Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to a compressor and an air conditioner. Background Technology

[0002] The compressor is used to compress refrigerant gas and is the core structure of the air conditioner's heat exchange system, playing a crucial role. The compressor typically contains lubricating oil to lubricate its various components.

[0003] During compressor operation, lubricating oil and refrigerant gas mix to form an oil-gas mixture. In existing technology, compressors typically have a baffle above the exhaust pipe to separate and guide the oil-gas mixture back into the compressor.

[0004] However, during the research of existing technologies, the inventors discovered that the baffle could not completely separate the oil-gas mixture. Some of the oil-gas mixture would still be discharged from the exhaust pipe, causing the lubricating oil to be lost. This resulted in a high oil discharge rate of the compressor, which reduced the lubrication effect on the various components inside the compressor and even caused the compressor to suffer from oil shortage and wear, thus reducing its service life. Summary of the Invention

[0005] In view of the above problems, the present invention is proposed to provide a compressor and air conditioner that overcomes or at least partially solves the above problems.

[0008] The oil-gas separation structure includes an air guide assembly and an extended guide plate. The air guide assembly is connected to the outer periphery of the crankshaft and is interference-fitted with the housing. The rotation of the crankshaft drives a portion of the air guide assembly to rotate, thereby separating a portion of the oil-gas mixture.

[0010] Optionally, the air guiding assembly includes an air guiding shell and a guide plate;

[0011] The air guide housing is connected to the outer periphery of the crankshaft and is interference-fitted with the housing. The guide plate is disposed inside the air guide housing and connected to the outer periphery of the crankshaft. The extension guide plate is connected to the air guide housing and extends toward the motor.

[0012] Optionally, the air guide shell includes a base plate and a side wall connected to the base plate, the side wall having an opening, and the extension guide plate being connected to the base plate at a position opposite to the opening.

[0013] Optionally, the base plate has an opening that is fitted around the outer periphery of the crankshaft.

[0014] Optionally, the extended guide plate is an arc-shaped guide plate.

[0015] Optionally, the guide plate includes a connecting pipe and fan blades;

[0016] The connecting pipe is connected to the outer periphery of the crankshaft, and the fan blade is connected to the side of the connecting pipe away from the crankshaft. The crankshaft drives the connecting pipe to rotate, and the connecting pipe drives the fan blade to rotate. The fan blade separates a portion of the oil-gas mixture.

[0017] Optionally, the number of fan blades may include a plurality of fan blades, which are spaced apart from each other and extend away from the connecting pipe.

[0018] Optionally, the air guiding assembly further includes a cover plate, which is connected to the air guiding shell and surrounds the air guiding shell to form a receiving cavity, and the guide plate is disposed in the receiving cavity.

[0019] Optionally, the cover plate has a through hole, and the guide plate is at least partially exposed through the through hole.

[0020] Optionally, the oil-gas separation structure further includes an oil return pipe, and the housing is provided with a receiving groove;

[0021] The oil return pipe is connected to and communicates with the air guide shell, and extends to the receiving tank to recover the separated oil into the receiving tank.

[0022] Optionally, the compressor further includes an exhaust pipe;

[0023] The exhaust pipe is connected to and communicates with the housing, and is located between the oil-gas separation structure and the motor. The exhaust pipe is used to discharge gas from the compressor.

[0024] Optionally, the extended guide plate is disposed on the side of the guide plate away from the exhaust pipe.

[0025] Optionally, the housing is further provided with a stationary scroll disk and a moving scroll disk. The moving scroll disk is connected to the crankshaft and is located on the side of the oil-gas separation structure away from the motor. The stationary scroll disk is connected to the side of the moving scroll disk away from the oil-gas separation structure.

[0026] Optionally, the housing may further include a first support and a second support;

[0027] The first bracket is connected to the outer periphery of the crankshaft and is located on the side of the motor away from the oil-gas separation structure.

[0028] Secondly, embodiments of this application provide an air conditioner, which includes the aforementioned compressor.

