Abstract
Description
Technical Field
[0001] This invention relates to the field of compressor technology, and in particular to a moving scroll structure and a scroll 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. However, the pressure on the upward-facing side of the moving scroll relative to the back pressure on its back is mismatched, causing the moving scroll to tilt. As the compressor speed increases, this tilt worsens, leading to increased contact load on the scroll surfaces and increased clearance, exacerbating refrigerant leakage and reducing performance. Summary of the Invention
[0003] The main objective of this invention is to propose a moving scroll disk structure and a scroll compressor, which aims to solve the problem of unbalanced forces on existing moving scroll disks, causing the moving scroll disk to tilt.
[0004] To achieve the above objectives, the present invention proposes a moving vortex disk structure, comprising:
[0005] A moving scroll plate has a first end and a second end. The first end is used to mate with a stationary scroll plate, and the second end is used to mate with a main frame. The end face of the second end has a first section, a second section, and a third section formed radially from the inside out, with the outer section surrounding the inner section. The first section corresponds to a back pressure cavity formed in the middle of the main frame, the second section corresponds to a thrust section provided on the main frame, and the third section corresponds to the periphery of the stationary scroll plate. The end face of the second end has an annular mounting groove corresponding to the second section.
[0006] A sealing ring is disposed within the annular mounting groove and is used to surround the back pressure cavity formed in the main frame.
[0007] In one embodiment, the sealing ring is concentrically arranged with the rotation center of the moving scroll disk.
[0008] In one embodiment, a raised structure is formed in the mounting groove to guide the airflow in the back pressure chamber of the main frame to the space between the bottom wall of the mounting groove and the sealing ring.
[0009] In one embodiment, a wave spring washer is provided between the bottom wall of the mounting groove and the sealing ring;
[0010] The bolstering structure includes the wave spring washer.
[0011] In one embodiment, at least one of the bottom wall of the mounting groove and the sealing ring extends a protrusion toward the other;
[0012] The raised structure includes the protrusion.
[0013] In one embodiment, the end face of the second end
[0014] Multiple pressure-guiding grooves are provided at intervals on the upper part of the mounting groove. The multiple pressure-guiding grooves are located on the outside of the mounting groove and are symmetrically arranged along the rotation center of the moving scroll disk. Each pressure-guiding groove is laterally connected to the outer periphery of the moving scroll disk.
[0015] In one embodiment, the cross-section of the pressure groove is arranged in a fan-shaped ring.
[0016] In one embodiment, the groove depth of the pressure groove is H, wherein 0.5mm≤H≤0.12mm.
[0017] Furthermore, the present invention also provides a scroll compressor, including a moving scroll disk structure, the moving scroll disk structure comprising:
[0018] A moving scroll plate has a first end and a second end. The first end is used to mate with a stationary scroll plate, and the second end is used to mate with a main frame. The end face of the second end has a first section, a second section, and a third section formed radially from the inside out, with the outer section surrounding the inner section. The first section corresponds to a back pressure cavity formed in the middle of the main frame, the second section corresponds to a thrust section provided on the main frame, and the third section corresponds to the periphery of the stationary scroll plate. The end face of the second end has an annular mounting groove corresponding to the second section.
[0019] A sealing ring is disposed within the annular mounting groove to seal around the back pressure cavity formed on the main frame.
[0020] In one embodiment, it further includes:
[0021] case;
[0022] A stationary scroll plate is fixedly installed inside the housing and is fitted with the first end of the moving scroll plate; and,
[0023] The main frame is located inside the housing and is installed in conjunction with the second end of the moving scroll plate. A thrust section is provided on the main frame.
[0024] In one embodiment, the main frame is provided with an annular boss at the second end facing the moving scroll disk, and the annular boss abuts against the second section of the moving scroll disk;
[0025] The thrust section includes the annular boss.
