[0043] 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0044] Hereinafter, with reference to the accompanying drawings, a stator core 2 of a compressor according to an embodiment of the present utility model will be described.

[0045] like Figure 1-Figure 7 As shown, according to the stator core 2 of the compressor of the embodiment of the utility model, the outer peripheral wall of the stator core 2 is provided with a concave first guide groove 21, and the axial extension direction of the first guide groove 21 forms an angle with the extension direction of the axial center axis W of the stator core 2.

[0046] In this way, the extension direction of the first guide groove 21 can correspond to the flow path of the refrigerant, thereby improving the guiding effect of the first guide groove 21 on the refrigerant, which is beneficial to reducing flow resistance and noise, and can also extend the flow path, increase the contact area between the stator core 2 and the refrigerant, and improve the cooling effect of the refrigerant.

[0047] First, if Figure 1-Figure 3 As shown, the compressor 100 includes a housing 1, a stator core 2 and a rotor core 3. The stator core 2 is mounted on the outer side of the rotor core 3, and the stator core 2 and the rotor core 3 are used to be installed together in the housing 1. The outer peripheral wall of the stator core 2 is suitable for being supported on the inner side wall of the housing 1 to be connected to the housing 1. A guide channel is formed between the housing 1 and the stator core 2, and the guide channel is used to guide the flow of the refrigerant.

[0048] Specifically, when the compressor 100 is running, the refrigerant can flow into the compressor 100, and the refrigerant will rotate and flow into the guide channel. When flowing through the guide channel, the refrigerant can cool the stator core 2 and the housing 1. Then, the refrigerant can flow to the stator core 2 and the rotor core 3 and be compressed.

[0049] Among them, a first guide groove 21 can be provided on the outer peripheral wall of the stator core 2, and the first guide groove 21 is recessed inwardly along the radial direction of the stator core 2, and the first guide groove 21 is suitable for defining at least part of the guide channel with the inner peripheral wall of the shell 1. The axial extension direction of the first guide groove 21 and the extension direction of the axial center axis W of the stator core 2 have an angle, so that the first guide groove 21 can correspond to the flow path of the refrigerant. Through the above-mentioned arrangement, the guiding effect of the first guide groove 21 on the refrigerant can be improved, the flow stability of the refrigerant can be improved, the flow resistance can be reduced, and noise can be eliminated. In addition, the inclined first guide groove 21 has a longer flow path, which is conducive to improving the cooling effect of the refrigerant on the stator core 2.

[0050] According to the stator core 2 of the compressor of the embodiment of the utility model, an angle is formed between the axial extension direction of the first guide groove 21 and the extension direction of the axial center axis W of the stator core 2, so that the extension direction of the first guide groove 21 can correspond to the flow path of the refrigerant, thereby improving the guiding effect of the first guide groove 21 on the refrigerant, which is beneficial to reducing flow resistance and noise, and can extend the flow path of the refrigerant, increase the contact area between the stator core 2 and the refrigerant, and improve the cooling effect of the refrigerant.

[0051] In some embodiments of the present invention, Figure 3-Figure 4 As shown, the inclination angle of the first guide groove 21 relative to the axial center axis W can be set to α1, satisfying: 0°<α1≤20°. For example, the inclination angle α1 of the first guide groove 21 relative to the axial center axis W can be set to 5°; or, the inclination angle α1 of the first guide groove 21 relative to the axial center axis W can be set to 10°; or, the inclination angle α1 of the first guide groove 21 relative to the axial center axis W can be set to 15°, and this application does not limit this.

[0052] Through the above arrangement, the guiding effect of the first guide groove 21 can be ensured, and the difficulty of processing the first guide groove 21 can be reduced, thereby improving the design rationality of the stator core 2.

[0053] More preferably, the stator core 2 may be arranged to satisfy: 10°≤α1≤20°.

[0054] Of course, the present application is not limited thereto, and the angle α1 of the axial extension direction of the first guide groove 21 relative to the extension direction of the axial central axis W can be set to 30°, 40°, 50°, 60°, 70°, 80°, etc., so that the first guide groove 21 can be formed into a spiral shape. In this way, the flow path can be further extended to improve the cooling effect of the refrigerant.

