The term "and / or" used in this application can be interpreted inclusively or mean any one or any combination. Optionally, "A and / or B" means "any one of the following: A; B; A and B". Additionally, the character " / " in this text generally indicates that the related objects before and after are in an "or" relationship.

[0087] Figure 1 This is a schematic diagram of an application scenario provided for the embodiments of this application. Please refer to Figure 1 , Figure 1 It may include a cooking appliance. The cooking appliance may include a cooker 101 and a heating base 102. The cooker 101 may be connected to the heating base 102 by means of short-range wireless communication connection or contact connection, etc.

[0088] Among them, the cooker 101 may include a pot body, a pot lid, a temperature sensor, and a stirring assembly rotatably connected to the pot lid. The cooker can implement a plurality of preset cooking functions. For example, the cooking functions may be stir-frying, frying, cooking, deep-frying, exploding, braising, steaming, boiling, baking, stewing, simmering, etc. When in use, ingredients can be placed into the pot body, the pot lid is closed on the pot body, the pot body is located on the heating surface of the heating base 102, and the heating base 102 can heat the pot body. The temperature sensor can be arranged at the bottom of the pot body to collect accurate temperature values. The stirring assembly can evenly stir the ingredients in the pot body.

[0089] The heating base 102 can be an induction cooker or a radiant cooker. The heating base 102 can be an electric heating element, etc. The heating base 102 can be used to heat cookware, a health kettle, a rice cooker, a pressure cooker, etc.

[0090] In the related art, multiple intelligent cooking stages can be preset in a cooking device, such as a hot oil stage, a vegetable adding stage, and a stir-frying stage, etc.

[0091] The cooking device can be automatically controlled to complete the preset cooking functions through the control program corresponding to each cooking stage. For the vegetable adding stage, the cooking device can determine whether to perform the vegetable adding operation according to the cooking time, the open / close lid signal, and the temperature change trend before and after vegetable adding.

[0092] During the cooking process, if it is determined that the user has added vegetables based on the cooking time and the open / close lid signal, misjudgment may occur, resulting in a lower cooking effect.

[0093] To solve the above technical problems, the embodiments of the present application provide a control method for a cooking appliance. After detecting that the cooking appliance has dropped from a first preset temperature to a second preset temperature, the cooking appliance is heated with the maximum heating power, and multiple temperatures of the cooking appliance within a preset duration are obtained. Whether the cooking appliance is in the state of having added vegetables is judged according to the preset duration and the multiple temperatures. In this way, it can be initially judged that the cooking appliance is in the state of having added vegetables through the temperature change and enter the precise judgment period. By judging the multiple temperatures within this period, the reliability of the judgment result can be increased, the cooking stage can be controlled more precisely, and the cooking effect is improved.

[0094] Next, the technical solutions shown in the present application will be described in detail through specific embodiments. It should be noted that the following several embodiments can exist independently or be combined with each other. For the same or similar content, it will not be repeated in different embodiments.

[0095] Figure 2 It is a schematic flow chart of a control method for a cooking appliance provided by the embodiments of the present application. The execution subject of the embodiments of the present application can be a cooking appliance or a control device provided in the cooking appliance. The control device can be implemented through software or through a combination of software and hardware. Refer to Figure 2 and this method includes:

[0096] S201. When it is detected that the cooking stage of the cooking appliance switches to the vegetable adding stage, control the heating base to heat the cooking appliance to a first preset temperature.

[0097] The cooking stage can include a hot oil stage, a vegetable adding stage, and a stir-frying stage.

[0098] Among them, the hot oil stage can be used to determine whether to pour cooking oil into the cooking appliance and heat the cooking oil to a certain temperature. The vegetable adding stage can be used to remind the user to add vegetables to the cooking appliance and judge whether to perform the vegetable adding operation on the cooking appliance. The stir-frying stage can be used to stir-fry the food in the cooking appliance.

[0099] The first preset temperature may be a temperature related to the hot oil temperature in the hot oil stage.

[0100] Optionally, the first preset temperature may be the same as the temperature at which the oil is heated to the set temperature in the hot oil stage.

