Description

Technical Field

[0001] This invention belongs to the field of compressor technology, specifically relating to a compressor and an air conditioning system having the compressor. Background Technology

[0002] With the development of variable frequency technology, the operating frequency of scroll compressors is constantly increasing. At high frequencies, the pump body of the scroll compressor requires more oil to ensure lubrication and sealing. Currently, most scroll compressors supply oil via an oil pump at the bottom of the crankshaft, and the oil supply is directly proportional to the rotational speed. As the operating frequency increases, the amount of oil entering the pump body increases rapidly, but this also leads to a rapid increase in the oil content of the refrigerant gas discharged from the pump body. If this is not controlled, it will result in an increased oil discharge rate from the compressor, affecting the overall performance of the refrigeration system. Furthermore, if the oil inside the compressor cavity does not flow back to the oil sump at the bottom of the compressor in a timely manner, it will cause oil shortage in the compressor, affecting the reliability of the scroll compressor. Therefore, it is necessary to enhance the ability of the scroll compressor to separate oil droplets from the refrigerant gas and to return the oil to the oil sump.

[0003] Traditional vertical scroll compressors do not involve a separate oil-gas separation structure. After leaving the compression chamber, the refrigerant flows along the inner wall of the compressor casing, causing oil droplets to be adsorbed onto the wall surface, thus achieving oil-gas separation. The separated refrigerant gas is then discharged through the compressor's exhaust pipe. The separated oil flows downwards in the form of an oil film under the influence of gravity, but the flow rate is relatively slow. However, due to the limited oil adsorption capacity of the wall surface and the limitation of oil return capacity, the thickness of the oil film on the wall surface will reach a maximum value. At this point, it is impossible to further adsorb oil droplets, resulting in the oil content of the refrigerant gas not being able to decrease further.

[0004] See also Figure 1 As shown, existing oil-gas separation methods involve adjusting the location of the exhaust channel or adding a guide vane structure to prevent oil-containing refrigerant gas from being directly discharged from the exhaust pipe after leaving the compression chamber. This is achieved by increasing the distance the refrigerant gas travels within the compressor housing to enhance the oil adsorption and separation effect on the wall. The refrigerant gas enters the upper and lower chambers of the motor through different channels before moving to the exhaust pipe for discharge, resulting in a relatively long trajectory. However, this method has limited oil separation effectiveness, especially under high-frequency compressor operation. Summary of the Invention

[0005] This invention provides a compressor and an air conditioning system having the compressor, which can solve the technical problem of poor oil separation effect in existing oil-gas separation methods.

[0006] This invention provides a compressor, which includes a crankshaft and a stator coil, and also includes a flow guide;

[0007] The guide vane is connected to the crankshaft, and the crankshaft drives the guide vane to rotate. The guide vane is used to guide the refrigerant to the stator coil.

[0008] In some embodiments, the inner side of the flow guide has inner blades for pushing the refrigerant to flow into the stator coil.

[0009] In some embodiments, the outer side of the flow guide has outer blades that push the refrigerant flow in the opposite direction to the direction pushed by the inner blades. The outer blades are used to accelerate the discharge of refrigerant from the compressor.

[0010] In some implementations, the inner and outer blades are tilted at opposite angles.

[0011] In some embodiments, the guide includes a connecting ring and a partition ring, the connecting ring being disposed inside the partition ring and connected to the crankshaft;

[0012] The connecting ring is circumferentially spaced with multiple inner blades. One end of each inner blade is connected to the inner wall of the connecting ring, and the other end of each inner blade is connected to the partition ring.

[0013] The separator ring is circumferentially spaced with multiple outer blades, which are connected to the outer wall of the connecting ring.

[0014] In some implementations, a first refrigerant flow path is formed during the rotation of the outer blades, and a second refrigerant flow path is formed during the rotation of the inner blades. The refrigerant in the second refrigerant flow path first flows into the stator coil and then into the first refrigerant flow path.

[0015] In some embodiments, a housing is also included, the housing having a first chamber and a second chamber, a flow guide being located in the first chamber, refrigerant in the first refrigerant flow path flowing into the first chamber and then out, and refrigerant in the second refrigerant flow path flowing sequentially through the stator coil and the second chamber, then flowing back into the first refrigerant flow path and out of the first chamber.

