Description

Technical Field

[0001] The present invention relates to the field of kitchen appliances, and in particular to an air fryer and a control method and electronic device thereof. Background Art

[0002] When the existing air fryer is used, the grease of the food will adhere to the fan, heat pipe and internal non-detachable structure with the hot air. After long-term use, a large amount of grease will accumulate. When the user uses it again, the hot air will heat the previously attached grease and make it evaporate onto the food, thereby causing secondary pollution and endangering health.

[0003] Therefore, how to design an air fryer that can remove grease attached to the fan, heat pipe and internal non-detachable structures to avoid secondary pollution has become a problem that needs to be solved urgently. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] Therefore, an object of the present invention is to provide a control method for an air fryer.

[0006] Another object of the present invention is to provide an air fryer.

[0007] A third object of the present invention is to provide an electronic device.

[0008] A fourth object of the present invention is to provide a computer-readable storage medium.

[0009] To achieve the above object, an embodiment of the first aspect of the present invention provides a control method for an air fryer, comprising:

[0010] After receiving the cleaning instruction, the operation of the fan assembly and the heating device is controlled according to the self-cleaning mode.

[0011] According to the control method of the air fryer provided by the embodiment of the present invention, after obtaining the cleaning instruction, the fan assembly and the heating device are controlled in the self-cleaning mode, so that after the air fryer has been used for a period of time, the air fryer can be self-cleaned through the self-cleaning mode of the air fryer, so that the grease attached to the heating device, the fan assembly and the internal non-detachable structure is heated and volatilized into the frying barrel, and then the user can clean the air fryer by cleaning the frying barrel. This setting can realize automatic cleaning of the air fryer through the self-cleaning mode, which solves the problem in the existing solution that the grease attached to the fan assembly, the heating device and the internal non-detachable structure of the air fryer is difficult to clean and easily causes secondary pollution. In this way, the cleanliness and hygiene of the air fryer during the cooking process are ensured.

[0012] Among them, the operation of controlling the fan assembly and the heating device according to the self-cleaning mode specifically includes:

[0013] Control the fan assembly and the heating device to work one or more times according to the preset steps; and control the speed of the fan assembly and the power of the heating device in each preset step, as well as the order in which the fan assembly and the heating device are turned on. Of course, it also includes the number of repetitions of the preset steps and the overall time of the preset steps. The setting of these parameters should be based on being able to fully heat and soften the oil stains on the air fryer to achieve the cleaning results we want. That is, the self-cleaning mode defines: the content of the preset steps, and the parameters required for the preset steps.

[0014] Furthermore, when the fan assembly and the heating device are controlled to work in the self-cleaning mode, the fan assembly and the heating device can be specifically controlled to be turned on and off according to a preset rule. When the fan assembly is turned on, the speed of the fan assembly is controlled, and when the heating device is turned on, the heating power of the heating device is controlled.

[0015] Furthermore, controlling the operation of the fan assembly and the heating device in the self-cleaning mode specifically includes: after obtaining the cleaning instruction, turning on the fan assembly and the heating device, after a first preset condition, stopping the heating device from heating, after a second preset condition, stopping the fan assembly, controlling the speed of the fan assembly when the fan assembly is turned on, and controlling the heating power of the heating device when the heating device is turned on.

[0016] In this technical solution, when the fan assembly and the heating device are controlled to work in the self-cleaning mode, the fan assembly and the heating device can be specifically controlled to open and close according to a preset rule. For example, the fan assembly and the heating device can be controlled to work simultaneously first, and after a first preset condition, such as a fixed time or the fan assembly continues to work, the heating device stops working, and after a second condition, the fan assembly stops working. The fan assembly and the heating device can quickly generate hot air and accelerate the flow of hot air when they work simultaneously at the beginning. After the hot air temperature meets certain conditions, the heating device can stop heating and only allow the hot air to flow, so that the hot air can continue to flow, so as to further soften the oil stains. Thereafter, the fan assembly can continue to move for a preset time and then stop. Among them, the first preset condition can be specifically that the hot air temperature is greater than or equal to the preset temperature range or the first preset condition can be specifically that the fan assembly and the heating device are turned on for a first time. The second preset condition can be that the fan assembly works independently for a second time or the hot air temperature is lower than the preset temperature value. The first time length and the second time length can be reasonably calculated through experiments based on the required temperature, the rotation speed of the fan assembly and the heating power of the heating device. At the same time, in this process, the rotation speed of the fan assembly and the power of the heating device can be reasonably controlled so that after the above time, the oil stains can be softened and the required cleaning effect can be achieved.

