下面详细描述本申请的实施例，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，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图13描述根据本申请实施例的烹饪器具100。
如图1-图4所示，根据本申请一些实施例的烹饪器具100包括烹饪主体10、盖体组件20和加热装置15。
烹饪主体10包括烹饪容器11，盖体组件20设于烹饪主体10，盖体组件20用于开闭烹饪容器11，从而使烹饪容器11与盖体组件20之间限定出烹饪腔，其中，盖体组件20可以可拆卸地设于烹饪主体10，也可以可枢转地设于烹饪主体10，盖体组件20的朝向烹饪主体10的一侧设有第一风扇21，第一风扇21相对于盖体组件20可转动。
加热装置15用于对烹饪容器11内的食物进行加热，加热装置15可以设在烹饪主体10，例如加热装置15可以设在烹饪容器11的下方，从而直接对烹饪容器11的底部进行加热。当然，加热装置15也可以设在其他位置，例如加热装置15也可以设置在盖体组件20上。此外，加热装置还可以包括多个，分别设置在烹饪容器11和盖体组件20上。
进一步地，烹饪器具100还包括空炸头30和第一风扇21，空炸头30可分离地设于盖体组件20，第一风扇21设置在盖体组件20或空炸头30上，空炸头30包括电机32，电机32用于驱动第一风扇21转动。其中，烹饪器具100包括第一烹饪模式和第二烹饪模式，通过加热装置15的加热和第一风扇21的转动产生热空气，从而在烹饪腔中形成对流加热烹饪的第一烹饪模式，通过加热装置15加热烹饪容器11形成第二烹饪模式。
根据本申请实施例的烹饪器具100，通过将空炸头30可分离地设于盖体组件20，可以在第一烹饪模式下，通过烹饪主体10、盖体组件20以及空炸头30的配合，并采用电机32驱动第一风扇21转动实现对流加热烹饪，也可以在第二烹饪模式下，控制空炸头30的电机32不工作，或者将空炸头30拆离，通过烹饪主体10和盖体组件20的配合实现烹饪，两种烹饪模式可以一体烹饪，不需要将盖体组件20和空炸头30来回切换，操作简单，使用体验更好。
根据本申请的一些实施例，空炸头30设于盖体组件20的背向烹饪主体10的一侧。具体地，如图2所示，空炸头30设于盖体组件20的外顶部，即空炸头30与第一风扇21被盖体组件20隔开，从而方便清洗各部件。
烹饪器具100可以在第一烹饪模式下，通过烹饪主体10、盖体组件20以及空炸头30的配合，电机32在不与第一风扇21直接连接的状态下仍可以驱动第一风扇21转动实现烹饪。烹饪器具100也可以在第二烹饪模式下，控制空炸头30不工作，通过烹饪主体10和盖体组件20的配合实现烹饪，两种烹饪模式可以一体烹饪，不需要将盖体组件20和空炸头30来回切换，操作简单，使用体验更好。
在一些实施例中，电机32设有随其转子同步转动的第一磁铁322，第一风扇21设有第二磁铁212，第一磁铁322适于与第二磁铁212吸合，从而在电机32工作时带动第一风扇21转动。也就是说，在本实施例中，利用磁驱原理，并且采用外置空炸头30上的电机32可分离地驱动第一风扇21转动，使用第一风扇21驱动内部热场循环，实现 烘烤循环烹饪效果。
在一些实施例中，空炸头30具有进风口311和出风口312，进风口311和出风口312的其中一个位于空炸头30的顶面，另一个位于空炸头30的侧面。
在一些具体实施例中，空炸头30还包括壳体31和第二风扇34，进风口311和出风口312设于壳体31，第二风扇34设于壳体31内，电机32与第二风扇34相连，从而驱动第二风扇34转动，外界空气在第二风扇34的作用下从进风口311进入壳体31内，然后从出风口312排出，在此过程中，从出风口312排出的空气带走电机32周围的热量，从而对电机32进行散热，提高电机32的使用寿命。
如图3和图4所示，根据本申请的一些实施例，盖体组件20的朝向烹饪主体10的一侧设有安装轴22，第一风扇21可转动地安装于安装轴22。
为了减少第一风扇21相对于安装轴22的窜动量，在安装轴22上安装轴承28，使得第一风扇21通过轴承28可旋转地设于安装轴22。
