The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present application and should not be construed as limiting the present application.

[0026] In order to enable those skilled in the art to better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0027] With the rapid development of the social economy, people's lives are becoming more and more affluent, and the number of large and small household appliances in people's homes is gradually increasing as their lives become more prosperous. However, within the limited space of the user's existing housing, due to too many household appliances, the user's activity range is gradually shrinking. Therefore, the trend of complete and integrated functions of household appliance products is very necessary.

[0028] In the related art, due to the integration of product functions, there are bound to be many problems to be solved, such as temperature rise problems, reliability problems of heating systems, food performance problems, etc. These problems require that within a narrow structural space, the operating environment temperature of electronic components should be lower than their own operating temperature requirements to solve, otherwise the electronic components will have problems of poor reliability and short life. Among them, the integration of different product functions requires a high level of reliability for electronic devices. For example, it is necessary to effectively manage the hot and cold systems of products. Among them, realizing reliable thermal system management has become a key task for all high-performance electronic systems.

[0029] In view of the above problems, the inventors have found through long-term research and proposed a cooking appliance, a cooking method, and a device provided by an embodiment of the present application. By controlling the operation of a heating element corresponding to a cooking mode when the cooking appliance is in different cooking modes, the cooking performance of the cooking appliance is improved while ensuring the safety of cooking. Among them, the specific cooking method will be described in detail in the subsequent embodiments.

[0030] Please refer to Figure 1 and Figure 2 , where Figure 1 shows a schematic structural diagram of a cooking appliance provided by an embodiment of the present application, Figure 2 shows a schematic diagram of a cooking appliance provided by an embodiment of the present application. In the embodiment of the present application, the cooking appliance 10 may include a housing assembly 11, a frying barrel 12, a first heating element 13, a second heating element 14, and a control assembly 15.

[0031] Among them, the outer shell assembly 11 is provided with a receiving cavity, and the frying barrel 12 is movably arranged in the receiving cavity. The frying barrel 12 may include a bottom wall and a peripheral wall. The peripheral wall is circumferentially connected to the periphery of the bottom wall to jointly form a cooking cavity for accommodating food. The first heating element 13 is arranged in the outer shell assembly 11 and is located above the cooking cavity; the second heating element 14 is arranged in the outer shell assembly 11 and is located below the bottom wall. The control assembly 15 is respectively connected to the first heating element 13 and the second heating element 14, and is configured to control the first heating element 13 to work and the second heating element 14 not to work when it is determined that the cooking appliance 10 is in the first cooking mode, or to control the second heating element 14 to work and the first heating element 13 not to work when it is determined that the cooking appliance 10 is in the second cooking mode.

[0032] Among them, the cooking appliance 10 may have functions such as cooking and heat preservation. The cooking appliance 10 can generate hot air through the first heating element 13 and the second heating element 14, and then make the hot air circulate rapidly in a sealed space through a hot air convection system, so as to realize the method of heating food. In the embodiments of the present application, the cooking appliance 10 may be an air fryer with a cooking function, such as Figure 2 shown.

[0033] Among them, according to Figure 2 it can be seen that the outer shell assembly 11 plays a supporting role. The outer shell assembly 11 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 the direction perpendicular to the plane where the bottom cover is located. One side of the side wall is circumferentially connected to the periphery of the bottom cover, and the other side is circumferentially connected to the periphery of the top plate. The outer shell assembly 11 is provided with a receiving cavity for receiving the frying barrel 12. The side wall is formed with an opening for placing the frying barrel 12 in the receiving cavity.

[0034] In some embodiments, a control panel is provided on the outer surface of the side wall of the outer shell assembly 11 or the surface of the top plate away from the bottom cover. The control panel includes one or more function controls, and the above function controls include but are not limited to a start control, a reservation control, a time setting control, a mode setting control, a food type setting control, etc.

[0035] The frying barrel 12 may be movably arranged in the receiving cavity. When the frying barrel 12 is arranged in the receiving cavity, a handle is provided on the surface of the frying barrel 12 exposed from the receiving cavity for the user to grip. The frying barrel 12 includes a bottom wall and a peripheral wall, and the peripheral wall is circumferentially connected to the periphery of the bottom wall to jointly form a cooking cavity for accommodating food.

[0036] Among them, the first heating element 13 and the second heating element 14 can be used to implement the cooking function of the cooking appliance 10. Optionally, the first heating element 13 can include a heating tube, an infrared heating plate, etc., and the second heating element 14 can include a heating belt, a heating tube, etc., which are not limited herein; among them, the first heating element 13 and the second heating element 14 can be the same heating device or different heating devices; among them, the maximum power of the first heating element 13 and the second heating element 14 can be the same or different.

[0037] Exemplarily, the maximum power of the first heating element 13 can be greater than the maximum power of the second heating element 14. For example, the first heating element 13 can include a high-power heating tube, and the second heating element 14 can include a medium-power infrared tube; the first heating element 13 can include a heating tube with parameters of AC voltage 220V, 50Hz, 1000W, and the second heating element 14 can include an infrared tube with parameters of AC220V, 50Hz, 500W.

[0038] In some embodiments, the first heating element 13 can be correspondingly arranged with the cooking cavity and is fixedly arranged in the housing assembly 11 through a fixing structure, and is used to generate heat when the cooking appliance 10 is in the cooking mode, so as to raise the temperature of the gas in the cooking cavity. The second heating element 14 can be arranged in the housing assembly 11 corresponding to the bottom wall of the frying barrel 12 and is used to generate heat when the cooking appliance 10 is in the cooking mode, so as to raise the temperature of the gas in the cooking cavity. It should be noted that the fixing structure for fixing the first heating element 13 and the fixing structure for fixing the second heating element 14 can be the same or different.

[0039] In some embodiments, considering that the heat radiation range of the infrared disk is wider than the heating range of the heating tube, in this embodiment, the second heating element 14 can include an infrared heating disk, and then the bottom wall of the frying barrel 12 and the bottom of the cooking cavity are heated based on the infrared disk with a larger heat dissipation range, improving the temperature uniformity in the cooking cavity when the cooking appliance 10 cooks food.

[0040] In this embodiment, the control component 15 is respectively connected to the first heating element 13 and the second heating element 14, and is used to control the heating parameters of the first heating element 13 and the second heating element 14 during the cooking process of the cooking appliance 10.

[0041] In some embodiments, the heating power of the first heating element 13 can remain unchanged, and the heating power of the second heating element 14 can remain unchanged. Further, in this embodiment, the control component 15 can control the heating time of the first heating element 13 and the heating time of the second heating element 14 during the cooking process of the cooking appliance 10 to improve the cooking performance of the cooking appliance.

[0042] In this embodiment, the cooking appliance 10 may include multiple cooking modes, such as a first cooking mode, a second cooking mode, etc.; among them, the first cooking mode may be an air fry cooking mode, and the second cooking mode may be a pressure cooking mode, which is not limited herein. Among them, when the cooking appliance 10 is in different cooking modes, the heating object controlled by the control component 15 to generate heat may be different or the same, which is not limited herein. Exemplarily, the heating object corresponding to the first cooking mode may be the first heating element 13, and the heating object corresponding to the second cooking mode may be the second heating element 14.

