Abstract: A kitchen appliance drive unit (10) is disclosed that comprises a housing (11) including a drive mechanism in the housing; a rotary member (31) driven by the drive mechanism, a first opening (13); a second opening (15) and an fluid pump (40) driven by the drive mechanism and being fluidly connected to the first and second openings, the fluid pump being arranged, in a first mode of operation, to displace a fluid from the first opening 5 (13) to the second opening (15), the fluid pump (40) also being arranged, in a second mode of operation, to displace fluid from the second opening (15) to the first opening (13).

Abstract: A kitchen appliance has a power unit 2 and a removable tool 4 connected through a mechanical interface 12. A controller 16 controls an electric motor 14 driving the tool 4 through the mechanical interface. A vibration sensor 18 identifies the vibrations of the tool and feeds the vibration data to the controller 16. The controller may use the vibration data to identify the tool and/or to select an appropriate drive pattern based on the sensed vibration.

Abstract: When food is being blended, chopped or cut using a hand blender, forces are executed from the tool unit onto the food and counterforces are executed from the food onto the tool unit (3). These forces are both in an axial and in a radial direction. The axial forces are being transmitted to the axial load bearing (23) located in the motor unit (2) of the hand blender (1). The transmission of the axial forces to the motor unit of the hand blender, instead of absorbing these forces in the tool unit, reduces the amount of heat dissipated in the tool unit. The radial forces are being absorbed by the bearing in the tool unit.
