Description

Technical Field

[0001] The present disclosure relates to the technical field of air conditioning, and particularly to an air duct assembly and an air conditioner. Background Art

[0002] To meet diverse air treatment requirements, such as humidification functions, multiple air ducts are usually provided to enable the coordinated operation of different functional modules. In related technologies, there is room for improvement in the air duct layout of multi-air duct air conditioners. The air duct systems of some solutions have problems of complex structure and low space utilization rate, which is not conducive to the optimization of the internal space of the air conditioner and has a high cost. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the present disclosure provides an air duct assembly and an air conditioner.

[0004] According to a first aspect of an embodiment of the present disclosure, an air duct assembly is provided. The air duct assembly is provided with an air outlet. The air duct assembly includes a main air duct and a secondary air duct. A humidification module is provided in the secondary air duct. Among them, the inlets of the main air duct and the secondary air duct are connected, and the outlets of the main air duct and the secondary air duct are both connected to the air outlet.

[0005] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: The air duct assembly provided by the present disclosure includes a main air duct and a secondary air duct. Among them, the inlets of the main air duct and the secondary air duct are connected, and the outlets of the main air duct and the secondary air duct are both connected to the same air outlet, forming a compact and efficient air duct system. Among them, the main air duct and the secondary air duct share the same air flow source and share one air outlet, reducing the number and layout complexity of the air duct outlets, making more reasonable use of the internal space of the air conditioner, providing support for the miniaturization design of the device, and enabling the humid air and the air flow in the main air duct to be fully mixed and discharged at the same air outlet, making the humidity of the conveyed air flow more uniform and stable.

[0006] In some possible implementation manners, a damper mechanism is provided at the inlet of the secondary air duct. The damper mechanism has an open position and a closed position. Among them: in the open position, the main air duct and the secondary air duct are connected, and the main air duct can divert part of the air flow into the secondary air duct; in the closed position, the air flow only enters the main air duct. The damper mechanism is integrated at the connection of the inlets of the main and secondary air ducts, and there is no need to additionally set up a complex air flow reversing structure, further simplifying the overall structure. When humidification is required, the secondary air duct can be opened to enable the humidification module, and the humid air and the air flow in the main air duct are fully mixed and discharged at the same air outlet, making the humidity of the conveyed air flow more uniform and stable; when humidification is not required, the secondary air duct is closed and only the main air duct is used for air supply. This not only simplifies the complexity of the traditional multi-air duct structure but also improves the user experience and the stability of air flow control.

[0007] In some possible embodiments, the humidification module is disposed at the top and / or bottom of the air duct assembly. Thus, it can be flexibly arranged according to the design space and the position of the air outlet.

[0008] In some possible embodiments, the humidification module includes a water tank and a wet film, and at least a part of the wet film is immersed below the water surface of the water tank. Wherein, a humidification channel is formed between the upper cover plate of the water tank and the auxiliary air duct. By using the humidification channel formed between the upper cover plate of the water tank and the auxiliary air duct, it can play a role in guiding the air flow directionally, improving the stability of the air flow and the uniformity of the humidity distribution.

[0009] In some possible embodiments, the wet film is disposed at the air outlet, and the bottom of the wet film is immersed below the water surface of the water tank, and the top of the wet film extends into the humidification channel. This enables the air flow in the auxiliary air duct to pass through the wet film to carry water vapor, improving the humidification efficiency.

[0010] In some possible embodiments, the humidification module further includes a front panel, and the front panel is disposed on the side of the water tank facing the external space of the air duct assembly. Wherein, the front panel is provided with a grid corresponding to the position of the humidification channel. The front panel and the water tank can adopt a split structure, which is convenient for mold release, and the front panel can be selected as an appearance part with a different color and surface treatment process from the water tank.

[0011] In some possible embodiments, the upper cover plate of the water tank is formed with a receiving cavity for receiving the wet film. The wet film includes a wet film body and a wet film support for carrying the wet film body, and the wet film support is detachably installed in the receiving cavity. The receiving cavity formed on the upper cover plate of the water tank is detachably matched with the wet film support, making the installation and disassembly process of the wet film simple and fast, and facilitating the user to regularly clean, replace or maintain the wet film body.

