Description

Technical Field

[0001] This invention relates to the field of air conditioner technology, specifically providing a silencer oil separator, a compressor, and an air conditioner. Background Technology

[0002] When an air conditioner is running, the compressor's pump assembly compresses the refrigerant and discharges the gaseous refrigerant. During the discharge of the gaseous refrigerant, the oil inside the compressor is discharged along with the refrigerant gas, resulting in oil loss and affecting compressor lubrication.

The separated oil is then directed to components such as bearings for lubrication. Existing oil separators primarily rely on centrifugal force and filter screens for oil separation, resulting in less than ideal separation efficiency.

[0081] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0082] It should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0083] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "connection," "setup," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0084] First refer to Figures 1 to 4The silencer oil separator of the present invention will be described. Figure 1 This is a cross-sectional schematic diagram of the silencer oil separator of the present invention; Figure 2 This is a schematic diagram of the oil separator of the present invention. Figure 1 ; Figure 3 This is a schematic diagram of the oil separator of the present invention. Figure 2 ; Figure 4 This is a schematic diagram of the silencer sleeve of the present invention.

[0085] like Figures 1 to 4 As shown, in order to solve the problems of poor oil separation effect and high exhaust noise of existing oil separators, the silencer oil separator of this application includes an oil separator box 10 and a filler 20. The oil separator box 10 has an oil separation chamber 101 and a first air inlet 102 and a first air outlet 103 respectively provided on the oil separator box 10. The first air inlet 102 and the first air outlet 103 are both connected to the oil separation chamber 101. The oil separator box 10 is also provided with an oil return channel 104, which is connected to the oil separation chamber 101. The filler 20 is provided in the oil separation chamber 101 and can separate the oil in the exhaust gas flow entering the oil separation chamber 101.

[0086] This application incorporates a filler 20 within the oil separator chamber 101. This filler 20 filters the exhaust gas flow upon entry into the chamber, separating the oil mixed within it and improving separation efficiency. Furthermore, the filler 20 buffers the exhaust gas flow as it enters the chamber, reducing its impact on the inner wall and minimizing exhaust pulsation, thus lowering exhaust noise. Simultaneously, the flow of exhaust gas through the filler 20 generates some kinetic energy, reducing its velocity and further minimizing pulsation. This dual vibration reduction further lowers the exhaust noise of the oil separator.

[0087] The following is further reference Figures 1 to 4 This paper describes a preferred embodiment of the silencer oil separator of this application. Those skilled in the art will understand that the embodiments described below are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Provided that the silencer oil separator includes at least an oil separator box 10 and a filler 20, those skilled in the art can adjust the following configuration to make this application applicable to more specific application scenarios.

[0088] See Figure 2The muffler oil separator includes an oil separator box 10 and filler material 20. The oil separator box 10 has a connection hole 106. The oil separator box 10 has an oil separator chamber 101 arranged around the connection hole 106, and the oil separator chamber 101 has an annular chamber structure. The outer wall of the oil separator chamber 101 has a first air inlet 102 and a first air outlet 103, both of which communicate with the oil separator chamber 101. The bottom of the oil separator box 101 is circumferentially surrounded by an oil return channel 104, which is an annular groove and communicates with the oil separator chamber 101. The filler material 20 is disposed inside the oil separator chamber 101, wherein the filler material 20 is filler particles.

[0089] By providing filler 20 within the oil separator chamber 101, firstly, the exhaust airflow can be filtered by the filler 20, separating the oil mixed in the exhaust airflow and improving oil separation efficiency; secondly, the filler 20 can also buffer the exhaust airflow, reducing the impact of the exhaust airflow on the inner wall of the oil separator chamber 101; thirdly, when the exhaust airflow flows through the filler 20, it generates a certain amount of kinetic energy, reducing the flow velocity of the exhaust airflow, thereby reducing exhaust pulsation and lowering the exhaust noise of the oil separator. When the filler 20 is composed of filler particles, the friction between the filler particles can also be used to separate the oil mixed in the exhaust airflow, further improving oil separation efficiency.

[0090] It should be noted that the specific form of the filler 20 is not fixed in this application, and those skilled in the art can adjust it flexibly according to the actual situation. For example, the filler 20 can also be a sponge-like filler material.

