[0002] As people's consumption level improves, life becomes more intelligent. In particular, in order to simplify the cooking process, more automatic cooking is performed. Modern kitchens are surrounded by intelligent electrical appliances. Since less nutrition is lost during the steaming process and the original taste of the food can be preserved, baked food is also popular among people. Furthermore, under the condition of limited kitchen space, steaming and baking equipment that can both bake and steam can fully meet people's needs for food cooking, and effectively reduce the space occupied by the original separate steamer and oven in the kitchen, which is widely welcomed by consumers.

[0070] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0071] In an exemplary embodiment, the control method of the steaming and baking device provided in the present application can be applied to Figure 1In the application environment shown, the application environment involves a steaming and baking device 102 and a controller 104, and the controller 104 is located outside the steaming and baking device 102. In some embodiments, the steaming and baking device 102 may further include the controller 104. The steaming and baking device 102 may communicate with the controller 104 via a network or other means. The data storage system may store data that the controller 104 needs to process. The data storage system may be integrated on the controller 104, or may be placed on a cloud or other network server.

[0072] The steaming and baking device 102 at least includes a data acquisition device, and the controller 104 is connected to the data acquisition device. The controller 104 is used to obtain the operating status data of the steaming and baking device 102 collected by the data acquisition device, and implement the door opening protection for the steaming and baking device 102. Specifically, when predicting that the user has opened the door of the steaming and baking device 102, the controller 104 obtains the operating status data of the steaming and baking device 102, performs a safety risk analysis based on the operating status data, and determines whether it is necessary to perform the door opening protection. When it is determined that it is not necessary to perform the door opening protection, the steaming and baking device 102 is controlled to perform the door opening action in response to the door opening operation; when it is determined that the door opening protection needs to be performed, the steaming and baking device 102 is controlled to perform the door opening protection action.

[0073] Among them, the steaming and baking device 102 can be various types of household or commercial steaming and baking devices. As long as the steaming and baking device 102 includes a door body that can perform a door opening action, the control method provided in the present application can be applied to realize door opening protection. For example, it can be a desktop steaming oven that can be placed on a countertop, or it can be a built-in steaming oven fixedly installed in a cabinet or other location, or it can be an all-in-one microwave steaming and baking machine. The controller 104 can be an electronic device, such as a control chip, a control circuit board, a terminal or a server. The terminal can be, but is not limited to, various personal computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, etc. The server can be implemented as an independent server or a server cluster composed of multiple servers.

[0074] In an exemplary embodiment, Figure 2 As shown, a control method for a steaming and baking device is provided, and the method is applied to Figure 1 The controller 104 in FIG. 1 is taken as an example to illustrate, and the following steps 202 to 206 are included. Among them:

[0075] Step 202: when it is predicted that the user will open the door of the steaming and baking device, the operating status data of the steaming and baking device is obtained.

[0076] It is understandable that the user may open the door of the steaming and baking device when the cooking process of the steaming and baking device is finished, when the user needs to place or take out food in the cooking cavity of the steaming and baking device, or when the door of the steaming and baking device needs to be opened. Figure 3 As shown, the user can open the door of the steaming and baking device by pulling the door by the handle, so that the door rotates around the box body and the cooking cavity is displayed to the outside through the opening. Of course, the user can also press the door opening button to automatically rotate the door around the box body and display the cooking cavity to the outside through the opening.

[0077] Specifically, the user's door opening operation is predicted, that is, it is identified whether the user has the intention to open the door. The prediction method can be that the steaming and baking device has run to the end node of the cooking process. At this time, the food has been cooked, and the user will definitely open the door of the steaming and baking device to take out the cooked food. The user's door opening operation is predicted, or it can be detected during the cooking process of the steaming and baking device that the user is preparing to open the door due to the need to place or take out the food in the cooking cavity. Among them, the user's behavior of preparing to open the door can be a behavior of approaching the steaming and baking device, a behavior of touching the door, or a behavior of applying pressure to the door.

[0078] Exemplarily, the prediction in step 202 that the user has opened the door of the steaming and baking device includes: receiving user behavior status data fed back by a user behavior monitoring device.

[0079] Among them, based on the different types of user behavior status data, different user behavior monitoring devices can be used to realize data collection. It can be understood that the user behavior monitoring device is intended to predict whether the user has the intention to open the door of the steaming and baking device by sensing the user's position and action in real time. Furthermore, when the user tries to open the door at an inappropriate time, the potential danger caused by the door opening operation can be judged and prevented based on the prediction results.

[0080] In this embodiment, taking the need to detect the user's behavior of approaching the steaming and baking device as an example, the user behavior monitoring device can be a proximity sensor or an infrared sensor and other devices, and the user behavior status data corresponds to the user approaching the device behavior. Figure 3 , a proximity sensor or infrared sensor can be set on the outside of the door or box. Taking the detection of the user's touching the door as an example, the user behavior monitoring device can be a contact sensor or other device, and the user behavior status data is the contact data. Taking the detection of the action of applying pressure to the door as an example, the user behavior monitoring device can be a pressure sensor or other device, and the user behavior status data is the feeling of pressing. Among them, please continue to refer to Figure 3The contact sensor and the pressure sensor can be set at a door handle or a door opening button.

