[0025] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0026] Example 1 An embodiment of the present invention provides an integrated stove, comprising: at least one cooking unit and a control module; Figure 1The embodiment of the invention shown is a structural schematic diagram of a cooking unit, which includes: a cooking cavity 110, an exhaust duct 120, an exhaust valve mechanism 130 and an exhaust fan module 140; the exhaust duct 120 is connected to the cooking cavity 110; the exhaust valve mechanism 130 is arranged on the exhaust duct 120; the exhaust fan module 140 is arranged in the cooking cavity 110; the exhaust valve mechanism 130 and the exhaust fan module 140 are both communicatively connected to a control module; the exhaust duct 120 is used to form an air flow passage between the cooking cavity 110 and the external space; the exhaust valve mechanism 130 is used to control the opening and closing of the exhaust duct 120; the exhaust fan module 140 is used to discharge the gas in the cooking cavity 110 along the air flow passage; the control module is used to generate a control signal based on a preset cooking recipe and control the exhaust valve mechanism 130 and the exhaust fan module 140 based on the control signal; wherein the cooking recipe includes: at least one cooking stage.

[0027] Specifically, the cooking cavity 110 is the core part of the integrated stove, which is used to accommodate ingredients and carry out the cooking process. It is usually made of high-temperature resistant materials and can withstand long-term use in high-temperature environments. The design of the cooking cavity 110 takes into account thermal efficiency and safety to ensure that the food is evenly heated during the cooking process and does not pose any safety hazards to the user. The exhaust duct 120 is connected to the cooking cavity 110 to form an airflow passage between the cooking cavity 110 and the external space. The exhaust duct 120 is designed to effectively remove the smoke, oil smoke and odor generated during the cooking process, keeping the kitchen environment clean and comfortable. The exhaust duct 120 is usually made of corrosion-resistant materials to ensure its stability and durability for long-term use. The exhaust valve mechanism 130 is arranged on the exhaust duct 120 to control the opening and closing of the exhaust duct 120. The exhaust valve mechanism 130 can adjust the exhaust flow rate as needed to adapt to different cooking needs. For example, when cooking at high temperatures, the exhaust valve mechanism 130 can be opened to increase the exhaust flow rate and quickly remove smoke and odors; while in low-temperature cooking or the heat preservation stage, the exhaust valve mechanism 130 can be closed to reduce energy loss. The design of the exhaust valve mechanism 130 should be flexible and reliable to ensure that the user can conveniently control the exhaust flow rate. The exhaust fan module 140 is arranged in the cooking cavity 110 and is used to discharge the gas in the cooking cavity 110 along the air flow path. The exhaust fan module 140 is usually composed of an efficient motor and a wind wheel, which can generate a strong airflow to quickly remove smoke and odors. The design of the exhaust fan module 140 should take into account noise control and energy efficiency to ensure that it is both quiet and energy-saving during use.

[0028] The exhaust valve mechanism 130 and exhaust fan module 140 are both communicatively connected to a control module. The control module is configured to generate control signals in response to user actions and control the exhaust valve mechanism 130 and exhaust fan module 140 based on these control signals. These actions can include preset recipes, sensor signals, or user actions. Through communication with the control module, the exhaust valve mechanism 130 and exhaust fan module 140 can be adjusted and controlled accordingly based on different user actions, achieving an intelligent cooking process.

[0029] The control module is the brain of the integrated stove, responsible for receiving and processing various operational actions and generating corresponding control signals. The control module may include components such as a microprocessor, memory, and input / output interfaces. The microprocessor is responsible for executing various algorithms and logical operations, while the memory is used to store information such as recipe flows, sensor data, and user settings. The input / output interface is used to exchange data with the exhaust valve mechanism 130, exhaust fan module 140, and other external devices.

[0030] Operational actions are one of the ways users interact with integrated stoves. A preset recipe process refers to pre-set cooking steps and parameters. Users only need to select the corresponding recipe, and the integrated stove will automatically perform the corresponding operation. Different recipes include different cooking processes, and each cooking process includes a different number of cooking stages. For example, a recipe for baking egg tarts usually includes only one cooking stage, which includes multiple steps, such as baking at a lower temperature for a certain period of time, and then baking at a higher temperature for a period of time. A recipe for baking pie includes two cooking stages, and the first and second cooking stages require the user to flip the pie.

