Definitions

  • the present invention relates to a reciprocating hermetic compressor for use in refrigeration appliance such as a domestic refrigerator and a refrigeration appliance having the same.
  • the present invention more particularly relates to an exhaust passage to an exhaust silencer of a reciprocating hermetic compressor.
  • a refrigeration appliance such as a domestic refrigerator typically utilizes a reciprocating hermetic compressor to convey the refrigerant from an evaporator to a condenser.
  • the reciprocating hermetic compressor generally comprises a compression chamber, an intake chamber, and an exhaust chamber.
  • the intake chamber is located on a downstream side of the evaporator whereas the exhaust chamber is located on an upstream side of the condenser.
  • the compression chamber is formed within the cylinder block.
  • the intake chamber and the exhaust chamber are separately formed within the cylinder head.
  • a valve plate is interposed between the cylinder block and the cylinder head. By virtue of the valve plate, the compression chamber is selectively brought into fluid connection with the intake chamber and the exhaust chamber.
  • the valve plate generally comprises an intake port and exhaust port.
  • the intake port and exhaust port are typically configured by diaphragm check valves which allow the refrigerant to flow only in a single direction.
  • the intake port fluidly connects the intake chamber with the compression chamber upon suction of a piston located in the compression chamber.
  • the exhaust port fluidly connects the compression chamber with the exhaust chamber upon compression of the piston.
  • the reciprocating movement of the piston induces pressure waves in the refrigerant, which have a detrimental effect on the components of the compressor. Therefore, the refrigerant in the exhaust chamber is initially guided through an exhaust passage to an exhaust silencer for attenuating the pressure pulsation of the refrigerant, prior to returning the exhaust refrigerant to a refrigeration circuit of the refrigeration appliance.
  • the exhaust passage is generally formed inside the cylinder block whereas the exhaust silencer is directly mounted onto the cylinder block.
  • the exhaust silencer has an inlet which is fluidly connected to the exhaust passage.
  • the outlet of the exhaust silencer is fluidly connected to an exhaust tube which returns the exhaust refrigerant to the refrigeration circuit.
  • the temperature of the refrigerant in the exhaust chamber is considerably higher than the temperature of the refrigerant in the intake chamber due to the compression effectuated to the refrigerant by the piston. Consequently, the excess heat of the refrigerant in the exhaust passage is partly released to the cylinder block, and therefrom transferred to other components of the compressor such as the compression chamber, the intake chamber, a motor and the like which are in the vicinity of the exhaust passage. Hence, an overall efficiency of the compressor decreases. Therefore, heat transfer from the exhaust refrigerant to the aforementioned critical components of the compressor must be reduced.
  • US 5,288,212 (A ) discloses a hermetic reciprocating compressor which includes an exhaust chamber and an intake chamber wherein the cover walls of the exhaust chamber and an intake chamber are spaced apart from each other by a predetermined clearance.
  • a thermal insulation plate is installed in the intake chamber.
  • European Patent Application EP 1 942 274 A1 discloses a compressor for a car conditioner comprising a rear housing with a suction chamber and a discharge chamber that communicate via a valve plate with cylinder bores in a cylinder block.
  • a muffler is formed by a cylindrical wall formed on the outer surface of the cylinder block, and a communication passage is formed through the cylinder block, the valve plate and the rear housing to communicate the muffler with the discharge chamber.
  • An objective of the present invention is to provide a reciprocating hermetic compressor, and a refrigeration appliance having the same, which overcomes the aforementioned problems, and effectively reduces heat transfer from the exhaust refrigerant to the critical components of the compressor.
  • This objective has been achieved by the reciprocating hermetic compressor according to the present invention as defined in claim 1, and the refrigeration appliance according to the present invention as defined in claim 15. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
  • the exhaust silencer for attenuating pressure pulsation of a refrigerant received from the exhaust chamber is separately provided from the cylinder block and the cylinder head.
  • the compressor according to the present invention further comprises a metal silencer tube for guiding the refrigerant from the exhaust chamber to the exhaust silencer and a metal mounting piece having a hollow part fluidly joined to an opening of an end portion of the silencer tube which are together form-fittingly embedded into a notch formed into the cylinder block, wherein the hollow part is arranged in fluid communication with the exhaust chamber via a through hole formed in the valve plate.
  • the silencer tube between the mounting piece and the exhaust silencer is installed external to the cylinder block.
  • the refrigerant in the exhaust chamber is fed into the remote exhaust silencer without contacting the cylinder block. Consequently, the aforementioned compressor components remain at relatively low operating temperatures. With each stroke of the piston, more refrigerant can be trapped into the compression chamber. Thereby, the volumetric efficiency of the compressor increases.
  • the exhaust silencer is directly installed between the metal silencer tube and an exhaust tube which leads to an outside of the compressor housing. Thereby, any mechanical parts necessary for mounting the exhaust silencer onto the cylinder block have been dispensed with. Moreover, a compact compressor has been attained.
  • a thermal insulation material is arranged into the notch for thermally insulating the metal mounting piece from the cylinder block.
  • a resilient material is arranged into the notch for biasing the mounting piece towards the front surface of the cylinder block.
  • the resilient material also contributes to thermal insulation of the exhaust refrigerant.
  • the hollow part has a circular aperture.
  • the aperture has an area which is equal to or larger than an area of an inner cross-section of the silencer tube. Thereby, uniform flow impedance is attained. A pressure drop in the exhaust refrigerant flow is prevented and an efficient operation of the compressor is safeguarded.
  • the hollow part has an oval aperture. Thereby, a width of the hollow part is reduced without compromising flow impedance.
  • the notch is formed into the cylinder block at a position which opposes the exhaust chamber.
  • the through hole is formed in the valve plate at a position which establishes the shortest refrigerant flow path from the exhaust chamber to the hollow part. Thereby, the exhaust refrigerant is immediately guided into the silencer tube.
  • the notch is formed into an unthreaded portion of one anchor bore for receiving a fastening screw, particularly at a position opposing the exhaust chamber.
  • the through hole is similarly formed in the valve plate at a position which establishes the shortest refrigerant flow path from the exhaust chamber to the hollow part.
  • the notch is configured as a combination of a blind bore and a slot which are joined together.
  • the blind bore is formed into a front portion of the cylinder block whereas the slot is formed into a lateral portion of the cylinder block.
  • the mounting piece is seated in the blind bore whereas the silencer tube sideways clamped into said slot.
  • the mounting piece is a metal bushing fluidly joined to silencer tube by a welding joint.
  • a base portion of the bushing is gas-tightly closed by a metal plate.
  • a base portion of the metal bushing is only partly closed by a metal plate which has an annular opening for a screw to penetrate into a threaded portion of anchor bore when fastening the cylinder parts to each other.
  • a flat ring gasket is arranged on a base portion of the metal bushing for gas-tightly sealing a refrigerant flow path.
  • a head gasket is interposed between the cylinder block and the valve plate and another head gasket is interposed between the valve plate and the cylinder head.
  • Both head gaskets have respective through holes opposing the through hole in the valve plate for providing a refrigerant flow path from the exhaust chamber to the mounting piece.
  • the cylinder head is made of metal, preferably aluminum.
  • the aluminum cylinder head has improved corrosion resistance.
  • both the silencer tube and the mounting piece are made of metal, preferably steel. Thereby, the silencer tube can be easily joined to the mounting piece by welding. Such welding joint is robust and also reliable in view of gas-tightness.
