[0024] In order to enable those skilled in the art of the present technology to better understand the solution 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 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 of 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.

[0025] With the development of science and technology, cooking appliances are becoming more and more diverse, and people's requirements for the practicality of cooking appliances are getting higher and higher. At present, most cooking appliances include a single cooking cavity. Using a single cooking cavity to cook food has the situation of single cooked food and long time consumption. Therefore, with the acceleration of people's life rhythm, cooking appliances have the problems of low practicality and low cooking performance.

[0026] Exemplarily, traditional air fryers all use a single cavity for baking and air frying. Sometimes, when users want to bake different ingredients, they need to bake the ingredients in turns, which makes the cooking time of users relatively long and cannot meet the fast-paced life of users. Therefore, in the related art, there are problems of low cooking performance and practicability in cooking appliances.

[0027] In view of the above problems, through long-term research, the inventors found and proposed a cooking appliance, a heating method, and a device provided by an embodiment of the present application. By simultaneously controlling the working parameters of at least two heating devices to cook the food in at least two cooking cavities, the practicability and cooking performance of the cooking appliance are improved. Among them, the specific heating method will be described in detail in the subsequent embodiments.

[0028] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of a cooking appliance provided by an embodiment of the present application. Figure 2 which 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, at least two frying barrels 12, at least two heating devices 13, and a control assembly 14.

[0029] Among them, the housing assembly 11 is provided with at least two receiving cavities. Each frying barrel 12 (such as frying barrel 1, frying barrel 2, etc.) is movably arranged in each receiving cavity, corresponding to each receiving cavity one by one. Each frying barrel 12 includes a bottom wall and a peripheral wall. The peripheral wall of each frying barrel 12 is circumferentially connected to the periphery of the bottom wall of each frying barrel to jointly form a cooking cavity for each frying barrel 12 to accommodate food. Among them, each heating device 13 (such as heating device 1, heating device 2, etc.) is arranged in the housing assembly 11, corresponding to each frying barrel 12 one by one (such as heating device 1 corresponding to frying barrel 1, heating device 2 corresponding to frying barrel 2), and is used to heat the cooking cavity corresponding to each frying barrel 12. Among them, the control assembly 14 is respectively connected to at least two heating devices 13, and is used to obtain the cooking duration and cooking temperature corresponding to each cooking cavity, and control the working parameters of at least two heating devices 13 according to the cooking duration and cooking temperature corresponding to each cooking cavity, such as heating time, heating power, etc.

[0030] Among them, the cooking appliance 10 may have a cooking function. Among them, the cooking appliance 10 may generate hot air through each heating device 13, 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 embodiment of the present application, the cooking appliance 10 may be an air fryer with a cooking function, such as Figure 2 shown.

[0031] Among them, according to Figure 2It can be seen that the outer shell assembly 11 plays a supporting role. The outer shell assembly 11 may include a bottom cover, side walls, 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 at least two accommodating cavities, and each accommodating cavity is used to accommodate a frying barrel 12. The side wall is formed with an opening for placing each frying barrel 12 in each accommodating cavity. Among them, at least two accommodating cavities can be designed as at least two cavities in a left-right or up-down manner.

[0032] Each frying barrel 12 can be movably arranged in each accommodating cavity. When each frying barrel 12 is arranged in each accommodating cavity, a handle is provided on the surface of each frying barrel 12 exposed from each accommodating cavity for the user to grasp. Each 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.

[0033] In some embodiments, a control panel is provided on the outer surface of the side wall of the outer shell assembly 11 or on 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, and the like.

[0034] In some embodiments, each heating device 13 is correspondingly arranged with each cooking cavity and is fixedly arranged in the outer shell assembly 11 through a fixing structure. Each heating device 13 is used to heat the cooking cavity corresponding to each frying barrel 12 so that the gas in each cooking cavity is heated, and the ingredients placed in each cooking cavity are cooked. It should be noted that the fixing structures for fixing each heating device 13 may be the same or different.

[0035] Please refer to Figure 3 , in some embodiments, each heating device 13 may include a heating element 131 and a control circuit 132. Among them, each control circuit 132 can be respectively connected to the control component 14 and the heating element 131 corresponding to each control circuit 132, and can be used to receive the target signal output by the control component 14 and control the heating time of the heating element 131 corresponding to each control circuit 132 according to the target signal.

[0036] Among them, the heating element 131 is used to realize the cooking function of the cooking appliance 10. Optionally, each heating element 131 may include a heating tube, a heating plate, etc. The models of the heating elements included in each heating device 13 may be the same or different; the number of heating elements corresponding to each heating device 13 may be one or more, which is not limited herein.

