However, if food of different weights is added, the traditional air fryer can only heat a certain amount of food, and cannot heat and mature the ingredients of different weights, and cannot provide users with a satisfactory cooking process. The relationship between the weight of the ingredients and the corresponding heating time can only be tried and explored based on experience, and finally find out the cooking time to cook the food to the best taste. With the progress of society, people have higher and higher requirements for the taste and cooking effect of food, so an intelligent control algorithm is needed, which does not need to set the time, and can save the user from exploring the heating process in the initial cooking process. Then applying this algorithm to kitchen appliances can cater to the needs of consumers very well.

优选的，将每种食材按照重量不同分成不同的重量区间，将重量区间的极大值对应的最大水分浓度和极小值重量对应的最大水分浓度相减并取绝对值，重量区间极大值重量出现最大水分浓度时的对应时间减去重量区间极小值重量出现最大水分浓度时的对应时间后取绝对值。Preferably, each food material is divided into different weight intervals according to different weights, and the maximum moisture concentration corresponding to the maximum value of the weight interval is subtracted from the maximum moisture concentration corresponding to the minimum weight, and the absolute value is taken, and the maximum value of the weight interval is The absolute value is taken after subtracting the corresponding time when the weight has the maximum moisture concentration from the minimum value of the weight interval and the corresponding time when the weight has the maximum moisture concentration.

具体实施方式Detailed ways
以下结合附图和具体实施例对本发明作进一步详细说明。根据下面说明和权利要求书，本发明的优点和特征将更清楚。需说明的是，附图均采用非常简化的形式且均使用非精准的比例，仅用以方便、明晰地辅助说明本发明实施例的目的。The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in very simplified form and use inaccurate scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
本方案原理：本发明基于加热设备的恒定功率和烹饪室的空气中水份的浓度来确定所需烹饪时间。The principle of this scheme: the present invention determines the required cooking time based on the constant power of the heating equipment and the concentration of moisture in the air of the cooking chamber.
为了准确控制烹饪过程，有必要了解烹饪过程中食物的关键性质。特别是，这些关键性质可以在烹饪过程中测量或者预测食物的成熟度。空气炸锅加热过的食物都会丧失水分，空气流动速度越大，加热速度越快，经过空炸锅加热过的食物水分散失多，表面干脆感强。炉腔内空气中的水分子浓度可以作为判断食物成熟度的一个特性，在加热设备开启后的初始时间段内加热管以恒定功率加热，随着加热时间的增加，食材中的水分大量蒸出，加热室内的水蒸气的含量大幅度上升。根据加热室内水汽的浓度能准确的估计出剩余烹饪过程所需的时间。In order to accurately control the cooking process, it is necessary to understand the key properties of the food during cooking. In particular, these key properties can be used to measure or predict the ripeness of food during cooking. The food heated by the air fryer will lose moisture. The greater the air flow rate, the faster the heating speed. The food heated by the air fryer will lose more water and the surface will be crisper. The concentration of water molecules in the air in the oven cavity can be used as a characteristic to judge the maturity of food. During the initial period after the heating equipment is turned on, the heating tube is heated at a constant power. As the heating time increases, a large amount of water in the food will evaporate. , the content of water vapor in the heating chamber increases significantly. The time required for the remaining cooking process can be accurately estimated according to the concentration of water vapor in the heating chamber.
本发明能够对食物进行成熟度的估计，并且能够在烹饪阶段的中期向用户提供剩余的烹饪时间，如图1，本发明提供了一种使用湿度传感器通过选定食物进行智能烹饪的方法，包括：湿度传感器，使其能够在高温高湿的工作环境下准确辨别该环境下的空气中水分的浓度，将采集到的湿度信息传输至主控系统。经过大量测试数据训练出的自动烹饪算法模型，可操控的恒功率加热系统，能够自动监测烤制过程，在加热过程中计算剩余烹饪时间，最终能够实现多种食材的自动烹饪。The present invention can estimate the maturity of the food, and can provide the user with the remaining cooking time in the middle of the cooking stage, as shown in Figure 1, the present invention provides a method for intelligent cooking by selecting food using a humidity sensor, including : The humidity sensor enables it to accurately identify the concentration of moisture in the air in the high-temperature and high-humidity working environment, and transmit the collected humidity information to the main control system. The automatic cooking algorithm model trained by a large amount of test data, the controllable constant power heating system, can automatically monitor the baking process, calculate the remaining cooking time during the heating process, and finally realize the automatic cooking of various ingredients.
