Abstract

An outdoor unit includes a housing having a bottom panel, an outdoor heat exchanger disposed inside the housing, a fan disposed inside the housing, a fan motor which is disposed inside the housing and drives the fan, a fan motor supporting plate disposed inside the housing more to the front than the outdoor heat exchanger and supports the fan motor, and a heater at least partially disposed on or around the fan motor supporting plate.

1 . An outdoor unit for an air-conditioning device comprising:
 a housing which includes a bottom panel;   an outdoor heat exchanger which is disposed inside the housing;   a fan which is disposed inside the housing;   a fan motor which is disposed inside the housing and configured to drive the fan;   a fan motor supporting plate which is disposed inside the housing more to front than the outdoor heat exchanger and supports the fan motor; and   a heater which is at least partially disposed at one of a position on the fan motor supporting plate and a position around the fan motor supporting plate.   
     
     
         2 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater extends in an up and down direction, and is bent at one of a position of an upper portion of the fan motor supporting plate and a position around the upper portion of the fan motor supporting plate to form an inverted U shape as seen in a front view. 
     
     
         3 . The outdoor unit for an air-conditioning device of  claim 1 , wherein an upper plate is connected to the fan motor supporting plate in an upper portion of the fan motor supporting plate, and the heater is further provided at one of a position on the upper plate and a position around the upper plate. 
     
     
         4 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the fan motor supporting plate is mounted on the bottom panel, and the heater is further provided on an upper surface of the bottom panel. 
     
     
         5 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the fan motor supporting plate includes a plurality of the fan motor supporting plates. 
     
     
         6 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater is implemented using a hot gas bypass pipe which directly supplies to the outdoor heat exchanger at least a part of a refrigerant discharged from a compressor which is disposed in the housing.
