[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, air fryers are becoming increasingly intelligent. Most air fryers use heating elements for cooking, but due to the high power of these elements, or the intermittent use of high-power heating, uneven heating can easily occur. Furthermore, during the cooking process, the high-speed rotation of the fan in the air fryer quickly removes moisture from the food, resulting in overly dry food. This leads to poor performance in baking-related cooking functions of air fryers. Therefore, air fryers suffer from poor baking performance in this technology.

[0020] To address the aforementioned problems, the inventors, through extensive research, discovered and proposed a control method, device, and air fryer as provided in this application. By placing a first heating element at the top of the heating chamber, and using a temperature detection device to obtain the working temperature within the heating chamber in real time, the cooking time and set temperature are determined during the air fryer's cooking mode. Within this cooking time, based on the relationship between the air fryer's working temperature and the target set temperature for baking, the heating elements of the air fryer are controlled to heat with different heating parameters. This allows for precise temperature control and moisture retention during baking, improving the air fryer's baking performance and enhancing the 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 an air fryer according to an embodiment of this application. In this embodiment, the air fryer 100 may include an outer shell assembly 10, a frying drum 20, a first heating element 30 (or a first heating element 30 and 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 at the top of the heating cavity 101; a second heating element 40 is disposed in the outer shell assembly 10 and located below the bottom wall. A control assembly 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 mode of the air fryer 100.

[0023] The air fryer 100 can have functions such as baking and heat preservation. The air fryer 100 generates hot air through a first heating element 30 and a 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 air fryer 100 can be an air fryer with a baking function.

[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 temperature 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 can be used to realize the baking function of the air fryer 100. Optionally, the first heating element 30 can be disposed at the top of the heating cavity 101 and may include an IH heating element, etc.; the second heating element 40 can be disposed at the bottom 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 bucket 20 is mainly located at the bottom of the fryer bucket 20, while the first heating element 30 is located at the top of the heating chamber and is far away from the food in the fryer bucket 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 ensuring that the air fryer 100 heats the food and improving the cooking reliability.

[0029] For example, considering that the food in the frying bucket 20 is mainly located at the bottom of the frying bucket 20, and that the heating element has the characteristics of generating heat over a large area and generating heat at a fast rate, in order to improve the baking effect of the air fryer 100, in this embodiment, the air fryer 100 can use the first heating element 30 located at the top of the heating chamber 101 to bake the food, thereby controlling the air fryer 100 to perform precise heating power control on the first heating element 30, improving the baking performance of the air fryer 100 and enhancing the user experience.

[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 drum 20, and is used to heat the air fryer 100 when it is in cooking mode, thereby raising the temperature of the gas in the heating chamber 101. 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 air fryer 100 when it is in cooking mode, thereby raising the temperature of the gas in the heating chamber 101. 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] The first heating element 30 and the second heating element 40 can be electromagnetic heating elements. Accordingly, it can be understood that the first heating element 30 and the second heating element 40 can heat out a large area of ​​heat, shorten the heating and baking time of the air fryer 100, improve the cooking performance of the air fryer 100, and improve the user experience.

[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 during the cooking mode of the air fryer 100.

[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 air fryer 100, so as to achieve precise temperature control of the air fryer 100 and improve the temperature uniformity in the heating chamber 101.

[0034] In some embodiments, the control component 50 is also connected to the 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 air fryer 100 based on this electrical signal. Optionally, the control component 50 may include a microcontroller unit (MCU).

