[0002] The oil separation assembly in the related technology is used to separate oil and gas in refrigerant gas carrying oil. The oil separation assembly includes an oil separation chamber for separating oil and gas. After the refrigerant gas carrying oil enters the oil separation chamber, it will flow along a spiral path in the oil separation chamber. However, the oil at the bottom of the oil separation chamber is prone to fluctuation due to the force, which can easily lead to unstable oil level at the bottom of the oil separation chamber.

[0050] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0051] The oil separation component 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0052] like Figures 1-3 As shown, the oil separation assembly 1 according to an embodiment of the present invention includes a housing 10 and a liquid stabilizing element 20.

[0053] The housing 10 defines an oil separator chamber 11, which has an air inlet channel 13. Refrigerant gas carrying oil is suitable to enter the oil separator chamber 11 through the air inlet channel 13. After oil and gas are separated in the oil separator chamber 11, the refrigerant gas flows out and the oil remains in the oil separator chamber.

[0054] The liquid level stabilizer 20 is installed in the oil separator chamber 11. The liquid level stabilizer 20 is located between the air intake channel 13 and the bottom wall of the oil separator chamber 11. The liquid level stabilizer 20 can stabilize the liquid level of the oil in the oil separator chamber 11 and reduce the possibility of the oil in the oil separator chamber 11 sloshing.

[0055] Specifically, after the refrigerant gas carrying oil enters the oil separator 11, it forms a spiral downward flow path in the area near the side wall of the oil separator 11, and a spiral upward flow path in the middle of the oil separator 11. Due to the different densities of oil and refrigerant gas, under the action of centrifugal force, when the refrigerant gas carrying oil flows along the spiral downward path, the oil carried in the refrigerant gas is thrown to the inner wall of the oil separator 11, while the refrigerant gas flows along the spiral upward path and flows upward out of the oil separator 11, so as to achieve oil-gas separation in the oil separator 11.

[0056] Furthermore, when the oil separation component 1 is applied in the compressor 1000, the refrigerant gas generated by the compressor 1000 is suitable to enter the oil separator chamber 11 through the intake passage 13, where oil-gas separation is achieved, and the oil at the bottom of the oil separator chamber 11 is suitable to flow back into the compressor 1000 through the oil return passage 14.

[0057] When the refrigerant gas flows along a spiral path in the oil separator chamber 11, the oil at the bottom of the oil separator chamber 11 is prone to fluctuation due to the force applied, which can easily cause fluctuations in the oil level at the bottom of the oil separator chamber 11, resulting in an unstable oil level at the bottom of the oil separator chamber 11.

[0058] When the oil level fluctuates, gaps can easily appear between the oil and the wall of the oil separator 11, and gaps can also appear between the oil and the inner wall of the oil return channel 14. At this time, the refrigerant gas in the oil separator 11 can easily enter the inner wall of the oil return channel 14 through the gap between the oil and the inner wall of the oil separator 11, and then flow into the low-pressure side of the compressor 1000, for example, into the liquid storage chamber of the compressor 1000 used to store lubricating oil, thus avoiding affecting the performance and reliability of the compressor 1000.

[0059] In this embodiment, a liquid stabilizer 20 is installed in the oil separator chamber 11. Since the liquid stabilizer 20 is a solid component, it can obstruct the refrigerant gas flowing towards the bottom wall of the oil separator chamber 11. As a result, when the oil at the bottom of the oil separator chamber 11 is subjected to force, it can reduce the fluctuation of the oil at the bottom of the oil separator chamber 11, stabilize the oil level in the oil separator chamber 11, and prevent the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000, for example, into the liquid storage chamber of the compressor 1000 used to store lubricating oil, thus affecting the performance and reliability of the compressor 1000.

[0060] Specifically, the liquid stabilizer 20 is located inside the oil separator chamber 11, and the oil separator chamber 11 is a solid component. When the refrigerant gas flows along a spiral path inside the oil separator chamber 11, at least a portion of the liquid stabilizer 20 is located on the flow path of the refrigerant gas. When the refrigerant gas flows toward the liquid stabilizer 20, the liquid stabilizer 20 can reduce the speed of this portion of the refrigerant gas to reduce the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11. This reduces the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11, reduces the possibility of the refrigerant gas in the oil separator chamber 11 entering the oil return channel 14 through the gap between the oil and the oil separator chamber 11, and reduces the possibility of the refrigerant gas flowing into the low-pressure side of the compressor 1000 through the oil return channel 14.

