Optionally, the heating element 122 can include a heating tube, a heating plate, etc., which are not limited herein. Exemplarily, the heating element 122 can include a heating tube with parameters of DC voltage 220V, 50Hz, and 1000W.

The heating element 122 is used for heating to raise the temperature of the gas in the cooking cavity, and can also be used for heating during the process of cleaning the heating element 122 to soften the oil stains on the surface of the heating element 122.

[0033] Among them, the spraying device 13 included in the air fryer 100 is arranged in the housing assembly 11, and may include a water storage device 131 and a water outlet device 132. Among them, the water storage device 131 is connected to the water outlet device 132, and the water storage device 131 and the water outlet device 132 are arranged in the housing assembly 11. The water outlet device 132 can be used to spray the water in the water storage device 131 into the cooking cavity. Among them, the spraying device 13 can be fixedly arranged in the housing assembly 11 through a fixing structure. It should be noted that the fixing structure for fixing the heating element 122 and the fixing structure for fixing the spraying device 13 can be the same or different.

[0034] Among them, the detection device 14 included in the air fryer 100 can be arranged on the water storage device 131, and can be used to detect the water storage volume of the water storage device 131 within a preset time period during the operation of the heating device 12.

[0035] In some embodiments, the detection device 14 can include a liquid level sensor. Among them, the liquid level sensor can be arranged at a preset water level line set by the water storage device 131 and connected to the control module 15.

[0036] Among them, the water storage device 131 can include a stepped water tank, and the liquid level sensor can be arranged at the step of the stepped water tank and flush with the preset water level line. Exemplarily, please refer back to Figure 2 Among them, the water storage device 131 can include a stepped water tank, and the liquid level sensor can be arranged at the step of the stepped water tank and flush with the preset water level line X set by the water storage device 131.

[0037] Among them, the liquid level sensor can include a capacitance liquid level sensor, and can include a static pressure type liquid level sensor, which is not limited herein. Among them, the water storage device 131 can include a stepped water tank or an irregularly shaped water tank. Among them, the water tank included in the water storage device 131 is provided with a corresponding preset water level line; among them, the shape of the corresponding water tank can ensure that the liquid level sensor can be arranged in the water tank, and the position of the liquid level sensor is flush with the preset water level line.

[0038] Exemplarily, as Figure 2 shown, the bottom of the water tank included in the water storage device 131 is made into a stepped shape. The liquid level sensor included in the detection device 14 can be a capacitance sensor, closely contact the bottom of the step of the stepped water tank, and be flush with the preset water level line X set by the water tank, and can be installed based on a plastic part, and can also be connected to the electronic control board included in the control module 15.

[0039] Exemplarily, please refer to Figure 3, which shows a schematic diagram of the liquid level sensor detection circuit provided by an embodiment of the present application. Among them, the liquid level sensor detection circuit can be composed of a capacitive liquid level sensor, a resistor R1, a capacitor C1, and a capacitor C2 connected in the manner as Figure 3 shown. Among them, the liquid level sensor detection circuit can convert the detected analog signal of the water level of the water storage device 131 into a digital signal AD and send it to the control module 15, that is, the main control chip as Figure 3 shown. Among them, the capacitive liquid level sensor can include a capacitive liquid level sensor of the XHD-B2P3-WSnT model, R1 can include a resistor of the 0603-1001-F-1 / 10W-T model, C1 can include a capacitor of the C-0603-104K50-X7R model, and C2 can include a capacitor of the -0603-104K50-X7R model, which is not limited here.

[0040] Among them, if the capacitive liquid level sensor is not in contact with water, the signal detected by the AD port of the electronic control board through the capacitive liquid level sensor can be a high level. Correspondingly, the main control chip, that is, the electronic control board, can determine that there is no water in the water storage device 131. Correspondingly, the main control chip can control the buzzer to alarm and remind the user to add water to the water storage device 131, and can also control the heating device 12 and the spraying device 13 to stop working. Correspondingly, the capacitive liquid level sensor can detect the water storage volume of the water storage device 131 in real time. When the amount of water added by the user to the water storage device 131 makes the water level line of the water storage volume in the water storage device 131 reach the preset water level line, that is, the water surface of the water storage device 131 completely covers the capacitive liquid level sensor. Correspondingly, the electronic control board can detect a low level signal through the capacitive liquid level sensor; Correspondingly, the electronic control board can control the heating device 12 and the spraying device 13 to start working normally.

