Description

用于制冷电器的齐平安装灯组件 技术领域
本发明总体涉及制冷电器，更具体地涉及用于制冷电器内的改善照明的照明***。
背景技术
制冷电器通常包括箱体，该箱体具有用于接收食品以便储存的制冷间室。另外，制冷电器包括一个或多个门体，这些门体可旋转地铰接到箱体，以允许选择性地接近制冷间室中储存的食品。制冷电器还可以包括安装在制冷间室内并且设计成便于在其中储存食品的各种储存部件。这种储存部件可以包括在制冷间室内接收食品并且辅助管理和布置这种食品的搁架、盒、层架或抽屉。
特别地，为了提高制冷间室内的可视性，传统的制冷电器包括一个或多个灯，这些灯设置箱体内，用于在门体打开时照亮制冷间室。例如，这些灯可以沿着内衬的侧面和顶部设置，并且通常朝向制冷间室的前部设置，以更好地照亮消费者立即可见的层架和储存盒前部的物品。然而，传统的灯及其设置经常不能提供均匀的光，产生过多的眩光，或者产生制冷间室的不稳定且令人不愉快的照明。而且，这些灯通常安装到内衬，使得它们突出到制冷间室中，从而占据有用的内部空间并且成为层架移动、食品放置等的障碍物。
因此，具有改进的照明***的制冷电器将是有用的。更特别地，提供用于制冷电器的使整个制冷间室的明亮、均匀的照明同时占据非常小的空间的灯组件将是特别有益的。

具体实施方式
现在将详细地参照本发明的实施方式，其中的一个或多个示例示于附图中。每个示例都以对发明进行解释的方式给出，并不对本发明构成限制。实际上，对于本领域技术人员而言显而易见的是，能够在不偏离本发明的范围或者精神的前提下对本发明进行多种改型和变型。例如，作为一个实施方式的一部分示出或者进行描述的特征能够用于另一个实施方式，从而产生又一个实施方式。因此，期望的是，本发明覆盖落入所附权利要求及其等同形式的范围内的这些改型以及变型。
如本文所用的，术语“第一”、“第二”和“第三”可以互换使用以将一个部件与另一个部件区分开，并且这些术语并不旨在表示各个部件的位置或重要性。术语“上游”和“下游”是指相对于流体通路中的流体流动的相对方向。例如，“上游”是指流体流动的来向，而“下游”是指流体流动的去向。术语“包括(includes)”和“包括(including)”旨在以类似于术语“包括(comprising)”的方式为包括的。类似地，术语“或”通常旨在是包括的(即，“A或B”旨在意指“A或B或两者”)。
如本文在整个说明书和权利要求书中使用的近似语言被应用于修饰任何定量表示，该定量表示可容许在不导致其相关的基本功能改变的情况下变化。因此，由诸如“大约”、“近似”以及“大致”的术语修饰的值不限于所指定的精确值。在至少一些情况下，近似语言可对应于用于测量值的仪器的精度。例如，近似语言可以指在10％的裕度内。
现在参见附图，将描述根据本发明的示例性方面的示例性电器。具体地，图1提供了示例性制冷电器100的立体图，图2示例了一些门体处于打开位置的制冷电器100。如图示例，制冷电器100通常具有竖向V、侧向L和横向T，竖向V、侧向L和横向T中的每一个相互垂直，使得大体限定正交坐标系。
根据示例性实施方式，制冷电器100包括箱体102，该箱体通常用于容纳和/或支撑制冷电器100的各种部件，并且还可限定制冷电器100的一个或多个内部腔室或间室。在这点上，如本文所用的，术语“箱体”、“壳体”等通常旨在指用于制冷电器100的外框架或支撑结构，例如，包括由任何合适的材料形成的任何合适数量、类型和构造的支撑结构，诸如细长支撑构件、多个互连面板或其一些组合的***。应当理解，箱体102不一定需要围合，而是可以简单地包括支撑制冷电器100的各种元件的开放结构。相反，箱体102可以包围箱体102内部的一些或所有部分。应当理解，箱体102可具有任何合适的尺寸、形状和构造，同时保持在本发明的范围内。
如图示例，箱体102通常沿着竖向V在顶部104与底部106之间延伸，沿着侧 向L在第一侧108(例如，如图1中从前方观察时的左侧)与第二侧110(例如，如图1中从前方观察时的右侧)之间延伸，并且沿着横向T在前部112与后部114之间延伸。一般而言，诸如“左”、“右”、“前”、“后”、“顶部”或“底部”的术语是参考用户接近电器100的视角来使用的。
