[0017] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0018] To enable those skilled in the art to better understand the solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] With the development of science and technology, cooking appliances are becoming increasingly intelligent. Most of these appliances use heating elements for cooking, but due to the small heating area of ​​these elements, they are unsuitable for frying or stir-frying. Therefore, these cooking appliances suffer from poor performance in frying and stir-frying.

[0020] To address the aforementioned problems, the inventors, through long-term research, discovered and proposed a control method, device, and cooking appliance for a cooking utensil, as provided in this application. By placing a first heating element and a second heating element at different positions within the heating cavity, and using a temperature detection device to obtain the working temperature within the heating cavity in real time, the cooking time is determined during the cooking appliance's entry into cooking mode. Multiple preset temperatures corresponding to different stages of frying and stir-frying are obtained. Within this cooking time, based on the relationship between the cooking appliance's working temperature and the target values ​​of these preset temperatures for different stages of frying and stir-frying, the heating elements of the cooking appliance are controlled to heat with different heating parameters. This allows for precise control of the heating parameters of the heating elements during frying and stir-frying, enabling accurate temperature control and rapid heating, thus improving the cooking performance and user experience. The specific cooking method will be described in detail in subsequent embodiments.

[0021] Please see Figure 1 The diagram illustrates the structure of a cooking appliance provided in one embodiment of this application. In this embodiment, the cooking appliance 100 may include a housing assembly 10, a frying bucket 20, a first heating element 30, a second heating element 40, and a control assembly 50 (not shown).

[0022] The outer shell assembly 10 has a receiving cavity, in which the frying drum 20 is movably disposed. The frying drum 20 may include a bottom wall and a peripheral wall, wherein the peripheral wall surrounds and connects to the periphery of the bottom wall to form a heating cavity 101 for containing food. A first heating element 30 is disposed in the outer shell assembly 10 and located below the bottom wall; a second heating element 40 is disposed in the outer shell assembly 10 and located at the top of the heating cavity 101. A control component 50 is connected to both the first heating element 30 and the second heating element 40, and is used to control the heating parameters of the first heating element 30 and the second heating element 40, such as heating time and heating power, during the cooking process when the cooking appliance 100 is in cooking mode.

[0023] The cooking appliance 100 can have functions such as frying, stir-frying, and heat preservation. The cooking appliance 100 generates hot air through the first heating element 30 and the second heating element 40, and then rapidly circulates the hot air in a sealed space through a hot air convection system, thereby heating the food. In this embodiment, the cooking appliance 100 can be a cooking appliance with frying / stir-frying functions.

[0024] Among them, according to Figure 1It can be seen that the outer casing assembly 10 provides support. The outer casing assembly 10 includes a bottom cover, side walls, and a top plate. The bottom cover and the top plate are spaced apart in a specified direction. This specified direction refers to the direction perpendicular to the plane where the bottom cover is located. One side of the side wall is connected to the periphery of the bottom cover, and the other side is connected to the periphery of the top plate. The outer casing assembly 10 has a receiving cavity for accommodating the frying bucket 20. The side walls have openings for placing the frying bucket 20 into the receiving cavity.

[0025] In some embodiments, a control panel is provided on the outer surface of the sidewall of the housing assembly 10 or on the surface of the top plate away from the bottom cover. The control panel includes one or more functional controls, including but not limited to a start control, a reservation control, a time setting control, a mode setting control, a food type setting control, etc.

[0026] The frying drum 20 can be movably disposed within the receiving cavity. The frying drum 20 includes a bottom wall and a peripheral wall, the peripheral wall surrounding the periphery connected to the bottom wall to jointly form a heating cavity 101 for containing food.

[0027] The first heating element 30 and the second heating element 40 are used to realize the frying and stir-frying function of the cooking appliance 100. Optionally, the first heating element 30 can be disposed at the bottom of the heating cavity 101 and may include an IH heating element, etc.; the second heating element 40 can be disposed at the top of the heating cavity 101 and may include an IH heating element, etc., without limitation. The first heating element 30 and the second heating element 40 can be the same heating device or different heating devices; the maximum heating power of the first heating element 30 and the second heating element 40 can be the same or different. For example, the first heating element 30 may include an IH with parameters of DC voltage DC220V, 50Hz, and 1500W, and the second heating element 40 may include an IH with parameters of DC220V, 50Hz, and 1500W.

[0028] For example, considering that the food in the fryer 20 is mainly located at the bottom of the fryer 20, while the second heating element 40 is located at the top of the heating chamber and is far away from the food in the fryer 20, in this embodiment, the maximum heating power of the second heating element 40 can be set to be greater than the maximum heating power of the first heating element 30, thereby ensuring that the cooking appliance 100 heats the food and improving the cooking reliability.

[0029] For example, considering that the food in the fryer 20 is mainly located at the bottom of the fryer 20, and the first heating element 30 is located at the bottom of the heating chamber, close to the food in the fryer 20, in this embodiment, the maximum heating power of the first heating element 30 can be set to be greater than the maximum heating power of the second heating element 40, thereby controlling the cooking appliance 100 to heat the food quickly and powerfully, achieving the effect of frying without the need to turn the food over, thus improving the cooking performance of the cooking appliance 100.

[0030] In some embodiments, the first heating element 30 may be disposed within the outer casing assembly 10 corresponding to the bottom wall of the frying bucket 20, and is used to heat the gas in the heating chamber 101 when the cooking appliance 100 is in cooking mode. The second heating element 40 may be disposed corresponding to the heating chamber 101 and fixedly disposed within the outer casing assembly 10 by a fixing structure, and is used to heat the gas in the heating chamber 101 when the cooking appliance 100 is in cooking mode. It should be noted that the fixing structures for fixing the first heating element 30 and the fixing structures for fixing the second heating element 40 may be the same or different.

[0031] Understandably, the first heating element 30 and the second heating element 40 can generate heat over a large area, shortening the heating and frying time of the cooking appliance 100. This allows the food in the heating cavity 101 to be fried without flipping, thus improving the cooking performance of the cooking appliance 100.

[0032] In this embodiment, the control component 50 is connected to the first heating element 30 and the second heating element 40 respectively, and is used to control the heating parameters of the first heating element 30 and the second heating element 40 when the cooking appliance 100 is in the cooking mode.

