在相关技术中，家用灶具中设置的防干烧功能可以在锅具的温度达到防干烧温度阈值时自动关闭灶具。但是，现有防干烧控制方法统一使用同一防干烧温度阈值，锅具的温度高于该防干烧温度阀值即判断干烧发生。同时，在灶具发生干烧之前或者刚开始干烧时不能及时通知用户关闭灶具，当锅具的温度达到防干烧温度阈值时，锅内已经发生干烧并持续一定时间，容易造成锅内食物碳化，锅具难以清洁等情况，用户体验性差。

请一并参阅图1至图3，本申请实施方式的防干烧的控制方法用于灶具20。在一个实施例中，防干烧的控制方法包括：
步骤S10，采集锅具30的温度；
步骤S20，判断锅具30的温度是否大于灶具20的防干烧温度阈值；
若锅具30的温度大于灶具20的防干烧温度阈值，步骤S30，控制灶具20关闭；
若锅具30的温度不大于灶具20的防干烧温度阈值；步骤S40，判断锅具30的温度是否大于报警温度阈值；若锅具30的温度大于报警温度阈值，步骤S50，控制灶具20发出报警信息；若锅具30的温度不大于报警温度阈值，继续进入步骤S10。
本申请实施方式的防干烧系统100包括灶具20和控制装置50，控制装置50连接灶具20。控制装置50包括采集模块210、判断模块220及处理模块230。作为例子，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，并应用于灶具20。
其中，本申请实施方式的防干烧的控制方法的步骤S10、步骤S20、步骤S30、步骤S40及步骤S50可以由控制装置50实现。也就是说，采集模块210用于采集锅具30的温度；判断模块220用于判断锅具30的温度是否大于灶具20的防干烧温度阈值；若锅具30的温度大于灶具20的防干烧温度阈值，处理模块230用于控制灶具20关闭；若锅具30的温度不大于灶具20的防干烧温度阈值；判断模块220用于判断锅具30的温度是否大于报警温度阈值；若锅具30的温度大于报警温度阈值，处理模块230用于控制灶具20发出报警信息；若锅具30的温度不大于报警温度阈值，采集模块210继续采集锅具30的温度。其中，防干烧温度阈值大于报警温度阈值。
本申请实施方式的防干烧的控制方法及防干烧系统100中，在锅具30的温度大于防干烧温度阈值时控制灶具20关闭，并在锅具30的温度大于报警温度阈值时控制灶具20发出报警信息，如此，这样使得灶具20在发生干烧之前或者刚开始发生干烧时可以及时通知用户注意灶具的烹饪情况，用户体验性好。
在图1的示例中，先判断锅具30的温度是否大于防干烧温度阈值，在锅具30的温度大于防干烧温度阈值时直接控制灶具20关闭而不会再去执行判断锅具30的温度是否大于报警温度阈值的步骤，这样可以减少控制装置50的算法运算，提高执行效率。而在锅具30的温度不大于防干烧温度阈值才会执行判断锅具30的温度是否大于报警温度阈值的步骤，并且在锅具30的温度大于报警温度阈值发出报警信息，而在锅具30的温度不大于报警温度阈值，则继续采集锅具30的温度，并重新判断锅具30的温度是否大于防干烧温度阈值，以此循环，随着锅具30的温度的逐渐升高，直到锅具30的温度大于防干烧温度阈值时控制灶具20关闭。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可以给比例阀发送关闭指令，切断灶具20的供气，以使灶具20的燃烧器熄火。
需要指出的是，在控制灶具20关闭的同时，在一个实施例中，控制灶具20停止发出报警信息。在另一个实施例中，控制灶具20继续发出报警信息，而报警信息可以为提示灶具已关闭的语音，或者其他的提示方式提示灶具已关闭，在此不作限制。
需要说明的是，在另一个实施例中，可以先执行判断锅具30的温度是否大于报警温度阈值的步骤，在锅具30的温度大于报警温度阈值时控制灶具20发出报警信息，再去执行判断锅具30的温度是否大于灶具20的防干烧温度阈值，随着温度的逐渐升高，在锅具30的温度大于灶具20的防干烧温度阈值控制灶具20关闭。在控制灶具20关闭的同时，在一个实施例中，控制灶具20停止发出报警信息。在另一个实施例中，控制灶具20继续发出报警信息，而报警信息可以为提示灶具20已关闭的语音，或者其他的提示方式提示灶具20已关闭，在此不作限制。
在又一个实施例中，判断锅具30的温度是否大于报警温度阈值的步骤和判断锅具30的温度是否大于灶具20的防干烧温度阈值的步骤可以由控制装置50同时执行，这样可以快速根据锅具30的温度控制灶具20的状态。
具体的，本申请实施方式中报警温度阈值和防干烧温度阈值可根据实际情况预先设置，当锅具30的温度大于报警温度阈值时可以及时通知用户注意灶具20的烹饪情况，以使得用户可以及时对灶具20做出操作，防止灶具20发生干烧。需要指出的是，本实施方式报警温度阈值的数值可以设置为接近防干烧温度阈值的数值，也就说是，在锅具30的温度达到报警温度阈值时，灶具20已经处于接近干烧状态或者处于刚开始干烧的状态。
需要说明的是，本申请实施方式的控制装置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还可包括存储器，其用于存储控制装置实施上述防干烧的控制方法的指令或程序。
请参阅图3，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。无线无源温度传感器不需电源供电，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，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。
在某些实施方式中，步骤S30包括：控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。
上述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。上述控制方法可以由控制装置50实现。也就是说，控制装置50用于控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。如此，这样可以快速并有效率地通知用户注意灶具20的烹饪情况。
具体地，在一个实施例中，报警信息可为灶具20的蜂鸣器发出的报警声音，报警声音可以每隔60秒报警一次，每次持续3秒。
在某些实施方式中，报警温度阈值包括不同的多个报警温度阈值，多个报警温度阈值与防干烧温度阈值限定出多个报警范围，报警信息包括多个报警信息，每个报警范围对应一个报警信息；控制灶具20发出报警信息，包括：根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
上述控制方法可以由控制装置50实现。也就是说，控制装置50用于根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
如此，根据锅具30的温度所处的报警范围以控制灶具20发出与报警范围对应的报警信息，这样可以让用户通过对应的报警信息获知灶具20的干烧状态，以便于可以及时做出处理，用户体验性好。
具体的，在一个实施例中，报警温度阈值分别包括第一报警温度阈值A和第二报警温度阈值B，其中，第一报警温度阈值A小于第二报警温度阈值B。第一报警温度阈值A、第二报警温度阈值B及防干烧温度阈值C共同限定出两个报警范围[A，B)和[B，C]。当锅具30的温度处于报警范围[A，B)时，控制灶具20发出第一报警信息，例如，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度处于报警范围[B，C]，控制灶具20发出第二报警信息，例如，报警声音每隔30秒报警一次，每次持续3秒，随着锅具30的温度的持续升高，当锅具30的温度大于防干烧温度阈值时，可以控制灶具20关闭并停止发出报警信息。
在某些实施方式中，灶具20发出报警信息的频率与报警范围的温度正相关。具体地，报警范围的温度越高，灶具20发出报警信息的频率就频繁。在一个实施例中，当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度落在[220，230)的报警范围内时，报警声音每隔30秒报警一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒。
在某些实施方式中，报警信息包括声音，声音的频率与报警范围的温度正相关。具体地，报警范围的温度越高，声音的频率就越高。在一个实施例中，报警信息为报警声音。当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒，报警声音为低频声音。当锅具30的温度落在[220，230)的报警范围内时，报警声音每隔30秒报警一次，每次持续3秒，报警声音为中频声音。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒，报警声音为高频声音。
