[0040] This application provides a garment processing device; please refer to [link / reference]. Figures 1 to 4 The garment processing device 100 includes a cylindrical assembly 1 and an exhaust assembly 2. The cylindrical assembly 1 has a garment processing chamber 11 inside. The exhaust assembly 2 includes a housing 21 and an exhaust element. The housing 21 defines an exhaust channel 211 and an air outlet 212. The exhaust channel 211 connects the garment processing chamber 11 and the air outlet 212. The silencer 3 includes an air inlet 316 and an air outlet 312. The air inlet 316 is connected to the air outlet 212, and the air outlet 312 is connected to the outside of the garment processing device 100.

[0041] Clothing processing equipment 100 is a type of equipment specifically designed for performing various processing operations on clothing, including washing, dehydration, and drying. Taking a dryer as an example, in related technologies, the operation mode of a negative pressure drum dryer mainly relies on the operation of an internal fan to generate negative pressure, thereby expelling hot and humid air. During the drying stage, due to the influence of negative pressure, the internal cavity of the dryer is in a relatively sealed state. At this time, the air flow speed is relatively fast, resulting in greater noise during the operation of the dryer.

[0042] The drum assembly 1 refers to the component in the clothing processing equipment 100 that has a clothing processing chamber 11, in which clothing processing operations (such as washing and drying) are carried out, and it is one of the core parts of the equipment.

[0043] The exhaust assembly 2 is a component in the clothing processing equipment 100 responsible for exhausting the air inside the equipment. It consists of multiple parts to achieve air exhaust.

[0044] The housing 21 is the outer shell structure of the exhaust assembly 2, which serves to protect the internal components and limit the space, and defines the exhaust channel 211 and the air outlet 212 to provide a path for air flow.

[0045] For example, the housing 21 may be made of sound-insulating material to further enhance the noise reduction effect of the device.

[0046] The exhaust component is a part in exhaust assembly 2 used to achieve the exhaust function. The specific structure of the exhaust component is not limited here; for example, it can be a fan or other part with an exhaust function, which exhausts air through operation.

[0047] The silencer 3 is a component used to reduce noise generated during the exhaust process. The silencer 3 is provided with an air guide 31 and a silencer 32.

[0048] The exhaust duct 211 is defined by the housing 21 and is an air passage connecting the clothing processing chamber 11 and the air outlet 212, used to guide the air in the clothing processing chamber 11 to the air outlet 212.

[0049] The air vent 212 is an opening formed by the housing 21. Air passes through the exhaust channel 211 and reaches the air vent 212, which is a node in the air flow path.

[0050] The air guide section 31 is part of the silencer 3 and serves to guide airflow. The air guide section 31 has an air guide channel 311, an air outlet 312, and a silencer hole 313, causing the air to flow along a specific path. The silencer section 32 is the part of the silencer 3 that performs the noise reduction function. The silencer section 32 is located on the outer wall of the air guide section 31 and together with the outer wall of the air guide section 31, it defines a silencer cavity 321. Noise reduction is achieved through communication with the air guide channel 311.

[0051] The air guide channel 311 is located inside the air guide section 31, connecting the air inlet 212 and the air outlet 312, guiding air from the air inlet 212 to the air outlet 312, and is the air flow path within the air guide section 31.

[0052] The air outlet 312 and the air inlet 316 are openings on the air guide section 31. Air enters from the air inlet 316, passes through the air guide channel 311, and exits from the air outlet 312. The air inlet 316 is where air flows into the silencer 3. The air outlet 312 is where air flows out of the silencer 3.

[0053] The connection between the air inlet 316 and the air outlet 212, and the connection between the air outlet 312 and the outside of the equipment, together form a complete airflow path from the garment processing chamber 11 to the outside of the equipment. In this path, the silencer 3 intercepts and processes the noise generated during the garment processing inside the equipment, improving the situation where high-noise air is directly discharged into the external environment.

