Description

Technical Field

[0001] This application relates to the field of heating device technology, and more specifically, to a heating device and a cooking appliance. Background Technology

[0002] In related technologies, heating devices include a housing, a fan, and a coil structure. Both the fan and the coil structure are located within the housing. When the fan operates, it drives airflow horizontally towards the coil structure to dissipate heat. However, the housing lacks an effective airflow guiding structure. Due to the diffuse nature of the airflow and its horizontal flow towards the coil structure, the actual airflow in contact with the coil structure is relatively small. This results in slow heat exchange between the airflow and the coil structure, leading to low heat dissipation efficiency and negatively impacting the performance of the heating device. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first aspect of this application proposes a heating device.

[0005] The second aspect of this application proposes a cooking utensil.

[0006] In view of the above, the first aspect of this application proposes a heating device, comprising: a housing assembly having an air inlet and an air outlet, and a first guide plate and a support structure disposed within the housing assembly; a fan disposed within the housing assembly, the fan connecting the air inlet and the air outlet, the first guide plate being located between the support structure and the fan; and a coil structure stacked on the support structure, the support structure having a steering rib on the side facing the coil structure; wherein the fan operates to drive airflow through the first guide plate to the support structure, and is guided by the steering rib to the coil structure.

[0007] The heating device provided in this application includes a housing assembly, a fan, and a coil structure. Both the fan and the coil structure are located within the housing assembly.

[0008] The housing assembly has an air inlet and an air outlet, and the fan is connected to the air inlet and the air outlet.

[0009] The housing assembly contains a first guide vane and a support structure. The first guide vane is located between the support structure and the fan. The coil structure is stacked on the support structure, which supports and secures the coil structure. The support structure has steering ribs on the side facing the coil structure.

[0010] The fan operates by driving airflow from the environment into the housing assembly through the air inlet. Guided by the first guide plate, the airflow flows towards the support structure. Guided by the deflecting ribs, the airflow moves towards the coil structure, flowing from the bottom to the top of the coil structure, and finally exiting the heating device through the air outlet. This airflow effectively dissipates heat from the coil structure, ensuring its cooling performance. It is understood that the deflecting ribs are positioned to match the coil structure, altering the airflow path and effectively guiding the airflow to the coil structure for efficient heat dissipation.

[0011] Understandably, compared to a fan housed separately within an outer casing, where the fan is in a completely open space, the first guide vane and support structure work together to limit the airflow path, concentrating the airflow and ensuring its effective flow to the coil structure. Specifically, when the airflow reaches the deflecting ribs, the originally horizontal airflow is guided upwards towards the bottom of the coil structure. This increases the contact area between the airflow and the coil structure, ensuring effective contact between the bottom and top of the coil structure. This accelerates heat exchange between the coil structure and the airflow, improving heat dissipation efficiency.

[0012] Furthermore, the coil structure is stacked on the support structure. The support structure not only supports the coil structure but also alters the airflow path, effectively guiding the airflow to the coil structure for efficient heat dissipation. This design reuses the support structure, enriches its functionality, reduces the need for guiding materials, and enhances product performance and market competitiveness.

[0013] Understandably, the steering ribs protrude from the outer surface of the bracket, thus allowing for the movement or disassembly of the bracket structure by gripping them, providing ease of operation and improving product assembly and disassembly efficiency. In other words, the steering ribs not only change the direction of airflow but also provide a gripping function, enriching their overall functionality.

[0014] In some technical solutions, the steering ribs are optionally positioned opposite the coil structure.

[0015] In this technical solution, the cooperation structure between the steering rib and the coil structure is further defined.

[0016] The steering ribs are positioned opposite to the coil structure. Specifically, the bottom of the steering ribs is positioned opposite to the bottom of the coil structure. This allows the airflow to change its path when passing through the steering ribs, causing the airflow to flow from the bottom to the top of the coil structure and penetrate it. This increases the contact area between the airflow and the coil structure, ensuring that both the bottom and top of the coil structure can effectively contact the airflow. This accelerates the heat exchange between the coil structure and the airflow and improves heat dissipation efficiency.

[0017] In some technical solutions, the center of the coil structure is optionally located between the steering rib and the first guide vane.

[0018] In this technical solution, the cooperation structure of the coil structure, the steering rib and the first guide plate is further defined, so that the middle part of the coil structure is located between the steering rib and the first guide plate. That is, along the direction from the first guide plate to the support structure, the steering rib is located behind the middle part of the coil structure.

[0019] The main heat-generating structure of the coil is located on the periphery of the middle part of the coil. Therefore, the steering ribs are arranged behind the middle part of the coil so that the airflow can be guided upward behind the middle part of the coil to ensure the contact area and contact zone between the airflow and the coil. This can accelerate the heat exchange speed between the coil and the airflow and improve the heat dissipation efficiency.

[0020] In some technical solutions, optionally, along the direction from the first guide plate to the steering rib, the first guide plate is projected onto the end face of the steering rib facing the first guide plate, and the projection of the first guide plate is located between the two circumferential end faces of the steering rib.

[0021] In this technical solution, the cooperative structure of the first guide plate and the steering rib is further defined such that, along the direction from the first guide plate to the steering rib, the first guide plate is projected orthographically onto the end face of the steering rib facing the first guide plate, and the projection of the first guide plate is located between the two circumferential end faces of the steering rib. This further defines the flow path of the airflow from the first guide plate to the support structure.

[0022] When the airflow passes through the first guide plate, the first guide plate guides the flow path of the airflow. The airflow is gathered and flows to the turning rib of the support structure to ensure the airflow to the turning rib, and thus ensure the airflow to the coil structure through the turning rib, providing structural support for ensuring the heat dissipation effect of the coil structure.

[0023] In some technical solutions, the first guide plate can optionally be a groove-shaped structure recessed towards the fan, with a first opening at the bottom of the groove-shaped structure, and the first opening connected to the fan.

[0024] In this technical solution, the structure of the first guide plate is further defined.

[0025] The first guide vane is a recessed trough-shaped structure facing the fan. The bottom of the trough-shaped structure has a first opening, which connects to the fan. That is, the bottom of the trough-shaped structure is located between the opening of the trough-shaped structure and the fan; or, the opening of the trough-shaped structure is located between the bottom of the trough-shaped structure and the steering rib.

[0026] The fan operates to drive airflow through the first opening to the trough structure, then to the support structure under the guidance of the trough wall, and finally to the coil structure under the guidance of the steering rib.

[0027] The trough structure and the support structure work together to limit the airflow path and provide structural support to ensure the heat dissipation effect of the coil structure.

[0028] In some technical solutions, optionally, a portion of the support structure extends into the channel structure through the slot of the channel structure.

[0029] In this technical solution, the cooperation structure between the support structure and the first guide plate is further defined.

[0030] A portion of the support structure extends into the trough structure through its opening. The support structure and the first guide plate work together to effectively guide the airflow. The support structure and the first guide plate enclose a relatively continuous guiding structure, allowing the airflow to be effectively guided to the steering ribs.

[0031] In addition, the fact that part of the support structure is located inside the trough structure helps to reduce the overall size of the support structure and the first guide plate, thereby reducing the internal space occupancy of the heating device and facilitating the rational layout of other components of the heating device.

[0032] In some technical solutions, the steering rib may optionally be an arc-shaped rib that bends away from the first guide vane.

[0033] In this technical solution, the structure of the steering rib is further defined so that the steering rib is an arc-shaped rib that bends away from the first guide plate. The arc-shaped rib has a smooth curved surface. The smooth curved surface can avoid the sudden turning of the airflow, which is conducive to reducing boundary layer separation, reducing the probability of turbulence formation, reducing energy loss, and enabling the airflow to move more efficiently towards the coil structure.

[0034] Understandably, the continuous curvature of the curved ribs helps maintain laminar flow, reduces airflow pulsation, and promotes stable airflow. Simultaneously, the curved ribs can disperse the stress generated by airflow impact, reducing fatigue damage. Furthermore, by extending the service life of the ribs, they help reduce vibration and noise.

[0035] In some technical solutions, optionally, the support structure includes: a support, the support including a support body and multiple support segments, each support segment connected to the support body, the multiple support segments arranged at intervals along the circumference of the support body, and a steering rib provided on one side of the support; each support segment is provided with a connecting structure, the connecting structure including a first connecting part and a second connecting part, the first connecting part being detachably connected to the coil structure, and the second connecting part being detachably connected to the housing assembly.

[0036] In this technical solution, the support structure includes a support, which comprises a support body and multiple support segments. Any one of the multiple support segments is connected to the support body, and the multiple support segments are arranged at intervals along the circumference of the support body.

[0037] Each support section is equipped with a connecting structure, which includes a first connecting part and a second connecting part. The first connecting part is detachably connected to the coil structure; that is, when assembling the bracket structure and the coil structure, the first connecting part of the connecting structure is detachably connected to the coil structure to achieve the purpose of assembling the coil structure onto the bracket structure. Thus, the coil structure is assembled into the housing assembly of the heating device via the bracket structure, and the coil structure is equipped with an independent bracket structure. The second connecting part is detachably connected to the housing assembly; that is, when assembling the bracket structure and the housing assembly of the heating device, the second connecting part of the connecting structure is detachably connected to the housing assembly to achieve the purpose of assembling the bracket structure into the housing assembly. Compared to having the coil structure and the main board on the same bracket, this reduces the tonnage of the mold used to process the bracket, which helps to reduce mold costs. Meanwhile, since the coil structure is assembled inside the housing assembly through an independent support structure, it can be positioned relatively far away from the motherboard of the heating device. Compared to the coil structure being supported above the motherboard, it can obtain more heat dissipation airflow, which helps to reduce heat exchange between the motherboard and the coil structure, optimize the temperature rise at the coil structure and the motherboard, and enable both the coil structure and the motherboard to be effectively cooled, which helps to improve the performance of the product and extend its service life.

