Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a scroll compressor and an air conditioner having the same. Background Technology

[0002] Scroll compressors, as key fluid machinery in modern refrigeration and air conditioning systems, work by compressing gas using a variable-volume compression chamber formed by the meshing of a moving scroll and a stationary scroll. The moving scroll is driven by a crankshaft, and its scroll teeth closely engage with those of the stationary scroll. As the moving scroll rotates and translates, the volume of the compression chamber gradually decreases, forcing the gas inside to be compressed to a high-pressure state. However, the high-speed rotation and translation of the moving scroll on the inner support surface of the frame cause significant friction between the back of the moving scroll and the inner support surface. Over prolonged operation, this friction leads to wear on the scroll and frame surfaces, thus affecting the compressor's efficiency and lifespan.

[0003] Traditional scroll compressors typically lubricate by storing lubricating oil in an oil sump within the frame. The rotation and movement of the moving scroll propels the oil to the areas requiring lubrication, forming an oil film to reduce friction and wear. However, this method has a significant problem: the rotating bearings of the moving scroll agitate the lubricating oil in the sump, generating considerable energy consumption. This not only wastes energy but can also cause the lubricating oil temperature to rise, affecting its viscosity and lubrication effectiveness, thereby reducing the overall efficiency of the compressor. Summary of the Invention

[0004] The main objective of this invention is to provide a scroll compressor and an air conditioner having the same, so as to solve the problem of high power consumption caused by direct agitation of liquid lubricating oil in existing scroll compressors.

[0005] To achieve the above objectives, according to one aspect of the present invention, a scroll compressor is provided, comprising a stationary scroll, a moving scroll, a crankshaft for driving the moving scroll, and a support, wherein the crankshaft has an oil supply passage extending axially therein, and the scroll compressor further comprises:

[0006] Spraying component, which is equipped with spray nozzles;

[0007] The bearing section is located at one end of the moving scroll plate near the crankshaft. The bearing section is provided with an oil outlet hole. At least part of the spray element is located inside the bearing section so that the oil outlet hole communicates with the spray hole.

[0008] The crankshaft has an oil storage space between its top end and the inner wall of the bearing section. The oil storage space is connected to the spray hole. With the continuous supply of lubricating oil to the oil storage space, the lubricating oil in the oil storage space enters the oil outlet from the spray hole and is sprayed out from the oil outlet.

[0009] Furthermore, the nozzle includes: a first branch nozzle portion, one end of which is used to communicate with the oil storage space, and the other end of which is away from the oil storage space is used to communicate with the oil outlet.

[0010] Along the direction of lubricant spraying, the diameter of the first orifice gradually decreases.

[0011] Furthermore, the nozzle includes: a second branch nozzle portion, one end of which is connected to the end of the first branch nozzle portion away from the oil storage space;

[0012] The diameter of the first orifice remains constant along the direction of lubricant spray.

[0013] Furthermore, the nozzle also includes: a third branch nozzle, one end of which is connected to the end of the second branch nozzle that is away from the first branch nozzle, and the other end of the third branch nozzle is connected to the oil outlet.

[0014] Along the direction of lubricant spraying, the diameter of the third orifice gradually increases.

[0015] Furthermore, along the direction of lubricant spraying, the length of the first orifice is L1, and the length of the second orifice is L2;

[0016] Among them, L1 and L2 satisfy the following relationship: L1>L2.

[0017] Furthermore, along the direction of lubricant spraying, the length of the first orifice is L1, the length of the second orifice is L2, and the length of the third orifice is L3;

[0018] Among them, L1, L2 and L3 satisfy the following relationship: L1>L2>L3.

[0019] Furthermore, the diameter of the oil outlet is R1, and the diameter of the first branch hole is R2;

[0020] R1 and R2 satisfy the following relationship: R1>R2.

[0021] Furthermore, there are multiple oil outlet holes, which are arranged circumferentially around the axis of the bearing portion;

[0022] The spraying component is a ring-shaped part with multiple spray holes. These spray holes are arranged one-to-one with multiple oil outlet holes and are interconnected.

[0023] Furthermore, along the flow direction of lubricating oil in the oil supply channel, the oil outlet is located at the end relatively far from the bearing portion, and the spray hole is located in the middle of the spray component, so that when the spray hole and the oil outlet are connected, the axis of the spray hole coincides with the axis of the oil outlet.

