Description
技术领域
本发明涉及室内通风排气设备技术领域，尤其涉及一种膨胀型消声器和新风系统。
背景技术
新风系统是由能够换气以及净化空气的换气风机、管道以及一些附件组成的一套独立空气处理系统，换气风机将室外新鲜气体经过过滤、净化，通过管道输送到室内，同时将室内污浊的空气排出室外。换气风机在汇聚室内污浊空气和向室内排出新鲜空气的过程中均可能产生压力脉冲和相关噪声，此压力脉冲和相关噪声可通过管道传送至室内而影响室内环境。
为了避免上述问题，现有技术通常在新风系统内连接换气风机和室内的管道中串接膨胀型消声器，以消除沿此管道向室内传送的压力脉冲和噪声。膨胀型消声器的结构如图1所示，包括第一连接嘴01、第二连接嘴02以及位于第一连接嘴01和第二连接嘴02之间的膨胀管03，膨胀管03通过第一连接嘴01和第二连接嘴02连接于管道中，且膨胀管03的截面面积大于第一连接嘴01和第二连接嘴02的截面面积，由此，如图2(a)和图2(b)所示，在膨胀管03与第一连接嘴01之间形成第一变径区域04，在膨胀管03与第二连接嘴02之间形成了第二变径区域05，当压力脉冲波和噪声声波由第一连接嘴01向第二连接嘴02传播时，一部分射入第二变径区域05内并产生反射而由第二连接嘴02向第一连接嘴01传播，与由第一连接嘴01向第二连接嘴02传播的同频率声波因相位相反而相互抵消，由此达到了消声的目的。
但是，由于图1所示膨胀管03的长度固定，因此图1所示消声器仅能消除某些频率的噪声，不能达到宽频带消声的目的。
发明内容
本发明提供一种膨胀型消声器和新风系统，能够达到宽频带消声的效果。
为达到上述目的，本发明提供了一种膨胀型消声器，包括膨胀管，所述膨胀管的两端设有连接嘴，所述连接嘴的截面面积小于所述膨胀管的截面面积，所述膨胀管包括固定管段和伸缩管段，所述伸缩管段靠近所述固定管段的一端与所述固定管段配合套接，并可沿所述固定管段的长度方向滑动以调节所述膨胀管的长度。
本发明还提供了一种新风系统，包括新风主机，所述新风主机与室内之间连接有送风管，所述送风管用于将所述新风主机排出的室外新风送入室内或者将室内污浊空气送入所述新风主机，且所述送风管上串接有消声器，所述消声器为如上技术方案所述的膨胀型消声器。
本发明提供的一种膨胀型消声器和新风系统，由于膨胀型消声器包括膨胀管，膨胀管的两端设有连接嘴，连接嘴的截面面积小于膨胀管的截面面积，因此在膨胀管的两端形成有变径区域，在通过连接嘴将此膨胀管串接于送风管上时，沿送风管传送的噪声和脉冲波可在变径区域处发生反射而与正向传送的声波相互抵消，由此能够达到消声的目的。进一步的，由于膨胀管包括固定管段和伸缩管段，且伸缩管段靠近固定管段的一端与固定管段配合套接，并可沿所述固定管段的长度方向滑动以调节膨胀管的长度，因此膨胀型消声器的长度可调，从而能够消除不同频率的噪声，以达到宽频带消声的效果。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要理解的是，术语“中心”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。在本发明的描述中，除非另有说明，“多个”的含义是两个或两个以上。
参见图7，新风系统包括新风主机20，新风主机20包括壳体，壳体内形成有新风风道(图中未示出)和污风风道(图中未示出)，新风风道内安装有第一换气风机(图中未示出)，壳体上、新风风道的两端分别设有新风入口21和新风排出口22，污风风道内安装有第二换气风机(图中未示出)，壳体上、污风风道的两端分别设有污风入口23和污风排出口24，新风入口21和污风排出口24与室外空间连通，新风排出口22和污风入口23与室内空间连通，且新风排出口22或污风入口23与室内空间之间连接有送风管，送风管上串接有膨胀型消声器10，以避免第一换气风机和第二换气风机产生的噪声和压力脉冲沿送风管传递至室内环境中。