[0035] Please refer to it again. Figure 1 In some embodiments, the air fryer 100 may further include a fan 102 for circulating hot air within the heating chamber 101. The fan 102 is disposed within the outer casing assembly 10 and located on the side of the outer casing assembly 10 closer to the heating chamber 101 than the first heating element 30, and is used to blow air into the heating chamber 101 during the cooking mode of the air fryer 100. The fan 102 is spaced apart from the first heating element 30 and is also fixedly disposed within the outer casing 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 first heating element 30 to circulate convection within the heating chamber 101, thereby heating the food. It should be noted that the fixing structure for fixing the first heating element 30 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 air fryer 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 first heating element 30, the fan 102 can accelerate the heat dissipation of the first heating element 30 and also accelerate the air flow in the heating chamber 101, thereby improving the temperature uniformity in the heating chamber 101 and improving the baking performance of the air fryer. In addition, during the process of the air fryer 100 controlling the heating element to heat and bake food, the adjustable fan 102 works in conjunction with the heating element to ensure that the heat in the heating chamber is even during the baking process of the air fryer 100, which can properly maintain the moisture of the food, improve the cooking performance of the air fryer 100, and enhance the user experience.

[0039] In some embodiments, the air fryer 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 air fryer 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 air fryer 100 and improving the baking performance of the air fryer 100.

[0040] Please refer to it again. Figure 1 In some embodiments, the temperature detection device 60 may include a first temperature detection device 103 (or 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 serve as the operating temperature of the heating chamber 101. The first temperature detection device 103 can be disposed within the outer casing assembly 10 and located above the heating chamber 101, for detecting the temperature above the heating chamber 101; the second temperature detection device 104 can be disposed below the bottom wall of the frying drum 20, for detecting the temperature of the bottom wall 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] In the case where the air fryer 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 of the top of the heating cavity 101, and report the 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 of the bottom of the heating cavity 101, and report the temperature as a second measured temperature to the control component 50.

[0043] The control component 50 can adjust the heating parameters of the first heating element 30 and the second heating element 40 based on the first and second measured temperatures, thereby achieving precise temperature control of the heating chamber 101, improving the temperature uniformity in the heating chamber 101, and improving the accuracy of the baking temperature control of the air fryer 100.

[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 control component 50 can determine the cooking time and set the temperature in response to the air fryer 100 entering the cooking mode. The set temperature corresponds to the temperature at which the air fryer 100 is used for baking. During the cooking time, the working temperature inside the heating chamber 101 is detected by the temperature detection device 60. Based on the target relationship between the working temperature and the set temperature, the first heating element 30 is controlled to heat based on the target power. The target power is positively correlated with the difference between the working temperature and the set temperature. This allows the air fryer 100 to accurately control the baking temperature and retain moisture during the baking process, improving the cooking performance of the air fryer 100 and enhancing the user experience.

[0046] Please see Figure 2 , Figure 2 A flowchart illustrating a control method for an air fryer according to an embodiment of this application is shown. This method involves placing a first heating element at the top of the heating chamber, acquiring the working temperature within the heating chamber in real time via a temperature detection device, and determining the cooking time and set temperature during the air fryer's cooking mode. Within this cooking time, based on the relationship between the air fryer's working temperature and the target set temperature for baking / cooking, the heating element of the air fryer is controlled to heat with different heating parameters. This allows for precise temperature control and moisture retention during baking, improving the air fryer's cooking performance and enhancing the user experience. In specific embodiments, this cooking method can be applied to, for example... Figure 5 The air fryer control device 200 and the air fryer 100 equipped with the air fryer control device 200 are shown. Figure 6 The following will use an air fryer as an example to discuss... Figure 2 The process is described in detail below. The air fryer includes a heating chamber, a first heating element, and a temperature detection device. The first heating element is located at the top of the heating chamber, and the temperature detection device is used to detect the working temperature inside the heating chamber. The control method of the air fryer may specifically include the following steps:

[0047] Step S110: In response to the air fryer entering the cooking mode, determine the cooking time and set the temperature, wherein the set temperature corresponds to the temperature of the air fryer when it is used for baking and cooking.

[0048] In some implementations, the air fryer may include operating modes such as a cleaning mode, a cooking mode, a keep-warm mode, and a standby mode. In cooking mode, the air fryer can cook the food placed inside. In standby mode, the components of the air fryer are in a standby state, and the air fryer can receive control commands input by the user and switch operating modes based on these commands. For example, in standby mode, the air fryer 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 of an air fryer can include baking, air frying, frying, stewing, etc.

