Definitions

  • the present invention relates to an electrically powered cooking chamber, comprising a muffle provided with at least one ceiling heating element, at least one hearth heating element, an air circulation turbine placed in the rear wall of the muffle , a diffuser plate directing the air forced into the muffle, an electrical switching device comprising contacts for the selective energization of the heating elements of. ceiling, sole and turbine.
  • This electrically powered cooking chamber therefore comprises at least one ceiling heating element, at least one hearth heating element, and an air circulation turbine, but it can also additionally comprise a heating element ventilated by the air circulation of the turbine to form a modern cooking chamber equipped with all these heating elements.
  • the switching device of this cooking enclosure allows the user to program several positions each adapted to a particular cooking, such as, for example, a position called “conventional” or another called “hot air”.
  • this "pulsed grill" position does not allow simultaneous cooking of several dishes, identical or different.
  • the present invention therefore aims to allow these simultaneous cooking and to simplify manufacturing because it is possible, from a conventional cooking enclosure, simply add a fan, a diffuser and a switch to control the fan.
  • the present invention relates to an electrically powered cooking chamber, comprising a muffle provided with at least one ceiling heating element, at least one hearth heating element, an air circulation turbine placed in the rear wall. of the muffle, a diffuser plate directing the air forced into the muffle, a heating element ventilated by the turbine, an electrical switching device comprising contacts for the selective energization of the heating elements and the turbine, characterized in that that the switching device comprises a position according to which at least one ceiling heating element, at least one floor heating element and the air circulation turbine, are energized in parallel with one another, the ventilated heating element not energized.
  • This switching mode makes it possible to obtain a homogeneous distribution of the heat in the oven, which, in the case of the simultaneous cooking of several dishes, is an important element to prevent that one does not absorb all or part of the energy needed by others. Heat arrives from the top and bottom and is then distributed evenly by the turbine.
  • the switching device has a position according to which these two floor heating elements are connected in parallel, at least one ceiling heating element and the circulation circulation turbine. air being connected in parallel to the assembly.
  • the switching device has a position in which these two heating elements ceiling heaters are connected in series, at least one floor heating element and the air circulation turbine being connected in parallel to the assembly.
  • a variant is provided in which the ceiling heating elements are placed in parallel with one another and with the turbine and the floor heating element.
  • the muffle 1 delimits by its upper wall 2, its lower wall 3, its rear wall 4 and its two side walls 5, 6, a cooking cavity 7, this muffle of course being closed on its front part by a door (not shown), during cooking.
  • a turbine 8 driven by an electric motor 9 and separated from the cooking cavity 7 by a diffuser plate 11 pierced in its central part with suction orifices 12.
  • the air driven by the turbine is discharged into the cooking cavity along the side walls 5, 6 of the muffle.
  • Sole heating elements 20, 21 are arranged below the bottom wall 3 of the muffle 1. These sole heating elements can, of course, be arranged above the wall bottom of the muffle, i.e. in the muffle.
  • the floor heating elements are two in number, a peripheral element 20 and a central element 21, which make it possible to obtain an optimal and homogeneous distribution of the temperature as required.
  • At least one ceiling heating element 30, 31 is provided near the upper wall 2 of the muffle 1.
  • two ceiling heating elements are provided, a roof heating element 30 and a grill heating element 31.
  • the enclosure may also include a heating element ventilated 10 by the circulation of air from the turbine 8, used in particular in another position of the switch, for example in the "circulating heat" position.
  • FIG. 3 shows a simplified diagram representing only the elements necessary for the implementation of the invention, and in the case of a cooking enclosure comprising a ventilated heating element, the latter would obviously not be energized.
  • the various heating and ventilation elements used in this particular position are associated with switching means comprising in the example seven contacts A to G of the same switch operated by a single control button (not shown), a thermostatic contact 1 manually adjustable, and an independently operable H contact.
  • this contact H can be integrated into the seven-contact switch A to G.
  • terminals 40, 41 representing a voltage source such as the 220V sector for example.
  • the turbine motor 8 is connected in series with the contact A and in parallel with the various floor heating elements 20, 21 and of the ceiling 30, 31.
  • the two sole elements are energized simultaneously, they are preferably so in parallel with one another.
  • the cooking chamber can for example be an oven or a cooker with manual, catalytic or pyrolytic cleaning, and include all the conventional accessories of a conventional cooking chamber and for example a temperature probe, muffle lighting and a smoke catalyst.
