Abstract

An outdoor unit of an air conditioning device in which a heat exchanger is arranged in a bottom plate in a substantially rectangular parallelepiped shape casing including a top plate, side plates, and the bottom plate is provided. The heat exchanger is mounted on a plurality of expanded portions formed in the bottom plate. A first drainage hole through which a drainage fluid from the heat exchanger is discharged to an exterior is formed in each of the expanded portions, and a second drainage hole smaller than the first drainage hole is formed in the bottom plate under the heat exchanger excluding the expanded portions.

Claims

exact text as granted — not AI-modified
1 .- 5 . (canceled) 
     
     
         6 . An outdoor unit of an air conditioning device in which a heat exchanger is arranged in a bottom plate in a substantially rectangular parallelepiped shape casing including a top plate, side plates, and the bottom plate, wherein
 the heat exchanger is mounted on a plurality of expanded portions formed in the bottom plate,   a first drainage hole through which a drainage fluid from the heat exchanger is discharged to an exterior is formed in each of the expanded portions,   a second drainage hole smaller than the first drainage hole is formed in the bottom plate under the heat exchanger excluding the expanded portions, and   the first drainage hole is formed at a position close to the windward side of an airflow passing through the heat exchanger in the expanded portion.   
     
     
         7 . The outdoor unit of the air conditioning device according to  claim 6 , wherein
 the second drainage hole is formed between the adjacent expanded portions.   
     
     
         8 . The outdoor unit of the air conditioning device according to  claim 6 , wherein
 the expanded portions are formed in a long circle shape and arranged at predetermined intervals along a planar shape of the heat exchanger.   
     
     
         9 . The outdoor unit of the air conditioning device according to  claim 8 , wherein
 the first drainage hole is a long hole, and is formed in each of the expanded portions in such a manner that a long axis of the long hole is along the longitudinal direction of the expanded portion.   
     
     
         10 . The outdoor unit of the air conditioning device according to  claim 7 , wherein
 the expanded portions are formed in a long circle shape and arranged at predetermined intervals along a planar shape of the heat exchanger.