[0026] In one embodiment, the eccentricity of the rotating scroll disk is e, the inner diameter of the annular boss is d1, the outer diameter is d2, the inner diameter of the mounting groove is d, and the outer diameter is D, where: d > d1 + e; and / or, D <d2-e。
[0027] In the technical solution of this invention, the first end of the moving scroll disk is fitted with the stationary scroll disk to form a compression chamber, and the second end of the moving scroll disk is fitted with the main frame to form a back pressure chamber on the back of the moving scroll disk. The sealing ring is disposed in the second partition corresponding to the thrust section of the main frame to isolate the back pressure chambers in the middle and at the edge of the moving scroll disk, thus forming two back pressure chambers with different pressures. The back pressure chamber with lower pressure is located at the edge of the moving scroll disk, and the back pressure chamber with higher pressure is located in the middle of the moving scroll disk. The pressure distribution at the first end is adapted to the dynamic scroll plate. At the same time, by placing the sealing ring on the dynamic scroll plate, the sealing ring can move synchronously with the dynamic scroll plate, so that the force on the second end of the dynamic scroll plate is at the center of the dynamic scroll plate. This prevents the back pressure from generating a tilting torque on the dynamic scroll plate, keeping the force on the dynamic scroll plate balanced. This effectively reduces the tilting torque of the dynamic scroll plate, helps to reduce the contact force on the plate surface, and reduces the power consumption of the compressor. This solves the problem of unbalanced force on the existing dynamic scroll plate, which causes the dynamic scroll plate to tilt. Attached Figure Description

[0041] 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 the stationary scroll. When the scroll compressor is working, the crankshaft undergoes eccentric motion, and the moving scroll revolves, thus realizing the compressor's intake, compression, and exhaust processes. After the stationary and moving scrolls are assembled, they come into contact. During compressor operation, the surfaces of the moving and stationary scrolls press and rub against each other to achieve chamber sealing.
[0042] For scroll compressors with a high-pressure chamber structure, a sealing ring is installed on the side of the moving scroll facing away from the stationary scroll to isolate the central and peripheral back pressure chambers of the moving scroll. This confines the high-pressure area of the back pressure chamber to the central region of the moving scroll, creating back pressure chambers with different pressures. Without the sealing ring, the entire back pressure chamber of the moving scroll becomes a high-pressure area, resulting in excessive contact force between the moving and stationary scroll surfaces. This leads to severe wear on the surfaces of the moving and stationary scrolls, increasing compressor power consumption. However, existing sealing rings are usually located on the main frame, keeping the pressure distribution of the back pressure chamber on the back of the moving scroll constant. As the moving scroll revolves, the pressure in the chamber changes, causing a pressure mismatch on both sides of the moving scroll. This leads to tilting of the moving scroll, which worsens with increasing compressor speed. This tilt increases the contact load on the surface and the gap between the surfaces, exacerbating refrigerant leakage and degrading performance.
[0043] Based on this, the present invention proposes a moving scroll disk structure for scroll compressors, aiming to solve the problem of unbalanced forces on existing moving scroll disks, which causes the moving scroll disk to tilt. Specifically, Figures 1 to 4 This is a schematic diagram of the dynamic vortex disk structure provided by the present invention; Figure 5 This is a schematic diagram of an existing scroll compressor.
[0044] Please see Figures 1 to 3 In one embodiment of the present invention, the moving scroll disk structure 100 includes a moving scroll disk 1 and a sealing ring 2. The moving scroll disk 1 has a first end and a second end opposite to each other. The first end is used to cooperate with the stationary scroll disk 7 for installation, and the second end is used to cooperate with the main frame 3 for installation. The end face of the second end has a first partition 11, a second partition 12 and a third partition 13 formed sequentially from the inside to the outside in its radial direction. The partition on the outside surrounds the partition on the inside. The first partition 11 is used to correspond to the back pressure cavity formed in the middle of the main frame 3. The second partition 12 is used to correspond to the thrust part 4 provided on the main frame 3. The third partition 13 is used to correspond to the periphery of the stationary scroll disk 7. The end face of the second end is provided with an annular mounting groove 121 corresponding to the second partition 12. The sealing ring 2 is provided in the annular mounting groove 121 to seal and surround the back pressure cavity formed on the main frame 3.
[0045] In the technical solution of this invention, the first end of the moving scroll disk 1 is fitted with the stationary scroll disk 7 to form a compression chamber, and the second end of the moving scroll disk 1 is fitted with the main frame 3 to form a back pressure chamber on the back of the moving scroll disk 1. The sealing ring 2 is placed in the second partition 12 corresponding to the thrust part 4 of the main frame 3 to isolate the back pressure chambers in the middle and at the edge of the moving scroll disk 1, thereby forming two back pressure chambers with different pressures. The back pressure chamber with lower pressure is located at the edge of the moving scroll disk 1, and the back pressure chamber with higher pressure is located in the middle of the moving scroll disk 1, so as to interact with the moving scroll disk 1. The pressure distribution at the first end of the disk 1 is adapted to the pressure distribution. At the same time, by setting the sealing ring 2 on the moving scroll disk 1, the sealing ring 2 can move synchronously with the moving scroll disk 1, so that the force on the second end of the moving scroll disk 1 is at the center of the moving scroll disk 1. This prevents the back pressure from generating a tilting torque on the moving scroll disk 1, keeping the force on the moving scroll disk 1 balanced. This effectively reduces the tilting torque of the moving scroll disk 1, helps to reduce the contact force on the disk surface, and reduces the power consumption of the compressor. This solves the problem of the existing moving scroll disk 1 being unbalanced in force, which causes the moving scroll disk 1 to tilt.
