Description

Technical Field

[0001] The utility model relates to the technical field of compressor equipment, in particular to a stator assembly, a compressor and a refrigeration device. Background Art

[0002] Currently, scroll compressors typically incorporate a reed exhaust valve at the static scroll's exhaust port to prevent high-pressure backflow during shutdown, which can cause scroll reversal, and to prevent high-pressure gas from frequently backflowing into the pressure chamber and causing repeated compression during under-compression conditions. However, the reed valve disc experiences significant adhesion when opening the through-hole in the discharge valve plate, increasing compressor power consumption. Utility Model Content

[0003] The embodiments of the present utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the present invention provides a stator assembly.

[0005] A second aspect of the embodiments of the present invention provides a compressor.

[0006] A third aspect of the embodiments of the present invention provides a refrigeration device.

[0007] In view of this, according to the first aspect of an embodiment of the present utility model, a stator plate assembly is provided, the stator plate assembly comprising: a stator plate, the stator plate being provided with an exhaust port; an exhaust valve assembly connected to the stator plate, the exhaust valve assembly comprising a valve plate and a valve disc, the valve plate being located between the valve disc and the stator plate, the valve plate being provided with a through hole and a guide structure, the through hole being opposite to the exhaust port and being connected to the exhaust port, the valve disc being able to open or close the through hole, the first end of the guide structure being connected to the exhaust port, and the second end of the guide structure passing through the valve plate towards a side of the valve disc.

[0008] The stator plate assembly provided in the present invention includes a stator plate and an exhaust valve assembly. Specifically, the stator plate is provided with an exhaust port. Optionally, the compressor further includes a rotor plate, which, together with the stator plate, forms a compression chamber, which is connected to the exhaust port. Specifically, the rotor plate is capable of translational rotation relative to the stator plate to compress gas within the compression chamber. When the exhaust pressure is reached, the compressed, high-temperature, high-pressure gas is discharged through the exhaust port.

[0009] The exhaust valve assembly includes a valve plate and a valve disc. The valve plate is positioned between the valve plate and the stationary disc. The valve plate is provided with a through-hole that faces and communicates with the exhaust port. The valve disc can open or close the through-hole. Specifically, the lower end of the through-hole communicates with the exhaust port, and the valve disc can open or close the upper end of the through-hole to open or close the exhaust passage.

[0010] Specifically, when the compressor is running, the compressed high-temperature and high-pressure gas flows through the exhaust port and the through-hole in sequence, impacting the valve plate, so that the valve plate opens the through-hole, the discharge passage is connected, and exhaust is achieved. When the compressor is shut down, the valve plate closes the through-hole and the discharge passage is cut off to avoid the compressor reversal due to the backflow of high-pressure air. In addition, when the compressor is in an under-compression condition, the valve plate closes the through-hole, which can effectively prevent high-pressure gas from frequently backflowing into the compression chamber, thereby causing repeated compression problems, thereby improving the efficiency of the compressor.

[0011] The valve plate is also provided with a guide structure, the first end of the guide structure is connected to the exhaust port, and the second end of the guide structure passes through the valve plate toward a side of the valve plate. That is to say, when exhausting, in addition to impacting the valve plate through the through hole, the airflow can also flow out through the guide structure and impact the valve plate, thereby significantly increasing the force area at the bottom of the valve plate and reducing the pressure difference required to open the valve plate. Moreover, it effectively reduces the adhesion area of ​​the oil film on the valve plate, thereby reducing the adhesion force of the oil film, making the valve plate easier to open, and realizing rapid response of the valve plate, which is beneficial to reducing the power consumption of the compressor and improving the overall performance and efficiency of the compressor.

[0012] Moreover, it is understandable that during the exhaust process, a certain amount of high-pressure gas will be contained in the guide structure, which can produce a certain buffering force on the valve plate when the valve plate closes the through hole, thereby effectively slowing down the speed at which the valve plate hits the surface of the valve plate, reducing the noise generated when the valve plate closes the through hole, and improving the reliability of the valve plate.

[0013] In addition, the static disk assembly provided by the above technical solution of the utility model also has the following additional technical features:

[0014] In some technical solutions, optionally, the guide structure includes a first guide groove and a guide hole, wherein the first guide groove is arranged on a side of the valve plate facing away from the valve plate and is connected to the exhaust port, and the guide hole is connected to the first guide groove, and along the axial direction of the static disk, the guide hole passes through the two opposite sides of the valve plate.

[0015] In this technical solution, the guide structure is defined to include a first guide groove and a guide hole. Specifically, the first guide groove is arranged on a side of the valve plate away from the valve sheet, that is, the bottom surface of the valve plate is provided with a first guide groove, and the first guide groove is connected to the exhaust port.

