Description

Technical Field

[0001] The utility model relates to the technical field of compressor equipment, in particular to a compressor and an air conditioner. Background Art

[0002] At present, the scroll compressor in the relevant technology generally includes a moving plate, a stationary plate, a crankshaft and a motor. The moving plate and the stationary plate that mesh with each other will form several pairs of compression chambers. The motor drives the crankshaft to rotate, and the eccentric part of the crankshaft drives the moving scroll to rotate in a circular motion. The several pairs of compression chambers gradually approach the center and the volume becomes smaller, realizing compression and reaching the exhaust state.

[0003] However, during the rotation of the crankshaft, the crankshaft is subjected to the driving force of the motor, radial pressure in multiple directions, and the coupling effect of temperature factors under different speeds and working conditions, which makes it easy for the crankshaft to vibrate during rotation, increasing the noise of the scroll compressor during operation. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a compressor.

[0006] A second aspect of the embodiments of the present utility model provides an air conditioner.

[0007] In view of this, according to a first aspect of an embodiment of the utility model, a compressor is provided, the compressor comprising: a shell; a compression assembly, arranged in the shell; a crankshaft, a first end of the crankshaft being connected to the compression assembly; a first frame, arranged in the shell, a second end of the crankshaft being rotatably arranged on the first frame, the first frame comprising a plurality of support plates, the plurality of support plates being arranged at intervals along the circumference of the crankshaft, at least a portion of each support plate extending radially along the crankshaft; a motor assembly, arranged between the compression assembly and the first frame, and connected to the crankshaft; wherein, at least one support plate has a cross-sectional area S1 in a direction perpendicular to the extension direction of the support plate and a cross-sectional area S2 of an inner wall of the shell, satisfying 0.014<S1 / S2<0.040.

[0008] The compressor provided by the embodiment of the utility model includes a shell, a compression assembly, a crankshaft, a first frame and a motor assembly. Specifically, the compression assembly is arranged in the shell. Optionally, the shell is provided with an exhaust chamber. The compression assembly includes a fixed scroll and a movable scroll. The fixed scroll and the movable scroll enclose a compression chamber. The fixed scroll is provided with an exhaust port, and the compression chamber can be connected to the exhaust chamber through the exhaust port.

[0009] The first end of the crankshaft is connected to the compression assembly, specifically, the first end of the crankshaft is connected to the movable scroll, and the motor assembly is connected to the crankshaft. That is, under the drive of the motor assembly, the crankshaft can drive the movable scroll to rotate linearly relative to the fixed scroll to compress the refrigerant in the compression chamber and discharge it through the exhaust port when the exhaust pressure is reached.

[0010] The second end of the crankshaft is rotatably arranged on the first frame, that is, the compression assembly and the first frame are respectively arranged on both ends of the crankshaft, that is, the first frame is a sub-frame.

[0011] The first frame includes a plurality of support plates, which are arranged at intervals along the circumference of the crankshaft, and at least a portion of each support plate extends along the radial direction of the crankshaft, thereby providing support for the crankshaft during the operation of the compressor. In addition, since the plurality of support plates are arranged at intervals, it is beneficial to ensure the reliable circulation of oil and gas in the casing during the operation of the compressor, thereby improving the reliability and stability of the operation of the compressor.

[0012] Because the crankshaft is subjected to complex forces during the operation of the compressor, it is easy to vibrate when the crankshaft rotates, causing the compressor to make loud noises during operation.

[0013] By limiting the ratio of the cross-sectional area of ​​at least one support plate in a direction perpendicular to the extension direction of the support plate to the cross-sectional area of ​​the inner wall of the shell to between 0.014 and 0.040, compared with the scroll compressor in the related art, under the premise that the cross-sectional area of ​​the inner wall of the shell remains unchanged, the cross-sectional area of ​​at least one support plate in a direction perpendicular to the extension direction of the support plate is increased, thereby effectively increasing the stiffness and structural strength of the at least one support plate, thereby increasing the overall stiffness of the first frame, improving the supporting capacity of the first frame for the crankshaft, effectively suppressing the swing of the shaft system, and significantly improving the vibration generated by the rotation of the crankshaft during the operation of the compressor, which is beneficial to reducing the noise during the operation of the compressor and improving the performance of the compressor.

[0014] Moreover, it is also helpful to reduce the manufacturing difficulty of the first frame, improve the processing economy of the first frame, and further help to reduce the production cost of the compressor.

