Description

Technical Field

[0001] This utility model relates to the field of compressors, specifically, it designs a scroll assembly, a compressor, and a refrigeration device. Background Technology

[0002] Currently, in related technologies, compressors include a stationary disc and a moving disc, which work together to compress the refrigerant. A back pressure plate is located on the side of the stationary disc furthest from the moving disc. The back pressure plate, in conjunction with the stationary disc, separates the exhaust chamber and the bypass chamber. However, when the pressure difference between the exhaust chamber and the bypass chamber is large, the refrigerant will flow through the gap between the back pressure plate and the stationary disc from the high-pressure chamber to the low-pressure chamber, thereby reducing the compressor's efficiency. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this utility model proposes a vortex assembly.

[0005] The second aspect of this utility model provides a compressor.

[0006] The third aspect of this utility model proposes a refrigeration device.

[0007] In view of this, the first aspect of the present invention provides a vortex assembly, including a stationary disc, a back pressure plate, and a sealing gasket. The stationary disc includes a first disc body and a first vortex blade, the first vortex blade being disposed on the first disc body. The back pressure plate is located on the side of the first disc body away from the first vortex blade, and the back pressure plate and the first disc body enclose an exhaust chamber and a bypass chamber. The sealing gasket is disposed between the back pressure plate and the first disc body and is arranged around the exhaust chamber to separate the exhaust chamber and the bypass chamber.

[0008] This application provides a scroll assembly including a stationary disc, a back pressure plate, and a sealing gasket. The stationary disc has a first disc body and first scroll blades, the first scroll blades being disposed on the first disc body to cooperate with a moving disc. The back pressure plate is disposed on the side of the first disc body away from the first scroll blades, serving to separate the various pressure chambers located on the first disc body, facilitating the application of pressure from the back pressure chambers to the stationary disc, thereby achieving an axial seal between the moving and stationary discs. An exhaust chamber and a bypass chamber are formed between the back pressure plate and the first disc body. Compressed gas enters the exhaust chamber, where the pressure is the exhaust pressure, allowing the gas to be discharged. A bypass hole is provided on the back of the stationary disc, connecting the bypass chamber to the bypass chamber via a one-way valve, enabling the compressor to function as a variable-capacity unit. When the compressor is at full load, the pressure in the bypass hole is the intermediate pressure; when the compressor is at half load, the pressure in the bypass hole is the suction pressure, thus allowing the variable-capacity compressor to switch between full-load and half-load functions. By placing the sealing gasket between the back pressure plate and the first disc, and arranging it around the exhaust chamber, the exhaust chamber and the bypass chamber can be separated, making them independent and not interconnected. The back pressure plate and the first disc compress the sealing gasket, allowing it to adhere to their surfaces. When the back pressure plate and the first disc work together, the sealing gasket can prevent refrigerant from flowing from the high-pressure chamber to the low-pressure chamber through the gap between the back pressure plate and the stationary disc, even when there is a large pressure difference between the exhaust chamber and the bypass chamber. This achieves a sealing function, preventing pressure leakage in the relevant chambers and ensuring the normal operation of the scroll assembly.

[0009] This technical solution provides a vortex assembly, in which a sealing gasket is provided with a first through hole; the vortex assembly also includes a connector, which passes through the back pressure plate and the first through hole and is connected to the first disc body.

[0010] In this technical solution, the sealing gasket has a first through hole, providing installation space for the connector. The connector can pass through the back pressure plate and the first through hole to connect and lock with the first disc. Furthermore, when the back pressure plate and the first disc compress the sealing gasket, it can be fixed in the installation position, preventing movement. Therefore, when the back pressure plate and the first disc work together, the sealing gasket can achieve its sealing function. By providing the first through hole on the sealing gasket, the connector is prevented from being exposed, ensuring that the connector is surrounded by the sealing gasket. This reduces the probability of the first through hole connecting to the exhaust chamber or the bypass chamber, thus improving the sealing effect.

[0011] In some technical solutions of this application, optionally, the sealing gasket includes a gasket and a first rib. The gasket is disposed between the back pressure plate and the first disc body. The first rib protrudes from the surface of the gasket and is arranged around the exhaust cavity. The first rib contacts the back pressure plate and the first disc body on both sides of the vortex assembly in the axial direction.

