The invention relates to a heat accumulating type electric heater, and by means of the heat accumulating type electric heater, the technical problems that an existing heat accumulating type electric heater cannot accumulate or release heat automatically and cannot switch the working modes according to different power consumption conditions are solved. The heat accumulating type electric heater comprises a heat preservation shell and a heat dissipation shell which are connected together; an upper heat accumulating brick layer and a lower heat accumulating brick layer are arranged in the heat preservation shell, heating bars are connected between the two heat accumulating brick layers, and the upper heat accumulating brick layer and the lower heat accumulating brick layer form a whole heat accumulating layer; the heat dissipation shell is provided with heat dissipation holes and connected with an air blower; the heat accumulating type electric heater further comprises a controller and aheat accumulating layer temperature sensor, the controller is connected with the heat preservation shell, the heat accumulating layer temperature sensor is connected with the heat accumulating brick layer, and the signal output end of the heat accumulating layer temperature sensor is connected with the controller; and the heating bars are connected with the controller. The heat accumulating type electric heater is widely applied to the technical field of heating.