[0043] Correspondingly, when it is determined that the cooking appliance 10 is in the first cooking mode, the cooking appliance 10 can control the first heating element 13 to work and control the second heating element 14 not to work through the control component 15, or when it is determined that the cooking appliance 10 is in the second cooking mode, control the second heating element 14 to work and control the first heating element 13 not to work.

[0044] In some embodiments, the control component 15 is also connected to the control panel on the housing component 11. When the control panel receives an operation signal for any one of the function controls, it generates a corresponding electrical signal and sends it to the control component 15. The control component 15 can control the cooking appliance 10 based on this electrical signal. Optionally, the control component 15 may include a Micro Controller Unit (MCU).

[0045] Please refer to again Figure 2 , in some embodiments, the cooking appliance 10 may further include a hot air blower 101. The hot air blower 101 is disposed in the housing component 11, and is located on a side away from the cooking cavity relative to the first heating element 13 and is connected to the control component 15 for blowing air into the cooking cavity. The hot air blower 101 is spaced apart from the first heating element 13, and the hot air blower 101 is also fixedly disposed in the housing component 11 through a fixing structure.

[0046] In some embodiments, the hot air blower 101 can also be used to cause the high-temperature gas generated by the heating of the first heating element 13 to undergo convective circulation in the cooking cavity, thereby heating the food. It should be noted that the fixing structure for fixing the first heating element 13 and the fixing structure for fixing the hot air blower 101 may be the same or different.

[0047] Among them, the hot air blower 101 can drive the fan blade to rotate and blow air by a motor, and can include multiple gears, such as a high gear (rotation speed above 2500 rpm / min), a medium gear (rotation speed of 1500 - 2500 rpm / min), a low gear (rotation speed below 1500 rpm / min), etc. Exemplarily, the hot air blower 101 can include a fan with parameters of AC220V, 50Hz, and 25W.

[0048] Wherein, when the cooking appliance 10 includes a hot air blower 101, the control component 15 can be connected to the hot air blower 101 for controlling the operating parameters of the hot air blower 101, such as controlling the rotation speed, rotation duration, etc. of the hot air blower 101. Exemplarily, the control component 15 can control the hot air blower 101 included in the cooking appliance 10 to rotate continuously when it is determined that the cooking appliance 10 is in the first cooking mode; or when it is determined that the cooking appliance 10 is in the second cooking mode, control the hot air blower 101 included in the cooking appliance 10 to rotate during the process when the second heating element 14 stops heating.

[0049] In some embodiments, considering that the hot air blower 101 is located on a side away from the cooking cavity relative to the first heating element 13, the hot air blower 101 can accelerate the heat dissipation of the first heating element 13. In this embodiment, the maximum power of the first heating element 13 can be set to be greater than the maximum power of the second heating element 14 to improve the heating efficiency and the temperature uniformity in the cooking cavity.

[0050] Please refer to again Figure 2 , in some embodiments, the cooking appliance 10 may further include a first temperature acquisition circuit 102 and a second temperature acquisition circuit 103. Wherein, the first temperature acquisition circuit 102 can be arranged in the housing assembly 11 and above the cooking cavity for detecting the temperature above the cooking cavity; the second temperature acquisition circuit 103 can be arranged in the housing assembly 11 and below the bottom wall of the frying barrel 12 for detecting the temperature of the bottom wall.

[0051] Wherein, the first temperature acquisition circuit 102 can include a thermocouple detection circuit, a thermistor NTC detection circuit, etc., and the second temperature acquisition circuit 103 can include a thermocouple detection circuit, an NTC detection circuit, etc.; wherein, the first temperature acquisition circuit 102 can be the same as or different from the second temperature acquisition circuit 103, which is not limited herein.

For example, the thermocouple detection circuit can be composed of a thermocouple sensor, one or more resistance elements, one or more capacitance elements, one or more comparators and other elements; the NTC detection circuit can be composed of multiple circuit elements. For example, the NTC detection circuit is composed of an NTC sensor, one or more resistance elements, one or more capacitance elements, one or more comparators and other elements.

[0053] When the cooking appliance 10 includes a first temperature acquisition circuit 102 and a second temperature acquisition circuit 103, the control component 15 can be respectively connected to the first temperature acquisition circuit 102 and the second temperature acquisition circuit 103, and is used to control the heating parameters of the first heating element 13 and the second heating element 14 according to the temperature acquired by the first temperature acquisition circuit 102 and / or the temperature acquired by the second temperature acquisition circuit 103, such as heating power, heating time, etc., so as to realize precise control of the temperature in the cooking cavity and improve the uniformity of the temperature in the cooking cavity.

[0054] In some embodiments, considering that the temperature resistance performance of the thermocouple detection circuit is higher than that of the NTC detection circuit, the hot air blower 101 can accelerate the heat dissipation of the first heating element 13. In this embodiment, the first temperature acquisition circuit 102 can adopt an NTC detection circuit, and the second temperature acquisition circuit 103 can adopt a thermocouple detection circuit to detect the temperature above the cooking cavity based on the NTC detection circuit and detect the temperature of the bottom wall of the frying bucket 12 based on the thermocouple detection circuit.

[0057] Please refer to Figure 5, in some embodiments, the cooking appliance 10 may further include a first detection circuit 104 and a second detection circuit 105. Among them, the first detection circuit 104 may be connected to the first heating element 13 for detecting the operating state of the first heating element 13; the second detection circuit 105 may be connected to the second heating element 14 for detecting the operating state of the second heating element 14.

For example, it may be composed of one or more resistance elements, one or more diodes, etc., which are not limited herein.

[0059] When the cooking appliance 10 includes the first detection circuit 104 and the second detection circuit 105, the control component 15 may be respectively connected to the first detection circuit 104 and the second detection circuit 105 for obtaining the self-check result of the cooking appliance 10 according to the operating state of the first heating element 13 detected by the first detection circuit 104 and the operating state of the second heating element 14 detected by the second detection circuit 105. Furthermore, when it is determined that the self-check of the cooking appliance 10 is completed and the self-check result is that each module is operating normally, the control component 15 controls the cooking appliance 10 to enter the cooking mode to improve the cooking safety and cooking performance of the cooking appliance 10.

[0060] Exemplarily, please refer to Figure 6 , which shows the circuit diagram of the first detection circuit provided by an embodiment of the present application.

[0062] In some embodiments, the cooking appliance 10 may further include a first heating control circuit 106 (not shown in the figures) and a second heating control circuit 107 (not shown in the figures). Among them, the control component 15 may be respectively connected to the first heating control circuit 106 and the second heating control circuit 107. Among them, the first heating control circuit 106 may be understood as the control circuit of the air fryer heating tube, and the second heating control circuit 107 may be understood as the pressure cooker load control circuit.

