Definitions

  • the present invention relates to a hermetic compressor the production cost of which is decreased.
  • the refrigeration capacity of the hermetic compressor used in cooling devices like refrigerators varies depending on the motor power.
  • the motor power depends on the height of the stator stack disposed therein.
  • the stator stack is made up of magnetic laminations stacked one on top of the other.
  • stators having different number of laminations hence different heights are used.
  • the dimensions of the block disposed inside the compressor casing, supporting and/or bearing the basic mechanical elements like the cylinder, piston, crankshaft and piston rod are produced preferably in monotype by the producer in order to provide standardization in production and the monotype block is used for compressors having different refrigeration capacities.
  • the aim of the present invention is the realization of a hermetic compressor the production cost of which is decreased.
  • the hermetic compressor realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a stator stack produced by stacking laminations one above the other, a framework shaped block disposed on the stator stack, supporting the elements like cylinder, piston and crankshaft, more than one leg, extending from the block towards the stator stack, supporting the block over the stator stack and more than one protrusion, whereon the block legs are seated, configured by shaping the uppermost lamination of the laminations forming the stator stack.
  • the protrusions extend from the stator stack toward the block.
  • the protrusions are preferably camber shaped.
  • the desired stator stack height is obtained by configuring the protrusions on the lamination itself.
  • a separate elevating element between the stator stack and the leg is not necessary.
  • the height of the protrusion is adjusted according to the height of the stator stack that determines the refrigeration capacity of the compressor.
  • the total height of the stator stack and block legs is kept constant. Consequently, the parameters like the crankshaft length, height of the casing, location of suction duct inlet location that are variable for different types of compressors, remain the same for each compressor and standardization is provided in production.
  • the protrusion is configured by a simple method like deep drawing that is implemented on the uppermost lamination of the stator stack.
  • the protrusion is configured by cutting and bending the uppermost lamination of the stator stack.
  • the lamination whereon the protrusion is configured is thicker than the other laminations of the stator stack.
  • the strength of the protrusion is increased thereby strengthening support of the block on the stator stack.
  • the protrusion is configured on more than one upper laminations of the stator stack.
  • the strength of the protrusion is increased.
  • the distance between the base of the stator stack and upper surface of the block is kept constant by configuring the protrusion on the lamination forming the upper surface of the stator stack, without requiring a separate elevation element. Consequently, cost advantage is provided in production by only changing the height of the protrusion during production, by sharing the identically produced elements like the crankshaft, upper casing for each type of compressor.
  • Figure 1 – is the cross sectional view of a hermetic compressor.
  • Figure 2 – is the perspective view of a lamination.
  • the hermetic compressor (1) suitable for use in cooling devices like the refrigerator comprises a motor (7) that provides the operation thereof, a cylinder (8) providing the refrigerant fluid therein to be pumped, a piston (9) providing the refrigerant fluid to be compressed into the cylinder (8) hole and a crankshaft (10) that transfers the movement from the motor (7) to the piston (9).
  • the hermetic compressor (1) of the present invention comprises a casing (2), a stator stack (3) composed of laminations (L), disposed inside the casing (2), a block (4) disposed in the casing (2), placed on the upper surface of the stator stack (3), supporting and/or bearing the basic mechanical elements like cylinder (8), piston (9), crankshaft (10), more than one leg (5), seated on the stator stack (3) by extending from the block (4) to the upper surface of the stator stack (3) and supporting the block (4) on the stator stack (3) and more than one protrusion (6), formed by shaping at least one lamination (L) forming the upper surface of the stator stack (3), on which the legs (5) are seated.
  • the stator stack (3) produced by stacking the laminations (L) one above the other is disposed inside the casing (2) and the block (4) is seated on the stator stack (3).
  • Protrusions (6) are formed on the lamination (L) forming the upper surface of the stator stack (3) by using one of the metal shaping methods.
  • the length of the stator stack (3) can be easily changed by forming the protrusion (6) on the lamination (L) itself.
  • the legs (5) extending from the block (4) towards the stator stack (3) are seated on the protrusions (6).
  • the distance between the base of the stator stack (3) and the upper surface of the block (4) is kept constant by adjusting the height of the protrusions (6).
  • the height of the stator stack (3) can be increased, which is produced for compressors (1) having different refrigeration capacities, having different number of laminations (L) hence having different heights.
  • the crankshaft (10) the height of which is determined by the total lengths of the stator stack (3) and the block (4) leg (5), transferring the movement from the motor (7) to the piston (9), can be produced in monotype and is feasible to be used for different types of compressors (1).
  • cost advantage is provided in production.
  • the hermetic compressor (1) furthermore comprises a lower casing (14) and an upper casing (15) forming the casing (2), a suction muffler (11) disposed inside the casing (2), providing the noise resulting from the refrigerant fluid to be attenuated, an inlet duct (13) carrying the refrigerant fluid delivered from the evaporator in the refrigeration cycle, an inlet port (12) arranged on the suction muffler (11), providing the passage of the refrigerant fluid delivered from the inlet duct (13) to the suction muffler (11).
  • the casing (2) is produced from two parts, being the lower casing (14) and the upper casing (15).
  • the upper casing (15) can be produced with fixed length for different types of compressors (1). Consequently, the inlet port (12) of the suction muffler (11) can be aligned precisely with the inlet duct (13). Thus, occurrence of losses in the refrigeration capacity and/or efficiency of the compressor (1) is prevented.
  • the protrusion (6) is formed on the uppermost lamination (L) of the stator stack (3) by deep drawing method.
  • the height of the stator stack (3) is increased by forming the protrusion (6) by means of a simple shaping performed on the lamination (L).
  • the protrusion (6) is formed by cutting and bending the uppermost lamination (L) of the stator stack (3).
  • the thickness of the lamination (L) forming the uppermost surface of the stator stack (3) is more than the thickness of the other laminations (L).
  • Increasing the thickness of the lamination (L) provides the thickness of the protrusion (6) to also increase. Consequently, the strength of the protrusion (6) is increased against the force that arises upon mounting the block (4) and the stator stack (3) to each other and the tension and vibrations that occur during operation.
  • the protrusion (6) is formed by shaping the lamination (L) forming the upper surface of the stator stack (3) together with at least one lamination (L) disposed beneath that and the protrusions (6) are attached to each other by being aligned one above the other while the stator stack (3) is produced.
  • the strength of the protrusions (6) is increased by forming protrusions (6) on more than one lamination (L).
