Abstract
A scroll compressor is provided, in which a fixed side discharge opening is formed eccentric from a geometrical center of an orbiting scroll toward an orbiting side discharge opening, so as to overlap the orbiting side discharge opening across a relatively wide area. This may reduce flow resistance between the orbiting side discharge opening and the fixed side discharge opening. Accordingly, a refrigerant compressed in a final compression chamber may be rapidly discharged without being blocked by an upper frame, while maintaining a proper discharge pressure. Since uniform pressure may be maintained in compression chambers positioned at both sides of the scroll compressor, input losses due to over-compression may be reduced.
Claims20
A scroll compressor, comprising:
- a hermetic container defining an inner space;
- a fixed scroll provided in the inner space of the hermetic container, the fixed scroll having a fixed wrap;
- an orbiting scroll provided in the inner space of the hermetic container, the orbiting scroll having an orbital wrap that is engaged with the fixed wrap of the fixed scroll so as to form a compression chamber therebetween as the orbiting scroll performs an orbital motion with respect to the fixed scroll;
- a rotation shaft having an eccentric portion that extends through the fixed scroll and is coupled to the orbiting scroll, wherein the eccentric portion radially overlaps the orbital wrap;
- and
- an orbiting side discharge opening formed in the orbiting scroll, wherein the orbiting side discharge opening guides refrigerant compressed in the compression chamber into the inner space of the hermetic container.
A scroll compressor, comprising:
- an orbiting scroll installed between a fixed scroll and a frame, and engaged with the fixed so as to form at least one compression chamber therebetween, the at least one compression chamber including a suction chamber, an intermediate pressure chamber and a discharge chamber consecutively formed from an outer end to an inner end of the at least one compression chamber as the orbiting scroll performs an orbital motion with respect to the fixed scroll;
- a suction opening formed at the fixed scroll, in communication with the suction chamber;
- a first discharge opening formed at the orbiting scroll, in communication with the discharge chamber;
- and
- a second discharge opening formed at the frame, in communication with the first discharge opening,
- wherein the first discharge opening and the second discharge opening are formed at positions such that the first and second discharge openings always at least partially overlap each other.
A scroll compressor, comprising:
- a hermetic container;
- a fixed scroll fixed in the hermetic container, the fixed scroll having a fixed wrap;
- an orbiting scroll having an orbital wrap formed at a first surface thereof, the orbital wrap being engaged with the fixed wrap and forming a compression chamber therebetween as the orbiting scroll performs an orbital motion with respect to the fixed scroll;
- a frame configured to support a second surface of the orbiting scroll opposite the first surface thereof such that the orbiting scroll is positioned between the frame and the fixed scroll;
- a rotation shaft having an eccentric portion that passes through the fixed scroll and is coupled to the orbiting scroll, wherein the eccentric portion radially overlaps the orbital wrap;
- and
- a discharge opening formed in the fixed scroll, wherein refrigerant compressed in the compression chamber is discharged through the discharge opening.