[0055] In some embodiments of the present invention, the inner diameter of the stator core 2 is d0, the outer diameter of the stator core 2 is d1, and the circumferential width of the first guide groove 21 is W0, satisfying: 1.55d0≤d1≤1.65d0, 0.2d0≤W0≤0.23d0.

[0056] For example, refer to Figure 5-Figure 6 As shown, the inner diameter of the stator core 2 can be set to d0, the outer diameter of the stator core 2 can be set to d1, and the circumferential width of the first guide groove 21 can be set to W0, satisfying: 1.55d0≤d1≤1.65d0, 0.2d0≤W0≤0.23d0.

[0057] For example, the outer diameter d1 of the stator core 2 can be taken as 1.58 times the inner diameter d0 of the stator core 2; or, the outer diameter d1 of the stator core 2 can be taken as 1.60 times the inner diameter d0 of the stator core 2; or, the outer diameter d1 of the stator core 2 can be taken as 1.62 times the inner diameter d0 of the stator core 2, and the present application does not impose any restrictions on this.

[0058] At the same time, the circumferential width W0 of the first guide groove 21 can be set to 0.21 times the inner diameter d0 of the stator core 2; or, the circumferential width W0 of the first guide groove 21 can be set to 0.215 times the inner diameter d0 of the stator core 2; or, the circumferential width W0 of the first guide groove 21 can be set to 0.22 times the inner diameter d0 of the stator core 2, and the present application does not impose any restrictions on this.

[0059] Through the above arrangement, the first guide groove 21 can have a sufficient circumferential width, which is beneficial to improving the guiding effect of the first guide groove 21, and can avoid the circumferential width of the first guide groove 21 being too large to affect the structural strength of the stator core 2, thereby improving the structural reliability of the stator core 2.

[0060] More preferably, the stator core 2 may be arranged to satisfy: 1.6d0≤d1≤1.65d0, 0.22d0≤W0≤0.23d0.

[0061] In some embodiments of the utility model, reference Figure 5 As shown, the stator core 2 includes a yoke 22 and a tooth 23, the tooth 23 is arranged on the inner peripheral wall of the yoke 22 and is protruded inwardly, the inner diameter of the yoke 22 is set to d2, and satisfies: 1.4d0≤d2≤1.5d0, such as the inner diameter d2 of the yoke 22 can be taken as 1.42d0, 1.45d0, 1.48d0, etc. Among them, the thickness of the yoke 22 is set to T1, T1 = (d1-d2) / 2, and the thickness of the tooth 23 is set to T2, and satisfies: 0.1d0≤d1≤0.12d0. Therefore, it is beneficial to improve the overall structural strength of the stator core 2.

[0062] In some embodiments of the present invention, referring to Figure 6 As shown, the circumferential width of the first guide groove 21 can be set to W0, and the maximum depth of the first guide groove 21 can be set to H, satisfying: 0.045W0≤H≤0.06W0. For example, the maximum depth H of the first guide groove 21 can be taken as 0.05 times the circumferential width W0 of the first guide groove 21; or, the maximum depth H of the first guide groove 21 can be taken as 0.055 times the circumferential width W0 of the first guide groove 21; or, the maximum depth H of the first guide groove 21 can be taken as 0.058 times the circumferential width W0 of the first guide groove 21, and this application does not limit this.

[0063] Through the above arrangement, the first guide groove 21 can have a suitable width-to-depth ratio, thereby improving the flow stability of the refrigerant in the first guide groove 21, and helping to reduce flow resistance and eliminate noise.

[0064] More preferably, the stator core 2 may be arranged to satisfy: 0.05W0≤H≤0.055W0.