[0012] In this technical solution, the sealing gasket also includes a gasket and a first rib. The gasket is disposed between the back pressure plate and the first disc body, providing a seal for the space formed between the back pressure plate and the first disc body. The first rib protrudes from the surface of the gasket to ensure the sealing performance of the sealing gasket. Arranging the first rib around the exhaust chamber allows the gas in the exhaust chamber to be kept within the exhaust chamber, while simultaneously separating the exhaust chamber and the bypass chamber. The first rib contacts the back pressure plate and the first disc body on both sides along the axial direction of the vortex assembly, respectively. Because the first rib protrudes from the surface of the gasket, when the back pressure plate and the first disc body move towards each other and compress the sealing gasket, the first rib will deform and come into close contact with the back pressure plate and the first disc body. At this time, the force between the first rib and the back pressure plate and the first disc body increases, increasing the resistance to gas penetration through the sealing gasket. By providing the first rib on the sealing gasket, the sealing effect is further improved.

[0013] In some technical solutions of this application, the sealing gasket may optionally include a second rib, which protrudes from the surface of the gasket and is arranged around the first through hole.

[0014] In this technical solution, the sealing gasket also includes a second rib. The second rib protrudes from the surface of the gasket and is arranged around the first through hole. The second rib can wrap around the connector installed in the first through hole in the circumferential direction, isolating the inside of the first through hole from the outside of the first through hole, and absorbing most of the compressive force of the connector on the sealing gasket. This reduces the deformation of the sealing gasket around the first through hole caused by the force. By setting the second rib around the first through hole on the sealing gasket, the sealing gasket avoids the risk of deformation of the first rib due to the compressive force of the connector, which could lead to communication between the exhaust chamber and the bypass chamber, thus further improving the sealing effect.

[0015] Optionally, in some technical solutions of this application, the vortex assembly further includes a float assembly, which is disposed on the side of the back pressure plate away from the first disc body, and a back pressure cavity is provided between the float assembly and the back pressure plate; a back pressure hole is provided on the first disc body; a second through hole is provided on the gasket, which is located between the first rib and the second rib, and the back pressure hole communicates with the back pressure cavity through the second through hole.

[0016] In this technical solution, the vortex assembly also includes a float assembly, which is positioned on the side of the back pressure plate away from the first disc, with the back pressure plate located between the float assembly and the first disc. A back pressure cavity exists between the float assembly and the back pressure plate. The relative position between the float assembly and the back pressure plate is adjusted according to pressure changes within the back pressure cavity. The back pressure cavity applies pressure from the stationary disc to the moving disc on the first disc, causing the stationary disc and the moving disc to engage, thereby increasing the sealing between them. A back pressure hole is provided on the first disc to provide a flow channel for gas. Partially compressed gas can enter the back pressure cavity through the back pressure hole. A second through hole is provided on the gasket, located between the first and second ribs, to separate the second through hole from the exhaust cavity and the bypass cavity. The back pressure hole communicates with the back pressure cavity through the second through hole, ensuring that gas entering and exiting the back pressure cavity through the second through hole does not penetrate the first and second ribs and leak, thus satisfying the sealing requirements between the three cavities: the back pressure cavity, the exhaust cavity, and the bypass cavity. By placing the second through hole between the first and second ribs, the pressure in the back pressure chamber can be kept stable, thereby allowing the back pressure chamber to continuously apply force to the first disc, enhancing the axial seal between the moving and stationary discs, improving the sealing performance of the scroll assembly, and increasing the compression efficiency.

[0017] Optionally, in some technical solutions of this application, the sealing gasket may further include a third rib, which protrudes from the surface of the gasket, one end of the third rib is connected to the first rib, and the other end is connected to the second rib, and the third rib is located between the second through hole and the first through hole.

[0018] In this technical solution, the sealing gasket also has a third rib. The third rib protrudes from the surface of the gasket and is used to form a tight seal with the back pressure plate. One end of the third rib is connected to the first rib, and the other end is connected to the second rib, allowing the third rib to achieve a sealing function around a portion of the second through hole's circumference. Positioning the third rib between the second and first through holes separates them, ensuring that gas entering or leaving the back pressure chamber through the second through hole does not penetrate the third rib, thus preventing pressure leakage caused by the connection between the second and first through holes. By using the third rib on the sealing gasket, a non-communicating and relatively independent sealing space is formed between the first and second through holes, improving the sealing effect between them.

[0019] Furthermore, the first rib is connected to the second rib, and the two ends of the third rib are connected to the first rib and the second rib, respectively.

