Description

Technical Field

[0001] The utility model relates to the technical field of liquid accumulators, and in particular to a liquid accumulator and a compressor having the same. Background Art

[0002] Currently, the liquid accumulator is a key component in compressors. It is primarily used to store gaseous and liquid refrigerants, allowing the liquid refrigerant to be fully vaporized for easy intake by the compressor pump. It also serves as a filter, silencer, and refrigerant buffer.

[0003] However, the main noise source of the compressor is the liquid reservoir. The noise generated by the liquid reservoir mainly comes from the high-pressure air flow pulsation inside the liquid reservoir. The regular air flow pulsation can easily excite the liquid reservoir mode to produce abnormal sound. In order to improve the noise reduction performance of the liquid reservoir, the existing technology usually sets an air suction muffler on the suction pipe of the liquid reservoir to reduce the noise of the compressor suction process. However, the suction muffler on the suction pipe has poor suction muffler performance. Even if the noise reduction muffler is filled with sound-absorbing material, the final sound reduction performance still cannot achieve the expected effect. In addition, the current development and design of compressors pay more and more attention to cost control and standardized design. Due to the size and standardization of air conditioners, the external dimensions of the compressor liquid reservoir are usually standard values. The existing noise reduction measures often lead to changes in the external dimensions of the liquid reservoir, which cannot adapt to the standardized inner cavity of the liquid reservoir.

[0053] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0054] like Figures 1 to 5 As shown, the first embodiment of the present invention provides a liquid reservoir, comprising a barrel 10 and a noise reduction assembly 20. The barrel 10 defines a storage space 11 for storing fluid. The noise reduction assembly 20 is disposed within the storage space 11; the noise reduction assembly 20 extends helically along the extension direction of the barrel 10.

[0055] The liquid reservoir provided by the first embodiment of the present invention can effectively break the airflow pulsation pattern inside the liquid reservoir through the spirally extended noise reduction component 20, reduce or eliminate the modal response of the liquid reservoir excited by the regular airflow pulsation, thereby significantly reducing the high-frequency whistling sound generated by the liquid reservoir during the operation of the compressor. In addition, the spiral structure can make the fluid distribution more uniform while changing the fluid path, reduce the radial movement of the fluid, thereby reducing the impact of the fluid on the cylinder wall and reducing the noise and vibration generated by the fluid flow. On this basis, the spiral setting of the noise reduction component 20 can also optimize the fluid resistance. Through the reasonable design of the noise reduction component 20 (such as pitch, thickness, number of turns), it can be ensured that while suppressing high-frequency noise, the resistance to fluid flow is minimized, maintaining the high-efficiency operation of the liquid reservoir. Compared with the traditional method of adding additional silencers or changing the size of the liquid reservoir, this design does not require new parts and does not change the external dimensions of the liquid reservoir. Therefore, it can effectively control costs and meet the standardized design requirements of air-conditioning compressors. This configuration is not only suitable for specific compressor models, but also, while maintaining the same diameter, can be widely applied to different compressors, resolving the problem of high-frequency whistling, demonstrating excellent adaptability and versatility. Therefore, the liquid reservoir provided in this embodiment can resolve the technical problem of high internal noise in liquid reservoirs in the prior art.

[0056] Specifically, the extending direction of the cylinder 10 is the height direction of the cylinder 10 .

