DETAILED DESCRIPTION

[0044] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Reference below Figure 1-Figure 11 The exhaust valve assembly 1 of the compressor according to the embodiment of the utility model is described. By setting the first valve plate 112 of the exhaust valve plate 11 to be tilted downward, the main exhaust hole 21 of the first scroll 2 can be closed, and the phenomenon of the first valve plate 112 tilting up when the connection of the first valve positioning part 111 is unreliable can be reduced, and the sealing performance is better.

[0046] like Figure 1-Figure 11 As shown, an exhaust valve assembly 1 of a compressor according to an embodiment of the utility model includes an exhaust valve plate 11, the exhaust valve plate 11 includes a first valve positioning portion 111 and a first valve plate 112 connected to the first valve positioning portion 111, the first valve positioning portion 111 is used to connect to the first scroll 2 of the compressor, and the first valve plate 112 is used to close and open the first exhaust hole 21 of the first scroll 2.

[0047] That is to say, one end of the exhaust valve plate 11 is connected to the first scroll 2 through the first valve positioning portion 111, and the other end of the exhaust valve plate 11 is covered at the main exhaust hole 21 through the first valve plate 112. The first valve plate 112 can move relative to the first valve positioning portion 111 to open or close the first exhaust hole 21.

[0048] Specifically, the exhaust valve assembly 1 is connected to the first scroll 2 and can be used as an exhaust switch at the first scroll 2. The exhaust valve plate 11 is located at the exhaust end of the first scroll 2. When exhaust is required, the exhaust valve plate 11 is opened relative to the first scroll 2 to achieve exhaust. When exhaust is not required, the exhaust valve plate 11 is closed relative to the first scroll 2 to achieve sealing of the exhaust end of the first scroll 2. Among them, the exhaust valve plate 11 includes a first valve positioning portion 111 and a first valve plate 112 connected to each other. During actual processing, the two can be an integrated structure, wherein the first valve positioning portion 111 is used to connect and fix the exhaust valve plate 11 to the first scroll 2, and the two can be connected by bolts and other connecting parts. The first scroll 2 is provided with a first exhaust hole 21 at the exhaust end, and the first valve plate 112 is covered on the first exhaust hole 21 to achieve the closure of the first exhaust hole 21. When exhausting, the gas is discharged from the first exhaust hole 21 to push the first valve plate 112 to open relative to the first exhaust hole 21 to achieve exhaust of the first scroll 2.

[0049] The first valve disc 112 is tilted downward at a first predetermined angle α relative to the first valve positioning portion 111. Specifically, the first valve positioning portion 111 is constructed as a plane structure, and the first valve disc 112 is tilted downward relative to the first valve positioning portion 111, and is tilted toward one side of the first exhaust hole 21. In this way, under normal installation and when exhaust is not performed, the first valve disc 112 is pressed and matched with the first exhaust hole 21, and the two are more tightly connected, which can improve the sealing effect of the first valve disc 112 at the first exhaust hole 21. At the same time, when the first valve positioning portion 111 is connected to the first scroll 2, there may be problems of unreliable connection such as loose connection or extrusion of other parts. However, in this embodiment, the downward tilt angle of the first valve disc 112 can make up for the problem of unreliable connection on one side of the first valve positioning portion 111, that is, the phenomenon of the first valve disc 112 tilting upward in the above-mentioned installation state can be reduced, so that the first valve disc 112 can completely seal and cover the first exhaust hole 21, improve the sealing at the first exhaust hole 21, reduce air leakage, and thus improve the working performance of the first scroll 2. The exhaust valve plate 11 has a simple overall structure, is easy to implement, has strong practicality, and has lower cost.

[0050] According to the exhaust valve assembly 1 of the embodiment of the utility model, by setting the first valve plate 112 to tilt downward, the first exhaust hole 21 of the first scroll 2 can be closed, and the phenomenon of the first valve plate 112 tilting up when the first valve positioning part 111 is not reliably connected can be reduced, thereby enhancing the sealing of the exhaust valve plate 11, and the structure is simple and easy to implement.