在某些实施方式中，报警信息包括光，光的闪烁频率与报警范围的温度正相关。具体地，报警范围的温度越高，光的闪烁频率就越高。在一个实施例中，报警信息为报警显示灯发出的光。当锅具30的温度落在[210，220)的报警范围内时，报警显示灯每隔60秒闪烁一次，每次持续3秒。当锅具30的温度落在[220，230)的报警范围内时，报警显示灯每隔30秒闪烁一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警显示灯每隔15秒闪烁一次，每次持续3秒。
需要说明的是，在锅具30的温度大于报警温度阈值时，在一个实施方式中，可以控制灶具20同时发出报警声音和闪烁报警显示灯。在另一实施方式中，只控制灶具20同时发出报警声音，例如发出预设的语音“请注意锅温，防止干烧”。在又一个实施方式中，只控制灶具20闪烁报警显示灯，例如，报警显示灯报警闪烁红光。报警的信息可根据用户的实际需求进行设置，在此不作限定。
请参阅图3及图4，在某些实施方式中，控制方法包括：
步骤S110，接收报警终止指令；
步骤S120，根据报警终止指令，控制灶具20停止发出报警信息。
上述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S110及步骤S120可以由控制装置50实现。也就是说，处理模块230用于接收报警终止指令；及处理模块230用于根据报警终止指令，控制灶具20停止发出报警信息。
如此，可以根据用户需求灵活的控制灶具20的报警，用户体验性好。
具体地，可在灶具20上可设置一个按键或旋钮，用户按动按键或转动旋钮后，灶具20的报警可在预设时间内(例如2秒)解除，然后自动恢复至待报警状态。在一个实施方式中，灶具20的报警旋钮可与点火旋钮共用。
请参阅图5，在某些实施方式中，控制方法还包括：步骤S130，接收报警功能开启指令，进入步 骤S10。
上述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S130可以由控制装置50实现。也就是说，控制装置50用于接收报警功能开启指令；根据报警功能开启指令，进入步骤S10，采集锅具30的温度。如此，可以根据报警功能开启指令控制灶具20发报警信息，这样容易满足用户的需求，用户体验性好。
需要说明的是，本申请实施方式中，可在灶具20上设置一个报警功能按键，灶具出厂时，默认是关闭报警功能。在报警功能关闭的情况下，当报警功能按键被操作时，灶具产生报警功能开启指令，控制装置50可接收报警功能开启指令，判断锅具30的温度是否大于报警温度阈值，在锅具30的温度大于报警温度阈值时，控制灶具20发出报警信息。在报警功能开启的情况下，当报警功能按键被操作时，灶具产生报警功能关闭指令，控制装置50可接收到报警功能关闭指令，不判断锅具30的温度是否大于报警温度阈值，或在锅具30的温度大于报警温度阈值时，控制灶具20不发出报警信息。可以理解，在其它实施方式中，灶具20出厂时，可以默认是开启报警功能。在其它实施方式中，可在灶具20上设置一个报警功能开启按键和报警功能关闭按键。
进一步地，可在灶具20上设置一个报警音量按键，用户可通过调节报警音量按键以调节报警时发出的声音的音量大小。
具体的，在具体的实际应用场景中，防干烧温度阈值可预先设置为T1＝290℃。当报警温度阈值为一个时，报警温度阈值可设置为T2＝240℃。当锅具30的温度大于报警温度阈值T2时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T2＝240℃及T3＝260℃。当锅具30的温度大于报警温度阈值T2且小于或者等于T3时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T3且小于或者等于T1时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T1时，控制装置50控制灶具20关闭时停止发出报警声音。
以下具体地实施例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合或者设计为其他的实施方式，在此不作限制。

请参阅图3及图7，控制方法包括：
步骤S210，采集锅具30的温度和灶具20的当前火力；
步骤S220，根据灶具20的当前火力获取与当前火力对应的防干烧温度阈值，防干烧温度阈值与灶具20的火力正相关；
步骤S230，判断锅具30的温度是否大于灶具20的防干烧温度阈值；
若锅具30的温度大于灶具20的防干烧温度阈值，步骤S240，控制灶具20关闭；
若锅具30的温度不大于灶具20的防干烧温度阈值，步骤S250，根据灶具20的当前火力获取与当前火力对应的报警温度阈值，报警温度阈值与灶具20的火力正相关；
步骤S260，判断锅具30的温度是否大于报警温度阈值；
若锅具30的温度大于报警温度阈值，步骤S270，控制灶具20发出与报警温度阈值对应的报警信息；
若锅具30的温度不大于报警温度阈值，继续进入步骤S210。本申请实施方式的防干烧系统100包括灶具20和控制装置50，控制装置50连接灶具20。作为例子，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，并应用于灶具20。
其中，本申请实施方式的防干烧的控制方法的步骤S210、步骤S220、步骤S230、步骤S240、步骤S250、步骤S260及步骤S270可以由控制装置50实现。也就是说，采集模块210用于采集锅具30的温度和灶具20的当前火力；处理模块230用于根据灶具20的当前火力获取与当前火力对应的防干烧温度阈值，防干烧温度阈值与灶具20的火力正相关；判断模块220用于判断锅具30的温度是否大于灶具20的防干烧温度阈值；若锅具30的温度大于灶具20的防干烧温度阈值，处理模块230用于控 制灶具20关闭；若锅具30的温度不大于灶具20的防干烧温度阈值，处理模块230用于根据灶具20的当前火力获取与当前火力对应的报警温度阈值，报警温度阈值与灶具20的火力正相关；判断模块220用于判断锅具30的温度是否大于报警温度阈值；若锅具30的温度大于报警温度阈值，处理模块230用于控制灶具20发出与报警温度阈值对应的报警信息；若锅具30的温度不大于报警温度阈值，继续进入采集锅具30的温度和灶具20的当前火力的步骤。其中，灶具20的防干烧温度阈值大于报警温度阈值。
本申请实施方式的防干烧的控制方法及防干烧系统100中，根据灶具20的火力获取对应的报警温度阈值和防干烧温度阈值，在锅具30的温度大于防干烧温度阈值时控制灶具20关闭，并在锅具30的温度大于报警温度阈值时控制灶具20发出报警信息，如此，这样可以根据不同的火力获取更加准确定的报警温度阈值和防干烧温度阈值以防止灶具20发生防干烧误判断，并且灶具20在发生干烧之前就可以及时通知用户，用户体验性好。
在图7的示例中，先判断锅具30的温度是否大于防干烧温度阈值，在锅具30的温度大于防干烧温度阈值时直接控制灶具20关闭而不会再去执行根据灶具20的当前火力获取与当前火力对应的防干烧温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，这样可以减少控制装置50的算法运算，提高执行效率。而在锅具30的温度不大于防干烧温度阈值才会执行根据灶具20的当前火力获取与当前火力对应的防干烧温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，并且在锅具30的温度大于报警温度阈值发出报警信息。而在锅具30的温度不大于报警温度阈值，则继续采集锅具30的温度和灶具20的当前火力，并重新根据灶具20的当前火力获取与当前火力对应的防干烧温度阈值及判断锅具30的温度是否大于防干烧温度阈值，以此循环，随着锅具30的温度的逐渐升高，直到锅具30的温度大于防干烧温度阈值时控制灶具20关闭。

若锅具30的温度大于报警温度阈值，步骤380，控制灶具20发出与报警温度阈值对应的报警信息。
本申请实施方式的防干烧系统100包括灶具20和控制装置50，控制装置50连接灶具20。作为例子，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，并应用于灶具20。
其中，本申请实施方式的防干烧的控制方法的步骤S310、步骤S320、步骤S330、步骤S340、步骤S342、步骤S350、步骤S360、步骤S370及步骤S380可以由控制装置50实现。也就是说，采集模块210用于采集锅具30的温度；处理模块230用于根据灶具20的烹饪状态获取对应的防干烧温度阈值；处理模块230用于根据锅具30的温度确定灶具20的烹饪状态；判断锅具30的温度是否大于灶具20的防干烧温度阈值；若锅具30的温度大于灶具20的防干烧温度阈值，控制灶具20关闭；根据灶具20的烹饪状态获取对应的报警温度阈值；判断模块220用于判断锅具30的温度是否大于报警温度阈值；若锅具30的温度大于报警温度阈值，处理模块230用于控制灶具20发出与报警温度阈值对应的报警信息。其中，灶具20的防干烧温度阈值大于报警温度阈值。
