Patent ID: 8403306

Claim:
A device for foaming liquid foods in a container ( 8 ), comprising a source for a foaming medium and a discharge element ( 1 ) for the foaming medium to be at least partially inserted into the container ( 8 ), the discharge element ( 1 ) being connected to the source in a liquid-conducting fashion and comprising at least one fluid outlet opening ( 5 ) for discharging the foaming medium into the container ( 8 ), at least one motion element, which cooperates with at least one of the discharge element ( 1 ) or with a holder for the container ( 8 ) such that at least an elevation of the fluid outlet opening of the discharge element is adjustable in the container ( 8 ) via the motion element, the at least one motion element is an active motion element having a relative movement that is predetermined between the discharge element ( 1 ) and the container ( 8 ), a control unit for controlling the active motion element, and at least one sensor for detecting at least one of a surface of the liquid or a surface of the foam created, with the control unit being connected to the sensor and the active motion element such that the movement of the discharge element ( 1 ) can be controlled depending on measurements of the sensor.
