Description

Sound insulation device and air conditioner

Technical Field

The application belongs to the technical field of household appliances, and particularly relates to a sound insulation device and an air conditioner.

Background

From a physiological point of view, any sound that interferes with people's rest, learning and work and with the sound that people want to hear, i.e. unwanted sounds, are collectively referred to as noise, and noise pollution is formed when noise adversely affects people and the surrounding environment. In real life, noise is ubiquitous, especially working noise of machinery, electric appliances and other devices, so that sound insulation measures are required for the noise sources to reduce noise pollution.

In the related art, for noise sources, an acoustic bag is generally adopted, that is, materials such as felt and rubber are wrapped around the noise source, so as to realize a large sound insulation amount. To achieve a greater amount of sound insulation, conventional solutions generally refer to mass law, which further increase the amount of sound insulation by increasing the thickness or weight of the acoustic bag. However, the acoustic bag cannot be too thick and the weight is limited due to the installation space and cost, so that it is difficult to further enhance the sound insulation effect.

Referring to fig. 1, an embodiment of the present application provides a sound insulation device 10 and an air conditioner, where the air conditioner includes the sound insulation device 10, and the air conditioner forms a refrigerant circulation system by using a compressor, an indoor heat exchanger, an outdoor heat exchanger, a throttling device, etc., and performs functions of refrigeration, heating, dehumidification, etc. by using circulation of refrigerant, so as to realize adjustment of indoor air, and provide a comfortable environment for indoor people. The compressor functions as a compression driving refrigerant in an air conditioning refrigerant circuit, and in operation, the compressor radiates noise outwardly through shell vibration, and the sound insulation device 10 is used to insulate and reduce noise of the compressor.

In the related art, for noise sources, an acoustic bag is generally adopted, that is, materials such as felt and rubber are wrapped around the noise source, so as to realize a large sound insulation amount. To achieve a greater amount of sound insulation, conventional solutions generally refer to mass law, which further increase the amount of sound insulation by increasing the thickness or weight of the acoustic bag. However, the acoustic bag cannot be too thick and the weight is limited due to the installation space and cost, so that it is difficult to further enhance the sound insulation effect.

In order to solve the problems in the related art, the sound insulation device 10 according to the embodiment of the present application includes the panel 100 and the sound absorption unit 200, and the sound absorption unit 200 is filled in the sound insulation cavity 110 of the panel 100, so that after noise is transmitted into the sound insulation cavity 110, the sound absorption unit 200 can absorb the noise, and since the sound absorption unit 200 includes the filling unit 210, the filling unit 210 includes the plurality of filling portions 211, and the plurality of filling portions 211 are sequentially arranged, each filling portion 211 can absorb the noise, so that the noise transmitted into the sound insulation cavity 110 can be absorbed for multiple times, and the sound insulation amount of the sound insulation device 10 is improved.

The application is described below with reference to specific embodiments in conjunction with the accompanying drawings:

Referring to fig. 1 and 2, an acoustic insulator 10 according to an embodiment of the present application is used for reducing noise of a noise source, and the acoustic insulator 10 includes a panel 100 and a sound absorbing unit 200. Wherein the panel 100 is a basic component of the sound insulation device 10 of the present application, the panel 100 may provide a mounting base for other at least partial components of the sound insulation device 10 and may also serve the purpose of protecting the other at least partial components of the sound insulation device 10. The panel 100 has a soundproof cavity 110, and the sound absorbing unit 200 is filled in the soundproof cavity 110, and the panel 100 may be made of polyurethane, rubber, aluminum plate, carbon fiber, etc., and the sound absorbing unit 200 is used to absorb noise.

The panel 100 may be connected to a noise source such that sound waves generated from the noise source may be transmitted into the soundproof cavity 110 through the panel 100 and absorbed by the sound absorbing unit 200. The sound absorbing unit 200 includes a filling unit 210, the filling unit 210 may be made of any conventional porous sound absorbing material, such as a conventional foam or honeycomb structure, and the filling unit 210 includes a plurality of filling portions 211, and the plurality of filling portions 211 are sequentially arranged, and each filling portion 211 can absorb noise, so that the noise introduced into the sound insulation cavity 110 can be absorbed for multiple times, and the sound insulation amount of the sound insulation device 10 is improved.

