• wherein the air circulator comprises:
• a housing having a first inlet and a first outlet formed thereof, and including an outer wall;
• 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,
• wherein an outer wall of the housing comprises:
• a first outer wall extending in a front-rear direction, the first outlet being formed on a front portion thereof;
• and
• a second outer wall having the first inlet formed in a rear portion thereof, and extending from an edge of the first inlet towards the first outer wall to be enlarged in a radially outward direction, 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.
