[0049] Refrigeration equipment (such as a refrigerator) has become one of the essential household appliances in people's family life, with the progress of science and technology and the improvement of living standards, users pay more and more attention to the use experience of the refrigeration equipment, in addition to the performance parameters of the refrigeration equipment, the noise size of the refrigeration equipment also gradually becomes the focus of attention. At present, although the refrigeration equipment has adopted the sound insulation cover plate, but the sound insulation effect of the sound insulation cover plate is still not significant, so that the refrigeration equipment still produces a large noise when working.

[0050] Therefore, in order to solve the technical problem that the sound insulation effect of the existing sound insulation cover plate 10 is not significant, with reference to Figures 1 to 4An embodiment of the utility model provides a sound insulation cover plate 10, this sound insulation cover plate 10 is used for refrigeration equipment (for example refrigerator). The sound insulation cover plate 10 includes plate body 100 and sound insulation block 200. Plate body 100 has the inner side wall 110 suitable for towards the inner cavity of refrigeration equipment. Since the main noise of refrigeration equipment originates from compressor and fan, and compressor and fan are usually installed in the compressor warehouse of refrigeration equipment, therefore the compressor warehouse noise is one of the main noise sound sources of refrigeration equipment. So in this embodiment, the above-mentioned inner cavity can include the compressor warehouse, at this time, the plate body 100 of sound insulation cover plate 10 is connected to the compressor warehouse to seal the compressor warehouse, so that the noise size of refrigeration equipment when working can be effectively reduced, guarantee refrigeration equipment can work quietly.

[0051] Sound insulation block 200 is connected to inner side wall 110 (for example, sound insulation block 200 can be welded to inner side wall 110), and sound insulation cavity 210 is arranged inside sound insulation block 200. That is, sound insulation block 200 is a hollow structure. Wherein, sound insulation block 200 is provided with opening 220 along the direction of one side of inner side wall 110, and opening 220 is communicated with sound insulation cavity 210. For example, sound insulation block 200 can be a single block structure, that is, sound insulation block 200 includes a plurality of side plates, and the plurality of side plates are collectively enclosed to form a semi-closed structure with opening 220. Sound insulation block 200 can only include one opening 220, and the opening 220 can be opened to the left, or the opening 220 can be opened to the right, so that the noise source is more easily propagated to the sound insulation cavity 210 through the opening 220. Sound insulation block 200 can include a plurality of openings 220, and one opening 220 can be opened to the left, and one opening 220 can be opened to the right, so that the noise source can be propagated to the sound insulation cavity 210 through the opening 220 from multiple directions. The sound insulation block 200 is arranged as a single block structure, which is beneficial to improve the structural strength and structural stability of the sound insulation block 200.

[0052] Or, for example, sound insulation block 200 can be a shell structure, and the sound insulation block 200 and the inner side wall 110 of the plate body 100 collectively enclose a semi-closed structure with the opening 220. Under this connection structure, the number and direction of the opening 220 can refer to the above description, which will not be repeated here.

[0053] Specifically, in the present embodiment, the mechanism in the inner cavity of the refrigeration equipment generates noise when working (for example, the compressor or the fan in the inner cavity of the refrigeration equipment generates noise when working), and the inner cavity is sealed by the sound-absorbing cover plate 10. On the one hand, the noise in the inner cavity is reflected on the inner side wall 110 of the plate body 100, the plate body 100 can change the propagation path of the noise and block the noise from propagating to the outside of the inner cavity; on the other hand, most of the noise in the inner cavity propagates into the sound-absorbing cavity 210 through the opening 220 (since the opening 220 is arranged on the side of the sound-absorbing block 200 along the direction parallel to the inner side wall 110, the noise is more likely to propagate into the sound-absorbing cavity 210 through the opening 220 after being reflected on the inner side wall 110), and the noise is reflected multiple times in the sound-absorbing cavity 210. In the process of multiple reflections, the noise is converted into internal energy and consumed, thereby reducing the noise radiated from the inner cavity to the outside; on the other hand, the air friction resistance in the inner cavity and the sound-absorbing cavity 210 can also consume the noise in the process of reflection, thereby further increasing the attenuation of the noise and improving the sound-absorbing effect.

[0054] In addition, by arranging the sound-absorbing block 200 on the inner side wall 110 of the plate body 100 (at this time, the sound-absorbing block 200 can be compared to a reinforcing rib), the torsional stiffness of the sound-absorbing cover plate 10 is increased, the structural strength of the sound-absorbing cover plate 10 is improved, and the service life of the sound-absorbing cover plate 10 is prolonged.

