具体实施方式
下面结合附图和实施例，对本发明的具体实施方式做进一步描述。以下实施例仅用于说明本发明，但不用来限制本发明的范围。
图1示出了本发明实施例1提供一种用于电烹饪锅的无线供电通讯电路，包括：设置在锅体上的锅体控制单元和第一线圈(图中未标出)，以及设置在上盖上的第二线圈谐振电路和上盖控制单元，所述锅体控制单元包括控制器、发热组件、电源板和解调模块，所述电源板连接所述控制器，所述控制器连接所述发热盘、所述第一线圈和所述解调模块，所述解调模块连接所述第一线圈。所述上盖控制单元包括整流模块3、功能器件4、处理芯片和载波通讯模块，所述整流电路与第二线圈谐振电路连接，所述功能器件与所述处理芯片均与整流模块连接，所述功能器件和所述处理芯片连接；所述处理芯片与所述载波通讯模块连接；所述载波通讯模块与所述第二线圈谐振电路连接。所述第二线圈谐振电路包括第二线圈1，以及连接在第二线圈的两端且相互并联设置的至少一个第一电容，在图1中所示为一个第一电容C1，或者，如实施例2中图2所示，所述第二线圈谐振电路包括第二线圈、连接在第二线圈的两端且相互并联设置的至少一个第一电容C1，以及与所述第一电容串联的第二电容C3。其中，
第一线圈，与控制器连接，控制器与电源板连接，第一线圈与控制器连接，从而获得工作电压。所述第一线圈与所述第二线圈同轴设置，用于在通电过程中与所述第二线圈、第一电容发生电磁感应使第二线圈产生电流或电 压。
第二线圈谐振电路5，与整流模块连接，经过整流处理使交流电转化为直流电后将电流或电压传输给功能器件、处理芯片和载波通讯模块，以使功能器件、处理芯片和载波通讯模块进行工作。其中，所述功能器件包括包括上盖感温器，电磁阀，电磁线圈、显示屏等现有存在的功能器件的一种或多种。
本发明通过第一线圈、第二线圈和第一电容进行电磁感应现象，从而产生可以供给功能器件和处理芯片所需的电流或电压，实现了锅体向上盖无线供电。
烹饪锅在烹饪过程中需按照烹饪信号作出相应的工作。上盖上的负载在工作过程中会产生烹饪状态信号，烹饪锅在工作状态下会发出相应烹饪指令信号，处理芯片获取这些信号后需反馈到锅体上的控制器，控制器经过对这些信号的解读获得烹饪信号，并根据信号做出相应的控制指令。因此为了实现锅体与上盖之间无线传输信号，可通过载波方式利用波形变化获取通讯信号。因此，本发明可将信号发送给载波通讯模块。
该载波通讯模块与所述第二线圈谐振电路连接，用于接收到数据信息后作用于第二线圈谐振电路，改变第一线圈与第二线圈谐振电路发生电磁感应时产生的电流或电压谐振波振幅(如图3所示)，其中图中发射线盘为第二线圈。如图3所示的电流或电压谐振波振幅处于变化状态，解调模块与第一线圈连接，可在电路供电及通讯过程中获取第一线圈和第二线圈谐振电路发生电磁感应时产生的电流或电压谐振波变化信号，并解调为烹饪信号。最终将烹饪信号反馈到控制器。
如图1所示，所述载波通讯模块2包括第一MOS管Q1和第一谐振电容C2，所述第一MOS管的G极与所述处理芯片的信号输出端连接，所述第一MOS管的S极接地，所述第一MOS管的D极连接所述第一谐振电容的一端，所述第一谐振电容的另一端连接第二线圈谐振电路当中，在图中，第一谐振电容与第一电容连接，其中，
所述第一MOS管接收所述数据信号从而使其导通，导通后会使第一谐振电容处于第二线圈谐振电路的工作电路当中，第一谐振电容参与第一线圈和 第二线圈所产生电流或电压的谐振工作，从而改变了第一线圈和第二线圈供电过程下谐振波的振幅。
进一步地解释说明，还包括一分流电阻，所述分流电阻的一端连接所述第一MOS管的G极，所述分流电阻的另一端连接所述上盖电器件的信号输出端。
更进一步地解释说明，还包括一第一电阻，所述第一电阻的一端连接所述第一MOS管的G极，所述第一电阻的另一端接地。当电路出现故障时，该第一电阻可禁止第一MOS管处于导通状态。
本发明在发送数据时，开启第一MOS管，使第一谐振电容参与谐振，从而谐振状态发生变化，造成谐振波振幅发生变化，进一步被解调，达到信号反馈目的。
