Description

Technical Field

[0001] This utility model relates to the field of scroll compressors, and in particular, to a suction baffle structure for a scroll compressor. Background Technology

[0002] The content in this section provides only background information related to this disclosure and may not constitute prior art.

[0003] A suction baffle structure is installed at the suction port of a scroll compressor to divert and guide the gas entering the compressor. However, in related scroll compressor suction baffle structures, problems exist such as ineffective and uneven motor cooling, potentially excessively high oil circulation rates, and significant upward leakage of gas from the suction baffle structure.

[0004] Figures 1-4 Exemplary suction baffle structures for scroll compressors based on related technologies are shown below. These suction baffle structures are all positioned at the suction port of the scroll compressor to divert and guide the gas entering the compressor through the suction port. The following will refer to... Figure 1 and Figure 4 These exemplary intake baffle structures are described.

[0005] Figure 1 A first exemplary intake baffle structure 101 is shown, which includes an intake baffle 102 having a partition 103 at its top for blocking upward flow of gas entering the compressor, causing most of the intake gas to flow downward. The problem with this intake baffle structure is that it still cannot effectively prevent intake gas from leaking upward from the intake baffle structure, and it is essentially unable to guide the gas to uniformly cool the motor (especially with limited cooling of the upper portion of the motor).

[0006] Figure 2 A second exemplary intake baffle structure 201 is shown, which includes an intake baffle 202 having a partition 203 located in the middle of the intake baffle 202. The partition 203 is used to split the gas entering the compressor, wherein a portion of the gas flows upward and another portion flows downward. The problem with this intake baffle structure is that it cannot prevent intake gas from leaking upward from the intake baffle structure, thus failing to effectively cool the motor, and also resulting in poor cooling of the upper part of the motor.

[0007] Figure 3A third exemplary intake baffle structure 301 is shown, which includes an intake baffle 302, wherein the intake baffle 302 has a partition 303 located at the bottom of the intake baffle 302, the partition 303 for blocking the downward flow of gas entering the compressor, causing most of the intake gas to flow upward. The problem with this intake baffle structure is that it cannot completely prevent the intake gas from leaking upward from the intake baffle structure, thus failing to effectively cool the motor.

[0008] Figure 4 A fourth exemplary intake baffle structure 401 is shown, which includes an intake baffle 402 and an annular mounting portion 404 connected to the intake baffle 402. The intake baffle 402 has a partition 403 located in the lower center of the intake baffle 402 and an opening in its lower portion. An opening is also provided on the inner wall of the annular mounting portion 404 at a position corresponding to the opening in the intake baffle 402, allowing intake gas to enter the annular mounting portion 404 through the lower opening of the intake baffle 402 and the opening of the annular mounting portion 404, and flow downwards through multiple gaps in the bottom wall of the annular mounting portion 404 to cool the motor. The problem with this intake baffle structure is that it cannot prevent intake gas from leaking upwards from the intake baffle structure, resulting in poor cooling of the motor, especially the lower part of the motor.

[0009] Therefore, there is a need for an improved intake baffle structure for a scroll compressor that can properly divert the intake gas, thereby effectively reducing the upward leakage of the intake gas and thus effectively cooling the motor. Utility Model Content

[0010] This section provides a general summary of the present invention, rather than a full disclosure of the complete scope or all features of the present invention.

[0011] The main objective of this invention is to solve or alleviate one or more of the technical problems mentioned above. For example, the suction baffle structure of the scroll compressor according to this invention has multiple baffles to effectively reduce the amount of gas leaking upwards, thereby enabling a sufficient amount of suction gas to adequately cool the motor of the scroll compressor, achieving an effective cooling effect on the motor.

[0012] To address one or more of the aforementioned technical problems, according to one aspect of this utility model, an intake baffle structure is provided for use in a scroll compressor. The scroll compressor has an intake port and a compression mechanism. Gas from outside the scroll compressor can enter the interior of the scroll compressor through the intake port and then enter the compression mechanism for compression. The intake baffle structure is installed on the scroll compressor to guide and divert the gas entering the interior of the scroll compressor. The intake baffle structure includes a first partition and a second partition disposed near the top of the intake port. The first partition and the second partition are arranged sequentially in the vertical direction. The first partition and the second partition cooperate to block the upward flow path of the gas entering the interior of the scroll compressor through the intake port.

