Description

TECHNICAL FIELD

[0001] The utility model relates to scroll compressor field, especially, relate to a scroll compressor of inside lubrication improved scroll compressor mechanism. BACKGROUND

[0002] The content of this section only provides the background information related to the present disclosure, which may not constitute the prior art.

[0003] The scroll compressor includes a scroll compressor mechanism composed of a moving scroll and a fixed scroll, and a working cavity is defined inside the scroll compressor mechanism, and during the operation of the compressor, working fluid is sucked into the working cavity and compressed in the working cavity. The scroll compressor mechanism includes a suction area for sucking working fluid into the working cavity. The number of suction areas of the scroll compressor mechanism is usually two, and each suction area includes a suction port. In the scroll compressor mechanism of the related art, an oil outlet hole of a lubricating oil passage is provided at a position near the suction port of one of the two suction areas (i.e. the proximal suction area). During the operation of the compressor, the lubricating oil reaches the suction port through the oil outlet hole, and then enters the suction area of the scroll compressor mechanism with the working fluid and lubricates the suction area. In this scroll compressor mechanism, for example, because the distal suction area (i.e. the suction area far from the oil outlet hole) is far from the oil outlet hole, the lubricating oil discharged from the oil outlet hole is difficult to reach the distal suction area, and the distal suction area is only lubricated by a small amount of lubricating oil in the working fluid, so the distal suction area is usually not fully lubricated, resulting in severe wear of the fixed scroll part and the moving scroll part that contact each other at the distal suction area during the operation of the compressor.

[0004] Figure 1is a top view of a orbiting scroll of a scroll compressor mechanism of a scroll compressor of the related art. As shown in the figure, the orbiting scroll 100 of the scroll compressor mechanism of the scroll compressor comprises an orbiting scroll end plate 101 and orbiting scroll blades 102 extending vertically from the orbiting scroll end plate 101. A lubricating oil passage (not shown) is provided in the orbiting scroll end plate 101, which comprises an oil outlet hole 103 opening on the surface of the orbiting scroll end plate 101 for guiding the lubricating oil in the lubricating oil passage into the proximal suction area of the scroll compressor mechanism (in which the orbiting scroll blades and the fixed scroll blades can be intermittently engaged and disengaged to form working chambers and working fluid is sucked into the working chambers during the operation of the compressor, which is defined between the starting portion of the outer profile of the fixed scroll blades and the corresponding portion of the orbiting scroll blades 102), which is positioned in the circumferential direction substantially aligned with the starting end of the orbiting scroll blades 102 and on the inner side of the orbiting scroll blades 102 in the radial direction (i.e. the oil outlet hole 103 is located at the suction port of the proximal suction area). During the operation of the compressor, the lubricating oil in the lubricating oil passage reaches the suction port of the proximal suction area of the scroll compressor mechanism through the oil outlet hole 103, and then lubricates the proximal suction area as the working fluid enters the proximal suction area. The problem of this scroll compressor mechanism is that since the distal suction area of the scroll compressor mechanism (which is defined between the starting portion of the inner profile of the fixed scroll blades and the corresponding portion of the orbiting scroll blades, and is far away from the oil outlet hole) is far away from the oil outlet hole, the lubricating oil discharged from the oil outlet hole is difficult to reach the distal suction area, and the distal suction area is only lubricated by a small amount of lubricating oil in the working fluid, so the distal suction area is usually not fully lubricated, resulting in severe wear of the fixed scroll part and the orbiting scroll part contacting each other at the distal suction area during the operation of the compressor.

[0005] Therefore, there is a need for an improved scroll compressor mechanism with an improved lubrication structure to improve the lubrication of the distal suction area of the scroll compressor mechanism, thereby reducing the wear of the fixed scroll part and the orbiting scroll part contacting each other at the distal suction area.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the following detailed description of the present invention is for illustrative purposes only and is not intended to limit the present invention or its applications or uses. Furthermore, the same reference numerals are used to denote the same components in the accompanying drawings of the various embodiments.

[0031] This utility model provides a scroll compressor mechanism, which includes an improved lubrication structure. The lubrication structure includes an oil outlet hole disposed in the moving scroll end plate and an oil delivery groove disposed on the surface of the moving scroll end plate and communicating with the oil outlet hole. The oil delivery groove is used to directly guide the lubricating oil discharged from the oil outlet hole to the far-end intake area of ​​the scroll compressor mechanism to ensure that the far-end intake area is adequately lubricated.

