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 can be rinsed after supplying a dose by means of a rinsing agent, in particular by means of water.
  • the detergent components in the remaining residues of rinsing solutions can lead to dries, sedimentation or inkrustrationen on conveyors (pumps, valves) and thereby cause disruption of their operation.
  • 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 delayed after the delivery of the dose only in time and is split immediately before supplying the further dose.
  • this time sequence of the flushing of the metering line which is changed in comparison with the prior art, it is possible to prevent nucleation.
  • highly concentrated laundry treatment agent no germs can form.
  • higher concentrated residues of laundry treatment agents which, moreover, are still present in a relatively large amount in the absence of previous dilution, dry out less rapidly than very small amounts of strongly diluted residues. Therefore, the laziness delayed until shortly before the addition of a dose of another laundry treating agent is much more effective in accomplishing the above object than the known rinse following a completed addition of a dose of treating agent.
  • 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. In fact, if the likelihood of reactions between the cans of successive laundry treating agent or a change in state of aggregation makes flushing obsolete, it can be avoided. 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 controller could also select that for the subsequent dosage, which does not react with the laundry treatment agent of the previous supply harmful. Occasionally for individual laundry treatment sections several possible laundry treatment products to choose from, so that may be made by the selection may one that does not respond to the previous reaction.
  • 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 treating machine may be a washing machine, a tumble 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 - one or a number of storage containers 3 for different liquid or gel-like (at least flowable) laundry treatment means arranged, the contents of which can be given via outlet 4 and dosing devices 5 in a common dosing 6. From the dosing line 6, the doses of laundry treatment agents are transferred to the laundry treatment room.
  • a purge line 7 is 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 conveys the respectively assigned medium to 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.
