Description

Technical Field

[0001] This utility model relates to the field of compressor equipment technology, and more specifically, to a static disk structure, a compressor, and a refrigeration device. Background Technology

[0002] Currently, scroll compressors in related technologies generally use a motor to drive a scroll plate to form a fan-shaped cavity to compress the refrigerant and exchange heat with other media to achieve cooling or heating effects. However, in scroll compressors of related technologies, the high-temperature and high-pressure gas generated after compression by the scroll plate experiences high-frequency valve plate slapping when passing through the stationary plate exhaust port, resulting in high-frequency noise at the exhaust port. Utility Model Content

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

[0004] Therefore, a first aspect of the embodiments of this utility model provides a static disk structure.

[0005] A second aspect of the embodiments of this utility model provides a compressor.

[0006] A third aspect of the embodiments of this utility model provides a refrigeration device.

[0007] In view of the above, according to a first aspect of the present invention, a stationary disc structure is provided, comprising: a disc body, the disc body having an exhaust hole, a guide groove, an exhaust channel, and a movable cavity, the guide groove being located between the exhaust hole and the movable cavity along the radial direction of the disc body, the exhaust channel being located outside the movable cavity, one end of the exhaust channel communicating with the guide groove, and the other end of the exhaust channel penetrating the disc body; a check valve, movably disposed within the movable cavity, for opening or sealing the exhaust hole; and a limiting component connected to the disc body and located on the side of the check valve away from the exhaust hole; wherein, based on the check valve opening the exhaust hole, the exhaust hole communicates with the guide groove, and the check valve can abut against the limiting component; based on the check valve sealing the exhaust hole, the exhaust hole is cut off from the guide groove.

[0008] The stationary disc structure provided in this embodiment includes a disc body, a check valve, and a limiting component. Specifically, the disc body is provided with an exhaust port. Optionally, the disc body and the moving disc form a compression chamber, which is connected to the exhaust port. Specifically, during the operation of the compressor, the moving disc rotates relative to the disc body to compress the gas in the compression chamber. When the gas pressure in the compression chamber reaches the exhaust pressure, the compressed high-temperature and high-pressure gas is discharged from the exhaust port to the exhaust chamber, and finally discharged from the exhaust chamber to the outside of the compressor housing.

[0009] The check valve can move within the movable chamber to open or close the exhaust port. Specifically, when the compressor discharges, the high-pressure gas impacts the check valve, causing it to move away from the exhaust port to open it. The high-pressure gas is then discharged through the exhaust port, the guide groove, and the exhaust passage.

[0010] When the compressor operates under under-compression conditions or when it stops, the high-pressure gas flows back, impacting the check valve and moving it towards the side closer to the exhaust port to seal it. This shuts off the exhaust port and the guide channel, preventing high-pressure gas from flowing back into the compression chamber from the exhaust port. This effectively solves the problem of high compressor noise caused by high-pressure gas backflow when the compressor is operating under under-compression conditions, and also prevents the compressor from reversing due to high-pressure gas backflow when it stops. This reduces the high and low pressure balancing time and improves the reliability of the compressor.

[0011] Because a limiting component is installed on the side of the check valve away from the exhaust port, when the compressor discharges gas, the high-pressure gas impacts the check valve, causing it to move away from the exhaust port. When the exhaust port is opened, the check valve can abut against the limiting component, thus limiting its movement within the moving chamber. This prevents the check valve from coming off and avoids jamming or wear during the upward or downward movement caused by the high-pressure gas impact. This ensures that the check valve can smoothly fall back to cover the exhaust port when the compressor is operating under under-compression conditions or when it stops. Furthermore, during installation, the check valve can be placed in the moving chamber first, and then the limiting component can be installed. This solves the problem of the check valve easily falling off during installation, reducing the difficulty of compressor installation and improving assembly efficiency.

[0012] In addition, since the disc body is equipped with an exhaust channel and a guide groove, and the exhaust channel is located on the radial outer side of the moving cavity, when the compressor exhausts, the high-pressure gas flowing out from the exhaust hole impacts the check valve, causing the exhaust hole to open. At the same time, the high-pressure gas flows out through the guide groove and the exhaust channel. In other words, the high-pressure gas flowing out from the exhaust hole is diverted, which can effectively reduce the high-frequency knocking sound of the check valve. At the same time, it can also reduce the direct impact of the high-pressure airflow on the top parts of the compressor, thereby significantly reducing the overall operating noise of the compressor.

[0013] In some technical solutions, optionally, there are multiple exhaust channels, which are arranged circumferentially along the disc body and are connected to the guide grooves respectively.

[0014] In this technical solution, the number of exhaust channels is limited to multiple. Specifically, multiple exhaust channels are arranged along the circumference of the disc body, and each of the multiple exhaust channels is connected to the guide groove.

[0015] Specifically, when the compressor discharges, the high-pressure gas flowing out of the discharge port impacts the check valve, causing the discharge port to open. At the same time, the high-pressure gas flows out through the guide groove and multiple discharge channels, which diverts the high-pressure gas flowing out of the discharge port. This reduces the high-frequency knocking sound of the check valve, slows down the direct impact of the high-pressure airflow on the top parts of the compressor, and thus reduces the overall operating noise of the compressor while ensuring the discharge efficiency of the compressor to meet the cooling or heating requirements.

[0016] Optionally, the cross-sectional shape of the exhaust channel is an oblong hole, that is, the exhaust channel is formed as an oblong cavity.

[0017] In some technical solutions, optionally, at least a portion of the guide groove extends radially along the disc body; and / or at least a portion of the exhaust channel extends axially along the disc body.

