  • control method further comprises a step of starting the control means associated with the detected focus.
  • the automatic detection of the hearth covered by a container is also translated by the activation of the control means associated with this focus, allowing the user to adjust the power directly at the control means.
  • the identification step can be implemented by lighting a diode disposed near the control means associated with the detected focus or by the illumination of display means integrated with the control means associated with the detected focus.
  • the present invention also relates to a hob comprising at least two cooking hobs associated with control means, means for detecting a hearth covered by a receptacle, and means for identification by a signal visual control means associated with the detected focus.
  • This hob has characteristics and advantages similar to those described above with reference to the control method according to the invention.
  • the hob includes four firing hobs F.
  • These cooking hobs are in this embodiment consist of one or more inductors for heating a container by the principle of induction.
  • each focus F is associated with a power control means 11 whose setting is accessible to the user by means of control keys associated with each focus F.
  • tactile control means accessible directly at the level of the plane of the hob 10.
  • control means 11 allow the ignition or extinction of each home and the power control, for example by an index between 1 and 12.
  • control means 11 cooperate with a global control system 20 as illustrated in FIG. figure 2 which adjusts the power supply of each household according to the power demand demanded by the user.
  • the hob 10 further comprises means for inputting a signal into the overall control system 20 to indicate the presence of a container on one of the hobs of the hob.
  • This input means consists of an acquisition key 12 disposed on the cooking plane 10.
  • a touch control input key 12 also provided at the hob 10 of the table, allowing the user to indicate by touching this input key 12 the presence of a container R on one of the hobs of the table.
  • the hob further includes means for detecting a focus F covered by the container R.
  • each cooking chamber F is associated with detection means for detecting the presence of a container above the fireplace.
  • these detection means may be inductive type means for detecting the presence of a container when the average current measured at the terminals of these inductors varies.
  • the cooking hobs are themselves constituted by inductors, it is particularly advantageous to provide that these inductors are also means for detecting the presence of a container R on a focus F.
  • thermal type detection means could be used, and for example thermal type detection means.
  • the hob includes identification means 13 by a visual signal of the detected focus F.
  • the identification means consist of an LED 13 (Electro Luminescent Diode) disposed near the control means 11.
  • This LED 13 makes it possible to visually indicate to the user the control means 11 associated with the hearth on which a container R has been placed.
  • control means associated with each cooking zone can incorporate display means that make it possible, for example, to indicate the active or inactive state of these control means or to indicate, for example, example by means of a number, the power level programmed by the user.
  • the identification step can be implemented by illuminating these display means integrated with the control means.
  • the identification by a visual signal of the detected focus is performed directly at the control means respectively associated with each focus of the hob.
  • any control key 11 since it is in an inactive state, could constitute a key for acquiring an input signal and thus allow the transmission of a signal indicating the presence of a signal. new container and provide a means of input of a signal adapted to indicate the presence of a container for any of the homes.
  • the overall control system 20 of the hob implements the detection of a new container and indicates visually the control keys 11 actually associated with the fireplace used.
  • FIG. figure 2 The control system associated with such a hob is illustrated in FIG. figure 2 and allows the implementation of the following control method.
  • An input signal acquired by the acquisition key 12 is transmitted to the global control system 20 which, in response, controls the implementation of a step of detecting a focus covered by the container.
  • a detection system 21 is associated with each focal point F of the table. Depending on the signal measured by this detection system, for example the value of a current at the terminals of an inductor, which is modified as a function of the load ( container) placed opposite this inductor, the hearth F covered with a new container is detected.
  • the detection of a container on a fireplace is implemented only on the detection systems 21 for which the associated home is not already used and power controlled.
  • the detection is thus implemented only on inactive cooking hobs.
  • the global control system 20 identifies the focus covered by the container and generates in this embodiment an ignition control of a diode 13 associated with the control means 11 dedicated to this detected focus.
  • the user can control and control the heating power of the hearth thus detected by the control means 11 thus marked on the cooking plane.
  • the global control system 20 is adapted to start the control means 11 associated with the detected focus F.
  • the user can directly locate the control means 11 associated with the chosen hearth and controlling, via these control means, the power allocated to the hearth, without first having to make these control means 11 operational.
  • these power delivery means 22 may consist of a power generator when each cooking hearth is of the inductive type.
  • control keys 14 may be associated with the global control system 20, and for example a timer 14 associated with each control means 11 for programming for a given home a running time or a start-up delayed.
  • the control method of the invention thus makes it possible to control a hob by means of an automatic detection device for a container that intuitively enables the user to control the power associated with the chosen fireplace.
  • the step of automatic detection of a container being implemented preferably on an inactive focus, it can detect a newly installed container by the user on the hob.
  • control method according to the invention will perform dual detection and visually signal the two foci detected.
  • Delaying means may also be integrated into the hob so as to automatically control the extinction of the visual signal when no power indication has been entered by the user at the identified control means.
  • this delay period may be of the order of 30 seconds.
  • a container can remain on a fire that is off after cooking.
  • the container detection means do not take into account such a container.
  • storage means are integrated in the hob and can store in memory for a given time an active state of a home, even after extinction thereof.
  • the detection means 21 detect at the both the new container and the container used previously.
  • the global control system 20 is then adapted to identify by a visual signal only the focus for which an active state is not stored.
  • This active state of a focus can be stored in memory for a certain duration, for example equal to one hour.
  • a memory associated with the global control system 20 is adapted to store different states associated with each focus of the hob.
  • Example 1 a new container placed on an inactive fireplace, one or more other active homes possibly:
  • Example 2 two new containers placed on inactive foci, one or more other active foci possibly:
  • Example 3 a new container placed on an inactive hearth, a second container present on a second fireplace stopped after cooking, one or more other active homes possibly:
  • control means associated with the hearths can be carried out first of all for the hearths on which the receptacle has been most recently laid, then on the hearths of the most recently extinguished to the oldest extinguished or reciprocally the older extinct at most recently extinguished.
  • Example 4 a new container placed on an inactive hearth, a second container and a third container disposed respectively on a second focus and a third focus arrested after cooking, one or more other active homes possibly:
  • the cooking stoves may not be made of inductors but for example radiant or halogen foci.
  • Detection means of a container independent of the furnace heating means are then integrated into each home.
  • These detection means can be as previously means of the inductive or thermal type.
  • the identification by a visual signal of the control means associated with the detected focus is performed near the control means on the hob.
  • the invention could also be implemented in a hob comprising control means common to all cooking hobs and means for selecting the hearth which must be actuated previously by the user to then power control the selected fireplace .
  • the identification by a visual signal of the control means could then be implemented at the means of selection of the focus, for example by the illumination of a diode disposed near the various selection keys respectively associated with the cooking stoves , or by the lighting of these selection keys if they include integrated lighting means.
  • the identification by a visual signal of the selection of a focus automatically allows to associate the control means common to the detected focus.