[0013] In the above-described intake baffle structure, the shape of the top portion of the first baffle and / or the second baffle is configured to conform to the shape of the top portion of the intake port.

[0014] In the above-mentioned suction baffle structure, the suction baffle structure includes a suction baffle for being disposed inside the scroll compressor. The suction baffle includes a body part having a suction surface for facing the suction port of the scroll compressor. A first baffle and a second baffle are disposed on the suction surface.

[0015] In the above-mentioned air intake baffle structure, the second baffle is arranged vertically below the first baffle. The second baffle is arched, and the shape of the top part of the second baffle is configured to match the shape of the corresponding part of the air intake.

[0016] In the above-mentioned intake baffle structure, an exhaust window is also provided in the main body, and the exhaust window is positioned below the second partition in the vertical direction.

[0017] In the above-described intake baffle structure, the intake surface includes a windward surface located in the vertical direction between the second partition and the exhaust window. The windward surface is configured to be inclined relative to the rest of the intake surface of the main body portion to guide the gas entering the intake baffle structure toward the exhaust window.

[0018] In the above-mentioned suction baffle structure, the suction baffle structure also includes a third baffle for being disposed near the top of the suction port. The third baffle is disposed on the suction surface, and the third baffle, the first baffle, and the second baffle are arranged sequentially in the vertical direction.

[0019] In the above-described suction baffle structure, the suction baffle structure includes a suction baffle for being disposed inside the scroll compressor. The suction baffle includes a body portion having a suction surface for facing the suction port of the scroll compressor. A first partition is disposed on the suction surface. The suction baffle structure also includes a tubular member for being nested in the suction port of the scroll compressor. The proximal end of the tubular member is for extending toward the suction baffle and entering the interior of the scroll compressor, thereby forming a second partition.

[0020] In the above-mentioned intake baffle structure, the plane where the opening at the proximal end of the tubular member is located is obliquely intersecting the longitudinal axis of the tubular member, such that the top longitudinal length of the portion of the tubular member extending into the interior of the scroll compressor is greater than the bottom longitudinal length; or the planes where the openings at the proximal end and the distal end opposite to the proximal end of the tubular member are located are both perpendicular to the longitudinal axis of the tubular member, such that the top longitudinal length of the tubular member is equal to the bottom longitudinal length of the tubular member.

[0021] In the above-described suction baffle structure, the suction baffle structure further includes an annular mounting portion, which is connected to the mounting surface of the body portion of the suction baffle that is opposite to the suction surface. The annular mounting portion is configured to be fixedly connected to the main bearing housing of the scroll compressor for mounting the suction baffle structure in the scroll compressor.

[0022] In the above-mentioned intake baffle structure, a baffle is provided on the bottom surface of the annular mounting part, so that the gas flowing along the annular mounting part can form a vortex at the baffle.

[0023] According to another aspect of the present invention, a scroll compressor is also provided, wherein the scroll compressor includes the suction baffle structure as described above.

[0024] The advantages of the suction baffle structure of this utility model are as follows: The suction baffle structure has multiple baffles for being set near the top of the suction port of the scroll compressor. Therefore, it can effectively block the upward flow path of the gas entering the interior of the scroll compressor and effectively reduce the amount of gas that directly leaks upward into the scroll compressor. This improves the utilization rate of the gas for cooling the motor of the scroll compressor, thereby ensuring that a sufficient amount of suction gas flows downward to fully cool the motor, so as to achieve the effect of effectively cooling the motor. Furthermore, according to this utility model, by optimizing the intake baffle structure, specifically, in addition to having a downward-opening gas channel to guide the gas to the motor (especially the lower part of the motor), the intake baffle structure also has an exhaust window for guiding the gas to the annular mounting part of the intake baffle structure and then to the motor (especially the upper part of the motor), so that the motor can be cooled evenly (i.e., both the upper and lower parts of the motor are properly cooled), and the amount of lubricating oil flowing into the compression mechanism can be appropriately controlled through this appropriate diversion (the flow ratio of the gas entering the intake baffle structure via the lower gas channel and the middle exhaust window), thereby achieving the desired oil circulation rate.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. This detailed description is for illustrative purposes only and is not intended to limit the invention or its applications or uses.

