Description
FIELD OF THE INVENTION
[0001] The present invention refers to an oven and, more
specifically, a domestic oven for cooking/heating up miscellaneous
foods.
[0002] The present invention also refers to a kitchen oven that
comprises the aforementioned oven.
BACKGROUND OF THE INVENTION
[0003] 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.
[0004] An oven's cooking cavity, in turn, 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.
[0005] In the same way, 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. Also, 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.
[0006] 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.
[0007] It is known that the material used in the oven's internal
cavity directly influences its durability and performance, mainly
with regard to corrosion resistance, thermal reflectivity and
consumption, which is directly influenced by the oven's operating
efficiency.
[0008] In particular, the internal cavity of currently known ovens
is normally built from steel, which has an enameled coating in
order to prevent corrosion. Generally speaking, 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". Moreover, 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.
[0009] That kind of coating is consequently also known as
"self-cleaning". One should note that the rear wall (back) may be
of both the "easy clean" type and also of the "self-cleaning" type,
depending on the oven's type and application.
[0010] However, in spite of the fact that these known coatings
provide the oven with functional and aesthetic benefits, they
require an additional stage in the production process, enameling,
which raises the oven's manufacturing costs, which is obviously
undesirable.
[0011] There is thus a need for a technical solution for ovens'
internal cavities, which is capable of simultaneously providing
durability, performance and low production cost.
OBJECTIVES AND DESCRIPTION OF THE INVENTION
[0012] Therefore, 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.
[0013] In addition, 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.
[0014] 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.
[0015] Moreover, 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.
[0016] It is also an objective of the present invention to provide
a domestic oven, in particular for cooking/heating up food, with a
construction layout that dispenses with the enameling stage on at
least one wall of the internal cavity, allowing the reduction of at
least one of the stages of production and, consequently, a
reduction in production costs.
[0017] Lastly, it is also an objective of the present invention to
provide a kitchen oven that comprises the aforementioned oven.
[0018] One or more of the aforementioned objectives of the present
invention, among others, 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.
[0019] In accordance with additional or alternative embodiments of
the oven of the present invention, it may also comprise the
following characteristics, alone or in combination:
[0020] the set of walls comprises an upper wall, a lower wall, a
rear wall and side walls;
[0021] the wall of the internal cavity that comprises carbon steel
coated by said alloy made of Zinc, Aluminum and Silicon is the
upper wall;
[0022] said alloy comprises between 35% and 50% of Zinc;
[0023] said alloy comprises between 50% and 60% of Aluminum;
[0024] said alloy comprises between 1% and 2% of Silicon;
[0025] said alloy comprises between 35% and 50% of Zinc, between
50% and 60% of Aluminum and between 1% and 2% of Silicon;
[0026] said alloy comprises 43.5% of Zinc, 55% of Aluminum and 1.5%
of Silicon.
[0027] 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.

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.
[0033] In particular, 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. Alternatively, 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.
[0034] In a more particular manner, 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.
[0035] It is worth noting that the carbon steel coated by the alloy
