具体实施方式
本实施例提供了一种冰箱，储液包设置于冷却室，冰箱的发泡层和壳体可以阻断液体制冷剂流动的声音传播，尤其是发泡层具有良好的隔音效果。储液包与蒸发器连接且储液包的中心线与水平线的夹角为1°至89°，可以使冷却室内部结构紧凑，避免占用过多空间。图1是根据本发明一个实施例的冰箱100的正面结构示意图，图2是根据本发明一个实施例的冰箱100的侧面结构示意图，图3是根据本发明一个实施例的冰箱100中蒸发器21和储液包80的连接结构示意图，图4是根据本发明一个实施例的冰箱100中储液包80的中心线与水平线夹角的示意图，图5是根据本发明另一个实施例的冰箱100中储液包80的中心线与水平线夹角的示意图。如图1至图5所示，本实施例的冰箱100一般性地可以包括：箱体10、门体20、蒸发器21以及储液包80。
其中，箱体10，其内部限定有冷却室11和至少一个储物空间，冷却室11设置于箱体10的底部且处于储物空间的正下方。如图1和图2所示，本实施例的冰箱100可以包括由上至下设置的两个储物空间：第一空间131和第二空间132。其中第一空间131和第二空间132按照用途不同可以配置为冷藏空间、冷冻空间、变温空间或者保鲜空间。各个储物空间可以由分割板分割为多个储物区域，利用搁物架或者抽屉储存物品。
门体20设置于箱体10的前表面，以可操作地开闭储物空间。门体20与储物空间对应设置，即每一个储物空间都对应有一个或多个门体20。如图2所示，门体20可以枢转地设置于箱体10的前表面。在其他一些实施例中，门体20还可以是抽屉式开启，抽屉的底部可以设置有抽屉滑轨，以保证抽屉开启关闭过程中效果轻柔，减少噪音。
蒸发器21，整体呈扁平立方体状横置于冷却室11，且配置成向储物空间提供冷量。蒸发器21整体呈扁平立方体状横置于冷却室11，即蒸发器21的长、宽面平行于水平面，厚度面垂直于水平面放置。蒸发器21向各种类型的储物空间提供的冷量不同，使得各种类型的储物空间内的温度也不相同。例如冷藏空间内的温度一般处于2℃至10℃之间，优先为4℃至7℃。冷冻空间内的温度范围一般处于-22℃至-14℃。不同种类的物品的最佳存储 温度并不相同，进而适宜存放的储物空间也并不相同。例如果蔬类食物适宜存放于冷藏空间或者保鲜空间，而肉类食物适宜存放于冷冻空间。
在一种具体地实施例中，本实施例的冰箱100的储物空间为多个，包括冷藏空间和至少一个冷冻空间。如图1和图2所示，箱体10可以包括：冷藏内胆72和冷冻内胆71。其中，冷冻内胆71，其内部限定有冷却室11和位于冷却室11正上方的至少一个冷冻空间。冷藏内胆72，设置于冷冻内胆71正上方，其内部限定有冷藏空间。具体地，本实施例的冷藏内胆72的内部限定有第一空间131，且可以设置为冷藏空间，冷冻内胆71的内部限定有第二空间132和冷却室11，且第二空间132可以设置为冷冻空间。也就是说，本实施例的冰箱100的第二空间132邻接设置于冷却室11上方，而第一空间131间隔设置于冷却室11上方。
此外，箱体10还可以包括：壳体60和发泡层73。其中，壳体60设置于冷冻内胆71和冷藏内胆72的外部。发泡层73设置于壳体60与冷藏内胆72和冷冻内胆71之间，以隔绝冰箱100外部的热量。
储液包80设置于冷却室11且与蒸发器21连接。具体地，储液包80的一端与蒸发器21连接，另一端与压缩机连接，气、液混合的制冷剂由蒸发器21流出后经过储液包80流入压缩机。储液包80一方面可以使制冷剂气液分离，防止压缩机发生液击；另一方面可以储存一定量的液体制冷剂，并根据环境温度调节制冷剂量，以使冰箱100在不同环境温度下都能获得较好的制冷效果。储液包80设置于冷却室11，冰箱100的发泡层73和壳体60可以阻断液体制冷剂流动的声音传播，尤其是发泡层73具有良好的隔音效果，有效降低噪音，提升用户的使用体验。
