Abstract
A blow-off duct is rotatably mounted on an air-conditioner. A human body detection device is provided at the blow-off duct in order to detect the presence of a person to be air-conditioned and then to identify the moving direction thereof. Comfortable localized air-conditioning can be realized since a wind direction control device controls a duct drive device of the blow-off duct in response to a human body detected signal and movement signal outputted by the human body detection device, and thus rotating the blow-off duct in accordance with the movement of the person to be air-conditioned.
