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.

The invention relates to a novel excitation circuit for a synchronous generator. When the generator is excited, the switch S of the excitation circuit is turned on, and the voltage of the excitation power source Eb is sent to the rotor excitation circuit UE of the generator, so as to generate electricity. The machine obtains the initial excitation current, and the machine end excites the AC voltage. The Ua, which is depressurized by the secondary end of the rectifier transformer, is added to the rectifier BR through the first and second terminals. After rectification, the DC is input to the rotor excitation circuit UE. In the process, the generator voltage increases, which is a positive feedback process. When the secondary terminal voltage Ua of the rectifier transformer increases enough to enable the AVR to start working, the thyristor SCR rectification can be triggered, and the loop is automatically transferred to the thyristor rectifier. In the normal excitation mode, the excitation circuit is also automatically disconnected at this time, and the excitation is completed. By introducing an external excitation power source BT, the generator excitation and voltage building process can be completed quickly and reliably.
