Abstract
An object detector for an air conditioner has a signal detection input unit in which a light block is provided between a pair of Fresnel lenses spaced in parallel by a predetermined distance on a printed circuit board, thereby defining substantially three detection areas. The signal detection input unit detects the number, locations and movement distance of persons present indoor from a received signal, and outputs a signal representative of the information. Then, a command for the operation of an air conditioner is issued according to the information signal, thereby enabling the optimum operation of the air conditioner under circumstances.
Claims12
An object detector for an air conditioner comprising:
- signal detection input means having a pair of Fresnel lenses spaced in parallel by a predetermined distance on a printed circuit board, and light blocking means between said Fresnel lenses, so that substantially three signal detection areas are defined;
- signal processing circuit having superconductive devices, amplifiers, and window comparators sequentially connected to said respective Fresnel lenses, and a logic calculator connected to said window comparators, to classify a signal detected through said signal detection input means into a signal waveform for each of said signal detection areas;
- and
- a microcomputer for receiving said signal waveform from said signal processing circuit and outputting a command signal for controlling the operation of said air conditioner.