[0046] It should be noted that the first end of the moving scroll plate 1 cooperates with the stationary scroll plate 7 to form a compression chamber. The first partition 11, the second partition 12, and the third partition 13 are adapted to the chamber pressure experienced by the moving scroll plate 1. The first partition 11 is the central region of the moving scroll plate 1, where the pressure is the same as the exhaust pressure, i.e., the high-pressure zone. The third partition 13 is the edge region of the moving scroll plate 1, where the pressure is between the intake and exhaust pressures, i.e., the medium-pressure zone. The second partition 12 is located between the first partition 11 and the third partition 13, i.e., the transition zone. Furthermore, the moving scroll plate 1 is subjected to the combined effects of centrifugal force, gas force, and the back pressure of the back pressure chamber. The centrifugal force is distributed radially, and the gas force is divided into tangential and radial components. However, existing sealing rings 2 are typically located on the main frame 3. Please refer to [link to relevant documentation]. Figure 5 While the pressure distribution in the back pressure chamber remains constant, the force exerted by the moving scroll 1 on it constantly changes due to its revolution. Consequently, none of these forces act on the geometric center of the moving scroll 1, resulting in a torque relative to its center and causing it to tilt. As the compressor speed increases, this tilt worsens, leading to increased contact load on the scroll surface and increased clearance, exacerbating refrigerant leakage and performance degradation. Therefore, in this embodiment, the sealing ring 2 is placed on the moving scroll 1 so that it moves synchronously with it. This ensures that the force on the second end of the moving scroll 1 is at its center, preventing the back pressure from generating a tilting torque and balancing the forces on the scroll. This effectively reduces the tilting torque, helps lower the contact force on the scroll surface, and reduces compressor power consumption, thus solving the problem of unbalanced forces causing the moving scroll 1 to tilt.
[0047] In one embodiment of the present invention, the sealing ring 2 is concentrically arranged with the rotation center of the moving scroll plate 1, so that the center of the high-pressure area defined by the sealing ring 2 is located at the center of the moving scroll plate 1, thereby reducing the tilting torque of the moving scroll plate 1.
[0048] In one embodiment of the present invention, please refer to Figure 1 and Figure 4 A raised structure 5 is formed in the mounting groove to guide the airflow in the back pressure chamber of the main frame 3 to the bottom wall of the mounting groove and the sealing ring 2. In this way, by setting the raised structure 5, the gas in the back pressure chamber in the middle of the moving scroll plate 1 is introduced into the mounting groove to press the sealing ring 2 against the end face of the thrust part 4, thereby helping to improve the sealing effect of the sealing ring 2.
[0049] It is understood that, in order to facilitate the flow of high-pressure gas into the mounting groove, in this embodiment, the inner diameter of the sealing ring 2 is larger than the inner diameter of the mounting groove, so that the sealing ring 2 and the mounting groove can be set with a gap, thereby facilitating the flow of high-pressure gas in the middle of the moving scroll plate 1 into the mounting groove.
[0050] Further, in one embodiment, please refer to Figure 4 A wave spring washer 51 is provided between the bottom wall of the mounting groove and the sealing ring 2. The shim structure 5 includes the wave spring washer 51. In this way, by providing the wave spring washer 51, an overhead space is formed between the sealing ring 2 and the bottom wall of the mounting groove, so that the high-pressure gas in the middle of the moving scroll plate 1 can enter the mounting groove to press the sealing ring 2 against the end face of the thrust part 4 of the main frame 3.
[0051] In another embodiment, at least one of the bottom wall of the mounting groove and the sealing ring 2 extends a protrusion toward the other, and the shim structure 5 includes the protrusion. Thus, by providing the protrusion, an overhead space is formed between the sealing ring 2 and the bottom wall of the mounting groove, allowing high-pressure gas in the middle of the moving scroll plate 1 to enter the mounting groove and press the sealing ring 2 against the end face of the thrust part 4 of the main frame 3.
[0052] In one embodiment of the present invention, please refer to Figure 1 As shown in the figure, a plurality of pressure-guiding grooves 6 are provided at intervals on the end face of the second end. The plurality of pressure-guiding grooves 6 are located outside the mounting groove and are symmetrically arranged along the rotation center of the moving scroll disk 1. Each pressure-guiding groove 6 is laterally connected to the outer periphery of the moving scroll disk 1. In this way, by setting the pressure-guiding grooves 6, the medium-pressure gas at the edge of the moving scroll disk 1 can enter the second partition 12, avoiding the second partition cavity from being affected by the pressure of the transition zone when it moves to the end face of the thrust part 4, so that the transition zone and the medium-pressure zone are symmetrical about the center of the moving scroll disk 1.
