[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] In order to facilitate the understanding of this embodiment, the application scenarios and design concepts of the embodiments of the present application are briefly introduced.

[0049] Existing cooking devices usually stop running immediately when an operation anomaly is detected, forcibly terminating the operation, and incomplete cooking will cause food waste; or when an operation anomaly is detected, a prompt is returned to wait for a user response. If the user does not respond for a long time, the food may be overcooked, resulting in a poor user experience.

[0050] Based on this, the embodiment of the present application provides a control method, device and cooking device for a cooking device. The control method of the cooking device is applied to a control mechanism in a control system of the cooking device, and the control system of the cooking device also includes a mobile terminal, which is connected to the control mechanism for communication. The control mechanism includes a database, which stores multiple operating modes and historical data corresponding to each operating mode, and the historical data includes the historical preheating time, historical temperature rise threshold, historical cooking parameters, etc. corresponding to each heating mechanism.

[0051] Example 1

[0052] The present application provides a control method for a cooking device, combining Figure 1 As shown, the method includes:

[0053] S110, for each heating mechanism in the cooking device, obtaining the current preheating time and the accumulated working time of the heating mechanism in the current operating mode.

[0054] S120, obtaining a specified number of historical preheating durations close to the current time in a database, wherein the historical preheating durations correspond to the current operating mode and the heating mechanism.

[0055] S130, determining whether the current preheating time and a specified number of historical preheating time are both greater than a preheating time threshold corresponding to the current operating mode, and / or whether the accumulated working time is greater than a working time threshold.

[0056] If so, execute step S140.

[0057] S140, after the cooking device reaches the target temperature, a prompt message for repairing or replacing the heating mechanism is sent to the cooking device and a mobile terminal that is communicatively connected to the cooking device.

[0058] The control method of the cooking device provided by the present application obtains the current preheating time and cumulative working time of each heating mechanism in the current operating mode during the operation of the cooking device, and then obtains the historical preheating time of the heating mechanism in the same mode (i.e., the current operating mode) in the database, and determines whether the heating mechanism is abnormal through the first comparison relationship between the multiple preheating times of the heating mechanism in the current operating mode and the preheating time threshold, and the second comparison relationship between the cumulative working time and the working time threshold, and sends a prompt message to the cooking device and the mobile terminal after the current operating mode is completed. In this way, the working state of the heating mechanism in the operating mode is determined by the two parameters of preheating time and cumulative working time, and the abnormality of the heating mechanism is predicted in time, and the customer is reminded after the cooking is completed, thereby reducing or eliminating the situation where the cooking device suddenly fails and cannot be used, incomplete cooking or overcooking.

[0059] In combination with the first aspect, the control mechanism includes a database storing a one-to-one correspondence between a plurality of operating modes and operating powers of a plurality of heating mechanisms;

[0060] Before step S110, the method further includes:

[0061] S010, in response to a start-up instruction, starting the heating mechanism and acquiring the operation mode information in the start-up instruction.

[0062] First, the user starts the cooking device, and generates a start instruction according to the name of the dish entered by the user, the execution mode selected, the execution mode selected by rotating the button, etc. The operation mode information of this cooking can be determined according to the start instruction, and the operation mode information at least includes: heating temperature, heating time. It can be understood that the operation mode can also include: specific cooking methods such as: baking, frying, steaming, etc. For example, the operation mode this time is determined to be: baking, 180℃, 22min. With the updating of cooking equipment technology, in order to meet actual use needs and improve product competitiveness, cooking equipment has more and more operation modes, such as nutritional steaming, surging steaming, wind baking, strong grilling and air frying. Based on different operation modes, cooking equipment can perform cooking processing on ingredients with different cooking types and different cooking parameters.

[0063] S020: Determine the operation parameters corresponding to the operation mode information according to the preset corresponding relationship.

[0064] S030, controlling the heating mechanism to operate according to the operating parameters.

[0065] Based on the preset corresponding relationship, each operation mode corresponds to the operation parameters of the heating mechanism, and the operation parameters at least include the operation power, target temperature value, and set preheating time of the heating mechanism. The operation of the heating mechanism is controlled according to the operation parameters. It can be understood that as the cumulative working time increases, the heating mechanism will have performance degradation, so the preheating time of the heating mechanism to heat to the same target temperature value will be extended as the performance decays. Therefore, the performance degradation of the heating mechanism can be predicted by the extension degree of the preheating time of the heating mechanism in the same operation mode, so as to remind the user in time.

[0066] It can be understood that the cooking device provided in this embodiment records and stores the operation time of each operation mode used, the preheating time of each heating mechanism in the operation mode, the cumulative working time of each heating mechanism, the number of maintenance times, etc. Preferably, in this embodiment, a power-off storage chip is used to store the above data, so that the memory data is not lost when the device is powered off, so as to facilitate data storage continuity and improve the accuracy of prediction.

[0067] In response to the data acquisition request sent by the mobile terminal, the corresponding data is returned to the mobile terminal, so that the recorded data can be obtained by the mobile terminal. It can be understood that the recorded data can also be actively sent to the mobile terminal by the controller.

