On a certain wind-speed gear when normal rotation, constant resisting force, when wind deflector is by outer force effect, resistance increases.When wind deflector is by outer
When force effect reaches certain value, electric current will increase to certain value accordingly, in this way, the current value and wind deflector are by external force
There are certain correspondences between effect.Thus, it is run by detecting air conditioner air deflector driving motor on same wind-speed gear
When current value, and according to the relationship of the current value and predetermined current that detect can to wind deflector whether by outer force effect and
Judged by force effect size.
Step S3 compares the wind deflector driving motor running current of detection with the predetermined current of corresponding wind-speed gear
Compared with if wind deflector driving motor running current illustrates that wind deflector by outer force effect, enters step more than or equal to predetermined current
Otherwise S4 enters step S2, air-conditioning continues normal operation.
Step S4 judges whether to receive off signal, if so, entering step S5, otherwise, enters step S6.
The off signal of the present embodiment can be the remote signal that air-conditioning is sent to by remote controler.
Step S5, control wind deflector driving motor stops operating, at this point, wind deflector reaches closed position.
Step S6 illustrates wind deflector by other outer force effects, driving wind deflector driving electricity if not receiving off signal
Machine drives wind-guiding sheet reset, after reset, enters step S2, continues to run with.
Wind deflector reseting procedure is in the present embodiment, and driving motor driving wind deflector turns to reference position, wind deflector from
Reference position rotates again, recalculates step number.
During the present embodiment operation of air conditioner, if carrying out wind-speed gear handover operation, re-executed from step S1.
