Therefore, when the coil spring 340 is in the extended position, a force can be exerted on the guide post 330 along the direction of the front end 338 of the basket lifting assembly 300. This force can help the motor 310 to lift the storage basket 306 and its contents, thereby reducing the torque required by the motor 310. Additionally or alternatively, when the storage basket 306 is in the raised position, the guide post 330 may be closest to the front end 338 of the storage basket lifting assembly 300.

Description

储物篮提升组件以及具有其的制冷电器 技术领域
本发明一般涉及制冷电器的储物篮提升组件，用于电动升降储物篮。
背景技术
制冷电器一般包括箱体，所述箱体界定了用于容纳储藏食物的一个或多个隔热间室。某些制冷电器包括将食物储藏在水冰点以上的保鲜室和将食物储藏在水冰点以下的冷冻室。保鲜室和冷冻室可在箱体内相对于彼此设在不同的位置。消费者通常更喜欢能方便地看到和触及其中所储藏的食物的冷藏室。但是，制冷电器的箱体内保鲜室和冷冻室的布置会影响食物的可见性和可及性。
在某些制冷电器(通常称作对开门制冷电器)中，箱体内的保鲜室紧挨在冷冻室旁边。此种布局可以方便用户取用储藏在制冷电器门上的食物。在其它制冷电器(通常称作底置型制冷电器)中，箱体内的冷冻室位于保鲜室的下方。此种布局可以提供较宽的保鲜室或冷冻室。但是，在这两种情况下，均利用了隔热间室的地板附近的空间，特别是对于年老体弱的使用者而言，这让取用变得困难。
许多制冷电器通过在隔热间室的下部提供抽屉来解决这个问题，使得用户需要向下到达冰箱的底部并向内伸向冰箱的后部。尽管这种解决方案确实有助于取用，但是它们并未解决根本的问题，即食物在抽屉内储藏得太低而使得许多用户不弯腰或跪下就无法够到。
因此，具有带电动储物篮提升组件的可滑动抽屉的制冷电器在提高对制冷电器内装物的可及性方面将很有用。

具体实施方式
现在将详细参考本发明的实施例，在附图中说明了其一个或多个示例。每个示例均用于对本发明进行解释说明，而非对其进行限制。实际上，对于本领域技术人员来说显而易见的是，在不脱离本发明的范围或精神的情况下，可以对本发明进行各种修改和变型。例如，作为一个实施例的一部分说明或描述的特征能与另一实施例一起使用以产生又一实施例。因此，本发明旨在涵盖所附权利要求及其等同物的范围内的此类修改和变型。
为了帮助理解本公开内容，下面定义了几个词语。所定义的词语应理解为具有与本发明相关领域的普通技术人员通常认可的含义。类似地，“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”)。“第一”，“第二”和“第三”可互换使用，以将一个组件与另一个组件区分开，且并不旨在表示各个组件的准确位置或重要性。“内”和“外”等词语是指相对于制冷电器的内部和外部的相对方向，特别是相对于其中界定的食物储藏室。例如，“内”或“向内”是指朝向制冷电器内部的方向。 “左”、“右”、“前”、“后”、“顶部”或“底部”等词语是参照用户接近制冷电器的视角。例如，用户站在冰箱前面打开冰箱门，并伸手进食物储藏室内取用其中的食物。
现在参考图1至图3，图中提供了根据本公开的示范性实施例的制冷电器10的多个视图。图1是制冷电器10的正视图。图2是示范性制冷电器10的侧视图。图3是制冷电器10的正面立体图，其中显示一对冰箱门40、50处于打开位置。
