[0019] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0020] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0021] With the development of science and technology, cooking utensils are becoming more and more intelligent, and the heating chambers of cooking utensils are becoming more and more diversified. For example, an air fryer may include a square frying barrel, and for another example, an air fryer may include a cylindrical frying barrel, etc. In the related art, most cooking utensils use a single heating tube to cook food, and in the related art, the heating chambers of cooking utensils tend to develop in a diversified manner. Therefore, in the process of cooking food by the cooking utensils, the cooking performance of the cooking utensils is poor due to the uneven temperature of the heating chamber. For example, the square frying barrel included in the air fryer is prone to weak heat in the four corners, that is, it is easy to have uneven temperature of the whole machine and poor cooking effect of the menu of the cooking utensils.

[0022] Therefore, in the related art, there is a problem of low cooking performance when the cooking utensils are cooking food.

[0023] In view of the above problems, the inventor has discovered after long-term research and proposed a control method, device and cooking appliance provided in the embodiments of the present application. When the cooking appliance is in the cooking mode, the preset temperature and cooking time are determined, and the heating parameters of the three heat sources included in the cooking appliance are controlled according to the relationship between the working temperature of the cooking appliance and the preset temperature during the cooking time. The three heat sources are used to coordinate heating to improve the temperature uniformity of the heating cavity in the cooking appliance and enhance the cooking performance of the cooking appliance. The specific cooking method is described in detail in the subsequent embodiments.

[0024] See also Figure 1 , which shows a schematic diagram of the structure of a cooking device provided by an embodiment of the present application. In the embodiment of the present application, the cooking device 100 may include a housing assembly 10, a frying bucket 20, a first heating device 30, a second heating device 40, a third heating device 50 and a control assembly 60 (not shown).

[0025] The housing assembly 10 is provided with a receiving cavity, and the frying vat 20 is movably arranged in the receiving cavity. The frying vat 20 may include a bottom wall and a peripheral wall, wherein the peripheral wall is connected to the periphery of the bottom wall to form a heating cavity 101 for accommodating food. The first heating device 30 is arranged in the housing assembly 10 and is located above the heating cavity 101; the second heating device 40 is arranged in the housing assembly 10 and is surrounded by the peripheral wall; the third heating device 50 is arranged in the housing assembly 10 and is located below the bottom wall. The control component 60 is respectively connected to the first heating device 30, the second heating device 40 and the third heating device 50, and is used to control the heating parameters of the first heating device 30, the second heating device 40 and the third heating device 50, such as heating time, heating power, etc., when the cooking appliance 100 is in the cooking mode.

[0026] The cooking utensil 100 may have functions such as cooking and heat preservation. The cooking utensil 100 may generate hot air through the first heating device 30, the second heating device 40 and the third heating device 50, and then the hot air is quickly circulated in a sealed space through a hot air convection system, thereby realizing a method for heating food. In an embodiment of the present application, the cooking utensil 100 may be an air fryer with a cooking function.

[0027] Among them, according to Figure 1It can be seen that the housing assembly 10 plays a supporting role. The housing assembly 10 includes a bottom cover, a side wall and a top plate. The bottom cover and the top plate are spaced apart in a specified direction. The specified direction refers to a 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 housing assembly 10 is provided with a receiving cavity, and the receiving cavity is used to receive the frying vat 20. The side wall is formed with an opening for the frying vat 20 to be placed in the receiving cavity.

[0028] In some embodiments, a control panel is provided on the outer surface of the side wall of the housing assembly 10 or the surface of the top plate away from the bottom cover, and the control panel includes one or more functional controls, including but not limited to start controls, reservation controls, time setting controls, mode setting controls, food type setting controls, etc.

[0029] The frying vat 20 can be movably disposed in the accommodating cavity. When the frying vat 20 is disposed in the accommodating cavity, a handle is provided on the surface of the frying vat 20 exposed in the accommodating cavity for a user to grasp. The frying vat 20 includes a bottom wall and a peripheral wall, and the peripheral wall surrounds and is connected to the periphery of the bottom wall to form a heating cavity 101 for accommodating food.

[0030] The first heating device 30, the second heating device 40 and the third heating device 50 are used to realize the cooking function of the cooking device 100. Optionally, the first heating device 30 may include a heating tube, an infrared heating plate, etc., the second heating device 40 may include a heating belt, a heating tube, etc., wherein the heating belt may be arranged around the peripheral wall of the frying vat, and the third heating device 50 may include a heating tube, an infrared heating plate, etc., which are not limited here; wherein the first heating device 30, the second heating device 40 and the third heating device 50 may be the same heating device or different heating devices; wherein the maximum power of the first heating device 30, the second heating device 40 and the third heating device 50 may be the same or different.

[0031] For example, considering that the food in the frying vat 20 is mainly located at the bottom of the frying vat 20, and the first heating device 30 is located above the heating chamber and is far away from the food in the frying vat, in this embodiment, the maximum power of the first heating device 30 can be set to be greater than the maximum power of the third heating device 50, and the maximum power of the third heating device 50 is greater than the maximum power of the second heating device 40, thereby ensuring that the cooking device 100 heats the food and improves the cooking reliability. For example, the first heating device 30 includes a high-power heating tube, the second heating device 40 includes a low-power heating belt, and the third heating device 50 includes a medium-power infrared tube; the first heating device 30 may include a heating tube with parameters of DC voltage DC220V, 50Hz, and 1000W, the second heating device 40 may include a heating belt with parameters of DC220V, 50Hz, and 150W, and the third heating device 50 may include an infrared tube with parameters of DC220V, 50Hz, and 500W.

