## Abstract

The present invention relates to an oven (1) comprising an exterior body (2), a cooking cavity (3) wherein the cooking process is realized, a heater (4) provides the foodstuff placed into the cooking cavity (3) to be cooked, a cooling fan (5) arranged between the exterior body (2) and the cooking cavity (3), that provides air circulation around the cooking cavity (3) and a control unit (6) that provides a cooking process composed of at least three phases, that is the first phase, second phase and third phase to be performed from the start to the end of the cooking.

## Claims

### Claim 1

An oven (1) comprising an exterior body (2), a cooking cavity (3) wherein the cooking process is performed, a heater (4) that provides foodstuffs placed into the cooking cavity (3) to be cooked, a cooling fan (5) arranged between the exterior body (2) and the cooking cavity (3), that provides air circulation around the cooking cavity (3), and a control unit (6) that performs the cooking process in at least three phases being the first phase, the second phase and the third phase from the start to end of the cooking, in the first phase at a first temperature (T1) defined by the user at the start of cooking process for a first phase duration (t1), in the second phase, at a second temperature (T2) lower than the temperature (T1) defined by the user for a second phase duration (t2) and in the third phase at a third temperature (T3) higher than the temperature in the first or second phase for a third phase duration (t3), characterized by the cooling fan (5), the activation of which is delayed by the control unit (6) until the end of the first phase and that is activated in the second phase.

### Claim 2 (depends on 1)

An oven (1) as in claim 1, characterized by the cooling fan (5) that is activated by the control unit (6) at the beginning of the second phase.

### Claim 3 (depends on 1)

An oven (1) as in claim 1, characterized by a temperature probe (7) used for measuring the inner temperature of the food being cooked in the cooking cavity (3) and the cooling fan (5) that is activated by the control unit (6) when the temperature change rate obtained from the data received from the temperature probe (7) reaches the limit temperature change rate determined by the producer

### Claim 4 (depends on 1)

An oven (1) as in claim 1, characterized by the cooling fan (5) that is activated by the control unit (6) when the temperature of the cooking cavity (3) measured from the beginning of the second phase reaches the critical temperature value obtained by the experimental studies performed by the producer.
