Description

Technical Field

[0001] This application relates to the technical field of air conditioner noise reduction, and more particularly to an outdoor unit for an air conditioner. Background Technology

[0002] The outdoor unit of an air conditioner is a key component of the air conditioning system. It works in concert with components such as the condenser, compressor, and fan to dissipate heat and cool the air. However, the noise generated during the operation of the outdoor unit, especially the noise from the compressor, can disturb the surrounding environment and affect the quality of life for users, thus becoming a problem that needs to be addressed.

[0003] To reduce compressor noise, existing technologies commonly use sound-absorbing cotton as the sound insulation material. This sound-absorbing cotton includes outer layer sound-absorbing cotton and top layer sound-absorbing cotton. Multiple Velcro straps are installed, with one end connecting to the top sound-absorbing cotton and the other end connecting to the outer layer sound-absorbing cotton.

[0004] However, in existing technologies, gaps easily appear between the outer and top sound insulation cotton connected by Velcro during actual assembly, resulting in poor sound insulation performance. Moreover, the stability of this adhesive structure is poor, and its sound insulation performance may further decrease due to loosening after long-term use. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an outdoor air conditioning unit that, through a first flange with the top sound insulation cotton edge pointing downwards, can be bent downwards and overlap the outer peripheral wall of the outer sound insulation cotton to completely cover and seal the gap between the outer and top sound insulation cotton. Furthermore, a second fitting portion is provided on the first flange and connects to the first fitting portion on the outer sound insulation cotton, achieving a connection between the top and outer sound insulation cotton. Simultaneously, the connection between the first and second fitting portions further seals the gap between the first flange and the outer sound insulation cotton, reducing the possibility of noise leakage.

[0007] To achieve the above objectives, this utility model provides an outdoor unit for an air conditioner, comprising: case; A compressor, wherein the compressor is disposed within the housing; An outdoor heat exchanger, which is used to exchange heat between the refrigerant inside it and the outside air; An outdoor fan, used to blow airflow toward the outdoor heat exchanger; A sound insulation component, wherein the sound insulation component is disposed within the housing, the sound insulation component comprising: The outer sound insulation cotton has an opening at its top; the compressor is fitted inside the outer sound insulation cotton. Top sound insulation cotton, which is disposed on top of the outer sound insulation cotton and is used to close the top opening of the outer sound insulation cotton; the edge of the top sound insulation cotton is bent with a first flange; The first bonding portion is bonded to the outer peripheral wall of the top of the outer sound insulation cotton; the extension direction of the first bonding portion is arranged along the peripheral wall of the outer sound insulation cotton. The second bonding part is disposed on the first flange, and the extension direction of the second bonding part is disposed along the extension direction of the first flange; The second bonding portion is used to connect with the first bonding portion.

[0008] In this technical solution, the first flange, with its downward-facing edge, bends downwards and overlaps the outer perimeter of the outer sound insulation cotton, completely covering and sealing the gap between the outer and top sound insulation cotton. A second bonding portion is located on the first flange and connects to the first bonding portion on the outer sound insulation cotton, thus connecting the top and outer sound insulation cotton. Simultaneously, the connection between the first and second bonding portions further seals the gap between the first flange and the outer sound insulation cotton, reducing the possibility of noise leakage. This design significantly reduces noise emissions from the outdoor unit of the air conditioner, improving the comfort of the surrounding environment. Its noise reduction advantage is particularly pronounced at night or in quiet areas, helping air conditioning products meet higher environmental standards and enhancing market competitiveness.

[0009] In some embodiments of this application, the width of the second fitting portion does not exceed the width of the first flange.

[0010] In this technical solution, the second bonding portion is positioned entirely on one side of the first bonding edge, preventing it from protruding and improving aesthetics. Connecting the first and second bonding portions involves simply pressing the first bonding edge onto the outer sound insulation cotton, thus improving production efficiency. Furthermore, this design ensures the second bonding portion is supported by the first bonding edge. If the second bonding portion is too wide, it may exceed the effective support range of the first bonding edge, leading to weak adhesion or uneven stress on the first bonding edge. Therefore, this design ensures the first bonding edge receives uniform force, stably supporting the second bonding portion and allowing for a stable connection between the second and first bonding portions, thereby improving sound insulation.

[0011] In some embodiments of this application, the width of the second mating portion is 20 mm.

