[0050] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0051] In the description of this utility model, it should be understood that the terms "center," "length," "width," "thickness," "height," "inner," "outer," "axial," and "radial," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] The following is for reference. Figures 1-10 A scroll compressor 100 according to an embodiment of the present invention is described.

[0054] like Figure 1 As shown, the scroll compressor 100 according to an embodiment of the present invention includes: a housing 102, an electrical control component 103, a motor unit 104, a crankshaft 105, a moving scroll 110, and a stationary scroll 120. The housing 102 is provided with an electrical control chamber 1021, a low-pressure chamber 1022, and a high-pressure chamber 1023. The housing 102 is provided with an air intake 1024 communicating with the low-pressure chamber 1022, and the high-pressure chamber 1023 is provided with an air outlet 1025. The electrical control component 103 is disposed in the electrical control chamber 1021. The motor unit 104 and the crankshaft 105 are respectively disposed in the low-pressure chamber 1022. The electrical control component 103 is electrically connected to the motor unit 104 to control its operating state. The stationary scroll 120 is connected to the housing 102.

[0055] The stationary vortex plate 120 can be integrally formed with the housing 102, or the stationary vortex plate 120 and the housing 102 can be separately set and fixedly connected. The specific setting method of the stationary vortex plate 120 and the housing 102 can be determined according to the actual production requirements, and no specific limitation is made here.

[0056] When the scroll compressor 100 is running, the refrigerant enters the casing 102 through the suction port 1024 and flows into the low-pressure chamber 1022. The motor unit 104, as the power source of the scroll compressor 100, transmits power to the moving scroll 110 through the crankshaft 105, thereby driving the moving scroll 110 to rotate relative to the stationary scroll 120.

[0057] The moving scroll 110 and the stationary scroll 120 cooperate to define the compression chamber 130. Refrigerant can flow into the compression chamber 130 from the low-pressure chamber 1022. When the moving scroll 110 rotates relative to the stationary scroll 120, it compresses the refrigerant in the compression chamber 130. The stationary scroll 120 is provided with an exhaust port 121 that communicates with the compression chamber 130. The compressed refrigerant can be discharged from the compression chamber 130 into the high-pressure chamber 1023 through the exhaust port 121 on the stationary scroll 120. Furthermore, the refrigerant can be discharged from the scroll compressor 100 through the exhaust port 1025.

[0058] An electrical control cavity 1021 is provided on the side of the housing 102 away from the moving scroll 110 and the stationary scroll 120. An electrical control component 103 is disposed in the electrical control cavity 1021 and electrically connected to the motor unit 104. The electrical control component 103 can adjust the running speed of the motor unit 104 to control the compression efficiency of the scroll compressor 100 on the refrigerant.

[0059] Further integration Figure 2 and Figure 3 The moving scroll 110 includes a disk body 111 and moving scroll blades 112. The moving scroll blades 112 are disposed on the first surface 1111 of the disk body 111. The disk body 111 can serve as a mounting carrier for the moving scroll blades 112 to facilitate their installation. The side of the disk body 111 closest to the stationary scroll 120 is defined as the first surface 1111. The moving scroll blades 112 are disposed on the first surface 1111. The disk body 111 and the moving scroll blades 112 can cooperate with the stationary scroll 120 to jointly define the compression chamber 130. The crankshaft 105 is connected to the disk body 111 to drive the disk body 111 to rotate. The disk body 111 can drive the moving scroll blades 112 to rotate relative to the stationary scroll 120 to compress the refrigerant in the compression chamber 130.

[0060] Combination Figure 2 and Figure 3The moving vortex blade 112 is provided with a silencing channel 113 extending along its height direction. One end of the silencing channel 113 is open and the other end is closed to form a blind hole structure. The opening of the silencing channel 113 is located on the outer surface of the moving vortex blade 112 to communicate with the exhaust port 121.

[0061] It should be noted that the "height direction of the moving vortex blade 112" can be understood as the direction parallel to the axial direction of the moving vortex disk 110; the "outer surface of the moving vortex blade 112" refers to the surface of the moving vortex blade 112 on the side near the exhaust port 112 in its height direction.

[0062] The silencing channel 113 is open at one end near the exhaust port 121 and closed at the other end near the first surface 1111. The opening of the silencing channel 113 is located on the outer surface of the moving scroll blade 112 to facilitate communication between the silencing channel 113 and the exhaust port 121. During the compression and exhaust process of the scroll compressor 100, when the moving scroll 110 rotates to the point where the opening of the silencing channel 113 is opposite to the exhaust port 121, the opening of the silencing channel 113 can be connected to the exhaust port 121, and sound waves can enter the silencing channel 113.