[0024] According to another aspect of the present invention, an air conditioner is provided, including a compressor, which is the compressor described above.

[0025] By applying the technical solution of this invention, the connection between the oil storage space and the nozzle ensures that the lubricating oil can be effectively accumulated and kept under high pressure. When the pressure in the oil storage space increases to a certain level, the lubricating oil is sprayed at high speed through the nozzle, forming fine droplets that evenly cover the back of the moving scroll plate and the inner support surface of the bracket, forming a stable oil film. The formation of this oil film effectively reduces the direct contact and wear between the moving scroll plate and the bracket, improving the operational stability and service life of the scroll compressor.

[0026] By replacing traditional liquid oil supply with atomized oil supply, the power consumption of oil churning in the oil sump of the moving scroll bearing is reduced. Since the resistance of the atomized droplets is much smaller than that of liquid oil, the movement of the moving scroll is smoother, reducing frictional power consumption during operation and thus improving the overall energy efficiency of the scroll compressor.

[0027] With the connection between the oil outlet and the spray nozzle, excess atomized lubricating oil droplets can flow along the support wall and eventually be discharged from the oil return hole, avoiding excessive accumulation of lubricating oil in the support oil sump and reducing oil evaporation and contamination.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] As mentioned in the background section, this application provides a scroll compressor and an air conditioner having the same, to solve the problem of high power consumption caused by direct agitation of liquid lubricating oil in existing scroll compressors.

[0044] Example 1

[0045] like Figures 1 to 6 As shown, this application provides a scroll compressor, including a stationary scroll 1, a moving scroll 2, a crankshaft 4 for driving the moving scroll 2, and a support 3. The crankshaft 4 has an oil supply channel 41 extending axially therein. The scroll compressor also includes:

[0046] Spraying component 5, which has a spray hole 51;

[0047] The bearing part 22 is provided at one end of the moving scroll plate 2 near the crankshaft 4. The bearing part 22 is provided with an oil outlet hole 23. At least part of the spray element 5 is provided in the bearing part 22 so that the oil outlet hole 23 communicates with the spray hole 51.

[0048] An oil storage space 6 is formed between the top of the crankshaft 4 and the inner wall of the bearing part 22. The oil storage space 6 is connected to the spray hole 51 so that the lubricating oil in the oil storage space 6 enters from the spray hole 51 to the oil outlet hole 23 under the action of continuously supplying lubricating oil into the oil storage space 6, and is sprayed out from the oil outlet hole 23.

[0049] The scroll compressor provided in this application embodiment achieves effective atomization of lubricating oil by providing a spray element 5 in the bearing portion 22 of the moving scroll 2 and configuring spray holes 51 on the spray element 5. Specifically, when lubricating oil is input into the oil storage space 6 through the oil supply channel 41 in the crankshaft 4, since the oil storage space 6 is directly connected to the spray hole 51, the pressure of the lubricating oil in the oil storage space 6 will push the lubricating oil into the spray hole 51, and then into the oil outlet hole 23 of the bearing portion 22 through the spray hole 51, and finally sprayed onto the back side 21 of the moving scroll 2 and the inner support surface of the bracket 3.

[0050] During the rotational translation of the moving scroll plate 2, its bearing section 22 no longer directly contacts the liquid lubricating oil, but instead collides with the mist-like lubricating oil particles. Since the resistance of the mist droplets is much smaller than that of the liquid oil, the oil churning power consumption generated by the bearing section of the moving scroll plate 2 is greatly reduced, thus improving the energy efficiency of the compressor.

[0051] The lubricating oil is atomized and evenly covers the back 21 of the moving scroll plate and the inner support surface 31 of the bracket 3, forming a stable oil film layer. This effectively reduces direct contact and friction, improves lubrication uniformity and effect, delays component wear, and increases the service life of the scroll compressor.

[0052] With precise control of the spray component 5, excessive lubricating oil is prevented from lingering in the oil tank 32. Excess lubricating oil droplets can flow smoothly along the wall of the bracket 3 to the oil return hole 33 at the bottom for recycling, reducing waste and maintaining a clean environment in the oil tank 32, further reducing the additional power consumption caused by oil agitation.

