下面详细描述本发明的实施例， 所述实施例的示例在附图中示出， 其中自始至终相 图描述的实施例是示例性的， 仅用于解释本发明， 而不能解释为对本发明的限制。
本发明将灯组件安装在抽屉门之上的上旋转门或上抽屉门下部的凹槽中，从而能够 对抽屉内的食物进行充分的照明。 如图 3所示， 为本发明实施例的一种灯组件安装示意 图， 灯组件 10和 1 1分别为上旋转门下部和上抽屉门下部的灯组件， 这样， 在下部的抽 屉拉出后， 灯组件 10和 1 1的灯光恰好可以照射到所述抽屉内， 如图 4和 5所示。 并且 在本发明中灯光从上而下直接照射到食物表面，极大地增强了取放食物的便利性。同时， 灯光不会直射入人眼， 仅会通过食物反射入人眼， 因此对人眼不会有刺眼等不良反映。
本发明克服了本领域技术人员仅将灯组件设置在水箱箱体内的技术偏见，提高了对 于抽屉式水箱的照明效果。
本发明适于带抽屉的水箱， 该水箱应具有至少一个抽屉。 在本发明的实施例中， 该 水箱可仅有一个抽屉， 也可有多个抽屉。 该抽屉包括抽屉门， 且在抽屉门之上还包括上 旋转门或上抽屉门。 该水箱照明装置包括灯组件、 开关组件和为开关组件供电的供电组 件， 以及连接在灯组件和开关组件之间的连接组件。 其中， 灯组件位于上旋转门或上抽 屉门下部的凹槽中， 且灯组件包括照明灯组和由透光材质构成的灯罩。 开关组件根据判 断所述抽屉门是否被拉开， 来控制所述灯组件的开启和关闭。
下面以图 3所示的水箱为例进行介绍，但是需要说明的是图 3所示的水箱仅是为了 清楚的目的， 在该图中所示的水箱中包括一个旋转门和两个抽屉门， 但是并不是说本发 明仅适用于图 3所示的水箱， 其他类型的水箱 （例如仅有一个旋转门和一个抽屉等）也 可应用至本发明中。 如图 3所示， 水箱包括旋转门 1、 位于旋转门 1之下的第一抽屉门 2和第二抽屉门 3 , 因此旋转门 1相对于第一抽屉门 2即为上旋转门， 第一抽屉门 2相 对于第二抽屉门 3即为上抽屉门。在旋转门 1的下部设有用于为第一抽屉照明的灯组件 10 , 在第一抽屉门 2下部设有用于为第二抽屉照明的灯组件 11。 在本发明的实施例中， 旋转门 1可为双开门的旋转门， 也可为单开门的旋转门。
在本发明的一个优选实施例中， 灯组件 10和 11具有预设的倾斜角度， 以使灯光向 所述水箱的外部斜向照射， 从而在下部抽屉拉出后提供更好的照明。
在本发明的另一个优选实施例中，灯组件 10和 1 1的灯罩外表面与凹槽的开口平齐， 从而使之不会影响外观。
另外需要说明的是， 在本发明中对于照明灯组没有限制， 既可以采用 LED灯， 也 可以釆用普通灯泡等进行照明， 因此为照明灯组的供电方式也可釆用多种， 供电组件可 以是接入水箱的强电， 也可以是经过转换的由主控板提供的弱电。 例如， 供电组件为接 入水箱的市电， 照明灯组可以采用普通灯泡， 则开关组件连接在供电组件和照明灯组之 间。 如果照明灯组为 LED 等， 则开关组件可包括检测单元和主控板。 检测单元检测抽 屉门是否被拉开， 主控板根据所述检测单元的检测结果对灯组件进行控制。 在图 3所示 的例子中， 灯组件 10和灯组件 11均由主控板所控制， 且主控板可以将供电组件的交流 电转换为直流电之后直接提供给灯组件 10和灯组件 1 1。
在本发明的一个优选实施例中， 开关组件为安装在下部抽屉之后的箱体壁板上的开 关， 在抽屉完全推入水箱后与开关接触， 当抽屉和开关接触时， 关闭灯组件。 如图 6和 7所示， 为本发明实施例的开关组件示意图， 该开关组件包括安装在箱体内側壁上的开 关 4和位于抽屉外側壁之上的开关挡块 5 , 当抽屉完全推入水箱后开关挡块 5触碰开关 4, 开关 4关闭灯组件， 当抽屉抽出后， 开关挡块 5不与开关 4接触， 则开关 4反弹回 复到初始状态， 从而控制所述灯组件开启。