[0037] Exemplarily, please refer to again Figure 2, the heating device 13 may include a heating device 1 and a heating device 2; wherein, the heating device 1 includes a heating element 1, and the heating device 2 includes a heating element 2. Among them, the heating element 1 may include a heating tube with a model of AC voltage 220V, 50Hz, and 1500W; the heating element 2 may include a heating tube with a model of AC voltage 220V, 50Hz, and 1500W.

[0038] Among them, the control circuit 132 included in each heating device 13 may be composed of multiple circuit elements. For example, it may be composed of one or more resistance elements, one or more capacitance elements, one or more electronic switches, one or more diodes and other elements.

[0039] Among them, each control circuit 132 may include a target electronic switch. Among them, each target electronic switch may include an NPN-type triode. Among them, the base of each target electronic switch is connected to the control component 14, the emitter of each target electronic switch is grounded, and the collector of each target electronic switch is connected to other control circuits. The control component 14 may be used to turn on the target electronic switch according to the target signal to control the heating element corresponding to other control circuits to stop heating.

[0040] Exemplarily, please refer to Figure 4 and Figure 2 , wherein, Figure 4 shows the circuit diagram of the control circuit provided by an embodiment of the present application. Among them, at least two heating devices 13 include a first heating device and a second heating device. Among them, the first heating device includes a heating element 1 and a control circuit 1 (not shown in the figure). Among them, the cooking cavity corresponding to the first heating device may correspond to the right cavity of the heating double-chamber air fryer as shown in Figure 2 ; among them, the second heating device includes a heating element 2 and a control circuit 2 (not shown in the figure). Among them, the cooking cavity corresponding to the second heating device may correspond to the left cavity of the heating double-chamber air fryer as shown in Figure 2 .

[0041] Among them, the control circuit 1 is respectively connected to the heating element 1 and the control component 14, and is used to receive the first target signal output by the control component 14 and control the heating time of the heating element 1 according to the first target signal; the control circuit 2 is respectively connected to the heating element 2 and the control component 14, and is used to receive the second target signal output by the control component 14 and control the heating time of the heating element 2 according to the second target signal.

[0042] Among them, the control circuit 1 may be composed of a relay REL1, a triode Q1, a triode Q2, a resistor R1, a resistor R2, a diode D1, a zener diode DZ1 and a capacitor C1 based on Figure 4It is composed by connecting in the manner shown. Among them, the control circuit of relay REL1 can be controlled by the output signals of two IO ports of control component 14; among them, the PWM port of one control component 14 can output an abnormal signal to control the 12V terminal of the input power supply of relay REL1, corresponding to Figure 4 the REL port of control component 14 in the middle; among them, the other path can output high and low level signals by the IO port (REL2-H) of control component 14 to control the suction end of the coil of relay REL1.

[0043] Among them, control circuit 2 can be composed by connecting relay REL2, triode Q3, triode Q4, triode Q5, triode Q6, resistor R3, resistor R4, resistor R5, resistor R6, resistor R7, diode D2, diode D3, diode D4, diode D5, zener diode DZ2, electrolytic capacitor C2, monolithic capacitor C3, capacitor C4 based on as Figure 4 shown in the manner. Among them, the control circuit of relay REL2 can be controlled by the output signals of two IO ports of control component 14; among them, the PWM port of one control component 14 can output an abnormal signal to control the 12V terminal of the input power supply of relay REL2, corresponding to Figure 4 the REL port of control component 14 in the middle; among them, the other path can output high and low level signals by the IO port (REL1-H) of control component 14 to control the suction end of the coil of relay REL2. One end of relay REL1 and relay REL2 can be connected to power bus ACL1.

[0044] Among them, when the PWM port of control component 14 outputs an abnormal signal, such as a square wave signal, this square wave signal can charge electrolytic capacitor C2 after passing through monolithic capacitor C3 and diode D4. When the base voltage of triode Q4 is reached, triode Q4 conducts, and the base voltage of triode Q3 is pulled down, thereby making PNP triode Q5 conduct, and the 12V power supply of relay REL2 is turned on. Diode D2 can be used as a clamping diode so that the maximum voltage borne by the triode does not exceed 12V to protect the circuit.

