when the high pressure of the outdoor unit is greater than or equal to a second preset pressure and less than the first preset pressure, calculating the angular speed according to the high pressure of the outdoor unit, the rated angular speed, the first preset pressure and the second preset pressure;
and when the high pressure of the outer machine is smaller than the second preset pressure, the fan air sweeping mode is exited.
7. The method of claim 6, wherein calculating the angular velocity based on the outer machine high pressure, the rated angular velocity, the first preset pressure, and the second preset pressure comprises:
the angular velocity is calculated using the following formula:
where ω denotes the angular velocity, P denotes the outer machine high pressure, P1Represents the second preset pressure, P2Representing said first predetermined pressure, P2＞P1，ω1Representing the nominal angular velocity.
8. An outdoor unit control device for an air conditioner, comprising:
the high-voltage monitoring module is used for monitoring the high voltage of an external unit of the air conditioner in real time;
the starting module is used for starting a fan wind sweeping mode when the high pressure of the outer machine is greater than or equal to a first preset pressure;
and the determining module is used for determining the deviation angle of the main shaft of the fan blade driving motor and the main shaft of the wind sweeping support motor according to the outdoor environment temperature in the wind sweeping mode of the fan, and determining the angular speed of the wind sweeping support motor driving the wind sweeping support to rotate according to the high voltage of the outer machine.
9. An outdoor unit for an air conditioner, comprising: the outdoor unit control device of claim 8.
10. The outdoor unit of claim 9, further comprising: the fan blade, the fan blade driving motor, the wind sweeping bracket and the wind sweeping bracket motor are arranged on the fan blade;
the fan blades are arranged on a main shaft of the fan blade driving motor, and rotating shafts are arranged on two sides of the fan blade driving motor and are used for being connected with round holes in the wind sweeping support; and a main shaft of the wind sweeping support motor is fixedly connected with the wind sweeping support.
11. A computer-readable storage medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the outdoor unit control method of any one of claims 1 to 7.
