Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to an integrated cooking device. Background Technology

[0002] Integrated cooking appliances typically combine the cooktop and steam / bake micro-components into a single unit, offering multiple cooking functions such as cooktop cooking, steaming, baking, and microwave heating. Compared to single-function cooking appliances, integrated cooking appliances have a more compact internal structure, with limited space for the heat source, electrical components, and exhaust system, making heat dissipation a more prominent issue.

[0003] In existing integrated cooking equipment, the cooktop assembly is typically located above the steam-grill micro-assembly. The steam-grill micro-assembly forms a cooking cavity, and electrical components such as a power board, water pump, and solenoid valve may also be located above it. The cooktop assembly typically houses electrical components such as the control panel, valve body, and igniter. When the equipment is operating, the heat and steam generated in the cooking cavity, as well as the heat generated by the cooktop, raise the temperature of the surrounding space containing these electrical components.

[0004] Existing heat dissipation solutions typically involve using cooling fans for localized heat-generating components or guiding hot air from the cooktop's interior to the exhaust vents via an internal fan. While these solutions can reduce the temperature rise of localized components to some extent, they struggle to expel hot air from the space above the steaming / grilling micro-components, causing it to stagnate in the area between the cooktop components and the micro-components. Adding a separate exhaust channel or outlet for this electrical component mounting space would increase the overall structural complexity, occupy limited installation space, and negatively impact assembly and aesthetics.

[0005] In addition, the electrical components inside the cooktop assembly and the electrical components above the steaming and baking micro-assemblies are located in different areas. If their heat dissipation air paths are independent of each other, it is easy to cause problems such as an increase in the number of fans, repeated arrangement of air ducts, and dispersed exhaust paths, which is not conducive to forming a continuous and efficient heat dissipation path in a compact space. Summary of the Invention

[0006] Therefore, it is necessary to provide an integrated cooking device that can unify the hot air from the electrical component installation space above the steaming and baking micro-components and the hot air from the internal space of the stove without significantly increasing the complexity of the overall structure.

[0007] This application provides an integrated cooking device, including a cooktop assembly, a lower cooking assembly, a first cooling fan, and a second cooling fan. The cooktop assembly has an internal cooktop space and an exhaust port communicating with the outside. The lower cooking assembly is disposed below the cooktop assembly and includes an upper mounting plate and a top plate disposed above the upper mounting plate. An electrical component mounting space is formed between the upper mounting plate and the top plate, and the partition area between the top plate and the cooktop assembly is a middle partition layer. The first cooling fan has a primary air inlet and a primary air outlet. The primary air inlet communicates with the electrical component mounting space, and the primary air outlet communicates with the middle partition layer. The second cooling fan has a partition layer air inlet, a cooktop air inlet, and a converging air outlet. The partition layer air inlet communicates with the middle partition layer, the cooktop air inlet communicates with the internal cooktop space, and the converging air outlet communicates with the exhaust port.

[0008] This application establishes an upper mounting plate and a top plate within the lower cooking assembly, creating an electrical component mounting space between the upper mounting plate and the top plate, and a middle partition between the top plate and the cooktop assembly. A first cooling fan draws hot air from the electrical component mounting space into the middle partition, while a second cooling fan draws hot air from the middle partition through the partition's air inlet and from the cooktop's internal space through the cooktop's air inlet. This allows the hot air from the electrical component mounting space and the cooktop's internal space to converge at the second cooling fan and then be discharged through the exhaust port. Therefore, on the one hand, the middle partition serves as an airflow transition space, connecting the electrical component mounting space above the lower cooking assembly to the cooktop assembly's exhaust path, reducing hot air stagnation within the electrical component mounting space; on the other hand, it allows the electrical component mounting space and the cooktop's internal space to share the second cooling fan and exhaust port for heat dissipation, avoiding the problems of increased fan count, redundant ductwork, and increased overall structural complexity caused by separate exhaust paths for different areas.

[0009] In one embodiment, the first cooling fan is connected to the top plate, and the top plate is provided with a ventilation opening corresponding to the first cooling fan. The ventilation opening connects the electrical component installation space and the intermediate partition layer.

[0010] This configuration allows the ventilation openings to provide a channel for the exhaust air of the first cooling fan to pass through the top plate, creating a clear airflow connection between the electrical component installation space and the intermediate partition layer, which helps reduce the retention of hot air below the top plate.

[0011] In one embodiment, the first cooling fan is located within the electrical component mounting space, and the ventilation opening is aligned with and connected to the primary air outlet.

[0012] This configuration, with the primary air outlet aligned with the ventilation opening, shortens the path of the primary cooling fan to the intermediate partition, reduces airflow diffusion losses near the top plate, and improves the efficiency of heat dissipation from the electrical component installation space to the intermediate partition.

