DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments (or, the implementation manners) of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0041] If the application embodiments involve directional indications or positional relationships (such as up, down, left, right, front, back, inner, outer, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings); if the specific posture changes, the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.

[0042] ​​​With the development of social economy and the improvement of people's living standards, the refrigerator gradually becomes an indispensable household appliance in people's daily life, and people's requirements for the refrigerator are also gradually improved. In addition to paying attention to the functional diversity of the refrigerator and the beauty of the appearance, people also have higher and higher requirements for the low noise of the refrigerator during operation.

[0043] In the related art, in order to reduce the noise generated by the refrigerator during operation, a sound insulation and noise reduction part is usually arranged on the refrigerator to absorb the noise generated by the refrigerator during operation, so as to realize low noise operation of the refrigerator. However, the sound absorption and sound insulation effect of the current sound insulation and noise reduction part is poor.

[0044] Based on this, as shown in Figures 1 to 5 , a noise reduction part 120 and a refrigerator 10 are provided, the noise reduction part 120 has good sound absorption and sound insulation effect, which is beneficial to reduce the noise generated by the refrigerator 10 during operation, so as to improve the user experience of the refrigerator 10.

[0045] As shown in Figure 5 and Figure 6 , a noise reduction part 120 is provided, the noise reduction part 120 includes a mounting wall 121 and a first side wall 122, and the noise reduction part 120 can be installed through the mounting wall 121. The first side wall 122 is arranged adjacent to the mounting wall 121. The first side wall 122 is provided with a plurality of noise reduction channels 123, and the plurality of noise reduction channels 123 are arranged at intervals. One end of the noise reduction channel 123 is in communication with the outside, and the other end is closed.

[0046] In this way, when the noise reduction part 120 is assembled, the noise reduction part 120 can be installed on the refrigerator 10 through the mounting wall 121. And a plurality of noise reduction channels 123 are opened on the first side wall 122, when the noise is transmitted to the noise reduction part 120, on the one hand, the noise reduction part 120 is used to isolate the noise from the outside, so as to avoid the noise from being transmitted to the outside. On the other hand, the noise can enter the noise reduction channel 123, and the closed setting of one end of the noise reduction channel 123 makes the noise in the noise reduction channel 123 propagate in the closed channel, and the sound wave energy is absorbed or reflected by the wall of the noise reduction channel 123, so as to weaken the noise intensity. The noise reduction part 120 has good noise reduction effect, which is beneficial to improve the user experience.

[0047] It should be noted that the specific implementation mode of the noise reduction part 120 can be various, including one-piece manufacturing and split manufacturing and reassembly.

[0048] It should be noted that the specific implementation mode of the forming process of the noise reduction part 120 can be various, including but not limited to co-extrusion process, mold pressing process and injection molding process, etc.

[0049] As shown in Figures 1 to 3As shown, a refrigerator 10 is also provided, the refrigerator 10 comprising a cabinet assembly 200 and the noise reduction member 120 in the above embodiments. The cabinet assembly 200 comprises a machine compartment 210, which is located at the bottom of the cabinet assembly 200, and the noise reduction member 120 is arranged in the machine compartment 210.

[0050] In some embodiments, the machine compartment 210 of the refrigerator 10 is adhesively fixed with the noise reduction member 120. In this way, this method is easy to implement and simple to realize.

[0051] As Figure 1 and Figure 2 As shown, in some embodiments, the refrigerator 10 further comprises a refrigeration device 300, which is arranged in the machine compartment 210.

[0052] In this way, when the refrigerator 10 is in operation, the refrigeration device 300 in the machine compartment 210 of the refrigerator 10 is started to provide the refrigerator 10 with refrigeration function. The noise reduction member 120 is arranged in the machine compartment 210 through the mounting wall 121, and when the refrigeration device 300 in the machine compartment 210 is in operation, the noise generated by the refrigeration device 300 can be transmitted to the noise reduction member 120. When the noise is transmitted to the noise reduction member 120, on the one hand, the noise reduction member 120 is used to isolate the noise from the outside world, so as to avoid the noise from being transmitted to the outside world. On the other hand, the noise can enter the noise reduction passage 123, and the noise in the noise reduction passage 123 is absorbed or reflected by the inner wall of the noise reduction passage 123 when it propagates in the closed passage, so as to weaken the noise intensity. The refrigerator 10 applies the noise reduction member 120 in any of the above embodiments, and the noise reduction member 120 has good effect, which is conducive to improving the user's experience of using the refrigerator 10.

