Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to an air fryer and its control method, apparatus, and readable storage medium. Background Technology

[0002] Currently, air fryers using electromagnetic heating technology are characterized by self-heating fan blades. The surface temperature of these blades is extremely high, and their thickness is relatively large, resulting in significant heat storage. Even after the air fryer stops operating, the fan blade temperature remains high, which can easily cause excessive temperature rise and damage to components such as the coil, motor, and power board inside the top cover cavity, thus reducing the air fryer's lifespan. Summary of the Invention

[0003] The embodiments of the present invention are intended to at least solve one of the technical problems existing in the prior art.

[0004] Therefore, a first aspect of the present invention provides a method for controlling an air fryer.

[0005] A second aspect of the present invention provides a control device for an air fryer.

[0006] A third aspect of the present invention provides a control device for an air fryer.

[0007] A fourth aspect of the present invention provides a readable storage medium.

[0008] A fifth aspect of the present invention provides an air fryer.

[0009] In view of the above, according to a first aspect of the present invention, a control method for an air fryer is provided. The air fryer includes a fan blade and a coil, the coil being opposite to the fan blade. The control method includes: controlling the coil to be energized so that at least a portion of the fan blade heats up; and, when the cooking time reaches a first duration, controlling the coil to be de-energized so that the fan blade stops heating up, and controlling the fan blade to rotate for a second duration.

[0010] The air fryer provided in this embodiment of the invention includes a fan blade and a coil. The coil is opposite to the fan blade. Specifically, the coil can generate an alternating magnetic field when energized. The magnetically conductive fan blade heats up under the action of the alternating magnetic field, causing the temperature of the cooking cavity of the air fryer to rise rapidly. At the same time, the fan blade can also rotate inside the cooking cavity, quickly dissipating the heat generated by the fan blade, forming a hot airflow circulating inside the cooking cavity, thereby achieving the heating and cooking of the food inside the cooking cavity.

[0011] Understandably, the fan blades themselves generate heat and have a certain thickness. Furthermore, to ensure the heating power of the air fryer, the fan blades are generally quite thick, thus possessing a certain heat retention capacity. When cooking is complete and the air fryer stops working, the fan blades still maintain a high temperature. This high temperature can easily radiate to the air fryer's electronic control components, causing them to overheat and become damaged.

[0012] Once the first cooking time is reached, the control coil is de-energized to stop the fan from heating, but the fan continues to rotate for a second time. Specifically, the fan can be stopped heating and allowed to continue rotating during air fryer cooking, or it can be stopped heating and allowed to continue rotating after air fryer cooking is finished. The specific settings can be adjusted according to actual needs.

[0013] In other words, after the fan blades stop heating, they will continue to rotate for a second period of time. The fan blades stop heating and stop rotating at different times, which allows the heat stored in the fan blades to be fully dissipated. This effectively prevents the high-temperature fan blades from transferring heat to other electronic components after the air fryer stops working, thus preventing the electronic components from overheating and extending the service life of the entire machine.

[0014] Optionally, the first duration is equal to the cooking time. That is, when the machine finishes cooking and stops working, the fan blades continue to rotate for a second duration to dissipate its own heat.

[0015] Optionally, the first duration is shorter than the cooking time. That is, before the cooking is finished, the fan stops heating and continues to rotate for a second duration to dissipate its own heat.

[0016] Specifically, the first duration plus the second duration can equal the cooking time, meaning cooking ends immediately after the fan continues rotating for the second duration. Alternatively, the first duration plus the second duration can be greater than the cooking time, meaning cooking ends before the fan continues rotating for the second duration. Or, the first duration plus the second duration can be less than the cooking time, meaning cooking is not finished after the fan continues rotating for the second duration, and the coil is energized to reheat the fan. The specific settings can be configured according to actual needs.

[0017] In addition, the air fryer control method provided by the above-described technical solution of the present invention also has the following additional technical features:

[0018] In some technical solutions, the air fryer may optionally include a motor connected to a fan blade, which controls the fan blade to rotate for a second duration, specifically including controlling the motor to run for a second duration.