[0020] Optionally, in some technical solutions of this application, the stationary disk may further include a mounting section, which is located on the side of the first disk body away from the first vortex blade and arranged circumferentially along the first disk body; the back pressure plate and the float plate assembly are located inside the mounting section, and the back pressure plate, the float plate assembly and the mounting section enclose a back pressure cavity.

[0021] In this technical solution, the stationary disc also includes a mounting section. The mounting section can cooperate with the back pressure plate and float plate assembly. The mounting section is positioned on the side of the first disc body away from the first vortex blade and is arranged circumferentially along the first disc body, so that the first disc body and the mounting section form an internally hollow mounting space, allowing other components to be placed within this space. The back pressure plate and float plate assembly are placed within the mounting space of the mounting section, with a sealed connection between the mounting section and both the back pressure plate and float plate assembly. In this case, a back pressure cavity is formed within the space enclosed by the back pressure plate, float plate assembly, and mounting section to accommodate gas entry and withstand the pressure generated after the gas enters the back pressure cavity.

[0022] Furthermore, when the pressure inside the back pressure chamber increases, the float assembly moves away from the back pressure plate; when the pressure inside the back pressure chamber decreases, the float assembly moves closer to the back pressure plate.

[0023] Specifically, the pressures within the exhaust chamber, bypass chamber, and back pressure chamber are all different, so that the compressor can perform variable-volume compression of the gas.

[0024] In some technical solutions of this application, optionally, the number of first through holes is multiple; the sealing gasket is projected along the axis of the vortex assembly to obtain a first projection surface, the projection of the axis of the vortex assembly on the first projection surface is a first point, the projection of the axes of the multiple first through holes on the first projection surface is multiple second points, and at least two of the multiple second points are not equidistant from the first point.

[0025] In this technical solution, the sealing gasket has multiple first through holes. A first projection surface is obtained by projecting the sealing gasket along the axis of the vortex assembly. This first projection surface is parallel to the upper surface of the first disc. The projection of the vortex assembly's axis onto the first projection surface is designated as a first point, and the projections of the axes of the multiple first through holes onto the first projection surface are designated as multiple second points. At least two of the multiple second points are not equidistant from the first point. In other words, the multiple first through holes are asymmetrically distributed around the exhaust chamber on the sealing gasket. By arranging the multiple first through holes asymmetrically on the sealing gasket, the sealing gasket can avoid obstructing the back pressure hole and bypass hole during installation, preventing the sealing gasket from covering or encroaching on these holes and thus affecting their normal function.

[0026] Optionally, in some technical solutions of this application, a bypass hole is provided on the first disc body, and the bypass hole communicates with the bypass cavity; the sealing gasket is located on the side of the bypass hole near the axis of the vortex assembly.

[0027] In this technical solution, a bypass hole is provided on the first disc to provide a flow channel for gas. The bypass hole communicates with the bypass cavity, allowing gas to enter the first vortex blade from the bypass cavity through the bypass hole, where it is compressed by the vortex assembly. Placing the sealing gasket on the side of the bypass hole near the axis of the vortex assembly allows the sealing gasket to avoid the position of the bypass hole, while also reserving space for the bypass cavity to be formed.

[0028] Furthermore, the bypass port and the bypass chamber are connected by a one-way valve. When the compressor is under full load, the pressure in the bypass is not lower than the pressure in the bypass port, and the gas cannot enter the bypass chamber through the bypass port. When the compressor is under half load, the pressure in the bypass chamber is the suction pressure, and the gas in the compression chamber enters the bypass chamber through the bypass.

[0029] In some technical solutions of this application, optionally, the sealing gasket is projected along the axis of the compressor to obtain a first projection surface, the axis of the vortex assembly is projected onto the first projection surface as a first point, the axis of the first through hole is projected onto the first projection surface as a second point, the axis of the bypass hole is projected onto the first projection surface as a third point, and the distance between the third point and the first point is less than the distance between the second point and the first point.

