[0046] Hereinafter, a compressor 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] like Figure 1-3 As shown, the compressor 100 according to an embodiment of the present invention includes: a shell assembly 1 and a plurality of compression assemblies 2, the shell assembly 1 includes an installation cavity 14, an intake cavity 111, an exhaust cavity 112 and an oil storage cavity 121, the exhaust cavity 112 is connected to the oil storage cavity 121, and the oil storage cavity 121 is connected to the intake cavity 111; the compression assembly 2 is arranged in the installation cavity 14, the compression assembly 2 is provided with an exhaust channel 221 and an intake channel, the intake channel of the compression assembly 2 is connected to the intake cavity 111, and the exhaust channel 221 is connected to the exhaust cavity 112.

[0048] As a result, the lubricating oil can fully and effectively lubricate the compression component 2 along with the refrigerant, which is beneficial to improving the movement smoothness of the compression component 2 and improving the reliability of the compressor 100.

[0049] First, if Figure 1 As shown, the compressor 100 includes a housing assembly 1 and a compression assembly 2. The housing assembly 1 defines a mounting cavity 14 in which the compression assembly 2 is mounted, and the housing assembly 1 further defines an assembly cavity 17 in which the motor assembly 7 is mounted.

[0050] The housing assembly 1 is provided with an air intake chamber 111 and an air discharge chamber 112, the air discharge chamber 112 is connected to an oil storage chamber 121, the air intake chamber 111 is provided with an air intake port, the air intake port is connected to the outside of the compressor 100, so that the external refrigerant can flow into the air intake chamber 111 through the air intake port. The housing assembly 1 is also provided with an oil storage chamber 121, the oil storage chamber 121 is used to store lubricating oil, the air discharge chamber 112 is connected to the oil storage chamber 121, and the oil storage chamber 121 is connected to the air intake chamber 111, and the lubricating oil in the oil storage chamber 121 can flow into the air intake chamber 111.

[0051] The compression assembly 2 is arranged in the installation cavity 14, and the compression assembly 2 includes a first scroll 21 and a second scroll 22, and the first scroll 21 and the second scroll 22 can be movably matched, and the motor assembly 7 is used to drive the first scroll 21 to move relative to the second scroll 22, so that the compression assembly 2 can suck in the refrigerant and compress it. Each compression assembly 2 is provided with an exhaust channel 221 and an air intake channel (not shown in the figure), the air intake channel is used to communicate with the air intake chamber 111, and the exhaust channel 221 is used to communicate with the exhaust chamber 112. It should be noted that the first scroll 21 can be a movable scroll, and the second scroll 22 can be a fixed scroll.

[0052] In the specific working process, as the compression assembly 2 operates, the refrigerant located outside the compressor 100 can flow into the suction chamber 111 through the suction port, and the lubricating oil in the oil storage chamber 121 can flow into the suction chamber 111, and the lubricating oil and the refrigerant are mixed in the suction chamber 111; then, the refrigerant carrying the lubricating oil can flow into the compression assembly 2 through the corresponding suction channels and be compressed, and the compressed refrigerant can flow into the exhaust chamber 112 from the exhaust channel 221, and flow through the exhaust chamber 112 to flow into the oil storage chamber 121, and the lubricating oil is separated and collected in the oil storage chamber 121, and the refrigerant can be discharged to the outside of the compressor 100. It can be understood that during the circulation process, the lubricating oil can fully and effectively lubricate the compression assembly 2, thereby improving the movement stability of the compression assembly 2.

[0053] According to the compressor 100 of the embodiment of the present invention, the oil storage chamber 121 is connected with the suction chamber 111, so that the lubricating oil can flow into the suction chamber 111 to mix with the refrigerant, so that the lubricating oil can fully and effectively lubricate the compression component 2 along with the refrigerant, which is beneficial to improve the movement smoothness of the compression component 2 and improve the reliability of the compressor 100.

[0054] In some embodiments of the present invention, reference Figure 1 As shown, the suction channel can be arranged to communicate with the installation cavity 14, and the suction cavity 111 can be arranged to communicate with the installation cavity 14. That is, as the compression assembly 2 operates, the refrigerant can first flow into the installation cavity 14, and then flow through the corresponding suction channels to flow into the multiple compression assemblies 2 respectively, thereby being compressed.

[0055] Through the above arrangement, it is not necessary to provide a flow guide structure between the main housing 11 and the compression assembly 2, which is beneficial to simplifying the structure of the compressor 100 and improving the practicality of the compressor 100.