[0033] In some embodiments, the heating power of the first heating element 30 can be adjusted, and the heating power of the second heating element 40 can also be adjusted. In this embodiment, the heating power and / or heating time of the first heating element 30 and the heating power and / or heating time of the second heating element 40 can be controlled by the control component 50 during the cooking mode of the cooking appliance 100, so as to achieve precise temperature control of the cooking appliance 100 and improve the temperature uniformity in the heating cavity 101.

[0034] In some embodiments, the control component 50 is also connected to a control panel on the housing component 10. Upon receiving an operation signal for any function control, the control panel generates a corresponding electrical signal and sends it to the control component 50. The control component 50 can then control the cooking appliance 100 based on this electrical signal. Optionally, the control component 50 may include a microcontroller unit (MCU).

[0035] Please refer to it again. Figure 1In some embodiments, the cooking appliance 100 may further include a fan 102. The fan 102 is disposed within the housing assembly 10 and located on the side of the heating chamber 101 relative to the second heating element 40, for blowing air into the heating chamber 101 during the cooking mode of the cooking appliance 100. The fan 102 is spaced apart from the second heating element 40 and is also fixedly disposed within the housing assembly 10 by a fixing structure. In some embodiments, the fan 102 may also be used to cause the high-temperature gas generated by the heating of the second heating element 40 to circulate convection within the heating chamber 101, thereby heating the food. It should be noted that the fixing structure for fixing the second heating element 40 and the fixing structure for fixing the fan 102 may be the same or different.

[0036] The fan 102 can be driven by a motor to rotate the fan blades and blow air. It can include multiple speed settings, such as high speed (speed above 2500 rpm / min), medium speed (speed between 1500 and 2500 rpm / min), and low speed (speed below 1500 rpm / min). For example, the fan 102 can include a fan with parameters of DC220V, 50Hz, and 100W.

[0037] In the case where the cooking appliance 100 includes a fan 102, the control component 50 is connected to the fan 102 and is used to control the operating parameters of the fan 102, such as controlling the speed and duration of the fan 102.

[0038] In some embodiments, considering that the fan 102 is located on the side of the heating chamber 101 relative to the second heating element 40, the fan 102 can accelerate the heat dissipation of the second heating element 40 and accelerate the air flow in the heating chamber 101, thereby improving the temperature uniformity in the heating chamber 101 and improving the frying and stir-frying performance of the cooking appliance.

[0039] In some embodiments, the cooking appliance 100 may also include a temperature detection device 60 (not shown in the figure), wherein the temperature detection device 60 can be used to detect the working temperature inside the heating cavity 101, so that the cooking appliance 100 can adjust the heating parameters of the heat source in the cooking mode according to the working temperature, thereby improving the accuracy of temperature control of the cooking appliance 100 and improving the frying and stir-frying performance of the cooking appliance 100.

[0040] Please refer to it again. Figure 1In some embodiments, the temperature detection device 60 may include a first temperature detection device 103 and a second temperature detection device 104. The first temperature detection device 103 can be used to detect a first measured temperature near the first heating element 30, and the second temperature detection device 104 can be used to detect a second measured temperature near the second heating element 40. The first and second measured temperatures can be used as the operating temperature of the heating chamber 101, or the operating temperature of the heating chamber 101 can be obtained from the first and second measured temperatures. The first temperature detection device 103 can be disposed below the bottom wall of the frying drum 20 to detect the temperature of the bottom wall; the second temperature detection device 104 can be disposed in the outer shell assembly 10 and above the heating chamber 101 to detect the temperature above the heating chamber 101.

[0041] The first temperature detection device 103 may include a thermocouple detection circuit, a thermistor NTC detection circuit, etc., and the second temperature detection device 104 may include a thermocouple detection circuit, an NTC detection circuit, etc. The first temperature detection device 103 and the second temperature detection device 104 may be the same or different, and no limitation is made here.

[0042] When the cooking appliance 100 includes a first temperature detection device 103 and a second temperature detection device 104, the first temperature detection device 103 can be connected to the control component 50 to detect the temperature near the first heating element 30, such as the temperature at the bottom of the heating cavity 101, and report this temperature as a first measured temperature to the control component 50. The second temperature detection device 104 can be connected to the control component 50 to detect the temperature near the second heating element 40, such as the temperature at the top of the heating cavity 101, and report this temperature as a second measured temperature to the control component 50.

[0043] The control component 50 can obtain the working temperature inside the heating chamber 101 based on the first measured temperature and / or the second measured temperature; and adjust the heating parameters of the first heating element 30 and the second heating element 40 according to the working temperature, thereby achieving precise temperature control of the heating chamber 101 and improving the temperature uniformity in the heating chamber 101.

[0044] In some embodiments, the first temperature detection device 103 may include an NTC detection circuit, and the second temperature detection device 104 may include an NTC detection circuit to detect the operating temperature inside the heating cavity 101 based on the NTC detection circuit.

[0045] In some implementations, the control component 50 can execute the cooking process after receiving a cooking command. The cooking process control component 50 can respond to the cooking appliance 100 entering the cooking mode, determine the cooking time, and within the cooking time, detect the working temperature in the heating cavity 101 through the temperature detection device 60, and obtain multiple preset temperatures corresponding to different stages of frying and stir-frying cooking by the cooking appliance 100. Based on the target magnitude relationship between the working temperature and the multiple preset temperatures, the heating parameters of the first heating element 30 and the second heating element 40 are controlled so that the cooking appliance 100 can achieve the frying and stir-frying effect without flipping the food in the heating cavity 101, thereby improving the cooking performance of the cooking appliance 100 and enhancing the user experience.

