step 1), the air conditioner 1 is started, the user information receiving module 1051 receives the setting made by the user to the air conditioner 1, and the setting is controlled by the fan rotating speed control module 1053; the actual target rotational speed R of the indoor fan 104 is set as an indoor fan rotational speed parameter Rs set by the user;
step 2) when the actual rotating speed of the indoor fan 104 reaches the indoor fan rotating speed parameter Rs set by the user, judging the conditions: ps-P is more than or equal to delta P, and the dust deposition degree of the air conditioner 1 is judged; wherein Ps is a power value of the indoor unit when the preset indoor fan rotating speed reaches an indoor fan rotating speed parameter Rs set by a user, P is a power value P of the indoor unit when the rotating speed of the indoor fan 104 acquired by the fan operation information acquisition module 1052 reaches an actual target rotating speed R, and Δ P is a preset power judgment threshold;
step 3) if the determination condition in step 2) is met, determining that the dust on the air conditioner 1 reduces the air supply quantity and the heat exchange efficiency of the indoor unit 10, and increasing the actual target rotating speed R of the indoor fan 104 through the fan rotating speed control module 1053 until the determination condition is not met or the actual target rotating speed R of the indoor fan reaches the self-set upper limit Rmax; if the judgment condition in the step 2) is not met, determining that dust on the air conditioner has no influence or little influence on the air output and the heat exchange efficiency of the indoor unit, and continuously operating the indoor fan by taking the set target rotating speed Rs as the actual target rotating speed R of the indoor fan;
and step 4), the indoor fan 104 operates at the adjusted actual target rotating speed R until the user changes the setting or the air conditioner is turned off.
By the arrangement, in the running process of the air conditioner, if more dust is on the air conditioner, the ventilation of an indoor unit can be influenced, so that the air output of the indoor fan after the indoor fan reaches the target rotating speed is reduced, the load of the indoor fan is reduced due to the reduction of the air output, the power of the indoor fan reaching the target rotating speed is reduced due to the reduction of the load of the indoor fan, and the air output and the heat exchange efficiency of the air conditioner can be reduced even if the indoor fan reaches the target rotating speed preset by a user, so that the user experience is reduced; the control method ensures that the air supply volume and the heat exchange efficiency of the air conditioner can be still ensured even if the air conditioner is in a dust accumulation state by controlling the power of the indoor fan, so that the user is prevented from frequently cleaning an air filter screen or an indoor heat exchanger, and the use experience of the user is further improved.
In this embodiment, in the step 1), before setting the actual target rotation speed R of the indoor fan 104, it is determined whether a corrected rotation speed parameter Rs 'corresponding to the indoor fan rotation speed parameter Rs set by the user exists in the operation state information storage module 1054, if the corrected rotation speed parameter Rs' exists, the actual target rotation speed R of the indoor fan 104 is set as the corrected rotation speed parameter Rs ', and if the corrected rotation speed parameter Rs' does not exist, the actual target rotation speed R of the indoor fan 104 is set as the indoor fan rotation speed parameter Rs set by the user; the corrected rotating speed parameter Rs' is the result of the adjustment of the rotating speed parameter Rs of the indoor fan set by the user in the prior operation process of the air conditioner. So set up, the adjustment process of optimal control mode reduces indoor fan rotational speed adjustment required time.
In this embodiment, in step 2), before executing the determination condition, the stable state of the indoor fan after the rotation speed of the indoor fan 104 reaches the actual target rotation speed R is determined; the determination condition is executed after the indoor fan 104 is stably operated. So set up, provide a mistake proofing mechanism, avoid because the fluctuation of indoor fan power, lead to the judgement error of air conditioner 1 to the laying dust degree. Further, the steady state of the indoor fan 104 is determined by: when the rotating speed of the indoor fan 104 reaches the actual target rotating speed, the power value of the indoor fan 104 in the 30s is not less than 95% of the power of the indoor fan at the actual target rotating speed.
In this embodiment, in step 3), the actual target rotation speed R after the indoor fan 104 is adjusted is set as the corrected rotation speed parameter Rs ', and the corrected rotation speed parameter Rs' corresponding to the indoor fan rotation speed parameter Rs set by the user is stored in the operation state information storage module 1054. So set up, for next time indoor fan operation provides the reference, the indoor fan of the quick adjustment of being convenient for.
In this embodiment, in the step 3), if the rotating speed of the indoor fan reaches Rmax, the value of the statistical parameter t is increased by 1, and is updated and recorded in the operating state information storage module 1054; when the statistical parameter t is greater than the preset parameter beta, displaying a corresponding mark on the air conditioner to remind a user; after the air conditioner 1 is cleaned, the statistical parameter t is reset to zero. With such arrangement, when the rotating speed of the indoor fan 1 reaches the maximum, it indicates that the air supply amount of the air conditioner 1 cannot be ensured; the setting of the preset parameter beta has the function of error prevention. Furthermore, during the operation of the air conditioner, the statistical parameter t can only be increased once. So set up, avoid the repeated accumulation of parameter, make the air conditioner continuously report to the police. Further, the preset parameter β is set to 5.
In this embodiment, if the air conditioner is cleaned, the data stored in the operating state information storage module 1054 is cleared after the cleaning.

5. The dust removal control method of an air conditioner according to claim 1, wherein: in the step 3), the adjusted actual target rotating speed R is set as a corrected rotating speed parameter Rs ', and the corrected rotating speed parameter Rs' corresponding to the indoor fan rotating speed parameter Rs set by the user is stored in the operating state information storage module (1054).
6. The dust removal control method of an air conditioner according to claim 1, wherein: in the step 3), if the rotating speed of the indoor fan (104) reaches Rmax, the value of the statistical parameter t is increased by 1, and the statistical parameter t is updated and recorded in the running state information storage module (1054); when the statistical parameter t is greater than the preset parameter beta, displaying a corresponding mark on the air conditioner (1) to remind a user; after the air conditioner (1) is cleaned, the statistical parameter t returns to zero again.
7. The dust removal control method of an air conditioner according to claim 6, wherein: during the operation of the air conditioner (1), the statistical parameter t can only be increased once.
8. The dust removal control method of an air conditioner according to claim 6, wherein: the preset parameter beta is set to 5.
9. The dust removal control method of an air conditioner according to claim 1, wherein: if the air conditioner (1) is cleaned, the data stored in the operating state information storage module (1054) is cleared after the cleaning.
10. An air conditioner adopting a dust removal control method of an air conditioner according to any one of claims 1 to 9, characterized in that: the outdoor unit comprises a controller (105), an indoor unit (10), an outdoor unit (20) and a refrigerant connecting pipe, wherein the indoor unit (10) comprises an indoor heat exchanger (101) and an indoor fan (104), the outdoor unit (20) comprises a compressor (201), a four-way valve (202), an outdoor heat exchanger (203) and an outdoor fan (207), the compressor (201), the four-way valve (202), the outdoor heat exchanger (203) and the indoor heat exchanger (104) are connected through the refrigerant connecting pipe and form a loop, the controller (105) comprises a user information receiving module (1051), a fan running information acquisition module (1052), a fan rotating speed control module (1053) and a preset information storage module (1055) for storing preset information.
