Technical Field

[0001] This application relates to the field of smart home appliances, and in particular to a dual-air duct fan control method for a smart steam oven, and a smart steam oven. Background Technology

[0002] With the improvement of people's living standards and the promotion and popularization of technologies such as the Internet, big data, artificial intelligence, and voice interaction, more and more traditional lifestyles are gradually changing, and the use of cooking equipment is gradually moving towards intelligence. While bringing more convenience to users, the functions of various cooking equipment are also becoming more diversified. As a cooking equipment that integrates multiple functions such as steaming, baking, and fermentation, the level of intelligence of the fermentation function of the steam oven directly affects the success rate of making pasta dishes.

[0003] Traditional steam oven air duct assemblies typically feature a single air duct. These assemblies usually consist of an upper mounting plate, an air duct, and a centrifugal fan, primarily used for exhausting steam from inside the cavity. Traditional single-duct systems only dissipate heat from the cavity itself, not from the door. Summary of the Invention

[0004] Therefore, it is necessary to provide a dual-air duct fan control method for intelligent steam ovens and an intelligent steam oven to address the above-mentioned technical problems.

[0005] In a first aspect, embodiments of this application provide a dual-airflow fan control method for an intelligent steam oven. The intelligent steam oven includes a cavity, a door, and a heat dissipation structure. The heat dissipation structure includes a first fan and a first airflow duct connected to the first fan, a second fan and a second airflow duct connected to the second fan; the first airflow duct is connected to the cavity; when the door is closed, the heat dissipation channel of the door is connected to the second airflow duct; the method includes: Obtain the cooking mode of the intelligent steam oven; According to the cooking mode, the first fan is controlled to operate to dissipate heat from the cavity through the first air duct, and the second fan is controlled to operate to dissipate heat from the door through the second air duct.

[0006] This configuration allows for differentiated and coordinated heat dissipation between the cavity and the door by controlling the two fans to work independently according to the cooking mode. It balances the heat and steam exhaust needs of the cavity with the temperature rise control of the door, effectively improving the overall heat dissipation efficiency and safety performance.

[0007] In some embodiments, when the cooking mode of the smart steam oven is steam mode, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, includes: The first fan is controlled to operate, and after the cooking time of the steaming mode reaches the first preset time, the second fan is controlled to operate for the second preset time.

[0008] With this setup, after the first preset steaming time, the door temperature will gradually rise. At this point, the second fan will be activated to dissipate heat from the door through the second air duct.

[0009] In some embodiments, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, further includes: When cooking is finished, the second fan is stopped, and the first fan is kept running until the first termination condition is met.

[0010] With this setup, the second fan is turned off when cooking ends, while the first fan continues to run until the first end condition is met. The first fan continuously discharges residual steam and heat from the cavity to ensure heat dissipation safety.

[0011] In some embodiments, the first termination condition includes: The first fan operates for a third preset duration or the temperature in the cavity is lower than the first preset temperature.

[0012] This configuration employs a shutdown logic that determines whether the machine will run for a certain period of time or the cavity temperature will fall below the first preset temperature. This ensures that residual steam and heat in the cavity are fully discharged, guaranteeing heat dissipation safety, while also preventing the fan from running ineffectively and continuously, thus balancing heat dissipation reliability and operational efficiency.

[0013] In some embodiments, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, further includes: During the cooking process, determine whether the door is open; When the door is opened, the second fan is controlled to stop working, and the first fan is controlled to work until the first termination condition is met.

[0014] With this setup, the second fan is immediately shut off when the door is open during cooking to prevent hot steam and fumes from entering and contaminating the door's heat dissipation duct. At the same time, the first fan continues to run until the first termination condition is met to exhaust residual steam and heat from the cavity, effectively balancing the reliability of the duct operation with the overall heat dissipation safety of the machine.

[0015] In some embodiments, when the cooking mode of the smart steam oven is the baking mode, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, includes: Control the first fan and the second fan to work simultaneously.

