GERÄT ZUM ZUBEREITEN VON HEISSEN GETRÄNKEN

In an apparatus for the preparation of hot beverages, such as coffee, tea and the like, a heat source (16) heats a boiler (2) whose volume is a fraction of the volume of a fresh water container (1) and into which a rising pipe (7) is immersed from above. The boiler (2) fills with water via a connecting line (3) which is connected between the bottom of the fresh water container (1) and the lid of the boiler (2) and contains a float valve (4) upon which the boiler pressure acts in the closing direction and which blocks the connecting line (3) when the boiler (2) is full. When the boiling temperature is reached, the water flows due to steam pressure from the boiler (2) via the rising pipe (7) completely in one surge into a filter (11). Subsequently, the boiler (2) again fills suddenly with fresh water due to the vacuum occurring in the boiler when cold water flows in, which fresh water is then again heated to the boiling temperature. This operation is repeated several times until the entire quantity of water from the fresh water container (1) has been used up. The preparation of hot beverages thus takes place in a manner comparable to manual brewing of coffee in that hot water is conveyed into the filter (11) in surges at short intervals.