[0032] In some embodiments, the second heating device 40 may be disposed in the housing assembly 10 around the peripheral wall of the frying vat 20, or the second heating device 40 may be disposed at a single point on the peripheral wall of the frying vat 20. In this embodiment, in order to ensure the uniformity of the temperature in the heating chamber 101, the distance between the second heating device 40 and the third heating device 50 may be set to be greater than a distance threshold. The distance threshold may be set by the user or obtained through third-party experimental data. For example, the distance threshold is 2 cm.

[0033] In some embodiments, the first heating device 30 may be disposed in correspondence with the heating cavity 101 and fixedly disposed in the housing assembly 10 through a fixed structure, and is used for heating when the cooking utensil 100 is in a cooking mode, so that the temperature of the gas in the heating cavity 101 is increased. The second heating device 40 may be disposed in an annular manner in the housing assembly 10 corresponding to the peripheral wall of the frying vat 20, and is used for heating when the cooking utensil 100 is in a cooking mode, so that the temperature of the gas in the heating cavity 101 is increased. The third heating device 50 may be disposed in the housing assembly 10 corresponding to the bottom wall of the frying vat 20, and is used for heating when the cooking utensil 100 is in a cooking mode, so that the temperature of the gas in the heating cavity 101 is increased. It should be noted that the fixed structure for fixing the first heating device 30, the fixed structure for fixing the second heating device 40, and the fixed structure for fixing the third heating device 50 may be the same or different.

[0034] In some embodiments, considering that the range of heat radiation of the infrared disk is wider than the heating range of the heating tube, in this embodiment, the third heating device 50 may include an infrared heating disk, and then the bottom wall of the frying bucket 20 is heated based on the infrared disk with a larger heat dissipation range, thereby improving the efficiency of the cooking utensil 100 in heating the heating cavity 101 when cooking food, and also improving the uniformity of the temperature in the heating cavity 101.

[0035] In this embodiment, the control component 60 is connected to the first heating device 30, the second heating device 40 and the third heating device 50 respectively, and is used to control the heating parameters of the first heating device 30, the second heating device 40 and the third heating device 50 when the cooking appliance 100 is in the cooking mode.

[0036] In some embodiments, the heating power of the first heating device 30 can remain unchanged, the heating power of the second heating device 40 can be adjusted, and the heating power of the third heating device 40 can remain unchanged. Further, in this embodiment, the control component 60 can control the heating time of the first heating device 30, the heating power and / or heating time of the second heating device 40, and the heating time of the third heating device 50 during the cooking mode of the cooking appliance 100, so as to improve the uniformity of the temperature in the heating cavity 101.

[0037] In some embodiments, the control component 60 is also connected to the control panel on the housing component 10. When receiving an operation signal for any functional control, the control panel generates a corresponding electrical signal and sends it to the control component 60. The control component 60 can control the cooking appliance 100 based on the electrical signal. Optionally, the control component 60 can include a micro controller unit (MCU).

[0038] Please refer again Figure 1 In some embodiments, the cooking appliance 100 may further include a hot air blower 102. The hot air blower 102 is disposed in the housing assembly 10 and is located on a side away from the heating cavity 101 relative to the first heating device 30, and is used to blow air into the heating cavity 101 when the cooking appliance 100 is in the cooking mode. The hot air blower 102 is spaced apart from the first heating device 30, and the hot air blower 102 is also fixed in the housing assembly 10 by a fixed structure. In some embodiments, the hot air blower 102 may also be used to cause the high-temperature gas generated by the heating of the first heating device 30 to convectively circulate in the heating cavity 101, thereby keeping the food warm. It should be noted that the fixed structure for fixing the first heating device 30 may be the same as or different from the fixed structure for fixing the hot air blower 102.

[0039] Among them, the hot air blower 102 can be driven by a motor to rotate the fan blades to blow air, and can include multiple gears, such as high gear (speed above 2500rpm / min), medium gear (speed of 1500-2500rpm / min), low gear (speed below 1500rpm / min), etc. By way of example, the hot air blower 102 can include a fan with parameters of DC220V, 50Hz, and 1000W.

[0040] In which, when the cooking appliance 100 includes a hot air blower 102, the control component 60 is connected to the hot air blower 102 and is used to control the working parameters of the hot air blower 102, such as controlling the rotation speed and rotation time of the hot air blower 102.

[0041] In some embodiments, considering that the hot air blower 101 is located on the side away from the heating chamber 101 relative to the first heating device 30, the hot air blower 102 can accelerate the heat dissipation of the first heating device 30. In this embodiment, the maximum power of the first heating device 30 can be set to be greater than the maximum power of the third heating device 50, and the maximum power of the third heating device 50 can be set to be greater than the maximum power of the second heating device 40, so as to accelerate the efficiency of increasing the temperature of the heating chamber 101 and the uniformity of the temperature in the heating chamber 101.