[0015] Optionally, the shell is provided with an air intake hole, an air exhaust hole and an enthalpy increasing hole.

[0016] Optionally, the motor assembly includes a rotor and a stator, wherein the rotor is connected to the crankshaft.

[0017] Optionally, the compressor further includes a cross slip ring, a main balance block, a suction pipe and an exhaust pipe.

[0018] In addition, the compressor provided by the above technical solution of the utility model also has the following additional technical features:

[0019] In some technical schemes, optionally, each support plate includes a support arm and a connecting arm, wherein, along the radial direction of the crankshaft, the connecting arm is arranged at the end of the support arm away from the crankshaft and is connected to the inner wall of the shell; the cross-sectional area S1 of at least one support plate in a direction perpendicular to the extension direction of the support plate is the product of the thickness H of the support arm of the support plate in the axial direction of the crankshaft and the width L of the support arm in the circumferential direction of the crankshaft.

[0020] In this technical solution, it is defined that each support plate includes a support arm and a connecting arm. Specifically, along the radial direction of the crankshaft, the connecting arm is arranged at the end of the support arm away from the crankshaft, and the connecting arm is connected to the inner wall of the shell, thereby realizing the installation and fixation of the first frame, which is conducive to achieving reliable support for the crankshaft.

[0021] The cross-sectional area of ​​at least one support plate in a direction perpendicular to the extension direction of the support plate is: the product of the thickness of the support arm of the support plate in the axial direction of the crankshaft and the width of the support arm in the circumferential direction of the crankshaft, that is, S1 = H×L.

[0022] Specifically, H increases, that is, the thickness of the support arm in the axial direction of the crankshaft increases, and the cross-sectional area of ​​the support plate in the axial direction of the crankshaft can be increased. Alternatively, L increases, that is, the width of the support arm in the circumferential direction of the crankshaft increases, and the cross-sectional area of ​​the support plate in the axial direction of the crankshaft can also be increased. Alternatively, H and L increase at the same time, which can be set according to actual needs.

[0023] By increasing the cross-sectional area of ​​the support plate in the extension direction perpendicular to the support plate, the rigidity and structural strength of the support plate are effectively increased, thereby increasing the overall rigidity of the first frame, improving the supporting capacity of the first frame for the crankshaft, effectively suppressing the shaft system swing, and significantly improving the vibration generated by the rotation of the crankshaft during the operation of the compressor, which is beneficial to reducing the noise during the operation of the compressor and improving the performance of the compressor.

[0024] Optionally, the support arm and the connecting arm are an integrated structure. It can be understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the support arm and the connecting arm, achieve reliable fixation between the first frame and the shell, further enhance the support capacity of the first frame for the crankshaft, and suppress crankshaft vibration.

[0025] Optionally, the connecting arm is fixed to the inner wall of the shell by welding.

[0026] In some technical schemes, optionally, the first frame also includes a support seat, a plurality of support plates are arranged on the support seat, and along the radial direction of the crankshaft, the plurality of support plates are located between the support seat and the inner wall of the shell; wherein, the support seat is provided with a first axial hole, and the second end of the crankshaft is rotatably arranged in the first axial hole.

[0027] In this technical solution, it is defined that the first frame also includes a support seat. Specifically, a plurality of support plates are arranged on the support seat, and along the radial direction of the crankshaft, the plurality of support plates are located between the support seat and the inner wall of the shell. That is to say, one end of each support plate is connected to the support seat, and the other end of each support plate is connected to the inner wall of the shell, thereby providing reliable support for the crankshaft.

[0028] The support seat is provided with a first shaft hole, and the second end of the crankshaft extends into the first shaft hole and can rotate in the first shaft hole.

[0029] Optionally, the support seat and the multiple support plates are an integrated structure. It can be understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the support seat and the support plate, which is beneficial to further improve the overall rigidity of the first frame, thereby improving the first frame's support capacity for the crankshaft, suppressing crankshaft vibration, and reducing the operating noise of the compressor.

[0030] In addition, the integrated structure is also beneficial to the processing and production of the first frame, which is beneficial to reducing the manufacturing difficulty of the first frame, improving the processing economy of the first frame, and further beneficial to reducing the production cost of the compressor.