[0046] This invention provides an intake baffle structure for a scroll compressor. The intake baffle structure has multiple baffles disposed near the top of the intake port of the scroll compressor to effectively reduce the upward leakage of intake gas, improve the utilization rate of gas for cooling the motor, and ensure that a sufficient amount of intake gas flows downward to fully cool the motor, thereby achieving an effective cooling effect on the motor.

[0047] First, refer to Figures 5-9 The overall structure and working principle of the suction baffle structure for a scroll compressor according to the first embodiment of the present invention are briefly described.

[0048] Figure 5 This is a perspective view of the intake baffle structure according to the first embodiment of the present invention. Figure 6 This is a front view of the suction baffle structure according to the first embodiment of the present invention, wherein the portion of the suction baffle structure facing the suction port of the scroll compressor is shown. Figure 7 This is a side view of the intake baffle structure according to the first embodiment of the present invention. Figure 8 This is a bottom view of the intake baffle structure according to the first embodiment of this utility model. See below for reference. Figures 5-8 The air intake baffle structure according to the first embodiment of the present invention is described.

[0049] like Figures 5-8As shown, the suction baffle structure 10 according to the first embodiment includes a suction baffle 11 and an annular mounting portion 12. The suction baffle 11 includes a flat, plate-shaped body portion 111 and two side portions located on two sides of the body portion 111 that protrude from the body portion 111 in a direction opposite to the annular mounting portion 12. Thus, the suction baffle structure 10 has a downwardly opening gas passage, allowing most or a portion of the gas entering the suction baffle structure to flow downward out of the suction baffle structure and cool the motor (especially the lower part of the motor). The body portion 111 includes a suction surface 112 for facing the suction port of the scroll compressor and a mounting surface 113 opposite to the suction surface 112. The annular mounting portion 12 is integrally connected to the mounting surface 113 of the body portion 111. The annular mounting portion 12 is provided with a threaded hole and can be bolted to the main bearing housing of the scroll compressor for mounting the suction baffle structure 10 in the scroll compressor. The intake baffle structure 10 also includes a first partition 114 disposed on the intake surface 112 and located at the top of the body portion 111. The first partition 114 can protrude from the intake surface 112 in a direction perpendicular to the intake surface 112 and extends between two side portions of the intake baffle 11. The intake baffle structure 10 also includes a second partition 115 disposed on the intake surface 112. The second partition 115 can be disposed in the upper portion of the intake surface 112 and protrudes from the intake surface 112 in a direction perpendicular to the intake surface 112, and is generally arched in shape in the front view of the intake baffle structure (e.g., ...). Figure 6(As shown). The first partition 114 and the second partition 115 are arranged sequentially in the vertical direction, and the second partition 115 may be located below the first partition 114 in the vertical direction, and are configured to be approximately axially symmetrical with respect to the longitudinal axis of the suction baffle structure 10. When the suction baffle structure 10 is installed in a scroll compressor, the suction baffle 11 may be disposed inside the scroll compressor, and the first