Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a static scroll structure and a compressor. Background Technology

[0002] Currently, scroll compressors consist of a stationary scroll, a moving scroll, and a crankshaft. The moving scroll is mounted on the crankshaft and is assembled with the stationary scroll, allowing it to move relative to it. During operation, the crankshaft undergoes eccentric motion, while the moving scroll revolves, thus realizing the compressor's intake, compression, and exhaust processes. After assembly, the stationary and moving scrolls come into contact. During compressor operation, the surfaces of the moving and stationary scrolls press and rub against each other to seal the chamber. This pressing and friction between the moving and stationary scroll surfaces easily leads to abnormal wear. Therefore, an oil groove structure is usually provided on the stationary scroll surface, and oil is supplied to the oil groove through an oil supply hole on the moving scroll surface. The movement of the moving scroll lubricates the surfaces of the moving and stationary scrolls. However, this lubrication structure still suffers from insufficient lubrication, leading to inter-scroll wear. Summary of the Invention

[0003] The main objective of this invention is to propose a static scroll structure and compressor, which aims to solve the problem of insufficient lubrication between the static and dynamic scrolls.

[0004] To achieve the above objectives, the present invention proposes a static vortex disk structure, which includes a static vortex disk having a mounting end face for mounting in conjunction with a moving vortex disk.

[0005] An oil groove is also provided on the mounting end face. The oil groove includes multiple oil groove segments. The multiple oil groove segments are arranged at intervals along the circumference of the stationary volute and all extend along the circumference of the stationary volute. Each oil groove segment can be connected to the oil supply hole provided on the moving volute.

[0006] In one embodiment, two adjacent oil tank segments include two first oil tank segments, and each of the two first oil tank segments has a connecting portion at one adjacent end. The two connecting portions are respectively arranged on the active path of the same oil supply hole.

[0007] In one embodiment, the two conductive portions are spaced apart to alternately connect the corresponding oil supply holes.

[0008] In one embodiment, at least one of the conductive parts is provided with a conductive groove, which is extended along the direction of the active path of the oil supply hole, and the conductive groove is laterally connected to the corresponding first oil groove segment.

[0009] In one embodiment, two oil tank sections are provided, and the opposite ends of the two oil tank sections are arranged adjacent to each other.

[0010] The present invention also provides a compressor, comprising:

[0011] Static vortex disk; and,

[0012] A moving scroll plate is disposed on one side of the mounting end face of the stationary scroll plate, and an oil supply path is formed on the moving scroll plate, wherein an oil supply hole is provided on the oil supply path.

[0013] The stationary vortex disk has a mounting end face for installation in conjunction with the moving vortex disk;

[0014] An oil groove is also provided on the mounting end face. The oil groove includes multiple oil groove segments. The multiple oil groove segments are arranged at intervals along the circumference of the stationary volute and all extend along the circumference of the stationary volute. Each oil groove segment can be connected to the oil supply hole provided on the moving volute.

[0015] In one embodiment, a first back pressure chamber is formed inside the compressor, located outside the moving scroll plate, and the first back pressure chamber is connected to the oil supply path;

[0016] At least a portion of the oil trough section is configured as a connected oil trough section, and the connected oil trough section is at least partially located outside the active envelope area of ​​the moving scroll plate, so that the connected oil trough section can be located outside the oil supply hole and connected to the first back pressure chamber.

[0017] In one embodiment, the connecting oil trough section extends to the outside of the active envelope region of the moving vortex disk.

[0018] In one embodiment, the connecting oil tank section is partially widened to form an expansion portion, which is located outside the active envelope region of the moving vortex disk.

[0019] In one embodiment, a second back pressure chamber is formed within the compressor on the side of the moving scroll disk facing away from the stationary scroll disk;

[0020] The oil inlet of the oil supply path is connected to the second back pressure chamber.

[0021] In one embodiment, a crankshaft is provided in the second back pressure chamber, and an oil supply channel is formed in the crankshaft, the oil supply channel being connected to the second back pressure chamber.

[0022] In the technical solution of this invention, the stationary scroll plate has an installation end face to form a compression chamber with the moving scroll plate. This allows the refrigerant in the compression chamber to be compressed during the revolution of the moving scroll plate. Furthermore, by providing oil grooves, lubrication is provided to the surface between the stationary and moving scroll plates. The multiple oil groove segments reduce the length of each segment, allowing for individual installation of each segment to fully utilize the space of the installation end face and reduce space requirements on the plate surface. This also ensures that lubricating oil flows to the tail end of each oil groove segment, guaranteeing oil supply and reducing the risk of wear at the tail end of the oil groove. This solves the problem of insufficient lubrication between the stationary and moving scroll plates. Attached Figure Description

