Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and more specifically, to an exhaust valve assembly, a stationary disk assembly, a compressor, and a refrigeration device. Background Art

[0002] Currently, a scroll compressor includes a moving scroll and a stationary scroll. The moving scroll performs a translational motion relative to the stationary scroll. During the translational motion, the volume of the pressure chamber formed between the moving scroll and the stationary scroll gradually decreases, thereby achieving the purpose of gas compression.

[0003] In the related art of scroll compressors, generally, a reed exhaust valve is provided at the exhaust port of the stationary scroll to prevent the reverse flow of high-pressure gas from causing the scroll to reverse during the shutdown process of the scroll compressor, and to prevent the frequent backflow of high-pressure gas into the pressure chamber under under-compression conditions, resulting in repeated compression problems. However, when the reed valve plate opens the through-hole on the discharge valve plate, there is a problem of relatively large viscous force, increasing the power consumption of the compressor. Summary of the Utility Model

[0004] The embodiments of the present utility model aim to at least solve one of the technical problems existing in the prior art.

[0005] For this reason, in the first aspect of the embodiments of the present utility model, an exhaust valve assembly is provided.

[0006] In the second aspect of the embodiments of the present utility model, a stationary disk assembly is provided.

[0007] In the third aspect of the embodiments of the present utility model, a compressor is provided.

[0008] In the fourth aspect of the embodiments of the present utility model, a refrigeration device is provided.

[0009] In view of this, according to the first aspect of the embodiments of the present utility model, an exhaust valve assembly is provided. The exhaust valve assembly is used for a stationary scroll plate, and the stationary scroll plate is provided with an exhaust port. The exhaust valve assembly includes: a valve plate, the valve plate is provided with a through-hole, and the first end of the through-hole is used to communicate with the exhaust port; a valve piece, arranged on the valve plate, for opening or closing the second end of the through-hole; wherein, at least one groove is provided on the side surface of the valve plate facing the valve piece.

[0010] The exhaust valve assembly provided by the embodiments of the present utility model includes a valve plate and a valve piece. Specifically, the stationary scroll plate is provided with an exhaust port. Optionally, the compressor further includes a moving scroll plate, and the moving scroll plate and the stationary scroll plate enclose a compression chamber, and the compression chamber is communicated with the exhaust port. Specifically, the moving scroll plate can perform translational rotation relative to the stationary scroll plate to compress the gas in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure gas is discharged from the exhaust port.

[0011] The valve plate is provided with a through hole. The first end of the through hole communicates with the exhaust port. The valve piece can open or close the second end of the through hole. That is to say, the lower end of the through hole communicates with the exhaust port, and the valve piece is used to open or close the upper end of the through hole so as to conduct or cut off the discharge passage.

[0012] Specifically, during the operation of the compressor, the compressed high-temperature and high-pressure gas flows through the exhaust port and the through hole in sequence, impacting the valve piece to open the second end of the through hole, and the discharge passage is conducted to achieve exhaust. When the compressor stops, the valve piece closes the second end of the through hole, and the discharge passage is cut off to avoid the situation that the compressor reverses due to the backflow of high-pressure air flow. In addition, when the compressor is in an under-compression working condition, by closing the second end of the through hole with the valve piece, it can effectively prevent the high-pressure gas from frequently flowing back into the compression chamber, thereby avoiding the problem of repeated compression and improving the efficiency of the compressor.

[0013] At least one groove is provided on one side of the valve plate facing the valve piece. That is to say, at least one groove is provided on the contact surface between the valve plate and the valve piece, so as to effectively reduce the contact area between the side of the valve plate facing the valve piece and the valve piece, significantly reduce the viscous force between the valve piece and the surface of the valve plate when the valve piece opens the second end of the through hole, and thus is beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0014] Moreover, it can be understood that during the exhaust process, a certain amount of high-temperature and high-pressure gas will be contained in at least one groove. When the valve piece closes the second end of the through hole, it can generate a certain buffering force on the valve piece, thereby effectively slowing down the speed of the valve piece hitting the surface of the valve plate, reducing the noise generated when the valve piece closes the second end of the through hole, and thus being beneficial to reducing the overall noise of the compressor.

