Description

TECHNICAL FIELD

[0001] The present application belongs to the field of household appliances, and particularly relates to a damping assembly, a compressor and an air conditioner. BACKGROUND

[0002] With the improvement of people's living standards, more and more families use multi-split air conditioners (one outdoor unit drives multiple indoor units) and other air conditioners previously used in commercial applications. However, as consumers demand higher comfort levels for home appliances, the noise of home multi-split air conditioners is higher than that of general home air conditioners. Therefore, low-noise home multi-split air conditioners have become an inevitable trend in the development of multi-split air conditioners.

[0003] During operation of an air conditioning system, the main noise is composed of internal excitation and external excitation. The internal excitation refers to the noise caused by the vibration of the compressor (mainly the radiation of the motor) and the pipeline through the compressor mounting plate to the outdoor unit shell, causing the outdoor unit shell to vibrate and radiate noise outward. The external excitation refers to the noise caused by external forces (such as knocking) acting on the air conditioning system.

[0004] Currently, a rubber pad is usually assembled between the compressor mounting plate and the outdoor unit shell to reduce the vibration energy transmitted from the compressor and the pipeline to the shell and reduce the noise of the air conditioner. However, due to the complexity of the pipeline of the home multi-split air conditioning system and the large variation of the working conditions in different use scenarios, the complex frequency transmitted by the compressor is different. Therefore, it is difficult for the conventional damping washer to effectively reduce the noise of the air conditioner.

[0005] Therefore, the present application is proposed. SUMMARY

[0043] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "contact", "communication" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0044] At present, the conventional rubber pad is assembled between the compressor mounting plate and the outdoor unit shell to reduce the vibration energy transmitted from the compressor and pipeline to the shell and to reduce the air conditioner noise, but due to the complex pipeline of the household multi-connected machine system and the large change of working conditions in many use occasions, the complex frequency transmitted by the compressor is different, and the conventional rubber pad is difficult to effectively reduce the air conditioner noise.

[0045] To further illustrate the technical solutions in the present application, the following specific embodiments are provided in combination with the accompanying drawings. Figures 1-7

[0046] Embodiment 1

[0047] The damping assembly provided in the embodiments of the present application is as shown in Figure 1 The damping of the damping assembly can be adjusted to make the damping assembly generate a natural frequency different from the excitation frequency of the vibration body.

[0048] The damping of the damping assembly in the embodiments can be adjusted according to the excitation frequency of the vibration body to make the damping assembly generate a natural frequency different from the excitation frequency of the vibration body, so as to effectively prevent the vibration body from generating resonance.

[0049] Specifically, as shown in Figures 1-3 The damping assembly includes a rubber pad 1 and a foam metal damping layer 2, wherein the foam metal damping layer 2 includes at least one foam metal damping pad, and the damping of the damping assembly can be adjusted by changing the number of foam metal damping pads and / or the material of the foam metal damping pads and / or the pore gap of the foam metal damping pads to make the damping assembly generate a natural frequency different from the excitation frequency of the vibration body.

[0050] By using the combination design of the rubber pad and the foam metal damping layer 2 in the embodiments of the present application, the damping device can effectively absorb the impact and vibration energy of the system, improve the level of the damping assembly absorbing the impact and vibration energy, and play a role in damping and noise reduction.

[0051] ​Specifically, when damping the vibration body, the damping component can be adjusted in terms of the material of the foam metal damping pad (i.e. different materials with the same hole gap), the hole gap (i.e. the same material with different hole gaps), the combination of different parts (i.e. different materials with different hole gaps), and the number of damping pads (i.e. the same material, the same hole gap, and different numbers of foam metal damping pads) to change the damping of the damping component. The damping component with the corresponding damping can prevent the noise caused by the resonance of the vibration body and the damping component. In addition, the damping component in the embodiment of the present application can also absorb the energy of the external impact on the vibration body, reducing the influence of external excitation on the vibration body.

[0052] As described above, the foam metal damping layer 2 includes at least one foam metal damping pad.

[0053] When the foam metal damping layer 2 includes a plurality of foam metal damping pads, it includes an upper foam metal damping pad 21, a lower foam metal damping pad 22, and an additional foam metal damping pad stacked between the upper foam metal damping pad 21 and the lower foam metal damping pad 22. The additional foam metal damping pad is detachably mounted between the upper foam metal damping pad 21 and the lower foam metal damping pad 22. The additional foam metal damping pad can be selected to be stacked between the upper foam metal damping pad 21 and the lower foam metal damping pad 22 according to the excitation frequency of the vibration body. That is, by adding one or more layers of foam metal damping pads between the upper foam metal damping pad 21 and the lower foam metal damping pad 22, the damping of the damping component can be quickly changed, and the damping component matched with the vibration body can be accurately designed to make the natural frequency of the vibration body system and the excitation frequency staggered, which can effectively prevent resonance problems.