[0018] In this technical solution, since at least part of the guide groove extends radially along the disc body and / or at least part of the exhaust channel extends axially along the disc body, the flow path of high-pressure gas during exhaust is extended, further reducing airflow impact, thereby reducing the aerodynamic noise generated during compressor exhaust, which in turn helps to reduce the overall noise of the compressor during operation.

[0019] In some technical solutions, the limiting component optionally includes a connecting hole, which is disposed opposite to and communicates with the exhaust channel along the axial direction of the disc body.

[0020] In this technical solution, the limiting component includes a connecting hole. Specifically, the connecting hole and the exhaust channel are axially opposite each other on the disc body, and the connecting hole is connected to the exhaust channel. That is to say, when the compressor discharges, the high-pressure gas impacts the check valve, causing the check valve to move away from the exhaust hole to open the exhaust hole. The high-pressure gas is discharged through the exhaust hole, the guide groove, the exhaust channel and the connecting hole respectively. This can effectively reduce the high-frequency knocking sound of the check valve while ensuring the normal discharge of the compressor. In addition, it can also reduce the direct impact of the high-pressure airflow on the top parts of the compressor, thereby significantly reducing the operating noise of the entire compressor.

[0021] In some technical solutions, optionally, at least a portion of the connecting hole extends circumferentially along the disk body; and / or radially along the disk body, the connecting hole includes opposing first and second hole walls, at least one of the first and second hole walls being configured as an arcuate wall.

[0022] In this technical solution, since at least part of the connecting hole extends along the circumference of the disc, the flow cross-sectional area of ​​the connecting hole is increased, thus ensuring the exhaust efficiency of the compressor.

[0023] The connecting hole includes a first hole wall and a second hole wall, wherein the first hole wall and the second hole wall are opposite each other along the radial direction of the disk body. Specifically, the first hole wall is an arc-shaped wall, or the second hole wall is an arc-shaped wall, or both the first hole wall and the second hole wall are arc-shaped walls. The specific configuration can be determined according to actual needs. Optionally, the connecting hole is an oblong hole or an elliptical hole.

[0024] In some technical solutions, optionally, the flow cross-sectional area of ​​the connecting hole is greater than or equal to the flow cross-sectional area of ​​the exhaust channel.

[0025] In this technical solution, since the flow cross-sectional area of ​​the connecting hole is greater than or equal to the flow cross-sectional area of ​​the exhaust channel, the smoothness of the compressor's exhaust can be improved, thereby ensuring the compressor's exhaust efficiency.

[0026] Optionally, the cross-sectional shape of the connecting hole is the same as the cross-sectional shape of the exhaust passage.

[0027] In some technical solutions, the limiting component optionally includes a limiting member and a connecting member, wherein the limiting member is provided with a communicating hole, the limiting member is connected to the disk body through the connecting member, and the connecting member is configured to be staggered from the communicating hole.

[0028] In this technical solution, the limiting component is defined to include a limiting member and a connecting member. Specifically, the limiting member is connected to the disc body through the connecting member, thereby achieving reliable assembly between the limiting member and the disc body. During the installation process, the check valve can be placed in the movable cavity first, and then the limiting member can be connected to the disc body through the connecting member, thereby solving the problem that the check valve is easy to fall off during the installation process, which helps to reduce the installation difficulty of the compressor and improve the assembly efficiency.

[0029] The connector and the connecting hole are staggered, which effectively avoids the problem of the connector blocking the connecting hole and affecting the compressor's discharge when the compressor is discharging, thus ensuring the compressor's efficiency.

[0030] In some technical solutions, optionally, at least a portion of the connector is located outside the connecting hole along the radial direction of the disk body; or the connector and the connecting hole are arranged circumferentially along the disk body.

[0031] In this technical solution, at least some of the connectors are located outside the connecting hole, and / or the connectors and the connecting hole are arranged circumferentially along the disc body, that is, the connectors and the connecting hole are completely staggered, so as to effectively avoid the connectors from blocking the connecting hole, and ensure the compressor can exhaust smoothly while achieving reliable assembly between the limiting component and the disc body.

[0032] In some technical solutions, the limiting member may optionally include a pad and a limiting part, wherein the pad is connected to the disc body through a connector, a connecting hole is provided in the pad, and the limiting part is provided on the side of the pad facing the check valve and is at least partially embedded in the movable cavity.

[0033] In this technical solution, the limiting component is defined as including a pad and a limiting part. Specifically, the limiting part is located on the side of the pad facing the check valve. That is, when the compressor discharges, the high-pressure gas impacts the check valve, causing the check valve to move away from the discharge port. When the discharge port is opened, the check valve can abut against the limiting part to limit the movement distance of the check valve in the moving chamber, thereby preventing the check valve from falling out and avoiding jamming or wear of the check valve during the process of rising or falling under the impact of high-pressure gas. This ensures that the check valve can fall back smoothly to cover the discharge port when the compressor is running under under-compression conditions or when the compressor stops.

[0034] Since at least part of the limiting part is embedded in the moving cavity, the limiting part can be limited in the radial direction, which helps to improve the assembly stability and reliability between the limiting part and the disc body. It avoids the situation where the limiting part and the disc body become loose or separate due to repeated impacts of the check valve on the limiting part, which would lead to the failure of the limiting part to limit the check valve. This helps to further improve the reliability of the compressor.

[0035] Optionally, the limiting part and the pad are an integral structure.

[0036] In some technical solutions, the disc body may optionally be provided with a limiting groove. The limiting groove is located on the side of the exhaust channel away from the exhaust hole. Along the radial direction of the disc body, the limiting groove is located on the outside of the movable cavity, and the pad is located inside the limiting groove.

