Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a noise reduction device and a refrigerator. Background Technology

[0002] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance, and people's requirements for refrigerators are also gradually increasing. In addition to paying attention to the versatility of refrigerator functions and their aesthetic appearance, people are also increasingly demanding low noise levels during operation.

[0003] In related technologies, to reduce the noise generated by a refrigerator during operation, sound insulation and noise reduction devices are usually installed in the refrigerator to absorb the noise generated during operation and achieve low-noise operation. However, the sound absorption and sound insulation effects of current sound insulation and noise reduction devices are poor. Summary of the Invention

[0004] In view of this, the present disclosure provides a noise reduction component and a refrigerator. The noise reduction component has good sound absorption and sound insulation effects, which helps to reduce the noise generated by the refrigerator during operation, thereby improving the user's experience of using the refrigerator.

[0005] Specifically, this disclosure is achieved through the following technical solution.

[0006] According to a first aspect of the present disclosure, a noise reduction component is provided, comprising a mounting wall and a plurality of side walls, the noise reduction component being mountable via the mounting wall. At least one of the plurality of side walls is provided with a plurality of noise reduction channels, the plurality of noise reduction channels being spaced apart. One end of each noise reduction channel is connected to the outside, and the other end is closed.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] During assembly, this noise-reducing component can be installed on the refrigerator via a mounting wall. Multiple noise-reducing channels are formed on at least one of the multiple side walls. When noise is transmitted to the noise-reducing component, on the one hand, the component isolates the noise from the outside environment, preventing it from being transmitted. On the other hand, noise can enter the noise-reducing channels. By sealing one end of each channel, the sound wave energy is absorbed or reflected by the channel wall as the noise propagates within the sealed channel, thus reducing the noise intensity. This noise-reducing component has a good noise reduction effect, which improves the user experience.

[0009] The technical solution disclosed herein will be further explained below.

[0010] In one embodiment, the plurality of sidewalls includes a first sidewall disposed adjacent to the mounting wall. The first sidewall is provided with a plurality of noise reduction channels.

[0011] In one embodiment, the multiple sidewalls include a second sidewall disposed opposite to the mounting wall. The second sidewall is provided with multiple noise reduction channels.

[0012] In one embodiment, the second sidewall is provided with a mounting groove, and the bottom wall of the mounting groove is provided with a mounting hole, which communicates with the mounting wall. And / or, the noise reduction component is provided with a mounting member, and the mounting member is provided with a mounting hole.

[0013] In one embodiment, the depths between at least two noise reduction channels are not equal.

[0014] In one embodiment, the noise reduction channel includes a first channel and a second channel connected to the first channel. The first channel and the second channel are connected at an acute angle, a right angle, or an obtuse angle.

[0015] In one embodiment, the first channel and the second channel are connected in an L-shape in the cross-section of the noise reduction component in the width direction; or, the connection between the first channel and the second channel has an arc.

[0016] In one embodiment, the depth of the first channel is 3mm to 15mm. And / or, the depth of the second channel is 20mm to 425mm. And / or, the height of the noise reduction channel is 3mm to 20mm.

[0017] In one embodiment, the mounting wall is provided with a clearance groove.

[0018] According to a second aspect of the present disclosure, a refrigerator is provided, the refrigerator including a cabinet assembly and a noise reduction component as described in any of the above embodiments. The cabinet assembly includes a compartment disposed at the bottom of the cabinet assembly, and the noise reduction component is disposed in the compartment.

[0019] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0020] When the refrigerator is operating, the refrigeration unit inside the refrigerator compartment activates to provide cooling. A noise reduction component is installed in the compartment via a mounting wall. When the refrigeration unit operates, the noise generated by it is transmitted to the noise reduction component. Upon reaching the noise reduction component, it serves two purposes: firstly, it isolates the noise from the outside environment, preventing it from being transmitted. Secondly, the noise can enter a noise reduction channel. By sealing one end of the channel, the sound wave energy is absorbed or reflected by the channel wall as it propagates within the sealed channel, thus reducing the noise intensity. This refrigerator utilizes the noise reduction component described in any of the above embodiments, and this component is effective, improving the user experience.