[0038] Furthermore, multiple support segments are arranged at intervals along the circumference of the support body. Each support segment is equipped with a connecting structure, meaning that each support segment can not only connect to the housing assembly of the heating device via the connecting structure, but also connect to the coil structure via the connecting structure. This arrangement ensures the appropriate angle and area of ​​contact between the support structure, the housing assembly, and the coil structure, guaranteeing effective support and fixation of the coil structure, and ensuring the stability and reliability of the coil structure assembled within the housing assembly. Simultaneously, the interval arrangement of the multiple support segments, meaning that a gap is formed between adjacent support segments and the support body, reduces the amount of material required for the support structure, lowers its weight, reduces its volume, and ultimately lowers its production cost.

[0039] In addition, a gap will be formed between two adjacent support sections and the support body. This reduces the area of ​​the support structure relative to the coil structure while ensuring the effectiveness and reliability of the coil structure. This allows some airflow to flow from the gap to the coil structure, which helps to increase the air volume for cooling the coil structure per unit time and further improves the heat dissipation efficiency of the coil structure.

[0040] Furthermore, the coil structure is equipped with an independent support structure, which allows for detachable connection between the coil structure and the housing assembly. Therefore, various models of coil structures and support structures can be flexibly assembled within the same housing assembly to meet specific application requirements. In other words, while maintaining the same overall dimensions of the housing assembly, a support structure matching the coil structure's dimensions can be selected. This allows for the assembly of multiple coil structures within the same housing assembly, enhancing its adaptability and improving product performance and market competitiveness.

[0041] In some technical solutions, optionally, there are multiple support structures, coil structures, and first guide vanes, with each coil structure cooperating with a support structure and a first guide vane; wherein, multiple coil structures are arranged at intervals along the circumference of the fan.

[0042] In this technical solution, the number and arrangement of the support structure, coil structure and first guide plate are further defined.

[0043] The heating device comprises multiple support structures, coil structures, and first guide plates, with each coil structure cooperating with one support structure and one first guide plate. In other words, the heating device has multiple coil structures, which increases the heating area and heating efficiency. Furthermore, this design can meet the needs of simultaneously heating multiple appliances, broadening the product's adaptability.

[0044] In some technical solutions, optionally, a second guide plate and a support structure are provided inside the housing assembly, with the second guide plate located between the support structure and the fan; the heating device also includes a main control board assembly, which is stacked on the support structure, and the main control board assembly includes a main board and a fin structure, with the fin structure located on one side of the main board; wherein, the operation of the fan also drives the airflow through the second guide plate to the main control board assembly.

[0045] In this technical solution, a second guide vane and a support structure are also provided inside the housing assembly. The second guide vane is located between the support structure and the fan.

[0046] The heating device also includes a main control board assembly, which is stacked on a support structure. The support structure serves to support and fix the main control board assembly.

[0047] The fan operates by driving airflow from the environment into the housing assembly through the air inlet. The first portion of the airflow, guided by the first guide plate, flows towards the support structure. Guided by the steering ribs, this second portion flows towards the coil structure, passing from the bottom to the top. The third portion, guided by the second guide plate, flows towards the main control board assembly. This airflow effectively dissipates heat from both the coil structure and the main control board assembly, ensuring optimal cooling performance.

[0048] Understandably, the first guide vane is located between the support structure and the fan, while the second guide vane is located between the support structure and the fan. This arrangement ensures that both the coil structure and the main control board assembly have corresponding airflow for heat dissipation. Since the coil structure and the main control board assembly are located in different flow channels, they can each dissipate heat independently, effectively guaranteeing the heat dissipation performance of both.

[0049] The main control board assembly includes a motherboard and a finned structure. The finned structure is located on one side of the motherboard. The finned structure increases the heat dissipation area of ​​the main control board assembly, which increases the contact area between the main control board assembly and the external airflow, thus improving the heat dissipation efficiency of the main control board assembly.

[0050] In some technical solutions, optionally, at least a portion of the fin structure is located between the second guide plate and the main plate.

[0051] In this technical solution, the cooperative structure of the main control board assembly and the second guide plate is further defined.

[0052] At least a portion of the fin structure is located between the second guide vane and the main plate. That is, a portion of the fin structure is located between the second guide vane and the main plate, or the entire fin structure is located between the second guide vane and the main plate.

[0053] In other words, at least a portion of the second air deflector is closer to the second air deflector than the main body.

[0054] In this way, the airflow guided by the second guide plate will first flow through the fin structure and then through the main board. This helps to increase the contact area between the fin structure and the airflow, allowing the heat at the fin structure to be effectively dissipated and ensuring the heat dissipation efficiency of the main control board assembly.

[0055] In some technical solutions, optionally, the fin structure includes a support plate and multiple fins. The support plate is connected to the main board, and the multiple fins are all connected to the side of the support plate opposite to the support structure. The multiple fins are arranged at intervals along a direction perpendicular to the fan to the main board.

[0056] In this technical solution, the composition of the fin structure is further defined.

[0057] The fin structure includes a support plate and multiple fins. The support plate is connected to the main plate, and the multiple fins are connected to the side of the support plate opposite to the support structure.

[0058] Multiple fins are arranged at intervals along a direction perpendicular to the fan to the main board. It is understood that a flow channel is formed between adjacent fins, extending in the direction of the second guide plate and the main board. The direction of the flow channel's extension matches the positions of the main board and the fan. This facilitates the dissipation of heat transferred from the main board to the fin structure, improving the heat dissipation efficiency of the main control board assembly and ensuring its temperature. This provides structural support for ensuring the performance and lifespan of the heating device.

[0059] In some technical solutions, optionally, the support plate has a clearance area, a portion of the multiple fins are located on the first side of the clearance area, and another portion of the multiple fins are located on the second side of the clearance area; the heating device also includes a mounting component that passes through the clearance area and locks into the support structure; the housing assembly is also provided with a first guide rib, which is located between the fan and the fin structure, and the first guide rib is used to guide the airflow to the first side and the second side of the clearance area.

[0060] In this technical solution, the structure of the heating device is further defined.

[0061] The support plate has a clearance area, which is used to connect with the support structure to achieve the purpose of assembling the main control board assembly and the support structure.

[0062] Specifically, the heating device also includes a mounting component that passes through a clearance area and locks into the support structure to assemble the main control board assembly onto the support structure. Understandably, the clearance area is used to allow space for the mounting component to connect the main control board assembly and the support structure.

[0063] The avoidance zone has a first side and a second side, which are the opposite sides of the avoidance zone.

[0064] Some of the multiple fins are located on the first side of the avoidance zone, while another portion of the multiple fins are located on the second side of the avoidance zone. In other words, the multiple fins do not obstruct the avoidance zone.

[0065] The housing assembly also includes a first guide rib, which is located between the fan and the fin structure. The first guide rib has the function of guiding the airflow to the first side and the second side of the avoidance zone, respectively. More specifically, it guides the airflow to the fins on the first side and the second side of the avoidance zone, preventing the airflow from passing through the avoidance zone and forcing the airflow to pass through the densely arranged multiple fins, thereby improving the heat exchange rate between the airflow and the fin structure.

[0066] In some technical solutions, optionally, there are multiple avoidance zones and multiple first guide ribs. Multiple avoidance zones are arranged at intervals along a direction perpendicular to the fan to the main board, and each avoidance zone is matched with a first guide rib.

[0067] In this technical solution, the number and arrangement of the avoidance zone and the first guide rib are further defined.

[0068] There are multiple avoidance zones and multiple first guide ribs. Each avoidance zone is paired with one first guide rib, meaning that there is one first guide rib between each avoidance zone and the fan.

[0069] This design can reduce or even prevent airflow from passing through the clearance zone, allowing airflow to be effectively guided to the densely finned area, thereby improving the heat dissipation efficiency of the finned structure.

[0070] In some technical solutions, optionally, the number of fin structures is multiple, and the multiple fin structures are arranged at intervals along a direction perpendicular to the fan to the main board; the housing assembly is also provided with at least one second guide rib, the second guide rib is located between the main control board assembly and the fan, and the gap between any two adjacent fin structures is arranged opposite to a second guide rib, the second guide rib is used to guide the flow to the two adjacent fin structures.

[0071] In this technical solution, the structure of the heating device is further defined.

[0072] There are multiple finned structures, which are spaced apart along a direction perpendicular to the fan to the main board. Due to space constraints, there are gaps between adjacent finned structures. If airflow passes through these gaps, it will waste resources and reduce the heat dissipation efficiency of the main control board.

[0073] Therefore, at least one second airflow guide rib is provided within the housing assembly, positioned between the main control board and the fan. The gap between any two adjacent fin structures is positioned opposite to one of the second airflow guide ribs. The second airflow guide rib is used to guide airflow to the two adjacent fin structures; that is, the gap between two adjacent fin structures is positioned opposite to one of the second airflow guide ribs, which acts as a barrier between the gap and the fan. The second airflow guide rib has a guiding function, directing the airflow to the two adjacent fin structures respectively. This prevents the airflow from flowing through the gap between the two adjacent fin structures, forcing the airflow to pass only through the densely arranged fins on the fin structure. This helps to improve the heat exchange rate between the airflow and the fin structure, thereby enhancing the heat dissipation efficiency of the main control board assembly.

