具体实施例
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。在详细描述中，使用数字和字母标记指示附图中的特征。在附图和描述中，相似或类似标记用于指示本公开的相似或类似部分。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，在不脱离本发明范围或精神的情况下，可对本发明进行各种修改和改变。举例来说，作为一个实施例一部分示出或描述的特征，可和另一个实施例一起形成另一个实施例。因此，本发明旨在涵盖落入所附权利要求及其等同范围内的此类修改和改变。
如本文所使用的，术语“第一”、“第二”和“第三”可互换使用，以便将一个部件与另一个部件区分开来，并非旨在指示各个部件的位置或重要性。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品储藏室的制冷电器)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”之类的术语参照用户进入冰箱器具的角度使用。例如，用户站在冰箱前面打开门，将手伸进食品储藏室以获取其中的物品。
如本文中所使用的，表示近似的术语(诸如“大致”或“大约”)包括处于比所述值大或小百分之十范围内的值。当在涉及角度或方向的场景中使用时，这些术语包括处于比所述角度或方向大或小十度的范围内。例如，“大致垂直”包括在任何方向(例如，顺时针方向或逆时针方向)上与垂直度相差十度以内的方向。
如图1至图3所示，示例性制冷电器100具有隔热壳体或箱体120，该隔热壳体或箱体120限定出食品储藏室122。门124可选择性地在处于关闭位置(图1)时密封地封闭食品储藏室122，并在处于打开位置(图2)时提供通往食品储藏室122的途径。门124通过一个或多个铰链126(图2)可旋转地安装到箱体120，以在打开位置和关闭位置之间旋转。
制冷电器100限定出竖直方向V、侧向L和横向T(图3)，竖直方向V、侧向L和横向T中的每一个彼此互相垂直。如图1至图3中所示，箱体或壳体120沿竖直方向V在顶部101和底部102之间延伸，沿侧向L在左侧104和右侧106之间延伸，并沿横向T在前面108(图3)和后面110(图3)之间延伸。如图2和图3中所示，食品储藏室122沿横向T在前部134和后部132之间延伸。食品储藏室122的前部134限定出用于接收食品的开口136。食品储藏室122是用于接收要储藏的食品的冷藏室122。如本文所使用的，腔室可进行“冷却”，因为腔室可在低于室温的温度(例如，小于大约七十五华氏度(75°F)下操作)。本领域普通技术人员将认识到，可以通过密封式制冷系统来冷却食品储藏室122，因此，通过从密封式系统提供冷却的空气，食品储藏室122可以在本文所述的温度或大约在该温度下操作。该等密封式系统的结构和功能是本领域普通技术人员所理解的。为简洁和清楚起见本文不再赘述。
冰箱门124可旋转地安装(例如，铰接)到箱体120的边缘，用于可选择地进入箱体120内的保鲜的食品储藏室122。冰箱门124可以在食品储藏室122的前部134或在其附近安装到箱体120，使得门124在关闭位置(图1)和打开位置(图2)之间移动(例如，经由铰链126旋转)。在图1的关闭位置中，门124密封地封闭食品储藏室122。另外，可设置一个或多个衬垫和其他密封装置(图中未示出但本领域普通技术人员将会理解)，用于促进门124和箱体120之间的密封。在图2的打开位置中，门124允许进入保鲜的食品储藏室122。
例如，如图2和图3所示，可以将各个储藏部件安装在食品储藏室122内，以便如本领域技术人员将理解的，将食品储藏在其中。特别地，储藏部件包括安装在食品储藏室122内 的盒体116、抽屉117和搁架118。盒体116、抽屉117和搁架118配置成用于容纳食品(例如，饮料或固体食品)，并有助于整理这些食品。
如图所示，箱体120限定出单个冷藏室122，用于容纳要储藏的食品。在该示例中，单个冷藏室122是保鲜的食品储藏室122。在一些实施例中，冷藏室是冷冻室，和/或制冷电器100包括一个或多个其他冷藏室，用于接收各种食品并在所需的各种温度下储藏这些食品。例如，制冷电器100可包括一个或多个冷藏室，该冷藏室配置成用于深度冷冻(例如，在大约等于或小于0°F的温度下)储藏，或配置成用于在较高的温度(诸如，大约等于或大于60°F)下，以及在上述示例之间的任何合适温度下对产品或酒类等进行冷藏。在各个示例性实施例中，食品的冷藏室122可根据每种应用的需要或要求，选择地在多种温度下和/或多种温度范围内操作，和/或制冷电器100可包括一个或多个附加腔室，该附加腔室可选择地在任何合适的食品储藏温度下操作。
