Abstract
Description
Technical Field
[0001] The embodiments of the present invention relate to the field of compressor equipment technology, and more specifically, to a compressor and an air conditioner. Background Technology
[0002] Currently, scroll compressors in related technologies have a check valve structure installed on the stationary plate or the back pressure plate connected to the stationary plate. When the compressor stops, the check valve structure seals the exhaust port on the stationary plate to prevent the compressor from reversing.
[0003] However, the check valve structure increases the exhaust resistance and exhaust pulsation of the airflow, resulting in higher exhaust noise from the scroll compressor. Summary of the Invention
[0004] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.
[0005] Therefore, a first aspect of the embodiments of the present invention provides a compressor.
[0006] A second aspect of the present invention provides an air conditioner.
[0007] In view of the above, according to a first aspect of the present invention, a compressor is provided, the compressor comprising: a housing having an outlet; a partition plate disposed within the housing, the partition plate having a first exhaust port communicating with the outlet; a compression assembly disposed within the housing, the compression assembly including a compression chamber and a second exhaust port communicating with the first exhaust port; and an exhaust check device connected to the side of the partition plate opposite to the second exhaust port, the first check member of the exhaust check device being movable relative to the partition plate; wherein, based on the first check member being in a first position, the first check member seals the first exhaust port or the second exhaust port.
[0008] The compressor provided in this embodiment of the invention includes a housing, a partition plate, a compression assembly, and an exhaust check device. Specifically, the housing is provided with an exhaust port, and the partition plate is disposed inside the housing. It is understood that the partition plate divides the housing into an exhaust chamber and an installation chamber. The compression assembly and other components such as the compressor motor are disposed in the installation chamber, and the exhaust chamber is connected to the exhaust port.
[0009] The partition plate has a first exhaust port, which is connected to the outlet. In other words, the first exhaust port is connected to the outlet through the exhaust chamber. The compression assembly includes a connected compression chamber and a second exhaust port, which are also connected to the first exhaust port. That is, when the compressor discharges gas, the high-temperature, high-pressure gas in the compression chamber is discharged into the exhaust chamber through both the second and first exhaust ports, and finally discharged through the outlet.
[0010] The exhaust check device is connected to the side of the partition plate away from the second exhaust port, meaning that the exhaust check device is located inside the exhaust chamber. Furthermore, the first check element of the exhaust check device can move relative to the partition plate; specifically, the first check element can move relative to the partition plate towards or away from the second exhaust port.
[0011] When the first check valve is in the first position, it seals the first or second exhaust port. In other words, when the first check valve moves to the first position, it can seal the first or second exhaust port. When the compressor stops, sealing the first or second exhaust port with the first check valve effectively reduces the risk of high-temperature, high-pressure airflow flowing out of the compression chamber returning to the compression chamber through the first or second exhaust port, thus preventing the compressor from reversing.
[0012] Furthermore, it is understood that the compressor assembly includes a stationary plate and a moving plate, which together form a compression chamber. A third exhaust port is located on the stationary plate and communicates with the compression chamber. The second exhaust port also communicates with the third exhaust port. In other words, when the compressor discharges gas, the high-temperature, high-pressure gas in the compression chamber is discharged into the exhaust chamber through the third exhaust port, the second exhaust port, and the first exhaust port, respectively, and finally discharged through the outlet. That is, the third exhaust port, the second exhaust port, and the first exhaust port are arranged sequentially from the inside to the outside along the axial direction.
[0013] By placing the exhaust check device on the side of the partition plate away from the second exhaust port, that is, by placing the exhaust check device away from the third exhaust port on the stationary plate, it can reduce the backflow of high-temperature and high-pressure airflow through the second exhaust port into the compression chamber when the compressor stops, thereby causing the compressor to reverse. At the same time, it can significantly reduce the exhaust resistance and exhaust pulsation during the compressor's exhaust process, thereby reducing the airflow noise during exhaust, and thus reducing the overall noise of the compressor. This improves the product quality of air conditioners with this compressor and enhances the user experience.
[0014] Furthermore, by setting the exhaust check device away from the third exhaust port on the stationary plate, the flow path of the airflow during exhaust can be extended, increasing the number of reflections of the airflow during the flow process, thereby significantly improving the noise reduction effect during the compressor's exhaust process.
[0015] In detail, when the compressor discharges, the high-temperature, high-pressure airflow impacts the first check valve, causing it to move away from the second discharge port. This opens either the first or second discharge port, allowing airflow to exit through the second discharge port, the first discharge port, and the outlet, respectively. When the compressor stops, the first check valve moves closer to the second discharge port. When the first check valve reaches its first position, it seals either the first or second discharge port, thus reducing the risk of the high-temperature, high-pressure airflow flowing out of the compression chamber returning to the compression chamber through the first or second discharge port, which could cause the compressor to reverse.
[0016] It should be noted that when the first check valve covers the first or second exhaust port, it can completely or partially cover it. Specifically, the first check valve covers 90% of the first exhaust port or 90% of the second exhaust port. The specific configuration can be adjusted according to actual needs.
[0017] In addition, the compressor provided by the above-described technical solution of the present invention also has the following additional technical features:
[0018] In one possible technical solution, the exhaust backflow prevention device includes a muffler and a backflow prevention assembly. The muffler is connected to the side of the partition plate away from the second exhaust port. The muffler has a muffler cavity. The first exhaust port is connected to the exhaust port through the muffler cavity. The backflow prevention assembly is located on the muffler. The first backflow prevention member of the backflow prevention assembly can move relative to the partition plate within the muffler cavity.
[0019] In this technical solution, the exhaust backflow prevention device is defined to include a muffler frame and a backflow prevention component. Specifically, the muffler frame is connected to the side of the partition plate away from the second exhaust port, and the backflow prevention component is disposed on the muffler frame. Specifically, the backflow prevention component can be connected to the muffler frame, or the backflow prevention component can abut against the muffler frame, thereby realizing the fixed installation of the backflow prevention component and the muffler frame.
[0020] The muffler has a muffler chamber, which is connected to the first exhaust port and the outlet. In other words, when the compressor exhausts, the high-temperature and high-pressure gas in the compression chamber is first discharged into the muffler chamber through the second exhaust port and the first exhaust port for muffler, and finally discharged through the outlet.
[0021] It is understandable that the silencer frame is installed on the outside of the first exhaust port, so that after the high temperature and high pressure airflow enters the silencer cavity through the first exhaust port, a sudden change in cross section occurs, changing the flow path of the airflow, and the sound wave can be reflected multiple times in the silencer cavity, thereby significantly improving the noise reduction effect during the compressor exhaust process.
[0022] The first check valve moves relative to the partition plate within the silencer cavity. Specifically, the first check valve can move away from the second exhaust port under the impact of airflow within the silencer cavity to open either the first or second exhaust port. When the compressor stops, the first check valve moves towards the second exhaust port within the silencer cavity to seal either the first or second exhaust port. By allowing the first check valve to move within the silencer cavity, it is easy for the first check valve to move according to the compressor's exhaust process, eliminating the need for an additional device to drive the movement of the first check valve, simplifying the overall structure of the compressor, and helping to reduce the compressor's production cost.
[0023] The check valve assembly includes a first check valve element, which is movable relative to the partition plate towards or away from the second exhaust port. Specifically, when the compressor discharges, the high-temperature, high-pressure airflow impacts the first check valve element, causing it to move away from the second exhaust port, thus opening either the first or second exhaust port, allowing airflow to exit through the second exhaust port, the first exhaust port, and the outlet, respectively. When the compressor stops, the first check valve element moves towards the second exhaust port. When the first check valve element reaches a first position, it seals the first or second exhaust port, thereby reducing the risk of the high-temperature, high-pressure airflow exiting the compression chamber flowing back into the compression chamber through the first or second exhaust port, which could lead to compressor reversal.
[0024] Furthermore, the silencer frame is connected to the side of the partition plate away from the second exhaust port, and the check valve assembly is located on the silencer frame. In other words, by setting the check valve assembly and the silencer frame away from the third exhaust port on the stationary plate, it is possible to reduce the backflow of high-temperature and high-pressure airflow through the second exhaust port into the compression chamber when the compressor stops, thereby causing the compressor to reverse. At the same time, it significantly reduces the exhaust resistance and exhaust pulsation during the compressor's exhaust process, thereby reducing the airflow noise during exhaust, and thus reducing the overall noise of the compressor. This improves the product quality of air conditioners with this compressor and enhances the user experience.
[0025] Furthermore, by setting the check valve assembly and the muffler away from the third exhaust port on the stationary plate, the flow path of the airflow during exhaust can be extended, increasing the number of reflections of the airflow during the flow process, thereby significantly improving the noise reduction effect during the compressor exhaust process.
[0026] In one possible technical solution, the silencer frame includes a top plate and side plates, wherein a check valve assembly is provided on the top plate, the side plates are connected to the top plate and enclose to form a silencer cavity, and the side plates are connected to a partition plate; the side plates are provided with a connecting part, and the silencer cavity is connected to the air outlet through the connecting part.
