Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Example 1

In accordance with an embodiment of the present invention, there is provided a method of controlling an air fryer, it being noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.

FIG. 1 is a flow chart of a method of controlling an air fryer, according to an embodiment of the present invention, as shown in FIG. 1, the method comprising the steps of:

step S102, determining the food material amount of the cooking food material in the process of cooking the cooking food material by the air fryer.

The cooking food material in the above steps may be a food material that needs to be manually turned by a user during the cooking process, for example, but not limited to, french fries. The amount of the food material in the above steps may refer to the amount of the food material to be cooked, and may be a range of numerical values, and need not be precise to be a specific numerical value.

In the process of cooking the cooking food materials by the air fryer, the quantity of the food materials put into the air fryer by a user is different, the temperature rising rates of the food materials at different positions are different, the smaller the quantity of the food materials is, the smaller the temperature difference between the food materials positioned above and the food materials positioned below is, and the longer the cooking time is, the more easily the bottom food materials are scorched; the larger the food quantity is, the larger the temperature difference between the upper food and the lower food is, the shorter the cooking time is, and the more easily the top food is half-cooked. Therefore, there is a need to determine the amount of material cooked during the cooking process.

In an alternative embodiment, the amount of material cooked may be measured in a number of ways, for example, by a weighing sensor that captures the weight of the material cooked, for example, by a camera that captures an image of the material cooked, determining the amount of material in conjunction with the size of the fry vat, and for example, directly determining the amount of material by detecting the temperature difference between the upper and lower temperatures of the material cooked. In order to reduce the detection cost, in the embodiment of the present invention, the temperature detection is taken as an example for description.

And step S104, outputting prompt information according to a prompt mode corresponding to the food material quantity, wherein the prompt information is used for prompting the turning of the cooking food materials.

The prompting method in the above steps may include, but is not limited to, a time for outputting the prompting message and a number of times for outputting the prompting message.

In order to obtain a better cooking effect, the larger the amount of the food materials is, the longer the cooking time is, and the user turns over the cooking food materials for many times; the smaller the amount of food material, the shorter the cooking time is often required, and the user needs to turn over the cooking material many times. Therefore, different prompt modes can be determined based on different food material quantities, prompt information can be output according to the determined prompt modes, and a user can turn over the cooked food materials in time according to the prompt information conveniently.

It should be noted that the output method of the prompt message may be to display text messages on the display screen of the air fryer, or to play voice messages through a voice playing device such as a speaker installed on the air fryer, or to send the voice messages to the mobile terminal of the user through a wireless network, and the mobile terminal prompts the messages.

Optionally, in the foregoing embodiment of the present invention, in step S102, the determining the food material amount of the cooking food material includes: acquiring the upper temperature and the lower temperature of a cooking cavity of the air fryer; based on the temperature difference of the upper temperature and the lower temperature, the food material amount of the cooking food material is determined.

The top of the existing air fryer is provided with an NTC (Negative Temperature Coefficient thermistor), so that the upper Temperature can be collected through the NTC at the top. In order to accurately acquire the lower temperature, a temperature probe can be prepared in advance, and the lower temperature can be acquired through the temperature probe, wherein the lower temperature can refer to the temperature of the bottom of the food material, and can also refer to the temperature of the upper part of the food material (namely the temperature of the middle part of the cooking cavity).

The upper temperature is basically not influenced by the amount of food materials, a relatively closed state is presented in the heating process, and a fixed rule is provided under the condition that the structural parameters are fixed. The lower temperature is affected by the amount of food material, and the lower temperature rises more slowly as the amount of food material increases, and rises more rapidly as the amount of food material decreases. Therefore, the temperature difference between the upper temperature and the lower temperature can be used as a basis for judging the amount of the food material, and the larger the temperature difference is, the larger the amount of the food material is.

For example, as shown in fig. 2a and 2b, for 300g of french fries and 500g of french fries, the two temperature difference curves are substantially the same and less different for a period of time after cooking has begun, e.g., for the first 3 minutes (as shown by the curves before the dashed line in fig. 2a and 2 b); after cooking for 3 minutes, the temperature difference of 300g of french fries is maintained substantially at 70 ℃ as shown in fig. 2 a; as shown in fig. 2b, the temperature difference for 500g of french fries exceeds 70 ℃. On the basis, the temperature difference is larger for larger food material quantity, so that the food material quantity of the cooked food material can be determined through the temperature difference.

