Abstract
Disclosed are a reciprocating compressor and a refrigerator having the same. The reciprocating compressor comprises a casing, one reciprocating motor mounted at a frame unit provided in the casing for generating a linear-reciprocation driving force, a first compression unit for compressing a refrigerant directly sucked without passing through the inside of the casing by receiving the driving force of the reciprocating motor, and a second compression unit for mixing a refrigerant introduced into the casing and a refrigerant discharged from the first compression unit and then compressing the mixed refrigerant once more by receiving the driving force of the reciprocating motor. Accordingly, a refrigerant is consecutively compressed two times, components are simplified, and the compressor is easily controlled. Also, the refrigerator having the reciprocating compressor decreases a load of the reciprocating compressor thereby to enhance the efficiency of the refrigerator.