[0057] Specifically, an air intake port 12 and an air outlet port 13 are provided on the cylinder 10. The liquid reservoir also includes an air intake pipe 30, one end of which is inserted into the air outlet port 13, and the other end of the air intake pipe 30 is located in the storage space 11. One side of the noise reduction component 20 is connected to the outer wall of the air intake pipe 30. With such a structural arrangement, the arrangement of the air intake port 12 and the air outlet port 13 ensures that the liquid reservoir can be effectively connected to other components of the compressor, ensuring the smooth entry and exit of gaseous and liquid refrigerants. At the same time, the arrangement of the air intake port 12 and the air outlet port 13 at specific positions of the cylinder 10 helps to optimize the internal fluid path of the liquid reservoir and reduce the noise and vibration generated during the flow of the fluid. On this basis, by connecting one end of the intake pipe 30 to the air outlet 13 and extending the other end into the storage space 11 of the liquid reservoir, it can be ensured that during the compressor intake process, the fluid can stably enter the compressor pump body through the intake pipe 30, and at the same time, it is beneficial for the fluid to be fully mixed and vaporized inside the liquid reservoir, reducing the possibility of droplets entering the compressor pump body, and improving the operating efficiency and stability of the compressor.

[0058] Specifically, in order to improve the air intake efficiency, the air intake pipe 30 is a straight pipe.

[0059] Specifically, the cylinder 10 is provided with an air intake port 12 and an air outlet 13. The liquid reservoir also includes an air intake pipe 30, one end of which is inserted into the air outlet 13, and the other end of the air intake pipe 30 is located in the storage space 11. The other side of the noise reduction component 20 is connected to the inner wall of the cylinder 10. With such a structural setting, the fixed connection between the noise reduction component 20 and the inner wall of the cylinder 10 can stably support the noise reduction component, improve the support rigidity of the air intake pipe 30, and reduce the shaking noise of the air intake pipe 30.

[0060] Specifically, one side of the noise reduction component 20 is connected to the outer wall of the intake pipe 30. The other side of the noise reduction component 20 is connected to the inner wall of the cylinder 10. With this structural arrangement, the fixed connection between the noise reduction component 20 and the outer wall of the intake pipe 30 and the inner wall of the cylinder 10 not only stably supports the noise reduction component, improves the support rigidity of the intake pipe 30, and reduces the shaking noise of the intake pipe 30, but also significantly changes the flow path of the fluid inside the liquid reservoir through spiral extension, effectively suppressing the high-frequency noise caused by fluid pulsation, while reducing the vibration of the intake pipe 30, further reducing the noise level.

[0061] Specifically, the noise reduction component 20 is spirally extended around the central axis of the cylinder 10. With this structural arrangement, the spirally extended noise reduction component 20 can significantly increase the turbulence of the fluid inside the reservoir, preventing regular fluid pulsation from resonating with the reservoir structure, thereby effectively reducing high-frequency whistling sounds inside the reservoir. Furthermore, the spiral structure helps increase the residence time of the fluid inside the reservoir, promoting the vaporization of the liquid refrigerant and improving the refrigeration performance of the compressor.

[0062] Specifically, an oil return port 31 is provided on the intake pipe 30, located on the side of the noise reduction assembly 20 near the air outlet 13. This structural arrangement ensures that the refrigerant oil within the reservoir can flow back through the oil return port 31, preventing the accumulation of refrigerant oil in the reservoir and affecting the lubrication and refrigeration performance of the compressor. Furthermore, the location of the oil return port 31 helps evenly distribute the fluid before it enters the compressor pump body, reducing compressor vibration and noise.

[0063] In this embodiment, the noise reduction assembly 20 is a plate-like structure with an average thickness greater than or equal to 1 mm and less than or equal to 1.5 mm. This structural arrangement limits the thickness of the plate-like structure of the noise reduction assembly 20 to between 1 mm and 1.5 mm, helping to ensure the rigidity and stability of the noise reduction assembly 20 while reducing resistance to fluid flow. This thickness of the baffle effectively alters the fluid path while maintaining structural strength, reducing noise generation and being particularly effective in suppressing high-frequency whistling.

[0064] Specifically, if Figure 2 As shown, the pitch of the noise reduction component 20 is d, where d ≥ 20 mm. This structural arrangement ensures effective interaction between the noise reduction component 20 and the fluid. When the pitch is greater than or equal to 20 mm, the noise reduction component 20 can create a sufficiently large disturbance in the fluid to disrupt the original fluid pulsation pattern, thereby significantly reducing abnormal noise caused by fluid pulsation. Furthermore, this pitch avoids excessive obstruction to fluid circulation, ensuring fluid dynamics balance.

