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

[0036] A scroll compressor 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the scroll compressor 100 according to the embodiment of the present utility model includes a housing 1 , a lower supporting structure 5 and an oil retaining assembly 6 .

[0038] Specifically, Figure 1 As shown, the compressor further includes a compression mechanism 2, a motor 4 and a crankshaft 3, the compression mechanism 2, the motor 4 and the crankshaft 3 are arranged in the housing 1, and the compression mechanism 2 is located above the motor 4. The compression mechanism 2 includes a movable scroll 21 and a fixed scroll 22, the movable scroll 21 and the fixed scroll 22 cooperate with each other, and the movable scroll 21 is connected to the eccentric part of the upper end of the crankshaft 3. The motor 4 includes a stator 41 and a rotor 42, the outer peripheral wall of the stator 41 is connected to the inner peripheral wall of the housing 1, the rotor 42 is rotatably arranged in the stator 41, and the rotor 42 has a through hole for the crankshaft 3 to pass through. The rotor 42 is connected to the crankshaft 3 and rotates synchronously with the crankshaft 3, thereby driving the movable scroll 21 to rotate.

[0039] The bottom of the housing 1 has an oil pool 11, the lower end of the crankshaft 3 extends out of the through hole, the crankshaft 3 has an oil channel, and the lower end of the crankshaft 3 is provided with an oil pump 7, which is used to supply oil in the oil pool 11 to the motor 4 and the compression mechanism 2 through the oil channel. The lower support structure 5 is arranged in the housing 1 and connected to the housing 1, the lower support structure 5 is located below the motor 4 and above the oil pool 11, the crankshaft 3 is passed through the lower support structure 5, and the lower support structure 5 is used to install and support the lower end of the crankshaft 3.

[0040] The oil baffle assembly 6 is an integrated part and includes an oil baffle plate 61 and a filling block 62. The oil baffle plate 61 is arranged at the lower side of the lower support structure 5 and connected to the lower support structure 5, and the filling block 62 is arranged at the lower side of the oil baffle plate 61. By installing the oil baffle plate 61 below the lower support structure 5, the liquid level of the oil pool 11 can be better stabilized and the oil circulation rate can be reduced. By setting the filling block 62, the lower part of the filling block 62 can be immersed in the oil, which can reduce the volume of the oil and the refrigerant to meet the PED Class II level.

[0041] Among them, the oil baffle plate 61 and the filling block 62 are an integrated part, which can increase the rigidity of the overall structure of the lower support structure 5 and the oil baffle assembly 6, thereby reducing the structural resonance radiation noise. In addition, since the oil baffle plate 61 and the filling block 62 are an integrated part, the oil baffle plate 61 can be prevented from hitting the filling block 62, reducing the impact noise, and reducing the surface area of ​​the surface of the oil baffle plate 61 and the filling block 62 facing each other, further reducing the radiation noise. In addition, the filling block 62 and the oil baffle plate 61 are an integrated part, which can reduce the assembly process of the scroll compressor 100 and improve production efficiency.

[0042] In summary, combined with experimental verification, the heat pump 135cc-R290 model adopts an integrated oil baffle 61 and a filling block 62, which can effectively improve the wide-band noise in the low-frequency range of the scroll compressor 100, and the total noise value can be reduced by 3.5dB. In addition, the solution is easy to implement, efficient, and has a high overall cost-effectiveness.

[0043] According to the scroll compressor 100 of the embodiment of the utility model, an oil baffle assembly 6 is arranged on the lower side of the lower support structure 5, and the oil baffle assembly 6 includes an oil baffle plate 61 and a filling block 62 which are arranged integrally, the oil baffle plate 61 is located on the lower side of the lower support structure 5 and connected to the lower support structure 5, and the filling block 62 is located on the lower side of the oil baffle plate 61, while reducing the oil circulation rate, the volume of the oil and the refrigerant is reduced to meet the PED II grade, and the rigidity of the entire assembly of the lower support structure 5 and the oil baffle plate 61 can be increased, the surface area of ​​the entire assembly can be reduced, the radiation noise can be reduced, and the noise of the oil baffle plate 61 hitting the filling block 62 can be reduced. In addition, the filling block 62 and the oil baffle plate 61 are an integral part, which can also reduce processing and assembly, and improve production efficiency.

[0044] In some embodiments of the present invention, Figure 2 As shown, the filling block 62 is annular and is arranged around the crankshaft 3 and the oil pump 7. In this way, the volume of the filling block 62 can be increased as much as possible while ensuring that the filling block 62 does not interfere with the crankshaft 3 and the oil pump 7, thereby reducing the volume of the lubricating oil and the refrigerant to meet the PED Class II level. In addition, the annular filling block 62 can uniformly increase the stiffness of the oil baffle 61 in the circumferential direction of the oil baffle 61, thereby increasing the stiffness of the lower support structure 5, and then increasing the stiffness of the entire lower support structure 5 and the oil baffle 61 assembly as a whole, reducing the structural resonance radiation noise.