Optionally, in the above embodiment of the present invention, determining the amount of the material cooked based on the temperature difference between the upper temperature and the lower temperature includes: acquiring a plurality of preset temperature intervals, wherein the preset food material amount corresponding to different preset temperature intervals is different; comparing the temperature difference with a plurality of preset temperature intervals, and determining a target temperature interval to which the temperature difference belongs; and determining the preset food material amount corresponding to the target temperature interval as the food material amount of the cooking food material.

In order to achieve the purpose of accurately determining the food material quantity based on the temperature difference, the food material quantity can be divided into several grades, and corresponding temperature difference values are determined in advance through experiments aiming at different grades, so that temperature intervals corresponding to different grades are obtained. The temperature difference is compared with a plurality of temperature intervals, which may be comparing the temperature difference with the minimum value and the maximum value of each temperature interval, and if the temperature difference is greater than the minimum value of one temperature interval and less than the maximum value of the temperature interval, it is determined that the temperature difference belongs to the temperature interval, that is, the temperature interval is the target temperature interval.

It should be noted that, because the types of the cooking food materials are different, the types, the sizes and the like of the air fryer are different, and the influence on the collected temperature is different, in an actual process, the corresponding relationship between different levels of the food material amount and the preset temperature interval can be determined for different types of cooking food materials in advance through experiments for different air fryers.

In an alternative embodiment, two temperature difference thresholds may be preset, namely y1 and y2, wherein y1> y2, and at this time, the corresponding three temperature interval ratios may be considered as: greater than y1, less than y1 and greater than y2, and less than y2, corresponding to more, normal and less food material amounts, respectively. After the temperature difference Δ t between the upper temperature and the lower temperature is obtained, Δ t may be compared with y1 and y2, respectively, and if Δ t < y2, it may be determined that Δ t belongs to a temperature interval "less than y 2" and the corresponding amount of food material is small; if y2< Δ t < y1, it may be determined that Δ t belongs to a temperature interval "less than y1 and greater than y 2" and the corresponding amount of food material is normal; if Δ t > y1, it can be determined that the corresponding food material amount is large in the temperature interval of "greater than y 1".

For example, as shown in fig. 2a and 2b, taking the food material amount divided into two levels of 300g and 500g as an example, a temperature difference threshold may be preset, and the temperature difference threshold may be a temperature value of 70-73 ℃, so that two preset temperature intervals may be determined by the temperature difference threshold. For example, when the temperature threshold is 70 ℃, 300g of the corresponding preset temperature interval is greater than 60 ℃ and less than 70 ℃; the preset temperature interval corresponding to 500g is more than or equal to 70 ℃ and less than 90 ℃. When the temperature threshold is 71 ℃, the corresponding preset temperature interval of 300g is more than 60 ℃ and less than 71 ℃; the preset temperature interval corresponding to 500g is greater than or equal to 71 ℃ and less than 90 ℃. When the temperature threshold is 72 ℃, the corresponding preset temperature interval of 300g is more than 60 ℃ and less than 72 ℃; the preset temperature interval corresponding to 500g is greater than or equal to 72 ℃ and less than 90 ℃. When the temperature threshold is 73 ℃, the corresponding preset temperature interval of 300g is more than 60 ℃ and less than 73 ℃; the preset temperature interval corresponding to 500g is greater than or equal to 73 ℃ and less than 90 ℃. The specific correspondence is shown in table 1:

TABLE 1

For example, after the upper and lower temperatures are detected, if the temperature difference between the upper and lower temperatures is 76 ℃, that is, within the range of the preset temperature interval [70, 90 ], it may be determined that the amount of the food material is 500 g; if the temperature difference between the upper temperature and the lower temperature is 68 ℃, that is, within the range of the preset temperature interval (60, 70), it may be determined that the amount of the food material is 300 g.

For example, after the upper and lower temperatures are detected, if the temperature difference between the upper and lower temperatures is 76 ℃, that is, within the range of the preset temperature interval [71, 90 ], it may be determined that the amount of the food material is 500 g; if the temperature difference between the upper temperature and the lower temperature is 68 ℃, that is, within the range of the preset temperature interval (60, 71), it may be determined that the amount of the food material is 300 g.

