下面参考图1-图4描述根据本申请实施例的消音器20，该消音器20能够实现对宽频带的空气噪音的消除和弱化，极大地提高了消音器20的消音效果。
具体地，消音器20具有消音腔21，消音腔21包括多个间隔开的消音子腔210，消音器20具有分别与多个消音子腔210一一对应地连通的多个消音入口，消音入口处设有朝向对应的消音子腔210内伸入的消音插管22，多个消音子腔210中的至少两个的内腔容积不同。
其中，多个消音子腔210中至少两个消音子腔210的容积不同，从而使得多个消音子腔210具有不同的消音效果。需要说明的是，不同容积的消音子腔210能够实现对不同频率的空气噪音进行降噪。
由此，通过在消音器20内设置多个消音子腔210，且多个消音子腔210中至少两个消音子腔210的容积不同，以使该消音器20能够实现对不同频率的空气噪音进行吸收，利于提升消音器20的宽频消音效果，且结构简单，安装方便，同时多个消音子腔210组合设于消音器20内，便于节省安装空间，利于提高消音器20的空间紧凑性和结构整体性，以实现消音器20的小型化设计，在目标频段较低或空间尺寸有限的情况下，能够提高消音器20的空间利用率，保证良好的声学性能和消声效果。
例如，将多个消音子腔210中的两个或三个或者更多个设置为容积不同，以使多个消音子腔210中的两个或三个或者更多个分别具有不同的消音效果，如可对应不同频率的空气噪音。当然，也可将多个消音子腔210的容积均设置为不同，以最大化地丰富消音器20的消音频率范围，如图3和图4中所示，每个消音器20均形成有四个消音子腔210，且四个消音子腔210的容积大小均不同，从而使得四个消音子腔210能够对不同频率的空气噪音进行吸收。
由此，可设计多个消音子腔210中至少两个消音子腔210的容积不同，以使至少两个消音子腔210可用于对不同频率的空气噪音进行消除或弱减。例如，多个消音子腔210中的一个消音子腔210的容积小于另一个消音子腔210的容积，即将一个消音子腔210的宽度和/或长度设置为小于另一个消音子腔210的宽度和/或长度，从而使得至少两个消音子腔210用于消除不同频率的空气噪音。
根据本申请实施例的消音器20，通过在消音器20内设置多个消音子腔210，且多个消音子腔210中至少两个消音子腔210的容积不同，以使该消音器20能够实现对不同频率的空气噪音进行吸收，利于提升消音器20的宽频消音效果，且消音器20内多个消音子腔210相互拼接组合，利于提高消音器20的空间紧凑性和结构整体性，以实现消音器20的小型化设计，在目标频段较低或空间尺寸有限的情况下，能够提高消音器20的空间利用率，保证良好的声学性能和消声效果。
在一些实施例中，消音子腔210的宽度与消音子腔210的长度的比值小于0.5。由此，使得消音子腔210的宽度较小，从而便于多个消音子腔210均布置于消音器20内，利于多个消音子腔210进行合理布局，以提高消音器20的空间紧凑性和结构整体性，以实现消音器20的小型化设计，在目标频段较低或空间尺寸有限的情况下，能够提高消音器20的空间利用率。
同时，消音子腔210的长度较长，以保证消音子腔210具有足够的容积，从而保证消音子腔210具有良好的声学性能和消声效果。
在一些实施例中，如图3和图4所示，多个消音子腔210中的至少两个消音子腔210的长度不同。
由此，利于在消音器20内部实现多个消音子腔210的容积不同，以使多个消音子腔210对应不同目标消音频率，同时提高消音器20内的空间利用率，实现结构的空间紧凑性和结构整体性，利于实现消音器20的小型化设计。
进一步地，两个相邻且长度不同的消音子腔210在远离消音入口的一端形成有阶梯结构。
由此，便于提高消音器20内的空间利用率，实现结构的空间紧凑性和结构整体性，利于实现消音器20的小型化设计。
例如，如图3和图4所示，位于外侧的消音子腔210的下端朝向相邻的消音子腔210形成阶梯结构，一方面，便于充分利用容积较小的消音子腔210的下部的安装空间，另一方面，使得位于外侧的消音子腔210的容积大于与之相邻的消音子腔210的容积，进而利于提高消音器20内的空间利用率，实现结构的空间紧凑性和结构整体性，利于实现消音器20的小型化设计。
在一些实施例中，任意相邻的两个消音子腔210的长度不同。
由此，利于在消音器20内部实现多个消音子腔210的容积不同，以使多个消音子腔210对应不同目标消音频率，同时提高消音器20内的空间利用率，实现结构的空间紧凑性和结构整体性，利于实现消音器20的小型化设计。
