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.

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.

[0017] With the development of science and technology, air fryers are becoming increasingly intelligent. Most air fryers use heating elements for cooking, but due to the small heating area of ​​these elements, they are unable to stew or have poor stewing performance. Therefore, these cooking appliances suffer from poor stewing performance when stewing food.

[0018] 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 responding to the cooking appliance being in cooking mode, cooking parameters are determined. During cooking mode, based on the relationship between a first measured temperature within the heating chamber and a first preset temperature for stewing, the heating parameters of the heating element within the cooking appliance are controlled. This allows the heating power of the heating element to be flexibly adjusted according to the temperature within the heating chamber during stewing, shortening the stewing time, improving the temperature uniformity within the heating chamber, and enhancing the stewing performance of the cooking appliance. The specific cooking method is described in detail in subsequent embodiments.

[0019] 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).

[0020] 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.

[0021] The cooking appliance 100 can have functions such as stewing 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 a stewing function.

[0022] Among them, according to Figure 1 It 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.

[0023] 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.

[0024] 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.

[0025] The first heating element 30 and the second heating element 40 are used to realize the stewing 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 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.

[0026] 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 power of the second heating element 40 can be set to be greater than the maximum power of the first heating element 30, thereby ensuring that the cooking appliance 100 heats the food and improving the cooking reliability.

[0027] 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 power of the first heating element 30 can be set to be greater than the maximum power of the second heating element 40, thereby shortening the cooking time of the food by the cooking appliance 100 and improving the cooking performance.

[0028] 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.

[0029] The first heating element 30 and the second heating element 40 can both be electromagnetic heating elements, which can heat out a large area of ​​heat, shorten the heating and stewing time of the cooking appliance 100, and improve the uniformity of the heat of the cooking appliance 100.

[0030] 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.

[0031] 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.

[0032] 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).

[0033] Please refer to it again. Figure 1In some embodiments, the cooking appliance 100 may further include a fan 102 for circulating hot air within the heating chamber 101. 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 cooking mode. 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 may be the same as or different from the fixing structure for fixing the fan 102.

[0034] 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.

[0035] 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 fan speed and rotation duration. The fan 102 can fan air during cooking, thereby introducing fresh air into the heating chamber 101, increasing the oxygen content in the heating chamber 101, and improving the taste of the cooked food. The fan 102 can also fan air after cooking has finished, thereby accelerating heat dissipation from the heating chamber 101 and shortening the cooling time of the food.

[0036] In some embodiments, considering that the fan 101 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, shortening the cooking time of the food in the heating chamber 101, and improving the cooking performance of the cooking appliance 100.

[0037] In some embodiments, considering that electromagnetic heating has heat storage properties, the cooking appliance 100 can control the first heating element 30 and the second heating element 40 to stop power supply before the fan 102 at the end of the cooking process, so that the residual heat of the first heating element 30 and the second heating element 40 can be used for heating by the fan 102, which improves the energy saving of the cooking appliance 100 and can also reduce the cooling time of the food.

[0038] 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 chamber 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 stewing performance of the cooking appliance 100.

[0039] Please refer to it again. Figure 1 In 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 understood as a lower temperature detection device, used to detect the temperature near the first heating element 30, and the second temperature detection device 104 can be understood as an upper temperature detection device, used to detect the temperature near the second heating element 40. The first temperature detection device 103 may be disposed below the bottom wall of the frying drum 20 to detect the temperature of that bottom wall; the second temperature detection device 104 may be disposed in the outer shell assembly 10 and above the heating cavity 101 to detect the temperature above the heating cavity 101.

[0040] The first measurement temperature can be determined by the temperature measured by the lower detection device, the temperature measured by the upper detection device, or the combined value of the temperatures measured by the upper and lower detection devices. Optionally, the combined value of the temperatures measured by the upper and lower detection devices can be the minimum, maximum, average, or square root of the temperatures measured by the upper and lower detection devices. The first measurement temperature can be understood as the operating temperature of 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 the 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 the temperature to the control component 50.

[0043] The control component 50 can obtain a first measured temperature based on the temperature reported by the first temperature detection device 103 and the temperature reported by the second temperature detection device 104, and adjust the heating parameters of the first heating element 30 and the second heating element 40 based on the first measured temperature, thereby achieving precise temperature control of the heating cavity 101 and improving the temperature uniformity in the heating cavity 101.