[0027] In this technical solution, the muffler frame is defined to include a top plate and a side plate. Specifically, the backflow preventer is located on the top plate, the side plate is connected to the top plate, and the side plate and the top plate enclose a muffler cavity. The muffler frame is fixedly installed by connecting the side plate to the partition plate on the side away from the second exhaust port.
[0028] The side plate is provided with a connecting part, and the silencing cavity is connected to the air outlet through the connecting part. That is to say, the high temperature and high pressure airflow in the compression cavity enters the silencing cavity through the second exhaust port and the first exhaust port respectively, and is discharged into the exhaust cavity through the connecting part on the side plate, and finally discharged through the air outlet.
[0029] By opening a connecting part on the side plate, the high-temperature and high-pressure airflow can enter the silencer chamber through the first exhaust port for noise reduction, while avoiding the airflow directly impacting the top cover of the casing, thereby significantly reducing the impact noise when the compressor is exhausting and further reducing the overall noise of the compressor.
[0030] In practical applications, the connecting part includes multiple connecting holes, which are distributed circumferentially at intervals. This reduces the impact noise during compressor exhaust, while also reducing airflow resistance and exhaust pulsation, further improving the noise reduction during compressor exhaust. Specifically, the number of connecting holes is greater than or equal to four.
[0031] Of course, the connecting part can also include multiple connecting channels, which can be set according to actual needs.
[0032] In one possible technical solution, the connecting part and the air outlet are set separately.
[0033] In this technical solution, the connecting part and the air outlet are staggered. It is understood that the connecting part may include multiple circumferentially spaced connecting holes or multiple circumferentially spaced connecting channels. That is, by staggering each connecting hole or channel from the air outlet, the airflow discharged through the connecting part is prevented from directly exiting through the air outlet during compressor exhaust, increasing the number of airflow reflections within the exhaust chamber and further reducing compressor exhaust noise.
[0034] In one possible technical solution, a portion of the side plate is bent toward the side away from the anechoic chamber to form a connecting part, which is connected to the partition plate.
[0035] In this technical solution, a portion of the side plate is bent towards the side away from the silencing cavity to form a connecting part, which is connected to the side of the partition plate away from the second exhaust port. The bending of a portion of the side plate to form the connecting part facilitates the connection and fixation between the side plate and the partition plate.
[0036] Furthermore, it is understandable that bending a portion of the side panel to form a connecting part, that is, making the connecting part and the side panel an integral structure, can improve the connection strength between the connecting part and the side panel, improve the installation stability of the muffler frame, and thus avoid the problem of the muffler frame falling off the partition plate under the impact of airflow.
[0037] Furthermore, integrating the connecting part with the side plate into a single structure facilitates the production and manufacturing of the muffler frame, thereby improving the production efficiency of the muffler frame and reducing the production costs of the muffler frame and compressor.
[0038] In one possible technical solution, the partition plate and a part of the shell enclose an exhaust chamber, and the connecting part communicates with the air outlet through the exhaust chamber.
[0039] In this technical solution, the partition plate and a part of the housing enclose the exhaust chamber. It can be understood that the partition plate divides the housing into an exhaust chamber and an installation chamber. The compression assembly and the compressor motor and other components are located in the installation chamber, and the exhaust chamber is connected to the air outlet.
[0040] A first exhaust port is provided on the partition plate, and the first exhaust port is connected to the air outlet; that is, the first exhaust port is connected to the air outlet through the exhaust chamber. The compression assembly includes a connected compression chamber and a second exhaust port, and the second exhaust port is connected to the first exhaust port. It is understood that when the compressor discharges, the high-temperature, high-pressure gas in the compression chamber enters the silencer chamber through the second exhaust port and the first exhaust port, respectively, and is discharged into the exhaust chamber through the connecting part on the side plate, finally being discharged through the air outlet.
[0041] During the compressor's exhaust process, the airflow that has been silenced in the silencer chamber is discharged into the exhaust chamber through the connecting part on the side plate. This causes a sudden change in the cross-section, altering the airflow path. Furthermore, the sound waves can be reflected multiple times within the exhaust chamber before finally being discharged through the outlet. This further enhances the silencing effect of the airflow during the exhaust process, thereby reducing the overall noise of the compressor.
[0042] In one possible technical solution, the check valve assembly includes a first check valve and a second check valve, wherein the second check valve is disposed on the top plate, the first check valve is movably disposed on the second check valve, and the first check valve is movable relative to the partition plate on the second check valve.
[0043] In this technical solution, the check valve assembly includes a first check valve and a second check valve. Specifically, the second check valve is disposed on the top plate, and the first check valve is disposed on the second check valve. The first check valve is movable relative to the partition plate on the second check valve. Specifically, the first check valve is movable relative to the second check valve towards the second exhaust port to cover the first or second exhaust port. In addition, the first check valve is also movable relative to the second check valve away from the second exhaust port to open the first or second exhaust port.
[0044] Specifically, when the compressor discharges air, the high-temperature, high-pressure airflow impacts the first check valve, causing it to move away from the second exhaust port on the second check valve. This opens either the first or second exhaust port, allowing airflow to exit through the second exhaust port, the first exhaust port, and the outlet, respectively. When the compressor stops, the first check valve moves towards the second exhaust port on the second check valve. When the first check valve reaches its first position, it seals either the first or second exhaust port, thus reducing the risk of the high-temperature, high-pressure airflow flowing out of the compression chamber returning to the compression chamber through the first or second exhaust port, which could lead to compressor reversal.
[0045] Furthermore, by positioning the check valve assembly and the silencer bracket away from the third exhaust port on the stationary plate, the high-temperature and high-pressure airflow can be reduced from flowing back into the compression chamber through the second exhaust port when the compressor stops, thereby causing the compressor to reverse. At the same time, this significantly reduces the exhaust resistance and exhaust pulsation during the compressor's exhaust process, thereby reducing the airflow noise during exhaust and thus reducing the overall noise of the compressor. This improves the product quality of air conditioners equipped with this compressor and enhances the user experience.
[0046] Furthermore, by setting the check valve assembly and the muffler away from the third exhaust port on the stationary plate, the flow path of the airflow during exhaust can be extended, increasing the number of reflections of the airflow during the flow process, thereby significantly improving the noise reduction effect during the compressor exhaust process.
[0047] In one possible technical solution, the check valve assembly further includes a reflux hole disposed on the second check valve member; wherein, the first check valve member is movable between a first position and a second position, when the first check valve member is in the first position, the first check valve member covers the first exhaust port or the second exhaust port, and the reflux hole connects the exhaust port and the silencer cavity; when the first check valve member is in the second position, the first check valve member closes the reflux hole, and the silencer cavity connects with the first exhaust port and the second exhaust port.
[0048] In this technical solution, the check valve assembly is further defined as including a reflux hole. Specifically, the reflux hole is disposed on the second check valve. Specifically, when the compressor discharges, the high-temperature and high-pressure airflow impacts the first check valve, causing the first check valve to move away from the second exhaust port on the second check valve to open the first exhaust port or the second exhaust port. When the first check valve moves to abut against the second check valve, that is, when the first check valve moves to the second position, the first check valve closes the reflux hole, so that the airflow can only be discharged through the second exhaust port, the first exhaust port and the exhaust port respectively. In other words, the airflow will not be discharged through the reflux hole.
[0049] When the compressor stops, the high-temperature, high-pressure airflow discharged into the exhaust chamber enters the return port, thereby pushing the first check valve to move towards the second check valve towards the second exhaust port, so that the return port is connected to the silencer chamber, that is, the return port is opened. When the first check valve moves to the first position, it seals the first exhaust port or the second exhaust port, thereby reducing the high-temperature, high-pressure airflow flowing out of the compression chamber from flowing back into the compression chamber through the first exhaust port or the second exhaust port, which could lead to the compressor reversing.
[0050] By setting a reflux hole, the first check valve can quickly seal the first or second exhaust port under the impact of high temperature and high pressure airflow, thereby preventing the compressor from reversing when it stops.
[0051] In practical applications, there are multiple reflux holes, which are distributed circumferentially to further ensure that when the compressor stops, the high-temperature and high-pressure airflow can push the first check valve to move quickly toward the second exhaust port through the multiple reflux holes to seal the first or second exhaust port.
[0052] In one possible technical solution, the second check member includes a limiting part and a guiding part, wherein the reflux hole is provided on the limiting part, the limiting part is provided on the top plate, the guiding part is connected to the limiting part, and the first check member can move on the guiding part.
[0053] In this technical solution, the second check valve is defined as including a limiting part and a guiding part. Specifically, the reflux hole is disposed on the limiting part, and the limiting part is disposed on the top plate. The limiting part can be connected to the top plate or abut against the top plate. Specifically, when the compressor discharges, the airflow impacts the first check valve, causing the first check valve to move away from the second discharge port. When the first check valve abuts against the limiting part, the first check valve stops moving and seals the reflux hole.