[0061] Furthermore, when the liquid stabilizer 20 is in contact with the oil at the bottom of the oil separator chamber 11, frictional resistance is formed between the liquid stabilizer 20 and the oil. When the refrigerant gas tends to cause fluctuations in the oil, the oil transmits the force to the liquid stabilizer 20. The liquid stabilizer 20 exerts a force to resist the fluctuations in the oil and converts the kinetic energy of the fluctuations into heat energy through friction to consume the energy of the fluctuations. This can suppress the fluctuations in the oil level at the bottom of the oil separator chamber 11, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11. It also reduces the possibility that the refrigerant gas in the oil separator chamber 11 will enter the oil return channel 14 through the gap between the oil and the oil separator chamber 11, and reduces the possibility that the refrigerant gas will flow into the low-pressure side of the compressor 1000 through the oil return channel 14.

[0062] According to the oil separation component 1 of this utility model embodiment, by providing a liquid stabilizer 20 in the oil separator 11, the problem of unstable oil level at the bottom of the oil separator 11 can be solved, so as to prevent the refrigerant gas in the oil separator 11 from flowing into the return oil channel 14 through the gap between the oil and the oil separator 11, and then into the low-pressure side of the compressor 1000, thereby avoiding affecting the performance and reliability of the compressor 1000.

[0063] The oil separation component 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0064] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the oil separation assembly 1 includes a housing 10 and a liquid stabilizing element 20.

[0065] In some embodiments of this utility model, at least a portion of the liquid stabilizer 20 protrudes from the inner wall of the oil separator chamber 11. When the refrigerant gas flows along a spiral path in the oil separator chamber 11, at least a portion of the liquid stabilizer 20 protruding from the inner wall of the oil separator chamber 11 is located on the flow path of the refrigerant gas. When the refrigerant gas flows toward the liquid stabilizer 20, the liquid stabilizer 20 can reduce the speed of this portion of the refrigerant gas to reduce the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11. This prevents the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000, for example, into the liquid storage chamber of the compressor 1000 used to store lubricating oil, thus affecting the performance and reliability of the compressor 1000.

[0066] In some embodiments of this utility model, such as Figure 7 , Figure 10As shown, the liquid stabilizer 20 extends at least beyond the central axis of the oil separator chamber 11 to ensure that the liquid stabilizer 20 is located on the flow path of the refrigerant gas, thereby ensuring the effect of the liquid stabilizer 20 in slowing down the refrigerant gas. This allows the liquid stabilizer 20 to fully reduce the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11. This prevents the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000, for example, into the liquid storage chamber of the compressor 1000 used to store lubricating oil, which would affect the performance and reliability of the compressor 1000.

[0067] Furthermore, the liquid stabilizer 20 extends at least beyond the central axis of the oil separator chamber 11. When the liquid stabilizer 20 is in contact with the oil at the bottom of the oil separator chamber 11, the contact area between the liquid stabilizer 20 and the oil is guaranteed. This allows the liquid stabilizer 20 to effectively suppress fluctuations in the oil level at the bottom of the oil separator chamber 11, thereby significantly reducing the possibility of fluctuations in the oil level at the bottom of the oil separator chamber 11. This also reduces the possibility of refrigerant gas flowing between the oil and the wall of the oil separator chamber 11, preventing refrigerant gas from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11 due to unstable oil level at the bottom of the oil separator chamber 11, and subsequently into the low-pressure side of the compressor 1000.

[0068] Furthermore, the portion of the liquid stabilizer 20 protruding from the inner wall of the oil separator 11 extends beyond the central axis of the oil separator 11 to ensure the blocking effect of the liquid stabilizer 20 on the airflow, thereby ensuring the speed reduction effect of the liquid stabilizer 20 on the refrigerant gas, so that the liquid stabilizer 20 can be used to fully reduce the force of the refrigerant gas on the oil at the bottom of the oil separator 11.

