Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a compressor and its air conditioner. Background Technology

[0002] In recent years, with the continuous innovation of transportation, the demand for automotive air conditioners has increased significantly. However, the compressors used in current automotive air conditioners are mainly scroll compressors, which are expensive due to the difficulty in machining the moving and stationary disc shapes.

[0003] Currently, due to the high cost of scroll compressors, rolling rotor compressors have a significant cost advantage. Rolling rotor compressors include horizontal and vertical types. For horizontal rolling rotor compressors, the reliability of the lubrication circuit is relatively poor, especially on bumpy roads where the oil level fluctuates greatly, easily leading to poor internal lubrication. Therefore, horizontal rolling rotor compressors are not suitable for use in automotive air conditioners. Existing vertical rolling rotor compressors have higher lubrication circuit reliability, but they require more vertical space for installation, making their application in automotive air conditioners often difficult. Summary of the Invention

[0004] The purpose of this invention is to provide a compressor and its air conditioner, which aims to solve the technical problem that the existing vertical rotary compressors require a large vertical space for installation, making it difficult to apply vertical rotary compressors to automotive air conditioners.

[0005] To address the aforementioned problems, according to one aspect of this application, an embodiment of the present invention provides a compressor, which includes a motor assembly and a pump assembly. The motor assembly includes a stator unit and a rotor unit rotatably disposed within the stator unit. The pump assembly includes a cylinder block component and a crankshaft. The cylinder block component is installed within the rotor unit so that the rotor unit can drive the cylinder block component to rotate around the crankshaft.

[0006] In some implementations, the stator unit, rotor unit, cylinder block components, and crankshaft are all coaxially arranged.

[0007] In some embodiments, the rotor unit has a mounting hole, and the cylinder component is mounted in the mounting hole with an interference fit between the cylinder component and the mounting hole.

[0008] In some embodiments, the cylinder block has a volume chamber and an air inlet communicating with the volume chamber, and an air intake passage is provided in the crankshaft. When the cylinder block rotates around the crankshaft, the air intake passage and the air inlet are always in communication.

[0009] In some embodiments, the stator unit is fixedly mounted on the inner wall of the compressor housing, and a support seat is provided on at least one side of the cylinder block component along the axial direction. The support seat is fixed on the inner wall of the housing, and the crankshaft is inserted on the support seat. The support seat has an air intake passage, one end of which communicates with the outside of the housing. The crankshaft has a first air guide hole that connects the other end of the air intake passage to the air intake channel.

[0010] In some embodiments, the support base has a buffer cavity that connects the other end of the air intake channel to the first air guide hole.

[0011] In some embodiments, the stator unit is fixedly mounted on the inner wall of the compressor housing, and the cylinder component is provided with an exhaust port that connects the volume chamber to the interior of the housing. A valve plate is provided at the exhaust port that opens at a preset pressure value.

[0012] In some embodiments, the crankshaft has an eccentric portion disposed within a volumetric cavity. Rollers that roll in cooperation with the inner wall of the volumetric cavity are fitted onto the eccentric portion. A sliding vane is disposed on the cylinder block component that reciprocates radially along the volumetric cavity. The sliding vane always abuts against the rollers to divide the volumetric cavity into a low-pressure cavity and a high-pressure cavity. An intake port and an exhaust port are disposed on both sides near the sliding vane. The intake port communicates with the low-pressure cavity, and the exhaust port communicates with the high-pressure cavity.

[0013] In some embodiments, the cylinder block component includes a cylinder, a first flange disposed on the first side of the cylinder axis, and a first flange cover fastened to the side of the first flange away from the cylinder. A first flow cavity is provided between the first flange and the first flange cover. The first flow cavity is connected to the air inlet. A crankshaft passes through the first flange and the first flange cover and extends into the first flow cavity. A second air guide hole is provided at the position of the crankshaft in the first flow cavity to connect the air inlet passage with the first flow cavity.

[0014] In some embodiments, the cylinder block component further includes a second flange disposed on the second side of the cylinder axis and a second flange cover fastened to the side of the second flange away from the cylinder. The crankshaft passes through the second flange and the second flange cover. A second flow chamber is provided between the second flange and the second flange cover. The second flow chamber is connected to the exhaust port. A valve plate is disposed in the second flow chamber. The cylinder block component has an exhaust passage that connects the second flow chamber to the internal space of the housing.