如图4和图5所示，储液包80的中心线与水平线的夹角θ为1°至89°，即储液包80不垂直于水平线设置。需要说明的是，储液包80的中心线指的是液体制冷剂流入、流出储液包80的方向上的中心线。具体地，图4示出的储液包80由下至上逐渐远离蒸发器21，而图5示出的储液包80由下至上逐渐靠近蒸发器21。储液包80与蒸发器21连接且储液包80的中心线与水平线的夹角为1°至89°，避免储液包80垂直于水平线需要增大冷却室11的纵向高度，可以使冷却室11内部结构紧凑，避免占用过多空间。
如图1和图2所示，冰箱100还可以包括：送风风道31，设置于冷藏内胆72和冷冻内胆71的后壁内侧，其底端具有连通冷却室11的送风入口312， 且对应冷藏空间和冷冻空间分别设置有送风出口311，以将蒸发器21提供的冷量传输至储物空间。由于送风出口311位于每个储物空间的后侧，各个储物空间的冷量由后侧向前侧传递。
在一种优选的实施例中，如图2所示，冰箱100还可以包括：制冷风机22，设置于蒸发器21后侧，且制冷风机22的出风方向可以正对着送风入口312，以使得蒸发器21产生的冷量顺利进入送风风道31。送风风道31中还可以设置有风门313，风门313受控地开闭以调节进入冷藏空间的冷量。
图6是根据本发明一个实施例的冰箱100中储液包80的位置示意图，图7是根据本发明另一个实施例的冰箱100中储液包80的位置示意图，图8是根据本发明另一个实施例的冰箱100中储液包80的位置示意图，图9是根据本发明另一个实施例的冰箱100中储液包80的位置示意图，图10是根据本发明另一个实施例的冰箱100中储液包80的位置示意图，图11是根据本发明另一个实施例的冰箱100中储液包80的位置示意图。
如图6所示，储液包80可以设置于制冷风机22、蒸发器21和冷冻内胆71右侧围成的空间内。如图7所示，储液包80还可以设置于制冷风机22、蒸发器21和冷冻内胆71左侧围成的空间内。如图8所示，储液包80还可以设置于蒸发器21和冷冻内胆71右侧之间。如图9所示，储液包80还可以设置于蒸发器21和冷冻内胆71左侧之间。如图10和图11所示，储液包80还可以设置于蒸发器21和制冷风机22之间。具体地，图10示出的储液包80设置于蒸发器21和制冷风机22之间偏右的位置；图11示出的储液包80设置于蒸发器21和制冷风机22之间偏左的位置。储液包80在冷却室11中按照上述任一实施例的位置进行设置，均可以充分利用冷却室11中的空余空间，使冷却室11内部结构紧凑，而不会占用冰箱100的额外空间；并且保证液体制冷剂流动时产生的噪声被发泡层73和壳体60阻断，提升用户的使用体验。
图12是根据本发明一个实施例的冰箱100的局部结构分解示意图。如图3和图12所示，蒸发器21可以包括：蒸发器本体210、上盖板214以及下盖板215。其中蒸发器本体210可以包括：多个平行设置的翅片211和穿设于翅片211的盘管213，即本实施例的蒸发器本体210为翅片式蒸发器。上盖板214设置于蒸发器本体210顶部；下盖板215设置于蒸发器本体210底部。
如图4、图5和图12所示，每个翅片211的相应位置均设置有缺口212，相应位置的多个缺口212形成有沿蒸发器21横向延伸的通道。冰箱100还可以包括：加热丝90，嵌设于通道中，以对蒸发器21进行化霜。如图12所示，加热丝90可以弯折地嵌设于通道中，以对蒸发器21进行化霜。并且，加热丝90可以为铝管加热丝，金属铝可以有效增强加热丝90的导热效果，进而增强蒸发器21的化霜效果，避免蒸发器21结霜影响其正常工作，提高蒸发器21的工作可靠性。
