Scroll compressor with oil separation member

A scroll compressor comprising:

• a casing, including a sealed internal space;
• a drive motor that includes a stator located in the internal space in the casing, a rotor which rotates within the stator, and a flow passage that passes through the drive motor in an axial direction;
• a rotation shaft that is connected to the rotor of the drive motor and rotated by the drive motor;
• a compression unit that includes a first scroll disposed below the drive motor, and a second scroll connected to the rotation shaft and engaged with the first scroll to form a compression chamber while the second scroll performs an orbiting motion with respect to the first scroll, wherein orbital motion of the second scroll relative to the first scroll causes refrigerant compressed in the compression chamber to be discharged toward the internal space in the casing;
• a discharge pipe in fluid communication with an upper part of the internal space in the casing, the upper part of the internal space being formed above the drive motor;
• an oil separation member disposed in the upper part of the internal space in the casing, the oil separation member being configured to separate oil from the refrigerant;
• and
• a guidance member disposed between an upper end of the drive motor and a lower end of the discharge pipe, the guidance member being configured to guide the refrigerant with which the oil is mixed, to the oil separation member,
• wherein the oil separation member is connected to the discharge pipe, and
• wherein:
• an upper surface of the oil separation member is formed with a closed plate, and is connected to the discharge pipe,
• a flank surface of the oil separation member is formed with a mesh through which the refrigerant passes, resulting in the oil being separated from the refrigerant, and
• a lower surface of the oil separation member is formed with a ring-shaped plate of which a center portion is open.

• wherein the oil separation member is fixedly connected to an inner circumferential surface of the casing, and
• wherein the oil separation member includes a plate fixed to the inner circumferential surface of the casing, and a mesh having a shape of a ring or an arc is provided in a central portion of the plate.