[0046] Please see Figure 2 , Figure 2 A flowchart illustrating a control method for a cooking appliance according to an embodiment of this application is shown. This method involves placing a first heating element and a second heating element at different positions within a heating cavity. The operating temperature within the heating cavity is acquired in real time via a temperature detection device. During the cooking process, the cooking time is determined, and multiple preset temperatures corresponding to different stages of frying / stir-frying are obtained. Within this cooking time, based on the relationship between the operating temperature of the cooking appliance and the target values ​​of the multiple preset temperatures for different stages of frying / stir-frying, the heating elements of the cooking appliance are controlled to heat with different heating parameters. This allows for precise control of the heating parameters of the heating elements during frying / stir-frying, enabling rapid and powerful heating, improving the cooking performance and enhancing the user experience. In specific embodiments, this cooking method can be applied to, for example... Figure 5 The control device 200 of the cooking appliance shown and the cooking appliance 100 equipped with the control device 200 of the cooking appliance are shown. Figure 6 The following will use cooking utensils as an example to discuss... Figure 2 The process shown will be described in detail, and the control method of the cooking appliance may specifically include the following steps:

[0047] Step S110: In response to the cooking appliance entering the cooking mode, determine the cooking time.

[0048] In some embodiments, the cooking appliance may include operating modes such as a cleaning mode, a cooking mode, a keep-warm mode, and a standby mode. In cooking mode, the cooking appliance can cook food placed inside. In standby mode, the components of the cooking appliance are in a standby state, and the appliance can receive control commands input by the user and switch operating modes based on these commands. For example, in standby mode, the cooking appliance can receive a first cooking command input by the user and, in response to the first cooking command, cook the food placed inside.

[0049] The cooking methods used by cooking utensils to cook food can include stewing, air frying, pan-frying, baking, etc.

[0050] As one feasible approach, the cooking appliance can receive a first frying / stir-frying instruction input by the user, wherein the first frying / stir-frying instruction may carry a cooking time. Accordingly, upon receiving the first frying / stir-frying instruction, the cooking appliance can determine that it needs to enter a cooking mode. Furthermore, the cooking appliance can parse the first frying / stir-frying instruction to obtain the cooking time carried by the instruction, and within the cooking time, control the heating parameters of the heating element included in the cooking appliance to fry / stir-fry the food.

[0051] As another feasible approach, the cooking time for air frying / stir-frying is fixed. The cooking appliance can receive a second stir-frying / stir-frying command input by the user, wherein the second stir-frying / stir-frying command does not include a cooking time. Accordingly, upon receiving the second stir-frying / stir-frying command, the cooking appliance can determine that it needs to enter the cooking mode, and within the fixed cooking time, the cooking appliance can control the heating parameters of the heating element included in the cooking appliance to stir-fry / stir-fry the food.

[0052] The cooking appliance can determine the cooking time in response to being in cooking mode. Optionally, the cooking time can be set by the user or obtained through third-party experimental data, such as 30 minutes, 40 minutes, 50 minutes, etc., which is not limited here.

[0053] As another feasible approach, the cooking appliance can receive a third stir-frying instruction input by the user, wherein the third stir-frying instruction may carry the type of food to be cooked. Accordingly, upon receiving the third stir-frying instruction, the cooking appliance can determine that it needs to enter the cooking mode. Furthermore, the cooking appliance can parse the third stir-frying instruction to obtain the type of food carried by the instruction, and control the heating parameters of the heating element included in the cooking appliance according to the type of food to stir-fry the food.

[0054] As another possible implementation, the cooking appliance may include a weight sensor or a vision sensor; the weight sensor can be used to detect the weight of the food placed in the heating cavity of the cooking appliance, and the vision sensor can be used to detect the volume of the food placed in the heating cavity of the cooking appliance. The cooking appliance may also receive a fourth stir-fry command input by the user, which may include a type of uncooked food. Accordingly, upon receiving the fourth stir-fry command, the cooking appliance can determine that it needs to enter cooking mode; the cooking appliance can obtain the weight of the food placed in the heating cavity in response to the fourth stir-fry command and determine the food type based on the weight; the cooking appliance can also obtain the volume of the food placed in the heating cavity in response to the fourth stir-fry command and determine the food type based on the volume. Accordingly, the cooking appliance can control the heating parameters of the heating element included in the cooking appliance according to the food type to stir-fry the food.

[0055] Among them, the cooking utensil can determine the type of food to be cooked in response to the cooking mode of the cooking utensil, such as vegetables, meat, fish and shrimp, etc., without limitation.

[0056] For example, a cooking appliance may include cooking modes, a keep-warm mode, and a cleaning mode. Cooking modes may include functions such as stir-frying, air-frying, and stewing. The stir-frying function can be used to stir-fry foods such as fish, meat, ribs, and vegetables. Different preset temperatures can correspond to different stages of stir-frying for different food types. Users can press the button corresponding to the cooking mode and select the desired food type from multiple options within the stir-frying menu. Users can also input a cooking time and press the button for that cooking mode again to activate it. The cooking appliance can also enter a cooking mode after receiving the user-set cooking time and food type, and adjust the heating parameters of its heating element within that time based on the food type to stir-fry the food.

[0057] The cooking appliance may include indicator lights corresponding to frying and stir-frying menu functions. Accordingly, the cooking appliance may illuminate the indicator light after entering the cooking mode. Optionally, the cooking appliance may also display the time when the cooking appliance enters the cooking mode on the screen included with the cooking appliance, and may also display a frying / stir-frying countdown on the screen included with the cooking appliance based on the cooking time and the duration of the cooking mode.

[0058] Step S120: During the cooking time, the working temperature inside the heating chamber is detected by the temperature detection device.

[0059] In some embodiments, after determining the cooking time, the cooking appliance can detect the operating temperature inside the heating cavity using a temperature detection device within that cooking time. Specifically, within the cooking time, the cooking appliance can detect a first measured temperature near the first heating element using a first temperature detection device, and this first measured temperature can be used as the operating temperature inside the heating cavity; alternatively, the cooking appliance can detect a second measured temperature near the second heating element using a second temperature detection device, and this second measured temperature can be used as the operating temperature inside the heating cavity.

[0060] In this case, the cooking appliance may also use the average, median, or arithmetic mean of the first measured temperature and the second detected temperature as the working temperature inside the heating cavity.

[0061] In some embodiments, the cooking appliance can display the operating temperature of the heating cavity within the cooking appliance on a screen included in the cooking appliance. Specifically, the cooking appliance can acquire the operating temperature of the heating cavity in real time during cooking mode and display this temperature on the screen included in the cooking appliance to improve the user experience.

[0062] Step S130: Obtain multiple preset temperatures corresponding to different stages of frying and stir-frying cooking using the cooking appliance.