[0019] In this technical solution, the air fryer is also included as a motor. Specifically, the motor is connected to the fan blades, meaning that the fan blades can rotate under the drive of the motor.

[0020] When the cooking time reaches the first set time, the control coil is powered off. At the same time, the motor drives the fan blades to continue rotating to fully dissipate the heat stored in the fan blades. This prevents the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components when the machine is finished working, thus preventing them from being damaged due to excessive temperature rise. This extends the service life of the air fryer.

[0021] In some technical solutions, optionally, the first duration is the total cooking time of the air fryer.

[0022] In this technical solution, the first time is defined as the total cooking time of the air fryer. That is to say, when the cooking time of the air fryer reaches the first time, the air fryer finishes working, that is, the food has been cooked and the whole machine stops working. At this time, the fan blades are controlled to continue rotating for a second time to fully dissipate their stored heat and prevent the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components.

[0023] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting airflow allows the cooked food inside the cooking cavity to cool down evenly, resulting in a better overall appearance and ensuring the taste of the food.

[0024] In some technical solutions, optionally, the first duration is less than the total cooking time of the air fryer.

[0025] In this technical solution, the first cooking time is limited to less than the total cooking time of the air fryer. In other words, before the machine finishes working, the fan blades stop heating and continue to rotate for a second time to dissipate their own heat, thereby preventing the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components.

[0026] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting hot airflow can heat or assist in heating the food inside the cooking cavity, thereby shortening the heating time of the air fryer, which in turn shortens the heating time of the fan blades. This extends the lifespan of the air fryer while also saving energy.

[0027] In some technical solutions, optionally, the total cooking time t of the air fryer, the first time t1, and the second time t2 satisfy t = t1 + t2.

[0028] In this technical solution, the total cooking time of the air fryer is defined as the sum of the first and second cooking times. That is, when the cooking time reaches the first cooking time, the food in the cooking chamber has been cooked or is basically cooked. When the fan stops heating and continues to rotate for the second cooking time, the air fryer has finished working. This is indicated on the air fryer's display screen when the user is notified that the work is finished, and the fan has rotated for the second cooking time.

[0029] In some technical solutions, optionally, the second duration t2 satisfies 5s≤t2≤30s.

[0030] In this technical solution, the second duration is limited to between 5 and 30 seconds, which allows the heat from the fan blades to dissipate fully when the fan blades stop heating, while ensuring the taste of the food and thus improving the user experience.

[0031] Understandably, if the second duration is too short, i.e. less than 5 seconds, meaning that the fan blades continue to rotate for less than 5 seconds after they stop heating up, the heat stored in the fan blades cannot be completely dissipated, which can easily lead to a temperature rise in the electronic control components and affect the reliability of the air fryer.

[0032] If the second duration is too long, i.e. more than 30 seconds, meaning that the fan blades continue to rotate for more than 30 seconds after they stop heating up, although this ensures that the heat stored in the fan blades is completely dissipated, the food temperature will be lower due to the prolonged rotation of the fan blades, affecting the taste of the food and increasing the user's waiting time, thus impacting the user experience.

[0033] According to a second aspect of the present invention, a control device for an air fryer is provided. The air fryer includes a fan blade and a coil, the coil being opposite to the fan blade. The control device includes a processing unit, which controls the coil to be energized so that at least a portion of the fan blade heats up. The processing unit is also configured to de-energize the coil when the cooking time reaches a first duration, so that the fan blade stops heating up, and to control the fan blade to rotate for a second duration.

[0034] The air fryer provided in this embodiment of the invention includes a fan blade and a coil. The coil is opposite to the fan blade. Specifically, the coil can generate an alternating magnetic field when energized. The magnetically conductive fan blade heats up under the action of the alternating magnetic field, causing the temperature of the cooking cavity of the air fryer to rise rapidly. At the same time, the fan blade can also rotate inside the cooking cavity, quickly dissipating the heat generated by the fan blade, forming a hot airflow circulating inside the cooking cavity, thereby achieving the heating and cooking of the food inside the cooking cavity.