[0055] In some embodiments, with reference to Figures 1 to 4 The sound-absorbing block 200 includes a first side plate 231 arranged opposite to the opening 220, and the direction from the opening 220 to the first side plate 231 is a first direction X. Along the first direction X, the distance between the first side plate 231 and the inner side wall 110 gradually decreases. In other words, along the first direction X, the first side plate 231 is gradually inclined outward.

[0056] Specifically, in the present embodiment, along the direction in which the sound-absorbing block 200 points to the plate body 100, the projection area of the side of the sound-absorbing block 200 away from the plate body 100 on the inner side wall 110 is smaller than the projection area of the side of the sound-absorbing block 200 close to the plate body 100 on the inner side wall 110. With the above structure, on the one hand, the space of the inner cavity occupied by the side of the sound-absorbing block 200 away from the plate body 100 can be reduced, and the sound-absorbing block 200 can avoid compressing the space of the inner cavity, so that the mechanism in the inner cavity has enough space to dissipate heat when working; on the other hand, the size of the space in the sound-absorbing cavity 210 can be increased, thereby facilitating the extension of the reflection path of the noise in the sound-absorbing cavity 210, improving the conversion efficiency of the noise into internal energy, and ensuring the sound-absorbing effect of the sound-absorbing block 200.

[0057] In some embodiments, with reference to Figures 1 to 4The first side plate 231 is curved and extends along the first direction X from an end far away from the inner side wall 110 to an end close to the inner side wall 110.

[0058] Specifically, in the embodiment, the first side plate 231 is curved and extends, compared with the first side plate 231 extending in a straight line, on the one hand, since the first side plate 231 is irregularly shaped, it is beneficial to reduce the processing difficulty of the first side plate 231, facilitating the extrusion molding or injection molding of the first side plate 231; on the other hand, since the first side plate 231 is irregularly shaped, the inside of the sound attenuation block 200 will form an irregularly shaped sound attenuation cavity 210, when the noise propagates in the irregularly shaped sound attenuation cavity 210, the reflection frequency can be improved, and thus the conversion efficiency of the noise into internal energy can be improved, so that the noise gradually attenuates in the sound attenuation cavity 210.

[0059] In some embodiments, referring to Figures 1 to 4 , the direction perpendicular to the first direction X and parallel to the inner side wall 110 is the second direction Y, the sound attenuation block 200 comprises a second side plate 232 and a third side plate 233 arranged opposite along the second direction Y, and the second side plate 232 and the third side plate 233 are respectively connected to both sides of the first side plate 231 along the second direction Y. Along the direction from the second side plate 232 to the third side plate 233, the distance between the third side plate 233 and the inner side wall 110 gradually decreases; along the direction from the third side plate 233 to the second side plate 232, the distance between the second side plate 232 and the inner side wall 110 gradually decreases.

[0060] Specifically, referring to the structure of the first side plate 231 in the above-mentioned embodiments, along the direction from the sound attenuation block 200 to the plate body 100, the projection area of the side of the sound attenuation block 200 far away from the plate body 100 on the inner side wall 110 is smaller than the projection area of the side of the sound attenuation block 200 close to the plate body 100 on the inner side wall 110. With the above structure, the space of the inner cavity occupied by the side of the sound attenuation block 200 far away from the plate body 100 can be reduced, while the size of the space in the sound attenuation cavity 210 can be increased. Moreover, in the sound attenuation cavity 210, the noise can be reflected not only on the first side plate 231, but also on the second side plate 232 and the third side plate 233, thereby improving the reflection frequency and times of the noise in the sound attenuation cavity 210, to speed up the consumption of the noise in the sound attenuation cavity 210 and improve the conversion efficiency of the noise into internal energy.

[0061] In some embodiments, referring to Figures 1 to 4In the direction indicated by the second side plate 232 to the third side plate 233, the third side plate 233 extends in an arc shape from the end far away from the inner side wall 110 to the end close to the inner side wall 110. In the direction indicated by the third side plate 233 to the second side plate 232, the second side plate 232 extends in an arc shape from the end far away from the inner side wall 110 to the end close to the inner side wall 110.