[0081] For example, the controller predicts that the user has opened the door of the steam-bake device, and this can be obtained without the aid of a newly added user behavior monitoring device. Taking the steam-bake device as an example, the controller may receive node information of reaching the end node of the cooking process fed back by an internal timer, or the controller may receive door opening information fed back by an interactive device of the steam-bake device.

[0082] Furthermore, after the steam-bake device starts working, the controller needs to continuously monitor whether the user has opened the door of the steam-bake device. Then, when it is predicted that the user has opened the door of the steam-bake device, the operating status data of the steam-bake device is obtained as a data basis for determining whether door opening protection is required. It can be understood that the steam-bake device starts working according to a set cooking process, or restarts working after the set cooking process is interrupted.

[0083] The running state data of the steam-bake device may be any state data that can characterize the running process of the steam-bake device. For example, it may be data characterizing the working mode of the steam-bake device, data characterizing the running time of the steam-bake device, or data characterizing the heat accumulation in the cooking cavity of the steam-bake device, such as the temperature data and humidity data of the cooking cavity. In the specific door opening protection judgment process, any one or more of the above data combinations may be selected to implement the door opening protection of the steam-bake device.

[0084] Exemplarily, the operating status data of the steaming and baking device includes at least one of working mode data, operating time data, temperature data in the cooking cavity, and humidity data in the cooking cavity.

[0085] It can be understood that the working mode data and the running time data can be obtained through the internal memory and timer of the controller after the steaming and baking device starts working. Figure 4 As shown, the temperature data in the cooking cavity can be obtained through a temperature sensing package arranged in the cooking cavity, and the humidity data in the cooking cavity can be obtained through a humidity sensor arranged in the cooking cavity.

[0086] Step 204: Perform a safety risk analysis based on the operating status data to determine whether door opening protection needs to be executed.

[0087] Among them, the safety risk analysis can be understood as that after the cooking program of the steaming and baking equipment starts, in response to the user's door opening operation, the controller needs to judge whether the safety opening conditions are met based on the current operating status of the steaming and baking equipment, so as to effectively prevent burns or other thermal injuries caused by improper opening operations and protect user safety.

[0088] Specifically, according to the different data contained in the operating status data, the present embodiment may adopt different safety start conditions to implement the safety risk analysis. For example, in the case where the operating status data contains temperature data, the analysis can be implemented by setting the corresponding temperature threshold as the safety start condition. In the case where the operating status data contains humidity data, the analysis can be implemented by setting the corresponding humidity threshold as the safety start condition. In the case where the operating status data contains both operating mode data and temperature data, the analysis can be implemented by setting the corresponding temperature threshold in each operating mode as the safety start condition. In the case where the operating status data contains running time data, the analysis can be implemented by setting the corresponding running time threshold as the safety start condition.

[0089] Furthermore, the corresponding safety opening condition can be determined according to the operation status data, and whether the door opening protection needs to be performed is determined based on whether the safety opening condition is met. That is, if the operation status data does not meet the safety opening condition, it is determined that the door opening protection needs to be performed; and if the operation status data meets the safety opening condition, it is determined that the door opening protection does not need to be performed.

[0090] Step 206: When it is determined that the door opening protection does not need to be performed, control the steaming and baking device to perform the door opening action in response to the door opening operation.

[0091] Specifically, it is determined that there is no need to perform door opening protection, which means that opening the door at this time will not cause scalding or other thermal damage, and will not cause harm to the user. Then, if it is determined that there is no need to perform door opening protection, the steaming and baking device can be controlled to perform a door opening action in response to the door body opening operation. The door opening action is performed, that is, the door body is manually or automatically rotated around the cabinet body to display the cooking cavity to the outside through the opening.

[0092] It can be understood that when it is predicted that the user will open the door, it may only be judged that the user has the intention to open the door. For example, when the proximity sensor detects the user's approach to the device, the controller can immediately enter the above-mentioned operation status data acquisition and safety risk analysis process to implement a preliminary assessment of the door opening protection. The controller can quickly call the real-time operation status data for safety risk analysis to evaluate whether the door opening protection needs to be executed when the cooking chamber is opened in the current state. Furthermore, when the pressure sensor or release sensor detects the pressure or touch action applied by the user to the door, the user's clear intention to open the door can be identified, and the controller can then respond to the door opening operation.

[0093] Step 208: When it is determined that the door opening protection needs to be executed, the steaming and baking equipment is controlled to execute the door opening protection action.

