下面结合附图1至附图4具体描述根据本发明实施例的烤箱100。
根据本发明实施例的烤箱100包括箱体10、箱门(未示出)和照明灯20，箱体10的前面敞开，箱门可打开地封盖箱体10的前面，照明灯20设在箱体10内的前面，且照明灯20构造成至少一部分光线朝向箱体10内的后面投射，照明灯20的投射光线的中心线与水平面呈预定角度的夹角。
换言之，烤箱100主要由箱体10、箱门和照明灯20组成，箱体10的前侧敞开形成五面封闭一面敞开的结构，箱体10的敞开侧形成食物取放口，食物取放口一侧设有箱门，箱门可活动地连接在箱体10上，并相对于箱体10可旋转，由此实现打开或封闭箱体10的食物取放口，箱体10内腔设有照明灯20，照明灯20设置在箱体10内腔的顶部且靠近箱门的位置，照明灯20背向箱门向箱体10内腔投射光线，且照明灯20的投射光线的中心线与水平面之间形成一定的夹角，该夹角可以在安装照明灯20时设定，需要说明的是，照明灯20的投射光线的中心线，是指照明灯20的光线在预定区域内向外发散，其中，光线发散区域的中心线即为投射光线的中心线。
由此，根据本发明实施例的烤箱100，通过在箱门的内侧设置朝向箱体10后面投射光线的照明灯20，利用照明灯20为箱体10的内腔提供照明，为用户向箱体10内取放食物以及观察食物的烘烤情况提供方便，照明灯20的投射光线的中心线与水平面形成预定的角度，最大程度地提高了照明灯20的照明效果，减少了照明灯20的使用数量，不仅降低了烤箱100的生产成本，还优化了烤箱100的结构设计，而且照明灯20的结构简单，连接可靠，优化了用户的操作体验。
可选地，照明灯20设在箱体10内前面的顶部，且照明灯20的投射光线的中心线射向箱体10内。
具体而言，照明灯20安装在箱体10靠近箱门的一侧，照明灯20可以安装 在箱体10内腔顶部的内壁面上，照明灯20光线的投射方向朝向箱体10内腔，即照明灯20光线的投射方向背对箱门，且照明光线倾斜向下照射，照明灯20的投射光线所在的直线与水平面倾斜布置，使得照明灯20的光线不会直射到用户的眼睛。
将照明灯20设在箱体10的顶部(如图1和图3所示的顶壁的内侧)，降低了照明的对食物的影响，增加了食物放置空间，不仅防止取放食物过程中、人手触碰到照明灯20造成照明灯20的损坏，延长了照明灯20的使用寿命，还能够保护食物不受照明灯20的污染，而且，照明灯20朝向箱体10内腔的后部投射光线，增加了箱体10内的照明条件，为用户放置食物提供了方便，再者，便于用户观察食物的烧烤情况，有利于提高食物的烹饪质量。
参照附图1，在本实施例中，照明灯20设在箱体10内前面顶部的左侧，且照明灯20的投射光线的中心线射向箱体10底部的右侧，照明灯20设在箱体10内前面顶部的右侧，且照明灯20的投射光线的中心线射向箱体10底部的左侧。
具体而言，照明灯20可以设置在箱体10前面顶部的左侧(如图1所示的前侧的左上方)，照明灯20投射光线的中心线朝向箱体10后面的底部右侧(如图1所示的后侧右下方)，也就是说，照明灯20从箱体10前面的左上角向箱体10后面的右下角投射光线。当然，照明灯20也可以设置在箱体10前面顶部的右侧(如图1所示的前侧的右上方)，照明灯20投射光线的中心线朝向箱体10后面的底部左侧(如图1所示的后侧左下方)，即照明灯20从箱体10前面的右上角向箱体10后面的左下角投射光线。
由此，将照明灯20设置在箱体10的位于顶壁的顶角处，使照明灯20可以从箱体10的左上角向右下角投射光线，或从箱体10的右上角向左下角投射光线，均能够最大程度的照亮箱体10内腔的空间，保证箱体10内的食物处在照明光线内，为用户观察食物并了解食物的烹饪情况提供方便，而且进一步消除了用户投放食物过程中对照明灯20的影响。