[0074] In some technical solutions, optionally, both the first guide rib and the second guide rib include: two stiffeners, each stiffener including a first end and a second end, the first ends of the two stiffeners being connected, the second ends of the two stiffeners being far apart from each other, and the first end of the stiffener being located between the fan and the second end of the stiffener; in the first guide rib, the second end of one stiffener is opposite to the portion of the support plate located on the first side of the clearance area, and the second end of the other stiffener is opposite to the portion of the support plate located on the second side of the clearance area; in the second guide rib, the second end of one stiffener is opposite to one of the two adjacent fin structures, and the second end of the other stiffener is opposite to the other of the two adjacent fin structures.

[0075] In this technical solution, the first guide rib includes two stiffeners, each with a first end and a second end. The first ends of the two stiffeners are connected, while the second ends are spaced apart from each other. That is, the two stiffeners form a "V" shape. The first end of the stiffener is located between the fan and the second end of the stiffener.

[0076] In the first guide rib, the second end of one rib is positioned opposite the portion of the support plate located on the first side of the clearance zone, and the second end of the other rib is positioned opposite the portion of the support plate located on the second side of the clearance zone. That is, the two ribs of the first guide rib have a guiding function; one rib directs the airflow to the fins on the first side of the clearance zone, and the other rib directs the airflow to the fins on the second side of the clearance zone. This reduces or even eliminates airflow into the clearance zone and provides structural support to ensure the heat dissipation efficiency of the fin structure.

[0077] The second guide rib includes two stiffeners, each with a first end and a second end. The first ends of the two stiffeners are connected, while the second ends are spaced apart. In other words, the two stiffeners form a "V" shape. The first end of the stiffener is located between the fan and the second end of the stiffener.

[0078] In the second airflow guide rib, the second end of one rib is positioned opposite to one of the two adjacent fin structures, and the second end of the other rib is positioned opposite to the other of the two adjacent fin structures. That is, the two ribs of the second airflow guide rib have a guiding function; one rib directs the airflow to one of the two adjacent fin structures, and the other rib directs the airflow to the other of the two adjacent fin structures. This reduces or even eliminates airflow flowing into the gap between the two adjacent fin structures. It provides structural support to ensure the heat dissipation efficiency of the fin structure.

[0079] In some technical solutions, the support structure is optionally provided with a mounting part, which is detachably connected to the outermost fin among a plurality of fins, and / or the mounting part is detachably connected to the outer edge of the support plate.

[0080] In this technical solution, the cooperation structure between the support structure and the main control board assembly is further defined.

[0081] The support structure is equipped with a mounting part, which can be detachably connected to the outermost fin among the multiple fins. That is, the connection between the support structure and the fin structure is located at the outermost fin among the multiple fins. In this way, there is no clearance area between the multiple fins for installation, allowing airflow to pass through more fins, which helps to improve the heat exchange speed between the airflow and the fin structure and improve the heat dissipation efficiency of the main control board.

[0082] And / or, the mounting part is detachably connected to the outer edge of the support plate. That is, the connection between the support structure and the fin structure is located at the outer edge of the support plate. In this way, there is no clearance area between multiple fins for installation, allowing airflow to pass through more fins, which helps to improve the heat exchange speed between the airflow and the fin structure and improve the heat dissipation efficiency of the main control board assembly.

[0083] In some technical solutions, optionally, both the first guide plate and the second guide plate are connected to the supporting structure.

[0084] In this technical solution, the mating structure of the first guide plate, the second guide plate, and the supporting structure is further defined. Both the first and second guide plates are connected to the supporting structure; that is, the first guide plate, the second guide plate, and the supporting structure form a single integrated structure. This configuration simplifies the assembly process of the first guide plate, the second guide plate, the supporting structure, and the housing assembly, reducing the assembly difficulty and improving the efficiency of the heating device's assembly and disassembly. Simultaneously, since both the first and second guide plates are connected to the supporting structure, the mating dimensions of the first guide plate, the second guide plate, and the supporting structure are guaranteed, ensuring the mating structure of the first guide plate, the second guide plate, the coil structure, and the main control board assembly, providing effective and reliable structural support for ensuring the airflow path.

[0085] In some technical solutions, optionally, a third guide plate is provided inside the housing assembly, and the third guide plate and the inner surface of the housing assembly enclose a heat exchange zone, which is connected to a fan and an air outlet; the heating device also includes a display component, which is located inside the housing assembly, and at least a part of the display component is located in the heat exchange zone.

[0086] In this technical solution, the structure of the heating device is further defined.

[0087] The shell assembly also includes a third baffle plate, which, together with the inner surface of the shell assembly, encloses a heat exchange zone. This heat exchange zone is connected to a fan, allowing the fan to drive a portion of the airflow towards the heat exchange zone.

[0088] The heating device also includes a display component, which is located inside the housing assembly. At least a portion of the display component is located in the heat exchange zone. Airflow passing through the heat exchange zone can dissipate heat from the display component, thereby reducing the temperature rise of the display component and providing structural support for ensuring the performance and service life of the heating device.

[0089] In some technical solutions, optionally, the display component includes at least one button, and the number of heat exchange zones is at least one, with each button located at a heat exchange zone; when the number of heat exchange zones is multiple, the multiple heat exchange zones are arranged at intervals along the circumference of the fan.

[0090] In this technical solution, the display component includes at least one button section, and the number of heat exchange zones is at least one. The number of button sections matches the number of heat exchange zones; specifically, each button section is located in one heat exchange zone.

[0091] The button section is located in the heat exchange zone. The airflow passing through the heat exchange zone can dissipate heat from the button section of the display component, thereby reducing the temperature rise of the button section and preventing users from being burned when they trigger the button section. This provides structural support for ensuring the performance and service life of the heating device.

[0092] When there are multiple heat exchange zones and multiple button sections, that is, multiple heat exchange zones and multiple button sections, each button section is located in a heat exchange zone, and the multiple heat exchange zones are arranged at intervals along the circumference of the fan.

[0093] This design can meet the heat dissipation requirements of multiple buttons on the display component at the same time, ensuring the temperature rise of the buttons at different locations on the display component, and providing effective structural support for ensuring the performance of the heating device.

Detailed Implementation

[0117] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0118] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0119] The following reference Figures 1 to 17 This application describes heating device 80 and cooking appliance according to some embodiments.

[0120] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, a heating device 80 according to some embodiments of this application includes a housing assembly 800, a fan 920, and a coil structure 600. Both the fan 920 and the coil structure 600 are located within the housing assembly 800.

[0121] The housing assembly 800 is provided with an air inlet 830 and an air outlet 840.

[0122] like Figure 1 , Figure 2 , Figure 8 , Figure 13 , Figure 14 and Figure 15 As shown, the housing assembly 800 contains a first guide plate 950 and a support structure 10.

[0123] The fan 920 is located inside the housing assembly 800.

[0124] Fan 920 connects air inlet 830 and air outlet 840.

[0125] The first guide plate 950 is located between the support structure 10 and the fan 920.

[0126] The coil structure 600 is stacked on the support structure 10, and the support structure 10 has a steering rib 400 on the side facing the coil structure 600.

[0127] Among them, the fan 920 works to drive the airflow through the first guide plate 950 to the support structure 10, and then guides it through the steering rib 400 to the coil structure 600.

[0128] The heating device 80 provided in this application includes a housing assembly 800, a fan 920, and a coil structure 600. The fan 920 and the coil structure 600 are both located within the housing assembly 800.

[0129] The housing assembly 800 is provided with an air inlet 830 and an air outlet 840, and the fan 920 is connected to the air inlet 830 and the air outlet 840.

[0130] The housing assembly 800 contains a first guide plate 950 and a support structure 10. The first guide plate 950 is located between the support structure 10 and the fan 920. A coil structure 600 is stacked on the support structure 10, which supports and fixes the coil structure 600. A steering rib 400 is provided on the side of the support structure 10 facing the coil structure 600.

[0131] The fan 920 operates to drive airflow from the environment into the housing assembly 800 through the air inlet 830. Guided by the first guide plate 950, the airflow flows towards the support structure 10. Guided by the deflecting ribs 400, the airflow moves towards the coil structure 600, flowing from the bottom to the top of the coil structure 600, and finally exits the heating device 80 through the air outlet 840. The airflow through the coil structure 600 effectively dissipates heat, ensuring its cooling performance. It is understood that the deflecting ribs 400 are positioned to match the coil structure 600, changing the airflow path and effectively guiding the airflow to the coil structure 600 for efficient heat dissipation.

[0132] Understandably, compared to a fan housed separately within an outer casing, where the fan is in a completely open space, the first guide plate 950 and the support structure 10 work together to limit the airflow path, concentrating the airflow and allowing it to effectively flow to the coil structure 600. In particular, when the airflow reaches the deflecting rib 400, the originally horizontal airflow is guided upwards towards the bottom of the coil structure 600 by the deflecting rib 400. This increases the contact area between the airflow and the coil structure 600, ensuring effective contact between the bottom and top of the coil structure 600. This accelerates heat exchange between the coil structure 600 and the airflow, improving heat dissipation efficiency.

[0133] Furthermore, the coil structure 600 is stacked on the support structure 10. The support structure 10 not only supports the coil structure 600 but also alters the airflow path, effectively guiding the airflow to the coil structure 600 for efficient heat dissipation. This arrangement reuses the structure of the support structure 10, enriches its functionality, reduces the need for flow guiding materials, and enhances product performance and market competitiveness.