[0012] In some possible embodiments, the humidification module is slidably disposed in the auxiliary air duct. Thereby, it is possible to conveniently fill water into the water tank and replace and maintain the wet film.

[0013] In some possible embodiments, first sliding guiding structures are disposed on both side portions of the humidification module, and second sliding guiding structures are disposed on two opposite inner side walls of the auxiliary air duct. The first sliding guiding structures and the second sliding guiding structures are slidably matched to enable the humidification module to slide along a preset track. By providing the sliding guiding structures, while providing sliding guidance for the humidification module, the stability during the sliding process can also be improved.

[0014] In some possible embodiments, the humidification module is provided with first engaging structures on both sides, and the two opposing inner sidewalls of the auxiliary air duct are provided with second engaging structures that engage with the first engaging structures. This helps prevent the humidification module from shifting or falling due to tilting or bumping during transportation, ensures installation stability, and ensures ease of disassembly for maintenance while ensuring safe transportation.

[0015] In some possible embodiments, the air duct assembly includes a split front cover and a split rear cover, the air outlet is provided on the front cover, and the front cover and / or the rear cover are further provided with a partition, wherein the front cover includes a first inner wall surface, the main air duct is formed between the partition and the first inner wall surface, and the rear cover includes a second inner wall surface, the secondary air duct is formed between the partition and the second inner wall surface. In this way, the number of components to be installed can be reduced, and assembly efficiency can be improved. In addition, the entire air duct system and the air duct assembly are structurally integrated, and the overall rigidity of the air duct assembly can resist the airflow load in a high-speed wind environment, reducing noise and structural loss caused by component vibration or loosening, thereby improving the stability and durability of the air duct system.

[0016] In some possible embodiments, one end of the partition extends to the air outlet, and the other end is a cantilevered end, with the cantilevered end and the second inner wall forming the entrance to the secondary air duct. The flexible extension of the cantilevered end of the partition allows for slight elastic deformation under the impact of airflow, thereby buffering pressure fluctuations between the primary and secondary air ducts and reducing turbulent noise.

[0017] In some possible embodiments, the second inner wall surface includes a curved guide surface that is concave toward a side facing away from the partition. The curved surface's guiding effect allows the airflow to flow smoothly along a predetermined path, effectively reducing airflow collisions or turbulence, and improving the uniformity of airflow distribution within the secondary air duct.

[0018] In some possible embodiments, a damper mechanism is provided at the entrance of the auxiliary air duct. The damper mechanism includes a damper plate and a damper drive motor for driving the damper plate to rotate. A stopper is provided at the swinging end of the damper plate. The stopper is configured to seal against the cantilever end of the partition when closing the auxiliary air duct. The cooperation between the stopper and the partition can both limit the movement of the damper plate and seal the air duct.

[0019] In some possible embodiments, a wind guiding component is disposed at a position corresponding to the main air duct of the air outlet. The wind guiding component includes a plurality of wind guiding vanes and a vane driving motor for driving the wind guiding vanes to rotate to change the air flow direction. An installation platform for installing the vane driving motor is disposed at the top of the air outlet. The installation platform and the partition portion are spaced apart to form a space for accommodating the wind guiding vanes. Wherein, the installation platform and the partition portion are respectively provided with shaft holes through which the vane shafts of the wind guiding vanes pass. By cooperatively arranging the shaft holes on the installation platform and the partition portion, the partition portion can be used as an installation support structure for the wind guiding vanes, eliminating the need for additional independent installation brackets, reducing the number of components and assembly processes, and simplifying the installation process of the wind guiding component.

[0020] In some possible embodiments, a plurality of ventilation holes are provided on the wind guiding vanes. By providing a plurality of ventilation holes on the wind guiding vanes, the concentrated air flow can be dispersed into multiple fine air flows through the shunting and turbulence effects, reducing the air outlet speed and weakening the feeling of direct cold air blowing, thereby achieving the gentle wind effect.