[0017] In the above technical solution, the steps of controlling the operation of the fan assembly and the heating device according to the self-cleaning mode specifically include:

[0018] The fan assembly and the heating device are controlled to work once or cyclically according to the preset steps. Further, the preset steps include: controlling the fan assembly and the heating device to work until the hot air temperature reaches a preset temperature range; after detecting that the hot air temperature reaches the preset temperature range, stabilizing the hot air temperature within the preset temperature range and continuing for a first preset time, and after the first preset time, stopping the heating device from heating and allowing the fan assembly to continue working for a second preset time.

[0019] In this technical solution, the self-cleaning mode of the air fryer includes: controlling the fan assembly and the heating device to work until the hot air temperature reaches the preset temperature range, and after the hot air temperature reaches the preset temperature range, stabilizing the temperature within the preset temperature range for the first preset time, and then stopping the heating device from heating, and allowing the fan assembly to continue working for the second preset time. After that, the above actions can be repeated as needed for a preset number of times to complete the entire cleaning process. Of course, the above cleaning process can also last only once without repeating. This setting can heat the hot air temperature to the preset temperature range and then circulate for a period of time so that the oil stains attached to the heating device, the fan assembly, etc. can be softened. After that, stopping the heating and allowing the fan assembly to continue working for the second preset time can bring the softened oil stains into the frying barrel through the flow of air, so as to achieve the separation of the oil stains from the heating device, the fan assembly, and other structures. By cycling the above cleaning steps, the self-cleaning of the air fryer can be made cleaner and the cleaning effect can be ensured.

[0020] Furthermore, the first preset time is 6 min-10 min, and the second preset time is 1 min-5 min.

[0021] In this embodiment, after the hot air temperature is heated to the preset temperature range, the heating device and the fan assembly continue to work and maintain the temperature within the preset temperature range for 6min-10min. Thereafter, the heating device stops heating and the fan assembly continues to work for 1min-5min. This setting can fully soften the oil stains after heating to a certain temperature, and the softened oil stains can be driven into the frying barrel under the circulation of air. In the actual process, the first preset time and the second preset time can be reasonably set as needed. It is not limited to 6min-10min and 1min-5min.

[0022] Furthermore, after obtaining the cleaning instruction, the fan assembly and the heating device are controlled to work 3-6 times according to preset steps.

[0023] In this technical solution, when the air fryer is self-cleaning, the number of times it works according to the preset steps should not be too many, otherwise the self-cleaning mode will be too long and the air fryer will dry burn and overheat. At the same time, the number of times it works according to the preset steps should not be too few, otherwise the cleaning efficiency will be low. In the actual process, the number of times the preset steps work in a cycle can be set to 3-6 times according to actual needs.

[0024] Furthermore, the preset temperature range is greater than or equal to 210° C. and less than or equal to 250° C.

[0025] In this technical solution, when the air fryer turns on the self-cleaning mode, the hot air temperature is heated to 210°C or less than 250°C, and then the temperature is maintained within this temperature range so that the oil stains can be heated until softened. This setting can fully soften the oil stains, thereby ensuring the cleaning effect. Of course, the preset temperature range can also be set to other values ​​as needed.

[0026] In any of the above technical solutions, the control method of the air fryer also includes: after determining that the air fryer meets the preset cleaning conditions, generating a cleaning prompt instruction, and after receiving the cleaning prompt instruction, controlling the prompt device to perform a cleaning prompt.

[0027] In these technical solutions, the air fryer is provided with preset cleaning conditions, and can judge whether the current cleaning index of the air fryer is greater than the preset index according to the use of the air fryer, and can generate a cleaning prompt instruction after judging that the air fryer meets the preset cleaning conditions, and provide cleaning prompts based on a sound prompt device, an indicator light, etc., so that after the user knows, the self-cleaning mode can be turned on to self-clean the air fryer. This setting enables the air fryer to self-judge whether it needs to be cleaned, and can remind the user in time, so that the user can clean it in time, avoiding the phenomenon that the user forgets to clean it after long-term use or the user cleans it frequently.

[0028] In a specific embodiment, the preset cleaning condition is that the cooking time re-counted after the air fryer was last enabled in the self-cleaning mode is greater than the preset time.

[0029] In this technical solution, after the air fryer turns on the cleaning mode, the cooking time of the air fryer can be recounted, and when the recounted cooking time of the air fryer is greater than the preset time, the user is reminded that it is time to clean. That is, this setting uses the cooking time after the last time the self-cleaning mode was turned on as the basis for whether the air fryer should be cleaned.

[0030] In another specific embodiment, the preset cleaning condition is that the number of cooking times re-counted since the air fryer last enabled the self-cleaning mode is greater than the preset number.

[0031] In this technical solution, after the air fryer turns on the cleaning mode, the cooking times of the air fryer can be recounted, and when the recounted cooking times of the air fryer are greater than the preset times, the user is reminded that it is time to clean. That is, this setting uses the cooking times since the last time the self-cleaning mode was turned on as the basis for whether the air fryer should be cleaned.

