具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面结合附图来描述本发明实施例的分体式烹饪器具的控制方法以及分体式烹饪器具。
图1是根据本发明一个实施例的分体式烹饪器具的方框示意图。如图1所示，本发明实施例的分体式烹饪器具可包括底座10和器具本体20，器具本体20适于搁置在底座10上且相对底座10可分离。
在本发明的实施例中，分体式烹饪器具的底座10上可适于分别搁置多个不同类型的器具本体20，通过同一底座10与不同类型的器具本体20配合工作，可组成不同的烹饪器具。例如，器具本体20可以为普通锅具，通过底座10给普通锅具提供热源；器具本体20也可以为具有压力装置的压力锅锅体，通过与底座10组成分体式电压力锅；器具本体20还可以为具有煮饭装置的电饭煲煲体，通过与底座10组成分体式电饭煲等。这样可以利用一个底座实现多种不同的烹饪功能，从而能够减少对厨房空间的占用。
其中，底座10可直接连接到交流市电，而器具本体20可不用直接连接到交流市电，当器具本体20被搁置在底座10上时，底座10可为器具本体20提供电源或热源。具体地，底座10内可设有识别模块11、线圈盘12、无线发送线圈电路模块13和电磁炉控制模块14，当判断器具本体20搁置在底座10上时，电磁炉控制模块14可通过无线发送线圈电路模块13为器具本体20提供所需电能，可通过线圈盘12为器具本体20提供所需热能。由于器具本体20可以为普通锅具，也可以为压力锅锅体或者电饭煲煲体，并且对于不同的器具本体20所需的热能是不同的，所以需要对当前器具本体20进行准确且有效的检测，以防止当器具本体20实际上为压力锅锅体或电饭煲煲体时，但检测到的却是普通锅具，导致 底座10对压力锅锅体或电饭煲煲体进行持续加热，从而导致压力锅锅体或电饭煲煲体发生损坏或引起安全事故。
图2是根据本发明实施例的分体式烹饪器具的控制方法的流程图。如图2所示，本发明实施例的分体式烹饪器具的控制方法可包括以下步骤：
S1，在底座上电后，获取识别模块的状态信息。
根据本发明的一个实施例，识别模块包括干簧管，其中，干簧管闭合时对应第一状态，干簧管断开时对应第二状态。
举例而言，如图3所示，识别模块11可包括干簧管111和磁铁112，干簧管111设置在底座10中，磁铁112设置在器具本体20(如压力锅锅体或电饭煲煲体)中，当该器具本体20搁置在底座10上时，磁铁112将靠近干簧管111，使得干簧管111的簧片磁化，簧片的触点部分就会被磁力吸引，当吸引力大于簧片的弹力时，干簧管111的常开触点就会闭合，干簧管111将处于闭合状态，此时表示有压力锅锅体或电饭煲煲体搁置在底座10上；当器具本体20未搁置在底座10上时，干簧管111将处于断开状态，此时表示无压力锅锅体或电饭煲煲体搁置在底座10上。另外，由于普通锅具中未设置有磁铁112，所以当普通锅具搁置在底座10上时，干簧管111也将处于断开状态。因此，当干簧管111闭合时，有压力锅锅体或电饭煲煲体搁置在底座10上，此时为第一状态(即组合状态)；当干簧管111断开时，无器具本体20搁置在底座10上或者有普通锅具搁置在底座10上，此时为第二状态(即分离状态)。
S2，当识别模块的状态信息为第一状态时，禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行。
具体地，由于第一状态对应器具本体为压力锅锅体或电饭煲煲体，所以此时禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行。
S3，当识别模块的状态信息为第二状态时，判断无线发送线圈电路模块是否检测到反馈信号。
具体地，在识别模块的状态信息为第二状态时，还进一步判断底座中的无线发送线圈电路模块是否检测到反馈信号，以进一步确定底座上无压力锅锅体或电饭煲煲体。
举例而言，如图3所示，由于器具本体20可以不直接与交流市电连接，所以可以在器具本体20(如压力锅锅体或电饭煲煲体)中设置无线接收线圈电路模块21，以通过无线接收线圈电路模块21和无线发送线圈电路模块13进行电磁耦合以接收电能。由于无线电能传输需要无线接收线圈电路模块21和无线发送线圈电路模块13相互匹配且位置对应，所以还可以通过无线发送线圈电路模块来进一步确定底座上是否有压力锅锅体或电饭煲煲 体。
