Description

Title: `` HIGH PERFORMANCE OVEN FOR COOKING FOOD ''

FIELD OF APPLICATION

The present invention relates to a high-performance multi-deck oven for cooking food. The oven in question is of the flame and / or electric type and / or other forms of heating and its main feature is the possibility of using various cooking hobs, each of which can possibly also be rotating and translatable in height.

More particularly, the present invention refers to a high efficiency multi-deck oven provided with several floors, one of which, some or all of which may be rotating, possibly equipped with a lift system, or even possibly with both combined systems, obtaining a construction that allows to achieve a variety of performances, applications and functions suitable for cooking, even at the same time, different types of foods.

Basically it is a multi-hob oven working with wood, and / or gas, and / or pellets, and / or electricity, with direct flame cooking (the combustion flame is in the same cooking chamber), where the hobs can be two or more, and can also be rotating and equipped with a lifting movement.

In the various versions, the oven can have hobs that are not rotating but with lifting movement, only rotating, stationary or fixed (no lifting no rotating) or a combination of all.

The present invention generally finds application in the field of cooking devices, as in that of ovens for cooking both industrial and domestic foods.

STATE OF THE TECHNIQUE

As has been known since ancient times, the oven has always been used for cooking foods and foods of various kinds.

There is a known existence of a particular type of direct cooking rotary oven, called â € œup & downâ € for the characteristic lifting movement of the shelf, as well as rotating ovens without lifting movement, operating with wood, gas, pellets, electricity.

There are also static ovens with a cooking chamber and a combustion chamber placed on different levels, and more specifically the cooking chamber is located in the part above the combustion chamber. Since the two chambers are not in communication with each other, the cooking products do not see the flame and neither do they enjoy the direct heat produced by combustion, which therefore provides indirect cooking.

Examples of these ovens can be constituted by the old wood-burning ovens for baking bread, also built today, the ovens of the wood-burning stoves with cast iron rings, subsequently transformed to gas, which were found in every home, or the most current wood or pellet stoves that have obtained a small oven in the upper part and exploit the heat of the fumes to heat it.

In all the cases described, the fire or the combustion fumes do not come into contact with the cooking foods, therefore they are always indirect cooking ovens.

To date, a direct cooking oven has not been designed and built that allows food to be cooked on several levels at the same time, nor by using rotating and / or height-shifting hobs, therefore still today there are limits in carrying out culinary variations by the user.

DESCRIPTION OF THE INVENTION

The present invention proposes to provide a direct cooking multi-level oven with high qualitative and quantitative efficiency for cooking food.

The invention also proposes to provide a multi-level direct cooking oven which is relatively simple to build so as not to be excessively expensive to produce.

This is achieved by means of a direct cooking multi-level oven whose characteristics are described in the main claim.

The dependent claims of the solution in question outline the advantageous embodiments of the invention.

The main advantages of this solution concern first of all the fact that the use of the multi-level oven with direct cooking, exploiting the physical capacity of the heat to go upwards, allows the use of cooking zones at different temperatures for each level, allowing , according to the invention, to cook at different temperatures for each level.

This allows to exploit the heat in an optimal way with a high relationship between different types of food being cooked and the heat produced.

The multi-level direct cooking oven according to the invention is therefore substantially constituted by an upper body generally with a dome shape or other more suitable conformation, inside which several cooking surfaces are arranged on different levels.

According to the invention, some versions of the oven are provided, including the one according to which the oven is provided with at least one of the shelves with the characteristic of being non-rotating but vertically movable, and / or that the oven is equipped with at least one of the hobs with the characteristic of being rotating, and / or that the oven is equipped with at least one of the hobs with the characteristic of being both rotating and vertically movable, and / or that the oven is equipped with hobs all of which are neither rotating nor © can be moved vertically.

DESCRIPTION OF AN EMBODIMENT OF THE INVENTION With reference to the attached figures, and in particular to figures from 1 to 5, the oven 30 is of the type with a single rotating plane adjustable in height, from a single lower fixed plane, a € ™ opening, or mouth, food inlet 31 and / or wood, a door and food inlet opening 32, while the rotating plate is indicated with 33.

The oven, which is closed at the top by a dome 34, resting on a support 35 which can be made in various ways, comprises a base 36 which constitutes the lower fixed cooking surface and which can be made of concrete, insulation, steel, mixed material or other, and which can also be used as a support base for cookware, food.

