[0042] This invention proposes a scroll compressor, which aims to enhance lubrication between the moving and stationary scrolls by adding an oil groove near the oil outlet of the moving scroll plate to periodically connect with the high-pressure oil groove on the stationary scroll plate, thereby reducing wear and improving compressor performance. It is understood that this scroll compressor is applicable to different types of refrigeration equipment, such as refrigerators, air conditioners, and refrigerated trucks, and is not limited to any specific type of equipment. The structure of the scroll compressor is described below.

[0043] In embodiments of the present invention, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, the scroll compressor includes a stationary scroll plate 100 and a moving scroll plate 200.

[0044] A first oil groove 101 is provided on the end face of the stationary scroll plate 100; a moving scroll plate 200 is rotatably connected to the stationary scroll plate 100 and cooperates with the stationary scroll plate 100 to define a compression chamber; the moving scroll plate 200 is provided with a first oil supply channel 201, and the first oil supply channel 201 is provided with a first oil outlet 201a on the end face of the moving scroll plate 200, and the first oil outlet 201a is periodically connected with the first oil groove 101; a second oil groove 202 is also provided on the end face of the moving scroll plate 200, the second oil groove 202 is located on the side of the moving scroll plate 200 near the first oil outlet 201a, and the second oil groove 202 is suitable for periodically communicating with the first oil groove 101.

[0045] Understandably, in a scroll compressor, the moving scroll 200 is connected to the crankshaft 400. The rotation of the crankshaft 400 drives the moving scroll 200 to move relative to the stationary scroll 100. During the rotation of the moving scroll 200, the moving scroll teeth 220 of the moving scroll 200 and the stationary scroll teeth 110 of the stationary scroll 100 mesh with each other to compress the gas in the compression chamber and then discharge it from the exhaust port. The mutual cooperation structure between the moving scroll teeth 220 and the stationary scroll teeth 110 can refer to the cooperation structure in a conventional scroll compressor, and will not be described in detail here. During the movement of the moving scroll plate 200 relative to the stationary scroll plate 100, the end face of the stationary scroll plate 100 and the end face of the moving scroll plate 200 cooperate with each other. The end face of the stationary scroll plate 100 is provided with a first oil groove 101, and the moving scroll plate 200 is provided with a first oil supply channel 201. The first oil outlet 201a of the first oil supply channel 201 is opened on the end face of the moving scroll plate 200. During the movement of the moving scroll plate 200, it can drive the first oil outlet 201a to periodically connect with the first oil groove 101 to supply oil into the first oil groove 101, thereby playing a role in lubricating the stationary scroll plate 100 and the moving scroll plate 200. However, in compressors of related technologies, there are areas between the scroll plates that cannot be lubricated by the first oil groove 101 (e.g., areas where the first oil groove 101 does not extend, or areas where the distance between the first oil groove 101 and the scroll groove 120 / edge of the stationary scroll plate 100 is large). This results in insufficient lubrication in certain areas, leading to wear problems. Based on this, this embodiment provides a second oil groove 202 on the end face of the moving scroll plate 200. The second oil groove 202 is located on the side of the moving scroll plate 200 near the first oil outlet 201a and can periodically connect with the first oil groove 101 during the operation of the moving scroll plate 200. This allows the oil in the first oil groove 101 to flow into the second oil groove 202 for storage. Then, as the moving scroll plate 200 moves and sweeps, it can supply oil lubrication to the areas that cannot be lubricated by the first oil groove 101, thereby compensating for the defects of insufficient lubrication in certain areas, improving the overall lubrication capability between the moving scroll plate 200 and the stationary scroll plate 100, and reducing wear between the two.

[0046] It should be noted that in this embodiment, the first oil outlet 201a is periodically connected to the first oil trough 101. The purpose of this is to supply oil to the first oil trough 101 through the first oil supply channel 201. A second oil trough 202 is formed on the end face of the moving scroll 200 near the first oil outlet 201a, and the second oil trough 202 is periodically connected to the first oil trough 101. The purpose of this is that when the two are connected, the oil in the first oil trough 101 can be drawn into the second oil trough 202. Then, when the two are not connected, the oil in the second oil trough 202 can lubricate the end face of the moving scroll 200 and the end face of the stationary scroll 100, thereby lubricating areas that the oil in the first oil trough 101 cannot reach. This promotes rapid and sufficient lubrication of the entire end face of the scroll, improves the lubrication effect, reduces wear, and improves the reliability of the compressor.

