Description

Technical Field

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

[0002] Currently, scroll compressors generally include a fixed scroll component and a moving scroll component. The scroll teeth of the moving scroll component and the scroll teeth of the fixed scroll component form a compression chamber. The gas in the compression chamber is compressed during the translational rotation of the moving scroll component relative to the fixed scroll component.

[0003] However, when the scroll compressor in the related technology is running or shut down under under-compression conditions, the refrigerant in the high-pressure chamber will flow back into the compression chamber, causing problems such as high operating noise, reverse rotation when shut down, and reduced reliability. Utility Model Content

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

[0005] Therefore, a first aspect of the embodiments of the present invention provides a static vortex disk assembly.

[0006] A second aspect of the embodiments of this utility model provides a compressor.

[0007] A third aspect of the embodiments of this utility model provides a refrigeration device.

[0008] In view of the above, according to a first aspect of the present invention, a stationary vortex assembly is provided, comprising: a stationary vortex, the stationary vortex having an exhaust port and an exhaust groove; a check valve column, movably disposed within the exhaust groove to open or close the exhaust port, the check valve column having an exhaust channel communicating with the exhaust groove; and a limiting member connected to the stationary vortex and located on the side of the check valve column opposite to the exhaust port; wherein, when the exhaust port is opened based on the check valve column, the exhaust port communicates with the exhaust groove, and the check valve column can abut against the limiting member; when the exhaust port is closed based on the check valve column, the exhaust port is cut off from the exhaust groove.

[0009] The stationary scroll assembly provided in this embodiment includes a stationary scroll, a check valve column, and a limiting member. Specifically, the stationary scroll is provided with an exhaust port. Optionally, the stationary scroll and the moving scroll form a compression chamber, which is connected to the exhaust port. Specifically, during the operation of the compressor, the moving scroll rotates relative to the stationary scroll 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 (i.e., the high-pressure chamber), and finally discharged from the exhaust chamber to the outside of the compressor housing.

[0010] In related technologies, when a scroll compressor operates under under-compression conditions or when the scroll compressor stops, the high-pressure gas in the exhaust chamber is prone to flow back into the compression chamber through the exhaust port, resulting in louder operating noise and reverse rotation when the scroll compressor stops, thus reducing the reliability of the scroll compressor.

[0011] The stationary volute is equipped with an exhaust groove, and the check valve column is movably installed in the exhaust groove to open or cover the exhaust port. Specifically, when the compressor exhausts, the high-pressure gas impacts the check valve column, causing the check valve column to move away from the exhaust port to open the exhaust port. The high-pressure gas is discharged through the exhaust port, the exhaust groove, and the exhaust passage respectively.

[0012] When the compressor operates under under-compression conditions or when the compressor stops, the high-pressure gas flows back, impacting the check valve column and moving it towards the side closer to the exhaust port to seal the exhaust port. This prevents high-pressure gas from flowing back from the exhaust port into the compression chamber, effectively solving the problem of high compressor noise caused by high-pressure gas backflow when the compressor is operating under under-compression conditions. It also prevents the compressor from reversing due to high-pressure gas backflow when the compressor stops, reducing the high and low pressure balancing time and improving the reliability of the compressor.

[0013] Because a limiting element is installed on the side of the check valve column away from the exhaust port, when the compressor discharges, the high-pressure gas impacts the check valve column, causing it to move away from the exhaust port. When the exhaust port is opened, the check valve column can abut against the limiting element to limit its movement within the exhaust groove, thus preventing it from coming out. This also avoids jamming or wear during the process of the check valve column rising or falling under the impact of high-pressure gas, ensuring that the check valve column can fall back smoothly to seal the exhaust port when the compressor is running under under-compression conditions or when the compressor stops.

[0014] Furthermore, since a limiting component is installed on the side of the check valve column away from the exhaust port, the problem of the check valve column falling off during compressor installation can be avoided, which helps to reduce the installation difficulty of the compressor and improve the installation efficiency of the compressor.

[0015] In some technical solutions, optionally, the limiting member is provided with a return air hole, one end of which is connected to the exhaust groove, and the other end of which passes through the limiting member.

[0016] In this technical solution, the limiting member is provided with a return air hole. Specifically, one end of the return air hole is connected to the exhaust groove, and the other end passes through the limiting member. It can be understood that the other end of the return air hole is connected to the exhaust chamber.

