s300: the air conditioner performs a target defrosting mode.
In this embodiment, when the air conditioner has different on-time periods, the air conditioner is in different stages. For example, when the air conditioner is just started, if the external unit of the air conditioner is slightly frosted at the moment, the frosting problem of the external unit of the air conditioner can be solved by reducing the frequency of the compressor; after the air conditioner is started for a period of time, if the external unit of the air conditioner is slightly frosted, the air conditioner can be switched to a refrigeration mode, and the air conditioner is thoroughly defrosted.
It can be understood that, according to the scheme of the embodiment, the air conditioner is controlled to enter different defrosting modes according to the starting time of the air conditioner, namely different stages of the operation of the air conditioner, so that the times of system defrosting are effectively reduced, and the experience of a user when the air conditioner is used is improved.
Further, according to the starting-up time length, determining a target defrosting mode matched with the starting-up time length in the plurality of defrosting modes comprises:

s230: and determining a target defrosting mode matched with the starting-up time length in the plurality of defrosting modes according to the starting-up time length and the difference value.
It can be understood that when the difference between the outdoor environment temperature and the outdoor panel temperature is large, it indicates that the outdoor unit of the air conditioner is frosted seriously, so that the target defrosting mode matched with the starting-up time length can be accurately determined in the plurality of defrosting modes according to the difference, and the efficiency of the control method of the invention is further improved.
Further, according to the starting-up time length and the difference value, determining a target defrosting mode matched with the starting-up time length in the plurality of defrosting modes comprises the following steps:

In this embodiment, when the starting time is less than the first time threshold, the air conditioner is in a stage of starting immediately at this time, the defrosting mode at this time may be relatively light, and only the upper limit of the frequency of the compressor needs to be reduced, if the operating frequency of the compressor is lower than the first frequency, the original frequency is maintained, the rotating speed of the fan of the internal machine is unchanged, and the compressor slowly increases the frequency and operates until the difference value is less than or equal to the second temperature threshold.
Illustratively, the first time threshold is 10 minutes, the first temperature threshold is 5 degrees celsius, the first frequency is 60Hz, the first rotational speed is 1200r/min, and the second temperature threshold is 0.
It can be understood that, at the stage of the air conditioner just starting up, the defrosting mode can be light and tiny, the air conditioner does not need to be switched into the refrigeration mode, and only the frequency of the compressor and the rotating speed of the outer motor need to be adjusted. The method of the invention effectively reduces the times of the air conditioner entering the defrosting mode and improves the system stability.
Further, according to the starting-up time length and the difference value, determining a target defrosting mode matched with the starting-up time length in the plurality of defrosting modes comprises the following steps:
s232: when the starting time is greater than or equal to a first time threshold, less than a second time threshold and the difference value is greater than or equal to a third temperature threshold, stopping the compressor, controlling the rotating speed of the motor of the outer machine to be a first rotating speed, and starting the electric auxiliary heat of the inner machine until the temperature of the outer disc is greater than or equal to a fourth temperature threshold;
wherein the third temperature threshold is greater than the first temperature threshold.
In this embodiment, when the startup duration is greater than or equal to the first time threshold and less than the second time threshold, the air conditioner is started for a period of time, the defrosting mode at this time can adopt a low-standard protection means, the compressor can be controlled to stop, the rotating speed of the motor of the outer machine is controlled to be the first rotating speed, the electric auxiliary heat is turned on by the inner machine to reduce the heat taken away by the coil pipe from the indoor space, and the air conditioner exits the defrosting mode until the temperature of the outer plate is greater than or equal to the fourth temperature threshold, and then the air conditioner resumes normal operation.
Illustratively, the second time threshold is 60 minutes, the third temperature threshold is 10 degrees celsius, and the fourth temperature threshold is 18 degrees celsius.
It is understood that the defrosting mode takes a low-standard defrosting mode after the air conditioner is operated for a certain period of time. The method of the invention can ensure that the air conditioner can effectively defrost on the premise of reducing the air conditioner entering the refrigeration mode, selects more effective defrosting means according to different conditions, has shorter defrosting time than the single defrosting time of the original defrosting logic, has shorter waiting time for a user to use, and improves the satisfaction degree of the user.
Further, according to the starting-up time length and the difference value, determining a target defrosting mode matched with the starting-up time length in the plurality of defrosting modes comprises the following steps:
s233: when the starting time is greater than or equal to a second time threshold, the difference value is greater than or equal to a fifth temperature threshold and is less than a sixth temperature threshold, controlling the air conditioner to enter a refrigeration mode at a second frequency, controlling the inner fan to be at a second rotating speed, controlling the outer fan to be at a third rotating speed, and starting the electric auxiliary heating of the inner fan until the temperature of the outer disc is greater than or equal to a fourth temperature threshold;

the fifth temperature threshold is smaller than the sixth temperature threshold, the second frequency is smaller than the third frequency, the fourth rotating speed is greater than the second rotating speed, and the fifth rotating speed is greater than the third rotating speed.
In this embodiment, when the time period for starting up the air conditioner is greater than or equal to the second time threshold, the air conditioner has been started up for a period of time, and the defrosting mode should ensure thorough defrosting. S234 compares with S233, and when the difference is larger, it indicates that the frosting of the external unit of the air conditioner is more serious, and at this time, the frequency of the compressor is higher, the rotation speed of the internal unit fan is higher, and the rotation speed of the external unit fan is higher when the air conditioner enters the cooling mode.
Illustratively, the fifth temperature threshold is 10 degrees Celsius, the sixth temperature threshold is 15 degrees Celsius, the second frequency is 40Hz, the third frequency is 60Hz, the second rotational speed is 500r/min, the third rotational speed is 1000r/min, the fourth rotational speed is 1200r/min, and the fifth rotational speed is 1200r/min.
