Outdoor unit, and refrigeration cycle device

Abstract

A pair of support column members, a motor support plate fixed thereto, at a support column fixing portion on each end, and that supports the fan motor. The motor support plate has a first plate that extends along a plane orthogonal with the front-rear direction, and has a motor insertion hole having the fan motor and a plurality of motor fixing portions disposed and arranged along an inside edge thereof, and a protrusion protruding to one side. The protrusion has an annular protrusion extending along the inside of said edge, and a reinforcement protrusion extending towards the support column fixing portion, from the annular protrusion. First and second imaginary lines extend in differing directions towards the support column fixing portion, from the motor fixing portion are assumed. A side surface of the reinforcement protrusion has first and second side surfaces that extend along the first and second imaginary lines.

1 . An outdoor unit of a refrigeration cycle device comprising:
 a fan motor having a rotation shaft, of which a rotation axis that extends in a front-rear direction is a center thereof;   a rotating blade that is fixed to the rotation shaft;   a pair of support column members that extend in a vertical direction, and that align in a left-right direction, and   a motor support plate that is fixed to each support column member out of the pair of support column members at a support column fixing portion provided on each end in the left-right direction, and that supports the fan motor between the pair of support column members,   wherein   the motor support plate has a first plate that extends along a plane that is orthogonal with the front-rear direction,   the first plate has
 a motor insertion hole which has the fan motor disposed on an inside thereof, 
 a plurality of motor fixing portions that are arranged along an inside edge of the motor insertion hole, and that fix the fan motor, and 
 a protrusion that protrudes to one side of the front-rear direction, 
   provided thereon,   the protrusion has
 an annular protrusion that extends along the inside edge of the motor insertion hole, and that has each motor fixing portion of the plurality of motor fixing portions disposed thereon, and 
 a reinforcement protrusion that extends towards the support column fixing portion, from the annular protrusion, 
   a first imaginary line and a second imaginary line which extend in directions that differ from one another towards the support column fixing portion, from the motor fixing portion of the plurality of motor fixing portions, as seen from the front-rear direction, are assumed, and   a side surface of the reinforcement protrusion has
 a first side surface that extends along the first imaginary line, and 
 a second side surface that extends along the second imaginary line. 
   
     
     
         2 . The outdoor unit according to  claim 1 , wherein
 the support column fixing portion has a first fixing portion that is screw-fixed to a support column member out of the pair of support column members, and   the first imaginary line passes through the first fixing portion, as seen from the front-rear direction.   
     
     
         3 . The outdoor unit according to  claim 2 , wherein
 the first imaginary line extends parallel to the left-right direction.   
     
     
         4 . The outdoor unit according to  claim 2 , wherein
 the support column fixing portion has two second fixing portions that are screw-fixed to the support column member, and   the second imaginary line passes between the two second fixing portions, as seen from the front-rear direction.   
     
     
         5 . The outdoor unit according to  claim 4 , wherein
 the plurality of motor fixing portions include a first motor fixing portion and a second motor fixing portion that are disposed so as to align in the vertical direction,   two second imaginary lines, one that extends from the first motor fixing portion and another that extends from the second motor fixing portion, intersect one another between the pair of second fixing portions, and   the side surface of the reinforcement protrusion has two second side surfaces that extend along each of the two second imaginary lines.   
     
     
         6 . The outdoor unit according to  claim 2 , wherein
 the support column fixing portion has a second fixing portion that is screw-fixed to the support column member, and   the second imaginary line passes through the second fixing portion, as seen from the front-rear direction.   
     
     
         7 . The outdoor unit according to  claim 1 , wherein
 a dimension in the vertical direction of the annular protrusion, is smaller than a dimension in the vertical direction of the support column fixing portion.   
     
     
         8 . The outdoor unit according to  claim 4 , wherein
 the first plate has the front-rear direction as a plate thickness direction thereof,   the motor support plate has   a second plate that is provided on each end on the left-right direction of the first plate, and has the left-right direction as a plate thickness direction thereof,   a second fixing portion of the two second fixing portions is provided on the first plate, and the first fixing portion is provided on the second plate.   
     
     
         9 . The outdoor unit according to  claim 1 , wherein the motor support plate has a bent plate that is bent in the front-rear direction, from the inside edge of the motor insertion hole. 
     
     
         10 . A refrigeration cycle device further comprising:
 the outdoor unit according to  claim 1 , and   a circulation path having a refrigerant flow therein.