[0047] Understandably, the area where the first oil trough 101 is connected to the first oil outlet 201a is the area with the most abundant oil in the first oil trough 101. The oil entering the first oil trough 101 from the first oil outlet 201a flows along the path of the first oil trough 101 to other areas of the first oil trough 101. By setting the second oil trough 202 close to the first oil outlet 201a, when the second oil trough 202 is connected to the first oil trough 101, it is easier for lubricating oil to enter the second oil trough 202 for storage. When the second oil trough 202 is disconnected from the first oil trough 101, the second oil trough 202 can sweep with the movement of the moving scroll 200 to lubricate the end faces of the two scrolls, thereby improving lubrication efficiency.

[0048] The first oil supply channel 201 supplies oil to the first oil tank 101. It can be understood that the scroll compressor includes a housing 300 and a crankshaft 400 located inside the housing 300 and connected to the moving scroll 200. An oil sump 310 is provided at the bottom of the housing 300. An oil suction channel 410 communicating with the oil sump 310 is provided inside the crankshaft 400. The outlet end of the oil suction channel 410 is connected to the first oil supply channel 201. Oil is pumped from the bottom of the housing 300 to the first oil supply channel 201 of the moving scroll 200 through the oil suction channel 410, and then the oil is transported to the first oil tank 101 through the first oil supply channel 201.

[0049] Optionally, the cross-sectional shape of the first oil tank 101 can be determined according to the actual situation, such as arc, V, U, square, triangle or other irregular shapes.

[0050] Optionally, the cross-sectional shape of the second oil tank 202 can be determined according to the actual situation, such as arc, V, U, square, triangle or other irregular shapes.

[0051] In the scroll compressor of this invention, a stationary scroll 100 and a moving scroll 200 cooperate to define a compression chamber. A first oil groove 101 is provided on the end face of the stationary scroll 100, and a first oil supply channel 201 is provided on the moving scroll 200. The first oil outlet 201a of the first oil supply channel 201 is periodically connected to the first oil groove 101, thus supplying oil to the first oil groove 101. By providing a second oil groove 202 on the end face of the moving scroll 200 near the first oil outlet 201a, the second oil groove 202 can periodically communicate with the first oil groove 101, allowing oil in the first oil groove 101 to flow into the second oil groove 202. This enables lubrication of areas that the oil in the first oil groove 101 cannot reach, compensating for insufficient local lubrication, improving the overall lubrication capacity between the moving scroll 200 and the stationary scroll 100, reducing wear between them, and improving the reliability of the compressor.

[0052] In one embodiment of this application, please refer to Figure 2 , Figure 6 as well as Figure 7 The stationary vortex disk 100 has a vortex groove 120 on the side facing the moving vortex disk 200. The first oil groove 101 at least partially surrounds the outer periphery of the vortex groove 120. The first oil groove 101 has a first oil inlet 101a at a position near the air intake end 120a of the vortex groove 120, and the first oil inlet 101a is located in the vortex extension direction of the vortex groove 120. The first oil outlet 201a is periodically connected to the first oil inlet 101a. The second oil groove 202 is located between the first oil outlet 201a and the air intake end 120a of the vortex groove 120.

[0053] Understandably, the stationary volute teeth 110 of the stationary volute disk 100 form a volute groove 120, and the moving volute teeth 220 of the moving volute disk 200 engage within the volute groove 120, meshing with the stationary volute teeth 110 to form a compression chamber. The stationary volute disk 100 is provided with an intake port, and the intake end 120a of the volute groove 120 communicates with the intake port to draw refrigerant gas into the compression chamber for compression. The first oil groove 101 is arranged in the outer region of the volute groove 120 of the stationary volute disk 100, and is entirely within the operating range of the end plate of the moving volute disk 200. The first oil groove 101 can be arranged at least partially around the outer periphery of the volute groove 120 to prevent the first oil groove 101 from communicating with the back pressure chamber of the moving volute disk 200.