[0037] In this technical solution, since the pad is located in the limiting groove, the limiting component can be limited in the radial and axial directions, which further improves the assembly stability and reliability between the limiting component and the disc body. This avoids the situation where the limiting component and the disc body become loose or separate due to repeated impacts of the check valve on the limiting part, which would lead to the failure of the limiting component to limit the check valve. This is conducive to further improving the reliability of the compressor.

[0038] Moreover, since the fitting between the limiting component and the disc is reliable, the vibration noise generated between the limiting component and the disc during the impact of the check valve on the limiting part can be reduced, which is conducive to further reducing the overall noise of the compressor during operation.

[0039] In some technical solutions, the connecting member may optionally include a first connecting member located on the side of the limiting member away from the check valve and abutting against the limiting member; the disc body is also provided with a mounting groove, and a portion of the first connecting member is embedded in the mounting groove.

[0040] This technical solution defines an assembly method between the limiting member and the disc body. Specifically, the connecting member includes a first connecting member, which is located on the side of the limiting member away from the check valve and abuts against the limiting member. A portion of the first connecting member is embedded in the mounting groove, thereby clamping the limiting member between the first connecting member and the disc body. The structure is simple, easy to operate, and helps to improve assembly efficiency.

[0041] Optionally, the first connector has an opening that extends radially through the first connector, giving it a certain degree of elasticity. This helps reduce the installation difficulty of the first connector and further improves the overall installation efficiency of the compressor.

[0042] Optionally, the first connector includes an elastic element.

[0043] Optionally, along the circumferential direction of the first connector, the first connector includes a first end and a second end, with a certain distance between the first end and the second end to form an opening. The first end has a first mounting hole, and the second end has a second mounting hole. During installation, an auxiliary tool is inserted into the first mounting hole and the second mounting hole respectively, narrowing the width of the opening. Then, by partially embedding the first connector into the mounting groove, the auxiliary tool is removed from the first and second mounting holes. The first connector, possessing a certain elasticity, quickly springs back and snaps into the mounting groove, thereby achieving rapid installation of the first connector. That is, the first connector is a retaining spring.

[0044] In some technical solutions, the first connecting member optionally includes a retaining ring.

[0045] In this technical solution, the use of a retaining ring as the first connecting component helps to further reduce the installation difficulty of the compressor and improve the overall assembly efficiency. Furthermore, placing the first connecting component on the retaining ring ensures reliable assembly between the limiting component and the disc body while also reducing the production cost of the compressor.

[0046] In some technical solutions, the connector may optionally include a second connector, and the limiting member may also have a connecting hole through which the second connector passes and is connected to the disc body.

[0047] This technical solution defines an alternative assembly method between the limiting component and the disc body. Specifically, the connector includes a second connector that passes through a connecting hole and connects to the disc body, thereby achieving a fixed assembly between the limiting component and the disc body. The structure is simple, easy to operate, and installation is faster and more efficient.

[0048] Optionally, the second connector includes a screw or bolt. The disc body also has a threaded hole through which the second connector passes and is connected.

[0049] Optionally, there may be multiple connecting holes, with each connecting hole corresponding to a different exhaust channel.

[0050] Optionally, there may be multiple connecting holes, with at least one connecting hole located between any two adjacent connecting holes. The number of second connectors corresponds to the number of connecting holes.

[0051] In some technical solutions, the limiting component may optionally include a vent, one end of which is connected to the movable cavity, and the other end of which passes through the limiting component.

[0052] In this technical solution, the limiting component is further defined as having a return air hole. Specifically, one end of the return air hole is connected to the movable cavity, and the other end passes through the limiting component. It can be understood that the other end of the return air hole is connected to the exhaust cavity.

[0053] Specifically, when the compressor discharges gas, the high-pressure gas impacts the check valve, causing the check valve to move away from the exhaust port, thereby opening the exhaust port. The high-pressure gas then flows through the guide groove, the exhaust channel, and the connecting hole in sequence before being discharged.

[0054] When the compressor is operating under undercompression conditions or when the compressor stops, the high-pressure gas flows back through the return gas hole on the limit component, impacting the check valve and moving it towards the side closer to the exhaust port. This causes the check valve to fall back quickly to cover the exhaust port, thereby preventing high-pressure gas from flowing back from the exhaust port into the compression chamber, reducing the operating noise of the compressor, preventing the compressor from reversing when it stops, and improving the reliability of the compressor.

[0055] Optionally, when the connector includes a first connector, the return air hole includes a first return air channel and a second return air channel. The first return air channel is disposed on the first connector, and the second return air channel is disposed on the limiting member. The first return air channel and the second return air channel are connected to form a return air hole.

[0056] Optionally, if the connector includes a second connector, the vent is provided on the limiting member.

[0057] In some technical solutions, the disc body may optionally include a disc body and a valve seat, wherein the disc body is provided with an exhaust hole, the valve seat is located on the disc body, and the valve seat is provided with a guide groove, an exhaust channel and a movable cavity; the disc body and the valve seat are an integral structure.

[0058] In this technical solution, the disc body is defined as including a disc body and a valve seat. Specifically, the exhaust port is provided on the disc body, and optionally, the disc body and the moving disc form a compression chamber.

[0059] The guide groove, exhaust passage, and movable chamber are respectively set on the valve seat, and the valve seat and disc body are an integral structure. This integrated design improves the machining accuracy and coaxiality of the disc body, reducing the risk of the check valve jamming due to machining and assembly precision issues during the sliding motion of the check valve within the movable chamber to open or close the exhaust port. Furthermore, the integrated structure facilitates mass production of the disc body, helping to reduce compressor production costs.