[0015] In addition, the exhaust valve assembly provided by the above technical solution of the present invention also has the following additional technical features:

[0016] In some technical solutions, optionally, the number of grooves is multiple.

[0017] In this technical solution, the number of grooves is limited to be multiple. That is to say, a plurality of grooves are provided on the contact surface between the valve plate and the valve piece, so as to further reduce the contact area between the side of the valve plate facing the valve piece and the valve piece, significantly reduce the viscous force between the valve piece and the surface of the valve plate when the valve piece opens the second end of the through hole, and thus is beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0018] Moreover, during the exhaust process, a certain amount of high-temperature and high-pressure gas will be contained in the multiple grooves. When the valve piece closes the second end of the through hole, it can generate a certain buffering force on the valve piece, thereby further slowing down the speed of the valve piece hitting the surface of the valve plate, reducing the noise generated when the valve piece closes the second end of the through hole, and thus being beneficial to reducing the overall noise of the compressor.

[0019] In some technical solutions, optionally, at least one groove communicates with the through hole.

[0020] In this technical solution, it is defined that at least one groove communicates with the through hole. Optionally, the number of grooves is 3. One of the grooves communicates with the through hole, and the other two grooves do not communicate with the through hole, or two of the grooves communicate with the through hole, and the other groove does not communicate with the through hole, or each groove communicates with the through hole. Specifically, it can be set according to actual needs.

[0021] Since at least one groove communicates with the through hole, during the exhaust process, the high-temperature and high-pressure gas flowing out of the through hole can enter at least one groove, thereby increasing the impact force on the valve plate, further reducing the viscous force between the valve plate and the valve plate surface when the valve plate opens the second end of the through hole, enabling the valve plate to quickly open the second end of the through hole, and thus being beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0022] In some technical solutions, optionally, the exhaust valve assembly further includes at least one support rib. At least one support rib is provided in the through hole and divides the through hole into at least two sub-holes, and each sub-hole is used to communicate with the exhaust port.

[0023] In this technical solution, it is defined that the exhaust valve assembly further includes at least one support rib. Specifically, at least one support rib is disposed in the through hole, and at least one support rib divides the through hole into at least two sub-holes, that is, a support structure is formed in the through hole. Thus, when the valve plate closes the second end of the through hole, the downward concave deformation of the valve plate at the through hole position can be effectively reduced, which is beneficial to reducing the local stress of the valve plate, prolonging the service life of the valve plate, and improving the reliability of the valve plate.

[0024] Moreover, since at least one support rib divides the through hole into at least two sub-holes, and each sub-hole communicates with the exhaust port, when the valve plate opens the second end of the through hole for exhaust, it can play a role in dispersing the high-pressure air flow, effectively reducing the torsional deformation and flutter of the valve plate, and further improving the reliability of the valve plate.

[0025] It can be understood that by reasonably designing the size and position of the multiple sub-holes, the magnitude of the impact force of the air flow acting on the valve plate and the position of the air flow acting on the valve plate can be adjusted.

[0026] In some technical solutions, optionally, at least one groove is provided on at least one support rib.

[0027] In this technical solution, it is defined that at least one groove is provided on at least one support rib. Since at least one support rib is disposed in the through hole, and the movable end of the valve plate can open or close the through hole to realize the conduction or cut-off of the discharge path, that is, at least one support rib is close to the movable end of the valve plate.

[0028] By arranging the groove on the support rib, that is, arranging the groove at a position close to the movable end of the valve plate, the contact area between the movable end of the valve plate and the valve plate is reduced, which can further reduce the viscous force between the valve plate and the valve plate surface when the valve plate opens the second end of the through hole, thereby facilitating the reduction of the power consumption of the compressor and improving the energy efficiency of the compressor.

[0029] Moreover, by arranging the groove on the support rib, compared with arranging the groove at other positions far from the through hole, the high-pressure gas can quickly enter the groove to form a buffer structure, so as to slow down the speed of the valve plate hitting the valve plate surface and reduce the noise generated when the valve plate closes the second end of the through hole.

