Description

Technical Field

[0001] This invention relates to the field of noise reduction structure technology, and in particular to an oil-gas separation noise reduction component and its working method, as well as a compressor. Background Technology

[0002] During the operation of a refrigerator compressor, lubricating oil enters the refrigerant gas path through various means. Specifically, some lubricating oil is drawn into the refrigerant gas path through splashing or atomization. When the compressor cylinders discharge gas, this oil mist enters the cylinder head with the refrigerant flow and flows through specially designed vents to the exhaust muffler chamber on the cylinder seat. During this process, most of the oil mist adheres to the inner wall of the muffler chamber. Due to gravity, it gradually accumulates at the bottom of the muffler chamber. Over time, this accumulation of oil mist reduces the effective volume of the muffler chamber, significantly affecting the silencing effect and potentially increasing the compressor's noise level, which negatively impacts the user experience.

[0003] Meanwhile, a small amount of lubricating oil is discharged from the compressor along with the gas and enters the refrigerator's refrigeration system. This lubricating oil continues to circulate in the system and may adhere to the surface of the heat exchanger. This leads to an increase in the thermal resistance of the heat exchanger, thereby reducing heat exchange efficiency and ultimately affecting the overall performance and energy efficiency of the refrigerator. Especially with the increasing prevalence of high-efficiency inverter compressors, the oil discharge problem has become more prominent and urgently needs to be solved.

[0004] Therefore, it is necessary to design a new component to improve the compressor's noise reduction, reduce lubricant discharge, and ensure the high efficiency of the refrigeration system. Summary of the Invention

[0037] In existing technology, when a refrigerator compressor is running, lubricating oil enters the refrigerant gas path through splashing and atomization, and is then drawn into the cylinder head. As the gas is discharged, the oil mist adheres to the inner wall of the silencing cavity, and gravity causes it to gradually accumulate at the bottom. This accumulation reduces the effective volume of the silencing cavity, potentially leading to increased noise levels and affecting the user experience. Simultaneously, some lubricating oil is discharged with the gas and enters the refrigeration system, possibly adhering to the surface of the heat exchanger. Ultimately, this increases the thermal resistance of the heat exchanger, reduces thermal efficiency, and thus affects the overall performance and energy efficiency of the refrigerator.

[0038] Therefore, embodiments of the present invention provide an oil-gas separation silencing component and its working method, as well as a compressor, to improve the silencing effect of the compressor, reduce the amount of lubricating oil discharged, and ensure the high efficiency performance of the refrigeration system.

[0039] Specifically, the oil-gas separation and silencing assembly includes a cylinder seat exhaust structure 1 and a valve body structure 2, and is equipped with multiple silencing chambers and an oil collection and drainage structure. An oil-blocking structure is installed inside the assembly to prevent the backflow of the oil-gas mixture. Through compressor exhaust, the oil-gas mixture passes through the silencing chambers, and oil droplets are deposited under gravity and discharged through the oil collection and drainage structure. The assembly is also equipped with a silencing chamber cover 4 and a sealing gasket 3 to improve sealing and efficiency. The overall design aims to reduce noise and effectively separate oil and gas.

[0040] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0041] Please see Figures 1 to 4 The aforementioned oil-gas separation and silencing component includes: a cylinder seat exhaust structure 1 and a valve body structure 2. The cylinder seat exhaust structure 1 is provided with a vent 11, a first silencing chamber 121, a second silencing chamber 122, and an oil collection and drainage structure. The vent 11 is connected to the first silencing chamber 121, and the second silencing chamber 122 is connected to the first silencing chamber 121. The oil collection and drainage structure is connected to the first silencing chamber 121 and the second silencing chamber 122 respectively. An oil baffle structure is provided in the first silencing chamber 121 and the second silencing chamber 122 respectively. The valve body structure 2 is connected to the oil collection and drainage structure.