[0029] In this embodiment, the compressor includes a housing and a crankshaft, an oil-gas separation structure, and a motor disposed within the housing. Both the oil-gas separation structure and the motor are connected to the outer periphery of the crankshaft and are spaced apart along the axial direction of the crankshaft. The oil-gas separation structure includes a gas guide assembly and an extended guide plate. The gas guide assembly is connected to the outer periphery of the crankshaft and is interference-fitted with the housing. Rotation of the crankshaft drives a portion of the gas guide assembly to rotate, thereby separating a portion of the oil-gas mixture. The extended guide plate is connected to the gas guide assembly and extends towards the motor. One end of the extended guide plate away from the gas guide assembly is connected to the motor. Another portion of the oil-gas mixture is transferred from the gas guide assembly along the extended guide plate to the motor, where the heat generated by the motor separates the remaining portion of the oil-gas mixture. Thus, the gas guide assembly, rotating with the crankshaft, separates a portion of the oil-gas mixture under centrifugal force, achieving the first separation of the oil-gas mixture. Furthermore, due to the interference fit between the air guide assembly and the housing, a significant portion of the oil-gas mixture within the housing can be separated, preventing some of the oil-gas mixture from being directly discharged from the compressor without passing through the air guide assembly. Then, the remaining portion of the oil-gas mixture that is not completely separated can be transferred to the motor via the extended guide plate. The motor generates heat during operation, which can then further separate the remaining oil-gas mixture, achieving a second separation. This improves the separation rate of the oil-gas mixture, reduces the compressor's oil discharge rate, and allows for the retention of more lubricating oil within the compressor, improving the lubrication of its internal components and extending the compressor's service life. This avoids the problem of insufficient lubricating oil loss that often occurs with baffles, reducing the risk of compressor wear due to oil shortage.

[0043] Reference Figures 1 to 6 This diagram illustrates the structure of a compressor according to an embodiment of this application. Specifically, it may include: a housing 100 and a crankshaft 200, an oil-gas separation structure 300, and a motor 400 disposed within the housing 100. Both the oil-gas separation structure 300 and the motor 400 are connected to the outer periphery of the crankshaft 200, and are spaced apart along the axial direction of the crankshaft 200.

[0044] The oil-gas separation structure 300 includes a gas guide assembly 310 and an extended guide plate 320. The gas guide assembly 310 is connected to the outer periphery of the crankshaft 200 and is press-fitted with the housing 100. The rotation of the crankshaft 200 drives part of the gas guide assembly 310 to rotate, so as to separate part of the oil-gas mixture.

[0045] The extension guide plate 320 is connected to the air guide assembly 310 and extends toward the motor 400. One end of the extension guide plate 320 away from the air guide assembly 310 is connected to the motor 400. Another part of the oil-gas mixture is transferred from the air guide assembly 310 along the extension guide plate 320 to the motor 400 so that the other part of the oil-gas mixture can be separated by the heat generated by the motor 400.

[0046] In this embodiment, the air guide assembly 310 can separate a portion of the oil-gas mixture under centrifugal force as the crankshaft 200 rotates, achieving the first separation of the oil-gas mixture. Furthermore, due to the interference fit between the air guide assembly 310 and the housing 100, a larger portion of the oil-gas mixture within the housing 100 can be separated, preventing some oil-gas mixture from being directly discharged from the compressor without passing through the air guide assembly 310. Then, another portion of the oil-gas mixture that is not completely separated can be transmitted to the motor 400 through the extended guide plate 320. The motor 400 generates heat during operation, which can then be used to further separate the remaining oil-gas mixture, achieving a second separation. This improves the separation rate of the oil-gas mixture, reduces the oil discharge rate of the compressor, allows for the retention of more lubricating oil within the compressor, improves the lubrication of internal components, and extends the compressor's service life. It avoids the problem of insufficient lubricating oil loss caused by using baffles to achieve complete separation of the oil-gas mixture, reducing the risk of oil shortage wear in the compressor.

[0047] Specifically, in this embodiment, the crankshaft 200 can be positioned at the central axis of the housing 100 and extend along the central axis of the housing 100. The motor 400 provides a stable and reliable power source for the operation of the compressor. The housing 100 has a cavity, and the air guide assembly 310 is interference-fitted with the housing 100, which divides the cavity of the housing 100 into an upper cavity and a lower cavity. The oil-gas mixture moves from the upper cavity to the lower cavity under the action of gravity. Through the interference fit between the air guide assembly 310 and the housing 100, the oil-gas mixture in the upper cavity passes through the air guide assembly 310 during its downward movement to the lower cavity, achieving the first oil-gas separation and improving the separation effect of the oil-gas mixture.

[0048] For example, in practical applications, the lubricating oil in the compressor can be FVC68D refrigeration oil, the refrigerant gas can be R410A refrigerant, the compressor's suction pressure under operating conditions can be 0.998 MPa, and the discharge pressure can be 3.393 MPa. Under these conditions, the temperature generated by the motor 400 can be around 85°C. At a temperature of around 85°C, the solubility of the lubricating oil and the refrigerant gas is relatively low, which can achieve a better separation effect on the oil-gas mixture formed by the lubricating oil and the refrigerant gas. In addition, other types of refrigeration oils and other types of refrigerants can be used for the lubricating oil, and the motor 400 can be operated at 80°C or 90°C, etc., so that the heat generated by the motor 400 can achieve a better separation effect on another part of the oil-gas mixture. In this application embodiment, the specific types of lubricating oil and refrigerant gas, as well as the specific temperature and heat generated by the motor 400, are not limited.