[0063] Optionally, the first heating control circuit 106 may be composed of multiple circuit elements. For example, it may be composed of one or more resistor elements, one or more diodes, one or more electronic switches and other elements; the second heating control circuit 107 may be composed of multiple circuit elements. For example, it may be composed of one or more resistor elements, one or more diodes, one or more electronic switches and other elements, which are not limited herein.

[0064] When the cooking appliance 10 includes the first heating control circuit 106 and the second heating control circuit 107, the control component 15 may be respectively connected to the first heating control circuit 106 and the second heating control circuit 107, for obtaining the working state of the first heating element 13 detected by the first heating control circuit 106 and the working state of the second heating element 14 detected by the second heating control circuit 107, and detecting the working conditions of the two heating source loads according to the two detection circuits, so as to control the two heating source loads to work separately, realize that the temperature rise inside the whole machine is within the design requirements, realize the effective management of the product's cold and heat system, make the heat system management reasonable, and no longer be the main influencing factor affecting the normal operation of the electronic circuit subsystem, so that all high-performance electronic systems can operate efficiently and orderly, and give full play to the best working performance of the cooking appliance 10.

[0065] Exemplarily, please refer to again Figure 6 which shows a schematic diagram of the first heating control circuit provided by an embodiment of the present application. Among them, the first heating control circuit 106 may be composed of electronic devices such as a relay KC1, diodes D3, D4, a voltage stabilizing diode ZD1, transistors Q1, Q2, Q3, Q4, resistors R13, R14, R15, R16, etc. based on the way as Figure 6 shown to form two IO port control circuits HTOP and HEAT.

[0066] Exemplarily, please refer to again Figure 7 which shows the circuit diagram of the second heating control circuit provided by an embodiment of the present application. Among them, the second heating control circuit 107 may be composed of electronic devices such as a relay KC2, a diode D5, a voltage stabilizing diode ZD2, a transistor Q5, a resistor R17, etc. based on the way as Figure 7 shown to form an IO port control circuit HBOT.

[0067] Among them, the triode Q3, the triode Q4, the diode D3, the resistor R14, and the resistor R18 control a path of the IO port HEAT of the common control component 15 of the first heating control circuit 106 and the second heating control circuit 107.

[0068] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , where the rectifier diode D1 is connected in series with the resistors R7, R8, and R9 at one end of the air fryer load heating tube, that is, one end of the first heating element 13. The control component 15 detects the voltage signal of the first detection circuit 104 through the IO port TCHK and judges whether the air fryer load heating tube is working according to the voltage information. When the control component 15 detects that there is a voltage signal at TCHK and detects that the IO port TTOP of the control component 15 connected to the first temperature acquisition circuit 102 of the upper cover is not disconnected, it can be determined that the air fryer load heating tube is not working and the upper cover is closed. Accordingly, the control component 15 can control the pressure cooker load heating plate, that is, the second heating element 14 can be turned on to work; among them, the control component 15 can output a high level through the IO port HBOT.

[0069] When the control component 15 detects that there is no voltage signal at TCHK and detects that the IO port TTOP of the control component 15 connected to the first temperature acquisition circuit 102 of the upper cover is not disconnected, it can be determined that the air fryer load heating tube is working. Accordingly, the control component 15 can control the pressure cooker load heating plate not to be turned on, and the control component 15 can output a low level through the IO port HBOT. Among them, the circuit of the first temperature acquisition circuit 102 can be led out from the upper cover of the cooking appliance 10 in the housing assembly 11 and connected to the control component 15 through an adjacent switch; among them, the switch will be connected only after the upper cover is closed. If the upper cover is not closed, the first temperature acquisition circuit 102 is not connected. Therefore, the control component 15 needs to detect whether the IO port TTOP of the control component 15 is disconnected.

[0070] Among them, the rectifier diode D2 is connected in series with the resistor R10, the resistor R11, and the resistor R12 at one end of the heating plate of the pressure cooker load, that is, one end of the second heating element 14. The control component 15 detects the voltage signal of the second detection circuit 104 through the IO port BCHK, and judges whether the heating tube of the pressure cooker load is working according to this voltage information. When the control component 15 detects that there is a voltage signal at BCHK and the IO port TTOP of the control component 15 connected to the first temperature acquisition circuit 102 of the upper cover is not disconnected, it can be determined that the heating plate of the pressure cooker load is not working and the upper cover is closed. Accordingly, the control component 15 can control the air fryer load heating tube to start working; among them, the control component 15 can output a low level through the IO port HTOP.

[0071] When the control component 15 detects that there is no voltage signal at BCHK and the IO port TTOP of the control component 15 connected to the first temperature acquisition circuit 102 of the upper cover is not disconnected, it can be determined that the heating plate of the pressure cooker load is working. Accordingly, the control component 15 can control the air fryer load heating tube not to start working, and the control component 15 can output a high level through the IO port HTOP.

[0072] In this embodiment, the cooking appliance 10 integrates the air fryer function and the pressure cooker function into one whole machine. Among them, the temperature sensor, heating tube, and fan corresponding to the air fryer function mode can be integrated in the upper cover part of the cooking appliance 10. The control component 15 can detect the temperature of the cooking cavity in real time in the air fryer function mode, and then control the turning on and off of the air fryer heating tube. Among them, the temperature sensor and heating plate corresponding to the pressure cooker function mode can be integrated in the chassis part of the cooking appliance 10. The control component 15 can detect the temperature of the cooking cavity in real time in the pressure cooker function mode, and then control the turning on and off of the pressure cooker heating plate.

[0073] Among them, TTOP can be the IO port of the first temperature acquisition circuit 102 (such as the temperature sensor NTC circuit) used by the control component 15 to detect the air fryer function temperature. At the same time, the control component 15 can also judge whether the upper cover of the cooking appliance 10 is closed by detecting the voltage signal of TTOP. Among them, TBOT can be the IO port of the second temperature acquisition circuit 103 (such as the thermocouple temperature sensor circuit) used by the control component 15 to detect the pressure cooker function temperature. At the same time, the control component 15 can also judge whether there is an inner pot in the cooking appliance 10 by detecting the voltage signal of TBOT.

[0074] Among them, the second temperature acquisition circuit 103 can connect a switch in parallel in the circuit connected to the control component 15. If the inner pot is pressed down in the cooking appliance 10, the switch is disconnected, and the thermocouple temperature sensor corresponding to the second temperature acquisition circuit 103 is not short-circuited; if there is no inner pot pressed down in the cooking appliance 10, the switch is in a closed state, and the thermocouple temperature sensor corresponding to the second temperature acquisition circuit 103 is short-circuited. Therefore, the control component 15 can determine whether there is an inner pot in the cooking appliance 10 by detecting whether the thermocouple temperature sensor is working.