[0069] In some embodiments of this utility model, such as Figure 10 As shown, the liquid stabilizer 20 cooperates with the inner wall of the oil separator 11 to divide the oil separator 11 into multiple chambers in the horizontal direction. In the horizontal direction, the liquid stabilizer 20 defines the walls of the multiple chambers.

[0070] Specifically, in the horizontal direction, one end of the liquid stabilizer 20 extends and contacts the inner wall of the oil separator 11, thereby dividing the oil separator 11 into multiple chambers in the horizontal direction. This ensures the length of the liquid stabilizer 20, and thus ensures that the liquid stabilizer 20 is located on the flow path of the refrigerant gas, ensuring the effect of the liquid stabilizer 20 in slowing down the refrigerant gas. This effectively reduces the force of the refrigerant gas on the oil at the bottom of the oil separator 11, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator 11 and reducing the possibility of refrigerant gas flowing between the oil and the wall of the oil separator 11. This prevents the refrigerant gas in the oil separator 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator 11 due to unstable oil level at the bottom of the oil separator 11, and then into the low-pressure side of the compressor 1000.

[0071] Furthermore, the portion of the liquid stabilizer 20 protruding from the inner wall of the oil separator 11 cooperates with the inner wall of the oil separator 11 to divide the oil separator 11 into multiple chambers in the horizontal direction.

[0072] In some embodiments of this utility model, such as Figure 3 As shown, the oil separation assembly 1 also includes an oil filter element 30, which is disposed in the oil separation chamber 11. The oil filter element 30 is used to filter the oil flowing to the bottom wall of the oil separation chamber 11 to filter out impurities in the oil.

[0073] Specifically, the refrigerant gas entering the oil separator chamber 11 through the air intake channel 13 may carry impurities, such as iron filings. When the refrigerant gas flows along a spiral path, the impurities in the refrigerant gas are separated from the oil and flow towards the bottom of the oil separator chamber 11 under the action of gravity. The oil filter element 30 can filter the impurities in the oil, thereby reducing the impurities in the oil at the bottom of the oil separator chamber 11.

[0074] In some optional embodiments of this utility model, such as Figure 6 , Figure 7 As shown, the liquid stabilizer 20 is fixed to the oil filter 30, and both the liquid stabilizer 20 and the oil filter 30 are located in the oil separator chamber 11.

[0075] When the refrigerant gas flows toward the liquid stabilizer 20, the liquid stabilizer 20 can slow down this part of the refrigerant gas to reduce the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11. This reduces the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11 and the possibility of refrigerant gas flowing between the oil and the wall of the oil separator chamber 11. This prevents the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11 due to the unstable oil level at the bottom of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000.

[0076] In some specific embodiments of this utility model, the oil filter element 30 defines a filter chamber 31 with a top opening 32. Under the action of centrifugal force, the oil that is thrown onto the wall of the oil separator 11 is suitable to enter the filter chamber 31 through the top opening 32 under the action of gravity, and after being filtered by the oil filter element 30, it flows to the bottom of the oil separator 11.

[0077] The liquid stabilizer 20 is located inside the filter chamber 31. This allows the liquid stabilizer 20 and the oil filter 30 to be installed together in the oil separation chamber 11 when assembling the oil separation assembly 1, which reduces installation steps and lowers costs.

[0078] In some embodiments, such as Figure 7 As shown, in the horizontal direction, one end of the liquid stabilizer 20 is connected to the wall of the filter chamber 31, and the other end is spaced apart from the wall of the filter chamber 31.

[0079] Specifically, the other end of the liquid stabilizer 20 extends beyond the central axis of the filter chamber 31 to ensure the length of the liquid stabilizer 20, so that the liquid stabilizer 20 is located on the flow path of the refrigerant gas. This allows the liquid stabilizer 20 to reduce the speed of the refrigerant gas, thereby reducing the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11. This reduces the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11 and the possibility of refrigerant gas flowing between the oil and the wall of the oil separator chamber 11. It also prevents the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11 due to unstable oil level at the bottom of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000.

