Description

具有可重量检测的搁架组件的冰箱 技术领域
本发明整体上涉及冰箱，更具体地，涉及具有用于检测搁架组件上物品重量特征的冰箱。
背景技术
诸如冰箱和食品柜之类的储藏箱一般提供用于收容多种物品或物体的封闭室。例如，冰箱一般包括具有制冷间室的箱体。用户可以将食品或物体放置在制冷间室内，以防止此类食品腐烂。由此，可以延长易腐物品或物体的使用时间。
随着时间的推移，冰箱的制冷间室内会堆积大量或许多储藏的物品(例如，食品)。随着所储藏物品的堆积，冰箱的用户可能难以识别位于冰箱内的物品。另外，用户可能还难以确定冰箱内某些物品的数量。当多个用户在没有与其他用户沟通的情况下向一个普通的冰箱中添加或从中取出物品时，尤其如此。因此，用户可能会不小心购买不需要的物品或未能购买快用完的物品。举例来说，诸如液体或农产品之类的物品储藏在用户难以看到内部的容器内。这些物品可能是不定期使用和分部分使用，使得容器的所有内容物只会在多次使用后才被清空。附加地或可替代地，一些用户可能不知道某些物品已被清理或被食用。结果，用户可能无法确定容器何时近空以及何时需要更换。
一些现有电器已经尝试通过要求用户手动输入正在储藏的每一个物品来解决这些问题。其他电器已采用各种方法(诸如天平)来评估或猜测正在储藏的物品的数量或标识。尽管如此，这些尝试还不够麻烦或不够昂贵。举例来说，典型的天平需要将各种电线布线到电器的特定搁架或区域。如果需要多个天平或重量感测区域，显然需要附加的电线和连接。结果，与负载重量(尤其是跨越多个搁架)检测相关联的复杂性和成本非常巨大。此外，即使一旦检测到重量，常规系统仍需要用户手动输入或了解正在称重的物品，这可能非常困难或非常麻烦。
相应地，具有用于辅助用户跟踪冰箱的制冷间室的内容物的特征的冰箱将会非常有益。特别地，具有用于辅助用户准确跟踪冰箱的制冷间室的内容物的数量或体积而不会使组件或操作明显变复杂(例如，跨多个搁架)的冰箱将会非常有益。

具体实施方式
现在将详细参考本发明的实施例，在附图中说明其一个或多个示例。每个示例均用于对本发明进行解释说明，而不是对其进行限制。实际上，对本领域技术人员而言显而易见的是，在不脱离本发明的范围的情况下，可以对本发明进行各种修改和变型。举例来说，作为一个实施例的一部分说明或描述的特征可以和另一实施例一起使用来产生又一实施例。因此，本发明旨在涵盖落入所附权利要求及其等同物的范围内的此类修改和变型。
如本文所用，术语“或”一般旨在表示包括在内(即“A或B”旨在表示“A或B或两者”)。术语“第一”，“第二”和“第三”可互换使用，以将一个部件与另一个部件区分开，并非旨在指示各个部件的位置或重要性。
现在转到附图，图1提供了根据本公开的示例性实施例的冰箱100的主视图，其中冰箱100的冷藏门128显示为处于关闭位置。图2提供了冰箱100的主视图，其中冷藏门128显示为处于打开位置，以展示哪些100的食物保鲜室122。
冰箱100包括沿竖直方向V在顶部101和底部102之间延伸的壳体或箱体120。箱体120限定出用于收容食品进行储藏的制冷间室。特别地，箱体120限定出位于箱体120的顶部101或其附近的食物保鲜室122，以及布置在箱体120底部102或其附近的冷冻室124。如此，冰箱100一般被称为底置式冰箱。然而，应当认识到，本发明的益处适用于其他类型和风格的储藏箱，例如顶置式冰箱、对开门冰箱或非制冷食品储藏箱。因此，本文阐述的说明书仅出于说明的目的，并非旨在任何方面限制任何特定的储藏箱或冷藏室配置。
冷藏门128可旋转地铰接到箱体120的边缘，用于可选择地进入食物保鲜室122。另外，冷冻门130布置在冷藏门128下方，用于可选择地进入冷冻室124。冷冻门130联接到冷冻抽屉142(未示出)，该冷冻抽屉142可滑动地安装在冷冻室124内。如上所讨论的，冷藏门128和冷冻门130在图1中显示为处于关闭配置，并且冷藏门128在图2中显示为处于打开位置。
