  • Heating a multi-cavity oven apparatus to properly cook/bake food requires the ability to supply heat to each oven cavity that is substantially independent of another cavity or other cavity. Traditionally, this is achieved by supplying a roasting burner to each oven cavity, supplying a broiler burner to at least one of the cavities, and optionally supplying an additional heat source with a fan for convection . This requires separate burners or electrical components for each of these heat sources. Such a configuration may be costly, reduce the available cooking volume in the oven device, increase complexity, and may reduce the reliability of the oven device. For example, a multi-chamber oven device using a gas system may face baking performance limitations.

Description

具有自然对流和强制对流的多腔体烤箱设备 技术领域
本主题总体上涉及多腔体烤箱设备，比如双烤箱灶具设备。
背景技术
各种烤箱设备可以包括多于一个的烹饪室。例如，这样的多腔体烤箱设备可以包括具有上部烹饪室和下部烹饪室的双烤箱灶具设备。双烤箱灶具设备的用户可以方便地利用上部烹饪室和下部烹饪室中的任一个或两个来烹饪食品。在某些双烤箱灶具设备中，上部烹饪室小于下部烹饪室。因此，用户可以利用上部烹饪室来烹饪较小的食品，并且利用下部烹饪室来烹饪较大的食品。
加热多腔体烤箱设备以恰当地烹饪/烘烤食物需要能够向每个基本上独立于另一腔体或其它腔体的烤箱腔体供应热量。传统上，这通过以下来实现：将烘烤燃烧器供应到每个烤箱腔体、将炙烤燃烧器供应到腔体中的至少一个以及可选地供应具有用于对流的风扇的额外的热源。这需要用于这些热源中的每一个的独立燃烧器或电气元件。这样的构造可能是成本高的，减少了烤箱设备内的可用烹饪体积，增加了复杂性，并且可能减小烤箱设备的可靠性。例如，利用气体系统的多腔体烤箱设备可能面临烘烤性能限制。在给定的时间，在任一腔体中，只有一个气体燃烧器可以被点燃，因为同时的燃烧器操作可能导致燃烧不良。在这样的系统中，烘烤与炙烤之间的过渡可能需要显著的时间，因为需要关闭一个燃烧器并随后点燃另一燃烧器。作为另一个示例，典型的多腔体烤箱设备仅在一个腔体中提供对流加热，或者必须增加另一个对流系统的额外成本以在其它腔体中提供对流。
因此，具有用于提供对烤箱设备的灵活操作(例如，通过选择性地将热量引导到多个腔体中的一个或更多个)的特征的多腔体烤箱设备将是有用的。此外，具有提供灵活操作同时最小化烤箱设备内的加热系统的占地面积的特征的 多腔体烤箱设备将是有用的。
发明内容
本发明的方面和优点将部分地在以下描述中阐述，或者可以从描述中显而易见，或者可以通过本发明的实践来学习。
在一个示例性实施例中，提供了一种烤箱设备。烤箱设备限定竖直方向、侧向方向和横向方向。竖直方向、侧向方向和横向方向是相互垂直的。烤箱设备包括沿着侧向方向在第一侧部分和第二侧部分之间延伸的机壳。机壳还沿着竖直方向在顶部部分和底部部分之间延伸。机壳限定了邻近机壳的顶部部分定位的上部烹饪室和邻近机壳的下部部分定位的下部烹饪室。烤箱设备还包括单一热源，其选择性地通过强制对流与上部烹饪室和下部烹饪室中的一个或两个直接热连通或者通过自然对流与烤箱设备周围的外界环境直接热连通。
在另一个示例性实施例中，提供了一种烤箱设备。烤箱设备包括具有上部烹饪室和下部烹饪室的机壳，所述上部烹饪室限定在机壳中邻近机壳的顶部部分，所述下部烹饪室限定在机壳中在上部烹饪室下方并邻近机壳的下部部分。烤箱设备还包括单一热源，其通过自然对流与烤箱设备周围的外界环境直接热连通。烤箱设备进一步包括风扇，其可操作为通过强制对流提供从单一加热部到上部烹饪室和下部烹饪室中的一个或两个的直接热连通。