[0016] In some embodiments, a balance block is also included, and the balance block, the guide element, and the stator coil are arranged sequentially along the axial direction of the crankshaft, or the guide element, the balance block, and the stator coil are arranged sequentially along the axial direction of the crankshaft.

[0017] In some implementations, the inner diameter of the separator ring is larger than the outer diameter of the stator coil.

[0018] In some embodiments, an exhaust pipe is provided on the housing, and the opening of the exhaust pipe is lower than the top of the guide member.

[0019] In some embodiments, the flow guide has an air inlet side, on which a flow guide plate is provided to guide the refrigerant to the inside of the flow guide.

[0020] In some embodiments, the deflector includes a retaining ring and a deflector shroud connected to each other, the retaining ring being connected to the inner wall of the housing, and the deflector being arranged around the crankshaft and extending into the deflector.

[0021] In some implementations, the fixing ring has a flared structure, and the flow guide has a constricted structure.

[0022] An air conditioning system includes a compressor, wherein the compressor is the compressor described above.

[0023] The present invention provides a compressor and an air conditioning system having the compressor, which have the following beneficial effects:

[0024] During crankshaft rotation, the guide vanes rotate synchronously, directing the refrigerant to the stator coil. The stator coil is made of fine copper wire repeatedly wound around the stator core, forming a porous structure with a large surface area. When oil-containing refrigerant passes through the stator coil, its large surface area adsorbs a large number of oil droplets, which then aggregate into large droplets that fall with gravity. This invention, by setting up guide vanes, allows the refrigerant to flow concentratedly onto the stator coil, ensuring full contact between the refrigerant and the porous coil. This allows the refrigerant to adsorb and separate oil on the surface of the stator coil, reducing the oil content of the refrigerant. This enhances oil-gas separation and accelerates oil return to the oil sump, thereby reducing compressor oil discharge rate and improving the energy efficiency of the air conditioning system.

[0043] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0044] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0047] See also Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, a compressor is provided, the compressor including a crankshaft 5 and a stator coil 6, and also including a flow guide 1; the flow guide 1 is connected to the crankshaft 5, and the crankshaft 5 drives the flow guide 1 to rotate, the flow guide 1 is used to guide the refrigerant to the stator coil 6.

[0048] During the rotation of crankshaft 5, the guide component 1 rotates synchronously, guiding the refrigerant to the stator coil 6. The stator coil 6 is formed by repeatedly winding fine copper wire around the stator core 13, creating a porous structure with a large surface area. When oil-containing refrigerant passes through the stator coil 6, its large surface area adsorbs a large number of oil droplets from the refrigerant, which then aggregate into large oil droplets that fall with gravity. This invention, by setting the guide component 1, allows the refrigerant to flow concentratedly onto the stator coil 6, ensuring sufficient contact between the refrigerant and the porous stator coil 6. This allows the refrigerant to adsorb and separate oil on the surface of the stator coil 6, reducing the oil content of the refrigerant. This enhances the oil-gas separation capability and accelerates the return of oil to the oil sump 16, thereby reducing the compressor's oil discharge rate and improving the energy efficiency of the air conditioning system.

[0049] See also Figure 4 and Figure 5 The inner side of the flow guide 1 has an inner blade 101, which is used to push the refrigerant to flow to the stator coil 6.

[0050] The outer side of the flow guide 1 has an outer blade 102. The outer blade 102 pushes the refrigerant to flow in the opposite direction to the inner blade 101. The outer blade 102 is used to accelerate the discharge of refrigerant from the compressor.

[0051] In this embodiment, during the rotation of the guide vane 1, the inner blade 101 rotates synchronously, generating thrust on the refrigerant flowing into the inner blade 101, pushing the refrigerant to continue flowing in the intake direction. Simultaneously, the outer blade 102 also rotates synchronously. Due to the different positions of the outer and inner blades 101, it generates thrust on the refrigerant flowing into the outer blade 102, pushing the refrigerant to flow in the opposite direction to the intake direction. This invention, by setting two layers of blades, allows the blades to generate thrust, thereby enabling the inner blade 101 and outer blade 102 to produce refrigerant flowing in opposite directions. It has a simple structure, a wider range of applications, and can meet different gas flow requirements.

[0052] The inner blade 101 and the outer blade 102 are inclined and have opposite tilt angles.

