BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of switching a discharge direction of air according to a cooling / heating operation or an installation height such that a plurality of combined air inlets and outlets for indoor air are sucked or discharged are formed.

In general, an air conditioner uses a refrigeration cycle of refrigerant consisting of a compressor, a four-way valve, an outdoor heat exchanger (condenser or evaporator), an expansion device, and an indoor heat exchanger (evaporator or condenser) to create a more comfortable indoor environment for the user. By cooling or heating, it is largely divided into a separate type and an integrated type.

The separate type and the integrated type are functionally the same, but the separate type installs the cooling / heating unit, the indoor fan and the indoor fan motor in the indoor unit, and the heat dissipation / cooling unit, the compression unit, the outdoor fan and the outdoor fan motor in the outdoor unit. The indoor and outdoor units separated from each other are connected by a refrigerant pipe, and the integrated type is a unit installed by directly drilling a hole in a wall of a house or hanging a device on a window by integrating a function of cooling heat dissipation.

The rack 27A ″ is formed long in the front lower shutter 27 ″ vertically.

The front lower shutter motor 28 ″ is mounted with a pinion 28B ″ which meshes with the rack 27A ″ on the rotation shaft 28A ″.

The front lower shutter motor 28 ″ is shown in FIG. 10 during the cooling operation. The lower auxiliary air intake 26 ″ is driven in the open mode in which the lower auxiliary air intake 26 ″ is opened by the front lower shutter 27 ″ so that indoor air A is sucked through the lower auxiliary air intake 26 ″, and the heating operation is performed. As shown in FIG. 11, the lower auxiliary air intake 26 ″ is provided in the front lower shutter 27 ″ such that indoor air B is not sucked or discharged into the lower auxiliary air intake 26 ″. It is driven in a sealed mode that is sealed by.

The air conditioner of the present invention configured as described above can discharge the indoor air in various directions of the air conditioner, and there is an advantage that the discharge direction of the air can be switched according to the cooling / heating operation or the installation height. Minimization of the flow bending, the blowing efficiency is high, there is an advantage that faster cooling / heating is possible.

In addition, the air conditioner of the present invention has an advantage that the secondary air inlet is formed in at least one of the main chassis and the front panel, it is possible to intake / heat exchange the air in the room more quickly.

In addition, the air conditioner of the present invention has an advantage that the secondary air discharge port is formed in the main chassis, not only can discharge the heat-exchanged air in various directions, but also can quickly supply the cold / warm air to the room.

In addition, the air conditioner of the present invention is provided with a secondary air inlet to the main chassis, it is possible to suck the air in the room in at least two directions or to discharge in at least two directions, it is possible to discharge the cold air / warm air in more various directions This has the advantage of being able to discharge more quickly.
