Coffee machine with frothing device and method for cleaning milk suction line

Abstract

The invention relates to a coffee machine with a frothing device, especially relates to an automatic espresso coffee machine. The frothing device is provided with an internal milk channel leading to a frothing chamber, a bypass air inlet for operable air supply for the frothing device, a movable milk suction line leading to a milk storing container, and a cleaning device which cleans the frothing device and the milk suction line by using flush water from a continuous type heater of the coffee machine. The flush water from the continuous type heater can be supplied to the bypass air inlet of the frothing device through a valve structure under control. Before the flush water is loaded at the bypass air inlet, the milk suction end of the milk suction line can be directly or indirectly communicated with a remaining water tank of the coffee machine. The invention also relates to a method for cleaning the movable milk suction line connected to the frothing device, especially to the frothing device of the coffee machine.
