[0013] According to this application, when the temperature sensing device of the cooking appliance malfunctions, the cooking appliance can no longer control the heating device to work according to the cooking temperature. At this time, the cooking appliance can seek help from the server and receive power control data from the server.

[0179] Unless otherwise stated, the numerical ranges in this document include not only the entire range within its two endpoints, but also the subranges contained therein.

[0180] This application provides a cooking appliance and a server for the cooking appliance, a cooking system including the cooking appliance and the server, and a cooking control method for the cooking system.

[0181] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

[0182] like Figure 1 As shown, in a specific embodiment, the cooking system 100 according to this application includes a server 50 according to this application and at least one cooking appliance 10 according to this application, wherein the server 50 and the cooking appliance 10 can communicate wirelessly.

[0183] Specifically, server 50 includes a server control device 51 and a server wireless communication device 53. The server control device 51 and the server wireless communication device 53 are electrically connected, so that the server wireless communication device 53 can wirelessly communicate with other devices under the control of the server control device 51. Cooking appliance 10 includes a terminal control device 41 and a terminal wireless communication device 43. The terminal control device 41 and the terminal wireless communication device 43 are electrically connected, so that the terminal wireless communication device 43 can wirelessly communicate with other devices under the control of the terminal control device 41. The server wireless communication device 53 and the terminal wireless communication device 43 communicate wirelessly under the control of their respective control devices, thereby realizing wireless communication between server 50 and cooking appliance 10.

[0184] The terminal control device 41 can be, for example, a microcontroller unit (MCU). The terminal wireless communication device 43 can be a WIFI module, Bluetooth module, IoT module, etc. Depending on the specific product performance, the terminal wireless communication device 43 and the server wireless communication device 53 are connected through necessary gateways, routers, relay equipment, etc. This application does not impose specific restrictions on the configuration of the terminal wireless communication device 43.

[0185] The following section will first introduce the structure of cooking utensil 10.

[0186] like Figure 2 and Figure 3As shown, the cooking utensil 10 may include a pot body 30 and a lid 20. Typically, the pot body 30 includes an inner pot 31, which is a cooking container for holding food. The interior space of the inner pot 31 is a cooking cavity 32. The pot body 30 may have a cylindrical (or other shaped) receiving cavity 34, from which the inner pot 31 can be freely placed or removed for easy cleaning. The inner pot 31 is made of metal and constructed as a rotating body with an opening and an inner cavity formed by the pot wall. The capacity of the inner pot 31 is typically less than 6L; for example, the capacity of the inner pot 31 may be 2L or 4L. The lid 20 is pivotally connected to the pot body 30 via a pivot axis for closing the pot body 30.

[0187] The cooking appliance 10 has a heating element 33 for performing cooking heating. The heating element 33 (e.g., a coil) is typically located at the bottom of the pot body 30, for example, below the inner pot 31. The heating element 33 is electrically connected to a terminal control device 41 for heating the inner pot 31 under the control of the terminal control device 41, thereby realizing the cooking function.

[0188] The cooking appliance 10 also includes a temperature sensing device 42 for sensing the cooking temperature. The temperature sensing device 42 is electrically connected to a terminal control device 41, allowing the terminal control device 41 to obtain cooking temperature information and control the heating device 33 to operate based on this information. The temperature sensing device 42 may include, for example, a top temperature sensor 21 and / or a bottom temperature sensor 35. The top temperature sensor 21, for example, is disposed in the lid 20 and is used to sense the cooking temperature at the top of the cooking cavity 32. The bottom temperature sensor 35, for example, is disposed in the pot body 30 and is used to contact the bottom of the inner pot 31 to sense the cooking temperature at the bottom of the cooking container.

[0189] A steam valve 22 may also be provided in the cover 20 to exhaust steam in the cooking chamber 32 into the environment.

[0190] Understandably, the control method of cooking appliance 10 is executed through terminal control device 41, and the control method of server 50 is executed through server control device 51. The cooking control method of this application is executed collaboratively by terminal control device 41 and server control device 51.

[0191] To address the problems in the background art, the cooking system 100 operates according to the following cooking control method. The server 50 stores at least one set of operating model data, each set of operating model data including at least power model data of the heating power of the cooking appliance changing over time (e.g., power model data of the cooking appliance's heating power changing over time). Figure 4The data line C1 in the cooking appliance 10 is used to determine whether the temperature sensing device 42 is working properly during the cooking process (e.g., cooking rice, cooking porridge, etc.). When the temperature sensing device 42 is determined to be malfunctioning, the cooking appliance 10 sends a device failure signal to the server 50, indicating that the temperature sensing device is malfunctioning. After receiving the device failure signal, the server 50 selects a set of working model data from at least one set and sends at least a portion of the power model data from the selected working model data to the cooking appliance 10 as power control data. The cooking appliance 10 receives the power control data from the server 50 and controls the heating device 33 to work according to the power control data.

