Apparatus for agitating liquid foodstuff
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 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.
1. An apparatus for agitating liquid foodstuff, the apparatus comprising:
a whisk including a liquid foodstuff agitator;
a liquid foodstuff container, configured to at least partially receive the whisk such that the whisk is rotatable around an axis of rotation;
at least one sensor configured to provide a signal that reflects positional changes of the whisk relative to the at least one sensor; and
a controller configured:
to detect an initial, manually effected rotational movement of the whisk around the axis of rotation from the signal of the at least one sensor, and
once the initial, manually effected rotational movement of the whisk is detected, to operate a function of the apparatus independent of the initial, manually effected rotational movement of the whisk.
2. The apparatus according to claim 1 , wherein the controller is further configured to detect at least one parameter of the initial, manually effected rotational movement of the whisk.
3. The apparatus according to claim 2 , wherein the detected at least one parameter includes a clockwise or counter-clockwise direction of the initial, manually effected rotational movement of the whisk.
4. The apparatus according to claim 3 , wherein the controller is further configured to electromagnetically drive the whisk in rotation, such that a direction of the driven rotation of the whisk matches the clockwise or counter-clockwise direction of the initial, manually effected rotational movement of the whisk.
5. The apparatus according to claim 2 , wherein the detected at least one parameter includes a value indicative of an angular velocity of the initial, manually effected rotational movement of the whisk around the axis of rotation.
6. The apparatus according to claim 5 , wherein the controller is further configured to drive the whisk in rotation following the initial, manually effected rotational movement of the whisk, such that an angular velocity of the driven rotation of the whisk is dependent on the value.
7. The apparatus according to claim 2 , wherein the apparatus further comprises at least one temperature control element for controlling a temperature of liquid foodstuff in the foodstuff container, and
wherein the controller is operably connected to the at least one temperature control element and is configured to operate the temperature control element dependent on the detected at least one parameter of the initial, manually effected rotational movement of the whisk.
8. The apparatus according to claim 1 , wherein the whisk includes an elongate shaft having a first end that is connected to the liquid foodstuff agitator and a second end that defines a hand grip,
wherein the apparatus further includes a lid for closing off the liquid food container, and wherein the lid defines an opening, such that, when the whisk is operably received in the foodstuff container closed off by the lid, and the hand grip extends outward from the foodstuff container through the opening in the lid.
9. The apparatus according to claim 8 , wherein the lid is at least partially transparent.