[0041] In some embodiments, please refer to Figure 2 again. The water outlet device 132 can include a water flow passage 321, a water pump 322, and a nozzle 323. Among them, the water pump 322 can be connected to the water storage device 131 through the water flow passage 321 and can be connected to the control module 15. Among them, the control module 15 can be used to control the water pump 322 to transport the water in the water storage device 131 to the nozzle 323 through the water flow passage 321, so that the nozzle 323 sprays water into the cooking cavity. Exemplarily, please refer to Figure 2 again. Among them, the water tank 131 can be installed on the air fryer 10. The water pipe 321 is connected to the bottom of the water tank 131. Among them, the water in the water tank 131 can pass through the water pipe 321 to the water pump 322 and then to the nozzle 323 until it reaches the inside of the frying basket 121.

[0042] Among them, the control module 15 included in the air fryer 100 can be respectively connected to the heating device 12, the spraying device 13, and the detection device 14, and can be used to control the heating device 12 to heat and control the spraying device 13 to spray water into the cooking cavity when it is determined that the water storage amount of the water storage device 131 detected by the detection device 14 is higher than or equal to the preset water level line set by the water storage device 131 within a preset time period.

[0043] In some embodiments, the control module 15 can be connected to the heating element 122 to control the power and duration of the heating element 122 to generate heat; among them, the control module 15 can also be connected to the water pump 322 included in the spraying device 13, and is used to control the moment when the water pump 322 conveys the water in the water storage device 131 to the nozzle 323 through the water flow path 321 during the process of controlling the heating element 122 to work, so that the nozzle 323 sprays water into the cooking cavity.

[0044] In some embodiments, the control module 15 can also be 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 module 15, and the control module 15 can control the air fryer 100 based on this electrical signal. Optionally, the control module 15 is a Micro Controller Unit (MCU). Exemplarily, the control module 15 can include an electronic control board, which can be used for human-computer interaction, data processing, etc.

[0045] Please refer to again Figure 2 In some embodiments, the air fryer 100 can also include a hot air blower 16. Among them, the hot air blower 16 is arranged in the housing assembly 11 and on the side away from the cooking cavity relative to the heating element 122, and is used to blow air to the heating element 122, so that the high-temperature gas generated by the heating of the heating element 122 undergoes a convection cycle in the cooking cavity, thereby cooking the food. Among them, the hot air blower 16 is arranged at an interval from the heating element 122, and the hot air blower 16 is also fixedly arranged in the housing assembly 11 through a fixing structure. It should be noted that the fixing structure for fixing the heating element 122 and the fixing structure for fixing the hot air blower 16 can be the same or different.

[0046] When the air fryer 100 includes the hot air blower 16, the control module 15 can be connected to the hot air blower 16 to control the working parameters of the hot air blower 16, such as the rotation speed and rotation duration of the hot air blower 16. Among them, the hot air blower 16 can include a fan with parameters of DC220V, 50Hz, and 1000W.

[0047] In some embodiments, a temperature detection device may also be provided in the cooking cavity. The temperature detection device may be connected to the control module 15 and is used to obtain the temperature information of the cooking cavity and report it to the control module 15. The control module 15 may adjust the heating power of the heating element 122 based on the obtained temperature information, so as to realize the temperature control of the cooking cavity.

[0048] In some embodiments, the frying bucket 121 may further include a baking tray. The baking tray is detachably disposed in the cooking cavity and is spaced apart from the bottom wall. The baking tray is provided with a food placement portion, and the food placement portion is provided with ventilation grooves. When food is placed on the baking tray, the high-temperature gas generated by the heating of the heating element 122 can contact the bottom surface of the food (the surface where the food contacts the baking tray) through the ventilation grooves, so that the food is heated more evenly.

[0049] In some embodiments, the food placement portion is provided with a weighing device for obtaining the weight of the food placed in the frying bucket 121 and reporting it to the control module 15. The control module 15 may determine the type of food ingredients placed in the frying bucket 121 according to the weight, and may control the heating of the heating element 122 and control the spraying device 13 to spray water into the cooking cavity according to the type of food ingredients, so as to improve the taste of the food after cooking and improve the cooking reliability.