[0053] Furthermore, the nozzle 51 includes: a first branch nozzle portion 511, one end of which is used to communicate with the oil storage space 6, and the other end of the first branch nozzle portion 511 away from the oil storage space 6 is used to communicate with the oil outlet 23.

[0054] Along the direction of lubricant spraying, the diameter of the first orifice 511 gradually decreases.

[0055] The diameter of the first orifice 511 gradually decreases along the direction of lubricant spraying. This design increases the flow resistance of the lubricant within the orifice 51, causing the lubricant flowing through this section to accelerate. The increased flow velocity leads to a decrease in pressure. When the lubricant rushes out of the narrowest part of the orifice 51 at high speed, the shear force of the fluid due to the sudden exposure to the open space causes the lubricant to spread rapidly, forming tiny droplets, significantly enhancing the atomization effect of the oil supply. The atomized lubricant particles are more widely dispersed, covering a larger area on the back side 21 of the moving vortex disk and the inner support surface 31 of the bracket 3, resulting in more uniform lubrication and improved overall lubrication efficiency.

[0056] The direct connection between the oil storage space 6 and the first branch hole 511 ensures the smooth flow of lubricating oil under high pressure. The gradually narrowing first branch hole 511 effectively prevents the moving scroll plate 2 from directly agitating a large amount of liquid oil during rotation and translation, reducing the direct contact area between the bearing part 22 and the lubricating oil, thereby significantly reducing the additional power consumption caused by the agitation of lubricating oil.

[0057] Through precise control of the first orifice section 511, the atomized lubricating oil particles can be accurately sprayed to the oil outlet 23 and evenly distributed on the back side 21 of the moving scroll plate and the inner support surface 31 of the bracket 3, reducing disordered flow and waste of lubricating oil. Excess lubricating oil droplets, during the translational motion of the moving scroll plate 2, can flow along the wall of the bracket 3 to the oil return hole 33 and be promptly recovered, preventing excessive accumulation in the oil sump 32, further reducing power consumption and improving the recycling rate of lubricating oil.

[0058] The atomized oil supply method of the first orifice section 511 and the spray orifice 51 reduces the direct friction between the moving scroll plate 2 and the inner support surface 31 of the bracket 3, and the resulting atomized oil film provides more effective protection for the contact surface. This not only reduces wear, but also reduces the contamination of the lubricating oil by metal particles generated by wear, extends the service life of the scroll compressor, and improves its operational stability and reliability.

[0059] Furthermore, the nozzle 51 includes a second branch nozzle 521, one end of which is connected to the end of the first branch nozzle 511 that is away from the oil storage space 6.

[0060] The diameter of the first orifice 511 is constant along the direction of lubricant spraying.

[0061] In the first orifice section 511, the lubricating oil undergoes a transition from a gradually decreasing diameter to a constant diameter. This process initially accelerates the lubricating oil through hydrodynamic effects, forming a high-speed fluid. When the fluid enters the second orifice section 521 with a constant diameter, the flow velocity stabilizes, providing more ideal flow conditions for subsequent atomization. This stable flow velocity ensures more uniform size and distribution of lubricating oil particles during atomization, improving lubrication effectiveness and coverage.

[0062] By dividing the nozzle 51 into a tapered first orifice portion 511 and a constant-diameter second orifice portion 521, the embodiments of this application can precisely control the flow of lubricating oil from the oil reservoir 6 to the back surface 21 of the moving scroll disk. The tapered design of the first orifice portion 511 ensures sufficient atomization, while the constant diameter of the second orifice portion 521 helps control the flow rate, reducing the risk of increased power consumption due to excessive atomization or excessively high flow rate.

[0063] The constant-diameter second orifice 521 provides a stable atomization injection channel for lubricating oil, avoiding hydrodynamic instability caused by orifice diameter changes, ensuring that the lubricating oil covers the back of the moving scroll plate 21 and the inner support surface 31 of the bracket 3 in the best condition, enhancing lubrication efficiency, reducing wear, and thus improving the operating stability and service life of the scroll compressor.

[0064] The combined design of the first orifice 511 and the second orifice 521 optimizes the distribution and flow of lubricating oil in the bearing section 22 of the moving scroll disk 2, allowing excess lubricating oil droplets to flow more smoothly to the wall of the support 3 and finally be discharged through the oil return hole 33. This improves the recycling of lubricating oil, reduces the residence time of oil in the oil sump 32, further reduces power consumption, and improves energy utilization efficiency.

