Description

Technical Field

[0001] This application relates to the field of compressors, and more particularly to a support structure, a compressor, and household appliances. Background Technology

[0002] As is well known, during transportation, the outdoor unit of an air conditioner is subjected to axial low-frequency loads below 50Hz from the road surface, and the compressor's rigid body mode is also within this load. When the compressor is subjected to axial low-frequency loads from the road surface, it will shake, which can lead to excessive stress on the transported pipelines or even fatigue fracture of the pipelines.

[0003] Currently, in order to reduce the impact load on the pipeline, rigid constraint components are set between the foot pads and connectors in the support structure corresponding to the compressor to limit the compressor's shaking, thereby reducing the impact load on the pipeline.

[0004] However, the rigid constraint components used have the problem of being difficult to disassemble and assemble. Utility Model Content

[0005] This application provides a support structure, a compressor, and a household appliance. It solves the problem of difficult disassembly and assembly of rigid, hard-constrained components in existing support structures. The technical solution is as follows: In the first aspect, a support structure is provided, including: a connecting column, a foot pad, a limiting pad, and a connector; The foot pad, the limiting pad, and the connector are all sleeved on the connecting post, and the foot pad is movably connected to the connecting post, while the connector is securely connected to the connecting post. In the axial direction of the connecting column, the limiting gasket is located between the foot pad and the connecting member, and the limiting gasket is configured to melt after reaching a temperature above a preset temperature.

[0006] The use of limiting gaskets that melt at temperatures exceeding a preset limit facilitates installation. Since the limiting gaskets fitted onto the connecting columns melt at these temperatures, disassembly is unnecessary, eliminating the need for removal and simplifying the installation and removal of limiting gaskets in the support structure. Furthermore, because the limiting gaskets on the connecting columns melt at temperatures exceeding the preset limit, they are flexible structures. This allows the limiting gaskets located between the foot pads and connectors to make soft contact with adjacent foot pads and connectors, effectively reducing axial impact loads. Moreover, the foot pads in the support structure can be designed to be softer for better operational vibration isolation.

[0007] In some possible implementations, the thickness of the limiting shim is greater than the distance between the foot pad and the connector before the connecting post is compressed axially.

[0008] The thickness of the limiting shim is greater than the distance between the foot pad and the connector before it is compressed in the axial direction of the connecting column. In other words, the limiting shim installed between the foot pad and the connector will keep the foot pad in a compressed state. In this way, the probability of axial swaying of the support structure can be better reduced during transportation, thus effectively reducing axial impact load.

[0009] In some possible implementations, the thickness of the limiting pad is greater than the amount of compression of the foot pad in the axial direction of the connecting post.

[0010] By making the thickness of the limiting shim greater than the axial compression of the foot pad on the connecting column, a gap can be maintained between the foot pad and the connecting part before the limiting shim is installed. This means that even after the limiting shim melts, there will still be a certain gap between the foot pad and the connecting part when the support structure is used later. In this way, the vibration isolation performance of the foot pad can be guaranteed after the limiting shim melts.

[0011] In some possible implementations, the thickness of the limiting gasket satisfies the following relationship: 2×H+0.1r1<T<3×H-0.2×R1; Wherein, T is the thickness of the limiting gasket, H is the distance between the connector and the foot pad in the axial direction of the connecting column, r1 is the maximum inner radius of the foot pad, and R1 is the radius of the portion of the connecting column that is fitted by the limiting gasket.

[0012] By ensuring that the thickness of the limiting shim satisfies the relationship 2×H+0.1r1<T<3×H-0.2×R1, the foot pad can obtain a more suitable compression amount. Under this compression amount, the foot pad is not easily deformed during the transportation of the support structure, nor is it easy for it to move axially in the connecting column. In this way, the axial impact load can be effectively reduced.

[0013] In some possible implementations, the inner ring radius of the limiting gasket is larger than the radius of the portion of the connecting post that is fitted by the limiting gasket.

[0014] By making the inner ring radius of the limiting shim larger than the radius of the part of the connecting column that is fitted by the limiting shim, it is easy to quickly fit the limiting shim and the connecting column together, thus improving the assembly efficiency of the support structure.