[0045] Among them, when the IO port of REL1-H of the control component 14 outputs a high-level signal, the triode Q5 conducts, the relay REL2 switch conducts, and the heating element 2 of the left chamber load starts to heat up. At the same time, the triode Q6 can be used as the target switch in the control circuit 2, which can include an NPN transistor, and its collector is connected to the base of the triode Q1 in the relay control circuit of the heating subsystem of the right cavity. When the relay control circuit for controlling the heating tube in the left chamber outputs a high-level signal from the IO port of REL1-H of the control component 14, the triode Q5 conducts, and the NPN triode Q6 conducts simultaneously, pulling down the base level of the triode Q1 in the relay control circuit of the heating subsystem of the right cavity, disconnecting the heating of the heating tube of the right chamber load, and thus ensuring that when the heating subsystem of the left cavity works, the heating subsystem of the right cavity is locked and cannot work.

[0046] Among them, the circuit for controlling the 12V input power terminal of the relay REL2 and the circuit for controlling the 12V input power terminal of the relay REL1 can share the control circuit of a single-chip microcomputer PWM port (REL terminal) of the control component 14, so as to reduce the IO port resources and some circuits of the control component 14, reduce the cost of circuit design, and improve the practicability of the cooking appliance 10.

[0047] Among them, when the IO port of REL2-H of the control component 14 outputs a high-level signal, the triode Q1 conducts, the relay REL1 switch conducts, and the heating tube of the right chamber load starts to heat up. At the same time, the triode Q2 can be understood as the target switch in the control circuit 1, which can include an NPN transistor, and its collector is connected to the base of the triode Q5 in the relay control circuit of the heating subsystem of the left cavity. When the relay control circuit for controlling the heating tube in the right chamber outputs a high-level signal from the single-chip microcomputer IO port, the triode Q5 conducts, and the NPN triode Q2 also conducts simultaneously, pulling down the base level of the triode Q1 in the relay control circuit of the heating subsystem of the left cavity, disconnecting the heating of the heating tube of the left chamber load, and thus ensuring that when the heating subsystem of the right cavity works, the heating subsystem of the left cavity is locked and cannot work.

[0048] Among them, the triode Q6 can be used as the target electronic switch included in the control circuit 2, including an NPN transistor, and the triode Q2 can be used as the target electronic switch included in the control circuit 1, including an NPN transistor. They can be important components for interlocking the two heating subsystems of the left and right or upper and lower cavities from the hardware circuit aspect in the control circuit of the double-chamber air fryer heating system.

[0049] It can be understood that, due to the large heating load power of the air fryer, if it is required to realize the simultaneous operation of the heating loads of two cavities, this not only needs to meet the derating design requirements of the total load power and current that the power cord of the whole machine can withstand, but also needs to meet the compliance test requirements and prevent adverse phenomena such as the power cord getting hot and catching fire. Therefore, when the total power of the two heating loads of the double-cavity air fryer is greater than the rated power of the power cord of the whole machine, the control circuit of the heating system of the double-cavity air fryer needs to be designed in the hardware circuit to enable the control circuit of the heating subsystem in one cavity to work while the control circuit of the heating subsystem in the other cavity stops working, so that the two heating subsystems can achieve an interlocking function in the hardware circuit and the two heating subsystems will not work simultaneously.

[0050] In this embodiment, the control circuit of the heating system of the double-cavity air fryer is as Figure 4 shown. The working principle of this control circuit is that the control circuit of each cavity heating subsystem is controlled by the control component 14 using dual-channel IO ports. One IO port of the control component 14 outputs high and low level signals for control, and the other PWM port of the control component 14 outputs abnormal signals for control. Among them, the double-cavity air fryer can adopt a heating system control circuit designed with left and right cavities or upper and lower cavities. The control component 14 controls the output signals of the heating system circuits in the two cavities respectively, so that the two cavities of the double-cavity air fryer can work simultaneously. Furthermore, although the heating system of the double-cavity air fryer performs interlocking control on the load heating system in hardware, in fact, it can be controlled from the software control method to enable the two cavities to cook food simultaneously, so that the double-cavity air fryer can become a kitchen appliance category with excellent value for money, improving the practicality and cooking performance of the cooking appliance 10.

[0051] Please refer to Figure 5 , in some embodiments, the cooking appliance 10 may include at least two temperature sensing circuits 15. Among them, each temperature sensing circuit 15 may be arranged in the housing assembly 11 and corresponds to the cooking cavity formed with each frying barrel 12, and is used to collect the temperature of the cooking cavity corresponding to each frying barrel 12.

For example, the NTC detection circuit is composed of an NTC sensor, one or more resistor elements, one or more capacitor elements, one or more comparators and other elements, which is not limited herein.