[0054] For example, the silencing part 32 and the air guide part 31 can be made of materials with certain sound absorption properties, such as porous materials or sound-absorbing coatings.

[0055] Negative pressure tumble dryers have a problem with excessive exhaust noise. Currently, the common method for venting tumble dryers involves installing an exhaust connector at the exhaust point. The exhaust outlet of this connector is larger than the inlet, aiming to reduce noise by increasing the airflow discharge area. In related technologies, a silencer 3 is added to the outside of the exhaust duct. The airflow is silenced as it passes through the exhaust duct before being discharged. However, this method is structurally complex and its noise reduction effect is not ideal.

[0056] The clothing processing device 100 provided in this embodiment of the application, by setting an exhaust assembly 2, is used to extract humid air from the clothing processing chamber 11 of the cylindrical assembly 1, and at the same time reduce the pressure inside the clothing processing chamber 11, so as to achieve clothing drying. An air inlet 316 and an air outlet 312 are provided on the silencer 3. By connecting the air outlet 212 of the exhaust assembly 2 to the air inlet 316 of the silencer 3, and the air outlet 312 of the silencer 3 to the outside of the clothing processing device 100, a channel for airflow discharge is formed. That is to say, the silencer 3 forms part of the channel. During the exhaust process of the exhaust assembly 2, the silencer 3 can perform noise reduction treatment on the airflow flowing through the silencer 3, which is beneficial to improve the noise reduction effect during the exhaust process, making the clothing processing device 100 operate more quietly, thereby improving the user experience. In addition, the silencer 3 forming part of the airflow discharge channel also helps to simplify the structure of the airflow channel.

[0057] In some embodiments, please refer to Figures 1 to 4The silencer 3 includes an air guide section 31 and a silencer section 32 disposed on the outer wall of the air guide section 31. The air guide section 31 forms an air guide channel 311, a silencer hole 313, and an air inlet end 316 and an air outlet end 312 located at both ends of the air guide channel 311. The air inlet end 316 is connected to the air outlet 212. A silencer cavity 321 is defined between the silencer section 32 and the outer wall of the air guide section 31. The cavity wall of the air guide channel 311 is provided with a silencer hole 313. The silencer cavity 321 is connected to the air guide channel 311 through the silencer hole 313.

[0058] The silencing hole 313 is a hole that runs through the cavity wall of the air guide channel 311. It is used to connect the silencing cavity 321 and the air guide channel 311, so that the air interacts with the silencing cavity 321 during the flow process to achieve silencing.

[0059] The silencing cavity 321 is a space defined between the outer wall of the silencing part 32 and the air guide part 31. Air enters the silencing cavity 321 through the silencing hole 313, and noise is reduced by utilizing the structure and characteristics of the silencing cavity 321.

[0060] A silencing cavity 321 is formed between the outer walls of the silencing section 32 and the air guide section 31. A silencing hole 313 is provided through the cavity wall of the air guide channel 311, and the silencing cavity 321 is connected to the air guide channel 311 through the silencing hole 313. When sound waves propagate in the air guide channel 311, some sound waves enter the silencing cavity 321 through the silencing hole 313. The sound waves entering the silencing cavity 321 are continuously reflected and refracted within the cavity. Due to the special structure and space of the silencing cavity 321, the path of sound wave propagation within it becomes complex and chaotic, and sound energy is continuously consumed in this process. Simultaneously, the connection between the silencing cavity 321 and the air guide channel 311 through the silencing hole 313 allows sound waves to travel back and forth between the two spaces, further increasing the number of reflections and refractions of the sound waves. More sound energy is converted into heat energy and other forms of energy and dissipated, thereby reducing the intensity of the sound waves and achieving the effect of silencing.

[0061] The combination of the silencing cavity 321 and the silencing hole 313 helps to reduce the noise generated during the exhaust process, making the clothing processing equipment 100 operate more quietly and improving the user experience.

[0062] In some embodiments, please refer to Figures 1 to 4 The silencing part 32 extends circumferentially along the air guide part 31.

