背景技术
制冷电器(诸如冰箱和/或冷冻电器)通常包括限定制冷间室的箱体。由此，多种食品可以储存在制冷间室内。制冷间室相对于环境大气的低温有助于增加储存在制冷间室内的食品的保质期。
更具体地，某些制冷电器利用密封系统来冷却制冷间室。典型的密封系统包括蒸发器和风扇，其中风扇生成穿过蒸发器的空气流并冷却该空气流。然后，冷却空气通过开口供应到制冷间室中，以将制冷间室维持在期望的温度。来自制冷间室的空气通过回风管道返回，以在制冷电器的运行期间由密封系统重新冷却，这将制冷间室维持在期望的温度。
由此，某些制冷电器可以包括一个或多个出风口，该一个或多个出风口限定进入制冷间室的开口，以允许适当的空气流动。然而，在制冷电器的运行期间，过量的水汽和/或霜可能累积在出风口中和周围。随着水汽和/霜继续累积，出风口无法如设计的那样运行。此外，如果出风口堵塞，则气流的温度将降低，并且可能出现湿度问题。
因此，具有被构造为减少在电器的运行期间水汽和/或霜累积的量的特征的用于制冷电器的改进的出风口将是有用的。

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。
现在参见附图，图1提供了根据本发明的示例性实施方式的制冷电器100的立体图。制冷电器100包括箱体或壳体102，该箱体或壳体沿着竖向V在顶部104与底部106之间延伸，沿着侧向L在第一侧108与第二侧110之间延伸，并且沿着横向T在前侧112与后侧114之间延伸。竖向V、侧向L以及横向T中的每一个彼此互相垂直。
壳体102具有用于接收食品以便储存的制冷间室。特别地，壳体102具有设置在壳体102的顶部104处或与其相邻设置的食物保鲜室122和设置在壳体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，顶置式制冷电器或对开门式制冷电器。因此，本文阐述的描述仅出于例示性目的，而无意于在任何方面限制任何特定的制冷室构造。
冷藏门体128可旋转地铰接到壳体102的边缘，以便可选择性地进入食物保鲜室122。类似地，冷冻门体130可旋转地铰接到壳体102的边缘，以便选择性地打开冷冻室124。为了防止冷空气泄漏，冷藏门体128、冷冻门体130和/或壳体102可以在门体128、130与壳体102接合的面处设置有一个或多个密封机构(例如，橡胶封条，未示出)。如图1所示的冷藏门体128和冷冻门体130为处于关闭状态，并且在图2中被示出为处于打开状态。应当理解，具有不同样式、位置或构造的门体是可能的，并且在本发明的范围内。
制冷电器100还可以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，该分配器设置或者安装在制冷电器100的外部，例如，在冷藏门体128中的一个上。分配器134包括用于获取冰和液态水的排放口136。被示出为拨片的致动机构138安装在排放口136下方，以便操作分配器134。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134。例如，分配器134可以包括传感器(诸如超声传感器)或按钮，而不是拨片。设置控制面板140，以便控制操作模式。例如，控制面板140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136和致动机构138是分配器134的外部零件，并且安装在分配器凹部142中。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或水，并且使得用户能够在不需要弯腰的情况下且在不需要打开冷藏门体128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。根据示例性实施方式，分配组件132可以从制冰机152接收冰，该制冰机布置在食物保鲜室122的子间室中。
现在参见图2，提供了制冷电器100的前视图，其中冷藏门体128和冷冻门体130被示出为处于打开位置。根据所示例的实施方式，如本领域技术人员将理解的，各种储存部件安装在食物保鲜室122和冷冻室124内，以促进食品在其中的储存。特别地，储存部件包括安装在食物保鲜室122或冷冻室124内的盒146、抽屉148以及层架150。盒146、抽屉148以及层架150用于放置食品(例如，饮料或/或固体食品)，并且可以辅助整理这些食品。作为示例，抽屉148可以收纳新鲜食品(例如，蔬菜、水果或/或奶酪)，并且增加这种新鲜食品的使用寿命。
现在参见图3和图4，将根据本发明的示例性实施方式描述冷冻室124。如图示例，箱体或壳体102包括限定有冷冻室124的内胆160。例如，内胆160可以是连接到壳体102内部的注塑门胆。在壳体102与内胆160之间可以存在诸如可膨胀泡沫的隔热材料(未示出)，以便辅助使冷冻室124隔热。例如，在组装壳体102和内胆160之后，可以将聚氨酯泡沫注入壳体102与内胆160之间的空腔中。冷冻门体130可以类似方式构造，以辅助使冷冻室124隔热。