在本发明实施例中， 由于灯组件所处的位置不同， 即可能处于旋转门或抽屉门的下 部， 因此本发明可采用两种安装方式， 以下对这两种安装方式分别介绍。
安装方式一， 此种安装方式针对灯组件安装在旋转门下部的情况。 由于旋转门的旋 转轴可以做成中空， 因此可以使得开关组件和灯组件之间的连接线穿过旋转门的中空旋 转轴， 从而为灯组件供电。
安装方式二， 此种安装方式针对灯组件安装在抽屉门下部的情况。 但是由于抽屉总 是需要来回抽出， 因此对开关组件和灯组件之间的连接组件要求比较高， 如果采用连接 线直接相连， 则当抽屉拉出最长时， 导线处于被拉直的最长状态， 而当抽屉被关闭时， 连接线两个端点之间的距离又被缩短了， 由于连接线自身的重力， 且抽屉与箱体之间的 间隙很小， 因此在抽屉的运动过程中连接线很可能会与其他部件接触， 从而与其他部件 发生缠绕， 导致失效。 为了解决安装方式二中存在的问题，本发明提出了多种连接在开关组件和灯组件之 间的连接组件的优选实施例， 包括：
实施例一，
在该实施例中， 可采用电磁感应的方式解决该问题。 如图 8所示， 为本发明实施例 一的上抽屉的结构图， 在该上抽屉的側壁之上具有电气盒 6。 如图所示， 该电气盒设置 在抽屉门体的后侧， 同时不会影响抽屉门体的开关。 如图 9和 10所示， 在电气盒 6中 设置有第二线圈 8和相应的处理电路 9 , 在水箱箱体内側壁之上设有第一线圈 7 , 且第 一线圏 7与第二线圏 8的位置相对应，从而可以相互感应。第一线圏 7与开关组件相连， 第二线圏 8通过相应的处理电路 9与灯组件 10相连。 第一线圏 7发射电磁能量， 第二 线圏 8感应后经过处理电路 9处理后提供给灯组件 10 , 从而达到为灯组件 10供电的目 的。 其中， 在本发明的一个实施例中， 处理电路 9包括全桥整流电路， 将交流电转换为 直流电提供给灯组件 10。由于在该实施例中第一线圈 7和第二线圏 8之间没有实物接触， 且各部件没有活动件， 因此可靠性高。
在该实施例中， 当上抽屉关闭时， 第一线圏 7和第二线圏 8对应耦合， 当上抽屉门 下部的抽屉被拉开后， 根据开关组件提供的控制信号第一线圏 7导通， 并通过感应第二 线圏 8向灯组件 10提供电能， 灯组件 10开始照明。 此时如果拉开该上抽屉， 则下方的 抽屉因为该上抽屉阻挡， 已经不适合取放食物， 显然此时不需要照明。 因此在上抽屉被 拉开时， 第一线圏 7和第二线圏 8 已经相互错位， 没有耦合， 此时灯组件 10可停止照 明。
该实施例的优点是没有运动件， 工作可靠， 缺点是电磁感应传输的电能有限， 大功 率成本较高， 但是考虑到现今 LED照明技术已经相当普及， 低功率大流明是成熟技术， 因此该缺点基本可以忽略。
在本发明中， 供电组件可为工频交流电， 也可为水箱主控板输出的直流电。
如图 1 1 所示， 为本发明一个实施例的连接组件电路图， 该实施例中以工频交流电 为输入， 通过第一全桥整流电路变换成直流电， 然后逆变转换成高频交流电流并提供给 第一线圏 7 , 第二线圏 8与第一线圈 7感应并输出高频电流， 再经过第二全桥整流电路 变换为直流电， 从而提供给灯组件 10。
如图 12所示， 为本发明另一个实施例的连接组件电路图， 该实施例以冰箱主控板 直接输出的直流电作为输入， 因此无需上述实施例中的第一全桥整流电路。 实施例二，