[0032] The construction and working principle of the lubrication structure of the vortex compressor mechanism according to a preferred embodiment of the present invention are described in summary with reference to the various views in the accompanying drawings.

[0033] Figures 2-4 A vortex compression mechanism according to a first embodiment of the present invention is described. In the following text, reference will be made to... Figures 2-4 The overall structure and working principle of the lubrication structure of the scroll compression mechanism according to the first embodiment of the present invention are briefly described.

[0034] Figure 2 This is a longitudinal cross-sectional view of the moving scroll of the scroll compression mechanism according to the first embodiment of the present invention. As shown in the figure, the moving scroll 10 of the scroll compression mechanism includes a moving scroll end plate 11, in which a lubricating oil channel 12 is provided. The lubricating oil channel includes an oil inlet hole 13, a transverse hole 14 communicating with the oil inlet hole 13, a first oil outlet hole 15 (i.e., another oil outlet hole), and a second oil outlet hole 16 (i.e., an oil outlet hole), wherein both the first oil outlet hole 15 and the second oil outlet hole 16 are connected to the transverse hole 14. Both the first oil outlet hole 15 and the second oil outlet hole 16 are provided in the moving scroll end plate 11, and the first oil outlet hole 15 is located radially inside the second oil outlet hole 16. The oil inlet hole 13 of the lubricating oil channel 12 communicates with the inner space of the hub of the moving scroll 10, and the first oil outlet hole 15 and the second oil outlet hole 16 of the lubricating oil channel 12 open onto the surface 17 of the moving scroll end plate 11. The surface 17 of the moving scroll end plate 11 faces the working chamber of the scroll compressor mechanism, and the moving scroll blades extend from this surface. Lubricating oil entering the lubricating oil passage 12 from the oil inlet 13 can flow through the transverse hole 14 and then into the first oil outlet 15 and the second oil outlet 16, and flow through the first oil outlet 15 and the second oil outlet 16 to the surface 17 of the moving scroll end plate 11.

[0035] Figure 3This is a top view of the moving scroll of the scroll compressor mechanism according to the first embodiment of the present invention. The scroll compressor mechanism internally defines a working chamber and includes an intake region for drawing working fluid into the working chamber. This intake region includes a proximal intake region and a distal intake region, the specific definitions of which will be referred to below. Figure 4 Detailed Description. As shown in the figure, the moving scroll 10 of the scroll compressor mechanism includes a moving scroll blade 18 extending vertically from the surface 17 of the moving scroll end plate 11. The moving scroll blade 18 includes a starting end 182. This starting end 182 corresponds to the outer free end of the moving scroll blade, and at the starting end 182, the moving scroll blade and the fixed scroll blade can effectively contact each other to form a working cavity. The position of the starting end 182 of the moving scroll blade approximately corresponds to the position of the intake port in the near-end intake region. The first oil outlet 15 and the second oil outlet 16 of the lubricating oil passage 12 are both approximately aligned with the starting end 182 in the circumferential direction, and the first oil outlet 15 is located radially inside the moving scroll blade 18 in the near-end intake region, while the second oil outlet 16 is located radially outside the moving scroll blade 18 in the near-end intake region (see reference). Figure 4 The first oil outlet 15 and the second oil outlet 16 are aligned with each other in the circumferential direction. Therefore, only one transverse hole (i.e., the transverse hole 14 of the lubricating oil channel) extending in the radial direction needs to be drilled in the moving scroll end plate to supply lubricating oil to the first oil outlet 15 and the second oil outlet 16. An oil delivery groove 19 is provided on the surface 17 of the moving scroll end plate 11. The oil delivery groove 19 communicates with the second oil outlet 16 and extends from the second oil outlet 16 in a clockwise direction (the clockwise direction is...). Figure 3 The clockwise direction (and in this embodiment, this clockwise direction is also the direction of rotation of the moving vortex relative to the stationary vortex) extends to the distal intake region of the vortex compression mechanism (hereinafter referred to as...) Figure 4 (Detailed description).