[0063] In some implementations, the cooking appliance can obtain multiple preset temperatures corresponding to different stages of frying and stir-frying from an associated cloud or electronic device via wireless communication technology (such as Bluetooth, WiFi, Zigbee, etc.), or via serial communication technology (such as serial peripheral interface, serial bus interface, etc.) from an associated electronic device.

[0064] In some implementations, the cooking appliance can be pre-set with cooking temperatures corresponding to various types of ingredients. Accordingly, after determining the type of ingredient to be cooked, the cooking appliance can determine multiple preset temperatures corresponding to different stages of frying and stir-frying based on the type of ingredient.

[0065] For example, the cooking process of frying and stir-frying includes a high-heat frying stage, a low-heat simmering stage, and a stage of releasing residual heat naturally. The cooking appliances can be pre-set with different cooking temperatures for various food types. For example, the cooking temperature for stir-frying vegetables can be between 140℃ and 180℃, the cooking temperature for reducing sauce on low heat on vegetables can be between 140℃ and 180℃, and the cooking temperature for cooling down and releasing residual heat on vegetables can be between 120℃ and 170℃. The cooking temperature for stir-frying meat can be between 160℃ and 200℃, the cooking temperature for reducing sauce on meat can be between 160℃ and 200℃, and the cooking temperature for cooling down and releasing residual heat on meat can be between 150℃ and 180℃. The cooking temperature for stir-frying fish and shrimp can be between 150℃ and 180℃, the cooking temperature for reducing sauce on fish and shrimp can be between 150℃ and 180℃, and the cooking temperature for cooling down and releasing residual heat on fish and shrimp can be between 120℃ and 170℃.

[0066] Step S140: Control the heating parameters of the first heating element and the second heating element according to the target size relationship between the working temperature and the plurality of preset temperatures.

[0067] In some embodiments, after the cooking appliance determines the working temperature inside the heating cavity, it can obtain the target magnitude relationship between the working temperature and multiple preset temperatures. Accordingly, the cooking appliance can control the heating parameters of the first heating element and the second heating element included in the cooking appliance according to the target magnitude relationship between the working temperature and the multiple preset temperatures.

[0068] The heating parameters of the first heating element may include heating power, etc. For example, the cooking appliance can control the first heating element to heat based on a first preset power; wherein the first preset power may include the maximum heating power of the first heating element; wherein heating the first heating element at its maximum heating power can be understood as the first heating element heating at full power.

[0069] The heating parameters of the second heating element may include heating power, etc. For example, the cooking appliance can control the second heating element to heat at a second preset power, wherein the second preset power may be less than the maximum heating power of the second heating element.

[0070] In some implementations, the cooking appliance can control the fan to rotate during the cooking mode to circulate hot air and increase the rate of heat flow. For example, during the cooking mode, the fan can be controlled to rotate at a low, medium, or high speed.

[0071] For example, the frying and stir-frying process of a cooking appliance may include a high-heat frying stage, a low-heat sauce reduction stage, and a heat reduction and natural heat release stage. Accordingly, the cooking appliance can perform frying and stir-frying within the specified cooking time and return to standby mode after the cooking time is reached. The preset temperatures corresponding to different stages of frying and stir-frying for different types of ingredients may be different or the same. Multiple preset temperatures may include a first preset temperature, a second preset temperature, and a third preset temperature. The first preset temperature can be used for the high-heat frying stage of the corresponding cooking appliance, the second preset temperature can be used for the low-heat sauce reduction stage of the corresponding cooking appliance, and the third preset temperature can be used for the heat reduction and natural heat release stage of the corresponding cooking appliance. The first preset temperature can be determined according to the type of food being cooked. For example, if the food is leafy greens, the first preset temperature can be in the range of 140℃ to 180℃, the second preset temperature can be in the range of 140℃ to 180℃, and the third preset temperature can be in the range of 120℃ to 170℃; if the food is meat, the first preset temperature can be in the range of 160℃ to 200℃, the second preset temperature can be in the range of 160℃ to 200℃, and the third preset temperature can be in the range of 150℃ to 180℃; if the food is fish or shrimp, the first preset temperature can be in the range of 150℃ to 180℃, the second preset temperature can be in the range of 150℃ to 180℃, and the third preset temperature can be in the range of 120℃ to 170℃.

[0072] The cooking appliance can determine the first measured temperature as the working temperature inside the heating chamber. Accordingly, the cooking appliance can control the heating parameters of the first and second heating elements based on the relationship between the working temperature and multiple preset temperatures. For example, in response to the working temperature not exceeding the first preset temperature, the cooking appliance can control the first heating element to heat at a first preset power, and / or control the second heating element to heat at a second preset power, and control the fan to operate at a first wind speed. This utilizes the heating elements to heat a large area, enabling rapid heating and stir-frying of different types of food, quickly cooking the bottom of the food, and maintaining a certain temperature through the heat generated by the upper heating element to cook the top of the food, thereby achieving the desired stir-frying effect and improving the user experience.

[0073] The second preset power can be determined based on the type of food being cooked, and this second preset power can be less than the maximum heating power of the second heating element. For example, if the food is determined to be leafy greens, the second preset power can be set within 50% to 80% of the maximum heating power of the second heating element; if the food is determined to be meat, the second preset power can be set within 60% to 90% of the maximum heating power of the second heating element; if the food is determined to be fish or shrimp, the second preset power can be set within 40% to 70% of the maximum heating power of the second heating element. The first fan speed can be low, medium, or high, and is not limited here.

[0074] Accordingly, if, after controlling the first heating element to heat at a first preset power, and / or controlling the second heating element to heat at a second preset power, and controlling the fan to run at a first wind speed, the cooking appliance detects that the operating temperature is greater than the first preset temperature for a continuous first duration, or the first heating element heats at the first preset power for a first target duration, or the second heating element heats at the second preset power for a first target duration, then the first heating element can be controlled to heat at a third preset power, and / or the second heating element can be controlled to heat at a fourth preset power, and the fan can be controlled to run at a second wind speed; wherein, the second wind speed can be greater than the first wind speed, so as to fry the food in the heating chamber over a low flame, achieving the effect of slowly reducing the sauce. The fan rotating at the second wind speed can make the heat and temperature in the heating chamber more evenly and for a longer period of time balanced at the boiling critical state, causing the oil to boil on the surface of the food, thus improving the frying performance of the cooking appliance.

