Description

具有移门的门中门制冷电器 技术领域
本发明整体上涉及制冷电器，特别涉及具有一个或多个门的制冷电器。
背景技术
制冷电器一般包括限定了食物储藏室的箱体。另外，制冷电器一般还包括可旋转地铰接到箱体上的门，以允许可选择地取用储藏在食物储藏室内的食物。某些制冷电器通常被称为门中门制冷电器，其还可以包括外门，该外门可旋转地铰接到内门，以允许可选择地进入食物储藏室，或者可选地，食物储藏室位于内门和外门之间。另外，门中门电器还可以包括位于外门上的密封垫。因此，当外门处于关闭位置时，密封垫密封内门以封闭食物储藏室。
门中门制冷电器的传统运行方式是外门和内门中的每一个均可旋转，有时围绕相同的旋转轴旋转。因此，可能需要一种将外门闩锁到内门上的锁定机构。在某些传统设计中，外门上的闩锁接合内门上的闩销，以将外门锁定到内门，从而使用户能够可选择地打开外门或内门。然而，这些传统设计存在某些缺点。举例来说，锁定机构可能很容易发生故障，需要进行成本高昂的更换或维修。进一步地，用户每当想要进入特定的储藏室时，都必须操作闩锁。
因此，制冷电器消除了一个或多个上述缺点将会非常有利。特别地，尤其有利的是，采用门中门配置的制冷电器具有改善耐用性、提高易操作性或以其它方式延长电器使用寿命的特征(例如，同时消除了对闩锁或锁定机构的需要)。

具体实施方式
现在将详细介绍本发明的实施例，这些实施例的一个或多个示例已在附图中示出。所提供的每个示例均用于说明本发明，而不是用于限制本发明。实际上，对于本领域技术人员而言将显而易见的是，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改变。举例来说，作为一个实施例的一部分示出或描述的特征，可以和另一个实施例一起使用以形成又一个实施例。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。
如本文所使用的，术语“第一”、“第二”和“第三”可以互换使用，以便将一个部件或位置与另一个区分开来，并非用于指示各个部件的绝对位置或重要性。诸如“内”和“外”之类的术语是指相对于制冷电器(特别是其中限定出食物储藏室的制冷电器)的内部和外部的相对方向。例如，“内”或“向内”是指朝向制冷电器内部的方向。诸如“左”、“右”、“前”、“后”、“顶部”或“底部”之类的术语，是参照用户进入制冷电器的角度使用的。例如，用户站在冰箱前打开门并把手伸进食物储藏室以取用其中的物品。
现在参照图1至图3，根据本发明实施例的制冷电器10具有竖直方向V、侧向L和横向T(例如，参见图2)，各方向彼此相互垂直。可以看出，制冷电器10包括壳体或箱体12，该壳体或箱体在顶部14和底部16之间沿竖直方向V延伸，在左侧18和右侧20之间沿侧向L延伸，并且在前侧22和后侧24之间沿横向T延伸(例如，参见图2)。
箱体12一般具有用于收容食品进行储藏的食物储藏室100(图3)。特别地，食物储藏室100位于箱体12的顶部14或其附近。然而，应当理解，食物储藏室100可以位于制冷电器10内的任何合适的位置。例如，在一个实施例中，食物储藏室100可以沿竖直方向V从顶部14延伸到底部16。
制冷电器10可以包括一个或多个冰箱门40、50，该一个或多个冰箱门可旋转地安装到箱体，例如，使得冰箱门40、50允许可选择地进入食物储藏室100。如图所示，在一些实施例中，冰箱门40、50包括右冰箱门(例如，第一侧门)40和左冰箱门(例如，第二侧门)50。右冰箱门40可以在箱体12的右侧20可旋转地安装到箱体12上。左冰箱门50可以可旋转地安装到箱体12的左侧18。右冰箱门40可以围绕第一枢轴450枢转。左冰箱门50可以围绕第二枢轴550枢转。把手108可以位于冰箱门40、50中的每一个上，以便在完全关闭位置(图1)和完全打开位置(图3)之间移动门40、50。
制冷电器10还可以包括用于分配液态水和/或冰的分配器组件132。分配器组件132包括分配器134，该分配器可以位于或安装到制冷电器10的外部，例如左冰箱门50上。另外或可选地，制冷电器10可以包括冷冻抽屉150，该冷冻抽屉布置在冰箱门40、50下方，用于可选择地取用冷冻食物储藏室(未示出)内的物品。冷冻抽屉150可以包括把手152。相应地，冷冻抽屉150可以沿横向T移入和移出冷冻食物储藏室(未示出)。
如图3所示，各个储藏部件可以安装在食物储藏室100内，以便一般储藏食品。在某些实施例中，储藏部件包括安装在食物保鲜室100内的盒体116、抽屉120和搁架122。这些盒体116、抽屉120和搁架122配置成用于收容食品(例如，饮料和/或固态食品)并且可以有助于整理这些食品。