[0036] Figure 4 This is a schematic top cross-sectional view of the scroll compression mechanism according to the first embodiment of the present invention, wherein a fixed scroll blade and a moving scroll blade are nested together. As shown, the moving scroll blade 18 of the moving scroll 10 and the fixed scroll blade 21 of the fixed scroll 20 mesh with each other to form a working cavity. The fixed scroll blade 21 includes an inner profile 214 and an outer profile 215, wherein the inner profile 214 corresponds to the portion of the inner wall surface of the fixed scroll blade 21 that can form a tight mesh with the moving scroll blade 18, and the outer profile 215 corresponds to the portion of the outer wall surface of the fixed scroll blade 21 that can form a tight mesh with the moving scroll blade 18. The starting end of the inner profile 214 is at... Figure 4 As shown in 213, the starting end of the outline 215 is at... Figure 4As shown in Figure 216, during compressor operation, working fluid can be drawn into the working chamber and compressed within it. The scroll compressor mechanism includes an intake region for drawing working fluid into the working chamber, and the intake region includes a proximal intake region 25 and a distal intake region 26. During compressor operation, at the proximal intake region 25, the moving scroll blades 18 and the stationary scroll blades 21 can intermittently engage and disengage to form the working chamber, and the working fluid is drawn into it. The proximal intake region 25 is defined between the starting portion 211 of the outer profile 215 of the fixed scroll blade 21 (the starting portion 211 is the portion of the outer profile 215 that can begin to tightly engage with the corresponding portion of the moving scroll blade 18) and the corresponding portion 181 of the moving scroll blade 18. The distal intake region 26 is defined between the starting portion 212 of the inner profile 214 of the fixed scroll blade 21 (the starting portion 212 is the portion of the inner profile 214 that can begin to tightly engage with the corresponding portion of the moving scroll blade 18) and the corresponding portion 183 of the moving scroll blade 18. The first oil outlet 15 communicates with the proximal intake region 25 and is located at the intake port of the proximal intake region 25, so that the lubricating oil discharged from the first oil outlet 15 can enter the proximal intake region 25 to lubricate the proximal intake region 25. The second oil outlet 16 is located radially outside the starting portion 181 of the moving vortex blade 18, and therefore is not directly connected to the near-end intake region 25. The starting end 191 of the oil channel 19 is connected to the second oil outlet 16 and extends clockwise from the second oil outlet 16 to the far-end intake region 26, so that the lubricating oil discharged from the second oil outlet 16 can flow through the oil channel 19 to lubricate the far-end intake region 26. The terminating end 192 of the oil channel 19 can be approximately aligned in the circumferential direction with the starting end 213 of the inner profile 214 of the fixed vortex blade 21, so that the terminating end 192 is located at the intake port of the far-end intake region 26, thereby allowing the lubricating oil flowing along the oil channel 19 to the terminating end 192 to enter the far-end intake region 26 to lubricate the far-end intake region 26. The starting end 213 of the inner profile 214 of the fixed scroll blade 21 roughly corresponds to the step portion on the inner side wall of the outer peripheral wall of the fixed scroll, and roughly corresponds to the position of the intake port of the distal intake region 26. During compressor operation, at the distal intake region 26, the fixed scroll blade 21 and the moving scroll blade 18 can intermittently engage and disengage to form a working chamber, and the working fluid is drawn into the working chamber.

[0037] Below, refer to Figures 2-4 The working principle of the lubrication structure of the vortex compression mechanism according to the first embodiment of the present invention will be described in detail.

[0038] During the operation of the scroll compressor including the scroll compression mechanism according to the first embodiment of the present invention, lubricating oil enters the inner space of the hub of the moving scroll from the oil sump at the bottom of the scroll compressor through a channel in the drive shaft, and enters the lubricating oil channel through the oil inlet hole. The lubricating oil entering the lubricating oil channel flows through the transverse hole of the lubricating oil channel, then enters the first oil outlet hole and the second oil outlet hole of the lubricating oil channel, and flows to the surface of the moving scroll end plate through the first oil outlet hole and the second oil outlet hole. At the same time, the working fluid enters the interior of the scroll compressor mechanism through the air inlet window (not shown) opened on the side wall of the fixed scroll, and then enters the working chamber formed by the relative movement of the moving scroll blades relative to the fixed scroll blades through the suction area of ​​the scroll compressor mechanism, and is compressed in the working chamber. During the operation of the scroll compressor, since the first oil outlet hole is connected to the proximal suction area of ​​the scroll compressor mechanism and is located at the suction port of the proximal suction area, the lubricating oil discharged from the first oil outlet hole can enter the proximal suction area with the working fluid to lubricate the proximal suction area. Furthermore, since the moving vortex end plate is provided with an oil delivery groove that communicates with the second oil outlet and extends to the air intake port of the far-end air intake area, the lubricating oil discharged from the second oil outlet can flow along the oil delivery groove to the air intake port of the far-end air intake area, and enter the far-end air intake area together with the working fluid to lubricate the far-end air intake area.

