<p>An air conditioner is provided to collect dust in an indoor space by an electric dust collection air-conditioning unit, and to provide optimal indoor environment with little amount of the dust by shaking an up/down or/and left/right wind direction plate. An air conditioner comprises a housing(21), an operation panel(251), a vertical wind direction plate(291), a blowing fan, a blow motor, an indoor heat exchanger(33), an electric dust collection air-conditioning unit(40), a human sensing sensor and a control device. The housing has an air intake hole(27) in an upper part, and an air discharge hole in a lower part. The operation panel is installed so as to open/close a part of the air intake hole. The vertical wind direction plate is installed so as to be rotated in the air discharge hole. The blowing fan takes indoor air in from the air intake hole and discharges indoor air to the air discharge hole. The blow motor drives the blowing fan. The indoor heat exchanger is installed in an intake side of the blowing fan. The electric dust collection air-conditioning unit is installed between the air intake hole and the heat exchanger. The human sensing sensor detects existence of a human being in the indoor. The control device controls to make the vertical wind direction plate to be downward or shaking.</p> |
