具体实施方式
以下结合附图对本发明实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明实施例，并不用于限制本发明实施例。
本技术领域技术人员可以理解，本发明的说明书中使用的措辞“包括”及“包含”是指存在上述特征、整数、步骤、操作、元件和/或组件，但是并不排除存在或添加一个或多个其他特征、整数、步骤、操作、元件、组 件和/或它们的组合。应该理解，当我们称元件被“连接”到另一元件时，它可以直接连接到其他元件，或者也可以存在中间元件。此外，这里使用的“连接”可以包括无线连接。这里使用的措辞“和/或”包括一个或更多个相关联的列出项的全部或任一单元和全部组合。
参见图2示出的是本发明一实施例的用于电磁加热锅具的加热控制方法的流程示意图，该加热控制方法包括：
步骤101：获取关于电磁加热锅具在加热过程中的工作加热参数，其中工作加热参数包含选自以下中的一者或多者：上盖检测温度、工作电流、检锅脉冲次数。
更具体的，可以是通过参数采集器来采集工作加热参数，并从该参数采集器来获取该工作加热参数，举例而言，该参数采集器可以是温度传感器(例如上盖温度传感器)、电流计等。可以理解的是，所获取的工作加热参数可以是上盖检测温度(例如可以指示电磁加热锅具的腔体内靠近上盖处的蒸汽在工作状态下的温度信息)、工作电流、检锅脉冲次数其中的任意一个或任意的组合，该所选定的此一种或多种工作加热参数可以在一定程度上反映出IH锅具的工作加热状态是否正常。
步骤102：当所获取的工作加热参数与预设定的加热异常规则相匹配时，触发控制降低对电磁加热锅具的内锅的加热量。
更具体的，加热异常规则指代的是IH锅具在非正常工作状态下所对应的规则，其可以是与加热正常规则相对立或互补的，例如可以是预先确定IH锅具在正常加热工作状态下时所满足的条件为加热正常规则，然后可以将不满足加热正常规则的其他条件确定为上述加热异常规则，例如，在正常状态下，上盖检测温度的温升速率范围为(2-4)AD值/分钟，工作电流的范围为85H-8BH(十六进制的AD值)，检锅脉冲次数的范围为2-3次，相应的，加热异常规则则可以是，在IH锅具的底部温度传感器与内锅之间不能直接接触时，上盖检测温度的温升速率范围为小于等于1.5AD值/分钟， 工作电流的范围为小于等于80H(十六进制的AD值)，检锅脉冲次数的范围为大于等于4次，由此可以借助于加热异常规则来实现判断IH锅的正常或异常的电磁加热状态。以及，该工作加热参数与加热异常规则的匹配工作的实施可以是直接的对比匹配，也可以是基于工作加热参数在经过数据优化处理之后(更具体地将在下文展开)再与加热异常规则的对比匹配，且都应当属于本实施例的保护范围。需要说明的是，此处工作电流的数据是这样体现的：在控制电路中串联一个阻值微小的电阻，检测该电阻两端电压的AD值，通过该检测到的电压AD值来反映控制电路中的工作电流大小，工作电流越大，检测的电压AD值越大。
在异常情况下，内锅距离IH加热线圈的距离变远，导致IH锅具整机的电感参数会变大，IH加热线圈的电阻参数会变小，进而导致加热功率降低、LC谐振电路的能量损失变小。一方面加热功率降低会使得上盖检测温度的温升速率变慢；另一方面为了保证加热功率的恒定，IH锅具中的IGBT开通时间会延长，使得控制电路中的工作电流会变小；再一方面LC谐振电路的能量损失变小，使得检锅脉冲次数变多。由此，通过获取IH锅具在加热过程中的上盖检测温度、工作电流和/或检锅脉冲次数的工作加热参数，可以实时判断IH锅具是否工作异常。
需要说明的是，由于现有技术中电磁加热锅具的程序控制所考虑的参数一般也只是底座传感器所检测到的锅底温度，通过判断锅底温度上升的速度是否大于预定的值来判定IH锅具是否处于内锅中没有水分的干烧状态，但是无法判定IH锅具是否存在底部温度传感器脱落或者IH锅具中内锅被抬起的故障。而本申请的发明人在实践本申请的过程中发现可以将锅底温度以外的其他参数(如上文所阐述的上盖检测温度、工作电流、检锅脉冲次数)考虑至电磁加热锅具的程序判断和控制中，并相应地改进硬件(例如可以添加电流计或额外的传感器来获取上述其他参数)和软件(例如可以对所检测的参数执行优化处理、判断操作等)，并且在本实施例中更 具体的可以是利用上述其他参数来考量电磁加热锅具是否正常工作。
作为本实施例进一步的公开和优化，当所获取的工作加热参数与预设定的第二加热异常规则相匹配时，触发控制停止加热内锅。应当理解的是，该第二加热异常规则可以是IH锅具加热严重异常时所对应的条件，由此使得在IH锅具处于加热严重异常的工作状态下时能够停止对内锅的加热，将IH锅具的加热安全隐患降至最低。
参见图3示出的是本发明另一实施例的用于电磁加热锅具的加热控制方法的流程示意图，该加热控制方法包括：
步骤201：获取关于电磁加热锅具在加热过程中的工作加热参数，其中该工作加热参数包含锅底检测温度以及工作加热参数还包含选自以下中的一者或多者：上盖检测温度、工作电流、检锅脉冲次数。