[0042] In some embodiments, the cooking appliance 100 may further include a temperature detection device 70 (not shown), wherein the temperature detection device 70 can be used to detect the working temperature in the heating chamber 101, so that the cooking appliance 100 adjusts 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 cooking performance of the cooking appliance.

[0043] Please refer again Figure 1 In some embodiments, the temperature detection device 70 may include a first temperature detection device 103 and a second temperature detection device 104. The first temperature detection device 103 may be used to detect a first measured temperature near the first heating device 30, and the second temperature detection device 104 may be used to detect a second measured temperature near the third heating device 50. The first measured temperature and the second measured temperature may be used as the working temperature of the heating chamber 101. The first temperature detection device 103 is disposed in the housing assembly 10 and located above the heating chamber 101, and is used to detect the temperature above the heating chamber 101; the second temperature detection device 104 may be disposed below the bottom wall of the frying vat 20, and is used to detect the temperature of the bottom wall.

[0044] Among them, 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.; among them, the first temperature detection device 103 may be the same as the second temperature detection device 104 or different, which is not limited here.

[0045] When the cooking appliance 100 includes the first temperature detection device 103 and the second temperature detection device 104, the first temperature detection device 103 can be connected to the control component 60 to detect the temperature near the first heating device 30, such as the temperature above the heating chamber 101, and report the temperature as the first measured temperature to the control component 60, and the second detection device 103 can be connected to the control component 60 to detect the temperature near the third heating device 50, such as the temperature of the bottom wall of the frying bucket 20, and report the temperature as the second measured temperature to the control component 60.

[0046] Among them, the control component 60 can adjust the heating parameters of the first heating device 30, the second heating device 40 and the second heating device 50 based on the first measured temperature and the second measured temperature, so as to achieve precise control of the temperature of the heating chamber 101 and improve the uniformity of the temperature in the heating chamber 101.

[0047] In some embodiments, considering that the temperature resistance of the thermocouple detection circuit is higher than that of the NTC detection circuit, the hot air blower 102 can accelerate the heat dissipation of the first heating device 30. In this embodiment, the first temperature detection device 103 may include an NTC detection circuit, and the second temperature detection device 104 may include a thermocouple detection circuit to detect the temperature above the heating chamber 101 based on the NTC detection circuit, and to detect the temperature of the bottom wall of the frying barrel 20 based on the thermocouple detection circuit.

[0048] For example, see Figure 2 , which shows a schematic diagram of the connection between the first temperature detection device and the control component provided by an embodiment of the present application. The first temperature detection device 103 includes an NTC detection circuit, such as Figure 2 As shown; the controller 60 may include a main control chip, wherein the main control chip is connected to the NTC detection circuit. The NTC detection circuit is composed of resistors R1, R2, R3, thermistor CN071, capacitors C1 and C2 based on Figure 2 The components are connected in the manner shown.

[0049] For example, see Figure 3 , which shows a schematic diagram of the connection between the second temperature detection device and the control component provided by an embodiment of the present application. The second temperature detection device 104 includes a thermocouple detection circuit, such as Figure 3 As shown; the controller 60 may include a main control chip, wherein the main control chip is connected to a thermocouple detection circuit. The thermocouple detection circuit is composed of resistors R4, R5, R6, R7, R8, R9, R10, R11, a temperature sensor, capacitors C3, C4, C5, a comparator U021B and U021A based on the following Figure 3 The components are connected in the manner shown.

[0050] In some embodiments, the control component 60 can execute the cooking process after receiving the cooking instruction. During the cooking process, the control component 60 can determine the preset temperature and cooking time in response to the cooking appliance 100 being in the cooking mode. During the cooking time, the temperature detection device 70 detects the working temperature in the heating cavity 101, and based on the target size relationship between the working temperature and the preset temperature, controls the heating parameters of the first heating device 30, the second heating device 40 and the third heating device 50. In this way, by controlling the heating parameters of the three heat sources included in the cooking appliance 100 when the cooking appliance 100 is in the cooking mode, the three heat sources cooperate to generate heat to improve the uniformity of the temperature in the heating cavity 101, thereby improving the cooking performance of the cooking appliance 100.

[0051] See also Figure 4 , Figure 4 A flow chart of a control method for a cooking appliance provided by an embodiment of the present application is shown. The method arranges a first heating device, a second heating device, and a third heating device at different positions in a heating cavity, obtains the working temperature in the heating cavity in real time through a temperature detection device, and determines a preset temperature and cooking time when the cooking appliance is in a cooking mode. During the cooking time, the three heat sources included in the cooking appliance are controlled to heat with different heating parameters according to the relationship between the working temperature of the cooking appliance and the preset temperature, thereby improving the uniformity of the temperature in the heating cavity of the cooking appliance and enhancing the cooking performance of the cooking appliance. In a specific embodiment, the cooking method can be applied to Figure 7 The control device 200 of the cooking appliance and the cooking appliance 100 ( Figure 8 ). The following will take cooking utensils as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the cooking utensils used in this embodiment may include air fryers, ovens, microwave ovens, etc., which are not limited here. Figure 4 The process shown in FIG. 1 is described in detail, and the control method of the cooking appliance may specifically include the following steps:

[0052] Step S110: In response to the cooking appliance being in a cooking mode, determining a cooking time and a preset temperature.

