Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to compressors and air conditioners. Background Technology

[0002] Existing rotary compressors mainly consist of a distributor, upper cover, lower cover, and compressor assembly. The compressor assembly includes a housing assembly, motor, and pump body assembly. The pump body assembly includes a crankshaft, rollers, vanes, upper flange, lower flange, cylinder, and silencer.

[0003] The compressor mounting feet are evenly distributed on the housing assembly, and the distributor is installed on one side of the compressor assembly. Due to the weight of the distributor itself and the weight of the refrigerant it carries, the center of gravity of the entire compressor deviates from the center of the pump body. During compressor operation, because the center of gravity is not in the center of the pump body, the rotor causes the entire pump body to rotate eccentrically, affecting the reliability of the pump body components.

[0004] In addition, since the compressor mounting feet are evenly distributed on the housing assembly, and the center of gravity of the compressor is off-center from the pump body, when the compressor is installed on the housing system, the three mounting feet tilt due to uneven force. This causes the piping to bear certain stress when the compressor is running in the air conditioning system, which leads to a decrease in the reliability of the compressor as a whole.

[0005] Therefore, how to solve the problem of compressor center of gravity shift caused by side-mounted distributor in order to improve the reliability of the whole machine is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] The main purpose of this utility model is to provide a compressor and an air conditioner to solve the above-mentioned technical problems.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A compressor includes a housing assembly and a distributor disposed on one side outside the housing assembly, and further includes a counterweight device disposed on the other side of the housing assembly opposite to the distributor.

[0009] The counterweight device includes:

[0010] Support member, the support member being disposed on the housing assembly; and

[0011] Multiple counterweights are detachably fixed to the support member.

[0012] The supporting component includes a base and a supporting column disposed on the base; the base is fixedly disposed on the outer wall of the housing assembly, and a plurality of counterweights are sleeved on the supporting column.

[0013] The counterweight device further includes multiple elastic pads, and the multiple counterweights and multiple elastic pads are stacked alternately on the support column.

[0014] The counterweight and the elastic pad are both provided with through holes in their middle parts, and the support column passes through the through holes of the counterweight and the elastic pad.

[0015] The counterweight device further includes fasteners disposed on the support column. The fasteners and the base together form a clamping space. Multiple counterweights and multiple elastic pads are stacked in the clamping space along the axial direction of the support column.

[0016] The outer circumferential surface of the support column is provided with threads, and the fastener is a nut that mates with the threads; one of the plurality of elastic washers is disposed between the base and the adjacent counterweight, and another of the plurality of elastic washers is disposed between the fastener and the adjacent counterweight.

[0017] The base has at least two support columns spaced apart, and each support column is fitted with a plurality of counterweights.

[0018] The housing assembly includes a housing and an upper cover and a lower cover disposed on the housing. The liquid dispenser and the counterweight device are fixedly connected to opposite sides of the outer wall of the housing.

[0019] The housing contains a motor assembly and a pump assembly.

[0020] An air conditioner includes a housing and a compressor disposed within the housing, the compressor being a compressor as described above.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] This invention, by adding a counterweight device to the outside of the compressor housing assembly on the opposite side of the distributor, generates a torque that balances the weight of the distributor, thereby effectively correcting the overall center of gravity shift caused by the side-mounted distributor. Therefore, this solution avoids eccentric operation of the compressor due to an unbalanced center of gravity, reduces vibration and noise during operation, and improves operational stability and the reliability of internal pump components.

[0023] Meanwhile, the corrected center of gravity ensures even force distribution on the compressor's feet during installation, preventing the compressor from tilting and reducing additional stress on connected refrigeration pipes. This improves the compressor's installation reliability and long-term stability within the entire cooling system. Furthermore, the design of multiple detachable counterweights in the counterweight device allows for flexible adjustment of the counterweight weight according to the needs of different compressor models, enhancing the versatility and applicability of the solution.

