Abstract

An apparatus for agitating liquid foodstuff, comprising a whisk that includes a magnetic rotor of a brushless electromotor assembly, and a main body including a liquid foodstuff container in which the whisk is receivable such that it is rotatable around a rotation axis (L) thereof, and a stator of the electromotor assembly. The stator is configured to electromagnetically drive the rotor in rotation, and includes at least one magnetic sensor configured to provide a signal that reflects positional changes of the magnetic rotor relative to the magnetic sensor. The main body also includes a controller configured to detect an initial, manually effected rotational movement of the whisk around its rotation axis from the signal of the magnetic sensor, and, once such initial movement of the whisk is detected, to operate the apparatus independent of said initial, movement.

Dependent claims

An apparatus for agitating liquid foodstuff, the apparatus comprising:

a whisk, including:
a liquid foodstuff agitator;
a rotor of an electromotor assembly, wherein the rotor is connected to the liquid foodstuff agitator, and includes at least one rotor magnet;
a main body, including:
a liquid foodstuff container, configured to at least partially receive the whisk such that the whisk is rotatable around a rotation axis thereof;
a stator of the electromotor assembly, said stator being configured to electromagnetically drive the rotor in rotation, and including at least one magnetic sensor configured to provide a signal that reflects positional changes of the at least one rotor magnet relative to the magnetic sensor;
and
a controller, operably connected to the stator of the electromotor assembly, and configured
to detect an initial, manually effected rotational movement of the whisk around the rotation axis from the signal of the magnetic sensor;
and
once the initial, manually effected rotational movement of the whisk is detected, to operate the apparatus independent of said initial, manually effected rotational movement of the whisk.
