由第二驱动电机带动第二转轴转动，从而带动内锅发生转动。
10.本公开提供的饭煲，所述内锅还包括：扰流凸起，设于所述内锅的内壁上，所述扰流凸起向所述内锅的内部凸起。
扰流凸起能够增加内锅内壁的粗糙程度，从而提高内锅带动食材流动的能力。内锅在转动过程中，内锅内的液体会产生漩涡。根据边界层理论，流体会紧贴内锅表面流动。当内锅表面有凸起时，流体会在筋条的最高位发生剥离，向垂直方向冲去，在内锅上，表现为向内锅中心冲去。并且因为筋条之后的空间，流体速度减慢，根据伯努利定理，该处压力增加，从而使该处产生涡。如此根据以上两点，内锅表面增加凸起，在内锅运动时，会增加对流体的扰动，使更多的流体向内锅中心处扩散。
11.本公开提供的饭煲，所述扰流凸起设于所述内锅内部远离所述锅盖的一侧。
保证扰流凸起能够更大程度的与内锅内部的食材接触。
12.本公开提供的饭煲，所述扰流凸起为圆弧形，且所述扰流凸起沿所述内锅的内壁延伸。
提高扰流凸起的扰动面积。
13.本公开提供的饭煲，所述扰流凸起有三个，相邻所述扰流凸起之间的夹角为120°。
扰流凸起是为了搅动食材，使食材均匀受热。因此，三个呈120°角设置的扰流凸起，能够具有更好的搅动食材受热的效果。
14.本公开提供的饭煲，所述扰流凸起一端远离所述锅盖设置，另一端延伸的高度h不低于所述加热组件的高度H。
由于加热组件起到加热作用，因此内锅靠近加热组件部分的温度相对较高，因此，扰流凸起针对靠近加热组件的部位设置能够起到充分搅动，提高食材温度分布的均匀性的作用。由于内锅工作过程中会发生转动，因此h的值大于H的值时，在转动过程中，也能更大程度的针对加热组件附近的食材流动。

此外，下面所描述的本公开不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
实施例1
本实施例提供一种饭煲，如图1、图2所示，包括：内锅1和支架2，所述支架2上设有加热组件；中间架3，所述内锅1设于所述中间架3上，所述中间架3活动连接在所述支架2上；驱动机构，被设置为带动所述内锅1和/或所述中间架3相对于所述支架2发生运动。内锅1工作时，能够在驱动机构的带动下相对于支架2发生运动。由于加热组件位于支架2上，因此能够在内锅1运动过程中，将内锅1的不同部位朝向加热组件，从而使得加热组件实际加热的面积增大，从而消除内锅1不同部位受热不均匀的问题。另一方面，由于内锅1相对于支架2发生运动，因此内锅1内部的食材也随内锅1发生运动，尤其是煲汤或者熬粥时，食材更易发生流动，使食材通过流动能够更均匀的与内锅1外壁进行换热。同时，根据内锅1的不同运动状态，能够在内锅1内部形成多股流动方向不同的食材，使食材在烹饪过程中不断发生撞击，从而提高换热效率，使食材受热更加均匀，不易发生温度分层的情况。
其中，对于内锅1的形状不做具体限制，本实施例中，如图1、图2所示，内锅1为球形。作为可替换的实施方式，内锅1可以为具有一定容纳空间的任意形状。
本实施例中，如图2、图4所示，所述支架2包括：第一回转支撑部22，所述中间架3回转支撑于所述第一回转支撑部22上；第一驱动电机23，所述第一驱动电机23的输出端连接所述中间架3。中间架3回转支撑于第一回转支撑部22上，使得中间架3在第一驱动电机23的带动下发生转动。而内锅1设于中间架3上，因此内锅1随中间架3共同转动。
对于第一回转支撑部22的数量不做具体限制，本实施例中，如图4所示，所述第一回转支撑部22有两个，两所述第一回转支撑部22对称设置于所述中间架3两侧。对称设于中间架3两侧的第一回转支撑部22能够更加平稳的支撑中间架3，保证内锅1运动时能够平稳进行。用户使用时，能够避免汤水外溅，提高用户体验。作为可替换的实施方式，第一回转支撑部22为一个。
其中，如图1、图3所示，所述中间架3包括：第一转轴32，一端指向所述内锅1，另一端向所述第一回转支撑部22延伸，所述第一回转支承部包括第一回转支撑槽，所述第一转轴32回转支撑于所述第一回转支撑槽内。第一回转支撑槽能够提高与第一转轴32的接触面积，提高第一转轴32转动的平稳性。