通常，制冷电器10包括壳体或箱体12，所述壳体或箱体界定了竖向V、侧向L和横向T(例如，见图2)，每个方向彼此相互垂直。如图所示，箱体12沿着竖向V在顶部14和底部16之间延伸，沿着侧向L在第一侧(例如，左侧)18和第二侧(例如，右侧)20之间延伸，并沿着横向T在前侧22和后侧24之间延伸。
箱体12界定一个或多个隔热间室99，隔热间室99可包括单独的保鲜室100和冷冻室102，用于容纳和储藏食物。特别地，保鲜室100设在箱体12的顶部14或靠近顶部14设置。冷冻室102沿着竖向V设在保鲜室100的下面。(例如，在箱体12的底部16或靠近底部16)。但是，应当理解，保鲜室和冷冻室100、102可设在制冷电器10内的另一个合适的位置。
制冷电器10还可包括用于分配液态水或冰的分配组件132。分配组件132包括分配器134，所述分配器134位于或安装在制冷电器10的外部，例如在冰箱左侧门50上。另外，如下面更详细的描述，制冷电器10可包括储物篮提升组件300(例如，如图6的实施例所示)，所述储物篮提升组件设在冰箱门40、50的下面，用于选择性地取用冷冻室102内的食物。
制冷电器10还包括控制器144，所述控制器144一般用于调节制冷电器10。控制器144可与分配组件132通信(例如，电耦合)。在示范性实施例中，控制面板可作为通用I/O(“GPIO”)设备或功能块。在其它示范性实施例中，控制面板包括多个输入组件，如旋转拨盘、按钮和触摸板、触屏等各种电气、机械或机电输入设备中的一种或多种。控制面板可通过一条或多条信号线或共享的通信总线与控制器144通信(例如，电耦合)。
控制器144包括存储器以及一个或多个处理设备(如微处理器、CPU等)，如可用于执行与制冷电器10的工作相关的编程指令或微控制代码的通用或专用微处理器。存储器能表示诸如DRAM的随机存取存储器，或者诸如ROM或FLASH的只读存储器。处理器执行存储在存储器中的非传递性编程指令。存储器可以是与处理器分离的组件，也可以包含在处理器本身内部。或者，可以不使用微处理器来构造控制器144，例如，使用分立的模拟或数字逻辑电路(例如，开关、放大器、积分 器、比较器、触发器、与门等)的组合来执行控制功能，而不是依靠软件。
在一些实施例中，制冷电器10可包括附接到门154的把手152。包括门154在内的储物篮提升组件300可以滑动地安装于箱体12。因此，使用者可以利用把手152沿着横向T将储物篮提升组件300拉进拉出冷冻室102。
通常，门154在第一侧218和第二侧220之间沿着侧向L延伸，并在顶部214和底部216之间沿着竖向V延伸。如图所示，门154包括外表面158(例如，远离箱体12)和内表面160(例如，朝向箱体12)，外表面158和内表面160沿侧向L从第一侧218向第二侧220延伸。组装后，门154可选择性地盖住箱体开口162，通过所述箱体开口，可进入冷冻室102。
如图3所示，可在保鲜室100内安装各种储藏组件，以大体上便于食物的储藏。在某些实施例中，储藏组件包括门搁架116、抽屉120和搁架122，门搁架116、抽屉120和搁架122安装在保鲜室100内。门搁架116、抽屉120和搁架122构造成用于容纳食物(例如，饮料或固体食物)，并且可以帮助整理这些食物。
参考图4至图5，图中提供了制冷电器10(尤其是冷冻室102)的示范性实施例的多种示意图。如图4和图5，门154可滑动地安装至箱体12。具体来讲，门154可沿着横向T在基本打开位置(图5)和基本关闭位置(图4)之间移动。在基本打开位置，主要开口162总体上不被盖住，可以进入冷冻室102(例如，用户通过主要开口162)。相比之下，在关闭位置，主要开口162被基本盖住，限制进入冷冻室102。例如，门154可与箱体12接合，沿竖向V和侧向L跨越主要开口162(例如，参见图1)，从而沿横向T封住冷冻室102的至少一部分。在其它实施例中，门154可以枢转地安装至箱体12，从而在门154打开时露出主要开口162。