[0042] In this embodiment, when the compressor discharges, the oil-gas mixture enters the first silencing chamber 121 through the vent 11. Inside the first silencing chamber 121, the oil-gas mixture encounters the oil-blocking structure and impacts, causing oil droplets to deposit downwards due to gravity. Simultaneously, the airflow passes through the second silencing chamber 122, further reducing noise. The oil droplets in the first and second silencing chambers 121 are collected and discharged through the oil collecting and draining structure. When the oil droplets accumulate to a set amount, the oil collecting and draining structure will discharge them, maintaining normal system operation.

[0043] The design of the silencing cavity effectively reduces the noise during equipment operation and improves the comfort of the working environment; the oil-blocking structure and the oil collection and drainage system work together to efficiently separate the oil-gas mixture, ensuring the operating efficiency of the equipment; by effectively separating oil and gas, the pollution of gas transmission pipelines by oil is reduced, which helps to extend the service life of the equipment; the reasonable design structure facilitates daily maintenance and repair, and improves the reliability of the equipment.

[0044] In one embodiment, please refer to Figure 2 The aforementioned vent 11 is inserted into the first silencing cavity 121 at a certain angle and is tangent to the cylindrical wall and bottom surface of the first silencing cavity 121. This angle design is limited by the dimensions of the compressor cylinder head exhaust passage and cylinder seat. Furthermore, both the first silencing cavity 121 and the second silencing cavity 122 have a cylindrical structure.

[0045] When the compressor is running, the oil-gas mixture enters the first silencer chamber 121 through the inclined vent 11. Due to the inclined design of the vent 11, the airflow changes when entering the first silencer chamber 121, which enhances the dispersion effect of the airflow and reduces noise. In the first silencer chamber 121, the oil droplets in the mixture settle downwards due to gravity, forming liquid oil, while the gas continues to flow to the second silencer chamber 122. When the airflow passes through the second silencer chamber 122, the noise is further reduced and the final purification process is completed.

[0046] The inclined vent 11 design improves airflow diffusion and helps to significantly reduce noise during equipment operation; the cylindrical cavity design makes the separation of oil-gas mixture more efficient and ensures that oil droplets can settle effectively.

[0047] In one embodiment, please refer to Figure 1 and Figure 2 The aforementioned oil-blocking structure includes several oil-blocking ribs 17 that are inclined along the direction close to the bottom of the first silencing cavity 121 or the bottom of the second silencing cavity 122. One side of the several oil-blocking ribs 17 is connected to the side wall of the first silencing cavity 121 or the side wall of the second silencing cavity 122. The several oil-blocking ribs 17 are arranged radially.

[0048] One side of the oil baffle 17 is connected to the cavity wall, increasing the contact area between the oil-gas mixture and the cavity wall. When the oil-gas mixture enters the silencing cavity, the presence of the oil baffle 17 changes the airflow, increasing the contact between the oil droplets and the cavity wall, thereby effectively promoting the sedimentation and separation of the oil droplets. The inclined design of the oil baffle 17 blocks the direct inflow of gas, helps guide the gas flow, and ensures that the oil droplets can be better collected, preventing them from escaping with the airflow. The protrusion height of the oil baffle 17 is generally set between 0.01 and 5 mm to ensure that it does not cause excessive resistance to exhaust while effectively improving the oil baffle effect.

[0049] By increasing the contact area between the oil-gas mixture and the walls of the silencing cavity, the airflow impacts all contact surfaces at high speed within the cavity. Oil droplets, under gravity, flow downstream along the contact surfaces and deposit at the bottom of the silencing cavity. This design achieves excellent oil-gas separation, significantly reducing the oil content in the gas discharged from the silencing cavity, thereby minimizing the impact of oil on the refrigerator's refrigeration system.

[0050] The optimized airflow path reduces noise from gas flow, improving the overall quietness of the equipment's operation; the reasonable oil baffle 17 design avoids excessive exhaust resistance, ensuring smooth exhaust while the equipment operates efficiently; effective oil-gas separation reduces oil corrosion of the refrigeration system, thus helping to extend the equipment's service life; the simple design makes system maintenance more convenient and reduces maintenance costs.

[0051] In other embodiments, the aforementioned oil baffles 17 are arranged in a spiral oblique manner, or in other shapes. The arrangement should be opposite to the airflow and should increase the inner wall surface of the silencing cavity.