[0012] In the technical solution, during practical application, the 20mm wide second bonding portion ensures sufficient contact area between the second and first bonding portions, achieving a tight fit. It also avoids increased assembly difficulty or material waste due to an excessively wide bonding portion. Furthermore, the 20mm width of the second bonding portion facilitates standardized production or procurement, which is beneficial for large-scale manufacturing or purchasing, reducing production costs.

[0013] In some embodiments of this application, a pipe hole is provided through the top sound insulation cotton, and a first slit is provided on the top sound insulation cotton, with one end of the first slit communicating with the pipe hole; a second slit is provided on the first flange, with one end of the second slit communicating with the first slit and the other end communicating with the outside.

[0014] In this technical solution, the placement of the conduit hole allows pipes and cables to pass through the top sound insulation cotton in an orderly manner, ensuring that the cables and pipes can connect to the external structure. One end of the first slit connects to the conduit hole, and the second slit connects to the first slit, allowing direct connection between the conduit hole and the outside world. This provides a path for cables and pipes to enter the conduit hole; they can pass through the second slit and then the first slit. Furthermore, the first flange and the top sound insulation cotton can be on the same plane before bending downwards. Without the second slit, the closed ring-shaped first flange cannot be bent. Because of the second slit, the first flange can be bent relative to the top sound insulation cotton, thus completing the bending design of the first flange, facilitating production and installation.

[0015] In some embodiments of this application, the second bonding portion is disconnected, and the disconnection point of the second bonding portion is located at the second seam and corresponds to the second seam.

[0016] In the existing technical solution, if the second fitting part is a complete closed loop, it can only be installed after the first flange has been bent and formed. Furthermore, the closed loop of the second fitting part is not easily bent or deformed; during installation, it is difficult to bend and fit the second fitting part towards the first fitting part. Therefore, in this application, the second fitting part is designed as a disconnect, with the disconnection point located at and corresponding to the second seam. This ensures that the second fitting part bends, folds, and deforms synchronously with the first flange without affecting pipeline passage, thus facilitating production and installation.

[0017] In some embodiments of this application, at least one third slit is provided on the first flange, and one end of the third slit extends to the connection between the top sound insulation cotton and the first flange.

[0018] In the technical solution, without the third gap, the closed annular first flange cannot be bent. This application ensures that the first flange can be bent and folded by setting the third gap. In the actual assembly process, the first flange needs to fit tightly against the periphery of the outer sound insulation cotton, and the third gap allows the flange to bend and adjust its shape more flexibly to better fit the contour of the compressor and reduce noise leakage caused by shape mismatch. At the same time, the presence of the third gap helps to disperse the stress generated by the flange when it is under force.

[0019] In some embodiments of this application, the third seam divides the first flange into a bonding segment, and the number of the second bonding portions is the same as the number of the bonding segments and they are arranged in a one-to-one correspondence.

[0020] In this technical solution, each segment of the first flange after it is divided is provided with a corresponding second bonding part. This ensures that each segment can adhere to the outer sound insulation cotton, avoiding localized noise leakage caused by uneven bonding. Simultaneously, this design enhances the stability of the bonding connection. Furthermore, this design improves the flexibility and adaptability of the sound insulation component. The independence of different bonding segments allows the flange to better adapt to the complex shape of the compressor's perimeter. During manufacturing, it also facilitates individual adjustment and optimization of each bonding segment and its corresponding bonding part, effectively reducing noise emissions from the outdoor unit of the air conditioner.

[0021] In some embodiments of this application, the thickness of the top sound insulation cotton is at least 3 mm; and / or, the thickness of the outer sound insulation cotton is at least 3 mm.

[0022] In this technical solution, the increased thickness of the top and outer sound insulation cotton effectively increases the sound damping of the sound insulation material, resulting in greater attenuation of noise during propagation. The 3mm thickness of both the top and outer sound insulation cotton ensures sound insulation performance without adding unnecessary cost and weight due to excessive thickness. In practical use, when the compressor generates noise, the thickness of the sound insulation cotton effectively absorbs and isolates mid-to-high frequency noise, reducing noise propagation, and is particularly effective at reducing common operating noise frequencies of air conditioner outdoor units.

[0023] In some embodiments of this application, the sum of the thicknesses of the first bonding portion and the second bonding portion is 1.8 to 2.2 mm.

[0024] In this technical solution, this thickness range ensures a tight fit between the first flange and the outer sound insulation cotton, thereby reducing noise leakage from the connection between the first and second bonding portions. Furthermore, the first and second bonding portions within this thickness range also balance strength and durability.

