Accordingly, when the air passage control link 180 is controlled to rise, a portion of a flow area for air to flow between the first blowing fan 160 and the first discharge hole 120 may be selectively closed. Accordingly, air discharged from the first blowing fan 160 may be controlled to be selectively blown to a specific area.

Conversely, when the air passage control link 180 is raised via the first actuator, the other end of the penetrating member 171 fastened to the penetrating fastener 181 rises together with it, whereby the control panel integrally formed with the penetrating member 171 175 can be rotated in a direction opposite to this one direction, so that the air channel control panel can be controlled to be closed. Accordingly, when the air passage control link 180 is controlled to descend, the entirety of a flow area for air to flow between the first blowing fan 160 and the first discharge hole 120 may be opened. Accordingly, air discharged from the first blowing fan 160 may be controlled to be uniformly blown to all areas.

Also, the air passage control panel 180 may be rotated along the inner wall of the first housing 100 in the circumferential direction via the second actuator. Accordingly, the centralized air passage 190 may be controlled to rotate in the circumferential direction.
