Description

Technical Field

[0001] This utility model relates to the field of oxygen-generating air conditioning technology, specifically to a noise reduction component, an oxygen-generating device, and an air conditioner. Background Technology

[0002] Currently, as users' demand for healthy air quality grows stronger, air conditioners are no longer limited to traditional cooling and heating functions. In order to improve users' quality of life, many air conditioners are also equipped with oxygen generation functions.

[0003] Most existing oxygen-generating air conditioners use air compressors and molecular sieves to produce oxygen. However, air compressors generate significant noise during operation, which is transmitted to the indoor unit through the oxygen production pipeline, thus affecting user comfort.

[0004] Existing technologies for silencing air compressors mostly involve placing sound-absorbing materials such as sound-absorbing cotton at pipe connections or oxygen inlets and outlets. However, this method results in a small contact area between the airflow and the sound-absorbing material, leading to poor silencing effect. Furthermore, using silencers for silencing involves complex piping arrangements between various airflow inlets and outlets, and these pipes are easily moved by the suction force of the air compressor's cooling fan. This not only reduces the service life of the pipes but also decreases the assembly efficiency of the silencer. Utility Model Content

[0010] Furthermore, the silencing assembly also includes: a positioning component disposed on the first silencing body and / or the second silencing body, the positioning component being provided with a slot for engaging the connecting air pipe of the first silencing body and / or the second silencing body.

[0011] Furthermore, the muffler assembly also includes an air inlet connector and an air outlet connector, which are respectively connected to the first muffler cavity. The air inlet connector and the air outlet connector are both located at the end of the first muffler body that is away from the second muffler body.

[0012] Furthermore, the silencing assembly also includes: a partition disposed within the first silencing cavity to divide the first silencing cavity into a first channel and a second channel, an air inlet connector communicating with the first channel, an air outlet connector communicating with the second channel, and at least a portion of the first channel and the second channel communicating through the second silencing cavity.

[0013] Furthermore, the partition is provided with connecting holes, the two ends of which are connected to the first channel and the second channel respectively; there are multiple connecting holes, which are spaced apart.

[0014] Furthermore, the silencing assembly also includes: an extension bracket disposed on the second silencing body at one end away from the first silencing body, the extension bracket being provided with a mounting hole for mounting a target pipe fitting.

[0015] According to a second aspect of the present invention, an oxygen generating device is provided, comprising an air compressor and a silencing component, wherein the air compressor is connected to the silencing component, and the silencing component is the aforementioned silencing component.

[0016] According to a third aspect of this utility model, an air conditioner is provided, including a body, an oxygen generating device, and a noise reduction component.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] As mentioned in the background section, the core components of existing oxygen-generating air conditioners are air compressors and molecular sieves. The air compressor draws in air, and the molecular sieves decompose the air into oxygen and exhaust gas. However, the air compressor generates significant noise during operation, which is transmitted to the indoor unit through the oxygen production pipeline, affecting user comfort. Current technologies for silencing the air compressor mostly involve placing sound-absorbing materials such as sound-absorbing cotton at pipe connections or oxygen inlets and outlets. However, this method results in a small contact area between the airflow and the sound-absorbing material, leading to poor noise reduction. Furthermore, using silencers for noise reduction involves complex piping arrangements between the various airflow inlets and outlets, and these pipes are easily moved by the suction force of the air compressor's cooling fan, reducing both the lifespan of the piping and the assembly efficiency of the silencer. Therefore, to address the aforementioned technical problems, the noise reduction component provided in this application includes a first noise reduction body 110 and a second noise reduction body 120. The first noise reduction body 110 and the second noise reduction body 120 are detachably connected. A first noise reduction cavity 111 is provided inside the first noise reduction body 110, and a second noise reduction cavity 121 is provided inside the second noise reduction body 120. The first noise reduction cavity 111 and the second noise reduction cavity 121 are in communication. A mounting base 130 is provided on the first noise reduction body 110, and the first noise reduction body 110 is mounted on the target workstation via the mounting base 130. The mounting base 130 and the first noise reduction body 110 are integrally formed. The noise reduction component adopts a dual-cavity design, namely the first noise reduction cavity 111 and the second noise reduction cavity 121. When airflow passes through the two noise reduction cavities, its energy and noise can be more effectively absorbed and reduced, thereby providing a quieter working environment. This design increases the contact area between the airflow and the sound-absorbing material, significantly improving the noise reduction effect compared to a single noise reduction cavity or simply using sound-absorbing cotton. The detachable connection design between the first muffler body 110 and the second muffler body 120 allows for convenient assembly and disassembly during production and maintenance, reducing assembly difficulty and improving assembly efficiency. Meanwhile, the mounting base 130 and the first muffler body 110 are integrally molded, reducing additional connecting parts and assembly steps, further simplifying the overall assembly process.