[0042] like Figures 1-4 As shown, Figure 1 This is a schematic cross-sectional view of the compressor 100 provided in an embodiment of the present utility model; Figure 2 A top view of the compressor 100 provided in an embodiment of this utility model; Figure 3 A three-dimensional schematic diagram of the compressor 100 provided in this embodiment of the present utility model; Figure 4 for Figure 3Enlarged schematic diagram of B in the diagram. This utility model provides a compressor designed to solve the technical problem of the compressor 100's center of gravity shifting due to the side-mounted distributor 1, thus affecting the compressor 100's operational reliability. The compressor 100 includes a housing assembly 3 and a distributor 1 disposed on one side outside the housing assembly 3. It also includes a counterweight device 17 disposed on the opposite side of the housing assembly 3, opposite to the distributor 1. The counterweight device 17 includes: a support member 21 disposed on the housing assembly 3; and a plurality of counterweight blocks 20 detachably fixed to the support member 21.

[0043] In this embodiment, the compressor 100 can be a rotary compressor 100. The compressor 100 mainly includes a housing assembly 3 and a distributor 1 disposed on one side of the exterior of the housing assembly 3. As described in the background art, the distributor 1 and the refrigerant filled inside it have a certain weight. Its placement on one side of the housing assembly 3 will cause the center of gravity of the entire compressor 100 to deviate from its geometric center or pump body center. This will cause eccentric operation when the compressor 100 is running, affecting its operational stability and reliability.

[0044] To address the aforementioned issues, the compressor 100 of this embodiment further includes a counterweight device 17. This counterweight device 17 is disposed on the exterior of the housing assembly 3, and its position is opposite to that of the distributor 1. Specifically, with the central axis of the compressor 100 housing assembly 3 as a reference, the installation position of the counterweight device 17 and the installation position of the distributor 1 are approximately centrally symmetrical, for example, the angle between the two and the central axis of the housing assembly 3 is approximately 180°. Through this arrangement, the weight generated by the counterweight device 17 can effectively balance the weight on one side of the distributor 1, thereby bringing the center of gravity of the compressor 100 back to or near its geometric center, improving the problem of center of gravity shift.

[0045] Furthermore, the counterweight device 17 includes a support component 21 and a plurality of counterweight blocks 20.

[0046] The support component 21 is a basic component used to support and fix the counterweight 20, and it is directly mounted on the housing assembly 3. In this embodiment, the support component 21 can be securely installed on the outer wall of the housing assembly 3, and the connection method can adopt conventional fixing methods in the art, such as welding or screw connection, to ensure that the connection is firm and reliable.

[0047] Multiple counterweights 20 are the main components for achieving weight balance. These counterweights 20 are detachably fixed to the support component 21. "Detachably fixed" means that the counterweights 20 can be easily added, removed, or replaced according to actual needs. For example, the weight and size of the distributor 1 may differ for different models of compressors 100. In this case, the imbalance caused by the distributor 1 can be balanced by adjusting the number of counterweights 20 or the weight of a single counterweight 20 (e.g., replacing it with counterweights of different materials or sizes), making the counterweight device 17 highly flexible and applicable. Through this adjustable design, customized center of gravity balance schemes can be provided for compressors 100 of different specifications, thereby improving the reliability and stability of compressor 100 operation and reducing operating noise caused by vibration.

[0048] In this embodiment, in order to achieve torque balance in the horizontal direction of the compressor 100, the weights and installation positions of the distributor 1 and the counterweight device 17 need to satisfy a specific relationship. Specifically, the total weight of the counterweight device 17 should satisfy the following condition: m1r1 - m2r2 = 0, that is, m1r1 = m2r2.

[0049] Wherein: m1 is the total weight of the distributor 1 (including the refrigerant filled inside it);

[0050] r1 is the distance from the centroid of the dispenser 1 to the center line of the housing assembly 3;

[0051] m2 is the total weight of the counterweight device 17, which can be adjusted by increasing or decreasing the number of counterweights 20 or by changing the material / size of a single counterweight 20.

[0052] r2 is the distance from the center of mass of the counterweight device 17 to the center line of the housing assembly 3.

