下面参考附图描述根据本发明实施例的抽油烟机100。
结合图1-图7所示，根据本发明实施例的抽油烟机100可以包括机体1、风机系统2、集油烟罩3、储油盒4、辅助风机和清洗装置5。
具体地，风机系统2与机体1相连且适于产生气流，风机系统2设在机体1的侧部，集油烟罩3与机体1相连，集油烟罩3限定出与风机系统2连通的风道34，集油烟罩3包括间隔开布置的内罩31和外罩32，内罩31和外罩32之间限定出辅助风道33，外罩32上设有与辅助风道33导通的进风口321，内罩31和外罩32的底部间隔开设有与风道34导通的出风口331。
储油盒4沿集油烟罩3的周向延伸地设在辅助风道33内，储油盒4将辅助风道33分隔成上部腔室332和下部腔室333，进风口321和出风口331与下部腔室333导通，内罩31上设有多个与上部腔室332导通的滤油孔311，辅助风机设在下部腔室333内以产生气流，清洗装置5设在机体1上部，清洗装置5上设有与上部腔室332导通的清洗液进口51。

储油盒4设在集油烟罩3的内罩31和外罩32之间且沿集油烟罩3的周向延伸，储油盒4将辅助风道33分隔成上部腔室332和下部腔室333，辅助风机设在下部腔室333内，进风口321和出风口331与下部腔室333导通，内罩31上设有多个与上部腔室332导通的滤油孔311。由此，辅助风机工作以产生气流，气流从进风口321流向下部腔室333，并通过下部腔室333流向出风口331，气流从出风口331流出从而可带动内罩31所包围的空气的流动，以增强集油烟机的吸油烟的风力，在风机系统2的作用下，油烟通过内罩31上的滤油 孔311流向上部腔室332，并排出至室外。通过滤油孔311可实现向对油烟的分离过滤，过滤后的脏污通过重心作用流向储油盒4中，从而可使得锅灶和食物因此干净整洁而不受污染。
清洗装置5设在机体1的上部以用于对集油烟罩3进行清洗，清洗装置5上设有清洗液进口51，清洗液进口51与上部腔室332导通，当需要对抽油烟机100进行清洗时，通过清洗液进口51可清洗装置5内加入清洗液，清洗液在重力作用下向下流动，以对集油烟罩3进行清洗，由此，从而可实现抽油烟机100的自清洗功能。对于清洗液而言，清洗液可以为清洗剂溶液，也可以为热水，能够清洗油污即可。
根据本发明实施例的抽油烟机100，辅助风机工作以产生气流，气流通过出风口331吹出，从而可带动流向集油烟罩3所包围的空气流的流动，以在集油烟罩3的内罩31所包围的空间内形成负压，进而可促进集油烟罩3内的油烟的流动，以达到抽油烟机100对油烟强劲吸取的目的，提高抽油烟机100的吸油烟效果。
储油盒4设在辅助风道33内，通过滤油孔311可实现向对油烟的分离过滤，过滤后的脏污通过重心作用流向储油盒4中，从而可使得锅灶和食物因此干净整洁而不受污染。
清洗装置5设在机体1的上部以用于对集油烟罩3进行清洗，当需要对抽油烟机100进行清洗时，通过清洗液进口51可清洗装置5内加入清洗液，清洗液在重力作用下向下流动，以对集油烟罩3进行清洗，由此，从而可实现抽油烟机100的自清洗功能。
在本发明的一些实施例中，如图7所示，清洗装置5的下端设有出水口52，清洗装置5的出水口52可被构造成，抽油烟机100工作时，清洗装置5的出水口52处于关闭状态，抽油烟机100需要进行冲洗时，清洗装置5的出水口52打开。在本发明的一些示例中，清洗装置5内可设有遮挡件，抽油烟机100正常工作抽油烟时，遮挡件遮挡清洗装置5的出水口52，出水口52处于关闭状态，抽油烟机100需要进行冲洗时，遮挡件移动以打开出水口52。
可选地，出水口52可以包括多个出水孔，通过多个出水孔从而有利于清洗液均匀流向，以对集油烟罩3进行有效冲洗。进一步地，在清洗装置5进行清洗时，风机系统2可选择性进行翻转，从而可将风吹入集油烟罩3中，以进一步地实现对集油烟罩3的有效清洗。
有利地，在清洗装置5内可设有加热装置，通过加热装置可对清洗液进行加热，加热后的清洗液从而更有利于对集油烟罩3的油污进行清洗。进一步地，集油烟罩3清洗后的清洗液可流向储油盒4，从而不仅可对储油盒4进行清洗，而且在清洗结束后，可将储油盒4取出以将清洗液倒出，使得清洗更加方便。
