Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0048] At present, when the refrigeration equipment such as refrigerator and freezer is running, the compressor will generate a large noise pollution. In order to achieve the effect of noise reduction, the existing method is generally to attach sound-absorbing cotton on the outer cover of the compressor, but the noise reduction effect is still not ideal, which affects the user experience.

[0049] Therefore, the present application provides a compressor outer cover structure, by designing a back cavity space between the cover body and the sound-absorbing piece, the porous characteristics of the sound-absorbing piece itself can be utilized, combined with the back cavity space, the effect of resonance can be achieved, the sound energy can be dissipated, thereby expanding the frequency domain width of the sound-absorbing piece effect and optimizing the noise reduction performance.

[0050] In some embodiments, as shown in Figure 1 and Figure 2 The present application provides a compressor outer cover structure, which comprises a cover body 1 and a sound-absorbing piece 2. Wherein, the cover body 1 is provided with a back cavity 3 adjacent to one side of the compressor (not shown in the figure), the back cavity 3 is provided corresponding to the compressor, and the back cavity 3 is provided with an opening 4 adjacent to one side of the compressor; the sound-absorbing piece 2 covers the opening 4 and is used to contact the compressor.

[0051] Specifically, the inner side of the cover body 1 adjacent to the compressor can be provided with a plurality of side plates 5, and the plurality of side plates 5 are sequentially connected end to end, so as to enclose the back cavity 3 with an opening 4 on the cover body 1. This back cavity 3 can be located opposite to the compressor, so that the sound-absorbing piece 2 covering the opening 4 can be aligned and stably contacted with the compressor, thereby realizing the noise reduction of the compressor. Wherein, the side plate 5 and the cover body 1 can be an integral structure, which simplifies the assembly process and improves the overall structural strength and durability. Of course, the side plate 5 can also be installed on the cover body 1 by means of glue connection, screw connection and the like. Moreover, the specific shape of the back cavity 3 is not particularly limited, for example, it can be rectangular, hexagonal, circular and the like. In addition, the depth of the back cavity 3 can be 10mm, of course, it can also be other depths, which can be designed according to actual needs.

[0052] The sound absorbing member 2 is a component with a porous structure, and its main function is to absorb the energy of sound waves through its porous structure and convert the sound energy into heat energy. The sound absorbing member 2 can be a sound absorbing cotton, a sound absorbing board, etc. The sound absorbing cotton can be PU (polyurethane) cotton, green felt, and other cottons with porous properties. The sound absorbing board can be a mineral fiber sound absorbing board, a wood fiber sound absorbing board, and other boards with porous properties. The thickness of the sound absorbing member 2 can be 10 mm, but it can also be other thicknesses, which can be designed according to actual needs. The function of the sound absorbing member 2 is not only to block the propagation of noise, but more importantly, to work together with the back cavity 3 space to achieve more efficient dissipation of sound energy.

[0053] When the compressor operates and generates noise, since the sound absorbing member 2 is directly installed at the opening 4 of the back cavity 3 and in contact with the compressor, the sound waves will first contact the sound absorbing member 2 and then enter the inside of the back cavity 3 through the opening 4. The back cavity 3 is a relatively closed space, and the sound waves will undergo multiple reflections therein. These reflections will cause interference and resonance between the sound waves, which helps to increase the path length of the sound waves in the back cavity 3, so that the sound energy has more opportunities to be absorbed by the sound absorbing member 2 or converted into heat energy and dissipated.

[0054] It can be understood that traditional sound absorbing treatment is usually only effective for noise in a specific frequency range. However, by introducing the back cavity 3 structure, the application can broaden the effective frequency response range of the sound absorbing member 2, i.e., expand the frequency domain width of the sound absorbing member 2, by using the resonance effect. This means that it can more effectively suppress noise of different frequencies and provide more comprehensive noise reduction protection.

[0055] Therefore, the compressor cover structure provided by the embodiments of the application can effectively control the noise of the compressor by skillfully combining the sound absorbing member 2 and the back cavity 3 and using the resonance principle, thereby improving the user experience.