[0080] In other embodiments, such as Figure 10 As shown, in the horizontal direction, one end of the liquid stabilizer 20 is connected to the wall of the filter chamber 31, and the other end is connected to the wall of the filter chamber 31, so that the liquid stabilizer 20 has a long length and is located on the flow path of the refrigerant gas. This allows the liquid stabilizer 20 to reduce the speed of the refrigerant gas, thereby reducing the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11. This reduces the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11 and the possibility of refrigerant gas flowing between the oil and the wall of the oil separator chamber 11. It also prevents the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11 due to unstable oil level at the bottom of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000.

[0081] In some embodiments, such as Figure 3As shown, the liquid stabilizer 20 also includes a fixing part 22 and a liquid stabilizer part 21. The liquid stabilizer part 21 protrudes from the inner wall of the oil separator chamber 11. The fixing part 22 extends along the depth direction of the filter chamber 31. One end of the fixing part 22 is connected to the oil filter 30, and the other end is connected to the liquid stabilizer part 21 to fix the liquid stabilizer part 21 in the filter chamber 31. This prevents the liquid stabilizer part 21 from shaking due to impact when the refrigerant gas flows through it, thus ensuring the speed reduction effect of the liquid stabilizer part 21 on the refrigerant gas.

[0082] Specifically, when the refrigerant gas flows along a spiral path in the oil separator chamber 11, the liquid stabilizing section 21 is located on the flow path of the refrigerant gas. When the refrigerant gas flows toward the liquid stabilizing section 21, the liquid stabilizing section 21 can reduce the speed of this part of the refrigerant gas to reduce the force of the refrigerant gas on the oil at the bottom of the oil separator chamber 11. This can reduce the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11 and prevent the refrigerant gas in the oil separator chamber 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000, for example, into the liquid storage chamber of the compressor 1000 used to store lubricating oil, which would affect the performance and reliability of the compressor 1000.

[0083] In some examples, such as Figure 3 , Figure 6 As shown, in the longitudinal section of the oil separator 11, the liquid stabilizer 20 is "L" shaped, the fixing part 22 extends in the vertical direction, and the liquid stabilizer 21 extends in the horizontal direction (it should be understood here that the above direction limitation is only for the convenience of describing the attached drawings and will not limit the actual installation position and direction of the oil separator 1).

[0084] In other examples, such as Figure 9 , Figure 10 As shown, in the longitudinal section of the oil separator 11, the liquid stabilizer 20 is quadrilateral, such as rectangular or trapezoidal. One end of the liquid stabilizer 20 in the horizontal direction defines a fixing part 22, which extends in the vertical direction. The lower end of the liquid stabilizer 20 defines a liquid stabilizer part 21, which extends in the horizontal direction.

[0085] In some embodiments, such as Figure 3 , Figure 6 As shown, the oil filter element 30 includes a filter part 301 and a support part 302. The support part 302 is supported on the oil separator chamber 11, and the filter part 301 is disposed on the support part 302. The filter part 301 defines the filter chamber 31. The oil filter element 30 is fixed in the oil separator chamber 11 by the support part 302, so that the filter part 301 can smoothly filter the oil flowing into the filter chamber 31 to filter out impurities in the oil.

[0086] It should be explained here that the above-mentioned fixing part 22 extends in the vertical direction, which means that the fixing part 22 can extend in a straight line in the vertical direction, or it can extend tilted to the left or right in the vertical direction. No further restrictions are imposed here.

[0087] In some embodiments, the support 302 is interference-fitted with the side wall of the oil separator 11. This not only fixes the oil filter 30 and the liquid stabilizer 20 in the oil separator 11, but also reduces the gap between the support 302 and the side wall of the oil separator 11, thus reducing the possibility of oil flowing to the bottom of the oil separator 11 through the gap between the support 302 and the side wall of the oil separator 11, and ensuring the filtering effect of the oil filter 30 on the oil.

[0088] In some examples, a sealing ring is provided between the support 302 and the side wall of the oil separator 11 to seal the gap between the support 302 and the side wall of the oil separator 11, thereby reducing the possibility of oil flowing to the bottom of the oil separator 11 through the gap between the support 302 and the side wall of the oil separator 11, which helps to ensure the filtering effect of the oil filter element 30 on the oil.

[0089] In some examples, the filter section 301 is a filter screen, and the side wall and bottom wall of the filter chamber 31 are provided with multiple filter holes. The oil entering the filter chamber 31 from the top opening 32 is suitable to flow to the bottom of the oil separator 11 after being filtered by the bottom wall and side wall of the filter chamber 31.