[0053] In some embodiments, the refrigeration device 300 comprises a compressor 310 and a cooling fan 320, which are arranged in the machine compartment 210. In this way, when the compressor 310 is in operation, the cooling fan 320 can help dissipate the heat generated by the compressor 310 when it is in operation, prevent the compressor 310 from overheating, and ensure the normal operation of the compressor 310.

[0054] As Figure 1 and Figure 2As shown, in some embodiments, the refrigerator 10 further includes a door assembly 110, which is movably connected to the body assembly 200. The body assembly 200 has at least one storage cavity 220, which is spaced apart from the compressor compartment 210, and the compressor compartment 210 is located at the bottom of the body assembly 200. Thus, the door assembly 110 is movably connected to the body assembly 200 to open or close the storage cavity 220. When the refrigerator 10 is operating, the compressor 310 in the compressor compartment 210 starts to cool the storage cavity 220, providing a refrigeration and freezing environment for the items inside the storage cavity 220, which is beneficial for the storage of the items inside the storage cavity 220.

[0055] like Figures 7 to 9 As shown, in some embodiments, the depths between at least two of the noise reduction channels 123 are unequal. Thus, researchers have found in experiments that different depths of the noise reduction channels 123 can reduce noise at different frequencies. By providing multiple noise reduction channels 123 in the noise reduction device 120 and ensuring that the depths between at least two noise reduction channels 123 are unequal, noise at different frequencies can be reduced more effectively, thereby further improving the noise reduction effect of the noise reduction device 120.

[0056] It should be noted that the unequal depth between at least two noise reduction channels 123 can mean that the noise reduction device 120 includes several noise reduction channels 123, of which at least two noise reduction channels 123 have unequal depths, and there are noise reduction channels 123 with equal depths. Alternatively, it can mean that the depths of several noise reduction channels 123 are all unequal.

[0057] In some embodiments, the inner wall of the noise reduction channel 123 is provided with protrusions. Thus, when the refrigerator 10 is working, when its noise is transmitted to the noise reduction channel 123, the protrusions on the inner wall of the noise reduction channel 123 can further reduce noise, thereby improving the noise reduction effect of the noise reduction component 120.

[0058] Of course, in other embodiments, the inner wall of the noise reduction channel 123 may have a recess. In this way, when the refrigerator 10 is working, when its noise is transmitted to the noise reduction channel 123, the recess on the inner wall of the noise reduction channel 123 can further play a role in noise reduction, thereby improving the noise reduction effect of the noise reduction component 120.

[0059] like Figure 8 as well as Figure 9As shown, in some embodiments, the noise reduction channel 123 includes a first channel 124 and a second channel 125 communicating with the first channel 124. The first channel 124 and the second channel 125 are connected at an acute angle, a right angle, or an obtuse angle. Thus, by configuring the noise reduction channel 123 to be formed by connecting the first channel 124 and the second channel 125, and with the first channel 124 and the second channel 125 connected at an acute angle, a right angle, or an obtuse angle, when noise is transmitted to the noise reduction channel 123, the included angle between the first channel 124 and the second channel 125 can be used to further reduce the noise, thereby further improving the noise reduction effect of the noise reduction device 120.

[0060] like Figure 8 as well as Figure 9 As shown, in some embodiments, the first channel 124 and the second channel 125 are connected in an L-shape in the cross-section of the noise reduction element 120 in the width direction. Thus, the first channel 124 and the second channel 125 are connected at a right angle in the cross-section of the noise reduction element 120 in the width direction. Researchers have found in experiments that the noise reduction effect of the noise reduction channel 123 is better when the first channel 124 and the second channel 125 are connected at a right angle.