[0015] In some embodiments, an oil sump is constructed at the bottom of the housing, and the crankshaft has lubrication lines that deliver lubricating fluid from the oil sump to the volumetric cavity.

[0016] In some embodiments, the lubrication line includes a fluid guide channel formed in the crankshaft and an inlet hole connecting the fluid guide channel to the oil sump, the inlet hole being located near the bottom of the oil sump on the crankshaft.

[0017] In some embodiments, the lubrication line further includes a first outlet hole extending from the inside of the fluid guide channel through the crankshaft, the first outlet hole being located on the crankshaft opposite to the eccentric portion; and / or, the lubrication line further includes a second outlet hole extending from the inside of the fluid guide channel through the crankshaft, the second outlet hole being located on the crankshaft at the junction of the first flange and the cylinder; and / or, the lubrication line further includes a third outlet hole extending from the inside of the fluid guide channel through the crankshaft, the third outlet hole being located on the crankshaft at the junction of the second flange and the cylinder.

[0018] According to another aspect of this application, embodiments of the present invention also provide an air conditioner, which includes a compressor as described above.

[0019] In some implementations, the air conditioner is a vehicle air conditioner.

[0020] Compared with the prior art, the compressor of the present invention has at least the following beneficial effects:

[0021] This invention discloses a compressor, which includes a motor assembly and a pump assembly. The motor assembly includes a stator unit and a rotor unit rotatably disposed within the stator unit. The stator unit is fixed inside the compressor. The pump assembly includes a cylinder block and a crankshaft. The cylinder block is installed within the rotor unit, and the crankshaft is fixed inside the compressor. The rotor unit of the motor assembly rotates, causing the rotor unit to drive the cylinder block to rotate around the crankshaft, thereby compressing the gas. The pump assembly and the motor assembly overlap at least partially in the axial direction, so that the total axial dimension of the motor assembly and the pump assembly in the assembled state is less than the sum of their individual axial dimensions. This significantly reduces the axial dimension of the compressor (i.e., the height dimension in the case of a vertical compressor). At the same time, since the structure or operation of the pump assembly itself is not changed, the reliability of the compressor's lubrication circuit is not affected, making it suitable for the requirements of automotive air conditioners.

[0022] In another aspect, the air conditioner provided by the present invention is manufactured based on the above-mentioned compressor, and its beneficial effects are the same as those of the above-mentioned compressor, which will not be repeated here.

[0044] Example 1

[0045] like Figure 1-6 As shown, an embodiment of the present invention provides a compressor, which includes a motor assembly 1 and a pump assembly 2. The motor assembly 1 includes a stator unit 11 and a rotor unit 12 rotatably disposed within the stator unit 11. The pump assembly 2 includes a cylinder component 21 and a fixedly disposed crankshaft 22. The cylinder component 21 is installed within the rotor unit 12 so that the rotor unit 12 can drive the cylinder component 21 to rotate around the crankshaft 22.

[0046] In this embodiment, the compressor includes a motor assembly 1 and a pump assembly 2. The motor assembly 1 includes a stator unit 11 and a rotor unit 12 rotatably disposed within the stator unit 11. The stator unit 11 is fixed inside the compressor. The pump assembly 2 includes a cylinder component 21 and a fixedly disposed crankshaft 22. Specifically, the crankshaft 22 is inserted into the cylinder component 21 and passes through the cylinder component 21 axially. The cylinder component 21 and the crankshaft 22 can rotate relative to each other. Since the cylinder component 21 is installed inside the rotor unit 12 and the crankshaft 22 is fixedly disposed inside the compressor, that is, the crankshaft 22 is stationary relative to the stator unit 11 of the motor assembly 1. Therefore, after the stator unit 11 of the motor assembly 1 is energized, a magnetic pull is generated. The rotor unit 12 of the motor assembly 1 rotates under the action of the magnetic pull of the stator unit 11, so that the rotor unit 12 can drive the cylinder component 21 to rotate around the crankshaft 22, thereby realizing the compression of gas by the compressor. The gas can be a gaseous refrigerant.

