技术领域
本公开涉及厨房电器技术领域，尤其涉及一种集烟组件、油烟机、侧吸式油烟机、两侧拢烟中部进风的油烟机、带有风帆的吸油烟机及中央油烟净化设备。
背景技术
油烟机又被称为抽油烟机，是一种用于净化厨房环境的厨房电器，能够将燃气灶燃烧产生的废气和烹饪过程中产生的油烟迅速抽走，并排出室外，以达到净化厨房环境的目的。按照油烟机的工作原理进行划分，可将油烟机分为顶吸式油烟机和侧吸式油烟机两类。由于侧吸式油烟机的进风口离油烟的源头更近，使其能够在第一时间锁定住产生的油烟，排烟效果较为理想，因而受到了大多数消费者的青睐。
现有的侧吸式油烟机中，为了将烹饪过程中产生的油烟集中引导至油烟机的风道，通常，在油烟机的集烟口处均会设置导风板，利用导风板与油烟机本体之间的间隙，实现油烟的集中引入。然而，现有的导风板与油烟机本体之间的间隔有限，使得油烟机的进风面积大大减小，从而极大地削弱了油烟机的吸烟效果。
发明内容

如图1所示，本实施例提供了一种集烟组件，包括具有弧形凹陷部150的拢烟面板(又被称为挡板或者导烟板或集烟面板)100和具有弧形凸出部310的导风板(又被称为前板)300，具体的，导风板300连接在拢烟面板100上且弧形凸出部310与弧形凹陷部150相对，并共同形成相间隔的第一进风口210和第二进风口220。其中，拢烟面板100包括用于将油烟排入至油烟机的风道720中的集烟口110，第一进风口(又被称为右进风口、进风口)210和第二进风口(又被称为左进风口、进风口)220均与集烟口(又被称为吸风口)110连通。
该集烟组件利用拢烟面板100与导风板300之间相对设置的弧形凹陷部150与弧形凸出部310，形成了具有一定吸烟面积的第一进风口210和第二进风口220，使得烹饪过程中的油烟能够及时排出。该集烟组件不仅实现了进风面积的增大，很好地改善了以往油烟机中因导风板300与油烟机本体700之间间隔较小而导致的吸烟效果不理想的情形，增强了油烟机的吸烟效果，从而减少了油烟向厨房环境的肆意流动，提高了用户的体验度；而且，还增加了单位时间内排向油烟机的风道720的油烟量，从而提高了排烟效率，有效地减少了厨房环境中的油烟污染。
此外，该集烟组件结构简单，方案易于实现，成本较低，对于改善厨房环境具有重要意义。
需要说明的是，本实施例中，弧形凹陷部150的“凹陷”和弧形凸出部310的“凸出”均是基于油烟机的正常使用状态(主视状态)进行描述的，即：在油烟机的正常使用状态下，拢烟面板100朝远离用户的 方向形成弧形凹陷部150，导风板300朝靠近用户的方向形成弧形凸出部310。
请继续参照图1，并结合图4，本实施例中，第一进风口210和第二进风口220分别位于油烟机的左右两侧。并且，第一进风口210和第二进风口220连通。这样的设置，减少了对油烟流动过程中的阻挡，使得无论是由第一进风口210进入的油烟还是由第二进风口220进入的油烟均能够顺利地进入至集烟口110中，进一步保证了本实施例集烟组件的工作可靠性。
需要说明的是，本实施例中，第一进风口210和第二进风口220处均设置有用于对油烟进行过滤的过滤网17。过滤网17的设置，对油烟起到了一定的过滤作用，使得经风道720排出至外环境的油烟更为洁净。
请继续参照图1，本实施例中，导风板300的宽度小于拢烟面板100的宽度，以用于将上升的油烟直接引导至第一进风口210和第二进风口220中。这样设置，很好地优化了油烟的运动路径，使得油烟在上升过程中，能够以最短路径被吸入至集烟口110中，进一步提高了本实施例集烟组件对油烟的净化效果。
请继续参照图1，并结合图2，本实施例中，该集烟组件还可以包括位于拢烟面板100与导风板300之间的骨架前板(又被称为骨架或分隔罩)200。具体的，骨架前板200安装在拢烟面板100上，并支撑导风板300，其中。第一进风口210和第二进风口220均开设在骨架前板200上，且分别位于骨架前板200的左右两侧。
该集烟组件在装配过程中，可以先将骨架前板200安装在拢烟面板100上，使其共同形成面板组件，然后，再对导风板300进行装配，以使其能够稳定安装在拢烟面板100的前部。
具体的，本实施例中，导风板300可以与拢烟面板100连接，还可以与油烟机本体(又被称为集烟罩)700连接。其中，导风板300与拢烟面板100或油烟机本体700之间可以为可拆卸连接。在使用一段时间后，可以将导风板300从集烟组件上拆卸以进行清洗，十分方便，大大提高了导风板300的维护效率。具体的，可拆卸连接方式可以包括螺纹连接及卡扣900连接等。
骨架前板200的设置，提高了集烟组件的结构稳定性，在一定程度上避免了外力作用而导致的导风板300损坏的情形，保证了本实施例集烟组件的工作可靠性，并延长了其使用寿命。
需要说明的是，本实施例中，骨架前板200包括相对导风板300层叠设置的板部和近似垂直连接于板部的支撑部，支撑部为两个，且分别位于板部的左右两侧，其中，第一进风口210和第二进风口220分别设置在各支撑部上。