[0030] In some technical solutions, optionally, the number of support ribs is multiple, and the multiple support ribs divide the through hole into multiple sub-holes, and each sub-hole is used to communicate with the exhaust port.

[0031] In this technical solution, the number of support ribs is limited to be multiple. Specifically, since the multiple support ribs are located in the through hole, a support structure is formed in the through hole. When the valve plate closes the second end of the through hole, the downward concave deformation of the valve plate at the through hole position can be further reduced, which is beneficial to reducing the local stress of the valve plate, improving the strength of the valve plate, prolonging the service life of the valve plate, and enhancing the reliability of the valve plate.

[0032] Since the multiple support ribs divide the through hole into multiple sub-holes, and each sub-hole communicates with the exhaust port, when the valve plate opens the second end of the through hole for exhaust, it can play a role in dispersing the high-pressure air flow, effectively reducing the torsional deformation and flutter of the valve plate, and further enhancing the reliability of the valve plate.

[0033] In some technical solutions, optionally, the number n of sub-holes satisfies n≥3.

[0034] In this technical solution, the value range of the number of sub-holes is limited. Specifically, the number of sub-holes is greater than or equal to 3.

[0035] It can be understood that when the number of support ribs is multiple, the through hole can be divided into at least three sub-holes. Since the multiple support ribs are located in the through hole, a support structure is formed in the through hole. When the valve plate closes the second end of the through hole, the downward concave deformation of the valve plate at the through hole position can be further reduced, which is beneficial to reducing the local stress of the valve plate, improving the strength of the valve plate, prolonging the service life of the valve plate, and enhancing the reliability of the valve plate.

[0036] In addition, by reasonably designing the size and position of the multiple sub-holes, the magnitude of the impact force of the air flow acting on the valve plate and the position of the air flow acting on the valve plate can be adjusted.

[0037] In some technical solutions, optionally, the flow-through areas of at least some of the sub-holes are equal; or the flow-through areas of at least some of the sub-holes are different.

[0038] In this technical solution, the flow areas of at least some of the sub-holes are equal. Alternatively, the flow areas of at least some of the sub-holes are different. Specifically, it can be set according to actual needs. It can be understood that by reasonably designing the sizes and positions of multiple sub-holes, the magnitude of the impact force of the airflow acting on the valve plate and the position where the airflow acts on the valve plate can be adjusted.

[0039] In addition, since at least one support rib divides the through-hole into at least two sub-holes, and each sub-hole communicates with the exhaust port, when the valve plate opens the second end of the through-hole for exhaust, it can play a role in dispersing the high-pressure airflow, effectively reducing the torsional deformation and flutter of the valve plate, and further improving the reliability of the valve plate.

[0040] In some technical solutions, optionally, the exhaust valve assembly further includes a limiter, and the limiter is located on the side of the valve plate away from the valve plate and is connected to the valve plate and the valve plate.

[0041] In this technical solution, it is defined that the exhaust valve assembly further includes a limiter. Specifically, the limiter is provided on the side of the valve plate away from the valve plate. That is to say, the valve plate is located between the valve plate and the limiter.

[0042] By providing the limiter, when the valve plate opens the second end of the through-hole, the valve plate can be limited, avoiding the problem that the valve plate is damaged due to excessive deformation under the impact of high-temperature and high-pressure gas, ensuring that the valve plate effectively seals the second end of the through-hole, and avoiding gas backflow or reverse flow, which is beneficial to extending the service life of the valve plate.

[0043] Optionally, connection holes are respectively provided at one end of the valve plate, one end of the valve plate, one end of the limiter, and the stationary scroll. The compressor further includes a screw, and the screw sequentially passes through the connection holes on the limiter, the connection holes on the valve plate, the connection holes on the valve plate, and the connection holes on the stationary scroll, thereby fixing the limiter, the valve plate, and the valve plate on the stationary scroll.

[0044] According to the second aspect of the present invention, a stationary plate assembly is provided, including the exhaust valve assembly provided in any of the above technical solutions, and thus has all the beneficial technical effects of the exhaust valve assembly, which will not be elaborated here.

