Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a compressor and an air conditioner. Background Art

[0002] In the related art, the air conditioner compressor uses R32 refrigerant as the refrigerant. The type of refrigerant is related to the matching dimensions of the compressor housing, cylinder, motor and crankshaft. After the refrigerant is replaced with propane refrigerant, the compressor has a larger vibration noise and higher power consumption, which greatly reduces the performance of the compressor. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present application provides a compressor.

[0005] A second aspect of the present application provides an air conditioner.

[0006] In view of this, the first aspect of the present application provides a compressor, comprising: a shell; a cylinder, arranged in the shell; a motor, arranged in the shell, and the motor is arranged at one side of the cylinder; a crankshaft, arranged in the shell, and the crankshaft is connected to the motor and the cylinder; the maximum value of the inner diameter of the shell is φ1, the outer diameter of the motor is φ2, the inner diameter of the cylinder is φ3, and the outer diameter of the part of the crankshaft located in the motor is φ4; wherein, φ2≥φ1, 0.6≥φ3 / φ1≥0.5, 40≥φ3 / φ4≥30.

[0007] A compressor provided in the present application includes a shell, a cylinder, a motor and a crankshaft.

[0008] The cylinder, motor and crankshaft are all arranged in the housing, the motor is arranged at one side of the cylinder, the crankshaft is connected to the motor, and the crankshaft is connected to the cylinder. The housing serves as a mounting carrier for the cylinder, motor and crankshaft, and has the function of mounting and fixing the cylinder, motor and crankshaft.

[0009] The refrigerant of the compressor of the present application is propane, and the matching structure of the housing, cylinder, motor and crankshaft is defined based on the propane refrigerant. Among them, the maximum value of the inner diameter of the housing is recorded as φ1, the outer diameter of the motor is recorded as φ2, the inner diameter of the cylinder is recorded as φ3, and the outer diameter of the crankshaft located inside the motor is recorded as φ4. The relationship between φ1, φ2, φ3 and φ4 is defined to satisfy φ2≥φ1, 0.6≥φ3 / φ1≥0.5, 40≥φ3 / φ4≥30.

[0010] The motor is located in the housing, and the outer diameter φ2 of the motor is greater than or equal to the maximum value φ1 of the inner diameter of the housing, that is, the motor and the housing have an interference fit, so that the motor can be firmly assembled in the housing to avoid displacement of the motor relative to the housing.

[0011] The cylinder is located in the shell, and the ratio of the inner diameter φ3 of the cylinder to the maximum inner diameter φ1 of the shell is greater than or equal to 0.5 and less than or equal to 0.6. This setting takes into account the structural rigidity of the cylinder as well as the energy efficiency and operating noise of the compressor. If the volume of the inner cavity of the cylinder is constant and the inner diameter φ3 of the cylinder is larger, the axial height of the cylinder will be reduced accordingly, which is conducive to reducing the leakage of refrigerant, improving the energy efficiency of the compressor, and reducing the operating noise of the compressor.

[0012] It can be seen that when φ3 / φ1<0.5, the axial height of the cylinder is high, which will increase the refrigerant leakage, thereby reducing the energy efficiency of the compressor and increasing the operating noise of the compressor. When φ3 / φ1>0.6, the wall thickness of the cylinder is thin, the structural strength and rigidity of the cylinder are insufficient, and the cylinder is easy to deform during operation, which will reduce the energy efficiency of the compressor and affect the performance of the compressor.

[0013] The crankshaft is connected to the motor, and the outer diameter of the crankshaft located inside the motor is recorded as φ4, that is, the motor surrounds the circumference of the crankshaft, and the outer diameter of the crankshaft surrounded by the motor is φ4. Among them, the inner diameter φ3 of the cylinder and the outer diameter φ4 of the crankshaft located inside the motor meet: 40≥φ3 / φ4≥30. This setting can reduce the friction of the crankshaft and the motor bearings while ensuring that the crankshaft effectively drives the piston movement of the cylinder, thereby ensuring the performance of the compressor.

[0014] If φ3 / φ4<30, the outer diameter of the crankshaft portion located inside the motor is too large, which increases the friction between the crankshaft and the bearing of the motor and reduces performance.

[0015] If φ3 / φ4>40, the structural rigidity of the crankshaft is insufficient, which will increase the deflection of the motor rotor and electromagnetic noise when the compressor is working.

[0016] It can be seen from this that, based on the case where the compressor uses propane refrigerant, by reasonably setting the matching structure of the shell, cylinder, motor and crankshaft, the stability and reliability of the assembly of the shell, cylinder, motor and crankshaft can be ensured, while it is beneficial to improve the energy efficiency of the compressor, reduce the operating noise of the compressor, and improve the performance of the compressor.

