Description

Technical Field

[0001] This application relates to the field of kitchen equipment technology, and in particular to an air duct structure and an integrated stove structure. Background Technology

[0002] An integrated cooktop is a kitchen appliance that combines multiple functions such as a range hood, gas stove, disinfection cabinet, and storage cabinet. It is also known in the industry as an eco-friendly cooktop or integrated eco-friendly cooktop. Integrated cooktops offer advantages such as space saving, excellent fume extraction, energy efficiency, and environmental friendliness.

[0003] If the cooktop is combined with other cooking appliances (such as steam ovens, ovens, steam-grill combos, etc.) to form an integrated cooktop structure, for example... Figure 1 The diagram shows the front structure of the integrated cooktop, where cooking equipment can be installed below the cooktop. To facilitate easier and quicker assembly and disassembly of the cooktop and other cooking equipment, the installation and maintenance access is located at the rear of the cooktop. Figure 2 This is a schematic diagram of an integrated stove structure, such as... Figure 2 As shown, to enhance the aesthetics of the stove, the water collection box and air duct cover are located on the left side of the bottom shell. Considering the temperature rise of the fan, the cooling fan is positioned in the middle of the bottom shell (the direction indicated in the diagram is not specific and is only for illustrative purposes). After the cooling fan outlet is connected to the air duct cover, with the outlet size remaining constant, due to the influence of airflow and velocity, most of the heat will be exhausted through the channel formed by the connection between the cooling fan outlet and the air duct cover. A small amount of heat may escape through the connection point further away from the cooling fan outlet. In other words, the air from the cooling fan cannot be dispersedly exhausted through the air duct cover because the airflow near the cooling fan outlet is larger and faster, carrying away more heat. Therefore, the stove near this location may be in a high-temperature environment with rapid airflow around the flame for a long time, which will affect the stove's thermal efficiency over time. Summary of the Invention

[0004] This application provides an air duct structure and an integrated stove structure. In this air duct structure, a spatial partition is provided to form multiple heat dissipation channels. By adjusting the relative size of the inlet cross-section of each heat dissipation channel and the relative size of the inlet cross-section of the heat dissipation channel corresponding to the air inlet, the hot air blown out by the cooling fan can be dispersed and discharged from the multiple heat dissipation channels, thereby reducing the impact of hot air on the stove's thermal efficiency.

[0011] In one optional embodiment, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is a first type, the drainage structure of each space partition (2) is a first drainage structure, and the length of the space partition near the air inlet (11) is greater than the length of the space partition away from the air inlet (11).

[0012] The first type represents that each of the multiple space partitions (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged in parallel.

[0013] The first drainage structure characterizes the drainage surface of each spatial partition (2) as a plane.

[0014] In one optional embodiment, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is a second type, and the drainage structure of each space partition (2) is a first drainage structure;

[0015] The second type represents that each of the multiple space partitions (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged radially.

[0016] The first drainage structure characterizes the drainage surface of each spatial partition (2) as a plane.

[0017] In one optional embodiment, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is the second type, and the drainage structure of the multiple space partitions (2) is the second drainage structure;

[0018] The second type represents that each of the multiple space partitions (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged radially.

[0019] The second drainage structure characterizes the drainage structure of multiple spatial partitions (2) as a curved drainage structure or a folded drainage structure.

[0020] In one alternative embodiment, when the lengths of the multiple space partitions (2) are the same, the curvature of the flow-guiding structure of the space partition closer to the air inlet (11) is greater than that of the space partition farther from the air inlet (11).

