Description

能够改善机械室内空气循环的冰箱 技术领域
本发明涉及冰箱或电器领域，尤其涉及一种能够改善机械室内空气循环的冰箱。
背景技术
冰箱或电器一般包括箱体，所述箱体形成有用于储藏食物或其它易腐物品的冷藏室，例如保鲜室或冷冻室。另外，冰箱一般还包括可转动地铰接在箱体上的门，以便选择性地取用冷藏室中储藏的食物。通常，冰箱包括用以安装压缩机或冷凝器的机械室。
常常可以看到，传统冰箱从安装的墙壁或橱柜伸出来。为了解决该问题，将某些冰箱(通常称作嵌入式冰箱)构造成安装在橱柜中，使冰箱看起来是厨房或房间的组成部分。尽管这样很美观，但可能会引起其它问题。机械室通常需垂直叠放在冷藏室下方。因此，很难使空气在机械室中循环以进行热交换。进风口和出风口通常必须彼此相邻设置，例如在冰箱的正面。继而，很难避免进入机械室的进风气流与来自机械室的输出气流混合。
已有设备尝试通过在前面或侧面提供自机械室向外(即，向用户)延伸的壁板或面板来解决上述空气循环问题。类似地，还有设置自门向机械室延伸(当门关闭时)的壁板的方案。但是，在机械室的前面设置不连续的元件或结构通常会导致不美观。这样的构造还可能产生影响用户使用的外表面，如钩住织物，沉积灰尘，甚至绊住从设备前面经过的用户。
因此，业内急需对冰箱或电器中的空气循环结构做进一步设计，特别是提供一种具有一个或多个特征的冰箱或电器，能够防止进出机械室的气流发生混合，同时仍提供连续或不间断的前表面。

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，而不是对其进行限制。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。
如本文中所使用，“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。“上游”和“下游”是指相对于流体通路中流体流动的相对流动方向。例如，“上游”是指流体从中流出的流动方向，而“下游”是指流体流入其中的流动方向。“内”和“外”等词语是指相对于冰箱的内部和外部的相对方向。例如，“内”或“向内”是指朝向冰箱电器内部的方向。“左”、“右”、“前”、“向前”、“后”、“向后”、“顶部”或“底部”等词语是参照用户接近冰箱电器的视角。例如，用户站在冰箱前面打开冰箱门，并伸手进冷藏室内取用其中的食物。
现参考图1至图3，图中提供了示范性冰箱100的多个立体图。根据本发明内容的一个实施例的冰箱100界定了竖向V、侧向L和横向T(图3)，每个方向彼此相互垂直。可以看出，冰箱电器100包括壳体或箱体110，所述壳体或箱体110沿着竖向V在顶部112和底部114之间延伸，沿着侧向L在左侧(例如，第一侧面)116和右侧(例如，第二侧面)118之间延伸，并沿着横向T在前端或前侧120(图3)和后端或后侧122(图3)之间延伸。
箱体110界定了一个或多个冷藏室128(例如，保鲜室或冷冻室)，用于容纳要储藏的食物。具体来讲，冷藏室128设在左侧116和右侧118之间。在一些实施例中，冷藏室128设在箱体110的顶部112或靠近顶部112设置。尽管如此，应当理解，除非另外指出，否则冷藏室128可设在冰箱100内的任何合适的位置。此外，尽管示出了单个冷藏室128，但是应当理解，替代实施例可包括任何合适数量或形状的冷藏室128(例如，保持在单独的或离散的温度下)。
冰箱100还包括可转动地安装在箱体110上的一个或多个冰箱门124，例如，使得冰箱门124允许选择性地进入冷藏室128的至少一个部位。在一些实施例中，冰箱门124在箱体110的一侧(例如，右侧118)可转动地安装在箱体110上。把手130可设在冰箱门124上，以便于将门124在关闭位置(图1)和打开位置(图2)之间移动，其中关闭位置限制进入 冷藏室128(例如，通过跨越冷藏室128延伸)，打开位置允许进入冷藏室128(例如，通过与冷藏室128分隔开)。
如图2所示，可在保鲜100内安装各种储藏组件，以便于食物的储藏。在某些实施例中，储藏组件包括门搁架132、抽屉134和搁架136，所述储藏组件安装在冷藏室128内。门搁架132、抽屉134和搁架136构造成用于容纳食物(例如，饮料或固体食物)，并且有助于整理这些食物。
通常，提供密封系统来冷却冷藏室128内的空气(例如，通过将制冷剂循环作为制冷循环的至少一部分)。例如，可将密封系统的一个或多个组件(例如，压缩机238或冷凝器240)装在或设在由箱体110界定的机械室210(例如，在冷藏室128的下面或正下方)的内部。在一些实施例中，用门124(例如，处于关闭位置的)选择性地盖住或封住机械室210。特别地，机械室210可设在门124的后方。相对于竖向V，可在门124的底部边缘126的上方设置机械室210的一个或多个开口(例如，侧向孔224)。这样，门124关上时，可将一个或多个(例如，所有的)侧向孔224隐藏起来，使站在组件100前面的用户无法看到这些孔。
特别参考图3至图6，图中提供了机械室210的各种视图(例如，箱体110的底部114)。在某些实施例中，机械室210从左侧116到右侧118沿侧向L横跨箱体110。在另外的或替代性实施例中，机械室210从前端120到后端122沿横向T横跨箱体110。