具体地，安装轴22沿盖体组件20的厚度方向延伸，如图3所示，在盖体组件20处于关闭烹饪容器11的状态下，安装轴22沿上下方向延伸，并且安装轴22的上端与盖体组件20相连，轴承28套设于安装轴22且一侧止抵安装轴22的轴肩，第一风扇21的下侧设有限位凸环，并且第一风扇21的上侧设有卡接件，轴承28配合在限位凸环与卡接件之间，从而保证第一风扇21的定位安装。通过设置安装轴22，不仅可以保证第一风扇21的定位安装，而且可以保证对中效果，防止第一风扇21发生抖动。
如图4所示，在一些实施例中，安装轴22上设有限位件221，以对轴承28进行轴向限位，从而对第一风扇21进行轴向限位，确保第一风扇21的安装可靠性，保证第一风扇21可以正常工作。
在一些实施例中，安装轴22与盖体组件20可拆卸地相连。具体地，安装轴22可以与盖体组件20插装配合，也可以与盖体组件20通过磁吸结构吸合，还可以与盖体组件20通过连接件实现可拆卸地连接，或者与盖体之间20通过螺纹结构实现螺纹连接，从而在不需要空炸头30工作的烹饪模式下，将第一风扇21从盖体组件20拆卸下来，便于储存和清洗。
根据本申请的一些实施例，空炸头30与盖体组件20可拆卸地相连。
举例而言，需要烹饪器具100以第一烹饪模式工作时，将盖体组件20盖合在烹饪主体10上，将空炸头30设置在盖体组件20的顶部，并且将第一风扇21设在盖体组件20的下方，需要烹饪器具100以第二烹饪模式工作时，将盖体组件20盖合在烹饪主体10上，可以将空炸头30以及第一风扇21、安装轴22等拆卸下来，当然上述结构也可以不进行拆卸，装拆方便。
如图3和图4所示，根据本申请的一些实施例，盖体组件20包括金属盖29，金属盖29设置在电机32和第一风扇21之间，金属盖29设有与烹饪容器11扣合的盖牙，从而保证金属盖29与烹饪容器11之间的连接可靠性和密封性。
根据本申请的一些实施例，空炸头30和盖体组件20中的一个具有定位凹部27，空 炸头30和盖体组件20中的另一个具有定位凸部33，定位凸部33与定位凹部27配合。
具体地，如图7所示，空炸头30的底部设有朝下凸出设置的定位凸部33，盖体组件20的顶部设有向下凹陷设置的定位凹部27，空炸头30通过定位凸部33配合在定位凹部27内，实现空炸头30在盖体组件20上的定位安装，防止烹饪器具100在工作时，空炸头30相对于盖体组件20发生晃动或者脱离盖体组件20，确保烹饪器具100可以正常工作。
由此，通过采用定位凸部33与定位凹部27相配合的结构，可以实现空炸头30在盖体组件20上的定位安装，保证空炸头30在盖体组件20上的安装稳定性和可靠性，从而确保空炸头30可以正常工作。
在一些实施例中，烹饪容器11还包括空炸容器12，空炸容器12可分离地置于烹饪容器11内。
在一些示例中，空炸容器12具有过气孔121，在空炸容器12置于烹饪容器11内的状态下，空炸容器12与烹饪容器11之间限定出风道，风道通过过气孔121与空炸容器12的内腔连通。
由此，通过设置过气孔121，便于更好地对空炸容器12的内腔内的食材进行烹饪。例如，在空炸烹饪模式下，利用空炸容器12炸制其内腔中的食材时，设置过气孔121可以便于热风在风道与空炸容器12的内腔之间进行流动，提高对空炸容器12内食材的炸制烹饪效果。
在一些具体示例中，过气孔121设于空炸容器12的底壁，使得风道中的热风可以从底部进入空炸容器12内，然后空炸容器12内的热风在第一风扇21的作用下向上流动，再次流入风道中，如此往复循环。
根据本申请的一些实施例，第一烹饪模式为热空气对流加热模式，第二烹饪模式为传导加热模式，在烹饪器具100处于第一烹饪模式下，盖体组件20盖合于烹饪主体10，并且空炸头30设于盖体组件20，加热装置15的加热和第一风扇21的转动产生热空气对烹饪腔的食物进行热空气对流加热；在烹饪器具100处于第二烹饪模式下，盖体组件20盖合于烹饪主体10，并且允许空炸头30与盖体组件20分离，加热装置15对烹饪腔内的食物进行传导加热。