[0065] Specifically, if Figure 2 As shown, the width W of the noise reduction assembly 20 is constant along its extension direction. Maintaining a consistent width of the noise reduction assembly 20 along its extension direction helps maintain its uniform distribution within the reservoir, ensuring that the fluid is evenly disturbed as it passes through the noise reduction assembly 20, promoting uniform fluid distribution, thereby improving the efficiency of noise reduction and fluid separation and reducing the generation of localized noise.

[0066] It should be noted that if Figure 2 As shown, the width W of the noise reduction component 20 is the width from one side to the other side of the noise reduction component 20.

[0067] In this embodiment, the cylinder 10 includes an upper cover portion 101, a main body portion 102 and a lower cover portion 103 connected in sequence; an air intake port 12 is provided on the upper cover portion 101, and an air outlet port 13 is provided on the lower cover portion 103. Among them, along the extension direction of the cylinder 10, the length of the noise reduction component 20 is L1, the length of the main body portion 102 is L0, and 1 / 3≤L1 / L0≤4 / 5. With such a structural arrangement, the arrangement of the upper cover portion 101, the main body portion 102 and the lower cover portion 103 not only optimizes the assembly and maintenance of the liquid reservoir, but also ensures that the fluid can smoothly enter and exit the liquid reservoir through the air intake port 12 of the upper cover portion 101 and the air outlet port 13 of the lower cover portion 103, reduces the resistance and turbulence of the fluid flow, and contributes to the fluid management and noise control inside the liquid reservoir. On this basis, by limiting the length ratio of the noise reduction assembly 20 to the main body 102, it is possible to ensure that the noise reduction assembly 20 is properly distributed within the reservoir, covering sufficient fluid paths, thereby effectively reducing high-frequency noise within the reservoir. Furthermore, this ratio is designed to take into account the ease of installation of the noise reduction assembly 20 and the overall space utilization of the reservoir, avoiding fluid flow obstruction or installation difficulties caused by an excessively long noise reduction assembly 20, thereby ensuring efficient operation and easy maintenance of the reservoir.

[0068] In this embodiment, the cylinder 10 includes an upper cover portion 101, a main body portion 102 and a lower cover portion 103 connected in sequence; an air inlet 12 is provided on the upper cover portion 101, and an air outlet 13 is provided on the lower cover portion 103. Among them, along the direction from the upper cover portion 101 to the lower cover portion 103, the noise reduction component 20 extends in a spiral clockwise direction. With such a structural setting, the noise reduction component 20 that extends in a spiral clockwise direction is selected to change the flow direction of the fluid inside the reservoir in a targeted manner. The clockwise spiral path helps the fluid to contact the noise reduction component 20 more fully, increases the turbulent effect of the fluid, thereby destroying the regular airflow pulsation inside the reservoir and effectively reducing high-frequency whistling sounds. In addition, the specific spiral direction helps to improve the distribution of the fluid in the reservoir, reduce the direct impact of the fluid on the wall of the cylinder 10, further reduce the reservoir noise, and improve the operating stability of the compressor.

[0069] In this embodiment, the cylinder 10 includes an upper cover portion 101, a main body portion 102 and a lower cover portion 103 connected in sequence; an air inlet 12 is provided on the upper cover portion 101, and an air outlet 13 is provided on the lower cover portion 103. Among them, along the extension direction of the main body portion 102, the noise reduction component 20 is provided in the middle of the main body portion 102. In this way, arranging the noise reduction component 20 in the middle of the main body portion 102 can make full use of the internal space of the liquid reservoir. In this way, the noise reduction component 20 can more effectively affect the main flow area of ​​the fluid, rather than being limited to the local area near the air inlet 12 or the air outlet 13. The positioning of the middle of the main body portion 102 helps to evenly distribute the noise reduction effect throughout the inner cavity of the liquid reservoir, thereby further reducing the generation of abnormal high-frequency noise inside the liquid reservoir, while maintaining the smoothness and efficiency of the fluid flow, optimizing the refrigerant buffering and gas-liquid separation functions of the liquid reservoir, and improving the overall performance of the compressor.