[0030] In this technical solution, the sealing gasket is projected along the compressor axis to obtain a first projection surface, which is parallel to the upper surface of the first disc. The projection of the axis of the scroll assembly onto the first projection surface is set as a first point, the projection of the axis of the first through hole onto the first projection surface is set as a second point, and the projection of the axis of the bypass hole onto the first projection surface is set as a third point. The distance between the third point and the first point is less than the distance between the second point and the first point, so that a portion of the sealing gasket always provides clearance space for the bypass hole, thereby ensuring that space can be further reserved for the formation of the bypass cavity and avoiding encroachment on the formation space of the bypass cavity. By improving the structure of the sealing gasket and the layout of the screw holes, the formation space of the bypass cavity can be satisfied, while ensuring the sealing effect of the exhaust cavity, back pressure cavity and bypass cavity.

[0031] In some technical solutions of this application, optionally, the width of the narrowest part of the sealing gasket is greater than or equal to 3.5 mm.

[0032] In this technical solution, by setting the width of the sealing gasket to be greater than or equal to 3.5 mm at the narrowest point, the sealing gasket can ensure a good sealing effect even at the narrowest point, thus enabling the functions of the back pressure chamber and the bypass chamber to be realized.

[0033] Optionally, in some technical solutions of this application, the vortex assembly further includes a moving disk, which includes a second disk body and a second vortex blade. The second vortex blade is connected to the second disk body and cooperates with the first vortex blade. The first vortex blade and the second vortex blade enclose a plurality of compression cavities.

[0034] In this technical solution, the vortex assembly also includes a moving disk, which includes a second disk body and a second vortex blade. The second vortex blade is connected to the second disk body. When the second disk body rotates, the second vortex blade also rotates, and the second vortex blade can mesh with the first vortex blade. At the same time, the second vortex blade can rotate relative to the first vortex blade. Through the mutual cooperation between the stationary disk and the moving disk, multiple compression chambers can be formed between the first vortex blade and the second vortex blade to compress the gas.

[0035] Specifically, the compression chamber is crescent-shaped. As the compressor runs, the volume of the crescent-shaped compression chamber gradually decreases, thereby achieving the function of compressing the gas inside the crescent-shaped compression chamber.

[0036] The second aspect of this technical solution provides a compressor including a scroll assembly as described in any of the above-described technical solutions. Since the compressor includes the scroll assembly of any of the above-described technical solutions, it possesses all the beneficial effects of the scroll assembly of any of the above-described technical solutions, which will not be elaborated further here.

[0037] Specifically, the compressor in this technical solution is a compressor.

[0038] The third aspect of this technical solution provides a refrigeration device, including the scroll assembly of any of the above-described technical solutions or the compressor of the second aspect. Since this refrigeration device includes the scroll assembly of any of the above-described technical solutions or the compressor of the second aspect, it possesses all the beneficial effects of the scroll assembly of any of the above-described technical solutions or the compressor of the second aspect, which will not be elaborated further here. Specifically, the refrigeration device in this technical solution is a refrigerator, air conditioner, freezer, wine cabinet, or refrigerated display case, etc.

Detailed Implementation

[0047] 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.

[0048] 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.

[0049] The following reference Figures 1 to 4 This invention describes a scroll assembly, a compressor, and a refrigeration device according to some embodiments of the present invention.

[0050] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, a vortex assembly 100 is provided, including a stationary disc 110, a back pressure plate 130, and a sealing gasket 140. The stationary disc 110 includes a first disc body 112 and a first vortex blade 118, with the first vortex blade 118 disposed on the first disc body 112. The back pressure plate 130 is located on the side of the first disc body 112 away from the first vortex blade 118, and the back pressure plate 130 and the first disc body 112 enclose an exhaust chamber 134 and a bypass chamber 136. The sealing gasket 140 is disposed between the back pressure plate 130 and the first disc body 112 and is arranged around the exhaust chamber 134 to separate the exhaust chamber 134 and the bypass chamber 136.

