Definitions

  • the present invention relates to a device for determining the location of cooking utensils on a cooking hob comprising a plurality of heating elements distributed in a matrix pattern below a heat-resistant surface on which the cooking utensil can be placed in a random manner, each heating element being capable of working also as a magnetic field transmitter, the device comprising loops placed substantially around portions of the matrix of heating elements and working as magnetic field receivers.
  • a device of this type is disclosed in EP-A-1206164 .
  • the present invention relates to an improvement of the receiving coil antennae or loops used to pick up the electromagnetic field generated by the heating elements.
  • the invention relates also to some enhancing and cost reduction techniques of the pan detection system for cooking hobs with discrete distributed heating elements as disclosed in EP-A-1303168 .
  • the basic form of said receiving pickup coils or loops is that of one or more coils made of conducing metal wires or the like laying between the glass-ceramic slab and the heating elements.
  • This basic implementation even if it works in a satisfactory manner, nevertheless has some practical and technological problems that are addressed in this invention.
  • the basic known solution presents the following problems:
  • the spatial resolution of the system i.e. the ability of detecting only metallic objects lying just over the heating element and not in its surroundings, is generally poor if the pickup loops are significantly larger than the emitting coils which are also the heating elements.
  • the present invention solves all the above problems, providing a solution that is economical, easy to be produced, robust and guarantees high and reliable detecting performances. It is an object of the present invention to overcome or minimize the problem associated with the conventional pickup loops, providing a cheaper, more reliable and better performing solution.
  • the solution according to the invention solves all said issues by using a conductor (i.e. wire, track or the like) interposed between each couple of adjacent rows or columns of the matrix of heating elements, connecting means being provided for linking each loop to a detection circuit.
  • a conductor i.e. wire, track or the like
  • a pot detection system is based on the cross-inductive principle (or transformer principle), in which each receiving conductor is substantially different than a coil or loop, but it can assume the function of a coil by establishing, for instance by means of electronic multiplexers, a conductive path substantially encircling the magnetic field generated by the emitting coil of the heating element.
  • More than one receiving loop is used in order to detect a magnetically induced voltage, said coils being connected together at one or more points and sharing one or more linear conductors.
  • an electronic multiplexing circuit that can be used to detect -in distinct times- the voltages developed by magnetic induction in two of at least three points of an electrically conducting material, these two points being substantially equivalent to the terminals of a single turn coil enclosing the magnetic field generated by the emitting coil to be sensed.
  • the differential voltage developed at the free ends of each pair of legs is substantially equivalent to the differential voltage that would be developed at the ends of a coil embracing the same area delimited by the two addressed legs and the common conductor.
  • connection of each loop to the detection circuit may be performed through an electronic multiplexing technique in order to realize loop equivalent conducting paths, starting from non coil-shaped conductive paths, in a manner that will be explained in the following detailed description of different embodiments, given by way of non-limiting example, and illustrated in the accompanying drawings, in which:
  • a first embodiment of the invention is realized by creating a single turn pick-up loop or coil over each column of heating elements by sharing a common "leg" 10 between two adjacent columns, the shared leg being connected to the ground reference 5 of the detection circuit 3.
  • Said arrangement has the advantage that the number of vertical conductors is reduced from 2n to 1.5n, being n the number of loops to be sensed.
  • a third embodiment of the present invention can further reduce the number of vertical conductors needed to implement n sensing loops from 1.5n to n+1 .
  • Such embodiment is shown in figure 4 , in which the leg-sharing concept is extended to all the legs but the outer ones.
  • the receiving loops are realized by means of electronic multiplexing of the legs on a comb-shaped conductive structure substituting the regular coils of the previous solutions.
  • Said comb-like structure is made of a common edge 12, and a number of legs 2a,.., 21 substantially running parallel to the rows or the columns of heating elements to be sensed for pot presence.
  • the heating element 6 for sensing pot presence, the heating element 6 is used. As described in the prior art, an alternate current is flown into the coil of the heating element 6, thus generating a magnetic field leaking from the cell as a fountain.
  • the two electronic multiplexers 7a and 7b are addressed by a suitable electronic control, in order to switch into the differential amplifier 8 the two comb legs 2h and 2i adjacent to the cell 6. This is electrically equivalent to have a real loop wound around the column into which lies the cell 6.
  • FIG. 5 A substantially equivalent solution is shown in figure 5 , in which the comb structure is electrically floating and is brought to ground 5 by means of the electronic multiplexer 7b', while the other multiplexer 7a' connects the other leg to a ground referenced amplifier 8' connected to the detection circuitry 9.