在一些实施例中，主密封垫172设在或附接在门154上(例如，在门154的内表面160上)。当门154移向所述关闭位置时，门154可接触并将主密封垫172压靠至箱体12的对应外表面。具体来讲，主密封垫172可抵靠箱体12的外表面进行密封，以封闭冷冻室102。在替代实施例中，主密封垫172可设在箱体12的外表面158，并且，随着门154朝所述关闭位置移动，箱体12可将主密封垫172压靠至门154的内表面160。更具体地讲，主密封垫172可以抵靠门154的内表面160进行密封。应当理解，主密封垫172可由任何合适的材料制成。例如，在一个实施例中，主密封垫172可由弹性橡胶或塑料材料制成。
现在参考图6、图7A和图7B，图中提供了储物篮提升组件300的示范性实施例的多种立体图。储物篮提升组件300通常可提升储物篮，以便更容易地取用篮内 所装的物品。特别地，储物篮提升组件300可包括支撑架组件302、储物篮306、第一连杆机构308、马达310和第二连杆机构312。通常，驱动马达310可导致与马达310相连接的第一连杆机构308产生转动。第一连杆机构308可连接至第二连杆机构312，从而第一连杆机构308的转动可导致第二连杆机构312发生线性平移和绕轴转动。储物篮306可进一步连接在第二连杆机构312上，从而第二连杆机构312的绕轴转动可导致储物篮306被提起。下面关于储物篮提升组件300、其部件及其相互作用的详细描述将进一步说明这些操作。
参考图6的实施例，支撑架组件302安装于箱体12，以便储物篮306可沿着横向T滑动，以收入冷冻室102。这样，支撑架组件302可以至少部分地容纳在冷冻室102内。支撑架组件302还可包括或界定用于支撑第二连杆机构312的水平导轨304，见下文进一步的描述。在一些实施例中，支撑架组件302包括第一支撑架332，所述第一支撑架332安装(例如，固定安装)在冷冻室102内。另外，支撑架组件302可包括滑动地连接于第一支撑架332的第二支撑架334。第二支撑架334可以在位于冷冻室102内的缩回位置(如图7B所示)和至少部分位于冷冻室102外部的伸出位置(如图7A所示)之间移动。在一些这种实施例中，储物篮306由第二支撑架334支撑，因此也可在所述缩回位置和所述伸出位置之间滑动。
此外，支撑架组件302还可包括安装框架336。在一些实施例中，安装框架336连接在第二支撑架334并且竖直定向。在采用安装框架336的实施例中，安装框架336可以界定水平导轨304，见上面关于支撑架组件302的一般描述，下面将作出进一步详细描述。在替代实施例中，储物篮提升组件300可相对于冷冻室102(或其它隔热间室99)静止不动(例如，不可滑动)。在一些此类实施例中，第二支撑架334将是不必要的，并且安装框架336可直接连接于第一支撑架332。在其它替代实施例中，第一支撑架332和安装框架336形成一个整体结构，所述整体结构安装在冷冻室102内或门154上。
如图6所示，可将门154安装(例如，固定地安装)于支撑架组件302。在特定实施例中，第二支撑架334连接于门154，并且可在驱动下与门154同步运动。换言之，(例如，当用户打开和关闭门154时，)第二支撑架334可与门154一起滑动。
在一些实施例中，储物篮306包括在储物篮提升组件300中。例如，储物篮306可滑动地安装于箱体12，以收入冷冻室102。可选地，储物篮306可附接于第二支撑架334，使得储物篮306还可在驱动下以与门154同步运动。
图7A和图7B是储物篮提升组件300的立体图，其中省略了储物篮306以便于 无阻碍地观察储物篮提升组件300的其余部分。如图7A和图7B所示，储物篮提升组件300还包括马达310，以提供提起储物篮306所需的至少一部分力。可选地，马达310采用自锁型蜗轮箱。有利的是，自锁型蜗轮箱抵抗由马达310产生的力，降低了马达310可运行的转速(例如，每分钟转数)。蜗轮箱的这种阻力可防止马达的意外转动，这种意外转动可能是由于所施加的负荷(例如，处于升起位置的储物篮306及其内装物的重量)而产生。另外或或者，马达310的转速降低直接转换为以较低的速度提升储物篮306，从而有利于储物篮306的安全运动。在其它实施例中，马达可以采用与本公开一致的本领域已知的其它类型的齿轮箱。