[0065] Furthermore, the nozzle 51 also includes a third branch nozzle 531, one end of which is connected to the end of the second branch nozzle 521 that is away from the first branch nozzle 511, and the other end of the third branch nozzle 531 is connected to the oil outlet 23.

[0066] Along the direction of lubricant spraying, the diameter of the third orifice 531 gradually increases.

[0067] The lubricating oil accelerates from the oil storage space 6 through the first orifice 511 and enters the second orifice 521 where the flow rate stabilizes at a high level. When it flows through the gradually expanding third orifice 531, the fluid pressure drops rapidly due to the sudden increase in the flow area, causing the high-speed lubricating oil to spread rapidly at the outlet and form a large number of fine droplets.

[0068] The use of a gradually expanding third orifice 531 reduces the resistance encountered by the lubricating oil during injection, thereby lowering the power consumption of the bearing portion of the moving scroll 2. Furthermore, the formation of droplets reduces the direct contact area between the lubricating oil and the back surface 21 of the moving scroll 2 and the inner support surface 31 of the bracket 3, further reducing frictional power consumption. By effectively controlling the atomization pattern and injection effect of the lubricating oil, the overall energy efficiency of the compressor is significantly improved.

[0069] The design of the gradually expanding third orifice 531 helps to form a more robust and uniform oil film on the back side 21 of the moving scroll disk and the inner support surface 31 of the bracket 3.

[0070] Excessive atomized lubricating oil droplets can more easily flow along the wall of the support 3 to the oil return hole 33 during the translation and rotation of the moving vortex disk 2, promoting the recycling of lubricating oil. This design avoids excessive accumulation of oil in the oil sump 32, reduces energy loss caused by oil agitation, and at the same time, due to the optimized design of the nozzle 51, the atomization of lubricating oil is more concentrated and effective, reducing unnecessary evaporation and loss.

[0071] Furthermore, along the direction of lubricant spraying, the length of the first orifice 511 is L1, and the length of the second orifice 521 is L2.

[0072] Among them, L1 and L2 satisfy the following relationship: L1>L2.

[0073] Furthermore, along the direction of lubricant spraying, the length of the first branch hole 511 is L1, the length of the second branch hole 521 is L2, and the length of the third branch hole 531 is L3.

[0074] Among them, L1, L2 and L3 satisfy the following relationship: L1>L2>L3.

[0075] The longer length L1 of the first orifice section 511 provides sufficient space for the acceleration of the lubricating oil, ensuring that the lubricating oil can reach a high flow rate in the converging channel, creating favorable conditions for subsequent atomization. In contrast, the shorter length L2 of the second orifice section 521 helps the lubricating oil remain stable at high speeds, avoiding poor atomization or impact wear caused by excessively high flow rates. Finally, the shortest length L3 of the third orifice section 531 ensures that the lubricating oil can rapidly diffuse and atomize before reaching the oil outlet 23, forming a fine and dense droplet distribution, improving atomization quality and efficiency.

[0076] By utilizing the length relationship L1>L2>L3, the embodiments of this application can effectively control the power consumption during the lubricating oil injection process. Since the first orifice 511 is the longest, it provides ample space for energy conversion, transforming the potential energy of the lubricating oil into kinetic energy. The gradual shortening of the second and third orifice portions 521 and 531 reduces friction between the lubricating oil and the orifice wall during high-speed flow, thus lowering power consumption. Simultaneously, the rapid atomization process ensures that the lubricating oil is dispersed in the most energy-efficient manner, without generating unnecessary oil agitation.

[0077] The length difference between the first orifice 511 and the second orifice 521 helps to form a more stable lubricating oil film. The longer first orifice 511 ensures a smooth transition in lubricating oil acceleration, while the adjusted length of the second orifice 521 helps to precisely control the flow rate and pressure of the lubricating oil, avoiding interference from excessively fast or slow flow rates on oil film formation. Finally, the short length of the third orifice 531 causes droplets to be rapidly deposited on the back of the moving scroll disk 2 and the inner support surface 31 of the bracket 3, forming a uniform and dense oil film and reducing mechanical wear.