[0035] Understandably, the fan blades themselves generate heat and have a certain thickness. Furthermore, to ensure the heating power of the air fryer, the fan blades are generally quite thick, thus possessing a certain heat retention capacity. When cooking is complete and the air fryer stops working, the fan blades still maintain a high temperature. This high temperature can easily radiate to the air fryer's electronic control components, causing them to overheat and become damaged.

[0036] Once the first cooking time is reached, the control coil is de-energized to stop the fan from heating, but the fan continues to rotate for a second time. Specifically, the fan can be stopped heating and allowed to continue rotating during air fryer cooking, or it can be stopped heating and allowed to continue rotating after air fryer cooking is finished. The specific settings can be adjusted according to actual needs.

[0037] In other words, after the fan blades stop heating, they will continue to rotate for a second period of time. The fan blades stop heating and stop rotating at different times, which allows the heat stored in the fan blades to be fully dissipated. This effectively prevents the high-temperature fan blades from transferring heat to other electronic components after the air fryer stops working, thus preventing the electronic components from overheating and extending the service life of the entire machine.

[0038] Optionally, the first duration is equal to the cooking time. That is, when the machine finishes cooking and stops working, the fan blades continue to rotate for a second duration to dissipate its own heat.

[0039] Optionally, the first duration is shorter than the cooking time. That is, before the cooking is finished, the fan stops heating and continues to rotate for a second duration to dissipate its own heat.

[0040] Specifically, the first duration plus the second duration can equal the cooking time, meaning cooking ends immediately after the fan continues rotating for the second duration. Alternatively, the first duration plus the second duration can be greater than the cooking time, meaning cooking ends before the fan continues rotating for the second duration. Or, the first duration plus the second duration can be less than the cooking time, meaning cooking is not finished after the fan continues rotating for the second duration, and the coil is energized to reheat the fan. The specific settings can be configured according to actual needs.

[0041] In addition, the control device for the air fryer provided by the above-described technical solution of the present invention also has the following additional technical features:

[0042] In some technical solutions, the air fryer may optionally include a motor connected to a fan blade, and the processing unit is specifically used to control the second duration of motor operation.

[0043] In this technical solution, the air fryer is also included as a motor. Specifically, the motor is connected to the fan blades, meaning that the fan blades can rotate under the drive of the motor.

[0044] When the cooking time reaches the first set time, the control coil is powered off. At the same time, the motor drives the fan blades to continue rotating to fully dissipate the heat stored in the fan blades. This prevents the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components when the machine is finished working, thus preventing them from being damaged due to excessive temperature rise. This extends the service life of the air fryer.

[0045] In some technical solutions, optionally, the first duration is the total cooking time of the air fryer.

[0046] In this technical solution, the first time is defined as the total cooking time of the air fryer. That is to say, when the cooking time of the air fryer reaches the first time, the air fryer finishes working, that is, the food has been cooked and the whole machine stops working. At this time, the fan blades are controlled to continue rotating for a second time to fully dissipate their stored heat and prevent the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components.

[0047] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting airflow allows the cooked food inside the cooking cavity to cool down evenly, resulting in a better overall appearance and ensuring the taste of the food.

[0048] In some technical solutions, optionally, the first duration is less than the total cooking time of the air fryer.

[0049] In this technical solution, the first cooking time is limited to less than the total cooking time of the air fryer. In other words, before the machine finishes working, the fan blades stop heating and continue to rotate for a second time to dissipate their own heat, thereby preventing the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components.

[0050] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting hot airflow can heat or assist in heating the food inside the cooking cavity, thereby shortening the heating time of the air fryer, which in turn shortens the heating time of the fan blades. This extends the lifespan of the air fryer while also saving energy.