[0056] In some embodiments, referring to FIG. 1, the back cavity 3 includes at least two first cavities 6 with different depths. Figures 3 to 6

[0057] Specifically, the back cavity 3 is divided into cavities with different depths. Since sound waves will produce different resonance frequencies in cavities with different depths, this design can cover a wider frequency band.

[0058] It can be understood that since the noise of the compressor usually contains multiple frequency components, a single-depth back cavity 3 structure is difficult to cover comprehensively. Therefore, the application can reasonably design the first cavities 6 with corresponding depths according to the main noise frequency band of the compressor, so as to better adapt to the complex noise spectrum generated by the compressor, improve the overall noise reduction effect, and improve the user experience.

[0059] ​Therefore, the multi-depth back cavity 3 design of the embodiments of the present application can significantly expand the resonance frequency band width, thereby widening the noise reduction frequency range of the sound absorption piece 2 and achieving more efficient noise control.

[0060] In some embodiments, referring to Figure 3 and Figure 4 , at least one pad 7 is arranged in the back cavity 3 to form at least two first cavities 6 of different depths and in communication; and when there are at least two pads 7, the thicknesses of the pads 7 are different.

[0061] Specifically, the pads 7 of different thicknesses are arranged in the back cavity 3, so that the back cavity 3 is divided into multiple cavities of different depths and in communication. The pads 7 and the back cavity 3 can be an integrally formed structure or can be installed in the back cavity 3 by means of glue connection, screw connection, etc. For example, if one pad 7 is arranged, the back cavity 3 is divided into two cavities; if two pads 7 are arranged, the back cavity 3 is divided into three cavities, and so on. In one example, the pads 7 can be laid side by side along the length direction of the back cavity 3, thereby forming a stepped cavity structure of different depths.

[0062] Therefore, by arranging the pads 7 of different thicknesses, the embodiments of the present application can create multiple cavities of different depths, and each cavity corresponds to a different resonance frequency. This can significantly expand the resonance frequency band width, so that the entire structure can effectively absorb noise in a wider frequency range, improve the noise reduction performance, and thus improve the user experience.

[0063] In some embodiments, referring to Figure 5 and Figure 6 , a first partition plate 8 is arranged between adjacent first cavities 6.

[0064] Specifically, multiple first cavities 6 are arranged in the back cavity 3 and are separated by the first partition plate 8, which can ensure that each cavity works independently and avoids mutual interference, thereby enhancing the resonance intensity at a specific frequency.

[0065] Therefore, this design of the embodiments of the present application can enhance the resonance intensity in a specific frequency range, thereby improving the overall noise reduction effect.

[0066] In some embodiments, referring to Figure 7 , a first micro-perforated plate 9 is arranged in the back cavity 3 to divide the back cavity 3 into a second cavity 10 and a third cavity 11; and the first micro-perforated plate 9 is provided with multiple first through holes 12 that communicate the second cavity 10 and the third cavity 11, and the multiple first through holes 12 are distributed at intervals along the length direction of the first micro-perforated plate 9.

[0067] Specifically, the micro-perforated plate is a material with sound absorption and diffusion functions. The micro-perforated plate can be made of metal (such as galvanized steel plate, aluminum plate) or plastic and the like. Its surface is distributed with a large number of micro holes. The working principle of the micro-perforated plate is based on the friction and damping effect of sound waves when passing through the holes, which converts sound energy into heat energy, thereby achieving the effect of sound absorption.

[0068] The back cavity 3 is divided into two cavities, a second cavity 10 and a third cavity 11, by the first micro-perforated plate 9. A plurality of first through holes 12 are provided on the first micro-perforated plate 9 to communicate the second cavity 10 and the third cavity 11, and the through holes are distributed along the length direction of the first micro-perforated plate 9. When the sound wave enters the back cavity 3, part of the sound wave is absorbed by the first through holes 12 on the first micro-perforated plate 9, and the other part is reflected back and forth between the second cavity 10 and the third cavity 11 to dissipate the sound energy. This design allows the sound wave to pass between the two cavities, forming a complex sound wave propagation path, thereby increasing the resonance effect and sound absorption effect.

