The sealed container 2 has an oil reservoir 6 at the bottom, a container body 4 that houses the electric element 20 and the scroll compression element 10, and a bowl-shaped end cap 4A that is attached to close the upper opening of the container body 4. , And a bowl-shaped bottom 4B attached so as to close the bottom opening of the container body 4.

  An upper support frame 28 is provided in the hermetic container 2, and the upper support frame 28 divides the hermetic container 2 into a discharge chamber 42 and an electric element chamber 43. The discharge chamber 42 is formed on the end cap 4A side (upper side) of the upper support frame 28, and the electric element chamber 43 is formed on the bottom 4B side (lower side) of the upper support frame 28. Specifically, the discharge chamber 42 is formed between the scroll compression element 10 and the end cap 4A.

In a state where the fixed scroll 12 and the swing scroll 14 are engaged with each other, a compression space 16 (compression chamber) is formed in a sealed space formed between the fixed scroll 12 and the swing scroll 14. The fixed scroll 12 is composed of a disc-shaped end plate 12A and a wrap 12B that is upright and formed in an involute curve or an approximate curve thereof, and has a discharge port 17 at the center and a suction port at the outer periphery. 18 is provided.

  A suction pipe 51 is connected to the suction port 18 from the vertical direction through the end cap 4A of the sealed container 2. Further, the inside of the discharge chamber 42 through which the discharge port 17 communicates is configured between the scroll compression element 10 (the fixed scroll 12 and the swing scroll 14) and the inner surface of the sealed container 2 (the inner surfaces of the end cap 4A and the container body 4). The electric element chamber 43 communicates with the communication passage 34 (gas path P).

  The orbiting scroll 14 is formed in a disc-shaped end plate 14A, and a wrap 14B that stands upright and is formed in the same shape as the wrap 12B of the fixed scroll 12, and is projected on the opposite surface of the end plate 14A of the end plate 14A. , And a boss 29 having a boss hole at the center. A bearing portion 30 that continuously extends downward is formed in the central portion of the upper support frame 28, and the upper portion of the rotating shaft 22 is supported on the bearing portion 30.

  An oil pump 76 is provided below the rotary shaft 22. The oil pump 76 sucks up oil accumulated in the oil reservoir 6 formed in the inner bottom portion (bottom 4B) of the sealed container 2 by the rotation of the rotary shaft 22, and scrolls through an oil passage 22C formed in the rotary shaft 22. The compressor 1 is supplied to sliding portions (between the rotary shaft 22 and the bearing portion 30, between an eccentric shaft 22A and a boss 29 described later, between the swing scroll 14 and the upper support frame 28, etc.).

  The electric element 20 includes a stator 23 provided with a coil and fixed (for example, shrink-fitted) to the inner surface of the container body 4 of the sealed container 2, and a rotor 25 containing a magnet that rotates in the stator 23. The rotary shaft 22 is fitted in the center of the rotor 25. The lower part of the rotary shaft 22 (the bottom 4B side of the rotor 25) is pivotally supported by a support boss 60 provided at the center of the lower support frame 52 serving as a sub bearing. The lower support frame 52 is also fixed to the container body 4 of the sealed container 2 by welding (not shown) below the electric element 20.

  An eccentric shaft (pin) 22A is provided at the top end of the rotating shaft 22 constituting the electric element 20 so that the axis of the rotating shaft 22 is shifted from the axis of the predetermined dimension. It is rotatably inserted into the boss hole of the boss 29 of the scroll 14. The fixed scroll 12 is fixed to the upper support frame 28 by a plurality of bolts 78 (only one is shown in the drawing), and the orbiting scroll 14 is moved upward by an Oldham ring 41 and an Oldham mechanism 40 comprising an Oldham key. It is supported on the support frame 28. Thereby, the orbiting scroll 14 is configured to perform a turning motion without rotating with respect to the fixed scroll 12.