[0051] In some technical solutions, optionally, the total cooking time t of the air fryer, the first time t1, and the second time t2 satisfy t = t1 + t2.

[0052] In this technical solution, the total cooking time of the air fryer is defined as the sum of the first and second cooking times. That is, when the cooking time reaches the first cooking time, the food in the cooking chamber has been cooked or is basically cooked. When the fan stops heating and continues to rotate for the second cooking time, the air fryer has finished working. This is indicated on the air fryer's display screen when the user is notified that the work is finished, and the fan has rotated for the second cooking time.

[0053] In some technical solutions, optionally, the second duration t2 satisfies 5s≤t2≤30s.

[0054] In this technical solution, the second duration is limited to between 5 and 30 seconds, which allows the heat from the fan blades to dissipate fully when the fan blades stop heating, while ensuring the taste of the food and thus improving the user experience.

[0055] Understandably, if the second duration is too short, i.e. less than 5 seconds, meaning that the fan blades continue to rotate for less than 5 seconds after they stop heating up, the heat stored in the fan blades cannot be completely dissipated, which can easily lead to a temperature rise in the electronic control components and affect the reliability of the air fryer.

[0056] If the second duration is too long, i.e. more than 30 seconds, meaning that the fan blades continue to rotate for more than 30 seconds after they stop heating up, although this ensures that the heat stored in the fan blades is completely dissipated, the food temperature will be lower due to the prolonged rotation of the fan blades, affecting the taste of the food and increasing the user's waiting time, thus impacting the user experience.

[0057] According to a third aspect of the present invention, a control device for an air fryer is provided, comprising a controller and a memory, wherein the memory stores a program or instructions, and the controller implements the air fryer control method as described in any of the above technical solutions when executing the program or instructions in the memory, thus possessing all the beneficial technical effects of the control method, which will not be elaborated further here.

[0058] According to a fourth aspect of the present invention, a readable storage medium is provided, on which a program or instructions are stored. When the program or instructions are executed by a processor, the program or instructions implement the control method of an air fryer as described above, and thus possess all the beneficial technical effects of the control method, which will not be elaborated further here.

[0071] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0072] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0073] The following reference Figures 1 to 7This invention describes a control method for an air fryer, a control device for an air fryer, a readable storage medium, and an air fryer 100 provided according to some embodiments of the invention.

[0074] In one embodiment of the invention, such as Figure 1 As shown, a control method for an air fryer is proposed. The air fryer includes a fan blade and a coil, with the coil opposite to the fan blade. The control method includes:

[0075] Step 102: Control the coil to be energized so that at least a part of the fan blades heats up;

[0076] Step 104: When the cooking time reaches the first duration, de-energize the coil to stop the fan from heating, and control the fan to rotate for the second duration.

[0077] The air fryer provided in this embodiment of the invention includes a fan blade and a coil. The coil is opposite to the fan blade. Specifically, the coil can generate an alternating magnetic field when energized. The magnetically conductive fan blade heats up under the action of the alternating magnetic field, causing the temperature of the cooking cavity of the air fryer to rise rapidly. At the same time, the fan blade can also rotate inside the cooking cavity, quickly dissipating the heat generated by the fan blade, forming a hot airflow circulating inside the cooking cavity, thereby achieving the heating and cooking of the food inside the cooking cavity.

[0078] Understandably, the fan blades themselves generate heat and have a certain thickness. Furthermore, to ensure the heating power of the air fryer, the fan blades are generally quite thick, thus possessing a certain heat retention capacity. When cooking is complete and the air fryer stops working, the fan blades still maintain a high temperature. This high temperature can easily radiate to the air fryer's electronic control components, causing them to overheat and become damaged.

[0079] Once the first cooking time is reached, the control coil is de-energized to stop the fan from heating, but the fan continues to rotate for a second time. Specifically, the fan can be stopped heating and allowed to continue rotating during air fryer cooking, or it can be stopped heating and allowed to continue rotating after air fryer cooking is finished. The specific settings can be adjusted according to actual needs.