[0134] Understandably, the steering rib 400 protrudes from the outer surface of the bracket 100. Therefore, the bracket structure 10 can be moved or disassembled by holding the steering rib 400, which facilitates operation and improves the efficiency of product assembly and disassembly. In other words, the steering rib 400 not only changes the direction of airflow but also provides a gripping function, enriching the functionality of the steering rib 400.

[0135] In some embodiments, for example, the steering rib 400 is disposed opposite to the coil structure 600.

[0136] In this embodiment, the mating structure of the steering rib 400 and the coil structure 600 is further defined.

[0137] The steering rib 400 is positioned opposite to the coil structure 600. Specifically, the bottom of the steering rib 400 is positioned opposite to the bottom of the coil structure 600. In this way, when the airflow passes through the steering rib 400, the airflow path is changed under the guidance of the steering rib 400, causing the airflow to flow from the bottom to the top of the coil structure 600 and penetrate through the coil structure 600. This increases the contact area between the airflow and the coil structure 600, allowing both the bottom and top of the coil structure 600 to effectively contact the airflow, thereby accelerating the heat exchange rate between the coil structure 600 and the airflow and improving heat dissipation efficiency.

[0138] In some embodiments, exemplarily, such as Figure 1 As shown, the middle part 620 of the coil structure is located between the steering rib 400 and the first guide plate 950.

[0139] In this embodiment, the cooperative structure of the coil structure 600, the steering rib 400 and the first guide plate 950 is further defined, such that the middle part 620 of the coil structure is located between the steering rib 400 and the first guide plate 950. That is, along the direction from the first guide plate 950 to the support structure 10, the steering rib 400 is located behind the middle part 620 of the coil structure.

[0140] The main heat-generating structure of the coil structure 600 is located on the periphery of the middle part 620 of the coil structure. Therefore, the steering rib 400 is arranged behind the middle part 620 of the coil structure, so that the airflow can be guided upward behind the middle part 620 of the coil structure to ensure the contact area and contact zone between the airflow and the coil structure 600, which can accelerate the heat exchange speed between the coil structure 600 and the airflow and improve the heat dissipation efficiency.

[0141] In some embodiments, exemplarily, such as Figure 13 As shown, along the direction from the first guide plate 950 to the steering rib 400, the first guide plate 950 is projected onto the end face of the steering rib 400 facing the first guide plate 950, and the projection of the first guide plate 950 is located between the two circumferential end faces of the steering rib 400.

[0142] In this embodiment, the mating structure of the first guide plate 950 and the steering rib 400 is further defined such that, along the direction from the first guide plate 950 to the steering rib 400, the first guide plate 950 is projected orthographically onto the end face of the steering rib 400 facing the first guide plate 950, and the projection of the first guide plate 950 is located between the two circumferential end faces of the steering rib 400. This further defines the flow path of the airflow through the first guide plate 950 to the support structure 10.

[0143] When the airflow passes through the first guide plate 950, the first guide plate 950 has the function of guiding the flow path of the airflow. The airflow is gathered and flows to the turning rib 400 of the support structure 10 to ensure the airflow to the turning rib 400, and thus ensure the airflow to the coil structure 600 through the turning rib 400, providing structural support for ensuring the heat dissipation effect of the coil structure 600.

[0144] In some embodiments, exemplarily, such as Figure 8 and Figure 13 As shown, the first guide plate 950 is a groove-shaped structure recessed towards the fan 920.

[0145] The bottom 954 of the trough-shaped structure is provided with a first opening 956.

[0146] The first opening is 956 connected to the ventilation fan 920.

[0147] In this embodiment, the structure of the first guide plate 950 is further defined.

[0148] The first guide plate 950 is a recessed trough-shaped structure facing the fan 920. The bottom 954 of the trough-shaped structure has a first opening 956, which connects to the fan 920. That is, the bottom 954 of the trough-shaped structure is located between the opening 952 of the trough-shaped structure and the fan 920. Alternatively, the opening 952 of the trough-shaped structure is located between the bottom 954 of the trough-shaped structure and the turning rib 400.

[0149] The fan 920 operates to drive the airflow through the first opening 956 to the trough structure, and under the guidance of the trough wall of the trough structure, it flows to the support structure 10, and then under the guidance of the turning rib 400, it flows to the coil structure 600.

[0150] The groove structure and the support structure 10 work together to limit the airflow path and provide structural support to ensure the heat dissipation effect of the coil structure 600.

[0151] In some embodiments, exemplarily, such as Figure 13 As shown, a portion of the support structure 10 extends into the groove structure through the slot 952 of the groove structure.

[0152] In this embodiment, the cooperation structure between the support structure 10 and the first guide plate 950 is further defined.

[0153] A portion of the support structure 10 extends into the trough structure through the slot 952. The support structure 10 and the first guide plate 950 cooperate to effectively guide the airflow. The support structure 10 and the first guide plate 950 enclose a relatively continuous guide structure, allowing the airflow to be effectively guided to the turning rib 400.

[0154] In addition, the fact that part of the support structure 10 is located inside the trough structure also helps to reduce the overall size of the support structure 10 and the first guide plate 950, thereby reducing the internal space occupancy of the heating device 80 and facilitating the reasonable layout of other components of the heating device 80.

[0155] In some embodiments, exemplarily, the steering rib 400 is an arc-shaped rib that bends in a direction away from the first guide plate 950.

[0156] In this embodiment, the structure of the steering rib 400 is further defined such that the steering rib 400 is an arc-shaped rib that bends in the direction away from the first guide plate 950. The arc-shaped rib has a smooth curved surface. The smooth curved surface can prevent the airflow from turning suddenly, which is beneficial to reducing boundary layer separation, reducing the probability of turbulence formation, reducing energy loss, and enabling the airflow to move more efficiently toward the coil structure 600.

[0157] Understandably, the continuous curvature of the curved ribs helps maintain laminar flow, reduces airflow pulsation, and promotes stable airflow. Simultaneously, the curved ribs can disperse the stress generated by airflow impact, reducing fatigue damage. Furthermore, by extending the service life of the 400-degree steering rib, they help reduce vibration and noise.

[0158] In some embodiments, exemplarily, such as Figure 2 , Figure 14 and Figure 15 As shown, the support structure 10 includes a support 100, which includes a support body 110 and multiple support segments 120.

[0159] Each support segment 120 is connected to the support body 110.

[0160] Multiple support sections 120 are arranged at intervals along the circumference of the support body 110.

[0161] The steering rib 400 is located on one side of the bracket 100.

[0162] Each support segment 120 is provided with a connecting structure 200.

[0163] The connection structure 200 includes a first connection part 210 and a second connection part 220.

[0164] The first connecting part 210 is detachably connected to the coil structure 600, and the second connecting part 220 is detachably connected to the housing assembly 800.

[0165] In this embodiment, the support structure 10 includes a support 100, which includes a support body 110 and a plurality of support segments 120. Any one of the plurality of support segments 120 is connected to the support body 110, and the plurality of support segments 120 are arranged at circumferential intervals along the support body 110.

[0166] Each support segment 120 is provided with a connecting structure 200, which includes a first connecting portion 210 and a second connecting portion 220. The first connecting portion 210 is detachably connected to the coil structure 600. That is, when the bracket structure 10 and the coil structure 600 are assembled, the first connecting portion 210 of the connecting structure 200 is detachably connected to the coil structure 600 to achieve the purpose of assembling the coil structure 600 onto the bracket structure 10. Thus, the coil structure 600 is assembled into the housing assembly 800 of the heating device 80 via the bracket structure 10, and the coil structure 600 is equipped with an independent bracket structure 10. The second connecting portion 220 is detachably connected to the housing assembly 800. That is, when the bracket structure 10 and the housing assembly 800 of the heating device 80 are assembled, the second connecting portion 220 of the connecting structure 200 is detachably connected to the housing assembly 800 to achieve the purpose of assembling the bracket structure 10 into the housing assembly 800. Compared to having the coil structure and mainboard mounted on the same support, this design reduces the tonnage of the mold used to manufacture the support, thus lowering mold costs. Furthermore, since the coil structure 600 is assembled within the housing assembly 800 via an independent support structure 10, the mainboard 940 can be positioned relatively far from the heating device 80. This allows for greater airflow for heat dissipation compared to the coil structure being supported above the mainboard. This reduces heat exchange between the mainboard 940 and the coil structure 600, optimizes temperature rise at both locations, and ensures effective heat dissipation for both, improving product performance and extending product lifespan.

[0167] Furthermore, multiple support segments 120 are arranged circumferentially around the support body 110. Each support segment 120 is provided with a connecting structure 200. That is, each support segment 120 can not only be connected to the housing assembly 800 of the heating device 80 through the connecting structure 200, but also to the coil structure 600 through the connecting structure 200. This arrangement ensures the fitting angle and fitting area between the support structure 10 and the housing assembly 800 and the coil structure 600, ensuring the effective support and fixation of the coil structure 600, and also ensuring the stability and reliability of the coil structure 600 assembled within the housing assembly 800. Simultaneously, the multiple support segments 120 are arranged at intervals, meaning that a gap is formed between adjacent support segments 120 and the support body 110. This reduces the material input of the support structure 10, lowers its weight, reduces its volume, and lowers its production cost.

[0168] In addition, a gap will be formed between two adjacent support sections 120 and the bracket body 110. This will ensure the effectiveness and reliability of the support coil structure 600, while reducing the area of ​​the bracket structure 10 and the coil structure 600 relative to each other. This will allow some airflow to flow to the coil structure 600 from the gap, which will help increase the air volume for heat dissipation of the coil structure 600 per unit time and further improve the heat dissipation efficiency of the coil structure 600.