[0053] This condition ensures that the offset torque (m1r1) generated by the distributor 1 is equal in magnitude and opposite in direction to the balancing torque (m2r2) generated by the counterweight device 17, thereby enabling the overall center of mass of the compressor 100 to be returned to or near the center line of the housing assembly 3. This quantitative design effectively eliminates the center of mass shift problem caused by the side-mounted distributor 1, improving the smoothness of compressor 100 operation and reducing vibration and noise.

[0054] In this embodiment, the counterweight device 17 is positioned outside the housing assembly 3, thus avoiding the occupation of the limited internal space of the housing assembly 3. The interior of the housing assembly 3 needs to provide sufficient space for the motor assembly 6, pump assembly 8, and circulating refrigerant oil 4. In this embodiment, the counterweight device 17 is positioned externally, completely avoiding interference with the arrangement of internal components and requiring no changes to the internal volume or structure of the housing assembly 3, thereby ensuring the design freedom and performance stability of the compressor's core components.

[0055] Meanwhile, this external configuration simplifies the compressor assembly process. The installation, adjustment, or replacement of the counterweight device 17 can be performed after the housing assembly 3 has been sealed and welded and all internal components have been assembled. This decouples the weight balance calibration process from the compressor body manufacturing process, reducing assembly complexity. Furthermore, since the counterweight 20 is detachable, the number of counterweights 20 can be flexibly increased or decreased, or different specifications of counterweights can be replaced, according to the actual needs of different compressor models. Adjustments can even be made after the product leaves the factory based on changes in application scenarios, improving overall maintainability.

[0056] In one embodiment, the support component 21 includes a base 212 and a support column 211 disposed on the base 212; the base 212 is fixedly disposed on the outer wall of the housing assembly 3, and a plurality of counterweights 20 are sleeved on the support column 211.

[0057] Please refer to the following: Figure 3 and Figure 4 In this embodiment, the support component 21 specifically includes a base 212 and a support column 211 disposed on the base 212.

[0058] The base 212 is the part that connects the supporting component 21 to the housing assembly 3. Specifically, the base 212 has a contact surface that matches the contour of the outer wall of the housing assembly 3, through which the base 212 can be fixedly mounted on the outer wall of the housing assembly 3. As mentioned above, the fixing method can be welding to form a permanent and secure connection, or a detachable connection method such as screw connection for easy replacement. The base 212 provides a stable mounting foundation for the entire counterweight device 17.

[0059] The support column 211 is fixedly mounted on the base 212 and extends upward from the base 212. The support column 211 can be a solid or hollow column, and its main function is to provide a reference for the installation and positioning of multiple counterweights 20.

[0060] In this embodiment, multiple counterweights 20 are sleeved on the support column 211. Specifically, the structure of the multiple counterweights 20 allows them to be installed and stacked around the support column 211 as an axis. During assembly, multiple counterweights 20 can be sequentially installed onto the support column 211, forming a stacked structure arranged along the axial direction of the support column 211. This sleeved installation method is not only simple in structure and convenient in assembly, but also ensures that the multiple counterweights 20 remain aligned on the support column 211, making the counterweight effect more concentrated and stable. At the same time, this also provides structural convenience for subsequently adding or removing the number of counterweights 20 for fine-tuning the weight.

[0061] In one embodiment, the counterweight device 17 further includes a plurality of elastic pads 19, and the plurality of counterweight blocks 20 and the plurality of elastic pads 19 are stacked alternately on the support column 211.

[0062] Please continue reading. Figure 4 In this embodiment, the counterweight device 17 includes not only the support component 21 and multiple counterweight blocks 20, but also multiple elastic pads 19.

[0063] The elastic pad 19 is a component with certain elasticity or cushioning properties. In specific implementations, the elastic pad 19 can be made of high molecular elastic materials such as rubber, silicone, and nylon.

[0064] In the assembly structure, the multiple counterweights 20 and multiple elastic pads 19 are arranged in an alternating stacked manner on the support column 211. Specifically, an elastic pad 19 is placed between two adjacent counterweights 20, thereby forming a stacked structure of "counterweight 20-elastic pad 19-counterweight 20". Through this spaced arrangement, each counterweight 20 is elastically isolated from other rigid components (such as other counterweights) by the elastic pads 19.