[0080] In other words, after the fan blades stop heating, they will continue to rotate for a second period of time. The fan blades stop heating and stop rotating at different times, which allows the heat stored in the fan blades to be fully dissipated. This effectively prevents the high-temperature fan blades from transferring heat to other electronic components after the air fryer stops working, thus preventing the electronic components from overheating and extending the service life of the entire machine.

[0081] Optionally, the first duration is equal to the cooking time. That is, when the machine finishes cooking and stops working, the fan blades continue to rotate for a second duration to dissipate its own heat.

[0082] Optionally, the first duration is shorter than the cooking time. That is, before the cooking is finished, the fan stops heating and continues to rotate for a second duration to dissipate its own heat.

[0083] Specifically, the first duration plus the second duration can equal the cooking time, meaning cooking ends immediately after the fan continues rotating for the second duration. Alternatively, the first duration plus the second duration can be greater than the cooking time, meaning cooking ends before the fan continues rotating for the second duration. Or, the first duration plus the second duration can be less than the cooking time, meaning cooking is not finished after the fan continues rotating for the second duration, and the coil is energized to reheat the fan. The specific settings can be configured according to actual needs.

[0084] In some embodiments, the air fryer may optionally include a motor connected to a fan blade, which controls the fan blade to rotate for a second duration, specifically including controlling the motor to run for a second duration.

[0085] In this embodiment, the air fryer is further defined as including a motor. Specifically, the motor is connected to the fan blades, meaning that the fan blades can rotate under the drive of the motor.

[0086] When the cooking time reaches the first set time, the control coil is powered off. At the same time, the motor drives the fan blades to continue rotating to fully dissipate the heat stored in the fan blades. This prevents the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components when the machine is finished working, thus preventing them from being damaged due to excessive temperature rise. This extends the service life of the air fryer.

[0087] In some embodiments, the first duration may optionally be the total cooking time of the air fryer.

[0088] In this embodiment, the first duration is defined as the total cooking time of the air fryer. That is, when the cooking time of the air fryer reaches the first duration, the air fryer finishes its operation, that is, the food has been cooked and the whole machine stops working. At this time, the fan blades are controlled to continue rotating for a second duration to fully dissipate their stored heat and prevent the high temperature generated by the fan blades themselves from being transferred to the coil, motor, power board and other electronic control devices.

[0089] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting airflow allows the cooked food inside the cooking cavity to cool down evenly, resulting in a better overall appearance and ensuring the taste of the food.

[0090] For example, chicken wings need 15 minutes to bake, that is, the total cooking time is 15 minutes, or the first cooking time is 15 minutes.

[0091] In some embodiments, the first duration may be less than the total cooking time of the air fryer.

[0092] In this embodiment, the first duration is limited to less than the total cooking time of the air fryer. That is, before the entire machine finishes working, the fan blades stop heating and continue to rotate for a second duration to dissipate their own heat, thereby preventing the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control devices.

[0093] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting hot airflow can heat or assist in heating the food inside the cooking cavity, thereby shortening the heating time of the air fryer, which in turn shortens the heating time of the fan blades. This extends the lifespan of the air fryer while also saving energy.

[0094] For example, chicken wings need 15 minutes to bake, meaning the total cooking time is 15 minutes, with the first cooking time being 14 minutes, 13 minutes, or 12 minutes.

[0095] In some embodiments, optionally, the total cooking time t of the air fryer, the first time t1, and the second time t2 satisfy t = t1 + t2.

[0096] In this embodiment, the total cooking time of the air fryer is defined as the sum of the first and second cooking times. That is, when the cooking time reaches the first cooking time, the food in the cooking chamber has been cooked or is basically cooked. When the fan stops heating and continues to rotate for the second cooking time, the air fryer has finished working. This means that the air fryer's display interface will indicate to the user that the work is finished when the fan has rotated for the second cooking time.

