Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to scroll plates, scroll assemblies and scroll compressors. Background Technology

[0002] A scroll compressor typically consists of a stationary scroll and a moving scroll. The compression chamber is formed between the stationary scroll and the moving scroll. The sealing effect between the end face of the stationary scroll teeth near the moving scroll body and the moving scroll body, as well as the sealing effect between the end face of the moving scroll teeth near the stationary scroll body and the stationary scroll body, are important factors affecting the working performance of the compression chamber.

[0003] Currently, in order to improve the working performance of the compression chamber, sealing structures are usually provided on both the end face of the stationary rotary tooth near the moving disc and the end face of the moving rotary tooth near the stationary disc in related technologies. Taking the sealing structure on the end face of the stationary rotary tooth near the moving disc as an example, a groove is recessed on the end face of the stationary rotary tooth near the moving disc. The groove is used to accommodate the sealing gasket and restrict the movement of the sealing gasket along the axial direction of the stationary rotary tooth. The sealing gasket seals the gap between the end face of the stationary rotary tooth near the moving disc and the moving disc, but the problem of sealing gasket leakage and failure is prone to occur.

[0010] As an alternative to the aforementioned vortex disk, the first pad and the second pad surfaces are in contact; and / or,

[0011] The thickness of the first pad is less than the thickness of the second pad.

[0012] As an alternative to the aforementioned vortex disk, the end face of the first pad near the second pad is the first end face, and the end face of the second pad near the first pad is the second end face. The first end face and the second end face have the same shape and are aligned around the perimeter.

[0013] As an alternative to the aforementioned scroll disk, the tensile modulus of the first pad is greater than 200 GPA; and / or,

[0014] The tensile modulus of the second pad is less than 2.5 GPA.

[0015] As an alternative to the aforementioned scroll disk, the first pad is made of carbon steel, stainless steel, or aluminum alloy; and / or,

[0016] The second pad is made of polyphenylene sulfide, polybutylene terephthalate or polypropylene.

[0017] As an optional embodiment of the aforementioned scroll plate, the sealing assembly includes at least two elastic elements, and the second limiting groove is provided in at least two sets. The at least two elastic elements and the at least two sets of second limiting grooves are arranged in a one-to-one correspondence. Each set of second limiting grooves includes a second limiting groove recessed on the end face of the first pad near the bottom wall of the first limiting groove and / or a second limiting groove recessed on the bottom wall of the first limiting groove; and / or,

[0018] The number of sealing components is at least two, and the at least two sealing components are distributed at radial intervals along the spiral teeth.

[0019] As an alternative to the aforementioned scroll plate, the scroll plate is a first scroll plate, and the scroll plate body of the first scroll plate can form a compression cavity with the second scroll plate; a gap is formed between the bottom wall of the first pad and the first limiting groove.

[0020] The rotary tooth is provided with a first channel, the first channel connecting the compression chamber and the gap; and / or, the first pad and the second pad form a second channel, the second channel connecting the compression chamber and the gap.

[0023] A scroll compressor, including the scroll disc described above, or including the scroll assembly described above.

[0024] The beneficial effects of this utility model are:

[0025] This utility model provides a scroll disk, which includes a scroll disk body and a sealing assembly. The scroll disk body includes a disk body and a spiral tooth connected to one axial end of the disk body. The top surface of the spiral tooth is recessed with a first limiting groove. The sealing assembly includes a first pad, an elastic element, and a second pad. The first pad is accommodated in the first limiting groove, which limits the movement of the first pad along the axial direction of the spiral tooth. The bottom wall of the first limiting groove and / or the end face of the first pad near the bottom wall of the first limiting groove is recessed with a second limiting groove. The elastic element is partially accommodated in the second limiting groove, which limits the expansion and contraction of the elastic element along the axial direction of the spiral tooth. The elastic element applies a force to the first pad along the direction from the root to the tip of the spiral tooth. Along the axial direction of the spiral tooth, the second pad is disposed on the side of the first pad away from the elastic element. The second pad can move synchronously with the first pad along the axial direction of the spiral tooth relative to the first limiting groove, and the tensile modulus of the second pad is less than that of the first pad.