[0021] In some possible embodiments, the internal space of the air duct assembly forms the main air duct. The auxiliary air duct includes a ventilation duct. The inlet of the ventilation duct is communicated with the main air duct, and the outlet of the ventilation duct is communicated to the air outlet. The auxiliary air duct is constructed by using an independent ventilation duct, realizing the modular separation design of the main and auxiliary air ducts. This not only avoids the complex design of the air duct assembly but also can adapt to different installation requirements through the flexible arrangement of the ventilation duct.

[0022] According to a second aspect of the embodiments of the present disclosure, an air conditioner is provided, including the air duct assembly of any one of the above.

[0023] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed description of the specific implementation

[0035] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] It should be noted that all actions of obtaining signals, information, or data in this disclosure are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0037] An exemplary embodiment of the present disclosure provides an air duct assembly 1. The air duct assembly 1 is optionally applicable to air conditioners, including floor-standing air conditioners, wall-mounted air conditioners, fresh air units, and air purification equipment, etc. The fresh air unit includes an outdoor circulation type, an indoor circulation type, or an indoor and outdoor double circulation type fresh air unit, and the present disclosure does not limit this.

[0038] As Figures 1 to 9 shown, the air duct assembly provided by the present disclosure is provided with an air outlet 11. Among them, the air duct assembly 1 includes a main air duct 12 and a secondary air duct 13. A humidification module 3 is arranged in the secondary air duct 13. Among them, the inlets of the main air duct 12 and the secondary air duct 13 are connected, and the outlets of the main air duct 12 and the secondary air duct 13 are both connected to the air outlet 11.

[0039] A fan is installed on the air duct assembly 1. The fan can be, for example, an axial flow fan, including a unidirectional or bidirectional axial flow fan, and one or more fans can be provided according to actual needs. Taking an air conditioner with refrigeration and heating functions as an example, when the fan works, it sucks in air from the outside. The air contacts the evaporator under the drive of the fan and cools down or heats up, and then is discharged into the room from the air outlet 11.

[0040] The inlets of the main air duct 12 and the secondary air duct 13 are connected, and the outlets of the main air duct 12 and the secondary air duct 13 are both connected to the air outlet 11. That is to say, the main air duct 12 and the secondary air duct 13 share the same air flow source and can be discharged from the same air outlet 11. A humidification module 3 is arranged in the secondary air duct 13. The air flow can enter the secondary air duct 13, then pass through the humidification module 3 and carry water vapor and be blown out from the air outlet 11 to achieve the humidification function. Among them, Figure 1 The solid arrows show the flow direction of the air flow in the main air duct 12, and the dashed arrows show the flow direction of the air flow in the secondary air duct 13.

[0041] For example, in the prior art, humidification is usually achieved by introducing fresh air from the outside, that is, the humidification module 3 is arranged at the outlet of the fresh air module. This method results in the inability to provide the humidification function in non-fresh air modes. However, through the air conditioner provided by the present disclosure, the humidification function can be achieved even in non-fresh air modes.

[0042] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects: The air duct assembly 1 provided by the present disclosure includes a main air duct 12 and a secondary air duct 13. The inlets of the main air duct 12 and the secondary air duct 13 are connected, and the outlets of the main air duct 12 and the secondary air duct 13 are both connected to the same air outlet, forming a compact and efficient air duct system. Among them, the main air duct 12 and the secondary air duct 13 share the same air flow source and share one air outlet 11, reducing the number of air duct outlets and the layout complexity, making the internal space of the air conditioner more reasonably utilized, preventing the space waste problem caused by the scattered structure of traditional multi-air ducts, providing support for the miniaturization design of the equipment, and enabling the humid air and the air flow in the main air duct 12 to be fully mixed and discharged at the same air outlet, making the humidity of the conveyed air flow more uniform and stable. It is worth noting that by using the air duct assembly provided by the present disclosure, various humidification modes such as heating and humidifying, cooling and humidifying, or air supply and humidifying can be achieved.

