Description

Technical Field

[0001] This invention relates to the field of compressor oil sump stabilization structure technology, and in particular to a compressor oil sump stabilization structure and a scroll compressor. Background Technology

[0002] The oil circulation inside a scroll compressor can generally be divided into two parts. One part involves lubricating the moving and stationary discs in the compressor pump body, then compressing and discharging the oil from the pump body. Some lubricating oil is discharged from the compressor with the high-pressure gas, while some returns to the oil sump under the influence of the airflow. The other part lubricates the main bearing components and then returns to the oil sump through the oil return component. Specifically, when the compressor supplies oil, the rotor in the oil pump provides the power for the circulation of lubricating oil through continuous rotation. However, during its rotation to draw in oil, it causes the lubricating oil in the oil sump to rotate circumferentially. When this force is strong, the liquid level in the center of the oil sump is lower than that around the perimeter. At this time, the oil pump will intermittently draw in air bubbles, which can easily lead to poor lubrication. Furthermore, when the compressor returns oil, the lubricating oil returns to the oil sump through components such as the motor and lower support under the action of gas force and gravity. However, this vertical impact force will cause significant disturbance to the oil sump, causing lubricating oil to splash. Ultimately, this results in a large amount of oil being discharged from the oil distribution pipe and the exhaust pipe, increasing the compressor's oil discharge rate.

[0003] In summary, when the compressor is running, the lubricating oil level in the oil sump fluctuates greatly under the action of circumferential rotational force and vertical impact force, which will generate a large number of bubbles and splashed lubricating oil, easily leading to insufficient oil supply and excessive oil discharge rate of the compressor.

[0034] In the description of this invention, it should be noted that the terms "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] This invention provides a compressor oil sump stabilization structure, specifically applicable to scroll compressors, which solves the problem of excessive fluctuations in oil sump level during operation of existing scroll compressors, leading to air bubbles being drawn into the oil pump and insufficient oil supply to the pump body.

[0037] like Figure 1 , Figure 2 as well as Figure 4 As shown, the present invention provides a compressor oil sump stabilization structure, which can be installed inside the compressor housing 1 to buffer the lubricating oil entering the oil sump 16. Specifically, the oil sump stabilization structure includes a support frame 8 and a filter device. The support frame 8 is installed inside the compressor cavity, and the filter device is installed on the upper end of the support frame 8. Specifically, the filter device is installed on the support frame 8 and can cover the through area where the lubricating oil enters the oil sump 16. This ensures that the lubricating oil passes smoothly through the filter device and returns to the oil sump. Most importantly, when the compressor returns oil, the filter device can provide a vertical buffering effect on the high-speed impact of the oil-gas mixture, ensuring the stability of the oil level in the oil sump, preventing lubricating oil splashing caused by the impact, reducing the compressor's oil discharge rate, ensuring sufficient oil intake by the oil pump, and providing continuous and stable oil supply to the pump body.

[0038] Preferably, in combination with the above schemes, such as Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the filter device is a ring mesh 10. Specifically, the ring mesh 10 is installed on the lower side of the support frame 8 and covers the through area between the support frame 8 and the support ring 9. Furthermore, the mesh density and number of layers of the ring mesh 10 should meet the requirement that the resistance of the lubricating oil is moderate when it passes through, so that it has a certain degree of passability and buffering effect. When the compressor is running, the oil-gas mixture that returns vertically to the oil sump can play a buffering role when passing through the ring mesh 10, so that the movement speed of the lubricating oil is reduced. At the same time, the mesh structure can also effectively capture and prevent the lubricating oil from splashing. Furthermore, a support ring 9 is provided on the inner wall of the cavity of the housing 1, so that the support frame 8 can be fixedly set on the support ring 9 to form an installation structure; the support frame 8 and the support ring 9 can also play the role of lubricating splash buffer; specifically, the ring mesh 10 is sleeved on the support frame 8 along the radial direction of the cavity, so as to cover the through area of ​​the lubricating oil entering the oil sump 16 along the radial direction of the cavity. This design ensures that the lubricating oil after lubrication can only enter the oil sump 16 after being buffered by the ring mesh 10, preventing lubricating oil splash caused by impact and reducing the oil discharge rate of the compressor.