冷冻室124通常沿着侧向L在左壁162与右壁164之间延伸，沿着竖向V在底壁166与顶壁168之间延伸，并且沿着横向T在室开口170与后壁172之间延伸。制冷电器100还可以包括中梁176，该中梁设置在冷冻室124内，以将冷冻室124分为第一冷冻间室180和第二冷冻间室182。根据所示例的实施方式，中梁176通常沿着横向T在室开口170与后壁172之间延伸，并且沿着竖向V在底壁166与顶壁168之间延伸。这样，中梁176通常是竖直定向的，并将冷冻室124分成两个尺寸相等的间室180、182。
为了限制第一冷冻间室180与第二冷冻间室182之间的热传递，中梁176通常可以由诸如泡沫的隔热材料形成。另外，为了提供结构支撑，刚性注塑内胆或金属框架可以包围隔热泡沫。根据另一示例性实施方式，中梁176可以是真空隔热板，或者可以包含真空隔热板，以使第一冷冻间室180与第二冷冻间室182之间的热传递最小化。根据示例性实施方式，内胆160和/或中梁176可以包括诸如引导件或滑动件的特征，例如以确保中梁176在内胆160内的正确设置、安装和密封。
诸如橡胶或泡沫封条(未示出)的密封件可以围绕中梁176的边缘设置，在该边缘处，密封件接触内胆160和/或冷冻门体130。另外，中梁176可被形成为具有与内胆160相同的形状，使得在安装中梁176时形成紧密的密封。然而，如下面进一步描述的，中梁176可进一步包括允许制冷系统部件穿过中梁176所需的凹部、孔口或通道。
根据示例性实施方式，中梁176是可拆卸的，使得内胆160可以形成为与传统的单间室冷冻室相同的形状。这样，可以使用相同的工具来形成两种制冷电器，从而降低成本。尽管中梁176被示例为竖直地延伸穿过冷冻室124的中部，但是应当理解，中梁176可以以任何合适的方式来定尺、设置和构造，以在冷冻室124内形成分离的冷冻子间室。
现在参见图5，将描述可用于冷却冷冻室124的示例性制冷系统190的示意图。应当理解，制冷系统190仅为了说明的目的而提供。由此，也可以采用其它类型的 制冷系统，包括例如斯特林循环、热电元件等。制冷系统190通常用于执行蒸汽压缩循环，该循环用于冷却制冷电器100内的空气，例如食物保鲜室122和冷冻室124内的空气。如图所示，制冷系统190包括串联连接并填充有制冷剂的压缩机192、冷凝器194、膨胀装置196以及蒸发器198。
在制冷系统190的运行期间，气态制冷剂流入压缩机192中，该压缩机运行为增大制冷剂的压力。制冷剂的压缩升高其温度，通过气态制冷剂穿过冷凝器194使该温度降低。在冷凝器194内，进行与周围空气的热交换，以便冷却制冷剂并使得制冷剂冷凝为液态。
膨胀装置(例如，阀、毛细管或其他限制装置)196接收来自冷凝器194的液态制冷剂。液态制冷剂从膨胀装置196进入蒸发器198。在离开膨胀装置196并进入蒸发器198时，液态制冷剂的压力下降并蒸发。由于制冷剂的压降和相变，蒸发器198相对于制冷电器100的食物保鲜室122和冷冻室124是凉的。由此，产生冷却空气并且对制冷电器100的食物保鲜室122和冷冻室124进行制冷。由此，蒸发器198是一种热交换器，该热交换器将热量从经过蒸发器198的空气传递到流过蒸发器198的制冷剂。
应当理解，所示例的制冷系统190仅仅是制冷系统190的一个示例性构造，该制冷系统可以包括额外的部件(例如，一个或多个额外的蒸发器、压缩机、膨胀装置和/或冷凝器)。作为示例，制冷系统190可以包括两个蒸发器。作为另外示例，制冷系统190还可包括储液器199，该储液器设置在蒸发器198的下游，并且可以被构造为在将来自制冷剂流的冷凝制冷剂传递到压缩机192之前收集它。
再次一般参见图3和图4，蒸发器198可以设置为与内胆160的后壁172相邻。制冷系统190的其余部件通常位于制冷电器100的机械室200内。管道202可将制冷剂通过液体入口传递到冷冻室124中到达蒸发器198，并且可将制冷剂从蒸发器198通过液体出口从冷冻室124中传递出去。
根据所示例的实施方式，蒸发器198可包括第一蒸发器部分204和第二蒸发器部分206。第一蒸发器部分204和第二蒸发器部分206串联连接，使得制冷剂在通过第二蒸发器部分206之前首先通过第一蒸发器部分204。更具体地，根据所示例的实施方式，第一蒸发器部分204和第二蒸发器部分206通过过渡管208连接。过渡管208可以是单独的连接管道或形成蒸发器198的管的一部分。如图示例，第一蒸发器部分204设置在第一冷冻间室180内，并且第二蒸发器部分206设置在第二冷冻间室182内。
蒸发器盖通常放置在蒸发器198上方，以在内胆160内形成蒸发室。例如，如图示例，第一蒸发器盖220设置在第一冷冻间室180内的蒸发器198上，或更具体地，在第一蒸发器部分204上。这样，内胆160、中梁176和第一蒸发器盖220形成容纳第一蒸发器部分204的第一蒸发室222。类似地，第二蒸发器盖224设置在第二冷冻间室182内的蒸发器198上，或更具体地，在第二蒸发器部分206上。这样，内胆160、中梁176和第二蒸发器盖224形成容纳第二蒸发器部分206的第二蒸发室226。
