Description

Technical Field

[0001] The present invention relates to the technical field of compressors, and in particular to a scroll compressor and an air conditioner having the same. Background Art

[0002] Scroll compressors, a key fluid machine in modern refrigeration and air-conditioning systems, operate by compressing gas within a variable-volume compression chamber formed by the meshing of an orbiting scroll and a stationary scroll. The orbiting scroll is driven by the crankshaft, and its vortex meshes closely with that of the stationary scroll. As the orbiting scroll rotates and translates, the volume of the compression chamber gradually decreases, forcing the gas within the chamber to be compressed to a high-pressure state. However, the high-speed rotation and translation of the orbiting scroll on the inner support surface of the frame causes significant friction between the back of the orbiting scroll and the inner support surface. Over long periods of operation, this friction causes wear on the scroll and frame surfaces, thereby affecting the efficiency and life of the compressor.

[0003] Traditional scroll compressor lubrication typically involves accumulating lubricating oil in an oil sump within the chassis. The orbiting scroll, through its rotation and movement, delivers the oil to areas requiring lubrication, forming an oil film to reduce friction and wear. However, this oil supply method presents a significant problem: the rotating bearing of the orbiting scroll stirs the lubricating oil within the sump, resulting in significant oil stirring power consumption. This not only wastes energy but can also cause the lubricating oil to heat up, affecting its viscosity and lubricating effectiveness, thereby reducing the overall efficiency of the compressor. Summary of the Invention

[0004] The main purpose of the present 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 directly stirring liquid lubricating oil in existing scroll compressors in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a scroll compressor is provided, comprising a fixed scroll, an orbiting scroll, a crankshaft for driving the orbiting scroll, and a bracket, wherein the crankshaft has an oil supply passage extending along its axial direction. The scroll compressor further comprises:

[0006] A spray element, wherein the spray element is provided with a spray hole;

[0007] A bearing portion is provided at one end of the orbiting scroll close to the crankshaft, an oil outlet hole is provided on the bearing portion, and at least a portion of the spray element is provided in the bearing portion so that the oil outlet hole is connected to the spray hole;

[0008] Among them, an oil storage space is formed between the top end of the crankshaft and the inner wall surface of the bearing part, and the oil storage space is connected to the spray hole, so that under the action of continuously transporting lubricating oil into the oil storage space, the lubricating oil in the oil storage space enters the oil outlet hole from the spray hole and is sprayed out from the oil outlet hole.

[0009] Furthermore, the spray hole includes: a first sub-hole portion, one end of the first sub-hole portion is used to communicate with the oil storage space, and an end of the first sub-hole portion away from the oil storage space is used to communicate with the oil outlet hole;

[0010] Wherein, along the spraying direction of the lubricating oil, the diameter of the first sub-hole portion gradually decreases.

[0011] Furthermore, the spray hole includes: a second sub-hole portion, one end of the second sub-hole portion is connected to an end of the first sub-hole portion away from the oil storage space;

[0012] The diameter of the first sub-hole portion is constant along the spraying direction of the lubricating oil.

[0013] Furthermore, the spray hole further comprises: a third sub-hole portion, one end of the third sub-hole portion is connected to an end of the second sub-hole portion away from the first sub-hole portion, and the other end of the third sub-hole portion is connected to the oil outlet hole;

[0014] The diameter of the third sub-hole portion gradually increases along the spraying direction of the lubricating oil.

[0015] Furthermore, along the spraying direction of the lubricating oil, the length of the first sub-hole portion is L1, and the length of the second sub-hole portion is L2;

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

[0017] Furthermore, along the spraying direction of the lubricating oil, the length of the first sub-hole portion is L1, the length of the second sub-hole portion is L2, and the length of the third sub-hole portion is L3;

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

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

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

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

[0022] The spray element is an annular component with a plurality of spray holes, and the plurality of spray holes are arranged in one-to-one correspondence with the plurality of oil outlet holes and are interconnected.

[0023] Furthermore, along the flow direction of the lubricating oil in the oil supply channel, the oil outlet hole is arranged relatively away from the end of the bearing part, and the spray hole is arranged in the middle of the spray element, so that when the spray hole is connected to the oil outlet hole, the axis of the spray hole coincides with the axis of the oil outlet hole.

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

[0025] The technical solution of the present invention connects the oil storage space with the spray holes, ensuring that lubricating oil can be effectively accumulated and maintained at high pressure. When the pressure in the oil storage space reaches a certain level, the lubricating oil is sprayed through the spray holes at high speed, forming fine droplets that evenly coat the back of the orbiting scroll and the inner support surface of the bracket, forming a stable oil film. This oil film effectively reduces direct contact and wear between the orbiting scroll and the bracket, thereby improving the operational stability and service life of the scroll compressor.

