Description

Technical Field

[0001] The invention relates to the technical field of silencer structures, and in particular to an oil-gas separation silencer component and a working method thereof, and a compressor. Background Art

[0002] During the operation of the refrigerator compressor, lubricating oil will enter the refrigerant gas circuit in a variety of ways. Specifically, part of the lubricating oil is sucked into the refrigerant gas circuit by sputtering or atomization. When the cylinder of the compressor discharges gas, these oil mists will enter the cylinder head with the refrigerant air flow and flow to the exhaust muffler cavity on the cylinder seat through specially designed vents. In this process, most of the oil mist will adhere to the inner wall of the muffler cavity. Due to the effect of gravity, it gradually accumulates at the bottom of the muffler cavity. Over time, the accumulation of this oil mist will reduce the effective volume of the muffler cavity, which will significantly affect the muffler effect and may cause the compressor noise level to increase, which is a negative impact on the user experience.

[0003] At the same time, a small amount of lubricating oil will be discharged from the compressor along with the gas and enter 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 will increase the thermal resistance of the heat exchanger, thereby reducing the heat exchange efficiency, and ultimately affect the performance and energy efficiency of the entire refrigerator. Especially in the context of the increasing popularity of high-efficiency variable frequency compressors, the oil discharge problem has become more prominent and needs to be solved urgently.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0036] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0037] In the prior art, when the refrigerator compressor is running, the lubricating oil enters the refrigerant gas path through sputtering and atomization and is sucked into the cylinder head. As the gas is discharged, the oil mist adheres to the inner wall of the muffler cavity, and gravity causes it to gradually accumulate to the bottom. This accumulation reduces the effective volume of the muffler cavity, which may lead to an increase in noise levels and affect the user experience. At the same time, part of the lubricating oil is discharged with the gas and enters the refrigeration system, and may adhere to the surface of the heat exchanger. Ultimately, this will increase the thermal resistance of the heat exchanger and reduce thermal efficiency, thereby affecting the overall performance and energy efficiency of the refrigerator.

[0038] To this end, an embodiment of the present invention provides an oil-gas separation silencer component and a working method thereof, and a compressor, so as to improve the silencer effect of the compressor, reduce the emission of lubricating oil, and ensure the high efficiency performance of the refrigeration system.

[0039] Specifically, the oil-gas separation silencer assembly includes a cylinder seat exhaust structure 1 and a valve body structure 2, with multiple silencer cavities and oil collecting and draining structures. An oil retaining structure is provided inside the assembly to prevent the backflow of the oil-gas mixture. Through the compressor exhaust, the oil-gas mixture passes through the silencer cavity, and the oil droplets are deposited under the action of gravity and discharged through the oil collecting and draining structure. The assembly is also equipped with a silencer cavity cover 4 and a sealing gasket 3 to improve sealing and efficiency. The overall design is designed to reduce noise and effectively separate oil and gas.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figures 1 to 4 The above-mentioned oil-gas separation silencer assembly includes: a cylinder seat exhaust structure 1 and a valve body structure 2, the cylinder seat exhaust structure 1 is provided with a vent hole 11, a first silencer chamber 121, a second silencer chamber 122 and an oil collecting and draining structure; the vent hole 11 is connected with the first silencer chamber 121, and the second silencer chamber 122 is connected with the first silencer chamber 121; the oil collecting and draining structure is connected with the first silencer chamber 121 and the second silencer chamber 122 respectively; the first silencer chamber 121 and the second silencer chamber 122 are respectively provided with oil retaining structures, and the valve body structure 2 is connected with the oil collecting and draining structure.

[0042] In this embodiment, when the compressor is exhausted, the oil-gas mixture enters the first muffler chamber 121 through the vent hole 11; the oil-gas mixture encounters the oil retaining structure in the first muffler chamber 121, and collides, and the oil droplets are deposited downward due to gravity. At the same time, the airflow passes through the second muffler chamber 122 to further reduce the noise; the oil droplets in the first muffler chamber 121 and the second muffler chamber 122 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 to maintain the normal operation of the system.

