Patent ID: 11378080

Abstract:
In a compressor, a sufficient insulation distance is ensured between a motor and a compression mechanism, and the amount of lubricating oil that flows out with refrigerant discharged from the compressor is reduced, while the volume of the compressor is reduced. The compressor includes: a compression mechanism that compresses refrigerant; a motor unit above the compression mechanism to drive the compression mechanism; a shell that houses the compression mechanism and the motor unit; and a lower insulating member between the compression mechanism and the motor unit. The motor unit includes a stator fixed to the shell, and a rotor spaced from an inner circumferential surface of the stator by a predetermined gap. The rotor has a rotor passage that causes spaces above and below the motor unit to communicate with each other, and the lower insulating member is in a region outward of the inner circumferential surface of the stator.
