根据下文结合附图对本发明具体实施例的详细描述，本领域技术人员将会更加明了本发明的上述以及其他目的、优点和特征。
附图说明
后文将参照附图以示例性而非限制性的方式详细描述本发明的一些具体实施例。附图中相同的附图标记标示了相同或类似的部件或部分。本领域技术人员应该理解，这些附图未必是按比例绘制的。附图中：

图6是根据本发明一个实施例的冰箱的送风风机的局部示意图。
具体实施方式
本实施例提供了一种冰箱，下面参照图1至图6来描述本发明实施例的冰箱。为了便于描述，说明书中提及的“上”、“下”、“前”、“后”、“顶”、“底”、“横向”等方位均按照冰箱正常工作状态下的空间位置关系进行限定。横向即是指与冰箱的宽度方向平行的方向。
冰箱包括位于最下方的储物内胆130、蒸发器101和送风风机103，储物内胆130内限定有冷却室和位于冷却室上方的储物间室，蒸发器101设置于冷却室内，配置为冷却流经其的空气，以形成向储物间室供应的冷却空气，送风风机103则配置为促使空气在冷却室与储物间室之间循环流动，送风风机103包括机壳和设置于机壳内的叶轮1033，送风风道141在气流方向上位于送风风机103的下游，分别与冷却室和储物间室连通，配置为将冷却空气输送至储物间室内，从而可向储物间室持续地供应冷却空气，以保证储物间室的温度能够达到相应的目标温度。
其中，储物间室与冷却室可由设置于储物内胆130的罩壳(未示出)进行隔离，也即是说，罩壳将储物内胆130限定的空间分隔为储物间室和位于储物间室下方的冷却室。
传统冰箱中，冰箱的最下方空间一般为储物空间，该储物空间所处位置较低，用户需要大幅度弯腰或蹲下才能对最下方的储物空间进行取放物品的操作，不便于用户使用，尤其不方便老人使用。并且，传统冰箱的蒸发器一般位于最下方的储物空间的后方，占用了最下方储物空间的后方区域，使得最下方储物空间的进深深度减小，再者，传统冰箱的压机舱一般位于最下方储物空间的后下方，最下方储物空间不可避免地要为压机舱让位，导致最下 方储物空间异形，进一步减小了最下方储物空间的容积，而且不便于体积较大且不易分割物品的存放。
为解决传统冰箱存在的各种问题，在本申请之前，本申请的发明人设计了一种蒸发器底置的新型冰箱，该新型冰箱与本实施例的冰箱的共同点在于，冷却室由位于最下方的储物内胆130限定，储物内胆130限定的储物间室则位于冷却室的上方。该类设计的冰箱，由于冰箱最下方的空间为冷却室，抬高了位于冷却室上方的储物间室的高度，降低用户对储物间室进行取放物品操作时的弯腰程度，提升用户的使用体验。另外，蒸发器101不再占用储物间室的后方空间，保证了储物间室的进深尺寸。而且，压机舱可位于冷却室的后下方，冷却室为压机舱让位，储物间室无需再为压机舱让位，成型为体积较大、形状规整的矩形空间，便于放置体积较大不易分割的物品，解决无法在储物间室放置较大物品的痛点。
然而，发明人此前设计的该类新型冰箱中，送风风机103与送风风道141是分体式设计，送风风机103的机壳与送风风道141通过螺钉固定，机壳与送风风道141的螺钉固定的硬接触会增加送风风机运行而带来的振动传递，导致噪音较大；而且，机壳与送风风道141需要分开制造，增加了工序复杂性，另外，安装过程中需要先将送风风道141与储物内胆130装配，确认无误后才能装配机壳，一旦送风风道141装配存在失误，会导致机壳装配不到位，影响冰箱的整机性能。
基于上述问题，本申请将送风风机103的机壳与送风风道141设计为一体化，可减缓送风风机103的振动引起的噪音传递，并方便与储物内胆130装配。
其中，机壳可设置于冷却室内并位于蒸发器101的后方，包括下盒体1032和与下盒体1032限定出容纳叶轮1033的上盖体1031。而送风风道141可设置于储物内胆130的后壁内侧，包括风道后盖板1412和位于风道后盖板1412前侧与风道后盖板1412限定出气流通道的风道前盖板1411，风道前盖板1411形成有向储物间室吹送冷却空气的出风口141a，下盒体1032与风道后盖板1412呈一体化设计，上盖体1031与风道前盖板1411呈一体化设计，如此只需两套模具即可完成机壳和送风风道141的生产，而且一体成型的下盒体1032和风道后盖板1412与一体成型的上盖体1031和风道前盖板1411之间可卡合连接，无需利用螺钉固定，减缓送风风机103的振动引起的 噪音传递。