[0169] Furthermore, the coil structure 600 is equipped with an independent support structure 10. The coil structure 600 is detachably connected to the housing assembly 800 via the support structure 10. Therefore, various models of coil structures 600 and support structures 10 can be flexibly assembled within the same housing assembly 800 according to specific usage requirements. In other words, when the external dimensions of the housing assembly 800 remain unchanged, a support structure 10 matching the size of the coil structure 600 can be selected based on its model adaptability. Multiple models of coil structures 600 can be assembled within the same housing assembly 800, thus improving the adaptability of the housing assembly 800 and enhancing the product's performance and market competitiveness.

[0170] In some embodiments, exemplarily, such as Figure 13 As shown, there are multiple support structures 10, coil structures 600, and first guide plates 950.

[0171] Each coil structure 600 is coupled with a support structure 10 and a first guide plate 950.

[0172] Among them, multiple coil structures 600 are arranged at circumferential intervals along the fan 920.

[0173] In this embodiment, the number and arrangement of the support structure 10, the coil structure 600, and the first guide plate 950 are further defined.

[0174] The heating device 80 comprises multiple support structures 10, coil structures 600, and first guide plates 950, with each coil structure 600 cooperating with one support structure 10 and one first guide plate 950. That is, the heating device 80 has multiple coil structures 600, which increases the heating area and heating surface area, thus improving the heating efficiency of the heating device 80. Simultaneously, this configuration can meet the needs of simultaneously heating multiple appliances, broadening the product's adaptability.

[0175] In some other embodiments, the number of the support structure 10, the coil structure 600, and the first guide plate 950 is one.

[0176] For example, at least two of the plurality of first deflectors 950 have different shapes.

[0177] For example, any two points of the plurality of first deflectors 950 have the same shape.

[0178] In some embodiments, exemplarily, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 13 As shown, the housing assembly 800 also includes a second guide plate 960 and a support structure 930, and the heating device 80 also includes a main control board assembly 970, which is stacked on the support structure 930.

[0179] The second guide plate 960 is located between the support structure 930 and the fan 920.

[0180] The main control board assembly 970 is stacked on the support structure 930.

[0181] The main control board assembly 970 includes the main board 940 and the finned structure 980.

[0182] The fin structure 980 is located on one side of the mainboard 940.

[0183] Among them, the operation of the fan 920 also drives the airflow through the second guide plate 960 to the main control board group 970.

[0184] In this embodiment, the housing assembly 800 also includes a second guide plate 960 and a support structure 930. The second guide plate 960 is located between the support structure 930 and the fan 920.

[0185] The heating device 80 also includes a main control board assembly 970, which is stacked on a support structure 930. The support structure 930 has the function of supporting and fixing the main control board assembly 970.

[0186] The fan 920 operates to drive airflow from the environment into the housing assembly 800 through the air inlet 830. A first portion of the airflow, guided by the first guide plate 950, flows towards the support structure 10. This second portion of airflow, guided by the steering rib 400, flows towards the coil structure 600, passing from the bottom to the top of the coil structure 600. A second portion of the airflow, guided by the second guide plate 960, flows towards the main control board assembly 970. As the airflow passes through the coil structure 600 and the main control board assembly 970, it effectively dissipates heat from both structures, ensuring optimal cooling performance.

[0187] Understandably, the first guide vane 950 is located between the support structure 10 and the fan 920, and the second guide vane 960 is located between the support structure 930 and the fan 920. This arrangement ensures that both the coil structure 600 and the main control board assembly 970 have corresponding airflow for heat dissipation. Since the coil structure 600 and the main control board assembly 970 are located in different flow channels, they can each dissipate heat effectively, thus ensuring the heat dissipation performance of both.

[0188] The main control board assembly 970 includes a main board 940 and a finned structure 980. The finned structure 980 is located on one side of the main board 940. The finned structure 980 increases the heat dissipation area of ​​the main control board assembly 970, which can increase the contact area between the main control board assembly 970 and the external airflow, thus improving the heat dissipation efficiency of the main control board assembly 970.

[0189] For example, the first guide plate 950 and the second guide plate 960 are two relatively independent structures.

[0190] For example, a portion of the first guide plate 950 and a portion of the second guide plate 960 are integral structures. For instance, the first end face of the plate body forms a portion of the first guide plate 950, and the second end face of the plate body forms a portion of the second guide plate 960. That is, the first guide plate 950 and the second guide plate 960 share a portion of the structure.

[0191] In some embodiments, exemplarily, such as Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, at least a portion of the fin structure 980 is located between the second guide plate 960 and the main plate 940.

[0192] In this embodiment, the cooperative structure of the main control board assembly 970 and the second guide plate 960 is further defined.

[0193] At least a portion of the fin structure 980 is located between the second guide plate 960 and the main plate 940. That is, a portion of the fin structure 980 is located between the second guide plate 960 and the main plate 940, or the entire fin structure 980 is located between the second guide plate 960 and the main plate 940.

[0194] In other words, at least a portion of the second air deflector 960 is closer to the second air deflector 960 than the motherboard 940.

[0195] In this way, the airflow guided by the second guide plate 960 will first flow through the fin structure 980, and then through the main board 940. This helps to increase the contact area between the fin structure 980 and the airflow, so that the heat at the fin structure 980 can be effectively dissipated, ensuring the heat dissipation efficiency of the main control board 970.

[0196] In some other embodiments, at least a portion of the mainboard 940 is located between the fin structure 980 and the second guide plate 960.

[0197] In some embodiments, exemplarily, such as Figure 7 and Figure 10 As shown, the fin structure 980 includes a support plate 982 and multiple fins 984.

[0198] The support plate 982 is connected to the motherboard 940.

[0199] Multiple fins 984 are connected to the side of the support plate 982 opposite to the support structure 930.

[0200] Multiple fins 984 are arranged at intervals along a direction perpendicular to the fan 920 to the main board 940.

[0201] In this embodiment, the composition of the fin structure 980 is further defined.

[0202] The fin structure 980 includes a support plate 982 and multiple fins 984. The support plate 982 is connected to the main plate 940, and the multiple fins 984 are all connected to the side of the support plate 982 away from the support structure 930.

[0203] Multiple fins 984 are arranged at intervals along a direction perpendicular to the fan 920 and the main board 940. It is understood that a flow channel is formed between adjacent fins 984, extending in the direction of the second guide plate 960 and the main board 940. The extension direction of the flow channel matches the positions of the main board 940 and the fan 920. This facilitates the dissipation of heat transferred from the main board 940 to the fin structure 980, improving the heat dissipation efficiency of the main control board assembly 970 and ensuring its temperature. This provides structural support for ensuring the performance and service life of the heating device 80.

[0204] In some embodiments, exemplarily, such as Figure 7 As shown, the support plate 982 has a clearance area 9822.

[0205] A portion of the multiple fins 984 are located on the first side of the avoidance zone 9822.

[0206] Another portion of the multiple fins 984 are located on the second side of the avoidance zone 9822.

[0207] like Figure 6 As shown, the heating device 80 also includes a mounting component 990.

[0208] Mounting component 990 passes through clearance zone 9822 and locks into support structure 930.

[0209] The housing assembly 800 is also provided with a first guide rib 1010.

[0210] The first guide rib 1010 is located between the fan 920 and the fin structure 980.

[0211] The first guide rib 1010 is used to guide the flow to the first side and the second side of the avoidance zone 9822.

[0212] In this embodiment, the structure of the heating device 80 is further defined.

[0213] The support plate 982 has a clearance area 9822, which is used to connect with the support structure 930 to achieve the purpose of assembling the main control board assembly 970 and the support structure 930.

[0214] Specifically, the heating device 80 also includes a mounting member 990 that passes through a clearance area 9822 and locks into a support structure 930 to assemble the main control board assembly 970 onto the support structure 930. It is understood that the clearance area 9822 is used to allow space for the mounting member 990, providing spatial support for the connection between the mounting member 990 and the main control board assembly 970 and the support structure 930.

[0215] The avoidance zone 9822 has a first side and a second side, and the first side and the second side of the avoidance zone 9822 are opposite sides of the avoidance zone 9822.

[0216] A portion of the multiple fins 984 are located on the first side of the clearance area 9822, while another portion of the multiple fins 984 are located on the second side of the clearance area 9822. In other words, the multiple fins 984 do not obstruct the clearance area 9822.

[0217] The housing assembly 800 is also provided with a first guide rib 1010, which is located between the fan 920 and the fin structure 980. The first guide rib 1010 has the function of guiding the airflow to the first side and the second side of the avoidance area 9822, respectively. More specifically, the airflow is guided to the fins 984 on the first side and the second side of the avoidance area 9822, respectively, so that the airflow will not flow through the avoidance area 9822 and is forced to pass through the densely arranged multiple fins 984, thereby improving the heat exchange rate between the airflow and the fin structure 980.

[0218] In some embodiments, for example, there are multiple clearance areas 9822 and multiple first guide ribs 1010. The multiple clearance areas 9822 are arranged at intervals along a direction perpendicular to the fan 920 to the main board 940, and each clearance area 9822 cooperates with a first guide rib 1010.

[0219] In this embodiment, the number and arrangement of the avoidance zone 9822 and the first guide rib 1010 are further defined.

[0220] There are multiple clearance zones 9822 and multiple first guide ribs 1010. Each clearance zone 9822 is paired with one first guide rib 1010, that is, there is one first guide rib 1010 between each clearance zone 9822 and the fan 920.

