Abstract
The invention discloses a protective cover of a roasting pipe, which is arranged under the roasting pipe at the top of a microwave oven cooking cavity. The protective cover of the roasting pipe comprises a mesh-shaped metal protective net and a plurality of reflecting plates fixedly arranged on the same side of the protective net. The protective net structure enables microwaves to be unable to transmit the protective net and avoids sparking when the microwaves meet with a carbon tube. Simultaneously, the mesh-shaped protective structure of the protective net enables infrared radiation emitted by the roasting pipe to transmit the protective net to act on foods to the most extent. The reflecting plates fixedly arranged on the protective net further reflect heat radiation emitted by the roasting pipe to the whole cooking cavity, thereby improving radiation efficiency of the roasting pipe and roasting effect simultaneously.
