具体实施方式
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68描述根据本申请实施例的油烟机100。
油烟机100包括:箱体11、风机组件12、盖板组件12c和驱动组件。
其中,箱体11形成有内腔111及与内腔111连通的第一吸烟口112;风机组件12位于内腔111中,用于产生负压吸力,以使油烟可经由第一吸烟口112吸入至内腔111,而不会造成厨房内充满油烟,以此可提升用户烹饪时的体验。
油烟机1还包括对应第一吸烟口112设置的第一盖板13,第一盖板13具有第一位置及第二位置,第一位置下第一盖板13闭合第一吸烟口112,第二位置下第一盖板13打开第一吸烟口112。如,在油烟机1闲置时,第一盖板13可以处于第一位置以闭合第一吸烟口112,以避免灰尘等经第一吸烟口112进入箱体11的内腔111,或,避免风机组件12暴露造成损坏。而在油烟机1工作时,第一盖板13可以处于第二位置以打开第一吸烟口112,使得风机组件12启动后油烟可经第一吸烟口112吸入至内腔111。

请参阅图1和图2,本申请实施例提出了一种油烟机1,油烟机1包括箱体11及风机组件12。箱体11形成有内腔111及与内腔111连通的第一吸烟口112,风机组件12位于内腔111中,用于产生负压吸力,以使油烟可经由第一吸烟口112吸入至内腔111,而不会造成厨房内充满油烟,以 此可提升用户烹饪时的体验。
请参阅图3和图4,油烟机1还包括传动组件14和驱动件15,传动组件14包括两个以上的第一传动件141和传动杆142,两个以上的第一传动件141间隔设置于内腔111中且均连接传动杆142,用于在传动杆142的带动下实现同步运动。驱动件15连接传动杆142和/或至少一个第一传动件141,用于带动所有的第一传动件141运动,使得第一盖板13在第一位置与第二位置切换。
可选地,两个以上的第一传动件141与传动杆142之间可以通过卡合、过盈配合、焊接、螺接等方式固定连接在一起,以实现两个以上的第一传动件141和传动杆142的运动同步。

本申请设计与第一盖板13连接的多个第一传动件141,相较于单个第一传动件而言,可以使得第一盖板13的开合运动更加顺畅。将多个第一传动件141与传动杆142连接,一方面可以实现多个第一传动件141的同步运动,利于第一盖板13的顺利开合;另一方面可以仅通过一个驱动件15实现多个第一传动件141的驱动,可以降低生产成本。
可选地,传动杆142可以位于箱体11的内腔111且位于风机组件12远离第一吸烟口112的一侧,传动杆142还位于油烟机1使用时第一吸烟口112靠近灶台平面p的一侧。例如,若箱体11的前侧设置有第一吸烟口112,则传动杆142大致设置于箱体11的后侧且位于第一吸烟口112的下方。如此,可以增强传动杆142的隐蔽性,且相较于将传动杆142设置于箱体11的中部而言,可以降低传动杆142的布置方位对箱体11内的风机组件12等结构布置的影响。
可选地,传动杆142可以用于设置于第一平面与灶台平面p之间,其中,第一平面平行于灶台平面p且风机组件12的旋转轴线121位于第一平面内。例如,若箱体11的前侧设置有第一吸烟口112,则传动杆142设置于箱体11的后侧且位于第一吸烟口112的下方,且传动杆142与风机组件12的下半部分对应或位于整个风机组件12的底部,本申请实施例对此并不作出限定。

可选地,第一区域1221的10%以上可以位于第二区域1121。可以大致理解为:进风口122的整个开口所围成的面积中的10%以上的面积将与第一吸烟口112正对,以保证第一吸烟口112处具有足够的负压吸力,进而保证第一吸烟口112处的油烟吸收效果。
需要说明的是,风机组件12包括前板123和与前板123相背设置的后板(图中未示出),前板123上设置有进风口122,风机组件12的前板123可以朝向第一吸烟口112设置,风机组件12的前板123也可以背离第一吸烟口112设置。在风机组件12的前板123朝向第一吸烟口112设置时,可以使油烟机1设计的更薄;在风机组件12的前板123背离第一吸烟口112设置时,可以降低油烟机1使用过程中产生的噪音。
箱体11还可以形成有与内腔111连通的第二吸烟口113,油烟机1还可以包括对应第二吸烟口113设置的第二盖板16,第二盖板16具有第三位置及第四位置,第三位置下第二盖板16闭合第二吸烟口113,第四位置下第二盖板16打开第二吸烟口113。