[0065] On the one hand, the elastic shim 19 can play a role in buffering and vibration reduction. During the operation of the compressor 100, vibrations are inevitable and these vibrations will be transmitted to the counterweight device 17. The presence of the elastic shim 19 can effectively absorb and attenuate these vibration energies, prevent impact or friction noise caused by rigid contact between the counterweights 20, and thus further reduce the overall operating noise of the compressor 100.

[0066] On the other hand, the elastic deformation of the elastic pad 19 can compensate for manufacturing and assembly tolerances to a certain extent, so that the entire stack of counterweight 20 components can be more tightly and securely fastened, avoiding abnormal noises and potential reliability risks caused by gaps or looseness.

[0067] In summary, by adding elastic pads 19 and adopting an alternating stacking structure, this embodiment not only ensures the realization of the counterweight function, but also solves potential vibration and noise problems by utilizing elastic elements, thereby improving the overall performance of the compressor 100 and the user experience.

[0068] In one embodiment, both the counterweight 20 and the elastic pad 19 are provided with through holes 191 in the middle, and the support column 211 passes through the through holes 191 of the counterweight 20 and the elastic pad 19.

[0069] Please see Figure 5 , Figure 5 This is a schematic diagram of the counterweight 20 and its elastic gasket 19 in the compressor 100 provided in this embodiment of the present invention. In this embodiment, each counterweight 20 has a through hole 191 in the middle. The through hole 191 can be a circular hole or other hole type that matches the cross-sectional shape of the support column 211, and its diameter is slightly larger than the outer diameter of the support column 211 to ensure that the counterweight 20 can slide and be positioned smoothly along the support column 211, while leaving a certain gap to accommodate assembly tolerances. The through hole 191 is located in the middle of the counterweight 20, which helps to maintain the balance and stability of the counterweight 20 during installation and avoids affecting the counterweight effect due to eccentricity.

[0070] Similarly, each elastic pad 19 is also provided with a through hole 191 in the middle. The shape and size design principle of the through hole 191 is similar to that of the through hole 191 of the counterweight 20.

[0071] During assembly, the support column 211 passes through the through holes 191 of the multiple counterweights 20 and multiple elastic washers 19. Specifically, first, the through hole 191 of one counterweight 20 is aligned with the support column 211 and inserted, then the through hole 191 of one elastic washer 19 is aligned with the support column 211 and inserted, and so on alternately, until all counterweights 20 and elastic washers 19 are inserted into the support column 211, forming an alternating stacked structure. This insertion method ensures that all components are aligned and fixed with the support column 211 as the axis, avoiding offset or misalignment.

[0072] By providing through holes 191 in the middle of the counterweight 20 and the elastic pad 19, and allowing the support column 211 to pass through these through holes 191, this embodiment achieves modular assembly of the counterweight device 17, facilitating quick assembly and adjustment by operators. Simultaneously, this structure enhances overall stability, ensuring reliable fixation of the counterweight 20 under the vibration environment of the compressor 100, further improving the smooth operation of the compressor 100.

[0073] In one specific embodiment, both the counterweight 20 and the elastic pad 19 are disc-shaped. The disc-shaped counterweight 20 and elastic pad 19 better adapt to the cylindrical structure of the support column 211 during assembly, ensuring uniform weight distribution and stable stacking. This shape design facilitates manufacturing and processing, while also helping to reduce edge stress concentration and improve component durability.

[0074] In one embodiment, the counterweight device 17 further includes a fastener 18 disposed on the support column 211. The fastener 18 and the base 212 together form a clamping space, and a plurality of counterweight blocks 20 and a plurality of elastic pads 19 are stacked axially along the support column 211 within the clamping space.

[0075] Please refer to the following: Figure 3 and Figure 4 In this embodiment, the counterweight device 17 further includes a fastener 18 disposed on the support column 211. The function of the fastener 18 is to apply axial pressure to the multiple counterweights 20 and multiple elastic pads 19 that are sleeved on the support column 211, so as to reliably fix them and prevent them from loosening, displacing or rotating during the operation of the compressor 100.