[0221] This setting can reduce or even avoid airflow through the avoidance zone 9822, so that the airflow can be effectively guided to the dense area of ​​fins 984, thereby improving the heat dissipation efficiency of the fin structure 980.

[0222] In some embodiments, exemplarily, the number of fin structures 980 is multiple.

[0223] Multiple fin structures 980 are arranged at intervals along a direction perpendicular to the fan 920 to the main board 940.

[0224] The housing assembly 800 is also provided with at least one second guide rib 1020.

[0225] like Figure 6 As shown, the second guide rib 1020 is located between the main control board assembly 970 and the fan. The gap between any two adjacent fin structures 980 is opposite to a second guide rib 1020. The second guide rib 1020 is used to guide the airflow to the two adjacent fin structures 980.

[0226] In this embodiment, the structure of the heating device 80 is further defined.

[0227] There are multiple finned structures 980, which are arranged at intervals along a direction perpendicular to the fan 920 to the main board 940. Due to the limited installation space of the finned structures 980, there is a gap between adjacent finned structures 980. If the airflow passes through the gap between adjacent finned structures 980, it will waste resources and reduce the heat dissipation efficiency of the main control board 970.

[0228] Therefore, at least one second guide rib 1020 is provided within the housing assembly 800, such that the second guide rib 1020 is located between the main control board assembly 970 and the fan. The gap between any two adjacent fin structures 980 is opposite to one of the second guide ribs 1020. The second guide rib 1020 is used to guide airflow to the two adjacent fin structures 980; that is, the gap between two adjacent fin structures 980 is opposite to one of the second guide ribs 1020, which is positioned between the gap and the fan 920. The second guide rib 1020 has a guiding function, directing the airflow to the two adjacent fin structures 980 respectively, preventing the airflow from flowing through the gap between the two adjacent fin structures 980. This forces the airflow to pass only through the densely arranged multiple fins 984 on the fin structure 980, thereby improving the heat exchange rate between the airflow and the fin structure 980 and enhancing the heat dissipation efficiency of the main control board assembly 970.

[0229] In some embodiments, exemplarily, such as Figure 8 As shown, both the first guide rib 1010 and the second guide rib 1020 include two stiffener plates 1030.

[0230] Each stiffener 1030 includes a first end 1032 and a second end 1034.

[0231] The first ends 1032 of the two stiffening plates 1030 are connected.

[0232] The second ends 1034 of the two stiffeners 1030 are far apart from each other.

[0233] The first end 1032 of the stiffening plate 1030 is located between the fan 920 and the second end 1034 of the stiffening plate 1030.

[0234] In the first guide rib 1010, the second end 1034 of one rib plate 1030 is disposed opposite to the portion of the support plate 982 located on the first side of the avoidance area 9822, and the second end 1034 of the other rib plate 1030 is disposed opposite to the portion of the support plate 982 located on the second side of the avoidance area 9822.

[0235] In the second guide rib 1020, the second end 1034 of one rib plate 1030 is arranged opposite to one of the two adjacent fin structures 980, and the second end 1034 of the other rib plate 1030 is arranged opposite to the other of the two adjacent fin structures 980.

[0236] In this embodiment, the first guide rib 1010 includes two stiffener plates 1030. Each stiffener plate 1030 has a first end 1032 and a second end 1034. The first ends 1032 of the two stiffener plates 1030 are connected, and the second ends 1034 of the two stiffener plates 1030 are spaced apart from each other. That is, the two stiffener plates 1030 are in a "V" shape. The first end 1032 of the stiffener plate 1030 is located between the fan 920 and the second end 1034 of the stiffener plate 1030.

[0237] In the first guide rib 1010, the second end 1034 of one rib plate 1030 is positioned opposite to the portion of the support plate 982 located on the first side of the clearance area 9822, and the second end 1034 of the other rib plate 1030 is positioned opposite to the portion of the support plate 982 located on the second side of the clearance area 9822. That is, the two rib plates 1030 of the first guide rib 1010 have a guiding function; one rib plate 1030 directs the airflow to the fin 984 on the first side of the clearance area 9822, and the other rib plate 1030 directs the airflow to the fin 984 on the second side of the clearance area 9822. This reduces or even prevents airflow from reaching the clearance area 9822, providing structural support to ensure the heat dissipation efficiency of the fin structure 980.

[0238] The second guide rib 1020 includes two stiffener plates 1030. Each stiffener plate 1030 has a first end 1032 and a second end 1034. The first ends 1032 of the two stiffener plates 1030 are connected, and the second ends 1034 of the two stiffener plates 1030 are spaced apart from each other. That is, the two stiffener plates 1030 form a "V" shape. The first end 1032 of the stiffener plate 1030 is located between the fan 920 and the second end 1034 of the stiffener plate 1030.

[0239] In the second guide rib 1020, the second end 1034 of one rib 1030 is positioned opposite to one of the two adjacent fin structures 980, and the second end 1034 of the other rib 1030 is positioned opposite to the other of the two adjacent fin structures 980. That is, the two ribs 1030 of the second guide rib 1020 have a guiding function; one rib 1030 directs the airflow to one of the two adjacent fin structures 980, and the other rib 1030 directs the airflow to the other of the two adjacent fin structures 980. This reduces or even avoids airflow flowing into the gap between the two adjacent fin structures 980. It provides structural support to ensure the heat dissipation efficiency of the fin structures 980.

[0240] In some embodiments, exemplarily, such as Figure 9 and Figure 11 As shown, the support structure 930 is provided with a mounting part 932.

[0241] The mounting portion 932 is detachably connected to the outermost fin 984 among a plurality of fins 984, and / or the mounting portion 932 is detachably connected to the outer edge of the support plate 982.

[0242] In this embodiment, the cooperation structure between the support structure 930 and the main control board assembly 970 is further defined.

[0243] The support structure 930 is provided with a mounting part 932, which is detachably connected to the outermost fin 984 among the multiple fins 984. That is, the connection between the support structure 930 and the fin structure 980 is located at the outermost fin 984 among the multiple fins 984. In this way, there is no clearance area 9822 between the multiple fins 984 for installation, which allows airflow to pass through more fins 984, thereby improving the heat exchange speed between airflow and fin structure 980 and improving the heat dissipation efficiency of main control board assembly 970.

[0244] And / or, the mounting part 932 is detachably connected to the outer edge of the support plate 982. That is, the connection between the support structure 930 and the fin structure 980 is located at the outer edge of the support plate 982. In this way, there is no clearance area 9822 between the multiple fins 984 for installation, allowing airflow to pass through more fins 984, which helps to improve the heat exchange speed between the airflow and the fin structure 980 and improve the heat dissipation efficiency of the main control board assembly 970.

[0245] Exemplarily, the mounting portion 932 includes at least one of a snap-fit, a magnetic portion, and a connecting hole. When the mounting portion 932 includes a snap-fit, the snap-fit ​​engages with one of the fins 984 and the support plate 982. When the mounting portion 932 includes a magnetic portion, the magnetic portion is magnetically attracted to one of the fins 984 and the support plate 982. When the mounting portion 932 includes a connecting hole, a screw passes through the connecting hole and locks into one of the fins 984 and the support plate 982. The screw can be replaced by a bolt or a rivet.

[0246] In some embodiments, for example, both the first guide plate 950 and the second guide plate 960 are connected to the support structure 930.

[0247] In this embodiment, the mating structure of the first guide plate 950, the second guide plate 960, and the support structure 930 is further defined. Both the first guide plate 950 and the second guide plate 960 are connected to the support structure 930; that is, the first guide plate 950, the second guide plate 960, and the support structure 930 form a single integrated structure. This arrangement simplifies the assembly process of the first guide plate 950, the second guide plate 960, the support structure 930, and the housing assembly 800, reducing the assembly difficulty and improving the disassembly and assembly efficiency of the heating device 80. Meanwhile, since both the first guide plate 950 and the second guide plate 960 are connected to the support structure 930, the matching dimensions of the first guide plate 950, the second guide plate 960 and the support structure 930 can be guaranteed, and the matching structure of the first guide plate 950, the second guide plate 960, the coil structure 600 and the main control board assembly 970 can be guaranteed, providing effective and reliable structural support for ensuring the flow path of the airflow.

[0248] In some embodiments, exemplarily, such as Figure 12 and Figure 13 As shown, a third guide plate 1040 is also provided inside the housing assembly 800.

[0249] The heat exchange zone 1050 is enclosed by the inner surface of the third guide plate 1040 and the shell assembly 800.

[0250] The heat exchange zone is 1050, with a ventilation fan of 920 and an air outlet of 840.

[0251] like Figure 1 and Figure 5 As shown, the heating device 80 also includes a display component 1060.

[0252] The display component 1060 is located within the housing component 800.

[0253] The display component 1060 has a button section 1062.

[0254] The button section 1062 is located at the heat exchange zone 1050.

[0255] In this embodiment, the structure of the heating device 80 is further defined.

[0256] The housing assembly 800 also includes a third guide plate 1040, which, together with the inner surface of the housing assembly 800, encloses a heat exchange zone 1050. The heat exchange zone 1050 is connected to a fan 920, so that the operation of the fan 920 can drive a portion of the airflow to the heat exchange zone 1050.

[0257] The heating device 80 also includes a display component 1060, which is disposed within the housing component 800. The display component 1060 has a button portion 1062 located in the heat exchange zone 1050. Airflow through the heat exchange zone 1050 can dissipate heat from the button portion 1062 of the display component 1060, thereby reducing the temperature rise of the button portion 1062 and preventing users from being burned when they trigger the button portion 1062. This provides structural support for ensuring the performance and service life of the heating device 80.