[0052] In one embodiment, please refer to Figure 3 The cylinder block exhaust structure 1 described above is also provided with a connecting port 13, through which the first muffler chamber 121 and the second muffler chamber 122 are connected.

[0053] The compressor exhaust enters the first silencer chamber 121 through the vent 11 and enters the second silencer chamber 122 through the connecting port 13. Due to the different cross-sectional areas of the exhaust channels, the purpose of two-stage expansion silencer can be achieved.

[0054] In one embodiment, please refer to Figures 1 to 4 The aforementioned oil collection and drainage structure includes an oil collection port 14, a connecting channel 19, a sliding groove 15, and an oil leakage hole 16. The bottom of the first silencer chamber 121 and the bottom of the second silencer chamber 122 are respectively provided with oil collection ports 14, and the bottoms of the two oil collection ports 14 are respectively connected to the connecting channel 19. The sliding groove 15 is placed inside the cylinder seat exhaust structure 1, and the sliding groove 15 is connected to the connecting channel 19. The valve body structure 2 is placed inside the sliding groove 15, and the oil leakage hole 16 is located at the bottom of the connecting channel 19. The sliding groove 15 is vertically connected to the connecting port 13. Therefore, the up-and-down movement of the valve body structure 2 built into the sliding groove 15 can adjust the opening degree of the connecting port 13.

[0055] Specifically, the first silencing cavity 121 and the second silencing cavity 122 are symmetrically arranged at the bottom near the connecting port 13 with downward inclined oil collection ports 14 of the first silencing cavity 121 and the second silencing cavity 122. The oil collection ports 14 of the first silencing cavity 121 and the second silencing cavity 122 are the oil collection ports 14 mentioned above. The two oil collection ports 14 are connected at the bottom and communicate with the slide groove 15.

[0056] In this embodiment, the oil collection port 14 is inclined downward so that oil droplets can flow from the oil collection port 14 into the connecting channel 19.

[0057] In this embodiment, the connecting channel 19 is curved in an arc shape, and an oil leakage hole 16 is provided at the lowest point.

[0058] First screw holes 18 are respectively provided at the bottom middle position of the first silencing cavity 121 and the second silencing cavity 122.

[0059] In one embodiment, the valve body structure 2 described above is located directly above the oil leakage hole 16.

[0060] In this embodiment, within the first silencing chamber 121 and the second silencing chamber 122, the oil-gas mixture is subjected to high-speed impacts against the walls, promoting the separation of oil droplets and gas. The deposited lubricating oil accumulates at the bottom of the first and second silencing chambers 121 and flows from the oil collection port 14 into the connecting channel 19. When a certain amount of lubricating oil accumulates in the connecting channel 19, the valve body structure 2 moves upward axially due to buoyancy. This upward movement of the valve body structure 2 opens the bottom oil leakage hole 16, allowing lubricating oil to drip out until the oil level drops to the lower limit of the valve body structure 2. The valve body structure 2 then moves downward, ultimately sealing the oil leakage hole 16. This cyclical process allows the system to effectively discharge excess lubricating oil while maintaining the normal operation of the silencing chambers.

[0061] By increasing the contact area and gravity, oil and gas can be effectively separated, improving separation efficiency and thus reducing the oil content in the compressor exhaust. The floating design of valve body structure 2 automates the lubricating oil discharge process without manual intervention, improving the system's reliability and ease of operation.

[0062] Reducing the oil content in the compressor exhaust helps protect the refrigerator's refrigeration system. Less oil has a negative impact on the refrigeration effect, thereby improving refrigeration efficiency and system lifespan. The arc design of the connecting channel 19 and the setting of the slide groove 15 make the oil-gas separation and discharge process smoother, ensuring the overall performance and stability of the system.

[0063] Through the above design, this structure can achieve efficient oil and gas separation, ensuring the normal operation of the equipment and extending its service life.

[0064] In one embodiment, please refer to Figure 5 The valve body structure 2 described above includes a valve body main section 21 and a valve body sealing section 22. One end of the valve body main section 21 is connected to one end of the valve body sealing section 22. The valve body main section 21 is placed in the slide groove 15.