[0076] Specifically, the fastener 18 and the base 212 in the support member 21 together form a clamping space. This clamping space is an area defined in the axial direction of the support column 211 by a surface of the base 212 (e.g., the upper surface at the connection between the base 212 and the support column 211) and a surface of the fastener 18 (e.g., the lower surface of the fastener 18 facing the base 212).

[0077] The multiple counterweights 20 and multiple elastic pads 19 are stacked along the axial direction of the support column 211 within this clamping space. After assembly, by tightening the fasteners 18, the distance between the base 212 and the fasteners 18 can be reduced, thereby applying a preload force to all the counterweights 20 and elastic pads 19 within the clamping space.

[0078] Under the action of the preload, the elastic pad 19 will undergo a certain degree of elastic compression, thereby generating sufficient friction to firmly fix each counterweight 20 to the support column 211, preventing them from axial movement and circumferential rotation. At the same time, this clamping and fixing method also ensures that the entire counterweight assembly becomes a compact and stable whole, which can effectively resist the vibration and impact generated by the compressor 100 during operation.

[0079] By adding fasteners 18 and using the clamping space formed by them and the base 212 to fix the counterweight 20 and the elastic pad 19, this embodiment provides a simple and effective fixing solution. It not only makes it easy to adjust the number of counterweights 20 stacked according to the actual weight balance requirements, but also ensures the structural stability and long-term reliability of the counterweight device 17.

[0080] In one embodiment, the outer peripheral surface of the support column 211 is provided with threads, and the fastener 18 is a nut that engages with the threads; wherein, one of the plurality of elastic washers 19 is disposed between the base 212 and the adjacent counterweight 20, and another of the plurality of elastic washers 19 is disposed between the fastener 18 and the adjacent counterweight 20.

[0081] Please continue reading. Figure 4 In this embodiment, the outer circumferential surface of the support column 211 is provided with threads (not separately marked in the figure). Specifically, the threads can be a standard external thread structure, distributed at the end of the support column 211 away from the base 212 or along most of its length, to provide sufficient thread length for subsequent tightening. This thread design allows the support column 211 to not only provide support and positioning but also to perform a tightening function, simplifying the overall structure of the counterweight device 17.

[0082] Accordingly, the fastener 18 is a nut that mates with the thread. The nut has an internal thread whose thread specification matches the external thread of the support column 211. During assembly, the nut can be screwed into the threaded end of the support column 211, and its axial position on the support column 211 can be adjusted by rotating the nut, thereby applying a controllable axial tightening force to the components within the clamping space. This threaded engagement method is simple and reliable to operate, and allows for fine adjustment of the preload.

[0083] Furthermore, the positions of the plurality of elastic pads 19 are specifically defined. One of the elastic pads 19 is positioned between the base 212 and the adjacent counterweight 20. Specifically, this elastic pad 19 is in close contact with the upper surface of the base 212 and serves as the starting point of the stacked structure, contacting the lower surface of the first counterweight 20. This arrangement prevents the counterweight 20 from directly contacting the rigid surface of the base 212, providing initial elastic cushioning.

[0084] Additionally, another of the plurality of elastic washers 19 is disposed between the fastener 18 (i.e., the nut) and the adjacent counterweight 20. Specifically, this elastic washer 19 is located at the end of the stacked structure, in contact with the upper surface of the last counterweight 20, and is pressed against the inner surface of the nut. This elastic washer 19 prevents the nut from directly pressing against the counterweight 20, preventing localized stress concentration, and provides elastic compensation when tightening the nut, ensuring that the entire stacked assembly remains stable and does not loosen after tightening.

[0085] In actual assembly, the first elastic washer 19 is first placed on the base 212, then the counterweights 20 and additional elastic washer 19 are stacked alternately, and finally another elastic washer 19 is placed on the topmost counterweight 20 and the nut is tightened. With this arrangement, the elastic washer 19 not only provides crucial cushioning at the beginning and end, but also enhances the overall vibration damping effect, further reducing the noise of the compressor 100 during operation.