[0258] For example, the first deflector 950 and the third deflector 1040 are two relatively independent structures.

[0259] For example, a portion of the first guide plate 950 and a portion of the third guide plate 1040 are integral structures. For instance, the first end face of the plate forms a portion of the first guide plate 950, and the second end face of the plate forms a portion of the third guide plate 1040. That is, the first guide plate 950 and the third guide plate 1040 share a portion of the structure.

[0260] In some embodiments, for example, there are multiple heat exchange zones 1050 and button portions 1062, with each button portion 1062 located at a heat exchange zone 1050.

[0261] Multiple heat exchange zones 1050 are arranged at circumferential intervals along the fan 920.

[0262] In this embodiment, the number and mating structure of the heat exchange zone 1050 and the key portion 1062 are further defined.

[0263] There are multiple heat exchange zones 1050 and multiple button sections 1062. Each button section 1062 is located in one heat exchange zone 1050, and the multiple heat exchange zones 1050 are arranged at intervals along the circumference of the fan 920.

[0264] This configuration can meet the heat dissipation requirements of multiple button sections 1062 of the display component 1060 at the same time, ensure the temperature rise of the button sections 1062 at different locations of the display component 1060, and provide effective structural support for ensuring the performance of the heating device 80.

[0265] For example, the first guide plate 950, the second guide plate 960, and the third guide plate 1040 are all connected to the support structure 930. That is, the first guide plate 950, the second guide plate 960, the third guide plate 1040, and the support structure 930 are a whole structure. This arrangement can simplify the assembly process of the first guide plate 950, the second guide plate 960, the third guide plate 1040, the support structure 930, and the housing assembly 800, reduce the assembly difficulty of the first guide plate 950, the second guide plate 960, the third guide plate 1040, the support structure 930, and the housing assembly 800, and help improve the disassembly and assembly efficiency of the heating device 80. Meanwhile, since the first guide plate 950, the second guide plate 960, and the third guide plate 1040 are all connected to the support structure 930, the matching dimensions of the first guide plate 950, the second guide plate 960, the third guide plate 1040, and the support structure 930 can be guaranteed. The matching structure of the first guide plate 950, the second guide plate 960, the third guide plate 1040, the button part 1062, the coil structure 600, and the main control board assembly 970 can be guaranteed, providing effective and reliable structural support for ensuring the flow path of the airflow.

[0266] in, Figure 3 , Figure 4 , Figure 6 , Figure 9 and Figure 13 The arrows in the diagram indicate the direction of airflow.

[0267] A cooking appliance according to some embodiments of the present application includes: a heating device 80 as described in any of the above embodiments.

[0268] The cooking appliance provided in this application includes the heating device 80 as described in any of the above embodiments, and therefore has all the beneficial effects of the heating device 80, which will not be described in detail here.

[0269] For example, such as Figure 1 As shown, the heating device 80 includes a display component 1060, two coil structures, a baffle plate 1070, a main control board assembly 970, a fan 920, a bracket structure 10, and a support structure 930.

[0270] For example, such as Figure 3 , Figure 4 and Figure 6 As shown, the airflow blown by the fan 920 hits the turning rib 400 of the support structure 10, causing the originally horizontal airflow to turn and blow towards the bottom of the coil structure 600, thus accelerating the heat exchange speed between the coil structure 600 and the airflow.

[0271] For example, such as Figure 6 , Figure 7 and Figure 8As shown, the support structure 930 and the main control board assembly 970 are fixedly connected using mounting parts 990, such as screws. A first guide rib 1010 is provided on the support structure 930, located between the main control board assembly 970 and the fan 920. The first guide rib 1010 blocks the clearance area 9822 on the main control board assembly 970, forcing the airflow to pass only through the densely arranged fins 984, thereby increasing the heat exchange rate between the airflow and the fin structure 980.

[0272] For example, such as Figure 9 and Figure 11 As shown, alternatively, fins 984 can be added to the main control board assembly 970 to fill the gap, and the main control board assembly 970 and the support structure 930 can be connected by a mounting part 932, forcing airflow through more fins 984. For example, the mounting part 932 includes a snap-fit.

[0273] For example, an airflow accumulation zone exists within the heating device 80, and the button portion 1062 on the display component 1060 is located within this airflow accumulation zone. The temperature of the button portion 1062 continuously rises, posing a risk of burns to the user when operating the buttons. To solve this problem, such as Figure 12 and Figure 13 As shown, a third guide plate 1040 can be provided inside the housing assembly 800. The third guide plate 1040 has a second opening 1042 on the side facing the fan 920. The third guide plate 1040 and the inner surface of the housing assembly 800 enclose a heat exchange zone 1050. The heat exchange zone 1050 is connected to the fan 920 through the second opening 1042 and is connected to the air outlet 840. When the fan 920 is working, it can drive a portion of the airflow to flow to the two heat exchange zones 1050 to dissipate heat from the button portion 1062 located in the heat exchange zone 1050. The first guide plate 950, the second guide plate 960, the third guide plate 1040, and the support structure 930 are an integral structure.

[0274] For example, by utilizing the principle of heat exchange and modifying the structure of product components, airflow is guided and ventilated to dissipate heat from heat-generating devices (such as the coil structure 600, IGBT (Insulated Gate Bipolar Transistor), and bridge rectifier) ​​and high-temperature areas (such as near the display component 1060). This reduces the operating ambient temperature of the two coil structures 600, the main control board assembly 970, and the display component 1060, improving the overall heat dissipation efficiency and preventing users from being burned by the buttons 1062 when operating the interactive interface. Simultaneously, this design also improves the heating performance of the multi-head heating device 80, such as an induction cooker. It is understood that with improved heat dissipation within the heating device 80, the lifespan of the internal components will also be extended.

[0275] For example, the heating device 80 includes a fan 920, which includes, but is not limited to, an axial fan, a centrifugal fan, and a vortex fan.

[0276] For example, the number of fans 920 is at least one. For example, the number of fans 920 may be 2, 3, 4, etc., which will not be listed here.

[0277] For example, the heating device 80 includes a single-burner induction cooker, a multi-burner infrared cooker, and a multi-burner hybrid cooker, etc., which will not be listed here.

[0278] For example, the airflow blown by the fan 920 changes direction at the deflector 400 of the support structure 10 to blow directly onto the coil structure above, with the deflector 400 located directly below the coil structure.

[0279] For example, the fin structure 980 on the main control board assembly 970 is provided with a clearance area 9822, which is a reserved position for screw fixing. A first guide rib 1010 is provided between the fan 920 and the clearance area 9822. The first guide rib 1010 is used to block the clearance area 9822 and guide the airflow.

[0280] For example, the main control board assembly 970 includes a support plate 982 and multiple fins 984, with the multiple fins 984 evenly arranged on the same side of the support plate 982. The support structure 930 and the main control board assembly 970 are fixed by means of fastening, riveting, etc.

[0281] For example, a third guide plate 1040 is provided inside the housing assembly 800. The third guide plate 1040 encloses a heat exchange zone 1050 on the inner surface of the housing assembly 800. The button portion 1062 of the display assembly 1060 is located in the heat exchange zone 1050. When the fan 920 is working, it can drive a portion of the airflow to flow to the heat exchange zone 1050 and then discharge it from the heating device 80 through the air outlet 840.

[0282] For example, such as Figure 13 As shown, the airflow path of the heating device 80 includes five paths: path 1, path 2, path 3, path 4, and path 5. When the airflow flows through paths 1 and 5, it can dissipate heat from the button section 1062 of the display component 1060. When the airflow flows through paths 2 and 4, it can dissipate heat from the coil structure 600. When the airflow flows through path 3, it can dissipate heat from the main control board assembly 970.

[0283] For example, the number of support segments 120 may include 2, 3, 4, and 5, etc., which will not be listed here.

[0284] For example, the bracket body 110 and the multiple support segments 120 are integrally connected. This structural arrangement eliminates the assembly process of the bracket body 110 and the multiple support segments 120, thus simplifying the assembly and subsequent disassembly processes, improving assembly and disassembly efficiency, and consequently reducing production and maintenance costs. Furthermore, the integral connection of the bracket body 110 and the multiple support segments 120 ensures the accuracy requirements of the forming dimensions of the bracket 100.

[0285] For example, at least a portion of the multiple support segments 120 are arranged at equal intervals along the circumference of the support body 110. That is, multiple support segments 120 are arranged at equal intervals along the circumference of the support body 110. Alternatively, a portion of the multiple support segments 120 are arranged at equal intervals along the circumference of the support body 110. It can be understood that this arrangement indirectly defines the arrangement position of the multiple connecting structures 200 in the circumference of the support body 110, that is, at least a portion of the multiple connecting structures 200 are arranged at equal intervals along the circumference of the support body 110. In this way, when the coil structure 600 is assembled with the housing assembly 800 via the support structure 10, it helps to improve the balance and consistency of the forces on the multiple support segments 120, ensuring the stability of the assembly of the support structure 10, the coil structure 600, and the housing assembly 800.

[0286] For example, in any two connecting structures 200, the distance from the center 212 of the first connecting portion to the center 112 of the support body is equal. That is, the centers 212 of the first connecting portions of multiple connecting structures 200 are located on the same circle, which is denoted as the marking circle 942. In this way, after the coil structure 600 is assembled on the support structure 10, the balance and consistency of the force on the multiple support sections 120 can be ensured, the stability of the assembly of the support structure 10 and the coil structure 600 can be ensured, the flatness of the coil structure 600 assembly can be ensured, the tilting of the coil structure 600 can be avoided, and the mating dimensions between the coil structure 600 and the panel of the housing assembly 800 at different positions can be ensured, thus providing structural support for ensuring effective heating.

