Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, such as a compressor and refrigeration equipment. Background Technology

[0002] A compressor includes a housing and a stator and a rotor housed within the housing. It operates and performs work through electromagnetic induction between the stator and the rotor. The stator is typically fixed to the housing using a heat-shrink fitting process, allowing for a tight interference fit between the stator and the housing.

[0003] However, the heat-shrink assembly method results in a large contact area between the inner wall of the housing and the outer wall of the stator. Because different parts of the housing cool at different rates after heating, the stator may also deform differently, affecting motor efficiency and noise. To address this issue, related technologies provide a compressor including a housing, a stator, and at least one support structure. The support structure is connected to the stator and fixedly connected to the housing, creating a gap between the outer peripheral wall of the stator and the inner peripheral wall of the housing. This prevents direct contact between the stator and the housing, reducing vibration transmission between them and thus decreasing noise generated by housing vibration.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Because the wiring angles of the power cords and compressor cover terminals differ between different devices, compressors of the same specification and model may have multiple different cover assembly angles. Furthermore, due to the wiring limitations between the stator leads and the cover terminals, the angle between the root of the stator lead and the cover terminal is within a fixed range. Therefore, the assembly angle of the stator leads needs to be adjusted to match the assembly angle of the cover. In some compressors, the stator angle cannot be adjusted after assembly with the housing, making it impossible to adjust the root angle of the stator leads. During compressor production and assembly, different stator assembly fixtures with varying angles are used, increasing assembly costs and time, thus impacting production efficiency.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a compressor and refrigeration equipment that allows the stator inside the compressor to be adjusted to a set angle, thereby adjusting the root angle of the stator lead wires, reducing the corresponding assembly cost and time cost, and thus improving production efficiency.

[0009] In some embodiments, the compressor includes a housing, a stator, and a limiting device. The housing has a first groove on its inner sidewall along its circumferential direction. The stator is rotatably disposed within the housing via a rotating assembly. One or more second grooves are circumferentially disposed on the outer sidewall of the stator along its vertical direction, and the first groove surrounds the second groove. The limiting device includes a limiting portion movably disposed within the first groove. When the stator rotates to a set position, the limiting portion of the limiting device is moved to the intersection of the first and second grooves, causing the end of the limiting portion to insert into the second groove, thereby fixing the limiting portion to fix the stator.

[0010] In some embodiments, the limiting part includes a movable seat and an elastic limiting member. The movable seat is movably disposed in the first groove; the elastic limiting member is disposed on the movable seat, and when the stator rotates to a set position, the movable seat is moved to the intersection of the first groove and the second groove, and the end of the elastic limiting member is inserted into the second groove.

[0011] In some embodiments, the movable base is provided with a mounting groove, and an elastic limiting member is disposed within the mounting groove. The elastic limiting member includes an elastic element and a locking block. The first end of the elastic element is fixedly connected to the bottom of the mounting groove; the locking block is fixedly connected to the second end of the elastic element. Through the elastic force of the elastic element, the locking block can retract into the mounting groove or protrude from the opening of the mounting groove. The portion of the locking block protruding from the opening of the mounting groove is the end of the elastic limiting member.

[0012] In some embodiments, the elastic limiting member further includes: a guide post, which is fixedly disposed in the mounting groove of the movable seat, and the top end of the guide post does not extend beyond the groove opening surface of the mounting groove; wherein, the elastic member is sleeved on the guide post, and the locking block has a through hole and is sleeved on the guide post through the through hole.

[0013] In some embodiments, the outer surface of the card block matches the outer wall of the stator.

[0014] In some embodiments, the first groove includes a circumferential slide groove and a clearance groove. The circumferential slide groove surrounds the second groove and the limiting part is movably disposed within the circumferential slide groove; the clearance groove is located above the circumferential slide groove, and a portion of the clearance groove is higher than the top of the stator, and a fixing structure for fixing the limiting part is provided within the clearance groove.

[0015] In some embodiments, the fixing structure includes: a fixing part disposed in the relief groove, the fixing part being fixedly connected to the limiting part so that the fixing part and the fixing part can move synchronously.

[0016] In some embodiments, the fixing part includes a connecting plate and a locking member. The connecting plate has an end connected to the limiting part and has a fixing hole higher than the top of the stator; the locking member is inserted into the fixing hole of the connecting plate and can be fixedly connected in the relief groove.