也就是说，在烹饪器具100处于热空气对流加热模式下，盖体组件20盖合于烹饪主体10，并且空炸头30设于盖体组件20，加热装置15对烹饪容器11进行加热，电机32驱动第一风扇21转动。在烹饪器具100处于传导加热模式下，盖体组件20盖合于烹饪主体10，并且允许空炸头30与盖体组件20分离以及允许空炸容器12与烹饪容器11分离，当然，空炸头30也可以不与盖体组件20分离，在此烹饪模式下，加热装置15对烹饪容器11进行加热，且控制空炸头30不工作。
在一些示例中，第一烹饪模式为空炸烹饪模式，第二烹饪模式为蒸煮烹饪模式，例如压力烹饪模式。
如图1-图5以及图12-图13所示，根据本申请另一些实施例的烹饪器具100包括烹 饪腔、第一风扇21和加热装置15，第一风扇21朝烹饪腔送风，加热装置15用于加热烹饪腔内的食物。
进一步地，烹饪器具100还包括空炸容器12和导风罩13，空炸容器12用于容纳食物，空炸容器12设置在烹饪腔内，烹饪腔的侧壁与空炸容器12之间限定出风道，空炸容器12的下部具有过气孔121，风道通过过气孔121与空炸容器12的内腔连通。
导风罩13盖设于空炸容器12上方，导风罩13具有通风口131，导风罩13用于将第一风扇21吹出的风引导至导风，例如可以将第一风扇21转动及加热装置15加热所产生的热空气引导至风道，并从过气孔121进入空炸容器12内部，从而用于烘烤食物。
根据本申请实施例的烹饪器具100，通过在空炸容器12的上方设置导风罩13，方便在第一风扇21的作用下形成的气流能够直接向下流入烹饪腔与空炸容器12之间形成的风道中，防止气流从空炸容器12的顶部进入空炸容器12中，保证风道与空气容器12之间的气流形成循环。
根据本申请的一些实施例，空炸容器12朝向第一风扇21的一面具有开口，导风罩13盖设在空炸容器12的开口上，通过在空炸容器12上设置开口，便于取放食材，通过将导风罩13盖设在空炸容器12的开口上，可以避免第一风扇21产生的风直接通过开口进入空炸容器12内。
如图3和图4以及图12和图13所示，根据本申请的一些实施例，导风罩13的中部具有通风口131，以使空炸容器12的内腔与烹饪腔连通，通风口131在垂直于第一风扇21转动轴线的平面内的正投影位于第一风扇21在转动时掠过的面积的范围之内，进一步防止气流从通风口131进入空炸容器12中，保证风道与空气容器12之间的气流形成循环。
根据本申请的一些实施例，第一风扇21位于空炸容器12中心轴的正上方，通风口131设置在导风罩13的中心处，通风口131的开口面积不大于第一风扇21在转动时掠过的面积，防止气流从通风口131进入空炸容器12中，保证风道与空气容器12之间的气流形成循环。
根据本申请的一些实施例，导风罩13的至少一部分外表面沿从导风罩13的中部到导风罩13的外边沿逐渐向下延伸，从而将在第一风扇21的作用下形成的气流能够直接向下流入烹饪腔与空炸容器12之间形成的风道中。
如图3和图4所示，在一些实施例中，导风罩13的上表面为倾斜面，倾斜面与水平面形成的夹角α为10°～60°例如，α可以为10°、30°、50°或者60°，从而更好地实现导流效果。当然，导风罩13的上表面也可以形成从导风罩13的中部到导风罩13的外边沿逐渐向下延伸的曲面(例如凸曲面)。
根据本申请的一些实施例，导风罩13与第一风扇21之间的最小间距为1-12mm，例如导风罩13与第一风扇21的最小间距可以为1mm、6mm、10mm、12mm，导风罩13与第一风扇21之间的间距不能太大，通过限定上述参数，可以确保第一风扇21吹出的绝大部分风引导至侧边的风道而不是从导风罩13的通风口131进入空炸容器12内。
如图3和图4所示，根据本申请的一些实施例，通风口131形成圆孔，通风口131的直径d与第一风扇21的最大直径D的比值为0～3/2。例如d/D可以为1/2、1或者3/2，使得第一风扇21形成的至少一部分气流可以避开通风口131，并沿着风道从空炸容器12的下部的过气孔121进入空炸容器12内。