所示的示例性制冷电器100一般称为单门冰箱或单用途冰箱，又称专用冰箱。然而，本公开的益处适用于其他类型和样式的冰箱，例如底装型冰箱、顶装型冰箱、并排式冰箱或冷冻电器。因此，本文阐述的描述仅用于说明，并非旨在在任何方面对特定的冷藏室配置构成限制。另外，本文所述的开门器能够用于其他类型的电器(诸如，微波炉电器、洗衣机/烘干机电器等)中，和/或可能需要所公开特征的其他场景中。
如图2和图3中所示，制冷电器100可包括开门器200。开门器200可设置在箱体120中。例如，开门器200可以位于箱体120中靠近箱体120前面108和食品储藏室122的开口136的位置。在所示的示例性实施例中，开门器200沿竖直方向V位于靠近箱体120顶部101的位置，一般沿侧向L居中。即示例性开门器200(如在图2中最佳可见)位于或大致位于箱体120和/或食品储藏室122的开口136的侧向中点。在其他实施例中，开门器200位于箱体120内的其他位置，诸如沿竖直方向V位于底部102附近。在一些实施例中，将开门器200沿侧向L居中，能够有利于灵活地对门124进行安装。例如，所示制冷电器100包括安装在右侧106的门124。在其他实施例中，门124(例如，通过铰链126)可以在左侧104或靠近左侧104安装到箱体120上。在开门器200沿侧向L居中的实施例中，在将门124安装到左侧104或右侧106中的任一侧时，开门器200将向门124施加大致相同的打开力。例如，当门124围绕铰链126旋转时，施加到门124上的力臂或杠杆作用将大致相同。
现在转到图4，开门器200限定出竖直方向V，侧向L和横向T。竖值方向V、侧向L和横向T相互垂直。开门器200可包括外壳202，该外壳202沿横向T从后部203延伸到前部201。开门器200一般定向并安装在制冷电器100中，使得相应的方向大致被对齐，例如， 彼此相差十度。例如，开门器200可以设置(例如，安装)在箱体120内，使得由开门器200限定的竖直方向V与由制冷电器100限定的竖直方向V大致相同，由开门器200限定的侧向L与制冷电器100限定的侧向L大致相同，由开门器200限定的横向T与制冷电器100限定的横向T大致相同。另外，外壳202的前部201沿横向T大致与箱体120的前面108接近或对齐，而与箱体120的前面108相比，外壳202的后部203相应地更靠近箱体120的后面110。
开门器200的外壳202可例如经由机械紧固件牢固地安装到箱体120上，该机械紧固件延伸穿过外壳202上的安装法兰216中的孔214。外壳202可牢固地安装到箱体120上，因为在制冷电器100(包括其开门器200)的常规操作和预期操作期间，外壳202无法相对于箱体120移动。开门器200还包括位于外壳202内的内壳204，该内壳204能够相对于外壳202移动。开门器200可包括指状件206，该指状件206包括前部或杆部210，以及螺纹后部或动力螺杆部208。指状件206(例如，其杆部210)可以穿过内壳204和外壳202朝向制冷电器100的门124延伸，如图3所示。在备选实施例中，整个指状件206可带有螺纹，或者，前部210可以带有螺纹而后部208不带有螺纹。如图3所示，开门器200处于零位。图3示出了开门器200相对于制冷电器100的零位，图7提供了开门器200处于零位的图示，其中图7示出了开门器200的其他示例性细节。与图3和图7中的零位相比，图4至图6中示出了处于伸出位置的开门器200，其中指状件206从内壳204和外壳202充分延伸，以促使门124远离箱体120(例如，远离图3所示的关闭位置，并朝向图2所示的打开位置)。如本领域技术人员将理解的，铰链126可配置成在朝向打开位置具有足够动量的情况下，使门124完全移动到图2所示的打开位置。当指状件206移动到伸出位置时，该足够的动量可以通过开门器200传递到门124。如图5至图8中所示和以下参照图8更详细描述的，开门器200可包括电动机226，该电动机226可操作地与指状件206连通。例如，电动机226可以配置成使指状件206在零位和伸出位置之间移动。
