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.

Claims

exact text as granted — not AI-modified
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; and   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,   wherein the first tower includes:   a first boundary surface facing the blowing space and in which the first slit is disposed; and   a first outer surface being opposite to the first boundary surface about an inner space of the first tower, being convex in a direction opposite to the first boundary surface, and being more curved than the first boundary surface,   wherein the second tower includes:   a second boundary surface facing the blowing space and in which the second slit is disposed; and   a second outer surface being opposite to the second boundary surface about an inner space of the second tower, being convex in a direction opposite to the second boundary surface, and being more curved than the second boundary surface, and   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.   
     
     
         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. 
 
     
     
         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 closer to a front end of the first boundary surface than the rear end of the first boundary surface, and 
 wherein the second slot is disposed closer to a front end of the second boundary surface than the rear end of the second boundary surface. 
 
     
     
         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 a shortest distance point at which a distance between the first boundary surface and the second boundary surface is shortest is disposed at a central position between the first and second slits and the first and second dampers.   
     
     
         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 a shortest distance point at which a distance between the first boundary surface and the second boundary surface is shortest.   
     
     
         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 from a shortest distance point at which a distance between the first boundary surface and the second boundary surface is shortest.   
     
     
         11 . The blower of  claim 1 ,
 wherein a front end of the first tower is formed by the contacting of a front end of the first outer surface and a 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 a rear end of the first outer surface and a rear end of the first boundary surface at an acute angle,   wherein a front end of the second tower is formed by the contacting of a front end of the second outer surface and a 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 a rear end of the second outer surface and a rear end of the second boundary surface at an acute angle.   
     
     
         12 . The blower of  claim 1 ,
 wherein a longest distance point at which a distance between the first boundary surface and the first outer surface is longest and a longest distance point at which a distance between the second boundary surface and the second outer surface is longest are collinear with a shortest distance point at which a distance between the first boundary surface and the second boundary surface is shortest.   
     
     
         13 . The blower of  claim 1 ,
 wherein the first and second boundary surfaces are smooth curved surfaces.   
     
     
         14 . 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 a shortest distance point at which a distance between the first boundary surface and the second boundary surface is shortest.
