Outdoor unit for air-conditioning device

Abstract

An outdoor unit includes a housing having a front and side panel in which an opening is formed, a fan disposed in an air-sending device chamber formed inside the housing, an outdoor heat exchanger disposed in the air-sending device chamber, a bell mouth which is disposed in the air-sending device chamber and extends backwards from the periphery of the opening, and a heater which is disposed in the air-sending device chamber in which the bell mouth is disposed, and extends in the up and down direction.

1 . An outdoor unit for an air-conditioning device comprising:
 a housing which includes a front panel in which an opening is formed;   a fan disposed in an air-sending device chamber which is formed inside the housing;   an outdoor heat exchanger disposed in the air-sending device chamber;   a bell mouth which is disposed in the air-sending device chamber and extends backwards from a periphery of the opening; and   a heater which is disposed in the air-sending device chamber in which the bell mouth is disposed, and extends in an up and down direction.   
     
     
         2 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the outdoor heat exchanger is provided to extend along a side face of the housing which forms the air-sending device chamber, and the heater is disposed more to a side of the outdoor heat exchanger which is provided to extend along the side face of the air-sending device chamber than the bell mouth. 
     
     
         3 . The outdoor unit for an air-conditioning device of  claim 1 , further comprising:
 a compressor; and   a partition that divides an inner space of the housing into a plurality of spaces,   wherein the partition divides the inner space of the housing into a machine chamber which houses the compressor and the air-sending device chamber.   
     
     
         4 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater is provided to form an inverted U shape as seen in a side view. 
     
     
         5 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater is further provided on an upper surface of a bottom panel which forms the housing. 
     
     
         6 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater is provided to extend in a right and left direction in a portion above a top end of the bell mouth. 
     
     
         7 . The outdoor unit for an air-conditioning device of  claim 1 , wherein the heater includes a plurality of bent portions. 
     
     
         8 . 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.