如图4至图7中所示，在零位和伸出位置这两个位置中，内壳204通过偏压元件224在外壳202内沿横向T例如朝向外壳202的前部201偏置。偏压元件224可以沿横向T在外壳202和内壳204之间(例如，从外壳202到内壳204)延伸。在一些实施例中，偏压元件224可以是如图所示的螺旋弹簧224。例如，如图5和图6所示，螺旋弹簧224可以在螺旋弹簧224的一端围绕外壳202上的外旋钮228周向延伸，并可在螺旋弹簧224的另一端(相对端)围绕内壳204上的内旋钮230周向延伸。如上所述，当开门器200处于图4至图6中所示的伸出位置时，门124可处于打开位置；当开门器200处于零位时，门124可处于关闭位置。当门124处于关闭位置且开门器200处于零位时，指状件206将与门124的内表 面125接触，如上所述和如图3所示。如图7中所示，开门器200包括一个或多个传感器302和/或304，该传感器配置成检测内壳204和外壳202之间的相对移动。推动门124可以使内壳204相对于外壳202移动。例如，当门124处于关闭位置且开门器200处于零位时，推动门124后，可以经由门124的内表面125从门124传递到指状件206，然后从指状件206传递到内壳204，致使内壳204沿横向T向后移动，例如，朝向箱体120的内部和/或外壳202的后部203向内移动。这种移动可以通过一个或多个传感器302和/或304进行感测或检测，并且传感器302和/或304能够可操作地与电动机226连通。因此，传感器302和/或304可配置成当传感器302/304检测到内壳202沿横向T从开门器200的零位、朝向箱体120的后部110和/或外壳203的后部移动时，向电动机226传输信号。电动机226继而配置成从传感器302/304接收信号，以响应于来自传感器302/304的信号而启动；当电动机226启动时，使指状件206沿横向T朝向箱体120的前部108、和/或外壳202的前部201移动。
当电动机226未启动时，指状件206和内壳204一般锁定在一起。例如，响应于作用在指状件206或内壳204中任一个上的横向取向力，指状件206或内壳204沿横向T一起移动。因此，偏压元件224可配置成将内壳204和指状件206朝向外壳202的前部201偏置。
在一些示例性实施例中，传感器可以是线性传感器302。例如，线性传感器302可以与弹簧224平行设置，如图7所示。线性传感器302可以是线性编码器或电位计，该线性编码器或电位计配置成感测和/或响应线性传感器302的长度变化。其中线性传感器302的长度在外壳202和内壳204之间沿横向T限定，如图7所示。在其他示例性实施例中，传感器可以是任何合适的位置传感器，诸如例如图7中示出的霍尔效应传感器304。如上所述，可以设置一个或多个传感器。因此，在附加的示例性实施例中，可以同时设置线性传感器302和霍尔效应传感器304。
必须克服螺旋弹簧224的偏置力，以便使内壳204相对于外壳202移动得足够远，从而使传感器302和/或304跳闸并启动电动机226。因此，螺旋弹簧224可以有利地防止或最大程度地减少意外启动开门器200的情况。例如，当用户(或宠物等)轻轻擦到门124时，由于通过偏压元件(例如，螺旋弹簧224)抵抗了内壳202的相对向内运动，可能不会触发开门器200。作为另一个示例，偏压元件(例如，螺旋弹簧224)可以保护开门器200免受门124的碰撞。在一些实施例中，例如，如图4至图6中所示，螺旋弹簧224可设置并配置成用于压缩。例如，当内壳204相对于外壳202朝向外壳202的后部203移动时，将会压缩螺旋弹簧224。在其他实施例中，螺旋弹簧224可设置并配置成用于张紧。例如，螺旋弹簧224可以在外壳的前部201沿横向T从外壳202向内壳204延伸，使得当内壳204相对 于外壳202朝向外壳202的后部203移动时，将会拉伸螺旋弹簧224并使其处于张紧状态。
在操作中，在门124处于关闭位置且开门器200处于零位的情况下，当用户推动门124时，推力传递到内壳204，致使内壳204相对于外壳202沿横向T朝向箱体120的后部110和/或朝向外壳202的后部203移动。传感器302/304检测到该相对移动，并传输信号至电动机226。电动机226随后启动并使指状件206从零位移动到伸出位置。当门124处于关闭位置且指状件206从零位移动到伸出位置时，指状件206的这种移动克服了门124的惯性并将门124推向打开位置。铰链126配置成使得一旦门124开始朝向打开位置摆动，例如响应于开门器200的指状件206沿横向T向外/向前地向内表面125推动，门124的动量将会把门124完全带到打开位置。因此，在启动开门器200(例如，其电动机226)后，开门器200将处于伸出位置，门124将处于打开位置。从这一点来说，开门器200可进一步配置成自动缩回，例如，在预定时间段之后，电动机226可以在相反方向上启动，以使指状件206返回到零位。
