By operating the second motor 138, the pair of covers 112a and 112b can be placed in contact with each other or spaced apart from each other. The pair of inner dampers 110 are arranged at the third position (P3) where the inner ends 114d of each cover 112a and 112b are spaced apart from each other, as shown in Figures 13a and 13b, or as shown in Figures 14a and 14b. As shown, the inner ends 114d of each cover 112a and 112b may be disposed at the fourth position P4, where they contact each other. Since the third position (P3) and the fourth position (P4) are based on the arrangement of the inner damper 110, the first position (P1) and the second position (P2) related to the arrangement of the outer dampers (90a, 90b) ) can be applied regardless.

Referring to Figures 13a and 13b, when the inner damper 110 is in the third position (P3), the covers (112a, 112b) close the first discharge port (83). When the inner damper 110 is in the third position (P3), the covers 112a and 112b are disposed below the grill 88 disposed at the first discharge port 83. That is, when the inner damper 110 is in the third position (P3), the inner damper 110 blocks the air flowing upward by the blowing fan 30 from flowing into the first outlet 83.

Accordingly, the air flowing upward due to the operation of the blowing fan 30 flows through the hole 128 formed in the first support plate 126 and the space formed inside the cover body 72 at the front and rear of the supporter 124. It can flow into the second flow path 62 of the side body 60. The air flowing along the flow path of the side body 60 is discharged rearward through the second discharge port 64, and can flow forward along the outer surface of the side body 60 by the first guider 74. .

Referring to Figures 14a and 14b, when the inner damper 110 is in the fourth position (P4), the covers (112a, 112b) open the first discharge port (83). When the inner damper 110 is in the fourth position P4, the inner ends 114d of the pair of covers 112a and 112b are placed in contact with each other. Accordingly, a space through which air flows is formed between the side ends 114a of the covers 112a and 112b and the inner surface of the cover body 72.

The blowing fan 30 rotates to discharge air in the upper centrifugal direction. Accordingly, the air flowing inside the cover body 72 mainly forms an airflow on the inner surface of the cover body 72. Accordingly, air flowing along the cover body 72 may flow along the inner surface of the cover body 72 to the first outlet 83. However, some of the air flow occurs in the space between the covers (112a, 112b) and the first discharge port (83), the front and rear ends (114b) and rear ends (114c) of the covers (112a, 112b), and the cover body (72). It can flow into the second flow passage 62 inside the side body 60 through the space between. Accordingly, some flow of air may be formed through the second outlet 64, but the flow rate and flow rate of the air flowing through the first outlet 83 are different from the flow rate of the air flowing through the second outlet 64. Since it is formed faster and greater than the flow rate, a discharge airflow can be formed through the first discharge port 83.

The air flowing through the first outlet 83 can ride the outer surface of the side body 60 and flow upward by the second guider 84.
