本申请提出一种电烤机100。
请结合参照图1至图3，在本申请一实施例中，该电烤机100，包括外壳10以及容置于外壳10内的内壳30和加热装置50，内壳30位于所述外壳10和加热装置50之间，内壳30和加热装置50之间围成有隔热腔60。
本申请外壳10为塑料材质，并通过一体注塑方式生产完成。内壳30可为不锈钢材质或者铝合金材质。其中外壳10为长方体的框体形状，其上下两端设置开口，内壳30和加热装置50均设置于外壳10所围成的空间内。内壳30也呈框体结构，其形状和外壳10的形状相匹配，外壳10套设于内壳30外部。内壳30可由多段金属板首尾拼接构成。本申请电烤机100在外壳10和内壳30的底部连接有底壳80，底壳80滑动连接有接油盘90，并在金属外壳10的上端架设有烤架70，在电烤机100工作过程中，加热装置50向烤架70方向辐射出加热光线，对放置于烤架70上的食物进行非接触式加热，食物如肉类在加热过程中，产生的油脂可下落并滴落于接油盘90，当然食物所带的水分也可滴落于接油盘90由接油盘90进行收集。由于接油盘90和底壳80为滑动连接，可于电烤机100的一侧将接油盘90拉出，方便清理接油盘90上的油污。
本申请技术方案通过在电烤机100的加热装置50和内壳30之间形成隔热腔60，在电烤机100加热食物过程中，加热装置50以及烤架70上的热量因为隔热腔60的空气保温层的作用，使得加热装置50产生的热量向电烤机100外部辐射传导的能力被大大削弱，降低了加热装置50的热量损失，提高了电烤机100的食物加热效率，同时降低了外壳10的温度，降低了触摸电烤机100外壳10时被烫伤的风险，使用者在电烤机100附近时也不会感到过于炎热，使得电烤机100的使用效果更佳。
可以理解的，本实施例的隔热腔60可以是密闭腔体，也可以是设有开口的腔体，本实施例的隔热腔60优选为密闭腔体，当隔热腔60为设有开口的腔体时，其可于内壳30的下部分设置有开口，而内壳30和加热装置50的上部分为封闭结构。
为了提高本电烤机100的隔热保温性能，所述加热装置50位于隔热腔60所在高度范围之间。如此可以实现隔热腔60的空间区域包覆加热装置50的外壁。本申请的隔热腔60的空间区域完全包覆加热装置50朝向外壳10一侧的外壁，如此可形成对加热装置50向外壳10方向辐射出的热量进行较完全的隔离效果，使得电烤机100的隔热保温效果更好。
请参照图3，加热装置50包括反射罩51、以及安装于反射罩51的辐射热源53，反射罩51形成有反射腔55，辐射热源53位于反射腔55内，反射罩51的周缘和内壳30抵接，反射罩51背离辐射热源53的一侧外壁和内壳30共同围成隔热腔60。
本申请加热装置50通过辐射热源53进行热量辐射而对食材进行加热，辐射热源53为红外灯管。反射罩51所形成的反射腔55的腔道整体为向上倾斜设置，并且在反射腔55的上部设置有第一让位口（未标示），从而实现将辐射热源53所辐射出的热量导向架设于内壳30上端的烤架70，实现烤架70上食物的非接触式加热。其中反射罩51可以是金属材质（如铝合金）的基体，并于基体面向辐射热源53的一侧表面覆盖反射材料层（如镀锌层）的结构，反射罩51可为一体式板状结构并通过弯折形成，也可以是由多块板材拼接构成。本实施例的辐射热源53也可以替换为卤素灯、线圈式灯丝、陶瓷加热器等结构。
可以理解的，本实施例还可于反射罩51与内壳30的抵接处设置有密封圈，其中密封圈可为耐高温的塑料材质，如此可以在加热装置50与内壳30的连接处形成柔性缓冲，在搬运电烤机100的过程中，具有辐射热源53的加热装置50更不容易因碰撞而损坏，同时也可以提高隔热腔50的密封性，并且也减少反射罩51通过接触式热传递传导至内壳30的热量，从而进一步减少本电烤机100向除了烤架70方向以外方向辐射的热量，电烤机100的热利用率得到提升，加热效果进一步提高。