此外，还需要说明的是，本实施例中，第一进风口210和第二进风口220可以是图中示出的仅分别在骨架前板200上设置一个的结构形式，但不仅仅局限于此，还可以采用其他设置形式，如：分别设置多个，其只要是通过设置在骨架前板200上的第一进风口210和第二进风口220，能够实现对油烟的引导吸入即可。
请继续参照图2，本实施例中，骨架前板200可拆卸固定连接在拢烟面板100上。
当需要对集烟组件进行维护时，可以将拢烟面板100、骨架前板200及导风板300拆解为单一的部件，并分别对其进行维护。这样的设置，不仅在一定程度上避免了因清洁死角而导致的清洁不到位的情形，防止了油垢的累积，而且，还使得用户能够选择适宜地点进行维护，避免了因长时间举臂清洁而导致的手臂酸痛，进一步提升了用户的体验度。
请继续参照图2，本实施例中，在拢烟面板100靠近集烟口110的位置处设置有若干固定孔140，骨架前板200靠近拢烟面板100的一侧设置有安装孔(图中未示出)，其中，安装孔的位置及数量均与固定孔140匹配。利用螺纹连接件穿过各安装孔并旋接于对应的固定孔140，即可实现骨架前板200在拢烟面板100上的安装固定。
请继续参照图1和图2，本实施例中，拢烟面板100上可以设置缺口130，其中，导风板300的下端伸入至缺口130中。
这样的设置，使得回落至导风板300上的油液能够顺着导风板300的内表面流入缺口130，并进一步收集，很好地优化了油路结构，而且，还在一定程度上避免了油液由导风板300底部与拢烟面板100之间的缝隙处流出，减少了油液的外溢，从而降低了本实施例集烟组件对烹饪环境造成的污染，进一步提高了用户的体验度。
具体的，本实施例中，缺口130位于拢烟面板100的底部轮廓边缘处。这样的设置，不仅加工制造方便，而且，最大程度地保证了骨架前板200的支撑作用面积，从而进一步提高了本实施例集烟组件的结构稳定性。
需要说明的是，本实施例中，在集烟组件的使用状态下，集烟口110向导风板300的投影可以完全落入 在导风板300上。这样的设置，使得经集烟口110回落至导风板300方向的油液能够完全被导风板300引流，减少甚至是避免了油液的外溢，对烹饪环境起到了进一步的维护作用。
如图4所示，本实施例还提供了一种油烟机，包括油烟机本体700和上述集烟组件。具体的，集烟组件安装在油烟机本体700上，且集烟口110与油烟机本体700的风道720连通。
通过在油烟机中设置油烟机本体700和安装在油烟机本体700上的上述集烟组件，使得在油烟机的正常使用过程中，烹饪产生的油烟能够经第一进风口210和第二进风口220进入至集烟口110，并进一步进入风道720，经风道720的净化作用后，排出至外环境中。
相应的，该油烟机具有上述集烟组件的所有优势，在此不再一一赘述。
需要说明的是，本实施例中，风道720中可以设置离心风机(图中未示出)，在离心风机的驱动作用下，实现对风道720内油烟的净化及向外环境的排出。
请继续参照图1-图3，本实施例中，油烟机本体700还可以包括靠近集烟口110设置的安装板400。具体的，安装板400上设有开口410，用于将由集烟口110进入的油烟引入至风道720中，并且，拢烟面板100可拆卸连接在安装板400上。
请继续参照图2，具体的，本实施例中，拢烟面板100上固设有若干支架120，且各支架120间隔布置，安装板400上对应设置有连接部，利用各支架120在连接部上的连接固定，即可实现拢烟面板100与安装板400的固定连接。
请继续参照图3和图4，本实施例中，该油烟机还可以包括安装在油烟机本体700的底部的油杯600，具体的，伸入至拢烟面板100的缺口130处的导风板300能够将油液引流至油杯600中，以利用油杯600实现对油液的集中收集。
油杯600的设置，实现了对油液的收集，减少了烹饪废油对厨房环境造成的污染，在一定程度上保证了厨房操作环境的洁净度。
请继续参照图1-图4，本实施例中，该油烟机还可以包括用于对油烟机进行控制的开关组件500，具体的，开关组件500可以固设在骨架前板200上，且其按钮510穿出导风板300设置(面向用户设置)。这样的设置，极大地方便了用户对本实施例油烟机的控制，从而进一步提升了用户的体验度。
需要说明的是，本实施例中，开关组件500可以是图中示出的设置在导风板300中间的结构形式，但不仅仅局限于此，还可以设置在其他位置，如：导风板300的左侧或者导风板300200的右侧等，其只要是通过这种位置设置形式，能够实现用户对该油烟机的控制即可。
具体的，本实施例中，导风板300可拆卸固定安装在油烟机本体700上，开关组件500固设在导风板300上。
