Document Type and Number:
WIPO Patent Application WO/2018/208023
Kind Code:
A1
Abstract:
A scroll compressor according to the present invention comprises: a driving motor which comprises a stator fixed in an inner space of a casing, and a rotor rotating inside the stator, and which is equipped with an inner passage and an outer passage which penetrate in the axial direction; a rotation shaft rotating by being coupled to the rotor of the driving motor; a compression part comprising a first scroll provided under the driving motor, and a second scroll which forms a compression chamber by being engaged with the first scroll, is eccentrically coupled such that the rotation shaft overlaps with the compression chamber in a radial direction, and performs a circling motion with respect to the first scroll, thereby allowing a refrigerant compressed in the compression chamber to be discharged toward the inner space of the casing; a discharge tube in communication with an upper space, of the inner space of the casing, formed above the driving motor; an oil separation member provided in the upper space of the casing and separating oil from the refrigerant; and a guide member provided between the upper end of the driving motor and the lower end of the discharge tube and guiding the refrigerant mixed with the oil to the oil separation member.
