请参考图1-15，本实施例提供一种烹饪设备。
请参考图1-10，该烹饪设备包括主体部100、导热体200、散热风扇300和导流结构400。
主体部100具有烹饪腔体110，导热体200设置于主体部100的侧部，导热体200用于传导热源的热量，导热体200具有散热流道210，散热流道210具有进风口211和出风口212。散热风扇300设置于导热体200的进风口211，散热风扇300用于产生气流，散热风扇300产生的气流从进风口211进入散热流道210，并从出风口212排出散热流道210。导流结构400具有导流流道410，导流流道410具有第一部分411和第二部分412，第一部分411与出风口212配合，第二部分412向远离散热风扇300的方向延伸。第一部分411具有导流入口4111，第二部分412具有导流出口4121，出风口212排出的气流从导流入口4111进入导流流道410，并从导流出口4121排出导流流道410。
当散热风扇300工作时，气流先经过散热流道210，再从导流入口4111进入导流流道410，接着在导流流道410的引导下向远离散热风扇300的方向流动，最后从导流出口4121排出。由于导流流道410将气流导向了远离散热风扇300的位置，从而降低了导流流道410排出的气流 被散热风扇300再次吸入可能性，进而有利于规避散热效率降低的风险。
需要说明的是，“第二部分412向远离散热风扇300的方向延伸”可以作更具体和可量化的理解，例如，可以从第二部分412与第一部分411之间的夹角的角度取值范围来理解。
具体地，请参考图1-10，在一种实施例中，主体部100具有相对设置的第一侧和第二侧，第一侧具有取放开口120，取放开口120将烹饪腔体110与外界连通。散热流道210从第一侧所在的平面向第二侧所在的平面延伸，散热流道210靠近第一侧的一端具有出风口212，散热流道210的中部具有进风口211。第一部分411的延伸方向与散热流道210的延伸方向相同，第二部分412的延伸方向与第一部分411的延伸方向之间的夹角成钝角，以使第二部分412向远离散热风扇300的方向延伸。
由于第一部分411的延伸方向与散热流道210的延伸方向相同，使得散热流道210排出的气流能够不受阻碍地进入第一部分411的导流入口4111，这有利于减小气流进入导流流道410内的流阻，从而有利于提升散热效果。而由于第二部分412的延伸方向与第一部分411的延伸方向之间的夹角成钝角，使得第二部分412能够向远离散热风扇300的方向延伸，从而有利于将气流导向远离散热风扇300的位置，再从导流出口4121排出。
在实际的应用场景中，导流结构400的形状可以是直线形、弧线形、直线形与弧线形的结合或各种不规则的形状，下面以导流结构400为直线形和导流结构400为直线和弧线形的结合两种情况为例进一步说明“第二部分412的延伸方向与第一部分411的延伸方向之间的夹角成钝角”的含义。
当导流结构400为直线形和弧线形的结合时，请参考图10，在一种实施例中，第一部分411的中心线a1为从主体部100的第一侧向主体部100的第二侧延伸的直线，第二部分412的中心线a2为弧线，第二部分412的弧线a2上任一位置的切线b与第一部分411的中心线a1的夹角均为钝角，以实现第二部分412的延伸方向与第一部分411的延伸方向之间的夹角成钝角。
当导流结构400为直线形时，请参考图15，在一种实施例中，第一部分411的中心线a1为从主体部100的第一侧向主体部100的第二侧延伸的直线，第二部分412的中心线a2为直线，第二部分412的中心线a2与第一部分411的中心线a1的夹角为钝角，以实现第二部分412的延伸方向与第一部分411的延伸方向之间的夹角成钝角。
导流结构400除了能够将气流导向远离散热风扇300的位置外，还可以具有阻拦气流向散热风扇300所在方向流动的功能，二者结合可以进一步降低气流被散热风扇300再次吸入的可能性。
具体地，请参考图6-10，在一种实施例中，第二部分412靠近散热风扇300的一侧具有凸出于第一部分411的阻拦部4122，阻拦部4122用于阻拦导流出口4121排出的气流汇入散热风扇300产生的气流。通过阻拦部4122阻拦气流向散热风扇300所在方向流动，从而有利于进一步降低气流被散热风扇300再次吸入的可能性。