当需要清洗开关组件500时，可以先将导风板300从油烟机本体700上拆下，然后，再对开关组件500进行清洗操作。该油烟机通过将开关组件500与导风板300集成在一起，利用导风板300的便拆优势，实现了开关组件500与整机的相对分离，便于对开关组件500的清洗操作，改善了以往因开关组件500直接连接在整机上而导致的清洗困难及清洁不到位的弊端，大大降低了故障发生率。而且，这种将开关组件500与能够拆卸的导风板300集成在一起的设置形式，还极大地方便了对开关组件500的检修，缩短了检修周期，保证了油烟机的工作可靠性。
请继续参照图4和图5，并结合图9和图10，本实施例中，开关组件500设置在导风板300靠近集烟口110的一侧，且开关组件500位于导风板300与骨架前板200之间。
通过将开关组件500设置在导风板300靠近集烟口110的一面，不仅在一定程度上避免了因开关组件500外露而造成的磕碰损伤，保证了开关组件500的工作可靠性，而且，还节省了外部空间，使得本实施例油烟机的结构更加紧凑。
此外，通过将开关组件500设置在骨架前板200与导风板300之间，以利用骨架前板200对油烟机周围的油烟进行阻挡，实现了开关组件500与油烟环境的隔离，大大降低了油烟对开关组件500的不利影响，进一步保证了开关组件500的工作可靠性，从而提高了本实施例油烟机的工作可靠性。
请继续参照图9和图10，本实施例中，骨架前板200朝集烟口110方向内陷，并形成一凹腔230，其中，开关组件500位于上述凹腔230中。凹腔230的设置，为开关组件500提供了可靠的安装位置，保证了开关组件500的安装可靠性。
请继续参照图4和图9，本实施例中，在油烟机使用状态下，以平行于水平面的平面(图4中的A-A截 面)剖切凹腔230，形成安装面，螺纹连接件穿过安装面并旋接固定于导风板300。这样的设置，实现了导风板300与骨架前板200之间的装配固定，且结构简单，布局合理。
请继续参照图9，具体的，凹腔230的剖切截面为梯形。其中，安装面即为梯形的两腰，梯形的两腰抵接于导风板300，且梯形的两腰分别朝远离导风板300的中心的方向延伸。
请继续参照图7-图9，本实施例中，导风板300上固设有两个安装架800，且各安装架800分别靠近安装面设置，螺纹连接件依次穿过安装面，并旋接固定于与该安装面相对应的安装架800中。
通过设置截面形状为梯形的凹腔230，使得第一进风口210和第二进风口220的过滤网17被拆下后，两个安装面能够分别暴露在导风板300的左右两侧，为螺纹连接件的安装和拆卸提供了足够的操作空间，使得导风板300能够被快速拆卸，保证了导风板300的拆装便捷性。而且，这种结构形式，还使得在螺纹连接件的安装过程中，骨架前板200具有较好的承力性能，在一定程度上避免了因应力集中现象而造成的骨架前板200损坏的不利情形。
此外，当需要对骨架前板200进行清洁操作时，凹腔230的敞口式设计，还减少了清洁死角，不仅提高了清洁效率，还保证了骨架前板200的洁净度，进一步提高了用户体验度。
为了保证连接可靠性，本实施例中，每一安装架800上均设置有两个连接孔，如图7所示，相应的，凹腔230的各安装面上设置有两个安装孔。
需要说明的是，本实施例中，安装架800可以是上述两个的数量形式，但不仅仅局限于此，还可以采用其他数量形式，如：各安装面处对应设置两个安装架800，其只要是通过这种数量形式的安装架800，能够实现导风板300在骨架前板200上的可靠固定即可。
还需要说明的是，本实施例中，螺纹连接结构简单，连接可靠，且成本较低。具体的，螺纹连接件可以为螺栓或螺钉等形式，本实施例并不对螺纹连接件的具体结构形式进行限制。
本实施例中，导风板300的材质可以为玻璃，并且，安装架800可以通过粘接方式固定在导风板300上。玻璃来源广泛，且热稳定性较高，工作寿命较长。
需要说明的是，本实施例中，导风板300可以是上述玻璃的材质形式，但不仅仅局限于此，还可以采用其他结构形式，如：金属等，此时，安装架800可以通过焊接或螺接等形式连接于导风板300。
本实施例中，导风板300的表面还可以喷涂不粘油涂层。这样的设置，大幅地减少了油液在导风板300表面的附着，便于用户对其进行清洁处理，同时，也降低了用户对导风板300的清洁频率。
请继续参照图8，本实施例中，开关组件500可拆卸固定安装在安装架800上。具体的，开关组件500的边缘设置有连接耳，螺纹连接件穿过连接耳并旋接固定于安装架800中，即可实现开关组件500与安装架800的固定连接。
需要说明的是，本实施例中，开关组件500可以是上述通过螺接固定在安装架800上的结构形式，但不仅仅局限于此，还可以采用其他连接方式，如：卡接或插接等，其只要是通过这种连接方式，能够实现开关组件500与安装架800之间的可拆卸式固定连接即可。
此外，本实施例中，安装架800可以是图8中示出的这种折弯件的结构形式，但不仅仅局限于此，还可以采用其他设置形式，如：块状结构等，其只要是通过设置这种结构形式的安装架800，能够实现导风板300与骨架前板200之间的可靠连接，并实现开关组件500在安装架800上的可靠固定即可。