[0017] The compressor described above in this application may also have the following additional technical features:

[0018] In some embodiments, optionally, φ1, φ2, φ3 and φ4 satisfy: φ1+0.1mm>φ2≥φ1, 0.54≥φ3 / φ1≥0.51, 37.2≥φ3 / φ4≥34.5.

[0019] In this embodiment, the matching structure of φ1, φ2, φ3 and φ4 is further defined so that φ1, φ2, φ3 and φ4 satisfy: φ1+0.1mm>φ2≥φ1, 0.54≥φ3 / φ1≥0.51, 37.2≥φ3 / φ4≥34.5.

[0020] This setting is based on the case where the compressor uses propane refrigerant. By reasonably setting the matching structure of the shell, cylinder, motor and crankshaft, it can ensure the stability and reliability of the assembly of the shell, cylinder, motor and crankshaft, while helping to improve the energy efficiency of the compressor, reduce the operating noise of the compressor, and improve the performance of the compressor.

[0021] If φ2≥φ1+0.1mm, the interference fit between the motor and the housing will be large, which will increase the vibration noise of the compressor when it is working.

[0022] If φ2<φ1, the gap between the motor and the housing is large, the motor is easily displaced relative to the housing, and the assembly position of the motor cannot be guaranteed, which affects the normal operation of the compressor.

[0023] Illustratively, φ2=φ1+0.02mm, φ2=φ1+0.04mm, φ2=φ1+0.05mm, φ2=φ1+0.06mm and φ2=φ1+0.08mm, etc., which are not listed here one by one.

[0024] If φ3 / φ1<0.51, the axial height of the cylinder is high, which will increase the refrigerant leakage, thereby reducing the energy efficiency of the compressor and increasing the operating noise of the compressor.

[0025] If φ3 / φ1>0.54, the wall thickness of the cylinder is relatively thin, the structural strength and rigidity of the cylinder are insufficient, and the cylinder is easy to deform during operation, which will reduce the energy efficiency of the compressor and affect the performance of the compressor.

[0026] If φ3 / φ4<34.5, the outer diameter of the crankshaft portion located inside the motor is too large, which increases the friction between the crankshaft and the motor bearings and reduces performance.

[0027] If φ3 / φ4>37.2, the structural rigidity of the crankshaft is insufficient. When the compressor is working, the deflection of the motor rotor will increase, which will increase the electromagnetic noise.

[0028] In some embodiments, optionally, the axial height of the cylinder is H, where H<φ3.

[0029] In this embodiment, the structure of the cylinder is defined.

[0030] The axial height of the cylinder is H, and the inner diameter of the cylinder is φ3. H and φ3 satisfy H<φ3. This setting takes into account the structural rigidity of the cylinder and the leakage of the cylinder, which is beneficial to improving the energy efficiency of the compressor and reducing the operating noise of the compressor.

[0031] If H≥φ3, the axial height of the cylinder is too large, which will increase the refrigerant leakage, reduce the energy efficiency of the compressor, and increase the operating noise of the compressor.

[0032] In some embodiments, optionally, H and φ3 satisfy: 0.78≥H / φ3≥0.512.

[0033] In this embodiment, the relationship between H and φ3 is defined so as to satisfy 0.78≥H / φ3≥0.512.

[0034] If H / φ3<0.512, the wall thickness of the cylinder is thinner, which will reduce the structural rigidity and strength of the cylinder. When the compressor is working, the deformation of the cylinder will increase, which will reduce the energy efficiency of the compressor and affect the performance of the compressor.

[0035] If H / φ3>0.78, the axial height of the cylinder is too large, which will increase the leakage, reduce the energy efficiency of the compressor, and increase the operating noise of the compressor.

[0036] Illustratively, H / φ3=0.55, H / φ3=0.58, H / φ3=0.6, H / φ3=0.62, H / φ3=0.65, H / φ3=0.7 and H / φ3=0.75, etc., which are not listed here one by one.

[0037] In some embodiments, optionally, the cylinder is provided with a slide groove, a mounting hole, a slide and an elastic member, the slide can be slidably provided in the slide groove, the elastic member is provided in the mounting hole, and one end of the elastic member abuts against the slide; the cylinder is cross-sectioned along a direction perpendicular to the axis of the motor, and in the cross-section, the length of one end of the elastic member abutting against the slide in the first direction is φ5; wherein, 0.3≥φ5 / φ3≥0.2.

[0038] In this embodiment, the structure of the cylinder is defined.

[0039] The cylinder is provided with a sliding plate groove, a mounting hole, a sliding plate and an elastic member.

[0040] The sliding plate is slidably arranged in the sliding plate groove.

[0041] The elastic member is arranged in the mounting hole, and one end of the elastic member is in contact with the sliding sheet.