如图3和图4所示，在一些实施例中，通风口131的半径r小于第一风扇21的扇叶的外缘与第一风扇21的中心在水平方向上的距离R1，通风口131的半径r大于第一风扇21的扇叶的内缘与第一风扇21的中心在水平方向上的距离R2。通过限定通风口131的半径r满足上述条件，使得第一风扇21形成的至少一部分气流可以避开通风口131，并沿着风道从空炸容器12的下部的过气孔121进入空炸容器12内。
如图13所示，根据本申请的一些实施例，空炸容器12的底壁内表面的中部设有凸部，至少一个过气孔121贯通凸部。通过在空炸容器12的底壁内表面设置凸部，并将至少一个过气孔121设在凸部上，可以避免在空炸容器12内放置大量食物的状态下将过气孔121堵死，同时对风进行引导，保证风道中的气流可以顺利从底部过气孔121进入空炸容器12内。
在一些实施例中，凸部形成沿至少一个过气孔121的周向延伸的翻边123或凸筋。利用翻边123或凸筋对至少一个过气孔121进行防护，从而阻挡空炸容器12内的食物进入该过气孔121而使该过气孔121发生堵塞。
在一些具体的实施例中，烹饪器具100在空炸烹饪模式下，电机32驱动第一风扇21转动，烹饪主体10的底部的加热装置15加热烹饪容器11，烹饪容器11通常为导热或电磁感应的金属材质，烹饪容器11受热后温度升高，第一风扇21吹出的气流在导风罩13的引导下，向下流入烹饪腔与空炸容器12之间形成的风道中，然后到达烹饪容器11的底部，与高温的烹饪容器换热后形成热空气，热空气经过空炸容器12中部的过气孔121上升进入到空炸容器12内部，热空气烹饪空炸容器12内部的食物，然后在风压作用下从导风罩13的通风口131中流出，从而完成热空气对食物的一次循环烘烤。
根据本申请进一步的实施例，烹饪器具100包括烹饪主体10和盖体组件20，烹饪主体10包括烹饪容器11，盖体组件20设于烹饪主体10，烹饪腔由烹饪容器11与盖体组件20限定出，加热装置15设置在烹饪主体10和盖体组件20中的至少一个上。
在一些实施例中，盖体组件20上设有第一风扇21，加热装置15位于烹饪容器11的底部，过气孔121位于空炸容器12的底壁的中部，空炸容器12的底壁面除过气孔121之外的其他壁面为封闭面。
由于加热装置15设置在烹饪容器11的底部，因此烹饪容器11的底部是加热的高温区，为了保证风道内的风与烹饪容器11的底部充分换热，在空炸容器12的底壁中部设置过气孔121，并将空炸容器12的底壁除去过气孔121之外的其他壁面设置为封闭面，当风经过烹饪容器11的底部和空炸容器12的底部之间的空间，可以与烹饪容器11的底部充分换热，从而形成热空气后再从过气孔121朝上流动进入空炸容器12内部烘烤食物。
与在空炸容器的底部整个面设置多个间隔布置的过气孔的相关技术相比，本实施例能避免风到达烹饪容器11的底部和空炸容器12的底部之间的空间后直接从空炸容器12侧边的小孔进入空炸容器12内部，而没有与烹饪容器11进行充分换热，导致侧边的食物和中部的食物熟的程度不均匀，保证食物烹饪的均匀性，从而提高烹饪效果。
根据本申请的一些实施例，空炸容器12具有过气孔121，在空炸容器12置于烹饪腔内的状态下，空炸容器12与烹饪腔之间限定出风道，风道通过过气孔121与空炸容器12的内腔连通。
由此，通过设置过气孔121，便于更好地对空炸容器12的内腔内的食材进行烹饪。例如，在空炸烹饪模式下，利用空炸容器12炸制其内腔中的食材时，设置过气孔121可以便于热风在风道与空炸容器12的内腔之间进行流动，提高对空炸容器12内食材的炸制烹饪效果。
在一些实施例中，烹饪器具100还包括支架14，支架14可分离地设于烹饪腔内，用于支撑空炸容器12，并将空炸容器12与烹饪腔分隔开。
这样不仅便于将空炸容器12稳定地设置在烹饪腔内，提高空炸容器12的设置可靠性，而且便于在空炸容器12的外底壁与烹饪腔的内底壁之间限定出隔离间隙，以便于更好地对空炸容器12内的食材进行烹饪。例如，在空炸容器12置于烹饪腔内进行空炸烹饪时，隔离间隙可以辅助对烹饪腔内热风对流进行导向，加强烹饪腔内部热风的对流强度，改善空炸容器12内食材的烘烤炸制效果。
