The invention provides a variable-angle electric heating control method and an air conditioner applying the variable-angle electric heating control method. At least two sections of heat exchangers arearranged in a surrounding mode, the included angle is smaller than 90 degrees, and electric heating is carried out under the driving of a stepping motor. The method comprises the following steps thatthe state of an electric heating switch is called, and if the electric heating switch works, the air supply temperature of an air outlet is collected; the air supply temperature difference between the air outlet air supply temperature and the air conditioner set temperature is calculated, and if the air supply temperature difference is smaller than the first set value, the stepping motor drives the electric heating switch to rotate to the first working position; and if the air supply temperature difference is larger than the first set value, the stepping motor drives the electric heating to rotate in sequence to the initial working position and keep the initial working position; and when the electric heating rotates to the first working position, the first heat dissipation surface of theelectric heating switch is kept horizontal, and when the electric heating device rotates to the initial working position, the first heat-dissipation surface and the second-section heat exchanger are parallel to each other. The method has the advantages of being high in flexibility and good in user experience.