具体实施方式
现在将详细参考本发明的实施例，其一个或更多个示例在附图中示出。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型。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型。
图1提供了根据本主题的示例性实施例的多腔体烤箱灶具设备100的透视 图。在图1示出的示例中，烤箱灶具设备是包括两个腔体的双烤箱设备。理解的是，这仅仅是举例，本公开的额外的实施例可以包括三个或更多个腔体。在示出的示例中，多腔体烤箱设备100包括用于每个腔体的单独的门，例如，相应地对应于上部腔体和下部腔体的上部门121和下部门125。在额外的实施例中，可以设置单个门以用于同时进入烤箱设备100内的全部多个腔体。其它组合和变型也是可行的，例如具有两个门的三腔体烤箱设备等。
如图1中可以看到的，烤箱设备100限定了竖直方向V、侧向方向L和横向方向T。竖直方向、侧向方向和横向方向相互垂直，并形成正交方向系统。
烤箱设备100包括隔热机壳110。机壳110比如沿着竖直方向V在顶部部分111和底部部分112之间延伸。因此，机壳110的顶部部分和底部部分111、112比如沿着竖直方向V彼此间隔开。机壳110比如还沿着侧向方向L在第一侧部分113与第二侧部分114之间延伸。因此，机壳110的第一侧部分与第二侧部分113、114比如沿着侧向方向L彼此间隔开。例如，从站在烤箱设备100的前部(例如，用于伸手进到腔体中的一个中和/或用于接近控制件)的用户的视角来看，第一侧部分113可以是右侧部分，并且第二侧部分114可以是左侧部分。机壳110进一步例如沿着横向方向T在前部部分115和后部部分116之间延伸。因此，机壳110的前部部分和后部部分115、116例如沿着横向方向T彼此间隔开。
在所示示例中，烤箱设备100包括定位在机壳110的顶部部分111处或邻近顶部部分定位的炉灶130。炉灶130包括被构造成用于加热定位在其上的炊具的各种加热元件132，比如气体燃烧器、电阻元件、感应元件等。在额外的实施例中，烤箱设备100可以是内置烤箱或壁式烤箱，例如，在其上没有炉灶130。
如图1所示，机壳110还限定上部烹饪室120和下部烹饪室124。因此，烤箱设备100通常被称为双烤箱灶具设备。如本领域技术人员将理解的，双烤箱灶具设备100仅作为示例提供，并且本主题可以在各种组合中用在任何合适的多腔体烤箱设备中，例如，三腔体烤箱设备(或更多)，双腔体壁式烤箱设备等。
上部烹饪室120定位在机壳110的顶部部分111处或邻近顶部部分定位。相反地，下部烹饪室124定位在机壳110的底部部分112处或邻近底部部分定位。因此，上部烹饪室和下部烹饪室120、124沿着竖直方向V彼此间隔开。上部烹饪室和下部烹饪室120、124可以具有相对于彼此的任何合适尺寸。例如，如图1所示，上部烹饪室120可以小于下部烹饪室124。
上部烹饪室和下部烹饪室120、124被构造成用于接收一个或更多个待烹饪食品。上部门121和下部门125可移动地附接或联接到机壳110，例如，通过铰接件可旋转地联接，以便相应地允许选择性地接近上部烹饪室120和下部烹饪室124。手柄123、127安装到上部门和下部门121、125，以帮助用户打开和关闭门121、125，以接近烹饪室120、124。作为示例，用户可以拉动安装到上部门121上的手柄123，以打开或关闭上部门121，并接近上部烹饪室120。在门121、125关闭时，玻璃窗面板122、126提供了对上部烹饪室和下部烹饪室120、124的内容物的观察，并且还帮助使上部烹饪室和下部烹饪室120、124隔热。
烤箱设备100的控制面板140定位在机壳110的顶部部分111和后部部分116处。控制面板140包括用户输入142。控制面板140提供了对烤箱设备100的操作的用户操纵的选择。例如，用户可以触摸控制面板140以触发用户输入142中的一个。响应于用户输入142的用户操纵，烤箱设备100的各个部件(比如各个加热元件)可以操作。