[0025] In addition, this application also provides an outdoor unit for an air conditioner, which includes: case; A compressor, wherein the compressor is disposed within the housing; An outdoor heat exchanger, which is used to exchange heat between the refrigerant inside it and the outside air; An outdoor fan, used to blow airflow toward the outdoor heat exchanger; A sound insulation component, wherein the sound insulation component is disposed within the housing, the sound insulation component comprising: An outdoor unit for an air conditioner, characterized in that it comprises: case; A compressor, wherein the compressor is disposed within the housing; An outdoor heat exchanger, which is used to exchange heat between the refrigerant inside it and the outside air; An outdoor fan, used to blow airflow toward the outdoor heat exchanger; A sound insulation component, wherein the sound insulation component is disposed within the housing, the sound insulation component comprising: The outer sound insulation cotton has an opening at the top; the compressor is fitted inside the outer sound insulation cotton; the edges of the outer sound insulation cotton are bent with a second flange; Top sound insulation cotton, which is disposed on top of the outer sound insulation cotton and is used to close the top opening of the outer sound insulation cotton; The third bonding portion is bonded to the second flange; the extension direction of the third bonding portion is set along the extension direction of the second flange. The fourth bonding part is disposed on the top sound insulation cotton, and the extension direction of the fourth bonding part is disposed along the edge of the top sound insulation cotton; The third bonding portion is used to connect with the fourth bonding portion.

[0026] In this technical solution, the second flange of the outer sound insulation cotton can be bent and overlapped with the top sound insulation cotton to completely cover and seal the gap between the outer and top sound insulation cotton. Furthermore, a third bonding portion is located on the second flange and connects with a fourth bonding portion on the top sound insulation cotton, thus connecting the top and outer sound insulation cotton. This connection further seals the gap between the second flange and the top sound insulation cotton, reducing the possibility of noise leakage. This design can significantly reduce noise emissions from the outdoor unit of the air conditioner, improving the comfort of the surrounding environment. Its noise reduction advantage is particularly pronounced at night or in quiet areas, helping air conditioning products meet higher environmental standards and enhancing market competitiveness.

[0031] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. In this application, the outdoor unit of the air conditioner includes a casing, within which a compressor, an outdoor heat exchanger, and an outdoor fan are housed. The compressor compresses a low-temperature, low-pressure refrigerant to a high-temperature, high-pressure refrigerant and outputs it. The refrigerant entering the outdoor heat exchanger exchanges heat with the outside air, thereby changing its temperature. The outdoor fan directs airflow towards the outdoor heat exchanger, improving its heat exchange efficiency. Furthermore, a sound insulation component is installed within the casing to reduce compressor noise, thus achieving noise reduction and improving the user experience.

[0032] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings. Please refer to all the attached drawings. In one illustrative embodiment of the outdoor unit of the air conditioner of this utility model, the outdoor unit includes a housing. The housing is the mounting base for the outdoor fan. Its main function is to provide installation and protection for internal components such as the compressor, outdoor heat exchanger and outdoor fan, and to prevent external physical damage or environmental interference.

[0033] In some embodiments, the outdoor unit of the air conditioner further includes a compressor disposed within a housing. The compressor is used to compress a low-temperature, low-pressure refrigerant to a high-temperature, high-pressure refrigerant and then output it.

[0034] In some embodiments, the outdoor unit of the air conditioner also includes an outdoor heat exchanger for exchanging heat between the refrigerant inside it and the outside air.

[0035] In some embodiments, the outdoor unit of the air conditioner also includes an outdoor fan, which is used to blow airflow toward the outdoor heat exchanger, thereby improving the heat exchange effect of the outdoor heat exchanger.

[0036] In some embodiments, the outdoor unit of the air conditioner also includes a sound insulation component disposed within the housing. The sound insulation component is used to reduce the noise of the compressor, thereby achieving noise reduction and improving the user experience.

[0037] In some embodiments, the sound insulation component includes an outer sound insulation cotton 100, the top of which is open; the outer sound insulation cotton 100 is fitted with a compressor.

[0038] In some embodiments, the sound insulation component includes a top sound insulation cotton 200 disposed on top of the outer sound insulation cotton 100, which is used to close the top opening of the outer sound insulation cotton 100; the edge of the top sound insulation cotton 200 is bent with a first flange 201.