[0070] Specifically, the noise reduction component 20 is a single noise reduction plate. Using a single plate as the noise reduction component 20 simplifies the internal structure of the reservoir, reducing the number of components and assembly complexity, thereby lowering manufacturing costs and improving production efficiency. The use of a single plate also ensures uniform distribution of the noise reduction effect, avoids mutual interference between multiple components, and makes the noise suppression mechanism more focused and effective. It can provide stable noise reduction for high-frequency whistling sounds of specific frequencies, thereby improving overall noise control capabilities.

[0071] Specifically, the noise reduction component 20 is a noise reduction plate. The number of rotations of the noise reduction plate is greater than or equal to 1.5 and less than or equal to 3. This structural arrangement limits the number of rotations of the noise reduction plate to between 1.5 and 3, aiming to improve fluid dynamics through the physical properties of the spiral structure. The selection of the number of rotations of the noise reduction plate can provide sufficient path length to increase the contact time between the fluid and the noise reduction plate, thereby more effectively disrupting regular airflow pulsations and reducing high-frequency noise. At the same time, it avoids the increase in fluid resistance caused by excessive rotation, maintains the smooth flow of the fluid within the reservoir, optimizes the compressor's suction process, and improves refrigeration performance.

[0072] It should be noted that the number of revolutions of the noise reduction plate refers to the number of spiral turns of the noise reduction plate along the extension direction of the cylinder 10. When the number of revolutions of the noise reduction plate is 1.5, the noise reduction plate spirally extends 540° around the rotation axis. When the number of revolutions of the noise reduction plate is 3, the noise reduction plate spirally extends 1080° around the rotation axis.

[0073] Specifically, the noise reduction assembly 20 is a plurality of noise reduction plates, and the plurality of noise reduction plates are spaced apart along the extension direction of the cylinder 10. With such a structural arrangement, a plurality of noise reduction plates spaced apart are used, and a plurality of noise reduction areas can be created inside the reservoir, and each noise reduction plate can act independently on the fluid to form a multi-level noise suppression effect. This design increases the complexity of the fluid path inside the reservoir and increases the contact frequency between the fluid and the noise reduction plate, thereby more effectively eliminating the airflow pulsation inside the reservoir and reducing high-frequency howling. The multi-plate spacing arrangement can also reduce the size and weight of a single noise reduction plate, improve the stability of the structure and the flexibility of installation, while reducing the resistance to fluid flow and maintaining high-efficiency operation of the compressor.

[0074] In this embodiment, the noise reduction component 20 is provided with a flow hole 21 for allowing the fluid to pass through. There are multiple flow holes 21, and the multiple flow holes 21 are spaced apart on the noise reduction component 20. With such a structural arrangement, the fluid passes through the noise reduction plate in a specific path, increasing the path length and turbulence of the fluid, thereby effectively suppressing the regular pulsation of the airflow inside the liquid reservoir and reducing the high-frequency noise generated thereby. In addition, such an arrangement can reduce the resistance to the intake fluid and increase its longitudinal flow area. At the same time, the interval arrangement of the flow holes 21 can ensure the uniformity of the fluid distribution, improve the gas-liquid separation effect during the intake process, reduce the risk of liquid refrigerant entering the compressor pump body, and improve the operating efficiency and reliability of the compressor.

[0075] Specifically, the noise reduction assembly 20 is provided with a flow hole 21 for fluid passage. The flow hole 21 is located in the center of the noise reduction assembly 20. This structural arrangement, with the flow hole 21 positioned in the center of the noise reduction plate, ensures that the fluid forms a relatively balanced disturbance on both sides of the plate as it passes through it, avoiding uneven distribution caused by lateral flow. This further optimizes the fluid dynamics and improves the consistency and reliability of the noise reduction effect. Furthermore, the central placement of the flow hole 21 fully utilizes the effective area of ​​the noise reduction plate, enhancing the suppression of high-frequency whistling.