[0192] Understandably, in the cooking control method of this application, the wireless communication between the server 50 and the cooking appliance 10 is achieved through wireless communication between the server wireless communication device 53 and the terminal wireless communication device 43. After the terminal wireless communication device 43 receives the power control data from the server wireless communication device 53, the terminal control device 41 controls the heating device 33 to operate according to the power control data.

[0193] like Figure 1 As shown, server 50 includes server storage device 52 for storing at least one set of working model data. Server storage device 52 is electrically connected to server control device 51, so that server control device 51 can access the stored data in server storage device 52. Server storage device 52 can be local storage of server 50, wired and electrically connected to server control device 51; or it can be a cloud database, wirelessly connected to server control device 51 (wireless communication). This application does not specifically limit this.

[0194] The temperature sensing device 42 typically employs a thermistor, which is connected in series with a constant resistor to form a voltage divider circuit. The terminal control device 41 obtains the sensed temperature value by detecting the voltage value of the thermistor. During normal operation, the terminal control device 41 periodically acquires the voltage value of the thermistor at a certain sampling rate, thereby adjusting the power of the heating device 33 in a timely manner. When the voltage value of the thermistor is 0 for an extended period or the power supply voltage is low, it can be determined that the temperature sensing device 42 is malfunctioning. Malfunction of the temperature sensing device 42 includes at least one malfunction of the top temperature sensor 21 and the bottom temperature sensor 35; that is, the failure of any one of the temperature sensors in the cooking appliance 10 constitutes a malfunction of the temperature sensing device 42. When the cooking appliance 10 has both a top temperature sensor 21 and a bottom temperature sensor 35, the device failure signal can indicate that the bottom temperature sensor 35 is malfunctioning but the top temperature sensor 21 is functioning normally, or the bottom temperature sensor 35 is functioning normally but the top temperature sensor 21 is malfunctioning, or both the bottom temperature sensor 35 and the top temperature sensor 21 are malfunctioning.

[0195] According to the cooking control method of this application, the working model data of the server 50 is model data of the complete cooking process of the cooking appliance pre-saved in the experiment, which can be understood as a standard working template. The power model data is a complete template of the heating power changing over time. When the temperature sensing device 42 of the cooking appliance 10 malfunctions (e.g., due to temperature sensor damage, poor contact, circuit failure, etc. causing abnormal operation of the temperature sensing device), the terminal control device 41 can no longer control the heating device 33 to work based on the sensing data of the temperature sensing device 42. Therefore, the cooking appliance 10 seeks help from the server 50. The server 50 sends the heating power template data to the cooking appliance 10, and the heating device 33 continues to work according to the power template data, thereby completing the cooking function.

[0196] Specifically, the cooking system 100 can be pressed Figure 5 The workflow is as follows: After the cooking appliance 10 is powered on, or before performing the cooking function, it sends a handshake signal to the server 50. Upon receiving the handshake signal from the cooking appliance 10, the server 50 also sends a handshake signal to the cooking appliance 10, thereby establishing a connection between the two. After the cooking appliance 10 begins performing the cooking function, during the performance of the cooking function, the terminal control device 41 determines whether the temperature sensing device 42 is working properly, for example, by periodically acquiring the operating parameters of the thermistor. When it is determined that the temperature sensing device 42 is malfunctioning, the terminal control device 41 controls the terminal wireless communication device 43 to send a device failure signal to the server wireless communication device 53. When the server wireless communication device 53 receives the device failure signal representing the malfunction of the temperature sensing device 42 sent by the terminal wireless communication device 43 of the cooking appliance 10, the server control device 51 selects a set from at least one set of operating model data and controls the server wireless communication device 53 to send at least a portion of the power model data from the selected operating model data to the terminal wireless communication device 43 of the cooking appliance 10 as power control data. Then, the terminal wireless communication device 43 receives the power control data from the server wireless communication device 53, and the terminal control device 41 controls the heating device 33 to continue working according to the power control data.

