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 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.