[0076] Specifically, along the width W of the noise reduction assembly 20 , the flow hole 21 is provided in the middle of the noise reduction assembly 20 .

[0077] Specifically, the noise reduction component 20 is provided with a flow hole 21 for allowing the fluid to pass through. Among them, the flow hole 21 is a strip hole, and the strip hole is extended along the extension direction of the noise reduction component 20. With such a structural setting, the design of the strip hole increases the longitudinal flow area, reduces the flow resistance of the fluid on the noise reduction component 20, helps to maintain the fluidity of the fluid in the reservoir, and avoids affecting the suction process of the compressor due to excessive resistance. At the same time, the strip hole is arranged along the extension direction of the noise reduction component 20, which can guide the fluid to form turbulence in a specific direction, more effectively destroy the regular airflow pulsation, improve the noise reduction effect, and at the same time reduce the impact and vibration of the fluid flow on the noise reduction component 20, thereby improving the overall performance and stability of the reservoir and the compressor.

[0078] Specifically, the noise reduction component 20 is made of metal. This structural arrangement, using metal as the noise reduction component 20, provides high strength and rigidity, ensuring the stability of the noise reduction component 20 during long-term operation. The metal noise reduction component 20 also creates a more complex interaction with the fluid through its surface microstructure, improving the suppression of airflow pulsation. Furthermore, metal has excellent thermal conductivity, which helps to balance the temperature within the reservoir and improve the overall efficiency of the refrigeration system.

[0079] Specifically, the noise reduction component 20 is made of plastic. With such a structural setting, using plastic material as the noise reduction component 20 can significantly reduce the weight of the internal structure of the liquid reservoir, reduce the burden on the overall design of the liquid reservoir, and help improve the lightweight design of the compressor. The noise reduction component 20 made of plastic material can provide sufficient strength while reducing manufacturing costs and improving production efficiency. In addition, the plastic material has a certain elasticity and can absorb some of the vibrations generated by the impact of the fluid, further reducing the noise level of the liquid reservoir and improving the operating environment of the compressor.

[0080] Specifically, the liquid reservoir also includes an air outlet bend 50 and an air inlet pipe 60. The air inlet pipe 60, the upper cover 101, the main body 102, the lower cover 103 and the air outlet bend 50 are welded and fixed in sequence. In this way, by connecting the various components of the liquid reservoir by welding, the integrity and sealing of the liquid reservoir structure can be ensured, refrigerant leakage can be prevented, and the normal operation of the compressor can be guaranteed. The application of welding technology also improves the mechanical strength of the liquid reservoir, enabling it to withstand the impact of internal high-pressure airflow, reduce vibration and noise during operation, and at the same time ensure the stability of the liquid reservoir under different working conditions, thereby extending the service life of the compressor. This integrated design also simplifies the assembly process, reduces production costs, and improves production efficiency.

[0081] The liquid reservoir also includes a filter assembly 40. The filter assembly 40 is fixedly connected to the inner wall of the cylinder 10. The lower cover 103 has a conical structure. This arrangement facilitates the formation of a flow path after the noise reduction assembly 20 and the intake pipe 30 are assembled, facilitating the flow of fluid through the lower cover 103. The filter assembly 40 is fixedly arranged at one end of the main body 102 near the upper cover 101. The filter assembly 40 is used to filter impurities during air intake. With this structural arrangement, the filter assembly 40 can effectively filter out impurities before the fluid enters the compressor, protecting the internal parts of the compressor from contamination and wear, extending the service life of the compressor, and improving its operating efficiency. The lower cover 103 adopts a conical structure, which can guide the fluid to concentrate in the central area, helping the fluid to form a more regular flow path inside the liquid reservoir, facilitating the installation of the noise reduction assembly 20 and the intake pipe 30. At the same time, it also reduces the turbulence of the fluid, reduces the noise during the fluid flow, optimizes the fluid dynamics characteristics, and improves the refrigerant buffering and gas-liquid separation functions of the liquid reservoir.

