Compressor assembly and air conditioner

Abstract

The application discloses a compressor assembly and an air conditioner. The compressor assembly comprises a compressor, a pipeline connected with the compressor, a buffer assembly and a mounting seat. The buffer assembly is connected with the mounting seat and the compressor and comprises an elastic member. The elastic member is used for buffering the torsion of the compressor around the axis of the compressor. When the buffer assembly is used for buffering the torsion generated by the shutdown of the compressor, the elastic member can generate a reaction force to buffer the torsion of the compressor, thereby, it is beneficial to avoid the swing of the pipeline (the suction pipe and / or the exhaust pipe) connected with the compressor, and further, it is beneficial to avoid the problem that the stress of the pipeline exceeds the standard or even the pipeline is broken due to fatigue. When the buffer assembly is used for buffering the torsion generated by the start of the compressor, the working principle and the role of the buffer assembly are the same as the foregoing, and details are not described herein.

Description

Technical Field

[0001] This application relates to equipment having a compressor, and more particularly to compressor components and air conditioners. Background Technology

[0002] As living standards improve, air conditioners are used more and more frequently, including the compressor. The compressor vibrates strongly when it stops or starts, causing significant swaying of the pipes connected to it (sometimes called piping, such as the intake and exhaust pipes). This can lead to excessive stress on the pipes, and with prolonged use, may result in fatigue cracking and pipe breakage. Utility Model Content

[0003] The purpose of this application is to disclose a compressor assembly and an air conditioner, wherein the compressor assembly helps to avoid the problem of excessive stress in the pipeline connected to the compressor.

[0004] In a first aspect, this application discloses a compressor assembly. The compressor assembly includes a compressor, piping connected to the compressor, a buffer assembly, and a mounting base. The buffer assembly connects the mounting base and the compressor and includes an elastic element; the elastic element is used to buffer the torsion of the compressor about its axis.

[0005] In some embodiments, the compressor includes a compressor boss, and the buffer assembly is movably connected to the compressor boss.

[0006] In some embodiments, the buffer assembly includes a first elastic element and a second elastic element, wherein the direction of the elastic restoring force of the first elastic element is opposite to the direction of the elastic restoring force of the second elastic element.

[0007] In some embodiments, the compressor boss includes a through hole, and the buffer assembly further includes an elastic element mounting post that passes through a second elastic element, the through hole, and the first elastic element. The elastic element mounting post is clearance-fitted with the wall of the through hole to achieve the movable connection. Alternatively, the compressor boss includes two through holes; the buffer assembly further includes a first elastic element mounting post and a second elastic element mounting post. The first elastic element mounting post passes through the first elastic element and one of the through holes, and is clearance-fitted with the wall of the through hole to achieve the movable connection. The second elastic element mounting post passes through the second elastic element and the other through hole, and is clearance-fitted with the wall of the through hole to achieve the movable connection.

[0008] In some embodiments, the gap between the elastic element mounting post and one side of the hole wall is d, where d ≥ 0.5 mm. The gap between the first elastic element mounting post and the corresponding side of the hole wall is d, where d ≥ 0.5 mm; the gap between the second elastic element mounting post and the corresponding side of the hole wall is d, where d ≥ 0.5 mm.

[0009] In some embodiments, the mounting base includes a mounting base protrusion, one end of the elastic element mounting post is fixedly connected to the mounting base protrusion, and the other end of the elastic element mounting post is suspended.

[0010] In some embodiments, the compressor boss protrudes radially from the compressor, and the elastic mounting post is perpendicular to the compressor boss.

[0011] In some embodiments, the elastic element is a helical spring with an inner diameter of [missing information]. The diameter of the elastic element mounting post is

[0012] In some embodiments, there are multiple buffer components that are evenly distributed along the circumference of the compressor.

[0013] Secondly, this application discloses an air conditioner. The air conditioner includes any of the aforementioned compressor components.

[0014] The compressor's vibration is primarily characterized by torsional motion around its axis. Since the buffer assembly is connected to both the compressor and the mounting base, and includes an elastic element, when the buffer assembly is used to buffer the torsional motion generated during compressor shutdown, the elastic element generates a reaction force to cushion the compressor's torsional motion around its axis. This helps prevent the pipes connected to the compressor (intake and / or exhaust pipes) from swinging, and consequently, helps prevent excessive stress in the pipes during shutdown, or even fatigue fracture. When the buffer assembly is used to buffer the torsional motion generated during compressor startup, its working principle and function are the same as described above and will not be repeated here.

