S4. Determine whether the air conditioner cleaning condition is reached based on the accumulated running time of the motor and the motor power attenuation value. If yes, issue an air conditioner cleaning prompt. In this embodiment, the air conditioner cleaning condition includes a first determination condition, a second determination condition, and a third determination Conditions; the first judgment condition is: the cumulative running time of the motor ≥ the first preset time, and the motor power attenuation value ≥ the first preset attenuation threshold, wherein the first preset time can be selected from 400 to 700h, and can further be 500h , The first preset attenuation threshold can be selected as 20%; the second judgment condition is: the cumulative running time of the motor ≥ the second preset time, and the motor power attenuation value ≥ the second preset attenuation threshold, where the second preset time Optional 700 ~ 900h, further 800h, the second preset attenuation threshold can be selected as 10%; the third judgment condition is: the cumulative running time of the motor ≥ the third preset time, where the third preset time is optional 900 ～ 1100h, further 1000h, when the air conditioner reaches any one of the first judgment condition, the second judgment condition, and the third judgment condition, the air conditioner cleaning prompt will be issued, prompting Household cleaning air-conditioning. In addition, in this embodiment, since the cumulative running time of the motor in the first, second, and third determination conditions is a parameter related to time, and the time has continuity, therefore, does the air conditioner issue an air conditioner cleaning prompt , You can also make judgments in sequence according to the first judgment condition, the second judgment condition, and the third judgment condition to further improve the judgment accuracy, specifically:

When the cumulative running time of the motor and the motor power attenuation value do not meet the first judgment condition, it is judged whether the cumulative running time of the motor and the motor power attenuation value meet the second judgment condition, if the cumulative running time of the motor and the motor power attenuation value meet the second judgment When the condition is met, it is considered that the air conditioner has reached the condition for cleaning the air conditioner, and the air conditioner cleaning prompt is issued;

When the cumulative running time of the motor and the motor power attenuation value do not meet the first and second judgment conditions, it is determined whether the cumulative running time of the motor and the motor power attenuation value meet the third judgment condition. When the value meets the third judgment condition, it is deemed that the air conditioner has reached the air conditioner cleaning condition, and an air conditioner cleaning prompt is issued.

The air conditioner cleaning reminding control method of this embodiment monitors the motor power and cumulative running time of the machine during the current operating time of the air conditioner, and determines whether the air conditioner is dirty or clogged according to the cumulative operating time of the motor and the motor power attenuation value, which can accurately and timely remind The user cleans the air conditioner to improve the user experience. Dirty filter clogging and a large amount of dust accumulation in the air ducts, wind blades or sweep blades will affect the air quality of the air conditioner, which will affect the user experience. Therefore, the motor is used in this embodiment The power attenuation value is used to determine whether the air conditioner is dirty and blocked, and can be used to determine whether the filter screen, air duct, fan blade or sweep blade is cleaned. Moreover, in this embodiment, the multi-gradient judgment method is used to determine whether the air conditioner is cleaned, which can control whether the air conditioner is cleaned more finely, so that the entire control process can be closer to the actual situation of the air conditioner is blocked, and the user experience is improved. The setting of a specific range of the preset time of the cumulative running time of the motor and the preset attenuation threshold of the motor power attenuation value in the gradient determination can further improve the accuracy of the determination. In addition, in this embodiment, in order to make the air-conditioning cleaning control more precise and to make the judgment result more accurate, the multi-gradient judgment is not limited to the above-mentioned three-gradient judgment, that is, the first judgment condition, the second judgment condition, and the third judgment condition. You can also set more decision gradients according to the actual situation.

In this embodiment, in step S4, it is determined whether the air conditioner cleaning condition is reached based on the accumulated running time of the motor and the motor power attenuation value. If yes, an air conditioner cleaning prompt is issued, which specifically includes:

If the cumulative operating time and motor power attenuation value of the motor reaches the air conditioner cleaning condition, continue to monitor the coil temperature of the evaporator, and Determine whether the evaporator defrosting condition is reached according to the coil temperature. If the coil temperature reaches the evaporator defrosting condition, the evaporator is defrosted. After the defrosting is completed, it is re-judged based on the accumulated operating time of the motor and the motor power attenuation value. Reaching the air conditioner cleaning conditions can prevent misjudgment caused by evaporator icing and further improve the accuracy of air conditioner cleaning judgment. In addition, in this embodiment, the defrosting judgment of the evaporator may be performed first, and then whether the air conditioner cleaning condition is reached can be judged based on the accumulated running time of the motor and the motor power attenuation value.

S5. Monitor the start and stop of the air conditioner cleaning key, and determine whether the air conditioner cleaning key is activated. If yes, clear the cumulative running time of the motor; if not, continue to monitor the motor power attenuation value and determine whether the motor power attenuation value meets the motor cumulative operation The zero-clearing condition of time, wherein the zero-clearing condition of the cumulative running time of the motor is: motor power attenuation value <third preset attenuation threshold, where the third preset attenuation threshold can be selected as 5%, and in order to improve the accuracy of monitoring The monitoring time for continuous monitoring of the power attenuation value of the motor is continuous monitoring for 10 to 20s, optionally 15s;

If the motor power attenuation value meets the condition for clearing the cumulative running time of the motor, the cumulative running time of the motor is cleared.

In this embodiment, after cleaning the air conditioner, the user can determine the cleaning result of the air conditioner by monitoring whether the user presses the cleaning key and the motor power attenuation value, which can further improve the accuracy of real-time monitoring of the air conditioner cleaning degree and the timeliness of the air conditioner cleaning.