可选地，照明灯20的投射光线的中心线与水平面之间的夹角为43°。也就是说，照明灯20的光线投射方向所在的直线与水平面之间的夹角为43°，照明灯20从箱体10内腔的左上角向右下角或从右上角向左下角投射光线，投射光线与箱体10的顶面或底面之间的夹角为43°，能够最大程度地优化照明灯20的照明效果，减少了照明灯20的使用数量，简化了烤箱100的结构设计，降低了烤箱100的生产成本。
可选地，箱体10内形成为长方体形状的腔室11，照明灯20的投射光线的中心线沿箱体10内的腔室11的一个对角线延伸。
具体地，箱体10内限定出腔室11，腔室11形成为长方体结构，箱体10的上下端面和侧面形成长方体的四个表面，其中，照明灯20的投射光线的中心线与腔室11所形成的长方体结构中的一条对角线所在的直线重合，例如，照明灯20设在箱体10的顶壁的左前侧，且照明灯20的投射光线的中心线沿腔室11的对角线延伸。
通过将腔室11设置成长方体结构，最大程度地利用了箱体10的内腔空间，增加了箱体10内食物的容量，优化了腔室11的结构设计，而且长方体结构的箱体10生产工艺比较简单，容易实现，消耗材料较少，降低了烤箱100的生产成本，相对于复杂形状的腔室11而言，长方体结构的腔室11投放食物更为简单方便。
进一步地，箱体10内形成为长方体形状的腔室11，其中，在垂直于前后方向的平面上的投影中照明灯20的投射光线的中心线与箱体10内的左侧面或右侧面的夹角在15°到35°的范围内；和/或在垂直于左右方向的平面上的投影中照明灯20的投射光线的中心线与箱体10内的后侧面的夹角在10°到15°的范围内；和/或在垂直于上下方向的平面上的投影中照明灯20的投射光线的中心线与箱体10内的后侧面的夹角在-5°和5°的范围内。
具体而言，在本发明的一个实施例中，照明灯20的投射光线的中心线与箱体10左侧面或右侧面所在的平面之间的夹角大于15°小于35°，例如，可以 是15°，可以是25°，也可以35°。
在本发明的另一个实施例中，照明灯20的投射光线的中心线与箱体10的后面在箱体左侧面或右侧面所在平面上的投影中，照明灯20的投射光线的中心线与箱体10的后侧面之间的夹角大于10°小于15°，例如，可以是10°，可以是13°，也可以是15°。
在本发明的又一个实施例中，照明灯20的投射光线的中心线与箱体10的后面在水平面(如图1所示的上下端面坐在的平面)上的投影中，照明灯20的投射光线的中心线与箱体10的后侧面之间的夹角大于-5°小于5°。
其中，照明灯20的投射光线的中心线与箱体10侧面之间的角度可以根据上述三个实施例中的一个实施例进行限定，也可以同时满足上述实施例限定情况的两个角度，同样也可以同时满足三个实施例限定的角度，即照明灯20的投射光线的中心线与箱体10左侧面或右侧面所在的平面之间的夹角大于15°小于35°，照明灯20的投射光线的中心线与箱体10的后面在箱体左侧面或右侧面所在平面上的投影中，照明灯20的投射光线的中心线与箱体10的后侧面之间的夹角大于10°小于15°，照明灯20的投射光线的中心线与箱体10的后面在水平面上的投影中，照明灯20的投射光线的中心线与箱体10的后侧面之间的夹角大于-5°小于5°。
通过设定照明灯20的投射光线的中心线与箱体10不同侧面之间的角度，最大程度的提升了照明灯20的照明效果，保证腔室11内的明亮程度，减少了照明的20的使用数量，进而在保证烤箱100正常使用的前提下，降低了生产成本。
优选地，箱体10的内表面上形成有容纳槽21，照明灯20设置于容纳槽21内，且照明灯20不突出容纳槽21。
具体地，如图2所示，箱体10的顶壁的内表面设有向内凹陷的容纳槽21，且该容纳槽21邻近食物取放口设置，例如容纳槽21可以设置在食物取放口的右上方或左上方，容纳槽21相对于箱体10的内壁面内陷设置，照明灯20安装 在容纳槽21内，使照明灯20全部容纳在容纳槽21内，不突出于箱体10的内壁面。