[0015] In some possible implementations, the inner ring radius of the limiting gasket satisfies the following relationship: 1.2×R1<R<1.5×R1; Wherein, R is the inner ring radius of the limiting gasket, and R1 is the radius of the portion of the connecting post that is fitted by the limiting gasket.

[0016] By ensuring that the inner ring radius of the limiting gasket satisfies the relationship 1.2×R1<R<1.5×R1, it is easy to quickly connect the limiting gasket and the connecting column, thus improving the assembly efficiency of the support structure.

[0017] In some possible implementations, the connector includes: a nut and a washer ring axially connected to the connecting post; the washer ring is closer to the limiting washer relative to the nut in the axial direction of the connecting post. Wherein, the outer ring radius of the limiting pad is less than or equal to the outer ring radius of the pad ring, and greater than the maximum inner radius of the foot pad.

[0018] By ensuring that the outer radius of the limiting shim is less than or equal to the outer radius of the shim ring, and greater than the maximum inner radius of the foot pad, sufficient contact area can be ensured between the limiting shim and the adjacent foot pad and shim ring. This reduces the probability of radial displacement of the limiting shim and the foot pad, thereby ensuring that the radial position between the various parts of the support structure does not easily change, which in turn ensures the effectiveness of the support structure.

[0019] In some possible implementations, the outer circumference of the limiting gasket satisfies the following relationship: 1.1×r1<r<1.4×r1; Where r is the outer circumference radius of the limiting pad, and r1 is the maximum inner radius of the foot pad.

[0020] By ensuring that the outer ring radius of the limiting shim satisfies the relationship 1.1×r1<r<1.4×r1, it is possible to more fully guarantee that the limiting shim has sufficient contact area with the adjacent foot pads and shim rings. In this way, the probability of radial displacement of the limiting shim and foot pads can be better reduced, thereby ensuring that the radial position between the various parts of the support structure is not easily changed, which in turn ensures the performance of the support structure.

[0021] In some possible implementations, the limiting gasket is a ring-shaped structure made of paraffin wax.

[0022] The limiting gasket is a ring-shaped structure made of paraffin wax, which makes it easy for the limiting gasket to melt when the temperature is higher than the preset temperature.

[0023] In some possible implementations, the limiting gasket is configured to melt at a temperature above 50°C.

[0024] The limiting gasket is configured to melt at temperatures above 50°C, facilitating the timely release of its limiting function.

[0025] In a second aspect, a compressor is provided, comprising: a compressor body, a foot, and a support structure; the foot is connected to the bottom of the compressor body and to a foot pad in the support structure; The supporting structure can be any of the supporting structures described above.

[0026] Thirdly, a household appliance is provided, including: a compressor as described above. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0030] As is well known, during transportation, the outdoor unit of an air conditioner is subjected to axial low-frequency loads below 50Hz from the road surface, and the compressor's rigid body mode is also within this load.

[0031] The outdoor unit of an air conditioner has piping connecting the compressor and the condenser, especially the piping directly connected to the compressor. During transportation, due to road bumps, the entire compressor may jump or swing, impacting the piping. If there are too many impacts, the piping may fatigue and break.

[0032] On the one hand, to address issues like excessive stress or fatigue fracture in transportation pipelines, research is conducted on the pipelines themselves, such as increasing their flexibility or length. Taking increasing pipeline flexibility as an example, multiple experiments are performed to determine the appropriate level of flexibility to mitigate pipeline fracture, followed by iterative testing of the pipeline's performance. While this approach can effectively reduce pipeline stress amplitude, it significantly increases experimental costs and severely impacts project schedules. Furthermore, it may also lead to excessive stress during pipeline operation.

[0033] On the other hand, a support structure is usually installed between the compressor's feet and the outdoor unit's chassis. This support structure provides fixation, vibration isolation, and cushioning protection. Within the support structure, rigid constraint components are installed between the foot pads and connectors to limit compressor sway, thereby reducing impact loads on the piping.

