[0003] The stationary scroll is one of the main components of a scroll compressor mechanism. To ensure sufficient strength, both the stationary base plate and the stationary scroll portion require adequate thickness.

[0020] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0022] The compressor is a crucial component of a vapor compression refrigeration system; its function is to compress low-pressure, low-temperature refrigerant gas into high-pressure, high-temperature refrigerant gas. (Please refer to...) Figures 1 to 10 This embodiment proposes a compressor, including a compression mechanism, a drive mechanism, and a housing assembly. The compression mechanism includes a fixed scroll member 1 and a moving scroll member 5. The fixed scroll member 1 includes a fixed base plate portion 11 and a fixed scroll portion 12, which are connected. The moving scroll member 5 includes a moving base plate portion 51 and a moving scroll portion 52, which are connected. The moving scroll portion 52 extends from the base plate portion 51 toward the fixed base plate portion 11, and the fixed scroll portion 12 extends from the fixed base plate portion 11 toward the moving base plate portion 51. The compressor has a compression chamber P and a suction force LP, which is located outside the compression chamber P. The compression chamber P is located between the fixed scroll member 1 and the moving scroll member 5. Specifically, the compression chamber P is located between the fixed base plate portion 11 and the moving base plate portion 51, and the compression chamber P is at least partially located between the moving scroll portion 52 and the fixed scroll portion 12. More specifically, the profiles of the moving scroll 52 and the fixed scroll 12 are offset by 180° and mesh with each other to form a series of compression chambers P. The series of compression chambers P includes the innermost central compression chamber P1 and the intermediate compression chamber P2 located between the central compression chamber P1 and the suction force LP. The intermediate compression chambers P2 are arranged in pairs, and the number of pairs is not specifically limited. The two intermediate compression chambers P2 in the same pair have a phase difference of 180°. The fixed base plate 11 has a main exhaust port O1, which can communicate with the central compression chamber P1. During the compression of the refrigerant, the moving scroll 5 moves in a plane with a small radius around the fixed scroll 1, thereby cooperating with the fixed base plate 11 and the moving base plate 51 to form a series of crescent-shaped cylindrical working chambers. The refrigerant is drawn into the compression chamber P from the suction chamber LP, and is gradually compressed from the outermost middle compression chamber P2 to the innermost central compression chamber P1, and the pressure gradually increases. When the pressure of the refrigerant in the central compression chamber P1 rises to the discharge pressure, it is discharged from the main discharge port O1.
[0023] Therefore, the stator scroll is one of the main components of the compression mechanism of a scroll compressor, and a key component in completing refrigerant compression. To ensure sufficient strength, both the stator base plate 11 and the stator scroll 12 require adequate thickness. However, designing the stator base plate 11 to be too thick significantly increases the weight of the component. For information on lightweight compressor design, please refer to [link to relevant documentation]. Figures 3 to 6The fixed base plate portion 11 described in this application has a weight-reducing groove 10a, and at least one of the weight-reducing grooves 10a extends along the length direction of the fixed base plate portion 11 toward the edge of the fixed base plate portion 11. In this embodiment, it extends from the center of the fixed base plate portion 11 toward the edge of the fixed base plate portion 11. In other words, at least one of the weight-reducing grooves 10a extends along the length direction at one end toward the center of the fixed base plate portion 11 and at the other end toward the edge of the fixed base plate portion 11. It is not limited to extending along the radial direction (with the center of the main exhaust port O1 as the radial center), but can also be as follows: Figure 5 The middle section of the weight-reducing groove (shown as 10a1) extends at a certain angle to the radial direction. Furthermore, the weight-reducing groove 10a is not limited to a straight line; it can also extend in the form of curves, wavy lines, arcs, etc., as not shown in the figure.