[0090] Specifically, the bottom and side walls of the filter chamber 31 are provided with filter holes, which makes it easier to increase the area of ​​the oil filter element 30 used for filtering oil, thereby improving the filtration efficiency of the oil filter element 30.

[0091] In some examples, such as Figure 3 As shown, one end of the fixing part 22 is connected to the support part 302, and the other end of the fixing part 22 is connected to the liquid stabilizing part 21, so that the fixing part 22 can fix the liquid stabilizing part 21 in the filter chamber 31, so that the liquid stabilizing part 21 can stabilize the liquid level of the oil at the bottom of the oil separator 11 and reduce the possibility of the liquid level of the oil at the bottom of the oil separator 11 swaying.

[0092] Furthermore, the fixing part 22, the liquid stabilizing part 21 and the supporting part 302 are integrally formed, which makes it easier to reduce the number of parts, reduce the complexity of assembling the oil separation component 1, and reduce costs.

[0093] In some specific embodiments of this utility model, such as Figure 3As shown, the liquid stabilizing part 21 is attached to the bottom wall of the filter chamber 31 so that the liquid stabilizing part 21 is close to the oil at the bottom of the oil separator chamber 11, thereby making it easier for the liquid stabilizing part 21 to come into contact with the oil level at the bottom of the oil separator chamber 11. This creates frictional resistance between the liquid stabilizing part 21 and the oil at the bottom of the oil separator chamber 11, and also creates frictional resistance between the bottom wall of the filter chamber 31 and the oil at the bottom of the oil separator chamber 11.

[0094] When the refrigerant gas tends to cause fluctuations in the oil, the oil transmits the force to the stabilizing section 21 and the oil filter 30. The stabilizing section 21 and the oil filter 30 exert a force against the fluctuations in the oil and convert the kinetic energy of the fluctuations into heat energy through friction to consume the energy of the fluctuations. This can suppress the fluctuations in the liquid level, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator chamber 11 and reducing the possibility of refrigerant gas flowing between the oil and the wall of the oil separator chamber 11. This prevents the refrigerant gas in the oil separator chamber 11 from flowing into the return oil channel 14 through the gap between the oil and the inner wall of the oil separator chamber 11 due to the unstable oil level at the bottom of the oil separator chamber 11, and then into the low-pressure side of the compressor 1000.

[0095] In some embodiments, on the cross-section of the oil separator 11, the liquid stabilizing part 21 protrudes from the inner wall of the oil separator 11, and the shape of the liquid stabilizing part 21 is rectangular.

[0096] In some embodiments, the shape of the liquid stabilizer 20 is polygonal in the longitudinal section of the oil separator 11.

[0097] Furthermore, the shape of the liquid stabilizing part 21 can be rectangular, triangular, or trapezoidal.

[0098] In some embodiments, the shape of the liquid stabilizer 20 in the longitudinal section of the oil separator 11 is circular or fan-shaped.

[0099] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the housing 10 is also provided with an oil return channel 14, which is located at the bottom of the oil separator 11 and communicates with the oil separator 11. The oil at the bottom of the oil separator 11 is suitable to flow to a designated area through the oil return channel 14.

[0100] In the oil separator 11, the oil return channel 14 is located below the air intake channel 13, and the liquid stabilizer 20 is higher than the upper end of the oil return channel 14.

[0101] Specifically, the oil in the oil separator chamber 11 is suitable to fill the return oil channel 14, so that the liquid stabilizer 20 is higher than the return oil channel 14, so that the liquid stabilizer 20 adapts to the height of the liquid level in the oil separator chamber 11, and the liquid stabilizer 20 can stabilize the liquid level.

[0102] The refrigerant gas flowing from the intake passage 13 to the oil separator 11 forms a spiral downward flow path in the area near the side wall of the oil separator 11, and a spiral upward flow path in the middle of the oil separator 11. The return oil passage 14 is located below the intake passage 13 to prevent the refrigerant gas from the intake passage 13 to the oil separator 11 from directly agitating the oil in the return oil passage 14.

