具体地，在刚开始进行烹饪时，可以给灶具20预先设置一个防干烧温度阈值，本申请实施方式的第三防干烧温度值可以理解为灶具20预先设置的防干烧温度阈值，这样在灶具20开启时，当检测到锅具30的温度大于第三防干烧温度值时可以及时控制灶具20关闭。例如，在刚开始烹饪时，用户可能由于失误放置在一个空的锅具30在灶具20上长时间干烧，此时，通过检测锅具30的温度可及时控制灶具20关闭。
请参阅图2及图4，在某些实施方式中，控制方法包括：
S110，判断锅具30的温度是否大于或者等于预设温度值，预设温度值小于第三防干烧温度值；
若锅具30的温度大于或等于预设温度值，进入步骤S20，判断采集到锅具30的温度的数量是否大于预设数量的步骤；
若锅具30的温度小于预设温度值，进入步骤S10，继续采集锅具30的温度。
本实施方式的控制方法可以由本申请实施方式的防干烧系统100实现，其中，本申请实施方式的防干烧的控制方法的步骤S50可以由控制装置50实现。也就是说，判断模块220用于若锅具30的温度小于第三防干烧温度值，判断锅具30的温度是否大于或者等于预设温度值，预设温度值小于第三防干烧温度值；若锅具30的温度大于或等于预设温度值，进入判断采集到锅具30的温度的数量是否大于预设数量的步骤；若锅具30的温度小于预设温度值，采集模块210用于继续采集锅具30的温度。
如此，通过在锅具30的温度大于或者等于预设温度值时才开始判断采集到所述锅具30的温度的数量是否大于预设数量，这样可以减少控制装置50的运算时间，提高控制装置50的工作效率。
具体地，由于刚开始进行正常的烹饪时，锅具30的温度还比较低，此时通过设置预设温度值，并且在检测到锅具30的温度大于预设温度值时才开始根据锅具30的温度判断锅具30的烹饪状态，这样可以提高控制装置50的运算的效率，并且可以更加准确地获取锅具30的烹饪状态。
进一步地，当烹饪持续下去时，当采集到锅具30的温度的数量是否大于预设数量时，可通过锅具30的温度和温度区间获取灶具20所处于的烹饪状态，并且在灶具20处于有水烹饪状态时获取与有水烹饪状态对应的第一防干烧温度值作为灶具20的防干烧温度阈值；当灶具20处于无水烹饪状态时，由于进行无水烹饪时锅具30的温度较高，因此本实施方式获取与无水烹饪状态对应的大于第一防干烧温度值的第二防干烧温度值作为灶具20的防干烧温度阈值，从而可以避免灶具20由于误判而提前断火或者防止干烧时间过长。
请参阅图2，锅具30的温度可由温度传感器40测量。在一个实施例中，温度传感器40可设置在灶具20上，例如温度传感器40为灶具20的防干烧温度探头。防干烧温度探头可设置在灶具20的燃烧器中。所采集到的锅具30的温度可以理解为温度传感器40(如防干烧温度探头)所输出的温度数据，与灶具20上是否放置有锅具30没有必然联系。当锅具30放置在灶具20上时，锅具30与防干烧温度 探头弹性抵接，以使防干烧温度探头获取到更准确的锅具30的温度。
在另外一个实施例中，锅具30的温度由设置在锅具30的温度传感器40来检测。温度传感器40可为无线无源温度传感器40。无线无源温度传感器40不需电源供电，并可以通过无线方式将采集到的温度数据发送出去。
在又一个实施方式中，温度传感器40可为其它温度传感器40，温度传感器40可设置在锅具30的锅体底部的夹层内，温度传感器40采集到的锅具30的温度可通过设置在锅具30把手的温度信号发射单元发送至控制装置50。
本申请实施方式中，控制灶具20关闭主要是指控制灶具20停止加热，例如，对于灶具20是电磁灶时，切断线圈的电流，对于灶具20是燃气灶时，控制装置50可以给电磁阀发送关闭指令，切断灶具20的供气。