[0037] By designing and mounting the base 130 on the first silencer body 110 and directly installing it at the target workstation, structural instability caused by pipeline movement can be avoided. Furthermore, the one-piece molded base and silencer body structure are more stable and less prone to loosening due to vibration or external forces, enhancing the reliability and durability of the entire system.

[0038] Please refer to Figures 1 to 4This application provides a noise reduction component, including: a first noise reduction body 110, wherein a first noise reduction cavity 111 is disposed within the first noise reduction body 110; a second noise reduction body 120, wherein a second noise reduction cavity 121 is disposed within the second noise reduction body 120, the first noise reduction body 110 and the second noise reduction body 120 are detachably connected, and the first noise reduction cavity 111 and the second noise reduction cavity 121 communicate with each other; and a mounting base 130 disposed on the first noise reduction body 110, wherein the first noise reduction body 110 is mounted on a target workstation via the mounting base 130; wherein the mounting base 130 and the first noise reduction body 110 are integrally formed structures.

[0039] The noise reduction assembly provided in this application includes a first noise reduction body 110, a second noise reduction body 120, and a mounting base 130. The first noise reduction body 110 has a first noise reduction cavity 111, and the second noise reduction body 120 has a second noise reduction cavity 121. The first noise reduction body 110 and the second noise reduction body 120 are detachably connected, and the first noise reduction cavity 111 communicates with the second noise reduction cavity 121. The mounting base 130 is disposed on the first noise reduction body 110, and the first noise reduction body 110 is installed on the target workstation through the mounting base 130. The mounting base 130 and the first noise reduction body 110 are integrally formed structures.

[0040] By employing a dual-cavity silencing design—a first silencing cavity 111 and a second silencing cavity 121—the noise is attenuated multiple times as the airflow passes through the two consecutive silencing cavities, thus achieving a more efficient silencing effect. Compared to a single silencing cavity structure, this design can more comprehensively and deeply absorb and reduce the energy of sound waves, especially performing better in handling high-frequency noise.

[0041] The detachable connection between the first muffler body 110 and the second muffler body 120 makes assembly extremely flexible and quick, while also facilitating later maintenance and upgrades. The one-piece molded mounting base 130, combined with the first muffler body 110, eliminates the need for additional connectors and complex assembly steps, significantly shortening the production cycle and reducing labor costs.

[0042] The one-piece molded mounting base 130 and the first silencing body 110 ensure the overall strength and rigidity of the assembly, reducing the risk of noise or structural damage caused by vibration during operation. This design enables the silencing assembly to maintain good performance and stability in various environments, extending its service life.

[0043] Specifically, the silencing assembly further includes a fixing component 140, at least a portion of which is disposed on the first silencing body 110 and / or the second silencing body 120. The fixing component 140 is used to connect with the connecting air pipe of the first silencing body 110 and / or the second silencing body 120 to fix the connecting air pipe.

[0044] The fixing component 140 effectively secures the connecting air pipe, preventing it from shaking or shifting due to vibrations during air conditioner operation or the suction effect of the fan. This not only reduces noise caused by loose air pipes but also ensures the continuity and efficiency of airflow transmission, making the air conditioning system operate more stably.

[0045] By reinforcing the air pipe with the fixing component 140, wear, deformation, or even breakage of the air pipe caused by external factors (such as vibration, pressure, temperature changes, etc.) can be prevented during long-term operation, thereby protecting the core components of the air conditioning system and extending the service life of the entire system.