请继续参照图7、图8和图10，本实施例中，该油烟机还可以包括固设在导风板300底部的卡扣900。如图12所示，卡扣900包括搭接边910，具体的，搭接边910与导风板300呈角度设置，卡扣900伸入至拢烟面板100的缺口中，并搭接在油烟机本体700上，从而实现导风板300在油烟机本体700上的搭接固定。
本实施例中，导风板300在安装时，可以先利用设置在其底部的卡扣900，使导风板300搭接固定在油烟机本体700上，然后，再利用螺纹连接件，将导风板300固定在骨架前板200上。这种卡扣900与螺纹连接件相结合的固定方式，结构简单，便于操作，大大提高了导风板300的安装和拆卸效率。
请继续参照图12，本实施例中，油烟机本体700的底部向内弯折形成一支撑边，当导风板300安装在油烟机本体700上时，搭接边910与支撑边充分接触。这种利用搭接边910与支撑边面面接触的搭接形式，在一定程度上避免了因线面接触而产生的滑移现象，保证了搭接固定的稳定性与可靠性。
请继续参照图12，本实施例中，搭接边910向油烟机本体700的出油孔730方向延伸有引导边920。
引导边920的设置，不仅对骨架前板200上聚集的油液起到了一定的引导作用，使得油液能够被可靠地 引导至出油孔730位置处，以集中排出，很好地优化了油路结构，而且，还在一定程度上避免了油液由导风板300底部与油烟机本体700之间的缝隙处流出，减少了油液的外溢，降低了本实施例油烟机对周围环境造成的污染，进一步提高了用户的体验度。此外，通过设置引导边920，还使得导风板300能够卡接在油烟机本体700底部的支撑边上，进一步保证了导风板300与油烟机本体700之间的连接可靠性。
请继续参照图10，本实施例中，该油烟机还可以包括用于将油烟排出的离心风机。具体的，离心风机的风道720上设置有风道底孔，使得风道720内的油液能够经风道底孔掉落至拢烟面板100的内表面上，并最终沿拢烟面板100的内表面流向出油孔730。
本实施例中，油杯600设置在出油孔730的正下方。
该油烟机工作时，在叶轮710的驱动作用下，燃气灶燃烧产生的废气和烹饪过程中产生的油烟经第一进风口210和第二进风口220进入，经过过滤网17的过滤分离作用，一部分油液在拢烟面板100的阻挡作用下滴落至骨架前板200上，进一步沿骨架前板200的内表面被引流至卡扣900处，并在引导边920的引导作用下流向出油孔730；另一部分经集烟口110上升进入至风道720中的油液，则由风道底孔处滴落至拢烟面板100和骨架前板200上，其中，滴落至拢烟面板100上的油液顺着拢烟面板100流向至出油孔730处，而滴落至骨架前板200上的油液则顺着骨架前板200流向至出油孔730处。上述所有油液汇集后，均通过出油孔730流出至油烟机外部的油杯600中。
如图13-图16所示，本实施例还提供了一种油烟机，包括油烟机本体700、拢烟面板100和收烟进风结构，具体的，收烟进风结构构造成自后向前的凸起形状，凸起内形成有中空部，凸起的左右两侧具有与中空部连通的第一进风口210和第二进风口220，油烟机本体700与收烟进风结构连接用于收集进入中空部的烟气后向外排出，拢烟面板100包括左导烟部170和右导烟部160，且左导烟部170和右导烟部160自下而上由后向前倾斜，产生的油烟在升腾过程中沿着左导烟部170和右导烟部160上升，并由收烟进风结构在中间的凸起形成阻挡从而达到更好的拢烟效果，而进风口设置在收烟进风结构凸起部的左右两侧上，直接将油烟吸进中空部后由油烟机本体700向外排出，减少了油烟逃逸，达到了更好的拢烟排烟效果。
具体的，收烟进风结构两侧自下而上由中心向两侧倾斜，以使得左拢烟区12、右拢烟区11的空间自下而上逐渐缩小从而在上部形成正压区。由于收烟进风结构两侧自下而上由中心向两侧倾斜，使得左拢烟区12和右拢烟区11的下部空间大而上部空间小，烟气在上升过程中，气压逐渐增加，当油烟机开启排风后在收烟进风结构的中空部形成负压，拢烟区正压下的油烟与中空部的负压空气压差会变得更大，使得油烟会更加快速地通过第一进风口210和第二进风口220进入到中空部后排出。
具体的，收烟进风结构包括同时与拢烟面板100连接的左进风板330和右进风板320，以及与左进风板330和右进风板320连接的导风板300，其中，左进风板330、右进风板320和导风板300构成收烟进风结构的外廓，第一进风口210设置在右进风板320上，第二进风口220设置在左进风板330上。导风板300包括上部板350和下部板360，下部板360自下而上由后向前倾斜，弧形凸出部位于上部板350和下部板360之间。如此，在下部板360的下方形成视觉无障碍区A，降低甚至是避免视力阻碍物阻碍使用者观察油烟机下方烹饪厨具的烹饪情况，便于使用者同时查看左右两个区域的烹饪厨具，减小视觉压抑。
