Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air conditioning, and specifically provides an air conditioning outdoor unit and an air conditioner. Background Art
[0002] The compressor is a key component of an air conditioner's outdoor unit and a major source of vibration and noise. To reduce the impact of these vibrations and noise, traditional vibration isolation methods involve installing elastic pads or springs between the bottom wall of the outdoor unit's casing and the compressor. These elastic elements absorb and isolate the vibration energy generated by the compressor through their deformation properties, thereby reducing the impact of vibration on the air conditioning system and the surrounding environment.
[0003] Generally speaking, the lower the stiffness of an elastic element, the better its vibration isolation effect, because low-stiffness elastic materials can more effectively absorb and isolate vibration. However, reducing the stiffness of elastic elements can also cause some problems. For example, during the handling and transportation of air conditioner outdoor units, low-stiffness elastic pads may not effectively support the weight of the compressor, thereby increasing the vibration impact generated by the compressor. This impact may cause compressor piping to rupture and other structural damage. This problem is particularly prominent in large-displacement compressors, which are not only heavier but also require higher support and vibration reduction requirements. Pads that are too soft may not provide sufficient support and easily cause accidental damage to the equipment during transportation.
[0004] In view of this, a new technical solution is needed in this field to solve the above problems. Utility Model Content
[0005] The present application aims to solve the above technical problem, that is, to solve the problem of poor vibration reduction effect of the existing air conditioner outdoor unit.

[0035] Please refer to Figure 1 and 2 , is an air conditioner outdoor unit according to one embodiment of the present application. A support plate 12 is provided within the casing 1 of the air conditioner outdoor unit, and the compressor 2 assembly is mounted on the support plate 12. The support plate 12 is close to the bottom wall 11 of the casing 1, and a certain distance is left between the support plate 12 and the bottom wall 11 of the casing 1, thereby forming an interlayer space. A vibration damping assembly for buffering the vibration of the compressor 2 is disposed within this interlayer space.
[0036] Specifically, the interlayer space between the support plate 12 and the bottom wall 11 of the casing 1 not only provides physical isolation between the compressor 2 and the casing 1 to prevent the vibration of the compressor 2 from being directly transmitted to the casing 1, but also prevents the compressor 2 from directly impacting and wearing the casing 1 during operation.
[0037] Furthermore, the vibration-damping assembly provided in the interlayer space can absorb and disperse vibration energy, thereby reducing the impact of the vibration of the compressor 2 on the casing 1 .
[0038] Furthermore, the vibration damping assembly includes a first vibration damper 31 and a second vibration damper 32, which are respectively arranged at different positions of the support plate 12, and the first vibration damper 31 and the second vibration damper 32 are both arranged close to the compressor 2 to effectively reduce the intensity of vibration.
[0039] In one embodiment of the present application, reference Figure 3 The support plate 12 is provided with first through holes 121 at different positions, and the first vibration damping member 31 is installed in the first through holes 121 .
[0040] Specifically, refer to Figure 4 and 5 One end of the first vibration damper 31 is fixed to the first through hole 121 via the first clamping portion 311 to prevent the first vibration damper 31 from shifting or falling off. The installation process is relatively simple and easy to operate. The first clamping portion 311 is preferably in the form of a clamping protrusion. Of course, the specific structural form of the first clamping protrusion can be cylindrical, conical, square, a bar-shaped locking groove, a spring buckle, etc., as long as it can achieve a stable connection with the first through hole 121, and this application is not limited thereto.
[0041] The other end of the first vibration damper 31 abuts against the bottom wall 11 of the housing 1 .
[0042] Specifically, refer to Figure 4 The end of the first vibration damper 31 that contacts the bottom wall 11 of the casing 1 is flat. This flat surface ensures sufficient contact area between the first vibration damper 31 and the bottom wall 11, allowing the first vibration damper 31 to sit tightly and firmly on the bottom wall 11 of the casing 1. Furthermore, when subjected to vibration, the flat surface allows the first vibration damper 31 to absorb and disperse the vibration pressure on the support plate 12, thereby providing stable support and effective cushioning for the compressor 2 and enhancing the vibration reduction effect.