在某些实施方式中，根据锅具30的温度确定温度区间，包括：计算预设时长内锅具30的温度平均值，并根据锅具30的温度平均值确定温度区间。在一个实施中，根据锅具30的温度平均值确定温度区间可以为：将锅具30的温度平均值加上第一预设值以得到上限值；将锅具30的温度平均值减去第一预设值以得到下限值，上限值和下限值限定出温度区间。具体的，当采集到的锅具30的温度T k的数量大于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，将平均值Tmean加上第一预设值m以得到上限值，及将平均值Tmean减去第二预设值n以得到下限值，也就是说，温度区间可以为[Tmean-n，Tmean+m]。需要说明的是，本实施方式的m值和n值可以根据实施情况预先进行标定，根据采集到的锅具30的数据的实际情况而进行不同的标定，例如，在一个例子中，m值可为1，n值可为2；而在另外一个例子中，m的值可为2，n的值可为2。m值和n值可根据实际情况进行选取，在此不作限定。
在某些实施方式中，根据锅具30的温度确定温度区间，包括：选择预设时长内的其中一个锅具30的温度，并根据所选择的锅具30的温度确定温度区间。在一个实施中，根据所选择的锅具30的温度确定温度区间可以为：将预设时长内的其中一个锅具30的温度加上第一预设值以得到上限值；将预设时长内的其中一个锅具30的温度减去第一预设值以得到下限值，上限值和下限值限定出温度区间。具体地，当采集到的锅具30的温度T k的数量大于预设定值N时(即k＞N)，将T k-N至T k的区间内N+1个锅具30的温度中的任一个锅具30的温度T k加上第一预设值m以得到温度区间上限值，及将锅具30的温度T k减去第二预设值n以得到下限值，也就是说，温度区间可以为[T k-n，T k+m]。需要说明的是，本实施方式的m值和n值可以根据实施情况预先进行标定，根据采集到的锅具30的数据的实际情况而进行不同的标定，例如，在一个例子中，m值可为1，n值可为2；而在另外一个例子中，m的值可为2，n的值可为2。m值和n值可根据实际情况进行选取，在此不作限定。
需要说明的是，预设时长可设置为不同值，相应地可以根据实际情况，预设值的大小也可对应调整为与预设时长的时间长度所对应的预设值，在此不作限制。在一个例子中，预设时长可为2分钟，每隔两秒采集一个锅具30的温度数据，N的值可为60，若k为80，则T k-N至T k的区间内N+1个锅具30的温度的数据可以理解为：在2分钟内，T20至T80一共61个锅具30的温度数据。可以理解，这些具体数值及以下实施方式所举的具体数值只是作为例子来说明本申请的实施，而不应理解为对本申请的限制。由于锅具30的温度数据是每隔一个时长来获取的，因此，当获取到一定数量的锅具30的温度数据时，相应地会有一个获取到这些数量的锅具30的温度数据的时长。也就是说，预设时长的具体数值可与所需要的锅具30的温度数量相关联。
请参阅图2及图5，在某些实施方式中，步骤S30包括步骤：
S32，根据锅具30的温度和温度区间判断是否存在锅具30的沸腾段；
若是，S34，确定灶具20处于有水烹饪状态；
若否，S36，确定灶具20处于无水烹饪状态。
本申请实施方式的防干烧的控制方法可以由本申请实施方式的防干烧系统100实现。其中，本申请实施方式的防干烧的控制方法的步骤S32、S34及S36可以由控制装置50实现。也就是说，判断模块220用于根据锅具30的温度和温度区间判断是否存在锅具30的沸腾段；若是，确定灶具20处于有水烹饪状态；若否，处理模块230用于确定灶具20处于无水烹饪状态。
如此，通过判断是否存在锅具30的沸腾段来确定灶具20的烹饪状态，准确性高，简单易得。
具体地，锅具30的沸腾段可理解为锅具30处于有水烹饪状态的沸腾阶段时锅具30所达到的温度段。需要说明的是，当锅具30内的水沸腾时锅具30内水的温度会维持在一个稳定的温度段，此时，热量传输至锅具30的外表面是锅具30的外表面的温度也会维持在一个稳定的温度段。锅具30外表面的温度的波动范围在预定范围内时也可以理解处于沸腾段。
通常地，有水烹饪可为炖、煮、煲、蒸等温度变化率变化较小的有水烹饪方式。无水烹饪包括煎、炒、炸等温度变化率变化较大的无水烹饪方式。当灶具20处于有水烹饪状态时，请结合图6，经申请人研究发现，锅具30的温度时间曲线1和2具有典型的三段分布特点，温度时间曲线1和温度时间曲线2分别为锅具30的温度与时间的温度曲线：第一段：灶具20在开始加热时，锅具30的温度逐渐上 升；第二段：当锅具30内水分沸腾时，锅具30的温度处于恒定或近似恒定的状态，也就是说此时锅具30存在沸腾段；第三段：当锅具30内水分烧干时，锅具30的温度再次上升。其中，对于导热性好的锅具30，如金属锅具30，锅内水沸腾时锅底外表面温度较低，例如110℃-130℃，如温度时间曲线1所示；对于导热性差的锅具30，如砂锅，锅内水沸腾时锅底外表面温度较高。例如140℃-180℃，如温度时间曲线2所示。当灶具20处于无水烹饪状态时，温度时间曲线3为锅具30的温度与时间的温度曲线如图7所示，其锅具30的温度与时间的温度曲线3波动较大，无明显规律，也就是说在无水烹饪状态下，锅具30一般来说不存在沸腾段。
