Description

Technical Field

[0001] This application belongs to the field of air conditioner technology, specifically relating to a gas-liquid separation component, a compressor, and an air conditioner. Background Technology

[0002] With the widespread use of inverter air conditioners, users have increasingly higher requirements for the performance and noise levels of air conditioners. The key component that determines these two factors is the compressor of the outdoor unit. Therefore, improving compressor efficiency and reducing noise are crucial to enhancing the quality of air conditioners.

[0003] The compressor mainly consists of a casing, a pump body, and a motor. The motor itself consists of a stator and a rotor. Figure 17 and 18 As shown, the rotor, connected via the pump body, includes a rotor core, magnets, balance weights, and an oil baffle structure. When the compressor runs, a three-phase power supply is applied to the stator, and the rotating magnetic field drives the rotor to rotate, which, along with the crankshaft, drives the pump body in compression motion. During refrigerant compression, it mixes with refrigeration oil, and the compressed high-pressure gas is discharged and flows into the upper chamber of the compressor through the rotor's flow holes. Simultaneously, after passing through the rotor's flow holes, the high-pressure oil gas is buffered by the oil baffle structure, resulting in refrigerant and refrigeration oil gas-liquid separation.

[0004] When a rotary compressor is running, especially at high frequencies, insufficient oil discharge and incomplete gas-liquid separation can lead to the discharge of refrigerant oil from inside the compressor into the air conditioning system. This makes oil return to the compressor more difficult, resulting in insufficient refrigerant oil, poor lubrication of compressor components, increased wear, and compromised compressor reliability. Furthermore, an increased oil discharge rate increases the amount of refrigerant oil entering the condenser and evaporator, reducing the heat exchange capacity of the air conditioning system and worsening heat exchange conditions, ultimately leading to a decline in the system's performance.

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0073] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

[0075] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0076] See also Figures 1 to 16 As shown, according to an embodiment of this application, a gas-liquid separation assembly includes:

[0077] The motor assembly includes a rotor assembly, wherein the rotor 1 of the rotor assembly is provided with an axially through rotor flow hole 12;

[0078] The first oil baffle 2 is disposed on the rotor assembly and located around the inlet end of the rotor flow hole 12, forming a partial blockage of the rotor flow hole 12; when the first oil baffle 2 rotates with the rotor assembly, it separates the gas and liquid entering the rotor flow hole 12.

[0079] This application has the following beneficial effects:

[0080] An oil baffle is installed near the inlet end of the rotor flow hole 12 to separate the incoming gas and liquid, thereby improving the oil baffle effect, reducing the amount of refrigerant oil entering the air conditioning system, effectively improving the heat exchange efficiency of the air conditioning system, and thus enhancing the system performance.

[0081] Traditional compressors reduce the oil content in exhaust gas by typically installing an oil-blocking structure on the rotor 1 on the outflow side of the rotor flow hole 12. This application installs an oil-blocking component near the inlet end of the rotor flow hole 12, which, combined with the oil-blocking structure on the outflow side, allows the exhaust gas to undergo two oil-blocking actions, achieving oil-gas separation, effectively improving the oil separation effect, and reducing the oil content in the compressor exhaust gas.

[0082] In some implementations...

[0083] The rotor assembly includes a first baffle 4 that abuts against the inlet end of the rotor flow hole 12. The first baffle 4 is provided with a first through hole 41 that is connected to the rotor flow hole 12. The first oil blocking member 2 is provided on the side of the first baffle 4 away from the rotor flow hole 12 and is located at a part of the periphery of the first through hole 41, thus partially blocking the first through hole 41.

[0084] The first oil baffle 2 is placed on the first baffle 4. The first baffle 4 is in contact with the rotor 1. The rotor 1 is provided with a magnet 6 groove 11 to accommodate the magnet 6. The function of the first baffle 4 is to block the magnet 6 and prevent the magnet 6 from falling out of the magnet 6 groove 11. Secondly, it is to prevent the debris and impurities from flying out and affecting the operation of the motor or pump body.

[0085] A first through hole 41 corresponding to the rotor flow hole 12 is provided on the first baffle 4. The first oil baffle 2 is provided on one side of the first through hole 41, which also separates the oil and gas entering the first through hole 41 and the rotor flow hole 12. Since the first oil baffle 2 is directly provided on the first baffle 4, it is an integrated design, which makes assembly simple and reliable and improves production efficiency.

[0086] In some implementations...

[0087] The first oil baffle 2 includes a first rib, which extends radially along the rotor 1 and is curved at one end near the shaft hole 13 of the rotor 1. The curved end matches a portion of the periphery of the rotor flow hole 12. The first rib is arc-shaped along the axial direction of the rotor 1 and the arc bends toward the side where the rotor flow hole 12 is located to form partial obstruction.