[0031] In some technical solutions, optionally, the outer diameter d1 of the support seat, the aperture d2 of the first axial hole and the inner diameter D of the shell satisfy 0.15<(d1-d2) / D<0.28.

[0032] In this technical solution, it can be understood that d1-d2 is twice the wall thickness of the support seat. The value range of (d1-d2) / D is between 0.15 and 0.28, that is, the ratio of twice the wall thickness of the support seat to the inner diameter of the shell is limited to between 0.15 and 0.28. Compared with the scroll compressor in the related art, the wall thickness of the support seat is increased under the premise that the inner diameter of the shell remains unchanged, thereby effectively increasing the rigidity and structural strength of the support seat, further increasing the overall rigidity of the first frame, improving the support capacity of the first frame for the crankshaft, effectively suppressing the swing of the shaft system, and significantly improving the vibration generated by the rotation of the crankshaft during the operation of the compressor, which is conducive to reducing the noise during the operation of the compressor and ensuring the energy efficiency of the compressor.

[0033] In addition, since the wall thickness of the support seat is increased, it is helpful to reduce the difficulty of manufacturing the support seat and further reduce the production cost of the compressor.

[0034] In some technical schemes, optionally, along the axial direction of the crankshaft, the crankshaft includes a first shaft section, a second shaft section and a third shaft section in sequence, the first shaft section is connected to the compression assembly, the second shaft section is connected to the motor assembly, and the third shaft section is rotatably provided on the first frame; wherein, the diameter D1 of the first shaft section, the diameter D2 of the second shaft section, the diameter D3 of the third shaft section and the inner diameter D of the shell satisfy 0.18<(D1+D2+D3) / (3D)<0.25.

[0035] In this technical solution, it is defined that the crankshaft includes a first shaft section, a second shaft section and a third shaft section. Specifically, along the axial direction of the crankshaft, the first shaft section, the second shaft section and the third shaft section are arranged in sequence, that is, the second shaft section is located between the first shaft section and the third shaft section.

[0036] The first shaft section is connected to the compression assembly, the second shaft section is connected to the motor assembly, and the third shaft section is rotatably arranged on the first frame, so that under the drive of the motor assembly, the crankshaft can drive the movable scroll to rotate relative to the fixed scroll.

[0037] The sum of the first shaft section, the second shaft section and the third shaft section divided by 3 is the average crankshaft diameter. That is to say, the ratio of the average crankshaft diameter to the casing inner diameter is limited between 0.18 and 0.25, which is beneficial to ensure that the overall stiffness, structural strength and processing economy of the crankshaft are within a better range, thereby improving the elastic and even flexural deformation of the crankshaft during the operation of the compressor, avoiding problems such as increased compressor power current and even locking due to abnormal wear of the crankshaft, and further improving the reliability and stability of the compressor operation.

[0038] Optionally, the first shaft section, the second shaft section and the third shaft section are an integrated structure, which is beneficial to further improve the overall structural strength and rigidity of the crankshaft, reduce the deformation of the crankshaft during the operation of the compressor, extend the service life of the crankshaft, reduce the probability of failure during the operation of the compressor, and help improve the energy efficiency of the compressor.

[0039] In addition, the integrated structure is also conducive to the processing and production of the crankshaft, reducing the difficulty of manufacturing the crankshaft, and thus helping to reduce the production cost of the compressor.

[0040] Optionally, the first shaft section includes an eccentric portion, and the eccentric portion is connected to the movable scroll.

[0041] In some technical solutions, optionally, the number n of support plates satisfies 2≤n≤6.

[0042] In this technical solution, the range of values ​​for the number of support plates is limited. Specifically, the number of support plates is between 2 and 6. It is understandable that if the number of support plates is too small, that is, n is less than 2, the first frame will not be able to support the crankshaft sufficiently, the overall rigidity of the first frame will be low, and the vibration generated when the crankshaft rotates will be large, resulting in high noise during the operation of the compressor. If the number of support plates is too large, that is, n is greater than 6, the gap space formed between two adjacent support plates is too small, which is not conducive to the circulation of oil and gas in the shell, affecting the reliable operation of the compressor.

[0043] By limiting the number of support plates to between 2 and 6, it is possible to ensure that the first frame provides reliable support for the crankshaft, reduce vibration and noise during compressor operation, and facilitate reliable circulation of oil and gas in the casing, thereby improving the reliability and stability of compressor operation and ensuring compressor performance.