本实施例中，如图3所示，所述中间架3还包括：限位部31，所述第一转轴32设于所述限位部31上；第二回转支撑部33，设于所述限位部31上，所述内锅1朝向所述限位部31伸出由第二转轴11，所述第二转轴11回转支撑于所述第二回转支撑部33内。第二转轴11位于限位部31上，因此在中间架3能够带动内锅1以第一转轴32为中心转动时，内锅1还能够相对于中间架3，以第二转轴11为中心发生转动。本方案增加了内锅1的转动范围，提高了内锅1的转动幅度，进一步提高了内锅1本身受热的均匀程度，还加剧了内锅1内部食材的运动，从而提升了食材受热的均匀程度。
其中，如图3所示，所述第一转轴32与所述第二转轴11的延长线相交得到所述内锅1的转动中心。第一转轴32与第二转轴11的延长线相交时，能够进一步提高内锅1的转动幅度，并且使得内锅1在转动过程中，与支架2上加热组件之间的距离不变。
对于加热组件的形式不做具体限制，本实施例中，如图2、图4所示，加热组件为加热盘21，加热盘21位于支架2上，正对内锅1的底部设置。本实施例中，内锅1为球形，加热盘21朝向内锅1底部的面为凹面211。加热盘21 内部为电磁线圈结构，使内锅1与加热盘21之间具有一定间隙的情况下，也能被充分加热。同时还避免了内锅1与加热盘21接触阻碍内锅1运动。
对于限位部31的形状不做具体限制，本实施例中，如图1、图3所示，，所述限位部31为环形，且限位部31的横截面为圆形。所述限位部31的内侧朝向所述内锅1设置，所述限位部31的外侧朝向所述第一回转支撑部22设置。环形的限位部31与球形的内锅1相互配合，能够使内锅1转动过程中与限位部31之间的距离基本不变，防止内锅1发生转动时与限位部31发生干涉。作为可替换的实施方式，限位部31为多边形或三角形。
其中，如图3所示，所述限位部31的圆心位于所述内锅1的转动中心上。防止内锅1转动过程中与限位部31之间的间隙发生变化而产生干涉。
本实施例中，如图1、图3所示，所述中间架3还包括：第二驱动电机34，设于所述限位部31上，所述第二驱动电机34的输出端连接所述第二转轴11。由第二驱动电机34带动第二转轴11转动，从而带动内锅1发生转动。
对于内锅1的结构不做具体限制，本实施例中，如图3、图4所示，所述内锅1还包括：扰流凸起12，设于所述内锅1的内壁上，所述扰流凸起12向所述内锅1的内部凸起。扰流凸起12能够增加内锅1内壁的粗糙程度，从而提高内锅1带动食材流动的能力。内锅1在转动过程中，内锅1内的液体会产生漩涡。根据边界层理论，流体会紧贴内锅1表面流动。当内锅1表面有凸起时，流体会在筋条的最高位发生剥离，向垂直方向冲去，在内锅1上，表现为向内锅1中心冲去。并且因为筋条之后的空间，流体速度减慢，根据伯努利定理，该处压力增加，从而使该处产生涡。如此根据以上两点，内锅1表面增加凸起，在内锅1运动时，会增加对流体的扰动，使更多的流体向内锅1中心处扩散。作为可替换的实施方式，内锅1内部去除扰流凸起12，使内锅1内部呈现相对光滑的内表面，也能够实现本实施例的目的。
对于扰流凸起12的设置位置不做具体限制，本实施例中，如图4所示，所述扰流凸起12设于所述内锅1内部远离所述锅盖13的一侧，保证扰流凸起12能够更大程度的与内锅1内部的食材接触。作为可替换的实施方式，扰流凸起12位于内锅1深度方向的中间部位。作为另一种可替换的实施方式，扰流凸起12靠近内锅1顶部的开口设置。
对于扰流凸起12的形状不做具体限制，本实施例中，如图4所示，所述扰流凸起12为圆弧形，且所述扰流凸起12沿所述内锅1的内壁延伸，以提高扰流凸起12的扰动面积。作为可替换的实施方式，扰流凸起12一端贴合内锅1的内壁，另一端沿着内锅1的内壁方向延伸，并逐渐脱离所述内锅1的内壁。
对于扰流凸起12的数量不做具体限制，本实施例中，如图3所示，所述扰流凸起12有三个，相邻所述扰流凸起12之间的夹角为120°。作为可替换的实施方式，扰流凸起12为一个、两个或者三个以上。
本实施例中，如图4所示，所述扰流凸起12一端远离所述锅盖设置，另一端延伸的高度h不低于所述加热组件的高度H。由于加热组件起到加热作用，本实施例中，如图4所示，加热组件为加热盘21。加热盘21产生的磁场分布在加热盘21凹陷的凹面211附近。因此内锅1靠近加热盘21部分的温度相对较高，因此，扰流凸起12针对靠近加热盘21的部位设置能够起到充分搅动，提高食材温度分布的均匀性的作用。由于内锅1工作过程中会发生转动，因此h的值大于H的值时，在转动过程中，也能更大程度的针对加热组件附近的食材流动。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本公开创造的保护范围之中。