[0050] As one feasible approach, the air fryer can receive a first baking instruction input by the user, which may include a cooking time. Accordingly, upon receiving the first baking instruction, the air fryer can determine that it needs to enter cooking mode. Furthermore, the air fryer can parse the first baking instruction to obtain the cooking time it carries, and within that cooking time, control the heating parameters of the heating elements included in the air fryer to bake the food.

[0051] As another feasible approach, the air fryer can be used for baking with a fixed cooking time. The air fryer can receive a second baking command input by the user, which does not specify a cooking time. Upon receiving this second baking command, the air fryer can determine whether to enter cooking mode and control the heating parameters of its heating elements within the fixed cooking time to bake the food.

[0052] The air fryer can determine the cooking time in response to the air fryer 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 air fryer can receive a third baking instruction input by the user, which may include a set temperature. Accordingly, upon receiving the third baking instruction, the air fryer can determine that it needs to enter cooking mode. Furthermore, the air fryer can parse the third baking instruction to obtain the set temperature, and control the heating parameters of the heating elements included in the air fryer according to the set temperature to bake the food.

[0054] As another feasible approach, the air fryer maintains a constant temperature during baking and cooking. The air fryer can receive a fourth baking command input by the user, which may not include a set temperature. Accordingly, upon receiving this fourth baking command, the air fryer can determine that it needs to enter cooking mode, set the constant temperature for baking and cooking as the set temperature, and control the heating parameters of the heating elements within the air fryer according to this set temperature to bake the food.

[0055] The set temperature can correspond to the temperature when the air fryer is used for baking and cooking, such as 100℃, 150℃, 200℃, etc., and is not limited here.

[0056] For example, an air fryer may include cooking modes, keep-warm modes, and cleaning modes. The cooking modes may include baking menus, air-frying menus, and stewing menus. The baking menus can be used to bake foods such as bread, cakes, and cookies. Users can press the button corresponding to a cooking mode on the air fryer and select the baking menu function from that mode. Similarly, users can input a cooking time and a set temperature, and then press the button corresponding to that cooking mode again to start the air fryer. The air fryer can also enter the cooking mode after receiving the user-set cooking time and temperature, and within that cooking time, adjust the first heating element of the air fryer to heat based on a target power according to the input set temperature to bake the food.

[0057] The air fryer may include indicator lights for baking menu functions, which can be illuminated when the air fryer enters the cooking mode. Optionally, the air fryer may also display the time it takes for the air fryer to enter the cooking mode on its screen, and may also display a baking countdown on the screen 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 air fryer can detect the operating temperature inside the heating chamber within that cooking time using a temperature detection device. Specifically, within the cooking time, the air fryer 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 chamber. Optionally, if the air fryer includes a second temperature detection device, the air fryer can also detect a second measured temperature near the second heating element using the second temperature detection device, and this second measured temperature can be used as the operating temperature inside the heating chamber.

[0060] The air fryer can 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 chamber.

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

[0062] Step S130: Based on the target magnitude relationship between the working temperature and the set temperature, control the first heating element to heat based on the target power, wherein the target power is positively correlated with the difference between the working temperature and the set temperature.

[0063] In some implementations, after the air fryer determines the input set temperature and the operating temperature inside the heating chamber, it can compare the operating temperature with the set temperature to obtain a target relationship between the two temperatures. Based on this target relationship, the first heating element can be controlled to heat based on a target power. This target power can be positively correlated with the difference between the operating temperature and the set temperature.

[0064] The target power may include the maximum heating power of the first heating element; heating with the first heating element at its maximum heating power can be understood as heating at full power. Optionally, the target power may also be positively correlated with the difference between the operating temperature and the set temperature within the range of 20% to 60% of the maximum heating power of the first heating element; the relationship between the target power and the difference between the operating temperature and the set temperature may include, but is not limited to, a positively correlated linear relationship, a positively correlated functional relationship, etc., and is not limited here.