[0054] The guide portion is connected to the limiting portion, and the first check valve moves on the guide portion towards or away from the second exhaust port. By providing the guide portion, the movement path of the first check valve can be restricted, ensuring that the first check valve will not deviate when impacted by airflow. This ensures that the second exhaust port can be accurately sealed when the compressor stops, thereby reducing the problem of high-temperature and high-pressure airflow flowing out of the compression chamber flowing back into the compression chamber through the first or second exhaust port, which could lead to compressor reversal.
[0055] In practical applications, the limiting part and the guiding part are integrated into a single structure. This integrated structure provides excellent mechanical properties, ensuring the connection strength between the limiting part and the guiding part, and preventing the second check valve from breaking under repeated airflow impacts. Furthermore, the integrated structure facilitates the processing and production of the second check valve, thereby improving production efficiency and reducing production costs.
[0056] In one possible technical solution, the first end of the guide is connected to the limiting part, and the second end of the guide passes through the first exhaust port, or the second end of the guide passes through the first exhaust port and is connected to the compression assembly.
[0057] In this technical solution, two installation methods for the second check element are defined. Specifically, the second check element is connected to the muffler frame, and the second end of the guide portion passes through the first exhaust port, thereby ensuring that the first check element will not detach from the guide portion when it moves on the guide portion, ensuring the stability and reliability of the movement of the first check element, and thus the first check element can effectively seal the first exhaust port or the second exhaust port when the compressor stops.
[0058] The second check valve abuts against the muffler. To fix the second check valve, it passes through the first exhaust port and connects to the compression assembly, thus fixing the second check valve and ensuring that the first check valve does not detach from the guide when it moves on the guide. Therefore, when the compressor stops, the first check valve can effectively seal the first or second exhaust port.
[0059] In one possible technical solution, the compression assembly is provided with a threaded hole, and the second end of the guide is provided with an external thread that mates with the threaded hole; wherein, the second exhaust port is located on the outer side of the threaded hole in the radial direction.
[0060] In this technical solution, the compression assembly is provided with a threaded hole, and the second end of the guide is provided with an external thread. The threaded hole and the external thread cooperate to achieve a fixed connection between the second check valve and the compression assembly. Specifically, the compression assembly includes a back pressure plate, and the back pressure plate is provided with a threaded hole, that is, the guide is connected to the back pressure plate.
[0061] The second vent is located on the outer side of the threaded hole in the radial direction. It is understood that the first check valve is sleeved on the outer side of the guide portion. By placing the second vent on the outer side of the threaded hole in the radial direction, the exhaust resistance of the airflow can be reduced during the movement of the first check valve toward or away from the second vent, thus preventing the second check valve from blocking the exhaust.
[0062] In one possible technical solution, the outer wall of the guide portion is provided with a wear-resistant coating; and / or the outer wall of the guide portion is provided with a smooth coating.
[0063] In this technical solution, the outer wall of the guide part is provided with a wear-resistant coating, which makes the guide part wear-resistant, thereby reducing the wear of the first check valve when it moves repeatedly on the guide part and extending the service life of the second check valve.
[0064] The outer wall of the guide is provided with a smooth coating, thereby reducing the wear of the first check valve when it moves repeatedly on the guide and extending the service life of the second check valve.
[0065] In practical applications, the outer wall of the guide can be coated with DLC, giving it both self-lubricating and wear-resistant properties. The specific configuration can be tailored to individual needs.
[0066] In one possible technical solution, the top plate is provided with a clearance opening, which is connected to the silencing cavity, and the guide part extends into the silencing cavity through the clearance opening; the limiting part is provided with an installation part, which is located outside the silencing cavity and is connected to or abuts against the top plate.
[0067] In this technical solution, the top plate is provided with a clearance opening that communicates with the silencing cavity. The limiting part includes an installation part, which is located on the outside of the silencing cavity. The guide part extends into the silencing cavity through the clearance opening and is connected to or abuts against the top plate through the installation part located on the outside, thereby facilitating the fixed installation of the anti-return assembly and the silencing frame.
[0068] In practical applications, when the mounting part is connected to the top plate, the mounting part is provided with multiple first mounting holes, which are distributed circumferentially. The top plate is provided with multiple second mounting holes at corresponding positions, which are also distributed circumferentially. The compressor also includes multiple fasteners, each of which passes through one first mounting hole and one second mounting hole to fix the mounting part to the muffler frame.
[0069] In one possible technical solution, the first check element includes a check body and a sliding part, wherein the check body is provided with a guide hole, the guide part passes through the guide hole, the sliding part is connected to the side of the check body facing the second exhaust port and is located at the guide hole, and the sliding part is able to move on the guide part.
[0070] In this technical solution, the first check valve is defined as including a check valve body and a sliding part. Specifically, the check valve body is provided with a guide hole, the guide part passes through the guide hole, and the sliding part is connected to the check valve body and located at the guide hole. Specifically, when the compressor discharges, the high-temperature and high-pressure airflow impacts the check valve body, causing the check valve body to drive the sliding part to move away from the second exhaust port on the guide part, so as to open the first exhaust port or the second exhaust port. When the check valve body moves to abut against the limiting part, the check valve body closes the return hole, so that the airflow can only be discharged through the second exhaust port, the first exhaust port, and the outlet, respectively. That is to say, the airflow will not be discharged through the return hole.
[0071] When the compressor stops, the high-temperature and high-pressure airflow discharged into the exhaust chamber enters the return hole, thereby pushing the check body and causing the sliding part to move towards the second exhaust port on the guide part. When the first check part moves to the first position, the check body seals the first exhaust port or the second exhaust port, thereby reducing the high-temperature and high-pressure airflow flowing out of the compression chamber to flow back into the compression chamber through the first exhaust port or the second exhaust port, which could lead to the compressor reversing.
[0072] By setting a sliding part, the first check valve can be prevented from getting stuck during movement, ensuring that the first check valve can promptly seal the first or second exhaust port or promptly open the first or second exhaust port when moving towards or away from the second exhaust port.
[0073] In practical applications, the part of the check valve body near the guide hole is bent outward to form a sliding part, which can be set according to actual needs.
[0074] In one possible technical solution, the exhaust check device further includes a buffer element, which is axially disposed between the muffler and the check assembly.
[0075] In this technical solution, the exhaust check device is further defined as including a buffer component. Specifically, the buffer component is arranged axially between the muffler and the check assembly, thereby effectively absorbing the deformation problem of the partition plate under pressure pulsation and extending the service life of the compressor.
[0076] In practical applications, the buffer component is a sealing gasket, which is located at the connection between the check valve assembly and the muffler frame. This sealing gasket can seal the connection between the check valve assembly and the muffler frame, thereby preventing the high-temperature and high-pressure airflow entering the muffler cavity from leaking through the connection between the check valve assembly and the muffler frame. This ensures that the airflow entering the muffler cavity flows out through the connecting part of the muffler frame side plate, thus ensuring the noise reduction effect of the muffler cavity on the airflow.
[0077] In one possible technical solution, the compression assembly is also provided with multiple exhaust channels, and the compression chamber is connected to the second exhaust port through the multiple exhaust channels.
[0078] In this technical solution, the compression assembly is also provided with multiple exhaust channels. Specifically, the compression chamber is connected to the second exhaust port through multiple exhaust channels. That is to say, when the compressor is venting, the high-temperature and high-pressure airflow in the compression chamber is discharged through the third exhaust port on the stationary plate, and enters the silencer chamber for noise reduction in sequence through multiple exhaust channels, the second exhaust port and the first exhaust port. It is then discharged into the exhaust chamber through the connecting part on the side plate, and finally discharged through the outlet, thus realizing the exhaust process of the compressor.
[0079] By setting up multiple exhaust channels, compared to setting up a single exhaust channel in related technologies, it is possible to reduce exhaust pulsation and exhaust noise generated during the compressor's exhaust process without increasing exhaust resistance, thereby effectively reducing airflow noise during compressor exhaust and further reducing the overall noise during compressor operation.
[0080] Moreover, by setting up multiple exhaust channels, the exhaust resistance of the compressor can be reduced, exhaust efficiency can be ensured, and the stability and reliability of the compressor during operation can be improved.
[0081] In practical applications, at least one of the multiple exhaust channels is located radially outside the second exhaust port. This means the first check valve moves axially towards or away from the second exhaust port to seal or open it. In other words, the check valve assembly is located axially above the second exhaust port. By placing at least one exhaust channel radially outside the second exhaust port, the check valve assembly can effectively prevent obstruction of the exhaust channel, further reducing exhaust resistance and exhaust pulsation, thereby reducing airflow noise during compressor exhaust.
[0082] It is worth noting that multiple exhaust channels can be interconnected or not, depending on actual needs.