在本发明的一些实施例中，如图6所示，集油烟罩3可以包括第一过滤段35、第二过滤段36和第三过滤段37，第一过滤段的内罩351和外罩352之间限定出辅助风道33，第一过滤段35从上向下的径向尺寸逐渐增大，第二过滤段36形成为沿水平方向延伸的环形，第二 过滤段36外圈的内罩361和外罩362分别与第一过滤段35上端的内罩351和外罩352相连。
第三过滤段的外罩372形成为沿上下方向延伸的柱状，第三过滤段的内罩371从上向下的径向尺寸逐渐增大，第三过滤段37下端的内罩371和外罩372分别与第二过滤段36内圈的内罩361和外罩362相连。通过第一过滤段35、第二过滤段36和第三过滤段37可限定出风道34，油烟通过风道34流风机系统2。
结合图1和图6所示，集油烟罩3具有内罩31和外罩32，内罩31位于外罩32内，集油烟罩3包括第一过滤段35、第二过滤段36和第三过滤段37，第一过滤段的内罩351、第二过滤段的内罩361和第三过滤段的内罩371依次相连以形成集油烟罩3的内罩31，第一过滤段的外罩352、第二过滤段的外罩362和第三过滤段的外罩372依次相连以构成集油烟罩3的外罩32，其中，第一过滤段35位于集油烟罩3的下部，第一过滤段35的上端与第二过滤段36的外端相连，第二过滤段36的内端与第三过滤段37相连，第三过滤段37位于集油烟罩3的上部。
其中，第一过滤段的内罩351和第一过滤段的外罩352之间限定出辅助风道33，辅助风机设在辅助风道33内，第一过滤段35在从上向下的方向上的径向尺寸逐渐增大，从而有利于油烟的吸取的。第三过滤段的外罩372形成为柱形，且沿竖直方向延伸，第三过滤段的内罩371形成为锥形，第三过滤段的内罩371在上至下的方向上径向尺寸逐渐增大。
第二过滤段36形成为环形且沿水平方向延伸，第二过滤段36的外圈与第一过滤段35相连，第二过滤段36的内圈与第三过滤段37的下端相连，具体地，第二过滤段的内罩361的外圈与第一过滤段的内罩351的上端相连，第二过滤段的外罩362的外圈与第一过滤段的外罩352的上端相连，第二过滤段的内罩361的内圈与第三过滤段的内罩371的下端相连，第二过滤段的外罩362的内圈与第三过滤段的外罩372的下端相连。
可选地，第一过滤段35、第二过滤段36和第三过滤段的内罩371上可分别设有滤油孔311。由此，通过第一过滤段的内罩351、第二过滤段的内罩31和第三过滤段的内罩371可对油烟进行分离过滤，从而可提高集油烟罩3的过滤效果，进而可减小油污对风机系统2和吸风通道34的污染，同时也可进一步地使得锅灶和食物干净整洁而不受污染。
可选地，储油盒4可拆卸地设在进风口321和滤油孔311之间，在储油盒4需要进行清理时，从而方便储油盒4的拆卸以及安装。储油盒4的截面形成为S形，储油盒4的上端与第一过滤段的外罩352相连，储油盒4的下端与第一过滤段的内罩351相连。结合图3、图5和图6所示，其中，储油盒4的S形的上部开口朝向第一过滤段的外罩352方向且与进风口321相对应，储油盒4的S形的下部开口朝向第一过滤段的内罩351方向且储油盒4的下部与第一过滤段的内罩351相连，由此，上部腔室332和下部腔室333之间通过S形储油盒4间隔开，进风口321与下部腔室333连通，第一过滤段的内罩351的过滤孔过滤后的油污 可沿内罩31的外壁面流向储油盒4。
进一步地，滤油孔311可以包括多排，多排滤油孔311从上部腔室332的底部向上延伸至第三过滤段37的上部。具体地，每排可包括多个滤油孔311，每排的多个滤油孔311可沿周向方向间隔开设置，多排滤油孔311由上部腔室332的底部向上延伸，且多排滤油孔311可延伸第三过滤段的内罩371的上部，由此，不仅使得滤油孔311分布合理，而且也可保证第一过滤段的内罩351的设置滤油孔311的面积以保证滤油孔311的的过滤效果。进一步地，每排的多个滤油孔311沿周向均匀间隔开设置，从而使得滤油孔311均匀分布，以提高内罩31的油烟的过滤效果，也有利于过滤后的油污的汇聚。
