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。诸如“内”和“外”的术语是指相对于制冷电器并且特别是限定在其中的食物储存室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”或“底”的术语参考进入制冷电器的用户的视角来使用。例如，用户站在冰箱的前面以打开门体，并且把手伸进食物储存室中以接近其中的物品。
如本文中使用的，近似的用语，诸如“大体”、“大约”或“近似”包括在比所述值大或小百分之十内的值。当在角度或方向的背景下使用时，这种术语包括在比所述角度或方向大或小十度内，例如，“大体竖直”包括在例如顺时针或逆时针的任何方向上与竖向V形成多达十度的角度。
图1和图2提供了根据本发明的一个或多个实施方式的示例性制冷电器100的立体图，其中门体126、128(下面更详细地描述)处于各种位置。制冷电器100限定了竖向V、侧向L以及横向T，各个方向彼此相互垂直。如在图1和图2中可以看到的，制冷电器100包括箱体或壳体120，该箱体或壳体沿着竖向V在顶部101与底部102之间延伸，沿着侧向L在左侧104与右侧106之间延伸，并且沿着横向T在前部108与后部110之间延伸。壳体120限定了用于接收食品以便储存的制冷间室118(图2)。如本文所用，腔室可以被“冷却”，因为腔室可在低于室温(例如，小于大约七十五华氏度(75℉))的温度下操作。
如在图2中可以看到的，制冷间室118在箱体120的顶部101与底部102之间沿着竖向V延伸，并且在箱体120的左侧104与右侧106之间沿着侧向L延伸。制冷间室118还在前部134与后部136之间沿着横向T延伸(图3)。制冷间室118的前部134限定了用于接收食品的开口138。
在一些实施方式中，制冷间室118可以是单个连续室，例如，如图1至图3所示的食物保鲜室118。在这种实施方式中，可以设置单独的冷冻室116。例如，制冷电器100可以包括处于食物保鲜室118下方的冷冻室116，如图1至图3示例。在其他实施方式中，单个制冷间室可以占据箱体120的全部或几乎全部内部容积。在这种实施方式中，单个制冷间室可以被分成在不同温度下可操作的两个或更多个部分。例如，单个制冷间室可以被分成食物保鲜部分和冷冻部分。
如图2所示，各种储存部件可以安装在食物保鲜室118以及诸如第一可变间室300和第二可变间室302的一个或多个门内储存室内，以便于在其中储存食品，如本领域技术人员将理解的。特别地，储存部件可以包括安装在食物保鲜室118和/或可变间室300和302中的一个或两个内的盒202、抽屉204以及搁板206的各种组合。盒202、抽屉204以及搁板206被配置为接收食品(例如，饮料或/或固体食品)，并且可以辅助整理这些食品。
冷藏门体126和128可旋转地安装(例如，铰接)到壳体120的边缘，用于选择性地进入壳体120内的食物保鲜室118。冷藏门体126和128可以在食物保鲜室 118的前部134处或附近安装到壳体120，使得门体126和128在关闭位置(图1)与打开位置(图2)之间旋转。在关闭位置，门体126和128协作地密封地封闭食物保鲜室118。另外，可以设置一个或多个垫圈和其它密封装置，以促进门体126和128与箱体120之间的密封，这些垫圈和其它密封装置未示出，但本领域普通技术人员将理解。在打开位置，门体126和128允许进入食物保鲜室118。在设置单独的冷冻室116的实施方式中，冷冻室116可以沿着竖向V与食物保鲜室118隔开。例如，如图示例，冷冻室116可以设置在食物保鲜室118下方，或者可以设置在食物保鲜室118上方，例如，为顶置式构造。冷冻门体130可以布置为与冷藏门体126和128相邻，例如，在其下方，用于选择性地进入冷冻室116。冷冻门体130可以联接至可滑动地安装在冷冻室116内的冷冻抽屉132(图3)。门体126和128可以大体成镜像，例如，每个门体126或128的总体形状和尺寸可以与另一个门体126或128相同，具有可能的内部变化，诸如下面描述的分配器凹部150。而且，虽然未具体示出，但是门体126和128可独立地旋转，使得例如右门体126可以处于打开位置而左门体128处于关闭位置，或反之。
