    Abstract: A compressor includes a case, a driving motor including a stator mounted inside the case and a rotor disposed radially inward of the stator and rotatable, a centrifugation space defined inside the case by one side of the driving motor and the case, a discharge pipe passing through the case and defining a refrigerant inlet hole, a rotation shaft coupled to the rotor to rotate, a compressing portion defined at the other side of the driving motor, where refrigerant is compressed by rotation of the rotation shaft, and a rotating member disposed to spread a rotary power of the rotor to the centrifugation space, thereby providing a centrifugal force to refrigerant and oil. The rotating member is disposed at one side of the rotor to rotate integrally with the rotor.

    Abstract: A scroll compressor is provided that may include a first compression chamber, a second compression chamber separated from the first compression chamber, and having a greater compression ratio than the first compression chamber, a first discharge port that communicates with the first compression chamber and provided with a first discharge inlet and a first discharge outlet, and a second discharge port separated from the first discharge port, that communicates with the second compression chamber, and provided with a second discharge inlet and a second discharge outlet, the discharge outlet of at least one of the first discharge port or the second discharge port may have a larger sectional area than the discharge inlet. Accordingly, a discharge delay in each compression chamber may be prevented in advance, thereby suppressing compression loss.

    Abstract: A scroll compressor is provided that may include an orbiting scroll having an orbiting wrap, and which performs an orbiting motion; and a fixed scroll having a fixed wrap to form a compression chamber including a suction chamber, an intermediate pressure chamber, and a discharge chamber, by being engaged with the orbiting wrap. In a state in which the orbiting scroll and the fixed scroll are concentric with each other, when a distance between the orbiting wrap and the fixed wrap is defined as an orbiting radius, there exists an offset section having an interval larger than the orbiting radius, between a side surface of the orbiting wrap and a side surface of the fixed wrap which faces the orbiting wrap. With such a configuration, even if the fixed scroll or the orbiting scroll is transformed due to thermal expansion, interference between the fixed wrap and the orbiting wrap at a portion having a large transformation amount may be prevented. This may prevent a frictional loss or abrasion between the fixed wrap and the orbiting wrap. Further, this may restrict or minimize a gap between the fixed wrap and the orbiting wrap at an opposite side to the suction chamber, resulting in enhanced compression efficiency.

    Abstract: A scroll compressor is provided that may include a first scroll provided with a discharge port, a second scroll engaged with the first scroll to form a first compression chamber and a second compression chamber, and a rotational shaft provided with an eccentric portion eccentrically coupled to the first scroll or the second scroll The eccentric portion may overlap the first and second compression chambers in a radial direction. The discharge port may be provided with at least one discharge inlet and a discharge outlet The at least one discharge inlet may include a plurality of discharge inlets, which have different areas from each other, whereby a refrigerant of each compression chamber may be smoothly discharged, thereby preventing an over-compression loss due to a delay of discharge.

    Abstract: A compressor includes a casing that defines an oil storage space and an opening that discharges refrigerant to an outside of the casing, a rotatable shaft disposed in the casing, a driver coupled to an inner circumferential surface of the casing and configured to rotate the rotatable shaft, a compression assembly coupled to the rotatable shaft and configured to compress and discharge the refrigerant to an inside of the casing, a muffler coupled to the compression assembly and configured to guide the refrigerant discharged from the compression assembly toward the opening, where the muffler being is configured to exchange heat with the refrigerant, and a heat radiating member that is coupled to the muffler and extends to the oil storage space and contacts the oil in the oil storage space. The muffler is configured to exchange heat with the oil through the heat radiating member.

    Abstract: A compressor includes a casing configured to accommodate refrigerant and oil, a discharger disposed at a side of the casing and configured to discharge the refrigerant, a driver including a stator and a rotor, a rotation shaft that is coupled to the rotor and that extends in a direction away from the discharger, a compressing assembly that is coupled to the rotation shaft, that is configured to be lubricated with the oil, and that is configured to compress the refrigerant and discharge the compressed refrigerant in the direction away from the discharger, a muffler coupled to the compressing assembly and configured to guide the refrigerant to the discharger, and a bypassing portion disposed outside the casing and configured to transfer the refrigerant or the oil from the muffler to the discharger.