现在转到图2，如本领域技术人员将理解的，各种储藏部件安装在食物保鲜室 122内，以便将食品储藏在其中。特别地，储藏部件包括安装在食物保鲜室122内的盒体140、抽屉142和搁架144。盒体140、抽屉142和搁架144配置成用于收容所储藏的物品(例如，饮料或固体食品)，并且可以辅助整理此类食品。作为示例，抽屉142可以收容新鲜食品(例如，蔬菜、水果或奶酪)，并且可以延长此类新鲜食品的使用寿命。如下文将更详细描述的，一个或多个搁架144或抽屉142可以包括在安装到食物保鲜室124内胆的搁架组件200中，或者作为一部分包括在搁架组件200中。
冰箱100还包括用于辅助用户识别位于食物保鲜室122或冷冻室124内的食品的特征。用户可以利用此类特征例如查看食物保鲜室122或冷冻室124内储藏的食品(即，所储藏的物品)，或创建此类所储藏物品的清单。此类特征将在下文进行更详细的讨论。
图3提供了冰箱100的示意图。冰箱100包括控制器150，该控制器150可操作地联接到冰箱100的制冷系统(未示出)中配置成用于冷却食物保鲜室122或冷冻室124的部件或与之通信。这些部件包括压缩机170、蒸发器风扇172和冷凝器风扇174。控制器150可以可选择地操作这些部件，以便冷却食物保鲜室122或冷冻室124。控制器150还与温控器(例如，热电偶或热敏电阻)通信。温控器可以位于食物保鲜室122或冷冻室124(图2)中。控制器150可以从温控器接收与食物保鲜室122或冷冻室124的温度相对应的信号。控制器150还可以包括用于计算经过的时间段的内部计时器。
控制器150可以包括存储器和一个或多个微处理器、CPU等，诸如可操作成执行与冰箱100的操作相关联的编程指令或微控制代码的通用或专用微处理器。存储器可以表示诸如动态随机存取存储器(DRAM)之类的随机存取存储器，或者诸如只读存储器(ROM)或FLASH之类的只读存储器。在一些实施例中，处理器执行存储器中存储的非临时编程指令。对于某些实施例，这些指令包括配置成操作冰箱100或执行操作例程的软件包。存储器可以是与处理器分离的部件，或者可以在包含在处理器内的板上。可替代地，控制器150可以构造成不使用微处理器(例如，使用离散模拟或数字逻辑电路的组合；诸如开关、放大器、积分器、比较器、触发器、以及门等)执行控制功能以代替依靠软件。
控制器150可以位于整个冰箱100中的各个位置。可以在控制器150与冰箱100的各个操作部件之间对输入/输出(“I/O”)信号进行路由。冰箱100的一个或多个部件可以经由一根或多根传导信号线或共享通信总线与控制器150通信(例如，电通 信)。附加地或可替代地，冰箱100的一个或多个部件可以经由一个或多个无线信号频带与控制器150通信(例如，无线通信)。

现在大致转到图4至14，提供了搁架组件200的示例性实施例的各个视图。如图所示，搁架组件200包括一个或多个安装支架242和搁架224(例如，同图2的搁架144一起被包括或作为搁架被包括)连同一个或多个重量传感器210。组装时，安装支架242可以附接到箱体102(图2)，诸如食物保鲜室122的后部。在一些实施例中，安装支架242安装在食物保鲜室122的内胆上或作为一部分安装在内胆中。附加地或可替代地，安装支架242可以包括或提供为竖直延伸的导轨。在示出的实施中，安装支架242安装到内胆的后壁240(例如，经由一个或多个机械紧固件、粘合剂等)。可选地，可以将多个安装支架242固定到支撑面板212上，以可选择地附接一个或多个搁架224。举例来说，安装支架242可以固定到箱体102的后壁240，而一个或多个搁架224可以相对于安装支架242(例如，按照用户的引导)移动。在一些这样的实施例中，安装支架242限定了第一搁架224或第二搁架224可以附接到的多个不同高度。作为示例，这些不同高度可以通过对应的孔洞或凹槽提供，搁架224的配合钩228或接合凸片230可以悬挂或保持在这些孔洞或凹槽中。
