Description

DESCRIPTION

Combustion oven for cooking.

OBJECT OF THE INVENTION 5

The present invention belongs to the sector of appliances intended for food preparation, and more specifically to the sector of food baking appliances. In particular, the object of the invention relates to a combustion oven for cooking that allows cooking simultaneously by radiation and convection. 10

BACKGROUND OF THE INVENTION

The ovens for cooking comprise a chamber, totally or partially closed, where the food is introduced, with a source of heat provided to said chamber for cooking or baking thereof. In the case of fuel furnaces, the heat source comprises a fuel such as coal or firewood arranged inside the chamber, leaving some vents for combustion to take place.

The chamber is made of refractory material and the food is placed in 20-baked containers, so that the heat input is mainly in the form of visible and non-visible radiation, and with little or no heat exchange due to the convection of gases and vapors, which implies, in addition to the non-thermal use of convection, that flavors of combustion are not provided, which implies a limitation compared to the use of other cooking appliances, such as barbecues. 25

Likewise, the current ovens for combustion cooking, due to their own design requirement in refractory material, have a difficult or impossible disassembly, and a high weight, so that their cleaning or transport present significant difficulties.

DESCRIPTION OF THE INVENTION

The present invention describes a combustion oven for radiation and convection cooking.

 35

This oven has advantages such as allowing an arrangement of food inside exposed to the convection movements of gases and vapors, which allows the thermal use of convection on the one hand and on the other the contribution of flavors of combustion, In addition to receiving heat contributions by radiation. Therefore it is a furnace operating by radiation and convection. 40

It also has advantages derived from its configuration, since not having an envelope with priority refractory properties, you can choose lighter materials, and even preferably structure the oven based on parts that can be assembled together, facilitating cleaning and transport. Four. Five

The oven comprises a chamber defined by an envelope in which there are arranged means for supporting hangers and / or cooking vessels for food and, at least, a container for the fuel that will constitute the heat source of the oven. It also has vents for the air to enter with the oxidizing oxygen, and 50 gas and vapors outlets from combustion and cooking.

The possibility of hanging food through hangers implies its exposure to internal flows of gases and vapors with contributions of flavor and heat by convection, flows

which are also propitiated by vents and outlets of gases and vapors, which will preferably have regulating elements, so that the combustion speed can always be regulated in a way that is more perfect and efficient, minimizing the emission of gases

PREFERRED EMBODIMENT OF THE INVENTION 25

Next, a detailed description of a preferred embodiment of the present invention is provided with the aid of the attached figures 1, 2, 3, 4 and 5 mentioned above.

 30

The combustion oven (1) for radiation and convection cooking generally comprises a chamber (2) where food is introduced (4), where the chamber (2) is defined by an envelope (5) inside which are located arranged: means of support (18) for suspending from them hangers (6) and / or cooking vessels (7) for food (4); and, at least, a fuel container (8) as a source of heat, and 35 providing the envelope (5) of vents (9, 28) for the combustion and outlets of gases and vapors (10) of combustion and cooking.

Preferably, the envelope (5) comprises a perimeter section (11), preferably cylindrical in this example of the invention, due to its greater ease of manufacture and uniform heat dispersion, with an upper cover (12) which, preferably, In the example shown in the figures, it is hinged to the perimeter section (11), and a lower section (13) removable by heat-resistant closures (31). At least, the perimeter section (11) and / or the lower sector (13) comprise a double wall (14, 15) as seen in Figures 3 and 4, with insulation (16) interposed for greater fuel efficiency and 45 to avoid burns. All parts of the enclosure (5): perimeter section (11) upper cover (12) and lower sector (13), are made of heat-resistant material, for example 316 stainless steel, which also provides better qualities against corrosion The dimensions of the oven (1) shown in the exemplary embodiment are by way of example: approximate height 94 cm and approximate diameter 59 cm. fifty

The upper cover (12) preferably comprises at least one glass window (17) resistant to the operating temperatures of the oven (1), through which the course of the cooking process can be controlled.

The support means (18) of the hangers (6) and / or cooking vessels (7) comprise at least one ring. Said support means (18), in particular said ring, are preferably located perimetrically, in a position that, in plan projection, is intermediate between the envelope (5) and the fuel container (8), as well as the support means (18) are at a level higher than that of the fuel container (8). 5

The hangers (6) comprise an upper hook (19) for hanging from the hoop and lower and / or intermediate skewer tips (20) for fixing the food (4). The intermediate position of the ring allows the hangers (6) to be placed without coming into contact with the inner wall (14) of the enclosure (5) or the fuel container (8). Furthermore, its annular configuration allows the cooking vessel (7) to be supported superiorly.

The fuel container (8) is in the form of a basket or cage as seen in Figure 4. It is open superiorly to place the fuel, for example firewood or coal, and the basket-shaped configuration allows access of the oxidizer for optimum 15 combustion

The oven (1) also includes handles (21, 22, 23), comprising: opening handles (21) of the upper cover (12), pushing handles (22) of the oven (1) and disassembly handles (23) of the envelope (5). The oven (1) also comprises wheels (24, 25) to facilitate 20 short displacements thereof, these wheels (24, 25) comprising fixed rear wheels (24) and directional front wheels (25).

The oven (1) may comprise, preferably in the lower sector (13), an inclined bottom (26) and an orifice (27) for the exit of fats (or juices, both generated during cooking) in the lower part of said inclined bottom (26), where a fat collection tray (3) is arranged, which can be removable. The way to materialize the inclined bottom (26) can be by design of the bottom itself or by wheel size (24, 25) and the position of its attachment points to the envelope (5). For example, the rear wheels (24) can be of different size, for example, larger than the front ones (25), to force the arrangement of an inclined bottom (26) oriented towards the hole (27).

The combination of the inclined bottom (2), together with the tray (3), and the preferred perimeter arrangement of the support means (18), cause the fats and juices generated during cooking to not precipitate within (or in contact with) the fuel container (8), thereby substantially reducing the generation of fumes and, therefore, of unpleasant odors.

The vents (9, 28) comprise a continuous perimeter take (9), five millimeters high in this example of the invention, materialized at the junction between the perimeter section 40 (11) and the lower sector (13) of the envelope (5) and at least one adjustable side outlet (28) arranged in the perimeter section (11), and comprising a gate (29) for regulating the passage of air with the oxidizer. The outlets of gases and vapors (10) comprise at least one spout arranged in the upper cover (12). Said spigot has a trapdoor, not shown, for regulating the output of said gases and / or vapors. Four. Five

Additionally, the oven (1) comprises a thermometer (30) of the internal temperature in the enclosure (5), which is arranged and visible from the outside.