[0045] Furthermore, the stationary plate assembly further includes a stationary scroll, the stationary scroll is provided with an exhaust port, and the valve plate is located between the stationary scroll and the valve plate.

[0046] The stationary disk assembly provided by the embodiment of the present utility model includes a stationary scroll disk and an exhaust valve assembly. Specifically, optionally, the compressor further includes a moving scroll disk, and the moving scroll disk and the stationary scroll disk enclose a compression chamber, and the compression chamber is communicated with an exhaust port. Specifically, the moving scroll disk can perform translational rotation relative to the stationary scroll disk to compress the gas in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure gas is discharged from the exhaust port.

[0047] The valve plate is provided with a through hole, and the first end of the through hole is communicated with the exhaust port. The valve piece can open or close the second end of the through hole. That is to say, the lower end of the through hole is communicated with the exhaust port, and the valve piece is used to open or close the upper end of the through hole to make the discharge passage conduct or cut off.

[0048] Specifically, during the operation of the compressor, the compressed high-temperature and high-pressure gas flows through the exhaust port and the through hole in sequence, impacts the valve piece, so that the valve piece opens the second end of the through hole, and the discharge passage conducts to realize exhaust. When the compressor stops running, the valve piece closes the second end of the through hole, and the discharge passage cuts off to avoid the situation that the compressor reverses due to the backflow of high-pressure air flow. In addition, when the compressor is in an under-compression working condition, by closing the second end of the through hole with the valve piece, it can effectively avoid the frequent backflow of high-pressure gas into the compression chamber, thereby causing the problem of repeated compression and improving the efficiency of the compressor.

[0049] At least one groove is provided on the side surface of the valve plate facing the valve piece. That is to say, at least one groove is provided on the contact surface between the valve plate and the valve piece, so as to effectively reduce the contact area between the side surface of the valve plate facing the valve piece and the valve piece, and significantly reduce the viscous force between the valve piece and the surface of the valve plate when the valve piece opens the second end of the through hole, thereby being beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0050] Moreover, it can be understood that during the exhaust process, a certain amount of high-temperature and high-pressure gas will be contained in at least one groove. When the valve piece closes the second end of the through hole, it can generate a certain buffering force on the valve piece, so as to effectively slow down the speed of the valve piece slapping the surface of the valve plate, reduce the noise generated when the valve piece closes the second end of the through hole, and thus be beneficial to reducing the overall noise of the compressor.

[0051] According to the third aspect of the present utility model, a compressor is provided, which includes the exhaust valve assembly or the stationary disk assembly provided by any of the above technical solutions, and thus has all the beneficial technical effects of the exhaust valve assembly or the stationary disk assembly, which will not be elaborated here.

[0052] According to the fourth aspect of the present utility model, a refrigeration device is provided, which includes the exhaust valve assembly, the stationary disk assembly or the compressor provided by any of the above technical solutions, and thus has all the beneficial technical effects of the exhaust valve assembly, the stationary disk assembly or the compressor, which will not be elaborated here.

[0064] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0065] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present utility model is not limited by the specific embodiments disclosed below.

[0066] Reference is now made to Figures 1 to 7 describe an exhaust valve assembly 100, a stationary disk assembly 200, a compressor, and a refrigeration device provided according to some embodiments of the present utility model.

[0067] In one embodiment according to the present application, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, an exhaust valve assembly 100 is proposed. The exhaust valve assembly 100 is for a stationary scroll 210 which is provided with an exhaust port 211. The exhaust valve assembly 100 includes: a valve plate 110 which is provided with a through hole 111, and a first end 112 of the through hole 111 is used to communicate with the exhaust port 211; a valve piece 120 which is arranged on the valve plate 110 and is used to open or close a second end 113 of the through hole 111; wherein, at least one groove 114 is provided on a side surface of the valve plate 110 facing the valve piece 120.

[0068] The exhaust valve assembly 100 provided by the embodiments of the present utility model includes a valve plate 110 and a valve piece 120. Specifically, the stationary scroll 210 is provided with an exhaust port 211. Optionally, the compressor further includes a moving scroll, and the moving scroll and the stationary scroll 210 enclose a compression chamber which is communicated with the exhaust port 211. Specifically, the moving scroll can perform translational rotation relative to the stationary scroll 210 to compress the gas in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 211.