通常，机械室210包括进风口212(例如，设在前端120)，用于允许空气进入机械室210和出风口214(例如，设在前端120)，用于允许空气离开机械室210。在某些实施例中，进风口212和出风口214在侧向上彼此靠近设置。例如，进风口212和出风口214可沿侧向设置在相远离的位置处。在一些实施例中，进风口212设在右侧118的近端(即，左侧116的远端)，而出风口214设在左侧116的近端(即，右侧118的远端)。在机械室210内，机械室210包括一个或多个空气通道(例如，进风通道216、218或输出通道220)，以引导空气从进风口212到出风口214流过机械室210。
所述百叶板222安装箱体110的机械室210前面。特别地，百叶板222可设在至少部分地限定空气入口212和空气出口214的开口的前面(例如，图2中冷藏室128的下面)。在一些实施例中，百叶板222从左侧116到右侧118沿着侧向L延伸。在百叶板222的至少一 部分上，界定了多个侧向孔224。如图所示，所述多个侧向孔224的第一端226到第二端228沿着侧向L延伸。在某些实施例中，侧向孔224在第一端226和第二端228之间不间断或没有任何不连续的中断元件。因此，多个所述侧向孔224可呈现为连续的线状或开口(例如，图2中冰箱100的底部)。此外，侧向孔224可呈现为在冷藏室128下面的唯一开口。每个侧向孔224可以彼此间隔开(例如，在竖向上)。在一些这种实施例中，其中一个或多个侧向孔224彼此平行。
当安装到箱体110上时，所述多个侧向孔224延伸越过进风口212和出风口214。进风口212和出风口214可以由百叶板222限制或以其他方式进一步界定。
侧向孔224通常从机械室210沿横向T延伸到冰箱100的前端120。在可选实施例中，其中一个或多个侧向孔224以与横向T成一定角度(例如，不平行)的方式延伸。例如，一个或多个侧向孔224可与横向T成负角从机械室210指向下方。这样，从机械室210引导流过侧向孔224的空气可从机械室210向前流动并朝向地面(例如，远离冷藏室128)。
回到图1和图2，如上所述，门124可设在机械室210的前面。组装后，门124可进一步设在百叶板222的前面。在一些实施例中，门124的下边缘126设在百叶板222的底部边缘或最底部侧向孔224的下面。这样，在关闭位置时，门124可盖住或隐藏百叶板222。相比之下，在门124的打开位置时，可以允许接近百叶板222(例如，使得用户站在冰箱100前面时可以看见百叶板222和侧向孔224)。
回到图3至图6，在示范性实施例中，将室壁230设在机械室210内。如图所示，室壁230通常沿横向T延伸(例如，相对于百叶板222在后方)。室壁230可设在进风口212和出风口214之间(例如，相对于侧向L)。室壁230可帮助封住或界定单独的进风通道(例如，具有横向进风部216或侧向进风部218)和空气输出通道220。在使用过程中，空气输出通道220在机械室210内部进风通道216或218的下游。在一些这种实施例中，室壁230从机械室210的上端232延伸至下端234。这样，可防止通过进风口212进入机械室210的空气立即与从(例如，箱体110的前端120上的)出风口214排出的空气混合。在其它实施例中，室壁230安装或固定在箱体110的底盘或底板236上(例如，所述底盘或底板用于界定机械室210的最底部)。
在某些实施例中，室壁230从前端120延伸到机械室210从后端122向前的一部分，以界定横向进风部216。此外，在室壁230和箱体110的后端122之间的横向间隙可界定侧向进风部218(例如，作为进风通道的延续或一部分)。在一些这种实施例中，在左侧116和室壁230之间沿着侧向L，同时在前端120和空气处理器242之间沿着横向T，界定输出通道220。在右侧118和室壁230之间沿着侧向L，同时在前端120和侧向进风部218之间沿着横向T，界定至少一部分进风通道(例如，横向进风部216)。相对于流体流动，侧向进风部218可设在横向进风部216和输出通道220之间。这样，在使用过程中，空气可在到达输出通道220之前(例如)可从横向进风部216流向侧向进风部218。
如上所述，可将密封制冷系统的一个或多个部分装设在机械室210内。在一些实施例中，将用于压缩或促使制冷剂通过密封系统的压缩机238在机械室210内(例如，在输出通道220中)安装在箱体110上。在另外的或替代性实施例中，将冷凝器240(例如，与压缩机238流体相通)装设在机械室210中。例如，可将冷凝器240靠近箱体110的后端122设置(例如，在进风通道的横向进风部216或侧向进风部218处，如图所示)。在一些这种实施例中，冷凝器240设在压缩机238的后方。