[0026] By setting a first pad between the elastic element and the second pad, the elastic deformation force of the elastic element is transmitted to the second pad through the first pad. It can be understood that the force transmitted from the first pad to the second pad is a surface force, which can effectively improve the uniformity of the force on the second pad and effectively prevent the upper part of the second pad from being lifted by the elastic element and prematurely contacting the disc body of the other scroll plate, thereby effectively improving the sealing performance and service life of the second pad.

[0027] Secondly, by setting the tensile modulus of the second pad to be less than that of the first pad, it can be understood that the second pad is more flexible than the first pad. The second pad is used to abut against the disc body of another scroll plate, thereby further improving the sealing performance of the second pad.

[0028] Secondly, by recessing a second limiting groove on the bottom wall of the first limiting groove and / or on the end face of the first pad near the bottom wall of the first limiting groove, the second limiting groove can limit the setting position of the elastic element, effectively preventing the elastic element from tilting and / or shifting, thereby effectively preventing the second pad from failing to effectively abut against the disc body of the other scroll plate to achieve a seal due to the tilting and / or shifting of the elastic element, thus further improving the sealing performance of the second pad.

[0029] Therefore, compared with the existing technology, the scroll plate has a simple structure, fewer parts, high assembly and disassembly efficiency, low production cost, and can effectively improve the sealing performance and service life of the second gasket.

[0030] This invention also provides a scroll assembly, including the aforementioned scroll disk. By employing the scroll disk, the working performance and assembly efficiency of the scroll assembly can be effectively improved, and the production cost of the scroll assembly can be effectively reduced.

[0031] This utility model also provides a scroll compressor, including the aforementioned scroll disc, or including the aforementioned scroll assembly.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0042] Scroll compressors typically consist of a stationary scroll and a moving scroll, forming a compression chamber. The sealing effect between the stationary scroll's teeth near the moving scroll body and the moving scroll body, as well as the sealing effect between the moving scroll's teeth near the stationary scroll body and the stationary scroll body, are crucial factors affecting the compression chamber's performance. Currently, to improve compression chamber performance, sealing structures are typically installed on both the stationary and moving scroll teeth near the stationary scroll body. Taking the sealing structure on the stationary scroll near the moving scroll body as an example, a groove is recessed on the stationary scroll near the moving scroll body. This groove accommodates a sealing gasket and restricts its axial movement along the stationary scroll teeth. The sealing gasket seals the gap between the stationary scroll's teeth and the moving scroll body, but this method is prone to leakage and failure.

[0043] This utility model provides a scroll disk, such as Figure 1-3As shown, the scroll disk includes a scroll disk body 1 and a sealing assembly 2. The scroll disk body 1 includes a disk body 11 and a spiral tooth 12 connected to one axial end of the disk body 11. The top surface of the spiral tooth 12 is recessed with a first limiting groove 121. The sealing assembly 2 includes a first gasket 21, an elastic element 22, and a second gasket 23. The first gasket 21 is housed in a first limiting groove 121, which limits the axial movement of the first gasket 21 along the helical teeth 12. A second limiting groove 122 is recessed on the bottom wall of the first limiting groove 121 and / or on the end face of the first gasket 21 near the bottom wall of the first limiting groove 121. The elastic element 22 is partially housed in the second limiting groove 122, which limits the expansion and contraction of the elastic element 22 along the axial direction of the helical teeth 12. The elastic element 22 applies a force to the first gasket 21 along the direction from the root to the tip of the helical teeth 12. Along the axial direction of the helical teeth 12, the second gasket 23 is disposed on the first gasket 21 on the side away from the elastic element 22. The second gasket 23 can move synchronously with the first gasket 21 along the axial direction of the helical teeth 12 relative to the first limiting groove 121, and the tensile modulus of the second gasket 23 is less than that of the first gasket 21.

[0044] When the bottom wall of the first limiting groove 121 is recessed with the second limiting groove 122, along the axial direction of the spiral tooth 12, the two ends of the elastic member 22 abut against the bottom wall of the second limiting groove 122 and the first pad 21 in a corresponding manner.