[0017] In some embodiments, when the circumferential groove is a non-closed annular groove and the outer side wall of the stator is provided with a plurality of second grooves arranged in its vertical direction, the central angle of the circumferential groove is greater than the central angle of the adjacent second groove.

[0018] In some embodiments, the refrigeration device includes a refrigeration device body and a compressor as described in the foregoing embodiments, wherein the compressor is disposed within the refrigeration device body.

[0019] The compressor and refrigeration equipment provided in this disclosure can achieve the following technical effects:

[0020] The stator is rotatably mounted within the housing via a rotating assembly, facilitating adjustment of its angle within the housing to change the root angle of the stator leads. Simultaneously, the outer wall of the stator does not directly contact the inner wall of the housing, reducing the contact area between the stator and the housing. This minimizes heat-induced deformation of the stator, thereby improving motor efficiency and noise. Furthermore, the rotating assembly also serves a positioning function, ensuring the coaxiality of the stator and rotor. Based on this, the inner wall of the housing has a first groove along its circumferential direction, and a limiting part is provided within the first groove. The outer wall of the stator has one or more second grooves arranged vertically along its circumferential direction, with the first grooves surrounding the second grooves. When the stator rotates to a set position, the limiting part moves to the intersection of the first and second grooves, inserting its end into the second groove to fix the limiting part and thus secure the stator. This allows the stator inside the compressor to be adjusted to a set angle and then fixed, improving the versatility of the stator assembly tooling, reducing the time spent switching stator assembly tooling, saving the cost of stator assembly tooling, and thus improving production efficiency.

[0038] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein.

[0040] In this disclosure, the terms "upper," "lower," "inner," "middle," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for better description of the embodiments of this disclosure and their implementations, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to require them to be constructed and operated in a specific orientation. Furthermore, some of the aforementioned terms may be used to indicate other meanings besides orientation or positional relationship; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in the embodiments of this disclosure according to the specific circumstances.

[0041] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0042] Unless otherwise stated, the term "multiple" means two or more.

[0043] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] refer to Figure 1 As shown, the rotary compressor includes a compressor housing 1a and a compressor cover 1e disposed on the upper part of the compressor housing 1a. A distributor 1h is also connected to the compressor housing 1a. Inside the compressor housing 1a, there is a fixedly connected motor stator 1b and a motor rotor 1c inserted into the motor stator 1b and rotatable relative to the motor stator 1b. A terminal 1I is provided on the motor stator 1b, and a cover terminal 1f and a cover exhaust pipe 1g are provided on the compressor cover 1e. One end of the motor stator lead 1d (i.e., the motor wire) is connected to the terminal 1I, and the other end of the motor stator lead 1d is electrically connected to the power supply line of other equipment through the cover terminal 1f.

[0047] Because heat fitting is used for assembly, the dimensional and positional tolerances of the components are less critical, which reduces the processing cost to some extent. Therefore, heat fitting is often used to fix the motor stator 1b in the compressor housing 1a. Furthermore, this method effectively ensures the coaxiality of the compressor housing 1a and the motor stator 1b, thereby ensuring the coaxiality of the motor stator 1b and the motor rotor 1c. Specifically, the compressor housing 1a is first heated, and its inner diameter increases as it expands. The heated compressor housing 1a is then fitted around the motor stator 1b. After the compressor housing 1a cools and contracts, its inner diameter decreases, allowing the inner wall of the compressor housing 1a to be assembled with the outer wall of the motor stator 1b using an interference fit. However, in this assembly method, because the contact area between the outer wall of the motor stator 1b and the inner wall of the compressor housing 1a is large, uneven cooling rates at different locations on the compressor housing 1a can lead to varying deformations in the motor stator 1b, affecting motor efficiency and noise.

[0048] On the other hand, because the wiring angles of the power cord and the top cover terminal 1f differ between different devices, various top cover assembly angles will occur when the same model of compressor is used in different devices. This top cover assembly angle is the angle between the axial line of the top cover terminal 1f, the axis of the distributor 1h, and the axis of the compressor housing 1a, forming a plane. If the angle of the motor stator 1b cannot be adjusted, the angle deviation between the motor terminal 1I and the top cover terminal 1f may be large, requiring a longer motor stator lead 1d. However, an excessively long motor stator lead 1d may affect the normal operation of the compressor. For example, the motor stator lead 1d may contact the inner wall of the compressor housing 1a, causing noise; contact the upper end of the motor rotor 1c, affecting motor efficiency; or block the inlet of the top cover exhaust pipe 1g, affecting the refrigerant nozzle's ability to add refrigerant oil to the compressor. Therefore, the angle between terminal 1I and the top cover terminal 1f is within a fixed range.