[0039] In some embodiments, the sound insulation component includes a first bonding portion 300 and a second bonding portion 400. The first bonding portion 300 is bonded to the outer peripheral wall of the top of the peripheral sound insulation cotton 100; the extending direction of the first bonding portion 300 is arranged along the peripheral wall of the peripheral sound insulation cotton 100. The second bonding portion 400 is disposed on the first flange 201, and the extending direction of the second bonding portion 400 is arranged along the extending direction of the first flange 201; the second bonding portion 400 is used to connect with the first bonding portion 300.

[0040] Through the above solution, the first flange 201, which folds downwards along the edge of the top sound insulation cotton 200, can be bent downwards and overlap the outer periphery of the outer sound insulation cotton 100, completely covering and sealing the gap between the outer sound insulation cotton 100 and the top sound insulation cotton 200. Furthermore, the second fitting part 400 is disposed on the first flange 201 and connects with the first fitting part 300 on the outer sound insulation cotton 100, thus achieving the connection between the top sound insulation cotton 200 and the outer sound insulation cotton 100. Simultaneously, the connection between the first fitting part 300 and the second fitting part 400 further seals the gap between the first flange 201 and the outer sound insulation cotton 100, reducing the possibility of noise leakage. This design can significantly reduce the noise emission of the air conditioner outdoor unit, improve the comfort of the surrounding environment, especially at night or in quiet areas, where its noise reduction advantage is more pronounced. This helps air conditioning products meet higher environmental standards and enhances market competitiveness.

[0041] In some embodiments, the first bonding portion 300 and the second bonding portion 400 are constructed using Velcro, also known as hook and loop fasteners. Specifically, the male and female fasteners are the first bonding portion 300 and the second bonding portion 400, respectively. This structure facilitates disassembly and installation, and allows for easy adjustment of their relative positions. Furthermore, it utilizes commonly used standard parts, making it easy to procure and reducing costs.

[0042] In one embodiment, at least one of the first bonding portion 300 and the second bonding portion 400 is adhesive, which enables them to adhere to each other. This results in a more secure bond and reduces sound leakage.

[0043] In some embodiments, the width of the second bonding portion 400 does not exceed the width of the first flange 201. This design ensures that the second bonding portion 400 is completely located on one side, preventing it from protruding from the first flange 201 and improving aesthetics. When connecting the first bonding portion 300 and the second bonding portion 400, the first flange 201 is simply pressed against the first bonding portion 300 on the outer sound insulation cotton 100, improving production efficiency. On the other hand, this design ensures that the second bonding portion 400 can be supported by the first flange 201. If the second bonding portion 400 is too wide, it may exceed the effective support range of the first flange 201, resulting in poor adhesion or uneven stress on the first flange 201. Therefore, this design ensures that the first flange 201 is evenly stressed, stably supporting the second bonding portion 400, allowing the second bonding portion 400 to stably connect to the first bonding portion 300, thereby improving sound insulation.

[0044] In some embodiments, the first bonding portion 300 and the second bonding portion 400 have the same width. This ensures a tight and uniform fit, enhances sound insulation, and reduces noise leakage.

[0045] In one embodiment, the widths of the first bonding portion 300 and the second bonding portion 400 may be different. When connecting the first bonding portion 300 and the second bonding portion 400, their positions can be adjusted for adaptive adjustment.

[0046] In some embodiments, the width of the second bonding portion 400 is 20 mm. In practical applications, a 20 mm wide second bonding portion 400 ensures sufficient contact area between the second bonding portion 400 and the first bonding portion 300, achieving a tight fit. It also avoids increased assembly difficulty or material waste due to an excessively wide bonding portion. Furthermore, the 20 mm wide second bonding portion 400 facilitates standardized production or procurement, which is beneficial for large-scale manufacturing or procurement, reducing production costs.

[0047] In some embodiments, a conduit hole 202 is provided through the top sound insulation cotton 200, and a first slit 203 is provided on the top sound insulation cotton 200, one end of which communicates with the conduit hole 202; a second slit 204 is provided on the first flange 201, one end of which communicates with the first slit 203, and the other end communicates with the outside. The conduit hole 202 allows pipes and cables to pass through the top sound insulation cotton 200 in an orderly manner, ensuring that the cables and pipes can be connected to the external structure. One end of the first slit 203 communicates with the conduit hole 202, and the second slit 204 communicates with the first slit 203, so that the conduit hole 202 can be directly connected to the outside. A path is provided for cables and pipes to enter the conduit hole 202, and the cables and pipes can first pass through the second slit 204 and then through the first slit 203 to enter the conduit hole 202. Furthermore, the first flange 201 and the top sound insulation cotton 200 can be on the same plane and then bent downwards to form the flange. Without the second gap 204, the closed ring-shaped first flange 201 cannot be bent. However, because of the second gap 204, the first flange 201 can be bent relative to the top sound insulation cotton 200, thus completing the bending setting of the first flange 201, which facilitates production and installation.