[0047] In this embodiment, the compressor mounts the cylinder assembly 21 within the rotor unit 12. Thus, in the compressor, the pump assembly 2 and the motor assembly 1 at least partially overlap axially. This results in the total axial dimension of the motor assembly 1 and the pump assembly 2 being less than the sum of their individual axial dimensions in the assembled state. Consequently, the axial dimension of the compressor (i.e., the height in the case of a vertical compressor) is significantly reduced. This allows for a reduction in the axial height along the crankshaft 22 of current vertical rotary compressors, thereby reducing the volume of the compressor in this embodiment. Furthermore, since the structure or operation of the pump assembly 2 itself is not altered, the reliability of the compressor's lubrication circuit is not affected.

[0048] In contrast, existing compressors typically arrange the motor assembly 1 and the pump body assembly 2 sequentially along the axial direction, resulting in a total axial dimension occupied by both components in the assembled state that is greater than or equal to the sum of their individual axial dimensions. This leads to a larger axial dimension (e.g., height) of the compressor. Furthermore, as the number of stages in the compressor increases, the height of the compressor also increases significantly; for example, the height of a two-stage compressor is often greater than that of a single-stage compressor.

[0049] The compressor of this invention is a rolling rotor compressor, preferably a vertical rolling rotor compressor. This allows for a reduction in compressor height while maintaining high reliability of the compressor's lubrication circuit, thereby ensuring stable compressor performance and meeting the requirements of automotive air conditioners. Furthermore, the compressor of this invention has the advantage of low cost, facilitating its widespread adoption in automotive air conditioners (especially those for electric vehicles).

[0050] In some embodiments, the stator unit 11, rotor unit 12, cylinder block component 21, and crankshaft 22 are all coaxially arranged.

[0051] In this embodiment, the stator unit 11, rotor unit 12, cylinder block component 21 and crankshaft 22 are all coaxially arranged, which can ensure the smoothness of the stator unit 11 driving the rotor unit 12 to rotate around the crankshaft 22, prevent the compressor from being severely worn due to poor coaxiality, improve the compressor's lifespan, and reduce noise.

[0052] In some embodiments, the rotor unit 12 has a mounting hole, and the cylinder component 21 is mounted in the mounting hole, with the cylinder component 21 and the mounting hole being interference-fitted.

[0053] In this embodiment, the rotor unit 12 has a mounting hole, and the cylinder component 21 is mounted in the mounting hole. Specifically, the mounting hole of the rotor unit 12 is coaxially arranged with the rotation axis of the rotor unit 12. In the axial direction of the cylinder component 21, the cylinder component 21 can be completely located in the mounting hole, or the cylinder component 21 can be completely located in the mounting hole. The cylinder component 21 is interference-fitted with the mounting hole, which can securely mount the cylinder component 21 in the mounting hole of the rotor unit 12, preventing the cylinder component 21 from falling off the rotor unit 12 when the rotor unit 12 rotates at high speed. Of course, other methods such as bonding and welding can also be used to fix the cylinder component 21 in the mounting hole of the rotor unit 12.

[0054] In some embodiments, the cylinder block component 21 has a volume chamber 211 and an air inlet communicating with the volume chamber 211, and the crankshaft 22 has an air intake channel 221. When the cylinder block component 21 rotates around the crankshaft 22, the air intake channel 221 is always connected to the air intake.

[0055] In this embodiment, the cylinder block component 21 has a volume chamber 211 and an air inlet communicating with the volume chamber 211. The crankshaft 22 has an air intake channel 221, which is specifically a refrigerant flow path into the volume chamber 211. The air intake channel 221 can extend axially along the crankshaft 22, and the crankshaft 22 can extend upwards to form a compressor. The air intake channel 221 can extend to the top end face of the crankshaft 22, allowing air to enter from the top end face of the crankshaft 22. This allows the gaseous refrigerant to be compressed, or a gas-liquid mixture of refrigerant, to pass through the air intake of the crankshaft 22. The air inlet and the air passage 221 are introduced into the volume chamber 211 inside the cylinder component 21. The air is compressed through the volume chamber 211, thereby achieving the compression of gas by the compressor. When the cylinder component 21 rotates around the crankshaft 22, the air inlet and the air passage 221 are always connected, which can ensure that the rotor unit 12 of the motor assembly 1 rotates under the magnetic pull of the stator unit 11. During the process of the rotor unit 12 driving the cylinder component 21 to rotate around the crankshaft 22, the volume chamber 211 can always draw in air, ensuring the smooth airflow path of the compressor.

