ABSTRACT:
This electric cooking oven for domestic use incorporates an electric circuit controlling the pyrolytic cleaning operation and comprising a pivoted blade-shaped shutter connected to a first control thermostat and to the cooling turbine connected in turn to a second thermostat so adjusted as to close at a predetermined critical temperature beyond which the turbine must be protected against overheating by ventilation, the second thermostat when open being coupled in turn to a resistance adapted to provide the heat necessary for performing the pyrolytic operation, so that the turbine is started automatically by the closing of the second thermostat at the critical temperature to cause the shutter to pivot to a position in which the shutter maintains the supply of electric power for energizing the turbine when the second thermostat opens, that is, when the oven temperature has dropped to a value lower than the predetermined critical temperature.