[0063] Here, the silencing section 32 extends along the circumference of the air guide section 31 in its spatial layout. That is to say, the silencing section 32 is like a ring structure surrounding the outer wall of the air guide section 31, closely fitting the air guide section 31 and surrounding it for one or part of its circumference. In this way, the silencing section 32 can process the noise carried by the passing airflow in all directions around the air guide section 31, which helps to enhance the coverage and effect of silencing.

[0064] The silencing section 32 extends circumferentially along the air guide section 31, enabling multi-directional noise reduction around the air guide section 31. Since the noise generated when the airflow moves within the air guide section 31 propagates in all directions, the circumferentially extending silencing section 32 can cover the noise source as comprehensively as possible, facilitating the absorption of noise from all directions. Compared to setting the silencing section 32 locally, this improves the efficiency and comprehensiveness of noise reduction.

[0065] In some embodiments, please refer to Figures 5 to 6 The silencing part 32 surrounds the air guide part 31, and the silencing holes 313 are distributed at intervals along the circumference of the air guide part 31. The silencing part 32 and the air guide part 31 define a silencing cavity 321 surrounding the air guide channel 311.

[0066] The silencing part 32 is arranged around the air guide part 31, forming a silencing cavity 321 surrounding the air guide channel 311. When airflow generates noise in the air guide channel 311, the noise sound waves enter the silencing cavity 321 through the silencing holes 313 on the wall of the air guide channel 311. In the silencing cavity 321, the sound waves undergo multiple reflections, interferences, and interactions with the silencing material, and their energy is continuously consumed, thereby achieving the effect of noise reduction.

[0067] Furthermore, the silencing holes 313 are spaced circumferentially along the air guide section 31. When air flows within the air guide channel of the air guide section 31 and generates noise, sound waves propagate in all directions. The silencing holes 313, spaced circumferentially, can capture sound waves from all angles of the air guide section 31. Regardless of the direction in which the sound waves propagate, there is a corresponding silencing hole 313 to allow them to enter the silencing cavity, thereby achieving comprehensive absorption of noise within the entire air guide channel, avoiding situations where local noise is not adequately addressed, and ensuring the uniformity of the silencing effect.

[0068] The specific distance between the silencing holes 313 distributed circumferentially along the air guide 31 is determined according to actual needs and is not limited here.

[0069] In some embodiments, please refer to Figures 5 to 8 The silencing part 32 includes a first sub-part and a second sub-part, which are joined together to form the silencing part 32.

[0070] The first sub-section and the second sub-section are part of the structure of the muffler 32. The first sub-section and the second sub-section together constitute the complete muffler 32. They are combined together by docking to achieve the muffler function.

[0071] The method of connecting the first and second sub-parts is not limited here. For example, it can be a simple flat joint, or it can be a mortise and tenon joint to make the two sub-parts more tightly connected, reduce gaps, and prevent noise leakage. It can also be a magnetic joint to facilitate installation and disassembly, and make it more convenient when maintenance or replacement of some sub-parts is required.

[0072] For example, the first sub-part and the second sub-part are connected by ultrasonic welding.

[0073] The muffler section 32 is assembled from interlocking sub-sections, which offers greater manufacturing flexibility. Different sub-sections can be made using different materials and manufacturing processes as needed, and then assembled. Furthermore, this modular structure reduces the complexity of molding the overall muffler 3 structure, thereby lowering production costs.

[0074] In some embodiments, the silencing part 32 is an integral structure.

[0075] The integrated silencing unit 32, with its absence of seams, offers greater overall structural stability. During equipment operation, especially in environments with high vibration and high airflow impact, it better maintains structural integrity, reducing the likelihood of decreased silencing performance due to structural loosening.

[0076] In some embodiments, please refer to Figures 5 to 8 The sum of the flow cross-sectional areas of all the silencers 313 is S1, and the sum of the surface areas of the area of ​​the air guide 31 corresponding to the silencer cavity 321 is S2. The ratio of S1 to S2 is greater than or equal to 5% and less than or equal to 8%.

