Abstract

An air conditioner including a casing, a heat exchanger, a cross-flow fan, a rear guide, and a stabilizer installed within the casing in the vicinity of an air outlet so as to be close to the cross-flow fan, wherein the stabilizer has a rib portion.

1 . An air conditioner comprising: 
 an indoor unit wherein said indoor unit comprises:    a casing formed with an air inlet and an air outlet,    a heat exchanger provided within the casing,    a cross-flow fan installed inside the heat exchanger,    a rear guide for guiding air drawn in by the cross-flow fan, and    a stabilizer installed within the casing in the vicinity of the air outlet so as to be close to the cross-flow fan,    wherein the stabilizer has a rib portion.    
   
   
       2 . The air conditioner according to  claim 1 , wherein the rib portion of the stabilizer has a curved triangular cross-sectional shape such that one side of the rib portion facing the cross-flow fan is gently recessed.  
   
   
       3 . The air conditioner according to  claim 1 , wherein the rib portion of the stabilizer has a curved triangular cross-sectional shape such that one side of the rib portion facing the cross-flow fan is gently expanded.  
   
   
       4 . The air conditioner according to  claim 1 , wherein the rib portion of the stabilizer has a triangular cross-sectional shape being flat at one side of the rib portion facing the cross-flow fan and has a height increasing toward the air outlet while being round at a corner of the rib portion arranged toward the air outlet.  
   
   
       5 . The air conditioner according to  claim 1 , wherein the rib portion of the stabilizer comprises convex ribs and concave ribs, which are alternated in a longitudinal direction of the stabilizer.  
   
   
       6 . The air conditioner according to  claim 1 , wherein the rib portion of the stabilizer forms a predetermined angle with a lateral direction of the stabilizer.  
   
   
       7 . The air conditioner according to  claim 6 , wherein the predetermined angle is between 0 and 45 degrees.  
   
   
       8 . An air conditioner comprising: 
 an indoor unit, wherein said indoor unit comprises:    a casing formed with an air inlet and an air outlet,    a heat exchanger provided within the casing,    a cross-flow fan installed inside the heat exchanger,    a rear guide for guiding air drawn in by the cross-flow fan, and    a stabilizer installed within the casing in the vicinity of the air outlet so as to be close to the cross-flow fan,    wherein the stabilizer has a rib portion having a convex and concave contour, the rib portion forming a predetermined angle in a lateral direction of the stabilizer.    
   
   
       9 . The air conditioner according to  claim 8 , wherein the rib portion of the stabilizer has a curved triangular cross-sectional shape such that one side of the rib portion facing the cross-flow fan is gently recessed.  
   
   
       10 . The air conditioner according to  claim 8 , wherein the rib portion of the stabilizer has a curved triangular cross-sectional shape such that one side of the rib portion facing the cross-flow fan is gently expanded.  
   
   
       11 . The air conditioner according to  claim 8 , wherein the rib portion of the stabilizer has a triangular cross-sectional shape being flat at one side of the rib portion facing the cross-flow fan and having a height increasing toward the air outlet while being round at a corner of the rib portion arranged toward the air outlet.  
   
   
       12 . The air conditioner according to  claim 8 , wherein the predetermined angle is between 0 and 45 degrees.
