Abstract
A scroll compressor includes a fixed scroll, an orbiting scroll orbiting the fixed scroll to perform compression on a refrigerant, a discharge cover provided at an upper end of the fixed scroll and guiding discharge of a compressed refrigerant, a first discharge chamber from which the compressed refrigerant is discharged; a second discharge chamber communicating with the first discharge chamber and separating oil from the discharged refrigerant, and a third discharge chamber communicating with the second discharge chamber and guiding discharge of the separated refrigerant.
Claims19
A scroll compressor, comprising:
- a fixed scroll;
- an orbiting scroll configured to orbit the fixed scroll to perform compression on a refrigerant;
- a discharge cover provided at an upper end of the fixed scroll and guiding discharge of a compressed refrigerant;
- a cover member that covers the discharge cover and includes a discharge pipe to discharge the compressed refrigerant to outside;
- a first discharge chamber from which the compressed refrigerant is discharged;
- a second discharge chamber communicating with the first discharge chamber and separating oil from the discharged refrigerant;
- a third discharge chamber communicating with the second discharge chamber and guiding discharge of the separated refrigerant, and
- a discharge passage provided between the cover member and the discharge cover and that communicates with the third chamber and the discharge pipe, wherein the discharge cover includes an extending portion spaced apart from the discharge pipe and extended toward the fixed scroll and the extending portion defines the third discharge chamber.
A scroll compressor, comprising:
- a scroll compression unit including a fixed scroll and an orbiting scroll configured to orbit the fixed scroll and performing compression on a fluid;
- a discharge cover provided at an upper end of the scroll compression unit and serving to reduce noise generated when a compressed fluid is discharged;
- a plurality of discharge chambers guiding discharge of a fluid compressed in the scroll compression unit;
- an oil return path formed in the fixed scroll through which oil separated from a fluid returns while the fluid is flowing inside the plurality of discharge chambers;
- an oil return pipe communicated with the oil return path;
- and
- a coupling member coupled to a side surface of the fixed scroll and connecting the oil return pipe and the fixed scroll,
- wherein the oil return pipe is provided outside of the fixed scroll and extended downwardly.
A scroll compressor, comprising:
- a casing;
- a cover member having a discharge pipe and coupled to the casing;
- a division member dividing the inside of the casing and the cover member into a low-pressure portion and a high-pressure portion;
- a fixed scroll coupled to a lower side of the division member;
- an orbiting scroll configured to orbit the fixed scroll and performing compression on a fluid;
- a first discharge chamber formed at the fixed scroll and from which a compressed refrigerant is discharged;
- a second discharge chamber formed between the fixed scroll and the division member and separating oil from the discharge refrigerant;
- and
- a third discharge chamber communicating with the second discharge chamber and from which the separated refrigerant is discharged,
- wherein the division member includes a separation portion extended towards the fixed scroll from the division member, the separation portion defines the third chamber therein and is spaced apart from the discharge pipe, the division member and the cover member defines at least a portion of the high pressure portion.