[0013] In one embodiment, the top plate is provided with a boss located around the ventilation opening and protruding toward the intermediate spacer.

[0014] This design allows the boss to raise the structural height around the ventilation opening, reducing the risk of liquid entering the electrical component installation space through the ventilation opening when there is a small amount of liquid in the intermediate partition. At the same time, it provides an installation and reinforcement base for the first cooling fan or the structure around the ventilation opening.

[0015] In one embodiment, the cooktop assembly has an exhaust box and a heat dissipation duct is constructed inside the cooktop assembly. The heat dissipation duct is disposed between the confluence air outlet and the exhaust port, and the confluence air outlet, the heat dissipation duct, the exhaust box and the exhaust port are sequentially connected.

[0016] With this configuration, the hot air discharged from the second cooling fan can enter the exhaust box through the cooling duct and then be discharged to the outside through the exhaust port. The cooling duct and the exhaust box together define the exhaust path, which is conducive to organizing a stable external exhaust flow within the cooktop components.

[0017] In one embodiment, the height of the heat dissipation duct gradually decreases and its width gradually increases from one end near the second heat dissipation fan to one end near the exhaust box.

[0018] This configuration, by gradually increasing the width to compensate for the change in flow area caused by the decrease in height, allows the airflow to maintain a relatively stable flow cross section as it flows from the second cooling fan to the exhaust box, reducing sudden changes in local wind resistance, lowering airflow noise and flow loss, and facilitating the connection between the cooling duct and the exhaust box.

[0019] In one embodiment, the top of the exhaust box is open and connected to the exhaust port, the exhaust box has a heat dissipation air inlet located on the side wall of the exhaust box, and the heat dissipation air duct is connected to the heat dissipation air inlet.

[0020] With this configuration, hot air in the heat dissipation duct can enter the exhaust box from the side wall of the exhaust box and be discharged from the top of the exhaust box to the exhaust port. The airflow direction is smoothly connected with the exhaust direction, which helps to reduce the local resistance inside the exhaust box.

[0021] In one embodiment, the lower cooking assembly further includes an inner pot located below the upper mounting plate, the inner pot being connected to an inner pot exhaust pipe, the inner pot exhaust pipe being in communication with the exhaust box.

[0022] With this configuration, the hot exhaust gas or steam generated by the inner liner can enter the exhaust box through the inner liner exhaust pipe, allowing the inner liner exhaust and the heat dissipation exhaust to share the same exhaust box and exhaust port, which helps to reduce the number of separate exhaust structures and improve the overall structural compactness.

[0023] In one embodiment, the top of the exhaust box is open and connected to the exhaust port, the exhaust box has an inner liner air inlet, the inner liner air inlet is located on the bottom surface of the exhaust box, and the inner liner exhaust pipe is connected to the inner liner air inlet.

[0024] With this configuration, the inner liner exhaust pipe can be connected to the exhaust box from the bottom upwards, adapting to the arrangement of the inner liner below the upper mounting plate, and allowing the exhaust from the inner liner and the cooling airflow from the heat dissipation air inlet to enter the exhaust box from different positions.

[0025] In one embodiment, the integrated cooking device further includes a heat dissipation component, which includes a first fan, a first air duct, a second fan, and a second air duct respectively connected to the upper mounting plate. The first air duct is connected to the air outlet side of the first fan and the air intake side of the second fan, and the second air duct is connected to the air outlet side of the second fan.

[0026] With this configuration, the heat dissipation components can form an auxiliary heat dissipation path consisting of a first fan, a first air duct, a second fan, and a second air duct connected in sequence, providing zoned heat dissipation for other heat-generating components near the upper mounting plate, and complementing the first and second heat dissipation fans.

[0027] In one embodiment, the first cooling fan is located between the first air duct and the second air duct, and at one end of the air outlet side of the second air duct, and the primary air inlet is connected to the space outside the first air duct and the second air duct.

[0028] With this configuration, the first cooling fan can draw in hot air from areas outside the first and second air ducts, especially in spaces that are difficult to cover by the auxiliary cooling path, thereby enhancing the overall heat dissipation effect within the electrical component installation space.

[0029] In one embodiment, the first air duct includes an upstream air duct section and a downstream air duct section connected in sequence. The upstream air duct section is connected to the air outlet side of the first fan and is located above the upper mounting plate. The downstream air duct section is connected to the air inlet side of the second fan and is located below the upper mounting plate. The portion of the heat dissipation assembly other than the downstream air duct section is located above the upper mounting plate.

[0030] With this configuration, the first air duct can be arranged across the upper and lower sides of the upper mounting plate, directing the airflow output by the first fan to the air inlet of the second fan; except for the downstream air duct section, the heat dissipation components are mainly located above the upper mounting plate, which is conducive to the centralized arrangement of the heat dissipation structure above the upper mounting plate.