[0038] Currently, scroll compressors consist of a stationary scroll, a moving scroll, and a crankshaft. The moving scroll is mounted on the crankshaft and is assembled with the stationary scroll, allowing it to move relative to it. During operation, the crankshaft undergoes eccentric motion, while the moving scroll revolves, thus realizing the compressor's intake, compression, and exhaust processes. After assembly, the stationary and moving scrolls come into contact. During compressor operation, the surfaces of the moving and stationary scrolls press and rub against each other to seal the chambers. This pressing and friction between the moving and stationary scroll surfaces easily leads to abnormal wear. Therefore, an oil groove structure is typically provided on the stationary scroll surface, and oil is supplied to the oil groove through an oil supply hole on the moving scroll surface. Driven by the rotation of the moving scroll, lubrication is achieved between the moving and stationary scroll surfaces. The lubricated oil then flows to the adjacent compression chamber and back pressure chamber.

[0039] The oil grooves of existing stationary scroll plates are usually arranged in a nearly 360-degree circle so that they can provide lubrication within a 360-degree range of the contact surface between the stationary and moving scroll plates, thereby improving the wear resistance of the plate surface. However, if the oil grooves are too long, the lubricating oil supply in the tail area of ​​the oil grooves will be insufficient, resulting in insufficient lubrication between the stationary and moving scroll plates, making the plate surface prone to wear.

[0040] This invention proposes a stationary scroll structure for use in compressors, aiming to solve the problem of insufficient lubrication between the moving and stationary scrolls. Specifically, Figures 1 to 5 A schematic diagram of the static vortex disk structure provided by the present invention; Figure 6 This is a schematic diagram of the compressor provided by the present invention.

[0041] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of the present invention, the stationary vortex disk structure 100 includes a stationary vortex disk 1, which has a mounting end face 11 for mounting in conjunction with a moving vortex disk 4. An oil groove 2 is also provided on the mounting end face 11. The oil groove 2 includes a plurality of oil groove segments 21, which are spaced apart along the circumference of the stationary vortex disk 1 and all extend along the circumference of the stationary vortex disk 1. Each oil groove segment 21 can be connected to an oil supply hole 42 provided on the moving vortex disk 4.

[0042] In the technical solution of the present invention, the stationary scroll plate 1 has an installation end face 11 to form a compression chamber with the moving scroll plate 4. When the moving scroll plate 4 revolves, it can compress the refrigerant in the compression chamber. By setting the oil groove 2, it lubricates the disk surface between the stationary scroll plate 1 and the moving scroll plate 4. At the same time, by setting multiple oil groove segments 21, the length of each oil groove segment 21 is reduced. Each oil groove segment 21 can be set separately to make full use of the space of the installation end face 11, reducing the requirements for disk surface space. It also allows the lubricating oil to flow to the tail end of the oil groove segment 21, ensuring the oil supply to the tail end of the oil groove segment 21 and helping to reduce the risk of wear at the tail end of the oil groove 2. Thus, the problem of insufficient lubrication between the moving and stationary scroll plates 1 is solved.

[0043] It should be noted that you should refer to [link / reference]. Figure 7 In existing systems, the oil grooves 2 on the stationary scroll plate 1 are typically arranged 360 degrees along the circumference of the stationary scroll plate 1 to lubricate the entire circumferential surface of both the stationary scroll plate 1 and the moving scroll plate 4. However, in this lubrication structure, the length of the oil grooves 2 is too long, which may prevent the lubricating oil from flowing to the tail end of the oil grooves 2. This can lead to insufficient lubrication at the tail end of the oil grooves 2, causing wear on the surfaces of the moving scroll plate 4 and the stationary scroll plate 1. Furthermore, due to the distance from the oil grooves 2 to the compression chamber and the outer edge of the moving plate, the lubrication may be insufficient. The distance between the edges cannot be too small, and usually needs to be at least greater than 0.5mm. If the oil groove 2 is too long, and the space on the disc surface is limited, it is difficult to meet the sealing requirements. Therefore, in this embodiment, multiple oil groove segments 21 are set to reduce the length of each oil groove segment 21. This makes it easier to set the oil groove segment 21 and allows the lubricating oil to flow smoothly to the tail end of the oil groove segment 21 to lubricate the disc surface at the tail end of the oil groove segment 21, which can effectively improve the wear of the disc surface at the tail end of the oil groove segment 21.

[0044] In one embodiment of the present invention, please refer to Figure 2 and Figure 4 Each of the two adjacent oil tank sections 21 includes two first oil tank sections. A guide portion 3 is provided at one adjacent end of each of the two first oil tank sections. Both guide portions 3 are correspondingly arranged on the moving path of the same oil supply hole 42. Thus, by placing the two guide portions 3 at the adjacent ends of the two first oil tank sections, they are positioned on the moving path of the same oil supply hole 42 on the moving scroll plate 4. Furthermore, by placing the two guide portions 3 on the moving path of the same oil supply hole 42, one oil supply hole 42 on the moving scroll plate 4 can supply oil to both oil tank sections 21, thereby simplifying the oil supply structure. Of course, in other embodiments, multiple oil tank sections 21 can also be individually supplied with oil through multiple oil supply holes 42 on the moving scroll plate 4, etc., and this invention does not limit this.