如在图1中可以看到的，制冷电器100还包括用于分配液态水或冰的分配组件140。分配组件140包括分配器142，该分配器设置在制冷电器100的外部上或或安装到该外部，例如，设置在门体126和128中的一个上，诸如在所示例的示例性实施方式中为左门体128。分配器142包括用于获取冰和液态水的排放口144。例如，冰可以储存在门体126或128之一中的冰盒162(图2)中。被示出为拨片的致动机构146安装在排放口144下方，以便操作分配器142。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分配器142。例如，分配器142可以包括传感器(诸如超声传感器)或按钮，而不是拨片。设置用户界面面板148，以便控制操作模式。例如，用户界面面板148包括多个用户输入(未标记)，诸如水分配按钮和冰分配按钮，这些用户输入用于选择期望的操作模式，诸如碎冰或非碎冰。
排放口144和致动机构146是分配器142的外部零件，并且安装在分配器凹部150中。分配器凹部150设置在冷藏门体126和128中的一个(例如，如在所示例的示例性实施方式中为左门体128)的外侧上，处于便于用户获取冰或水的预定高度处，并且使得用户能够在不需要弯腰并且不需要打开门体126和128的情况下获取冰。在示例性实施方式中，分配器凹部150设置在接近用户的胸部水平的位置处。
冷藏门体126、128在图1中被示出为处于关闭位置。冷藏门体中的一个，例如 如在所示例的示例中为右门体126，可以包括外壳121(图3)，该外壳包括隔热壁125(图3)，该隔热壁在例如右门体126的门体内限定一个或多个可变储存室。在一些实施方式中，例如如图1示例，可以包括可选的隔热中梁304并且可以将其设置在外壳121内。外壳121限定至少一个储存室，例如，在设置有中梁304的实施方式中，由外壳121和竖框304限定的第一可变间室300和第二可变间室302。在没有中梁304的其它实施方式中，可以在门体内限定单个腔室。由此，应当理解，本文对门体内由中梁304分开并限定的多个腔室的描述仅是示例性的，并且本发明、特别是将参照图4至图10更详细描述的冷却系统，不限于两个门内室，并且同样适用于门体内的仅一个腔室或多于两个腔室。
门体，例如右门体126，还可以包括前面板127，该前面板可旋转地安装到外壳121，以选择性地密封地封闭或允许进入第一可变间室300和第二可变间室302。例如，如例如图1所示，当门体126处于关闭位置时，前面板127可以允许进入可变间室300和302。如下面将更详细地描述的，可变间室300和302可以选择性地在各种温度下操作。
在各种实施方式中，食物保鲜室118可在高于水的冰点且低于室温(诸如在大约三十三华氏度(33°F)与大约六十华氏度(60°F)之间)的温度范围内运行。而且以示例的方式，冷冻室116可在包括低于水的冰点(例如小于三十二华氏度(32°F)，诸如在大约三十华氏度(30°F)与大约零华氏度(0°F)之间)的温度范围内运行。例如，食物保鲜室118的温度可以是大约四十华氏度(40°F)或大约四十五华氏度(45°F)，而冷冻室116的温度可以是大约十五华氏度(15°F)或大约二十五华氏度(25°F)。在各种实施方式中，隔热隔板200可以设置在箱体120内，例如在食物保鲜室118与冷冻室116之间(图3)。隔板200可以分开不同的腔室或部分。隔板200可以是水平隔板，例如，隔板200可以沿着垂直于竖向V的平面(例如，由侧向L和横向T限定的平面)延伸。隔热隔板200可以允许或增强食物保鲜室118和冷冻室116在不同温度下的运行。
可变间室300和302可以选择性地例如在第一温度范围和第二温度范围中的一个内作为食物保鲜室或冷冻室运行。例如，第一可变间室300和第二可变间室302可以作为食物保鲜室运行，其中室300和302各自提供在一个或多个上述食物保鲜储存温度范围内的内部温度，例如，在水的冰点以上且在室温以下的温度，诸如在大约三十三华氏度(33°F)与大约六十华氏度(60°F)之间的温度。可变间室300 和302还可选择性地运行以提供低于水的冰点的内部温度，例如在大约三十华氏度(30°F)与大约零华氏度(0°F)之间的温度，如上所述。
