Abstract:
1. An automatic milk foamer comprising: a container to receive milk, the container having an interior, a bottom, and a wall that circumscribes the bottom of the container; a base on or in which the container can be placed; a ring-shaped stirring device that can be used in the container to foam the milk, the stirring device being swivel-coupled with a motor via a non-contact magnet coupling; and a heating device to heat the milk present in the container, the base having a wall section and a bottom, the wall section running essentially parallel to the container wall and forming a depression to receive the container, the motor to drive the stirring device provided in the base, the heating device including an alternating field generator in the base to generate a magnetic alternating field, with the alternating field generator being arranged behind the wall section that forms the depression and designed as a ring-shaped induction coil that surrounds the wall section at least in part, the container wall including a ferromagnetic material, electrically conductive material, or both so that the container can be heated due to the magnetic alternating field, a container-raised part that stretches upwards axially provided on the container bottom, the bottom of the depression having a bottom-raised-part that engages the container-raised-part of the container when the container is inserted in the depression, the container-raised part serving as a bearing pin for the stirring device, a shaft powered by the motor, the shaft positioned on a side of the bottom-raised-part that faces away from the interior of the container, the shaft having a magnetic or a ferromagnetic material and jutting out into the bottom-raised-part, the stirring device having ferromagnetic or magnetized sections, the ferromagnetic or magnetized sections being provided in the interior of the container, radially opposite the magnetic or ferromagnetic material of the shaft, and acting together with the magnetic or ferromagnetic material of the shaft in such a way that when the shaft turns, the stirring device is placed in a rotating motion; wherein the bottom-raised-part includes a sidewall and an upper wall completely covering the shaft.