The furnace in question also comprises a wing 37 for the combustion of wood, a brazier 38 with possible ash discharge 39, and is made with a closing structure 40 of the front part of the dome where the openings are obtained. This structure 40 could be a continuation of the dome 34, constructed of the same material or of steel or other materials.

Figure 2 indicates in figure 2 the conveyor for the flue gas discharge, while 42 indicates the front panel of the oven, which has a metal and / or refractory structure and is complete with platform and upper hole for conveyor smoke.

The oven also comprises one or more pipes or one more through holes 43 for the introduction of gas / pellets.

Furthermore, the oven can comprise a plate 44 under the plate which prevents the upper cooking surface from cooling due to the steam from cooking the foods placed on the lower floors.

Figures 6 and 7 show an oven corresponding to the previous one, but this time with double rotating shelves 45 adjustable in height, a mouth 31 and a door 32. The remaining parts remain substantially unchanged with respect to the previous solution, and it is possible to note that the lower rotating surface actually replaces the lower supporting surface 36.

Also in this case there is the front panel of the oven 42, complete with floor and upper hole for the fumes conveyor, a pipe or through hole 43 for the introduction of gas / pellets, and a sheet 44 under the plate that prevents the hob to cool down due to the steam from cooking the foods on the lower floors.

Figures 8 and 9 show an oven according to a further embodiment of the invention, which has the characteristic of comprising double rotating shelves 45 adjustable in height and in this case in the front part there is only one mouth 31. in this version it is foreseen that the double rotating table can go up and down, making sure that the product can be introduced / withdrawn from the single inlet on the two levels.

Figures 11 and 12 show a version in which the oven is equipped with a double rotating top 45, possibly adjustable in height, and in this case the use of a door-shelf 46 is envisaged which also constitutes a shelf for the upper access mouth 31, made in such a way as to form a shelf which constitutes an access surface to the upper mouth and a closure for the underlying opening.

From the construction point of view, the mouth / hatch / floor 46 consists of a pair of floors arranged in a â € œLâ €, of which only the lower one is hinged to the edge of the access to the lower floor.

It should be noted that the door-floor 46 is made in such a way as to form a shelf for the upper access area 31, obtaining a type of construction that allows three important advantages to be achieved with the door open compared to the classic construction referred to in the simple door open 32:

1) less cold air enters and therefore the product cools less;

2) there is an improved view of the lower compartment; 3) there is easy access to the lower floor, to enter / withdraw product.

In the case of figures 13 and 14, a version is shown in which the rotating plane is single, similar to the plane 33 and the lower plane is fixed similarly to the plane 36, in figure 1, while in this case on the front it is a spout plus hatch-upper deck 46 was used.

Figures 15 and 16 illustrate a height-adjustable rotary oven 47 of the multi-level type, which envisages the use of an upper opening 31 for the food inlet, i.e. the opening found on all ovens from which food enters, and combustion fumes and cooking vapors come out.

The upper opening is affected by the presence of a hatch-platform 46, while the lower floors are affected by several food inlet doors 48, designed to allow access to the cooking areas under the main cooking plate.

This solution foresees that the upper mouth is equipped with a â € œnight closingâ € door, which can also be used for all the other models, and that it can be equipped with a door placed on the front before the smoke outlet hole.

It is also envisaged that the rotating planes 47 can be stopped independently of each other.

In figures 17 and 18 it can be seen that the lower rotating hob of the previous version is replaced by the fixed cooking plate 36, which constitutes a cooking hob in its own right and can be used in conjunction with the multiple rotating hob 47.

Finally, in figures 19 to 22 the multi-deck oven is only equipped with front doors 48, respectively in the versions without and with fixed lower cooking plate 36.

It is also foreseen the insertion in the furnace of electric heating and radiation elements, both main and auxiliary or also of gas burners, both main and auxiliary, all elements that determine an eventual increase of the temperature in correspondence of specific zones of the furnace.

All the possible combinations between doors, hobs can also be modular, such as: spout, spout with door-e, or all doors.

Or spout with door-e and floor door, combined with hobs such as: lift, rotation with lift, lift with rotating-i and stop-i, lift with rotation-i and stop-i, rotating-i, rotating-i and fixed and / or stationary, raised stationary and fixed, or other.

The invention has been previously described with reference to a preferential embodiment thereof. However, it is clear that the invention is susceptible to numerous variants that fall within its scope, within the framework of technical equivalences.