[0023] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0024] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0025] See Figures 1 to 6This application discloses a compressor assembly. The compressor assembly is a component of an air conditioner, but can also be a non-air conditioner component. The compressor assembly includes a compressor 1, piping 2 (also called wiring, such as an intake pipe and / or exhaust pipe) connected to the compressor, a buffer assembly 3, and a mounting base 4. The compressor 1 includes a compressor body 11 and a compressor base 12 for the compressor body 11. The compressor body 11 is typically cylindrical, but not limited to this. The mounting base 4 is used to mount the buffer assembly 3; in the air conditioning field, the mounting base 4 can be an air conditioner base plate. In this case, one assembly method of the mounting base 4 and the compressor 1 is as follows: the compressor base 12 protrudes with a compressor mounting platform 120. The mounting base 4 protrudes with a mounting base boss 40. There are three compressor mounting platforms 120 and three mounting base bosses 40, and the number is not limited to this. The compressor assembly also includes three shock absorbers 5. Each mounting boss 40 is provided with a connecting post, and the shock absorber 5 passes through each connecting post, so that the shock absorber 5 is provided between each mounting boss 40 and each compressor mounting platform 120.

[0026] The buffer assembly 3 connects the mounting base 4 and the compressor 1. Its connection position to the compressor 1 is not limited. It buffers the torsion of the compressor 1 around its axis, particularly the torsion generated during startup or shutdown. The buffer assembly 3 includes an elastic element. Figure 8 The diagram illustrates a first elastic element 311 for buffering the torsional movement of compressor 1 during startup, and a second elastic element 312 for buffering the torsional movement of compressor 1 during shutdown. The number of first elastic elements 311 is not limited to one, and the number of second elastic elements 312 is limited to one. The assembly method of the elastic elements with other components of the buffer assembly 3 is not limited. When the compressor body 11 is cylindrical, the elastic element extends along the tangent of the compressor body 11, which can also be understood as a direction perpendicular to the compressor's axis. Regardless of the arrangement, the elastic element is used to buffer the torsional movement of compressor 1 around its axis. The assembly method of the elastic element is not limited, as long as it serves a buffering function. For example, one end of the elastic element abuts against the compressor 1, and the other end abuts against the mounting base 4. This abutment can be direct as shown in the diagram, or indirect. The structure of the elastic element is also not limited; it can be a spring (not limited to the helical spring shown in the diagram), elastic rubber, elastic plastic, dielectric elastomer, etc. The buffer assembly 3 may include only the elastic element or other components.

[0027] The vibration of compressor 1 is mainly characterized by torsion around its axis (for example, when the compressor body 11 is cylindrical, the torsion is mainly along the tangential direction of the compressor body 11). Therefore, since the buffer assembly 3 is connected to the compressor 1 and the mounting base 4 and includes an elastic element, when the compressor 1 stops, the elastic element generates a reaction force to buffer the torsion of the compressor 1 around its axis. This helps to prevent the pipes 2 (intake pipe and / or exhaust pipe) connected to the compressor 1 from swinging, and further helps to prevent excessive stress in the pipes or even fatigue fracture caused by shutdown. When the buffer assembly 3 is used for vibration reduction during compressor 1 startup, the elastic element generates a reaction force, and the principle and function are the same as described above, so they will not be repeated here. In summary, the buffer assembly can buffer the torsion around the compressor axis generated during compressor shutdown or startup, thereby preventing excessive stress in the pipes.

[0028] In some related technologies, the piping (i.e., pipeline) is connected to the compressor 1 via a non-movable elastic element. During normal operation of the compressor, this causes stress and noise in the piping. Although this can solve the problem of excessive stress, it only constrains the piping through the elastic element connected to the piping and the compressor. The piping vibrates due to the vibration of the compressor. This application uses a buffer assembly connected to the compressor and the mounting base to constrain the source of vibration, thus better solving the problem of excessive stress.

[0029] See Figure 2 , Figure 4 , Figure 6 and Figure 7 The compressor 1 includes a compressor boss 121. In this application, the compressor boss 121 is disposed on the compressor base 12. The buffer assembly 3 is movably connected to the compressor boss 121. The movable connection is not limited to the way the elastic mounting post passes through the compressor boss 121 as described later. The purpose of the movable connection is not to affect the operation of the compressor 1, but to allow the buffer assembly 3 to play a buffering role.

[0030] As described above, since the buffer assembly 3 is movably connected to the compressor boss 121, this movable connection ensures that there are no additional constraints on the compressor 1 during normal system operation. Therefore, it does not affect the normal operation of the compressor 1, nor does it cause noise or stress due to constraints. In contrast, in the aforementioned embodiment where the piping and compressor 1 are not movably connected via an elastic element, the normal operation of the compressor causes stress and noise in the piping.

