Description

Technical Field

[0001] The utility model relates to the technical field of compressors, and in particular to a scroll assembly and a compressor. Background Art

[0002] At present, the exhaust valve structure of the scroll compressor in the related technology is very important, such as Figure 5 and Figure 6 As shown, its components generally include a valve plate 1′, a valve disc 2′ and a baffle 3′. A through hole is opened at one end of the valve plate 1′, and the middle of the through hole is separated by a beam. The valve plate 1′ is connected to the exhaust hole 5′ of the static scroll 4′, so that when the gas pressure in the exhaust chamber is high, the valve plate 1′ can support the valve disc 2′ to prevent the valve disc 2′ from deforming. The baffle 3′ plays a role of limiting protection. The valve disc 2′ is between the two, one end is fixed to the scroll, and the other end seals the exhaust port of the valve plate 1′. When the gas pressure in the compression chamber is greater than the pressure outside the chamber, the valve disc 2′ opens to exhaust. After the end, if the pressure in the chamber is less than the pressure outside the chamber, the valve disc 2′ rebounds to cover the exhaust port to prevent external gas from flowing back and realize unidirectional movement of gas. However, this structure has certain problems. For example, the valve disc is located above the valve plate and is not in direct contact with the exhaust hole of the scroll. At this time, the thickness of the valve plate and the exhaust hole form a space above the exhaust hole of the chamber, which increases the length of the exhaust path, thereby affecting the exhaust efficiency and reducing the energy efficiency of the compressor.

[0003] Therefore, how to design a scroll assembly that can improve the energy efficiency of the compressor has become an urgent problem to be solved. Utility Model Content

[0004] The utility model aims to at least solve the problems of low exhaust efficiency and energy efficiency of the compressor.

[0005] To this end, a first aspect of the present invention provides a scroll assembly.

[0006] A second aspect of the present invention provides a compressor.

[0007] In view of this, the first aspect of the present invention proposes a scroll assembly, comprising: a static scroll, which is provided with an exhaust hole; a valve column, which is arranged in the exhaust hole, and the valve column is provided with an installation channel; a support structure, which is arranged in the installation channel, and the support structure and the inner wall surface of the installation channel form an air guide hole, and the air guide hole is connected to the exhaust hole; a valve plate, which is arranged on the static scroll, opposite to the air guide hole, and is used to open or close the air guide hole, and the support structure is used to support the valve plate when the valve plate closes the air guide hole.

[0008] The scroll assembly provided by the present invention includes a fixed scroll, a valve column, a support structure, and a valve plate. The fixed scroll is provided with an exhaust hole, and a valve column with a mounting channel is provided in the exhaust hole. The support structure is provided in the mounting channel and forms an air guide hole with the inner wall surface of the mounting channel. The valve plate is arranged relative to the air guide hole and can open or close the air guide hole, so that the gas in the compression chamber can be smoothly discharged through the air guide hole, ensuring the normal operation of the exhaust process. It can be understood that since the valve column is provided in the mounting channel, compared with the solution of providing a valve plate on the end face of the fixed scroll, the present application can reduce the length of the exhaust path, prevent exhaust loss, and thus improve the exhaust efficiency. At the same time, since the support structure is provided in the mounting channel, it can support the valve plate when the valve plate closes the air guide hole. Therefore, it can ensure that the valve plate can maintain a stable closed state under conditions such as gas pressure, and avoid the situation where the valve plate is deformed, sunken, or cannot be closed normally due to factors such as pressure, thereby ensuring the normal operation of the exhaust system.

[0009] The scroll assembly provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, optionally, the support structure includes: at least one support rib, which is arranged on the inner wall surface of the installation channel, and when the valve plate closes the air guide hole, one end surface of the support rib contacts the valve plate.

[0011] In these embodiments, at least one supporting rib can be provided on the inner wall surface of the mounting channel. When the valve plate closes the air guide hole, one end surface of the supporting rib contacts the valve plate, so that the valve plate is subjected to a more uniform supporting force when closing the air guide hole, further enhancing the stability of the valve plate in the closed state, and effectively preventing the valve plate from being deformed or damaged due to local uneven force, thereby ensuring the reliable operation of the exhaust system.

[0012] In some embodiments, optionally, there are multiple support ribs, multiple support ribs are connected at one end away from the inner wall of the installation channel, and multiple support ribs are arranged at intervals along the circumference of the installation channel at one end close to the inner wall of the installation channel.