[0056] In some embodiments, the stator unit 11 is fixedly disposed on the inner wall of the compressor housing 3, and a support seat 4 is provided on at least one side of the cylinder block component 21 along the axial direction. The support seat 4 is fixed on the inner wall of the housing 3, and the crankshaft 22 is inserted into the support seat 4. The support seat 4 has an air intake passage 41, one end of which communicates with the outside of the housing 3. The crankshaft 22 has a first air guide hole 223 that communicates the other end of the air intake passage 41 with the air intake channel 221.

[0057] In this embodiment, the stator unit 11 is specifically fixedly mounted on the inner wall of the compressor housing 3. A support 4 is provided on at least one side of the cylinder component 21 along its axial direction. The support 4 can be located on either side of the cylinder component 21 along its axial direction, or it can be provided on both sides of the cylinder component 21 along its axial direction. Figure 1 , Figure 4 and Figure 6The diagram shows a support 4 on one axial side of the cylinder block component 21, with the support 4 positioned above the cylinder block component 21. In this case, the end of the crankshaft 22 located below the cylinder block component 21 can be fixed to the bottom of the compressor housing 3. The support 4 is fixed to the inner wall of the housing 3, and the crankshaft 22 is inserted into the support 4. The support 4 fixes the crankshaft 22 in this embodiment. In this embodiment, the intake air passage 41 does not extend upwards to the top end of the crankshaft 22. The intake air passage 41 is provided on the support 4. One end of the intake air passage 41 is connected to the outside of the housing 3. An intake pipe 6 extending into the housing 3 can be inserted into the intake air passage 41 to facilitate connection with the air conditioning system piping. The crankshaft 22 has a first air guide hole 223 that connects the other end of the intake air passage 41 to the intake channel 221. The first air guide hole 223 can penetrate the crankshaft 22 outward from inside the intake channel 221 along the direction of the crankshaft 22. The low-pressure chamber of the compressor is connected to the air conditioning system through the intake air passage 41, the intake channel 221, and the first air guide hole 223.

[0058] The compressor housing 3 may include a cylinder 32, an upper cover 33 disposed on the upper end of the cylinder 32, and a lower cover 34 disposed on the upper end of the cylinder 32, which together form the compressor housing 3.

[0059] In some embodiments, the support base 4 has a buffer cavity 42 that connects the other end of the air intake channel 41 to the first air guide hole 223.

[0060] In this embodiment, the support base 4 has a buffer chamber 42 that connects the other end of the intake air passage 41 to the first air guide hole 223. The buffer chamber 42 can reduce the pressure and buffer the refrigerant flow, making the refrigerant flow path in the intake passage 221 of the crankshaft 22 smoother after passing through the buffer chamber 42. The intake air passage 41 on the support base 4 is used to cooperate with the suction pipe 6 so that the refrigerant from the system can enter the low-pressure chamber (suction volume chamber) and then participate in the internal circulation of the compressor.

[0061] The support base 4 may specifically include a support plate 43 and a cover plate 44, which are interlocked. An air inlet channel 41 is opened on the support plate 43, and a buffer cavity 42 can be opened on the side of the support plate 43 facing the cover plate 44. This structure can facilitate the processing of the buffer cavity 42 and reduce the processing difficulty.

[0062] In some embodiments, the stator unit 11 is fixedly disposed on the inner wall of the compressor housing 3, the cylinder component 21 is provided with an exhaust port that connects the volume chamber 211 with the interior of the housing 3, and a valve plate that opens at a preset pressure value is provided at the exhaust port.

[0063] In this embodiment, an exhaust port is provided on the cylinder component 21 to connect the volume chamber 211 with the interior of the housing 3, and a valve plate is provided at the exhaust port to open at a preset pressure value. The preset pressure value is a set exhaust pressure value. When the gas in the volume chamber 211 is compressed to the exhaust pressure value, the valve plate is opened to discharge the high-pressure gas in the volume chamber 211 into the interior of the housing 3.