partition 114 and the second partition 115 may be disposed near the top of the suction port of the scroll compressor, so that they can cooperate with each other to block the upward flow path of gas entering the interior of the scroll compressor through the suction port. Two connecting partitions 116 are also provided on the suction surface 112, which extend obliquely from the two ends of the second partition 115 to the two side portions of the suction baffle 11, and these two connecting partitions 116 are approximately axially symmetrical with respect to the longitudinal axis of the suction baffle structure 10. The first partition 114, the second partition 115 and the connecting partitions 116 are all integrally formed with the body portion 111 of the suction baffle 12. When the intake baffle structure 10 is installed in the scroll compressor, the shape of the top portion of the second baffle 115 (i.e., semi-circular) can approximately match the shape of the corresponding portion of the intake port, thus blocking the upward flow path of gas entering the intake baffle structure from the intake port. When the shape of the top portion of the second baffle 115 approximately matches the shape of the corresponding portion of the intake port, the second baffle 115 can more effectively block the upward flow path of the gas. An exhaust window 117 is also provided in the body portion 111. This exhaust window 117 is positioned vertically below the second baffle 115, between the two connecting baffles 116, and vertically below the annular mounting portion 12. The exhaust window 117 is configured such that a portion of the gas entering the scroll compressor from the intake port can flow through this exhaust window 117 into the space below the annular mounting portion 12 for cooling the upper portion of the motor. The intake surface 112 has a windward surface 118 located vertically between the second baffle 115 and the exhaust window 117. For example, in this embodiment, the windward surface 118 may be substantially surrounded by the second baffle 115 and the exhaust window 117. This windward surface 118 may be configured as an inclined surface (i.e., the windward surface is inclined relative to the rest of the intake surface of the body portion, and the bottom of the windward surface is closer to the annular mounting portion than the top) to guide the gas entering the intake baffle structure toward the exhaust window 117, allowing the intake gas to flow more smoothly through the exhaust window 117 into the space below the annular mounting portion 12 and generally along the annular mounting portion 12. The inclined design of the windward surface 118 of the intake surface 112 can improve the utilization rate of the gas for cooling the upper part of the motor and reduce flow losses. Figure 8As shown, baffles 121 can be provided on the bottom surface of the annular mounting portion 12. Multiple baffles 121 can be provided, each with a different shape, and they extend substantially vertically from the bottom surface of the annular mounting portion 12 to obstruct gas flow in the path of the gas flowing along the annular mounting portion 12. For example, the baffles 121 can be provided at the threaded hole of the annular mounting portion 12 and appear as a circle partially surrounding the threaded hole in a bottom view. Alternatively, the baffles can be rectangular and extend radially in the annular mounting portion in a bottom view. Gas entering the space below the annular mounting portion 12 through the exhaust window 117 and flowing substantially along the annular mounting portion 12 can form vortices at the baffles 121, thereby creating a concentrated cooling area and more effectively cooling the upper part of the motor, thus improving the motor cooling effect.

