AI Technical Summary

Technical Problem

The length of existing microwave oven waveguides is relatively long, resulting in a long microwave transmission distance, resulting in large microwave transmission losses, which can easily cause microwave focus ignition and local temperature increase.

Method used

By setting the microwave generator and the waveguide on the same side of the inner liner, the length of the waveguide channel is shortened, the microwave transmission loss is reduced, and an adjusting convex hull that protrudes inwardly in the waveguide channel is set to adjust the electric field distribution and improve the transmission performance.

Benefits of technology

It effectively shortens the transmission distance of microwaves, reduces the loss during microwave transmission, improves the utilization rate of energy, and makes the microwaves more evenly distributed in the cooking space.
