Definitions

  • the present invention relates to tools for dough kneading and chopping in food processors.
  • Food processors are normally able to perform several different tasks by using different tools operating in the food processor.
  • tools such as knife tools, dough kneading tools, whipping tools, shredding tools etc.
  • knife tools for example, by applying a knife tool in the food processor, chopping can be performed and by applying a dough tool, dough kneading can be performed in the food processor.
  • a drawback with known technique is that storage of such tools, in particular if having many, is rather space taking, especially when considering that each tool typically comprises both a shaft connectable to the driving arrangement in the food processor and a tool part (such as the knifes or blades).
  • An object of the present invention is to provide an improved alternative to the above mentioned technique and prior art. More specifically, it is an object of the present invention to provide an accessory and a tool for a food processor which requires a reduced storage space. It is also an object of the present invention to provide a food processor comprising such a tool.
  • a dough kneading accessory for a food processor is provided.
  • the dough kneading accessory comprises a blade adapted to fit on a knife tool for the food processor and cover at least a cutting edge of the knife tool, and a fixing means (or attachment means) for fixing (or attach) the blade to the knife tool.
  • a combined knife and dough tool for a food processor comprises a knife tool having a shaft adapted to be rotated by the food processor, and a knife attached to the shaft, wherein the knife has a cutting edge, and a dough kneading accessory according to the first aspect of the invention.
  • a food processor comprises a combined knife and dough tool according to the second aspect of the invention.
  • the present invention is based on the idea of providing a dough kneading accessory which can be attached to a knife tool and thereby obtain a single, combined tool.
  • the combined tool can be interchanged between two different operation modes and thereby perform two different tasks, namely chopping and kneading, in the food processor.
  • the appliance of the dough kneading accessory i.e. by applying it to the knife tool
  • the coverage of the cutting edge of the knife tool by the dough kneading accessory transforms the sharp chopping knife into a less sharp blade suitable for dough kneading.
  • the present invention is advantageous in that the dough kneading accessory has a reduced size compared to known dough tools comprising both kneading blades and a shaft.
  • the shaft of the knife tool is utilized also for the dough kneading tool. Hence, storage of the tools for the food processor requires a reduced space.
  • the present invention is advantageous in that it facilitates shifting the food processor between different operations modes, namely between chopping and kneading.
  • the dough kneading accessory may simply be attached or detached to the knife tool for shifting between the different operation modes.
  • the present invention is advantageous in that the dough kneading accessory can be used as a protective cover when applied to the knife tool, in particular when the tool is not operating.
  • the dough kneading accessory may protect users from the sharp cutting edge of the knife and also the cutting edge from being blunt by contact with metal objects, such as cutleries and other kitchen tools, during storage.
  • the present invention is also advantageous in that, when the dough kneading accessory is applied to the knife tool, the (metal) knife forms a stiff core of the dough tool blade, thereby providing a robust dough kneading blade.
  • the blade may comprise a recess adapted to receive a knife of the knife tool. Hence, the knife may be inserted in the recess for applying the dough kneading
  • the recess may be adapted to the shape of the knife and extend along a longitudinal direction of the blade of the dough kneading accessory.
  • the recess may be adapted to extend along the cutting edge (of the knife), thereby providing an improved fit to the knife tool.
  • the fixing means may be adapted to fix the knife in the recess, thereby providing a firm attachment of the blade of the dough kneading accessory to the knife, which reduces the risk of the blade to come loose from the knife.
  • the blade (of the dough kneading accessory) may be chamfered towards an edge of the blade, which edge is adapted to cover the cutting edge of the knife tool.
  • the chamfered edge of the blade may cover the cutting edge of the knife.
  • the present embodiment is advantageous in that the chamfered edge improves the dough kneading performance of the tool.
  • the chamfered edge is provided at the edge of the blade adapted to be the leading edge upon rotation of the tool.
  • the dough kneading accessory may further comprise a ring connected to the blade and adapted to be arranged around a shaft of the knife tool.
  • the present embodiment is advantageous in that the ring may contribute to the fixing of the dough kneading accessory to the knife tool.
  • the ring may be threaded on to the shaft of the knife tool when applying the dough kneading accessory.
  • the dough kneading accessory may further comprise a second blade being adapted to fit on the knife tool, and to cover at least a second cutting edge of the knife tool.
  • the present embodiment is advantageous in that two, preferably opposing, blades provides an improved balance upon rotation of the tool.
  • most knife tools for food processors include two knifes.
  • the dough kneading accessory may comprise any number of blades corresponding to the number of knifes of the knife tool.
  • the two blades may be, preferably rigidly, interconnected, for example by the ring adapted to be arranged around the shaft of the knife tool.
  • the present embodiment is advantageous in that the dough kneading accessory may be provided in a single piece.
  • the dough kneading accessory may be moulded in a single piece, which may facilitate manufacturing of the dough kneading accessory.
  • the blades may not be interconnected, but instead realized as two separate parts, wherein each blade may be separately attachable to a knife of the knife tool.
  • the fixing means may comprise one or more of: a snap fit (e.g. provided in the blade), an interference fit (or press or friction fit) and a bayonet mount (e.g. formed by a slot in the dough kneading accessory and a pin on the shaft of the knife tool).
  • the fixing means may be realized in any way to fix the blade to the knife tool.
  • the fixing means may be an interference fit between the knife and the recess.
  • the recess may then be slightly narrower than the thickness of the knife, and slightly flexible, such that the fixing of the blade in the recess is provided by the friction between the knife and the area of the blade defining the recess. Hence, the knife may be pressed into the recess and the friction will retain it there. Further examples of means for fixing the blade to the knife tool will be described in the detailed disclosure.
  • the dough kneading accessory may comprise plastic and/or rubber material, which is
  • the dough kneading accessory may be attachable to the knife tool (such that the cutting edge is covered by the blade).
  • the knife tool may be transformed into a dough tool by attaching the dough kneading accessory to the knife tool.
  • the combined knife and dough tool may be in a dough kneading mode when the dough kneading accessory is attached to the knife tool and in a chopping mode when no additional accessory (such as the dough kneading accessory) is attached to the knife tool.
  • the present embodiment is advantageous in that it provides two different operation modes for the food processor with a single combined knife and dough tool.