[0046] The fixed component 140 helps to standardize the layout of the gas pipes, making them neater and more orderly, and avoiding wasted internal space caused by cluttered gas pipes. An optimized internal space layout improves the overall design of the air conditioner and also facilitates the installation and maintenance of other components.

[0047] In a specific implementation, the fixing component 140 includes: a first fixing member 141, which is disposed on the first silencing body 110. The first fixing member 141 protrudes relative to the outer wall of the first silencing body 110 and is provided with a first fixing hole 1410; and a first binding member, which is sleeved on the connecting air pipe and passes through the first fixing hole 1410 and is connected to the first fixing member 141 to fix the connecting air pipe on the first fixing member 141.

[0048] The first fixing member 141 protrudes from the outer wall of the first silencer body 110 and is designed with a first fixing hole 1410, which allows the air pipe to be precisely positioned on the first fixing member 141 through the first binding member. This fixing method is more secure than the traditional adhesive or free suspension method, and can effectively prevent the air pipe from shaking or falling off during the operation of the air conditioner, thereby improving the stability and reliability of the entire system.

[0049] The combined use of the first fastener 141 and the first binding member helps to isolate the air pipe from direct contact with other components of the air conditioner, thereby reducing the transmission of vibration and lowering the noise caused by air pipe vibration.

[0050] The fixing component 140 further includes: a second fixing member 142, which is disposed on the mounting base 130 and located on the side of the first silencer body 110, and the second fixing member 142 is provided with a second fixing hole 1420; and a second binding member, which is sleeved on the connecting air pipe and passes through the second fixing hole 1420 and is connected to the second fixing member 142 to fix the connecting air pipe on the second fixing member 142.

[0051] The second fixing member 142 is located on the mounting base 130 and adjacent to the side of the first silencer body 110. This positioning ensures that the connecting air tube is securely fixed at the position closest to the silencer body. The second binding member is sleeved on the connecting air tube and then passes through the second fixing hole 1420 to connect with the second fixing member 142, forming a strong mechanical lock. This effectively prevents the air tube from shifting due to vibration or external force, enhancing the stability of the air tube and the reliability of the entire system.

[0052] By setting the second fixing hole 1420, the connecting air tube can be quickly positioned and fixed by the second binding piece, without the need for cumbersome manual adjustment and additional fixing methods.

[0053] A securely fixed air tube helps optimize airflow management and reduces additional noise caused by air tube vibration. Furthermore, a stable, fixed air tube prevents airflow obstruction due to twisting or deformation, further reducing operating noise and optimizing the user experience.

[0054] Fixing the air tube not only prevents it from shifting, but more importantly, for oxygen-generating air conditioners, it effectively avoids the risk of oxygen leakage, improves the safety performance of the entire air conditioning system, and protects the life and property safety of users.

[0055] In this application, the silencing assembly further includes: a positioning component 150, disposed on the first silencing body 110 and / or the second silencing body 120, wherein the positioning component 150 is provided with a slot 151 for engaging the connecting air pipe of the first silencing body 110 and / or the second silencing body 120.

[0056] The design of the slot 151 allows the connecting air tube to be quickly positioned and fixed through a simple "click" action, without the need for complicated adjustments or tools, which greatly improves the speed and accuracy of installation and reduces airflow obstruction or noise problems caused by installation errors.

[0057] The slot 151 on the positioning component 150 provides a solid support point for the connecting air tube, ensuring its stability even during vibrations caused by air conditioning operation, preventing it from easily moving or becoming loose. This not only reduces noise caused by air tube movement but also lowers the risk of air tube damage and extends its service life.

[0058] By precisely positioning the air duct using the positioning component 150, it can be ensured that the airflow passes through the silencer assembly along the optimal path. Combined with the fixing component 140 fixing the connecting air duct, unnecessary airflow detours and turbulence are avoided, thereby improving the silencer effect and reducing the noise level during air conditioning operation.