[0077] The flow cross-section refers to the cross-sectional area perpendicular to the airflow direction. It determines the amount of fluid passing through this cross-section per unit time and has a significant impact on parameters such as airflow velocity and pressure. In the air guide section 31, changes in the flow cross-sectional area alter the airflow characteristics. For the silencing hole 313, the flow cross-sectional area refers to the cross-sectional area of ​​the silencing hole 313 perpendicular to the airflow or sound wave propagation direction.

[0078] The sum of the cross-sectional areas of all the silencers 313, S1, refers to the total channel area that allows airflow to pass through and enter the silencer cavity 321.

[0079] The shape of the silencing hole 313 is not limited here; for example, it can be circular, square, elliptical, etc. Different shapes of silencing holes 313 may have different flow characteristics and sound wave guidance effects. In actual design, the appropriate shape of the silencing hole 313 can be selected according to the specific silencing requirements and the structure of the air guide 31.

[0080] The surface of the area of ​​the air guide 31 corresponding to the silencing cavity 321 can be specially treated, such as by adding some uneven structures or textures, which can further increase the reflection and scattering of sound waves when entering the silencing cavity 321 and enhance the silencing effect.

[0081] The sum of the surface areas S2 of the area of ​​the air guide 31 corresponding to the silencing cavity 321 refers to the total area of ​​the surface of the part of the air guide 31 that is in contact with the silencing cavity 321.

[0082] The ratio of the sum of the cross-sectional areas S1 of the silencing holes 313 to the sum of the surface areas S2 of the corresponding silencing cavity 321 area of ​​the air guide 31 is limited to a range of greater than or equal to 5% and less than or equal to 8%. For example, it can be 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, etc.

[0083] By controlling the ratio of S1 to S2 within a certain range, an appropriate amount of noise waves can enter the silencing cavity 321 through the silencing hole 313 for processing. If the ratio is too small, insufficient noise may enter the silencing cavity 321, and much noise will not be effectively processed. If the ratio is too large, excessive airflow and noise will directly enter the silencing cavity 321, affecting its normal operation and potentially causing excessive internal pressure, thus reducing the silencing effect. A reasonable ratio range also helps maintain the stability of airflow within the air guide section 31.

[0084] In some embodiments, please refer to Figure 3 The exhaust assembly 2 includes a temperature and humidity sensor 22, which is located in the exhaust duct 211.

[0085] The temperature and humidity sensor 22 is an instrument that can sense and measure the two physical quantities of temperature and humidity in the environment. It converts changes in temperature and humidity into measurable signals such as electrical signals through specific sensing elements, so that relevant equipment or systems can acquire and process these data.

[0086] By monitoring the temperature and humidity data within the exhaust duct 211 in real time using the temperature and humidity sensor 22, the system can adjust parameters such as exhaust speed and frequency to achieve optimal ventilation. Furthermore, understanding the temperature and humidity of the exhaust air helps protect the exhaust assembly 2 and other related equipment. If the exhaust temperature is too high, it may indicate overheating; feedback from the temperature and humidity sensor 22 allows for timely cooling measures to prevent damage from overheating and extend the equipment's lifespan.

[0087] In some embodiments, please refer to Figures 5 to 6 The cross-section of the air guide 31 perpendicular to its axial direction is rectangular.

[0088] Compared to other shapes of air guides 31, the rectangular cross-sectional area of ​​the air guide 31 is larger, which is beneficial to improving the air guiding efficiency of the silencer 3.

[0089] In some embodiments, please refer to Figure 7 The cross-sections of both the air guide section 31 and the silencer section 32 perpendicular to the axial direction of the air guide section 31 are circular, and these two circles are concentric. This design facilitates the molding of the silencer 3 and helps to reduce the production cost of the silencer 3.

