Description

Technical Field

[0001] The present application relates to the technical field of cooking equipment, and more specifically, to a cooking control method, device, cooking utensil, and storage medium. Background Art

[0002] Currently, cooking equipment such as induction cookers mainly rely on temperature sensors to determine whether the contents of the cooking container are boiling. However, since the temperature sensor and the contents of the cooking container are separated by a support platform and other structures such as the cooking container, the detection results of the temperature sensor are inaccurate and have a lag. When the contents of the cooking container are boiling, the cooking equipment cannot detect it in time and make a reasonable response, which will reduce the user experience. Summary of the Invention

[0003] The present application proposes a cooking control method, a cooking device, a cooking utensil, and a computer-readable storage medium to improve the above-mentioned technical problems.

[0004] In a first aspect, an embodiment of the present application provides a cooking control method, which is applied to a cooking utensil, wherein the cooking utensil includes a carrying platform for carrying a cooking container and a weight detection device arranged on the carrying platform, and the weight detection device is used to detect the weight of the cooking container and its contents; the cooking control method includes: during the cooking process, obtaining the weight change of the cooking container and its contents; and determining the boiling state of the contents of the cooking container based on the weight change.

[0005] In a second aspect, embodiments of the present application further provide a cooking control device. The cooking control device is applied to a cooking appliance, the cooking appliance comprising a platform for supporting a cooking container and a weight detection device disposed on the platform, the weight detection device being configured to detect the weight of the cooking container and its contents. The cooking control device comprises: a weight acquisition module for acquiring weight changes of the cooking container and its contents during the cooking process; and a boiling state confirmation module for determining the boiling state of the contents of the cooking container based on the weight changes.

[0006] In a third aspect, an embodiment of the present application further provides a cooking appliance, comprising a carrying platform for carrying a cooking container and a weight detection device arranged on the carrying platform, the weight detection device being used to detect the weight of the cooking container and its contents; the cooking appliance further comprises: one or more processors, a memory, and one or more applications; wherein the one or more applications are stored in the memory and configured to be executed by one or more processors, and the one or more applications are configured to execute the cooking control method as described above in the claims.

[0007] In a fourth aspect, an embodiment of the present application further provides a computer-readable storage medium, in which a program code is stored, and the program code is called by a processor to execute the above-mentioned cooking control method.

[0008] Compared to the prior art, the cooking control method provided in the embodiments of the present application does not require detecting the temperature of the cooking container's contents to determine whether the contents are boiling. Instead, it determines whether the contents are boiling by detecting the weight of the cooking container and its contents on the support platform. Specifically, at the beginning of cooking, the contents of the cooking container are not boiling, and the weight of the cooking container and its contents barely changes. As the contents boil, the weight of the contents decreases due to evaporation, resulting in a continuous decrease in the weight of the cooking container and its contents. Therefore, during the cooking process, eliminating human interference, the weight of the cooking container and its contents can more accurately represent the boiling state of the contents. The cooking control method provided in the embodiments of the present application can determine the boiling state relatively accurately and promptly. For example, when the weight of the cooking container and its contents decreases, it can be determined that the contents are boiling. Subsequently, an alarm can be issued to alert the user to promptly detect the boiling state, or after the boiling state is determined, the heating power can be automatically adjusted to a low level to meet the requirements of a low-heat simmer, thereby preventing overboiling, improving safety during the cooking process, and enhancing the user experience.

[0028] The following introduces the application environment of the cooking control method provided by the present invention.

[0029] Please refer to Figure 1 , Figure 1 Schematic diagram of an application scenario of a cooking control method provided by an embodiment of the present invention. Figure 1As shown, it shows a schematic diagram of a cooking utensil 100 provided in one embodiment of the present application. The cooking utensil 100 provided in the embodiment of the present application can have any suitable type of cooking function. For example, it can be an induction cooker with a heating function, an automatic cooking machine with a stir-fry function, an electric hot pot with a heating function, or a combined cooking utensil 100 with a combination of the above functions. In the embodiment of the present application, the cooking utensil 100 can be specifically an induction cooker with a heating function. In other embodiments, the cooking utensil 100 can be an electric rice cooker, a health pot, a stew pot, a steam rice cooker, a cooking machine, etc., without limitation. This application takes the cooking device as an induction cooker as an example for specific introduction.

[0030] The cooking appliance 100 includes a housing 11, a carrier 13, and a cooking mechanism 12. The carrier 13 is disposed on the housing 11 and can be used to place a cooking container (such as a pot, a basin, etc.), which is used to hold food to be cooked (i.e., ingredients). The cooking mechanism 12 is used to heat and cook the food in the cooking container. As an example, the carrier 13 can be a stovetop on an induction cooker, and the cooking mechanism 12 can be a heating module inside the induction cooker. During use, the user places the cooking container on the carrier 13, and the cooking mechanism 12 can heat the contents of the cooking container through the carrier 13 to achieve the cooking purpose.

[0031] The cooking mechanism 12 may include a heating device, which is used to heat the carrier 13. Specifically, in this embodiment, the heating device is arranged inside the outer shell 11, and can be specifically arranged below the carrier 13. When the heating device is working, heat can be transmitted to the outside through the carrier 13. The heating device can be a light wave tube. It should be noted that in some other embodiments, the heating device is not limited to other single or superimposed multiple heating device methods, and can be in the form of the following and several heating devices, such as heating coils, heating belts, etc., which are not limited in this embodiment. In some embodiments, a reflective cover and a heat insulation board (not shown in the figure) can be provided above the heating device to isolate the heating device, conduct heat, and improve heat utilization.