[0197] When server 50 sends data to cooking appliance 10, it can group and send the data in batches according to device performance, network performance, etc., for example, sending 5-10 seconds of power control data each time. Server 50 and cooking appliance 10 can also mutually confirm the data sent and received through a protocol to ensure that the data transmission is error-free and not lost.

[0198] Cooking appliances 10 can have different models, and different models of cooking appliances 10 have different heating performances, for example, the operating curves of heating devices 33 are different. To better control the operation of heating devices 33, preferably, the server 50 is configured to design operating model data based on at least the device model of the cooking appliance 10. For cooking appliances 10 of the same device model, the server storage device 52 stores at least one set of operating model data. In other words, the operating model data of the server 50 has a device model attribute, and the operating model data may differ when the device models are different. The terminal control device 41 also controls the terminal wireless communication device 43 to send the device model information of the cooking appliance 10 to the server 50, for example, during a handshake, when the cooking function is started, when a device malfunction signal is sent, or at other times. Then, the server wireless communication device 53 receives the device model information sent by the cooking appliance 10, and the server control device 51 selects a set of operating model data with the same device model attribute based on this information, and then sends power control data.

[0199] Cooking appliance 10 can perform different cooking functions (e.g., cooking rice and porridge, cooking firmer rice and cooking softer rice). The heating performance of cooking appliance 10 differs under different cooking functions; for example, the operating curve of heating device 33 differs. To better control the operation of heating device 33, preferably, server 50 is configured to design working model data based on at least the cooking functions of cooking appliance 10. For the same cooking function of cooking appliance 10, server storage device 52 stores at least one set of working model data. In other words, the working model data of server 50 possesses cooking function attributes, and the working model data may differ when the cooking function is different. Terminal control device 41 also controls terminal wireless communication device 43 to send information about the cooking function of cooking appliance 10 to server 50, for example, when the cooking function is started, when a device malfunction signal is sent, or at other times. Then, the server wireless communication device 53 receives cooking function information sent by the cooking appliance 10, and the server control device 51 selects a group from the working model data with the same cooking function attributes based on the cooking function information, and then sends power control data.

[0200] Cooking appliance 10 can be located in different regions, and different regions have different altitudes (different boiling points), resulting in different heating performances of cooking appliance 10 in different regions, for example, different operating curves of heating device 33. To better control the operation of heating device 33, preferably, server 50 is configured to design operating model data based on at least the operating region of cooking appliance 10. For the same operating region, server storage device 52 stores at least one set of operating model data. In other words, the operating model data of server 50 has an operating region attribute, and the operating model data may differ when the operating region is different. Figure 1 As shown, the cooking appliance 10 also includes a positioning device 44 (e.g., GPS) for obtaining the location of the cooking appliance 10. The positioning device 44 is electrically connected to the terminal control device 41, so that the terminal control device 41 can obtain the location information of the cooking appliance 10. The terminal control device 41 also controls the terminal wireless communication device 43 to send the location information of the cooking appliance 10 to the server 50, for example, during a handshake, when the cooking function is started, when a device malfunction signal is sent, or at other times. Then, the server wireless communication device 53 receives the location information sent by the cooking appliance 10, and the server control device 51 selects a group from the working model data with the same working area (attribute) based on the location information, and then sends power control data.

[0201] Understandably, the more information the server 50 obtains from the cooking appliance 10, and the more attributes the server 50 has in its working model data, the more beneficial it is for matching the best working model data.

[0202] Preferably, the cooking control method of this application designs working model data based on the equipment model, cooking function, and working area of ​​the cooking appliance 10. For the same equipment model, performing the same cooking function, and being located in the same working area, at least one set of working model data is stored. That is, each set of working model data has equipment model, cooking function, and working area attributes. The cooking appliance 10 sends its equipment model, cooking function, and location to the server 50. The server 50 selects a set from the working model data with the same equipment model, cooking function, and working area (attribute), and then sends power control data.

[0203] In practice, the temperature sensing device 42 may malfunction before the cooking function is executed (i.e., before the heating device 33 has started working), or it may malfunction after the cooking function has been executed for some time (i.e., the heating device 33 has been working for some time, but has not yet completed the entire heating process). Understandably, when the temperature sensing device 42 malfunctions midway through the cooking function, the heating work already performed is effective, and the cooking system 100 needs to solve the problem of how the heating device 33 should work subsequently, that is, it needs to determine which specific data from the complete power model data of the working model data should be sent to the cooking appliance 10.

