Description

一种隔声通风窗
技术领域
本发明属于建筑门窗领域,具体涉及一种隔声通风窗。 
背景技术
随着城市化的发展,工业和交通噪声已成为影响人们正常生活和健康的一个主要因素,为了解决这一问题,人们做出了许多的努力,并发明了各种形式的隔声通风窗,其中,最为主要的就是采用通风的窗户型材与隔声玻璃相组合,比如,夹胶玻璃、中空玻璃以及真空玻璃组合构成,其隔声量虽然可达到30dB(A)以上,但是其无法阻隔500Hz以下的低频段噪音,而影响人们正常生活和健康最主要的噪音频段就集中在500Hz以下,并且这种通风窗户型材与隔声玻璃组合而成的窗户满足不了室内外通风换气的要求。
目前市场上也出现了设置有通风器的隔声窗,这种隔声窗一般是在现有窗户的窗框与玻璃之间安装通风器,虽然它解决了室内外通风换气的问题,但是其隔声量较小,同上述隔声通风窗一样,也无法阻隔500Hz以下的低频段噪音,不但占据了窗户的有效采光面积,并且通风器与窗户的窗框之间的密封性也难以保证。
发明内容
针对上述不足,本发明提供一种隔声通风窗,该隔声通风窗不但能有效阻隔低频段噪音,而且其通风换气性能和密封性能都较好。
本发明是通过这样的技术方案来实现的:一种隔声通风窗,该隔声通风窗包括带有进风口的外窗、带有出风口的内窗,以及位于内窗与外窗之间并与外窗和内窗均相连接的消声腔体;该消声腔体内悬挂有通过电机控制的百叶消声片,该百叶消声片在电机的作用下可旋转或者收拢。
所述百叶消声片由若干个微穿孔叶片组成,这些微穿孔叶片采用绳状物牵连和悬挂并相互平行布置,其外形类似于百叶窗的结构,并且这些微穿孔叶片最好悬挂于消声腔体的中间;上述电机可采用管装电机,其可安装于消声腔体的顶部中心,电机与微穿孔叶片相连接组合成电动百叶窗的结构;所述百叶消声片采用微穿孔铝片;电机工作控制这些叶片旋转,使它们处于垂直或水平位置,即:当这些微穿孔叶片旋转到垂直位置时,这些微穿孔叶片便组成一个微穿孔面板,该微穿孔面板便将内窗与外窗之间的腔体分割成两个空腔,分别是外窗与微穿孔面板之间形成的A腔和内窗与微穿孔面板之间形成的B腔,并且该B腔同时也是一个共振腔,其可作为一个微穿孔消声器,以隔断低频段噪音;当这些微穿孔叶片旋转到水平位置时,这些叶片之间便形成一个阻性消声器,其可进一步削弱从窗外进入窗内的噪音。
所述内窗与外窗之间的距离最好是大于或等于100mm,理论和实践都证明,当外窗与内窗之间的距离小于50mm时,会在窗内形成“驻波”,由于驻波是由频率和振幅均相同、振动方向一致、而传播方向相反的入射波和反射波叠加而成,而反射发生在两介质的交界面上,因此,将内窗与外窗之间的距离设置为大于或等于100mm,其隔声量可提高10~15dB(A),故可大大提高对低频噪音的隔断率。
为了进一步提高该隔声通风窗的吸声效果,所述消声腔体的内侧面设置有凹槽,该凹槽内填充有高效吸声体,比如吸声棉或者其他吸声材料。
进一步,所述进风口的四周和消声腔体内表面的四周均设置有吸声体,该吸声体可采用吸声棉或者其他吸声材料。
所述外窗的进风口和消声腔体内表面均设置有用以固定所述吸声体的止挡。
所述消声腔体可采用铝件拉制成型,当然也可根据实际情况采用其他材料制作成型。
所述消声腔体的两侧面设置有安装凹槽,该安装凹槽内设置有密封橡胶条,所述消声腔体通过该密封橡胶条与内窗和外窗相连接,不但可提高消声腔体与内窗和外窗之间的密封性,而且还可在密封橡胶条与内窗、外窗之间形成一个密封的消声空间,进一步消除噪音。
为了防止窗外的蚊虫或灰尘等通过进风口进入到隔声通风窗内,所述外窗在进风口处固定设置过滤网,同时还可以在外窗上设置固定该过滤网的止挡。
所述内窗在出风口处设置有风机,该风机镶嵌在内窗上部的窗框内,并采用螺钉固定在内窗的窗框上,风机与内窗的窗框之间的空隙可用发泡剂填塞,以进一步保证密封性,窗外的新鲜空气通过外窗的进风口进入到消声腔体后,通过该风机渊源不断地送入到室内,进一步提高了该隔声通风窗的通风性能,也不影响有效采光面积。
由于采用了上述结构,本发明的有益效果如下:
