Abstract
An air duct conversion device comprises an air duct baffle installed on the air duct in a manner of capable of relatively rotating; an output shaft of a motor is connected with the air duct baffle through a linkage mechanism, to drive the air duct baffle to rotate around the shaft through the linkage mechanism in the rotating process of the output shaft of the motor, such that the air duct baffle switches to move between a first position and a second position. Through the above setting, under the driving of the linkage mechanism, the air duct baffle in the air duct correspondingly swings and rotates along with the rotation of the output shaft of the motor, to control the corresponding opening and closing of different openings in the air duct, to achieve the purpose of controlling the reversal of direction of the air flow in the air duct.
