The channel 221 is connected to the oil pool 14; the pump body 3 is installed in the accommodating cavity 11 and is located below the motor part 2, the crankshaft 22 is passed through and connected to the pump body 3, and the pump body 3 is provided with an oil return channel 33 connected to the oil pool 14, and the oil return channel 33 is used to guide the oil flowing down from the motor part 2 to the oil pool 14, the pump body 3 includes a main bearing 31 and a cylinder 32, the main bearing 31 is located on the side of the cylinder 32 close to the motor part 2, the main bearing 31 is rotatably matched with the crankshaft 22, and the main bearing 31 is formed with an oil return inlet 331 of the oil return channel 33; the partition plate 4 is provided between the motor part 2 and the main bearing 31, and the partition plate 4 is opposite to at least part of the oil return inlet 331 along the axial direction of the crankshaft 22.
[0034] In this way, the impact of the trimming return air on the oil pool 14 can be reduced, the stability of the oil in the oil pool 14 is improved, the lubrication effect of the oil is ensured, and the operating stability of the compressor 100 is improved.
[0035] First, if Figures 1-4 As shown, the compressor 100 includes a housing 1, a motor 2, and a pump body 3. A housing 1 is provided within the housing 1. An exhaust passage 12 is provided at the top of the housing 11, and an intake passage 13 is provided on the sidewall. The intake passage 13 communicates with the outside of the housing 1. The exhaust passage 12 is used to connect the housing 11 with the outside of the housing 1. An oil pool 14 is provided at the bottom of the housing 11.
[0036] The motor part 2 is installed in the accommodating chamber 11 and is located at the upper part of the accommodating chamber 11. The motor part 2 includes a motor 21 and a crankshaft 22. The motor 21 includes a stator 211 and a rotor 212. The stator 211 is connected to the inner wall of the accommodating chamber 11 and is sleeved on the outside of the rotor 212. The crankshaft 22 axially penetrates the rotor 212 and extends to the bottom of the motor 21. The crankshaft 22 is connected to the rotor 212. The stator 211 can drive the rotor 212 to rotate to drive the crankshaft 22 to rotate synchronously.
[0037] A first oil supply passage 221 and a second oil supply passage 222 are formed in the crankshaft 22, extending axially and arranged sequentially. The second oil supply passage 222 is located above and communicates with the first oil supply passage 221. The lower end of the crankshaft 22 extends downward into the oil reservoir 14, connecting the first oil supply passage 221 with the oil reservoir 14. The second oil supply passage 222, at one end facing away from the first oil supply passage 221, extends to the upper portion of the motor 21. An oil pump 5 is disposed within the first oil supply passage 221, and is used to draw oil into the first oil supply passage 221. The second oil supply passage 222 directs the oil in the first oil supply passage 221 to the upper portion of the motor 21.
[0038] The pump body 3 is installed in the accommodating chamber 11 and is located below the motor part 2. The pump body 3 is provided with an oil return channel 33, which is used to transfer the oil flowing down from the motor part 2 into the oil pool 14. The pump body 3 includes a main bearing 31 and a cylinder 32. The crankshaft 22 is connected to the cylinder 32. The cylinder 32 is connected to the intake channel 13. The crankshaft 22 is used to drive the cylinder 32 to operate so that the cylinder 32 can absorb the refrigerant from the intake channel 13 and compress it. The main bearing 31 is located on the side of the cylinder 32 close to the motor part 2. The main bearing 31 is fixedly connected to the inner wall of the accommodating chamber 11, such as by welding. The main bearing 31 is sleeved on the outside of the crankshaft 22 and rotatably cooperates with the crankshaft 22 to make the rotation of the crankshaft 22 more stable. The main bearing 31 is formed with an oil return inlet 331 of the oil return channel 33.
[0039] At the same time, the rotor 212 is provided with a refrigerant channel 2122 penetrating along the axial direction of the crankshaft 22 , and the refrigerant channel 2122 is used to connect the pump body 3 with the exhaust channel 12 .
[0040] Specifically, when the compressor 100 starts to operate, the motor 21 can drive the crankshaft 22 to rotate, and the crankshaft 22 can drive the cylinder 32 to operate. The cylinder 32 can suck in the refrigerant from the outside of the shell 1 through the intake channel 13 and compress it. The compressed refrigerant can flow through the refrigerant channel 2122 and the exhaust channel 12 to be discharged to the outside of the shell 1. At the same time, the oil pump 5 can suck the oil in the oil pool 14 into the first oil supply channel 221. The oil flows upward along the first oil supply channel 221 into the second oil supply channel 222. The oil can flow out from the upper end of the second oil supply channel 222 to the top of the motor 21 to cool the motor 21. The oil can then flow downward to flow into the oil return channel 33 from the oil return inlet 331. The oil flowing into the oil return channel 33 can lubricate the pump body 3 and flow back to the oil pool 14 along the oil return channel 33.