本申请实施方式的防干烧的控制方法及防干烧系统100中，根据所述灶具20的烹饪状态获取对应的报警温度阈值和防干烧温度阈值，并在锅具30的温度大于防干烧温度阈值时控制灶具20关闭，及在锅具30的温度大于报警温度阈值时控制灶具20发出报警信息，如此，可以准确地获取灶具20的报警温度阈值及防干烧温度阈值，防止发生防干烧误判，同时，使得灶具20在发生干烧之前或者刚开始发生干烧时可以及时通知用户，用户体验性好。
在图8的示例中，先判断锅具30的温度是否大于防干烧温度阈值，在锅具30的温度大于防干烧温度阈值时直接控制灶具20关闭而不会再去执行根据灶具20的烹饪状态获取对应的报警温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，这样可以减少控制装置50的算法运算，提高执行效率。而在锅具30的温度不大于防干烧温度阈值才会执行根据灶具20的烹饪状态获取对应的报警温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，并且在锅具30的温度大于报警温度阈值发出与报警温度阈值对应的报警信息，而在锅具30的温度不大于报警温度阈值，则继续采集锅具30的温度，并重新判断锅具30的温度是否大于防干烧温度阈值，以此循环，随着锅具30的温度的逐渐升高，直到锅具30的温度大于防干烧温度阈值时控制灶具20关闭。
请参阅图3及图9，在某些实施方式中，烹饪状态包括有水烹饪状态和无水烹饪状态，步骤S320包括：
步骤S322，根据锅具30的温度判断锅具30是否存在沸腾段；
若是，步骤S324，确定灶具20处于有水烹饪状态；
若否，步骤S326，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S322、步骤S324及步骤S326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的温度判断锅具30是否存在沸腾段，若是，处理模块230用于确定灶具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的外表面时锅具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10，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11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报警温度阈值及防干烧温度阈值可为预先设置。同时，无水烹饪状态对应的报警温度阈值及防干烧温度阈值也可为预先设置。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，同样的，有水烹饪状态对应的报警温度阈值低于无水烹饪状态对应的报警温度阈值。
请参阅图3及图12，步骤S22包括：
步骤S522，判断采集到的锅具30的温度数量是否大于预设数量；
若是，步骤S524，计算预设时长内锅具30的温度的变化率；
步骤S525，判断预设时长内锅具30的温度的变化率是否小于或等于预设值，若是，步骤S526，确定锅具30存在沸腾段并将锅具30的当前温度作为锅具30的锅具沸腾温度；若否，步骤S528，确定锅具30不存在沸腾段。
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S522、步骤S524、步骤S525、步骤S526及步骤S528可以由控制装置50实现。也就是说，判断模块220用于判断采集到的锅具30的温度数量是否大于预设数量；若是，处理模块230用于计算预设时长内锅具30的温度的变化率；判断模块220用于判断预设时长内锅具30的温度的变化率是否小于或等于预设值，若是，处理模块230用于确定锅具30存在沸腾段并将锅具30的当前温度作为锅具30的锅具沸腾温度；若否，处理模块230用于确定锅具30不存在锅具沸腾温度。
上述实施方式的控制方法通过计算预设时长内锅具30的温度的变化率来确定锅具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30的锅具沸腾温度。
需要说明的是，本实施方式中的预设时长内锅具30的温度的变化率可以由以下任一实施方式来获取。
预设时长内锅具30的温度与预设时长内锅具30的温度的平均值之差的绝对值之和；
预设时长内锅具30的温度对时间的斜率；
预设时长内锅具30的温度的方差；
预设时长内锅具30的温度的标准差。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度与预设时长内锅具30的温度的平均值之差的绝对值之和来获取。在一个实施例中，当采集到的锅具30的温度T k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，计算得到预设时长内锅具30的温度平均值与锅具30的单个温度Ti之差的绝对值之和可以表示为：SUB＝∑|Ti-Tmean|(i＝k-N至k)，SUB大则表示温度变化大。当SUB小于或者等于预设值时，则表示锅具30的温度变化小，可以认为锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，灶具20处于有水烹饪状态，将此时的锅具30的当前温度数据T k作为锅具沸腾温度T b。需要指出 的是，当将锅具的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现SUB大于预设值，也认为锅具30是处于有水烹饪状态。
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，预设值可为10，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。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度对时间的斜率来实现。在一个实施例中，当采集到的锅具30的温度T k数量大于预设定值N时(即k＞N)，在预设时长的T k-N至T k的区间内，获取线性拟合T k-N至T k随时间变化的锅具30的温度对时间的斜率，即拟合得到y＝ax+b，如果a小于或者等于预设斜率，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，灶具20处于有水烹饪状态，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现a大于预设斜率，也认为锅具30是处于有水烹饪状态。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度的方差来实现。在一个实施例中，当采集的温度数据T k数量大于预设定值N时(即k＞N)，计算在预设时长中，T k-N至T k的区间内N+1个温度数据方差(VA)，VA大则表示锅具30的温度变化大。当VA小于或者等于预设值时(锅具30的温度变化小)，即锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现VA大于预设值，也认为锅具30是处于有水烹饪状态。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度的标准差来实现。在一个实施例中，当采集的温度数据T k数量大于预设定值N时(即k＞N)，计算在预设时长中，T k-N至T k的区间内N+1个温度数据标准差(STD)，STD大则表示锅具30的温度变化大。当STD小于或者等于预设值时(锅具30的温度变化小)，即锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现STD大于预设值，也认为锅具30是处于有水烹饪状态。
请参阅图3及图13，在某些实施方式中，控制方法包括：
步骤S3110，当灶具20处于有水烹饪状态时，将第一报警温度值设置为灶具20的报警温度阈值，将第一防干烧温度值设置为灶具20的防干烧温度阈值；
步骤S3120，当灶具20处于无水烹饪状态时，将第二报警温度值设置为灶具20的报警温度阈值，将第二防干烧温度值设置为灶具20的防干烧温度阈值。
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S3110及步骤S3120可以由控制装置50实现。也就是说，处理模块230用于当灶具20处于有水烹饪状态时，将第一报警温度值设置为灶具20的报警温度阈值，将第一防干烧温度值设置为灶具20的防干烧温度阈值；当灶具20处于无水烹饪状态时，将第二报警温度值设置为灶具20的报警温度阈值，将第二防干烧温度值设置为灶具20的防干烧温度阈值。第一报警温度值小于第二报警温度值，第一防干烧温度值小于第二防干烧温度值。