[0069] It can be understood that high-frequency (frequencies above 1000 Hz) sound waves are more easily affected by micro structures due to their shorter wavelengths, and therefore the micro first through holes 12 on the first micro-perforated plate 9 can effectively absorb high-frequency noise. Each through hole can be regarded as an independent small sound absorption unit, and the densely arranged through holes correspond to a combination of multiple sound absorption units. When high-frequency sound waves pass through these densely arranged through holes, they will undergo more absorption processes, thereby significantly increasing the frequency band width of high-frequency noise reduction, and enabling the structure to have better sound absorption performance in the high-frequency range.

[0070] Therefore, the embodiments of the present application significantly improve the overall noise reduction performance by combining multiple sound absorption mechanisms, especially in the case of handling high-frequency noise, which can significantly improve the noise problem during compressor operation and improve the user experience.

[0071] In some embodiments, referring to Figs. 1 to 3, the second cavity 10 corresponds to the opening 4, and the first closed plate 13 is arranged at the opening 4 to close the second cavity 10. Figure 8 and Figure 9 As shown in Figs. 1 to 3, the second cavity 10 corresponds to the opening 4, and the first closed plate 13 is arranged at the opening 4 to close the second cavity 10.

[0072] Specifically, the first closed plate 13 is installed at the opening 4 corresponding to the second cavity 10 to close the cavity, and the sound wave enters the third cavity 11 through the sound absorption piece 2, then enters the second cavity 10 through the first through holes 12 on the first micro-perforated plate 9, and the reflection and interference occur in the second cavity 10 and the third cavity 11, forming a resonance effect, further absorbing and dissipating sound energy. Such a design increases the complexity of the sound wave path, thereby enhancing the sound absorption effect.

[0073] In addition, the sound absorption effect of the first micro-perforated plate 9 can be optimized by adjusting parameters such as hole diameter, spacing, and plate thickness to meet the absorption requirements of different frequency bands of sound.

[0074] For example, the width W1 of the second cavity 10 is between 99 mm and 101 mm (for example, it can be 100 mm), the thickness of the first micro-perforated plate 9 is between 4.5 mm and 5.5 mm (for example, it can be 5 mm), the hole diameter of the first through hole 12 is between 8.5 mm and 9.5 mm (for example, it can be 9 mm), and the center distance between adjacent first through holes 12 is between 14.5 mm and 15.5 mm (for example, it can be 15 mm).

[0075] For another example, the width W1 of the second cavity 10 is between 64 mm and 66 mm (for example, it can be 65 mm), the thickness of the first micro-perforated plate 9 is between 4.5 mm and 5.5 mm (for example, it can be 5 mm), the hole diameter of the first through hole 12 is between 5.5 mm and 6.5 mm (for example, it can be 6 mm), and the center distance between adjacent first through holes 12 is between 14.5 mm and 15.5 mm (for example, it can be 15 mm).

[0076] By designing the relevant parameters of the first micro-perforated plate 9, the application can improve the resonance sound absorption and noise reduction effect of the entire structure in the 630 Hz frequency band (range is 600 Hz to 660 Hz).

[0077] In some embodiments, referring to FIGS. 1-3, Figure 10 and Figure 11 As shown, the first micro-perforated plate 9 is provided with two rows of first through holes 12 arranged along the height direction of the first micro-perforated plate 9, each row having a plurality of first through holes 12 spaced along the length direction of the first micro-perforated plate 9; and the second cavity 10 is provided with a second partition plate 14, which is arranged between the two rows of first through holes 12 to divide the second cavity 10 into a fourth cavity 15 and a fifth cavity 16, the fourth cavity 15 being in communication with the third cavity 11 through one row of first through holes 12, and the fifth cavity 16 being in communication with the third cavity 11 through the other row of first through holes 12.