For example, after the upper and lower temperatures are detected, if the temperature difference between the upper and lower temperatures is 76 ℃, that is, within the range of the preset temperature interval [72, 90 ], it may be determined that the amount of the food material is 500 g; if the temperature difference between the upper temperature and the lower temperature is 68 ℃, i.e., within the range of the preset temperature interval (60, 72), it may be determined that the amount of the food material is 300 g.

For example, after the upper and lower temperatures are detected, if the temperature difference between the upper and lower temperatures is 76 ℃, that is, within the range of the preset temperature interval [73, 90 ], it may be determined that the amount of the food material is 500 g; if the temperature difference between the upper temperature and the lower temperature is 68 ℃, i.e., within the range of the preset temperature interval (60, 73), it may be determined that the amount of the food material is 300 g.

Optionally, in the foregoing embodiment of the present invention, in step S104, outputting the prompt information according to the prompt mode corresponding to the food material amount includes: determining prompting time and prompting times in a prompting mode based on the food material quantity, wherein the prompting time and/or the prompting times corresponding to different food quantities are different; and outputting prompt information according to the prompt times when the timing time reaches the prompt time.

The prompt time in the above steps may refer to the time of continuing to wait, that is, the waiting time before outputting the prompt information; the number of times of prompting may be the number of times the user is required to turn over the cooking ingredients, and outputting the one-time prompting information requires the user to turn over the cooking ingredients once.

The larger the amount of food material is, the longer time is needed for cooking the food material, and the more times the user turns over the food material, that is, the longer the prompting time is, and the more times the prompting is. Therefore, the corresponding prompting time and prompting times can be set in advance according to the food material quantities of different grades. For example, taking the food material amount divided into two grades of 300g and 500g as an example, the prompting time and the prompting frequency corresponding to different food material amounts are shown in the following table 2, where T represents the cooking time of the cooking:

TABLE 2

Amount of food (g)	Time of presentation	Number of times of presentation
			300	T/2	1
500	T/2～3T/4	2

In an optional embodiment, a repeated prompting mode can be adopted, and the step of outputting the prompting information for multiple times is executed in a circulating manner, so that the prompting time and the prompting times are determined according to the food material quantity, a user is ensured to turn over for multiple times at different time according to different food material quantities, and the purpose of improving the cooking effect is further achieved.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food is determined to be 300g, outputting prompt information to prompt a user to turn over the cooked food after the timing time reaches 15 minutes; when the amount of the food material to be cooked is 500g, the prompt information may be output after 15 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information may be output again after waiting for a period of time to prompt the user to turn over the cooking food material.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food is determined to be 300g, outputting prompt information to prompt a user to turn over the cooked food after the timing time reaches 15 minutes; when the amount of the food material to be cooked is determined to be 500g, the prompt information can be output after 19 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information can be output again after waiting for a period of time to prompt the user to turn over the cooking food material.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food is determined to be 300g, outputting prompt information to prompt a user to turn over the cooked food after the timing time reaches 15 minutes; when the amount of the food material currently cooked is determined to be 500g, the prompt information can be output after 22 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information can be output again after waiting for a period of time to prompt the user to turn over the cooking food material.

Optionally, in the foregoing embodiment of the present invention, outputting the prompt information according to the number of prompts includes: outputting prompt information under the condition that the timing time reaches a first preset time; detecting whether the cooking food materials are turned over successfully or not; if the cooking food materials are successfully turned over, increasing the output times of the prompt information; judging whether the output times reach the prompting times or not; and if the output times do not reach the prompting times, restarting timing, and returning to the step of outputting the prompting information under the condition that the timing time reaches the first preset time until the output times reach the prompting times.

The first preset time of the above steps is used to represent the waiting time before the prompt information is output, different values may be set for the food material amounts of different levels, the same value may also be adopted, and the setting may be performed according to actual needs, for example, the first preset time may be 2 minutes under the condition that the same value is adopted.