在一种优选的实施例中，翅片211的上端和下端均设置有多个通道，且加热丝90一体式地弯折嵌设于翅片211的上端和下端的通道中。也就是说，加热丝90的其中一个接线端可以位于翅片211上端，沿着翅片211上端的通道弯折设置后沿着翅片211下端的通道弯折设置，加热丝90的另一个接线端最后位于翅片211下端。两个接线端与冰箱100内部的接线端子连接，并通过接线端子进一步连接至冰箱100的主控板，以对加热丝90的工作状态进行控制。加热丝90一体式地设置于蒸发器本体210的上端和下端，对蒸发器本体210上端和下端直接进行加热，提高化霜效率，进而提高蒸发器21的工作可靠性。
如图12所示，上盖板214四角设置有第一固定孔216，蒸发器本体210顶部四角设置有位置对应的第二固定孔217；下盖板215四角设置有第三固定孔218，蒸发器本体210底部四角设置有位置对应的第四固定孔(图中未示出)。蒸发器21还可以包括固定件(图中未示出)，配置成：穿过对准的第一固定孔216和第二固定孔217，以将上盖板214和蒸发器本体210固定；穿过对准的第三固定孔218和第四固定孔，以将下盖板215和蒸发器本体210固定。具体地，固定件可以是螺钉、铆钉或扎带等。
在一种优选的实施例中，第一固定孔216和第三固定孔218为腰形孔；第二固定孔217和第四固定孔为圆形孔。上述各固定孔的具体形状设置，可以保证上盖板214和下盖板215与蒸发器本体210固定之后，彼此之间紧密接触而不存在间隙，避免冷冻空间的回风不经过蒸发器21换热就直接吹向制冷风机22，导致制冷风机22结霜，有效保证制冷风机22的工作可靠性，进而提升冰箱100的整体制冷能力。此外，在蒸发器本体210的顶部和底部分别设置上盖板214和下盖板215，简化蒸发器21的整体结构，有效降低生产成本。还需要说明的是，上盖板214和下盖板215均是与嵌设有加热丝90 的蒸发器本体210进行固定。因此上盖板214和下盖板215还可以避免加热丝90翘起，保证加热丝90平整嵌设于翅片211的通道中。
如图1和图2所示，其中冷冻内胆71的底壁作为冷却室11的底壁可以形成有接水盘40，以承接蒸发器21产生的冷凝水。在一种优选的实施例中，如图2所示，冷却室11的前段底壁和后段底壁均为沿彼此方向倾斜向下的斜面。冷却室11的前段底壁和后段底壁与水平面均具有一定夹角，可以使得蒸发器21产生的冷凝水顺利进入接水盘40，并可以保证全部排出，有效保证蒸发器21的工作可靠性。
冷却室11的前段底壁和后段底壁的交接处设置有排水口41，排水口41位于蒸发器21的下方。且前段底壁的斜度大于后段底壁的斜度，以使排水口41在水平方向上靠近蒸发器21的前端。可以使得外部空气通过排水口41进入冷却室11后先经过蒸发器21，而不会直接在制冷风机22上形成结霜、结冰等不良现象。
如图2所示，箱体10内部还限定有压缩机仓12，压缩机仓12设置于箱体10的底部且位于冷却室11的后方。在压缩机仓12中可以设置有冷凝器、散热风机和压缩机，上述各部件由于设置于压缩机仓12内部并未在图中示出。在一种具体的实施例中，冰箱100还可以包括：蒸发皿50，设置于冷凝器的下方，以利用冷凝器的热量使蒸发皿50中的水分蒸发，并通过散热风机将水分带走以进行散热。