参照图3，图3为本发明实施例膨胀型消声器10的一个具体实施例，本实施例的膨胀型消声器10包括膨胀管11，所述膨胀管11的两端设有连接嘴12，所述连接嘴12的截面面积小于所述膨胀管11的截面面积，所述膨胀管11包括固定管段111和伸缩管段112，所述伸缩管段112靠近所述固定管段111的一端与所述固定管段111配合套接，并可沿所述固定管段111的长度方向滑动以调节所述膨胀管11的长度。
本发明提供的一种膨胀型消声器10，参见图3，由于膨胀型消声器10包括膨胀管11，膨胀管11的两端设有连接嘴12，连接嘴12的截面面积小于膨胀管11的截面面积，因此，如图4所示，在膨胀管11的两端形成有变径区域13，在通过连接嘴12将此膨胀管11串接于送风管上时，沿送风管传送的噪声和脉冲波可在变径区域13处发生反射而与正向传送的声波相互抵消，由此能够达到消声的目的。进一步的，由于膨胀管11包括固定管段111和伸缩管段112，且伸缩管段112靠近固定管段111的一端与固定管段111配合套接，并可沿所述固定管段111的长度方向滑动以调节膨胀管11的长度，因此膨胀型消声器10的长度可调，而根据理论可知，膨胀型消声器10的消声量T与膨胀管11的长度L之间的关系表达式为：
其中，m表示膨胀管11的截面面积与送风管的截面面积的比值，f为噪声声波的频率，当m的值一定时，膨胀型消声器10的消音量T与噪声频率f之间的关系曲线如图6所示，消声量T最大时对应的频率为消声频率f0，为了得到f0，可对T的表达式进行一次求导并等于0，以得到消声频率f0与膨胀管11的长度L之间的关系表达式，通过调节膨胀管11的长度L，即可调节消声频率f0，以适应不同频率噪声的消除，从而达到宽频带消声的效果。
在上述实施例中，伸缩管段112靠近固定管段111的一端可以套接于固定管段111外，也可以套接于固定管段111内，在此不做具体限定。
其中，m取值范围优选为5mm～10mm，m在此范围内时，消声效果较优。
在图3所示的实施例中，为了使膨胀管11能够保持于长度调节后的状态，膨胀型消声器10可以制作为如图4所示结构，即，固定管段111包括管状壳体1111以及贴设于管状壳体1111内壁的一层弹性材料1112，伸缩管段112靠近固定管段111的一端压紧弹性材料1112并配合套接于管状壳体1111内，由此，弹性材料1112可向伸缩管段112施加一个阻尼力，以阻止伸缩管段112在固定管段111内滑动，并使膨胀管11能够保持于长度调节后的状态，而在需要再次调节膨胀管11段的长度时，只需向伸缩管段112施加一个大于此阻尼力的作用力，即可驱使伸缩管段112在固定管段111内滑动。
在上述实施例中，弹性材料1112可以为橡胶、泡棉等等，在此不做具体限定。
进一步的，为了增大消声器的消声量，参见图4，弹性材料1112可以为多孔消声材料，由此，弹性材料1112除了可对伸缩管段112产生阻尼作用之外，还能够消除进入固定管段111内的噪声，从而进一步增大了消声器的消声量。
在图4所示的实施例中，当弹性材料1112为多孔消声材料时，为了在保证固定管段111的导风顺畅性的同时，尽可能多的消除噪声，优选的，弹性材料1112的厚度为5mm～10mm，当弹性材料1112的厚度在此范围内时，既可保证固定管段111的导风顺畅性，又可尽可能多的消除了噪声，而当弹性材料1112的厚度小于5mm时，弹性材料1112的厚度较小，固定管段111的导风顺畅性较好，但是消声效果不佳；当弹性材料1112的厚度大于10mm时，弹性材料1112的厚度较大，消声效果较优，但是导风顺畅性较差。
具体的，弹性材料1112可以为海绵，海绵为常用的消声弹性材料，成本较低，容易实现。