[0065] In some implementations, when the air fryer includes a fan, the fan can be controlled to rotate during the cooking mode to circulate hot air and increase the rate of heat flow. For example, during the cooking mode, the air fryer can control the fan to rotate at a low, medium, or high speed to circulate hot air, allowing heat from the heating chamber to quickly flow to every part of the frying bowl, thus improving the uniformity of temperature within the heating chamber.

[0066] For example, the air fryer baking and cooking process may include an initial high-power preheating stage and a baking and puffing maintenance stage; correspondingly, the air fryer can perform baking and cooking within the cooking time and return to standby mode after the baking and cooking time is reached. The air fryer can determine the set temperature for baking and cooking during the baking and cooking process.

[0067] The air fryer can determine the first measured temperature as the working temperature inside the heating chamber. Accordingly, the air fryer can control the first heating element to heat at a target power based on the target relationship between the first measured temperature and the set temperature. For example, in response to the first measured temperature not exceeding a first preset temperature, the air fryer can control the first heating element to heat at a first preset power and control the fan to operate at a first wind speed to utilize the heating element for large-area heating, achieving rapid heating for baking and cooking. This allows the food inside the heating chamber to quickly approach the set temperature for balanced baking, thereby achieving precise control of the air fryer's baking balance and improving the user experience.

[0068] The first preset temperature can be calculated from the set temperature and the first adjusted temperature. The difference between the set temperature and the first adjusted temperature can be defined as the first preset temperature. The first adjusted temperature can be above 10°C, and correspondingly, the first preset temperature can be below 10°C below the set temperature. The first fan speed can be the medium or high setting to ensure hot air circulation and rapid heat distribution throughout the fryer. The first preset temperature can be understood as a transition temperature point, corresponding to the initial high-power preheating stage. A first measured temperature greater than the first preset temperature indicates that the temperature of the initial high-power preheating stage meets the transition temperature point, thus shifting the air fryer baking process from the initial high-power preheating stage to the baking and puffing stage.

[0069] Accordingly, if, after the air fryer controls the first heating element to heat at a first preset power, it detects that the first measured temperature is greater than the first preset temperature but less than the second preset temperature, or if the first heating element heats at the first preset power for a first target duration, it can control the first heating element to heat at the second preset power. This allows for the adjustment of the heating element's power to balance the heat generated, achieving precise temperature control and improving the air fryer's baking performance. The second preset temperature can be calculated from the set temperature and the second adjusted temperature. The difference between the set temperature and the second adjusted temperature can be defined as the second preset temperature. The first adjusted temperature can be within ±10°C, and correspondingly, the second preset temperature can be within ±10°C below the set temperature. The second preset temperature can be understood as a temperature equilibrium point, corresponding to the baking maintenance puffing stage. A first measured temperature less than the second preset temperature indicates that the temperature during the baking maintenance puffing stage meets the temperature equilibrium point. Therefore, the air fryer can maintain the baking process in the baking maintenance puffing stage and control the first heating element to turn on; otherwise, it can control the first heating element to turn off. The first target duration can be preset in the air fryer. This first target duration can be set by the user or obtained through third-party experimental data, and is not limited here. The first target duration can be used as a criterion for switching the air fryer's heating program from the initial high-power preheating stage to the baking and puffing stage.

[0070] The second preset power is positively correlated with the difference between the first measured temperature and the set temperature. For example, the second preset power can be within the range of 20% to 60% of the maximum heating power of the first heating element. Correspondingly, the value of the second preset power can be within this range and is positively correlated with the difference between the first measured temperature and the set temperature. The air fryer can control the fan to rotate at a second wind speed in response to the first measured temperature being greater than the first preset temperature. The second wind speed can be less than or equal to the first wind speed. For example, the second wind speed can be a medium or low setting to maintain a relative balance of heat and temperature within the heating chamber, allowing for appropriate moisture loss from the food and achieving a slow puffing effect during baking. This avoids the food becoming too dry or burnt, improving the baking performance of the air fryer.