[0032] In some embodiments, the cooking appliance 100 may also include a weight detection device 14. This device is used to detect changes in the weight of the cooking container and its contents on the support platform 13 during cooking, thereby confirming the boiling state of the cooking container's contents. In this embodiment, the bottom of the housing 11 of the cooking appliance 100 is provided with legs, and the weight detection device 14 is located at the bottom of the legs. At the start of cooking, the weight detected by the weight detection device 14 is the sum of the weight of the cooking appliance 100, the weight of the cooking container, and the weight of the cooking container's contents. Since the weights of the cooking appliance 100 and the cooking container are fixed values, changes in the weight detection device 14 indicate a change in the weight of the cooking container's contents. For example, a decrease in the weight detection device 14 indicates a decrease in the weight of the cooking container's contents. Excluding human intervention, this indicates that the contents of the cooking container are boiling, and that the contents are losing weight due to evaporation of water after boiling. As a specific example, the weight detection device 14 may be a load cell or a pressure sensor. In some other embodiments, the housing 11 is provided with a control panel 15 for displaying information and allowing the user to operate the cooking appliance 100. For example, the user can adjust the operating mode of the cooking appliance 100 through the control panel 15. The weight detection device 14 is electrically connected to the control panel 15 and is capable of displaying its own detection value on the control panel 15 in real time, so that the user can promptly obtain information about the boiling state of the contents of the cooking container. In the embodiments of the present application, the boiling state refers to the state when the contents of the cooking container (such as water, soup, etc.) have basically reached the boiling point. When the contents boil, a large number of bubbles emerge inside the contents. At this time, the heat provided by the external environment is used to convert the contents from liquid to gas, and the temperature of the contents remains unchanged. Specifically, boiling refers to the phenomenon of violent vaporization occurring simultaneously inside and on the surface of a liquid when it is heated above its saturation temperature. Different liquids have different boiling points. For the same liquid, its boiling point also changes with changes in external atmospheric pressure.

[0033] In some embodiments, the cooking appliance 100 may further include a fan assembly 16. The housing 11 is provided with an exhaust vent 111. The fan assembly 16 is positioned within the housing 11, with its outlet facing the exhaust vent 111. During cooking, the fan assembly 16 is used to discharge high-temperature air from the housing 11 through the exhaust vent 111 to prevent the air temperature from being too high and potentially causing damage to other electrical components within the housing 11. In some embodiments, the fan assembly 16 has different operating gears, such as high, medium, and low. When the fan assembly 16 operates in different gears, the fan blades of the fan assembly 16 rotate at different speeds. It is understood that the higher the gear of the fan assembly 16, the faster the fan blades rotate. In this embodiment, there is only one fan assembly 16. In other embodiments, the cooking appliance 100 may be provided with at least one fan assembly 16, or may be provided with no fan assembly 16, which is not limited in this embodiment.

[0034] In some embodiments, the cooking appliance 100 may further include a timing device (not shown) for recording the operating time of the cooking appliance 100, such as heating time. In some embodiments, the timing device may be electrically connected to the control panel 15 on the housing 11 to display the timing result on the control panel 15 in real time, making it convenient for the user to obtain time information.

[0035] In some embodiments, the cooking appliance 100 may further include an electronic control device (not shown in the figure), which is electrically connected to the heating device, the fan assembly 16, the timing device, and the weight collection device, and is used to control the operation of the heating device, the fan assembly 16, the timing device, and the weight collection device. Specifically, the electronic control device is used to control the start or stop of the heating device, the fan assembly 16, the timing device, and the weight collection device, as well as the operating parameters during startup. In some embodiments, the electronic control device may also be connected to the control panel 15 on the housing 11. When the control panel 15 receives an operation signal for any functional control, it generates a corresponding electrical signal and sends it to the electronic control device. The electronic control device controls the cooking appliance 100 based on the electrical signal. In the embodiment of the present application, the electronic control device starts executing the current cooking process after receiving the cooking instruction. Optionally, the electronic control device is a microcontroller unit (MCU), a microprocessor unit (MPU), a central processing unit (CPU), etc.

[0036] In some embodiments, the cooking appliance 100 can also be connected to a mobile device to receive control data sent by the mobile device. The user can operate the mobile device to implement corresponding operations of the cooking appliance 100. For example, the user can input the desired target function (such as the corresponding cooking mode) or the predetermined cooking time for the cooking appliance 100 through the mobile device. The mobile device can encapsulate the corresponding operation data into control data and transmit it to the processing structure. The processing structure then controls the operation of the cooking appliance 100 based on the control data, thereby realizing the mobile device's control over the cooking appliance 100.

[0037] In the embodiments of the present application, Figure 1 The cooking control method provided by the embodiment of the present application is described by taking the cooking appliance 100 as an example. It is understood that the present application is not limited to this, except Figure 1 The cooking utensil 100 shown may also be a cooking utensil with other structural forms, and this application does not limit this.

[0038] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0039] Please refer to Figure 2 , which shows a flow chart of a cooking control method provided by one embodiment of the present application. The cooking control method is applicable to the cooking appliance provided by any of the above embodiments. The method includes the following steps S210 to S220.

[0040] Step S210: During the cooking process, obtain the weight change of the cooking container and its contents.

[0041] The term "cooking process" refers to an intermediate process that begins when a user triggers a cooking instruction and ends when the user closes the cooking instruction. For example, when a user uses a cooking appliance to cook, they can select a start control through a control panel or a mobile device connected to the cooking appliance to instruct the cooking appliance to begin the cooking process. After receiving an operation signal for the start control, the cooking appliance, in response to the operation signal, controls the cooking mechanism to operate at a certain output power to initiate cooking. Simultaneously, the cooking appliance also controls the weight detection device to detect the weight of the cooking container and its contents.

[0042] It should be noted that the cooking mechanism may include a heating device and a fan assembly. During the cooking process, the heating device is controlled to heat the support platform at a certain output power, and the fan assembly is controlled to operate at a certain output power. When the heating device and fan assembly are turned on for heating, either all of them can be turned on, or only some of them can be turned on, which is not limited in this embodiment. The output power of the heating device and fan assembly can be reasonably adjusted according to actual needs. In some embodiments, when a fan assembly is not provided, after receiving an operation signal for the activation control, the cooking appliance controls the heating device to heat the support platform in response to the operation signal. If the activation control is a virtual control, the operation signal can be a single-click operation signal, a double-click operation signal, a sliding operation signal, etc.; if the activation control is a physical control, the operation signal can be a single or multiple press operation signal.