[0054] In practical applications, since the vortex groove 120 extends in a vortex shape, the intake end 120a of the vortex groove 120 is located in the area near the outer side of the stationary vortex disk 100, and the exhaust end of the vortex groove 120 is located in the area near the center of the stationary vortex disk 100. Therefore, there will be a large solid area on the end face of the vortex groove 120 on the side of the intake end 120a. In addition, the oil section of the first oil groove 101 near the intake end 120a will bend outward in this area to adapt to the vortex shape of the vortex groove 120. As a result, there may be insufficient lubrication and wear near the intake end 120a of the vortex tooth 120. Based on this, in this embodiment, a first oil inlet 101a is provided at the position of the first oil groove 101 near the suction end 120a of the vortex groove 120, and the first oil outlet 201a is periodically connected to the first oil inlet 101a, so that more lubricating oil is supplied to the first oil inlet 101a, increasing the lubrication effect at the position of the vortex plate near the suction end 120a. At the same time, a second oil groove 202 is provided between the first oil outlet 201a and the suction end 120a of the vortex groove 120. Thus, when the second oil groove 202 is connected to the first oil groove 101, lubricating oil can enter the second oil groove 201 for storage. When the second oil groove 202 is not connected to the first oil groove 101, the second oil groove 202 can sweep and supply oil to the area of ​​the stationary vortex plate 100 near the suction end 120a under the movement of the moving vortex plate 200. In this way, the lubrication degree at the position of the vortex plate near the suction end 120a can be further improved, thereby eliminating wear and extending service life.

[0055] To ensure better fuel supply performance, please refer to [link / reference]. Figure 2 , Figure 6 as well as Figure 7 For example, the cross-sectional area of ​​the first oil inlet 101a can be larger than the cross-sectional area of ​​other areas of the first oil tank 101, for example, it can be set as a semi-circular tank, a circular tank or a square tank, etc.

[0056] Optionally, the first oil groove 101 can be an annular groove or a "C" shaped groove.

[0057] Furthermore, the second oil trough 202 is periodically connected to the first oil inlet 101a. As can be seen from the aforementioned embodiments, the oil supply area and oil volume at the first oil inlet 101a are larger than those in other areas of the first oil trough 101. In this embodiment, by periodically connecting the second oil trough 202 to the first oil inlet 101a, lubricating oil can enter the second oil trough 202 more quickly when it is connected to the first oil inlet 101a. Consequently, when the two are not connected, the second oil trough 202 contains enough lubricating oil to supply lubrication to the area between the first oil inlet 101a and the suction end 120a, further improving the oil supply efficiency and promoting rapid and sufficient lubrication of the entire end face area of ​​the scroll plate.

[0058] In one embodiment of this application, please refer to Figures 3 to 5 The second oil tank 202 is not connected to the first oil supply channel 201.

[0059] Understandably, the second oil tank 202 is located on the end face of the moving scroll plate 200, and the first oil outlet 201a is the oil outlet of the first oil supply channel 201 on the end face of the moving scroll plate 200. By not connecting the second oil tank 202 with the first oil supply channel 201, the second oil tank 202 will not divert the oil in the first oil supply channel 201, thereby allowing the oil in the first oil supply channel 201 to be fully introduced into the first oil outlet 201a to supply oil to the first oil inlet 101a, ensuring oil supply efficiency.

[0060] In addition, the fact that the second oil tank 202 is not connected to the first oil supply channel 201 can reduce the processing difficulty and improve the processing efficiency.

[0061] Optionally, the second oil groove 202 is a blind groove structure formed on the end face of the moving scroll disk 200.

[0062] In one embodiment of this application, please refer to Figure 2 , Figure 6 as well as Figure 7 The width of the second oil tank 202 is the same as that of the first oil tank 101.

[0063] In this embodiment, by making the width of the second oil groove 202 the same as the width of the first oil groove 101, sealing performance and excellent lubrication efficiency are ensured, while reducing processing costs.

[0064] In one embodiment of this application, please refer to Figure 2 , Figure 6 as well as Figure 7 A third oil groove 102 is also provided on the end face of the static vortex disk 100. The third oil groove 102 is spaced apart on the side of the first oil groove 101 away from the vortex groove 120. The first oil outlet 201a is periodically connected to the third oil groove 102, and the second oil groove 202 is not connected to the first oil groove 101 and the third oil groove 102.