箱体102形成用于接收食品以便储存的制冷间室。特别地，箱体102具有设置在箱体102的顶部104处或与其相邻设置的食物保鲜室122和布置在箱体102的底部106处或与其相邻布置的冷冻室124。由此可见，制冷电器100通常被称为底置式冰箱。然而，认识到，本发明的益处适用于其他类型和样式的制冷电器，例如，顶置式制冷电器、对开门式制冷电器或单门制冷电器。而且，本发明的方面也可以适用于其他电器。因此，本文阐述的描述仅出于示例目的，而无意于在任何方面限于任何特定的电器或配置。
冷藏门体128可旋转地铰接到箱体102的边缘，以便选择性地进入食物保鲜室122。另外，在冷藏门体128的下方布置冷冻门体130，以便选择性地进入冷冻室124。冷冻门体130联接至可滑动地安装在冷冻室124内的冷冻抽屉(未示出)。通常，冷藏门体128用于密封箱体102的前开口132(例如，在由竖向V和侧向L限定的平面内延伸)。在这点上，当冷藏门体128打开时，用户可以通过前开口132将物品放置在食物保鲜室122内，然后可以关闭冷藏门体128以便于气候控制。冷藏门体128和冷冻门体130在图1中被示出为处于关闭位置。本领域技术人员将理解，其它腔室和门体构造是可行的，并且在本发明的范围内。
图2提供了在冷藏门体128处于打开位置的情况下示出的制冷电器100的立体图。如图2所示，如本领域技术人员将理解的，各种储存部件被安装在食物保鲜室122内，以促进食品在其中的储存。特别地，储存部件可以包括盒134和层架136。这些储存部件中的每一个用于接收食品(例如，饮料或/或固体食品)，并且可以辅助管理这种食品。如图所示，盒134可以安装在冷藏门体128上或者可以滑动安装在食物保鲜室122中的容纳空间中。应当理解，所示的储存部件仅用于说明的目的，并且可以使用其它储存部件，并且其它储存部件可以具有不同的尺寸、形状以及构造。
再次参见图1，将描述根据本发明的示例性实施方式的分配组件140。虽然将示例并描述分配组件140的几个不同的示例性实施方式，但类似的附图标记可用于指代类似的部件和特征。分配组件140通常用于分配液态水和/或冰。虽然在本文中示例并描述了示例性分配组件140，但应当理解，可以在保持在本发明的范围内的同时 对分配组件140进行各种变更和修改。
分配组件140及其各种部件可以至少部分地设置在形成于冷藏门体128中的一个上的分配器凹部142内。在这点上，分配器凹部142形成在制冷电器100的前侧112上，使得用户可以在不打开冷藏门体128的情况下操作分配组件140。另外，分配器凹部142设置在预定高度处，该预定高度方便用户取冰，并且使得用户能够在不需要弯腰的情况下取冰。在示例性实施方式中，分配器凹部142设置在接近用户的胸部水平的位置处。
分配组件140包括冰分配器144，该分配器包括用于从分配组件140排出冰的排放口146。被示出为拨片的致动机构148安装在排放口146下方，以便操作冰或水分配器144。在可选示例性实施方式中，可以使用任意合适的致动机构来操作冰分配器144。例如，冰分配器144可以包括传感器(诸如超声传感器)或按钮，而不是拨片。排放口146和致动机构148是冰分配器144的外部零件，并且安装在分配器凹部142中。与之相比，冷藏门体128可以具有容纳制冰机和储冰盒(未示出)的冰盒室150(图2)，该制冰机和储冰盒被构造成将冰供应至分配器凹部142。
设置控制面板152，以便控制操作模式。例如，控制面板152包括一个或多个选择输入154，诸如旋钮、按钮、触摸屏界面等，诸如水分配按钮和冰分配按钮，用于选择期望的操作模式，诸如碎冰或非碎冰。另外，输入154可以用于指定填充容积或操作分配组件140的方法。在这点上，输入154可以与处理装置或控制器156通信。在控制器156中生成的信号响应于选择器输入154控制制冷电器100和分配组件140。另外，可以在控制面板152上设置显示器158，诸如指示灯或屏幕。显示器158可以与控制器156通信，并且可以响应于来自控制器156的信号而显示信息。