可变间室300和302可在不同的温度下操作。例如，当可变间室300和302都作为食物保鲜室运行时，第一可变间室300可在诸如大约五十华氏度(50°F)的相对温暖的温度下运行，例如用于冷却酒，并且第二可变间室可在诸如大约三十七华氏度(37°F)的相对冷的温度下运行，例如用于储存产品。作为另一示例，当可变间室300和302都作为冷冻室运行时，第一可变间室300可以提供软冷冻，例如可在诸如大约二十五华氏度(25°F)的温度下操作，并且第二可变间室可以提供深度冷冻，例如可在诸如大约十五华氏度(15°F)或更低、诸如大约十华氏度(10°F)或更低、诸如大约零华氏度(0°F)或更低的温度下运行。在这种示例中，深度冷冻室还可以提供快速冷冻，例如用于快速冷冻新鲜采摘的产品或鲜肉等。在又一示例中，可变间室300和302中的一个可以在例如高于水的冰点且低于室温的温度范围内作为食物保鲜室运行，如上所述，而可变间室300和302中的另一个可以在例如包括低于水的冰点的温度的温度范围内作为冷冻室运行，如上所述。
本领域普通技术人员将认识到，各个腔室或部分可以由密封制冷系统冷却，使得例如第一可变间室300和第二可变间室302可以通过从密封系统提供冷却空气而在上述温度下或附近运行。例如，一个或多个可变间室可以选择性地在食物保鲜温度或冷冻温度下运行。下面进一步详细描述密封系统的示例性实施方式。
如在图1和图3中最佳看到的，可变间室300和302可以与门体126大体共同延伸。例如，如在图3中看到的，可变间室300、302以及门体126可以沿着竖向V大体共同延伸，例如，可变间室300和302可以共同限定竖直高度(或者在没有中梁304的实施方式中，单个可变间室自身可以限定该高度)，该竖直高度可以与门体126的竖直高度大致相同(除了隔热壁125的厚度之外)。可变间室300、302以及门体126还可以例如根据门体126的方位(例如根据门体126是处于关闭位置还是打开位置)沿着垂直于竖向V的方向(例如，侧向L和横向T中的至少一个)而大体共同延伸。例如，门体126可以在左侧156与右侧158之间延伸，例如当门体126处于关闭位置时沿着侧向L延伸，如图1示例。在这种实施方式中，第一可变间室300和第二可变间室302可以各自从门体126的左侧156延伸到门体126的右侧158，使得可变间室300和302各自沿着垂直于竖向V的方向(例如，当门体126处于关闭位置时为侧向L)与门体126大体共同延伸。
第一可变间室300和第二可变间室302可以竖直地布置在外壳体121内，例如，第一可变间室300在第二可变间室302上方。例如，至少部分地限定可变间室300和302的中梁304可以是水平的，例如，中梁304可以沿着垂直于竖向V的平面(诸如由侧向L和横向T限定的平面)延伸，借此，限定在水平中梁304的相对侧上的可变间室300和302竖直地布置。如上所述，可变间室300和302可以沿着竖向V与门体126大体共同延伸。例如，可变间室300和302可以共同地沿着竖向V从门体126的底部152延伸到门体126的顶部154。如图1和图3示例，第二可变间室302可以沿着竖向V从门体126的底部152延伸到中梁304，并且第一可变间室300可以沿着竖向V从中梁304延伸到门体126的顶部154。
如上所述，前面板127可以选择性地密封地封闭第一可变间室300和第二可变间室302。例如，前面板127可以在提供进入第一可变间室300和第二可变间室302的入径的打开位置(例如，图1)与如例如图3所示的关闭位置之间旋转。当前面板127处于关闭位置时，前面板127对可变间室300和302的密封封闭可以包括中梁304与前面板127之间的密封接合。例如，前面板127可以包括弹性内表面，当前面板127处于关闭位置时，该弹性内表面抵靠中梁304的前边缘。作为另一个示例，也可以或替代地在前面板127和中梁304中的一个上设置本领域通常理解的垫圈或其他密封构件。
经由门体126的前面板127提供进入可变间室300和302的入径可以有利地增加储存在可变间室300和302中的食品的可达性。例如，与当仅设置制冷电器100的单个腔室用于储存新鲜食物或冷冻物品时相比，诸如一袋冷冻蔬菜或一次性饮料容器的较小食品可以储存在可变间室300和302中，以防止或减少这种物品被掩盖在诸如冷冻火鸡、冷冻比萨、一加仑牛奶等较大物品的下方或后面。
现在转向图4，示例了根据本发明的一个或多个实施方式的密封冷却系统400。在图4所示例的示例性实施方式中，制冷电器100包括食物保鲜室118、冷冻室116以及限定在食物保鲜室118的左门体内的单个可变间室300。如将在下面更详细地描述的，密封冷却系统400通常包括：两个或更多个膨胀装置，这些膨胀装置中的一个专用于可变间室300；和多个蒸发器，该多个蒸发器具有用于食物保鲜室118、冷冻室116以及可变间室300中的每一个的专用蒸发器或蒸发器的专用部分。
