PURPOSE:To obtain an air purifier easy to use and released from the attachment and detachment work of an air passage member, by providing air purification function and air blowing function effective for the ventilation of a room to one machinery so as to be capable of easily changing over both functions. CONSTITUTION:In order to obtain air purification functions, a movable plate 18A is held at the position at a right angle to a fan axial direction and an outer member 20 is superposed to the whole outer peripheral surface of an inner member 19. A filter 13 is set to the outer member 20 so as to be parallel to the outside opening surface thereof and air sucked through the filter 13 is blown off from an air blow-off port 14. In order to obtain air blowing function, the movable plate 18A is held at the position parallel to the fan axial direction and the outer member 20 is slid to the external direction and the inner peripheral surface of the inside opening part of the outer member 20 is superposed to the outer peripheral surface of the outside opening part of the inner member 19. Air in a room is sucked from an air sucking port 21 and blown off from the part opened by the movable plate 18A. |