[0075] Among them, TTOP can also be understood as the first temperature acquisition circuit, TBOT can be understood as the second temperature acquisition circuit, TCHK can be understood as the circuit for detecting the upper cover air fryer heating tube circuit, and BCHK can be understood as the circuit for detecting the bottom pressure cooker heating plate circuit. Correspondingly, before determining the target cooking mode to control the load to work, the cooking appliance 10 can perform self-check through the TTOP circuit, TBOT circuit, TCHK circuit, and BCHK circuit to ensure that the cooking appliance 10 can work normally safely and reliably.

[0076] Exemplarily, BCHK (bottom heating plate detection) --- the relay is not attracted, there is no level signal; after being attracted, there is a level signal; TCHK (upper cover heating tube detection) --- the relay is not attracted, there is a level signal; after being attracted, there is no level signal (the air fryer lid is closed); TCHK (upper cover heating tube detection) --- there is no level signal (the air fryer lid is not closed). Correspondingly. The process of the cooking appliance 10 performing self-check can include detecting whether the temperature sensor NTC of the TTOP circuit is open. If it is open, it can be determined that the cooking appliance 10 has no upper cover; if there is a resistance value, it can be determined that the cooking appliance 10 enters the air fry function mode. Correspondingly, the cooking appliance 10 can detect whether the states of the BCHK circuit and the TCHK circuit meet the requirements. If they do not meet the requirements, the control component 15 can generate an error prompt.

[0077] Among them, if it is determined that the cooking appliance 10 enters a non-air fry function mode, the BCHK circuit can be detected. If both BCHK and TCHK are detected, it can be detected whether the NTC of TBOT is open. When TBOT is open, the control component 15 can generate a prompt of no inner pot. If TBOT does not perform the no-inner-pot detection, it can be detected whether TTOP is short-circuited. If it is short-circuited, the control component 15 can generate a prompt of no pot.

[0078] Among them, if the cooking appliance 10 determines through self-check that each circuit module of the cooking appliance 10 operates normally and meets the requirements of normal working conditions, it can enter the corresponding target cooking mode to cook food.

[0079] In some embodiments, the control component 15 may execute the current cooking process after receiving a cooking instruction. During the cooking process, the control component 15 may determine the target heating element corresponding to the cooking mode as the target heating part when the cooking appliance 10 is in the cooking mode, and determine the target cooking temperature and the target cooking duration corresponding to the cooking mode. Then, based on the target cooking temperature and the target cooking duration, the control component 15 may control the heating parameters of the target heating element. Thus, by controlling the heating elements corresponding to different cooking modes when the cooking appliance 10 is in different cooking modes, the cooking performance of the cooking appliance 10 is improved while ensuring the cooking safety.

[0080] Please refer to Figure 8 , Figure 8 which shows a schematic flowchart of a cooking method provided by an embodiment of the present application. This cooking method controls the heating elements corresponding to different cooking modes when the cooking appliance is in different cooking modes, improving the cooking performance of the cooking appliance while ensuring the cooking safety. In a specific embodiment, this cooking method may be applied to a cooking device 200 as shown in Figure 12 and a cooking appliance 10 configured with the cooking device 200 ( Figure 13 ). Hereinafter, taking the cooking appliance as an example, the specific process of this embodiment will be described. Of course, it can be understood that the cooking appliance to which this embodiment is applied may include an air fryer, an oven, a microwave oven, etc., which are not limited herein. Next, the process shown in Figure 8 will be elaborated in detail. The cooking method may specifically include the following steps:

[0081] Step S110: When it is determined that the cooking appliance is in the first cooking mode, control the first heating element to work and control the second heating element not to work.

[0082] In some embodiments, the cooking appliance may include working modes such as a cleaning mode, a cooking mode, a warming mode, a standby mode, etc.; among them, the cooking mode may include various cooking methods, such as an air-frying mode, a pressure cooker mode, etc., which are not limited herein. Among them, in the cooking mode, the cooking appliance may cook the food placed in the cooking appliance; in the standby mode, each component included in the cooking appliance may be in a standby state. The cooking appliance may receive a control instruction input by the 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 the user in the standby mode and cook the food placed in the cooking appliance in response to the first cooking instruction.

[0083] In some embodiments, the cooking appliance can receive a first cooking instruction input by the user, wherein the first cooking instruction can carry a cooking method. Correspondingly, when receiving the first cooking instruction, the cooking appliance can determine that it needs to control the cooking appliance to enter the cooking mode. Further, the cooking appliance can parse the first cooking instruction to obtain the cooking method carried by the first cooking instruction, and control the cooking appliance to cook food based on the cooking method.

[0084] Wherein, the cooking appliance can include a first cooking mode and a second cooking mode. Among them, the cooking method corresponding to the first cooking mode is the air fry mode, and the cooking method corresponding to the second cooking mode is the pressure mode.

[0085] Correspondingly, after the cooking appliance determines the cooking method based on the first cooking instruction, it can determine the cooking mode corresponding to the cooking method. Among them, if it is determined that the cooking method is the air fry mode, the cooking appliance can be controlled to enter the first cooking mode. Further, in the case of determining that the cooking appliance is in the first cooking mode, the first heating element included in the cooking appliance can be controlled to work and the second heating element included in the cooking appliance can be controlled not to work.

[0086] As an implementable way, the cooking appliance can receive a second cooking instruction input by the user, wherein the second cooking instruction can carry a cooking duration and a cooking temperature. Correspondingly, after obtaining the second cooking instruction, the cooking appliance can parse the second cooking instruction to obtain the cooking duration and the cooking temperature, and in the case of determining that the cooking appliance is in the first cooking mode, control the first heating element to work and the second heating element not to work according to the cooking duration and the cooking temperature.

[0087] As another implementable way, the cooking appliance can be pre-set with a fixed cooking duration and cooking temperature corresponding to the first cooking mode. Wherein, the cooking appliance can receive a third cooking instruction input by the user, and the third cooking instruction may not carry a cooking duration and a cooking temperature; correspondingly, after obtaining the third cooking instruction, the cooking appliance can obtain the pre-set fixed cooking duration and cooking temperature corresponding to the first cooking mode, and in the case of determining that the cooking appliance is in the first cooking mode, control the first heating element to work and the second heating element not to work according to the cooking duration and the cooking temperature.

[0088] In some embodiments, the cooking appliance may further include a control panel. The cooking appliance can obtain the control instructions input by the user by detecting the pressing state of the control panel, and can control the load of the cooking appliance to enter the working state in response to the control instructions. Among them, when the cooking appliance determines that it is in the first cooking mode, it can control the corresponding function indicator light to turn on. Among them, the cooking appliance may further include a display screen. During the process of controlling the first heating element to work and the second heating element not to work according to the cooking duration and cooking temperature, the cooking appliance can display a cooking countdown of the cooking duration on the display screen.

[0089] Step S120: When it is determined that the cooking appliance is in the second cooking mode, control the second heating element to work and control the first heating element not to work.

