The current on the flap should be maintained within a stable initial value range during normal operation, i.e., when no foreign object is inserted into the outlet. When a foreign object, such as a human hand, extends into the air outlet, the current value on the swing blade fluctuates greatly under the touch of the foreign object. Therefore, whether a foreign object extends into the air outlet or not can be judged through the fluctuation of the current on the swinging blade, and then corresponding protective measures are carried out.
The fluctuation value of the current on the swinging blade when the foreign object touches can be obtained in advance through a test and the like. And then the fluctuation range of the current on the swinging blade when the foreign object is judged to extend into the air outlet can be preset. Specifically, a current fluctuation threshold value can be set, and when the current on the swing blade exceeds the threshold value range, it is judged that a foreign object enters the air outlet.
According to the air conditioner operation protection method provided by the embodiment, the current is supplied to the swinging blade of the air outlet, whether a foreign object extends into the air outlet is judged by monitoring the change of the current on the swinging blade, and then the starting of the protection measures is controlled; the protection method is convenient to operate, changes of the existing air outlet structure are small, and the practicability is high.