[0056] In some embodiments of the present invention, Figure 1 As shown, the compression assembly 2 further includes an exhaust end cover 23, which is disposed on a side of the second scroll 22 away from the first scroll 21, and a connecting passage 231 is disposed in the exhaust end cover 23, and the second scroll 22 is provided with an exhaust passage 221, and the exhaust passage 221 can be connected to the exhaust chamber 112 through the connecting passage 231. Thus, the layout difficulty of the compressor 100 can be reduced.

[0057] In some embodiments of the present invention, Figure 1 As shown, a communication groove 232 is provided on one side of the exhaust end cover 23 facing the second scroll 22, and the communication groove 232 is communicated with the communication channel 231. The second scroll 22 is provided with a plurality of exhaust channels 221, and the plurality of exhaust channels 221 are arranged at intervals along the circumference of the second scroll 22, and the plurality of exhaust channels 221 are all communicated with the communication groove 232. Thus, the exhaust efficiency of the compression assembly 2 can be improved.

[0058] In some embodiments of the present invention, Figure 1 As shown, there are multiple compression components 2, and multiple compression components 2 can work simultaneously, thereby improving the compression efficiency of the refrigerant.

[0059] In some embodiments of the present invention, Figure 1 As shown, multiple compression assemblies 2 may be connected in parallel, so that multiple compression assemblies 2 can compress the refrigerant at the same time, which is beneficial to improving the working efficiency of the compressor 100.

[0060] In some embodiments of the present invention, Figure 1 As shown, multiple compression assemblies 2 can be coaxially arranged. Thus, space can be saved, and multiple compression assemblies 2 can be driven by the same driving structure (i.e., the crankshaft 3 described below), which is conducive to reducing the structural complexity of the compressor 100.

[0061] In some embodiments of the present invention, the housing assembly 1 is provided with at least one flow passage 15, the flow passage 15 connects the suction chamber 111 and the air inlet of the compression assembly 2 corresponding to the flow passage 15, and the refrigerant in the suction chamber 111 can flow to the air inlet of the corresponding compression assembly 2 through the flow passage 15, so as to ensure that each compression assembly 2 can inhale enough refrigerant. Thus, the reliability of the compressor 100 is improved.

[0062] In some embodiments of the present invention, the housing assembly 1 includes a partition 18, the installation cavity 14 and the suction cavity 111 are located on both sides of the partition 18, and the partition 18 is provided with at least one flow passage 15. Through the above arrangement, the relative independence between the installation cavity 14 and the suction cavity 111 can be improved, which is conducive to improving the reliability of the compressor 100.

[0063] In some embodiments of the present invention, Figure 1 As shown, the air suction cavity 111 is provided with a plurality of flow passages 15, and the flow passages 15 are used to communicate with the mounting cavity 14. The compression components 2 are provided in plurality, such as two, three or more, and the plurality of compression components 2 are arranged in the mounting cavity 14 at intervals along the axial direction, and each compression component 2 is provided corresponding to at least one flow passage 15, such as one, two or even more. Exemplarily, the compression components 2 can be provided in three, and the air suction cavity 111 is provided with three flow passages 15, and the three flow passages 15 are provided in a one-to-one correspondence with the three compression components 2.

[0064] It is understandable that the refrigerant in the suction chamber 111 can flow to the corresponding compression assembly 2 through the flow channel 15 to ensure that each compression assembly can inhale sufficient refrigerant, which is beneficial to improving the reliability of the compressor 100.

[0065] In some embodiments of the present invention, the exhaust chamber 112 and the oil storage chamber 121 are independent chambers spaced apart in the housing assembly 1 , and the oil storage chamber 121 is provided with an oil-gas separation component 16 for the refrigerant discharged from the exhaust chamber 112 .

[0066] For example, Figure 1 As shown, the exhaust chamber 112 can be provided in the main housing 11, and the oil storage chamber 121 can be provided in the high-pressure housing 12, so that the exhaust chamber 112 and the oil storage chamber 121 are constructed as relatively independent chambers, so as to extend the flow path of the refrigerant and reduce the flow rate of the refrigerant. At the same time, an oil-gas separator 16 can be provided in the oil storage chamber 121, and the oil-gas separator 16 is used to separate the refrigerant discharged from the exhaust chamber 112, so as to separate the refrigerant and the lubricating oil, and the separated lubricating oil can fall into the oil storage chamber 121 for storage, and the separated refrigerant can be discharged to the outside of the compressor 100.