[0090] In some embodiments, please refer to Figure 8 The cross-section of the air guide 31 perpendicular to its axial direction is circular, and the cross-section of the silencing part 32 perpendicular to the axial direction of the air guide 31 is also circular, but the two circles are not concentric. The silencing part 32 is biased towards the more open side of the muffler 3 installation space, thereby increasing the volume of the silencing cavity 321 in the silencing part 32 and thus improving the silencing effect of the muffler 3. Of course, the cross-section of the silencing part 32 perpendicular to the axial direction of the air guide 31 can also be other irregular shapes, which can be determined according to the shape of the installation space of the silencing part 32. The principle is to maximize the size of the silencing cavity 321 as much as possible.

[0091] In some embodiments, please refer to Figures 5 to 8 The air guide section 31 includes a first connecting section 314 and a second connecting section 315 connected to each other. The end of the first connecting section 314 away from the second connecting section 315 is connected to the air outlet 212. Along the direction from the first connecting section 314 to the second connecting section 315, the flow cross-sectional area of ​​the first connecting section 314 decreases, while the flow cross-sectional area of ​​the second connecting section 315 remains unchanged. The first connecting section 314 is a component of the air guide section 31, with one end connected to the air outlet 212. After the airflow enters the air guide section 31 from the air outlet 212, it first flows through the first connecting section 314. The reduced flow cross-sectional area of ​​the first connecting section 314 helps to guide the gas to concentrate through the air guide section 31 and enter the subsequent silencer chamber 321 or other processing components, thereby improving exhaust efficiency.

[0092] In some embodiments, a connection structure is provided between the first connecting segment 314 and the air vent 212 to assist the silencer 3 in better connecting to the air vent 212. For example, the connection structure can be a hole-shaft mating structure, with the first connecting segment 314 nested in the air vent 212; alternatively, the first connecting segment 314 can be placed over the outside of the air vent 212 and connected to the air vent 212 by fasteners.

[0093] The second connecting section 315 is interconnected with the first connecting section 314 and is the section through which the airflow subsequently flows in the air guide section 31. In this section, the cross-sectional area of ​​the airflow remains constant. The unchanged cross-sectional area of ​​the second connecting section 315 ensures that the accelerated airflow maintains a stable velocity and pressure, mitigating the turbulence caused by frequent changes in the cross-sectional area. This stable airflow condition is beneficial for the subsequent noise reduction section 32, improving its noise reduction effect.

[0094] In some embodiments, the silencing hole 313 is disposed on the second connecting section 315, the silencing part 32 is disposed around the second connecting section 315, and the silencing part 32 covers the silencing hole 313.

[0095] The silencing hole 313 is located in the second connecting section 315, where airflow is relatively stable. The silencing hole 313 allows sound waves from the air guide channel 311 to enter the silencing cavity 321. The special structure and sound-absorbing material of the silencing cavity 321 absorb, reflect, and scatter the sound waves, effectively reducing noise. The silencing section 32 covers the silencing hole 313, ensuring that as many sound waves as possible enter the silencing cavity 321 through the silencing hole 313, reducing the possibility of noise leakage from other parts and improving the efficiency and accuracy of silencing.

[0096] In addition, the silencing part 32 surrounds and covers the silencing hole 313, which can protect the silencing hole 313, prevent external impurities, dust and other contaminants from entering the silencing hole 313, improve the situation of the silencing hole 313 being blocked, and thus ensure the normal operation of the silencing system and the long-term stable silencing effect.

[0097] In some embodiments, please refer to Figures 1 to 4 The cylindrical assembly 1 includes a back panel 12, and an exhaust assembly 2 is disposed on the back panel 12. The back panel 12 is provided with ventilation holes, which connect the clothing processing chamber 11 and the exhaust channel 211.

[0098] The back plate 12 is a component of the cylindrical assembly 1, usually located at the rear of the equipment or a specific position. The back plate 12 serves to support and enclose the equipment, while also providing a carrier for the installation of other components.

[0099] The ventilation holes are holes opened on the back panel 12. Their function is to establish a connection between the garment processing chamber 11 and the exhaust duct 211, so that air can circulate between the two.