具体地，当锅具30处于炖、煮、煲、蒸等有水烹饪状态时，锅具30达到干烧时锅具30的温度较低，因此在本实施方式中将第一报警温度值设置为报警温度阈值，将第一防干烧值设置为防干烧温度阈值。当锅具30处于煎、炒、炸等无水烹饪状态，锅具30达到干烧时锅具30的温度较高，因此在本实施方式中将大于第一报警温度值的第二报警温度值设置为报警温度阈值，将大于第一防干烧值的第二防干烧温度值设置为防干烧温度阈值。
需要说明的是，在采集到的锅具30的温度数量小于或者等于预设数量，此时，采集到的锅具30的温度数量不足以确定灶具20具体的烹饪状态，在这种情况下，进入步骤S510，将第二报警温度值设置为灶具20的报警温度阈值，将第二防干烧温度值设置为灶具20的防干烧温度阈值。也就是说，以无水烹饪状态的控制策略来获取灶具20的报警温度阈值和防干烧温度阈值。
请参阅图14，在某些实施方式中，控制方法包括：步骤S3130，当灶具20处于有水烹饪状态时，根据锅具30的温度获取锅具30的导热性，根据锅具30的导热性获取对应的报警温度阈值和防干烧温度阈值。
上述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S3130可以由控制装置50实现。也就是说，控制装置50用于当灶具20处于有水烹饪状态时，处理模块230用于根据锅具30的温度获取锅具30的导热性，根据锅具30的导热性获取对应的报警温度阈值和防干烧温度阈值。
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报警温度阈值和防干烧温度阈值，这样可获取更加合适的报警温度阈值和防干烧温度阈值，以使灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判。
请参阅图3及图15，在某些实施方式中，步骤S3130包括：
步骤S3132，判断锅具沸腾温度是否小于或者等于预设导热温度，若是，步骤S3134，将第三报警温度值设置为灶具20的报警温度阈值及将第三防干烧温度值设置为灶具20的防干烧温度阈值；若否，步骤S3136，将第四报警温度值设置为灶具20的报警温度阈值及将第四防干烧温度值设置为灶具20的防干烧温度阈值。
上述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S3132、S3134及S3136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或者等于预设导热温度，若是，将第三报警温度值设置为灶具20的报警温度阈值及将第三防干烧温度值设置为灶具20的防干烧温度阈值；若否，将第四报警温度值设置为灶具20的报警温度阈值及将第四防干烧温度值设置为灶具20的防干烧温度阈值。其中，第三报警温度阈值小于第四报警温度阈值，第三防干烧温度阈值小于第四防干烧温度阈值。
如此，灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判。
需要说明的是，在有水烹饪状态下，导热性越好的锅具30在烹饪时锅具沸腾温度Tb越小，因此锅具30的导热性越好，设置的防干烧温度阀值和报警温度阈值也就越低。
请参阅图10，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报警温度阈值和防干烧温度阈值，从而使得灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判，用户体验性好。
在某些实施方式中，步骤S342包括：控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。
上述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。上述控制方法可以由控制装置50实现。也就是说，控制装置50用于控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。如此，这样可以快速并有效率地通知用户注意灶具20的烹饪情况。
具体地，在一个实施例中，报警信息可为灶具20的蜂鸣器发出的报警声音，报警声音可以每隔60秒报警一次，每次持续3秒。
在某些实施方式中，报警温度阈值包括不同的多个报警温度阈值，多个报警温度值阈值与防干烧温度阈值限定出多个报警范围，报警信息包括多个报警信息，每个报警范围对应一个报警信息；控制灶具20发出报警信息，包括：根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
上述控制方法可以由控制装置50实现。也就是说，控制装置50用于根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
如此，根据锅具30的温度所处的报警范围以控制灶具20发出与报警范围对应的报警信息，这样可以让用户通过对应的报警信息获知灶具20的干烧状态，以便于可以及时做出处理，用户体验性好。
具体的，在一个实施例中，报警温度值阈值分别包括第一报警温度值阈值A和第二报警温度值阈值B，其中，第一报警温度值阈值A小于第二报警温度值阈值B。第一报警温度值阈值A、第二报警温度值阈值B及防干烧温度阈值C共同限定出两个报警范围[A，B)和[B，C]。当锅具30的温度处于报警范围[A，B)时，控制灶具20发出第一报警信息，例如，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度处于报警范围[B，C]，控制灶具20发出第二报警信息，例如，报警声音每隔30秒报警一次，每次持续3秒，随着锅具30的温度的持续升高，当锅具30的温度大于防干烧温度阈值时，可以控制灶具20关闭并停止发出报警信息。
在某些实施方式中，灶具20发出报警信息的频率与报警范围的温度正相关。具体地，报警范围的温度越高，灶具20发出报警信息的频率就频繁。在一个实施例中，当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度落在[220，230)的报警范围内时，报警声音每隔30秒报警一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒。
在某些实施方式中，报警信息包括声音，声音的频率与报警范围的温度正相关。具体地，报警范围的温度越高，声音的频率就越高。在一个实施例中，报警信息为报警声音。当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒，报警声音为低频声音。当锅具30的温度落在[220，230)的报警范围内时，报警声音每隔30秒报警一次，每次持续3秒，报警声音为中频声音。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒，报警声音为高频声音。
在某些实施方式中，报警信息包括光，光的闪烁频率与报警范围的温度正相关。具体地，报警范围的温度越高，光的闪烁频率就越高。在一个实施例中，报警信息为报警显示灯发出的光。当锅具30的温度落在[210，220)的报警范围内时，报警显示灯每隔60秒闪烁一次，每次持续3秒。当锅具30的温度落在[220，230)的报警范围内时，报警显示灯每隔30秒闪烁一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警显示灯每隔15秒闪烁一次，每次持续3秒。
需要说明的是，在锅具30的温度大于报警温度值阈值时，在一个实施方式中，可以控制灶具20同时发出报警声音和闪烁报警显示灯。在另一实施方式中，只控制灶具20同时发出报警声音，例如发出预设的语音“请注意锅温，防止干烧”。在又一个实施方式中，只控制灶具20闪烁报警显示灯，例如，报警显示灯报警闪烁红光。报警的信息可根据用户的实际需求进行设置，在此不作限定。
请参阅图3及图16，在某些实施方式中，控制方法包括：
步骤S3210，接收报警终止指令，进入步骤S310；
步骤S3220，根据报警终止指令，控制灶具20停止发出报警信息。
上述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S3210及步骤S3220可以由控制装置50实现。也就是说，处理模块230用于接收报警终止指令；及根据报警终止指令，处理模块230用于控制灶具20停止发出报警信息。
如此，可以根据用户需求灵活的控制灶具20的报警，用户体验性好。
具体地，可在灶具20上可设置一个按键或旋钮，用户按动按键或转动旋钮后，灶具20的报警可在预设时间内(例如2秒)解除，然后自动恢复至待报警状态。在一个实施方式中，灶具20的报警旋钮可与点火旋钮共用。