Referring to fig. 1 to 4, an incident sound wave 1 may be incident along one side of the panel 100, and is dissipated through the sound absorbing unit 200 in the sound insulating cavity 110 to be transmitted to the other side of the panel 100, thereby forming a transmitted sound wave 2, thereby achieving a sound insulating effect of the sound insulating device 10. When the performance of the plurality of filling portions 211 sequentially arranged in the sound insulation cavity 110 changes, evanescent waves 4 are generated after the incident sound waves 1 enter the sound insulation cavity 110 and are emitted along the direction of the reflected sound waves 3, so that the sound waves are mainly dissipated along two directions in the sound insulation cavity 110: absorption by the fill portion 211 and evanescent dissipation by the reflected back along the surface of the fill portion 211. That is, when the performance of the plurality of filling portions 211 is changed, evanescent dissipation of sound waves is increased, so that sound energy is more dissipated, and broadband sound insulation of the sound insulation device 10 is enhanced.

The variation of the performance of the plurality of filling portions 211 can be achieved by setting the sound-absorbing unit 200 to a periodic non-uniform structure in two ways: the heights of the plurality of filling portions 211 are different or the surface impedances of the plurality of filling portions 211 are different. Specifically, the height of the filling portion 211 is the height of the filling portion 211 in the transmission direction of sound, and the surface impedance of the filling portion 211 is related to the material of the filling portion 211 itself, i.e., the surface impedance of the plurality of filling portions 211 can be made different by providing filling portions 211 of different materials.

In some embodiments, at least two filling portions 211 have different heights in the transmission direction of sound, that is, by setting the filling portions 211 with different heights, performance of the filling portions 211 is changed, so that evanescent dissipation is generated by the sound wave.

The plurality of filling portions 211 may be sequentially arranged in a direction forming an angle with the transmission direction of the sound, and in particular, the arrangement direction of the plurality of filling portions 211 may be perpendicular to the transmission direction of the sound. The plurality of filling portions 211 may have two filling portions 211 with different heights, or the plurality of filling portions 211 may have different heights, and in consideration of the sound wave dissipation effect, the plurality of filling portions 211 in this embodiment have different heights. The plurality of filling portions 211 sequentially change in height in a direction forming an angle with the transmission direction of sound, and the heights of any adjacent two filling portions 211 are different.

Specifically, the height of the plurality of filling portions 211 may sequentially vary in one of a linear, an exponential, and a parabolic shape, and the height of the lowest point filling portion 211 may be 0.

In some embodiments, the panel 100 has opposite first and second sides, one of which of the first and second sides of the panel 100 may be coupled to a noise source such that noise generated by the noise source may pass through the panel 100 into the sound-deadening chamber 110. Of course, the sound-insulating cavity 110 also has a first side wall 111 and a second side wall 112 disposed opposite to each other, and the sound-absorbing unit 200 further includes a supporting portion 230, where the supporting portion 230 contacts the first side wall 111 and the second side wall 112, respectively, so that the supporting portion 230 can support the second side of the panel 100 when the first side of the panel 100 is connected to the noise source, and conversely, the supporting portion 230 can support the first side of the panel 100 when the second side of the panel 100 is connected to the noise source.

The height of the supporting portion 230 is greater than the height of any one of the filling portions 211, and the supporting portion 230 may be made of hard material to only support the supporting portion, or may be made of the same sound absorbing material as the filling portion 211, so that the supporting portion 230 can support the supporting portion and absorb noise at the same time.

Of course, in other embodiments, the sound absorbing unit 200 may be provided with no support portion 230 and only the filling portion 211, as shown in fig. 5, which is not limited in this example

As described above, by providing the filling portions 211 with different heights, the performance of the filling portions 211 may be changed, so that evanescent dissipation may be generated by the acoustic wave. Therefore, a space needs to be provided between the filling portion 211 and the first side wall 111 or the second side wall 112 of the acoustic cavity 110, so as to leave a transmission channel of the evanescent wave 4. Specifically, the filling portion 211 is disposed on the first side wall 111 of the acoustic isolation cavity 110 and is spaced from the second side wall 112 of the acoustic isolation cavity 110, so that a space between the filling portion 211 and the second side wall 112 of the acoustic isolation cavity 110 is a transmission channel of the evanescent wave 4.

Of course, the filling portion 211 may be disposed on the second side wall 112 of the acoustic isolation cavity 110 and spaced from the first side wall 111 of the acoustic isolation cavity 110, so that a space between the filling portion 211 and the first side wall 111 of the acoustic isolation cavity 110 is a transmission channel of the evanescent wave 4, which is not limited in this embodiment.

Referring to fig. 6, in some embodiments, the sound absorbing unit 200 includes two filling units 210, and the two filling units 210 are disposed opposite to each other and are disposed on the first sidewall 111 and the second sidewall 112 of the sound insulation cavity 110, so that the sound waves entering the sound insulation cavity 110 can be absorbed more, further enhancing the sound absorbing performance of the sandwich structure, and enhancing the sound insulation amount of the entire sound insulation device 10.