[0051] In some embodiments, the first predetermined angle α is less than or equal to 0.6°. Specifically, the first scroll 2 is provided with a connecting hole on a side away from the first exhaust hole 21, and the first valve positioning portion 111 is connected to the first scroll 2 by a bolt, and the first valve plate 112 is used to cover the first exhaust hole 21 on a side away from the first valve positioning portion 111. Figure 2 and Figure 7 As shown, the first predetermined angle is used to limit the inclination of the first valve disc 112 relative to the first valve positioning portion 111, wherein the first predetermined angle α can be set to 0.6°, 0.5°, 0.4°, etc. By setting the first predetermined angle to the above values, it can be ensured that the first valve disc 112 completely covers the first exhaust hole 21 to ensure the sealing of the first valve disc 112 to the first exhaust hole 21. In actual manufacturing, the inclination angle of the first valve disc 112 relative to the first valve positioning portion 111 may have deviations. By setting the direction and value range of the first predetermined angle, the processing accuracy of the first valve disc 112 can be ensured to reduce the problem of poor sealing caused by manufacturing errors and improve the sealing of the exhaust valve disc 11. The value of the first predetermined angle α is not limited to that described in this embodiment, and can be set according to the actual space.

[0052] Therefore, the first predetermined angle α cannot be set too large or too small, which is not conducive to the first valve plate 112 completely covering the first exhaust hole 21. Setting the first predetermined angle α to be less than or equal to 0.6° can meet the above two usage requirements.

[0053] In some embodiments, the exhaust valve assembly 1 also includes an elastic member 12, the elastic member 12 includes a spring-loaded positioning portion 121 and a spring-loaded plate 122 connected to the spring-loaded plate positioning portion 121, the spring-loaded plate positioning portion 121 is connected to the first valve positioning portion 111, the spring-loaded plate 122 is opposite to the first valve plate 112, and the spring-loaded plate 122 is tilted upward at a second predetermined angle β relative to the spring-loaded plate positioning portion 121.

[0054] Specifically, the elastic member 12 is used to be connected to the exhaust valve plate 11, and is located on the side of the exhaust valve plate 11 away from the first exhaust hole 21. The elastic member 12 has an elastic effect, and when the exhaust valve plate 11 is opened at a certain angle, it can play an elastic buffering role on the exhaust valve plate 11. The elastic member 12 includes a connected spring plate positioning portion 121 and a spring plate 122. In actual processing, the two can be an integrated structure, wherein the spring plate positioning portion 121 is used to connect and fix the elastic plate to the first valve positioning portion 111, and the two can be connected by bolts and other connecting parts, and the spring plate 122 is relatively distributed with the first valve plate 112, so that when exhausting, the gas pushes the first valve plate 112 to open relative to the first exhaust hole 21 and press and contact with the spring plate 122.

[0055] And if Figure 3-Figure 5As shown, the spring sheet positioning portion 121 is constructed as a planar structure, and the spring sheet 122 is inclined upward relative to the spring sheet positioning portion 121, and is inclined toward the side away from the first exhaust hole 21, so that the spring sheet 122 is spaced apart from the first valve sheet 112 and is inclined toward the side away from each other. During the exhaust process, the first valve sheet 112 will not encounter resistance when opening, and when the first valve sheet 112 is opened to contact with the spring sheet 122, the spring sheet 122 has a certain elasticity to the first valve sheet 112, thereby reducing the impact of the first valve sheet 112 opening upward.