如本文所用的，“处理装置”或“控制器”可以指一个或多个微处理器或半导体装置，并且不必限于单个元件。处理装置可以被编程为操作制冷电器100、分配组件140以及制冷电器100的其他部件。处理装置可以包括一个或多个存储元件(例如，永久存储介质)或与其关联。在一些这种实施方式中，存储元件包括电可擦可编程只读存储器(EEPROM)。通常，存储元件可以存储处理装置可访问的信息，包括可以由处理装置执行的指令。可选地，指令可以是软件或指令和/或数据的任意集合，该软件或指令和/或数据的任意集合在由处理装置执行时，使得处理装置执行操作。
仍然参见图1，将描述根据本发明的示例性实施方式的外部通信***170的示意图。通常，外部通信***170用于允许制冷电器100与一个或多个外部装置之间的交互、数据传送和其他通信。例如，该通信可以用于提供和接收操作参数、用户指 令或通知、性能特性、用户偏好或用于制冷电器100的改进性能的任何其它合适的信息。另外，应当理解，外部通信***170可用于传送数据或其它信息，以提高一个或多个外部装置或电器的性能和/或改进与这种装置的用户交互。
例如，外部通信***170允许制冷电器100的控制器156与制冷电器100外部的单独装置通信，该单独装置在本文中通常被称为外部装置172。如以下更详细描述的，这些通信可以使用有线或无线连接(诸如经由网络174)来促进。通常，外部装置172可以是与制冷电器100分开的任何合适的装置，该装置被配置为向用户提供和/或从用户接收通信、信息、数据或命令。在这点上，外部装置172可以是例如个人电话、智能电话、平板电脑、膝上型或个人计算机、可穿戴装置、智能家庭***或者另一移动或远程装置。
另外，远程服务器176可以通过网络174与制冷电器100和/或外部装置172通信。在这点上，例如，远程服务器176可以是基于云的服务器176，由此位于远处位置，诸如在单独的州、国家等。根据示例性实施方式，外部装置172可通过网络174(诸如因特网)与远程服务器176通信，以发送/接收数据或信息、提供用户输入、接收用户通知或指令、与制冷电器100交互或控制制冷电器等。另外，外部装置172和远程服务器176可以与制冷电器100通信以传送类似的信息。
通常，可以使用任何类型的有线或无线连接并且使用任何合适类型的通信网络来进行制冷电器100、外部装置172、远程服务器176和/或其它用户装置或电器之间的通信，下面提供了通信网络的非限制性示例。例如，外部装置172可以通过任何合适的有线或无线通信连接或接口(例如网络174)与制冷电器100直接或间接通信。例如，网络174可以包括局域网(LAN)、广域网(WAN)、个域网(PAN)、因特网、蜂窝网络、任何其他合适的短程或远程无线网络等中的一个或多个。另外，可以使用任何合适的通信装置或协议(诸如经由无线电、激光、红外、以太网类型的装置和接口等)来发送通信。另外，这种通信可以使用各种通信协议(例如，TCP/IP、HTTP、SMTP、FTP)、编码或格式(例如，HTML、XML)和/或保护方案(例如，VPN、安全HTTP、SSL)。
本文描述了根据本发明的示例性实施方式的外部通信***170。然而，应当理解，本文提供的外部通信***170的示例性功能和配置仅用作示例，以便于描述本发明的各方面。***配置可以变化，其他通信装置可以用于直接或间接地与一个或多个关联的电器通信，可以实施其他通信协议和步骤等。这些变化和修改被认为在本发明的范围内。
现在一般参见图3至图9，将描述根据本发明的示例性实施方式的可以用于照亮食物保鲜室122、冷冻室124或制冷电器100内的其它区域的灯组件200。更具体地，根据所示例的实施方式，制冷电器100包括多个灯组件200，这些灯组件安装到内衬202的侧壁并且沿着竖向V隔开。尽管下面描述了示例性灯组件200，但是应当理解，灯组件200的数量、尺寸、位置和构造可以改变，同时保持在本发明的范围内。
