Description

technical field [0001] The invention relates to a heating device, in particular to a rapid heating device based on microwave energy capture. Background technique [0002] In recent years, the application of microwave heating has become more and more widespread. It will be a very meaningful work to improve the conversion efficiency of microwave energy and reduce the electromagnetic pollution of microwave heating devices. [0003] For example, existing microwave oven heating containers are usually made of ordinary materials such as glass, ceramics, and plastics. They mainly play the role of bearing objects in the microwave oven cavity. Microwave energy directly passes through the container and oscillates back and forth inside the microwave oven cavity. The reflection produces the basic mode and various higher-order modes in the microwave cavity, and the entire cavity is unevenly filled with microwave energy, and part of it is reflected back to the magnetron and leaks to the ou...