[0031] In some preferred embodiments of the present invention, multiple cooking stages of a recipe are defined through user operations, that is, user operations are required between two consecutive cooking stages, and the operations include but are not limited to operations on ingredients and operations on the integrated stove.

[0032] The control module can also generate control signals based on sensor signals and user actions. Sensor signals refer to data collected by various sensors built into the integrated cooker, such as temperature sensors and smoke sensors. This data can be used to monitor environmental changes during the cooking process and make corresponding adjustments as needed. User actions refer to direct operations performed on the integrated cooker through buttons, touch screens, or other means, such as turning the cooker on and off, adjusting the temperature, etc.

[0033] For multi-step recipe control and cooking results, recipes often require control reminders such as flipping. Current machines require users to pause and then open the door to flip the food. This often results in excessive steam or heat blowing in, making the user experience extremely poor.

[0034] Furthermore, in some preferred embodiments of the present invention, the cooking recipe includes: a continuous first cooking stage and a second cooking stage; the control signal includes: an exhaust signal and a continue cooking signal; the control module is also used to control the exhaust valve mechanism 130 to open the exhaust pipe 120 based on the exhaust signal after the first cooking stage, and to turn on the exhaust fan module 140 until the preset exhaust conditions are reached; after the preset exhaust conditions are reached, the integrated stove is controlled to enter the cooking waiting stage; in response to the end waiting signal, the second cooking stage is executed based on the continue cooking signal.

[0035] For details, see Figure 2 The embodiment of the present invention shown is a flow chart of automatic exhaust according to a preset recipe.

[0036] The user starts a multi-stage steaming and baking recipe through the button operation end of the device; after completing the first cooking stage of the recipe, the exhaust valve and exhaust fan are automatically opened to exhaust the hot air or steam outside the cavity; when the exhaust is completed for a period of time (preferably 1-10 minutes), the flip reminder function is immediately responded to, and the user is required to flip the dish over. After this exhaust, the hot air / steam will not hit the user when the user opens the door, making the cooking process safer and improving the user experience; after the user opens the door to flip the dish over, the next recipe function is immediately entered to continue cooking until cooking is completed; if the user has not opened the door to flip the dish over, after waiting for a period of time (preferably 1-3 minutes), the second cooking stage function is immediately entered to continue cooking until cooking is completed; the exhaust process reminder is displayed in the operation display area 150 to remind the user.

[0037] The present invention provides an integrated stove, which includes: at least one cooking unit and a control module; the cooking unit includes: a cooking cavity 110, an exhaust pipe 120, an exhaust valve mechanism 130 and an exhaust fan module 140; the exhaust pipe 120 is connected to the cooking cavity 110; the exhaust valve mechanism 130 is arranged on the exhaust pipe 120; the exhaust fan module 140 is arranged in the cooking cavity 110; the exhaust valve mechanism 130 and the exhaust fan module 140 are both communicatively connected to the control module; the exhaust pipe 120 is used to form an air flow between the cooking cavity 110 and the external space path; the exhaust valve mechanism 130 is used to control the opening and closing of the exhaust pipe 120; the exhaust fan module 140 is used to discharge the gas in the cooking cavity 110 along the airflow path; the control module is used to generate a control signal based on a preset cooking recipe, and control the exhaust valve mechanism 130 and the exhaust fan module 140 based on the control signal; wherein, the cooking recipe includes: at least one cooking stage; through intelligent analysis of the cooking process of the preset recipe, the exhaust is reasonably carried out, the exhaust efficiency is improved, and a more comfortable, healthy and safe cooking environment is provided to the user, thereby improving the user experience.

[0038] Example 2 Based on the above embodiment, during the cooking process, the integrated cooktop can also exhaust cooking cavity 110 based on various sensor signals to ensure a safe and reliable cooking process. In some preferred embodiments of the present invention, the cooking unit further includes a cavity pressure sensor disposed within cooking cavity 110, configured to collect pressure information within cooking cavity 110 and transmit the pressure information to a control module. The control module generates a first control signal based on the pressure information and controls exhaust valve mechanism 130 and exhaust fan module 140 based on the first control signal.

[0039] Specifically, the cavity pressure sensor is arranged inside the cooking cavity 110, and its main function is to monitor and collect the pressure information inside the cooking cavity 110 in real time. During the cooking process, the pressure inside the cavity will change with the change of temperature. For example, when cooking at high temperature, the pressure inside the cavity may increase significantly, which will affect the cooking effect and safety of the food. Therefore, by monitoring the pressure changes in real time, it can be ensured that the cooking process is carried out in the best state. The pressure information collected by the cavity pressure sensor will be sent to the control module in real time. After receiving this information, the control module will analyze and process it according to the preset algorithm to generate a corresponding first control signal. This control signal is the key basis for adjusting the exhaust valve mechanism 130 and the exhaust fan module 140 based on the current pressure conditions.