[0039] Therefore, in the scroll compressor mechanism according to the first embodiment of the present invention, sufficient lubrication of both the near-end and far-end intake regions of the scroll compressor mechanism can be achieved through an improved lubrication structure. Specifically, by providing an oil delivery groove, lubricating oil discharged from the lubricating oil channel can flow directly to the far-end intake region, ensuring sufficient lubricating oil for lubrication of the far-end intake region and solving the problem of insufficient lubricating oil for lubrication of the far-end intake region in scroll compressor mechanisms of related technologies. Therefore, in the scroll compressor mechanism according to the first embodiment of the present invention, the wear of the stationary scroll portion and the moving scroll portion that come into contact with each other during compressor operation at the far-end intake region of the scroll compressor mechanism—such as the stationary scroll blades and the moving scroll blades that come into contact with each other, the surface of the moving scroll that contacts the bottom of the stationary scroll blades, and the surface of the stationary scroll that contacts the top of the moving scroll blades—can be significantly improved.

Figures 5-7The overall structure and working principle of the lubrication structure of the scroll compressor mechanism according to the second embodiment of the present invention will be described in detail. The main difference between the scroll compressor mechanism according to the second embodiment of the present invention and the scroll compressor mechanism according to the first embodiment is the arrangement of the oil outlet and the oil delivery groove. The other configurations of the scroll compressor mechanisms are basically the same, so the relevant descriptions will be simplified or omitted.

As shown in the figure, the moving scroll 30 of the scroll compression mechanism includes a moving scroll end plate 31, in which a lubricating oil channel 32 is provided. The lubricating oil channel 32 includes an oil inlet 33, a transverse hole 34 communicating with the oil inlet 33, and an oil outlet 35, wherein the oil outlet 35 communicates with the transverse hole 34. The oil outlet 35 is provided in the moving scroll end plate 31. The oil inlet 33 of the lubricating oil channel 32 communicates with the inner space of the hub of the moving scroll 30, and the oil outlet 35 of the lubricating oil channel 32 opens onto the surface 36 of the moving scroll end plate 31. The lubricating oil entering the lubricating oil channel 32 from the oil inlet 33 can flow through the transverse hole 34 and then into the oil outlet 35, and flow through the oil outlet 35 to the surface 36 of the moving scroll end plate 31.

[0042] Figure 6 This is a top view of the moving scroll of the scroll compressor mechanism according to the second embodiment of the present invention. As shown, the moving scroll 30 of the scroll compressor mechanism includes moving scroll blades 37 extending vertically from the surface 36 of the moving scroll end plate 31. The moving scroll blades 37 include a starting end 372. The oil outlet 35 of the lubricating oil passage 32 is substantially aligned with the starting end 372 in the circumferential direction, and the oil outlet 35 is located radially inside the moving scroll blades 37 in the near-end intake region (see reference). Figure 7 An oil delivery groove 38 is provided on the surface 36 of the moving vortex end plate 31. This oil delivery groove 38 communicates with the oil outlet 35 and rotates counterclockwise (this counterclockwise direction is...). Figure 6 In this embodiment, the moving vortex extends in a counter-clockwise direction relative to the fixed vortex in a clockwise direction to the distal intake region of the vortex compression mechanism (which will be referred to below). Figure 7 (Detailed description).

