[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] See also Figure 1 , Figure 1 It is a flow chart of an embodiment of a method for controlling a cooking device of the present application.

[0027] One embodiment of the present application provides a method for controlling a cooking device. The cooking device includes a cooking cavity for placing food to be heated and a heating element for heating the cooking cavity. The method for controlling the cooking device includes the following steps:

[0028] S11: controlling the heating element to perform a first heating operation on the cooking cavity until a first cooking temperature in the cooking cavity reaches a first preset temperature and a first cooking time of the first heating operation reaches a first predetermined time.

[0029] The first heating operation can be understood as a stage in which the cooking cavity and ingredients are slowly heated. The heating element is controlled to perform the first heating operation on the cooking cavity. The heating power of the first heating operation is low, so that the temperature in the cooking cavity slowly reaches a relatively low first preset temperature. The first cooking duration of the first heating operation must also reach the first preset duration. During the first heating operation, the first cooking temperature in the cooking cavity is less than or equal to the first preset temperature. The first cooking temperature may fluctuate within a certain range or remain at the first preset temperature. However, the first heating operation is exited only when the first cooking temperature in the cooking cavity reaches the first preset temperature and the first cooking duration of the first heating operation reaches the first preset duration.

[0030] By controlling the heating element to first perform a first heating operation when cooking food, the ambient temperature and energy supply surrounding the food can be controlled. The first heating operation causes the first cooking temperature within the cooking cavity to reach a lower first preset temperature, and the first cooking duration of the first heating operation lasts for a first predetermined duration. The first preset temperature is lower than the target temperature required for cooking the food. The first heating operation provides sufficient time for heat to diffuse from the exterior of the food to the interior of the food, and for heat to diffuse across different layers within the cooking cavity. This results in uniform temperature diffusion within the cooking cavity, uniform ambient temperature for food at different locations, and more uniform heating of the food inside and outside, thereby ensuring that the food does not crack and that the uniformity of deformation of different food components exceeds a threshold.

[0031] Taking a cooking device such as an oven or other product with a baking function as an example, when the cooking device is used to bake food, according to the cooking mechanism of baked food, at the initial stage of cooking, the baked food will be in a state similar to cake batter. If the cooking device is controlled to heat excessively in the initial stage of cooking, it will cause the height of the cake batter to grow unevenly, and will also cause the surface of the baked food to crack, affecting the cooking effect. The control method of the cooking device of the present application performs a first heating operation at the initial stage of cooking to control the ambient temperature and energy supply around the food, so that the surface of the cake batter rises smoothly. At the same time, the slower heating speed also gives time for the heat on the same level in the cooking cavity to diffuse laterally, so that the ambient temperature of the ingredients at different positions is more uniform, the ingredients do not crack, and the uniformity of the deformation of different ingredients is higher than the threshold, thereby ensuring a better cooking effect.

[0032] Specifically, controlling the heating element to perform a first heating operation on the cooking cavity until a first cooking temperature within the cooking cavity reaches a first preset temperature and a first cooking time of the first heating operation reaches a first predetermined time can include multiple situations: controlling the heating element to perform the first heating operation on the cooking cavity so that the temperature within the cooking cavity reaches the first preset temperature at a predetermined rate from a starting temperature, and the first cooking time required for the cooking cavity to reach the first preset temperature from the starting temperature reaches the first predetermined time; the starting temperature can be room temperature or a preheated temperature after preheating. Alternatively, controlling the heating element to perform the first heating operation on the cooking cavity so that the temperature within the cooking cavity reaches the first preset temperature at a predetermined rate from a starting temperature and is maintained at the first preset temperature until the first cooking time of the first heating operation reaches the first predetermined time. Alternatively, controlling the heating element to perform the first heating operation on the cooking cavity so that the first cooking temperature within the cooking cavity fluctuates within a first temperature range, with the first preset temperature being the maximum value of the first temperature range, until the temperature within the cooking cavity fluctuates to reach the first preset temperature and the first cooking time of the first heating operation reaches the first predetermined time.

