Description

Technical Field

[0001] This invention relates to the field of compressors, and more specifically to a support structure for a liquid receiver in a horizontal compressor. Background Technology

[0002] Due to the height limitation of the pump body, if the weld points of the liquid receiver bracket are arranged axially along the side wall and the weld points are on both sides of the liquid receiver cylinder, interference between the three-point weld holes on the front side and the side wall and insufficient position on the rear side will occur. In order to avoid the above situations, measures such as moving the circumferential position of the three-point weld holes on the side wall and lengthening the space at the rear of the pump body are generally adopted.

[0003] like Figure 1 , Figure 2 and Figure 3 The diagram shows a schematic of a liquid receiver support structure for a horizontal compressor in the prior art. The liquid receiver support structure 8 includes an arc-shaped support part 2 and a connecting seat 1, the connecting seat 1 having a first clamping notch 3. The connecting seat 1 is spot-welded to the circumference 9 of the lower cover of the horizontal compressor 5 housing, fixing the connecting seat 1 to the housing of the horizontal compressor 5. In this case, the position of the spot weld is close to the vicinity of the circumferential weld 9 on the lower cover. The solder at the circumferential weld 9 is affected by the high temperature during spot welding, making the stability of the arc welding parameters and manual operation highly dependent, requiring high operational skill and posing significant control challenges. Figure 1 As can be seen, the first clamp notch 3 is located between the connecting seat 1 and the arc-shaped support 2. To facilitate the assembly of the clamp 7 at this position, the reserved notch area at the connection between the connecting seat 1 and the arc-shaped support 2 is large. Therefore, the strength at this point is relatively weak, and the bracket is prone to deformation under stress, which may lead to the breakage at the connection between the connecting seat 1 and the arc-shaped support 2. Summary of the Invention

[0004] In view of the problems in the prior art, the purpose of this invention is to overcome the shortcomings of the prior art and provide a novel liquid reservoir support structure, which can reduce the difficulty of welding the support to the compressor housing and improve the strength of the support structure.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] This invention provides a compressor receiver support structure, comprising: a connecting seat, the bottom of which is fixed to the side wall of the horizontal compressor, the connecting seat connecting to the side of the horizontal compressor forming a center protrusion facing away from the compressor housing, the connecting seat extending circumferentially along the compressor; and an arc-shaped support portion connected to the side of the connecting seat, the arc-shaped support portion being used to enclose and tighten the receiver with an arc-shaped clamp.

[0007] In some embodiments, the connector includes a top portion, a middle portion, and a support arm, with the support arm connected to the top portion of the connector via the middle portion, making the connector an integral structure.

[0008] In some embodiments, the connecting seat includes two connecting seat middle portions and two support arms. The two support arms are respectively connected to the top of the connecting seat through the corresponding connecting seat middle portions. The two support arms extend to both sides of the arc-shaped support portion, so that the connecting seat and the arc-shaped support portion are combined into a Y-shaped structure.

[0009] In some embodiments, the arc-shaped support is connected to the side of the top of the connecting seat, and the connecting seat is fixedly connected to the side wall of the horizontal compressor via the support arm.

[0010] In some embodiments, the support arm is fixedly connected to the side wall of the horizontal compressor by pressure welding.

[0011] In some embodiments, the top of the connecting seat is provided with a first clamp notch for one end of the arc-shaped clamp to pass through, and the central axis of the first clamp notch is parallel to the central axis of the horizontal compressor.

[0012] In some embodiments, the bottom of the arc-shaped support is provided with a second clamp notch, through which the other end of the arc-shaped clamp passes, and the central axis of the second clamp notch is parallel to the central axis of the horizontal compressor.

[0013] In some embodiments, the bending angle formed by the connection between the middle part of the connecting seat and the support arm is an obtuse angle.

[0014] In some embodiments, the top of the arc-shaped support is fitted to the reservoir housing so that the reservoir is placed perpendicular to the horizontal plane.

[0015] This invention also provides a compressor, including the liquid receiver support structure as described in any one of claims 1-9.

[0016] The technical advantages achieved by this invention are as follows: In this solution, the liquid receiver support structure is modified to be connected along the circumferential direction of the compressor via a connecting seat, effectively avoiding the three-six point welding positions on the side wall of the housing and the circumferential welding positions on the lower housing cover. This structure reduces the operational difficulty during welding and improves the process accuracy. In a preferred embodiment, the connecting seat of the liquid receiver support structure is pressure welded to the arc surface of the compressor housing, resulting in a higher fit with the side wall of the housing and a more stable support for the liquid receiver. The connecting seat can be prefabricated and pressure welded to the surface of the compressor housing, greatly improving accuracy and enhancing the vibration resistance and deformation resistance of the liquid receiver support structure. In a further preferred embodiment, the clamp notch is located at the top of the connecting seat, which improves the vibration resistance and deformation resistance of the support structure and ensures the compactness of the clamp assembly.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0039] Example 1