[0016] The guide holes extend axially along the stator plate through opposite sides of the valve plate. Specifically, the two ends of the guide holes extend through the top and bottom surfaces of the valve plate, and the guide holes are connected to the first guide grooves. Specifically, during exhaust, in addition to impacting the valve plate through the through holes, the airflow can also flow out through the first guide grooves and guide holes, impacting the valve plate. This significantly increases the pressure-sensitive surface area at the bottom of the valve plate and effectively reduces the oil film adhesion area, thereby reducing the oil film adhesion force. This allows for a faster opening response when the valve plate is subjected to gas forces, improving the overall performance and efficiency of the compressor.

[0017] Moreover, it is understandable that during the exhaust process, a certain amount of high-pressure gas will be contained in the guide hole, which can produce a certain buffering force on the valve plate when the valve plate closes the through hole, thereby effectively slowing down the speed at which the valve plate hits the surface of the valve plate, reducing the noise generated when the valve plate closes the through hole, and improving the reliability of the valve plate.

[0018] In some technical solutions, optionally, the first guide groove is located between the through hole and the guide hole.

[0019] In this technical solution, the first guide groove is defined as being located between the through hole and the guide hole. Since the guide hole is a through hole, that is, part of the valve plate is left between the through hole and the through hole, and the through holes and the through holes are not directly connected. Therefore, when the valve plate closes the through hole, the concave deformation of the valve plate can be effectively reduced, thereby reducing the local stress of the valve plate, which is beneficial to extending the service life of the valve plate and further improving the reliability of the valve plate.

[0020] In some technical solutions, optionally, there are multiple guide holes, and at least one guide hole is connected to the first guide groove.

[0021] In this technical solution, the number of guide holes is limited to multiple. Specifically, at least one guide hole is connected to the first guide groove. That is to say, when exhausting, in addition to impacting the valve plate through the through hole, the airflow can also flow out through the first guide groove and multiple guide holes and impact the valve plate, thereby further increasing the pressure action area at the bottom of the valve plate and further reducing the oil film adhesion area, so that the valve plate can be quickly opened when it is subjected to the force of the gas.

[0022] Moreover, when the valve plate closes the through hole, the setting of multiple guide holes can increase the buffering force on the valve plate, thereby effectively slowing down the speed at which the valve plate hits the valve plate surface, reducing the noise generated when the valve plate closes the through hole, and improving the reliability of the valve plate.

[0023] In some technical solutions, optionally, the flow area of ​​the end of the guide hole facing away from the valve plate is smaller than the flow area of ​​the end of the guide hole facing the valve plate.

[0024] In this technical solution, the flow area of ​​the end of the guide hole facing away from the valve plate is limited to be smaller than the flow area of ​​the end of the guide hole facing the valve plate, that is, the flow area of ​​the lower end of the guide hole is smaller than the flow area of ​​the upper end. Therefore, when exhausting, the flow resistance of the airflow in the guide structure can be reduced, so that the airflow can quickly impact the valve plate through the guide structure, thereby reducing the pressure difference required to open the valve plate.

[0025] Optionally, the guide hole includes a stepped hole.

[0026] Optionally, the shape of the guide hole can be set according to actual needs. Wherein, the guide hole includes a special-shaped hole.

[0027] In some technical solutions, optionally, one end of the first guide groove is connected to the through hole, and the other end of the first guide groove extends obliquely toward the side where the guide hole is located.

[0028] In this technical solution, one end of the first guide groove is connected to the through hole, that is, the first guide groove is connected to the exhaust port through the through hole, so that the airflow is guided to the guide hole through the through hole and the first guide groove during exhaust, thereby increasing the force area at the bottom of the valve plate, reducing the adhesion of the oil film, and realizing rapid response of the valve plate.

[0029] Since the other end of the first guide groove extends obliquely toward the side where the guide hole is located, that is, the groove wall of the first guide groove is an inclined surface, it can guide the airflow, so that the airflow can flow quickly to the guide hole through the through hole and the first guide groove, which is beneficial to further improve the response speed of the valve plate.

[0030] In some technical solutions, optionally, the stator plate assembly further includes a second guide groove, which is provided on the side of the stator plate facing the valve plate and is connected to the exhaust port, and the second guide groove is connected to at least one of the first guide groove and the guide hole.

[0031] This technical solution specifies that the stator plate assembly also includes a second guide groove. Specifically, the second guide groove is disposed on the side of the stator plate facing the valve plate and is connected to the exhaust port. Specifically, the second guide groove is connected to the first guide groove. Alternatively, the second guide groove is connected to the guide hole. Alternatively, both the first guide groove and the guide hole are connected to the second guide groove. The specific configuration can be determined based on actual needs.

