Definitions

  • the invention relates to a method for wet-treating laundry according to the preamble of claim 1. Furthermore, the invention relates to a device for wet treatment of laundry according to the preamble of claim 10.
  • the method and the device of the type mentioned here relate to so-called continuous washing machines for commercial laundries.
  • Such continuous washing machines such as EP-0 063 476 have a rotating drivable, elongated drum.
  • the laundry is conveyed longitudinally through the drum.
  • the laundry gradually passes through the individual chambers, where it remains in each chamber for a certain time.
  • the chambers form in the drum a prewash zone, a final wash zone and a rinse zone.
  • a post-treatment for example, equipment
  • the pre-wash, clear wash and rinse zones are formed depending on the size and purpose of the continuous washing machine from one or more successive chambers.
  • the invention has for its object to provide a method and apparatus for wet treatment of laundry, which are flexible in terms of the type of laundry to be processed and ensure the greatest possible efficiency.
  • a method for achieving this object comprises the measures of claim 1.
  • the treatment liquid such as rinsing liquid or optionally also aftertreatment liquid
  • the laundry items are thus each rinsed with their own treatment liquid or aftertreated. Due to the invention, the laundry items are always reloaded into virtually empty chambers, in which there is no or almost no treatment liquid, with which the preceding laundry item has been rinsed. It has also been shown that with the same use of fresh water compared with working on the counterflow principle continuous washing a better dishwashing result is achieved because virtually no rinse water is carried into adjacent chambers, resulting in a more favorable dilution ratio and the laundry can be individually rinsed, especially with one adapted to the respective laundry items treatment liquid.
  • At least one bath change is carried out in the rinsing zone serving for rinsing and optionally also for aftertreatment by discharging and supplying treatment liquids.
  • the treatment liquid to be removed is rinsing liquid or aftertreatment liquid.
  • the supplied treatment liquid is usually fresh water.
  • additives can be added to the fresh water, especially in the case of carrying out a post-treatment, for example finishing agents.
  • the rinsing of the respective laundry item takes place in this way with fresh water, without the batch of laundry is mixed with rinse water from the area of another Wäschepostens. It is also conceivable to load the laundry without the treatment liquid not bound therein, the free liquor, into a subsequent chamber. Then immediately fresh water is filled up and before the onward transport of the laundry item into the subsequent chamber, the fresh water contaminated by the rinsing, namely rinsing water, is removed before this item of laundry passes into the next chamber of the rinsing zone which is used for rinsing or, if appropriate, aftertreating.
  • the treatment liquid (after-treatment liquid or rinsing liquid) which can be used for rinsing or finishing is preferably removed and replaced by new treatment liquid, in particular fresh water.
  • new treatment liquid in particular fresh water.
  • each chamber of the continuous washing machine can be loaded with an item of any laundry.
  • the method is provided to make several bath changes during the treatment of the laundry in a chamber.
  • special laundry can be rinsed extremely intensively. It is also possible to rinse the laundry in the same chamber and then post-treat.
  • the laundry can be individually rinsed with more or less fresh water depending on their nature be, and only with as much fresh water, as it is required for each type of laundry.
  • the fresh water requirement can be reduced by the inventive method in this way to a minimum.
  • the rinse zone can then have one or more chambers in which no bath change takes place.
  • the laundry is then transported through the treatment liquid through these chambers without a bath change. Because the purging time in the individual chambers is coupled to the cycle time in the other chambers of the continuous washing machine, decoupling by rinsing can take place in several successive chambers without a bath change.
  • At least one bath change is made at the beginning of the rinsing process in the first chamber of the rinsing zone. In the or each subsequent chamber is then no bath change. Only if the laundry is to be equipped, must at least one bath change be possible in the last chamber of the rinsing zone. It is also possible, by appropriate control of the continuous washing machine all chambers form so that they allow at least one bath change, but do not make at least one bath change in all chambers. Then, a bath change takes place depending on the particular type of laundry to be rinsed, by the controller specified. Likewise, it can be specified individually by the control, in which chamber or in which chambers a multiple bath change is made.
  • the outer drum makes it easy to quickly change the bath. Above all, it allows the stationary outer drum to carry out the bath change while continuing to drive the drum having the chambers. It takes place so when changing the bath at least rudimentary a spin of the laundry instead, in which a part of the bonded liquor pressed out of the laundry and thus can be separated at the bath change together with the free liquor of the laundry.
  • the rinsing zone is formed by a plurality of chambers, wherein only a part of the chambers is associated with an outer drum.
  • An outer drum has only that chamber of the rinsing zone within which at least one bath change takes place or at least one bath change is provided.
  • the remaining chambers, in which no bath change is provided, need not have an outer drum.
  • the part of the drum which is in the area of the rinsing zone is only partially liquid-permeable. In the area of those chambers, which is not assigned to an outer drum, the drum has a liquid-impermeable jacket section. On the other hand, the drum is at least partially liquid-permeable in the area of chambers with outer drums serving for the bath change.
  • the figures show various continuous washing machines for washing, rinsing and optionally finishing (finishing) of any type of laundry, namely clothing, flat linen, floor mats, carpets and the like. Such continuous washing machines are used in commercial laundries.
  • All shown continuous washing machines have an elongate drum 10 which is rotatably driven about a preferably horizontal longitudinal center axis.
  • the drum 10 is divided into individual chambers, which may be the same or different sizes.
  • One or more chambers form different zones, which are arranged consecutively in the longitudinal direction of the drum 10.
  • the rinse zone 14 serves either only for rinsing the laundry or for rinsing and final aftertreatment of the laundry.
  • the post-treatment can be, for example, equipment, bleaching, neutralization and / or starching of the laundry.
  • the five embodiments of the invention shown in the figures differ in the number of chambers of the prewashing zone 12, the final wash zone 13 and the rinse zone 14. Accordingly, the drum 10 of the continuous washing machine is longer with increasing number of chambers.
  • the continuous washing machine leaves the finished laundry through a discharge chute 15 at the outer rear end of the last chamber of the rinsing zone 14, in which optionally takes place the final aftertreatment of the laundry.
  • Some chambers in the drum 10 are so-called outer drums 16 stationary, so stationary and not like the drum 10 rotating assigned.
  • the outer drum 16 always extends below a lower part of certain chambers, namely those chambers to which an outer drum 16 is associated.

  • the outer drums 16 are liquid-tight educated.
  • the chambers are at least partially liquid-permeable in that the jacket section of the drum 10 extending over the region of the respective chamber is liquid-permeable.
  • the shell sections of the drum 10 are formed in the areas of those chambers, which no outer drum 16 is assigned, liquid-impermeable.