[0016] With this setup, the two fans operate synchronously in baking mode, and the cavity, upper components, and door are cooled by forced convection through independent air ducts. This can quickly remove residual heat from the cavity, reduce the surface temperature of the door, and ensure both the reliability of electrical components and the safety of the door against burns, effectively improving the overall heat dissipation efficiency.

[0017] In some embodiments, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, further includes: When cooking is finished, the second fan is stopped, and the first fan is kept running until the second termination condition is met.

[0018] With this setup, the second fan is turned off when cooking ends, while the first fan continues to run until the second end condition is met. The first fan continuously discharges residual steam and heat from the cavity to ensure heat dissipation safety.

[0019] In some embodiments, the second termination condition includes: The first fan operates for a fourth preset duration or the temperature in the cavity is lower than the second preset temperature.

[0020] This configuration employs a shutdown logic that determines whether the machine will run for a specified period or the cavity temperature will fall below the second preset temperature. This ensures that residual steam and heat in the cavity are fully discharged, guaranteeing heat dissipation safety, while also preventing the fan from running ineffectively and continuously, thus balancing heat dissipation reliability and operational efficiency.

[0021] In some embodiments, controlling the first fan to operate according to the cooking mode to dissipate heat from the cavity through the first air duct, and controlling the second fan to operate to dissipate heat from the door through the second air duct, further includes: During the cooking process, determine whether the door is open; When the door is opened, the second fan is controlled to stop working, and the first fan is controlled to work until the second termination condition is met.

[0022] With this setup, the second fan is immediately shut off when the door is open during cooking to prevent hot steam and fumes from entering and contaminating the door's heat dissipation duct. At the same time, the first fan continues to run until the second termination condition is met to exhaust residual steam and heat from the cavity, effectively balancing the reliability of the duct operation with the overall heat dissipation safety of the machine.

[0023] Secondly, embodiments of this application provide an intelligent steam oven, including a cavity, a door, a heat dissipation structure, and a controller. The heat dissipation structure includes a first fan and a first air duct connected to the first fan, a second fan and a second air duct connected to the second fan; the first air duct is connected to the cavity; when the door is in a closed state, the heat dissipation channel of the door is connected to the second air duct, and the controller is used to execute the steps of the method described in the first aspect.

[0024] This configuration allows for differentiated and coordinated heat dissipation between the cavity and the door by controlling the two fans to work independently according to the cooking mode. It balances the heat and steam exhaust needs of the cavity with the temperature rise control of the door, effectively improving the overall heat dissipation efficiency and safety performance.

[0030] Combination Figures 1 to 3 As shown, the intelligent steam oven includes a cavity 2, a door 1, a heat dissipation structure, and a controller (not shown in the figure). The heat dissipation structure includes a first fan 80 and a first air duct 70 connected to the first fan 80, a second fan 60 and a second air duct 50 connected to the second fan 60; the first air duct 70 is connected to the cavity 2; when the door 1 is in the closed state, the heat dissipation channel of the door 1 is connected to the second air duct 50.

[0031] The heat dissipation structure includes an upper mounting plate 10, a lower air guide plate 20, and an upper air guide plate 40. The upper mounting plate 10 is a thin plate structure, fixed to the top of the cavity 2, serving as the mounting base for each air duct wall panel. The lower air guide plate 20 is located below the upper mounting plate 10, and can be fixedly connected to the lower wall of the upper mounting plate 10 using bolts or other connecting parts. The lower air guide plate 20 and the lower wall of the upper mounting plate 10 enclose an air inlet channel 30. The air inlet channel 30 has air intakes facing the door 1, and the air intakes are spaced apart along the length of the lower air guide plate 20 to cover the lateral heat dissipation area of ​​the door 1.

[0032] The upper air guide plate 40 and the upper wall of the upper mounting plate 10 form a first air duct 70. The first fan 80 is mounted on the upper mounting plate 10 and communicates with the first air duct 70. The first air duct 70 has a second air outlet 71, which is opened side by side with the first air outlet 51 along the width direction of the upper mounting plate 10.