[0032] In another specific embodiment, the preset cleaning condition is that the total cooking times of the air fryer is n times the preset times, where n is an integer greater than or equal to 1, or the preset cleaning condition is that the total cooking time of the air fryer is m times the preset time, where m is an integer greater than or equal to 1.

[0033] In this technical solution, the user can be reminded that it is time to clean the air fryer after the cooking time of the air fryer reaches an integer multiple of the preset time or the cooking times of the air fryer reach an integer multiple of the preset times. That is, this setting determines whether the air fryer should be cleaned based on the total cooking time or the total cooking times of the air fryer.

[0034] In the fifth specific solution, the preset cleaning condition is that the number of times the air fryer takes out and puts in the frying bucket recounted since the last time the self-cleaning mode was enabled reaches the preset number of times. This setting can determine whether the air fryer can be cleaned by the number of times the frying bucket is taken out and put in.

[0035] In the sixth specific solution, the preset cleaning condition is that the thickness of the grease attached to the air fryer reaches a preset value. This setting can determine whether the air fryer can be cleaned by the thickness of the grease attached to the air fryer. For example, the thickness of the grease in the fan, heat pipe and internal parts can be detected.

[0036] In the seventh specific scheme, the preset cleaning condition is that the speed of the driving motor of the fan assembly has reached a preset value or a preset speed since the last time the self-cleaning mode was enabled. When the fan assembly is working, the motor that drives the fan to rotate is relatively clean on the surface of the fan when it is first used, and there is basically no oil stain. At this time, the driving motor only needs to drive the fan to rotate without additional load. After long-term use, the fan will form thicker oil stains due to the continuous accumulation of oil stains. At this time, it is equivalent to increasing the load of the driving motor, that is, the driving motor needs to drive the oil stains on the fan to rotate together in addition to driving the fan to rotate. This is like the fan is rotating with a load. Therefore, at this time, the speed of the driving motor will decrease due to the increase in the load. Based on this phenomenon, the amount of oil stains can be judged by the change in the speed of the driving motor, so as to determine whether the air fryer can be cleaned. This setting uses the change in the speed of the fan driving motor as the basis for whether the air fryer needs to be cleaned. The speed of the motor is relatively easy to detect, so it can make the detection and judgment of the preset cleaning conditions simpler and more convenient.

[0037] In addition, the preset condition may also be a combination of the above-mentioned conditions. By combining multiple conditions to determine whether the air fryer needs to be cleaned, the judgment result can be more accurate.

[0038] In any of the above technical solutions, the control method of the air fryer further includes: after the cleaning is completed, giving a prompt indicating that the cleaning is completed and / or giving a prompt indicating that the frying drum has been cleaned.

[0039] In this technical solution, after cleaning is completed, a prompt of cleaning completion and / or a prompt of cleaning the frying drum can be given, so that the user can be informed of the cleaning progress in time. At the same time, after the automatic cleaning of the air fryer is completed, the user can be reminded to clean the frying drum in time to prevent the oil stains from solidifying again in the frying drum.

[0040] In any of the above technical solutions, the control method of the air fryer also includes: when the power is turned on for the first time after cleaning, a reminder to clean the frying drum is given.

[0041] In this technical solution, a reminder to clean the frying drum is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying drum is given after the air fryer is cleaned. By giving the reminder to clean the frying drum after the first power-on, the user can be reminded again not to forget to clean the frying drum, thus avoiding the situation where the user forgets to clean the frying drum after the cleaning mode is enabled.

[0042] In any of the above technical solutions, the control method of the air fryer also includes: after obtaining the cleaning instruction, detecting and determining whether the current cleaning index of the air fryer is greater than or equal to the preset index, when the current cleaning index of the air fryer is greater than or equal to the preset index, controlling the operation of the fan assembly and the heating device in accordance with the self-cleaning mode, when the current cleaning index of the air fryer is less than the preset index, providing a prompt that no cleaning is required and / or detecting and determining whether the self-cleaning mode is received in a preset manner, and when the self-cleaning mode is received, controlling the operation of the fan assembly and the heating device in accordance with the self-cleaning mode, and ignoring the cleaning instruction when the self-cleaning mode is not received.

[0043] In this embodiment, after the cleaning instruction is detected, it is first detected and determined whether the current cleaning index of the air fryer is greater than the preset index. If so, it means that the cleaning index is high and normal cleaning can be performed. If not, it means that the air fryer is currently quite clean and does not need to be automatically cleaned. Then the preset steps can be executed, and the preset steps include: prompting that no cleaning is required in a preset manner. That is, after the user turns on the cleaning mode, if the current cleaning index of the air fryer is low, it means that the air fryer does not need to be cleaned, then the cleaning mode is not enabled, and the user is reminded in a pre-set manner that the air fryer does not need to be cleaned at present. The reminder method set in advance can be specifically that the cleaning button flashes with green light or the cleaning button is displayed with green light. On the contrary, if the air fryer determines that it needs to be cleaned by itself, it can be prompted by turning the cleaning button with red light. Of course, an indicator light can also be specially set for whether to perform a cleaning prompt, so that the indicator light can be used to specifically display the state of whether the air fryer needs to be cleaned.