[0091] Furthermore, this application does not limit the material of the filler 20, and those skilled in the art can adjust it flexibly according to the actual situation. For example, the material of the filler 20 can be a metallic material such as steel or copper, or a non-metallic material such as mica or ceramics.

[0092] See Figure 2 The oil distribution chamber 101 is also equipped with multiple partitions 30, which are spaced apart circumferentially along the oil distribution chamber 101, dividing the oil distribution chamber 101 into multiple sub-chambers. Each sub-chamber is equipped with a filler 20 (for easier display of other components, ...). Figure 2 (The filler 20 is not shown in the diagram), and each sub-chamber is directly connected to the oil return channel 104. The first air inlet 102 and the first air outlet 103 are located on the outer wall of the same sub-chamber and are both connected to it, allowing the exhaust gas flow to circulate around the oil separation chamber 101, extending the flow path of the exhaust gas flow, maximizing the separation of oil mixed in the exhaust gas flow, and improving the oil separation rate. Each partition 30 is provided with a vent 301, and adjacent sub-chambers are interconnected through the vent 301. One of two adjacent vents 301 is located at the top of the partition (e.g., at the top of the partition). Figure 2 One is located at the top of the partition 30, and the other is located at the bottom of the partition 30 (e.g., above the partition). Figure 2 The lower part of the vent hole 301 is arranged at different heights in the axial direction to extend the flow path of the exhaust airflow. On the one hand, this can increase the energy consumption of the exhaust airflow, reduce exhaust pulsation, and reduce noise; on the other hand, it can also maximize the separation of oil mixed in the exhaust airflow and improve the oil separation rate.

[0093] Of course, in this embodiment, the location of the vent 301 is not fixed and can be flexibly adjusted by those skilled in the art according to the actual product situation. For example, the distance from the center of adjacent vents 301 to the center of the connecting hole 106 is different, which can also extend the flow path of the exhaust airflow.

[0094] In an exemplary embodiment, the partition 30 may also be positioned axially along the oil distribution chamber 101. Specifically, as shown... Figure 3 As shown, multiple baffles 30 are spaced apart along the axial direction of the oil distribution chamber 101. The baffles 30 can divide the oil distribution chamber 101 into multiple sub-chambers, and each sub-chamber is provided with a filler 20 (for easier display of other components, ...). Figure 3 (The filler 20 is not shown in the image). The first air inlet 102 is located at the bottom (e.g., ...). Figure 3 The first vent 103 is located on the outer wall of the sub-chamber (below) and communicates with the sub-chamber; the first vent 103 is located at the top (e.g., the lower part of the chamber). Figure 3 The partition plate 30 is located on the outer wall of the sub-chamber (above) and communicates with the sub-chamber. This arrangement extends the flow path of the exhaust gas, maximizing the separation of oil mixed in the exhaust gas and improving the oil separation rate. Each partition plate 30 is provided with a vent 301, and adjacent sub-chambers communicate with each other through the vent 301. One of two adjacent vent 301s is located at the leftmost end of the partition plate 30 (e.g., at the top). Figure 3 One is located at the left end of the partition 30, and the other is located at the rightmost end of the partition 30 (e.g., the left end of the partition 30). Figure 3 The right end of the ventilation holes 301 is arranged so that the projections of adjacent ventilation holes 301 in the axial direction do not overlap, thereby extending the flow path of the exhaust airflow. This increases the energy consumption of the exhaust airflow, reduces exhaust pulsation, and reduces noise; it also maximizes the separation of oil mixed in the exhaust airflow, improving the oil separation rate. In this embodiment, the lowermost sub-chamber is directly connected to the return oil channel 104, while the remaining sub-chambers (i.e., all sub-chambers except the lowermost one) are indirectly connected to the return oil channel 104 through ventilation holes 301. The oil separated from the remaining sub-chambers flows sequentially from the ventilation holes 301 into the lower sub-chambers until it flows into the return oil channel 104. The oil separation effect in this embodiment is worse than that in the above embodiment.