[0061] Of course, in some other embodiments, the connection between the first channel 124 and the second channel 125 in the width direction cross-section of the noise reduction component 120 can also be in the shape of ∠, ∧, ∨, ∩, ∪, ┌, ┐, etc.

[0062] In some embodiments, the connection point between the first channel 124 and the second channel 125 is arc-shaped. This facilitates the manufacturing of the noise reduction channel 123 and also improves the noise reduction effect of the noise reduction channel 123.

[0063] It should be noted that the cross-section of the noise reduction component 120 in the width direction is... Figure 8 The view shown.

[0064] like Figure 8 as well as Figure 9 As shown, in some embodiments, the depth of the first channel 124 is 3mm to 15mm. Thus, researchers have found from experiments that when the depth of the first channel 124 is 3mm to 15mm, it has a better noise reduction effect on the frequency of noise within the cabin 210.

[0065] Optionally, the depth of the first channel 124 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc.

[0066] In one example, the depth of the first channel 124 is 8mm.

[0067] like Figure 8 as well as Figure 9 As shown, in some embodiments, the depth of the second channel 125 is 20mm to 425mm. Thus, researchers have found from experiments that when the depth of the second channel 125 is 20mm to 425mm, it has a better noise reduction effect on the frequency of noise within the cabin 210.

[0068] Optionally, the depth of the second channel 125 can be 20mm, 222mm, 24mm, 25mm, 28mm, 30mm, 35mm, 38mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 68mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, 215mm, 220mm, 223mm, 250mm, 275mm, 300mm, 325mm, 350mm, 375mm, 400mm, 425mm, etc.

[0069] like Figure 7 As shown, in some embodiments, the height of the noise reduction channel 123 is 3mm to 20mm. Thus, researchers have found from experiments that when the depth of the first channel 124 is 3mm to 20mm as the height of the noise reduction channel 123, it has a better noise reduction effect on the frequency of noise within the cabin 210.

[0070] Optionally, the height of the noise reduction channel 123 can be 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.

[0071] In one example, the height of noise reduction channel 123 is 15mm.

[0072] It should be noted that the height of noise reduction channels 123 is Figure 7 As shown in diagram a, the depth of the first channel 124 is... Figure 8 as well as Figure 9 As shown in b. The depth of the second channel 125 is Figure 8 as well as Figure 9 c is shown.

[0073] In some embodiments, the partial noise reduction channel 123 of the noise reduction member 120 can be in a labyrinth shape, i.e., the partial noise reduction channel 123 can have an opening to the outside world and a winding path inside the noise reduction member 120, so as to form a labyrinth-shaped noise reduction channel 123. In this way, by arranging the noise reduction channel 123 in a labyrinth shape, it is beneficial to reduce noise in a larger frequency range, so as to improve the noise reduction effect.

[0074] It should be noted that the specific implementation of the material of the noise reduction member 120 can be various, including but not limited to rubber, silicone, etc.

[0075] As shown in Figure 11 and Figure 12 , in some embodiments, the machine compartment 210 further comprises a mounting seat 215 arranged on the outer bottom wall of the shell 211. Part of the noise reduction member 120 protrudes from the mounting seat 215. In this way, when the refrigerator 10 is installed, by arranging part of the noise reduction member 120 to protrude from the mounting seat 215, the flexible abutting body can abut against the ground to fit the ground and reduce the noise in the machine compartment 210 directly transmitted to the outside world.

[0076] As shown in Figure 5 and Figure 6 , in some embodiments, the noise reduction member 120 further comprises a second side wall 126 arranged opposite to the mounting wall 121, and the noise reduction channel 123 communicates with the second side wall 126. In this way, when the noise reduction member 120 is installed on the refrigerator 10, the noise generated inside the refrigerator 10 can enter the noise reduction channel 123 through the second side wall 126, further improving the sound absorption and sound insulation effect of the noise reduction member 120 on the noise, and further improving the noise reduction effect.