[0083] In one possible technical solution, the compression assembly includes a stationary disc, a moving disc, and a back pressure plate, wherein the stationary disc and the moving disc enclose a compression chamber, the stationary disc is provided with a third exhaust port, the third exhaust port is connected to the compression chamber and multiple exhaust channels, the back pressure plate is connected to the side of the stationary disc away from the moving disc, and multiple exhaust channels and a second exhaust port are provided on the back pressure plate; at least two of the multiple exhaust channels are interconnected.
[0084] In this technical solution, the compression assembly is defined as including a stationary disc, a moving disc, and a back pressure plate. Specifically, the stationary disc and the moving disc enclose a compression chamber. It is understood that the compressor also includes a motor and a crankshaft. The crankshaft is connected to the output end of the motor and connected to the moving disc. Driven by the motor, the crankshaft drives the moving disc to rotate relative to the stationary disc, thereby compressing the gas in the compression chamber into a high-temperature and high-pressure gas.
[0085] The silent chamber is equipped with a third exhaust port, which is connected to the compression chamber and multiple exhaust channels. Specifically, when the compressor is venting, the high-temperature and high-pressure gas formed after compression enters the silencer chamber through the third exhaust port, multiple exhaust channels, the second exhaust port and the first exhaust port in sequence, and enters the exhaust chamber through the connecting part, and is finally discharged through the outlet.
[0086] Because the exhaust check device is located on the side of the partition plate away from the second exhaust port, that is, by setting the exhaust check device away from the third exhaust port on the stationary plate, it can reduce the backflow of high-temperature and high-pressure airflow through the second exhaust port into the compression chamber when the compressor stops. This reduces the compressor from reversing and significantly reduces the exhaust resistance and exhaust pulsation during the compressor's exhaust process. This reduces the airflow noise during exhaust, thereby reducing the overall noise of the compressor, improving the product quality of air conditioners with this compressor, and enhancing the user experience.
[0087] Furthermore, by setting the exhaust check device away from the third exhaust port on the stationary plate, the flow path of the airflow during exhaust can be extended, increasing the number of reflections of the airflow during the flow process, thereby significantly improving the noise reduction effect during the compressor's exhaust process.
[0088] The back pressure plate is connected to the side of the stationary plate away from the moving plate. Multiple exhaust channels and a second exhaust port are set on the back pressure plate, and at least two of the multiple exhaust channels are interconnected. This can adapt to different operating conditions of the compressor. That is, regardless of whether the compressor opens the pressure relief valve, it can exhaust through at least two exhaust channels, ensuring stable operation of the compressor while reducing compressor exhaust noise.
[0089] For example, the multiple exhaust passages include a first passage and a second passage that are interconnected. The compression assembly also includes a pressure relief port that communicates with the compression chamber. A pressure relief valve is located on the pressure relief port and can open or close the pressure relief port. The first passage is connected to the second exhaust port and the third exhaust port, and the second passage is connected to the pressure relief port.
[0090] In detail, during compressor operation, when pressure relief is required, the pressure relief valve opens the pressure relief port, and the gas in the compression chamber is discharged through the second channel. When the compressor discharges gas, the pressure relief valve closes the pressure relief port, and the gas in the compression chamber is discharged through the third exhaust port, as well as through the first and second channels.
[0091] It is worth noting that the first channel includes multiple first sub-channels distributed circumferentially, which divert the gas during compressor discharge, thereby reducing discharge pulsation and noise during compressor discharge without increasing discharge resistance, and thus reducing the overall noise of the compressor.
[0092] In practical applications, the cross-sectional shape of each first sub-channel can be U-shaped, and the number of first sub-channels can be greater than or equal to 2, which can be set according to actual needs.
[0093] The second channel includes multiple second sub-channels spaced circumferentially, which divert the gas during compressor discharge, thereby reducing discharge pulsation and noise during compressor discharge without increasing discharge resistance, and thus reducing the overall noise of the compressor.
[0094] In practical applications, the cross-sectional shape of each second sub-channel can be circular, and the number of second sub-channels can be greater than or equal to 2, which can be set according to actual needs.
[0095] Multiple second sub-channels are located radially outside multiple first sub-channels. This prevents the check valve assembly from obstructing the exhaust passage, which could lead to increased exhaust resistance and ensures stable compressor operation.
[0096] In one possible technical solution, the compression assembly further includes a baffle, which is located on the side of the back pressure plate facing the stationary disc and has a gap with the stationary disc, and at least two exhaust passages are interconnected through the gap.
[0097] In this technical solution, the compression assembly further includes a baffle. Specifically, the baffle is located on the side of the back pressure plate facing the stationary disc, and there is a gap between the end of the baffle facing the stationary disc and the stationary disc. At least two exhaust channels are connected through this gap. Reducing the flow cross-sectional area between the at least two exhaust channels allows the airflow to undergo a sudden change in cross-section after passing through the gap, altering the airflow path and further reducing the airflow noise generated during compressor discharge, thereby reducing the overall noise of the compressor.
[0098] The gap h satisfies 0mm ≤ h ≤ 2mm. It's understandable that if this gap is larger, i.e., greater than 2mm, it means that the cross-sectional area for flow between at least two exhaust channels is larger. While this ensures the interconnection between at least two exhaust channels, it reduces the amount of noise reduction during compressor operation, resulting in a lower noise reduction effect.
[0099] According to a second aspect of the present invention, an air conditioner is provided, comprising a compressor as provided by any of the above-described technical solutions, and thus possessing all the beneficial technical effects of the compressor, which will not be elaborated further here.

Detailed Implementation
[0121] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0122] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0123] The following reference Figures 1 to 17 To describe a compressor 100 and an air conditioner provided according to some embodiments of the present invention.
[0124] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a compressor 100 is proposed, comprising: a housing 110, the housing 110 having an air outlet 111; a partition plate 120 disposed within the housing 110, the partition plate 120 having a first exhaust port 121 communicating with the air outlet 111; a compression assembly disposed within the housing 110, the compression assembly including a compression chamber 131 and a second exhaust port 132 communicating with the first exhaust port 121; and an exhaust check device 200 connected to the side of the partition plate 120 opposite to the second exhaust port 132, wherein a first check member 221 of the exhaust check device 200 is movable relative to the partition plate 120; wherein, based on the first check member 221 being in a first position, the first check member 221 covers the first exhaust port 121 or the second exhaust port 132.
[0125] The compressor 100 provided in this embodiment of the invention includes a housing 110, a partition plate 120, a compression assembly, and an exhaust check device 200. Specifically, the housing 110 is provided with an exhaust port 111, and the partition plate 120 is disposed inside the housing 110. It is understood that the partition plate 120 divides the housing 110 into an exhaust chamber 140 and an installation chamber. The compression assembly and components such as the motor of the compressor 100 are disposed in the installation chamber, and the exhaust chamber 140 is connected to the exhaust port 111.
[0126] The partition plate 120 is provided with a first exhaust port 121, which is connected to the outlet 111. That is, the first exhaust port 121 is connected to the outlet 111 through the exhaust chamber 140. The compression assembly includes a connected compression chamber 131 and a second exhaust port 132, which is connected to the first exhaust port 121. In other words, when the compressor 100 discharges gas, the high-temperature and high-pressure gas in the compression chamber 131 is discharged into the exhaust chamber 140 through the second exhaust port 132 and the first exhaust port 121, and finally discharged through the outlet 111.
[0127] The exhaust check device 200 is connected to the side of the partition plate 120 away from the second exhaust port 132, that is, the exhaust check device 200 is disposed in the exhaust chamber 140. Moreover, the first check member 221 of the exhaust check device 200 can move relative to the partition plate 120. Specifically, the first check member 221 can move relative to the partition plate 120 in a direction closer to or away from the second exhaust port 132.
[0128] When the first check valve 221 is in the first position, it seals the first exhaust port 121 or the second exhaust port 132. Specifically, in some embodiments, when the first check valve 221 moves to the first position, it can seal the first exhaust port 121. Thus, when the compressor 100 stops, sealing the first exhaust port 121 with the first check valve 221 can effectively reduce the problem of high-temperature and high-pressure airflow flowing out of the compression chamber 131 flowing back into the compression chamber 131 through the first exhaust port 121, thereby preventing the compressor 100 from reversing.
[0129] In other embodiments, the first check valve 221 can pass through the first exhaust port 121 to cover the second exhaust port 132. That is, when the first check valve 221 is in the first position, it can cover the second exhaust port 132. Thus, when the compressor 100 stops, by covering the second exhaust port 132 with the first check valve 221, the problem of the high-temperature and high-pressure airflow flowing out of the compression chamber 131 flowing back into the compression chamber 131 through the second exhaust port 132, thereby causing the compressor 100 to reverse, can be effectively reduced.
[0130] Furthermore, it is understood that the compressor 100 assembly includes a stationary plate 133 and a moving plate 134, which together form a compression chamber 131. A third exhaust port 136 is provided on the stationary plate 133, communicating with the compression chamber 131. A second exhaust port 132 communicates with the third exhaust port 136. That is, when the compressor 100 discharges gas, the high-temperature, high-pressure gas in the compression chamber 131 is discharged into the exhaust chamber 140 through the third exhaust port 136, the second exhaust port 132, and the first exhaust port 121, respectively, and finally discharged through the outlet port 111. In other words, the third exhaust port 136, the second exhaust port 132, and the first exhaust port 121 are arranged sequentially from the inside to the outside along the axial direction.