[0043] In some possible implementation manners, reference may be made simultaneously to Figure 2 and Figure 3 . A damper mechanism 4 is provided at the inlet of the secondary air duct 13, and the damper mechanism 4 has an open position and a closed position. Among them, Figure 2 is shown as the damper mechanism 4 being in the open position. In the open position, the main air duct 12 and the secondary air duct 13 are connected, and the main air duct 12 can divert part of the air flow into the secondary air duct 13; Figure 3 is shown as the damper mechanism 4 being in the closed position. In the closed position, the air flow only enters the main air duct 12. That is, when the damper mechanism 4 is in the open position, both the main air duct 12 and the secondary air duct 13 are used for air outlet. When humidification is required, the secondary air duct 13 is opened, and the humid air and the air flow in the main air duct 12 are fully mixed and discharged at the same air outlet 11, and the humidity of the conveyed air flow is more uniform and stable; when humidification is not required, the secondary air duct 13 can be closed, and only the main air duct 12 is used for independent air supply. Thus, it not only simplifies the complexity of the traditional multi-air duct structure but also improves the user experience and the stability of air flow control. In addition, by adjusting the opening degree of the secondary air duct 13, the air volume entering the secondary air duct 13 can also be adjusted, thereby adjusting the humidification efficiency. And when the damper mechanism 4 is in the closed position, no air flow enters the secondary air duct 13 at this time, thus closing the humidification function.

[0044] The humidifying module 3 can be arranged at the top and / or bottom of the air duct assembly 1, so that it can be flexibly arranged according to the design space of the air duct assembly 1 and the position of the air outlet 11. For example, the humidifying module 3 can be arranged at the bottom of the air duct assembly 1. Considering that the humidifying module 3 stores water, arranging the humidifying module 3 at the bottom of the air duct assembly 1 can prevent water from leaking onto the electrical components inside the air duct assembly 1, thereby improving the safety protection performance of the air conditioner. Correspondingly, the air outlet 11 can also be arranged at the bottom of the air duct assembly 1, which is beneficial to shortening the conveying path of the humidified gas and improving the humidifying efficiency. In other embodiments, the humidifying module 3 can also be arranged at the top of the air duct assembly 1, or humidifying modules 3 are arranged at both the top and the bottom, which will not be elaborated here.

[0045] In some possible embodiments, as Figure 8 shown, the humidifying module 3 includes a water tank 31 and a wet film 32, and at least a part of the wet film 32 is immersed below the water surface of the water tank 31. Referring to Figure 1 simultaneously, a humidifying channel 131 is formed between the upper cover plate of the water tank 31 and the auxiliary air duct 13. The wet film 32 can absorb the water in the water tank 31 and evaporate it into the humidifying channel 131. The air flow entering the auxiliary air duct 13 can carry the water vapor evaporated into the humidifying channel 131, or the air flow in the auxiliary air duct 13 directly passes through the wet film 32 to carry the water vapor, and then is discharged from the air outlet 11. This fogless humidifying method has a simpler structure, does not generate noise, and has a lower maintenance cost compared with the method of setting a spraying device. By using the humidifying channel 131 formed between the upper cover plate of the water tank 31 and the auxiliary air duct 13, the function of guiding the air flow directionally can be achieved, thereby improving the stability of the air flow and the uniformity of the humidity distribution.

[0046] Optionally, the wet film 32 is arranged at the air outlet 11, and the bottom of the wet film 32 is immersed below the water surface of the water tank 31, and the top of the wet film 32 extends into the humidifying channel 131. This enables the air flow in the auxiliary air duct 13 to pass through the wet film 32 to carry the water vapor. Compared with carrying the water vapor evaporated into the humidifying channel 131, this way of directly passing through the wet film 32 can carry more water vapor and has a higher humidifying efficiency.

