本公开提出了一种具有制冰机的冰箱，该制冰机所在的制冰室设于该冰箱的冷藏室中，该制冰机包括：
金属制冰格，该金属制冰格设于制冰室上部，用于供该金属制冰格中所存储的水冷冻为冰块；
储冰盒，该储冰盒设于该制冰格下方，用于存储从该制冰格中脱落的冰块；
出冰电机，该出冰电机设于制冰室下部，用于将该储冰盒中存储的冰块输出该制冰机；
制冰蒸发器，该制冰蒸发器通过贯穿制冰室室体上的装配孔的方式固定并贴附于该金属制冰格的下部以向该金属制冰格提供冷量；
隔热泡沫，该隔热泡沫用于填充该制冰蒸发器与该装配孔之间的空隙，并包裹该制冰蒸发器裸露的部分，其中，该制冰蒸发器被该隔热泡沫所包裹的部分设有圆弧结构的定位圆弧以与该隔热泡沫紧密配合。
本公开所提供的具有制冰机的冰箱，其中制冰机的制冰蒸发器被隔热泡沫所包裹，保温的同时也起着固定的作用，从而在避免制冰蒸发器表面结冰的同时提高了制冰蒸发器的装配精度；而且，该制冰蒸发器上被隔热泡沫所包裹的部分设有圆弧结构的定位圆弧，从而保证制冰蒸发器伸入制冰室长度的精准定位的同时，避免了组装和运输过程中制冰蒸发器与隔热泡沫之间的串动，进一步地提高了制冰蒸发器的装配精度。
图1示出了根据本公开一些实施例的冰箱外部的结构示意图。
参考图1所示，该实施例中，冰箱的上半部分为两门对开的冷藏室1，下半部分为冷冻室2。其中，制冰室设于冷藏室1的内部，在冷藏室1的门体表面设有冷藏室的出冰口3。该出冰口3同时也可以作为出水口，冰块或者水均可以从该出冰口3中输出冰箱外部。通过门体上设置的显示板4可以将输出冰箱的物体在整冰、碎冰以及水之间进行切换。
图2示出了根据本公开一些实施例的冰箱的冷藏室打开后的结构示意图。
参考图2所示，该实施例中，将冷藏室1的门体打开后，可以看到制冰室5设于冷藏室1的上部。其中，制冰机设于制冰室5中。
在本公开的一些实施例中，该制冰室的出冰口与该冷藏室的出冰口对接。制冰室设于冷藏室中，且制冰室的出冰口与冷藏室的出冰口对接，从而当冰块从制冰室的出冰口输出后，无需打开冷藏室的门体，冰块即可自动从冷藏室的出冰口中输出。
图3示出了根据本公开一些实施例的冰箱的制冰室内部的结构示意图。
参考图3所示，设于制冰室内部的制冰机包括金属制冰格6、储冰盒7、出冰电机8、制冰蒸发器9、隔热泡沫10以及储冰盒门面板11。
其中，金属制冰格6由金属材料制成，设于制冰室的上部，用于将其中所存储的水冷冻为冰块。
储冰盒7位于金属制冰格6下方，冰块从金属制冰格6中的脱落后并会落入并存储在该储冰盒7中。
出冰电机8设于制冰室的下部，其用于将储冰盒7中存储的冰块输出制冰机。
由于出冰电机8的装配需要占用一定空间，因此制冰蒸发器9贯穿制冰室，其中的一部分伸出制冰室。制冰蒸发器9贴附于金属制冰格6的下部，从而冰箱的压缩机工作后，温度降低的制冰蒸发器9向金属制冰格6直接传递冷量，从而使得金属制冰格6中的水能够冷冻为冰块。
在制冰蒸发器9的裸露部分包裹有隔热泡沫10，从而使得裸露的部分 不会被冰层覆盖；同时，隔热泡沫10也填充在制冰蒸发器9与所贯穿的制冰室室体上的装配孔之间的空隙，以固定制冰蒸发器9。从而避免制冰蒸发器9表面结冰的同时提高了制冰蒸发器9的装配精度。
图4示出了根据本公开一些实施例的冰箱的制冰机蒸发器与隔热泡沫的装配示意图。
参考图4所示，制冰蒸发器9上设有一段圆弧结构的定位圆弧12，发泡后得到的上隔热泡沫13以及下隔热泡沫14与该定位圆弧12相紧密配合，从而保证制冰蒸发器伸入制冰室长度的精度定位，并在扎带固定位15的作用下进一步固定。
在本公开的一些实施例中，该制冰蒸发器的表面镀镍。通过在制冰蒸发器的表面进行镀镍，避免了冰箱使用过程中制冰蒸发器的腐蚀，从而提高了制冰蒸发器的使用寿命。
在本公开的一些实施例中，该金属制冰格的下部设有安装槽，该制冰蒸发器装配在该安装槽中并贴附于该金属制冰格的下部。
具体的，金属制冰格的下部设有与制冰蒸发器形状相配合的安装槽以供制冰蒸发器装配在该安装槽中，从而制冰蒸发器贴附于金属制冰格的下部，以向金属制冰格直接提供冷量。