[0062] Specifically, referring to the structure of the first side plate 231 in the above embodiment, the second side plate 232 and the third side plate 233 extend in an arc shape, compared with extending in a straight line, on the one hand, the processing difficulty of the second side plate 232 and the third side plate 233 can be reduced, and the processing efficiency of the second side plate 232 and the third side plate 233 can be improved; on the other hand, the reflection frequency and the reflection times of the noise in the sound attenuation cavity 210 can be improved, the conversion efficiency of the noise into internal energy can be accelerated, and the noise can be prevented from radiating to the outside of the sound attenuation cover plate 10.

[0063] In some embodiments, referring to Figures 1 to 4 The sound attenuation block 200 includes a fourth side plate 234, the fourth side plate 234 is an integral molding structure with the first side plate 231, the second side plate 232 and the third side plate 233, and the first side plate 231, the second side plate 232, the third side plate 233 and the fourth side plate 234 jointly form a convex shell 230 protruding in the direction away from the inner side wall 110, so as to form the sound attenuation cavity 210 in the sound attenuation block 200.

[0064] Specifically, in this embodiment, the noise can be reflected in the first side plate 231, the second side plate 232, the third side plate 233 and the fourth side plate 234 in the sound attenuation cavity 210, so as to facilitate improving the reflection frequency and the reflection times of the noise in the sound attenuation cavity 210, preventing the noise from propagating to the outside of the sound attenuation cover plate 10, and improving the sound attenuation effect of the sound attenuation cover plate 10. In addition, the first side plate 231, the second side plate 232, the third side plate 233 and the fourth side plate 234 adopt an integral molding process, which can reduce the processing difficulty of the sound attenuation block 200 and improve the structural strength of the sound attenuation block 200.

[0065] In some embodiments, referring to Figures 1 to 4 The sound attenuation block 200 includes a fifth side plate 240 and a convex shell 230 (for example, the convex shell 230 can include the first side plate 231, the second side plate 232, the third side plate 233 and the fourth side plate 234 in the above embodiment), the fifth side plate 240 and the convex shell 230 jointly define the sound attenuation cavity 210, and the fifth side plate 240 and the convex shell 230 can be an integral molding structure. The fifth side plate 240 is arranged in close contact with the inner side wall 110, and the convex shell 230 is arranged protruding in the direction away from the inner side wall 110.

[0066] Specifically, in the embodiment, the sound-absorbing block 200 is a single block structure, and the sound-absorbing block 200 has high overall strength and stability by adopting the above structure. The sound-absorbing block 200 can be welded to the inner side wall 110, and the fifth side plate 240 is used as the welding plane to realize the surface contact between the sound-absorbing block 200 and the inner side wall 110, thereby improving the welding strength between the sound-absorbing block 200 and the inner side wall 110 and preventing the sound-absorbing block 200 from falling off the inner side wall 110.

[0067] Alternatively, in other embodiments, the sound-absorbing block 200 includes a convex shell 230, which is arranged in a convex manner away from the inner side wall 110 and is connected to the inner side wall 110 to define the sound-absorbing cavity 210 together with the inner side wall 110.

[0068] Specifically, in the embodiment, the sound-absorbing block 200 is a shell structure, and the sound-absorbing block 200 can save manufacturing materials and reduce manufacturing costs by adopting the above structure. The sound-absorbing block 200 and the plate body 100 can be an integral molding structure, thereby shortening the production time of the sound-absorbing cover plate 10, improving the production efficiency of the sound-absorbing cover plate 10, and preventing material loss during the production of the sound-absorbing cover plate 10.

[0069] In some embodiments, the sound-absorbing cavity 210 is provided with a sound-absorbing filler (not shown in the figure). The sound-absorbing filler is a porous structure, for example, the sound-absorbing filler can be a structure made of polyurethane, or the sound-absorbing filler can be a structure made of glass wool, or the sound-absorbing filler can be a structure made of rock wool.

[0070] Specifically, in the embodiment, the sound-absorbing filler can effectively block and absorb the noise propagating into the sound-absorbing cavity 210, prevent the noise in the sound-absorbing cavity 210 from radiating outward, and increase the sound-absorbing effect of the sound-absorbing block 200. The sound-absorbing filler can partially fill the sound-absorbing cavity 210, improve the sound-absorbing effect of the sound-absorbing cover plate 10, and ensure that the sound-absorbing cover plate 10 has good heat dissipation performance. The sound-absorbing filler can also completely fill the sound-absorbing cavity 210, so that the noise propagating into the sound-absorbing cavity 210 can be completely absorbed by the sound-absorbing filler.