[0050] In some embodiments, the control module 15 may execute this control process after receiving a cooking instruction. This control process includes a water storage amount detection stage and a heating and spraying stage. Among them, in the water storage amount stage, the control module 15 may, during the operation of the heating device 12, obtain the water storage amount of the water storage device 131 detected by the detection device 14 within a preset time period; among them, in the heating and spraying stage, the control module 15 may, when determining that the water storage amount is higher than or equal to the preset water level line set by the water storage device 131, control the heating device 12 to heat and control the spraying device 13 to spray water into the cooking cavity.

[0051] Among them, in the heating and spraying stage, the control module 15 may also, when determining that the water storage amount is lower than the preset water level line set by the water storage device 131, control the heating device 12 and the spraying device 13 to stop working and output a water shortage prompt. Further, if the control module 15 detects that the duration of continuously outputting this water shortage prompt reaches the target duration, it may stop outputting this water shortage prompt and re-detect the water storage amount of the water storage device 131 within a preset time period, so as to identify the water storage situation of the water storage device through the hardware circuit, and when determining that the water storage is normal, control the spraying device 13 to cooperate with the heating device 12 to cook food, effectively improving the taste of the food after cooking and improving the reliability of the air fryer 100.

[0052] Please refer to Figure 4 , Figure 4The flowchart of the control method provided by an embodiment of the present application is shown. The control method identifies the water storage situation of the water storage device through a hardware circuit, and controls the cooperation of the spraying device and the heating device to cook food when it is determined that the water storage is normal, effectively improving the taste of the cooked food and the reliability of the air fryer. In a specific embodiment, the control method can be applied to a control device 200 as shown in Figure 9 and an air fryer 100 configured with the control device 200 ( Figure 10 ). The following will take an electronic device as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the electronic device to which this embodiment is applied can include different types of air fryers. The following will elaborate in detail on the Figure 4 shown process. The control method can specifically include the following steps:

[0053] Step S110: During the operation of the heating device, obtain the water storage volume of the water storage device detected by the detection device within the preset duration.

[0054] In some embodiments, the electronic device can include working modes such as a cleaning mode, a cooking mode, a warming mode, and a standby mode. Among them, in the cleaning mode, the electronic device can clean the heating elements it includes; in the cooking mode, the electronic device can cook the food placed in the frying barrel; in the warming mode, the electronic device can keep the food placed in the frying barrel warm; in the standby mode, each component included in the electronic device is in a standby state. Among them, the electronic device can receive a control instruction input by the user and can switch the working mode of the electronic device based on this control instruction. Exemplarily, the electronic device can receive a first control instruction input by the user in the standby mode and can respond to this first control instruction to switch the working mode of the electronic device to the cooking mode.

[0055] In some embodiments, the electronic device can receive a second control instruction input by the user, and the second control instruction can carry cooking information such as a cooking temperature and a cooking time. Correspondingly, the electronic device can respond to this second control instruction, parse the cooking information such as the cooking temperature and the cooking time carried in the second control instruction, and control the heating device to work based on this cooking information.

[0056] Exemplarily, the electronic device can generate a menu selection interface, obtain cooking information such as a menu selection instruction, a cooking temperature, and a cooking duration input by the user based on this menu selection interface, and enter the cooking mode in response to the user's start instruction.

[0057] In some embodiments, the electronic device may further include an indicator light. Correspondingly, after the electronic device enters the cooking mode, the indicator light corresponding to the cooking mode can indicate by lighting up. Among them, the electronic device may further include a display screen. Correspondingly, after the electronic device enters the cooking mode, the electronic device can generate an interface for cooking countdown and display it on the display screen.

[0058] In some embodiments, during the process of the electronic device entering the cooking mode, the heating device can be controlled to work, and other loads can also be controlled to work. Exemplarily, during the process of the electronic device entering the cooking mode, the heating device can be controlled to perform full-power heating, and the hot air blower can also be controlled to rotate at full speed.

[0059] In some embodiments, a preset duration can be preset in the electronic device; the electronic device can also obtain the preset duration from an associated cloud or electronic device through wireless communication technologies (such as Bluetooth, WiFi, zigbee, etc.); the electronic device can also obtain the preset duration from an associated electronic device through a serial communication interface (such as a serial peripheral interface, etc.). Among them, the preset duration can be set independently by the user or obtained through third-party experimental data, which is not limited here.