[0039] Preferably, in combination with the above schemes, such as Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, in this embodiment, the oil sump stabilization structure also includes an oil stabilizing box 11. The oil stabilizing box 11 is disposed on the support frame 8 and located at the bottom of the ring network 10. The oil stabilizing box 11 can extend into the oil sump 16 to regulate the temperature of the lubricant in the oil sump 16 and prevent large fluctuations in the liquid level. Furthermore, after passing through the ring network 10, the lubricating oil can enter the oil stabilizing box 11 and impact the inner side of the oil stabilizing box 11, thereby playing a buffering role and preventing large fluctuations in the lubricating oil level in the oil stabilizing box 11. By adopting the above scheme, it can be ensured that the lubricating oil passes smoothly and returns to the oil sump 16. The ring network 10 can play a first vertical buffering role for the high-speed impact of the oil-gas mixture. The inclined polygonal oil stabilizing box 11 in the oil sump 16 can play a second vertical buffering role. At the same time, the oil stabilizing plate can reduce the internal circumferential disturbance and ensure the stability of the oil level in the oil sump.

[0040] Preferably, in combination with the above schemes, such as Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in this embodiment, the oil sump stabilization structure also includes an oil stabilizing box 11. Specifically, the oil stabilizing box 11 is mounted on the support frame 8 and located at the bottom of the ring network 10. After passing through the ring network 10, the lubricating oil can enter the oil sump 16 and impact the outer surface of the oil stabilizing box 11, thereby playing a buffering role and preventing large disturbances in the lubricating oil level in the oil sump 16. By adopting the above scheme, it can be ensured that the lubricating oil passes smoothly and returns to the oil sump 16. The ring network 10 can play a first vertical buffering role on the high-speed impact of the oil-gas mixture, and the inclined polygonal oil stabilizing box 11 in the oil sump 16 can play a second vertical buffering role. At the same time, the oil stabilizing plate can reduce the internal circumferential disturbance and ensure the stability of the oil level in the oil sump.

[0041] Preferably, in combination with the above schemes, such as Figures 6 to 9 As shown, in this embodiment, the side of the oil stabilizing box 11 is composed of multiple oil stabilizing plates 17, and two adjacent oil stabilizing plates 17 are not on the same plane; furthermore, the oil stabilizing plates 17 are arranged in an inclined manner, so that the lubricating oil can change its flow direction when it impacts the side of the oil stabilizing box 11; specifically, with the above scheme, when the lubricating oil comes into contact with the oil stabilizing box 11 through the ring network 10, the oil stabilizing plates 17 in the oil stabilizing box 11 play a second vertical buffering role on the flow path of the lubricating oil. At this time, the inclined oil stabilizing plates 17 can change the flow direction of the lubricating oil, making it flow along the oil stabilizing plates 17, reducing the vertical impact force.

[0042] Preferably, in combination with the above schemes, such as Figures 6 to 9As shown, the oil stabilizing plate 17 has concave and convex structures on each side, including the outer side and the inner side. With the above design, the special structure of the oil stabilizing plate 17 can effectively prevent the circumferential rotation of the lubricating oil. When there is a circumferential rotational force inside or outside the oil stabilizing plate 17, its irregular concave and convex structure can weaken this rotational effect, increase the resistance to circumferential rotation, and stabilize the lubricating oil inside. Similarly, the outer side of the oil stabilizing plate 17 can also effectively weaken the circumferential rotational force. Therefore, when the oil sump stabilizing structure is in the oil sump 16, it can reduce the circumferential rotation of the lubricating oil and stabilize the oil level in the oil sump.

[0043] Preferably, in combination with the above schemes, such as Figures 6 to 9 As shown, in this embodiment, the oil stabilizing box 11 has a hollow structure, and the opening of the oil stabilizing box 11 facing the ring network 10 is larger than the opening of the oil stabilizing box 11 facing the bottom of the oil pool 16. This can prevent the lubricant from sliding down and play a buffering role. Furthermore, the side of the oil stabilizing box 11 is concave towards the inner side of the oil stabilizing box 11, so that the side of the entire oil stabilizing box 11 forms an uneven structure. The side of the oil stabilizing box 11 includes an outer side and an inner side.