Specifically, the filling portions 211 of the two filling units 210 are oppositely arranged one by one, and the two filling portions 211 which are oppositely arranged are arranged at intervals, so that the sound absorbing unit 200 integrally forms a non-uniform intermittent structure, and therefore evanescent dissipation can be generated after sound waves enter the sound insulation cavity 110, and the height variation trend of the filling portions 211 of the two filling units 210 can be opposite, so that the intervals between the two filling portions 211 which are oppositely arranged are kept uniform, and the intervals are prevented from being too large or too small.

Referring to fig. 2, fig. 4 and fig. 5, the number of the sound-absorbing units 200 is plural, and the plurality of sound-absorbing units 200 are sequentially arranged in the sound-insulating cavity 110, so that the sound waves entering the sound-insulating cavity 110 can be absorbed by more sound-absorbing units 200, and more evanescent dissipation is generated, thereby improving the sound-insulating performance of the sound-insulating device 10.

In some embodiments, the sound-absorbing unit 200 has a plurality of filling channels 250 sequentially arranged, the filling channels 250 are arranged in the sound-insulating cavity 110, and the filling portions 211 are filled in the filling channels 250, so that after the sound waves are reflected by the filling portions 211, the sound waves are emitted along the filling channels 250, and evanescent dissipation is achieved. Specifically, the partition plates 240 may be disposed between adjacent filling portions 211, and the filling channels 250 are formed between adjacent partition plates 240, so that after the sound waves are reflected by the filling portions 211, the sound waves are emitted along the filling channels 250 under the isolation of the partition plates 240, and evanescent dissipation is achieved.

The acoustic isolation chamber 110 has oppositely disposed first and second sidewalls 111, 112, and a fill channel 250 extends from the first sidewall 111 to the second sidewall 112 and is spaced apart from the second sidewall 112 such that the spacing between the fill channel 250 and the second sidewall 112 is configured as a transmission channel for the evanescent wave 4.

As described above, the sound absorbing unit 200 includes two filling units 210, and the filling portions 211 of the two filling units 210 are disposed opposite to each other, so that the two filling portions 211 disposed opposite to each other can be disposed in the same filling channel 250, one filling portion 211 is connected to the first sidewall 111, and the other filling portion 211 is connected to the second sidewall 112, so that the two filling portions 211 are fixed. In one filling channel 250, two filling portions 211 are spaced apart so that the sound-absorbing unit 200 as a whole forms a non-uniform intermittent structure, and specifically, the spacing distances of the two filling portions 211 in the plurality of filling channels 250 may be the same.

Of course, in other embodiments, the surface impedance of each filling portion 211 may be modulated to achieve the performance change of the plurality of filling portions 211, that is, the plurality of filling portions 211 made of different materials are provided, which is not limited in this embodiment.

That is, in this embodiment, the sound absorbing unit 200 is configured to have a periodic non-uniform structure, so that the performance of the plurality of filling portions 211 is changed, thereby realizing evanescent dissipation of sound waves and enhancing broadband sound insulation of the sound insulation device 10. In addition to the increased dissipation of acoustic energy, however, the sound absorption unit 200 may be configured to absorb acoustic waves of different frequencies to enhance the broadband sound insulation of the sound insulation device 10.

Fig. 7 is a diagram showing the acoustic wave transmission loss corresponding to the different form of the acoustic insulator in the related art, and the abscissa in fig. 7 represents the acoustic wave frequency, the ordinate represents the acoustic wave transmission loss amount, the solid line represents the acoustic wave transmission loss when the acoustic insulator 110 is entirely filled with the acoustic absorbing material, and the circled solid line represents the acoustic wave transmission loss when the acoustic insulator 110 is not filled with the acoustic absorbing material. As shown in fig. 7, when the sound-deadening chamber 110 of the sound-deadening device 10 is filled with the sound-absorbing material, the sound-deadening amount of the sound wave at a low frequency can be increased, such as when the sound wave 2 is transmitted at 3, the sound wave frequency is 200-400 Hz. However, when the sound wave frequency is in the high frequency range, the sound-absorbing material is not filled in the sound-insulating chamber 110, and when only air is present, the sound-insulating amount is larger. The reason is that when the sound wave range is at a low frequency, the sound insulation amount of the sound insulation device 10 is mainly controlled by the quality, and by filling the inside with a sound absorbing material such as sound absorbing cotton, the quality of the entire sound insulation device 10 is improved, and the sound insulation amount thereof is improved; however, when the acoustic wave range is in a high frequency range, the acoustic wave can propagate along the solid frame in the acoustic material, resulting in a decrease in the sound insulation amount of the entire acoustic device 10, while in the air-filled scheme, the acoustic wave mainly propagates through the flow field, and the viscous force generated during the acoustic wave transmission is greatly increased in the high frequency range, so that the high frequency sound insulation amount of the acoustic device 10 is higher.

