Claims

[Scope of utility model registration request]

An infrared sensor that detects radiant energy from the human body, a Fresnel lens for concentrating infrared light installed in front of the infrared sensor, an amplifier that amplifies the output signal from the infrared sensor, and a signal necessary for human body detection. In an air conditioner with a human body detection device that determines the presence or absence of a human body based on whether the output waveform from the filter to be taken out and the amplifier reaches a predetermined determination level, the infrared sensor and the Fresnel lens are oscillated within a predetermined range. and a light shielding means that covers the outer periphery of the optical path from the Fresnel lens to the infrared sensor and blocks light other than light that passes through the Fresnel lens and reaches the infrared sensor. Air conditioner.
