Definitions

  • the present invention relates to a hermetic compressor utilized in cooling devices.
  • a suction muffler made of plastic material is used in attenuating the noise resulting from the refrigerant fluid and the refrigerant vapor with decreased temperature and pressure received from the evaporator is delivered to the suction muffler or the suction volume on the cylinder head by means of an elastic connection duct without being mixed with the overheated gases within the compressor casing.
  • the refrigerant fluid delivered from the evaporator since the refrigerant fluid delivered from the evaporator is not mixed with the hot gases within the compressor casing, it reaches the cylinder unheated.
  • pressure losses increase as it flows through the connection duct and the power needed for the start-up of the compressor increases, adversely affecting the performance.
  • connection ducts are supported by additional connection parts to be able to function under vibrational and high temperature conditions for long periods of time; however these additional parts make the assembly of the compressor more difficult, sufficient performance cannot be achieved due to the small size of the casing and other geometric limitations.
  • connection ducts connecting the compressor inlet and the suction muffler have to be produced of an elastic and leak-proof material since they have to function in an overheated environment like the compressor casing for long periods of time and for attenuating the vibrational movements.
  • elements that can provide a certain elasticity are used in the production of the connection ducts joining the vibrational components.
  • the flexible connection ducts are attached to a rigid duct within the compressor and after some period of time deformation is observed at the joints of flexible and rigid ducts under the environmental conditions of overheated gases within the compressor and the desired leak-proofing and elasticity cannot be achieved.
  • a direct suction system is explicated which comprises a flange arranged with a certain angle to the suction connector at the inlet of the suction muffler, a telescopic tube having a leading end being in full contact with this flange, and a helical spring used for stabilizing the telescopic tube.
  • the aim of the present invention is the realization of a compressor in which the circulating fluid returning from the refrigerant cycle is delivered to the suction muffler within by means of a leak-proof connection.
  • the circulating fluid returning from the refrigerant cycle enters into the compressor by means of a compressor inlet pipe and is delivered from here to the suction muffler and the cylinder head where it is sucked and pumped.
  • a connection pipe made of an elastic material such as rubber, between the compressor inlet pipe and the suction muffler is connected to the muffler inlet pipe having a rigid structure made of hard plastic material such that it is leak-proof and undislocatable by the motor vibrations in time.
  • the connection pipe is joined by over injection to the muffler inlet pipe placed in an injection mould, forming a connection that is not affected by the hot gases within the environment of the compressor casing.
  • a rigid muffler inlet pipe using additional connecting elements such as adhesives is not necessary. In fact, a more durable connection is achieved than the implementations wherein such elements are utilized.

  • the compressor (1) comprises a casing (2) that protects the movable components within, a cylinder (3) providing the suction and pumping of the circulating fluid, a cylinder head (4) situated on the cylinder (3), directing the sucked and pumped refrigerant fluid, a suction muffler (5) that attenuates the noise resulting from the circulating fluid, a compressor inlet pipe (6) that extends from outside the casing (2) to the interior, providing the entrance of the circulating fluid delivered from the evaporator, a muffler inlet pipe (7) one end of which extends into the suction muffler (5) allowing the entrance of the circulating fluid into the suction muffler (5), and a connection pipe (8) that connects the compressor inlet pipe (6) with the muffler inlet pipe (7), providing the delivery of the circulating fluid returning from the refrigerant cycle to the suction muffler (5) and attenuating the vibrations, having flexible or stepped structure, formed by over injection on
  • the muffler inlet pipe (7) is preferably produced as a single piece with the suction muffler (5) by injection moulding from TPE (thermoplastic elastomer) material that is rigid and not stretchable such as PBT (Polybutylene terephthalate) or PA (poly amide).
  • TPE thermoplastic elastomer
  • PBT Polybutylene terephthalate
  • PA poly amide
  • connection pipe (8) injected over the muffler inlet pipe (7) is produced of a soft and elastic material such as natural or synthetic rubber or from TPE (thermoplastic elastomer) containing a rubber additive.
  • connection pipe (8) is injected into the injection mould and after the connection pipe (8) material running in the mould reaches the muffler inlet pipe (7), it is bonded around the muffler inlet pipe (7) by being plastered over and consequently a connection pipe (8) - muffler inlet pipe (7) joint is formed which is durable in the overheated gas environment within the casing (2) ( Figures 1 - 3).
  • the muffler inlet pipe (7) comprises an injection surface (9) that forms the outer surface of its end whereto the connection pipe (8) is bonded by plastering over, the surface roughness increased by sandblasting or threading methods and providing the over injected material to adhere, a barrier (10) behind the injection surface (9), ring shaped and surrounding the muffler inlet pipe (7), making a boundary for the material of the connection pipe (8) that flows by plastering over the injection surface (9 ( Figure 4).
  • connection pipe (8) comprises a coating extension (11) providing it to be joined to the injection surface (9), formed during the injection process, extending as an empty cylindrical shape outwards from the front of the connection pipe (8), and bearing on the barrier (10) by being plastered over the injection surface (9) ( Figure 5).
  • the coating extension (11) surrounds to plaster over the circumference of the injection surface (9), the surface roughness of which is increased and a more durable joint is attained between the connection pipe (8) and the muffler inlet pipe (7) during the injection process.
  • the muffler inlet pipe (7) comprises one or more injection channels (12) situated on the barrier (10), extending from one surface of the barrier (10) to the other, and providing the material of the connection pipe (8) that bears on the barrier (10) to enter from one surface of the barrier (10) and exit from the other during the injection process ( Figure 6).
  • connection pipe (8) comprises one or more injection extensions (13) formed by the connection pipe (8) material filling in the injection channel (12) in the barrier (10) after the coating extension (11) reaches the barrier (10) during the injection process and one or more injection caps (14) that are formed at the ends of the injection extensions (13) as the material continues to flow and overflows going out from the injection channel (12) during the injection process ( Figures 7 - 8).
  • the injection extensions (13) and the injections caps (14) serve as elastic connection elements fixing the coating extension (11) to the barrier (10). While the compressor (1) is operating, injection surface (9) - the coating extension (11) joint between the connection pipe (8) and the muffler inlet pipe (7) is supported, guaranteeing that the coating extension (11) is not dislocated from the injection surface (9) and hence the connection pipe (8) is not dislocated from the muffler inlet pipe (7) during the high amplitude vibrational movements, furthermore the injection extensions (13) and the injection caps (14) contribute to the attenuation of the vibrations.
  • connection pipe (8) By way of the connection pipe (8) being injected over the muffler inlet pipe (7) a durable and leak-proof connection pipe (8) - muffler inlet pipe (7) joint is formed that is not dislocated in the inner environment of the casing (2) by time and ease of assembly is achieved since utilization of other joining elements like glue, clamps etc. are not necessary.
