Definitions

  • the invention relates to a method according to the preamble of the main claim for washing laundry in a countercurrent continuous washing machine.
  • a countercurrent continuous washing machine usually consists of a plurality of chambers arranged one behind the other for treating the laundry.
  • the items of laundry in the compartments are treated by moving them in the wash liquor and are cyclically transported to the next compartment.
  • the length of the drum is divided into several treatment areas, namely generally one or two prewash areas, a rinse area and a rinse area, each of which comprises one or more chambers.
  • the transport from one chamber to the next is generally carried out by a screw or helix, which also forms the division of the chambers.
  • a full rotation of the screw causes a transport step.
  • This transport the largest part of the wash liquor is in the the laundry lot is transferred to the next chamber.
  • This transport of the washing liquor is irrelevant within a treatment area, since the liquor is conveyed from chamber to chamber anyway because of the countercurrent principle, in fact contrary to the transport direction of the laundry.
  • the liquor carried along by the laundry thus runs back into the previous chamber in the course of the further treatment.
  • the invention is therefore based on the object of reducing the water consumption in a method mentioned at the outset in a structurally simple manner and improving the efficiency of the continuous washing machine used.
  • washing liquor is taken from the rinsing area into the first chamber of the rinsing area, but partially drained off before the rinsing treatment, so that the entire liquor no longer has to be rinsed out by adding fresh water.
  • the drained liquor can be returned to the treatment area from which it was taken, or it can be drained into a separate container and used or disposed of in another suitable manner.
  • the drain operation is not carried out in the first chamber of the washing area, but rather already in the last chamber of the washing area, or is additionally provided so that less washing liquid already reaches the washing area here.
  • the drums of a countercurrent continuous washing machine shown in FIGS. 1 to 4 are divided into several chambers which form different treatment areas, namely a prewash area 1, a rinse area 2 and a rinse area 3.
  • the individual items of laundry are moved in the chambers by a back and forth Turning the laundry drum back and forth about 1/2 to 1 turn, the item of laundry remaining in the respective chamber and being flushed through by the liquor.
  • the item of laundry is transported from left to right in the next chamber in the drawing by the drum making an additional full revolution.
  • the respective liquor is moved in countercurrent, ie from right to left in the drawing.
  • the rinse water is fed into the chamber designated c at 4 and discharged at 5 through an overflow at the chamber b.
  • the wash liquor is supplied at 6 into the last chamber a of the final wash area and is discharged through an overflow at 7.
  • the method according to the invention is explained at the transition from the last chamber a of the final washing area 2 to the first chamber b of the rinsing area 3. It can also be carried out in the same way at the transition from the prewash area to the final wash area.
  • the washing drum is a single-walled drum with a closed jacket.
  • a valve 8 is arranged in the drum jacket. After the laundry item located in the chamber a of the rinsing area has been transported into the chamber b of the washing area, which is usually done by a full rotation of the drum, the drum may be stopped in a position in which the valve 8 is in the lowest position Position. The valve 8 then drains most of the wash liquor taken into chamber b.
  • the remaining portion of the washing liquor taken along is rinsed out in a known manner in the chambers b, c via the overflow 5 by the rinse water subsequently supplied.
  • the washing drum shown in FIG. 2 has a fixed outer drum in the area of the first chambers of the final washing and rinsing areas 2, 3.
  • the inner drum is designed with a perforated jacket 9, 10.
  • the associated outer drums 11 and 12 have a closed outer wall with a valve 13, 14 arranged at the lowest point.
  • the one running into the outer drum 12 becomes entrained wash liquor drained through the valve 14 while the flushing begins in countercurrent. This can be done while the machine is running.
  • the washing drum according to FIG. 3 is designed as a double drum with a double jacket which is continuous over the wash and rinse area.
  • Bypass lines 15 are attached to the fixed outer jacket, through which the liquor is passed from chamber to chamber in counterflow to the transport direction of the laundry.
  • Valves 13, 14 are again provided instead of the bypass lines on the first chambers of the clear-washing and rinsing areas 2, 3, through which valves the carried-away washing liquor can be discharged in the manner described.
  • a modification of the method according to the invention is that the liquor is not only discharged after the laundry item has been transported to the next treatment area, but also at the end of the treatment carried out after the liquor has been transported and drained. With this e.g. the consumption of the water required for the rinsing process can be further reduced.
  • a drain valve 21 is provided at the end of the washing area 2.
  • the drain valve 21 can be opened and the liquor located in chamber a can be at least partially drained.
  • the laundry item is now transported into the washing area 3, as described above.
  • the laundry item is then washed in the first chamber b of the washing area.
  • a second drain valve (not shown here) can be provided in order to drain rinsing water which has been contaminated by the liquor residues left behind with the laundry items.
  • the last-described embodiment of the invention ensures a significant reduction in the amount of washing water required, since the laundry is already transported into the first chamber of the washing area with a smaller amount of washing water.