现在总体上参考图4A至图7，制冷电器10可以配置为门中门冰箱。特别地，右冰箱门40可以用包括外门102和框架门105的嵌套门组件替换。在另一个实施例中，左冰箱门50可以用嵌套门组件替换。在又一个另选实施例中，冰箱门40、50都可以用嵌套门组件替换。
如图所示，外门102可以以滑动方式连接到框架门105。举例来说，框架门105还可以具有竖直方向V、侧向L和横向T，各个方向彼此相互排斥。如上所述，制冷电器可以包括右冰箱门40和左冰箱门50。相应地，右冰箱门40可以包括框架门105和外门102。类似地，左冰箱门50可以包括框架门105和外门102。在一些实施例中，右冰箱门40和左冰箱门50中只有一个包括框门105和外门102。
右外门102可以配置成相对于右框架门105沿第一方向滑动。举例来说，当从前面看制冷电器10时，右外门102可以相对于右框架门105主要侧向滑动。换言之，在打开运动期间，右外门102可以相对于右框架门105沿第一方向平移。如以下进一步所述，第一方向可以涵盖侧向部分和横向部分。相应地，在右外门102沿第一方向远离右框架门105平移的同时，右框架门105可以保持静止。类似地，在关闭运动期间，右外门102可以沿与第一方向相反的方向朝右框架门105平移。另外或可选地，右外门102在整个打开和关闭运动中可以与右框架门105保持平行。右外门102可以配置为相对于左框架门105沿第二方向滑动。举例来说，当从前面看制冷电器10时，左外门102可以相对于右框架门105主要侧向滑动。换言之，在打开运动期间，左外门102可以相对于左框架门105沿第二方向平移。与第一方向类似，第二方向可以涵盖侧向部分和横向部分。相应地，在左外门102沿第二方向远离左框架门105平移的同时，左框架门105可以保持静止。类似地，在关闭运动期间，左外门102可以沿与第二方向相反的方向朝左框架门105平移。另外或可选地，右外门102在整个打开和关闭运动中可以与右框架门105保持平行。在一些实施例中，第二方向与第一方向不同。举例来说，第一方向可以是第二方向关于在竖直方向V和横向T中限定的平面的等反射。
如上所述，框架门105可以可旋转地连接到箱体12。相应地，外门102可以以滑动方式连接到框架门105。举例来说，滑动组件200可以连接在外门102和框架 门105之间。滑动组件200可以是多级滑动。举例来说，滑动组件200可以包括连接到框架门105的第一滑轨202，连接到外门102的第二滑轨204，以及连接在第一滑轨202和第二滑轨204之间的第三滑轨206。应当注意，如将理解的，滑动组件200中包括的级数不受限制，并且可以根据应用需求包括更多或更少的级。第一滑轨202可以从框架门105延伸。第一滑轨202可以是能够允许另一个细长金属件(例如，以下所述的第二导轨204)相对于第一滑轨202滑动的细长金属件。另外或可选地，第一滑轨202可以被限定为内部侧轨(例如，靠近箱体12)。第一滑轨202可以具有允许第二滑轨204相对于其滑动的任何合适的形状。
第二滑轨204可以从外门102延伸。第二滑轨204可以与第一滑轨202滑动连接。举例来说，第二滑轨204可以与第一滑轨202共线。在一些实施例中，第二滑轨204可以容纳在第一滑轨202内。换言之，第二滑轨204和第一滑轨202可以构成嵌套联接。另外或可选地，第二滑轨204可以被限定为外部侧轨(例如，远离箱体12)。另外或可选地，第三滑轨206可以包括在滑动组件中。举例来说，第三滑轨206可以连接在第一滑轨202和第二滑轨204之间。例如，第三滑轨可以是传统抽屉滑轨。因此，第三滑轨206可以嵌套在第一滑轨202和第二滑轨204之间，使得滑动组件200构成三杆滑动组件。在一些实施例中，第一、第二和第三滑轨202、204、206可以各自包括多个轨道和多个滚珠轴承。应当理解，抽屉滑道在本领域中是众所周知的，因此简洁起见，将省略其详细说明。
简要参考图6A和图6B，滑动组件200可以相对于侧向L以预定角度Θ延伸。该预定角度Θ可以足以限制或消除对设置在外门102和框架门105之间的密封垫的刮擦。该预定角度Θ可以为大约20度、15度、10度。然而，应当理解，可以使用任何合适的角度。相应地，当外门102从关闭位置移动到打开位置时，外门102可以沿侧向L和横向T平移。例如滑动组件200可以定向成使得滑动运动沿滑动轴300进行。当用户希望将外门102从关闭位置移动到打开位置时，该用户可以主要沿侧向L(即，沿滑动轴300的方向)拉动把手108。因此，在外门102滑动到打开位置的同时，框架门105保持关闭。相应地，外门可以沿侧向L以及横向T远离箱体12移位。应当理解，如本文所用，诸如“约”、“基本上”或“大约”之类的近似术语是指在百分之十的误差范围内。
