Abstract
A refrigerator includes a noise reduction device and a machine room that accommodates a condenser and a compressor. The noise reduction device includes a sensing unit configured to measure noise generated from the machine room of the refrigerator and a generating unit configured to output a sound signal having a frequency canceling or reducing the noise. The machine room is defined by a case that has a communication portion configured to communicate a fluid between an inside of the case and an outside of the case to thereby exchange heat between the fluid and the condenser and between the fluid and the compressor.
Claims16
A refrigerator machine room comprising:
- a case configured to accommodate a condenser and a compressor therein, the case defining a communication portion configured to communicate a fluid between an inside of the case and an outside of the case to thereby exchange heat between (i) the fluid and (ii) the condenser and the compressor;
- a sensing unit located at the case and configured to measure noise from the compressor;
- and
- a generator unit located at the case and configured to output a sound signal toward the communication portion, the sound signal having a frequency configured to cancel or reduce the noise;
- wherein the case comprises:
- a first side surface, and
- a second side surface that is spaced apart from the first side surface and faces the first side surface,
- wherein the communication portion comprises a first communication portion defined at the first side surface, and a second communication portion defined at the second side surface, and
- wherein the refrigerator machine room further comprises a fan located between the first communication portion and the second communication portion and configured to generate air flow in the case.
A refrigerator comprising:
- a body that defines a storage room therein;
- a case that defines a machine room vertically below the storage room;
- a condenser and a compressor that are accommodated in the machine room, the case defining a communication portion configured to communicate a fluid between an inside of the case and an outside of the case to thereby exchange heat between (i) the fluid and (ii) the condenser and the compressor;
- a sensing unit located at the case and configured to measure noise from the compressor;
- and
- a generator unit located at the case and configured to output a sound signal having a frequency configured to cancel or reduce the noise,
- wherein the communication portion comprises:
- a first communication portion defined at a first side surface of the case, and
- a second communication portion defined at a second side surface of the case that faces the first side surface and is spaced apart from the first side surface,
- wherein each of the first communication portion and that second communication portion comprises one or more openings configured to communicate air between the inside of the case and the outside of the case,
- wherein the compressor and the condenser are spaced apart from each other, and
- wherein the refrigerator further comprises a partition that is located between the compressor and the condenser and that divides the machine room into a first space accommodating the compressor and a second space accommodating the condenser.
