The heat collecting box(17) accommodates multiple ceramic balls(15) of sphere form radiating far infrared when heated. The heat collecting box(17) has peripheral wall to accommodates many ceramic balls(15) and screw holes on three directions on the peripheral wall thereof. The multiple fire holes(21) are formed on a curved surface, formed protrusively upwardly on the bottom surface of the heat collecting box(17), protrusively and slopingly by embossment toward the upper side of the heat collecting box(17). The supporting knobs are more than three in number and engaged with the screw holes to support the heat collecting box(17).
