The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner capable of purifying air sucked through a base.

In general, an air conditioner is used to cool or heat a room or purify the air by using a refrigeration cycle of a refrigerant consisting of a compressor, a condenser, an expansion mechanism, and an evaporator to create a more comfortable indoor environment for a user. .

The separate type and the integrated type are functionally the same, but the separate type connects the indoor unit and the outdoor unit separated by the refrigerant pipes by installing the cooling / heating unit in the indoor unit and the heat radiating / cooling and compression unit in the outdoor unit, and the integrated type by cooling heat dissipation. Integrate the function of the hole in the wall of the house or hang the device on the window is installed directly.

6 to 9, the indoor unit of the conventional split type air conditioner includes a base 1, a cabinet 2 arranged longitudinally on the upper side of the base 1 and having an open front surface; It is coupled to the front surface of the cabinet (2), the front air discharge port (4a) and the upper side of the side air discharge port (4b, 4c) is formed on both sides, the front surface of the air inlet (4d, 4e) formed on both sides And a panel 4, a blower 20 disposed below the cabinet 2 and the front panel 4, and a heat exchanger 30 disposed above the blower 20.                         

On the other hand, the front panel 4 is provided with a vertical drive panel 10 in the front of the front panel 4 so as to open and close the opening and closing the front air discharge port (4a), the vertical drive panel 10 In order to eliminate the step between the front panel 4 and the up and down drive panel 10 at the time of rising, the front and rear drive panel 12 is installed on the front of the front panel 4 to be retracted, and the side air outlet 4b The left and right vanes 14 and 16 are rotatable on both sides of the front panel 4 so as to control the wind direction of the air discharged through the side air discharge ports 4b and 4c and to open and close the 4c. Is mounted.