[0043] The design of the silencer chamber effectively reduces the noise during equipment operation and improves the comfort of the working environment; the oil retaining structure and the oil collecting and draining system work together to efficiently separate the oil-gas mixture and ensure the operating efficiency of the equipment; by effectively separating oil and gas, the pollution of oil to the gas transmission pipeline is reduced, which helps to extend the service life of the equipment; the design structure is reasonable, which is convenient for daily maintenance and overhaul, and improves the reliability of the equipment.

[0044] In one embodiment, see Figure 2 The vent hole 11 is inserted into the first muffler cavity 121 at a certain inclination angle and is tangent to the cylindrical wall and bottom surface of the first muffler cavity 121. The design of this inclination angle is limited by the size of the compressor cylinder head exhaust channel and the cylinder seat. The first muffler cavity 121 and the second muffler cavity 122 are both cylindrical structures.

[0045] When the compressor is running, the oil-gas mixture enters the first silencer chamber 121 through the inclined vent hole 11; due to the inclined design of the vent hole 11, the airflow changes when entering the first silencer chamber 121, thereby enhancing the dispersion effect of the airflow and reducing the noise; in the first silencer chamber 121, the oil droplets in the mixture settle downward due to gravity to form 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 air vent 11 design improves the diffusion of air flow, which helps to significantly reduce the noise during equipment operation; the cylindrical cavity design makes the separation of the oil-gas mixture more efficient, ensuring that the oil droplets can be effectively settled.

[0047] In one embodiment, see Figure 1 and Figure 2 The above-mentioned oil-blocking structure includes a plurality of oil-blocking ribs 17 which are arranged obliquely along the direction close to the bottom of the first silencer chamber 121 or the bottom of the second silencer chamber 122. One side of the plurality of oil-blocking ribs 17 is connected to the side wall of the first silencer chamber 121 or the side wall of the second silencer chamber 122, and the plurality of oil-blocking ribs 17 are arranged radially.

[0048] One side of the oil baffle 17 is connected to the cavity wall, which increases the contact area between the oil-gas mixture and the cavity wall; when the oil-gas mixture enters the silencer cavity, the presence of the oil baffle 17 changes the airflow, increases the contact between the oil droplets and the cavity wall, and effectively promotes the sedimentation and separation of the oil droplets; the inclined design of the oil baffle 17 blocks the direct inflow of gas, helps to guide the gas flow, and ensures that the oil droplets can be better collected to prevent them from escaping with the airflow; the protruding 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 the exhaust and can effectively improve the oil blocking effect.

[0049] By increasing the contact area between the oil-gas mixture and the wall of the silencer cavity, the airflow will hit all the contact surfaces in the silencer cavity at high speed. Under the action of gravity, the oil droplets will flow down along the contact surface and settle at the bottom of the silencer cavity. This design achieves a good oil-gas separation effect, significantly reduces the oil content in the gas discharged from the silencer cavity, and thus reduces the impact of oil on the refrigerator refrigeration system.

[0050] The optimized airflow path reduces the noise caused by gas flow and improves the overall silent operation of the equipment. The reasonable design of the oil retaining rib 17 avoids excessive exhaust resistance, ensuring smooth exhaust while the equipment operates efficiently. The effective oil-gas separation reduces the erosion of oil on the refrigeration system, thereby helping to extend the service life of the equipment. The simple design makes system maintenance more convenient and reduces maintenance costs.

[0051] In other embodiments, the plurality of oil-blocking ribs 17 are in a spirally inclined form, or may be in other shapes, and the arrangement must be opposite to the airflow and can increase the inner wall surface of the silencer cavity.

[0052] In one embodiment, see Figure 3 The cylinder seat exhaust structure 1 is also provided with a communication port 13 , and the first muffler chamber 121 is connected with the second muffler chamber 122 through the communication port 13 .

[0053] The exhaust gas from the compressor enters the first muffler chamber 121 through the vent hole 11 and enters the second muffler chamber 122 through the connecting port 13. Since the cross-sectional areas of the channels are different during this exhaust process, the purpose of two-stage expansion muffler can be achieved.

