As disclosed in Japanese Patent No. 2796, a mixed gas of a refrigerant gas and a lubricating oil compressed by a scroll compression mechanism section is discharged into an upper space above the compression mechanism section from a discharge hole provided in an upper portion of a fixed scroll, By colliding with the inner wall of the closed container, the refrigerant gas and the lubricating oil are separated. A plurality of passages having different passage resistances are provided on the outer periphery of the frame. Since the lubricating oil has a high viscosity, it passes through a passage having a small passage resistance. On the other hand, the refrigerant gas has a low viscosity and thus passes through a passage having a large passage resistance. In this way, the refrigerant gas and the lubricating oil respectively flow into the middle space between the compression mechanism portion and the drive motor portion. The refrigerant gas passes through the cut portion provided on the outer periphery of the drive motor and flows into the lower space below the drive motor,
The driving electric motor is cooled, and then again flows into the middle space through the cut portion on the outer periphery of the driving electric motor. On the other hand, the lubricating oil flows into the oil sump from the middle space through the cut portion on the outer periphery of the driving electric motor.

ガスと潤滑油が混合状態で密閉容器外へ流出するため油
上がりが増大する。In the above prior art, since the refrigerant gas flowing from the lower space into the middle space blows up the lubricating oil flowing from the upper space into the middle space, the refrigerant gas and the lubricating oil are mixed. Since the oil flows out of the closed container, the oil rise increases.

低下する。In order to prevent the lubricating oil from blowing up due to the refrigerant gas, the cross-sectional area of the passages on the outer circumference of the frame or the number of passages is changed to reduce the speed of the refrigerant gas flowing in the lower space to reduce the blowing up of the lubricating oil. However, since the flow rate of the refrigerant gas flowing through the lower space is reduced by doing so, the cooling effect of the drive motor is reduced.

入した冷媒ガスは吐出管より密閉容器の外に流出する。The refrigerant gas sucked from the suction pipe is compressed by the orbiting action of the fixed scroll and the orbiting scroll, and is discharged from the discharge hole to the upper space while being mixed with the refrigerant gas. The mixed gas of the refrigerant gas and the oil flows from the upper space above the compression mechanism portion into the lower space below the drive motor through the guide passage. Since the lower space has a larger cross-sectional area than the guide passage, the velocity of the mixed gas becomes slow. When the speed of the mixed gas becomes slow, the lubricating oil contained in the mixed gas is separated by its own weight and drops into the oil sump. On the other hand, the refrigerant gas cools the driving electric motor and flows through the cut portion of the driving electric motor and the gap between the rotor and the stator of the driving electric motor to the middle space between the compression mechanism portion and the driving electric motor portion. The refrigerant gas flowing into the central space flows out of the closed container through the discharge pipe.

ガスは吐出管25より密閉容器1の外に流出する。Next, the operation will be described. When the orbiting scroll 6 orbits through the crankshaft 9 by the drive motor 3, the refrigerant gas sucked from the suction pipe 24 is compressed by the orbiting action of the fixed scroll 5 and the orbiting scroll 6. On the other hand, the lubricating oil passes through the oil supply passage 13 from the oil supply device 14, and the main bearing 10, the lower bearing 11, and the slewing bearing 12
Is lubricated, then flows into the compression chamber via the intermediate pressure chamber 17, and is discharged from the discharge hole 15 to the upper space 16 in a state of being mixed with the refrigerant gas. The mixed gas of the discharged refrigerant gas and oil flows into the lower space 22 from the upper space 16 through the guide passage 21. Since the lower space 22 has a larger cross-sectional area than the guide passage 21, the velocity of the mixed gas becomes slow. When the speed of the mixed gas becomes slow, the lubricating oil contained in the mixed gas is separated by its own weight and falls into the oil sump 4. On the other hand, the refrigerant gas cools the driving electric motor 3, and the cutting portion 2 of the driving electric motor 3
0 and flows through the gap between the rotor and the stator of the drive motor 3 into the middle space 23. The refrigerant gas flowing into the middle space 23 flows out of the closed container 1 through the discharge pipe 25.

め、油上がりの少ない圧縮機を提供することができる。Since the lubricating oil is separated from the mixed gas of the refrigerant gas and the lubricating oil in this way, the mixed gas in the upper space 16 containing a large amount of lubricating oil directly flows out of the closed container through the discharge pipe 25. Instead, the lubricating oil is separated in the lower space 22 and then flows out of the closed container 1 through the middle space 23. Therefore, it is possible to provide a compressor in which oil does not rise.

Therefore, the cooling effect of the drive motor 3 is very high.

果は非常に高くなる。Next, another embodiment will be described with reference to FIGS. FIG. 2 shows a partial cross-sectional view of a hermetic scroll compressor embodying the present invention, and FIG. 3 shows a view taken along the line II in FIG. In the present embodiment, the cut portion 20 provided on the outer peripheral portion of the driving electric motor 3 in the example of FIG. Similar to the example of FIG. 1, the cut portion 20 has a structure that forms a guide passage 21 together with the frame groove 18, the guide plate 19 and the inner wall of the closed container. Similar to the example of FIG. 1, the mixed gas of the refrigerant gas and the oil discharged into the upper space 16 flows into the lower space 22 from the upper space 16 through the guide passage 21, and the lubricating oil contained in the mixed gas in the lower space 22. Are separated by their own weight and fall into the oil sump 4. On the other hand, the refrigerant gas cools the drive motor 3 and flows into the middle space 23 through the gap between the rotor and the stator of the drive motor 3. The refrigerant gas flowing into the middle space 23 is discharged from the discharge pipe 25 into the closed container 1.
Spills out of. As described above, all the refrigerant gas passes through the gap between the rotor and the stator of the drive motor 3 and the intermediate space 23.
Therefore, the high-speed mixed gas flowing from the upper space 16 through the guide passage 21 into the lower space 22 does not separate the lubricating oil, and the cut portion 20 facing the cut portion 20 forming the guide passage 21. Further, since the phenomenon of flowing into the middle space 23 and flowing out of the closed container 1 through the discharge pipe 25 does not occur, oil rise can be reduced. Further, since all the refrigerant gas flows into the middle space 23 through the gap between the rotor and the stator of the driving electric motor 3, the cooling effect of the driving electric motor 3 becomes very high.

The driving electric motor 3 having the cut portion 20 can also provide the same effects as those in the examples of FIGS. 2 and 3.

The present embodiment has a structure in which fins 27 are provided below the rotor of the drive motor 3 in addition to the example of FIG. Similar to the example of FIG. 1, the mixed gas of the refrigerant gas and the oil discharged into the upper space 16 flows into the lower space 22 from the upper space 16 through the guide passage 21. The mixed gas flowing into the lower space 22 is fed to the fins provided under the rotor of the driving motor 3 by 27
Lubricating oil that causes more rotational motion and has a large mass adheres to the coil portion of the driving electric motor 3 stator and the inner wall of the closed container due to centrifugal force. The lubricating oil adhering to the coil drips into the oil sump 4 due to its own weight, and the lubricating oil adhering to the inner wall of the closed container travels along the inner wall of the closed container and flows into the oil sump 4. On the other hand, the refrigerant gas cools the driving electric motor 3 similarly to the example of FIG. 1, flows through the cut portion 20 of the driving electric motor 3 and the gap between the rotor and the stator of the driving electric motor 3 into the middle space 23, and the discharge pipe From 25, it flows out of the closed container 1. In this way, it is possible to provide a compressor with less oil spillage.