步骤202：将所获取的上盖检测温度、工作电流、检锅脉冲次数中的一者或多者、连同锅底检测温度与预设定的加热异常规则进行匹配，以确定工作加热参数与预设定的加热异常规则是否相匹配；以及当该匹配的结果为是时，触发加热量降低控制步骤。
步骤203：控制降低加热量，包括，控制降低输入至电磁加热锅的IGBT的控制信号的占空比，以降低包含以下对内锅实施的加热量中一者或多者：来自于电磁加热锅具的上盖的加热量、内锅侧面加热量和内锅底部加热量。
关于本实施例方法的执行可以是在IH锅具的控制芯片上所完成的；关于步骤201和步骤202实施的部分细节可以参照对图1所示实施例的描述，故在此不加以赘述；但仍存在区别在于：在本实施例中的步骤201中所选用的工作加热参数还将锅底检测温度作为判定锅具是否处于正常加热状态的一个辅助因素，由此可以进一步地保障所确定的锅具加热状态的精确性。更具体的是，加热异常规则是与加热正常规则相对立的，而加热正常规则所指代的是正常状态下IH锅具应当具有的锅底温度、上盖温度、工作电流和/或内锅检锅。需要强调的是，虽然当底部传感器脱离了内锅时，其所检 测到的温度信息并不能准确反应锅底温度，但其应当还是能检测到实时温度参数的，可以通过检测正常工作状态下关于锅底温度的正常锅底温度区间，并利用该正常锅底温度区间来对所检测的锅底温度进行判断比对也是可以在一定程度上判断出加热锅具正常或异常状态的。步骤203是在步骤202触发降热步骤之后的执行降热步骤，其利用了设置在电磁加热锅具中的IGBT(Insulated Gate Bipolar Transisto，绝缘栅双极型晶体管)，并且该IGBT可以接收自控制芯片所输入的控制信号而实施对内锅的加热操作，包含了来自IH锅具的上盖的加热、内锅侧面的加热和内锅底部其中一处或多处的加热；更具体地，可以是在满足触发控制条件之后，控制芯片控制降低输入至IGBT的控制信号的占空比，由此来实现在检测到IH锅具工作异常时而实时降低对IH锅具的加热量。
参见图4示出的是本发明又一实施例的用于电磁加热锅具的加热控制方法的流程示意图，IH锅具进入工作过程准备开始，之后进入加热阶段；当处于加热阶段时，首先判断是否已经超过预设定的加热阶段时间，当确定已经超过预设定的加热阶段时间时直接跳转到下一阶段，也就是沸腾阶段；当确定还没有超过预设定的加热阶段时间时，执行对电磁加热锅具的加热控制。更具体地，可以是检测锅底温度、上盖温度、工作电流和内锅检测次数，关于内锅检锅次数的检测可以是基于检测内锅相对于加热线圈的电感量来确定的，可以理解的是，底部传感器与内锅之间接触的分离会导致该电感量的改变。其中，锅底温度、上盖温度、工作电流和内锅检测次数的检测可以是如上所述的通过控制芯片与所连接的传感器或电流计的连接来实现的；可以预见到的是，所有具有温度检测功能的目前已有的或将来的设备或产品都应被理解为本发明实施例中的温度传感器。
然后，将所获取的锅底温度、上盖温度、工作电流和内锅检测次数其中的一者或多者(例如可以就只是上盖温度、也可以是上盖温度和工作电流、还可以是工作电流与内锅检测次数等)与其相应的加热异常规则进行 匹配，由此来确定IH锅是否工作正常。作为示例，当在加热阶段的某一时刻所检测到的温度参数与预先确定好的在正常加热状态下加热阶段的该时刻所对应的正常温度参数或区间不同(或者与该正常温度参数或区间相互补的异常温度参数或区间相同)时，则可以认定此时刻的IH锅具加热异常。对于上述加热异常判断过程的在数据处理方面的改进和优化也应当属于本发明实施例的范围，通过基于一段时间内所检测的锅底温度、上盖温度、工作电流和内锅检测次数的差值来确定锅底温度变化、上盖温度变化、工作电流变化率和/或内锅检锅次数变化，并基于该经转换之后的关于IH锅具的工作加热参数来完成与工作参数异常区间的匹配工作。
当判断IH锅具加热异常(也就是匹配于工作参数异常区间)时，降低输入至IGBT的占空比以降低对IH锅具的加热量；当判断IH锅具加热正常时，则可以跳转至判断加热阶段的时间是否超过，并循环执行工作异常的匹配判断步骤直到超过加热阶段时间。如图4所示，IH锅具在沸腾阶段也可以执行与其在加热阶段相同的工作异常判断步骤，相同内容在此不加以赘述。IH锅的加热方式一般为三维立体的加热方式，也就是实现从内锅的底盘、侧面和上盖全方位加热，基于所输入至IGBT的占空比能够调整降低从内锅的底盘、侧面和/或上盖对内锅的加热量。
本发明实施例还提供一种机器可读存储介质，该机器可读存储介质上存储有指令，该指令用于使得机器执行本申请上述实施例方法的步骤。

关于本发明实施例中的相关单元或模块功能的实现，其可以是直接集成在控制芯片上的，也可以是集成在于控制芯片和与其相关联的辅助设备上的；以及关于本发明装置实施例的更具体的细节，可以参照上文电磁加 热锅具的加热控制方法实施例的描述，故在此不加以赘述。