[0024] During the operation of the compressor compressing the refrigerant, the pressure within the compression mechanism gradually increases from the outside to the inside along the direction perpendicular to the thickness of the fixed base plate portion 11. Therefore, the pressure on the center portion of the fixed base plate portion 11 is higher than the pressure on the edge portion. To improve the structural strength of the center portion of the fixed base plate portion 11, at least one of the aforementioned weight-reducing grooves 10a extends along the length of the fixed base plate portion 11 towards its edge. In other words, the wall portion outside the weight-reducing groove 10a acts as a reinforcing part, connecting the center portion and the edge portion, thus ensuring the overall structural strength of the fixed base plate portion 11.
[0025] In order to further improve the structural uniformity of the fixed vortex component 1 and improve the uniformity of the force on the fixed base plate 11 during the compression of the refrigerant, in this embodiment, there are multiple weight-reducing grooves 10a, which are distributed along the circumference of the fixed base plate 11. The adjacent weight-reducing grooves 10a form reinforcing ribs, connecting the center and edge of the fixed base plate 11, thereby improving the structural uniformity of the fixed vortex component 1 and thus helping to improve the uniformity of the force on the fixed base plate 11.
[0026] The fixed substrate portion 11 is along the thickness direction ( Figure 2 The fixed scroll portion 12 (in the direction F shown) has a first side portion 11a and a second side portion 11b. The fixed scroll portion 12 is connected to the first side portion 11a, and the weight-reducing groove 10a is located on the second side portion 11b. The depth of the weight-reducing groove 10a is d; the thickness of the fixed base portion 11 is H, where d and H have the same unit, and 0.1≤d / H≤0.9. This application, by providing a weight-reducing groove 10a on the side of the fixed base portion 11 opposite to the fixed scroll portion 12 and optimizing the depth of the weight-reducing groove 10a, can both ensure the structural strength of the fixed base portion 11 and reduce the weight of the fixed scroll portion 1, thus contributing to the lightweight development of compressors.
[0027] Specifically, the fixed substrate portion 11 has a first end face 11a1 and a second end face 11a2 on both sides along the thickness direction. The first end face 11a1 is located on the first side portion 11a, and the second end face 11a2 is located on the second side portion 11b. The weight-reducing groove 10a extends from the second end face 11a2 toward the first end face 11a1 in the depth direction. This embodiment does not specifically limit the number of weight-reducing grooves 10a; it can be one, two, three, etc. Furthermore, the depth of the weight-reducing groove 10a is greater than or equal to 1 mm, and the depth of the weight-reducing groove 10a is less than or equal to 12 mm, that is, d ≥ 1 mm and d ≤ 12 mm, meaning the depth of the weight-reducing groove 10a is between 1 mm and 12 mm.
[0028] In this embodiment, the d / H ratio can be 0.1, 0.2, 0.22, 0.25, 0.27, 0.3, 0.35, 0.4, 0.45, 0.48, 0.5, 0.55, 0.57, 0.6, 0.63, 0.64, 0.65, 0.67, 0.7, 0.75, 0.8, 0.9, etc. Since there are many possible examples, they will not be listed here. Of course, the d / H ratio can also be less than 0.1 or greater than 0.9.
[0029] In some embodiments, 0.2 ≤ d / H ≤ 0.8, and further, 0.4 ≤ d / H ≤ 0.7, where H ≥ 7 mm. This means the ratio of the depth of the weight-reducing groove 10a to the thickness of the fixed base plate portion 11 is between 0.4 and 0.7, and the thickness of the fixed base plate portion 11 is at least 7 mm. This ensures the structural strength of the fixed base plate portion 11 while optimizing the depth of the weight-reducing groove 10a, thus maintaining the structural strength of the fixed scroll component 1 while reducing its weight. Furthermore, to further contribute to the lightweight development of the compressor, the fixed scroll component 1 is at least partially made of lightweight metal. In one specific embodiment, the fixed scroll component 1 is an integral lightweight metal component, such as an aluminum alloy component, and also possesses good pressure resistance, machinability, thermal conductivity, and corrosion resistance.
