The gas detection section 5 may be disposed on the suction side of a blower installed in the main body 7, so that air that does not pass through the filter flows around the gas detection section 5.

The human body sensor section 6 includes an upper case 11, a lower case 12, a lens body 14, and a sensor substrate 15, as shown in a side sectional view in FIG. 5, an internal plan view in FIG. There is. Cutouts 16.17 are formed in the front walls of the upper case 11 and the lower case 12, and around the cutouts 16.17, there is a groove-shaped, lens-shaped support part 1 that fits and supports the lens body 14.
8.19 is formed, and the lens body 14 is fitted into the support part 18.19 and held between the upper case 11 and the lower case 12, and the notch part 16.17 is closed.

The sensor board 15 is held between the upper case 11 and the lower case 12 by being supported by groove-like or notch-like support portions 20.21 formed in the upper case 11 and the lower case 12. A pyroelectric infrared sensor 22 that utilizes the pyroelectric effect of LiTa0i single crystal to detect a human body is mounted approximately in the center of the sensor substrate 15. The infrared sensor 22 is arranged at the focal point of the lens body 14.

The lens body 14 is made of a polyethylene synthetic resin plate that is transparent to the human body's infrared wavelength (9 to 10 μm).With this configuration, a large number of arcuate grooves are formed to form a single plate-shaped lens. Then, arrange multiple lenses (6 lenses) horizontally in several rows (
2 rows) of plate-shaped lens bodies 14 are formed. The lens body 14 is curved horizontally, vertically, and upwardly so that the focal point of each lens is made to coincide with each other. By combining the single lenses, a light receiving area and a prohibited area are formed for the infrared sensor 22. The light-receiving area is an area where infrared rays corresponding to a person's body temperature are transparent, and the prohibited area is an area through which only infrared rays corresponding to the indoor temperature are transparent, and when a person passes through the light-receiving area, the infrared sensor 22 There is an output.