[0097] For example, chicken wings need 15 minutes to bake, meaning the total cooking time is 15 minutes, with the first time being 14 minutes and 30 seconds and the second time being 30 seconds.

[0098] In some embodiments, the second duration t2 may optionally satisfy 5s≤t2≤30s.

[0099] In this embodiment, the second duration is limited to between 5 seconds and 30 seconds, so that when the fan blades stop heating, the heat of the fan blades themselves can be fully dissipated while ensuring the taste of the food, thereby improving the user experience.

[0100] Understandably, if the second duration is too short, i.e. less than 5 seconds, meaning that the fan blades continue to rotate for less than 5 seconds after they stop heating up, the heat stored in the fan blades cannot be completely dissipated, which can easily lead to a temperature rise in the electronic control components and affect the reliability of the air fryer.

[0101] If the second duration is too long, i.e. more than 30 seconds, meaning that the fan blades continue to rotate for more than 30 seconds after they stop heating up, although this ensures that the heat stored in the fan blades is completely dissipated, the food temperature will be lower due to the prolonged rotation of the fan blades, affecting the taste of the food and increasing the user's waiting time, thus impacting the user experience.

[0102] In a specific embodiment, such as Figure 2 As shown, a control method for an air fryer is proposed, the control method including:

[0103] Step 202: The fan blades heat up and the motor drives them to rotate;

[0104] Step 204, at time T1, the fan blades stop heating up, and the motor continues to drive the rotation;

[0105] Step 206, at time T2, indicates that the entire machine has finished working and the motor has stopped.

[0106] In this embodiment, the operation ends at time T2, and the fan blades stop heating prematurely at time T1. The motor continues to drive the fan blades to rotate. At this time, the air will carry away the heat stored in the fan blades, which helps to maintain the temperature in the fryer. At the same time, it can also reduce the temperature of the fan blades themselves, thereby achieving energy saving and cooling of the fan blades.

[0107] The time interval from T1 to T2 is generally around 30 seconds, meaning the fan blades stop heating approximately 30 seconds in advance. T2 is the time displayed on the interface when the user indicates the end of the task, representing the total time the current function has been used.

[0108] In another specific embodiment, such as Figure 3 As shown, a control method for an air fryer is proposed, the control method including:

[0109] Step 302: The fan blades heat up and the motor drives them to rotate;

[0110] Step 304, at time T2, indicates that the entire machine has finished working, the fan blades have stopped heating, and the motor continues to drive the rotation;

[0111] In step 306, at time T1, the motor also stops rotating.

[0112] In this embodiment, at time T2, when the work is indicated to be finished, the fan blades stop heating up, but the motor continues to rotate to lower the fan blade temperature, continuing until time T1, when the motor also stops rotating. The duration from T1 to T2 is generally about 30 seconds, meaning that after the fan blades stop heating up, the motor continues to rotate the fan blades for about 30 seconds. Time T2 is the time when the user is notified on the display interface that the work is finished, which is the total time of the current function's operation.

[0113] This type of heat dissipation focuses more on reducing the temperature of the fan blades to prevent components such as the coil, motor, and power board from being damaged due to excessive temperature rise, thus extending the service life of the air fryer.

[0114] According to a second aspect of the present invention, a control device for an air fryer is provided. The air fryer includes a fan blade and a coil, the coil being opposite to the fan blade. The control device includes a processing unit, which controls the coil to be energized so that at least a portion of the fan blade heats up. The processing unit is also configured to de-energize the coil when the cooking time reaches a first duration, so that the fan blade stops heating up, and to control the fan blade to rotate for a second duration.

[0115] The air fryer provided in this embodiment of the invention includes a fan blade and a coil. The coil is opposite to the fan blade. Specifically, the coil can generate an alternating magnetic field when energized. The magnetically conductive fan blade heats up under the action of the alternating magnetic field, causing the temperature of the cooking cavity of the air fryer to rise rapidly. At the same time, the fan blade can also rotate inside the cooking cavity, quickly dissipating the heat generated by the fan blade, forming a hot airflow circulating inside the cooking cavity, thereby achieving the heating and cooking of the food inside the cooking cavity.