[0047] In some possible embodiments, as Figures 7 to 9As shown, the humidification module 3 further includes a front panel 33, which is arranged on the side of the water tank 31 facing the external space of the air duct assembly 1. Among them, a grid 331 is arranged on the front panel 33 corresponding to the position of the humidification channel 131 to facilitate the discharge of air flow. The front panel 33 and the water tank 31 can adopt a split structure, which is convenient for mold release, and the front panel 33 can be used as an appearance part, which is also convenient for selecting different colors and surface treatment processes from the water tank 31. A water tank buckle 332 and a screw post 334 can be arranged on the side of the front panel 33 facing the water tank 31. Among them, the water tank buckle 332 can be clamped and matched with the water tank 31 and play a role of pre-fixing, and the screw post 334 is used to screw the front panel 33 and the water tank 31 to further improve the reliability of their connection. In the embodiment where the humidification module mentioned later is slidably arranged in the auxiliary air duct 13, in order to facilitate the sliding operation, a handle part 333 can also be arranged on the front panel 33.

[0048] In some possible implementation manners, such as Figure 5 As shown, a receiving cavity 311 for receiving the wet film 32 is formed on the upper cover plate of the water tank 31. The wet film 32 includes a wet film body 321 and a wet film bracket 322 for carrying the wet film body 321, and the wet film bracket 322 is detachably installed in the receiving cavity 311. The detachable cooperation between the receiving cavity 311 formed on the upper cover plate of the water tank 31 and the wet film bracket 322 makes the installation and disassembly process of the wet film 32 simple and fast, which is convenient for users to regularly clean, replace or maintain the wet film body 321, avoid the growth of bacteria caused by the long-term use of the wet film 32, and the receiving cavity 311 can also play a role of installation guidance.

[0049] The humidification module 3 can be arranged in the auxiliary air duct 13 in a slidable manner, so that it can be convenient to inject water into the water tank 31 and replace and maintain the wet film 32. In some possible implementation manners, such as Figure 5 and Figure 8 As shown, first sliding guiding structures 313 are arranged on both sides of the humidification module 3, and second sliding guiding structures 112 are arranged on two opposite inner side walls of the auxiliary air duct 13. The first sliding guiding structures 313 and the second sliding guiding structures 112 are slidably matched to enable the humidification module 3 to slide along a preset track. By arranging the sliding guiding structures, while providing sliding guidance for the humidification module 3, the stability during the sliding process can also be improved. The first sliding guiding structure 313 can be configured as ribs arranged on both sides of the humidification module 3, and the second sliding structure 112 can be a strip-shaped chute that slidably cooperates with the ribs. In addition, other similar sliding guiding structures, such as a pulley and chute cooperation structure, etc., can also be applied to the present disclosure, which will not be elaborated here.

[0050] In some possible implementation manners, such as Figure 7 and Figure 8As shown, first clamping structures 312 are provided on both side portions of the humidifying module 3, and second clamping structures 111 capable of being clamped and engaged with the first clamping structures 312 are provided on two opposite inner sidewalls of the auxiliary air duct 13. This helps to prevent the humidifying module 3 from shifting or falling off due to tilting and jolting during handling, ensuring installation stability, and taking into account the convenience of disassembly during maintenance while ensuring the safety of handling. The first clamping structure 312 can be configured as a buckle, for example, and the second clamping structure 111 can be configured as an opening. When the humidifying module 3 is assembled, the buckle extends out of the opening and is locked. When it needs to be disassembled, only need to squeeze the buckle inward so that the buckle retracts into the air duct assembly 1.

[0051] The main air duct 12 and the auxiliary air duct 13 can be constructed in various ways. In some embodiments, as Figure 5 shown, the air duct assembly 1 includes a split front cover 110 and a rear cover 120, and the air outlet 11 is provided on the front cover 110. A partition portion 14 is further provided on the front cover 110 and / or the rear cover 120, that is, the partition portion 14 can be provided on the front cover 110, or the partition portion 14 can be provided on the rear cover 120, or both the front cover 110 and the rear cover 120 are provided with partial partition portions 14 and form a complete partition portion 14 after being joined. Among them, the front cover 110 includes a first inner wall surface, and the main air duct 12 is formed between the partition portion 14 and the first inner wall surface. The rear cover 120 includes a second inner wall surface 121, and the auxiliary air duct 13 is formed between the partition portion 14 and the second inner wall surface 121. For example, the partition portion 14 is provided on the front cover 110, and the main air duct 12 is formed between the partition portion 14 and the first inner wall surface. When the front cover 110 and the rear cover 120 are buckled, the auxiliary air duct 13 is formed between the partition portion 14 and the second inner wall surface 121.