[0056] In some embodiments, Fig. 9 As shown, the bending angle corresponding to the maximum lift of the exhaust valve plate 11 is θ, and the second predetermined angle β and the bending angle θ satisfy: 0.9×θ≤β≤1.05×θ. Specifically, when exhausting, when the first valve plate 112 of the exhaust valve plate 11 opens upward to the maximum lift, the corresponding bending angle is the maximum bending angle of the first valve plate 112, and the bending angle of the first valve plate 112 is set to θ, wherein the second predetermined angle β can take values ​​of: 0.9×θ, 0.95×θ, 1.0×θ, etc., that is, the bending angle is less than or equal to the second predetermined angle β. The angle can ensure that the first valve plate 112 can contact the elastic member 12 at the maximum lift, so that the exhaust valve plate 11 contacts the elastic member 12 at a high speed and the stiffness increases in the later stage, accelerating its fall at this time. The upper side of the elastic member 12 is also connected to the lift limiter 3. Through the above angle setting, it is ensured that during the normal opening and closing process of the exhaust valve plate 11, on the one hand, the exhaust valve plate 11 reduces the direct impact of the lift limiter 3 and the vibration when falling back, and on the other hand, it also reduces the reflux of the exhaust refrigerant, which is beneficial to improve energy efficiency. The value of the second predetermined angle β is not limited to that described in this embodiment, and can be flexibly selected.

[0057] Therefore, the second predetermined angle β cannot be set too large, which is not conducive to the first valve plate 112 contacting the elastic member 12 when it is at the maximum lift. The value of the second predetermined angle β satisfies 0.9×θ≤β≤1.05×θ, which can meet the above setting requirements.

[0058] In some embodiments, the projection of the connection position between the spring 122 and the spring positioning portion 121 falls into the first valve positioning portion 111. Specifically, as Figure 2 , Figure 4 and Figure 7As shown, the spring piece positioning portion 121 and the first valve positioning portion 111 are both planar structures, and the two are fitted together, wherein the spring piece positioning portion 121 and the first valve positioning portion 111 extend in the same direction, and the extension length of the spring piece positioning portion 121 is less than the extension length of the first valve positioning portion 111, so that the projection of the connection position between the spring piece 122 and the spring piece positioning portion 121 is located in the first valve positioning portion 111, and similarly, the projection of the connection position between the first valve plate 112 and the first valve positioning portion 111 is located in the spring piece 122. During the exhaust process, the first valve plate 112 opens a certain angle relative to the main exhaust hole 21 toward the spring piece 122 and then contacts the spring piece 122, pushing the spring piece 122 to continue to open. During this process, the first valve plate 112 will not be subject to the resistance of the spring piece positioning portion 121, so that the main exhaust hole 21 is exhausted smoothly, thereby improving the exhaust efficiency. Therefore, by staggering the connection positions of the two, it is beneficial to improve the exhaust efficiency of the first scroll 2.

[0059] and / or, if Figure 2 and Figure 4 As shown, the thickness t1 of the exhaust valve plate 11 and the thickness t2 of the elastic member 12 satisfy t1<t2, that is, the thickness of the elastic member 12 is greater than the thickness of the exhaust valve plate 11. In this way, during the exhaust process, the first valve plate 112 of the exhaust valve plate 11 opens a certain angle toward the spring plate 122 and then contacts and presses against the spring plate 122. When the bending angle of the exhaust valve plate 11 is maximum, the two press against the lift limiter 3, which can reduce the direct impact force of the first valve plate 112 on the lift limiter 3. The elastic buffering effect of the elastic member 12 is good, which can improve the stability of each structure during the exhaust process and increase the service life of the lift limiter 3.

[0060] In some embodiments, the spring 122 includes a spring head 123 and a spring bending portion 124, and the two ends of the spring bending portion 124 are respectively connected to the spring positioning portion 121 and the spring head 123. Specifically, as Figure 7 As shown, the spring clip bending portion 124 is located between the spring clip head portion 123 and the spring clip positioning portion 121, and the spring clip positioning portion 121, the spring clip bending portion 124 and the spring clip head portion 123 are connected in sequence, wherein the spring clip positioning portion 121 is a planar structure, the spring clip bending portion 124 is bent upward along a side of the spring clip positioning portion 121 close to the spring clip head portion 123, and the bending angle is a second predetermined angle β, and the extension length of the spring clip bending portion 124 is greater than the extension length of the spring clip positioning portion 121.

