Definitions

  • the present invention relates to a hermetically sealed compressor of a refrigeration appliance such as a domestic refrigerator.
  • the present invention particularly relates to the electric motor of the hermetically sealed compressor.
  • the present invention more particularly relates to the rotor of the electric motor.
  • Hermetically sealed compressors which are used in refrigeration appliances are commonly known.
  • the refrigeration appliances come with different refrigeration capacities.
  • the refrigeration capacity of the refrigeration appliance generally depends on the refrigeration capacity of the compressor used therein.
  • the hermetically sealed compressors having different refrigeration capacities are generally produced as a family of compressors in which the individual compressors differ from each other mainly through a small number of components such as the electric motor, and a small number of modifications made to the size of the cylinder bores, the pistons and the like. Other differences are generally kept minor such that the same or similar components can be used in the assembly of the individual compressors.
  • the electric motors with different electric powers have respectively different dimensions, and thus require a corresponding installation space inside the casing, in particular below the cylinder housing.
  • Prior art document BR9201761 describes a hermetic compressor including a bearing for supporting a vertical eccentric shaft that is fixed to the rotor of an electric motor.
  • WO 1995/27138 A1 discloses a compressor with a pump rotor of an inverted frustoconical shape having a lower nozzle immersed in the oil sump.
  • the document DE 10 2007 038443 discloses a hermetic compressor which motor rotor comprises a ring element into which the bearing enters and to which the crankshaft is attached. The lower portion providing a tapered shape. To the outer circumferential surface being attached the permanent magnets of the electric motor.
  • Fig. 1 shows a hermetically sealed compressor (3') which is known from the prior art.
  • This prior art compressor (3') comprises a cylinder housing (4') which has a main bearing (5'), a crankshaft (6') which is journalled into the main bearing (5'), a sump (7') which contains lubricant, and a lubricant pick-up tube (7a') which is partly immersed into the lubricant sump (7').
  • the prior art compressor (3') further comprises an electric motor (2') which is arranged below the cylinder housing (4').
  • the prior art electric motor (2') comprises a rotor (1') and a matching stator (10') which respectively have the heights H1'.
  • the rotor (1') comprises a core (8') which has a central through hole (9') for concentrically receiving the crankshaft (6').
  • the stator (10') comprises a core (11'), a winding (12'), and a central opening (13') for concentrically receiving the rotor core (8').
  • the rotor core (8') comprises an outer diameter portion (14) with a height H1' which is concentrically arranged into the opening (13') of the stator core (11'), and an inner diameter portion (15') with a height H2' which is press-fitted onto the crankshaft (6).
  • a problem with the prior art compressor (3') is that the stable operation of the crankshaft (6') is jeopardized with increasing size and power of the electric motor (2'). Therefore, in the hermetically sealed compressor (3') it is generally desired to increase the height B' of the main bearing (5') so as to safeguard the stable operation of the crankshaft (6'). If the height B' of the main bearing (5') is increased in the upward direction, the overall height of the compressor (3') must also be increased. This would impede the lubrication performance. Moreover, this is not desired in view of the increasing transportation costs and the drop in the utilizable volume of the refrigeration appliance.
  • An objective of the present invention is to provide a rotor for use in an electric motor of a hermetically sealed compressor, and a refrigeration appliance having the same which overcomes the aforementioned drawbacks of the prior art in a cost effective way and which enables a reliable assembly of the rotor and a reliable operation of the crankshaft.
  • the rotor of the present invention comprises an extending portion which extends downwardly from the lower surface of the outer diameter portion.
  • the extending portion has a tapered shape. At least a part of the through hole within the extending portion is defined by the inner diameter portion which is to be press fitted onto the crankshaft.
  • the fixation of the rotor to the crankshaft has been improved.
  • an electric motor with a comparatively smaller or a comparatively larger size can be reliably installed into the compressor.
  • a power-to-size ratio of the hermetically sealed compressor has also been improved.
  • the rotor of the present invention it becomes also possible to utilize a comparatively longer main bearing without the need of increasing the overall height of the compressor.
  • a hermetically sealed compressor has been provided which can be reliably operated even at comparatively high refrigeration capacities involving comparatively large sized electric motors and high rotational speeds. Thereby, a consumer satisfaction can be increased.
  • the rotor core comprises an inner tubular portion for picking up lubricant from the lubricant sump. At least a part of the through hole within the extending portion is defined by the inner tubular portion.
  • the rotor core also serves as a lubricating device. Thereby, the need for installing a separate lubricant pick-up tube has been obviated.