[0053] Furthermore, the cross-section of the pressure-applying groove 6 is arranged in a fan-shaped ring to match the shape of the moving vortex disk 1, thereby helping to increase the area of the pressure-applying groove 6.
[0054] In one embodiment of the present invention, the depth of the pressure-inducing groove 6 is H, wherein 0.5mm ≤ H ≤ 0.12mm. If the depth of the pressure-inducing groove 6 is too shallow, it will hinder the rapid flow of gas into the groove. Conversely, if the depth of the pressure-inducing groove 6 is too deep, it will reduce the thickness of the moving vortex disk 1, thereby affecting its strength. Therefore, 0.5mm ≤ H ≤ 2mm ensures that the strength of the moving vortex disk 1 is not affected, while also facilitating the rapid flow of gas into the pressure-inducing groove 6. It can be understood that the depth of the pressure-inducing groove 6 can be any value between 0.5mm and 2mm, such as 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, etc., all of which are within the protection scope of the present invention.
[0055] The present invention also proposes a scroll compressor 1000, which includes a moving scroll disk structure 100. The specific structure of the moving scroll disk structure 100 is as described in the above embodiments. Since the scroll 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.
[0056] In one embodiment of the present invention, the scroll compressor 1000 further includes a housing, a stationary scroll plate 7, and a main frame 3. The stationary scroll plate 7 is fixedly installed inside the housing and is fitted with the first end of the moving scroll plate 1. The main frame 3 is located inside the housing and is fitted with the second end of the moving scroll plate 1. A thrust part 4 is provided on the main frame 3. Thus, by setting the stationary scroll plate 7 to fit with the first end of the moving scroll plate 1, a compression chamber is formed to compress the refrigerant in the compression chamber. By setting the main frame 3 to fit with the moving scroll plate 1, a back pressure chamber is formed. At the same time, by setting the thrust part 4 to abut against the second section 12 of the moving scroll plate 1, the moving scroll plate 1 can be supported, and the sealing ring 2 can seal the gap between the moving scroll plate 1 and the thrust part 4, thereby isolating the back pressure chambers in the middle and at the edge of the moving scroll plate 1 to form two back pressure chambers with different pressures.
[0057] In one embodiment of the present invention, please refer to Figure 2 The main frame 3 is provided with an annular boss 41 at the second end facing the moving scroll plate 1. The annular boss 41 abuts against the second section 12 of the moving scroll plate 1. The thrust part 4 includes the annular boss 41. In this way, by setting the annular boss 41 to abut against the second section 12 of the moving scroll plate 1, the moving scroll plate 1 is supported and the moving scroll plate 1 is prevented from tilting.
[0058] Since the inner diameter of the installation groove is too small, the sealing ring 2 may enter the high-pressure area in the middle of the moving scroll disk 1, resulting in a mismatch between the pressure at the second end and the pressure at the first end of the moving scroll disk 1. Therefore, in this embodiment, the eccentricity of the rotation of the moving scroll disk 1 is e, the inner diameter of the annular boss 41 is d1, the outer diameter is d2, and the inner diameter of the installation groove is d, where d > d1 + e. In this way, the sealing ring 2 is prevented from entering the high-pressure area in the middle of the moving scroll disk 1, so that the pressures at both ends of the moving scroll disk 1 are adapted to each other, and the tilting moment is avoided.
[0059] Since the outer diameter of the installation groove is too small, the sealing ring 2 may enter the medium-pressure area at the edge of the moving scroll disk 1, resulting in a mismatch between the pressure at the second end and the pressure at the first end of the moving scroll disk 1. Therefore, in this embodiment, the eccentricity of the rotation of the moving scroll disk 1 is e, the inner diameter of the annular boss 41 is d1, the outer diameter is d2, and the outer diameter of the installation groove is D, where D < d2 - e. In this way, the sealing ring 2 is prevented from entering the medium-pressure area in the middle of the moving scroll disk 1, so that the pressures at both ends of the moving scroll disk 1 are adapted to each other, and the tilting moment is avoided.
[0060] It should be noted that the above two related technical features: "d > d1 + e" and "D < d2 - e" can be set alternatively or simultaneously. Obviously, setting them simultaneously has a better effect.
[0061] The above is only an exemplary embodiment of the present invention, and it does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