本实施例中，开关组件500设置在上部板350上，具体的，上部板350垂直设置，或者，上部板350自下而上由后向前倾斜，且与铅垂面的夹角a小于15°。油烟机正常安装后，导风板300的离地高度在1.4-1.65米之间，整体与大多数用户的眼部离地高度在同一水平区域。并且，通过将开关组件500安装在上部板350上，便于观察和操控。
本实施例中，下部板360与铅垂面的夹角β满足30°≤β≤45°，具体的，夹角β可以选用35°、38°或42°等。这是由于用户在烹饪操作过程中离油烟机较近，当其向下观察时，夹角小于30°时容易阻挡用户的视线，用户需要远离油烟机才容易观察，影响用户体验；若夹角大于45°，则会影响吸烟区域进风口的有效分布，减少进风口面积，影响吸烟效果。
具体的，本实施例中，上部板350和下部板360一体形成，其中，下部板360的下部宽度W1满足80mm≤W1≤150mm，上部板350的上部宽度W2满足280mm≤W2≤400mm。这样的设置，不仅使得中空部具有足够的容纳空间，还能够保证拢烟区的空间，使之协调一致，有效地均衡了拢烟区的拢烟效果和中空部的吸烟效果，从而保证了本实施例油烟机的排油烟能力。
在另一具体的实施例中，如图15所示，不同之处在于左进风板330和右进风板320为弧形面或曲面。这样的设置，在一定程度上增加了第一进风口210和第二进风口220的区域分布面积，进一步提 高了本实施例油烟机的吸油烟效果。
再一个具体的实施例中，如图16所示，左进风板330自后向前由右往左倾斜，右进风板320自后向前由左往右倾斜。这样的设置，有效地增加了进风面积，使得左拢烟区12和右拢烟区11的空间由下往上逐渐缩小，拢烟能力逐渐增强。而且，还使得第一进风口210和第二进风口220设置在朝向烟气升腾方向上，进一步增强了本实施例油烟机的吸油烟效果。
此外，本实施例中，第一进风口210和第二进风口220处设置的过滤网17，可以是可拆卸固定连接在油烟机本体700上。这样的设置，在实现滤除油烟中油脂以减少环境污染的同时，还便于用户对其进行清洁维护。
具体的，本实施例中，该油烟机还包括置于中空部中将中空部分成左腔室和右腔室的隔板(又被称为风帆板)340。隔板340的设置，改善甚至是避免了从左右两侧进风口吸进的油烟互相干扰而降低吸烟效果的情形，从而保证了本实施例油烟机的工作可靠性。进一步地，隔板340能够在外力驱动下滑动或者摆动以改变左腔室和右腔室的空间大小。这样的设置，使得用户可以根据左、右拢烟区11的烟气情况调节左腔室及右腔室的大小，使得当左拢烟区12/右拢烟区11的烟气量较大时，通过滑动或摆动隔板340以增加左腔室/右腔室的空间，以增加左腔室/右腔室的进风量，从而使左拢烟区12/右拢烟区11处的烟气快速排走。
本实施例还提供一种油烟机，如图17-图19所示，该油烟机包括油烟机本体700，油烟机本体700的拢烟面板100上沿其长度方向依次设置有第一进风口210和第二进风口220，其中，第一进风口210位于拢烟面板100的右半部，第二进风口220位于拢烟面板100的左半部。油烟机本体700内设有封堵件13和驱动装置(又被称为驱动组件)14，驱动装置14用于驱动封堵件13对第一进风口210或第二进风口220进行封堵。
本实施例提供的油烟机，包括用于聚拢灶台上左炉头和右炉头烹饪过程中产生油烟的油烟机本体700、用于将油烟吸入油烟机本体700内的第一进风口210和第二进风口220、用于对第一进风口210和第二进风口220进行封堵以控制左右吸烟净化强度的封堵件13和用于驱动封堵件13运动的驱动装置14。通过封堵件13对第一进风口210或第二进风口220封堵对其有效通风面积的改变，风机系统或其他产生吸力的装置产生吸力的大小与进风口的通风面积成正比，从而调节风机系统对第一进风口210和第二进风口220油烟吸力的大小。
第一进风口210设置于拢烟面板100的右半部，相对设置于拢烟面板100的中部，距灶台上右炉头的距离较近；类似的，第二进风口220设置于拢烟面板100的左半部，相对设置于拢烟面板100的中部，距灶台上左炉头的距离较近，相同风力下，第一进风口210和第二进风口220共同作用要比设置在中部的一个进风口对左炉头、右炉头产生油烟的吸收净化效果好。
