Description

吸油烟机
本申请要求于2018年01月30日提交中国专利局、申请号为“201810089347.6”、发明名称为“吸油烟机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及家用电器领域，具体而言，涉及一种吸油烟机。
背景技术
抽油烟机目前在市场上基本进入普及状态，在一些城市对于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，其中由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的问题，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。相关技术中，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，同时克服高层楼宇排烟管道高阻力可能引起的油烟现象。当风量提高以后，虽然获得了更好的吸除油烟效果，但是同样带来噪声增大的问题。上述吸油烟机在工作时，气流在经由吸口进入到抽油烟机流道中时，由于空气流向发生突变，导致局部产生涡流，甚至存在逆流现象，与空气流动方向相反，影响了进气量，而且产生了额外的气动噪声，降低了产品的工作效率。在最恶劣的状态下，虽然风机的转速提高，但是由于局部涡流的存在，抽油烟机的空气流量不仅没有增加，而且噪声反而增大。

具体实施例中，第一吸烟口30和第二吸烟口40的面积不同，故，单位时间内由第一吸烟口30和第二吸烟口40吸入的气流流量不同。可根据具体实际使用情况调节导流部20背离第一吸烟口30的一侧与水平面120的夹角a的取值范围来，决定第三流道100内的气流的流动形态，进而可减少流动阻力损失，同时能够使在第一吸烟口30之外的附近区域气流流动形态更加顺畅，扩大拢烟范围，减少吸油烟机1外流场的流动阻力损失，实现更优的吸油烟效果。
具体实施例中，本申请的吸油烟机1的结构设置，不仅大大增强了吸油烟机1的吸油烟效果，而且使得整机外观更加整洁，易于清理油污，并且降低了生产与制造成本，提升了产品使用性能及市场竞争力。
具体实施例中，如图15所示，炉灶130加热放在其上的器具110，器具110因受热而产生油烟，吸油烟机1抽吸油烟，箭头指示了油烟气流的流动方向，吸油烟机1工作时，第二吸烟口40的抽吸气流带动油烟运动，使得油烟逐步聚拢于吸油烟机1的抽吸范围内，并利用第二吸烟口40抽吸入部分油烟，使得部分油烟进入第一安装本体102的第一流道80内后汇入第二安装本体104的第二流道90，此时部分未被抽吸的油烟在热空气的浮力作用下继续上升，进而被第一吸烟口30抽吸入导流部20的第三流道100内，并最终使油烟汇入第二流道90。即，通过合理设置油烟的流动流道，引导油烟在吸油烟机1的流动方向，进而降低了吸油烟机1工作时因气流流向变化所产生涡流概率，减少了气流流动时的气动阻力损失，降低了产品运行时的噪声，强化了产品的拢烟能力，使得油烟可顺畅地被流入吸油烟机1，进而增大了吸油烟机1单位时间内的抽吸风量，提升了产品的工作效率、使用性能及市场竞争力，且降低了能耗。
具体实施例中，如图16和图17所示，箭头示出了第一流道80内、第二流道90内、第三流道100内及第一吸烟口30附近的气流的流动方向。通过合理设置吸油烟机1的结构，使得在第一吸烟口30的栅格50处和第二吸烟口40的栅格50处的气流流线顺畅得被抽吸进吸油烟机1内部，并且在第一吸烟口30附近区域(特别是第一吸烟口30上方)的气流也被顺畅地抽吸进入第一吸烟口30的格栅50。该结构设置不仅大大增强了吸油烟机1的吸油烟效果， 而且使得产品外观更加整洁，易于清理油污，降低了生产与制造成本。
