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).
Claims8
A domestic appliance constructed to process at least one foodstuff item present in a container,
- having a housing,
- having drive means, accommodated in the housing, for rotationally driving at least one tool of the domestic appliance,
- having at least one tool which is held by a holding means of the domestic appliance and then projects from the housing, which tool is drivable so as to be rotated about a tool axis with the aid of the drive means, is guided so as to be movable parallel to the direction of the tool axis, and has a free end which is remote from the housing, and
- having at least one spring means, for resiliently loading the at least one tool during rotational driving, namely in such a manner that the free end of the tool is resiliently urged away from the housing parallel to the direction of the tool axis,
- wherein blocking means have been provided for permitting user selection of normal operation in a movement-permitted mode, or normal operation in a movement-blocked mode preventing movement of the tool in the direction parallel to the tool axis,
- the blocking means are movable between a blocking position and a release position,
- each tool, when the blocking means are in their blocking position, is blocked against movement of the tool against the force of the spring means which loads the tool while still being normally operable, and
- each tool, when the blocking means are in their release position, is free to move against the force of the spring means which loads the tool.
