Description

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more particularly to an air duct assembly and an air conditioner. Background Technology

[0002] To meet diverse air handling needs, such as humidification, multiple air ducts are typically used to enable the coordinated operation of different functional modules. In related technologies, multi-duct air conditioners have room for improvement in duct layout. Some solutions suffer from complex structures and low space utilization, hindering internal space optimization and resulting in higher costs. Summary of the Invention

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

[0004] According to a first aspect of the present disclosure, an air duct assembly is provided, the air duct assembly being provided with an air outlet, the air duct assembly including a main air duct and a secondary air duct, wherein a humidification module is provided in the secondary air duct, wherein 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 solutions provided by the embodiments of this disclosure can include the following beneficial effects: The air duct assembly provided by this disclosure includes a main air duct and a secondary air duct, wherein 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. The main air duct and the secondary air duct share the same airflow source and share a single air outlet, reducing the number of air duct outlets and layout complexity, allowing for more rational use of the internal space of the air conditioner, supporting the miniaturization design of the equipment, and ensuring that humidified air and the airflow of the main air duct are fully mixed and discharged at the same air outlet, resulting in more uniform and stable humidity of the delivered airflow.

[0006] In some possible implementations, a damper mechanism is provided at the inlet of the secondary air duct. This damper mechanism has an open position and a closed position. In the open position, the main air duct and the secondary air duct are connected, allowing the main air duct to divert some airflow into the secondary air duct. In the closed position, airflow only enters the main air duct. The damper mechanism is integrated into the connection point between the main and secondary air duct inlets, eliminating the need for a complex additional airflow reversing structure and further simplifying the overall design. When humidification is required, opening the secondary air duct activates the humidification module, allowing humidified air to mix thoroughly with the main air duct airflow at the same outlet, resulting in more uniform and stable humidity distribution. When humidification is not required, closing the secondary air duct allows air to be supplied only through the main air duct. This simplifies the complexity of traditional multi-duct structures and improves user experience and airflow control stability.

[0007] In some possible implementations, the humidification module is disposed at the top and / or bottom of the air duct assembly. This allows for flexible configuration based on available space and the location of the air outlet.

[0008] In some possible implementations, the humidification module includes a water tank and a wet film, the wet film being at least partially submerged below the water surface in the water tank, wherein a humidification channel is formed between the upper cover of the water tank and the secondary air duct. The humidification channel formed between the upper cover of the water tank and the secondary air duct can guide airflow in a directional manner, improving the stability of airflow and the uniformity of humidity distribution.

[0009] In some possible implementations, the wet membrane is positioned at the air outlet, with its bottom submerged below the water surface in the water tank and its top extending into the humidification channel. This allows airflow within the secondary duct to pass through the wet membrane to carry moisture, thereby improving humidification efficiency.

[0010] In some possible implementations, the humidification module further includes a front panel disposed on the side of the water tank facing the external space of the air duct assembly, wherein the front panel has a grid corresponding to the humidification channel. The front panel can be separately constructed from the water tank for easy demolding, and the front panel can be selected as an exterior component with a different color and surface treatment than the water tank.

[0011] In some possible implementations, the top cover of the water tank forms a receiving cavity for accommodating the wet membrane. The wet membrane includes a wet membrane body and a wet membrane support for supporting the wet membrane body, and the wet membrane support is detachably installed within the receiving cavity. The detachable engagement between the receiving cavity formed by the top cover of the water tank and the wet membrane support makes the installation and removal of the wet membrane simple and quick, facilitating users to regularly clean, replace, or maintain the wet membrane body.

[0012] In some possible implementations, the humidification module is retractable within the secondary air duct. This allows for convenient water filling of the water tank and replacement and maintenance of the wet membrane.

[0013] In some possible implementations, the humidification module has a first sliding guide structure on both sides, and the two opposite inner sidewalls of the secondary air duct have a second sliding guide structure. The first and second sliding guide structures are slidably engaged to allow the humidification module to slide along a preset trajectory. By providing sliding guide structures, the stability during the sliding process can be improved while providing sliding guidance for the humidification module.

[0014] In some possible implementations, the humidification module has a first snap-fit ​​structure on both sides, and the two opposite inner sidewalls of the secondary air duct have a second snap-fit ​​structure that can engage with the first snap-fit ​​structure. This helps to prevent the humidification module from shifting or falling off due to tilting or bumping during transportation, ensuring installation stability, and balancing transportation safety with ease of disassembly during maintenance.

