在侧吸模式下，导流板组件30位于进风口11中心位置的下方，第二拢烟腔12的内壁与导流板组件30的侧部形成油烟通道。倾斜设置的内壁，提升了拢烟的面积，提升了油烟机排出油烟的效率。
综上所述，本申请实施例提供的油烟机，包括机体10、运动组件20B和导流板组件30。机体10的底部构造有进风口11，厨房内的油烟沿进风口11排出室外。运动组件20B连接于机体10和导流板组件30，导流板组件30水平设置在进风口11的下方，运动组件20B可以改变导流板组件30相对于进风口11的位置，使导流板组件30在避让位置和遮挡位置之间切换。在避让位置下，导流板组件30避开进风口11的中心位置，进风口11沿着中心位置吸气，采用顶吸模式将油烟排出室外。在遮挡位置下，导流板组件30位于进风口11中心位置的下方，油烟从导流板组件30的侧部进入进风口11，采用侧吸模式将油烟排出室外。油烟机在运动组件20B和导流板组件30的共同作用下，可以在顶吸模式和侧吸模式之间切换，以适应不同的使用环境。
在进风口11处设置有第二拢烟腔12的情况下，油烟机的拢烟面积较大，效率较高，能够快速将厨房内的油烟排出。
高温油烟上升至第二拢烟腔12处时，受到第二拢烟腔12的内壁的阻挡，油烟不会向四周扩散，避免了油烟扩散至厨房内其他区域。
第二拢烟腔12形成喇叭状结构，倾斜设置的内壁降低了油烟侧吸时的阻力，有助于油烟顺利流动至进风口11处。
在导流板组件30包括第三导流板组件和第四导流板组件时，第三导流板组件和第四导流板组件对称设置。
第三导流板组件和第四导流板组件同时远离时，两者之间具有间距，可以避开进风口11的中心位置。

请参考图14-图17，导流板组件20包括第五导流板113和第六导流板116，油烟机100还包括：基座组件120。第五导流板113和第六导流板116部分地阻挡进风口11并沿同一平面设置。基座组件120设置在第五导流板113和第六导流板116相背的一侧，以向第五导流板113和第六导流板116提供用于转动的转轴。驱动组件130用于驱动第五导流板113和第六导流板116反向同角度转动，以使得第五导流板113和第六导流板116相近的一侧靠近进风口11移动。
具体地，在图示的实施方式中，第五导流板113沿左右方向呈对称设置。第五导流板113设置在进风口11的左侧，第六导流板116设置在进风口11的右侧，且均设置在进风口11朝向的位置。沿上下方向，进风口11在油烟机100上朝下设置，导流板组件20设置在进风口11的下方，且导流板组件20和进风口11之间会设置有一定的间距，从而使得导流板组件20对进风口11部分地阻挡，位于油烟机100下方的空气则能够从进风口11未被导流板组件20阻挡的区域进入进风口11。
可以理解，第五导流板113沿自身板状结构延伸的方向可形成有平面，第六导流板116沿自身板状结构延伸的方向也可形成有平面。第五导流板113和第六导流板116沿同一平面设置，指的是第五导流板113和第六导流板116分别形成的平面为同一平面，从而使得第五导流板113和第六导流板116位于同一平面。
由于第五导流板113和第六导流板116之间会具有相互靠近的部分和相互远离的部分，对于导流板组件20而言，第五导流板113和第六导流板116相近的一侧，指的是第五导流板113和第六导流板116相互靠近的部分，第五导流板113和第六导流板116相背的一侧，指的是第五导流板113和第六导流板116相互远离的部分。在图示的实施方式中，第五导流板113和第六导流板116相近的一侧包括第五导流板113的右侧和第六导流板116的左侧，第五导流板113和第六导流板116相背的一侧包括第五导流板113的左侧和第六导流板116的右侧。
在上述基础上，请结合图14，未被阻挡的区域主要分布于第五导流板113的左侧和第六导流板 116的右侧，使得油烟机100下方的空气主要从第五导流板113的左侧和第六导流板116的右侧进入进风口11。请再结合图16，基座组件120的其中一部分设置在第五导流板113的左侧，基座组件120的另外一部分设置在第六导流板116的右侧，使得基座组件120向第五导流板113提供的转轴位于第五导流板113的左侧，且基座组件120向第六导流板116提供的转轴位于第六导流板116的右侧。