[0031] In one embodiment, the heat dissipation assembly includes an air guide structure that participates in defining a second air duct, the air guide structure defining a plurality of air guide layers, the air guide structure having a lateral air outlet communicating with at least a portion of the air guide layers, the lateral air outlet being used to exhaust at least a portion of the airflow within the corresponding air guide layer outside the second air duct, the lateral air outlet being directed toward the electrical component mounting space located between the first air duct and the second air duct.

[0032] With this configuration, the air guide structure can divide the second air duct into multiple air guide layers, and guide the airflow in at least part of the air guide layers to the electrical component installation space through the side air outlets, thereby achieving directional heat dissipation for local electrical control components.

[0033] In one embodiment, the air guiding structure includes a support plate that defines the second air duct and divides the second air duct into a first air guiding layer above the support plate and a lower air guiding space below the support plate; the air guiding structure also includes a first guide plate disposed at the bottom of the lower air guiding space and extending toward the support plate, wherein the portion of the lower air guiding space between the top of the first guide plate and the support plate forms a second air guiding layer, and the portion below the top of the first guide plate forms a third air guiding layer.

[0034] With this configuration, the support plate and the first guide plate together divide the second air duct into a first guide layer, a second guide layer, and a third guide layer, so that the airflow in the second air duct can be distributed according to different height layers, which is beneficial for the layered heat dissipation of electrical components in different locations.

[0035] In one embodiment, the lateral air outlet is located upstream of the first guide plate and communicates with the third air guide layer; the first guide plate is located on the airflow path within the third air guide layer and blocks at least a portion of the flow cross-section of the third air guide layer.

[0036] With this configuration, the first guide vane can change the flow path and local flow cross-section of the airflow in the third guide layer, making it easier for some of the airflow in the third guide layer to be discharged through the lateral air outlet, thereby improving the reliability of lateral fixed-point air supply.

[0051] Please see Figures 1 to 2 This application provides an integrated cooking device 100, which can be a stove-steam-oven-microwave all-in-one appliance, or a steam oven, microwave-steam oven, steamer, oven, microwave oven, or other cooking device with an inner cavity 124 and electronic control components. This embodiment uses a stove-steam-oven-microwave all-in-one appliance as an example for illustration, but it should not be construed as a limitation on the type of cooking device.

[0052] Combination Figure 1 and Figure 2 As shown, the integrated cooking appliance 100 includes a cooktop assembly 110, a lower cooking assembly 120, a first cooling fan 140, and a second cooling fan 150. Figure 2 and Figure 3 As shown, the cooktop assembly 110 has an internal cooktop space 111 and an exhaust port 112 that communicates with the outside. The internal cooktop space 111 can accommodate components such as an operation control panel, valve body, and igniter.

[0053] In one embodiment, the cooktop assembly 110 further includes a panel 113, and an exhaust port 112 is provided on the panel 113. Specifically, the panel 113 is located on the upper side of the cooktop assembly 110, and the exhaust port 112 is provided near the edge of the panel 113 so that hot air in the exhaust box 114 can be discharged to the outside of the integrated cooking appliance 100 through the exhaust port 112.

[0054] The lower cooking component 120 is located below the cooktop component 110. The lower cooking component 120 can be a steaming and baking micro-component or a cooking component with at least one of the functions of steaming, baking, and microwave heating.

[0055] like Figure 1 and Figure 2 As shown, the lower cooking assembly 120 includes an upper mounting plate 121 and a top plate 122 disposed above the upper mounting plate 121. An electrical component mounting space 123 is formed between the upper mounting plate 121 and the top plate 122, and components such as a power supply board, water pump, and solenoid valve can be arranged in the electrical component mounting space 123. The partition area between the top plate 122 and the cooktop assembly 110 is a middle partition layer 130.

[0056] The intermediate partition 130 can be used to form a thermal isolation space, structural installation space or airflow transition space between the upper and lower cooking modules to reduce the impact of the heat generated by the lower cooking component 120 during operation on the cooktop component 110, and to provide space for the arrangement of the cooktop chassis, pipes, wiring harnesses, exhaust structure or heat dissipation structure.

[0057] From bottom to top, the integrated cooking equipment 100 includes an inner pot 124, an upper mounting plate 121, an electrical component mounting space 123, a top plate 122, a middle partition layer 130, and a cooktop assembly 110.

[0058] Combination Figures 2 to 4 The first cooling fan 140 has a primary air inlet 141 and a primary air outlet 142. The primary air inlet 141 is connected to the electrical component mounting space 123, and the primary air outlet 142 is connected to the intermediate partition 130. When the first cooling fan 140 is running, hot air in the electrical component mounting space 123 enters the first cooling fan 140 through the primary air inlet 141 and is sent into the intermediate partition 130 through the primary air outlet 142.

