Definitions

  • the present invention refers to a cooking oven with a muffle.
  • a muffle (M) oven for cooking food comprises a substantially cubic or otherwise parallelepiped shaped body or alike, wherein is defined the cavity for cooking food frontally closed by a door, this last being usually hinged to the muffle with vertical or horizontal axis depending on the various solutions.
  • the muffle M Around the muffle M is then applied the insulating material to isolate it thermally and all other components that complete the oven, namely the conduits of the gas and / or electrical wirings, the ventilation fan (when provided), commands, various circuits and so on.
  • the support bracket S is typically fixed to the rear wall of the muffle M through fixing screws.
  • This kind of fixing has the drawback to concentrate in the area around the holes of the muffle M the weight of the muffle and the stresses that come from this (for example when the oven is moved). Therefore, the muffle M must be sufficiently robust so that will not be damaged.
  • a way to avoid this drawback consists in the implementation of a muffle M using a material of greater strength and /or a metal sheet of greater thickness than the one utilized in an oven solely composed of a muffle. In this way, however, the weight and/or the cost of the muffle M are increased.
  • the basic idea of the present invention is to provide an oven in which the side panels of the structure are fixed directly to the muffle, in order to make unnecessary the bracket or other similar objects.
  • fig. 1 illustrates a perspective view of an oven muffle according to the prior art
  • fig. 2 illustrates a front view of a muffle according to the invention
  • fig. 3 illustrates a top view of the muffle of Fig. 2;

  • fig. 5 illustrates a view of detail A of Fig. 4;
  • fig. 6 illustrates a view of detail B of Fig. 4.
  • an oven comprises a muffle 1 in which a cavity, or cooking chamber, is delimited by a pair of side walls 2,3, a rear wall 4, a bottom wall 5 and a top wall 6.
  • the walls can be realized according to any known way in the art, for example a piece molded, bended or other worked metal sheet.
  • the side walls 2, 3 and the rear 4 are in one piece, whereas the bottom 5 and the top wall 6 are fastened with the walls 2,3,4 by constraint means (i.e.: welds, rivets, etc.).
  • the oven also includes a pair of padding panels 7,8 which are positioned at the sides of the muffle 1, in order to advantageously allow the application of the insulating material around the muffle 1.
  • the side panels 7 and 8 are fixed to the muffle 1 through fastening means, better below described.
  • the upper wall 6 comprises a peripheral flange 41 which extends along its rear edge, and preferably also along the side ones; the flange 41 protrudes with respect to the rear wall 4 and, in correspondence of the rear corners, presents some folds 42 folded like an "L" .
  • Each one of the external panels 7, 8 has an inward folded rear edge, 71 and 81, so to advantageously facilitate the coupling between said panels 7, 8 and folds 42 of the top wall 6. Furthermore, the folded rear edge 71, 81 of the panels 7, 8 presents some deep-drawings that increase advantageously the rigidity.
  • each folded edge 71, 81 of the panels 7, 8 comprises holes 73, 83 that allow the coupling of the respective lateral panel 7,8 with the muffle 1.
  • the flange 41 comprises at least two folds 42, positioned in the near of the ends of the rear wall 4.
  • Each fold 42 has folded form preferably as a "L" and includes at least one hole 43 which is aligned with the hole 73, 83 when the side panel 7,8 is coupled with the muffle 1 , in order to allow the use of the fixing means , such as screws, bolts, rivets or other, to fasten stably the coupling between the panel 7,8 and the muffle 1.

Abstract

L'invention se rapporte à un four qui comprend un moufle (1) ayant une structure externe, où les panneaux latéraux (7, 8) sont fixés à un rebord (41) qui fait saillie depuis le moufle (1). De manière avantageuse, le rebord est situé sur la paroi supérieure (6) ou sur la paroi inférieure (5) du moufle et, au niveau des coins, présente des plis (42) qui facilitent la fixation des bords pliés aux panneaux latéraux. De cette manière, les panneaux sont fixés directement au moufle, ce qui permet d'éviter la fixation de certaines pièces telles que des équerres et analogues.