Revolve on a circular path so as not to rotate with respect to the fixed scroll 12. Then, by the revolution, the fixed scroll 12 and the swing scroll 14 gradually reduce the plurality of crescent-shaped compression spaces 16 formed between the wrap 12B and the wrap 14B from the outside toward the inside. As a result, the refrigerant gas is sucked into the compression space 16 from the suction pipe 51. The sucked refrigerant gas is gradually compressed from the outside toward the inside through the compression space 16 to become high-pressure gas, and is discharged from the discharge port 17 to the discharge chamber 42.

  On the other hand, the stator 23 constituting the electric element 20 is fixed to the inner surface of the sealed container 2 (container body 4), and a predetermined gap 23A (space) between the inner surface of the container body 4 and the peripheral portion of the stator 23. Is configured. The gaps 23 </ b> A are formed at substantially equal intervals around the stator 23, and the periphery of the stator 23 other than the gap 23 </ b> A is fixed to the inner surface of the container body 4. The electric element chamber 43 communicates with the lower oil reservoir 6 via a gap 23 </ b> A (passage) between the stator 23 and the inner surface of the sealed container 2. This gap is formed to have a size approximately equal to a communication portion 66 (described later) formed by a notch portion 64A provided in the partition plate portion 64 of the lower support frame 52 and the inside of the sealed container 2.

  A shielding plate 54 is provided on the lower surface of the upper support frame 28 so as to extend from the upper support frame 28 toward the electric element 20 and surround the periphery of the bearing portion 30. It is made of an insulating material such as Lumira (trade name), and is provided outside the bearing portion 30 with a predetermined distance. Specifically, the shielding plate 54 is the same as the region corresponding to the upper side of the rotor 25 on the inner side of the coil end 24 of the stator 23, or corresponds to the outer side of the region (see FIG. 1).

  The upper part of the shielding plate 54 is fixed to the lower surface of the upper support frame 28, and the lower end of the shielding plate 54 extends below the upper surface of the coil end 24 of the stator 23 that is the upper end of the electric element 20 (implemented). In the example, it extends to a substantially intermediate position between the upper surface of the rotor 25 and the upper surface of the coil end 24 of the stator 23). Incidentally, B is a balancer attached to the upper surface of the rotor 25 and is located inside the shielding plate 54. The closed container 2 is provided with a plurality of support legs 70 (two are shown in FIG. 1) for standing the closed container 2 upright.

  On the other hand, the lower support frame 52 is formed in a disc shape as shown in FIGS. 2 and 3 and extends in a radial direction from a support boss 60 that supports the rotary shaft 22 and has a predetermined thickness and a predetermined width. A formed fixing part 62 is provided. The fixing portions 62 are provided at substantially equal intervals in the four directions around the support boss 60. A partition plate portion 64 is formed between the fixed portions 62. The partition plate portion 64 is formed in a plate shape thinner than the fixed portion 62 and is integrally formed with each fixed portion 62.

  That is, each fixing portion 62 is formed so as to protrude by a predetermined dimension in the thickness direction of the partition plate portion 64 (the vertical direction in FIG. 3), and thereby the lower support frame 52 ensures a predetermined strength. The lower support frame 52 has an outer shape (around each fixed portion 62 and partition plate portion 64) that is substantially the same size as the inner surface of the hermetic container 2, and the periphery of the support frame 28 is the inner surface of the hermetic container 2. As described above, each fixing portion 62 is welded and fixed to the container body 4 of the sealed container 2 (not shown).

  Thereby, the inside of the sealed container 2 is partitioned by the lower support frame 52 into a space including the oil reservoir 6 and a space above it. Specifically, the lower part of the electric element 20 is used as a reference (the lower support frame 52 is used as a reference), and the electric element chamber 43 is partitioned upward and downward (in the direction of the oil reservoir 6). The lower support frame 52 serves as partitioning means of the present invention that partitions the space in the sealed container 2 (in the electric element chamber 43) into a space including the oil reservoir 6 and a space above the space.