[0053] See also 6 and Figure 7 As shown, in one specific implementation, the outer side of the inner blade 101 has an inclination angle of less than 0° with the horizontal direction, and the outer side of the outer blade 102 has an inclination angle of greater than 0° with the horizontal direction. Due to the existence of the inclination angle, the refrigerant flows to the guide member 1 and generates bidirectional flow, which can meet different refrigerant flow direction requirements.

[0054] The flow guide 1 includes a connecting ring 103 and a partition ring 104. The connecting ring 103 is disposed inside the partition ring 104 and is connected to the rotating shaft. The connecting ring 103 is circumferentially spaced with a plurality of inner blades 101. One end of the plurality of inner blades 101 is connected to the inner wall of the connecting ring 103, and the other end of the plurality of inner blades 101 is connected to the partition ring 104. The partition ring 104 is circumferentially spaced with a plurality of outer blades 102. The plurality of outer blades 102 are connected to the outer wall of the connecting ring 103.

[0055] In this embodiment, the connecting ring 103 serves to mount the inner blade 101 and connect to the rotating shaft, while the baffle separates the refrigerant flowing into the inner blade 101 and the outer blade 102. When the air intake direction is downward, as the refrigerant flows into the inner blade 101 and rotates, due to the tilt angle, the refrigerant flows onto the inner blade 101, where centrifugal force pushes it downward, while the refrigerant flowing onto the outer blade 102 is pushed upward. This invention, by tilting the inner blade 101 and outer blade 102, combined with the centrifugal force generated during the rotation of the guide member 1, produces two refrigerants flowing in opposite directions, thus extending the refrigerant's flow path.

[0056] See also Figure 8 and Figure 12 As shown, the outer blade 102 forms a first refrigerant flow path 21 during rotation, and the inner blade 101 forms a second refrigerant flow path 22 during rotation. The refrigerant in the second refrigerant flow path 22 first flows into the stator coil 6 and then flows into the first refrigerant flow path 21.

[0057] In this embodiment, taking the compressor as vertically mounted as an example, during the rotation of the guide vane 1, the refrigerant flows downwards. The inner blades 101 push the refrigerant downwards to form a second refrigerant flow path 22. The refrigerant in the second refrigerant flow path 22 continues to flow downwards. After passing through the stator coil 6, the refrigerant continues to flow downwards into the gap between the stator core 13 and the rotor 15. Under the action of the outer blades 102, the refrigerant is driven upwards, thereby drawing the refrigerant entering the motor into the first refrigerant flow path 21.

[0058] Under the impingement of the inner blades 101, the refrigerant in the second refrigerant flow path 22 first passes through the stator coil 6. The stator coil 6 is formed by repeatedly winding fine copper wire around the stator core 13, creating a porous structure with a large surface area. When the oil-containing refrigerant passes through the stator coil 6, its extremely large surface area will adsorb oil droplet particles in the refrigerant, which will then aggregate into large oil droplets and fall with gravity. This invention changes the flow path of the refrigerant through the guide component 1, thereby enhancing the oil-gas separation capability and accelerating the return of oil to the oil sump 16, thus reducing the oil discharge rate of the scroll compressor and improving the energy efficiency of the air conditioning system. In addition, since the refrigerant in the second refrigerant flow path 22 moves vertically downwards, the flow path of the refrigerant is extended and is in the same direction as the falling of the large oil droplets, which also promotes the discharge of oil droplets during the refrigerant flow.

[0059] It also includes a housing 3, which has a first chamber 301 and a second chamber 302. The guide 1 is located in the first chamber 301. The refrigerant in the first refrigerant flow path 21 flows into the first chamber 301 and is discharged. The refrigerant in the second refrigerant flow path 22 flows through the stator coil 6 and the second chamber 302 in sequence, and then flows into the first refrigerant flow path 21 and is discharged from the first chamber 301.

[0060] In one specific implementation, the compressor of the present invention is a scroll compressor. The crankshaft 5, which cooperates with the rotor 15 of the motor, rotates to drive the moving scroll 12 to make a circular motion. The moving scroll 12 meshes with the stationary scroll 11 to compress the refrigerant. The first chamber 301 is located above the second chamber 302. The first chamber 301 is connected to the exhaust chamber 9. The compressed refrigerant flows from the exhaust chamber 9 into the first chamber 301 through the channel between the stationary scroll 11 and the side of the upper support 10. After oil-gas separation begins in the first chamber 301, the refrigerant is discharged.

