摘要： 江苏光芒开创油烟机"顶侧双吸"新时代
江苏光芒集团结合市场的需求变化，针对传统塔形油烟机占用空间大、易撞头、难清洁，近吸式油烟机集烟腔小，油烟易逃逸等难题进行科研攻关，首家研发出“顶侧双吸”式油烟机，一举解决了中国厨房净烟的所有难题，成为业内科技含量最高、吸烟效果最好。
该产品采用系统性的静音优化设计，电机采用了日本NSK超静音滚珠轴承，耐磨损、噪音低，并具有防过热保护等功能，给消费者营造出了安静祥和的厨房环境，实现了对传统厨房家电产品技术革新的同时，更迎合了青年一代的品味追求。
目前，光芒公司已将该产品申报发明专利和新型实用专利。据了解，这款新型油烟机现已热销江苏、浙江、安徽、山东、河南等市场。