[0088] A first oil-blocking element 2 is provided on the first baffle 4. The first oil-blocking element 2 adopts a first rib structure, that is, a rib is provided on the side of the first baffle 4. The rib extends radially along the rotor 1 and partially blocks the rotor flow hole 12 located in the middle of the rotor 1. In this way, the first oil-blocking element 2 is provided on the first baffle 4. Figure 4 , 5 When rotating counterclockwise as shown in Figure 7, the oil-gas mixture is separated under the continuous impact of the first rib, and at the same time, the separated airflow is guided into the rotor flow hole 12.

[0089] In some implementations...

[0090] The height of the first rib along the axial direction of the rotor 1 gradually increases and decreases, and the height is at the position of the rotor flow hole 12.

[0091] To improve the separation effect of the first rib, the first rib is designed with a high middle and low sides to maximize the contact area between the oil and gas and the first rib, thereby improving the separation effect.

[0092] In some implementations...

[0093] The line connecting the center of the rotor flow hole 12 and the center of the rotor 1 is the reference line, and the first rib is located on one side of the reference line; the distance between the end of the first rib away from the rotor flow hole 12 and the reference line is set as a, and the distance between the other end is set as b, satisfying b / a>3.

[0094] The two ends of the first rib are located on the same side of the baseline, but at different distances. This agitates the high-pressure airflow that has been compressed from the pump body, causing the airflow to rise in a vortex and more easily enter the rotor flow hole 12.

[0095] In some implementations...

[0096] The central angle of the arc is set to 30° to 45°.

[0097] The first rib is arc-shaped along the rotor 1 axis. The central angle of this arc is set within this range to better turbulent airflow and improve the oil-throwing effect, as shown in the following figure. Figure 15 As shown.

[0098] In some implementations...

[0099] A first balance block 5 is provided on the side of the first baffle 4 away from the rotor flow hole 12.

[0100] A first balancing block 5 is set on the first baffle 4 to play a balancing role, so that the baffle and the balancing block are integrated into one structure, reducing the number of parts and improving assembly efficiency.

[0101] In some implementations...

[0102] The first oil baffle 2 and the rotor flow hole 12 are provided in multiples, and they correspond one to one; the first balance block 5 is provided in multiples, and is provided between some adjacent first oil baffles 2.

[0103] In the structure where the first baffle 4 is provided with the first oil baffle 2 and the first balance block 5, a structure in which multiple first balance blocks 5 are distributed between adjacent first oil baffles 2 can be used. In this case, the first balance block 5 and the first oil baffle 2 can be integrated into one unit, further reducing the number of parts and improving assembly efficiency.

[0104] In some implementations...

[0105] The gas-liquid separation assembly further includes a second oil baffle 3 disposed on the rotor assembly. The second oil baffle 3 covers the outlet end of the rotor flow hole 12 and has an exhaust port on its side wall. When the second oil baffle 3 rotates with the rotor assembly, it separates the gas and liquid flowing out of the rotor flow hole 12.

[0106] This application also modifies the structure of the oil baffle at the outlet end of the rotor flow hole 12. The outlet end is sealed by a cover buckle that covers the rotor flow hole 12, and an exhaust port is set on the side wall of the second oil baffle 3 for exhaust. In this way, the gas and liquid flowing out from the rotor flow hole 12 impact the inner wall of the second oil baffle 3. Through centrifugal action, the refrigeration oil is horizontally thrown away, realizing oil-gas separation. The separated gas flow is discharged from the exhaust port.

[0107] The gas is disturbed by the high-speed rotating rotor 1, the airflow pulsation is amplified, the aerodynamic noise frequency band is widened, and the noise problem is further aggravated. At the same time, the friction between the airflow and the iron core increases the wind resistance loss, which has an adverse effect on the system energy efficiency. The oil baffle structure must consider the oil baffle effect and the aerodynamic noise problem, and also ensure simple and reliable assembly. Therefore, the reasonable design of the oil baffle structure is particularly important.

[0108] In some implementations...

[0109] The rotor assembly includes a second baffle 7 that abuts against the outlet end of the rotor flow hole 12. The second baffle 7 is provided with a second through hole 71 that is corresponding to and communicates with the rotor flow hole 12. The second oil baffle 3 is provided on the side of the second baffle 7 away from the rotor flow hole 12 and covers the second through hole 71. The exhaust port faces the outer periphery of the rotor 1.

[0110] Similar to the structure of the first oil baffle 2 being located on the first baffle 4, this application also places the second oil baffle 3 on the second baffle 7. The second baffle 7 and the first baffle 4 are located opposite each other at the axial ends of the rotor 1. Their function is to clamp the magnet 6 located in the rotor 1. In this way, the second oil baffle 3 and the second baffle 7 are integrated, reducing the difficulty of parts and assembly operations and improving assembly efficiency.

