Abstract
A cooking device, in particular a steam oven, includes a cooking cavity and a heating unit. The heating unit has a first and a second heating element capable to operate at different temperatures, and at least one fan. The cooking device is configured in such a manner that the fan collects air from the cooking cavity and conveys a first airflow towards the first heating element and a second airflow towards the second heating element. The first airflow passing the first heating element creates a first airflow circuit in the cooking cavity, and the second airflow passing the second heating element creates a second airflow circuit in the cooking cavity. The two airflows can have different temperatures by individually controlling the power of the two heating element.
Claims20
A cooking device comprising:
- a cooking cavity,
- a heating cavity,
- a wall arranged between the cooking cavity and the heating cavity,
- ventilation openings located between the cooking cavity and the heating cavity,
- a heating unit arranged in the heating cavity and comprising a first and a second heating element and a first fan, wherein the first fan is positioned and adapted to collect air from the cooking cavity and to generate
- a first airflow interacting with the first heating element and being conveyed back into a first part of the cooking cavity, and
- a second airflow interacting with the second heating element and being conveyed back into a second part of the cooking cavity,
- a control unit adapted to operate the first and second heating elements independently from each other,
- wherein the heating unit comprises a second fan, and wherein the second fan is positioned and adapted to collect air from the cooking cavity and to convey said air towards the first and the second heating element,
- wherein at least one of the heating elements comprises at least one curved portion that extends essentially along a sector section of a rotation circle described by tips of blades of the first fan,
- wherein at least one of the heating elements comprises at least a second curved portion that extends essentially along a second sector section of a rotation circle described by tips of blades of the second fan.