本发明使用相对设置的线圈进行电磁感应产生电流或电压。并通过检测谐振波振幅的改变实现信息的交互，从而同时解决现有技术中无法同时无线供电和通讯的问题。
实施例3：如图4所示，本发明提供一种用于电烹饪锅的无线供电通讯方法，包括：
S1、使第一线圈通电后和第二线圈谐振电路进行电磁感应向上盖控制单元传输电流或电压；
S2、所述上盖控制单元通电工作后向载波通信模块发送数据信号；
S3、上盖控制单元通电工作后发送数据信号作用于所述第二线圈谐振电路，改变第二线圈谐振电路与第一线圈发生电磁感应时产生的电流或电压谐振波振幅；
S4、锅体控制单元在电路供电及通讯过程中获取第一线圈与第二线圈谐振电路发生电磁感应时产生的电流或电压谐振波变化信号，并解调为烹饪信号。
本发明使用相对设置的线圈进行电磁感应产生电流或电压。并通过检测谐振波振幅的改变实现信息的交互，从而同时解决现有技术中无法同时无线供电和通讯的问题。
实施例4：本发明提供一种电烹饪锅，包括上述无线供电通讯电路。在本实施例中，只要在电烹饪锅上设置有无线供电通讯电路，并能够实现无线传输电力或信号即可。
实施例5：如图5-图7所示，本发明实施例5提供一种电烹饪锅，包括：锅体6、上盖7和上述无线供电通讯电路(图中未画出)，其中，在所述锅体6上设置一铰接轴12，一插接座8与铰接轴12铰接，所述上盖7上设置有一插接腔9，所述插接座与所述插接腔配合插合；在所述插接座8上设置有第一线圈10，在所述插接腔9内或靠近插接腔位置处设置有第二线圈谐振电路5；在所述锅体上设置有锅体控制单元(图中未画出)，在所述上盖上设置有上盖控制单元(图中未画出)。本实施例根据实施例1所述的无线电路通讯电路实现上盖与锅体之间无线传输电力和信号。在此不再赘述。
进一步地解释说明，所述插接座包括座台13，所述座台与铰接轴铰接，在所述座台上方设置有垂直于座台平面的插头14。所述插接腔包括座台腔15和插头腔11，所述座台腔15与所述座台13配合插合，所述插头腔11与所述插头14配合插合。座台与座台腔的插合可增加上盖与插接在插接座上的稳定性，插头与插头腔的插合可增加两个线圈的感应稳定性。可将锅体第一线圈设置在所述插头内，插头插接在插头腔内，感应过程较稳定，又由于其在整个腔体内部，防水效果较好，使用寿命较长。
如图12所示，本发明利用线圈之间的电磁感应原理，使上盖第二线圈谐振电路产生电流，供电给上盖电器件。同时上盖电器件的信号反馈给锅体上的控制板。另外，需要说明的是，为了便于锅体与上盖的开合使用方便，所述插接座绕所述铰接轴的旋转角度为0-95°。上盖可随铰链座摆动至水平位置合盖，开盖时亦可随铰链座摆置95°位置，上盖可轻松拆出。
本实施例1所述的电烹饪锅，插接座铰接在锅体上，能够在一定角度范围内自由转动，同时上盖上的插接腔插接在插接座上，使上盖可以在与锅体盖合或打开状态下均能够完成无线传输电力或信号。
实施例6：如图8-图9所示，本发明所述一种电烹饪锅，本实施例与实施 例5不同的地方在于：所述插接座8是固定在锅体边缘上。上盖在合盖状态时，可通过插接腔插接在插接座上，能够在开盖状态下实现烹饪的功能。
实施例7：如图10-图11所示，本发明所述一种电烹饪锅，本实施例与实施例5不同的地方在于：所述插接座8是固定在锅体边缘上。上盖在合盖状态下，可通过插接腔插接在插接座上，实现合盖状态下的烹饪功能。
实施例8：本发明所述一种电烹饪锅，本实施例可在上盖上设置两个插接腔(图中未示出)，一个用来在上盖盖在锅体上时插接在插接座上实现合盖状态下的烹饪功能，另一个用来在上盖开盖状态下的烹饪功能。
实施例9：本发明所述电烹饪锅，为了防止上盖过于轻松从锅体上滑落，所述插接座与所述插接腔可通过可活动卡合方式连接。具体可为：在所述插接腔内设有卡槽(图中未示出)，在所述插接座表面设有弹性卡头，所述弹性卡头与所述卡槽卡合。即便存在上述卡头和卡槽，但由于具有弹性功能，因此，上盖依然可从锅体上拆出。
以上实施方式仅用于说明本发明，而并非对本发明的限制，有关技术领域的普通技术人员，在不脱离本发明的精神和范围的情况下，还可以做出各种变化和变型，因此所有等同的技术方案也属于本发明的保护范畴。