[0015] In some possible implementations, the duct assembly includes a split front cover and a rear cover, with the air outlet disposed on the front cover. The front cover and / or the rear cover also have a partition. The front cover includes a second inner wall surface, and the main duct is formed between the partition and the second inner wall surface. The rear cover includes a first inner wall surface, and the secondary duct is formed between the partition and the first inner wall surface. This reduces the number of components to be installed, improving assembly efficiency. Furthermore, it integrates the entire duct system with the duct assembly, allowing the duct assembly to rigidly resist airflow loads in high-speed wind environments, reducing noise and structural damage caused by component vibration or loosening, and improving the stability and durability of the duct system.

[0016] In some possible implementations, one end of the partition extends to the air outlet, and the other end is a cantilever end, with the cantilever end forming the inlet of the secondary air duct between itself and the first inner wall surface. The flexible extension characteristic of the cantilever end of the partition allows for slight elastic deformation under airflow impact, which can buffer airflow pressure fluctuations between the main and secondary air ducts and reduce turbulence noise.

[0017] In some possible implementations, the first inner wall surface includes an arc-shaped guide surface, which is recessed on the side opposite to the partition. The guiding effect of the arc-shaped surface allows the airflow to flow smoothly along a preset path, effectively reducing airflow impact or turbulence and improving the uniformity of airflow distribution within the secondary duct.

[0018] In some possible implementations, a damper mechanism is provided at the inlet of the secondary air duct. The damper mechanism includes a damper plate and a damper drive motor for driving the damper plate to rotate. A stop portion is provided at the swing end of the damper plate, which is used to seal and stop at the cantilever end of the partition when the secondary air duct is closed. Through the cooperation between the stop portion and the partition, the movement of the damper plate can be limited, and the air duct can be sealed.

[0019] In some possible implementations, an air guide assembly is provided at the air outlet corresponding to the position of the main air duct. The air guide assembly includes multiple air guide blades and a blade drive motor for driving the air guide blades to rotate and change the airflow direction. A mounting platform for mounting the blade drive motor is provided at the top of the air outlet. The mounting platform and the partition are spaced apart to form a space for accommodating the air guide blades. The mounting platform and the partition are respectively provided with shaft holes through which the blade shafts of the air guide blades pass. By providing shaft holes in the mounting platform and the partition, the partition can serve as a mounting support structure for the air guide blades, eliminating the need for additional independent mounting brackets, reducing the number of parts and assembly steps, and simplifying the installation process of the air guide assembly.

[0020] In some possible implementations, the air guide vanes are provided with multiple ventilation holes. By providing multiple ventilation holes on the air guide vanes, the concentrated airflow can be dispersed into multiple fine airflows through diversion and turbulence, reducing the airflow velocity and weakening the direct blowing sensation of cold air, thus achieving a gentle breeze effect.

[0021] In some possible implementations, the internal space of the duct assembly forms the main duct, and the secondary duct includes a ventilation pipe. The inlet of the ventilation pipe is connected to the main duct, and the outlet of the ventilation pipe is connected to the air outlet. Utilizing independent ventilation pipes to construct the secondary duct achieves a modular and separate design of the main and secondary ducts, avoiding complex duct assembly design and allowing for flexible arrangement of ventilation pipes to adapt to different installation requirements.

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

Detailed Implementation

[0036] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0037] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0038] This disclosure provides an exemplary embodiment of a duct assembly 1. The duct assembly 1 can be optionally applied to an air conditioner, which includes a cabinet air conditioner, a wall-mounted air conditioner, a fresh air unit, and an air purification device, etc. The fresh air unit includes an outdoor circulation type, an indoor circulation type, or an indoor-outdoor dual circulation type fresh air unit, and this disclosure does not limit it.

[0039] like Figures 1 to 9 As shown, the air duct assembly provided in this disclosure is provided with an air outlet 11. The air duct assembly 1 includes a main air duct 12 and a secondary air duct 13. A humidification module 3 is provided in the 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 air outlet 11.

[0040] The fan is installed on the air duct assembly 1. The fan can be, for example, an axial flow fan, including unidirectional or bidirectional axial flow fans, and one or more fans can be installed according to actual needs. Taking an air conditioner with cooling and heating functions as an example, when the fan is working, it draws in air from the outside. The airflow is cooled or heated by contacting the evaporator under the drive of the fan, and then discharged into the room from the air outlet 11.