[0040] Figure 4This embodiment provides a novel liquid reservoir support structure. It includes a connecting seat 11 and an arc-shaped support portion 15. The bottom of the connecting seat 11 is fixed to the side wall of the horizontal compressor 5. The connecting seat 11 connects to the side of the horizontal compressor 5, forming a central protrusion facing away from the housing of the compressor 5. The connecting seat 11 extends circumferentially along the compressor 5. Specifically, the connecting seat 11 consists of a connecting seat top 12, two connecting seat middle portions 13, and two support arms 14. The support arms 14 are respectively connected to the connecting seat top 12 through their corresponding connecting seat middle portions 13, making the connecting seat 11 an integral structure. The overall structure of the connecting seat 11 is U-shaped. The connecting seat top 12 has a regularly shaped (e.g., rectangular, circular) small hole, which is a first clamp notch 16, used to fit one end of an arc-shaped clamp 7. The central axis of the first clamp notch 16 is parallel to the central axis of the horizontal compressor 5. This design helps to improve the problem of weak stress and easy deformation of the groove at the connection between the connecting seat 1 and the arc-shaped support 2 in the prior art. For example... Figure 8 As shown, the arc-shaped support 15 is connected to the side of the connecting seat 11. The arc-shaped support 15 is used to enclose and tighten the liquid reservoir 6 with an arc-shaped clamp 7. The curvature of the arc-shaped support 15 is the same as the curvature of the side wall of the liquid reservoir 6 to ensure a better fit between the arc-shaped support 15 and the liquid reservoir 6. The bottom of the arc-shaped support 15 is provided with a second clamp notch 17 for the other end of the arc-shaped clamp 7 to pass through. The central axis of the second clamp notch 17 is parallel to the central axis of the horizontal compressor 5. The arc-shaped clamp 7, through the first clamp notch 16 and the second clamp notch 17, encloses and tightens the liquid reservoir 6 with the arc-shaped support 15 of the liquid reservoir bracket 8.

[0041] Figure 5 This is a front view of the reservoir support structure in Embodiment 1. As can be seen from the figure, the two support arms 12 extend to both sides of the arc-shaped support portion 15, so that the connecting seat 11 and the arc-shaped support portion 15 combine to form a Y-shaped structure. Furthermore, it can be seen that the bend formed by the connection between the top 12 and the middle 13 of the support portion is at an obtuse angle. This design allows the reservoir support 8 to more stably support the reservoir, resulting in superior stability. Figure 6 and Figure 7 The morphology of the novel reservoir support structure, as seen from top and side views, is presented to further understand the Y-type reservoir support structure.

[0042] Figure 8This is a schematic diagram of the liquid reservoir support structure fixing the liquid reservoir onto the compressor in Embodiment 1. As shown in the diagram, the support arm 14 on the connecting seat 11 of the liquid reservoir support structure 10 extends circumferentially along the side wall of the compressor 5 and is welded to it. The arc-shaped support portion 15 fits snugly against the side wall shell of the liquid reservoir 6. In this embodiment, the support arm 14 is pressure-welded to the arc surface of the compressor 5, resulting in a higher degree of fit with the side wall of the compressor 5 shell and a more stable support for the liquid reservoir 6. The liquid reservoir support 10 cooperates with the arc-shaped clamp 7, allowing the liquid reservoir 6 to be placed perpendicular to the horizontal plane. Figure 8 It can also be seen that the reservoir support structure 10 completely avoids the circumferential weld 9 of the lower shell cover, and the welded part of the support structure 10 will not interfere with the circumferential weld of the lower shell cover. In addition to avoiding the circumferential weld 9 of the lower shell cover, the reservoir support structure 10 also effectively avoids the three-six-point weld 19 on the side wall, such as... Figure 9 As shown.

[0043] In addition, the present invention also has other modified embodiments, such as:

[0044] In Embodiment 2, the support arm 14 can be bolted to the side wall of the horizontal compressor 5, which facilitates the replacement of the reservoir support structure 10. Alternatively, in Embodiment 3, the arc length of the arc-shaped support 15 can be increased, increasing the contact area between the arc-shaped support 15 and the reservoir 6, thus aiding in the fixation of the reservoir support structure 10 to the reservoir 6. Or, in Embodiment 4, the number of support arms 14 can be one or more, welded to the arc surface of the compressor 5. The combination of the connecting seat 11 and the arc-shaped support 15 is not limited to a Y-shaped structure; other shapes are also possible and fall within the scope of this invention.

[0045] In summary, the reservoir support structure of this embodiment has the following beneficial effects:

[0046] In this design, the liquid receiver bracket structure is welded to the casing wall along the circumferential direction of the horizontal compressor. This effectively avoids the circumferential weld of the lower casing cover and the three-six point weld of the upper cylinder cover, minimizing the impact on the welding of these two parts, reducing the difficulty of the bracket welding process, and improving the welding precision. The connecting seat of the liquid receiver bracket structure can be pressure welded to the arc surface of the compressor casing, resulting in a higher fit with the casing sidewall and more stable support for the liquid receiver. The connecting seat can be prefabricated and pressure welded to the surface of the compressor casing, greatly improving precision and enhancing the vibration resistance and deformation resistance of the liquid receiver bracket structure. Furthermore, the first clamp notch for the arc-shaped clamp in the liquid receiver bracket structure has been moved from the connection point between the connecting seat and the arc-shaped bracket to the top center of the connecting seat, increasing the stress strength at the connection point and making the two connection points less prone to deformation and breakage. Simultaneously, this structure also improves the stability of the bracket and reduces the overall noise of the compressor.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0048] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