[0095] Of course, in this embodiment, the location of the vent 301 is not fixed and can be flexibly adjusted by those skilled in the art according to the actual product situation. For example, one of two adjacent vents 301 can be located at the leftmost end of the partition 30, and the other can be located in the middle of the partition 30.

[0096] Although, Figure 2 The diagram shows six baffles 30 spaced circumferentially within the oil distribution chamber 101. Figure 3 The illustration shows two baffles 30 axially spaced within the oil distribution chamber 101. However, this is merely exemplary and not restrictive. Those skilled in the art can flexibly adjust the number of baffles 30 according to the actual product. For example, three, four, or other numbers of baffles 30 may be axially spaced within the oil distribution chamber 101.

[0097] It should be noted that the positions of the first air inlet 102 and the first air outlet 103 are not fixed in this application, and those skilled in the art can adjust them flexibly according to the actual situation. For example, the first air inlet 102 can also be set at the bottom, top, or other positions of the oil separator 10, and / or the first air outlet 103 can also be set at the bottom, top, or other positions of the oil separator 10.

[0098] See Figure 1 and Figure 4 The muffler also includes a muffler sleeve 40, which has a muffler cavity 401. A second air inlet 402 is located at the bottom of the muffler sleeve 40, and a second air outlet 403 is located on the side wall of the muffler sleeve 40. The second air inlet 402 and the second air outlet 403 are respectively connected to the muffler cavity 401. The inner diameter of the muffler sleeve 40 gradually increases along the axial exhaust direction, which reduces the impact of the exhaust airflow on the inner wall of the muffler cavity 401, reduces exhaust pulsation, and thus reduces exhaust noise. The oil separator box 10 is disposed inside the muffler cavity 401, and both the first air inlet 102 and the first air outlet 103 are connected to the muffler cavity 401.

[0099] Of course, the positions of the second air inlet 402 and the second air outlet 403 are not fixed in this application, and those skilled in the art can adjust them flexibly according to the actual situation. For example, the second air inlet 402 can also be located on the side wall or top of the muffler sleeve 40; and / or, the second air outlet 403 can also be located on the bottom or top of the muffler sleeve 40. In addition, it is worth mentioning that when the second air outlet 403 is located on the side wall or bottom of the muffler sleeve 40, it can prevent the exhaust airflow from directly impacting the compressor cover and causing vibration, thereby reducing the operating noise of the compressor.

[0100] In addition, this application also discloses a compressor, which includes a flange 50 and a silencer oil separator as described in any of the above embodiments. The silencer oil separator is sleeved on the flange 50 through a connection hole 106.

[0101] The following reference Figures 5 to 11 The compressor of the present invention will be described. Wherein, Figure 5 This is a schematic cross-sectional view of the flange and sliding component of the present invention. Figure 1 ; Figure 6 This is a cross-sectional schematic diagram of the slider of the present invention in the first position; Figure 7 This is a cross-sectional schematic diagram of the slider of the present invention in the second position; Figure 8 yes Figure 6 A magnified view of a section at point A in the middle; Figure 9 This is a schematic cross-sectional view of the flange and sliding component of the present invention. Figure 2 ; Figure 10 This is a schematic diagram of the exhaust path of the present invention; Figure 11 This is a cross-sectional schematic diagram of the compressor of the present invention.

[0102] See Figure 5 and Figure 10 The flange 50 is provided with an exhaust channel 501, which includes a first exhaust channel 5011 and a second exhaust channel 5012 that are interconnected. The first exhaust channel 5011 is connected to an exhaust gas source, and the second exhaust channel 5012 is connected to a second air inlet 402. The diameter of the second exhaust channel 5012 is larger than the diameter of the first exhaust channel 5011.

[0103] It is worth mentioning that the exhaust gas source is generated by the compression of gas by roller 120 during compressor operation. Specifically, as... Figure 11 As shown, during the operation of the compressor, the motor 90 drives the crankshaft 110 and the roller 120 to perform circular motion. The roller 120 periodically compresses the gas in the cylinder 130, thereby generating an exhaust gas source.

