Definitions

  • Method for cleaning dosing lines in automatically controlled laundry treatment machines in which flowable laundry treatment agents are supplied from at least one reservoir in machine-sized doses via a dosing to a laundry treatment process, which are rinsed after supplying a dose by means of a rinsing agent, in particular by means of water can.
  • dosing line - those line areas which are wetted by a respectively metered laundry treatment agent - hereinafter referred to as dosing line - are rinsed after its addition with said rinsing agent (water, especially fresh water). All known measures for rinsing the dosing is common, however, that remain after rinsing residues of the mixture of fresh water and small portions of the just rinsed laundry treatment agent. This can lead to a multiply increased nucleation potential, especially when using organic chemicals (eg detergent surfactants).
  • organic chemicals eg detergent surfactants
  • the invention has for its object to set up a method of the type described above so that the above hazards can no longer occur.
  • residues of diluted laundry treatment agents can form germs and that different proportions in the rinse solutions can react with one another and their reaction results seriously disturb the further process in a laundry treatment machine.
  • this object is achieved by the characterizing features of claim 1 in such a way that the dosing is rinsed immediately before supplying a dose.
  • a compulsory controller of the laundry treating machine may be informed of the characteristics of the respective laundry treating agent and only make a rinse if the following laundry detergent to be dosed may react with the preceding laundry.
  • a flushing of the dosing line could be made dependent on how long the immediately preceding supply of a dose is behind and / or how fast the laundry treatment agent of the immediately preceding dosing dries, sediments or thus increments its state of aggregation. Namely, if the likelihood of reactions between the doses of successive laundry treating agents or a change in state of aggregation makes rinsing obsolete, it may be omitted. This saves water and time.
  • a rinse may also be applied in more than one step according to a further development of the invention. This may be beneficial if a time has elapsed since the last addition of a laundry treatment agent that tends to dry, sediment or incre- ment, indicating a change in the state of aggregation. Then, with a first or further rinsing steps, the remainder of the residues of laundry treatment agent would be operated and, with a subsequent rinsing step, only the almost complete rinsing.
  • relevant peculiarities of all the laundry treatment agents used should be stored in the laundry treatment machine and taken into account when deciding on a conditioner and possibly on its character.
  • the relevant peculiarities of laundry treatment agents could be determined from current measurement results and taken into account when deciding on a conditioner and possibly also on its character.
  • the control device could be designed to be adaptive and replace stored peculiarities by measuring results on a younger sample of the same laundry treatment agent.
  • the control device could also select that for the subsequent dosage, which does not react detrimentally with the laundry treatment agent of the previous supply.
  • the method according to the invention can also be improved in such a way that a delivery of a further dose following the delivery of a dose is already carried out at least partially together with the rinsing step or the rinsing steps or parts thereof.
  • a laundry treatment machine may be a washing machine, a laundry dryer or a combination of a washing machine and a tumble dryer.
  • a laundry treatment room 2 is arranged, in which the laundry for the purpose of their treatment can be filled in a manner not shown.
  • This treatment room 2 can stand still and contain a container rotating together with the laundry or turn itself.
  • Within the housing 1 - no matter in which part of its interior - is one or a number of storage containers 3 for different liquid or gel-like (at least flowable) laundry treatment arranged, the contents of which can be given via outlet 4 and dosing 5 in a common dosing 6. From the dosing line 6, the doses of laundry treatment agents are transferred to the laundry treatment room.
  • the highest point of the metering line 6 is a
  • Purge line 7 coupled, which - controlled by a detergent control 8 - can be fed from a detergent source 9.
  • the metering devices 5 and the flushing agent control 8 are signaled by a control device 12 via suitable lines 10 and 11, respectively, so that each of these devices delivers the respective assigned medium at points in time determined by the control device 12.
  • the rinsing agent source 9 may be a storage or intermediate storage container for a certain amount of rinsing agent (preferably water) or a connection device to a fresh water network.