[0094] Specifically, if it is determined that the door opening protection needs to be executed, it means that it is an inappropriate door opening time point, and forcibly opening the door will cause burns or other thermal damage, causing harm to the user. Then, if it is determined that the door opening protection needs to be executed, the steaming and baking device needs to be controlled to execute the door opening protection action.

[0095] For example, controlling the steaming and baking device to perform the door opening protection action may be to lock the door body for protection, or to start the heat dissipation device to quickly switch the steaming and baking device to a safe state before performing the door opening action, or to perform the door opening action in a way that will not cause harm to the user, or to output interactive information to make the user stay away from the device before performing the door opening action, or to output a waiting reminder message until entering a safe state before performing the door opening action. It can be understood that the purpose of performing the door opening protection action is to protect the user from being harmed by the door opening action, and any method that can prevent the user from being harmed falls within the protection scope of performing the door opening protection action.

[0096] In an exemplary embodiment, when it is determined that door opening protection needs to be performed, the steaming and baking device is controlled to perform the door opening protection action, including: when it is determined that door opening protection needs to be performed, the door body of the steaming and baking device is locked and the heat dissipation device is started.

[0097] Specifically, the door of the steaming and baking device is locked, that is, the door cannot be opened by the user through any structure such as mechanical or magnetic attraction. This locking mechanism can provide the most direct safety protection measure for users, directly preventing users from opening the door in a dangerous state and causing the risk of burns caused by hot steam, hot air or high-temperature food.

[0098] Furthermore, in order to ensure user experience, the steaming and baking equipment can be controlled to start the heat dissipation device to quickly switch the cooking cavity to a safe state, so as to complete the user's door opening operation and open the door. The heat dissipation device may specifically include but is not limited to a fan, a dehumidification device, a drying device and other devices, which are specifically used to enhance the air circulation inside the cooking cavity, or introduce dry air, to help reduce the temperature and humidity inside the cooking cavity, and accelerate the safe state of opening the door.

[0099] In an exemplary embodiment, when it is determined that door opening protection needs to be performed, the steaming and baking device is controlled to perform the door opening protection action, and it also includes: when it is determined that door opening protection needs to be performed, the interactive device of the steaming and baking device is controlled to output a waiting reminder message.

[0100] It is understandable that in order to further enhance the user experience and ensure user safety, the controller can also control the interactive device of the steaming and baking device to output waiting reminder information. Specifically, the waiting reminder information can be used to remind the user that the current device is in a state that is not suitable for opening the door, and can also be used to remind the user of the estimated waiting time and safe operation suggestion information, and can also be used to convey the current operating status of the device to the user, such as the temperature and humidity status, so that the user is aware of the current unsafe time point for opening the door.

[0101] The waiting reminder information can be combined with sound or visual reminder, and the type of the interactive device is not unique, and can be a sound output device or a display device, etc. For example, the interactive device can be a speaker or a buzzer, or an indicator light or a display screen, etc.

[0102] In this embodiment, the door opening protection action is intended to prevent accidents through actual physical restrictions, rather than relying solely on user reactions or reminder information. This strategy plays a vital role in ensuring user safety and preventing injuries caused by leakage of high-temperature steam or hot air inside the cooking chamber of the steam-bake device.

[0103] The control method of the steam-bake device described above acquires the operation status data of the steam-bake device when predicting that the user will open the door of the steam-bake device, and performs safety risk analysis based on the operation status data to determine whether it is necessary to perform door opening protection. When it is determined that it is not necessary to perform door opening protection, the steam-bake device is controlled to perform the door opening action in response to the door opening operation; when it is determined that it is necessary to perform door opening protection, the steam-bake device is controlled to perform the door opening protection action to avoid the safety risk of high-temperature gas blowing in the face when the user opens the door of the device during use of the steam-bake device, thereby preventing the user from being scalded by steam or high-temperature burns.

[0104] In an exemplary embodiment, Figure 5 As shown, step 204 includes the following steps 302 to 306, wherein:

[0105] Step 302: Determine a target safety start condition according to the operating status data.

[0106] Specifically, the controller can pre-set the corresponding safety start-up conditions based on the specific content of the operating status data that may be obtained. Then, in the actual safety risk analysis process, the corresponding safety start-up conditions can be matched and determined as the target safety start-up conditions according to the real-time operating status data called. It can be understood that when the operating status data contains multiple operating status data, there are also multiple corresponding target safety start-up conditions.

[0107] For example, when the real-time operating status data called contains temperature data, its preset temperature threshold can be determined as the target safe starting condition; when the real-time operating status data called contains humidity data, its preset humidity threshold can be determined as the target safe starting condition; when the real-time operating status data called contains both working mode data and temperature data, the corresponding temperature thresholds in each preset working mode can be determined as the target safe starting condition; when the real-time operating status data called contains operating duration data, the preset operating duration threshold can be determined as the target safe starting condition.

[0108] Step 304: When the operating status data meets the target safety opening condition, it is determined that there is no need to perform door opening protection.