[0034] While this method can resolve issues like excessive stress or fatigue fracture in the transport piping, the limited internal space of the air conditioner increases the difficulty of installing rigid, hard-constrained components. In other words, using rigid, hard-constrained components presents a challenge in supporting structure installation. Furthermore, after the air conditioner is delivered to the customer, the installer must manually remove this structure. Removing rigid, hard-constrained components is also difficult and increases after-sales workload. Alternatively, if the installer forgets to remove the rigid, hard-constrained components, it will significantly impact the outdoor unit's NVH performance (Noise, Vibration, and Harshness), leading to noise complaints and other problems.

[0035] Therefore, this application provides a support structure that solves the problem of difficult assembly and disassembly of the support structure.

[0036] Figure 1 This is a schematic diagram of a support structure provided in an embodiment of this application. Please refer to it. Figure 1 In one embodiment of this application, a support structure 000 is provided, including: a connecting column 010, a foot pad 020, a limiting pad 030, and a connector 040.

[0037] Foot pad 020, limit pad 030 and connector 040 are all fitted onto connecting post 010, with foot pad 020 movably connected to connecting post 010 and connector 040 securely connected to connecting post 010.

[0038] In the axial direction of the connecting column 010, the limiting gasket 030 is located between the foot pad 020 and the connector 040, and the limiting gasket 030 is configured to melt after reaching a temperature higher than a preset temperature.

[0039] Understandably, since the limiting gasket 030 is a structure that can melt at temperatures above a preset level, its hardness will not be too high; that is, the limiting gasket 030 is a relatively soft structure. This relatively soft structure facilitates the installation of the limiting gasket 030. For example, the limiting gasket 030 can be placed in the space between the connector 040 and the foot pad 020 through compression, even in a narrow space. Alternatively, after the connector 040 and the connecting post 010 are securely connected, the limiting gasket 030 can be molded between the connector 040 and the foot pad 020.

[0040] In summary, using locating gaskets that melt at temperatures above a preset threshold facilitates installation. Since the locating gaskets fitted onto the connecting columns melt at these temperatures, disassembly is unnecessary, eliminating the need for disassembly and reducing the difficulty of assembling and removing the locating gaskets in the support structure. Furthermore, because the locating gaskets fitted onto the connecting columns melt at temperatures above the preset threshold, they are flexible structures. This allows the locating gaskets located between the foot pads and the connecting components to make soft contact with adjacent foot pads and connecting components, effectively reducing axial impact loads. Moreover, the foot pads in the support structure can be designed to be softer for better operational vibration isolation.

[0041] For example, foot pad 020 can be a rubber elastomer to facilitate vibration isolation.

[0042] Figure 2 This is a schematic diagram of another support structure provided in an embodiment of this application. Please refer to it. Figure 2 In some possible implementations, the thickness of the limiting pad 030 is greater than the distance between the foot pad 020 and the connector 040 before the connecting post 010 is compressed axially.

[0043] The thickness of the limiting shim 030 is greater than the distance between the foot pad 020 and the connector 040 before they are compressed axially in the connecting column 010. That is, the limiting shim 030 installed between the foot pad 020 and the connector 040 will keep the foot pad 020 in a compressed state. In this way, the probability of axial swaying of the support structure 000 can be better reduced during transportation, thus effectively reducing axial impact load.

[0044] In some possible implementations, the thickness of the limiting gasket 030 is greater than the amount of compression of the foot pad 020 in the axial direction of the connecting post 010.

[0045] Figure 3 This is a structural diagram of a support structure before and after installing a limiting gasket, provided in an embodiment of this application. Please refer to it. Figure 3,in, Figure 3 The left-hand diagram shows the structure of support structure 000 before the installation of the limiting pad 030. Figure 3 The diagram on the right side of the middle section is a schematic diagram of the structure after the support structure 000 is fitted with the limiting gasket 030.

[0046] Before the limit pad 030 is installed, there is a gap H between the foot pad 020 and the connector 040, and the foot pad 020 is in its original length state, that is, the foot pad 020 is not compressed.

[0047] After the limit shim 030 is installed, on the axial direction of the connecting column 010, the two sides of the limit shim 030 abut against the adjacent foot pad 020 and the connector 040 respectively. At this time, the foot pad 020 is in a compressed state with a certain amount of compression X, and the distance H between the foot pad 020 and the connector 040 increases.