[0103] Specifically, the liquid stabilizer 20 is mainly used to slow down the refrigerant gas flowing along the spiral downward path in the area near the side wall of the oil separator 11, so that the liquid stabilizer 20 is higher than the oil return channel 14. This ensures that the refrigerant gas flowing along the spiral downward path in the area near the side wall of the oil separator 11 can be sufficiently slowed down before flowing into the oil return channel 14. This reduces the force of the refrigerant gas on the oil at the bottom of the oil separator 11, thereby reducing the possibility of fluctuations in the oil at the bottom of the oil separator 11 and reducing the possibility of refrigerant gas flowing between the oil and the wall of the oil separator 11. This prevents the refrigerant gas in the oil separator 11 from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator 11 due to unstable oil level at the bottom of the oil separator 11, and then into the low-pressure side of the compressor 1000.

[0104] In some embodiments, the oil in the oil separator 11 is lubricating oil. The lubricating oil at the bottom of the oil separator 11 is suitable to flow to the liquid storage chamber of the compressor 1000 through the oil return channel 14. The lubricating oil in the liquid storage is used to lubricate the components. The liquid storage chamber is connected to the compression chamber 51 of the compressor 1000 so as to lubricate the stationary scroll 61 and the moving scroll 62 of the compressor 1000.

[0105] In this process, the refrigerant gas is compressed in the compression chamber 51 of the compressor 1000 and then enters the oil separator chamber 11 through the intake passage 13. Since there is lubricating oil in the compression chamber 51, the refrigerant gas in the compression chamber 51 will carry some lubricating oil as it enters the oil separator chamber 11. The refrigerant gas entering the oil separator chamber 11 forms a spiral downward flow path in the area near the side wall of the oil separator chamber 11 and a spiral upward flow path in the middle of the oil separator chamber 11. Since the density of oil is greater than that of refrigerant gas, when the refrigerant gas flows along the spiral downward path in the area near the side wall of the oil separator chamber 11, the oil is thrown to the inner wall of the oil separator chamber 11, and the refrigerant gas is discharged from the top of the oil separator chamber 11 along the spiral upward path in the middle of the oil separator chamber 11.

[0106] If the oil at the bottom of the oil separator 11 fluctuates due to the force applied, it will cause the oil level in the return oil channel 14 to fluctuate as well. When a gap appears between the oil and the inner wall of the oil separator 11 and between the oil and the wall of the return oil channel 14, the refrigerant gas in the oil separator 11 will flow into the return oil channel 14 through the gap between the oil and the inner wall of the oil separator 11, and then flow into the low-pressure side of the compressor 1000. This will affect the flow of refrigerant gas in the oil separator 11 and affect the oil separation effect of the oil separation component 1.

[0107] This invention solves the problems of unstable oil level at the bottom of the oil separator 11 and unstable oil level in the return oil channel 14 by setting a liquid stabilizer 20 in the oil separator 11. This prevents the refrigerant gas in the oil separator 11 from flowing into the return oil channel 14 through the gap between the oil and the inner wall of the oil separator 11, and then into the low-pressure side of the compressor 1000. This avoids affecting the smooth flow of refrigerant gas in the oil separator 11, thus ensuring the oil separation component 1's effect on oil-gas separation.

[0108] In some embodiments of this utility model, such as Figure 2 As shown, the oil separator chamber 11 has an outlet 12. The oil separation assembly 1 also includes a liquid separator pipe 40, which is disposed inside the oil separator chamber 11. The liquid separator pipe 40 has an outlet channel 41, which is connected to the outlet 12 and the oil separator chamber 11. The outer peripheral wall of the liquid separator pipe 40 is spaced apart from the inner peripheral wall of the oil separator chamber 11. The refrigerant gas entering the oil separator chamber 11 from the inlet channel 13 is adapted to form a spiral downward flow path between the outer peripheral wall of the liquid separator pipe 40 and the inner peripheral wall of the oil separator chamber 11, and a spiral upward flow path in the middle of the oil separator chamber 11. The spiral upward refrigerant gas is adapted to be discharged from the outlet 12 along the outlet channel 41.

[0109] Specifically, by setting a liquid separator 40 in the oil separation chamber 11, the liquid oil entrained in the gas phase can be efficiently separated and discharged, thereby improving the oil separation component 1's effect on oil-gas separation.

