具体实施方式
图1-图11为本发明第一个实施例的结构示意图。其中，图1为整体结构立体示意图，图2为整体结构左视图(拆除左侧板后的内部结构示意图)，图3为整体结构主视图；图4-图6为局部结构示意图，图7-图11为局部结构放大示意图(8为通风隔道设计参数示意图、图9为图10旋转后显示底部的结构示意图，图11为内部结构剖视放大图)；图中箭头方向为烟汽流动方向。
图1-图3显示，本例中，一种厨房抽油烟机的除油装置，包括设置于抽油烟机迎风面01B下侧的油烟分离器，油烟分离器呈倾斜状态安装固定，油烟分离器的高端1D安装在迎风面01B下侧而低端1C固定在后墙壁03上，油烟分离器左、右两侧封闭，油烟分离器、后墙壁03及迎风面01B构成一个负压空间，油烟流经油烟分离器之后进入负压空间最后经抽油烟机吸风口01B1被抽排出去，在后墙壁03上位于油烟分离器低端1C的下侧还安装集油槽01A。
图3-图8显示，油烟分离器是由导流页片1.1逐个对齐排列串接固定而成的导流格栅，导流页片1.1左、右侧壁呈波浪曲面，导流页片1.1的横截面呈波浪结构，导流页片1.1左、右侧壁上分别设置有若干 用于串接的定位构件1.11，相邻导流页片之间具有通风间隙，通风间隙构成通风隔道1.15，通风隔道1.15呈波浪曲折状态，导流格栅的下侧为油烟入口1.112A而上侧为油烟出口1.112B，油烟经油烟入口1.112A进入导流格栅、在曲折路径中反复与导流页片1.1的侧壁碰撞然后从油烟出口1.112B排出进入所述负压空间。图5显示，本例中，导流页片1.1纵向呈直线型结构。本发明提示，由于导流格栅可以在内部形成一个大容积的空间，因此具有瞬间禁闭并吸纳大量烟雾的能力，并且由于通风隔道自下往上呈曲折状态，油烟在通风隔道中流动时多次与侧壁发生碰撞，因此油雾粘附的机率大增，使油脂的分离率可以得到明显的提高。
图3显示，本例中，油烟分离器由4个格栅模块1、2、3、4排列组成，格栅模块1、2、3、4分别独立安装固定。将油烟分离器拆分为若干个格栅模块，可以将大尺寸变为小尺寸，方便日常安装和拆除。
图3显示，本例中，在油烟分离器的左、右两侧分别设置有左侧板1.114A及右侧板1.114B。设置左侧板1.114A及右侧板1.114B可以防止油烟从侧面进入油烟分离器，同时还可以进一步提高拢烟效果。
图8显示，本例中，通风隔道1.15具有6个折弯点。本发明提示，在其它实施例中，优选的，通风隔道折弯点可以选取2-6个。
本发明提示，综合考虑油烟分离器的整体尺寸和油烟中油雾的碰撞粘附效果，本例中，油烟分离器的倾斜安装角(与水平面的夹角)优选10°-50°；油烟分离器的厚度B(即下底面1A与上顶面1B之间的高度)可以选取20mm-120mm；通风隔道可以参照以下尺寸：折弯角α可以选取90°-130°；通风隔道的宽长比即宽度A与折弯长度L之比为0.2-0.5(即0.2≤A/L≤0.5)；宽度A的绝对尺寸可以选取2.5mm-30mm。通风隔道的设计直接影响通风效果，在油烟分离器的厚度不变的情况下，宽度A尺寸变小，通风截面变小，通风阻力变大；宽长比A/L变小，通风阻力变大；折弯点越多，通风阻力变大。而通风阻力越大则油雾的粘附效果越好。
图5及图7显示，本例中，导流页片1.1的横截面(横向)还设置有筋板1.12，筋板1.12沿纵向间隔设置。本例中，用于串接的定位构件1.11为插销1.11A与定位孔1.11B，定位构件1.11沿纵向间隔设置。在导流页片1.1的一侧(左侧壁或右侧壁)设置插销1.11A而在另一侧的对应位置上设置定位孔1.11B(定位孔即带孔的插座)，将插销1.11A插入定位孔1.11B中使导流页片逐个对齐串接。本发明提示，在导流页片1.1上沿纵向间隔设置若干筋板1.12是本发明的优选方案，其目的增加导流页片的强度。
本发明提示，本例中，导流页片1.1应当采用注塑加工，因此，其上面的筋板1.12和插销1.11A及定位孔1.11B与页片本体等都可以一体式注塑成型。在导流页片1.1上一体式注塑成型设置串接定位构件是本发明的优选方案，目的是在制作格栅模块时使导流页片的对齐串接更加容易。可以根据需要串接形成不同横向宽度的油烟分离器。
本例中，油烟分离器、后墙壁03及迎风面01B构成一个负压空间。本发明提示，在其它实施例中，若在炉灶后面增设立面壁板，由立面壁板替代后墙壁03并与油烟分离器及迎风面01B构成一个负压空间， 则与本发明属于等同替换的技术方案。
图4、图9、图10、图11显示，本例中，格栅模块1的两端还分别设置有包套1.113A及1.113B,包套呈槽状结构。图中显示，包套1.113A的侧壁1.113A1、1.113A2具有与相邻导流页片相匹配的波浪曲面(包套1.113B结构类似)，包套将串接后的各个导流页片包合固定。本例中，通过定位构件1.11将导流页片逐个对齐串接之后，包套1.113A及1.113B可以很容易地包合在格栅模块1的两端。因为导流页片1.1在串接之前是单件状态，如果没有定位构件的串接定位，很难将各个导流页片逐个对齐，也很难将包套1.113A及1.113B包合在格栅模块1的两端。本例中，定位构件1.11发挥对齐串接作用，为了拆装方便，插销1.11A与定位孔1.11B之间不需要紧配合。两端的包套发挥固定作用，可以将串接后的各个导流页片1.1固定成一个整体。日常拆装清洁时，只需将两端的包套拆开，就可以很容易将各个导流页片拆散进行清洁。