需要说明的是，有水烹饪状态对应的防干烧温度阈值及无水烹饪状态对应的防干烧温度阈值均可为预先设置。灶具20处于有水烹饪状态时达到防干烧时的温度比较低，而灶具20处于无水烹饪状态时达到防干烧时的温度比较高，因此，有水烹饪状态对应的防干烧温度阈值低于无水烹饪状态对应的防干烧温度阈值。也就是说，第二防干烧温度值大于第一防干烧温度值。
在本申请实施方式中，控制装置50可根据锅具30的温度和温度区间确定出灶具20的烹饪状态后，可根据不同的烹饪状态获取不同的防干烧温度阈值。
控制装置50的部分功能或全部功能可由灶具20本身的控制器或处理器、或控制板，或电脑板来实现，或控制装置50制作成单独的包括控制器、处理器、控制板或电脑板的控制盒或控制终端，安装在灶具20上，或灶具20外的其它位置。也就是说，防干烧系统100可由具有控制装置50的灶具20来实现。因此，本申请的防干烧系统100的保护范围也包括具有控制装置50功能的灶具20。可以理解，控制装置50还包括存储器，其用于存储控制装置50以实施上述的防干烧的控制方法的指令或程序。

上述实施方式的控制方法通过计算预设时长内锅具30的温度的平均值，并根据用于判断预设时长内所有锅具30的温度是否均处于温度区间来确定锅具30是否存在沸腾段，如此，可以准确并快速地确定灶具20的烹饪状态和获得锅具沸腾温度。
需要说明的是，本实施方式判断预设时长内所有锅具30的温度是否均处于温度区间，在一个实施例中，可以先计算预设时长内的锅具30的温度平均值，再判断用于计算平均值的所有锅具30的温度是否均处于温度区间。当然，在另外一个实施例中，也可以直接判断预设时长内所有锅具30的温度是否均处于温度区间。
请参阅图2及图10，步骤S32包括步骤：
S722，判断预设时长内所有锅具30的温度中的最大值及最小值是否均处于温度区间，若是，S724，确定锅具30存在沸腾段并根据锅具30的温度确定锅具沸腾温度；若否，S726，确定锅具30不存在沸腾段。
本申请实施方式的防干烧的控制方法可以由本申请实施方式的防干烧系统100实现。其中，本申请实施方式的防干烧的控制方法的步骤S722、S724及S726可以由控制装置50实现。也就是说，判断模块220用于判断预设时长内所有锅具30的温度中的最大值及最小值是否均处于温度区间，若是，处理模块230用于确定锅具30存在沸腾段并根据锅具30的温度确定锅具沸腾温度；若否，处理模块230用于确定锅具30不存在沸腾段。
上述实施方式的控制方法通过计算预设时长内锅具30的温度的平均值，并根据用于判断预设时长内所有锅具30的温度中的最大值及最小值是否均处于温度区间来确定锅具30是否存在沸腾段，如此，可以准确并快速地确定灶具20的烹饪状态和获得锅具沸腾温度。
需要说明的是，本实施方式判断预设时长内所有锅具30的温度中的最大值及最小值是否均处于温度区间，在一个实施例中，可以先计算预设时长内的锅具30的温度平均值，再判断用于计算平均值的所有锅具30的温度中的最大值及最小值是否均处于温度区间。当然，在另外一个实施例中，也可以直接判断预设时长内所有锅具30的温度中的最大值及最小值是否均处于温度区间。
需要说明的是，根据锅具30的温度确定锅具沸腾温度可以由以下任一实施方式来获取。
在某些实施方式中，根据锅具30的温度确定锅具沸腾温度，包括：
将平均值作为锅具沸腾温度；或
将预设时长内的其中一个锅具30的温度作为锅具沸腾温度；或
将预设时长内的所有或部分锅具30的温度加权平均后的温度作为锅具沸腾温度；或
将温度区间的上限或下限或温度区间内其中一个值作为锅具沸腾温度。
