Definitions

  • the invention relates to a cooking appliance.
  • a cooking chamber comprising at least one heating resistance browning device and a microwave energy generation device a feed circuit of the gilding device to heating element and microwave energy device and a control panel which includes means selection to enter food families predefined means for entering information of a setpoint duration T of a family cooking phase food, means for displaying the time of at least the setpoint duration T, and control means for trigger the progress of said cooking phase, the means of selection, means of information entry, the display means and the control means being linked to information processing means which include, among other things, storage means at least the setpoint duration T and means on the one hand, for canceling said setpoint duration T and, on the other hand, the circuit supply Power.
  • the tables of control of said ovens have keys specialized allowing the cancellation of a phase of cooking during its progress. These keys increase the complexity, on the one hand, of the control panels and, on the other hand, the construction of said ovens.
  • the object of the invention is to remedy the aforementioned drawbacks and allow cancellation simple and quick cooking phase during unwinding.
  • the processing means include means for switching between the cancellation means and the selection means for that upon actuation of the selection means during the course of a cooking phase, the means selection activates the cancellation means.
  • the cooking appliance according to the invention reduces the number of parts and therefore the size of the oven control panel. So time and cost of manufacturing such an oven are considerably reduced.
  • the use of a same key to perform two different functions we improves the user-friendliness of such an oven.
  • the operational safety of these furnaces by prohibiting the operation of the initial cooking while the user has changed the means of selection either by mistake or voluntarily.
  • the cooking is an oven that includes a cooking chamber 2 in which food to be processed is placed, and comprising at least one resistance browning device heater 1 and an energy generation device microwave 3.
  • the oven has a power circuit 4, of known type, of the resistance gilding device heater and power generation device microwave.
  • the cooking includes a box 5 containing the elements described in Figure 1, a door 6 hinged mounted on the front face of the case 5 in order to open and close the cooking chamber 2 and a control panel 7 provided on the right side of the front face of the case 5.
  • the control panel 7 comprises, inter alia, means selection 8, to enter families predefined foods, means of entry information 9 of a setpoint duration T of a phase of cooking, time display means 10 and means 11 to trigger the progress of a phase of a family of food.
  • Ways time display 10 of known type ensure, between others, on the one hand, the visualization of the duration of time setpoint T selected as well as the countdown of said time selected during a phase of cooking and, on the other hand, the indication of the time when the oven is in rest mode.
  • Food families that can be chosen by the selection means 8 bring together a first family of foods containing whole poultry 12, whole fish 13 and 14 white meats, as well as a second family of food containing ready meals 15, meats reds 16 and pizzas 17.
  • the setpoint times T of food cooking phases are entered usually in cookbook or in manuals supplied with said ovens.
  • processing means information 20 include, among other things, means memorizing 21 of at least the setpoint duration T, means 22 of cancellation, on the one hand, of said duration of setpoint T and, on the other hand, of the circuit supply supply 4, and well known calculation means 23 which determine the operating cycles of the heating resistance browning device 1 and device 3 for generating microwave energy in according to the information selected by the user.
  • the means of treatment information 20 include switching means 18 between the cancellation means 22 and the means of selection 8 so that, when the means are actuated of selection during the course of a phase of cooking, the switching means 18 activate the means cancellation.
  • the selection means 8 comprise for example a rotary knob at a determined position in front of each of the selectable food families.
  • the information processing means 20 comprise timing means 24 intended to be activated by the switching means 18 when the selection means 8 are actuated during the course of a cooking phase and triggering a suspension phase during which the user can trigger a new cooking phase.
  • the user can, firstly, reselect the setpoint time T and / or the food family and, secondly, trigger a new cooking phase by actuating the means of command 11.
  • the duration D of the suspension phase is chosen by the manufacturer and has a value of the order of four minutes.
  • the information processing means 20 transmit a signal to the time display means 10 intended to indicate to the user that the oven is in idle mode.
  • the time display means 10 indicates the time to indicate the rest mode of the cooking appliance.
  • the operating method of the cooking according to the invention is therefore easy and effective.
  • the user places a food in the enclosure of cooking 2 and closes the door of said enclosure 2.
  • the user selects the setpoint duration T, the family food placed in the cooking chamber 2 and actuates the control means 11 to trigger the progress of a cooking phase. If the user realizes that he has to make an error in the cooking appliance programming, it performs a actuation of the selection means 8 and reprogram the cooking appliance by manipulating either the means of selection 8, i.e. the information input means 9. Then it activates the control means 11 for start the new cooking phase.
  • the cooking chamber includes a device heating resistance gilding, a device with fan, and a generating device of microwave energy.
  • a device heating resistance gilding a device with fan
  • a generating device of microwave energy a device heating resistance gilding
  • Such an oven is equipped with all elements described in Figures 1, 2 and 3 and in addition, it is equipped with a fan-assisted powered device by the supply circuit 4.
  • the heat device rotating includes a convection resistor surrounding a fan powered by the power circuit 4 and intended to blow hot air inside the cooking chamber.
  • Such an oven also works according to the invention.
  • the information processing means 20 activate the switching means 18 which cuts power supply to the resistance browning device heater 1, of the energy generation device microwave 3 and fan heater.