[0052] This way of forming the main air duct 12 and the auxiliary air duct 13 by means of the structure of the air duct assembly 1 itself can reduce the number of parts to be installed and improve the assembly efficiency. In addition, it makes the entire air duct system and the air duct assembly 1 achieve structural integration. In a high-speed pneumatic environment, the overall rigidity of the air duct assembly 1 can resist the air flow load, reducing noise and structural loss caused by component vibration or loosening, and improving the stability and durability of the air duct system.

[0053] Optionally, as Figure 1 shown, in some possible embodiments, the partition portion 14 can be configured such that one end extends to the air outlet 11 and the other end is a cantilever end, and an inlet of the auxiliary air duct 13 is formed between the cantilever end and the second inner wall surface 121. The cantilever end here refers to the end that is not connected to other structures inside the air duct assembly 1. Due to the flexible extension characteristic of the cantilever end of the partition portion 14, it can produce a small elastic deformation under the impact of the air flow, which can buffer the air flow pressure fluctuation between the main air duct 12 and the auxiliary air duct 13 and reduce the turbulent noise.

[0054] In addition, the second inner wall surface 121 may include a curved guide surface that is recessed toward one side away from the partition 14. The curved guide surface of the second inner wall surface 121 is recessed toward the partition 14, and can actively guide the airflow within the auxiliary air duct 13. Through the guiding effect of the curved surface, the airflow flows smoothly along a preset path, effectively reducing airflow collisions or turbulence, improving the uniformity of airflow distribution within the auxiliary air duct 13, reducing resistance and noise during airflow passage, and ensuring that the airflow acts evenly on the surface of the wet film 32, thereby improving humidification efficiency and stability, and taking into account both aerodynamic performance and quietness requirements.

[0055] In some possible embodiments, a damper mechanism 4 is provided at the entrance of the auxiliary air duct 13. The damper mechanism 4 includes a damper plate 42 and a damper drive motor 41 for driving the damper plate 42 to rotate. This type of damper mechanism 4 has a simple structure and reliable driving. Figure 4 As shown, the swinging end of the damper plate 42 is provided with a stopper 421, which is used to seal against the cantilever end of the partition 14 when closing the auxiliary air duct 13. In other words, the cooperation between the stopper 421 and the partition 14 can not only limit the movement of the damper plate 42, but also play the role of sealing the air duct.

[0056] In other possible implementations, such as Figure 5 and Figure 6 As shown, the air outlet 11 is provided with an air guide assembly 5 at a position corresponding to the main air duct 12. The air guide assembly 5 includes a plurality of air guide blades 52 and a blade drive motor 51 for driving the air guide blades 52 to rotate to change the direction of the airflow. The top of the air outlet 11 is provided with a mounting platform 113 for mounting the blade drive motor 51. The mounting platform 113 and the partition 14 are spaced apart to form a space for accommodating the air guide blades 52. The mounting platform 113 and the partition 14 are respectively provided with an axial hole 141 for the blade shaft of the air guide blade 52 to pass through. By coordinating the axial hole 141 on the mounting platform 113 and the partition 14, the partition 14 can be used as a mounting support structure for the air guide blade 52, eliminating the need for an additional independent mounting bracket, reducing the number of parts and assembly steps, and simplifying the installation process of the air guide assembly 5.

[0057] Optionally, a plurality of ventilation holes 521 are provided on the air guide blade 52. By providing a plurality of ventilation holes 521 on the air guide blade 52, the concentrated airflow can be dispersed into multiple small airflows through diversion and turbulence, thereby reducing the air outlet speed and weakening the feeling of direct cold wind, thereby achieving a soft wind effect.

