たらす。The orbiting scroll has a thinly wound wrap 16 on a plywood (mirror plate) la, and has a rotation prevention mechanism 1c on the back surface for preventing rotation, and an orbiting bearing 1d into which the crank portion of the crankshaft is inserted. Fixed scroll 2 is also made of plywood (mirror plate)
A thinly wound wrap 2b is provided on 2a. Further, the fixed scroll is provided with an intake port 2C and a discharge port 2d. The fixed scroll and the orbiting scroll are combined with each other with their laps facing inward. The frame 4 is provided with a notch 4a S having a space in which the end plate 1a of the orbiting scroll can perform an orbiting motion. . The frame forms a back pressure chamber 4b for the back pressure of the orbiting scroll. The back pressure chamber is communicated with a compression chamber formed by the orbiting scroll, the wrap of the fixed scroll, and the end plate through a pressure equalizing hole (not shown) provided in the end plate of the orbiting scroll. The frame is further provided with a bearing 4c that supports the crankshaft and a pedestal 1d that supports the motor. An oil supply hole 3a is provided in the crankshaft 3, and oil from the lower part of the sealed container is supplied to the swing bearing 1a and the bearing 4c. Due to the rotation of the motor, the crankshaft and the anti-rotation mechanism perform a relative rotational movement, and as the space (EE contraction chamber) formed by the wraps of both scrolls and the end plate moves to the center, its volume decreases. As a result, the gas inhaled from the suction port is compressed and discharged from the discharge port. From the discharge port, the discharged gas passes through the airtight container and enters the discharge pipe 6a.
It gets spit out. When the scroll performs a compression action, a force acts to separate the scrolls. To prevent the scroll from separating, the pressure in the back pressure chamber on the back of the orbiting scroll is set to an intermediate pressure higher than the suction pressure and lower than the discharge pressure, thereby pressing the orbiting scroll against the fixed scroll. Oil supplied from the oil supply hole 3a of the crankshaft 3 to the swing bearing 1d and the bearing 4C flows to the back pressure chamber 4b where the pressure is low. The oil flowing into the back pressure chamber 4b fills the orbiting scroll,
Stirring loss occurs due to balance weight 4C. Further, when oil enters the notch 4a of the frame, the oil is compressed by the outer circumference of the end plate of the orbiting scroll, resulting in an increase in human labor.

〔発明の目的〕[Purpose of the invention]

本発明は上記の点に鑑みて旋回スクロールの鏡板外周部

を目的とするものである。In view of the above points, the present invention aims to remove oil from the outer periphery of the orbiting scroll in order to prevent oil compression on the outer periphery of the end plate of the orbiting scroll.

ことに着目したものである。The oil on the outer periphery of the end plate of the orbiting scroll is compressed where the outer periphery of the end plate of the orbiting scroll is close to the notch in the frame because the orbiting scroll orbits within the notch in the frame. This oil compression can be prevented by discharging the oil at the outer periphery of the rotation to the low-pressure part, but the volumetric efficiency will decline. The present invention focuses on the fact that if the oil on the outer periphery of the end plate of the orbiting scroll is easily moved into the notch of the frame or into the back pressure chamber, compression can be prevented and manpower can be reduced.

Since the overall structure and operation of the compressor are the same as those of the conventional compressor, their explanation will be omitted. FIGS. 2 and 3 show circumferential grooves 7 on the surface of the notch 4a of the frame 4 facing the back surface of the end plate 1a of the orbiting scroll 1.
This is an example of a structure having a. As shown in FIG. 3, even when the end plate 1a of the orbiting scroll is close to the frame 4, oil can move through the groove 7a, so oil compression can be prevented. This circumferential groove may be provided in an intermittent groove 7b as in the example shown in FIGS. 4 and 5. 6 and 7 show an example of a structure in which a circumferential groove 8 is provided on the surface of the notch 4a of the frame 4 facing the outer peripheral portion of the end plate 1a of the orbiting scroll 1. As shown in FIG. 6, even if the end plate 1a of the orbiting scroll approaches the frame, oil can move through the grooves 8, so oil compression can be prevented. In this method, as shown in FIG. 8, a similar effect can be obtained by providing a circumferential groove 9 on the back side of the end plate 1a of the orbiting scroll 1.