[0033] An upper air guide plate 40 is positioned above the upper mounting plate 10, forming a second air duct 50 with the upper wall of the upper mounting plate 10. The second air duct 50 is independent of the first air duct 70 and there is no airflow connection between them. The second air duct 50 has a first exhaust port 51 that connects to the outside. A second fan 60 is mounted on the upper mounting plate 10, and the air inlet channel 30 is connected to the second air duct 50 via the second fan 60. Driven by the second fan 60, air flows from the air inlet of the door 1 through the air intake into the air inlet channel 30, flows along the air inlet channel 30, passes through the second fan 60, enters the second air duct 50, and is finally discharged to the outside through the first exhaust port 51, forming a complete heat dissipation air duct circulation from the bottom of the door to the door body, then to the lower air guide plate 20, the second fan 60, the upper air guide plate 40, and the outside.

[0034] In this application, when the second fan 60 is running, a negative pressure is formed in the air inlet channel 30. The hot air inside the door 1 flows through the door heat dissipation channel to its air outlet under the action of pressure difference, and is then sucked into the air inlet on the lower air guide plate 20 and enters the air inlet channel 30. The hot air flows along the air inlet channel 30, is pressurized by the second fan 60 and pushed into the second air duct 50, and is finally discharged to the outside of the equipment from the first exhaust port 51. Through this active heat dissipation method, the temperature rise of the door 1 and the handle is effectively reduced.

[0035] In this embodiment, by setting a partition inside the upper air guide plate 40, the space enclosed by the upper air guide plate 40 and the upper wall of the upper mounting plate 10 is divided into two independent air ducts, and an independent fan is configured for each of the two air ducts.

[0036] The first air duct 70, driven by the first fan 80, is used to exhaust steam in the cavity 2 and heat dissipation air from the components above the upper mounting plate 10. The second air duct 50, driven by the second fan 60, is specifically used to exhaust heat dissipation air from the door collected through the air inlet duct 30. Since the two air ducts are independent of each other, the two airflows will not mix or interfere with each other inside the upper air guide plate 40, ensuring their respective exhaust efficiency and heat dissipation performance.

[0037] The heat dissipation structure also includes a water tank 90 disposed above the upper mounting plate 10, and the second exhaust channel 70 is connected to the cavity 2 and used for exhausting steam.

[0038] Based on the above hardware structure, this application provides a dual-air duct fan control method for an intelligent steam oven, which can be executed by a controller. Figure 4 As shown, the method includes the following steps: S402, Obtain the cooking mode of the intelligent steam oven; Smart steam ovens typically include steaming and baking modes.

[0039] S404, according to the cooking mode, control the first fan to work to dissipate heat from the cavity through the first air duct, and control the second fan to work to dissipate heat from the door through the second air duct.

[0040] This configuration allows for differentiated and coordinated heat dissipation between the cavity and the door by controlling the two fans to work independently according to the cooking mode. It balances the heat and steam exhaust needs of the cavity with the temperature rise control of the door, effectively improving the overall heat dissipation efficiency and safety performance.

[0041] In some embodiments, when the cooking mode of the smart steam oven is steam mode, the first fan is controlled to work, and when the cooking time of the steam mode reaches a first preset time, the second fan is controlled to work for a second preset time.

[0042] The first preset duration is, for example, 40 minutes, and the second preset duration is, for example, 10 minutes.

[0043] In the initial stage of steam mode startup, the water inside the cavity rapidly vaporizes upon heating, generating a large amount of high-temperature saturated steam within a short period. This causes a rapid increase in internal pressure, leading to a significant overflow of steam into weakly sealed areas such as door gaps. The area around the door is completely enveloped by a high concentration of hot, humid steam. When the first fan is activated, the first air duct directly connects to the cavity, enabling forced convection to quickly and directionally expel the large amount of steam from the cavity, rapidly reducing the cavity pressure and steam concentration, and significantly minimizing steam overflow from door gaps.