[0064] In some embodiments, the crankshaft 22 has an eccentric portion 222 disposed within the volume cavity 211. A roller 23 is fitted onto the eccentric portion 222 and rolls against the inner wall of the volume cavity 211. A sliding vane is disposed on the cylinder block component 21 and reciprocates radially along the volume cavity 211. The sliding vane always abuts against the roller 23 to divide the volume cavity 211 into a low-pressure chamber and a high-pressure chamber. The air inlet and exhaust outlet are disposed on opposite sides near the sliding vane. The air inlet communicates with the low-pressure chamber, and the exhaust outlet communicates with the high-pressure chamber.

[0065] In this embodiment, the crankshaft 22 has an eccentric portion 222, which is disposed within the volume cavity 211. A roller 23 is fitted onto the eccentric portion 222, rollingly engaging with the inner wall of the volume cavity 211. This rolling engagement between the roller 23 on the eccentric portion 222 and the inner wall of the volume cavity 211 reduces wear between the eccentric portion 222 and the inner wall of the volume cavity 211, preventing excessive wear that could lead to poor compression efficiency and reduced compressor life. The cylinder block component 21 is provided with a sliding vane that reciprocates radially along the volume cavity 211. The vane always abuts against the roller 23, dividing the volume cavity 211 into a low-pressure chamber and a high-pressure chamber. Specifically, the cylinder block component 21 may have a sliding vane that reciprocates radially along the volume cavity 211. An extended sliding vane groove houses the sliding vane. A spring or other elastic element is positioned between the end of the sliding vane furthest from the roller 23 and the cylinder component 21 to ensure the sliding vane always abuts against the roller 23. Alternatively, the high-pressure chamber can be connected to the sliding vane groove at the end of the sliding vane furthest from the roller 23, using high-pressure gas within the high-pressure chamber to maintain constant contact between the sliding vane and the roller 23. The sliding vane has an R-surface that abuts against the outer circumference of the roller 23, reducing wear. The air inlet and exhaust port are located on opposite sides near the sliding vane. The air inlet connects to the low-pressure chamber, which is specifically an intake chamber, enabling the intake process. The exhaust port connects to the high-pressure chamber, which is a compression chamber for compressing gas. After compression, the high-pressure gas is discharged through the exhaust port.

[0066] In some embodiments, the cylinder component 21 includes a cylinder 212, a first flange 213 disposed on the first axial side of the cylinder 212, and a first flange cover 214 fastened to the side of the first flange 213 away from the cylinder 212. A first flow cavity 2131 is provided between the first flange 213 and the first flange cover 214. The first flow cavity 2131 is connected to the air inlet. The crankshaft 22 passes through the first flange 213 and the first flange cover 214 and extends into the first flow cavity 2131. A second air guide hole 224 is provided at the position of the crankshaft 22 within the first flow cavity 2131 to connect the air intake channel 221 with the first flow cavity 2131.

[0067] In this embodiment, the cylinder component 21 includes a cylinder 212, a first flange 213 disposed on the first axial side of the cylinder 212, and a first flange cover 214 fastened to the side of the first flange 213 away from the cylinder 212. A first flow cavity 2131 is provided between the first flange 213 and the first flange cover 214. Specifically, the first flow cavity 2131 is opened on the side of the first flange 213 facing the first flange cover 214. The first flange 213 and the first flange cover 214 fasten together to form a sealed space. This structure facilitates the machining of the first flow cavity 2131. The first flow cavity 2131 is connected to the air inlet. The crankshaft 22 passes through the first flange 213 and the first flange cover 214. The crankshaft 22 extends into the first flow cavity 2131. A second air guide hole 224 is provided at the position of the crankshaft 22 within the first flow cavity 2131, which connects the intake channel 221 with the first flow cavity 2131. The second air guide hole 224 can penetrate the crankshaft 22 radially outward from the intake channel 221, allowing the portion of the crankshaft 22 extending into the first flow cavity 2131 to be suspended within the first flow cavity 2131. When the cylinder 212, the first flange 213, and the first flange 213 of the cylinder block component 21 rotate around the crankshaft 22, the second air guide hole 224 is always connected to the intake port through the first flow cavity 2131, so that the low-pressure chamber (intake volume chamber) can always draw in air, ensuring the smooth flow path of the compressor intake.

