For example, in winter, purified air is discharged directly to a person, thereby preventing cold caused by the discharged air.

Meanwhile, as shown in FIGS. 3 and 9, when the operation of the separate air conditioner is stopped, the compressor 126 and the outdoor blower 128 of the outdoor unit 120 are stopped, and the front panel rotating motor is stopped. The 68 and the louver rotating motor 76 are driven in a closed mode, and the indoor blower 90 of the indoor unit 51 is also stopped from driving.

That is, when the front panel rotational motor 68 is driven in the closed mode, the pinion 67 is rotated backward to reverse the rack 69, the front panel 60 is the first link 65 Is rotated forward with respect to the front air inlet 55 of the front frame 54 is blocked.

When the louver rotational motor 76 is driven in the closed mode, the louver 75 seals the suction hole 71a of the filter case 71.

The air conditioning mode, the air cleaning mode, and the stop operating as described above are selectively operated and controlled by the control unit 111 of the control box 110 according to the condition of the indoor air.