[0050] Figure 9 This is a cross-sectional view of a scroll compressor equipped with an intake baffle structure according to the first embodiment of this utility model. The following refers to... Figure 9 The arrangement and working principle of the suction baffle structure according to the first embodiment of the present invention in a scroll compressor are described.

[0051] like Figure 9As shown, the scroll compressor has an intake port 2 and a compression mechanism. Gas from outside the scroll compressor can enter the interior of the scroll compressor through the intake port and then enter the compression mechanism for compression. An intake baffle structure is installed on the scroll compressor to guide and divert the gas entering the interior of the scroll compressor. In this embodiment, the annular mounting portion 12 of the intake baffle structure 10 is fixedly connected to the main bearing seat 1 of the scroll compressor by bolts. When the intake baffle structure 10 is installed in the scroll compressor, the intake baffle 11 of the intake baffle structure 10 is disposed inside the scroll compressor, and both the first partition 114 and the second partition 115 are disposed near the top of the intake port 2 of the scroll compressor. The shape of the top portion of the second partition 115 approximately matches the shape of the corresponding portion of the intake port 2. A gap exists between the second partition 115 and the intake port 2. The first partition 114 of the intake baffle 11 is located above the second partition 115 in the vertical direction, and a gap exists between the first partition 114 and the casing 3 of the scroll compressor. During the operation of the scroll compressor, gas is drawn into the scroll compressor through the intake port 2 and enters the intake baffle structure. The upward flow path of the gas entering the interior of the scroll compressor is first blocked by the second baffle 115 of the intake baffle structure 10. Therefore, most of the intake gas will not flow upward (i.e., only a small portion of the intake gas flows upward through the gap between the second baffle 115 and the intake port 2) and will leak upward from the intake baffle structure. Most of the intake gas will flow along the first path P1 and the second path P2 shown in the figure. Furthermore, the upward flow path of the small portion of gas flowing upward through the gap between the second baffle 115 and the intake port 2 will be further blocked by the first baffle 114, preventing it from directly leaking upward into the area outside the intake baffle. Only a smaller amount of gas can leak upward through the gap between the first baffle 114 and the casing 3 of the scroll compressor. This further ensures that only a small amount of gas leaks upward into the area outside the intake baffle structure, thereby reducing the amount of gas leaking upward from the intake baffle structure and improving the utilization rate of the gas for cooling the motor. The gas flowing along the first path P1 is guided by the windward surface 118 of the intake surface 112 and flows toward and through the exhaust window 117. It then flows below the annular mounting portion 12 of the intake baffle structure 10, cooling the upper part of the motor. The gas flowing along the annular mounting portion 12 forms a vortex at the location where the baffle 121 is provided in the annular mounting portion 12, improving the cooling effect. The gas flowing along the second path P2 flows downward along the downward-opening gas passage of the intake surface 112 to the bottom part of the scroll compressor, cooling the lower part of the motor.Therefore, by means of the intake baffle structure according to this utility model, a sufficient amount of intake gas can be used to cool the motor, and in particular, simultaneous cooling of both the upper and lower parts of the motor (i.e., uniform cooling of the motor) can be achieved, thereby effectively cooling the entire motor. In this embodiment, the ratio of the amount of gas flowing along the first path P1 to the amount of gas flowing along the second path P2 can be adjusted according to actual needs. For example, if the user wants more gas to flow along the first path P1, the area of ​​the exhaust window 117 can be increased. Through this appropriate diversion (i.e., the diversion of the flow ratio of gas entering the intake baffle structure via the lower gas channel and the middle exhaust window), the amount of lubricating oil flowing into the compression mechanism can also be appropriately controlled to achieve the desired oil circulation rate. For example, if it is desired to increase the oil circulation rate, the proportion of gas flowing through the lower gas channel can be increased so that the gas can carry more lubricating oil into the compression mechanism; while if it is desired to decrease the oil circulation rate, the proportion of gas flowing through the middle exhaust window can be increased so that the gas can carry less lubricating oil into the compression mechanism.

[0052] Figures 10a-13b Various modifications of the intake baffle structure according to the first embodiment of the present invention are shown. These modifications of the intake baffle structure are related to... Figure 5 The only difference between the intake baffle structure 10 shown is that the structure of the second partition of the intake baffle structure is different and / or there is an additional third partition, and the intake baffle may or may not have an exhaust window (the exhaust window is not shown in the figure), while the other configurations of the intake baffle structure are basically the same, so the relevant descriptions will be simplified or omitted.

[0053] Figure 10a and Figure 10b These are perspective and front views of a first variant of the suction baffle structure according to the first embodiment of the present invention. As shown, the suction baffle structure 20 includes a suction baffle 21, on which a first partition 212 and a second partition 213 are disposed. Unlike the second partition 115 described above, the second partition 213 is flat and substantially parallel to the first partition 212 in the front view of the suction baffle structure. Two connecting partitions 214 are also disposed on the suction surface 211, extending vertically from the two ends of the second partition 213 to the bottom of the suction baffle 21. When the suction baffle structure 20 is installed in the scroll compressor, the first baffle 212 and the second baffle 213 are both located near the top of the suction port of the scroll compressor. The second baffle 213 can be roughly aligned with the top of the suction port of the scroll compressor in the vertical direction, so that the upward flow path of the gas entering the interior of the scroll compressor from the suction port is blocked by the second baffle 213 and the first baffle 212.