[0044] Furthermore, the preset step also includes: detecting and determining whether a self-cleaning mode is received, and when the self-cleaning mode is received, controlling the operation of the fan assembly and the heating device according to the self-cleaning mode, and when the self-cleaning mode is not received, ignoring the cleaning instruction.

[0045] In this technical solution, after the user turns on the cleaning mode, if the current cleaning index of the air fryer is low, it means that the air fryer does not need to be cleaned. After that, it can be further detected and judged whether the air fryer has received the self-cleaning mode, such as long pressing the cleaning mode button, or turning off a certain indicator light at a preset frequency. Only after these self-cleaning modes are detected can it be said that the air fryer needs to be cleaned. If the self-cleaning mode is not detected, it means that the user accidentally touched or accidentally pressed the wrong button and did not really want to enable the cleaning mode, so the cleaning mode can be turned off. This setting can determine whether the air fryer needs to be cleaned according to the cleaning index after the user presses the cleaning mode. If necessary, it will be cleaned. If not, it will not be cleaned. This can avoid the air fryer from repeatedly turning on the cleaning mode, and can also avoid the user pressing the wrong cleaning mode button and enabling the cleaning mode in an inappropriate situation.

[0046] The current cleaning index of the air fryer is equal to the matching degree between the actual cleaning condition of the air fryer currently counted and the preset cleaning condition of the air fryer. The higher the matching degree, the more it needs to be cleaned, and the lower the matching degree, the less it needs to be cleaned. In this way, the matching degree can be used to roughly know whether the air fryer really needs to be cleaned, so as to avoid the air fryer from being cleaned repeatedly or the air fryer from being cleaned at the wrong time due to misoperation, such as too early or too late.

[0047] The technical solution of the second aspect of the present invention provides an air fryer, comprising: a heating device for heating air; a fan assembly for delivering the heated air into a cooking cavity; a processor and a memory, wherein a computer program is stored in the memory, and when the processor executes the computer program, the method provided in any one of the embodiments of the first aspect is implemented.

The memory stores a computer program, and when the processor executes the computer program, the method provided by any embodiment of the first aspect is implemented. In this way, the self-cleaning mode of the air fryer can be realized.

[0049] Furthermore, the air fryer also includes: a prompting device for prompting the frying barrel to be cleaned and / or prompting that the cleaning is completed.

[0050] In this technical solution, the air fryer also includes a prompting device, which can be specifically a sound prompting device, a light prompting device, a voice prompting device, etc. Through these prompting devices, the user can be reminded to clean the frying bucket in time.

[0065] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0066] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0067] Refer to the following Figures 1 to 7 The air fryer and control method thereof provided according to some embodiments of the present invention are described.

[0068] like Figure 1 As shown, an embodiment of the present invention provides a control method for an air fryer, comprising the following steps:

[0069] S102, detecting and determining whether a cleaning instruction is obtained.

[0070] S104, after obtaining the cleaning instruction, controlling the fan assembly and the heating device to operate in a self-cleaning mode.

[0071] According to the control method of the air fryer provided by the embodiment of the present invention, after obtaining the cleaning instruction, the fan assembly and the heating device can be controlled in the self-cleaning mode. In this way, after the air fryer has been used for a period of time, the air fryer can be self-cleaned through the self-cleaning mode of the air fryer, so that the grease attached to the heating device, the fan assembly and the internal non-detachable structure is heated and volatilized into the frying barrel. After that, the user can clean the air fryer by cleaning the frying barrel. This setting can realize automatic cleaning of the air fryer through the self-cleaning mode, which solves the problem in the existing solution that the grease attached to the fan assembly, the heating device and the internal non-detachable structure of the air fryer is difficult to clean and easily causes secondary pollution. In this way, the cleanliness and hygiene of the air fryer during the cooking process are ensured.

[0072] In the above embodiment, the control method of the air fryer further includes: prompting the user to clean the frying tub when the power is turned on for the first time after cleaning.

[0073] In these embodiments, a reminder to clean the frying tub is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying tub is given after the air fryer is cleaned. By giving a reminder to clean the frying tub after the first power-on, the user can be reminded again not to forget to clean the frying tub, thus avoiding the situation where the user forgets to clean the frying tub after the cleaning mode is enabled.

[0074] In the above embodiment, the control method of the air fryer further includes: after the cleaning is completed, prompting the user to clean the frying tub.