具体地，根据锅具30的温度确定锅具沸腾温度包括将平均值作为锅具沸腾温度。在一个实施例中，当采集到的锅具30的温度T k的数量大于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，根据锅具30的温度确定温度区间，计算T k-N至T k的区间内N+1个锅具30的温度是否都在该温度区间，若T k-N至T k的区间内N+1个锅具30的温度都在该温度区间，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态，且将此时的锅具30的温度的平均值Tmean作为锅具沸腾温度Tb，若T k-N至T k的区间内N+1个锅具30的温度中有其中一个锅具30的温度不在该温度区间，则判定锅具30处于煎、炒、炸等无水烹饪状态，也就是说锅具30不存在沸腾段。
具体地，根据锅具30的温度确定锅具沸腾温度将预设时长内的其中一个锅具30的温度作为锅具沸腾温度，在一个实施例中，当采集到的锅具30的温度T k的数量大于或者等于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，根据锅具30的温度确定温度区间，计算T k-N至T k的区间内N+1个锅具30的温度是否都在该温度区间，若T k-N至T k的区间内N+1个锅具30的温度都在该温度区间，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态，且将T k-N至T k的区间内N+1个锅具30的温度中的其中一个锅具30的温度数据作为锅具沸腾温度Tb，若T k-N至T k的区间内N+1个锅具30的温度中有其中一个锅具30的温度不在该温度区间，则判定锅具30处于煎、炒、炸等无水烹饪状态，也就是说锅具30不存在沸腾段。
具体地，根据锅具30的温度确定锅具沸腾温度包括将预设时长内的所有或部分锅具30的温度加权平均后的温度作为锅具沸腾温度，在一个实施例中，当采集到的锅具30的温度Tk数量大于或者等于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，根据锅具30的温度确定温度区间，计算T k-N至T k的区间内N+1个锅具30的温度是否都在该温度区间，若T k-N至T k的区间内N+1个锅具30的温度都在该温度区间，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态，且将T k-N至T k的区间内所有或部分的N+1个锅具30的温度加权平均后的温度作为锅具沸腾温度Tb，若T k-N至T k的区间内N+1个锅具30的温度中有其中一个锅具30的温度不在该温度区间，则判定锅具30处于煎、炒、炸等无水烹饪状态，也就是说锅具30不存在沸腾段。
需要说明的是，将T k-N至T k的区间内所有或部分的N+1个锅具30的温度加权平均后的温度作为锅具沸腾温度Tb，可以理解为，在一个实施方式中，将T k-N至T k的区间内的N+1个锅具30的温度中的每一个锅具30的温度或者部分的锅具30的温度根据实际情况乘以不同的权值后取平均值，再将加权平均后所获得的温度作为锅具沸腾温度，需要指出的是，后采集的锅具30的温度所乘以的权值可以大于先采集的锅具30的温度所乘以的权值。
具体地，根据锅具30的温度确定锅具沸腾温度包括将温度区间的上限或下限或温度区间内其中一个值作为锅具沸腾温度。在一个实施例中，当采集到的锅具30的温度T k的数量大于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，根据锅具30的温度确定温度区间，计算T k-N至T k的区间内N+1个锅具30的温度是否都在该温度区间，若T k-N至T k的区间内N+1个锅具30的温度都在该温度区间，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态，且将温度区间的上限或下限或温度区间内其中一个值作为锅具沸腾温度Tb，若T k-N至T k的区间内N+1个锅具30的温度中有其中一个锅具30的温度不在该温度区间，则判定锅具30处于煎、炒、炸等无水烹饪状态，也就是说锅具30不存在沸腾段。