[0065] The valve body main section 21 and the inner wall of the slide groove 15 are fitted with a very small clearance, and the valve body structure 2 can be axially displaced; the valve body sealing section 22 needs to cover the oil leakage hole 16 to achieve the function of sealing the cavity, but it cannot completely overlap with the top of the oil leakage hole 16, otherwise it cannot move and rise under the action of buoyancy.

[0066] In one embodiment, the valve body structure 2 is a plastic part, the main body section 21 is columnar, and the valve body sealing section 22 is hemispherical.

[0067] Of course, in other embodiments, the valve body structure 2 may also be of other shapes, which need to be changed in sync with the slide groove 15 and the oil leakage hole 16;

[0068] In other embodiments, the valve body structure 2 may also be made of other lightweight materials with very low density.

[0069] Specifically, the valve body consists of a main body section 21 and a sealing section 22. A small gap is maintained between the main body section and the inner wall of the slide groove 15, allowing for axial displacement. When in the appropriate position, the sealing section 22 can cover the oil leakage hole 16. When the lubricating oil gradually accumulates to a certain height at the bottom of the connecting channel 19, the buoyancy of the oil will push the sealing section 22 upward, thereby opening the oil leakage hole 16 and realizing the discharge of lubricating oil. As the oil level drops, the buoyancy decreases, the valve body moves downward, and the sealing section covers the oil leakage hole 16 again, achieving a sealing effect and preventing excessive oil leakage.

[0070] The valve body sealing section 22 effectively covers the oil leakage hole 16, ensuring proper discharge of lubricating oil and maintaining the oil-gas separation effect within the system. The floating design of the valve body structure 2 allows it to automatically adjust according to oil level changes, reducing the need for manual operation and improving the automation level of the system. The valve body is made of lightweight materials (such as plastic), which reduces its weight, enhances buoyancy, resists corrosion, and extends its service life. The structural design is simple and easy to implement, allowing for convenient replacement or adjustment of the valve body shape to adapt to different working environments and needs. Through an effective oil-gas separation and automatic discharge mechanism, the working efficiency of the entire refrigeration system is optimized, reducing performance loss caused by oil-gas mixing.

[0071] In summary, through innovative design and material selection, the valve body structure 2 achieves efficient automatic discharge of lubricating oil, thereby improving the overall performance and reliability of the system.

[0072] In one embodiment, please refer to Figure 6 and Figure 7 The aforementioned oil-gas separation silencing assembly also includes a silencing chamber cover 4, which covers the first silencing chamber 121 and the second silencing chamber 122.

[0073] In one embodiment, please refer to Figure 8The aforementioned oil-gas separation silencing assembly also includes a sealing gasket 3, which is located between the silencing chamber cover 4 and the cylinder seat exhaust structure 1.

[0074] In this embodiment, the sealing gasket 3 includes three parts: a first silencing cavity sealing section 31, a second silencing cavity sealing section 32, and a sliding groove sealing section 33; the silencing cavity cover 4 includes a first silencing cavity cover 41, a second silencing cavity cover 42, a sliding groove cover 43, a second screw hole 44, and an exhaust hole 45.

[0075] During assembly, the sealing gasket 3 is placed above the cylinder block exhaust structure 1, and the muffler cover 4 covers the sealing gasket 3. At this time, the first muffler sealing section 31 is connected to the first muffler 121, the second muffler sealing section 32 corresponds to the second muffler 122, and the sliding groove sealing section 33 matches the sliding groove 15.

[0076] Subsequently, screw 5 is fastened through the second screw hole 44 on the muffler cover to the first screw hole 18 at the bottom of the first muffler chamber 121 and the second muffler chamber 122 to ensure the stability of the oil-gas separation muffler assembly and maintain airtightness during the compressor's exhaust process. Furthermore, the exhaust port 45 on the muffler cover is connected to the compressor's exhaust pipe coil, allowing exhaust gas from inside the compressor to flow out to the refrigeration system.