[0030] Please refer to it again. Figures 2 to 6 The fixed base plate portion 11 has a secondary exhaust port O2. Both the main exhaust port O1 and the secondary exhaust port O2 are located on the second end face 11a2, and at least one weight-reducing groove 10a extends along its length towards the space between the main exhaust port O1 and the secondary exhaust port O2. In this embodiment, the secondary exhaust ports O2 are arranged in pairs, with the same pair of secondary exhaust ports O2 centered on the main exhaust port O1. The secondary exhaust ports O2 are connected to the intermediate compression chamber P2. In this embodiment, both the main exhaust port O1 and the secondary exhaust port O2 can be used for exhaust, and the secondary exhaust port O2 can be used for pre-exhaust.
[0031] Please refer to it again. Figure 2 , Figure 3 and combined Figure 7The compressor includes an exhaust valve 3, which is connected to the fixed base plate 11. The exhaust valve 3 includes a main exhaust valve 31 and a secondary exhaust valve 32. The main exhaust valve 31 can open or block the main exhaust port O1, and the secondary exhaust valve 32 can open or block the secondary exhaust port O2. In this embodiment, the main exhaust valve 31 and the main exhaust port O1 are correspondingly arranged, and the secondary exhaust valve 32 and the secondary exhaust port O2 are correspondingly arranged one-to-one.
[0032] Specifically, the main exhaust valve section 31 includes a main valve plate section 31a and a main lift limiting section 31b. The main valve plate section 31a is located between the main lift limiting section 31b and the fixed base plate section 11, and the main valve plate section 31a can open or block the main exhaust port O1. The auxiliary exhaust valve section 32 includes a auxiliary valve plate section 32a and an auxiliary lift limiting section 32b. The auxiliary valve plate section 32a is located between the auxiliary lift limiting section 32b and the fixed base plate section 11, and the auxiliary valve plate section 32a can open or block the auxiliary exhaust port O2. More specifically, the weight reduction groove 10a includes at least one first weight reduction groove 10a1, and the first weight reduction groove 10a1 is at least partially located between the main exhaust valve section 31 and the auxiliary exhaust valve section 32. In one specific embodiment, the first weight-reducing groove 10a1 is located between the main exhaust valve section 31 and the auxiliary exhaust valve section 32, and the length direction of the first weight-reducing groove 10a1 extends towards the space between the main exhaust port O1 and the auxiliary exhaust port O2. However, the first weight-reducing groove 10a1 is not connected to the main exhaust port O1 and the auxiliary exhaust port O2. That is, there is a gap between the first weight-reducing groove 10a1 and the main exhaust port O1 and the auxiliary exhaust port O2, so that the valve plate can cover the exhaust port.
[0033] In this embodiment, the number of first weight-reducing grooves 10a1 can be one, that is, a first weight-reducing groove 10a1 is provided between one of the auxiliary exhaust valve parts 32 and the main exhaust valve part 31. The number of first weight-reducing grooves 10a1 can also be two, that is, a first weight-reducing groove 10a1 is provided between one of the auxiliary exhaust valve parts 32 and the main exhaust valve part 31. During operation, the valve plates (main valve plate part 31a and auxiliary valve plate part 32a) will generate a certain impact load on the fixed base plate part 11. Therefore, providing the first weight-reducing groove 10a1 between the main exhaust valve part 31 and the auxiliary exhaust valve part 32 can correspondingly form reinforcing ribs, reducing weight while ensuring structural strength. Of course, in this embodiment, the number of first weight-reducing grooves 10a1 can also be multiple, that is, there can be two or more first weight-reducing grooves 10a1 provided between the auxiliary exhaust valve part 32 and the main exhaust valve part 31.
[0034] In the above embodiment, the exhaust valve 3 further includes a connecting portion 33 and a fixing portion 34. The connecting portion 33 connects the main exhaust valve portion 31 and the auxiliary exhaust valve portion 32, and the fixing portion 34 connects the fixing connecting portion 33 and the fixed base plate portion 11. Specifically, the connecting portion 33 includes a valve plate connecting portion 33a and a lift-limiting connecting portion 33b. The valve plate connecting portion 33a connects the main valve plate portion 31a and the auxiliary valve plate portion 32a, and the lift-limiting connecting portion 33b connects the main lift-limiting portion 31b and the auxiliary lift-limiting portion 32b. The valve plate connecting portion 33a is located between the lift-limiting connecting portion 33b and the fixed base plate portion 11, and is then fixed by the fixing portion 34, that is, the valve plate connecting portion 33a is pressed between the lift-limiting connecting portion 33b and the fixed base plate portion 11. The fixing portion 34 can be a bolt, screw, or other fastener.
