Abstract
A cooking hob comprising a glass ceramic plate and an underlying plurality of electrical heating elements 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, in which a diode is present in series with each electrical heating element.
Claims15
A cooking hob comprising a glass ceramic plate and an underlying plurality of electrical heating elements 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.
A control method for a cooking hob comprising a glass ceramic plate and an underlying plurality of electrical heating elements 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, wherein the electrical heating elements are fed with line voltage in pulsed mode with a power substantially greater than the maximum allowable mean power, the matrix which represents in each pulsation the energy state of the heating elements (on-off) having unitary rank.