[0033] It should be noted that the cooking device further includes a fan element. While controlling the heating element to perform the first heating operation on the cooking cavity, the fan element needs to continue to operate so that the heat in the cooking cavity is evenly diffused.

[0034] S12: Control the heating element to perform a second heating operation on the cooking cavity until the second cooking temperature in the cooking cavity reaches the target temperature and the second cooking time of the second heating operation reaches a second predetermined time, wherein the first preset temperature is lower than the target temperature, and the heating power when the heating element performs the second heating operation on the cooking cavity is greater than the heating power when the heating element performs the first heating operation on the cooking cavity.

[0035] The second heating operation can be understood as a stage for controlling the heating, cooking and shaping of the food in the cooking cavity. The heating element is controlled to perform the second heating operation on the cooking cavity, and the heating power of the heating element in performing the second heating operation on the cooking cavity is greater than the heating power of the heating element in performing the first heating operation on the cooking cavity. During the second heating operation, the second cooking temperature in the cooking cavity rises to fluctuate within a certain range or is maintained at the target temperature, but the exit condition of the second heating operation is that the second cooking temperature in the cooking cavity reaches the target temperature, and at this time the second cooking time of the second heating operation reaches the second predetermined time. The cooking and shaping of the food requires the heating element to continuously maintain a high energy supply to provide the energy required for its phase change and enthalpy change. The second heating operation can provide sufficient heat for the food in the cooking cavity to complete the transformation of the food into cooking and shaping.

[0036] Specifically, controlling the heating element to perform the second heating operation on the cooking cavity until the second cooking temperature in the cooking cavity reaches the target temperature and the second cooking time of the second heating operation reaches the second predetermined time can include multiple situations: controlling the heating element to perform the second heating operation on the cooking cavity so that the second cooking temperature in the cooking cavity increases from the first preset temperature to the target temperature at a higher heating rate and is maintained at the target temperature until the second cooking time of the second heating operation reaches the second predetermined time. Alternatively, controlling the heating element to perform the second heating operation on the cooking cavity so that the temperature in the cooking cavity increases to the target temperature and then fluctuates within a second temperature range, with the minimum value of the second temperature range being greater than or equal to the first preset temperature and the maximum value of the second temperature range being the target temperature, until the temperature in the cooking cavity fluctuates to reach the target temperature and the second cooking time of the second heating operation reaches the second predetermined time.

[0037] After controlling the heating element to perform the first heating operation on the cooking cavity, the temperature at all locations within the cooking cavity has been evenly increased, and the ingredients are evenly heated inside and out, allowing the next cooking stage to begin. This involves controlling the heating element to perform the second heating operation on the ingredients. The heating element continuously maintains a high energy supply, providing the energy required for the ingredients to mature and set. Still taking the example of a product with a baking function, such as an oven, controlling the heating element to perform the second heating operation on the cooking cavity requires continuously maintaining a high energy supply to provide the energy required for the phase and enthalpy changes of the baked ingredients, allowing the baked ingredients to quickly complete the transition from a slurry state to a solid state. The height of the cake batter of the baked food is essentially fixed, and the cake batter has completed solidification and deformation.

[0038] It should be noted that, while controlling the heating element to perform the second heating operation on the cooking cavity, the fan element needs to continue to operate so that the heat in the cooking cavity is evenly diffused.

[0039] The present application adds a first heating operation with a slow temperature increase before the conventional second heating operation, which directly heats the ingredients at the target temperature. The first heating operation is used to provide sufficient time for heat to diffuse from the outside of the ingredients to the inside of the ingredients and for heat to diffuse to different layers within the cooking cavity. This ensures uniform temperature diffusion within the cooking cavity, a more uniform ambient temperature for ingredients at different locations, and more uniform heating of the ingredients inside and outside, thereby ensuring that the ingredients do not break and that the uniformity of the deformation of different ingredients exceeds a threshold. The second heating operation is used to mature and shape the ingredients, requiring a continuous high energy supply to provide the energy required for their phase change and enthalpy change. Since the second heating operation stage primarily plays a role in shaping and maturing the ingredients, the first predetermined duration of the first heating operation is set to be shorter than the second predetermined duration of the second heating operation. This not only ensures uniform heat diffusion and a slow temperature increase within the cooking cavity, but also prevents the first heating operation from being too long, resulting in the ingredients not receiving the high heat supply required for maturation and shaping, causing them to collapse and deform, and prevents the total duration of the cooking control process from being too long.

