Air cleaner

An air cleaner, comprising:

• an air cleaning module including a fan;
• a circulator disposed at an upper side of the air cleaning module, the circulator being configured to adjust a direction of air that passes through the fan, the circulator including:
• an introduction grill into which air passing through the fan is introduced;
• a fan housing provided above the introduction grill;
• and
• a circulation fan provided within a space defined by the introduction grill and the fan housing;
• an air guide defining an air flow path spaced apart in a radial direction with respect to an axis of the fan to guide the air discharged in the radial direction from the fan upward;
• and
• a discharge guide provided on an upper side of the air guide and discharging air passing through the air guide in an upward direction, the discharge guide including:
• a discharge inner wall including an inner circumferential surface having a cylindrical shape;
• a discharge outer wall that surrounds the discharge inner wall;
• a discharge flow path defined between an inner circumferential surface of the discharge outer wall and an outer circumferential surface of the discharge inner wall and passing air flowing upward by the air flow path;
• and
• a discharge grill disposed in the discharge flow path, the discharge grill being extended from the outer circumferential surface of the discharge inner wall to the inner circumferential surface of the discharge outer wall so as to discharge the air of the discharge flow path in the upward direction,
• wherein the discharge grill has a concave shape in a downward direction, and
• wherein the introduction grill has a concave shape in the downward direction to be received in a concave space defined by the discharge grill at a position corresponding to an upward direction of the discharge grill, wherein the air guide further includes:
• a cylindrical outer wall forming an outer circumferential surface of the air guide;
• a cylindrical inner wall positioned at an inside of the cylindrical outer wall and forming an inner circumferential surface of the air guide;
• and
• a guide rib disposed in the air flow path, the guide rib being configured to extend longitudinally and guide the air discharged from the fan to flow upward, wherein the air flow path is defined between an inner circumferential surface of the cylindrical outer wall and an outer circumferential surface of the cylindrical inner wall.
