Abstract: A blower may include a first case and a second case provided above the first case and having a first tower and a second tower that have a passage therebetween. A display assembly is received in the second case at a position that does not interfere with air flowing in the passage. An inner surface of the second tower and an outer surface of a diffuser define a space in which the display assembly is received.

Abstract: A turbo fan includes a hub for coupling a rotating shaft of a motor, a shroud, and a plurality of blades. Each blade includes an inner insertion portion disposed between the hub and the shroud, and an outer extension portion extending from the inner insertion portion and protruding beyond an outer circumference of the hub. Each blade has a positive pressure surface that includes a front surface facing toward a rotational direction and has a convex shape, and a negative pressure surface that includes a rear surface facing toward an opposite direction to the rotational direction and has a concave shape. Each blade further includes a first flow guide protrusion protruding from the positive pressure surface and arranged at an outer end of the outer extension portion, and extends from one side to the other side of the outer end of the outer extension portion in an axial direction.

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 blower may include a body or case having a suction hole through which air passes, a fan provided inside the body and causing a flow of air, and a filter provided inside the body. The filter may be positioned upstream of the fan and extend in a longitudinal direction of the body. A longitudinal axis of the filter may be shifted or displaced with respect to a longitudinal axis of the body.

Abstract: A blowing device is provided. The blowing device includes a first blowing unit that suctions air from above and discharges the air downward, and a second blowing unit disposed below the first blowing portion so as to suction air from below and to discharge the air upward. The blowing device is advantageous in that no matter what position the user is in, wind may be easily discharged to the user.