[0040] In some embodiments, before controlling the heating element to perform a first heating operation on the cooking cavity, the control method includes:

[0041] S10: controlling the heating element to perform a preheating operation on the cooking cavity until the cooking temperature in the cooking cavity reaches a preheating temperature, which is lower than a first preset temperature.

[0042] To ensure more even heat distribution within the cooking cavity and prevent uneven heating of the ingredients, the heating element is controlled to preheat the cooking cavity before placing the ingredients into the cooking cavity, until the cooking temperature within the cooking cavity reaches a preheating temperature, which is less than a first preset temperature. By first heating the cooking cavity to the preheating temperature, the temperature within the cooking cavity is uniform, and then placing the ingredients to be heated into the cooking cavity and executing step S11, the ingredients are heated evenly at all locations within the cooking cavity, facilitating heating of the ingredients.

[0043] In some embodiments, after controlling the heating element to perform a second heating operation on the cooking cavity, the method further includes:

[0044] S13: controlling the heating element to perform a third heating operation on the cooking cavity while maintaining a third preset temperature until a third cooking time of the third heating operation reaches a third predetermined time, wherein the third preset temperature is lower than the target temperature.

[0045] The third heating operation can be understood as a stage for controlling the uniform browning of the ingredients within the cooking cavity. The heating element is controlled to perform the third heating operation on the cooking cavity, with the heating power applied during the third heating operation being greater than the heating power applied during the first heating operation. During the third heating operation, the third cooking temperature within the cooking cavity is maintained at a third preset temperature, which is lower than the target temperature. The third heating operation is terminated when the third cooking duration of the third heating operation reaches a third predetermined duration.

[0046] It should be noted that, while controlling the heating element to perform the third heating operation on the cooking cavity, the fan element needs to continue to operate so that the heat in the cooking cavity is evenly diffused.

[0047] After the second heating operation is completed, the ingredients in the cooking cavity have already cooked and are beginning to color. The ingredients do not need to absorb excessive energy. Excessive heating can result in uneven heating of the surface of the ingredients, leading to localized gelatinization. Therefore, the heating element is controlled to maintain a third preset temperature, lower than the target temperature, during the third heating operation. This allows the heat within the cooking cavity to be gradually evenly distributed under the action of the fan element within the cooking cavity, resulting in a gradual and uniform coloring of the surface of the ingredients, achieving a better cooking effect. Still using the example of a cooking device with a baking function, such as an oven, as the heating element is controlled to perform the third heating operation on the cooking cavity, the cake batter of the baked food has already solidified and is beginning to color. The food does not need to absorb excessive energy. Excessive heating can result in uneven heating of the surface, leading to a tendency for the food to burn. Therefore, during this stage, the third cooking temperature is gradually lowered, and the energy supplied to the heating tube is reduced. This allows the heat within the cavity to be gradually evenly distributed under the action of the fan element, resulting in a gradual and uniform coloring of the surface of the baked food, achieving a better cooking effect.

[0048] It should be noted that before controlling the heating element to perform the first heating operation on the cooking cavity, the control method includes: determining a target temperature and a first preset temperature, and determining a first predetermined time and a second predetermined time based on the type and weight of the food to be heated. The target temperature and weight are positively correlated. A heavier food typically indicates a larger amount and volume, and a higher target temperature is required for heating the food. In some cases, a heavier food also means a longer time required for uniform heat diffusion within the food, a higher first preset temperature, and longer first and second predetermined times. The target temperature, first preset temperature, first predetermined time, and second predetermined time vary depending on the type of food. For example, larger foods like cakes have slower heat diffusion, so the first predetermined time required for the first heating operation is longer; smaller foods like biscuits and bread have faster heat diffusion, so the first predetermined time required for the first heating operation is shorter. When roasting meat, the target temperature, preset temperatures, and predetermined times required for each cooking stage vary depending on the type of meat.