[0063] Combination Figure 2 and Figure 3 Since the silencing channel 113 is formed as a blind hole structure with one end closed and the other end open, this structure has the effect of silencing noise of a specific frequency in terms of the transmission and reversal characteristics of sound waves, which is beneficial to reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0064] According to the embodiment of the present invention, the scroll compressor 100 has a silencing channel 113 provided on the moving scroll blades 112. When the silencing channel 113 is connected to the exhaust port 121, sound waves can enter the silencing channel 113, which can achieve a silencing effect, thereby reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust. Furthermore, the structure of the silencing channel 113 is simple, and there is no need to set an additional silencing device on the scroll compressor 100, which helps to simplify the structure of the scroll compressor 100 and reduce the production cost of the scroll compressor 100.

[0065] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the silencing channel 113 satisfies the following condition: h = (2n+1)*c / 4f, where h is the depth dimension of the silencing channel 113, n is a natural number (0, 1, 2, 3, 4...), c is the refrigerant sound velocity, and f is the target silencing frequency.

[0066] It should be noted that "the depth of the silencing channel 113" refers to the dimension of the silencing channel 113 extending from one end near the disc body 111 to the end with its opening.

[0067] The depth h of the silencing channel 113 is designed using the quarter-wavelength principle. When the moving scroll 110 rotates to the point where the opening of the silencing channel 113 is opposite to the exhaust port 121, the opening of the silencing channel 113 can be connected to the exhaust port 121. At this time, sound waves can enter the silencing channel 113. The silencing channel 113 can silence specific noise frequency bands (i.e., target noise-silencing bands) to reduce the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0068] Optionally, combined Figures 1 to 3 The extension direction of the silencing channel 113 is parallel to the height direction of the moving vortex blade 112.

[0069] For example, the height direction of the moving scroll blade 112 is parallel to the axial direction of the scroll compressor 100, and the silencing channel 113 can extend in a direction parallel to the axial direction of the scroll compressor 100 so that the extension direction of the silencing channel 113 is parallel to the height direction of the moving scroll blade 112, so as to facilitate the processing of the silencing channel 113, thereby improving the processing convenience of the moving scroll 110.

[0070] The extension direction of the silencing channel 113 can also be set at an angle to the height direction of the moving vortex blade 112, which is beneficial to reduce the machining accuracy of the silencing channel 113. The specific extension direction of the silencing channel 113 can be determined according to the actual production requirements, and no specific limitation is made here.

[0071] Combination Figures 1 to 3 In some embodiments of this utility model, the cross-section of the silencing channel 113 is formed as a circle, that is, the silencing channel 113 is formed as a cylindrical channel. The cylindrical channel can avoid stress concentration in the silencing channel 113 due to the presence of intersecting sidewalls, which is beneficial to improving the structural stability of the silencing channel 113, thereby improving the service life of the scroll compressor 100.

[0072] Alternatively, the cross-section of the silencing channel 113 can also be formed into an ellipse or other shapes. The specific shape of the silencing channel 113 can be determined according to actual production requirements, and no specific limitation is made here.

[0073] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the radial inner surface of the moving vortex blade 112 is provided with an outwardly recessed notch 114, and the opening of the noise reduction channel 113 is connected to the notch 114.

[0074] It should be noted that the moving vortex blade 112 extends in a spiral shape on the disk 111, and the "radial inner surface of the moving vortex blade 112" refers to the side surface of the moving vortex blade 112 that is close to the central axis of the moving vortex disk 110.

[0075] A notch 114 is provided on the side of the moving scroll blade 112 opposite to the exhaust port 121. The notch 114 is recessed radially from the side near the central axis of the moving scroll 110 toward the direction away from the central axis of the moving scroll 110. The notch 114 is used to control the design compression ratio of the scroll compressor 100. During the rotation of the moving scroll 110 relative to the stationary scroll 120, the notch 114 can be opposite to the exhaust port 121, and the notch 114 is connected to the silencing channel 113 so that sound waves can enter the silencing channel 113 through the notch 114, thereby facilitating the silencing effect of the silencing channel 113. The notch 114 can also play a silencing role, which is conducive to further reducing the fluid noise generated during the compressor and exhaust process of the scroll compressor 100.