[0040] When the pressure within the cooking cavity exceeds a set safety threshold, the control module immediately generates a first control signal, instructing the exhaust valve mechanism 130 to open to release excess pressure. Simultaneously, the exhaust fan module 140 increases its speed to accelerate gas exhaust. This prevents safety hazards caused by excessive pressure, such as deformation or explosion of the cooking cavity 110. During normal cooking, if the pressure remains within a moderate range, the control module fine-tunes the opening of the exhaust valve mechanism 130 and the speed of the exhaust fan module 140 based on the pressure information to achieve optimal exhaust efficiency and energy efficiency. This refined control not only improves cooking efficiency but also saves energy. In certain cooking scenarios, such as when maintaining a certain pressure environment to promote the absorption of ingredients or maintain a specific taste, the control module will also appropriately adjust the operating conditions of the exhaust valve mechanism 130 and exhaust fan module 140 based on the pressure information to ensure that the pressure within the cooking cavity does not drop too low.

[0041] To enhance the user experience, integrated stoves can also display current cavity pressure information and control status via a display or mobile app. Users can intuitively understand pressure changes during cooking and manually intervene or adjust as needed. Furthermore, integrated stoves can be equipped with intelligent reminders to promptly alert users to take appropriate measures when pressure abnormalities occur.

[0042] Furthermore, in some preferred embodiments of the present invention, the cooking unit also includes: a cavity temperature sensor; the cavity temperature sensor is arranged inside the cooking cavity 110, and the cavity temperature sensor is used to collect temperature information inside the cooking cavity 110 and send the temperature information to the control module; the control module generates a second control signal based on the temperature information, and controls the exhaust valve mechanism 130 and the exhaust fan module 140 based on the second control signal.

[0043] Specifically, the cavity temperature sensor is arranged inside the cooking cavity 110, and its main function is to collect temperature information inside the cooking cavity 110 in real time. During the cooking process, temperature is a key factor affecting the taste, nutrient retention and safety of food. Therefore, by monitoring temperature changes in real time, it can be ensured that food is cooked at the optimal temperature to avoid overheating or undercooking. The temperature information collected by the cavity temperature sensor will be sent to the control module in real time. After receiving this information, the control module will analyze and process it according to the preset algorithm to generate a corresponding second control signal. This control signal is the key basis for adjusting the exhaust valve mechanism 130 and the exhaust fan module 140 based on the current temperature conditions.

[0044] When the temperature inside the cavity exceeds a set safety threshold, the control module immediately generates a second control signal, instructing the exhaust valve mechanism 130 to open to release excess heat. Simultaneously, the exhaust fan module 140 increases its speed to accelerate the exhaust of hot air. This prevents the risk of food burning or the production of harmful substances due to excessive temperatures. During low-temperature cooking, if the temperature remains within a moderate range, the control module fine-tunes the opening of the exhaust valve mechanism 130 and the speed of the exhaust fan module 140 based on the temperature information to achieve optimal heat retention and energy efficiency. This refined control not only improves cooking efficiency but also saves energy. In certain cooking scenarios, such as those requiring a constant temperature environment to promote even heating of ingredients or maintain a specific texture, the control module will also appropriately adjust the operating conditions of the exhaust valve mechanism 130 and exhaust fan module 140 based on the temperature information to ensure that the temperature inside the cavity does not fluctuate excessively.

[0045] To enhance the user experience, integrated stoves can also display current cavity temperature information and control status via a display or mobile app. Users can intuitively understand temperature fluctuations during cooking and manually intervene or adjust as needed. Furthermore, integrated stoves can be equipped with intelligent reminders to promptly alert users to take appropriate measures when temperature abnormalities occur.

[0046] Furthermore, in some preferred embodiments of the present invention, the cooking unit further includes: a door lock; the door lock is communicatively connected to the control module, and the control module is configured to generate a control signal in response to an operating action and control the door lock based on the control signal.

