Abstract
A high-performance labyrinth type air treatment apparatus includes a positively (negatively) charged dust collector mounted in an air passage inside a shell, the positively (negatively) charged dust collector having positively (negatively) charged dust collecting panels arranged in such a manner that a labyrinth-like detoured air path is defined through the positively (negatively) charged dust collector, an air ionization control means having discharge/emitting terminals arranged in the labyrinth-like detoured air path, and an electric fan for causing flowing of air through the positively (negatively) charged dust collector so that negatively (positively) charged heteroparticles carried in currents of air flowing through the labyrinth-like detoured air path are forced, to strike repeatedly against the positively (negatively) charged dust collecting panels and then effectively adhered to the positively (negatively) charged dust collecting panels, achieving extremely high air purification.
