Abstract
The steam generating device ( ) is used to heat and/or froth liquids, especially milk. It includes an electrically driven pump ( ) supplied with water from a water source ( ), which pump delivers water in a controlled fashion to a continuous flow heater ( ) heated by an electrically operated heating ( ) by way of a conduit ( ). The continuous flow heater ( ) heats the water it receives in its steam pipe ( ) to steam that is subsequently supplied to a steam tapping point, preferably a steam nozzle ( ), where the steam exits under pressure. An intermediate tank ( ) with an overflow chamber ( ) which stores a defined quantity of water is provided in the conduit ( ) between the pump ( ) and the steam pipe ( ). When the steam generating device ( ) is switched on, the pump ( ) is switched on simultaneously with the heating ( ), and after the switch-on the water delivered by the pump ( ) flows into the chamber ( ) of the intermediate tank ( ) and is retained there so long and is not delivered further to the continuous flow heater ( ) until the continuous flow heater ( ) has reached a temperature sufficient to evaporate water.
