本文分析了目前我国市场上烟机主要类别,并指出小户型家庭厨房烟灶设备在使用中存在的问题。进而通过化学方法,利用紫外线分解油烟,实现烟灶内部空气的净化与循环。在此基础上,探索提高油烟分解率的方法,并总结小户型家庭特点及需求,设计出能够避免污染公共大气环境的环保优化型烟灶一体机。 This article analyzes the main categories of hoods in the current market in our country and points out the problems existing in the use of small-sized home kitchen hoods. Then through chemical methods, the use of UV fumes decomposition, to achieve internal air purification and recycling stoves. On this basis, explore ways to improve the decomposition rate of fumes, and summed up the characteristics and needs of small-sized family, designed to avoid pollution of the public atmosphere environment optimization fumigation machine.
