本发明的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。
附图说明
图1是根据本发明实施例的烤箱的示意图。
附图标记：
烤箱100，腔体1，风道2。
具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1描述根据本发明实施例的烤箱100。
如图1所示，根据本发明实施例的烤箱100，包括：腔体1、加热组件、风道2、散热 风机和温度检测元件，其中，腔体1内形成有烹饪腔，食物可放入烹饪腔内烹饪；加热组件用于对腔体1的内部空间加热，以实现对食物的烹饪和烤制。
风道2设在腔体1上，散热风机与风道2适配，散热风机用于驱动气流沿风道2流通，从而实现对腔体1散热。温度检测元件设在风道2上，温度检测元件用于检测风道2内的温度，温度检测元件与散热风机信号传输，用于在风道2内的温度高于预定温度时启动散热风机。换言之，在风道2内的温度低于预定温度时，散热风机不工作，由此，可以提高加热组件的加热效率，快速提升腔体1内的温度，减少不必要的热量损失，而且，由于散热风机在风道2内的温度低于预定温度时不启动，从而可以节约能耗，提高烤箱100的能效。
根据本发明实施例的烤箱100，不仅可以提高加热组件对腔体1的加热效率，快速提升腔体1内的温度，还可以减少散热风机的运行时间，节约能耗，提高烤箱100的能效。
在本发明的一些实施例中，腔体1上可以形成有连通腔体1内外空间的通气孔，且通气孔可以与风道2连通。当加热组件加热时，腔体1内的空气受热膨胀，腔体1内的气体可以通过通气孔排出，从而可以起到散热的效果。
有利地，通气孔可以形成于腔体1的顶壁上，且风道2的至少一部分可以设在腔体1顶部，由于空气受热气流会向上流动，将通气孔和风道2的至少一部分设在腔体1的顶部，可以优化烤箱100的结构，使结构更加合理。
优选地，散热风机可以设在风道2上邻近通气孔的一端。
在本发明的一些实施例中，预定温度可以在45°到60°的范围内。当风道2内的温度达到或超过45°到60°的范围内时，可以启动散热风机对腔体1进行散热，由此，可以使于东温度的设定更为合理，实现提高加热组件加热效率的同时，降低散热风机的能耗。
当然，本发明不限于此，预定温度也小于45°或大于60°，例如，预定温度可以为40°、50°、55°、65°、70°等。
在本发明的一些实施例中，温度检测元件可以与散热风机串联，温度检测元件可以为温控器，此温控器在温度高于预定温度时闭合，由于温度检测元件与散热风机串联，当温控器闭合时散热风机通电启动，对腔体1散热；且温控器在温度低于预定温度时断开，由于温度检测元件与散热风机串联，当温控器断开时散热风机不通电不工作。
在本发明的另一些实施例中，温度检测元件可以与散热风机并联，温度检测元件可以为温控器，此温控器在温度高于预定温度时断开，由于温度检测元件与散热风机并联，当温控器断开时散热风机通电启动，对腔体1散热；且温控器在温度低于预定温度时闭合，由于温度检测元件与散热风机并联，当温控器闭合时散热风机不通电不工作。
也就是说，本申请通过温度检测元件本身的结构控制散热风机的启动和关闭，而不是通 过电子式(例如PCB或单片机程序)的方式对散热风机进行控制，由此，不仅结构更加简单，还可以降低成本，且由于不涉及程序内容而单一依赖温度检测元件本身的性能，运行时不易出现故障，可靠性较高。
在本发明的一些实施例中，温度检测元件还可以具有温度下阈值，温度下阈值低于预定温度值，温度检测元件与散热风机串联，且温度检测元件为温控器；该温控器在温度高于预定温度时闭合，同时，该温控器在温度低于温度下阈值时断开。此时由于温度检测元件与散热风机串联，当温度高于预定温度温控器闭合时，散热风机可以通电启动并对对腔体1散热；而当温度低于温度下阈值温控器断开时，散热风机也为断开断电状态，不工作。