[0048] In some embodiments, the second fitting portion 400 is disconnected, with the disconnection point located at and corresponding to the second seam 204. If the second fitting portion 400 is a complete closed loop, it can only be installed after the first flange 201 has been bent. Furthermore, the closed loop second fitting portion 400 is not easily bent or deformed; during installation, it is not easy to bend and fit the second fitting portion 400 towards the first fitting portion 300. Therefore, in this application, the second fitting portion 400 is disconnected, with the disconnection point located at and corresponding to the second seam 204. This ensures that the second fitting portion 400 and the first flange 201 are bent, folded, and deformed synchronously without affecting the passage of the pipeline, thereby facilitating production and installation.

[0049] In some embodiments, at least one third slit is provided on the first flange 201, with one end of the third slit extending to the connection between the top sound insulation cotton 200 and the first flange 201. Without the third slit, the closed annular first flange 201 cannot be bent. This application ensures that the first flange 201 can be bent and folded by providing the third slit. In actual assembly, the first flange 201 needs to fit tightly against the peripheral wall of the outer sound insulation cotton 100, and the third slit allows the flange to bend and adjust its shape more flexibly to better fit the contour of the compressor and reduce noise leakage caused by shape mismatch. At the same time, the presence of the third slit helps to disperse the stress generated by the flange when it is under force.

[0050] In some embodiments, the third seam divides the first flange 201 into bonding segments, and the number of second bonding portions 400 is the same as the number of bonding segments and they are arranged in a one-to-one correspondence. This ensures that each bonding segment after the first flange 201 is divided has a corresponding second bonding portion 400, thereby ensuring that each bonding segment can adhere to the outer sound insulation cotton 100, avoiding localized noise leakage caused by uneven bonding. Simultaneously, this design enhances the stability of the bonding connection. Furthermore, this design improves the flexibility and adaptability of the sound insulation component. The independence of different bonding segments allows the flange to better adapt to the complex shape of the compressor's periphery, and during manufacturing, it facilitates individual adjustment and optimization of each bonding segment and its corresponding bonding portion, thereby effectively reducing noise emissions from the outdoor unit of the air conditioner.

[0051] In some embodiments, when there are multiple third seams, the spacing between any two adjacent third seams is equal. That is, the length of each bonding segment is equal. The consistent length of each bonding segment is primarily to ensure that the first flange 201 can uniformly and tightly adhere to the outer periphery of the outer sound insulation cotton 100, effectively reducing noise leakage caused by uneven bonding and improving the overall sound insulation effect. Simultaneously, this uniform layout also enhances the flexibility and stability of the structure, allowing it to better adapt to the shape of the compressor and further improve noise reduction performance.

[0052] In some embodiments, the thickness of the top sound insulation cotton 200 is at least 3 mm. The thickness of the top sound insulation cotton 200 effectively increases the sound damping of the sound insulation material, resulting in greater attenuation of noise during propagation. A 3 mm thickness of the top sound insulation cotton 200 ensures sound insulation performance without adding unnecessary cost and weight due to excessive thickness. In practical use, when the compressor generates noise, the thickness of the top sound insulation cotton 200 effectively absorbs and isolates mid-to-high frequency noise, reducing noise propagation, and is particularly effective at reducing common operating noise frequencies of air conditioner outdoor units.

[0053] In some embodiments, the thickness of the outer sound insulation cotton 100 is at least 3 mm. The thickness of the outer sound insulation cotton 100 effectively increases the sound damping of the sound insulation material, resulting in greater attenuation of noise during propagation. A 3 mm thickness of the outer sound insulation cotton 100 ensures sound insulation performance without adding unnecessary cost and weight due to excessive thickness. In practical use, when the compressor generates noise, the thickness of the outer sound insulation cotton 100 effectively absorbs and isolates mid-to-high frequency noise, reducing noise propagation, and is particularly effective at reducing common operating noise frequencies of air conditioner outdoor units.