[0032] By opening a second guide groove on the stator, the flow area of ​​the airflow from the exhaust port to the guide structure can be significantly increased, so that the airflow can be quickly guided to the guide structure, which can further increase the impact force on the valve plate during exhaust, reduce the pressure difference required to open the valve plate, achieve a rapid response to the valve plate opening, reduce the power consumption of the compressor, and improve the performance of the compressor.

[0033] In some technical solutions, optionally, one end of the second guide groove is connected to the exhaust port, the other end of the second guide groove extends radially along the stator disk, and at least a portion of the guide hole is opposite to the second guide groove.

[0034] In this technical solution, one end of the second guide groove is connected to the exhaust port, and the other end extends radially to be opposite to the guide hole. That is to say, the first guide groove and the guide hole are both connected to the second guide groove, thereby further increasing the flow area of ​​the airflow from the exhaust port to the guide structure, so that the airflow can be quickly guided to the guide hole, which can further increase the impact force on the valve plate during exhaust, reduce the pressure difference required to open the valve plate, achieve rapid response of the valve plate opening, reduce the power consumption of the compressor, and improve the performance of the compressor.

[0035] In some technical solutions, optionally, the cross-sectional area of ​​the second guide groove is greater than or equal to the cross-sectional area of ​​the guide structure.

[0036] In this technical solution, the cross-sectional area of ​​the second guide groove is limited to be greater than or equal to the cross-sectional area of ​​the guide structure, thereby further increasing the flow area of ​​the airflow from the exhaust port to the guide structure, so that the airflow can be quickly guided to the guide structure, further increasing the impact force on the valve plate during exhaust, reducing the pressure difference required for the valve plate to open, and achieving a rapid response of the valve plate to open.

[0037] In some technical solutions, optionally, the width of the second guide groove is smaller than the width of the valve plate.

[0038] In this technical solution, the width of the second guide groove is limited to be smaller than the width of the valve plate, thereby increasing the flow area of ​​the airflow from the exhaust port to the guide structure, allowing the airflow to be quickly guided to the guide structure while avoiding airflow leakage from other positions, thereby ensuring the energy efficiency of the compressor.

[0039] In some technical solutions, optionally, the guide structure and the through hole are spaced apart.

[0040] In this technical solution, the guide structure and the through hole are set at intervals, that is, another drainage method is defined. Specifically, the guide structure is connected to the second guide groove but not to the through hole. That is, when exhausting, the air flow flowing out of the exhaust port flows to the guide structure through the second guide groove to increase the force area at the bottom of the valve plate and reduce the adhesion of the oil film, so that the valve plate is easier to open, which is beneficial to reducing the power consumption of the compressor and improving the overall performance and efficiency of the compressor.

[0041] In some technical solutions, optionally, the valve plate includes a valve head, a connecting portion and a fixed portion, the valve head is provided with a through hole, any one of the static disk and the valve plate is connected to the connecting portion, the fixed portion is located between the valve head and the connecting portion, both ends of the fixed portion are respectively connected to the valve head and the connecting portion, and the guide structure is provided on the fixed portion; wherein the length a of the guide structure and the length b of the fixed portion satisfy

[0042] This technical solution defines a valve plate comprising a valve head, a connecting portion, and a fixed portion. Specifically, the valve head is provided with a through hole, and the connecting portion is connected to the stationary disc and valve plate. The fixed portion is located between the valve head and the connecting portion, and the flow guide structure is provided on the fixed portion. In other words, the flow guide structure is located at the waist of the valve plate.

[0043] Since the length of the guide structure is greater than or equal to two-thirds of the length of the fixed part, that is, the guide structure extends to a position close to the connecting part, that is, the guide structure extends to the area close to the root of the valve plate. Specifically, when exhausting, the guide structure guides the airflow flowing out of the exhaust port to the waist of the valve plate and the area close to the root, and directly applies gas pressure to the root and waist areas of the valve plate, thereby increasing the force area at the bottom of the valve plate, making the valve plate open quickly, and improving the response speed of the valve plate.

[0044] In some technical solutions, optionally, the stator assembly further includes support ribs, which are provided at the through hole and connected to the valve plate. The support ribs divide the through hole into at least a first sub-hole and a second sub-hole, and the first sub-hole and the second sub-hole are respectively connected to the exhaust port.

[0045] In this technical solution, it is defined that the static disc assembly also includes support ribs. Specifically, the support ribs are arranged in the through hole, that is, a support structure is formed in the through hole, so that when the valve plate closes the through hole, the 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, extending the service life of the valve plate, and improving the reliability of the valve plate.