根据本申请进一步的实施例，烹饪器具100包括烹饪主体10和盖体组件20，烹饪主体10包括烹饪容器11，盖体组件20设于烹饪主体10，烹饪腔由烹饪容器11与盖体组件20限定出，加热装置15设置在烹饪主体10和盖体组件20中的至少一个上。盖体组件20上连接有空炸头30，空炸头30设于盖体组件20的背向烹饪主体10的一侧，空炸头30上设有用于驱动第一风扇21转动的电机32。
由此，通过在盖体组件20上设置空炸头30，并将电机32设置在空炸头30上，可以在一种烹饪模式下，通过烹饪主体10、盖体组件20以及空炸头30的配合，采用电机32驱动第一风扇21转动实现烘烤循环烹饪效果，也可以在另一种烹饪模式下，控制电机32不工作，通过烹饪主体10和盖体组件20的配合实现烹饪，两种烹饪模式可以一体烹饪，不需要将盖体组件20和空炸头30来回切换，操作简单，使用体验更好。
在一些实施例中，电机32设有随其转子同步转动的第一磁铁322，第一风扇21设有第二磁铁212，第一磁铁322适于与第二磁铁212吸合，以在电机32工作时带动第一风扇21转动。通过设置第一磁铁322和第二磁铁212，无需对盖体组件20进行开孔以使电机32与第一风扇21直接连接，利用磁驱原理，即可实现电机32对第一风扇21的驱动，既保证了盖体组件20的结构完整性和结构强度，又减少了对盖体组件20的加工工序。
在一些示例中，第一风扇21包括内圈和扇叶，扇叶的一端与内圈连接且另一端朝外延伸，第二磁铁212设置在内圈内，内圈的中部具有装配孔，通风口131的开口面积不 小于内圈的面积，保证第一风扇21形成的至少一部分气流可以避开通风口131，顺利从底部过气孔121进入空炸容器12内。
在一些实施例中，烹饪器具1000包括烘烤烹饪模式和蒸煮烹饪模式，在烘烤烹饪模式下，盖体组20盖合于烹饪主体10，并且空炸头30设于盖体组件20，加热装置15加热以及电机32驱动第一风扇21转动以产生热空气，在蒸煮烹饪模式下，盖体组件20盖合于烹饪主体10，并且允许空炸头30与盖体组件20分离，加热装置15对烹饪腔内的食物进行加热。其中，蒸煮烹饪模式包括水蒸气蒸烹饪、煮饭烹饪、炖烹饪和压力烹饪等。
由此，本实施例的烹饪器具100可以在烘烤烹饪模式下，通过烹饪主体10、盖体组件20以及空炸头30的配合，并采用电机32驱动第一风扇21转动实现烹饪，也可以在蒸煮烹饪模式下，控制空炸头30上的电机32不工作，通过烹饪主体10和盖体组件20的配合实现烹饪，两种烹饪模式可以一体烹饪，不需要将盖体组件20和空炸头30来回切换，操作简单，使用体验更好。
如图1-图4所示，根据本申请又一些实施例的烹饪器具100包括烹饪主体10、盖体组件20、风机组件和加热装置15。
盖体组件20能与烹饪主体10盖合和分离，盖体组件20盖合在烹饪主体10上时，盖体组件20与烹饪主体10之间限定出烹饪腔，风机组件包括第一风扇21和电机32，电机32用于驱动第一风扇21转动，风机组件设置在盖体组件20或烹饪主体10上，加热装置15设于烹饪主体10或盖体组件20，用于加热烹饪腔内的食物。
其中，电机32设有磁性件，第一风扇为磁性风扇，电机32工作时通过磁性件带动磁性风扇转动。
根据本申请实施例的烹饪器具100，通过在电机32上设置磁性件来驱动磁性风扇，无需对盖体组件20或者烹饪主体10进行开孔以使电机32与第一风扇21直接连接，利用磁驱原理，即可实现电机32对第一风扇21的驱动，既保证了盖体组件20或烹饪主体10的结构完整性和结构强度，又减少了对盖体组件20或烹饪主体10的加工工序。
根据本申请的一些实施例，烹饪器具100包括烘烤烹饪模式和蒸煮烹饪模式，盖体组件20盖合在烹饪主体10上，在烘烤烹饪模式下，加热装置15加热以及电机32驱动第一风扇21转动以产生热空气，在蒸煮烹饪模式下，烹饪腔内形成密封空间。
由此，通过在盖体组件20上设置第一风扇21和电机32，可以在烘烤烹饪模式下，采用电机32驱动第一风扇21转动、以及采用加热装置15对烹饪腔加热以实现烹饪，也可以在蒸煮烹饪模式下，采用加热装置15对烹饪腔加热以实现烹饪，两种烹饪模式可以，操作简单，使用体验更好。