[0100] The shape of the ventilation holes is not limited here. In addition to the common circle, they can also be designed as square, oval or other polygons.

[0101] The connection method between the back panel 12 and the exhaust component 2 is not limited here. In addition to conventional fixed connection methods, such as bolt connection and welding, detachable connection methods, such as snap-fit ​​connection and magnetic connection, can also be used.

[0102] In some embodiments, auxiliary structures such as baffles and filters can be added to the ventilation openings. Baffles guide the airflow, allowing air to flow more smoothly from the garment processing chamber 11 into the exhaust duct 211, reducing airflow turbulence and energy loss. Filters remove impurities and lint from the air, preventing these substances from entering the exhaust duct 211 and affecting the normal operation of the exhaust assembly 2. They also help maintain the cleanliness of the equipment's interior and extend its lifespan.

[0103] By providing ventilation holes on the back panel 12 to connect the garment processing chamber 11 and the exhaust duct 211, a direct and efficient path is provided for the exhaust of air from the equipment. During processes such as drying, humid air can be quickly exhausted, accelerating the drying process of the garments and improving the processing efficiency of the equipment.

[0104] In some embodiments, please refer to Figures 1 to 4 The garment processing equipment 100 includes a housing 4, and a cylindrical assembly 1 is disposed in the housing 4. The housing 4 includes a housing body 41 and a rear cover assembly 42. The housing body 41 is provided with a mounting hole 411, the rear cover assembly 42 is disposed at the mounting hole 411, and a back plate 12 is disposed on the side of the cylindrical assembly 1 near the mounting hole 411. The rear cover assembly 42 is provided with a clearance opening 4211 and an air inlet 4221. The clearance opening 4211 is connected to the air outlet 312. The cylindrical assembly 1 is provided with an air intake device 13, which is connected to the air inlet 4221.

[0105] The housing 4 is the outer shell of the garment processing equipment 100, which serves to protect the internal components, support the structure, and shape the overall appearance, providing a closed space for the equipment.

[0106] In some embodiments, the housing 4 and the back plate 12 of the cylindrical assembly 1 are connected by a bayonet.

[0107] The main body 41 is the main part of the box 4, which constitutes the basic shape and space of the box 4 and undertakes the main support and containment functions.

[0108] The rear cover assembly 42 is installed at the rear of the housing body 41 and is typically used to close the rear opening of the housing body 41, while also providing assistance for the installation and functional implementation of other components.

[0109] Mounting hole 411 is a hole made on the housing body 41 for mounting the rear cover assembly 42, so that the rear cover assembly 42 can be securely connected to the housing body 41, and may also provide a channel for the connection or function of other components.

[0110] The clearance opening 4211 is an opening provided on the rear cover assembly 42. The clearance opening 4211 is connected to the air outlet 312, so that the gas discharged from the air outlet 312 can be smoothly discharged to the outside of the clothing handling equipment 100.

[0111] The air inlet 4221 is an opening on the rear cover assembly 42 used to introduce external air and provide a source of fresh air for air circulation inside the equipment.

[0112] The air intake device 13 is part of the cylindrical assembly 1 and is connected to the air inlet 4221. It is responsible for guiding the air entering from the air inlet 4221 to the clothing processing chamber 11 of the equipment and regulating the air flow rate and velocity.

