<p>PURPOSE:To clean the air in a living space while lowering blowing noise by arranging a dust collector equipped with a dust collecting element and a fan in the internal space of a ceiling provided with an air suction port and a ventilation port and using the internal space of the ceiling as a blowoff chamber. CONSTITUTION:A dust collector 1 having a dust collecting element 12 such as an ionizer and a fan 13 built therein is arranged in the internal space 31 of a ceiling 3. The room air sucked from the suction port 32 provided to the ceiling 3 by the operation of the fan 13 is supplied to the dust collecting element 12 of the dust collector 1 through a duct 4 to adsorb and remove the dust in the sucked air. The cleaned air is blown off to the internal space 31 being a blowoff chamber of the ceiling 3 from the fan 13 through a blowoff port 15 and blown out to a room from a ventilation port 33 along the inner wall surface 22 of the room. By this method, the air in a living space can uniformly cleaned without generating dust collecting irregularity and noise can be reduced by utilizing the internal space of the ceiling.</p> |
