背景技术
烤箱灶具设备通常包括机壳和设置在其中的用于接收用于烹饪的食物的隔热烹饪腔室。加热元件定位在烹饪腔室内，以向位于其中的食物提供热量。加热元件可以包括定位在烹饪腔室的底部的烘烤加热元件、定位在烹饪腔室的顶部的炙烤加热元件和/或对流加热组件。烤箱灶具设备还经常包括具有多个燃烧器组件(比如电阻线圈、燃气燃烧器或感应式加热组件)的炉灶。
在这种烤箱设备的操作期间，加热元件和燃烧器组件的操作可以在设备内和设备周围产生大量的热能。烤箱设备因此需要用于管理由各种加热元件和燃烧器产生的热能的特征。例如，传统的烤箱设备限定在机壳和隔热烹饪腔室之间的空气气室，其容纳设备控制器、加热元件接头以及需要冷却的其它电子器件。另外，烤箱设备的侧部面板和其它表面通常需要显著的冷却以满足规定标准。
因此，传统的烤箱设备包括用于管理加热的空气的流和调控部件温度的冷却系统。例如，风扇可以定位在烤箱设备内，以持续地移除空气气室内的加热的空气，并用较冷的环境空气来补充空气，从而冷却烤箱的电子器件和容纳它们的机壳。可能需要大型风扇来增加空气流速率，但其通常成本高且占据机壳内的许多有限空间。使用多个较小的风扇可以解决成本和空间问题，但是由于与冷却空气从多个出口 排放相关联的膨胀损失，这可能导致糟糕的系统效率。
因此，提供用于改进的热管理的特征的烤箱设备将是有用的。更特别地，用于烤箱设备的在机壳内高效地推动冷却空气的紧凑型风扇组件将是特别有益的。

具体实施方式
现在将详细参考本发明的实施例，其一个或更多示例在附图中示出。提供每个示例是为了解释本发明，而不是限制本发明。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或精神的情况下，可以在本发明中进行各种修改和变化。例如，作为一个实施例的一部分示出或描述的特征可以与另一个实施例一起使用，以产生又一个实施例。因此，本发明旨在覆盖落入所附权利要求及其等同物的范围内的这些修改和变化。
图1和图2描绘了可以根据本公开的方面构造的示例性烤箱设备100。具体地，图1提供了根据本主题的示例性实施例的烤箱设备100 的透视图。图2提供了透视图，其中烤箱设备100的顶部面板被移除以露出内部的电子部件。如示出的，烤箱设备100通常限定了竖直方向V、侧向方向L、以及横向方向T，它们中的每个都相互垂直，使得总体上限定了正交坐标系统。
烤箱设备100包括隔热机壳102。烤箱设备100的机壳102沿着竖直方向V在顶部104和底部106之间延伸，沿着侧向方向L在第一侧部108(当从前部观察时，左侧部)和第二侧部110(当从前部观察时，右侧部)之间延伸，并且沿着横向方向T在前部112和后部114之间延伸。
机壳102限定了被构造为用于接收待烹饪的一种或更多种食物的上部烹饪腔室120和下部烹饪腔室122。因此，烤箱设备100通常被称为双烤箱灶具设备。然而，如本领域技术人员将理解的，烤箱设备100仅以示例的方式提供，并且本主题可以用于任何合适的烹饪设备。因此，本主题可以与其它烤箱设备一起使用，比如壁式烤箱、电烤箱、燃气烤箱、微波烤箱等。另外，图1中示出的示例性实施例不旨将本主题限制成任何特定的烹饪腔室构造或布置。
烤箱设备100包括可旋转地附接至机壳102的上部门124和下部门126，以便允许分别选择性地进入上部烹饪腔室120和下部烹饪腔室122。手柄128安装到上部门和下部门124和126上，以帮助用户打开和关闭门124和126，以便进入烹饪腔室120和122。作为示例，用户可以拉动安装到上部门124上的手柄128上，以打开或关闭上部门124，并进入上部烹饪腔室120。门124、126可以包括窗130，其例如由多个平行玻璃窗格构成，以提供对隔热烹饪腔室120、122的内容物的观察并使之隔热。