[0076] Among them, combined Figure 4 and Figure 5 The depth of the silencing channel 113 is greater than the depth of the notch 114, which helps to ensure the effect of sound waves entering the silencing channel 113, thereby helping to ensure the silencing effect of the silencing channel 113.

[0077] In some embodiments of this utility model, the silencing channel 113 on the orthographic projection surface of the disc body 111 completely or partially overlaps with the notch groove 114 on the orthographic projection surface of the disc body 111.

[0078] Combination Figures 4 to 6 The silencing channel 113 can partially fall within the area of ​​the notch 114 projected onto the disk body 111. In other words, the silencing channel 113 can partially overlap with the notch 114 projected onto the disk body 111, which facilitates communication between the silencing channel 113 and the notch 114. This also helps to reduce the space occupied by the silencing channel 113 and the notch 114 on the moving vortex blade 112, preventing the processing of the silencing channel 113 and the notch 114 from being affected by the insufficient size of the moving vortex blade 112.

[0079] The projection surface of the silencing channel 113 on the disk body 111 can completely fall within the projection surface of the notch 114 on the disk body 111. That is, the projection surface of the silencing channel 113 on the disk body 111 can completely coincide with the projection surface of the notch 114 on the disk body 111. This facilitates the positioning and processing of the silencing channel 113 and helps to further reduce the space occupied by the silencing channel 113 and the notch 114 on the moving scroll blade, preventing the processing of the silencing channel 113 and the notch 114 from being affected by the insufficient size of the moving scroll blade 112.

[0080] In some other embodiments of this utility model, when the size of the notch 114 is small, there is enough space on the moving vortex blade 112 to process the noise reduction channel 113. In this structural state, the noise reduction channel 113 on the orthographic projection plane of the disk body 111 and the notch 114 on the orthographic projection plane of the disk body 111 may not coincide.

[0081] It is understandable that the positional relationship between the silencing channel 113 and the notch 114 can be determined according to actual production requirements, and no specific limitation is made here.

[0082] Combination Figures 4 to 6 In some embodiments of the present invention, a portion of the opening of the silencing channel 113 is located in the notch groove 114 and another portion of the opening of the silencing channel 113 extends beyond the notch groove 114.

[0083] That is, a portion of the opening of the silencing channel 113 is located inside the notch 114, and the other portion of the opening is located outside the notch 114, so that the silencing channel 113 can be connected to the notch 114. This also helps to reduce the space occupied by the silencing channel 113 and the notch 114 on the moving scroll blade 112, preventing the machining of the silencing channel 113 and the notch 114 from being affected by the insufficient size of the moving scroll blade 112. At the same time, it can prevent the silencing channel 113 from being too close to one side wall of the moving scroll blade 112 in the radial direction, which would result in insufficient strength of the silencing channel 113 and reduce the risk of damage to the silencing channel 113.

[0084] Combination Figures 8 to 10 In some embodiments of this utility model, there are multiple silencing channels 113, which are spaced apart along the length of the moving vortex blades 112.

[0085] It should be noted that the orthographic projection of the moving vortex blade 112 on the disk 111 extends in a spiral shape, and the length direction of the moving vortex blade 112 is the direction in which the moving vortex blade 112 extends in a spiral shape.

[0086] Multiple silencing channels 113 are spaced apart along the length of the moving scroll blades 112. The multiple silencing channels 113 can be connected to the exhaust port 121 at the same time, and each silencing channel 113 can play the role of silencing noise. By setting multiple silencing channels 113, the silencing effect can be effectively improved, which is conducive to further reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0087] It is understandable that the number of silencer channels 113 can be determined according to actual production requirements and the size of the moving vortex blades 112, and no specific limit is made here.

[0088] like Figure 9 As shown, in some embodiments of this utility model, at least some of the silencing channels 113 have different depths.

[0089] For example, two silencing channels 113 can be provided on the moving scroll blade 112. The depths of the two silencing channels 113 can be different so that the two silencing channels 113 can silencing different noise frequency bands respectively, thereby improving the silencing effect and further reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0090] Three silencing channels 113 can be provided on the moving scroll blade 112. Two of the three silencing channels 113 have the same depth, and the depth of the third silencing channel 113 is different from the depth of the other two silencing channels 113. This helps to reduce the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0091] It is understandable that the number of silencing channels 113 and the number of silencing channels 113 of different depths can be determined according to actual production requirements, and no specific limit is made here.

