<p>PURPOSE:To make it possible to obtain an appropriate air volume selectively from an air purifier by interpreting the movement and presence of a man as well as his activity value, based on a signal from an infrared sensor, and enabling the air volume of the air purifier to be adjustable in a control circuit. CONSTITUTION:A control circuit 4 consisting of a microcomputer 3 interpretes the movement, presence and activity value of a man, based on a signal from an infrared sensor 2, and enables the air volume of an air purifier 5 to be adjustable in accordance with the movement, presence and activity value of a man. Subsequently, it is possible to select between the air volumes of the air purifier appropriately and remove dust rapidly and efficiently.</p> |
