Referring to Figs. 12, 17 and 19, when the power section 720 is operated in the counterclockwise direction as viewed from the rear and the upper side, the upper and lower rack gear portions 746 The first slide block 742 moves to the left side and the second slide block 744 moves to the right side.

The pivoting link member 756 is rotated by the latching shaft 758 inserted into the latching groove portion 752 in accordance with the movement of the first slide block 742 to the left and the pivoting member 754 is rotated clockwise The right vertical blade 710 also rotates in the clockwise direction, and the front end of the vertical blade 710 spreads in the right direction.

When the pivotal link member 756 is rotated by the latching shaft 758 inserted into the latching groove portion 752 as the second slide block 744 moves to the right and the pivotal member 754 is viewed from above, The left vertical blade 710 also rotates in the counterclockwise direction and is spread in the left direction while rotating in the clockwise direction.

As a result, when the three right blades 710 are rotated in opposite directions, they act in such a manner as to be opened to both sides when viewed from the front side of the air conditioner, thereby allowing the air to be discharged while widening the discharge range.

When the power unit 720 is operated in the clockwise direction as opposed to the squeeze unit, the vertical blade 610 operates in a form in which the vertical blade 610 is closed when seen from the front side. In this case, since the discharged air can be concentrated, the discharge range of the air is narrow, but the discharged air can be sent away.

Accordingly, the air conditioner according to the embodiment of the present invention can arrange the air suction structure, the air-cooling structure and the air discharge structure in series, and provide the three-dimensional beauty feeling when the opening and closing are performed using the blade shape and the blade opening / closing method. In addition, since the filter unit is housed in the side surface of the rear cover, the replacement operation can be simplified. In addition, the present invention provides a mild, luxurious and soft feeling to the user by providing the mood lighting unit under the front frame part.

In addition, since the present invention is installed vertically to the rear cover portion using the installation portion, the installation space can be reduced and the assembling property can be improved. Further, according to the present invention, the blowing fan, the fan guard frame, and the blower housing can be integrated to easily assemble the rear cover unit. In addition, the present invention can provide a structure in which a blowing direction adjusting unit is integrally assembled to the front frame unit, thereby providing a searched structure. Further, in the present invention, the horizontal blade can be easily rotated by switching the straight forward operation to the rotary operation using the operation switching unit.

In addition, the present invention forms the upper blades and the lower blades in opposite directions with respect to the center, and forms a different blowing angle toward the upper and lower sides, so that the horizontal blades can be opened and closed in the form of a wave upon opening and closing. Further, according to the present invention, since the curved protruding portion and the curved groove are repeatedly formed in the horizontal blades, the air flow can be smooth. In addition, the present invention can control the first horizontal blade group disposed on the upper side and the second horizontal blade group disposed on the lower side independently of each other in order to control the air discharge amount.

In addition, in the present invention, since a pair of slide blocks are arranged vertically with respect to one power unit and are moved in the opposite direction, the left and right vertical blades can be reversely operated to open or close the discharge air.
