Definitions

  • the present invention refers to an oven and, more specifically, a domestic oven for cooking/heating up miscellaneous foods.
  • the present invention also refers to a kitchen oven that comprises the aforementioned oven.
  • Ovens are domestic and industrial utensils that are rather well-known and essential for preparing food. Individual ovens, i.e. those in which there is just the cooking cavity, are known, as are ovens that are part of kitchen ovens, having one or more burners that are combined with an oven, the latter generally disposed underneath the kitchen oven top.
  • An oven's cooking cavity generally comprises a parallelepipedal format with five fixed walls, one of the sides having a removable wall, such as a door, through which it is possible to gain access to the inside of the cavity.
  • the walls may also comprise a thermal coating in order to prevent dissipation of the heat generated inside the cavity, as well as an opening to remove the gas and heat generated in the cavity, in order to offset the internal temperature and pressure.
  • different sources of radiation may be used to generate heat inside the oven cavity or directly in the food, such as but not limited to burning gas, use of electrical resistance, generating microwaves, hot steam, etc.
  • more than one source of heat may be associated in the same oven, such as a combination of a gas oven with electrical resistance, a microwave oven with electrical resistance, etc.
  • the domestic kitchen ovens for cooking food known in the state of the art comprise a set of burners at the top and at least one oven underneath said burners.
  • the internal cavity of currently known ovens is normally built from steel, which has an enameled coating in order to prevent corrosion.
  • the upper wall (top) and the lower wall (base) of the oven's internal cavity are coated with an enamel with a smooth texture that is easy to clean, preferably of the smooth vitrified type, also known as "easy clean”.
  • the side walls of the oven's internal cavity normally have an enameled coating with a rough, porous surface, which is capable of absorbing grease so as to dispense with the need for cleaning.
  • That kind of coating is consequently also known as "self-cleaning".
  • the rear wall may be of both the “easy clean” type and also of the “self-cleaning” type, depending on the oven's type and application.
  • one objective of the present invention is to provide an oven for cooking/heating food that is capable of eliminating or at least reducing the limitations of known technologies in the state of the art.
  • a further objective of this present invention is to provide a domestic oven, in particular for cooking/heating up food, which presents enhanced resistance to corrosion at high temperatures compared with ovens known in the state of the art.
  • Another objective of the present invention consists of providing a domestic oven, in particular for cooking/heating up food, which presents an enhanced thermal reflectivity index compared with ovens known in the state of the art.
  • Another objective of the present invention consists of providing a domestic oven, in particular for cooking/heating up food, which presents more efficient operation, so as to provide lower gas consumption compared with ovens known in the state of the art.
  • One or more of the aforementioned objectives of the present invention is/are achieved through an oven with at least one internal cavity provided with a set of walls, at least one wall of the internal cavity comprising carbon steel coated by an alloy made of Zinc, Aluminum and Silicon.
  • the oven of the present invention may also comprise the following characteristics, alone or in combination:
  • This present invention also refers to a kitchen oven that comprises a set of burners and at least one oven as described above, the oven being disposed under said set of burners.
  • domestic oven 1 object of the present invention, will be described below in accordance with particular, but not limiting, embodiments, since their specific features may be embodied in different forms and variations in accordance with the desired application. It is also worth pointing out that domestic oven 1, with a particular shape, is designed for use in homes.
  • oven 1 as a domestic oven, comprises at least one internal cavity 2 capable of accommodating miscellaneous foods during the process of cooking/heating up.
  • This internal cavity 2 of oven 1 has a set of walls 3, 4, 5, 6, 7 that comprises an upper wall 3, a lower wall 4, a rear wall 5 and side walls 6, 7, at least one of these walls of the internal cavity 2 comprising carbon steel coated by an alloy made of Zinc, Aluminum and Silicon.
  • the wall of the internal cavity 2 which comprises carbon steel coated by the alloy of Zinc, Aluminum and Silicon is the upper wall 3.
  • any of the walls in the set of walls 3, 4, 5, 6, 7 may, separately or in combination, comprise carbon steel coated by the alloy of Zinc, Aluminum and Silicon.
  • said alloy comprises between 35% and 50% of Zinc and/or between 50% and 60% of Aluminum and/or between 1% and 2% of Silicon. More specifically, said alloy comprises 43.5% of Zinc, 55% of Aluminum and 1.5% of Silicon.
  • the carbon steel coated by the alloy of Zinc, Aluminum and Silicon in particular in the aforementioned proportions, provides the internal cavity 2 of the domestic oven 1 with enhanced corrosion resistance at high temperatures, an enhanced thermal reflectivity index and greater operating efficiency (lower gas consumption) compared to domestic ovens known in the state of the art.
  • the construction layout of domestic oven 1 of the present invention also dispenses with the enameling stage for at least one wall in its internal cavity 2, which allows it to lower production costs.
  • the proposed technical solution thus provides domestic oven 1 with durability, performance and low production cost.
  • a further object of the present invention is a kitchen oven comprising a set of burners and at least one domestic oven 1 as described above, the domestic oven 1 being disposed under said set of burners.
  • the domestic oven and kitchen oven of the present invention may be embodied in different manners and may present modifications to the manner of their implementation, such that the extent of the invention's protection is limited solely by the wording of the attached claims, including all possible equivalent variations.