[0116] Understandably, the fan blades themselves generate heat and have a certain thickness. Furthermore, to ensure the heating power of the air fryer, the fan blades are generally quite thick, thus possessing a certain heat retention capacity. When cooking is complete and the air fryer stops working, the fan blades still maintain a high temperature. This high temperature can easily radiate to the air fryer's electronic control components, causing them to overheat and become damaged.

[0117] Once the first cooking time is reached, the control coil is de-energized to stop the fan from heating, but the fan continues to rotate for a second time. Specifically, the fan can be stopped heating and allowed to continue rotating during air fryer cooking, or it can be stopped heating and allowed to continue rotating after air fryer cooking is finished. The specific settings can be adjusted according to actual needs.

[0118] In other words, after the fan blades stop heating, they will continue to rotate for a second period of time. The fan blades stop heating and stop rotating at different times, which allows the heat stored in the fan blades to be fully dissipated. This effectively prevents the high-temperature fan blades from transferring heat to other electronic components after the air fryer stops working, thus preventing the electronic components from overheating and extending the service life of the entire machine.

[0119] Optionally, the first duration is equal to the cooking time. That is, when the machine finishes cooking and stops working, the fan blades continue to rotate for a second duration to dissipate its own heat.

[0120] Optionally, the first duration is shorter than the cooking time. That is, before the cooking is finished, the fan stops heating and continues to rotate for a second duration to dissipate its own heat.

[0121] Specifically, the first duration plus the second duration can equal the cooking time, meaning cooking ends immediately after the fan continues rotating for the second duration. Alternatively, the first duration plus the second duration can be greater than the cooking time, meaning cooking ends before the fan continues rotating for the second duration. Or, the first duration plus the second duration can be less than the cooking time, meaning cooking is not finished after the fan continues rotating for the second duration, and the coil is energized to reheat the fan. The specific settings can be configured according to actual needs.

[0122] In some embodiments, the air fryer may optionally include a motor connected to a fan blade, and the processing unit is specifically used to control the motor to run for a second duration.

[0123] In this embodiment, the air fryer is further defined as including a motor. Specifically, the motor is connected to the fan blades, meaning that the fan blades can rotate under the drive of the motor.

[0124] When the cooking time reaches the first set time, the control coil is powered off. At the same time, the motor drives the fan blades to continue rotating to fully dissipate the heat stored in the fan blades. This prevents the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control components when the machine is finished working, thus preventing them from being damaged due to excessive temperature rise. This extends the service life of the air fryer.

[0125] In some embodiments, the first duration may optionally be the total cooking time of the air fryer.

[0126] In this embodiment, the first duration is defined as the total cooking time of the air fryer. That is, when the cooking time of the air fryer reaches the first duration, the air fryer finishes its operation, that is, the food has been cooked and the whole machine stops working. At this time, the fan blades are controlled to continue rotating for a second duration to fully dissipate their stored heat and prevent the high temperature generated by the fan blades themselves from being transferred to the coil, motor, power board and other electronic control devices.

[0127] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting airflow allows the cooked food inside the cooking cavity to cool down evenly, resulting in a better overall appearance and ensuring the taste of the food.

[0128] For example, chicken wings need 15 minutes to bake, that is, the total cooking time is 15 minutes, or the first cooking time is 15 minutes.

[0129] In some embodiments, the first duration may be less than the total cooking time of the air fryer.

[0130] In this embodiment, the first duration is limited to less than the total cooking time of the air fryer. That is, before the entire machine finishes working, the fan blades stop heating and continue to rotate for a second duration to dissipate their own heat, thereby preventing the high temperature generated by the heat stored in the fan blades from being transferred to the coil, motor, power board and other electronic control devices.

