Definitions
- the present invention relates to ovens for cooking food. 'More particularly, the invention relates to an oven for cooking food comprising:
- this enclosure intended to receive the food to be heated and to contain a cooking atmosphere, this enclosure comprising two horizontal walls, respectively forming a sole and a vault, connected by at least two vertical side walls, this enclosure being closed by at least one also vertical door,
- a heating device placed inside the enclosure
- a turbine also arranged inside the enclosure, comprising at least one blade rotating around a central space, on a circular trajectory centered on a axis of rotation, to stir the cooking atmosphere heated by the heating device.
- Furnaces of this type are already known in which, for example, the food to be cooked is distributed over trays arranged on several levels. In these ovens, the food must cook at the same speed and with the same degree of cooking on all levels. The homogeneity of the heat distribution in these ovens is therefore particularly important.
- the object of the present invention is in particular to improve the uniformity of the heat distribution in the enclosure of ovens of this type.
- an oven which, in addition to the characteristics already mentioned, is characterized in that the heating device is arranged opposite the central space located inside the circular path.
- the heat produced by the heating device is sucked in by the turbine and then distributed around it uniformly. This contributes to considerably improving the distribution of heat throughout the entire volume of the enclosure.
- the axis of rotation is horizontal; thus, for example, the turbine is rotatably mounted on one of the vertical walls of the enclosure;
- the heating device is an electrical resistance or a combustible gas burner;
- the burner comprises a bowl and a plate, the bowl being connected to a fuel gas supply duct and being closed, on its face oriented towards the wall of the enclosure on which the turbine is mounted, by the plate, and this plate being provided with orifices for the passage of combustible gas; the burner is therefore oriented towards the wall of the enclosure on which the turbine is mounted; thus, if the burner and the turbine are only protected by a simple grid, the heat generated by the burner is not directly emitted towards the food to be heated and / or cooked;
- the orifices of the burner plate are adapted so that the flames generated by the combustion of the combustible gas are distributed over 3 ⁇ 0 ° relative to the axis of rotation; - electrical supply wires from a burner gas ignition device pass through the supply duct; this takes advantage of the relatively low temperature prevailing in the supply duct, thanks to its sweeping by the combustion gas, to protect the electrical supply wires;
- the plate is provided with an ignition electrode and a flame control device, for example by ionization;
- FIG. 2 is a schematic section of the oven shown in Figure 1, in a vertical plane perpendicular to the bottom wall, cutting the bottom wall and the burner substantially through the middle;
- FIG. 3 is a schematic section, in a plane similar to that of Figure 2, of the oven burner shown in Figures 1 and 2;
- FIG. 4 shows schematically, top view, the burner plate shown in Figures 2 and 3;
- FIG. 5 shows schematically, front view, a variant of the protective grid which can, according to certain variants of the oven according to the invention, protect its burner and its fan;
- FIG. 6 shows schematically in section, the protective grid shown in Figure 5.
- the oven 1 comprises an enclosure 2 (or muffle) contained in a formwork 3.
- This formwork 3 comprises means for regulating the temperature 4 in the enclosure 2, as well as a door 5 intended for introduction into enclosure 2.
- the enclosure 2 has a substantially parallelepiped shape with a front face 6, open or closed by the door 5, a bottom wall 7 opposite the front face 6, two side walls 8 vertical, between the front face 6 and the wall of bottom 7, as well as a sole 9 and a vault 10 forming two horizontal walls.
- the oven 1 according to the invention also includes a heating device 11, a turbine 12, a protective grid 13 and slides 14.
- the turbine 12 is mounted on the bottom wall 7.
- the heating device 11 is arranged inside the enclosure 2, facing the turbine 12.
- it is a combustion gas burner. It is supplied with combustion gas by a pipe 15. This burner is ignited by an electrode 16 electrically supplied by a wire 17 arriving in the burner by the pipe 15. This burner will be described in more detail below in relation to the Figures 3 and 4.
