图1是根据本发明一个实施例的冷藏冷冻装置的示意性局部结构图，如图1所示，并参考图2至图8，本发明实施例提供了一种冷藏冷冻装置。冷藏冷冻装置包括发泡层、压缩机仓30和降噪模块40。发泡层具有用于围成压缩机仓30的发泡区域。也就是说，压缩机仓30的外侧设置有发泡结构，例如压缩机仓30的横向两侧设置有发泡结构，该发泡结构为发泡层的用于围成压缩机仓30的发泡区域。特别地，降噪模块40包括消音本体41，消音本体41具有声音进出面，消音本体41内部具有至少一个消音腔42，声音进出面上设置有至少一个连通口，每个连通口连通一个或多个消音腔42，每个消音腔42通过至少一个连通口与声音进出面的外侧连通。降噪模块40设置于发泡区域内，且每个消音腔42通过对应的连通口与压缩机仓30连通。
冷藏冷冻装置工作时，压缩机仓30内压缩机等产生的噪音，声音传递通过连通口进入到消音腔42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。而且，消音腔42的长度可使得噪声的入射声波与反射声波在消音腔42的连通口处进行叠加，幅值尽量相等，相位尽量反转180°，使得声波尽量相互抵消，达到消声或降噪目的。特别地，将降噪模块40安装于压缩机仓30周围的发泡层内，不额外占用冰箱的容积，即能够尽量小的损失冰箱的容积，且安装稳定稳固，耐冲击，满足运输试验。
在本发明的一些实施例中，如图1和图2，以及图6至图8所示，消音本体41上开设有通孔，通孔的孔壁为声音进出面，通孔的一端连通压缩机仓30；通孔的另一端与冷藏冷冻装置的外侧空间连通。将消音本体41与压缩机仓30的散热气流通道配合使用，可显著降低传出压缩机仓30的噪音。优选地，发泡区域为两个，设置于压缩机仓30的横向两侧；降噪模块40为两个，分别设置于两个发泡区域内。消音本体41采用ABS材质，即降噪模块40采用ABS材质，阻燃、安全、无异味，且具有良好的吸音降噪功能。
为了便于降噪模块40的安装，保证牢固性，如图6至图8所示，消音本体41的朝向压缩机仓30的表面上设置有至少一个第一凹槽43，且每个第一凹槽43在垂直于朝向压缩机仓30的方向的一个或多个参考方向上贯穿消音本体41。消音本体41的背离压缩机仓30的表面上设置有至少一个第二凹槽44，且每个第二凹槽44在垂直于朝向压缩机仓30的方向的一个或多个参考方向上贯穿消音本体41。
例如，第一凹槽43的数量为三个或四个，设置于消音本体41的相应表面的三个或四个角落处。进一步地，第一凹槽43可与消音本体41的两个相邻的端面贯通，
方便发泡料的流动。第二凹槽44的数量为两个、三个或四个，设置于消音本体41的相应表面的两个、三个或四个角落处。第二凹槽44可与消音本体41的两个相邻的端面贯通，方便发泡料的流动。
在本发明的一些实施例中，如图1和图2所示，冷藏冷冻装置还包括箱体，箱体具有壳体组件，壳体组件包括外壳21和设置于外壳21内侧的、用于围成压缩机仓30的压缩机仓壁22。例如，外壳21可为冷藏冷冻装置的箱体的U壳，压缩机仓壁22为压缩机仓30的侧板。U壳和侧板等构成壳体组件。
发泡区域设置于外壳21的内侧，且与外壳21接触。发泡区域设置于压缩机仓壁22的外侧，且与压缩机仓壁22接触。也就是说，发泡区域设置于外壳21和压缩机仓壁22之间，降噪模块40周围填充发泡剂，通过发泡剂将降噪模块40与冷藏冷冻装置的U壳和底钢侧板粘合，连接牢固。消音本体41的朝向压缩机仓30的表面与压缩机仓壁22接触或者间隔设置。消音本体41的背离压缩机仓30的表面与外壳21接触或者间隔设置。优选地，消音本体41与外壳21和压缩机仓壁22均间隔设置，即降噪模块40居中放置于压缩机仓30侧板与冷藏冷冻装置的箱体U壳之间，两侧均留有一定间隙用来让发泡料填充其中。
在本发明的一些实施例中，如图3至图5所示，消音本体41的朝向压缩机仓30的表面上设置有第一安装环45，第一安装环45的朝向压缩机仓30的表面上设置有环槽。压缩机仓壁22上设置有第一安装孔，第一安装孔的边缘设置有插入环槽的翻边23，第一安装孔与通孔对准。压缩机仓壁22与第一安装环45固定连接，例如通过螺钉的方式固定连接。压缩机仓壁22与第一安装环45接触的区域向远离压缩机仓的方向凹陷。环槽内处于翻边23的内侧和/或外侧设置有多个沿第一安装孔的周向方向依次间隔设置的抵接块，与翻边23接触抵靠。便于降噪模块40与压缩机仓壁22的固定连接。
在本发明的一些实施例中，消音本体41的背离压缩机仓30的表面上设置有第二安装环46，第二安装环46的背离压缩机仓30的表面上设置有环形凸条47。外壳21上设置有第二安装孔，环形凸条47插入第二安装孔，第二安装孔与通孔对准。便于降噪模块40与外壳21的固定连接。
在本发明的一些实施例中，冷藏冷冻装置还包括通风格栅，通风格栅安装于通孔的背离压缩机仓30的一端。进一步地，通风格栅处于外壳21的外侧。外壳21的外侧设置有凹陷槽，第二安装孔设置于凹陷槽的槽底壁上，通风格栅位于凹陷槽内。
为了便于通风格栅的安装和通用性要求，通风格栅通过卡接结构安装于通孔的
背离压缩机仓30的一端。卡接结构包括卡接孔条51、卡接凸块52和卡扣。卡接孔条51的两端连接于通孔的背离压缩机仓30的一端的孔边缘处，以限定出卡接孔。卡接凸块52设置于卡接孔内，且连接于通孔的背离压缩机仓30的一端的孔边缘处。卡扣连接于通风格栅的朝向压缩机仓30的表面上，插入卡接孔，且与卡接凸块52配合。降噪模块40中间设计通风格栅的安装装配接口，与现有接口一致，用于安装通风格栅，提高通用性和实用性，降低成本，可以是用于不同品类不同型号的冰箱。所述卡接孔条51的朝向所述卡接凸块52的表面倾斜设置，以形成引导所述卡扣插入的引导斜面，便于卡扣的插入。
在本发明的一些实施例中，冷凝器、散热风机和压缩机沿横向方向依次设置，同时将降噪模块40设置于压缩机仓30的横向两侧，可使一个降噪模块尽量靠近压缩机，使降噪效果达到最好，且降噪模块40设置于发泡层内，不能影响压缩机仓30内散热空气的流动，因此也不影响冷藏冷冻装置的能效、安全等性能。
在本发明的一些实施例中，消音腔42的部分或全部可呈迷宫形。噪音在通过降噪模块40时经过声音进出面，然后通过在声音进出面上的连通口进入到消音腔42中，消音腔42的部分或全部可呈迷宫形，具有一定的深度，使声音经的传播路径增长，通过设置该声学超结构，实现了降噪效果。优选地，每个连通口连通一个消音腔42，每个消音腔42通过一个连通口与声音进出面的外侧连通。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他变型或修改。