[0048] By ensuring that the thickness T of the limiting shim 030 is greater than the axial compression X of the foot pad 020 on the connecting column 010, a gap H exists between the foot pad 020 and the connecting piece 040 before the limiting shim 030 is installed. This means that even after the supporting structure 000 is used and the limiting shim 030 melts, there will still be a certain gap H between the foot pad 020 and the connecting piece 040. This ensures the vibration isolation performance of the foot pad 020 after the limiting shim 030 melts.

[0049] It is understandable that the thickness T of the limiting gasket 030 can be equal to or slightly less than the sum of the compression X of the foot pad 020 in the axial direction of the connecting column 010 and the distance H between the foot pad 020 and the connector 040 before the limiting gasket 030 is installed, that is, T=X+H or T is less than X+H.

[0050] Please continue to refer to this. Figure 2 In some possible implementations, the thickness of the limiting gasket 030 satisfies the following relationship: 2×H+0.1r1<T<3×H-0.2×R1.

[0051] Where T is the thickness of the limiting gasket 030, H is the distance between the connecting piece 040 and the foot pad 020 in the axial direction of the connecting post 010, r1 is the maximum internal radius of the foot pad 020, and R1 is the radius of the part of the connecting post 010 that is fitted by the limiting gasket 030.

[0052] It should be noted that H refers to the distance between the connecting piece 040 and the foot pad 020 in the axial direction of the connecting column 010 before the limit shim 030 is installed.

[0053] Since the foot pad 020 is typically an elastic structure, such as an elastic rubber structure, if the compression of the foot pad 020 in the axial direction of the connecting column 010 is insufficient or inadequate, it is prone to shifting axially in the foot pad 020 during the transportation of the support structure 000. If the foot pad 020 can shift axially in the connecting column 010, it will affect the effect of reducing axial impact load.

[0054] This application achieves a more suitable compression amount for the foot pad 020 by ensuring that the thickness of the limiting shim 030 satisfies the relationship 2×H+0.1r1<T<3×H-0.2×R1. Under this compression amount, the foot pad 020 is less prone to deformation and axial movement during the transport of the support structure 000, thus effectively reducing axial impact load.

[0055] Figure 4 This is a schematic diagram of the structure of a limiting gasket provided in an embodiment of this application. Please refer to it. Figure 2 and Figure 4 In some possible implementations, the inner ring radius of the limiting gasket 030 is larger than the radius of the portion of the connecting post 010 that is fitted by the limiting gasket 030.

[0056] By making the inner ring radius of the limiting gasket 030 larger than the radius of the part of the connecting column 010 that is fitted by the limiting gasket 030, it is easy to quickly fit the limiting gasket 030 and the connecting column 010 together, thus improving the assembly efficiency of the support structure 000.

[0057] Please continue to refer to this. Figure 2 and Figure 4 In some possible implementations, the inner ring radius of the limiting gasket 030 satisfies the following relationship: 1.2×R1<R<1.5×R1.

[0058] Where R is the inner ring radius of the limiting gasket 030, and R1 is the radius of the part of the connecting post 010 that is fitted by the limiting gasket 030.

[0059] By ensuring that the inner ring radius of the limiting gasket 030 satisfies the relationship 1.2×R1<R<1.5×R1, it is easy to quickly connect the limiting gasket 030 and the connecting post 010, thereby improving the assembly efficiency of the support structure 000.

[0060] Figure 5 This is a schematic diagram of another support structure provided in the embodiments of this application. Please refer to it. Figure 5 In some possible implementations, the connector 040 includes a nut 041 and a washer ring 042 axially connected to the connecting post 010. In the axial direction of the connecting post 010, the washer ring 042 is closer to the limiting washer 030 relative to the nut 041.

[0061] Among them, the outer ring radius of the limiting gasket 030 is less than or equal to the outer ring radius of the gasket ring 042, and greater than the maximum inner radius of the foot pad 020.