[0061] In this embodiment, a stator flow groove 14 is formed between the inner wall of the housing 3 and the outer wall of the stator core 13. The refrigerant in the second refrigerant flow path 22 flows through the gap between the stator coil 6, the stator core 13, and the rotor 15 into the second chamber 302. In the second chamber 302, oil droplets continue to fall into the oil pool 16 below due to inertia, while the refrigerant is deflected towards the stator flow groove 14 and flows into the first refrigerant flow path 21 by the rising airflow generated by the outer blades 102, thereby being carried back to the first chamber 301. During the process of the refrigerant entering the second chamber 302 from the first chamber 301 and returning to the first chamber 301, the oil content of the refrigerant decreases significantly. In addition, the refrigerant also carries away the heat generated by the stator during the process of passing through the stator coil 6, which can effectively reduce the temperature of the motor. Moreover, when the refrigerant passes through the porous stator coil 6 and enters the second chamber 302, the velocity distribution is more uniform, the impact on the liquid surface of the bottom oil pool 16 is smaller, and the oil splashes into the second chamber 302 are avoided.

[0062] In one specific implementation, the guide vane 1 is arranged in two layers, with opposite blade angles and separated by a partition ring 104. During compressor operation, it forms a downward inner movement and an upward outer movement pattern within the first chamber 301, allowing the upward-flowing low-oil-content refrigerant to be discharged. The guide vane 1 rotates synchronously with the crankshaft 5 through interference fit, bonding, keying, or other methods. Without adding additional transmission components, it propels the refrigerant, allowing more refrigerant to enter the second chamber 302, increasing its movement distance to improve the separation effect, and finally discharging it back into the first refrigerant flow path 21.

[0063] See also Figure 11 It also includes a balance block 4, and the balance block 4, the guide element 1 and the stator coil 6 are arranged sequentially along the axial direction of the crankshaft 5, or the guide element 1, the balance block 4 and the stator coil 6 are arranged sequentially along the axial direction of the crankshaft 5.

[0064] In this embodiment, the flow guide 1 can be set above or below the balance block 4. With a suitable dynamic balance design, setting the flow guide 1 above the balance block 4 will not affect the oil distribution effect of the stator coil 6.

[0065] The inner diameter of the separator ring 104 is larger than the outer diameter of the stator coil 6, so that the airflow inside the stator coil 6 flows downward, which is conducive to the discharge of large oil droplets adsorbed on the stator coil 6.

[0066] An exhaust pipe 7 is provided on the housing 3, and the opening of the exhaust pipe 7 is lower than the top of the guide member 1.

[0067] In this embodiment, in order to prevent the refrigerant flow on the inner blade 101 from being too large at high compressor speed, so that the refrigerant leaks directly to the outlet of the exhaust pipe 7, the opening of the compressor exhaust pipe 7 needs to be lower than the top of the partition, so that the opening of the exhaust pipe 7 is completely in the low oil content refrigerant in the upward refrigerant flow path 21, thereby making the oil content of the refrigerant discharged from the compressor lower and the oil discharge rate of the compressor lower.

[0068] See also Figure 9 and Figure 10 As shown, the flow guide 1 has an air inlet side, and a flow guide plate 8 is provided on the air inlet side. The flow guide plate 8 is used to guide the refrigerant to the inner side of the flow guide 1.

[0069] The guide plate 8 includes a fixed ring 801 and a guide shroud 802 connected to each other. The fixed ring 801 is connected to the inner wall of the housing 3, and the guide shroud 802 is arranged around the rotating shaft and extends into the guide member 1.

[0070] In this embodiment, the guide plate 8 is provided to pour the refrigerant in the exhaust chamber 9 onto the inner blade 101, thereby performing oil separation and reducing the oil discharge rate of the compressor.

[0071] The fixing ring 801 has a flared structure, while the flow guide 802 has a constricted structure.

[0072] In one specific implementation, the retaining ring 801 is an inclined surface that extends upwards from the support 10 and widens, while the guide shroud 802 is an inclined surface that narrows towards the guide member 1. The guide shroud 802 can gather the refrigerant flowing from the exhaust chamber 9 to the center of the guide member 1. The retaining ring 801 has multiple clearance holes circumferentially for welding the guide plate 8 to the inner wall of the housing 3, or it can be fixed by screws or clips.

[0073] An air conditioning system includes a compressor, wherein the compressor is the compressor described above.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the protection scope of the present invention.