[0059] In the specific implementation process, the noise reduction assembly also includes an air inlet connector 161 and an air outlet connector 162, which are respectively connected to the first noise reduction cavity 111. The air inlet connector 161 and the air outlet connector 162 are both located at the end of the first noise reduction body 110 away from the second noise reduction body 120.

[0060] By placing the air inlet 161 and outlet 162 at opposite ends of the silencer body, the path of the gas within the silencer cavity is extended. This means that the gas has more opportunities to contact the sound-absorbing material as it passes through the first silencer cavity 111, thus absorbing noise more effectively. Compared to traditional designs, this layout significantly improves silencer efficiency and provides a quieter operating environment.

[0061] The air inlet connector 161 and air outlet connector 162 are directly integrated into the muffler body, eliminating the need for additional piping and simplifying the component installation process. On the production line, this can greatly improve assembly speed, reduce assembly errors, thereby lowering production costs and improving overall production efficiency.

[0062] By centralizing the air intake and exhaust connections at one end of the silencer body, the internal structural layout of the air conditioner is optimized, saving valuable installation space. This is particularly advantageous for miniaturized, compact air conditioner designs, enabling more efficient gas handling and noise reduction within limited space.

[0063] Integrating the air inlet connector 161 and the air outlet connector 162 into one end of the first silencer body 110 not only optimizes the airflow path and improves the silencing effect, but also simplifies installation and maintenance, and enhances system integration and safety.

[0064] like Figure 4 As shown, the silencing assembly also includes: a partition 170 disposed in the first silencing cavity 111 to divide the first silencing cavity 111 into a first channel 1110 and a second channel 1111; an air inlet connector 161 is connected to the first channel 1110; an air outlet connector 162 is connected to the second channel 1111; and at least a portion of the first channel 1110 and the second channel 1111 are connected through the second silencing cavity 121.

[0065] The partition 170 requires the airflow to pass through the first channel 1110, then through the second channel 1111, and finally through the second silencing cavity 121. This multi-stage channel design increases the path length and complexity of the airflow, which is beneficial for the sound waves to be reflected and absorbed multiple times in the channel, thereby significantly enhancing the silencing effect.

[0066] By separating the airflow into two different channels, the airflow can be distributed more evenly, reducing the concentration of airflow in a certain area and avoiding noise caused by excessively high local airflow speed. At the same time, the baffle 170 can also buffer the airflow, reducing the degree of airflow turbulence and further optimizing the operating efficiency of the noise reduction component.

[0067] The cooperation between the partition 170 and the first channel 1110 and the second channel 1111, as well as the final connection through the second silencing cavity 121, not only improves the silencing effect, but also enhances the airtightness and stability of the system, avoiding energy loss caused by airflow short circuits or leaks.

[0068] The ingenious design of the partition 170 allows for a more rational division and utilization of the internal space of the first sound-absorbing body 110. This design not only accommodates more sound-absorbing material but also allows for adjustments to the length and shape of the channels according to the internal layout of the air conditioner, thereby optimizing the spatial layout of the entire first sound-absorbing cavity 111.

[0069] Specifically, the partition 170 is provided with a connecting hole 171, the two ends of which are connected to the first channel 1110 and the second channel 1111 respectively; there are multiple connecting holes 171, which are spaced apart.

[0070] The design of multiple connecting holes 171 allows airflow to form multi-stage flow between the first channel 1110 and the second channel 1111. This means that airflow must make multiple turns and change paths to flow from the first channel to the second channel. This multi-path, multi-stage flow design increases the contact area and flow time of airflow inside the silencing component, thereby enhancing the silencing effect and reducing the noise level.

[0071] The interconnecting holes 171 are spaced apart, which allows the airflow to be evenly distributed when passing through the baffle 170, avoiding situations where the local airflow speed is too fast or too slow, and improving the uniformity and balance of airflow transmission.

[0072] The spacing between the connecting holes 171 serves as vibration isolation, reducing resonance caused by airflow. Resonance is a significant factor in noise amplification; reducing resonance effectively suppresses noise generation, making the air conditioner quieter during operation.