烹饪时，当左炉头和右炉头产生的油烟量相同时，驱动装置14可以驱动到不影响第一进风口210和第二进风口220进风的位置，如，油烟机本体700内第一进风口210右侧的空间或第二进风口220左侧的空间，风机系统或其他吸风装置产生的吸力将油烟机本体700外侧的油烟经过第一进风口210和第二进风口220吸入油烟机本体700内，并进一步输入公共烟道内做处理；当烹饪时左炉头产生的油烟量大于右炉头产生的油烟量时，开启驱动装置14，控制驱动装置14将封堵件13沿拢烟面板100的长度方向进行运动，对第一进风口210进行封堵，具体的封堵面积可以根据左炉头和右炉头的油烟量差值进行调节，如，右炉头产生油烟量为零，则驱动装置14驱动封堵件13对第一进风口210进行完全封堵；右炉头产生油烟量为左炉头的一半，则驱动装置14对第一进风口210封堵一半面积，如此类推。风机系统产生吸力不变时，第二进风口220的通风面积减小，第一进风口210的通风面积不变，则第二进风口220产生的吸力大于第一进风口210产生的吸力，相应的，第二进风口220对左炉头油烟的吸收净化效果加强，完成对左侧大量油烟的吸收，第一进风口210吸力较小，也可以完成对右炉头产生油烟的吸收净化；具体的，当右炉头不产生油烟时，封堵件13对第一进风口210进行完全封堵，第二进风口220的有效风量可以有效提高70％以上，同时，由于总通风面积减少，风机系统产生的吸力下降，噪音也随之略有下降。右炉头产生油烟量大于左炉头时，调节方式与上述方法类似，这里不再赘述。
通过封堵件13调节左集烟口111和右集烟口112的通风面积，合理分配左右两侧的油烟吸力，在风机系统产生的吸力一定的情况下，能够较好地将左右两侧炉灶产生的油烟吸收干净，提高吸油烟机的吸油烟效果及效率；同时相较在拢烟面板100中部设置一个进风口，第一进风口210和第二进风口220分别距左 炉头和右炉头的距离缩短，减少风力损失，进一步提高对油烟的吸收净化效果。
本实施例中，如图17-图19所示，可以在油烟机本体700内部沿其长度方向设置第一导向件740，封堵件13的底部设置第一限位件750，第一限位件750与第一导向件740滑动连接。封堵件13在驱动装置14的驱动下沿着第一导向件740滑动，第一限位件750对封堵件13的行程起到限位导向作用，提高驱动装置14对封堵件13驱动位置的精确度，也相应提高封堵件13对第一进风口210或第二进风口220的封堵效果，确保封堵件13对风量控制的精度。
为了进一步提高对封堵件13行程的导向作用，本实施例中，还可以在油烟机本体700内部沿其长度方向设置第二导向件760，封堵件13的顶部设置第二限位件770，第二限位件770与第二导向件760滑动连接。
具体的，第一导向件740可以为导轨，第二限位件770为滑槽，滑槽与导轨配合滑动连接；或，第一导向件740为滑槽，第二限位件770为卡接头，卡接头卡入滑槽内，与滑槽滑动连接。第二导向件760和第二限位件770的结构也可以为上述结构，这里不再赘述。
具体的，本实施例中，如图17、图18和图20所示，驱动装置14可以包括驱动件15、第一连杆141、第二连杆142和第三连杆143，油烟机本体700内设有第一枢接座146，封堵件13上设有第二枢接座147，驱动件15的驱动端、第一连杆141、第二连杆142和第三连杆143依次铰接，且驱动件15安装在油烟机本体700内，第二连杆142上靠近第一连杆141的位置枢接有第一枢接座146，第三连杆143的自由端铰接于第二枢接座147。这里是驱动装置14的一种具体结构，驱动件15固定在油烟机本体700内，具体的，可以固定在油烟机本体700的侧壁或油烟机本体700内的风机系统上，驱动件15的伸缩部伸长，通过第一连杆141带动第二连杆142绕第一枢接座146逆时针转动，通过第三连杆143带动封堵件13沿第一导向件740和第二导向件760向右移动；反之，驱动件15的伸缩部缩回时，连杆机构带动封堵件13向左移动，通过控制驱动件15伸缩部的长度可以控制封堵件13的位置，从而实现封堵件13对第一进风口210和第二进风口220的封堵。
驱动装置14除上述结构外，本实施例中，如图19所示，驱动装置14还可以包括驱动件15、第四连杆144和第五连杆145，油烟机本体700内设有第三枢接座148，封堵件13上设有第四枢接座149，驱动件15的驱动端、第四连杆144和第五连杆145依次铰接，且驱动件15枢接于油烟机本体700内，第四连杆144上靠近驱动件15的位置枢接于第三枢接座148，第五连杆145的自由端铰接于第四枢接座149；具体的，可以在油烟机本体700内设置固定架780，驱动件15枢接于固定架780，第三枢接座148固设于固定架780。驱动件15的伸缩部伸出时，第四连杆144绕第三枢接座148顺时针转动，同时通过第五连杆145带动封堵件13沿第一导向件740向左运动；相应的，驱动件15的伸缩部缩回时，连杆机构带动封堵件13向右运动。
本实施例中，可以在拢烟面板100的中部设置集烟口110，集烟口110的外部罩设骨架前板200，骨架前板200将油烟机本体700分隔为左拢烟腔和右拢烟腔，第一进风口210设于骨架前板200的右侧侧面，第二进风口220设于骨架前板200的左侧侧面；骨架前板200上设有隔板340，隔板340将集烟口110分隔为左集烟口(又被称为左烟口)111和右集烟口(又被称为右烟口)112，封堵件13在驱动装置14的驱动下对左集烟口111或右集烟口112进行封堵；具体的，隔板340的形状可以与骨架前板200相匹配，隔板340将油烟机本体700的内部分隔为两个独立的油烟通道，其中，第一进风口210与右集烟口112连通，第二进风口220与左集烟口111连通。隔板340将拢烟面板100分隔为两个相对独立的拢烟腔，将左炉头和右炉头产生的油烟分隔开，第一进风口210和第二进风口220相对独立工作，油烟机工作时，风机系统产生吸力，将左拢烟腔的油烟经过第二进风口220、左集烟口111吸入油烟机本体700内；将右拢烟腔的油烟经过第一进风口210、右集烟口112吸入油烟机本体700内，封堵件13通过对左集烟口111和右集烟口112的封堵，实现对第一进风口210和第二进风口220通风面积的控制，实现对左右两侧油烟吸力大小的控制。