将每种食材按照重量不同分成不同的重量区间，将重量区间的极大值对应的最大水分浓度和极小值重量对应的最大水分浓度相减并取绝对值，重量区间极大值重量出现最大水分浓度时的对应时间减去重量区间极小值重量出现最大水分浓度时的对应时间后取绝对值，智能调控时间的算法借助于公式1-1：Divide each food material into different weight intervals according to their weight, subtract the maximum moisture concentration corresponding to the maximum value of the weight interval from the maximum moisture concentration corresponding to the minimum weight, and take the absolute value. The maximum weight of the weight interval appears the largest The absolute value is taken after subtracting the corresponding time when the moisture concentration is the minimum value in the weight interval and the corresponding time when the maximum moisture concentration occurs. The algorithm for intelligent time control is based on formula 1-1:
T＝T0+((Wx-W0)/|W1-W0|)*|T1-T0|(1-1)T＝T0 +((Wx-W0 )/|W1 -W0 |)*|T1 -T0 |(1-1)
T为实际的加热时间，T0为在食物加热过程中炉腔内出现最大水分浓度峰值的时间所对应的在重量区间的最小值的重量所对应的水分子浓度峰值所对的时间，T1为所对应的区间的最大值的重量所对应的水分子浓度峰值所对应的时间，W0为放入食物的重量所对应的重量区间的右端的水汽浓度数值，W1为放入食物的重量对应重量区间左端的水汽浓度数值，Wx为放进食物的实际重量所对应的最大水分浓度的数值，由传感器直接测量。T is the actual heating time, T0 is the time corresponding to the peak value of the water molecule concentration corresponding to the minimum weight in the weight interval corresponding to the time when the maximum moisture concentration peak appears in the oven cavity during the food heating process, T1 W0 is the water vapor concentration value at the right end of the weight interval corresponding to the weight of the food put in, and W1 is the weight of the food put in Corresponding to the water vapor concentration value at the left end of the weight range, Wx is the maximum water concentration value corresponding to the actual weight of the food put in, which is directly measured by the sensor.
将算法用程序写好之后，对空气炸锅的实际效果进行验证，将准备好的食物放进空气炸锅内，烹饪过后观察食物是否达到要求，如果没有，再适当延长或者缩短该重量的食物最大水气浓度对应的时间。依旧代入公式，直至食物达到满意的成熟度为止。After the algorithm is written in the program, verify the actual effect of the air fryer, put the prepared food into the air fryer, and observe whether the food meets the requirements after cooking. If not, then appropriately extend or shorten the weight of the food The time corresponding to the maximum water vapor concentration. Still substitute into the formula until the food reaches a satisfactory degree of maturity.
具体的实施时：分为测试阶段，验证阶段，调整阶段，以烹饪薯条为例。The specific implementation time: it is divided into testing phase, verification phase, and adjustment phase, taking cooking French fries as an example.
测试阶段：首先需要把需要放入微空烤箱的食材确定为薯条类在实验过程中，通过实验获得的数据和空气炸锅的炉腔大小和空气炸锅的结构也有关系，选择一款合适的空气炸锅，根据特定的空气炸锅类型进行试验，选择配套的烤架，烤盘。Testing stage: firstly, it is necessary to determine the ingredients that need to be put into the micro-air oven as French fries. During the experiment, the data obtained through the experiment is also related to the size of the cavity of the air fryer and the structure of the air fryer. Choose a suitable one. According to the specific type of air fryer, experiment, choose the matching grill, baking pan.
在测试食材的时候，要将食材细分为不同的重量，每种重量存在一定间隔，例如，薯条的最大烹饪重量为500克，将薯条分为0克，100克，200克，300克，400克，500克，在400F的恒定加热功率下，分别放入空炸锅内进行测试，记录不同重量的同种食材的加热时间，记录整个过程中炉腔内不断变化的湿度，反复做几次，求平均时间。When testing the ingredients, it is necessary to subdivide the ingredients into different weights, and there is a certain interval between each weight. For example, the maximum cooking weight of French fries is 500 grams, and the French fries are divided into 0 grams, 100 grams, 200 grams, and 300 grams. Grams, 400 grams, 500 grams, under the constant heating power of 400F, put them into the air fryer for testing, record the heating time of the same kind of ingredients with different weights, record the changing humidity in the oven cavity during the whole process, repeat Do this several times and find the average time.
验证阶段：将每种重量在烹饪过程中的最大湿度值和加热总时长都写进程序，分别加入不同重量的薯条，观察和记录判断出的重量以及最后的脱水率。Verification stage: Write the maximum humidity value and total heating time of each weight in the cooking process into the program, add French fries of different weights, observe and record the judged weight and the final dehydration rate.
调整阶段：根据误差，适当调整。即可烤出美味可口的薯条。Adjustment stage: adjust appropriately according to the error. Delicious French fries are ready to bake.