[0045] When the second limiting groove 122 is recessed on the end face of the first pad 21 near the bottom wall of the first limiting groove 121, along the axial direction of the spiral tooth 12, the two ends of the elastic member 22 abut against the bottom wall of the second limiting groove 122 and the bottom wall of the first limiting groove 121 in a corresponding manner.

[0046] When the bottom wall of the first limiting groove 121 is recessed with a second limiting groove 122, and the end face of the first pad 21 near the bottom wall of the first limiting groove 121 is also recessed with a second limiting groove 122, along the axial direction of the helical tooth 12, both ends of the elastic member 22 abut against the bottom walls of the two second limiting grooves 122. It can be understood that of the two second limiting grooves 122, one is the second limiting groove 122 recessed in the bottom wall of the first limiting groove 121, and the other is the second limiting groove 122 recessed on the end face of the first pad 21 near the bottom wall of the first limiting groove 121.

[0047] By setting a first pad 21 between the elastic element 22 and the second pad 23, the elastic deformation force of the elastic element 22 is transmitted to the second pad 23 through the first pad 21. It can be understood that the force transmitted from the first pad 21 to the second pad 23 is a surface force, which can effectively improve the uniformity of the force on the second pad 23 and effectively prevent the upper part of the second pad 23 from being lifted by the elastic element 22 and prematurely contacting the disc body of the other scroll plate, thereby effectively improving the sealing performance and service life of the second pad 23.

[0048] Secondly, by setting the tensile modulus of the second pad 23 to be less than that of the first pad 21, it can be understood that the second pad 23 is more flexible than the first pad 21. The second pad 23 is used to abut against the disc body of another scroll plate, thereby further improving the sealing performance of the second pad 23.

[0049] Secondly, by recessing a second limiting groove 122 on the bottom wall of the first limiting groove 121 and / or on the end face of the first pad 21 near the bottom wall of the first limiting groove 121, the second limiting groove 122 can limit the setting position of the elastic member 22, effectively preventing the elastic member 22 from tilting and / or shifting, thereby effectively preventing the second pad 23 from failing to effectively abut against the disc body of the other scroll plate to achieve a seal due to the tilting and / or shifting of the elastic member 22, thereby further improving the sealing performance of the second pad 23.

[0050] Therefore, compared with the existing technology, the scroll plate has a simple structure, fewer parts, high assembly and disassembly efficiency, low production cost, and can effectively improve the sealing performance and service life of the second gasket 23.

[0051] It is understandable that the axial direction of the helical tooth 12 is parallel to the direction from the root to the tip of the helical tooth 12. Figure 1 The direction from bottom to top is the direction from the root to the tip of helical tooth 12. Along Figure 1 In the vertical direction, the top surface of the spiral tooth 12 is the tooth tip surface of the spiral tooth 12, and the tooth root of the spiral tooth 12 is fixedly connected to the disk body 11.

[0052] Specifically, for a stationary scroll disk, the scroll disk body 1 is the stationary scroll disk body, the disk body 11 is the stationary disk, and the spiral teeth 12 are stationary spiral teeth. Furthermore, the second pad 23 of the stationary spiral teeth abuts against the moving disk of the moving scroll disk along the axial direction of the stationary scroll disk. This effectively seals the gap between the stationary spiral teeth and the moving disk along the axial direction of the stationary scroll disk, and significantly improves the sealing effect compared to existing technologies.

[0053] Specifically, for a scroll disk that is a moving scroll disk, the scroll disk body 1 is the moving scroll disk body, the disk body 11 is the moving disk, and the spiral teeth 12 are the moving spiral teeth. Further, the second pad 23 of the moving spiral teeth abuts against the stationary disk of the stationary scroll disk along the axial direction of the moving scroll disk. This effectively seals the gap between the moving spiral teeth and the stationary disk along the axial direction of the moving scroll disk, and significantly improves the sealing effect compared to existing technologies.

[0054] Specifically, the axial direction of the vortex disk, the axial direction of the stationary vortex, the axial direction of the moving vortex, the axial direction of the vortex disk body 1, the axial direction of the stationary vortex disk body, the axial direction of the moving vortex disk body, the axial direction of the stationary disk, the axial direction of the moving disk, the axial direction of the stationary rotary teeth, the axial direction of the moving rotary teeth, the depth direction of the first limiting groove 121, and the depth direction of the second limiting groove 122 are all parallel.