[0049] Optionally, in this embodiment, the air guide assembly 310 includes an air guide housing 311 and a guide plate 312. The air guide housing 311 is connected to the outer periphery of the crankshaft 200 and is interference-fitted with the housing 100. The guide plate 312 is disposed inside the air guide housing 311 and connected to the outer periphery of the crankshaft 200. An extension guide plate 320 is connected to the air guide housing 311 and extends toward the motor 400. In this way, the air guide assembly 310 is interference-fitted with the housing 100 through the air guide housing 311, and the air guide assembly 310 is connected to the crankshaft 200 through the guide plate 312. This allows the rotation of the crankshaft 200 to drive the guide plate 312 to move, thereby separating part of the oil-gas mixture through centrifugal force.

[0050] For example, in this embodiment, the air guide shell 311 is adapted to the housing 100. The size of the air guide shell 311 is similar to or the same as the size of the housing 100. The air guide shell 311 can be cylindrical, elliptical, etc. The specific shape of the air guide shell 311 is not limited in this embodiment. The guide plate 312 can extend along the crankshaft 200 toward the outer wall of the housing 100. The guide plate 312 can be arranged perpendicular to the axial direction of the crankshaft 200 so that the guide plate 312 has a large contact area with the oil-gas mixture during the rotation of the crankshaft 200, thus providing better guidance and separation for the oil-gas mixture. The shape of the guide plate 312 can be rectangular or rhomboid, etc. The specific shape of the guide plate 312 is not limited in this embodiment.

[0051] Optionally, in this embodiment, the gas guide shell 311 includes a base plate 301 and a side wall 302 connected to the base plate 301. The side wall 302 has an opening 303, and an extension guide plate 320 is connected to the base plate 301 at a position opposite to the opening 303. This allows another portion of the oil-gas mixture that has not yet been completely separated to be transported through the opening 303 of the side wall 302 along the extension guide plate 320 to the motor 400, whereby the heat generated by the motor 400 enables a second separation of the oil-gas mixture.

[0052] Specifically, in this embodiment, as the crankshaft 200 drives the guide plate 312 to rotate, the guide plate 312 can separate part of the oil-gas mixture, so that the separated oil can be transmitted along the guide plate 312 to the side wall 302 of the air guide shell 311, and then under the action of gravity, the separated oil flows downward to the bottom plate 301, and then the oil can be returned to the oil storage tank 110 through the oil return pipe 330 connected to the bottom plate 301 of the air guide shell 311.

[0053] Optionally, in this embodiment, the base plate 301 is provided with an opening 304, which is sleeved on the outer periphery of the crankshaft 200, so that the air guide shell 311 is also sleeved on the outer periphery of the crankshaft 200, thereby avoiding interference between the air guide shell 311 and the crankshaft 200.

[0054] In this embodiment, the extension guide plate 320 may optionally be an arc-shaped guide plate. This allows the extension guide plate 320 to have better compatibility with the gas guide shell 311 and the shell 100, achieving a better guiding effect on the other part of the oil-gas mixture.

[0055] Specifically, in this embodiment, the guide plate 312 includes a connecting pipe 321 and a fan blade 322. The connecting pipe 321 is connected to the outer periphery of the crankshaft 200, and the fan blade 322 is connected to the side of the connecting pipe 321 away from the crankshaft 200. The crankshaft 200 drives the connecting pipe 321 to rotate, and the connecting pipe 321 drives the fan blade 322 to rotate. The fan blade 322 separates a portion of the oil-gas mixture. In this way, the connecting pipe 321 can be sleeved on the outer periphery of the crankshaft 200, so that the guide plate 312 can be connected to the crankshaft 200, and the fan blade 322 can guide and separate a portion of the oil-gas mixture.

[0056] Optionally, in this embodiment, the number of fan blades 322 includes multiple blades 322, which are spaced apart from each other and extend away from the connecting pipe 321. In this way, a portion of the oil-gas mixture can be separated by multiple fan blades 322 extending away from the connecting pipe 321, thereby further improving the separation efficiency.