[0049] Specifically, the target temperature T can be selected between 140-220°C depending on the type and weight of the ingredients. The total duration (t) of each heating operation phase other than the preheating operation can be selected between 10-50 minutes depending on the weight of the ingredients. The preheating operation is preset to a temperature T1. When the preset temperature T1 ≥ T-40°C, the preheating operation ends, and both the preheating heating element and the fan element operate at a total power of 1500-3500W. Users can manually enter various cooking data on the cooking device's operating interface, or enter the type and weight of the ingredients into the cooking device, and the cooking device will automatically select the appropriate cooking data.

[0050] See also Figure 2 , Figure 2 This is a schematic diagram of a sub-flow diagram of a first heating operation in an embodiment of a control method for a cooking device of the present application. In some embodiments, controlling the heating element to perform the first heating operation on the cooking cavity until a first cooking temperature within the cooking cavity reaches a first preset temperature and a first cooking duration of the first heating operation reaches a first predetermined duration includes:

[0051] S111: controlling the heating element to perform a first heating operation on the cooking cavity at a first preset power until a first cooking temperature of the cooking cavity reaches a first preset temperature.

[0052] The working time proportions of the heating elements at different preset powers are different. Specifically, the working time proportion of the heating element when working at the first preset power is 13-17s / 30s. The target temperature is T, the first preset temperature can be set to T-15℃, T-20℃ or T-30, etc., and the preheating temperature can be T-40℃. The heating element is controlled to perform the first heating operation on the cooking cavity at the first preset power, and the fan element is kept on working so that the first cooking temperature T2 of the cooking cavity reaches the first preset temperature from the preheating temperature T1. The first preset power, target temperature T and first preset temperature can be selected according to the type and weight of the food.

[0053] S112: Determine whether the first cooking time of the first heating operation is greater than or equal to a first predetermined time.

[0054] Determine whether the first cooking time t2 of the first heating operation is greater than or equal to a first predetermined time. Specifically, the first predetermined time is 8-12 minutes, which can be selected according to the type and weight of the ingredients.

[0055] S113: If the first cooking time is less than the first predetermined time, control the heating element to perform the first heating operation on the cooking cavity at the second preset power until the first cooking temperature drops to the first temperature value, and return to the step of controlling the heating element to perform the first heating operation on the cooking cavity at the first preset power, wherein the second preset power is less than the first preset power.

[0056] The operating time of the heating element when operating at the second preset power accounts for 9-13s / 30s. If the first cooking time t2 is less than the first predetermined time, the heating element is controlled to perform the first heating operation on the cooking cavity at the second preset power, and the fan element is kept on until the first cooking temperature T2 drops to the first temperature value, and the process returns to the step of controlling the heating element to perform the first heating operation on the cooking cavity at the first preset power. Since the first cooking temperature T2 has reached the first preset temperature, but the first cooking time t2 has not yet reached the first predetermined time, in order to prevent the first cooking temperature T2 from exceeding the first preset temperature and affecting the state of the food, the heating operation is performed at a second preset power lower than the first preset power. This can provide heat to the food while lowering the ambient temperature in the cooking cavity. The first temperature value must be less than the first preset temperature but greater than or equal to the preheating temperature. For example, the first temperature value can be selected as T-40°C or T-30°C.

[0057] S114: If the first cooking time is greater than or equal to the first predetermined time, controlling the heating element to perform a second heating operation on the cooking cavity.

[0058] If the first cooking temperature T2 of the cooking cavity reaches the first preset temperature and the first cooking time t2 is greater than or equal to the first predetermined time, the first heating operation is completed and the heating element can be controlled to perform a second heating operation on the cooking cavity.