[0017] Specifically, when the compressor discharges gas, the high-pressure gas impacts the check valve column, causing the check valve column to move away from the exhaust port to open the exhaust port. The high-pressure gas is then discharged through the exhaust port, exhaust groove, exhaust passage, and return air hole.

[0018] When the compressor operates under undercompression conditions or when the compressor stops, the high-pressure gas flows back through the return gas hole on the limiting component, impacting the check valve column and moving it towards the side closer to the exhaust port to seal the exhaust port. This prevents the high-pressure gas from flowing back from the exhaust port into the compression chamber, reduces the operating noise of the compressor, prevents the compressor from reversing when it stops, and improves the reliability of the compressor.

[0019] In some technical solutions, optionally, along the radial direction of the stationary vortex disk, the distance between the wall of the return air hole and the wall of the exhaust groove is less than or equal to the distance between the side wall of the exhaust passage away from the central axis of the stationary vortex disk and the wall of the exhaust groove.

[0020] In this technical solution, the distance between the wall of the return air hole and the wall of the exhaust groove in the radial direction of the stationary scroll is d1, and the distance between the side wall of the exhaust passage away from the central axis of the stationary scroll and the wall of the exhaust groove in the radial direction of the stationary scroll is d2. Wherein, d1 is less than or equal to d2. That is to say, in the axial direction of the stationary scroll, the limiting component will not obstruct the exhaust passage on the check valve column, so that while limiting the check valve column, the exhaust of the compressor is not affected, thus ensuring the efficiency of the compressor.

[0021] In some technical solutions, optionally, the wall of the exhaust channel is provided with an installation groove, and a part of the limiting member is embedded in the installation groove.

[0022] In this technical solution, the exhaust channel wall is provided with an installation groove. Specifically, some of the limiting components are embedded in the installation groove, thereby realizing the assembly between the limiting components and the stationary scroll. Moreover, the structure is simple, which helps to reduce the installation difficulty and improve the installation efficiency of the entire compressor.

[0023] In some technical solutions, the mounting groove is optionally constructed as an annular groove.

[0024] In this technical solution, the mounting groove is defined as an annular groove. Since part of the limiting component is embedded in the annular groove, the contact area between the limiting component and the stationary scroll is increased, and the connection strength between the limiting component and the stationary scroll is improved. This avoids the situation where, when the compressor is discharging, the check valve column moves away from the exhaust port under the impact of high-pressure gas and comes into contact with the limiting component, causing the limiting component to detach from the stationary scroll. This helps to improve the installation reliability of the limiting component.

[0025] In some technical solutions, optionally, along the circumference of the check valve column, the limiting member includes a first end and a second end, with a gap between the first end and the second end.

[0026] In this technical solution, the limiting component includes a first end and a second end with a certain distance between them in the circumferential direction of the check valve column. That is to say, the limiting component has an opening that extends through the limiting component. This allows the limiting component to have a certain degree of elasticity while limiting the check valve column, which helps to reduce the installation difficulty of the limiting component and further improve the installation efficiency of the entire compressor.

[0027] In some technical solutions, the limiting member may optionally include a body, a first mounting part and a second mounting part. Along the circumference of the check valve column, the first mounting part and the second mounting part are respectively disposed at both ends of the body. The first mounting part includes a first end and the second mounting part includes a second end. The first mounting part is provided with a first mounting hole and the second mounting part is provided with a second mounting hole.

[0028] In this technical solution, the limiting member is further defined as including a body, a first mounting part and a second mounting part. Specifically, the first mounting part and the second mounting part are respectively disposed at both ends of the body in the circumferential direction, and the first mounting part includes a first end and the second mounting part includes a second end. That is to say, there is a gap between the first mounting part and the second mounting part along the circumferential direction of the check valve column to form an opening.

[0029] Since the first mounting part has a first mounting hole and the second mounting part has a second mounting hole, during installation, an auxiliary tool is inserted into the first mounting hole and the second mounting hole respectively, and the width of the opening is reduced. Then, by embedding part of the main body into the mounting groove, the auxiliary tool is removed from the first mounting hole and the second mounting hole. The limiting member with a certain elasticity quickly rebounds and is locked into the mounting groove, thereby realizing the rapid installation of the limiting member, which is conducive to improving the installation efficiency of the entire compressor.

[0030] In some technical solutions, the limiting element may optionally include an elastic element.

[0031] In this technical solution, since the limiting component is an elastic component, that is, the limiting component has a certain degree of elasticity, it can achieve reliable assembly between the limiting component and the stationary scroll while reducing the machining accuracy requirements of the mounting groove, thereby reducing the production cost of the compressor.