[0109] It can be understood that the operating status data meets the target safe opening conditions, that is, all the acquired operating status data meet their corresponding target safe opening conditions, indicating that opening the door at this time will not cause burns or other thermal damage, and will not cause harm to the user, and thus it is determined that there is no need to perform door opening protection.

[0110] Exemplarily, when the real-time operating status data called includes temperature data, the operating status data satisfies the target safe start-up condition, which may be that the temperature data is less than a preset temperature threshold; when the real-time operating status data called includes humidity data, the operating status data satisfies the target safe start-up condition, which may be that the humidity data is less than a preset humidity threshold; when the real-time operating status data called includes both working mode data and temperature data, the operating status data satisfies the target safe start-up condition, which may be that the temperature data is less than the corresponding temperature threshold under each preset working mode; when the real-time operating status data called includes running time data, the operating status data satisfies the target safe start-up condition, which may be that the running time data is less than the preset running time threshold.

[0111] Among them, the above-mentioned method of judging whether the temperature data and humidity data are less than their corresponding preset thresholds can be that the temperature and humidity data collected continuously within a preset time period are all less than their corresponding preset thresholds, so as to ensure the accuracy of the security risk analysis as much as possible, and thus ensure user safety.

[0112] Step 306: When the operating status data does not meet the target safety opening condition, it is determined that door opening protection needs to be performed.

[0113] It can be understood that the operating status data does not meet the target safe opening conditions, that is, there are situations in all the acquired operating status data that do not meet the corresponding target safe opening conditions, indicating that opening the door at this time will cause burns or other thermal damage, causing harm to the user, and then determining that door opening protection needs to be executed.

[0114] In addition, under different operating status data, the method for judging whether the operating status data does not meet the target safety start-up condition can refer to the example description of the operating status data meeting the target safety start-up condition in step 304, which can be the opposite, and will not be repeated here.

[0115] In this embodiment, by obtaining various operating status data during the operation of the steaming and baking equipment and pre-setting the safe opening conditions for various operating status data, it is possible to intelligently determine whether door opening protection needs to be executed under different working conditions, thereby improving the accuracy and comprehensiveness of the judgment and effectively avoiding injuries to users.

[0116] In an exemplary embodiment, Figure 6 As shown, step 302 includes step 402: when the operating status data includes temperature data in the cooking cavity, determining the target safety opening condition is that the temperature data in the cooking cavity is less than a preset temperature threshold.

[0117] It can be understood that the temperature data in the cooking cavity represents the temperature conditions in the cooking cavity. For steaming and baking equipment, the temperature data is the key data for determining whether opening the door will cause high temperature burns to the user.

[0118] Specifically, when the operating status data includes the temperature data in the cooking cavity, the corresponding target safety opening condition can be determined according to the matching of the temperature data in the cooking cavity. In this embodiment, the safety opening condition corresponding to the temperature data in the cooking cavity is set to that the temperature data in the cooking cavity is less than a preset temperature threshold.

[0119] It can be understood that the preset temperature threshold is a safe temperature threshold that should not be exceeded inside the cooking cavity when the steaming and baking device performs the door opening action. When the temperature data inside the cooking cavity is greater than or equal to the preset temperature threshold, the steaming and baking device performs the door opening action, and the outside cold air instantly rushes into the cooking cavity, causing the cold air to expand when it encounters heat and rush open the door body, which may cause the user to be burned by the oncoming high-temperature gas. In this embodiment, based on preliminary tests, a safe temperature threshold that will not cause high-temperature gas to rush open the door body can be tested and used as the preset temperature threshold in the safe opening condition. The specific value of the preset temperature threshold can be designed according to the actual equipment situation and is not limited. For example, the preset temperature threshold in the safe opening condition of a certain steaming and baking device can be set to 50°C.

[0120] In an exemplary embodiment, please continue to refer to Figure 6 , step 302 includes step 404: when the operating status data includes the operating mode data and the temperature data in the cooking cavity, determining the target safety opening condition is that the temperature data in the cooking cavity is less than a preset temperature threshold corresponding to the operating mode type.

[0121] It is understandable that general steaming and baking equipment has multiple working modes. For example, in the embodiment of the present application, the working mode types of the steaming and baking equipment may include steaming mode, baking mode and steaming and baking mode. Among them, in the steaming mode, high-temperature steam can be output to cook food, and in the baking mode, high-temperature baking can be used to remove moisture from the surface of the food for cooking. The steaming and baking mode is a combination of the steaming mode and the baking mode, which can be steaming and baking in the cooking cavity at the same time, or steaming first and then baking, or baking first and then steaming.

[0122] Specifically, due to the significant difference in temperature inside the cooking cavity under different working modes, the safety impact on the user's door opening operation under different working modes is also different. For example, the temperature data inside the cooking cavity in the general baking mode is much higher than the temperature data inside the cooking cavity in the steaming mode. In the baking mode, the mode target temperature may need to be set to 200°C to bake meat, while in the steaming mode, the mode target temperature can be set to the ideal temperature of about 100°C for steaming vegetables.

