应该理解，本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。
本实用新型一实施例提供一种消音装置1和冰箱，该冰箱通过在压机仓2内设置消音装置1，使得冰箱对外发出的噪音减弱，保护了冰箱周围的环境。
本实施例提供的冰箱，包括压机仓2，如图1或图4所示，压机仓2中设置上述的消音装置1，压机仓2通过通孔12与外界连通，压机仓2包括壳体21以及由壳体21围出的 腔体20，压机仓2还包括壳体21上开设的通风口22，用于通风散热。
为清楚地表达本实施例中所描述的位置与方向，在本实施例中，定义冰箱门的正对方向为前，反方向定义为后，冰箱竖直放置在地面上，参重力方向定义为下，反方向定义为上，在冰箱的前方，冰箱的两侧分别为冰箱的左侧和右侧，本实施例的压机仓2设置于冰箱的下后方，压机仓2的左右两侧设置连通外界的通风口22，左侧和右侧是相对的，也就是说，如果从压机仓2正后方来看，左和右也可以互换。
实施例1
具体地，本实施例提供的一种消音装置1，如图1～图7所示，包括消音本体11，消音本体11上开设通孔12，消音本体11包括围出通孔12的孔壁13、以及形成于消音本体11内部的消音腔14，孔壁13表面设置连通消音腔14的开口15。
声音在通过消音装置1时经过通孔12，在通孔12的孔壁13上设置开口15，至少部分声音经过开口15，进而进入到开孔内的消音腔14中，消音腔14具有一定的深度，声音进入开口15后再在消音腔14内部传播，从而使声音经过通孔12时的传播路径增长，通过设置该声学超材料，实现了降噪效果。
进一步地，沿孔壁13表面一周设置多个开口15，如图2所示，至少两个开口15内部的消音腔14的容积不同。消音腔14的容积能够决定该消音腔14所能消除的声音的频率段，即不同的消音腔14具有不同的消音频率段，因此，可以通过调整不同消音腔14的容积，声音进入不同开口15内，将不同频率的噪音消除，让该消音装置1具有较宽的消音频率。
以及，孔壁13包括多个侧壁，每个侧壁上设置多个面积不同的开口15，在开口15大小不同的情况下，进入不同开口15的声波进入开口15后传递的方向和路径均发生变化，实现了对声音中向各个方向传递的不同波长的声音进行降噪，且对不同频率波长的声音降噪，在经过了多个不同的开口15后，实现其对更宽频率的声音的降噪。
开口15可以设置为长方形，若干侧壁上的开口15的长度方向沿通孔12的进出方向布设，若干侧壁上的开口15的宽度方向沿通孔12的进出方向布设，如图3所示，这样对不同方向的波，分别在横着的方向和竖着的方向容纳吸声，降噪效果进一步提高。
进一步地，压机仓2上的通风口22与消音装置1的通孔12相对设置，穿过通风口22的气流也会全部穿过通孔12，压机仓2的壳体21包括设置于腔体20两侧的侧壁，通风口22包括分别形成于其中一侧的侧壁上的进风口、以及形成于另一侧壁的出风口，消音本体11与侧壁相抵，使得进出压机仓2的气流，都会经过消音装置1，从而保障了进风和出风的位置都能降噪，而在压机仓2的其他位置都是不与外界连通的，也就是说，压机仓2仅通过通风口22与外界连通，而经过通风口22时声音会经过通孔12，再进入到消音腔14内进行降噪，所有进出压机仓2的气流均会被降噪。
更进一步地，消音本体11设置于腔体20内部，如图1所示，这样设置使压机仓2外部可以与现有的冰箱一样进行填充发泡料以及设置外箱壳，当然，如果压机仓2内部空间 限制，在其内部设置消音本体11困难时，也可以设置在压机仓2外部，如图所示，进风口及与其相对的通孔12形状相同且重合设置，和/或出风口及与其相对的通孔12形状相同且重合设置。在进风和出风方向，都可以将通孔12与通风口22重合，以使得通风量最大化。
在实施例2中，消音腔14设置为迷宫形，如图5～6所示，这样声音进入消音腔14后进一步地向内部传播，很大一部分无法再反射出，使得声音进入消音腔14内后不会再离开消音装置1散发到外界中，进一步地提高了其消音效果。
在实施例3中，通风口22处形成一个圆形的孔，消音本体11也设置为圆形，嵌在在通风口22内侧一圈，如图7所示，这样既不占用压机仓2内部的空间，也不占用其外部的空间，消音本体11的外侧的圆周面抵接在通风口22处，这样经过通风口22的气流，都会经过通孔12，通风口22的尺寸设计得更大，消音本体11装入通风口22处后，通孔12的孔径为原来未设置消音装置1时的通风口22的孔径。
进一步地，还包括设置于压机仓2内的风扇4，风扇4的进风方向朝向进风口，风扇4的出风方向朝向出风口。风扇4起到强制压机仓2内气流流动的作用，将进风口处的风吹向出风口。
以及，在实施例4中，压机仓2内设置风扇4，该风扇4可以是轴流风机，压机仓2内设置上述的消音装置1，消音装置1围出通风口22，风扇4的进风口和/或出风口连通通风口22。
具体地，如图8所示，消音装置1形成风机支架的结构，围出一个方型的框体，将消音装置1形成该框架结构支撑风扇4，风扇4固定安装于风机支架内，这样风机引导气流流过该通风口22时，气流即进入了消音装置1的消音腔14内，消音装置1对经过风扇4的所有气流均实现降噪效果，降低了风扇4的噪音。
另外，在实施例5中，如图9-10所示，风扇4设置为贯流风机，贯流风机的出风口朝向外界，消音装置1设置于出风口处，这样风机吹向外界的气流都经过了消音装置1的降噪，减少了压机仓2对外发出的噪音，贯流风机的出风口为条形状，消音装置1也设置为两个相对设置的条形状，对称设置于出风口的两侧。
与现有技术相比，本实施例具有以下有益效果：
冰箱的压机仓2内的噪音通过该消音装置1的通孔12时，声音传递通过开口15进入到消音腔14内，延长了声音的传播路径，减弱了声音的能量，使继续向外发散的声音降低，从而降低了冰箱产生的噪音，且不影响压机仓2内正常的排风和散热，在保障冰箱正常运行的前提下实现了很好的降噪效果。
应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施方式中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
上文所列出的一系列的详细说明仅仅是针对本实用新型的可行性实施方式的具体说明，它们并非用以限制本实用新型的保护范围，凡未脱离本实用新型技艺精神所作的等效实施方式或变更均应包含在本实用新型的保护范围之内。