[0043] For the convenience of description, the end of the first vibration damper 31 connected to the support plate 12 is defined as the top end, and the end of the first vibration damper 31 abutting against the bottom wall 11 of the casing 1 is defined as the bottom end.
[0044] In one embodiment of the present application, a first elastic telescopic portion 312 is provided between the top and bottom ends of the first vibration damping member 31 , and the first elastic telescopic portion 312 includes a plurality of first buffer segments 313 connected in sequence.
[0045] The function of the first elastic expansion portion 312 is to increase the expansion or deformation of the first vibration damper 31 in the axial direction, so that the first vibration damper 31 has a greater expansion or deformation ability in the axial direction, effectively alleviating the vibration and noise caused by the operation of the air conditioner outdoor unit.
[0046] refer to Figure 4 The elastic expansion portion increases the expansion or deformation of the first vibration damping member 31 along the axial direction through a plurality of first buffer segments 313 connected in sequence.
[0047] Specifically, refer to Figure 5 The first buffer section 313 is divided into two connected parts, one part is an annular protrusion protruding outward from the outer circumference of the main body of the first vibration damper 31, and the other part is an annular recessed part recessed inward from the outer circumference of the main body. The two parts are connected in sequence to form a buffer section with a wave shape.
[0048] Compared to a simple straight-line structure, the wavy buffer structure has more surface area and deformation space. Within the same installation space, the wavy buffer structure can achieve greater expansion or deformation.
[0049] In one embodiment of the present application, a plurality of buffer cavities (not shown) are further provided in the main body of the first vibration damping member 31. The buffer cavities help provide deformation space for the first vibration damping member, thereby improving the buffering effect of the first vibration damping member.
[0050] Specifically, the buffer cavity can have a variety of structures. For example, it can be a circular hole, a strip-shaped hole, or a grid-like hole disposed within the first buffer component. Alternatively, the buffer cavity can be a through-hole structure extending axially through the main body, such as a circular hole, an elongated slot, or a spiral hole. This application does not impose any restrictions on the specific structure of the buffer cavity; any structure that can provide the necessary deformation space for the first buffer component and enhance its buffering effect is acceptable.
[0051] It can be seen from the above description that the structure of the first buffer member and the support plate 12 provides necessary support and buffering for the vibration of the compressor 2, effectively reducing the impact of the vibration of the compressor 2 on the air-conditioning system.
[0052] In one embodiment of the present application, reference Figure 6 and Figure 7 The two ends of the second vibration damper 32 are respectively connected to the support plate 12 and the bottom wall 11 of the housing 1. For the sake of convenience, the end of the second vibration damper 32 connected to the support plate 12 is defined as the first end, and the end of the second vibration damper 32 connected to the bottom wall 11 is defined as the second end.
[0053] Unlike the first vibration damper 31, the second vibration damper 32 has a support surface 321 at its first end. When the second vibration damper 32 is installed in the interlayer space, a gap 320 is formed between the support surface 321 and the support plate 12. This causes the support plate 12 to first compress the first vibration damper 31 when subjected to vibration. Only when the compression of the first vibration damper 31 reaches or exceeds the gap 320 between the support plate 12 and the support surface 321 does the support plate 12 contact the support surface 321, further compressing the second vibration damper 32.
[0054] Specifically, when the vibration amplitude of compressor 2 is small (e.g., vibration caused solely by the operation of compressor 2), first vibration damper 31 can independently provide the required cushioning. However, when the vibration amplitude is large (e.g., during transportation), first vibration damper 31 is compressed first, followed by support plate 12 contacting support surface 321 and further compressing second vibration damper 32, thereby achieving a stronger cushioning effect. This design allows the vibration damping system to flexibly adjust its cushioning capacity based on vibration intensity.
[0055] In one embodiment of the present application, the second vibration damper 32 has a stiffness greater than that of the first vibration damper 31 , that is, the second vibration damper 32 has a greater ability to resist elastic deformation than the first vibration damper 31 .