[0082] Specifically, an expansion portion 32 is provided at one end of the intake pipe 30 near the air outlet 13, and the expansion portion 32 is welded to the constriction of the lower cover portion 103. With such a structural arrangement, the design of the expansion portion 32 can increase the cross-sectional area of ​​the air flow at the lower portion of the liquid reservoir, effectively slow down the air flow velocity, reduce the impact force of the air flow, and thus reduce the noise caused by air flow pulsation. At the same time, the welding connection between the expansion portion 32 and the constriction of the lower cover portion 103 ensures a firm connection between the intake pipe 30 and the lower portion of the liquid reservoir, avoids shaking and vibration of the intake pipe 30 under high-pressure airflow, and further reduces the noise level during the intake process. This design is also conducive to the uniform distribution of the fluid inside the liquid reservoir, improves the vaporization efficiency of the refrigerant, reduces the risk of liquid refrigerant entering the compressor, and improves the stability of the compressor and the overall performance of the refrigeration system.

[0083] Specifically, the expansion portion 32 is a tubular structure, and the diameter of the expansion portion 32 at one end close to the outlet elbow 50 is larger than the diameter of the expansion portion 32 at one end away from the outlet elbow 50 .

[0084] A second embodiment of the present invention provides a compressor, which includes the liquid storage device provided in the first embodiment.

[0085] The compressor provided by the second embodiment of the present invention can effectively break the airflow pulsation pattern inside the reservoir through the spirally extended noise reduction component 20, reduce or eliminate the modal response of the reservoir excited by the regular airflow pulsation, and thus significantly reduce the high-frequency whistling sound generated by the reservoir during the operation of the compressor. In addition, the spiral structure can make the fluid distribution more uniform while changing the fluid path, reduce the radial movement of the fluid, thereby reducing the impact of the fluid on the cylinder wall and reducing the noise and vibration generated by the fluid flow. On this basis, the spiral setting of the noise reduction component 20 can also optimize the fluid resistance. Through the reasonable design of the noise reduction component 20 (such as pitch, thickness, number of turns), it can be ensured that while suppressing high-frequency noise, the resistance to fluid flow is minimized, and the high-efficiency operation of the reservoir is maintained. Compared with the traditional method of adding additional silencers or changing the size of the reservoir, this design does not require new parts and does not change the external dimensions of the reservoir. Therefore, it can effectively control costs and meet the standardized design requirements of air-conditioning compressors. This configuration is not only suitable for specific compressor models, but also, while maintaining the same reservoir diameter, can be widely applied to different compressors, resolving the high-frequency whistling problem and demonstrating excellent adaptability and versatility. Therefore, the compressor provided in this embodiment can resolve the prior art technical problem of high noise levels within the reservoir.

[0086] Specifically, if Figure 6 and Figure 7 As shown, improvements have been made to a certain existing liquid reservoir (original solution). When the existing liquid reservoir is installed on different compressors, it always presents a prominent noise peak in the range of 2000Hz-2300Hz. Analysis shows that this is due to the radial movement of the fluid in the liquid reservoir. After adopting the noise reduction component 20 of the liquid reservoir in Example 1, the sound transmission loss in the range of 2000Hz-2300Hz has increased significantly, and the increased sound transmission loss is approximately equal to 10dB. The measured noise of the compressor unit in the range of 2000Hz-2300Hz is reduced by 5dB-10dB compared with the original solution. It can be seen that the setting of the noise reduction component 20 has a significant effect in improving noise. It should be noted that, Figure 6 The inlet and outlet of the middle liquid storage device refer to the air intake port 12 and the air outlet port 13 .
