Abstract
A refrigerator and a noise-reducing device mounted thereto are disclosed. The disclosed noise-reducing device, which comprises a hollow resonance chamber and a tubular acoustic filter inserted into the resonance chamber, is mounted at the side surface of a machine compartment, whereby not only heat due to the operation of a compressor is charged out of the machine compartment, but also noise transmitted from the compressor to the outside of the machine compartment is reduced through diffraction and resonance effects.

1-20. (canceled)
A refrigerator comprising:
- a mechanism chamber having a lateral wall that defines a ventilation hole configured to discharge air from the mechanism chamber to an outside of the mechanism chamber;
- and
- a noise-reducing device that is disposed adjacent to the ventilation hole and defines a communication hole in communication with the ventilation hole, the noise-reducing device having a hollow shape with a predetermined inner space, and
- wherein the noise-reducing device comprises a frame that defines a plurality of hollow portions that are arranged around the ventilation hole.
A noise-reducing device configured to be disposed at a first lateral surface of a mechanism chamber of a refrigerator, wherein the first lateral surface defines a first hole, the noise-reducing device comprising:
- a plurality of covers that define a resonance chamber and are configured to be disposed at a position corresponding to the first hole defined at the first lateral surface of the mechanism chamber, the plurality of covers having a shape corresponding to the first hole;
- and
- an acoustic filter that passes through the resonance chamber and has a hollow tube shape,
- wherein the noise-reducing device defines one or more holes that are in communication with the first hole defined at the first lateral surface of the mechanism chamber.