在驱动组件130带动第五导流板113和第六导流板116活动的情况下，驱动组件130能够以相同的速度来驱动第五导流板113和第六导流板116，使得第五导流板113可以围绕位于第五导流板113左侧的转轴逆时针转动，第六导流板116可以围绕位于第六导流板116右侧的转轴顺时针转动，第五导流板113和第六导流板116以相同的转动速度反向转动，且第五导流板113的右侧会开始靠近进风口11移动，以及第六导流板116的左侧会开始靠近进风口11移动。
可以理解，第五导流板113和第六导流板116反向同角度转动，使得第五导流板113和第六导流板116能够进行同步转动。由于第五导流板113和第六导流板116的同步转动，第五导流板113左侧的区域内的空气沿进入进风口11的方向可具有更大的横截面，以及第六导流板116右侧的区域内的空气沿进入进风口11的方向也可具有更大的横截面，从而会增加空气进入进风口11的流量。而且，转动后的第五导流板113和第六导流板116相对于进风口11呈倾斜姿态而形成有角度，空气会沿第五导流板113和第六导流板116倾斜的表面进入进风口11，使得第五导流板113和第六导流板116对空气具有导向的效果，最终能够提高油烟机100吸入空气的效率。在一个实施方式中，第五导流板113和第六导流板116可以转动的最大角度为6度。
上述导流板组件20，在驱动第五导流板113和第六导流板116朝相反方向转动的情况下，第五导流板113和第六导流板116相背的一侧形成导流板组件20转动的转轴，第五导流板113和第六导流板116相近的一侧靠近进风口11，使得空气更容易沿第五导流板113和第六导流板116流动至进风口11的周边，有利于增大对空气的吸入速度，从而可满足油烟机100在不同工况下吸入空气的需求。
请参考图17，在某些实施方式中，驱动组件130包括第二驱动件131、第三传动部件133和第四传动部件136。第二驱动件131传动连接第三传动部件133和第四传动部件136。第三传动部件133活动连接第五导流板113。第四传动部件136活动连接第六导流板116。第三传动部件133和第四传动部件136位于第五导流板113和第六导流板116相近的位置。第五导流板113的转轴和第六导流板116的转轴位于第五导流板113和第六导流板116相背的位置。
如此，可方便实现同步带动第五导流板113和第六导流板116的反向转动。
具体地，在图17所示的实施方式中，第三传动部件133包括第一传动杆134，第四传动部件136包括第二传动杆137。第一传动杆134传动连接第五导流板113。第二传动杆137传动连接第六导流板116。基座组件120向第五导流板113提供的转轴为第一轴L1，基座组件120向第六导流板116提供的转轴为第一轴L2。第二驱动件131通过同步带动第一传动杆134和第二传动杆137活动，使得连接第三传动部件133的第五导流板113被第三传动部件133被带动，且第五导流板113会沿第一轴L1进行转动，以及使得连接第四传动部件136的第六导流板116被第四传动部件136被带动地转动，且第六导流板116会沿第二轴L2进行转动。
另外，请结合图17，第三传动部件133活动连接第五导流板113的右侧，第四传动部件136活动连接第六导流板116的左侧，使得第三传动部件133和第四传动部件136位于第五导流板113和第六导流板116相近的位置，进而使得第三传动部件133和第四传动部件136能够靠近设置，不需要将驱动组件130进行分离设置而占据较大的空间和提高驱动的复杂程度，有利于方便实现同步带动第五导流板113和第六导流板116的转动。
在一个实施方式中，第二驱动件131包括电机。在其它的实施方式中，第一传动杆134可以铰接第五导流板113，第二传动杆137可以铰接第六导流板116。
请参考图17和图18，在某些实施方式中，第三传动部件133包括第四主动杆135。第四传动部件136包括第五主动杆138。驱动组件130包括第二连杆132。第四主动杆135活动连接第一传动杆134。第五主动杆138活动连接第二传动杆137。第二连杆132的两端分别活动连接第四主动杆135和第五主动杆138，第二驱动件131传动连接第四主动杆135和第五主动杆138的其中一个。
如此，可有利于简化第二驱动件131的结构。