与实施例一不同的是， 该实施例二采用连接线的方式直接将开关组件和灯组件相互 连接， 但是为了解决上述连接线由于自身重力而引起的缠绕问题， 还需要设置一个收线 器， 该收线器可以固定在箱体之上或者固定在上抽屉之上， 连接线部分地缠绕在收线器 之上。 当上抽屉抽出或关闭时， 收线器向连接线施加预设的力以拉紧连接线， 防止该连 接线与其他部件发生缠绕。 本实施例采用机械连接的方法实现， 可通过收线器使导线长 度根据抽屉的运动自由变换长度， 因此该实施例可以实现大功率连接， 同时不受抽屉状 态的影响， 随时都可以供电。
如图 13 所示， 为本发明实施例二的收线器结构图。 该收线器包括固定在箱体或上 抽屉之上的固定部 14 , 和套接在固定部 14之上的旋转部 12 , 旋转部 12可自由转动， 且连接线 20部分地缠绕在旋转部 12之上， 连接线 20的一端与灯组件相连， 另一端与 开关组件相连。 该收线器还包括卷簧 13 , 卷簧 13的一端与旋转部 12相连， 另一端与固 定部 14相连，旋转部 12转动时压缩卷簧 13以使卷簧 13产生驱动旋转部 12的驱动力。 例如， 当上抽屉被拉出后， 连接线 20的一端随着上抽屉门一起运动， 连接线 20带动旋 转部 12转动， 旋转部 12旋转使卷簧 13压缩收紧， 此时由于卷簧 13的弹性， 使得上抽 屉门和收线器之间的连接线呈直线状。 当上抽屉门关闭时， 抽屉门与收线器之间的距离 缩短， 此时由于卷簧 13 的弹力使得旋转部旋转， 从而将多余的连接线缠绕在旋转部之 上， 从而也能够保持抽屉门和收线器之间的连接线呈直线状。 图 14和图 15分别示出了 收线器的卷簧 13和旋转部 12的俯视图。从图 14中可以看出卷簧 13的一端与固定部 14 相连接， 另一端与旋转部 12相连接。 从图 15中可以看出固定部 14具有中心孔， 连接 线 20的一部分缠绕在旋转部 12上， 一端拉出与抽屉的门体之上的至少一个电气组件相 连，连接线 20的另一端穿过固定部 14的中心孔，与;水箱箱体内部的控制组件和 /或供电 组件相连。 其中， 连接线可为电源线或者也可以是提供电信号的控制线。 实施例三，
在该实施例中本发明还可通过第一端子和第二端子的接触，从而为抽屉门体上的电 气组件供电或提供电信号， 并且在本发明中没有运动件， 因此可靠性高。 例如在本发明 的一个实施例中， 第一端子和第二端子可为插座或插头， 从而实现为抽屉门体上的电气 组件进行供电。 在本实施例中， 第一端子和第二端子可分别为插座和插头。 具体的说， 当第一端子为插座时， 第二端子为能插入该插座的插头； 当第二端子为插座时， 第一端 子为能插入该插座的插头。
如图 16所示， 为本发明实施例三的上抽屉的结构图， 在该上抽屉的外侧壁之上具 有插头 15。 如图 17和 18所示， 该连接组件包括位于水箱箱体内侧壁之上的插座 16 , 且插座 16与开关组件相连， 以及位于上抽屉侧壁的插头 15 , 插头 15与插座 16的位置 相对， 且在上抽屉关闭时插头 15插入插座 16 , 其中， 插头 15与灯组件 17相连。
在该实施例中， 插座 16与开关组件相连， 如果开关组件包括主控板的话， 则插座
16与主控板相连， 有主控板上的直流电直接为灯组件 17供电。
对于目前的水箱来说， 由于抽屉的导轨安装已经非常精细， 因此插头 15和插座 16 之间不会出现无法插入等问题， 可靠性高。
尽管已经示出和描述了本发明的实施例， 对于本领域的普通技术人员而言， 可以理 解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、 修改、 替换 和变型， 本发明的范围由所附权利要求及其等同限定。
