Abstract

A plate for location over a gas burner comprises an upper surface (4) capable of receiving a container for food to be cooked, the upper surface defining a central aperture and a plurality of channels or grooves (5) which extend radially outwardly from said central aperture. The plate may be integrally formed with or affixed to the base of a cooking container.

Description

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 plate 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 ihterposing a conventional irradiating plate.

In most cases, the gas burner is situated under a grate on which the pots containing the food and /or 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 will be a series of other inconveniences, caused by the aforesaid disadvantages, i.e. burnt' food parts with 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 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 unemployed.

The aim of the present invention is to remove the aforesaid inconveniences by carrying out 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 of the present invention is that the energetic plate in question does not provoke a worsening of the food cooking processes, as it occurs in using the known plates, on the contrary the present plate permits a kind of cooking with which excellent dietetic-alimentary values are obtained.

In addition, the simple structural characteristics of the plate according to 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.

The invention relates to 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 slots or grooves being arranged radially in respect of /E 904107 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.

The invention will be better comprised from the following description, set out as an example which does not limit the invention itself as well as from the accompanying drawings in which: - Figure 1 shows a schematic plan view of the energetic plate according to the invention as a whole; - Figure 2 shows a schematic sectional vertical view of the plate, according to line A-A of Fig. 1, the plate being placed over a conventional burner; and - Figure 3 shows a schematic perspective view of the present plate.

With reference to the accompanying drawings, number 1 indicates a high-efficiency energetic plate according to the invention as a whole. In the present example, the 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 9*, for instance the bottom of a pot, is placed on the upper surface of the plate 1, the fumes generated by the flame form a flow going from the burner 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 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 fumes generated by the combustion 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 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 a food absorbs all the calories of the flame when using the plate according to the present invention, 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 been 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 variants are comprised in the sphere of protection of the present invention. Advantageously, the plate may be fixed or not on either the burner directly or the grate, according to the necessities.

According to a further possible variant, the plate according to 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 according to the present invention, in which the pot and the plate form a sole piece.

Claims
