Coffee Machine

Abstract

The invention relates to a coffee machine comprising a boiler (1) for producing hot water and steam for the preparation of coffee or coffee-containing beverages. A coiled tubing (13) is located in the boiler for producing hot milk or milk froth. Thus, no separate heating element is required for producing the hot milk or milk froth, as the milk or milk froth is heated by the water heated in the boiler for preparing the coffee. The coiled tubing (13) is connected alternately to a milk container (8) and a rinsing water source (25), so that potential milk residue is flushed out after each milk heating process. A predetermined amount of milk or rinsing water is fed to the coiled tubing (13) by a pump (10). Thus the milk and rinsing water usage is optimized and the energy consumption is reduced.