[0123] Furthermore, a preset temperature threshold corresponding to each working mode type can be set as a safe start condition under the working mode type. In the case where the operating status data includes working mode data and temperature data in the cooking cavity, the target safe start condition is matched and determined based on the working mode type corresponding to the working mode data. Of course, since the operating status data is the temperature data in the cooking cavity, the target safe start condition is that the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the working mode type.

[0124] For example, Figure 7 As shown, step 404 includes the following steps 502 to 506, wherein:

[0125] Step 502: When the operating status data includes working mode data and cooking cavity temperature data, and the working mode data is the steaming mode, determine that the target safety opening condition is that the cooking cavity temperature data is less than a preset temperature threshold corresponding to the steaming mode.

[0126] Specifically, the steam-bake device can be operated in the steam mode in advance, and a test can be conducted to obtain a safe temperature threshold that will not cause high-temperature gas to rush open the door body, which can be used as the preset temperature threshold corresponding to the steam mode. Then, when the working mode data is the steam mode, the target safe opening condition is matched and determined according to the working mode type of the steam mode, that is, the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the steam mode.

[0127] It can be understood that when the temperature data in the cooking cavity is lower than the preset temperature threshold corresponding to the steaming mode, it is determined that there is no need to perform door opening protection; when the temperature data in the cooking cavity is greater than or equal to the preset temperature threshold corresponding to the steaming mode, it is determined that door opening protection needs to be performed.

[0128] Step 504: When the operating status data includes the operating mode data and the temperature data in the cooking cavity, and the operating mode data is the roasting mode, the target safety opening condition is determined as the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the roasting mode.

[0129] Specifically, the steam-bake device can be operated in the baking mode in advance, and a test can be conducted to obtain a safe temperature threshold that will not cause high-temperature gas to rush open the door body, which can be used as the preset temperature threshold corresponding to the baking mode. Then, when the working mode data is the baking mode, the target safe opening condition is matched and determined according to the working mode type of the baking mode, that is, the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the baking mode.

[0130] It can be understood that when the temperature data in the cooking cavity is lower than the preset temperature threshold corresponding to the baking mode, it is determined that there is no need to perform door opening protection; when the temperature data in the cooking cavity is greater than or equal to the preset temperature threshold corresponding to the baking mode, it is determined that door opening protection needs to be performed.

[0131] Exemplarily, the preset temperature threshold corresponding to the roasting mode may also be set based on the mode target temperature and the first preset temperature difference.

[0132] Specifically, the mode target temperature is the target temperature set by the user in the cooking process. The preset temperature threshold corresponding to the baking mode can be set to a temperature value that is lower than the mode target temperature set by the user by a first preset temperature difference. The value of the first preset temperature difference is not fixed and can be determined according to the technical requirements of the actual steaming and baking equipment. For example, in this embodiment, the first preset temperature difference can be set to 10°C.

[0133] It can be understood that in the baking mode for baking alone, not only the fixed safety temperature threshold can be used as the condition for judging the door opening protection, but the preset temperature threshold can be dynamically set according to the mode target temperature set by the user and the preset temperature difference, that is, in any cooking process, the preset temperature threshold is lower than the mode target temperature by the preset temperature difference, which can ensure that no harm to the user will occur in any cooking process.

[0134] Step 506: When the operating status data includes the operating mode data and the temperature data in the cooking cavity, and the operating mode data is the steaming and baking mode, determine that the target safety opening condition is that the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the steaming and baking mode.

[0135] Specifically, the steam-bake device can be operated in the steam-bake mode in advance, and a test can be conducted to obtain a safe temperature threshold that will not cause high-temperature gas to rush open the door body, which can be used as the preset temperature threshold corresponding to the steam-bake mode. Then, when the working mode data is the steam-bake mode, the target safe opening condition is matched and determined according to the working mode type of the steam-bake mode, that is, the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the steam-bake mode.

[0136] It can be understood that when the temperature data in the cooking cavity is lower than the preset temperature threshold corresponding to the steam-bake mode, it is determined that there is no need to execute the door opening protection; when the temperature data in the cooking cavity is greater than or equal to the preset temperature threshold corresponding to the steam-bake mode, it is determined that the door opening protection needs to be executed.

[0137] In this embodiment, by combining the working mode data with the temperature data in the cooking cavity, the safety of the user's door opening operation can be intelligently judged, and the intelligence level and user experience of the steaming and baking equipment can be improved. This door opening protection logic control strategy based on the working mode data and the temperature data in the cooking cavity can maximize the safety of the user during the operation while ensuring the cooking effect. Through continuous optimization, the accuracy and flexibility of the judgment can be further improved, providing users with a more reliable and intelligent door opening protection service.