[0054] Specifically, when the foam metal damping pad is provided with a plurality of foam metal damping pads, a convex is arranged on the top of the upper foam metal damping pad 21, and a groove matching the convex is arranged on the bottom of the rubber pad 1. The upper foam metal damping pad 21 and the rubber pad 1 are matched by convex and concave, so as to connect the foam metal damping layer 2 and the rubber pad 1 together.

[0055] It is worth noting that when the foam metal damping pad in the foam metal damping layer 2 is provided with a plurality of foam metal damping pads, the damping of the damping component can be adjusted by changing the number of foam metal damping pads and / or the material of the foam metal damping pad and / or the hole gap of the foam metal damping pad to make the damping component have a natural frequency different from the excitation frequency of the vibration body, thereby preventing resonance problems.

[0056] Of course, in some alternative embodiments, the foam metal damping layer 2 can be provided with only one foam metal damping pad, and when the foam metal damping layer 2 is provided with only one foam metal damping pad, a convex is arranged on the top of the foam metal damping pad, and a groove matching the convex is arranged on the bottom of the rubber pad 1, and the foam metal damping pad is matched with the rubber pad 1.

[0057] It should be noted that when the foam metal damping layer 2 is provided with only one foam metal damping pad, the natural frequency of the vibration body system and the excitation frequency can be offset by changing the material or the pore gap of the foam metal damping pad, so as to prevent the resonance problem from occurring.

[0058] It should be noted that through the modal knock experiment, it can be found that the material hardness T of the foam metal damping pad is in a positive proportional relationship with the natural frequency of the damping assembly, and the pore gap Q of the foam metal damping pad is in an inverse proportional relationship with the natural frequency of the damping assembly.

[0059] In any of the above embodiments, as shown in Figures 1-3 , the damping assembly further comprises a damping sheath 3, the foam metal damping layer 2 is sleeved in the damping sheath 3, and the rubber pad 1 is installed on the top of the foam metal damping layer 2 and is configured to be connected with the vibration body, and when the foam metal damping layer 2 is placed in the damping sheath 2, the rubber pad 1 at least partially protrudes outside the damping sheath, so as to facilitate the connection between the rubber pad 1 and the vibration body.

[0060] Specifically, as shown in Figure 3 , the above-mentioned damping sheath 3 is also made of foam metal, and the damping sheath 3 is also made of foam metal, so as to further improve the damping effect of the damping assembly.

[0061] More specifically, when the foam metal damping layer 2 is provided with a plurality of foam metal damping pads, in order to make the height of the damping assembly moderate, as shown in Figure 3 , the thickness of the upper foam metal damping pad 21 is set to be between 2mm and 5mm, and preferably, the thickness of the upper foam metal damping pad 21 is 3.5mm.

[0062] The thickness of the lower foam metal damping pad 22 is set to be between 3mm and 7mm, and preferably, the thickness of the lower foam metal damping pad 22 is 5.5mm.

[0063] The thickness of the additional layer of foam metal damping pad is set to be between 1mm and 3mm, and preferably, the thickness of the additional layer of foam metal damping pad is set to be 2mm.

[0064] The thickness of the additional layer of foam metal damping pad is set to be between 1mm and 3mm, and preferably, the thickness of the additional layer of foam metal damping pad is set to be 2mm.

[0065] The thickness F of the shock-absorbing sheath 3 is set between 2mm and 4mm, preferably 3mm.

[0066] In addition, as shown in Figures 1-3 In order to fix the position of the foam metal shock-absorbing pad and the rubber sleeve, the shock-absorbing sheath 1 is set as a cylindrical sleeve with an opening at the top in the embodiment, wherein the foam metal shock-absorbing pad is a circular shock-absorbing pad embedded in the shock-absorbing sheath 3, and the outer wall surface of the foam metal shock-absorbing pad abuts against the inner wall surface of the shock-absorbing sheath 3 when the foam metal shock-absorbing pad is placed in the shock-absorbing sheath 3, thereby avoiding the foam metal shock-absorbing pad installed in the shock-absorbing sheath 3 from moving and improving the overall stability of the shock-absorbing assembly.

[0067] In any of the above embodiments, the shock-absorbing assembly comprises the shock-absorbing sheath 3, the upper foam metal shock-absorbing pad 21, the lower foam metal shock-absorbing pad 22 and the rubber pad 1, wherein the shock-absorbing sheath 3 is a cylindrical foam metal sleeve with an opening at the top, the upper foam metal shock-absorbing pad 21 and the lower foam metal shock-absorbing pad 22 are circular pads, and when the shock-absorbing assembly is installed, the lower foam metal shock-absorbing pad 22 is embedded at the bottom of the shock-absorbing sheath 3, the outer circumferential wall of the lower foam metal shock-absorbing pad 22 tightly abuts against the inner circumferential wall of the shock-absorbing sheath 3, and the upper foam metal shock-absorbing pad 21 is stacked on the upper end of the lower foam metal shock-absorbing pad 22 and the upper end of the upper foam metal shock-absorbing pad 21 further forms a convex, which is a cylindrical convex.