[0113] In some embodiments, the air inlet 4221 and the air intake device 13 are spaced apart. The interior of the housing 4 is a sealed space, and both the air intake device 13 and the air inlet are connected to this sealed space. When the device is started, the exhaust duct 211 begins to exhaust air, and the clothing processing chamber 11 inside the cylindrical assembly 1 will generate negative pressure due to the exhaust. This negative pressure is transmitted to the interior of the housing 4 through the air intake device 13. Thus, when the exhaust duct 211 starts to exhaust air, the sealed space inside the housing 4 will also generate negative pressure. Under the action of air pressure, external gas first enters the interior of the housing 4 through the air inlet, and then enters the clothing processing chamber 11 through the air intake device 13, thereby forming a complete airflow circulation path. Exemplarily, the air intake device 13 is located away from the ventilation hole in the cylindrical assembly 1. After the gas enters from the air intake device 13, it passes through the clothing processing chamber 11 and is then discharged from the ventilation hole by the exhaust assembly 2, thereby increasing the flow path length of the gas in the clothing processing chamber 11 and improving the ventilation efficiency of the clothing processing chamber 11. For example, the ventilation hole and the air intake device 13 are arranged diagonally opposite each other. For instance, the ventilation hole is located at the upper center of the back plate 12, and the air intake device 13 is located at the lower right of the tube assembly 1, which further increases the flow path length of the gas in the clothing processing chamber 11.

[0114] The air intake device 13 can take many forms, such as an adjustable air intake valve, which can be used to adjust the airflow into the equipment by controlling the opening of the valve, so as to adapt to different clothing processing modes and environmental conditions.

[0115] The configuration of the air inlet 4221, air intake device 13, air outlet 312, and clearance opening 4211 creates a complete and rational air circulation path. During equipment operation, especially in drying mode, fresh air can smoothly enter the equipment through the air inlet 4221 and air intake device 13 to dry the clothes. After drying, the humid air can be promptly discharged through the air outlet 312 and clearance opening 4211. This efficient air circulation significantly improves clothing processing efficiency, shortens drying time, and ensures uniformity of clothing processing results. The rear cover assembly 42 and its installation method with the main body 41 make maintenance and cleaning of the equipment more convenient. The rear cover assembly 42 can be disassembled as an independent component, facilitating operator inspection, repair, and cleaning of the internal components.

[0116] In some embodiments, please refer to Figures 1 to 4 The rear cover assembly 42 includes a rear cover 421 and an air inlet decorative ring 422, which is snapped onto the rear cover 421 around its circumference. The rear cover 421 is provided with an clearance opening 4211, and the air inlet decorative ring 422 is provided with an air inlet 4221.

[0117] The air intake decorative ring 422, as part of the rear cover assembly 42, surrounds the circumference of the rear cover 421. It has a dual function: on the one hand, it is closely related to the air intake 4221 in terms of function and deeply participates in the air intake process of the equipment; on the other hand, it plays a decorative role in terms of appearance, significantly improving the overall aesthetics of the rear of the equipment.

[0118] The rear cover plate 421 is the core part of the rear cover plate assembly 42. It is generally plate-shaped and can be made of materials such as metal or plastic. The rear cover plate 421 covers the rear opening of the housing body 41 and is a key component in constructing the enclosed space of the equipment. It also provides a mounting base for other components such as the air inlet decorative ring 422. The rear cover plate 421 has a clearance opening 4211 to allow the air outlet end 312 of the silencer 3 to pass. The air guide section 31 is sealed to the rear cover plate 421, for example, by connecting it with foam. Specifically, the end face of the air guide section 31 forming the air outlet end 312 near the back plate 12 is connected to the side of the rear cover plate 421 forming the clearance opening 4211 near the air guide section 31, and the outer peripheral wall of the end of the air guide section 31 forming the air outlet end 312 is connected to the inner peripheral wall of the clearance opening 4211. For example, a chamfer is provided at the end of the second connecting section 315 to adapt to the shape of the rear cover plate 421, so that the air outlet 312 and the clearance opening 4211 of the rear cover plate 421 can fit better, optimize the air flow path, and reduce airflow obstruction.

[0119] The air inlet decorative ring 422 is installed around the rear cover plate 421 using a snap-fit ​​method, which greatly facilitates installation and maintenance. During equipment production and assembly, the snap-fit ​​operation is simple and quick, effectively improving production efficiency. Furthermore, the rationally designed clearance opening 4211 and air inlet 4221, and their coordinated operation, optimize airflow within the equipment, enhancing its operational performance.