  Further, the partition plate portion 64 is provided with four notches 64A through which oil that lubricates the sliding portion of the scroll compressor 1 and oil separated from the refrigerant gas can pass, and the notches 64A The partition plate 64 is cut out from the outer peripheral edge side toward the center. As shown in FIG. 4, the notch portion 64A is provided approximately in the middle between the fixed portion 62 and the fixed portion 62, and is cut in a predetermined dimension toward the center direction in parallel with a tangent line contacting the circumference of the lower support frame 52. It is missing. A gap formed between the cutout 64A and the inside of the sealed container 2 is defined as a communication portion 66 of the present invention, and the electric element chamber 43 is communicated with the upper side and the lower side of the lower support frame 52 through the communication portion 66. (Shown in FIG. 1). The size of the communication part 66 will be described later.

  Here, the high-temperature and high-pressure refrigerant gas compressed and discharged by the scroll compression element 10 is discharged into the discharge chamber 42 and is discharged into the electric element chamber 43 through the communication path 34, so that the inside of the sealed container 2. Becomes high pressure. The electric element chamber 43 is partitioned by a lower support frame 52, and an oil reservoir 6 is provided therebelow. Then, the oil in the oil reservoir 6 is pumped up by the oil pump 76, so that the oil reservoir 6 has a lower pressure (negative pressure) than the electric element chamber 43 on the lower support frame 52.

  That is, the combined size of the communicating portions 66 is that the oil stored in the oil reservoir 6 is pumped up by the oil pump 76, so that the interior of the electric element chamber 43 (oil reservoir 6) below the lower support frame 52 is increased. In addition, it is formed so as to have a negative pressure in the electric element chamber 43 on the lower support frame 52. Specifically, the combined size of each communication portion 66 is such that when the oil in the oil reservoir 6 is pumped up by the oil pump 76 and becomes negative pressure, the oil accumulated on the lower support frame 52 is discharged from each communication portion 66. It is formed in a size that can be sucked into the oil reservoir 6.

  On the other hand, the discharge pipe 50 of the scroll compressor 1 is connected to the inlet side of an external condenser (not shown), and the suction pipe 51 is connected to the outlet side of an external evaporator (not shown). The scroll compressor 1, the condenser, a decompression device (not shown), and the evaporator constitute a known refrigerant circuit. A predetermined amount of refrigerant gas is enclosed in the refrigerant circuit. Then, the refrigerant gas discharged from the discharge port 17 of the scroll compression element 10 reaches the electric element chamber 43 through the discharge chamber 42 and the communication path 34, exits the electric element chamber 43, and is discharged from the discharge pipe 50. The circulation that sequentially flows into the condenser, the pressure reducing device, and the evaporator and returns to the suction port 18 of the scroll compression element 10 from the suction pipe 51 is repeated.

  Next, an outline of the flow of refrigerant gas and oil in the scroll compressor 1 will be described. When the stator 23 (coil) of the electric element 20 is energized and the rotor 25 is activated and the rotary shaft 22 rotates, the swing scroll 14 is revolved as described above. The refrigerant gas introduced from the suction pipe 51 to the suction port 18 is compressed in the compression space 16 of the scroll compression element 10, and then discharged from the discharge port 17 to the discharge chamber 42 and discharged into the electric element chamber 43. Is done.

  Then, the refrigerant gas discharged into the electric element chamber 43 is separated in oil by the flow velocity being reduced there, and accumulated on the electric element 20, and the oil accumulated on the electric element 20 is centrifuged by the rotor 25. It moves to the inside of the sealed container 2 around the stator 23 by force. At this time, since the oil stored in the oil reservoir 6 is pumped up by the oil pump 76, the oil reservoir 6 on the lower side of the lower support frame 52 is more negative than the pressure on the upper side of the lower support frame 52. become.

  As a result, the oil accumulated inside the sealed container 2 around the stator 23 due to the centrifugal force of the rotor 25 enters the oil reservoir 6 from each communication portion 66 and the gap 23A between the stator 23 and the inner surface of the sealed container 2. Aspirated and stored. The oil stored in the oil reservoir 6 is supplied again to the sliding portion of the scroll compressor 1 as described above by the oil pump 76. The refrigerant gas from which the oil is separated by flowing into the gas path P between the inside of the sealed container 2 and the shielding plate 54 is discharged from the discharge pipe 50 to the outside of the scroll compressor 1 (outside of the sealed container 2). Is done.