[0061] Among them, Figure 3 , Figure 5 and Figure 6As shown, the shrapnel head 123 is configured as an arc shape, and the diameter of the arc can be larger than the aperture of the first exhaust hole 21, so that the structure of the shrapnel head 123 is smooth, and the arc-shaped structure is regular and basic in shape, which is simple and convenient to process. The arc-shaped shrapnel head 123 saves materials and has the effect of reducing weight, which is beneficial for the first valve plate 112 to push the shrapnel head 123 to move. And / or, the width of the spring clip bending portion 124 gradually decreases from the spring clip head 123 to the spring clip positioning portion 121, wherein the spring clip head 123 is tangentially connected to the spring clip bending portion 124, the width of the spring clip bending portion 124 near the spring clip head 123 is greater than the width at the spring clip positioning portion 121, and gradually decreases from the spring clip head 123 to the spring clip positioning portion 121, so that the connection between the three is more coherent, and by setting the width of the spring clip bending portion 124 to be gradual, the resistance of the spring clip 122 to the first valve plate 112 can be reduced, so that the first valve plate 112 can be opened smoothly, while saving materials and reducing costs.

[0062] In some embodiments, the first valve plate 112 includes a first valve head portion 113 and a first valve bending portion 114, and two ends of the first valve bending portion 114 are respectively connected to the first valve head portion 113 and the first valve positioning portion 111. Specifically, as Figure 1 As shown, the first valve bending portion 114 is located between the first valve head portion 113 and the first valve positioning portion 111, and the first valve positioning portion 111, the first valve bending portion 114 and the first valve head portion 113 are connected in sequence, wherein the first valve positioning portion 111 is a planar structure, the first valve bending portion 114 is bent downward along a side of the first valve positioning portion 111 close to the first valve head portion 113, and the bending angle is a first predetermined angle α, and the extension length of the first valve bending portion 114 is greater than the extension length of the first valve positioning portion 111.

[0063] Among them, the first valve head 113 is configured as an arc shape, so that the structure of the first valve head 113 is smooth, and the arc structure is regular and basic, and the processing is simple and convenient. The arc-shaped first valve head 113 matches the shape of the first exhaust hole 21, and the arc diameter of the first valve head 113 is larger than the aperture of the first exhaust hole 21, which is conducive to the first valve head 113 completely covering the first exhaust hole 21, with a good sealing effect and reduced air leakage. The arc diameter of the first valve head 113 can be the same as the arc diameter of the spring head 123, and the arc-shaped first valve head 113 saves materials and has the effect of reducing weight, which is conducive to the first valve plate 112 opening the first exhaust hole 21 to achieve exhaust. And / or, the width of the first valve bending portion 114 gradually decreases from the first valve head portion 113 to the first valve positioning portion 111, wherein the first valve head portion 113 is tangentially connected to the first valve bending portion 114, the width of the first valve bending portion 114 near the first valve head portion 113 is greater than the width at the first valve positioning portion 111, and gradually decreases from the first valve head portion 113 to the first valve positioning portion 111, so that the connection between the three is coherent and smooth, and by setting the width of the spring sheet bending portion 124 to be gradual, it is beneficial for the gas to break through the first valve sheet 112 and be discharged quickly during exhaust, while saving materials and reducing costs.

[0064] In some embodiments, the exhaust valve plate 11 also includes a second valve positioning portion 125, a second valve plate 126 and a connecting portion 127. The second valve plate 126 is connected to the second valve positioning portion 125. The connecting portion 127 connects the second valve positioning portion 125 and the first valve positioning portion 111. The second valve plate 126 is used to close and open the second exhaust hole of the first scroll 2. The second valve plate 126 can move relative to the second valve positioning portion 125 to open or close the second exhaust hole.