[0090] In this embodiment, the cooking appliance may include a first cooking mode and a second cooking mode. Among them, the cooking method corresponding to the first cooking mode is the air fry mode, and the cooking method corresponding to the second cooking mode is the pressure mode.

[0091] Correspondingly, if the cooking appliance determines the cooking method based on the first cooking instruction, it can determine the cooking mode corresponding to the cooking method. Among them, if it is determined that the cooking method is the pressure mode, the cooking appliance can be controlled to enter the second cooking mode. Further, when it is determined that the cooking appliance is in the second cooking mode, the cooking appliance can be controlled to make the second heating element work and the first heating element included in the cooking appliance not work.

[0092] As an implementable method, the cooking appliance can receive a fourth cooking instruction input by the user. Among them, the fourth cooking instruction may carry the cooking duration and the cooking temperature. Correspondingly, after obtaining the fourth cooking instruction, the cooking appliance can parse the fourth cooking instruction to obtain the cooking duration and the cooking temperature, and when it is determined that the cooking appliance is in the second cooking mode, control the second heating element to work and control the first heating element not to work according to the cooking duration and the cooking temperature.

[0093] As another implementable method, the cooking appliance may be pre-set with a fixed cooking duration and cooking temperature corresponding to the second cooking mode. Among them, the cooking appliance can receive a fifth cooking instruction input by the user. Among them, the fifth cooking instruction may not carry the cooking duration and the cooking temperature; correspondingly, after obtaining the fifth cooking instruction, the cooking appliance can obtain the pre-set fixed cooking duration and cooking temperature corresponding to the second cooking mode, and when it is determined that the cooking appliance is in the second cooking mode, control the second heating element to work and control the first heating element not to work according to the cooking duration and the cooking temperature.

[0094] Among them, the cooking appliance can control the corresponding function indicator light to turn on when it is determined that the cooking appliance is in the second cooking mode. Among them, the cooking appliance can also include a display screen. During the process of controlling the second heating element to work and controlling the first heating element not to work according to the cooking duration and cooking temperature, the cooking appliance can display a cooking countdown of the cooking duration on the display screen.

[0095] In some embodiments, before entering the cooking mode, the cooking appliance can perform self-checks on the working states of load circuit modules such as the presence or absence of an inner pot, the state of the upper cover and the first heating element, and the state of the bottom second heating element, and can determine the target cooking mode (e.g., the first cooking mode or the second cooking mode) in which the cooking appliance is located according to the self-check result. Correspondingly, the cooking appliance can control the first heating element to work and control the second heating element not to work when it is determined that the cooking appliance is in the first cooking mode; or, when it is determined that the cooking appliance is in the second cooking mode, control the first heating element to work and control the second heating element not to work.

[0096] In some embodiments, the cooking appliance can also detect the temperature of the cooking cavity in real time after starting to work, and control the heating parameters of the first heating element and the second heating element according to the temperature in combination with the cooking duration and cooking temperature in the cooking mode in which the cooking appliance is located.

[0097] It can be understood that in this embodiment, on the basis of a cooking appliance that combines the air fryer function and the pressure cooker function in one whole machine, through a cooking method that combines air frying and pressure cooking provided by the present application, the thermal system management of integrating the air fryer function and the pressure cooker function in one whole machine is realized through the heating control circuit that combines the air fryer and the pressure cooker in the cooking appliance. Among them, the heating control circuit that combines the air fryer and the pressure cooker includes the heating control circuit of the air fryer and the heating load control circuit of the pressure cooker, and the two heating load control circuits of the air fryer and pressure functions are designed not to be turned on simultaneously, realizing the integration of the functions of the cooking appliance under the condition of optimal cost, the temperature rise of the whole machine meeting the requirements of the safety regulations test, and the derating of the overload current of the power cord, improving the cooking reliability of the cooking appliance and also improving the cooking safety of the cooking appliance.

[0098] The cooking method provided by an embodiment of the present application controls the first heating element to work and controls the second heating element not to work when it is determined that the cooking appliance is in the first cooking mode; or controls the second heating element to work and controls the first heating element not to work when it is determined that the cooking appliance is in the second cooking mode. Furthermore, by controlling the heating element corresponding to the cooking mode when the cooking appliance is in different cooking modes, the cooking performance of the cooking appliance is improved while ensuring the cooking safety.

[0099] Please refer to Figure 9 , Figure 9 which shows a schematic flowchart of a cooking method provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance. Below, a detailed description will be given for Figure 9 the process shown, and the cooking method may specifically include the following steps:

[0100] Step S210: Determine a target cooking mode in response to a target instruction, and determine the heating object corresponding to the target cooking mode as a target heating element, where the target cooking mode includes the first cooking mode or the second cooking mode, the heating object corresponding to the first cooking mode is the first heating element, and the heating object corresponding to the second cooking mode is the second heating element.

[0101] In some embodiments, the cooking appliance may receive a target instruction input by a user. Correspondingly, the cooking appliance may determine a target cooking mode in response to the target instruction, and may determine the heating object corresponding to the target cooking mode as a target heating element. Among them, the target cooking mode may be the first cooking mode or the second cooking mode; among them, the heating object corresponding to the first cooking mode is the first heating element included in the cooking appliance, and the heating object corresponding to the second cooking mode is the second heating element included in the cooking appliance.

[0102] In some embodiments, the target instruction may carry a target cooking duration and a target cooking temperature. Optionally, the cooking appliance may associate the target cooking duration and the target cooking temperature with the target cooking mode, and perform subsequent cooking operations.

[0103] Step S220: Control the heating parameters of the target heating element according to the target cooking mode.

[0104] In some embodiments, after the cooking appliance determines the target cooking mode and the target heating element, it may control the heating parameters of the target heating element according to the target cooking mode. Among them, the heating parameters may include heating power, heating time, etc., which are not limited herein.

[0105] In some embodiments, the process of the cooking appliance controlling the heating parameters of the target heating element according to the target cooking mode may include determining a target cooking duration and a target cooking temperature according to the target cooking mode, and determining a target temperature acquisition circuit from the first temperature acquisition circuit and the second temperature acquisition circuit included in the cooking appliance according to the target cooking mode, and controlling the heating parameters of the target heating element according to the target cooking temperature, the target cooking duration, and the temperature acquired by the target temperature acquisition circuit.

[0106] Optionally, the target temperature acquisition circuit determined from the first temperature acquisition circuit and the second temperature acquisition circuit included in the cooking appliance according to the target cooking mode may include the first temperature acquisition circuit, the second temperature acquisition circuit, or both the first temperature acquisition circuit and the second temperature acquisition circuit, which is not limited herein. Exemplarily, when the target cooking mode is the first cooking mode, the corresponding target temperature acquisition circuit may be the first temperature acquisition circuit; when the target cooking mode is the second cooking mode, the corresponding target temperature acquisition circuit may be the second temperature acquisition circuit.

