    The present invention relates to the field of small household appliances intended for heating food containers and / or for cooking food and / or for preparing food. Preferably, the invention applies to the field of small household appliances for childcare but in a non-exclusive manner.
    Kitchen appliances such as food processors conventionally include a food preparation bowl which can also be used for cooking food. To prepare food, the bowl conventionally comprises a blade configured to be driven in rotation by a rotary drive shaft formed in the bottom of the bowl. The blade is arranged on a blade holder which can either be fixedly integrated on the drive shaft or removably by a locking system.
    The integrated blade holders have the disadvantage of not being removable, which makes cleaning the blades and the space between the blade holder and the bowl bottom, tedious and approximate. In addition, as the blade holders are permanently installed, it is not possible to change the blade in the event of a defect or wear.
    Removable blade holders are usually locked to the bottom of the bowl via a locking nut or bayonet system. The advantage of these blade holders is that they can be easily changed and removed to clean the bottom of the bowl. However, these blade holders have the drawback of having a complex structure requiring a metal surface on which the blade rests for friction, and comprises a plurality of seals and parts which complicate the mounting.
    The invention aims to remedy all or part of the aforementioned drawbacks by providing a removable blade holder whose structure is simplified.
    To this end, the subject of the invention is a blade holder for a food processor intended for at least the preparation of food, the blade holder being configured to be removably positioned in a bowl for preparation and / or cooking food from a food processor, the blade holder comprising:
    at least one locking member configured to lock the blade holder in a bowl, at least one blade comprising at least one first knife and at least one second knife a support comprising at least one shaft extending along a longitudinal axis of the holder blade, the blade being mounted on the support around the shaft, characterized in that the blade comprises a central portion from which extend the first knife and the second knife radially the central portion of the blade comprising an orifice passage of the support shaft, the central portion comprising a first face on which the support is positioned and a second face, opposite the first face, configured to cooperate with a first seal, positioned between the locking member and the portion blade center.
    The structure of the blade holder according to the invention is simplified in particular because the blade comprises a central portion acting as a washer which makes it possible to overcome the metallic friction surface, and thanks to the configuration with a first seal, there is no 'is no longer necessary to have a first seal before and after the blade to ensure the watertightness of the blade holder. Advantageously, the central portion of the blade acts as a metal washer which is resistant to friction and to heating due to the rotation of the blade holder.
    Advantageously, the configuration of the blade with two knives improves the cutting efficiency of food in the bowl.
    According to one embodiment of the invention, the second knife extends radially from the central portion of the blade in a different direction, preferably opposite, to that in which the first knife extends.
    According to one embodiment of the invention, the second knife is arranged symmetrically with the first knife with respect to the central portion of the blade. Thus, the cutting of food is more efficient and this symmetrical configuration balances the blade.
    According to one embodiment of the invention, the blade can comprise a plurality of knives, the knives being balanced around the central portion.
    According to one embodiment of the invention, the blade is overmolded or force-fitted on the support shaft.
    According to one embodiment of the invention, the blade is made of metal and preferably of steel.
    According to one embodiment of the invention, the central portion of the blade is permanently fixedly mounted on the support.
    According to one embodiment of the invention, the central portion of the blade is molded into the support.
    According to one embodiment of the invention, the support comprises a first portion on which the shaft is formed, said first portion being arranged opposite the second face of the blade in the mounted state of the blade holder.
    According to one embodiment of the invention, the support further comprises a gripping member arranged on the first portion of the support. The gripping member advantageously makes it possible to handle and remove the blade holder from the bowl without risk of injury.
    According to one embodiment of the invention, the gripping member is in the form of a projecting lug, preferably rectangular, extending from the first portion along the longitudinal axis of the blade holder.
    According to one embodiment of the invention, the shaft is configured to be rotated relative to the locking member by a drive shaft in the bowl.
    According to one embodiment of the invention, the locking member comprises at least one upper portion comprising a first face shaped to receive the first seal.
    According to one embodiment of the invention, the upper portion of the locking member further comprises a receiving groove shaped to accommodate at least a second seal, said receiving groove being arranged at a second face of the upper portion, opposite the first face.
    According to one embodiment of the invention, the locking member comprises a lower portion shaped to cooperate with part of the bowl for preparing and / or cooking food.
    According to one embodiment of the invention, the lower portion comprises at least a first deformation and at least a second deformation, each intended to cooperate with a complementary shape formed on the bowl for preparing and / or cooking food, the first deformation and the second deformation each being part of a bayonet locking system.

    According to one embodiment of the invention, the blade holder further comprises a second seal configured to seal between the blade holder and the bowl for preparing and / or cooking food.
    According to one embodiment of the invention, the second seal is a lip seal or an O-ring or flat seal.
    According to one embodiment of the invention, the locking member comprises a first bore shaped to accommodate the support shaft. Alternatively, the locking member may comprise a plain bearing configured to accommodate the shaft of the support.
    According to one embodiment of the invention, the locking member comprises a second bore, adjacent to the first bore, the second bore being shaped to accommodate a locking collar.
    According to one embodiment of the invention, the second bore is formed at least at the level of the lower portion of the locking member.