[0044] In some technical solutions, optionally, the inner diameter D of the shell satisfies 49 mm<D<151 mm.

[0045] In this technical solution, the range of the inner diameter of the shell is limited. Specifically, the inner diameter of the shell is between 49 mm and 151 mm. It is understandable that if the inner diameter of the shell is too large, that is, greater than 151 mm, the volume of the compressor will be too large, the space occupied by the compressor will be increased, and the production cost of the compressor will be increased.

[0046] Since the housing is used to accommodate structural parts such as the compression assembly, crankshaft, motor assembly and first frame, if the inner diameter of the housing is too small, that is, less than 49 mm, it will increase the difficulty of manufacturing the compressor and affect the reliable operation of the compressor.

[0047] By limiting the inner diameter of the housing to between 49 mm and 151 mm, it is helpful to reduce the manufacturing difficulty of the compressor, and improve the processing economy of the compressor while ensuring the reliable operation of the compressor. Moreover, compared with the scroll compressor in the related art, the inner diameter of the housing is reduced to a certain extent, which is helpful to reduce the volume of the compressor, reduce the space occupied by the compressor, and help reduce the production cost of the compressor.

[0048] It can be understood that the cross-sectional area S2 of the inner wall of the shell is π(D / 2) 2 , where D is the inner diameter of the shell.

[0049] In some technical schemes, optionally, the compression assembly includes a fixed scroll and a movable scroll, wherein the fixed scroll is provided with an exhaust port, the movable scroll and the fixed scroll form a compression chamber, the compression chamber is connected to the exhaust port, and the first end of the crankshaft is connected to the movable scroll.

[0050] In this technical solution, it is defined that the compression assembly includes a fixed scroll and a movable scroll. Specifically, the fixed scroll and the movable scroll enclose a compression chamber, the fixed scroll is provided with an exhaust port, and the compression chamber is connected to the exhaust port.

[0051] The first end of the crankshaft is connected to the movable scroll. Specifically, under the drive of the motor assembly, the crankshaft can drive the movable scroll to rotate relative to the fixed scroll to compress the refrigerant in the compression chamber and discharge it through the exhaust port when the exhaust pressure is reached.

[0052] In some technical schemes, optionally, the compressor also includes a second frame, which is arranged between the movable scroll and the motor assembly and connected to the fixed scroll for supporting the movable scroll; wherein the second frame is provided with a second axial hole, and the first end of the crankshaft passes through the second axial hole and is connected to the movable scroll.

[0053] In this technical solution, it is defined that the compressor also includes a second frame. Specifically, the second frame is arranged between the movable scroll and the motor assembly. That is to say, along the axial direction of the crankshaft, the fixed scroll, the movable scroll, the second frame, the motor assembly and the first frame are arranged in sequence.

[0054] The second frame is provided with a second shaft hole. Along the axial direction of the crankshaft, the first end of the crankshaft passes through the second shaft hole and is connected with the movable scroll. It can be understood that the crankshaft can rotate relative to the second frame.

[0055] The second frame is connected to the fixed scroll, thereby providing reliable support for the movable scroll and improving the reliability and stability of the compressor operation. That is, the second frame is the main frame.

[0056] According to a second aspect of the utility model, an air conditioner is provided, comprising a compressor provided by any of the above technical solutions, thereby having all the beneficial technical effects of the compressor, which will not be repeated here.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0066] Refer to the following Figures 1 to 3 The compressor 100 and the air conditioner provided according to some embodiments of the present invention are described.

[0067] In one embodiment according to the present application, Figure 1 , Figure 2 and Figure 3 As shown, a compressor 100 is proposed, and the compressor 100 includes: a shell 110; a compression assembly 120, which is arranged in the shell 110; a crankshaft 130, and a first end of the crankshaft 130 is connected to the compression assembly 120; a first frame 140, which is arranged in the shell 110, and a second end of the crankshaft 130 is rotatably arranged in the first frame 140, and the first frame 140 includes a plurality of support plates 141, and the plurality of support plates 141 are arranged at intervals along the circumference of the crankshaft 130, and at least a portion of each support plate 141 extends along the radial direction of the crankshaft 130; a motor assembly, which is arranged between the compression assembly 120 and the first frame 140 and connected to the crankshaft 130; wherein, between a cross-sectional area S1 of at least one support plate 141 in a direction perpendicular to the extension direction of the support plate 141 and a cross-sectional area S2 of the inner wall of the shell 110, 0.014<S1 / S2<0.040 is satisfied.

