Problems solved by technology
Such a device is expensive in construction and also has a relatively high energy consumption due to the separate heating elements for preparing coffee on the one hand and hot milk or milk froth on the other hand, especially for multiple applications in succession flow heating device
Accidents are therefore more prone to accidents, as empirically milk can easily stick in the pipes of continuous heating units

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 from the coiled tubing (13) 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.
Description
technical field [0001] The invention relates to a coffee machine for preparing coffee drinks or milk drinks with a boiler for generating hot water and steam. Background technique [0002] Such coffee machines are known in various implementations. Thus, for example, EF 0 761 150 describes a coffee machine which is provided with an outlet tap for brewed coffee and an outlet tap for drawing hot water or steam. Naturally, multifunctional devices are often required in use, which, in addition to coffee, also produce hot or cold milk or milk froth. For this it requires two different units, namely one for producing coffee and the other for producing milk or milk froth. Such a device is expensive in construction and also has a relatively high energy consumption due to the separate heating elements for preparing coffee on the one hand and hot milk or milk froth on the other hand, especially for multiple applications in succession Flow heating device. Accidents are therefore more p...
