Cooking oven equipped with a core temperature probe adapted to be introduced in the food to be cooked and provided with a plurality of temperature sensors aligned with each other and adapted to deliver an electric signal correlated with the respective temperature, means for processing said electric signals, a support arrangement situated inside the cooking cavity of the oven for sustaining the core temperature probe, and means for measuring the temperature inside said cooking cavity, in which said core temperature probe, said processing means and said support arrangement are adapted to determine whether, during a cooking cycle, the core temperature probe is inserted in a given, pre-defined manner in the food being cooked.
In a preferred manner, the support arrangement is formed in a manner so that, when the core temperature probe is inserted in a pre-defined manner in said arrangement, some defined ones of said temperature sensors are covered by at least a portion of said support arrangement, while some other sensors are not covered.