[0065] The first scroll 2 is provided with a first exhaust hole 21 and a second exhaust hole, and both the second exhaust hole and the first exhaust hole 21 are used to discharge the gas in the first scroll 2, wherein the second exhaust hole is used to release the gas in the compression chamber in advance under low pressure and low speed conditions, and the first exhaust hole 21 is used to discharge the compressed gas. Figure 1 As shown, the exhaust valve disc 11 also includes a second valve positioning portion 125, a second valve disc 126 and a connecting portion 127 connected to each other. The second valve positioning portion 125 is located between the second valve disc 126 and the connecting portion 127, and the connecting portion 127 connects the second valve positioning portion 125 with the first valve positioning portion 111. In actual design, the three can be an integrated structure with the first valve positioning portion 111 and the first valve disc 112, wherein the first valve positioning portion 111 is used to connect and fix the exhaust valve disc 11 with the first scroll 2, and the two can be connected by bolts and other connecting parts. In actual operation, under low-pressure and low-speed working conditions, the second valve disc 126 opens the second exhaust hole for pressure relief, which can prevent the gas in the compression chamber from being over-compressed immediately before the first valve disc 112 opens, thereby reducing the working efficiency.

[0066] Among them, the second exhaust hole of the first scroll 2 can be multiple, and correspondingly, the second valve plate 126, the second valve positioning part 125 and the connecting part 127 are also multiple, so as to realize pressure relief at multiple locations of the first scroll 2 and improve the pressure relief speed, and the second valve plate 126, the second valve positioning part 125 and the connecting part 127 form an auxiliary exhaust valve plate, and the second valve plate 126, the second valve positioning part 125 and the connecting part 127 can all be two, three, etc. In the present embodiment, there are two second valve plates 126, the second valve positioning part 125 and the connecting part 127, and the two auxiliary exhaust valve plates are symmetrically distributed relative to the first valve plate 112, so that the overall structure of the exhaust valve plate 11 is symmetrical and regular.

[0067] In some embodiments, the head of the first valve disc 112 is configured as an arc with a diameter of φ1, and the head of the second valve disc 126 is configured as an arc with a diameter of φ2, wherein 1.5×φ2≤φ1≤2×φ2, specifically, as Figure 1 and Figure 6 As shown, the head of the second valve disc 126 and the head of the first valve disc 112 can both be constructed in an arc shape, and the arc diameter of the head of the first valve disc 112 is φ1, and the arc diameter of the head of the second valve disc 126 is φ2, and 1.5×φ2≤φ1≤2×φ2 is satisfied, that is, the arc diameter of the head of the first valve disc 112 can be 1.5 times, 1.7 times, etc. of the arc diameter of the head of the second valve disc 126, and correspondingly, the aperture difference between the first exhaust hole 21 and the aperture of the second exhaust hole matches the above value, which can improve the sealing performance of the first exhaust hole 21 and the second exhaust hole respectively, and by setting the size difference between the two, it is beneficial for the second valve disc 126 to open the second exhaust hole in time for pressure relief under low-pressure and low-speed conditions, thereby reducing the occurrence of excessive compression of gas during exhaust and improving compression performance.

[0068] In some embodiments, the first scroll 2 is a stationary scroll, and the second scroll is a movable scroll, wherein the stationary scroll is static and the movable scroll can move relative to the stationary scroll, and both the stationary scroll and the movable scroll are provided with a bottom plate and a plurality of vortex teeth, and a compression channel is formed between the plurality of vortex teeth, so that during operation, the movable scroll can translate around a predetermined axis, and the fluid entering the compression channel is gradually compressed, and the compressed fluid is driven to flow from the outside to the inside along the radial direction of the stationary scroll, and when the exhaust valve plate 11 opens the first exhaust hole 21, the fluid is driven to be sent out from the first exhaust hole 21, so as to realize the compression of the gas and discharge the compressed gas.

[0069] Also, it should be noted that the technical solution of the present application adopts a multi-tooth scroll structure, which utilizes the characteristics of multiple teeth. Compared with traditional volumetric compressors, engines and other structures, it has fewer moving parts, simpler assembly, less vibration and noise, and a small overall structural size, which can make the conversion process smooth.