现在具体参考图4，加热元件132(比如电阻加热元件、燃气燃 烧器、微波加热元件、卤素加热元件或它们的合适组合)定位在上部烹饪腔室120和下部烹饪腔室122内，用于加热上部烹饪腔室120和下部烹饪腔室122。一个或更多个烘烤机架(未示出)可以定位在隔热烹饪腔室120、122中，以便接收食物或容纳食物的器具。烘烤支架可以可滑动地接收在凸起的肋或滑动轨道上，使得当门124、126打开时，烘烤支架可以方便地移入和移出隔热烹饪腔室120、122。
如示出的，隔热烹饪腔室120、122中的每一个由多个腔室壁134限定。例如，隔热烹饪腔室120、122中的每个包括沿着竖直方向V间隔开的顶部壁和底部壁。左侧壁和右侧壁在顶部壁和底部壁之间延伸，并且沿着侧向方向L间隔开。后部壁可以另外地在顶部壁和底部壁之间以及在左侧壁和右侧壁之间延伸，并且沿着横向方向T与门124、126间隔开。以这种方式，当门124、126处于关闭位置时，限定了烹饪空腔。
根据示出的实施例，隔热烹饪腔室120、122的腔室壁134被描绘为简单的围绕烹饪空腔的隔热材料的块体。然而，本领域技术人员将理解，隔热材料可以由一种或更多种合适的材料构成，并且可以采用任何合适的形状。例如，隔热材料可以被封装在一个或更多个刚性结构构件中，比如板状金属面板，其提供结构刚性和用于附接例如加热元件、温度探针、支架滑动组件和其它机械或电子部件的安装表面。
以类似的方式，机壳102包括多个面板136，所述面板包围隔热烹饪腔室120、122。例如，机壳102包括底部面板、前部面板、后部面板、左面板、右面板等。当处于关闭位置时，门124、126可以平齐地抵靠前部面板就位。根据示出的实施例，机壳102的面板136是单层板状金属面板，但是本领域技术人员将理解，可以使用任何合适的刚性面板，同时保持在本主题的范围内。例如，根据示例性实施 例，面板136可以由合适的刚性和耐热的塑料构成。此外，每个面板136可以包括由相同或不同材料制成的多个层，并且可以形成为任何合适的形状。
参考图1，烤箱设备100还包括炉灶140。炉灶140定位在机壳102的顶部104处或邻近其顶部处。因此，炉灶140定位在上部烹饪腔室120上方并且包括定位在机壳102的顶部104附近的顶部面板142。作为示例，顶部面板142可以由玻璃、陶瓷、搪瓷钢及它们的组合构成。多个燃烧器组件144安装在顶部面板142内或其顶部上。更具体而言，根据示出的实施例，炉灶140是感应式炉灶，并且每个燃烧器组件144是感应式燃烧器。如图1所示，燃烧器组件144可以被构造成各种尺寸，以便提供例如用于接收具有各种尺寸和构造的烹饪器具(即，罐、平底锅等)并提供用于这种烹饪器具的不同热量输入。
烤箱设备100进一步配备有控制器150，以调控烤箱设备100的操作。例如，控制器150可以调控包括加热元件132、燃烧器组件144等的烤箱设备100的操作。控制器150可以(经由例如合适的有线或无线连接)与加热元件144和烤箱设备100的其它合适的部件通信，如本文所讨论的。通常，控制器150可以可操作为配置烤箱设备100(及其各种部件)，以用于烹饪。这种配置可以基于选择的操作循环的多个烹饪要素、传感器反馈等。
作为示例，控制器150可以包括一个或更多个存储器装置和一个或更多个微处理器，比如可操作为执行与操作循环相关的微控制代码或编程指令的通用或专用用途的微处理器。存储器可以表示随机存取存储器(比如DRAM)，或只读存储器(诸如ROM或FLASH)。在一个实施例中，处理器执行存储在存储器中的编程指令。存储器可以 是与处理器分开的部件，或者可以被包括搭载在处理器内。
控制器150可以定位在遍及烤箱设备100的各个位置。在示出的实施例中，控制器150可以位于烤箱设备100的用户接口面板或控制面板152内，如图1和2所示。在这样的实施例中，输入/输出(“I/O”)信号可以沿着可以穿过机壳102而布线的线束在烤箱设备100的控制系统和各种操作部件之间传输。通常，控制器150与控制面板152和控制件154通信，用户可以通过控制件选择各种操作特征和模式，并监测烤箱设备100的过程。在一个实施例中，控制面板152可以表示通用I/O(“GPIO”)装置或功能块。在一个实施例中，控制面板152可以包括输入部件或控制件154，比如一个或更多个各种电气、机械或机电输入装置(包括旋转拨盘、按钮和触摸板)。控制面板152可以包括显示器部件，比如被设计成向用户提供操作反馈的数字或模拟显示器装置156。