[0043] In some embodiments, obtaining the weight change of the cooking container and its contents refers to determining the increase or decrease in the weight of the cooking container and its contents per unit time, that is, comparing the difference between the weight of the cooking container and its contents at the end time and the initial time of the unit time. If the above difference is a positive number, it means that the weight of the cooking container and its contents increases per unit time; if the above difference is a negative number, it means that the weight of the cooking container and its contents decreases per unit time; if the above difference is zero, it means that the weight of the cooking container and its contents remains unchanged per unit time. The unit time can be any length, such as 1s, 2s, 3s, etc. For example, assuming the unit time is 3s, the starting time of the unit time is T1, and the ending time of the unit time is T1+3. The weight of the cooking container and its contents at time T1 is G1, and the weight of the cooking container and its contents at the ending time T1+3 is G2. By calculating the difference ΔG between G2 and G1 (ΔG=G2-G1), the weight change of the cooking container and its contents can be obtained: if ΔG>0, the weight of the cooking container and its contents increases within the unit time; if ΔG<0, the weight of the cooking container and its contents decreases within the unit time; if ΔG=0, the weight of the cooking container and its contents remains unchanged within the unit time. It should be noted that the unit time should not be too long, otherwise the boiling status of the contents of the cooking container cannot be detected in a timely manner.

[0044] Step S220: Determine the boiling state of the contents of the cooking container according to the weight change.

[0045] In this embodiment, the weight change of the cooking container and its contents may include, but is not limited to, the following: the weight of the cooking container and its contents remains unchanged, and the weight of the cooking container and its contents decreases. In this embodiment, the boiling state refers to the state when the contents of the cooking container (such as liquids such as water and soup) have essentially reached their boiling point. When the contents boil, a large number of bubbles emerge from the contents. At this time, all external heat is used to convert the contents from liquid to gas, and the temperature of the contents remains unchanged. The boiling states of the contents of the cooking container include boiling and non-boiling. The boiling state can be further divided into high boiling, low boiling, and slight boiling based on its intensity (which can be measured by the amount of evaporation). Since the contents of the cooking container do not boil, their weight does not undergo a significant, detectable change. When the contents of the cooking container boil, their water evaporates and their weight decreases. Therefore, in this embodiment, the boiling state of the contents is determined based on the weight change of the cooking container and its contents. Specifically, when the weight of the cooking container and its contents remains unchanged, the cooking appliance can determine that the boiling state of the contents of the cooking container is not boiling; when the weight of the cooking container and its contents decreases, the cooking appliance can determine that the boiling state of the contents of the cooking container is boiling. It should be understood that in the embodiment of the present application, when the "weight change" is used to judge the boiling state, the "weight change" can be understood as the absolute value of the weight increase or decrease per unit time, or it can be understood as the continuous change of weight per unit time. The continuous change can be represented by the "weight change rate". The "weight change rate" refers to the rate of change of weight over time (that is, the value of the weight increase or decrease per unit time / unit time). If a weight curve is drawn with time as the variable, the "weight change rate" at a certain moment can be expressed as the slope of the weight curve at that moment.

[0046] In some embodiments, after the cooking appliance determines that the contents of the cooking container are boiling, it can issue a corresponding boiling prompt, such as a light prompt, voice prompt, buzzer prompt, etc., so that the user can promptly inform the cooking status. In other embodiments, after the cooking appliance determines that the contents of the cooking container are boiling, it can control the cooking mechanism to reduce the heating power, such as maintaining it at a certain heating power, to meet the requirements of the corresponding cooking mode. For example, in a slow simmer mode after boiling, the cooking appliance can control the cooking mechanism to maintain the minimum power when the contents are boiling to ensure that the contents continue to boil slightly.

[0047] In summary, in the cooking control method for a cooking utensil provided in this embodiment, the boiling state of the contents of the cooking container is determined by obtaining the weight change of the cooking container and its contents. Compared to the prior art, the cooking control method provided in the embodiment of the present application does not need to detect the temperature of the contents of the cooking container to determine whether the contents are boiling. Instead, it determines whether the contents are boiling by detecting the weight of the cooking container and its contents located on the supporting platform. Specifically, at the beginning of cooking, the contents of the cooking container are in a non-boiling state, at which time the weight of the cooking container and its contents hardly changes. When the contents boil, the weight of the contents decreases due to evaporation of water, resulting in a continuous decrease in the weight of the cooking container and its contents. Therefore, during the cooking process, excluding human interference factors, the weight of the cooking container and its contents can more accurately represent the boiling state of the contents. The judgment of the boiling state in the cooking control method provided in the embodiment of the present application will be relatively more accurate and timely. For example, when it is detected that the weight of the cooking container and its contents is reduced, it can be determined that the contents of the cooking container are in a boiling state. An alarm can then be issued to remind the user to discover it in time, or after boiling is determined, low-power heating can be automatically adjusted to meet the needs of low-fire stewing, so as to avoid excessive boiling, improve safety during the cooking process, and improve the user experience. Furthermore, it also has the beneficial effects of accurate detection results and rapid temperature control response.

[0048] See also Figure 3 , Figure 3 A flowchart of another cooking control method provided by an embodiment of the present application is shown, which is applicable to the cooking appliance provided by any of the above embodiments. The method includes the following steps S310 to S330.

[0049] Step S310: During the cooking process, obtain the weight change of the cooking container and its contents.

[0050] In some embodiments, the specific implementation of step S310 can refer to step S210 in the above embodiment. To save space, this specification does not elaborate on it.

[0051] In this embodiment, step S310 may specifically include: during the cooking process, obtaining multiple weight data of the cooking container and its contents based on a preset cycle; based on the multiple weight data, determining the weight change rate of the cooking container and its contents, the weight change rate representing the change in the weight of the cooking container and its contents over time.

[0052] The preset period can be understood as the "unit time" mentioned above, and can be any duration, such as 1 second, 2 seconds, 3 seconds, etc., but its value should not be too large. In this embodiment, the preset period is 4 seconds. Acquiring multiple weight data of the cooking container and its contents based on the preset period can be understood as detecting and recording the weight data of the cooking container and its contents at each preset period, starting from the beginning of the first preset period and ending at the end of the last preset period. For example, assuming that the cooking process involves ten preset cycles, then from the start of the first preset cycle to the end of the tenth preset cycle, a total of ten weight data items, G21, G22, G23, G24, G25, G26, G27, G28, G29, G30, and G31, need to be recorded. G21 represents the weight of the cooking container and its contents at the start of the first preset cycle, G22 represents the weight of the cooking container and its contents at the end of the first preset cycle (also the start of the second preset cycle), G23 represents the weight of the cooking container and its contents at the end of the second preset cycle (also the start of the third preset cycle), and so on. Furthermore, after obtaining multiple weight data items, the cooking appliance can plot a curve showing the weight data changing over time to facilitate subsequent determination of the weight change rate.