[0068] The bottom of the rubber pad 1 is provided with a circular through slot, and when the rubber pad 1 is installed, the rubber pad 1 is nested in the shock-absorbing sheath 3 and is inserted on the upper foam metal shock-absorbing pad 21 through the through slot at the bottom of the rubber pad 1, and the convex at the upper end of the upper foam metal shock-absorbing pad 21 is inserted in the through slot on the rubber pad 1 to fix the position of the rubber pad 1. It is worth noting that the rubber pad is a conical rubber pad, and when the rubber pad 1 is installed, the outer circumferential surface at the bottom of the rubber pad 1 also tightly abuts against the inner circumferential surface of the shock-absorbing sheath 3.

[0069] After the rubber pad 1 is installed, the shock-absorbing sheath 3 is fixed on the base through screws, one end of the screws is fixed on the base, the other end of the screws passes through the shock-absorbing sheath 3 and is connected with the lower foam metal shock-absorbing pad 22, wherein the bottom of the vibration body is provided with a supporting leg, and the vibration body is fixedly installed on the rubber pad 1 through the supporting leg, thereby realizing the shock-absorbing effect of the shock-absorbing assembly on the vibration body.

[0070] On the other hand, the embodiment of the present application further provides a compressor as shown in Figure 4 The compressor comprises a compressor body 4, a supporting leg 41 and the above-mentioned shock-absorbing assembly, wherein the supporting leg is an L-shaped supporting leg, one end of the supporting leg is connected to the bottom of the compressor body 4, and the other end of the supporting leg is connected to the shock-absorbing assembly. Specifically, the supporting leg 41 of the compressor body 4 is sleeved on the outside of the rubber pad 1.

[0071] In still another aspect, the present application also provides an air conditioner comprising the above-mentioned compressor.

[0072] The following will be described in detail with the example that the damping assembly is installed on the compressor body 4:

[0073] When the compressor is provided with the damping assembly, the L-shaped leg of the compressor is only needed to be placed on the rubber pad 1 of the damping assembly for use.

[0074] The damping assembly is used for improvement when the actual system is matched or the noise abnormality caused by the system fixed frequency change after sale occurs.

[0075] For example, the 62HZ six times frequency problem occurs when the compressor system is matched, the modal modal knocking fixed frequency of the leg 41 and the damping assembly is about 360Hz, which is just corresponding to cause the six times frequency noise. At this time, another layer of additional layer of foam metal damping pad can be added in the upper layer of foam metal damping pad 21 and the lower layer of foam metal damping pad 22, so as to increase the modal of the leg 41 and the damping assembly to avoid the 360Hz resonance. The assembly mode can not only be adjusted at any time and anywhere, but also can be quickly identified, which saves the cost and provides a fast and convenient channel for development and after-sales.

[0076] Of course, the material of the foam metal damping pad in the damping assembly (i.e. the same hole gap and different materials), the hole gap (i.e. the same material and different hole gaps), and the combination adjustment between different parts (different materials and different hole gaps) can be adjusted, the damping of the damping assembly is changed, the air conditioning system is developed, the corresponding damping damping assembly is accurately designed according to the system resonance point, and the resonance of the outdoor machine shell, the compressor and the air conditioning pipeline is effectively prevented.

[0077] For example, Figures 5-7 The test results of different combinations of the damping assembly, i.e. the influence of the change of the natural frequency on the system noise vibration.

[0078] For example, formula one: the upper layer of foam metal damping pad 21 adopts the foam nickel with a hole gap of 10 wires, the lower layer of foam metal damping pad 22 adopts the foam copper with a hole gap of 20 wires, and the damping sheath 3 adopts the foam aluminum with a hole gap of 10 wires;

[0079] For example, formula two: the upper layer of foam metal damping pad 21 adopts the foam lead with a hole gap of 10 wires, the lower layer of foam metal damping pad 22 adopts the foam zinc with a hole gap of 20 wires, and the damping sheath 3 adopts the foam steel with a hole gap of 10 wires;

[0080] For example, formula three: the same material as formula one but the hole gap is 5 wires larger than formula one; and the like, which is not limited to the above solutions.

[0081] It can be seen that the damping assembly with adjustable inherent frequency is arranged in the embodiment of the application, so that the exciting frequency of the air conditioning system is not coincident with the inherent frequency, and the resonance of the air conditioning outer casing, the compressor and the air conditioning pipeline is effectively prevented.

[0082] As Figure 6 and Figure 7 For the test results of the peak values of the twice frequency and six times frequency noises of each combination mode, the damping assembly matched with the system can be selected.

[0083] In summary, the inherent frequency of the damping assembly can be adjusted by adjusting the material, the inter-pore gap and the number of layers of the foam metal damping pad, the resonance of the system is adjusted, the noise and vibration of the air conditioning system are reduced, and the influence of the external excitation on the air conditioning system is weakened.

[0084] The above merely describes the preferred embodiments of the application and is not intended to limit the application in any form. Although the application has been disclosed as above with the preferred embodiments, the application is not intended to be limited thereto. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the application, and any simple modification, equivalent change and modification of the above-mentioned embodiments based on the technical essence of the application are still within the scope of the application.