例如，任意相邻的两个消音子腔210的宽度相同、长度不同，从而使得任意相邻的两个消音子腔210的容积不同，进而使得得任意相邻的两个消音子腔210对应不同目标消音频率，从而使得任意相邻的两个消音子腔210用于消除不同频率的噪声。
在一些实施例中，多个消音子腔210中，位于外侧的消音子腔210的长度大于位于中部的消音子腔210的长度。由此，利于最外侧的两个消音子腔210中的一个的下端朝向位于中部的两个消音子腔210延伸以形成阶梯结构，从而提高消音器20内的空间利用率，提高消音器20内部的空间紧凑性和结构整体性。
例如，如图3所示，两个消音器20中的一个消音器20，在消音器20的长度方向(上下方向)上，位于最外侧的两个消音子腔210的长度相同且均大于位于中部的两个消音子腔210的长度，其中，位于中部的两个消音子腔210的长度不同，且位于最外侧的两个消音子腔210中的一个的下端朝向位于中部的两个消音子腔210延伸以形成阶梯结构。
以及，如图4所示，两个消音器20中的一个消音器20，在消音器20的长度方向(上下方向)上，位于最外侧的两个消音子腔210的长度相同且均大于位于中部的两个消音子腔210的长度，其中，位于中部的两个消音子腔210的长度不同，且位于最外侧的两个消音子腔210的下端分别朝向相邻的位于中部的对应的消音子腔210延伸以形成阶梯结构。
由此，通过设计多个消音子腔210的长度不同，使得多个消音子腔210对应不同目标 消音频率，同时，通过设计阶梯结构，利于提高消音器20内的空间利用率，提高消音器20内部的空间紧凑性和结构整体性，利于实现消音器20的小型化设计。
在一些实施例中，消音插管22偏心布置于消音子腔210内，以使得各消音插管22的中心线位于同一平面A，各消音入口集中于消音器20的同一端，从而利于消音器20的安装，保证各消音子腔210的消音效果。
换言之，消音插管22的中心与对应的消音子腔210的中心不重合，如将消音插管22在对应的消音子腔210内设置于偏下的区域内，或者将消音插管22在对应的消音子腔210内设置于偏上的区域内。
示例性地，将消音插管22在对应的消音子腔210内设置于偏上的区域内，由此，使得各消音插管22的中心线位于消音器20上端的同一平面A，消音入口集中于导风腔11的上端，从而利于消音器20的安装，保证各消音子腔210的消音效果。
其中，需要说明的是，每个消音器20的多个消音插管22均由两个等高隔板30和消音器20的内侧壁限定出，相比于现有的消音器的插管为单独的结构，便于降低消音插管22的加工难度。
由此，一方面，便于将消音插管22的部分侧壁与消音器20的侧壁一体化设置，即消音插管22与消音子腔210的侧壁一体化设计，相比于现有的内插管与消音腔21单独设计的方案，利于降低加工难度，便于生产。另一方面，这一设计可在一定背腔截面尺寸下最大化消音器20内的消音插管22的截面尺寸，降低消音器20在目标频率下消声作用区域的声波通过率，同时简化消音插管22结构和消音器20加工。
在一些实施例中，多个消音子腔210内的消音插管22的轴线位于同一平面内，以便于使得各消音插管22的中心线位于同一平面A，各消音入口集中于消音器20同一端，利于保证其消音效果，同时，便于降低消音插管22的布局难度，方便消音器20安装。
例如图1所示，A表示多个消音子腔210的消音插管22的轴线所在的同一平面。由此，各消音入口集中于消音器20的同一端，利于保证其消音效果。
在一些实施例中，至少两个消音插管22伸至对应的消音子腔210内的长度不同。即至少两个消音插管22的长度不同。
需要说明的是，在消音子腔210的容积相同的情况下，消音插管22的长度不同使得对应的消音子腔210能够对不同频率的空气噪音实现吸收或降噪。
而本申请中，通过设计多个消音插管22的长度不同，且多个消音插管22分别对应的消音子腔210的容积不同，以使多个消音子腔210分别具有不同的消音效果，如可对应不同频率的空气噪音，以最大化地丰富消音器20的消音频率范围，从而使得多个消音子腔210能够对不同频率的空气噪音进行吸收。
需要说明的是，消音器20的多个消音子腔210的容积和对应的消音插管22长度适于根据其目标频率进行定量设计，每个消音器20的多个消音子腔210组合构成规则的长方体，以形成消音器20外形，各消音插管22的长度不同，但大致相当，使得消音器20在其消声作用平面处的区域可于各消音子腔210设计的目标频率附近一定带宽(约15Hz)范围内实现低于0.1的声波通过率，从而达到消声目的。