[0059] See also Figure 3 , Figure 3 This is a schematic diagram of a sub-flow diagram of a second heating operation in an embodiment of a control method for a cooking device of the present application. In some embodiments, controlling the heating element to perform the second heating operation on the cooking cavity until the second cooking temperature within the cooking cavity reaches a target temperature and the second cooking time of the second heating operation reaches a second predetermined time includes:

[0060] S121: controlling the heating element to perform a second heating operation on the cooking cavity at a third preset power until a second cooking temperature of the cooking cavity reaches a target temperature.

[0061] Because the heating element performs the second heating operation, requiring a higher heat supply, the third preset power must be greater than the first and second preset powers. The third preset power can be selected based on the type and weight of the ingredients. The heating element operates at the third preset power for a 30s / 30s split. The target temperature is T. The heating element is controlled to perform the second heating operation in the cooking cavity at the third preset power, while the fan element operates continuously, raising the second cooking temperature T3 in the cooking cavity from the first preset temperature T-20°C to the target temperature T.

[0062] S122: Determine whether the second cooking time of the second heating operation is greater than or equal to a second predetermined time.

[0063] Determine whether the second cooking time t3 of the second heating operation is greater than or equal to a second predetermined time. Specifically, the second predetermined time is 10-14 minutes, which can be selected according to the type and weight of the ingredients.

[0064] S123: If the second cooking time is less than the second predetermined time, control the heating element to perform a second heating operation on the cooking cavity at a fourth preset power until the second cooking temperature drops to a second temperature value, and return to the step of controlling the heating element to perform a second heating operation on the cooking cavity at a third preset power, wherein the fourth preset power is less than the third preset power.

[0065] If the second cooking time t3 is less than the second predetermined time, the heating element is controlled to perform a second heating operation on the cooking cavity at a fourth preset power, and the fan element is continuously operated until the second cooking temperature T3 drops to the second temperature value. The process then returns to the step of controlling the heating element to perform the second heating operation on the cooking cavity at the fourth preset power. Since the second cooking temperature T3 has reached the target temperature, but the second cooking time t3 has not yet reached the second predetermined time, to prevent the second cooking temperature T3 from exceeding the target temperature T and affecting the state of the food, the heating operation is performed at a fourth preset power, which is lower than the third preset power. This provides heat to the food while lowering the ambient temperature within the cooking cavity. The fourth preset power is lower than the third preset power but higher than the first preset power. The operating time of the heating element at the fourth preset power is 16-20 seconds / 30 seconds. The second temperature value must be lower than the target temperature T but higher than the first preheating temperature. For example, the first temperature value can be T-5°C or T-10°C. The second cooking temperature T3 is consistently maintained within a higher temperature range, maintaining a high energy supply for the shaping and cooking of the food.

[0066] S124: If the second cooking time is greater than or equal to the second predetermined time, the heating element is controlled to stop performing the second heating operation on the cooking cavity.

[0067] If the second cooking temperature T3 of the cooking cavity reaches the target temperature T and the second cooking time t3 is greater than or equal to the second predetermined time, the second heating operation is completed, and the heating element can be controlled to stop performing the second heating operation on the cooking cavity and enter the next stage of heating operation at the same time.

[0068] See also Figure 4 , Figure 4 This is a schematic diagram of a sub-flow diagram of the third heating operation of an embodiment of a control method for a cooking device of the present application. In some embodiments, controlling the heating element to perform the third heating operation on the cooking cavity while maintaining the third preset temperature includes:

[0069] S131: Determine whether the third cooking temperature in the cooking cavity is greater than a third preset temperature.

[0070] Determine whether the third cooking time t4 of the third heating operation is greater than or equal to a third predetermined temperature. The third predetermined temperature is lower than the target temperature T. After the second heating operation, the ingredients in the cooking cavity are cooked and begin to color. The ingredients do not need to absorb excessive energy. Therefore, the heating element is controlled to maintain a third predetermined temperature, which is lower than the target temperature, to perform the third heating operation on the cooking cavity. This allows the heat in the cooking cavity to be gradually evenly distributed under the action of the fan element within the cooking cavity, resulting in a gradually evenly colored surface of the ingredients, achieving a better cooking effect. Specifically, the third predetermined temperature is T-5°C or T-8°C, etc., and can be selected based on the type and weight of the ingredients.