[0078] Specifically, the second partition plate 14 is arranged inside the second cavity 10, so that the entire back cavity 3 can be further divided into three resonance sound absorption spaces, i.e., the third cavity 11, the fourth cavity 15, and the fifth cavity 16, each space corresponding to a different frequency. In addition, the first micro-perforated plate 9 is provided with two rows of first through holes 12, each row having a plurality of first through holes 12. The fourth cavity 15 is in communication with the third cavity 11 through one row of first through holes 12, and the fifth cavity 16 is in communication with the third cavity 11 through the other row of first through holes 12. This layout allows sound waves to be absorbed by the densely arranged plurality of first through holes 12 and enter the respective resonance sound absorption spaces through different paths for resonance, increasing the complexity of the sound wave propagation path and expanding the frequency band width of the sound absorption piece 2.

[0079] Therefore, the combination of the multiple sound absorption mechanisms can significantly improve the overall noise reduction performance, especially in the case of processing complex noise spectrum, which can significantly improve the noise problem during the operation of the compressor and improve the user experience.

[0080] Furthermore, by reasonably designing the aperture, pitch and plate thickness of the first micro-perforated plate 9, the resonance sound absorption performance of the entire structure in the 630Hz frequency band (range is 600Hz to 660Hz) can be enhanced. For example, the width W1 of the second cavity 10 is between 39mm and 41mm (for example, it can be 40mm), the thickness of the first micro-perforated plate 9 is between 4.5mm and 5.5mm (for example, it can be 5mm), the aperture of the first through hole 12 is between 3.5mm and 4.5mm (for example, it can be 4mm), the center distance between adjacent first through holes 12 is between 14.5mm and 15.5mm (for example, it can be 15mm), and the thickness of the second partition plate 14 is between 0.5mm and 1.5mm (for example, it can be 1mm).

[0081] In some embodiments, referring to Figure 12 and Figure 13 As shown, the back cavity 3 is provided with a second micro-perforated plate 17 and a second closed plate 18. The second micro-perforated plate 17 is separated in the back cavity 3, and the height of the second micro-perforated plate 17 is less than the depth of the back cavity 3. The second closed plate 18 is connected between the second micro-perforated plate 17 and the back cavity 3 to enclose a closed cavity 19 on one side in the back cavity 3, and the second closed plate 18 has a gap 20 with the sound absorption piece 2. The second micro-perforated plate 17 is provided with a plurality of second through holes 21 communicating the closed cavity 19 and the back cavity 3, and the plurality of second through holes 21 are distributed along the length direction of the second micro-perforated plate 17.

[0082] Specifically, by arranging the second micro-perforated plate 17 and the second closed plate 18 in the back cavity 3, three resonance sound absorption intervals can be formed, including the interval between the sound absorption piece 2 and the back cavity 3, the interval in the closed cavity 19 and the gap 20 interval between the sound absorption piece 2 and the second closed plate 18. Each interval can correspond to a different frequency, and each interval is connected. This layout allows sound waves to be absorbed by the densely arranged second through holes 21 and enter each resonance sound absorption interval through different paths for resonance, increasing the complexity of the sound wave propagation path and expanding the frequency band width of the sound absorption piece 2.

[0083] Therefore, the combination of the multiple sound absorption mechanisms can significantly improve the overall noise reduction performance, especially in the case of processing complex noise spectrum, which can significantly improve the noise problem during the operation of the compressor and improve the user experience.

[0084] In addition, by reasonably designing the parameters of the second micro-perforated plate 17, such as the hole diameter, the pitch and the plate thickness, the noise reduction performance of the whole structure in the frequency band of 630 Hz (ranging from 600 Hz to 660 Hz) can be ensured. For example, the width W2 of the closed cavity 19 is between 39 mm and 41 mm (for example, it can be 40 mm), the thickness of the second micro-perforated plate 17 is between 4.5 mm and 5.5 mm (for example, it can be 5 mm), the hole diameter of the second through hole 21 is between 3.5 mm and 4.5 mm (for example, it can be 4 mm), the center distance between adjacent second through holes 21 is between 14.5 mm and 15.5 mm (for example, it can be 15 mm), and the thickness of the second closed plate 18 is between 0.5 mm and 1.5 mm (for example, it can be 1 mm).