[0026] The use of atomized oil supply instead of traditional liquid oil supply reduces the energy consumption of the orbiting scroll bearing in the oil pool. Because the resistance of the mist droplets is much smaller than that of liquid oil, the orbiting scroll moves more smoothly, reducing frictional power consumption during operation, thereby improving the overall energy efficiency of the scroll compressor.

[0027] Through the connection design between the oil outlet hole and the spray hole, excess mist lubricating oil droplets can flow along the wall of the bracket and eventually be discharged from the oil return hole, avoiding excessive accumulation of lubricating oil in the bracket oil pool and reducing oil evaporation and pollution.

[0042] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] As mentioned in the background art, the present application provides a scroll compressor and an air conditioner having the same to solve the problem of high power consumption caused by directly stirring liquid lubricating oil in existing scroll compressors in the prior art.

[0044] Example 1

[0045] like Figures 1 to 6 As shown, an embodiment of the present application provides a scroll compressor, comprising a fixed scroll 1, an orbiting scroll 2, a crankshaft 4 for driving the orbiting scroll 2, and a bracket 3. The crankshaft 4 has an oil supply passage 41 extending along its axial direction. The scroll compressor further comprises:

[0046] A spray element 5, wherein a spray hole 51 is provided on the spray element 5;

[0047] The bearing portion 22 is disposed at one end of the orbiting scroll 2 close to the crankshaft 4. The bearing portion 22 is provided with an oil outlet hole 23. At least a portion of the spray element 5 is disposed within the bearing portion 22 so that the oil outlet hole 23 is in communication with the spray hole 51.

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

[0049] The scroll compressor provided in the embodiments of the present application achieves effective atomization of lubricating oil by disposing a spray element 5 within the bearing portion 22 of the orbiting scroll 2 and configuring a spray hole 51 within the spray element 5. Specifically, when lubricating oil is input into the oil reservoir 6 via the oil supply passage 41 within the crankshaft 4, the lubricating oil pressure within the oil reservoir 6 directly communicates with the spray hole 51. The lubricating oil then enters the spray hole 51, from which it enters the oil outlet hole 23 of the bearing portion 22, ultimately being sprayed onto the back surface 21 of the orbiting scroll and the inner support surface of the bracket 3.

[0050] During the orbiting scroll 2's translational rotation, its bearing 22 no longer directly contacts the liquid lubricant, but instead collides with atomized lubricant particles. Because the drag of the atomized droplets is much smaller than that of the liquid oil, the oil stirring power generated by the bearing 2 of the orbiting scroll 2 is significantly reduced, improving the compressor's energy efficiency.

[0051] The lubricating oil is evenly covered on the back surface 21 of the movable scroll and the inner supporting surface 31 of the bracket 3 in the form of atomization, forming a stable oil film layer, which effectively reduces direct contact and friction, improves the lubrication uniformity and effect, delays component wear, and increases the service life of the scroll compressor.

[0052] Through the precise control of the spray element 5, excessive lubricating oil is prevented from being retained in the oil pool 32. Excess lubricating oil droplets can flow smoothly along the wall of the bracket 3 to the oil return hole 33 at the bottom and be recycled, thereby reducing waste, maintaining a clean environment in the oil pool 32, and further reducing the additional power consumption caused by oil agitation.

[0053] Furthermore, the spray hole 51 includes: a first sub-hole portion 511, one end of the first sub-hole portion 511 is used to communicate with the oil storage space 6, and an end of the first sub-hole portion 511 away from the oil storage space 6 is used to communicate with the oil outlet hole 23;

[0054] The diameter of the first sub-hole portion 511 gradually decreases along the spraying direction of the lubricating oil.

[0055] The diameter of the first sub-hole portion 511 gradually decreases along the direction of lubricating oil spraying. This design increases the flow resistance of the lubricating oil in the spray hole 51, causing the lubricating oil flowing through this part to accelerate. The increase in flow rate leads to a drop in pressure. When the lubricating oil rushes out of the narrowest part of the spray hole 51 at high speed, due to the sudden open space it encounters, the shear force of the fluid causes the lubricating oil to diffuse rapidly, forming tiny droplets, significantly enhancing the atomization effect of the oil supply. The atomized lubricating oil particles are more widely dispersed, covering a larger area of ​​the back surface 21 of the movable scroll disk and the inner support surface 31 of the bracket 3, making lubrication more uniform and improving the overall lubrication efficiency.

[0056] The direct connection between the oil storage space 6 and the first sub-hole portion 511 ensures the smooth flow of the lubricating oil under high pressure, and the tapered first sub-hole portion 511 effectively avoids the movable scroll 2 from directly stirring a large amount of liquid oil when rotating and translating, reducing the direct contact area between the bearing portion 22 and the lubricating oil, thereby significantly reducing the additional power consumption caused by the stirring of the lubricating oil.