一般，单独的搁架224包括用于接收放置在对应的冷冻间室(例如，食物保鲜室122)内的所储藏物品或物体的平台或表面。在一些实施例中，搁架224包括水 平平台232(例如，由诸如固态聚合物、玻璃、陶瓷或金属之类的刚性材料形成)。水平平台232可以与悬臂支架226结合，悬臂支架226从水平平台232向后延伸，以便将单独的搁架224附接到安装支架242上。悬臂支架226的至少一部分可以从水平平台232(在其下方或上方)竖直偏移。在示例性实施例中，悬臂支架226设置在水平平台232下方。组装时，悬臂支架226可以将搁架224保持到安装支架242上。举例来说，悬臂支架226可以可选择地与安装支架242(例如，在一个或多个预定义的沟道或凹槽处)结合。可选地，悬臂支架226可以包括配合钩228或接合凸片230，配合钩228或接合凸片230可以插入安装支架242中，以将搁架224保持在预定高度(例如，在食物保鲜室122内)。
在一些实施例中，提供了多个不同的搁架224。这样的搁架224可以彼此间隔开。作为示例，两个或更多个搁架224可以沿竖直方向V间隔开。作为附加或可替代的示例，两个或更多个搁架224可以沿侧向L间隔开。结果，可以限定出多个可在其上收容所储藏物品的表面平面。可选地，可以将多个搁架224附接到一个或多个公共安装支架242上。因此，第一搁架224和第二搁架224可以经由一个或多个相同的安装支架242附接到箱体102上。在一些实施例中，搁架224中的一个或多个可以可选择地可移动地安装，使得可以改变将至少一个搁架224保持在支撑平板212上的高度或侧向侧(例如，以在食物保鲜室122内容纳各种尺寸或形状的所储藏物品)。
如上所指出的，在箱体102内设置一个或多个重量传感器210。一般，至少一个重量传感器210设置在箱体102内并且配置成检测一个或多个对应搁架224上所储藏质量(即，放置在对应搁架224上的所储藏物品或物体的重量或质量)。具体地，重量传感器210配置成经由悬臂接合检测所储藏质量。因此，重量传感器210可以设置成与一个或多个对应的搁架224以悬臂接合。举例来说，箔式应变仪可以在从对应搁架224的水平平台232竖直偏移的点处接收传递到其上的横向力。有利地，重量传感器210可以提供对相应搁架224的重量或质量检测，而不需要直接在搁架224下方(例如，在食物保鲜室122内)布设电线或连接，否者布设电线或连接可能会使组件复杂化或干扰日常使用。
在一些实施例中，重量传感器210附接或固定至传感器壳体250上，传感器壳体250可以支撑或容纳重量传感器210的至少一部分。举例来说，传感器壳体250可以包括限定了袋状部的单元主体252，重量传感器210保持在该袋状部内。传感器壳体250本身可以同食物保鲜室122一起设置(例如，以可选的或固定的方式)。 而且，传感器壳体250可以相对于一个或多个安装支架242移动。具体地，传感器壳体250可以在箱体102内相对于固定的安装支架242移动，或者传感器壳体250可以固定安装在箱体102内，同时允许安装支架242相对于箱体102和传感器壳体250的一部分进行一定程度的平移或旋转。
现在特别转到图4至8，在示例性实施例中，重量传感器210设置在安装支架242后面。具体地，重量传感器210在食物保鲜室122后部安装在安装支架242后面。如图所示，安装支架242可以限定一个或多个孔隙254，可以通过孔隙254收容搁架224或悬臂支架226的一部分。举例来说，可以通过孔隙254收容接合凸片230。可以通过另一孔隙254(例如，在接合凸片230上方)收容配合钩228。在一些这样的实施例中，安装支架242限定了第一搁架224或第二搁架224可以附接到的多个不同高度。作为示例，这些不同高度可以通过对应的孔隙254提供，搁架224的配合钩228或接合凸片230可以悬挂或保持在这些孔隙中。