[0032] Furthermore, since the check valve column can abut against the limiting element when it opens the vent, the limit element is made elastic, which reduces wear between the check valve column and the limiting element during repeated movement of the check valve column, thus extending the service life of the check valve column.

[0033] In some technical solutions, the elastic element optionally includes a retaining ring.

[0034] In this technical solution, since the elastic element is a retaining ring, that is, the limiting element 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 limiting element as a retaining ring not only ensures reliable assembly between the limiting element and the stationary scroll, but also helps to reduce the production cost of the compressor.

[0035] In some technical solutions, optionally, the static vortex disc includes a disc body and a valve seat, wherein the disc body is provided with an exhaust port, the valve seat is located on the disc body, the valve seat is provided with an exhaust groove, and a limiting member is connected to the valve seat.

[0036] In this technical solution, the stationary vortex disc is defined as including a disc body and a valve seat. Specifically, the disc body is provided with an exhaust port, that is, the disc body and the moving vortex disc form a compression chamber.

[0037] The limiting component is connected to the valve seat. When the compressor discharges, the high-pressure gas impacts the check valve column, causing it to move away from the discharge port. When the discharge port is opened, the check valve column can abut against the limiting component to limit its movement. This restricts the movement distance of the check valve column within the discharge slot, preventing it from getting stuck or worn during the process of rising or falling due to the impact of high-pressure gas. This ensures that the check valve column can fall smoothly to seal the discharge port when the compressor is running under under-compression conditions or when it stops.

[0038] Optionally, the valve seat and the disc body are integrated into one structure, that is, the valve seat is integrated into the disc body. This can improve the installation and movement space of the return valve column, while reducing the number of parts and thus reducing the production cost of the compressor.

[0039] In some technical solutions, the check valve column may optionally include an outer wall extending axially along the stationary vortex, the outer wall being in clearance fit with the wall of the exhaust groove.

[0040] In this technical solution, the outer wall of the check valve column is fitted with the groove wall of the exhaust groove with a clearance. That is, there is a small gap between the outer wall of the check valve column and the groove wall of the exhaust groove. This ensures that the check valve column can move up and down smoothly in the exhaust groove to open or seal the exhaust port. In addition, it can also ensure the perpendicularity of the check valve column and the back of the stationary vortex plate, further preventing the check valve column from getting stuck or worn during the process of rising or falling under the impact of high pressure gas.

[0041] In some technical solutions, optionally, a return air groove is provided on the side of the check valve column away from the exhaust port. The return air groove is connected to the exhaust groove. Along the radial direction of the check valve column, the return air groove is located inside the exhaust channel.

[0042] In this technical solution, since a return gas groove is provided on the side of the check valve column away from the exhaust port, and the return gas groove is connected to the exhaust groove, 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 column to move towards the side closer to the exhaust port. When the check valve column is sealed, the contact area between the high-pressure gas and the check valve column can be increased, so that the check valve column can move quickly towards the side where the exhaust port is located. This further prevents the high-pressure gas from flowing back from the exhaust port into the compression chamber when the compressor is running under under-compression conditions or when the compressor stops.

[0043] In some technical solutions, optionally, there are multiple exhaust channels, which are arranged at intervals along the circumference of the check valve column and are connected to the exhaust groove respectively.

[0044] In this technical solution, the number of exhaust channels is limited to multiple. Specifically, multiple exhaust channels are arranged at intervals along the circumference of the check valve column, and each of the multiple exhaust channels is connected to the exhaust groove. When the compressor discharges, the high-pressure gas impacts the check valve column, causing the check valve column to move away from the exhaust port to open the exhaust port. The high-pressure gas is discharged through the exhaust port, the exhaust groove and the multiple exhaust channels, which helps to ensure the efficiency of the compressor during discharge.

[0045] In some technical solutions, optionally, along the radial direction of the check valve column, the exhaust passage includes opposing first and second walls, at least one of which is configured as an arcuate surface.

[0046] In this technical solution, the exhaust passage is defined to include a first wall surface and a second wall surface. Specifically, the first wall surface and the second wall surface are arranged opposite each other in the radial direction of the check valve column. Optionally, the first wall surface is close to the central axis of the stationary volute, and the second wall surface is far away from the central axis of the stationary volute. Alternatively, the first wall surface is far away from the central axis of the stationary volute, and the second wall surface is close to the central axis of the stationary volute.

