Air conditioner

Abstract

An air conditioner is provided. The air conditioner may include a casing in which an inlet, a first outlet positioned at a front thereof, and a second outlet positioned at a lower surface thereof are formed, a fan that creates an air flow from the inlet to the first outlet or the second outlet, and a first vane that opens or closes the second outlet. The first vane closes the second outlet to discharge air through the first outlet, or opens the second outlet to discharge air under the first outlet.

What is claimed is: 
     
         1 . An air conditioner, comprising:
 a casing in which an inlet, a first outlet positioned at a front thereof, and a second outlet positioned at a lower surface thereof are formed;   a fan that creates an air flow from the inlet to the first outlet or the second outlet; and   a first vane that opens or closes the second outlet, wherein the first vane closes the second outlet to discharge air through the first outlet, or opens the second outlet to discharge air below the first outlet.   
     
     
         2 . The air conditioner of  claim 1 , wherein the first vane guides air blown by the fan to the first outlet when positioned in the second outlet. 
     
     
         3 . The air conditioner of  claim 1 , wherein the first outlet is positioned in front of a rotational center of the fan, and wherein the second outlet is positioned between the first outlet and the rotational center of the fan in a frontward-backward direction. 
     
     
         4 . The air conditioner of  claim 1 , further comprising:
 a front guide that partitions the first outlet and the second outlet.   
     
     
         5 . The air conditioner of  claim 4 , wherein an upper surface of the front guide extends in forward and upward directions toward the first outlet is positioned. 
     
     
         6 . The air conditioner of  claim 4 , wherein the front guide comprises:
 an upper guide that forms a surface inclined forward and upward; and   a lower guide that forms a surface inclined forward and downward.   
     
     
         7 . The air conditioner of  claim 6 , wherein a front end of the first vane forms an inclined surface that extends downward as it extends forward, and wherein the front end of the first vane is positioned under the lower guide, when the first vane closes the second outlet. 
     
     
         8 . The air conditioner of  claim 1 , wherein a front vane is positioned in the first outlet. 
     
     
         9 . The air conditioner of  claim 8 , wherein the front vane is inclined forward and upward. 
     
     
         10 . The air conditioner of  claim 1 , further comprising:
 a second vane that guides a flow of air generated by the fan.   
     
     
         11 . The air conditioner of  claim 10 , wherein when the first vane is positioned in the second outlet, the second vane is positioned so that a front end of the second vane faces forward to guide air to the first outlet. 
     
     
         12 . An air conditioner, comprising:
 a casing in which an inlet, a first outlet positioned at a front thereof, and a second outlet positioned at a lower surface thereof are formed;   a fan that creates an air flow from the inlet to the first outlet or the second outlet;   a first vane that opens or closes the second outlet, wherein the first vane closes the second outlet to discharge air through the first outlet, or opens the second outlet to discharge air below the first outlet; and   a guide that partitions the first outlet and the second outlet, an inclined upper surface of the guide extending forward and upward toward the first outlet and an inclined lower surface of the guide extending forward and downward.   
     
     
         13 . The air conditioner of  claim 12 , wherein a front end of the first vane forms an inclined surface that extends downward as it extends forward, and wherein the front end of the first vane is positioned under the inclined lower surface of the guide, when the first vane closes the second outlet. 
     
     
         14 . The air conditioner of  claim 12 , wherein a front vane is positioned in the first outlet. 
     
     
         15 . The air conditioner of  claim 14 , wherein the front vane is inclined forward and upward. 
     
     
         16 . The air conditioner of  claim 1 , further comprising:
 a second vane that guides a flow of air generated by the fan.   
     
     
         17 . The air conditioner of  claim 16 , wherein when the first vane is positioned in the second outlet, the second vane is positioned so that a front end of the second vane faces forward to guide air to the first outlet. 
     
     
         18 . An air conditioner, comprising:
 a casing in which an inlet, a first outlet positioned at a front thereof, and a second outlet positioned at a lower surface thereof are formed;   a fan that creates an air flow from the inlet to the first outlet or the second outlet;   a first vane that opens or closes the second outlet, wherein the first vane closes the second outlet to discharge air through the first outlet, or opens the second outlet to discharge air below the first outlet; and   a second vane positioned adjacent to the first vane, wherein the first vane guides air blown by the fan to the first outlet when positioned in the second outlet, and wherein when the first vane is positioned in the second outlet, the second vane is positioned so that a front end of the second vane faces forward to guide air to the first outlet.   
     
     
         19 . The air conditioner of  claim 18 , wherein the first outlet is positioned in front of a rotational center of the fan, and wherein the second outlet is positioned between the first outlet and the rotational center of the fan in a frontward-backward direction. 
     
     
         20 . The air conditioner of  claim 18 , further comprising:
 a front vane is positioned in the first outlet, wherein the front vane is inclined forward and upward.