在一些实施例中，如图3和图4所示，消音插管22的宽度与消音子腔210的宽度相同。由此，可在一定的消音器20的截面尺寸下最大化消音插管22的截面尺寸，降低消音器20在目标频率下消声作用区域的声波通过率，同时简化消音插管22结构以及消音器20加工。
在一些实施例中，多个消音子腔210中的至少两个的内腔形状不同。
如将多个消音子腔210中的两个或三个或者更多个设置为形状不同，以使多个消音子腔210中的两个、三个或者更多个分别具有不同的消音效果，如可对应不同频率的空气噪音。且在具体设计时，可将多个消音子腔210构造为矩形腔、球形腔或者多个矩形腔拼接的不规则腔体，以保证各消音子腔210在其目标频率的消音效果，同时，使得消音器20具有规则的外形，以便于安装。
其中，可将多个消音子腔210的形状均设置为不同，以最大化地丰富多个消音器20的消音频率范围，如多个消音子腔210的长度不同，以在相邻两个多个消音子腔210的连接处形成阶梯结构。如图3和图4中所示，每个消音器20均形成有四个消音子腔210，且四个消音子腔210的形状大小均不同，尤其如图3和图4所示四个消音子腔210并排分布于消音器20内且在同一截面方向上形成的截面形状不同，从而使得四个消音子腔210能够对不同频率的空气噪音进行吸收，优化宽频带消音性能。
在一些实施例中，多个消音子腔210中的至少两个消音子腔210的布置方式不同。
由此，使得多个消音子腔210均能够对不同频率的噪声进行吸收或降噪，以最大化地丰富消音器20的消音频率范围，利于提高消音器20的消音性能。
本申请还提出了一种消音器组件100。
根据本申请实施例的消音器组件100，包括波导管10和上述实施例中任一项的消音器20，波导管10具有导风腔11，消音器20安装于波导管10，且消音入口与导风腔11连通。
由此，通过在波导管10上设置消音器20，且使得消音入口连通于导风腔11，从而在导风腔11内通过声波时，利用消音器20对波导管10内传播的噪音起到消音和降噪的作用。
例如：消音器组件100应用于冰箱上，冰箱的壳体形成有通风口，波导管10的一端与壳体相连以使导风腔11与通风口对接。其中，波导管10具有与导风腔11连通的进口和出口，以在波导管10与壳体固定后，导风腔11的进口与冰箱的通风口连通，进而使得冰箱内的噪音可从通风口进入到导风腔11内，进而经过消音器20的消音作用后，减少噪音传 出至冰箱外部，利于优化冰箱的降噪性能，同时通过波导管10满足通风口处的通风要求，且利用消音器20实现降噪功能。
其中，消音器20安装于波导管10，如消音器20构造为卡接固定于波导管10的外周壁，或者采用焊接、螺接等方式进行固定，结构简单，安装方便，其中，消音器20均为亥姆霍兹共鸣器。
示例性地，在波导管10的外周壁设有连通孔，消音器20安装于波导管10的连通孔处，以使消音插管22通过连通孔与导风腔11连通，进而通过消音腔21内空气与导风腔内特定频率声波的共振作用，实现对导风腔11内传播的噪音的消音作用。
根据本申请实施例的消音器组件100，其消音器20通过设置多个消音子腔210，且多个消音子腔210中至少两个消音子腔210的容积不同，以使该消音器20能够实现对不同频率的空气噪音进行吸收，利于提升消音器20的宽频消音效果，且消音器20内多个消音子腔210相互拼接组合，利于提高消音器20的空间紧凑性和结构整体性，以实现消音器20的小型化设计，在目标频段较低或空间尺寸有限的情况下，能够提高消音器20的空间利用率，保证良好的声学性能和消声效果。
在一些实施例中，波导管10具有矩形横截面，消音器20设有两个，两个消音器20分别安装于波导管10的相对的两侧。
换言之，波导管10具有四边形横截面，以使波导管10整体构造为方形管。两个消音器20位于波导管10的相对的两个侧面，如图1所示，两个消音器20在波导管10的两侧正对，以使两个消音器20在波导管10上分别安装。由此，使得消音器组件100的结构设计紧凑且外形规则，适于在有限空间下安装以及不同通风量下模块化组合使用，即在有限空间尺寸下，通过本申请中的消音器组件100具有良好的吸声降噪性能。
在另一些实施例中，波导管10构造为具有多边形横截面，如波导管10具有三边形横截面、四边形横截面，或者具有更多边形的横截面，同时在实际设计时，也可将消音器20构造为方形结构，利于实现消音器20与波导管10的贴合安装，使得结构安装更加紧凑。
由此，使得波导管10外周壁具有平滑的侧面，进而在将消音器组件100安装于波导管10时，安装更加方便，且利于实现消音器20在波导管10上的组合安装，使得消音器组件100的结构设计紧凑且外形规则，适于在有限空间下安装以及不同通风量下模块化组合使用，即在有限空间尺寸下，通过本申请中的消音器组件100具有良好的吸声降噪性能。