在另一个示例中，电动机226可配置成响应于检测到的第一次推动，启动指状件206并使其从零位移动到伸出位置。电动机226还可进一步配置成响应于随后(例如，第二次或紧随其后)检测到的推动而在相反方向上启动，以使指状件206从伸出位置移动到零位。在这样的实施例中，开门器200也可以是闭门器。例如，指状件206可包括尖端212，该尖端212与门124的内表面125接合。例如，尖端212可以与门124的内表面125磁性接合。例如，在一些实施例中，磁体可以在门124上安装到内表面125或内表面125的正下方，以便与指状件206磁性接合，该指状件206可以由铁质材料构成。此外，在一些实施例中，尖端212可以具有磁性，门124可包括铁质材料(例如，门124本身或内表面125上的铁质接触板包括铁质材料)，以便与尖端212磁性接合。在这样的实施例中，在开门器200处于伸出位置的情况下，当门124朝向关闭位置旋转时，门124的内表面125可以接触指状件206的尖端212，从而启动开门器200，使得电动机226将指状件206从伸出位置移动到零位。这种移动可以通过门124和指状件206之间的磁性接合而传递到门124上，使得响应于在指状件206处于伸出位置时门124向内摆动而接触指状件206(例如，如上所述的随后推动可以是向内摆动的门124撞击伸出的指状件206所致)，指状件206从伸出位置移动到零位，在这种情况下，指状件206将门124磁性拉动到关闭位置。
在一些实施例中，开门器200还可包括锁定到指状件206上的平移载架218。在一些实施例中，可靠近外壳202的前部201设置前限位开关220，该前限位开关220可操作地与电动机226连通。在这样的实施例中，前限位开关200可配置成当拨动前限位开关220时停用电动机226。例如，如图4至图6所示，当平移载架218与前限位开关220接触时，可以拨 动前限位开关220。因此，伸出位置可以是完全伸出的位置(与中间或部分伸出位置不同)，这是因为指状件206可以沿横向T行进的最大向前距离由前限位开关平移载架218接触220的点限定。应当理解，虽然在所示的示例性实施例中将平移载架218描绘成包括多个不同的部分，但是平移载架218并不限于这种构造。在一些实施例中，平移载架218也可以包括单个整体件。
由此可见，通过将图5和图6与图7相比较，当指状件206在零位和伸出位置之间移动时(例如，当指状件206由电动机226驱动时)，指状件206相对于内壳204和外壳202移动。如在图8中最佳可见，电动机226包括驱动轴232和安装在驱动轴232上的驱动齿轮234。驱动齿轮234上可以具有齿部(未具体示出但本领域技术人员可以很好地理解)，该齿部与正齿轮236的外齿部(正齿轮236的该齿部可以在例如图4中可看到)啮合。如在图8中可见，电动机226可以减速，这是因为驱动齿轮234的外径可以小于正齿轮236的外径。正齿轮236可以具有螺纹(例如，其上包括内螺纹)，并可与指形件206的动力螺杆部分208上的外螺纹209接合。因此，电动机226可以操作成在启动时使驱动轴232在第一方向上旋转，并且可以操作成使驱动齿轮234和正齿轮236转动，而正齿轮236继而使指状件206的动力螺杆部分208旋转，从而将指状件206从零位移动到伸出位置。电动机226还可以在相反方向上操作，例如使驱动轴232在与第一方向相反的第二方向上旋转，使得驱动齿轮234和正齿轮236运转以缩回指状件206，例如将指状件206从伸出位置移动到零位。根据前述内容可知，指状件206(例如，其动力螺杆部分208)可围绕横向T旋转，同时沿横向T平移，以便指状件206在电动机226启动时在零位和伸出位置之间移动。
在一些实施例中，例如，如图8所示，电动机226可以位于内壳204内的第一隔间中，并可设置第二隔间227。在至少一些实施例中，可以在第二隔间227中设置第二电动机226。通过设置第二电动机226，可以向开门器200提供额外动力(例如，用于打开/关闭门124)，同时最大限度地减小开门器200的整体尺寸(诸如，在竖直方向V上的整体尺寸)。
在一些实施例中，开门器200还可以包括后限位开关222。与上述前限位开关220相似，后限位开关222可在拨动时(例如，与平移载架218接触时)停用电动机226或使电动机226反转。
本书面描述使用示例来公开本发明(包括最佳方式)，可使本领域技术人员实践本发明，包括制造和使用任何设备或系统以及执行任何包含的方法。本发明的可授予专利权的范围由权利要求限定，并包括本领域技术人员想到的其他示例。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，或此类其他示例包括与权利要求的字面语言没有实质区别的等效结构元件，则此类其他示例在权利要求的范围内。