[0069] The valve plate 110 is provided with a through hole 111, and a first end 112 of the through hole 111 is communicated with the exhaust port 211. The valve piece 120 can open or close a second end 113 of the through hole 111. That is to say, the lower end of the through hole 111 is communicated with the exhaust port 211, and the valve piece 120 is used to open or close the upper end of the through hole 111 so as to conduct or cut off the discharge path.

[0070] Specifically, during the operation of the compressor, the high-temperature and high-pressure gas after compression flows through the exhaust port 211 and the through hole 111 in sequence, impacting the valve plate 120 to open the second end 113 of the through hole 111 by the valve plate 120, conducting the discharge passage, and realizing exhaust. When the compressor stops, the valve plate 120 closes the second end 113 of the through hole 111, and the discharge passage is cut off to avoid the situation that the compressor reverses due to the backflow of high-pressure air flow. In addition, when the compressor is in an under-compression working condition, by closing the second end 113 of the through hole 111 by the valve plate 120, it can effectively prevent the high-pressure gas from frequently flowing back into the compression cavity, thereby avoiding the problem of repeated compression and improving the compressor efficiency.

[0071] At least one groove 114 is provided on one side surface of the valve plate 110 facing the valve plate 120, that is to say, at least one groove 114 is provided on the contact surface between the valve plate 110 and the valve plate 120, so as to effectively reduce the contact area between one side surface of the valve plate 110 facing the valve plate 120 and the valve plate 120, significantly reduce the viscous force between the valve plate 120 and the surface of the valve plate 110 when the valve plate 120 opens the second end 113 of the through hole 111, and thus is beneficial to reducing the power consumption of the compressor, improving the energy efficiency of the compressor, and improving the starting ability of the compressor to start with load.

[0072] Moreover, it can be understood that during the exhaust process, a certain amount of high-temperature and high-pressure gas will be contained in at least one groove 114. When the valve plate 120 closes the second end 113 of the through hole 111, it can generate a certain buffering force on the valve plate 120, so as to effectively slow down the speed of the valve plate 120 hitting the surface of the valve plate 110, reduce the noise generated when the valve plate 120 closes the second end 113 of the through hole 111, and thus is beneficial to reducing the overall noise of the compressor.

[0073] Such as Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, the number of grooves 114 is multiple.

[0074] In this embodiment, the number of grooves 114 is limited to be multiple, that is to say, a plurality of grooves 114 are provided on the contact surface between the valve plate 110 and the valve plate 120, so as to further reduce the contact area between one side surface of the valve plate 110 facing the valve plate 120 and the valve plate 120, significantly reduce the viscous force between the valve plate 120 and the surface of the valve plate 110 when the valve plate 120 opens the second end 113 of the through hole 111, and thus is beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0075] Moreover, during the exhaust process, a certain amount of high-temperature and high-pressure gas will be contained in the multiple grooves 114. When the valve plate 120 closes the second end 113 of the through hole 111, it can generate a certain buffering force on the valve plate 120, thereby further slowing down the speed of the valve plate 120 hitting the surface of the valve plate 110, reducing the noise generated when the valve plate 120 closes the second end 113 of the through hole 111, and further facilitating the reduction of the overall noise of the compressor.

[0076] Optionally, the shapes of the multiple grooves 114 can be the same or different. Specifically, it can be set according to actual needs.

[0077] Such as Figure 1 、 Figure 2 and Figure 3 As shown in

[0078] In this embodiment, it is defined that at least one groove 114 communicates with the through hole 111. Optionally, the number of grooves 114 is 3. One of the grooves 114 communicates with the through hole 111, and the other two grooves 114 do not communicate with the through hole 111, or two of the grooves 114 communicate with the through hole 111, and the other one groove 114 does not communicate with the through hole 111, or each groove 114 communicates with the through hole 111. Specifically, it can be set according to actual needs.