[0055] Specifically, in this embodiment, as Figure 3 As shown, the bottom wall of the first limiting groove 121 is recessed with a second limiting groove 122.

[0056] Specifically, in this embodiment, as Figure 3 As shown, the elastic element 22 is a spring. As an alternative, the elastic element 22 can also be made of an elastic material such as rubber.

[0057] Optionally, such as Figure 3 As shown, the shape of the first limiting groove 121 is the same as the shape of the first pad 21, and the cross-sectional dimension of the first limiting groove 121 along the depth direction is slightly larger than the end face dimension of the first pad 21 along the depth direction of the first limiting groove 121. This allows the first limiting groove 121 to limit the movement of the first pad 21 along the depth direction of the first limiting groove 121.

[0058] As an alternative, on the inner peripheral wall of the first limiting groove 121 and the outer peripheral wall of the first pad 21, one is provided with a guide groove extending along the depth direction of the first limiting groove 121, and the other is provided with a guide block, which slides within the guide groove. This also achieves the goal of limiting the movement of the first pad 21 along the depth direction of the first limiting groove 121.

[0059] Optionally, such as Figure 3 As shown, the shape of the second limiting groove 122 is the same as that of the elastic member 22, and the cross-sectional dimension of the second limiting groove 122 along the depth direction is slightly larger than the cross-sectional dimension of the elastic member 22 along the depth direction of the second limiting groove 122. This allows the second limiting groove 122 to limit the extension and retraction of the elastic member 22 along the depth direction of the second limiting groove 122.

[0060] As an alternative, a guide post is provided within the second limiting groove 122, and the elastic element 22 is sleeved on the outer periphery of the guide post. The guide post does not extend beyond the second limiting groove 122 along its depth direction. This also allows the elastic element 22 to be limited to extend and retract along the depth direction of the second limiting groove 122.

[0061] Optionally, the first pad 21 and the second pad 23 are in surface contact. This can further reduce the number of parts and further improve assembly efficiency.

[0062] along Figure 1 In the vertical direction, the first pad 21 and the second pad 23 are in surface contact, and the second pad 23 is supported on the top of the first pad 21. Along Figure 3 In the vertical direction, the first pad 21 and the second pad 23 are in contact, and the second pad 23 is supported on the top of the first pad 21.

[0063] It is understandable that, along the axial direction of the vortex disk body 1, with the elastic element 22 located above the first pad 21 and the first pad 21 located above the second pad 23, the first pad 21 and the second pad 23 are in surface contact, and the first pad 21 is supported on the top of the second pad 23.

[0064] As an alternative, the first pad 21 and the second pad 23 are fixedly connected. The fixed connection methods include, but are not limited to, adhesive bonding and plugging.

[0065] Optionally, such as Figure 3 As shown, the thickness of the first pad 21 is less than the thickness of the second pad 23. By reducing the weight of the first pad 21 while maintaining its function, the total weight of the scroll plate can be reduced.

[0066] As an alternative, the thickness of the first pad 21 is equal to the thickness of the second pad 23. As another alternative, the thickness of the first pad 21 is greater than the thickness of the second pad 23.

[0067] Furthermore, such as Figure 3 As shown, when the second limiting groove 122 is recessed only on the bottom wall of the first limiting groove 121, it is preferable that the thickness of the first pad 21 is less than the thickness of the second pad 23. This is sufficient to ensure the function of the first pad 21.

[0068] Furthermore, when the second limiting groove 122 is recessed only on the end face of the groove bottom wall near the first limiting groove 121 on the first pad 21, the thickness of the first pad 21 can be appropriately increased so as to increase the depth of the second limiting groove 122, thereby further improving the effect of preventing the elastic member 22 from tipping over and / or shifting, and simplifying the structure of the first limiting groove 121.

[0069] Among them, such as Figure 3 As shown, the end face of the first pad 21 that is close to the second pad 23 is the first end face, and the end face of the second pad 23 that is close to the first pad 21 is the second end face.

