Description

Technical Field

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

[0002] Scroll compressors are widely used in refrigeration, air conditioning, and heat pump industries due to their high efficiency, small size, light weight, and stable operation. Generally, a scroll compressor consists of a sealed casing, a stationary scroll, a moving scroll, a support frame, a crankshaft, an anti-rotation mechanism, an oil supply device, and a motor. Both the moving and stationary scrolls have helical profiles. The moving scroll is eccentrically positioned relative to the stationary scroll, with a 180° angle between them, creating multiple crescent-shaped spaces between them. When the moving scroll rotates around the center of the stationary scroll with a certain radius, the outer crescent-shaped spaces continuously move towards the center. During this process, the refrigerant is gradually pushed towards the central space, its volume continuously decreasing while its pressure continuously increasing until it connects with the central exhaust port. The high-pressure refrigerant is then discharged from the pump body, completing the compression process.

[0003] During compressor operation, the oil flowing through the main bearing in the upper support oil sump mixes with the refrigerant as the balance block rotates; the compressed refrigerant also carries refrigeration oil into the compressor cavity. If this refrigeration oil is not properly guided and separated, it will increase resistance and power consumption when flowing into the gap between the stator and rotor of the running motor, and eventually leave the compressor with the refrigerant, increasing the oil discharge rate. Summary of the Invention

[0004] The purpose of this application is to provide a compressor and an air conditioner having the same, which solves the problems of increased oil discharge rate caused by refrigerant oil flowing out of the compressor with the refrigerant and increased motor resistance and power consumption caused by refrigerant oil entering the gap between the stator and rotor of the motor.

[0005] Therefore, in a first aspect, embodiments of this application provide a compressor, the compressor comprising:

[0006] The housing has a working chamber inside, and the housing is provided with an intake pipe and an exhaust pipe that communicate with the working chamber;

[0007] An upper support is disposed within the working chamber. The upper support is provided with a stationary vortex disk and a moving vortex disk that meshes with the stationary vortex disk. The stationary vortex disk is provided with an exhaust hole. An exhaust channel extending along the height direction of the housing is formed between the stationary vortex disk, the moving vortex disk, the upper support, and the side wall of the housing. The exhaust channel is connected to the exhaust hole and the exhaust pipe.

[0008] A flow guide, disposed within the exhaust channel and located below the upper bracket, includes a first flow guide portion for guiding refrigerant to the exhaust pipe and a second flow guide portion connected to the bottom of the first flow guide portion, wherein the second flow guide portion forms an oil guiding passage with the inner wall of the housing; and

[0009] A balance block is disposed at the bottom of the upper support. An oil baffle is fitted around the outer periphery of the balance block, and an oil inlet cavity is formed between the balance block and the oil baffle. The oil inlet cavity is connected to the oil guide passage through a diversion passage.

[0010] In one possible implementation, the diversion path is connected to the oil guide path through the oil outlet, the second guide portion extends along the height direction of the housing, and the second guide portion is connected to the first guide portion through a connecting end; in the height direction of the housing, the length of the second guide portion is L, and the distance X between the oil outlet and the connecting end satisfies: L / 2 < X < L.

[0011] In one possible implementation, the first drain portion includes a direct current portion extending along the height direction of the housing and an arc flow portion connected to the direct current portion, with one end of the arc flow portion away from the direct current portion connected to the second drain portion; the vent hole of the exhaust pipe is correspondingly provided with the direct current portion.

[0012] In one possible implementation, the distance between the DC section and the inner wall of the housing is greater than the distance between the upper bracket and the inner wall of the housing.

[0013] In one possible implementation, the diversion path is connected to the oil inlet chamber via an oil inlet located at the bottom of the oil baffle.

[0014] In one possible implementation, the cross-section of the diversion path perpendicular to its own axis is circular, and the diameter of the diversion path is smaller than the minimum distance between the oil baffle and the balance block in a first direction, which is perpendicular to the height direction of the housing.

[0015] In one possible implementation, the diversion path includes a first diversion path and a second diversion path that are connected to each other. The first diversion path extends in a direction parallel to the height of the housing, and the second diversion path extends in a direction perpendicular to the height of the housing. The first diversion path is used to communicate with the oil inlet chamber, and the second diversion path is used to communicate with the oil guide passage.

[0016] In one possible implementation, the housing is provided with a drive assembly for driving the moving scroll. The drive assembly includes a drive member and a transmission member disposed in the housing and located below the upper support. One end of the transmission member is connected to the output end of the drive member, and the other end of the transmission member passes through the oil baffle, the balance block and the upper support in sequence along the height direction of the housing and is connected to the moving scroll.

