Description

Technical Field

[0001] This application belongs to the field of air conditioner technology, and particularly relates to sound-absorbing structures and air conditioners. Background Technology

[0002] During operation, the outdoor unit of an air conditioner typically generates transmitted noise due to refrigerant pulsation caused by the compressor's compression of the refrigerant. In related technologies, a silencer is installed on the piping system of the outdoor unit to reduce this transmitted noise. However, with the miniaturization of outdoor units, the space for piping within the unit is limited, making it difficult to install a silencer on the piping system, resulting in poor noise reduction.

[0003] Therefore, improvements to existing technologies are necessary.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0027] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0028] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] This application provides a sound-absorbing structure and an air conditioner to solve the problem of poor sound absorption in piping systems due to the difficulty in installing silencers. The following description will be provided in conjunction with the accompanying drawings.

[0031] Please see Figure 1 and Figure 2 This application provides a noise reduction structure, including a pipe body 1 and a noise reduction mechanism 2. The pipe body 1 has at least one mounting hole, and the noise reduction mechanism 2 includes at least one noise reduction component. The at least one noise reduction component passes through the at least one mounting hole, extends into the inside of the pipe body 1, and is fixedly connected to the pipe body 1.

[0032] By opening mounting holes on the pipe body 1 that transports refrigerant, the silencer assembly can be installed inside the pipe body 1 through the mounting holes, thereby reducing the noise of the refrigerant inside the pipe body 1. Since the silencer mechanism 2 is set on the pipe body 1 that transports refrigerant, it does not need to occupy additional pipe running space, thus solving the problem of poor silencer effect of the pipeline system due to the difficulty in installing silencers on the pipeline system.

[0033] Please see Figure 2 and Figure 3 In this embodiment, the silencing mechanism 2 includes a first silencing component 21 and a second silencing component 22. The tube body 1 is cylindrical. A first mounting hole 11 and a second mounting hole 12 are provided on the side wall of the tube body 1. The first mounting hole 11 and the second mounting hole 12 are directly opposite each other. The first silencing component 21 passes through the first mounting hole 11, and the second silencing component 22 passes through the second mounting hole 12.

[0034] Please see Figure 2 and Figure 3Specifically, the first silencing component 21 includes a first base 211 and a first silencing element 212, with the first silencing element 212 disposed on the first base 211. The second silencing component 22 includes a second base 221 and a second silencing element 222, with the second silencing element 222 disposed on the second base 221. The first base 211 passes through a first mounting hole 11, and the first silencing element 212 is disposed inside the pipe body 1. The second base 221 passes through a second mounting hole 12, and the second silencing element 222 is disposed inside the pipe body 1. The first silencing element 212 and the second silencing element 222 are disposed opposite to each other, forming a resonant cavity 3 between them. In this embodiment, the first silencing element 212 is made of any one of metal, porous ceramic, or PVC plastic, and the second silencing element 222 is made of any one of metal, porous ceramic, or PVC plastic.

[0035] Please see Figure 3 and Figure 4 A first pipe seat 13 and a second pipe seat 14 are fixedly connected to the side wall of the pipe body 1. The first pipe seat 13 and the second pipe seat 14 are symmetrically arranged. A first mounting hole 11 passes through the first pipe seat 13, and a second mounting hole 12 passes through the second pipe seat 14. The first base 211 includes a first cover plate 2111 and a first seat body 2112. The first cover plate 2111 abuts against the first pipe seat 13, and the first seat body 2112 passes through the first mounting hole 11. A first silencing component 212 is fixedly connected to the side of the first seat body 2112 away from the first cover plate 2111. The second base 221 includes a second cover plate 2211 and a second seat body 2212. The second cover plate 2211 abuts against the second pipe seat 14, and the second seat body 2212 passes through the second mounting hole 12. A second silencing component 222 is fixedly connected to the side of the second seat body 2212 away from the second cover plate 2211.

[0036] Please see Figure 3 and Figure 4The first silencing component 212 includes a first silencing plate 2121, a first sound-absorbing plate 2122, and a first connecting block 2123. The second silencing component 222 includes a second silencing plate 2221, a second sound-absorbing plate 2222, and a second connecting block 2223. The first connecting block 2123 is fixedly connected to the first base 2112. The first sound-absorbing plate 2122 is arranged along a second direction, and one side of the first sound-absorbing plate 2122 is fixedly connected to the first connecting block 2123. The first silencing plate 2121 is integrally formed on one end of the first sound-absorbing plate 2122 and is arranged along a first direction. The second connecting block 2223 is fixedly connected to the second base 2212. The second sound-absorbing plate 2222 is arranged along a second direction, and one side of the second sound-absorbing plate 2222 is fixedly connected to the second connecting block 2223. The second silencing plate 2221 is integrally formed on one end of the second sound-absorbing plate 2222 and is arranged along a second direction. The arrangement of the first connecting block 2123 is conducive to the first silencing plate 2122 vibrating after receiving pulse energy, and the arrangement of the second connecting block 2223 is conducive to the second silencing plate 2222 vibrating after receiving pulse energy.

[0037] It should be noted that in this embodiment, the first direction is the radial direction of the pipe, and the second direction is the axial direction of the pipe.

[0038] Please see Figure 3 and Figure 4 The first silencing plate 2121 and the second silencing plate 2221 are spaced apart, and the first silencing plate 2122 and the second silencing plate 2222 are also spaced apart. Together, they form a resonant cavity 3. A first inlet 4 for pulsed energy to enter the resonant cavity 3 is formed between the first silencing plate 2121 and the second silencing plate 2222, and a second inlet 5 for pulsed energy to enter the resonant cavity 3 is formed between the second silencing plate 2221 and the first silencing plate 2122. After the pulsating energy enters the resonant cavity 3 through the first inlet 4 or the second inlet 5, the pulsating energy causes the gaseous refrigerant within the resonant cavity 3 to resonate, thereby dissipating the noise-causing pulsating energy within the resonant cavity 3, thus achieving noise reduction.

[0039] In this embodiment, the resonant cavity 3 is a Helmholtz resonant cavity. The gaseous refrigerant in the resonant cavity 3 has a fixed frequency characteristic. By adjusting the distance between the first silencing plate 2121 and the second silencing plate 2221 and the distance between the first silencing plate 2122 and the second silencing plate 2222, the fixed frequency of the gaseous refrigerant in the resonant cavity 3 can be adjusted to be close to the frequency of the pulse energy in the pipe. This allows the pulsating energy to better induce the gaseous refrigerant in the resonant cavity 3 to resonate, thereby improving the noise reduction effect of the silencing mechanism 2.

[0040] This application also provides an air conditioner that includes the sound-absorbing structure described above. Since this air conditioner has the aforementioned sound-absorbing structure, it possesses at least some or all of the beneficial effects of the sound-absorbing structure, which will not be elaborated upon here.

[0041] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0042] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
