Cooking hob with discrete distributed heating elements

A cooking hob comprising a glass ceramic plate and an underlying plurality of electrical heating elements each having an electrical connection, the plurality of heating elements being disposed in matrix configuration and controlled by static switches, in order to be able to use at will any region of said hob for heating the contents of one or more cooking utensils, wherein a diode is present in series with each electrical heating element and an electronic control circuit is present for controlling the static switches, which receives process data from a touch screen connected to a video camera scanning the cooking hob.

A control method for a cooking hob comprising a glass ceramic plate and an underlying plurality of electrical heating elements each having an electrical connection, the plurality of heating elements being disposed in matrix configuration and controlled by static switches present in a number less than the number of heating elements, in order to be able to use at will any region of said cooking hob for heating the contents of one or more cooking utensils, said matrix comprising a diode in series with each resistance element and at least one printed circuit board (PCB) carrying tracks relative to each of the electrical connections, wherein the electrical heating elements are fed with line voltage in pulsed mode with a power substantially greater than a maximum allowable mean power, the matrix which represents in each pulsation the energy state of the heating elements (on-off) having unitary rank.