[0110] In some embodiments, the liquid separator 40 is interference-supported in the oil separator chamber 11 to fix the liquid separator 40 in the oil separator chamber 11 and ensure the purity of the refrigerant gas at the outlet 12.

[0111] In some embodiments, such as Figure 2 As shown, the liquid separator 40 is a cyclone oil separator, which can form a spiral downward flow path between the outer peripheral wall of the liquid separator 40 and the inner peripheral wall of the oil separator 11, thereby using centrifugal force to separate the oil and refrigerant gas. At the same time, a spiral upward flow path is formed in the middle of the oil separator 11 and in the gas outlet channel 41, so that the separated refrigerant gas can be discharged from the gas outlet 12 along the gas outlet channel 41.

[0112] Specifically, the outlet of the intake channel 13 is connected to the inner peripheral wall of the oil separator 11 along the tangential direction, so that the oil-gas mixture in the intake channel 13 enters the space between the inner peripheral wall of the oil separator 11 and the outer peripheral wall of the liquid separator 40 along the tangential direction. At this time, the oil-gas mixture is forced to be given a tangential initial velocity. At the same time, under the action of gravity, the oil-gas mixture between the inner peripheral wall of the oil separator 11 and the outer peripheral wall of the liquid separator 40 flows along a spiral downward flow path. During the flow of the oil-gas mixture, centrifugal force is used to separate the oil and the refrigerant gas.

[0113] Meanwhile, as the oil-gas mixture flows along a spiral downward flow path, a high-pressure zone is formed between the outer peripheral wall of the liquid separator 40 and the inner peripheral wall of the oil separator 11, and a low-pressure zone is formed in the middle of the oil separator 11. Driven by the pressure gradient, the refrigerant gas after oil-gas separation forms a spiral upward flow path in the middle of the oil separator 11 and flows out from the gas outlet 12 along the liquid separator 40.

[0114] In some examples, the cyclone separator includes a cylindrical section and a frustum section, the frustum section being connected to the outlet 12, and the inner wall of the frustum section extending outward at an angle toward the outlet 12.

[0115] In this section, part of the outer wall of the frustum section is opposite to the outlet of the air intake channel 13. In the downward direction, the diameter of the frustum section gradually decreases, forcing the rotation radius of the spiraling downward external swirling flow to decrease. According to the conservation of angular momentum, as the rotation radius decreases, the tangential velocity increases accordingly, thereby enhancing the centrifugal force on the gas-liquid mixture and achieving sufficient separation of oil and gas.

[0116] In some optional embodiments of this utility model, such as Figure 2 As shown, the liquid stabilizer 20 is disposed between the liquid distribution pipe 40 and the bottom wall of the oil distribution chamber 11. When the refrigerant gas between the outer peripheral wall of the liquid distribution pipe 40 and the inner peripheral wall of the oil distribution chamber 11 flows down the spiral flow path to the bottom wall of the oil distribution chamber 11, the liquid stabilizer 20 can obstruct the flow of the refrigerant gas to the bottom wall of the oil distribution chamber 11. In turn, when the oil at the bottom of the oil distribution chamber 11 is subjected to force, the liquid stabilizer 20 can reduce the fluctuation of the oil at the bottom of the oil distribution chamber 11 and stabilize the liquid level of the oil in the oil distribution chamber 11.

[0117] In some specific embodiments of this utility model, such as Figure 2 As shown, the minimum distance between the liquid stabilizer 20 and the bottom wall of the oil separator 11 is less than the minimum distance between the liquid stabilizer 20 and the separator 40, so as to reserve enough space between the liquid stabilizer 20 and the separator 40. In this way, when the oil and gas are separated by centrifugal force, a stable spiral downward flow path can be formed between the outer peripheral wall of the separator 40 and the inner peripheral wall of the oil separator 11, so as to avoid the liquid stabilizer 20 affecting the formation of this path.

[0118] Specifically, the liquid stabilizer 20 is located above the bottom wall of the oil separator 11, the liquid separator pipe 40 is located above the liquid stabilizer 20, the distance between the lower end of the liquid stabilizer 20 and the bottom wall of the oil separator 11 is H1, and the distance between the lower end of the liquid separator pipe 40 and the upper end of the liquid stabilizer 20 is H2, where H2 > H1.