图3、图9、图10、图11显示，本例中，包套1.113A上还设置抓手1.113A5。抓手1.113A5作为受力点，可以作为格栅模块拆装时手指的受力点。图中显示，由于导流页片1.1纵向呈直线型结构，而油烟分离器(格栅模块)呈倾斜状态安装固定，因此包套1.113A及1.113B具有斜切结构。包套1.113A及1.113B的斜切结构可以使格栅模块的两端分别与后墙壁03及迎风面01B更加贴合。
图2显示，本例中，由于油烟分离器呈倾斜状态安装固定，油烟分离器的油烟入口1.112A具有倾斜面1.112A1，目的是使导流页片1.1侧壁上粘附的油渍能够向低端1C流淌并最后滴落在集油槽01A中。
本例中，抽油烟机为顶吸式结构，本发明提示，因为格栅模块呈倾斜状态安装固定，因此，参照本例的安装结构，本发明也可以应用于侧吸式的抽油烟机。
本发明提示，可以采用螺钉、磁吸、卡扣等通用固定方式将格栅模块呈倾斜状态安装固定。
现有顶吸式抽油烟机由于结构原因宽度较大，使用过程中容易发生碰头。本发明提示，由于油烟分离器呈倾斜状态安装固定，因此抽油烟机的机体宽度可以缩小进而避免碰头。
本发明提示，由于导流页片由注塑而成，可以对其进行表面处理，以便在日常使用过程中更容易清洁油污。
图12、图13为本发明第二个实施例的结构示意图。其中图12整体结构立体示意图，图13为局部结构示意图。图中显示，与第一个实施例不同的是，本例中，导流页片1.1的纵向呈直线型并且一端呈折弯结构(导流页片1.1呈弯刀型结构)。本例中，由于导流页片1.1在B端呈折弯结构,因此，包套1.113A具有斜切结构、而包套1.113B的贴合面1.113B1不具有斜切结构。
图14为本发明第三个实施例的通风隔道设计示意图。与图8相比较，与第一个实施例不同的是，本例中，依照烟气流动的方向，通风隔道1.15的折弯角依次变小。本例中，第一折弯点1.110A对应的折弯用为a1、第二折弯点1.110B对应的折弯用为a2、第三折弯点1.110C对应的折弯用为a3、第四折弯点1.110D对应的折弯用为a4,角度数值为a1＞a2＞a3＞a4(其中，a1可以选取110°-130°，a4可以选取85° -95°)。本例中，折弯角依次变小可以使油烟分离器在油烟的流动过程中逐渐捕捉到颗粒越来越小的油雾。
图15、图16为本发明第四个实施例的局部结构示意图。其中图15为局部结构放大示意图，图16局部结构截面放大示意图。与图14相比较，与第三个实施例不同的是，本例中，所述导流页片1.1的左、右侧壁还设置若干纵向隔板1.18。本例中，导流页片1.1的下边缘1.17A还具有纵向淌油板1.17A1(纵向淌油板呈水平设置，板的宽度优选3-6毫米)，纵向淌油板1.17A1发挥淌油并使油滴向端头流动汇集的作用，使导流页片侧壁上粘附的油渍能够沿淌油板表面流向导流页片的端头而不是从下边缘1.17A向下垂直滴落。本例中，设置纵向隔板1.18是为了提高烟气中油雾的碰撞粘附效果。本发明提示，本例中，由于设置了纵向隔板1.18，通风隔道的宽长比可以加大。
图17为本发明第五个实施例的局部结构放大示意图。与图15相比较，与第四个实施例不同的是，本例中，导流页片1.1还纵向排列设置通孔1.19。通孔1.19使格栅模块1在内部构成横向连通孔，使各个导流页片之间彼此相通，因而可以使各个通风隔道的负压达到平衡，并且使各个通风隔道在油烟的流动过程中发挥协同作用。
图18为本发明第六个实施例的局部结构截面放大示意图。与图16相比较，与第四个实施例不同的是，本例中，导流页片1.1呈平面直板结构。通过设置若干纵向隔板1.18将相邻的导流页片1.1与1.2之间所构成的直线型通风隔道分隔成反复曲折状态。
图19、图20为本发明第七个实施例的结构示意图。其中图19为整体结构立体示意图，图20为局部结构放大示意图。与第一个实施例不同的是，本例中，在格栅模块1的上顶面1B及下底面1A还分别横向设置卡条1.111。图20显示，卡条1.111上阵列设置有1.111A卡槽。1.111A卡槽与导流页片1.1的下边缘1.17A及上边缘1.17B卡合固定。
本发明提示，本发明中述及的“水平”及“垂直”不等于数学概念上的“水平(0度)”或“垂直(90度)”，仅用于解释本发明的技术内容，在实施方案时不限定在数学意义上的“水平(0度)”或“垂直(90度)”。并且，以上仅为本发明列举的部份优选实施例。除此之外，根据本发明提出的技术方案，还可以对导流页片的截面形状、纵向结构、定位构件的结构以及包套、卡条等进行相应的调整从而实现更多的实施例。凡是以本发明提出的技术方案为基础而进行的等同替换或调整或改进，均应包含在本发明的保护范围之内。
