Abstract
The present invention relates to a compressor comprising: a muffler that provides a sealed space for guiding a refrigerant; and a resonator provided in the muffler and forming cavities separate from the sealed space to decrease vibration and noise caused by the refrigerant.
Claims18
A compressor comprising:
- a case including a discharge outlet defined at one side of the case, the discharge outlet being configured to discharge a refrigerant to an outside of the case;
- a rotary shaft disposed in the case;
- a driving unit coupled to the case and configured to rotate the rotary shaft;
- a compression unit coupled to the rotary shaft and configured to compress the refrigerant;
- a muffler that is coupled to the compression unit and defines a sealed space configured to supply the refrigerant toward the discharge outlet;
- and
- a resonator disposed in the muffler, the resonator defining a cavity that is separate from the sealed space and configured to reduce vibration or noise of the compressor,
- wherein the resonator includes:
- a resonant cover coupled to the muffler, the resonant cover defining the cavity,
- resonant holes defined through the resonant cover and configured to allow the vibration or noise to be communicated to the cavity, and
- a partition that divides the cavity into a plurality of cavities, each cavity divided by the partition being configured to counterbalance or absorb different frequencies corresponding to the vibration or noise,
- wherein the muffler includes:
- a coupling body coupled to the compression unit, and
- an accommodating body that extends from the coupling body and defines the sealed space, and
- wherein the partition includes a partition rib that extends from an outer circumferential surface of the rotary shaft toward an inner circumferential surface of the accommodating body. the partition rib dividing the cavity into the plurality of cavities.
