Abstract

PURPOSE: To detect the presence of a man in order to comfortably feed air, by binarizing the output signal of a means detecting the infrared rays emitted from the man, who is in the range influenced by the fan, and by switching a fan driving motor in the state of ON or OFF corresponding to the presence or absence of the man.
CONSTITUTION: Infrared rays having a wavelength of about 10μm emitted from a human's body is taken in an optical system 82. Then, the infrared rays is incident to a detecting element 84, positioned at the three dimensional focus of the optical system 82, through a filter 83 omitting an external scattered light, where it is converted into an electrical signal. A detecting signal is binarized into ON and OFF, since the detecting signal contains the infrared rays emitted from the human's body with a temperature of about 37°C, and the infrared rays emitted from a surrounding substance, when the detecting signal is amplified by an amplifier 85, the motor is turned ON when the variation of increase/decrease of the detecting signal exceeds a given range.