控制面板152可以经由一个或更多个信号线或共享通信总线与控制器150通信。控制器150还可以与一个或更多个传感器通信，例如，温度传感器，其用于测量隔热烹饪腔室120、122内的温度并将这些测量结果提供给控制器150。温度传感器可以是热电偶、热敏电阻、电阻温度检测器或适于测量隔热腔室120、122内的温度的任何其它装置。以这种方式，控制器150可以响应于控制面板152的用户操纵和来自温度传感器的温度反馈而选择性地控制加热元件144。控制器150还可以接收来自放置在隔热腔室120、122内的温度传感器的温度测量结果，并且例如通过显示器156向用户提供温度指示。
尽管本文在包括感应式炉灶的双烤箱设备的背景下描述了本主题的方面，但是应该理解，烤箱设备100仅作为示例提供。在这点上，本主题不限于烤箱设备100的任何特定样式、型号或构造。例如，具 有不同构造、不同外观和/或不同特征的其它烤箱或灶具设备也可与本主题一起使用，例如单烤箱、电炉灶烤箱、燃气炉灶烤箱等。此外，本主题的方面可以用在需要高效冷却设备部件的任何其它消费者或商业设备中。
现在总体参考图2至图4，隔热烹饪腔室120、122定位在机壳102内，使得隔热烹饪腔室120、122的壁134和机壳102的面板136限定了在隔热烹饪腔室120、122与机壳102之间的各种空气流动通路。这些通路(在本文中通常可以被称为空气气室160)通常可以被构造用于容纳设备部件和接收贯穿烤箱设备100的冷却空气流。
例如，各种烤箱设备100的部件(比如，加热元件和其它炉灶部件)可以被定位在空气气室160中，该空气气室在图2至4中被示出为被限定在上部烹饪腔室122的顶部面板142与顶部壁134之间。空气可以通过由机壳102限定的各种孔和/或通道流动到空气气室160中。以这种方式，较冷的环境空气可以流动到机壳102中并且通过空气气室160，从而从烤箱设备100中的电子部件和其它表面上抽出热量，该热量可以从烤箱设备100中排出。
现在参考图2至7，将根据本主题的示例性实施例描述可以与烤箱设备100一起使用的风扇组件200。通常，风扇组件200被放置成与空气气室160流体连通，并被构造为用于推动冷却空气流动通过空气气室160，例如，以冷却电子部件和隔热烹饪腔室120、122。尽管风扇组件200的具体构造在本文中被描述成用于与烤箱设备100一起使用，但是应该理解的是，本主题的方面可以被用在其它设备中，例如，作为设备冷却系统的部分。此外，在保持处于本主题的范围内的同时，可以对风扇组件200进行修改和变化。
如示出的，风扇组件200包括安装在机壳102的顶部后部中心中 的单个风扇支架206上的第一风扇202和第二风扇204。由于第一风扇202和第二风扇204之间的相似性，相似的附图标记可以用于指代第一风扇202和第二风扇204中的每一个上的相同或相似特征。类似地，尽管第一风扇202和第二风扇204实际上推动单独的空气流，但是来自风扇组件200的空气流在图中总体上使用附图标记208标识。通常，风扇组件200定向成使得冷却空气流208沿着基本上沿着横向方向T延伸的中心流动轴线210被推动。应该理解，如本文所使用的，近似的术语，比如“近似”，“基本”，或“大约”指的是在百分之十界限的误差内。
如图2和3中最佳示出的，风扇组件200被定位并定向成用于冷却烤箱设备100的各种部件。例如，烤箱设备100可以包括电子器件壳体220，其限定了用于容纳各种电子部件224的电子器件隔室222。例如，电子器件壳体220被示出为定位在炉灶140与上部烹饪腔室120的顶部腔室壁134之间的空气气室160内的刚性塑料托盘。电子器件壳体220通常可以被构造用于接收电子部件224并且限定用于引导冷却空气流208的流动路径。