[0041] The inlets of the main air duct 12 and the secondary air duct 13 are connected, and the outlets of both are connected to the air outlet 11. That is, the main air duct 12 and the secondary air duct 13 share the same airflow source and can be discharged from the same air outlet 11. A humidification module 3 is installed inside the secondary air duct 13. Airflow can enter the secondary air duct 13, pass through the humidification module 3, and carry water vapor before being blown out from the air outlet 11 to achieve the humidification function. Figure 1 Solid arrows indicate the direction of airflow within the main air duct 12, while dashed arrows indicate the direction of airflow within the secondary air duct 13.

[0042] For example, in existing technologies, humidification is typically achieved by introducing fresh air from outdoors, i.e., the humidification module 3 is located at the outlet of the fresh air module. This method results in the inability to provide humidification in non-fresh air mode. However, the air conditioner provided in this disclosure can achieve humidification even in non-fresh air mode.

[0043] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: The air duct assembly 1 provided by this 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. The main air duct 12 and the secondary air duct 13 share the same airflow source and share a single air outlet 11, reducing the number of air duct outlets and the complexity of the layout. This allows for more rational use of the internal space of the air conditioner, preventing the space waste problem caused by the dispersed structure of traditional multi-duct systems. This provides support for the miniaturization design of the equipment. Furthermore, the humidified air and the airflow of the main air duct 12 are fully mixed and discharged through the same air outlet, resulting in a more uniform and stable humidity of the delivered airflow. It is worth noting that the air duct assembly provided by this disclosure can realize multiple humidification modes such as heating humidification, cooling humidification, or air supply humidification.

[0044] In some possible implementations, reference may also be made to Figure 2 and Figure 3 A damper mechanism 4 is installed at the inlet of the secondary air duct 13, and the damper mechanism 4 has an open position and a closed position. Figure 2 The damper mechanism 4 is shown in the open position. In the open position, the main air duct 12 and the secondary air duct 13 are connected, allowing the main air duct 12 to divert some airflow into the secondary air duct 13. Figure 3 The diagram shows the damper mechanism 4 in the closed position, where airflow 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 needed, the secondary air duct 13 is opened, allowing humidified air to mix thoroughly with the airflow from the main air duct 12 and be discharged through the same outlet 11, resulting in more uniform and stable humidity distribution. When humidification is not needed, the secondary air duct 13 can be closed, with airflow delivered independently only through the main air duct 12. This simplifies the complexity of traditional multi-duct structures and improves user experience and airflow control stability. Furthermore, by adjusting the opening of the secondary air duct 13, the airflow entering the secondary air duct 13 can be adjusted, thereby adjusting the humidification efficiency. When the damper mechanism 4 is in the closed position, no airflow enters the secondary air duct 13, thus disabling the humidification function.

[0045] The humidifying module 3 can be located at the top and / or bottom of the air duct assembly 1, allowing for flexible placement based on 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 located at the bottom of the air duct assembly 1. Considering that the humidifying module 3 stores water, placing it at the bottom of the air duct assembly 1 prevents water from leaking onto the electrical components inside the air duct assembly 1, thereby improving the safety performance of the air conditioner. Correspondingly, the air outlet 11 can also be located at the bottom of the air duct assembly 1, which helps to shorten the delivery path of the humidifying gas and improve humidification efficiency. In other embodiments, the humidifying module 3 can also be located at the top of the air duct assembly 1, or both at the top and bottom, which will not be elaborated further.

[0046] In some possible implementations, such as Figure 8 As shown, the humidification module 3 includes a water tank 31 and a wet film 32, with the wet film 32 at least partially submerged below the water surface of the water tank 31. (See also...) Figure 1 A humidification channel 131 is formed between the upper cover of the water tank 31 and the secondary air duct 13. The wet film 32 absorbs water from the water tank 31 and evaporates it into the humidification channel 131. The airflow entering the secondary air duct 13 carries the water vapor that has evaporated into the humidification channel 131, or the airflow in the secondary air duct 13 passes directly through the wet film 32 and carries the water vapor, and then is discharged from the air outlet 11. This mist-free humidification method is simpler in structure than the method of setting a spray device, does not generate noise, and has lower maintenance costs. The humidification channel 131 formed between the upper cover of the water tank 31 and the secondary air duct 13 can guide the airflow in a directional manner, thereby improving the stability of the airflow and the uniformity of humidity distribution.

[0047] Optionally, the wet membrane 32 is positioned at the air outlet 11, with its bottom submerged below the water surface of the water tank 31, and its top extending into the humidification channel 131. This allows the airflow within the secondary air duct 13 to pass through the wet membrane 32 to carry moisture. Compared to carrying moisture that evaporates into the humidification channel 131, this method of directly passing through the wet membrane 32 carries more moisture and achieves higher humidification efficiency.

