本申请要求美的集团股份有限公司于2018年01月30日提交的、发明名称为“排烟装置”的、中国专利申请号“201810091039.7”的优先权。
技术领域
本申请涉及排烟技术领域，特别是涉及一种排烟装置。
 背景技术
目前，抽油烟机在市场上基本进入普及状态，在重点城市对于抽油烟机的需求正在向高端化、个性化、智能化发展。影响抽油烟机实际效果的主要关键部件包括风机、风道、吸口结构等，其中对于不同安装位置的风机布置方式，以及流道结构形状的外观性和制造工艺性的要求，导致空气在流动过程不可避免存在不均匀分布状态，影响速度和压力的分布，进而导致在抽油烟机吸口部位附近流场的非均匀分布状态，不利于吸油烟效果。
此外，目前市场上抽油烟机为了获得更好的抽油烟效果，日益朝着大风量，高背压的趋势发展，以此提升油烟吸口的负压覆盖范围但是，通常抽油烟机的噪声水平和风量有直接关系，风量越大，噪声越大，用户的体验感就越差。
当前市场上的抽烟烟机的类型多种多样，按照结构形式大致可以划分为顶吸式、近吸式、集成式等，对于顶吸式烟机，为了增强拢烟效果，主要覆盖在烹饪器具的上方，整机深度大约515mm，在进行烹饪的过程中容易碰头，影响用户体验。
对于近吸式烟机虽然整机深度低于500mm, 但是为了弥补顶部拢烟面积不足的问题，其下侧斜面距离烹饪器具较近，占据了烹饪空间，同样影响了用户操作体验。
对于集成式吸油烟机，虽然结构紧凑，不会占据烹饪空间，但是对于爆炒状态下的大量油烟很难做到油烟零泄漏，如果靠提升风量来实现油烟零泄漏的效果，以及靠提升风量来提高吸烟效率，不仅将带来噪声升高的问题，而且过大的风量将加剧燃气的消耗量。

下面参考图1-图11详细描述一下根据本申请实施例的排烟装置10。
如图1、图2、图3、图4、图5、图6、图7和图11所示，根据本申请实施例的排烟装置10包括：风机组件1和集烟罩2，风机组件1可以包括：风机11和风机壳12，风机11设置于风机壳12内，风机11竖向放置，由此，风机11的放置方式区别于传统风机的放置方式，传统风机的放置方式为横向放置，也就是说，本申请的风机11的轴向为前后方向，传统风机的轴向为上下方向，由此，这样设置一方面可以改善排烟装置10内部的空气流动，另一方面可以缩短排烟装置10在前后方向上的深度，从而可以有利于排烟装置10趋向于小型且高效的方向发展。
风机壳12仅具有朝向后方敞开的第一进烟口13，或者说，风机壳12的后表面设置有第一进烟口13，在风机壳12的其他表面未对应设置有其他进烟口。本申请的排烟装置的风机组件1仅设置一个第一进烟口13，这样可以在有限空间内提升排烟装置10的整体拢烟效果。
集烟罩2设置在风机组件1的下方，集烟罩2具有第二进烟口21和第二出烟口22，第二进烟口21朝向下方，第二出烟口22与第一进烟口13连通，其中，集烟罩2可以包括：导流板23，导流板23位于第二进烟口21的上方，而且导流板23在从前向后的方向倾斜向上延伸设置，导流板23可以起到导流作用。
其中，导流板23的外观结构可以为平面、曲面和弧面中的一种，也可以是以上几何面的组合。
在本申请的一些实施例中，如图8所示，当排烟装置10工作时，油烟运动至第二进烟口21处后，在第二进烟口21处抽吸气流的作用下，油烟会通过第二进烟口21进入到集烟罩2内，然后经过导流板23的作用，导流板23会把油烟导向第二出烟口22，这样油烟会继续向上运动进入到第一进烟口13，当油烟运动至风机11的入口处时，在风机11的作用下，油烟会经由烟道出口6排出排烟装置10，可以实现排烟装置10的排烟工作。
在上述的油烟流动过程中，导流板23可以引导油烟在排烟装置10的内部气流流道内流动，不会导致排烟装置10内局部产生涡流，能够减少气动阻力损失，可以提高排烟装置10的吸烟效率，也能够降低排烟装置10工作时的噪音，从而可以提升用户满意度。
另外，也能够使在第二进烟口21之外的附近区域气流流动形态更加顺畅，可以扩大拢烟范围，从而可以减少排烟装置10以外的气流流动阻力损失，进而可以实现更优的吸油烟效果，。
由此，通过风机组件1和集烟罩2配合，能够减少排烟装置10的气动阻力损失，可以提高排烟装置10的吸烟效率，也能够降低排烟装置10工作时的噪音。与传统的排烟装置相比，在相同风量下，本申请可以实现零漏烟的效果，该排烟装置10在工作时的风量大于等于13.8m3/min时，厨房内的油烟可以完全被吸除。
在本申请的一些实施例中，导流板23的前下端与水平面之间的夹角为a，a至少是35°且不超过90°，a满足关系式：35°≤a＜90°，需要说明的是，导流板23和水平面之间所构成的夹角在不同的角度范围之内可以调节，满足上述角度范围的导流板23可以较好地引导集烟罩2内的油烟运动，可以进一步地减少排烟装置10内涡流的产生，可以有效降低排烟装置10的噪音。
在本申请的一些实施例中，导流板23的前下端与水平面之间的夹角为至少是35°且不超过60°，a可以满足：35°≤a≤60°，需要解释的是，导流板23的前下端与水平面之间的夹角的调节范围可以在35°至60°之间，如此设置能够把油烟更好地导入排烟装置10内，也能够更好地防止局部涡流的产生，从而可以更好地减少气动阻力损失。