Among them, each hot air blower 101 can be arranged in the housing assembly 11, corresponding to each frying bucket 12 one by one, and arranged on the side of the corresponding heating element relative to the cooking cavity away from the cooking cavity. Among them, each hot air blower 101 can be arranged at an interval from the corresponding heating element, and the hot air blower 101 is also fixedly arranged in the housing assembly 11 through a fixing structure. In some embodiments, the hot air blower 101 can be used to cause the high-temperature gas generated by the heating of the corresponding heating element to circulate convectively in the cooking cavity, so as to cook the food. It should be noted that the fixing structure for fixing the heating element and the fixing structure for fixing the hot air blower 101 can be the same or different.

[0057] When the cooking appliance 10 includes at least two hot air blowers 101, the control component 14 is connected to each hot air blower 101, for controlling the working parameters of each hot air blower 101, such as the rotation speed, rotation duration, etc. of the hot air blower 101. Exemplarily, the at least two hot air blowers 101 can include a hot air blower 1 and a hot air blower 2, among which, the hot air blower 1 and the hot air blower 2 can be fans with a model of AC220V, 50Hz, 25W.

[0058] Please refer to again Figure 2, in some embodiments, the cooking appliance 10 may further include at least two furnace lamps 102. Among them, each furnace lamp 102 may be disposed in the housing assembly 11, corresponding to each frying barrel 12 one by one, and disposed above the cooking cavity; among them, each furnace lamp 102 is also fixedly disposed in the housing assembly 11 through a fixing structure. In some embodiments, the furnace lamp 102 may be used for illumination so that the user can view the food in the cooking cavity. It should be noted that the fixing structure for fixing the heating element and the fixing structure for fixing the furnace lamp 102 may be the same or different.

[0059] When the cooking appliance 10 includes at least two furnace lamps 102, the control component 14 is connected to each furnace lamp 102 for controlling the working state of each furnace lamp 102, such as turning on or off. Exemplarily, the at least two furnace lamps 102 include furnace lamp 1 and furnace lamp 2, where furnace lamp 1 and furnace lamp 2 may be lamps with a model of AC220V, 50Hz, and 25W.

[0060] In some embodiments, the control component 14 is also connected to the control panel on the housing assembly 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 14. The control component 14 controls the cooking appliance 10 based on this electrical signal. Optionally, the control component 14 is a Micro Controller Unit (MCU).

[0061] Exemplarily, please refer to Figure 6 , which shows a schematic structural diagram of the function modules of the cooking appliance provided in an embodiment of the present application. Among them, the cooking appliance 10 includes a double-chamber air fryer, which is mainly composed of a main control board 16 and a display board 17.

In a specific embodiment, this heating method can be applied to a heating device 200 as shown in Figure 10 and a cooking appliance 10 configured with the heating device 200 ( Figure 11 ). The following will take the cooking appliance as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the cooking appliance to which this embodiment is applied can include an air fryer, an oven, a microwave oven, etc., which are not limited herein. The following will elaborate in detail on the Figure 7 shown process. The heating method can specifically include the following steps:

[0068] Step S110: Obtain the cooking duration and cooking temperature corresponding to each of the cooking cavities.

[0069] In some embodiments, the cooking appliance can include working modes such as a cleaning mode, a cooking mode, a warming mode, a standby mode, etc. Among them, in the cooking mode, the cooking appliance can cook the food placed in the cooking appliance; in the standby mode, each component included in the cooking appliance can be in a standby state, and the cooking appliance can receive a control instruction input by the user and switch the working mode of the cooking appliance based on this control instruction. Exemplarily, the cooking appliance can receive a first cooking instruction input by the user in the standby mode and respond to this first cooking instruction to cook the food placed in the cooking appliance.

[0070] In this embodiment, the cooking appliance can include at least two cooking cavities. Among them, the user can place the same ingredients in each cooking cavity or different ingredients in each cooking cavity, which is not limited herein.

[0071] As an implementable manner, the cooking appliance can receive a first cooking instruction input by the user. Among them, the first cooking instruction can carry the cooking duration and cooking temperature. Correspondingly, the cooking appliance can determine that it is necessary to control the cooking appliance to enter the cooking mode when receiving this first cooking instruction. Further, the cooking appliance can parse this first cooking instruction to obtain the cooking duration and cooking temperature carried by the first cooking instruction, and can use this cooking duration and this cooking temperature as the cooking duration and cooking temperature corresponding to each cooking cavity included in the cooking appliance.