[0092] Reference Figure 9 In some embodiments of this utility model, the depth of the multiple silencing channels 113 gradually decreases in the direction away from the inner end of the moving scroll blade 112, so that the multiple silencing channels 113 can silence different noise frequency bands respectively, effectively improving the silencing effect and helping to further reduce the fluid noise generated by the scroll compressor 100 during compression and exhaust.

[0093] It should be noted that "the inner end of the moving vortex blade 112" refers to the end of the moving vortex blade 112 that is close to the central axis of the moving vortex disk 110 in its length direction.

[0094] In some other embodiments of this utility model, the depth of the multiple silencing channels 113 can be gradually increased in the direction away from the inner end of the moving vortex blade 112 to improve the silencing effect. It is understood that the specific arrangement of the silencing channels 113 can be determined according to the actual production requirements, and no specific limitation is made here, as long as the depth of the multiple silencing channels 113 is different.

[0095] like Figure 6 As shown, in some embodiments of this utility model, on the orthographic projection plane parallel to the first surface 1111, the tangent line passing through the center of the first surface 1111 and tangent to the inner end face of the moving vortex blade 112 is defined as the first connecting line L1, and the line passing through the geometric center of the silencing channel 113 and the center of the first surface 1111 is defined as the second connecting line L2. The included angle between the first connecting line L1 and the second connecting line L2 is α, and α satisfies the relationship: 50°≤α≤140°.

[0096] Combination Figure 6 and Figure 7 During the rotation of the moving scroll 110 relative to the stationary scroll 120, the swept area of ​​the exhaust port 121 relative to the moving scroll 110 is as follows: Figure 7 As shown in the circular shaded area, by ensuring that α satisfies the relationship 50°≤α≤140°, the silencing channel 113 can move within the sweeping area of ​​the exhaust port 121 during the rotation of the moving volute 110 relative to the stationary volute 120. This ensures that the silencing channel 113 can be connected to the exhaust port 121, facilitating the entry of sound waves into the silencing channel 113 and achieving the silencing effect of the silencing channel 113.

[0097] It should be noted that, referring to Figure 10 When multiple noise reduction channels 113 are provided on the moving vortex blade 112, for example, two noise reduction channels 113 can be provided on the moving vortex blade 112. The noise reduction channel 113 located closer to the inner end of the moving vortex blade 112 is defined as the first noise reduction channel a, and the noise reduction channel 113 located relatively farther from the inner end of the moving vortex blade 112 is defined as the second noise reduction channel b.

[0098] like Figure 10As shown, the line connecting the geometric center of the first silencing channel a and the center of the circle of the first surface 1111 is defined as the second line L2 of the first silencing channel a, and the angle between the first line L1 and the second line L2 of the first silencing channel a is α1. Similarly, the line connecting the geometric center of the second silencing channel b and the center of the circle of the first surface 1111 is defined as the second line L2 of the second silencing channel b, and the angle between the first line L1 and the second line L2 of the second silencing channel b is α2. α1 and α2 satisfy the relationship: 50°≤α1<α2≤140°. This ensures that during the rotation of the moving volute 110 relative to the stationary volute 120, the multiple silencing channels 113 can move within the sweeping area of ​​the exhaust port 121, thereby ensuring that the multiple silencing channels 113 can be connected to the exhaust port 121, facilitating the entry of sound waves into the silencing channels 113 and achieving the silencing effect of the silencing channels 113.

[0099] Combination Figure 6 and Figure 10 In some embodiments of the present invention, the moving vortex blade 112 includes a first part 1121 and a second part 1122. The first part 1121 is formed into an arc-shaped structure, and the side of the first part 1121 that is close to the central axis of the moving vortex disk 110 is formed as the inner end of the moving vortex blade 112. The side of the first part 1121 that is away from the inner end is connected to the second part 1122. The second part 1122 extends outward in a spiral shape.

[0100] The radial thickness of the first part 1121 is greater than the radial thickness of the second part 1122. The silencing channel 113 is disposed in the first part 1121. By making the radial thickness of the first part 1121 greater than the radial thickness of the second part 1122, the structural strength of the first part 1121 is improved, the risk of damage to the first part 1121 is reduced, and at the same time, the first part 1121 can provide sufficient processing space for the silencing channel 113, which facilitates the processing of the silencing channel 113 on the moving vortex blade 112.

[0101] Combination Figure 2 , Figure 4 and Figure 8 In some embodiments of this utility model, the second part 1122 is provided with a groove 115 for placing a seal, and the seal is in contact with the stationary vortex disk 120.

