Cooking oven, comprising a carrying structure that comprises a) at least one elongate bracket extending along an elongation axis as a bearing or carrying part, b) wherein each bracket has at least one bearing surface for bearing or supporting a a side wall of a casing of the cooking oven, c) wherein each bracket has at a lower end thereof at least one hinge bearing surface for bearing or supporting a hinge carrier part of a hinge for a door of the cooking oven, d) wherein each bracket has at least one fastening tab for fastening a treatment container or cavity, and for fastening of a front frame of the cooking oven at the bracket by means of a corresponding frame fastening tab, wherein each bracket is formed as a profiled element extending along the elongation axis and having a profile in a cross section perpendicular to the elongation axis of the bracket, wherein the profile of the bracket, at least over most of the length of the bracket along the elongation axis, is shaped with or around a central edge of the bracket, which central edge extending along the elongation axis, the profile of the bracket comprises at least a front flange and a side flange, extending from the central edge in two directions which are orthogonal to each other, wherein each bracket has at its side flange at least two, preferably three, broadened flange portions (110, 111, 112) extending further away from the central edge and being arranged parallel to the rest of the side flange, wherein each of these broadened flange portions (110, 111, 112) has a bearing surface for a side wall of the casing associated with this bracket, wherein preferably also the not broadened side flange has a bearing surface for the side wall, wherein at least in the broadened flange portions (110, 111, 112) connection means (54, 105) for fixing the side wall are provided, wherein an upper broadened portion of the side flange has a support tab, preferably produced by partly cutting the sheet metal and bending the cut portion inwardly, for supporting a component carrier, in particular for supporting a lateral flange of the component carrier extending downwards, wherein a lower broadened portion of the side flange has a hinge bearing surface for the hinge carrier part and is adjacent to a bottom part of the casing of the cooking oven and is provided with the connection means (54A, 104) for fixing the hinge carrier part to the bracket and with the connection means for fixing the bottom part by means of a front tab of a lateral flange of the bottom part, to the bracket. a) at least one elongate bracket extending along an elongation axis as a bearing or carrying part, b) wherein each bracket has at least one bearing surface for bearing or supporting a a side wall of a casing of the cooking oven, c) wherein each bracket has at a lower end thereof at least one hinge bearing surface for bearing or supporting a hinge carrier part of a hinge for a door of the cooking oven, d) wherein each bracket has at least one fastening tab for fastening a treatment container or cavity, and for fastening of a front frame of the cooking oven at the bracket by means of a corresponding frame fastening tab, wherein each bracket is formed as a profiled element extending along the elongation axis and having a profile in a cross section perpendicular to the elongation axis of the bracket, wherein the profile of the bracket, at least over most of the length of the bracket along the elongation axis, is shaped with or around a central edge of the bracket, which central edge extending along the elongation axis, the profile of the bracket comprises at least a front flange and a side flange, extending from the central edge in two directions which are orthogonal to each other, wherein each bracket has at its side flange at least two, preferably three, broadened flange portions (110, 111, 112) extending further away from the central edge and being arranged parallel to the rest of the side flange, wherein each of these broadened flange portions (110, 111, 112) has a bearing surface for a side wall of the casing associated with this bracket, wherein preferably also the not broadened side flange has a bearing surface for the side wall, wherein at least in the broadened flange portions (110, 111, 112) connection means (54, 105) for fixing the side wall are provided, wherein an upper broadened portion of the side flange has a support tab, preferably produced by partly cutting the sheet metal and bending the cut portion inwardly, for supporting a component carrier, in particular for supporting a lateral flange of the component carrier extending downwards, wherein a lower broadened portion of the side flange has a hinge bearing surface for the hinge carrier part and is adjacent to a bottom part of the casing of the cooking oven and is provided with the connection means (54A, 104) for fixing the hinge carrier part to the bracket and with the connection means for fixing the bottom part by means of a front tab of a lateral flange of the bottom part, to the bracket.
