冰箱及其发光搁物架
本申请要求了申请日为2017年12月25日，申请号为201711424112.X，发明名称为“冰箱及其发光搁物架”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及一种冰箱及其发光搁物架，属于制冷设备领域。
背景技术
现有冰箱为了方便用户取放冰箱内食物，一般会在冰箱内部设置照明设备。目前的冰箱一般都是在搁物架或箱体上直接悬挂或安装照明灯来对冰箱间室进行照明。但是，这种照明方式，在用户把食品放在搁物架后，特别是在冰箱内部食物较多的情况下，食品容易遮挡住照明灯的光线，影响用户使用。
另外，使用普通照明设备的冰箱，一般都是靠近照明设备的位置光线强，刺激用户视觉，给用户造成不适；而远离照明设备的位置光线弱，用户无法看清冰箱内部的食物摆放情况，因此冰箱内部光线均匀度差，视觉效果不佳，影响用户体验。随着生活质量的提高，人们对冰箱照明灯的要求也不再仅仅满足于简单的照明，而是逐步地要求有更好的视觉效果和照明效果。
近年来，一些生产厂家制作出发光搁物架来迎合市场需求，发光搁物架包括搁板和设置于搁板一侧的照明装置，照明装置向搁板发射照明光线，光线通过搁板上下表面所贴附的导光膜而进行漫反射或折射，从而均匀地照向箱体内部。但是，这样的发光搁物架还存在很多的缺陷，不能根据需要针对箱体内部的盲区进行有针对性的照明，而且有的照明装置采用线缆供电的方式，存在安全风险。
有鉴于此，有必要提供一种新的冰箱的发光搁物架以解决上述问题。
发明内容
本发明的目的在于提供一种新的冰箱及其发光搁物架，其能够提升照明效果、提高冰箱内的照明能效，避免箱体内部光线差、视觉效果不佳的问题。

作为本发明进一步改进的技术方案，所述夹角为20～70°。
作为本发明进一步改进的技术方案，所述发光搁物架还包括用于对所述搁板提供支撑的支架，所述支架中形成有收容槽，所述发光灯带设置于所述收容槽中。
作为本发明进一步改进的技术方案，所述支架包括位于所述搁板的上表面和/或下表面的饰条，所述饰条由透明材料制成。
作为本发明进一步改进的技术方案，所述发光搁物架还包括无线供电装置，所述无线供电装置包括发射器和接收器，所述发射器与外界电源连接，所述接收器与所述发光灯带电性连接，所述发射器以无线方式将能量传递给所述接收器，以便为所述发光灯带供电。
作为本发明进一步改进的技术方案，所述接收器设置于所述收容槽中。
作为本发明进一步改进的技术方案，所述搁板的表面和/或内部设有光学微结构，以使进入所述搁板内的光发生折射或漫反射，从而在所述发光搁物架的周围空间实现照明。
作为本发明进一步改进的技术方案，所述光学微结构包括在搁板的表面和/或内部形成的形状不规则的多面体凹陷。
作为本发明进一步改进的技术方案，所述光学微结构包括在搁板的内部设置的气泡或反光物质。

本文使用的例如“上”、“上方”、“下”、“下方”等表示空间相对位置的术语是出于便于说明 的目的来描述如附图中所示的一个单元或特征相对于另一个单元或特征的关系。空间相对位置的术语可以旨在包括设备在使用或工作中除了图中所示方位以外的不同方位。例如，如果将图中的设备翻转，则被描述为位于其他单元或特征“下方”或“之下”的单元将位于其他单元或特征“上方”。因此，示例性术语“下方”可以囊括上方和下方这两种方位。设备可以以其他方式被定向(旋转90度或其他朝向)，并相应地解释本文使用的与空间相关的描述语。并且，应当理解的是尽管术语第一、第二等在本文中可以被用于描述各种元件或结构，但是这些被描述对象不应受到这些术语的限制。这些术语仅用于将这些描述对象彼此区分开。
如图1所示，本发明优选的一种冰箱，包括箱体1和门体(图中未示出)，箱体1内设有多个制冷间室。在本实施例中，箱体1自上而下分别是冷藏室10、变温室11和冷冻室12，其中，冷藏室10中设有一个或多个发光搁物架2。当然，在变化的实施方式中，冷藏室10、冷冻室12以及变温室11可以采用其他的排布设计。另外，冷冻室12或变温室11中也可以根据需要设置一个或多个发光搁物架2。
在图1-图3所示的优选实施方式中，箱体1左右两侧的侧壁设置有数组安装部，发光搁物架2通过卡接或搭接的方式活动地连接于安装部上。发光搁物架2包括搁板20，搁板20由透明材料制成，其上表面形成发光搁物架2的载物平面，用于放置物品。搁板20一般设置为具有一定厚度的玻璃板或人造水晶板。
