1. A scroll compressor comprising:
a casing;
a refrigerant suction pipe and a refrigerant discharge pipe that are connected to the casing;
a compression part disposed at the casing and configured to receive a rotational force of a motor through a rotating shaft and compress refrigerant in a compression chamber between a non-orbiting scroll and an orbiting scroll; and
a high and low pressure separation plate disposed at a side of the compression part in an axial direction and defining (i) a low-pressure part connected to the refrigerant suction pipe and (ii) a high-pressure part connected to the refrigerant discharge pipe, the high and low pressure separation plate defining a through hole through a central portion of the high and low pressure separation plate, the through hole being configured to guide the refrigerant discharged from the compression part toward the high-pressure part,
wherein the high-pressure part includes a discharge guide configured to guide the refrigerant discharged from the compression part to the refrigerant discharge pipe,
wherein the discharge guide extends from at least one of (i) an inner circumferential surface of the casing that defines the high-pressure part or (ii) a side surface of the high and low pressure separation plate that faces the high-pressure part from an opposite side to the inner circumferential surface of the casing that defines the high-pressure part
wherein the high and low pressure separation plate includes:
an inclined surface portion extending between a central portion of the high and low pressure separation plate and a rim of the high and low pressure separation plate and being downwardly inclined towards the low-pressure part from the central portion to the rim; and
a first protrusion protruding from a middle of the inclined surface portion in a circumferential direction and extending in a radial direction, and
wherein the discharge guide is disposed between the first protrusion and the through hole.