[0045] During the operation of the compressor 1000, the moving scroll plate 4 is subjected to tangential gas force and normal centrifugal force. The normal centrifugal force causes the moving scroll plate 4 to tilt around the tangential axis. At certain rotation angles, the oil supply pressure will worsen the contact force. Therefore, it is necessary to control the oil supply pressure. To this end, in this embodiment, two connecting parts 3 are arranged at intervals to alternately connect the corresponding oil supply holes 42. When one of the connecting parts 3 is connected to the oil supply hole 42, the other connecting part 3 is disconnected from the oil supply hole 42. In this way, when the moving scroll plate 4 revolves, the oil supply hole 42 can connect to the two connecting parts 3 respectively, so that the oil supply hole 42 can alternately supply oil to the two oil groove sections 21. Oil is supplied when the oil groove section 21 needs oil and stopped when oil supply is not needed, thereby reducing the tilting torque on the moving scroll plate 4 and thus helping to improve the wear of the plate surface between the stationary scroll plate 1 and the moving scroll plate 4.

[0046] It is understood that the distance between the two conductive parts 3 needs to be at least greater than the diameter of the oil supply hole 42 in order to ensure that the oil supply hole 42 is not simultaneously connected to the two conductive parts 3.

[0047] Furthermore, at least one of the guiding parts 3 is provided with a guiding groove 31, which is extended along the direction of the active path of the oil supply hole 42. The guiding groove 31 is laterally connected to the corresponding first oil groove segment. In this way, by providing a guiding groove 31 that extends along the active path of the oil supply hole 42, the guiding groove 31 and the oil supply hole can be connected at the designed operating angle, thereby controlling the oil supply of the oil supply hole.

[0048] It is understood that, due to the revolution of the moving scroll plate 4 around the center of the stationary scroll plate 1, the oil supply hole 42 on the moving scroll plate also revolves. Depending on the shape of the guide section 3, the moving scroll plate 4 and the stationary scroll plate 1 can communicate at different operating angles, allowing the oil supply hole 42 to supply oil to the oil groove 2 on the stationary scroll plate 1. Furthermore, the operating angle at which the guide groove 31 communicates with the oil supply hole 42 can be adjusted as needed, and this invention does not limit this. For example, the guide groove 31 can have various shapes, such as semi-circular or arc-shaped, as long as it can communicate with the oil supply hole 42 at a preset operating angle; this invention does not limit this.

[0049] The number of oil groove segments 21 can vary, including one, two, three, or four, etc. This invention does not limit the number. However, the more oil groove segments 21 there are, the more complex the corresponding oil supply structure becomes, and the higher the manufacturing difficulty. Therefore, in this embodiment, two oil groove segments 21 are provided, with their opposite ends adjacent to each other. This significantly reduces the length of the oil groove segments 21, allowing lubricating oil to flow smoothly to the tail ends of each segment for lubrication. It also simplifies the oil supply structure and reduces the manufacturing difficulty of the static vortex disk structure 100. Furthermore, the lengths of the multiple oil groove segments 21 can be the same or different; this invention limits this. Specifically, in this embodiment, the lengths of all oil groove segments 21 are the same to ensure uniform distribution of lubricating oil within each segment.

[0050] The present invention also proposes a compressor 1000, please refer to [link / reference]. Figure 6 The compressor 1000 includes a stationary scroll 1 and a moving scroll 4. The moving scroll 4 is disposed on one side of the mounting end face 11 of the stationary scroll 1. An oil supply path 41 is formed on the moving scroll 4, and an oil supply hole 42 is provided on the oil supply path 41. Thus, the moving scroll 4 is disposed on one side of the mounting end face 11 of the stationary scroll 1 to form a compression chamber with the stationary scroll 1. When the moving scroll 4 revolves, it can compress the refrigerant in the compression chamber. At the same time, by setting the oil supply path 41 and the oil supply hole 42, oil is supplied to the multiple oil groove sections 21 on the stationary scroll 1 to lubricate the disc surface between the moving scroll 4 and the stationary scroll 1, thereby improving the disc surface wear between the moving scroll 4 and the stationary scroll 1. The specific structure of the static scroll disk structure 100 is as described in the above embodiments. Since the compressor 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0051] In one embodiment of the present invention, please refer to Figure 2 and Figure 3A first back pressure chamber 51 is formed inside the compressor 1000, located outside the moving scroll plate 4. The first back pressure chamber 51 is connected to the oil supply path 41. At least a portion of the oil groove section 21 is configured as a connecting oil groove section 211. The connecting oil groove section 211 is at least partially located outside the active envelope region 7 of the moving scroll plate 4, so that the connecting oil groove section 211 can be located outside the oil supply hole 42 and connected to the first back pressure chamber 51. Thus, the first back pressure chamber 51 is used to collect the lubricating oil flowing between the moving scroll plate 4 and the stationary scroll plate 1. At the same time, by setting the connecting oil groove section 211, when the corresponding connecting part 3 is not connected to the oil supply hole 42, the first back pressure chamber 51 can be connected to draw oil from the first back pressure chamber 51 to avoid insufficient lubrication of the disc surface between the moving scroll plate 4 and the stationary scroll plate 1.