在图3所示的实施例中，为了进一步提高膨胀型消声器10的消声量，如图4所示，伸缩管段112内设有一层消声材料14，消声材料14用于吸收进入伸缩管段112内的噪声。由此，通过在伸缩管段112内设置一层消声材料14，以消除进入伸缩管段112内的噪声，从而进一步提高了膨胀型消声器10的消声量。
其中，伸缩管段112内的消声材料14也可以为弹性消声材料(比如海绵)，也可以为硬质消声材料，在此不做具体限定。
另外，为了在保证伸缩管段112的导风顺畅性的同时，尽可能多的消除噪声，优选的，伸缩管段112内的消声材料14的厚度也为5mm～10mm，当消声材料14的厚度在此范围内时，既可保证伸缩管段112的导风顺畅性，又可尽可能多的消除了噪声，而当消声材料14的厚度小于5mm时，消声材料14的厚度较小，伸缩管段112的导风顺畅性较好，但是消声效果不佳；当消声材料14的厚度大于10mm时，消声材料14的厚度较大，消声效果较优，但是伸缩管段112的导风顺畅性较差。
在图4所示的实施例中，伸缩管段112和固定管段111的截面形状可以为圆形、椭圆形、三角形、方形、多边形等等，在此不做具体限定。但是，为了增大消声器的消声量，优选的，伸缩管段112和固定管段111的截面形状为三角形、方形或多边形，截面为三角形、方形和多边形的管段的相邻两侧壁之间形成夹角区域，当声波进入此夹角区域后，可在此夹角区域内多次反射而损失掉声波的强度，以达到消声的目的。进一步的，为了兼顾伸缩管段112和固定管段111的消声量和导风顺畅性，优选的，如图5所示，伸缩管段112和固定管段111的截面形状为方形，相比于三角形，方形截面的管段的导风顺畅性较优，而相比于多边形，方形截面的管段的相邻两侧壁之间的夹角较小，声波进入此夹角范围内后的反射次数较多，消声效果较优。
本发明实施例还提供了一种新风系统，参见图7，新风系统包括新风主机20，新风主机20与室内之间连接有送风管(图中未示出)，送风管用于将新风主机20排出的室外新风送入室内或者将室内污浊空气送入新风主机20，且送风管上串接有消声器10，消声器10为如上任一技术方案所述的膨胀型消声器10。
由于在本实施例的新风系统中使用的消声器10与上述膨胀型消声器10的各实施例中提供的消声器相同，因此二者能够解决相同的技术问题，并达到相同的预期效果。
在上述实施例中，具体的，送风管可以连接于新风主机20上的新风排出口22与室内之间，也可以连接于污风入口23与室内之间，在此不做具体限定。送风管还可以为两根，其中一根连接于新风主机20上的新风排出口22与室内之间，另一根连接于污风入口23与室内之间，且两根送风管上均串接有消声器。
为了将消声器串接于送风管内，具体的，如图4所示，消声器的连接嘴12内壁贴设有一层弹性材料15，送风管上与消声器连接的端部压紧弹性材料并配合套接于连接嘴内。由此，通过连接嘴将膨胀管串接于送风管内，同时，由于送风管上与消声器连接的端部套接于连接嘴内，因此，在风由送风管进入消声器内时，连接嘴不会对风形成阻碍，从而保证了导风顺畅性。
其中，连接嘴12内壁的弹性材料15可以与固定管段111包括的弹性材料1112和伸缩管段112内的消声材料为同种材料并一体成型，也可以为不同材料且分别成型，在此不做具体限定。
为了进一步提高连接嘴与送风管之间的连接强度，连接嘴的侧壁上开设有定位通孔，送风管的侧壁上与定位通孔相对的位置开设有螺纹孔，还包括定位螺钉，定位螺钉穿过定位通孔连接于螺纹孔上。由此，通过螺钉固定了连接嘴与送风管之间的相对位置，提高了连接嘴与送风管之间的连接强度，防止了连接嘴在风的冲击作用下与送风管脱离。
关于本发明实施例的新风系统的其他构成等已为本领域的技术人员所熟知，在此不再详细说明。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