[0040] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0041] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, 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 relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0042] With the development of society and the economy and the improvement of people's living standards, refrigerators have gradually become an indispensable household appliance, and people's requirements for refrigerators are also gradually increasing. In addition to paying attention to the versatility of refrigerator functions and their aesthetic appearance, people are also increasingly demanding low noise levels during operation.

[0043] In related technologies, to reduce the noise generated by a refrigerator during operation, sound insulation and noise reduction components are typically installed to absorb the noise produced, achieving low-noise operation. However, current sound insulation and noise reduction components have poor sound absorption and insulation effects.

[0044] Based on this, such as Figures 1 to 5 As shown, a noise reduction component 120 and a refrigerator 10 are provided. The noise reduction component 120 has good sound absorption and sound insulation effects, which helps to reduce the noise generated by the refrigerator 10 during operation, thereby improving the user's experience of using the refrigerator 10.

[0045] like Figure 5 as well as Figure 6 As shown, a noise reduction component 120 is provided, which includes a mounting wall 121 and multiple side walls. The noise reduction component 120 can be installed through the mounting wall 121. At least one of the multiple side walls is provided with multiple noise reduction channels 123, which are spaced apart from each other. One end of each noise reduction channel 123 is connected to the outside, and the other end is closed.

[0046] Thus, during assembly, the noise reduction component 120 can be installed in the refrigerator 10 via the mounting wall 121. Multiple noise reduction channels 123 are formed on at least one of the multiple side walls. When noise is transmitted to the noise reduction component 120, on the one hand, the noise reduction component 120 isolates the noise from the outside world, preventing noise from being transmitted to the outside. On the other hand, noise can enter the noise reduction channel 123. Because one end of the noise reduction channel 123 is closed, when the noise enters the noise reduction channel 123 and propagates within the closed channel, the sound wave energy is absorbed or reflected by the wall of the noise reduction channel 123, thereby reducing the noise intensity. This noise reduction component 120 has a good noise reduction effect, which is beneficial to improving the user experience.

[0047] It should be noted that there are several ways to implement the noise reduction component 120, including integral molding and separate manufacturing and reassembly.

[0048] It should be noted that there are various ways to implement the molding process of the noise reduction component 120, including but not limited to co-extrusion, compression molding and injection molding.

[0049] like Figures 1 to 3As shown, a refrigerator 10 is also provided. The refrigerator 10 includes a door assembly 110, a cabinet assembly 200, and a noise reduction component 120 as described in the above embodiments. The cabinet assembly 200 includes a compartment 210, which is located at the bottom of the cabinet assembly 200, and the noise reduction component 120 is disposed in the compartment 210.

[0050] In some embodiments, the noise reduction component 120 is bonded and fixed to the housing 210. This method is easy to implement and simple to execute.

[0051] like Figure 1 as well as Figure 2 As shown, in some embodiments, the refrigerator 10 further includes a refrigeration unit 300 disposed within the compartment 210.

[0052] Thus, when the refrigerator 10 is working, the refrigeration unit 300 inside the refrigerator 10's compartment 210 is activated to provide cooling for the refrigerator 10. The noise reduction component 120 is installed in the compartment 210 via the mounting wall 121. When the refrigeration unit 300 inside the compartment 210 is working, the noise generated by the refrigeration unit 300 can be transmitted to the noise reduction component 120. When the noise is transmitted to the noise reduction component 120, on the one hand, the noise reduction component 120 isolates the noise from the outside world, preventing the noise from being transmitted to the outside. On the other hand, the noise can enter the noise reduction channel 123. Because one end of the noise reduction channel 123 is closed, when the noise enters the noise reduction channel 123 and propagates within the closed channel, the sound wave energy is absorbed or reflected by the wall of the noise reduction channel 123, thereby reducing the noise intensity. The refrigerator 10 uses the noise reduction component 120 in any of the above embodiments, and the noise reduction component 120 is effective, which helps to improve the user experience of the refrigerator 10.

