Definitions

  • the present invention relates to a domestic oven, of the type comprising a cavity provided with a rear interspace within which is installed a fan, the front wall of said interspace being provided with one or more substantially central openings for drawing in air from the cavity and being provided with side openings for circulating the air.
  • the above-stated rear interspace for guiding the air within the cavity is delimited by an appropriately shaped and perforated metal bulkhead and by the back wall of the cavity to which said bulkhead is fixed.
  • the bulkhead not only has the function of holding the circular element for heating the air and the cavity fan, but also of guiding the air produced by the fan through the openings (usually holes arranged in a central circular zone) and through finned openings located at the sides.
  • said solution permits sufficiently even heating of the cavity when the fan is on (when the oven is running in "fan-assisted” mode), the inflowing hot air from the rear bulkhead impinges first on the part of the product being cooked which is closest to the back wall, possibly resulting in uneven cooking.
  • the object of the present invention is to provide an oven of the type specified at the beginning of the description which permits the above-stated shortcoming to be overcome in a straightforward and economical manner.
  • said object is achieved thanks to the fact that the above-stated interspace also extends along the sides of the cavity and is provided with a plurality of openings for circulating the air.
  • sides being taken to mean the side walls or the rear wall, there are installed auxiliary walls in such a manner as to create an interspace extending that created by the rear bulkhead, and which are capable of joining with the latter which, unlike known solutions, is entirely open at the sides.
  • the air exiting from the sides of the bulkhead is driven by the fan into the two side interspaces located against the right hand wall and left hand wall of the cavity, and escapes through a plurality of openings equipped with guide fins. Because said openings are located over the entire surface of the channels, it is ensured that the hot air exits both in the rear zone of the oven (the zone close to the bulkhead) and at the front (close to the door), so allowing the food to be more evenly heated.
  • the guide fins present on the auxiliary side walls which define the interspaces on the side walls of the cavity, apart from directing the air also have the function of supporting the baking trays or shelves given that they are positioned symmetrically on the two sides of the cavity.
  • 10 denotes overall the structure of a built-in domestic oven in which can be seen a front edge 10a for fixing to a cabinet and a cavity 12 within which is located a baking tray 14.
  • the cavity 12 is delimited by a lower wall 12a, by an upper wall 12b, by two side walls 13 and by a back wall of the oven (not shown) on which is affixed a bulkhead 16 which forms the front wall of the rear interspace.
  • auxiliary walls 18 which define the side interspaces connected to the rear interspace.
  • the bulkhead 16 is composed of a substantially C-shaped sheet of metal (Figure 2) in which are defined edges 16a for fixing to the back wall (not shown) of said shell M.
  • Figure 2 In the central portion of the back bulkhead 16, there are a plurality of stamped holes 20 capable of defining a predetermined flow cross-section for drawing air in towards the fan (not shown).
  • the bulkhead 16 is installed on the back wall of the cavity of the oven in such a manner as to define two side openings 22, connected by means of an angled portion 18a, to the auxiliary side walls 18. Alternatively, said connection may be effected by means of inclined portions of the bulkhead 16.
  • Each of said auxiliary side walls 18 ( Figure 3) has folded-back edges 18b to define channels for passage of the air. Furthermore, on a level with each angled portion 18a, each auxiliary side wall 18 has, at the top and bottom, containment portions 18c capable of preventing air escape.
  • the auxiliary side walls 18 are fixed to the shell M of the oven by means of portions 18d arranged substantially on a level with the corners of the rectangular wall.
  • each auxiliary side wall 18 has a plurality of openings 24, rectangular in shape, formed by stamping on three consecutive sides in such a manner as to define an inclined metal tab 24a capable of acting as a guide fin for the air towards the back bulkhead 16.
  • the openings 24 are arranged in several equidistantly spaced horizontal rows in such a manner that the upper edges of the metal tabs 24a can act as supports for baking trays, shelves or the like as indicated in Figures 1 and 4. It is, of course, possible to use supports of conventional design, which are attached in this case to the auxiliary side walls 18 of the interspace, for baking trays or shelves.
  • the openings 24 are also aligned in columns whose spacing changes (decreases) starting from the rear of the cavity towards the opening where the door (not shown) is installed. Said variation in spacing between the columns of openings 24 makes it possible to obtain a substantially identical stream of hot air for each opening 24, so as further to increase the evenness of heating of the food.
  • openings 24 which are equidistantly spaced but are of variable cross-section may be used, the cross-section being at its smallest in the vicinity of the back bulkhead 16 of the cavity and gradually increasing towards the front edge (10a).
  • the use of tabs or fins 24a furthermore makes it possible to minimise any possible soiling of the side interspace defined by the auxiliary walls 18.