需要说明的是，将温度区间的上限或下限或温度区间内其中一个值作为锅具沸腾温度Tb，可以理解为，在TT k-N至T k的区间内N+1个锅具30的温度均在温度区间内，此时可以将温度区间的上限或温度区间的下限或T k-N至T k的区间内N+1个锅具30的温度的任一个温度数据作为锅具沸腾温度Tb。
在某些实施方式，上述实施方式的锅具30的温度的平均值Tmean的数量是多个，根据所述锅具30的温度确定锅具沸腾温度，控制方法还包括：将多个平均值加权后的加权平均值作为锅具沸腾温度。需要指出的是，在一个实施方式中，后获取的锅具30的温度的平均值的权重可大于先获取的锅具30 的温度的平均值的权重。
具体地，由于当锅具30处于沸腾段时，锅具30的温度会存在着比较小的波动，也就是说，沸腾温度也会存在波动，为了获得更加准确的锅具沸腾温度，本实施方式在当采集到的锅具30的温度T k的数量大于预设定值N后，每采集一个数据后都会将前面预设时长内所采集到的数据进行平均值的计算，这样可以得到多个平均值，进而在将多个平均值进行加权平均后所得到的温度数据作为锅具沸腾温度。在一个实施例中，当采集到的锅具30的温度T k的数量大于预设定值N时(即k＞N)，计算T k-N至T k的区间内N+1个锅具30的温度的数据的平均值Tmean，根据锅具30的温度确定温度区间，计算T k-N至T k的区间内N+1个锅具30的温度是否都在该温度区间，若T k-N至T k的区间内N+1个锅具30的温度都在该温度区间，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态，同时，可以在T k-N至T k的区间内计算多个锅具30的温度的平均值Tmean，将多个平均值加权后的加权平均值作为锅具沸腾温度，这样锅具沸腾温度Tb可以实时更新，精确度高。
另外，若T k-N至T k的区间内N+1个锅具30的温度中有其中一个锅具30的温度不在该温度区间，则判定灶具20处于煎、炒、炸等无水烹饪状态，也就是说锅具30不存在沸腾段。
请参阅图2及图11，在某些实施方式中，在某些实施方式中，控制方法包括步骤：
S822，判断锅具沸腾温度是否小于预设导热温度；
若是，S824，根据锅具沸腾温度获取对应的第四防干烧温度值并将第四防干烧温度值作为灶具20的防干烧温度阈值；若否，S826，根据锅具沸腾温度获取对应的第五防干烧温度值并将第五防干烧温度值作为灶具20的防干烧温度阈值，第四防干烧温度值小于第五防干烧温度值。
本申请实施方式的防干烧的控制方法可以由本申请实施方式的防干烧系统100实现。其中，本申请实施方式的防干烧的控制方法的步骤S822、S824及S826可以由控制装置50实现。也就是说，判断模块220用于判断锅具沸腾温度是否小于预设导热温度；若是，获取模块240用于根据锅具沸腾温度获取对应的第四防干烧温度值并将第四防干烧温度值作为灶具20的防干烧温度阈值；若否，获取模块240用于根据锅具沸腾温度获取对应的第五防干烧温度值并将第五防干烧温度值作为灶具20的防干烧温度阈值，第四防干烧温度值小于第五防干烧温度值。
如此，在灶具20处于有水烹饪状态时根据锅具30的导热性获取对应的防干烧温度阈值，这样可获取更加合适的防干烧温度阈值，以使灶具20可以准确地启动防干烧功能，避免发生误判。
需要说明的是，请参阅图6，对于导热性好的锅具30，如金属锅具30，锅内水沸腾时锅底外表面温度较低，例如110℃-130℃，如温度时间曲线1所示；对于导热性差的锅具30，如砂锅，锅内水沸腾时锅底外表面温度较高。例如140℃-180℃，如温度时间曲线2所示。因此可以通过沸腾时的锅具沸腾温度与预设导热温度的比较判定锅具30的类型。预设导热温度可以根据锅具30的导热性进行标定。进一步地，可通过比较锅具沸腾温度与预设导热温度的大小来确定不同的防干烧温度阈值，从而使得灶具20可以准确地启动防干烧功能，避免发生误判。
以下具体地实施例一及实施例二是根据上述实施方式的控制方法的整体描述。需要说明的是，实施例一及实施例二只是本申请的控制方法的具体实施例，本申请实施方式控制方法可根据实际情况组设计为其他的实施方式，在此不作限制。