[0078] The proportional relationship of the lengths of each segment of the nozzle 51, especially the short length L3 of the third segment 531, helps to optimize the excess lubricating oil recovery process. The uniform distribution of droplets on the back side 21 of the moving vortex disk and the inner support surface 31 of the bracket 3 reduces oil residue, allowing excess atomized lubricating oil to flow more quickly along the bracket wall to the return oil hole 33. This avoids excessive accumulation of oil in the oil sump 32, reduces the additional power consumption caused by oil agitation, and also ensures efficient recycling of lubricating oil.

[0079] Furthermore, the diameter of the oil outlet 23 is R1, and the diameter of the first branch hole 511 is R2;

[0080] R1 and R2 satisfy the following relationship: R1>R2.

[0081] Because the diameter R2 of the first branch orifice 511 of the nozzle 51 is relatively small, the lubricating oil accelerates and reaches a high flow rate when passing through this part. When the lubricating oil is sprayed from the first branch orifice 511 to the oil outlet 23, because the diameter R1 of the oil outlet 23 is significantly larger than R2, the lubricating oil suddenly and rapidly diffuses, forming tiny and dense droplets, thus achieving a better atomization effect. This design ensures that the lubricating oil can uniformly cover the back of the moving scroll disk 2 and the inner support surface 31 of the bracket 3 in a mist form, improving lubrication efficiency.

[0082] The design of having a larger diameter R1 for the oil outlet 23 than the diameter R2 for the first branch hole 511 reduces the fluid resistance of the lubricating oil as it passes through the oil outlet 23. During the rotational translation of the moving scroll 2, the energy consumption from the collision between the bearing section 22 and the atomized lubricating oil in the oil sump 32 is much lower than that from directly agitating the liquid oil. The smaller R2 ensures sufficient power to propel the lubricating oil through the nozzle 51 under the pressure of the lubricating oil in the oil storage space 6, while the larger R1 helps reduce the energy consumption when high-speed lubricating oil is sprayed onto the back side 21 of the moving scroll 23.

[0083] Furthermore, there are multiple oil outlet holes 23, which are arranged circumferentially around the axis of the bearing portion 22;

[0084] The spray component 5 is a ring-shaped component with multiple spray holes 51. The multiple spray holes 51 are arranged one-to-one with the multiple oil outlet holes 23 and are interconnected.

[0085] The circumferential distribution of multiple oil outlet holes 23, combined with the multiple spray holes 51 on the annular spray element 5, ensures uniform spraying of lubricating oil after atomization. This design allows the back surface 21 of the moving scroll plate and the inner support surface 31 of the bracket 3 to obtain consistent lubrication coverage, avoiding local over-lubrication or under-lubrication, and improving the uniformity and effectiveness of lubrication within the entire compressor system.

[0086] Because multiple nozzles 51 can perform atomization operations simultaneously, lubricating oil can be sprayed onto key contact surfaces with higher efficiency and a wider coverage area, forming a thin and uniform oil film.

[0087] This design, by increasing the number of nozzles 51, disperses the injection pressure of a single nozzle 51, reducing the additional power consumption required for large-scale oil atomization caused by localized high pressure. The combined effect of multiple nozzles 51 also improves the controllability of the atomization process.

[0088] Furthermore, along the flow direction of the lubricating oil in the oil supply channel 41, the oil outlet 23 is provided at the end relatively away from the bearing portion 22, and the spray hole 51 is provided in the middle of the spray member 5, so that when the spray hole 51 is connected to the oil outlet 23, the axis of the spray hole 51 coincides with the axis of the oil outlet 23.

[0089] When the axis of the nozzle 51 coincides with the axis of the oil outlet 23, the lubricating oil can maintain a straight flow during the injection process, reducing turning and collision in the flow path, thereby reducing fluid energy loss. This straight injection structure improves atomization efficiency, allowing the lubricating oil to cover the back of the moving vortex disk 2 and the inner support surface 31 of the bracket 3 in a more uniform form, forming a uniform and dense oil film, which effectively enhances the lubrication effect.

[0090] Precise alignment of the axes ensures that lubricating oil is delivered directly and efficiently to the contact surfaces of the moving scroll 2 and the support 3, reducing lubricant waste during transmission. This helps form a stable oil film in critical friction areas, significantly reducing wear caused by direct contact between the moving scroll 2 and the support 3.
