[0011] According to an embodiment of the compressor of the present invention, the support portion includes: a first connecting section, one end of which is connected to the fixing portion, and the other end of which extends toward the liquid reservoir; and a limiting section, which is connected to the other end of the first connecting section and engages with the outer wall surface of the liquid reservoir.

[0012] In some examples, the compressor further includes a clamp, and the support further includes a second connecting section, one end of which is connected to the limiting section, and the other end of which extends away from the reservoir, the clamp cooperating with the second connecting section to clamp the reservoir.

[0013] In some examples, the band has a snap-fit ​​portion, the second connecting segment has a mating portion, and the snap-fit ​​portion engages with the mating portion; and / or, the band has a first connecting hole, the second connecting segment has a second connecting hole, and the first connecting hole and the second connecting hole are connected by a fastener.

[0014] In some examples, the limiting segment is welded to the reservoir.

[0015] In some examples, it also includes: reinforcing ribs, which are disposed on both sides of the first connecting segment and are fixedly connected to the first connecting segment and the fixing part, respectively.

[0016] In some examples, the bracket is a one-piece molded part.

[0017] According to an embodiment of the compressor, the fixing part is welded to the compressor body, and the fixing position is a weld point.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The following is for reference. Figures 1-4 A compressor 100 according to an embodiment of the present invention is described.

[0032] like Figures 1-4 As shown, a compressor 100 according to an embodiment of the present invention includes: a compressor body 10, a liquid receiver 20, and a support 30. The liquid receiver 20 is in communication with the compressor body 10, and the maximum diameter of the liquid receiver 20 is D1. The support 30 is disposed between the compressor body 10 and the liquid receiver 20, and the support 30 extends along a direction perpendicular to the arrangement direction of the liquid receiver 20 and the compressor body 10 (e.g., along...). Figure 1 (as shown in the left and right directions), and the extension direction of the bracket 30 is perpendicular to the axis of the compressor body 10.

[0033] The bracket 30 includes a fixing part 31 and a supporting part 32. The fixing part 31 is used to connect with the compressor body 10, and the two are fixedly connected by a plurality of fixing positions 311. The maximum distance between the plurality of fixing positions 311 in the extension direction of the bracket 30 is W. It can be understood that when there are two fixing positions 311, the distance between the two fixing positions 311 in the extension direction of the bracket 30 is W. When there are more than one fixing position 311, the maximum distance between any two fixing positions 311 in the extension direction of the bracket 30 is W.

[0034] The support part 32 includes two parts. In the extension direction of the bracket 30, the two support parts 32 are located at both ends of the fixing part 31 respectively. The two support parts 32 abut against the liquid reservoir 20 respectively, and the support parts 32 can realize the function of supporting the liquid reservoir 20.

[0035] In this structure, the fixing position 311 of the fixing part 31 and the supporting part 32 roughly form a cantilever beam structure. The applicant discovered that, in order to ensure reliable engagement between the bracket 30 and the compressor body 10 and the liquid receiver 20, the length of the bracket 30 (i.e., the dimension in the extending direction of the bracket 30) needs to be within an appropriate range. The larger the maximum distance between the multiple fixing positions 311, the shorter the cantilever beam and the stronger the support rigidity. However, if the maximum distance between the multiple fixing positions 311 is too large, it will affect the arrangement of the fixing part 31 between the compressor body 10 and the liquid receiver 20. Therefore, the applicant, through practical... The verification analysis limits the W / D1 value to be greater than 0.22 and less than 0.24, for example, W / D1 is 0.23, 0.235, etc., or W / D1 is equal to 0.22, or W / D1 is equal to 0.24. When W / D1 meets the above relationship, the support rigidity can be enhanced, the rigidity of the connection system between the liquid receiver 20 and the compressor body 10 can be increased, the low-order natural frequency of the liquid receiver 20 can be increased, and the low-frequency resonance of the liquid receiver 20 can be avoided, thereby reducing the overall vibration of the compressor and reducing noise. At the same time, there is no need to add additional reinforcing structures and increase the structural size, thus avoiding the increase in manufacturing costs.

[0036] According to the compressor 100 of the present invention, by designing the spacing of the fixing position 311 and the size of the liquid receiver 20, the position of the fixing position 311 is defined. This can enhance the support rigidity, improve the rigidity of the connection system between the liquid receiver 20 and the compressor body 10, and increase the low-order natural frequency of the liquid receiver 20, thereby avoiding low-frequency resonance of the liquid receiver 20, which in turn reduces the vibration of the compressor 100, lowers the noise, and avoids the increase in cost.