[0054] In some embodiments, the combined thickness of the first bonding portion 300 and the second bonding portion 400 is 1.8 mm. This thickness ensures a tight fit between the first flange 201 and the outer sound insulation cotton 100, thereby reducing noise leakage from the connection between the first bonding portion 300 and the second bonding portion 400. Furthermore, the first bonding portion 300 and the second bonding portion 400 within this thickness range also balance strength and durability.

[0055] In some embodiments, the combined thickness of the first bonding portion 300 and the second bonding portion 400 is 2.2 mm. This thickness ensures a tight fit between the first flange 201 and the outer sound insulation cotton 100, thereby reducing noise leakage from the connection between the first bonding portion 300 and the second bonding portion 400. Furthermore, the first bonding portion 300 and the second bonding portion 400 within this thickness range also balance strength and durability.

[0056] In some embodiments, the sum of the thicknesses of the first bonding portion 300 and the second bonding portion 400 is 1.8 to 2.2 mm. This thickness range ensures a tight fit between the first flange 201 and the outer sound insulation cotton 100, thereby reducing noise leakage from the connection between the first bonding portion 300 and the second bonding portion 400. Furthermore, the thickness range of the first bonding portion 300 and the second bonding portion 400 also balances strength and durability. If the sum of the thicknesses is less than 1.8 mm, the first bonding portion 300 and the second bonding portion 400 will be too thin, resulting in lower structural strength, and the adhesive coating or the interconnecting parts will be too thin, leading to poor connection effect and strength.

[0057] If the sum of the thicknesses is greater than 2.2 mm, it will result in excessive thickness, increasing material costs, and noise will easily leak through the connection between the first bonding part 300 and the second bonding part 400, leading to sound leakage.

[0058] In addition, this application also provides an outdoor air conditioning unit, which includes a housing; the housing is the mounting base for the outdoor fan, and its main function is to provide installation and protection for internal components such as the compressor, outdoor heat exchanger and outdoor fan, and to prevent external physical damage or environmental interference.

[0059] In some embodiments, the outdoor unit of the air conditioner further includes a compressor disposed within a housing. The compressor is used to compress a low-temperature, low-pressure refrigerant to a high-temperature, high-pressure refrigerant and then output it.

[0060] In some embodiments, the outdoor unit of the air conditioner also includes an outdoor heat exchanger for exchanging heat between the refrigerant inside it and the outside air.

[0061] In some embodiments, the outdoor unit of the air conditioner also includes an outdoor fan, which is used to blow airflow toward the outdoor heat exchanger, thereby improving the heat exchange effect of the outdoor heat exchanger.

[0062] In some embodiments, the outdoor unit of the air conditioner also includes a sound insulation component disposed within the housing. The sound insulation component is used to reduce the noise of the compressor, thereby achieving noise reduction and improving the user experience.

[0063] In some embodiments, the sound insulation component includes an outer sound insulation cotton 100, the top of which is open; the outer sound insulation cotton 100 is fitted with a compressor; and the edge of the outer sound insulation cotton 100 is bent with a second flange.

[0064] In some embodiments, the sound insulation component includes a top sound insulation cotton 200 disposed on top of the outer sound insulation cotton 100, which is used to close the top opening of the outer sound insulation cotton 100.

[0065] In some embodiments, the sound insulation component includes a third fitting portion and a fourth fitting portion. The third fitting portion is fitted to the second flange, and the extension direction of the third fitting portion is arranged along the extension direction of the second flange. The fourth fitting portion is disposed on the top sound insulation cotton 200, and the extension direction of the fourth fitting portion is arranged along the edge of the top sound insulation cotton 200; the third fitting portion is used to connect with the fourth fitting portion.

[0066] The second flange of the outer sound insulation cotton 100 can be bent and overlapped with the top sound insulation cotton 200 to completely cover and seal the gap between the outer and top sound insulation cotton 100. A third fitting part is located on the second flange and connects with a fourth fitting part on the top sound insulation cotton 200, thus connecting the top and outer sound insulation cotton 100. This connection further seals the gap between the second flange and the top sound insulation cotton 200, reducing the possibility of noise leakage. This design significantly reduces noise emissions from the outdoor unit of the air conditioner, improving the comfort of the surrounding environment. Its noise reduction advantage is particularly pronounced at night or in quiet areas, helping air conditioning products meet higher environmental standards and enhancing market competitiveness.

[0067] The difference between this solution and the solution described above lies in the position of the flange. It is understood that the first seam 203, the second seam 204, the third seam, and the limitations on thickness and size in the solution described above can be adapted to the second flange, the third bonding part, and the fourth bonding part.

[0068] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
