具体实施方式
以下结合附图对本发明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，并不用于限制本发明。
需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互组合。
下面将参考附图并结合实施例来详细说明本发明。
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、顶、底”通常是针对附图所示的方向而言的或者是针对竖直、垂直或重力方向上而言的各部件相互位置关系描述用词。方位词如“内、外”指的是腔室 内外或锅体内外。
如图1所示，本发明提供了一种带搅拌功能的上盖，其包括盖体总成和搅拌器组件，盖体总成内设有旋转电机1，该旋转电机1的输出轴11向下伸出以驱动搅拌器组件的旋转轴6旋转，其中，此处的上盖还特别包括磁体组件，旋转轴6通过磁体组件与输出轴11形成可拆卸的磁吸连接并能够跟随输出轴11旋转。
这种磁吸连接不同于输出轴11与旋转轴6之间常规的固定连接方式，磁吸连接易于拆除，直接手动外拉即可取出旋转轴6，安装时同样如此，将旋转轴6靠近输出轴11，磁体组件之间形成磁吸力即可。取出的旋转轴6可进行独立清洗，极为方便。
其中，这种磁吸连接时需要根据具体工况，例如搅拌器组件工作时的最大力矩等，来计算所需的磁吸力的大小，从而旋转磁体或调节输出轴11与旋转轴6之间的间距等。
在图1中，作为示例，上述的磁体组件可包括结构相同的上磁铁组件2和下磁铁组件3，上磁铁组件2和下磁铁组件3分别包括沿圆周方向依次间隔排列的偶数个磁铁(如图2、图3所示的四个)，在上磁铁组件2的底面和下磁铁组件3的顶面上，偶数个磁铁的磁极沿圆周方向依次错开，例如沿周向的磁极以N-S-N-S-N-S等形态分布，如图2、图3所示。由于上下磁铁组件的强力磁铁的个数相同且磁极分布相同，旋转电机1带动输出轴11旋转时，将产生耦合旋转磁场，带动旋转轴6转动，从而驱动搅拌器组件底端的旋转叶片7旋转，实现搅拌功能。在安装时，可手持搅拌器组件，使之靠近旋转电机1，上磁铁组件2和下磁铁组件3相互吸合，在拆卸时，直接拿走搅拌器组件即可。
具体地，为了将上磁铁组件2固定至输出轴11以跟随其旋转，图1所示的上磁铁组件2还包括磁铁托盘21，磁铁托盘21固定套装于旋转电机1的输出轴11上以跟随旋转，磁铁托盘21上设有沿圆周方向依次间隔排列的多个磁铁腔，上磁铁组件2的上磁铁22嵌装于磁铁腔中并通过盖板23封盖。磁铁腔的形状与上磁铁22形状、尺寸大致相同，上磁铁22可牢靠的镶嵌于磁铁腔中。盖板23封盖上磁铁22，可进一步防止上磁铁22在旋转时向上甩出。当然，此处仅为举例，上磁铁组件2的组成结构及安装结构也不限于此，例如在输出轴11的尺寸够大，强磁性的上磁铁22的尺寸够小的情况下，上磁铁22也可直接镶嵌在输出轴11中。
同样地，下磁铁组件3也可类似于上磁铁组件2，通过磁铁托盘或托架的形式固定套装于旋转轴6的顶端部61。但在图1所示的实施方式中，旋转轴6的顶端部61径向凸出，相较于旋转轴6的其余杆部的直径大，使得顶端部61具有足够尺寸容纳磁铁镶嵌其中。因此，下磁铁组件3的偶数个下磁铁31设置于搅拌器组件的旋转轴6的顶端部61，例如可固定嵌装于顶端部61的顶面凹槽内。
此外，为保持对旋转轴6的旋转定位，搅拌器组件还可包括轴承5，旋转轴6的顶端部61套设在轴承5内，轴承5可固定设置，其内的顶端部61能够相对于该轴承5自旋转。通过设置轴承5，可确保旋转轴6旋转时不产生偏斜或摆动。其中，轴承5可以为不生锈且环保的陶瓷轴承，其适于在食品加工装置中使用。
在本实施方式的带搅拌功能的上盖中，盖体总成包括内盖200和罩盖在该内盖200上方的外壳部100。图1中的外壳部100为用于安装电连接部分的把手壳体。旋转电机1和上磁铁组件2可设置在外壳部100与内盖200之间的 空腔内。同时，内盖200的中心部位可设有贯通孔，贯通孔上密封安装轴承座4，轴承座4的上卡槽设置为磁铁托盘卡槽，用于安放上磁铁组件2，轴承座4的底面可形成有向下开口的轴承卡槽41，上磁铁组件2和下磁铁组件3彼此磁吸连接时，被向上吸附的轴承5则至少部分地向上嵌入至轴承卡槽41中，实现对轴承5的限位，尤其是图1中的顶端部61下方还设有外径更大的凸缘，该凸缘将轴承5顶入轴承卡槽41中并轴向定位。这样，轴承5相对于轴承座4和内盖200的位置完全固定。
特别地，旋转轴6的顶端部61向上卡入轴承卡槽41中时，顶端部61的顶端面与轴承卡槽41的槽面之间形成有竖向间隔的安装间隙J。这样，在旋转轴6跟随输出轴11旋转时，顶端部61的顶端面不会与轴承座4产生任何旋转摩擦，减少旋转摩擦阻力。
在上述的带搅拌功能的上盖中，通过旋转轴6与输出轴11之间便于拆装的磁吸连接，使得前者既能够跟随后者旋转运动，又能够在需要时使二者结合或拆分，方便零部件保存、维护和运输，也易于组装操作，拆分后的搅拌器组件更便于清洗。
在此基础上，图1所示的包括锅具300的电动烹饪器具采用了上述带搅拌功能的上盖，上盖的搅拌器组件伸入锅具300内以翻搅加工食物。这种电动烹饪器具可以是自动烹饪机，例如IH加热(或热管加热)的炒菜机等。当然，上述带搅拌功能的上盖也不限于应用在炒菜机等自动烹饪机中，可以拓展应用于需要搅拌功能的上盖的任何其它电器中，例如搅拌机或豆浆机中等。
在图1中，IH加热的炒菜机包括IH加热盘400和设置在锅具300外周围的机壳500，IH加热盘400设置在锅具300的底部以对锅具300电磁加热。其中，锅具300的材质可以为弱导磁性的材料，能应用在电磁加热场合。因 此，锅具300可以为不锈钢锅具，例如304不锈钢等。同样地，搅拌器组件和磁体组件等可以为电磁不加热材料，从而在IH加热盘400工作时不对搅拌器组件和磁体组件等部件进行加热。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，例如上磁铁组件2和下磁铁组件3中各自的磁铁个数不限于图2、图3所示的四个，也可以是更多的六个、八个等等，也不限于图示的圆形磁铁，磁体也可以是永磁铁或电磁铁等，诸如此类改动均应包含在本发明的保护范围之内。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