[0047] Since at least one of the first and second walls is an arc-shaped surface, the cross-sectional area of ​​the exhaust passage can be increased, ensuring the efficiency of the compressor during exhaust and improving the stability and reliability of the compressor during operation.

[0048] Optionally, the cross-sectional shape of the exhaust passage is an oblong orifice.

[0049] According to a second aspect of this utility model, a compressor is provided, comprising a stationary scroll assembly as provided in any of the above-described technical solutions, thus possessing all the beneficial technical effects of the stationary scroll assembly, which will not be elaborated further here. Furthermore, the compressor also includes a moving scroll, the moving scroll and the stationary scroll forming a compression chamber, the compression chamber being connected to an exhaust port.

[0050] The stationary scroll and the moving scroll form a compression chamber, which is connected to the exhaust port. Specifically, during the operation of the compressor, the moving scroll rotates relative to the stationary scroll 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 (i.e., the high-pressure chamber), and finally discharged from the exhaust chamber to the outside of the compressor housing.

[0051] According to a third aspect of this utility model, a refrigeration device is provided, including a static scroll assembly or compressor as provided in any of the above technical solutions, and thus possesses all the beneficial technical effects of the static scroll assembly or compressor, which will not be repeated here.

Detailed Implementation

[0063] 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.

[0064] 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.

[0065] The following reference Figures 1 to 7 This invention describes a static scroll assembly 100, a compressor, and a refrigeration device provided according to some embodiments of the present invention.

[0066] In one embodiment according to this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a stationary vortex disk assembly 100 is proposed. The stationary vortex disk assembly 100 includes: a stationary vortex disk 110, which has an exhaust port 111 and an exhaust groove 112; a check valve column 120, which is movably disposed in the exhaust groove 112 to open or close the exhaust port 111, and the check valve column 120 has an exhaust channel 121 that communicates with the exhaust groove 112; and a limiting member 130, which is connected to the stationary vortex disk 110 and located on the side of the check valve column 120 away from the exhaust port 111; wherein, when the exhaust port 111 is opened based on the check valve column 120, the exhaust port 111 communicates with the exhaust groove 112, and the check valve column 120 can abut against the limiting member 130; when the exhaust port 111 is closed based on the check valve column 120, the exhaust port 111 is closed from the exhaust groove 112.

[0067] The stationary scroll assembly 100 provided in this embodiment of the present invention includes a stationary scroll 110, a check valve column 120, and a limiting member 130. Specifically, the stationary scroll 110 is provided with an exhaust port 111. Optionally, the stationary scroll 110 and the moving scroll 210 form a compression chamber 220, which is connected to the exhaust port 111. Specifically, during the operation of the compressor 200, the moving scroll 210 rotates relative to the stationary scroll 110 to compress the gas in the compression chamber 220. When the gas pressure in the compression chamber 220 reaches the exhaust pressure, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 111 to the exhaust chamber (i.e., the high-pressure chamber), and finally discharged from the exhaust chamber to the outside of the compressor 200 housing.

[0068] In related technologies, when a scroll compressor operates under under-compression conditions or when the scroll compressor stops, the high-pressure gas in the exhaust chamber is prone to flow back into the compression chamber through the exhaust port, resulting in louder operating noise and reverse rotation when the scroll compressor stops, thus reducing the reliability of the scroll compressor.

[0069] The stationary volute 110 is provided with an exhaust groove 112, and the check valve column 120 is movably disposed in the exhaust groove 112 to open or cover the exhaust port 111. Specifically, when the compressor 200 exhausts, the high-pressure gas impacts the check valve column 120, causing the check valve column 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 exhaust groove 112 and the exhaust passage 121 respectively.

[0070] When the compressor 200 operates under under-compression conditions, or when the compressor 200 stops, the high-pressure gas flows back and impacts the check valve column 120, moving it towards the side closer to the exhaust port 111 to seal the exhaust port 111. This prevents the high-pressure gas from flowing back from the exhaust port 111 into the compression chamber 220, effectively solving the problem of high operating noise caused by the high-pressure gas flow when the compressor 200 operates under under-compression conditions. It also prevents the compressor 200 from reversing due to the high-pressure gas flow when it stops, reducing the high and low pressure balancing time and improving the reliability of the compressor 200.