[0060] In some technical solutions, optionally, a return air groove is provided on the side of the check valve away from the exhaust port, and the return air groove is connected to the moving chamber.

[0061] In this technical solution, since a return gas groove is provided on the side of the check valve away from the exhaust port, and the return gas groove is connected to the moving chamber, when the compressor is running under under-compression conditions or when the compressor stops, the high-pressure gas flows back and impacts the check valve to move towards the side closer to the exhaust port. When the check valve covers the exhaust port, the contact area between the high-pressure gas and the check valve can be increased, so that the check valve can move quickly towards the side where the exhaust port is located. That is, when the compressor is running under under-compression conditions or when the compressor stops, the check valve can be made to fall quickly, which is beneficial to further improve the reliability of the compressor.

[0062] According to a second aspect of the present invention, a compressor is provided, including a stationary disc structure as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the stationary disc structure, which will not be repeated here.

[0063] According to a third aspect of this utility model, a refrigeration device is provided, including a stationary disc structure or compressor as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the stationary disc structure or compressor, which will not be repeated here.

Detailed Implementation

[0081] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0082] Many specific details are set forth in the following description in order to provide 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.

[0083] The following reference Figures 1 to 13 This invention describes a static disk structure 100, a compressor, and a refrigeration device provided according to some embodiments of the present invention.

[0084] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, a static disk structure 100 is proposed. The static disk structure 100 includes a disk body 110. The disk body 110 is provided with an exhaust hole 111, a guide groove 112, an exhaust channel 113, and a movable cavity 114. The guide groove 112 is located between the exhaust hole 111 and the movable cavity 114 along the radial direction of the disk body 110. The exhaust channel 113 is located outside the movable cavity 114. One end of the exhaust channel 113 is connected to the guide groove 112, and the other end of the exhaust channel 113 penetrates the disk body 110. A check valve 120 is movably disposed within the movable cavity 114 to open or close the vent hole 111; a limiting component 130 is connected to the disc body 110 and located on the side of the check valve 120 away from the vent hole 111; wherein, when the check valve 120 opens the vent hole 111, the vent hole 111 communicates with the guide groove 112, and the check valve 120 can abut against the limiting component 130; when the check valve 120 closes the vent hole 111, the vent hole 111 is closed from the guide groove 112.

[0085] The static disc structure 100 provided in this embodiment of the utility model includes a disc body 110, a check valve 120, and a limiting component 130. Specifically, the disc body 110 is provided with an exhaust port 111. Optionally, the disc body 110 and the moving disc form a compression chamber, and the compression chamber is connected to the exhaust port 111. Specifically, during the operation of the compressor, the moving disc rotates relative to the disc body 110 to compress the gas in the compression chamber. When the gas pressure in the compression chamber reaches the exhaust pressure, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 111 to the exhaust chamber, and finally discharged from the exhaust chamber to the outside of the compressor housing.

[0086] The check valve 120 can move within the movable chamber 114 to open or close the exhaust port 111. Specifically, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing the check valve 120 to move away from the exhaust port 111 to open the exhaust port 111. The high-pressure gas is discharged through the exhaust port 111, the guide groove 112, and the exhaust passage 113, respectively.

[0087] When the compressor operates under under-compression conditions or when the compressor stops, the high-pressure gas flows back, impacting the check valve 120 and moving it towards the side closer to the exhaust port 111 to cover the exhaust port 111. This shuts off the exhaust port 111 and the guide groove 112, thus preventing the high-pressure gas from flowing back into the compression chamber from the exhaust port 111. This effectively solves the problem of high compressor noise caused by high-pressure gas backflow when the compressor is operating under under-compression conditions, and also avoids the problem of compressor reversal caused by high-pressure gas backflow when the compressor stops. This reduces the high and low pressure balancing time and improves the reliability of the compressor.

[0088] Because a limiting component 130 is provided on the side of the check valve 120 away from the exhaust port 111, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing it to move away from the exhaust port 111. When the exhaust port 111 is opened, the check valve 120 can abut against the limiting component 130, thus limiting its movement within the movable chamber 114. This prevents the check valve 120 from coming off and avoids jamming or wear during its ascent or descent under the impact of high-pressure gas. This ensures that the check valve 120 can smoothly fall back to cover the exhaust port 111 when the compressor is operating under under-compression conditions or when it stops. Furthermore, during installation, the check valve 120 can be placed in the movable chamber 114 first, and then the limiting component 130 can be installed. This solves the problem of the check valve 120 easily falling off during installation, reducing the installation difficulty of the compressor and improving assembly efficiency.

[0089] In addition, since the disc body 110 is provided with an exhaust channel 113 and a guide groove 112, and the exhaust channel 113 is located on the radial outer side of the movable cavity 114, when the compressor exhausts, the high-pressure gas flowing out from the exhaust hole 111 impacts the check valve 120, causing the exhaust hole 111 to be opened. At the same time, the high-pressure gas flows out through the guide groove 112 and the exhaust channel 113. In other words, the high-pressure gas flowing out from the exhaust hole 111 is diverted, which can effectively reduce the high-frequency knocking sound of the check valve 120. At the same time, it can also reduce the direct impact of the high-pressure airflow on the top parts of the compressor, thereby significantly reducing the overall operating noise of the compressor.

[0090] like Figure 3 , Figure 5 , Figure 9 and Figure 11 As shown, in some embodiments, optionally, there are multiple exhaust channels 113, which are arranged circumferentially along the disc body 110, and the multiple exhaust channels 113 are respectively connected to the guide groove 112.

