Abstract
Disclosed herein is a scroll compressor including a casing, a drive motor arranged in the casing, a shaft coupled to the drive motor, a main frame arranged under the drive motor, a fixed scroll arranged under the main frame, an orbiting scroll arranged between the main frame and the fixed scroll and engaged with the fixed scroll to form a compression chamber with the shaft eccentrically coupled to the orbiting scroll, a discharge cover coupled to the fixed scroll to form a closed space, a discharge port formed in the fixed scroll to connect the compression chamber and the closed space, and a discharge hole passing through the main frame and the fixed scroll, wherein an inlet and an inner portion of the discharge hole have different cross-sectional areas. The scroll compressor can reduce the noise caused by movement of the refrigerant by improving the structure of the discharge holes.