请参阅图17，在某些实施方式中，控制方法还包括：步骤S3230，接收报警功能开启指令，进入步骤S310；
上述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S3230可以由控制装置50实现。也就是说，控制装置50用于接收报警功能开启指令；进入步骤S310，采集锅具30的温度。如此，可以根据报警功能开启指令控制灶具20发报警信息，这样容易满足用户的需求，用户体验性好。
需要说明的是，本申请实施方式中，可在灶具20上设置一个报警功能按键，灶具20出厂时，默认是关闭报警功能。在报警功能关闭的情况下，当报警功能按键被操作时，灶具20产生报警功能开启指令，控制装置50可接收报警功能开启指令，判断锅具30的温度是否大于报警温度值阈值，在锅具30的温度大于报警温度值阈值时，控制灶具20发出报警信息。在报警功能开启的情况下，当报警功能按键被操作时，灶具20产生报警功能关闭指令，控制装置50可接收到报警功能关闭指令，不判断锅具30的温度是否大于报警温度值阈值，或在锅具30的温度大于报警温度值阈值时，控制灶具20不发出报警信息。可以理解，在其它实施方式中，灶具20出厂时，可以默认是开启报警功能。在其它实施方式中，可在灶具20上设置一个报警功能开启按键和报警功能关闭按键。
进一步地，可在灶具20上设置一个报警音量按键，用户可通过调节报警音量按键以调节报警时发出的声音的音量大小。
具体地，在具体的实际应用场景中，根据锅具30所处的烹饪状态及锅具30的导热性获取对应的报警温度阈值及防干烧温度阈值。在一个实施例中，锅具30处于有水烹饪状态，当锅具沸腾温度小于或者等于预设导热温度时，即表明锅具30的导热性较好，防干烧温度阈值可设置为T1＝210℃。当报警温度为一个时，报警温度阈值可设置为T2＝170℃。当锅具30的温度大于报警温度阈值T2时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T2＝170℃及T3＝190℃。当锅具30的温度大于报警温度阈值T2且小于或者等于T3时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T3且小于或者等于T1时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T1时，控制装置50控制灶具20关闭时停止发出报警声音。
在另一个实施方式中，锅具30处于有水烹饪状态，当锅具沸腾温度大于预设导热温度时，即表明锅具30的导热性较差，防干烧温度阈值可设置为T4＝250℃。当报警温度阈值为一个时，报警温度阈值可设置为T5＝220℃。当锅具30的温度大于报警温度阈值T2时，控制装置50可控制灶具20每隔60 秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T5＝220℃及T6＝235℃。当锅具30的温度大于报警温度阈值T5且小于或者等于T6时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T6且小于或者等于T4时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T4时，控制装置50控制灶具20关闭时停止发出报警声音。
在又一个实施例中，锅具30处于无水烹饪状态，防干烧温度阈值可设置为T7＝290℃。当报警温度阈值为一个时，报警温度阈值可设置为T8＝240℃。当锅具30的温度大于报警温度阈值T2时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T8＝240℃及T9＝260℃。当锅具30的温度大于报警温度阈值T8且小于或者等于T9时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T9且小于或者等于T7时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T7时，控制装置50控制灶具20关闭时停止发出报警声音。
具体地，在具体的实际应用场景中，只根据锅具30所处的烹饪状态获取对应的报警温度阈值及防干烧温度阈值。在一个实施例子中，锅具30的沸腾温度为Tb，锅具30处于有水烹饪状态时，防干烧温度阈值可设置为T10＝(Tb+80)℃。当报警温度阈值为一个时，报警温度阈值可设置为T11＝(Tb+50)℃。当锅具30的温度大于报警温度阈值T11时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T11＝(Tb+50)℃及T12＝(Tb+65)℃。当锅具30的温度大于报警温度阈值T11且小于或者等于T12时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T12且小于或者等于T10时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T10时，控制装置50控制灶具20关闭时停止发出报警声音。
在另外一个实施例中，锅具30处于无水烹饪状态时，防干烧温度阈值可设置为T13＝290℃。当报警温度阈值为一个时，报警温度阈值可设置为T14＝240℃。当锅具30的温度大于报警温度阈值T2时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，直至锅具30的温度大于防干烧温度阈值时，控制装置50控制灶具20关闭时停止发出报警声音。当报警温度阈值为两个时，报警温度阈值可设置为T14＝240℃及T15＝260℃。当锅具30的温度大于报警温度阈值T14且小于或者等于T15时，控制装置50可控制灶具20每隔60秒发出一次报警声音，每次报警声音持续3秒，报警声音为低频报警声音。当锅具30的温度大于报警温度阈值T15且小于或者等于T13时，控制装置50可控制灶具20每隔30秒发出一次报警声音，每次报警声音持续3秒，报警声音为高频报警声音，直至锅具30的温度大于防干烧温度阈值T13时，控制装置50控制灶具20关闭时停止发出报警声音。
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，本申请实施方式的控制方法可根据实际情况组合或者设计为其他的实施方式，在此不作限制。

请参阅图20及图21，控制方法包括：
步骤S410，采集锅具30的温度和灶具20的当前火力；
步骤S420，根据锅具30的温度确定灶具20的烹饪状态；
步骤S430，根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的防干烧温度阈值；

若锅具30的温度大于灶具20的报警温度阈值，步骤S480，控制灶具20发出与灶具20的报警温度阈值对应的报警信息。
本申请实施方式的防干烧系统100包括灶具20和控制装置50，控制装置50连接灶具20。作为例子，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，并应用于灶具20。
其中，本申请实施方式的防干烧的控制方法的步骤S410、步骤S420、步骤S430、步骤S440、步骤S450、步骤S460、步骤S470及步骤S480可以由控制装置50实现。也就是说，采集模块210用于采集锅具30的温度和采集模块210用于采集灶具20的当前火力；处理模块230用于根据锅具30的温度确定灶具20的烹饪状态；处理模块230用于根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的防干烧温度阈值；判断模块220用于判断锅具30的温度是否大于灶具20的防干烧温度阈值；若锅具30的温度大于灶具20的防干烧温度阈值，处理模块230用于控制灶具20关闭；处理模块230用于根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的报警温度阈值；判断模块220用于判断锅具30的温度是否大于灶具20的报警温度阈值；若锅具30的温度大于灶具20的报警温度阈值，处理模块230用于控制灶具20发出与灶具20的报警温度阈值对应的报警信息。其中，灶具20的防干烧温度阈值大于灶具20的报警温度阈值。
本申请实施方式的防干烧的控制方法及防干烧系统100中，根据灶具20的烹饪状态及灶具20的火力获取对应的灶具20的报警温度阈值和灶具20的防干烧温度阈值，及在锅具30的温度大于防干烧温度阈值时控制灶具20关闭，并在锅具30的温度大于报警温度阈值时控制灶具20发出与报警温度阈值对应的报警信息，如此，这样通过灶具20的烹饪状态及不同的灶具的火力可以获取更加准确的报警温度阈值和防干烧温度阈值以防止灶具20发生防干烧误判，并且灶具20在发生干烧之前或者刚开始发生干烧时可以及时通知用户注意灶具的烹饪情况，用户体验性好。