[0053] In this embodiment, the weight change rate of the cooking container and its contents can be understood as the ratio of the numerical value of the weight change of the cooking container and its contents within a preset period to the preset period (duration). This represents the speed of weight change of the cooking container and its contents within the preset period. A larger weight change rate indicates a faster weight change over time for the cooking container and its contents, i.e., a faster rate of water evaporation from the cooking container's contents. If a weight data curve is plotted over time with time as the variable, the "weight change rate" at a given moment can be represented by the slope of the curve at that moment. It should be understood that the curve can be a fitted curve based on discrete weight data points. Therefore, in this embodiment, to obtain the weight change rate of the cooking appliance at a specific moment or in real time, one only needs to calculate the slope of the weight change curve corresponding to that moment or in real time.

[0054] Step S320: Determine the boiling state of the contents of the cooking container according to the weight change.

[0055] In some embodiments, the specific implementation of step S320 can refer to step S220 in the above embodiment. To save space, this specification does not elaborate on it.

[0056] Furthermore, in this embodiment, the cooking appliance is configured to determine the boiling state of the contents of the cooking container based on the weight change rate. When the weight change rate meets a preset threshold range, the contents of the cooking container are determined to be in a boiling state. The boiling state of the contents of the cooking container includes boiling and non-boiling. The preset threshold range represents the range of weight change rates within a preset time period when water boils. Therefore, when the weight change rate meets the preset threshold range, it indicates that the evaporation rate of the water in the cooking container has reached the evaporation rate corresponding to boiling water, and the contents of the cooking container can be determined to be in a boiling state. If the weight change rate does not meet the preset threshold range, it indicates that the evaporation rate of the water in the cooking container is less than the evaporation rate corresponding to boiling water, and the contents of the cooking container can be determined to be in a non-boiling state.

[0057] like Figure 4 As shown in FIG, as an example, a weight curve L1 is obtained by plotting the weight data over time with time as a variable. Then the “weight change rate” at a certain moment can be expressed as the slope of the weight curve L1 at that moment. Figure 4In the figure, the temperature data of the contents of the cooking container are plotted over time using time as a variable to obtain a temperature curve L2. During the heating phase, from t0 to t1, the temperature of the contents is in a climbing phase due to continuous heating, i.e., the temperature curve L2 continues to increase, and almost no water evaporates from the contents of the cooking container. Therefore, during this time period, the weight curve L1 remains essentially unchanged, and the weight change rate during this phase remains unchanged (the slope of the curve is 0). Around time t1, the weight curve L1 shows a continuous and significant decrease, indicating that the water in the contents of the cooking container is continuously evaporating. This indicates that the contents of the cooking container have boiled, and the heat provided by the outside world is used to transform the contents from liquid to gas. The temperature of the contents remains unchanged after reaching the boiling point, i.e., the temperature curve L2 remains constant. Therefore, at time t1, the slope of the weight curve L1 represents the weight change rate of the cooking container and its contents. In this embodiment, the above-mentioned "preset threshold range" can be represented by a critical threshold, for example, the critical threshold is -0.2 (the starting point of the vertical axis of the weight curve L1 in the figure is a non-zero value), and the specific value of the preset threshold range can be a range less than or equal to -0.2. Of course, in other embodiments, the critical threshold can be other suitable values, for example, -0.05, -0.1, -0.3, -0.4, -0.5, -0.6 and other values ​​can be used as critical thresholds to judge the boiling state under different heating powers. The greater the power, the more intense the boiling, and thus the smaller the critical threshold can be. Therefore, when judging whether the weight change rate meets the preset threshold range, the weight change rate is compared with the critical threshold. If the weight change rate is greater than the critical threshold, it means that the weight change rate does not meet the preset threshold range; if the weight change rate is less than or equal to the critical threshold, it means that the weight change rate has met the preset threshold range. Figure 4 In the weight curve L1, the slope (negative value) of the weight curve L1 during the time period t2-t3 is significantly greater than the slope of the weight curve L1 during the time period t1-t2. It can be considered that the cooking appliance has been power-adjusted at this time, so that after the heating power is reduced, the evaporation rate of the water in the cooking container becomes slower, but the boiling state is still maintained. Figure 4 As shown, the boiling state of the contents of a cooking container can be specifically divided into three states, from strong to weak, namely, a full boil, a low boil, and a slight boil. These three boiling states can be divided according to the weight change rate of the contents of the cooking container. When the weight change rate is less than or equal to a critical threshold and greater than a first critical threshold, the contents of the cooking container are in a slight boil; when the weight change rate is less than or equal to the first critical threshold and greater than a second critical threshold, the contents of the cooking container are in a slight boil; and when the weight change rate is less than or equal to the second critical threshold, the contents of the cooking container are in a full boil. The critical threshold is greater than the first critical threshold, and the first critical threshold is greater than the second critical threshold.

[0058] Step S330: adjusting the heating power of the cooking mechanism according to the boiling state.

[0059] In this embodiment, adjusting the heating power of the cooking mechanism includes at least one of the following operations: increasing the heating power of the cooking mechanism, decreasing the heating power of the cooking mechanism, maintaining the current heating power of the cooking mechanism, or operating the cooking mechanism at a specified heating power (e.g., at a minimum limit power or a certain power value). As an example, if it is determined that the contents of the cooking container are not boiling, the heating power of the cooking mechanism is increased to bring the contents of the cooking container to a boil more quickly. As another example, if it is determined that the contents of the cooking container are boiling, the heating power of the cooking mechanism is decreased to prevent the contents of the cooking container from over-boiling and causing a safety accident (e.g., the soup in the cooking container drying up or the soup in the cooking container splashing out and injuring someone).