[0071] In some embodiments, referring to Figure 1 and Figure 3 , the sound-absorbing cover plate 10 includes a plurality of sound-absorbing blocks 200, and the plurality of sound-absorbing blocks 200 are arranged in a rectangular array. Each sound-absorbing block 200 is provided with an opening 220, and the openings 220 of the sound-absorbing blocks 200 have the same orientation to maintain the structural consistency of the sound-absorbing blocks 200.

[0072] Specifically, in the present embodiment, the plurality of sound-absorbing blocks 200 are uniformly distributed on the plate body 100. On the one hand, the noise generated in the inner cavity of the refrigeration equipment can be reflected into each sound-absorbing block 200 and continue to be reflected in each sound-absorbing block 200 until it is completely converted into internal energy, thereby reducing the radiation noise in the inner cavity. On the other hand, it is beneficial to improve the torsional stiffness of the sound-absorbing cover plate 10 and increase the structural strength of the sound-absorbing cover plate 10.

[0073] In some embodiments, with reference to Figure 3 The direction from the opening 220 to the first side plate 231 is a first direction X, and the direction perpendicular to the first direction X and parallel to the inner side wall 110 is a second direction Y. Along the first direction X, the interval distance L1 between the plurality of sound-absorbing blocks 200 satisfies: L1≤5mm; along the second direction Y, the interval distance L2 between the plurality of sound-absorbing blocks 200 satisfies: L2≥5mm. For example, the value of L1 can be 5mm, 4mm, 3mm, 2mm, 1mm, etc. The value of L2 can be 5mm, 6mm, 7mm, 8mm, 9mm, etc.

[0074] Specifically, in the present embodiment, the arrangement interval of the plurality of sound-absorbing blocks 200 in two directions is controlled to achieve better sound-absorbing effect. By setting the arrangement interval of the plurality of sound-absorbing blocks 200 within the above range, on the one hand, the plurality of sound-absorbing blocks 200 can be closely arranged, so that the sound-absorbing blocks 200 reflect and block the noise multiple times, thereby weakening the energy of the noise. On the other hand, the plurality of sound-absorbing blocks 200 can have sufficient noise propagation channels therebetween, avoiding the problem of sound wave resonance or accumulation due to too dense interval between the plurality of sound-absorbing blocks 200, so that the sound-absorbing blocks 200 can effectively consume and absorb the noise in different frequency ranges, thereby achieving the wide frequency design of the sound-absorbing cover plate 10 and achieving the purpose of improving the sound-absorbing performance.

[0075] In some embodiments, with reference to Figure 4 The length D1 of the sound-absorbing block 200 satisfies: D1≤20mm, the width D2 of the sound-absorbing block 200 satisfies: D2≤8mm, and the thickness D3 of the sound-absorbing block 200 satisfies: D3≤4mm. For example, the value of D1 can be 20mm, 15mm, 10mm, 5mm, etc. The value of D2 can be 8mm, 7mm, 6mm, 5mm, etc. The value of D3 can be 4mm, 3mm, 2mm, 1mm, etc.

[0076] Specifically, in the present embodiment, the length, width and thickness of the sound-absorbing block 200 are limited within the above range, which can limit the volume of the sound-absorbing block 200, avoid the sound-absorbing block 200 occupying too much space in the inner cavity, thereby being not conducive to the airflow in the inner cavity, causing the heat generated by the mechanism (such as the compressor) in the inner cavity to accumulate when working, and failing to effectively achieve the heat dissipation of the inner cavity.

[0077] It can be understood that the size of the sound attenuation block 200 (including at least one of the length, width and thickness of the sound attenuation block 200) should be adaptively set according to actual production needs, and the volume of the sound attenuation block 200 should not be set too small, otherwise the noise cannot be reflected multiple times in the sound attenuation cavity 210, which is not conducive to consuming and weakening the noise.

[0078] In some embodiments, with reference to Figures 1 to 3 The plate body 100 is provided with a heat dissipation through hole 120. For example, the heat dissipation through hole 120 can be oval, circular, square, etc., and the shape of the heat dissipation through hole 120 is not limited here.