也就是说，本实施例的烹饪器具100既能进行烘烤烹饪又能进行蒸煮烹饪，由于蒸煮烹饪通常要对烹饪腔进行密封，通过采用电机32的磁性件驱动第一风扇21避免了在盖体组件20上开孔用于穿电机轴，保证了烹饪腔在蒸煮模式下的密封性，尤其是蒸煮模式是高压烹饪式，密封性好尤其重要。
根据本申请的一些实施例，磁性件为第一磁铁322，磁性风扇包括第二磁铁212，第一磁铁322适于与第二磁铁212吸合，从而在电机32工作时带动第一风扇21转动。也就是说，第一磁铁322与第二磁铁212相互吸合，从而使第二磁铁212可以与第一磁铁322同步运动，进而实现电机32驱动第一风扇21转动。
由此，通过设置第一磁铁322和第二磁铁212，无需对盖体组件20进行开孔以使电机32与第一风扇21直接连接，利用磁驱原理，即可实现电机32对第一风扇21的驱动，既保证了盖体组件20的结构完整性和结构强度，又减少了对盖体组件20的加工工序。
此外，通过设置第一磁铁322和第二磁铁212，无需对盖体组件20进行开孔以使电机32与第一风扇21直接连接，利用磁驱原理，即可实现电机32对第一风扇21的驱动，既减少了对盖体组件20的加工工序，又保证了盖体组件20的结构完整性和结构强度，不影响蒸煮烹饪模式下烹饪腔的密封性能，尤其是当蒸煮烹饪模式为高压烹饪模式时，其密封要求高且密封难度大，若在盖体组件上开孔用于电机轴穿过，势必会影响高压烹饪时盖体组件20的密封性，本实施例无需对盖体组件20进行开孔，更好地保证了盖体组件20的密封性能。
在一些实施例中，第一磁铁322和第二磁铁212的位置正对，第一磁铁322和第二磁铁212的数量相等且位置一一对应，第一磁铁322和第二磁铁212的异极相对。
例如，第一磁铁322和第二磁铁212的数量均为一个，并且第一磁铁322与第二磁铁212相互吸合，使得电机32与第一风扇21在不直接相连的状态下，电机32在工作时，仍然可以驱动第一风扇21转动，简化了盖体组件20的结构。
再如，第一磁铁322和第二磁铁212的数量可以分别为多个，并且多个第一磁铁322和多个第二磁铁212位置一一对应地吸合，从而进一步地确保电机32可以正常驱动第一风扇21转动。
在一些可选的实施例中，第一磁铁322和第二磁铁212的数量分别为2-4个，例如，第一磁铁322和第二磁铁212的数量可以分别为两个或三个，所有的第一磁铁322的两极布置方向相同。
在一些示例中，第一磁铁322和第二磁铁212的S极均朝上且N极均朝下，从而使第一磁铁322的N极与第二磁铁的S极正对且可以相互吸合；在另一些示例中，第一磁铁322和第二磁铁212的N极均朝上且S极均朝下，从而使第一磁铁322的S极与第二磁铁的N极正对且可以相互吸合，保证电机32在与第一风扇21不直接连接的状态下仍可以驱动第一风扇21转动。
如图7-图11所示，在另一些可选的实施例中，第一磁铁322和第二磁铁212的数量分别多于三个，例如，第一磁铁322和第二磁铁212的数量可以分别为四个或者四个以上，所有的第一磁铁322沿一圆周方向间隔布置，对应地，所有的第二磁铁212沿一圆周方向间隔布置，至少两个相邻布置的第一磁铁322的两极布置方向相反。
具体地，其中一个第一磁铁322的S极朝上且N极朝下，与上述第一磁铁322相邻的两个第一磁铁322的N极朝上且S极朝下；对应地，与其位置对应的第二磁铁212 的S极朝上且N极朝下，与上述第二磁铁212相邻的两个第二磁铁212的N极朝上且S极朝下。
如图7所示，根据本申请的一些实施例，电机32与第一磁铁322之间设有隔磁件35。通过在电机32与第一磁铁322之间设置隔磁件35，可以防止第一磁铁322的磁极影响电机32的转动及使用寿命。
为了保证第一磁铁322在电机32上的定位安装，从而保证第一磁铁322可以与电机32的转子同步转动，在实施例中，电机32的转子的端面具有第一安装凹部321，第一磁铁322设于第一安装凹部321。
类似地，为了保证第二磁铁212在第一风扇21上的安装可靠性，从而保证第二磁铁212可以与第一风扇21同步转动，在本实施例中，第一风扇21的轮毂的朝向电机32的一面具有第二安装凹部211，第二磁铁212设于第二安装凹部211。