[0042] The cylinder is sectioned along a direction perpendicular to the axis of the motor. In the section, the length of one end of the elastic member abutting against the sliding plate in the first direction is φ5.

[0043] The relationship between φ5 and φ3 is limited to satisfy 0.3≥φ5 / φ3≥0.2. This setting can ensure the energy efficiency and operating noise of the compressor.

[0044] If φ5 / φ3<0.2, the vane is prone to tilt, making the gap between the vane and the vane groove uneven, which can not ensure the effective sliding of the vane, but also increase the refrigerant leakage, reduce the energy efficiency of the compressor, and increase the operating noise of the compressor.

[0045] If φ5 / φ3>0.3, the volume of the mounting hole that cooperates with the elastic part will increase, the structural rigidity and strength of the cylinder will be reduced, the deformation of the cylinder will increase when the compressor is working, the energy efficiency of the compressor will be reduced, and the performance of the compressor will be affected.

[0046] In some embodiments, optionally, φ3 and φ5 satisfy: 0.27≥φ5 / φ3≥0.21.

[0047] In this embodiment, the relationship between φ3 and φ5 is further limited to satisfy 0.27≥φ5 / φ3≥0.21, which can ensure the energy efficiency and operating noise of the compressor.

[0048] In some embodiments, optionally, the elastic member includes at least one spring, and one end of each spring abuts against the sliding sheet.

[0049] In this embodiment, the elastic member includes a spring, and one end of the spring abuts against the sliding plate.

[0050] Alternatively, the elastic member includes a plurality of springs, and one end of any of the plurality of springs abuts against the slide. This arrangement can increase the contact area and contact angle between the elastic member and the slide, ensure the balance of the force acting on the slide, ensure the running track of the slide, and avoid the slide from deflecting.

[0051] In some embodiments, optionally, when the elastic member includes multiple springs, the number of mounting holes is multiple, and each spring is provided in one mounting hole; the cylinder is cross-sectioned along a direction perpendicular to the axis of the motor, and in the cross-section, the sum of the lengths of one end of the multiple springs abutting against the sliding plate in the first direction is φ5.

[0052] In this embodiment, the structure of the elastic member is further defined.

[0053] When the elastic member includes a plurality of springs, the number of mounting holes is multiple, and each spring is arranged in one mounting hole. That is, the number of springs matches the number of mounting holes, and each spring is arranged in a corresponding mounting hole.

[0054] The cylinder is sectioned along the direction perpendicular to the axis of the motor, and in the section, the length of the end of the elastic member abutting against the sliding plate in the first direction is the sum of the lengths of the ends of the multiple springs abutting against the sliding plate in the first direction. That is, the cylinder is sectioned along the direction perpendicular to the axis of the motor, and in the section, the sum of the lengths of the ends of the multiple springs abutting against the sliding plate in the first direction is φ5.

[0055] In some embodiments, optionally, when the elastic member includes a plurality of springs, the slide plate is provided with a plurality of abutment portions, the plurality of abutment portions are spaced apart along the axial direction of the crankshaft, and each spring abuts against one abutment portion.

[0056] In this embodiment, the matching structure of the sliding sheet and the elastic member is further defined.

[0057] When the elastic member includes a plurality of springs, the sliding sheet is provided with a plurality of abutting portions.

[0058] A plurality of abutting portions are arranged at intervals in the axial direction of the crankshaft, and each spring abuts against one abutting portion.

[0059] The refrigerant of the compressor of the present application is propane, and the refrigeration capacity per unit volume of propane refrigerant is relatively low, so it is necessary to increase the volume of the cylinder, which will correspondingly increase the axial height of the cylinder, and then it is necessary to increase the size of the vane groove and the vane accordingly. By reasonably setting the matching structure of multiple springs and vanes, the vane is provided with multiple abutment parts, and the multiple abutment parts are arranged at intervals along the axial direction of the crankshaft, and each spring is matched with an abutment part, so that the contact area and contact angle between the elastic member and the vane can be increased, and the balance of the force acting on the vane can be ensured, which is conducive to ensuring the running track of the vane, avoiding the displacement of the vane, and reducing the leakage of the refrigerant, and providing a reliable structural support for improving the energy efficiency of the compressor and reducing the operating noise of the compressor.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0072] Refer to the following Figures 1 to 4 The compressor 10 and the air conditioner according to some embodiments of the present application are described.

[0073] like Figure 1 , Figure 2 and Figure 3 As shown, a compressor 10 according to some embodiments of the present application includes a housing 100 , a cylinder 200 , a motor 300 and a crankshaft 400 .

[0074] The cylinder 200 is disposed in the housing 100 .

[0075] The motor 300 is disposed in the housing 100 .