[0031] Normally, a buffer component 3 can buffer the torsional motion around the compressor 1 axis during shutdown or startup. Therefore, in order to buffer the torsional motion during both shutdown and startup, see [reference needed]. Figure 2 , Figure 4 and Figure 6 The buffer assembly 3 includes a first elastic element 311 and a second elastic element 312. The direction of the elastic restoring force of the first elastic element 311 is opposite to the direction of the elastic restoring force of the second elastic element 312. How the opposite directions of the elastic restoring forces are achieved is not limited; for example, the first elastic element 311 is located on the left side of the compressor boss 121, and the second elastic element 312 is located on the right side of the compressor boss 121. The way the other ends of the first elastic element 311 and the second elastic element 312 are fixed is not limited, as long as they can provide support for the other ends of the first elastic element 311 and the second elastic element 312 respectively, allowing either the first elastic element 311 or the second elastic element 312 to deform.

[0032] The following provides a more detailed explanation of how the compressor assembly, with the first elastic element 311 and the second elastic element 312, buffers the torsion during the start-up or shutdown of the compressor 1, so that the stress in the pipeline ultimately meets the standard.

[0033] Assuming the direction of the torsion generated during the startup of compressor 1 is clockwise, the first elastic element 311 generates a counterclockwise reaction force to buffer the torsion of compressor 1, thereby helping to prevent excessive stress in pipeline 2. The shutdown process is the reverse of the startup process. During shutdown, the torsion generated by compressor 1 is counterclockwise. Therefore, the second elastic element 312 generates a clockwise reaction force to buffer the torsion of compressor 1, thereby helping to prevent excessive stress in pipeline 2.

[0034] See Figure 2 , Figure 4 , Figures 6 to 8 The first embodiment of the buffer assembly 3 is described as follows: the compressor boss 121 includes a through hole 1210, and the buffer assembly 3 further includes an elastic element mounting post 313. The elastic element mounting post 313 passes through the second elastic element 312, the through hole 1210, and the first elastic element 311. The elastic element mounting post 313 is clearance-fitted with the wall of the through hole 1210 to achieve the movable connection.

[0035] As described above, the buffer assembly 3 has fewer parts and a simpler structure, with the elastic element mounting post 313 passing through the second elastic element 312, the through hole 1210 and the first elastic element 311, and the elastic element mounting post 313 and the hole wall of the through hole 1210 having a clearance fit.

[0036] The elastic element mounting post 313 is shared by the first elastic element 311 and the second elastic element 312. In a variation, the first elastic element 311 and the second elastic element 312 do not share the elastic element mounting post 313. This variation is as follows: The compressor boss 121 includes two through holes 1210. The buffer assembly 3 includes a first elastic element mounting post and a second elastic element mounting post. The first elastic element mounting post passes through the first elastic element 311 and one of the through holes 1210, and has a clearance fit with the hole wall of the through hole to achieve the movable connection; the second elastic element mounting post passes through the second elastic element 312 and the other through hole, and has a clearance fit with the hole wall of the through hole to achieve the movable connection.

[0037] As described above, the first elastic element mounting post passes through the first elastic element 311 and also has a clearance fit with a through hole 1210 to achieve the movable connection. The second elastic element mounting post passes through the second elastic element 312 and also has a clearance fit with the wall of another through hole to achieve the movable connection. The structure is simple and also ensures that the buffer assembly 3 will not affect the operation of the compressor 1. The buffer assembly 3 will not cause the compressor to exceed the stress limit under normal operation, shutdown or startup conditions.

[0038] When the elastic element mounting post 313 passes through the through hole 1210, the clearance between the elastic element mounting post 313 and one side of the hole wall of the through hole 1210 is d, where d ≥ 0.5 mm, for example, 0.5 mm, 1 mm, 1.5 mm, or 2.0 mm, etc. When the first elastic element mounting post passes through one through hole and the second elastic element mounting post passes through another through hole, the clearance between the first elastic element mounting post and the corresponding hole wall on one side is d, where d ≥ 0.5 mm; the clearance between the second elastic element mounting post and the corresponding hole wall on one side is also d, where d ≥ 0.5 mm. Of course, the clearance between the first elastic element mounting post and the corresponding hole wall on one side may not be equal to the clearance between the second elastic element mounting post and the corresponding hole wall on one side.