[0046] Moreover, since the support ribs divide the through hole into at least a first sub-hole and a second sub-hole, and the first sub-hole and the second sub-hole are respectively connected to the exhaust port, when the valve plate opens the through hole for exhaust, it can disperse the high-pressure airflow, effectively reduce the torsional deformation and flutter of the valve plate, and further improve the reliability of the valve plate.

[0047] Optionally, there are multiple support ribs, and the multiple support ribs divide the through hole into multiple sub-holes. It can be understood that by reasonably designing the size and position of the multiple sub-holes, the size of the impact force of the airflow on the valve plate and the position of the airflow on the valve plate can be adjusted.

[0048] In some technical solutions, optionally, the exhaust valve assembly further includes a limiter, which is located on a side of the valve disc facing away from the valve plate and is connected to the valve disc, the valve plate and the static disk.

[0049] In this technical solution, it is defined that the exhaust valve assembly further includes a limiter. Specifically, the limiter is arranged on the side of the valve disc facing away from the valve plate, that is, the valve disc is located between the valve plate and the limiter.

[0050] By setting a limiter, the valve plate can be limited when the valve plate opens the through hole, avoiding the problem of the valve plate being damaged due to excessive deformation under the impact of high-temperature and high-pressure gas, ensuring that the valve plate can effectively close the through hole, avoiding gas backflow or re-injection, which is beneficial to extending the service life of the valve plate.

[0051] Optionally, connecting holes are respectively provided on the connecting part of the valve plate, one end of the valve disc, one end of the limiter and the stator, and the compressor also includes screws, which pass through the connecting holes on the limiter, the connecting holes on the valve disc, the connecting holes on the connecting part and the connecting holes on the stator in sequence, thereby fixing the limiter, the valve disc and the valve plate to the stator.

[0052] According to a second aspect of the present invention, a compressor is provided, comprising a stator assembly as provided by any of the above technical solutions, thereby possessing all the beneficial technical effects of the stator assembly, which will not be described in detail here.

[0053] According to a third aspect of the present invention, a refrigeration device is provided, comprising a stator assembly or a compressor as provided by any of the above technical solutions, thereby having all the beneficial technical effects of the stator assembly or the compressor, which will not be repeated here.

DETAILED DESCRIPTION

[0061] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0062] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0063] Refer to the following Figures 1 to 3 The stator plate assembly 100, the compressor and the refrigeration equipment according to some embodiments of the present invention are described.

[0064] In one embodiment according to the present application, Figure 1 and Figure 2 As shown, a stator plate assembly 100 is proposed, which includes: a stator plate 110, which is provided with an exhaust port 111; an exhaust valve assembly 120, which is connected to the stator plate 110, and the exhaust valve assembly 120 includes a valve plate 121 and a valve disc 122, the valve plate 121 is located between the valve disc 122 and the stator plate 110, the valve plate 121 is provided with a through hole 123 and a guide structure 124, the through hole 123 is opposite to the exhaust port 111 and is connected to the exhaust port 111, the valve disc 122 can open or close the through hole 123, the first end of the guide structure 124 is connected to the exhaust port 111, and the second end of the guide structure 124 passes through the valve plate 121 toward a side of the valve disc 122.

[0065] The stator plate assembly 100 provided in this embodiment of the present invention includes a stator plate 110 and an exhaust valve assembly 120. Specifically, the stator plate 110 is provided with an exhaust port 111. Optionally, the compressor further includes a rotor plate, which, together with the stator plate 110, forms a compression chamber, which is communicated with the exhaust port 111. Specifically, the rotor plate can rotate translationally relative to the stator plate 110 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 111.

[0066] The exhaust valve assembly 120 includes a valve plate 121 and a valve disc 122. Valve plate 121 is positioned between valve disc 122 and stator plate 110. Valve plate 121 is provided with a through hole 123, which is opposite and communicates with exhaust port 111. Valve disc 122 can open or close through hole 123. Specifically, the lower end of through hole 123 communicates with exhaust port 111, and valve disc 122 can open or close the upper end of through hole 123 to open or close the exhaust passage.

[0067] Specifically, when the compressor is running, the compressed high-temperature and high-pressure gas flows through the exhaust port 111 and the through hole 123 in sequence, impacting the valve plate 122, so that the valve plate 122 opens the through hole 123, the discharge passage is connected, and exhaust is achieved. When the compressor is shut down, the valve plate 122 closes the through hole 123 and the discharge passage is cut off to avoid the compressor reversal due to the backflow of high-pressure air. In addition, when the compressor is in an under-compression condition, the valve plate 122 closes the through hole 123, which can effectively prevent the high-pressure gas from frequently returning to the compression chamber, thereby causing the problem of repeated compression, thereby improving the efficiency of the compressor.