本实施例利用反射罩51的外壁和内壳30围成隔热腔60，实现对加热装置50向外壳10方向辐射热量的阻隔，结构简单的同时，也提高电烤机100的加热效率。
为了进一步减少电烤机100向外壳10方向辐射热量的损失，提升本电烤机100的加热效率。本实施例内壳30面向反射罩51的表面涂覆有反射层（未标示），该反射层为镀锌层或镀铝层。
通过于内壳30面向反射罩51的表面涂覆反射层，则加热装置50向外壳10方向辐射的热量可通过内壳30反射回去，相当于在隔热腔60的基础上再添加一个反射罩，如此更进一步减少热量的损失，提高电烤机100的加热效率
本实施例加热装置50还包括保护窗57，保护窗57封盖于第一让位口而与反射罩51围成密闭空间。
所述保护窗57优选为玻璃材质。保护窗57的设置一方面可对辐射热源53所发出的光线（如紫外线）进行过滤，降低辐射热源53发出的有害光线对人体的危害，提高了本电烤机100的安全性，另一方面保护窗57与反射罩51围成密闭空间，辐射热源53处于封闭的环境内，在食物加热过程中，下滴至接油盘90的油滴或水分不会溅射至辐射热源53上，如此避免了油滴或水分对辐射热源53的腐蚀，提高了电烤机100的使用寿命。
由上述的内容可知， 所述内壳30为与外壳10相适配的框体结构，内壳30包括两长侧边，加热装置50设有两个，一所述加热装置50安装于一所述长侧边，且每一所述加热装置50在所述长侧边的长度方向上延伸。内壳30以及两加热装置50围成容置腔31，两个加热装置50位于容置腔31内的相对两侧，
本申请的电烤机100通过两个相对设置的加热装置50，一方面使得烧烤架70上的食物实现相对两侧同时加热，食物受热均匀，烧烤后获得的食物成品品质优良，另一方面也提高了食物的加热效率。
请参照图3，所述内壳30或反射罩51的上端形成有第二让位口（未标示），将烤架70架设于第二让位口处，且烤架70部分嵌设于第二让位口内。通过将烤架70部分嵌设于第二让位口内内，一方面可以提升烤架70安装后结构的稳固性，另一方面，将隔热腔60延伸至烤架70的两侧，使得隔热腔60对烤架70所在平面的两侧进行包裹，则烤架70向外壳10方向热传递的能力被削弱，两个加热装置50所辐射出的热量也较多的聚集在烤架70上，则对烤架70上食物的加热效率得到进一步提升。
由于本实施例构成隔热腔60的内壳30和加热装置50的反射罩51的侧壁均为金属材质，即隔热腔60由金属材料围成，并且隔热腔60为上端封闭的腔体。则在电烤机100食物加热过程中，由于加热装置50的加热作用，隔热腔60内的热空气上升，较多热量聚集在隔热腔60的上端，而又因为烤架70架设于第二让位口，靠近隔热腔60的上端，在电烤机100使用过程中，隔热腔60上端的温度可接近烤架70的温度，则烤架70与隔热腔60之间的温差较小，从而减少了烤架70的热量通过隔热腔60的顶部进行热传递而散失，则电烤机100的热利用率更高，食材的加热效果更好。
请结合参照图3和图4，所述内壳30或反射罩51于第二让位口处设置有抵接斜面33（本实施例抵接斜面33形成于内壳30），烤架70形成有导向斜面71，当烤架70部分嵌入第二让位口内时，抵接斜面33和导向斜面71相互平行或抵接设置。
本实施例通过抵接斜面33和导向斜面71的配合，使得烤架70安装于内壳30上端开口时结构更稳固，并且安装过程中对位也较方便，同时，在抵接斜面33和导向斜面71相抵接的情况下，内壳30于抵接斜面33的部分在辐射热源53热辐射光线照射过程中发热，热量通过导向斜面71传递至烤架70的周缘，如此处于烤架70周缘的食物也能得到较高温度加热，烤架70上的食材的加热效果更好，加热效率更高。
当所述抵接斜面33和所述导向斜面71相互平行时，本实施例抵接斜面33和导向斜面71的间距范围为大于0小于等于3毫米。如此烤架70的装配结构更牢固，同时导热能力得到进一步提高。