[0076] The motor 300 is arranged at one side of the cylinder 200 at an interval.

[0077] The crankshaft 400 is disposed in the housing 100 , and the crankshaft 400 is connected to the motor 300 and the cylinder 200 .

[0078] The maximum value of the inner diameter of the housing 100 is φ1.

[0079] The outer diameter of the motor 300 is φ2.

[0080] The inner diameter of the cylinder 200 is φ3.

[0081] The outer diameter of the portion of the crankshaft 400 located inside the motor 300 is φ4.

[0082] Among them, φ2≥φ1, 0.6≥φ3 / φ1≥0.5, 40≥φ3 / φ4≥30.

[0083] A compressor 10 provided in the present application includes a housing 100 , a cylinder 200 , a motor 300 and a crankshaft 400 .

[0084] The cylinder 200, the motor 300 and the crankshaft 400 are all arranged in the housing 100. The motor 300 is arranged at one side of the cylinder 200 at intervals. The crankshaft 400 is connected to the motor 300, and the crankshaft 400 is connected to the cylinder 200. The housing 100 serves as a mounting carrier for the cylinder 200, the motor 300 and the crankshaft 400, and has the function of mounting and fixing the cylinder 200, the motor 300 and the crankshaft 400.

[0085] The refrigerant of the compressor 10 of the present application is propane, and the matching structure of the housing 100, the cylinder 200, the motor 300 and the crankshaft 400 is defined based on the propane refrigerant. Among them, the maximum value of the inner diameter of the housing 100 is recorded as φ1, the outer diameter of the motor 300 is recorded as φ2, the inner diameter of the cylinder 200 is recorded as φ3, and the outer diameter of the part of the crankshaft 400 located inside the motor 300 is recorded as φ4. The relationship between φ1, φ2, φ3 and φ4 is defined so that φ2≥φ1, 0.6≥φ3 / φ1≥0.5, 40≥φ3 / φ4≥30.

[0086] The motor 300 is located in the housing 100, and the outer diameter φ2 of the motor 300 is greater than or equal to the maximum value φ1 of the inner diameter of the housing 100, that is, the motor 300 and the housing 100 have an interference fit, so that the motor 300 can be firmly assembled in the housing 100, avoiding displacement of the motor 300 relative to the housing 100.

[0087] The cylinder 200 is located in the housing 100, and the ratio of the inner diameter φ3 of the cylinder 200 to the maximum value φ1 of the inner diameter of the housing 100 is greater than or equal to 0.5 and less than or equal to 0.6. This setting takes into account the structural rigidity of the cylinder 200 and the energy efficiency and operating noise of the compressor 10. The volume of the inner cavity of the cylinder 200 is constant. If the inner diameter φ3 of the cylinder 200 is larger, the axial height of the cylinder 200 will be reduced accordingly, which is conducive to reducing the refrigerant leakage, improving the energy efficiency of the compressor 10, and reducing the operating noise of the compressor 10.

[0088] It can be seen that when φ3 / φ1<0.5, the axial height of the cylinder 200 is high, which will increase the refrigerant leakage, thereby reducing the energy efficiency of the compressor 10 and increasing the operating noise of the compressor 10. When φ3 / φ1>0.6, the wall thickness of the cylinder 200 is thin, the structural strength and rigidity of the cylinder 200 are insufficient, and the cylinder 200 is easily deformed during operation, which will reduce the energy efficiency of the compressor 10 and affect the performance of the compressor 10.

[0089] The crankshaft 400 is connected to the motor 300, and the outer diameter of the portion of the crankshaft 400 located inside the motor 300 is recorded as φ4, that is, the motor 300 surrounds the circumference of the crankshaft 400, and the outer diameter of the portion of the crankshaft 400 surrounded by the motor 300 is φ4. Among them, the inner diameter φ3 of the cylinder 200 and the outer diameter φ4 of the portion of the crankshaft 400 located inside the motor 300 satisfy: 40≥φ3 / φ4≥30. This arrangement can reduce the friction of the bearings of the crankshaft 400 and the motor 300 while ensuring that the crankshaft 400 effectively drives the piston movement of the cylinder 200, thereby ensuring the performance of the compressor 10.

[0090] If φ3 / φ4<30, the outer diameter of the portion of the crankshaft 400 located inside the motor 300 is too large, which increases the friction between the crankshaft 400 and the bearings of the motor 300 and reduces the performance.

[0091] If φ3 / φ4>40, the structural rigidity of the crankshaft 400 is insufficient, and when the compressor 10 is working, the deflection of the rotor of the motor 300 is increased, which will increase the electromagnetic noise.