定位在电子器件壳体220内的电子部件224可以包括例如滤波板226，其用于在使用电力为感应式燃烧器组件144供能之前对电力进行滤波。另外，电子器件壳体220可以包括一个或更多个热交换器228，以助于热量消散。在这点上，例如，交换器228可以包括具有热交换鳍片的挤出铝制散热器，所述热交换鳍片基本上沿着横向方向T延伸，使得冷却空气流208穿过热交换器228以移除热量并降低电子器件隔室222内的温度。具体地，如示出的，冷却空气的流动208总体上沿着中心流动轴线210和在中心流动轴线210的相对的侧向侧部上间隔开的两个散热器热交换器228流动。以这种方式，冷却空气 流208的大部分可以在热交换器228之间穿过，例如，以冷却滤波板226和控制面板152。
另外，冷却空气流208可以穿过控制面板152或者在其下方穿过，以冷却容纳在其中的电子部件。具体地，冷却空气流可以沿着横向方向T穿过电子器件壳体220到达控制面板152，在控制面板处，冷却空气流可以在通过限定在机壳102的前部面板136中的排气口230被排放之前冷却容纳在控制面板152内的电子器件。尽管冷却空气流208被示出为沿着横向方向被向前推动并且从限定在机壳102的前部112处的排气口230推出，但是应当理解的是，在保持在本主题的范围内的同时，可以使用其它气流方向、入口和出口。例如，气流可以反向，可以从另一位置被抽吸，并且可以在机壳102上的任何合适位置排出。
根据示出的实施例，第一风扇202和第二风扇204是离心或径流式风扇。在这点上，第一风扇202包括限定第一进口242、第一蜗壳244和第一出口246的第一壳体240。在操作期间，鼓状的叶轮248旋转以通过第一进口242将冷却空气流208抽吸到第一壳体240中。然后，在通过第一出口246排放冷却空气流208之前，叶轮248沿着径向方向R对着第一蜗壳244推动空气流208向外。类似地，第二风扇204包括限定第二进口252、第二蜗壳254和第二出口256的第二壳体250。第二风扇204以与第一风扇202类似的方式操作。尽管示出为离心或径向风扇，但应当理解的是，根据替代实施例，风扇组件200可以包括任何合适数量、类型和构造的风扇。
根据示出的实施例，第一风扇202和第二风扇204例如通过使用机械紧固件、胶水、搭扣配合机构等安装到板状金属风扇支架206。然而，应该理解的是，根据替代实施例，第一风扇202和第二风扇 204可以被制造成单个组件，其包括在单独限定的风扇壳体/蜗壳内的两个风扇。具体地，例如，第一壳体240和第二壳体250可以模制为单个零件，并限定两个风扇壳体，所述两个风扇壳体限定单独的出口并被构造成用于接收单独的风扇叶轮。以这样的方式，风扇组件200的制造和组装可以被简化。
如图5至7中最佳地示出，第一风扇202和第二风扇204定位成邻近彼此并定向成使得冷却空气流208基本上沿着相同方向(例如，沿着横向方向T或沿着中心流动轴线210)被引导离开出口246、256。在这点上，例如，风扇组件200可以关于在第一风扇202和第二风扇204之间延伸的中心流动轴线210对称。另外，第一风扇202和第二风扇204可以是彼此的镜像，使得第一进口242和第二进口252都被限定在相应的壳体240、250的底部壁258上，而第一蜗壳244和第二蜗壳254限定了邻近彼此的出口246、256。
更具体地说，如图3和4中最佳示出的，烤箱设备100可以在烹饪腔室120、122的后部壁134和机壳102的后部面板136之间限定后部气室260。多个入口可以限定在机壳102的后部面板136和/或侧部面板内，以允许新鲜空气流动到机壳102中。风扇202、204可以抽吸冷却空气流208向上通过后部气室260进入到第一进口242和第二进口252中。然后，冷却空气流208可以沿着中心流动轴线210被向前推动，例如，以冷却电子器件隔室222内的电子部件224。