[0037] like Figure 1 As shown, in some specific examples, the liquid receiver 20 and the compressor body 10 are arranged in a front-to-back direction, and the center line connecting the compressor body 10 and the liquid receiver 20 extends in a front-to-back direction. The bracket 10 extends in a direction perpendicular to the center line connecting the compressor body 10 and the liquid receiver 20. The fixing part 31 forms an arc-shaped plate extending circumferentially along the compressor body 10. The two support parts 32 are respectively arranged on opposite sides of the center line connecting the compressor body 10 and the liquid receiver 20. The two support parts 32 can be arranged symmetrically. The fixing positions 311 on the fixing part 31 can be arranged symmetrically with respect to the center line connecting the compressor body 10 and the liquid receiver 20. Of course, multiple fixing positions 311 can also be arranged asymmetrically with respect to the center line connecting the compressor body 10 and the liquid receiver 20, so that the fixing positions 311 and the compressor body 10 do not interfere with each other and are easy to cooperate.

[0038] like Figure 1As shown, according to some embodiments of the present invention, based on satisfying the spacing between the fixing positions 311 and the size of the reservoir 20, if the maximum spacing between the multiple fixing positions 311 is small, the compressor body 10 is prone to tangential vibration when the fixing part 31 is engaged with the compressor body 10, which will also generate a large noise. If the maximum spacing between the multiple fixing positions 311 is too large, interference is likely to occur when the fixing part 31 is engaged with the compressor body 10, and unnecessary costs will be increased. Therefore, the applicant has limited the ratio of the maximum spacing to the maximum diameter D2 of the compressor body 10 through experimental analysis. W / D2 is greater than 0.17 and less than 0.20, for example, W / D2 equals 0.18, 0.19, or W / D2 equals 0.17, or W / D2 equals 0.20. When W / D2 satisfies the above relationship, the fixing stiffness of the bracket can be further improved, and the tangential vibration of the compressor body 10 can be avoided, further reducing the overall vibration of the compressor 100 and reducing noise.

[0039] According to some embodiments of the present invention, the bracket 30 extends in a left-right direction, the extension direction being the length direction, and in a direction perpendicular to the extension direction of the bracket 30 (e.g., Figure 2 In the vertical direction shown, at least one side of the fixing part 31 protrudes from the supporting part 32. This direction is the width direction, that is, the width of the supporting part 32 is less than the width of the fixing part 31. On the cantilever beam structure formed by the bracket 30, the size of the cantilever beam can be further reduced, thereby achieving the purpose of improving the support stiffness. In other words, this can reduce the structural size and reduce the cost while improving the fixing stiffness of the bracket.

[0040] like Figure 2 and Figure 3 As shown, in some examples, the upper and lower sides of the fixing part 31 protrude from the upper and lower sides of the supporting part 32, and the bracket 30 roughly forms a cross-shaped structure. This further reduces the structural size and lowers the cost while ensuring the support rigidity.

[0041] like Figure 3 As shown, in some specific examples, in the extension direction perpendicular to the support 30 (e.g. Figure 3 In the vertical direction shown, the length of the fixing part 31 is L1, and the maximum distance between multiple fixing positions 311 is H. H / L1 is equal to 0.8, or H / L1 is greater than 0.8, for example, H / L1 is equal to 0.88, 0.9, etc. When H / L1 satisfies the above relationship, the support rigidity can be enhanced, the rigidity of the connection system between the liquid reservoir 20 and the compressor body 10 can be improved, thereby reducing the overall vibration of the compressor and reducing noise. At the same time, there is no need to add additional reinforcing structures and increase the structural size, thus avoiding the increase in manufacturing costs.

[0042] like Figure 3As shown, in some specific examples, in the extension direction perpendicular to the support 30 (e.g. Figure 3 In the vertical direction shown, the length of the support part 32 is L2. If H / L2 is too small, it will easily affect the stability of the support part 32 and thus affect the support rigidity. Therefore, H / L2 is limited to be equal to 1.1 or greater than 1.1, for example, H / L2 is equal to 1.2, 1.25, etc. When H / L2 satisfies the above relationship, the support rigidity can be enhanced, the rigidity of the connection system between the liquid receiver 20 and the compressor body 10 can be increased, the low-order natural frequency of the liquid receiver 20 can be increased, and the low-frequency resonance of the liquid receiver 20 can be avoided. This reduces the overall vibration of the compressor and lowers the noise. At the same time, there is no need to add additional reinforcing structures and increase the structural size, thus avoiding the increase in manufacturing costs.

