在一些实施例中，通过使制冰格430的底部包括固定盘440，固定盘440被配置为使制冷剂管310紧贴制冰格430的底部，由此，可以保证制冷剂管310与制冰格430有效接触，增大传热面积，使制冷剂管310产生的冷量能够最大效率地传递到制冰格430。并且，固定盘440与制冰格430之间包括通风道，风机组件420可直接吸入位于所述通风道内的冷风。

在一些实施例中，参见图6及图10，上盖板470设于制冰格430的顶部，上盖板470的顶部包括避让槽472以避让翻冰部4621。上盖板470还包括侧翼473，侧翼473由上盖板470的顶部向下延伸。在一些实施例中，侧翼473包括多个风孔471，多个风孔471被配置为使风通过，多个风孔471的尺寸可以相同或不同。在一些实施例中，如图10所示，侧翼473也可以不包括多个风孔471。
在一些实施例中，参见图6和图15，当风机组件420工作时，循环风扇422从吸风侧抽风(例如从固定盘440与制冰格430之间的通风道抽取冷风)，向出风侧吹风。
在图15中，所述出风侧为前侧即循环风扇422向前吹风。冷风向前并向下运动，流经制冰腔室130的前向角落位置以及储冰容器500后，继续流经制冰腔室130的后向角落位置，以及接水盘450与固定盘440之间的回风道，并通过固定盘440底部的回风孔441，重新被循环风扇422吸入，如此循环，风循环的路径大致如图15中的箭头所示。
制冰腔室130内的空气在上述风循环中换热，有助于使制冰腔室130内保持温度均衡的状态，利于解决因温度差而产生的结霜、冰块粘连或融化等问题。例如，整个制冰腔室130内的制冰单元400及储冰容器500所在的区域均达到温度均衡的状态。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
本领域技术人员应当理解，本公开中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与一些实施例公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