[0059] like Figure 3 As shown, the second cooling fan 150 has a partition air inlet 151, a cooktop air inlet 152, and a converging air outlet 153. The second cooling fan 150 is a bidirectional suction fan. The second cooling fan 150 has a partition air inlet 151 and a cooktop air inlet 152 that are independent of each other or at least partially separated. The partition air inlet 151 and the cooktop air inlet 152 can be located on different sides of the second cooling fan 150, or they can correspond to different air intake areas or different air intake channels of the second cooling fan 150. The partition air inlet 151 is connected to the middle partition 130, the cooktop air inlet 152 is connected to the internal space 111 of the cooktop, and the converging air outlet 153 is connected to the exhaust port 112. When the second cooling fan 150 is running, the partition air inlet 151 draws in some hot air from the middle partition 130, and the stove air inlet 152 draws in hot air from the stove's internal space 111. The two streams of hot air converge at the second cooling fan 150 and then flow through the converging air outlet 153 to the exhaust outlet 112.

[0060] The second cooling fan 150 can simultaneously or sequentially draw in hot air from the intermediate partition 130 and the internal space 111 of the cooktop, and discharge the two streams of hot air through the converging air outlet 153. Through the above-mentioned bidirectional air intake structure, the second cooling fan 150 can not only exhaust heat from the internal space 111 of the cooktop, but also relay the hot air sent into the intermediate partition 130 by the first cooling fan 140, thereby connecting the electrical component installation space 123, the intermediate partition 130 and the exhaust port 112 of the cooktop assembly 110 in series to form a continuous heat exhaust path.

[0061] In typical integrated cooking appliances, a partition area is usually formed between the cooktop and the cooking components below. This partition area can be used to create a thermal isolation space, structural clearance space, or installation space between the two cooking modules, so as to reduce the impact of the heat generated by the cooking components below on the cooktop, and to provide space for the arrangement of the cooktop chassis, pipes, wiring harnesses, exhaust structure, or heat dissipation structure.

[0062] In this application, the space between the top plate 122 and the cooktop assembly 110 is formed as an intermediate spacer layer 130. The intermediate spacer layer 130 can not only serve as a thermal insulation space or structural arrangement space between the cooktop assembly 110 and the lower cooking assembly 120, but also as an airflow transition space between the first cooling fan 140 and the second cooling fan 150.

[0063] Specifically, the first cooling fan 140 can send hot air from the electrical component mounting space 123 into the intermediate partition 130, and the second cooling fan 150 can draw the hot air from the intermediate partition 130 through the partition air inlet 151 and guide the hot air to the exhaust port 112 for discharge. Thus, the intermediate partition 130 can connect the electrical component mounting space 123 above the lower cooking assembly 120 to the exhaust path of the cooktop assembly 110, reducing the retention of hot air in the electrical component mounting space 123.

[0064] In one embodiment, at least one electrical component, including a power board, a water pump, and a solenoid valve, is installed within the electrical component installation space 123. Since the electrical component installation space 123 is located between the inner tank 124 and the cooktop assembly 110, the heat generated by both the inner tank 124 and the cooktop assembly 110 can cause the temperature within the electrical component installation space 123 to rise. A first cooling fan 140 draws hot air from the electrical component installation space 123 through a primary air inlet 141 and sends the hot air into the intermediate partition 130 through a primary air outlet 142, thereby reducing the ambient temperature around the electrical components such as the power board, water pump, and solenoid valve.

[0065] In one embodiment, at least one of the following components is provided in the internal space 111 of the stove: an operation control panel 113, a valve body, and an igniter. The stove air inlet 152 of the second cooling fan 150 is connected to the internal space 111 of the stove, so that the second cooling fan 150 can draw in hot air around the operation control panel 113, valve body, igniter, and other components, and guide the hot air to the exhaust port 112 through the confluence air outlet 153, thereby reducing the temperature rise of the electrical or functional components in the internal space 111 of the stove.

[0066] The electrical component mounting space 123 between the upper mounting plate 121 and the top plate 122 can be connected to the intermediate partition 130 through the first cooling fan 140. The intermediate partition 130 between the top plate 122 and the cooktop assembly 110 can be connected to the exhaust port 112 of the cooktop assembly 110 through the second cooling fan 150. The first cooling fan 140 sends hot air from the electrical component mounting space 123 into the intermediate partition 130. The second cooling fan 150 then draws hot air from the intermediate partition 130 through the partition air inlet 151 and simultaneously draws hot air from the cooktop internal space 111 through the cooktop air inlet 152. The hot air from the electrical component mounting space 123 and the cooktop internal space 111 converges at the second cooling fan 150 and is then discharged through the exhaust port 112. Therefore, the middle partition 130 can be used as an airflow transition space between the upper and lower modules, allowing the hot air above the lower cooking component 120 to be connected to the exhaust path of the cooktop component 110, reducing the retention of hot air in the electrical component installation space 123. The first cooling fan 140 and the second cooling fan 150 form a two-stage relay heat dissipation structure, which is conducive to the unified discharge of hot air in the electrical component installation space 123 and the hot air in the cooktop internal space 111 to the integrated cooking equipment 100.