[0075] In this technical solution, after cleaning is completed, a prompt of cleaning completion and / or a prompt of cleaning the frying drum can be given, so that the user can be informed of the cleaning progress in time. At the same time, after the automatic cleaning of the air fryer is completed, the user can be reminded to clean the frying drum in time to prevent the oil stains from solidifying again in the frying drum.

[0076] Furthermore, when the fan assembly and the heating device are controlled to work in the self-cleaning mode, the fan assembly and the heating device can be specifically controlled to be turned on and off according to a preset rule. When the fan assembly is turned on, the speed of the fan assembly is controlled, and when the heating device is turned on, the heating power of the heating device is controlled.

[0077] Furthermore, controlling the operation of the fan assembly and the heating device in the self-cleaning mode specifically includes: after obtaining the cleaning instruction, turning on the fan assembly and the heating device, after a first preset condition, stopping the heating device from heating, after a second preset condition, stopping the fan assembly, controlling the speed of the fan assembly when the fan assembly is turned on, and controlling the heating power of the heating device when the heating device is turned on.

[0078] In this technical solution, when the fan assembly and the heating device are controlled to work in the self-cleaning mode, the fan assembly and the heating device can be specifically controlled to open and close according to a preset rule. For example, the fan assembly and the heating device can be controlled to work simultaneously, and after a first preset condition, such as a fixed time or the fan assembly continues to work, the heating device stops working, and after a second condition, the fan assembly stops working. The fan assembly and the heating device can quickly generate hot air and speed up the flow of hot air when they work simultaneously at the beginning. After the hot air temperature meets certain conditions, the heating device can stop heating and only let the hot air flow, so that the hot air can continue to flow so as to further soften the oil stains. Thereafter, the fan assembly can continue to move for a preset time and then stop.

[0079] The first preset condition may be that the hot air temperature is greater than or equal to the preset temperature range or the first preset condition may be that the fan assembly and the heating device are turned on for a first time. The second preset condition is that the fan assembly works independently for a second time.

[0080] The control method of the air fryer is further introduced below in conjunction with the following specific embodiments.

[0081] like Figure 2 As shown, embodiment 1 of the present invention provides a control method for an air fryer, comprising:

[0082] S202, generating a cleaning instruction according to the user's operation;

[0083] S204, after detecting the cleaning instruction, controlling the fan assembly and the heating device to work until the hot air temperature reaches a preset temperature range;

[0084] S206, after detecting that the hot air temperature reaches the preset temperature range, the hot air temperature is stabilized within the preset temperature range and lasts for a first preset time. After the first preset time, the heating device stops heating and the fan assembly continues to work for a second preset time.

[0085] In this embodiment, the self-cleaning mode of the air fryer includes: controlling the fan assembly and the heating device to work until the hot air temperature reaches a preset temperature range, and after the hot air temperature reaches the preset temperature range, stabilizing the temperature within the preset temperature range for a first preset time, and then stopping the heating device from heating, and allowing the fan assembly to continue to work for a second preset time. This setting can heat the hot air temperature to the preset temperature range and then circulate for a period of time, so that the oil stains attached to the heating device, the fan assembly, etc. can be softened, and then stopping the heating and allowing the fan assembly to continue to work for a second preset time can bring the softened oil stains into the frying drum through the flow of air, so as to achieve the separation of the oil stains from the heating device, the fan assembly, and other structures.

[0086] In the above embodiment, the control method of the air fryer further includes: providing a reminder for cleaning the frying drum when the power is turned on for the first time after cleaning is completed.

[0087] In these embodiments, a reminder to clean the frying tub is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying tub is given after the air fryer is cleaned. By giving a reminder to clean the frying tub after the first power-on, the user can be reminded again not to forget to clean the frying tub, thus avoiding the situation where the user forgets to clean the frying tub after the cleaning mode is enabled.

[0088] In a modified embodiment of the above embodiment 1, S204 and S206 may also be: after detecting the cleaning instruction, control the fan assembly and the heating device to work for a first duration. After the first duration, the heating device stops heating and the fan assembly continues to work for the first duration. In this embodiment, the fan assembly and the heating device are turned on and off mainly by time. The first duration and the second duration here can be reasonably calculated through experiments based on the required temperature, the rotation speed of the fan assembly and the heating power of the heating device.

[0089] like Figure 3 As shown, embodiment 2 of the present invention provides a control method for an air fryer, comprising:

[0090] S302: Generate a cleaning instruction according to the user's operation.

[0091] S304, controlling the fan assembly and the heating device to operate until the hot air temperature reaches a preset temperature range.

[0092] S306, after detecting that the hot air temperature reaches the preset temperature range, the hot air temperature is stabilized within the preset temperature range and lasts for a first preset time. After the first preset time, the heating device stops heating and the fan assembly continues to work for a second preset time.