进一步地，两个消音器20的多个消音子腔210的布置方式不同。
在一些实施例中，多个消音子腔210的分布方向垂直于导风腔11的导风方向。
如在垂直于导风方向的方向(消音器20的宽度方向)上，多个消音子腔210依次分布，以使噪音在导风腔11内传播时，声波于同一横截面处受到各消音子腔210的共振作用，从 而在保证消音器20宽频消音效果的基础上，使其便于安装。
在另一些实施例中，多个消音子腔210的延伸方向可与前述实施例中的延伸方向垂直，即多个消音子腔210的延伸方向为图3中的左右方向，且关于阶梯结构以及消音插管22等均与前述实施例相同，在此不再赘述。
下面结合附图1-4描述本申请的一个具体实施例，其中，消音器20设有两个，每个消音器20均设有四个消音子腔210，即共有八个消音子腔210，且分别为：第一消音子腔211、第二消音子腔212、第三消音子腔213、第四消音子腔214、第五消音子腔215、第六消音子腔216、第七消音子腔217和第八消音子腔218，每个消音子腔210均对应设置有消音插管22。
两个消音器20中的一个，如图3所示，消音器20内设置有第一消音子腔211、第四消音子腔214、第六消音子腔216和第八消音子腔218，两个消音器20中的另一个，如图4所示，消音器20内设置有第二消音子腔212、第三消音子腔213、第五消音子腔215和第七消音子腔217，其中，由第一消音子腔211到第八消音子腔218，其对应的容积逐渐减小，且由第一消音子腔211到第八消音子腔218，其对应的目标噪声频率分别为305Hz、335Hz、305Hz、400Hz、430Hz、465Hz、495Hz、555Hz和595Hz。
其中，容积较小的消音子腔210的长度较短，呈规则的长方体形，容积较大的消音子腔210的长度较长，且在长度方向末端呈阶梯状，占据容积较小的消音子腔210的下方空间且增大自身容积，多个消音子腔210组合成规则的长方体外形，以构造成组合消音器20。
由此，将多个单个的消音器20集成于同一消音器20上，可满足不同目标频率的消音器20的消音腔21的要求，保证良好的声学性能和消声效果；同时提高组合消音器20的空间利用率，保证组合结构的空间紧凑性和结构整体性。
进一步地，消音插管22的偏心设计，利于使得各目标频率对应的消音子腔210的消音插管22均偏心内插于其消音子腔210的同一端，且各消音插管22轴线位于同一消声作用平面，以便于消音器20的安装和多个消音器20的组合使用。
相比于现有技术，本申请的消音器组件100至少具有以下优势：
1、在同一消音器20内根据不同目标频率设计消音子腔210具有不同的容积，利于保证消音器20具有良好的声学性能和消声效果，同时利于保证多个消音子腔210的组合结构的空间紧凑性和结构整体性。
2、可于目标频段较低或空间尺寸有限的情况下，通过多个消音子腔210组合的设计，提高消音器20的空间利用率，保证良好的声学性能和消声效果。
3、可于尺寸有限的消声作用平面布置更多不同目标频率的消音子腔210，提高消音器20的宽频带消声效果。
4、可使不同目标频率的消音子腔210的消音插管22位于同一消声作用平面，方便消音器20安装和多个消音器20组合使用。
5、可在一定的消音器20的截面尺寸下，最大化消音插管22的截面尺寸，降低消音器20在目标频率下消声作用区域的声波通过率。
6、可增强消音器20的消音插管22与对应的消音子腔210的结构整体性，简化消音器20结构，方便加工制作。
本申请还提出了一种冰箱。
根据本申请实施例的冰箱，设置有上述任一项实施例的消音器组件100。
需要说明的是，当消音器组件100安装于冰箱上时，波导管10可构造为冷媒管路、或者风道、或者压机仓等产生噪声的位置，即直接将消音器组件100安装于冷媒管路、或者风道、或者压机舱，以实现其消音作用。
或者可在需要消音的通风口位置，将波导管10直接与通风口连通，以在实现其通风的同时起到消音的作用，即在实现消音的同时，不影响其通风和散热性能。
根据本申请实施例的冰箱，其消音器组件100的消音器20内设置多个消音子腔210，且多个消音子腔210中至少两个消音子腔210的容积不同，以使该消音器20能够实现对不同频率的空气噪音进行吸收，利于提升消音器20的宽频消音效果，且消音器20内多个消音子腔210相互拼接组合，利于提高消音器20的空间紧凑性和结构整体性，以实现消音器20的小型化设计，在目标频段较低或空间尺寸有限的情况下，能够提高消音器20的空间利用率，保证良好的声学性能和消声效果。