如在图2至5中可以看到的，上部烹饪室120和下部烹饪室124可以彼此热隔离。例如，隔热分隔件150可以在上部烹饪室120和下部烹饪室124之间延伸。将理解的是，隔热分隔件150可以沿着竖直方向V定位在上部烹饪室120和下部烹饪室124之间。此外，隔热分隔件150可以主要沿着侧向方向L和横向方向T延伸，例如，隔热分隔件150的主尺寸可以沿着侧向方向和横向方向L和T设置，而隔热分隔件150的竖直尺寸可以比侧向尺寸或横向尺寸小得多。例如，隔热分隔件150可以沿着侧向方向L从机壳110的左侧114延伸到机壳110的右侧113，并且可以沿着横向方向T从机壳110的前部部分115延伸到机 壳110的后部部分116。
烤箱设备100包括被构造成向烹饪室120和124提供热量(例如，经由被加热空气的对流热量)的一个或更多个加热元件160。加热元件160可以是任何合适的加热元件，比如电阻加热元件、气体燃烧器、微波元件等。在一些实施例中，可以设置一种以上类型的加热元件，例如电阻加热元件和气体燃烧器可以组合地设置。一个或更多个加热元件160可以选择性地与多腔体烤箱设备100中的腔体中的一个或更多个热连通和/或与烤箱设备100周围的外界环境热连通。例如，在示出的示例性实施例中，在一个或更多个风扇190、192和/或194被启用时，一个或更多个加热元件160可以通过强制对流选择性地与上部烹饪室120和下部烹饪室124中的一个或两个热连通。在设置多于一个加热元件160的实施例中，加热元件160可以共同限定单一热源，例如，加热元件160可以定位在一起以使加热元件160在机壳110的整个体积内的占用面积最小化。这样，单一热源在本文中被用来指代来自烤箱设备100内的单一位置的热量，并且该热量可以由在单一位置中定位在一起的一个或更多个加热元件160提供。
如图2-9中示出的，加热元件160可以定位在烹饪室120和124的外部。例如，加热元件160可以通过第二隔热分隔件152与烹饪室120和124分开，而加热元件160仅通过对流与烹饪室120和124热连通，如将在下文进一步描述的。第二隔热分隔件152可以沿着竖直方向V定位在下部烹饪室124下方，并且沿着竖直方向V定位在加热元件160上方。与上文所述的第一隔热分隔件150类似，第二隔热分隔件152可以主要沿着侧向方向L和横向方向T延伸。例如，第二隔热分隔件152可以沿着侧向方向L从机壳110的左侧114延伸到机壳110的右侧113，并且可以沿着横向方向T从机壳110的前部部分115延伸到机壳110的后部部分116。
如上所述，加热元件160可以与上部烹饪室120和下部烹饪室124中的一个或两个或者与烤箱设备100周围的外界环境选择性地热连通。例如，加热元件160可以选择性地与烹饪室120和124中的一个或两个或者外界环境直接热 连通。如将在下文更加详细地描述的，加热元件160可以选择性地与烹饪室120和124中的一个或两个直接流体连通以将被加热的空气1000从加热元件160直接提供至烹饪室120和124中的一个或两个。这种选择性可以通过操作一个或更多个风扇190、192、194以引导被加热的空气1000至对应的一个或更多个腔体120/124来提供。这样的热连通可以由在加热元件160与烹饪室120和124之间延伸的多个管道来提供。例如，烤箱设备100可以包括：第一管道170，其直接从加热元件160延伸至与烤箱设备周围的外界环境流体连通的通气口172；第二管道172，其直接从加热元件160延伸至上部烹饪室120中的炙烤出口175；第三管道176，其直接从入口177延伸至上部烹饪室120中的烘烤出口178；以及，第四管道180，其直接从入口182延伸至下部烹饪室124中的烘烤出口184。烤箱设备100还可以包括：第一风扇190，其定位并构造成将空气从第一管道170推动到第二管道174中；第二风扇192，其定位且构造成将空气从第一管道170推动到第三管道176中；以及第三风扇194，其定位且构造成将空气从第一管道170推动到第四管道180中。如将在下文更加详细地描述的，风扇190、192和194的选择性启用或停用可以提供从加热元件160到烹饪室120和124中的一个或两个的选择性热连通。
图2示意性地示出了这样的情况，其中，加热元件160通过第一管道170和通气口172与外界环境直接热连通。如在示出实例实施例中，在加热元件160定位在通气口172下方的情况下，来自加热元件160的被加热的空气1000将通过自然对流从加热元件160流动(例如，上升)到第一管道170中并穿过第一管道流动到通气口172。例如，在烹饪操作完成之后来自加热元件160的残余热量可以通过自然对流穿过第一管道170行进到通气口172，并且从通气口行进到烤箱设备100的外部的外界环境。这样的构造可以有利地减少或避免烹饪室120和/或124中的物品(例如食品)过热(例如过度烹饪)。因此，加热元件160和通气口172可以被构造成用于通过自然对流在上部烹饪室120中的从加热元件160至通气口172的直接热连通。例如，当第一风扇190、第二风扇192和第三 风扇194被停用时，被加热的空气1000可以上升到通气口172。
