| 20110014338 | MACHINE FOR PREPARING HOT BEVERAGES AND METHOD FOR OPERATING SUCH A MACHINE - A machine for preparing a hot beverage includes a water tank having a reservoir which contains water to be heated. Disposed downstream of the reservoir in a flow direction of the water is a lead container from which water is discharged into a pipe which is heated by a heating unit, thereby partly evaporating water to produce steam for further transport of water. In order to maintain a constant brew temperature, the water level is maintained in the lead container at a desired value. | 01-20-2011 |