[0017] In one possible implementation, a sealing ring is provided between the bottom of the balance block and the oil baffle, and the sealing ring is disposed around the outer periphery of the transmission component.

The refrigerant oil mixed in the refrigerant is separated from the refrigerant through the second guide member to reduce the oil discharge rate. The refrigerant oil agitated by the balance block is guided by the oil baffle and merged with the refrigerant oil separated from the refrigerant to ensure that the collection channel of the refrigerant oil is singular and to avoid the refrigerant oil flowing freely, which would increase the compressor resistance and increase the compressor internal consumption.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figures 1-5As shown in the figure, this application provides a compressor, including a housing 2, an upper bracket 6, a flow guide 17, and a balance block 8. The housing 2 has a working chamber 7 inside, and an intake pipe 1 and an exhaust pipe 18 communicating with the working chamber 7 are provided on the housing 2. The upper bracket 6 is disposed within the working chamber 7, and has a stationary scroll 3 and a moving scroll 4 meshing with the stationary scroll 3. The stationary scroll 3 has an exhaust port 16. An exhaust channel 11 extending along the height direction of the housing 2 is formed between the stationary scroll 3, the moving scroll 4, and the upper bracket 6 and the side wall of the housing 2. The exhaust channel 11 communicates with the exhaust port 16 and the exhaust pipe 18. The flow guide 17 is disposed within the exhaust channel 11 and located below the upper bracket 6. The flow guide 17 includes a first flow guide portion 171 for guiding refrigerant to the exhaust pipe 18 and a second flow guide portion 172 connected to the bottom of the first flow guide portion 171. An oil guide passage 21 is formed between the second flow guide portion 172 and the inner wall of the housing 2. The balance block 8 is located at the bottom of the upper support 6. An oil baffle 19 is sleeved on the outer periphery of the balance block 8, and an oil inlet cavity 22 is formed between the balance block 8 and the oil baffle 19. The oil inlet cavity 22 is connected to the oil guide passage 21 through the diversion passage 23.

[0030] A compressor, a driven fluid machine that elevates low-pressure gas to high-pressure gas, is the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe 1, compresses it via a piston driven by the motor 10, and then discharges high-temperature, high-pressure refrigerant gas through the exhaust pipe 18, providing power for the refrigeration cycle and thus realizing the refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption).

[0031] The refrigerant discharged from the exhaust port 16 of the stationary scroll 3 is guided and separated by the guide component 17. The refrigerant is guided by the first guide part 171 to the exhaust pipe 18 to be discharged from the working chamber 7 of the housing 2. The refrigeration oil mixed in the refrigerant is separated from the refrigerant by the second guide part 172 to reduce the oil discharge rate. The refrigeration oil agitated by the balance block 8 is guided by the oil baffle 19 and merged with the refrigeration oil separated from the refrigerant to ensure that the refrigeration oil collection channel is single and to avoid the refrigeration oil flowing freely, which would increase the compressor resistance and increase the compressor internal consumption.

[0032] The upper bracket 6 is welded to the housing 2. Specifically, the upper bracket 6 is fixed to the inner wall of the housing 2 by eight-point welding. The moving scroll 4 and the stationary scroll 3 are mounted opposite each other on the upper side of the upper bracket 6 with a phase angle difference of 180 degrees. The moving scroll 4 is rotatably engaged with the stationary scroll 3. The engagement of the moving scroll 4 and the stationary scroll 3 forms a series of mutually isolated crescent-shaped sealed cavities with continuously changing volumes. The stationary scroll 3 is fixed to the upper bracket 6 by detachable fasteners such as screws. When the compressor is running, the moving scroll 4 rotates in the horizontal direction. The refrigerant that enters the working chamber 7 from the suction pipe 1 is drawn into the crescent-shaped suction cavity formed by the moving scroll 4 and the stationary scroll 3. The refrigerant, after being compressed, is discharged from the exhaust port 16 of the stationary scroll 3. The refrigerant enters the cavity between the housing 2 and the exhaust port 16, and then exits the compressor from the exhaust pipe 18 through the exhaust channel 11.

[0033] Optionally, a cross slip ring 5 is provided at the bottom of the moving scroll 4. The cross slip ring 5 is mounted on the upper bracket 6. Under the anti-rotation restriction of the cross slip ring 5, the moving scroll 4 can perform translational motion with a fixed radius according to the preset center.

