1. A hermetic compressor comprising:
a casing;
a motor inside the casing, and including a rotor, a stator, and a gap between the rotor and the stator;
a drive shaft configured to rotate with the rotor;
a compression unit below the motor and configured to compress refrigerant and discharge compressed refrigerant to an inside of the casing according to rotation of the drive shaft; and
an oil blocking guide above the motor and configured to rotate integrally with the rotor,
wherein the oil blocking guide includes:
an oil blocking plate formed in a disk shape,
an oil guide part extending upward and angling outward from an edge of the oil blocking plate to a diameter of the oil blocking guide, the oil guide part disposed above the gap of the motor, and
a support part connecting the oil blocking plate to the drive shaft so as to space the oil blocking plate from the rotor,
wherein the oil blocking plate and the oil guide part block upward movement of oil passing through the motor, and guide the oil passing through the motor to an inner circumferential surface of the casing through centrifugal force while the oil blocking guide is rotating.