[0071] Accordingly, if the air fryer detects that the first measured temperature is not less than the second preset temperature after controlling the first heating element to heat at the first preset power, or detects that the first heating element has reached the second target duration at the first preset power, it can control the first heating element to stop heating. This allows for precise temperature control by adjusting the power of the heating element to balance the large-area heat generated by the heating element, preventing the baked food from becoming too dry or burnt, thus improving the air fryer's baking performance and enhancing the user experience. The second target duration can be preset in the air fryer and can be longer than the first target duration. The second target duration can be understood as the basis for the air fryer's decision to stop heating the first heating element during the initial high-power preheating phase.

[0072] In some embodiments, the air fryer may further include a second heating element, which may be disposed at the bottom of the heating chamber of the air fryer; correspondingly, the temperature detection device in the air fryer may further include a second temperature detection device, which may be used to detect a second measuring temperature near the second heating element.

[0073] The air fryer can obtain a second relationship between a second measured temperature and a third preset temperature during the initial high-power preheating stage of baking and cooking, and control the working state of the second heating element based on this relationship. The third preset temperature can be understood as the control temperature of the second heating element. Accordingly, if the second measured temperature is detected to be lower than the third preset temperature, the second heating element can be controlled to heat at the third preset power; otherwise, the second heating element can be shut off to improve the rate of rapid heating during baking. The third preset temperature can be within a range of 30°C below the set temperature; the third preset power can be the maximum heating power of the second heating element.

[0074] The air fryer can obtain a third relationship between a second measured temperature and a fourth preset temperature during the baking and puffing stage of air fryer baking and cooking, and control the working state of the second heating element according to this third relationship. The fourth preset temperature can be understood as the temperature balance point for maintaining the second heating element's temperature. Accordingly, if the second measured temperature is detected to be lower than the fourth preset temperature, the second heating element can be controlled to heat at the fourth preset power; otherwise, the second heating element can be controlled to turn off, thereby improving the accuracy of baking temperature balance control. The fourth preset temperature can be within 30°C below the set temperature, and the fourth preset power can be within 20% to 50% of the maximum heating power of the second heating element.

[0075] An embodiment of this application provides a control method for an air fryer. By placing a first heating element at the top of the heating chamber and acquiring the working temperature inside the heating chamber in real time through a temperature detection device, the method determines the cooking time and set temperature during the air fryer's cooking mode. Within the cooking time, based on the relationship between the working temperature of the air fryer and the target set temperature for baking cooking, the method controls the heating element of the air fryer to heat with different heating parameters. This allows the air fryer to precisely control the baking temperature and moisture retention during baking, improving the cooking performance of the air fryer and enhancing the user experience.

[0076] Please see Figure 3 , Figure 3 A flowchart illustrating a control method for an air fryer according to an embodiment of this application is shown. This method is applied to the aforementioned air fryer, which includes a first temperature detection device for detecting a first measured temperature near a first heating element. The air fryer may also include a fan for providing circulating airflow to the heating chamber. The following will focus on... Figure 3 The process shown is described in detail. The control method of the air fryer may specifically include the following steps:

[0077] Step S210: In response to the air fryer entering the cooking mode, determine the cooking time and set the temperature, wherein the set temperature corresponds to the temperature of the air fryer when it is used for baking and cooking.

[0078] For a detailed description of step S210, please refer to the previous description of step S110, which will not be repeated here.

[0079] Step S220: During the cooking time, the working temperature inside the heating chamber is detected by the temperature detection device, wherein the working temperature includes a first measured temperature.

