Description

一种烤箱微波炉一体机 技术领域
本发明涉及厨房设备的技术领域，尤其是一种烤箱微波炉一体机。
背景技术
微波炉是一种用微波加热食品的现代化烹调器具，就是用微波来煮饭烧菜。微波是一种电磁波，微波炉由电源、磁控管、控制电路和烹调腔等部分组成。电源向磁控管提供大约4000伏的高压，磁控管在电源的激励下，连续产生微波，再经过波导系统，耦合到烹调腔内。在烹调腔的进口处附近，有一个可旋转的搅拌器，因为搅拌器的叶片由金属片和云母片制成，旋转起来以后对微波具有各个方向的反射，所以能够把微波能量均匀地分布在烹调腔内。
电烤箱是一种密封的用来烤食物或烘干产品的厨房电器，通常家用烤箱可以用来加工一些面食，如面包、披萨、蛋挞、小饼干等，还有些烤箱可以烤鸡肉，做出的食物通常香气扑鼻。电烤箱主要由箱体、内腔、发热元件、温度控制器、定时器、烤盘、烤网等组成。发热元件有用金属管状电热元件的，有用乳白石英玻璃加热元件的，也有用片状远红外辐射电热元件的。面板上的温度控制器是电烤箱的控制系统，并由红、绿色指示灯显示其工作状态。
随着技术的发展以及对厨房空间的有效利用，现已有将微波炉和烤箱制成一体机的产品，这种既有微波加热功能、又同时具有烘烤功能的一体机产品，在加热食物的过程中，特别是单独使用烘烤功能时候，必须要将加热元件的热量有效传递给烹饪炉腔，同时还要避免加热元件产生的热量散失而影响其他电子元器件，并且烘烤食物时，会产生大量热汽，因此必须要在烹饪炉腔上开设与外部连通的蒸汽出口，才能保证烹饪炉腔内的气压与外界保持平衡畅通，否则会存在使用安全事故。但是，蒸汽出口的设置，当产品使用微波加热时，会存在微波泄漏的风险。另外，蒸汽入口的设置，也存在微波泄漏的风险。

该烧烤发生装置包括设置在烹饪腔体1背部(即炉体10的背部)的背部发热装置，设置在烹饪腔体1底部(即炉体10的底部)的底部发热装置，及设置在炉体10中位于烹饪腔体1内上部的上加热元件，上加热元件为加热管。
其中，如图8所示，背部发热装置包括：
背部热风室盖51，固定在烹饪腔体1背面的热风挡板24上，并与烹饪腔体1热风挡板24之间形成有封闭的热风室A；

加热元件62外覆盖有底部保温棉层63。
所述微波发生装置包括波导管31、磁控管32、高压变压器33和高压电容34，波导管31安装在烹饪腔体1底部，高压变压器33和高压电容34为磁控管32提供电源，磁控管32产生微波，波导管31的出口通过微波入口与烹饪腔体1相连通，波导管31的入口与磁控管32相连通，高压变压器33和高压电容34安装在烹饪腔体1上方，在 波导管31外侧安装有对磁控管32进行散热的风扇7，烹饪腔体1上方安装贯流风机8，用于对烹饪腔体1内排出的热风进行冷却，同时对上方的电子元器件进行散热。
