Abstract:
PROBLEM TO BE SOLVED: To reduce deformation due to heat, permit containing in a small space and increase heat efficiency as well as safety property by a method wherein a cylindrical peripheral wall is constituted of a double-wall structure having cavities. SOLUTION: A combustion chamber unit 19 and a flame guiding chamber unit are provided with a peripheral wall, faced toward outside, and a partitioning plate for making cavities. Respective peripheral walls are cylindrical respectively and retain the cylindrical shapes without being deformed at a high temperature. The lower peripheral wall 2 and the lower partitioning wall 7 of the combustion chamber unit 19 are made so as to be high while the combustion chamber unit 19 is provided with a configuration that the thickness of the upper peripheral wall and the partitioning wall can be received in the lower half upon storage. The upper end of the lower partitioning wall 7 of the combustion chamber unit 19 is provided with an angle so that the inside of the end is elevated whereby current of flame, concentrated to a pot (kettle), is produced. The height of the upper partitioning wall in the flame guiding chamber unit is constituted so as to be slightly lower than the height of the upper peripheral wall whereby the flow of flame ascends once to the vicinity of the flange of the pot (kettle) from the bottom part of the same and, thereafter, descends along the cavity unit while riding over the upper end of the partitioning wall and is discharged to the outside from an exhaust port. Accordingly, heat in the flame stays in the upper part of the cooking stove and waste gas is discharged whereby the heat absorption rate of the pot (kettle) is increased.
