The electric oven is mainly composed of a box, an electric heating element, a thermostat, a timer and a power adjustment switch. The box body is mainly composed of an outer shell, an intermediate layer and an inner liner, which forms a three-layer structure. The front and rear edges of the inner liner form curling edges to cut off the air in the cavity; the outer cavity is filled with insulating expanded perlite products to make the outer shell. The temperature is greatly reduced; at the same time, a spring structure is installed under the door, so that the door is always pressed on the door frame, so that it has better sealing performance.