具体地，如图3所示，在电磁炉控制模块14检测到干簧管111断开时，还控制无线发送线圈电路模块13进行工作，即向无线发送线圈电路模块13中通入交流电，使得无线发送线圈电路模块13产生交变电磁场，无线接收线圈电路模块21在交变电磁场的作用下产生感应电动势，此时器具本体20中的电饭煲控制模块22将获得电能，并发送一个反馈信号至无线接收线圈电路模块21，通过无线接收线圈电路模块21耦合传输至无线发送线圈电路模块13。无线发送线圈电路模块13实时检测该反馈信号，以根据该反馈信号来确定底座上是否有压力锅锅体或电饭煲煲体。
S4，如果无线发送线圈电路模块检测到反馈信号，则禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行。
S5，如果无线发送线圈电路模块未检测到反馈信号，则允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。
具体而言，如图3所示，当无线发送线圈电路模块13检测到反馈信号时，说明底座10上搁置有压力锅锅体或电饭煲煲体，识别模块11可能失效，此时电磁炉控制模块14禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行；当无线发送线圈电路模块13未检测到反馈信号时，说明在识别模块11和无线发送线圈电路模块13的双重检测下都未检测到有压力锅锅体或电饭煲煲体，此时可允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。也就是说，当通过识别模块和无线发送线圈电路模块均未检测到有压力锅锅体或电饭煲煲体时，才允许使用电磁炉工作模式，从而有效避免采用单一识别方式在失效情况下，造成无法检知组合状态(压力锅锅体或电饭煲煲体搁置在底座上)而处于电磁炉工作模式对器具本体持续加热的安全问题。
根据本发明的一个实施例，底座内还设有第一无线通信模块，其中，在禁止底座以电磁炉工作模式运行、并允许底座以电饭煲工作模式运行时，无线发送线圈电路模块与当前搁置在底座上的器具本体中的无线接收线圈电路模块建立无线供电连接，第一无线通信模块与器具本体中的第二无线通信模块建立无线通信连接以实现当前搁置在底座上的器具本体与底座进行通信数据交互，并根据当前搁置在底座上的器具本体与底座进行通信数据交互对线圈盘进行加热控制。
具体而言，如图4所示，底座10中还设置有第一无线通信模块15，同时器具本体20(如压力锅锅体或电饭煲煲体)中还设置有第二无线通信模块23，第一无线通信模块15和第二无线通信模块23可以为红外通信模块等。
当电磁炉控制模块14通过识别模块11和无线发送线圈电路模块13判断器具本体20 为压力锅锅体或电饭煲煲体时，电磁炉控制模块14将禁止底座以电磁炉工作模式运行、并允许底座以电饭煲工作模式运行，此时电磁炉控制模块14向无线发送线圈电路模块13中通入交流电，使得无线发送线圈电路模块13产生交变电磁场，无线接收线圈电路模块21在交变电磁场的作用下产生感应电动势，以给器具本体20中的电饭煲控制模块22供电。然后，电饭煲控制模块22控制第二无线通信模块23与第一无线通信模块15建立无线通信连接，以将相关加热数据信息传输给电磁炉控制模块14，以使电磁炉控制模块14根据接收到的相关加热数据信息对线圈盘12进行加热控制，如控制线圈盘12对器具本体20中的锅进行诱导加热。
根据本发明的一个实施例，在允许底座以电磁炉工作模式运行、并禁止底座以电饭煲工作模式运行时，控制线圈盘以电磁炉工作模式进行加热。
具体而言，如图4所示，当电磁炉控制模块14通过识别模块11和无线发送线圈电路模块13判断无器具本体20或器具本体20为普通锅具时，电磁炉控制模块14允许底座以电磁炉工作模式运行、并禁止底座以电饭煲工作模式运行，此时控制线圈盘12以电磁炉工作模式进行加热。其中，需要说明的是，在控制线圈盘12以电磁炉工作模式(如谐振加热)进行加热时，先检测当前底座上是否有普通锅具存在，如果有，则再进行加热；否则，禁止加热。
