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 that may include a lower base, a lower housing, a plurality of legs, a leg wall, and an input assembly. The lower base may be supported by an installation surface. The lower housing may be spaced apart upwardly from the lower base and form a suction gap by being spaced apart from the lower base. The plurality of legs may be disposed on at least one of the lower base or a lower housing. The plurality of legs may support the lower housing. The leg wall may connect two adjacent legs to each other. The input assembly may be disposed at the lower housing. The input assembly may protrude toward the suction gap. The input assembly may receive a wireless signal. The plurality of legs may include a first leg and a second leg adjacent to each other. The input assembly may be disposed outside of the leg wall. As an input assembly receiving a voice signal is exposed to the outside, a user's voice may be effectively recognized. Further, as the leg wall is disposed between the input assembly and the lower housing inlet, it is possible to suppress propagation of operating noise generated by a blowing unit to the input assembly.

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.