[0107] Among them, the process of controlling the heating parameter of the target heating element according to the target cooking temperature, the target cooking duration, and the temperature acquired by the target temperature acquisition circuit may include, within the target cooking duration, controlling the target heating element to continuously heat based on the maximum power, acquiring the temperature acquired by the target temperature acquisition circuit as the first temperature, and controlling the heating parameter of the target heating element according to the first offset temperature value between the first temperature and the target cooking temperature.

[0108] Among them, if the target temperature acquisition circuit is the first temperature acquisition circuit, the cooking appliance may acquire the temperature acquired by the first temperature acquisition circuit within the target cooking duration as the first temperature; if the target temperature acquisition circuit is the second temperature acquisition circuit, the cooking appliance may acquire the temperature acquired by the second temperature acquisition circuit within the target cooking duration as the first temperature; if the target temperature acquisition circuit is both the first temperature acquisition circuit and the second temperature acquisition circuit, the cooking appliance may acquire, within the target cooking duration, the average value, maximum value, minimum value, or other temperature values of the temperature of the first temperature acquisition circuit and the temperature acquired by the second temperature acquisition circuit as the first temperature.

[0109] Among them, after the cooking appliance obtains the first temperature, it may obtain the first offset temperature value between the first temperature and the target cooking temperature according to the first temperature and the target cooking temperature, where the first offset temperature value may be the difference between the first temperature and the target cooking temperature.

[0110] In some embodiments, after the cooking appliance obtains the first offset temperature value, it can control the heating parameters of the target heating element according to the first offset temperature value between the first temperature and the target cooking temperature. Among them, if the target heating element is the first heating element and the first offset temperature value is less than the first deviation value, the first heating element can be controlled to heat at the maximum power for the first preset duration at the first time interval, and the temperature collected by the target temperature acquisition circuit can be obtained as the second temperature; if the second offset temperature value between the second temperature and the target cooking temperature is less than the second deviation value, the first heating element can be controlled to stop heating, and the temperature collected by the target temperature acquisition circuit can be obtained as the third temperature; if the third offset temperature value between the third temperature and the target cooking temperature is greater than the third deviation value, the first heating element can be controlled to heat at the maximum power for the first preset duration at the first time interval.

[0111] Among them, the first deviation value, the second deviation value, and the third deviation value can be preset in the cooking appliance. The cooking appliance can also obtain them from the associated cloud or electronic device through wireless communication technologies (such as Bluetooth, WiFi, zigbee, etc.). The cooking appliance can also obtain them from the associated electronic device through a serial communication interface (such as a serial peripheral interface, etc.); among them, the first deviation value, the second deviation value, and the third deviation value can be set by the user independently or obtained from third-party experimental data, which is not limited here. Among them, the second deviation value can be less than the first deviation value, and the third deviation value can be greater than the second deviation value; for example, the first deviation value can be set to more than 15 °C, the second deviation value can be set to more than 1 °C, and the third deviation value can be set to more than 2 °C. Among them, the first deviation value can be understood as the initial offset temperature of the first temperature acquisition circuit; the second deviation value can be understood as the offset temperature value of the set temperature of the first temperature acquisition circuit; the third deviation value can be understood as the offset value of the working temperature recovery of the first temperature acquisition circuit.

[0112] Among them, the first time interval can be preset in the cooking appliance. The cooking appliance can also obtain the first time interval from the associated electronic device or cloud through wireless communication technologies. The first time interval can be set by the user independently or obtained from third-party experimental data, which is not limited here. For example, the first time interval is set to more than 5 seconds.

[0113] Among them, the first preset duration can be preset in the cooking appliance. The cooking appliance can also obtain the first preset duration from the associated electronic device or cloud through wireless communication technologies. The first preset duration can be set by the user independently or obtained from third-party experimental data, which is not limited here. For example, the first preset duration is more than 10 seconds, etc.

[0114] Exemplarily, after determining that the target heating element is the first heating element and the first offset temperature value is less than the first deviation value, the cooking appliance can control the first heating element to heat at intervals of (x1, y1) based on the maximum power, where x1 is used to represent the first time interval and y1 is used to represent the first preset duration. Herein, x1 can be understood as the interval time for heating to turn on and can be set to more than 5 seconds; y1 can be understood as the heating cycle and can be set to more than 10 seconds.

[0115] During the process of the cooking appliance controlling the target heating element to heat at intervals, it can obtain the temperature collected by the target temperature acquisition circuit as the second temperature, and can obtain the difference between the second temperature and the target cooking temperature as the second offset temperature value. Correspondingly, if the cooking appliance determines that the second offset temperature value is less than the second deviation value, it can control the target heating element to stop heating, and during the process of controlling the target heating element to stop heating, it can obtain the temperature collected by the target temperature acquisition circuit as the third temperature, and can obtain the difference between the third temperature and the target cooking temperature as the third offset temperature value.

[0116] If the cooking appliance determines that the third offset temperature value is greater than the third deviation value, it can control the target heating element to heat at the maximum power for the first preset duration at the first time interval, that is, control the target heating element to return to the interval heating stage until the countdown of the target cooking duration of the cooking appliance reaches 0, then end the cooking, and control the cooking appliance to return from the first cooking mode to the standby state.

[0117] In some embodiments, the process of the cooking appliance controlling the heating parameters of the target heating element according to the first offset temperature value between the first temperature and the target cooking temperature may include that if the target heating element is the second heating element and the first offset temperature value is less than the fourth deviation value, it can control the second heating element to heat at the maximum power for the second preset duration at the second time interval, and can obtain the temperature collected by the target temperature acquisition circuit as the fourth temperature; if the fourth offset temperature value between the fourth temperature and the target cooking temperature is less than the fifth deviation value, it can control the second heating element to stop heating, and obtain the temperature collected by the target temperature acquisition circuit as the fifth temperature; if the fifth offset temperature value between the fifth temperature and the target cooking temperature is greater than the sixth deviation value, it can control the second heating element to heat at the maximum power for the second preset duration at the second time interval.

[0118] Among them, a fourth deviation value, a fifth deviation value, and a sixth deviation value can be preset in the cooking appliance, or the cooking appliance can obtain them from an associated electronic device or the cloud through wireless communication technology. The cooking appliance can also obtain them from an associated electronic device through a serial communication interface. Among them, the fourth deviation value, the fifth deviation value, and the sixth deviation value can be set by the user independently or obtained through third-party experimental data, which is not limited herein. Among them, the fifth deviation value can be less than the fourth deviation value, and the sixth deviation value can be greater than the fifth deviation value.

[0119] Exemplarily, the fourth deviation value can be set to be above 15°C, the fifth deviation value can be set to be above 10°C, and the sixth deviation value can be set to be above 12°C. Among them, the fourth deviation value can be understood as the initial charging offset temperature of the second temperature acquisition circuit; the fifth deviation value can be understood as the offset temperature value of the set temperature of the second temperature acquisition circuit; the sixth deviation value can be understood as the offset value of the working temperature recovery of the second temperature acquisition circuit.