[0070] In some embodiments, the first valve positioning portion 111 is the main valve positioning portion, the first valve plate 112 is the main valve plate, and the second valve plate 126 is the auxiliary valve plate, and the first exhaust hole 21 is the main exhaust hole, and the second exhaust hole is the auxiliary exhaust hole. That is to say, the exhaust side of the compressor is provided with a main exhaust hole 21 for exhaust and an auxiliary exhaust hole for pressure relief. During the exhaust process, the main valve positioning portion is used to connect the exhaust valve plate 11 to the static scroll plate, and the main valve plate is used to close and open the main exhaust hole to realize the opening and closing of the main exhaust duct, and under low-pressure and low-speed conditions, the auxiliary valve plate opens the auxiliary exhaust hole in time to relieve pressure, thereby reducing the occurrence of excessive compression of gas during exhaust and improving compression performance.

[0071] The utility model also provides an exhaust assembly 100 of a compressor.

[0072] According to an embodiment of the utility model, the exhaust assembly 100 of the compressor includes a first scroll 2 and an exhaust valve assembly 1 according to any one of the above embodiments, the first scroll 2 has a first exhaust hole 21, a first valve positioning portion 111 is connected to the first scroll 2, and the first valve plate 112 is inclined toward the first scroll 2 relative to the first valve positioning portion 111.

[0073] Specifically, the exhaust valve assembly 1 is applied to the first scroll 2, and the exhaust end of the first scroll 2 is connected to the exhaust valve assembly 1, and the exhaust valve assembly 1 is connected to the first exhaust hole 21 of the first scroll 2. After the compressor is working, the compressed high-pressure gas is discharged from the exhaust chamber of the first scroll 2 and the first exhaust hole 21, wherein the first valve positioning portion 111 of the exhaust valve plate 11 of the exhaust valve assembly 1 is closely connected to the first scroll 2, and the first valve plate 112 covers the first exhaust hole 21 and is inclined toward the first scroll 2 relative to the first valve positioning portion 111, so that the first valve plate 112 and the first exhaust hole 21 can be pressed and matched, and the two can fit tightly, and at the same time, the inclination angle of the first valve plate 112 toward the side of the first scroll 2 is a first predetermined angle, which can reduce the phenomenon of the first valve plate 112 warping upward, effectively improve the sealing of the exhaust valve assembly 1, and prevent air leakage at the first exhaust hole 21.

[0074] In some embodiments, the first exhaust hole 21 is inclined relative to the first scroll 2 at a third predetermined angle γ. Specifically, the axis of the first exhaust hole 21 is inclined relative to the first scroll 2, and the inclination angle is set to the third predetermined angle γ. Figure 8-Figure 11 As shown, the third predetermined angle is the angle between the axis of the first exhaust hole 21 and the end face of the exhaust end of the first scroll 2. In this way, by tilting the first exhaust hole 21, the gas discharge path can be increased. While ensuring normal exhaust, the direct impact of the high-pressure gas compressed in the cavity of the second scroll and the first scroll 2 on the exhaust valve plate 11 is reduced, thereby reducing the exhaust impact force in this process and reducing the reliability risk of the exhaust valve plate 11 during the entire movement process.

[0075] In some embodiments, the third predetermined angle γ satisfies 45°≤γ≤60°. Specifically, the third predetermined angle is used to reflect the exhaust path of the first exhaust hole 21 at the exhaust end of the first scroll 2. Different angles have different exhaust path lengths. In actual design, the third predetermined angle γ of the first exhaust hole 21 can be 45°, 50°, 60°, etc. By setting these three values, the exhaust path length of the first exhaust hole 21 can be increased. Compared with the setting of the first exhaust hole 21 perpendicular to the exhaust end of the first scroll 2, the inclined setting effectively increases the exhaust path of the compressed gas, thereby reducing the direct impact of the compressed gas on the exhaust valve plate 11 and reducing the impact force of the exhaust, thereby reducing the impact stress of the exhaust valve plate 11 on the main exhaust hole 21 during the opening and closing process, improving the fatigue resistance of the exhaust valve plate 11, and extending the service life of the exhaust valve plate 11. The value of the third predetermined angle γ is not limited to that described in this embodiment, and can be flexibly set according to actual needs.