在实际的产品设计中，通常要避免散热气流向操作产品的使用者直吹，以防止直吹气流干扰使用者的操作。也即，散热气流最终的排出方向不应当垂直地朝向烹饪设备供使用者操作的一侧，这一侧通常是烹饪设备的取放开口120所在的一侧。
具体地，请参考图1-3和6，在一种实施例中，主体部100具有相对设置的第一侧和第二侧，第一侧具有取放开口120，取放开口120将烹饪腔体110与外界连通。导流出口4121的朝向不垂直于第一侧所在的平面。
由于导流出口4121的朝向不与第一侧所在的平面垂直，使得从导流出口4121排出的气流不会向操作烹饪设备的使用者直吹，从而有利于防止直吹气流干扰使用者的操作。具体地，导流出口4121的朝向可以与第一侧所在的平面成小于90°的夹角，例如，30°、50°或70°，导流出口4121的朝向也可以与第一侧所在的平面成大于90°的夹角，例如，120°、140°或160°。
优选地，当气流的流向作为一种矢量在朝向使用者的一侧上分量为0时，气流对使用者的干扰最小。具体地，请参考图1，在一种实施例中，导流出口4121的朝向与散热通道的延伸方向垂直。使得从导流出口4121排出的气流既不会向使用者直吹，也不会向使用者斜吹，将气流对使用者的干扰降到最低。
请参考图7-10，在一种实施例中，导流结构400的出风口212具有连续起伏的锯齿结构420。设置在出风口212的锯齿结构420有利于降低气流排出出风口212时产生的噪音，从而降低气流噪音对使用者的干扰。
请参考图11-14，在一种实施例中，导流结构400的出风口212具有平整的板状结构430。
一方面，板状结构430可以用于导流结构400的固定，例如，通过贯穿板状结构430的螺丝固定导流结构400。另一方面，在生产过程中，板状结构430相比锯齿结构420更易于开模，因此有利于降低导流结构400的生产成本，且板状结构430的结构强度高于锯齿结构420。
请参考图7和11，在一种实施例中，导流结构400包括分隔板440，分隔板440设置于导流流道410内，用于将导流流道410分隔为多个流道。
通过分隔板440将导流流道410分隔为多个流道，一方面，有利于增强导流结构400对气流的引导作用，另一方面，有利于避免当导流流道410过宽时，气流在导流流道410内形成涡流的可能性。
请参考图7和11，在一种实施例中，导流结构400包括多个相互平行的分隔板440，且分隔板440与散热流道210的延伸方向平行。当分隔板440与散热流道210的延伸方向平行时，有利于降低散热流道210的气流进入导流流道410内的流阻，从而有利于提升散热效果。
需要说明的是，分隔板440的数量和排布方式可以根据实际情况灵活选择，例如，请参考图7，在一种实施例中，分隔板440的数量为多个，且多个分隔板440沿垂直于导流通道的方向等间距地设置。请参考图11，在一种实施例中，分隔板440的数量也可以是两个，两个分隔板440位于导流结构400的中部。
请参考图3-5，在一种实施例中，导热体200包括接触板220和多个导热翅片230，接触板220用于与热源接触，导热翅片230连接于接触板220，相邻的导热翅片230之间的间隙形成散热流道210。
通过接触板220提升导热体200与热源的接触面积，从而有利于提升导热体200的导热效果，通过相邻的导热翅片230之间的间隙形成散热流道210，以增大导热体200与空气的接触面积，从而有利于提升导热体200的散热效果。
具体地，请参考图3-5，散热风扇300可以设置在导热翅片230的中部，以在散热流道210的中部形成进风口211，在散热流道210的端部形成出风口212。本实施例中散热风扇300的数量为两个，在其他实施例中，根据导热体200和散热风扇300具体尺寸的不同，散热风扇300的数量也可以是一个、三个或其他合适的数量。
请参考图3-6，在一种实施例中，烹饪设备还包括制冷装置500，制冷装置500设置于主体部100的侧部，制冷装置500包括换热腔体510和半导体制冷元件520。换热腔体510与烹饪腔体110可选择性地连通和封闭，半导体制冷元件520的冷端位于换热腔体510。热源为半导体制冷元件520的热端，导热体200与半导体制冷元件520的热端接触。