如上所述，制冷电器100包括箱体102，该箱体可以是外壳或壳体，该外壳或壳体用于容纳和/或支撑制冷电器100的各种部件，并且还可以限定制冷电器100的一个或多个内部腔室或间室。内衬202可以设置在箱体102的内部，并且可以与箱体102隔开，以在其间限定隔热空间204。该隔热空间204可以注入隔热泡沫或另一隔热材料，以帮助使制冷电器100的各个制冷间室隔热。内衬202可以由任何合适的材料并以任何合适的方式构造。例如，内衬202可以例如使用片状模塑料(SMC)热固性塑料或其他热塑性塑料压缩成型。根据另一些实施方式，灯组件200的部分可由任意其它合适的刚性材料形成。
为了照亮制冷电器的腔室，诸如食物保鲜室122，内衬202可以具有用于接收灯组件200的多个孔口206。值得注意的是，如上文简要解释的，安装到制冷电器的内衬的传统灯组件具有各种缺点。例如，传统的灯组件将太多的光引向食物保鲜室122的前部，例如引向制冷电器的用户。另外，传统的灯组件具有不足的照明强度和分布。为了将更多的光引向制冷间室的后部，这些传统的灯组件突出到腔中，从而占据了有用的空间并阻碍了层架的设置、用户的可视性等。如本文所述的灯组件200被设计为解决与传统灯组件相关的一些或所有问题。
如图5中最佳示出的，灯组件200可通常包括灯壳体210，该灯壳体设置在隔热空间204内且安装到内衬外表面212。灯壳体210通常用于支撑灯组件200的各种部件，并且可以包括孔214，通过该孔可以供应电力，例如，经由被束环216固定和支撑的电缆或线束(未示出)。灯壳体210可由任何合适的材料形成，并且可以以任何合适的方式安装在隔热空间204内。例如，灯壳体210可以使用粘合垫圈218固定到内衬外表面212。另外或可选地，灯壳体210可通过填充隔热空间204的隔热泡沫而在适当位置固定。
灯组件200还可包括控制板220，该控制板设置在灯壳体210内且用于支撑光源222。根据示例性实施方式，当灯壳体210安装在制冷电器100内时，灯组件的所有部件(例如包括控制板220和光源222)可以相对于制冷间室(例如，食物保鲜室122)完全设置在内衬202后面。通常，控制板220可以可操作地将光源222联接到 用于调节灯操作的任何合适的控制器，诸如制冷电器的控制器156。
光源222可以包括任何合适数量、类型、位置和配置的电光源，使用任何合适的光技术并且以任何合适的颜色照明。例如，根据所示例的实施方式，光源222包括发光二极管(LED)，取决于来自控制器156的控制信号，LED可以以单色照明(例如，白色LED)，或者可以以多个颜色照明(例如，多色或RGB LED)。然而，应当理解，根据可选实施方式，光源222可以包括任意其他合适的传统灯泡或光源，诸如卤素灯泡、荧光灯泡、白炽灯灯泡、发光棒、光纤光源等。
灯组件200还可以包括透镜230，该透镜设置在内衬202的孔口206内，并且通常用于折射或以其他方式引导光(例如，如图8中的附图标记232所通常标识的)到食物保鲜室122内。另外，透镜230可以用于促进灯组件200的齐平安装，例如，用于改善美学外观、更容易清洁表面、更少的障碍物等。更具体地，透镜230可以具有与内衬内表面236齐平或共面的外透镜表面234。
灯壳体210和透镜230可以包括用于将透镜230固定在齐平安装位置的特征。例如，根据所示例的实施方式，灯壳体210可以设置有一个或多个安装套筒或狭槽240。另外，透镜230可以设置一个或多个与之配合的连接臂242，这些连接臂远离内透镜表面244延伸，例如，延伸入隔热空间204或灯壳体210中。为了安装透镜230，连接臂242可以滑入狭槽240中，并且可以通过在靠近各个连接臂242的远端处设置的一个或多个卡扣特征246固定。应当理解，在本发明的范围内，在灯壳体210与透镜230之间的任何其它合适的机械接合都是可行的。
值得注意的是，尽管用于制冷电器的传统光源略微突出到制冷间室中以用于改进照明，但是如本文所述的光源222完全设置在内衬202后面。因此，透镜230可以被设计成改善光232的折射和重定向，使得可以用更均匀分布的光来更好地照亮食物保鲜室122，并且使得较少的光232被引向接近制冷电器100的前侧112的用户。