[0034] In some embodiments, a drive assembly for driving the moving scroll 4 is provided inside the housing 2. The drive assembly includes a drive member and a transmission member 9 disposed inside the housing 2 and below the upper support 6. One end of the transmission member 9 is connected to the output end of the drive member, and the other end of the transmission member 9 passes through the oil baffle 19, the balance block 8, and the upper support 6 sequentially along the height direction of the housing 2 and is connected to the moving scroll 4. Exemplarily, the drive member includes a motor 10 or other driver in the prior art that can realize the rotation of the transmission member 9. In this application, the drive member is a motor 10. The motor 10 is detachably fixed inside the housing 2 by bolts, and the motor 10 is located below the upper support 6 and spaced apart from the upper support 6 in the height direction of the housing 2. The motor 10 includes a rotor 102 for cooperating with the transmission member 9 and a stator 101 located on the outer periphery of the rotor 102. The stator 101 is fixed to the housing 2 by a heat sleeve.

[0035] Similarly, the transmission component 9 includes a crankshaft or other components that can be connected for transmission. In this application, the transmission component 9 is a crankshaft. One end of the crankshaft is coaxially fixed to the output shaft of the motor 10 through a coupling. The other end of the crankshaft passes through the oil baffle 19, the balance block 8 and the upper bracket 6 in sequence along the height direction of the housing 2, so as to realize the connection between the other end of the crankshaft and the moving scroll 4. Therefore, the rotation of the output shaft of the motor 10 will drive the rotation of the crankshaft, and the crankshaft drives the synchronous rotation of the moving scroll 4.

[0036] In addition, under the anti-rotation restriction of the cross slip ring 5, the moving scroll 4 moves around the center of the crankshaft with a fixed radius, ensuring the reliability of the movement of the moving scroll 4, and ensuring that the moving scroll 4 can maintain mutual meshing with the stationary scroll 3 during rotation.

[0037] Optionally, a sealing ring 20 is provided between the bottom of the balance block 8 and the oil baffle 19, and the sealing ring 20 is provided on the outer periphery of the transmission component 9.

[0038] In some embodiments, a lower support ring 12 is provided inside the housing 2. The lower support ring 12 is located below the motor 10, and the lower support ring 12 and the motor 10 are spaced apart in the height direction of the housing 2. The lower support ring 12 is fixed to the housing 2 by electric welding. A lower bracket 13 is provided on the lower support ring 12, and the lower bracket 13 is fixed to the lower support ring 12 by screws. A thrust plate 15 is provided below the lower bracket 13, and an oil pump 14 is provided at the bottom of the thrust plate 15.

[0039] The housing 2 includes an outer shell 202, an upper cover 201 on the top of the outer shell 202, and a lower cover 203 on the bottom of the outer shell 202. The upper cover 201, the outer shell 202, and the lower cover 203 enclose the housing 2, and an oil working chamber 7 is formed inside it. The suction pipe 1 is connected to the upper cover 201, and the exhaust pipe 18 is connected to the outer shell 202.

[0040] In some embodiments, the diversion channel 23 is connected to the oil inlet 24 through the oil inlet 24. The oil inlet 24 is located at the bottom of the oil baffle 19. By setting the oil inlet 24 of the diversion channel 23 at the bottom of the oil baffle 19, the refrigeration oil located inside the oil baffle 19 can be completely drained out, avoiding the accumulation of refrigeration oil inside the oil baffle 19.

[0041] Optionally, the cross-section of the diversion path 23 perpendicular to its own axis is circular. The diameter of the diversion path 23 is smaller than the minimum distance between the oil baffle 19 and the balance block 8 in a first direction, which is perpendicular to the height direction of the housing 2. The minimum distance between the oil baffle 19 and the balance block 8 in the first direction is ΔD, the diameter of the diversion path 23 is d, the oil inlet chamber 22 is the area between the balance block 8 and the oil baffle 19, and the oil inlet chamber 22 is also the oil stirring area inside the compressor working chamber 7. The oil stirring in the oil stirring area can play a role in oil-gas separation. By limiting the range of the diameter of the diversion path 23, that is, by limiting 0 < d < ΔD, it is possible to avoid the oil inlet 24 of the diversion path 23 being too large, causing the oil to leave the oil stirring area of ​​the balance block 8 too easily. It should be noted that the first direction is... Figure 1 The left and right directions are shown.

[0042] Optionally, the oil baffle 19 includes a vertical wall extending along the height direction of the housing 2 and a horizontal wall extending along the vertical direction of the housing 2. The vertical wall and the horizontal wall are connected to form the oil baffle 19. The oil inlet 24 and the vertical wall are spaced apart in the vertical direction of the housing 2, so as to facilitate the opening of the oil outlet 25 on the oil baffle 19 to ensure the connection strength of the oil baffle 19.