[0065] According to the refrigerant pressure distribution, the first oil tank 101, which is closer to the vortex groove 120, is a high-pressure oil tank, and the third oil tank 102, which is farther away from the vortex groove 120, is a medium-pressure oil tank. In this embodiment, when the moving vortex disk 200 moves, it can drive the first oil outlet 201a to periodically connect with the first oil tank 101 and the third oil tank 102 respectively, so as to supply oil to the first oil tank 101 and the third oil tank 102.

[0066] When the moving scroll plate 200 moves, it will drive the second oil tank 202 to move together. By setting the second oil tank 202 to not connect the first oil tank 101 and the third oil tank 102, it is possible to prevent air leakage between the high-pressure first oil tank 101 and the medium-pressure third oil tank 102, and avoid the gas and liquid in the high-pressure area from flowing to the medium-pressure area, which would affect the reliability of the cooperation between the moving scroll plate 200 and the stationary scroll plate 100.

[0067] Optionally, the projection shape of the second oil groove 202 on the end face of the moving scroll 200 is arc-shaped. The arc-shaped opening of the second oil groove 202 can be set towards the first oil outlet 201a, and the extension direction of the second oil groove 202 forms an angle with the circumference of the moving scroll 200. Thus, during the movement of the moving scroll 200, the second oil groove 202 can be driven to sweep along a wider sweeping line. This setting can increase the sweeping area and sweeping efficiency, further improving lubrication efficiency. Furthermore, the end of the second oil groove 202 away from the center of the moving scroll 200 can be no more than the circumference of the first oil outlet 201a. This setting can ensure that the second oil groove 202 will not connect with the intermediate-pressure third oil groove 102 throughout the entire movement cycle, improving the structural reliability of the scroll.

[0068] In one embodiment, the first oil groove 101 is arranged in a ring around the outer periphery of the vortex groove 120, and the third oil groove 102 is arranged in a ring at intervals around the outer periphery of the first oil groove 101.

[0069] By surrounding the outer periphery of the stationary vortex gear 110 with the first oil groove 101, the length of the first oil groove 101 is extended, the lubrication area is increased, and the lubrication effect is improved. Correspondingly, the third oil groove 102 is arranged in a ring around the outer periphery of the first oil groove 101, so that the periphery of the stationary vortex disk 100 can be lubricated. Furthermore, by setting the third oil groove 102 and the first oil groove 101 alternately, air and oil leakage between the high-pressure oil groove and the medium-pressure oil groove is avoided.

[0070] As an example, the third oil groove 102 includes two annular oil grooves 1021 spaced apart and a plurality of connecting grooves 1022 connecting the two annular oil grooves 1021. The plurality of connecting grooves 1022 are distributed at intervals along the circumference of the stationary scroll plate 100. This arrangement can ensure both the lubrication between the end faces of the stationary scroll plate 100 and the moving scroll plate 200 and the surface pressure between the stationary scroll plate 100 and the moving scroll plate 200, thereby further improving the reliability of the fit between the moving scroll plate 200 and the stationary scroll plate 100.

[0071] In one embodiment of this application, please refer to Figure 1 as well as Figures 3 to 5The moving scroll 200 includes a moving disk body 210, moving scroll teeth 220 disposed on the moving disk body 210, and an eccentric bearing portion 230 for cooperating with the crankshaft 400; a first oil supply channel 201 is disposed on the moving disk body 210, and the first oil supply channel 201 is provided with a first oil inlet 201b, which is located on the side of the eccentric bearing portion 230 or the moving disk body 210 facing the eccentric bearing portion 230. The first oil inlet 201b is connected to the outlet end of the oil suction channel 410, and the first oil outlet 201a and the second oil groove 202 are both disposed on the end face of the moving disk body 210 facing the stationary scroll 100.

[0072] This embodiment illustrates the structure of the moving scroll plate 200. The moving scroll teeth 220 and the eccentric bearing portion 230 are respectively disposed at opposite ends of the moving plate body 210. The moving scroll teeth 220 mesh with the stationary scroll teeth 110 of the stationary scroll plate 100. The eccentric bearing portion 230 is connected to the crankshaft 400, and the crankshaft 400 drives the moving scroll plate 200 to rotate via the eccentric bearing portion 230. It is understood that an oil storage chamber is formed between the upper end of the crankshaft 400 and the eccentric bearing portion 230.
