PURPOSE:To utilize effectively heat efficiency by a method wherein venting holes are holed on the overhanging part curved toward external oblique upper direction from the upper side of a hollow cylinder, and the overhanging part is bent toward the internal side in horizontal direction. CONSTITUTION:An overhanging part 5 is formed by bending the upper part of a hollow cylinder 4 toward oblique upper direction. The horizontal body H is formed by bending the extended part of the overhanging part 5 to the desired length toward the internal side in horizontal direction. Venting holes 6 are holed on the periphery part of the overhanging part 5. Fitting screws 7 having projections 8 on the top thereof are screwed into the lower part of the overhanging part 5, also the fitting screws are served for the positioning of a pan and the like. A trivet 9 placed around a burner 2 on the cooking stove base 1 is served for placing the pan and the like. |