另外或可选地，滑动组件200可以采用任何合适的形状。举例来说，滑动组件200可以具有弯曲形状。具体而言，第一滑轨202可以沿横向T弯曲。根据具体应用，第一导轨202的弯曲可以是凸形的或凹形的。相应地，第二滑轨204可以具有 与第一滑轨202相等的弯曲。第二滑轨204可以相对于第一滑轨202沿弯曲路径滑动，从而使外门102相对于框架门105沿弯曲路径滑动。在一些实施例中，滑动组件200可以由滚柱和导轨组件构成。例如，导轨可以附接到框架门105，并且一个或多个滚柱可以附接到外门102。相应地，当外门102在关闭位置和打开位置之间移动时，外门102上的滚柱可以沿导轨在框架门105上滚动。
可以设置多个滑动组件200。举例来说，第一滑动组件200可以设置在框架门105顶部或其附近。另外或可选地，第二滑动组件200可以设置在框架门105底部或其附近。第一滑动组件和第二滑动组件200可以彼此平行。相应地，外门102可以相对于框架门105而被完全支撑并且可以以平滑无阻碍的方式打开。应当注意，根据具体实施例可以使用任何合适数量的滑动组件200，从而相对于框架门105对外门102进行支撑。第二滑动组件200(以及任何附加的滑动组件)可以构造成类似于以上所讨论的滑动组件200，如此，简洁起见将省略对其的详细说明。
滑动组件200还可以包括撞击器380，该撞击器从第二滑轨204延伸，例如沿横向V远离外门102延伸。另外，滑动组件200可以包括软关闭机构382，该软关闭机构安装到第一滑轨202并且配置成当外门102朝关闭位置移动时与撞击器380接合。然而，应当理解，根据另选实施例，软关闭机构382可以安装到第二滑轨204而撞击器380可以固定到第一滑轨202上的另一个位置或框架门105的另一个区域，从而使其在外门102在如图4所示的打开位置和如图1所示的关闭位置之间移动时与软关闭机构382接合。然而，应当理解，根据另选实施例，撞击器380和软关闭机构382的位置可以分别设置到框架门105和外门102上的其他位置，从而将撞击器380配置成当外门102在打开位置和关闭位置之间移动时与软关闭机构382接合。如本文所用，软关闭机构382用于指经设计充当阻尼器的装置、机构和组件，用于减慢或降低外门102速度，同时还接合外门102并提供辅助或作用力来将外门102移动到如图1所示的完全关闭位置。
现在具体参考图8和图9，将根据本发明的示例性实施例描述软关闭机构382接合撞击器380以促进外门102的软关闭操作的方式。就这一点而言，图8提供了撞击器380的透视图，该撞击器一般具有后面或撞击面386和前面或锁定面388。另外，图9提供了软关闭机构382的透视图，该软关闭机构具有安装在活塞杆392的远端上的枢转头390。活塞杆392可沿侧向L在气缸组件394内滑动，该气缸组件为活塞杆392提供阻尼和缩回力。
因此，在操作期间，当外门102朝关闭位置移动时，撞击器380的撞击面388 碰撞枢转头390的第一面396。随着外门102继续朝关闭位置移动，枢转头390相对于活塞杆392枢转，使得枢转头390的第二面398与撞击器380的锁定面/后撞击面386接合。此时，撞击器380的撞击面388和锁定面386被夹在枢转头390的第一面396和第二面398之间，使得外门102与枢转头390一起沿横向L移动。通过这种联动，气缸组件394可以经由活塞杆392用于阻尼外门102的关闭运动。同时，气缸组件394可以将外门102拖动到关闭位置。
当用户希望将外门102移动到打开位置时，用户可以沿滑动轴300的方向拉动外门102的把手108，使得撞击器380的锁定面386拉住枢转头390的第二面398并使活塞杆392在气缸组件394内延伸。在活塞杆392已达到其完全延伸状态后，锁定面386对第二面398的作用力迫使枢转头390远离撞击器380枢转并同时释放撞击器380。活塞杆392可以配置成保持在延伸位置，直到外门102进行后续关闭过程为止。应当理解，所描述的软关闭机构仅为示例性的，并且可以根据附加实施例使用其他软关闭机构。
有利的是，在仅打开外门102来进入框架门的前部时，用户可能只需要沿滑动轴线300的方向拉动把手108，而无需启动闩锁、开关、锁或杠杆。另外或另可选地，在打开框架门105来进入食物储藏室100时，用户可能只需要沿横向T拉动把手108，而无需启动闩锁、开关、锁或杠杆。因此，需要更少的活动部件和复合件来维持正常功能，从而减少了维护和故障可能。
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何装置或系统并且执行所包含的任何方法)。本发明的可授予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。