如图4所示，根据本申请的一些实施例，盖体组件20的朝向烹饪主体10的一侧设有安装轴22，安装轴22与盖体组件20插接装配或者焊接，第一风扇21可转动地设于安装轴22。通过设置安装轴22，方便第一风扇21的安装。
在一些实施例中，安装轴22和第一风扇21之间安装有轴承28，第一风扇21通过轴承28可转动地安装于安装轴22，保证第一风扇21的转动稳定性。
在一些实施例中，安装轴22上设有紧固件25、位于紧固件25与第一风扇21之间的防护罩23，紧固件25对防护罩23进行轴向限位。
由此，通过设置防护罩23，不仅可以对第一风扇21形成防护，而且可以防止用户误碰到第一风扇21的叶片而划伤手指；通过在安装轴22上设置紧固件25，可以对防护罩23进行限位和固定，并且当需要拆下防护罩23进行清洗时，将紧固件25拆下即可拆卸防护罩23，操作简单、易于实现。
在一些示例中，安装轴22上还设有限位件221和垫片24，限位件221靠近轴承28设置，垫片24靠近紧固件25设置，防护罩23位于限位件221和垫片24之间。通过在安装轴22上设置限位件221，可以对轴承28进行轴向限位，通过设置垫片24，可以对防护罩23以及紧固件25形成保护，防止零件表面发生磨损。
根据本申请进一步的实施例，风机组件设置在盖体组件20上，盖体组件20上连接有空炸头30，空炸头30设于盖体组件20的背向烹饪主体10的一侧，电机32设置在空炸头30内。
由此，通过在盖体组件20上设置空炸头30，并将电机32设置在空炸头30内，可以在烘烤烹饪模式下，通过烹饪主体10、盖体组件20以及空炸头30的配合，并利用磁驱原理，采用电机32驱动第一风扇21转动实现烘烤循环烹饪效果，也可以在蒸煮烹饪模式下，控制电机32不工作，通过烹饪主体10和盖体组件20的配合实现烹饪，两种烹饪模式可以一体烹饪，不需要将盖体组件20和空炸头30来回切换，操作简单，使用体验更好。
在一些实施例中，空炸头30和盖体组件20中的一个具有定位凹部27，空炸头30 和盖体组件20中的另一个具有定位凸部33，定位凸部33与定位凹部27配合。
具体地，如图7所示，空炸头30的底部设有朝下凸出设置的定位凸部33，盖体组件20的顶部设有向下凹陷设置的定位凹部27，空炸头30通过定位凸部33配合在定位凹部27内，实现空炸头30在盖体组件20上的定位安装，防止烹饪器具100在工作时，空炸头30相对于盖体组件20发生晃动或者脱离盖体组件20，确保烹饪器具100可以正常工作。
由此，通过采用定位凸部33与定位凹部27相配合的结构，可以实现空炸头30在盖体组件20上的定位安装，保证空炸头30在盖体组件20上的安装稳定性和可靠性，从而确保空炸头30可以正常工作。
如图7和图8所示，在一些示例中，定位凸部33和定位凹部27中的一个侧壁具有导向筋331，定位凸部33和定位凹部27中的另一个具有导向槽(图中未示出)，导向槽与导向筋331配合。
由此，通过采用导向筋331与导向槽相配合的结构，可以确保空炸头30内的电机32的中心轴线与盖体组件20上的第一风扇21的中心轴线重合，从而保证电机32可以正常驱动第一风扇21转动。
需要说明的是，为了进一步保证空炸头30的稳定性，可以采用多个导向筋331与多个导向槽一一对应相配合的结构。具体地，如图6和图7所示，定位凸部33的侧壁设有多个沿其周向间隔布置的导向筋331，每个导向筋331沿上下方向延伸，定位凹部27的侧壁设有多个导向槽。
如图3和图4所示，在一些示例中，盖体组件20包括金属盖29，金属盖29上设有与烹饪主体10扣合的盖牙，从而保证金属盖29与烹饪主体10之间的连接可靠性和密封性。
其中，定位凹部27的底壁为金属盖29的一部分，电机32位于金属盖29的上方，第一风扇21位于金属盖29的下方，即金属盖29将电机32和第一风扇21隔开，无需对金属盖29进行开孔以使电机32与第一风扇21直接连接，利用磁驱原理，即可实现电机32对第一风扇21的驱动，既保证了金属盖29的结构完整性和结构强度，又减少了对金属盖29的加工工序。