[0204] To this end, on the one hand, from the moment cooking and heating begins, the terminal control device 41 also periodically controls the terminal wireless communication device 43 to send the temperature sensing data and the heating power data of the heating device 33 to the server 50. The temperature sampling period and the data transmission period of the terminal control device 41 can be the same or different. The server 50 receives the temperature sensing data and heating power data sent by the cooking appliance 10, thereby obtaining information about the existing working status of the cooking appliance 10. Based on the received temperature sensing data and heating power data, and after analyzing the existing working status, the server 50 selects a set of working model data and selects appropriate power model data from the selected working model data to send to the cooking appliance 10.

[0205] For example, each set of working model data stored in the server storage device 52 also includes temperature model data of the cooking appliance 10's heating temperature changing over time, corresponding to the power model data. If the temperature sensing device 42 malfunctions during the cooking function, when the server 50 receives the device malfunction signal, the server 50 has already received the temperature sensing data and heating power data of the cooking appliance 10. In this case, the server control device 51 of the server 50 compares the received heating power data with the power model data in at least one set of working model data, and compares the received temperature sensing data with the temperature model data in the corresponding working model data. Based on the comparison results (e.g., two comparison results), it selects a set of working model data and selects appropriate power model data from the selected working model data to send to the cooking appliance 10.

[0206] Specifically, the server control device 51 of server 50 selects, for example, from at least one set of working model data the working model data whose template temperature model data is closest (similar) to the actual temperature sensing data (e.g., it can calculate the similarity, correlation, etc. of the effective parts of two data curves and select the template with the highest similarity or correlation). The server control device 51 can also determine the first progress point of the cooking process corresponding to the abnormal operation of the temperature sensing device 52 based on the above comparison results (that is, determine at which specific time point of the cooking process the temperature sensing device 52 malfunctions), and send the power model data after the first progress point in the selected working model data to the cooking appliance 10.

[0207] On the other hand, the working model data stored in the server storage device 52 includes general working model data (i.e., general templates), such as general working model data designed according to one or more of the cooking appliance 10's model, cooking function, and working area. When the server wireless communication device 53 receives a device failure signal, if the server wireless communication device 53 does not receive the temperature sensing data and heating power data of the cooking appliance 10, it means that the temperature sensing device 42 has malfunctioned before the cooking function was executed. The server cannot know the existing working status information of the cooking appliance 10, and at this time, the terminal control device 41 has not yet driven the heating device 33 to work. In this case, the server control device 51 selects the general working model data or the general model data with matching attributes, and controls the server wireless communication device 53 to send all the power model data in the selected general working model data to the cooking appliance 10. Thus, all the power control data of the heating device 33 comes from the server 50, and the temperature sensing device 42 does not play any role in the cooking process.

[0208] Optionally, when the terminal control device 41 determines that the temperature sensing device 42 is malfunctioning, it controls the terminal wireless communication device 43 to stop sending temperature sensing data and heating power data to the server 50. Since subsequent temperature sensing data is unreliable and the cooking appliance 10 has already obtained power control data from the server, stopping the cooking appliance 10 from sending data can save resources and simplify control.

[0209] As mentioned earlier, when the temperature sensing device 42 malfunctions midway through the cooking function, the server 50 can obtain information about the operating status of the cooking appliance 10. If the temperature sensing device 42 malfunctions shortly after the cooking function begins, the server 50 receives relatively little temperature sensing data and heating power data, resulting in fewer analytical results and a smaller contribution to matching the optimal operating model data. In other words, the reliability of the data received by the server 50 is relatively low in this case. If the temperature sensing device 42 malfunctions a considerable amount of time after the cooking function begins, the server 50 receives relatively more temperature sensing data and heating power data, resulting in more analytical results and a larger contribution to matching the optimal operating model data. In other words, the reliability of the data received by the server 50 is relatively high in this case. Therefore, the server control device 51 is configured such that if the comparison result meets the preset conditions, indicating that the data sent by the cooking appliance 10 has high reliability, then it selects a set of non-general working model data from at least one set of working model data stored in the server storage device 52, and selects power model data from the selected non-general working model data to send to the cooking appliance 10; if the comparison result does not meet the preset conditions, indicating that the data sent by the cooking appliance 10 has low reliability, then it selects general working model data from at least one set of working model data stored in the server storage device 52, and selects power model data from the selected general working model data to send to the cooking appliance 10.