[0054] In one embodiment, see Figures 1 to 4 The above-mentioned oil collecting and draining structure includes an oil collecting port 14, a connecting passage 19, a chute 15 and an oil leakage hole 16; the bottom of the first muffler chamber 121 and the bottom of the second muffler chamber 122 are respectively provided with an oil collecting port 14, and the bottoms of the two oil collecting ports 14 are respectively connected to the connecting passage 19; the chute 15 is placed in the cylinder seat exhaust structure 1, and the chute 15 is connected to the connecting passage 19, the valve body structure 2 is placed in the chute 15, the oil leakage hole 16 is located at the bottom of the connecting passage 19, and the chute 15 is vertically connected to the connecting port 13. Therefore, the up and down movement of the valve body structure 2 built in the chute 15 can adjust the opening degree of the connecting port 13.

[0055] Specifically, the oil collecting port 14 of the first silencer chamber 121 and the oil collecting port 14 of the second silencer chamber 122 are symmetrically arranged at the bottom of the first silencer chamber 121 and the second silencer chamber 122, which are inclined downward and close to the connecting port 13. The oil collecting port 14 of the first silencer chamber 121 and the oil collecting port 14 of the second silencer chamber 122 are the above-mentioned oil collecting ports 14, and the two oil collecting ports 14 are connected at the bottom and communicate with the slide groove 15.

[0056] In the present embodiment, the oil collecting port 14 is arranged to be inclined downward so that the oil droplets can flow from the oil collecting port 14 into the communication channel 19 .

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

[0058] First screw holes 18 are respectively provided at the middle positions of the bottoms of the first silencing chamber 121 and the second silencing chamber 122 .

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

[0060] In this embodiment, in the first silencer chamber 121 and the second silencer chamber 122, the oil-gas mixture hits the wall at high speed, promoting the separation of oil droplets and gas. The deposited lubricating oil will gather at the bottom of the first silencer chamber 121 and the second silencer chamber 122, and flow into the connecting channel 19 from the oil collecting port 14. When the lubricating oil in the connecting channel 19 is deposited to a certain amount, the valve body structure 2 will move upward along the axis due to the buoyancy. The rise of the valve body structure 2 opens the oil leakage hole 16 at the bottom, and the lubricating oil begins to drip out of the oil leakage hole 16 until the oil level drops to the lower limit position of the valve body structure 2, and the valve body structure 2 moves down accordingly, and finally seals the oil leakage hole 16. This cycle process enables the system to effectively discharge excess lubricating oil while maintaining the normal operation of the silencer chamber.

[0061] By increasing the contact area and gravity, the oil and gas can be effectively separated, the separation efficiency can be improved, and the oil content in the compressor exhaust can be reduced; the floating design of the valve body structure 2 makes the discharge process of the lubricating oil automatic without manual intervention, which improves the reliability and ease of operation of the system;

[0062] Reducing the oil content in the compressor exhaust helps to protect the refrigerator refrigeration system and reduce the impact of oil on the refrigeration effect, thereby improving the refrigeration efficiency and system life; the arc design of the connecting channel 19 and the setting of the slide groove 15 make the oil and gas separation and discharge process smoother, ensuring the overall performance and stability of the system.

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

[0064] In one embodiment, see Figure 5 The valve body structure 2 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 main section 21 of the valve body is matched with the inner wall surface of the slide groove 15 with a very small gap, 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 effect of sealing the cavity, but it cannot completely overlap with the top of the oil leakage hole 16, otherwise it cannot move up under the action of buoyancy.

[0066] In one embodiment, the valve body structure 2 is a plastic part, the valve body main 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 in other shapes, which need to be changed synchronously 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 is composed of a valve body main section 21 and a valve body sealing section 22. A small gap is maintained between the main section and the inner wall of the slide groove 15 to allow axial displacement. The valve body sealing section 22 can cover the oil leakage hole 16 when it is in a suitable position; 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 valve body sealing section 22 up, thereby opening the oil leakage hole 16 and achieving the discharge of the lubricating oil; as the oil level drops, the buoyancy decreases, the valve body moves down accordingly, and the sealing section covers the oil leakage hole 16 again, achieving a sealing effect to prevent excessive oil from flowing out.