可选地,风机组件12的旋转轴线121可以与灶台平面p平行,此时,垂直于旋转轴线121的第二平面a将与灶台平面p垂直。需要说明的是,风机组件12的旋转轴线121也可以与灶台平面p相交即可,如,风机组件12的旋转轴线121与灶台平面p之间所夹的锐角大于或等于60°且小于90°,以减轻组装时的精度需求,便于组装。

例如,第一盖板13的内板面具有使用时远离灶台平面p的第一边界线131,第一盖板13可以大致以第一边界线131为转动轴线进行转动,以实现第一吸烟口112的开合。如此,使用时,将油烟机1安装于灶台平面p上方,第二位置下灶台平面p上方的油烟可以受到翻转的第一盖板13的内板面的阻挡而进入到第一吸烟口112内,即,翻转打开的第一盖板13可以对油烟的传输进行导向,可以提升第一吸烟口112的吸烟量,提升油烟机1的使用效果。

实施例二
请参阅图62至图65,实施例二的油烟机与实施例一的油烟机的结构基本相同,不同之处在于:实施例一中,第七传动件141c的第四一连杆1411c、第四二连杆1412c和第四三连杆1413c与第三安装架15c一起构成四连杆机构。本实施例中,第七传动件141c与第三安装架15c可以一起构成六连杆机构,以传动实现第一盖板13的转动传动。
具体地,第四二连杆1412c可以拆分为包括沿其长度方向分布的第一子部1414c和第二子部1415c,第一子部1414c的一端与第四一连杆1411c的第四一连接位1431c处转动连接,第一子部1414c的另一端与第二子部1415c的一端转动连接,第二子部1415c的另一端与第七结构部151c转动连接。第四三连杆1413c可以拆分为包括沿其长度方向分布的第三子部1416c和第四子部1417c,第三子部1416c的一端与第四一连杆1411c的第四二连接位1432c处转动连接,第三子部1416c的另一端与第四子部1417c的一端转动连接,第四子部1417c的另一端与第八结构部152c转动连接。第一子部1414c的中部还与第四子部1417c的中部转动连接。此时,第四一连杆1411c上安装第一盖板13,第二子部1415c远离第一子部1414c的一端或第四子部1417c远离第三子部1416c的一端连接第四驱动件13c的输出轴。
若以第二子部1415c远离第一子部1414c的一端连接第四驱动件13c的输出轴为例,第一盖板13在由第五状态切换至第六状态时,在第四驱动件13c的驱动下,第二子部1415c不仅会带动第三子部1416c远离第四子部1417c的一端向第一吸烟口112外运动,还会带动第一子部1414c远离第二子部1415c的一端向第一吸烟口112外运动。即,第一盖板13在由第五状态切换至第六状态时,在第四驱动件13c的驱动下,连接第一盖板13的第四一连杆1411c的第四一连接位1431c处及第四二连接位1432c处均会朝向第一吸烟口112的外部运动,如此,可以使第一盖板13在向外移动的过程中不易受到箱体11的壳体111的阻碍,即使第五状态下第一盖板13的内板面与第一吸烟口112的开口端面贴合,第一盖板13也可以顺利的打开,可以提升油烟机1的结构紧凑性。

可选地,第四子部1417c的厚度、第二挡板144c的厚度及第二子部1415c的厚度可以大致相等。第三子部1416c的厚度及第一子部1414c的厚度可以大致相等,使得第七传动件141c的厚度尺寸相对轻薄,结构较为整齐、紧凑。其中,第四子部1417c的厚度可以为第四子部1417c沿其转动轴线方向上的长度尺寸,第二挡板144c的厚度、第二子部1415c的厚度、第三子部1416c的厚度及第一子部1414c的厚度可以分别为各自沿第四子部1417c的转动轴线方向上的长度尺寸。
进一步可选地,第二挡板144c上可以设置有第二开口1441c,第四子部1417c转动连接第三子部1416c的一端延伸至第二开口1441c。将第四子部1417c延伸至第二挡板144c的第二开口1441c,可以减少第一盖板13打开时,第二挡板144c与第四子部1417c之间的间隙,可以避免出现夹手现象提升油烟机1的安全性,同时还具有一定的美观性。
可选地,第三安装架15c的第三限位结构153c可以对应第二子部1415c和/或第四子部1417c设置。本申请实施例中,第三限位结构153c对应第二子部1415c设置,且第二子部1415c上设置有卡凸14151c,在第二子部1415c的卡凸14151c运动至抵接第三限位结构153c时,表明第一盖板13运动至第六状态处。