[0071] Because a limiting element 130 is provided on the side of the check valve column 120 away from the exhaust port 111, when the compressor 200 discharges, the high-pressure gas impacts the check valve column 120, causing the check valve column 120 to move away from the exhaust port 111. When the exhaust port 111 is opened, the check valve column 120 can abut against the limiting element 130 to limit the movement distance of the check valve column 120 in the exhaust groove 112, preventing the check valve column 120 from coming out, and avoiding jamming or wear of the check valve column 120 during the process of rising or falling under the impact of high-pressure gas. This ensures that when the compressor 200 is running under under-compression conditions or when the compressor 200 stops, the check valve column 120 can fall back smoothly to cover the exhaust port 111.

[0072] Furthermore, since a limiting element 130 is provided on the side of the check valve column 120 away from the exhaust port 111, the problem of the check valve column 120 falling off during the installation of the compressor 200 can be avoided, which helps to reduce the installation difficulty of the compressor 200 and improve the installation efficiency of the compressor 200.

[0073] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, optionally, the limiting member 130 is provided with a return air hole 131, one end of the return air hole 131 is connected to the exhaust groove 112, and the other end of the return air hole 131 passes through the limiting member 130.

[0074] In this embodiment, the limiting member 130 is provided with a return air hole 131. Specifically, one end of the return air hole 131 is connected to the exhaust groove 112, and the other end passes through the limiting member 130. It can be understood that the other end of the return air hole 131 is connected to the exhaust chamber.

[0075] Specifically, when the compressor 200 discharges gas, the high-pressure gas impacts the check valve column 120, causing the check valve column 120 to move away from the exhaust port 111, thereby opening the exhaust port 111. The high-pressure gas is then discharged through the exhaust port 111, the exhaust groove 112, the exhaust passage 121, and the return air hole 131.

[0076] When the compressor 200 operates under under-compression conditions or when the compressor 200 stops, the high-pressure gas flows back through the return gas hole 131 on the limiting member 130, impacting the check valve column 120 to move towards the side closer to the exhaust port 111, thereby sealing the exhaust port 111. This prevents the high-pressure gas from flowing back from the exhaust port 111 into the compression chamber 220, reduces the operating noise of the compressor 200, prevents the compressor 200 from reversing when it stops, and improves the reliability of the compressor 200.

[0077] like Figure 2As shown, in some embodiments, optionally, along the radial direction of the stationary vortex disk 110, the distance between the wall of the return air hole 131 and the wall of the exhaust groove 112 is less than or equal to the distance between the side wall of the exhaust passage 121 away from the central axis of the stationary vortex disk 110 and the wall of the exhaust groove 112.

[0078] In this embodiment, the distance between the wall of the return air hole 131 and the wall of the exhaust groove 112 in the radial direction of the stationary volute 110 is d1, and the distance between the side wall of the exhaust passage 121 away from the central axis of the stationary volute 110 and the wall of the exhaust groove 112 in the radial direction of the stationary volute 110 is d2. Wherein, d1 is less than or equal to d2. That is to say, in the axial direction of the stationary volute 110, the limiting member 130 will not obstruct the exhaust passage 121 on the check valve column 120, so that while limiting the check valve column 120, the exhaust of the compressor 200 is not affected, thus ensuring the efficiency of the compressor 200.

[0079] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the wall of the exhaust groove 112 is provided with a mounting groove 113, and a portion of the limiting member 130 is embedded in the mounting groove 113.

[0080] In this embodiment, the wall of the exhaust groove 112 is provided with a mounting groove 113. Specifically, a portion of the limiting member 130 is embedded in the mounting groove 113, thereby achieving assembly between the limiting member 130 and the stationary scroll 110. Moreover, the structure is simple, which helps to reduce installation difficulty and improve the overall installation efficiency of the compressor 200.

[0081] In some embodiments, the mounting groove 113 is optionally configured as an annular groove.

[0082] In this embodiment, the mounting groove 113 is defined as an annular groove. Since part of the limiting member 130 is embedded in the annular groove, the contact area between the limiting member 130 and the stationary scroll 110 is increased, thereby improving the connection strength between the limiting member 130 and the stationary scroll 110. This prevents the check valve column 120 from moving away from the exhaust port 111 under the impact of high-pressure gas when the compressor 200 is discharging, so that when it comes into contact with the limiting member 130, the limiting member 130 will disengage from the stationary scroll 110. This helps to improve the installation reliability of the limiting member 130.

[0083] like Figure 6 As shown, in some embodiments, optionally, along the circumference of the check valve stem 120, the limiting member 130 includes a first end 132 and a second end 133, with a gap between the first end 132 and the second end 133.