[0131] By positioning the exhaust check device 200 on the side of the partition plate 120 away from the second exhaust port 132, that is, by positioning the exhaust check device 200 away from the third exhaust port 136 on the stationary plate 133, the high-temperature and high-pressure airflow can be reduced from flowing back into the compression chamber 131 through the second exhaust port 132 when the compressor 100 stops. This reduces the exhaust resistance and exhaust pulsation during the compressor 100's exhaust process, thereby reducing the airflow noise during exhaust and the overall noise of the compressor 100. This improves the product quality of the air conditioner with the compressor 100 and enhances the user experience.
[0132] Furthermore, by setting the exhaust check device 200 away from the third exhaust port 136 on the stationary plate 133, the flow path of the airflow during exhaust can be extended, and the number of reflections of the airflow during the flow process can be increased, thereby significantly improving the noise reduction effect of the compressor 100 during the exhaust process.
[0133] In detail, when the compressor 100 discharges, the high-temperature, high-pressure airflow impacts the first check valve 221, causing it to move away from the second exhaust port 132. This opens either the first exhaust port 121 or the second exhaust port 132, allowing airflow to exit through the second exhaust port 132, the first exhaust port 121, and the outlet 111, respectively. When the compressor 100 stops, the first check valve 221 moves closer to the second exhaust port 132. When the first check valve 221 reaches the first position, it seals either the first exhaust port 121 or the second exhaust port 132, thereby reducing the risk of the high-temperature, high-pressure airflow exiting the compression chamber 131 flowing back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0134] It should be noted that when the first check valve 221 seals the first exhaust port 121 or the second exhaust port 132, it can completely cover the first exhaust port 121 or the second exhaust port 132, or it can partially cover it. Specifically, the first check valve 221 covers 90% of the first exhaust port 121 or 90% of the second exhaust port 132. The specific settings can be configured according to actual needs.
[0135] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on the above embodiment, the exhaust check device 200 further includes a muffler frame 210 and a check assembly 220. The muffler frame 210 is connected to the side of the partition plate 120 away from the second exhaust port 132. The muffler frame 210 is provided with a muffler cavity 211. The first exhaust port 121 is connected to the exhaust port 111 through the muffler cavity 211. The check assembly 220 is provided on the muffler frame 210. The first check member 221 of the check assembly 220 can move relative to the partition plate 120 within the muffler cavity 211.
[0136] In this embodiment, the exhaust backflow prevention device 200 includes a muffler frame 210 and a backflow prevention component 220. Specifically, the muffler frame 210 is connected to the side of the partition plate 120 away from the second exhaust port 132, and the backflow prevention component 220 is disposed on the muffler frame 210. Specifically, the backflow prevention component 220 can be connected to the muffler frame 210, or the backflow prevention component 220 abuts against the muffler frame 210, thereby achieving the fixed installation of the backflow prevention component 220 and the muffler frame 210.
[0137] The silencer frame 210 has a silencer cavity 211, which is connected to the first exhaust port 121 and the air outlet 111. That is, when the compressor 100 exhausts, the high temperature and high pressure gas in the compression chamber 131 is first discharged into the silencer cavity 211 through the second exhaust port 132 and the first exhaust port 121 for silence, and finally discharged through the air outlet 111.
[0138] It is understandable that the silencer frame 210 is installed on the outside of the first exhaust port 121, so that after the high temperature and high pressure airflow enters the silencer cavity 211 through the first exhaust port 121, a sudden change in cross section can occur, changing the flow path of the airflow, and the sound wave can be reflected multiple times in the silencer cavity 211, thereby significantly improving the noise reduction effect of the compressor 100 during the exhaust process.
[0139] The first check valve 221 moves relative to the partition plate 120 within the silencer 211. Specifically, the first check valve 221 can move away from the second exhaust port 132 under the impact of airflow to open either the first exhaust port 121 or the second exhaust port 132. When the compressor 100 stops, the first check valve 221 moves towards the second exhaust port 132 to seal either the first exhaust port 121 or the second exhaust port 132. By moving the first check valve 221 within the silencer 211, it is convenient for the first check valve 221 to move according to the exhaust process of the compressor 100, eliminating the need for an additional device to drive the movement of the first check valve 221, simplifying the overall structure of the compressor 100, and helping to reduce the production cost of the compressor 100.
[0140] The check valve assembly 220 includes a first check valve 221, which is movable relative to the partition plate 120 towards or away from the second exhaust port 132. Specifically, when the compressor 100 discharges, the high-temperature, high-pressure airflow impacts the first check valve 221, causing it to move away from the second exhaust port 132 to open either the first exhaust port 121 or the second exhaust port 132, allowing airflow to be discharged through the second exhaust port 132, the first exhaust port 121, and the outlet 111, respectively. When the compressor 100 stops, the first check valve 221 moves towards the second exhaust port 132. When the first check valve 221 moves to the first position, it seals either the first exhaust port 121 or the second exhaust port 132, thereby reducing the problem of the high-temperature, high-pressure airflow flowing out of the compression chamber 131 flowing back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0141] Furthermore, the silencer frame 210 is connected to the side of the partition plate 120 away from the second exhaust port 132, and the check valve assembly 220 is disposed on the silencer frame 210. That is to say, by setting the check valve assembly 220 and the silencer frame 210 away from the third exhaust port 136 on the stationary plate 133, when the compressor 100 stops, the high-temperature and high-pressure airflow can be reduced from flowing back into the compression chamber 131 through the second exhaust port 132, thereby causing the compressor 100 to reverse. At the same time, it can significantly reduce the exhaust resistance and exhaust pulsation during the exhaust process of the compressor 100, thereby reducing the airflow noise during exhaust, and thus reducing the overall noise of the compressor 100, improving the product quality of the air conditioner with the compressor 100, and improving the user experience.
[0142] Furthermore, by setting the check valve assembly 220 and the silencer 210 away from the third exhaust port 136 on the stationary plate 133, the flow path of the airflow during exhaust can be extended, and the number of reflections of the airflow during the flow process can be increased, thereby significantly improving the noise reduction effect of the compressor 100 during the exhaust process.
[0143] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiment, the silencer frame 210 further includes a top plate 212 and a side plate 213, wherein the check valve assembly 220 is disposed on the top plate 212, the side plate 213 is connected to the top plate 212 and surrounds to form a silencer cavity 211, and the side plate 213 is connected to the partition plate 120; the side plate 213 is provided with a connecting part 214, and the silencer cavity 211 is connected to the air outlet 111 through the connecting part 214.
[0144] In this embodiment, the muffler frame 210 is defined to include a top plate 212 and a side plate 213. Specifically, the backflow preventer assembly 220 is disposed on the top plate 212, the side plate 213 is connected to the top plate 212, and the side plate 213 and the top plate 212 enclose a muffler cavity 211. The muffler frame 210 is fixedly installed by connecting the side plate 213 to the side of the partition plate 120 away from the second exhaust port 132.
[0145] The side plate 213 is provided with a connecting part 214, and the silencing cavity 211 is connected to the air outlet 111 through the connecting part 214. That is to say, the high temperature and high pressure airflow in the compression cavity 131 enters the silencing cavity 211 through the second exhaust port 132 and the first exhaust port 121 respectively, and is discharged into the exhaust cavity 140 through the connecting part 214 on the side plate 213, and finally discharged through the air outlet 111.
[0146] By opening a connecting part 214 on the side plate 213, the high-temperature and high-pressure airflow can enter the silencing cavity 211 through the first exhaust port 121 for silencing, while avoiding the airflow directly impacting the top cover of the housing 110, thereby significantly reducing the impact noise when the compressor 100 is venting, and further reducing the overall noise of the compressor 100.
[0147] In practical applications, the connecting part 214 includes multiple connecting holes that are spaced apart circumferentially. This reduces the impact noise during the exhaust process of the compressor 100, while also reducing the exhaust resistance and pulsation of the airflow, further improving the noise reduction during the exhaust process of the compressor 100. Specifically, the number of connecting holes is greater than or equal to four.
[0148] Of course, the connecting part 214 may also include multiple connecting channels, which can be set according to actual needs.
[0149] Based on the above embodiments, the connecting part 214 is further offset from the air outlet 111.
[0150] In this embodiment, the connecting portion 214 is staggered from the air outlet 111. It is understood that the connecting portion 214 may include multiple circumferentially spaced connecting holes or multiple circumferentially spaced connecting channels. That is, by staggering each connecting hole or channel from the air outlet 111, the airflow discharged through the connecting portion 214 is prevented from directly exiting through the air outlet 111 when the compressor 100 is discharging exhaust gas. This increases the number of reflections of the airflow within the exhaust chamber 140, further reducing the exhaust noise of the compressor 100.