在上述内容中，本申请实施例通过设置在内壳30和加热装置50之间围成有隔热腔60，来减少加热装置50向外壳10方向辐射损伤的热量，提高热利用率，同时降低外壳10的温度，使得本申请的电烤机100使用安全。而本申请为了进一步提升本电烤机100使用的安全性，在降低外壳10温度的方案上还进行了以下设计。
具体地，请再次结合参照图1至图3，本申请于外壳10和内壳30之间形成有散热通道20，本申请技术方案通过采用在电烤机100的外壳10和内壳30之间形成散热通道20，在电烤机100加热食物过程中，加热装置50向外壳10方向辐射的热量，具体而言，加热装置50将热量传递至内壳30，内壳30面向外壳10一侧表面的热量被散热通道20内的空气对流带走排出，而只有较少的热量能传递至外壳10，使得外壳10在电烤机100工作过程中不会温度过高，一方面可以避免外壳10处于较高温度环境下出现变形老化现象，另一方面可以避免使用者触摸外壳10而被烫伤，则电烤机100的安全性能得到提升。
本实施例散热风道20的上端开设有出风口24，并且出风口24外壳10位于靠近内壳30的一侧，具体而言，所述底壳80盖合连接于外壳10和内壳30的下端，底壳80开设有连通散热通道20的进风口22，外壳10的上端开设有连通散热通道20的出风口24，即出风口24设于外壳10的靠近内壳30的一侧。
在本电烤机100工作过程中，散热风道20内的风流向为至下而上，进入散热风道20内的空气由电烤机100的侧边向上方吹出。采用底部进风的方式，可以避免散热通道200的进风口22将架设烤架70上的食材在烧烤过程中产生的少量油烟进入散热通道20，造成散热通道20的内壁被油污覆盖，而较难清洗。同时，本申请的烧烤机100通过外壳10、内壳30以及底壳80合围成散热风道20，形成可拆卸方案，在电烤机100的后期拆装维护时更方便。
进一步地的，本申请还将内壳30和外壳10之间的间距设为3到30毫米，在电烤机100食物加热过程中，加热装置50产生的热量通过内壳30向外壳10方向辐射时，由于内壳30和外壳10的间距设置，使得内壳30向外壳10的热传递能力被大大削弱，电烤机使用过程中，外壳10不会升温过高，则可以避免外壳10处于较高温度环境下而出现变形老化现象，同时可以避免使用者触摸外壳10而被烫伤，则电烤机100的安全性能得到提升，另外内壳30和外壳10之间3到30毫米的间距设置，也使得电烤机100的整体结构紧凑。
具体而言，本方案内壳30包括相连接的水平段32和折弯段34，外壳10包括相连接的封盖段12和倾斜段14，水平段32和封盖段12相对设置，折弯段34和倾斜段14相对设置，水平段32和封盖段12之间的间距小于折弯段34和倾斜段14之间的间距。
本实施例内壳30的水平段32和折弯段34为内壳30的中间部分，并且水平段32位于上方，内壳30还包括分别与水平段32和折弯段34连接的板体部分，使得内壳30整体为近似长方体开口的罩体形状，即水平段32和折弯段34为罩体的中间部分。其中水平段32和折弯段34共同构成上述的长侧边以对应加热装置50设置。外壳10也由封盖段12和倾斜段14构成近似长方形开口的罩体形状，其中折弯段34和倾斜段14对应电烤机100的机身的侧部具有较大的面积，在电烤机100加热过程中，加热装置50产生向外壳10方向辐射的热量也较多通过折弯段34和倾斜段14进行热传递，本实施例通过将折弯段34和倾斜段14的间距设置得比较大，则折弯段34向倾斜段14传递温度的能力被削弱，则外壳10的温度不会升高过快。
进一步地，所述倾斜段14和竖直面的夹角a的范围为5到30度。本实施例倾斜段14为向电烤机100的内部倾斜，使得电烤机100整体具有梯形的横截面，在电烤机100使用过程中，使用者更不容易触碰到外壳10。
