Reciprocating compressor

A reciprocating compressor comprising:

• a hermetic container forming a sealed space;
• a discharge pipe made of a first metal material and coupled to the hermetic container;
• a motor including a stator and a rotor, the motor being installed in the hermetic container to generate a rotational force;
• a compression unit including a connecting rod that converts a rotational force of the motor into a linear drive force, a piston connected to the connecting rod, and a cylinder into which the piston is movably inserted, the compression unit being configured to compress a refrigerant;
• and
• a discharge unit configured to discharge the refrigerant compressed in the compression unit,
• wherein the discharge unit includes:
• at least two discharge mufflers that are separately arranged;
• a first discharge hose connecting adjacent discharge mufflers of the at least two discharge mufflers;
• and
• a second discharge hose that connects a last stage discharge muffler of the at least two discharge mufflers positioned at a last stage on a discharge path of a gas to the discharge pipe,
• wherein the first discharge hose is formed of a flexible material, and
• wherein the second discharge hose is formed of a second metal material.