[0210] Specifically, the aforementioned preset condition is, for example, the ability to analyze the amount of food in the cooking appliance 10. That is, if the amount of food in the cooking appliance 10 can be analyzed based on the comparison results of the temperature sensing data and heating power data sent by the cooking appliance 10 with the working model data, then the preset condition is considered to be met, the server 50 accepts the data sent by the cooking appliance 10, and matches the best working template based on these data; if the amount of food in the cooking appliance 10 cannot be analyzed based on the above comparison results, then the preset condition is considered not to be met, the server 50 does not accept the data sent by the cooking appliance 10, and adopts a general working template.

[0211] For example, the amount of food cooked in the cooking appliance 10 varies each time, resulting in different heating performance of the appliance 10, such as different operating curves for the heating device 33. The server 50 can design working model data based at least on the amount of food, and the working model data will differ depending on the amount of food. In other words, the working model data of the server 50 has an attribute related to the amount of food. When the above comparison results meet the preset conditions, that is, when the amount of food in the cooking appliance 10 can be analyzed, the server control device 51 selects the set of working model data from the server storage device 52 whose amount of food (attribute) is closest to the analyzed amount of food in the cooking appliance 10, and then selects power model data from that set of working model data and sends it to the cooking appliance 10.

[0212] When the preset condition is that the amount of ingredients in the cooking appliance 10 can be analyzed, the process of analyzing the amount of ingredients is also the process of matching the data sent by the cooking appliance 10 with the template data. When a suitable template data is matched, the amount of ingredients is also analyzed at the same time. If there is no matching template, the amount of ingredients cannot be analyzed. In other words, the selected matching template is the template that satisfies the preset condition.

[0213] When the cooking appliance 10 has both a top temperature sensor 21 and a bottom temperature sensor 35, the temperature sensing data sent by the cooking appliance 10 includes top temperature sensing data sensed by the top temperature sensor 21 and bottom temperature sensing data sensed by the bottom temperature sensor 35. Correspondingly, the temperature model data for each set of working model data in the server 50 includes bottom temperature model data (e.g., the temperature of the bottom of the cooking container (inner pot 31) of the cooking appliance 10 as the cooking temperature changes over time). Figure 4 The data line C3 in the middle, and the top temperature model data of the cooking heating temperature over time corresponding to the top of the cooking cavity 32 of the cooking appliance 10 (such as the top temperature model data of the top temperature over time). Figure 4 (Data cable C2 in the middle).

[0214] At this point, comparing the temperature sensing data of the cooking appliance 10 with the temperature model data of the server 50 requires comparing the top temperature sensing data of the cooking appliance 10 with the top temperature model data of the server 50, and comparing the bottom temperature sensing data of the cooking appliance 10 with the bottom temperature model data of the server 50. The comparison of the top temperature may include, for example, at least one of the following: initial temperature, temperature rise slope, and time taken to reach the preset temperature. The comparison of the bottom temperature may include, for example, at least one of the following: initial temperature, temperature rise slope, temperature fall slope, and time taken to reach the preset temperature. The server control device 51 is configured to select one set of operating model data from at least one set based on the comparison results of the top and bottom temperatures, and the power comparison results, and control the server wireless communication device 53 to send at least a portion of the power model data from the selected operating model data to the cooking appliance 10.

[0215] When the top temperature sensor 21 and the bottom temperature sensor 35 malfunction before the cooking function begins, the server 50 sends all power model data from the universal operating model data. When the top temperature sensor 21 and the bottom temperature sensor 35 malfunction after the cooking function has started, if the data sent by the cooking appliance 10 does not meet the preset conditions, the universal operating model data is selected; if the data sent by the cooking appliance 10 meets the preset conditions, the matching non-universal operating model data is selected.

[0216] When one of the top temperature sensor 21 and the bottom temperature sensor 35 fails (that is, the device failure signal indicates that one of the top temperature sensor 21 and the bottom temperature sensor 35 is working normally and the other is malfunctioning), the server control device 51 adopts different control methods according to the sensing signal of the malfunctioning temperature sensor received by the server wireless communication device 53.

