Definitions

  • the present invention relates to a method of cooking food in a domestic oven, if applicable appropriate in an industrial oven, in particular for to optimize the results of this cooking and, at the same time, to reduce energy to the bare minimum electric used.
  • baking ovens generally include the more generally, an internal muffle housed inside a external enclosure and in which food is placed to be cooked, this muffle being open towards the outside to allow access to its internal cavity and arrange in this food before it is closed by a pivoting door, mounted on the front of the enclosure external.
  • the oven has resistors inside the muffle electric heaters, mounted at the bottom and / or in its side walls and if necessary other resistors fixed to the ceiling of the muffle, generally providing a grill function for roasting Food.
  • Control and adjustment buttons usually arranged on the front face of the oven on a strip provided above of the pivoting door, allow to display the selected cooking parameters, which do not change during this cooking if the user does not modify them not himself, as he sees fit or based on data from cooking available.
  • the cooking temperature once displayed remains fixed, the heating resistors being kept energized until a sensor or analog, which continuously measures the temperature in the muffle, reaches the set point, in which case it provides a signal that cuts off the power until the temperature decreasing, the resistances are again powered and so on the temperature in the flask fluctuating around the displayed threshold.
  • a turbine or other similar ventilation may or may not be ordered to ensure a static or ventilated cooking as appropriate, evacuation gases and moisture produced in the muffle being provided by another fan which sucks the fumes and vapors from cooking, by permanently rejecting to the outside of the enclosure.
  • the present invention aims to improve very significantly the results of cooking food in the oven, making these results far less dependent on the precision of the programming carried out cooking time, while reducing the overall consumption of energy required to obtaining optimal cooking.
  • the process considered, for cooking of food placed inside an oven in particular a domestic oven heated with at least one electrical resistance, preferably by two or more resistors, sole and / or side wall, and / or grill, is characterized in that it consists in dividing the total cooking time of food prepared the interior of the oven muffle alternating several successive phases, within each of which is carried out, i.e. a temperature regulation by compared to a given threshold, i.e. a recovery of energy produced, in that, inside each of these successive phases, the oven operates in static or ventilated, while adjusting the humidity level in the oven muffle, by evacuation out of it.
  • the heating resistors are supplied independently and complementary to each other, but not simultaneously.
  • reference 1 designates a phase of the power supply and reference 2 the neutral of this food, oven or similar device comprising two switches 8 and 9, the closure of which performs electrical powering of resistors 4 and 5, respectively provided in the muffle ceiling of the oven to provide a grill function in particular, and in the side walls and / or the bottom of this muffle to normal cooking of the food placed in this muffle.
  • the switch 10 allows the energization of a fan 6 or a turbine, generally provided in the bottom of the muffle and the switch 11, putting under voltage of a second fan 7, generally designated under the term tangential, allowing to aspire in the muffles fumes or vapors from food to during their cooking, these fumes or vapors passing through the muffle's ceiling through a passage provided in this to be collected in a conduit arranged above of the muffle, in order to repress this smoke towards the outside of the oven enclosure, usually through an evacuation slot in the front of this enclosure, above or to the right of the door swivel which normally closes the latter.
  • Independent switches, respectively 8, 9, 10 and 11, according to the invention allow control individually or simultaneously the tensioning of elements, connecting them between phase 1 and neutral 2 of the food.
  • a programming device 12 enables these different switches according to a sequence performed in accordance with the process of the invention, ensuring a temperature regulation inside the muffle or energy recovery, this at the same time as the food is cooked in static mode, or in ventilated mode by authorizing rate control of humidity in the muffle, in particular by modifying the tangential fan speed.
  • the oven is equipped with two resistors, the electrical power of resistors 4 and 5 can be adjusted, especially to 2500 Watts for the grill and also 2500 Watts for the sole.
  • the resistor 4 is supplied for 20% of the cycle and the resistor 5 for 40%. In all cases, the two commands are at most complementary.
  • the cooking process is then carried out in the manner next.
  • preheating can be removed, the rise in temperature in the muffle being used to start cooking.
  • the first three phases are implemented in a way successive and repetitive as long as necessary to cooking, the last phase occurring only after a recovery.
  • the invention makes it possible to obtain significant gains in energy consumption, around 20% or even more, the better the better the oven isolated.
  • Cooking is less dependent on the total time used, the invention ensures a certain guarantee of result obtained, the recovery phase being particularly useful in the case of cooking meats where it advantageously replaces the period of usual rest, essential for obtaining quality optimal.
  • the baking of pastries is also optimized, the recovery phase making it possible to obtain more softness than with conventional cooking.
  • the system can be coupled with a programmer, to obtain semi-automatic cooking.
  • the sequences of phases then depend on the type of cooking selected, and the duration of each phase of the total programmed time.
  • the invention is not limited not to the embodiment more specifically described above with reference to the accompanying drawings; she in on the contrary embraces all variants.
  • the method can be implemented with a number of resistors greater than two, alternating controls of these resistors to reduce the power installed from the device.