[0093] S308, determine whether the number of cycles is greater than or equal to a preset value, if so, go to step S310, if not, go to step S304.

[0094] S310, prompting that the cleaning is completed and / or prompting to clean the frying vat.

[0095] In this embodiment, the self-cleaning mode of the air fryer includes: controlling the fan assembly and the heating device to work until the hot air temperature reaches a preset temperature range, and after the hot air temperature reaches the preset temperature range, stabilizing the temperature within the preset temperature range for a first preset time, and then stopping the heating device from heating, and allowing the fan assembly to continue working for a second preset time. The above actions can be repeated for a preset number of times to complete the entire cleaning process. This setting can heat the hot air temperature to a preset temperature range and then circulate for a period of time so that the oil stains attached to the heating device, the fan assembly, etc. can be softened. After that, stopping the heating and allowing the fan assembly to continue working for a second preset time can bring the softened oil stains into the frying barrel through the flow of air, thereby achieving the separation of the oil stains from the heating device, the fan assembly, and other structures. By cycling the above cleaning steps, the self-cleaning of the air fryer can be made cleaner and the cleaning effect can be ensured.

[0096] In the above embodiment, the fan assembly and the heating device are controlled to cycle 3 to 6 times, preferably not more than 5 times.

[0097] In this embodiment, when the air fryer is performing self-cleaning, the number of times the preset steps are performed should not be too many, otherwise the self-cleaning mode will be too long and the air fryer will dry burn and overheat. At the same time, the number of times the preset steps are performed should not be too few, otherwise the cleaning efficiency will be low. In the actual process, the number of times the preset steps are cycled can be set to 3-6 times according to actual needs.

[0098] In the above embodiment, after the air fryer is cleaned, a prompt to clean the frying tub is displayed when the air fryer is powered on for the first time.

[0099] In these embodiments, a reminder to clean the frying tub is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying tub is given after the air fryer is cleaned. By prompting the user to clean the frying tub again after the first power-on, the user can be reminded not to forget to clean the frying tub, thus avoiding the situation where the user forgets to clean the frying tub after the cleaning mode is enabled.

[0100] like Figure 4 As shown, embodiment 3 of the present invention provides a control method for an air fryer, comprising:

[0101] S400, determine whether the air fryer meets the preset cleaning conditions, if yes, go to S402, if not, go to S400.

[0102] S402, generating a cleaning prompt instruction, and performing a cleaning prompt after receiving the cleaning prompt instruction.

[0103] S404, determine whether a cleaning instruction is detected. If detected, go to S406. If not detected, go to S402.

[0104] S406, controlling the fan assembly and the heating device to operate until the hot air temperature reaches a preset temperature range.

[0105] S408, after detecting that the hot air temperature reaches the preset temperature range, the hot air temperature is stabilized within the preset temperature range and lasts for a first preset time. After the first preset time, the heating device stops heating and the fan assembly continues to work for a second preset time.

[0106] S410, determine whether the number of cycles is greater than or equal to a preset value. If so, go to S412, if less, go to step S406.

[0107] S412, prompts that the cleaning is completed, and prompts to clean the frying vat.

[0108] In this embodiment, the air fryer is provided with preset cleaning conditions, and can judge whether the current cleaning index of the air fryer is greater than the preset index according to the use of the air fryer, and can generate a cleaning prompt instruction after judging that the air fryer meets the preset cleaning conditions, and provide cleaning prompts based on a sound prompt device, an indicator light, etc., so that after the user knows, the self-cleaning mode can be turned on to self-clean the air fryer. This setting enables the air fryer to self-judge whether it needs to be cleaned, and can remind the user in time, so that the user can clean it in time, avoiding the phenomenon that the user forgets to clean it after using it for a long time or the user cleans it frequently. At the same time, this embodiment can also provide a prompt of cleaning completion and / or prompt to clean the frying barrel after cleaning is completed, so as to let the user know the cleaning progress in time. At the same time, it can also remind the user after the air fryer automatically cleans, so that the user can clean the frying barrel in time to avoid the oil stains solidifying in the frying barrel again.

[0109] In a specific solution, the preset cleaning condition in S400 is that the cooking time re-counted since the cleaning mode of the air fryer was last enabled is greater than the preset time.

[0110] In this embodiment, after the air fryer turns on the cleaning mode, the cooking time of the air fryer can be recounted, and when the recounted cooking time of the air fryer is greater than the preset time, the user is reminded that it is time to clean. That is, this setting uses the cooking time after the last time the self-cleaning mode was turned on as the basis for whether the air fryer should be cleaned.

[0111] In another specific embodiment, the preset cleaning condition in S400 is that the number of cooking times re-counted by the air fryer since the last time the self-cleaning mode was enabled is greater than the preset number.