当需要冷藏食品时，通过半导体制冷元件520的冷端对换热腔体510的环境进行制冷，并将换热腔体510与烹饪腔体110连通，换热腔体510可以通过空气对流实现对烹饪腔体110的制冷。当烹饪腔体110需要加热食品时，将换热腔体510与烹饪腔体110封闭，避免烹饪腔体110的高温造成换热腔体510内制冷元件的损坏。
当然，在其他实施例中，热源也可以不是半导体制冷元件520的热端，而是主体部100上的其他发热元件，例如，主体部100上的电控模块等。
另一方面，本实施例还提供一种制冷装置500，该制冷装置500可以应用于上述的烹饪设备。
请参考图1-10，该制冷装置500包括换热腔体510、半导体制冷元件520、导热体200、散热风扇300和导流结构400。
换热腔体510用于与烹饪设备的烹饪腔体110可选择性地连通和封闭，半导体制冷元件520具有冷端和热端，半导体制冷元件520设置于换热腔体510的侧部，且冷端位于换热腔体510内。导热体200与热端接触，导热体200具有散热流道210，散热流道210具有进风口211和出风口212。散热风扇300设置于导热体200的进风口211，散热风扇300用于产生气流，散热风扇300产生的气流从进风口211进入散热流道210，并从出风口212排出散热流道210。导流结构400具有导流流道410，导流流道410具有第一部分411和第二部分412，第一部分411与出风口212配合，第二部分412向远离散热风扇300的方向延伸。第一部分411具有导流入口4111，第二部分412具有导流出口4121，出风口212排出的气流从导流入口4111进入导流流道410，并从导流出口4121排出导流流道410。
请参考图1-10，在一种实施例中，换热腔体510具有相对设置的前侧和后侧。
需要说明的是，换热腔体510的前侧指的是换热腔体510用于朝向使用者的一侧。更具体地，请参考图1，当制冷装置500与主体部100并排设置时，换热腔体510的前侧与主体部100的第一侧为同一侧。因此，也可以将一些结构的位置或方向参考对象从主体部100的第一侧和第二侧替换为换热腔体510的前侧和后侧。
例如，可以理解的是，在一些实施例中，“散热流道210从主体部100的第一侧所在的平面向主体部100的第二侧所在的平面延伸”也可以表述为“散热流道210从换热腔体510的前侧所在的平面向换热腔体510的后侧所在的平面延伸”。
上述实施例的导流结构400以“将气流导向远离散热风扇300的位置”为避免气流被风扇再次吸入的主要思路。在其他实施例中，导流结构400也可以以“阻拦气流向散热风扇300所在方向的流动”为主要思路。
例如，请参考图1-10，在一种实施例中，烹饪设备包括主体部100、导热体200、散热风扇300和导流结构400。
主体部100具有烹饪腔体110，导热体200设置于主体部100的侧部，导热体200用于传导热源的热量，导热体200具有散热流道210，散热流道210具有进风口211和出风口212。散热风扇300设置于导热体200的进风口211，散热风扇300用于产生气流，散热风扇300产生 的气流从进风口211进入散热流道210，并从出风口212排出散热流道210。导流结构400具有导流流道410，导流流道410具有导流入口4111和导流出口4121。出风口212排出的气流从导流入口4111进入导流流道410，并从导流出口4121排出导流流道410。导流结构400靠近散热风扇300的一侧具有阻拦部4122，阻拦部4122用于阻拦导流出口4121排出的气流汇入散热风扇300产生的气流。
当散热风扇300工作时，气流先经过散热流道210，再从导流入口4111进入导流流道410，接着在导流流道410的引导下从导流出口4121排出，由于导流结构400靠近散热风扇300的一侧具有阻拦部4122，阻拦部4122可以对向散热风扇300流动的气流起阻拦作用，从而降低了导流流道410排出的气流被散热风扇300再次吸入可能性，进而有利于规避散热效率降低的风险。
同理，本实施还提供一种制冷装置500，该制冷装置500可以应用于上述的烹饪设备。
请参考图1-10，该制冷装置500包括换热腔体510、半导体制冷元件520、导热体200、散热风扇300和导流结构400。
