Heat exchanger and air conditioner indoor unit

Abstract

The present invention provides a heat exchanger and an indoor unit of an air conditioner that can both suppress a reduction in heat exchangeability and relax the error tolerance of the attachment angle of the heat exchange units. The indoor heat exchanger is a heat exchanger that is formed by connecting a plurality of heat exchangers disposed in the indoor unit of an air conditioner, and includes a first indoor heat exchanger, a second indoor heat exchanger, a third indoor heat exchanger and a fourth indoor heat exchanger. The third indoor heat exchanger is connected at an angle to one end of the first indoor heat exchanger and the second indoor heat exchanger. The fourth indoor heat exchanger is connected at an angle to another end of the first indoor heat exchanger and the second indoor heat exchanger. Then, the third indoor heat exchanger and the fourth indoor heat exchanger will have the same approximate height.

1 . A heat exchanger formed to be connected to a plurality of heat exchange units, and which is disposed in an indoor unit of an air conditioner, comprising: 
 a first heat exchange unit;    a second heat exchange unit that is connected at an angle with one end of the first heat exchange unit; and    a third heat exchange unit that is connected at an angle with another end of the first heat exchange unit;    wherein the second heat exchange unit and the third heat exchange unit have approximately the same length.    
     
     
         2 . The heat exchanger disclosed in  claim 1 , wherein the first heat exchange unit has an approximate inverted V shape in cross-section; and 
 the second heat exchange unit and the third heat exchange unit respectively extend downward from front and rear lower ends of the first heat exchange unit.    
     
     
         3 . The heat exchanger disclosed in  claim 1 , wherein 
 the heat exchanger is symmetrical from front to rear, and the second heat exchange unit and the third heat exchange unit are symmetrical from front to rear.    
     
     
         4 . An indoor unit of an air conditioner, comprising: 
 the heat exchanger disclosed in  claim 1;  and    a ventilation fan that is disposed so as to be covered by the heat exchanger.    
     
     
         5 . An indoor unit of an air conditioner, comprising: 
 a ventilation fan;    the heat exchanger disclosed in  claim 1  that covers front, upper and rear portions of the ventilation fan, and is disposed so that a lower front end and a lower rear end of the heat exchanger are at a height of an apex of the ventilation fan or lower;    a first drain pan that is disposed below the lower front end of the heat exchanger;    a second drain pan that is disposed below the lower rear end of the heat exchanger; and    a drain path through which drain water discharged from the first drain pan and the second drain pan passes;    wherein the first drain pan and the second drain pan are disposed at a same approximate height.    
     
     
         6 . The indoor unit of an air conditioner disclosed in  claim 5 , wherein 
 the heat exchanger has an approximate inverted V shape in cross-section.    
     
     
         7 . The indoor unit for an air conditioner disclosed in  claim 5 , wherein 
 the lower front end and the lower rear end of the heat exchanger are positioned at a same approximate height.    
     
     
         8 . The indoor unit of an air conditioner disclosed in  claim 5 , wherein 
 the heat exchanger has a shape that is symmetrical from front to rear.