[0077] Please see Figure 9 and Figure 10 This oil-gas separator noise reduction assembly is designed for compressors to optimize the exhaust process and reduce noise. Its working principle is as follows:

[0078] Initial state: When the compressor starts to discharge, there is no lubricating oil inside the first silencer chamber 121 and the second silencer chamber 122, the opening of the connecting port 13 is large, and the airflow is unobstructed.

[0079] Exhaust process: As time goes by, when the compressed gas passes through the first silencer 121 and the second silencer 122, it will interact with the oil baffle 17, causing the oil-gas mixture to impact the contact surface at high speed. Under the action of gravity, the oil droplets are deposited at the oil collection port 14 at the bottom of the first silencer 121 and the second silencer 122 and enter the connecting channel 19.

[0080] Oil level rises: The oil level of lubricating oil in the connecting channel 19 gradually rises, and the buoyancy causes the valve body structure 2 to be lifted, thereby opening the oil leakage hole 16, and the oil droplets flow into the oil pool of the compressor housing with gravity.

[0081] Adjustment of connecting port 13: During this process, the opening degree of connecting port 13 is reduced to ensure that connecting port 13 is not completely blocked. At this time, the cross-sectional area becomes smaller and the expansion ratio increases, thereby further enhancing the noise reduction effect.

[0082] Automatic sealing: As the oil level changes, valve body structure 2 moves downward and eventually seals the oil leakage hole 16 again.

[0083] By optimizing airflow and oil-gas separation, the noise during compressor operation is significantly reduced; the improved oil-gas separation effect reduces the impact of the oil-gas mixture on the refrigeration system and improves the overall operating efficiency; the valve body design allows for automatic adjustment of the oil level while maintaining proper opening of the connection port 13, which helps maintain the stability and performance of the system; effective oil-gas separation reduces the impact on the compressor and refrigeration system and extends the service life of the equipment.

[0084] In summary, this oil-gas separation silencing component not only improves the noise problem of the compressor, but also enhances its performance and durability, providing a better operating experience for refrigeration equipment such as refrigerators.

[0085] The aforementioned oil-gas separation and silencing component comprises a cylinder seat exhaust structure 1 and a valve body structure 2. The cylinder seat exhaust structure 1 is provided with a vent 11, first and second silencing chambers 122, and an oil collection and drainage structure. The first silencing chamber 121 is connected to the second silencing chamber 122, and each is provided with an oil baffle structure to optimize the oil-gas separation effect. The valve body structure 2 is connected to the oil collection and drainage structure to realize automatic oil level adjustment, improve silencing and separation efficiency, improve the silencing effect of the compressor, reduce the amount of lubricating oil discharged, and ensure the high efficiency performance of the refrigeration system.

[0086] In one embodiment, a working method performed by the above-described oil-gas separation silencing component is also provided, comprising:

[0087] When the compressor discharges, the oil-gas mixture passes through the oil-blocking structure in the first silencer 121 and the second silencer 122, which is opposite to the airflow direction. The oil-gas mixture collides with the oil-blocking structure, and the oil droplets flow down from the contact surface under the action of gravity and are deposited by the oil collection and discharge structure.

[0088] When the set amount of oil has been deposited, the oil collection and discharge structure will discharge the oil droplets.

[0089] It should be noted that those skilled in the art can clearly understand that the specific implementation process of the working method of the above-mentioned oil-gas separation silencing component can be referred to the corresponding description in the aforementioned oil-gas separation silencing component embodiment. For the sake of convenience and brevity, it will not be repeated here.

[0090] In one embodiment, a compressor is also provided that includes the aforementioned oil-gas separation and silencing assembly. Specifically, the exhaust port 45 on the silencing cover is connected to the compressor's exhaust pipe coil. The silencing assembly effectively reduces noise generated during exhaust, improving the user experience; the optimized oil-gas separation process reduces the impact on compressor performance, improving cooling effect and energy efficiency ratio; by storing sufficient lubricating oil in the compressor, wear is reduced and lubrication effect is improved, enhancing the compressor's durability and extending the equipment's service life.

[0091] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