现在具体转向图3，上部烹饪室120的炙烤操作被示意性地示出。如图所示，加热元件160可以经由第二管道174与上部烹饪室120直接热连通。特别地，加热元件160可以经由第二管道174与上部烹饪室120的炙烤出口175热连通。如本领域普通技术人员将理解的，炙烤出口175可以定位在上部烹饪室120的顶部壁154处或附近。例如，在一些实施例中，上部烹饪室120的炙烤出口175可以靠近顶部壁154，如例如图3中所示。如图所示，当第一风扇190启用时，穿过第一管道170上升的被加热的空气1000可以从自然通路转向，并且通过第一风扇190被迫使或推动进入第二管道174，比如经由第二管道174的入口173(图2)，如图所示。因此，第一风扇190可以提供从加热元件160到上部烹饪室120的炙烤出口175的强制对流。如图所示，第二管道174的入口173可以定位在第一管道170中和/或与第一管道170流体连通。第二管道174可以沿着竖直方向V定位在通气口172下方。例如，第二管道174的入口173可以竖直地定位在通气口172下方。因此，在至少一些实施例中，第二管道174的入口173可以定位在加热元件160和通气口172之间的第一管道170中的中间点处。在第二管道174的入口173在通气口172下方的情况下，被加热的空气1000的一些或全部可以在被加热的空气1000到达通气口172之前通过第一风扇190从自然通路转移，并且被加热的空气1000然后可以穿过第二管道174被引导到炙烤出口175，例如被加热的空气1000中的一些或全部可以通过第一风扇190从第一管道170处转移并且被推动到第二管道174中并穿过第二管道。因此，加热元件160以及上部烹饪室120可以被构造成用于通过强制对流从加热元件160到上部烹饪室120中的炙烤出口175的热连通。
现在转向图4，示意性地描绘出了上部烹饪室120中的烘烤操作，例如，其中被加热的空气1000被提供至上部烹饪室120的烘烤出口178。如图所示，当第二风扇192启用时，穿过第一管道170上升的被加热的空气1000中的一些或全部可以从自然通路被转移，并且通过第二风扇192被迫使或推动进入第三管 道176，比如经由第三管道176的入口177，如图所示。因此，第二风扇192可以提供从加热元件160到上部烹饪室120的烘烤出口178的强制对流。如图所示，第三管道176的入口177可以定位在第一管道170中和/或与第一管道170流体连通。第三管道176可以沿着竖直方向V定位在通气口172下方。例如，第三管道176的入口177可以竖直地定位在通气口172下方。同样作为示例，第三管道176的入口177可以竖直地定位在加热元件160和第二管道174的入口173上方。因此，在至少一些实施例中，第三管道176的入口177可以定位在加热元件160和上部烹饪室120中的通气口172之间的第一管道170中的中间点处。在第三管道176的入口177在通气口172下方的情况下，被加热的空气1000中的一些或全部可以在被加热的空气1000到达通气口172之前通过第二风扇192从自然通路转移，并且被加热的空气1000然后可以穿过第三管道176被引导到烘烤出口178，例如被加热的空气1000中的一些或全部可以通过第二风扇192从第一管道170处被转移并且被推动到第三管道176中并穿过第三管道。因此，加热元件160和上部烹饪室120可以被构造为用于使用第一风扇190和第二风扇192中的任一个或两个通过强制对流从加热元件160到上部烹饪室120的热连通。
现在转向图5，示意性地描绘出了下部烹饪室124中的烘烤操作，例如，其中被加热的空气1000被提供至下部烹饪室124的烘烤出口184。如图所示，当第三风扇194启用时，穿过第一管道170上升的被加热的空气1000中的一些或全部可以从自然通路转移，并且通过第三风扇194被迫使或被推动进入第四管道180，比如经由第四管道180的入口182，如图所示。因此，第三风扇194可以提供从加热元件160到下部烹饪室124的烘烤出口184的强制对流。如图所示，第四管道180的入口182可以定位在第一管道170中和/或与第一管道170流体连通并且沿着竖直方向V在通气口172下方。