[0067] It is understandable that by constructing the exhaust chamber 112 and the oil storage chamber 121 as independent chambers, the processing difficulty can be reduced, and the flow rate of the refrigerant into the oil storage chamber 121 can be slowed down to improve the separation effect of the lubricating oil.

[0068] In some embodiments of the present invention, Figure 1 As shown, the connecting port 113 between the exhaust chamber 112 and the oil storage chamber 121 can be arranged at the top of the oil storage chamber 121, and the oil-gas separator 16 can be correspondingly arranged at the top of the oil storage chamber 121, so that the oil-gas separator 16 can be arranged opposite to the connecting port 113, so that the oil-gas separator 16 can separate the refrigerant blown out of the connecting port 113.

[0069] Through the above-mentioned arrangement, the space in the oil storage chamber 121 can be fully utilized, ensuring that the oil-gas separator 16 maintains a certain distance from the lubricating oil stored in the oil storage chamber 121 to prevent the lower end of the oil-gas separator 16 from extending into the lubricating oil and causing the refrigerant to be unable to be discharged, thereby improving the reliability of the compressor 100.

[0070] In some embodiments of the present invention, Figure 1 As shown, the compressor 100 is constructed as a horizontal compressor, and the suction chamber 111 can be arranged at the bottom of the shell component 1, and the exhaust chamber 112 can be arranged at the top of the shell component 1. In the specific working process, as the compression component 2 is running, the refrigerant located outside the compressor 100 can flow into the suction chamber 111 through the suction port, and the lubricating oil in the oil storage chamber 121 can flow into the suction chamber 111, and the lubricating oil is mixed with the refrigerant in the suction chamber 111; then, the refrigerant carrying the lubricating oil can flow upward into the compression component 2 through the corresponding suction channel and be compressed, and the compressed refrigerant can flow upward into the exhaust chamber 112 through the exhaust channel 221, and flow through the exhaust chamber 112 to flow into the oil storage chamber 121.

[0071] Through the above arrangement, in the process of the refrigerant flowing from the suction chamber 111 into the exhaust chamber 112, the flow rate of the refrigerant can be gradually reduced so that the lubricating oil can remain in the installation chamber 14 and the oil storage chamber 121 as much as possible, which is beneficial to improving the lubrication effect.

[0072] In some embodiments of the present invention, Figure 1 As shown, the compressor 100 includes a crankshaft 3, which is connected to the motor assembly 7, and the crankshaft 3 is axially arranged in the first scroll 21. When the motor assembly 7 drives the crankshaft 3 to rotate, the crankshaft 3 is used to drive the first scroll 21 of the compression assembly 2 to move, thereby compressing the refrigerant. In the radial direction of the crankshaft 3, the suction chamber 111 is arranged opposite to the installation chamber 14, and the exhaust chamber 112 is arranged opposite to the installation chamber 14.

[0073] Through the above arrangement, the flow path of the refrigerant can be shortened, the difficulty of processing the shell assembly 1 is reduced, and the overall practicality of the compressor 100 is improved.

[0074] In some embodiments of the present invention, the compression assembly 2 includes a first scroll 21; the compressor 100 also includes a crankshaft 3 and a bearing support 4, the crankshaft 3 is respectively passed through multiple first scrolls 21 to drive the multiple first scrolls 21 to move; the bearing support 4 is arranged in the housing assembly 1 to support the crankshaft 3, and a support bearing 5 is arranged between the bearing support 4 and the crankshaft 3; the crankshaft 3 is provided with a first oil return channel 31 connected to the oil storage chamber 121, and the first oil return channel 31 is used to lubricate the support bearing 5.

[0075] For example, refer to Figure 1-Figure 3 As shown, the compression assembly 2 includes a first scroll 21 and a second scroll 22, and the first scroll 21 and the second scroll 22 can be movably matched. When the first scroll 21 moves relative to the second scroll 22, the compression assembly 2 can suck in the refrigerant for compression. The compressor 100 also includes a crankshaft 3, and the motor assembly 7 is connected to the crankshaft 3. The crankshaft 3 is axially penetrated by multiple first scrolls 21. When the motor assembly 7 drives the crankshaft 3 to rotate, the crankshaft 3 can drive the multiple first scrolls 21 to move synchronously, so that the multiple compression assemblies 2 can compress the refrigerant at the same time.

