Abstract

A blower is provided that may include a fan that creates airflow; a lower body forming a lower space therein in which the fan may be disposed, and having at least one suction hole through which air passes; a first upper body positioned above the lower body, and forming a first inner space that communicates with the lower space of the lower body; a second upper body positioned above the lower body, and forming a second inner space that communicates with the lower space of the lower body, the second upper body being spaced apart from the first upper body; and a space formed between the first upper body and the second upper body, and opened in a frontward-rearward direction. The first upper body may include a first slit formed through the first upper body such that air in the first inner space may be discharged into the space, and the second upper body may include a second slit formed through the second upper body such that air in the second inner space may be discharged into the space.

First claim

What is claimed is:

1 . A blower comprising:
a lower body including a suction hole; a first tower disposed above the lower body, and including a first slit discharging air; a second tower disposed above the lower body, spaced apart from the first tower in lateral direction, and including a second slit discharging air; a blowing space formed between the first tower and the second tower, and the air discharged from the first slit and the second slit flows, and wherein the first tower includes a first boundary surface facing the blowing space and in which the first slit is disposed, wherein the second tower includes a second boundary surface facing the blowing space and in which the second slit is disposed, wherein the first boundary surface and the second boundary surface are formed convexly toward each other, and a shortest distance point where a distance between the first boundary surface and the second boundary surface is shortest is formed at a central part in front-rear direction, wherein each of the first and second slits is disposed near a rear end of the first and second boundary surfaces, and the first and second slits are facing each other, and wherein the first and second slits are spaced backward from the shortest distance point.

2 . The blower of claim 1 further comprising:
a first damper assembly disposed in the first tower and including a first damper protruding to the blowing space; and
a second damper assembly disposed in the second tower and including a second damper protruding to the blowing space,
wherein the first damper is disposed between the shortest distance point and a front end of the first boundary surface, and
wherein the second damper is disposed between the shortest distance point and a front end of the second boundary surface.

3 . The blower of claim 2 further comprising:
a first slot formed at the first boundary surface, and wherein the first damper passes through the first slot; and
a second slot formed at the second boundary surface, and wherein the second damper passes through the second slot,
wherein the first slot is disposed between the front end of the first boundary surface and the shortest distance point, and
wherein the second slot is disposed between the front end of the second boundary surface and the shortest distance point.

4 . The blower of claim 3 ,
wherein the first slot is parallel to the front end of the first boundary surface, and the second slot is parallel to the front end of the second boundary surface.

5 . The blower of claim 3 ,
wherein the front end of the first boundary surface is inclined about a vertical direction, and the first slot is inclined more than the front end of the first boundary surface about the vertical direction, and wherein the front end of the second boundary surface is inclined about a vertical direction, and the second slot is inclined more than the front end of the second boundary surface about the vertical direction.

6 . The blower of claim 3 ,
wherein a distance between the first and second slits is shorter than a distance between the first and second slots.

7 . The blower of claim 2 ,
wherein the shortest distance point is disposed in a center between the first and second slits and the first and second damper.

8 . The blower of claim 2 ,
wherein a distance that the first and second dampers are spaced apart from the front ends of the first and second boundary surfaces is shorter than a distance that the first and second dampers are spaced apart from the shortest distance point.

9 . The blower of claim 2 ,
wherein an angle that the rear end of the first boundary surface and the rear end of the second boundary surface is widened outward based on a center line passing through the blowing space in front-rear direction is narrower than an angle that the front end of the first boundary surface and the front end of the second boundary surface is widened outward based on the center line passing through the blowing space in front-rear direction.

10 . The blower of claim 1 ,
wherein a distance that the first and second slits are spaced apart from the rear ends of the first and second boundary surfaces is shorter than a distance that the first and second slits are spaced apart the shortest distance point.

11 . The blower of claim 1 ,
wherein the first tower includes a first outer surface being opposite to the first boundary surface about an inner space of the first tower, and being convex in a direction opposite to the first boundary surface, wherein the second tower includes a second outer surface that is opposite to the second boundary surface about an inner space of the second tower, and that is convex in a direction opposite to the second boundary surface, wherein a front end of the first tower is formed by a contacting of a front end of the first outer surface and a front end of the first boundary surface, wherein a rear end of the first tower is formed by a contacting of the rear end of the first outer surface and the rear end of the first boundary surface, wherein a front end of the second tower is formed by a contacting of a front end of the second outer surface and a front end of the second boundary surface, and wherein a rear end of the second tower is formed by a contacting of the rear end of the second outer surface and the rear end of the second boundary surface.

12 . The blower of claim 11 , wherein the first and second outer surfaces are more curved than the first and second boundary surfaces.

13 . The blower of claim 11 ,
wherein the front end of the first tower is formed by the contacting of the front end of the first outer surface and the front end of the first boundary surface at an acute angle, wherein the rear end of the first tower is formed by the contacting of the rear end of the first outer surface and the rear end of the first boundary surface at an acute angle, wherein the front end of the second tower is formed by the contacting of the front end of the second outer surface and the front end of the second boundary surface at an acute angle, and wherein the rear end of the second tower is formed by the contacting of the rear end of the second outer surface and the rear end of the second boundary surface at an acute angle.

14 . The blower of claim 11 ,
Wherein a longest distance point where a distance between the first boundary surface and the first outer surface is longest and a longest distance point where a distance between the second boundary surface and the second outer surface is longest are collinear with the shortest distance point of the first and second boundary surfaces.

15 . The blower of claim 1 ,
wherein the first and second boundary surfaces are smooth curved surfaces.

16 . The blower of claim 1 ,
wherein an extension line of an opening direction of the first slit and an extension line of an opening direction of the second slit intersect at the shortest distance point.