[0084] In this embodiment, since the limiting member 130 includes a first end 132 and a second end 133 with a certain distance between them in the circumferential direction of the check valve column 120, that is, the limiting member 130 has an opening and the opening passes through the limiting member 130, it can limit the check valve column 120 while making the limiting member 130 have a certain elasticity, which helps to reduce the installation difficulty of the limiting member 130 and further improve the installation efficiency of the compressor 200.

[0085] like Figure 6 As shown, in some embodiments, optionally, the limiting member 130 further includes a body 134, a first mounting portion 135 and a second mounting portion 136. Along the circumference of the check valve column 120, the first mounting portion 135 and the second mounting portion 136 are respectively disposed at both ends of the body 134. The first mounting portion 135 includes a first end 132 and the second mounting portion 136 includes a second end 133. The first mounting portion 135 is provided with a first mounting hole 137 and the second mounting portion 136 is provided with a second mounting hole 138.

[0086] In this embodiment, the limiting member 130 further includes a body 134, a first mounting portion 135, and a second mounting portion 136. Specifically, the first mounting portion 135 and the second mounting portion 136 are respectively disposed at both ends of the body 134 in the circumferential direction. The first mounting portion 135 includes a first end 132, and the second mounting portion 136 includes a second end 133. That is, there is a gap between the first mounting portion 135 and the second mounting portion 136 along the circumferential direction of the check valve column 120 to form an opening.

[0087] Since the first mounting part 135 is provided with a first mounting hole 137 and the second mounting part 136 is provided with a second mounting hole 138, during installation, an auxiliary tool is inserted into the first mounting hole 137 and the second mounting hole 138 respectively, and the width of the opening is reduced. Then, by embedding part of the body 134 into the mounting groove 113, the auxiliary tool is removed from the first mounting hole 137 and the second mounting hole 138. The limiting member 130 with a certain elasticity quickly rebounds and is locked into the mounting groove 113, thereby realizing the rapid installation of the limiting member 130, which is beneficial to improving the installation efficiency of the compressor 200.

[0088] In some embodiments, the limiting member 130 may optionally include an elastic member.

[0089] In this embodiment, since the limiting member 130 is an elastic member, that is, the limiting member 130 has a certain elasticity, the machining accuracy requirements of the mounting groove 113 can be reduced while ensuring reliable assembly between the limiting member 130 and the stationary scroll 110, thereby reducing the production cost of the compressor 200.

[0090] Furthermore, since the check valve 120 can abut against the limiting member 130 when the check valve 120 opens the exhaust port 111, thus limiting the check valve 120, by setting the limiting member 130 as an elastic member, the wear between the check valve 120 and the limiting member 130 can be reduced during the repeated movement of the check valve 120, which is beneficial to extending the service life of the check valve 120.

[0091] In some embodiments, the elastic element may optionally include a retaining ring.

[0092] In this embodiment, since the elastic element is a retaining ring, that is, the limiting element 130 is a retaining ring, it is beneficial to further reduce the installation difficulty of the compressor 200 and improve the assembly efficiency of the whole machine. Moreover, setting the limiting element 130 as a retaining ring not only ensures reliable assembly between the limiting element 130 and the stationary scroll, but also helps to reduce the production cost of the compressor 200.

[0093] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the static vortex disk 110 includes a disk body 114 and a valve seat 115, wherein the disk body 114 is provided with an exhaust port 111, the valve seat 115 is provided on the disk body 114, the valve seat 115 is provided with an exhaust groove 112, and the limiting member 130 is connected to the valve seat 115.

[0094] In this embodiment, the stationary volute 110 is defined as including a disc body 114 and a valve seat 115. Specifically, the disc body 114 is provided with an exhaust port 111, that is, the disc body 114 and the moving volute 210 form a compression chamber 220.

[0095] The limiting member 130 is connected to the valve seat 115. When the compressor 200 discharges, the high-pressure gas impacts the check valve column 120, causing the check valve column 120 to move away from the exhaust port 111. When the exhaust port 111 is opened, the check valve column 120 can abut against the limiting member 130 to limit the movement of the check valve column 120 in the exhaust groove 112. This prevents the check valve column 120 from getting stuck or worn during the process of rising or falling under the impact of high-pressure gas. It ensures that when the compressor 200 is running under under-compression conditions or when the compressor 200 stops, the check valve column 120 can fall back smoothly to cover the exhaust port 111.