[0041] It should be noted that during the exhaust process, part of the refrigerant will collide with the shell part 1 to form trimmed return air, which will flow into the oil pool 14 to impact the oil in the oil pool 14, thereby affecting the lubrication effect of the oil on the compressor 100.
[0042] To address the above issues, the compressor 100 can be configured to further include a partition plate 4, which is installed in the accommodating chamber 11 and disposed between the motor unit 2 and the main bearing 31. The partition plate 4 is aligned with at least a portion of the oil return inlet 331 along the axial direction of the crankshaft 22, thereby providing some shielding against the oil return inlet 331. Thus, when the trimmed return air flows toward the oil return inlet 331, the partition plate 4 can block the trimmed return air, thereby reducing its impact on the oil pool 14 and ensuring the stability of the oil in the oil pool 14, allowing the first oil supply channel 221 to better extract the oil. This ensures the lubrication effect of the compressor 100.
[0043] In addition, by arranging the partition plate 4 between the motor part 2 and the main bearing 31, the space in the accommodating cavity 11 can be fully utilized, which is conducive to eliminating the possibility of interference between the partition plate 4 and the motor part 2 or the pump body part 3, reducing the processing accuracy requirements and installation difficulty of the partition plate 4, and improving the design rationality of the compressor 100.
[0044] According to the compressor 100 of the embodiment of the present invention, a partition plate 4 is provided between the motor part 2 and the pump body part 3, so that the partition plate 4 can block the return oil inlet 331 to a certain extent, thereby reducing the impact of the trimming return air on the oil pool 14, improving the stability of the oil in the oil pool 14, and ensuring the lubrication effect of the oil, thereby improving the operating stability of the compressor 100.
[0045] In some embodiments of the present invention, Figure 3As shown, in the axial direction of the crankshaft 22, the partition plate 4 is located above the oil return inlet 331 to block the oil return inlet 331. The partition plate 4 is provided with an oil hole 421 connected to the oil return inlet 331. The oil hole 421 is used to guide the oil falling on the partition plate 4 to the oil return inlet 331. The axial direction of the oil hole 421 can be arranged to intersect with the axial direction of the oil return inlet 331 or to be arranged parallel to the axial direction of the oil return inlet 331 to limit the trimming return air from flowing into the oil return inlet 331 through the oil hole 421. In this way, the shielding effect of the partition plate 4 on the oil return inlet 331 can be improved, which helps to reduce the impact on the oil pool 14, and can also improve the oil return efficiency, thereby improving the practicality of the compressor 100.
[0046] In some embodiments of the present invention, the main bearing 31 includes a first plane 311 and a connecting bevel 312. In the radial direction of the crankshaft 22, the outer side of the connecting bevel 312 is connected to the first plane 311 and the inner side extends obliquely in a direction away from the motor part 2. The return oil inlet 331 is provided on the connecting bevel 312, and the partition plate 4 is supported on the first plane 311 and is opposite to the return oil inlet 331 along the axial direction of the crankshaft 22.
[0047] For example, refer to Figure 2-Figure 4 As shown, the main bearing 31 includes a first plane 311 and a connecting bevel 312. The first plane 311 is located at the edge of the main bearing 31 and extends along the circumference of the crankshaft 22. In the radial direction of the crankshaft 22, the connecting bevel 312 is located on the inner side of the first plane 311. The outer side of the connecting bevel 312 is connected to the inner side of the first plane 311 and the inner side extends obliquely away from the motor unit 2. The oil return inlet 331 is provided on the connecting bevel 312. The partition plate 4 is constructed in an annular shape. The outer side of the partition plate 4 is supported by the first plane 311, and the inner side extends to the inner side of the oil return inlet 331. This allows the partition plate 4 to directly face the oil return inlet 331 along the axial direction of the crankshaft 22, thereby fully shielding the oil return inlet 331.
[0048] Through the above arrangement, the shielding effect of the partition plate 4 on the return oil inlet 331 can be improved, the impact of the trimmed return air on the oil pool 14 can be fully reduced, the stability of the oil is improved, and the operating stability of the compressor 100 is ensured.
[0049] In some embodiments of the present invention, the main bearing 31 also includes a second plane 313, which is connected to the radial inner side of the connecting bevel 312 along the crankshaft 22. The partition plate 4 includes a main plate 41 and an extension plate 42. The extension plate 42 is connected to the inner edge of the main plate 41 and extends away from the motor part 2. The main plate 41 is supported on the first plane 311 and is opposite to the return oil inlet 331 along the axial direction of the crankshaft 22. The extension plate 42 is supported on the second plane 313 and is provided with an oil hole 421.
