Description

Technical Field

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

[0002] A scroll compressor primarily consists of a housing, a compression mechanism, a support mechanism, a drive mechanism, a working fluid intake pipe, and a working fluid discharge pipe. The compression mechanism consists of an orbiting scroll and a fixed scroll. The drive mechanism includes a stator assembly and a crankshaft rotor assembly. The crankshaft drives the orbiting scroll. An anti-rotation mechanism on the orbiting scroll causes it to rotate in translation relative to the fixed scroll. As the volume of the compression chamber defined by the spiral wraps of the fixed and orbiting scrolls gradually decreases, the refrigerant pressure within the chamber increases. Refrigerant drawn into the compression chamber through the working fluid intake pipe is compressed and eventually discharged through the exhaust port at the center of the scroll. It then exits the compressor through the working fluid discharge pipe and enters the external refrigeration circuit, completing the refrigerant intake, compression, and discharge cycle. Scroll compressors are widely used in air conditioners and heat pumps.

[0003] In scroll compressors, the lubricating effect of lubricating oil significantly impacts their performance. For example, lubricating oil is required in the contact areas between the top and bottom teeth of the rotating and stator plates, the bearing holes of the upper support structure and the crankshaft main bearing, and the contact area between the rotating plate and the upper support structure. Insufficient oil supply can cause wear on the compressor pump assembly, adversely affecting compressor operation. Existing scroll compressor oil supply technologies primarily include gear oil pumps, centrifugal oil supply through oil guide vanes, and differential pressure oil supply. Gear oil pumps generally provide good oil supply at low frequencies, but are less effective at high frequencies. Centrifugal oil supply through oil guide vanes relies on the large centrifugal force to propel the lubricating oil upward, making it more effective at high frequencies but less effective at low frequencies. Differential pressure oil supply requires that the back pressure chamber at the top of the crankshaft be lower than the air pressure in the oil reservoir. A larger pressure differential improves oil supply, making differential pressure oil supply more suitable for high-pressure ratio conditions. To ensure that the air pressure at the top does not mix with the exhaust pressure, it places high demands on the manufacturing process of the contact areas. Since the gear oil pump oil supply and the oil guide plate centrifugal oil supply each have their own advantages and disadvantages, and the two oil supply methods can complement each other, if the two oil supply methods can be effectively combined, sufficient lubricating oil will be provided to the friction pairs of the scroll compressor at any time, so that the compressor can perform better.

[0028] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, a scroll compressor is provided, comprising: a crankshaft 1, an oil pump 2, an oil guide plate oil supply assembly 3 and an upper support structure 4. The crankshaft 1 rotatably passes through the upper support structure 4. The oil pump 2 is arranged at one end of the crankshaft 1 away from the upper support structure 4. An oil supply channel is constructed in the crankshaft 1 that passes through the axial direction of the crankshaft 1. The oil pump 2 is connected to the oil supply channel. During the rotation process, the crankshaft 1 can drive the oil guide plate oil supply assembly 3 to rotate synchronously so that the oil guide plate oil supply assembly 3 can supply oil to the upper support structure 4. In this technical solution, the entire scroll compressor is as follows. Figure 1As shown, the scroll compressor is assembled from a housing 14, an upper cover 15, and a lower cover 16 to form a sealed accommodating chamber. The oil storage area is at the bottom of the accommodating chamber, and the oil pump 2 is in the oil storage area. A compression mechanism is provided on the upper portion of the housing 14. The compression mechanism includes a fixed scroll 17, an orbiting scroll 18, and a cross ring 20. The compression mechanism is mounted on an upper support structure 4, which is fixed to the interior of the housing 14 by welding. The crankshaft 1 rotatably passes through the upper support structure 4 and is connected to the orbiting scroll 18. The oil guide plate oil supply assembly 3 is located on the outside of the crankshaft 1. The rotational speed of the crankshaft 1 represents the operating frequency of the scroll compressor. Generally, when the rotational speed of the crankshaft 1 is less than 110 revolutions per second, it represents low-frequency operation of the compressor, and when the rotational speed of the crankshaft 1 is greater than 110 revolutions per second, it represents high-frequency operation of the compressor. When the crankshaft 1 rotates slowly, i.e., when the compressor is operating at a low frequency, the oil supply from the oil guide plate oil supply assembly 3 is insufficient, but the oil pump 2 can provide sufficient lubricating oil to each friction pair through the oil supply channel within the crankshaft 1. When the crankshaft rotates rapidly, i.e., when the compressor is operating at a high frequency, although the oil supply from the oil pump 2 is moderate, the oil guide plate oil supply assembly 3 can provide sufficient lubricating oil to the upper support structure 4. By effectively combining the oil supply from the gear oil pump and the centrifugal oil supply from the oil guide plate, the compressor can provide sufficient lubricating oil to each friction pair regardless of whether it is operating at high or low speed, thus ensuring lubrication. This overcomes the oil supply defects of using either the gear oil pump or the centrifugal oil supply from the oil guide plate alone, and ensures that the compressor always performs at its best. The upper support structure 4 is most closely connected to the compression mechanism. Only when the upper support structure 4 is adequately supplied with oil can the lubricating oil penetrate into the compression mechanism, thereby lubricating the core components of the scroll compressor. Furthermore, the pressure difference between the upper support structure 4 and the oil storage area is small, making it easier to supply oil from the oil storage area to the upper support structure 4.

