For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] Hereinafter, a compressor 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] like Figure 1-Figure 6 As shown, the compressor 100 according to the embodiment of the utility model includes: a housing assembly 1, a scroll assembly 2 and a bracket 3, the housing assembly 1 is provided with a first oil storage chamber 121; the scroll assembly 2 includes a first scroll 21, and the scroll assembly 2 is arranged on the housing assembly 1; the bracket 3 is arranged on the housing assembly 1, and the bracket 3 and the first scroll 21 are in sliding contact with each other, and the end surface of the bracket 3 facing the first scroll 21 is provided with a lubrication groove 31, and the first inlet 311 of the lubrication groove 31 is connected to the first oil storage chamber 121.

[0048] Thus, the lubricating oil in the first oil storage chamber 121 can flow into the lubrication groove 31 to fully lubricate the friction surface between the first scroll 21 and the bracket 3, which is beneficial to reduce the wear of the first scroll 21 and the bracket 3 and increase the service life of the compressor 100.

[0049] First, if Figure 1-Figure 2As shown, the compressor 100 includes a housing assembly 1, a scroll assembly 2 and a bracket 3. The housing assembly 1 is suitable for defining an installation space. The scroll assembly 2 and the bracket 3 are both installed in the installation space. The scroll assembly 2 is sandwiched between the bracket 3 and the end of the housing assembly 1. The side of the bracket 3 facing away from the scroll assembly 2 defines a suction cavity 13 with the housing assembly 1. The housing assembly 1 is also provided with a first oil storage cavity 121, and the first oil storage cavity 121 is used to store lubricating oil.

[0050] The scroll assembly 2 includes a first scroll 21 and a second scroll 22. The first scroll 21 is arranged on a side of the second scroll 22 close to the bracket 3. The first scroll 21 is limitedly matched with the bracket 3 along the axial direction to prevent the first scroll 21 from moving. The first scroll 21 is slidable relative to the end surface of the bracket 3, so that the first scroll 21 can move relative to the second scroll 22, so that the scroll assembly 2 can inhale the refrigerant from the suction chamber 13 and compress it, and after the compression is completed, the scroll assembly 2 can discharge the compressed refrigerant outward. It should be noted that the second scroll 22 can be a fixed scroll, and the first scroll 21 can be a movable scroll.

[0051] Among them, a lubrication groove 31 can be provided on the end surface of the bracket 3 facing the first scroll 21, and the lubrication groove 31 is provided with a first inlet 311, and the first inlet 311 is connected to the bottom of the first oil storage chamber 121, so that the lubricating oil in the first oil storage chamber 121 can flow into the lubrication groove 31 and be used to fully lubricate the friction surface between the bracket 3 and the first scroll 21. In this way, the wear of the first scroll 21 and the bracket 3 can be reduced, and the service life of the compressor 100 can be increased.

[0052] In actual settings, the width of the lubrication groove 31 can be set to 1 mm-2 mm, such as 1.2 mm, 1.5 mm, 1.8 mm, etc., and the depth of the lubrication groove 31 can be set to 2 mm-3 mm, such as 2.2 mm, 2.5 mm, 2.8 mm, etc. In this way, it can be ensured that the lubricating oil in the lubrication groove 31 has a sufficient flow rate, and it can be avoided that the size of the lubrication groove 31 is too large to affect the structural strength of the bracket 3.

[0053] According to the compressor 100 of the embodiment of the utility model, a lubrication groove 31 is provided on the end face of the bracket 3 facing the first scroll 21, and the first inlet 311 of the lubrication groove 31 is connected to the first oil storage chamber 121, so that the lubricating oil in the first oil storage chamber 121 can flow into the lubrication groove 31, so as to fully lubricate the friction surface between the first scroll 21 and the bracket 3, which is beneficial to reduce the wear of the first scroll 21 and the bracket 3 and increase the service life of the compressor 100.

