Claims15
A food preparation appliance comprising:
- a food preparation vessel;
- a lid which can be placed on the food preparation vessel;
- an attachment part which can be placed on the food preparation vessel instead of the lid, the attachment part comprising a first part and a second part;
- a base part for receiving the food preparation vessel, the base part comprising a locking device for locking the lid placed on the food preparation vessel and for locking the attachment part placed on the food preparation vessel, wherein, in a locked state, the lid or the attachment part which has been locked to the food preparation vessel cannot be removed from the food preparation vessel;
- and
- a sensor which is triggered when the placed lid is locked by the locking device or when the placed attachment part is locked by the locking device, wherein the sensor is not triggered when only one part of the attachment part is placed on the food preparation vessel and locked, and
- wherein the sensor includes an electrical switch with a rocker arm on which the attachment part rests when the attachment part is placed on the food preparation vessel.

- a sensor including an electrical switch with a rocker arm on which the attachment part rests when the attachment part is placed on the food preparation vessel,
- the method comprising:
- placing the lid or the attachment part on the food preparation vessel of the food preparation appliance;
- locking, after placing, the lid or the attachment part to the food preparation vessel;
- triggering the sensor when the lid is locked to the food preparation vessel;
- not triggering the sensor when only one of the parts of the attachment part is locked to the food preparation vessel;

- chopping a food using the locked attachment part after the sensor has been triggered.
10 more elements
A food preparation appliance comprising:
- a food preparation vessel;
- a lid which can be placed on the food preparation vessel;
- an attachment part placeable on the food preparation vessel instead of the lid, the attachment part including a first part and a second part and configured to chop or blend a food in the food preparation vessel;
- a base part for receiving the food preparation vessel, the base part comprising a locking device for locking the lid placed on the food preparation vessel and for locking the attachment part placed on the food preparation vessel, wherein, in a locked state, the lid or the attachment part which has been locked to the food preparation vessel cannot be removed from the food preparation vessel;
- and
- a sensor configured to