[0021] In an alternative embodiment, the ventilation hood structure (1) is disposed on the equipment equipped with the air duct structure; the ventilation hood structure includes a side panel (13) and a cover plate (14);

[0026] The air duct structure and integrated stove structure provided in this application have the following technical effects:

[0027] This application proposes a duct structure and an integrated stove structure. The duct structure includes a ventilation hood structure and at least one space partition. The ventilation hood structure includes an air inlet and an air outlet. The air inlet is connected to the air outlet channel of a cooling fan. At least one space partition is disposed within the ventilation hood structure to divide the space within the ventilation hood structure into multiple horizontally parallel heat dissipation channels. Among the multiple heat dissipation channels, the channel inlet cross-section of the heat dissipation channel closer to the air inlet is smaller than the channel inlet cross-section of the heat dissipation channel farther from the air inlet, and the channel inlet cross-section of the heat dissipation channel corresponding to the air inlet is smaller than the cross-section of the air inlet. The embodiments of this application form multiple heat dissipation channels by setting spatial partitions in the air duct structure. By adjusting the relative size of the channel inlet cross-section of each heat dissipation channel and the relative size of the channel inlet cross-section and the air inlet cross-section of the heat dissipation channel corresponding to the air inlet, the hot air blown out by the cooling fan can be dispersed and discharged from multiple heat dissipation channels. Because the hot air is dispersed, the air volume of the hot air is reduced, the air velocity is reduced, the temperature around the stove is not too high, and the air circulation speed around the stove flame is reduced, thereby reducing the impact of hot air on the thermal efficiency of the stove.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0043] Please see Figure 3 , Figure 3This is a top view schematic diagram of a duct structure provided in an embodiment of this application. The duct structure includes a ventilation hood structure (1) and at least one space partition (2). The ventilation hood structure (1) may include an air inlet (11) and an air outlet (12). The air inlet (11) is connected to the air outlet channel (31) of the cooling fan (3). At least one space partition (2) is disposed inside the ventilation hood structure (1) to divide the space inside the ventilation hood structure (1) into multiple horizontally parallel heat dissipation channels (4). Among the multiple heat dissipation channels (4), the channel inlet cross section of the heat dissipation channel near the air inlet (11) is smaller than the channel inlet cross section of the heat dissipation channel away from the air inlet (11), and the channel inlet cross section of the heat dissipation channel corresponding to the air inlet (11) is smaller than the cross section of the air inlet (11).

[0044] By setting spatial partitions in the air duct structure to form multiple heat dissipation channels, and by adjusting the relative size of the channel inlet cross-section of each heat dissipation channel and the relative size of the channel inlet cross-section and the air inlet cross-section of the heat dissipation channel corresponding to the air inlet, the hot air blown out by the cooling fan can be dispersed and discharged from multiple heat dissipation channels. Because the hot air is dispersed, the air volume of the hot air is reduced, the wind speed is reduced, the temperature around the stove is not too high, and the air circulation speed around the stove flame is reduced, thereby reducing the impact of hot air on the thermal efficiency of the stove.

[0045] In the embodiments of this application, Figure 4 This is a schematic diagram of a duct structure provided in an embodiment of this application, such as... Figure 4 As shown, the entire ventilation hood structure (1) can be installed on equipment equipped with an air duct structure. The ventilation hood structure (1) can be formed by side panels (13) and cover plates (14). The air inlet (11) and air outlet (12) are opened on the side panels (13). The cover plate can enclose the space formed by the side panels.

[0046] Optionally, the cover plate and side panels can be connected by screws or assembled together by welding. The cover plate and side panels can be made of aluminum alloy, stainless steel, or galvanized steel. Air inlets and outlets can be provided on the side panels, which can be located on two opposite sides of the side panels. The air inlets are connected to the exhaust duct of the cooling fan, allowing hot air to pass through the exhaust duct and air inlet of the cooling fan before being exhausted from the exhaust outlet.

[0047] By installing a cover plate and side panels, and placing the air inlet and outlet on the side panels respectively, hot air can be guided from the air inlet to the air outlet and discharged smoothly.

[0048] In one alternative embodiment, Figure 5 This is a schematic diagram illustrating the vertical distance between the air inlet and outlet of a duct structure provided in an embodiment of this application. Figure 5 As shown, the vertical distance H between the air outlet (12) and the air inlet (11) is less than the first preset distance. In the ventilation hood structure (1), there is at least one space partition (2) that divides the space inside the ventilation hood structure (1) into multiple horizontally parallel heat dissipation channels (4).

