Protective cover of roasting pipe

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.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a protective device for a microwave oven baking tube. Background technique [0002] A microwave oven is a device that generates microwaves from an electric current and irradiates the microwaves to the surface of the object to be heated in the cavity to heat the object. As everyone knows, microwave oven is a kind of modern cooking stove that heats food with microwave. The microwave it uses is a kind of electromagnetic wave. The energy of this electromagnetic wave is not only much greater than that of ordinary radio waves, but also has special characteristics. When the microwave hits metal, it will reflect, and the metal has no way to absorb or conduct it; microwave can pass through insulation such as glass, ceramics, and plastics. Materials, but will not consume energy; and food containing water, not only can not pass through the microwave, but its energy will be absorbed. Based on these cha...

Problems solved by technology

[0005] In the prior art, during the operation of microwave ovens, especially when grilling and microwave work at the same time, the microwave will spark when encountering the grilling tube. The sheet-shaped blocking structure is adopted, although most of the microwave radiation is blocked, it also greatly reduces the grilling tube. radiation efficiency; and the barbecue tubes are generally set to two or three, resulting in uneven heat distribution in the oven cavity, prone to partial undercooking or scorching