[0053] In some embodiments, the cooking appliance may include working modes such as a cleaning mode, a cooking mode, a warm keeping mode, and a standby mode. In the cooking mode, the cooking appliance may cook the food placed in the cooking appliance; in the standby mode, the components included in the cooking appliance may be in a standby state, and the cooking appliance may receive a control instruction input by a user, and switch the working mode of the cooking appliance based on the control instruction. Exemplarily, the cooking appliance may receive a first cooking instruction input by a user in the standby mode, and cook the food placed in the cooking appliance in response to the first cooking instruction.

[0054] As an implementable manner, the cooking appliance may receive a first cooking instruction input by a user, wherein the first cooking instruction may carry a cooking time and a preset temperature. Accordingly, the cooking appliance may determine that it is necessary to control the cooking appliance to enter a cooking mode upon receiving the first heat preservation cooking instruction. Furthermore, the cooking appliance may parse the first cooking instruction to obtain the cooking time and the preset temperature carried by the first cooking instruction, and control the heating parameters of the three heat sources included in the cooking appliance based on the cooking time and the preset temperature to cook the food.

[0055] As another practicable manner, the preset temperature corresponding to the cooking appliance is fixed. The cooking appliance can receive a second cooking instruction input by a user, wherein the second keep warm instruction does not carry a preset temperature but carries a cooking time. Accordingly, the cooking appliance can determine that it is necessary to control the cooking appliance to enter a cooking mode upon receiving the second cooking instruction, and parse the second cooking instruction to determine the cooking time. Further, the cooking appliance can obtain a preset preset temperature, and control the heating parameters of the three heat sources included in the cooking appliance based on the cooking time and the fixed preset temperature to cook the food.

[0056] In some embodiments, the cooking appliance can determine a preset temperature and cooking time in response to the cooking appliance being in a cooking mode. Optionally, the cooking time can be set by the user or obtained through third-party experimental data, such as 1 minute, 20 minutes, 50 minutes, etc.; the preset temperature can be set by the user or obtained through third-party experimental data, such as 100°C, 120°C, 180°C, 200°C, etc., which are not limited here.

[0057] Exemplarily, the cooking appliance is an air fryer, which includes functions such as cooking, keeping warm, cooking porridge, and making soup. The user can select the button corresponding to the cooking function of the air fryer and press it, and can also set the cooking time and preset temperature, and press the button corresponding to the cooking function again to start the cooking appliance to enter the cooking mode. The cooking appliance can also enter the cooking mode after receiving the cooking time and preset temperature set by the user and timing the preset start time, and control the heating parameters of the three heat sources included in the cooking appliance based on the cooking time and preset temperature to cook food.

[0058] Step S120: During the cooking time, the temperature detection device detects the working temperature in the heating cavity.

[0059] In some embodiments, after the cooking appliance determines the cooking time, it can detect the working temperature in the heating cavity through the temperature detection device during the cooking time. Specifically, during the cooking time, the cooking appliance can detect a first measured temperature near the first heating device through the first temperature detection device, and use the first measured temperature as the working temperature in the heating cavity; the cooking appliance can also detect a second measured temperature near the third heating device through the second temperature detection device, and use the second measured temperature as the working temperature in the heating cavity.

[0060] The cooking appliance may also use the average value, median value, arithmetic mean value, etc. of the first measured temperature and the second detected temperature as the working temperature in the heating cavity.

[0061] Step S130: controlling heating parameters of the first heating device, the second heating device, and the third heating device according to a target size relationship between the operating temperature and the preset temperature.

[0062] In some embodiments, after the cooking appliance determines the preset temperature and the working temperature in the heating cavity, the heating parameters of the first heating device, the second heating device, and the third heating device included in the cooking appliance can be controlled according to the target size relationship between the working temperature and the preset temperature. The target size relationship between the working temperature and the preset temperature may include that the working temperature is greater than the preset temperature, the working temperature is less than the preset temperature, etc.

[0063] As an practicable manner, the first heating device may include a heating tube, and further, the cooking appliance may control the heating parameters of the heating tube, such as heating power, heating time, etc. Exemplarily, the cooking appliance may control the heating tube to heat based on a first preset power, wherein the first preset power may include the maximum power of the heating tube, and the cooking appliance may also control the heating time of the heating tube, such as controlling the heating tube to heat at the maximum power based on the first periodic interval. Wherein, heating at the maximum power may be understood as heating at full power.

[0064] As another practicable manner, the second heating device may include a heating belt, and further, the cooking appliance may control heating parameters of the heating belt, such as heating power, heating time, etc. Exemplarily, the cooking appliance may control the heating belt to heat at a first preset power, wherein the first preset power may include the maximum power of the heating belt, or may include a power lower than the maximum power of the heating belt.

[0065] As another practicable manner, the third heating device may include an infrared dish, and further, the cooking appliance may control heating parameters of the infrared dish, such as heating power, heating time, etc. Exemplarily, the cooking appliance may control the infrared tube dish to heat at a first preset power, wherein the first preset power may include the maximum power of the infrared dish, and the cooking appliance may also control the heating time of the infrared dish, such as controlling the infrared tube to heat at the maximum power based on the second periodic interval.