[0086] By designing the support column 211 as a threaded structure, the fastener 18 as a nut, and specifying the elastic washers 19 at specific positions at both ends of the base 212 and the fastener 18, this arrangement ensures that the entire rigid centroid stack composed of counterweights 20 is flexibly connected to the rigid components (base 212 and fastener 18) at both ends through the elastic washers 19. This is equivalent to "floating" the counterweight stack 20 between two elastic elements, which can absorb and attenuate vibration energy to the greatest extent.

[0087] In one embodiment, at least two support columns 211 are spaced apart on the base 212, and each support column 211 is fitted with a plurality of counterweights 20.

[0088] Please see Figure 6 , Figure 6 This is a schematic diagram showing the arrangement of two support columns 211 in the compressor 100 provided in this embodiment of the present invention. In this embodiment, at least two support columns 211 are spaced apart on the base 212. Specifically, these support columns 211 can be distributed in parallel on the base 212, maintaining a certain distance from each other to form a multi-point support layout. For example, two, three, or more support columns 211 can be provided, and the specific number and spacing can be adjusted according to the specifications of the compressor 100, the weight distribution of the distributor 1, and the actual needs of the installation environment.

[0089] Each of the support columns 211 is fitted with a plurality of counterweights 20. Specifically, for each support column 211, multiple counterweights 20 can be independently installed on it. These counterweights 20 are sequentially fitted and stacked along the axial direction of the support column 211 to form an independent counterweight unit. The number of counterweights 20 on different support columns 211 can be the same or different. For example, three counterweights 20 are fitted on one support column 211, while two are fitted on another.

[0090] This embodiment offers greater flexibility through the design of multiple support columns 211. Specifically:

[0091] On the one hand, when the center of gravity of the compressor 100 is not strictly along the line connecting the center of the distributor 1 and the housing assembly 3 (for example, the center of gravity is biased to one side), the balance in the three-dimensional direction can be achieved by distributing different numbers or weights of counterweights 20 on different support columns 211, thereby more effectively bringing the center of gravity of the whole machine back to the center of the pump body and improving the stability and reliability of operation.

[0092] On the other hand, when the compressor 100 is installed in a confined space such as an air conditioning system, using a single support column 211 and stacking too many counterweights 20 may cause interference with air conditioning ducts or other components in the height direction. By using multiple support columns 211, the total counterweight mass can be distributed among multiple stacked units of lower height, reducing the overall height occupation while maintaining the required counterweight effect. This design avoids the problems caused by simply increasing the size (e.g., diameter or height) of a single counterweight 20, because an excessively large counterweight 20 may increase the overall volume of the compressor 100, making it unsuitable for space-constrained installation scenarios.

[0093] In summary, by setting at least two support columns 211 at intervals on the base 212 and fitting multiple counterweights 20 on each column, this embodiment achieves a modular and scalable counterweight scheme, which is suitable for various complex center of gravity offset and spatial constraints, further improving the adaptability and practicality of the compressor 100.

[0094] In one embodiment, the housing assembly 3 includes a housing 7 and an upper cover 2 and a lower cover 5 disposed on the housing 7, wherein the liquid dispenser 1 and the counterweight device 17 are fixedly connected to opposite sides of the outer wall of the housing 7.

[0095] Please refer to the following: Figure 1 and Figure 2In this embodiment, the housing assembly 3 of the compressor 100 serves as the main structure for housing and protecting the internal working components, and is assembled from multiple parts by welding or assembly. Specifically, the housing assembly 3 includes a hollow cylindrical housing 7, an upper cover 2 fixed to the upper end of the housing 7, and a lower cover 5 fixed to the lower end of the housing 7. The upper cover 2, the lower cover 5, and the housing 7 together form a sealed internal cavity for housing components such as the motor assembly 6 and the pump assembly 8, and for storing refrigerant oil 4.

[0096] Both the liquid dispenser 1 and the counterweight device 17 are fixedly connected to the outer wall of the housing 7. As the main load-bearing part of the housing assembly 3, the housing 7 has sufficient strength and rigidity to provide a stable and reliable mounting base for the liquid dispenser 1 and the counterweight device 17.