在一些实施例中，空气处理器242(例如，风扇或鼓风机)装设在机械室210内，以促使或推动气流从中流过(例如，从进风口212到出风口214)。例如，可使空气处理器242对准压缩机238或冷凝器240，以将空气吸入密封系统的各个部分，并促进或推动密封系统与周围环境之间的热交换。在一些实施例中，空气处理器242设在压缩机238的上游。在另外的或替代性实施例中，空气处理器242设在冷凝器240的下游。可选地，可将空气处理器242沿着横向T设在压缩机238和冷凝器240之间。在另外的或替代性实施例中，空气处理器242设在输出通道220和进风通道216、218之间(例如，在冷凝器240和压缩机238之间)。因此，输出通道220可以是正压通道，而进风通道216、218是负压通道。在可选实施例中，贯穿箱体110的后端122设置一个或多个二级孔244，与空气处理器242流体相通，以提供补充或二级空气与来自进风通道216、218的空气混合(例如，在横向进风部分218或输出通道220内部)。
如图所示，靠近百叶板222设置多个侧向间隔开的叶片246、248。在一些实施例中， 叶片246、248固定或安装在百叶板222上。例如，可用一种或多种胶粘剂、焊接点或机械紧固件将叶片246、248直接固定在百叶板222上。这样，选择性地从箱体110拆卸或安装百叶板222可有利于拆卸或安装机械室内的叶片246、248。
通常，叶片246、248从百叶板222向后延伸(例如，在出风口214处)。这样，组装后，叶片246、248定位成与百叶板222的面向前的表面相对，并且有利地隐藏起来，使用户无法看到或接触到。每个叶片246、248沿着侧向L彼此间隔开。这样，可在相邻叶片246、248之间界定独立的空气通路。组装后，叶片246、248可定位在输出通道220的至少一部分内(例如，前端120的近端)。在可选实施例中，叶片246、248可设在压缩机238或空气处理器242的前面(例如，沿着或相对于横向T)。
在某些实施例中，(例如，第一组叶片246的)一个或多个叶片设置成远离右侧118或进风口212。例如，一个或多个叶片246A、246B可不平行于横向T。至少一个叶片246、248可远离(例如)第二端228界定一个流动角度θ1(例如，相对于横向)。可选地，多个叶片246可远离第二端228界定一个流动角度θ1。在一些这种实施例中，多个分开的叶片246界定多个分开的流动角度θ1。例如，当离散叶片246之间的侧向距离相对于第二端228或进风口212增加时，流动角度θ1可相对于横向T总体上依次增大。这样，由第二端228近端的第一叶片246A界定的流动角度θ1可以小于由第二端228远端的第二叶片246B界定的流动角度θ1(即，与第一叶片246A相比为远端)。有利的是，可以基本上防止来自出风口214的空气与进入机械室210的空气混合(例如，通过进风口212)。
在另外的或替代性实施例中，(例如，第二组叶片248的)一个或多个叶片设置成远离左侧116。例如，一个或多个叶片248可不平行于横向T。至少一个叶片248可远离(例如)第一端226界定一个流动角度θ2(例如，相对于横向)。可选地，多个叶片248可远离第一端226界定一个流动角度θ2。在一些这种实施例中，多个分开的叶片248界定多个分开的流动角度θ2。例如，当离散叶片248之间的侧向距离相对于第一端226增加时，流动角度θ2可相对于横向T总体上依次增大。
这样，由第一端226近端的第一叶片248A界定的流动角度θ2可以小于由第一端226远端的第二叶片248B界定的流动角度θ2(即，与第一叶片248A相比为远端)。
在可选实施例中，提供了第一组叶片246(例如，指向左侧116)和第二组叶片248(例如，指向右侧118)。在一些这种实施例中，第一组叶片246还指向第二组叶片248，反之亦然。这样，可将从第一组叶片246引导的空气引到箱体110前面与来自第二组叶片248的空气融合。此外，第一组叶片246可设在右侧118的近端，而第二组叶片248可设在左侧116的近端。
现在简要地参考图7，图中提供了冰箱100的另一个示范性实施例。如图所示，冰箱100包括分立的主箱体110和副箱体310。通常，应理解，主箱体110可包括机械室210，所述机械室210包括上述特征中的一个或多个。副箱体310可包括一个或多个类似特征。例如，副箱体310可在左侧(例如，第一侧面)316和右侧(例如，第二侧面)318之间沿着侧向L延伸，以界定冷藏室324和机械室410(例如，在冷藏室324的下面)。副箱体310的机械室410可包括单独的进风口412和出风口414。如上面在机械室210的上下文中所述，进风口412可设在右侧318的近端，而出风口414可设在左侧320的近端。在可选实施例中，副箱体310的门324可以可转动地附接在与主箱体110的门124相对的一侧(例如，左侧316)。
如图所示，副箱体310的右侧318可抵靠在主箱体110的左侧116上。副箱体310的机械室410的进风口412可设在主箱体110的机械室210的出风口214的近端。在一些这种实施例中，机械室210内的多个叶片(例如，图3中第二组248)指向右侧118。有利的是，从机械室210输出的空气因此可被引导远离机械室410的进风口412。
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。