[0044] In some embodiments, considering that the temperature resistance of the thermocouple detection circuit is higher than that of the NTC detection circuit, the fan 102 can accelerate the heat dissipation of the second heating element 40. In this embodiment, 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 embodiments, the control component 50 can execute the cooking process after receiving a cooking command. In response to the cooking appliance 100 being in cooking mode, the control component 50 can determine cooking parameters and, while the cooking appliance 100 is in cooking mode, detect a first measured temperature in the heating cavity 101 through the temperature detection device 60. If the first measured temperature is not greater than a first preset temperature, the control component 50 can control the first heating element 30 to heat at a first preset power. If the first measured temperature is greater than the first preset temperature, or if the first heating element 30 heats at the first preset power for a target duration, the control component 30 can control the first heating element 30 to heat at a second preset power less than the first preset power. This allows the cooking appliance 100 to flexibly adjust the heating power of the heating element according to the temperature in the heating cavity 101 during stewing, thereby shortening the heating time of stewing, improving the uniformity of temperature in the heating cavity during stewing, and enhancing the stewing performance of the cooking appliance 100.

[0046] Please see Figure 2 , Figure 2 A schematic flowchart illustrating a control method for a cooking appliance according to an embodiment of this application is shown. In a specific embodiment, this cooking method can be applied to, for example... Figure 3 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 4 The cooking appliance may include a heating chamber, a first heating element disposed at the bottom of the heating chamber, a second heating element disposed at the top of the heating chamber, 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 use a cooking appliance as an example to illustrate this. 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 being in cooking mode, determine cooking parameters.

[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 appliances to cook food can include stewing, air frying, grilling, baking, etc. Cooking parameters can include cooking time, cooking stages, cooking methods, and types of ingredients being cooked.

[0050] As one feasible approach, the cooking appliance can receive a first stewing instruction input by the user. This first stewing instruction may include a cooking time and the type of food in the heating chamber. Accordingly, upon receiving the first stewing instruction, the cooking appliance can determine that it needs to enter a stewing cooking mode. Furthermore, the cooking appliance can parse the first stewing instruction to obtain the cooking time and the type of food in the heating chamber, and control the heating parameters of the heating elements within the cooking appliance during the cooking time, or control the heating parameters of the heating elements within the cooking appliance in conjunction with the type of food in the heating chamber during the cooking time, to stew the food.

[0051] As another feasible approach, the cooking time for air frying in stewing is fixed. The cooking appliance can receive a second stewing command input by the user, wherein the second stewing command does not include a cooking time. Accordingly, upon receiving the second stewing command, the cooking appliance can determine that it needs to be controlled to enter stewing mode. Within this fixed cooking time, the cooking appliance can control the heating parameters of its heating element to stew the food.

[0052] In some implementations, the cooking appliance can determine the cooking time in response to the appliance being in cooking mode. Optionally, the cooking time can be set by the user or obtained from third-party experimental data, such as 30 minutes, 40 minutes, 50 minutes, etc., without limitation. Optionally, the cooking appliance can determine the cooking time and obtain the type of food in the heating chamber in response to the appliance being in cooking mode; wherein, the type of food in the heating chamber can be set by the user or obtained from third-party experimental data, such as the user setting it to a type of food like broth or clear broth.

[0053] For example, the cooking appliance includes cooking modes, keep-warm modes, and cleaning modes. The cooking modes may include stewing, air-frying, and grilling menus. The stewing menu can be used to stew foods such as porridge and soup. The stewing menu can have multiple cooking times, each corresponding to a different food type. Users can press the button corresponding to a cooking mode and select the desired cooking time from the various cooking times available in the stewing menu. Users can also select the type of food in the heating chamber from the various food types available in the stewing menu. After selecting the cooking time, users can press the button corresponding to that cooking mode again to activate the stewing mode. The cooking appliance can also enter the cooking mode upon receiving the user-set cooking time and / or the type of food in the heating chamber, and adjust the heating parameters of the heating element within that cooking time to stew the food.

[0054] The cooking appliance may include indicator lights corresponding to stewing or simmering menu functions. These indicator lights can be illuminated after the cooking appliance enters the cooking mode. Optionally, the cooking appliance may also display the time it entered the cooking mode on its screen, and may also display a stewing countdown on the screen based on the cooking duration and the duration the appliance has been in the cooking mode.

