  • the forward/backward rotation of the discharge panel 610 with reference to the case 200 to open/close the discharge flow passage 900 along a rear side of the discharge panel 610 enables indirect discharge of hot air in heating operation while the indirect hot air discharge does not interfere with an air inflow from front, thereby resolving the unpleasant feeling of the user.
  • the air conditioner of the present invention has the following advantages.
  • an adequate flow rate of room air can be secured at the heat exchanger, flow passage open/close control for various modes is convenient, the front panel moves stably, and uniform spreading of the air being discharged can be induced in cooling/heating operation while the air conditioner is not limited by an installation height of the air conditioner substantially.
  • flow resistance of air introduced from a room can be reduced, to make upward/downward discharge smoother, and the indirect discharge of hot air while the indirect discharge of hot air does not interfere with the inflow of air from front resolves user unpleasant feeling.
  • the driving unit having a combination of the rack rail connected to every separated front panel and the pinion permits close and smooth movement of the front panels in forward/backward horizontally, and accurate securing at a limited position.