[0065] In some embodiments of the present invention, Figure 6 As shown, the first guide groove 21 includes a plurality of sub-grooves 210, and the plurality of sub-grooves 210 are sequentially arranged along the circumferential direction of the stator core 2 and are interconnected. In other words, by setting the first guide groove 21 to include a plurality of sub-grooves 210, the width and depth of a single sub-groove 210 can be adjusted to carry out a targeted design of the first guide groove 21, which is conducive to improving the guiding effect of the first guide groove 21 on the refrigerant and reducing the processing difficulty of the first guide groove 21. Thus, the practicality of the stator core 2 can be improved.

[0066] In some embodiments of the present invention, Figure 6 As shown, the circumferential width of the first guide groove 21 can be set to W0, and the width of each sub-groove 210 can be set to W1, satisfying: 0.1W0≤W1≤0.3W0. For example, the width W1 of the sub-groove 210 can be set to 0.15W0, 0.2W0, 0.25W0, etc., and this application does not impose any restrictions on this.

[0067] Exemplarily, the first guide groove 21 can be set to include four sub-grooves 210, and the width W1 of each sub-groove 210 is 0.25W0; or, the first guide groove 21 can be set to include five sub-grooves 210, and the five sub-grooves 210 are respectively arranged in circumferential order. The width of the first sub-groove 211 and the fifth sub-groove 215 can be set to 0.3W0, the width of the second sub-groove 212 and the fourth sub-groove 214 can be set to 0.15W0, and the width of the third sub-groove 213 can be set to 0.1W0.

[0068] It is understandable that by limiting the width of the sub-slot 210 within the above-mentioned range, it is possible to avoid the width of the sub-slot 210 being too small to be difficult to process, and it is possible to avoid the width of the sub-slot 210 being too large to affect the arrangement of the first guide groove 21, thereby improving the design rationality of the stator core 2.

[0069] More preferably, the stator core 2 may be arranged to satisfy: 0.15W0≤W1≤0.25W0.

[0070] In some embodiments of the present invention, Figure 6As shown, in the circumferential direction of the stator core 2 , a plurality of sub-slots 210 may be arranged such that the depths thereof gradually increase from both sides to the middle.

[0071] Exemplarily, the first guide groove 21 can be set to include five sub-grooves 210, and the five sub-grooves 210 are respectively the first sub-groove 211, the second sub-groove 212, the third sub-groove 213, the fourth sub-groove 214 and the fifth sub-groove 215 arranged in circumferential order. The depth of the first sub-groove 211 (the fifth sub-groove 215) can be set to be greater than the depth of the second sub-groove 212 (the fourth sub-groove 214), and the depth of the second sub-groove 212 (the fourth sub-groove 214) can be set to be greater than the depth of the third sub-groove 213.

[0072] Through the above arrangement, the guiding effect of the first guide groove 21 can be improved, and the influence of the first guide groove 21 on the structural strength of the stator core 2 can be reduced, which is beneficial to improving the design rationality of the stator core 2.

[0073] It should be noted that the first guide groove 21 can be constructed as an axially symmetrical structure or an asymmetrical structure, and the present application does not impose any limitation on this.

[0074] In some embodiments of the utility model, a first chamfer may be provided at the connection of adjacent side walls of each sub-groove 210. For example, the first guide groove 21 may include a first sub-groove 211 and a second sub-groove 212, the depth of the first sub-groove 211 is less than the depth of the second sub-groove 212, and the bottom wall of the first sub-groove 211 may be connected to the side wall of the second sub-groove 212 through a first chamfer. In this way, the guiding effect of the first guide groove 21 can be improved.

[0075] In some embodiments of the utility model, second chamfers may be provided between the opposite side walls of the first guide groove 21 and the outer peripheral wall of the stator core 2. Through the above arrangement, during the assembly process, the stator core 2 can be prevented from scratching the operator or the housing 1, thereby improving the design rationality of the stator core 2.

[0076] In some embodiments of the utility model, adjacent sub-grooves 210 may be connected by a third chamfer. For example, the first guide groove 21 may include a first sub-groove 211 and a second sub-groove 212, the depth of the first sub-groove 211 is less than the depth of the second sub-groove 212, and the bottom wall of the first sub-groove 211 may be directly connected to the bottom wall of the second sub-groove 212 by a third chamfer. Thus, the inner wall of the first guide groove 21 may be made smoother, the flow stability of the refrigerant in the first guide groove 21 is improved, and noise is reduced.

