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

Abstract

#CMT# # / CMT# The coffee machine has a foaming device (26), in which an inner milk channel to a foaming chamber is provided. The rinsing water from the continuous-flow water heater (15) is conveyed to a bypass air inlet (27) of the foaming device through a controlled valve assembly. The milk inlet end (28') of the milk inlet pipe (28) is directly or indirectly connected with a residual water dish (25) of the coffee machine in a fluid conducting manner. #CMT# : # / CMT# An independent claim is also included for a method for rinsing a milk inlet pipe connected to a foaming device, particularly a coffee machine. #CMT#USE : # / CMT# Coffee machine, particularly fully automatic espresso machine. #CMT#ADVANTAGE : # / CMT# The rinsing water from the continuous-flow water heater is conveyed to a bypass air inlet of the foaming device through a controlled valve assembly, and the milk inlet end of the milk inlet pipe is directly or indirectly connected with a residual water dish of the coffee machine in a fluid conducting manner, and hence ensures simple structure and simple handling of the coffee machine without danger and effective cleaning and rinsing of the milk intake hose. #CMT#DESCRIPTION OF DRAWINGS : # / CMT# The drawing shows a schematic view of the functional elements of the coffee machine. 15 : Continuous-flow water heater 25 : Residual water dish 26 : Foaming device 27 : Bypass air inlet 28 : Milk inlet pipe 28' : Milk inlet end.

Description

technical field [0001] The invention relates to a coffee machine with a bubbler, in particular to a fully automatic Espresso collautomat. [0002] An aspect of the invention also relates to a method for flushing a milk suction line connected to a frother, in particular a frother of a coffee machine. Background technique [0003] Coffee machines, in particular fully automatic espresso machines, are known from practice with a frother in which an inner milk channel leads to the frothing chamber, an outer movable A milk suction line, usually a hose, is connected in the milk channel, the suction end of which is in flow-conducting communication with, in particular plugged into, the milk storage container. The milk storage container may be a milk package made of cardboard. [0004] For hygienic reasons it is desirable to clean the milk-carrying parts of the frother and the milk suction line at infrequent intervals. For this purpose, hot rinsing water or steam is usually impinged...