在图20的示例中，先判断锅具30的温度是否大于防干烧温度阈值，在锅具30的温度大于防干烧温度阈值时直接控制灶具20关闭而不会再去执行根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的报警温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，这样可以减少控制装置50的算法运算，提高执行效率。
而在锅具30的温度不大于防干烧温度阈值才会执行根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的报警温度阈值及判断锅具30的温度是否大于报警温度阈值的步骤，并且在锅具30的温度大于报警温度阈值发出与报警温度阈值对应的报警信息，而在锅具30的温度不大于报警温度阈值，则继续采集锅具30的温度，并重新判断锅具30的温度是否大于防干烧温度阈值，以此循环，随着锅具30的温度的逐渐升高，直到锅具30的温度大于防干烧温度阈值时控制灶具20关闭。
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可以给比例阀发送关闭指令，切断灶具20的供气，以使灶具20的燃烧器熄火。
需要指出的是，在控制灶具20关闭的同时，在一个实施例中，控制灶具20停止发出报警信息。在另一个实施例中，控制灶具20继续发出报警信息，而报警信息可以为提示灶具已关闭的语音，或者其他的提示方式提示灶具已关闭，在此不作限制。
需要说明的是，在另一个实施例中，可以先执行判断锅具30的温度是否大于报警温度阈值的步骤，在锅具30的温度大于报警温度阈值时控制灶具20发出报警信息，再去执行判断锅具30的温度是否大于灶具20的防干烧温度阈值，随着温度的逐渐升高，在锅具30的温度大于灶具20的防干烧温度阈值控制灶具20关闭。在控制灶具20关闭的同时，在一个实施例中，控制灶具20停止发出报警信息。在另一个实施例中，控制灶具20继续发出报警信息，而报警信息可以为提示灶具20已关闭的语音，或者其他的提示方式提示灶具20已关闭，在此不作限制。
在又一个实施例中，判断锅具30的温度是否大于报警温度阈值的步骤和判断锅具30的温度是否大于灶具20的防干烧温度阈值的步骤可以由控制装置50同时执行，这样可以快速根据锅具30的温度控制灶具20的状态。
具体地，在相关技术中，由于灶具20无论在何种火力下都是统一使用同一个防干烧温度阈值，这样使得容易导致灶具20小火时达到干烧启动温度阀值的干烧时间较长，灶具20在大火时容易出现防干烧误判，而且在灶具20发生干烧之前没有预警功能，不能引导用户及时对灶具20的烹饪情况做出处理。而在本申请实施方式中，可根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的报警温度阈值和灶具20的防干烧温度阈值，这样可以获取更加准确定的报警温度阈值和防干烧温度阈值，并且使得灶具20有预警功能，在灶具20接近干烧的状态下可以及时通知用户注意灶具20的烹饪情况，及在锅具30的温度大于防干烧温度阈值时可以控制灶具20关闭，用户体验性好。
请参阅图21，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。
请参阅图21，在某些实施方式中，灶具20包括火力检测传感器60，火力检测传感器60用于检测灶具20的火力。在一个实施例中，灶具20是燃气灶，火力检测传感器60可以是安装在灶具20开关旋钮柱上的可旋转式电位器，通过感知电位器的电阻、电压或电流变化获取灶具20火力调节档位，进一步判断出灶具20火力大小。在另一个实施例中，火力检测传感器60可以是安装在燃气管道上的燃气流速感应装置，通过感知燃气的流动速度判断出灶具20火力大小。在又一个实施例中，火力检测传感器60可以是安装在燃气管道上的燃气流速感应装置，通过感知燃气的流动速度判断出灶具20火力大小。在再一个实施例中，火力检测传感器60可以是安装在燃气管道上的燃气压力感应装置，通过感知燃气的压力判断出灶具20火力大小。当然，灶具20也可为电磁灶。电磁灶的火力可通过检测供给线圈的电流大小或火力档位来判断。
具体的，火力P可分为多个档位，如1挡、2档、3档、4档及5档等档位。在一个实施例中，火力P分为3个档位，1档为小火，2档为中火，3档为大火，第一预设火力为P1和第二预设火力为P2，如当检测到的火力P<P1时，判断当前火力为小火，当检测到的火力P1≤P≤P2时，判断当前火力为中火，当检测到的火力P>P2时，判断当前火力为大火。
请参阅图21及图22，在某些实施方式中，所述烹饪状态包括有水烹饪状态和无水烹饪状态，步骤S420包括：
步骤S422，根据所述锅具30的温度判断所述锅具30是否存在沸腾段，
若是，步骤S424，确定所述灶具20处于所述有水烹饪状态；
若否，步骤S426，确定所述灶具20处于所述无水烹饪状态。
上述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S422、步骤S424及步骤S426可以由控制装置50实现。也就是说，判断模块220用于根据所述锅具30的温度判断所述锅具30是否存在沸腾段，若是，处理模块230用于确定所述灶具20处于所述有水烹饪状态；若否，处理模块230用于确定所述灶具20处于所述无水烹饪状态。
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的外表面时锅具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为处于沸腾段。
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23，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24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，根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的报警温度阈值可以理解为，在一个实施例中，当灶具20处于有水烹饪状态时，建立灶具20的火力与灶具20的报警温度阈值的第一预设关系。当灶具20处于无水烹饪状态时，建立灶具20的火力与灶具20的报警温度阈值的第二预设关系。其中，而第一预设关系和第二预设关系可以分别表现为表格或者线条关系图等方式。
另外，根据灶具20的烹饪状态和灶具20的当前火力获取对应的灶具20的防干烧温度阈值可以理解为，在一个实施例中，当灶具20处于有水烹饪状态时，建立灶具20的火力与灶具20的防干烧温度阈值的第三预设关系。当灶具20处于无水烹饪状态时，建立灶具20的火力与灶具20的防干烧温度阈值的第四预设关系。其中，而第三预设关系和第四预设关系可以分别表现为表格或者线条关系图等方式。
在本申请实施方式中，灶具20的报警温度阈值与灶具20的火力正相关，也就是说，灶具20的火力越大，灶具20的报警温度阈值也就越大。灶具20的火力越小，灶具20的报警温度阈值也就越小。当灶具20的火力较大时，灶具20的报警温度阈值相应设置得比较高，这样可防止灶具20过早发出报警信息。当灶具20的火力较小时，灶具20的防干烧温度阈值也相应设置得比较低，这样可防止灶具20过晚发出报警信息。
另外，在本申请实施方式中，灶具20的防干烧温度阈值与灶具20的火力正相关，也就说，灶具20的火力越大，灶具20防干烧温度阈值也就越大。灶具20的火力越小，灶具20的防干烧温度阈值也就越小。当灶具20的火力较大时，灶具20的防干烧温度阈值也相应设置得比较高，这样可避免灶具20发生误判干烧而提前断火的情况。当灶具20的火力较小时，灶具20的防干烧温度阈值也相应设置得比较低，这样可以降低锅具30的温度达到防干烧温度阈值的时间，避免干烧时间过长。
需要说明的是，在同一火力下，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灶具20的防干烧温度阈值低于无水烹饪状态对应的灶具20的防干烧温度阈值，同样的，有水烹饪状态对应的灶具20的报警温度阈值低于无水烹饪状态对应的灶具20的报警温度阈值。
可以理解，本申请实施方式的控制装置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。
请参阅图21及图25，在某些实施方式中，步骤S422包括：
步骤S4522，判断采集到的锅具30的温度数量是否大于预设数量；
若是，步骤S524，计算预设时长内锅具30的温度的变化率；
步骤S4525，判断预设时长内锅具30的温度的变化率是否小于或等于预设值，若是，步骤S4526，确定锅具30存在沸腾段并将锅具30的当前温度作为锅具30的锅具沸腾温度；若否，步骤S4528，确定锅具30不存在沸腾段。