[0066] Optionally, the first period and the second period may be equal or unequal, wherein the first period may be set independently by the user or obtained through third-party experimental data, such as heating for 10 seconds at an interval of 5 seconds, etc.; the second period may be set independently by the user or obtained through third-party experimental data, such as heating for 10 seconds at an interval of 5 seconds, etc., which is not limited here.

[0067] In some embodiments, the cooking appliance can control the hot air blower to rotate during the cooking mode to circulate hot air and increase the rate of heat flow. Exemplarily, during the cooking mode, the hot air blower can be controlled to rotate at a low gear, a medium gear, or a high gear.

[0069] A cooking method provided by an embodiment of the present application determines a preset temperature and a cooking time in response to a cooking appliance being in a cooking mode; during the cooking time, a temperature detection device detects the working temperature in a heating cavity, and controls heating parameters of a first heating device, a second heating device, and a third heating device based on the preset temperature and the cooking time; and further, by controlling the coordinated heating of the three heat sources included in the cooking appliance while the cooking appliance is in the cooking mode, the uniformity of the temperature in the heating cavity of the cooking appliance is improved, thereby improving the cooking performance of the cooking appliance.

[0070] See also Figure 5 , Figure 5 The flow chart of the control method of the cooking appliance provided by an embodiment of the present application is shown. The method is applied to the above cooking appliance. Figure 5 The process shown in FIG. 1 is described in detail, and the control method of the cooking appliance may specifically include the following steps:

[0071] Step S210: When the cooking appliance is in the cooking mode, the cooking time and the preset temperature are determined.

[0072] For the specific description of step S210, please refer to the specific description of step S110 above, which will not be repeated here.

[0073] Step S220: obtaining a first magnitude relationship between the first measured temperature and a first preset temperature, and / or obtaining a second magnitude relationship between the second measured temperature and a second preset temperature.

[0074] In some embodiments, the temperature detection device includes a first temperature detection device and a second temperature detection device, the first temperature detection device can be used to detect a first measured temperature near the first heating device, and the second temperature detection device can be used to detect a second measured temperature near the third heating device.

[0075] In some embodiments, after the cooking appliance obtains a first measured temperature, the first temperature can be compared with a first preset temperature to obtain a first size relationship; after the cooking appliance obtains a second measured temperature, the second measured temperature can be compared with a second preset temperature to obtain a second size relationship.

[0076] The first preset temperature can be calculated from the preset temperature and the first adjustment temperature; the second preset temperature can be calculated from the preset temperature and the second adjustment temperature. Exemplarily, the first preset temperature = preset temperature - first adjustment temperature, the second preset temperature = preset temperature - second adjustment temperature; wherein the second adjustment temperature can be greater than the first adjustment temperature.

[0077] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the second temperature detection device includes a thermocouple detection circuit. Considering that the temperature detection deviation of the thermocouple detection circuit is larger than the temperature detection deviation of the NTC detection circuit, in this embodiment, the cooking appliance can set the NTC first impulse offset temperature, which can be understood as the first adjustment temperature, such as the first adjustment temperature can be set to above 10°C; the cooking appliance can set the thermocouple first impulse offset temperature, which can be understood as the second adjustment temperature, such as the second adjustment temperature can be set to above 20°C. Among them, the second adjustment temperature can be greater than the first adjustment temperature.

[0078] Step S230: controlling heating parameters of the first heating device, the second heating device, and the third heating device according to the first size relationship and / or the second size relationship.

[0079] In some embodiments, after the cooking appliance obtains the first size relationship and / or the second size relationship, the heating parameters of the first heating device, the second heating device and the third heating device can be controlled according to the first size relationship and / or the second size relationship.

[0080] In some embodiments, the cooking appliance can control at least two of the first heating device, the second heating device, and the third heating device to continue heating at their respective first preset powers in response to the first measured temperature being less than the first preset temperature and / or the second measured temperature being less than the second preset temperature. The first preset power can correspond to the maximum power, full power, etc. of each heating device.

[0081] The process in which the cooking appliance controls the first heating device, the second heating device and the third heating device to continuously heat at maximum power can be understood as the initial charging stage in the cooking process. The process in which the first heating device, the second heating device and the third heating device continuously heat at maximum power can be understood as the first heating device, the second heating device and the third heating device all heating at full power.

[0082] In some embodiments, when the cooking appliance controls the first heating device, the second heating device, and the third heating device to heat at full power, the hot air blower can be controlled to rotate to speed up the circulation of hot air in the heating cavity, so that the heat flows quickly to various positions in the heating cavity, thereby improving the temperature uniformity of the cooking appliance during cooking.

[0083] Exemplarily, the first heating device includes a heating tube, the second heating device includes a heating belt, and the third heating device includes an infrared tube. When the cooking appliance enters the cooking mode, the heating tube, the heating belt, and the infrared tube can be controlled to heat at full power; optionally, the cooking appliance can control the hot air blower to rotate at a medium or high gear to increase the rate of heat flow. Among them, if the preset temperature is 100°C, the cooking appliance can boil the water in the fryer to a near-boiling state during the full-power heating stage, and then control the three heat sources of the cooking appliance to heat together to achieve the cooking function.