[0054] In some embodiments of the utility model, the first oil storage chamber 121 is connected to the exhaust port 221 of the scroll assembly 2, a back pressure chamber 41 is defined between the bracket 3 and the first scroll 21, and the first outlet 312 of the lubrication groove 31 is connected to the back pressure chamber 41; the compressor 100 also includes a drive shaft 5, the first end portion 51 of the drive shaft 5 passes through the bracket 3 and cooperates with the first scroll 21, and the first end portion 51 of the drive shaft 5 is located in the back pressure chamber 41.

[0055] For example, refer to Figure 1 and Figure 2 As shown, the first oil storage chamber 121 is connected to the exhaust port 221 of the scroll assembly 2, so that the scroll assembly 2 can discharge the compressed refrigerant into the first oil storage chamber 121, so that the lubricating oil carried by the refrigerant can flow into the first oil storage chamber 121. The bracket 3 and the first scroll 21 define a back pressure chamber 41, and the first outlet 312 of the lubrication groove 31 is connected to the back pressure chamber 41, so that the lubricating oil in the lubrication groove 31 can flow into the back pressure chamber 41 through the first outlet 312, and the back pressure chamber 41 is connected to the compression chamber of the scroll assembly 2, and the lubricating oil flowing into the back pressure chamber 41 can flow into the scroll assembly 2, and be discharged into the first oil storage chamber 121 with the compressed refrigerant, thereby realizing the circulation of the lubricating oil.

[0056] In addition, the compressor 100 also includes a drive shaft 5, which is constructed as a crankshaft. The drive shaft 5 is installed in the suction chamber 13. The first end 51 of the drive shaft 5 can pass through the bracket 3 to cooperate with the first scroll 21. The first end 51 of the drive shaft 5 is located in the back pressure chamber 41. A main bearing 53 is provided between the first end 51 and the bracket 3, so that the drive shaft 5 can rotate relative to the bracket 3 to drive the first scroll 21 to move relative to the second scroll 22, thereby realizing compression of the refrigerant.

[0057] It can be understood that the lubricating oil flowing into the back pressure chamber 41 can fully lubricate the main bearing 53 to improve the rotation smoothness of the drive shaft 5, thereby improving the reliability of the compressor 100.

[0058] In some embodiments of the present invention, Figure 3 As shown, the lubrication groove 31 is formed as an annular structure, so that the lubrication groove 31 can fully cooperate with the first scroll 21 along the circumferential direction, so that the lubricating oil in the lubrication groove 31 can fully lubricate the friction surface between the bracket 3 and the first scroll 21, thereby greatly reducing the wear of the bracket 3 and the first scroll 21.

[0059] At the same time, if Figure 3As shown, the first inlet 311 and the first outlet 312 may be provided to form a long strip groove, the first inlet 311 extends outwardly along the radial direction of the lubricating groove 31 and the outer end thereof is communicated with the first oil storage chamber 121, and the first outlet 312 extends inwardly along the radial direction of the lubricating groove 31 and the inner end thereof is communicated with the back pressure chamber 41. Specifically, after the lubricating oil in the first oil storage chamber 121 flows into the first inlet 311, the lubricating oil may flow into the lubricating groove 31 along the first inlet 311, the lubricating oil may flow along the lubricating groove 31 to flow into the first outlet 312, and then flow out from the first outlet 312 into the back pressure chamber 41.

[0060] Through the above arrangement, the lubricating oil can be guided to improve the stability of the lubricating oil when it flows into or out of the lubricating groove 31, which is beneficial to improving the lubrication effect.

[0061] It should be noted that the first outlet 312 and the first inlet 311 can be respectively located on both sides of the lubrication groove 31 in the radial direction, so that the lubricating oil in the lubrication groove 31 is more uniform, which is conducive to improving the lubrication effect. Of course, the present application is not limited to this, and the first outlet 312 and the first inlet 311 can also be arranged adjacent to each other and separated, so that the lubricating oil flowing into the first inlet 311 needs to flow through the entire lubrication groove 31 before flowing into the first outlet 312.

[0062] In some embodiments of the present invention, the depth of the lubrication groove 31 is greater than the depth of the first inlet 311, and the depth of the lubrication groove 31 is greater than the depth of the first outlet 312. Through the above arrangement, part of the lubricating oil can always remain in the lubrication groove 31 to avoid the lubricating oil completely flowing out and causing direct friction between the bracket 3 and the first scroll 21, thereby improving the reliability of the lubrication groove 31.