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S4522、步骤S4524、步骤S4525、步骤S4526及步骤S4528可以由控制装置50实现。也就是说，判断模块220用于判断采集到的锅具30的温度数量是否大于预设数量；若是，处理模块230用于计算预设时长内锅具30的温度的变化率；判断模块220用于判断预设时长内锅具30的温度的变化率是否小于或等于预设值，若是，处理模块230用于确定锅具30存在沸腾段并将锅具30 的当前温度作为锅具30的锅具沸腾温度；若否，处理模块230用于确定锅具30不存在锅具沸腾温度。
上述实施方式的控制方法通过计算预设时长内锅具30的温度的变化率来确定锅具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30的锅具沸腾温度。
需要说明的是，本实施方式中的预设时长内锅具30的温度的变化率可以由以下任一实施方式来获取。
预设时长内锅具30的温度与预设时长内锅具30的温度的平均值之差的绝对值之和；
预设时长内锅具30的温度对时间的斜率；
预设时长内锅具30的温度的方差；
预设时长内锅具30的温度的标准差。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度与预设时长内锅具30的温度的平均值之差的绝对值之和来获取。在一个实施例中，当采集到的锅具30的温度T k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，计算得到预设时长内锅具30的温度平均值与锅具30的单个温度Ti之差的绝对值之和可以表示为：SUB＝∑|Ti-Tmean|(i＝k-N至k)，SUB大则表示温度变化大。当SUB小于或者等于预设值时，则表示锅具30的温度变化小，可以认为锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，灶具20处于有水烹饪状态，将此时的锅具30的当前温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具30的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现SUB大于预设值，也认为锅具30是处于有水烹饪状态。
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，预设值可为10，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。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度对时间的斜率来实现。在一个实施例中，当采集到的锅具30的温度T k数量大于预设定值N时(即k＞N)，在预设时长的T k-N至T k的区间内，获取线性拟合T k-N至T k随时间变化的锅具30的温度对时间的斜率，即拟合得到y＝ax+b，如果a小于或者等于预设斜率，则判定锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，灶具20处于有水烹饪状态，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具30的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现a大于预设斜率，也认为锅具30是处于有水烹饪状态。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度的方差来实现。在一个实施例中，当采集的温度数据T k数量大于预设定值N时(即k＞N)，计算在预设时长中，T k-N至T k的区间内N+1个温度数据方差(VA)，VA大则表示锅具30的温度变化大。当VA小于或者等于预设值时(锅具30的温度变化小)，即锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具30的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现VA大于预设值，也认为锅具30是处于有水烹饪状态。
具体地，本实施方式中的预设时长内锅具30的温度的变化率可以由预设时长内锅具30的温度的标准差来实现。在一个实施例中，当采集的温度数据T k数量大于预设定值N时(即k＞N)，计算在预设时长中，T k-N至T k的区间内N+1个温度数据标准差(STD)，STD大则表示锅具30的温度变化大。当STD小于或者等于预设值时(锅具30的温度变化小)，即锅具30处于炖、煮、煲、蒸等有水烹饪状态且水分沸腾，将此时的温度数据T k作为锅具沸腾温度T b。需要指出的是，当将锅具30的当前温度T k作为锅具沸腾温度T b，也就是说，T b＝T k，此后，若出现STD大于预设值，也认为锅具30是处于有水烹饪状态。
请参阅图21及图26，在某些实施方式中，步骤S430包括：
步骤S432，当灶具20处于有水烹饪状态时，根据灶具20的当前火力获取第一报警温度值，将第一报警温度值设置为灶具20的报警温度阈值；
步骤S434，当灶具20处于无水烹饪状态时，根据灶具20的当前火力获取第二报警温度值，将第二报警温度值设置为灶具20的报警温度阈值。
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S432及S434可以由控制装置50实现。也就是说，处理模块230用于当灶具20处于有水烹饪状态时，根据灶具20的当前火力获取第一报警温度值，将第一报警温度值设置为灶具 20的报警温度阈值；当灶具20处于无水烹饪状态时，处理模块230用于根据灶具20的当前火力获取第二报警温度值，将第二报警温度值设置为灶具20的报警温度阈值；其中，第二报警温度值大于第一报警温度值。
具体地，当锅具30处于炖、煮、煲、蒸等有水烹饪状态时，锅具30达到干烧时锅具30的温度较低，因此在本实施方式中可根据灶具20的当前火力与灶具20的火力与报警温度阈值的第一预设关系获取第一报警温度值，并将第一报警温度值设置为灶具20的报警温度阈值。需要说明的是，第一报警温度值的数量可以为多个，也就是说，不同火力下对应不同的第一报警温度值。
当锅具30处于煎、炒、炸等无水烹饪状态，锅具30达到干烧时锅具30的温度较高，因此在本实施方式中可根据灶具20的当前火力与灶具20的火力与报警温度阈值的第二预设关系获取第二报警温度值，并将第二报警温度值设置为灶具20的报警温度阈值。需要说明的是，第二报警温度值的数量可以为多个，也就是说，不同火力下对应不同的第二报警温度值。
请参阅图21及图26，在某些实施方式中，步骤S450包括：
步骤S452，当灶具20处于有水烹饪状态时，根据灶具20的当前火力获取第一防干烧温度值，将第一防干烧温度值设置为灶具20的防干烧温度阈值；
步骤S454，当灶具20处于无水烹饪状态时，根据灶具20的当前火力获取第二防干烧温度值，将第二防干烧温度值设置为灶具20的防干烧温度阈值。
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S452及S454可以由控制装置50实现。也就是说，处理模块230用于当灶具20处于有水烹饪状态时，根据灶具20的当前火力获取第一防干烧温度值，将第一防干烧温度值设置为灶具20的防干烧温度阈值；当灶具20处于无水烹饪状态时，处理模块230用于根据灶具20的当前火力获取第二防干烧温度值，将第二防干烧温度值设置为灶具20的防干烧温度阈值；其中，第二防干烧温度值大于第一防干烧温度值。
具体地，当锅具30处于炖、煮、煲、蒸等有水烹饪状态时，锅具30达到干烧时锅具30的温度较低，因此在本实施方式中可根据灶具20的当前火力与灶具20的火力与防干烧温度阈值的第三预设关系获取第一防干烧温度值，并将第一防干烧温度值设置为灶具20的防干烧温度阈值。需要说明的是，第一防干烧温度值的数量可以为多个，也就是说，不同火力下对应不同的第一防干烧温度值。
当锅具30处于煎、炒、炸等无水烹饪状态，锅具30达到干烧时锅具30的温度较高，因此在本实施方式中可根据灶具20的当前火力与灶具20的火力与防干烧温度阈值的第四预设关系获取第二防干烧温度值，并将第二防干烧温度值设置为灶具20的防干烧温度阈值。需要说明的是，第二防干烧温度值的数量可以为多个，也就是说，不同火力下对应不同的第二防干烧温度值。
需要说明的是，在采集到的锅具30的温度数量小于或者等于预设数量，此时，采集到的锅具30的温度数量不足以确定灶具20具体的烹饪状态，在这种情况下，进入步骤S510，将第二报警温度值设置为灶具20的报警温度阈值，将第二防干烧温度值设置为灶具20的防干烧温度阈值。也就是说，以无水烹饪状态的控制策略来获取灶具20的报警温度阈值和防干烧温度阈值。