[0096] Optionally, the valve seat 115 and the disc body 114 are an integral structure, that is, the valve seat 115 is integrated on the disc body 114, which can improve the installation and movement space of the return valve column 120, while reducing the number of parts, thereby reducing the production cost of the compressor 200.

[0097] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the check valve column 120 includes an outer sidewall 122 extending axially along the stationary volute 110, the outer sidewall 122 being clearance-fitted with the groove wall of the exhaust groove 112.

[0098] In this embodiment, since the outer wall 122 of the check valve column 120 is fitted with the groove wall of the exhaust groove 112, that is, there is a small gap between the outer wall 122 of the check valve column 120 and the groove wall of the exhaust groove 112, it can be ensured that the check valve column 120 can move up and down smoothly in the exhaust groove 112 to open or seal the exhaust port 111. In addition, it can also ensure the perpendicularity of the back of the check valve column 120 and the stationary vortex plate 110, further preventing the check valve column 120 from getting stuck or worn during the process of rising or falling under the impact of high pressure gas.

[0099] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, a return air groove 123 is provided on the side of the check valve column 120 away from the exhaust port 111. The return air groove 123 communicates with the exhaust groove 112. Along the radial direction of the check valve column 120, the return air groove 123 is located inside the exhaust channel 121.

[0100] In this embodiment, since a return gas groove 123 is provided on the side of the check valve column 120 away from the exhaust port 111, and the return gas groove 123 is connected to the exhaust groove 112, when the compressor 200 is running under under-compression conditions or when the compressor 200 stops, the high-pressure gas flows back and impacts the check valve column 120 to move towards the side closer to the exhaust port 111 to cover the exhaust port 111. This increases the contact area between the high-pressure gas and the check valve column 120, allowing the check valve column 120 to move quickly towards the side where the exhaust port 111 is located. This further prevents the high-pressure gas from flowing back from the exhaust port 111 into the compression chamber 220 when the compressor 200 is running under under-compression conditions or when the compressor 200 stops.

[0101] like Figure 5 As shown, in some embodiments, optionally, there are multiple exhaust channels 121, which are arranged at intervals along the circumference of the check valve column 120 and are respectively connected to the exhaust groove 112.

[0102] In this embodiment, the number of exhaust channels 121 is limited to multiple. Specifically, multiple exhaust channels 121 are arranged at intervals along the circumference of the check valve column 120, and multiple exhaust channels 121 are respectively connected to the exhaust groove 112. When the compressor 200 exhausts, the high-pressure gas impacts the check valve column 120, causing the check valve column 120 to move away from the exhaust port 111, so as to open the exhaust port 111. The high-pressure gas is discharged through the exhaust port 111, the exhaust groove 112 and the multiple exhaust channels 121 respectively, which helps to ensure the efficiency of the compressor 200 when exhausting.

[0103] like Figure 5 As shown, in some embodiments, optionally, along the radial direction of the check valve stem 120, the exhaust passage 121 includes opposing first wall surfaces 124 and second wall surfaces 125, at least one of the first wall surfaces 124 and second wall surfaces 125 being configured as an arcuate surface.

[0104] In this embodiment, the exhaust passage 121 is defined as including a first wall surface 124 and a second wall surface 125. Specifically, the first wall surface 124 and the second wall surface 125 are arranged opposite each other in the radial direction of the check valve column 120. Optionally, the first wall surface 124 is close to the central axis of the stationary scroll plate 110, and the second wall surface 125 is away from the central axis of the stationary scroll plate 110. Alternatively, the first wall surface 124 is away from the central axis of the stationary scroll plate 110, and the second wall surface 125 is close to the central axis of the stationary scroll plate 110.

[0105] Since at least one of the first wall surface 124 and the second wall surface 125 is an arc-shaped surface, the flow cross-sectional area of ​​the exhaust passage 121 can be increased, ensuring the efficiency of the compressor 200 during exhaust and improving the stability and reliability of the compressor 200 during operation.

[0106] Optionally, the cross-sectional shape of the exhaust passage 121 is an oblong hole.

[0107] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in one specific embodiment, optionally, the fixed scroll plate (static scroll plate assembly 100) with exhaust check valve function includes a valve stem (check valve stem 120), an exhaust check valve mounting structure (valve seat 115) provided on the fixed scroll plate, and a retaining ring (limiting member 130) for mounting the exhaust check valve.