[0051] The vortex assembly 100 provided in this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a stationary disc 110, a back pressure plate 130, and a sealing gasket 140. The stationary disc 110 is provided with a first disc body 112 and a first vortex blade 118. The first vortex blade 118 is disposed on the first disc body 112 to cooperate with the moving disc 180. The back pressure plate 130 is disposed on the side of the first disc body 112 away from the first vortex blade 118, serving to separate the various pressure chambers located on the first disc body 112, facilitating the application of pressure from the back pressure chamber 132 to the stationary disc 110, thereby achieving an axial seal between the moving disc and the stationary disc 110. An exhaust chamber 134 and a bypass chamber 136 are formed between the back pressure plate 130 and the first disc body 112. Compressed gas enters the exhaust chamber 134, where the pressure is the exhaust pressure, allowing the gas to be discharged. A bypass hole 116 is provided on the back of the stationary plate 110, allowing the compression chamber 186 to bypass the chamber 136 via a one-way valve, thus enabling the variable volume function of the compressor 200. When the compressor 200 is under full load, the pressure in the bypass hole 116 is the intermediate pressure; when the compressor 200 is under half load, the pressure in the bypass hole 116 is the suction pressure, thereby allowing the variable capacity compressor 200 to switch between full load and half load functions. A sealing gasket 140 is placed between the back pressure plate 130 and the first plate 112, and arranged around the exhaust chamber 134, separating the exhaust chamber 134 from the bypass chamber 136, ensuring that the exhaust chamber 134 and the bypass chamber 136 are not interconnected and are independent of each other. When the back pressure plate 130 and the first disc 112 compress the sealing gasket 140, the sealing gasket 140 can adhere to the surfaces of the back pressure plate 130 and the first disc 112. Thus, when the back pressure plate 130 and the first disc 112 work together, the sealing gasket 140 can achieve a sealing function to prevent pressure leakage in the relevant cavities, thereby ensuring the normal operation of the vortex assembly 100.

[0052] Furthermore, the connector 160 is a screw, and the screw is threadedly connected to the first through hole 142.

[0053] Specifically, such as Figure 1 As shown, the side of the first disk 112 away from the first vortex blade 118 is A.

[0054] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0055] like Figure 2 and Figure 3 As shown, the sealing gasket 140 is provided with a first through hole 142; the vortex assembly 100 also includes a connector 160, which passes through the back pressure plate 130 and the first through hole 142 and is connected to the first disc body 112.

[0056] In this embodiment, such as Figure 2 and Figure 3 As shown, the sealing gasket 140 has a first through hole 142, providing installation space for the connector 160. This allows the connector 160 to pass through the back pressure plate 130 and the first through hole 142, connecting and locking with the first disc 112. Furthermore, when the back pressure plate 130 and the first disc 112 compress the sealing gasket 140, it keeps the sealing gasket 140 in place, preventing movement. Thus, when the back pressure plate 130 and the first disc 112 work together, the sealing gasket 140 achieves a sealing function. By providing the first through hole 142 on the sealing gasket 140, the connector 160 is prevented from being obstructed, ensuring that the connector 160 is surrounded by the sealing gasket 140. This reduces the probability of the first through hole 142 connecting to the exhaust chamber 134 or the bypass chamber 136, improving the sealing effect.

[0057] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0058] like Figure 2 and Figure 3 As shown, the sealing gasket 140 includes a gasket 144 and a first rib 148. The gasket 144 is disposed between the back pressure plate 130 and the first disc 112. The first rib 148 protrudes from the surface of the gasket 144 and is arranged around the exhaust chamber 134. The first rib 148 contacts the back pressure plate 130 and the first disc 112 on both sides of the vortex assembly 100 in the axial direction.

[0059] In this embodiment, such as Figure 2 and Figure 3As shown, the sealing gasket 140 also includes a gasket 144 and a first rib 148. The gasket 144 is disposed between the back pressure plate 130 and the first disc 112 to provide a seal for the space formed between the back pressure plate 130 and the first disc 112. The first rib 148 protrudes from the surface of the gasket 144 to ensure the sealing performance of the sealing gasket 140. Arranging the first rib 148 around the exhaust chamber 134 can keep the gas in the exhaust chamber 134 within the exhaust chamber 134, while also separating the exhaust chamber 134 from the bypass chamber 136. The first rib 148 contacts the back pressure plate 130 and the first disc 112 on both sides of the vortex assembly 100 along the axial direction. Since the first rib 148 protrudes from the surface of the gasket 144, when the back pressure plate 130 and the first disc 112 move towards each other and compress the sealing gasket 140, the first rib 148 deforms and comes into close contact with the back pressure plate 130 and the first disc 112. At this time, the force between the first rib 148 and the back pressure plate 130 and the first disc 112 increases, increasing the resistance to gas penetration of the sealing gasket 140. By providing the first rib 148 on the sealing gasket 140, the sealing effect is further improved.

[0060] Specifically, such as Figure 1 As shown, the axial direction of the vortex assembly 100 is direction D.

[0061] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0062] like Figure 2 and Figure 3 As shown, the sealing gasket 140 also includes a second rib 150, which protrudes from the surface of the gasket 144 and is arranged around the first through hole 142.