[0091] In this embodiment, the number of exhaust channels 113 is limited to a plurality of channels. Specifically, the plurality of exhaust channels 113 are arranged along the circumference of the disc body 110, and the plurality of exhaust channels 113 are respectively connected to the guide groove 112.

[0092] Specifically, when the compressor discharges, the high-pressure gas flowing out from the discharge port 111 impacts the check valve 120, causing the discharge port 111 to open. At the same time, the high-pressure gas flows out through the guide groove 112 and multiple discharge channels 113, which diverts the high-pressure gas flowing out from the discharge port 111. This reduces the high-frequency knocking sound of the check valve 120, slows down the direct impact of the high-pressure airflow on the top parts of the compressor, and thus reduces the overall operating noise of the compressor while ensuring the discharge efficiency of the compressor to meet the cooling or heating requirements.

[0093] Optionally, the cross-sectional shape of the exhaust channel 113 is an oblong hole, that is, the exhaust channel 113 is formed as an oblong cavity.

[0094] like Figure 1 , Figure 4 , Figure 8 and Figure 10 As shown, in some embodiments, optionally, at least a portion of the flow channel 112 extends radially along the disc body 110; and / or at least a portion of the exhaust channel 113 extends axially along the disc body 110.

[0095] In this embodiment, since at least a portion of the guide groove 112 extends radially along the disc body 110 and / or at least a portion of the exhaust channel 113 extends axially along the disc body 110, the flow path of the high-pressure gas during exhaust is extended, further mitigating the airflow impact, thereby reducing the aerodynamic noise generated during compressor exhaust, which in turn helps to reduce the overall noise of the compressor during operation.

[0096] like Figure 1 and Figure 8 As shown, in some embodiments, optionally, the limiting component 130 includes a connecting hole 131 along the axial direction of the disc body 110, the connecting hole 131 being disposed opposite to and communicating with the exhaust channel 113.

[0097] In this embodiment, the limiting component 130 includes a connecting hole 131. Specifically, the connecting hole 131 and the exhaust channel 113 are axially opposite to each other along the disc body 110, and the connecting hole 131 is connected to the exhaust channel 113. That is, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing the check valve 120 to move away from the exhaust hole 111 to open the exhaust hole 111. The high-pressure gas is discharged through the exhaust hole 111, the guide groove 112, the exhaust channel 113 and the connecting hole 131, respectively. This can effectively reduce the high-frequency knocking sound of the check valve 120 while ensuring the normal discharge of the compressor. In addition, it can also reduce the direct impact of the high-pressure airflow on the top parts of the compressor, thereby significantly reducing the overall operating noise of the compressor.

[0098] like Figure 2 , Figure 6 and Figure 12 As shown, in some embodiments, optionally, at least a portion of the connecting hole 131 extends circumferentially along the disk body 110; and / or radially along the disk body 110, the connecting hole 131 includes opposing first hole walls 132 and second hole walls 133, at least one of the first hole walls 132 and the second hole walls 133 being configured as an arcuate wall.

[0099] In this embodiment, since at least part of the connecting hole 131 extends circumferentially along the disc body 110, the flow cross-sectional area of ​​the connecting hole 131 is increased, thereby ensuring the exhaust efficiency of the compressor.

[0100] The connecting hole 131 includes a first hole wall 132 and a second hole wall 133, wherein the first hole wall 132 and the second hole wall 133 are radially opposite to each other along the disk body 110. Specifically, the first hole wall 132 is an arc-shaped wall, or the second hole wall 133 is an arc-shaped wall, or both the first hole wall 132 and the second hole wall 133 are arc-shaped walls. The specific configuration can be determined according to actual needs. Optionally, the connecting hole 131 can be an oblong hole or an elliptical hole.

[0101] In some embodiments, the flow cross-sectional area of ​​the connecting hole 131 is optionally greater than or equal to the flow cross-sectional area of ​​the exhaust channel 113.

[0102] In this embodiment, since the flow cross-sectional area of ​​the connecting hole 131 is greater than or equal to the flow cross-sectional area of ​​the exhaust channel 113, the smoothness of the compressor exhaust can be improved, thereby ensuring the exhaust efficiency of the compressor.

[0103] Optionally, the cross-sectional shape of the connecting hole 131 is the same as the cross-sectional shape of the exhaust channel 113.

[0104] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the limiting component 130 includes a limiting member 134 and a connecting member 135, wherein the limiting member 134 is provided with a communicating hole 131, the limiting member 134 is connected to the disk body 110 through the connecting member 135, and the connecting member 135 is configured to be staggered from the communicating hole 131.

[0105] In this embodiment, the limiting component 130 is defined to include a limiting member 134 and a connecting member 135. Specifically, the limiting member 134 is connected to the disc body 110 through the connecting member 135, thereby achieving reliable assembly between the limiting member 134 and the disc body 110. During the installation process, the check valve 120 can be placed in the movable cavity 114 first, and then the limiting member 134 can be connected to the disc body 110 through the connecting member 135. This solves the problem that the check valve 120 is easy to fall off during the installation process, which helps to reduce the installation difficulty of the compressor and improve the assembly efficiency.

[0106] The connector 135 is offset from the connecting hole 131, so that when the compressor is discharging, the problem of the connector 135 blocking the connecting hole 131 and affecting the compressor's discharge can be effectively avoided, thus ensuring the compressor's efficiency.

[0107] like Figure 2 , Figure 9 and Figure 12 As shown, in some embodiments, optionally, at least a portion of the connector 135 is located outside the communication hole 131 along the radial direction of the disk body 110; or the connector 135 and the communication hole 131 are arranged circumferentially along the disk body 110.