  As described above, the lower support frame 52 that partitions the inside of the sealed container 2 into a space including the oil reservoir 6 and a space above it is provided, and the upper and lower surfaces of the lower support frame 52 are communicated with the lower support frame 52. Since the communication portion 66 is provided, the oil pump 76 supplies oil to the sliding portions of the scroll compressor 1 so that a negative pressure is generated in the sealed container 2 (the space including the oil reservoir 6) below the lower support frame 52. Can be. As a result, oil accumulated on the electric element 20 (oil accumulated inside the sealed container 2 around the stator 23) can be sucked into the lower oil reservoir 6 from the communicating portion 66 of the lower support frame 52.

  Further, the oil guided to the electric element 20 side from the communication path 34 and rotated on the electric element 20 by the rotation of the electric element 20 can be smoothly collected in the lower oil reservoir 6. The amount can be reduced. In particular, since the partitioning means is constituted by the lower support frame 52, the number of parts can be reduced.

  In the embodiment, the cutout portion 64A is cut out by a predetermined dimension in parallel with the tangent line that contacts the circumference of the lower support frame 52. However, the cutout section 64A is not limited to be parallel to the tangent line that touches the circumference of the lower support frame 52. If the inside of the sealed container 2 below the frame 52 can be made negative pressure and the oil on the upper side of the lower support frame 52 can be smoothly collected in the oil reservoir 6, a round hole is formed in the lower support frame 52 (partition plate portion 64). You can open a square hole, an elliptical hole, etc. Further, if the inside of the sealed container 2 below the lower support frame 52 can be set to a negative pressure, and the oil on the upper side of the lower support frame 52 can be smoothly collected in the oil reservoir 6, the tangent line that contacts the circumference of the lower support frame 52 It may be recessed into a shape such as a rectangle, semi-circle, or ellipse from the center to the center. Thereby, the effect similar to an Example can be acquired.

  Further, the partitioning means for partitioning the electric element chamber 43 up and down is configured by the lower support frame 52, but the partitioning means is not limited to the lower support frame 52, and a donut-shaped disk-shaped partition plate is provided on the upper surface of the stator 23. The partition plate may be provided as partition means. In this case, the partition plate is tightly fixed to the coil end 24, and the partition plate is provided with a notched communication portion similar to the communication portion 66 provided between the inner surface of the sealed container 2 and the lower support frame 52. The inside of the sealed container 2 can be partitioned into an upper part and a lower part of the electric element 20 by this partition plate. As a result, even when the gap 23A between the stator 23 and the inner surface of the hermetic container 2 is larger than the communication portion 66, if the oil accumulated in the oil reservoir 6 is pumped up by the oil pump, the lower side from the partition plate is made negative pressure. Therefore, the same effect as described above can be obtained.

  Further, the partitioning means is provided on the lower side of the electric element 20 (lower support frame 52) and on the upper side of the electric element 20 (the donut-shaped disk-shaped partition plate), the partitioning means includes a space including the oil reservoir 6, and If the lower part of the partition means can be made negative pressure when the oil stored in the oil reservoir 6 is pumped up by the oil pump, the electric element chamber 43 can be partitioned at any position in the vertical direction. There is no problem. However, at this time, it is necessary to provide a space of about 10% on the oil in a state where the oil is stored in the oil reservoir 6 at a position where the outlet of the communication passage 34 and the opening of the discharge pipe 50 are not blocked.

  Further, the partitioning means is constituted by a lower support frame 52 integrally formed with a plurality of fixing portions 62 fixed by welding to the container body 4 of the sealed container 2 and a partition plate portion 64 provided between the fixing portions 62. However, the partitioning means is not limited to the integrally formed lower support frame 52 of each fixing portion 62 and the partition plate portion 64, and the lower support frame 52 (each fixing portion 62) and the disc-shaped partition plate are separately provided. It does not matter if it is provided. As a result, if the disc-shaped partition plate is disposed on the upper side (the electric element 20 side) or the lower side of the conventional lower support frame, the conventionally used lower support frame can be used as it is. It is. It should be noted that the present invention is not limited only to the embodiments, and the present invention is effective even when various other changes are made without departing from the spirit of the present invention.
