摘要： A cross-flow fan, and blades of a cross-flow fan are provided. The cross-flow fan includes a rotary shaft; a plurality of blades that extends in a direction parallel to the rotary shaft and having a positive pressure surface and a negative pressure surface; and a connector that connects the rotary shaft and the plurality of blades. At least one protrusion that protrudes in a thickness direction and extends in a longitudinal direction of the plurality of blades is formed on the plurality of blades, and by means of the at least one protrusion formed on a blade surface, a flow separation phenomenon caused by friction with the blade surface is suppressed, thereby reducing noise generated by the cross-flow fan.

摘要： 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.
