PROBLEM TO BE SOLVED: To provide the controller of an air cleaner which performs proper operation by correcting the output property of a dust sensor to the concentration of dust, and preventing the dispersion of products which occurs, according to the degree of pollution of indoor air. SOLUTION: This is an air cleaner which is equipped with a blow fan 4, a filter for collecting the dust from indoor air, a dust sensor 1 for detecting the concentration of dust in air, and a controller 2 for controlling the number of revolutions of the blow fan 4, according to the detected dust concentration, and a writer 6 which is equipped with an output measuring part 6a for measuring the output at specified dust concentration of the dust sensor 1, a corrector 6b for correcting the output at specified dust concentration to the preset reference value, and a write part 6c for writing this correction data into an IC is prepared, and this air cleaner is provided with a memory 2 to store the correction data, according to the output of the dust sensor 1, and this controller writes the correction data into the memory 2 and performs the operation and stoppage of the air cleaner and the automatic operation control of the number of revolutions of the blow fan, based on the correction value. |