[0063] In this embodiment, such as Figure 2 and Figure 3 As shown, the sealing gasket 140 also includes a second rib 150. The second rib 150 protrudes from the surface of the gasket 144 and is arranged around the first through hole 142. The second rib 150 can wrap around the connector 160 installed in the first through hole 142, isolating the inside of the first through hole 142 from the outside of the first through hole 142, and absorbing most of the compressive force of the connector 160 on the sealing gasket 140. This reduces the deformation of the sealing gasket 140 around the first through hole 142 due to the force. By providing the second rib 150 around the first through hole 142 on the sealing gasket 140, the sealing gasket 140 avoids the risk of the first rib 148 deforming due to the compressive force of the connector 160, thereby allowing the exhaust chamber 134 to communicate with the bypass chamber 136, further improving the sealing effect.

[0064] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0065] like Figure 1 As shown, the vortex assembly 100 also includes a float assembly 170, which is disposed on the side of the back pressure plate 130 away from the first disc 112. A back pressure cavity 132 is provided between the float assembly 170 and the back pressure plate 130. A back pressure hole 114 is provided on the first disc 112. A second through hole 146 is provided on the gasket 144. The second through hole 146 is located between the first rib 148 and the second rib 150. The back pressure hole 114 communicates with the back pressure cavity 132 through the second through hole 146.

[0066] In this embodiment, such as Figure 1 As shown, the vortex assembly 100 also includes a float assembly 170, which is positioned on the side of the back pressure plate 130 away from the first disc 112, such that the back pressure plate 130 is located between the float assembly 170 and the first disc 112. A back pressure cavity 132 is provided between the float assembly 170 and the back pressure plate 130. The relative position between the float assembly 170 and the back pressure plate 130 is adjusted according to the pressure changes within the back pressure cavity 132. The back pressure cavity 132 applies pressure generated from the stationary disc 110 to the moving disc 180 onto the first disc 112, causing the stationary disc 110 and the moving disc 180 to engage, thereby increasing the sealing between the stationary disc 110 and the moving disc 180. A back pressure hole 114 is provided on the first disc 112 to provide a flow channel for gas. Partially compressed gas can enter through the back pressure hole 114. Inside the back pressure chamber 132, the gasket 144 is provided with a second through hole 146. The second through hole 146 is located between the first rib 148 and the second rib 150, so as to separate the second through hole 146 from the exhaust chamber 134 and the bypass chamber 136 respectively. The back pressure hole 114 communicates with the back pressure chamber 132 through the second through hole 146, ensuring that when the gas enters and exits the back pressure chamber 132 through the second through hole 146, it will not penetrate the first rib 148 and the second rib 150 and leak, thus satisfying the sealing requirements between the three chambers of the back pressure chamber 132, the exhaust chamber 134 and the bypass chamber 136. By placing the second through hole 146 between the first rib 148 and the second rib 150, the pressure in the back pressure cavity 132 can be kept stable, so that the back pressure cavity 132 can continuously apply force to the first disc 112, thereby enhancing the axial seal between the moving disc 180 and the stationary disc 110, improving the sealing performance of the scroll assembly 100, and increasing the compression efficiency.

[0067] Specifically, such as Figure 1 As shown, the side of the back pressure plate 130 away from the first disc 112 is B.

[0068] Specifically, such as Figure 1As shown, the direction from stationary disk 110 to moving disk 180 is direction H.

[0069] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0070] like Figure 2 and Figure 3 As shown, the sealing gasket 140 also includes a third rib 152, which protrudes from the surface of the gasket 144. One end of the third rib 152 is connected to the first rib 148, and the other end is connected to the second rib 150. The third rib 152 is located between the second through hole 146 and the first through hole 142.

[0071] In this embodiment, such as Figure 2 and Figure 3 As shown, the sealing gasket 140 is also provided with a third rib 152. The third rib 152 protrudes from the surface of the gasket 144 and is used to form a seal by tightly contacting the back pressure plate 130. One end of the third rib 152 is connected to the first rib 148 and the other end is connected to the second rib 150, so that the third rib 152 can achieve a sealing function around a portion of the circumference of the second through hole 146. The third rib 152 is placed between the second through hole 146 and the first through hole 142 to separate the second through hole 146 and the first through hole 142, so as to ensure that when the gas enters or exits the back pressure chamber 132 through the second through hole 146, it will not penetrate the third rib 152, thereby causing the second through hole 146 and the first through hole 142 to connect and cause air pressure leakage. By using the third rib 152 on the sealing gasket 140, a non-communicating and relatively independent sealing space is formed between the first through hole 142 and the second through hole 146, thereby improving the sealing effect between the first through hole 142 and the second through hole 146.