[0084] In this embodiment, when the cooking appliance is in the cooking mode, the temperature above the heating chamber detected by the first temperature detection device can be obtained in real time as the first measurement temperature, and the temperature of the bottom wall of the frying barrel detected by the second temperature detection device can be obtained in real time as the second measurement temperature.

[0085] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the second temperature detection device includes a thermocouple detection device. When the heating cavity is in a cooking mode, the cooking appliance can obtain the temperature above the heating cavity detected by the NTC detection circuit as the first measurement temperature, and obtain the temperature of the bottom wall detected by the thermocouple detection circuit as the second measurement temperature.

[0086] In some embodiments, after the cooking appliance obtains the first size relationship and the second size relationship, the heating parameters of the first heating device, the second heating device, and the third heating device can be controlled according to the first size relationship and the second size relationship.

[0087] As an implementation method, the cooking appliance can control the first heating device to heat for a first preset time period at a first time interval based on maximum power in response to the first measured temperature being not less than the first preset temperature, and / or the second measured temperature being not less than the second preset temperature, and can also control the third heating device to heat for a second preset time period at a second time interval based on maximum power, and can also control the second heating device to continue heating based on maximum power; the first heating device can also be controlled to heat for the first preset time period at a second preset power at a first time interval, and / or the third heating device can heat for the second preset time period at a third preset power at a second time interval, and / or the second heating device can heat for the third preset time period at a fourth preset power at a third time interval.

[0088] Among them, the first measured value is greater than the first set temperature, and / or the second measured temperature is greater than the second set temperature, which can be understood as the temperature of the first impulse stage of the cooking appliance exceeds the first impulse temperature, and the cooking appliance can be controlled to enter the next stage, such as controlling the first heating device to heat the first preset time at a first time interval with a second preset power, controlling the third heating device to heat the second preset time at a second time interval with a third preset power, and controlling the second heating device to maintain continuous heating based on maximum power.

[0089] The first time interval may be pre-set in the cooking appliance, and the cooking appliance may also obtain the first time interval from an associated electronic device or the cloud through wireless communication technology. The first time interval may be set by the user or obtained through third-party experimental data, which is not limited here. For example, the first time interval is 5 seconds, 6 seconds, etc.

[0090] The first preset time length can be pre-set in the cooking appliance, and the cooking appliance can also obtain the first preset time length from an associated electronic device or the cloud through wireless communication technology. The first preset time length can be set by the user independently or obtained through third-party experimental data, which is not limited here. For example, the first preset time length is 10 seconds, 11 seconds, etc.

[0091] The second preset power may include the maximum power of the first heating device, may be equal to the first preset power of the first heating device, or may be less than the first preset power, which is not limited here.

[0092] Exemplarily, after determining that the first measured temperature is greater than the first preset temperature and the second measured temperature is greater than the second preset temperature, the cooking appliance can control the first heating device to heat at an interval of (x1, y1) based on the maximum power, wherein x1 represents the first preset heating time, y1 represents the heating cycle, and (y1-x1) represents the first time interval. x1 can be set to more than 5 seconds, or more than 0 seconds; y1 can be set to more than 10 seconds.

[0093] The second time interval can be pre-set in the cooking appliance, or obtained from an associated electronic device or cloud through wireless communication technology. The second time interval can be set by the user or obtained through third-party experimental data; the method for obtaining the second time interval can be the same as or different from the method for obtaining the first time interval, and the first time interval and the second time interval can be equal or different, which is not limited here. Exemplarily, the second time interval is 5 seconds, 6 seconds, etc.

[0094] The second preset duration can be pre-set in the cooking appliance, or obtained from an associated electronic device or the cloud through wireless communication technology. The second preset duration can be set by the user independently, or obtained through third-party experimental data, which is not limited here; the method for obtaining the second preset duration can be the same as or different from the method for obtaining the first preset duration, and the first preset duration can be equal to or different from the preset duration, which is not limited here. Exemplarily, the second preset duration is 10 seconds, 11 seconds, etc.

[0095] The third preset power may include the maximum power of the third heating device, may be equal to the first preset power of the third heating device, or may be less than the first preset power, which is not limited here.

[0096] For example, after determining that the first measured temperature is greater than the first preset temperature and the second measured temperature is greater than the second preset temperature, the cooking appliance can control the third heating device to heat at an interval of (x2, y2) based on the maximum power, wherein x2 represents the second preset heating time, y2 represents the heating cycle, and (y2-x2) represents the second time interval. x2 can be set to more than 5 seconds; y2 can be set to more than 10 seconds.

[0097] Wherein, while controlling the first heating device and the third heating device to heat at intervals based on the maximum power, the cooking appliance can also control the second heating device to heat at a fourth preset power at a third time interval, wherein the fourth preset power can be equal to the maximum power of the second heating device, or can be equal to the first preset power of the second heating device, or can be less than the first preset power, which is not limited here. Exemplarily, the cooking appliance can control the second heating device to continue heating based on the maximum power.

[0098] In some embodiments, while controlling the first heating device and the third heating device to perform interval heating based on maximum power, and controlling the second heating device to perform continuous heating based on maximum power, the cooking appliance can also control the hot air blower to rotate, such as controlling the hot air blower to rotate at a medium or high gear.