[0072] Among them, the cooking appliance can detect whether there is an inner pot for each cooking cavity based on the zero-crossing circuit of the microswitch, and heat each cooking cavity according to the inner pot detection result. Exemplarily, if the cooking appliance detects that the voltage signal output by the zero-crossing circuit of the microswitch corresponding to the cooking cavity is at a low level, it can be determined that there is an inner pot in the cooking cavity, and the heating device corresponding to the cooking cavity can be controlled to generate heat for cooking food; if the cooking appliance detects that the voltage signal output by the zero-crossing circuit of the microswitch corresponding to the cooking cavity is at a high level, it can be determined that there is no inner pot in the cooking cavity, and the heating device corresponding to the cooking cavity can be controlled to stop working.

[0073] Among them, the first cooking instruction may include multiple cooking temperatures and multiple cooking durations, or may include one cooking temperature and one cooking duration, which is not limited here; among them, the cooking temperature may correspond one-to-one with the cooking duration, and each cooking temperature and the corresponding cooking duration may correspond to one cooking cavity, or may correspond to at least two cooking cavities, which is not limited here.

[0074] As another implementable manner, the cooking temperatures and cooking durations corresponding to the cooking cavities of the cooking appliance may be fixed. The cooking appliance may receive a second cooking instruction input by the user, where the second heat preservation instruction does not carry the cooking temperature and the cooking duration. Correspondingly, the cooking appliance may determine that it is necessary to control the cooking appliance to enter the cooking mode when receiving the second cooking instruction. Further, the cooking appliance may control the heating devices corresponding to the cooking cavities to work based on the fixed cooking durations and fixed cooking temperatures corresponding to the cooking cavities.

[0075] Optionally, the cooking duration corresponding to each cooking cavity may be set independently by the user, or obtained through third-party experimental data, such as 1 minute, 20 minutes, 50 minutes, etc.; the cooking temperature corresponding to each cooking cavity may be set independently by the user, or obtained through third-party experimental data, such as 120 °C, 180 °C, 200 °C, etc., which is not limited here.

[0076] Exemplarily, the cooking appliance is an air fryer, including functions such as a cooking function and a heat preservation function. The user can press the button corresponding to the air fryer cooking function, and can also set the cooking duration and cooking temperature corresponding to each cooking cavity, and can press the button corresponding to the cooking function again to start the cooking appliance to enter the cooking mode. Among them, the cooking appliance can also enter the cooking mode after timing a preset start duration after receiving the cooking duration and cooking temperature set by the user, and control the heating parameters of the heating device corresponding to the cooking cavity based on the cooking duration and cooking temperature corresponding to the cooking cavity, so as to cook the food placed in the cooking cavity.

[0077] Step S120: Control the working parameters of the at least two heating devices according to the cooking duration and the cooking temperature corresponding to each of the cooking cavities.

[0078] In some embodiments, after the cooking appliance obtains the cooking time and cooking temperature corresponding to each cooking cavity, the working parameters of at least two heating devices included in the cooking appliance can be controlled according to the cooking time and cooking temperature corresponding to each cooking cavity.

[0079] In some embodiments, the cooking appliance can obtain the temperature of the cooking cavity corresponding to each frying bucket collected by the temperature sensing circuit corresponding to each cooking cavity within the cooking time corresponding to each cooking cavity, compare the temperature of each cooking cavity with the first preset temperature corresponding to each cooking cavity, and determine the heating parameter of the heating device corresponding to each cooking cavity according to the comparison result. The cooking appliance can also control the hot air blower corresponding to each cooking cavity to rotate within the cooking time corresponding to each cooking cavity, thereby promoting the flow of high-temperature air in each cooking cavity, improving the uniformity of the temperature of each cooking cavity, and improving the cooking performance and practicality of the cooking appliance.

[0080] As an implementable manner, if the cooking appliance detects that the temperature of each cooking cavity is lower than the first preset temperature corresponding to each cooking cavity, the heating device corresponding to each cooking cavity may be controlled to generate heat in turn until the temperature of each cooking cavity is greater than or equal to the first preset temperature corresponding to each cooking cavity. If the cooking appliance determines that there is a cooking cavity with a temperature lower than the first preset temperature corresponding to the cooking cavity, the heating device corresponding to the cooking cavity with a temperature lower than the first preset temperature of the cooking cavity may be controlled to generate heat in turn.

[0081] The first preset temperature corresponding to each cooking cavity can be the same or different, can be set by the user, or can be obtained through third-party experimental data, which is not limited here. Exemplarily, the first preset temperature corresponding to each cooking cavity is three quarters of the cooking temperature corresponding to each cooking cavity.

