Description

Technical Field

[0001] This invention belongs to the field of air conditioning design technology, specifically relating to a motor stator assembly, a compressor and its assembly method, and an air conditioner. Background Technology

[0002] With industry development, air conditioner evaporators and condensers are becoming smaller, and the operating frequency of variable frequency rotary compressors is constantly increasing. High-speed compressors are one of the main development directions for the future industry, and the stator structure design is a key factor affecting the stable and efficient operation of high-speed compressors. Currently, relatively mature variable frequency compressor stator structures include... Figure 1 As shown, the stator yoke cut edge contacts the compressor housing. The stator is fixed to the housing by means of interference fit or laser welding. Several gaps are reserved in the contact area between the stator yoke cut edge and the housing as flow channels for refrigerant and refrigeration oil to pass through.

[0003] As the operating frequency of high-speed compressors increases, the electromagnetic force also increases. The stator tangent (i.e., the outer circle of the stator core) directly contacts the housing, causing the high-frequency vibration of the stator to be directly transmitted to the housing, resulting in significant outward noise radiation or resonance in other parts of the compressor, leading to loud vibration noise. Summary of the Invention

[0004] Therefore, the present invention provides a motor stator assembly, a compressor and its assembly method, and an air conditioner, which can overcome the shortcomings of related technologies where the cut edge of the motor stator core directly contacts the housing, causing the high-frequency vibration of the stator to be directly transmitted to the housing, resulting in large outward radiation noise or causing resonance in other parts of the compressor, leading to large vibration noise.

[0005] To address the aforementioned problems, the present invention provides a motor stator assembly, comprising a stator core and a support member. A limiting groove is formed on the outer circular wall surface of the stator core. The support member has a limiting portion that is accommodated within the limiting groove. A filling gap exists between the limiting portion and the limiting groove, and the filling gap is filled with a damping layer. The support member also has a connecting portion for fixed connection with an assembly object.

[0006] In some embodiments, there are multiple limiting grooves, each of which is evenly spaced along the circumferential direction of the stator core. There are multiple support members, each corresponding to one of the limiting grooves, and the connecting portion protrudes from the outer circular wall of the stator core.

[0007] In some embodiments, each of the limiting grooves is a constricted groove and is projected axially onto the stator core, and the shape of each limiting part matches the shape of each constricted groove.

[0008] In some embodiments, each of the limiting grooves is disposed at the yoke ring corresponding to the radial outer side of the stator tooth of the stator core corresponding to its position, and the limiting groove is symmetrical about the tooth symmetry line of the stator tooth.

[0009] In some embodiments, the number of limiting grooves is n, the number of stator teeth is N, 3≤n≤N, and n is a factor of N or an integer multiple of the factor; and / or, the radial thickness of the yoke is L1, and the maximum groove depth of the limiting groove is L2, 0.5L1≤L2≤0.85L1.

[0010] In some embodiments, the circumferential width of the stator teeth is d1, and the maximum groove width of the limiting groove is d2, where 0.5d1≤d2≤0.85d1.

[0011] In some embodiments, the thickness of the filling gap is s, where 0.05d2≤s≤0.2d2.

[0012] In some embodiments, the motor stator assembly further includes a collar fitted on the radially outer side of the stator core, and the connecting portion of each of the supports is fixedly connected to the inner ring surface of the collar.

[0013] In some embodiments, the limiting groove extends along the axial direction of the stator core and is referenced to the vertical orientation of the stator core, with the top of the limiting groove being a blind end.

[0014] The present invention also provides a compressor, including a compressor housing and the above-described motor stator assembly, wherein the connecting portion of the support member is fixedly connected to the compressor housing; or, when the motor stator assembly includes a collar, the outer ring surface of the collar is fixedly connected to the compressor housing.

[0015] The present invention also provides an assembly method for a compressor as described above, comprising the following steps: The limiting part of the support is inserted into the limiting groove to form the filling gap, and the damping material is filled into the filling gap to form the damping layer by injection molding, thereby preparing the motor stator assembly. The prepared motor stator assembly is fixed inside the compressor housing via the connecting part of the support member.

[0016] In some embodiments, when the motor stator assembly includes a collar, after the damping layer is formed, the collar is fitted onto the radially outer end of the connecting portion of the support member and the radially outer end of the connecting portion is fixedly connected to the inner ring surface of the collar to prepare the motor stator assembly. Then, the prepared motor stator assembly is fixed to the inner wall surface of the compressor housing via the collar.