[0068] In some embodiments, the cylinder block component 21 further includes a second flange 215 disposed on the second axial side of the cylinder 212 and a second flange cover 216 fastened to the side of the second flange 215 away from the cylinder 212. The crankshaft 22 passes through the second flange 215 and the second flange cover 216. A second flow cavity 2151 is provided between the second flange 215 and the second flange cover 216. The second flow cavity 2151 is connected to the exhaust port. The cylinder block component 21 has an exhaust channel 24 that connects the second flow cavity 2151 to the internal space of the housing 3. An exhaust pipe 5 is inserted into the housing 3.

[0069] In this embodiment, a second flange 215 is provided on the second axial side of the cylinder 212, and a second flange cover 216 is fastened to the side of the second flange 215 away from the cylinder 212. A volume cavity 211 is formed by the first flange 213 and the second flange 215 located on both axial sides of the cylinder 212. The crankshaft 22 passes through the second flange 215 and the second flange cover 216. A second flow cavity 2151 is provided between the second flange 215 and the second flange cover 216, and the second flow cavity 2151 communicates with the exhaust port. The valve plate is disposed within the second flow cavity 2151. Specifically, the second flow cavity 2151 is formed within the second flange. The side of 215 facing the second flange cover 216 facilitates the second flow chamber 2151. The second flange 215 and the second flange cover 216 are fastened together to form a sealed space. This structure facilitates the processing of the second flow chamber 2151 and the installation of the valve plate. The cylinder component 21 has an exhaust channel 24 that connects the second flow chamber 2151 with the internal space of the housing 3. An exhaust pipe 5 is inserted on the housing 3. When the gas in the high-pressure chamber is compressed to the exhaust pressure value, the valve plate is opened. At this time, the gas is discharged into the housing 3 of the compressor through the exhaust port, the second flow chamber 2151 and the exhaust channel 24, and then the gas is guided to the circulation system of the air conditioner through the exhaust pipe 5.

[0070] like Figure 1 , Figure 4 and Figure 6 As shown in the diagram, the exhaust passage 24 extends upward from the second flow chamber 2151 through the second flange 215, cylinder 212, first flange 213, and first flange cover 214, discharging gas to the top of the first flange cover 214. Since the support base 4 is located above the cylinder body component 21 and the exhaust pipe 5 is located above the support base 4, a through hole can be provided on the support base 4 to allow the airflow to smoothly enter the exhaust pipe 5, ensuring the smooth flow path of the airflow.

[0071] In some embodiments, the bottom of the housing 3 is provided with an oil sump 31, and the crankshaft 22 has a lubrication pipeline for conveying the lubricating fluid in the oil sump 31 to the volumetric cavity 211.

[0072] In this embodiment, an oil sump 31 can be constructed at the bottom of the housing 3, and a lubrication pipeline can be provided on the crankshaft 22. The lubrication pipeline transports the lubricating fluid in the oil sump 31 to the volume chamber 211. Various components in the volume chamber 211 can be lubricated through the lubrication pipeline on the crankshaft 22, thereby reducing compressor wear and improving compressor life.

[0073] In some embodiments, the lubrication line includes a fluid guide channel 225 formed in the crankshaft 22 and an inlet hole 226 connecting the fluid guide channel 225 to the oil sump 31, the inlet hole 226 being formed in the crankshaft 22 near the bottom of the oil sump 31.

The fluid inlet 226 is opened on the crankshaft 22 near the bottom of the oil sump 31 to prevent the lubricant level in the oil sump 31 from being too low, which would prevent the lubrication pipeline from being able to smoothly supply fluid.

[0075] In some embodiments, the lubrication line further includes a first outlet hole 227 extending from the inside of the fluid guide channel 225 through the crankshaft 22, the first outlet hole 227 being located on the crankshaft 22 at a position opposite to the eccentric portion 222.