[0029] Specifically, the oil guide plate oil supply assembly 3 includes an oil guide plate assembly and an oil supply line 33. The oil guide plate assembly is connected to the upper support structure 4 via the oil supply line 33 and can rotate relative to the oil supply line 33. The crankshaft 1 drives the oil guide plate assembly to rotate via a transmission mechanism. The upper support structure 4 has an oil inlet, and the end of the oil supply line 33 away from the oil guide plate assembly is connected to the oil inlet. When the crankshaft 1 drives the oil guide plate assembly to rotate relative to the oil supply line 33 via the transmission mechanism, the oil guide plate assembly pumps oil upward during rotation and delivers lubricating oil to the upper support structure 4 via the oil supply line 33. Thus, while the oil pump 2 supplies oil, the oil guide plate oil supply assembly 3 also supplies oil synchronously. In addition to this solution, an oil supply channel leading to the upper support structure 4 can also be constructed in the crankshaft 1, and the oil guide plate oil supply assembly 3 can be arranged in the oil supply channel. Then, the crankshaft 1 can drive the oil guide plate oil supply assembly 3 to rotate synchronously during the rotation process, so that the oil guide plate oil supply assembly 3 can supply oil to the upper support structure 4.

[0030] See also Figure 2As shown, the transmission mechanism includes a first gear 5 and a second gear 6. The first gear 5 is mounted on the crankshaft 1, and the second gear 6 is mounted on the oil guide plate assembly. The first gear 5 meshes with the second gear 6. The use of the meshing first gear 5 and the second gear 6 in the transmission mechanism not only achieves efficient transmission but also simplifies the structure of the transmission mechanism.

[0031] Preferably, the diameter of the first gear 5 is larger than the diameter of the second gear 6 , which can amplify the transmission effect and make the oil supply effect of the oil guide plate oil supply assembly 3 better.

[0032] See also Figure 2 and Figure 3 As shown, the oil guide plate assembly includes an oil guide plate 31 and a conduit 32. One end of the oil guide plate 31 is inserted into the conduit 32, and the end of the conduit 32, away from the oil guide plate 31, is rotatably connected to the oil supply line 33. The second gear 6 is sleeved on the conduit 32. When the crankshaft 1 rotates, the crankshaft 1 drives the first gear 5, which in turn drives the second gear 6, which in turn drives the conduit 32. The conduit 32 then drives the oil guide plate 31, ultimately achieving synchronous rotation of the crankshaft 1 and the oil guide plate 31. The portion of the oil guide plate 31 that protrudes from the conduit 32 is located in an oil storage area. The rotating oil guide plate 31 can throw lubricating oil from the oil storage area into the conduit 32, where it enters the oil supply line 33 and ultimately enters the upper support structure 4, enabling the oil guide plate oil supply assembly 3 to supply oil to the friction pair for lubrication.

[0033] In a specific embodiment, a connector is provided at one end of the oil supply line 33 that faces the guide tube 32. The end of the guide tube 32 that faces away from the oil guide plate 31 is rotatably mounted within the connector, and the guide tube 32 is in communication with the oil supply line 33. The connector not only effectively connects the oil supply line 33 and the guide tube 32, but also allows the guide tube 32 to rotate relative to the oil supply line 33.

[0034] Preferably, the connecting piece is a sliding bearing 34 , which can ensure that the conduit 32 can rotate in the connecting piece and can also ensure the sealing of the conduit 32 , the connecting piece and the oil supply pipeline 33 when they are connected.

[0035] See also Figure 3 As shown, the motor stator 7 is also included, and a portion of the oil supply line 33 is wound around the motor stator 7. The motor stator 7 is one of the main heat sources in the compressor, and when lubricating oil flows in the oil supply line 33, the motor stator 7 can be cooled.

