1. A spot air-conditioner for drawing in room air and generating conditioned air;
- a blow-off duct rotatably mounted on said air-conditioner for blowing off said conditioned air;
duct drive means for rotating said blow-off duct relative to said air-conditioner in order to change the wind direction of said duct;
means for detecting a body of a person to be cooled in an area which is cooled by said conditioned air; and
wind direction control means, responsive to a human body detected signal outputted from said human body detection means, for controlling said duct drive means to direct said blow-off duct toward the person to be cooled;
said human body detection means including a human body detection device which detects the presence of a person to be air-conditioned in a plane detection region against a background, said human body detection means includinga pair of radiation means for alternately radiating infrared rays, each having a fixed radiation directional angles in said detection region and disposed at a certain opening angle so that said radiation directional angles do not overlap each other;
single radiation receiving means interposed between the radiation means in said detection region for receiving reflection of the infrared rays radiated from said radiation means, said radiation receiving means having a fixed radiation receiving directional angle which partially overlaps with the radiation directional angles of each radiation; and
human body detection and determination means responsive to the output from said radiation receiving means for outputting a human body detected signal when the amounts of reflection of infrared rays radiated from each radiation means both exceed a set value.

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.

3. A spot air-conditioner comprising:
-
an air-conditioner (12) for sucking room air and generating conditioned air; air-conditioning control means (8) for controlling the air-conditioning operation of said air-conditioner (12); a blow-off duct (16) rotatably mounted on said air-conditioner (12) for blowing off said conditioned air; duct drive means (2) for rotating said blow-off duct (16) against said air-conditioner (12) in order to change the wind direction; human body detection means (72) for outputting a human body detected signal when detecting a person to be air-conditioned, and for outputting a human body undetected signal when the person to be air-conditioned cannot be found in an air-conditioning area which is air-conditioned by said conditioned air, as well as for outputting a movement signal when identifying any movement of the person to be air-conditioned; and wind direction control means (75a), responsive to said human body detected signal and said movement signal outputted from said human body detection means (72), for controlling said duct drive means (2) to direct said blow-off duct (16) toward the person to be air-conditioned in accordance with the movement thereof. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