具体地，在图17和图18所示的实施方式中，第一传动杆134的一端活动连接第五导流板113且另一端活动连接第四主动杆135的一端，而第四主动杆135的另一端则传动连接第二驱动件131。第二传动杆137的一端活动连接第六导流板116且另一端活动连接第五主动杆138的一端，而第五主动杆138的另一端则活动连接驱动基座139。第二连杆132的一端与第一传动杆134为活动连接至第四主动杆135相同的一端，第二连杆132的另一端与第二传动杆137为活动连接至第五主动杆 138相同的一端，使得第二连杆132能够同步带动第四主动杆135和第五主动杆138进行活动。
可以理解，在第二驱动件131仅传动连接第四主动杆135的情况下，通过第四主动杆135、第五主动杆138和第二连杆132之间的连接结构，使得第四主动杆135在活动的时候带动第二连杆132活动，进而通过第二连杆132来带动第五主动杆138与第四主动杆135同步活动，最终使得第一传动杆134和第二传动杆137能够同步转动，第五导流板113和第六导流板116相应地进行同步转动。由于第一传动杆134连接在第五导流板113的右侧，第一轴L1位于第五导流板113的左侧，使得第五导流板113能够沿第一轴L1逆时针转动。同样地，由于第二传动杆137连接在第六导流板116的左侧，第二轴L2位于第六导流板116的右侧，使得第六导流板116能够沿第二轴L2顺时针转动。在第二驱动件131通过第一传动杆134和第二传动杆137进行传动的时候，第一传动杆134会带动第五导流板113向上移动，第二传动杆137会带动第六导流板116向上移动，从而使得第五导流板113和第六导流板116反向同步转动，且相近的一侧靠近进风口11移动。这样就不需要第二驱动件131同时驱动第四主动杆135和第五主动杆138进行活动，从而可简化第二驱动件131的结构，避免设置多个动力来源来分别带动第四主动杆135和第五主动杆138，或将第二驱动件131设置成能够同步转动的多轴结构而增加结构的复杂程度，以及由于整体结构较为复杂而不利于维护和安装。
另外，在一些实施方式中，第二驱动件131可以包括直流减速电机，从而可在驱动第四主动杆135和第五主动杆138的其中一个时，能够带动第四主动杆135和第五主动杆138的另外一个同步活动。相对于使用推杆电机进行推动，采用直流减速电机来带动旋转可以减少设置电机的数量，有利于降低制造成本。
请参考图15-图17和图19，在某些实施方式中，导流板组件20包括梁体140。梁体140包括气孔141和开口142。第五导流板113和第六导流板116相近的一侧具有间隔111。梁体140沿间隔111的延伸方向设置。气孔141开设在梁体140朝向导流板组件20的侧面。开口142朝向进风口11。气孔141连通开口142。在图19中，开口142在梁体140上靠近进风口11的位置而朝上设置，且气孔141和开口142通过梁体140的内侧形成导通。
如此，可提高对空气的导流效率。
具体地，请结合图15和图16，在图15和图16所示的实施方式中，间隔111位于第五导流板113和右侧和第六导流板116的左侧之间的区域并沿前后方向延伸，梁体140沿前后方向延伸设置在间隔111内。在第五导流板113和第六导流板116同步转动的时候，第五导流板113和第六导流板116会由于转动而呈倾斜姿态，空气沿第五导流板113和第六导流板116倾斜的表面可以被导流至梁体140所在的区域。梁体140上开设的气孔141数量为多个。其中一部分气孔141开设在梁体140上靠近第五导流板113的侧面，另外一部分气孔141开设在梁体140上靠近第六导流板116的侧面。
请结合图14和图15，可以理解，在第五导流板113和第六导流板116转动前，气孔141位于第五导流板113和第六导流板116的上方(如图14所示)，在第五导流板113和第六导流板116转动后，气孔141则位于第五导流板113和第六导流板116的下方(如图15所示)，使得空气会沿第五导流板113和第六导流板116呈倾斜姿态的表面导流至梁体140处，并会通过梁体140两侧的气孔141流动至梁体140内侧，再从梁体140内侧向开口142流出，最终朝向进风口11的方向流入进风口11内。
也就是说，在第五导流板113和第六导流板116完成转动后，油烟机100下方的空气即可以自导流板组件20两侧(第五导流板113的左侧和第六导流板116的右侧)的区域流入进风口11，也可以自导流板组件20中部(第五导流板113的右侧和第六导流板116的左侧)的区域通过梁体140上的气孔141和开口142流入进风口11，从而增加了空气的流动支路，进而可提高对空气进行导流的效率。
