The present invention relates to an air conditioner, and more particularly, to an air conditioner in which an air purifier for purifying air is disposed in front of an air intake hole of an orifice.

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 outdoor unit separated by refrigerant pipes by installing a cooling / heating unit in an indoor unit and a heat radiating / cooling and compression unit in an outdoor unit. It integrates the function of heat dissipation, and installs it by drilling a hole in the wall of the house or hanging the device on the window.

6 to 8, the indoor unit of the conventional split type air conditioner includes a base 101, a cabinet 102 disposed on an upper side of the base 101 and an open front surface thereof, and the cabinet 102. The front panel is coupled to the front surface, and the front air outlet 104a and the upper side air outlets 104b and 104c are formed on the upper sides, respectively, and the air inlets 104d and 104e are formed on the lower sides. 104, a blower 120 disposed below the cabinet 102 and the front panel 104, and a heat exchanger 130 disposed above the blower 120.

The front panel 104 includes a front upper panel 105 having the front air outlet 104a and the side air outlets 104b and 104c, a central lower portion of the front upper panel 105, and the base 101. And a front lower panel 106 disposed between the lower sides of the cabinet 102 to form the air inlets 104d and 104e, and the side end of the front lower panel 106 and the Between the lower part of the cabinet 102, left and right suction grills 107 and 108 for protecting the suction ports 104d and 104e are mounted to be opened and closed.