[0053] In some embodiments, the refrigeration device 300 includes a compressor 310 and a cooling fan 320, which are disposed within the housing 210. Thus, when the compressor 310 is operating, the cooling fan 320 helps dissipate the heat generated by the compressor 310 during operation, preventing the compressor 310 from overheating and ensuring the normal operation of the compressor 310.

[0054] like Figure 1 as well as Figure 2 As shown, in some embodiments, the door assembly 110 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 inside the compressor compartment 210 starts to cool the storage cavity 220, providing a refrigerated / frozen 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 Figure 5 as well as Figure 6 As shown, in some embodiments, the multiple sidewalls include a first sidewall 122 disposed adjacent to the mounting wall 121. The first sidewall 122 is provided with a plurality of noise reduction channels 123. Thus, by providing a plurality of noise reduction channels 123 on the first sidewall 122 disposed adjacent to the mounting wall 121, the noise reduction effect of the noise reduction component 120 is improved, thereby enhancing the user experience.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] It should be noted that the cross-section of the noise reduction component 120 in the width direction is... Figure 8 The view shown.

[0065] 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.

[0066] 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.

[0067] In one example, the depth of the first channel 124 is 8mm.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] In one example, the height of noise reduction channel 123 is 15mm.

[0073] 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.

[0074] In some embodiments, a portion of the noise reduction channel 123 of the noise reduction component 120 may be labyrinth-shaped. That is, a portion of the noise reduction channel 123 may have an opening to the outside, and the channel within the noise reduction component 120 may have a tortuous path, thus forming a labyrinth-shaped noise reduction channel 123. In this way, by setting the noise reduction channel 123 to a labyrinth shape, it is beneficial to reduce noise over a wider range of noise frequencies, thereby improving the noise reduction effect.

[0075] It should be noted that the noise reduction component 120 can be made of various materials, including but not limited to rubber, silicone, etc.

[0076] like Figure 11 as well as Figure 12 As shown, in some embodiments, the housing 210 further includes a mounting base 215 disposed on the outer bottom wall of the housing 211. A portion of the noise-reducing component 120 protrudes from the mounting base 215. Thus, during refrigerator 10 installation, by having a portion of the noise-reducing component 120 protrude from the mounting base 215, the noise-reducing component 120 can abut against the ground, thus reducing the direct transmission of noise from inside the housing 210 to the outside.

[0077] like Figure 5 as well as Figure 6 As shown, in some embodiments, the multiple sidewalls further include a second sidewall 126 disposed opposite to the mounting wall 121, and the second sidewall 126 is provided with a plurality of noise reduction channels 123. Thus, by providing a plurality of noise reduction channels 123 on the second sidewall 126 disposed opposite to the mounting wall 121, the noise reduction effect of the noise reduction component 120 is improved, thereby enhancing the user experience.

[0078] It should be noted that the specific implementation of having multiple noise reduction channels 123 on at least one of the multiple sidewalls can be as follows: Figure 5 as well as Figure 6 As shown, the noise reduction component 120 can simultaneously open multiple noise reduction channels 123 on the first sidewall 122 and the second sidewall 126. Alternatively, it can be as follows: Figure 10 As shown, multiple noise reduction channels 123 are opened on a certain side wall. For example, multiple noise reduction channels 123 are opened on the first side wall 122 or the second side wall 126.

[0079] like Figure 5 as well as Figure 6As shown, in some embodiments, the second sidewall 126 is provided with a mounting groove 128, and the bottom wall of the mounting groove 128 is provided with a mounting hole 101, which communicates with the mounting wall 121. Thus, when the noise reduction component 120 is installed in the refrigerator 10, it can be installed into the refrigerator 10's compartment 210 through the mounting hole 101. During installation, fasteners can be used through the mounting groove 128 and through the mounting hole 101 to allow the noise reduction component 120 to be installed in the refrigerator 10's compartment 210.

[0080] like Figure 5 as well as Figure 6 As shown, in some embodiments, the noise reduction component 120 is provided with a mounting member 129, through which the noise reduction component 120 can be mounted to the refrigerator 10. This method is easy to implement and simple to execute.