[0055] In some embodiments, cooking parameters may include cooking stages; wherein the cooking appliance used for stewing or simmering may include one or more cooking stages, and different cooking stages correspond to different preset temperatures; wherein the different preset temperatures may be set by the user or obtained through third-party experimental data; wherein the heating parameters of the heating element of the cooking appliance corresponding to different cooking stages may be different or the same, and are not limited herein. The cooking appliance may determine the cooking stage based on the relationship between the first measured temperature and the preset temperature.

[0056] For example, the cooking stages of a cooking appliance for stewing may include a high-power initial charging stage, a slow simmering stage to enhance aroma, and a heat reduction and overflow prevention stage. Accordingly, the cooking appliance can stew for the specified cooking time and return to standby mode after the cooking time is reached. Each cooking stage may correspond to multiple preset temperatures, including a first preset temperature, a second preset temperature, and a third preset temperature. The first preset temperature corresponds to the high-power initial charging stage of the cooking appliance for stewing, the second preset temperature corresponds to the slow simmering stage, and the third preset temperature corresponds to the heat reduction and overflow prevention stage. The first preset temperature can be in the range of 70℃ to 90℃, the second preset temperature can be in the range of 95℃ to 105℃, and the third preset temperature can be in the range of 90℃ to 97℃.

[0057] Step S120: During the cooking process, the first measured temperature inside the heating chamber is detected by the temperature detection device.

[0058] In some embodiments, the cooking appliance can detect a first measured temperature within the heating cavity via a temperature detection device while the appliance is in cooking mode. This first measured temperature can be understood as the operating temperature within the heating cavity. During the cooking time, the cooking appliance can detect the temperature near the first heating element via the first temperature detection device and use that temperature as the first measured temperature within the heating cavity; alternatively, the cooking appliance can detect the temperature near the second heating element via a second temperature detection device and use that temperature as the first measured temperature within the heating cavity.

[0059] In this case, the average, median, or arithmetic mean of the temperature measured by the first temperature detection device and the temperature measured by the second temperature detection device can also be used as the first measured temperature inside the heating cavity.

[0060] In some embodiments, the cooking appliance may display a first measured temperature within the heating cavity of the cooking appliance on a screen included in the cooking appliance. Specifically, the cooking appliance may acquire the first measured temperature within the heating cavity in real time during cooking mode and display this first measured temperature on the screen included in the cooking appliance to improve the user experience.

[0061] In some embodiments, when the cooking appliance includes a fan, the cooking appliance can control the fan to operate at a fourth fan speed during the cooking process to introduce fresh air into the heating chamber, increase the oxygen content in the heating chamber, improve the taste of the food in the heating chamber, and accelerate heat dissipation after cooking, shortening the cooling time of the food. The fourth fan speed can be a high, medium, or low speed setting of the fan, and is not limited thereto.

[0062] Step S130: In response to the first measured temperature not being greater than the first preset temperature, control the first heating element to heat at the first preset power.

[0063] In some embodiments, after the cooking appliance determines the operating temperature within the heating chamber, it can control the heating parameters of the first and second heating elements based on the relationship between the operating temperature and multiple preset temperatures. These multiple preset temperatures can correspond to different cooking stages when the cooking appliance is used for stewing or simmering.

[0064] 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 power of the first heating element; wherein heating the first heating element at maximum power can be understood as heating the first heating element at full power.

[0065] 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 third preset power, wherein the third preset power may include a power lower than the maximum power of the second heating element.

[0066] 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.

[0067] Where the first measured temperature is determined as the operating temperature within the heating chamber, the cooking appliance can control the heating parameters of the first and second heating elements based on the relationship between the first measured temperature and multiple preset temperatures. The multiple preset temperatures may include a first preset temperature, a second preset temperature, and a third preset temperature. The first preset temperature can be preset within the cooking appliance or obtained by the cooking appliance from a connected cloud or electronic device. This first preset temperature may correspond to the high-power initial surge phase of stewing or cooking, can be obtained through third-party experimental data, and can be set within the range of 70°C to 90°C.

[0068] In some embodiments, the cooking appliance can acquire a first measured temperature in real time, compare the first measured temperature with a first preset temperature, 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 in the cooking appliance according to the first magnitude relationship.

[0069] In one feasible manner, the cooking appliance can control the second heating element to stop heating and control the first heating element to heat at a first preset power in response to a first measured temperature not exceeding a first preset temperature.