On this account, in order to enhance the sound insulation amount of the sound insulation device 10 in the entire wide frequency range from low frequency to high frequency, it is necessary to rationally design the structure of the sound absorption unit 200 in the sound insulation chamber 110. Referring to fig. 8, in some embodiments, a plurality of filling units 210 may be provided, the plurality of filling units 210 are sequentially arranged in the extending direction of the sound, the plurality of filling units 210 may be stacked, and the plurality of filling portions 211 of the same filling unit 210 are spaced apart to form a continuous periodic structure.

In this way, the quality of the entire soundproof apparatus 10 is improved due to the arrangement of the plurality of filling units 210, so that the sound insulation amount of the soundproof apparatus 10 can be ensured when the sound wave range is at a low frequency; since the plurality of filling portions 211 of the same filling unit 210 are arranged at intervals, and thus an air layer is provided between adjacent filling portions 211, when the acoustic wave range is at a high frequency, the acoustic wave can propagate through the flow field, and the sound insulation amount of the sound insulation device 10 is ensured when the acoustic wave range is at a high frequency. Therefore, the sound-absorbing unit 200 of this design can enhance the sound insulation of the sound-absorbing material at low frequencies and retain the sound insulation performance of the air layer at high frequencies.

The filler cells 210 of each layer may be made of different materials so that they may be optimally designed for different acoustic frequency bands. And the filling units 210 of each layer may include different numbers of filling parts 211, since the areas of the plurality of filling units 210 are substantially equivalent, that is, the area of the filling unit 210 is substantially the sectional area of the sound insulation cavity 110, when the number of filling parts 211 in one filling unit 210 is greater, the mass of the sound insulation device 10 is higher, the smaller the interval between adjacent filling parts 211 is, the smaller the air layer size is, so that the sound insulation device 10 has better sound insulation effect against low frequency sound waves; on the contrary, when the number of the filling portions 211 in one filling unit 210 is small, the mass of the sound insulation device 10 is small, the interval between the adjacent filling portions 211 is large, and the air layer size is large, so that the sound insulation device 10 has a good sound insulation effect against high-frequency sound waves, and the material of the filling unit 210 and the number of the filling portions 211 of each layer can be freely adjusted as required.

In some embodiments, the extending directions of the filling portions 211 of two adjacent filling units 210 are different, that is, the two adjacent filling units 210 may be disposed in a crossing manner, so as to increase the structural strength of the whole sound absorbing unit 200 and improve the sound-insulating effect of the sound-insulating device 10 in low-frequency sound waves. Specifically, two adjacent filler cells 210 may be disposed orthogonally or diagonally.

In some embodiments, the filling portions 211 may be elongated, specifically, the cross-section of the filling portion 211 may be rectangular, parallelogram, or waist-round, and correspondingly, the filling units 210 formed by the plurality of filling portions 211 at intervals may also be rectangular, parallelogram, and the like, and the extending directions of the plurality of filling portions 211 of the same filling unit 210 may be the same, that is, the plurality of filling portions 211 of the same filling unit 210 are arranged in parallel, and of course, the extending directions of the plurality of filling portions 211 of the same filling unit 210 may also be different, so as to ensure that the adjacent filling portions 211 have intervals therebetween.

Based on the same inventive concept, the embodiment of the application also provides an air conditioner, which comprises a compressor and the sound insulation device 10, wherein the compressor plays a role of compressing and driving a refrigerant in a refrigerant loop of the air conditioner, and the compressor has higher requirements on vibration noise characteristics while the functional performance meets the requirements of users. Vibration or noise created by the impingement of the exhaust fluid on the interior of the compressor is one of the primary sources of vibration noise within the compressor, which in operation radiates noise outwardly through shell vibration, i.e., the compressor may be the source of noise above. The sound insulation device 10 is used for sound insulation and noise reduction of the compressor.

The soundproof device 10 is connected to the compressor, specifically, the first side or the second side of the soundproof device 10 is connected to the compressor, so that vibration/noise generated from the compressor can be transmitted to the soundproof device 10, and thus the soundproof device 10 can perform soundproof and noise reduction on the compressor. The foregoing has described the beneficial effects of the sound insulation device 10 provided by the embodiment of the present application, and will not be described herein.

In some embodiments, the sound-insulating device 10 may be fixedly connected to the compressor by welding, bonding, or the like, which is not limited in this example.

In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention.