[0017] The present invention also provides an air conditioner, including the compressor described above.

[0018] The motor stator assembly, compressor, assembly method thereof, and air conditioner provided by this invention have the following beneficial effects: By setting a support and a damping layer between the stator core and the assembly object, wherein the damping layer is filled between the limiting groove of the stator core and the limiting part of the support, a flexible suspension support structure for the stator core is realized through the support of the assembly object. In this way, the stator core and the assembly object do not directly contact each other. The vibration of the stator core during operation is greatly reduced after being transmitted to the support through the damping layer, and then transmitted to the assembly object through the support. This can significantly reduce the vibration transmission to the assembly object and reduce the vibration noise level. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90° or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0026] See also Figures 1 to 11 As shown, according to an embodiment of the present invention, a motor stator assembly is provided, including a stator core 1. It is understood that the aforementioned stator core 1 includes a yoke ring 12 and a plurality of stator teeth 11 evenly spaced circumferentially on the inner ring wall of the yoke ring 12. A stator slot (not shown in the figure) is formed between two adjacent stator teeth 11. A stator winding (not shown in the figure) is also wound around each stator tooth 11. Of course, the motor stator assembly should also have a corresponding insulating frame. As a conventional technical means in the art, the present invention does not protect it and therefore will not elaborate on it. The motor stator assembly also includes a support member 2. A limiting groove 10 is formed on the outer circular wall of the stator core 1. The support member 2 has a limiting part 21 that is accommodated in the limiting groove 10. There is a filling gap (not shown in the figure) between the limiting part 21 and the limiting groove 10. The filling gap is filled with a damping layer 3. The support member 2 also has a connecting part 22, which is used to fix and connect with the assembled object (e.g., welding or interference fit). The aforementioned damping layer 3 can be made of epoxy resin or silicone gel, which have good reliability and good damping and vibration reduction performance, and can be, for example, a motor housing or a compressor housing, depending on the actual working conditions. The aforementioned support member 2 is preferably made of a metal material with sufficient rigidity.

[0027] In this technical solution, by setting a support member 2 and a damping layer 3 between the stator core 1 and the assembly object, wherein the damping layer 3 is filled between the limiting groove 10 of the stator core 1 and the limiting part 21 of the support member 2, a flexible suspension support structure for the stator core 1 is realized through the support member 2 for the assembly object. In this way, the stator core 1 and the assembly object do not directly contact each other. The vibration of the stator core 1 during operation is greatly reduced after being transmitted to the support member 2 through the damping layer 3, and then transmitted to the assembly object through the support member 2. This can significantly reduce the vibration transmission to the assembly object and reduce the vibration noise level.

[0028] In some embodiments, there are multiple limiting grooves 10, each of which is evenly spaced along the circumferential direction of the stator core 1. There are multiple support members 2, which are arranged in a one-to-one correspondence with each of the limiting grooves 10. The connecting part 22 protrudes from the outer circular wall surface of the stator core 1.

[0029] See details Figure 2 As shown, each of the limiting grooves 10 is inserted into each of the support members 2 in a one-to-one manner, and is evenly spaced around the central axis of the stator core 1. This can further reduce the transmission path of the vibration of the stator core 1 to the assembly object (such as the compressor housing) through the damping layer 3 and the support members 2, thereby improving the vibration reduction and noise reduction effect.

[0030] More importantly, in this technical solution, since the connecting part 22 protrudes from the outer circular wall of the stator core 1, a fan-shaped flow groove 5 will be formed between two adjacent support members 2. This allows the upper and lower cavities of the motor stator assembly (i.e., the upper and lower cavities of the motor, see...) to... Figure 7 As shown, the number of flow channels 5 can be adjusted by using the number of support members 2, thereby ensuring that the flow channels 5 have a large flow area. In a specific embodiment, the total cross-sectional area (i.e., the total flow area) of the aforementioned flow channels 5 in this invention is 10% to 20% of the inner circular cross-sectional area of ​​the compressor housing, which is much larger than that of conventional technologies (such as...). Figure 1 The 3% to 5% reduction (as shown in the figure) significantly reduces the refrigerant flow resistance and refrigeration oil return resistance inside the compressor, thereby greatly optimizing the compressor's energy efficiency and oil return.

[0031] In addition, the size of the gap between the outer circular wall of the stator core 1 and the inner wall of the assembled object, such as the compressor housing, can be adjusted by the radial height of the connecting part 22 protruding from the outer circular wall of the stator core 1, thereby further increasing the flow area of ​​each flow groove 5.