[0067] Hot air within the electrical component installation space 123 can be sent into the intermediate partition 130 by the first cooling fan 140, and further drawn out by the second cooling fan 150 before being discharged through the exhaust port 112 of the cooktop assembly 110. In other words, the electrical component installation space 123 does not require a separate external exhaust port; instead, it can be exhausted using the existing exhaust paths of the intermediate partition 130, the second cooling fan 150, and the cooktop assembly 110. This reduces the increased structural complexity caused by separately setting up an exhaust outlet, independent air duct, or additional fan for the electrical component installation space 123, reduces the degree of repetitive air duct arrangement, minimizes the occupation of the limited internal installation space of the entire unit, and helps maintain the simplicity of the integrated cooking equipment 100's appearance.

[0068] In one embodiment, the first cooling fan 140 and the second cooling fan 150 can be activated when the lower cooking assembly 120 performs at least one of the cooking functions of steaming, baking, and microwave heating, or when the cooktop assembly 110 performs a cooktop cooking function. The first cooling fan 140 and the second cooling fan 150 can be activated synchronously to form a continuous heat dissipation path from the electrical component mounting space 123 to the intermediate partition 130 and then to the exhaust port 112.

[0069] In another embodiment, the first cooling fan 140 and the second cooling fan 150 can also be activated separately according to the temperature of the electrical component installation space 123, the internal space 111 of the stove, or the inner liner 124. For example, when the temperature inside the electrical component installation space 123 is high, the first cooling fan 140 is activated to send the hot air in that space into the intermediate partition 130, and the second cooling fan 150 is activated to continue to draw in and discharge the hot air in the intermediate partition 130; when the temperature inside the internal space 111 of the stove is high, the second cooling fan 150 can draw in and discharge the hot air inside the internal space 111 of the stove through the stove air inlet 152.

[0070] like Figure 3 As shown, in one embodiment, the top plate 122 is provided with a ventilation opening 1221 corresponding to the first cooling fan 140. The ventilation opening 1221 connects the electrical component mounting space 123 and the intermediate partition 130. The ventilation opening 1221 allows airflow to connect the upper and lower sides of the top plate 122, facilitating the first cooling fan 140 to send hot air into the intermediate partition 130.

[0071] In this embodiment, the ventilation opening 1221 is an array of circular holes, but this is not a limitation. In other embodiments, the ventilation opening 1221 can be a circular hole, a square hole, a long hole, or an irregularly shaped hole that matches the air outlet profile of the first cooling fan 140.

[0072] like Figure 2 and Figure 3 As shown, in one embodiment, the first cooling fan 140 is located within the electrical component mounting space 123, and the ventilation opening 1221 is aligned with and connected to the primary air outlet 142. The primary air outlet 142 is positioned facing the ventilation opening 1221, and the first cooling fan 140 is installed on the lower side of the top plate 122 or at least partially penetrates the top plate 122. Therefore, the air outlet path of the first cooling fan 140 is shorter, allowing hot air to enter the intermediate partition layer 130 more directly.

[0073] like Figure 3 As shown, in one embodiment, the top plate 122 is provided with a boss 1222, which is located around the ventilation opening 1221 and protrudes towards the intermediate spacer layer 130. Figure 3As shown, in this embodiment, the boss 1222 is provided around the ventilation opening 1221. In other embodiments, the boss 1222 may also be provided on a portion of the periphery of the ventilation opening 1221.

[0074] The boss 1222 raises the structural height around the ventilation opening 1221. When there is a small amount of liquid between the cooktop assembly 110 and the top plate 122, the boss 1222 reduces the risk of liquid entering the electrical component mounting space 123 through the ventilation opening 1221, thereby reducing the impact of liquid on electrical components such as the power board, water pump, and solenoid valve within the electrical component mounting space 123. In addition, the boss 1222 can also serve as a mounting positioning structure or reinforcement structure for the first cooling fan 140 to improve the installation stability of the first cooling fan 140 at the top plate 122.