[0043] Figure 7This is a schematic top cross-sectional view of the scroll compression mechanism according to the second embodiment of the present invention, wherein a fixed scroll blade and a moving scroll blade are nested together. As shown, the moving scroll blade 37 of the moving scroll 30 and the fixed scroll blade 41 of the fixed scroll 40 mesh with each other to form a working cavity. The fixed scroll blade 41 includes an inner profile 414 and an outer profile 415, wherein the inner profile 414 corresponds to the portion of the inner wall surface of the fixed scroll blade 41 that can form a tight mesh with the moving scroll blade 37, and the outer profile 415 corresponds to the portion of the outer wall surface of the fixed scroll blade 41 that can form a tight mesh with the moving scroll blade 37. The starting end of the inner profile 414 is at... Figure 7 As shown in 413, the starting end of the outer profile line 415 is at... Figure 7 The image is shown at 416. During compressor operation, working fluid can be drawn into the working chamber and compressed within it. The scroll compressor mechanism includes an intake region, which comprises a proximal intake region 45 and a distal intake region 46. The proximal intake region 45 is defined between the starting portion 411 of the outer profile 415 of the fixed scroll blade 41 and the corresponding portion 371 of the moving scroll blade 37. The distal intake region 46 is defined between the starting portion 412 of the inner profile 414 of the fixed scroll blade 41 and the corresponding portion 373 of the moving scroll blade 37. An oil outlet 35 communicates with the proximal intake region 45 and is located at the intake port of the proximal intake region 45, allowing lubricating oil discharged from the oil outlet 35 to enter the proximal intake region 45 for lubrication. The starting end of the oil delivery groove 38 is connected to the oil outlet 35 and extends counterclockwise from the oil outlet 35 to the distal air intake area 46, so that the lubricating oil discharged from the oil outlet 35 can flow through the oil delivery groove 38 to lubricate the distal air intake area 46.

[0044] Below, refer to Figures 5-7 The working principle of the lubrication structure of the vortex compression mechanism according to the second embodiment of the present invention will be described in detail.

[0045] During operation of the scroll compressor including the scroll compression mechanism according to the second embodiment of the present invention, lubricating oil enters the inner space of the hub of the moving scroll from the oil sump at the bottom of the scroll compressor through a channel in the drive shaft, and enters the lubricating oil channel through the oil inlet hole. The lubricating oil entering the lubricating oil channel flows through the transverse hole of the lubricating oil channel, then enters the oil outlet hole of the lubricating oil channel, and flows to the surface of the moving scroll end plate through the oil outlet hole. At the same time, the working fluid enters the interior of the scroll compressor mechanism through the air inlet window (not shown) opened on the side wall of the fixed scroll, and then enters the working chamber formed by the relative movement of the moving scroll blades relative to the fixed scroll blades through the suction area of ​​the scroll compressor mechanism, and is compressed in the working chamber. During the operation of the scroll compressor, since the oil outlet hole is connected to the proximal suction area of ​​the scroll compressor mechanism and is located at the suction port of the proximal suction area, the lubricating oil discharged from the oil outlet hole can enter the proximal suction area with the working fluid to lubricate the proximal suction area. Furthermore, since the moving vortex end plate is provided with an oil delivery groove that communicates with the oil outlet and extends to the far-end suction area, the lubricating oil discharged from the oil outlet can flow along the oil delivery groove to the far-end suction area to lubricate the far-end suction area.

[0046] Therefore, the scroll compressor mechanism according to the second embodiment of the present invention can also achieve sufficient lubrication of the near-end and far-end intake regions of the scroll compressor mechanism. Consequently, in the scroll compressor mechanism according to the second embodiment of the present invention, particularly in the far-end intake region of the scroll compressor mechanism, the wear of the stationary scroll portion and the moving scroll portion, which come into contact with each other during compressor operation, can be significantly improved. Furthermore, compared to the scroll compressor mechanism according to the first embodiment, the scroll compressor mechanism according to the second embodiment only requires one oil outlet, and the length of the oil delivery groove is relatively short, thus simplifying manufacturing and saving costs.

[0047] Furthermore, it should be noted that although the technical solutions of various embodiments of the vortex compression mechanism according to the present invention have been described above, it is understood that the technical solutions in the above embodiments are only illustrative and not restrictive. Not all features are necessary, and various feasible modifications can be made, as specifically exemplified below.

[0048] In the first embodiment, although a first oil outlet and a second oil outlet are provided, the first oil outlet can be omitted, and only the second oil outlet can be provided. In both the first and second embodiments, although the oil outlet is approximately aligned with the starting end of the moving vortex blade in the circumferential direction, the oil outlet can also be located at other positions in the circumferential direction, as long as it communicates with the near-end intake region. In the first embodiment, although the terminating end of the oil delivery groove is approximately aligned with the starting end of the inner profile of the fixed vortex blade in the circumferential direction, the terminating end of the oil delivery groove can also be located at other positions in the circumferential direction, as long as it communicates with the far-end intake region.

[0049] This utility model also provides a scroll compressor, which includes the scroll compression mechanism described above.

[0050] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the specific embodiments described and shown herein, and various changes can be made to the exemplary embodiments by those skilled in the art without departing from the scope defined by the claims.