[0049] In order to enable the terminal 1I of the motor stator 1b to change with the assembly angle of the compressor cover 1e, a corresponding stator assembly fixture is configured for each stator heat fitting angle during compressor production assembly. That is, multiple sets of stator assembly fixtures are configured. This means that when producing and assembling compressors of the same specification and model, it is necessary to frequently switch the corresponding stator assembly fixtures, which not only increases the corresponding assembly cost and time cost, but also affects production efficiency.

[0050] Combination Figure 2 As shown, this embodiment of the present disclosure provides a compressor, including a housing 10, a stator 20, and a limiting device 40. The housing 10 has a first groove 11 arranged along its circumferential direction on its inner sidewall. The stator 20 is rotatably disposed within the housing 10 via a rotating assembly 30. One or more second grooves 21 are arranged along their vertical direction on the outer sidewall of the stator 20, and the first grooves 11 surround the second grooves 21. The limiting device 40 includes a limiting part 41 movably disposed within the first groove 11. When the stator 20 rotates to a set position, the limiting part 41 of the limiting device 40 is moved to the intersection of the first groove 11 and the second groove 21, so that the end of the limiting part 41 is inserted into the second groove 21, and the limiting part 41 is fixed to fix the stator 20.

[0051] In the compressor provided in this embodiment, the stator 20 is rotatably mounted within the housing 10 via the rotating assembly 30, facilitating adjustment of the angle at which the stator 20 is positioned within the housing 10 to change the root angle (i.e., the terminal) of the stator leads. Simultaneously, the outer wall of the stator 20 does not directly contact the inner wall of the housing 10, reducing the contact area between the stator 20 and the housing 10. This reduces deformation of the stator 20 due to heat, thereby improving motor efficiency and noise. Furthermore, the rotating assembly 30 also serves a positioning function, ensuring the coaxiality of the stator and rotor. Based on this, a first groove 11 is provided on the inner sidewall of the housing 10 along its circumferential direction, and a limiting part 41 is provided in the first groove 11. One or more second grooves 21 are provided on the outer sidewall of the stator 20 along its vertical direction, and the first groove 11 surrounds the second groove 21. When the stator 20 rotates to a set position, the limiting part 41 moves to the intersection of the first groove 11 and the second groove 21, so that the end of the limiting part 41 is inserted into the second groove 21, and the limiting part 41 is fixed to fix the stator 20. In this way, the stator in the compressor can be fixed after being adjusted to a set angle, improving the versatility of the stator assembly tooling, reducing the time for changing stator assembly tooling, saving the cost of stator assembly tooling, and thus improving production efficiency.

[0052] In this embodiment, in order to enable the stator 20 to rotate and adjust within the housing 10, a rotating assembly 30 is provided between the outer wall of the stator 20 and the inner wall of the housing 10. This assembly is combined with... Figure 5 At point D and Figure 6 As shown, the rotating assembly 30 can be disposed on the outer side wall of the stator 20 or the inner side wall of the housing 10.

[0053] Taking the rotating component 30 embedded in the outer wall of the stator 20 as an example, one or more annular grooves 22 are formed on the outer wall of the stator 20. The rotating component 30 is disposed in the annular groove 22, and a portion of the rotating component 30 protrudes from the annular groove 22 to abut against the inner wall of the housing 10. Optionally, the rotating component 30 can be rolled or slidably connected to the annular groove 22, and the rotating component 30 is fixedly connected to the inner wall of the housing 10. Optionally, the rotating component 30 can be rolled or slidably connected to the inner wall of the housing 10, and the rotating component 30 is fixedly connected to the annular groove 22. Optionally, the rotating component 30 itself has a rolling or sliding structure and is fixedly connected to the inner wall of the housing 10 and the annular groove 22, respectively. Optionally, the rotating component 30 includes at least one of ball bearings, needle rollers, and bearings.