[0108] In this embodiment, at least some of the connectors 135 are located outside the connecting hole 131, and / or the connectors 135 and the connecting hole 131 are arranged circumferentially along the disc body 110, that is, the connectors 135 and the connecting hole 131 are completely staggered, thereby effectively preventing the connectors 135 from blocking the connecting hole 131, and ensuring that the compressor can discharge smoothly while achieving reliable assembly between the limiting member 134 and the disc body 110.

[0109] like Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the limiting member 134 includes a pad 136 and a limiting part 137, wherein the pad 136 is connected to the disc body 110 through a connector 135, a connecting hole 131 is provided in the pad 136, and the limiting part 137 is provided on the side of the pad 136 facing the check valve 120 and is at least partially embedded in the movable cavity 114.

[0110] In this embodiment, the limiting member 134 includes a pad 136 and a limiting part 137. Specifically, the limiting part 137 is disposed on the side of the pad 136 facing the check valve 120. That is, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing the check valve 120 to move away from the exhaust port 111. When the exhaust port 111 is opened, the check valve 120 can abut against the limiting part 137 to limit the check valve 120, thereby limiting the movement distance of the check valve 120 in the movable chamber 114, preventing the check valve 120 from coming out, and avoiding the check valve 120 from getting stuck or wearing during the process of rising or falling under the impact of high-pressure gas. This ensures that when the compressor is running under under-compression conditions or when the compressor stops, the check valve 120 can fall back smoothly to cover the exhaust port 111.

[0111] Since at least part of the limiting part 137 is embedded in the movable cavity 114, the limiting part 137 can be limited in the radial direction, which helps to improve the assembly stability and reliability between the limiting member 134 and the disc 110. It avoids the situation where the limiting member 134 and the disc 110 become loose or separate due to the repeated impact of the check valve 120 on the limiting part 137, which would lead to the failure of the limiting member 134 to limit the check valve 120. This helps to further improve the reliability of the compressor.

[0112] Optionally, the limiting part 137 and the pad 136 are an integral structure.

[0113] like Figure 1 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10As shown, in some embodiments, optionally, the disc body 110 is also provided with a limiting groove 115. The limiting groove 115 is located on the side of the exhaust channel 113 away from the exhaust hole 111. Along the radial direction of the disc body 110, the limiting groove 115 is located outside the movable cavity 114, and the pad 136 is located inside the limiting groove 115.

[0114] In this embodiment, since the pad 136 is located within the limiting groove 115, it can limit the limiting member 134 in the radial and axial directions, further improving the assembly stability and reliability between the limiting member 134 and the disc 110. This avoids the situation where the limiting member 134 and the disc 110 become loose or separate due to repeated impacts of the check valve 120 on the limiting part 137, which would lead to the failure of the limiting member 134 to limit the check valve 120. This is beneficial to further improve the reliability of the compressor.

[0115] Furthermore, since the limiting member 134 and the disc body 110 are reliably assembled, the vibration noise generated between the limiting member 134 and the disc body 110 during the impact of the check valve 120 on the limiting part 137 can be reduced, which is conducive to further reducing the overall noise of the compressor during operation.

[0116] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, optionally, the connector 135 includes a first connector 138, which is located on the side of the limit member 134 away from the check valve 120 and abuts against the limit member 134; the disc body 110 is also provided with a mounting groove 116, and a portion of the first connector 138 is embedded in the mounting groove 116.

[0117] In this embodiment, an assembly method is defined between the limiting member 134 and the disc body 110. Specifically, the connecting member 135 includes a first connecting member 138, which is located on the side of the limiting member 134 away from the check valve 120 and abuts against the limiting member 134. A portion of the first connecting member 138 is embedded in the mounting groove 116, thereby clamping the limiting member 134 between the first connecting member 138 and the disc body 110. The structure is simple, easy to operate, and conducive to improving assembly efficiency.

[0118] Optionally, the first connector 138 is provided with an opening that extends radially through the first connector 138, giving the first connector 138 a certain degree of elasticity, which helps to reduce the installation difficulty of the first connector 138 and further improve the installation efficiency of the entire compressor.

[0119] Optionally, the first connector 138 includes an elastic element.

[0120] Optionally, along the circumferential direction of the first connector 138, the first connector 138 includes a first end and a second end, with a certain distance between the first end and the second end to form an opening. The first end has a first mounting hole, and the second end has a second mounting hole. During installation, an auxiliary tool is inserted into the first mounting hole and the second mounting hole respectively, narrowing the width of the opening. Then, by partially embedding the first connector 138 into the mounting groove 116, the auxiliary tool is removed from the first mounting hole and the second mounting hole. The elastic first connector 138 quickly springs back and snaps into the mounting groove 116, thereby achieving rapid installation of the first connector 138. That is, the first connector 138 is a retaining spring.

[0121] like Figure 3 As shown, in some embodiments, the first connector 138 may optionally include a retaining ring.

[0122] In this embodiment, since the first connecting member 138 is a retaining ring, it helps to further reduce the installation difficulty of the compressor and improve the assembly efficiency of the whole machine. Moreover, setting the first connecting member 138 on the retaining ring not only ensures reliable assembly between the limiting member 134 and the disc 110, but also helps to reduce the production cost of the compressor.

[0123] like Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, optionally, the connector 135 includes a second connector 139, and the limiting member 134 is further provided with a connecting hole 140, through which the second connector 139 passes and is connected to the disc body 110.