[0068] Before step S130, the following steps are also included:

[0069] S121, obtaining a standard heating time corresponding to the operation mode information and an initial temperature and a target temperature in a furnace of the cooking device.

[0070] S122: Calculate a preheating time threshold corresponding to the operation mode information according to the standard heating time, the initial temperature and the target temperature.

[0071] In this embodiment, due to the different target temperatures required for cooking and the diversity of operating modes, different target temperatures to be achieved in the same operating mode have different corresponding preheating time thresholds. Therefore, before comparing the current preset time with the preheating time threshold, the preheating time threshold corresponding to the operating mode is first calculated.

[0072] Specifically, step S122 includes:

[0073] S1220, if te1 <T1,tsi=2×[(te1-te0)×tSi1÷T1]。

[0074] S1221, if T1≤te1 <T2,tsi=2×[(T1-te0)×tSi1÷T1+(te1-T1)×tSi2÷T1]。

[0075] S1222, if T2≤te1≤T3, tsi=2×[(T1-te0)×tSi1÷T1+tSi2+(te1-T2)×tSi3÷90].

[0076] Among them, te1 is the target temperature, te0 is the initial temperature, tsi is the preheating time threshold corresponding to the i-th operating mode, T1 is the first temperature threshold, T2 is the second temperature threshold, T3 is the third temperature threshold, T1<T2<T3, tSi1 is the standard heating time from 0℃ to T1 in the cold state corresponding to the i-th operating mode, tSi2 is the standard heating time from T1 to T2 in the cold state corresponding to the i-th operating mode, and tSi3 is the standard heating time from T2 to T3 in the cold state corresponding to the i-th operating mode.

[0077] In this embodiment, T1 = 80°C, T2 = 160°C, T3 = 250°C, wherein 0°C < te0 < 50°C, te1 ≤ 250°C.

[0078] It can be understood that when the multiple preheating times corresponding to the current operating mode (the current preheating time and multiple historical preheating times) are all greater than the preheating time threshold, it can be predicted that the heating mechanism performance will decay. After the current operating mode ends (that is, the target temperature is reached), a prompt message indicating that the heating mechanism performance has decayed and maintenance is recommended is returned.

[0079] At the same time, the accumulated working time of each heating mechanism is compared with the corresponding working time threshold of the heating mechanism in the database (that is, the effective life of the heating mechanism). If the working time threshold corresponding to the heating mechanism is exceeded, a prompt message is returned after the current operating mode ends, indicating that the heating mechanism has reached its service life and replacement is recommended.

[0080] In combination with step S150 of the first aspect, after the step of responding to the shutdown instruction, controlling the cooking device to stop running and storing the operating parameters corresponding to the current operating mode in the database, the method further includes:

[0081] S151, sending a request to the mobile terminal for obtaining cooking effect evaluation information.

[0082] S152, in response to the cooking effect evaluation information transmitted by the user, identifying the cooking effect evaluation information to obtain an evaluation result.

[0083] S153, if the evaluation result indicates that the cooking effect is good, the cooking parameters of this cooking are transmitted to the cooking database of the mobile terminal and stored in the cloud; the cloud is connected to the multiple mobile terminals for communication.

[0084] After cooking is completed, cooking effect evaluation information is pushed to the mobile terminal to collect the user's evaluation of the cooking effect, and the cooking effect evaluation information transmitted by the user is recognized (this recognition method is not limited to the semantic recognition method for text and voice information, and also includes the image recognition method for uploaded images, such as by recognizing the text in the image or using filters based on the image). When the evaluation result indicates that the cooking effect is good, the cooking parameters are stored in the cooking database of the mobile terminal and transmitted to the cloud to update the cooking parameters in the cloud database.

[0085] The cooking effect evaluation information transmitted by the user may be in various forms, such as voice data, text data, and image data.

[0086] In combination with the first aspect, step S152 further includes S154, if the evaluation result indicates that the cooking effect is unsatisfactory, storing the cooking parameters of this cooking in the database, and transmitting them to the improved database of the mobile terminal.

[0087] In the case that the user is not satisfied with the cooking effect, the cooking parameters are transmitted to the improvement database of the mobile terminal so that the development project can analyze and improve the program settings based on the improvement data.

[0088] After step S152 in the first aspect, the method further includes:

[0089] S155, in response to the dish name and / or cooking picture transmitted by the user, the dish name and / or cooking picture are identified to determine the target dish name.

[0090] S155, establishing a correspondence between the cooking parameters and the target dish name, and transmitting the correspondence to the mobile terminal.

[0091] The cooking parameters include at least: cooking mode, cooking temperature, and cooking method.

[0092] In this embodiment, after the user transmits the dish name and / or cooking picture, a correspondence between the cooking parameters and the target dish name is established and transmitted to the mobile terminal so that the dish can be analyzed and optimized according to the cooking parameters.

[0093] In combination with the first aspect, the method further includes:

[0094] S310, obtaining information of multiple operation modes whose application frequencies are greater than a preset value.