[0079] Since at least one groove 114 communicates with the through hole 111, during the exhaust process, the high-temperature and high-pressure gas flowing out of the through hole 111 can enter at least one groove 114, thereby increasing the impact force on the valve plate 120, further reducing the viscous force between the valve plate 120 and the surface of the valve plate 110 when the valve plate 120 opens the second end 113 of the through hole 111, enabling the valve plate 120 to quickly open the second end 113 of the through hole 111, and further facilitating the reduction of the power consumption of the compressor and improving the energy efficiency of the compressor.

[0080] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in

[0081] In this embodiment, it is defined that the exhaust valve assembly 100 further includes at least one support rib 130. Specifically, at least one support rib 130 is disposed in the through hole 111, and at least one support rib 130 divides the through hole 111 into at least two sub-holes 140. That is to say, a support structure is formed in the through hole 111. Thus, when the valve plate 120 closes the second end 113 of the through hole 111, the downward concave deformation of the valve plate 120 at the position of the through hole 111 can be effectively reduced, which is beneficial to reducing the local stress of the valve plate 120, prolonging the service life of the valve plate 120, and improving the reliability of the valve plate 120.

[0082] Moreover, since at least one support rib 130 divides the through hole 111 into at least two sub-holes 140, and each sub-hole 140 communicates with the exhaust port 211, when the valve plate 120 opens the second end 113 of the through hole 111 for exhaust, it can play a role in dispersing the high-pressure air flow, effectively reducing the torsional deformation and flutter of the valve plate 120, and further improving the reliability of the valve plate 120.

[0083] It can be understood that by reasonably designing the size and position of the multiple sub-holes 140, the magnitude of the impact force of the air flow acting on the valve plate 120 and the position where the air flow acts on the valve plate 120 can be adjusted.

[0084] Such as Figure 1 、 Figure 2 and Figure 3 shown, in some embodiments, optionally, at least one groove 114 is provided on at least one support rib 130.

[0085] In this embodiment, it is defined that at least one groove 114 is provided on at least one support rib 130. Since at least one support rib 130 is disposed in the through hole 111, and the movable end of the valve plate 120 can open or close the through hole 111 to achieve the conduction or cut-off of the discharge passage. That is to say, at least one support rib 130 is close to the movable end of the valve plate 120.

[0086] By providing the groove 114 on the support rib 130, that is, providing the groove 114 at a position close to the movable end of the valve plate 120, to reduce the contact area between the movable end of the valve plate 120 and the valve plate 110, the viscous force between the valve plate 120 and the surface of the valve plate 110 when the valve plate 120 opens the second end 113 of the through hole 111 can be further reduced, which is beneficial to reducing the power consumption of the compressor and improving the energy efficiency of the compressor.

[0087] Moreover, by providing the groove 114 on the support rib 130, compared with providing the groove 114 at other positions far from the through hole 111, the high-pressure gas can quickly enter the groove 114 to form a buffer structure, so as to slow down the speed of the valve plate 120 hitting the surface of the valve plate 110 and reduce the noise generated when the valve plate 120 closes the second end 113 of the through hole 111.

[0088] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, in some embodiments, optionally, the number of the support ribs 130 is multiple, and the multiple support ribs 130 divide the through hole 111 into multiple sub-holes 140, and each sub-hole 140 is used to communicate with the exhaust port 211.

[0089] In this embodiment, the number of the support ribs 130 is limited to be multiple. Specifically, since the multiple support ribs 130 are located in the through hole 111, a support structure is formed in the through hole 111. When the valve plate 120 closes the second end 113 of the through hole 111, the downward concave deformation of the valve plate 120 at the position of the through hole 111 can be further reduced, which is beneficial to reducing the local stress of the valve plate 120, improving the strength of the valve plate 120, prolonging the service life of the valve plate 120, and enhancing the reliability of the valve plate 120.

[0090] Since the multiple support ribs 130 divide the through hole 111 into multiple sub-holes 140, and each sub-hole 140 communicates with the exhaust port 211, when the valve plate 120 opens the second end 113 of the through hole 111 for exhausting, it can play a role in dispersing the high-pressure air flow, effectively reducing the torsional deformation and flutter of the valve plate 120, and further enhancing the reliability of the valve plate 120.

