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: A humidification and air cleaning apparatus is provided, in which a first sweep angle and a second sweep angle are formed at diffuser blades, and an included angle is formed between the first sweep angle and the second sweep angle, such that a phase difference is formed in air passing through the diffuser blades, and thus, air flow noise may be reduced.