请参考图19和图20，在某些实施方式中，梁体140包括凸翼143。凸翼143沿间隔111的延伸方向设置在开口142两侧的边沿。在第五导流板113和第六导流板116相近的一侧靠近进风口11移动的情况下，第五导流板113和第六导流板116抵接梁体140对应一侧的凸翼143。
如此，可限定第五导流板113和第六导流板116的活动空间，保证空气的导流效果。
具体地，在图示的实施方式中，梁体140沿前后方向形成有长度，凸翼143沿梁体140的长度方向凸设在梁体140位于开口142两侧的边沿。在第五导流板113和第六导流板116转动的情况下，第五导流板113的右侧会与梁体140左侧的凸翼143抵接，以及第六导流板116的左侧会与梁体140左侧的凸翼143抵接，从而可对第五导流板113和第六导流板116的活动空间进行限定。
可以理解，请结合图15，在第五导流板113和第六导流板116转动而呈倾斜姿态的情况下，如果第五导流板113和第六导流板116转动的角度过大，会使得第五导流板113和梁体140之间形成新的空隙，以及第六导流板116和梁体140之间也会形成新的空隙，位于导流板组件20中部的空 气会沿新的空隙流动至进风口11，而不是完全通过气孔141和开口142流动至进风口11，从而会对梁体140的导流效果产生影响，且容易对空气造成气流扰动，降低导流效率。
在上述基础上，通过设置凸翼143，可对第五导流板113和第六导流板116的活动空间进行限定，使得第五导流板113和第六导流板116不会转动过大的角度，从而可避免上述情况的发生，保证了对空气的导流效果。
而且，在图19和图20中，凸翼143呈向下倾斜设置的结构，从而可配合第五导流板113和第六导流板116转动而形成的倾斜姿态，增加凸翼143和导流板组件20的接触面积，有利于提高凸翼143对第五导流板113和第六导流板116限定效果。
请参考图17、图19和图20，在某些实施方式中，导流板组件20包括封闭件117。封闭件117设置在第五导流板113和第六导流板116相近的一侧。在第五导流板113和第六导流板116相近的一侧靠近进风口11移动的情况下，封闭件117封闭第五导流板113和第六导流板116抵接凸翼143所形成的间隙。
如此，可提高导流效果。
具体地，在图17所示的实施方式中，封闭件117的数量为两个，其中一个封闭件117沿间隔111的延伸方向设置在第五导流板113右侧的边沿，另外一个封闭件117沿间隔111的延伸方向设置在第六导流板116左侧的边沿，两个封闭件117分别在第五导流板113和第六导流板116上相对设置。
在图19和图20中，在第五导流板113和第六导流板116转动的情况下，位于第五导流板113上的封闭件117和对应第五导流板113一侧的凸翼143沿间隔111的延伸方向进行抵接，位于第六导流板116上的封闭件117和对应第六导流板116一侧的凸翼143沿间隔111的延伸方向进行抵接，使得封闭件117能够对导流板组件20和凸翼143之间能够产生的新的间隙沿间隔111的延伸方向进行封闭，从而能够提高凸翼143和导流板组件20之间的封闭效果，避免产生空气扰动，从而能够提高导流效果。
另外，在图19和图20的实施方式中，封闭件117在导流板组件20上形成有凸设的结构。在其它的实施方式中，可以通过调整封闭件117凸设的长度来改变第五导流板113和第六导流板116能够转动的最大角度。封闭件117可以通过螺纹连接、粘合连接、卡扣连接、滑槽连接等方式分别设置在第五导流板113上和第六导流板116上。
请参考图16和图17，在某些实施方式中，基座组件120包括旋转基座121和第三旋转支架126。旋转基座121设于进风口11。第三旋转支架126设于第五导流板113和第六导流板116相背的一侧。第三旋转支架126活动连接旋转基座121以形成转轴。
如此，可实现第五导流板113和第六导流板116的转动。
具体地，请结合图21，在图16和图21所示的实施方式中，进风口11处设置旋转基座121的表面与水平面形成有角度。旋转基座121包括第一基座件122和第二基座件123。第一基座件122设置在第二基座件123的后侧，且第一基座件122沿上下方向的长度大于第二基座件123沿上下方向的长度，使得第一基座件122上用于转动连接第三旋转支架126的转孔127和第二基座件123上用于转动连接第三旋转支架126的转孔127处于同一水平面。