[0091] As Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, in some embodiments, optionally, the number n of the sub-holes 140 satisfies n≥3.

[0092] In this embodiment, the value range of the number of the sub-holes 140 is limited. Specifically, the number of the sub-holes 140 is greater than or equal to 3.

[0093] It can be understood that when the number of the support ribs 130 is multiple, the through hole 111 can be divided into at least three sub-holes 140. Since the multiple support ribs 130 are located in the through hole 111, a support structure is formed in the through hole 111. When the valve plate 120 closes the second end 113 of the through hole 111, the downward concave deformation of the valve plate 120 at the position of the through hole 111 can be further reduced, which is beneficial to reducing the local stress of the valve plate 120, improving the strength of the valve plate 120, prolonging the service life of the valve plate 120, and enhancing the reliability of the valve plate 120.

[0094] In addition, by reasonably designing the sizes and positions of the multiple sub-holes 140, the magnitude of the impact force of the air flow acting on the valve plate 120 and the position of the air flow acting on the valve plate 120 can be adjusted.

[0095] In some embodiments, optionally, the flow areas of at least some of the sub-holes 140 are equal; or the flow areas of at least some of the sub-holes 140 are different.

[0096] In this embodiment, the flow areas of at least some of the sub-holes 140 are equal. Alternatively, the flow areas of at least some of the sub-holes 140 are different. Specifically, it can be set according to actual needs. It can be understood that by reasonably designing the sizes and positions of the multiple sub-holes 140, the magnitude of the impact force of the airflow acting on the valve plate 120 and the position where the airflow acts on the valve plate 120 can be adjusted.

[0097] In addition, since at least one support rib 130 divides the through-hole 111 into at least two sub-holes 140, and each sub-hole 140 communicates with the exhaust port 211, when the valve plate 120 opens the second end 113 of the through-hole 111 for exhaust, it can play a role in dispersing the high-pressure airflow, effectively reducing the torsional deformation and flutter of the valve plate 120, and further improving the reliability of the valve plate 120.

[0098] As Figure 1 and Figure 4 shown, in some embodiments, optionally, the exhaust valve assembly 100 further includes a limiter 150. The limiter 150 is located on the side of the valve plate 120 facing away from the valve plate 110 and is connected to the valve plate 120 and the valve plate 110.

[0099] In this embodiment, it is defined that the exhaust valve assembly 100 further includes a limiter 150. Specifically, the limiter 150 is arranged on the side of the valve plate 120 facing away from the valve plate 110. That is to say, the valve plate 120 is located between the valve plate 110 and the limiter 150.

[0100] By providing the limiter 150, when the valve plate 120 opens the second end 113 of the through-hole 111, the valve plate 120 can be limited, avoiding the problem that the valve plate 120 is damaged due to excessive deformation under the impact of high-temperature and high-pressure gas, ensuring that the valve plate 120 effectively closes the second end 113 of the through-hole 111, avoiding gas backflow or reverse flow, and being beneficial to extending the service life of the valve plate 120.

[0101] Optionally, connection holes are respectively provided at one end of the valve plate 110, one end of the valve plate 120, one end of the limiter 150, and the stationary scroll 210. The compressor further includes screws. The screws sequentially pass through the connection holes on the limiter 150, the connection holes on the valve plate 120, the connection holes on the valve plate 110, and the connection holes on the stationary scroll 210, thereby fixing the limiter 150, the valve plate 120, and the valve plate 110 on the stationary scroll 210.

[0102] According to the second aspect of the present utility model, a stationary disk assembly 200 is provided, which includes the exhaust valve assembly 100 provided in any of the above embodiments, and thus has all the beneficial technical effects of the exhaust valve assembly 100, which will not be elaborated here.

[0103] As Figure 1 and Figure 4 shown, further, the stationary disk assembly 200 further includes a stationary scroll 210, the stationary scroll 210 is provided with an exhaust port 211, and the valve plate 110 is located between the stationary scroll 210 and the valve piece 120.