[0054] Optionally, in some embodiments, when the rotating assembly 30 uses ball bearings and / or needle rollers, a plurality of ball bearings and / or needle rollers are arranged in the annular groove 22. The length of the ball bearings and / or needle rollers after they are in contact is greater than half the circumference of the annular groove 22, thus ensuring that both the left and right sides of the stator 20 have ball bearings and / or needle rollers that are interference-fitted with the inner wall of the housing 10.

[0055] Optionally, in some embodiments, when the stator 20 is relatively high, to avoid contact between the stator 20 and the housing 10, multiple annular grooves 22 can be provided in the vertical direction. Here, taking the annular groove 22 with several balls arranged in a ring as an example, and the balls being evenly distributed in a circular cross-section manner, the vertical ball spacing needs to meet the following conditions:

[0056] ΔS≤h / n;

[0057] Where ΔS is the vertical ball spacing, h is the stator height 20, and n is the number of balls on each cross-sectional circle, which is at least 3.

[0058] In this embodiment of the disclosure, when the rotating assembly 30 uses a bearing, it can be a single bearing structure or two semi-circular bearing structures. Using two semi-circular bearing structures facilitates the installation of the bearing in the annular groove 22. Optionally, the inner ring portion of the bearing is located in the annular groove 22, and the outer ring portion of the bearing is interference-fitted with the inner wall of the housing 10.

[0059] In the above embodiment, an inner wall groove that cooperates with the rotating component 30 can also be provided on the inner side wall of the housing 10. The inner wall groove cooperates with the rotating component 30 and the annular groove 22. Without the action of external force, the stator 20 will not move axially, thereby playing a positioning role and ensuring the coaxiality of the stator and the rotor.

[0060] In this embodiment of the disclosure, combined with Figure 5 As shown at point E, the inner wall of the housing 10 is interference-fitted with the outer wall of the stator 20, and the inner diameter of the housing 10 is slightly larger than the outer diameter of the stator 20. To further ensure the axial stability of the stator 20, the housing 10 is provided with an overlapping portion 12 at the bottom of the stator 20, and the bottom of the stator 20 abuts against the overlapping portion 12. The overlapping portion 12 provides axial limiting and support for the stator 20 to improve the axial stability of the stator 20.

[0061] In this embodiment of the disclosure, combined with Figure 5As shown, the overlapping portion 12 can be achieved by enlarging the upper part of the housing 10 corresponding to the stator 20, so that the upper and lower parts of the housing 10 form two housing segments with different inner diameters. A stepped structure is formed between the two housing segments, which can axially limit and support the stator 20. This stepped structure is the overlapping portion 12. Here, by enlarging the hole, the inner diameter of the upper part of the housing 10 is increased, while the inner diameter of the lower part of the housing 10 remains unchanged. In this way, under the action of the overlapping portion 12, the axial positioning depth of the stator 20 can also be determined.

[0062] After the upper housing section is enlarged, a gap δ is formed between the outer wall of the stator 20 and the inner wall of the housing section. The value of the gap δ ranges from 0 to 1.2 mm. Here, the value of the gap δ can be 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, or 1 mm, and is not limited to any particular value, as long as it ensures that the outer wall of the stator 20 does not contact the inner wall of the housing 10.

[0063] In the above embodiments, combined with Figure 5 As shown at point F, the outer edge of the top cover 50 is also provided with a stop 51 that overlaps with the opening of the housing 10. In this way, after the housing 10 is enlarged, the stop 51 of the top cover 50 can overlap the upper end of the housing 10 without affecting the subsequent welding of the top cover 50 and the housing 10.

[0064] In this embodiment, the rotating assembly 30 creates a gap between the outer wall of the stator 20 and the inner wall of the housing 10. This reduces the contact area between the stator 20 and the housing 10, decreases the deformation of the stator 20 due to heat, and reduces compressor noise during operation. The inner wall of the housing 10 and the outer wall of the rotating assembly 30 are press-fitted together via a thermal fitting, allowing the stator 20 to rotate relative to the housing 10 under external force. To limit the rotation of the stator 20, a limiting device 40 is provided on the inner wall of the housing 10. Adjusting the angle of the stator 20 allows the limiting device 40 to restrict its rotation within the housing 10.