为了实现较佳的散热效果，所述散热通道20靠近进风口22一端的内腔横截面面积大于靠近出风口24一端的内腔横截面面积。由于热空气一般具有向上运动的趋势，本电烤机100食物加热过程中，大量空气由进风口22进入散热通道20，由于在进风口22至出风口24的方向上为缩口设置，使得散热风道20内的空气流速加快，散热效果更好。
进一步地，所述进风口22和/或出风口24处设置有防尘网（未图示）。通过防尘网的设置可以防止异物进入散热通道20内，更有利于保持散热通道20内的清洁。
进一步地，所述底壳20上多个进风口22在加热装置50的长度方向上排布，将多个所述进风口22的排布长度设为L1，加热装置50的长度设为L2，其中，0.5≤L1/L2≤1.1。
本申请技术方案通过在电烤机100的外壳30和内壳10形成散热通道20，并在底壳80开设连通散热通道20的多个进风口22，且多个进风口22在加热装置50的长度方向上线性排列，且将多个进风口22的排列长度L1与加热装置50的长度L2的比值设为0.5≤L1/L2≤1.1，通过上述设置，多个进风口22可满足电烤机100加热食物过程中的散热进风需求，使得电烤机100工作过程中外壳10不会温度过高，一方面可以避免外壳10处于较高温度环境下出现变形老化现象，另一方面可以避免使用者触摸外壳10而被烫伤，则电烤机100的安全性能得到提升。
优选地，多个进风口22于水平面的投影与加热装置50于水平面的投影至少部分重合。如此，由进风口22进入散热风道20并向上方运动的冷风，可迅速且较完全的吸收加热装置50传递至内壳30的热量，并通过出风口24排出。
进一步地，为了降低外壳10的温度，请参照图6和图7，本申请还将内壳30于第二让位口处形成有烤架支撑部35，烤架支撑部35的上端面高于外壳10的上端面。
本申请技术方案烤架支撑部35形成于与内壳30的水平段32连接的板体，通过设置烤架支撑部35的上端面高于外壳10的上端面，可使得电烤机100的烤架70架设于烤架支撑部35时，其侧边缘高于外壳10，这样，即使烤架70在烤制过程中出现较大偏移，其侧边缘也是无法接触到外壳10，从而有效避免了电烤机100的外壳10被烤架70的高温烫坏，保障了电烤机100的结构完好性。
所述烤架支撑部35包括多个，多个烤架支撑部35间隔设置，并环绕第二让位口，两相邻烤架支撑部35之间形成一气流通道37。
具体地，本实施例中，由于第二让位口大致呈长方形，所以，烤架支撑部35设置有四个，且分布与第二让位口的四个角处，以实现对烤架70的四个角的支撑，增加烤架70架设于烤架支撑部35的稳定性及使用安全性。并且，相邻两烤架支撑部35之间间隔，还形成气流通道37，从而有利于内壳30内产生的带有烟雾的热气排出。此外，烤架支撑部35设置还可进一步节省制造材料，降低成本。
本申请，所述烤架支撑部的上端面与所述外壳的上端面的高度差大于0、小于或等于10mm。其中该高度差可优选为大于3、小于或等于10mm，如此，在有效保障电烤机100的结构完好性的同时，还可使得烤架70的位置恰当，内壳30的热量不易传递至烤架70，同时避免了烤架70架设过高所带来了材料浪费，另一方面，还可使得电烤机100的整体更加美观，使用过程中持握烤架70时不易触碰到温度较高的内壳30，如此使用更加安全。
请结合参照图3和图5，本申请的电烤机100为了提高接油盘90的接油效果，接油盘90位于所述烤架70的正下方，且接油盘90于水平面的投影面积和烤架70位于水平面的投影面积大小相当。如此有烤架70上的食物滴落的油脂和水分等均可直接落于接油盘90上。其中接油盘90与底壳80的滑动连接，可以通过在底壳80的两侧设置滑槽，接油盘90的两侧周缘嵌设于滑槽内，并且于外壳10底部设置缺口，接油盘90的端部位于缺口处，通过手动推拉实现接油盘90的端部进出容置腔31，使得电烤机100的清理操作简便。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