[0049] The air inlet shown in the figure is located on the right side of the ventilation hood structure. At the same time, the area of ​​the air outlet is larger than that of the air inlet. If the vertical distance H between the air outlet and the air inlet is relatively small, the size of the air inlet remains unchanged, and the air velocity and volume of the air discharged from the cooling fan outlet channel are relatively high, most of the hot air will be directly discharged vertically from the air inlet to the air outlet, that is, discharged from the air outlet on the right side, while a small amount of air will be dispersed to the air outlet on the left side (the direction marked in the figure is not limited and is only for illustrative purposes).

[0050] Over time, the air exhaust on the right side will have higher heat and faster air speed. If a stove is located near the right-side air outlet, the air around the stove flame will move faster due to the hot air, and the temperature around the stove will remain at a high level for a long time, which will affect the stove's thermal efficiency.

[0051] At this point, in order to divert most of the hot air discharged from the right-side air outlet and disperse it relatively far from the air duct structure, at least one spatial partition can be installed in the ventilation hood structure. This spatial partition can divide the space within the ventilation hood structure into multiple horizontally parallel heat dissipation channels. Simultaneously, it ensures that among the multiple heat dissipation channels, the inlet cross-section of the heat dissipation channel closer to the air inlet is smaller than the inlet cross-section of the heat dissipation channel farther from the air inlet, and the inlet cross-section of the heat dissipation channel corresponding to the air inlet is smaller than the cross-section of the air inlet.

[0052] This design can divert the airflow from the air inlet to the right-side air outlet to the left, thus increasing the air outlet area. At this time, the air volume is dispersed, the wind speed can be reduced, and the air flow speed around the stove flame will not be too fast, reducing the impact on the stove's thermal efficiency.

[0053] In one possible scenario, if the vertical distance between the air inlet and outlet is large enough, and the area of ​​the air inlet is smaller than the area of ​​the air outlet, then when high-speed hot air flows in from the air inlet, the hot air can diffuse and flow in the space between the air inlet and outlet, and then be discharged from the larger air outlet. In this case, there is no problem with the inability to relatively disperse and discharge the hot air. If a space partition is installed in the ventilation hood structure at this time, the airflow guiding effect of the space partition will not be very significant.

[0054] Based on the above analysis, if the vertical distance H between the air outlet and the air inlet is relatively small, the size of the air inlet remains constant, and the air velocity and volume discharged from the cooling fan's exhaust channel are relatively high, the air in the cooling fan cannot be relatively dispersed and discharged through the ventilation hood structure. This problem can be solved by installing spatial partitions in the ventilation hood structure and ensuring the relationship between the inlet cross-sections of the air inlet and the cooling channel, as well as the setting of the inlet cross-sections of each cooling channel.

[0055] If the vertical distance between the air outlet and the air inlet is relatively large, and the air velocity and volume of the air discharged from the air outlet of the cooling fan are relatively high, the hot air can also be discharged relatively dispersedly from each air outlet of the entire ventilation hood structure. Therefore, there is no problem that "the air in the cooling fan cannot be discharged relatively dispersedly through the ventilation hood structure". Thus, there is no need to install space partitions in the ventilation hood structure.

[0056] The aforementioned first preset distance is the critical distance for achieving relatively dispersed exhaust of hot air from each outlet of the entire ventilation hood structure. If the vertical distance between the air inlet and outlet is greater than the first preset distance, there is no need to install a space partition. If the vertical distance between the air inlet and outlet is less than the first preset distance, installing a space partition can help solve the problem of hot air not being able to be relatively dispersedly exhausted from the ventilation hood structure. Therefore, the first preset distance is a prerequisite for installing a space partition.

