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: An air circulator includes a housing having a first inlet and a first outlet, an oblique-flow fan disposed in the housing, and a motor rotating the oblique-flow fan. An outer wall of the housing includes a first outer wall extending in a front-rear direction and a second outer wall having the first inlet and extending from an edge of the first inlet towards the first outer wall to be enlarged in a radially outward direction. An outer surface of the second outer wall comprises a first surface that extends towards the first outer wall to be rounded outwards, and forms a surface continuous with an outer surface of the first outer wall, thus guiding air flowing along an outside of the first inlet so that the air flows forwards along the outer surface of the first outer wall.