[0035] Furthermore, the surface perpendicular to the thickness direction of the fixed base plate portion 11 is defined as the projection surface. The projection of the first weight-reducing groove 10a1 on the projection surface does not coincide with the projections of the main valve plate portion 31a and the auxiliary valve plate portion 32a on the projection surface. The projection position of the first weight-reducing groove 10a1 on the projection surface coincides with the projection portion of the valve plate connecting portion 33a on the projection surface. Additionally, please refer again to... Figure 5 and Figure 7 and combined Figure 8 The weight-reducing groove 10a further includes at least one second weight-reducing groove 10a2, the projection of the second weight-reducing groove 10a2 on the projection plane does not coincide with the projection of the exhaust valve 3 on the projection plane. That is, when there are multiple weight-reducing grooves 10a, the projections of some weight-reducing grooves 10a are within the range of the exhaust valve 3's projection, and the projections of some weight-reducing grooves 10a are outside the range of the exhaust valve 3's projection.
[0036] Please see Figure 9 The fixed base plate portion 11 has a groove 10b located on one side of the line connecting the main exhaust port O1 and the auxiliary exhaust port O2, and the groove 10b is at a distance from the main exhaust port O1 and the auxiliary exhaust port O2. Furthermore, the projection of at least one of the main valve plate portion 31a, the auxiliary valve plate portion 32a, and the valve plate connecting portion 33a onto the projection surface coincides with the projection of the groove 10b onto the projection surface. In this embodiment, by providing the groove 10b, the contact area between at least one of the main valve plate portion 31a, the auxiliary valve plate portion 32a, and the valve plate connecting portion 33a and the fixed base plate portion 11 is reduced. This reduces the likelihood of the valve plate failing to properly seal the exhaust port due to unevenness of the second end face 11a2 caused by processing errors. Additionally, the groove 10b can accommodate impurities, reducing or preventing the valve plate from breaking due to impact loads caused by impurities located between the contact surfaces. In this embodiment, the groove 10b can also help reduce the weight of the fixed vortex component 1. In addition, the groove 10b and the weight reduction groove 10a can be connected.
[0037] In addition, please refer to again Figure 2 and combined Figure 9 The compressor includes an exhaust cover 2 and a seal 4. The seal 4 abuts against the exhaust cover 2 and the fixed scroll member 1. The compressor has an exhaust chamber HP, which is located between the exhaust cover 2 and the fixed base plate 11. By providing the seal 4, the exhaust chamber HP and the suction plate LP are isolated, preventing the high-pressure refrigerant in the exhaust chamber HP from leaking into the suction plate LP during compression, thus affecting the compressor's operating efficiency and minimizing overcompression. Specifically, the fixed base plate 11 also has a sealing groove 10c, located on the second side 11b, between the weight reduction groove 10a and the edge of the fixed base plate 11. The seal 4 is at least partially located within the sealing groove 10c, abutting against and sealing the exhaust cover 2 and the fixed base plate 11. In this embodiment, the sealing groove 10c is not the weight reduction groove 10a. The sealing groove 10c effectively positions the seal 4, preventing it from slipping and causing sealing failure. Of course, in some other embodiments, the sealing groove 10c may also be provided at the end of the exhaust cover 2 that abuts against the fixed base plate portion 11; in still other embodiments, the exhaust cover 2 is provided with a sealing groove 10c at the end that abuts against the fixed base plate portion 11, and the fixed base plate portion 11 is also provided with a sealing groove 10c (not shown in the figure). The sealing member 4 may be partially located in the sealing groove 10c of the exhaust cover 2 and partially located in the sealing groove 10c of the fixed base plate portion 11, or a sealing member 4 may be provided in the sealing groove 10c of the exhaust cover 2 and the sealing groove 10c of the fixed base plate portion 11.