[0104] The stationary disk assembly 200 provided by the embodiment of the present utility model includes a stationary scroll 210 and an exhaust valve assembly 100. Specifically, optionally, the compressor further includes a moving scroll, and the moving scroll and the stationary scroll 210 enclose a compression chamber, and the compression chamber is communicated with the exhaust port 211. Specifically, the moving scroll can perform translational rotation relative to the stationary scroll 210 to compress the gas in the compression chamber. When the exhaust pressure is reached, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 211.

[0105] The valve plate 110 is provided with a through hole 111, the first end 112 of the through hole 111 is communicated with the exhaust port 211, and the valve piece 120 can open or close the second end 113 of the through hole 111. That is to say, the lower end of the through hole 111 is communicated with the exhaust port 211, and the valve piece 120 is used to open or close the upper end of the through hole 111 to make the discharge passage conduct or cut off.

[0106] Specifically, during the operation of the compressor, the compressed high-temperature and high-pressure gas flows through the exhaust port 211 and the through hole 111 in sequence, impacts the valve piece 120, so that the valve piece 120 opens the second end 113 of the through hole 111, and the discharge passage is conducted to realize exhaust. When the compressor stops, the valve piece 120 closes the second end 113 of the through hole 111, and the discharge passage is cut off to avoid the situation that the compressor reverses due to the backflow of high-pressure air flow. In addition, when the compressor is in an under-compression working condition, by closing the second end 113 of the through hole 111 with the valve piece 120, it can effectively avoid the frequent backflow of high-pressure gas into the compression chamber, thereby causing the problem of repeated compression and improving the efficiency of the compressor.

[0107] At least one groove 114 is provided on one side surface of the valve plate 110 facing the valve piece 120. That is to say, at least one groove 114 is provided on the contact surface between the valve plate 110 and the valve piece 120, so as to effectively reduce the contact area between one side surface of the valve plate 110 facing the valve piece 120 and the valve piece 120, and significantly reduce the viscous force between the valve piece 120 and the surface of the valve plate 110 when the valve piece 120 opens the second end 113 of the through hole 111. Furthermore, it is beneficial to reduce the power consumption of the compressor and improve the energy efficiency of the compressor.

[0108] Moreover, it can be understood that during the exhaust process, there will be a certain amount of high-temperature and high-pressure gas in at least one groove 114. When the valve plate 120 closes the second end 113 of the through hole 111, it can generate a certain buffering force on the valve plate 120, thereby effectively slowing down the speed of the valve plate 120 hitting the surface of the valve plate 110, reducing the noise generated when the valve plate 120 closes the second end 113 of the through hole 111, and further being beneficial to reducing the noise of the whole compressor.

[0109] According to the third aspect of the present invention, a compressor is provided, which includes the exhaust valve assembly 100 or the static plate assembly 200 provided in any of the above embodiments, and thus has all the beneficial technical effects of the exhaust valve assembly 100 or the static plate assembly 200, which will not be elaborated here.

[0110] Optionally, from top to bottom, the compressor further includes an upper housing, a partition plate, a floating plate assembly, a stationary scroll (stationary scroll plate 210), a moving scroll (moving scroll plate), a main frame, a motor, a sub-frame, and a lower housing. Inside the compressor, with the partition plate as the boundary, the upper part is a high-pressure chamber, and the lower part is a low-pressure chamber. When the compressor works, the gaseous refrigerant enters the low-pressure chamber through the suction port on the housing, and after being compressed by the stationary and moving scrolls, it is discharged from the exhaust port 211 of the stationary scroll into the high-pressure chamber. When the compressor stops, an exhaust valve (exhaust valve assembly 100) needs to be provided at the exhaust port 211 of the static plate (stationary scroll plate 210) to prevent the refrigerant in the high-pressure chamber from flowing back, resulting in noise caused by the reverse rotation of the scroll.

[0111] According to the fourth aspect of the present invention, a refrigeration device is provided, which includes the exhaust valve assembly 100, the static plate assembly 200, or the compressor provided in any of the above embodiments, and thus has all the beneficial technical effects of the exhaust valve assembly 100, the static plate assembly 200, or the compressor, which will not be elaborated here.