在上述基础上，在图17所示的实施方式中，第三旋转支架126的数量为四个，其中两个第三旋转支架126位于第五导流板113的左侧，且沿前后方向分别设置在第五导流板113的两端；另外两个第三旋转支架126位于第六导流板116的右侧，且沿前后方向分别设置在第六导流板116的两端。第一基座件122的数量为两个，第二基座件123的数量为两个。位于第五导流板113后端的第三旋转支架126转动连接至一个第一基座件122，位于第五导流板113前端的第三旋转支架126转动连接至一个第二基座件123，位于第六导流板116后端的第三旋转支架126转动连接至一个第一基座件122，位于第六导流板116前端的第三旋转支架126转动连接至一个第二基座件123。
可以理解，由于第一基座件122的转孔127和第二基座件123的转孔127处于同一水平面，使得第五导流板113通过第三旋转支架126转动连接第一基座件122和第二基座件123后形成的第一轴L1平行于水平面，以及使得第六导流板116通过第三旋转支架126转动连接第一基座件122和第二基座件123后形成的第二轴L2平行于水平面，且第五导流板113和第六导流板116也位于同一水平面，第五导流板113和第六导流板116能够沿水平方向的轴进行转动的时候也能够呈对称的结构，从而实现第五导流板113和第六导流板116的转动效果，且在转动时也能保证对称结构。第三旋转支架126和第一基座件122或第一基座件122之间可以通过铰接的方式来实现转动连接的效果。
另外，在图17和图18所示的实施方式中，导流板组件20可以通过第五导流板113、第一传动杆134、第四主动杆135和油烟机100整机组成四第二连杆132结构，以及可以通过第六导流板116、 第二传动杆137、第五主动杆138和油烟机100整机组成四第二连杆132结构，从而可通过简单的第二连杆132结构来带动第五导流板113和第六导流板116进行转动。油烟机100整机可以包括基座组件120的全部结构或部分结构。
请参考图14-图16，本申请实施方式提供的一种油烟机100，包括机体10和上述任一实施方式的导流板组件20。油烟机100包括进风口11和机体10。进风口11设于机体10。
上述油烟机100，在驱动第五导流板113和第六导流板116朝相反方向转动的情况下，第五导流板113和第六导流板116相背的一侧形成导流板组件20转动的转轴，第五导流板113和第六导流板116相近的一侧靠近进风口11，使得空气更容易沿第五导流板113和第六导流板116流动至进风口11的周边，有利于增大对空气的吸入速度，从而可满足油烟机100在不同工况下吸入空气的需求。
具体地，请结合图16，在图示的实施方式中，进风口11在机体10上朝下设置，导流板组件20位于进风口11的下方并部分阻挡进风口11。在油烟机100吸入气体时，通过进风口11来吸入位于油烟机100下方的空气，使得导流板组件20能够对向上流动的空气进行导流，并能够根据不同的工况来调整导流板组件20转动的姿态，从而可根据机体10的不同工况来改变流向进风口11的空气流量。
更具体地，在某些实施方式中，油烟机100包括第一工作状态和第二工作状态。油烟机100在第一工作状态下的功率小于在第二工作状态下的功率。在第一工作状态下，第五导流板113和第六导流板116的转动角度小于第一预设角度。在第二工作状态下，第五导流板113和第六导流板116的转动角度大于第二预设角度，第一预设角度小于第二预设角度。
在油烟机100的一个实施方式中，油烟机100可包括具有第一档位和第二档位，第一工作状态可以对应第一档位，第二工作状态可以对应第二档位。在油烟机100的档位为第一档位的情况下，可确定当前需要吸收的油烟较少，不需要以更大的功率来通过进风口11吸入油烟，从而可控制第五导流板113和第六导流板116的转动角度小于第一预设角度，进风口11不会以较大的流量来吸收油烟。在油烟机100的档位为第二档位的情况下，可确定当前需要吸收的油烟较多，需要以更大的功率来通过进风口11吸入油烟，从而可控制第五导流板113和第六导流板116的转动角度大于第二预设角度，使得进风口11处会以较大的流量来吸收油烟。
也就是说，根据不同的功率，可调整第五导流板113和第六导流板116的转动角度，从而可适应地调整对空气的导流效果，进而调节进风口11对空气的吸入幅度。