[0068] The compressor 100 provided in the embodiment of the utility model includes a shell 110, a compression assembly 120, a crankshaft 130, a first frame 140 and a motor assembly. Specifically, the compression assembly 120 is arranged in the shell 110. Optionally, the shell 110 is provided with an exhaust chamber. The compression assembly 120 includes a fixed scroll 121 and a movable scroll 122. The fixed scroll 121 and the movable scroll 122 enclose a compression chamber 124. The fixed scroll 121 is provided with an exhaust port 123. The compression chamber 124 can be connected to the exhaust chamber through the exhaust port 123.

[0069] The first end of the crankshaft 130 is connected to the compression assembly 120, specifically, the first end of the crankshaft 130 is connected to the movable scroll 122, and the motor assembly is connected to the crankshaft 130. That is, under the drive of the motor assembly, the crankshaft 130 can drive the movable scroll 122 to rotate linearly relative to the fixed scroll 121 to compress the refrigerant in the compression chamber 124 and discharge it through the exhaust port 123 when the exhaust pressure is reached.

[0070] The second end of the crankshaft 130 is rotatably disposed on the first frame 140 , that is, the compression assembly 120 and the first frame 140 are respectively disposed at two ends of the crankshaft 130 , that is, the first frame 140 is a sub-frame.

[0071] The first frame 140 includes a plurality of support plates 141, which are arranged at intervals along the circumference of the crankshaft 130, and at least a portion of each support plate 141 extends along the radial direction of the crankshaft 130, thereby providing support for the crankshaft 130 during the operation of the compressor 100. In addition, since the plurality of support plates 141 are arranged at intervals, it is beneficial to ensure the reliable circulation of oil and gas in the housing 110 during the operation of the compressor 100, thereby improving the reliability and stability of the operation of the compressor 100.

[0072] Since the crankshaft 130 is subjected to complex forces during the operation of the compressor 100 , the crankshaft 130 is prone to vibration when rotating, resulting in a relatively high operating noise of the compressor 100 .

[0073] By limiting the ratio of the cross-sectional area of ​​at least one support plate 141 in a direction perpendicular to the extension direction of the support plate 141 to the cross-sectional area of ​​the inner wall of the shell 110 to between 0.014 and 0.040, compared with the scroll compressor in the related art, under the premise that the cross-sectional area of ​​the inner wall of the shell 110 remains unchanged, the cross-sectional area of ​​at least one support plate 141 in a direction perpendicular to the extension direction of the support plate 141 is increased, thereby effectively increasing the rigidity and structural strength of at least one support plate 141, thereby increasing the overall rigidity of the first frame 140, improving the supporting capacity of the first frame 140 for the crankshaft 130, effectively suppressing the shaft system swing, and significantly improving the vibration generated by the rotation of the crankshaft 130 during the operation of the compressor 100, thereby helping to reduce the noise during the operation of the compressor 100 and improve the performance of the compressor 100.

[0074] Moreover, it is also helpful to reduce the manufacturing difficulty of the first frame 140 , improve the processing economy of the first frame 140 , and further help to reduce the production cost of the compressor 100 .

[0075] Optionally, the shell 110 is provided with an air intake hole, an air exhaust hole and an enthalpy increasing hole.

[0076] Optionally, the motor assembly includes a rotor and a stator, wherein the rotor is connected to the crankshaft 130 .

[0077] Optionally, the compressor 100 further includes a cross slip ring, a main balancing block, a suction pipe and an exhaust pipe.

[0078] like Figure 1 As shown, in some embodiments, optionally, each support plate 141 includes a support arm 144 and a connecting arm 145, wherein, along the radial direction of the crankshaft 130, the connecting arm 145 is arranged at the end of the support arm 144 away from the crankshaft 130, and is connected to the inner wall of the shell 110; the cross-sectional area S1 of at least one support plate 141 in a direction perpendicular to the extension direction of the support plate 141 is the product of the thickness H of the support arm 144 of the support plate 141 in the axial direction of the crankshaft 130 and the width L of the support arm 144 in the circumferential direction of the crankshaft 130.