[0075] The first heating time can be determined based on the type of food. For example, the first heating time for leafy vegetables can be between 6 and 10 minutes, for meat between 10 and 20 minutes, and for fish and shrimp between 6 and 15 minutes. The third preset power can also be determined based on the type of food. For example, the third preset power for leafy vegetables can be between 30% and 50% of the maximum heating power of the first heating element, for meat between 20% and 60%, and for fish and shrimp between 20% and 50%. The third preset power can be set lower than the first preset power to reduce the sauce in the heating chamber with gentle heat.

[0076] The fourth preset power can be determined according to the type of food. For example, the fourth preset power for leafy vegetables can be in the range of 30% to 50% of the maximum heating power of the second heating element; the fourth preset power for meat can be in the range of 20% to 60% of the maximum heating power of the second heating element; and the fourth preset power for fish and shrimp can be in the range of 20% to 50% of the maximum heating power of the second heating element. The fourth preset power can be set to be lower than the second preset power to reduce the sauce in the heating chamber using a gentler heat.

[0077] The first target time is less than the cooking time, and can be preset in the cooking appliance. This first target time can be set by the user or obtained through third-party experimental data, and is not limited here. The first target time can be used as a criterion for switching the heating program of the cooking appliance from the stir-frying stage to the simmering stage.

[0078] Accordingly, if the cooking appliance controls the first heating element to heat at a third preset power, and / or the second heating element to heat at a fourth preset power, and controls the fan to run at a second wind speed, and detects that the first measured temperature is greater than the second preset temperature for a continuous second duration, or the first heating element heats at the third preset power for a second target duration, or the second heating element heats at the fourth preset power for a second target duration, then the first heating element and / or the second heating element can be controlled to stop heating, and the fan can be controlled to stop rotating, so that the heat in the heating cavity slowly decreases, preventing overheating and causing the food in the heating cavity to burn, thereby improving the performance of frying and enhancing the user experience.

[0079] The second duration can be determined based on the type of food. For example, the second duration for vegetables can be between 1 and 5 minutes, for meats between 2 and 10 minutes, and for fish and shrimp between 1 and 6 minutes.

[0080] Accordingly, if the cooking appliance detects that the first measured temperature is lower than the third preset temperature after controlling the first heating element and / or the second heating element to stop heating, it can control the first heating element to heat at a fifth preset power and / or the second heating element to heat at a sixth preset power. The fifth preset power can be determined based on the type of food, and the sixth preset power can also be determined based on the type of food; wherein the fifth preset power is lower than the first preset power, and the sixth preset power is lower than the second preset power.

[0081] The fifth preset power can be the same as the third preset power, and the sixth preset power can be the same as the fourth preset power. Correspondingly, the detection that the first measured temperature is less than the third preset temperature can be understood as the cooking appliance having completed heat release. Alternatively, controlling the first heating element to heat at the fifth preset power and / or the second heating element to heat at the sixth preset power can be understood as controlling the first heating element to heat at the third preset power and / or the second heating element to heat at the fourth preset power, so that after completing heat release in the residual heat self-heating release stage, the appliance returns to the fine heat reduction stage, thereby improving the frying and stir-frying performance of the cooking appliance.

[0082] The second target duration is less than the cooking time. This second target duration can be the same as or different from the first target duration and can be preset in the cooking appliance. The second target duration can be set by the user or obtained through third-party experimental data; no limitation is made here. The second target duration can serve as a criterion for switching the heating program of the cooking appliance from the low-heat reduction stage to the heat reduction and natural residual heat release stage.

[0083] Accordingly, during the operation of the cooking appliance, the temperature detection device included in the cooking appliance can collect the temperature inside the heating cavity in real time. If the detected temperature exceeds a preset over-temperature protection temperature, the heating load included in the cooking appliance can be controlled to stop heating and an alarm can be triggered. The temperature detection device included in the cooking appliance may include a first temperature detection device that detects the temperature near the first heating element included in the cooking appliance, and may also include a second temperature detection device that detects the temperature near the second heating element included in the cooking appliance. Accordingly, if the cooking appliance detects that the temperature detected by the first temperature detection device exceeds the first over-temperature protection temperature, the heating load included in the cooking appliance can be controlled to stop heating and an alarm can be triggered; if the cooking appliance detects that the temperature detected by the second temperature detection device exceeds the second over-temperature protection temperature, the heating load included in the cooking appliance can be controlled to stop heating and an alarm can be triggered. The first over-temperature protection temperature can be set above 200°C, and the second over-temperature protection temperature can be set above 200°C.

[0084] During the cooking process, if the frying bucket is detected to be removed from the cooking appliance, the appliance can pause cooking and resume cooking once the frying bucket is returned. Users can remove the frying bucket at any time during cooking to add ingredients such as soy sauce and seasonings. These added seasonings puff up upon heating and are evenly distributed over the food by a fan, enhancing the flavor, improving the appliance's performance, and enhancing the user experience.

[0085] The first and second heating elements can be electromagnetic heating elements. Accordingly, it can be understood that the cooking appliance uses the first and second heating elements to generate heat over a large area during the frying and stir-frying process to achieve rapid heating. The fan and temperature detection device work together to precisely control the temperature inside the heating chamber of the cooking appliance. This achieves the frying and stir-frying effect without flipping the food in the cooking appliance, improving the performance of the cooking menu and enhancing the user experience.

[0086] An embodiment of this application provides a control method for a cooking appliance. By placing a first heating element and a second heating element at different positions within the heating cavity, the working temperature within the heating cavity is acquired in real time through a temperature detection device. During the cooking process when the cooking appliance enters the cooking mode, the cooking time is determined, and multiple preset temperatures corresponding to different stages of frying and stir-frying are obtained. Within this cooking time, the heating elements of the cooking appliance are controlled to heat with different heating parameters according to the target magnitude relationship between the working temperature of the cooking appliance and the multiple preset temperatures corresponding to different stages of frying and stir-frying. Thus, the cooking appliance can accurately control the heating parameters of the heating elements during frying and stir-frying to achieve precise temperature control, making the cooking appliance heat up quickly and powerfully, improving the cooking performance of the cooking appliance, and enhancing the user experience.