[0060] Exemplarily, the preset duration is set independently by the user and pre-stored in the electronic device. For example, the preset duration is 5 minutes from the start of the heating device working.

[0061] In this embodiment, the electronic device can obtain the water storage volume of the water storage device detected by the detection device within the preset duration during the working process of the heating device. Among them, the electronic device can obtain in real time the water storage volume of the water storage device detected by the detection device within the preset duration at the very beginning when the heating device starts to work. Among them, the water storage volume can be understood as the situation of whether the water touches the preset water level line set in the water storage device.

[0062] In some embodiments, the preset water level line set in the water storage device can be preset in the electronic device. The preset water level line can be set independently by the user or obtained through third-party experimental data, which is not limited here. Exemplarily, the preset water level line can be preset in the water storage device and obtained through third-party experimental data. The preset water level line is the water volume required to meet one cooking operation and is set at the 100 ml water volume position of the water storage device.

[0063] Among them, the water storage volume of the water storage device detected by the detection device within the preset duration may include the water level where the water surface completely covers the detection device, or the detection device is not in contact with water.

[0064] Step S120: When it is determined that the water storage amount is higher than or equal to the preset water level line set by the water storage device, control the heating device to heat and control the spraying device to spray water into the cooking cavity.

[0065] In some embodiments, after the electronic device obtains the water storage amount of the water storage device within a preset time period, it can determine the positional relationship between the water storage amount and the preset water level line set by the water storage device, and can determine whether to control the heating device to continue heating based on this positional relationship, and can determine whether to control the spraying device to spray water into the cooking cavity based on this positional relationship. Exemplarily, when it is determined that the water storage amount is higher than or equal to the preset water level line set by the water storage device, the electronic device can control the heating device to heat and can control the spraying device to spray water into the cooking cavity; or when it is determined that the water storage amount is lower than the preset water level line set by the water storage device, it can control the heating device to stop heating and can control the spraying device to stop working.

[0066] Among them, when the electronic device determines that the water storage amount is higher than or equal to the preset water level line set by the water storage device, it can control the heating device to heat at full power.

Furthermore, it identifies the water storage situation of the water storage device through a hardware circuit, and when it is determined that the water storage is normal, controls the spraying device and the heating device to cooperate for food cooking, effectively improving the taste of the cooked food and enhancing the reliability of the air fryer.

[0073] Please refer to Figure 5 , Figure 5 which shows a schematic flowchart of the control method provided by an embodiment of the present application. This method is applied to the above-mentioned electronic device, and the electronic device may include the air fryer provided by an embodiment of the present application. The following will elaborate in detail on Figure 5 the process shown. The control method may specifically include the following steps:

[0074] Step S210: During the operation of the heating device, obtain the water storage amount of the water storage device detected by the detection device within the preset duration.

[0075] For the specific description of step S210, please refer to the specific description of step S110 above and will not be elaborated here in detail.

[0076] Step S220: In the case where it is determined that the water storage amount is lower than the preset water level line set by the water storage device, control the heating device and the spraying device to stop working and output a water shortage prompt.

[0077] In some embodiments, after the electronic device obtains the water storage volume of the water storage device within a preset time period, it may determine the positional relationship between the water storage volume and the preset water level line set for the water storage device, and may determine whether to control the heating device to stop heating and output a water shortage prompt according to this positional relationship. Exemplarily, when it is determined that the water storage volume is lower than the preset water level line set for the water storage device, the electronic device may control the heating device and the spraying device to stop working and output a water shortage prompt.

[0078] Among them, when the electronic device determines that the water storage volume is lower than the preset water level line set for the water storage device, it may determine that the detection device is not in contact with water; correspondingly, the electronic device may turn off the heating device and the water storage device to ensure the taste of the cooked food; among them, the electronic device may also output a water shortage prompt. Among them, the way of outputting the water shortage prompt may include prompt methods such as an indicator light prompt method, a buzzer prompt method, and an interface display prompt method.

[0079] Exemplarily, when the electronic device determines that the water storage volume is lower than the preset water level line set for the water storage device, it may control the buzzer to sound continuously and the water shortage indicator light of the digital tube to flash continuously to prompt the user to add water to the water tank.