[0056] Specifically, since the first vibration damper 31 is used to cope with smaller vibration amplitudes, designing the stiffness of the first vibration damper 31 to be smaller helps to improve its sensitivity to vibrations with smaller amplitudes, thereby more effectively absorbing slight vibrations.
[0057] The second vibration damper 32 is used to cope with larger vibration amplitudes. The second vibration damper 32 is designed to have a larger stiffness. Relying on its strong ability to resist deformation, it can effectively cope with larger vibration amplitudes and provide strong buffering for the compressor 2, thereby reducing the impact and damage to other components in the system.
[0058] It can be seen that by using the first vibration damper 31 with lower stiffness in combination with the second vibration damper 32 with higher stiffness, the air conditioner outdoor unit can respond to vibrations of different intensities more flexibly and efficiently, which helps it maintain the stability of the system under different vibration conditions, thereby improving its durability and service life.
[0059] Of course, the support surface 321 can have various forms. For example, the support surface 321 can be directly provided on the end surface of the second end of the second vibration damper 32, or the second end can be provided with an annular groove, and the support surface 321 can be located on one of the end surfaces within the annular groove. In addition to the annular groove, grooves of other shapes can also be designed as the support surface 321. The specific form of the support surface 321 is not limited by this application.
[0060] In one embodiment of the present application, reference Figure 3 and Figure 7 The second damper 32 has a second engaging portion 322 at its first end. The support plate 12 has second through holes 122 at different locations. The second damper 32 is mounted in the second through holes 122 via the second engaging portions 322 to prevent displacement or removal of the second damper 32. The second engaging portion 322 has a similar structure to the first engaging portion and is preferably in the form of a protruding engaging portion.
[0061] The second end of the second vibration damping member 32 is also a flat surface similar to the bottom end of the first vibration damping member 31 , and the flat surface abuts against the bottom wall 11 of the housing 1 .
[0062] Furthermore, an annular groove is provided on the second clamping protrusion, and the supporting surface 321 is located on an end surface of the annular groove away from the supporting plate 12 .
[0063] In one embodiment of the present application, a second elastic telescopic portion 323 is provided between the first end and the second end of the second vibration damper 32. Similar to the function of the first elastic telescopic portion 312, its function is also to increase the axial expansion or deformation of the second vibration damper 32, thereby making the second vibration damper 32 have greater expansion or deformation ability in the axial direction.
[0064] In one embodiment of the present application, reference Figure 7The second vibration damper 32 is preferably a cylindrical component. The second elastic telescopic portion 323 is composed of a plurality of second buffer segments 3231 connected in sequence. The second buffer segment 3231 includes two connected parts, one of which is an annular protrusion protruding outward from the inner circumference of the cylindrical portion, and the other is an annular recessed portion recessed inward from the inner circumference of the cylindrical portion. These two parts are connected in sequence to form a buffer segment with a wave shape, similar to the first buffer segment 313 in the first vibration damper 31.
[0065] The wave-shaped buffer structure can achieve a larger expansion or deformation, which will not be described in detail here.
[0066] Furthermore, the cylindrical member has a third through hole 324 extending therethrough. A locking assembly 4 (e.g., a bolt, nut, and washer) is sequentially passed through the bottom wall 11 of the housing 1, the second vibration damper 32, and the support plate 12 to securely connect the three. This ensures that the support plate 12 and the second vibration damper 32 are stably connected and secured to the housing 1, thereby providing more stable support and cushioning during the vibration reduction process.
[0067] The present application also discloses an air conditioner, which includes an air conditioner outdoor unit in any of the above embodiments.
[0068] Because the air conditioner's outdoor unit provides relatively stable buffering for the vibrations generated by compressor 2 during operation and various vibrations during transportation, the air conditioner's use of this outdoor unit not only achieves significant results in controlling compressor 2 vibrations, but also demonstrates outstanding advantages in transportation safety and long-term operational stability. These features collectively constitute the core competitiveness of the air conditioning system, which boasts high performance and high reliability, giving it broad application prospects and significant competitive advantages in the market.
[0069] Thus far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