[0217] For example, if the server's wireless communication device fails to receive sensing data from an abnormal temperature sensor (the temperature sensor malfunctioned before cooking began), or if the comparison result based on the received sensing data from an abnormal temperature sensor does not meet the preset conditions (the temperature sensor malfunctioned shortly after cooking began), in both cases, the malfunctioning temperature sensor fails to provide sufficient reliable information. The cooking control method of this application includes: firstly, selecting a set of general working model data from at least one set of working model data from server 50, and sending the power model data after the first progress point in the selected general working model data to cooking appliance 10; simultaneously, server 50 continues to receive heating power data from cooking appliance 10 and sensing data from a normal temperature sensor, and compares the received heating power data with the power model data in at least one set of non-general working model data, and compares the sensing data of a normal temperature sensor with the corresponding temperature model data in the corresponding non-general working model data; when the comparison result meets a preset condition (indicating that a working template has been matched), server control device 51 determines the second progress point of the cooking process corresponding to the satisfaction of the preset condition, and sends the power model data after the second progress point in the matched non-general working model data to cooking appliance 10. It is understood that in this case, the data from a malfunctioning temperature sensor cannot help match the working template, but can help determine the time point of its malfunction.

[0218] If the sensing signal from the malfunctioning temperature sensor is sufficiently reliable and meets the preset conditions, a suitable common working template can be matched. Then, the cooking appliance 50 sends the power model data after the first progress point in the matched non-common working model data to the cooking appliance 10.

[0219] Typically, the cooking process of the cooking appliance 10 includes a rapid heating step, in which high heat is used to heat the ingredients from a lower temperature to near boiling point. This step takes less time when the amount of ingredients is small, and longer when the amount is large. Therefore, the duration of the rapid heating step can be determined by the actual heating power of the cooking appliance 10, and the amount of ingredients can be determined based on the rate of temperature change during that period.

[0220] Alternatively, the aforementioned preset conditions could be requirements for data length, temperature difference in temperature sensing data, etc. Server 50 can determine the reliability of the data sent by cooking appliance 10 according to different rules.

[0221] The cooking system 100 may include multiple cooking appliances 10, and the server 50 can establish connections with these appliances 10 to maximize the effectiveness of its standard operating template. The cooking appliances 10 in the cooking system 100 may have different models, be located in different regions, and perform different cooking functions. As described above, the more detailed the attributes of the operating model data in the server 50, the more accurately the server 50 can provide control data for the cooking appliances 10. The operating model data in the server 50 can be obtained by collecting a large amount of operating data from cooking appliances 10 of different models, in different regions, performing different cooking functions, and cooking different amounts of ingredients, and then classifying and organizing this data.

[0222] Each cooking appliance 10 in the cooking system 100 is connected to the server 50 during operation; that is, the server control device 51 also controls the server wireless communication device 53 to achieve wireless communication with multiple cooking appliances 10. When the cooking appliance 10 does not experience a malfunction in its temperature sensing device 42, its shared data is of great reference value. Preferably, the server control device 51 updates at least one set of working model data stored in the server storage device 52 based on the temperature sensing data and heating power data of at least one cooking appliance 10 that did not send a device malfunction signal. For example, the server control device 51 finds at least one set of working model data with matching attributes based on at least one of the cooking function, appliance model, and working area sent by the cooking appliance 10, and updates the working model data based on the received actual working data. For example, the server control device 51 first normalizes the valuable actual working data based on the existing working model data (e.g., normalizes the data length), and then updates the working model data based on the normalized actual data. For example, weights can be assigned to the new actual data and the existing working model data respectively, and the two sets of data can be summed according to the weights.

[0223] As the cooking appliance 10 ages, its various components will change to varying degrees, altering its optimal operating curve. The server 50 modifies the template data based on this constantly changing operating curve, making the template data more suitable for the appliance. Because the server 50 can continuously update the operating template, when power model data is sent to the cooking appliance 10 where the temperature sensing device 42 malfunctions, in the case of batch data transmission, the next batch of data may have already been updated in real time.

[0224] In this application, server 50 can store multiple sets of general working model data, that is, multiple sets of general working templates. For example, general working model data can be designed based on at least one of the following: the equipment model of cooking appliance 10, cooking function, working area, and ingredient quantity. In other words, general working model data can also have at least one of the following attributes: equipment model, cooking function, working area, and ingredient quantity. General working model data is also one type of working model data stored in server storage device 52.

[0225] Compared to the technical solution of storing the working template data in the cooking appliance 10's own memory, the technical solution of this application can save storage resources for the cooking appliance 10. Furthermore, multiple identical (model) cooking appliances 10 can share the same template in the same server 50, meaning only one copy of the template data needs to be stored, thus saving overall storage resources. Moreover, the same server 50 can serve different (models) of cooking appliances 10, further saving overall storage resources. When updating the working template data, only the data in the server 50 needs to be updated, instead of updating the data in each individual cooking appliance 10, making the operation simpler and the work more efficient.