[0077] It should be noted that, as shown in Figure 10 , the noise reduction member 120 can have multiple noise reduction channels 123 arranged on a single side wall. For example, multiple noise reduction channels 123 are arranged on the first side wall 122. As shown in Figure 5 and Figure 6 , the noise reduction member 120 can have multiple noise reduction channels 123 arranged on both the first side wall 122 and the second side wall 126.

[0078] As shown in Figure 5 and Figure 6 , in some embodiments, the second side wall 126 is provided with a mounting groove 128, and the bottom wall of the mounting groove 128 is provided with a mounting hole 101, and the mounting hole 101 communicates with the mounting wall 121. In this way, when the noise reduction member 120 is installed on the refrigerator 10, the noise reduction member 120 can be installed on the machine compartment 210 of the refrigerator 10 through the mounting hole 101. During installation, a fastener can be used to pass through the mounting groove 128 and the mounting hole 101, so that the noise reduction member 120 is arranged on the machine compartment 210 of the refrigerator 10.

[0079] As shown in Figure 5 and Figure 6 shown, in some embodiments, the noise reduction member 120 is provided with a mounting member 129, and the noise reduction member 120 can be mounted to the refrigerator 10 through the mounting member 129. In this way, this mode is easy to implement and simple to realize.

[0080] As shown in Figure 5 and Figure 11 shown, in some embodiments, the mounting member 129 is provided with a mounting hole 101, and the mounting member 129 can be installed on the refrigerator 10 through the mounting hole 101. In this way, when the noise reduction member 120 is mounted to the refrigerator 10, the noise reduction member 120 can be mounted to the cabinet 210 of the refrigerator 10 through the mounting hole 101. During installation, a fastener can be passed through the mounting hole 101, and the mounting member can be used to fasten the noise reduction member 120 to the cabinet 210 of the refrigerator 10, so as to install the noise reduction member 120 on the cabinet 210 of the refrigerator 10.

[0081] Specifically, the noise reduction member 120 can be screwed and fixed to the cabinet 210 of the refrigerator 10 by a fastener.

[0082] Of course, the specific implementation mode of mounting the noise reduction member 120 to the cabinet 210 can also have many kinds, including riveting and fixing, adhesive fixing, and clamping fixing, etc.

[0083] As shown in Figures 4 to 6 shown, in some embodiments, the mounting wall 121 is provided with a relief groove 127. In this way, when the noise reduction member 120 is mounted to the outer bottom wall of the cabinet 210, the relief groove 127 of the mounting wall 121 can avoid the outer bottom wall of the cabinet 210, so as to avoid interference during installation of the noise reduction member 120, and improve the installation reliability of the noise reduction member 120.

[0084] As shown in Figure 11 and Figure 12 shown, in some embodiments, the cabinet 210 includes a housing 211 and a plurality of noise reduction members 120. The housing 211 is provided with a containing cavity 212. The bottom wall of the housing 211 is spaced apart to provide an air inlet 213 and an air outlet 214. The air inlet 213 and the air outlet 214 are respectively communicated with the containing cavity 212. The plurality of noise reduction members 120 includes a first noise reduction member 130 and a second noise reduction member 140, and the first noise reduction member 130 and the second noise reduction member 140 are respectively arranged on the outer bottom wall of the housing 211 along the depth direction of the containing cavity 212, and the first noise reduction member 130 and the second noise reduction member 140 are arranged opposite to each other along the length direction of the housing 211 and form a noise reduction space, and the air inlet 213 and the air outlet 214 are respectively communicated with the noise reduction space.