此外，隔板340的设置可以减少左炉头产生油烟与右炉头产生油烟交叉混合不利于第一进风口210和第二进风口220控制净化情况的发生。本实施例中，隔板340的形状与骨架前板200的形状相匹配，隔板340与骨架前板200之间的密封性较为良好，隔板340将骨架前板200内分隔为两个相对独立的油烟通道，以减少风机系统工作时，隔板340两侧油烟吸力在隔板340与骨架前板200之间的缝隙中泄漏进入隔壁烟道，而影响左右两侧吸力控制情况的发生，从而进一步提高封堵件13对左右两侧吸力大小的调节。
本实施例中，为了确保隔板340与骨架前板200之间的密封性，可以在隔板340与骨架前板200接触的边缘设置密封条。
本实施例还提供一种油烟机，如图21-图23所示，油烟机本体700的拢烟面板100的中部设有集烟口110，油烟机本体700的顶板上设有出烟口113，出烟口113与集烟口110连通。集烟口110外设置有骨架前板200，骨架前板200将油烟机本体700分隔为左拢烟腔和右拢烟腔，骨架前板200的左右两侧侧面分别设有左集烟口111和右集烟口112，导风板300与拢烟面板100之间形成的中空部内枢接有隔板340，隔板340插入集烟口110，将集烟口110分隔为左右两个通道口。
上述这种带有隔板340的油烟机，包括用于收集油烟的油烟机本体700，油烟机本体700上设有用于将其分隔为左右两个独立集烟空间的骨架前板200，骨架前板200内设有用于将骨架前板200的内部分隔为两个通道的隔板340，且隔板340可以将集烟口110分隔为左右两个通道口，随着隔板340的转动能够调节两个通道口的大小，而风机系统或其他产生吸力的装置产生吸力的大小与风道口的通风面积成正比，从而调节风机系统对左集烟口111和右集烟口112油烟吸力的大小。
具体的，隔板340上相对的两边可以分别为枢接部241和分隔部242，其中，枢接部241枢接于骨架前板200或油烟机本体700，分隔部242插入集烟口110内，将集烟口110分隔为左右两个通道口。使用时，吸油烟机安装在灶台上方相应的位置，当烹饪过程灶台上左侧炉灶与右侧炉灶产生的油烟量相同时，转动隔板340的枢接部241，隔板340的分隔部242随之转动，将隔板340的分隔部242调节到集烟口110的中部，隔板340将集烟口110的左右两侧分隔为两个通风面积相等的通道口，开启风机系统，风机系统产生强大的吸力，油烟机本体700外部的油烟在吸力作用下进入油烟机本体700内，并经过出烟口113被输送到指定位置进行处理或排放。具体的，左侧炉灶上产生的油烟向上运动，经过左集烟口111进入，在风机系统的吸力作用下沿着隔板340经过集烟口110左侧的通道口进入油烟机本体700内，并通过出烟口113排出油烟机本体700；类似的，右侧炉灶上产生的油烟在风机系统的吸力作用下，依次经过右集烟口112、集烟口110右侧的通道口、油烟机本体700、出烟口113排出油烟机本体700。由于隔板340将集烟口110分隔为大小相同的两个通道口，因此风机系统对两个通道口产生的吸力相同，通过左集烟口111和右集烟口112对左拢烟腔和右拢烟腔油烟的吸力相等。
当左侧炉灶和右侧炉灶上产生的油烟量不同时，以左侧炉灶产生的油烟量较大为例，此时，向右转动隔板340，隔板340的分隔部242随之转动，集烟口110左侧的通道口通风面积大于右侧的通道口，开启风机系统，风机系统对左侧通道口产生的吸力大于右侧通道口产生的吸力，相应的，左集烟口111对左拢烟腔的油烟的吸力较大，完成对左侧大量油烟的吸收，右烟口对右拢烟腔的油烟的吸力较小，也可以完成右侧油烟的吸收，从而实现左侧炉灶产生油烟量大于右侧炉灶产生油烟量时，通过调节隔板340角度以调节集烟口110被隔板340分隔的两个通道口的大小，合理分配左右两侧的油烟吸力，在风机系统产生的吸力一定的情况下，能够较好地将左右两侧炉灶产生的油烟吸收干净，提高吸油烟机的吸油烟效果及效率。
本实施例中，如图22所示，隔板340的形状可以与骨架前板200相匹配，隔板340将骨架前板200的内部分隔为两个独立的油烟通道。隔板340的形状与骨架前板200的形状相匹配，隔板340与骨架前板200之间的密封性较为良好，隔板340将骨架前板200内分隔为两个相对独立的油烟通道，以减少风机系统工作时，隔板340两侧油烟吸力在隔板340与骨架前板200之间的缝隙中泄漏进入隔壁烟道，而影响左右两侧吸力控制情况的发生，从而进一步提高隔板340角度转动对左右两侧吸力大小的调节。为了确保隔板340转动过程中与骨架前板200之间的密封性，可以在隔板340与骨架前板200接触的边缘设置密封条。