蒸发室222、226通常包括一个或多个回风管道和送风管道，以允许空气循环进出第一冷冻间室180和第二冷冻间室182。例如，如图4所示，第一蒸发器盖220设置有用于允许空气进入第一蒸发室222的第一回风管道230和用于将空气从第一蒸发室222排出到第一冷冻间室180的第一送风管道232。类似地，第二蒸发器盖224限定了用于允许空气进入第二蒸发室226的第二回风管道234和用于将空气从第二蒸发室226排出到第二冷冻间室182的第二送风管道236。
根据所示例的实施方式，第一回风管道230和第二回风管道234设置为接近冷冻室124的底部(例如接近底壁166)，并且第一送风管道232和第二送风管道236设置为接近冷冻室124的顶部(例如接近顶壁168)。然而，应当理解，根据可选实施方式，用于在蒸发室与冷冻间室之间提供流体连通的任何其它合适的装置都是可能的，并且在本发明的范围内。
例如，如图6和图7所示，根据本发明示例了独立的冷冻电器250。特别地，如图所示，独立的冷冻电器250可以与图1至图5中描述的冷冻室124类似地构造和操作。例如，如图所示，独立冷冻电器250可以包括具有形成制冷间室254的多个壁的箱体252。而且，如图6所示，独立冷冻电器250还可以包括门体256，该门体连接到箱体252，以选择性地打开或关闭制冷间室254。另外，如图所示，独立冷冻电器250可以包括制冷系统258，该制冷系统用于通过延伸穿过制冷间室254的壁262的管道260向制冷间室254供应冷空气。由此，如图所示，独立冷冻电器250还包括至少一个设置在管道260的一端并安装到壁262的出风口264。例如，如图所示，独立冷冻电器250包括三个出风口264。在另外的实施方式中，应当理解，独立冷冻电器250可以包括多于三个的出风口或少于三个的出风口。
现在参见图8至图16，示例了根据本发明的出风口264的不同实施方式的各种视图。如图所示，出风口264通常具有限定有开口268的主体266，冷空气在制冷电器100的运行期间通过该开口排出。此外，如图所示，出风口264的主体266进一 步具有外边缘270，该外边缘限定了出风口264的主体的最外面。在特定实施方式中，如图8至图16所示，出风口264的外边缘270可包括四个边缘，四个边缘包括两个侧边缘278、280、上边缘282和下边缘284。
因此，如图9、图12、图14和图16中特别示出的，出风口264的主体266的外边缘270还包括至少一个突变处272。由此，当安装到制冷电器100的壁262时，突变处272在主体266与壁262之间形成至少一个气流通道274，以减少箱体252中的水汽。更具体地，如图所示，突变处272可以包括多个肋276或突起，这些肋或突起在制冷电器100的主体266与壁262之间形成多个气流通道274。在这样的实施方式中，多个肋276可具有任何合适的横截面形状。例如，横截面形状可以是正方形、矩形、梯形、三角形、半椭圆形(诸如半圆形或半椭圆形)或类似形状。在特定实施方式中，如图9和图12所示，多个肋276的横截面形状大致为矩形。在另一个实施方式中，如图16所示，多个肋276的横截面形状大致为梯形。
而且，肋276可具有任何合适的尺寸和/或间距，以提供通过气流通道274的期望流速。例如，如图8至图14所示，气流通道274的尺寸有宽有窄(即，出风口264的主体266的侧面的大部分包含气流通道274而不是肋276)。相比之下，如图15和图16所示，气流通道274的尺寸/宽度可以大致等于肋276的宽度。
在另外的实施方式中，如图8至图12所示，主体266的四个边缘278、280、282、284中的每一个可以设置有至少一个肋276。在这样的实施方式中，两个侧边缘278、280可以各自包括两个肋276，以在主体266与壁262之间形成一个气流通道274。
在另外的实施方式中，如图9中特别地示出的，主体266的上边缘282可包括四个肋276，以在主体与壁262之间形成三个气流通道274中。此外，如图10所示，下边缘284可包括两个端肋286，该两个端肋限定单个长的气流通道274。另外，如图9、图10和图14所示，端肋286可以位于出风口264的主体266的拐角处，并且可以是弯曲的肋286。在这样的实施方式中，如图所示，各个弯曲肋286可以由在上边缘282和下边缘284中的一个上的端肋和两个侧边缘278、280中的一个的端肋形成。
在另一实施方式中，如图10和图11所示，气流通道274的表面288可具有锥角或拔模角，以降低从出风口264的前侧(例如，如图11所示)观察气流通道274的可见性。
在又一些实施方式中，如图8至图10和图12至图13所示，出风口264的主体266可包括一个或多个卡持构件290，例如用于将出风口264固定在制冷电器100的 壁262中的管道的端部处。特别地，如图13所示，卡持构件290可以包括用于接收壁262并将出风口264保持在适当位置的槽口292。
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系统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。
