Claims (1)

[Scope of utility model registration request] The air conditioner human detection device includes a sensor 3 that is installed in the air conditioner main body 20 and is sensitive to infrared rays from the human body, and the light condensing means 5 disposed close to the sensor 3 has the above-mentioned When the air conditioner main body 20 is installed at a reference position on a wall surface, polarizers 1 to 8 converge light from a detection area S in the room onto the sensor 3, and adjacent virtual polarizers outside the detection area S. Preliminary polarizers 9 and 10 are provided to condense the light from the region At the reference position, the range of incident light passing through the polarizing units 1 to 8 is set, while the air conditioner main body 2
0 is different from the reference position, a switching means 25 is provided for switching from the detection area S to the range of incident light passing through the polarizing sections 1 to 8 and the preliminary polarizing sections 9 and 10. Person detection device for air conditioners.