[0057] Optionally, the first preset distance can be determined based on a combination of factors, including the maximum wind speed and maximum air volume of the hot air blown out by the cooling fan, the size of the ventilation hood structure, and the space of the equipment on which the ventilation hood structure is installed. In one optional embodiment, the range of the first preset distance may include [5cm, 10cm], or the first preset distance may be [2cm, 20cm], for example, the first preset distance may be 8cm or 15cm, where cm represents centimeters as a unit of length.

[0058] The vertical distance H between the air outlet and the air inlet is set to be less than a first preset distance. This first preset distance is the critical distance for achieving relatively dispersed hot air discharge from each air outlet of the entire ventilation hood structure. If the vertical distance between the air inlet and the air outlet is greater than the first preset distance, then even without a space partition, the hot air can still be discharged from the ventilation hood structure in a relatively dispersed manner. In this case, the space partition loses its function of diverting the airflow. Therefore, it is essential to ensure that the vertical distance between the air outlet and the air inlet is less than the first preset distance; only under these conditions will the space partition have the effect of diverting the hot airflow.

[0059] In one alternative embodiment, combined with Figure 3 and Figure 4Continuing the explanation, at least one space partition can be installed within the space formed by the ventilation hood structure. This space partition can divide the space into multiple horizontally parallel heat dissipation channels. Optionally, the space partition can be made of aluminum alloy, stainless steel, or galvanized steel plate. The space partition can be welded to the inside of the ventilation hood structure cover plate without contacting the side panels, or it can be bonded to the inside of the cover plate, forming a certain ventilation space with the side panels.

[0060] Figure 6 This is a simplified schematic diagram of the channel inlet cross-section and air inlet cross-section of a heat dissipation channel provided in an embodiment of this application, as shown below. Figure 6 As shown, among the multiple heat dissipation channels (4) formed, the channel inlet cross-section h1 of the heat dissipation channel near the air inlet (11) is smaller than the channel inlet cross-section h2 of the heat dissipation channel away from the air inlet (11), and the channel inlet cross-section h1 of the heat dissipation channel corresponding to the air inlet (11) is smaller than the cross-section h3 of the air inlet (11). When the vertical distance H between the air inlet (11) and the air outlet (12) is less than the first preset distance, the hot air in the cooling fan reaches the ventilation hood structure through the air inlet, because the channel inlet cross-section h1 of the heat dissipation channel corresponding to the air inlet is smaller than the cross-section h3 of the air inlet.

[0061] In this way, the airflow through the heat dissipation channel corresponding to the air inlet will be less than the total airflow entering the air inlet, and the hot air will be dispersed and discharged from other heat dissipation channels. In order to reduce the airflow discharged from the heat dissipation channel near the air inlet and increase the airflow discharged from the heat dissipation channel far from the air inlet, the inlet cross-section h1 of the heat dissipation channel near the air inlet can be set to be smaller than the inlet cross-section h2 of the heat dissipation channel far from the air inlet. This ensures that the hot air in the cooling fan can be discharged from the ventilation hood structure in a relatively dispersed manner.

[0062] In one alternative embodiment, combined with Figure 5 Further explanation: when at least one space partition (2) includes multiple space partitions, the length of the space partition corresponding to the channel inlet section and the air inlet (11) of each of the multiple heat dissipation channels (4), the air diversion structure and the setting position within the ventilation hood structure (1) are related.

[0063] Specifically, the inlet cross-section of each of the multiple heat dissipation channels can be altered by adjusting at least one of three factors: the length of the space partition corresponding to the air inlet, the airflow structure, and the position of the space partition within the ventilation hood structure. A smaller inlet cross-section results in a smaller volume of hot air flowing into the heat dissipation channel, while a larger inlet cross-section results in a relatively larger volume of hot air. Therefore, the total amount of hot air entering from the air inlet can be diverted, allowing it to exit through different heat dissipation channels, thus reducing the velocity and flow rate of the hot air. The reduced exhaust velocity and dispersed flow rate prevent excessively fast airflow around the stove flame and excessively high temperatures around the stove, thus minimizing the impact on the stove's thermal efficiency.