[0039] See Figure 2 , Figure 4 , Figures 6 to 8The mounting base 4 includes a mounting base protrusion 41. When the compressor boss 121 includes a through hole 1210, one end of the elastic element mounting post 313 is fixedly connected to the mounting base protrusion 41. The method of fixing is not limited; for example, one end of the elastic element mounting post 313 is threaded to the mounting base protrusion 41. The other end of the elastic element mounting post 313 is suspended. More specifically, the elastic element mounting post 313 includes an end cap 3131. The two ends of the second elastic element 312 abut against the end cap 3131 and the compressor boss 121, respectively. The two ends of the first elastic element 311 abut against the compressor boss 121 and the mounting base protrusion 41, respectively. Therefore, the direction of the elastic restoring force of the first elastic element 311 is opposite to the direction of the elastic restoring force of the second elastic element 312. In other embodiments, the other end of the elastic element mounting post 313 may not be suspended. A mounting base protrusion 41 is added to the mounting base 4 shown in the figure, and the other end of the elastic element mounting post 313 is fixedly connected to the newly added mounting post protrusion 41.

[0040] As described above, since the other end of the elastic element mounting post 313 is suspended, the elastic element mounting post 313 only needs to be fixedly connected to the mounting base protrusion 41 at one end, and the other end is an end cap 3131. The structure of the elastic element mounting post 313 is simple, and the buffer assembly 3 is not only simple in structure, but also easy to install with the mounting base 4.

[0041] See Figure 7 The compressor boss 121 protrudes in a direction perpendicular to the compressor's axis. For example, if the compressor body 11 is cylindrical, the direction perpendicular to the axis might be radial, and the compressor boss 121 would protrude radially from the compressor 1. See also... Figure 6 The elastic mounting post 313 is perpendicular to the compressor boss 121.

[0042] As described above, the compressor boss 121 protrudes in a direction perpendicular to the axis of the compressor 1 (e.g., radial protrusion of the compressor), which makes it easier for the elastic element mounting post 313 to be perpendicular to the compressor boss 121. Furthermore, the elastic element can be located more conveniently and accurately in a direction perpendicular to the axis of the compressor 1. For example, when the compressor body 11 is cylindrical, the elastic element is located in the tangential direction of the compressor body 11.

[0043] In the foregoing embodiments, the elastic element (at least one of the first elastic element and the second elastic element) is a helical spring with an inner diameter of [missing information]. The diameter of the elastic element mounting post 313 is For example, 1mm, 2mm or 3mm, etc.

[0044] As set up above, due to On the one hand, it facilitates the insertion of the elastic element into the elastic element mounting post 313; on the other hand, it allows the elastic element to deform freely, effectively buffering the torsion of the compressor 1.

[0045] There may be only one buffer component 3 to ensure that the stress does not exceed the limit; however, those skilled in the art will understand that there may be multiple buffer components 3, evenly distributed along the circumference of the compressor 1. The circumferential distribution along the compressor 1 includes: a) as... Figure 2 , Figure 4 and Figure 6 As shown, each of the buffer components 3 is uniformly distributed laterally on the compressor 1. More specifically, with the radial plane of the compressor 1 as the projection plane, the projection of each buffer component 3 is located outside the outline of the projection of the compressor 1; b) each of the buffer components 3 is uniformly distributed circumferentially at the bottom of the compressor 1, and the projections of all the buffer components 3 are located within the outline of the projection of the compressor 1. In other embodiments, there are multiple buffer components 3, which are not uniformly distributed circumferentially on the compressor 1.

[0046] As described above, since the buffer assembly 3 is evenly distributed along the circumference of the compressor 1, the reaction force on the compressor 1 is uniform, which is more conducive to avoiding the twisting of the compressor 1, and thus more conducive to avoiding the stress of the pipeline 2 exceeding the standard.

[0047] See Figure 1 Using the height of compressor 1 at 1 / 2 as a reference, Figure 1 The reference mark is L. The mounting base 4 is located at the bottom of the compressor 1, and the axial projection of the compressor 1 lies within the outline of the mounting base 4. The buffer assembly 3 is lower than the reference mark L. In this embodiment, the buffer assembly 3 is connected to the mounting base protrusion 41, which facilitates the implementation of this scheme. For example, the mounting base protrusion 41 does not need to be too high, etc., making it easier to implement.

[0048] Figure 1 This can be understood as constraining the lower part (e.g., the bottom) of compressor 1. In other embodiments, the upper part of compressor 1 can also be constrained. That is, with half the height of compressor 1 as a reference, the buffer assembly 3 is higher than the reference L. The bottom of compressor 1 is installed with related structures, while the top of compressor 1 is free. By having the buffer assembly 3 higher than the reference L, both the upper and lower parts of compressor 1 are constrained, which also helps to prevent excessive stress on pipeline 2.

[0049] Secondly, this application discloses an air conditioner. The air conditioner includes a compressor assembly as described in any of the foregoing descriptions. How the compressor assembly, along with other components, constitutes the air conditioner will not be elaborated further.

[0050] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