[0060] Therefore, in some embodiments, the specific implementation of step S330 may include: when the contents of the cooking container are in a non-boiling state, keeping the cooking mechanism running at the maximum limit power. Figure 5 The figure shows a power curve L3 generated by controlling the cooking mechanism based on the weight change rate in some examples. During the period t0-t1, the contents of the cooking container undergo little evaporation. Therefore, during this period, the weight curve L1 remains essentially unchanged, and the weight change rate remains unchanged during this period (the slope of the curve is 0). At this time, the cooking mechanism operates at its maximum power limit W1 to improve heating efficiency. During the period t1-t2, the slope (negative value) of the weight curve L1 decreases significantly, indicating that the cooking container has reached a boiling state. To ensure a stable boiling state, the heating power of the cooking mechanism is maintained at a moderate power W2 (W2 is less than W1). As can be seen from the figure, when the contents of the cooking container are boiling, the lower the heating power of the cooking mechanism, the flatter the weight curve L1 and the greater the slope (negative value) of the weight curve L1 (the closer to 0). Therefore, in embodiments of the present application, the slope of the weight curve L1 can be controlled to maintain a substantially constant value based on the desired boiling level, thereby meeting different cooking power requirements. This will be explained in detail below.

[0061] In other embodiments, the specific implementation of step S330 may include: when the contents of the cooking container are in a boiling state, controlling the heating power of the cooking mechanism according to the real-time weight change rate of the cooking container and its contents to control the contents of the cooking container to be in a continuous boiling state.

[0062] Specifically, the continuous boiling state represents the dynamic equilibrium state in which the cooking cavity structure cooks food quickly at high temperature without overflowing. When it is determined that the contents of the cooking container are in a boiling state, in order to avoid safety accidents caused by excessive boiling of the contents (such as the soup in the cooking container drying up, or the soup in the cooking container splashing out and injuring people, etc.), it is necessary to reduce the heating power of the cooking mechanism so that the contents of the cooking container can continue to boil and not over-boil. The criterion for judging whether the contents are over-boiling is the weight change rate, which indicates the water evaporation rate of the contents of the cooking container within a preset period. If the weight change rate is too large, it means that the water evaporation rate of the contents of the cooking container within the preset period is too fast, that is, the boiling state is excessive. If the weight change rate is within an appropriate range, it means that the water evaporation rate of the contents of the cooking container within the preset period is within an appropriate range, that is, the boiling state remains stable and does not exceed the limit. Therefore, please refer to Figure 6 In step S330 of this embodiment, as an example, the cooking appliance may further perform the following steps S3301 to S3309:

[0063] Step S3301: while the contents of the cooking container are in a boiling state, obtaining a real-time weight change rate of the cooking container and its contents;

[0064] Step S3303, determining whether the real-time weight change rate meets a preset change range;

[0065] Step S3305: If the real-time weight change rate meets the preset change range, the current heating power is maintained unchanged;

[0066] Step S3307: If the real-time weight change rate is less than the lower limit of the preset change range, determining a first target power and controlling the cooking mechanism to operate at the first target power, wherein the first target power is less than the current heating power;

[0067] Step S3309: If the real-time weight change rate is greater than the upper limit of the preset change range, determine the second target power and control the cooking mechanism to operate at the second target power, wherein the second target power is greater than the current heating power.

[0068] In this embodiment, since the weight of the contents of the cooking container will continue to decrease during the boiling process without human interference, the weight change rate is a negative value. The preset change range can be defined as an interval with two critical values. For example, the preset change range can be a closed interval [-0.5, -0.3]. Then: when the real-time weight change rate is greater than or equal to -0.5 and less than or equal to -0.3, it means that the real-time weight change rate meets the preset change range and the boiling situation meets the requirements, and the cooking appliance can maintain the current heating power of the cooking mechanism unchanged; when the real-time weight change rate is less than -0.5, it means that the real-time weight change rate meets the preset change range and the boiling situation meets the requirements. If boiling is too intense and does not meet the requirements of the dish, the heating power of the cooking mechanism should be reduced. Therefore, the cooking appliance can define the aforementioned first target power to reduce the heating power of the cooking mechanism and thereby reduce the intensity of boiling, for example, to meet the requirements of a slow-cooking cooking mode. If the real-time weight change rate is greater than -0.3, it indicates that boiling is too weak and does not meet the requirements of the dish. Therefore, the heating power of the cooking mechanism should be increased. Therefore, the cooking appliance can define the aforementioned second target power to increase the heating power of the cooking mechanism and thereby increase the intensity of boiling, for example, to meet the requirements of a high-heat, simmering cooking mode. In this embodiment, the cooking appliance can continuously monitor the weight change of the contents of the cooking container during the heating process. That is, steps S3301 to S3309 can be executed in a loop and feedback loop to maintain the boiling state of the cooking container to meet the requirements of the cooking mode.

[0069] It should be understood that the term "real-time" data collected in this specification should be understood as data collected during the execution of the corresponding step. For example, the "real-time weight change rate" in step S3301 can be understood as the weight change rate collected during the most recent collection period. "Real-time" here should not be understood as simply data collected continuously. From the perspective of program execution, the data collected "in real time" at the current moment should be data collected during the most recent collection period. For example, if the current moment is outside the collection period, the data collected "in real time" at the current moment should be data collected at the collection period immediately before the current moment. In some embodiments, the specific implementation of step S330 may include: when the contents of the cooking container are in a boiling state, determining a target weight change rate based on the current cooking mode of the cooking appliance, wherein the contents of the cooking container can be in a continuous boiling state when the target weight change rate is met; and controlling the heating power of the cooking mechanism based on the target weight change rate so that the difference between the real-time weight change rate of the cooking container and its contents and the target weight change rate is less than or equal to a preset difference.

