[ first drive section ]
The first driving unit 180 may be variously modified within the technical idea of being connected to the first guide unit 150 and supplying rotational power to rotate the first guide unit 150. The first driving unit 180 uses a stepping motor that rotates at a set angle, and the main body of the first driving unit 180 is fixed to the front discharge unit 120. Since the output shaft of the first driving unit 180 is connected to the rotation center of the first guide unit 150, the first guide unit 150 is rotated by the operation of the first driving unit 180, and thus the direction of the air flow discharged from the front air blowing module 130 can be controlled.
[ second drive section ]
The second driving unit 190 may be variously modified within the technical idea of being connected to the second guide unit 160 and supplying rotational power to rotate the second guide unit 160. The second driving unit 190 uses a stepping motor that rotates at a set angle, and the main body of the second driving unit 190 is fixed to the housing bracket 36. Since the output shaft of the second driving unit 190 is connected to the rotation center of the second guide unit 160, the second guide unit 160 is rotated by the operation of the second driving unit 190, and thus the direction of the air flow discharged from the front air blowing module 130 can be controlled.
