4. The method according to claim 1, characterized in that, The step of determining the target operating mode of the air conditioner based on the indoor ambient temperature, the power outage duration, and the user-set temperature further includes: Calculate the temperature difference between the indoor ambient temperature and the user-set temperature, and determine whether the temperature difference is not greater than a preset temperature difference threshold. If so, the target operating mode of the air conditioner is determined to be the memory setting mode.

5. The method according to claim 4, characterized in that, The step of determining the target operating mode of the air conditioner based on the indoor ambient temperature, the power outage duration, and the user-set temperature further includes: If the temperature difference is greater than the preset temperature difference threshold, the target operating mode of the air conditioner is determined to be the preset cooling operating mode.

6. The method according to claim 1, characterized in that, The step of controlling the air conditioner to operate continuously according to the target operating mode includes: When the air conditioner operates in the preset cooling mode, the user-set temperature is set to 26°C, the air deflector is controlled to rotate within a specified angle range, the indoor unit motor speed is controlled to medium speed, the outdoor unit motor speed is controlled to 920 r / min, and the compressor is controlled to operate according to a preset curve; wherein, the specified angle range is [53°, 63°].

7. The method according to claim 1, characterized in that, The method further includes: If the remote control command is received within the specified time period, the air conditioner is controlled to operate according to the remote control command.

8. A control device for resuming power after an air conditioner has been powered off, characterized in that, include: The power-on duration acquisition module is used to acquire the power-on duration after the air conditioner is powered off and then powered on again within a specified time period; wherein the specified time period is from 18:00 of the previous day to 07:00 of the next day. The simplified cooling mode entry module is used to control the air conditioner to enter the simplified cooling mode if no remote control command sent by the user is received after the power-on time reaches a preset first time. The simplified cooling mode is used to represent the cooling operation mode that is automatically started when the air conditioner is powered on again after a power outage. The simplified cooling mode operation module is used to control the air supply mode of the indoor unit of the air conditioner in the simplified cooling mode, and control the air guide damper of the indoor unit to rotate cyclically according to a preset rotation mode until the air supply operation time reaches a preset second time; and to control the air conditioner to switch to dehumidification mode operation until the dehumidification operation time reaches a preset third time, and to obtain the indoor ambient temperature at this time.