In an optional embodiment, when the timed time reaches the first preset time, outputting a prompt message to prompt the user to turn over the cooking food material, and detecting whether the user turns over the cooking food material, if so, adding 1 to the output frequency, where the output frequency is initially 0, the output frequency is 1 at this time, and if the prompt frequency is 3, that is, the output frequency is less than the prompt frequency, returning to continue to wait for the timed time to reach the first preset time. And under the condition that the timing time reaches the first preset time, outputting the prompt information again to prompt the user to turn over the cooked food materials, and detecting whether the user turns over the cooked food materials, if so, adding 1 to the output frequency, wherein the output frequency is 2, the output frequency is less than the prompt frequency, and returning to continuously wait for the timing time to reach the first preset time. And under the condition that the timing time reaches the first preset time, outputting prompt information again to prompt the user to turn over the cooking food materials, and detecting whether the user turns over the cooking food materials, wherein if so, the output frequency can be increased by 1, at the moment, the output frequency is 3, the output frequency is equal to the prompt frequency, and the fact that the operation of prompting the user to turn over the cooking food materials is finished is determined, and the user does not need to turn over the food materials again. The user is repeatedly prompted to turn over the cooking food materials for a plurality of times, so that the user turns over the cooking food materials once every certain time interval, and the purpose of improving the cooking effect is further achieved.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food is determined to be 300g, outputting prompt information to prompt a user to turn over the cooked food after the timing time reaches 15 minutes; when the amount of the food material to be cooked is determined to be 500g, the prompt information can be output after 15 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information is output again after waiting for 2 minutes to prompt the user to turn over the cooking food material.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food materials is 300g, outputting prompt information to prompt a user to turn over the cooked food materials after the timing time reaches 15 minutes; when the amount of the food material to be cooked is determined to be 500g, the prompt information can be output after 19 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information is output again after waiting for 2 minutes to prompt the user to turn over the cooking food material.

For example, assume that the user sets the cooking time period for this cooking to 30 minutes before starting the cooking. When the amount of the currently cooked food is determined to be 300g, outputting prompt information to prompt a user to turn over the cooked food after the timing time reaches 15 minutes; when the amount of the food material to be cooked is determined to be 500g, the prompt information may be output after 22 minutes to prompt the user to turn over the cooking food material, and after the user turns over the cooking food material, the prompt information may be output again after waiting for 2 minutes to prompt the user to turn over the cooking food material.

Optionally, in the above embodiment of the present invention, the detecting whether the turning of the cooking food material is successful includes one of: detecting the state of the micro switch, wherein when the state of the micro switch is in a first state, the cooking food materials are determined to be turned over successfully, and when the state of the micro switch is in a second state, the cooking food materials are determined to be not turned over successfully; and detecting whether a confirmation signal generated by the target key is received, wherein the cooking food materials are determined to be turned over successfully under the condition that the confirmation signal is received, and the cooking food materials are determined to be turned over unsuccessfully under the condition that the confirmation signal is not received.

In order to achieve the purpose of detecting whether the user turns over the cooking food materials, the detection can be realized by detecting a microswitch or a target key for confirmation. In an alternative embodiment, the detecting of the micro switch may be performed by detecting the state of the micro switch and presetting the flipping results corresponding to different states, for example, the first state corresponds to flipping, and the second state corresponds to not flipping. In another alternative embodiment, the user may press the target key after turning the cooking food material by detecting the confirmation of the target key, and the target key generates the confirmation signal, so that it may be determined that the confirmation signal is received as turned and the confirmation signal is not received as turned.

Optionally, in the above embodiment of the present invention, if the cooking food material is not successfully flipped, the timing is restarted, and the step of outputting the prompt information is returned to be executed when the timing time reaches the first preset time, until the cooking food material is successfully flipped.

In an optional embodiment, if the user does not turn over the cooking food materials after the prompt information is output, the timing is returned to be restarted, the prompt information is output again under the condition that the first preset time is reached again, the user is waited to turn over the cooking food materials, and if the user turns over the cooking food materials, the output frequency can be increased by 1; and if the user does not turn over the cooked food materials, timing again and waiting for outputting the prompt information again. The user is ensured to turn over the cooking food material at a proper time by repeatedly prompting the user, and the purpose of improving the cooking effect is further achieved.

Optionally, in the above embodiment of the present invention, the upper temperature and the lower temperature are acquired when the cooking time of the air fryer to cook the cooking food material reaches the second preset time.