[0080] In some embodiments, the temperature detection device in the air fryer 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 air fryer 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 air fryer being in cooking mode, and can determine the first measured temperature as the operating temperature within the heating chamber.

[0081] Step S230: Obtain the first magnitude relationship between the first measured temperature and the first preset temperature, wherein the first preset temperature is calculated from the set temperature and the first adjusted temperature.

[0082] In some implementations, the air fryer can acquire a first measured temperature detected by a first temperature detection device in real time; accordingly, after acquiring the first measured temperature, the air fryer can compare the first measured temperature with a first preset temperature to obtain a first magnitude relationship between the first measured temperature and the first preset temperature.

[0083] The first preset temperature can be calculated from the set temperature and the first adjusted temperature. The difference between the set temperature and the first adjusted temperature can be defined as the first preset temperature. The first adjusted temperature can be above 10°C, and correspondingly, the first preset temperature can be below 10°C below the set temperature. The first adjusted temperature can be set by the user or obtained from third-party experimental data; no limitation is imposed here.

[0084] Step S240: Control the first heating element to heat based on the target power according to the first size relationship.

[0085] In some embodiments, after the air fryer obtains a first magnitude relationship between a first measured temperature and a first preset temperature, it can control the first heating element to heat based on a target power according to the first magnitude relationship. Specifically, the air fryer can respond to the first measured temperature not exceeding the first preset temperature by controlling the first heating element to heat at a first preset power, where the first preset power can be the maximum heating power of the first heating element, allowing the air fryer to perform high-power preheating to achieve rapid food heating.

[0086] In some embodiments, after the air fryer controls the first heating element to heat at a first preset power, if it detects that the first measured temperature is greater than the first preset temperature and less than the second preset temperature, or if it detects that the first heating element has heated at the first preset power for a first target duration, it can then control the first heating element to heat at the second preset power. The second preset temperature can be calculated from a set temperature and a second adjustable temperature; specifically, the difference between the set temperature and the second adjustable temperature can be determined as the second preset temperature.

[0087] The first adjustable temperature can be within ±10℃, and correspondingly, the second preset temperature can be within ±10℃ below the set temperature.

[0088] Optionally, in some embodiments, after the air fryer controls the first heating element to heat at a first preset power, if it detects that the first heating element has reached a first target duration by heating at the first preset power, it can control the first heating element to heat at a second preset power.

[0089] The second preset power is positively correlated with the difference between the first measured temperature and the set temperature. For example, the second preset power can be in the range of 20% to 60% of the maximum heating power of the first heating element and is positively correlated with the difference between the first measured temperature and the set temperature.

[0090] In some implementations, after the air fryer controls the first heating element to heat at a first preset power, if it detects that the first measured temperature is not lower than a second preset temperature, it can control the first heating element to stop heating to avoid the baked food becoming too dry or too burnt. The second target duration can be greater than the first target duration.

[0091] Optionally, after the air fryer controls the first heating element to heat at a first preset power, if it detects that the first heating element has reached a second target duration at the first preset power, it can control the first heating element to stop heating in order to avoid the baked food from becoming too dry or too burnt.

[0092] In some embodiments, the air fryer can control the fan to operate at a first wind speed during the cooking time; wherein the first wind speed can be a medium, high, or low speed setting of the fan. For example, the air fryer can control the fan to rotate at a medium or high speed in response to a first measured temperature not exceeding a first preset temperature to accelerate hot air circulation; the air fryer can also control the fan to rotate at a medium or low speed in response to a first measured temperature exceeding the first preset temperature to maintain a relative balance of heat and temperature within the heating chamber, allowing appropriate moisture loss from the food, achieving a slow puffing effect during baking, and preventing the baked food from becoming too dry or burnt.