[0070] The first preset temperature can be the maximum heating power of the first heating element, or it can be less than the maximum heating power of the first heating element, and is not limited here.

[0071] The first heating element can be an electromagnetic heating element. Considering that the electromagnetic heating element can achieve rapid and intense cooking over a large area, in this embodiment, the cooking appliance can control the second heating element to stop heating in response to the first measured temperature not being greater than the first preset temperature, and control the first heating element to heat at the first preset power. The first preset power can be understood as the maximum heating power of the first heating element, and the first heating element heating at the first preset power can also be understood as the first heating element heating at full power.

[0072] As an implementable approach, when the cooking appliance includes a fan, the cooking appliance can control the second heating element to stop heating while controlling the first heating element to heat at a first preset power in response to the first measured temperature not exceeding a first preset temperature, and can also control the fan to stop rotating. Thus, the cooking appliance can achieve rapid and intense cooking over a large area through the first heating element located at the bottom of the heating chamber, allowing the heat of the ingredients and water to be evenly distributed and quickly approaching a boiling state, while also saving cooking time for stewing and simmering cooking appliances.

[0073] Step S140: If the first measured temperature is greater than the first preset temperature, or the first heating element heats the target duration at the first preset power, then control the first heating element to heat at the second preset power, wherein the second preset power is less than the first preset power.

[0074] As one feasible approach, after the cooking appliance controls the first heating element to continuously heat at a first preset power, if it detects that the first measured temperature is greater than the first preset temperature, or detects that the first heating element has reached the target duration at the first preset power, it can then control the first heating element to heat at a second preset power. The second preset power can be less than the first preset power, based on the heating element heating the heating chamber with a low flame, so that the heat and temperature within the heating chamber are more uniform and remain balanced at the boiling critical state for a longer period. For example, the second preset power can be in the range of 20% to 50% of the first preset power.

[0075] As another feasible approach, after the cooking appliance controls the first heating element to continuously heat at a first preset power, if it detects that the first measured temperature is greater than the first preset temperature, or if it detects that the first heating element has reached the target duration at the first preset power, it can control the first heating element to heat at a second preset power, and can also control the second heating element to heat at a third preset power. The third preset power can be determined based on the type of food in the heating chamber, and can also be less than the maximum heating power corresponding to the second heating element.

[0076] In some embodiments, the cooking appliance may be pre-set with heating powers corresponding to different ingredients for stewing. The cooking appliance can determine the type of ingredient in the heating chamber while simultaneously determining the cooking time; correspondingly, the cooking appliance can determine the heating power corresponding to that ingredient type as a third preset power. Accordingly, the third preset power can be determined based on the type of ingredient in the heating chamber and may be less than the maximum heating power corresponding to the second heating element, for example, the second preset power may be in the range of 0% to 80% of the maximum heating power corresponding to the second heating element. For example, if the type of ingredient in the heating chamber is stock, the third preset power is determined based on this stock type as 75% of the maximum heating power corresponding to the second heating element; if the type of ingredient in the heating chamber is clear broth, the third preset power is determined based on this clear broth type and is less than the third preset power corresponding to stock type, being 50% of the maximum heating power corresponding to the second heating element.

[0077] The target duration can be preset in the cooking appliance. This target duration can be set by the user or determined based on the type of food in the heating chamber. For example, the target duration is determined based on the type of food in the heating chamber. Specifically, the target duration is 30 minutes for broth and 20 minutes for clear broth. The target duration for clear broth is shorter than that for broth to improve the cooking appliance's performance in broth stewing. When the first heating element reaches the target duration at a first preset power, it signifies that the cooking appliance has reached the target duration during its initial high-power surge. Therefore, the heating element's operating time can be used as a condition for switching the cooking appliance's heating program.

[0078] It can be understood that when the cooking appliance detects that the first measured temperature is greater than the first preset temperature, or that the first heating element has been heated to the target time at the first preset power, it controls the first heating element to heat at a second preset power lower than the first preset power. This allows the heating element to heat over a large area with a low flame, achieving slow simmering and keeping the food in the heating chamber in a state of gentle boiling. At the same time, the cooking appliance can control the second heating element to heat at a third preset power. This allows the heating element to heat over a large area with a low flame, achieving slow simmering and keeping the food in the heating chamber in a state of gentle boiling. It also makes the boiling of the food and water more uniform, resulting in a richer and more fragrant dish, thus improving the cooking performance of the cooking appliance.

