技术领域
本发明涉及冰箱制冰技术领域，特别涉及一种制冰机、冰箱。
背景技术
现有冰箱制冰主要有两种脱冰方式，通过扭转冰格脱冰或者通过在冰格处设置加热器加热脱冰，前一种对冰格的材质有特定要求，导致冰格传热效率低，制冰、脱冰速度较慢，影响制冰速度。后一种需要在冰格处设置加热器，会对接近冰格的冷气造成阻碍，影响制冰效率；同时加热器只能实现对冰格的局部加热，加热不均匀，脱冰速度慢；而将加热器均匀分布在冰格内或冰格表面则会影响冰格的传热效率，制冰效率低。

具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，除非另有说明，“以上”的范围包括本数，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”、“前端”、“后端”、“头部”、“尾部”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本发明中的具体含义。
实施例一：
参见图2所示，本发明提供了一种制冰机，包括：冰格13、制冰室12和加热室11，所述冰格13能在所述制冰室12与加热室11之间切换以实现制冰与脱冰。通过切换冰格13的位置，可以使冰格13直接置于制冰室12或加热室11内，冰格13在制冰室12内吸收冷量实现制冰，然后切换到加热室11内吸收热量实现脱冰；利用加热室11内的零度以上的气体对冰格13进行加热，冰格13上无需设置加热器，因此可将冰格13尽可能做得薄一些，方便冷量或热量的快速传递，制冰、脱冰速度快，制冰效率高。
具体的，如图3所示，所述加热室11与制冰室12通过隔板21隔离，所述隔板21上设有供所述冰格13通过的通道，在所述通道处，所述冰格13与隔板21之间设有密封单元211以保持所述加热室11与制冰室12的相互隔离。并各需要通过通道才能在加热室11与制冰室12之间切换，但加热室11与制冰室12又会在通道处形成气体交换，为避免这一现象发生，在冰格13与隔板21之间设置了密封单元211以实现两个强势的隔离，减少气体交换；比如在冰格13两侧设置密封圈等，至少在冰格13处于固定状态时能实现隔离。
进一步的，所述通道具有可开闭的封挡单元，所述封挡单元用于在所述冰格13移动至所述制冰室12内时将冰格13与加热室11隔离。附图未示出，制冰时冰格13需要吸收冷量，若通道未封挡，加热室11内的热气仍能与冰格13接触，造成冷量浪费，影响制冰效率；因此在通道处设置封挡单元，当冰格13处于制冰室12内时封挡单元关闭，将冰格13封挡在制冰室12内，使冰格13与加热室11隔离，避免冰格13在制冰过程中吸收热量，提高制冰效率。当需要移动冰格13时，封挡单元开启，方便冰格13通过。冰格13处于加热室11内是，若封挡单元能关闭则关闭，若封挡单元无法关闭，则通过密封单元211保持加热室11与制冰室12之间的隔离效果。
具体的，所述冰格13通过转动单元安装在所述通道内。即通过转动单元带动冰格13旋转，实现冰格13在加热室11与制冰室12之间的切换。比如利用电机驱动转轴带动冰格13旋转，冰格13转至加热室11内吸收热量脱冰，冰格13转至制冰室12内吸收冷量制冰，冰格13位置切换灵活可控，且结构简单，制造成本低。对于这种结构，隔板21应尽可能做薄一些，或者隔板21在通道处设置薄一些，以增大冰格13在制冰室12或加加热室11内的换热面积。
优选的，如图2和3所示，所述冰格13截面为半圆形，所述转动单元的转动轴与所述半圆形冰格13的中心线重合。即从垂直冰格13旋转中心的方向看过去，冰格13截面为半圆形，冰格13可以是整体呈半球形的结构，或者是半圆槽；这种结构使得冰格13与通道之间的间隙保持均匀，方便密封单元211的设置，确保隔离效果。
优选的，所述制冰室12的壁面均设有隔热层、或均由隔热材料制成。即围成制冰室12的壁面均设有隔热层、或均由隔热材料制成，以保证制冰室12与外界的隔热效果，减少冷量损耗；降低整个制冰机对周围环境的影响。
优选的，所述制冰室12与加热室11的壁面均设有隔热层、或均由隔热材料制成。即围成制冰室12与加热室11的壁面均设有隔热层、或均由隔热材料制成，以保证制冰室12与外界的隔热效果，减少制冰室12冷量、加热室11热量的损耗；降低整个制冰机对周围环境的影响。
进一步的，所述加热室11内设有风扇111。风扇111可以增大加热室11内气体的流速，增强换热效率；同时风扇111的设置使得吹向冰格13的气流方向可控制，使热风均匀吹向冰格13表面，在提高换热效率的同时，使冰格13各处受热更加均匀，避免因冰块14局部集中受热而导致冰块14过度消融，保证制冰量。
优选的，所述加热室11位于所述制冰室12上方，制出的冰块14存储在所述制冰室12内。制冰室12兼做储冰盒，或者在制冰室12内增设储冰盒，冰格13在加热室11内受热后，冰块14可直接落入制冰室12存储起来；进水口设置在加热室11内，进水口处于零度遇上的环境中，不会发生堵塞，因此无需在进水口处设置加热模块，降低了制造成本，同时能保证制冰过程的顺利进行。
本实施例在脱冰过程中，损耗的能量只有电机带动冰格13转动，以及风扇111运转产生的能量，较现有技术给冰格加热消耗的能量要少很多；在不影响制冰效率的前提下，在脱冰的过程中使用的能量更少，更节能。
实施例二：
如图1至3所示，本实施例提供了一种冰箱，包括门体22，所述门体22上设有实施例一所述的制冰机，所述制冰机的制冰室12设有出冰口121，所述出冰口121与所述门体22上的分配器连通。即将实施例一所述的制冰机整体设置在冰箱门体22上，为保证美观性，制冰机一般都会装在门体22内侧，制冰室12的出冰口121与门体22上的分配器连通，用户可在不打开门体22的状态下取用冰块14。无论制冰机安装在冷冻室3门上还是冷藏室2门上，制冰室12都通过管路与冷冻室3连通或者与冷 冻室3内的蒸发器处连通以实现引入、引出冷空气的目的。制冰室12可通过开设在其与冰箱箱胆交界面处的接口引入、引出冷空气，门体22打开后冷空气通道断开，门体22关闭后冷空气通道接通。整个制冰机为封闭架构，不会影响冰箱储藏室内的温度和储藏效果；同时实现了一定的隔音效果，提高用户体验。
当在制冰室12内设有储冰盒时，储冰盒底部也应对应开设出冰口121。储冰盒的存在可以方便冷空气通过，冷空气不经过冰块14就能直接与冰格13进行热交换，保证制冰效果；储冰盒能实现阻挡，减小冷空气与冰块14的接触面积，降低冰块14发生粘结的几率，提高用户体验。
进一步的，所述制冰室12底部设有推冰单元122。推冰单元122的设置是为了将冰块14推向出冰口121，实现分批次取冰。当然，若有需要，也可增设碎冰单元，或将推冰单元122替换为碎冰单元。
实施例三：
如图4所示，本实施例提供了一种冰箱，包括冷藏室2和冷冻室3，所述冷藏室2内设有实施例一所述的制冰机，所述制冰机的制冰室12通过管路与所述冷冻室3或蒸发器冷气出口连通。即将制冰机设置在冷藏室2内，制冰室12通过管路时刻处于与冷冻室3或蒸发器冷气出口连通的状态，开关门不影响制冰过程。这种结构中，制冰室12应设置为可开启的状态，方便用户取冰。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