[0054] Figure 11a and Figure 11b These are perspective and front views of a second variation of the suction baffle structure according to the first embodiment of the present invention. As shown, the suction baffle structure 30 includes a suction baffle 31, and a first partition 312, a second partition 313, and a third partition 314 are disposed on the suction surface 311 of the suction baffle 31. The configuration of the second partition 313 and its connecting partition is basically the same as that of the second partition 213 and its connecting partition as described above, and therefore will not be described in detail here. The configuration of the third partition 314 and its connecting partition is basically the same as that of the second partition 313 and its connecting partition, and is located in the space partially surrounded by the second partition 313 and its connecting partition. That is, the third partition 314 can be located below the second partition 313 in the vertical direction. When the suction baffle structure 30 is installed in the scroll compressor, the first baffle 312, the second baffle 313, and the third baffle 314 are all located near the top of the suction port of the scroll compressor. The third baffle 314 can be roughly aligned vertically with the top of the suction port of the scroll compressor, thus blocking the upward flow path of gas entering the interior of the scroll compressor from the suction port. Compared to the first variant, the second variant's suction baffle structure has additional baffles to block the upward flow of the suction gas, thereby further reducing the amount of upward gas leakage.

[0055] Figure 12a and Figure 12b These are perspective and front views of a third variation of the suction baffle structure according to the first embodiment of the present invention. As shown, the suction baffle structure 40 includes a suction baffle 41, and a first partition 412 and a second partition 413 are provided on the suction surface 411 of the suction baffle 41. The configuration of the second partition 413 is basically the same as that of the second partition 213 described above, and therefore will not be described in detail here. Two connecting partitions 414 are also provided on the suction surface 411. Each connecting partition 414 has a vertical section and a horizontal section connected to each other, wherein the vertical section is connected to the end of the second partition 413, and the horizontal section is connected to the side portion of the suction baffle 41. When the suction baffle structure 40 is installed in the scroll compressor, the first baffle 412 and the second baffle 413 are both located near the top of the suction port of the scroll compressor. The second baffle 413 can be roughly aligned with the top of the suction port of the scroll compressor in the vertical direction, so that the upward flow path of the gas entering the interior of the scroll compressor from the suction port is blocked by the second baffle 413 and the first baffle 412.

[0056] Figure 13a and Figure 13bThese are perspective and front views of a fourth variation of the suction baffle structure according to the first embodiment of this utility model. As shown, the suction baffle structure 50 includes a suction baffle 51, and a first partition 512 and a second partition 513 are provided on the suction surface 511 of the suction baffle 51. The configuration of the second partition 513 is basically the same as that of the second partition 413 described above, and therefore will not be described in detail here. Two connecting partitions 514 are also provided on the suction surface 511. Each connecting partition 514 has a vertical section and an oblique section connected to each other, wherein the vertical section is connected to the end of the second partition 513, and the oblique section is connected to the side portion of the suction baffle 51. When the suction baffle structure 50 is installed in the scroll compressor, the first baffle 512 and the second baffle 513 are both located near the top of the suction port of the scroll compressor. The second baffle 513 can be roughly aligned with the top of the suction port of the scroll compressor in the vertical direction, so that the upward flow path of the gas entering the interior of the scroll compressor from the suction port is blocked by the second baffle 513 and the first baffle 512.

[0057] In the following text, refer to Figures 14-16 This paper provides a brief description of the overall structure and working principle of the suction baffle structure for a scroll compressor according to the second embodiment of the present invention. The main difference between the suction baffle structure according to the second embodiment and the suction baffle structure according to the first embodiment is that the configuration of the suction baffle is different and it has separate components to form a partition. The other configurations of the suction baffle structure are basically the same, so relevant descriptions will be simplified or omitted.

[0058] Figure 14 This is an exploded view of the suction baffle structure for a scroll compressor according to the second embodiment of the present invention, wherein a tubular component separate from the suction baffle is shown. Figure 15 This is a front view of the intake baffle structure according to the second embodiment of the present invention, wherein the tubular component is omitted. See below for reference. Figure 14 and Figure 15 The air intake baffle structure according to the second embodiment of the present invention is described.