The first outlet hole 227 is opened on the crankshaft 22 at a position opposite to the eccentric portion 222. By setting the first outlet hole 227 on the crankshaft 22 opposite to the eccentric portion 222, the lubricating fluid in the oil sump 31 can be guided to the gap between the eccentric portion 222 and the roller 23 through the inlet hole 226, the fluid guide channel 225 and the first outlet hole 227 to lubricate the inner hole of the roller 23 and the eccentric portion 222.

[0077] In some embodiments, the lubrication line further includes a second outlet hole 228 extending from the inside of the fluid guide channel 225 through the crankshaft 22, the second outlet hole 228 being located on the crankshaft 22 at the junction of the first flange 213 and the cylinder 212.

[0078] In this embodiment, the lubrication pipeline further includes a second outlet hole 228 that extends from the inside of the fluid guide channel 225 through the crankshaft 22. The second outlet hole 228 can extend from the inside of the fluid guide channel 225 through the crankshaft 22 in the radial direction of the crankshaft 22. The second outlet hole 228 is located on the crankshaft 22 at the junction of the first flange 213 and the cylinder 212. The lubricating fluid in the oil sump 31 can be guided to the cylinder 212 through the inlet hole 226, the fluid guide channel 225 and the second outlet hole 228, so as to lubricate the contact parts between the first flange 213 and the eccentric part 222 and between the first flange 213 and the roller 23.

[0079] In some embodiments, the lubrication line further includes a third outlet hole 229 extending from the inside of the fluid guide channel 225 through the crankshaft 22. The third outlet hole 229 is located on the crankshaft 22 at the junction of the second flange 215 and the cylinder 212.

[0080] In this embodiment, the lubrication pipeline further includes a third outlet hole 229 extending from the inside of the fluid guide channel 225 through the crankshaft 22. The third outlet hole 229 can extend from the inside of the fluid guide channel 225 through the crankshaft 22 in the radial direction of the crankshaft 22. The third outlet hole 229 is located on the crankshaft 22 at the junction of the second flange 215 and the cylinder 212. The lubricating fluid in the oil sump 31 can be guided to the cylinder 212 through the inlet hole 226, the fluid guide channel 225 and the third outlet hole 229, so as to lubricate the contact parts between the second flange 215 and the eccentric part 222 and between the second flange 215 and the roller 23.

[0081] Example 2

[0082] This invention also provides an air conditioner, which includes the compressor of Embodiment 1.

[0083] In this embodiment, as Figure 6 As shown, the air conditioner may specifically include the compressor of Embodiment 1, as well as the condenser 7, the throttle valve 8, and the evaporator 9. The condenser 7, the throttle valve 8, and the evaporator 9 are connected by pipes. The evaporator 9 is connected to the suction pipe 6 of the compressor, and the condenser 7 is connected to the discharge pipe 5 of the compressor, forming a closed-loop refrigerant flow path for the air conditioner.

[0084] In some implementations, the air conditioner is a vehicle air conditioner.

[0085] The compressor in this embodiment is a rolling rotor compressor, and preferably a vertical rolling rotor compressor. This allows for a reduction in compressor height while ensuring high reliability of the compressor's lubrication circuit, thereby ensuring stable compressor performance and meeting the requirements of automotive air conditioners.

[0086] The present invention reduces the height of the compressor by surrounding the rotor unit 12 with the pump body assembly 2 and the stator unit 11 with the rotor unit 12, thereby ensuring better compressor reliability while meeting the space limitations of vehicle air conditioning. In this design, the crankshaft 22 does not rotate during compressor operation; instead, the rotor rotates, driving the cylinder block assembly 21 to rotate, thus achieving gas compression.

[0087] As can be seen, by surrounding the rotor unit 12 with the pump body assembly 2, the compressor of the present invention can reduce the height of the compressor, thereby ensuring the reliability of the compressor while meeting the space constraints of the vehicle air conditioning system. The compressor of the present invention can both ensure the reliable operation of the compressor and meet the space constraints of the vehicle air conditioning system, thus better ensuring the reliability of the vehicle air conditioner.

[0088] In summary, it is readily understood by those skilled in the art that, without conflict, the aforementioned advantageous technical features can be freely combined and superimposed.

[0089] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

[0090] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