[0044] As the steam mode continues to operate, the high temperature of the cavity will continuously act on the inner side of the door through heat conduction and radiation. Although the door's insulation structure can slow down the temperature rise, heat will continue to accumulate, and the temperature of the door surface (especially the handle area) will gradually rise, eventually exceeding the safe and comfortable temperature for human touch. After the second fan starts, a stable negative pressure is formed in the door's heat dissipation duct, actively drawing in hot air from the door's interlayer. Through forced convection heat exchange, the accumulated heat is quickly removed, precisely controlling the temperature rise of the door and handle, preventing users from being burned by touching them, and at the same time slowing down the high-temperature aging rate of the door's sealing strips and glass components.

[0045] In some embodiments, when the cooking mode of the smart steam oven is steam mode, at the end of cooking, the second fan is controlled to stop working, and the first fan is controlled to work until the first end condition is met.

[0046] When cooking is finished, the second fan is turned off while the first fan continues to run until the first termination condition is met. The first fan continuously discharges residual steam and heat from the cavity to ensure heat dissipation safety.

[0047] The first termination condition includes: the first fan operating for a third preset duration or the temperature in the cavity being lower than the first preset temperature.

[0048] The third preset duration is, for example, 15 minutes. The first preset temperature is, for example, 80℃.

[0049] In this embodiment, a shutdown determination logic is adopted based on the operating time exceeding the target or the cavity temperature falling below the first preset temperature. This ensures that residual steam and heat in the cavity are fully discharged, guaranteeing heat dissipation safety, while also preventing the fan from running ineffectively and continuously, thus balancing heat dissipation reliability and operating efficiency.

[0050] In some embodiments, when the cooking mode of the smart steam oven is steam mode, during the cooking process, it is determined whether the door is open; when the door is open, the second fan is controlled to stop working, and the first fan is controlled to work until the first termination condition is met.

[0051] During the cooking process, the cavity is under high temperature and high humidity positive pressure. Once the door is opened, the cavity is directly connected to the outside environment. The high temperature saturated steam accumulated inside, the hot and humid steam generated during cooking, and the fumes will instantly surge outwards and spread, completely enveloping the area around the door.

[0052] During the cooking process, the opening and closing status of the door is used to determine the operation. When the door is open, the second fan is immediately shut off to prevent hot steam and fumes from entering and contaminating the door's heat dissipation duct. At the same time, the first fan is kept running until the first termination condition is met to exhaust the residual steam and heat from the cavity, effectively balancing the reliability of the duct operation and the overall heat dissipation safety of the machine.

[0053] In some embodiments, when the cooking mode of the smart steam oven is the baking mode, the first fan and the second fan are controlled to work simultaneously.

[0054] In baking mode, the cavity experiences high heat radiation intensity. The door, as the primary heat-insulating surface on the front of the cavity, continuously receives a large amount of radiant heat, resulting in rapid temperature rise and a high final temperature. If the start-up is delayed, like in steam mode, the door temperature will initially rise rapidly, significantly reducing the efficiency of subsequent cooling. Simultaneous operation of dual fans enables forced convection cooling of the door from the initial heating stage, slowing the temperature rise and keeping the door and handle temperatures within a safe range for human touch throughout the heating process, avoiding the risk of burns.

[0055] The upper air guide plate adopts an independent exhaust port design, with the first and second air ducts completely separated and each exhausting its own air. When the second fan and the first fan work simultaneously, the two airflows do not converge or interfere with each other, and there will be no problems of airflow collision or wind pressure cancellation. Both sets of air ducts can maintain the designed air volume, and the heat dissipation efficiency is not affected by parallel operation.