[0045] Optionally, the central axis of the annular filling block 62 is colinear with the central axis of the crankshaft 3 .

[0046] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the peripheral wall of the filling block 62 is provided with a connecting hole 621, and the connecting hole 621 penetrates the filling block 62. When the filling block 62 is annular and the lower end of the filling block 62 is immersed in oil, the pressure of the inner space and the outer space of the filling block 62 are different. By providing the connecting hole 621 on the peripheral wall of the filling block 62, the inner space and the outer space of the filling block 62 can be connected, and the pressure inside and outside the filling block 62 is balanced, which is conducive to the oil backflow to the lower part of the oil pump 7, ensuring that the oil pump 7 can continuously absorb oil, thereby ensuring the lubrication and cooling of the motor 4 and the compression mechanism 2 and other components.

[0047] Furthermore, if Figure 2 and Figure 4As shown, the connecting hole 621 is located at the upper end of the filling block 62. This can prevent the connecting hole 621 from being immersed in oil and blocked, and can ensure that the connecting hole 621 is in a conducting state and is prevented from being blocked by oil, so that the internal space and the external space of the filling block 62 are connected, and the pressure inside and outside the filling block 62 is balanced, which is conducive to the oil backflow to the lower part of the oil pump 7, ensuring that the oil pump 7 can continuously absorb oil, thereby ensuring the lubrication and cooling of the motor 4 and the compression mechanism 2 and other components.

[0048] Alternatively, if Figure 2 and Figure 4 As shown, there are multiple communicating holes 621, and the multiple communicating holes 621 are arranged at intervals along the circumferential direction of the filling block 62. This can increase the communicating area of ​​the inner and outer spaces of the filling block 62, which is conducive to achieving the balance of the inner and outer pressures of the filling block 62, and is conducive to the oil flowing back to the lower part of the oil pump 7, ensuring that the oil pump 7 can continuously absorb oil, thereby ensuring the lubrication and cooling of the motor 4 and the compression mechanism 2 and other components.

[0049] Alternatively, if Figure 2 and Figure 4 As shown, the plurality of connecting holes 621 are evenly spaced apart along the circumferential direction of the filling block 62, thereby simplifying the structure and processing technology of the filling block 62, improving production efficiency, and reducing production costs. In addition, the structural strength and rigidity of the filling block 62 along the circumferential direction of the filling block 62 can be made more uniform, which is conducive to reducing the resonance radiation noise.

[0050] Of course, the present invention is not limited thereto, and the plurality of communication holes 621 may also be unevenly distributed along the circumferential direction of the filling block 62 .

[0051] Furthermore, if Figure 4 As shown, the plurality of connecting holes 621 are located at the same height of the filling block 62, thereby simplifying the structure and processing technology of the filling block 62, improving production efficiency, and reducing production costs. In addition, the structural strength and rigidity of the filling block 62 along the circumferential direction of the filling block 62 can be made more uniform, which is conducive to reducing the resonance radiation noise.

[0052] Of course, the utility model is not limited to this. There are at least two connecting holes 621 among the multiple connecting holes 621 located at different heights of the filling block 62. This can ensure that when some connecting holes 621 are blocked by oil, some connecting holes 621 are still in a connected state, ensuring the pressure balance of the space inside and outside the filling block 62, which is conducive to the oil flowing back to the lower part of the oil pump 7.

[0053] Optionally, the oil baffle plate 61 is connected to the lower support structure 5 by fasteners, threaded connection, interference connection or clamping connection, thereby simplifying the connection mode between the oil baffle plate 61 and the lower support structure 5 and improving the connection reliability between the oil baffle plate 61 and the lower support structure 5, thereby reducing noise and improving the reliability of the scroll compressor 100.

[0054] In some embodiments of the present invention, Figure 1 As shown, the lower support structure 5 includes a support ring 51 and a sub-frame 52. The support ring 51 is connected to the shell 1, and the sub-frame 52 is connected below the support ring 51. The sub-frame 52 is used to support the lower end of the assembled crankshaft 3, and the support ring 51 plays a role in fixing the sub-frame 52 and the shell 1.

[0055] like Figure 1 and Figure 3 As shown, the oil baffle plate 61 is disposed below the auxiliary frame 52 and connected to the auxiliary frame 52. The oil baffle plate 61 and the auxiliary frame 52 may be connected by fasteners, the oil baffle plate 61 is provided with a first mounting hole 611 for the fastener to pass through, the auxiliary frame 52 is provided with a second mounting hole 5221 for the fastener to pass through, and the first mounting hole 611 and the second mounting hole 5221 are opposite and connected.

