Abstract: A blower of the present disclosure includes: a lower case having a suction port; an upper case which has a pair of towers that are spaced apart from each other and form a space through which a discharge air flows therebetween; and a blower fan which is disposed inside the lower case and discharges air to the upper case, wherein each of the pair of towers has a discharge port that is elongated in an up-down direction and disposed closer to a rear end of the tower than a front end, and has an air guide, which is disposed therein, that guides the air discharged by the blower fan to the discharge port, wherein the air guide is convex upward, has one end disposed near a middle between the front end and the rear end of the tower, and has the other end disposed near a middle of a vertical height of the discharge port, wherein the other end is disposed higher than the one end, so that the direction of air flow discharged from the fan can be smoothly switched to the discharge port side by only a single air guide, thereby minimizing the flow resistance inside the blower and greatly improving the economic efficiency and manufacturability of the blower.

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.