[0052] It should be noted that the active envelope region 7 refers to the maximum active area of ​​the moving scroll plate 4 on the stationary scroll plate 1. If the radius of the moving scroll plate 4 is r, the eccentricity of the moving scroll plate 4 is e, and the outer diameter of the active envelope region 7 is R, then the active envelope region 7 is the region with the center of the stationary scroll plate 1 as the center and a radius of R = r + 2e. Furthermore, the compression angle between the oil groove section 21 and the oil supply port 42 is greater than the compression angle between the connected oil groove section 211 and the first back pressure chamber 51, to prevent the oil supply port 42 and the first back pressure chamber 51 from simultaneously supplying oil to both oil groove sections 21.

[0053] There are various ways to configure the connecting oil tank section 211. Specifically, in one embodiment of the present invention, please refer to 4 and Figure 5 The connecting oil groove segment 211 extends to the outside of the active envelope region 7 of the moving scroll plate 4. Thus, by extending the connecting oil groove segment 211 to the active envelope region 7, when the oil supply hole 42 is not connected to the oil groove segment 21 corresponding to the connecting oil groove segment 211, the oil groove segment 21 corresponding to the connecting oil groove segment 211 can be connected to the first back pressure chamber 51 so as to draw oil from the first back pressure chamber 51.

[0054] In another embodiment of the present invention, the connecting oil groove segment 211 is partially widened to form an expansion portion 2111. The expansion portion 2111 is located outside the active envelope region 7 of the moving scroll plate 4. Thus, by providing the expansion portion 2111, when the oil supply hole 42 is not connected to the oil groove segment 21 corresponding to the expansion portion 2111, the corresponding oil groove segment 21 can be connected to the first back pressure chamber 51 so as to draw oil from the first back pressure chamber 51.

[0055] In one embodiment of the present invention, please refer to Figure 6A second back pressure chamber 52 is formed in the compressor 1000 on the side of the moving scroll 4 facing away from the stationary scroll 1. The oil inlet of the oil supply path 41 is connected to the second back pressure chamber 52. Thus, by setting the second back pressure chamber 52, oil is supplied to the oil supply path 41, so that lubricating oil can flow into the oil sump 2 through the oil supply path 41 to lubricate the disk surface between the moving scroll 4 and the stationary scroll 1.

[0056] Furthermore, a crankshaft 6 is provided in the second back pressure chamber 52, and an oil supply channel 61 is formed in the crankshaft 6. The oil supply channel 61 is connected to the second back pressure chamber 52. In this way, by setting the oil supply channel 61, lubricating oil in the oil pan is input into the second back pressure chamber 52 so as to supply oil to the oil supply flow path 41.

[0057] The following description will be based on the above embodiments, taking multiple oil tank sections 21 as examples, namely oil tank A and oil tank B:

[0058] When the compression angle of the compressor 1000 is -60° to 80°, oil sump A is connected to oil supply port 42, oil sump B is not connected to oil supply port 42, but may be connected to the first back pressure chamber 51.

[0059] When the compression angle of the compressor 1000 is -30° to 30°, oil sump A is connected to oil supply port 42, oil sump B is not connected to oil supply port 42, but is connected to the first back pressure chamber 51;

[0060] When the compression angle of the compressor 1000 is 80° to 120°, neither oil sump A nor oil sump B is connected to the oil supply hole 42, nor is it connected to the first back pressure chamber 51.

[0061] When the compression angle of the compressor 1000 is 120° to 260°, oil groove A is not connected to oil supply hole 42, but may be connected to the first back pressure chamber 51, and oil groove B is connected to oil supply hole 42.

[0062] When the compression angle of the compressor 1000 is 150° to 210°, oil groove A is not connected to oil supply hole 42, but is connected to the first back pressure chamber 51, and oil groove B is connected to oil supply hole 42.

[0063] When the compression angle of the compressor 1000 is 260° to 300°, neither oil sump A nor oil sump B is connected to the oil supply hole 42, nor is it connected to the first back pressure chamber 51.

[0064] The connection angles between oil tank A and oil tank B are specifically shown in Table 1.
