Problems solved by technology

However, the scroll compressor should be formed such that the fixed scroll is engaged with the orbiting scroll, and thus is difficult to manufacture compared with other compressors, and as a result, compound or two-stage scroll compressors have not been widely developed

Abstract

A compressor according to the present disclosure may include a container; a drive motor provided in the container; a crankshaft coupled to a rotor of the drive motor; a first scroll coupled to the crankshaft to receive a rotational force of the drive motor to perform an orbiting movement; a second scroll coupled to the first scroll to form a first compression unit and a second compression unit along with the first scroll; and a vane provided in the first scroll or second scroll to be brought into contact with the other side scroll to form the second compression unit, wherein the first compression unit is carried out in a scroll compression mode and the second compression unit is carried out in a rotary compression mode.

Description

technical field [0001] The present disclosure relates to a compressor, and more particularly, to a two-stage compressor having a scroll-side compression unit and a rotation-side compression unit. Background technique [0002] Generally, a refrigerant compressor may be applied to a vapor compression refrigeration cycle (hereinafter, abbreviated as "refrigeration cycle") such as a refrigerator, an air conditioner, and the like. As for the refrigerant compressor, a constant speed compressor driven at a predetermined speed or an inverter compressor whose rotational speed is controlled is introduced. [0003] Refrigerant compressors can generally be classified into hermetic compressors and open compressors, in which a driving motor, which is an electric motor, and a compression unit operated by the driving motor are disposed together inside a hermetic case space, while in an open compressor, the drive motor is provided separately outside the casing. Hermetic compressors are mai...