[0151] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiment, a portion of the side plate 213 is further bent toward the side away from the silencing cavity 211 to form a connecting portion 216, which is connected to the partition plate 120.
[0152] In this embodiment, a portion of the side plate 213 is bent toward the side opposite to the silencing cavity 211 to form a connecting portion 216, which is connected to the side of the partition plate 120 opposite to the second exhaust port 132. The connecting portion 216 is formed by bending a portion of the side plate 213, which facilitates the connection and fixation between the side plate 213 and the partition plate 120.
[0153] Furthermore, it is understandable that bending a portion of the side plate 213 to form the connecting part 216 means that the connecting part 216 and the side plate 213 are an integral structure, which can improve the connection strength between the connecting part 216 and the side plate 213, improve the installation stability of the muffler 210, and thus avoid the problem of the muffler 210 falling off the partition plate 120 under the impact of airflow.
[0154] Furthermore, by making the connecting part 216 and the side plate 213 an integral structure, it is easier to manufacture the muffler frame 210, thereby improving the production efficiency of the muffler frame 210 and reducing the production cost of the muffler frame 210 and the compressor 100.
[0155] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, based on the above embodiment, the partition plate 120 and a part of the housing 110 further enclose an exhaust chamber 140, and the connecting part 214 communicates with the air outlet 111 through the exhaust chamber 140.
[0156] In this embodiment, the partition plate 120 and a part of the housing 110 enclose an exhaust chamber 140. It is understood that the partition plate 120 divides the housing 110 into an exhaust chamber 140 and an installation cavity. The compression assembly and the motor of the compressor 100 are located in the installation cavity. The exhaust chamber 140 is connected to the air outlet 111.
[0157] The partition plate 120 is provided with a first exhaust port 121, which is connected to the air outlet 111. That is, the first exhaust port 121 is connected to the air outlet 111 through the exhaust chamber 140. The compression assembly includes a connected compression chamber 131 and a second exhaust port 132, which is connected to the first exhaust port 121. It can be understood that when the compressor 100 discharges, the high-temperature and high-pressure gas in the compression chamber 131 enters the silencer chamber 211 through the second exhaust port 132 and the first exhaust port 121, respectively, and is discharged into the exhaust chamber 140 through the connecting part 214 on the side plate 213, and finally discharged through the air outlet 111.
[0158] During the exhaust process of the compressor 100, when the airflow that has been silenced by entering the silencer 211 is discharged to the exhaust chamber 140 through the connecting part 214 on the side plate 213, a sudden change in cross section can occur, changing the flow path of the airflow. The sound wave can be reflected multiple times in the exhaust chamber 140 and finally discharged through the outlet 111, thereby further improving the silencer effect of the airflow during the exhaust process and reducing the overall noise of the compressor 100.
[0159] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, based on the above embodiment, the check valve assembly 220 further includes a first check valve 221 and a second check valve 222, wherein the second check valve 222 is disposed on the top plate 212, the first check valve 221 is movably disposed on the second check valve 222, and the first check valve 221 is movable relative to the partition plate 120 on the second check valve 222.
[0160] In this embodiment, the check valve assembly 220 is defined to include a first check valve 221 and a second check valve 222. Specifically, the second check valve 222 is disposed on the top plate 212, and the first check valve 221 is disposed on the second check valve 222. The first check valve 221 is movable relative to the partition plate 120 on the second check valve 222. Specifically, the first check valve 221 is movable relative to the second check valve 222 toward the second exhaust port 132 to cover the first exhaust port 121 or the second exhaust port 132. In addition, the first check valve 221 is also movable relative to the second check valve 222 away from the second exhaust port 132 to open the first exhaust port 121 or the second exhaust port 132.
[0161] Specifically, when the compressor 100 discharges, the high-temperature, high-pressure airflow impacts the first check valve 221, causing it to move away from the second exhaust port 132 on the second check valve 222. This opens either the first exhaust port 121 or the second exhaust port 132, allowing airflow to exit through the second exhaust port 132, the first exhaust port 121, and the outlet 111, respectively. When the compressor 100 stops, the first check valve 221 moves towards the second exhaust port 132 on the second check valve 222. When the first check valve 221 reaches the first position, it seals either the first exhaust port 121 or the second exhaust port 132, thereby reducing the risk of the high-temperature, high-pressure airflow exiting the compression chamber 131 flowing back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0162] Furthermore, by positioning the check valve assembly 220 and the silencer bracket 210 away from the third exhaust port 136 on the stationary plate 133, when the compressor 100 stops, the high-temperature and high-pressure airflow can be reduced from flowing back into the compression chamber 131 through the second exhaust port 132, thereby causing the compressor 100 to reverse. At the same time, this significantly reduces the exhaust resistance and exhaust pulsation during the exhaust process of the compressor 100, thereby reducing the airflow noise during exhaust, and thus reducing the overall noise of the compressor 100. This improves the product quality of the air conditioner with the compressor 100 and enhances the user experience.
[0163] Furthermore, by setting the check valve assembly 220 and the silencer 210 away from the third exhaust port 136 on the stationary plate 133, the flow path of the airflow during exhaust can be extended, and the number of reflections of the airflow during the flow process can be increased, thereby significantly improving the noise reduction effect of the compressor 100 during the exhaust process.
[0164] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, based on the above embodiment, the check valve assembly 220 further includes a reflux hole 223, which is disposed on the second check valve 222; wherein, the first check valve 221 is movable between a first position and a second position. When the first check valve 221 is in the first position, the first check valve 221 covers the first exhaust port 121 or the second exhaust port 132, and the reflux hole 223 connects the exhaust port 111 and the silencing cavity 211; when the first check valve 221 is in the second position, the first check valve 221 closes the reflux hole 223, and the silencing cavity 211 connects with the first exhaust port 121 and the second exhaust port 132.
[0165] In this embodiment, the check valve assembly 220 further includes a return hole 223. Specifically, the return hole 223 is disposed on the second check valve 222. Specifically, when the compressor 100 discharges, the high-temperature and high-pressure airflow impacts the first check valve 221, causing the first check valve 221 to move away from the second exhaust port 132 on the second check valve 222, thereby opening the first exhaust port 121 or the second exhaust port 132. When the first check valve 221 moves to abut against the second check valve 222, that is, when the first check valve 221 moves to the second position, the first check valve 221 closes the return hole 223, so that the airflow can only be discharged through the second exhaust port 132, the first exhaust port 121 and the exhaust port 111 respectively. In other words, the airflow will not be discharged through the return hole 223.
[0166] When the compressor 100 stops, the high-temperature and high-pressure airflow discharged into the exhaust chamber 140 enters the return hole 223, thereby pushing the first check valve 221 to move towards the second exhaust port 132 on the second check valve 222, so that the return hole 223 communicates with the silencer 211, that is, the return hole 223 is opened. When the first check valve 221 moves to the first position, it seals the first exhaust port 121 or the second exhaust port 132, thereby reducing the problem of the high-temperature and high-pressure airflow flowing out of the compression chamber 131 flowing back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0167] By setting the return hole 223, under the impact of high temperature and high pressure airflow, the first check valve 221 can quickly seal the first exhaust port 121 or the second exhaust port 132, thereby preventing the compressor 100 from reversing when it stops.
[0168] In practical applications, there are multiple return holes 223, which are distributed circumferentially to further ensure that when the compressor 100 stops, the high-temperature and high-pressure airflow can push the first check valve 221 to move quickly toward the second exhaust port 132 through the multiple return holes 223 to seal the first exhaust port 121 or the second exhaust port 132.
[0169] like Figure 6 and Figure 8 As shown, based on the above embodiment, the second check valve 222 further includes a limiting part 2221 and a guiding part 2222, wherein the reflux hole 223 is provided on the limiting part 2221, the limiting part 2221 is provided on the top plate 212, the guiding part 2222 is connected to the limiting part 2221, and the first check valve 221 can move on the guiding part 2222.
[0170] In this embodiment, the second check valve 222 is defined as including a limiting portion 2221 and a guiding portion 2222. Specifically, the reflux hole 223 is disposed on the limiting portion 2221, and the limiting portion 2221 is disposed on the top plate 212. Specifically, when the compressor 100 discharges, the airflow impacts the first check valve 221, causing the first check valve 221 to move away from the second exhaust port 132. When the first check valve 221 abuts against the limiting portion 2221, the first check valve 221 stops moving and seals the reflux hole 223.
[0171] The guide portion 2222 is connected to the limiting portion 2221, and the first check valve 221 moves on the guide portion 2222 towards or away from the second exhaust port 132. By providing the guide portion 2222, the movement path of the first check valve 221 can be restricted, ensuring that the first check valve 221 will not deviate under the impact of airflow, thereby ensuring that the compressor 100 can accurately seal the second exhaust port 132 when it stops, thereby reducing the problem that the high-temperature and high-pressure airflow flowing out of the compression chamber 131 will flow back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0172] In practical applications, the limiting part 2221 and the guide part 2222 are integrated into a single structure. This integrated structure provides excellent mechanical properties, ensuring the connection strength between the limiting part 2221 and the guide part 2222, and preventing the second check valve 222 from breaking under repeated airflow impacts. Furthermore, the integrated structure facilitates the processing and production of the second check valve 222, thereby improving production efficiency and reducing production costs.
