Abstract

The invention discloses a microwave surface wave uniform heating device for microwave ovens. At least two feed structures in the middle. The technical scheme of the present invention has a higher longitudinal surface wave height and is less affected by the metal reflection at the top of the microwave oven cavity, so that the energy distribution in the oven cavity is more uniform, the heating efficiency is further improved, and the heating time is shortened.

Description

technical field [0001] The invention belongs to the technical field of microwave heating equipment, and in particular relates to a microwave surface wave uniform heating device for microwave ovens. Background technique [0002] Since the advent of microwave ovens, it is now a must-have in almost every home kitchen. However, with the rapid development of technology, people's further pursuit of quality of life puts forward higher requirements for the heating efficiency of microwave ovens. As we all know, microwave ovens use the interaction between electromagnetic waves and food molecules to achieve the purpose of heating. Specifically, when an external electric field interacts with food molecules, the molecules are polarized. When the frequency of electromagnetic waves is low, the polarization direction of the molecules changes with the direction of the electric field. When the frequency of the electromagnetic wave is high, the change of the molecular polarization direction...
