Abstract: Domestic use food baking oven to be embedded is provided with a ventilation system for the thermal insulation of the baking chamber, an airflow control device of the heat dispersion from the baking chamber, and integrated ventilation system for the thermal insulation of the baking chamber. At the baking chamber access span, and in an operative baking condition with the baking chamber access door in an open condition, the forced airflow is generated by the ventilation system for the thermal insulation of the baking chamber, which is in a diverted condition at the baking chamber access span. The airflow is diverted by a flow diverter, being of the type which can be shut down as soon as the access door of the oven, in a closed condition, is arranged in abutment with the flow diverter or with a part of it.