[0062] By ensuring that the outer radius of the limiting shim 030 is less than or equal to the outer radius of the shim ring 042, and greater than the maximum inner radius of the foot pad 020, sufficient contact area can be ensured between the limiting shim 030 and the adjacent foot pad 020 and shim ring 042. This reduces the probability of radial displacement of the limiting shim 030 and the foot pad 020, thereby ensuring that the radial positions of the various parts of the support structure 000 do not easily change, thus ensuring the effectiveness of the support structure 000.

[0063] It should be noted that the nut 041 in connector 040 can be an integral part of the washer ring 042, or they can be two separate parts. When the nut 041 and washer ring 042 are two separate parts, they can be connected, for example, by welding, to achieve a fixed connection. Of course, the nut 041 and washer ring 042 can also be separate; in this case, the washer ring 042 is clamped and fixed by the axial force of the connecting post 010. No specific restrictions are imposed on the arrangement of the nut 041 and washer ring 042.

[0064] For example, in the embodiments of this application, the gasket ring 042 is an annular gasket with both the inner and outer rings being circular.

[0065] In addition, the annular gasket can also be square, triangular, polygonal, or other irregular shapes, and this application does not impose specific restrictions on this.

[0066] Please continue to refer to this. Figure 2 and Figure 4 In some possible implementations, the outer ring radius of the limiting gasket 030 satisfies the following formula: 1.1×r1<r<1.4×r1.

[0067] Where r is the outer ring radius of the limiting pad 030, and r1 is the maximum inner radius of the foot pad 020.

[0068] By ensuring that the outer ring radius of the limiting shim 030 satisfies the relationship 1.1×r1<r<1.4×r1, sufficient contact area can be guaranteed between the limiting shim 030 and the adjacent foot pad 020 and shim ring 042. This can better reduce the probability of radial offset of the limiting shim 030 and the foot pad 020, thereby ensuring that the radial position between the various parts of the support structure 000 is not easily changed, which also ensures the effectiveness of the support structure 000.

[0069] It can be understood that the compression of foot pad 020 in the axial direction of connecting post 010 can be limited by the relationship 2×H+0.1r1<T<3×H-0.2×R1, thus reducing the probability of foot pad 020 moving in the axial direction of connecting post 010. The radial position of foot pad 020 in connecting post 010 can be limited by the relationships 1.2×R1<R<1.5×R1 and 1.1×r1<r<1.4×r1, thus reducing the probability of foot pad 020 shifting radially in connecting post 010.

[0070] When the thickness T, inner diameter R, and outer diameter r of the limiting pad 030 simultaneously satisfy the corresponding relationship, the limiting effect on the foot pad 020 is optimal in this embodiment of the application, ensuring the stability of the transportation constraint, and thus better reducing the axial impact load during the transportation support structure 000.

[0071] For example, please refer to Figure 5 The connecting column 010 includes a column head 011, a column body 012, and a stud 013 connected sequentially along the axial direction of the connecting column 010.

[0072] The column head 011 is located on the side of the foot pad 020 opposite to the limiting washer 030, and the column head 011 abuts against the side of the foot pad 020 opposite to the limiting washer 030. The column body 012 passes through the through hole inside the foot pad 020 and extends into the limiting washer 030, that is, the limiting washer 030 and the foot pad 020 are sleeved and connected to the column body 012 in the column 010. The stud 013 is sleeved in the nut 041, and the nut 041 and the stud 013 are threaded together.

[0073] It is understandable that when the stud 013 passes through the limiting washer 030, it ensures that the limiting washer 030 can be firmly pressed onto the foot pad 020 after the nut 041 is turned to the limiting position or the set position.

[0074] In some possible implementations, when H is the distance between the connector 040 and the foot pad 020 in the axial direction of the connecting post 010, and H is 0, the thickness of the limiting gasket 030 is equal to the compression of the foot pad 020.

[0075] In some possible implementations, the limiting gasket 030 is a ring-shaped structure made of paraffin wax.

[0076] The limiting gasket 030 is a ring-shaped structure made of paraffin wax, which makes it easy for the limiting gasket 030 to melt when the temperature is higher than the preset temperature.