发光搁物架2还包括照明设备，照明设备包括发光体，在本优选实施方式中，发光体构造为发光灯带21，发光灯带21是将多个灯珠组装在带状的柔性线路板或PCB硬板上。发光灯带21内的多个灯珠沿其长度方向间隔设置，优选地，发光灯带21内设有5-100个灯珠，这5-100个灯珠在发光灯带21中均匀地布置。发光灯带21外套设有透明的密封套(图中未示出)以防水。在本实施例中，发光灯带21中的灯珠设置为LED灯，LED灯的发光波长为435～450mm，位于此波段的光包括蓝光，蓝光能够有效地杀灭发光搁物架2上的细菌，起到净化冰箱内部环境的作用。当然，发光体也可以构造为其他的形状，另外，发光体也可以是白炽灯或发光彩带等其他照明灯。
发光灯带21设置于搁板20的一侧边缘，用于照亮所述搁板20和其临近区域，在通电状态下，发光灯带21所发出的光从搁板20一侧向箱体1内部扩散。在本发明的优选实施方式中，发光灯带21与搁板20倾斜设置。本发明提供了发光灯带21的两个实施方式，其中第一实施例使得发光灯带21的照射范围较广，便于实现箱体1内的整体照明；第二实施例则是针对箱体1内抽屉101得不到有效照明的现状，专为搁板20底部的抽屉101实现照明的方案。以下分别针对第一实施例和第二实施例进行具体阐述。
参见图4所示，为本发明的第一实施例，在本实施例中，发光灯带21具有安装平面，多个 LED灯珠沿垂直于所述安装平面的方向布置，发光灯带21相对搁板20倾斜放置使得所述安装平面与搁板20的载物平面形成夹角，使得发光灯带21发出的光部分进入搁板20内部，部分越过搁板20进入发光搁物架2的周围空间即箱体1内部。发光灯带21与搁板20倾斜设置，使得LED灯珠的光线倾斜地射入搁板20内部，使得光线更易穿透搁板20而照亮箱体1空间，避免光线仅在搁板20内部传播而导致光线被搁物架2上所放置的物品遮挡的问题。优选地，夹角的角度范围为20～70°。
搁板20沿水平方向由箱体1左侧向右侧延伸，在图示的实施方式中，LED灯珠倾斜地朝向搁板20的上表面延伸，使得发光灯带21的安装平面与搁板20的载物平面形成夹角，该夹角为60°。换言之，发光灯带21的安装平面与搁板20的延伸方向形成钝角，该钝角的补角为60°。如此，LED灯珠的光线有一小部分直接越过搁板20的下表面照亮搁板20的底部空间，一部分进入搁板20内部；通过搁板20内光学结构的设置，光线经过折射或漫反射而使隔板的上下表面发光；另有一部分光线越过搁板20的上表面而直接进入搁物架2的上部空间，从而实现搁物架2自身及其周围空间的照明。
当然，当使LED灯珠倾斜地朝向搁板20的下表面放置，即使得发光灯带21的安装平面与搁物架2的载物平面形成20～70°的锐角，也同样能够实现搁物架2及其周围空间的照明。
参见图5的第二实施例，在本实施例中，发光灯带21与搁板20倾斜设置，发光灯带21的安装平面与搁板20的载物平面形成60°的夹角以照亮所述搁板20的下部空间。当LED灯珠倾斜地朝向搁板20的下表面放置，并与搁板20的延伸线形成夹角时，发光灯带21的照明光线部分进入搁板20内部，部分越过搁板20的下表面而进入搁板20下部的空间，这使得没有单独设置照明结构的抽屉101得到了充分的照明，解决了长期以来抽屉101内部光线不足的问题。
继续结合图2和图3所示，搁物架2还包括支架22，支架22用于提供对搁板20的支撑。在将搁物架2安装到冰箱箱体1的过程中，支架22与箱体1左右两侧的安装部活动地连接。当然，搁板20的前后两侧边也可以设置支架22。在本实施方式中，支架22设有用于固定搁板20侧边的饰条221，饰条221还可对搁板20和支架22的连接部位进行装饰，饰条221一般由柔性材料制成以提供缓振作用。
所述支架22中形成有收容槽220，所述发光灯带21设置于所述收容槽220中，使得发光灯带21能够固定于搁板20的一侧边缘，以对搁板20进行照明。具体地，发光灯带21如前所述倾斜地固定于该收容槽220中。在本实施例中，搁板20侧边与支架22的接触部位都设置有饰条221，即搁板20的上下表面都设置有饰条221，饰条221由透明材料制成，使得当发光灯带21的倾斜角度较大而使光线部分进入饰条221时，这部分光线能够穿透饰条221而进入箱体1的内 部空间，避免光能的损失。当然，在其他的实施方式中，支架22只设置位于搁板20的上表面或下表面的饰条221。
