Internal Heating Characteristics of the Xiaomi Microwave Oven
Different from conventional heating, microwave heating is a kind of internal heating, that involves an energy conversion from the electromagnetic energy to thermal energy rather than the heat transfer. Microwave energy is delivered directly to the material through molecular interaction with the electromagnetic field. Since microwaves can penetrate the material and supply energy, heat can be generated throughout the volume of the material resulting in volumetric heating. Besides, the oven door is sealed when overheating, which results in an insulated environment that lacks the possibility of heat dissipation. Therefore, the internal temperature is higher than the external temperature, and the vapor pressure difference drives the internal water to penetrate the surface, accelerating the migration of water evaporation rate.