[0112] In this embodiment, after the air fryer turns on the cleaning mode, the cooking times of the air fryer can be recounted, and when the recounted cooking times of the air fryer are greater than the preset times, the user is reminded that it is time to clean. That is, this setting uses the cooking times since the last time the self-cleaning mode was turned on as the basis for whether the air fryer should be cleaned.

[0113] In another specific embodiment, the preset cleaning condition in S400 is that the total number of cooking times of the air fryer is an integer multiple of the preset number of times.

[0114] In another embodiment, the preset cleaning condition in S400 is that the total cooking time of the air fryer is an integer multiple of the preset time.

[0115] In this embodiment, the user can be reminded that it is time to clean the air fryer after the cooking time of the air fryer reaches an integer multiple of the preset time or the cooking times of the air fryer reach an integer multiple of the preset times. That is, this setting determines whether the air fryer should be cleaned based on the total cooking time or the total cooking times of the air fryer.

[0116] In the fifth specific solution, the cleaning condition preset in S400 is that the number of times the air fryer has been taken out and put back since the self-cleaning mode was last enabled reaches the preset number of times. This setting can determine whether the air fryer can be cleaned by the number of times the air fryer has been taken out and put back.

[0117] In the sixth specific solution, the cleaning condition preset in S400 is that the thickness of the grease attached to the air fryer reaches a preset value. This setting can determine whether the air fryer can be cleaned by the thickness of the grease attached to the air fryer. For example, the thickness of the grease in the fan, heat pipe and internal parts can be detected.

[0118] In addition, the cleaning condition preset in S400 may also be a combination of the above-mentioned conditions. By combining multiple conditions to determine whether the air fryer needs to be cleaned, the judgment result can be more accurate.

[0119] In the seventh specific scheme, the cleaning condition preset in S400 is that the speed of the driving motor of the fan assembly has reached a preset value or a preset speed since the last time the self-cleaning mode was enabled. When the fan assembly is working, the motor that drives the fan to rotate is relatively clean on the surface of the fan when it is first used, and there is basically no oil stain. At this time, the driving motor only needs to drive the fan to rotate without additional load. After long-term use, the fan will form thicker oil stains due to the continuous accumulation of oil stains. At this time, it is equivalent to increasing the load of the driving motor, that is, the driving motor needs to drive the oil stains on the fan to rotate together in addition to driving the fan to rotate. This is like the fan is rotating under load. Therefore, at this time, the speed of the driving motor will decrease due to the increase in load. Based on this phenomenon, the amount of oil stains can be judged by the change in the speed of the driving motor, so as to determine whether the air fryer can be cleaned. This setting uses the change in the speed of the fan driving motor as the basis for whether the air fryer needs to be cleaned. The speed of the motor is relatively easy to detect, so it can make the detection and judgment of the preset cleaning conditions simpler and more convenient.

[0120] In the above embodiment, the control method of the air fryer also includes prompting to clean the frying tub after cleaning is completed and when the power is turned on for the first time.

[0121] In these embodiments, a reminder to clean the frying tub is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying tub is given after the air fryer is cleaned. By prompting the user to clean the frying tub again after the first power-on, the user can be reminded not to forget to clean the frying tub, thus avoiding the situation where the user forgets to clean the frying tub after the cleaning mode is enabled.

[0122] like Figure 5 As shown, embodiment 4 of the present invention provides a control method for an air fryer, comprising:

[0123] S500, after obtaining the cleaning instruction, detect and determine whether the current cleaning index of the air fryer is greater than or equal to the preset index. If it is greater than or equal to, go to S502, if it is less than, go to S504.

[0124] S502, controlling the fan assembly and the heating device to operate in a self-cleaning mode.

[0125] S504, providing a no-cleaning reminder in a pre-set manner.

[0126] S506, detect and determine whether a preset operation is received, if so, go to S502, if not, go to S508.

[0127] S508 Ignore the cleaning instruction.