For an air fryer, the time for the top NTC to rise to the temperature control point is typically around 3 minutes, for example, as shown in FIGS. 2a and 2b, after cooking for 3 minutes, there is an increasing difference between the temperature difference of 300 grams of french fries and the temperature difference of 500 grams of french fries. Therefore, the second predetermined time in the above step may be slightly less than this time, that is, the second predetermined time is approximately 3 minutes.

In an alternative embodiment, the timer is started when the air fryer starts to cook, and when the timer reaches a second preset time, the upper temperature collected by the top NTC and the lower temperature collected by the temperature probe are read to determine the temperature difference. The temperature difference between the upper temperature and the lower temperature is obtained after cooking for a period of time, so that the aim of accurately determining the amount of the food material is fulfilled.

Optionally, in the above embodiment of the present invention, acquiring the upper temperature and the lower temperature includes: acquiring the upper temperature acquired by a temperature sensor, wherein the temperature sensor is arranged at the top of the air fryer; acquiring the lower temperature acquired by the temperature probe, wherein the temperature probe is placed at the bottom of a frying column of the air fryer before the air fryer starts to cook the cooking food material.

The temperature sensor in the above step may be a top NTC already existing in the air fryer, and the temperature probe may be a temperature probe prepared in advance for a user, and when the user needs to cook food materials such as french fries, the user needs to place the temperature probe at the bottom of the fry vat in advance, so that the lower temperature can be collected. The temperature sensor is arranged on the top of the air fryer in advance, and the temperature probe is arranged at the bottom of the frying fence of the air fryer, so that the aim of detecting the upper temperature and the lower temperature is fulfilled.

Optionally, in the above embodiment of the present invention, after determining the food material amount of the cooking food material, the method further includes: acquiring cooking parameters of the air fryer; judging whether the cooking parameters are matched with the food material quantity; if the matching of the cooking parameters and the food material quantity fails, acquiring target cooking parameters corresponding to the food material quantity; and outputting the target cooking parameters.

The cooking parameters in the above steps may be parameters that may be affected by the amount of the food, such as cooking time and cooking temperature, and the cooking time is taken as an example in the embodiment of the present invention for description.

In an optional embodiment, after the food material amount is determined, when the user selects a cooking parameter unsuitable for the current food material amount, the user is pushed a suitable cooking parameter, so that the purpose of improving the cooking effect is further achieved.

A preferred embodiment of the present invention will now be described in detail with reference to fig. 3 and 4, taking the air fryer for french fries as an example.

As shown in fig. 3, the method comprises the steps of: placing a temperature probe at the bottom of the fry vat, placing the french fries, selecting french fries functionality and starting cooking, running for a period of time t1 (i.e., the second predetermined time described above), reading the top NTC temperature Temp1 (i.e., the upper temperature described above) and the probe temperature Temp2 (i.e., the lower temperature described above). Further judging whether Temp1-Temp2 is larger than y1, if Temp1-Temp2> y1, timing t2 time (namely the prompting time), prompting the user to turn over the potato chips, and repeatedly prompting for a times (namely the prompting times); if Temp1-Temp2< y1, further judging whether Temp1-Temp2 is larger than y2, if Temp1-Temp2> y2, timing t3 time (namely the prompting time), prompting the user to turn over the potato chips, and prompting for b times (namely the prompting times); if Temp1-Temp2< y2, a time t4 is timed (i.e., the prompt time mentioned above) to prompt the user to turn the potato chips, where the number of prompts is 1.

As shown in fig. 4, the repeated prompting process is as follows: starting timing, prompting a user to turn over the potato chips when the preset time (namely the first preset time) is reached, judging whether the user turns over the potato chips, if not, returning to the timing again, if so, counting the increase of Times, and judging whether the Times is more than the required repetition Times (namely the prompting Times), such as a Times, b Times and the like, and if not, returning to the timing again; if so, determining that the repeated prompting process is completed.

Optionally, the t2> t3> t4 are adopted, that is, the larger the food material amount is, the longer the time is; y1> y 2.

Through the scheme, the temperature probe can be combined with the top NTC to judge the food material amount and the current cooking state of the cooking food material, and the user is prompted according to the judgment result.