[0087] Please see Figure 3 , Figure 3 A schematic flowchart of a control method for a cooking appliance according to an embodiment of this application is shown. This method is applied to the aforementioned cooking appliance, and the temperature detection device in the cooking appliance may include a first temperature detection device. The first temperature detection device can be used to detect a first measured temperature near a first heating element. The following will focus on... Figure 3 The process shown will be described in detail, and the control method of the cooking appliance may specifically include the following steps:

[0088] Step S210: In response to the cooking appliance entering the cooking mode, determine the cooking time.

[0089] For a detailed description of step S210, please refer to the previous description of step S110, which will not be repeated here.

[0090] Step S220: During the cooking time, obtain the first measured temperature near the first heating element detected by the first temperature detection device, and determine the first measured temperature as the working temperature.

[0091] In some embodiments, the temperature detection device in the cooking appliance includes a first temperature detection device, wherein the first temperature detection device can be used to detect a first measured temperature near the first heating element. Specifically, the cooking appliance can detect the first measured temperature near the first heating element via the first temperature detection device after determining the cooking time in response to the cooking appliance being in cooking mode, and can determine the first measured temperature as the operating temperature within the heating cavity.

[0092] Step S230: Obtain multiple preset temperatures corresponding to different stages of frying and stir-frying cooking using the cooking appliance, wherein the multiple preset temperatures include a first preset temperature.

[0093] In some embodiments, the cooking appliance may be pre-set with multiple preset temperatures corresponding to different stages of frying and stir-frying; these preset temperatures may correspond to different types of ingredients. Optionally, the cooking appliance may also acquire the type of ingredient in the heating chamber and determine the multiple preset temperatures corresponding to different stages of frying and stir-frying based on the ingredient type. These multiple preset temperatures may include a first preset temperature, a second preset temperature, and a third preset temperature. The first preset temperature may correspond to the high-heat stir-frying stage in the cooking appliance's frying and stir-frying process, the second preset temperature may correspond to the low-heat reducing stage, and the third preset temperature may correspond to the heat reduction and natural release stage during the cooking appliance's frying and stir-frying process.

[0094] The preset temperatures for different stages of frying and stir-frying different types of ingredients can be the same or different. For example, in the stir-frying heating stage: the first preset temperature for leafy vegetables is in the range of 140℃-180℃, the first preset temperature for meat is in the range of 160℃-200℃, and the first preset temperature for fish and shrimp is in the range of 150℃-180℃.

[0095] Step S240: Obtain the type of food in the heating chamber, and determine the second preset power corresponding to the second heating element according to the type of food, wherein the second preset power is less than the maximum heating power of the second heating element.

[0096] In some embodiments, the cooking appliance can acquire the type of food in the heating cavity and determine a second preset power based on the type of food and the corresponding second heating element. Optionally, the cooking appliance can receive a user-inputted food type setting instruction and determine the type of food in the heating cavity based on the instruction; the cooking appliance can also acquire the weight of the food in the heating cavity and determine the food type based on the weight; the cooking appliance can also acquire the volume of the food in the heating cavity and determine the food type based on the volume.

[0097] The second preset power can be less than the maximum heating power of the second heating element. For example, the second preset power for vegetables is in the range of 50% to 80% of the maximum heating power of the second heating element, the second preset power for meat is in the range of 60% to 90% of the maximum heating power of the second heating element, and the second preset power for fish and shrimp is in the range of 40% to 70% of the maximum heating power of the second heating element.

[0098] Step S250: In response to the operating temperature not being greater than the first preset temperature, control the first heating element to heat at the first preset power, and / or control the second heating element to heat at the second preset power.

[0099] In some embodiments, the cooking appliance can acquire a first measured temperature detected by a first temperature detection device in real time and determine the first measured temperature as the working temperature; accordingly, after the cooking appliance determines the working temperature and the first preset temperature, it can compare the working temperature with the first preset temperature to obtain a first magnitude relationship between the first measured temperature and the first preset temperature, and control the heating parameters of the first heating element and the second heating element according to the first magnitude relationship.

[0100] The cooking appliance can control the first heating element to heat at a first preset power and / or control the second heating element to heat at a second preset power in response to the working temperature not exceeding a first preset temperature, so as to use the heating element to heat a large area, realize the rapid heating and stir-frying of different types of fried and stir-fried ingredients, so that the bottom of the ingredients is quickly cooked and the top of the ingredients is cooked through the heat generated by the heating element in the upper part of the heating cavity.

[0101] As one feasible approach, when the cooking appliance includes a fan, the appliance can control the fan to operate at a first wind speed in response to the operating temperature not exceeding a first preset temperature, thereby accelerating the flow of hot air within the heating cavity and improving the temperature uniformity within the heating cavity. The first wind speed can be low, medium, or high, and is not limited thereto.

[0102] In some embodiments, the cooking appliance can determine a first duration based on the type of food, a third preset power corresponding to the first heating element based on the type of food, and a fourth preset power corresponding to the second heating element based on the type of food. Considering that after quickly stir-frying the food, the food needs to be reduced in sauce, the third preset power can be set to be lower than the first preset power, and the fourth preset power can be set to be lower than the second preset power, to allow for gentle stir-frying of the food in the cooking appliance, achieving slow reduction of sauce. Accordingly, after controlling the first heating element to heat at the first preset power and / or controlling the second heating element to heat at the second preset power, if the cooking appliance detects that the operating temperature is higher than the first preset temperature for a continuous first duration, or that the first heating element heats at the third preset power for a second target duration, or that the second heating element heats at the fourth preset power for a second target duration, then the first heating element can be controlled to heat at the third preset power, and / or the second heating element can be controlled to heat at the fourth preset power.

[0103] When the working temperature is greater than the first preset temperature for a continuous first duration, or when the first heating element heats the second target duration at the third preset power, or when the second heating element heats the second target duration at the fourth preset power, it can be understood that the cooking appliance has finished stir-frying. In this case, combining the first duration judgment can improve the accuracy of the cooking appliance's temperature control for stir-frying and improve the cooking appliance's performance for stir-frying.