[0120] Among them, the second time interval can be preset in the cooking appliance, or the cooking appliance can obtain the second time interval from an associated electronic device or the cloud through wireless communication technology. The second time interval can be set by the user independently or obtained through third-party experimental data, which is not limited herein. For example, the second time interval is set to be above 5 seconds.

[0121] Among them, the second preset duration can be preset in the cooking appliance, or the cooking appliance can obtain the second preset duration 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 herein. Exemplarily, the second preset duration is above 10 seconds, etc.

[0122] Exemplarily, when the cooking appliance determines that the target heating element is the second heating element and the first offset temperature value is less than the fourth deviation value, it can control the second heating element to heat at intervals of (x2, y2) based on the maximum power, where x2 is used to represent the second time interval and y2 is used to represent the second preset duration. Among them, x2 can be understood as the interval time for heating to turn on and can be set to be above 5 seconds; y2 can be understood as the heating cycle and can be set to be above 10 seconds.

[0123] Among them, during the process of the cooking appliance controlling the second heating element to heat intermittently, the temperature collected by the target temperature acquisition circuit can be obtained as the fourth temperature, and the difference between the fourth temperature and the target cooking temperature can be obtained as the fourth offset temperature value. Correspondingly, if the cooking appliance determines that the fourth offset temperature value is less than the fifth deviation value, the second heating element can be controlled to stop heating, and during the process of controlling the second heating element to stop heating, the temperature collected by the target temperature acquisition circuit can be obtained as the fifth temperature, and the difference between the fifth temperature and the target cooking temperature can be obtained as the fifth offset temperature value.

[0124] Among them, if the cooking appliance determines that the fifth offset temperature value is greater than the sixth deviation value, the second heating element can be controlled to heat at the maximum power for the second preset duration according to the second time interval, that is, the second heating element is controlled to return to the intermittent heating stage until the countdown of the target cooking duration of the cooking appliance reaches 0, at which time the cooking ends, and the cooking appliance is controlled to return from the second cooking mode to the standby state.

[0125] Step S230: When it is determined that the cooking appliance is in the first cooking mode, control the hot air blower included in the cooking appliance to rotate continuously, control the first heating element to work, and control the second heating element not to work.

[0126] In some embodiments, the cooking appliance can control the hot air blower included in the cooking appliance to rotate continuously when it is determined that the cooking appliance is in the first cooking mode. Exemplarily, when it is determined that the cooking appliance is in the first cooking mode, and during the process of controlling the first heating element to heat at the maximum power and controlling the second heating element to stop heating, that is, the first charging stage, the hot air blower can be controlled to rotate at the medium or high speed to promote the hot air circulation in the cooking cavity, so that the heat can quickly flow to all parts of the frying bucket. Among them, when it is determined that the cooking appliance is in the first cooking mode, and during the process of controlling the first heating element to heat at the maximum power for the first preset duration according to the first time interval and controlling the second heating element to stop heating, that is, the intermittent heating stage, the hot air blower can be controlled to rotate at the medium or high speed. Among them, when it is determined that the cooking appliance is in the first cooking mode, and during the process of controlling the first heating element to stop heating and controlling the second heating element to stop heating, that is, the stop heating stage, the hot air blower can be controlled to rotate at a speed lower than that in the intermittent heating stage. For example, if the speed in the intermittent heating stage is high, the speed in the stop heating stage can be medium or low; if the speed in the intermittent heating stage is medium, the speed in the stop heating stage can be low.

[0127] In this embodiment, when the cooking appliance determines that it is in the first cooking mode, it can obtain the temperature collected by the first temperature acquisition circuit in real time and the temperature collected by the second temperature acquisition circuit. If the temperature collected by the first temperature acquisition circuit is greater than the first over-temperature protection temperature or the temperature collected by the second temperature acquisition circuit is greater than the second over-temperature protection temperature, the first heating element and the second heating element can be controlled to stop heating to perform over-high temperature protection processing. Correspondingly, when the cooking appliance obtains that the temperatures collected by the first temperature acquisition circuit and the second temperature acquisition circuit are both less than or equal to the first restart temperature, it can control the cooking appliance to re-enter the first cooking mode.

[0128] Among them, the first over-temperature protection temperature, the second over-temperature protection temperature, and the first restart temperature can be preset in the cooking appliance. Exemplarily, the first over-temperature protection temperature can be the NTC over-high temperature protection temperature, which can be set above 200 °C; the second over-temperature protection temperature can be the thermocouple over-high temperature protection temperature, which can be set above 300 °C; the first restart temperature can be set below 105 °C.

[0129] Exemplarily, please refer to Figure 10 , which shows a schematic flowchart of a cooking method provided by an embodiment of the present application. Among them, the cooking appliance determines the target cooking mode in response to the target instruction. If it is determined that the target cooking mode is the first cooking mode (air fry cooking mode), the first heating element (upper heating tube) can be determined as the target heating element. The cooking appliance can obtain the target cooking temperature and the target cooking duration according to the target instruction. The cooking appliance can control the function indicator light corresponding to the air fry cooking mode to turn on and display the countdown of the target cooking duration. Correspondingly, the cooking appliance can detect whether there is an inner pot, the working state of the BCHK detection circuit (second detection circuit) corresponding to the second heating element (bottom infrared disk), and the working state of the TCHK detection circuit (first detection circuit) corresponding to the upper heating tube to obtain the self-check result, and can obtain the temperature collected by the first temperature acquisition circuit and / or the second temperature in real time to detect the temperature of the cooking cavity.

[0130] Among them, after the self-check of the cooking appliance is completed and the obtained self-check result meets the requirements of the air fry cooking mode, the cooking in the first charging stage can be carried out. The cooking appliance can control the upper heating tube to continuously heat based on the maximum power within the target cooking duration, control the hot air blower to rotate at full speed, control the infrared heating disk to stop heating, and obtain the temperature collected by the target temperature acquisition circuit (such as the first temperature acquisition circuit) as the first temperature, and obtain the first offset temperature value between the first temperature and the target cooking temperature.

[0131] Accordingly, if the cooking appliance determines that the target heating element is the first heating element and the first offset temperature value is less than the first deviation value, it can control the first heating element to heat for the first preset duration at the maximum power according to the first time interval, control the hot air blower to rotate at the medium or high speed, and obtain the temperature collected by the target temperature acquisition circuit as the second temperature. Accordingly, if the cooking appliance determines that the second offset temperature value between the second temperature and the target cooking temperature is less than the second deviation value, it can control the first heating element to stop heating, the second heating tube to stop heating, control the hot air blower to rotate based on the preset speed, and obtain the temperature collected by the target temperature acquisition circuit as the third temperature. Accordingly, if the cooking appliance determines that the third offset temperature value between the third temperature and the target cooking temperature is greater than the third deviation value, it can control the first heating element to return to the step of heating for the first preset duration at the maximum power according to the first time interval. Among them, the rotation at the preset speed can be set by the user independently.

[0132] Among them, the cooking appliance ends cooking when the countdown of the target cooking duration reaches 0 and returns to the standby state.

