Definitions

  • the present invention relates to a hermetic compressor suitable for use in cooling devices.
  • hermetic compressors In hermetic compressors, the refrigerant is sucked from and pumped back to the refrigeration cycle by means of a piston running in a cylinder.
  • One of the important factors determining the operating performance of hermetic compressors is the amount and temperature of the refrigerant gas entering the cylinder during the sucking action of the piston. Increased temperature of the refrigerant gas sucked from the refrigeration cycle causes a reduction in the amount of refrigerant gas entering the compression chamber of the cylinder, resulting in decrease in the volumetric efficiency and capacity of the compressor. Excessively increased temperature at the inlet of the cylinder causes an increase also in the body temperature of the cylinder, adversely affecting the compression process.
  • a suction muffler (10') is used to reduce the level of the noise originating from the refrigerant sucked from the refrigeration cycle.
  • the refrigerant gas flowing from the refrigeration cycle into the suction muffler (10') in the compressor (1') is transmitted by means of a muffler head (8') (suction plenum) into the cylinder (4').
  • the suction muffler (10') is structurally positioned in the vicinity of the motor (3') due to the space constraint and the temperature of the refrigerant gas passing through the suction muffler (10') increases due to the heat transfer from the motor (3').
  • the suction muffler (10') has a hollow structure and is produced from a hard plastic material, and occupies a considerable space in the casing (2'), and may sustain damage by hitting the casing (2') due to the shock occurring during the operation of the compressor (1') and transportation of the cooling device.
  • the International Patent Application No. WO2007015223 relates to a hermetic compressor wherein a refrigerant-tight connection is provided between a connection tube produced from a soft and elastic material and the muffler inlet tube produced from hard plastic.
  • US5252035 relates to a hermetic compressor wherein an elastic connection is provided between the suction muffler and the suction tube.
  • JPH01244180 relates to a hermetic compressor wherein a flexible connection with high molecular alloy is provided between the suction tube and the inlet of the suction muffler.
  • the aim of the present invention is the realization of a compressor comprising an elastic suction muffler that provides the attenuation of the noise arising from the refrigerant fluid returning from the refrigeration cycle.
  • the suction muffler used in the compressor of the present invention comprises a suction tube that is produced from a silicon-based elastic material and that connects the inlet tube providing the entry of the refrigerant in gas state returning from the refrigeration cycle into the casing and the muffler head that delivers the refrigerant to the cylinder.
  • the suction tube has a bent structure so as to move away from the motor.
  • the suction muffler comprises muffler chambers that are produced from the same material as the suction tube as a single piece with the suction tube and that are joined symmetrically to the right and left of the lateral outer surface of the suction tube.
  • the elastic muffler chambers disposed on two sides of the elastic suction tube provide the attenuation of the noise level.

  • the refrigerant in gas state leaving the evaporator (not shown in figures) disposed in the refrigeration cycle is sucked through the inlet tube (7) into the casing (2) of the compressor (1) and passes through the suction tube (9) of the suction muffler (10) and is transferred directly to the cylinder (4) by means of the muffler head (8) (suction plenum).
  • the suction muffler (10) is entirely produced from an elastic material and thus, significant advantages are achieved compared with the state of the art structures produced from hard plastic especially in terms of resistance to cracking and breaking.
  • the bent suction tube (9) enables the suction muffler (10) to be moved away from the stator that is the most heated component of the motor (3), thus reducing the heat transfer from the motor (3) to the suction muffler (10).
  • the suction tube (9) also contributes to the attenuation of the flow-induced noise by means of the elastic and bent structure thereof.
  • the suction muffler (10) is produced from an elastomer material containing silicone, for example silicone rubber with 60 to 70 Shore hardness.
  • the suction muffler (10) is fixed to the muffler head (8) by adhesion.

  • the COP (coefficient of performance) value is improved.
  • the elastic muffler chambers (11) disposed on two sides of the elastic suction tube (9) provide the attenuation of the noise level.