[0068] The valve plate 121 is also provided with a guide structure 124, a first end of the guide structure 124 is connected to the exhaust port 111, and the second end of the guide structure 124 passes through the side of the valve plate 121 facing the valve plate 122. That is to say, when exhausting, in addition to impacting the valve plate 122 through the through hole 123, the airflow can also flow out through the guide structure 124 and impact the valve plate 122, thereby significantly increasing the force-bearing area at the bottom of the valve plate 122 and reducing the pressure difference required to open the valve plate 122. Moreover, it effectively reduces the adhesion area of ​​the oil film on the valve plate 122, thereby reducing the adhesion force of the oil film, making the valve plate 122 easier to open, and realizing the rapid response of the valve plate 122, which is beneficial to reducing the power consumption of the compressor and improving the overall performance and efficiency of the compressor.

[0069] Moreover, it is understandable that during the exhaust process, the guide structure 124 will contain a certain amount of high-pressure gas, which can generate a certain buffering force on the valve plate 122 when the valve plate 122 closes the through hole 123, thereby effectively slowing down the speed at which the valve plate 122 hits the surface of the valve plate 121, reducing the noise generated when the valve plate 122 closes the through hole 123, and improving the reliability of the valve plate 122.

[0070] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the guide structure 124 includes a first guide groove 125 and a guide hole 126, wherein the first guide groove 125 is provided on a side of the valve plate 121 away from the valve plate 122 and is connected to the exhaust port 111, and the guide hole 126 is connected to the first guide groove 125, and along the axial direction of the stator plate 110, the guide hole 126 passes through the two opposite sides of the valve plate 121.

[0071] In this embodiment, the guide structure 124 is defined to include a first guide groove 125 and a guide hole 126. Specifically, the first guide groove 125 is arranged on a side of the valve plate 121 away from the valve sheet 122, that is, the bottom surface of the valve plate 121 is provided with the first guide groove 125, and the first guide groove 125 is connected to the exhaust port 111.

[0072] The guide holes 126 extend axially through two opposite side surfaces of the valve plate 121 along the stator plate 110. That is, both ends of the guide holes 126 extend through the top and bottom surfaces of the valve plate 121, and the guide holes 126 communicate with the first guide grooves 125. Specifically, during exhaust, in addition to impacting the valve plate 122 through the through holes 123, the airflow can also flow out through the first guide grooves 125 and the guide holes 126 and impact the valve plate 122. This significantly increases the pressure-applied area at the bottom of the valve plate 122, effectively reduces the oil film adhesion area, and thus reduces the oil film adhesion force. This allows for a faster opening response when the valve plate 122 is subjected to the force of gas, thereby improving the overall performance and efficiency of the compressor.

[0073] Moreover, it is understandable that during the exhaust process, a certain amount of high-pressure gas will be contained in the guide hole 126, which can generate a certain buffering force on the valve plate 122 when the valve plate 122 closes the through hole 123, thereby effectively slowing down the speed at which the valve plate 122 hits the surface of the valve plate 121, reducing the noise generated when the valve plate 122 closes the through hole 123, and improving the reliability of the valve plate 122.

[0074] like Figure 2 As shown, in some embodiments, optionally, the first guide groove 125 is located between the through hole 123 and the guide hole 126 .

[0075] In this embodiment, the first guide groove 125 is defined as being located between the through hole 123 and the guide hole 126. Since the guide hole 126 is a through hole 123, that is, part of the valve plate 121 is left between the through holes 123 and the through holes 123, and the through holes 123 and the through holes 123 are not directly connected. Therefore, when the valve plate 122 closes the through hole 123, the concave deformation of the valve plate 122 can be effectively reduced, thereby reducing the local stress of the valve plate 122, which is beneficial to extending the service life of the valve plate 122 and further improving the reliability of the valve plate 122.

[0076] In some embodiments, optionally, there are multiple guide holes 126 , and at least one guide hole 126 is connected to the first guide groove 125 .

[0077] In this embodiment, the number of guide holes 126 is limited to multiple. Specifically, at least one guide hole 126 is connected to the first guide groove 125. That is to say, when exhausting, in addition to impacting the valve plate 122 through the through hole 123, the airflow can also flow out through the first guide groove 125 and multiple guide holes 126 and impact the valve plate 122, thereby further increasing the pressure action area at the bottom of the valve plate 122 and further reducing the oil film adhesion area, so that the valve plate 122 can be quickly opened when it is subjected to the force of the gas.

[0078] Moreover, when the valve plate 122 closes the through hole 123, the setting of multiple guide holes 126 can increase the buffering force on the valve plate 122, thereby effectively slowing down the speed at which the valve plate 122 hits the surface of the valve plate 121, reducing the noise generated when the valve plate 122 closes the through hole 123, and improving the reliability of the valve plate 122.