[0077] The limiting gasket 030 can be installed after the connector 040 and the connecting post 010 are securely connected. For example, liquid paraffin can be injected into the space between the foot pad 020 and the connector 040 using a mold, and the mold can be removed after the liquid paraffin has solidified. Alternatively, the limiting gasket 030 can be fixed to the gasket ring 042 in the connector 040 before the connector 040 is connected to the connecting post 010. This application does not impose specific restrictions on the setting method of the limiting gasket 030; it can be selected according to actual needs.

[0078] For example, the limiting gasket 030 is configured to melt at temperatures above 50°C.

[0079] For example, the limiting gasket 030 is configured to melt at a temperature of 50-70°C.

[0080] For example, the limiting gasket 030 is configured to melt at a temperature of 60°C.

[0081] The limiting gasket 030 is configured to melt at temperatures above 50°C, which facilitates the timely release of the limiting function of the limiting gasket 030.

[0082] Please continue to refer to this. Figure 5 In some possible implementations, the outer side of the foot pad 020 has a limiting groove 021 near the connector 040, which is used to engage with the foot 110.

[0083] For example, the foot pad 020 has a protruding ring 022 on the side of the limiting groove 021 facing the connector 040, and the radial dimension of the protruding ring 022 continuously increases from the side close to the connector 040 to the side away from the connector 040. In this way, it can guide the foot 110 and facilitate the engagement of the foot 110 and the limiting groove 021.

[0084] The limiting slot 021 ensures the connection stability between the support structure 000 and the machine foot 110, thereby better leveraging the function of the support structure 000. For example, the support structure 000 can provide support and vibration isolation.

[0085] In summary, using locating gaskets that melt at temperatures above a preset threshold facilitates installation. Since the locating gaskets fitted onto the connecting columns melt at these temperatures, disassembly is unnecessary, eliminating the need for disassembly and reducing the difficulty of assembling and removing the locating gaskets in the support structure. Furthermore, because the locating gaskets fitted onto the connecting columns melt at temperatures above the preset threshold, they are flexible structures. This allows the locating gaskets located between the foot pads and the connecting components to make soft contact with adjacent foot pads and connecting components, effectively reducing axial impact loads. Moreover, the foot pads in the support structure can be designed to be softer for better operational vibration isolation.

[0086] Figure 6 This is a schematic diagram of the structure of a compressor provided in an embodiment of this application. Please refer to it. Figure 6 In another embodiment of this application, a compressor 100 is provided, including: a compressor 100 body, a foot 110, and a support structure 000. The foot 110 is connected to the bottom of the compressor 100 body and to a foot pad 020 in the support structure 000.

[0087] Wherein, the support structure 000 is any of the support structures 000 described above.

[0088] The compressor 100 in this embodiment includes the support structure 000 in the above embodiment, which can effectively reduce the axial shaking of the compressor 100 during transportation. Also, when the compressor 100 is running normally, the limiting gasket 030 melts and flows out after the compressor 100 housing temperature reaches the preset temperature, thereby releasing the limiting effect and restoring the vibration isolation performance of the foot pad 020.

[0089] It should be noted that the compressor 100 in this embodiment can be applied to fields such as refrigeration and air conditioning, heat pump equipment, industry, and vehicles.

[0090] In another embodiment of this application, a household appliance is provided, including: a compressor 100 as described in the above embodiment.

[0091] Among them, home appliances include air conditioners, refrigerators, freezers, floor heating, water heaters, and other equipment.

[0092] The household appliance in this embodiment, including the compressor 100 described in the previous embodiment, can effectively reduce axial sway of the compressor 100 during transportation, reduce pipeline stress concentration, and thus reduce the risk of pipeline fatigue damage and breakage. It also automatically releases the limiting function after the compressor 100 casing temperature reaches a preset temperature during normal operation, restoring the vibration isolation performance of the foot pads 020, effectively improving the NVH performance of the outdoor unit.

[0093] For example, when an air conditioner is transported to a customer's home, the limit gasket 030 does not require the after-sales installation personnel to remove it a second time, which simplifies the after-sales work and improves after-sales efficiency.

[0094] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
