It should be noted that, in the existing electric oven, the heat insulation tray and the base are directly connected by screws, because the heat insulation tray is made of metal, the base is made of plastic, after long-term use, the position of the heat insulation tray and the base connected by screws is easy to age, so that the heat insulation tray gradually drops and is close to the base, in this application, the heat insulation member 500 made of high temperature resistant molecular material is additionally arranged between the heat insulation tray 300 and the base 100, so that the heat insulation tray 300 is not in direct contact with the base 100, the connection mode of the base 100 and the heat insulation member 500 can be clamped, and the heat insulation tray 300 and the heat insulation member 500 can be detachably connected by bolts. This allows on the one hand to reduce the number of bolts and on the other hand to avoid damaging the base 100. In addition, due to the function of the heat insulation member 500, a preset distance can be formed between the heat insulation tray 300 and the base 100, that is, the heat insulation tray 300 is placed in a suspended manner, so that the situation that the heat insulation tray 300 is close to the base 100 is avoided.