[0013] In these embodiments, the number of support ribs can be set to multiple, and the multiple support ribs are connected at one end away from the inner wall of the installation channel, and the multiple support ribs are arranged at circumferential intervals along the installation channel at one end close to the inner wall of the installation channel. This arrangement of the support ribs can ensure that sufficient support force is provided to the valve plate while making the support force distribution more uniform and reasonable. Compared with other possible support methods, it can better adapt to the pressure conditions of the valve plate under different working conditions, further improve the stability and reliability of the valve plate when it is closed, and effectively reduce problems such as valve plate deformation and air leakage caused by poor support.

[0014] In some embodiments, the valve stem is optionally a non-metallic component.

[0015] In these embodiments, the valve column can be set as a non-metallic part, so that when the valve plate contacts the non-metallic valve column when closing the air guide hole, the noise generated when the valve plate hits the valve column can be effectively reduced, the noise problem during the exhaust process can be improved, the acoustic environment of the entire compressor during operation can be improved, and the impact of the low-frequency impact noise generated by the exhaust valve structure on the noise of the entire machine can be reduced.

[0016] In some embodiments, optionally, the exhaust hole is arranged on the end surface of the static vortex disk, the valve column protrudes from the end surface of the static vortex disk, and the length of the valve column protruding from the end surface of the static vortex disk is greater than 0 mm and less than or equal to 0.5 mm.

[0017] In these embodiments, the exhaust hole is provided on the end face of the static vortex, that is, the exhaust hole is opened from the end face of the static vortex. The valve post is provided to protrude from the end face of the static vortex, thereby ensuring that the valve post can make good contact with the valve disc, which not only facilitates the accurate coordination of the valve disc with the valve post when opening and closing the air guide hole, but also ensures that the gas can pass smoothly through the air guide hole during the exhaust process. Among them, the length of the valve post protruding from the end face of the static vortex is greater than 0mm and less than or equal to 0.5mm, which can not only ensure that the valve post has good contact with the valve disc, but also prevent the valve disc from being deformed due to the valve disc hitting the valve post for a long time.

[0018] In some embodiments, optionally, the exhaust hole is provided on the end surface of the static vortex, and the end surface of the valve post close to the valve plate is flush with the end surface of the static vortex.

[0019] In these embodiments, the exhaust hole can be set on the end face of the static vortex, and the end face of the valve column close to the valve plate can be set flush with the end face of the static vortex. Such a setting allows the valve column and the static vortex to form a flat contact surface on the side where the valve plate is located, which is beneficial to the stable cooperation between the valve plate, the valve column and the static vortex when opening and closing the air guide hole, ensuring the smoothness of gas flow and the accuracy of the valve plate movement, and avoiding problems such as gas leakage or valve plate jamming due to uneven contact surface.

[0020] In some embodiments, optionally, the valve post is interference fit with the exhaust hole.

[0021] In these embodiments, the valve plate and the exhaust hole can be set to have an interference fit, so that the valve column can be fixed in the exhaust hole, ensuring that there is no gap between the valve column and the exhaust hole, thereby ensuring the stability and reliability of the exhaust system.

[0022] In some embodiments, the valve stem is optionally threadedly connected to the exhaust hole.

[0023] In these embodiments, the valve column can be threadedly connected to the exhaust hole. The threaded connection not only fixes the valve column, but also facilitates the disassembly and installation of the valve column, thereby improving the overall assembly efficiency of the compressor.

[0024] In some embodiments, optionally, the valve post is integrally formed with the static scroll.

[0025] In these embodiments, the valve column and the static scroll can also be integrally formed. The integrated structure is stable and reliable, and can ensure that the valve column will not loosen or shift during the operation of the compressor, especially during the exhaust process, thereby ensuring the stability and reliability of the exhaust system.

[0026] In some embodiments, optionally, the scroll assembly further comprises: a groove, which is provided on the end surface of the fixed scroll on a side close to the valve plate and is at least partially covered by the valve plate.

[0027] In these embodiments, a groove can also be provided on the end face of the stationary vortex close to the valve plate, and at least a portion of the groove can be covered by the valve plate, so that the lubricating oil can be prevented from filling the valve plate and the end face area of ​​the stationary vortex through the groove, thereby preventing the valve plate from being unable to open due to the presence of lubricating oil, ensuring that the valve plate can be opened and closed normally according to the exhaust requirements, and ensuring the normal operation of the exhaust system.

