When one of the first air in/out side P1 and the second air in/out side P2 faces the inside I of the body, the other one may face the inside of the room R. In a wind direction mode in which the first air in/out side P1 faces the inside I of the body 6, the second air in/out side P2 may face the inside of the room R, and, as shown in FIGS. 1 and 2, the air may be discharged to the inside of the room passed through in an order of the first air in/out side P1, the air guide passage P3, and the second air in/out side P2, and discharge thereof may be guided in a direction the wind direction control member 22 guides the air.

The wind direction controller of claim 12, wherein the driving mechanism (24', 24") has a divergent discharge mode in which the first air in/out side (P1) of each of the plurality of the wind direction control members (22', 22") faces an inside (I) of the body (6) and the second air in/out side (P2) of each of the plurality of the wind direction control members (22', 22") faces an inside of the room (R),
a convergent discharge mode in which the first air in/out side (P1) of each of the plurality of the wind direction control members (22', 22") faces an inside of the room (R) and the second air in/out side (P2) of each of the plurality of the wind direction control members (22', 22") faces the inside (I) of the body (6), and
a deflected discharge mode in which the first air in/out side (P1) of one of the plurality of the wind direction control members (22', 22") faces an inside (I) of the body (6) and the second air in/out side (P2) of the other one of the plurality of the wind direction control members (22', 22") faces the inside (I) of the body (6),
wherein the driving mechanism (24', 24")performs one of the divergent discharge mode, the convergent discharge mode, and the deflected discharge mode, selectively.
The wind direction controller of claim 13, wherein the deflected discharge mode includes a left direction deflected discharge mode and a right direction deflected discharge mode for guiding air discharge in directions opposite to each other.
An air conditioner comprising the wind direction controller as claimed in one of claims 1 to 14.
