Definitions

  • This invention relates to a hermetic compressor, specifically a discharge passage for a refrigerant and a lubricating oil.
  • a hermetic compressor of a type to which the present invention relates comprises a scroll unit arranged inside a hermetic container to perform a process of sucking in, compressing and discharging a refrigerant, and supplies a lubricating oil to the scroll unit and a scroll-unit driving part.
  • the lubricating oil not only lubricates sliding surfaces of the scroll unit, bearings, etc., but also seals the sliding surfaces.
  • the lubricating oil is held in an oil holding chamber at the bottom of the hermetic container and circulates inside the hermetic container, temporarily mixing with the refrigerant.
  • the refrigerant is discharged from the hermetic container through a discharge pipe fitted at the top of the hermetic container.
  • the hermetic compressor requires a device provided above the scroll unit to guide the lubricant oil and refrigerant discharged from the scroll unit, toward the oil holding chamber at the bottom of the hermetic container, thereby preventing them from flowing directly into the discharge pipe. This results in an increase in components, and the hermetic compressor is likely to have a complicated structure.
  • the configurations disclosed in the aforementioned patent documents can reliably guide the lubricating oil and refrigerant toward the oil holding chamber at the bottom of the hermetic container by virtue of having the oil discharge passage or the like, but do not ensure that the lubricating oil and the refrigerant are satisfactorily separated from each other, and thus, are still likely to experience the discharge of a large amount of the lubricating oil with the refrigerant, and problems caused by this, such as unsatisfactory lubrication and a reduction in thermal efficiency.
  • the fitting of the discharge pipe at the body of the hermetic container accompanies a problem of how to discharge the refrigerant smoothly and efficiently from the hermetic container, minimizing its interference with the components of the hermetic compressor.
  • An object of the present invention is to provide a hermetic compressor which has a simplified structure and can satisfactorily separate a lubricating oil from a refrigerant and efficiently discharge the refrigerant from a hermetic container.