- This burner advantageously comprises a flame control device 16a, for example by ionization, connected to a control box (not shown) by a wire 17a.
- the combustion gas is advantageously an air / gas mixture arriving at the burner at slight overpressure.
- the turbine 12 consists of a disc 18 centered on an axis of rotation 19. At the periphery of this disc 18, the turbine 12 comprises a plurality of blades 20 regularly angularly distributed around the axis of rotation 19. These blades 20 are for example made up of plane rectangular strips extending in a plane substantially perpendicular to the disc 18 and passing through the axis of rotation 19. During their rotation, they travel a circular trajectory centered on the axis of rotation 19 and delimit a central space 21.
- the turbine 12 is driven in rotation, around the axis of rotation 19, by a motor 22, by electrical example. It distributes the heat energy in enclosure 2.
- the protective grid 13 extends in a vertical plane opposite the disc 18, in front of the burner 11 and the turbine 12, relative to the space 23 intended to receive the food to be heated and situated between this burner 11 and the door 5 .
- the slides 14, ten in number, are arranged substantially horizontally on the • side walls 8.
- Each side wall 8 has a slide 14 of each pair. These slides 14 make it possible to maintain trays on which the food to be heated and / or cooked is arranged.
- the burner 11 is arranged opposite the central space 21.
- part of this burner 11 penetrates into this central space 21.
- the enclosure 2 comprises an orifice 31 for discharging the gases contained in the enclosure 2.
- the burner 11 comprises a bowl 24 and a plate 25.
- this bowl 24 and this plate 25 are made of brass.
- the bowl 24 is connected to the supply duct 15 and is closed by the plate 25, on the side of the burner 11 oriented towards the bottom wall 7 of the enclosure 2.
- the plate 25 is has the form of a ring with a central opening 26 which extends, perpendicular to the plate 25, to the bottom of the bowl 24 by a tube 27.
- the plate 25 is substantially 15 mm thick.
- the zone of this ring located between the central opening 26 and its periphery is pierced with orifices 28 regularly distributed over eight concentric circles AH. These concentric circles are respectively 66 mm, 74 mm, 82 mm, 90 mm, 98 mm, 106 mm, 114 mm and 122 mm in diameter. Found on these circles respectively 32, 32, 40, 48, 48, 64, 64 and 64 orifices 28. Each orifice 28 has a diameter substantially equal to 2.4 mm.
- the plate 25 has a recess 29 having a depth substantially equal to 3 mm.
- the orifices 28 are not directly flush with the surface of the plate 25 and are partly protected from the turbulence generated by the turbine 12.
- the geometry of the orifices 28 and the recess 29 is adapted so that the flames generated by the combustion of the gases extend, under the effect of the turbine 12, radially with respect to the central opening 26, over 360 °.
- the plate 25 also has two passages 30 for the ignition electrode 16 and the flame control device 16a.
- the oven according to the invention can be the subject of numerous variants without departing from the scope of the invention.
- the enclosure 2 has a front face and a rear face, open or closed, each by a door.
- a turbine 12 is mounted, for example, on at least one side wall 8 and the heating device 11 is placed opposite each turbine 12.
- the oven according to the invention comprises a protective grid 13 as shown in Figures 5 and 6.
- This protective grid 13 is not limited, contrary to what has been described above , to a surface corresponding to that facing the turbine 12.
- the protective grid 13 is supported by a metal frame 40.
- This frame 40 extends over most of the opening of the internal cavity of the enclosure 2, in a plane parallel to the bottom wall 7.
- the dimensions of the frame 40 are substantially equal to or greater than those of the turbine. 12.
- the frame 41 can play a deflecting role.
- the frame 40 is, for example, maintained in the enclosure 2, thanks to. legs 41, on the floor 9 and the roof 10.
- the protective grid 13 and the frame 40 are easily removable so as to be cleaned independently of the oven 1.