[0173] like Figure 2 and Figure 4 As shown, in a specific embodiment, the first end of the guide portion 2222 is further connected to the limiting portion 2221, and the second end of the guide portion 2222 passes through the first exhaust port 121, or the second end of the guide portion 2222 passes through the first exhaust port 121 and is connected to the compression assembly.
[0174] In this embodiment, two installation methods for the second check valve 222 are defined. Specifically, the second check valve 222 is connected to the muffler 210, and the second end of the guide portion 2222 passes through the first exhaust port 121, thereby ensuring that the first check valve 221 will not detach from the guide portion 2222 when it moves on the guide portion 2222, ensuring the stability and reliability of the movement of the first check valve 221. Thus, when the compressor 100 stops, the first check valve 221 can effectively seal the first exhaust port 121 or the second exhaust port 132.
[0175] The second check valve 222 abuts against the muffler 210. To fix the second check valve 222, the second check valve 222 passes through the first exhaust port 121 and connects to the compression assembly, thereby fixing the second check valve 222. It also ensures that the first check valve 221 will not detach from the guide portion 2222 when it moves on the guide portion 2222. Thus, when the compressor 100 stops, the first check valve 221 can effectively seal the first exhaust port 121 or the second exhaust port 132.
[0176] In another specific embodiment, the compression assembly is further provided with a threaded hole, and the second end of the guide portion 2222 is provided with an external thread, which mates with the threaded hole; wherein, the second exhaust port 132 is located on the outer side of the threaded hole in the radial direction.
[0177] In this embodiment, the compression assembly is provided with a threaded hole, and the second end of the guide portion 2222 is provided with an external thread. The threaded hole and the external thread cooperate to achieve a fixed connection between the second check valve 222 and the compression assembly. Specifically, the compression assembly includes a back pressure plate 135, and the back pressure plate 135 is provided with a threaded hole, that is, the guide portion 2222 is connected to the back pressure plate 135.
[0178] The second vent 132 is located on the outer side of the threaded hole in the radial direction. It is understood that the first check valve 221 is sleeved on the outer side of the guide portion 2222. By placing the second vent 132 on the outer side of the threaded hole in the radial direction, the exhaust resistance of the airflow can be reduced during the movement of the first check valve 221 toward or away from the second vent 132, thus preventing the second check valve 222 from blocking the exhaust.
[0179] In yet another specific embodiment, the outer wall of the guide portion 2222 is provided with a wear-resistant coating; and / or the outer wall of the guide portion 2222 is provided with a smooth coating.
[0180] In this embodiment, the outer wall of the guide portion 2222 is provided with a wear-resistant coating, thereby giving the guide portion 2222 wear-resistant properties, thereby reducing the wear of the first check valve 221 when it moves repeatedly on the guide portion 2222, and extending the service life of the second check valve 222.
[0181] The outer wall of the guide portion 2222 is provided with a smooth coating, thereby reducing the wear of the first check valve 221 when it moves repeatedly on the guide portion 2222 and extending the service life of the second check valve 222.
[0182] In practical applications, the outer wall of the guide portion 2222 can be coated with a DLC coating, which gives the outer wall of the guide portion 2222 both self-lubricating and wear-resistant properties. The specific configuration can be made according to actual needs.
[0183] like Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, based on the above embodiment, the top plate 212 is further provided with a clearance opening 215, which is connected to the silencing cavity 211. The guide part 2222 extends into the silencing cavity 211 through the clearance opening 215. The limiting part 2221 is provided with a mounting part 224, which is located outside the silencing cavity 211 and is connected to or abuts against the top plate 212.
[0184] In this embodiment, the top plate 212 is provided with a clearance opening 215 that communicates with the silencing cavity 211. The limiting part 2221 includes a mounting part 224, which is located on the outside of the silencing cavity 211. The guide part 2222 extends into the silencing cavity 211 through the clearance opening 215 and is connected to or abuts against the top plate 212 through the mounting part 224 located on the outside, thereby facilitating the fixed installation of the backflow prevention assembly 220 and the silencing frame 210.
[0185] In practical applications, the mounting part 224 is provided with a plurality of first mounting holes, which are distributed circumferentially. The top plate 212 is provided with a plurality of second mounting holes at corresponding positions, which are also distributed circumferentially. The compressor 100 also includes a plurality of fasteners, each of which passes through a first mounting hole and a second mounting hole to fix the mounting part 224 to the silencer frame 210.
[0186] like Figure 9 As shown, based on the above embodiment, the first check valve 221 further includes a check valve body 2211 and a sliding part 2212. The check valve body 2211 is provided with a guide hole 2213, the guide part 2222 passes through the guide hole 2213, the sliding part 2212 is connected to the side of the check valve body 2211 facing the second exhaust port 132 and is located at the guide hole 2213, and the sliding part 2212 can move on the guide part 2222.
[0187] In this embodiment, the first check valve 221 is defined as including a check valve body 2211 and a sliding part 2212. Specifically, the check valve body 2211 is provided with a guide hole 2213, the guide part 2222 passes through the guide hole 2213, the sliding part 2212 is connected to the check valve body 2211, and the sliding part 2212 is located at the guide hole 2213. Specifically, when the compressor 100 discharges, the high-temperature and high-pressure airflow impacts the check body 2211, causing the check body 2211 to drive the sliding part 2212 to move away from the second exhaust port 132 on the guide part 2222, so as to open the first exhaust port 121 or the second exhaust port 132. When the check body 2211 moves to abut against the limiting part 2221, the check body 2211 closes the return hole 223, so that the airflow can only be discharged through the second exhaust port 132, the first exhaust port 121 and the outlet 111 respectively. In other words, the airflow will not be discharged through the return hole 223.
[0188] When the compressor 100 stops, the high-temperature and high-pressure airflow discharged into the exhaust chamber 140 enters the return hole 223, thereby pushing the check body 2211 and causing the sliding part 2212 to move towards the second exhaust port 132 on the guide part 2222. When the first check member 221 moves to the first position, the check body 2211 covers the first exhaust port 121 or the second exhaust port 132, thereby reducing the high-temperature and high-pressure airflow flowing out of the compression chamber 131 from flowing back into the compression chamber 131 through the first exhaust port 121 or the second exhaust port 132, which could lead to the compressor 100 reversing.
[0189] By providing the sliding part 2212, the first check valve 221 can be prevented from getting stuck during movement, ensuring that the first check valve 221 can promptly seal the first exhaust port 121 or the second exhaust port 132, or promptly open the first exhaust port 121 or the second exhaust port 132 when moving towards or away from the second exhaust port 132.
[0190] In practical applications, the portion of the check body 2211 near the guide hole 2213 is bent outward to form a sliding part 2212, which can be set according to actual needs.
[0191] like Figure 2 and Figure 4 As shown, based on the above embodiments, the exhaust check device 200 further includes a buffer 230, which is axially disposed between the muffler frame 210 and the check assembly 220.
[0192] In this embodiment, the exhaust check device 200 is further defined as including a buffer 230. Specifically, the buffer 230 is axially disposed between the muffler 210 and the check assembly 220, thereby effectively absorbing the deformation problem of the partition plate 120 under pressure pulsation and extending the service life of the compressor 100.
[0193] In practical applications, the buffer 230 is a sealing gasket. The sealing gasket is located at the connection between the check component 220 and the muffler frame 210, thereby sealing the connection between the check component 220 and the muffler frame 210. This prevents the high-temperature and high-pressure airflow entering the muffler cavity 211 from leaking through the connection between the check component 220 and the muffler frame 210, ensuring that the airflow entering the muffler cavity 211 flows out through the connecting part 214 of the side plate 213 of the muffler frame 210, thereby ensuring the noise reduction effect of the muffler cavity 211 on the airflow.
[0194] like Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, based on any of the above embodiments, the compression assembly is further provided with multiple exhaust channels 150, and the compression chamber 131 is connected to the second exhaust port 132 through the multiple exhaust channels 150.
[0195] In this embodiment, the compression assembly is further provided with multiple exhaust channels 150. Specifically, the compression chamber 131 is connected to the second exhaust port 132 through multiple exhaust channels 150. That is, when the compressor 100 exhausts, the high-temperature and high-pressure airflow in the compression chamber 131 is discharged through the third exhaust port 136 on the stationary plate 133, and enters the silencer chamber 211 for noise reduction in sequence through multiple exhaust channels 150, the second exhaust port 132 and the first exhaust port 121. It is then discharged into the exhaust chamber 140 through the connecting part 214 on the side plate 213, and finally discharged through the air outlet 111, thus realizing the exhaust process of the compressor 100.