例如，第四管道180的入口182可以竖直地定位在通气口172下方并且在加热元件160和第二管道174的入口173上方。因此，在至少一些实施例中，第四管道180的入口182可以定位 在加热元件160和通气口172之间的第一管道170中的中间点处。同样作为示例，第四管道180的入口182可以竖直地定位在第三管道176的入口177下方。在第四管道180的入口182在第三管道176的入口177和通气口172下方时，被加热的空气1000中的一些或全部在被加热的空气1000到达通气口172和/或第三管道176的入口177之前通过第三风扇194从自然通路转移。被加热的空气1000然后可以穿过第四管道180被引导至烘烤出口184，例如可以通过第三风扇194被推动到第四管道180中并穿过第四管道。
如上所述，加热元件160可以与上部烹饪室120和下部烹饪室124中的两个选择性地热连通。例如，如图6所示，当第二风扇192被启用而第三风扇194也被启用时，被加热的空气1000的第一部分可以通过第二风扇192经由入口177被推动到第三管道176中，并且被加热的空气1000的第二部分可以通过第三风扇194经由入口182被推动到第四管道180中。被加热的空气1000的第一部分然后可以从第三管道176的入口177穿过第三管道176被推动至上部烹饪室120中的烘烤出口178，并且被加热的空气1000的第二部分然后可以穿过第四管道180被推动至下部烹饪室124中的烘烤出口184。因此，当第二风扇192和第三风扇194二者同时启用时，加热元件160可以与上部烹饪室120和下部烹饪室124二者热连通，随后，可以在上部烹饪室120和下部烹饪室124二者中提供烘烤操作。
作为另一个示例，图7示出了加热元件160，其与上部烹饪室120和下部烹饪室124二者热连通以用于上部烹饪室120中的炙烤操作和下部烹饪室124中的烘烤操作。如图7所示，当第一风扇190启用而第三风扇194也启用时，被加热的空气1000的第一部分可以通过第一风扇190经由入口173被推动到第二管道174中，并且被加热的空气1000的第二部分可以通过第三风扇194经由入口182被推动到第四管道180中。被加热的空气1000的第一部分然后可以从第二管道174的入口173穿过第二管道174被推动至上部烹饪室120中的炙烤出口175，并且被加热的空气1000的第二部分然后可以穿过第四管道180被推动 至下部烹饪室124中的烘烤出口184。因此，当第一风扇190和第三风扇194二者同时启用时，加热元件160可以与上部烹饪室120和下部烹饪室124二者热连通，随后，可以在上部烹饪室120中提供炙烤操作并且在下部烹饪室124中提供烘烤操作。
图8示意性地示出了烤箱设备100在第一风扇190和第二风扇192二者同时启用而第三风扇194未启用时的操作。在该操作中，烘烤和炙烤二者都可以被提供在上部烹饪室120中。例如，被加热的空气1000的第一部分可以通过第一风扇190经由入口173被推动到第二管道174中，并且被加热的空气1000的第二部分可以通过第二风扇192经由入口177被推动到第三管道176中。被加热的空气1000的第一部分然后可以从第二管道174的入口173穿过第二管道174被推动至上部烹饪室120中的炙烤出口175，并且被加热的空气1000的第二部分然后可以穿过第三管道176被推动至上部烹饪室120中的烘烤出口178。
图9示意性地示出了烤箱设备100在第一风扇190、第二风扇192和第三风扇194全部同时启用时的操作。在该操作中，烘烤和炙烤二者都可以提供在上部烹饪室120中以及在下部烹饪室124中的烘烤操作。在单一热源包括多个共同定位的加热元件160的情况下，多于一个的加热元件160可以在该操作期间被启用，其中多于一个的风扇，比如全部三个风扇190、192和194被启用。例如，如图9所示，被加热的空气1000的第一部分可以经由入口173通过第一风扇190被推动到第二管道174中，被加热的空气1000的第二部分可以经由入口177通过第二风扇192被推动到第三管道176中，并且被加热的空气1000的第三部分可以经由入口182通过第三风扇194被推动到第四管道180中。被加热的空气1000的第一部分然后可以从第二管道174的入口173处穿过第二管道174被推动到上部烹饪室120中的炙烤出口175，被加热的空气1000的第二部分然后可以穿过第三管道176被推动到上部烹饪室120中的烘烤出口178，并且被加热的空气1000的第三部分然后可以穿过第四管道180被推动到下部烹饪室124中的烘烤出口184。
