Upper cover assembly and frying and baking machine

The invention discloses an upper cover assembly and a frying and baking machine, the upper cover assembly comprises a cover body, a light wave tube and a multi-layer window structure, and the light wave tube is connected to the cover body; the multi-layer window structure is arranged on the cover body, and a light-transmitting heat insulation cavity is defined between the multi-layer window structure and the cover body. According to the technical scheme, the temperature of the outer surface of the multi-layer window structure is reduced, so that a user is prevented from being scalded by the high temperature of the outer surface of the multi-layer window structure, and the use convenience and safety of the frying and baking machine are improved. 本发明公开一种上盖组件和煎烤机，其中，上盖组件包括盖体、光波管以及多层视窗结构，光波管连接于盖体；多层视窗结构设于盖体，多层视窗结构与盖体之间围合形成透光隔热腔。本发明技术方案旨在降低多层视窗结构的外表面的温度，以避免用户被多层视窗结构的外表面的高温所烫伤，提高煎烤机使用的便利性和安全性。
