[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-5 The multi-chamber air conditioner silencer shown includes a housing 1. A splitting mechanism 2 is installed on both sides of the housing 1. A silencer 3 is installed in the inner cavity of the housing 1. The splitting mechanism 2 facilitates the disassembly of the housing 1 to clean and maintain the silencer 3. The inner cavity of the housing 1 is divided into multiple chambers by the silencer 3. The multiple chambers can play a role in silencing. The housing 1 includes an upper soundproof cover 101 and a lower soundproof cover 102. The upper soundproof cover 101 and the lower soundproof cover 102 are fixed together by the splitting mechanism 2. Both ends of the upper soundproof cover 101 and the lower soundproof cover 102 are fixedly connected to a connecting plate 103.

[0025] The splitting mechanism 2 on both sides of the enclosure 1 can separate the upper soundproof cover 101 from the lower soundproof cover 102, thereby opening the enclosure 1. The silencing device 3 inside the enclosure 1 divides the inner cavity into multiple chambers. When the noise generated by the air conditioner enters the enclosure 1, the sound waves are reflected, interfered with and absorbed in the multiple chambers, thereby achieving the purpose of silencing.

[0026] The splitting mechanism 2 facilitates the cleaning and maintenance of the silencer 3, solving the problem of difficult maintenance of traditional silencers. The design of multiple chambers can effectively handle noise of different frequencies and improve the silencing effect. The design of the upper soundproof cover 101, the lower soundproof cover 102 and the connecting plate 103 facilitates the installation with other components of the air conditioning system and enhances the installation adaptability.

[0027] The splitting mechanism 2 includes a connecting block 21, which is fixed to the two side walls of the upper soundproof cover 101 and the lower soundproof cover 102 respectively. The outer cover of the connecting block 21 is provided with a limiting plate 22. The corresponding positions on the limiting plate 22 and the connecting plate 103 are provided with through holes 23 from left to right. The inner cavity of the through hole 23 is connected by fasteners 24 through threads.

[0028] In the disassembly mechanism 2, the connecting block 21 is fixed to the side wall of the upper soundproof cover 101 and the lower soundproof cover 102. The limiting plate 22 covers the outside of the connecting block 21. After the through hole 23 on the limiting plate 22 and the connecting plate 103 are aligned, they are connected by fastener 24 (bolt) thread to realize the fixed connection of the upper soundproof cover 101 and the lower soundproof cover 102. Similarly, when disassembling, the limiting plate 22 can be separated by unscrewing the fastener 24, so that the upper soundproof cover 101 and the lower soundproof cover 102 can be disassembled.

[0029] This splitting mechanism 2 connection method is simple and reliable, and facilitates quick disassembly and assembly, reducing the operational difficulty of muffler maintenance; the threaded connection method can ensure the stability of the connection under the vibration environment of air conditioning operation, and enhance the overall structural reliability of the muffler.

[0030] The inner cavities of the upper soundproof cover 101 and the lower soundproof cover 102 are fixedly connected with positioning posts 4 at positions corresponding to the silencing device 3. Positioning holes 5 are opened at the top and bottom of the silencing device 3 at positions corresponding to the positioning posts 4.

[0031] The positioning pins 4 inside the upper soundproof cover 101 and the lower soundproof cover 102 cooperate with the positioning holes 5 on the silencing device 3. When installing the silencing device 3, the positioning pins 4 are inserted into the positioning holes 5 to accurately fix the position of the silencing device 3 in the box 1 and ensure that the silencing device 3 is stably installed.

[0032] The cooperation between the positioning column 4 and the positioning hole 5 makes the installation of the muffler 3 more precise, avoiding the impact of installation deviation on the muffler effect; it ensures that the muffler 3 is stable in the housing 1, preventing it from shifting during the vibration of the air conditioner, and further improving the reliability and stability of the muffler.

[0033] The silencing device 3 includes two fixing frames 31 and a fixing plate 32. The two fixing frames 31 are distributed at both ends of the housing 1, and the fixing plate 32 is disposed between the two fixing frames 31. The fixing frames 31 are provided with a first silencing component 33 and the fixing plate 32 is provided with a second silencing component 34.

[0034] The silencing device 3 consists of two fixed frames 31, a fixed plate 32, a first silencing component 33, and a second silencing component 34. The fixed frames 31 are distributed at both ends of the enclosure 1, and the fixed plate 32 is set between the two fixed frames 31. The first silencing component 33 is installed on the fixed frame 31, and the second silencing component 34 is installed on the fixed plate 32. Together, they absorb and process the noise entering the enclosure 1. The multiple components work together to achieve targeted silencing of noise at different frequencies.

[0035] It can effectively process noise of different frequencies and further optimize the noise reduction effect. The modular noise reduction device 3 is easy to install, disassemble and maintain, reducing the maintenance difficulty of the noise reduction device 3.