如图2所示，本实施例的冰箱100还可以包括：排水管42，其一端连接接水盘40的排水口41，其另一端连通至蒸发皿50，以将接水盘40中的冷凝水传输至蒸发皿50。具体地，排水管42倾斜放置，且其连接排水口41的一端高于其另一端，排水管42与水平面的夹角大于等于预设角度。排水管42倾斜的角度与接水盘40的斜面角度配合，使得接水盘40中的冷凝水可以顺利排出。
如图1和图2所示，冰箱100还可以包括：回风风道32，设置于冷藏内胆72和冷冻内胆71的任一侧壁上，且其上端设置有连通冷藏空间的回风入口321，其下端设置有连通冷却室11的回风出口323，以实现冷藏空间向冷却室11回风。具体地，回风入口321设置于冷藏内胆72的侧壁前部，回风出口323设置于冷冻内胆71同一侧的侧壁前部，并且，回风出口323设置于冷却室11处的冷冻内胆71侧壁上。回风入口321和回风出口323设置于 冷藏内胆72和冷冻内胆71的侧壁前部，可以使冷藏空间内部的冷量由后向前对冷藏空间充分降温后，通过回风风道32返回至冷却室11。在一种优选的实施例中，回风风道32可以设置有两条，并可以对称设置于冷藏内胆72和冷冻内胆71的两个侧壁上。
冰箱100还可以包括：蒸发器盖板111，罩设于蒸发器21上方，并作为顶壁与冷冻内胆71共同限定出冷却室11。在一种优选的实施例中，蒸发器盖板111的前端设置有与冷冻空间连通的冷冻回风口112，以实现冷冻空间向冷却室11回风。具体地，冷冻回风口112可以为百叶窗形。本实施例的第二空间132作为冷冻空间，邻接设置于冷却室11的上方，可以快速地通过冷冻回风口112实现向冷却室11回风。
本实施例的冰箱100，包括：箱体，其内部限定有冷却室11和至少一个储物空间，冷却室11设置于箱体的底部且处于储物空间的正下方；门体20，设置于箱体的前表面，以可操作地开闭储物空间；蒸发器21，其整体呈扁平立方体状横置于冷却室11，且配置成向储物空间提供冷量，以及储液包80，设置于冷却室11且与蒸发器21连接，储液包80的中心线与水平线的夹角为1°至89°。储液包80设置于冷却室11，冰箱100的发泡层73和壳体60可以阻断液体制冷剂流动的声音传播，尤其是发泡层73具有良好的隔音效果。储液包80与蒸发器21连接且储液包80的中心线与水平线的夹角为1°至89°，可以使冷却室11内部结构紧凑，避免占用过多空间。
进一步地，本实施例的冰箱100，蒸发器21包括：蒸发器本体210、上盖板214以及下盖板215，其中蒸发器本体210包括：多个平行设置的翅片211和穿设于翅片211的盘管213，上盖板214设置于蒸发器本体210顶部；下盖板215设置于蒸发器本体210底部。上盖板214四角设置有第一固定孔216，蒸发器本体210顶部四角设置有位置对应的第二固定孔217；下盖板215四角设置有第三固定孔218，蒸发器本体210底部四角设置有位置对应的第四固定孔。蒸发器21还包括固定件，配置成：穿过对准的第一固定孔216和第二固定孔217，以将上盖板214和蒸发器本体210固定；穿过对准的第三固定孔218和第四固定孔，以将下盖板215和蒸发器本体210固定。第一固定孔216和第三固定孔218为腰形孔；第二固定孔217和第四固定孔为圆形孔，保证上盖板214和下盖板215与蒸发器本体210固定之后，彼此之间不存在间隙，避免冷冻空间的回风不经过蒸发器21换热就直接吹向制 冷风机22，导致制冷风机22结霜，有效保证制冷风机22的工作可靠性，进而提升冰箱100的整体制冷能力。此外，在蒸发器本体210的顶部和底部分别设置上盖板214和下盖板215，简化蒸发器21的整体结构，有效降低生产成本。
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。