[0070] In this embodiment, the cooking appliance may have multiple cooking modes to cook different dishes. The cooking modes may include, for example, long-cooked soup, rich and fragrant soup, braising, hot pot, boiling water, etc. After the contents of the cooking container boil, the heating power controlled by the cooking appliance in different cooking modes is not the same. For example, in the long-cooked soup mode, the soup is usually heated to a boil on high heat (which can be considered as the maximum limit heating power) and then switched to low heat (which can be considered as the minimum limit heating power) to simmer, keeping the soup slightly boiling until the predetermined cooking time is reached. For another example, in the rich and fragrant soup mode, the soup is usually heated to a boil on high heat (which can be considered as the maximum limit heating power) and then switched to medium heat (which can be considered as the middle value between the maximum limit heating power and the minimum limit heating power) to simmer until the predetermined cooking time is reached. Therefore, in this embodiment, since the weight change rate represents the boiling state of the cooking container's contents, to ensure that the boiling state of the cooking container's contents meets the requirements of the corresponding dish, each cooking mode can have a corresponding target weight change rate. The cooking appliance can then look up the corresponding target weight change rate based on the desired cooking mode, thereby obtaining the corresponding target heating power. Specifically, the cooking appliance's processor or memory can store a cooking table that includes a one-to-one correspondence between multiple cooking modes, target weight change rates, and target powers. After the cooking container's contents boil, the controller / processor determines the cooking mode, retrieves the cooking table stored in the processor or memory, and parses the cooking table to determine the target weight change rate and target power corresponding to the cooking mode, thereby controlling the operation of the cooking mechanism according to the target power.

[0071] As an example, the cooking correspondence table may be shown in Table 1 below:

[0072] Table 1 Cooking correspondence table

[0073]

[0074] Specifically, the controller / processor parses code 001 in the cooking instruction and obtains that the cooking mode is long-cooked soup. By looking up the table, it is found that the corresponding target weight change rate of long-cooked soup is -0.3 and the corresponding target power is 800W.

[0075] Furthermore, after determining the corresponding target power based on the target weight change rate, the cooking appliance controls the cooking mechanism to operate at the target power so that the difference between the real-time weight change rate of the cooking container and its contents and the target weight change rate is less than or equal to a preset difference. In order to ensure that the real-time weight change rate of the cooking container and its contents remains substantially equal to the target weight change rate, the cooking appliance may perform feedback control. Figure 7 The cooking appliance may further perform the following steps S3311 to S3319:

[0076] Step S3311: while the contents of the cooking container are in a boiling state, obtaining a real-time weight change rate of the cooking container and its contents;

[0077] Step S3313, determining whether the difference between the real-time weight change rate and the target weight change rate is less than or equal to a preset difference;

[0078] Step S3315: If the difference between the real-time weight change rate and the target weight change rate is less than or equal to the preset difference, the current heating power is maintained unchanged;

[0079] In step S3317, if the difference between the real-time weight change rate and the target weight change rate is greater than a preset difference, the heating power of the cooking mechanism is determined based on the relationship between the real-time weight change rate and the target weight change rate. For example, if the real-time weight change rate is greater than the target weight change rate, indicating that the actual boiling level is less than the expected boiling level, a third target power is determined and the cooking mechanism is controlled to operate at the third target power, where the third target power is greater than the current heating power. If the real-time weight change rate is less than the target weight change rate, indicating that the actual boiling level is greater than the expected boiling level, a fourth target power is determined and the cooking mechanism is controlled to operate at the fourth target power, where the fourth target power is greater than the current heating power. In this embodiment, the cooking appliance can continuously monitor the weight change of the contents of the cooking container during the heating process. That is, steps S3311 to S3317 can be executed in a loop and feedback loop to ensure that the difference between the real-time weight change rate of the cooking container and its contents and the target weight change rate is less than or equal to the preset difference, thereby maintaining the boiling state of the cooking container to meet the dish requirements of the cooking mode.

[0080] In summary, the cooking control method for a cooking appliance provided in this embodiment can determine the weight change rate of a cooking container and its contents based on multiple weight data. Since the weight change rate represents the weight change of the cooking container and its contents over time, the result obtained by determining the boiling state of the contents of the cooking container based on the weight change rate in this method is more accurate. Furthermore, the method provided in this embodiment can also adjust the heating power of the cooking mechanism based on the boiling state of the contents so that the heating power of the cooking mechanism is within an appropriate range, that is, the cooking appliance selects an appropriate cooking mode and cooks at an appropriate power. Therefore, compared to the prior art, the cooking control method provided in this embodiment of the application does not need to detect the temperature of the contents of the cooking container to determine whether the contents are boiling. Instead, it determines whether the contents are boiling by detecting the weight data of the cooking container and its contents located on the supporting platform. This has the beneficial effects of accurate detection results, rapid control response, safe use, and a good user experience. In addition, the cooking appliance using the above cooking method can determine the boiling state of the contents of the cooking container based on weight, and automatically select the appropriate cooking mode (for example, different cooking modes represented by the size of the cooking fire), thereby automatically adjusting the cooking power, avoiding excessive boiling during the cooking process, thereby reducing the occurrence of accidents and improving the safety of users during the cooking process.

[0081] See also Figure 8 , Figure 8 A flowchart of another cooking control method provided by an embodiment of the present application is shown, which is applicable to the cooking appliance provided by any of the above embodiments. The method includes the following steps S410 to S450.

[0082] Step S410: During the cooking process, obtain the weight change of the cooking container and its contents.

[0083] Step S420: Determine the boiling state of the contents of the cooking container according to the weight change.

[0084] In some embodiments, the specific implementation of step S410 and step S420 can refer to step S310 and step S320 in the above embodiment. To save space, this specification does not elaborate on them.

[0085] Step S430: During the cooking process, a weight curve of the cooking container and its contents changing with time is obtained.

[0086] The weight curve of the cooking container and its contents over time is a curve of the weight of the cooking container and its contents over time drawn with time as a variable (see Figure 9(See the "weight curve" shown in the figure). It should be understood that the above curve can be a fitted curve formed by fitting discrete weight data points based on multiple weight data collected during a preset period and the corresponding collection times. At any moment, the slope of the above weight curve represents the weight change rate of the cooking container and its contents at that moment. The magnitude of the weight change rate can indicate the boiling state or boiling intensity of the contents of the cooking container at that moment.

[0087] Step S440: When the weight curve shows an inflection point and rises, the cooking mechanism is controlled to increase the heating power or to maintain the cooking mechanism operating at the maximum limit power.