[0071] S132: If the third cooking temperature is greater than the third preset temperature, the heating element is controlled to suspend heating.

[0072] If the third cooking temperature T4 is greater than the third preset temperature, the heating element is controlled to suspend heating and the fan element is kept on to work, so as to reduce the third cooking temperature T4 and maintain it at the third preset temperature.

[0073] S133: If the third cooking temperature is less than or equal to the third preset temperature, control the heating element to perform a third heating operation on the cooking cavity at a fifth preset power, where the fifth preset power is greater than the heating power when the heating element performs the first heating operation on the cooking cavity.

[0074] If the third cooking temperature T4 is less than or equal to the third preset temperature, the heating element performs a third heating operation on the cooking cavity at a fifth preset power, and the fan element operates continuously to raise the third cooking temperature T4 to maintain it at the third preset temperature. The fifth preset power is greater than the heating power used by the heating element during the first heating operation. Furthermore, the fifth preset power is greater than the fourth preset power and less than the third preset power. Specifically, the operating time of the heating element at the fifth preset power is 18-22 seconds / 30 seconds, and can be selected based on the type and weight of the ingredients.

[0075] S134: Determine whether the third cooking time reaches the third predetermined time.

[0076] It is determined whether the third cooking time t4 reaches the third predetermined time to determine whether the third heating operation is completed.

[0077] S135: If the third cooking time reaches a third predetermined time, the heating element is controlled to stop performing the third heating operation on the cooking cavity.

[0078] If the third cooking time t4 reaches the third predetermined time, the third heating operation is completed, and the heating element is controlled to stop performing the third heating operation on the cooking cavity.

[0079] If the third cooking time t4 does not reach the third predetermined time, the third heating operation is not completed, and the process returns to step S131 to determine whether the third cooking temperature T4 in the cooking cavity is greater than the third preset temperature.

[0081] Another embodiment of the present application provides a cooking device 200. The cooking device 200 includes a cooking body, a cooking cavity, a heating element 210, a temperature detection element 220, a fan element 230 and a control device 240. The cooking cavity is arranged in the cooking body for placing food to be heated. The heating element 210 is arranged in the cooking body to heat the cooking cavity. The temperature detection element 220 is arranged in the cooking body to obtain the temperature of the cooking cavity. The fan element 230 is arranged in the cooking body to ventilate the cooking cavity. The control device 240 is arranged in the cooking body and is electrically connected to the heating element 210, the fan element 230 and the temperature detection element 220 to implement the control method of the cooking device in any of the above embodiments. The cooking device 200 of the present application controls the heating element 210 to perform a first heating operation and a second heating operation. The first heating operation has a lower heating power, the first cooking temperature is also lower than the target temperature, and the first heating operation lasts for a first predetermined duration. This controls the ambient temperature and energy supply around the food, providing sufficient time for heat to diffuse from the outside of the food to the inside of the food and for heat to diffuse across different layers within the cooking cavity. This results in uniform temperature distribution within the cooking cavity, a more uniform ambient temperature for food at different locations, and more uniform heating of the food inside and outside, thereby ensuring that the food does not crack and that the uniformity of the deformation of different food ingredients exceeds a threshold. After completing the first heating operation, the heating element 210 is controlled to perform a second heating operation, continuously providing high energy to the food as it cooks and shapes, providing the energy required for phase change and enthalpy change, achieving uniform cooking throughout the cooking device 200 and ensuring a good cooking effect. The cooking device 200 of the present application can also perform a third heating operation, which reduces the energy supply after the food is substantially cooked and shaped, ensuring a uniform energy distribution within the cavity and a gradual, even coloring of the food surface. By coordinating and controlling multiple heating operations, a good cooking effect can be achieved, enhancing the user experience.

[0082] Control device 240 includes an information input module, a calculation module, and a control module. The information input module is used to obtain input instructions generated by user operations. The calculation module is used to calculate the operating mode and operating time of fan element 230 and heater element 210 based on the input instructions and the temperature information detected by temperature detection element 220, and to control the operation of fan element 230 and heater element 210 through the control module.
