In a domestic appliance ( ) having a housing ( ) and having drive means ( ) for rotationally driving at least one tool ( ) which is held by a holding means ( ) and which is drivable with the aid of the drive means ( ) so as to be rotated about a tool axis ( ), the tool ( ) is guided so as to be movable parallel to the direction of the tool axis ( ) and at least one spring means ( ) has been provided which resiliently loads a tool ( ) during rotational driving of this tool, namely towards the free end ( ) of the tool ( ).

Domestic appliance having spring-loaded tools

A domestic kitchen appliance ( ) comprises a container ( ) with a central axis ( ), a transmission frame ( ) positionable on the container ( ) and carries a drive element ( ), a carrier element ( ) which is rotatably journaled relative to the frame ( ) about the central axis ( ), and at least two coupling elements ( ) which are rotatably journaled relative to the carrier element ( ) about individual axes of rotation ( ), a transmission unit ( ) carried by the transmission frame ( ) for transmitting a rotation of the drive element ( ) to a rotation of the carrier element ( ) about the central axis ( ) and rotations of the coupling elements ( ) about their axes of rotation ( ), a drive unit ( ) for driving the drive element ( ), and at least two tools ( ) couplable to the coupling elements ( ). In the domestic kitchen appliance ( ) in its assembled condition,the coupling elements ( ) are positioned on the carrier element ( ) at different distances (a, b) from the central axis ( ). Thus, one tool processes the substance present near a center part of the container ( ), and the other tool processes the substance present in the vicinity of a wall ( ) of the container ( ). This benefits the processing of the entire substance present in the container ( ), which improves the overall processing results, while a relatively simple construction of the appliance is achieved.