图4示意性地示例了从冷却系统400到可变间室300以及从可变间室300返回到冷却系统400的气流。特别地，如图4示例的冷却系统400包括：食物保鲜风扇 402，该食物保鲜风扇被配置为将空气从冷却系统400的第一部分推动到食物保鲜室118；门中门风扇404，该门中门风扇被配置为将空气从冷却系统400的第一部分和/或从冷却系统400的第二部分推动到可变间室300；以及冷冻风扇406，该冷冻风扇被配置为将空气从冷却系统400的第三部分推动到冷冻室116。
如上所述，冷却系统400可以包括用于各个室的专用蒸发器或蒸发器的专用部分，使得冷却系统400的第一部分、第二部分以及第三部分包括至少两个蒸发器，其中，冷却系统400的第三部分是冷冻蒸发器，该冷冻蒸发器在一些实施方式中可以被称为第一蒸发器，并且第一部分和第二部分可以是两个单独的附加蒸发器，或者在其它实施方式中可以是第二蒸发器的第一部分和第二部分。
具体返回到图4，冷却系统400可以包括多个管道，以在冷却系统400与室118、116和300之间路由空气。例如，冷却系统400可以包括：门中门供应管道408，该门中门供应管道408从冷却系统400的第一部分或第二部分(在各种实施方式中，冷却系统400的第二部分可以是门中门蒸发器或第二蒸发器的第二部分，这将在下面更详细地描述)延伸到可变间室300；和门中门返回管道410，该门中门返回管道410从可变间室300延伸到冷却系统400的第二部分。门中门风扇404可以被设置并配置为推动空气穿过门中门供应管道408和门中门返回管道410，以通过门中门返回管道410从可变间室300抽吸相对温暖的空气，并且通过门中门供应管道408向可变间室300供应相对冷的空气。管道408和410通常与将空气供应到食物保鲜室118的管道分开。
图5至图10提供了密封冷却系统400的示例性实施方式的图。密封冷却系统400通常包括单个回路，其中工作流体(例如，制冷剂，未具体示例)密封在该单个回路内。例如，各个蒸发器或蒸发器的各个部分都包括在单个闭合的管道回路中，并且在它们之间具有共享的工作流体供应。因此，蒸发器通常顺序地操作，例如，在至少一些实施方式中，冷却空气一次一个地或至多一次两个地按顺序供应到各个室。
密封冷却系统400包括压缩机414和相对于工作流体的流动方向在压缩机414下游的冷凝器416。即，当压缩机414被启动时，压缩机414对单个回路内的工作流体(该流体在操作的该点处通常处于气相)加压，并且工作流体行进穿过冷却系统400到达冷凝器416，在冷凝器416中，工作流体释放热量或热能并且变成液相。然后，通过多通阀418将液相工作流体选择性地引导到多个膨胀装置(例如，在所示 例的示例性实施方式中为毛细管)中的一个。密封冷却系统400还包括相对于工作流体的流动方向在冷凝器416下游的多个蒸发器，例如，工作流体基于多通阀418的位置经由所选的膨胀装置从冷凝器416流到多个蒸发器中的一个或多个蒸发器。
例如，如图5示例，在一些实施方式中，多个蒸发器可以包括冷冻蒸发器412、食物保鲜蒸发器424以及门中门蒸发器426。在一些实施方式中，例如，如图5示例，门中门蒸发器426可以是食物保鲜蒸发器424的下游部分，例如，食物保鲜蒸发器424可以与紧接在食物保鲜蒸发器424下游的门中门蒸发器426直接连接，其中，门中门蒸发器426由来自对应膨胀装置(例如，毛细管422)的入口限定。冷冻蒸发器412可以与冷冻风扇406流体连通，例如，相对于空气流体连通，使得冷冻风扇406将空气从冷冻蒸发器412例如直接地推动到冷冻室116。食物保鲜蒸发器424可以类似地与食物保鲜风扇402流体连通，使得食物保鲜风扇402将空气从食物保鲜蒸发器424推动到食物保鲜室116。门中门蒸发器426可以与门中门风扇404流体连通，使得门中门风扇404将空气从门中门蒸发器418推动到可变间室300。在这种实施方式中，多通阀418可以是三通阀，并且多个毛细管可以包括直接在食物保鲜蒸发器424上游的第一毛细管420和直接在门中门蒸发器426上游的第二毛细管422。蒸发器424、426以及412中的每一个以串行流动顺序连接以完成单个环路，但是，虽然工作流体可以行进穿过多于一个蒸发器或所有蒸发器，哪个(哪些)蒸发器实际上有效不仅取决于多通阀418的位置，而且取决于哪个(哪些)风扇被启动。特别地，关于图5，第一毛细管420可以是食物保鲜毛细管，该食物保鲜毛细管在食物保鲜风扇402启动时向食物保鲜蒸发器424供应工作流体，以用于食物保鲜蒸发器424的操作。