[0044] Preferably, in combination with the above schemes, such as Figures 10 to 11 As shown, in this embodiment, the oil stabilizing plate 17 is a filter plate 18. The filter plate 18 has multiple filter holes on its surface, which can prevent lubricating oil from splashing while achieving lubrication flow. Specifically, the density and number of layers of the filter plate 18 can be freely combined to achieve different effects of stabilizing the oil pool. In addition, a filter screen can be set at the bottom of the oil stabilizing box 11 to increase the filtration function.

[0045] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, in this embodiment, the oil sump stabilization structure also includes an oil pump filter 12 and an oil pump 13. Specifically, the oil pump filter 12 is mounted on the support frame 8 and located within the oil stabilization box 11. The oil pump filter 12 can filter the lubricant drawn into the oil pump 13. Further, the oil pump 13 is mounted on the support frame 8 and located within the oil pump filter 12. In the above scheme, when the compressor supplies oil, the oil stabilization box 11 can effectively stabilize the lubricant in the oil sump 16, preventing the lubricant in the oil sump 16 from being affected by the rotation of the rotor of the oil pump 13, which would cause air bubbles and result in poor lubrication.

[0046] Accordingly, in conjunction with the above schemes, such as Figures 1 to 2As shown, the present invention also provides a scroll compressor, including a housing 1 and an oil sump stabilizing structure; wherein, the oil sump stabilizing structure is disposed inside the housing 1; specifically, the oil sump stabilizing structure is the compressor oil sump stabilizing structure described above; further, the oil sump stabilizing structure is located at the upper end of the oil sump 16, thereby buffering the lubricating oil entering the oil sump 16, thereby preventing the lubricating oil from directly impacting the oil sump 16, and ensuring stable oil return and supply in the compressor oil sump.

[0047] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, in this embodiment, the present invention also provides a scroll compressor that further includes a crankshaft 6 and a motor 7; wherein, the motor 7 is disposed inside the housing 1, and the crankshaft 6 is disposed in the middle position inside the housing 1 along the axial direction of the housing 1; specifically, an oil sump stabilizing structure is disposed at the bottom of the motor 7, so that after the lubricating oil is cooled by the motor 7, it can be buffered by the oil sump stabilizing structure, avoiding the lubricating oil from directly impacting the oil sump 16 and splashing, causing a large amount of lubricating oil to be discharged from the oil distribution pipe 14 and the exhaust pipe 15, affecting the normal working performance of the compressor; furthermore, one end of the bottom of the crankshaft 6 passes through the motor 7 and is rotatably connected to the support frame 8; this design can realize the rotatable connection of the crankshaft 6, and can simultaneously install the ring network 10 and the oil stabilizing box 11.

[0048] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, in this embodiment, the scroll compressor also includes a scroll plate and a lower support 4; the lower support 4 is fixedly disposed inside the housing 1 and located on top of the motor 7; further, the scroll plate is disposed inside the housing 1 and located on top of the lower support 4; a bearing 5 is provided in the middle position of the lower support 4, and the bearing 5 is used to connect and install the crankshaft 6; further, one top end of the crankshaft 6 passes through the bearing 5 and is connected to the scroll plate for transmission; specifically, the crankshaft 6 and the bearing 5 are rotatably connected; specifically, when the scroll compressor is working, the lubricating oil passes through the motor 7 after lubricating the scroll plate and the bearing 5, and then enters the oil sump 16 through the oil sump stabilizing structure, which can effectively prevent the lubricating oil from impacting the oil sump, making the lubricating oil in the oil sump 16 more stable.

[0049] Preferably, in combination with the above schemes, such as Figures 1 to 5 As shown, in this embodiment, the scroll plate includes a stationary scroll plate 2 and a moving scroll plate 3; the stationary scroll plate 2 is disposed inside the housing 1 and located at the top of the motor 7; the moving scroll plate 3 is movably connected to the bottom of the stationary scroll plate 2; an oil equalization pipe 14 and an exhaust pipe 15 are also provided on the outer side wall of the housing 1, one end of the oil equalization pipe 14 is connected to the oil pool 16, and one end of the exhaust pipe 15 is connected to the cavity located at the top of the motor 7 inside the housing 1.
