Definitions

  • This utility model relates to a fan-assisted oven in accordance with the introduction to the independent claim.
  • the rear wall of the cooking chamber is known to comprise, in addition to the central grille, one or more slots in its edges close to the other walls of said chamber (in particular the side walls). Air heated by the resistance element and forced by the fan penetrates through these slots into the cooking chamber and flows along its walls, to be then drawn towards the fan through the central grille.
  • Other slots are also provided in the rear wall such as to also direct the hot air forced by the fan towards a central region of the cooking chamber.
  • An object of the utility model is to provide a fan-assisted oven in which the drawbacks of known ovens are overcome.
  • a particular object of the utility model is to provide a fan-assisted oven in which there is a better distribution of hot air within its cooking chamber so as to improve the preparation quality of the food and in particular of a plurality of food items positioned at different levels within the oven.
  • a further object is to provide an oven of the stated type in which the food is not directly struck by the hot air flow, so preventing non-uniform preparation.
  • a fan-assisted oven ie in which forced air circulation is created
  • a cooking chamber 2 defined by side walls 3 and 4, a roof 5, a lower wall 6 and a rear wall 7, it being open frontally at 8.
  • a usual movable door On this open side there is provided a usual movable door, not shown.
  • usual guides 10 On the walls 3 and 4 there are positioned usual guides 10 for supporting known shelves and grids, not shown.
  • a compartment 11 containing in known manner a usual fan 12 driven by its own electric motor 13 and arranged to generate said air circulation within the chamber 2, and a known electrical resistance element 14 arranged to heat the air moved by the fan.
  • a grille portion formed as the central part of the wall 7.
  • the slots 18 can be of identical dimensions (such as those to the right for example in Figure 3) or of different dimensions (such as those to the left for example in Figure 3). In this latter case, the slots 21 positioned at the geometrical corner 20 of the wall 7 and in its immediate vicinity are of greater dimensions than the remaining slots to facilitate the said air circulation (ie so that each air stream leaving the slots 18 follows substantially the edges 19 of the chamber 1).
  • the utility model results in a better hot air distribution within the cooking chamber 2 (with considerable advantages in the preparation of the food and in particular of food items positioned simultaneously on different shelves within this chamber); in addition the air emitted by each corner slot 18 does not directly strike the food within the oven, so preventing different degrees of preparation (for example cooking) of different parts of one and the same food item.
  • Figures 4 and 5 represent a modified embodiment of the oven of Figures 1 to 3.
  • parts corresponding to those of the already described figures are indicated by the same reference numerals.
  • the wall 7 comprises a flat portion (in which the grille portion 16 is formed), from the upper and lower parallel sides 71 and 72 of which there extend two bent parts 73 and 74 arranged to cooperate with a back panel 75 defining with the wall 7 the compartment 11 housing the fan 12.
  • the parts 73 and 74 extend along only part of the sides 71 and 72 so that in conjunction with the side walls 3 and 4, the lower wall 6 and the roof 5, they define passages 77 positioned along the edges 19 of the cooking chamber 2.
  • these passages are provided only along said sides 71 and 72 of the well 7, but can also be provided along the vertical sides 78 and 79 ( Figure 4) of this latter in proximity to the walls 3 and 4 of the chamber 2 (in other words they can embrace the corners 20 of the wall 7).
  • the sides 78 and 79 are bent towards the back panel 75 of said chamber and rest against it.
  • the corner passages provided in the wall 7 enable a forced air circulation to be achieved (arrows W of Figure 4) along said edges 19 of the chamber 2.
  • FIG. 6 shows schematically the air circulation within the oven 1.
  • the forced air fed into the chamber 2 via the corner entry regions penetrates within the chamber 2 along its edges and on striking the door is deflected (arrows P) towards the central region of this chamber and drawn (arrows T) into the compartment 11 via the grille portion 16 by the fan 11.