[0076] The compressor 100 also includes a bearing support 4, which is arranged in the shell assembly 1. The bearing support 4 is located on the side of the multiple compression components 2 away from the high-pressure shell 12. The crankshaft 3 is axially inserted into the bearing support 4, and a support bearing 5 is provided between the bearing support 4 and the crankshaft 3. The support bearing 5 is used to rotatably support the crankshaft 3 on the bearing support 4 so that the crankshaft 3 can rotate relative to the bearing support 4.

[0077] Among them, a first oil return channel 31 may be provided in the crankshaft 3, one end of the first oil return channel 31 is communicated with the oil storage chamber 121, and the first oil return channel 31 is provided with an oil outlet opposite to the support bearing 5, and the lubricating oil in the oil storage chamber 121 may flow into the first oil return channel 31 and flow from the oil outlet to the support bearing 5 to lubricate the support bearing 5. Thus, the movement smoothness of the crankshaft 3 can be improved, and the reliability of the compressor 100 can be improved.

[0078] In some embodiments of the present invention, Figure 1As shown, a lubrication chamber 6 can be defined between the bearing bracket 4 and the support bearing 5, and the lubrication chamber 6 is connected to the first oil return channel 31, and the lubricating oil in the first oil return channel 31 can flow into the lubrication chamber 6 to continuously lubricate the support bearing 5. It should be noted that the lubrication chamber 6 is connected to the mounting chamber 14, and the lubricating oil in the lubrication chamber 6 can flow into the mounting chamber 14 and flow into the compression assembly 2 along with the refrigerant in the mounting chamber 14. In this way, the lubrication effect of the lubricating oil on the support bearing 5 can be improved.

[0079] In some embodiments of the present invention, the bearing support 4 includes a first bearing support 41, the crankshaft 3 axially penetrates the first bearing support 41, the first oil return channel 31 includes a connected axial flow path 311 and a radial flow path 312, the axial flow path 311 is connected to the oil storage chamber 121, and a first oil outlet 32 ​​is formed at the radial outer end of the radial flow path 312, and the first oil outlet 32 ​​is connected to the lubrication chamber 6.

[0080] For example, refer to Figure 1 and Figure 2 As shown, the bearing support 4 includes a first bearing support 41, which is integrally formed with the rear main housing 11b and is located on the side of the multiple compression components 2 away from the high-pressure housing 12, and the crankshaft 3 is located in the assembly cavity 17. One end of the crankshaft 3 can axially penetrate the first bearing support 41 and be sequentially penetrated in the multiple first scrolls 21. The first bearing support 41 is installed with a support bearing 5, which is used to support the crankshaft 3, and a lubrication cavity 6 is formed between the first bearing support 41 and the support bearing 5.

[0081] The first oil return passage 31 includes an axial flow path 311 and a radial flow path 312. The axial flow path 311 is arranged to extend along the central axis of the crankshaft 3 and is connected to the oil storage chamber 121 at one end close to the high-pressure housing 12. The radial flow path 312 is arranged to extend in the radial direction of the crankshaft 3. The inner end of the radial flow path 312 is connected to the axial flow path 311, and the outer end of the radial flow path 312 is formed with a first oil outlet 32. The first oil outlet 32 ​​is used to communicate with the lubrication chamber 6 defined by the first bearing support 41 and the support bearing 5, so that the lubricating oil can flow out from the first oil outlet 32 ​​to lubricate the support bearing 5 on the first bearing support 41.

[0082] Through the above arrangement, the rotation smoothness of the crankshaft 3 can be improved, and the reliability of the compressor 100 can be improved. In addition, during the operation of the compressor 100, the higher the rotation speed of the crankshaft 3, the stronger the centrifugal effect on the lubricating oil in the first oil return channel 31, and the greater the amount of oil entering the lubricating chamber 6 through the first oil outlet 32, so that adaptive adjustment of the oil amount can be achieved.

[0083] In some embodiments of the present invention, the radial flow path 312 can be provided in plurality, and the plurality of radial flow paths 312 can be arranged spaced apart along the circumference of the crankshaft 3. For example, the plurality of radial flow paths 312 can be arranged spaced apart evenly along the circumference of the crankshaft 3, or the plurality of radial flow paths 312 can be arranged spaced apart unevenly along the circumference of the crankshaft 3.