[0104] As an implementable method, when the cooking appliance includes a fan, the cooking appliance can control the fan to operate at a second wind speed in response to the first measured temperature being greater than a first preset temperature for a first duration, or the first heating element heating at a third preset power for a second target duration, or the second heating element heating at a fourth preset power for a second target duration; wherein the second wind speed can be greater than the first wind speed, for example, the first wind speed is at a low setting and the second wind speed is at a medium setting, so that the heat and temperature in the heating chamber of the cooking appliance are more evenly and for a longer period of time balanced at the critical state of boiling of the food, and the oil continues to boil on the surface of the food under slow heat.

[0105] In some embodiments, the cooking appliance can determine a second duration corresponding to the working temperature based on the type of food, wherein the second duration may be shorter than the first duration. Accordingly, after the cooking appliance controls the first heating element to heat at a third preset power and / or the second heating element to heat at a fourth preset power, if it detects that the working temperature is greater than a second preset temperature for a continuous second duration, or the first heating element heats at the third preset power for a second target duration, or the second heating element heats at the fourth preset power for a second target duration, it can control the first heating element and / or the second heating element to stop heating, so as to utilize the residual heat of the heating chamber in the cooking appliance for food cooking and avoid the food from burning.

[0106] When the working temperature is greater than the second preset temperature for a continuous second duration, or when the first heating element heats the second target duration at the third preset power, or when the second heating element heats the second target duration at the fourth preset power, it can be understood that the cooking appliance has finished reducing the sauce. In this case, combining the second duration judgment can improve the accuracy of the cooking appliance's temperature control for frying and stir-frying, and improve the performance of the cooking appliance for frying and stir-frying.

[0107] As an implementable method, when the cooking appliance includes a fan, the cooking appliance can control the fan to stop rotating in response to the first measured temperature being greater than the second preset temperature for a second duration, or the first heating element heating for a second target duration at a third preset power, or the second heating element heating for a second target duration at a fourth preset power. This causes the heat in the heating chamber of the cooking appliance to decrease slowly, preventing the food from burning and improving the frying performance of the cooking appliance.

[0108] In some embodiments, the cooking appliance can determine a fifth preset power corresponding to the first heating element based on the type of food, and a sixth preset power corresponding to the second heating element based on the type of food; wherein the fifth preset power may be less than the first preset power, and the sixth preset power may be less than the second preset power. Accordingly, after the cooking appliance controls the first heating element and / or the second heating element to stop heating, if it detects that the operating temperature is less than a third preset temperature, it can control the first heating element to heat at the fifth preset power, and / or the second heating element to heat at the sixth preset power.

[0109] As one feasible approach, when the cooking appliance includes a fan, the appliance can control the fan to operate at a third fan speed in response to the operating temperature being lower than a third preset temperature. This third fan speed can be equal to or equal to the first fan speed.

[0110] The cooking appliance controls the first heating element to heat at a fifth preset power, and / or the second heating element to heat at a sixth preset power. This can be understood as the cooking appliance controlling the first heating element to heat at a third preset power, and / or the second heating element to heat at a fourth preset power. In other words, the cooking appliance returns to the low-heat reduction stage, thereby improving the performance of frying and enhancing the user experience.

[0111] The cooking method provided in one embodiment of this application is different from... Figure 2The cooking method shown in this embodiment includes a first temperature detection device for detecting a first measured temperature near the first heating element. This embodiment can also acquire the first measured temperature near the first heating element detected by the first temperature detection device during the cooking time, and determine the first measured temperature as the working temperature. When multiple preset temperatures include the first preset temperature, the type of food in the heating cavity is acquired, and a second preset power corresponding to the second heating element is determined based on the food type. The second preset power is less than the maximum heating power of the second heating element. In response to the working temperature not exceeding the first preset temperature, the first heating element is controlled to heat at the first preset power, and / or the second heating element is controlled to heat at the second preset power. Thus, during the cooking time, the heating parameters of the heating elements included in the cooking appliance are controlled according to the relationship between the working temperature and multiple preset temperatures, as well as the type of food in the heating cavity. This improves the accuracy of temperature control during frying and stir-frying, enhances the performance of the cooking appliance, and improves the user experience.

[0112] Please see Figure 4 , Figure 4 A schematic flowchart of a control method for a cooking appliance according to an embodiment of this application is shown. The method is applied to the aforementioned cooking appliance. The temperature detection device in the cooking appliance includes a first temperature detection device for detecting a first measured temperature near a first heating element. The temperature detection device also includes a second temperature detection device for detecting a second measured temperature near a second heating element. The following will focus on... Figure 4 The process shown will be described in detail, and the control method of the cooking appliance may specifically include the following steps:

[0113] Step S310: In response to the cooking appliance entering the cooking mode, determine the cooking time.

[0114] For a detailed description of step S310, please refer to the previous description of step S110, which will not be repeated here.

[0115] Step S320: During the cooking time, acquire the second measured temperature near the second heating element detected by the second temperature detection device, and determine the second measured temperature as the working temperature; or, during the cooking time, acquire the first measured temperature near the first heating element detected by the first temperature detection device and the second measured temperature near the second heating element detected by the second temperature detection device, and determine the working temperature based on the first measured temperature and the second measured temperature.

[0116] In some embodiments, the temperature detection device may include a first temperature detection device and a second temperature detection device. The first temperature detection device can be used to detect a first measured temperature near a first heating element, and the second temperature detection device can be used to detect a second measured temperature near a second heating element. The cooking appliance can use either the first or second measured temperature as the operating temperature of the heating cavity, or it can obtain the operating temperature of the heating cavity based on both the first and second measured temperatures. Optionally, the cooking appliance can obtain the difference between the first and second measured temperatures. If the difference is greater than a preset difference, the operating temperature of the heating cavity can be obtained based on the first and second measured temperatures; if the difference is less than or equal to the preset difference, either the first or second measured temperature can be used as the operating temperature of the heating cavity.

[0117] The cooking appliance obtains the working temperature of the heating chamber based on the first and second measured temperatures, which can be the maximum, minimum, or average value of the first and second measured temperatures.

[0118] Step S330: Obtain multiple preset temperatures corresponding to different stages of frying and stir-frying using the cooking appliance.

