参图1-图2所示为本发明冰箱饮水装置的自动供水系统的一较佳实施方式。本发明的冰箱饮水装置的自动供水系统包括控制单元(图未示)、水箱20、及供水管40，其中，水箱20设于冰箱门体10的内侧，供水管40穿过冰箱门体10设置，供水管40的一端连通水源，另一端连通水箱20，用于给水箱20供水。
水箱20，可拆卸地固定在冰箱门体10的内侧，当门体10处于关闭状态时，水箱20位于冰箱的制冷间室(图未示)内。具体地，水箱20包括：箱体21和遮盖箱体21的盖体(图未示)，箱体21包括侧壁211、212、213、214、底壁(未标号)及出水口216，其中，侧壁211和侧壁212相对设置，侧壁213和侧壁214相对设置，侧壁211、212、213、214和底壁共同限定有储水空间，出水口216凸设在侧壁211和底壁(未标号)的连接处。特别地，在箱体21和盖体之间设有密封圈(图未示)以加强箱体21和盖体之间的密闭性。可以理解的是，箱体21和水箱盖体22之间的密封方式并不限于此，只要其可满足水箱20的密封要求即可。
水箱20通过箱体21与门体10可拆卸地卡接。具体地，门体10的内侧设有门衬11及凸伸出门衬11的第一侧壁12和第二侧壁13，在第一侧壁12和第二侧壁13之间设有底座14，在底座14上设有连通冰箱外界的取水通道60。
在第一侧壁12和第二侧壁13上分别设有第一定位块121和第二定位块(图未示)，水箱20的两个相对的侧壁213和214上分别设有第一卡槽2131和第二卡槽(图未示)，第一卡槽2131和第二卡槽(图未示)呈U型设置，U型的开口可容纳定位块，当水箱20安装到门衬11上时，只需将第一卡槽2131卡持在第一定位块121上，第二卡槽卡持在第二定位块131上，即可将水箱20固定在门衬11的底座14上。拆卸水箱20时，只需沿着第一卡槽2131和第二卡槽2141的轴向方向将水箱20拔出即可，拆装方便。
进一步地，在门衬11的底座14上设有连通冰箱外界的取水通道60，在取水通道60中设有取水组件30，水箱20的出水口216通过螺纹与取水组件30连通且固定，用户在冰箱外即可通过取水组件30获取来自水箱20中的水。
优选地，在门衬11上靠近取水通道60处设有第一凹陷部111，第一凹陷部111呈拱形，用以避让出水口216，使得水箱20与门衬11贴合紧密，当箱体21安装到门衬11上时，出水口216的至少部分位于第一凹陷部111内。
在门体10上设有供供水管40穿过的第一开孔70，在水箱20的侧壁211上设有第二开孔2111，供水管40依次经过第一开孔70和第二开孔2111到达水箱20中，供水管40靠近 第一开孔70的一端连通水源(图未示)，靠近第二开孔2111的一端位于水箱20的箱体21中，且位于箱体21中一端上设有注水嘴41。优选地，注水嘴41到箱体21底壁的距离小于盖体到箱体底壁的距离，将注水管40及注水嘴41经由水箱20的侧壁211进入箱体21，而在现有技术中，注水管40和注水嘴41通常是经由水箱的盖体进入箱体，本发明与现有技术相比，注水管40及注水嘴41没有经由水箱的盖体进入水箱，使得本发明中水箱的盖体安装更便捷。同时，拆卸水箱20时，只需将注水嘴41拔掉，水箱20便可自由取下，便于清洗。
在此值得一提的是，注水管40上设有与控制单元(图未示)电性连接的水阀(图未示)，在箱体21靠近门衬11的内壁211上设有内盒22，在内盒22中设有感应浮子23，内盒22上设有若干供水流动的水孔221，以使得感应浮子23在内盒22中且可随水箱20中水位变化沿内盒22的高度方向上下移动，从而利用感应浮子23判断水箱20中的水位。
在门衬11上设有第二凹陷部112，其用于放置感应传感器50，第二凹陷部112的位置与水箱20安装到门衬11上时内盒22的位置对应。优选地，感应传感器50为霍尔元件或接近式感应元件，与之相应地，感应浮子为磁性浮子或接近式感应浮子。
参图3所示，感应传感器50被配置为当感应浮子23在其感测范围内时，感应传感器50反馈信号至控制单元，控制单元发出命令将水阀处于打开位置；当感应浮子23超出其感测范围内时，感应传感器50反馈信号至控制单元，控制单元发出命令将水阀处于关闭位置。具体地，将水箱20中感应浮子23所在的下限设置在感应传感器50的感应范围内，感应浮子23所在的上限则超出感应传感器50的感应范围。感应传感器50感测水箱20中的感应浮子23是否在其感测范围内，若在，延时1秒再次感测，若还在，感应传感器50反馈信号至控制单元，控制单元发出命令将水阀处于打开位置，水箱需要加水，同时感应传感器50继续感测水箱20中的感应浮子23是否在其感测范围内；若感应传感器50无法感测到感测水箱20中的感应浮子23时，延时几秒，停止注水，同时感应传感器50继续感测水箱20中的感应浮子23是否在其感测范围内。用户取水后感应传感器50可根据感应浮子23的位置再次进行动作闭环形成自动供水。
相应地，本发明还提供一种冰箱(未图示)，该冰箱通过采用上述各实施方式中介绍的冰箱饮水装置的自动供水系统，可以取得上述各实施方式中冰箱饮水装置的自动供水系统具有的有益效果，并且，由于对该冰箱的其他结构或功能并未做出改进，故在此对该冰箱的其它结构也不再赘述。
对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明。因此，无论从哪一 点来看，均应将实施例看作是示范性的，而且是非限制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，说明书的这种叙述方式仅仅是为清楚起见，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