在某些实施例中，马达310可附接(例如，固定地附接)于耦合器309，所述耦合器309又可附接(例如，固定地附接)于轴311。轴311可以延伸穿过安装框架336，从而将其锚固于储物篮提升组件300。另外，第一连杆机构308可连接于轴311。这样，驱动马达310可导致耦合器309、轴311和第一连杆机构308产生转动。借助于上述轴311的锚固，第一连杆机构308可以(经由安装框架336)活动地附接于支撑架组件302。
同样如图8A至图8C所示，第一连杆机构308还可连接于第二连杆机构312。可以采用任何合适的连接方式(例如，键槽连接)。第二连杆机构312包括第一臂314和第二臂320。第一臂314具有第一端316和第二端318。同样地，第二臂320具有第一端322和第二端324。第一臂314的第一端316可连接于第一连杆机构308。另外，第一臂314的第二端318和第二臂320的第二端324在臂关节326处彼此连接，在第一臂314和第二臂320之间界定了小于180度的臂角(例如，固定臂角)。此外，第二臂320的第二端324连接于储物篮306，如图10的实施例所示，这样储物篮306可以活动地附接在支撑架组件302上。
再次参考图7A和图7B，第二连杆机构312还包括导柱330，所述导柱330连接在第二连杆机构312的臂关节326处。导柱330设在第二连杆机构312和水平导轨304之间，与水平导轨304相互作用并由水平导轨304支撑。水平导轨304可以采取脊、狭槽、凹槽或任何适用于支撑导柱330并限制其在竖向V上的运动范围的形式。另外，可在储物篮提升组件300(例如，支撑架组件302)的部分上方安装保护罩(未示出)，以确保使用者安全、美观或防止储物篮提升组件300的运动元件卡住。
可选地或有选择性地，可通过用户输入(例如，语音激活、按下按钮或触摸屏选择)驱动储物篮提升组件300。所述用户输入被传送到控制器144。当所述用户输 入反映了用户升起或降落储物篮306的意图时，控制器144可沿适应方向驱动马达310。在用户选择从所述降落位置升高储物篮306的情况下，提篮机构300可从图8A所示的位置开始。驱动马达310可使耦合器309和轴311发生转动。这些元件的转动可导致第一连杆机构308产生类似的转动。由于第一连杆机构308和第二连杆机构312之间存在连接，因此可迫使第二连杆机构312运动。因为第二连杆机构312可在臂关节326处连接在导柱330上，并且导柱330的运动可受到水平导轨304的约束，所以第二连杆机构312的运动可以大致平行于水平导轨304。此外，第二连杆机构312可绕导柱330所设置的臂关节326枢转，如图8B-8C所示。由于第二连杆机构312的这种枢转，可以升高第二连杆机构312的第二臂320。储物篮306附接于第二连杆机构312的第二臂320，可由于第二连杆机构312的运动而以同样的方式被升高，直到其处于升起位置(图8C)。以此方式，储物篮306可以活动地附接于支撑架组件302。有利的是，限制马达310的转动可使上述的储物篮提升组件300能够沿基本笔直的竖直线提升和降落储物篮306。如根据本公开能理解的，储物篮306保持基本竖直的距离至少部分取决于第一连杆机构308和第二连杆机构312的尺寸。
在可选实施例中，储物篮提升组件300还包括过载保护装置，以确保马达310不会过载。所述过载保护装置可采用称重传感器(未示出)，将其设在一个或多个承重连接处(例如，在第一连杆机构308与第二连杆机构312之间或第二连杆机构312与储物篮306之间)。称重传感器可以测量由提升储物篮306及其内装物产生的负荷。称重传感器可以构造成能将施加的负荷与电流消耗(例如，在马达310处)相关联，并在出现过载时中断马达310的驱动。