[0076] And / or, the first exhaust hole 21 is inclined in the exhaust direction away from the first valve positioning portion 111, such as Fig. 9 As shown, the first valve positioning portion 111 is the fixed end of the exhaust valve plate 11, and the first valve plate 112 is the movable end and moves relative to the first exhaust hole 21 during exhaust. The first exhaust hole 21 is arranged in the exhaust direction and is inclined in the direction away from the first valve positioning portion 111. In this way, during the exhaust process, the resistance at the first valve plate 112 is small, which is conducive to the high-pressure gas to quickly push the first valve plate 112 to open the first exhaust hole 21, thereby realizing rapid exhaust of gas, and the structure is simple and easy to implement.

[0077] In some embodiments, a sink 22 is provided on the back side of the first scroll 2 , an exhaust hole is provided on the bottom surface of the sink 22 , and the exhaust valve assembly 1 is provided in the sink 22 .

[0078] Specifically, Fig.10 and Fig.11 As shown, the back side of the first scroll 2 is the exhaust end, and a sink 22 is provided on the back side of the first scroll 2, which can reduce the depth of gas discharge, wherein the bottom surface of the exhaust hole sink 22, the exhaust valve assembly 1 is located in the sink 22, and is connected to the bottom surface of the sink 22, during the exhaust process, the compressed high-pressure gas is discharged from the exhaust hole to the sink 22, and then discharged through the sink 22, thereby, by providing the sink 22, the axial depth of the first exhaust hole 21 is reduced, so that during exhaust, the gas in the first exhaust hole 21 is discharged to the sink 22 through a shorter axial depth, thereby ensuring the clearance volume of the exhaust process, facilitating rapid gas discharge, reducing exhaust pressure loss, and being beneficial to improving compression performance, and with such a configuration, the structure of the sink 22 is reasonably utilized to realize the installation of the exhaust valve assembly 1.

[0079] In some embodiments, at least one side surface of the trough 22 has at least two steps 221 for gradually expanding the trough 22 in the exhaust direction. That is, at least two steps 221 can be set on one side of the trough 22, or at least two steps 221 can be set on multiple sides of the trough 22. Both of these settings can enable the gas discharged from the first exhaust hole 21 to flow outward in the exhaust direction.

[0080] Specifically, Fig.10 and Fig.11 As shown, in the present embodiment, at least two steps 221 are provided on one side surface of the trough 22, that is, two steps 221 are provided on the side close to the first exhaust hole 21, the two steps 221 are spaced apart and distributed upward along the exhaust direction, and the two steps 221 can divide the depth of the trough 22 into equal parts, and the two steps 221 are staggered in the direction away from the first exhaust hole 21, so that after the gas is exhausted from the first exhaust hole 21, it continues to flow outwardly along the exhaust direction through the two steps 221, which can reduce the vortex phenomenon of high-pressure gas forming at the edge corner of the trough 22 during the exhaust process, causing the exhaust to be not smooth, reduce the airflow reflux caused by this part of the vortex gas to the discharged gas, and facilitate the smooth discharge of high-pressure gas.

[0081] The number of steps 221 can be three, four, etc., and the depth of steps 221 can be different, and can be selectively set according to the actual space. The outward expansion structure of the trough 22 can also be an inclined slope surface. As long as the airflow vortex phenomenon at the edge angle of the trough 22 can be alleviated, it can be adopted, with diverse choices and high flexibility.