[0038] Please see Figure 9 and Figure 10 In the above embodiment, the fixed base plate portion 11 also has a notch 10d, which is recessed from the edge of the fixed base plate portion 11 towards the center and extends through the fixed base plate portion 11 along its thickness direction. The compressor includes a housing 6 and a connector 9. The inner wall of the housing 6 has a protrusion 61, which is at least partially located within the notch 10d. The connector 9 connects the exhaust cover 2 and the protrusion 61. During assembly, the protrusion 61 and the notch 10d cooperate to position the compressor. Then, the connector 9 connects and fixes the protrusion 61 and the exhaust cover 2. The exhaust cover 2 presses against the fixed scroll member 1. The notch 10d provides space for the connection between the connector 9 and the housing 6, and also reduces the weight of the fixed scroll member 1. Figure 10 The weight reduction tank 10a is not shown.
[0039] In the above embodiments, the outer casing assembly adopts a multi-stage casing, including a casing 6. A drive mechanism 7 is located within the casing 6. The drive mechanism 7 includes a motor 71 and a shaft 72. The motor 71 is connected to the shaft 72. The compressor also includes a support member 8, which is at least partially located within the casing 6. The shaft 72 passes through the support member 8 and is connected to the moving scroll member 5. Specifically, the stator of the motor 71 is connected to the casing 6. The shaft 72 has a body portion 721 and an eccentric portion 722. The eccentric portion 722 is eccentrically positioned relative to the central axis of the body portion 721. The rotor of the motor 71 is connected to the body portion 721, and the eccentric portion 722 is connected to the moving scroll member 5. When the compressor compresses the refrigerant, the motor 71 is energized. Under the action of the magnetic field, the rotor of the motor 71 rotates, driving the shaft 72 to rotate. Because the eccentric portion 722 of the shaft 72 is eccentrically positioned relative to the body portion 721, the shaft 72 drives the moving scroll member 5 to perform planar motion relative to the stationary scroll member 1. The housing 6 has an air inlet 60. The refrigerant in the heat exchange system pipeline enters the compressor through the air inlet 60 and enters the suction chamber LP. As the moving scroll 5 moves relative to the fixed scroll 1, the refrigerant is drawn from the suction chamber LP into the compression chamber P. It is compressed from the outermost middle compression chamber P2 to the innermost central compression chamber P1. The main exhaust port O1 and the auxiliary exhaust port O2 can communicate with the exhaust chamber HP. When the gas pressure in the central compression chamber P1 connected to the main exhaust port O1 is greater than the exhaust pressure of the main valve plate 31a, the gas pressure causes the main valve plate 31a to open, and the refrigerant in the central compression chamber P1 is discharged from the main exhaust port O1 to the exhaust chamber HP. Similarly, when the gas pressure in the intermediate compression chamber P2 connected to the auxiliary exhaust port O2 is greater than the exhaust pressure of the auxiliary valve plate 32a, the gas pressure causes the auxiliary valve plate 32a to open, and the gas in the intermediate compression chamber P2 connected to the auxiliary exhaust port O2 is discharged from the auxiliary exhaust port O2 to the exhaust chamber HP; otherwise, the exhaust port is closed. The exhaust cover 2 has an outlet 20, and the refrigerant entering the exhaust chamber HP is finally discharged from the compressor through the outlet 20 and enters the heat exchange system for heat exchange.
[0040] In the above embodiment, the weight reduction groove 10a extends along the edge of the fixed base plate portion 11 in the length direction, but does not extend to the edge of the fixed base plate portion 11, so that the fixed base plate portion 11 has a continuous plane at the edge of the second end face 11a2 to provide a sealing member 4 and an exhaust cover 2 for sealing.
[0041] Some of the technical implementation methods described above can be combined or replaced.
[0042] The technical principles of this application have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this application that can be conceived by those skilled in the art without creative effort will fall within the scope of protection of this application.