[0093] 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 air fryer also includes a fan for providing circulating airflow to the heating chamber. This embodiment can also obtain a first magnitude relationship between the first measured temperature and a first preset temperature, wherein the first preset temperature is calculated from a set temperature and a first adjusted temperature. Based on the first magnitude relationship, the first heating element is controlled to heat based on a target power. Furthermore, during the cooking time, the heating parameters of the heating element in the air fryer are controlled according to the relationship between the first measured temperature and the first preset temperature to achieve precise temperature control and moisture retention in baking, thereby improving the baking performance of the air fryer and enhancing the user experience.

[0094] Please see Figure 4 , Figure 4A schematic flowchart of a control method for an air fryer according to an embodiment of this application is shown. This method is applied to the aforementioned air fryer, which may further include a second heating element disposed at the bottom of the heating chamber. The temperature detection device may also include a second temperature detection device for detecting a second measured temperature near the second heating element. The following will focus on... Figure 4 The process shown is described in detail. The control method of the air fryer may specifically include the following steps:

[0095] Step S310: In response to the air fryer entering the cooking mode, determine the cooking time and set the temperature, wherein the set temperature corresponds to the temperature of the air fryer when it is used for baking and cooking.

[0096] Step S320: During the cooking time, the working temperature inside the heating chamber is detected by the temperature detection device, wherein the working temperature includes a first measured temperature.

[0097] Step S330: Obtain the first magnitude relationship between the first measured temperature and the first preset temperature, wherein the first preset temperature is calculated from the set temperature and the first adjusted temperature.

[0098] Step S340: Control the first heating element to heat based on the target power according to the first size relationship.

[0099] For a detailed description of steps S310-S340, please refer to the previous description of steps S210-S240, which will not be repeated here.

[0100] Step S350: In response to the first measured temperature not being greater than the first preset temperature, obtain a second magnitude relationship between the second measured temperature and the third preset temperature, wherein the third preset temperature is calculated from the set temperature and the third adjusted temperature.

[0101] In some embodiments, when the air fryer includes a second heating element and a second temperature detection device, the air fryer can acquire a second measured temperature detected by the second temperature detection device in real time. Accordingly, after obtaining a first magnitude relationship between the first measured temperature and a first preset temperature, the air fryer can, in response to the first measured temperature not being greater than the first preset temperature, compare the second measured temperature with a third preset temperature to obtain a second magnitude relationship between the second measured temperature and the third preset temperature.

[0102] The third preset temperature can be calculated from the set temperature and the third adjustable temperature. Specifically, the difference between the set temperature and the third adjustable temperature can be defined as the third preset temperature. The third adjustable temperature can be above 30°C, and correspondingly, the third preset temperature can be below 30°C from the set temperature. The third adjustable temperature can be set by the user or obtained from third-party experimental data; no limitation is imposed here.

[0103] Step S360: Control the working state of the second heating element according to the second size relationship.

[0104] In some embodiments, after the air fryer obtains a second magnitude relationship between the second measured temperature and the third preset temperature, it can control the working state of the second heating element according to the second magnitude relationship.

[0105] As an feasible approach, if the air fryer detects that the second measured temperature is lower than the third preset temperature, it can control the second heating element to heat at the third preset power to control the second heating element to perform auxiliary heating, thereby improving the air fryer's rapid heating efficiency and improving the air fryer's baking performance.

[0106] The third preset power can be the maximum heating power of the second heating element, or it can be less than the maximum heating power of the second heating element, and is not limited here.

[0107] As another feasible approach, if the air fryer detects that the second measured temperature is not less than the third preset temperature, it can control the second heating element to stop heating, so as to avoid the food baked in the air fryer becoming too dry or too burnt, thereby improving the baking performance of the air fryer.

[0108] Step S370: In response to the first measured temperature being greater than the first preset temperature, or in response to the first heating element heating at the first preset power for the first target duration, obtain a third magnitude relationship between the second measured temperature and the fourth preset temperature, wherein the fourth preset temperature is calculated from the set temperature and the fourth adjusted temperature.