[0079] In this embodiment, it is defined that each support plate 141 includes a support arm 144 and a connecting arm 145. Specifically, along the radial direction of the crankshaft 130, the connecting arm 145 is arranged at the end of the support arm 144 away from the crankshaft 130, and the connecting arm 145 is connected to the inner wall of the shell 110, so as to realize the installation and fixation of the first frame 140, which is conducive to realizing reliable support for the crankshaft 130.

[0080] The cross-sectional area of ​​at least one support plate 141 in a direction perpendicular to the extension direction of the support plate 141 is: the product of the thickness of the support arm 144 of the support plate 141 in the axial direction of the crankshaft 130 and the width of the support arm 144 in the circumferential direction of the crankshaft 130, that is, S1 = H×L.

[0081] Specifically, H increases, that is, the thickness of the support arm 144 in the axial direction of the crankshaft 130 increases, and the cross-sectional area of ​​the support plate 141 in the axial direction of the crankshaft 130 can be increased. Alternatively, L increases, that is, the width of the support arm 144 in the circumferential direction of the crankshaft 130 increases, and the cross-sectional area of ​​the support plate 141 in the axial direction of the crankshaft 130 can also be increased. Alternatively, H and L increase at the same time, which can be set according to actual needs.

[0082] By increasing the cross-sectional area of ​​the support plate 141 in the extension direction perpendicular to the support plate 141, the rigidity and structural strength of the support plate 141 are effectively increased, thereby increasing the overall rigidity of the first frame 140, improving the supporting capacity of the first frame 140 for the crankshaft 130, effectively suppressing the shaft system swing, and significantly improving the vibration generated by the rotation of the crankshaft 130 during the operation of the compressor 100, thereby helping to reduce the noise during the operation of the compressor 100 and improve the performance of the compressor 100.

[0083] Optionally, the support arm 144 and the connecting arm 145 are an integrated structure. It can be understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the support arm 144 and the connecting arm 145, achieve reliable fixation between the first frame 140 and the shell 110, further enhance the supporting capacity of the first frame 140 for the crankshaft 130, and suppress the vibration of the crankshaft 130.

[0084] Optionally, the connecting arm 145 is fixed to the inner wall of the housing 110 by welding.

[0085] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the first frame 140 also includes a support seat 142, and a plurality of support plates 141 are disposed on the support seat 142. Along the radial direction of the crankshaft 130, the plurality of support plates 141 are located between the support seat 142 and the inner wall of the shell 110; wherein, the support seat 142 is provided with a first axial hole 143, and the second end of the crankshaft 130 is rotatably disposed in the first axial hole 143.

[0086] In this embodiment, it is defined that the first frame 140 also includes a support seat 142. Specifically, a plurality of support plates 141 are arranged on the support seat 142, and along the radial direction of the crankshaft 130, the plurality of support plates 141 are located between the support seat 142 and the inner wall of the shell 110. That is, one end of each support plate 141 is connected to the support seat 142, and the other end of each support plate 141 is connected to the inner wall of the shell 110, thereby providing reliable support for the crankshaft 130.

[0087] The support seat 142 is provided with a first shaft hole 143 , and the second end of the crankshaft 130 extends into the first shaft hole 143 and can rotate in the first shaft hole 143 .

[0088] Optionally, the support seat 142 and the multiple support plates 141 are an integrated structure. It can be understood that the integrated structure has good mechanical properties, and thus can improve the connection strength between the support seat 142 and the support plate 141, which is beneficial to further improve the overall rigidity of the first frame 140, thereby improving the supporting capacity of the first frame 140 for the crankshaft 130, suppressing the vibration of the crankshaft 130, and reducing the operating noise of the compressor 100.

[0089] In addition, the integrated structure is also beneficial to the processing and production of the first frame 140 , which is beneficial to reducing the manufacturing difficulty of the first frame 140 , improving the processing economy of the first frame 140 , and further beneficial to reducing the production cost of the compressor 100 .

[0090] like Figure 1 As shown, in some embodiments, optionally, the outer diameter d1 of the support seat 142, the aperture d2 of the first axial hole 143 and the inner diameter D of the housing 110 satisfy 0.15<(d1-d2) / D<0.28.

