Abstract

An air management device may include three independently operated primary impellers 131, 131′, 131″, and drawn-in air is discharged through discharge ports 15′-1, 15′-2, 15′-3 provided in the front plate 15 of the housing 10. Louvers 141, 142, 143 installed downstream of the air flow and discharge ports 15′-1, 15′-2, 15′-3 may be independently opened or closed to provide discharge of the air to the surrounding environment. Further, at least one retractable or pop-up fan may be provided. The air management allows customization of air flow. The housing 10 of the furniture-type air management device may be installed on the floor of the livable space and may have a hexahedron shape that extends from side to side. A bottom inlet 11′ may be formed on the bottom plate 11 of the housing 10 facing the floor of the living space above a predetermined distance. The replaceable filter 300 may be installed to filter the air sucked through the bottom inlet 11′, and may be drawn in and out of the housing 10. A plurality of passage openings 302 may be formed in a filter frame 301, and filters 320, 330, and 340 are stacked over the passage openings 302.

First claim

What is claimed is:

1. An air management device, comprising:
a housing defining a space therein and having at least one air inlet provided at the housing and at least one discharge port provided at a front of the housing;
at least one primary impeller provided inside the housing to create an air flow to flow through the space;
a heat exchanger provided in the housing and configured to exchange heat air of the air flow; and
at least one discharge unit provided inside the housing and having a pop-up duct configured to retract into the housing or to protrude upward through an opening provided on an upper surface of the housing to discharge one of air and heat exchange air from the air flow caused by the at least one primary impeller,
wherein the pop-up duct is accommodated in a vertical duct inside the housing, the vertical duct configured to receive the air flow formed by the at least one primary impeller, and the pop-up duct being rotatably supported by a lift platform,
wherein a first lift gear is provided vertically on the vertical duct and a lift motor having a second lift gear is provided on the lift platform, wherein when the lift motor is driven, the second lift gear rotates to raise the lift platform along the first lift gear such that the pop-up duct rises above the upper surface of the housing.

2. The air management device of claim 1 , wherein the pop-up duct includes discharge vents formed on an outer surface of the pop-up duct, an area occupied by the discharge vents is smaller than 180 degrees with respect to a center of the pop-up duct.

3. The air management device of claim 1 , wherein a rotary motor having a first rotary gear is provided on the lift platform, and the pop-up duct is support by a support base having a second rotary gear, wherein when the rotary motor is driven, the first rotary gear rotates to be guided along a rack of the second rotary gear such that the pop-up duct rotates about a center of the pop-up duct.

4. The air management device according to claim 3 , wherein a directional blade is installed inside the pop-up duct to direct an angle of air discharged through discharge vents.

5. The air management device of claim 4 , further comprising a secondary impeller for pressurizing the air discharged through the pop-up duct.

6. The air management device of claim 5 , wherein the secondary impeller is installed in a passage formed in the lift platform.

7. The air management device of claim 1 , wherein the housing includes a primary impeller guide provided between the heat exchanger and the at least one discharge port, the primary impeller guide having at least one opening to house the at least one primary impeller.