[0070] Optionally, such as Figure 3 As shown, the first end face and the second end face have the same shape and are aligned around the perimeter. This can further improve the uniformity of force distribution on the second gasket 23, thereby further improving the sealing performance of the second gasket 23.

[0071] As an alternative, the orthographic projection of the first end face completely covers the second end face along the axial direction of the scroll disk body 1. As another alternative, the orthographic projection of the second end face completely covers the first end face along the axial direction of the scroll disk body 1.

[0072] In this embodiment, it is preferable that the first end face and the second end face are in surface contact, and the first end face and the second end face have the same shape and are aligned around the perimeter.

[0073] Optionally, the elastic element 22 and the first pad 21 are connected by abutment. Compared with a fixed connection between the elastic element 22 and the first pad 21, this can further reduce the number of parts and further improve assembly efficiency.

[0074] As an alternative, the connection between the elastic element 22 and the first pad 21 can be by bonding, interference fit, etc. In particular, if the elastic element 22 is a metal spring and the first pad 21 is made of metal material, welding or other methods can also be used.

[0075] Optionally, the elastic element 22 and the helical tooth 12 are connected by abutment. Compared with a fixed connection between the elastic element 22 and the helical tooth 12, this can further reduce the number of parts and further improve assembly efficiency.

[0076] As an alternative, the connection between the elastic element 22 and the spiral tooth 12 can be achieved by bonding, interference fit, etc. In particular, if the elastic element 22 is a metal spring, welding or other methods can also be used.

[0077] It is understood that the tensile modulus of the second pad 23 is less than that of the first pad 21, meaning the second pad 23 is more easily deformed than the first pad 21. In this embodiment, the tensile modulus of the first pad 21 is exemplaryly set to be greater than 200 GPA, and the tensile modulus of the second pad 23 is less than 2.5 GPA. This makes the second pad 23 more easily deformable than the first pad 21. Specifically, the tensile modulus refers to the ratio of stress to strain within the elastic deformation range of a material, reflecting the material's ability to resist tensile deformation.

[0078] Optionally, the first pad 21 is made of carbon steel. Carbon steel has the characteristics of high strength and easy processing.

[0079] As an alternative, the first pad 21 is made of stainless steel. Stainless steel is characterized by high strength and corrosion resistance. As another alternative, the first pad 21 is made of aluminum alloy. Aluminum alloy is characterized by its light weight, corrosion resistance, and ease of processing. It is understood that the first pad 21 may also be made of other metallic or non-metallic materials.

[0080] Optionally, the second pad 23 is made of polyphenylene sulfide. The second pad 23 made of polyphenylene sulfide has good high temperature resistance, chemical corrosion resistance, wear resistance and sealing properties.

[0081] As an alternative, the second gasket 23 is made of polybutylene terephthalate (PET). The second gasket 23 made of PET exhibits good high-temperature resistance, chemical corrosion resistance, and sealing properties. As another alternative, the second gasket 23 is made of polypropylene (PP). The second gasket 23 made of PP exhibits good high-temperature resistance, corrosion resistance, and sealing properties. It is understood that the second gasket 23 can also be made of other materials with sealing properties.

[0082] Optionally, such as Figure 3 As shown, the sealing assembly 2 includes at least two elastic elements 22, and at least two sets of second limiting grooves 122 are provided, with the at least two elastic elements 22 and the at least two sets of second limiting grooves 122 corresponding one-to-one; each set of second limiting grooves 122 includes a second limiting groove 122 recessed on the end face of the first pad 21 near the bottom wall of the first limiting groove 121 and / or a second limiting groove 122 recessed on the bottom wall of the first limiting groove 121. This arrangement can further improve the support stability of the first pad 21 and the second pad 23, and can further improve the uniformity of force on the second pad 23.

[0083] Figure 1 An exemplary sealing assembly 2 includes two elastic members 22. Figure 3 An exemplary sealing assembly 2 includes two elastic members 22.

[0084] Optionally, the number of sealing components 2 is at least two, and the at least two sealing components 2 are distributed radially spaced along the spiral teeth 12. This further improves the reliability of the gap between the sealing spiral teeth 12 and the disc body of the other scroll plate. Figure 1 and Figure 2 As shown in this embodiment, the number of sealing components 2 on each spiral tooth 12 is exemplarily set to one.