[0028] In some embodiments, optionally, the scroll assembly further includes: a limiting member, which is provided on the stationary scroll and is located on a side of the valve plate away from the stationary scroll, for limiting the valve plate.

[0029] In these embodiments, a limit member is provided on the static vortex and on the side of the valve plate away from the static vortex, which can accurately limit the valve plate and ensure that the movement range of the valve plate when opening and closing the air guide hole is within the specified range, avoiding excessive movement of the valve plate causing collision with other components or failure to accurately close the air guide hole, thereby ensuring the normal operation of the exhaust system.

[0030] In some embodiments, optionally, the valve plate is an elastic member, one end of the valve plate is connected to the static vortex, and the other end of the valve plate can move between a first position and a second position, closing the air guide hole when the other end of the valve plate is in the first position, and opening the air guide hole when the other end of the valve plate is in the second position; the surface of the limit member close to the side of the valve plate is the limit surface, and the limit surface is inclined from one end of the limit member to the other end toward the direction close to the valve plate, and the other end of the limit member is connected to the static vortex.

[0031] In these embodiments, the valve disc is an elastic member and one end of the valve disc is connected to the static vortex, and the other end can move between a first position (closing the air guide hole) and a second position (opening the air guide hole). At the same time, the surface of the limiting member close to the valve disc is a limiting surface and is tilted. This design allows the valve disc to move more smoothly when opening and closing the air guide hole, and the tilted setting of the limiting surface can more accurately limit the tilting angle of the valve disc, thereby avoiding the valve disc from getting stuck or exceeding the specified range during the movement, thereby ensuring the efficient and stable operation of the exhaust system. Specifically, the limiting surface is tilted from one end of the limiting member to the other end in the direction close to the valve disc, and the other end of the limiting member is connected to the static vortex. That is, when the valve disc closes the air guide hole, the gap between the limiting surface and the valve disc becomes smaller and smaller from one end of the limiting member to the other end.

[0032] A second aspect of the present invention provides a compressor, comprising: a scroll assembly as in any technical solution of the first aspect.

[0033] The compressor provided in this application includes the scroll assembly of any one of the technical solutions of the first aspect.

The support structure 12 is arranged in the mounting channel 112, and the support structure 12 and the inner wall surface of the mounting channel 112 form an air guide hole 114, and the air guide hole 114 is connected to the exhaust hole 102. The valve plate 13 is arranged on the static scroll 10, and is arranged opposite to the air guide hole 114, and is used to open or close the air guide hole 114. The support structure 12 is used to support the valve plate 13 when the valve plate 13 closes the air guide hole 114.

[0052] The scroll assembly 1 provided by the present invention includes a static scroll 10, a valve column 11, a support structure 12 and a valve plate 13. An exhaust hole 102 is provided on the static scroll 10, and a valve column 11 with a mounting channel 112 is provided in the exhaust hole 102. The support structure 12 is provided in the mounting channel 112 and forms an air guide hole 114 with the inner wall surface of the mounting channel 112. The valve plate 13 is arranged relative to the air guide hole 114 and can open or close the air guide hole 114, so that the gas in the compression chamber can be discharged smoothly through the air guide hole 114, ensuring that the exhaust process proceeds normally. It can be understood that since the present application sets the valve column 11 in the mounting channel 112, compared with the solution of setting a valve plate on the end face of the static scroll 10, the present application can reduce the length of the exhaust passage, prevent exhaust loss, and thus improve the exhaust efficiency. At the same time, since the present application sets a support structure 12 in the installation channel 112, it can support the valve plate 13 when the valve plate 13 closes the air guide hole 114, thereby ensuring that the valve plate 13 can maintain a stable closed state under conditions such as gas pressure, avoiding the valve plate 13 from being deformed, sunken or unable to close normally due to factors such as pressure, thereby ensuring the normal operation of the exhaust system.

This arrangement of the support ribs 122 can ensure that sufficient support force is provided to the valve plate 13 while making the support force distribution more uniform and reasonable. Compared with other possible support methods, it can better adapt to the pressure conditions of the valve plate 13 under different working conditions, further improve the stability and reliability of the valve plate 13 when it is closed, and effectively reduce the deformation, air leakage and other problems of the valve plate 13 caused by poor support.

