Definitions

  • the invention relates to a method of restarting a new heating operation of a food at the end of cooking following a first heating operation, said food being placed inside an enclosure of a cooking appliance which is accessible by a door and which comprises at least one heating device with heating resistance, a microwave energy device, a circuit for supplying the heating device with heating resistance and with the microwave energy device, a control panel which comprises means for selecting at least predefined foods, means for entering information for a set duration T of a heating operation, means for displaying at least the set duration T and control means for triggering the progress of a heating operation; the supply circuit, the selection means, the information input means, the display means and the control means being connected to information processing means which, on the one hand, determine the different cooking phases of the heating operation to be applied to the food and, on the other hand, transmit messages, via the display means, to the user concerning said heating operation.
  • the information processing means when restarting a new heating operation on an already processed food, the information processing means take into account all of the phases of cooking the first heating operation to determine the new heating operation to be applied to the food.
  • this recovery procedure is unfortunately not satisfactory.
  • the food undergoes an energy treatment identical to the energy treatment of the first heating operation, the only difference being the duration of the new heating operation which has been modified.
  • Such an energy treatment generally involves, during the first cooking phase of the heating operation, at least one microwave energy applied with a very high power level corresponding for example to 90% of the maximum nominal power restored.
  • Said energy treatment applied once again to the food therefore causes the food to heat up too intensely, thereby modifying the nature of the food, namely obtaining either a food that is overcooked but not browned enough, or to a food that is too golden but not cooked enough.
  • the object of the invention is to remedy the aforementioned drawbacks and to implement a process for relaunching a new heating operation which ensures, in a simple and reliable manner, a new treatment of the food in order to improve the quality of the new heating operation.
  • the method for restarting a new heating operation for a food is characterized in that a message of said end of the first heating operation being transmitted to the user, the user selects a new setpoint duration tl by the information input means and triggers the control means connected to the information processing means which, on the one hand, automatically recall the first heating operation stored in said processing means and, d on the other hand, activate only the last cooking phase of said first heating operation.
  • the new heating operation of the already treated food is very much improved.
  • the selection of the last cooking phase of the first heating operation to be applied to the food during a new heating operation limits the power level of energy applied to said food, which ensures homogeneity of the temperature of the food by preventing excessive variations in the temperature of the food which are detrimental to a good heating operation on a food.
  • the method of relaunching a new heating operation for a food applied to an enclosure whose door has a opening and closing controlled by locking means connected to the information processing means is characterized in that after the end of the first heating operation, the information processing means test the locking means for the first time of the door to find out if an operation to open the said door has been undertaken, in the negative the procedure is continued, and if so the information processing means trigger a subroutine for continuing the new operation of heating.
  • the thermal variation due to the opening of the door is taken into account by the information processing means which determine the new heating operation to be applied to the food already treated.
  • the operating cycles of the power circuit of the heating resistance browning device and the microwave energy device are modified so that the food undergoes an optimal treatment meeting the wishes of the user.
  • the cooking appliance is a microwave oven which includes a cooking enclosure 1 in which food to be treated is placed and comprising at least one browning device with heating resistance 2 and one cooking device. generation of microwave energy 3.
  • the oven comprises a supply circuit 4, of known type, of the heating resistance browning device 2 and of the microwave energy generation device 3.
  • the cooking oven comprises a housing 5 containing the elements described in Figure 1, a door 6 mounted hinged on the front face of the housing 5 in order to open and close the enclosure of cooking 1 and a control panel 7 provided on the right side of the front face of the housing 5.
  • This control panel 7 comprises, among other things, selection means 8, for example a rotary button, making it possible to enter predefined foods, information input means 9 of a setpoint duration T of a heating operation, display means 10 of at least the setpoint duration T and control means 11 for triggering said heating operation on the food.
  • the set durations T of food heating operations are generally recorded in cookery books or in manuals delivered with said cooking ovens.
  • the supply circuit 4, the selection means 8, the information input means 9, the display means 10 and the control means 11 are connected to means of information processing 12.
  • Said information processing means 12 comprise, inter alia, calculation means 13 well known per se which determine the different cooking phases of a heating operation. Each of the cooking phases generally involves alternately, according to determined operating cycles, the heating resistor 2 and the microwave energy generation device 3 as a function of the information selected by the user.
  • the user At the end of a first heating operation on a food placed in the cooking chamber, the user looks at said food through the door closing the cooking chamber and, taking into account a first estimate, said user decides to start a new heating operation.
  • the method for restarting a new heating operation for a food is characterized in that a message of said end of the first heating operation being transmitted to the user, the user selects a new setpoint duration t1 by the information input means and triggers the control means connected to the information processing means which, on the one hand, automatically recall the first heating operation stored in said information processing means and, on the other hand, activate only the last cooking phase of said first heating operation.
  • the method for relaunching a new cooking operation for a food is applied in a cooking chamber, the door of which has an opening and a closing controlled by locking means connected to the means of information processing 12.
  • the information processing means test the door locking means a first time to find out whether an operation for opening said door has been undertaken, if not, the procedure is continued, and if so the information processing means trigger a subroutine before recalling the last heating operation and activating the last cooking phase of the new heating operation heater.
  • the information processing means 12 store the information on the opening of the door 6 for the determination of said new heating operation to be applied to the food and transmit to the user, thanks to the display means, a message of a request for the new setpoint duration t1, then the user having selected the new setpoint duration t1, the information processing means 12 test the locking means of a second time door 6 to find out whether an operation for closing the door has been undertaken, if not, the information processing means prevent the activation of the new heating operation and if so, after triggering of the control means, the information processing means automatically recall the last heating operation and, then, activate the last cooking phase of said last operation.
  • the information processing means 12 comprise timing means containing at least one timing of a duration tp , said duration tp having a value of the order of four minutes.
  • the information processing means at the end of the first heating operation, trigger the time delay tp during which, on the one hand, the user can select the setpoint duration t1 and trigger the control means and, on the other hand, the processing means test the locking means of the door 6, and, at the end of said time delay tp , if no actuation has been carried out on the input means information as well as on the control means, the information processing means continue the transmission of at least one message of the end of the first heating operation and trigger the passivity of the information input means.
  • the conditions for using the baking oven are improved. Indeed, beyond a certain duration, the temperatures of the food and of the cooking chamber have undergone great variations and, consequently, a restart of a heating operation on the food, without modification prior, would be harmful to obtain a good quality of the food.
  • the cooking chamber comprises a browning device with heating resistance, a heat device rotating, and a microwave energy generating device.
  • a browning device with heating resistance e.g., a heat device rotating, and a microwave energy generating device.
  • Such an oven is equipped with all the elements described in FIGS. 1, 2 and 3 and, in addition, it is equipped with a fan-assisted device supplied by the supply circuit 4.
  • the fan-assisted device comprises a convection resistor surrounding a fan supplied by the supply circuit 4 and intended to blow hot air inside the cooking chamber.
  • Such an oven also operates according to the method of the invention.