[0088] The rise in the inflection point of the weight curve indicates that the weight of the cooking container and its contents has suddenly increased, which is reflected in the steep increase in the slope of the weight curve (see Figure 9 (See inflection point A in Figure 2 , where inflection point A is the rising inflection point.) For example, in a hot pot setting, when a user adds water or new ingredients to the cooking container, the cooking appliance controls the cooking mechanism to increase the heating power or maintain the cooking mechanism at its maximum power limit, accelerating the cooking of the newly added ingredients and facilitating their rapid cooking for consumption.

[0089] Specifically, the determination of "an inflection point rise in the weight curve" can be made based on the relationship between the weight change value ΔG of the cooking container and its contents within a preset period (duration) T and the standard weight increase value G0. The weight change value ΔG of the cooking container and its contents within the preset period (duration) T is equal to the weight of the cooking container and its contents at the end of the preset period T minus the weight of the cooking container and its contents at the beginning of the preset period. For example, when ΔG = 100g, it indicates that the weight of the cooking container and its contents increased by 100g within the preset period T. The standard weight increase value G0 is a fixed positive value used for comparison with the weight change value ΔG. If ΔG > G0, it indicates that the weight of the cooking container and its contents has suddenly increased beyond the marked value, i.e., an inflection point rise has occurred in the weight curve of the cooking container and its contents. If ΔG ≤ G0, it indicates that the weight of the cooking container and its contents has not suddenly increased beyond the standard value, i.e., an inflection point rise has not occurred in the weight curve of the cooking container and its contents. As a specific example, when ΔG = 100g and G0 = 20g, since ΔG > G0, it can be determined that the weight curve of the cooking container and its contents has reached an inflection point. At this point, the cooking appliance needs to increase the heating power of the cooking mechanism or adjust it to the maximum power limit. The "maximum power limit" refers to the maximum heating power that the cooking mechanism can achieve under normal operation.

[0090] Based on this, in step S440 of this embodiment, as an example, the cooking appliance may further perform the following steps S4401 to S4404:

[0091] Step S4401: Obtaining a weight change value of the cooking container and its contents within a preset period;

[0092] Step S4402: Determine the relationship between the weight change value and the weight increase standard value;

[0093] Step S4403: If the weight change value is greater than the weight increase standard value, the cooking mechanism is controlled to increase the heating power or maintain the cooking mechanism operating at the maximum limit power;

[0094] Step S4404: If the weight change value is less than or equal to the weight increase standard value, the current heating power of the cooking mechanism is maintained unchanged.

[0095] For example, when the weight change value is greater than the weight increase standard value, it means that the user has added water or new ingredients into the cooking container. At this time, the cooking appliance adjusts the heating power of the cooking mechanism to increase or adjusts the cooking mechanism to operate at the maximum limit power, which can facilitate the rapid cooking of the newly added ingredients so that the user can eat them as soon as possible; when the weight change value is less than or equal to the weight increase standard value, it means that the weight change of the cooking container and its contents is within the normal variation range outside of human interference, and the cooking appliance does not need to adjust the heating power of the cooking mechanism.

[0096] In this embodiment, during the heating process, the cooking appliance can continuously monitor the weight changes of the cooking container and its contents, that is, the above-mentioned steps S4401 to S4404 can be executed in a loop and feedback manner to monitor in real time whether the weight of the cooking container and its contents increases sharply, thereby adjusting the heating power of the cooking mechanism to meet cooking needs.

[0097] Step S450: When the contents of the cooking container are in a boiling state, if the weight curve shows an inflection point and decreases, the cooking mechanism is controlled to reduce the heating power or to maintain the cooking mechanism operating at a minimum limit power.

[0098] The inflection point of the weight curve decreases when the weight of the cooking container and its contents decreases suddenly, which is reflected on the weight curve as a steep decrease in the slope of the weight curve (see Figure 9 (The inflection point B shown in the figure is the descending inflection point.) For example, in a hot pot scenario, when the user removes ingredients from the cooking container, the ingredients are cooked. At this point, the cooking appliance controls the cooking mechanism to reduce the heating power or maintain the cooking mechanism at the minimum power limit. This prevents the ingredients from becoming overcooked and degrading the taste, while also saving energy and preventing safety accidents caused by overboiling.

[0099] Specifically, the determination of "a weight curve showing an inflection point decrease" can be made based on the relationship between the weight change value ΔG of the cooking container and its contents within a preset period (duration) T and the weight reduction standard value G1. The weight change value ΔG of the cooking container and its contents within the preset period (duration) T is equal to the weight of the cooking container and its contents at the end of the preset period T minus the weight of the cooking container and its contents at the beginning of the preset period. For example, when ΔG = -100g, it indicates that the weight of the cooking container and its contents decreased by 100g within the preset period T. The weight reduction standard value G1 is a fixed negative value used for comparison with the weight change value ΔG. If ΔG < G1, it indicates that the weight of the cooking container and its contents suddenly decreased by more than the standard value, i.e., the weight curve of the cooking container and its contents showed an inflection point decrease. If ΔG ≥ G1, it indicates that the weight of the cooking container and its contents did not suddenly decrease by more than the standard value, i.e., the weight curve of the cooking container and its contents did not show an inflection point decrease. As a specific example, when ΔG = -100g and G1 = -20g, since ΔG < G1, it can be determined that the weight curve of the cooking container and its contents has reached a downward inflection point. In this case, the cooking appliance needs to adjust the heating power of the cooking mechanism to a lower level or to the minimum power limit. The "minimum power limit" refers to the minimum heating power that the cooking mechanism can achieve under normal operation.

[0100] Based on this, in step S450 of this embodiment, as an example, the cooking appliance may further perform the following steps S4501 to S4504:

[0101] Step S4501: Obtaining a weight change value of the cooking container and its contents within a preset period;

[0102] Step S4502: Determine the relationship between the weight change value and the weight reduction standard value;

[0103] Step S4503: If the weight change value is less than the weight reduction standard value, the cooking mechanism is controlled to reduce the heating power or maintain the cooking mechanism operating at the minimum limit power;

[0104] Step S4504: If the weight change value is greater than or equal to the weight increase standard value, the current heating power of the cooking mechanism is maintained unchanged.

