and under the condition that the duration time reaches the second preset time, controlling the air conditioner to enter a defrosting mode by the defrosting control strategy.
6. The method according to any one of claims 1 to 5, further comprising, in case the air conditioner is in a defrosting mode:
acquiring the temperature of a condenser of the air conditioner, judging whether the continuous time length that the temperature of the condenser is greater than the preset temperature of the condenser reaches a third preset time length or not to obtain a fourth judgment result, and determining whether to exit a defrosting mode or not according to the fourth judgment result; alternatively, the first and second electrodes may be,
and acquiring continuous defrosting time, judging whether the continuous defrosting time reaches a fourth preset time to obtain a fifth judgment result, and determining whether to exit the defrosting mode according to the fifth judgment result.
7. An air conditioner defrosting control device is characterized by comprising:
the acquiring unit is used for acquiring the continuous operation time of the air conditioner;
the determining unit is used for determining a defrosting control strategy corresponding to the continuous operation time length;
and the control unit is used for controlling the air conditioner according to the defrosting control strategy.
8. The apparatus of claim 7, wherein the determining unit is further configured to:
determining that the continuous operation time length reaches a target time length range;
and acquiring a defrosting control strategy corresponding to the target duration range.
9. An electronic device, comprising: a processor and a memory;
the memory has stored thereon a computer readable program executable by the processor;
the processor, when executing the computer readable program, implements the steps in the method of any of claims 1-6.
10. A computer-readable storage medium, storing one or more programs, the one or more programs being executable by one or more processors to perform the steps of the method of any one of claims 1-6.