[0104] See Figures 5 to 7 The compressor also includes a sliding member 60 and an elastic member 70, which are radially disposed within the second exhaust passage 5012. The first end of the elastic member 70 is disposed on the inner wall of the second exhaust passage 5012 (e.g., ...). Figure 5 On the right side wall of the exhaust channel 501, a sliding member 60 is provided at its second end. The sliding member 60 can move between a first position and a second position under the action of the elastic member 70, so that the exhaust channel 501 and the second air inlet 402 are connected or disconnected.

[0105] Specifically, such as Figure 6As shown, when the slider 60 is in the first position, the elastic member 70 is in a compressed state, and the slider 60 no longer blocks the first exhaust passage 5011, thereby opening the first exhaust passage 5011 and connecting the exhaust passage 501 with the second air inlet 402. Figure 7 As shown, when the slider 60 is in the second position, the elastic member 70 is in the natural state, and the slider 60 completely covers the first exhaust channel 5011, thereby closing the first exhaust channel 5011 and disconnecting the exhaust passage 501 from the second air inlet 402.

[0106] It should be noted that the compressor also includes a control component (not shown in the figure), which adjusts the state of the elastic element 70 so that the elastic element 70 can switch between a compressed state and a natural state, thereby driving the sliding element 60 to move between a first position and a second position.

[0107] Of course, the type of elastic element 70 is not fixed in this application, and those skilled in the art can adjust it flexibly according to the actual product situation. For example, elastic element 70 can be a spring.

[0108] It should also be noted that the implementation of the sliding member 60 moving between the first and second positions in this application is not unique, and those skilled in the art can flexibly adjust it according to the actual product situation. For example, a driving member can also be provided to drive the sliding member 60 to move between the first and second positions. Specifically, the driving member is disposed in the second exhaust channel 5012, and the output end of the driving member is provided with the sliding member 60. The sliding member 60 moves between the first and second positions under the driving action of the driving member. When the sliding member 60 is in the first position, the driving member retracts so that the sliding member 60 no longer blocks the first exhaust channel 5011, thereby opening the first exhaust channel 5011 and connecting the exhaust passage 501 with the second air inlet 402; when the sliding member 60 is in the second position, the driving member extends so that the sliding member 60 completely covers the first exhaust channel 5011, thereby closing the first exhaust channel 5011 and disconnecting the exhaust passage 501 from the second air inlet 402. The driving member includes, but is not limited to, a hydraulic drive device, an electric push rod, etc.

[0109] like Figure 6 and Figure 8 As shown, the sliding member 60 is on the side opposite to the elastic member 70 (e.g. Figure 6 The left side of the slide 60 is provided with a buffer protrusion 601, which is a hemispherical protrusion. The buffer protrusion 601 can reduce the speed of the exhaust airflow to a certain extent, reduce the impact of the exhaust airflow on the side wall of the slide 60, and play a certain role in noise reduction.

[0110] See Figures 5 to 7The compressor also includes a buffer pad 80, which is disposed on the inner wall of the second exhaust passage 5012 on the side opposite to the elastic member 70 (e.g., Figure 5 On the left side wall of the first exhaust channel 5011, the sliding member 60 is designed to prevent it from impacting the inner wall of the second exhaust channel 5012 during movement, thus avoiding mechanical noise caused by the impact. The projection of the buffer pad 80 in the axial direction does not coincide with the projection of the first exhaust channel 5011 in the axial direction, preventing air leakage from the compressor during non-exhaust periods.

[0111] Of course, this application does not limit the material of the cushioning pad 80, and those skilled in the art can adjust it flexibly according to the actual product situation. For example, the material of the cushioning pad 80 may be sponge, foam, or rubber, etc.

