  • the vertical wind that sends the air discharged through the outlet in a direction perpendicular to the ground may be formed.
  • the wind adjuster 430 rotates at the third rotation speed corresponding to between the first rotation speed and the second rotation speed, the inclined wind that sends the air discharged through the outlet into between the indirect wind and the vertical wind may be formed.
  • the air conditioner according to the fourth embodiment may also send the air discharged from the outlet 424 in the first direction D1, the second direction D2, and the third direction D3, according to the first rotation speed, the second rotation speed, and the third rotation speed of the wind adjuster 430.
  • the control method of the air conditioner according to FIGS. 11 to 13 may be applied to the air conditioner according to the second to fourth embodiments.
  • the airflow of the air discharged to the living area and the non-living area of the occupant can be set differently in the indoor space, thereby enhancing the comfort level in the living area of the occupants.
  • the desired temperature can be reached quickly in the living area by adjusting the relative height of the airflow discharged from the indoor space to the living area of the occupant and the airflow discharged to the non-living area.
  • the discomfort caused by the direct friction of the air discharged to the occupant can be minimized by adjusting the relative height of the airflow discharged to the living area and the airflow discharged to the non-living area.
  • the accuracy of the living area determination can be enhanced by classifying the living area and the non-living area based on the accumulated position detection of the human body.
