Abstract: The present application proposes an air cleaner including a blower configured to inhale air from an outside, filter the inhaled air, and discharge the filtered air; a flow adjusting device disposed above the blower, wherein the flow adjusting device is configured to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air and discharge the air therefrom to the outside in a adjusted direction; and a guide member having one end passing through an upper surface of the blower and received in the blower, and the other end connected to the flow adjusting device. The guide member is configured to retract into an interior of the blower or extend from the upper surface of the blower to induce position change of the flow adjusting device. The angle defined between the upper surface of the flow adjusting device and the upper surface of the blower increases or decreases primarily based on an extent to which the guide member extends from the blower.

Abstract: Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. The guide member may include a plurality of gears arranged inside the guide member to be rotatable, some of the plurality of gears may be connected to each other to be rotatable in engagement with each other, and the flow adjusting device may change the discharge direction of the air by rotations of the plurality of gears of the guide member.

Abstract: Disclosed is an air cleaner, more specifically, an air cleaner including a blower that inhales air from the outside, and filters the inhaled air, and discharges the filtered air, a flow adjusting device disposed on the blower to inhale the air discharged from the blower, adjust a discharge direction of the inhaled air, and discharge the air, and a guide member disposed below the flow adjusting device to change a state of the flow adjusting device. An angle formed between a top surface of the flow adjusting device and a top surface of the blower may increase or decrease based on operations of the plurality of links, so that the state of the flow adjusting device may be changed from an orientation in which the top surface of the flow adjusting device is horizontal with the top surface of the blower to an orientation in which the top surface of the flow adjusting device is perpendicular to the top surface of the blower.