[0079] In some embodiments, optionally, the flow area of ​​the end of the guide hole 126 facing away from the valve plate 122 is smaller than the flow area of ​​the end of the guide hole 126 facing the valve plate 122 .

[0080] In this embodiment, the flow area of ​​the end of the guide hole 126 facing away from the valve plate 122 is limited to be smaller than the flow area of ​​the end of the guide hole 126 facing the valve plate 122, that is, the flow area of ​​the lower end of the guide hole 126 is smaller than the flow area of ​​the upper end. Therefore, when exhausting, the flow resistance of the airflow in the guide structure 124 can be reduced, so that the airflow can quickly impact the valve plate 122 through the guide structure 124, thereby reducing the pressure difference required to open the valve plate 122.

[0081] Optionally, the guide hole 126 includes a stepped hole.

[0082] Optionally, the shape of the guide hole 126 can be set according to actual needs. Wherein, the guide hole 126 includes a special-shaped hole.

[0083] In some embodiments, optionally, one end of the first guide groove 125 is communicated with the through hole 123 , and the other end of the first guide groove 125 extends obliquely toward the side where the guide hole 126 is located.

[0084] In this embodiment, one end of the first guide groove 125 is defined to be connected to the through hole 123, that is, the first guide groove 125 is connected to the exhaust port 111 through the through hole 123, so that the airflow is guided to the guide hole 126 through the through hole 123 and the first guide groove 125 during exhaust, thereby increasing the force-bearing area at the bottom of the valve plate 122, reducing the adhesion of the oil film, and achieving a rapid response of the valve plate 122.

[0085] Since the other end of the first guide groove 125 extends obliquely toward the side where the guide hole 126 is located, that is, the groove wall of the first guide groove 125 is an inclined surface, it can guide the airflow, so that the airflow can flow quickly to the guide hole 126 through the through hole 123 and the first guide groove 125, which is beneficial to further improve the response speed of the valve plate 122.

[0086] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the stator plate assembly 100 further includes a second guide groove 130 , which is provided on the side of the stator plate 110 facing the valve plate 121 and is connected to the exhaust port 111 , and the second guide groove 130 is connected to at least one of the first guide groove 125 and the guide hole 126 .

[0087] In this embodiment, the stator plate assembly 100 further includes a second guide groove 130. Specifically, the second guide groove 130 is disposed on the side of the stator plate 110 facing the valve plate 121 and is in communication with the exhaust port 111. Specifically, the second guide groove 130 is in communication with the first guide groove 125. Alternatively, the second guide groove 130 is in communication with the guide hole 126. Alternatively, both the first guide groove 125 and the guide hole 126 are in communication with the second guide groove 130. The specific configuration can be determined based on actual needs.

[0088] By opening a second guide groove 130 on the stator plate 110, the flow area of ​​the airflow from the exhaust port 111 to the guide structure 124 can be significantly increased, so that the airflow can be quickly guided to the guide structure 124, which can further increase the impact force on the valve plate 122 during exhaust, reduce the pressure difference required to open the valve plate 122, achieve a rapid response to the opening of the valve plate 122, reduce the power consumption of the compressor, and improve the performance of the compressor.

[0089] like Figure 1 As shown, in some embodiments, optionally, one end of the second guide groove 130 is connected to the exhaust port 111 , and the other end of the second guide groove 130 extends radially along the stator plate 110 , and at least a portion of the guide hole 126 is opposite to the second guide groove 130 .

[0090] In this embodiment, one end of the second guide groove 130 is connected to the exhaust port 111, and the other end extends radially to be opposite to the guide hole 126. That is to say, the first guide groove 125 and the guide hole 126 are both connected to the second guide groove 130, thereby further increasing the flow area of ​​the airflow from the exhaust port 111 to the guide structure 124, so that the airflow can be quickly guided to the guide hole 126, which can further increase the impact force on the valve plate 122 during exhaust, reduce the pressure difference required to open the valve plate 122, achieve a rapid response to the opening of the valve plate 122, reduce the power consumption of the compressor, and improve the performance of the compressor.

[0091] In some embodiments, optionally, the cross-sectional area of ​​the second guide groove 130 is greater than or equal to the cross-sectional area of ​​the guide structure 124 .

[0092] In this embodiment, the cross-sectional area of ​​the second guide groove 130 is limited to be greater than or equal to the cross-sectional area of ​​the guide structure 124, thereby further increasing the flow area of ​​the airflow from the exhaust port 111 to the guide structure 124, so that the airflow can be quickly guided to the guide structure 124, further increasing the impact force on the valve plate 122 during exhaust, reducing the pressure difference required to open the valve plate 122, and achieving a rapid response of the valve plate 122 to open.