[0075] like Figure 2 , Figure 3 and Figure 6 As shown, in one embodiment, the cooktop assembly 110 has an exhaust box 114, and a heat dissipation duct 115 is constructed within the cooktop assembly 110. The heat dissipation duct 115 can be formed by a duct housing in the cooktop assembly 110, a structure below the panel 113, or other air guiding structures. The heat dissipation duct 115 is disposed between the confluence air outlet 153 and the exhaust box 114, and the confluence air outlet 153, the heat dissipation duct 115, the exhaust box 114, and the exhaust port 112 are sequentially connected. Hot air discharged from the confluence air outlet 153 enters the heat dissipation duct 115, is guided by the heat dissipation duct 115 to the exhaust box 114, and is discharged through the exhaust port 112.

[0076] like Figure 2 , Figure 3 and Figure 6 As shown, in one embodiment, the height of the heat dissipation duct 115 gradually decreases and its width gradually increases from one end near the second heat dissipation fan 150 to the other end near the exhaust box 114. The heat dissipation duct 115 forms a flattened flow guide structure with gradually decreasing height and gradually increasing width along the airflow direction. This allows the heat dissipation duct 115 to be arranged within the limited height space of the cooktop assembly 110, reducing the space occupied by the heat dissipation duct 115 in the vertical installation direction of the cooktop assembly 110. Simultaneously, the gradually increasing width compensates for the change in flow area caused by the decrease in height, ensuring a relatively stable flow cross-section as the airflow moves from the second heat dissipation fan 150 to the exhaust box 114. This reduces sudden changes in local wind resistance, lowers airflow noise and flow loss, and facilitates the connection between the heat dissipation duct 115 and the exhaust box 114.

[0077] like Figure 6As shown, in one embodiment, the top of the exhaust box 114 is open and connected to the exhaust port 112. The exhaust box 114 has a heat dissipation air inlet 1141, which is located on the side wall of the exhaust box 114. The heat dissipation air duct 115 is connected to the heat dissipation air inlet 1141, so that the heat dissipation airflow enters the exhaust box 114 from the side and then flows to the exhaust port 112 from the top opening.

[0078] like Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the heat dissipation air inlet 1141 is located at the top side of the exhaust box 114, allowing the heat dissipation airflow to enter the exhaust box 114 from the top side and then flow to the exhaust port 112 from the top opening. The heat dissipation air duct 115 is folded upward at one end near the exhaust box 114, allowing the heat dissipation air duct 115 to enter the exhaust box 114 from the top side. The heat dissipation air duct 115 can extend in a low-height space and turn upward to the exhaust box 114 near the exhaust box 114, which is beneficial for adapting to the compact arrangement space within the cooktop assembly 110.

[0079] like Figure 1 and Figure 2 As shown, in one embodiment, the lower cooking assembly 120 further includes an inner liner 124 located below the upper mounting plate 121. The inner liner 124 can be used to form a steaming, baking, or microwave cooking space. The inner liner 124 is connected to an inner liner exhaust pipe 125, which communicates with an exhaust box 114. Hot exhaust gas or steam generated inside the inner liner 124 enters the inner liner exhaust pipe 125 and then enters the exhaust box 114.

[0080] like Figure 1 and Figure 2 As shown, in one embodiment, the exhaust box 114 has an inner liner air inlet 1142, which is located at the bottom of the exhaust box 114. The inner liner exhaust pipe 125 connects to the inner liner air inlet 1142. Since the inner liner 124 is located below the upper mounting plate 121, when the inner liner exhaust pipe 125 is connected to the exhaust box 114 from below, it can communicate with the inner liner air inlet 1142 located at the bottom of the exhaust box 114. Therefore, the exhaust box 114 can simultaneously receive the cooling airflow from the cooling air inlet 1141 and the exhaust from the inner liner 124 via the inner liner air inlet 1142.

[0081] The exhaust box 114 is used to collect the cooling airflow and the exhaust from the inner liner 124. The cooling airflow discharged from the second cooling fan 150 enters the exhaust box 114 through the cooling duct 115 and the cooling air inlet 1141; the hot exhaust gas or steam generated inside the inner liner 124 enters the exhaust box 114 through the inner liner exhaust pipe 125 and the inner liner air inlet 1142. The cooling airflow and the exhaust from the inner liner 124 enter the exhaust box 114 from the top and bottom sides, respectively, and are discharged to the outside through the exhaust port 112 at the top of the exhaust box 114. Thus, the exhaust box 114 can simultaneously perform the function of merging the cooling airflow and the exhaust from the inner liner 124, which helps to reduce the number of exhaust structures and improve the compactness of the overall internal layout.

[0082] like Figure 4 As shown, in one embodiment, the integrated cooking device 100 further includes a heat dissipation assembly 160, which can be used to provide auxiliary heat dissipation for microwave-related components, power boards, or other electrical components. The heat dissipation assembly 160 includes a first fan 161, a first air duct 162, a second fan 163, and a second air duct 164, which are respectively connected to the upper mounting plate 121. The first air duct 162 is connected to the air outlet of the first fan 161 and to the air inlet of the second fan 163, and the second air duct 164 is connected to the air outlet of the second fan 163.