[0079] As an implementable approach, when the cooking appliance includes a fan, the appliance can control the fan to operate at a first wind speed in response to a first measured temperature exceeding a first preset temperature, or the first heating element heating at a first preset power for a target duration. This fan rotation ensures that the heat and temperature within the heating chamber are maintained at the boiling critical state for a longer and more even time. The first wind speed can be low, medium, high, etc. For example, after controlling the second heating element to stop heating, controlling the first heating element to heat at the first preset power, and controlling the fan to stop rotating, if the cooking appliance detects that the first measured temperature exceeds the first preset temperature, or the first heating element heating at the first preset power for the target duration, it can control the first heating element to heat at a second preset power, and can also control the second heating element to heat at a third preset power, and can control the fan to rotate at medium speed. This allows for a more even boiling state and cooking of the ingredients and water, resulting in a richer flavor, while maintaining a gentle boil based on the heating element's use of low heat over a large area.

[0080] In some embodiments, after the cooking appliance controls the first heating element to heat at a second preset power and / or the second heating element to heat at a third preset power, if it is detected that the first measured temperature is not less than the second preset temperature for a continuous first duration, the first heating element and / or the second heating element can be controlled to stop heating.

[0081] As an implementable approach, when the cooking appliance includes a fan, the appliance can control the fan to operate at a second wind speed in response to a first measured temperature not being lower than a second preset temperature for a continuous first duration. This prevents the large-area heating of the heating element from causing the bubbles generated by boiling food in the heating chamber to overflow. By utilizing the fan and the heating stop in conjunction with bubble breaking, the cooking performance is improved while saving energy and enhancing the user experience. The second wind speed can be greater than the first wind speed. For example, after controlling the first heating element to heat at a second preset power, controlling the second heating element to heat at a third preset power, and controlling the fan to operate at the first wind speed, if the cooking appliance detects that the first measured temperature is not lower than the second preset temperature for a continuous first duration, it can control both the first and second heating elements to stop heating and control the fan to operate at the second wind speed. This prevents the large-area heating of the heating element from causing the bubbles generated by boiling water in the heating chamber to overflow. By utilizing the fan and the heating stop in conjunction with bubble breaking, the heat in the heating chamber is rapidly circulated and reduced, and the strong wind breaks the boiling bubbles, preventing heat overflow and improving the cooking performance and user experience. The second wind speed can be the high-speed setting of full-speed rotation.

[0082] In some embodiments, after the cooking appliance controls the first heating element and / or the second heating element to stop heating, if the first measured temperature is detected to be lower than a third preset temperature, the first heating element can be controlled to heat at a fourth preset power, and / or the second heating element can be controlled to heat at a fifth preset power. The fourth preset power is lower than the first preset power, and the fifth preset power can be determined based on the type of food in the heating chamber, or it can be lower than the maximum heating power corresponding to the second heating element.

[0083] As one feasible approach, when the cooking appliance includes a fan, the cooking appliance can control the fan to operate at a third fan speed in response to a first measured temperature being lower than a third preset temperature; wherein the third fan speed may be greater than the first fan speed.

[0084] The cooking appliance controls the first heating element to heat at a fourth preset power, and / or the second heating element to heat at a fifth preset power. This can be understood as the cooking appliance controlling the first heating element to heat at a second preset power, and / or the second heating element to heat at a third preset power. In other words, the cooking appliance returns to the slow cooking stage, thereby improving the stewing performance and enhancing the user experience.

[0085] In some embodiments, during the operation of the cooking appliance, a temperature detection device included in the cooking appliance can collect a first measured temperature within the heating cavity in real time. If the first measured temperature is detected to be higher than a 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. The first over-temperature protection temperature can be set by the user or obtained from third-party experimental data, and is not limited here. For example, the first over-temperature protection temperature may be 130℃, 140℃, 150℃, etc.

[0086] In some embodiments, the cooking appliance may have a pre-set overheat protection temperature for a first temperature detection device, wherein the cooking appliance can obtain this overheat protection temperature as a second overheat protection temperature; the cooking appliance may also have a pre-set overheat protection temperature for a second temperature detection device, wherein the cooking appliance can obtain this overheat protection temperature as a third overheat protection temperature. The cooking appliance can obtain the second overheat protection temperature corresponding to the first temperature detection device through third-party experimental data, or it can obtain the third overheat protection temperature corresponding to the second temperature detection device through third-party experimental data.