[0108] The exhaust check valve mounting structure (valve seat 115) on the fixed scroll plate (stationary scroll plate 110) cooperates with the exhaust check valve rod (check valve rod 120) so that the exhaust valve rod (check valve rod 120) can move upward along the exhaust check valve mounting structure (valve seat 115) to open the exhaust port 111 or move downward to close the exhaust port 111. At the same time, it can ensure the perpendicularity of the exhaust check valve rod (check valve rod 120) to the back of the fixed scroll plate (stationary scroll plate 110) and prevent the exhaust check valve rod (check valve rod 120) from getting stuck or wearing when opening or closing the exhaust port 111. The exhaust check valve mounting structure (valve seat 115) of the fixed scroll plate (stationary scroll plate 110) is provided with a snap ring groove (mounting groove 113) so that the snap ring (limiting member 130) is fixed on the fixed scroll plate (stationary scroll plate 110) to limit the upward movement of the exhaust check valve column (check valve column 120) and prevent the exhaust check valve column (check valve column 120) from coming out when it opens.

[0109] According to a second aspect of the present invention, a compressor 200 is provided, including a static scroll assembly 100 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the static scroll assembly 100, which will not be repeated here.

[0110] like Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the compressor 200 further includes a moving scroll 210, which forms a compression chamber 220 with the stationary scroll 110, and the compression chamber 220 is connected to the exhaust port 111.

[0111] The stationary scroll 110 and the moving scroll 210 form a compression chamber 220, which is connected to the exhaust port 111. Specifically, during the operation of the compressor 200, the moving scroll 210 rotates relative to the stationary scroll 110 to compress the gas in the compression chamber 220. When the gas pressure in the compression chamber 220 reaches the exhaust pressure, the compressed high-temperature and high-pressure gas is discharged from the exhaust port 111 to the exhaust chamber (i.e., the high-pressure chamber), and finally discharged from the exhaust chamber to the outside of the compressor 200 housing.

[0112] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in one specific embodiment, optionally, the scroll compressor (compressor 200) includes a housing and a compression assembly installed within the housing. The compression assembly includes a main frame, a stationary scroll plate (stationary scroll plate 110), a moving scroll plate (moving scroll plate 210), a crankshaft, a motor, and a secondary frame. The main frame is fixed to the upper part within the housing, and the stationary scroll plate (stationary scroll plate 110) and the moving scroll plate (moving scroll plate 210) are mounted on top of it. The pump body portion formed by the combination of the stationary scroll plate (stationary scroll plate 110) and the moving scroll plate (moving scroll plate 210) constitutes the scroll compression chamber (compression chamber 220).

[0113] The exhaust check valve mounting structure (valve seat 115) on the fixed scroll plate (stationary scroll plate 110) cooperates with the exhaust check valve rod (check valve rod 120) so that the exhaust valve rod (check valve rod 120) can move upward along the exhaust check valve mounting structure (valve seat 115) to open the exhaust port 111 or move downward to close the exhaust port 111. At the same time, it can ensure the perpendicularity of the exhaust check valve rod (check valve rod 120) to the back of the fixed scroll plate (stationary scroll plate 110) and prevent the exhaust check valve rod (check valve rod 120) from getting stuck or wearing when opening or closing the exhaust port 111.

[0114] The exhaust check valve mounting structure (valve seat 115) of the fixed scroll plate (stationary scroll plate 110) is provided with a snap ring groove (mounting groove 113) so that the snap ring (limiting member 130) is fixed on the fixed scroll plate (stationary scroll plate 110) to limit the upward movement of the exhaust check valve column (check valve column 120) and prevent the exhaust check valve column (check valve column 120) from coming out when it opens.

[0115] like Figure 2 As shown, the exhaust valve stem (check valve stem 120) can move upward along the exhaust check valve mounting structure (valve seat 115). The retaining ring (limiting member 130) will restrict the upward movement of the exhaust valve stem (check valve stem 120) to prevent the exhaust valve stem (check valve stem 120) from falling out. At this time, the exhaust port 111 is open, and normal exhaust is performed.

[0116] The scroll compressor (compressor 200) adopts the aforementioned fixed scroll plate (stationary scroll plate assembly 100) with exhaust check valve function. This utility model has the advantages of simple structure and low cost, and solves the problems of high shutdown noise, refrigerant backflow causing compressor reversal during shutdown, long high and low pressure balancing time, and poor reliability of scroll compressors in related technologies.

[0117] According to a third aspect of the present invention, a refrigeration device is provided, including a static scroll assembly 100 or a compressor 200 as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the static scroll assembly 100 or the compressor 200, which will not be repeated here.
