Abstract
Disclosed is a refrigerator having a noise reduction structure. According to the refrigerator, a branch pipe for reducing the intensive noise occurring from an impeller part is provided to a discharge pipe connected so that the refrigerant is discharged in a direction of a condenser from the impeller part. Therefore, the traveling sound wave of the noise traveling along the discharge pipe and the reverse sound wave traveling toward the branch pipe provided to the outer periphery of the discharge pipe meet each other, so that the both sound waves are cancelled to reduce the noise.