通过其收容接合凸片230的孔隙254可以与重量传感器210水平(例如，侧向或横向)对齐。当通过孔隙254设置时，接合凸片230可以延伸到重量传感器210并抵靠(例如，直接或间接)其设置。在一些这样的实施例中，悬臂支架226接触由传感器壳体250限定的弹性区域256(例如，在重量传感器210的前面)。使用期间，弹性区域256可以响应于通过接合凸片230引导的横向力而变形，并将这种力的至少一部分传递到重量传感器210。
在某些实施例中，传感器壳体250或重量传感器210可移动地同箱体102一起安装(例如，在食物保鲜室122内)。具体地，传感器壳体250和重量传感器210的竖直高度(即，沿竖直方向V相对于箱体102的位置)可以是可调节的(例如，手动或自动)。在一些这样的实施例中，传感器壳体250可以可滑动地安装到安装支架242。因此，传感器壳体250沿或相对于安装支架242竖直移动(例如，滑动)。这样的移动可以由用户基于提供给控制器150的输入手动或自动引导。在一些这样的实施例中，如将理解的，诸如线性致动器(未图示)之类的电子马达附接到壳体上，以驱动传感器壳体250(例如，向上或向下)。可选地，可以为传感器壳体250(并因此为重量传感器210)限定多个不同高度。这样的高度一般可以对应于搁架224的预定义高度。进而，不论搁架224移动至什么高度，用户都可以确保重量传感器210可以由搁架224接合。
在图4至8示出的实施例中，倒钩式后导轨258安装在箱体102内。如图所示，倒钩式后导轨258可以从安装支架242向后(例如，直接在后面)设置。组装时， 传感器壳体250可以保持在倒钩式后导轨258和安装支架242(例如，沿横向T)之间。因此，可以限制传感器壳体250的横向移动。
倒钩式后导轨258可以布置成使得其倒钩竖直间隔开并且可以进而限定出多个高度(例如，用于支撑传感器壳体250)。此外，倒钩式后导轨258可以固定到限定了食物保鲜室122的内胆或相对于其固定。传感器壳体250可以包括一个或多个与倒钩式后导轨258的倒钩互补的接触齿260。经组装的搁架组件200可以使接触齿260可选择地与倒钩式后导轨258的一个或多个倒钩接合，以将传感器壳体250保持在可变高度。具体地，通过互补布置，接触齿260可以接合后导轨258的倒钩，并进而将传感器壳体250保持在所选高度。尽管如此，诸如通过在一个高度将传感器壳体250的齿从倒钩式后导轨258的一个或多个倒钩上提起，将传感器壳体250竖直滑动到某个其他高度，并将齿放置在对应于该其他高度的倒钩式后导轨258的倒钩上，可以使传感器壳体250可选择地沿竖直方向V移动。可选地，前手柄262可以从传感器壳体250延伸(例如，远离接触齿260向前或横向延伸)，与允许用户沿安装支架242或倒钩式后导轨258轻松握住并操纵传感器壳体250。
现在特别转到图9和10，在示例性实施例中，重量传感器210可以直接附接到搁架224。举例来说，重量传感器210可以固定到水平平台232下方的悬臂支架226。在一些这样的实施例中，传感器壳体250固定到悬臂支架226。可选地，传感器壳体250可以设置在配合钩228下方。如上所述，对于图4至8，搁架224可以可选择地移动到安装支架242上的不同高度。然而，与这些实施例相反，传感器壳体250可以同对应的搁架224一起移动，从而可选择地从安装支架242分离。