[0119] Step S340: Control the heating parameters of the first heating element and the second heating element according to the target magnitude relationship between the working temperature and the plurality of preset temperatures.

[0120] For a detailed description of steps S330-S340, please refer to the previous description of steps S130-S140, which will not be repeated here.

[0121] Step S350: If the first measured temperature is greater than the first over-temperature protection temperature, then control the first heating element and the second heating element to stop heating; or, if the second measured temperature is greater than the second over-temperature protection temperature, then control the first heating element and the second heating element to stop heating.

[0122] In some embodiments, the cooking appliance may be pre-set with an ultra-high temperature protection temperature corresponding to a first temperature detection device, wherein the cooking appliance can obtain the ultra-high temperature protection temperature as a first over-temperature protection temperature; the cooking appliance may be pre-set with an ultra-high temperature protection temperature corresponding to a second temperature detection device, wherein the cooking appliance can obtain the ultra-high temperature protection temperature as a second over-temperature protection temperature.

[0123] Optionally, the user can set a first over-temperature protection temperature based on the pre-set over-temperature protection temperature of the first temperature detection device, or a second over-temperature protection temperature based on the pre-set over-temperature protection temperature of the second temperature detection device. The cooking appliance can obtain the first over-temperature protection temperature corresponding to the first temperature detection device through third-party experimental data, or obtain the second over-temperature protection temperature corresponding to the second temperature detection device through third-party experimental data.

[0124] In some embodiments, while the cooking appliance obtains a first measured temperature and a second measured temperature in real time, it can compare the first measured temperature with a first over-temperature protection temperature, and / or compare the second measured temperature with a second over-temperature protection temperature. If the first measured temperature is greater than the first over-temperature protection temperature or the second measured temperature is greater than the second over-temperature protection temperature, the first heating element and the second heating element can be controlled to stop heating, or all heating loads included in the cooking appliance can be controlled to stop working, so as to perform over-temperature protection treatment on the cooking appliance.

[0125] In some implementations, an alarm message can be generated after all heating loads included in the cooking appliance have stopped operating. The cooking appliance can output this alarm message through indicator lights, buzzers, voice prompts, etc., allowing the user to take appropriate actions based on the alarm message, such as cooling down the cooking appliance or cutting off the power.

[0126] In some implementations, after the cooking appliance controls all heating loads within the appliance to stop operating, if it is determined that both the first and second measured temperatures are below the operating temperature threshold, the cooking appliance can be controlled to return to step S310 to resume the normal cooking process. The operating temperature threshold can be set by the user or obtained from third-party experimental data; it can be preset in the cooking appliance or obtained by the appliance from associated electronic devices or the cloud. For example, the operating temperature threshold can be below 105°C.

[0127] For example, the first temperature detection device includes an NTC detection circuit. Based on third-party experimental data, the over-temperature protection temperature corresponding to the first temperature detection device is above 200°C. Furthermore, the user can set the first over-temperature protection temperature to 200°C based on this over-temperature protection temperature. The second temperature detection device also includes an NTC detection circuit. Based on third-party experimental data, the over-temperature protection temperature corresponding to the second temperature detection device is above 200°C. Furthermore, the user can set the second over-temperature protection temperature to 200°C based on this over-temperature protection temperature. If the cooking appliance detects that the first measured temperature is greater than the first over-temperature protection temperature or the second measured temperature is greater than the second over-temperature protection temperature, it can control all heating loads included in the cooking appliance to stop working. Furthermore, after the heating load of the cooking appliance stops working, the first and second measured temperatures can be detected in real time. If it is determined that both the first and second measured temperatures are less than 105°C, the cooking appliance can continue to operate within the cooking time. Based on the type of food, multiple preset temperatures corresponding to different stages of frying and stir-frying can be determined. Based on the relationship between the working temperature and the target values ​​of multiple preset temperatures, as well as the type of food, the heating parameters of the first and second heating elements can be controlled, thereby ensuring the safety of cooking and improving the performance of frying and stir-frying.

[0128] The cooking method provided in one embodiment of this application is different from... Figure 2 The cooking method shown in this embodiment includes a first temperature detection device for detecting a first measured temperature near the first heating element. The temperature detection device also includes a second temperature detection device for detecting a second measured temperature near the second heating element. In this embodiment, if the first measured temperature is greater than the first over-temperature protection temperature or the second measured temperature is greater than the second over-temperature protection temperature, the first heating element and the second heating element will be controlled to stop heating. When the cooking appliance is used for frying and stir-frying, the safety of cooking is ensured. At the same time, the heating elements of the cooking appliance are controlled to cooperate with heating according to the type of food being cooked, which improves the frying and stir-frying performance of the cooking appliance.

[0129] Please see Figure 5 , Figure 5 A block diagram of a control device for a cooking appliance according to an embodiment of this application is shown. The control device 200 is applied to the cooking appliance provided in an embodiment of this application. The cooking appliance includes a heating chamber, a first heating element, a second heating element, a fan for generating hot air circulation within the heating chamber, and a temperature detection device for detecting the operating temperature within the heating chamber. The following will discuss... Figure 5The process shown is described in detail. The control device 200 of the cooking appliance includes: a cooking time module 210, a working temperature detection module 220, a preset temperature acquisition module 230, and a heating control module 240, wherein:

[0130] The cooking time module 210 is used to determine the cooking time in response to the cooking appliance entering the cooking mode.

[0131] The working temperature detection module 220 is used to detect the working temperature inside the heating cavity through the temperature detection device during the cooking time.

[0132] The preset temperature acquisition module 230 is used to acquire multiple preset temperatures corresponding to different stages of the cooking appliance when it is used for frying and stir-frying.

[0133] The heating control module 240 is used to control the heating parameters of the first heating element and the second heating element according to the target magnitude relationship between the working temperature and the plurality of preset temperatures.

[0134] Further, the temperature detection device includes a first temperature detection device, which is used to detect a first measured temperature near the first heating element; the preset temperature acquisition module 230 may include: a first unit for determining the operating temperature, wherein:

[0135] The first unit for determining the working temperature is used to acquire a first measured temperature near the first heating element detected by the first temperature detection device during the cooking time, and to determine the first measured temperature as the working temperature.