请参阅图27，在某些实施方式中，控制方法包括：步骤S4130，当灶具20处于有水烹饪状态时，根据锅具30的温度获取锅具30的导热性，根据灶具20的当前火力和锅具30的导热性获取对应的灶具20的报警温度阈值和灶具20的防干烧温度阈值。
上述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S4130可以由控制装置50实现。也就是说，控制装置50用于当灶具20处于有水烹饪状态时，根据锅具30的温度获取锅具30的导热性，根据灶具20的当前火力和锅具30的导热性获取对应的灶具20的报警温度阈值和灶具20的防干烧温度阈值。
如此，在灶具20处于有水烹饪状态时根据灶具20的当前火力和锅具30的导热性获取对应的报警温度阈值和防干烧温度阈值，这样可获取更加合适的报警温度阈值和防干烧温度阈值，以使灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判。
请参阅图21及图28，在某些实施方式中，步骤S4130包括：
步骤S4132，判断锅具30的锅具沸腾温度是否小于或者等于预设导热温度，
若是，步骤S4134，根据灶具20的当前火力和锅具30的导热性获取第三报警温度值并将第三报警温度值设置为灶具20的报警温度阈值；
若否，步骤S4136，根据灶具20的当前火力和锅具30的导热性获取第四报警温度值并将第四报警温度值设置为灶具20的报警温度阈值。
上述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S4132、S4134及S4136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30的锅具沸腾温度是否小于或者等于预设导热温度，若是，处理模块230用于根据灶具20的当前火力和锅具30的导热性获取第三报警温度值并将第三报警温度值设置为灶具20的报警温度阈值； 若否，处理模块230用于根据灶具20的当前火力和锅具30的导热性获取第四报警温度值并将第四报警温度值设置为灶具20的报警温度阈值；其中，第四报警温度值大于第三报警温度值。
请参阅图28，在某些实施方中，步骤S4130包括：
步骤S4132，判断锅具30的锅具沸腾温度是否小于或者等于预设导热温度，
若是，步骤S4135，根据灶具20的当前火力和锅具30的导热性获取第三防干烧温度值并将第三防干烧温度值设置为灶具20的防干烧温度阈值；
若否，步骤S4137，根据灶具20的当前火力和锅具30的导热性获取第四防干烧温度值并将第四防干烧温度值设置为灶具20的防干烧温度阈值。
上述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S4132、S4135及S4137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30的锅具沸腾温度是否小于或者等于预设导热温度，若是，处理模块230用于根据灶具20的当前火力和锅具30的导热性获取第三防干烧温度值并将第三防干烧温度值设置为灶具20的防干烧温度阈值；若否，处理模块230用于根据灶具20的当前火力和锅具30的导热性获取第四防干烧温度值并将第四防干烧温度值设置为灶具20的防干烧温度阈值；其中，第四防干烧温度值大于第三防干烧温度值。
如此，灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判。
具体地，在有水烹饪状态下，导热性越好的锅具30在烹饪时锅具沸腾温度Tb越小，因此，在同一灶具20的火力下，锅具30的导热性越好，所设置的防干烧温度阀值和报警温度阈值也就越低。需要说明的是，大火时锅具30的锅底温升速度最快，中火时锅具30的锅底温升速度次之，小火时锅具30的锅底温升速度最慢。由此可得，为了减少中火和小火时的干烧时间，可设置比大火时更低的防干烧温度阀值和报警温度阈值。也就是说，在同一锅具30的导热性下，灶具20的火力越小，所设置的防干烧温度阀值和报警温度阈值也就越低。
请参阅图23，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，在同一灶具20的火力下，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报警温度阈值和防干烧温度阈值，从而使得灶具20可以及时通知用户注意灶具20的烹饪状态及在灶具20达到防干烧状态时可以准确地启动防干烧功能，避免发生误判，用户体验性好。
在某些实施方式中，步骤S42包括：控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。
上述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。上述控制方法可以由控制装置50实现。也就是说，控制装置50用于控制灶具20每隔第一预设时长发出报警信息一次，每次报警信息持续第二预设时长。如此，这样可以快速并有效率地通知用户注意灶具20的烹饪情况。
具体地，在一个实施例中，报警信息可为灶具20的蜂鸣器发出的报警声音，报警声音可以每隔60秒报警一次，每次持续3秒。
在某些实施方式中，灶具20的报警温度阈值包括不同的多个报警温度阈值，多个报警温度值阈值与灶具20的防干烧温度阈值限定出多个报警范围，报警信息包括多个报警信息，每个报警范围对应一个报警信息；控制灶具20发出报警信息，包括：根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
上述控制方法可以由控制装置50实现。也就是说，控制装置50用于根据锅具30的温度所处的报警范围，控制灶具20发出与报警范围对应的报警信息。
如此，根据锅具30的温度所处的报警范围以控制灶具20发出与报警范围对应的报警信息，这样可以让用户通过对应的报警信息获知灶具20的干烧状态，以便于可以及时做出处理，用户体验性好。
具体的，在一个实施例中，灶具20的报警温度阈值分别包括第一报警温度阈值A和第二报警温度阈值B，其中，第一报警温度阈值A小于第二报警温度阈值B。第一报警温度阈值A、第二报警温度阈值B及灶具20的防干烧温度阈值C共同限定出两个报警范围[A，B)和[B，C]。当锅具30的温度处于报警范围[A，B)时，控制灶具20发出第一报警信息，例如，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度处于报警范围[B，C]，控制灶具20发出第二报警信息，例如，报警声音每隔30秒报警一次，每次持续3秒，随着锅具30的温度的持续升高，当锅具30的温度大于防干烧温度阈值时，可以控制灶具20关闭并停止发出报警信息。
在某些实施方式中，灶具20发出报警信息的频率与报警范围的温度正相关。具体地，报警范围的温度越高，灶具20发出报警信息的频率就频繁。在一个实施例中，当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒。当锅具30的温度落在[220，230)的报 警范围内时，报警声音每隔30秒报警一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒。
在某些实施方式中，报警信息包括声音，声音的频率与报警范围的温度正相关。具体地，报警范围的温度越高，声音的频率就越高。在一个实施例中，报警信息为报警声音。当锅具30的温度落在[210，220)的报警范围内时，报警声音每隔60秒报警一次，每次持续3秒，报警声音为低频声音。当锅具30的温度落在[220，230)的报警范围内时，报警声音每隔30秒报警一次，每次持续3秒，报警声音为中频声音。当锅具30的温度落在[230，240)的报警范围内时，报警声音每隔15秒报警一次，每次持续3秒，报警声音为高频声音。
在某些实施方式中，报警信息包括光，光的闪烁频率与报警范围的温度正相关。具体地，报警范围的温度越高，光的闪烁频率就越高。在一个实施例中，报警信息为报警显示灯发出的光。当锅具30的温度落在[210，220)的报警范围内时，报警显示灯每隔60秒闪烁一次，每次持续3秒。当锅具30的温度落在[220，230)的报警范围内时，报警显示灯每隔30秒闪烁一次，每次持续3秒。当锅具30的温度落在[230，240)的报警范围内时，报警显示灯每隔15秒闪烁一次，每次持续3秒。
需要说明的是，在锅具30的温度大于灶具20的当前报警温度值阈值时，在一个实施方式中，可以控制灶具20同时发出报警声音和闪烁报警显示灯。在另一实施方式中，只控制灶具20同时发出报警声音，例如发出预设的语音“请注意锅温，防止干烧”。在又一个实施方式中，只控制灶具20闪烁报警显示灯，例如，报警显示灯报警闪烁红光。报警的信息可根据用户的实际需求进行设置，在此不作限定。
具体地，在具体的实际应用场景中，根据锅具30所处的烹饪状态、锅具30的导热性及锅具30的当前火力获取对应的报警温度阈值及防干烧温度阈值。