[0087] Optionally, the cooking appliance can determine the first over-temperature protection temperature as the over-temperature protection temperature preset by the first temperature detection device, or it can determine the first over-temperature protection temperature as the over-temperature protection temperature preset by the second temperature detection device. The cooking appliance can also determine the first over-temperature protection temperature as the minimum, maximum, or average value of the second and third over-temperature protection temperatures.

[0088] The cooking appliance includes a temperature detection device that may include a first temperature detection device for detecting the temperature near a first heating element, and a second temperature detection device for detecting the temperature near a second heating element. Accordingly, if the cooking appliance detects that the temperature detected by the first temperature detection device is higher than a second over-temperature protection temperature, it can control all heating loads included in the cooking appliance to stop heating and issue an alarm; or, if the cooking appliance detects that the temperature detected by the second temperature detection device is higher than a third over-temperature protection temperature, it can control all heating loads included in the cooking appliance to stop heating and issue an alarm. The second over-temperature protection temperature can be set above 150°C, and the third over-temperature protection temperature can be set above 130°C.

[0089] In some embodiments, while the cooking appliance receives the temperature measured by the first temperature detection device in real time, it can compare the real-time temperature measured by the first temperature detection device with a second over-temperature protection temperature, and / or compare the real-time temperature measured by the first temperature detection device with a third over-temperature protection temperature. If the temperature measured by the first temperature detection device 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, if the temperature measured by the second temperature detection device is greater than the third 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.

[0090] 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.

[0091] In some implementations, after the cooking appliance controls all heating loads within the cooking appliance to stop operating, if it is determined that the temperatures measured by the first temperature detection device and the second temperature detection device are both below the operating temperature threshold, the cooking appliance can be controlled to return to step S110 to proceed with 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 cooking appliance from associated electronic devices or the cloud. For example, the operating temperature threshold can be below 105°C.

[0092] 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 150°C. Furthermore, the user can set a second over-temperature protection temperature of 150°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 130°C. Furthermore, the user can set a third over-temperature protection temperature of 130°C based on this over-temperature protection temperature. If the cooking appliance detects that the temperature measured by the first temperature detection device is greater than the second over-temperature protection temperature, or vice versa, 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 temperature measured by the first temperature detection device and the temperature measured by the second temperature detection device can be detected in real time. If it is determined that the temperature measured by the first temperature detection device and the temperature measured by the second temperature detection device are both less than 105°C, the cooking appliance can be controlled to continue cooking for the duration of cooking. Based on the relationship between the first measured temperature in the heating cavity and the target values ​​of multiple preset temperatures, the heating parameters of the first heating element and the second heating element are controlled. Thus, during the cooking process, the safety of cooking is ensured, and the heating elements of the cooking appliance are controlled to cooperate in heating, thereby improving the stewing performance of the cooking appliance.

[0093] In some implementations, considering the heat storage capacity of electromagnetic heating, when the first heating element and the second heating element are electromagnetic heating elements, the cooking appliance can control the first heating element and the second heating element to stop power supply before the fan, so that the heating element stops working first at the end of cooking, and then the fan uses the residual heat to heat, which can improve the energy-saving performance of the cooking appliance and reduce the cooling time of the food.

[0094] It is understandable that during the stewing and cooking process, the cooking appliance uses the first and second heating elements to generate heat over a large area, shortening the heating time. The control fan and temperature detection device work together to precisely control the temperature inside the heating chamber of the cooking appliance, preventing heat from overflowing. This ensures that the stewing heat in the heating chamber is even, improving the overall temperature uniformity of the appliance, enhancing the performance of the stewing menu, and improving the user experience.

[0095] An embodiment of this application provides a control method for a cooking appliance. A first heating element is disposed at the bottom of the heating cavity, and a second heating element is disposed at the top of the heating cavity. A temperature detection device acquires a first measured temperature inside the heating cavity in real time. In response to the air fryer being in cooking mode, cooking parameters are determined. During the cooking process, based on the relationship between the first measured temperature of the cooking appliance and the first preset temperature for stewing, the heating elements of the cooking appliance are controlled to heat with different heating parameters. Thus, the cooking appliance can flexibly adjust the heating power of the heating elements according to the temperature inside the heating cavity during stewing, shortening the heating time of stewing, improving the temperature uniformity inside the heating cavity during stewing, and enhancing the stewing performance of the cooking appliance.
