HERMETIC COMPRESSOR WHICH PREVENTS THE INCREASE OF REFRIGERANT TEMPERATURE DUE TO OIL SEPARATING FROM REFRIGERANT, AND A REFRIGERATOR WHICH APPLIED WITH THE SAME

摘要

PURPOSE: A hermetic compressor and a refrigerator which applied with the same are provided to collect oil separating using a compressor and to prevent the backward flowing of the collected oil.;CONSTITUTION: A casing(10) has a sealed inner space and a connected to an intake pipe(13) and a discharging pipe(14). A drive motor(20) generates the driving force and is installed inside the inner space of the casing. A compressive unit(30) is installed inside the inner space of the casing and is operated by the drive motor in order to compress refrigerant. An oil separator divides the oil from the refrigerant discharged from the compressive unit. An oil pump(100) is combined in a crank shaft of the drive motor and collects the oil separating by the oil separator. An oil recovery pipe(300) is guides the separated oil to the oil pump by connecting the oil separator to the oil pump. A back flow preventing member(500) is installed on the oil recovery pipe and prevents the backward flowing of the oil to the oil separator from the oil pump.;COPYRIGHT KIPO 2010