第二毛细管422可以是门中门/冷冻毛细管，该毛细管直接向门中门蒸发器426供应工作流体，并且经由门中门蒸发器426向冷冻蒸发器412供应工作流体，其中，当多通阀418被设置为将工作流体的流引导到第二毛细管422时，可以启动门中门蒸发器426和/或冷冻蒸发器412，这取决于门中门风扇404或冷冻风扇406中的哪一个(或两者)被启动。第二毛细管422可以被配置为(例如尺寸被设计为)提供比第一毛细管420更大的压降，从而允许冷却系统400向可变间室300和/或冷冻室116提供比向食物保鲜室118更冷的空气。由此，在该实施方式中，在门中门蒸发器426相对于来自第一毛细管420的工作流体流紧接在食物保鲜蒸发器424的下游并且直接在第二毛细管422的下游的情况下，可以通过将三通阀418设置为经由第一毛细管420和食物保鲜蒸发器424将工作流体供应到门中门 蒸发器426，来将可变间室300冷却至食物保鲜温度，而可以通过将三通阀418设置为将工作流体直接从第二毛细管422供应至门中门蒸发器426来将可变间室300冷却至冷冻温度。
现在转向图6，在一些实施方式中，多个蒸发器可以包括第一蒸发器(冷冻蒸发器)412和第二蒸发器428，并且可以由其构成。在这种实施方式中，食物保鲜风扇402可以与第二蒸发器428的第一部分427或全部第二蒸发器428流体连通，例如直接流体连通，并且门中门风扇404可以与第二蒸发器428的第二部分429或全部第二蒸发器428流体连通，例如直接流体连通。例如，在一些实施方式中，食物保鲜风扇402可以与第二蒸发器428的第一部分427直接流体连通，使得食物保鲜风扇402将空气直接从第二蒸发器428的第一部分427推动到食物保鲜室118，并且门中门风扇404可以与第二蒸发器428的第二部分429直接流体连通，使得门中门风扇404将空气直接从第二蒸发器428的第二部分429推动到可变间室300。在这种实施方式中，门中门毛细管，例如第二毛细管422，可以直接处于食物保鲜蒸发器424的入口的上游，使得第二蒸发器428既是食物保鲜蒸发器(当工作流体从第一毛细管420供应时)又是门中门蒸发器(当工作流体从第二毛细管422供应时)。与图5中示例的食物保鲜蒸发器424和门中门蒸发器426至少部分地由来自第一毛细管420和第二毛细管422的单独入口区分的示例性实施方式相反，在图6所示例的示例性实施方式中，第一毛细管420和第二毛细管422都可以例如经由第二蒸发器428的单个入口在相同点处连接到第二蒸发器428。与图5所示例的实施方式中相同，在图6所示例的示例性实施方式中的第二毛细管422也是冷冻毛细管。另外，当可变间室300以与上述类似的方式设置到例如食物保鲜温度的较暖温度时，可变间室300可以使用图6所示例的实施方式中的第一毛细管420冷却，例如通过将多通阀418设置为将工作流体从冷凝器416引导到第一毛细管420并且启动门中门风扇404来冷却。
现在转向图7，在一些实施方式中，多个膨胀装置可以包括第一毛细管420、第二毛细管422以及第三毛细管423。第三毛细管423可以直接连接到冷冻蒸发器412。由此，在该实施方式中，多通阀418是四通阀，第一毛细管是用于在可变间室300被设置到食物保鲜温度时冷却食物保鲜室118和/或冷却可变间室300的食物保鲜毛细管，第二毛细管422是用于将可变间室300冷却到冷冻温度的专用门中门毛细管，并且第三毛细管423是用于冷却冷冻室116的专用冷冻毛细管。
现在转向图8，示例了密封冷却系统400的另外实施方式，其中，为食物保鲜室 118和可变间室300两者设置单个蒸发器428，例如，如上面关于图6所述，并且其中，第三毛细管423被设置为专用冷冻毛细管，例如，如上面关于图7所述。
在又一些实施方式中，例如，如图9和图10示例，门中门蒸发器426可以是与食物保鲜蒸发器424分离的组件。在这种实施方式中，门中门蒸发器426可以在食物保鲜室118的冷却期间参与或不参与，例如，来自食物保鲜室118的空气可以不接触门中门蒸发器426。在图9中，仅设置了第一毛细管420和第二毛细管422，例如，如上面关于图5所述。在图10中，第一毛细管420是食物保鲜毛细管420，第二毛细管422是门中门毛细管422，并且第三毛细管423是专用冷冻毛细管423，例如，如上面关于图7所述。
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。
