Fig. 1 is a flowchart illustrating a self-cleaning control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 1, the self-cleaning control method of an air conditioner according to an embodiment of the present invention includes the steps of:
s1, acquiring the ambient temperature and the ambient humidity after the air conditioner enters the self-cleaning mode, wherein the self-cleaning mode includes a condensation phase.
It should be noted that the ambient temperature and the ambient humidity may refer to an indoor ambient temperature and an indoor ambient humidity, and may also refer to an outdoor ambient temperature and an outdoor ambient humidity.

It can be understood that, when the amount of the condensed water is constant, the ambient humidity is higher, and the difference between the ambient temperature and the temperature of the indoor heat exchanger is higher, the first operation time period t1 is shorter; the smaller the ambient humidity and the smaller the difference between the ambient temperature and the indoor heat exchanger temperature, the larger the first operation time period t 1. Therefore, after the air conditioner enters the self-cleaning mode, the ambient temperature and the ambient humidity are detected firstly, according to the ambient temperature and the ambient humidity, the mapping relation between the amount of condensed water and the refrigerating operation time length, namely the first operation time length t1 can be established, and then the first operation time length t1 can be determined through the mapping relation between the amount of condensed water and the first operation time length t 1.

The second operation time period t2 may be 10min, and may be specifically determined according to the type of the air conditioner.
Further, according to an embodiment of the present invention, when the air conditioner is in a frost stage, the first fan and the second fan are also controlled to reduce the rotation speed, or the first fan and the second fan are controlled to stop operating. Wherein the compressor frequency remains unchanged, i.e. still runs at the highest frequency.
It can be understood that the indoor heat exchanger can be frosted by controlling the first fan and the second fan to reduce the rotation speed or controlling the first fan and the second fan to stop running.
According to an embodiment of the present invention, after the defrosting stage, the self-cleaning stage of the air conditioner further includes a defrosting drying stage, and the method further includes: when the time of refrigerating operation of the air conditioner in the defrosting stage reaches a second operation time t2, controlling the air conditioner to enter a defrosting and drying stage; and when the air conditioner is in the defrosting and drying stage, controlling the air conditioner to perform heating operation until the time for the air conditioner to perform heating operation in the defrosting and drying stage reaches a third operation time period t 3.
It should be noted that, when the air conditioner is in the defrosting and drying stage, the first fan and the second fan may not be controlled to operate, or the first fan and the second fan may be controlled to operate simultaneously, wherein the rotating speeds of the first fan and the second fan may be both p%, and the value range of p may be 1-5.
It can be understood that after the defrosting stage is finished, the air conditioner enters a defrosting and drying stage, and the air conditioner is controlled to perform heating operation so as to defrost and dry the indoor heat exchanger. And when the time for heating operation of the air conditioner in the defrosting and drying stage reaches a third operation time period t3, controlling the air conditioner to exit the self-cleaning mode, and restarting the air conditioner to enter the working mode set by the user.
Wherein the third period of operation t3 is determined based on the ambient humidity, according to an embodiment of the present invention.
It can be understood that the third operation time period t3 is in positive correlation with the indoor environment humidity, that is, the larger the indoor environment humidity is, the larger the third operation time period t3 is, the smaller the indoor environment humidity is, and the smaller the third operation time period t3 is, so that after the environment humidity is obtained, the third operation time period t3 can be determined according to the environment humidity.
Therefore, the first operation time of the condensation stage is determined through the ambient temperature and the ambient humidity and the target mapping relation, the third operation time of the defrosting and drying stage is determined through the ambient humidity, the second operation time of the defrosting stage is determined through the specific model of the air conditioner, the time distribution is more reasonable and intelligent, and the indoor heat exchanger can be cleaned more thoroughly.