[0119] Furthermore, by ensuring that H1 < H2, the distance between the liquid stabilizer 20 and the oil at the bottom of the oil separator 11 can be guaranteed, allowing the liquid stabilizer 20 to easily contact the oil at the bottom of the oil separator 11. This suppresses fluctuations in the oil level at the bottom of the oil separator 11, thereby significantly reducing the possibility of fluctuations in the oil level at the bottom of the oil separator 11. It also reduces the possibility of refrigerant gas flowing between the oil and the wall of the oil separator 11, preventing refrigerant gas from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator 11 due to unstable oil level at the bottom of the oil separator 11, and subsequently into the low-pressure side of the compressor 1000.

[0120] The compressor 1000 according to an embodiment of the present invention is described below. The compressor 1000 according to an embodiment of the present invention includes a compression component 5 and an oil separation assembly 1 according to the above embodiment of the present invention.

[0121] The compression component 5 includes a compression chamber 51, which is provided with an exhaust port 52. The oil separation component 1 is fixed to the compression component 5. The exhaust port 52 is connected to the air intake channel 13. The refrigerant gas compressed in the compression chamber 51 is suitable to enter the oil separation chamber 11 through the air intake channel 13. After oil-gas separation is achieved in the oil separation chamber 11, the refrigerant gas is discharged from the exhaust port 12, and the oil remains in the oil separation chamber 11.

[0122] According to the present invention, the compressor 1000, by utilizing the oil separation assembly 1 of the above embodiment of the present invention and by providing a liquid stabilizing element 20 in the oil separator 11, can solve the problem of unstable oil level at the bottom of the oil separator 11, thereby preventing refrigerant gas in the oil separator 11 from flowing into the oil return channel 14 through the gap between the oil and the oil separator 11, and then into the low-pressure side of the compressor 1000, thus avoiding affecting the performance and reliability of the compressor 1000.

[0123] In some embodiments of this utility model, the housing 10 and the compression component 5 define an exhaust chamber 53, which is connected to the oil separator 11 and the exhaust port 52 respectively. The refrigerant gas in the compression chamber 51 enters the exhaust chamber 53 through the exhaust port 52, and the refrigerant gas in the exhaust chamber 53 enters the oil separator 11 through the air inlet channel 13. After the oil and gas are separated in the oil separator 11, the refrigerant gas is discharged from the air outlet 12, and the oil remains in the oil separator 11.

[0124] Specifically, the housing 10 is sealed to the compression component 5 and defines the exhaust chamber 53. This eliminates the need for additional components between the exhaust port 52 and the intake passage 13 of the compression component 5. The exhaust port 52 and the intake passage 13 can be connected by the exhaust chamber 53 defined by the housing 10 and the compression component 5, which helps to reduce the complexity of the compressor 1000 components.

[0125] In some embodiments of this utility model, such as Figure 11 As shown, the compression component 5 includes a stationary scroll 61 and a moving scroll 62. The stationary scroll 61 and the moving scroll 62 cooperate to define the compression chamber 51. The stationary scroll 61 is provided with an exhaust port 52. The oil separation component 1 is fixed to the side of the stationary scroll 61 away from the moving scroll 62. When the moving scroll 62 rotates eccentrically, the moving scroll 62 and the stationary scroll 61 can compress the refrigerant gas in the compression chamber 51. The compressed refrigerant gas flows along the compression chamber 51 to the exhaust port 52, and enters the oil separator chamber 11 through the intake channel 13 from the exhaust port 52. After oil-gas separation in the oil separator chamber 11, it flows out from the exhaust port 12.

[0126] In some embodiments, the housing 10 is disposed over one end of the exhaust port 52 of the compression component 5 to form an end cap of the compression component 5.

[0128] According to the vehicle of the present invention, by using the compressor 1000 of the above embodiment of the present invention, by providing a liquid stabilizer 20 in the oil separator 11, the problem of unstable oil level at the bottom of the oil separator 11 can be solved, and the refrigerant gas in the oil separator 11 can be prevented from flowing into the oil return channel 14 through the gap between the oil and the inner wall of the oil separator 11 due to the unstable oil level at the bottom of the oil separator 11, and then into the low-pressure side of the compressor 1000.