在一些这样的实施例中，在重量传感器210和冰箱100的另一部分(例如，图3控制器150)之间建立可选择的电连接。具体地，插座连接杆264和连接插头266可以限定出允许信号从重量传感器210传递到电器100的另一部分的传导路径。如图所示，插座连接杆264可以从安装支架242向后(例如，直接在后面)设置。插座连接杆264可以接线到箱体102的另一部分并限定出多个与安装支架242的多个对应孔隙254对齐的多个插孔268。连接插头266可以从单元主体252向后延伸，以通过安装支架242的这些孔隙254被收容。组装时，连接插头266可以与至少一个插孔268结合，从而在二者之间建立电通信。
特别地，转到图11和12，可以提供支撑面板212用来将安装支架242附接到箱体102。举例来说，支撑面板212可以在支撑面板212的顶端固定到箱体102。安装支架242可以固定到支撑面板212。此外，多个间隔开的搁架224可以附接到 支撑面板212。举例来说，搁架224可以从支撑面板212向前固定到一个或多个安装支架242，使得支撑面板212从一个或多个搁架224向后设置。重量传感器210可以与一个或多个(例如，所有)搁架224间隔开安装在箱体102或支撑面板212上。在某些实施例中，重量传感器210设置在搁架224下方。具体地，重量传感器210可以安装在支撑面板212的底端或其附近。如图所示，重量传感器210可以夹在箱体102和支撑面板212之间以和二者悬臂接合。有利地，重量传感器210可以检测跨多个不同搁架224的质量负载。
特别地，转到图13和14，与图11和12的实施例类似，重量传感器210可以设置在抽屉支撑搁架248附近。在一些实施例中，抽屉支撑搁架248包括或附接到一个或多个滑动支架270，用于收容滑动储藏抽屉142(图2)。反过来，一个或多个滑动支架270可以安装到支撑面板212(例如，经由抽屉支撑搁架248)。此外，储藏抽屉142可以可滑动地收容在滑动支架270上。举例来说，储藏抽屉142可以可滑动地收容在抽屉支撑搁架248下方。重量传感器210可以安装在储藏抽屉142上方。有利地，重量传感器210可以检测多个不同搁架224(例如，靠近相对的面板侧)上的质量负载，并通过滑动支架270(例如，在抽屉支撑搁架248处)保持。
大致回到图2至14，在某些实施例中，图像模块160和控制器150配置成捕获一张或多张二维图像。可选地，多张连续的二维图像可以作为图像捕获序列的一部分而被捕获(例如，以预定或模式)。可以在控制器150处记录(例如，临时地)并比较连续的图像(例如，先前捕获的图像和最近捕获的图像)。通过比较，可以检测到连续图像之间的变化或差异。可选地，根据一个或多个结束条件，诸如预定时间段到期、无法检测到连续图像中的其他变化、或关闭门128，随后可以停止或暂停图像捕获序列。
独立于或除了所捕获的图像，重量传感器210和控制器150可以配置成检测搁架组件200的搁架224或抽屉142上的物体质量或重量(例如，根据预定计划的或串联的图像捕获序列)。这样的检测可以生成捕获的质量负载。
根据所捕获的图像和一个或多个质量负载，控制器150可以自动尝试识别图像模块160的视野内的物品(例如，所储藏物品，诸如食物；或非储藏物品，诸如用户附属物、搁架、可移动抽屉等)。如所理解的，识别这样的物品可以通过以下方式执行：边缘匹配、分冶法搜索、灰度匹配、感受野响应直方图或另一合适的例程(例如，基于来自图像模块160的一个或多个捕获的图像在控制器150处执行)。识别可以包括或尝试估计所储藏物品的标识(例如，识别什么类型的食物和物体)或数量 (例如，不同单元数量、体积或质量)。
本书面描述使用示例来公开本发明(包括最佳实施方式)，并且还使本领域技术人员能够实施本发明，其中包括制造和使用任何装置或系统并且执行所包含的任何方法。本发明的可获得专利范围由权利要求书限定，并且可以包括本领域技术人员能够想到的其它示例。如果此类其他示例包括与权利要求的字面语言并无区别的结构元件，或者如果此类其他示例包括与权利要求的字面语言没有实质性区别的等效结构元件，此类其他示例则包含在权利要求的范围内。