[0138] Exemplarily, when the cooking process of the steaming and baking mode is steaming first and then baking or baking first and then steaming, the steaming and baking equipment needs to switch the mode stages between the steaming mode and the baking mode, and then the preset temperature thresholds corresponding to the two mode stages can be set to different preset temperature thresholds to avoid the potential danger to the user caused by the sudden temperature change caused by the mode stage switching, especially when switching from the baking mode (higher temperature) to the steaming mode (relatively lower temperature).

[0139] Specifically, the preset temperature threshold corresponding to the latter mode stage may be set to a higher temperature value than the preset temperature threshold corresponding to the previous mode stage to ensure that the device can respond quickly and perform door opening protection even under higher temperature conditions.

[0140] For example, the mode before mode conversion is in baking mode and the mode target temperature is 200℃. Under this mode, the surface of the food is forming a satisfactory golden and crispy color. The preset temperature threshold in this mode stage can be 50℃. After running for a period of time, the cooking process needs to switch from baking mode to steaming mode. At this time, the controller slows down or stops the power supply to the baking heater and increases the steam generation / steam injection to quickly reduce the internal temperature. In this mode stage, the preset temperature threshold needs to be switched to 70~80℃ to avoid the potential danger to the user caused by the rapid temperature change caused by the mode stage switching.

[0141] In an exemplary embodiment, Figure 8 As shown, step 502 includes the following steps 602 to 604, wherein:

[0142] Step 602: When the operating status data includes working mode data and cooking cavity temperature data, the working mode data is steaming mode, and the mode target temperature is greater than or equal to the high temperature threshold, determine that the target safety opening condition is that the cooking cavity temperature data is less than the preset temperature threshold corresponding to the first steaming mode.

[0143] First, in steam mode, the cooking chamber is filled with steam, and steam has higher energy at higher temperatures. If the user opens the door in steam mode, especially when the pressure inside the cooking chamber is high, the overheated steam will expand and overflow rapidly, which may cause burns and other injuries to the user. When the temperature data inside the cooking chamber exceeds the high temperature threshold, the temperature and pressure of the steam inside the cooking chamber may reach more dangerous levels. Therefore, when the mode target temperature is greater than or equal to the high temperature threshold, more stringent safety opening conditions need to be set to ensure user safety.

[0144] Secondly, when the steam-bake device is in steam mode, a high temperature and high humidity environment will be maintained in the cooking cavity to achieve the best steaming effect. If the door is opened frequently during the cooking process in the steam mode, especially when the mode target temperature is greater than or equal to the high temperature threshold, the temperature and humidity inside the cooking cavity will drop rapidly and require more energy and time to recover, which will greatly reduce the energy efficiency of the steam-bake device and increase energy consumption. Furthermore, in order to optimize energy use, when the mode target temperature is greater than or equal to the high temperature threshold, more stringent safety opening conditions need to be set to reduce energy efficiency losses caused by frequent door openings.

[0145] The value of the high temperature threshold is not fixed and can be determined according to the technical requirements of the actual steaming and baking equipment. For example, in this embodiment, the high temperature threshold can be set to 80°C.

[0146] Specifically, when the steaming and baking device is working in the steaming mode and the mode target temperature is greater than or equal to the high temperature threshold, a test can be conducted in advance to obtain a safe temperature threshold that will not cause high temperature gas to rush open the door body, which is used as the preset temperature threshold corresponding to the first steaming mode. Then, when the working mode data is the steaming mode and the mode target temperature is greater than or equal to the high temperature threshold, the target safety opening condition is matched and determined according to the working mode type of the first steaming mode, that is, the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the first steaming mode.

[0147] It can be understood that when the temperature data in the cooking cavity is lower than the preset temperature threshold corresponding to the first steaming mode, it is determined that there is no need to perform door opening protection; when the temperature data in the cooking cavity is greater than or equal to the preset temperature threshold corresponding to the first steaming mode, it is determined that door opening protection needs to be performed.

[0148] In an exemplary embodiment, the preset temperature threshold corresponding to the first steaming mode is set based on the mode target temperature and the second preset temperature difference.

[0149] Similarly, the mode target temperature is the target temperature set by the user in the cooking process. The preset temperature threshold corresponding to the first steaming mode can be a temperature value set to be lower than the mode target temperature set by the user by a second preset temperature difference. The value of the second preset temperature difference is not fixed and can be determined according to the technical requirements of the actual steaming and baking equipment. For example, in this embodiment, the second preset temperature difference can be set to 20°C.

[0150] In this embodiment, the preset temperature threshold is dynamically set according to the mode target temperature set by the user and the preset temperature difference. That is, in any cooking process, the preset temperature threshold is lower than the mode target temperature by the preset temperature difference, which can ensure that no harm to the user will occur in any cooking process.

[0151] Step 604: When the operating status data includes working mode data and cooking cavity temperature data, the working mode data is steaming mode, and the mode target temperature is less than the high temperature threshold, determine that the target safety opening condition is that the cooking cavity temperature data is less than the preset temperature threshold corresponding to the second steaming mode.

