ABSTRACT:
A cooking oven for foods is described, comprising a cooking chamber, a variable speed electric fan arranged for generating forced ventilation of the air inside the chamber, a regulating system for regulating the speed of the motor of the electric fan including at least one resistive electric element in the electrical supply circuit of the motor, in order to obtain the variation of the speed of the fan as a result of the electrical supply of the resistive element, wherein the resistive element is provided inside the cooking chamber of the oven, so that the heat generated by the resistive element is recovered and maintained within the cooking chamber in the thermal balance of the chamber, during the cooking of the foods.