[0112] In an exemplary embodiment, the sliding member 60, the elastic member 70, and the buffer pad 80 may also be arranged axially within the second exhaust channel 5012. For example... Figure 9 As shown, the first end of the elastic element 70 is disposed on the inner wall of the second exhaust channel 5012 (e.g., Figure 9 On the upper sidewall of the second vent 5012, a sliding member 60 is provided at its second end, and a buffer pad 80 is provided on the inner wall of the second vent 5012 on the side opposite to the elastic member 70 (e.g., Figure 9 The second exhaust channel 5012 includes an upper channel and a lower channel that are interconnected. The upper channel is connected to the second air inlet 402, and the lower channel is connected to the first exhaust channel 5011. The diameter of the upper channel is larger than that of the lower channel. In this embodiment, the radial dimension of the sliding member 60 is smaller than the diameter of the upper channel, allowing the exhaust airflow to pass smoothly. The sliding member 60 can completely cover the first exhaust channel 5012, preventing air leakage from the compressor during non-exhaust periods. When the elastic member 70 is in a compressed state, the radial projection of the sliding member 60 does not coincide with the radial projection of the lower channel, so that during exhaust, the sliding member 60 can avoid contact with the lower channel, allowing the exhaust airflow to pass smoothly.

[0113] Specifically, when the slider 60 is in the first position, the elastic member 70 is in a compressed state, the slider 60 no longer blocks the first exhaust channel 5011, and the slider 60 is offset from contact with the lower channel, thereby opening the lower channel and connecting the exhaust channel 501 with the second intake port 402, allowing the exhaust airflow to pass smoothly through the exhaust channel 501. When the slider 60 is in the second position (e.g. Figure 9 As shown, the elastic member 70 is in its natural state, and the sliding member 60 completely covers the first exhaust channel 5011, so that the exhaust channel 501 is disconnected from the second air inlet 402.

[0114] In an alternative embodiment, the slider 60, elastic element 70, and buffer pad 80 may also be disposed in the first exhaust channel 5011. When the diameter of the first exhaust channel 5011 is larger than the diameter of the second exhaust channel 5012, the slider 60, elastic element 70, and buffer pad 80 may be disposed radially within the first exhaust channel 5011. The first end of the elastic element 70 is disposed on the inner wall of the first exhaust channel 5011, and the second end is provided with the slider 60. The buffer pad 80 is disposed on the inner wall of the first exhaust channel 5011 on the side opposite to the elastic element 70. The slider 60 can move between a first position and a second position under the action of the elastic element 70, thereby connecting or disconnecting the exhaust channel 501 from the second air inlet 402. In this embodiment, the slider 60, elastic element 70, and buffer pad 80 have all the technical effects of the preferred embodiment described above, and will not be repeated here.

[0115] Reference Figure 2 , Figure 5 , Figure 10 and Figure 11 The bottom of the oil separator 10 is also provided with an oil return hole 105, which is connected to the oil return channel 104. The flange 50 is provided with an oil guide channel 502, which is connected to the oil return channel 104 through the oil return hole 105. The oil separated from the exhaust airflow in the oil separator 10 first flows into the oil return channel 104. The oil collected in the oil return channel 104 can flow into the oil guide channel 502 through the oil return hole 105. The oil in the oil guide channel 502 can flow to the crankshaft 110 and flow along the outer circumference of the crankshaft 110, thereby lubricating the components installed on the crankshaft 110.

[0116] The following reference Figure 10 and Figure 11 The exhaust path and oil return path of the compressor in this application are described.

[0117] Exhaust path: First, the exhaust airflow from the exhaust gas source enters the first exhaust channel 5011. When the sliding member 60 is in the first position, the exhaust airflow can pass through the second exhaust channel 5012 and the second air inlet 402 in sequence and enter the muffler 401. Next, the exhaust airflow enters the oil distribution chamber 101 through the first air inlet 102. After entering the oil distribution chamber 101, the exhaust airflow flows through multiple sub-chambers in sequence, and then exits the oil distribution chamber 101 through the first air outlet 103 and re-enters the muffler 401. After that, the exhaust airflow enters the compressor inner cavity 140 through the second air outlet 403. Finally, the exhaust airflow exits the compressor through the exhaust port 150 on the upper cover, completing the exhaust process.

[0118] Oil return path: After the exhaust airflow enters the oil distribution chamber 101, the oil mixed therein is separated by the filler 20. The separated oil first flows into the oil return channel 104. Then, the oil collected in the oil return channel 104 flows into the oil guide channel 502 through the oil return hole 105. The oil in the oil guide channel 502 can flow to the crankshaft 110 and flow along the outer periphery of the crankshaft 110, thereby lubricating the components installed on the crankshaft 110.