[0080] Step S230: If the duration of continuously outputting the water shortage prompt reaches the target duration, stop outputting the water shortage prompt, and re-detect the water storage volume of the water storage device within the preset time period.

[0081] In some embodiments, a target duration may be preset in the electronic device. Among them, the target duration may be set independently by the user or obtained through third-party experimental data, which is not limited herein. Exemplarily, the target duration of 10 s is set independently by the user.

[0082] As an implementable manner, the electronic device may continuously output a water shortage prompt based on the target duration; correspondingly, if the electronic device detects that the duration of continuously outputting the water shortage prompt reaches the target duration, it may stop outputting the water shortage prompt and may re-detect the water storage volume of the water storage device within the preset time period.

[0083] Among them, when the electronic device determines that the water storage volume is lower than the preset water level line set for the water storage device, it may control the heating device and the spraying device to stop working and output a water shortage prompt to remind the user to add water. Further, if the electronic device detects that the duration of continuously outputting the water shortage prompt reaches the target duration, it may stop outputting the water shortage prompt and may restart the heating device and the spraying device to work; correspondingly, the electronic device may control the detection device to re-detect the water storage volume of the water storage device within the preset time period when the heating device is restarted.

[0084] Among them, if the electronic device re-detects the water storage volume of the water storage device and determines that the water storage volume is higher than or equal to the preset water level line set by the water storage device, it can control the heating device to continue heating and control the spraying device to spray water into the cooking cavity.

[0085] As another implementable manner, the electronic device can continuously output a water shortage prompt based on the target duration; correspondingly, the electronic device can detect the water storage volume of the water storage device in real time while outputting the water shortage prompt. If it is detected that the water storage volume is higher than or equal to the preset water level line set by the water storage device, it can stop outputting the water shortage prompt and can restart the heating device and the spraying device to work; correspondingly, the electronic device can control the detection device to re-detect the water storage volume of the water storage device within the preset duration when the heating device restarts to work, and execute the subsequent steps of controlling the heating device to continue heating and controlling the spraying device to spray water into the cooking cavity when the detected water storage volume is higher than or equal to the preset water level line set by the water storage device.

[0086] It can be understood that in this embodiment, the electronic device can identify the water storage volume while controlling the heating device to generate heat, and can spray the water in the water storage device onto the food in the cooking cavity through the water outlet device, and then cooperate heating and spraying to cook the food, effectively locking the moisture of the food itself, effectively improving the taste of the food, improving the menu performance of the electronic device for cooking, and improving the user experience.

[0087] The control method provided by an embodiment of the present application, compared with Figure 3 the shown control method, in this embodiment, when it is determined that the water storage volume is lower than the preset water level line set by the water storage device, it can also control the heating device and the spraying device to stop working, output a water shortage prompt, and if the duration of continuously outputting the water shortage prompt reaches the target duration, stop outputting the water shortage prompt, re-detect the water storage volume of the water storage device within the preset duration, detect whether the water storage volume in the water storage device is abnormal through the hardware circuit, and perform software alarm in the case of determining abnormality to remind the user to add water, thereby effectively improving the taste of the food, improving the menu performance of the electronic device for cooking, improving the reliability of the air fryer, and improving the user experience.

[0088] Please refer to Figure 6 , Figure 6 shows a schematic flow chart of the control method provided by an embodiment of the present application. This method is applied to the above-mentioned electronic device, and the electronic device can include the air fryer provided by an embodiment of the present application. The following will elaborate in detail on Figure 6 the shown process. The control method can specifically include the following steps:

[0089] Step S310: Obtain a cooking instruction, where the cooking instruction includes a target cooking duration, and the target cooking duration is greater than the preset duration.

[0090] In some embodiments, the electronic device may receive a cooking instruction input by a user, where the cooking instruction may include a target cooking duration. The electronic device may obtain the cooking instruction from an associated cloud or the electronic device.

[0091] Exemplarily, the electronic device may display a function selection interface. Correspondingly, the electronic device may detect the pressing state of the screen to obtain the cooking instruction input by the user; the electronic device may also collect audio data through a sound pickup device and obtain the cooking instruction input by the user by parsing the audio data. The electronic device may perform keyword detection on the audio data through a preset keyword detection model (such as a convolutional neural network CNN, a recurrent neural network RNN, etc.) to obtain the cooking instruction input by the user.