[0085] Among them, the scroll disk is the first scroll disk, and the scroll disk body 1 of the first scroll disk can form a compression cavity with the second scroll disk. It can be understood that one of the first scroll disk and the second scroll disk is a stationary scroll disk, and the other is a moving scroll disk.

[0086] A gap is formed between the bottom wall of the first pad 21 and the first limiting groove 121. Specifically, for the case where the bottom wall of the first limiting groove 121 is not recessed with the second limiting groove 122, the bottom wall of the first limiting groove 121 is the bottom wall of the first limiting groove 121 itself. Figure 3 As shown, for the second limiting groove 122 recessed in the bottom wall of the first limiting groove 121, the bottom wall of the first limiting groove 121 includes both the bottom wall of the first limiting groove 121 itself and the inner wall of the second limiting groove 122.

[0087] Optionally, such as Figure 3As shown, the spiral tooth 12 has a first channel 123, which connects the compression chamber and the gap. This arrangement allows the fluid in the compression chamber to flow into the pressure chamber through the first channel 123 when the scroll compressor is in compression mode. The fluid flowing into the pressure chamber has a certain pressure, which increases the force applied to the first pad 21 along the axial direction of the spiral tooth 12. This, in turn, increases the force exerted by the second pad 23 against the disc body of the second scroll plate along the axial direction of the spiral tooth 12, thereby further improving the sealing effect of the second pad 23. Specifically, the fluid is either gas or liquid.

[0088] Alternatively, the number of first channels 123 is at least two, and the at least two first channels 123 are spaced apart. This can further improve the sealing effect of the second gasket 23.

[0089] It is understandable that the extension path and cross-sectional shape of the first channel 123 are not limited.

[0090] Optionally, such as Figure 3 As shown, the first gasket 21 and the second gasket 23 form a second channel 24, which connects the compression chamber and the gap. This arrangement allows fluid in the compression chamber to flow into the pressure chamber through the second channel 24 when the scroll compressor is in compression mode. This also increases the force exerted by the second gasket 23 against the second scroll plate along the axial direction of the helical teeth 12, further improving the sealing effect of the second gasket 23. Specifically, the fluid is either gas or liquid.

[0091] Alternatively, the number of second channels 24 is at least two, and the at least two second channels 24 are spaced apart. This can further improve the sealing effect of the second gasket 23.

[0092] Understandably, the extension path and cross-sectional shape of the second channel 24 are not limited.

[0093] In this embodiment, as Figure 3 As shown, the spiral tooth 12 is provided with a first channel 123, and the first pad 21 and the second pad 23 form a second channel 24. The first channel 123 is I-shaped and extends through the outer wall of the spiral tooth 12, and the extending direction of the first channel 123 is perpendicular to the axial direction of the spiral tooth 12. The second channel 24 is I-shaped and extends through the first pad 21 and the second pad 23, and the extending direction of the second channel 24 is parallel to the axial direction of the spiral tooth 12.

[0094] This utility model also provides a scroll assembly, including the scroll disk described above.

[0095] Specifically, the stationary scroll plate and / or moving scroll plate of the scroll assembly are the scroll plates described above. When the stationary scroll plate is the scroll plate described above, the second pad 23 of the stationary scroll plate abuts against the moving plate of the moving scroll plate along the axial direction of the stationary scroll plate. When the moving scroll plate is the scroll plate described above, the second pad 23 of the moving scroll plate abuts against the stationary plate of the stationary scroll plate along the axial direction of the moving scroll plate.

[0096] This technology effectively improves the sealing effect of the gap between the stationary rotary teeth and the moving disc compared to existing technologies, and also effectively improves the sealing effect of the gap between the moving rotary teeth and the stationary disc, thereby effectively improving the working performance of the compression chamber formed by the stationary and moving rotary discs.

[0097] This utility model also provides a scroll compressor, including the aforementioned scroll plate, or including the aforementioned scroll assembly. By adopting the aforementioned scroll plate or the aforementioned scroll assembly, the working performance and assembly efficiency of the scroll compressor can be effectively improved, and the production cost of the scroll compressor can be effectively reduced.
