Abstract

A cooking appliance includes a housing including a first compartment forming a cooking space, equipped with a holding device provided to receive ingredients, a stirring device arranged inside the holding device, the holding device and the stirring device being designed to be animated by a relative rotation with respect to each other, the housing further including a main heating device, including, in a second compartment, a ventilation system to generate a heating flow, wherein the ventilation system includes a cross-flow fan, and the main heating device includes at least one heating element arranged inside the first compartment.

First claim

The invention claimed is:

1. A cooking appliance comprising a housing comprising a first compartment forming a cooking space, equipped with a holding device provided to receive ingredients, a stirring device arranged inside the holding device, the holding device and the stirring device being configured to be animated by a relative rotation with respect to each other, the housing further comprising a main heating device, comprising, in a second compartment, a ventilation system configured to generate a heating flow, wherein the ventilation system comprises a cross-flow fan, and the main heating device comprises at least one heating element arranged inside the first compartment, and
wherein a longitudinal axis of the cross-flow fan is tangential to the first compartment.

2. The cooking appliance according to claim 1 , wherein the second compartment comprises an intake area upstream from the cross-flow fan, arranged between the cooking space and the ventilation system, and in communication with the ventilation system.

3. The cooking appliance according to claim 2 , wherein a height of the intake area is at least equal to a diameter of the cross-flow fan.

4. The cooking appliance according to claim 2 , wherein a width of the intake area is at least equal to 1.5 times a diameter of the cross-flow fan.

5. The cooking appliance according to claim 2 , wherein a distance between an axis of the cross-flow fan and an outer edge of the housing is at least equal to 0.7 times a diameter of the cross-flow fan.

6. The cooking appliance according to claim 1 , wherein the main heating device comprises a nozzle to guide the heating flow toward the holding device, the nozzle discharging into the first compartment.

7. The cooking appliance according to claim 6 , wherein the at least one heating element is arranged in the nozzle.

8. The cooking appliance according to claim 6 , wherein a distance between a perimeter of the cross-flow fan and an adjacent extremity of the nozzle is at least equal to 0.3 times a diameter of the cross-flow fan.

9. The cooking appliance according to claim 1 , wherein the housing comprises a lid pivotally mounted and covering the first and second compartments, the pivoting axis being positioned between the second compartment and an outer edge of the housing.

10. The cooking appliance according to claim 9 , wherein the main heating device comprises a nozzle to guide the heating flow toward the holding device, the nozzle discharging into the first compartment, and wherein the nozzle is integral with the lid and the ventilation system is fixed in the second compartment.

11. The cooking appliance according to claim 1 , wherein the housing comprises a lid pivotally mounted and covering at least the first compartment, a pivoting axis of the lid being positioned between the first compartment and the second compartment.

12. The cooking appliance according to claim 11 , wherein the lid covers only the first compartment and the ventilation system is fixed in the second compartment.

13. A cooking appliance comprising:
a housing comprising:
a first compartment forming a cooking space, equipped with a holding device provided to receive ingredients,
a stirring device arranged inside the holding device, the holding device and the stirring device being configured to be animated by a relative rotation with respect to each other,
a main heating device comprising, in a second compartment, a ventilation system configured to generate a heating flow,
wherein the ventilation system comprises a cross-flow fan, and the main heating device comprises at least one heating element arranged inside the first compartment,

wherein the housing comprises a lid pivotally mounted and covering the first and second compartments, the pivoting axis being positioned between the second compartment and an outer edge of the housing, and
wherein the main heating device comprises a nozzle to guide the heating flow toward the holding device, the nozzle discharging into the first compartment, wherein the nozzle is integral with the ventilation system and the ventilation system is configured to pivot in a same direction as the lid, a pivoting axis of the ventilation system being positioned between the first compartment and the second compartment.

14. A cooking appliance comprising:
a housing comprising:
a first compartment forming a cooking space, equipped with a holding device provided to receive ingredients,
a stirring device arranged inside the holding device, the holding device and the stirring device being configured to be animated by a relative rotation with respect to each other,
a main heating device comprising, in a second compartment, a ventilation system configured to generate a heating flow,

wherein the ventilation system comprises a cross-flow fan, and the main heating device comprises at least one heating element arranged inside the first compartment, and
wherein the housing comprises a lid, wherein the lid covers the first and second compartments, the ventilation system configured to pivot in a same direction as the lid, a pivoting axis of the ventilation system coinciding with a pivoting axis of the lid.