[0063] In some embodiments of the present invention, the compressor 100 also includes a motor component 6 disposed in the housing assembly 1, a cooling oil channel 111 is provided between the motor component 6 and the inner wall of the housing assembly 1, and a second inlet 1111 of the cooling oil channel 111 is connected to the back pressure chamber 41.

[0064] For example, refer to Figure 1 As shown, the compressor 100 also includes a motor component 6, which is arranged in the installation space of the housing assembly 1. The motor component 6 includes a stator 61 and a mover 62. The stator 61 is sleeved on the outside of the mover 62 and the outer peripheral wall is supported on the inner peripheral wall of the main housing 11. The mover 62 is connected to the drive shaft 5 to drive the drive shaft 5 to rotate. At the same time, a cooling oil channel 111 can be provided between the outer peripheral wall of the stator 61 and the inner wall of the main housing 11. The cooling oil channel 111 has a second inlet 1111, and the second inlet 1111 is connected to the back pressure chamber 41, so that at least part of the lubricating oil flowing into the back pressure chamber 41 can flow into the cooling oil channel 111 to cool the motor component 6. In this way, the working reliability of the compressor 100 can be improved.

[0065] In some embodiments of the present invention, a support groove 112 is provided on the inner wall of the housing assembly 1 , the second end 52 of the drive shaft 5 is rotatably supported in the support groove 112 , and the second outlet 1112 of the cooling oil channel 111 is connected to the support groove 112 .

[0066] For example, refer to Figure 1 As shown, a support groove 112 may be provided on the inner wall of the main housing 11, and a secondary bearing 54 may be provided in the support groove 112. The second end portion 52 of the drive shaft 5 is used to extend into the support groove 112 and be supported on the secondary bearing 54, so that the drive shaft 5 is rotatably supported in the support groove 112. The cooling oil channel 111 is provided with a second outlet 1112, and the second outlet 1112 is connected to the support groove 112 through the guide channel 113, so that the lubricating oil flowing into the cooling oil channel 111 can flow into the support groove 112 through the second outlet 1112, so that the lubricating oil fully lubricates the secondary bearing 54. In this way, the rotation smoothness of the drive shaft 5 can be improved.

[0067] In some embodiments of the present invention, Figure 1 As shown, the cooling oil passage 111 is formed as a groove provided on the inner wall of the housing assembly 1. That is, a groove may be provided on the inner wall of the main housing 11, and the motor component 6 is supported on the portion of the inner wall of the main housing 11 where the groove is provided, so that the motor component 6 and the main housing 11 may define the cooling oil passage 111 at the groove. Through the above arrangement, the processing difficulty of the cooling oil passage 111 may be reduced, and the practicality of the compressor 100 may be improved.

[0068] Of course, the present application is not limited thereto, and a groove may also be provided on the outer peripheral wall of the motor component 6 , or grooves may be provided on the outer peripheral wall of the motor component 6 and the inner wall of the main housing 11 , respectively.

[0069] In some embodiments of the present invention, Figure 1 As shown, the cooling oil channel 111 can be constructed in a spiral shape. Thus, the lubricating oil in the cooling oil channel 111 can fully and comprehensively cool the motor component 6, which is beneficial to improving the working stability of the motor component 6.

[0070] In some embodiments of the present invention, Figure 1 and Figure 3As shown, the compressor 100 of the embodiment of the utility model further includes a first oil return channel 7, the first oil return channel 7 includes a first oil return section 71 and a second oil return section 72, the first oil return section 71 is arranged on the bracket 3, and the second oil return section 72 is arranged on the shell assembly 1, the first oil return section 71 is used to communicate with the back pressure chamber 41, and the second oil return section 72 is respectively connected to the first oil return section 71 and the cooling oil channel 111, so that the back pressure chamber 41 can be connected with the cooling oil channel 111 through the first oil return section 71 and the second oil return section 72.

