Abstract: An air conditioner includes a housing that defines an air inlet and an air outlet, a heat exchanger, a blowing fan inside the housing, a lower guide configured to guide, toward the air outlet, air discharged to a rear side of the blowing fan and a lower side of the blowing fan, and an upper guide that is disposed vertically above the lower guide and that defines a discharge flow path with the lower guide. The discharge flow path extends from the blowing fan to the air outlet, and a cross sectional area of the discharge flow path increases toward the air outlet. The upper guide defines a curved surface that is disposed at a downstream end of the upper guide adjacent to the air outlet and that is convex toward the air outlet.

Abstract: The present invention relates to a blower, the blower according to an embodiment of the present invention comprising: a lower case having a suction hole formed therein through which air is introduced; an upper case arranged on the upper side of the lower case and having a discharge hole formed therein through which air is discharged; and a fan arranged in the lower case and including a plurality of blades. Each of the plurality of blades includes a plurality of airfoils respectively extending along different camber lines from one another, and a leading edge of connecting the leading ends of the plurality of airfoils. Entrance angles formed by the respective camber lines of the plurality of airfoils and the rotation directions of the blades are different from one another. Thus, due to the curved shape of the leading edge and the design of a recessed notch, a flow separating from the leading edge is reduced, and thus, there is an advantage in that air volume performance is improved.
