The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not
For limiting the application.
In one embodiment, as shown in Figure 1, providing a kind of rotation speed of fan control method, it is applied to place in this way
It is illustrated, includes the following steps for reason device：
Step S110：The real-time current value of the motor of acquisition blower and real-time revolving speed.
Specifically, processor detects motor real-time current value Ia, the real-time current value Ia table of motor every preset time △ t
The load of motor is levied, revolving speed is the circle number turned in the object unit time to move in a circle circumferentially around the center of circle, when motor
When load becomes larger, the revolving speed of corresponding motor also be will increase.
Step S120：It is compared to obtain comparison result according to real-time current value and default cut-off current.
Specifically, real-time current value Ia and default cut-off current Ib is compared, obtains comparison result, is judged according to comparison result
Blower whether overload operation.
Step S130：Speed controling signal is exported according to comparison result and real-time revolving speed.
Specifically, speed controling signal is used to control the revolving speed of the motor of blower.Further, judged according to comparison result
The motor of blower whether overload operation, adjust the real-time revolving speed of motor, prevent outer machine blower from seriously leading to electricity because of outer machine frosting
Machine overload operation.It is appreciated that the speed controling signal of output is also different, in this reality according to the difference of comparison result
It applies in example, speed controling signal includes reduction of speed control signal, rising film condensation signal, shutdown control signal and rated speed control letter