[0092] It can be seen from this that, based on the case where the compressor 10 uses propane refrigerant, by reasonably arranging the matching structure of the shell 100, cylinder 200, motor 300 and crankshaft 400, it is possible to ensure the stability and reliability of the assembly of the shell 100, cylinder 200, motor 300 and crankshaft 400, while being beneficial to improving the energy efficiency of the compressor 10, reducing the operating noise of the compressor 10, and improving the performance of the compressor 10.

[0093] The present embodiment provides a compressor 10. In addition to the technical features of the above-mentioned embodiments, the present embodiment further includes the following technical features, φ1, φ2, φ3 and φ4 satisfy: φ1+0.1mm>φ2≥φ1, 0.54≥φ3 / φ1≥0.51, 37.2≥φ3 / φ4≥34.5.

[0094] In this embodiment, the matching structure of φ1, φ2, φ3 and φ4 is further defined so that φ1, φ2, φ3 and φ4 satisfy: φ1+0.1mm>φ2≥φ1, 0.54≥φ3 / φ1≥0.51, 37.2≥φ3 / φ4≥34.5.

[0095] This setting is based on the case where the compressor 10 uses propane refrigerant. By reasonably setting the matching structure of the shell 100, cylinder 200, motor 300 and crankshaft 400, it can ensure the stability and reliability of the assembly of the shell 100, cylinder 200, motor 300 and crankshaft 400, while being beneficial to improving the energy efficiency of the compressor 10, reducing the operating noise of the compressor 10, and improving the performance of the compressor 10.

[0096] If φ2 ≥ φ1 + 0.1 mm, the interference fit between the motor 300 and the housing 100 is relatively large, which may increase the vibration noise of the compressor 10 during operation.

[0097] If φ2<φ1, the gap between the motor 300 and the housing 100 is relatively large, and the motor 300 is easily displaced relative to the housing 100 , and the assembly position of the motor 300 cannot be guaranteed, which affects the normal operation of the compressor 10 .

[0098] Illustratively, φ2=φ1+0.02mm, φ2=φ1+0.04mm, φ2=φ1+0.05mm, φ2=φ1+0.06mm and φ2=φ1+0.08mm, etc., which are not listed here one by one.

[0099] If φ3 / φ1<0.51, the axial height of the cylinder 200 is relatively high, which will increase the refrigerant leakage, thereby reducing the energy efficiency of the compressor 10 and increasing the operating noise of the compressor 10.

[0100] If φ3 / φ1>0.54, the wall thickness of the cylinder 200 is relatively thin, the structural strength and rigidity of the cylinder 200 are insufficient, and the cylinder 200 is easily deformed during operation, which will reduce the energy efficiency of the compressor 10 and affect the performance of the compressor 10.

[0101] Illustratively, φ3 / φ1=0.515, φ3 / φ1=0.52, φ3 / φ1=0.525, φ3 / φ1=0.53 and φ3 / φ1=0.535, etc., which are not listed here one by one.

[0102] If φ3 / φ4<34.5, the outer diameter of the portion of the crankshaft 400 located inside the motor 300 is too large, which increases the friction between the crankshaft 400 and the bearings of the motor 300 and reduces the performance.

[0103] If φ3 / φ4>37.2, the structural rigidity of the crankshaft 400 is insufficient, and when the compressor 10 is working, the deflection of the rotor of the motor 300 will increase, which will increase the electromagnetic noise.

[0104] Illustratively, φ3 / φ4=35, φ3 / φ4=35.5, φ3 / φ4=36, φ3 / φ4=36.5 and φ3 / φ4=37, etc., which are not listed here one by one.

[0105] This embodiment provides a compressor 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features: Figure 2 As shown, the axial height of the cylinder 200 is H, where H<φ3.

[0106] In this embodiment, the structure of the cylinder 200 is defined.

[0107] The axial height of the cylinder 200 is H, and the inner diameter of the cylinder 200 is φ3. H and φ3 satisfy H<φ3. This setting takes into account both the structural rigidity of the cylinder 200 and the leakage of the cylinder 200, which is beneficial to improving the energy efficiency of the compressor 10 and reducing the operating noise of the compressor 10.

[0108] If H≥φ3, the axial height of the cylinder 200 is too large, which will increase the refrigerant leakage, reduce the energy efficiency of the compressor 10, and increase the operating noise of the compressor 10.

[0109] This embodiment provides a compressor 10. In addition to the technical features of the above embodiments, this embodiment further includes the following technical features: H and φ3 satisfy: 0.78≥H / φ3≥0.512.

[0110] In this embodiment, the relationship between H and φ3 is defined so as to satisfy 0.78≥H / φ3≥0.512.