[0064] In one optional embodiment, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is a first type, and the air diversion structure of each space partition (2) is a first air diversion structure. The length of the space partition near the air inlet (11) is greater than the length of the space partition away from the air inlet (11). The first type indicates that each of the multiple space partitions (2) is located at the same starting position at the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged in parallel. The first air diversion structure indicates that the air diversion surface of each space partition (2) is a plane.

[0065] Specifically, Figure 7 This is a top view schematic diagram of a space partition component provided in an embodiment of this application. Figure 1 ,like Figure 7 As shown, when the arrangement type of multiple space partitions (2) in the ventilation hood structure (1) is the first type, that is, each space partition in the multiple space partitions (2) is located at the same starting position of the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged in parallel, and the air guiding surface of each space partition (2) is a plane, the length of the space partition near the air inlet (11) is greater than the length of the space partition away from the air inlet (11).

[0066] This is because each of the multiple space partitions has the same starting position and the same airflow structure. By adjusting the length of the space partitions, the size of the inlet cross-section of the heat dissipation channel can be adjusted. For example, Figure 7The length of the partition near the air inlet is greater than the length of the partition further away from the air inlet. When hot air flows into the air inlet, the longer partition near the inlet can more quickly block and disperse the hot air, effectively diverting it. This disperses the total airflow into different heat dissipation channels, reducing air velocity and flow rate. The exhaust air velocity decreases, and the flow rate becomes more dispersed. The airflow around the stove flame is not too fast, and the temperature around the stove is not too high, thus minimizing the impact on the stove's thermal efficiency.

[0067] In one optional embodiment, the arrangement of the multiple space partitions (2) in the ventilation hood structure (1) is of the second type, and the airflow structure of each space partition (2) is of the first type. The second type indicates that each of the multiple space partitions (2) is located at the same starting position at the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged radially. The first airflow structure indicates that the airflow surface of each space partition (2) is planar.

[0068] Specifically, Figure 8 This is a top view schematic diagram of a space partition component provided in an embodiment of this application. Figure 2 ,like Figure 8 As shown, when the arrangement type of multiple space partitions (2) in the ventilation hood structure (1) is the second type, that is, each space partition (2) in the ventilation hood structure (1) has the same starting position at the air outlet (12), and the multiple space partitions (2) are arranged radially. The airflow guiding surface of each space partition (2) is a plane. At this time, the length of the space partition near the air inlet (11) can be greater than the length of the space partition far from the air inlet (11), or it can be equal to or less than the length of the space partition far from the air inlet.

[0069] This is because, in a radial arrangement, when each spatial partition is positioned at the same starting point of the air outlet within the ventilation hood structure, this arrangement itself can adjust the size of the inlet cross-section of each heat dissipation channel. Therefore, changing the length has little impact on the size of the inlet cross-section of the heat dissipation channel. By setting the positional structure of the radially arranged spatial partitions, the inlet cross-section of the heat dissipation channel near the air inlet is smaller than that of the heat dissipation channel farther from the air inlet. This ensures that the total airflow into the air inlet is distributed across multiple heat dissipation channels, achieving a certain degree of airflow diversion.

[0070] In one optional embodiment, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is a second type, and the airflow diversion structure of the multiple space partitions (2) is a second airflow diversion structure. The second type indicates that each of the multiple space partitions (2) is located at the same starting position at the air outlet (12) in the ventilation hood structure (1), and the multiple space partitions (2) are arranged radially. The second airflow diversion structure indicates that the airflow diversion structure of the multiple space partitions (2) is a curved surface airflow diversion structure or a folded angle airflow diversion structure.

[0071] Specifically, when the arrangement type of multiple space partitions in the ventilation hood structure is the second type, that is, each space partition in the ventilation hood structure is located at the same starting position of the air outlet, and the multiple space partitions are arranged radially, the air diversion structure of each space partition can be a curved air diversion structure or a folded air diversion structure.

