The cooking apparatus according to the present implementation comprises an extraction window forming an upstream end of a duct towards the outside of the appliance, to allow water vapor to escape from the appliance. cooking space. The orientation of the extraction window is chosen so that the flow of air which has a tangential component at the outlet of the centrifugal turbine impinges on the extraction window. In other words, the extraction window is not parallel to a tangent of a circle centered on the centrifugal turbine and passing through the center of the extraction window, which avoids having to implant in space cooking a deflector oriented towards the extraction window for example.
    The center of the extraction window is understood to mean the median or mid or equidistant zone of the edges of the extraction window, in a plane of projection perpendicular to the axis of rotation of the centrifugal turbine.
    Advantageously, the extraction window is arranged facing an exhaust zone of the centrifugal turbine.
    Advantageously, the extraction window has at all points of its passage surface a normal direction oriented at an angle in a range from 110 ° to 125 °, and more preferably from 110 ° to 118 °, relative to the direction tangential to the circle centered on the centrifugal turbine and passing in the center of the extraction window. The Applicant has determined that this orientation allows for optimal extraction of water vapor.

    In other words, the invention also relates to a food cooking apparatus comprising: - a centrifugal turbine arranged to create an air flow in a cooking space. a steam extraction window arranged to extract out of the appliance the steam present in the cooking space; a steam extraction duct arranged between the extraction window and the outside of the cooking space; the cooking apparatus and having a longitudinal direction, characterized in that the extraction window has at all points of its passage surface a normal direction oriented with respect to the longitudinal direction of the steam extraction duct at an angle in a range from 20 ° to 35 °, and more preferably from 20 ° to 28 °.
    Advantageously, the extraction window and / or the extraction duct are directly formed by a partition defining the cooking space. This implementation limits the additional parts and related assemblies.
    Advantageously, the cooking space comprises an upper portion of the cooking space formed by an upper partition comprising at least one plane face and parallel to an axis of rotation of the centrifugal turbine, on which the extraction window is arranged, and the extraction window is oriented with respect to the flat face by an angle in a range from 20 ° to 35 °, and more preferably from 20 ° to 28 °.
    In other words, the invention also relates to a food cooking apparatus comprising: - a centrifugal turbine arranged to create an air flow in a cooking space, - a steam extraction window arranged to extract to outside the apparatus of the steam present in the cooking space, - an upper portion of the cooking space formed by an upper partition comprising at least one flat face and parallel to an axis of rotation of the centrifugal turbine , on which is arranged the extraction window, characterized in that the extraction window is oriented relative to the flat face by an angle in a range from 20 ° to 35 °, and more preferably 20 ° at 28 °.
    Advantageously, the extraction window is formed by a planar grid. Such a window is simple to manufacture.
    Advantageously, the centrifugal turbine comprises a plurality of blades, and the extraction window has at least one portion arranged at a distance of less than 10 mm and preferably less than 5 mm from one end of the blades. This implementation makes it possible to increase the extraction efficiency by imposing a proximity between the extraction window and the centrifugal turbine.
    Advantageously, the cooking apparatus comprises a housing and a removable cooking basket relative to the housing and arranged to receive food to be cooked, wherein the cooking basket is movable in translation relative to the housing, in a direction perpendicular to the housing. axis of rotation of the centrifugal turbine.
    Advantageously, the cooking apparatus comprises heating means, arranged between the cooking basket and the centrifugal turbine.
    Advantageously, the extraction window is arranged on one side of the cooking appliance opposite a side where the cooking basket can be grasped by a user. The extraction window is the opposite of the area where the user evolves, which improves safety, and it also avoids having condensation on the walls visible to the user.
    Advantageously, the cooking basket is mounted in sliding connection relative to the housing.
