油烟严重危害人类健康,如何高效捕集油烟是抽油烟机设计的核心,近吸式抽油烟机相比于顶吸式效率大大提高,但是控制油烟扩散的效果仍然较差,通过分析提出利用导流板技术、空气幕技术、射流技术三种方式促进近吸式抽油烟机最大限度的排净油烟,以此达到高质量的家居生活标准.%The lampblack is harm to human- health and how to efficiently capture lampblack is the core of the range hood design. The suction efficiency of nearly suction style is greatly improved when compared to the top suction style, but the effect of controlling the spread of smoke is still poor. This paper proposed by analyzing the guide plate, air screen, jet technology to maximum the ability of suction, in order to achieve the high quality living standards.
