Abstract: An air cleaner includes a blower, a circulator disposed over the blower, and a mover coupled to the circulator and configured to change an arrangement of the circulator. The circulator includes a lower cover, an upper cover disposed over the lower cover, a blower fan rotatably disposed between the lower cover and the upper cover, a motor disposed on an upper side of the lower cover and rotating the blower fan, an inner cover disposed over the lower cover and receiving a lower portion of the blower fan, and a bell mouth protruding upwardly from an inner circumferential end of an inner plate of the inner cover and spaced apart outwardly from a circumferential surface of a suction guider of the blower fan, so as to guide air, drawn in through an inlet of the lower cover, toward an inlet of the blower fan.

Abstract: A centrifugal fan includes a main plate rotating about an axis of rotation, a shroud having an inlet port for introduction of air, and a plurality of blades circumferentially arranged between the main plate and the shroud so as to form a flow of air by accelerating air introduced through the inlet port. Each blade has a pressure surface formed such that a portion thereof near to the shroud is convex and a portion thereof near to the main plate is concave. The shroud has an inside surface formed as a curved surface, and the curved surface has a diffusion section extending radially. The main plate has a curved surface extending radially, and a curved surface of the shroud in the diffusion section at least partially overlaps with the curved surface formed in the main plate when viewed in a direction of the axis of rotation.