在本公开的一些实施例中，该制冰机还包括脱冰加热器，该脱冰加热器设于该金属制冰格的下部，用于加热该金属制冰格以使该金属制冰格中的冰块脱落。
具体的，该脱冰加热器设于金属制冰格的下部，通过脱冰加热器的加热，金属制冰格在受热后其中冷冻的冰块的表面会融化，从而冰块从金属制冰格中脱落。
在本公开的一些实施例中，该制冰机还包括制冰风机，该制冰风机设于该制冰蒸发器下方的风道，用于促进该风道内的空气流动，并将该制冰蒸发器的冷量传递至该储冰盒。
具体的，该制冰风机的工作会带动该风道中的空气流动，将制冰蒸发器 的冷量传递至储冰盒，从而使得有源源不断的充足冷量保障其中的冰块不被融化。
图5示出了根据本公开一些实施例的冰箱的制冰蒸发器与相邻组件的结构示意图。
参考图5所示，制冰蒸发器9被隔热泡沫10所包裹，且在隔热泡沫10与装配孔16的配合下，制冰蒸发器9贯穿制冰室，一部分伸出制冰室，另一部分通过装配在金属制冰格6下部的安装槽17贴附于金属制冰格6下部。
在金属制冰格6下部还设有脱冰加热器18。通过脱冰加热器18的加热，金属制冰格6在受热后其中冷冻的冰块的表面会融化，从而冰块从金属制冰格6中脱落。
在制冰蒸发器9的右下部设有制冰风机19，具体的，在制冰蒸发器9下部的风道设有制冰风机19，用于促进该风道内的空气流动。
图6示出了根据本公开一些实施例的冰箱的制冰风机的工作示意图。
参考图6所示，在制冰蒸发器9下部的风道设有制冰风机19。该制冰风机19的工作会带动该风道中的空气流动，将制冰蒸发器9的冷量传递至储冰盒7，从而使得有源源不断的充足冷量保障其中的冰块不被融化。
同时，风道内的空气流动形成如图6所示的风循环。由于风循环的发生，降低了制冰室内不同部位的温度差异，避免了间室湿热空气在制冰蒸发器9附近凝结，从而避免了该风道的阻塞。
在本公开的一些实施例中，该制冰蒸发器与该冰箱的回气管一体。通过这种结构，使得在冰箱装配环节，无需单独焊接组装制冰蒸发器，从而提高了冰箱的装配效率与装配质量。
图7示出了根据本公开一些实施例的冰箱的制冷蒸发器与回气管一体的结构示意图。参考图7所示，回气管包括冷冻蒸发器进出口接管17以及压缩机回气接口18。制冰蒸发器9与冰箱的回气管一体使得制冰蒸发器9可以直接伸入制冰室，无需在冰箱装配过程中单独焊接，提高了车间装配效率和装配质量。
在本公开的一些实施例中，该回气管的毛细管的喷射端设有过渡管，从而分级释放毛细管喷射压机差，降低毛细管内冷媒喷射造成的噪声。一般的，过渡管的长度大于120mm。
在本公开的一些实施例中，该过渡管包括一级过渡管以及二级过渡管。
在本公开的一些实施例中，该毛细管与该过渡管的焊接位置包裹有降噪胶泥。从而进一步地降低了毛细管内冷媒喷射造成的噪声。同时，降噪胶泥设置在回气管上，降噪胶泥无法与外界热湿空气接触，从而避免了降噪胶泥在恶劣环境下的脱落失效，延长了降噪胶泥的使用寿命。一般的，降噪胶泥的包裹长度为100mm。
图8示出了根据本公开一些实施例的冰箱的回气管的结构示意图。
参考图8所示，该实施回气管的毛细管23的喷射端设有过渡管24，在毛细管23与过渡管24的焊接处包裹有降噪胶泥25，从而降低冷媒喷射造成的噪声。且由于降噪胶泥25包裹在回气管上，处于冰箱发泡层内部，不与外界热湿环境接触，从而避免了降噪胶泥25在间室内有一热湿空气等原因而脱落。在装配效率上，降噪胶泥25包裹在回气管上，避免了在间室狭小空间包裹，提高了工作效率，同时也保证了降噪胶泥25的安装质量。
图9示出了根据本公开一些实施例的冰箱的过渡管的结构示意图。
参考图9所示，过渡管24与回气管的接口被降噪胶泥25所包裹。
图10示出了根据本公开一些实施例的冰箱的过渡管的结构示意图。
参考图10所示，过渡管包括一级过渡管26以及二级过渡管27，一级过渡管26与回气管的接口被降噪胶泥所包裹。
本领域技术人员在考虑说明书及实践这里公开的公开后，将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开的真正范围和精神由所附的权利要求指出。