值得注意的是，离心风扇(比如，第一风扇202和第二风扇204)通常在它们相应的出口246、256处限定高速度侧部264和低速度侧部266。具体地，由于沿着径向方向R并且对着蜗壳244、254推动空气流208向外的叶轮248的构造，冷却空气流208在出口246、256和蜗壳244、246的径向外边缘处具有更高的速度。相反，出口246、 256的径向内侧部通常限定了低速度侧部266。换句话说，当叶轮248的叶片旋转时，在距旋转的轴线最远的边缘处的空气比在最接近旋转的轴线的边缘处的空气移动得更快，使得出口246、256处的速度分布是非线性的。如示出的，第一风扇202和第二风扇204的高速度侧部264邻近彼此定位，而低速度侧部266彼此分开。图7中示出了风扇定向和冷却空气流208的速度的示意性表示。
由于在出口246、256处的非线性速度分布，更多空气在出口246、256的高速度侧部264上离开。当冷却空气流208离开出口246、256时，它可能经历快速膨胀，这导致显著的膨胀损失。这些膨胀损失与速度成正比，因此在高速度侧部264上看到了更多的损失。然而，如本文所述的定位并定向第一风扇202和第二风扇204可以通过允许空气流208在出口246、256的下游相互作用而使高速度侧部264上的损失最小化。应当理解的是，术语"上游"和"下游"指代相对于流体通路中的流体流动的相对方向。例如，"上游"指代的是流体流动来的方向，"下游"指代的是流体流动去的方向。
在这点上，例如，风扇组件200可以限定紧接地在第一风扇202和第二风扇204的下游以允许离开出口246、256的空气流208之间的相互作用的空隙区域270。如本文所用，"空隙区域"用于指代空气气室160内的开放空间，其不容纳用于基本干扰或隔离空气流208的设备部件或特征。在这点上，例如，空隙区域270是出口246、256和热交换器228之间的空间，在该空间内没有挡板、流动导引特征或其它部件。值得注意的是，允许离开第一风扇202和第二风扇204的空气流208在空隙区域270内相互作用显著降低了在出口246、256处的膨胀损失，从而改进了风扇组件200的效率。
根据本主题的示例性实施例，第一壳体240和第二壳体250可以 在出口246、256附近彼此直接接触。在这种实施例中，可以减小效率损失，并且可以使用更小的风扇，同时实现与较大的风扇相同的气流，从而最小化风扇组件200的占用空间和相关的操作成本。
根据示出的实施例，第一壳体240和第二壳体250可以由第一出口246和第二出口256附近的气隙280分开。在这点上，例如，气隙280可以是(例如，沿着侧向方向L)第一壳体240和第二壳体250之间的足以允许夹带空气流282(见图7)穿过气隙280并与空气流208混合的任何间距。例如，根据示出的实施例，气隙280小于约0.25英寸，尽管其它合适的尺寸也是可以的，并且在本主题的范围内。
值得注意的是，将第一风扇202和第二风扇204定位成使得气隙280被限定在它们之间，这产生了文丘里效应，该文丘里效应抽吸夹带空气282以增加由风扇202、204推动的空气的总量，同时还使由于在出口246、256处的膨胀的效率损失最小化。例如，总空气流208和夹带空气282可以大于第一风扇202和第二风扇204在分开操作时的流动速率的总和的15％。因此，风扇组件200可以具有更小的占用空间，可以更加高效地操作，并且可以根据需要维持调控设备温度。
本书面描述使用示例来公开本发明，包括最佳模式，并且允许本领域任何技术人员实践本发明，包括制造和使用任何装置或系统以及执行任何结合的方法。本发明的专利范围由权利要求限定，并且可以包括本领域技术人员想到的其它示例。如果这样的其它示例包括不与权利要求的字面语言不同的结构元件或者如果它们包括与权利要求的字面语言无实质差异的等同结构元件，则这些其它示例意图在权利要求的范围内。