[0095] S320: For each piece of operation mode information, obtain usage suggestion information corresponding to the operation mode information, and obtain cooking parameters corresponding to the operation mode information in a cooking database.

[0096] S330, push usage suggestion information and cooking parameters to the mobile terminal.

[0097] By obtaining information about multiple operating modes that are frequently used in actual applications and uploading them to the cloud, equipment developers can conduct targeted development based on the most popular modes to focus on improving the cooking parameters of recipes related to the operating mode (such as the combination of steaming, frying and baking, the target heating temperature and target working time of each stage, etc.) or expanding the types of recipes. After that, usage suggestion information is generated and the cloud is used to find cooking parameters that are well evaluated by other users after cooking and push them to the mobile terminal, so as to push suggestions to users on how to use this mode efficiently and share other users' successful cooking experiences.

[0098] In combination with the first aspect, S310 and thereafter further include:

[0099] S320, obtaining an associated device corresponding to the cooking device;

[0100] S330, receiving updated cooking parameters sent from the cloud and transmitting the cooking parameters to the associated device.

[0101] By obtaining information on multiple operating modes that are used frequently during actual applications and uploading them to the cloud, equipment R&D personnel can conduct targeted development based on the more popular modes to concentrate on improving the cooking parameters of recipes related to the operating mode (such as multi-stage combinations of steaming, frying and baking, target heating temperatures for each stage, and target working time, etc.) or expanding the types of recipes, receiving updated cooking parameters and recipe categories from the cloud, and sending them to related equipment in a timely manner, so that the cooking performance and functions of the device end can be sustainably upgraded.

[0102] Furthermore, after obtaining the cooking parameters of each device model, the cooking parameters are divided according to the regional information to determine the frequency ranking results of the mode usage of the cooking device of the device model under a certain regional information, and push it to other users in the regional information. In this way, information interaction between devices in a certain region can be achieved, and intelligent upgrades of devices in the region can be achieved. As another feasible method, the mobile terminal receives the cooking effect information fed back by the user, and integrates it based on the collected cooking parameters to optimize the cooking parameters.

[0103] In combination with the first aspect, the method further includes:

[0104] S410, for each heating mechanism, obtaining the number of maintenance times of the heating mechanism.

[0105] S420: If the number of maintenance times is greater than a preset maintenance times threshold, a prompt message is sent to the cooking device and the mobile terminal indicating that the heating mechanism is frequently maintained and that it is recommended to apply for replacement of the device.

[0106] When the number of heating tube maintenance times exceeds the limit, it means that the heating tube is frequently maintained, and a prompt message is issued at this time to suggest applying for replacement.

[0107] In a second aspect, the present application provides a control device for a cooking device, such as Figure 2 As shown, the device includes: a first acquisition module 10, a second acquisition module 20, a judgment module 30, and a prompt module 40.

[0108] The first acquisition module 10 is used to acquire, for each heating mechanism in the cooking device, the current preheating time and the accumulated working time of the heating mechanism in the current operating mode.

[0109] The second acquisition module 20 is used to acquire a specified number of historical preheating durations close to the current time in the database, wherein the historical preheating durations correspond to the current operating mode and the heating mechanism.

[0110] The judgment module 30 is used to judge whether the current preheating time and a specified number of historical preheating time are both greater than the preheating time threshold corresponding to the current operation mode, and / or whether the accumulated working time is greater than the working time threshold.

[0111] The prompt module 40 is used to send a prompt message for repairing or replacing the heating mechanism to the cooking device and a mobile terminal that is communicatively connected to the cooking device after the cooking device reaches the target temperature, if the current preheating time and a specified number of historical preheating times are both greater than a preheating time threshold corresponding to the current operating mode, and / or the cumulative working time is greater than the working time threshold.

[0112] In a third aspect, the present application provides a cooking device, which is communicatively connected to a control mechanism and a mobile terminal, and the control mechanism is used to execute the above method.

[0113] In a fourth aspect, an embodiment of the present application provides an electronic device, Figure 3 As shown, the electronic device includes a memory 131 and a processor 130, the memory 131 is used to store computer programs, and the processor 130 runs the computer programs to enable the electronic device to perform the above-mentioned layered verification method based on traffic recording and playback.

[0114] Furthermore, combined with Figure 3 The electronic device shown further includes a bus 132 and a communication interface 133 , and the processor 130 , the communication interface 133 and the memory 131 are connected via the bus 132 .

[0115] The memory 131 may include a high-speed random access memory (RAM), and may also include a non-volatile memory, such as at least one disk storage. The communication connection between the system network element and at least one other network element is realized through at least one communication interface 133 (which may be wired or wireless), and the Internet, wide area network, local area network, metropolitan area network, etc. may be used. The bus 132 may be an ISA bus, a PCI bus, or an EISA bus, etc. The bus may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, Figure 3 Only one bidirectional arrow is used in the diagram, but this does not mean that there is only one bus or only one type of bus.

[0116] The processor 130 may be an integrated circuit chip with signal processing capabilities.