[0077] The utility model also provides a compressor 100 .

[0078] like Figure 1As shown, the compressor 100 according to the embodiment of the present utility model comprises: a housing 1 and a stator core 2 . The stator core 2 is the stator core 2 according to any of the above embodiments, and the stator core 2 is disposed in the housing 1 .

[0079] According to the compressor 100 of the embodiment of the utility model, an angle is set between the axial extension direction of the first guide groove 21 and the extension direction of the axial center axis W of the stator core 2, so that the extension direction of the first guide groove 21 can correspond to the flow path of the refrigerant, thereby improving the guiding effect of the first guide groove 21 on the refrigerant, which is beneficial to reducing flow resistance and noise, and can extend the flow path of the refrigerant, increase the contact area between the stator core 2 and the refrigerant, improve the cooling effect of the refrigerant, and improve the overall performance of the compressor 100.

[0080] 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, smaller overall structural dimensions, and a smoother energy conversion process.

[0081] In some embodiments of the utility model, the shell 1 includes a shell body 11 and a plurality of bosses 12, the shell body 11 is provided with a mounting cavity 111, the plurality of bosses 12 are spaced apart on the inner circumferential wall of the mounting cavity 111 and protrude inwardly, and a second guide groove 13 is defined between any two adjacent bosses 12; the stator core 2 is disposed in the mounting cavity 111 and contacts the boss 12, and in the radial direction of the stator core 2, the first guide groove 21 and the second guide groove 13 are radially oppositely arranged to be connected.

[0082] For example, refer to Figure 1-Figure 2 As shown, the shell 1 includes a shell body 11, which is cylindrical in shape. An installation cavity 111 with one end open is provided in the shell body 11, and the stator core 2 is matched with the installation cavity 111 so that the stator core 2 can be installed in the installation cavity 111.

[0083] The housing 1 further includes a plurality of bosses 12, which are arranged at the inner peripheral wall of the mounting cavity 111 and are spaced apart along the circumference of the housing body 11. The bosses 12 are arranged to protrude inwardly along the radial direction of the housing body 11, and the plurality of bosses 12 are respectively supported at the outer peripheral wall of the stator core 2 to be limitedly matched with the stator core 2. A second guide groove 13 is defined between any two adjacent bosses 12, and in the radial direction of the stator core 2, the first guide groove 21 and the second guide groove 13 are arranged radially opposite to each other, so that the first guide groove 21 and the second guide groove 13 can be connected to form a guide channel.

[0084] It can be understood that by setting the first guide groove 21 and the second guide groove 13 to be connected, the first guide groove 21 can guide the refrigerant in the second guide groove 13, which is beneficial to improve the guiding effect of the first guide groove 21 and improve the design rationality of the compressor 100.

[0085] In some embodiments of the present invention, Figure 7 As shown, there is an angle α2 between the axial extension direction of each boss 12 and the extension direction of the axial center axis W, so that there is an angle α2 between the axial extension direction of the second guide groove 13 defined by two adjacent bosses 12 and the extension direction of the axial center axis W, so that the axial extension direction of the second guide groove 13 and the axial extension direction of the first guide groove 21 tend to be parallel.

[0086] Through the above arrangement, the first guide groove 21 and the second guide groove 13 can jointly guide the refrigerant, which is beneficial to reduce flow resistance, reduce noise, and can extend the flow path of the refrigerant, increase the contact area between the stator core and the refrigerant, and improve the cooling effect of the refrigerant.

[0087] In some embodiments of the present invention, Figure 2 As shown, the boss 12 can be arranged in parallel with the first guide groove 21, so that the second guide groove 13 defined by two adjacent bosses 12 can remain parallel to the first guide groove 21. As a result, the first guide groove 21 and the second guide groove 13 can jointly guide the refrigerant, thereby improving the guiding effect of the first guide groove 21 and the second guide groove 13 on the refrigerant, which is conducive to reducing flow resistance, reducing noise, and improving the practicality of the compressor 100.