[0088] In these embodiments, the valve plate 13 is an elastic member and one end of it is connected to the static vortex 10, and the other end can move between a first position (closing the air guide hole 114) and a second position (opening the air guide hole 114). At the same time, the surface of the limiter 15 close to the valve plate 13 is a limiter surface 152 and is tilted. This design allows the valve plate 13 to move more smoothly when opening and closing the air guide hole 114, and the tilted setting of the limiter surface 152 can more accurately limit the tilting angle of the valve plate 13, avoiding the valve plate 13 from getting stuck or exceeding the specified range during the movement process, thereby ensuring the efficient and stable operation of the exhaust system. Specifically, the limiter surface 152 is tilted from one end of the limiter 15 to the other end in the direction close to the valve plate 13, and the other end of the limiter 15 is connected to the static vortex 10. That is, when the valve disc 13 closes the air guide hole 114 , the gap between the limiting surface 152 and the valve disc 13 becomes smaller from one end to the other end of the limiting member 15 .

[0090] According to an embodiment of the first aspect of the present invention, the first aspect of the present invention proposes a scroll assembly 1, which includes a fixed scroll 10 and an exhaust valve assembly. The exhaust valve assembly consists of two parts, one part includes a valve plate 13, a valve plate baffle (limiting member 15), and a screw component, and the valve plate 13 and the valve plate baffle are assembled into one body by screws; the other part consists of an exhaust valve column (valve column 11), which serves as a support for the valve plate 13. An exhaust through hole (installation channel 112) is provided on the valve column 11, and the middle of the through hole is separated by a straight beam or a herringbone beam (support structure 12) to prevent the valve plate 13 from sinking and deforming when the gas pressure in the exhaust chamber is high. The valve column 11 is made of non-metallic material. The metal valve plate 13 contacts the non-metallic valve column 11, which can reduce the noise generated when the valve plate 13 hits the valve column 11.

[0091] In some embodiments, optionally, a thread is provided on the exhaust valve column 11. By machining a thread on the exhaust valve column 11, it can be threadedly connected to the scroll exhaust hole 102, or fixed to the scroll exhaust hole 102 by an interference fit, thereby ensuring that the valve column 11 is stably installed inside the exhaust hole 102. The height difference between the upper end face of the exhaust valve column 11 and the end face of the stator is required to be 0mm to 0.5mm to ensure that the valve column 11 is in contact with the valve plate 13. In addition, on the end face of the stator, a groove 14 is provided in the middle area covering the valve plate 13, which can prevent the lubricating oil from filling the valve plate 13 and the end face area, causing the valve plate 13 to be unable to open.

[0092] The beneficial technical effects of this application are as follows:

[0093] The scroll assembly 1 of the present application redesigns the traditional valve plate into a cylindrical shape identical to the exhaust hole 102, named exhaust valve stem 11. This valve stem has a certain thickness and has an exhaust hole 102 formed therein, allowing it to be directly embedded within the passageway of the scroll exhaust hole 102. This ensures smooth discharge of gas from the compression chamber, ensuring the normal operation of the exhaust process, while also shortening the exhaust passageway length and preventing exhaust loss.

[0094] The key points of this application are:

[0095] The valve disc 13 is integrally fixed to the valve disc baffle (limiting member 15), while the valve stem 11 is a standalone structure that can be directly embedded in the scroll exhaust hole 102. This allows direct contact between the valve disc 13, the scroll end face, and the exhaust port, eliminating any additional gas space above the exhaust port and effectively preventing exhaust loss. Furthermore, the valve stem 11 is made of a non-metallic material, which reduces the noise generated when the valve disc 13 strikes the valve stem 11.

[0096] Among them, the principle of the valve plate 13 slapping the valve column 11 is as follows: the gas inside and outside the compression chamber is separated, and when the gas pressure inside the compression chamber is greater than the gas pressure outside the compression chamber, the exhaust valve plate 13 allows communication between the inside and outside of the compression chamber. When the gas pressure outside the compression chamber is greater than the gas pressure inside the compression chamber, the exhaust valve plate 13 limits the communication between the inside and outside of the compression chamber. Therefore, when the gas pressure inside the compression chamber is greater than the gas pressure outside the compression chamber, the valve plate 13 will open, and the compression chamber will undergo an exhaust process. After the exhaust is completed, when the gas pressure inside the compression chamber is less than the gas pressure outside the compression chamber, the valve plate 13 will rebound and re-cover the exhaust port, and the external gas will not flow back into the compression chamber, realizing the one-way movement of the gas.