[0047] Specifically, the door lock's primary function is to control the opening and closing of cooking cavity 110. This design ensures that users cannot open cooking cavity 110 at will during cooking, thereby preventing burns or other safety incidents caused by misoperation. Furthermore, the door lock prevents children or pets from accidentally touching cooking cavity 110, further enhancing safety for home use.

[0048] Furthermore, the introduction of pressure sensors and / or temperature sensors can enable the integrated stove to achieve automatic exhaust during automatic operation, see Figure 3 The figure shows an automatic exhaust flow chart of an integrated stove provided by an embodiment of the present invention.

[0049] The user starts the steaming and baking function through the key operation end of the device; after the function is started, the control system will perform PID temperature control according to the temperature sampling of the temperature sensor to control the cavity temperature to reach a balance; the control system will sample in real time according to the pressure of the cavity sensor; when the cavity temperature reaches the preset temperature threshold (preferably 85℃ for the steaming function and 150℃ for the baking and frying function), the locking function is activated to prevent users from being scalded by steam / hot air when opening the door; the door lock function startup condition can also be assisted by the cavity pressure sensor monitoring. When the cavity pressure value is greater than the preset threshold, it can be used as one of the conditions for starting the door lock function.

[0050] Furthermore, to save costs, only one pressure sensor and one temperature sensor can actually be designed. The pressure value and temperature value can be converted through thermodynamic formulas, and different thresholds can be designed. When one value reaches the threshold, the locking operation is triggered.

[0051] Specifically, in theory, the pressure and temperature of hot air conform to the ideal gas state equation of thermodynamics: P=ρRT; where P is the cavity pressure value, ρ is the hot gas density, R is the gas constant, and T is the cavity temperature value; for example: when the steamer temperature is 103 degrees, the steam pressure is approximately 0.23 MPa (megapascals).

[0052] It should be noted that the temperature and pressure of the steamer are affected by many factors, such as the volume of the steamer, the circulation of steam, the heating method and heating time, etc. Therefore, the specific situation may vary.

[0053] Furthermore, when the pressure value inside the cavity fluctuates greatly, or the pressure value continues to rise and reaches the pressure threshold corresponding to the corresponding cavity temperature, the cavity automatically opens the exhaust valve and exhaust fan to discharge the hot air out of the cavity; during the exhaust process, a reminder is displayed on the operation display to remind the user.

[0054] For details, see Figure 4The embodiment of the present invention provides a schematic diagram of a normal pressure value change. As the working time goes by, the cavity is not completely sealed, and the final cavity pressure P can also reach equilibrium after the temperature is balanced. Figure 5 The schematic diagram of a cavity pressure fluctuation provided by an embodiment of the present invention is shown. After the exhaust function is started, the pressure P in the body fluctuates within a certain range as time goes by, and the exhaust is finally turned off after reaching equilibrium.

[0055] Furthermore, in some preferred embodiments of the present invention, the cooking unit also includes: a gate pressure sensor; the gate pressure sensor is arranged on the door body of the cooking cavity 110, and the gate pressure sensor is used to collect the user's operating actions and send the user's operating actions to the control module; the control module generates a third control signal based on the user's operating actions, and controls the exhaust valve mechanism 130 and the exhaust fan module 140 based on the third control signal.

[0056] Specifically, the gate pressure sensor is used to monitor the knock signal control, mainly for functional exhaust or the user knocks on the door to actively remind the machine to interrupt control; different knocking methods can be designed, for example: double-click for exhaust, triple-knock for pause, etc.

[0057] Furthermore, in some preferred embodiments of the present invention, the control module generates a control signal based on the user's operation action, and controls the door lock based on the control signal.

[0058] For details, see Figure 6 The embodiment of the present invention shown in the figure provides a schematic diagram of door pressure changes. The door pressure P has three peaks, indicating that the user knocks on the door three times in a row. The system can be set to automatically open the door lock after knocking on the door three times.

[0059] Furthermore, the control module can also convert the pressure signal into a voltage digital signal using the following formula: ; in, is a voltage digital signal, is the pressure signal, is the reference voltage of the pressure signal, and n is the number of sampling bits.

[0060] The pressure signal is converted into a digital voltage signal, which the controller then analyzes to determine the user's intent. For example, the controller can analyze parameters such as the frequency and intensity of the tapping to distinguish whether it is a request to open or close the door, or some other type of interaction. Based on the analysis results, the controller generates a corresponding second gate control signal. This signal can be a door opening or closing signal, depending on the specific tapping pattern.