[0124] In this embodiment, an alternative assembly method is defined between the limiting member 134 and the disk body 110. Specifically, the connector 135 includes a second connector 139, which passes through the connecting hole 140 and connects to the disk body 110, thereby achieving a fixed assembly between the limiting member 134 and the disk body 110. The structure is simple, easy to operate, and installation is faster and more efficient.

[0125] Optionally, the second connector 139 includes a screw or bolt. The disc body 110 also has a threaded hole through which the second connector 139 passes and is connected to the threaded hole.

[0126] Optionally, there are multiple connecting holes 131, and each of the multiple connecting holes 131 corresponds to a multiple exhaust channel 113.

[0127] Optionally, there may be multiple connecting holes 140, with at least one connecting hole 140 located between any two adjacent connecting holes 131. The number of second connectors 139 corresponds to the number of connecting holes 140.

[0128] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, in some embodiments, the limiting component 130 may optionally include a vent 150, one end of which is connected to the movable cavity 114, and the other end of which is connected to the limiting component 130.

[0129] In this embodiment, the limiting component 130 is further defined as having a return air hole 150. Specifically, one end of the return air hole 150 is connected to the movable cavity 114, and the other end passes through the limiting component 130. It can be understood that the other end of the return air hole 150 is connected to the exhaust cavity.

[0130] Specifically, when the compressor discharges gas, the high-pressure gas impacts the check valve 120, causing the check valve 120 to move away from the exhaust port 111, thereby opening the exhaust port 111. The high-pressure gas then flows through the guide groove 112, the exhaust channel 113, and the connecting hole 131 in sequence before being discharged.

[0131] When the compressor operates under under-compression conditions or when the compressor stops, high-pressure gas flows back through the return gas hole 150 on the limit assembly 130, impacting the check valve 120 and moving it towards the side closer to the exhaust hole 111. This causes the check valve 120 to fall back quickly to cover the exhaust hole 111, thereby preventing high-pressure gas from flowing back into the compression chamber from the exhaust hole 111, reducing the operating noise of the compressor, preventing the compressor from reversing when it stops, and improving the reliability of the compressor.

[0132] Optionally, when the connector 135 includes the first connector 138, the return air hole 150 includes a first return air channel and a second return air channel. The first return air channel is disposed on the first connector 138, and the second return air channel is disposed on the limiting member 134. The first return air channel and the second return air channel are connected to form the return air hole 150.

[0133] Optionally, if the connector 135 includes a second connector 139, the vent 150 is provided on the limiting member 134.

[0134] like Figure 1 , Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, optionally, the disc body 110 includes a disc body 117 and a valve seat 118, wherein the disc body 117 is provided with an exhaust hole 111, the valve seat 118 is provided on the disc body 117, and the valve seat 118 is provided with a guide groove 112, an exhaust channel 113 and a movable cavity 114; the disc body 117 and the valve seat 118 are an integral structure.

[0135] In this embodiment, the disc body 110 is defined as including a disc body 117 and a valve seat 118. Specifically, an exhaust port 111 is provided on the disc body 117. Optionally, the disc body 117 and the moving disc form a compression chamber.

[0136] The guide groove 112, exhaust passage 113, and movable chamber 114 are respectively disposed on the valve seat 118, and the valve seat 118 and the disc body 117 are an integral structure. That is to say, by designing the valve seat 118 and the disc body 117 as an integral unit, the machining accuracy and coaxiality of the disc body 110 can be improved. This reduces the problem of the check valve 120 getting stuck due to parts machining and assembly accuracy issues during the process of the check valve 120 sliding up and down in the movable chamber 114 to open or close the exhaust port 111. In addition, the integral structure also facilitates the mass production of the disc body 110, which helps to reduce the production cost of the compressor.

[0137] like Figure 1 , Figure 3 , Figure 8 and Figure 9 As shown, in some embodiments, optionally, the check valve 120 is provided with a return air groove 121 on the side opposite to the exhaust port 111, and the return air groove 121 is connected to the movable chamber 114.

[0138] In this embodiment, since the check valve 120 is provided with a return gas groove 121 on the side away from the exhaust port 111, and the return gas groove 121 is connected to the movable chamber 114, when the compressor is running under under-compression conditions or when the compressor stops, the high-pressure gas flows back and impacts the check valve 120 to move towards the side closer to the exhaust port 111 to cover the exhaust port 111. This can increase the contact area between the high-pressure gas and the check valve 120, so that the check valve 120 can move quickly towards the side where the exhaust port 111 is located. That is, when the compressor is running under under-compression conditions or when the compressor stops, it can cause the check valve 120 to fall back quickly, which is beneficial to further improve the reliability of the compressor.

[0139] In a specific embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the stationary scroll (stationary scroll structure 100) is fixedly installed on the compressor. The upper part of the stationary scroll exhaust port (exhaust hole 111) is provided with a middle cavity (movable cavity 114) and three waist-shaped cavities (exhaust channels 113). The middle cavity (movable cavity 114) is equipped with a check valve column (check valve 120). The check valve column (check valve 120) slides up and down along the inner wall of the middle cavity (movable cavity 114). The bottom of the middle cavity (movable cavity 114) is provided with a guide groove 112. The guide groove 112 is connected to the three waist-shaped cavities (exhaust channels 113). The middle cavity (movable cavity 114) is connected to the bottom guide groove 112.

[0140] The top of the hub of the stationary disc (disc body 117) (valve seat 118) is provided with a retaining ring groove (mounting groove 116). The pad (limiting member 134) is connected to the stationary disc (disc body 110) through the retaining ring (first connecting member 138). The pad is provided with 3 waist-shaped holes (connecting holes 131) that communicate with the waist-shaped cavity (exhaust channel 113) of the stationary disc (disc body 110). A return air hole 150 is provided in the middle of the pad (limiting member), and the return air hole 150 communicates with the middle cavity (movable cavity 114).