[0081] like Figure 5 as well as Figure 11 As shown, in some embodiments, the mounting member 129 is provided with a mounting hole 101, through which the mounting member 129 can be installed in the refrigerator 10. Thus, when the noise reduction component 120 is installed in the refrigerator 10, the noise reduction component 120 can be installed in the refrigerator 10's compartment 210 through the mounting hole 101. During installation, fasteners can be inserted through the mounting hole 101, and the mounting member can be used to securely connect the noise reduction component 120 to the refrigerator 10's compartment 210, thereby installing the noise reduction component 120 in the refrigerator 10's compartment 210.

[0082] Specifically, the noise reduction component 120 can be screwed into the refrigerator compartment 210 using fasteners.

[0083] Of course, there are many other ways to install the noise reduction component 120 into the engine compartment 210, including riveting, adhesive bonding, and snap-fitting, etc.

[0084] like Figures 4 to 6 As shown, in some embodiments, the mounting wall 121 is provided with a clearance groove 127. Thus, when the noise reduction component 120 is installed on the outer bottom wall of the cabin 210, the clearance groove 127 of the mounting wall 121 can avoid the outer bottom wall of the cabin 210, so as to avoid interference during the installation of the noise reduction component 120 and improve the installation reliability of the noise reduction component 120.

[0085] like Figure 11 as well as Figure 12As shown, in some embodiments, the cabin 210 includes a housing 211 and a plurality of noise reduction components 120. The housing 211 has a receiving cavity 212. The bottom wall of the housing 211 is provided with an air inlet 213 and an air outlet 214 spaced apart. The air inlet 213 and the air outlet 214 are respectively connected to the receiving cavity 212. The plurality of noise reduction components 120 include a first noise reduction component 130 and a second noise reduction component 140. The first noise reduction component 130 and the second noise reduction component 140 extend along the depth direction of the receiving cavity 212 and are respectively disposed on the outer bottom wall of the housing 211. The first noise reduction component 130 and the second noise reduction component 140 are arranged opposite to each other along the length direction of the housing 211 and form a noise reduction space. The air inlet 213 and the air outlet 214 are respectively connected to the noise reduction space.

[0086] Thus, when the refrigerator 10 is operating, the compressor 310 and other refrigeration devices 300 generate heat. By providing air inlets 213 and outlets 214 at intervals on the bottom wall of the housing 211, and by connecting the air inlets 213 and outlets 214 to the receiving cavity 212, external airflow enters and exits the receiving cavity 212 through the air inlets 213 and outlets 214, respectively, to dissipate heat from the compressor 310 and other refrigeration devices 300 within the receiving cavity 212. During operation, it generates noise, which can be transmitted to the outside of the housing 210 through the air inlets 213 and outlets 214. By providing a first noise reduction component 130 and a second noise reduction component 140 on the outer bottom wall of the housing 211, and by extending the first noise reduction component 130 and the second noise reduction component 140 along the depth direction of the receiving cavity 212, the first noise reduction component 130 and the second noise reduction component 140 are arranged opposite each other along the length direction of the housing 211, forming a noise reduction space. By connecting the air inlet 213 and air outlet 214 to the noise reduction space, the noise generated by the chassis 210 during operation enters the noise reduction space through the air inlet 213 and air outlet 214. The noise reduction component 120 then reduces the noise generated by the chassis 210. This method can reduce the noise generated inside the chassis 210 without affecting the heat dissipation inside the chassis 210, thereby improving the user experience.

[0087] It should be noted that the depth direction of the receiving cavity 212 is as follows: Figure 12 As shown in the Z direction, the length direction of the housing 211 is as follows: Figure 12 The X direction is shown.

[0088] Specifically, when the refrigerator 10 is installed, the compartment 210 is located at the bottom of the cabinet assembly 200, and the noise reduction component 120 is installed on the outer bottom wall of the shell 211 of the compartment 210, so that the noise reduction space and the ground form a sound cavity. The noise inside the compartment 210 is transmitted to the sound cavity through the air inlet 213 and the air outlet 214, so that the first noise reduction component 130 and the second noise reduction component 140 can perform sound insulation and noise reduction. This method can further improve the noise reduction effect and further reduce the noise transmitted to the outside.

[0089] like Figure 11 as well as Figure 13 As 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.