[0111] If H / φ3<0.512, the wall thickness of the cylinder 200 is relatively thin, which will reduce the structural rigidity and strength of the cylinder 200. When the compressor 10 is working, the deformation of the cylinder 200 increases, which will reduce the energy efficiency of the compressor 10 and affect the performance of the compressor 10.

[0112] If H / φ3>0.78, the axial height of the cylinder 200 is too large, which will increase the leakage, reduce the energy efficiency of the compressor 10, and increase the operating noise of the compressor 10.

[0113] Illustratively, H / φ3=0.55, H / φ3=0.58, H / φ3=0.6, H / φ3=0.62, H / φ3=0.65, H / φ3=0.7 and H / φ3=0.75, etc., which are not listed here one by one.

[0114] This embodiment provides a compressor 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features: Figure 3 and Figure 4 As shown, the cylinder 200 is provided with a slide plate groove 210 , a mounting hole 220 , a slide plate 230 and an elastic member 240 .

[0115] The sliding plate 230 is slidably disposed in the sliding plate slot 210 .

[0116] The elastic member 240 is disposed in the mounting hole 220 , and one end of the elastic member 240 abuts against the sliding sheet 230 .

[0117] The cylinder 200 is cut into a cross section along a direction perpendicular to the axis of the motor 300 . In the cross section, the length of one end of the elastic member 240 abutting against the sliding sheet 230 in the first direction is φ5.

[0118] Among them, 0.3≥φ5 / φ3≥0.2.

[0119] In this embodiment, the structure of the cylinder 200 is defined.

[0120] The cylinder 200 is provided with a sliding plate groove 210 , a mounting hole 220 , a sliding plate 230 and an elastic member 240 .

[0121] The sliding plate 230 is slidably disposed in the sliding plate slot 210 .

[0122] The elastic member 240 is disposed in the mounting hole 220 , and one end of the elastic member 240 abuts against the sliding sheet 230 .

[0123] The cylinder 200 is cut into a cross section along a direction perpendicular to the axis of the motor 300 . In the cross section, the length of one end of the elastic member 240 abutting against the sliding sheet 230 in the first direction is φ5.

[0124] The relationship between φ5 and φ3 is defined to satisfy 0.3≥φ5 / φ3≥0.2. This setting can ensure the energy efficiency and operating noise of the compressor 10.

[0125] If φ5 / φ3<0.2, the vane 230 is prone to tilt, making the gap between the vane 230 and the vane slot 210 uneven, which can not ensure the effective sliding of the vane 230, but also increase the refrigerant leakage, reduce the energy efficiency of the compressor 10, and increase the operating noise of the compressor 10.

[0126] If φ5 / φ3>0.3, the volume of the mounting hole 220 cooperating with the elastic member 240 will increase, the structural rigidity and strength of the cylinder 200 will decrease, the deformation of the cylinder 200 will increase when the compressor 10 is working, the energy efficiency of the compressor 10 will decrease, and the performance of the compressor 10 will be affected.

[0127] The present embodiment provides a compressor 10. In addition to the technical features of the above-mentioned embodiments, the present embodiment further includes the following technical features: φ3 and φ5 satisfy: 0.27≥φ5 / φ3≥0.21.

[0128] In this embodiment, the relationship between φ3 and φ5 is further defined to satisfy 0.27≥φ5 / φ3≥0.21, so that the energy efficiency and operating noise of the compressor 10 can be guaranteed.

[0129] Illustratively, φ5 / φ3=0.22, φ5 / φ3=0.23, φ5 / φ3=0.24, φ5 / φ3=0.25 and φ5 / φ3=0.26, etc., which are not listed here one by one.

[0132] Alternatively, the elastic member 240 includes a plurality of springs 242, and one end of any spring 242 of the plurality of springs 242 abuts against the slide 230. This arrangement can increase the contact area and contact angle between the elastic member 240 and the slide 230, ensure the balance of the force acting on the slide 230, ensure the running track of the slide 230, and prevent the slide 230 from deviating.

[0133] This embodiment provides a compressor 10. In addition to the technical features of the above-mentioned embodiment, this embodiment further includes the following technical features: when the elastic member 240 includes a plurality of springs 242, the number of the mounting holes 220 is multiple.

[0134] Each spring 242 is disposed in one mounting hole 220 .

[0135] The cylinder 200 is cut into a cross section along a direction perpendicular to the axis of the motor 300 . In the cross section, the sum of the lengths of the ends of the plurality of springs 242 abutting against the sliding piece 230 in the first direction is φ5.

[0136] In this embodiment, the structure of the elastic member 240 is further defined.

[0137] When the elastic member 240 includes a plurality of springs 242, the number of the mounting holes 220 is plural, and each spring 242 is disposed in one mounting hole 220. That is, the number of the springs 242 matches the number of the mounting holes 220, and each spring 242 is disposed in one mounting hole 220 accordingly.