在一些实施例中，烘烤烹饪模式为空炸烹饪模式，蒸煮烹饪模式为高压烹饪模式，在烹饪器具100处于空炸烹饪模式下，盖体组件20盖合于烹饪主体10且空炸头30设于盖体组件20；在烹饪器具处于高压烹饪模式下，盖体组件20盖合于烹饪主体10且允许空炸头30与盖体组件20分离。
也就是说，在烹饪器具100处于空炸烹饪模式下，盖体组件20盖合于烹饪主体10，并且空炸头30设于盖体组件20，加热装置15对烹饪腔进行加热，电机32驱动第一风扇21转动。在烹饪器具100处于高压烹饪模式下，盖体组件20盖合于烹饪主体10，并且允许空炸头30与盖体组件20分离，当然，空炸头30也可以不与盖体组件20分离，在此烹饪模式下，加热装置15对烹饪腔进行加热，且控制空炸头30内的电机32不工 作。
下面结合附图详细描述根据本申请的烹饪器具100的一个具体实施例。
根据本申请一个实施例的烹饪器具100包括烹饪主体10、盖体组件20和空炸头30。
其中，烹饪主体10包括外壳、烹饪容器11、空炸容器20、导风罩13、支架14和加热装置15。
在一些示例中，外壳可以形成一个整体件，烹饪容器11和加热装置15可以均设置在外壳内，烹饪容器11可分离地设于外壳内且位于加热装置15的上方，从而将烹饪容器11和加热装置15组合在一起并配合盖体组件20、空炸头30使用。
在另一些示例中，这里的外壳可以包括底座以及外罩，底座和外罩可分离设置，加热装置15设于底座以组合形成加热基座，烹饪容器11设于外罩内，从而使烹饪器具100形成在上下方向布置的三段式结构，具体地，从上至下依次为：盖体组件20(或者，盖体组件20和空炸头30组合结构A)、外罩与烹饪容器11等的组合结构B、底座与加热装置15等的组合结构C，三部分组合结构可分离设置。
其中，支架14可分离地设于烹饪容器11内的底部，空炸容器20支撑在支架14上，从而使空炸容器20的外壁面与烹饪容器11的内壁面之间隔开以形成风道，导风罩13设于空炸容器20的顶部且具有通风口131，空炸容器12的底壁具有过气孔121，空炸容器12的内腔通过通风口131、过气孔121与风道连通。其中，空炸容器12的侧壁上部设有两个相对布置的提手122，方便用户取放空炸容器12。
盖体组件20可分离地设于烹饪主体10的顶部，盖体组件20的朝向烹饪主体10的一侧设于第一风扇21、安装轴22、限位件221、防护罩23、垫片24、紧固件25和轴承28，安装轴22的上端与盖体组件20相连，第一风扇21通过轴承28可旋转地设于安装轴22上，限位件221止抵在轴承28的下侧以对轴承28进行轴向限位，防护罩23和垫片24设于安装轴22上，并且防护罩23位于限位件221与垫片24之间，这样第一风扇21通过轴承28随着安装轴22的转动而转动，而防护罩23、限位件221与垫片24则不动，紧固件25固定在安装轴22的下端，紧固件25用于固定防护罩23，紧固件25可供用户拆下，拆下紧固件25可将防护罩23拆下清洗。其中，第一风扇21的朝向盖体组件20的一侧设有多个第二安装凹部211，每个第二安装凹部211内设有第二磁铁212。
空炸头30可拆卸地设于盖体组件20的背向烹饪主体20的一侧，空炸头30包括壳体31和电机32，壳体31包括底壳3101以及设于底壳3101上的上盖3102，底壳3101与上盖3102之间限定出容纳空间，电机32设于容纳空间内，电机32上设有多个第一安装凹部321，每个第一安装凹部321内设有与转子同步转动的第一磁铁322。
进一步地，上盖3102设有进风口311，底壳3101的侧壁设有出风口312，容纳空间内还设于与电机32相连的第二风扇34，第二风扇34在转动时驱动外界空气从进风口311进入容纳空间中，然后再从出风口312排出，在此过程中带走电机32周围的热量，达到散热效果。
用户需要烹饪器具100以压力烹饪模式或者蒸煮烹饪模式工作时，可以将空炸头30 以及安装轴22等结构从盖体组件20上拆卸下来，也可以不将以上结构拆卸下，控制加热装置15工作且控制空炸头30不工作；用户需要烹饪器具100以空炸烹饪模式工作时，将空炸头30设在盖体组件20上，控制加热装置15以及空炸头30工作，从而使得电机32驱动第一风扇21转动，实现烹饪容器11内部热场循环。