As shown in FIG. 10, when the end plate 1a of the orbiting scroll approaches the frame 4, oil flows into the groove 10.
Since the oil can be moved through the back pressure chamber 4b, it is possible to prevent oil FE from condensing.

This structure is a combination of the examples shown in FIGS. 9, 9, and 10. A circumferential groove 8 is provided on the surface of the notch 4a of the frame that faces the outer periphery of the end plate 1a of the orbiting scroll, and a circumferential groove 7 and a radial groove 10 are provided on the surface that faces the back surface of the end plate 1a of the orbiting scroll. have FIGS. 13 and 14 show an example of a structure in which a radial groove 11 is provided on the back surface of the end plate 1a of the orbiting scroll 1 to communicate the outer peripheral part of the end plate and the back pressure chamber 4b. With this structure, the same effects as the examples shown in FIGS. 9 and 10 can be obtained. These structures allow the oil on the outer periphery of the end plate of the orbiting scroll to move easily, thereby reducing loss due to oil compression. FIG. 15 shows an embodiment in which a suction chamber is used as a low pressure section and oil around the outer periphery of the rotating mirror plate is returned to the suction chamber via a fixed scroll. The fixed scroll is provided with an oil drain passage 20 that opens on one side to the notch 4a of the frame 4 and on the other side to the suction chamber. Oil on the outer periphery of the end plate of the orbiting scroll is discharged from this oil drain passage to the suction chamber. Therefore, oil compression due to the outer periphery of the orbiting scroll end plate can be prevented, and input power can be reduced. When the suction chamber is used as a low pressure section, the gap 22 between the orbiting scroll end plate and the back of the frame cutout is narrowed. If a means for improving the sealing performance between the back pressure chamber 4b and the outer peripheral part of the end plate of the orbiting scroll is also used, such as providing a labyrinth 21, it is possible to prevent a decrease in the volumetric movement due to excessive oil discharge into the suction chamber, which is even more effective. be. 1st
Figure 6 shows an embodiment in which the oil drain passage is provided in the end plate of the orbiting scroll. The action and effect are the same as in Fig. 15, but
The structure of the oil drain passage becomes simple. In the case where the oil drain passage is provided in the end plate of the orbiting scroll, a structure in which the oil drain passage is provided in the face corresponding to the notch in the frame at the back surface of the end plate of the orbiting scroll as shown in FIG. 19 is also considered. A feature of this structure is that when the orbiting scroll separates from the fixed scroll and the back surface of the end plate of the orbiting scroll comes into contact with the notch in the frame, the oil drainage passage is closed and oil drainage can be stopped. FIG. 17 shows an embodiment in which a compression chamber in the middle of compression is used as a low pressure section and an oil drain passage is provided in a fixed scroll. In the space formed by the fixed scroll and orbiting scroll wraps and end plates, an oil drainage passage is opened in the middle of compression. A feature of this method is that it can prevent a decrease in volumetric efficiency because the oil is drained into the middle of the wire. FIG. 18 shows an embodiment of a structure in which an oil drain passage is provided in the end plate of the orbiting scroll to drain oil into the compression chamber. With the structure described above, oil on the outer periphery of the end plate of the orbiting scroll can be discharged, and an increase in input due to oil compression can be prevented.

〔発明の効果〕〔Effect of the invention〕

本発明は上記の如く構成したので、鏡板外周部の油圧縮
を防止し、入力を低減できる。Since the present invention is configured as described above, it is possible to prevent oil compression on the outer peripheral portion of the head plate and reduce input power.