[0048] In some possible implementations, such as Figures 7 to 9As shown, the humidification module 3 also includes a front panel 33, which is disposed on the side of the water tank 31 facing the external space of the air duct assembly 1. The front panel 33 has a grid 331 positioned corresponding to the humidification channel 131 to facilitate airflow discharge. The front panel 33 can be a separate component from the water tank 31 for easy demolding, and it can also serve as an exterior part, allowing for the selection of different colors and surface treatments from the water tank 31. The side of the front panel 33 facing the water tank 31 may be provided with a water tank clip 332 and a screw post 334. The water tank clip 332 can engage with the water tank 31 for pre-fixation, and the screw post 334 is used to screw the front panel 33 to the water tank 31, further improving the reliability of the connection. In the embodiment described later, where the humidification module 3 is retractably disposed within the secondary air duct 13, the front panel 33 may also be provided with a handle 333 for easy retraction.

[0049] In some possible implementations, such as Figure 5 As shown, the upper cover of the water tank 31 forms a receiving cavity 311 for accommodating the wet membrane 32. The wet membrane 32 includes a wet membrane body 321 and a wet membrane support 322 for supporting the wet membrane body 321. The wet membrane support 322 is detachably installed in the receiving cavity 311. The receiving cavity 311 formed by the upper cover of the water tank 31 and the wet membrane support 322 are detachably matched, making the installation and removal of the wet membrane 32 simple and quick. This facilitates users to regularly clean, replace, or maintain the wet membrane body 321, preventing bacterial growth due to long-term use of the wet membrane 32. Furthermore, the receiving cavity 311 also serves as an installation guide.

[0050] The humidification module 3 can be pulled out and installed within the secondary air duct 13, allowing for convenient water filling of the water tank 31 and replacement and maintenance of the wet membrane 32. In some possible implementations, such as Figure 5 and Figure 8 As shown, the humidifying module 3 has a first sliding guide structure 313 on both sides, and a second sliding guide structure 112 on the two opposite inner sidewalls of the secondary air duct 13. The first sliding guide structure 313 and the second sliding guide structure 112 are slidably engaged to allow the humidifying module 3 to slide along a preset trajectory. By providing sliding guide structures, the stability during the sliding process can be improved while providing sliding guidance for the humidifying module 3. The first sliding guide structure 313 can be constructed as a rib on both sides of the humidifying module 3, and the second sliding structure 112 can be a strip-shaped groove that slidably engages with the rib. In addition, other similar sliding guide structures, such as pulley and groove matching structures, can also be applied in this disclosure, which will not be described in detail here.

[0051] In some possible implementations, such as Figure 7 and Figure 8As shown, the humidifying module 3 has a first snap-fit ​​structure 312 on both sides, and the two opposite inner sidewalls of the secondary air duct 13 have a second snap-fit ​​structure 111 that can snap into the first snap-fit ​​structure 312. This helps to prevent the humidifying module 3 from shifting or falling off due to tilting or bumping during transportation, ensuring installation stability, and taking into account the convenience of disassembly during maintenance while ensuring transportation safety. The first snap-fit ​​structure 312 can be constructed as a buckle, for example, and the second snap-fit ​​structure 111 can be constructed as an opening. After the humidifying module 3 is assembled, the buckle extends out from the opening and locks in place. When it needs to be removed, simply squeeze the buckle inward to retract it into the air duct assembly 1.

[0052] The main air duct 12 and the secondary air duct 13 can be constructed in various ways. In some embodiments, such as... Figure 5 As shown, the air duct assembly 1 includes a split front cover 110 and a rear cover 120, with an air outlet 11 disposed on the front cover 110. The front cover 110 and / or the rear cover 120 also have a partition 14; that is, the partition 14 can be disposed on the front cover 110, or on the rear cover 120, or both the front cover 110 and the rear cover 120 may have partial partitions 14, forming a complete partition 14 after assembly. The front cover 110 includes a second inner wall surface, and a main air duct 12 is formed between the partition 14 and the second inner wall surface. The rear cover 120 includes a first inner wall surface 121, and a secondary air duct 13 is formed between the partition 14 and the first inner wall surface 121. For example, the partition 14 is provided on the front cover 110, and the partition 14 forms a main air duct 12 between the second inner wall surface. After the front cover 110 and the rear cover 120 are fastened together, the partition 14 forms a secondary air duct 13 between the first inner wall surface 121.