[0036] Specifically, a control valve 8 is provided on the oil supply path of the oil supply line 33. The control valve 8 is located between the motor stator 7 and the upper support structure 4. The control valve 8 controls the opening and closing of the oil supply line 33 according to the exhaust gas temperature. When the crankshaft 1 rotates slowly, that is, when the compressor is operating at a low frequency, the temperature of the refrigerant gas discharged from the compression mechanism composed of the fixed scroll 17 and the orbiting scroll 18 is relatively low, and the oil supply from the oil pump 2 can meet the lubrication needs of each friction pair. To prevent excessive lubricating oil from entering the upper support structure 4 through the oil supply line 33 and then entering the compression mechanism from the upper support structure 4, causing serious oil-gas mixing, the control valve 8 can cut off the oil supply line 33. In this way, the lubricating oil transported upward by the oil supply line 33 does not enter the upper support structure 4, and only cools the motor stator 7. When crankshaft 1 rotates rapidly, that is, when the compressor is operating at a high frequency, the temperature of the refrigerant gas discharged from the compression mechanism is high, and the oil pump 2 is insufficiently supplying oil. Control valve 8 can be controlled to clear oil supply line 33. The lubricating oil in oil supply line 33 not only cools motor stator 7 but is also delivered to upper support structure 4 to increase the oil supply and meet lubrication requirements. The rotational speed of crankshaft 1, the operating frequency of the compressor, and the exhaust temperature of the compression mechanism are all interrelated.

[0037] See also Figure 4 and Figure 5 As shown, the control valve 8 includes a valve body 81, which has a first port 11 and a second port 12. The first port 11 and the second port 12 are both located on the oil supply path of the oil supply line 33, with the first port 11 located upstream of the oil supply and the second port 12 located downstream of the oil supply. A thermistor 88 is provided at the second port 12. The thermistor 88 is made of a material with a high thermal expansion coefficient, such as aluminum alloy or copper, and thus has good thermal expansion and contraction properties. When the compressor is running at a low frequency, the temperature of the refrigerant gas discharged from the compression mechanism is relatively low, the thermistor 88 is in a contracted state, and the second port 12 is blocked. The lubricating oil supplied to the oil supply line 33, after cooling the motor stator 7, only flows to the thermistor 88 and does not enter the upper support structure 4, thereby preventing serious oil-gas mixing when the compressor is running at a low frequency. When the compressor operates at high frequency, the temperature of the refrigerant gas discharged from the compression mechanism is relatively high, the thermistor 88 is in an expanded state and connects the second port 12 and the first port 11, and the lubricating oil supplied by the oil supply line 33 enters the upper support structure 4 from the first port 11 through the second port 12, ensuring sufficient oil supply when the compressor operates at high frequency.

[0038] See also Figure 1 and Figure 2As shown, the control valve 8 also includes an oil return pipe 9 and a connecting pipe 10. The upper support structure 4 also has an oil outlet, with the oil return pipe 9 communicating with the oil outlet. The valve body 81 also has a third port 13. The first end of the connecting pipe 10 is connected to the third port 13, and the second end of the connecting pipe 10 is connected to the oil return pipe 9. The control valve 8 also includes an electromagnetic control assembly disposed within the valve body 81. The electromagnetic control assembly is electrically connected to the motor stator 7 and controls whether the third port 13 is connected to the connecting pipe 10 based on the current drawn by the motor stator 7. The oil return pipe 9 leads to an oil storage area. This allows the lubricating oil supplied to the upper support structure 4 to be promptly returned to the oil storage area, thereby enhancing lubricating oil recycling within the compressor. The current drawn by the motor stator 7 when it is energized determines the rotational speed of the crankshaft 1. When the crankshaft 1 rotates slowly, the compressor operates at a low frequency, indicating that the current flowing into the motor stator 7 windings is low. When the crankshaft 1 rotates rapidly, the compressor operates at a high frequency, indicating that the current flowing into the motor stator 7 windings is high. When the current flowing through the windings of the motor stator 7 is low, the electromagnetic control assembly controls the third port 13 to communicate with the connecting pipe 10. When the current flowing through the windings of the motor stator 7 is high, the electromagnetic control assembly controls the third port 13 to disconnect from the connecting pipe 10. This perfectly complements the thermosensitive element 88's control of the oil supply line 33's opening and closing. For example, when the crankshaft 1 rotates slowly and the compressor operates at a low frequency, the temperature of the refrigerant gas discharged from the compression mechanism is low, the current flowing through the windings of the motor stator 7 is low, and the oil pump 2 can supply sufficient oil. To prevent serious oil-gas mixing, when the thermosensitive element 88 contracts and blocks the second port 12, the electromagnetic control assembly controls the third port 13 to communicate with the connecting pipe 10. After cooling the motor stator 7, the lubricating oil supplied to the oil supply line 33 flows from the first port 11 through the third port 13 into the connecting pipe 10, and then returns from the connecting pipe 10 to the bottom oil storage area through the oil return pipe 9. This accelerates the circulation of the lubricating oil while not affecting the lubrication of the friction pairs. At the same time, the circulating lubricating oil has a better cooling effect on the motor stator 7. When the crankshaft 1 rotates faster and the compressor operates at a high frequency, the temperature of the refrigerant gas discharged from the compression mechanism is high, the current flowing through the windings of the motor stator 7 is large, and the oil pump 2 is insufficiently supplied with oil. After the thermistor 88 is in an expanded state and the second port 12 and the first port 11 are connected, the electromagnetic control component controls the third port 13 to be disconnected from the connecting pipe 10. After the lubricating oil cools the motor stator 7, it is also transported to the upper support structure 4 to increase the oil supply to meet lubrication requirements.