[0043] like Figures 1-4 As shown, according to some embodiments of the present invention, the fixing part 31 is disposed in close contact with the compressor body 10, and the support part 32 extends as a whole toward the liquid reservoir 20. Specifically, the support part 32 includes a first connecting section 321 and a limiting section 322. One end of the first connecting section 321 is connected to the fixing part 31, and the other end of the first connecting section 321 extends toward the liquid reservoir 20. The limiting section 322 is connected to the other end of the first connecting section 321, and the limiting section 322 cooperates with the outer wall surface of the liquid reservoir 20. The limiting section 322 can extend tangentially along the liquid reservoir 20, and the limiting section 322 can also extend circumferentially along the liquid reservoir 20 to improve the reliability of the cooperation between the limiting section 322 and the outer wall surface of the liquid reservoir 20.

[0044] The fitting method here can be a butt joint fitting, which is fixed by other structural components, or the fitting method here is a fastening connection such as welding.

[0045] It is understandable that the two limiting segments 322 of the two support parts 32 are symmetrically arranged on both sides of the radial direction of the liquid reservoir 20. Thus, the two limiting segments 322 can effectively support the liquid reservoir 20. Under the constraint of the relationship between the fixed position 311 and the radial dimension of the liquid reservoir 20, the low-order natural frequency of the liquid reservoir 20 is increased, low-frequency resonance of the liquid reservoir 20 is avoided, thereby reducing the overall vibration of the compressor and reducing noise.

[0046] like Figure 1As shown, in some examples, the compressor 100 also includes a clamp 40, and the support 32 further includes a second connecting section 322. One end of the second connecting section 322 is connected to the limiting section 322, and the other end of the second connecting section 322 extends away from the liquid reservoir 20. The clamp 40 cooperates with the second connecting section 322, thereby allowing the clamp 40 to tighten around the liquid reservoir 20 while preventing interference between the fixed end of the clamp 40 and the liquid reservoir 20. Of course, a rubber sheet can be provided between the clamp 40 and the liquid reservoir 20, which can improve the reliability of the cooperation between the clamp 40 and the liquid reservoir 20, and reduce vibration and noise.

[0047] like Figures 1-4 As shown, in some specific examples, the hoop 40 has a snap-fit ​​portion, and the second connecting section 322 of a support portion 32 has a mating portion 324. By snapping the snap-fit ​​portion and mating portion 324 together, the hoop 40 can be easily positioned and installed on the bracket 30.

[0048] In some specific examples, the clamp 40 has a first connecting hole, and the second connecting section 322 of the other support 32 has a second connecting hole 325. The first connecting hole and the second connecting hole 325 are fixedly connected by fasteners, thereby achieving a tight connection between the clamp 40 and the bracket 30 and ensuring the reliability of the liquid reservoir 20. The fasteners here can be screws, bolts, etc. In this case, the clamp 40 fixes the liquid reservoir 20 to the bracket 30 with a rubber sheet, which can also reduce the risk of fastener stripping.

[0049] In some specific examples, the limiting segment 322 is welded to the reservoir 20, and the reservoir 20 is fixed by directly welding it to the limiting segment 322.

[0050] In some specific examples, the support 32 includes a first connecting section 321, a limiting section 322, and a second connecting section 323. The reservoir 20 is welded to the limiting section 322, and the clamp 40 is fixedly connected to the second connecting section 323, thereby achieving double fixation of the reservoir 20, which can further improve the fixation effect of the reservoir 20 and reduce the vibration of the reservoir 20.

[0051] like Figure 2 and Figure 3 As shown, in some examples, the bracket 30 further includes a reinforcing rib 33. The upper and lower sides of the fixing part 31 protrude from the supporting part 31, and the reinforcing rib 33 is disposed on the upper and lower sides of the first connecting section 321. The reinforcing rib 33 is fixedly connected to the first connecting section 321 and the fixing part 31, respectively. This can further increase the support rigidity, improve the rigidity of the connection system between the liquid receiver 20 and the compressor body 10, increase the low-order natural frequency of the liquid receiver 20, avoid low-frequency resonance of the liquid receiver 20, and thus reduce the overall vibration of the compressor and reduce noise.

