the power of the wind wheel draught fan of the indoor machine under the other work wind grades is less than the set power threshold value of the other work wind grades, judging out that dust accumulation is serious in the indoor machine. The air conditioner, and the accumulated dust detection method and the accumulated dust detection device of the air conditioner can judge if the dust accumulation is serious in the indoor machine without need for adding an additional detection device or variable, and are high in practicability and high in performance cost ratio.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a dust accumulation detection method and device of an air conditioner and an air conditioner. Background technique [0002] When the indoor unit and outdoor unit of the air conditioner operate under the condition of serious dust accumulation, the reliability of the refrigeration system will be seriously affected. [0003] In related technologies, there are usually two ways to judge the dust accumulation of the indoor unit. One is to judge the dust accumulation of the indoor unit by detecting the dust accumulation thickness of the filter screen. This method requires an additional detection device, and the other is Use complex calculations to deduce the air output of the air conditioner, and then judge the dust accumulation of the indoor unit according to the air output. This method needs to add some additional variables to detect the dust accumulation through calcula...