[0091] In this embodiment, it can be understood that d1-d2 is twice the wall thickness of the support seat 142. The value range of (d1-d2) / D is between 0.15 and 0.28, that is, the ratio of twice the wall thickness of the support seat 142 to the inner diameter of the housing 110 is limited to between 0.15 and 0.28. Compared with the scroll compressor in the related art, under the premise that the inner diameter of the housing 110 remains unchanged, the wall thickness of the support seat 142 is increased, thereby effectively increasing the rigidity and structural strength of the support seat 142, further increasing the overall rigidity of the first frame 140, improving the supporting capacity of the first frame 140 for the crankshaft 130, effectively suppressing the swing of the shaft system, and significantly improving the vibration generated by the rotation of the crankshaft 130 during the operation of the compressor 100, thereby helping to reduce the noise during the operation of the compressor 100 and ensure the energy efficiency of the compressor 100.

[0092] In addition, since the wall thickness of the support seat 142 is increased, it is helpful to reduce the difficulty of manufacturing the support seat 142 and further reduce the production cost of the compressor 100.

[0093] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, along the axial direction of the crankshaft 130, the crankshaft 130 includes a first shaft segment 131, a second shaft segment 132 and a third shaft segment 133 in sequence, the first shaft segment 131 is connected to the compression assembly 120, the second shaft segment 132 is connected to the motor assembly, and the third shaft segment 133 is rotatably disposed on the first frame 140; wherein, the diameter D1 of the first shaft segment 131, the diameter D2 of the second shaft segment 132, the diameter D3 of the third shaft segment 133 and the inner diameter D of the housing 110 satisfy 0.18<(D1+D2+D3) / (3D)<0.25.

[0094] In this embodiment, the crankshaft 130 is defined to include a first shaft segment 131, a second shaft segment 132 and a third shaft segment 133. Specifically, along the axial direction of the crankshaft 130, the first shaft segment 131, the second shaft segment 132 and the third shaft segment 133 are arranged in sequence, that is, the second shaft segment 132 is located between the first shaft segment 131 and the third shaft segment 133.

[0095] The first shaft section 131 is connected to the compression assembly 120, the second shaft section 132 is connected to the motor assembly, and the third shaft section 133 is rotatably disposed on the first frame 140, so that under the drive of the motor assembly, the crankshaft 130 can drive the movable scroll 122 to rotate linearly relative to the fixed scroll 121.

[0096] The sum of the first shaft section 131, the second shaft section 132 and the third shaft section 133 divided by 3 is the average value of the shaft diameter of the crankshaft 130. That is to say, the ratio of the average value of the shaft diameter of the crankshaft 130 to the inner diameter of the housing 110 is limited between 0.18 and 0.25, which is beneficial to ensure that the overall stiffness, structural strength and processing economy of the crankshaft 130 are within a better range, thereby improving the elastic and even flexural deformation of the crankshaft 130 during the operation of the compressor 100, avoiding abnormal wear of the crankshaft 130 which may lead to increased power and current of the compressor 100, or even locking, and further improving the reliability and stability of the operation of the compressor 100.

[0097] Optionally, the first shaft segment 131, the second shaft segment 132 and the third shaft segment 133 are an integrated structure, which is beneficial to further improve the overall structural strength and rigidity of the crankshaft 130, reduce the deformation of the crankshaft 130 during the operation of the compressor 100, extend the service life of the crankshaft 130, reduce the probability of failure of the compressor 100 during operation, and help improve the energy efficiency of the compressor 100.

[0098] In addition, the integrated structure is also beneficial to the processing and production of the crankshaft 130 , reducing the manufacturing difficulty of the crankshaft 130 , and further helping to reduce the production cost of the compressor 100 .

[0099] Optionally, the first shaft section 131 includes an eccentric portion, and the eccentric portion is connected to the movable scroll 122 .

[0100] In some embodiments, optionally, the number n of the support plates 141 satisfies 2≤n≤6.

[0101] In this embodiment, the value range of the number of support plates 141 is limited. Specifically, the number of support plates 141 is between 2 and 6. It is understandable that if the number of support plates 141 is too small, that is, n is less than 2, the first frame 140 will not be able to support the crankshaft 130 sufficiently, the overall rigidity of the first frame 140 will be low, and the vibration generated when the crankshaft 130 rotates will be large, resulting in a large noise during the operation of the compressor 100. If the number of support plates 141 is too large, that is, n is greater than 6, the gap space formed between two adjacent support plates 141 is too small, which is not conducive to the circulation of oil and gas in the shell 110, affecting the reliable operation of the compressor 100.