[0152] Specifically, when the steaming and baking device is working in the steaming mode and the mode target temperature is less than the high temperature threshold, a test can be conducted in advance to obtain a safe temperature threshold that will not cause high temperature gas to rush open the door body, which is used as the preset temperature threshold corresponding to the second steaming mode. Furthermore, when the working mode data is the steaming mode and the mode target temperature is less than the high temperature threshold, the target safety opening condition is matched and determined according to the working mode type of the second steaming mode, that is, the temperature data in the cooking cavity is less than the preset temperature threshold corresponding to the second steaming mode. Among them, the value of the preset temperature threshold corresponding to the second steaming mode is not fixed, and can be determined according to the technical requirements of the actual steaming and baking device. For example, in this embodiment, it can be set to 60°C.

[0153] It can be understood that when the temperature data in the cooking cavity is lower than the preset temperature threshold corresponding to the second steaming mode, it is determined that there is no need to perform door opening protection; when the temperature data in the cooking cavity is greater than or equal to the preset temperature threshold corresponding to the second steaming mode, it is determined that door opening protection needs to be performed.

[0154] In an exemplary embodiment, please continue to refer to Figure 6 , step 302 includes step 406: when the operating status data includes humidity data in the cooking cavity, determining that the target safety opening condition is that the humidity data in the cooking cavity is less than a preset humidity threshold.

[0155] It is understandable that in the steaming mode of the steam-bake equipment, the inside of the cooking cavity will not only generate high temperature due to steam heating, but also form a high humidity environment. The high humidity environment inside the cooking cavity has a positive effect on improving the taste of food and retaining nutrition, but it also brings safety impacts. When the user cooks in the steaming mode and opens the door, the high-temperature water vapor formed by the combination of high humidity and high temperature inside will pose a great potential threat to the user. Therefore, the humidity data in the cooking cavity needs to be included as a key parameter in the safe opening conditions of the door, which is crucial to achieving door opening protection.

[0156] Specifically, when the operating status data includes the humidity data in the cooking cavity, the corresponding target safety opening condition can be determined according to the matching of the humidity data in the cooking cavity. In this embodiment, the safety opening condition corresponding to the humidity data in the cooking cavity is set to that the humidity data in the cooking cavity is less than a preset humidity threshold.

[0157] It can be understood that the preset humidity threshold is a safe humidity threshold that should not be exceeded inside the cooking cavity when the steaming and baking device performs the door opening action. When the humidity data inside the cooking cavity is greater than or equal to the preset humidity threshold, the steaming and baking device performs the door opening action, and the outside cold air instantly rushes into the cooking cavity, causing the cold air to expand when it encounters heat and rush open the door body, which may cause the user to be burned by the oncoming high-temperature steam. In this embodiment, based on a preliminary test, a safe humidity threshold that will not cause high-temperature steam to rush open the door body can be tested and obtained as the preset humidity threshold in the safe opening condition. This application does not limit the specific value of the preset humidity threshold.

[0158] In an exemplary embodiment, please continue to refer to Figure 6 , step 302 includes step 408: when the running status data includes the working mode data and the running time data, determining the target safety start condition as the running time data being less than a preset running time threshold corresponding to the working mode type.

[0159] It can be understood that during the cooking process of the steaming and baking equipment, the running time data can be used to reflect the state of heat energy accumulation inside the cooking cavity. That is, as the cooking time increases, the heat energy inside the cooking cavity will continue to accumulate and reach a certain temperature and heat energy level, which is also directly related to the safety of the user's door opening operation. If the door is suddenly opened when the heat energy inside the cooking cavity is extremely high, high-temperature steam or hot air will leak rapidly, causing potential scalding or burn risks to the user. Therefore, it is very necessary to incorporate the running time data into the logic control for executing door opening protection.

[0160] Specifically, it is obvious that the heat accumulation rate inside the cooking cavity is different under different working modes. For example, in steaming mode, it may take longer for the cooking cavity to accumulate heat, while in baking mode, the heat accumulation rate is faster. Therefore, for each working mode type, a corresponding preset operation time threshold can be set as a safe start condition.

[0161] Furthermore, when the operation status data includes the operation mode data and the operation duration data, the corresponding target safety start condition can be matched and determined based on the operation mode type corresponding to the operation mode data. In this embodiment, the safety start condition corresponding to the operation duration data is set to the operation duration data being less than the preset operation duration threshold corresponding to the operation mode type.

[0162] In an exemplary embodiment, the preset operation time threshold of each operating mode type is set according to the heat energy accumulation rate corresponding to the operating mode type and the preset temperature threshold.

[0163] It can be understood that the preset temperature threshold can be a preset temperature threshold corresponding to each working mode type, that is, the time required to reach the preset temperature threshold can be estimated based on the heat energy accumulation rate under the working mode type, and then set as the preset operating time threshold under the working mode type.