[0061] The door lock can be an automatic door-opening mechanism, and the generated control signal is sent to the automatic door-opening mechanism. Based on the received signal, the automatic door-opening mechanism performs a corresponding action, such as opening or closing the door of the cooking cavity 110. This process is fully automated, providing a safe and efficient way to respond to user operational needs. By allowing users to control the opening and closing of the door with a simple and intuitive tapping action, this approach greatly enhances the user-friendliness and interactivity of the integrated stove.

[0062] Furthermore, the door lock is an automatic door opening mechanism, and the door opening angle can be controlled. During the exhaust process, if the pressure value of the detected cavity drops to a certain reference value (according to actual tests, opening the door does not generate a large amount of steam under this pressure condition), the door can be automatically opened to a certain angle (preferably 10° to prevent the door gap from being too large, which may cause safety accidents due to the user's inattention) to speed up the exhaust efficiency; when the cavity pressure and temperature reach a low temperature and low pressure state, the door will automatically close.

[0063] The door opening speed can be controlled. When exhausting, the door opening speed can be controlled to the maximum speed (Vmax) to ensure exhaust at the maximum speed at a small angle, thereby improving the exhaust efficiency. Normally, the door is opened at a safe speed (Vvalue) to ensure the safety of the door opening at this speed and the life evaluation of the door control.

[0064] See also Figure 7 The embodiment of the present invention provides a schematic diagram of a door pressure digital signal change, where the horizontal axis represents the sampling time t and the vertical axis represents the sampled voltage digital signal V.

[0065] The sampled voltage digital signal V is 0-Vad1, which defaults to the door-open state. In some preferred embodiments of the present invention, the preferred Vad1 parameter is determined according to the hardware sampling parameter.

[0066] The sampled voltage digital signal V is Vad2-Vad4, which is in the door-closed state by default. In some preferred embodiments of the present invention, the parameters of Vad2 and Vad4 are determined according to the hardware sampling parameters.

[0067] In the closed state, the sampled voltage digital signal V is in continuous fluctuation, and condition 1: the fluctuation difference of the sampled voltage digital signal V is greater than △Vad1= Vad5- Vad3. In some preferred embodiments of the present invention, the preferred scheme △Vad1 parameter is determined according to the hardware sampling parameters; condition 2: the number of sampling changes needs to be greater than the number of knocking. In some preferred embodiments of the present invention, the number of knocking is preferably more than 2 times to prevent knocking caused by other external factors; condition 3: the duration of the knocking sampling voltage is △t=t2-t1, △t needs to be greater than the set threshold range. In some preferred embodiments of the present invention, △t>50ms is preferred; that is, the change range of the voltage digital signal for multiple consecutive times is greater than the preset voltage difference, and the duration of each voltage digital signal change exceeding the preset second voltage value exceeds the preset time value, and an open signal is generated.

[0068] By detecting and processing the pressure signal from the user tapping the cooking cavity door 110, the integrated stove's exhaust control system not only improves operational safety and efficiency, but also enhances the user's interactive experience with the appliance. This intelligent and user-friendly design meets the modern family's demand for smart kitchen appliances, making cooking easier and more enjoyable.

[0069] Furthermore, the user starts the integrated stove steam oven through the button operation end of the device; when the user actively needs to open the door in the middle and has not entered the locking function (steam / hot air has not formed high temperature), the user can open the door directly without performing the exhaust function; when the user actively needs to open the door in the middle and has locked the door to complete the function.

[0070] The user can operate the "Exhaust" button to exhaust the air through the operation button part, and the exhaust function will be displayed in the display area. The cavity will automatically open the exhaust valve and exhaust fan to exhaust the hot air outside the cavity; after the exhaust is completed, the user will be reminded to open the door; the user double-clicks the corresponding cavity door, and the control system monitors the pressure change feedback through the pressure sensor, and the cavity will automatically open the exhaust valve and exhaust fan to exhaust the hot air outside the cavity; after the exhaust is completed, the user will be reminded to open the door.

[0071] Furthermore, in some preferred embodiments of the present invention, the integrated stove also includes: an anti-backdraft device; the anti-backdraft device is connected to the exhaust pipe 120, and the anti-backdraft device is used to prevent external gas from flowing back into the cooking cavity 110 through the air flow passage.

[0072] Specifically, the backdraft prevention device is one of the most important safety components in the integrated stove. Its main function is to prevent external air from flowing back into the cooking cavity 110 through the airflow path. This design can effectively prevent external odors, harmful gases or smoke from entering the cooking area, thereby ensuring the health and safety of the user.