[0083] The airflow output from the first fan 161 flows through the first air duct 162 to the second fan 163, which then sends the airflow into the second air duct 164 to form an auxiliary heat dissipation flow path. The first fan 161, the first air duct 162, the second fan 163, and the second air duct 164 can form a continuous heat dissipation airflow path. The second fan 163 can further draw in or accelerate the airflow sent out by the first fan 161, improving the gas flow capacity within the heat dissipation component 160, thereby enhancing the heat dissipation effect on the relevant components within the electrical component mounting space 123.

[0084] like Figure 4 As shown, in one embodiment, the first cooling fan 140 is located between the first air duct 162 and the second air duct 164, and is located at one end where the air outlet of the second air duct 164 is located. The primary air inlet 141 is connected to the space outside the first air duct 162 and the second air duct 164.

[0085] The first cooling fan 140 can be arranged in the relatively empty area between the first air duct 162 and the second air duct 164, and can draw hot air from the area outside the first air duct 162 and the second air duct 164 to supplement the heat dissipation capacity of the area that the heat dissipation component 160 cannot cover.

[0086] like Figure 4As shown, in one embodiment, the first air duct 162 includes an upstream air duct section 1621 and a downstream air duct section 1622 connected in sequence. The upstream air duct section 1621 is connected to the air outlet of the first fan 161 and is located above the upper mounting plate 121. The downstream air duct section 1622 is connected to the air inlet of the second fan 163 and is located below the upper mounting plate 121. The portion of the heat dissipation assembly 160 except for the downstream air duct section 1622 is located above the upper mounting plate 121.

[0087] The upstream air duct section 1621 and the downstream air duct section 1622 are adapted to the component layout on the upper and lower sides of the upper mounting plate 121, respectively, so that the first air duct 162 can guide air across layers. The main body of the heat dissipation assembly 160 is located above the upper mounting plate 121, which facilitates coordination with the component arrangement in the electrical component mounting space 123.

[0088] In some embodiments, the integrated cooking device 100 further includes a diverter 1623 disposed between the upstream air duct section 1621 and the downstream air duct section 1622, for diverting at least a portion of the airflow within the upstream air duct section 1621 to the downstream air duct section 1622, allowing the airflow to smoothly flow from the upstream air duct section 1621 into the downstream air duct section 1622. This reduces flow loss at the transition point between the upstream and downstream air duct sections 1621 and 1622, improving the continuity and stability of airflow within the first air duct 162. In this embodiment, the first air duct 162 is generally bent, for example, L-shaped, to guide airflow between the upper and lower sides of the upper mounting plate 121.

[0089] In this embodiment, a stove lamp assembly is installed in the downstream air duct section 1622. The stove lamp assembly typically needs to be positioned close to the inner liner 124 to provide illumination to the cooking cavity 1241. A magnetron and a frequency converter are installed in the upstream air duct section 1621. Therefore, by arranging the upstream air duct section 1621 above the upper mounting plate 121 and the downstream air duct section 1622 below the upper mounting plate 121, the first air duct 162 can pass through the areas where the magnetron, frequency converter, and stove lamp assembly are located, respectively. This satisfies the actual installation position requirements of each component while continuously dissipating heat from heat-generating components at different locations.

[0090] The upstream air duct section 1621 of the first air duct 162 is located above the upper mounting plate 121, and the downstream air duct section 1622 is located below the upper mounting plate 121, which allows for the use of the space on both sides of the upper mounting plate 121 to arrange airflow. At the same time, the portion of the heat dissipation assembly 160, except for the downstream air duct section 1622, is located above the upper mounting plate 121, which helps to reduce the space occupied by the heat dissipation assembly 160 on the cooking components and improves the compactness of the overall internal structure.

[0091] like Figure 4As shown, the upper mounting plate 121 is also provided with a circulating air vent 1211, which extends through the upper mounting plate 121 along its height and connects to the downstream air duct section 1622. The air inlet of the second fan 163 is correspondingly or connected to the circulating air vent 1211, allowing the airflow in the downstream air duct section 1622 to flow through the circulating air vent 1211 to the air inlet of the second fan 163. This enables airflow connection between the downstream air duct section 1622 and the second fan 163, allowing the airflow in the first air duct 162 to be further drawn in by the second fan 163 after passing through the downstream air duct section 1622, thereby improving the airflow continuity between the first air duct 162 and the second air duct 164.

