Definitions

  • the present invention relates to a cooking appliance comprising a cooking cavity comprising a device for browning food with electrical resistance placed inside said cavity and a device for generating microwave energy placed outside of the cavity and capable of supplying said cavity with microwave energy, a supply circuit for supplying the browning device and / or the microwave energy generation device, selection means making it possible to trigger a sequence of heating, said heating sequence involving the browning device and / or the microwave energy generation device, entering the nature and the weight of the food, and control means which activate the supply circuit electrical as a function of the information from the selection means, said control means comprising a storage memory receiving the information from the mo selection yen and a microprocessor supplying signals applied to the supply circuit according to the information contained in said storage memory.
  • a user when a food is placed inside the cooking cavity, a user begins a heating sequence by selecting a determined heating function, a family of foods and its weight. and, then by pressing a button, it initiates said heating sequence.
  • the control means determine the heating sequence (browning device and / or microwave energy generation device) thus calculating the heating time of the cooking appliance so that the food undergoes the best possible treatment.
  • a food family generally includes several types of food.
  • the VOLAILLES family includes, for example, chickens, ducks, guinea fowl, quail, pheasants ...
  • the control means after analysis of the selected family, determines a heating sequence which is adapted to the average population of the family. foods and not to each type of food. Furthermore, for foods of low weight and whose heating sequence involves at least the browning device, the heating sequence calculated by the control means makes it possible to obtain either a food that is too golden but not cooked enough, or a food overcooked but not browned enough. The calculated heating sequence therefore never exactly meets the wishes of the user, namely obtaining a sufficiently cooked and golden food whatever the type and weight of the food to be treated.
  • the object of the invention is to remedy the aforementioned drawbacks by using a cooking appliance which, taking into account the type and weight of the food to be treated, determines the optimal heating sequence selected by the user to obtain a sufficiently cooked and golden food.
  • the storage memory contains a table of values of coefficients a i for each value i and a threshold value P0 corresponding to a determined value of abscissa of the optimization curves below which , for a heating sequence involving at least the browning device, the control means calculating the heating time take into account a weighting coefficient whose value is determined by the product of the coefficient a i by the value P0.
  • the plurality of selectable codes favor the refinement of the heating optimization curves, thus making it possible to calculate, with greater precision, the heating time of the cooking appliance.
  • An electrical supply circuit not shown and capable of supplying the browning device 3 and / or the microwave energy generation device 4.
  • the cooking cavity 2 is delimited by a door 5 shown in dotted lines and placed on the front face 6 of the cooking appliance.
  • This partially shown front face 6 includes selection means not shown which make it possible to trigger a heating sequence to be carried out on a food 7, to capture the nature 7 as well as the weight of the food 7.
  • the cooking appliance 1 comprises control means, not shown, which comprise, on the one hand, a storage memory receiving information from the selection means and, on the other hand, a microprocessor supplying signals applied to the circuit according to the information contained in the storage memory.
  • an optimization curve 8 of a heating sequence of a food involving only the microwave energy generation device represents the heating time T defined for example as ordered as a function of the weight P food defined for example as abscissa.
  • T KP
  • K represents the slope of the curve.
  • control means comprising first calculation means determine a slope value K i of the optimization curve of the heating sequence to be calculated by the relation:
  • the storage memory contains a table of values of coefficients a i for each value i and a threshold value P0 corresponding to a determined value of abscissa of the optimization curves below which, for a heating sequence involving at least the browning device, the control means calculating the heating time take into account a weighting coefficient whose value is determined by the product of the coefficient a i by the value P0.
  • the abscissa P0 corresponds to the inflection point of the optimization curves for cooking of different types of food, the section of curve of coordinate less than P0 corresponding to a heating sequence with at least the gilding device.
  • the weight threshold P0 is substantially equal to 400 g.
  • Said control means thus comprise second calculation means for, on the one hand, comparing the weight of the selected food with the weight threshold P0 and, on the other hand, determine, as a function of the result of the comparison of the weights, the heating time of the cooking appliance.
  • the storage memory contains, for each heating sequence, a maximum heating time not to be exceeded and the control means include third means of calculation which, on the one hand, compares the heating time calculated by the second calculation means with the maximum heating time for a determined heating sequence and, on the other hand, as a function of the result from the third calculation means, trigger either an error message if the calculated time is greater than the maximum time, or the heating sequence determined by the control means.
  • Figure 3 a flowchart corresponding to the method of controlling the cooking of a food.
  • a heating sequence After the user has placed a food to be treated in the cooking cavity, the user selects a heating sequence, the weight of the food and a code number ⁇ i corresponding to the particular food to be treated. Then he presses a start button to start the operation of the cooking appliance.
  • the information entered by the user is transmitted to the control means which, taking into account the information stored in the storage memory, determine the slope value K i of the sequence optimization curve selected heating system.
  • the control means carry out a test on the weight of the food to be treated with respect to the weight threshold P0.
  • control means first compare the calculated heating time corresponding to an optimal heating time value with the maximum heating time contained in the storage memory and then trigger or not the activation of the circuit. powering the browning device and / or the microwave energy generation device.
  • the method according to the invention offers the advantage of obtaining an automatic cooking of the food thanks to the precision concerning the nature of the food.
  • the optimization curve is refined by approaching an ideal optimization curve, said curve obtained making it possible to meet the expectations of each user.