[0085] Thus, when the refrigerator 10 is working, the refrigerating device 300 such as the compressor 310 generates heat. The air inlet 213 and the air outlet 214 are arranged at the bottom wall of the shell 211 in a spaced manner, and the air inlet 213 and the air outlet 214 are respectively communicated with the accommodating cavity 212, so that the airflow outside enters and is discharged into the accommodating cavity 212 through the air inlet 213 and the air outlet 214 respectively, to dissipate the heat of the refrigerating device 300 such as the compressor 310 in the accommodating cavity 212. When it is working, it will generate noise, which can be transmitted to the outside of the machine compartment 210 through the air inlet 213 and the air outlet 214. The first noise reduction member 130 and the second noise reduction member 140 are arranged at the outer bottom wall of the shell 211 in a spaced manner, and the first noise reduction member 130 and the second noise reduction member 140 are arranged along the depth direction of the accommodating cavity 212, so that the first noise reduction member 130 and the second noise reduction member 140 are arranged in a relative manner along the length direction of the shell 211 to form a noise reduction space. The air inlet 213 and the air outlet 214 are respectively communicated with the noise reduction space, so that the noise generated by the machine compartment 210 when it is working enters the noise reduction space through the air inlet 213 and the air outlet 214, and the noise reduction member 120 reduces the noise generated by the machine compartment 210. This way can not only reduce the noise generated in the machine compartment 210, but also does not affect the heat dissipation in the machine compartment 210, and can improve the user experience.

[0086] It should be noted that the depth direction of the accommodating cavity 212 is the Z direction as shown in Figure 12 , and the length direction of the shell 211 is the X direction as shown in Figure 12 .

[0087] Specifically, when the refrigerator 10 is installed, the machine compartment 210 is located at the bottom of the cabinet assembly 200, and the noise reduction member 120 is arranged at the outer bottom wall of the shell 211 of the machine compartment 210, so that the noise reduction space forms an acoustic cavity with the ground, and the noise in the machine compartment 210 is transmitted to the acoustic cavity through the air inlet 213 and the air outlet 214, to be soundproofed and reduced by the first noise reduction member 130 and the second noise reduction member 140. This way can further improve the effect of noise reduction and further reduce the transmission of noise to the outside.

[0088] It should be noted that the specific implementation of the material of the noise reduction member 120 can be various, including but not limited to rubber, silicone and the like.

[0089] As shown in Figure 11 and Figure 13As shown, in some embodiments, the plurality of noise reduction components 120 further includes a third noise reduction component 150. The third noise reduction component 150 extends along the length of the housing 211 and is disposed on the outer bottom wall of the housing 211. The first noise reduction component 130, the third noise reduction component 150, and the second noise reduction component 140 are connected in sequence to form a noise reduction space. Thus, by extending the third noise reduction component 150 along the length of the housing 211 and disposing it on the outer bottom wall of the housing 211, the first noise reduction component 130, the third noise reduction component 150, and the second noise reduction component 140 are connected in sequence to form a noise reduction space. Using three noise reduction components 120 to form a noise reduction space can further improve the sound absorption and insulation effect of the compartment 210, improve the noise reduction effect, and further enhance the user's experience with the refrigerator 10. When the refrigerator 10 is installed, the noise reduction space, the bottom wall of the housing 211, and the ground form a sound cavity, resulting in a better noise reduction effect.

[0090] In some embodiments, the third noise reduction component 150 is disposed relative to the door assembly 110 near the back of the housing assembly 200. Thus, the noise reduction component 120 is not disposed on the front side of the housing assembly 200, and the air inlet 213 and air outlet 214 can communicate with the outside through the openings on the front side, thereby improving the heat dissipation efficiency of the compressor 310, cooling fan 320, etc. inside the housing 210.

[0091] like Figure 11 as well as Figure 14 As shown, in some embodiments, the plurality of noise reduction components 120 further includes a fourth noise reduction component 160. The fourth noise reduction component 160 extends along the length of the housing 211 and is disposed on the outer bottom wall of the housing 211. The first noise reduction component 130, the third noise reduction component 150, the second noise reduction component 140, and the fourth noise reduction component 160 are sequentially connected and surround the outer bottom wall of the housing 211. In this way, by using the first noise reduction component 130, the third noise reduction component 150, the second noise reduction component 140, and the fourth noise reduction component 160 sequentially connected and surrounding the outer bottom wall of the housing 211, the noise generated by the cabin 210 can be allowed to enter the noise reduction space, and the noise reduction components 120 surrounding the outer bottom wall of the housing 211 can be better utilized for sound absorption and insulation, thereby achieving a better noise reduction effect.