[0141] The check valve column (check valve 120) slides up and down on the inner wall of the middle cavity (movable cavity 114) according to the different suction and discharge pressures of the compressor. The middle cavity (valve seat 118) and the stationary plate (plate body 117) are designed as an integral unit.

[0142] Furthermore, the connection between the pad (limiting member 134) and the stationary disc (disc body 110) can be fixed by a snap ring (first connecting member 138), or by a locking screw (second connecting member 139). The check valve structure provided in this application reduces high-frequency exhaust noise and solves problems such as the valve stem (check valve 120) falling off during installation and easily getting stuck during vertical sliding. It is easy to install and has a simple structure.

[0143] To avoid high-frequency noise generated during the exhaust operation of the scroll plate, this application proposes an exhaust check valve structure design with noise reduction effect. This design integrates the valve seat 118 and the stationary plate (plate body 117) into a single unit, achieving high machining precision and good coaxiality. The valve stem (check valve 120) slides up and down within the intermediate cavity (movable cavity 114) of the stationary plate (plate body 110), reducing the problem of valve stem (check valve 120) jamming caused by issues related to component machining and assembly precision. Simultaneously, this design avoids the problem of valve stems easily falling off during traditional installation processes.

[0144] Furthermore, the high-pressure gas, after being compressed by the vortex, is discharged through the stationary disc exhaust port (exhaust hole 111). The high-pressure gas pushes up the valve column (check valve 120), and the gas flows through the guide groove 112 and then through the waist-shaped cavity (exhaust channel 113) around the stationary disc (disc body 110), and then is discharged through the waist-shaped hole (connecting hole 131) on the pad (limiting member 134). This reduces the direct impact of the airflow on the top parts of the compressor, avoiding high-frequency resonance with the top parts on the one hand, and reducing the high-frequency striking sound of the valve plate (check valve 120) on the other hand, thus reducing the noise of the compressor. At the same time, a retaining ring groove (installation groove 116) is opened on the top of the hub of the stationary disc (disc body 110), and the pad (limiting member 134) is fixed to the stationary disc (disc body 110) through the retaining ring (first connecting member 138), making the operation simpler and the installation faster and more efficient.

[0145] According to a second aspect of the present invention, a compressor is provided, including the stationary disc structure 100 as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the stationary disc structure 100, which will not be repeated here.

[0146] Furthermore, the compressor also includes a moving plate, and the plate body 110 and the moving plate form a compression chamber. The compression chamber is connected to the exhaust port 111. Specifically, during the operation of the compressor, the moving plate rotates relative to the plate body 110 to compress the gas in the compression chamber. When the gas pressure in the compression chamber reaches the exhaust pressure, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 111 to the exhaust chamber, and finally discharged from the exhaust chamber to the outside of the compressor housing.

[0147] The check valve 120 can move within the movable chamber 114 to open or close the exhaust port 111. Specifically, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing the check valve 120 to move away from the exhaust port 111 to open the exhaust port 111. The high-pressure gas is discharged through the exhaust port 111, the guide groove 112, and the exhaust passage 113, respectively.

[0148] When the compressor operates under under-compression conditions or when the compressor stops, the high-pressure gas flows back, impacting the check valve 120 and moving it towards the side closer to the exhaust port 111 to cover the exhaust port 111. This shuts off the exhaust port 111 and the guide groove 112, thus preventing the high-pressure gas from flowing back into the compression chamber from the exhaust port 111. This effectively solves the problem of high compressor noise caused by high-pressure gas backflow when the compressor is operating under under-compression conditions, and also avoids the problem of compressor reversal caused by high-pressure gas backflow when the compressor stops. This reduces the high and low pressure balancing time and improves the reliability of the compressor.

[0149] Because a limiting component 130 is provided on the side of the check valve 120 away from the exhaust port 111, when the compressor discharges, the high-pressure gas impacts the check valve 120, causing it to move away from the exhaust port 111. When the exhaust port 111 is opened, the check valve 120 can abut against the limiting component 130, thus limiting its movement within the movable chamber 114. This prevents the check valve 120 from coming off and avoids jamming or wear during its ascent or descent under the impact of high-pressure gas. This ensures that the check valve 120 can smoothly fall back to cover the exhaust port 111 when the compressor is operating under under-compression conditions or when it stops. Furthermore, during installation, the check valve 120 can be placed in the movable chamber 114 first, and then the limiting component 130 can be installed. This solves the problem of the check valve 120 easily falling off during installation, reducing the installation difficulty of the compressor and improving assembly efficiency.

[0150] In addition, since the disc body 110 is provided with an exhaust channel 113 and a guide groove 112, and the exhaust channel 113 is located on the radial outer side of the movable cavity 114, when the compressor exhausts, the high-pressure gas flowing out from the exhaust hole 111 impacts the check valve 120, causing the exhaust hole 111 to be opened. At the same time, the high-pressure gas flows out through the guide groove 112 and the exhaust channel 113. In other words, the high-pressure gas flowing out from the exhaust hole 111 is diverted, which can effectively reduce the high-frequency knocking sound of the check valve 120. At the same time, it can also reduce the direct impact of the high-pressure airflow on the top parts of the compressor, thereby significantly reducing the overall operating noise of the compressor.

[0151] According to a third aspect of the present invention, a refrigeration device is provided, including a static disk structure 100 or a compressor as provided in any of the above embodiments, and thus possessing all the beneficial technical effects of the static disk structure 100 or the compressor, which will not be repeated here.