[0052] Of course, when the support part 31 protrudes from one side of the fixing part 31, the reinforcing rib 33 is provided on that side of the first connecting section 321, thereby fixing one side of the first connecting section 321 to the fixing part 31.

[0053] According to some embodiments of the present invention, the bracket 30 is an integrally formed part, that is, the fixing part 31 and the supporting part 32 are integrally formed, and the reinforcing rib 33 is also integrally formed on the fixing part 31 and the supporting part 32. This can further improve the strength of the structure, thereby improving the overall support stiffness, avoiding low-frequency resonance of the liquid reservoir 20, and reducing vibration and noise.

[0054] like Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the fixing part 31 is welded to the compressor body 10. The fixing position 311 is a weld point. The weld point can be a protrusion, a raised point, a raised rib, etc., or it can be a through hole, or it can be a recess, a seam, a groove, etc., specifically limited according to the welding form.

[0055] An electrical device according to an embodiment of the present invention includes a compressor 100 according to an embodiment of the present invention. By using the compressor 100, the low-order natural frequency of the compressor 100 can be increased, the overall vibration of the compressor 100 can be reduced, and the noise can be reduced.

[0056] The following is combined Figures 1-4 A specific embodiment of the compressor 100 according to the present invention is described.

[0057] The compressor 100 includes a compressor body 10, a liquid receiver 20, a bracket 30, and a clamp 40. The liquid receiver 20 is connected to the compressor body 10. The bracket 30 is disposed between the compressor body 10 and the liquid receiver 20. The bracket 30 includes a fixing part 31 and two supporting parts 32. The maximum diameter of the liquid receiver 20 is D1, and the maximum diameter of the compressor body 10 is D2. The fixing part 31 is welded to the compressor body 10, and the weld points form a fixing position 311. Figure 3 As shown, the fixing part 31 has four fixing positions 311, and the maximum distance between all fixing positions 311 in the left and right directions is W, W / D1=0.23, W / D2=0.17.

[0058] The support portion 32 includes a first connecting section 321, a limiting section 322, and a second connecting section 322. One end of the first connecting section 321 is connected to the fixing portion 31, and the other end of the first connecting section 321 extends toward the reservoir 20. The limiting section 322 is connected to the other end of the first connecting section 321 and mates with the outer wall surface of the reservoir 20. One end of the second connecting section 322 is connected to the limiting section 322, and the other end of the second connecting section 322 extends away from the reservoir 20. The second connecting section 322 of one support portion 32 has a mating portion 324, and the second connecting section 322 of the other support portion 32 has a second connecting hole 325. One end of the clamp 40 has a snap-fit ​​portion, and the other end of the clamp 40 has a first connecting hole. The snap-fit ​​portion engages with the mating portion 324. The first connecting hole and the second connecting hole 325 are fixedly connected by fasteners, thereby achieving a tight connection between the clamp 40 and the bracket 30.

[0059] The upper and lower surfaces of the fixing part 31 protrude from the upper and lower surfaces of the limiting section 322 of the support part 32, respectively. The distance between the upper and lower surfaces of the fixing part 31 is L1, the distance between the upper and lower surfaces of the limiting section 322 is L2, and the maximum distance between all the fixing positions 311 in the vertical direction is H, where H / L = 0.80 and H / L2 = 1.2.

[0060] Through experimental analysis, the tangential first-order natural frequency of the compressor receiver according to the embodiment of the present invention is 421Hz, which is much larger than the 237Hz first-order natural frequency of the compressor receiver in the prior art. Simultaneously, the average rotational vibration of the receiver at 60Hz is 5.0, with a maximum value of 5.6, and the average rotational vibration at 90Hz is 7.7, with a maximum value of 8.1. Compared to the average rotational vibration of 9.9 in the prior art, the average rotational vibration of the receiver is reduced by 2.2 m / s². 2 Clearly, the compressor 100 of this embodiment of the invention achieves the effect of reducing vibration, and tests have shown that the noise is significantly reduced, thus achieving the effect of noise reduction.

[0061] Other configurations and operations of the compressor 100 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here. The vertical, horizontal, and front-back directions are defined as shown in the figures.

[0062] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features not in direct contact but through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
