Abstract
A scroll compressor includes oil in an oil storage space that is brought into direct contact with and stirred with a discharge refrigerant. The scroll compressor includes a fixed scroll, an orbiting scroll coupled to one side of the fixed scroll, and a discharge cover coupled to another side of the fixed scroll and provided with a muffler hole communicating with a refrigerant discharge space and the oil storage space.
Claims22
A scroll compressor comprising:
- a fixed scroll;
- an orbiting scroll disposed at a first side of the fixed scroll and configured to perform an orbiting motion relative to the fixed scroll and define a compression chamber between the orbiting scroll and the fixed scroll;
- a discharge cover disposed at a second side of the fixed scroll that is opposite to the first side of the fixed scroll;
- and
- a casing extending in a first direction and accommodating the fixed scroll, the orbiting scroll, and the discharge cover,
- wherein the discharge cover comprises:
- a cover bottom surface,
- a cover side portion extending from the cover bottom surface toward the fixed scroll, and
- a discharge space defined by the cover bottom surface, the cover side portion, and the fixed scroll,
- wherein the cover bottom surface and an inner circumferential surface of the casing are spaced apart from each other and define an oil storage space between the cover bottom surface and the casing, and
- wherein the cover bottom surface defines a muffler hole that is in fluid communication with the discharge space and the oil storage space.

A scroll compressor comprising:
- a fixed scroll including a fixed wrap;
- an orbiting scroll disposed at a first side of the fixed scroll and configured to perform an orbiting motion relative to the fixed scroll and define a compression chamber between the orbiting scroll and the fixed scroll, the orbiting scroll including an orbiting wrap configured to engage with the fixed wrap;
- a discharge cover disposed at a second side of the fixed scroll that is opposite to the first side of the fixed scroll;
- and
- a casing extending in a first direction and accommodating the fixed scroll, the orbiting scroll, and the discharge cover,
- wherein the discharge cover comprises:
- a cover bottom surface,
- a cover side portion extending from the cover bottom surface toward the fixed scroll, and
- a discharge space defined by the cover bottom surface, the cover side portion, and the fixed scroll,
- wherein the cover bottom surface and an inner circumferential surface of the casing are spaced apart from each other and define an oil storage space between the cover bottom surface and the casing, and
- wherein a muffler hole is defined through a connection portion between the cover bottom surface and the cover side portion, the muffler hole being in fluid communication with the discharge space and the oil storage space.

A scroll compressor comprising:
- a fixed scroll;
- an orbiting scroll disposed at a first side of the fixed scroll and configured to perform an orbiting motion relative to the fixed scroll, the orbiting scroll configured to be coupled to the fixed scroll and define a compression chamber with the fixed scroll;
- a discharge cover disposed at a second side of the fixed scroll that is opposite to the first side of the fixed scroll;
- and
- a casing extending in a first direction and defining a space for accommodating the fixed scroll, the orbiting scroll, and the discharge cover,
- wherein the discharge cover comprises:
- a cover bottom surface,
- a cover side portion extending from the cover bottom surface toward the fixed scroll and being spaced apart from an inner circumferential surface of the casing, and
- a discharge space defined by the cover bottom surface, the cover side portion, and the fixed scroll,
- wherein the cover bottom surface and an inner circumferential surface of the casing are spaced apart from each other and define an oil storage space between the cover bottom surface and the casing, and
- wherein the cover side portion defines a muffler hole that is in fluid communication with the discharge space and the oil storage space.