[0128] In this embodiment, after the cleaning instruction is detected, it is first detected and determined whether the current cleaning index of the air fryer is greater than the preset index. If so, it means that the cleaning index is high and normal cleaning can be performed. If not, it means that the air fryer is currently quite clean and does not need to be automatically cleaned. Then the preset steps can be executed, and the preset steps include: prompting that no cleaning is required in a preset manner. That is, after the user turns on the cleaning mode, if the current cleaning index of the air fryer is low, it means that the air fryer does not need to be cleaned, then the cleaning mode is not enabled, and the user is reminded in a pre-set manner that the air fryer does not need to be cleaned at present. The reminder method set in advance can be specifically that the cleaning button flashes with green light or the cleaning button is displayed with green light. On the contrary, if the air fryer determines that it needs to be cleaned by itself, it can be prompted by turning the cleaning button with red light. Of course, an indicator light for whether to perform a cleaning prompt can also be specially set to specifically display the state of whether the air fryer needs to be cleaned through the indicator light. At the same time, in this embodiment, after the user turns on the cleaning mode, if the current cleaning index of the air fryer is low, it means that the air fryer does not need to be cleaned. After that, it can be further detected and determined whether the air fryer has received the self-cleaning mode, such as long pressing the cleaning mode button, or turning off a certain indicator light at a preset frequency. Only after these self-cleaning modes are detected can it be said that the air fryer needs to be cleaned. If the self-cleaning mode is not detected, it means that the user has touched it by mistake or accidentally pressed the wrong button, and does not really want to enable the cleaning mode, so the cleaning mode can be turned off. This setting can determine whether the air fryer needs to be cleaned based on the cleaning index after the user presses the cleaning mode. If necessary, it will be cleaned. If not, it will not be cleaned. This can avoid the air fryer from repeatedly turning on the cleaning mode, and can also avoid the user pressing the wrong cleaning mode button and enabling the cleaning mode in an inappropriate situation.

[0129] The current cleaning index of the air fryer is equal to the matching degree between the actual cleaning condition of the air fryer currently counted and the preset cleaning condition of the air fryer. The higher the matching degree, the more it is desired to clean it, and the higher the matching degree, the less it is desired to clean it. In this way, the matching degree can be used to roughly know whether the air fryer really needs to be cleaned, so as to avoid the air fryer from being cleaned repeatedly or the air fryer from being cleaned at the wrong time due to misoperation, such as too early or too late.

[0130] In the above embodiment, the control method of the air fryer further includes: after cleaning is completed and when the power is turned on for the first time, a prompt to clean the frying tub is provided.

[0131] In these embodiments, a reminder to clean the frying tub is given when the air fryer is powered on for the first time after the self-cleaning mode is turned on. Because the self-cleaning mode of the air fryer is relatively long, the user may not be at home when the reminder to clean the frying tub is given after the air fryer is cleaned. By prompting the user to clean the frying tub again after the first power-on, the user can be reminded not to forget to clean the frying tub, thus avoiding the situation where the user forgets to clean the frying tub after the cleaning mode is enabled.

[0132] In any of the above embodiments, the first preset time is greater than or equal to 6 minutes and less than or equal to 10 minutes, and the second preset time is greater than or equal to 1 minute and less than or equal to 5 minutes.

[0133] In this embodiment, after the hot air temperature is heated to the preset temperature range, the heating device and the fan assembly continue to work and maintain the temperature within the preset temperature range for 6 minutes to 10 minutes. Thereafter, the heating device stops heating and the fan assembly continues to work for 1 minute to 5 minutes. This arrangement can fully soften the oil stains after heating to a certain temperature, and the softened oil stains can be driven into the frying barrel under the circulation of air.

[0134] In any of the above embodiments, the preset temperature range is 210° C.-250° C. Further, the temperature may be around 220° C.

[0135] In this embodiment, when the air fryer turns on the self-cleaning mode, after the hot air temperature is heated to 210°C or less than 250°C, the temperature is maintained within the temperature range so that the oil stains can be heated until softened. This setting can fully soften the oil stains, thereby ensuring the cleaning effect. Of course, the preset temperature range can also be set to other values ​​as needed.

[0136] Based on the above embodiments and preferred parameters, a control method for an air fryer is provided. Figure 6 As shown, the method comprises the following steps:

[0137] S600, detecting and determining whether a cleaning instruction is generated, if so, going to step 602;

[0138] S602, controlling the fan assembly and the heating device to work until the hot air temperature reaches about 230°C;

[0139] S604, stabilize the hot air temperature at about 230°C for 6-10 minutes, then stop the heating device and continue the fan assembly to work for 1-5 minutes;

[0140] S606, determine whether the number of cycles is greater than or equal to 5, if it is greater, go to step S608, if it is less than, go to step S602;

[0141] S608, a prompt is given to indicate that the cleaning is completed, and a prompt is given to indicate that the frying drum is cleaned.

[0142] In this embodiment, when the cleaning mode is turned on, the hot air temperature can be heated to about 230°C and circulated for a period of time to soften the oil stains attached to the heating device, the fan assembly, etc., and then the heating is stopped and the fan assembly is allowed to continue to work for 1-5 minutes to bring the softened oil stains into the frying drum through the flow of air, so that the oil stains and the heating device, the fan assembly, etc. can be separated. Through the five cycles of cleaning steps, the self-cleaning of the air fryer can be made cleaner and the cleaning effect can be ensured.

[0143] Furthermore, the time for stopping heating and allowing the fan assembly to continue working is preferably about 2 minutes.

[0144] Furthermore, after the hot air temperature is heated to about 230° C., the fan assembly and the heating device continue to work for about 8 minutes.