[0057] Through precise control of the first aperture portion 511, atomized lubricating oil particles are accurately sprayed into the oil outlet 23 and evenly distributed across the orbiting scroll back 21 and the inner support surface 31 of the bracket 3, reducing disordered flow and waste of lubricating oil. During the translational motion of the orbiting scroll 2, excess lubricating oil droplets flow along the wall of the bracket 3 to the oil return hole 33 for timely recovery, preventing excessive accumulation in the oil pool 32. This further reduces power consumption and improves the recycling rate of the lubricating oil.

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

[0059] Furthermore, the spray hole 51 includes: a second sub-hole portion 521 , one end of the second sub-hole portion 521 being connected to an end of the first sub-hole portion 511 away from the oil storage space 6 ;

[0060] The diameter of the first divided hole portion 511 is constant along the spraying direction of the lubricating oil.

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

[0062] By dividing the spray hole 51 into a tapered first sub-hole portion 511 and a constant-diameter second sub-hole portion 521, the present embodiment can precisely control the flow of lubricating oil from the oil reservoir 6 to the back surface 21 of the orbiting scroll. The tapered design of the first sub-hole portion 511 ensures sufficient atomization, while the constant diameter of the second sub-hole portion 521 helps control the flow rate, reducing the risk of increased power consumption caused by excessive atomization or excessive flow rate.

[0063] The second sub-hole portion 521 of constant diameter provides a stable atomization injection channel for the lubricating oil, avoiding the fluid dynamic instability caused by the change of the aperture, ensuring that the lubricating oil covers the back side 21 of the movable scroll plate and the inner supporting surface 31 of the bracket 3 in the best state, enhancing the lubrication efficiency, reducing wear, and thereby improving the operating stability and service life of the scroll compressor.

[0064] The combined design of the first sub-hole portion 511 and the second sub-hole portion 521 optimizes the distribution and flow of the lubricating oil in the bearing portion 22 of the orbiting scroll 2, so that excess lubricating oil droplets can flow more smoothly to the wall of the bracket 3 and eventually be discharged from the oil return hole 33, thereby improving the recycling of the lubricating oil, reducing the residence time of the oil in the oil pool 32, further reducing power consumption, and improving energy utilization efficiency.

[0065] Furthermore, the spray hole 51 further includes: a third sub-hole portion 531 , one end of the third sub-hole portion 531 is connected to an end of the second sub-hole portion 521 away from the first sub-hole portion 511 , and the other end of the third sub-hole portion 531 is connected to the oil outlet 23 ;

[0066] The diameter of the third sub-hole portion 531 gradually increases along the spraying direction of the lubricating oil.

[0067] The lubricating oil is accelerated from the oil storage space 6 through the first sub-hole portion 511, and the flow rate stabilizes at a high level when entering the second sub-hole portion 521. When flowing through the gradually expanding third sub-hole portion 531, the fluid pressure drops rapidly due to the sudden increase in the flow area, prompting the high-speed lubricating oil to diffuse rapidly at the outlet, forming a large number of fine droplets.

[0068] The gradually expanding third sub-hole portion 531 not only reduces the resistance encountered by the lubricating oil during injection, thus lowering the power consumption of the bearing portion of the orbiting scroll 2, but also reduces the direct contact area between the lubricating oil, the orbiting scroll back surface 21, 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 gradually expanding design of the third sub-hole portion 531 helps to form a more solid and uniform oil film on the back surface 21 of the orbiting scroll and the inner supporting surface 31 of the bracket 3 .

[0070] During the translation and rotation of the orbiting scroll 2, excess misted lubricating oil droplets can more easily flow along the wall of the bracket 3 to the oil return hole 33, promoting the recycling of the lubricating oil. This design prevents excessive accumulation of oil in the oil pool 32 and reduces energy loss caused by oil agitation. Furthermore, the optimized design of the spray hole 51 allows for more concentrated and efficient atomization of the lubricating oil, reducing unnecessary evaporation and loss.

[0071] Furthermore, along the spraying direction of the lubricating oil, the length of the first divided hole portion 511 is L1, and the length of the second divided hole portion 521 is L2;

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

[0073] Furthermore, along the spraying direction of the lubricating oil, the length of the first sub-hole portion 511 is L1, the length of the second sub-hole portion 521 is L2, and the length of the third sub-hole portion 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 sub-hole 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 tapered channel, creating favorable conditions for subsequent atomization. In contrast, the shorter length L2 of the second sub-hole section 521 can help the lubricating oil remain stable at high speeds, avoiding poor atomization or impact wear caused by excessively fast flow rates. Finally, the shortest length L3 of the third sub-hole section 531 ensures that the lubricating oil can quickly diffuse and atomize before reaching the oil outlet 23, forming a fine and dense distribution of droplets, thereby improving the quality and efficiency of atomization.