[0099] As an implementable manner, the cooking appliance can also obtain the first measured temperature and / or the second measured temperature in real time after controlling the first heating device to heat for a first preset time period based on maximum power at a first time interval, controlling the third heating device to heat for a second preset time period based on maximum power at a second time interval, and controlling the second heating device to maintain continuous heating based on maximum power. If the first measured temperature is not less than the third preset temperature, and / or the second measured temperature is not less than the fourth preset temperature, the first heating device and / or the third heating device can be controlled to stop heating, and the second heating device can be controlled to heat based on a fifth preset power.

[0100] The third preset temperature can be calculated from the preset temperature and the third adjustment temperature; the fourth preset temperature can be calculated from the preset temperature and the fourth adjustment temperature. Exemplarily, the third preset temperature = preset temperature - third adjustment temperature, and the fourth preset temperature = preset temperature - third adjustment temperature.

[0101] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the second temperature detection device includes a thermocouple detection circuit. Considering that the temperature detection deviation of the thermocouple detection circuit is larger than the temperature detection deviation of the NTC detection circuit, in this embodiment, the cooking appliance can set an offset temperature value of the NTC set temperature, and the third adjustment temperature can be understood, such as the third adjustment temperature can be set to above 1°C; the cooking appliance can set an offset temperature value of the thermocouple set temperature, and the fourth adjustment temperature can be understood, such as the fourth adjustment temperature can be set to above 10°C. Among them, the fourth adjustment temperature can be greater than the third adjustment temperature.

[0102] Among them, the first measured temperature is not less than the third preset temperature, and / or the second measured temperature is not less than the fourth preset temperature, which can be understood as the temperature of the controlled interval heating of the cooking appliance exceeds the interval heating temperature, and the cooking appliance can be controlled to enter the temperature balance maintenance stage, such as controlling the first heating device and the third heating device to stop heating, and controlling the second heating device to heat based on the fifth preset power.

[0103] Exemplarily, the first heating device includes a heating tube, the second heating device includes a heating belt, and the third heating device includes an infrared tube. The cooking appliance is controlled to enter the temperature balance maintenance stage, the heating tube and the infrared tube can be controlled to stop heating, and the heating belt can be adjusted to maintain low power according to the actual menu performance of the cooking appliance, such as controlling the heating belt to heat based on a second preset power, wherein the target power is lower than the maximum power of the heating belt, which can be understood as a low-concept power of the heating belt, such as a power below 200 watts, thereby maintaining the temperature balance in the heating chamber.

[0104] In some embodiments, the cooking appliance further includes a fan, which is used to provide a circulating airflow to the heating chamber. In the process of entering the temperature balance maintenance stage, the cooking appliance can control the hot air blower to adjust the gear and rotate. It can be understood that the cooking appliance can control the fan to operate at the first wind speed in response to the second heating device heating at the fifth preset power. Exemplarily, the high-speed rotation of the hot air blower can be adjusted to the middle-speed rotation, and the middle-speed rotation of the hot air blower can be adjusted to the low-speed rotation, which is not limited here. In particular, if the preset temperature is 100°C, the fan can also play a role in eliminating boiling bubbles during the cooking process. This stage can be understood as the boiling stage of cooking to maintain a slightly boiling state.

[0105] As another practicable manner, after controlling the first heating device to heat for a first preset time period at a first time interval based on maximum power, controlling the third heating device to heat for a second preset time period at a second time interval based on maximum power, and controlling the second heating device to keep heating based on maximum power, if the first measured temperature is less than the third preset temperature, and / or the second measured temperature is less than the fourth preset temperature, the first heating device can be controlled to heat for a fourth preset time period at a fourth time interval at a sixth preset power, and / or the third heating device can be controlled to heat for a fifth preset time period at a fifth time interval at a seventh preset power, and / or the second heating device can be controlled to heat for a sixth preset time period at a sixth time interval at an eighth preset power; the cooking device can also be controlled to keep heating at the controlled interval, such as controlling the first heating device to keep heating for the first preset time period at a first time interval based on maximum power, controlling the third heating device to keep heating for the second preset time period at a second time interval based on maximum power, and controlling the second heating device to keep heating based on maximum power.

[0106] Among them, the sixth preset power can be equal to the maximum power of the first heating device, or less than the maximum power of the first heating device, which is not limited here; the seventh preset power can be equal to the maximum power of the third heating device, or less than the maximum power of the third heating device, which is not limited here; the eighth preset power can be equal to the maximum power of the second heating device, or less than the maximum power of the second heating device, which is not limited here.

[0107] As another practicable manner, after the cooking appliance controls the first heating device and the third heating device to stop heating, and controls the second heating device to heat based on the fifth preset power, if the first measured temperature is less than the fifth set temperature, or the second measured temperature is less than the sixth set temperature, the first heating device, the second heating device, and the third heating device can be controlled to return to the interval heating stage of the cooking appliance. The fifth preset temperature is calculated by the preset temperature and the fifth adjustment temperature; the sixth preset temperature is calculated by the preset temperature and the sixth adjustment temperature. Exemplarily, the fifth preset temperature = preset temperature - fifth adjustment temperature, and the sixth preset temperature = preset temperature - sixth adjustment temperature.