本实施例中，如图21-图23所示，骨架前板200可以包括底座，隔板340枢接于底座，导风板300的内侧壁安装有驱动装置14，驱动装置14用于驱动隔板340转动，油烟机的开关组件500设置在导风板300的外侧壁上，开关组件500与驱动装置14电连接。
具体的，开关组件500可以包括左转向开关和右转向开关。驱动装置14可以驱动隔板340转动，进而改变隔板340的分隔部242两侧通道口的大小，实现对左拢烟腔和右拢烟腔吸力大小的调节，使用时，当左侧炉灶产生油烟量较大时，按下右转向开关，驱动装置14驱动隔板340向右转动，隔板340的分隔部242随之向右转动，集烟口110中隔板340左侧的通道口面积变大，右侧通道口的面积减小，隔板340转动一定角度后关闭右转向开关，完成隔板340的角度调节；打开风机系统，集烟口110中左侧的通道口吸力较大，相应的，左集烟口111对左拢烟腔油烟的吸力较大，右集烟口112对右拢烟腔油烟的吸力则较小。类似的，右侧炉灶产生油烟量较大时，按下左转向开关，控制隔板340向左转动即可，这里不再赘述。驱动装置14的设置，不仅提高了控制隔板340角度的操作便捷度，而且电控制精确度和灵敏度高。
需要说明的是，本实施例中，开关组件500可以是按钮510的设置形式，但不仅仅局限于此，还可以采 用其他形式，如：触屏开关，其只要是通过开关组件500的这种设置形式，能够实现对油烟机的自动控制即可。
本实施例中，可以在油烟机本体700上设置油烟感应器，油烟感应器电连接有微处理器，微处理器电连接有驱动装置14，驱动装置14用于驱动所述隔板340转动。油烟感应器对油烟机本体700上左拢烟腔和右拢烟腔内的油烟量进行监测，当油烟感应器感应到左拢烟腔的油烟量较大时，可以将电信号传递给微处理器，微处理器接收到电信号通过计算得出隔板340需要转动的方向和角度，并将该控制信号传递给驱动装置14，驱动装置14打开，驱动隔板340向右转动一定角度后停止转动，完成隔板340对通道口大小的调节；右拢烟腔油烟量较大时，工作原理与此类似，这里不再赘述。
油烟感应器的设置灵敏度、精确度均较高，且能够实时根据油烟量的大小进行调节，大大减少了操作人员的劳动力。
本实施例中，如图22-图24所示，隔板340上开设有容纳槽，容纳槽与驱动装置14相匹配，隔板340的底部设有第一枢接轴243，底座上设有枢接槽，枢接槽与第一枢接轴243相匹配；容纳槽的底部设有第二枢接轴244，第二枢接轴244的自由端端面上设有卡接槽245，卡接槽245与驱动装置14的输出端相匹配。这里是驱动装置14与隔板340连接的一种具体形式，驱动装置14固定在骨架前板200上，驱动装置14的输出端卡入第二枢接轴244的卡接槽245内，其中，第一枢接轴243与第二枢接轴244共轴线；开启开关组件500，驱动装置14的输出端转动，并通过卡接槽245带动第二枢接轴244、隔板340绕第一枢接轴243转动，从而实现驱动装置14对隔板340角度转动的驱动。具体的，这里的驱动装置14可以选用驱动电机。
这里需要说明的是，驱动装置14驱动隔板340转动的结构并不局限于此，只要能实现驱动隔板340转动的结构都可以。
本实施例中，如图21所示，可以在油烟机本体700的上部固设装饰罩16，装饰罩16将出烟口113罩设于其内。装饰罩16的设置，一方面，可以对排气管与油烟机本体700连接处起到保护作用，以减少外界因素对其造成损坏而影响吸油烟机工作情况的发生；另一方面，也可以提高吸油烟机的外表整洁度，改善用户体验。
本实施例还提供一种中央油烟净化设备，包括公共烟道和上述油烟机，其中，油烟机的排气管与公共烟道连通。
本实施例提供的中央油烟净化设备，包括用于抽吸厨房油烟的油烟机和用于输送油烟的公共烟道，具体的，油烟机可以为多个，多个油烟机之间相对独立工作；使用时，工作状态的油烟机将抽吸的厨房油烟通过排气管排入公共烟道中，公共烟道将多个油烟机汇集的油烟输送到后续净化设备中进行油烟处理。其中，使用该油烟机，设置左右两个进风口，距相对应炉头的距离缩小，相同风力下，净化效果好；且当左炉头产生油烟量与右炉头产生油烟量不同时，可以通过封堵件13调节第一进风口210和第二进风口220的通风面积，合理分配左右两侧的油烟吸力，在风机系统产生的吸力一定的情况下，能够较好地将左右两侧炉灶产生的油烟吸收干净，提高吸油烟机的吸油烟效果及效率。最后应说明的是：以上实施例仅用以说明本公开的技术方案，而非对其限制；尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本公开实施例技术方案的范围。