[0076] By adopting the length relationship of L1 > L2 > L3, the embodiment of the present application can effectively control the power consumption during the lubricating oil injection process. Since the first sub-hole portion 511 is the longest, it provides ample space for energy conversion, converting the potential energy of the lubricating oil into kinetic energy. The gradual shortening of the second sub-hole portion 521 and the third sub-hole portion 531 reduces the friction between the lubricating oil and the hole wall during high-speed flow, reducing power consumption. At the same time, the rapid atomization process ensures that the lubricating oil is dispersed in the most energy-efficient manner, without causing unnecessary oil agitation.

[0077] The difference in length between the first and second sub-holes 511, 521, helps form a more stable lubricating oil film. The longer first sub-hole 511 ensures a smooth transition in the acceleration of the lubricating oil, while the adjustable length of the second sub-hole 521 helps precisely control the flow rate and pressure of the lubricating oil, preventing excessively fast or slow flow from disrupting the oil film. Finally, the shorter length of the third sub-hole 531 encourages droplets to quickly deposit on the back of the orbiting scroll 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 lengths of each sub-portion of the spray hole 51, particularly the short length L3 of the third sub-portion 531, help optimize the recovery process for excess lubricating oil. The even distribution of droplets on the orbiting scroll back surface 21 and the inner support surface 31 of the bracket 3 reduces oil residue and allows excess mist lubricating oil to flow more quickly along the bracket wall toward the oil return hole 33. This prevents excessive oil accumulation in the oil pool 32, reduces the additional power consumption caused by oil agitation, and ensures efficient recycling of the lubricating oil.

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

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

[0081] Because the diameter R2 of the first sub-hole portion 511 of the spray hole 51 is relatively small, the lubricating oil accelerates and reaches a higher flow rate when passing through this portion. When the lubricating oil is sprayed from the first sub-hole portion 511 to the oil outlet hole 23, because the diameter R1 of the oil outlet hole 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 evenly covers the back surface of the orbiting scroll 2 and the inner support surface 31 of the bracket 3 in the form of a mist, improving lubrication efficiency.

[0082] The design of the oil outlet hole 23 with a diameter R1 greater than the diameter R2 of the first sub-hole portion 511 reduces the fluid resistance of the lubricating oil passing through the oil outlet hole 23. During the orbiting scroll 2's translational rotation, the power consumption of the collision between the bearing portion 22 and the misted lubricating oil in the oil pool 32 is much lower than that of directly stirring the liquid oil. The smaller R2 ensures that the pressure of the lubricating oil in the oil storage space 6 provides sufficient power to propel the lubricating oil through the spray hole 51, while the larger R1 helps reduce the power consumption of the high-speed lubricating oil when it is sprayed onto the back surface 21 of the orbiting scroll.

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

[0084] The spray element 5 is an annular component, and has a plurality of spray holes 51 . The plurality of spray holes 51 are arranged in a one-to-one correspondence with the plurality of oil outlet holes 23 and are interconnected.

[0085] The circumferential distribution of multiple oil outlet holes 23, combined with the multiple spray holes 51 in the annular spray element 5, ensures uniform spraying of the atomized lubricating oil. This design ensures consistent lubrication coverage of the orbiting scroll back surface 21 and the inner support surface 31 of the bracket 3, avoiding localized over-lubrication or under-lubrication, and improving the uniformity and effectiveness of lubrication throughout the compressor system.

[0086] Since the multiple spray holes 51 can perform atomization operations simultaneously, the lubricating oil can be sprayed onto the key contact surface with higher efficiency and a wider coverage area, forming a thin and uniform oil film.

[0087] This design disperses the injection pressure of each nozzle 51 by increasing the number of nozzles 51, reducing the additional power consumption required for large-scale oil atomization caused by local 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 hole 23 is arranged relatively away from the end of the bearing portion 22, and the spray hole 51 is arranged in the middle of the spray element 5, so that when the spray hole 51 is connected to the oil outlet hole 23, the axis of the spray hole 51 coincides with the axis of the oil outlet hole 23.

[0089] When the axis of the spray hole 51 coincides with the axis of the oil outlet hole 23, the lubricating oil maintains a straight flow during injection, reducing diversion and collisions in the flow path, thereby reducing fluid energy loss. This linear injection structure improves atomization efficiency, allowing the lubricating oil to more evenly coat the back surface of the orbiting scroll 2 and the inner support surface 31 of the bracket 3, forming a uniform and dense oil film, effectively enhancing the lubrication effect.

[0090] Precise axis alignment ensures direct and efficient transfer of lubricating oil to the contact surface between the orbiting scroll 2 and the bracket 3, reducing lubricant waste during transfer. This helps form a stable oil film in the critical friction area, significantly reducing wear and tear caused by direct contact between the orbiting scroll 2 and the bracket 3.