叶轮1033等其他部件可预先安装于下盒体1032上，送风风机103与送风风道141与储物内胆130装配时，一体成型的下盒体1032和风道后盖板1412可先与储物内胆130装配，一体成型的上盖体1031和风道前盖板1411再与下盒体1032和风道后盖板1412进行卡合，易于装配到位。
为便于下盒体1032与储物内胆130的装配，本实施例对下盒体1032和储物内胆130的底壁进行改进设计，具体地，下盒体1032的横向两侧分别形成有一个安装板10321，安装板10321形成有第一螺钉孔1032b，而储物内胆130的底壁的横向两侧形成有分别与两个安装板10321对应的安装凸台130c，两个安装凸台130c形成有与两个第一螺钉孔1032b一一对应的两个第二螺钉孔(未标号)，以利用穿过第一螺钉孔1032b和对应的第二螺钉孔的螺钉将下盒体1032固定于储物内胆130上。本实施例通过在储物内胆130的底壁上设计安装凸台130c，一方面便于对下盒体1032的安装位置进行定位，一方面可增加下盒体1032安装的稳定性。
进一步地，由于安装板10321与安装凸台130c之间通过螺钉固定，为减少风机振动传递，本实施例中在安装板10321与安装凸台130c之间设置弹性件(未示出)，通过弹性件吸收风机的振动噪音，从而减缓振动噪音的传递。弹性件可为弹性海绵。
进一步地，下盒体1032的底壁内侧沿叶轮1033的周侧设置有间隔分布的多个减振垫1034，以进一步减小风机的振动噪音。
下盒体1032的底壁可形成有向上延伸的多个支柱1032d，以对上盖体1031形成支撑，避免上盖体1031因受到外力而向下凹陷。在图6所示的实施例中，支柱1032d为三个，三个支柱1032d呈三角形分布，其中两个支柱1032d位于下盒体1032的底壁临近前端位置的横向两侧，另一支柱1032d位于下盒体1032的底壁临近后端位置的横向大致中间区域，如此保证对上盖体1031的支撑强度和支撑平衡性。
在附图所示的实施例中，送风风机103为离心风机，机壳可由后至前呈向下倾斜设置，如此降低送风风机103的高度，减小对冷却室高度空间的占用，以增加冷却室上方的储物间室的容积。叶轮的旋转轴由下至上呈向前倾斜，上盖体1031的上壁面可形成有进风口1031a，以增加进风顺畅性。在可替代性实施例中，送风风机103可为轴流风机或贯流风机。
储物内胆130的底壁上表面包括位于蒸发器101下方的接水区段1312，接水区段1312由四周向中间逐渐下凹，用于接收由蒸发器101掉落的化霜水，接水区段1312的最低位置形成有排水口130e，可排出蒸发器101滴落的化霜水。排水口130e处一般连接有排水管(未示出)，排水管可延伸至压机舱的蒸发皿中，以利用压机舱的散热将水蒸发。
本实施例中，由于送风风机103位于冷却室内并处于蒸发器101的后方，送风风机103距离蒸发器101较近，如果罩壳与蒸发器101之间存在缝隙，储物间室的回风会穿过间隙进入送风风机103内，造成送风风机103的叶片结霜，蒸发器101化霜的同时，送风风机103的叶片会因化霜而导致机壳内积水，影响送风风机103的运行。为此，本实施例在下盒体1032的底壁的最低位置处形成排水孔1032c，从而可将机壳内的化霜水排出，保证送风风机103的正常运行。而且由于机壳呈向下倾斜设置，由排水孔1032c流出的化霜水会沿接水区段1312流动至排水口130e处，由排水口130e排出。
前述的储物内胆130可为冷冻内胆，相应地，储物间室可为冷冻室，而冷冻室相对于变温室、冷藏室而言温度最低，冷却室分布于冷冻室的下方，有利于保持冷冻室的最低温度。
罩壳的前壁可形成有前回风入口，冷冻室的回风可通过前回风入口进入冷却室内由蒸发器101进行重新冷却，从而向冷冻室持续供应冷却空气。
本实施例的冰箱还可包括位于冷冻内胆上方的冷藏内胆、变温内胆，冷藏内胆可位于变温内胆的上方，冷藏内胆限定有冷藏室，变温内胆内限定有变温室。相应地，冰箱还可包括变温风道和冷藏风道，变温风道用于连通变温室与冷却室，以在变温室与冷却室之间形成空气循环流道，冷藏风道用于连通冷藏室与冷却室，以在冷藏室与冷却室之间形成空气循环流道。
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。