[0065] Optionally, when the stator 20 rotates to a preset position, the terminal on the side of the stator 20 is connected to the connecting post on the upper cover 50 through the stator lead wire, and then the stator 20 is fixed by the limiting device 40 to prevent the stator 20 from rotating inside the housing 10 during the operation of the compressor.

[0066] In this embodiment, the limiting device 40 can limit and fix the stator 20 to any position it rotates to. Therefore, a first groove 11 is provided on the inner sidewall of the housing 10 along its circumferential direction; one or more second grooves 21 are provided on the outer sidewall of the stator 20 along its vertical direction, and the first groove 11 surrounds the second groove 21. The limiting device 40 includes a limiting part 41 movably disposed in the first groove 11. Thus, when the stator 20 rotates to a set position, the limiting part 41 of the limiting device 40 is moved to the intersection of the first groove 11 and the second groove 21, so that the end of the limiting part 41 is inserted into the second groove 21, and the limiting part 41 is fixed to fix the stator 20. Therefore, the limiting device 40 can limit and fix the stator 20 no matter where it rotates to.

[0067] In some alternative embodiments, the stator 20 can be fixed to the inner wall of the housing 10 by welding. Here, the limiting part 41 of the limiting device 40 is solder. After the angle of the stator 20 is adjusted, the limiting part 41 is welded to the inner wall of the housing 10 by spot welding.

[0068] In some alternative embodiments, the second groove 21 can be an oil return groove on the outer wall of the stator, so that the structure of the stator does not need to be modified and the existing structure of the stator 20 can be fully utilized.

[0069] Combination Figure 2 and Figure 3 As shown, in some embodiments, the limiting part 41 includes a movable seat 411 and an elastic limiting member 412. The movable seat 411 is movably disposed within the first groove 11; the elastic limiting member 412 is disposed on the movable seat 411. When the stator 20 rotates to a set position, the movable seat 411 is moved to the intersection of the first groove 11 and the second groove 21, and the end of the elastic limiting member 412 is inserted into the second groove 21.

[0070] In this embodiment of the disclosure, in order to facilitate the movement of the limiting part 41, combined with Figure 2 At point A and in combination Figure 3 As shown at point B, a movable seat 411 is provided within the first groove 11. The movable seat 411 can slide or roll within the first groove 11, which is not limited here. To facilitate the limitation of the stator 20, an elastic limiting member 412 is provided on the movable seat 411. During the adjustment of the stator 20 angle, the limiting member 41 can be moved by rotating the stator 20 or by actively moving the limiting member 41. Here, the limiting member 41 is engaged with the first groove 11. When the outer wall of the stator 20 has multiple vertically penetrating oil return grooves for oil return, the elastic limiting member 412 engages with at least one of the oil return grooves.

[0071] In the scenario where the rotating stator 20 drives the limiting part 41 to move, the elastic limiting member 412 is in contact with the outer wall of the stator 20 when it is not in contact with the first groove 11. The elastic limiting member 412 is always in a compressed state, and the moving seat 411 does not move. When the second groove 21 of the stator 20 passes the limiting part 41, the elastic limiting member 412 will extend into the second groove 21. At this time, the moving seat 411 can be moved within the first groove 11, and after being adjusted to a suitable position, the limiting part 41 is fixed.

[0072] In the scenario of the active movement limiting part 41, when the stator 20 rotates to the set position, the moving seat 411 is moved to the intersection of the first groove 11 and the second groove 21, and the end of the elastic limiting member 412 is inserted into the second groove 21 to fix the limiting part 41.

[0073] To ensure that the elastic limiting member 412 can accurately enter the second groove 21 and to guarantee the stability of the elastic limiting member 412, combined with Figure 2 and Figure 3 As shown, in some embodiments, the movable base 411 is provided with a mounting groove 4111, and an elastic limiting member 412 is disposed within the mounting groove 4111. The elastic limiting member 412 includes an elastic member 4121 and a locking block 4122. The first end of the elastic member 4121 is fixedly connected to the bottom of the mounting groove 4111; the locking block 4122 is fixedly connected to the second end of the elastic member 4121. Through the elastic force of the elastic member 4121, the locking block 4122 can be retracted into the mounting groove 4111 or protruded from the opening of the mounting groove 4111; wherein, the portion of the locking block 4122 protruding from the opening of the mounting groove 4111 is the end of the elastic limiting member 412.