[0058] In addition to the above-described embodiment of using the structure of the air duct assembly itself to form the main air duct 12 and the auxiliary air duct 13, in some other possible embodiments, such as Figure 10As shown, the internal space of the air duct assembly 1 forms the main air duct 12. The auxiliary air duct 13 includes a ventilation duct 130. The inlet of the ventilation duct 130 communicates with the main air duct 12, and the outlet of the ventilation duct 130 communicates with the air outlet 11. Among them, the main air duct 12 is formed by means of the internal space of the air duct assembly 1, which can ensure the efficient air flow transportation of the main air duct 12. At the same time, the auxiliary air duct 13 is constructed by using an independent ventilation duct, realizing the modular separation design of the main and auxiliary air ducts. This not only avoids the complex design of the air duct assembly but also can adapt to different installation requirements through the flexible arrangement of the ventilation duct 130. Its damper mechanism 4 can be a valve, for example.

[0059] In the above detailed description, reference is made to the accompanying drawings, in which specific aspects in which the present disclosure can be practiced are shown by way of illustration. In this regard, terms indicating directions or expressing positional relationships such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. can be used with reference to the orientation of the described figures. Since the components of the described device can be positioned in a plurality of different orientations, the directional terms can be used for illustrative purposes and are not restrictive. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of the present disclosure. Therefore, the following detailed description should not be taken in a limiting sense.

[0060] It should be understood that unless otherwise specifically stated, the features of some embodiments of the various aspects of the present disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of any two or more of them; similarly, "at least one of..." includes any one of the related listed items and any combination of any two or more of them.

[0061] It should be understood that unless otherwise clearly defined and limited, the terms "engage", "attach", "mount", "connect", "link", "fix", etc. used in the embodiments of the present disclosure should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or communicable with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present context can be understood according to specific circumstances.

[0062] In addition, the term "above" as used herein with respect to a component, element, or layer of material formed "above" or located "above" a surface can be used to mean that the component, element, or layer of material is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are disposed between the surface and the component, element, or layer of material. However, the term "above" as used herein with respect to a component, element, or layer of material formed "above" or located "above" a surface can also optionally have a specific meaning: the component, element, or layer of material is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, e.g., in direct contact with the surface.

[0063] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or sections, these components, elements, regions, layers, or sections are not limited to these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or section from another. Thus, the first component, element, region, layer, or section referred to in the examples described herein could also be termed the second component, element, region, layer, or section without departing from the teachings of the examples. Additionally, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In the description herein, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically and explicitly defined.

[0064] It should be understood that spatial relative terms, such as "above", "upper", "below", and "lower", are used herein to describe the relationship of one element shown in the figures to another element. In addition to the orientation depicted in the figures, such spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to that other element. Thus, the term "above" encompasses both the above and below orientations depending on the spatial orientation of the device. The device may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0065] In addition, as used herein, the word "exemplary" is used to mean serving as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous over other aspects or designs. Rather, the word exemplary is intended to present concepts in a concrete fashion. As used herein, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from the context, "X applies A or B" is intended to mean any of the natural inclusive permutations. That is, if X applies A; X applies B; or X applies both A and B, then "X applies A or B" is satisfied under any of the foregoing instances. Additionally, unless specified otherwise or clear from the context that it refers to the singular form, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more".

[0066] Likewise, although the present disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding this specification and the drawings. The present disclosure includes all such modifications and variations and is limited only by the scope of the claims. Specifically with respect to the various functions performed by the components (e.g., elements, resources, etc.) described above, unless otherwise indicated, the terms used to describe such components are intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if not structurally equivalent to the disclosed structure. Additionally, although a particular feature of the present disclosure may have been disclosed with respect to only one of several implementations, such a feature may, as may be desired and advantageous for any given or particular application, be combined with one or more other features of other implementations. Further, with respect to the use of "comprises", "comprising", "has", "having", "includes", or variants thereof in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term "including".

[0067] Other embodiments of the present disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include known in the art or conventional technical means not disclosed in the present disclosure. The specification and examples are to be considered exemplary only, and the true scope and spirit of the present disclosure are pointed out by the appended claims.

[0068] It should be understood that the present disclosure is not limited to the exact structures described above and shown in the drawings, and various modifications and changes may be made without departing from its scope. The scope of the present disclosure is limited only by the appended claims.
