Definitions

  • the present invention relates to a cooking oven, in particular for domestic use, of the type comprising a cooking enclosure having, on one of its side walls, a double wall delimiting a compartment inside which is mounted a circulation fan d air, the internal wall of the double wall having, at its lower part, at least one so-called air suction opening opposite which the fan is arranged and, at its upper part, at least one so-called discharge opening of air, as well as an electric heating resistance of the grill arranged in the enclosure, outside the compartment and facing the air discharge opening, and acting both as a broiler resistance when the oven is used in grill cooking mode for which the fan is inactive and heating resistance ventilated by the air circulation created by the fan when the oven is used in cooking mode n by forced convection.
  • the invention proposes to solve this simple radiation problem of the grill in a simple and effective manner when it is used in forced convection cooking mode.
  • the cooking oven according to the invention of the type recalled above and characterized in that the grill resistance is subject to means for reducing the power which it absorbs only when the oven is used in forced convection cooking mode.
  • the temperature of the grill resistance is thus lower in cooking mode by forced convection than it is in cooking mode by grill.
  • the power reduction means consist of a simple additional electrical heating resistor connected in series with the grill resistor by means of an electrical switching device and having an absorbed power notably lower than that of grill resistance.
  • this additional resistance is placed in the enclosure, outside the compartment, and situated at the same level as the grill resistance. This arrangement increases the exchange surface between the grill resistance and the ventilated air, which reduces the temperature rise time of the oven.
  • the cooking oven in particular for domestic use, comprises a cooking enclosure or cavity 1 of generally parallelepiped shape which, of course, is closed by a door (not shown) during the cooking.
  • the enclosure 1 has, at its rear part, a double rear wall 2a and 2b delimiting a closed compartment 3 of rectangular cross section. Inside this compartment 3, in the vicinity of the floor 2c of the enclosure, is mounted an air circulation fan 4 driven in rotation by an electric motor 5 and placed in look of air suction openings 6 formed in the internal wall 2b of the enclosure. This same internal wall 2b of the enclosure is also provided with air delivery openings 7 located near the vault 2d of the enclosure.
  • the compartment 3 of the cooking enclosure 1 also contains a thermostatic device (not shown) known per se for controlling the interior temperature of the enclosure.
  • a grill heating element 8 is mounted at the top of the enclosure 1 parallel to its vault 2d, outside of its compartment 3, that is to say in the cooking chamber 9 proper, and opposite air discharge openings 7.
  • This grill resistance 8 is intended to fulfill a double function, namely that of the grill itself when the oven is used in grill cooking mode for which the fan is not in operation, and that of air heating. ventilated under the action of the fan 4 to ensure an even distribution of heat throughout the volume of the cooking chamber 9 when the oven is used in forced convection cooking mode.
  • an additional electric heating resistor 10 intended to be used only when the oven operates by forced convection, is connected in series with the grill resistor 8 (Figure 3) while being disposed in the enclosure outside. from its compartment 3 and at the same level as the grill element 8 ( Figure 2).
  • This additional resistance 10 is chosen so as to develop, in forced convection cooking mode, a power significantly lower than that of the grill resistance 8.
  • the additional resistor 10 develops a power of the order of 100 watts.
  • the additional resistance 10 can be housed inside the compartment 3 so as to be used only as a contribution in temperature and not as a contribution in temperature and radiation.
  • connection mode of the two electrical resistors 8 and 10 results from the simplified diagram of FIG. 3, in which we see that these two resistors are each associated with a switch contact 11, respectively 12, of a device electrical switching 13; the fan 4 is connected in parallel to the additional resistor 10.
  • the selective opening or closing of the contacts 11 and 12 is effected by a single control button (not illustrated) located on the control panel of the oven.
  • the entire assembly is intended to be connected via its terminals 14 and 15 to a voltage source, for example 230 volts.
  • the contacts 11 and 12 are respectively in the closed and open position, so that only the grill element 8 is energized and therefore fulfills its conventional broiler function.
  • the contacts 11 and 12 are respectively in the open and closed position, so that the two resistors in series 8 and 10, as well as the fan 4, are energized.
  • the air from the cooking chamber 9 is sucked in by the fan 4, inside the compartment 3 of the enclosure via the openings 6, and is then projected onto the two resistors in series 8 and 10 via the openings 7 (see arrows F in FIG. 2) so as to heat the air in the cooking chamber 9.
  • the additional resistance 10 therefore reduces the power absorbed by the grill element 8, so that the latter radiates more weakly.
  • baking oven according to the invention described above can also use a additional heating by microwave, without departing from the scope of the invention.