[0082] Among them, the cooking appliance controls the heating devices corresponding to each cooking cavity to heat in turn by determining the heating time of the heating device corresponding to any one cooking cavity from each cooking cavity based on the maximum power heating target, and stopping the heating time for the target interval after the heating target time, and then determining the heating time of the heating device corresponding to any one cooking cavity except the cooking cavity from each cooking cavity based on the maximum power heating target, and stopping the heating time for the target interval after the heating target time, and then controlling the heating devices corresponding to each cooking cavity to heat in turn until the temperature of each cooking cavity is greater than or equal to the first preset temperature corresponding to each cooking cavity.

[0083] The target heating time and the target interval time can be preset in the cooking appliance, or the cooking appliance can obtain them from an associated cloud or electronic device through wireless communication technology, or the cooking appliance can obtain them from an associated electronic device through a serial communication interface, which is not limited here. For example, the target heating time is 15 seconds and the target interval time is 2 seconds, which are preset in the cooking appliance.

[0084] As another feasible method, if the cooking appliance detects that the temperature of each cooking cavity is greater than or equal to the first preset temperature corresponding to each cooking cavity, the heating devices corresponding to each cooking cavity can be controlled to generate heat in turn until the deviation between the temperature of each cooking cavity and the cooking temperature corresponding to each cooking cavity is less than the target deviation.

[0085] The target deviation may be pre-set in the cooking appliance, or obtained by the cooking appliance from an associated cloud or electronic device through wireless communication technology, or obtained by the cooking appliance from an associated electronic device through a serial communication interface; the target deviation corresponding to each cooking cavity may be the same or different, which is not limited here.

[0086] Among them, the cooking appliance controls the heating devices corresponding to each cooking cavity to heat in turn in a manner that: from each cooking cavity whose temperature is greater than or equal to the first preset temperature corresponding to the cooking cavity, determine the heating device corresponding to any one cooking cavity to heat based on maximum power until the deviation between the temperature of the cooking cavity and the cooking temperature corresponding to the cooking cavity is less than the target deviation, control the heating element to stop heating; and from each cooking cavity whose temperature is greater than or equal to the first preset temperature corresponding to the cooking cavity, determine the heating device corresponding to any one cooking cavity except the cooking cavity to heat based on maximum power until the deviation between the temperature of the cooking cavity and the cooking temperature corresponding to the cooking cavity is less than the target deviation, control the heating element to stop heating, and then control the heating devices corresponding to each cooking cavity to heat in turn until the deviation between the temperature of each cooking cavity and the cooking temperature corresponding to the cooking cavity is less than the target deviation.

[0087] It can be understood that, based on the cooking function of the cooking device, this embodiment designs at least two cooking cavities, and controls at least two heating systems to heat the load heating tubes corresponding to the at least two cooking cavities, and then controls the fan to blow high-temperature air into the at least two cooking cavities to heat the food. Among them, the heating system control circuit of the cooking device is composed of heating subsystems corresponding to at least two cooking cavities, and each heating subsystem controls the heating heat source in a single cooking cavity to ensure that the food in the cavity can be baked to be crispy on the outside and tender on the inside to meet the user's taste requirements, thereby improving the user's experience.

[0088] The heating method provided by an embodiment of the present application obtains the cooking duration and cooking temperature corresponding to each cooking cavity; controls the operating parameters of at least two heating devices according to the cooking duration and cooking temperature corresponding to each cooking cavity, and then cooks the food in at least two cooking cavities by simultaneously controlling the operating parameters of at least two heating devices, improving the practicability and cooking performance of the cooking appliance.

[0089] Please refer to Figure 8 , Figure 8 which shows a schematic flow chart of the heating method provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance. The following will elaborate in detail on Figure 8 the process shown. The heating method may specifically include the following steps:

[0090] Step S210: Obtain the cooking duration and cooking temperature corresponding to each cooking cavity.

[0091] For the specific description of step S210, please refer to the specific description of step S110 above and will not be elaborated in detail here.

[0092] Step S220: During the process of controlling the cooking appliance to work according to the cooking duration corresponding to each cooking cavity, obtain the temperature of the cooking cavity corresponding to each heating device as the first temperature.

[0093] In some embodiments, the cooking appliance may obtain the temperature of the cooking cavity corresponding to each heating device as the first temperature during the process of controlling the cooking appliance to work according to the cooking duration corresponding to each cooking cavity. Among them, the cooking appliance may obtain the temperature collected by the temperature sensing circuit corresponding to each cooking cavity in real time as the first temperature corresponding to each cooking cavity during the process of controlling the heating device corresponding to each cooking cavity to work according to the cooking duration corresponding to each cooking cavity.

