1. A scroll compressor, comprising:
a casing configured to accommodate refrigerant and oil;
a motor disposed in an inner space of the casing and configured to rotate a rotating shaft;
a compression unit disposed below the motor in the inner space of the casing and configured to compress the refrigerant based on rotation of the rotating shaft, the compression unit defining a discharge passage configured to discharge the compressed refrigerant to the inner space of the casing; and
a flow path guide that is disposed between the motor and the compression unit and separates a refrigerant flow path and an oil flow path from each other,
wherein the flow path guide defines a guide discharge hole that passes therethrough in an axial direction and is in fluid communication with the discharge passage of the compression unit,
wherein the flow path guide comprises a discharge guide protrusion that extends toward the motor and defines a guide passage therein facing the guide discharge hole, the guide passage having an annular shape surrounding the guide discharge hole,
wherein the flow path guide further comprises a guide body that has an annular shape and is coupled to the compression unit,
wherein the guide discharge hole is one of a plurality of guide discharge holes that are defined at the guide body and arranged in a circumferential direction of the flow path guide,
wherein the discharge guide protrusion is one of a plurality of discharge guide protrusions that are spaced apart from one another by a preset interval along the circumferential direction, the discharge guide protrusion extending from the guide body, and
wherein the guide passage is one of a plurality of guide passages that are defined in the plurality of discharge guide protrusions, respectively, each of the plurality of guide passages having an annular shape surrounding one of the plurality of guide discharge holes.

17. A scroll compressor comprising:
a casing configured to accommodate refrigerant and oil;
a motor disposed in an inner space of the casing and configured to rotate a rotating shaft;
a compression unit disposed below the motor in the inner space of the casing and configured to compress the refrigerant based on rotation of the rotating shaft, the compression unit defining a discharge passage configured to discharge the compressed refrigerant to the inner space of the casing; and
a flow path guide that is disposed between the motor and the compression unit and separates a refrigerant flow path and an oil flow path from each other,
wherein the flow path guide defines a guide discharge hole that passes therethrough in an axial direction and is in fluid communication with the discharge passage of the compression unit,
wherein the flow path guide comprises a discharge guide protrusion that extends toward the motor and defines a guide passage therein facing the guide discharge hole, the guide passage having an annular shape surrounding the guide discharge hole,
wherein the discharge passage is one of a plurality of discharge passages that are defined at the compression unit and spaced apart from one another along a circumferential direction of the compression unit,
wherein the flow path guide is one of a plurality of flow path guides that are spaced apart from one another along the circumferential direction,
wherein two adjacent flow path guides among the plurality of flow path guides define a communication space portion therebetween, and
wherein the plurality of flow path guides define (i) a plurality of guide discharge holes including the guide discharge hole and (ii) a plurality of guide passages including the guide passage.

19. An air conditioner comprising:
a condenser;
an expansion apparatus;
an evaporator; and
a scroll compressor comprising:
a casing configured to accommodate refrigerant and oil,
a motor disposed in an inner space of the casing and configured to rotate a rotating shaft,
a compression unit disposed below the motor in the inner space of the casing and configured to compress the refrigerant based on rotation of the rotating shaft, the compression unit defining a discharge passage configured to discharge the compressed refrigerant to the inner space of the casing, and
a flow path guide that is disposed between the motor and the compression unit and separates a refrigerant flow path and an oil flow path from each other,
wherein the flow path guide defines a guide discharge hole that passes through the flow path guide in an axial direction and is in fluid communication with the discharge passage of the compression unit,
wherein the flow path guide comprises a discharge guide protrusion that extends toward the motor and defines a guide passage therein facing the guide discharge hole, the guide passage having an annular shape surrounding the guide discharge hole,
wherein the flow path guide further comprises a guide body that has an annular shape and is coupled to the compression unit,
wherein the guide discharge hole is one of a plurality of guide discharge holes that are defined at the guide body and arranged in a circumferential direction of the flow path guide,
wherein the discharge guide protrusion is one of a plurality of discharge guide protrusions that are spaced apart from one another by a preset interval along the circumferential direction, the discharge guide protrusion extending from the guide body, and
wherein the guide passage is one of a plurality of guide passages that are defined in the plurality of discharge guide protrusions, respectively, each of the plurality of guide passages having an annular shape surrounding one of the plurality of guide discharge holes.