[0072] Furthermore, the first rib 148 is connected to the second rib 150, and the two ends of the third rib 152 are respectively connected to the first rib 148 and the second rib 150.

[0073] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0074] like Figure 1 and Figure 2 As shown, the stationary disk 110 also includes a mounting part 120, which is disposed on the side of the first disk body 112 away from the first vortex blade 118 and arranged circumferentially along the first disk body 112; the back pressure plate 130 and the float assembly 170 are disposed in the mounting part 120, and the back pressure plate 130, the float assembly 170 and the mounting part 120 surround the back pressure cavity 132.

[0075] In this embodiment, such as Figure 1 and Figure 2 As shown, the stationary disk 110 also includes a mounting portion 120. The mounting portion 120 can cooperate with the back pressure plate 130 and the float assembly 170. The mounting portion 120 is located on the side of the first disk body 112 away from the first vortex blade 118 and is arranged circumferentially along the first disk body 112, so that the first disk body 112 and the mounting portion 120 form an internally hollow mounting space, which can accommodate other components. The back pressure plate 130 and the float assembly 170 are placed in the mounting space within the mounting portion 120. The mounting portion 120 is sealed to the back pressure plate 130 and the float assembly 170. At this time, a back pressure cavity 132 is formed within the space enclosed by the back pressure plate 130, the float assembly 170, and the mounting portion 120 to accommodate gas and withstand the pressure generated after the gas enters the back pressure cavity 132.

[0076] Furthermore, when the pressure inside the back pressure chamber 132 increases, the float assembly 170 moves away from the back pressure plate 130; when the pressure inside the back pressure chamber 132 decreases, the float assembly 170 moves closer to the back pressure plate 130.

[0077] Specifically, the pressures inside the exhaust chamber 134, the bypass chamber 136, and the back pressure chamber 132 are all different, so that the compressor 200 can perform variable-volume compression of the gas.

[0078] Specifically, such as Figure 2 As shown, the circumferential direction of the first disk 112 is direction F.

[0079] Specifically, such as Figure 1 As shown, the direction away from the back pressure plate 130 is direction G.

[0080] Specifically, such as Figure 1 As shown, the direction closest to the back pressure plate 130 is direction E.

[0081] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0082] like Figure 2 and Figure 3 As shown, there are multiple first through holes 142; the sealing gasket 140 is projected along the axis of the compressor 200 scroll assembly 100 to obtain a first projection surface, the projection of the axis of the scroll assembly 100 on the first projection surface is a first point, the projection of the axes of the multiple first through holes 142 on the first projection surface is a multiple second point, and at least two of the multiple second points are not equidistant from the first point.

[0083] In this embodiment, such as Figure 2 and Figure 3As shown, the sealing gasket 140 is provided with a plurality of first through holes 142. A first projection surface is obtained by projecting the sealing gasket 140 along the axis of the compressor 200 scroll assembly 100. The first projection surface is parallel to the upper surface of the first disc 112. The projection of the axis of the scroll assembly 100 on the first projection surface is set as the first point, and the projection of the axes of the plurality of first through holes 142 on the first projection surface is set as a plurality of second points. At least two of the plurality of second points are not equidistant from the first point. That is to say, the plurality of first through holes 142 are asymmetrically distributed on the sealing gasket 140 around the exhaust chamber 134. By arranging the plurality of first through holes 142 in an asymmetrical manner on the sealing gasket 140, the sealing gasket 140 can avoid the back pressure hole 114 and the bypass hole 116. This prevents the sealing gasket 140 from covering and encroaching on the back pressure hole 114 and the bypass hole 116 during installation, thereby affecting the normal function of the back pressure chamber 132 and the bypass chamber 136.

[0084] Specifically, such as Figure 1 As shown, the axis of the vortex assembly 100 is I.

[0085] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0086] like Figure 1 and Figure 2 As shown, a bypass hole 116 is provided on the first disc body 112, and the bypass hole 116 communicates with the bypass cavity 136; the sealing gasket 140 is located on the side of the bypass hole 116 near the axis of the vortex assembly 100.