[0072] When hot air encounters the space partition at the air inlet, if the space partition is an angled or curved flow-guiding structure, the airflow direction is changed due to the obstruction of the space partition's flow surface. The air will flow along the flow surface of the space partition and enter different heat dissipation channels, thus dispersing the air volume and reducing the air velocity. The exhaust air velocity will decrease, the flow rate will be relatively dispersed, the airflow speed around the stove flame will not be too fast, the temperature around the stove will not be too high, and the stove's thermal efficiency will not be significantly affected.

[0073] In one alternative embodiment, when the lengths of the multiple space partitions (2) are the same, the curvature of the flow-guiding structure of the space partition closer to the air inlet (11) is greater than that of the space partition farther from the air inlet (11).

[0074] Specifically, Figure 9 This is a top view schematic diagram of a space partition component provided in an embodiment of this application. Figure 3 ,like Figure 9 As shown, the arrangement type of the multiple space partitions (2) in the ventilation hood structure (1) is the second type, that is, each space partition (2) in the ventilation hood structure (1) has the same starting position at the air outlet (12), and the multiple space partitions (2) are arranged radially. When the air diversion structure of the multiple space partitions (2) is a folded air diversion structure, each space partition (2) in the multiple space partitions (2) may include a first partition (21) and a second partition (22). The fold angle (23) between the first partition (21) and the second partition (22) ranges from [90°, 180°], and the fold angle of the space partition near the air inlet (11) is smaller than the fold angle of the space partition away from the air inlet (11).

[0075] Optionally, the connection between the first and second partition components can be welding or adhesive bonding. The connection between the first and second partition components can form an angle, which can range from [90°, 180°], with the angle decreasing as the partition component approaches the air inlet. This allows adjustment of the inlet cross-section of the heat dissipation channels by adjusting the angle, ensuring that the inlet cross-section of the heat dissipation channels closer to the air inlet is smaller than that of the channels farther from the air inlet. This disperses the total airflow into the air inlet into multiple heat dissipation channels, achieving a certain degree of airflow distribution.

[0076] In one alternative embodiment, Figure 10 This is a top view schematic diagram of a space partition component provided in an embodiment of this application. Figure 4 ,like Figure 10 As shown, the arrangement of multiple space partitions (2) in the ventilation hood structure (1) is of type two, that is, each space partition (2) in the ventilation hood structure (1) has the same starting position at the air outlet (12), and the multiple space partitions (2) are arranged radially. When the air diversion structure of the multiple space partitions (2) is a curved air diversion structure, the curvature of the space partitions (2) closer to the air inlet (11) is greater than the curvature of the space partitions (2) farther from the air inlet (11).

[0077] This allows for adjustment of the inlet cross-section of the heat dissipation channels by modifying the curvature of the space partition. This ensures that the inlet cross-section of the heat dissipation channels closer to the air inlet is smaller than that of the channels farther from the air inlet, thus distributing the total airflow into multiple channels and achieving a certain degree of air diversion. The exhaust air velocity will decrease, the flow rate will be more dispersed, the airflow speed around the stove flame will not be too fast, and the temperature around the stove will not be too high, thus minimizing the impact on the stove's thermal efficiency.

[0078] On the other hand, embodiments of this application provide an integrated stove structure, including the air duct structure as described above.

[0079] In one alternative embodiment, Figure 11 This is a schematic diagram of an integrated stove structure including a cooling hood structure and an air duct structure provided in an embodiment of this application, as shown below. Figure 11 As shown, the integrated stove structure may also include a cooling hood structure (5) detachably connected to the air duct structure, and the cooling hood structure (5) has a side plate (51) on the side facing the air outlet (12). The side plate (51) includes at least one cooling inlet (52) communicating with the air outlet (12).