[0093] In some embodiments, optionally, the width of the second guide groove 130 is smaller than the width of the valve plate 121 .

[0094] In this embodiment, the width of the second guide groove 130 is limited to be smaller than the width of the valve plate 121, thereby increasing the flow area of ​​the airflow from the exhaust port 111 to the guide structure 124, allowing the airflow to be quickly guided to the guide structure 124 while avoiding leakage of the airflow from other positions, thereby ensuring the energy efficiency of the compressor.

[0095] In some embodiments, optionally, the guide structure 124 is spaced apart from the through hole 123 .

[0096] In this embodiment, the guide structure 124 is defined to be spaced apart from the through hole 123, that is, another drainage method is defined. Specifically, the guide structure 124 is connected to the second guide groove 130, but not to the through hole 123. That is, when exhausting, the airflow flowing out of the exhaust port 111 flows to the guide structure 124 through the second guide groove 130, so as to increase the force-bearing area at the bottom of the valve plate 122 and reduce the adhesion of the oil film, thereby making the valve plate 122 easier to open, which is beneficial to reducing the power consumption of the compressor and improving the overall performance and efficiency of the compressor.

[0097] like Figure 2 As shown, in some embodiments, optionally, the valve plate 121 includes a valve head 160, a connecting portion 127 and a fixing portion 170, the valve head 160 is provided with a through hole 123, any one of the static plate 110 and the valve plate 122 is connected to the connecting portion 127, the fixing portion 170 is located between the valve head 160 and the connecting portion 127, the two ends of the fixing portion 170 are respectively connected to the valve head 160 and the connecting portion 127, and the guide structure 124 is provided on the fixing portion 170; wherein, the length a of the guide structure 124 and the length b of the fixing portion 170 meet

[0098] In this embodiment, the valve plate 121 is defined as comprising a valve head 160, a connecting portion 127, and a fixing portion 170. Specifically, the valve head 160 is provided with a through hole 123, and the connecting portion 127 is connected to the stator plate 110 and the valve plate 122. The fixing portion 170 is located between the valve head 160 and the connecting portion 127, and the flow guide structure 124 is disposed on the fixing portion 170. In other words, the flow guide structure 124 is located at the waist of the valve plate 121.

[0099] Since the length of the guide structure 124 is greater than or equal to two-thirds of the length of the fixed portion 170, that is, the guide structure 124 extends to a position close to the connecting portion 127, that is, the guide structure 124 extends to the area close to the root of the valve plate 121. Specifically, when exhausting, the guide structure 124 guides the airflow flowing out of the exhaust port 111 to the waist and the area close to the root of the valve plate 121, and directly applies gas pressure to the root and waist areas of the valve plate 122, thereby increasing the force area at the bottom of the valve plate 122, so that the valve plate 122 opens quickly, and the response speed of the valve plate 122 is improved.

[0100] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the stator plate assembly 100 further includes a support rib 140, which is disposed at the through hole 123 and connected to the valve plate 121. The support rib 140 divides the through hole 123 into at least a first sub-hole 128 and a second sub-hole 129, and the first sub-hole 128 and the second sub-hole 129 are respectively connected to the exhaust port 111.

[0101] In this embodiment, it is defined that the stator plate assembly 100 also includes support ribs 140. Specifically, the support ribs 140 are arranged in the through hole 123, that is, a support structure is formed in the through hole 123, so that when the valve plate 122 closes the through hole 123, the concave deformation of the valve plate 122 at the position of the through hole 123 can be effectively reduced, which is beneficial to reducing the local stress of the valve plate 122, extending the service life of the valve plate 122, and improving the reliability of the valve plate 122.

[0102] Moreover, since the support rib 140 divides the through hole 123 into at least the first sub-hole 128 and the second sub-hole 129, and the first sub-hole 128 and the second sub-hole 129 are respectively connected to the exhaust port 111, when the valve plate 122 opens the through hole 123 for exhaust, it can disperse the high-pressure airflow, effectively reduce the torsional deformation and flutter of the valve plate 122, and further improve the reliability of the valve plate 122.

[0103] Optionally, there are multiple support ribs 140, and multiple support ribs 140 divide the through hole 123 into multiple sub-holes. It can be understood that by reasonably designing the size and position of the multiple sub-holes, the size of the impact force of the airflow acting on the valve plate 122 and the position of the airflow acting on the valve plate 122 can be adjusted.

