The orientation is controlled by variably driving.

As the air conditioning system, a plurality of human body detection air conditioning air outlets and control devices having this configuration are installed in the air conditioning duct 20, and an air conditioner 21 is installed at the end of the air conditioning duct 20.

In the above configuration, the plurality of human body detection sensors 2a to 2n installed so as to surround the conditioned air outlet 1 in the horizontal direction are output because they are mounted in order so that their detection areas do not overlap. Each detected signal can directly indicate the direction of the region where the human body exists. The human body detecting means 3 captures these signals, determines which human body detecting sensor is outputting the signal, and uses the wind direction changing means 5 to output the signal from the conditioned air outlet 1 to the human body detecting sensor. , The conditioned air is automatically supplied to the region where the human body is present.

In the present embodiment, the rotation direction of the air-conditioned air outlet is horizontal and the detection area is circular. However, the installation direction of the air-conditioned air outlet is changed so that the rotation direction is vertical, and The detection area may be developed as a straight line, and no difference occurs in the operation and effect.

(Embodiment 2) As shown in FIGS. 3 and 4, the conditioned air outlet 1 has a variable rotation angle in both the forward and reverse directions to blow conditioned air in an arbitrary horizontal direction.

In order to collectively process the signals from these sensors, a signal from the control device shown in the block diagram of FIG. 4 is received, and the air-conditioning air outlet 1 is rotated by the wind direction changing means 5 in both forward and reverse directions. The orientation is controlled by variably driving.

In the above configuration, as shown in FIG.
In a situation where the human body detection sensor 2a is outputting a detection signal among the plurality of human body detection sensors, the human body detection means having received the signal sends the information to the area determination means 4. As a result, the area discriminating means 4 sends the human body detection sensor 2a to the wind direction changing means 5.
