Air conditioner

Abstract

Inside a blown-out air duct in the air conditioner through which conditioned air reaches a blowing-out port, there is provided a rectifying box having a air passage therein, for rectifying a flow of the conditioned air toward a predetermined flowing direction in order to prevent any dew condensation at the blowing-out port in the air conditioner. In the meantime, in order to suppress noise, rectifying plates for reducing an inflowing angle of air flowing into the fin tips of a heat exchanger are interposed between an axial fan and the heat exchanger for taking in the air from the axial fan for heat exchanging.

We claim:  
     
         1 . An air conditioner having an air duct through which temperature-conditioned air reaches a blowing-out port, said air conditioner comprising: 
 a rectifying mechanism having an air passage therein, for rectifying a flow of the conditioned air toward a predetermined flowing direction.    
     
     
         2 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism supplies the conditioned air in a predetermined quantity or more to a wall surface defining said air duct.  
     
     
         3 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is provided with an air quantity adjusting member for adjusting an air quantity passing through said air passage.  
     
     
         4 . An air conditioner as claimed in  claim 1 , wherein a member constituting said air passage of said rectifying mechanism is juxtaposed with a main stream of blown-out air.  
     
     
         5 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is disposed at a position at which blown-out air inside said air duct is deflected toward a different direction.  
     
     
         6 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is disposed in a guide vane base serving as the structure for fixing lateral air flowing direction adjusting vanes, said lateral air flowing direction adjusting vanes for laterally adjusting the direction of blown-out air in said air duct.  
     
     
         7 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is disposed in a unit box for a fan for producing blown-out air.  
     
     
         8 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is disposed in the vicinity of the portion where a plurality of air flowing direction adjusting pieces for adjusting the direction of blown-out air are oriented in directions different from each other.  
     
     
         9 . An air conditioner as claimed in  claim 1 , wherein said rectifying mechanism is molded integrally with any one of component parts constituting said air conditioner.  
     
     
         10 . An air conditioner including an axial fan for blowing air and a heat exchanger having cooling fins for taking in the air blown by said axial fan so as to perform heat exchanging, said air conditioner comprising: 
 rectifying means interposed between said axial fan and said heat exchanger, for reducing an inflowing angle of air flowing into the tips of the cooling fins of said heat exchanger.    
     
     
         11 . An air conditioner as claimed in  claim 10 , wherein said rectifying means is attached to said heat exchanger.  
     
     
         12 . An air conditioner as claimed in  claim 10 , wherein said rectifying means is fixed to a portion except said heat exchanger.  
     
     
         13 . An air conditioner as claimed in  claim 10 , wherein said rectifying means is disposed at a portion except a projection area of said axial fan onto said heat exchanger.  
     
     
         14 . An air conditioner as claimed in  claim 10 , wherein said axial fan includes a blade fixing portion for fixing a blade at substantially the center thereof, and said rectifying means is disposed within a projection area of said blade fixing portion onto said heat exchanger.  
     
     
         15 . An air conditioner as claimed in  claim 10 , wherein said rectifying means is constituted of a flat rectifying plate.  
     
     
         16 . An air conditioner as claimed in  claim 10 , wherein said rectifying means is constituted of a rectifying plate inclined on the suction side thereof toward said axial fan.  
     
     
         17 . An air conditioner including an axial fan for blowing air and a heat exchanger having cooling fins for taking in the air blown by said axial fan so as to perform heat exchanging, 
 some of said fins being inclined on the suction side thereof toward said axial fan.    
     
     
         18 . An air conditioner as claimed in  claim 17 , wherein some of said fins are inclined on the suction side thereof toward said axial fan at a portion except a projection area of said axial fan onto said heat exchanger.  
     
     
         19 . An air conditioner as claimed in  claim 17 , wherein said axial fan includes a blade fixing portion for fixing a blade at substantially the center thereof, some of said fins being inclined on the suction side thereof toward said blade within a projection area of said blade fixing portion onto said heat exchanger.