[0164] For example, after the controller controls the steaming and baking device to start a cooking process, the internal timer can be started to measure the running time. When the running time reaches a preset running time threshold, the controller can automatically perform the operation data acquisition and safety risk analysis process to determine whether the door opening protection needs to be executed at this moment. If so, it indicates that the heat energy accumulation state inside the cooking cavity has reached a high heat energy level, and the user's door opening operation is risky. Therefore, before the cooking process ends, the user's door opening operation must perform door opening protection to ensure the user's safety.

[0165] In this embodiment, when the operating time reaches a preset operating time threshold, a safety risk analysis and door opening protection judgment can be performed in advance, thereby omitting the subsequent real-time data acquisition and judgment process, improving the risk response speed, and more quickly preventing the user from opening the door to ensure the user's safety.

[0166] In an exemplary embodiment, Fig. 9 As shown, the control method of the steaming and baking device also includes the following steps 702 to 704:

[0167] Step 702: Analyze the operating status data to obtain actual thermal energy accumulation data.

[0168] Specifically, during the cooking process of the steaming and baking device, the controller can obtain the current operating status data in real time, such as the temperature data and humidity data in the cooking cavity, etc. And according to the above temperature and humidity data, the actual heat energy accumulation data in the cooking cavity is analyzed.

[0169] Among them, the method of analyzing and obtaining the actual thermal energy accumulation data in the cooking cavity can be obtained according to the thermal energy calculation method well known to those skilled in the art, and will not be described in detail in the embodiments of the present application.

[0170] Step 704: Correct the heat energy accumulation rate corresponding to the working mode type based on the actual heat energy accumulation data.

[0171] Specifically, after analyzing and obtaining the actual heat energy accumulation data in the cooking cavity, the actual heat energy accumulation rate can be calculated based on the actual data and the corresponding operation time data. Furthermore, if the calculated heat energy accumulation rate is inconsistent with the original heat energy accumulation rate stored in the controller, it can be corrected to the heat energy accumulation rate corresponding to the working mode type. This ensures the accurate setting of the preset operation time threshold, thereby ensuring user safety.

[0172] In this embodiment, in a certain working mode type, such as the baking mode, the heat energy accumulation state in the cooking chamber is always slightly lower than the standard, and then the controller can adjust the preset operating time threshold according to the corrected heat energy accumulation rate to provide a more personalized protection strategy to ensure that the temperature when the user performs the door opening operation is more in line with actual usage.

[0173] In an exemplary embodiment, the control method of the steaming and baking device further includes: performing a usage habit analysis based on the operation status data and the user behavior status data, obtaining the user habit data, and controlling the operation of the steaming and baking device based on the user habit data.

[0174] Specifically, user habit data can characterize the user's usage habits of steaming and baking equipment. For example, it can characterize the types of working modes commonly used by users, as well as the time information when users often use steaming and baking equipment, that is, users often use the steaming mode in the morning to prepare breakfast. It can also characterize the user's preferred door opening operation behavior, such as the user prefers to open the door to check the ingredients about 2 minutes before the end of cooking, and may also prefer "quick door opening check", and may frequently open and close the door to observe the status of the food, while there may be other users who may pay more attention to maintaining the continuity of the cooking process and rarely open the door.

[0175] Furthermore, the controller can perform usage habit analysis based on the operation status data and the user behavior status data to obtain user habit data to control the operation of the steaming and baking equipment.

[0176] In this embodiment, the controller can learn and analyze the user's usage habits, and predict various user behaviors during the user's use of the steaming and baking device to enhance the user experience. For example, for users who prefer to open the door to check the ingredients about 2 minutes before the end of cooking, the temperature threshold of the door opening protection will be pre-adjusted to a closer but still safe preset temperature threshold before reaching this time node, reducing unnecessary cooling waiting time. Based on the learning and analysis of user usage habits, the rapid response mechanism of door opening protection and restart heating can be dynamically adjusted to adapt to the behavior of different users. The way to perform door opening protection can be adjusted according to the frequency of user door opening. For users who open the door frequently, the device can optimize the cooling rate and heating restart efficiency to shorten the waiting time. For users who open the door less frequently, the focus can be on the uniformity of the new heating to ensure that the food can be heated more evenly when the door is closed again after opening.

[0177] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0178] Based on the same inventive concept, the embodiment of the present application also provides a control device for a steaming and baking device for implementing the control method for the steaming and baking device involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of the control device for one or more steaming and baking devices provided below can refer to the limitations of the control method for the steaming and baking device above, and will not be repeated here.

[0179] In an exemplary embodiment, Fig.10 As shown, a control device for steaming and baking equipment is provided, comprising: an acquisition module 101, an analysis module 102 and a control module 103, wherein:

[0180] An acquisition module 101 is used to acquire the operation status data of the steaming and baking device when it is predicted that the user has opened the door of the steaming and baking device;