图5是根据本发明一个实施例的分体式烹饪器具的控制方法的流程图。如图5所示，该分体式烹饪器具的控制方法可包括以下步骤：
S101，底座上电。
S102，电磁炉控制模块驱动无线发送线圈电路模块运作，并检测干簧管的状态。
S103，判断干簧管是否闭合。如果是，执行步骤S104；如果否，执行步骤S105。
S104，禁止电磁炉工作模式，并允许电饭煲工作模式。
S105，判断无线发送线圈电路模块是否检测到反馈信号。如果是，返回步骤S104；如果否，执行步骤S106。
S106，允许电磁炉工作模式，并禁止电饭煲工作模式。
因此，根据本发明实施例的分体式烹饪器具的控制方法，通过识别模块和无线发送线圈电路模块这两种方式实现信号耦合，从而实现器具本体与底座的分离和组合检测，进而确定正确的工作模式，有效避免了单一识别方式在失效情况下，造成无法检知组合状态而处于电磁炉工作模式对器具本体持续加热的安全问题。而且，在禁止电磁炉工作模式，并允许电饭煲工作模式时，第一无线通信模块和第二无线通信模块之间还进行了信号耦合，所以也可以进一步根据第一无线通信模块和第二无线通信模块来实现器具本体与底座的分 离和组合检测，即通过三种方式进行共同检测，大大提高了检测的可靠性，保证了分体式烹饪器具工作的安全性。
进一步地，根据本发明的一个实施例，在底座上电后，如果无线发送线圈电路模块处于关闭状态，则在识别模块的状态信息为第二状态时，控制线圈盘输出加热检锅信号，并根据加热检锅信号判断底座上当前是否有锅，其中，如果底座上当前有锅，则控制无线发送线圈电路模块进行工作，以判断无线发送线圈电路模块是否检测到反馈信号；如果底座上当前无锅，则允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。
具体而言，如图4所示，在电磁炉控制模块14检测到干簧管111断开时，正常情况下存在两种可能，一种是器具本体20为普通锅具，另一种是底座10上无器具本体20，所以此时可先控制线圈盘12输出加热检锅信号，以判断底座10上是否有锅具。如果有，则控制无线发送线圈电路模块13进行工作，即向无线发送线圈电路模块13中通入交流电，使得无线发送线圈电路模块13产生交变电磁场，无线接收线圈电路模块21在交变电磁场的作用下产生感应电动势，此时器具本体20中的电饭煲控制模块22将获得电能，并发送一个反馈信号至无线接收线圈电路模块21，通过无线接收线圈电路模块21耦合传输至无线发送线圈电路模块13。无线发送线圈电路模块13实时检测该反馈信号，电磁炉控制模块14根据该反馈信号来进一步确定底座上是否有压力锅锅体或电饭煲煲体。如果底座10上没有锅具，则允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。
也就是说，在通过无线发送线圈电路模块来进一步判断器具本体是否为压力锅锅体或电饭煲煲体之前，还对底座上是否有锅进行检测，如果有锅，则再根据无线发送线圈电路模块判断器具本体是否为压力锅锅体或电饭煲煲体，从而可以有效避免分体式烹饪器具在待机情况下运行无线检测导致功耗偏高的问题。
进一步地，图6是根据本发明另一个实施例的分体式烹饪器具的控制方法的流程图。如图6所示，该分体式烹饪器具的控制方法可包括以下步骤：
S201，底座上电。
S202，电磁炉控制模块运行，并检测干簧管的状态。
S203，判断干簧管是否闭合。如果是，执行步骤S208；如果否，执行步骤S204。
S204，电磁炉控制模块定时(如10s～1min)驱动线圈盘输出短时间(如1～2s)的加热检锅信号。
S205，判断是否检出有锅。如果是，执行步骤S206；如果否，执行步骤S209。
S206，电磁炉控制模块驱动无线发送线圈电路模块向无线接收线圈电路模块供电。
S207，判断无线发送线圈电路模块是否检测到有反馈信号。如果是，执行步骤S208；如果否，执行步骤S209。
S208，禁止电磁炉工作模式，并允许电饭煲工作模式。
S209，允许电磁炉工作模式，并禁止电饭煲工作模式。