[0074] In this embodiment, the elastic limiting member 412 includes an elastic member 4121 and a locking block 4122. A mounting groove 4111 is provided on the movable base 411, and both the elastic member 4121 and the locking block 4122 are disposed within the mounting groove 4111. Limiting is achieved through the opening of the mounting groove 4111 and the locking block 4122. Here, the elastic member 4121 can be a spring. When the elastic member 4121 is in a compressed state, it provides an outward pushing force to the locking block 4122. When the elastic member 4121 is not in a compressed state, it also prevents the locking block 4122 from disengaging from the mounting groove 4111.

[0075] When the elastic limiting member 412 is inserted into the second groove 21, part of the locking block 4122 enters the second groove 21, and another part of the locking block 4122 abuts against the groove opening side of the mounting groove 4111. This is equivalent to the two ends of the locking block 4122 being inserted into the mounting groove 4111 and the second groove 21 respectively, thus achieving the limiting function.

[0076] Optionally, in order for the locking block 4122 to slide smoothly on the outer wall of the stator 20, in some embodiments, the outer surface of the locking block 4122 matches the outer wall of the stator 20. Furthermore, the end face of the locking block 4122 that contacts the second groove 21 is also designed with rounded corners. This reduces the friction between the end face of the locking block 4122 and the outer wall of the stator 20 when the locking block 4122 is not yet in the second groove 21; and when the locking block 4122 enters the second groove 21, the rounded corners of the locking block 4122 facilitate entry into the second groove 21, preventing the locking block 4122 from experiencing difficulty in entering or locking into the second groove 21.

[0077] To further ensure that the elastic limiting member 412 can accurately enter the second groove 21 and to ensure the stability of the elastic limiting member 412, combined with Figure 2 and Figure 3 As shown, in some embodiments, the elastic limiting member 412 further includes: a guide post 4123, which is fixedly disposed in the mounting groove 4111 of the movable seat 411, and the top end of the guide post 4123 does not exceed the groove opening surface of the mounting groove 4111; wherein, the elastic member 4121 is sleeved on the guide post 4123, and the locking block 4122 has a through hole and is sleeved on the guide post 4123 through the through hole.

[0078] In this embodiment, a guide post 4123 is provided within the mounting groove 4111 to define the elastic element 4121 and the locking block 4122. The elastic element 4121 is a spring, sleeved on the guide post 4123. The guide post 4123 guides the spring, preventing the elastic element 4121 from twisting and failing. The locking block 4122 has a through hole that inserts into the guide post 4123, preventing excessive play (i.e., gap) between the locking block 4122 and the mounting groove 4111, thus preventing loosening of the locking block 4122 and the mounting groove 4111. Here, the top of the guide post 4123 does not exceed the groove surface of the mounting groove 4111. That is, when the groove surface of the mounting groove 4111 is an arc surface, the top of the guide post 4123 does not exceed the lowest position of the arc surface. Furthermore, the locking block 4122 has a certain thickness. When the locking block 4122 can enter the second groove 21, the through hole of the locking block 4122 is also connected to the guide post 4123.

[0079] Combination Figures 2 to 4 As shown, in some embodiments, the first groove 11 includes a circumferential slide groove 111 and a relief groove 112. The circumferential slide groove 111 surrounds the second groove 21, and the limiting part 41 is movably disposed within the circumferential slide groove 111; the relief groove 112 is located above the circumferential slide groove 111, and a portion of the relief groove 112 is higher than the top of the stator 20, and a fixing structure for fixing the limiting part 41 is provided within the relief groove 112.

[0080] In this embodiment, to facilitate the movement of the limiting part 41, the first groove 11 includes a circumferential sliding groove 111 and a clearance groove 112. Here, the limiting part 41 includes a movable seat 411 and an elastic limiting member 412. The second groove 21 (oil return groove) has a circumferential sliding groove 111 on its side, and the limiting part 41 is disposed within the circumferential sliding groove 111. The inner wall of the housing 10 has a clearance groove 112 located above the circumferential sliding groove 111, and a portion of the clearance groove 112 is higher than the top of the stator 20. A structure connected to the limiting part 41 is provided in this area, enabling the movement and fixation of the limiting part 41.

