Definitions

  • the present invention relates to scroll compressors that reduce the amount of refrigerating machine oil discharged to the outside of a hermetic container.
  • a forced oil supply passage ( 18 ) which communicates with the oil supply pump ( 8 ) is disposed to supply oil to the bearing ( 15 ) and a spiral groove ( 19 ) is formed on the outer peripheral surface of a rotor ( 31 ) of the motor ( 3 ) to downwardly return the oil supplied to the bearing ( 15 ) in a forcible manner such that the oil after lubrication can be returned to the oil supply pump without using a special oil separator while the oil is forcibly supplied to the bearing ( 15 ) disposed on the upper side.
  • Patent Literature 1 Japanese Unexamined Patent Application Publication No. 5-302581 (for example, see FIG. 1)
  • the fixed cup is not rotated even during driving period of the electric motor since the fixed cup is disposed on the upper end of the sub-frame which is fixed to the hermetic container. Further, the balance weight is surrounded by the fixed cup.
  • FIG. 1 is a vertical cross-sectional view of a scroll compressor according to Embodiment 1 of the present invention.
  • the motor rotor 5 a is disposed inside the motor stator 5 b , and the penetrating flow passage 5 f is formed in the motor rotor 5 a in the axis direction.
  • the motor stator 5 b is disposed outside the motor rotor 5 a , and a motor stator coil 5 c is wound around the motor stator 5 b .
  • a main shaft portion 6 b of the main shaft 6 is fixedly provided inside the motor rotor 5 a .
  • the motor rotor 5 a rotates to cause the main shaft 6 to rotate and transmits a drive force to the compression mechanism 14 which is connected via the main shaft 6 .
  • second notches 5 g are formed between the outer periphery of the motor stator 5 b and the hermetic container 10 to serve as passages for a mixed gas of the refrigerant and the refrigerating machine oil.
  • An upper balance weight 15 a and a lower balance weight 15 b is fixed to the upper end face and the lower end face of the motor rotor 5 a , respectively, and in addition to the main shaft balance weight 6 f , those balance weights disposed at three positions keep the static balance and the dynamic balance. That is, those balance weights keep balance during shut down period of the electric motor 5 and offset the imbalance between the centrifugal force and the moment generated at the compression mechanism 14 during driving period of the electric motor 5 to keep balance. Further, an upper cup 17 is disposed to surround the upper balance weight 15 a at the upper end of the motor rotor 5 a , and a fixed cup 18 is disposed to surround the lower balance weight 15 b at the upper end of the sub-frame 8 .
  • the fixed cup 18 is formed to separate a cup inside space 18 e which contains the lower balance weight 15 b therein and a cup outside space 18 f which does not contain the lower balance weight 15 b therein (which is located outside the fixed cup 18 ) in the space between the upper end of the sub-frame 8 and the lower balance weight 15 b . Further, as shown in FIG. 2 , a gap space 18 d is formed between the upper end of the fixed cup 18 and the lower end of the motor rotor 5 a.
  • the outer peripheral surface of the motor stator 5 b is fixed to the hermetic container 10 by shrink-fitting, welding or the like, and the second notches 5 g are formed on the outer periphery to serve as passages for a mixed gas of the refrigerant and the refrigerating machine oil.
  • glass terminals 10 a are disposed on the side face of the hermetic container 10 , and the lead wires 5 h which extend from the motor stator 5 b are connected to the glass terminals 10 a.
  • the separated refrigerant gas flows through the gap space 18 d between the upper end of the fixed cup 18 and the lower end of the motor rotor 5 a and the penetrating flow passage 5 f of the motor rotor 5 a and is released to the outside of the hermetic container 10 through the discharge pipe 12 .
  • the fixed cup 18 is formed of two parts in the scroll compressor.
  • the fixed cup 18 is composed of a seat member 18 b for fixing to the sub-frame 8 and a cup member 18 a that surrounds the lower balance weight 15 b , and the cup member 18 a is connected to the seat member 18 b via a connection section 18 c.
  • the seat member 18 b can be formed thick to retain the fixture strength and the cup member 18 a can be formed thin to save material cost.
  • Embodiment 4 the scroll compressor according to Embodiment 4 will be described.
  • the seat member 18 b and the cup member 18 a are welded in the scroll compressor.
  • the cup member 18 a is connected to the seat member 18 b by welding at a connection section 18 c.
  • the seat member 18 b and the cup member 18 a are connected by welding in the fixed cup 18 , it is possible to prevent the cup member 18 a from being detached from the seat member 18 b due to pressure difference between the sup inside space 18 e and the cup outside space 18 f.
  • Embodiment 5 dimensions between the motor rotor 5 a and the fixed cup 18 in the scroll compressor are defined.
  • FIG. 7 is a view which shows a relationship of a vertical cross-sectional area of the gap space of the scroll compressor and a circulation amount of the refrigerating machine oil according to Embodiment 5 of the present invention.
  • the horizontal axis represents the vertical cross-sectional area of the gap space 18 d
  • the vertical axis represents the circulation amount of the refrigerating machine oil in the refrigeration cycle during operating period of the scroll compressor.
  • the dotted line represents the position of the vertical cross-sectional area of the penetrating flow passage 5 f of the motor rotor 5 a in FIG. 7 .