[0105] For example, when the weight change value is less than the weight increase standard value, it means that the user has taken out the ingredients from the cooking container, that is, the ingredients in the cooking container have been cooked and are in an edible state. At this time, the cooking utensil adjusts the heating power of the cooking mechanism to reduce it or adjusts the cooking mechanism to operate at the minimum limit power, which can avoid overcooking of the ingredients and reduce the user's eating experience; when the weight change value is greater than or equal to the weight increase standard value, it means that the weight change of the cooking container and its contents is within the normal variation range outside of human interference, and the cooking utensil does not need to adjust the heating power of the cooking mechanism.

[0106] In this embodiment, during the heating process, the cooking appliance can continuously monitor the weight changes of the cooking container and its contents, that is, the above-mentioned steps S4501 to S4504 can be executed in a loop and feedback to monitor in real time whether the weight of the cooking container and its contents has dropped sharply, thereby adjusting the heating power of the cooking mechanism to reduce it to meet cooking needs.

[0107] In summary, the cooking control method for a cooking appliance provided in this embodiment can determine the boiling state of the cooking container's contents based on changes in the weight of the cooking container and its contents, allowing for corresponding adjustments to the heating power of the cooking mechanism. Furthermore, when the weight of the cooking container and its contents increases or decreases dramatically, the cooking appliance can automatically adjust the heating power of the cooking mechanism to suit different usage scenarios. This eliminates the need for the user to manually adjust the heating power, saving energy, reducing safety incidents, and improving the user experience.

[0108] In some other embodiments, the cooking control method may further include:

[0109] Step S460: During the cooking process, if the weight curve continuously changes, the cooking mechanism is controlled to increase the heating power or to maintain the cooking mechanism operating at the maximum limit power.

[0110] Here, "continuous changes in the weight curve" should be understood as: within a certain period of time, the weight curve experiences at least one upward inflection point and at least one downward inflection point, with these upward and downward inflection points alternating. "Constant period of time" refers to a period of time that is numerically equal to an integer multiple of at least two of a preset period. Based on these changes in the weight curve, it can be determined that the user is cooking or blanching food. When cooking, the weight of the cooking container and its contents will continuously change due to the user constantly stirring the ingredients. When blanching food, the weight of the cooking container and its contents will also continuously change due to the constant movement of ingredients in and out of the cooking container. Therefore, when the cooking container detects continuous changes in the weight curve, it can automatically adjust and increase the heating power of the cooking mechanism, thereby facilitating rapid heating and cooking of the food in the cooking container.

[0111] Based on this, in step S460 of this embodiment, as an example, the cooking appliance may further perform the following steps S4601 to S4604:

[0112] Step S4601: Obtaining the maximum weight change and the minimum weight change of the cooking container and its contents within a certain period of time;

[0113] Among them, the "maximum value of weight change" should be understood as: the maximum value of the weight change value of each preset period in the preset period contained in a certain time length; the "minimum value of weight change" should be understood as: the minimum value of the weight change value of each preset period in the preset period contained in a certain time length.

[0114] Step S4602: Determine the relationship between the maximum weight change and the standard weight increase value, and determine the relationship between the minimum weight change and the standard weight decrease value;

[0115] Step S4603: If the maximum weight change is greater than the weight increase standard value, and the minimum weight change is less than the weight decrease standard value, the cooking mechanism is controlled to increase the heating power or maintain the cooking mechanism operating at the maximum limit power;

[0116] Step S4604: If the maximum value of the weight change is less than or equal to the weight increase standard value, or the minimum value of the weight change is greater than or equal to the weight decrease standard value, the current heating power of the cooking mechanism is maintained unchanged.

[0117] For example, when the maximum weight change is greater than the standard weight increase value, and the minimum weight change is less than the standard weight decrease value, this indicates that the user is cooking or blanching ingredients. In this case, the cooking appliance can increase the heating power of the cooking mechanism or adjust the cooking mechanism to operate at its maximum power limit to facilitate rapid cooking of the ingredients. When the maximum weight change is less than or equal to the standard weight increase value, or the minimum weight change is greater than or equal to the standard weight decrease value, this indicates that the weight fluctuation of the cooking container and its contents is within a normal range, excluding human interference, and the cooking appliance does not need to adjust the heating power of the cooking mechanism.

[0118] In summary, the cooking control method for a cooking appliance provided in this embodiment can determine the user's cooking status based on whether the weight of the cooking container and its contents undergoes continuous weight changes, thereby automatically adjusting the heating power of the cooking mechanism to meet the user's cooking needs. Since the user does not need to manually adjust the heating power of the cooking mechanism, cooking is more convenient for the user and the user experience is improved.

[0119] See also Figure 10 , which shows a block diagram of a cooking control device 300 for a cooking appliance provided in an embodiment of the present application. The cooking appliance includes a cooking mechanism for heating a supporting platform, a weight detection device for weighing, a timing device for timing, and a fan assembly for heat dissipation.

[0120] The cooking control device 300 for a cooking appliance includes a weight obtaining module 310 and a boiling state confirming module 320 .

[0121] The weight acquisition module 310 is used to acquire the weight change of the cooking container and its contents during the cooking process. The boiling state confirmation module 320 is used to determine the boiling state of the contents of the cooking container based on the weight change.

[0122] In some embodiments, the cooking control device 300 for a cooking appliance further includes a weight curve acquisition module 330 and a power adjustment module 340. The weight curve acquisition module 330 is configured to acquire a weight curve showing the weight of the cooking container and its contents changing over time during the cooking process. The power adjustment module 340 is configured to control the cooking mechanism to increase heating power or maintain the cooking mechanism at its maximum power limit if the weight curve shows an inflection point, and to control the cooking mechanism to reduce heating power or maintain the cooking mechanism at its minimum power limit if the weight curve shows an inflection point, while the contents of the cooking container are boiling.

[0123] In some embodiments, the weight acquisition module 310 is further configured to acquire multiple weight data of the cooking container and its contents based on a preset period during the cooking process, and determine the weight change rate of the cooking container and its contents based on the multiple weight data. The weight change rate represents the weight change of the cooking container and its contents over time. The boiling state confirmation module 320 is further configured to determine the boiling state of the contents of the cooking container based on the weight change rate. When the weight change rate meets a preset threshold range, the contents of the cooking container are determined to be boiling.

[0124] In some embodiments, the power adjustment module 340 is further configured to adjust the heating power of the cooking mechanism based on the boiling state.