具体地，如图6至图8中最佳示例的，内透镜表面244可以限定多个折射槽250。如本文所用的，术语“折射槽”等通常旨在指在内透镜表面244上限定以改善光分布、均匀性等的任何轮廓、几何形状、形状或图案。例如，根据本发明的示例性实施方式，折射槽250是菲涅耳槽。例如如图6所示，折射槽250可以关于透镜230的焦轴252同心。另外，多个折射槽250中的每一个可以具有槽深度254，该槽深度在垂直于内透镜表面244的方向上测量。根据示例性实施方式，并且如图7中最佳示例的，折射槽250的槽深度254可以朝向透镜230的焦轴252变小，例如用于改善光分布。然而，根据诸如图9示例的可选实施方式，折射槽250可以替代地是线 性的或具有任何其它合适的轮廓。
通常，光源产生相对光源的对称光照。然而，透镜230通常可以被设计和构造为产生在食物保鲜室122内分布的非对称光输出。这样，透镜230可以将更多的光引向食物保鲜室122的后部，并且将更少的光引向电器的用户或引向接近箱体102的前部的开口。这可以通过折射槽250的设计以及透镜230、光源222的相对位置和方向以及各自的焦轴和方向的组合来实现。
例如，根据所示例的实施方式，透镜230在相对于外透镜表面234的中心偏心的位置处具有焦轴252。在这点上，例如，焦轴252可以设置在接近透镜230的外径向端，例如，在透镜230的中心与透镜230的外径向边缘之间的径向距离的50％、60％、70％、80％或更大处。另外，焦轴252可以定向为垂直于透镜230，例如垂直于外透镜表面234。另外，如图8中最佳示出的，光源222可以相对于透镜230的焦轴252和/或相对于透镜230的中心偏移(例如，当在平行于焦轴252的方向上观察时)。
光源222也可以被定向为使得它限定主照明轴线260。在这点上，照明轴线260可以是光源222的主照明方向，例如，垂直于光源222的表面或沿着光232分布的对称中心的方向。根据所示例的实施方式，照明轴线260以相对于垂直于内透镜表面244的方向(例如，或平行于焦轴252的方向)成角度262延伸。根据示例性实施方式，角度262可在大约5°至60°之间、在大约15°至45°之间、或大约30°。另外，角度262可以被选择为用于通过透镜230的更好的光分布并且用于将光朝向食物保鲜室122的后部引导。对灯组件200的其它变化和修改是可行的，并且在本发明的范围内。
如上所述，本发明的方面涉及用于冰箱的具有至少两个不同特性的照明装置或照明组件。例如，第一特性是照明装置的输出表面与冰箱腔的侧壁齐平，从而提供清洁的、现代的外观并且提高腔的可清洁性。另外，第二特性是照明装置在内表面上可以具有多个重复的菲涅耳特征，这些菲涅耳特征用于使光在离开照明装置时，成一定角度远离用户所处的腔的前部，并且替代地使光成一定角度朝向腔的后部以照亮腔的内容物。根据示例性实施方式，透镜的焦轴偏离LED光源的焦轴，使得菲涅耳特征的角度转向能力可以增强。
通常，照明装置可以包括三个主要部件，诸如壳体、LED板和具有粘合剂以将其保持在腔内衬的后侧上的适当位置的透镜。壳体可以是白色塑料材料，该材料将LED板和透镜保持在抵靠腔内衬的适当位置。板可以卡扣到壳体内的适当位置，并且透镜然后可以卡扣到适当位置以覆盖LED板。线束连接可以经由壳体中的单独开口， 该开口用橡胶索环密封。用于保持LED板的壳体中的卡扣特征可以成角度，使得LED板以30度角水平朝向冰箱腔的后部倾斜。
示例性实施方式使用同心环形槽来成形光输出，并且具有将光水平地转向为远离用户以及将光输出竖直地会聚以在冰箱的各个层架内提供聚光效果的能力。另外，或者可选地，第二示例性实施方式使用线性槽，并且仅使光在水平方向上转动。例如，该透镜可能不能竖直地会聚光，由此在腔内提供最均匀的照明。
本书面描述使用示例对本发明进行了公开(其中包括最佳实施例)，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意装置或***并且执行所包含的任意方法)。本发明的可专利范围通过权利要求进行限定，并且可以包括本领域技术人员能够想到的其它的示例。如果这种其它的示例包括与权利要求的字面语言没有区别的结构元件，或者如果这种其它的示例包括与权利要求的字面语言没有实质区别的等同结构元件，则期望这种其它的示例落入权利要求的范围中。
