吸油烟机的风机通常包括风机和安装风机并设有气流通道的蜗壳。所述风机通常由电机驱动，电机通过一根轴和叶轮连接。使用时，由于电机带动风机转轮动引起震动，并通过其与吸油烟机壳体的连接使壳体产生共振，并且风机中流动的空气的摩擦撞击也产生噪声。因此，吸油烟机的噪音来源主要包括两个方面，第一方面是风机本身的噪音如震动产生的噪音，第二方面是气流产生的噪音。
目前公知的吸油烟机的降噪技术和方法是一方面优化设计，改进风机的性能，使风机自身的噪声和振动下降，从而达到整机噪声下降的目的，另一方面是提高整机有关零部件的刚性，特别是外壳薄板件的刚性，抑制其共振噪声的产生，采用上述方案，可基本解决风机本 身产生的噪音。而对于气流产生的噪音，目前还没有办法。

具体实施方式
下面结合附图对本发明作进一步的说明。
参考图1，本实施例的一种新型降噪静音油烟机，其主要包括机壳1、过滤网2、油杯3、抽气系统(未绘示)和位于机壳1顶板的排烟管6，根据实际的需要，本实施例的新型降噪静音油烟机还可增加操作面板4和照明灯5或者其他油烟机功能部件，这里不再赘述。
参考图2-图4，作为本发明中新型油烟机静音降噪排烟管的一个具体实施，本实施例的一种新型油烟机静音降噪排烟管，其包括定型外壳61，及安装在外壳两端的管座62，所述的两管座62间由多孔消声材料632覆盖在环形的钢丝支架631上制作而成的波纹管63连接，所述的波纹管63与外壳61之间填充有隔音层(所述隔音层可以采用薄铝板或隔音棉66，或者其他的隔音材料或结构)。
其中本实施例中定型外壳61起到对波纹管63的定型支撑作用。
而作为具体的实施例，所述的钢丝支架631可由钢丝卷绕成螺旋形，其外圈覆盖多孔消声材料632后形成皱褶状的波纹管63。加工该波纹管时，按照一定螺距将消声材料贴覆在钢丝支架上，当钢丝的螺距缩小时，就在相邻两钢丝圈间形成皱褶。
另外一个具体实施例中，所述的钢丝支架631可为两种直径不同的圆形钢丝圈，两种钢丝圈相间分布与多孔消声材料632贴覆，形成皱褶状的波纹管63。利用两直径不同的圆形钢丝圈直径的直径差，形成波浪起伏状的波纹管。
需要说明的，本实施例中所述的多孔消声材料可为岩棉、玻璃丝 棉、无纺布或为棉纱布，上述各种材料均具有许多细小孔，产生对声波的吸附作用，从而实现静音降噪作用，实际中也可以采用其他的消声材料，而作为可行的其他实施例，波纹管也可以采用弹性伸缩的螺旋管代替，可实现管道伸缩便利，便于油烟排放，且安装简单，这里不再赘述。
另外，本实施例中所述的波纹管63与隔音棉66间还设有铝箔隔热层68，隔热层能有效隔绝烟气中的热量向外传递，避免因外壳过热而导致排烟管周围的墙壁，橱柜等被加热导致其发黄。
本实施例的工作原理如下：从油烟机内排出的烟气经过排烟管向外排放，油烟机产生的噪音在经过排烟管时，声波首先与波浪状波纹管侧壁发生碰撞，从而被分散，起到第一重降噪作用、然后分散的声波被多孔消声材料3及隔音棉吸附，起到第二重静音降噪的作用。因此经过两重隔离，最大限度降低发散到排烟机噪声。
另外，参考图2、图3、图5和图6，作为本发明新型油烟机静音降噪排烟管的另一个具体实施，本实施例的新型排烟管，其同样包括定型外壳61及安装在外壳上下两端的管座62，上下两端的管座62之间通过中空的弹性伸缩螺旋管或波纹管63连接，所述弹性伸缩螺旋管或波纹管63内壁设置有吸声材料，所述吸声材料表面上间隔一定距离开设有细孔64，所述细孔64与所述伸缩螺旋管或波纹管的波谷间形成吸声空腔65，如图6所示，作为一个具体的实施例，所述细孔64可为三角形孔，实际使用时，声能通过细孔64进入波谷间的吸声空腔后转换成热能而被吸声，而为了提高吸声效果，还可在吸声 空腔中设置辅助的消声材料，例如海绵、带孔的板材、吸音泡沫等，这里不再赘述。
另外，需要说明的，本实施例中所述的波纹管63与定型外壳61内壁之间填充有隔声层(例如采用薄铝板或隔音棉66)，为了降低振动噪声，在所述隔声层(即隔音棉66)与所述的波纹管63之间还可设减震层，作为具体实施例例如采用丁基橡胶层作为减震层，这里不再赘述。
同样的，所述的减震层与所述的波纹管63间还设有铝箔隔热层68。
同样的，所述波纹管63可为环形的钢丝支架631制作而成，在所述钢丝支架631上还覆盖有多孔消声材料632，而所述的多孔消声材料632可为岩棉、玻璃丝棉、无纺布或为棉纱布。
同样的，所述的钢丝支架631可由钢丝卷绕成螺旋形，其外圈覆盖多孔消声材料632后形成皱褶状的螺纹管或波纹管。
同样的，所述的钢丝支架631可为两种直径不同的圆形钢丝圈，两种钢丝圈相间分布与多孔消声材料632贴覆，形成皱褶状的螺纹管或波纹管。
以上显示和描述了本实用新型的基本原因和主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各 种变化和改进，如吸声空腔的结构，螺旋管或波纹管的结构，制作波纹管使用的多孔消声材料，隔音棉的材料等，这些变化和改进都落入要求保护的本实用新型范围内。