[0071] Specifically, after the lubricating oil flows into the back pressure chamber 41, the lubricating oil can flow into the second oil return section 72 along the first oil return section 71, and the lubricating oil flowing into the second oil return section 72 can flow into the cooling oil passage 111 along the second oil return section 72 to cool the motor component 6. Through the above arrangement, reliable communication between the back pressure chamber 41 and the cooling oil passage 111 can be achieved, which is beneficial to improving the reliability of the compressor 100.

[0072] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, a first seal 43 is sandwiched between the bracket 3 and the housing assembly 1. The first seal 43 is constructed in an annular shape and is used to seal the first oil return section 71 and the second oil return section 72 to prevent the lubricating oil in the first oil return channel 7 from leaking between the bracket 3 and the main housing 11. Specifically, the first seal 43 (as well as the second seal 44, the third seal 45 and the fourth seal 46 described below) can be made of elastic materials such as rubber. In this way, the sealing performance of the first oil return channel 7 can be improved, so that there can be sufficient flow in the cooling oil channel 111, ensuring the cooling effect.

[0073] In some embodiments of the present invention, the second oil return section 72 includes a first part 721 and a second part 722, the first part 721 is connected to the cooling oil channel 111 through the second part 722, the flow area of ​​the first part 721 is respectively greater than the flow area of ​​the second part 722 and the flow area of ​​the first oil return section 71, and the flow area of ​​the second part 722 is smaller than the flow area of ​​the cooling oil channel 111.

[0074] For example, Figure 3 As shown, the second oil return section 72 includes a first part 721 and a second part 722. The first part 721 is extended along the radial direction of the main housing 11, and the second part 722 is extended along the axial direction of the main housing 11. One end of the second part 722 is in communication with the cooling oil channel 111, and the other end of the second part 722 is in communication with the first part 721, so that the first part 721 can be connected to the cooling oil channel 111 through the second part 722.

[0075] Among them, the flow area of ​​the first part 721 can be set to be larger than the flow area of ​​the second part 722 and the flow area of ​​the first oil return section 71, so that the first part 721 can be formed into a buffer space for buffering the impact of the lubricating oil when it flows from the first oil return section 71 into the second oil return section 72, thereby improving the flow stability of the lubricating oil and making it easier to dock the first oil return section 71 and the second oil return section 72, thereby reducing the difficulty of installing the compressor 100. At the same time, the flow area of ​​the second part 722 can also be set to be smaller than the flow area of ​​the cooling oil channel 111, so that when the lubricating oil flows from the second part 722 into the cooling oil channel 111, the flow rate of the lubricating oil will be slowed down, so that the lubricating oil can fully exchange heat with the motor component 6, thereby improving the cooling effect.

[0076] In some embodiments of the present invention, the housing assembly 1 is provided with a second oil storage chamber 42, the second oil storage chamber 42 is connected to the back pressure chamber 41 through the second oil return channel 8, and the second oil storage chamber 42 is connected to the compression chamber of the scroll assembly 2 through the third oil return channel 222.

[0077] That is to say, Figure 1 As shown, the housing assembly 1 is provided with a second oil storage chamber 42, which is communicated with the back pressure chamber 41 through the second oil return passage 8, and the second oil storage chamber 42 is communicated with the compression chamber of the scroll assembly 2 through the third oil return passage 222. In this way, when the scroll assembly 2 starts to operate, the lubricating oil in the back pressure chamber 41 can flow into the second oil storage chamber 42 through the second oil return passage 8, and the lubricating oil in the second oil storage chamber 42 can flow into the compression chamber through the third oil return passage 222, so that the lubricating oil can be compressed together with the refrigerant, and discharged into the first oil storage chamber 121 after compression. In this way, the circulation speed of the lubricating oil can be accelerated and the lubrication effect can be improved.

[0078] In some embodiments of the present invention, Figure 1 As shown, the third oil return passage 222 is provided at the second scroll 22 of the scroll assembly 2. Specifically, a second oil storage chamber 42 may be provided on the side of the end cover 12 facing the second scroll 22, and a third oil return passage 222 may be provided on the second scroll 22 corresponding to the second oil storage chamber 42, so that the second oil storage chamber 42 may flow into the compression chamber through the third oil return passage 222.