由此，通过在箱体10的内壁面上设置容纳槽21，并将照明灯20安装在容纳槽21内，不仅提高了照明灯20的安装稳定性，还能减轻烤箱100内的加热管在工作过程中对照明灯20的影响，降低照明灯20吸收到的热量，而且还能避免用户取放食物过程中、触碰照明灯20对其造成损坏的问题，延长了照明灯20的使用寿命。
可选地，照明灯20为LED灯并连接烤箱100的中心控制板。也就是说，照明灯20采用LED灯，且与烤箱100的中心控制板相连，中央控制板控制照明灯20的打开与关闭。
由于LED灯具有照明亮度大、使用寿命长、抗干扰能力强和耗能低的优势，因此，采用LED灯能够增加照明灯20的工作性能，减轻了加热管对照明灯20的影响，降低了照明灯20的故障率，且降低了烤箱100的能耗，其中，采用中央控制板控制照明灯20大开关，简化了用户使用烤箱100过程中操作步骤，优化了用户的操作体验。
有利地，照明灯20包括一个或关于箱体10沿竖向的对称面对称的两个。
也就是说，箱体10内照明灯20的数量可以是一个也可以是两个，若箱体10内设置一个照明灯20，照明灯20可以设置在箱体10前面的右上角或左上角，如图3所示，在本实施例中，照明灯20设置在箱体10前面的左上角，使照明灯20朝向箱体10的对角线方向罩设。
若箱体10内设置两个照明灯20，两个照明灯20相对于箱体10竖直方向的对称面对称设置，例如，箱体10前面的左上角和右上角各设置一个照明灯20，两个照明灯20分别朝向各自的对角线方向照射，提升对箱体10内腔的照射效果。由此，将箱体10内的照明灯20对称设置，能够增加箱体10内腔的照明效果，提高用户视线的亮度，从而保证用户准确的观察烤箱100内食物的情况，防止食物烘烤时间过短不熟，或烘烤时间过长无法食用。
此外，烤箱100还包括用于控制照明灯20开闭的开关(未示出)，且箱门为透明箱门或箱门上具有用于查看箱体10内部空间的透明视窗(未示出)。
换言之，烤箱100上还设有开关，开关与照明灯20电连接以用于控制照明灯20的打开与关闭，用户通过开关在需要的时候控制照明灯20的打开或关闭，提高了照明灯20工作的灵活性，操作方便，而且降低了能量消耗，节省了电能。
在本发明的一些具体实施方式中，箱门采用透明材质制作或在箱门上设置透明视窗，透明视窗采用透明材质制作，无需打开箱门，用户直接透过透明箱门或箱门上的透明视窗便可观察到箱体10内食物的烘烤情况，防止反复开关箱门而影响食物的烘烤质量，保证食物烘烤一次性完成。
在本发明的另一些具体实施方式中，箱门为不透明箱门，箱门和箱体10中的至少一个上设有用于检测箱门的开关状态的检测开关(未示出)，且检测开关连接照明灯20并在箱门打开时使照明灯20通电。
具体而言，箱门也可以采用不透明材质制作，且不在箱门上设置透明视窗，在箱门或箱体10上设置检测开关，也可以在箱门和箱体10同时设置检测开关，照明灯20与检测开关电性连接，利用检测开关检测箱门的开关状态，当箱门打开时，检测开关控制照明灯20打开，当箱门关闭时，检测开关关闭照明灯20。
当箱门处于关闭状态，检测开关控制照明灯20关闭，降低能耗；当箱门处于打开状态时，检测开关控制照明灯20打开，实现照明的效果，方便用户使用，无需用户单独控制照明灯20。由此，通过在箱门和箱体10中的一个或两个上设置检测开关，并利用检测开关根据箱门的开关状态控制照明灯20的开关，用户在使用烤箱100过程中无需单独操作控制照明灯20，且照明灯20根据箱门的打开开关状态自行控制开启照明，提高了烤箱100的自动化程度，而且在保证用户照明的前提下节省了电能消耗。
