Abstract
A mixing appliance includes a motor having a rotatable drive shaft coupled to a gearbox having a rotatable output shaft. The gearbox includes a first gear train having a first output speed ratio and a second gear train having a second output speed ratio. A controller module is communicatively coupled to an actuator arranged to selectively trigger a shifter member to shift an engagement of the first gear train or the second gear train to the other of the first or second gear train.
Claims20
A mixing appliance, comprising:
- a housing;
- a motor located in the housing and having a rotatable drive shaft;
- and
- a gearbox located in the housing, having an input side and an output side, the gearbox including a rotatable output shaft, the rotatable output shaft axially aligned with and rotatably coupled to the rotatable drive shaft at the input side, wherein the gearbox includes a first gear train having a first output speed ratio and a second gear train having a second output speed ratio;
- a shifter member moveably coupled to an input gear, the shifter member selectively moveable between a first shifter position and a second shifter position;
- wherein, in response to a first movement of the shifter member to the first shifter position, the input gear is moveable in a first direction to be disengaged from a second gear, and a first gear is moveable in the first direction to be disengaged from a third gear, to define the first gear train of the gearbox;
- and
- wherein in response to a second movement of the shifter member to the second shifter position, the input gear is moveable in a second direction to be in rotatable engagement with the second gear, and the first gear is moveable in the second direction to be in rotatable engagement with the third gear to define the second gear train of the gearbox.
A method of operating a mixing appliance, the mixing appliance having a controller module and a motor configured to rotate a rotatable drive shaft rotatably coupled to an output shaft via a gearbox, the gearbox including a first gear train having a first output speed ratio and a second gear train having a second output speed ratio, the gearbox selectively shiftable between an engagement of the a first gear train and an engagement of the second gear train, the method comprising:
- receiving at the controller module a first input signal;
- selecting, by the controller module, a predefined operation based on the first input signal;
- and
- triggering a shifter member of the gearbox to shift from an engagement of the first gear train or the second gear train to an engagement of the other of the first or second gear train, based on the selected predefined operation.
