DESCRIPTION
The present invention refers to a high-efficiency energetic plate
which can be preferably placed over a gas burner or the like
for cooking food and/or for uniformly heating pots or the like
put on the pla-te itself.
According to known art, the food cooking and/or the heating of
the pots or the like put on the gas burners of conventional
gas cookers takes place by the direct action of the flame on
the container, or by interposing a conventional irradiating plate.
In most cases, the gas burner is situated under a grate on which
the pots containing the food andjor the containers to be heated
are put. The flame generated by the gas burner touches the pot
bottom directly which causes two inconveniences during the cooking
phases: on the one hand, the food burns where the flame touches
the pot and on the other hand, the combustion fumes are dispersed,
such fumes having a high heat capacity. In addition, there wi.ll
be a series of other inconveniences, caused by the aforesaid
disadvantages, i.e. burn-t food parts wlth raw food parts, nasty
tastes, and above all, molecular alterations in the food with
consequent possible health damages.
Conventional irradiating plates have been produced in order to
overcome such inconveniences These irradiating plates are placed
on the gas burners. In this case, the food is cooked without
a direct flame contact, however there is such a heat loss which
limits the use of this protecting means. In fact, the irradiating
?d ~
-- 2 --
plate acts only as a shield between the gas burner and the pot
and does not take advantage of the hot combustion fumes which
disperse in the air, the heating capacity of the fumes remaining
so unemploy~d.
An object of the present invention is to remove the aforesaid
inconveniences and to provide a high-efficiency energetic plate
which can collect all the heat generated by the combustion
of a gas burner.
To this end, the present plate can use and take advantage
of all the hot fumes of combustion by converging such fumes to the
central cooking, heating area.
Another advantage is that the energetic
plate in question doea not provoke a worsening of the food cooking
processes, as it occurs in using the known plates, on the contrary
the present plate peFmits a kind of cookingwith which excellent
dietetic-alimentary ~alues are obtained.
In addition, the simple structural characteristics of the plate
embodying the present invention permits~ the plate itself to
be produced at very cheap costs and with different sizes and
shapes according to the type of gas burner or container.
Here described is a high-efficiency energetic plate which
can be placed over a gas burner or the like, characterized in
that of consisting of an upper cooking surface, provided
with a central opening from which a series of slots or grooves
starts, such ~-ots or grooves being arranged radially in respect of
_ 3 ~ $
the opening, the upper cooking surface of this plate forming
a sole piece with a perimetrical edge for containing the fumes
generated by the lower flame and for canalizing such fumes
towards the middle opening and the radial grooves; the bottom
of the container to be heated covers the plate and determines
a preferential run of the fumes which pass through the central
opening, go through the radial grooves and finally go out in
the air.
Embodiments of the invention will now be described with reference to
the accompanying draw;ngs in which:
- Figure 1 shows an overall schematic plan view of the energetic plate
embodying the invention;
- Figure 2 shows a schematic sectional vertical view of the entire
apparatus and Figure 2a of the plate, along line A-A of Fig. 1, the plate
being placed over a conventional burner; and
- Figure 3 shows a schematic perspective view of the
plate.
In the drawings, a high-efficiency energetic plate is shaped essentially
as a disc and can be put on a grate 2 of a conventional gas cooker,
over a lower gas burner 3. The plate 1 shows an upper bearing
surface 4 which is interrupted by channellings or grooves 5 which
are arranged radially between a perimetrical edge 6 and a middle
opening 7 which passes through the plate vertically.
The edge 6 extends to a certain extent downwards and forms a
flange 8 which rests on the grate 2 in the present case. If
a hypothetic horizontal circular plane 91, for instance the bottom
of a po-t, is placed on the upper surface of the plate 1, the
fumes generated by the flame form a flow going from the burner
3 to the outside of the plate itself. The fumes of the combustion do
not go straight up, on the contrary the fumes are diverted by
an auxiliary diaphragm 10 which is interposed between the grate
and the plate so that the diverted fumes can heat the whole plate~
At first, the diverted fumes go into the chamber 9 . Then, the
fumes coming from the chamber 9 go through -the middle opening
7 into the grooves 5 which are covered by the bottom 9'of a pot
or the like. The so covered grooves form channels in which the
fumes flow till reaching the edge 6 and the outside.
In such a way, the fume: generated by the com~ustion lap on both
the middle part and the radial bands of the pot bottom before~
dispersing outside in the air. Accordingly, the high temperature
of the fumes is totally exploited so as to make the plate as
efficient as possible.
Moreover, the present plate has a double function, in fact the
plate can be carried out with a different mass according to the
kind of burner and such mass can suitably embody the calories
generated by the flame. Then, the plate is shaped in such a way
~3~
as to take advantage of all the fumes generated by the combustion
which, at first, reach the middle cooking area. Then, the fumes
go from the middle area to the radial bands till reaching the
outside.
The food contained in the pot is not exposed to the direct action
of the flame, however such food absorbs a major part of the
heat of the flame when using the novel plate,
the aforesaid alimentary-dietetic values being safeguarded and
the obtained cooking process being really good.
In the description, only a preferential embodiment of the invention
has b0en described, however it stands to reason that the present
plate can be carried out in any form, shape, size and design,
with one or more middle openings, with a different number and
arrangement of grooves, in any material and for any use; all
these varlants are comprised in the sphere of protection of the
present invention.
Advantageously, tne plate may be fixed or~ not on either the
burner directly or the grate,according to the necessities.
According to a further possible variantt the plate
embodying the present invention may be secured directly on the bottom
of the pot or container to be used. It is also possible to carry
out a pot provided with a plate embodying the present invention,
in which the pot and the plate form a sole piece.