[0092] like Figure 5 As shown, in one embodiment, the heat dissipation assembly 160 includes an air guide structure 165, which can be a bracket, an air duct plate, or an air guide shroud. The air guide structure 165 helps to define a second air duct 164, defining multiple air guide layers. In one embodiment, the multiple air guide layers are sequentially distributed along the height direction of the second air duct 164, so that the airflow in the second air duct 164 can be distributed to different levels in the height direction, thereby forming corresponding airflow paths according to the arrangement positions of different heat-generating components in the height direction, reducing the problem of airflow concentrating in a single height area and causing insufficient heat dissipation in other areas.

[0093] The air guide structure 165 is provided with a lateral air outlet 1651 communicating with at least a portion of the air guide layer. The lateral air outlet 1651 is oriented toward the electrical component mounting space 123 located between the first air duct 162 and the second air duct 164. The lateral air outlet 1651 draws airflow from at least a portion of the air guide layer laterally, allowing the airflow to blow toward the electrical component mounting space 123 between the first air duct 162 and the second air duct 164, thereby providing directional heat dissipation for the electrical control components in this area and improving the utilization efficiency of the heat dissipation airflow.

[0094] It is understandable that the side air outlet 1651 can be a long strip, a round hole, a grille, or multiple air outlets spaced apart, and its opening direction can be adjusted according to the position of the electronic control component to be cooled.

[0095] like Figure 5As shown, in one embodiment, the air guiding structure 165 includes a support plate 1653, which defines a second air duct 164 and divides the second air duct 164 into a first air guiding layer 1641 located above the support plate 1653 and a lower air guiding space located below the support plate 1653. The air guiding structure 165 also includes a first guide plate 1652, which is disposed at the bottom of the lower air guiding space and extends toward the support plate 1653. The portion of the lower air guiding space located between the top of the first guide plate 1652 and the support plate 1653 forms the second air guiding layer 1642, and the portion located below the top of the first guide plate 1652 forms the third air guiding layer 1643.

[0096] The support plate 1653 can divide the second air duct 164 into a first air guide layer 1641 and a lower air guide space. The first guide plate 1652 can further divide the lower air guide space into a second air guide layer 1642 and a third air guide layer 1643, thereby realizing multi-layer partitioned air guidance of the second air duct 164, so that components at different heights or positions can obtain corresponding heat dissipation airflow.

[0097] like Figure 5 As shown, in one embodiment, the lateral air outlet 1651 is located upstream of the first guide plate 1652 and communicates with the third air guide layer 1643. The first guide plate 1652 is located on the airflow path within the third air guide layer 1643 and blocks at least a portion of the flow section of the third air guide layer 1643 to guide the gas in the third air guide layer 1643 to flow out from the lateral air outlet 1651 and blow it toward the area that needs heat dissipation, thereby improving the lateral directional air outlet effect and reducing the heat dissipation waste caused by the direct flow of air in the third air guide layer 1643.

[0098] like Figure 7 As shown, in this embodiment, the first guide plate 1652 can block the entire flow section of the third air guide layer 1643. Therefore, when the airflow in the third air guide layer 1643 reaches the first guide plate 1652, it cannot continue flowing downstream in its original direction. Instead, it flows out from the side air outlet 1651 under the blocking and guiding effect of the first guide plate 1652, thereby improving the airflow volume and directional airflow effect of the side air outlet 1651.

[0099] In one embodiment, the integrated cooking appliance 100 has a first heat dissipation branch and a second heat dissipation branch. The first heat dissipation branch is used to exhaust hot air from the electrical component installation space 123, and includes, in sequence: the electrical component installation space 123, a primary air inlet 141, a first cooling fan 140, a primary air outlet 142, a middle partition 130, a partition air inlet 151, a second cooling fan 150, a converging air outlet 153, a cooling duct 115, an exhaust box 114, and an exhaust port 112. The second heat dissipation branch is used to exhaust hot air from the cooktop interior space 111, and includes, in sequence: the cooktop interior space 111, the cooktop air inlet 152, the second cooling fan 150, the converging air outlet 153, the cooling duct 115, the exhaust box 114, and the exhaust port 112.

[0100] The first and second heat dissipation branches converge at the second cooling fan 150 and share the downstream cooling duct 115, exhaust box 114, and exhaust port 112. Thus, the electrical component installation space 123 and the cooktop interior space 111 can share at least a portion of the heat dissipation path, eliminating the need for separate external exhaust channels for each space. This reduces the number of fans, decreases the degree of duct repetition, and improves the compactness of the integrated cooking equipment 100's internal structure.

[0101] The integrated cooking equipment 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the first cooling fan 140, the second cooling fan 150, and / or the heat dissipation component 160 to perform corresponding operations, thereby realizing intelligent control of the integrated cooking equipment 100 and improving the user experience.

[0102] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