[0056] In the baking mode, the two fans are controlled to run synchronously. Through independent air ducts, the cavity, upper components, and door are subjected to synchronous forced convection heat dissipation. This can quickly remove residual heat from the cavity and reduce the surface temperature of the door, taking into account both the reliability of electrical components and the safety of the door from burns, and effectively improving the overall heat dissipation efficiency.

[0057] In some embodiments, when the cooking mode of the smart steam oven is the baking mode, at the end of cooking, the second fan is controlled to stop working, and the first fan is controlled to work until the second termination condition is met.

[0058] When cooking is finished, the second fan is turned off while the first fan continues to run until the second termination condition is met. The first fan continuously discharges residual steam and heat from the cavity to ensure heat dissipation safety.

[0059] The second termination condition includes: the first fan operating for a fourth preset duration or the temperature in the cavity being lower than the second preset temperature.

[0060] The shutdown logic is based on the operation time of the target or the cavity temperature is lower than the second preset temperature. This ensures that the residual steam and heat in the cavity are fully discharged and the heat dissipation safety is guaranteed. It also avoids the fan running ineffectively and continuously, thus balancing heat dissipation reliability and operating efficiency.

[0061] In some embodiments, when the cooking mode of the smart steam oven is the baking mode, during the cooking process, it is determined whether the door is open; when the door is open, the second fan is controlled to stop working, and the first fan is controlled to work until the second termination condition is met.

[0062] During the cooking process, the opening and closing status of the door is used to determine the operation. When the door is open, the second fan is immediately shut off to prevent hot steam and fumes from entering and contaminating the door's heat dissipation duct. At the same time, the first fan is kept running until the second termination condition is met to exhaust the residual steam and heat from the cavity, effectively balancing the reliability of the duct operation and the overall heat dissipation safety of the machine.

[0063] Figure 5 This is a schematic flowchart illustrating the dual-duct fan control method for an intelligent steam oven in an example embodiment of this application. Figure 5 As shown, the specific steps include: S501, after the control process is started, the system first determines whether the current operating mode of the steam oven is steam mode or baking mode, and enters the corresponding control branch according to the determination result.

[0064] S502, if the system determines that it is in steam mode, the system immediately starts the first fan and discharges steam and residual heat to the inner cavity through the first air duct, while simultaneously dissipating heat from the electrical components in the upper mounting plate area.

[0065] S503, the system records the cooking time of the steaming mode in real time and determines whether the cooking time is greater than or equal to 40 minutes. If the continuous running time of the steaming function is less than 40 minutes, the system maintains the state of only the first fan running and jumps to step S502.

[0066] S504, if the continuous operation time of the steaming function is greater than or equal to 40 minutes, the system starts the second fan, which forces heat dissipation on the door through the second air duct, and controls the second fan to run continuously for 10 minutes.

[0067] S505, After the second fan starts, the system monitors the door control signal in real time to determine whether the door is open. If the door is determined to be open, proceed to step S507.

[0068] S506, if it is determined that the door is not open, the system determines whether the current cooking program has ended. If it is determined that the cooking program has not ended, the system returns to step S505; if it is determined that the cooking program has ended, it jumps to step 507.

[0069] S507 controls the second fan to stop working, the first fan to stop working after running continuously for 15 minutes, or the first fan to continue running until the temperature inside the cavity is below 80℃.

[0070] S508, if the baking mode is determined in step S501, the system simultaneously starts the first fan and the second fan; the first fan performs heat dissipation of the cavity and heat dissipation of the upper electrical components through the first air duct, and the second fan performs forced heat dissipation of the door through the second air duct.

[0071] SS509, During the baking mode operation, the system monitors the door control signal in real time to determine whether the door is open. If the door is determined to be open, proceed to step S511.

[0072] S510, if it is determined that the door is not open, the system determines whether the current cooking program has ended; if the program has not ended, it returns to step S509 to check repeatedly; if the program has ended, it jumps to step S511.

[0073] S511, the first fan stops working after running continuously for 15 minutes, or the first fan continues to run until the temperature inside the cavity is below 80℃.