[0073] During cooking, if there are any foreign odors (such as garbage or paint) present, the backdraft prevention device prevents these odors from entering the cooking cavity 110 through the airflow path, ensuring the purity and taste of the food. In some cases, harmful gases (such as carbon monoxide and hydrogen sulfide) may be present in the external environment. The backdraft prevention device effectively blocks these gases from entering the cooking area, protecting the health of the user. In emergency situations such as fires, the backdraft prevention device also prevents smoke from spreading through the airflow path into the cooking cavity 110, buying valuable time for rescuers.

[0074] Furthermore, in some preferred embodiments of the present invention, the integrated stove also includes: a fire prevention device; the fire prevention device is connected to the exhaust pipe 120, and the fire prevention device is used to cut off the air flow path.

[0075] Specifically, fire prevention devices are primarily used to cut off airflow to prevent the spread and expansion of fire. This design can quickly cut off the oxygen supply when a fire breaks out, effectively controlling the fire and minimizing losses.

[0076] Fire prevention devices typically utilize sensitive sensors and efficient actuators to rapidly cut off airflow and effectively control the fire within a short period of time. Fire prevention devices are designed with safety and reliability in mind, ensuring they maintain excellent performance and stability over extended periods of use. Their relatively simple structure makes them easy to install and maintain. Users simply need to perform regular inspections and maintenance according to the user manual to ensure proper operation.

[0077] Furthermore, in some preferred embodiments of the present invention, the integrated stove also includes: a gas detection device; the gas detection device is used to collect gas data in the airflow path and send the gas data to the control module; the control module is used to generate a fourth control signal based on the gas data, and control the exhaust valve mechanism 130 and the exhaust fan module 140 based on the fourth control signal; the control module is also used to issue an alarm based on the fourth control signal.

[0078] Specifically, the gas detection device is a key component of the integrated stove, collecting gas data within the gas flow path. It monitors the concentration and composition of the gas in real time and transmits this data to the control module for processing. Based on this data, the control module generates corresponding control signals to control the operating status of the exhaust valve mechanism 130 and exhaust fan module 140, and issues an alarm to alert the user to safety.

[0079] The gas detection device monitors gas data within the airflow path in real time, ensuring users are always informed of gas usage and safety. Control signals generated based on this gas data enable intelligent control of the exhaust valve mechanism 130 and exhaust fan module 140. When the gas concentration is too high, the control module instructs the exhaust valve mechanism 130 to close or reduce its opening to reduce the gas concentration; it also instructs the exhaust fan module 140 to accelerate its operation to expel excess gas. This intelligent control approach not only improves the safety of the integrated stove but also saves energy. When the gas detection device detects an abnormality (such as a gas leak or excessive gas concentration), it immediately issues an alarm to alert the user. This timely warning mechanism effectively prevents accidents and safeguards the personal and property safety of users.

[0080] Furthermore, in some preferred embodiments of the present invention, the integrated stove includes: two cooking units.

[0081] For details, see Figure 8 The schematic diagram of an integrated stove according to an embodiment of the present invention shows two independent cooking chambers 110, each equipped with an independent exhaust system. This design effectively prevents the cross-contamination of fumes and odors between different cooking tasks, improving exhaust efficiency. Each cooking chamber 110 has an independent exhaust port on its back panel, carefully positioned to ensure that fumes and steam are quickly drawn in and discharged.

[0082] An embodiment of the present invention provides an integrated stove, and the combined application of a door lock function and an exhaust function can solve the safety accidents caused by steam / hot air rushing in the user's face during the cooking process or when the door is opened after cooking, thereby improving the user's cooking and usage experience; the automatic exhaust method can improve cooking efficiency, and the design is more intelligent and humane; the manual exhaust method gives users more choices when cooking, and opening the door is safer and smarter.

[0083] Example 3 Based on the above embodiments, an embodiment of the present invention provides an integrated stove control method, including: generating a control signal based on a preset cooking recipe; wherein the cooking recipe includes: at least one cooking stage; and controlling the exhaust valve mechanism 130 and the exhaust fan module 140 based on the control signal.

[0084] Those skilled in the art can clearly understand that, for the convenience and brevity of description, the specific working process of the integrated stove control method described above can refer to the corresponding process in the aforementioned integrated stove embodiment, and will not be repeated here.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