[0032] Given a fixed inner diameter of the compressor housing, the connecting portions 22 of the aforementioned support members 2 are preferably fixedly connected to the inner wall of the compressor housing by welding. This reduces the area occupied by the connecting portions 22 in the flow channel 5. It is understood that when the connecting portions 22 of the support members 2 are fixedly connected to the compressor housing by an interference fit, the assembly area between the connecting portions 22 and the compressor housing needs to be sufficiently large to ensure a reliable connection. An excessively large area will encroach on the flow area of ​​the flow channel 5. Furthermore, the shape of the radially outer end face of the aforementioned connecting portion 22 should match the shape of the inner wall of the compressor housing.

[0033] The shape of the aforementioned limiting groove 10 can be varied, such as... Figure 5 The rectangular shape shown is simple in structure and easy to manufacture. However, due to the lack of necessary radial limiting, corresponding limiting fixtures are required when assembling the support 2 and the limiting groove 10. This makes the assembly process relatively complex during manufacturing. As a preferred embodiment, each limiting groove 10 is a constricted groove, such as... Figure 4 The constricted groove shown has an arc-shaped groove portion or Figure 6 The T-shaped constriction groove shown is projected onto the axial direction of the stator core 1. The shape of each limiting part 21 matches the shape of each constriction groove. That is, when the limiting groove 10 is a constriction groove with an arc groove, the shape of the aforementioned limiting part 21 also has a circular head. When the limiting groove 10 is a T-shaped constriction groove, the shape of the aforementioned limiting part 21 also has a T-shaped head.

[0034] In this technical solution, each limiting groove 10 is designed as a constricted groove, and the shape of each limiting part 21 matches the constricted groove. This ensures the stability of the relative position of the support member 2 and the stator core 1 by inserting the limiting part 21 of each support member 2 into the limiting groove 10. Only the size and uniformity of the filling gap between each limiting part 21 and the limiting groove 10 need to be adjusted, simplifying the assembly.

[0035] The aforementioned limiting grooves 10 are preferably constricted grooves with arc-shaped groove portions, which have relatively smooth groove walls, reducing magnetic leakage while also reducing stress concentration in the stator core 1.

[0036] In some embodiments, each of the limiting grooves 10 is disposed at the yoke 12 corresponding to the radial outer side of the stator tooth 11 of the stator core 1, and the limiting groove 10 is symmetrical about the tooth symmetry line of the stator tooth 11.

[0037] See details Figure 4As shown, each limiting groove 10 is provided on the back side of each stator tooth 11, which can minimize the adverse effects of opening the limiting groove 10 on the magnetic circuit in the stator core 1, and at the same time, can also reduce the adverse effects on the structural strength of the yoke ring 12.

[0038] In some embodiments, the number of limiting grooves 10 is n, and the number of stator teeth 11 is N, where 3 ≤ n ≤ N, and n is a factor of N or an integer multiple of the factor. For example, a 9-slot stator has 9 stator teeth 11, and the number of limiting grooves 10 can be 3, 6, or 9; a 12-slot stator has 12 stator teeth 11, and the number of limiting grooves 10 can be 3, 4, 6, 8, 9, or 12; a 15-slot stator has 15 stator teeth 11, and the number of limiting grooves 10 can be 3, 5, 6, 9, 10, 12, or 15. In a specific embodiment of the present invention, the stator core 1 has 12 stator teeth 11 and 6 limiting grooves 10.

[0039] In this technical solution, the number of limiting grooves 10 is designed to be no more than the number of stator teeth 11 of the stator core 1 and no less than 3, and is a factor or an integer multiple of the number of stator teeth 11, which can ensure the centering and balanced support of the stator core 1.

[0040] See details Figure 4 As shown, in some embodiments, the radial thickness of the yoke 12 is L1, the maximum groove depth of the limiting groove 10 is L2, and 0.5L1≤L2≤0.85L1; the circumferential width of the stator tooth 11 is d1, and the maximum groove width of the limiting groove 10 is d2, and 0.5d1≤d2≤0.85d1.

[0041] In this technical solution, the maximum groove depth and maximum groove width of each limiting groove 10 are limited, which can ensure the structural strength of the stator core 1 and prevent fatigue damage to the stator core 1 during operation.

[0042] In some embodiments, the thickness of the filling gap is s, where 0.05d2≤s≤0.2d2.

