  • Patent number: 6663274
    Abstract: In a domestic appliance (1) having a housing (3) and having drive means (4) for rotationally driving at least one tool (5, 6) which is held by a holding means (17,18) and which is drivable with the aid of the drive means (4) so as to be rotated about a tool axis (31, 32), the tool (5, 6) is guided so as to be movable parallel to the direction of the tool axis (31, 32) and at least one spring means (39, 40) has been provided which resiliently loads a tool (5, 6) during rotational driving of this tool, namely towards the free end (33, 34) of the tool (5, 6).

  • Patent number: 6550958
    Abstract: A domestic kitchen appliance (1) comprises a container (2) with a central axis (3), a transmission frame (4) positionable on the container (2) and carries a drive element (5), a carrier element (6) which is rotatably journaled relative to the frame (4) about the central axis (3), and at least two coupling elements (7,8) which are rotatably journaled relative to the carrier element (6) about individual axes of rotation (17, 18), a transmission unit (9) carried by the transmission frame (4) for transmitting a rotation of the drive element (5) to a rotation of the carrier element (6) about the central axis (3) and rotations of the coupling elements (7,8) about their axes of rotation (17, 18), a drive unit (10) for driving the drive element (5), and at least two tools (27, 28) couplable to the coupling elements (7, 8). In the domestic kitchen appliance (1) in its assembled condition,the coupling elements (7, 8) are positioned on the carrier element (6) at different distances (a, b) from the central axis (3).