[0287] For example, the lengths of the multiple support segments 120 are equal in the direction from the support body 110 to the support segments 120. The structure of the multiple support segments 120 is adapted to the size of the coil structure 600, which, while ensuring the effectiveness of supporting the coil structure 600, helps to reduce the processing difficulty and processing cost of the support structure 10.

[0288] For example, along the direction from the support body 110 to the support section 120, at least two of the multiple support sections 120 have unequal lengths. The structure of the multiple support sections 120 can be adaptively adjusted according to the specific shape of the coil structure 600 to meet the assembly requirements of various models of the coil structure 600. For instance, if at least two assembly positions of the coil structure 600 are different, by adaptively setting the structure of the support sections 120 such that along the direction from the support body 110 to the support section 120, at least two of the multiple support sections 120 have unequal lengths, to adapt to the assembly positions of the coil structure and meet the assembly requirements of different models of the coil structure 600.

[0289] For example, the second connecting portion 220 is located around the first connecting portion 210. That is, the connection between the support structure 10 and the housing assembly 800 is located around the connection between the support structure 10 and the coil structure 600, and the connection between the support structure 10 and the housing assembly 800 is staggered from the connection between the support structure 10 and the coil structure 600. In this way, interference between the first mating part of the coil structure 600 and the second mating part of the housing assembly 800 can be avoided, and the effective assembly dimensions of the coil structure 600, the support structure 10, and the housing assembly 800 can be guaranteed.

[0290] For example, either the second connecting portion 220 or the first connecting portion 210 includes: a snap-fit ​​portion for snap-fit ​​assembly; and / or a locking portion for locking or unlocking; and / or a magnetic portion for magnetic attraction assembly. When the first connecting portion 210 includes the snap-fit ​​portion, the bracket 100 engages with the first mating portion of the coil structure 600 via the snap-fit ​​portion. When it is necessary to separate the bracket structure 10 and the coil structure 600, only an external force needs to be applied to overcome the snap-fit ​​force between the bracket structure 10 and the coil structure 600 to achieve the separation of the bracket structure 10 and the coil structure 600. When the first connecting portion 210 includes the locking portion, the bracket 100 engages with the first mating portion of the coil structure 600 via the locking portion. When it is necessary to separate the bracket structure 10 and the coil structure 600, only the first fastener connecting the locking portion and the first mating portion needs to be removed to achieve the separation of the bracket structure 10 and the coil structure 600. When the first connecting part 210 includes a magnetic part, the bracket 100 is magnetically attracted to the first mating part of the coil structure 600 via the magnetic part. When it is necessary to separate the bracket structure 10 and the coil structure 600, only an external force needs to be applied to overcome the magnetic attraction between the bracket structure 10 and the coil structure 600 to achieve the separation of the bracket structure 10 and the coil structure 600. The second connecting part 220 includes any one or a combination of the following: a snap-fit ​​part, a locking part, and a magnetic part. When the second connecting part 220 includes a snap-fit ​​part, the bracket 100 is snap-fitted to the second mating part of the housing assembly 800 via the snap-fit ​​part. When it is necessary to separate the bracket structure 10 and the housing assembly 800, only an external force needs to be applied to overcome the snap-fit ​​force between the bracket structure 10 and the housing assembly 800 to achieve the separation of the bracket structure 10 and the housing assembly 800. When the second connecting portion 220 includes a locking portion, the bracket 100 is locked to the second mating portion of the housing assembly 800 via the locking portion. When it is necessary to separate the bracket structure 10 and the housing assembly 800, it is only necessary to remove the second fastener connecting the locking portion and the second mating portion to achieve the separation of the bracket structure 10 and the housing assembly 800. When the second connecting portion 220 includes a magnetic portion, the bracket 100 is assembled to the second mating portion of the housing assembly 800 via the magnetic portion in a magnetically attracted manner. When it is necessary to separate the bracket structure 10 and the housing assembly 800, it is only necessary to apply external force to overcome the magnetic attraction between the bracket structure 10 and the housing assembly 800 to achieve the separation of the bracket structure 10 and the housing assembly 800. Exemplarily, the first fastener includes screws, bolts, or rivets, etc., which are not listed here. Exemplarily, the second fastener includes screws, bolts, or rivets, etc., which are not listed here.

[0291] For example, when the first connecting portion 210 includes a locking portion, the locking portion includes a first stud that protrudes from the outer surface of the supporting section 120. The first stud can raise the position of the coil structure 600 relative to the bracket 100, providing clearance space for the assembly of the coil structure 600 and the bracket structure 10, and meeting the usage requirements of the coil structure 600 being stacked on one side of the bracket structure 10. It is understood that this arrangement allows a portion of the coil structure 600 to be recessed into the area enclosed by the first studs of the multiple connecting structures 200 and the bracket 100 when the coil structure 600 is assembled with the bracket structure 10. This helps to reduce the overall external dimensions of the coil structure 600 and the bracket structure 10 after assembly, thereby reducing the internal space occupancy of the housing assembly 800 and contributing to the thinning of the heating device 80.

[0292] For example, when the second connecting portion 220 includes a snap-fit ​​portion, the snap-fit ​​portion connects to the outer edge of the support section 120; when the second connecting portion 220 includes a locking portion, the locking portion includes a first threaded hole. That is, the connection between the bracket 100 and the housing assembly 800 is located at the outer edge of the support section 120. This avoids interference between the support section 120 and the connection between the second connecting portion 220 and the second mating portion, providing the advantage of convenient assembly and disassembly. When the second connecting portion 220 includes a locking portion, the locking portion includes a first threaded hole, and the second fastener can be screwed into the first threaded hole. This configuration offers the advantages of convenient assembly and disassembly, and low production cost.

[0293] For example, such as Figure 15 As shown, each support segment 120 is also provided with a storage slot 300. The storage slot 300 and the first connecting portion 210 are located on opposite sides of the support segment 120, and the storage slot 300 and the first connecting portion 210 are arranged opposite to each other. That is, the storage slot 300 is located on the first side of the support segment 120, the first connecting portion 210 is located on the second side of the support segment 120, and the storage slot 300 and the first connecting portion 210 are arranged opposite to each other. In this way, when multiple support structures 10 are stored, the multiple support structures 10 can be stacked, and in two adjacent support structures 10, the first connecting portion 210 of the lower support structure 10 will be inserted into the storage slot 300 of the upper support structure 10. In other words, this arrangement can realize the stacking of multiple support structures 10, which can save storage space. It is understandable that when two support structures 10 are stacked, the first connecting portion 210 of the lower support structure 10 and the storage groove 300 of the upper support structure 10 cooperate to limit the relative displacement of the two support structures 10 and prevent the two support structures 10 from shifting. Therefore, this arrangement not only saves storage space but also prevents multiple support structures 10 from scattering.

[0294] For example, such as Figure 16 and Figure 17As shown, the bracket 100 is provided with a positioning post 500, and the positioning post 500 and the first connecting part 210 are located on opposite sides of the bracket 100. That is, the positioning post 500 is located on the first side of the bracket 100, and the first connecting part 210 is located on the second side of the bracket 100. The first side and the second side of the bracket 100 are opposite sides of the bracket 100. The positioning post 500 is used to connect with the flange hole 820 of the housing assembly 800. When assembling the bracket structure 10 and the housing assembly 800, the positioning post 500 is inserted into the flange hole 820. The size of the positioning post 500 matches the size of the flange hole 820. The flange hole 820 and the positioning post 500 cooperate to align the second connecting part 220 and the second mating part, which is beneficial for the rapid alignment of the second connecting part 220 and the second mating part, thereby improving the assembly efficiency of the heating device 80. In addition, when the product falls, there is a reaction force between the positioning post 500 and the flange hole 820 of the housing assembly 800, which can reduce the stress at the second connection part 220 of the bracket structure 10, thereby reducing the risk of the bracket structure 10 breaking and helping to improve the service life of the bracket structure 10.

[0295] For example, the positioning post 500 is located at the support body 110. Alternatively, the positioning post 500 can be located at the middle of the support 100. This arrangement facilitates effective alignment of the second connecting portions 220 on the plurality of support sections 120 with the plurality of second mating portions within the housing assembly 800, and facilitates rapid alignment of the plurality of second connecting portions 220 and the plurality of second mating portions. For example, there is one positioning post 500 and one flanged hole 820. For example, there are multiple positioning posts 500 and multiple flanged holes 820, with each positioning post 500 engaging with one flanged hole 820. At least a portion of the multiple positioning posts 500 are located at the support body 110. Alternatively, at least a portion of the multiple positioning posts 500 are located at the support section 120.

[0296] For example, along the direction from the support body 110 to the support segment 120, at least a portion of the support segment 120 gradually decreases in width in the first direction. The support body 110 bears the maximum bending moment, and the shape of the support segment 120 avoids material redundancy. Furthermore, the change in the width of the support segment 120 smoothly transmits the load, avoiding stress concentration problems caused by abrupt changes in cross-section, which is beneficial for improving fatigue life. Simultaneously, the change in the width of the support segment 120 helps adjust the natural frequency of the support segment 120, preventing resonance with external excitation.

[0297] For example, the wind deflector 1070 and the inner surface of the housing assembly 800 enclose a cavity for mounting the fan 920.