[0109] In some embodiments, the air fryer can, in response to a first measured temperature being greater than a first preset temperature, compare a second measured temperature with a fourth preset temperature to obtain a third relationship between the second measured temperature and the fourth preset temperature. The fourth preset temperature can be calculated from a set temperature and a fourth adjustable temperature. The difference between the set temperature and the fourth adjustable temperature can be determined as the fourth preset temperature, where the fourth adjustable temperature can be within 30°C, and correspondingly, the fourth preset temperature can be within 30°C below the set temperature.

[0110] Optionally, the air fryer may also respond to the first heating element heating at a first preset power for a first target duration to obtain a third magnitude relationship between a second measured temperature and a fourth preset temperature.

[0111] Step S380: Control the working state of the second heating element according to the third size relationship.

[0112] In some implementations, after the air fryer obtains a third relationship between the second measured temperature and the fourth preset temperature, it can control the working state of the second heating element according to the third relationship.

[0113] As an feasible approach, if the air fryer detects that the second measured temperature is lower than the fourth preset temperature, it can control the second heating element to heat at the fourth preset power to control the second heating element to perform auxiliary heating, thereby improving the accuracy of the air fryer baking temperature control and improving the air fryer baking performance.

[0114] The fourth preset power can be less than the third preset power. For example, the third preset power can be in the range of 20% to 60% of the maximum heating power of the second heating element in order to control the temperature of the air fryer to maintain balance.

[0115] As another feasible approach, if the air fryer detects that the second measured temperature is not less than the fourth preset temperature, it can control the second heating element to stop heating, so as to avoid the food baked in the air fryer becoming too dry or too burnt, thereby improving the baking performance of the air fryer.

[0116] In some embodiments, the air fryer may be pre-set with an ultra-high temperature protection temperature corresponding to a first temperature detection device, wherein the air fryer can obtain the ultra-high temperature protection temperature as a first over-temperature protection temperature; the air fryer may be pre-set with an ultra-high temperature protection temperature corresponding to a second temperature detection device, wherein the air fryer can obtain the ultra-high temperature protection temperature as a second over-temperature protection temperature.

[0117] 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 air fryer can obtain the first over-temperature protection temperature corresponding to the first temperature detection device through third-party experimental data, and can also obtain the second over-temperature protection temperature corresponding to the second temperature detection device through third-party experimental data.

[0118] The air fryer can simultaneously obtain a first measured temperature and a second measured temperature in real time, and 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 and second heating elements can be controlled to stop heating, and all heating loads included in the air fryer can be controlled to stop working, in order to protect the air fryer from over-temperature.

[0119] In some implementations, an alarm message can be generated after all heating loads included in the air fryer have stopped operating. The air fryer 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 air fryer or cutting off the power.

[0120] In some implementations, after the air fryer controls all heating loads to stop operating, if it is determined that both the first and second measured temperatures are below the operating temperature threshold, the air fryer can be controlled to return to step S310 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 air fryer or obtained by the air fryer from associated electronic devices or the cloud. For example, the operating temperature threshold can be below 105°C.

[0121] 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 air fryer 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 air fryer to stop working. Furthermore, after the air fryer controls all heating loads to stop working, it can monitor the first and second measured temperatures in real time. If it is determined that both the first and second measured temperatures are less than 105°C, it can control the air fryer to continue cooking for the specified time, controlling the heating parameters of the first and / or second heating elements according to the relationship between the working temperature inside the heating chamber and the target value of the input set temperature. This ensures the safety of cooking in the air fryer and improves its baking performance.

[0122] The cooking method provided in one embodiment of this application is different from... Figure 3 The cooking method shown in this embodiment can also be modified so that 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 are controlled to stop heating. During the cooking process of the air fryer, the safety of air fryer cooking is ensured. At the same time, according to the relationship between the working temperature in the heating cavity and the target value of the input set temperature, the heating elements included in the air fryer are controlled to cooperate in heating, thereby improving the baking performance of the air fryer.