[0043] In some embodiments, the diversion path 23 is connected to the oil guide path 21 through the oil outlet 25, the second guide portion 172 extends along the height direction of the housing 2, and the second guide portion 172 is connected to the first guide portion 171 through a connecting end; in the height direction of the housing 2, the length of the second guide portion 172 is L, and the distance X between the oil outlet 25 and the connecting end satisfies: L / 2 < X < L; by limiting the height of the oil outlet 25 in the second guide portion 172, the oil outlet 25 of the diversion path 23 can be prevented from being set too high, causing the refrigerant oil to flow back to the first guide portion 171, thereby affecting the oil discharge rate of the compressor.

[0044] Optionally, the diversion path 23 includes a first diversion path and a second diversion path that are connected. The first diversion path extends parallel to the height of the housing 2, and the second diversion path extends perpendicular to the height of the housing 2. The first diversion path is used to communicate with the oil inlet chamber 22, and the second diversion path is used to communicate with the oil guide passage 21. That is, the height of the oil inlet 24 is the same as the height of the connection end connecting the first guide portion 171 and the second guide portion 172, and the length of the first diversion path is the same as the height from the oil outlet 25 to the connection end, so as to achieve stable flow of refrigeration oil and prevent the refrigeration oil flowing into the oil guide passage 21 from mixing with the refrigerant in the oil guide passage 21 under the action of inertial force, thereby increasing the oil discharge rate of the compressor.

[0045] In addition, the diversion passage 23 can also be an arc-shaped pipeline structure to divert the refrigeration oil in the oil inlet chamber 22 to the oil guide passage 21.

[0046] In some embodiments, the first drainage portion 171 includes a direct current portion 26 extending along the height direction of the housing 2 and an arc flow portion connected to the direct current portion 26. The end of the arc flow portion away from the direct current portion 26 is connected to the second drainage portion 172. The vent hole of the exhaust pipe 18 is correspondingly provided with the direct current portion 26. The direct current portion 26 is used to guide the refrigerant, while the arc flow portion uses its own curvature to separate the refrigerant from the refrigerant impacting the inner wall surface of the arc flow portion. It should be noted that the arc flow portion is concave towards the inner wall of the housing 2.

[0047] Optionally, the distance between the DC section 26 and the inner wall of the housing 2 is greater than the distance between the upper bracket 6 and the inner wall of the housing 2, so as to ensure that the refrigerant flowing downward from the channel between the upper bracket 6 and the inner wall of the housing 2 can enter the guide member 17 to the maximum extent, so that the refrigerant is separated by oil and gas and discharged from the working chamber 7 through the exhaust pipe 18.

[0048] Similarly, there is a gap between the top of the DC section 26 and the bottom of the upper bracket 6. The gap is designed to facilitate the installation of the current guide 17 inside the housing 2, so as to ensure installation accuracy and avoid interference between the current guide 17 and the upper bracket 6 after installation.

[0049] Optionally, the top of the DC section 26 abuts against the bottom of the upper bracket 6 to prevent the refrigerant from flowing laterally.

[0050] In some embodiments, there is a gap between the bottom of the draining member 17 and the motor 10 in the height direction of the housing 2. Correspondingly, there is a passage extending along the height direction of the housing 2 between the motor 10 and the inner wall surface of the housing 2, so that the refrigeration oil separated from the refrigerant or the refrigeration oil drained from the oil stirring area can flow into the oil pool of the lower cover 203 of the housing 2. At the same time, the refrigeration oil passing through the motor 10 can also cool the motor 10 to ensure the working performance of the motor 10.

[0051] Similarly, the bottom of the draining part 17 can extend into the channel in the height direction of the housing 2 to ensure that the refrigeration oil does not flow into the rotor 102 of the motor 10, which would increase the internal resistance.

[0052] Reference Figures 1-5 In summary, the compressor provided in this application embodiment reduces the mixing of refrigerant and refrigeration oil in the compressor working chamber 7, lowers the oil discharge rate, and also reduces the amount of refrigeration oil flowing back to the lower cover 203 from the gap between the stator 101 and rotor 102 of the motor 10, thus reducing the resistance loss caused by oil churning. Furthermore, the refrigeration oil separated from the refrigerant can be diverted, flowing through the tangential edge of the stator 101 of the motor 10 to the oil sump in the lower cover 203.