在本申请的一些实施例中，如图3所示，风机壳12可以包括：下板14，下板14的后端与导流板23止抵，而且下板14与导流板23的止抵处距离导流板23的后上端预定距离，如此设置能够使下板14止抵在导流板23处，下板14可以对导流板23起到支撑作用，当排烟装置10工作时，能够使导流板23的位置更加稳固，可以降低导流板23的振动，从而可以进一步降低排烟装置10工作时的噪音。
在本申请的一些实施例中，如图2所示，在水平面上的投影，现有的集烟罩的前端超过了风机壳的前端，而本申请集烟罩2的前端不超过风机壳12的前端，如此设置能够使排烟装置10的深度缩短，可以减小排烟装置10所占体积，从而可以减小排烟装置10占据的烹饪空间。
在本申请的一些实施例中，如图3-图7所示，集烟罩2还可以包括：进烟格栅24，进烟格栅24限定出第二进烟口21，如此设置能够使第二进烟口21的设计更加合理，可以使油烟快速地被吸进排烟装置10，从而可以进一步提升排烟装置10的工作性能。
在本申请的一些实施例中，如图3-图5所示，进烟格栅24在从前向后的方向上倾斜向下延伸设置，进烟格栅24的倾斜角的设置范围为0°到60°，如此设置可以增强排烟装置10的滤油效果。
在本申请的一些实施例中，如图1-如图4所示，排烟装置10还可以包括：进烟通道3，进烟通道3位于集烟罩2的后下方，进烟通道3的下端形成第三进烟口31，进烟通道3的上端敞开设置，而且进烟通道3的上端与第一进烟口13连通，其中，排烟装置10工作时，风机11为气流输送提供动力，油烟在上升过程中，首先被第三进烟口31中的抽吸气流作用，能够使油烟更加靠近第三进烟口31，也能够使部分油烟在抽吸气流的作用下，进入到进烟通道3内，在抽吸气流的作用下，油烟继续向上流动，油烟从进烟通道3流到风机11处，最后从烟道出口6排出排烟装置10外部，可以更好地吸走厨房内的油烟。
在本申请的一些实施例中，排烟装置10还可以包括：烟道壳4，烟道壳4安装于风机组件1和集烟罩2的后方，烟道壳4内限定出烟道41，烟道41连通第二出烟口22和第一进烟口13，进烟通道3与烟道41连通，如此设置能够保证油烟可以被抽吸气流带到风机11处，从而可以满足排烟装置10的工作性能。另外，通过烟道壳4和集烟罩2的配合，可以使得排烟装置10的吸油烟效果更好，拢烟效果更好。其中，烟道壳4、集烟罩2和风机壳12可以为分体式结构。其中，壳体5可以包括罩设于风机组件1处的罩设壳，罩设壳的后端和集烟罩2的后端可以形成有安装环板，安装环板与烟道壳4配合安装，采用此种安装方式安装简单，安装效率高。
其中，未进入第三进烟口31中的部分油烟，在热空气的浮力作用下继续上升，油烟可以经由第二进烟口21进入到烟道41内，如图9和图10所示，从图中可以清楚看到，不仅在进烟格栅24和第三进烟口31之间气流流线顺畅得被抽吸进入排烟装置10的内部，而且在进烟格栅24的上方，如图9中基于CFD的风机11区域流体流线分布情况所示，气流也被顺畅的抽吸进入排烟装置10的进烟格栅24，这种特殊的内部导流流道设计，不仅大大增强了吸油烟效果，而且该排烟装置10舍弃了传统的排烟装置所使用的蝶翼板，使得排烟装置10的外观更加整洁，易于清理油污，并且降低了生产与制造成本。
在本申请的一些实施例中，如图3和图4所示，第三进烟口31处设置有至少一个导流翼板311，需要解释的是，第三进烟口31处导流翼板311的设置数量大于等于一个，例如：导流翼板311可以为三个，导流翼板311的外观结构可以为平面、曲面和弧面中的一种，也可以是以上几何面的组合，导流翼板311具有导流的作用，能够使气流更加顺畅得流动，可以避免在进烟通道3中的气动损失，并且，也能够避免排烟装置10内产生局部涡流，可以提升排烟装置10的工作效率。
在本申请的一些实施例中，导流翼板311可以为多个，而且多个导流翼板311相邻的两个导流翼板311间隔开设置，位于最下方的导流翼板311的宽度大于其上方的导流翼板311的宽度，如此设置能够使油烟顺利地被吸进排烟装置10，可以进一步提升导流翼板311的工作性能。
在本申请的一些实施例中，排烟装置10还可以包括：壳体5，壳体5罩设于风机组件1和集烟罩2，壳体5在前后方向上的深度为c，其中，c满足c≤350mm，例如：现有的排烟装置在前后方向上的深度为515mm，本排烟装置10在前后方向上的深度小于等于350mm，如此设置能够使排烟装置10的深度缩短30%以上，可以进一步缩小排烟装置10的体积。
其中，如图3-图6所示，排烟装置10还可以包括：气流入口总成7和导流前端8，导流前端8与气流入口总成7连接，导流前端8的外观结构可以为平面、曲面、弧面，也可以是以上几何面的组合，气流入口总成7上可以设置有油槽9，排烟装置10在吸油烟的过程中，油烟中的油可以储存在油槽9内。
另外，如果导流板23的前下端与水平面之间的夹角a的角度范围有所调整，或者进烟格栅24的倾斜角也有所调整，导流板23与气流入口总成7直接连接，此时无导流前端8。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