综上所述，根据本发明实施例的分体式烹饪器具的控制方法，在底座上电后，获取识别模块的状态信息，当识别模块的状态信息为第一状态时，禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行；当识别模块的状态信息为第二状态时，判断无线发送线圈电路模块是否检测到反馈信号。如果无线发送线圈电路模块检测到反馈信号，则禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行；如果无线发送线圈电路模块未检测到反馈信号，则允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。该方法能够有效识别出底座与器具本体的分离/组合状态，有效避免了单一识别方式在失效情况下，造成无法检知组合状态而处于电磁炉工作模式对器具本体持续加热的安全问题。
下面来详细描述本发明实施例的分体式烹饪器具。
如图1所示，本发明实施例的分体式烹饪器具可包括底座10和器具本体20，器具本体20适于搁置在底座10上且相对底座10可分离，底座10内设有识别模块11、线圈盘12、无线发送线圈电路模块13和电磁炉控制模块14，电磁炉控制模块14在底座10上电后获取识别模块11的状态信息，其中，当识别模块11的状态信息为第一状态时，电磁炉控制模块14禁止底座10以电磁炉工作模式运行，并允许底座10以电饭煲工作模式运行；当识别模块11的状态信息为第二状态时，电磁炉控制模块14判断无线发送线圈电路模块13是否检测到反馈信号；如果无线发送线圈电路模块13检测到反馈信号，电磁炉控制模块14则禁止底座10以电磁炉工作模式运行，并允许底座10以电饭煲工作模式运行；如果无线发送线圈电路模块13未检测到反馈信号，电磁炉控制模块14则允许底座10以电磁炉工作模式运行，并禁止底座10以电饭煲工作模式运行。

根据本发明的一个实施例，在底座10上电后，如果无线发送线圈电路模块13处于关闭状态，则在识别模块11的状态信息为第二状态时，电磁炉控制模块14控制线圈盘12输出加热检锅信号，并根据加热检锅信号判断底座10上当前是否有锅，其中，如果底座10上当前有锅，电磁炉控制模块14则控制无线发送线圈电路模块13进行工作，以判断无线发送线圈电路模块13是否检测到反馈信号；如果底座10上当前无锅，电磁炉控制模块14则允许底座10以电磁炉工作模式运行，并禁止底座10以电饭煲工作模式运行。
根据本发明的一个实施例，如图4所示，底座10内还设有第一无线通信模块15，其中，在电磁炉控制模块14禁止底座10以电磁炉工作模式运行、并允许底座10以电饭煲工作模 式运行时，无线发送线圈电路模块13与当前搁置在底座10上的器具本体20中的无线接收线圈电路模块21建立无线供电连接，第一无线通信模块15与器具本体20中的第二无线通信模块23建立无线通信连接以实现当前搁置在底座10上的器具本体20与底座10进行通信数据交互，当前搁置在底座10上的器具本体20中的电饭煲控制模块22根据当前搁置在底座10上的器具本体20与底座10进行通信数据交互对线圈盘12进行加热控制。
根据本发明的一个实施例，在允许底座10以电磁炉工作模式运行、并禁止底座10以电饭煲工作模式运行时，电磁炉控制模块14控制线圈盘12以电磁炉工作模式进行加热。
需要说明的是，本发明实施例的分体式烹饪器具中未披露的细节，请参照本发明实施例的分体式烹饪器具的烹饪控制方法中所披露的细节，这里不再赘述。
根据本发明实施例的分体式烹饪器具，在烹饪器具的底座内设置识别模块、线圈盘、无线发送线圈电路模块和电磁炉控制模块，电磁炉控制模块在底座上电后获取识别模块的状态信息，其中，当识别模块的状态信息为第一状态时，电磁炉控制模块禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行；当识别模块的状态信息为第二状态时，电磁炉控制模块判断无线发送线圈电路模块是否检测到反馈信号。如果无线发送线圈电路模块检测到反馈信号，电磁炉控制模块则禁止底座以电磁炉工作模式运行，并允许底座以电饭煲工作模式运行；如果无线发送线圈电路模块未检测到反馈信号，电磁炉控制模块则允许底座以电磁炉工作模式运行，并禁止底座以电饭煲工作模式运行。该分体式烹饪器具能够有效识别出底座与器具本体的分离/组合状态，有效避免了单一识别方式在失效情况下，造成无法检知组合状态而处于电磁炉工作模式对器具本体持续加热的安全问题。