[0050] For example, refer to Figure 2As shown, the main bearing 31 further includes a second flat surface 313, which is located on the side of the first flat surface 311 facing away from the motor unit 2 and is connected to the inner side of the connecting inclined surface 312 along the radial direction of the crankshaft 22. The partition plate 4 includes a main plate 41 and an extension plate 42. Both the main plate 41 and the extension plate 42 are annular in shape. The extension plate 42 is connected to the inner edge of the main plate 41 and extends away from the motor unit 2. The main plate 41 is supported on the first flat surface 311 and faces the oil return inlet 331 along the axial direction of the crankshaft 22. The extension plate 42 is supported on the second flat surface 313 and is provided with an oil hole 421. The axial direction of the oil hole 421 extends along the radial direction of the crankshaft 22, so that the axial direction of the oil hole 421 is perpendicular to the axial direction of the oil return inlet 331.
[0051] The above arrangement can effectively prevent the trimming return air from flowing from the oil hole 421 to the oil return inlet 331 , thereby improving the shielding effect of the partition plate 4 on the oil return inlet 331 .
[0052] Furthermore, if Figure 3 As shown, the oil hole 421 can be arranged opposite to the oil return inlet 331 along the radial direction of the crankshaft 22. As a result, the distance between the oil hole 421 and the oil return inlet 331 can be shortened, which helps to shorten the flow path of the oil and increase the circulation speed of the oil, thereby improving the lubrication effect of the oil on the compressor 100.
[0053] In some embodiments of the present invention, Figure 2 As shown, the outer edge of the main plate 41 can be fixed to the inner wall of the housing 1, for example, by welding the outer edge of the main plate 41 to the inner wall of the housing 1. This arrangement can improve the stable installation of the partition plate 4 and help ensure that the partition plate 4 has a shielding effect on the oil return inlet 331.
[0054] Of course, the housing portion 1 may also be mounted on the main bearing 31 by screwing or gluing, thereby reducing the difficulty of mounting the partition plate 4 .
[0055] In some embodiments of the present invention, Figure 2 As shown, a supporting flange 43 can be provided on the outer edge of the main board 41, and the supporting flange 43 extends in the direction close to the motor part 2 to construct the cross-sectional shape of the partition plate 4 into a Z-like shape, and the supporting flange 43 is designed to follow the shape of the shell part 1 so that the supporting flange 43 can be supported and connected to the inner wall of the shell part 1.
[0056] Through the above arrangement, the structural strength of the partition plate 4 can be improved, and the connection area between the partition plate 4 and the shell portion 1 can be increased, which is beneficial to improving the installation stability of the partition plate 4.
[0057] In some embodiments of the present invention, Figure 3As shown, the main bearing 31 may be provided with multiple oil return inlets 331, which are spaced apart along the axial direction of the crankshaft 22. Furthermore, a plurality of oil holes 421 may be provided, which are spaced apart along the circumference of the crankshaft 22, with each oil return inlet 331 corresponding to at least one oil hole 421.
[0058] Through the above arrangement, the oil return efficiency of the oil return inlet 331 can be improved, and the oil can be prevented from accumulating above the pump body 3 and affecting the flow of the refrigerant, thereby improving the reliability of the compressor 100.
[0059] In some embodiments of the present invention, the motor 21 is provided with a liquid guiding channel 2111, which is used to guide the oil of the motor part 2 to the pump body part 3, and the sum of the opening areas of the multiple oil holes 421 is not less than the cross-sectional area of the liquid guiding channel 2111.
[0060] For example, refer to Figure 1 As shown, a liquid guide channel 2111 can be provided on the stator 211 of the motor 21. The liquid guide channel 2111 extends axially along the crankshaft 22. The liquid guide channel 2111 is used to guide the oil on the motor portion 2 to the pump body 3, so that the oil can flow from the oil hole 421 into the oil return channel 33. The opening area of the plurality of oil holes 421 can be set to be no less than the cross-sectional area of the liquid guide channel 2111. In this way, the oil flowing down from the motor portion 2 can be promptly flowed into the oil return channel 33, thereby preventing the oil from accumulating above the pump body 3 and affecting the flow of the refrigerant.
[0061] In some embodiments of the present invention, a plurality of liquid-conducting channels 2111 may be provided, the plurality of liquid-conducting channels 2111 being spaced apart along the circumference of the crankshaft 22. The plurality of liquid-conducting channels 2111 correspond one-to-one to the plurality of oil return inlets 331, and the sum of the opening areas of the plurality of oil holes 421 is not less than the sum of the cross-sectional areas of the plurality of liquid-conducting channels 2111. This arrangement allows for a more uniform flow of oil within the accommodating chamber 11, thereby improving the cooling and lubricating effects of the oil.