[0039] See also Figure 6As shown, the electromagnetic control assembly includes an iron core 82, a baffle 83, and a magnetic conductive component 84. The baffle 83 is used to connect the third port 13 to the connecting pipe 10. The baffle 83 is connected to the iron core 82, and the iron core winding 86 is wound around the iron core 82. The iron core winding 86 is electrically connected to the motor stator 7. The magnetic conductive component 84 is fixed to the inner wall of the valve body 81, and the end of the iron core 82 away from the baffle 83 faces the magnetic conductive component 84. A resistor 87 is provided in the power path of the iron core winding 86 to protect the circuit. When the crankshaft 1 rotates slowly and the compressor operates at a low frequency, the current flowing to the winding of the motor stator 7 is low. Since the iron core winding 86 is energized and connected to the motor stator 7, the current flowing into the iron core winding 86 is also small, so the electromagnetic force generated between the iron core 82 and the magnetic conductive component 84 is small, which is not enough to pull the baffle 83 to block the third port 13, so the third port 13 is connected to the connecting pipe 10; when the crankshaft 1 rotates faster and the compressor runs at a high frequency, it indicates that the current flowing to the winding of the motor stator 7 is large, so the current flowing into the iron core winding 86 is also large, then the electromagnetic force generated between the iron core 82 and the magnetic conductive component 84 is large, and the large electromagnetic force can pull the baffle 83 to block the third port 13, so that the third port 13 is not connected to the connecting pipe 10. Meanwhile, the magnetic conductive component 84 may also be composed of a winding wound on an iron core. When the compressor operates at a low frequency, the magnetic poles of the iron core 82 and the magnetic conductive component 84 are opposite, and the repulsive force prevents the baffle 83 from blocking the third port 13, thereby connecting the third port 13 to the connecting pipe 10. When the compressor operates at a high frequency, the magnetic poles of the iron core 82 and the magnetic conductive component 84 are the same, and the magnetic attraction force causes the baffle 83 to block the third port 13, thereby disconnecting the third port 13 from the connecting pipe 10. The energized connection between the iron core winding 86 and the motor stator 7 enables the motor, crankshaft 1, and control valve 8 to operate synchronously.

[0040] Specifically, an elastic component 85 is connected to the baffle 83. The elastic component 85 and the iron core 82 are arranged on either side of the baffle 83, and the end of the elastic component 85 away from the baffle 83 is connected to the inner wall of the valve body 81. The provision of the elastic component 85 enables the baffle 83 to automatically reset. Furthermore, the elastic component 85 can cooperate with the electromagnetic force generated between the iron core 82 and the magnetic component 84 when the iron core winding 86 is energized. For example, when the current flowing through the iron core winding 86 is low, the electromagnetic force generated between the iron core 82 and the magnetic component 84 is less than the elastic force of the elastic component 85. The baffle 83 is pulled open by the elastic force of the elastic component 85, allowing the third port 13 to communicate with the connecting pipe 10. When the current flowing through the iron core winding 86 is high, the electromagnetic force generated between the iron core 82 and the magnetic component 84 is greater than the elastic force of the elastic component 85. The electromagnetic force causes the baffle 83 to block the third port 13, thus isolating the third port 13 from communicating with the connecting pipe 10.