[0092] The cooking instruction may include cooking information such as a target cooking duration, a preset duration, a cooking temperature, a preset spraying time, and a preset spraying duration. Exemplarily, the target cooking duration may be a duration greater than the preset duration and above 1 min.

[0093] Step S320: In response to the cooking instruction, control the heating device to work based on the target cooking duration.

[0094] In this embodiment, after the electronic device obtains the cooking instruction, it may, in response to the cooking instruction, control the heating device to work based on the target cooking duration. The electronic device may detect the temperature of the cooking cavity in real time through a temperature sensor and may control the heating power of the heating device according to the temperature.

[0095] Step S330: During the operation of the heating device, obtain the water storage amount of the water storage device detected by the detection device within the preset duration.

[0096] Step S340: In the case where it is determined that the water storage amount is higher than or equal to the preset water level line set by the water storage device, control the heating device to heat.

[0097] For the specific descriptions of steps S330 - S340, please refer to the specific descriptions of steps S110 - S120 above, and details will not be repeated here.

[0098] Step S350: Time the operation time of the heating device to obtain a target timing.

[0099] In some embodiments, during the process that the electronic device controls the heating device to work based on the target cooking duration, the water storage amount detected by the detection device can be obtained within a preset duration after starting the heating of the heating device, and the positional relationship between the water storage amount and the preset water level line set for the water storage device can be determined; wherein, in the case that it is determined that the water storage amount is higher than or equal to the preset water level line set for the water storage device, the heating device can be controlled to continue heating, and the working time of the heating device can be timed to obtain the target timing.

[0100] Wherein, the target timing can include the timing of the electronic device controlling the heating device to work based on the target cooking duration.

[0101] Step S360: If the target timing meets the preset water spraying moment, control the spraying device to spray water into the cooking cavity for a preset spraying duration.

[0102] In some embodiments, during the process that the electronic device obtains the target timing in real time, the target timing can be matched with the preset water spraying moment. If the target timing meets the preset water spraying moment, the spraying device can be controlled to spray water into the cooking cavity for a preset spraying duration.

[0103] Wherein, the preset water spraying moment can include one or more; wherein, the matching of the target timing and the preset water spraying moment can indicate that there is a preset water spraying moment that is the same as the target timing.

[0104] Optionally, the preset spraying durations corresponding to different preset water spraying moments can be the same or different. Wherein, the process of controlling the spraying device to spray water into the cooking cavity for a preset spraying duration if the target timing meets the preset water spraying moment can include, if there is a preset water spraying moment that is the same as the target timing, it is determined that the target timing meets the preset water spraying moment, the preset spraying duration corresponding to the preset water spraying moment can be obtained, and the spraying device can be controlled to spray water into the cooking cavity for the preset spraying duration.

[0105] In some embodiments, before the electronic device controls the spraying device to spray water into the cooking cavity, the type of the food ingredients included in the cooking cavity can also be obtained, and the preset water spraying moment and the preset spraying duration can be determined according to the type of the food ingredients.

[0106] Optionally, a corresponding relationship between the type of food ingredients and the preset water spraying moment and the preset spraying duration can be preset in the electronic device, and the electronic device can also obtain the corresponding relationship from an associated cloud or the electronic device, which is not limited herein. Exemplarily, the corresponding relationship can include a mapping relationship table between the type of food ingredients and the preset water spraying moment and the preset spraying duration.

[0107] Among them, the ways for the electronic device to obtain the food ingredient type may include obtaining the weight of the food in the frying bucket and determining the food ingredient type according to the weight; among them, the electronic device may also include a camera, and the electronic device may obtain an image including the food in the frying bucket through the camera and determine the food ingredient type according to the image; the electronic device may also obtain the food ingredient type input by the user.

[0108] Correspondingly, after the electronic device obtains the food ingredient type, it may obtain the preset water spraying time and the preset spraying duration corresponding to the food ingredient type based on the corresponding relationship between the food ingredient type and the preset water spraying time and the preset spraying duration, and may control the spraying device to spray water into the cooking cavity for the preset spraying duration when it is determined that the target timing meets the preset water spraying time.

