Air conditioner

Abstract

An air conditioner includes a discharge blade configured to move between a guide position at which a direction of air blown from a blower fan and discharged to an outlet is controlled, and a closing position at which the outlet is closed, wherein the discharge blade includes a plurality of blade holes through which the air is discharged through the discharge blade at the closing position, wherein the discharge blade moves between the guide position and the closing position and controls an air flow from the blower fan to a discharge plate or the outlet. Through this configuration, an air flow discharged to the outside of the housing can be controlled by operation of the discharge blade.

What is claimed is: 
     
         1 . An indoor unit of an air conditioner comprising:
 a housing including a discharge plate having a plurality of holes formed therein, a housing door disposed in front of the discharge plate, and an outlet;   a heat exchanger disposed inside the housing; and   a blower fan configured to blow air heat-exchanged by the heat exchanger toward the outlet and the plurality of holes,   wherein the housing door is configured to move between an open position at which the discharge plate is exposed to an outside, and a closing position at which the discharge plate is blocked by the housing door.   
     
     
         2 . The air conditioner according to  claim 1 , wherein the housing door is configured to be slidable between the open position and the closing position. 
     
     
         3 . The air conditioner according to  claim 1 , wherein
 the housing door includes a first door and a second door disposed below the first door, and   the first door is configured to open and to close a top portion of the discharge plate, and   the second door is configured to open and to close a bottom portion of the discharge plate.   
     
     
         4 . The air conditioner according to  claim 3 , wherein the first door and the second door are configured to operate to be in contact with each other when the housing door is at the closing position. 
     
     
         5 . The air conditioner according to  claim 3 , wherein
 the housing door disposed in front of the outlet, and   the second door is configured to open and to close the outlet.   
     
     
         6 . The air conditioner according to  claim 3 , wherein the first door and the second door are disposed at the closing position when the air conditioner does not operate. 
     
     
         7 . The air conditioner according to  claim 3 , wherein the first door and the second door are disposed at the open position when the air conditioner operates. 
     
     
         8 . The air conditioner according to  claim 1 , further comprising:
 a discharge blade configured to move between a guide position at which a direction of the air blown from the blower fan and discharged to the outlet is controlled, and a closing position at which the outlet is closed and the discharge blade is substantially flush with the discharge plate.   
     
     
         9 . The air conditioner according to  claim 8 , wherein the discharge blade includes a blade body rotatably disposed in the outlet, and a plurality of blade holes formed in the blade body so as to discharge air passing through the discharge blade. 
     
     
         10 . The air conditioner according to  claim 9 , wherein
 the housing includes a side panel having a plurality of holes formed therein, and   air is discharged from the plurality of holes of the discharge plate and the plurality of holes of the side panel while the discharge blade is in the closing position.