(1)本发明提供的隔声通风窗在内窗与外窗之间设置了消声腔体,并且该消声腔体内悬挂有通过电机控制、可实现旋转或者收拢的百叶消声片,这些百叶消声片在旋转至垂直位置时便可组成一个微穿孔面板,其与内窗之间形成的共振腔可作为一个微穿孔消声器,从而吸收从进风口进入到消声腔体内500Hz以下的低频段噪音,克服了现有技术中难以阻隔的低频段噪音的问题;当这些百叶消声片在旋转至水平位置时,这些百叶消声片之间便形成一个阻性消声器,不但可进一步削弱从窗外进入窗内的噪音,同时还能保证该隔声通风窗的通风性能,对有效采光面积也无影响。
(2)进一步的是,该隔声通风窗的内窗与外窗之间的距离大于或等于100mm,充分利用了驻波的叠加特性,其隔声量可提高10~15dB(A),从而大大提高了低频段噪音的阻碍率,提高整个隔声通风窗的隔音效果。
(3)同时,本发明还在消声腔体的内侧面,以及进风口的四周均设置有吸声体,该吸声体可灵活采用各种高效吸声棉,从而不管是在噪音从进风口进入到消声腔体的阶段,还是在噪音已经进入到消声腔体内的阶段,都可以对新鲜空气中夹杂的噪音进行全程吸收,进一步提高整个隔声通风窗的隔音效果。
(4)本发明提供的隔声通风窗还具有良好的热交换性能。在本发明中,所述百叶消声片采用了微穿孔铝片,当这些铝片旋转至垂直位置组成一个微穿孔面板时,其将内窗与外窗之间的腔体分割成两个空腔,即A腔和B腔,由于A腔的温度接近室外温度,B腔的温度接近室内温度,因此在A腔与B腔之间就存在温差,这种温差在冬季或深秋时节表现得尤为明显,例如在东北严寒季节,窗外温度为零下30℃,窗内温度为25℃,两者之间相差55℃,而A腔和B腔中的空气可通过上述微穿孔铝片进行较好的热交换,从而预先提高欲进入到室内的空气温度;反之在夏季,这些微穿孔铝片可预先降低欲进入到室内的空气温度,从而达到节能减排的目的。
(5)更进一步的是,上述百叶消声片采用微穿孔铝片,当其旋转处于垂直位置时,不但可充当窗帘的作用,而且在夏天还可以很好地反射阳光,阻隔热量进入室内。

具体实施方式
为了更加清楚地理解本发明的目的、技术方案及有益效果,下面结合附图对本发明做进一步的说明,但并不将本发明的保护范围限定在以下实施例中。
如图1至图4所示,一种隔声通风窗,该隔声通风窗包括带有进风口1的外窗2、带有出风口3的内窗4,以及位于内窗4与外窗2之间并与外窗2和内窗4均相连接的消声腔体5;该消声腔体5内悬挂有通过电机控制的百叶消声片6,该百叶消声片6在电机的作用下可旋转或者向上收拢;所述百叶消声片6由采用绳状物牵连和悬挂并平行布置的叶片组成,所述叶片采用微穿孔铝片;所述内窗4与外窗2之间的距离大于或等于100mm;所述消声腔体5的内侧面设置有凹槽7,该凹槽7内填充有吸声体8;所述进风口1的四周和消声腔体5内表面的四周均设置有吸声体8;所述外窗2的进风口1和消声腔体5内表面均设置有用以固定所述吸声体8的止挡9;所述消声腔体5采用铝件拉制成型;所述消声腔体5的两侧面设置有安装凹槽10,该安装凹槽10内设置有密封橡胶条11,所述消声腔体5通过该密封橡胶条11与内窗4和外窗2相连接;所述外窗2在进风口1处固定设置有过滤网12;所述内窗4在出风口3处设置有风机13。
当电机控制所述百叶消声片6旋转到垂直位置时,这些百叶消声片6便组成一个微穿孔面板,该微穿孔面板便将内窗4与外窗2之间的腔体分割成两个空腔,分别是外窗2与微穿孔面板之间形成的A腔和内窗4与微穿孔面板之间形成的B腔,并且该B腔同时也是一个共振腔,该共振腔作为一个微穿孔消声器,其可隔断从窗外进入窗内的低频段噪音;因此,从进风口1进入到消声腔体5内的噪音便通过两种途径消除:第一,一部分噪音被上述微穿孔消声器吸收;第二,另一部分噪音被设置在消声腔体5的内表面和进风口1的四周的吸声体8吸收;同时上述微穿孔面板还可以当窗帘使用。
当电机控制所述百叶消声片6旋转到水平位置时,这些百叶消声片6之间便形成一个阻性消声器,不但可进一步削弱从窗外进入窗内的噪音,同时还能保证该隔声通风窗的通风性能。