[0059] like Figure 14 and Figure 15As shown, the suction baffle structure 60 according to the second embodiment includes a suction baffle 61, an annular mounting portion 62, and a tubular member 63 separate from the suction baffle 61. The configuration of the suction baffle 61 is similar to that of the suction baffle 11 described above, the main difference being that the upper contour of the suction baffle 61 is composed of a partition 612 and two connecting partitions 613, and does not have any portion other than those. Therefore, the suction baffle 61 includes a body portion having a suction surface 611, and the suction baffle structure 60 includes a partition 612 and two connecting partitions 613. The suction surface 611 is for facing the suction port of the scroll compressor, and an exhaust window 614 is provided on the suction surface 611. The partition 612 is provided on the suction surface 611 and can be integrally formed with the body portion. The tubular member 63 can be used to be nested in the suction port of the scroll compressor. The tubular member 63 has a distal end 631 (for being nested in the intake port) and a proximal end 632 opposite to the distal end 631 (for cooperating with the intake baffle structure). The proximal end 632 can be used to cooperate with the intake baffle 61 and extend into the interior of the scroll compressor, so that the tubular member 63 can block the gap between the baffle 612 and the intake port from the inside of the intake baffle 611. The plane containing the opening at the distal end 631 of the tubular member 63 is perpendicular to the longitudinal axis of the tubular member 63, and the plane containing the opening at the proximal end 632 of the tubular member 63 is oblique to the longitudinal axis of the tubular member 63, such that the top longitudinal length of the portion of the tubular member 63 extending into the interior of the scroll compressor is greater than the bottom longitudinal length, and the opening at the proximal end 632 of the tubular member 63 is elliptical. Thus, in the side view of the tubular member 63 (e.g.) Figure 16 As shown, the proximal end 632 of the tubular member 63 has a beveled design, which ensures a sufficient amount of intake gas flows downward. When the intake baffle structure 60 is installed in the scroll compressor, the shape of the top portion of the partition 612 of the intake baffle 61 (i.e., semi-circular) roughly matches the shape of the corresponding portion of the intake port. The distal end 631 of the tubular member 63 is nested in the intake port of the scroll compressor, and the proximal end 632 extends toward the intake baffle 61 and into the interior of the scroll compressor, so that the upper portion of the proximal end 632 of the tubular member 63 can block the gap between the partition 612 and the intake port from the inside of the intake baffle. Therefore, the partition 612 of the intake baffle 61 and the upper portion of the proximal end 632 of the tubular member 63 together block the upward flow path of the gas entering the intake baffle structure. The partition 612 can constitute a first partition, while the upper portion of the proximal end 632 of the tubular member 63 can constitute a second partition located vertically below the first partition. A baffle plate can be provided on the bottom surface of the annular mounting portion 62.

[0060] Figure 16This is a cross-sectional view of a scroll compressor equipped with the suction baffle structure according to the second embodiment of this utility model. The following refers to... Figure 16 This paper describes the arrangement and working principle of the suction baffle structure according to the second embodiment of the present invention in a scroll compressor. Since the main difference between the suction baffle structure according to the second embodiment and the suction baffle structure according to the first embodiment lies in the different configurations of the suction baffle and partition, while other configurations of the suction baffle structure are basically the same, relevant descriptions will be simplified or omitted.