[0104] like Figure 1 As shown, in some embodiments, optionally, the exhaust valve assembly 120 further includes a stopper 150 , which is located on a side of the valve disc 122 facing away from the valve plate 121 and is connected to the valve disc 122 , the valve plate 121 and the static plate 110 .

[0105] In this embodiment, the exhaust valve assembly 120 further includes a stopper 150 . Specifically, the stopper 150 is disposed on a side of the valve disc 122 facing away from the valve plate 121 . That is, the valve disc 122 is located between the valve plate 121 and the stopper 150 .

[0106] By setting the limiter 150, the valve plate 122 can be limited when the valve plate 122 opens the through hole 123, thereby avoiding the problem that the valve plate 122 is damaged due to excessive deformation under the impact of high-temperature and high-pressure gas, ensuring that the valve plate 122 can effectively close the through hole 123, avoiding gas backflow or re-injection, which is beneficial to extending the service life of the valve plate 122.

[0107] Optionally, connecting holes are respectively provided on the connecting portion 127 of the valve plate 121, one end of the valve disc 122, one end of the limiter 150 and the stator 110, and the compressor also includes screws, which pass through the connecting holes on the limiter 150, the connecting holes on the valve disc 122, the connecting holes on the connecting portion 127 and the connecting holes on the stator 110 in sequence, thereby fixing the limiter 150, the valve disc 122 and the valve plate 121 to the stator 110.

[0108] According to a second aspect of the present invention, a compressor is provided, comprising a stator plate assembly 100 as provided in any of the above embodiments, thereby possessing all the beneficial technical effects of the stator plate assembly 100, which will not be described in detail herein.

[0109] Specifically, the stator plate assembly 100 includes a stator plate 110 and an exhaust valve assembly 120. Specifically, the stator plate 110 is provided with an exhaust port 111. Optionally, the compressor further includes a rotor plate, which, together with the stator plate 110, forms a compression chamber, which is connected to the exhaust port 111. Specifically, the rotor plate can rotate translationally relative to the stator plate 110 to compress the gas in the compression chamber. When the exhaust pressure is reached, the compressed, high-temperature, high-pressure gas is discharged from the exhaust port 111.

[0110] The exhaust valve assembly 120 includes a valve plate 121 and a valve disc 122. Valve plate 121 is positioned between valve disc 122 and stator plate 110. Valve plate 121 is provided with a through hole 123, which is opposite and communicates with exhaust port 111. Valve disc 122 can open or close through hole 123. Specifically, the lower end of through hole 123 communicates with exhaust port 111, and valve disc 122 can open or close the upper end of through hole 123 to open or close the exhaust passage.

[0111] Specifically, when the compressor is running, the compressed high-temperature and high-pressure gas flows through the exhaust port 111 and the through hole 123 in sequence, impacting the valve plate 122, so that the valve plate 122 opens the through hole 123, the discharge passage is connected, and exhaust is achieved. When the compressor is shut down, the valve plate 122 closes the through hole 123 and the discharge passage is cut off to avoid the compressor reversal due to the backflow of high-pressure air. In addition, when the compressor is in an under-compression condition, the valve plate 122 closes the through hole 123, which can effectively prevent the high-pressure gas from frequently returning to the compression chamber, thereby causing the problem of repeated compression, thereby improving the efficiency of the compressor.

[0112] The valve plate 121 is also provided with a guide structure 124, a first end of the guide structure 124 is connected to the exhaust port 111, and the second end of the guide structure 124 passes through the side of the valve plate 121 facing the valve plate 122. That is to say, when exhausting, in addition to impacting the valve plate 122 through the through hole 123, the airflow can also flow out through the guide structure 124 and impact the valve plate 122, thereby significantly increasing the force-bearing area at the bottom of the valve plate 122 and reducing the pressure difference required to open the valve plate 122. Moreover, it effectively reduces the adhesion area of ​​the oil film on the valve plate 122, thereby reducing the adhesion force of the oil film, making the valve plate 122 easier to open, and realizing the rapid response of the valve plate 122, which is beneficial to reducing the power consumption of the compressor and improving the overall performance and efficiency of the compressor.

[0113] Moreover, it is understandable that during the exhaust process, the guide structure 124 will contain a certain amount of high-pressure gas, which can generate a certain buffering force on the valve plate 122 when the valve plate 122 closes the through hole 123, thereby effectively slowing down the speed at which the valve plate 122 hits the surface of the valve plate 121, reducing the noise generated when the valve plate 122 closes the through hole 123, and improving the reliability of the valve plate 122.

[0114] According to a third aspect of the present invention, a refrigeration device is provided, comprising a stator assembly 100 or a compressor as provided in any of the above embodiments, thereby having all the beneficial technical effects of the stator assembly 100 or the compressor, which will not be described in detail here.