[0079] Specifically, in the actual application, the inner cavity is installed with a mechanical structure such as a compressor, and corresponding to the normal projection area of the compressor on the inner side wall 110 in the direction of the compressor pointing to the plate body 100, the plate body 100 can be provided with a plurality of heat dissipation through holes 120. By using the above design, on the one hand, through the heat dissipation through hole 120, it is beneficial to the air circulation between the inner cavity and the external environment, realizing the convection heat exchange between the inner cavity and the external environment, so as to timely discharge the heat generated by the compressor during operation from the inner cavity, and avoid the heat accumulation in the inner cavity to affect the normal operation of the refrigeration equipment; on the other hand, it is beneficial to control the number of heat dissipation through holes 120 opened on the plate body 100, to prevent the noise generated by the compressor during operation from being directly transmitted to the outside of the inner cavity through the heat dissipation through hole 120, which is not conducive to the noise reduction of the refrigeration equipment.

[0080] Correspondingly, the utility model also provides another embodiment of a refrigeration equipment, which can be a refrigerator. The refrigeration equipment comprises the sound attenuation cover plate 10 in any of the above embodiments, and further comprises a shell, wherein the shell comprises a compressor compartment, the compressor compartment is provided with a compressor, and the sound attenuation cover plate 10 is connected to the shell to seal the compressor compartment. For example, the sound attenuation cover plate 10 can be provided with a first clamping part, the shell can be provided with a second clamping part, and the first clamping part and the second clamping part are matched with each other to clamp the sound attenuation cover plate 10 to the shell. In the above structure, the first clamping part can be a protrusion, and the second clamping part is a groove matched with the protrusion. Alternatively, the first clamping part can be a groove, and the second clamping part is a protrusion matched with the groove. For example, the sound attenuation cover plate 10 can be provided with a first magnetic attraction part, the shell can be provided with a second magnetic attraction part, and the first magnetic attraction part and the second magnetic attraction part are attracted to each other to magnetically attract the sound attenuation cover plate 10 to the shell. In the above structure, the sound attenuation cover plate 10 is convenient to install on the shell, or the sound attenuation cover plate 10 is convenient to detach from the shell.

[0081] Specifically, in the embodiment, the refrigeration equipment applying the above sound insulation cover plate 10 can reduce the noise radiated to the outside when the refrigeration equipment is working, and ensure that the refrigeration equipment can work quietly.

[0082] In some embodiments, the plate body 100 is provided with a heat dissipation plate close to one side of the compressor chamber, and the heat dissipation plate is opposite to the compressor.

[0083] Specifically, in the embodiment, corresponding to the area of the orthographic projection of the compressor on the inner side wall 110 in the direction from the compressor to the plate body 100, the plate body 100 can be provided with a heat dissipation plate with a corresponding size. By using the above design, on the one hand, the heat dissipation efficiency of the refrigeration equipment can be improved. When the compressor is working, the heat generated by the compressor can be directly conducted to the nearby heat dissipation plate, and then better and faster heat dissipation can be performed through the surface of the heat dissipation plate to reduce the temperature in the compressor chamber. In this way, the performance of the compressor can be prevented from being reduced or damaged due to overheating, the service life of the compressor is prolonged, the energy consumption is reduced, and the overall system efficiency is improved. On the other hand, the material consumption of the heat dissipation plate can be saved, and the production cost of the refrigeration equipment is reduced.

[0084] In some embodiments, the sound insulation cover plate 10 comprises a plurality of sound insulation blocks 200, and the plurality of sound insulation blocks 200 are arranged in a rectangular array. In the direction from the compressor to the sound insulation cover plate 10, the area surrounded by the plurality of sound insulation blocks 200 as a whole covers the projection of the compressor on the inner side wall 110 of the sound insulation cover plate 10. Preferably, the arrangement height of the sound insulation blocks 200 on the sound insulation cover plate 10 is greater than the height of the compressor in the compressor chamber, and the arrangement length of the sound insulation blocks 200 on the sound insulation cover plate 10 extends outward from one side of the compressor by a distance of not less than two compressor widths.

[0085] Specifically, in the embodiment, by arranging a plurality of sound insulation blocks 200 on the sound insulation cover plate 10, it can be ensured that the noise generated by the compressor when working is propagated into the sound insulation cavities 210 of the sound insulation blocks 200, so that the noise is converted into internal energy and consumed after being reflected in the sound insulation cavities 210 for multiple times. Therefore, the sound insulation and noise reduction performance of the sound insulation cover plate 10 is improved, and the refrigeration equipment can work quietly.

[0086] Thanks to the improvement of the above sound insulation cover plate 10, the refrigeration equipment of the embodiment has the same technical effects as the above sound insulation cover plate 10, which will not be described here.