[0061] like Figure 16 As shown, the annular mounting portion 62 of the suction baffle structure 60 is fixedly connected to the main bearing housing 1 of the scroll compressor. The shape of the top portion of the partition 612 of the suction baffle structure 60 approximately matches the shape of the corresponding portion of the suction port 2. The distal end 631 of the tubular member 63 of the suction baffle structure 60 is nested in the suction port 2 of the scroll compressor, and the proximal end 632 extends toward the suction baffle 611 of the suction baffle structure 60 and enters the interior of the scroll compressor, so that the upper portion of the tubular member 63 can block the gap between the partition 612 and the suction port from the inside of the suction baffle. Thus, the partition 612 of the suction baffle 61 (i.e., the first partition) and the upper portion of the proximal end 632 of the tubular member 63 (i.e., the second partition) together block the upward flow path of the gas entering the suction baffle structure. During the operation of the scroll compressor, gas is drawn into the scroll compressor through the intake port 2. The gas entering the compressor is essentially unable to flow upwards due to the combined obstruction of the baffle 612 and the upper portion of the proximal end 632 of the tubular member 63, thus flowing along the first path P1 and the second path P2 shown in the figure. The beveled design of the proximal end 632 of the tubular member 63 of the intake baffle structure 60 helps to allow the gas to flow more smoothly along the second path P2. The gas flowing along the first path P1 flows through the exhaust window 614 and then flows along the annular mounting portion 62 below the intake baffle structure 60 to cool the upper portion of the motor. The gas flowing along the annular mounting portion 62 will form a vortex at the location where the baffle is provided in the annular mounting portion 62 to improve the cooling effect. The gas flowing along the second path P2 will flow along the lower gas passage of the intake surface 611 to reach the bottom portion of the scroll compressor to cool the lower portion of the motor. Compared with the intake baffle structure according to the first embodiment, the intake baffle structure according to the second embodiment has a tubular member, and the upper part of the proximal end of the tubular member (i.e., the second partition) can be used to block the gap between the partition (i.e., the first partition) and the intake port from the inside of the intake baffle. Therefore, a better effect of blocking gas flow can be obtained, thereby further reducing the amount of gas leaking upward from the intake baffle structure and improving the utilization rate of gas for cooling the motor.

[0062] Figure 17 and Figure 18 A variation of the tubular member of the intake baffle structure according to the second embodiment of the present invention is shown, while Figure 19 It is installed with, including, Figure 17 and Figure 18 The diagram shows a cross-sectional view of a scroll compressor with a suction baffle structure according to the second embodiment of the present invention, showing a variation of the tubular component. Figure 19 The suction baffle structure shown is similar to Figures 14-16 The only difference between the suction baffle structures shown is the shape of the tubular component; the other configurations of the suction baffle structures are basically the same, so the relevant descriptions will be simplified or omitted.

[0063] like Figure 17 and Figure 18 As shown, the tubular member 64 has a distal end 641 and a proximal end 642 opposite to the distal end 641. Unlike the tubular member 63 described above, the planes containing the openings at both the distal end 641 and the proximal end 642 of the tubular member 64 are perpendicular to the longitudinal axis of the tubular member 64, such that the longitudinal length of the top of the tubular member 64 is approximately equal to the longitudinal length of the bottom of the tubular member 64. Therefore, the proximal end 642 of the tubular member 64 does not have a beveled design. Figure 19 As shown, when the suction baffle structure including the tubular member 64 is installed in the scroll compressor, the distal end 641 of the tubular member 64 is nested in the suction port of the scroll compressor, and the proximal end 642 extends towards the suction baffle and enters the interior of the scroll compressor, so that the upper portion of the tubular member 64 can block the gap between the baffle and the suction port from the inside of the suction baffle. Thus, the baffle of the suction baffle (i.e., the first baffle) and the upper portion of the proximal end 642 of the tubular member 64 (i.e., the second baffle) together block the upward flow path of the suction gas. Compared with the tubular member 63 described above, the configuration of the tubular member 64 is more standardized, and therefore the manufacturing process is simpler.

[0064] Furthermore, it should be noted that although different technical solutions for the suction baffle structure for a scroll compressor according to the present invention have been described in the foregoing embodiments, it is understood that the technical solutions in the above embodiments are merely illustrative and not restrictive, and various modifications can be made according to actual needs, such as those described below. The annular mounting portion of the suction baffle structure can be separate from the suction baffle and fixedly connected to the suction baffle by fasteners. In the suction baffle structure according to the first embodiment, the shape of the top portion of either or both of the first and second partitions can be configured to conform to the shape of the top portion of the suction port of the scroll compressor. Various modifications of the suction baffle structure according to the first embodiment can include an exhaust window. The configuration of the partitions in the suction baffle structure is not limited to those described in the above embodiments, but can have other shapes according to actual needs, and the number of partitions is not limited to two or three.