[0094] Step S230: If each of the first temperatures is less than the first temperature threshold, control the at least two heating devices to alternately heat for a first preset duration at a preset time interval until each of the first temperatures is greater than or equal to the first temperature threshold, where the first temperature threshold is less than the cooking temperature.

[0095] In some embodiments, after the cooking appliance obtains the first temperature corresponding to each cooking cavity, it may compare each first temperature with the first temperature threshold, and may determine whether to control the heating device corresponding to each cooking cavity to alternately heat for a first preset duration at a preset time interval until each first temperature is greater than or equal to the first temperature threshold according to the comparison result. Exemplarily, if the cooking appliance determines that each first temperature is less than the first temperature threshold, it may control the heating device corresponding to each cooking cavity to alternately heat for a first preset duration at a preset time interval until each first temperature is greater than or equal to the first temperature threshold.

[0096] Among them, the first temperature threshold is less than the cooking temperature corresponding to each cooking cavity. The first temperature threshold can be preset in the cooking appliance in advance, or can be obtained by the cooking appliance from an associated cloud or electronic device through wireless communication technology, or can also be obtained by the cooking appliance from an electronic device associated through a serial communication interface; among them, the first temperature thresholds corresponding to each cooking cavity can be the same or different, which is not limited here. Exemplarily, the first temperature thresholds corresponding to each cooking cavity can be different and be one-half of the cooking temperature corresponding to each cooking cavity, or the first temperature thresholds corresponding to each cooking cavity can be the same and all be 100 °C.

[0097] Step S240: If each of the first temperatures is greater than or equal to the first temperature threshold, obtain a first deviation between the first temperature corresponding to the first target heating device and the cooking temperature corresponding to the first target heating device, where the first target heating device is any one of the at least two heating devices.

[0098] In some embodiments, after the cooking appliance obtains the first temperature of each cooking cavity, it can compare the first temperature of each cooking cavity with the first temperature threshold corresponding to each cooking cavity, and determine whether to obtain a first deviation between the first temperature corresponding to the first target heating device and the cooking temperature corresponding to the first target heating device according to the comparison result. Exemplarily, if the cooking appliance determines that each first temperature is greater than or equal to the first temperature threshold, it can obtain a first deviation between the first temperature corresponding to the first target heating device and the cooking temperature corresponding to the first target heating device.

[0099] Among them, the first target heating device is any one of the at least two heating devices included in the cooking appliance.

[0100] Step S250: If the first deviation is greater than the first offset, control the first target heating device to continue heating until the first deviation is less than or equal to the first offset, then control the first target heating device to stop heating, and control the operating parameters of the at least two heating devices other than the first target heating device according to the cooking temperature corresponding to each cooking cavity.

[0101] In some embodiments, after the cooking appliance obtains the first deviation between the first temperature corresponding to the first target heating device and the cooking temperature corresponding to the first target heating device, if it is determined that the first deviation is greater than the first offset, it can control the first target heating device to continue heating until the first deviation is less than or equal to the first offset, then control the first target heating device to stop heating, and control the operating parameters of the at least two heating devices other than the first target heating device according to the cooking temperature corresponding to each cooking cavity.

[0102] Among them, a first offset can be preset in the cooking appliance. The first offset can be set by the user independently or obtained from third-party experimental data, which is not limited herein. Exemplarily, the first offset is 0.

[0103] In some embodiments, the process of the cooking appliance controlling the operating parameters of at least two heating devices other than the first target heating device according to the cooking temperature corresponding to each cooking cavity may include determining a second target heating device from at least two heating devices other than the first target heating device, and obtaining a second deviation between the first temperature corresponding to the second target heating device and the cooking temperature corresponding to the second target heating device. Among them, if the cooking appliance determines that the second deviation is greater than the second offset, it may control the second target heating device to continuously heat until the second deviation is less than or equal to the second offset, then control the second target heating device to stop heating, and control the operating parameters of at least two heating devices other than the second target heating device according to the cooking temperature corresponding to each cooking cavity.

[0104] Among them, a second offset can be preset in the cooking appliance. The second offset can be set by the user independently or obtained from third-party experimental data; the second offset can be the same as or different from the first offset, which is not limited herein. Exemplarily, the second offset is 0.