进一步地，第一过滤段的内罩351的外壁面上可设有多个沿内罩31的倾斜方向向下延伸至上部腔室332底部的导油槽。换言之，第一过滤段的内罩351的外壁面上可设有多个导油槽，多个导油槽可沿第一过滤段的内罩351的周向间隔开设置且每个导油槽沿第一过滤段的内罩351的倾斜方向由第一过滤段的内罩351的上端延伸至上部腔室332的底部，具体地，每个导油槽可延伸至储油盒4，这样，多个滤油孔311过滤后的油污可流向导油槽，每个导油槽内的油污通过导油槽最终流向储油盒4内。由此，通过导油槽不仅有利于油污的汇聚和流动，而且也有利于将油污导向储油盒4。
可选地，辅助风道33的截面积从上向下可逐渐增大。由此，不仅有利于集油烟罩3的喇叭形的结构的形成，而且辅助风道33的下端的截面积大于辅助风道33的上端的截面积，由此，可在辅助风道33的下端形成空气放大，便于辅助风机通过辅助风道33的下端的端部结构进行空气放大效果，以吹出强劲风力，对集油烟罩3的油烟区域形成负压，以有利于油烟的吸取。
在本发明的一些实施例中，风机系统2可以包括支撑框架21、电机支架22和电机23，支撑框架21设在机体1的一侧且与机体1相连，支撑框架21内限定有与风道34导通的吸风通道211，电机支架22设在吸风通道211内，电机23设在电机支架22上，电机23的电机轴上设有适于产生气流的风轮231。
具体地，支撑框架21内限定出吸风通道211，吸风通道211连通风道34和室外，电机23和电机支架22设在吸风通道34，通过电机23直接可对电机23进行定位，电机23的电机轴上设有风轮231，电机23驱动风轮231转动以适于产生气流，支撑架与机体1相连且设在机体1的一侧。由此，电机23驱动风轮231转动以在吸风通道34内形成负压，烟气沿风道34通过机体1流向吸风通道34，并在风轮231的作用下排出至室外。
可选地，电机轴可垂直于机体1设置。如图1所示，机体1竖直设置，吸风通道34垂直机体1设置，由此，电机23驱动风轮231可绕水平方向转动，从而不仅有利于电机23驱动风轮231转动以进行吸风，也有利于气流在风道34和吸风通道211之间的流动，而且有 利于风机系统2的安装固定，提高风机系统2的稳定性。
在本发明的一些实施例中，集油烟罩3可形成为开口向下的喇叭形。换言之，集油烟罩3的开口在由下至上的方向上呈收缩趋势，集油烟罩3的下端开口朝向炉灶，在风机系统2的作用下，炉灶产生的油烟可流向集油烟罩3的开口，并可沿集油烟罩3的开口流动，通过喇叭形的集油烟罩3从而可更好地吸取烟气。如图1所示，集油烟罩3的内罩31和外罩32均可形成为喇叭形，外罩32设在内罩31的外侧且与内罩31之间限定出辅助风道33。
可选地，集油烟罩3的内罩31和外罩32绕其轴线旋转延伸角度可小于360°。即集油烟罩3的沿周向方向延伸的角度小于360°。由此，在保证集油烟罩3的集油烟的效果同时可减少集油烟罩3的材料成本，保证集油烟罩3的美观度。优选地，内罩31和外罩32可绕其轴线旋转延伸180°。从而可进一步地保证集油烟罩3的集油烟的效果，并进一步地减少集油烟罩3的材料成本，保证集油烟罩3的美观度。
可选地，外罩32相对于水平方向倾斜的角度可以为θ，0°≤θ≤90°。换言之，外罩32相对水平方向倾斜设置，且外罩32自上而下朝向外侧倾斜。由此，从而有利于集油烟罩3形成为喇叭形，也有利于从进风口321吸气以形成气流。进一步地，外罩32相对于水平方向倾斜的角度θ可以满足30°≤θ≤60°。
可选地，外罩32的下端的截面可形成为优弧形，内罩31的下端的截面形成为劣弧形，内罩31的下端设在外罩32的下端内且与外罩32间隔开形成出风口331。如图3所示，外罩32的下端向内弯曲以形成优弧形，即外罩32的下端形成为弧形且弧形的圆弧大于半圆的弧；内罩31的下端向外侧弯曲以形成弧形且弧形的圆弧小于半圆的弧，内罩31的劣弧形的下端位于外罩32的优弧形的下端内。由此，在内罩31的下端和外罩32的下端之间间隔开以形成出风口331，气流从出风口331流出时可沿内罩31的内壁流动，从而可带动内罩31所包围的油烟的流动。
有利地，出风口331的切线方向与水平面之间的夹角可以为φ，0°<φ≤90°。也就是说，出风口331的切线方向相对于水平方向倾斜。气流从出风口331流出时沿出风口331的切线方向流出，由此，气流从出风口331流出时可带动内罩31所包围的油烟的流动，并可带动油烟朝向风道34流动，以增强抽油烟机100的吸烟风劲。优选地，30°≤φ≤60°