[0196] By setting multiple exhaust channels 150, compared with setting a single exhaust channel 150 in related technologies, it is possible to reduce the exhaust pulsation and exhaust noise generated during the exhaust process of the compressor 100 without increasing exhaust resistance, thereby effectively reducing the airflow noise during the exhaust of the compressor 100 and further reducing the overall noise during the operation of the compressor 100.
[0197] Furthermore, by setting up multiple exhaust channels 150, the exhaust resistance of the compressor 100 can be reduced, exhaust efficiency can be ensured, and the stability and reliability of the compressor 100 during operation can be improved.
[0198] In practical applications, at least one of the multiple exhaust channels 150 is located radially outside the second exhaust port 132. It is understood that the first check valve 221 moves axially towards or away from the second exhaust port 132 to cover or open it. That is, the check valve assembly 220 is located axially above the second exhaust port 132. By placing at least one exhaust channel 150 radially outside the second exhaust port 132, the check valve assembly 220 can effectively prevent obstruction of the exhaust channel 150, further reducing exhaust resistance and exhaust pulsation, thereby reducing airflow noise during the compressor 100's exhaust process.
[0199] It is worth noting that the multiple exhaust channels 150 can be interconnected or not, depending on the actual needs.
[0200] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 14 , Figure 15 , Figure 16 and Figure 17 As shown, based on the above embodiment, the compression assembly further includes a stationary disc 133, a moving disc 134, and a back pressure plate 135. The stationary disc 133 and the moving disc 134 enclose a compression cavity 131. The stationary disc 133 is provided with a third exhaust port 136, which communicates with the compression cavity 131 and a plurality of exhaust channels 150. The back pressure plate 135 is connected to the side of the stationary disc 133 away from the moving disc 134. A plurality of exhaust channels 150 and a second exhaust port 132 are provided on the back pressure plate 135. At least two of the plurality of exhaust channels 150 are interconnected.
[0201] In this embodiment, the compression assembly is defined as including a stationary disc 133, a moving disc 134, and a back pressure plate 135. Specifically, the stationary disc 133 and the moving disc 134 enclose a compression chamber 131. It is understood that the compressor 100 also includes a motor and a crankshaft. The crankshaft is connected to the output end of the motor and connected to the moving disc 134. Driven by the motor, the crankshaft drives the moving disc 134 to rotate relative to the stationary disc 133, thereby compressing the gas in the compression chamber 131 so that the gas in the compression chamber 131 is compressed into a high-temperature and high-pressure gas.
[0202] The silent plate 133 is equipped with a third exhaust port 136, which is connected to the compression chamber 131 and multiple exhaust channels 150. Specifically, when the compressor 100 exhausts, the high-temperature and high-pressure gas formed after compression enters the silencer 211 through the third exhaust port 136, multiple exhaust channels 150, the second exhaust port 132 and the first exhaust port 121 in sequence, and enters the exhaust chamber 140 through the connecting part 214, and is finally discharged through the outlet 111.
[0203] Since the exhaust check device 200 is located on the side of the partition plate 120 away from the second exhaust port 132, that is, by setting the exhaust check device 200 away from the third exhaust port 136 on the stationary plate 133, it can reduce the backflow of high-temperature and high-pressure airflow through the second exhaust port 132 into the compression chamber 131 when the compressor 100 stops. This causes the compressor 100 to reverse while significantly reducing the exhaust resistance and exhaust pulsation during the exhaust process of the compressor 100, thereby reducing the airflow noise during exhaust, and thus reducing the overall noise of the compressor 100, improving the product quality of the air conditioner with the compressor 100, and enhancing the user experience.
[0204] Furthermore, by setting the exhaust check device 200 away from the third exhaust port 136 on the stationary plate 133, the flow path of the airflow during exhaust can be extended, and the number of reflections of the airflow during the flow process can be increased, thereby significantly improving the noise reduction effect of the compressor 100 during the exhaust process.
[0205] The back pressure plate 135 is connected to the side of the stationary plate 133 away from the moving plate 134. Multiple exhaust channels 150 and a second exhaust port 132 are provided on the back pressure plate 135, and at least two of the multiple exhaust channels 150 are interconnected, which can adapt to different operating conditions of the compressor 100. That is, regardless of whether the compressor 100 opens the pressure relief valve, it can exhaust through at least two exhaust channels 150, ensuring the stable operation of the compressor 100 while reducing the exhaust noise of the compressor 100.
[0206] For example, the multiple exhaust passages 150 include a first passage and a second passage that are interconnected. The compression assembly also includes a pressure relief port that communicates with the compression chamber 131. A pressure relief valve is provided on the pressure relief port and can open or close the pressure relief port. The first passage is connected to the second exhaust port 132 and the third exhaust port 136, and the second passage is connected to the pressure relief port.
[0207] In detail, during the operation of compressor 100, when pressure relief is required, the pressure relief valve opens the pressure relief port, and the gas in compression chamber 131 is discharged through the second channel. When compressor 100 discharges gas, the pressure relief valve closes the pressure relief port, and the gas in compression chamber 131 is discharged through the third exhaust port 136 and through the first and second channels.
[0208] It is worth noting that the first channel includes multiple first sub-channels distributed circumferentially, which divert the gas when the compressor 100 is discharging. This reduces the exhaust pulsation and noise during the exhaust process of the compressor 100 without increasing the exhaust resistance, thereby reducing the overall noise of the compressor 100.
[0209] In practical applications, the cross-sectional shape of each first sub-channel can be U-shaped, and the number of first sub-channels can be greater than or equal to 2, which can be set according to actual needs.
[0210] The second channel includes multiple second sub-channels distributed circumferentially, which divert the gas during the exhaust of the compressor 100. This reduces exhaust pulsation and exhaust noise during the exhaust process of the compressor 100 without increasing exhaust resistance, thereby reducing the overall noise of the compressor 100.
[0211] In practical applications, the cross-sectional shape of each second sub-channel can be circular, and the number of second sub-channels can be greater than or equal to 2, which can be set according to actual needs.
[0212] Multiple second sub-channels are located radially outside multiple first sub-channels. This prevents the check valve assembly 220 from obstructing the exhaust passage 150, which could lead to increased exhaust resistance and ensures stable operation of the compressor 100.
[0213] like Figure 2 , Figure 4 , Figure 15 and Figure 17 As shown, based on the above embodiment, the compression assembly further includes a baffle 137, which is disposed on the side of the back pressure plate 135 facing the stationary plate 133 and has a gap 138 between it and the stationary plate 133. At least two exhaust channels 150 are interconnected through the gap 138.
[0214] In this embodiment, the compression assembly further includes a flange 137. Specifically, the flange 137 is disposed on the side of the back pressure plate 135 facing the stationary plate 133, and a gap 138 exists between the end of the flange 137 facing the stationary plate 133 and the stationary plate 133. At least two exhaust channels 150 are connected through this gap 138. Reducing the flow cross-sectional area between the at least two exhaust channels 150 allows the airflow to undergo a sudden change in cross-section after exiting through the gap 138, altering the airflow path and further reducing the airflow noise generated when the compressor 100 discharges, thereby reducing the overall noise of the compressor 100.
[0215] When the compressor 100 discharges, the high-temperature and high-pressure airflow in the compression chamber 131 is discharged through the third exhaust port 136 on the stationary plate 133 and enters the first channel. Part of the high-temperature and high-pressure airflow enters the second channel through the gap 138. The airflow flowing out through the first channel and the second channel converges at the second exhaust port 132 and impacts the first check valve 221, thereby causing the first check valve 221 to move away from the second exhaust port 132 on the second check valve 222 to open the second exhaust port 132. When the first check valve 221 moves to abut against the second check valve 222, the first check valve 221 closes the return hole 223, so that the airflow can only be discharged through the second exhaust port 132, the first exhaust port 121 and the outlet 111 respectively. That is to say, the airflow will not be discharged through the return hole 223.
[0216] When the compressor 100 stops, the high-temperature and high-pressure airflow discharged into the exhaust chamber 140 enters the return hole 223, thereby pushing the check body 2211 and causing the sliding part 2212 to move towards the second exhaust port 132 on the guide part 2222. When the first check member 221 moves to the first position, the check body 2211 covers the second exhaust port 132, thereby reducing the high-temperature and high-pressure airflow flowing out of the compression chamber 131 from flowing back into the compression chamber 131 through the second exhaust port 132, which would cause the compressor 100 to reverse.
[0217] The gap 138h satisfies the condition 0mm ≤ h ≤ 2mm. It is understandable that if the gap 138h is larger, i.e., greater than 2mm, it means that the cross-sectional area for interconnection between at least two exhaust channels 150 is larger. While this ensures interconnection between at least two exhaust channels 150, it reduces the noise reduction during compressor 100 operation, resulting in a lower noise reduction effect.
[0218] According to a second aspect of the present invention, an air conditioner is provided, comprising a compressor 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the compressor 100, which will not be repeated here.
[0219] In practical applications, the compressor 100 defined in this application includes, but is not limited to, a scroll compressor 100.