[0043] In this technical solution, the thickness of the filling gap of the damping layer 3 is limited to prevent the damping and vibration reduction effect from being poor due to the thickness being too small, and the support strength of the support member 2 to the stator core 1 from being insufficient and thus causing instability.

[0044] In some embodiments, the motor stator assembly further includes a collar 4, which is fitted onto the radial outer side of the stator core 1, and the connecting portion 22 of each support member 2 is fixedly connected to the inner ring surface of the collar 4, for example by welding or interference fit.

[0045] In this technical solution, a collar 4 is further provided on the radial outer side of each support member 2, which can connect each support member 2 into an organic whole, thus facilitating the assembly of the motor stator assembly with the aforementioned assembly object (such as the compressor housing).

[0046] In some embodiments, the limiting groove 10 extends along the axial direction of the stator core 1, and with the axial direction of the stator core 1 in the vertical direction as a reference, the top of the limiting groove 10 is a blind end, that is, the aforementioned limiting groove 10 does not extend to the top side end face of the stator core 1.

[0047] In this technical solution, the top of the limiting groove 10 is a blind end, which can form an axial mechanical limit on the limiting part 21 of the aforementioned support member 2, preventing the stator core 1 from detaching due to excessive vibration during operation, which generates a large axial component force that overcomes the adhesive force of the damping layer 3 between the limiting groove 10 and the aforementioned limiting part 21.

[0048] To further enhance the connection strength between the damping layer 3 and the stator core 1 and the support member 2, in a preferred embodiment, a plurality of recesses (not shown in the figure) are formed on the outer surface of the aforementioned limiting part 21. This allows a portion of the damping layer 3 to be accommodated in each recess, thereby enhancing the connection strength between the damping layer 3 and the limiting part 21. It is understood that since the stator core 1 is mostly formed by lamination, the damping layer 3 and the lamination joint can form a stepped engagement, thus also achieving a high connection strength.

[0049] According to an embodiment of the present invention, a compressor is also provided, including a compressor housing and the above-described motor stator assembly, wherein the connecting portion 22 of the support member 2 is fixedly connected to the compressor housing, that is, the aforementioned assembly object is also the compressor housing; or, when the motor stator assembly includes a collar 4, the outer ring surface of the collar 4 is fixedly connected to the compressor housing, and the aforementioned fixed connection is, for example, a welding or interference fit connection.

[0050] When the compressor is running, the vibration of the stator core 1 is significantly reduced after being transmitted to the support component 2 through the damping layer 3, and then transmitted to the compressor casing through the support component 2. This results in a significant reduction in the compressor's noise and vibration levels, with the effect becoming more pronounced at higher operating frequencies (noise optimization effect as shown in...). Figure 10 As shown); the flow path channel (i.e., the flow groove 5 mentioned above) between the outer circular wall of the stator core 1 and the compressor housing has a much larger area than that of a conventional stator structure compressor, and the compressor's energy efficiency and oil return are also greatly optimized (the energy efficiency optimization effect is as shown in the figure). Figure 11 (As shown).

[0051] According to an embodiment of the present invention, an assembly method for a compressor as described above is also provided, comprising the following steps: The stator winding is wound on each stator tooth 11 of the stator core 1. Then, the limiting part 21 of the support member 2 is inserted into the limiting groove 10 to form the filling gap. The damping material is filled into the filling gap to form the damping layer 3 by injection molding, thus preparing the motor stator assembly. The damping layer 3 is formed by filling, which can ensure the reliable bonding between the damping layer 3 and the support member 2 and the stator core 1. When the limiting groove 10 has a blind end, the damping material is also filled in the gap between the end face of the support member 2 and the blind end of the limiting groove 10, which further improves the reliable connection between the support member 2 and the stator core 1. The prepared motor stator assembly is fixed inside the compressor housing via the connecting part 22 of the support member 2.

[0052] In some embodiments, when the motor stator assembly includes a collar 4, after the damping layer 3 is formed, the collar 4 is fitted onto the radially outer end of the connecting portion 22 of the support member 2 and the radially outer end of the connecting portion 22 is fixedly connected to the inner ring surface of the collar 4 to prepare the motor stator assembly. Then, the prepared motor stator assembly is fixed to the inner wall surface of the compressor housing via the collar 4.

[0053] According to an embodiment of the present invention, an air conditioner is also provided, including the compressor described above.

[0054] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