[0102] By limiting the number of support plates 141 to between 2 and 6, it is possible to ensure that the first frame 140 provides reliable support for the crankshaft 130, reduce vibration noise during operation of the compressor 100, and facilitate reliable circulation of oil and gas in the casing 110, thereby improving the reliability and stability of the operation of the compressor 100 and ensuring the performance of the compressor 100.

[0103] like Figure 1 As shown, in some embodiments, optionally, the inner diameter D of the housing 110 satisfies 49 mm<D<151 mm.

[0104] In this embodiment, the value range of the inner diameter of the housing 110 is limited. Specifically, the inner diameter of the housing 110 is between 49 mm and 151 mm. It is understandable that if the inner diameter of the housing 110 is too large, that is, greater than 151 mm, the volume of the compressor 100 will be too large, the occupied space of the compressor 100 will be increased, and the production cost of the compressor 100 will be increased.

[0105] Since the shell 110 is used to accommodate structural parts such as the compression assembly 120, the crankshaft 130, the motor assembly and the first frame 140, if the inner diameter of the shell 110 is too small, that is, less than 49 mm, it will increase the manufacturing difficulty of the compressor 100 and affect the reliable operation of the compressor 100.

[0106] By limiting the inner diameter of the housing 110 to between 49 mm and 151 mm, it is helpful to reduce the manufacturing difficulty of the compressor 100, and improve the processing economy of the compressor 100 while ensuring the reliable operation of the compressor 100. Moreover, compared with the scroll compressor in the related art, the inner diameter of the housing 110 is reduced to a certain extent, which is helpful to reduce the volume of the compressor 100, reduce the occupied space of the compressor 100, and help reduce the production cost of the compressor 100.

[0107] It is understandable that the cross-sectional area S2 of the inner wall of the housing 110 is π(D / 2) 2 , where D is the inner diameter of the shell 110.

[0108] like Figure 3 As shown, in some embodiments, optionally, the compression assembly 120 includes a fixed scroll 121 and a movable scroll 122, wherein the fixed scroll 121 is provided with an exhaust port 123, the movable scroll 122 and the fixed scroll 121 are enclosed to form a compression chamber 124, the compression chamber 124 is connected to the exhaust port 123, and the first end of the crankshaft 130 is connected to the movable scroll 122.

[0109] In this embodiment, the compression assembly 120 is defined to include a fixed scroll 121 and a movable scroll 122 . Specifically, the fixed scroll 121 and the movable scroll 122 enclose a compression chamber 124 . The fixed scroll 121 is provided with an exhaust port 123 . The compression chamber 124 is connected to the exhaust port 123 .

[0110] The first end of the crankshaft 130 is connected to the movable scroll 122. Specifically, under the drive of the motor assembly, the crankshaft 130 can drive the movable scroll 122 to rotate relative to the fixed scroll 121 to compress the refrigerant in the compression chamber 124 and discharge it through the exhaust port 123 when the exhaust pressure is reached.

[0111] like Figure 3 As shown, in some embodiments, optionally, the compressor 100 also includes a second frame 160, which is arranged between the movable scroll 122 and the motor assembly and connected to the fixed scroll 121 for supporting the movable scroll 122; wherein the second frame 160 is provided with a second axial hole 161, and the first end of the crankshaft 130 is connected to the movable scroll 122 through the second axial hole 161.

[0112] In this embodiment, it is defined that the compressor 100 also includes a second frame 160. Specifically, the second frame 160 is arranged between the movable scroll 122 and the motor assembly. That is, along the axial direction of the crankshaft 130, the fixed scroll 121, the movable scroll 122, the second frame 160, the motor assembly and the first frame 140 are arranged in sequence.

[0113] The second frame 160 is provided with a second shaft hole 161 , and along the axial direction of the crankshaft 130 , the first end of the crankshaft 130 passes through the second shaft hole 161 to connect with the movable scroll 122 . It can be understood that the crankshaft 130 can rotate relative to the second frame 160 .

[0114] The second frame 160 is connected to the fixed scroll 121, thereby providing reliable support for the movable scroll 122, and improving the reliability and stability of the operation of the compressor 100. That is, the second frame 160 is a main frame.

[0115] According to a second aspect of the utility model, an air conditioner is provided, comprising a compressor 100 as provided in any of the above embodiments, and thus having all the beneficial technical effects of the compressor 100, which will not be described in detail herein.