[0101] For example, if the oil needs to be heated to 200 °C in the hot oil stage, after entering the ingredient adding stage, the first preset temperature may be 200 °C.

[0102] The current cooking stage of the cooking appliance can be determined according to the current cooking identifier of the cooking appliance. When the cooking stage of the cooking appliance switches to the ingredient adding stage, control the heating base to heat the cooking utensil and heat the cooking utensil to the first preset temperature.

[0103] S202. After detecting that the current temperature of the cooking utensil is less than or equal to the second preset temperature, control the heating base to heat the cooking utensil and obtain multiple temperatures of the cooking utensil within a preset duration.

[0104] The second preset temperature is less than the first preset temperature.

[0105] The power for controlling the heating base to heat the cooking utensil can be the maximum power, which is not limited here.

[0106] The preset duration can be the duration for accurately determining whether to add ingredients.

[0107] For example, assume the preset duration is 5 seconds. Heat the cooking utensil by adjusting the heating base to the maximum power and start timing, and obtain multiple temperatures of the cooking utensil within 5 seconds.

[0108] The preset temperature difference for ingredient adding can be obtained, and the difference between the first preset temperature and the temperature difference for ingredient adding is determined as the second preset temperature. The current temperature of the cooking utensil is detected in real time to judge whether the current temperature of the cooking utensil is less than the second preset temperature. After detecting that the current temperature of the cooking utensil is less than or equal to the second preset temperature, control the heating base to heat the cooking utensil and obtain multiple temperatures of the cooking utensil within a preset duration.

[0109] S203. According to the preset duration and multiple temperatures, judge whether the cooking utensil is in the state of having added ingredients. If so, switch the cooking stage of the cooking appliance to the stir-frying stage.

[0110] The temperature change data can be determined according to the preset duration and multiple temperatures. According to the temperature change data, judge whether the cooking utensil is in the state of having added ingredients. If so, switch the cooking stage of the cooking appliance to the stir-frying stage; if not, control the heating base to heat the cooking utensil to the first preset temperature.

[0111] Optionally, the following method can be used to determine whether the cooker is in the state of having added ingredients according to a preset duration and multiple temperatures: after the preset duration has passed, obtain the current temperature of the cooker; according to the current temperature, determine whether the current temperature is lower than the preset temperature; if so, determine that the cooker is in the state of having added ingredients; if not, according to the preset duration and multiple temperatures, obtain the lowest temperature within the preset duration, and according to the lowest temperature, determine whether the cooker is in the state of having added ingredients.

[0112] Optionally, after switching the cooking stage of the cooking appliance to the stir-frying stage, cooking processing can be performed. Specifically, it can be done in the following way: obtain the preset stir-frying duration of the cooking appliance; determine the difference between the preset stir-frying duration and the preset duration as the target stir-frying duration; perform cooking processing according to the target stir-frying duration.

[0113] Among them, the preset stir-frying duration can be the duration for the stirring component to stir the ingredients in the cooker.

[0114] For example, assume that the preset stir-frying duration is 3 minutes and the preset duration is 30 seconds, then the target stir-frying duration can be determined to be 2 minutes and 30 seconds, and the cooking appliance performs cooking processing according to the target stir-frying duration of 2 minutes and 30 seconds.

[0115] The control method of the cooking appliance provided in this embodiment, when detecting that the cooking stage of the cooking appliance is switched to the ingredient-adding stage, controls the heating base to heat the cooker to the first preset temperature; after detecting that the current temperature of the cooker is less than or equal to the second preset temperature, controls the heating base to heat the cooker, and obtains multiple temperatures of the cooker within the preset duration, where the second preset temperature is less than the first preset temperature; according to the preset duration and multiple temperatures, determines whether the cooker is in the state of having added ingredients, and if so, switches the cooking stage of the cooking appliance to the stir-frying stage. In this way, it is possible to initially determine whether the cooker is in the state of having added ingredients through temperature changes and enter the precise judgment period. By judging multiple temperatures within this period, the reliability of the judgment result can be increased, the cooking stage can be controlled more precisely, and the cooking effect can be improved.

[0116] Next, in combination with Figure 3 the embodiments shown, the process (S203) of determining whether the cooker is in the state of having added ingredients according to the preset duration and multiple temperatures will be further described in detail.