[0053] This method of forming the main air duct 12 and the secondary air duct 13 by utilizing the structure of the air duct component 1 itself can reduce the number of parts to be installed and improve assembly efficiency. In addition, it enables the entire air duct system to achieve structural integration with the air duct component 1. In high-speed wind environments, the overall rigidity of the air duct component 1 can resist airflow loads, reduce noise and structural losses caused by component vibration or loosening, and improve the stability and durability of the air duct system.

[0054] Optionally, such as Figure 1 As shown, in some possible embodiments, the partition 14 can be configured such that one end extends to the air outlet 11 and the other end is a cantilever, with the cantilever forming the inlet of the secondary air duct 13 between the cantilever and the first inner wall surface 121. Here, the cantilever refers to the end that is not connected to other structures within the air duct assembly 1. Due to the flexible extension characteristics of the cantilever end of the partition 14, it can generate slight elastic deformation under airflow impact, which can buffer airflow pressure fluctuations between the main air duct 12 and the secondary air duct 13, reducing turbulence noise.

[0055] Furthermore, the first inner wall surface 121 may include an arc-shaped guide surface, which is recessed on the side facing away from the partition 14. The arc-shaped guide surface of the first inner wall surface 121 is recessed in the direction away from the partition 14, which can actively guide the airflow in the secondary air duct 13. Through the guiding effect of the arc-shaped curved surface, the airflow flows smoothly along a preset path, effectively reducing airflow impact or turbulence, improving the uniformity of airflow distribution in the secondary air duct 13, reducing airflow resistance and noise, and at the same time ensuring that the airflow acts evenly on the surface of the wet film 32, improving humidification efficiency and stability, and taking into account both aerodynamic performance and quiet operation requirements.

[0056] In some possible implementations, a damper mechanism 4 is provided at the inlet of the secondary 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 drive. For example... Figure 4 As shown, the swing end of the damper plate 42 is provided with a stop 421, which is used to seal and stop the cantilever end of the partition 14 when the secondary air duct 13 is closed. That is, through the cooperation of the stop 421 and the partition 14, the movement of the damper plate 42 can be limited, and the air duct can be sealed.

[0057] In other possible implementations, such as Figure 5 and Figure 6 As shown, an air guide assembly 5 is provided at the air outlet 11 corresponding to the position of the main air duct 12. The air guide assembly 5 includes multiple air guide blades 52 and a blade drive motor 51 for driving the air guide blades 52 to rotate and change the airflow direction. A mounting platform 113 for mounting the blade drive motor 51 is provided on the top of the air outlet 11. 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 shaft holes 141 for the blade shafts of the air guide blades 52 to pass through. By providing shaft holes 141 in cooperation between the mounting platform 113 and the partition 14, the partition 14 can be used as a mounting support structure for the air guide blades 52, eliminating the need for additional independent mounting brackets, reducing the number of parts and assembly steps, and simplifying the installation process of the air guide assembly 5.

[0058] Optionally, the air guide vane 52 is provided with multiple ventilation holes 521. By providing multiple ventilation holes 521 on the air guide vane 52, the concentrated airflow can be dispersed into multiple fine airflows through diversion and turbulence, thereby reducing the airflow speed and weakening the feeling of direct cold air blowing, achieving a gentle breeze effect.

[0059] In addition to the above-described implementation method that utilizes the structure of the air duct assembly itself to form the main air duct 12 and the secondary air duct 13, there are other possible implementation methods, such as... Figure 10As shown, the internal space of the duct assembly 1 forms the main air duct 12, and the secondary air duct 13 includes a ventilation duct 130. The inlet of the ventilation duct 130 is connected to the main air duct 12, and the outlet of the ventilation duct 130 is connected to the air outlet 11. The main air duct 12, formed within the internal space of the duct assembly 1, ensures efficient airflow. Meanwhile, the secondary air duct 13, constructed using an independent ventilation duct, achieves a modular and separate design for the main and secondary air ducts. This avoids complex duct assembly design and allows for flexible arrangement of the ventilation duct 130 to adapt to different installation requirements. The damper mechanism 4 can be, for example, a valve.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0063] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0064] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these 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 would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0066] Furthermore, the term “exemplary” is used herein 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 compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer 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.”

[0067] Similarly, although this 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 accompanying drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”

[0068] Other embodiments of this 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 this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the appended claims.

[0069] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
