Electric heating device based on solid heat storage and phase change heat storage

The invention relates to the technical field of heating and energy saving, in particular to an electric heating device based on solid heat storage and phase change heat storage, which comprises a magnesite brick heating module, a phase change heat storage module, a heat energy conversion module and a heating control module, provides two heating modes of hot water heating and hot air heating, and can utilize valley price electricity to store heat for heating. And releasing heat for heating in a non-valley-price electricity period. In the heat storage mode, the magnesite brick stores heat, meanwhile, hot air exchanges heat with the heat conduction medium at the fin type heat exchanger, the heat conduction medium transfers heat to the phase change heat storage material and flows to the heat exchanger for heat exchange, and heating use is met. In the heat release mode, the heating control module controls the heat storage and release sequence according to the temperature of the magnesite bricks, and heat can be ef
