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.

First claim

What is claimed is:

1. A blower, comprising:
a first case including a suction port and accommodating a fan;
a second case including a tower base disposed over the first case, the second case including a first tower and a second tower provided above the tower base with being spaced apart from each other;
a passage provided between the first tower and the second tower;
a first discharge port formed in the first tower and configured to discharge air into the passage;
a second discharge port formed in the second tower and configured to discharge air into the passage;
a diffuser provided inside the tower base to guide air discharged by the fan toward the first and second discharge ports;
a display assembly provided inside the tower base and having a display exposed through a surface of the tower base; and
wherein the diffuser includes:
an inner body;
an outer body surrounding the inner body and spaced apart from the inner body to define an air flow path therebetween; and
a plurality of guide vanes extending between the outer body and the inner body to guide air flow, and
wherein at least a portion of the outer body aligned with the passage in a vertical direction bends inward toward the inner body as to form a receiving space in which the display assembly is received.

2. The blower of claim 1 , wherein the outer body includes:
a first outer body bent inward toward the inner body; and
a second outer body connected to the first outer body, the second outer body being concentric with the inner body to share a center with the inner body,
wherein the first outer body is positioned to be further inward toward a center of the inner body than a circumferential surface of the second outer body in a radial direction of the second outer body.

3. The blower of claim 2 , wherein circumferential ends of the first outer body are located farther from the center of the inner body compared to a center of the first outer body.

4. The blower of claim 2 , wherein the first outer body forms a chord of a circumference of the second outer body.

5. The blower of claim 2 , wherein the first outer body includes:
a first surface supporting a first surface of the display assembly, and facing the tower base; and
a second surface supporting a second surface of the display assembly, and disposed between the tower base and the first surface.

6. The blower of claim 2 , wherein the plurality of guide vanes are provided in an area of the air flow path that is not adjacent to the first outer body.

7. The blower of claim 2 , wherein the display assembly includes:
a flat panel display configured to display visual information; and
a substrate configured to supply power to the flat panel display, wherein at least a part of the substrate is in contact with the first outer body.

8. The blower of claim 1 , wherein:
the display assembly is provided at a first side of the blower, and the first and second discharge ports are provided at a second side of the blower opposite to the first side.

9. The blower of claim 1 , wherein the first tower includes a first inner wall where the first discharge port is formed, the second tower includes a second inner wall where the second discharge port is formed and facing the first inner wall,
wherein an upper surface of the tower base connects lower ends of the first and second inner walls,
wherein the first and second inner walls and the upper surface of the tower base define a boundary of the passage, and
wherein the display assembly disposed below the upper surface of the tower base.

10. The blower of claim 9 , wherein the diffuser is spaced downward from the upper surface of the tower base.

11. The blower of claim 1 , wherein the display assembly is inclined to an inner space of the tower base.