[0082] and / or, if Fig.10 As shown, the bottom plate height H of the first scroll 2 and the depth H1 of the sink 22 satisfy 3×H1≤H≤4×H1. Specifically, the sink 22 is provided on the bottom plate of the first scroll 2 and is recessed toward one side of the exhaust cavity in the first scroll 2. The bottom plate height of the first scroll 2 is greater than the depth of the sink 22. The first exhaust hole 21 is provided between the exhaust cavity of the first scroll 2 and the sink 22. The bottom plate height of the first scroll 2 is H. The bottom plate height of the first scroll 2 is H1, and 3×H1≤H≤4×H1 is satisfied. That is, the bottom plate height of the first scroll 2 can be 3 times, 4 times, etc. of the bottom plate height of the first scroll 2. This arrangement can ensure the strength requirement of the bottom plate of the first scroll 2 after the sink 22 is provided, and improve the overall performance of the first scroll 2. The value of the bottom plate height of the first scroll 2 is not limited to that described in this embodiment, and can be flexibly selected according to the actual space size.

[0083] In some embodiments, the head of the first valve plate 112 is configured as an arc with a diameter of φ1, and the diameter φ of the first exhaust hole 21 satisfies the diameter φ1, 1.2×φ≤φ1≤1.4×φ. Specifically, the head of the first valve plate 112 covers the first exhaust hole 21 and is used to close or open the first exhaust hole 21. The arc diameter of the head of the first valve plate 112 needs to be larger than the diameter of the first exhaust hole 21. Fig.11 As shown, the arc diameter of the head of the first valve plate 112 is φ1, the diameter of the first exhaust hole 21 is φ, and 1.2×φ≤φ1≤1.4×φ is satisfied. That is to say, the arc diameter of the head of the first valve plate 112 can be 1.2 times, 1.3 times, 1.4 times, etc., of the diameter of the first exhaust hole 21. Correspondingly, the aperture of the second exhaust hole and the arc diameter difference of the second valve plate 126 can be set to match the above values, so that the first valve plate 112 can completely cover the first exhaust hole 21, and the second valve plate 126 can completely cover the second exhaust hole. In this way, the sealing of the first exhaust hole 21 and the second exhaust hole can be guaranteed, thereby improving the compression performance.

[0084] Among them, it should be noted that the surface of the first exhaust hole 21 and the mounting surface of the first valve positioning portion 111 both protrude from the bottom surface of the recess 22, and the protruding height value can be controlled according to the size of the first predetermined angle and the distance between the first exhaust hole 21 and the first valve positioning portion 111. With such a configuration, since the first valve plate 112 is tilted downward relative to the first valve positioning portion 111, it can be ensured that the first valve positioning portion 111 is closely connected to its mounting surface, and the first valve plate 112 can completely cover the surface of the first exhaust hole 21, thereby achieving effective sealing of the first exhaust hole 21.

[0085] In some embodiments, the exhaust assembly further includes a lift limiter 3 , and the exhaust valve assembly 1 is disposed between the lift limiter 3 and the first scroll 2 .

[0086] Specifically, the lift limiter 3 is used to limit the lifting stroke of the exhaust valve plate 11, wherein Figure 8As shown, the exhaust valve assembly 1 is located between the lift limiter 3 and the first scroll 2. The lift limiter 3 is installed at the exhaust end of the first scroll 2 and is detachably connected to the bottom surface of the groove 22. The lift limiter 3 can be connected to the first scroll 2 at the same position as the exhaust valve assembly 1. In this way, the installation steps are reduced and the assembly cost is reduced. The lift limiter 3 is provided with a limiting portion 31, which is arranged opposite to the spring plate 122 and the first valve plate 112. The limiting portion 31 is arranged tilted, and the limiting portion 31 is consistent with the inclination direction and angle of the spring plate 122 to ensure that the elastic member 12 can normally fit the limiting portion 31 of the lift limiter 3 at a special moment. During the exhaust process, the high-pressure gas is discharged from the first exhaust hole 21 to push the first valve plate 112 to lift. After the first valve plate 112 is in the maximum lifting stroke, the spring plate 122 is pushed to lift and press against the lift limiter 3, so that the first valve plate 112 is in a stable state, ensuring the exhaust stability. The lift limiter 3 can limit the excessive lifting of the first valve plate 112 to avoid the risk of breakage of the first valve plate 112 and affect the exhaust performance.