[0133] Among them, the cooking appliance can detect whether the temperature collected by the first temperature acquisition circuit is greater than the first over-temperature protection temperature or whether the temperature collected by the second temperature acquisition circuit is greater than the second over-temperature protection temperature throughout the cooking process. If so, it can control the cooking appliance to perform over-high temperature protection processing, that is, control all heating loads to stop until the cooking appliance detects that the temperatures collected by the first temperature acquisition circuit and the second temperature acquisition circuit cool down below the first restart temperature, and then it can control the cooking appliance to re-enter the first cooking mode.

[0134] Step S240: When it is determined that the cooking appliance is in the second cooking mode, control the hot air blower included in the cooking appliance to rotate during the process of the second heating element stopping heating, control the second heating element to work, and control the first heating element not to work.

[0135] In some embodiments, when it is determined that the cooking appliance is in the second cooking mode, the cooking appliance can control the hot air blower included in the cooking appliance to rotate during the process of the second heating element stopping heating. Exemplarily, when it is determined that the cooking appliance is in the second cooking mode, and the second heating element is controlled to generate heat based on the maximum power, during the process of controlling the first heating element to stop generating heat, that is, the first flush stage, the hot air blower can be controlled to stop rotating. Among them, when it is determined that the cooking appliance is in the second cooking mode, and the second heating element is controlled to generate heat based on the maximum power for a second preset duration at a second time interval, during the process of controlling the first heating element to stop generating heat, that is, the interval heating stage, the hot air blower can be controlled to stop rotating. Among them, when it is determined that the cooking appliance is in the second cooking mode, and the second heating element is controlled to stop generating heat, during the process of controlling the first heating element to stop generating heat, that is, the stop heating stage, the hot air blower can be controlled to rotate at a high, medium, or low speed.

[0136] In this embodiment, when it is determined that the cooking appliance is in the second cooking mode, the cooking appliance can obtain the temperature collected by the first temperature acquisition circuit and the temperature collected by the second temperature acquisition circuit in real time. Among them, if the temperature collected by the first temperature acquisition circuit is greater than the first over-temperature protection temperature or the temperature collected by the second temperature acquisition circuit is greater than the second over-temperature protection temperature, the first heating element and the second heating element can be controlled to stop generating heat to perform over-temperature protection processing. Correspondingly, when the cooking appliance obtains that the temperatures collected by the first temperature acquisition circuit and the second temperature acquisition circuit are both less than or equal to the second restart temperature, the cooking appliance can be controlled to re-enter the second cooking mode.

[0137] Among them, the second restart temperature can be preset in the cooking appliance. Exemplarily, the second restart temperature can be set to below 50°C.

[0138] Exemplarily, please refer to Figure 11 , which shows a schematic flowchart of a cooking method provided by an embodiment of the present application. Among them, the cooking appliance determines the target cooking mode in response to a target instruction. If it is determined that the target cooking mode is the second cooking mode (pressure cooking mode), the second heating element (bottom infrared heating plate) is determined as the target heating element; among them, the cooking appliance can obtain the target cooking temperature and the target cooking duration according to the target instruction. Among them, the cooking appliance can control the function indicator light corresponding to the pressure cooking mode to turn on and display a countdown for the target cooking duration. Correspondingly, the cooking appliance can detect whether there is an inner pot, the working state of the BCHK detection circuit (second detection circuit) corresponding to the second heating element (bottom infrared plate), the working state of the TCHK detection circuit (first detection circuit) corresponding to the upper heating tube to obtain a self-check result, and can obtain the temperature collected by the first temperature acquisition circuit and / or the second temperature in real time to detect the temperature of the cooking cavity.

[0139] Among them, after the self-check of the cooking appliance is completed and the obtained self-check result meets the requirements of the pressure cooking mode, cooking in the first brewing stage can be carried out. Among them, the cooking appliance can control the bottom infrared heating plate to continuously heat based on the maximum power within the target cooking duration, control the hot air blower to stop rotating, control the upper heating tube to stop heating, and obtain the temperature collected by the target temperature acquisition circuit (such as the second temperature acquisition circuit) as the first temperature, and obtain the first offset temperature value between the first temperature and the target cooking temperature.

[0140] Correspondingly, if the cooking appliance determines that the target heating element is the second heating element and the first offset temperature value is less than the fourth deviation value, it can control the second heating element to heat for a second preset duration at the maximum power at a second time interval, control the hot air blower to stop rotating, and obtain the temperature collected by the second temperature acquisition circuit as the fourth temperature. Correspondingly, if the cooking appliance determines that the fourth offset temperature value between the fourth temperature and the target cooking temperature is less than the fifth deviation value, it can control the second heating element to stop heating, the first heating element to stop heating, control the hot air blower to rotate at a preset gear, and obtain the temperature collected by the target temperature acquisition circuit as the fifth temperature. Correspondingly, if the cooking appliance determines that the fifth offset temperature value between the fifth temperature and the target cooking temperature is greater than the sixth deviation value, it can control the second heating element to return to heat for a second preset duration at the maximum power at a second time interval. Among them, the rotation at the preset gear can be set by the user independently.

[0141] Among them, the cooking appliance ends cooking when the countdown of the target cooking duration reaches 0 and returns to the standby state.

[0142] Among them, the cooking appliance can detect whether the temperature collected by the first temperature acquisition circuit is greater than the first over-temperature protection temperature or whether the temperature collected by the second temperature acquisition circuit is greater than the second over-temperature protection temperature throughout the cooking process. If so, it can control the cooking appliance to perform over-high temperature protection processing, control all heating loads to stop until the cooking appliance detects that the temperatures collected by the first temperature acquisition circuit and the second temperature acquisition circuit cool below the second restart temperature, then it can control the cooking appliance to re-enter the second cooking mode.

[0143] It can be understood that in this embodiment, based on a cooking appliance that combines the air fryer function and the pressure cooker function in one integrated unit, through a cooking method for integrating the air fryer and the pressure cooker provided by the present application, the thermal system management of integrating the air fryer function and the pressure cooker function on one integrated unit is achieved through the heating control circuit that combines the air fryer and the pressure cooker designed in the cooking appliance. During the cooking process, by controlling the rotation of the hot air blower to transfer the air inside and around the heat source, the heat dissipation performance of the whole machine is improved. Among them, the heating control circuit that combines the air fryer and the pressure cooker includes the heating control circuit of the air fryer and the heating load control circuit of the pressure cooker. The single-chip microcomputer can control the on and off of the two heating loads according to the temperature sensed by the temperature sensor, so that the two heating load control circuits of the air fryer and the pressure function cannot be turned on simultaneously. Under the condition of optimal cost, the temperature rise of the whole machine meeting the requirements of the safety regulations test, and the design of derating the over-current of the power cord, the functions of the cooking appliance are integrated, the cooking reliability of the cooking appliance is improved, and the cooking safety of the cooking appliance is also improved.