[0073] Specifically, the silencing assembly also includes: an extension bracket 180, disposed on the second silencing body 120 at one end away from the first silencing body 110, and the extension bracket 180 is provided with a mounting hole for mounting a target pipe connector.

[0074] The 180° extension bracket design, especially the mounting holes, provides precise installation positions for the target pipe fittings. This means that during installation, the pipe fittings can be directly inserted into the pre-set mounting holes, greatly simplifying the installation process and improving installation speed and accuracy.

[0075] The extension bracket 180 is fixed to the second silencer body 120, which not only increases the stability of the bracket itself, but also enhances the coupling between the pipe joint and the silencer assembly through physical connection. Even when the air conditioner is running for a long time or encounters external vibration, the pipe joint can remain in place and will not easily loosen or fall off, thereby improving the operational reliability and durability of the entire air conditioning system.

[0076] This application also provides an oxygen generating device, including an air compressor 200 and a silencer assembly 100, wherein the air compressor 200 is connected to the silencer assembly 100, and the silencer assembly 100 is the silencer assembly 100 of the above embodiment.

[0077] The silencing component 100 adopts an integrated design, including optimized air inlet and outlet positions, silencing cavity structure, and reasonable layout of internal silencing materials. These designs can effectively reduce the noise generated by the air compressor 200 during operation.

[0078] By using the fixing component 140, the first fixing member 141, and the second fixing member 142, the connecting gas pipe is precisely positioned and securely fixed, reducing pipe wear and leakage caused by vibration or external force, improving the stability and reliability of the entire oxygen generating device, and extending its service life. The synergistic effect of the positioning component 150 and the fixing component 140 reduces the risk of oxygen leakage.

[0079] like Figure 5 As shown, this application also provides an air conditioner, including a body 300, an oxygen generating device and a noise reduction assembly 100. A support plate is provided inside the body 300, and the oxygen generating device and the noise reduction assembly 100 are respectively disposed on the support plate. The mounting base 130 in the noise reduction assembly 100 is connected to the support plate. The noise reduction assembly 100 is the noise reduction assembly 100 of the above embodiment.

[0080] By integrating the oxygen generator and the silencer assembly 100 inside the unit 300 and mounting them together on the support plate, this design greatly improves the integration of the air conditioning system. It reduces external connections and wiring between components, making the entire system more compact and saving installation space.

[0081] The tight connection between the mounting base 130 and the support plate in the silencer assembly 100 ensures smooth airflow between the silencer assembly and the oxygen generator. The mounting base 130 is provided with connection holes 131. The connection between the mounting base 130 and the support plate is typically achieved through a robust fixing method (such as screw fixing). This ensures the stability of the silencer assembly during air conditioning operation and facilitates the assembly and disassembly of the silencer assembly 100 from the support plate, thus improving the assembly efficiency of the silencer assembly 100.

[0082] In this application, the target pipe fitting includes an intake pipe 191 and an oxygen outlet pipe 192. The intake pipe 191 and the oxygen outlet pipe 192 are respectively mounted on the extension bracket 180. During the assembly of the silencer assembly 100, the outdoor unit body 300 is provided with a through hole, through which at least a portion of the intake pipe 191 and the oxygen outlet pipe 192 are inserted. Outdoor air is drawn into the air compressor 200 through the intake pipe 191, and oxygen is delivered to the indoor unit through the oxygen outlet pipe 192. During this process, the installation of the silencer assembly 100 can be positioned by having at least a portion of the intake pipe 191 and the oxygen outlet pipe 192 inserted into the through hole. This facilitates the connection between the mounting base 130 and the support plate during the fixing of the silencer assembly, and also facilitates the connection between the screw post on the side of the first silencer body 110 and the outdoor unit body 300.

[0083] The first silencer body 110 is integrated with the air inlet connector 161, air outlet connector 162, and mounting base 130, reducing the number of screws and improving assembly efficiency. The air inlet connector 161 and air outlet connector 162 are located on the same side, providing better noise reduction. The mounting bracket 151 and wire tie fixing component 140 are provided to fix the connecting wires and ventilation pipes, preventing them from being sucked inwards towards the cooling fan 210.