[0105] Exemplarily, please refer to Figure 9 , which shows a schematic flow chart of the heating method provided by an embodiment of the present application. Among them, the cooking appliance can be a double-chamber air fryer; the cooking appliance can obtain a target cooking instruction input by the user, and determine that it is necessary to control the cooking appliance to enter a cooking mode according to the target cooking instruction, and obtain the cooking duration and cooking temperature corresponding to each cooking cavity. Correspondingly, in the process of the cooking appliance controlling the operation of the cooking appliance according to the cooking duration corresponding to each cooking cavity, the temperature of the cooking cavity corresponding to each heating device is obtained as the first temperature. For example, the temperature of the left cavity is obtained as the first temperature, and the temperature of the right cavity is obtained as the first temperature.

[0106] Among them, after the cooking appliance obtains the first temperature of each cooking cavity, it can compare each first temperature with the first temperature threshold. If it is determined that each first temperature is less than the first temperature threshold, it can control the heating device corresponding to the left cavity and the heating device corresponding to the right cavity to alternately heat for the first preset duration based on a preset time interval until each first temperature is greater than or equal to the first temperature threshold. Exemplarily, it is determined whether the temperature of the left cavity reaches T1 (the first temperature threshold), and whether the temperature of the right cavity reaches T1; if it is determined that both the temperature of the left cavity and the temperature of the right cavity are less than T1, the heating device corresponding to the left cavity can be controlled to heat for 15 s (the first preset duration), the heating device corresponding to the right cavity stops heating, and after controlling the heating device corresponding to the left cavity to heat for 15 s, the heating device corresponding to the left cavity and the heating device corresponding to the right cavity are controlled to stop heating for 2 s (the preset time interval). Among them, after the cooking appliance controls the heating device corresponding to the left cavity to alternately heat for the first preset duration based on a preset time interval, it can alternately control the heating device corresponding to the right cavity to alternately heat for the first preset duration based on a preset time interval.

[0107] Among them, during the process that the cooking appliance controls the heating device corresponding to the left cavity and the heating device corresponding to the right cavity to alternately heat for the first preset duration based on a preset time interval, it can obtain the temperature of the left cavity in real time and obtain the temperature of the right cavity, and when it is determined that the temperature of the left cavity and the temperature of the right cavity are greater than or equal to T1, it is determined whether the temperature of the left cavity reaches T2 (the cooking temperature corresponding to the left cavity, where the first offset is 0). If it is less than T2, the heating device corresponding to the left cavity can be controlled to continuously heat, and the heating device corresponding to the right cavity stops heating until the temperature of the left cavity is greater than or equal to T2, and then the heating device corresponding to the left cavity is controlled to stop heating. Correspondingly, the cooking appliance can determine whether the temperature of the right cavity reaches T3 (the cooking temperature corresponding to the right cavity, where the second offset is 0). If it is less than T23, the heating device corresponding to the right cavity can be controlled to continuously heat, and the heating device corresponding to the left cavity stops heating until the temperature of the right cavity is greater than or equal to T3, and then the heating device corresponding to the right cavity is controlled to stop heating.

[0108] Among them, within the cooking duration corresponding to the left cavity and within the cooking duration corresponding to the right cavity, when it is determined that the temperature of the left cavity and the temperature of the right cavity are greater than or equal to T1, the heating device corresponding to the left cavity and the heating device corresponding to the right cavity can be alternately controlled to heat until the temperature of the left cavity reaches T2 and the temperature of the right cavity reaches T3, that is, the left and right cavity heating subsystems are controlled to perform a cyclic heating working procedure in the temperature control program until the cooking duration of each cooking cavity is reached, and then the cooking work of the left and right cavities is ended.

[0109] The heating method provided by an embodiment of the present application, compared with Figure 7For the heating method shown, in this embodiment, during the process of controlling the cooking appliance to work according to the cooking duration corresponding to each cooking cavity, the temperature of the cooking cavity corresponding to each heating device is obtained as the first temperature. If each first temperature is less than the first temperature threshold, at least two heating devices are controlled to heat alternately for a first preset duration based on a preset time interval until each first temperature is greater than or equal to the first temperature threshold, where the first temperature threshold is less than the cooking temperature. If each first temperature is greater than or equal to the first temperature threshold, the first deviation between the first temperature corresponding to the first target heating device and the cooking temperature corresponding to the first target heating device is obtained, where the first target heating device is any one of at least two heating devices. If the first deviation is greater than the first offset amount, the first target heating device is controlled to continuously heat until the first deviation is less than or equal to the first offset amount, and then the first target heating device is controlled to stop heating, and the working parameters of at least two heating devices except the first target heating device are controlled according to the cooking temperature corresponding to each cooking cavity. Thus, by controlling the heating devices corresponding to each cooking cavity to heat alternately, the reliability of food cooking is ensured, and the practicability and cooking performance of the cooking appliance are improved.