[0117] Figure 3 is a schematic flowchart of another control method of the cooking appliance provided in the embodiment of the present application. On the basis of the above embodiment, reference can be made to Figure 3 for a detailed description of this method. The method includes:

[0118] S301. After the preset duration has passed, obtain the current temperature of the cooker.

[0119] After a preset duration, the temperature signal sent by the temperature sensor can be obtained, and according to the temperature signal, the current temperature of the cooker can be obtained.

[0120] For example, after a preset duration, the current temperature of the cooker is obtained as 120 °C.

[0121] S302. Determine whether the current temperature is lower than the preset temperature.

[0122] If so, execute S303;

[0123] If not, execute S304.

[0124] The preset temperature can be a pre-set temperature. For example, the preset temperature can be any one of 110 °C - 240 °C.

[0125] It can be determined that when the cooker is heated by the heating base for a preset duration and the current temperature is lower than the preset temperature, the cooker is in the state of having ingredients added, based on the fact that if there are ingredients just added to the cooking pot, an endothermic reaction will occur; when the current temperature is greater than or equal to the preset temperature, it is determined whether the cooker is in the state of having ingredients added according to multiple temperatures within the preset duration.

[0126] For example, assuming the preset temperature is 110 °C, if the current temperature is 100 °C, then the current temperature is lower than the preset temperature, and S303 is executed; if the current temperature is 120 °C, then the current temperature is higher than the preset temperature, and S304 is executed.

[0127] S303. Determine that the cooker is in the state of having ingredients added.

[0128] The state of having ingredients added can indicate that there are ingredients in the cooker.

[0129] S304. Determine the lowest temperature of the cooker within the preset duration and determine the cooking moment corresponding to the lowest temperature.

[0130] Multiple temperatures within the preset duration can be obtained, the lowest temperature can be determined from the multiple temperatures, and the cooking moment corresponding to the lowest temperature can be determined.

[0131] For example, assuming the preset duration is 60 seconds, the lowest temperature of the cooker within the preset duration can be 90 °C, and the cooking moment corresponding to the lowest temperature is the 43rd second.

[0132] S305. Determine the target heating cycle among multiple heating cycles according to the cooking moment.

[0133] The cooking moment can be within the target heating cycle. The heating cycle can include multiple temperatures and the moments corresponding to each temperature. The multiple temperatures can include the initial temperature and the end temperature of each heating cycle.

[0134] The preset duration can be divided into multiple heating cycles according to the period, and the target heating cycle can be determined from the multiple heating cycles according to the cooking time.

[0135] For example, assume that the preset duration is 60 seconds, the duration of each heating cycle is 5 seconds, and the cooking time corresponding to the lowest temperature is the 43rd second. Determine that the target heating cycle is the cycle corresponding to the 41st - 45th seconds.

[0136] S306: Determine the cycle order of the target heating cycle among the multiple heating cycles, and determine whether the cycle order is greater than or equal to the preset order.

[0137] If so, execute S303;

[0138] If not, execute S307.

[0139] The order of each heating cycle can be determined respectively, the cycle order of the target heating cycle among the multiple heating cycles can be determined, and it can be determined whether the cycle order is greater than or equal to the preset order.

[0140] For example, assume that the preset order is 7. If the target heating cycle is the cycle corresponding to the 41st - 45th seconds and the determined cycle order of the target heating cycle is 9, then execute S303; if the target heating cycle is the cycle corresponding to the 21st - 25th seconds and the determined cycle order of the target heating cycle is 5, then execute S307.

[0141] The position before and after the time point corresponding to the lowest temperature can be determined by using the magnitude of the cycle order of the heating cycle. If the cycle order corresponding to the lowest temperature is in a later position, that is, the cycle order is greater than or equal to the preset order; if the cycle order corresponding to the lowest temperature is in an earlier position, that is, the cycle order is less than the preset order. At this time, it can also be determined whether to add ingredients according to at least one heating cycle after the lowest temperature, which can increase the reliability of the determination result, more precisely control the cooking stage, and improve the cooking effect.

[0142] S307: Determine at least one candidate heating cycle from the multiple heating cycles according to the target heating cycle.