[0131] In addition, as the fan blades continue to rotate and dissipate their stored heat, the resulting hot airflow can heat or assist in heating the food inside the cooking cavity, thereby shortening the heating time of the air fryer, which in turn shortens the heating time of the fan blades. This extends the lifespan of the air fryer while also saving energy.

[0132] For example, chicken wings need 15 minutes to bake, meaning the total cooking time is 15 minutes, with the first cooking time being 14 minutes, 13 minutes, or 12 minutes.

[0133] In some embodiments, optionally, the total cooking time t of the air fryer, the first time t1, and the second time t2 satisfy t = t1 + t2.

[0134] In this embodiment, the total cooking time of the air fryer is defined as the sum of the first and second cooking times. That is, when the cooking time reaches the first cooking time, the food in the cooking chamber has been cooked or is basically cooked. When the fan stops heating and continues to rotate for the second cooking time, the air fryer has finished working. This means that the air fryer's display interface will indicate to the user that the work is finished when the fan has rotated for the second cooking time.

[0135] For example, chicken wings need 15 minutes to bake, meaning the total cooking time is 15 minutes, with the first time being 14 minutes and 30 seconds and the second time being 30 seconds.

[0136] In some embodiments, the second duration t2 may optionally satisfy 5s≤t2≤30s.

[0137] In this embodiment, the second duration is limited to between 5 seconds and 30 seconds, so that when the fan blades stop heating, the heat of the fan blades themselves can be fully dissipated while ensuring the taste of the food, thereby improving the user experience.

[0138] Understandably, if the second duration is too short, i.e. less than 5 seconds, meaning that the fan blades continue to rotate for less than 5 seconds after they stop heating up, the heat stored in the fan blades cannot be completely dissipated, which can easily lead to a temperature rise in the electronic control components and affect the reliability of the air fryer.

[0139] If the second duration is too long, i.e. more than 30 seconds, meaning that the fan blades continue to rotate for more than 30 seconds after they stop heating up, although this ensures that the heat stored in the fan blades is completely dissipated, the food temperature will be lower due to the prolonged rotation of the fan blades, affecting the taste of the food and increasing the user's waiting time, thus impacting the user experience.

[0140] like Figure 4 As shown, according to a third aspect of the present invention, an air fryer control device 400 is provided, including a controller 402 and a memory 404, wherein the memory 404 stores a program or instructions, and the controller 402 implements the air fryer control method as described in any of the above embodiments when executing the program or instructions in the memory 404, thus possessing all the beneficial technical effects of the control method, which will not be elaborated here.

[0141] According to a fourth aspect of the present invention, a readable storage medium is provided, on which a program or instructions are stored. When the program or instructions are executed by a processor, they implement the control method of an air fryer as described in any of the above embodiments, and thus possess all the beneficial technical effects of the control method, which will not be elaborated further here.

[0142] According to a fifth aspect of the present invention, an air fryer 100 is provided, including a control device or readable storage medium for an air fryer as provided in any of the above embodiments, and thus possesses all the beneficial technical effects of the control device or readable storage medium for the air fryer, which will not be repeated here.

[0143] Optionally, such as Figure 5 , Figure 6 and Figure 7 As shown, the air fryer 100 includes a fan blade 110, a coil 120, a motor 130, and a cooking cavity 140. The coil 120 is opposite to the fan blade 110, the motor 130 is connected to the fan blade 110, and the fan blade 110 is located inside the cooking cavity 140.

[0144] Specifically, the coil 120 generates an alternating magnetic field when energized. The magnetically conductive fan blade 110 heats up under the action of the alternating magnetic field, causing the temperature of the cooking cavity 140 of the air fryer 100 to rise rapidly. At the same time, the motor 130 drives the fan blade 110 to rotate inside the cooking cavity 140, quickly dissipating the heat generated by the fan blade 110 and forming a hot airflow that circulates inside the cooking cavity 140, thereby heating and cooking the food inside the cooking cavity 140.