    Advantageously, the cooking appliance comprises sealing means arranged between a door integral with the cooking basket and the housing of the appliance. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawings, in which: - Figure 1 shows a sectional view of a cooking appliance according to the invention with a cooking space comprising a centrifugal turbine and a steam extraction window; FIG. 2 represents a perspective view of a rear face of the apparatus of FIG. 1; FIG. 3 represents a view from below of an upper part of the cooking space of the apparatus of FIG. 1.
    FIG. 1 represents a sectional view of an air-flow cooking apparatus, which comprises a centrifugal turbine 2, arranged in a cooking space formed by an upper cavity 3 and a tank 11. The tank 11 as well as a cooking basket 10 are removable relative to a housing 7. These elements are guided in translation along a guide formed by a cooking chamber 12 and a ring 5. The assembly is extracted by the front of the device (on the left of figure 1), using a handle, visible figure 1.
    Cooking food is done in the cooking basket 10. The air of the cooking space is heated by means of a resistor 9 and then set in motion in this cooking space by the centrifugal turbine 2 connected for this purpose to a motor 6. The air is sucked by the cooking basket 10 via a deflector 8. It is heated to the passage of the resistance 9. The air is then propelled radially on the walls of the upper cavity 3 by the centrifugal turbine 2 The heated air descends along the wall of the upper cavity 3 and the tank 11 before supplying heat to the food in the cooking basket 10. Arrows in Figure 1 schematize the path of the air flow .
    However, it should be noted that due to the rotational movement of the centrifugal turbine 2, the air flow at the outlet of the centrifugal turbine 2 and down along the wall of the cooking chamber 12 is also rotating, that is to say, it follows a propeller or cyclonic movement.
    In order to avoid overpressures due to the appearance of steam during cooking (water evaporates from the food to be cooked), an extraction window 1 is provided at the level of the upper cavity 3 , opposite an exhaust zone of the centrifugal turbine 2. The steam formed during the cooking of the food escapes through the extraction window 1 and then by an extraction duct 13 at the upper rear part of the cooking chamber, visible figure 2. Thus the steam can escape from the back, opposite the handle and the front face, which avoids any interference with the user and any condensation on the face before.
    In order to best guide the moist air towards the extraction duct 13, the invention proposes a particular arrangement of the extraction window 1 in the upper cavity 3, as can be seen in FIG.
    The extraction window 1 is assembled on the upper cavity 3 in front of the exhaust of the centrifugal turbine 2 (a portion of the blades has been masked for the sake of clarity). The vent grille forming the extraction window 1 is judiciously oriented in order to capture a maximum of the output flow of the centrifugal turbine 2 which has a radial component, but also a tangential component T.
    The Applicant has defined a minimum angle α of 20 ° and a maximum of 35 ° between the extraction window 1 and the flat rear face of the upper cavity 3. Ideally, an angle α of 24 ° ± 4 ° will be preferred.
    Alternatively, an angle a2 between a normal direction N at the extraction window 1 and a tangential direction T of a circle (C) centered on the centrifugal turbine 2 and passing through the center of the extraction window 1 is between 110 ° and 125 °, and is ideally in the range of 110 ° to 118 °.
    Finally, it can be seen from FIG. 3 that the extraction window 1 is advanced in the upper cavity 3 to be as close as possible to the blades of the centrifugal turbine 2, in order to capture as much water vapor as possible. A distance can be provided between the extraction window 1 and the blades of the centrifugal turbine 2 less than 10 mm, and more preferably less than 5 mm.
    In summary, the invention provides an efficient extraction of water vapor created during cooking due to the orientation of the extraction window which is not parallel to the tangential direction of the circle concentric with the centrifugal turbine 2 and passing through the middle of the extraction window, as well as thanks to the proximity of the extraction window with the blades of the centrifugal turbine 2, the extraction window 1 forming an upstream end of a conduit to the outside of the device.
    It will be understood that various modifications and / or improvements obvious to those skilled in the art can be made to the various embodiments of the invention described in the present description without departing from the scope of the invention defined by the appended claims.