[0057] Optionally, in this embodiment, the gas guiding assembly 310 further includes a cover plate 313, which is connected to the gas guiding shell 311 and forms a receiving cavity with the gas guiding shell 311. A guide plate 312 is disposed within the receiving cavity. This allows a portion of the oil-gas mixture to remain within the receiving cavity. The receiving cavity formed by the cover plate 313 and the gas guiding shell 311 provides a certain degree of sealing for the portion of the oil-gas mixture entering the gas guiding shell 311, preventing the portion of the oil-gas mixture inside the gas guiding shell 311 from easily detaching from the guide plate 312 and moving outside the oil-gas separation structure 300.

[0058] Optionally, in this embodiment, the cover plate 313 is provided with a through hole 314, and the guide plate 312 is at least partially exposed through the through hole 314. In this way, the oil-gas mixture can enter the receiving cavity formed by the cover plate 313 and the air guide shell 311 through the through hole 314, and part of the oil-gas mixture is separated under the action of the guide plate 312 in the receiving cavity.

[0059] In some optional embodiments of this application, the oil-gas separation structure 300 further includes an oil return pipe 330, and the housing 100 is provided with a receiving groove 110; the oil return pipe 330 is connected to and communicates with the gas guide shell 311, and extends to the receiving groove 110 to recover the separated oil to the receiving groove 110. Specifically, the receiving groove 110 can be provided at the bottom of the housing 100, and the receiving groove 110 is used to contain refrigeration oil, which is also the oil chamber. The separated oil can be transferred from the gas guide shell 311 to the receiving groove 110 through the oil return pipe 330, realizing the recycling of the oil.

[0060] Optionally, in this embodiment, the compressor further includes an exhaust pipe 120; the exhaust pipe 120 is connected to and communicates with the housing 100, and is disposed between the oil-gas separation structure 300 and the motor 400, and is used to discharge the gas inside the compressor. Because the exhaust pipe 120 is disposed between the oil-gas separation structure 300 and the motor 400, the unseparated oil-gas mixture will not be directly discharged from the compressor housing 100. Instead, after the oil-gas mixture undergoes two separations by the oil-gas separation structure 300, the refrigerant gas in the separated oil-gas mixture is discharged through the exhaust pipe 120.

[0061] Specifically, in this embodiment, the gas guide assembly 310 can perform a first separation of a portion of the oil-gas mixture, separating it into a first oil and a first gas. The first oil can flow back through the oil return pipe 330 to the receiving tank 110 of the compressor for holding lubricating oil. The first gas and another portion of the oil-gas mixture can be transmitted along the extension guide plate 320 to the motor 400. The heat generated by the motor 400 further separates the other portion of the oil-gas mixture into a second oil and a second gas, improving the separation rate of the oil-gas mixture and reducing the oil discharge rate of the compressor. Then, the second oil can flow downward along the motor 400 under gravity back into the receiving tank 110 at the bottom of the housing 100, while also lubricating the motor 400 and reducing wear caused by its operation. Simultaneously, the first gas and the second gas can be discharged from the compressor housing 100 through the exhaust pipe 120.

[0062] In this embodiment, optionally, the extension guide plate 320 is disposed on the side of the guide plate 312 away from the exhaust pipe 120. This allows for a greater distance between the extension guide plate 320 and the exhaust pipe 120, preventing another portion of the oil-gas mixture from being directly discharged from the compressor through the exhaust pipe 120 without secondary separation by the motor 400. This allows the extension guide plate 320 to effectively transmit the other portion of the oil-gas mixture to the motor 400 for further separation. For example, the extension guide plate 320 and the return oil pipe 330 can be spaced apart to avoid interference between them.

[0063] Optionally, in this embodiment, the housing 100 further includes a stationary scroll plate 101 and a moving scroll plate 102. The moving scroll plate 102 is connected to the crankshaft 200 and is located on the side of the oil-gas separation structure 300 away from the motor 400. The stationary scroll plate 101 is connected to the side of the moving scroll plate 102 away from the oil-gas separation structure 300. The stationary scroll plate 101 and the moving scroll plate 102 are used to compress the refrigerant gas. Typically, the stationary scroll plate 101 has an opening 303, through which the compressed refrigerant gas can be discharged and contained in the upper cavity of the housing 100.