[0111] In some implementations...

[0112] The second oil baffle 3 includes a hemispherical chamber that covers the outlet end of the rotor flow hole 12. The area of ​​the covering surface of the hemispherical chamber is set as S3, and the flow area of ​​the rotor flow hole 12 is set as S1, satisfying S3 / S1>2.5.

[0113] The second oil baffle 3 adopts a hemispherical chamber structure, which covers the outlet end of the rotor flow hole 12. The hemispherical chamber structure allows airflow to contact its inner wall, and through centrifugal force, the refrigerant oil is horizontally flung away, achieving oil-gas separation. The ratio of the cover area to the flow area of ​​the rotor flow hole 12 is also set to ensure sufficient gas entry into the silencer chamber, aiming to reduce noise. Figure 16 As shown.

[0114] In some implementations...

[0115] The volume of the hemispherical chamber is set as V, and the axial length of the rotor flow hole 12 is set as L, satisfying S1×L<V.

[0116] The inner wall of the hemispherical chamber is curved, so the gas impact on the surface will not produce a sharp sound; the airflow is buffered from the narrow channel to the open spherical cavity, which can effectively reduce noise; by adopting the above-mentioned volume ratio setting, the aerodynamic noise of gas flow can be reduced.

[0117] The noise data generated by the structure of the second oil stop component 3 in this application and the conventional oil stop component are as follows:

[0118]

[0119]

[0120] In some implementations...

[0121] The second oil baffle 3 also includes an exhaust pipe 31 connected to the exhaust port, and the ratio of the volume of the hemispherical chamber to the volume of the exhaust pipe 31 is greater than 3.

[0122] The volume of the exhaust pipe 31 connected to the exhaust of the second oil-blocking component 3 is set so that the airflow enters a small channel. In order to make the refrigeration oil centrifugally fling along the outlet wall of the oil-throwing structure when the airflow is discharged, the refrigeration oil can be centrifugally flung away when the airflow is discharged.

[0123] In some implementations...

[0124] A second balance block 8 is provided on the side of the second baffle 7 away from the rotor flow hole 12.

[0125] A second balancing block 8 is provided on the second baffle 7 to play a balancing role, so that the baffle and the balancing block are integrated into one structure, reducing the number of parts and improving assembly efficiency.

[0126] In some implementations...

[0127] The second oil baffle 3 and the rotor flow hole 12 are provided in multiples, and they correspond one to one; the second balance block 8 is provided in multiples, and is provided between some adjacent second oil baffles 3.

[0128] In the structure in which the second baffle 7 is provided with the second oil baffle 3 and the second balance block 8, multiple second balance blocks 8 are distributed between adjacent second oil baffles 3. In this case, the second balance block 8 and the second oil baffle 3 can be integrated into one unit, further reducing the number of parts and improving assembly efficiency.

[0129] In some implementations...

[0130] The rotor flow holes 12 are provided with N1 holes, the number of pole pairs of the rotor 1 is set to P, and the flow area of ​​each rotor flow hole 12 is set to S1, satisfying that 2P / N1 is an integer and 0 < N1S1 / πR. 2 <0.15.

[0131] Increasing the flow area of ​​a rotary compressor is beneficial for improving compressor performance; however, if the flow area of ​​the rotor flow hole 12 is too large, the motor performance will be affected, thereby reducing the compressor performance. Therefore, the above-mentioned range is set. Figure 12 As shown, the COP of the compressor is related to the size of the flow area of ​​the rotor flow hole 12.

[0132] This application also includes a structure in which a first oil baffle 2 and a second oil baffle 3 are simultaneously provided at both ends of the rotor flow hole 12, such as... Figure 13 and 14A comparison reveals that, compared with the conventional single-barrier structure, the oil-gas cross-sectional distribution diagram of the oil-barrier structure equipped with the first oil-barrier component 2 and the second oil-barrier component 3 is obtained using fluid simulation software. It can be seen that the oil-gas distribution in the central region of the oil-barrier structure of this application is relatively low; while the oil-gas distribution in the central region of the conventional oil-barrier structure is high, indicating poor oil-gas separation. Furthermore, the oil-barrier structure of the first oil-barrier component 2 and the second oil-barrier component 3 has a high oil content in the surrounding areas and a low oil content in the center, thus reducing the oil content in the gas.

[0133] According to another aspect of this application, a compressor is provided, including the gas-liquid separation assembly as described above.

[0134] According to another aspect of this application, an air conditioner is provided, including the gas-liquid separation assembly as described above or the compressor as described above.

[0135] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

[0136] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above description is merely a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