[0108] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the second temperature detection device includes a thermocouple detection circuit. Considering that the temperature detection deviation of the thermocouple detection circuit is larger than the temperature detection deviation of the NTC detection circuit, in this embodiment, the cooking appliance can set an offset value for NTC working temperature recovery, and the fifth adjustment temperature can be understood, such as the fifth adjustment temperature can be set to above 2°C; the cooking appliance can set an offset value for thermocouple working temperature recovery, and the sixth adjustment temperature can be understood, such as the sixth adjustment temperature can be set to above 12°C; wherein the sixth adjustment temperature is greater than the fifth adjustment temperature.

[0109] In this embodiment, the process of the cooking appliance in the cooking mode may include an initial charging stage, an interval heating stage, and a temperature balance maintaining stage, etc. The cooking appliance can control the heating parameters of the first heating device, the second heating device, and the third heating device according to the first measured temperature, the second measured temperature, and the preset temperature, so that the cooking appliance cycles through the stages included in the cooking mode until the time when the cooking appliance enters the cooking mode reaches the cooking time, and then the cooking appliance is controlled to return to the standby mode, thereby improving the temperature control accuracy of the cooking appliance in the cooking mode, improving the temperature uniformity in the heating cavity of the cooking appliance, and improving the cooking performance of the cooking appliance.

[0110] The cooking method provided in one embodiment of the present application is Figure 4 According to the cooking method shown in the figure, the present embodiment can also control the first heating device, the second heating device and the third heating device to continuously heat based on the maximum power within the cooking time; obtain the temperature above the heating cavity as the first temperature, and obtain the temperature of the bottom wall as the second temperature; control the heating parameters of the first heating device, the second heating device and the third heating device according to the first size relationship between the first temperature and the preset temperature and the second size relationship between the second temperature and the preset temperature, and then control the heating parameters of the three heat sources included in the cooking utensil according to the relationship between the first temperature and the preset temperature and the relationship between the second temperature and the preset temperature within the cooking time, thereby improving the temperature control accuracy of the cooking utensil in the cooking mode and improving the cooking performance of the whole machine.

[0112] Step S310: In response to the cooking appliance being in a cooking mode, determining a cooking time and a preset temperature.

[0113] Step S320: obtaining a first magnitude relationship between the first measured temperature and a first preset temperature, and / or obtaining a second magnitude relationship between the second measured temperature and a second preset temperature.

[0114] Step S330: controlling heating parameters of the first heating device, the second heating device, and the third heating device according to the first size relationship and / or the second size relationship.

[0115] For the detailed description of step S310 to step S330, please refer to the detailed description of step S210 to step S240 above, which will not be repeated here.

[0116] Step S340: If the first temperature is greater than the first over-temperature protection temperature or the second temperature is greater than the second over-temperature protection temperature, the first heating device, the second heating device and the third heating device are controlled to stop heating.

The cooking appliance 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.

[0119] In some embodiments, when the cooking appliance obtains the first measured temperature and the second measured temperature in real time, the first measured temperature obtained in real time can be compared with the first over-temperature protection temperature, and / or the second measured temperature obtained in real time can be compared with the second over-temperature protection temperature. If the first measured temperature is greater than the first over-temperature protection temperature or the second measured temperature is greater than the second over-temperature protection temperature, the first heating device, the second heating device and the third heating device can be controlled to stop heating, and 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.

[0120] In some embodiments, after the cooking appliance controls all heating loads included in the cooking appliance to stop working, if it is determined that the first measured temperature and the second measured temperature are both less than the operating temperature threshold, the cooking appliance can be controlled to return to step S310 to perform a normal cooking procedure.

[0121] The operating temperature threshold may be set by the user, or obtained through third-party experimental data; may be pre-set in the cooking appliance, or may be obtained by the cooking appliance from an associated electronic device or the cloud. For example, the operating temperature threshold may be below 105°C.

[0122] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the ultra-high temperature protection temperature corresponding to the first temperature detection device is obtained to be above 200°C according to the third-party experimental data. Further, the user can set the first ultra-high temperature protection temperature to 200°C according to the ultra-high temperature protection temperature; the second temperature detection device includes a thermocouple detection circuit, and the ultra-high temperature protection temperature corresponding to the second temperature detection device is obtained to be above 300°C according to the third-party experimental data. Further, the user can set the first ultra-high temperature protection temperature to 300°C according to the ultra-high temperature protection temperature. If the cooking appliance detects that the first measured temperature is greater than the first ultra-high temperature protection temperature or the second measured temperature is greater than the second ultra-high temperature protection temperature, the heating load included in the cooking appliance can be controlled to stop working. Further, after the cooking appliance controls the heating load to stop working, the first measured temperature and the second measured temperature can be detected in real time. If it is determined that the first measured temperature and the second measured temperature are both less than 105°C, the cooking appliance can be controlled to continue to control the heating parameters of the first heating device, the second heating device and the third heating device according to the cooking time and the preset temperature, thereby ensuring the cooking safety and improving the cooking performance of the cooking appliance.

When the cooking utensil is in the cooking mode, the safety of the cooking utensil is ensured. At the same time, the heating parameters of the three heat sources included in the cooking utensil are controlled to coordinate the heating, thereby improving the cooking performance of the cooking utensil.