[0102] The groove 115 is provided on the side of the second part 1122 away from the first surface 1111 in the height direction, and the groove 115 is recessed towards the first surface 1111. The seal can be provided in the groove 115 so that the side of the second part 1122 away from the first surface 1111 can seal with the stationary scroll 120, thereby improving the sealing performance of the scroll compressor 100, ensuring the sealing performance of the scroll compressor 100 when compressing refrigerant, and improving the overall performance and compression efficiency of the scroll compressor 100.

[0103] like Figure 1 As shown, in some embodiments of this utility model, the housing 102 includes a support bracket 1026, which is located between the motor part 104 and the moving scroll 110. The support bracket 1026 has a recessed space 10261 that is recessed away from the moving scroll 110. The disk body 111 has a protrusion 1112 that extends into the recessed space 10261. The protrusion 1112 has an assembly groove 1113 that extends into the disk body 111. The end of the crankshaft 105 that passes through the support bracket 1026 has an eccentric sleeve 106 located in the assembly groove 1113. A mating bearing 107 is provided between the eccentric sleeve 106 and the protrusion 1112.

[0104] The support bracket 1026 has a recessed space 10261 on the side opposite to the disk body 111, which is recessed away from the moving vortex disk 110. The disk body 111 has a protrusion 1112 on the side away from the moving vortex blade 112, which protrudes towards the support bracket 1026 and extends into the recessed space 10261.

[0105] The end of the crankshaft 105 away from the motor unit 104 extends into the recessed space 10261. The side of the protrusion 1112 opposite to the crankshaft 105 is provided with a mounting groove 1113 that is recessed toward the disc body 111 and extends to the disc body 111. The end of the crankshaft 105 away from the motor unit 104 extends into the mounting groove 1113, and the end of the crankshaft 105 that extends into the mounting groove 1113 is provided with an eccentric sleeve 106. When the motor unit 104 drives the crankshaft 105 to rotate, the crankshaft 105 drives the eccentric sleeve 106 to rotate. The eccentric sleeve 106 further drives the protrusion 1112 to rotate through the mating bearing 107, thereby realizing that the motor unit 104 drives the rotating scroll 110 to rotate through the crankshaft 105.

[0106] Therefore, by designing the structure of the disc body, support bracket 1026 and crankshaft 105, it is beneficial to reduce the axial dimension of the scroll compressor 100, thereby facilitating the miniaturization design of the scroll compressor 100.

[0107] like Figure 1As shown, in some embodiments of this utility model, an exhaust valve plate 101 and a lift limiter are provided on the side of the exhaust port 121 away from the moving scroll 110. When the moving scroll 110 rotates relative to the stationary scroll 120, the refrigerant in the compression chamber 130 is continuously compressed. When the pressure in the compression chamber 130 reaches the exhaust pressure, the exhaust valve plate 101 opens the exhaust port 121, and the high-pressure refrigerant is discharged from the exhaust port 121 and can be further discharged from the scroll compressor 100.

[0108] The lift limiter can be used to limit the lift of the exhaust valve plate 101 to prevent the refrigerant from being discharged normally due to excessive opening or closing of the exhaust valve plate 101.

[0109] Reference Figure 11 The air conditioner 200 according to this utility model includes the scroll compressor 100 described above.

[0110] Since the air conditioner 200 is equipped with the aforementioned scroll compressor 100, a silencing channel 113 is provided on the moving scroll blades 112. When the silencing channel 113 is connected to the exhaust port 121, sound waves can enter the silencing channel 113, which can achieve a silencing effect, thereby reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust. Furthermore, the structure of the silencing channel 113 is simple, eliminating the need for additional silencing devices on the scroll compressor 100, which helps to simplify the structure of the scroll compressor 100 and reduce its production cost.

[0111] like Figure 12 As shown, the vehicle 300 according to this utility model includes the air conditioner 200 described above.

[0112] Since the vehicle 300 is equipped with the aforementioned scroll compressor 100 or the aforementioned air conditioner 200, by providing a silencing channel 113 on the moving scroll blades 112, when the silencing channel 113 is connected to the exhaust port 121, sound waves can enter the silencing channel 113, and the silencing channel 113 can play a silencing effect, thereby reducing the fluid noise generated by the scroll compressor 100 during compression and exhaust. Furthermore, the structure of the silencing channel 113 is simple, and there is no need to set up an additional silencing device on the scroll compressor 100, which helps to simplify the structure of the scroll compressor 100 and reduce the production cost of the scroll compressor 100.