[0138] The cylinder 200 is cut into a cross section along a direction perpendicular to the axis of the motor 300. In the cross section, the length of the end of the elastic member 240 abutting against the slide 230 in the first direction is the sum of the lengths of the ends of the multiple springs 242 abutting against the slide 230 in the first direction. That is, the cylinder 200 is cut into a cross section along a direction perpendicular to the axis of the motor 300. In the cross section, the sum of the lengths of the ends of the multiple springs 242 abutting against the slide 230 in the first direction is φ5.

[0139] Exemplarily, when the elastic member 240 includes a spring 242 , two protrusion structures are provided on the sliding sheet 230 , and the spring 242 abuts against the two protrusion structures.

[0140] Exemplarily, when the elastic member 240 includes N springs 242 , the sliding sheet 230 is provided with N×2 protrusion structures, and each spring 242 abuts against two protrusion structures, where N is a positive integer greater than 1.

[0142] This embodiment provides a compressor 10. In addition to the technical features of the above embodiment, this embodiment further includes the following technical features: Figure 3 and Figure 4 As shown, when the elastic member 240 includes a plurality of springs 242 , the slide plate 230 is provided with a plurality of abutting portions 212 , the plurality of abutting portions 212 are arranged at intervals along the axial direction of the crankshaft 400 , and each spring 242 abuts against one abutting portion 212 .

[0143] In this embodiment, the matching structure of the sliding sheet 230 and the elastic member 240 is further defined.

[0144] When the elastic member 240 includes a plurality of springs 242 , the sliding sheet 230 is provided with a plurality of abutting portions 212 .

[0145] The plurality of abutting portions 212 are arranged at intervals in the axial direction of the crankshaft 400 , and each spring 242 abuts against one abutting portion 212 .

[0146] The refrigerant of the compressor 10 of the present application is propane, and the refrigeration capacity per unit volume of propane refrigerant is relatively low, so it is necessary to increase the volume of the cylinder 200, which will correspondingly increase the axial height of the cylinder 200, and then it is necessary to correspondingly increase the size of the vane groove 210 and the vane 230. By reasonably setting the matching structure of multiple springs 242 and the vane 230, the vane 230 is provided with multiple abutment portions 212, and the multiple abutment portions 212 are arranged at intervals along the axial direction of the crankshaft 400, and each spring 242 is matched with an abutment portion 212, so that the contact area and contact angle between the elastic member 240 and the vane 230 can be increased, and the balance of the force acting on the vane 230 can be ensured, which is conducive to ensuring the running track of the vane 230, avoiding the displacement of the vane 230, and reducing the leakage of the refrigerant, and providing a reliable structural support for improving the energy efficiency of the compressor 10 and reducing the running noise of the compressor 10.

[0147] An air conditioner according to some embodiments of the present application includes: a compressor 10 as described in any of the above embodiments.

[0148] The present application provides an air conditioner including a compressor 10 .

[0149] The compressor 10 includes a housing 100 , a cylinder 200 , a motor 300 , and a crankshaft 400 .

[0150] The cylinder 200, the motor 300 and the crankshaft 400 are all arranged in the housing 100. The motor 300 is arranged at one side of the cylinder 200 at intervals. The crankshaft 400 is connected to the motor 300, and the crankshaft 400 is connected to the cylinder 200. The housing 100 serves as a mounting carrier for the cylinder 200, the motor 300 and the crankshaft 400, and has the function of mounting and fixing the cylinder 200, the motor 300 and the crankshaft 400.

[0151] The refrigerant of the compressor 10 of the present application is propane, and the matching structure of the housing 100, the cylinder 200, the motor 300 and the crankshaft 400 is defined based on the propane refrigerant. Among them, the maximum value of the inner diameter of the housing 100 is recorded as φ1, the outer diameter of the motor 300 is recorded as φ2, the inner diameter of the cylinder 200 is recorded as φ3, and the outer diameter of the part of the crankshaft 400 located inside the motor 300 is recorded as φ4. The relationship between φ1, φ2, φ3 and φ4 is defined so that φ2≥φ1, 0.6≥φ3 / φ1≥0.5, 40≥φ3 / φ4≥30.

[0152] The motor 300 is located in the housing 100, and the outer diameter φ2 of the motor 300 is greater than or equal to the maximum value φ1 of the inner diameter of the housing 100, that is, the motor 300 and the housing 100 have an interference fit, so that the motor 300 can be firmly assembled in the housing 100, avoiding displacement of the motor 300 relative to the housing 100.