[0084] To prevent intake noise from being amplified on the indoor unit side, the oxygen generating module has multiple components such as a silencer, oxygen outlet, and air inlet, making assembly relatively complex. The silencer assembly in this application integrates the first silencer body 110 with the air inlet connector 161, air outlet connector 162, and mounting base 130, which can reduce the number of components, further reduce the number of screws, and improve assembly efficiency.

[0085] like Figure 5 The diagram shown is an assembly drawing of the noise reduction component in the complete machine according to this application. The noise reduction component is placed on one side of the air compressor 200, and the side of the air compressor 200 is the cooling fan 210 of the air compressor 200. The cooling fan 210 draws air from the environment into the air compressor for convective heat exchange.

[0086] like Figure 1As shown, the silencing assembly of this application includes a first silencing body 110, a second silencing body 120, a mounting base 130, a fixing component 140, a positioning component 150, an air inlet connector 161, an air outlet connector 162, and an extension bracket 180. The first silencing body 110 and the second silencing body 120 are connected via screw holes, forming the main cavity of the silencer. A gasket is added in the middle to increase sealing, and the length of the cavity can be freely combined according to the available space.

[0087] The air inlet connector 161 and the air outlet connector 162 are located on one side of the first silencer body 110, which can lengthen the airflow path in the cavity and have a better noise reduction effect.

[0088] The intake pipe 191 and the oxygen outlet pipe 192 are integrally formed with the second silencer body 120 on the other side of the first silencer body 110. The intake pipe 191 and the oxygen outlet pipe 192 can also serve as the installation and positioning structure for the silencer assembly. Meanwhile, the upper part of the second silencer body 120 is designed with a slot 151, through which the ventilation pipe and connecting wire can be laid out.

[0089] Furthermore, a first fixing member 141 with wire tie is designed on the first silencing body 110 to further fix the pipeline and power line, prevent them from being excited by vibration and colliding with other structures to cause abnormal noise, and also prevent the reliability from being affected by the air compressor fan.

[0090] The entire silencer assembly is secured by three screws: the lower part of the intake pipe 191 and the oxygen outlet pipe 192 is secured to the body 300 by one screw; the silencer sidewall screw post is secured to the body 300; and the base screw hole is secured to the air compressor chassis. This effectively improves assembly efficiency while ensuring the reliability and aesthetics of the pipe and wiring routing.

[0091] The air compressor chassis is the support plate described in the above embodiment.

[0092] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0093] The noise reduction assembly provided in this application includes a first noise reduction body 110, a second noise reduction body 120, and a mounting base 130. The first noise reduction body 110 has a first noise reduction cavity 111, and the second noise reduction body 120 has a second noise reduction cavity 121. The first noise reduction body 110 and the second noise reduction body 120 are detachably connected, and the first noise reduction cavity 111 communicates with the second noise reduction cavity 121. The mounting base 130 is disposed on the first noise reduction body 110, and the first noise reduction body 110 is installed on the target workstation through the mounting base 130. The mounting base 130 and the first noise reduction body 110 are integrally formed structures.

[0094] By employing a dual-cavity silencing design—a first silencing cavity 111 and a second silencing cavity 121—the noise is attenuated multiple times as the airflow passes through the two consecutive silencing cavities, thus achieving a more efficient silencing effect. Compared to a single silencing cavity structure, this design can more comprehensively and deeply absorb and reduce the energy of sound waves, especially performing better in handling high-frequency noise.

[0095] The detachable connection between the first muffler body 110 and the second muffler body 120 makes assembly extremely flexible and quick, while also facilitating later maintenance and upgrades. The one-piece molded mounting base 130, combined with the first muffler body 110, eliminates the need for additional connectors and complex assembly steps, significantly shortening the production cycle and reducing labor costs.

[0096] The one-piece molded mounting base 130 and the first silencing body 110 ensure the overall strength and rigidity of the assembly, reducing the risk of noise or structural damage caused by vibration during operation. This design enables the silencing assembly to maintain good performance and stability in various environments, extending its service life.
