In addition, the control unit opens the discharge unit 600 at a position adjacent to the front panel 400 when the front panel 400 moves forward, and when the front panel 400 moves to its original position (retreat), the front panel ( The discharge unit 600 at a position adjacent to 400 may be closed.

By selectively controlling the plurality of front panels 400, the blowing fan 220, and the discharge unit 600 as described above, in the cooling operation, the indoor air is air-conditioned at the top to be discharged to the upper part, and in the heating operation. The indoor air is air-conditioned at the bottom to be discharged to the bottom to quickly cool / heat the indoor air evenly.

In one embodiment of the present invention, in the sleep operation, the control unit may close the lower air outlet and open the upper air outlet in order to prevent air conditioning directly blown to the user despite the cooling / heating operation. .

On the other hand, the control unit advances the entire front panel 400 when only the front panel 400 selected to move forward among the upper and lower front panels 400 during the cooling / heating operation is not sufficient for indoor cooling / heating. You can move it.

When all the front panel 400 is moved forward, the control unit operates all the blower fans 220 disposed above and below, and the upper and lower discharge units may be selectively opened or closed.

Meanwhile, in the present invention, the control unit controls the discharge unit 600 such that the lower air discharge port 620 is opened more than the upper air discharge port 620 during the heating operation, or the upper air discharge port when the upper air discharge port is opened during the cooling operation. The discharge unit can be controlled to open more than the discharge port.

At this time, the opening ratio of the lower surface air discharge port 620 and the upper surface air discharge port 620 is preferably 7: 3 during heating operation and 3: 7 during cooling operation, respectively.

The present invention can selectively operate the plurality of separated front panel 400, the blowing fan 220, and the discharge unit 600 according to various operation modes such as cooling, heating, and sleeping operation, as well as going out and exercising. The driving mode may be selected according to a user's input through a separate input means.

Reference numerals not described in the drawings refer to the bearing part 221 for the blowing fan, the seating hook 297, the fixing protrusion 523, the locking step 524, the main frame 630 of the discharge unit, the discharge panel guide part 650, The opening and closing guide 1000, the insertion groove 1010, the driving motor fixture 1100, the body 1110, the accommodating part 1120, the mounting leg 1150, and the drain pan 1700.
