Indoor unit and air conditioner

Abstract

An indoor unit of an air conditioner includes a blower that has an impeller that is rotatable around a rotation axis; a bell-mouth having an inflow port that opens to a first side in an axial direction of the rotation axis, and that is located on the first side of the blower; an electric components box that is located on the first side of the bell-mouth, and that has at least a portion thereof disposed so as to face the inflow port in the axial direction, and an air guide plate that is disposed so as to face the inflow port in the axial direction, and is disposed so as to face an inside of the electric components box in a radial direction with the direction of rotation being a center thereof.

1 . An indoor unit of an air conditioner comprises:
 a blower that has an impeller that is rotatable around a rotation axis;   a bell-mouth having an inflow port that opens to a first side in an axial direction of the rotation axis, and that is located on the first side of the blower;   an electric components box that is located on the first side of the bell-mouth, and that has at least a portion thereof disposed so as to face the inflow port in the axial direction, and   an air guide plate that is disposed so as to
 face the inflow port in the axial direction, and is disposed so as to 
 face an inside of the electric components box in a radial direction with the direction of rotation being a center thereof, wherein 
   a plate surface of the air guide plate faces the axial direction,   a surface that faces the first side out of the plate surface of the air guide plate is located on the first side more than a center of the electric components box in the axial direction, and   a surface that faces the first side out of the plate surface of the air guide plate is disposed on the same location as a surface of the first side of the electric components box in the axial direction.

         3 . An indoor unit of an air conditioner comprises:
 a blower that has an impeller that is rotatable around a rotation axis;   a bell-mouth having an inflow port that opens to a first side in an axial direction of the rotation axis, and that is located on the first side of the blower;   an electric components box that is located on the first side of the bell-mouth, and that has at least a portion thereof disposed so as to face the inflow port in the axial direction, and   an air guide plate that is disposed so as to
 face the inflow port in the axial direction, and 
 face an inside of the electric components box in a radial direction with the direction of rotation being a center thereof, wherein 
   a plate surface of the air guide plate faces an intersecting direction that is orthogonal to both the axial direction and the radial direction, and   a plurality of air guide plates that include the air guide plate are disposed with intervals therebetween in the intersecting direction.   
     
     
         4 . The indoor unit according to  claim 3 , wherein:
 the plurality of air guide plates are separately disposed in the intersecting direction from both ends of the intersecting direction in a portion out of the electric components box that overlaps with the inflow port as seen from the axial direction.   
     
     
         5 . The indoor unit according to  claim 3 , wherein:
 intervals between the adjacent air guide plates are the same over an entirety of the axial direction.   
     
     
         6 . (canceled) 
     
     
         7 . (canceled) 
     
     
         8 . The indoor unit according to  claim 1 , wherein:
 the air guide plate is attached to the electric components box.   
     
     
         9 . The indoor unit according to  claim 1 , wherein:
 the air guide plate is attached to the bell-mouth.   
     
     
         10 . An air conditioner comprises:
 the indoor unit according to  claim 1 , and   an outdoor unit.   
     
     
         11 . The indoor unit according to  claim 1 , wherein:
 the bell-mouth has an outflow port that opens to a second side that is opposite to the first side in the axial direction,   an inner edge of the outflow port is located on an inside in the radial direction more than an inner edge of the inflow port, and   at least a portion of the electric components box and the air guide plate overlap with the outflow port as seen from the axial direction.
