Abstract: A casing for electric stoves includes an annular frame and a bottom board that are detachably coupled through a plurality of connectors. The frame has at least one lateral side with an air convection means located thereon. The bottom board has an upper surface with a heat control means installed thereon. Through the detachable bottom board, the entire electric stoves need not to be disassembled or removed when malfunction occurs and needs repair. By separating the bottom board from the frame, the electric link between the heat control means and the electric stove can be disconnected to replace the heat control means. Thus the malfunction can be fixed quickly, and interruption or delay of cooking that might otherwise happen can be prevented.