[0080] Specifically, Figure 12 This is a detailed internal schematic diagram of a cooling shroud structure provided in an embodiment of this application, as shown below. Figure 12 As shown in the image, the cooling hood structure (5) is connected to the air duct structure. The cooling hood structure (5) includes a side plate (51). At least one cooling inlet (52) can be opened on the side plate, and the cooling inlet (52) can be connected to the air outlet (12) of the air duct structure. The cooling hood structure can be detachably connected to the air duct structure, or it can be installed on equipment equipped with an air duct structure (such as an integrated stove structure). At the same time, the cooling hood structure (5) is correspondingly set with the air outlet (12) of the air duct structure.

[0081] Optionally, the cooling shroud structure (5) can be connected to the edge of the air duct structure by screws, or it can be connected to the equipment equipped with the air duct structure by screws, while contacting the air outlet (12) of the air duct structure. A side plate (51) is provided on the side of the cooling shroud structure (5) facing the air outlet (12), and the material of the side plate (51) can be metal. The side plate (51) may include one or more cooling inlets (52), which are used to connect to the air outlet (12). Hot air flowing out of the air outlet enters the cooling shroud structure through the cooling inlet. The cooling shroud structure can cool and reduce the temperature of the hot air, preventing the hot air from accumulating a large amount of heat near the stove, so that the stove is in a high-temperature environment for a long time, which will affect the heat effect of the stove.

[0082] When there is only one cooling inlet on the side panel, a thicker side panel is required. This is because with only one cooling inlet, the airflow is concentrated at that inlet, resulting in a higher airflow and velocity compared to other parts of the side panel. This creates a relatively concentrated pressure around the cooling inlet, making the side panel more prone to deformation under pressure. Therefore, increasing the thickness of the side panel can reduce the likelihood of deformation.

[0083] Optionally, when there are multiple cooling inlets on the side panel, these inlets can be arranged relatively evenly on the side, and the air in the air outlet of the duct structure can be further diverted at the cooling inlets. Simultaneously, the hot air entering the cooling shroud structure can be cooled, ensuring that the blown air is relatively dispersed and not too hot. This relatively dispersed airflow has little impact on the airflow speed around the stove flame, and the temperature around the stove will not be excessively high. Therefore, the impact of cooling and diverted airflow on the stove's thermal efficiency is reduced.

[0084] By incorporating a cooling shroud structure that is detachably connected to the air duct structure, the air exhausted from the outlet can be further diverted, while simultaneously cooling the hot air. This results in a more dispersed airflow with a lower temperature, preventing increased airflow around the stove flame and avoiding the accumulation of excessive heat around the stove. This reduces the impact of the exhaust air from the cooling fan on the stove's thermal efficiency.

[0085] This application proposes a duct structure and an integrated stove structure. The duct structure includes a ventilation hood structure and at least one space partition. The ventilation hood structure includes an air inlet and an air outlet. The air inlet is connected to the air outlet channel of a cooling fan. At least one space partition is disposed within the ventilation hood structure to divide the space within the ventilation hood structure into multiple horizontally parallel heat dissipation channels. Among the multiple heat dissipation channels, the channel inlet cross-section of the heat dissipation channel closer to the air inlet is smaller than the channel inlet cross-section of the heat dissipation channel farther from the air inlet, and the channel inlet cross-section of the heat dissipation channel corresponding to the air inlet is smaller than the cross-section of the air inlet.

[0086] The embodiments of this application form multiple heat dissipation channels by setting spatial partitions in the air duct structure. By adjusting the relative size of the channel inlet cross-section of each heat dissipation channel and the relative size of the channel inlet cross-section and the air inlet cross-section of the heat dissipation channel corresponding to the air inlet, the hot air blown out by the cooling fan can be dispersed and discharged from multiple heat dissipation channels. Because the hot air is dispersed, the air volume of the hot air is reduced, the air velocity is reduced, the temperature around the stove is not too high, and the air circulation speed around the stove flame is reduced, thereby reducing the impact of hot air on the thermal efficiency of the stove.