[0097] More specifically, the distributor 1 is fixed to one side of the outer wall of the housing 7, while the counterweight 17 is fixed to the opposite side of the outer wall of the housing 7. This arrangement, where the counterweight 17 is directly fixed to opposite sides of the housing 7, allows the balancing torque generated by the counterweight 17 to most directly and effectively counteract the eccentric torque caused by the distributor 1, thereby achieving optimal center of gravity balance and ensuring the stability and reliability of the compressor 100 during operation.

[0098] In one embodiment, a motor assembly 6 and a pump assembly 8 are disposed within the housing 7.

[0099] Please see Figure 1 In this embodiment, the power source and actuator of the compressor 100 are provided within the sealed cavity formed by the housing 7, the upper cover 2, and the lower cover 5. Specifically, the housing 7 contains a motor assembly 6 and a pump assembly 8.

[0100] The motor assembly 6 includes a stator fixed to the inner wall of the housing 7 and a rotor rotatably disposed within the stator, and its function is to provide driving force for the operation of the compressor 100.

[0101] The pump assembly 8 is the mechanism for compressing the refrigerant. It is connected to the rotor of the motor assembly 6 through a transmission mechanism such as a crankshaft, converting the rotational motion output by the motor assembly 6 into compression work. The specific structure of the pump assembly 8 may include components such as cylinders, rollers, vanes, upper flanges, and lower flanges (not individually marked in the figure). These components work together to complete the process of drawing in, compressing, and discharging refrigerant gas.

[0102] During the operation of compressor 100, motor assembly 6 drives pump body assembly 8. Due to the presence of distributor 1, the center of gravity of the entire unit deviates from the center of pump body assembly 8. By setting a counterweight device 17 on the outside of housing 7 opposite to distributor 1, the center of gravity of the entire unit can be returned to near the center of pump body assembly 8, thereby effectively avoiding eccentric operation caused by the center of gravity shift, improving the stability of pump body assembly 8 and even the entire compressor 100 operation and the reliability of components.

[0103] like Figure 8 As shown, Figure 8 This is a schematic diagram of an air conditioner 200 provided in an embodiment of the present invention. Corresponding to the compressor described above, this embodiment of the present invention also provides an air conditioner designed to improve the stability of overall operation, reduce noise, and enhance long-term reliability by employing a compressor 100 with optimized center of gravity balance. The air conditioner 200 includes a housing 210 and a compressor 100 disposed within the housing 210, wherein the compressor 100 is the compressor 100 described in the preceding embodiments.

[0104] In this embodiment, the air conditioner 200 includes a housing 210 and a compressor 100 disposed within the housing 210. The housing 210 is the external frame structure of the air conditioner 200, used to house and protect its internal functional components, such as heat exchangers, fans, control circuits, and refrigeration piping systems (not shown in the accompanying drawings).

[0105] The compressor 100 used in the air conditioner 200 has a liquid distributor 1 on one side of its housing assembly 3, and a counterweight device 17 on the opposite side of the liquid distributor 1. The counterweight device 17 includes a support member 21 and a plurality of counterweight blocks 20 detachably fixed to the support member 21.

[0106] By employing a compressor 100 with a counterweight device 17, the weight of the distributor 1 and its internal refrigerant can be effectively balanced, bringing the center of gravity of the compressor 100 back to near its geometric center. When the compressor 100 is installed in the refrigeration system of the air conditioner 200 and begins operation, the optimized balance of its center of gravity reduces vibration and noise caused by eccentric operation.

[0107] This reduction in vibration and noise not only enhances the user experience of the air conditioner 200 itself, making its operation quieter and smoother, but also reduces the impact and stress of compressor 100 vibration on the connected refrigeration pipes, reducing the risk of pipe leakage due to vibration fatigue, thereby improving the long-term operational reliability and service life of the entire air conditioner 200 system.

[0108] In summary, the air conditioner 200 of this embodiment solves the problem of compressor 100 center of gravity offset from the source by integrating the compressor 100 described in any of the above embodiments, bringing better performance and higher reliability to the whole machine.

[0109] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
