When the air conditioner is in operation, the control unit may drive the motor 16 of the fan unit 14, and the air above the air draw-in passage P and the air below the air draw-in passage P may be drawn into the air draw-in passage P. The air above the air draw-in passage P may be introduced between the left side body 32A and the right side body 32B of the front panel 30 through an opened upper side of the front panel 30, and therefrom to the air inlet 4. The air below the air draw-in passage P may be introduced between the left side body 32A and the right side body 32B of the front panel 30 through an opened lower side of the front panel 30, and therefrom to the air inlet 4. The air drawn to the air inlet 4 may make heat exchange at the heat exchanger 15, and may be discharged to the side air outlet 6. The air discharged to the side air outlet 6 may be guided by the first plate 25 and the second plate 26 of the side discharge vane 20, so as to be discharged to the side of the side body 32 of the front panel 30. The air guided by the side discharge vane 20 may not be introduced to the air draw-in passage P blocked by the side body 32, but may be introduced to the room.
When the air conditioner is not in operation, the control unit may turn off the motor 16. And, control unit may control the discharge vane drive motor 23 in the air outlet close mode. The control unit may control both of the left side discharge vane drive motor 23A and the right side discharge vane drive motor 23B in the air outlet close mode. The side discharge vane 20 may be turned in a direction opposite to a direction when the air outlet is opened, and may be turned to a position at which the side discharge vane 20 is in close contact with the side 3 of the body 2. The control unit may make the front panel drive mechanism 40, not to operate, but to standby, while the control unit controls the discharge vane drive motor 23 in the air outlet close mode.
After the side discharge vane 20 is turned to be in close contact with the side 3 of the body 2, the control unit may control the front panel drive mechanism 40 in the second mode. When the front panel drive mechanism 40 is in the second mode, the front panel 30 may move backward, when the side body 32 may move to the portion of the side of the side discharge vane 20. The side body 32 may be brought into contact with the second plate 26 and may move to the side of the second plate 26 as the side body 32 moves backward together with the front body 31, gradually. Since the second plate 26 is in close contact with the side 3 of the body 2 before the front panel 30 is moved, the second plate 26 does not interfere with movement of the side body 32, and the side body 32 may cover the second plate 26 at a side of the second plate 26. When the front panel 30 moves backward, the side body 32 may shade the gap between the front body 31 and the body 2, and the second plate 26 can be protected by the side body 32.

The user may place the filter 50 in the gap S between the body 2 and the panel body 33, and slidably mount the filter 50 in the body 2 in the lateral direction. After mounting the filter to the body 2, the user may mount the front cover 34 to the panel body 33, such that the side body 32 of the front cover 34 covers the gap S between the body 2 and the panel body 33, to enable to cover a portion of the side discharge vane 30 and the side 51 of the filter 50, altogether.
The air conditioner may be operated in a state the front cover 34 is mounted to the panel body 33, and, alike the preferred embodiment of the present invention, the front panel drive mechanism 40 may move the front panel 30 forward. When the front panel 30 is moved forward, the side body 32 may be moved forward to a position at which the side body 32 covers the side edge 51 of the filter 50, but not the side discharge vane 20. After the front panel 30 is moved forward, the discharge vane drive motor 23 may turn the side discharge vane 20 such that the side discharge vane 20 is projected to a side of the body 2.
Alike the preferred embodiment of the present invention, when the air conditioner is turned off, the discharge vane drive motor 23 may turn the side discharge vane 20 to be in close contact with the side 3 of the body 2. Alike the preferred embodiment of the present invention, after driving the discharge vane drive motor 23, the front panel drive mechanism 40 may move the front panel 30 backward. When the front panel 30 is moved backward, the side body 32 may be moved backward from a position at which the side body 32 covers the side edge 51 of the filter 50, but not the side discharge vane 20, or to a position at which the side body 32 covers a portion of the side discharge vane 20 and the side edge 51 of the filter 50, altogether.
As has been described, the air conditioner of the present invention has the following advantages.
The front panel can protect the side discharge vane, and the side appearance of the air conditioner becomes neat and tidy.
And, infiltration of the foreign matter through a gap between the side discharge vane and the body can be minimized to enable to maintain a clean air conditioner.
And, no additional outside door or outside cover is required for covering the discharge vane, enabling to protect the discharge vane with a simple structure.
And, since the front panel does not interfere with the side discharge vane from turning when the air conditioner is in operation, and the side discharge vane does not interfere with the front vane from moving backward when the air conditioner is not in operation, the front panel and the side discharge vane can be operated securely without being damaged.
Although the air conditioner according to the present invention has been described with reference to the illustrated drawings, it will be apparent to those skilled in the art that the present invention is not intended to be limited to the above-described embodiment and drawings, and various changes or modifications may be made therein without departing from the scope and the technical sprit of the present invention.