[0109] Exemplarily, please refer to Figure 7 and Figure 8 , where Figure 7 shows a schematic flowchart of the cooking process of the electronic device provided by an embodiment of the present application. Among them, the electronic device may obtain a cooking instruction, and in response to the cooking instruction, control the heating device and the spraying device to work based on the target cooking duration included in the cooking instruction until the countdown of the target cooking duration reaches 0, it may be determined that the electronic device has completed the cooking corresponding to the cooking instruction, and the electronic device may be controlled to enter the standby mode; if the countdown of the target cooking duration has not reached 0, the heating device and the spraying device may continue to be controlled to work.

[0110] Among them, Figure 8 shows a schematic flowchart of the control method provided by an embodiment of the present application. Among them, the electronic device may obtain a cooking instruction, where the cooking instruction may include a function selection instruction (such as a cooking function instruction), a cooking temperature, and a target cooking duration of the electronic device. Correspondingly, the electronic device may enter the cooking mode in response to the cooking instruction, and may control the indicator light corresponding to the cooking function to turn on, and may also display a countdown interface corresponding to the target cooking duration on the screen. Among them, after the electronic device enters the cooking mode, it may detect the temperature of the frying bucket in real time, may also control the heating device to perform full-power heating, and may also control the hot air blower to rotate at full speed. Correspondingly, the electronic device may control the detection device to detect the water storage volume of the water storage device in real time within T1 (preset duration) after starting the heating device to work, and determine whether a high level is detected by the detection device within the T1 duration. If a high level is detected, it may be determined that the water storage volume is lower than the preset water level line set by the water storage device, and the electronic device may control the heating device, the hot air blower, and the spraying device to stop working and output a water shortage prompt to prompt the user to add water to ensure the safety and reliability of cooking.

[0111] Correspondingly, after the duration of continuously outputting the water shortage prompt reaches the target duration, the electronic device can stop outputting the water shortage prompt, and can return to the steps of controlling the heating device to heat at full power and controlling the hot air blower to work at full speed, so as to re-detect the water storage volume of the water storage device within the preset duration of the heating device working.

[0112] Among them, if the electronic device does not detect a high level through the detection device within the T1 duration, it can continue to control the heating device to heat at full power and control the hot air blower to work at full speed, and can time the working time of the heating device to obtain the target timing. Correspondingly, when the target timing meets the preset water spraying moment (S1 moment), the electronic device can control the spraying device to spray water into the cooking cavity for the preset spraying duration (T2 duration); the electronic device can also control the spraying device to spray water into the cooking cavity for the preset spraying duration (T2 duration) when the target timing meets the preset water spraying moment (S2 moment); the electronic device can also control the spraying device to spray water into the cooking cavity for the preset spraying duration (T2 duration) when the target timing meets the preset water spraying moment (S3 moment), until the countdown of the target cooking duration is 0, and the electronic device can be controlled to enter the standby mode.

[0113] It can be understood that in this embodiment, the hardware circuit is used to detect whether the water storage volume in the water storage device is abnormal, and when the water storage volume is normal, the heating device and the spraying device are controlled to cooperate for food cooking, thereby effectively locking the moisture in the food itself, effectively improving the food taste, and improving the reliability of the electronic device for cooking. In addition, in the case of abnormal water storage volume, software alarm is carried out to remind the user to add water, so as to ensure the safety and reliability of cooking, and also improve the user experience.

[0114] The control method provided by an embodiment of the present application, compared with Figure 3 the shown control method, before obtaining the water storage volume of the water storage device detected by the detection device within the preset duration, this embodiment can also obtain a cooking instruction, the cooking instruction includes a target cooking duration, the target cooking duration is greater than the preset duration, and in response to the cooking instruction, control the heating device to work based on the target cooking duration, and time the working time of the heating device to obtain the target timing. If the target timing meets the preset water spraying moment, control the spraying device to spray water into the cooking cavity for the preset spraying duration, thereby when the water storage volume is normal, control the heating device and the spraying device to cooperate for food cooking, effectively locking the moisture in the food itself, effectively improving the food taste, improving the reliability of the electronic device for cooking, and in the case of abnormal water storage volume, carrying out software alarm to remind the user to add water, so as to ensure the safety and reliability of cooking, and improve the user experience.