[0070] The valve body sealing section 22 can effectively cover the oil leakage hole 16, ensure the proper discharge of lubricating oil, and maintain the oil-gas separation effect in the system; the floating design of the valve body structure 2 allows it to automatically adjust according to the oil level changes, reducing the need for manual operation and improving the degree of automation of the system; the use of lightweight materials (such as plastic) to manufacture the valve body can not only reduce the weight of the valve body and enhance the buoyancy effect, but also resist corrosion and extend the service life; the structural design is simple and easy to implement, and the shape of the valve body can be easily replaced or adjusted to adapt to different working environments and needs; through effective oil-gas separation and automatic discharge mechanism, the working efficiency of the entire refrigeration system is optimized and the performance loss caused by oil-gas mixing is reduced.

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

[0072] In one embodiment, see Figure 6 and Figure 7 The above-mentioned oil-gas separation silencer assembly also includes a silencer chamber cover 4 , which seals the first silencer chamber 121 and the second silencer chamber 122 .

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

[0074] In this embodiment, the sealing gasket 3 includes three parts: a first silencer chamber sealing section 31, a second silencer chamber sealing section 32 and a slide groove sealing section 33; the silencer chamber cover 4 includes a first silencer chamber cover 41, a second silencer chamber cover 42, a slide 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 seat exhaust structure 1, and the muffler chamber cover 4 covers the sealing gasket 3. At this time, the first muffler chamber sealing section 31 is connected to the first muffler chamber 121, the second muffler chamber sealing section 32 corresponds to the second muffler chamber 122, and the slide groove sealing section 33 matches the slide groove 15.

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

[0077] See also Fig. 9 and Fig.10 , this oil-gas separation silencer component 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 exhaust, there is no lubricating oil inside the first muffler chamber 121 and the second muffler chamber 122, the opening of the connecting port 13 is relatively large, and the airflow is unobstructed.

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

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

[0081] Adjustment of the connecting port 13: In this process, the opening degree of the connecting port 13 is reduced to ensure that the 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 silencing effect.

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

[0083] By optimizing the 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 design of the valve body allows automatic adjustment of the oil level while keeping the connecting port 13 properly open, which helps to 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, the oil-gas separation silencer assembly 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 above-mentioned oil-gas separation silencer component is provided with a cylinder seat exhaust structure 1 and a valve body structure 2. The cylinder seat exhaust structure 1 is provided with an air vent 11, a first and a second silencer chamber 122, and an oil collecting and draining structure. The first silencer chamber 121 is connected to the second silencer chamber 122, and each is provided with an oil retaining structure to optimize the oil-gas separation effect. The valve body structure 2 is connected to the oil collecting and draining structure to realize automatic adjustment of the oil level, improve the silencer and separation efficiency, improve the silencer effect of the compressor, reduce the discharge of lubricating oil, and ensure the high efficiency performance of the refrigeration system.

[0086] In one embodiment, a working method performed by the above-mentioned oil-gas separation silencer assembly is also provided, comprising:

[0087] The compressor exhausts, and the oil-gas mixture passes through the oil retaining structure in the first muffler chamber 121 and the second muffler chamber 122 in the opposite direction of the airflow, so that the oil-gas mixture collides with the oil retaining structure, and the oil droplets flow down from the contact surface under the action of gravity, and are deposited by the oil collecting and draining structure;

[0088] When the oil is deposited to a set amount, the oil collecting and draining structure discharges the oil droplets.

[0089] It should be noted that technical personnel in the relevant field can clearly understand that the specific implementation process of the working method performed by the above-mentioned oil-gas separation silencer component can refer to the corresponding description in the aforementioned oil-gas separation silencer component embodiment, and for the convenience and conciseness of the description, it will not be repeated here.

[0090] In one embodiment, a compressor is also provided, which includes the above-mentioned oil-gas separation silencer assembly. Specifically, the exhaust hole 45 on the silencer cover is connected to the exhaust pipe coil of the compressor. The silencer assembly effectively reduces the noise generated during exhaust, improving the user experience; the optimized oil-gas separation process reduces the impact on the performance of the compressor, improves the refrigeration effect and energy efficiency ratio; by storing sufficient lubricating oil in the compressor, wear is reduced and the lubrication effect is improved, the durability of the compressor is enhanced, and the service life of the equipment is extended.

Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