在本发明的优选实施方式中，所述搁板20的表面和/或内部设有光学微结构，以使进入所述搁板20内的光发生折射或漫反射，从而在所述发光搁物架2的周围空间实现照明。这里的微结构是指能够使光从其所在的位置射出的那些微小的结构。在本发明中，微结构可以用印刷、激光雕刻或者贴膜等方式来实现，只要其能够使得其所在位置处的光学性质发生改变从而导致光从该位置射出即可。而且，微结构的设计由光学工程师设计，其形状、大小及深度等参数依据工艺而定义。
这样，从发光灯带21中发出的光在搁板20内部传输，经过数次反射和折射，然后从搁板20的微结构所在位置射出。以激光加工为例，激光的能量在玻璃表面聚焦从而产生微炸裂，形成形状不规则的多面体凹陷，其在不同方向的良好平面反光性使得以该工艺制作的搁板20具有良好的导光性；同样通过工艺参数调节，激光加工还可以聚焦在搁板20内部实现非表面的微爆炸，即激光内雕，此情况下即不损伤表面，又同时实现导光效果。并且，因为这些“微炸裂”的尺寸相对于玻璃板而言几乎可以忽略不计，故加工几乎不影响有承重要求的搁板20的机械性能。
可以使用激光内雕实现微结构(即前述的激光加工形成的多面体凹陷)。同样也可以在搁板20生产中通过在相应位置加入气泡或反光物质来达到同样效果。在后一种情形中，加入的气泡或反光物质即是相应的微结构。
通过搁板20内部微结构的设置，进入搁板20内部的光线能够通过折射或漫反射而从搁板20的上表面和/或下表面射出，从而照亮搁板20及其上部和/或下部空间，取得更好的照明效果。
参见图3-图5所示，照明设备还包括为发光体提供电源的无线供电装置23，在本优选实施方式中，供电装置采用无线供电方式。无线供电装置23包括发射器230和接收器231，所述发射器230与外界电源连接，所述接收器231与所述发光灯带21电性连接，所述发射器230以无线方式将能量传递给所述接收器231，以便为所述发光灯带21供电。
在本实施例中，接收器231设置于支架22内，具体地，接收器231设置于收容槽220下方的接收槽222中，接收器231与发光灯带21电性连接，用于向发光灯带21供电。发射器230设置于箱体1中，优选地，发射器230邻近箱体1的安装部设置，在本实施例中，发射器230被设置于箱体1的内胆中。
优选地，发射器230和所述接收器231之间的前后可移动距离L≤2mm，所述发射器230和所述接收器231之间的左右可移动距离W≤5mm，所述发射器230和所述接收器231之间的上下可移动距离H≤3mm，当发射器230和接收器231的距离在基准距离的基础上处于上述可移动距 离范围时无线供电装置23的传输功率达到最佳，发射端的功耗损失最低，因此转换成的热量也最低，显著地改善了无线供电装置23发热严重而影响制冷效果的问题。
发射器230包括发射线圈、电源电路、高频振荡电路以及高频功率放大电路。利用冰箱本身的直流电压，该高频振荡电路负责产生高频交变电流(一般为20K至200KHz的高频电流)，而高频功率放大电路则把由高频振荡电路产生的高频电流进行放大，然后将其以电磁能量的形式由发射线圈送出。接收器231包括接收线圈和LED整流桥，该接收线圈靠近发射线圈。这样，当发射线圈中流过高频交变电流时，因为电磁感应的缘故，就可以在接收线圈中产生感应电流，从而，可以为发光体提供电能。
由于发射器230的发射线圈和接收器231的接收线圈是相互分离的，为增强他们之间的电磁耦合，将这些线圈各自装设在罐型磁芯上，且两个罐型磁芯相互靠近而使得磁力线更为闭合，以提高能量传输效率。
发光体通过无线供电装置23进行供电，其优点在于可省下许多繁琐的电缆布局。当冰箱的箱门被打开时，箱体1内的发射器230发出信号，搁物架2中的接收器231接受到信号后，产生电力并驱动发光体发亮，部分光线射进搁物架2的搁板20内，通过搁板20上下表面及其内部的微结构，使光线均匀照射到箱体1内部，不会产生照明盲区。另有部分光线进入透明的饰条221，产生折射而照射到搁板20的上部空间或下部空间，实现箱体1内部的有效照明。
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，各实施方式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。
上文所列出的一系列的详细说明仅仅是针对本发明的可行性实施方式的具体说明，它们并非用以限制本发明的保护范围，凡未脱离本发明技艺精神所作的等效实施方式或变更均应包含在本发明的保护范围之内。
