Document Type and Number:
WIPO Patent Application WO/2019/193697
Kind Code:
A1
Abstract:
This rotary compressor comprises: a compression mechanism unit that compresses a refrigerant inside a sealed container; and an electric motor that is disposed on the upper side of the compression mechanism unit. The compression mechanism unit includes: first to third refrigerant compression units that are disposed between a first bearing and a second bearing, at intervals from each other in the axial direction of the sealed container; a first intermediate partitioning panel that is interposed between the first refrigerant compression unit and the second refrigerant compression unit; a second intermediate partitioning panel that is interposed between the second refrigerant compression unit and the third refrigerant compression unit; and a rotation shaft to which a rotor of the electric motor is fixed. The compression mechanism unit is fixed to the sealed container by a pair of fixing units which are provided at two locations spaced apart from each other in the axial direction of the rotation shaft, and the center of gravity of a structure comprising the compression mechanism unit and the rotor of the electric motor is positioned between the pair of fixing units.