[0081] Here, the length of the clearance groove 112 is at least longer than that of the circumferential slide groove 111, and a fixing structure for fixing the limiting part 41 is provided in the clearance groove 112. The fixing structure includes a fixing part 42, which is disposed in the clearance groove 112 and is fixedly connected to the limiting part 41. The centers of the circumferential slide groove 111 and the clearance groove 112 are concentric with the center of the housing 10, so that the fixing part 42 and the limiting part 41 can move synchronously. Here, the longitudinal section of the circumferential slide groove 111 is a dovetail groove, and the external shape of the moving seat 411 matches the dovetail groove, thereby preventing the moving seat 411 from falling out of the circumferential slide groove 111. In this way, when the locking block 4122 of the elastic limiting member 412 retracts into the mounting groove 4111 in the moving seat 411, the end of the locking block 4122 can slide smoothly on the outer wall of the stator 20.

[0082] Combination Figures 2 to 4 As shown, in some embodiments, the fixing part 42 includes a connecting plate 421 and a locking member 423. The connecting plate 421 has its end fixedly connected to the limiting part 41, and the connecting plate 421 has a fixing hole 422 higher than the top of the stator 20; the locking member 423 is inserted into the fixing hole 422 of the connecting plate 421 and can be fixedly connected in the relief groove 112.

[0083] In this embodiment, the side of the circumferential groove 111 facing the relief groove 112 is lower, and the circumferential groove 111 communicates with the relief groove 112 through this side. The connecting plate 421 is connected to the movable seat 411 of the limiting part 41 through this side. The longitudinal height of the connecting plate 421 is higher than the top of the stator 20, so that the movable seat 411 of the limiting part 41 can move by the movement of the connecting plate 421 within the relief groove 112.

[0084] In order to facilitate subsequent adjustments to the angle of stator 20, combined with Figure 4As shown at point C, the connecting plate 421 has a fixing hole 422 in the area above the top of the stator 20. The locking member 423 is inserted into the fixing hole 422 of the connecting plate 421. The locking member 423 includes a screw, which passes through the fixing hole 422 and is fixedly connected to the relief groove 112. The locking member 423 can be removed to adjust the angle of the stator 20 later.

[0085] In some embodiments, when the circumferential groove 111 is a non-closed annular groove and the outer side wall of the stator 20 is provided with a plurality of second grooves 21 arranged in its vertical direction, the central angle of the circumferential groove 111 is greater than the central angle of the adjacent second groove 21.

[0086] In this embodiment, since the limiting part 41 moves within the circumferential groove 111, the movement path of the limiting part 41 is changed accordingly by altering the length of the circumferential groove 111. However, to ensure that the limiting part 41 can enter the second groove 21, the central angle of the circumferential groove 111 is greater than the central angles of the two adjacent second grooves 21. This is equivalent to the circumferential groove 111 surrounding the outside of at least two second grooves 21, thus ensuring that the locking block 4122 can engage with one of the second grooves 21 regardless of the angle to which the stator 20 rotates.

[0087] In conjunction with the above embodiments, during the actual assembly process, before the stator 20 is installed into the housing 10, the locking member 423 is not connected to the fixing hole 422 of the connecting plate 421, ensuring that the housing 10 can be heat-fitted onto the stator 20. After the stator 20 is installed into the housing 10, the stator 20 is rotated relative to the housing 10. Under the action of the elastic member 4121, the locking block 4122 can slide on the outer side wall of the stator 20. When adjusted to the set position, the connecting plate 421 slides circumferentially in the clearance groove 112 of the housing 10 so that the moving seat 411 slides in the circumferential sliding groove 111. The locking block 4122 moves circumferentially with the moving seat 411 and is locked into the adjacent second groove 21. Then, the locking member 423 is inserted into the fixing hole 422 to fix the connecting plate 421, thereby fixing the circumferential position of the moving seat 411 and the locking block 4122, thus fixing the circumferential position of the stator 20 and the housing 10.

[0088] In conjunction with the above embodiments, when it is necessary to readjust the angle of the stator leads later, such as when recycling a stock compressor of the same specification and model, the assembly angle of the upper cover terminal of the compressor cannot be adapted to the equipment being used. The upper cover of the stock compressor is removed from the housing 10 and the assembly angle of the upper cover terminal is adjusted. The rotation angle of the stator is adjusted in the above manner so that the terminal on the stator side and the terminal on the upper cover are within the set angle range.
