Abstract

The utility model relates to an electric cooker with a novel heating device. A cooker body of the electric cooker is composed of three layers of base bodies, namely, an outer shell, an inner shell and an inner container. Mainly, an inward-concave wall with a circle of arc-shaped face is arranged on the inner wall of the inner shell. A concave wall of the inward-concave wall is provided with a protruding thermal insulation ceramic block. The thermal insulation ceramic block is connected with a metal fixing clamp. An electric heating pipe is arranged on the metal fixing clamp in a clamped mode. The electric heating pipe is fixed to the metal fixing clamp. The metal fixing clamp and the thermal insulation ceramic block are screwed in the concave wall of the inward-concave wall through screws. Compared with the prior art, a heating disc and the electric heating pipe of the electric cooker can conduct heating independently or simultaneously; the width of an opening is increased due to the inward-concave wall with the arc-shaped face, heat dissipation is uniform, the heated area of the outer wall of the inner container is enlarged, and therefore food in the inner container can be rapidly cooked; the electric heating pipe is arranged in the inward-concave wall so that the metal inner container or the ceramic inner container in the universal size can be used, and damage caused when the inner container is frequently taken out and placed and collision happens to the inner container can be prevented.