[0153] The cylinder 200 is located in the housing 100, and the ratio of the inner diameter φ3 of the cylinder 200 to the maximum value φ1 of the inner diameter of the housing 100 is greater than or equal to 0.5 and less than or equal to 0.6. This setting takes into account the structural rigidity of the cylinder 200 and the energy efficiency and operating noise of the compressor 10. The volume of the inner cavity of the cylinder 200 is constant. If the inner diameter φ3 of the cylinder 200 is larger, the axial height of the cylinder 200 will be reduced accordingly, which is conducive to reducing the refrigerant leakage, improving the energy efficiency of the compressor 10, and reducing the operating noise of the compressor 10.

[0154] It can be seen that when φ3 / φ1<0.5, the axial height of the cylinder 200 is high, which will increase the refrigerant leakage, thereby reducing the energy efficiency of the compressor 10 and increasing the operating noise of the compressor 10. When φ3 / φ1>0.6, the wall thickness of the cylinder 200 is thin, the structural strength and rigidity of the cylinder 200 are insufficient, and the cylinder 200 is easily deformed during operation, which will reduce the energy efficiency of the compressor 10 and affect the performance of the compressor 10.

[0155] The crankshaft 400 is connected to the motor 300, and the outer diameter of the portion of the crankshaft 400 located inside the motor 300 is recorded as φ4, that is, the motor 300 surrounds the circumference of the crankshaft 400, and the outer diameter of the portion of the crankshaft 400 surrounded by the motor 300 is φ4. Among them, the inner diameter φ3 of the cylinder 200 and the outer diameter φ4 of the portion of the crankshaft 400 located inside the motor 300 satisfy: 40≥φ3 / φ4≥30. This arrangement can reduce the friction of the bearings of the crankshaft 400 and the motor 300 while ensuring that the crankshaft 400 effectively drives the piston movement of the cylinder 200, thereby ensuring the performance of the compressor 10.

[0156] If φ3 / φ4<30, the outer diameter of the portion of the crankshaft 400 located inside the motor 300 is too large, which increases the friction between the crankshaft 400 and the bearings of the motor 300 and reduces the performance.

[0157] If φ3 / φ4>40, the structural rigidity of the crankshaft 400 is insufficient, and when the compressor 10 is working, the deflection of the rotor of the motor 300 is increased, which will increase the electromagnetic noise.

[0158] It can be seen from this that, based on the case where the compressor 10 uses propane refrigerant, by reasonably arranging the matching structure of the shell 100, cylinder 200, motor 300 and crankshaft 400, it is possible to ensure the stability and reliability of the assembly of the shell 100, cylinder 200, motor 300 and crankshaft 400, while being beneficial to improving the energy efficiency of the compressor 10, reducing the operating noise of the compressor 10, and improving the performance of the compressor 10.

[0159] Exemplarily, the compressor 10 includes a housing 100, a motor 300, and a compression pump body driven by the motor 300 through a rotor and a crankshaft 400 fixed in the rotor. The compression pump body includes a cylinder 200, the cylinder 200 is provided with a vane groove 210 and a vane 230 sliding in the vane groove 210, the cylinder 200 is also provided with a mounting hole 220 and an elastic member 240 in the mounting hole 220, the elastic member 240 is used to push the vane 230 to move, and the length of the end of the elastic member 240 in contact with the vane 230 in the first direction is φ5. The cylinder 200 also includes a piston that is sleeved outside the eccentric portion of the crankshaft 400 and rotates the compressor 10 gas with the crankshaft 400 at the center of the cylinder 200. The maximum value of the inner diameter of the housing 100 is φ1, the outer diameter of the motor 300 is φ2, the inner diameter of the cylinder 200 is φ3, and the outer diameter of the portion of the crankshaft 400 located in the motor 300 is φ4. Among them, φ1+0.1mm>φ2≥φ1, and 0.54≥φ3 / φ1≥0.51, and 37.2≥φ3 / φ4≥34.5.

[0160] The axial height of the cylinder 200 is H, where 0.78≥H / φ3≥0.512.

[0161] The present application reasonably arranges the matching structure of the housing 100, the cylinder 200, the motor 300 and the crankshaft 400, so that the compressor 10 has the advantages of high reliability and low vibration and noise.

[0162] The cylinder 200 is cut into a cross section along the direction perpendicular to the axis of the motor 300. In the cross section, the length of one end of the elastic member 240 abutting against the sliding plate 230 in the first direction is φ5. The elastic member 240 includes at least one spring 242. When there are multiple springs 242, the cylinder 200 is cut into a cross section along the direction perpendicular to the axis of the motor 300. In the cross section, the sum of the lengths of one end of the multiple springs 242 abutting against the sliding plate 230 in the first direction is φ5. φ3 and φ5 satisfy: 0.27≥φ5 / φ3≥0.21. This configuration enables the compressor 10 to have the advantages of high energy efficiency and low noise.