[0064] In this embodiment, optionally, the housing 100 further includes a first support 103 and a second support 104. The first support 103 is connected to the outer periphery of the crankshaft 200 and is positioned on the side of the motor 400 away from the oil-gas separation structure 300. The second support 104 is connected to the outer periphery of the crankshaft 200 and is positioned between the moving scroll plate 102 and the oil-gas separation structure 300. Thus, the first support 103 provides relatively stable and reliable support for the structure on the side of the motor 400 away from the oil-gas separation structure 300, i.e., the bottom of the housing 100. Typically, the bottom of the compressor also includes structures such as an oil pump to transfer lubricating oil from the receiving tank 110 to various components within the compressor that require lubrication. The first support 103 supports the oil pump and other structures at the bottom of the compressor. The second support 104 provides relatively stable and reliable support for the moving scroll plate 102 and the stationary scroll plate 101, resulting in good structural stability for the compressor.

[0065] In summary, the compressor described in the embodiments of this application may include at least the following advantages:

[0066] In this embodiment, the compressor includes a housing and a crankshaft, an oil-gas separation structure, and a motor disposed within the housing. Both the oil-gas separation structure and the motor are connected to the outer periphery of the crankshaft and are spaced apart along the axial direction of the crankshaft. The oil-gas separation structure includes a gas guide assembly and an extended guide plate. The gas guide assembly is connected to the outer periphery of the crankshaft and is interference-fitted with the housing. Rotation of the crankshaft drives a portion of the gas guide assembly to rotate, thereby separating a portion of the oil-gas mixture. The extended guide plate is connected to the gas guide assembly and extends towards the motor. One end of the extended guide plate away from the gas guide assembly is connected to the motor. Another portion of the oil-gas mixture is transferred from the gas guide assembly along the extended guide plate to the motor, where the heat generated by the motor separates the remaining portion of the oil-gas mixture. Thus, the gas guide assembly, rotating with the crankshaft, separates a portion of the oil-gas mixture under centrifugal force, achieving the first separation of the oil-gas mixture. Furthermore, due to the interference fit between the air guide assembly and the housing, a significant portion of the oil-gas mixture within the housing can be separated, preventing some of the oil-gas mixture from being directly discharged from the compressor without passing through the air guide assembly. Then, the remaining portion of the oil-gas mixture that is not completely separated can be transferred to the motor via the extended guide plate. The motor generates heat during operation, which can then further separate the remaining oil-gas mixture, achieving a second separation. This improves the separation rate of the oil-gas mixture, reduces the compressor's oil discharge rate, and allows for the retention of more lubricating oil within the compressor, improving the lubrication of its internal components and extending the compressor's service life. This avoids the problem of insufficient lubricating oil loss that often occurs with baffles, reducing the risk of compressor wear due to oil shortage.

[0067] This application also proposes an air conditioner, which includes the aforementioned compressor.

[0068] For example, in the embodiments of this application, the air conditioner can be a wall-mounted air conditioner, a cabinet air conditioner, etc. The specific type of air conditioner is not limited in the embodiments of this application.

[0069] The air conditioner described in this application embodiment may include at least the following advantages:

[0070] In this embodiment, the air conditioner includes a compressor, which comprises a housing, a crankshaft disposed within the housing, an oil-gas separation structure, and a motor. Both the oil-gas separation structure and the motor are connected to the outer periphery of the crankshaft and are spaced apart along the axial direction of the crankshaft. The oil-gas separation structure includes a gas guide assembly and an extended guide plate. The gas guide assembly is connected to the outer periphery of the crankshaft and is interference-fitted with the housing. Rotation of the crankshaft drives a portion of the gas guide assembly to rotate, thereby separating a portion of the oil-gas mixture. The extended guide plate is connected to the gas guide assembly and extends towards the motor. One end of the extended guide plate away from the gas guide assembly is connected to the motor. Another portion of the oil-gas mixture is transferred from the gas guide assembly along the extended guide plate to the motor, where the heat generated by the motor separates the remaining portion of the oil-gas mixture. Thus, the gas guide assembly, rotating with the crankshaft, separates a portion of the oil-gas mixture under centrifugal force, achieving the first separation of the oil-gas mixture. Furthermore, due to the interference fit between the air guide assembly and the housing, a significant portion of the oil-gas mixture within the housing can be separated, preventing some of the oil-gas mixture from being directly discharged from the compressor without passing through the air guide assembly. Then, the remaining portion of the oil-gas mixture that is not completely separated can be transferred to the motor via the extended guide plate. The motor generates heat during operation, which can then further separate the remaining oil-gas mixture, achieving a second separation. This improves the separation rate of the oil-gas mixture, reduces the compressor's oil discharge rate, and allows for the retention of more lubricating oil within the compressor, improving the lubrication of its internal components and extending the compressor's service life. This avoids the problem of insufficient lubricating oil loss that often occurs with baffles, reducing the risk of compressor wear due to oil shortage.