[0056] Furthermore, if Figure 3 As shown, the first mounting holes 611 are multiple and spaced apart along the circumferential direction of the oil baffle plate 61 , and the second mounting holes 5221 are multiple and spaced apart along the circumferential direction of the auxiliary frame 52 , and the multiple first mounting holes 611 and the multiple second mounting holes 5221 correspond one to one.

[0057] In some embodiments of the present invention, Figure 1 As shown, the support ring 51 includes a mounting portion 511 and a bracket 512. The mounting portion 511 is provided with a central mounting hole 5111. One end of the sub-frame 52 is assembled in the central mounting hole 5111. The bracket 512 is a plurality of brackets spaced apart along the circumferential direction of the mounting portion 511. The bracket 512 extends along the radial direction of the mounting portion 511. One end of the bracket 512 is connected to the outer peripheral wall of the mounting portion 511, and the other end is connected to the inner peripheral wall of the shell 1.

[0058] The central mounting hole 5111 is used for the crankshaft 3 to pass through, the inner wall of the central mounting hole 5111 is spaced apart from the outer peripheral wall of the crankshaft 3, a portion of the auxiliary frame 52 is located between the inner peripheral wall of the central mounting hole 5111 and the crankshaft 3, and the crankshaft 3 is assembled in the auxiliary frame 52 and can rotate in the auxiliary frame 52. The bracket 512 is connected to the mounting portion 511 and the housing 1, and plays a role in supporting and fixing the mounting portion 511.

[0059] It can be understood that the mounting portion 511 is an annular structure, and the mounting portion 511 is supported by a plurality of brackets 512 arranged at intervals on the outer circumference of the mounting portion 511, so that the force on the mounting portion 511 is more balanced and the supporting strength is better.

[0060] Optionally, the number of the brackets 512 may be 2, 3, or 4, etc., which is not limited here.

[0061] In some embodiments of the present invention, Figure 1 As shown, one end of the bracket 512 away from the mounting portion 511 has a boss 513 protruding toward the side of the sub-frame 52, and is fixedly connected to the housing 1 through the boss 513. Optionally, the boss 513 is welded to the housing 1. The boss 513 extends downward from the bracket 512, and the boss 513 is perpendicular to the bracket 512. By setting a right-angle structure, the structural strength of the support ring 51 is enhanced, and the boss 513 increases the connection area with the housing 1, so that the fixed connection between the support ring 51 and the housing 1 is more stable and reliable.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, the outer peripheral wall of the oil baffle plate 61 has a notch 612 for avoiding the boss 513. This can maximize the height of the boss 513 in the vertical direction, avoid interference between the oil baffle plate 61 and the boss 513, and ensure the reliability of the connection between the support ring 51 and the housing 1.

[0063] In some embodiments of the present invention, Figure 1 As shown, the auxiliary frame 52 includes a bearing support portion 521 and a connecting arm 522. The bearing support portion 521 is provided with a bearing hole 5211 for assembling the crankshaft 3, and the crankshaft 3 can rotate in the bearing hole 5211. The upper end of the bearing support portion 521 is assembled in the central mounting hole 5111, which plays a role of limiting positioning. The connecting arm 522 is a plurality of connecting arms 522 spaced apart along the circumferential direction of the bearing support portion 521, one end of the connecting arm 522 is connected to the bearing support portion 521, and the other end extends radially outward from the bearing support portion 521. The plurality of connecting arms 522 are respectively arranged below the plurality of brackets 512 and connected to the brackets 512, so as to realize the fixed connection between the auxiliary frame 52 and the support ring 51.

[0064] Optionally, the connecting arm 522 and the bracket 512 correspond one to one, which can increase the connection area between the two. The connecting arm 522 and the bracket 512 can be connected by a fastener. The connecting arm 522 is provided with a third mounting hole 5222 for the fastener to pass through, and the bracket 512 is provided with a fourth mounting hole 5121 for the fastener to pass through.

[0065] It can be understood that the bearing support part 521 is a cylindrical structure, and a plurality of connecting arms 522 are arranged at intervals around the outer periphery of the bearing support part 521. By providing a plurality of connecting arms 522 to support the bearing support part 521, the force on the bearing support part 521 is more balanced and the support strength is higher. Optionally, the connecting arms 522 can be 2, 3 or 4, etc., which are not limited here.

[0066] like Figure 1 As shown, the oil baffle plate 61 is sleeved outside the bearing support portion 521 and is located below the connecting arm 522, and the oil baffle plate 61 is connected to the bearing support portion 521 and / or the connecting arm 522.
