Method for cleaning metering lines in automatically controlled laundry care devices

摘要

Flowable laundry treatment agents can be added in automatically metered dosages via a metering line to a laundry treatment process by means of an automatic metering system comprising a reservoir. Advantageously, a metering line of is flushed with a rinsing agent, particularly water, after adding a dose. In order to prevent the development of germs in the residues of the rinsing agents, comprising diluted residues of laundry treatment agents, when remaining in the fluid lines for a longer period of time, exemplary embodiments of the invention provide for the metering line to be flushed immediately before adding a dose.

主权项

1. An automatically controlled laundry care device, comprising:
a laundry treatment chamber within a housing; at least one reservoir, each configured to contain different flowable laundry treatment agents; a metering line; outlet lines connected to each reservoir and configured to supply the different flowable laundry treatment agents to the metering line; a rinsing line; a rinsing agent source configured to provide a rinsing agent; a rinsing agent controller configured to flush the metering line with the rinsing agent via the rinsing line from the rinsing agent source; and a laundry care device controller configured to initiate adding a metered dose of the different flowable laundry treatment agents from the reservoir without a post flush operation, and wherein after a delay period of time the laundry device controller is further configured to initiate a flushing by the rinsing agent controller, the flushing configured to occur only immediately before adding another flowable laundry treatment agent.