[0087] In this embodiment, such as Figure 1 and Figure 2 As shown, a bypass hole 116 is provided on the first disc 112 to provide a flow channel for gas. The bypass hole 116 communicates with the bypass cavity 136, allowing gas to enter the first vortex blade 118 from the bypass cavity 136 via the bypass hole 116, where it is compressed by the vortex assembly 100. The sealing gasket 140 is positioned on the side of the bypass hole 116 near the axis of the vortex assembly 100, allowing the sealing gasket 140 to avoid obstructing the bypass hole 116 while also providing space for the bypass cavity 136 to be formed.

[0088] Furthermore, the bypass port 116 and the bypass cavity 136 are connected by a one-way valve. When the compressor 200 is under full load conditions, the pressure in the bypass is not lower than the pressure in the bypass port 116, and the gas cannot enter the bypass cavity 136 through the bypass port 116. When the compressor 200 is under half load conditions, the pressure in the bypass cavity 136 is the suction pressure, and the gas in the compression cavity 186 enters the bypass cavity 136 through the bypass.

[0089] Specifically, such as Figure 2 As shown, the side of the bypass hole 116 closest to the axis of the vortex assembly 100 is C.

[0090] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0091] like Figure 1 and Figure 2 As shown, the sealing gasket 140 is projected along the axis of the scroll assembly 100 of the compressor 200 to obtain a first projection surface. The projection of the axis of the scroll assembly 100 on the first projection surface is a first point, the projection of the axis of the first through hole 142 on the first projection surface is a second point, and the projection of the axis of the bypass hole 116 on the first projection surface is a third point. The distance between the third point and the first point is less than the distance between the second point and the first point.

[0092] In this embodiment, such as Figure 1 and Figure 2 As shown, a first projection surface is obtained by projecting the sealing gasket 140 along the axis of the scroll assembly 100 of the compressor 200. The first projection surface is parallel to the upper surface of the first disc 112. The projection of the axis of the scroll assembly 100 on the first projection surface is set as the first point, the projection of the axis of the first through hole 142 on the first projection surface is set as the second point, and the projection of the axis of the bypass hole 116 on the first projection surface is set as the third point. The distance between the third point and the first point is less than the distance between the second point and the first point, so that a part of the sealing gasket 140 always provides clearance space for the bypass hole 116, thereby ensuring that space can be reserved for the formation of the bypass cavity 136 and avoiding encroachment on the formation space of the bypass cavity 136. By improving the structure of the sealing gasket 140 and the layout of the screw holes, the formation space of the bypass cavity 136 can be satisfied, while ensuring the sealing effect of the exhaust cavity 134, the back pressure cavity 132 and the bypass cavity 136.

[0093] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0094] like Figure 3 As shown, the width of the narrowest part of the sealing gasket 140 is greater than or equal to 3.5 mm.

[0095] In this embodiment, such as Figure 3 As shown, by setting the width of the sealing gasket 140 to be greater than or equal to 3.5 mm at its narrowest point, the sealing gasket 140 can ensure a good sealing effect even at its narrowest point, thus enabling the functions of the back pressure chamber 132 and the bypass chamber 136 to be realized.

[0096] This embodiment provides a vortex assembly 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0097] like Figure 4 As shown, the vortex assembly 100 also includes a moving disk 180, which includes a second disk body 182 and a second vortex blade 184. The second vortex blade 184 is connected to the second disk body 182 and cooperates with the first vortex blade 118. The first vortex blade 118 and the second vortex blade 184 form a plurality of compression cavities 186.

[0098] In this embodiment, such as Figure 4 As shown, the vortex assembly 100 also includes a moving disk 180, which includes a second disk body 182 and a second vortex blade 184. The second vortex blade 184 is connected to the second disk body 182. When the second disk body 182 rotates, the second vortex blade 184 also rotates. The second vortex blade 184 can mesh with the first vortex blade 118 and can rotate relative to the first vortex blade 118. Through the mutual cooperation between the stationary disk 110 and the moving disk 180, multiple compression chambers 186 can be formed between the first vortex blade 118 and the second vortex blade 184 to compress the gas.

[0099] Specifically, the compression chamber 186 is crescent-shaped. As the compressor 200 operates, the volume of the crescent-shaped compression chamber 186 gradually decreases, thereby realizing the function of compressing the gas in the crescent-shaped compression chamber 186.