在另一些实施例中，温度检测元件与散热风机并联，且温度检测元件为温控器；该温控器在温度高于预定温度时断开，且该温控器在温度低于温度下阈值时闭合。这样，由于温度检测元件与散热风机串联，当温度高于预定温度温控器断开时，散热风机可以通电启动并对对腔体1散热；而当温度低于温度下阈值温控器闭合时，散热风机被短路为断开断电状态，不工作。
也就是说，本申请可以通过两个不同的温度值(预定温度和温度下阈值)分别控制温控器的闭合和断开，换言之，利用一个温度范围的上限和下限分别控制控制温控器的启停，由此，可以使得对温度检测元件启停的控制更加合理。
具体地，预定温度值可以为55℃，且温度下阈值可以为45℃。例如，当风道2内的温度高于55℃时，散热风机可以启动工作，为腔体1散热；当风道2内的温度低于45摄氏度时，散热风机停止工作。
有利地，温度检测元件可以包括一个或间隔布置的多个，优选地，温度检测元件为膨胀式温控器。膨胀式温控器具有延时的效果，因此在膨胀式温控器控制所述散热风机停止工作时，风道2内的温度已经降低到了低于预定温度值一定范围，因此，可以不设置温度下阈值也可以实现避免散热风机长时间保持启动的目的。
根据本发明第二方面实施例的烤箱100的控制方法，所述烤箱100包括腔体1、加热组件、风道2和散热风机，腔体1内形成有烹饪腔，加热组件用于对腔体1的内部空间加热，以实现对食物的烹饪和烤制。风道2设在腔体1上，散热风机与风道2适配，散热风机用于驱动气流沿风道2流通，从而实现对腔体1散热。
所述控制方法包括：检测风道2内的温度，直到风道2内的温度不低于预定温度值时启动散热风机。也就是说，当温度未达到预定温度值时，不启动散热风机，仅加热组件对腔体1进行加热，这样可以提高加热组件的加热效率，快速提升腔体1内的温度，减少不必要的热量损失，而且，由于散热风机在风道2内的温度低于预定温度时不启动，从而可以 节约能耗，提高烤箱100的能效。
根据本发明实施例的烤箱100的控制方法，不仅可以提高加热组件对腔体1的加热效率，快速提升腔体1内的温度，还可以减少散热组件的运行时间，节约能耗，提高烤箱100的能效。
在一些实施例中，在加热组件启动后开始检测风道2内的温度；和/或以预定周期检测风道2内的温度。
有利地，控制方法还可以包括：在风道2内的温度不高于温度下阈值时断开散热风机，其中，温度下阈值低于预定温度值。
优选地，预定温度值为55℃，温度下阈值为45℃。
下面将参考图1描述根据本发明一个具体实施例的烤箱100。
参照图1，烤箱100包括：腔体1、加热组件、风道2、散热风机和温度检测元件。
具体地，如图1所示，腔体1内形成有烹饪腔；腔体1上形成有连通腔体1内外空间的通气孔，通气孔形成于腔体1的顶壁上，风道2设在腔体1上；且风道2的至少一部分设在腔体1顶部。散热风机设在风道2上邻近通气孔的一端，散热风机与风道2适配用于驱动气流沿风道2流通；加热组件用于对腔体1的内部空间加热。
温度检测元件设在风道2上用于检测风道2内的温度，温度检测元件包括一个或间隔布置的多个，温度检测元件为膨胀式温控器。
温度检测元件还具有温度下阈值，温度下阈值低于预定温度值，温度检测元件与散热风机串联，温度检测元件为在温度高于预定温度时闭合且在温度低于温度下阈值时断开的温控器；或温度检测元件与散热风机并联，温度检测元件为在温度高于预定温度时断开且在温度低于温度下阈值时闭合的温控器。其中，预定温度值为55℃，且温度下阈值为45℃。
下面描述上述烤箱100的控制方法，所述控制方法包括：在加热组件启动后开始检测风道2内的温度；直到风道2内的温度不低于预定温度值时启动散热风机。在风道2内的温度不高于温度下阈值时断开散热风机，其中，温度下阈值低于预定温度值。优选地，预定温度值为55℃，温度下阈值为45℃。
根据本发明实施例的烤箱100，由于散热风机在达到预设温度值后才启动，因此，加热组件对腔体1的加热速度块，加热效率高，而且可以减少散热风机的运行时间，降低能耗，节能环保。
