PURPOSE:To prevent the change of height of cooking material in either case of putting the cooking material on the surface of front or rear of a cooking rack as well as the generation of spark by a method wherein the supporting units of the cooking rack are formed independently by separating them into the supporting unit being inscribed with the supporting piece of a heating chamber and the same unit being circumscribed with the supporting piece of the heating chamber. CONSTITUTION:The location in front-and-rear direction of the cooking rack 9, being put on the supporting pieces 8 of the heating chamber, is determined by the circumscribed sections 11a, 11b being circumscribed with the supporting pieces 8 and a space between the wall surface 2 of the heating chamber 1 can be kept surely whereby the spark between them is not generated. On the other hand, the opposite surface of the cooking rack 9 is placed so as to keep it in upper side, the location of the cooking rack in front-and-rear direction is determined by the inscribed sections 12a, 12b being inscribed with the parts 13a, 13b of the supporting pieces 8 and the space of the heating chamber 1 between the wall surface 2 may be kept in the same manner whereby the spark will never be caused. |