现在参考图9A和图9B，储物篮提升组件300还可包括螺旋弹簧340。螺旋弹簧340可定向成平行于支撑架组件302的水平导轨304。螺旋弹簧340可具有第一端342和第二端344。螺旋弹簧340的第一端342可连接于导柱330。螺旋弹簧340的第二端344可连接(例如，固定地连接)在储物篮提升组件300的前端338，所述前端338远离隔热间室99进行延伸。当储物篮306处于所述降落位置时，导柱330可在距储物篮提升组件300的前端338最远的位置(例如，沿横向T)处。因此，螺旋弹簧340处于伸展位置时，可沿储物篮提升组件300的前端338的方向在导柱330上施加力。该力可帮助马达310提升储物篮306及其内装物，从而减小马达310所需的扭矩。另外或或者，当储物篮306处于升起位置时，导柱330可以最接近储物篮提升组件300的前端338。这样，螺旋弹簧340就可处于缩回位置。有利的是，螺旋弹簧340可通过使储物篮306为了回到降落位置需克服螺旋弹簧340的张力，来 帮助维持储物篮306的升起位置。
在某些实施例中，储物篮提升组件300还包括第一提升状态传感器346和第二提升状态传感器348。如图9A和图9B所示，第一提升状态传感器346安装在支撑架组件302，并在储物篮306的降落位置时与导柱330对准。第二提升状态传感器348安装在支撑架组件302，并在储物篮306的升起位置时与导柱330对准。因此，当储物篮306处于降落位置时，导柱330触发第一提升状态传感器346，所述第一提升状态传感器346可提醒控制器144停止对马达310的驱动。同样地，当储物篮306处于升起位置时，导柱330触发第二提升状态传感器348，所述第二提升状态传感器348可提醒控制器144停止对马达310的驱动。
在其它实施例中，第一提升状态传感器346可在储物篮306处于降落位置时与第一连杆机构308对准，并且第二提升状态传感器348可在储物篮306处于升起位置时与第一连杆机构308对准。类似于先前讨论的实施例，第一提升状态传感器346和第二提升状态传感器348可在被第一连杆机构308触发后提醒控制器344停止对马达306的驱动。
在一些实施例中，第一提升状态传感器346和第二提升状态传感器348可以是限位开关。在其它实施例中，第一提升状态传感器346和第二提升状态传感器348中的一个或两个是霍尔效应传感器，其感测磁体的磁场，所述磁体安装在(例如)上述实施例中导柱330或第一连杆机构308上或中。某些实施例包括附加的提升状态传感器(例如，设在第一提升状态传感器346和第二提升状态传感器348之间)，例如用于在提升或降落时监测储物篮306的位置的指标，以确保过程按预期进行。
在一些实施例中，如图10所示，储物篮提升组件300包括开槽轴350，所述开槽轴350在储物篮306的后侧352上竖直延伸。另外或或者，储物篮提升组件300还可包括安装在支撑架组件302上的储物篮提升引导件354。在一些这种实施例中，储物篮提升引导件354包括在储物篮提升引导件354的前侧358的突出部356。通常，突出部356与开槽轴350匹配。在具体实施例中，突出部356可滑动地容纳在开槽轴350中。因此，随着储物篮306在降落位置与升起位置之间移动，突出部356在开槽轴350内滑动。有利的是，突出部356和开槽轴350之间的相互作用可防止储物篮306在升起状态和降落状态之间(例如，在升起位置和降落位置之间)过渡时出现倾斜。另外或或者，开槽轴350可设在门154的内表面并在其上竖直延伸。在一些这种实施例中，突出部356位于储物篮306的前侧上，与开槽轴350匹配，以便如前面所述可滑动地容纳在开槽轴350内。可选地，这种实施例可以不需要设 置储物篮提升引导件354。
该书面描述使用示例来公开本发明(包括最佳方式)，并让本领域的任何技术人员能够实践本发明，包括制作和使用任何设备或系统以及执行任何纳入的方法。本发明的可获得专利范围由权利要求书限定，并且可包括本领域技术人员能想到的其它示例。若这种其它示例包括与权利要求的字面语言并无不同的结构元件，或者若它们包括与权利要求的字面语言没有实质性差异的等效结构元件，则意欲将这些示例包含在权利要求书的范围内。