[0143] The candidate heating cycle is located after the target heating cycle.

[0144] At least one candidate heating cycle with a cycle order after the target heating cycle can be obtained according to the cycle order of each heating cycle.

[0145] For example, assume that the preset duration is 60 seconds, the target heating period is the period corresponding to the 26th - 30th seconds, and the determined candidate heating periods are: the period corresponding to the 31st - 35th seconds, the period corresponding to the 36th - 40th seconds, the period corresponding to the 41st - 45th seconds, the period corresponding to the 46th - 50th seconds, the period corresponding to the 51st - 55th seconds, and the period corresponding to the 56th - 60th seconds.

[0146] Next, take any one of the at least one candidate heating period as an example.

[0147] S308. Determine the temperature change rate of the candidate heating period according to the initial temperature and the end temperature of the candidate heating period.

[0148] The temperature change result can be determined according to the initial temperature and the end temperature of the candidate heating period, and data processing is performed on the temperature change result to obtain the temperature change rate of the candidate heating period.

[0149] Optionally, the temperature change rate of the candidate heating period can be determined according to the initial temperature and the end temperature of the candidate heating period in the following manner: Determine the difference between the end temperature and the initial temperature as the temperature difference; determine the period duration of the candidate heating period; and determine the ratio of the temperature difference to the period duration as the temperature change rate of the candidate heating period.

[0150] For example, assume that the initial temperature is 120 °C, the end temperature is 135 °C, and the period duration of the candidate heating period is 5 seconds. Then, the temperature difference can be determined to be 15 °C, and the temperature change rate is 3.

[0151] S309. Determine the first quantity of at least one candidate heating period, and determine the target threshold according to the first quantity and the preset coefficient.

[0152] The preset coefficient can be a pre - set coefficient. For example, the preset coefficient can be 0.75.

[0153] The first quantity of at least one candidate heating period can be determined, the product of the first quantity and the preset coefficient can be determined, and this product is used as the target threshold.

[0154] For example, assume that the first quantity is 6 and the preset coefficient is 0.6. Then, the target threshold can be determined to be 3.6.

[0155] S310. Determine the target quantity of the candidate heating period with a temperature change rate less than the preset threshold, and determine whether the target quantity is greater than or equal to the target threshold.

[0156] If so, execute S303;

[0157] If not, execute S311.

[0158] The preset threshold can be a pre-set value. For example, the preset threshold can be 4.

[0159] It is possible to determine whether the temperature change rate corresponding to each candidate heating cycle is less than the preset threshold, and determine the target number of candidate heating cycles with a temperature change rate less than the preset threshold, and determine whether the target number is greater than or equal to the target threshold.

[0160] For example, assume that the target threshold is 3.6 and the preset threshold is 3.5.

[0161] Assume that the temperature change rate of the cycle corresponding to 31-35 seconds is 3.8, the temperature change rate of the cycle corresponding to 36-40 seconds is 3.6, the temperature change rate of the cycle corresponding to 41-45 seconds is 3.4, the temperature change rate of the cycle corresponding to 46-50 seconds is 3, the temperature change rate of the cycle corresponding to 51-55 seconds is 2.9, and the temperature change rate of the cycle corresponding to 56-60 seconds is 2.8.

[0162] Then, the target number of candidate heating cycles with a temperature change rate less than the preset threshold is determined to be 4. Since the target number is greater than the target threshold of 3.6, S303 is executed.

[0163] Assume that the temperature change rate of the cycle corresponding to 31-35 seconds is 3.8, the temperature change rate of the cycle corresponding to 36-40 seconds is 3.7, the temperature change rate of the cycle corresponding to 41-45 seconds is 3.6, the temperature change rate of the cycle corresponding to 46-50 seconds is 3, the temperature change rate of the cycle corresponding to 51-55 seconds is 2.9, and the temperature change rate of the cycle corresponding to 56-60 seconds is 2.8.

[0164] Then, the target number of candidate heating cycles with a temperature change rate less than the preset threshold is determined to be 3. Since the target number is less than the target threshold of 3.6, S311 is executed.

[0165] S311. Control the heating base to heat the cooker to the first preset temperature.