[0036] The noise reduction assembly 33 includes a honeycomb panel 331, which is installed on two symmetrical sides of a fixing frame 31. A noise reduction plate 332 is snapped onto a symmetrical position on the inner side wall of the fixing frame 31 by a snap-fit ​​member 333. The noise reduction plate 332 is set at an angle.

[0037] In the noise reduction component 33, the honeycomb panel 331 is installed on both sides of the fixing frame 31. The honeycomb structure is used to reflect and absorb sound waves multiple times. The inclined noise reduction plate 332 is snapped into the inner wall of the fixing frame 31 by the snap-fit ​​piece 333. During the propagation process, the sound waves come into full contact with the honeycomb panel 331 and the inclined noise reduction plate 332. After multiple reflections, interferences and absorptions, the noise intensity is reduced. The surface of the noise reduction plate 332 is provided with multiple holes. The noise reduction plate 332 is a prior art product and can be purchased on the market.

[0038] The combination of honeycomb panel 331 and inclined sound-absorbing plate 332 increases the contact area between sound waves and sound-absorbing material, extends the sound wave propagation path, and can absorb and process noise more efficiently, significantly improving sound absorption efficiency. The inclined sound-absorbing plate 332 can also optimize the airflow path and reduce airflow resistance.

[0039] The second noise reduction component 34 includes a fixing ring 341, which is embedded in the center of the fixing plate 32. The fixing ring 341 has multiple recesses 342 distributed around its inner cavity.

[0040] In the second noise reduction component 34, the fixing ring 341 is embedded in the center of the fixing plate 32. The multiple recesses 342 around its inner cavity allow sound waves to enter the recesses 342 and be reflected multiple times inside, consuming sound energy and achieving the absorption and attenuation of noise. Together with other noise reduction components, it completes the noise reduction work.

[0041] The design of the fixed ring 341 and the recessed hole 342 increases the diversity of the silencing structure, which can effectively process noise at specific frequencies and further improve the silencer's ability to suppress broadband noise; the recessed hole 342 structure helps to optimize airflow distribution and ensure smooth airflow.

[0042] The snap-fit ​​component 333 includes multiple sets of limiting blocks 3331, which are distributed on the top and bottom of the fixing frame 31. A limiting groove is formed between two adjacent limiting blocks 3331 for snapping the sound-absorbing plate 332. A slot 3332 is opened on the top of the end of the sound-absorbing plate 332 away from the limiting block 3331. A locking rod 3333 that is snapped into the slot 3332 is engaged with the fixing frame 31.

[0043] The limiting blocks 3331 of the snap-fit ​​component 333 are distributed on the top and bottom of the fixed frame 31. The limiting groove formed by the adjacent limiting blocks 3331 is used to snap the silencing plate 332. The slot 3332 at the top of one end of the silencing plate 332 cooperates with the snap rod 3333. The snap rod 3333 is snapped onto the fixed frame 31, thereby firmly installing the silencing plate 332 on the fixed frame 31 and ensuring that the silencing plate 332 is in a stable position during the silencing operation.

[0044] This snap-fit ​​method is convenient and quick to install, making it easy to install, disassemble and replace the muffler plate 332, reducing the maintenance difficulty of the muffler plate 332; the stable snap-fit ​​structure can ensure that the muffler plate 332 remains stable in the vibration environment of air conditioning operation, avoiding the impact of the muffler plate 332 loosening on the muffler effect, and enhancing the overall stability of the muffler performance.

[0045] In practical use, when using this multi-chamber air conditioner muffler, the upper soundproof cover 101 and the lower soundproof cover 102 are first separated by the splitting mechanism 2 on both sides of the housing 1. Using the precise fit of the positioning post 4 and the positioning hole 5, the muffler device 3 is securely installed inside the housing 1. Then, the upper soundproof cover 101 and the lower soundproof cover 102 are fixedly connected by the connecting block 21, the limiting plate 22, and the fastener 24. The connecting plates 103 at both ends of the muffler are used for installation and docking with other components of the air conditioning system. During operation, the noise generated by the air conditioner enters the housing 1, and the multiple chambers separated by the muffler device 3... The silencer components 33 and 34 work together to reduce noise. The honeycomb panel 331, the inclined silencer plate 332, the fixing ring 341, and the concave hole 342 reflect, interfere with, and absorb sound waves multiple times, reducing noise intensity. At the same time, the inclined silencer plate 332 and the concave hole 342 optimize the airflow path, reduce resistance, and ensure the efficient operation of the air conditioning system. When maintenance is required, the housing 1 can be disassembled by unscrewing the fastener 24 (bolt), making it convenient and quick to clean or replace the silencer device 3, reducing maintenance difficulty and ensuring that the silencer can maintain a good silencing effect for a long time.
