Abstract
The beverage appliance of the present invention includes a venturi having a steam inlet and a milk inlet. The steam inlet and milk inlet each include a solenoid valve configurable between an open state and a closed state. The solenoid valves are electrically coupled to a processor and are controllable through first and second switches. In operation, upon activation of the first switch, the solenoid valves are controlled to their open states to deliver milk and steam to the venturi to produce frothed milk. When a desired amount of frothed milk has been dispensed, the user deactivates the first switch and the processor controls only the milk inlet solenoid valve to its closed state. The steam inlet solenoid valve remains in its open state for a predetermined amount of time such that a burst of steam only is forced through the venturi and distribution lines to purge them of milk.
