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.

Abstract: A air cleaner includes a blowing device and a circulator movably disposed above the blowing device. The circulator includes a housing extending in a front-rear direction, a first inlet being formed in a rear portion of the housing and a first outlet being formed in a front portion of the housing, a circulation fan disposed in the housing to suction air through the first inlet and then discharge the air through the first outlet to a front of the housing, and a motor rotating the circulation fan. The first inlet is disposed above a second outlet of the blowing device inside an imaginary extension surface vertically extending an edge of the second outlet, and has a diameter smaller than a diameter of the second outlet, thus suctioning air discharged from the second outlet and increasing an intake ratio of clean air that undergoes a cleaning operation of the blowing device.
