Abstract
A method for washing laundry and a wash path for laundry in bath change and/or counterflow operation, in which the laundry to be washed when passing through said wash path moves through different treatment zones with chambers 1 to 16, wherein the individual baths are composed of fresh water and waste water of other baths, wherein the waste water of at least one bath without intermediate storage and directly is at least partly supplied to another bath, and wherein no waste water is intermediately stored in the water circulation during washing.
Claims21
A method for washing laundry, in which said laundry to be washed is moved through a wash path with subsequent chambers with different individual baths, wherein said laundry passes at least two of the following zones:
- prewashing zone, clearwashing zone, rinsing zone and aftertreatment zone, and the washing water of the individual baths in the at least two zones includes a variably controlled ratio of fresh water and waste water of other baths,
- wherein said waste water of at least one zone is recovered and at least partly is directly supplied to at least one other zone, and wherein no waste water is stored intermediately in the washing water circulating during washing.
A method for washing laundry, in which said laundry to be washed is moved through a wash path with subsequent chambers with different baths, wherein said laundry passes at least one of the following zones:
- prewashing zone, clearwashing zone, rinsing zone and aftertreatment zone and the washing water of the individual baths is composed of fresh water, or fresh water and waste water of other baths,
- wherein said waste water of at least one zone is recovered and at least partly is directly supplied to at least one other zone, and wherein no waste water is stored intermediately in the water circulation during washing and wherein the water added in a defined area of said wash path is taken from at least two waste water removal positions and is used in a preferably adjustable mixing ratio.
A method for washing laundry, in which said laundry to be washed is moved through a wash path with subsequent chambers with different individual baths, wherein said laundry passes at least two of the following zones:
- prewashing zone, clearwashing zone, rinsing zone and aftertreatment zone, and the washing water of the individual baths in the at least two zones includes a variably controlled ratio of fresh water and waste water of other baths,
- wherein said waste water of at least one zone is recovered and at least partly is directly supplied to at least one other zone, wherein no waste water is stored intermediately in the water circulation during washing, and wherein said waste water is taken from at least one of the beginning of said rinsing zone, the beginning of said aftertreatment zone from a drain means following said wash path.
A wash path for laundry in bath change and/or counterflow operation comprising:
- a wash drum with several subsequent chambers for a plurality of baths in said wash drum,
- a transfer means for transferring said laundry through said wash drum, and
- at least one fresh water supply position and at least one waste water removing and supply position for water removal and water supply,
- wherein said wash path comprises a water recovery system whose water-carrying components exclusively consists of direct lines transferring water between water supply positions and water removal positions without any water storage component and wherein said water supply recovery system comprises water removal positions which permits an exactly defined water removal.
A wash path for laundry in bath change and/or counterflow operation comprising:
- a wash drum with several subsequent chambers for a plurality of baths in said wash drum,
- a transfer means for transferring said laundry through said wash drum, and
- at least on fresh water supply position and at least one waste water removing and supply position for water removal and water supply,
- wherein said wash path comprises a water recovery system whose water-carrying components exclusively consist of direct lines transferring water between water supply positions and water removal positions without any water storage component and wherein said wash path comprises water supply positions which are connected to at least two water removal positions.
A wash path for laundry in bath change and/or counterflow operation comprising:
- a wash drum with several subsequent chambers for a plurality of baths in said wash drum,
- a transfer means for transferring said laundry through said wash drum, and
- at least one fresh water supply position and at least one waste water removing and supply position for water removal and water supply,
- wherein said wash path comprises a water recovery system whose water-carrying components exclusively consist of direct lines transferring water between water supply positions and water removal positions without any water storage component and wherein said water recovery system comprises water removal positions which permit an exactly defined water removal.
A wash path for laundry in bath change and/or counterflow operation comprising:
- a wash drum with several subsequent chambers for a plurality of baths in said wash drum,
- a transfer means for transferring said laundry through said wash drum, and
- at least one fresh water supply position and at least one waste water removing and supply position for water removal and water supply,
- wherein said wash path comprises a water recovery system whose water-carrying components exclusively consist of direct lines transferring water between water supply positions and water removal positions without any water storage component and wherein said wash path comprises at least a pre-washing zone, a clearwashing zone, a rinsing zone and an aftertreatment zone, and wherein said water recovery system comprises water removal positions in at least one of the end of said clearwashing zone, in the end of said rinsing zone, and said aftertreatment zone, which are directly connected to supply positions in at least one of said prewashing zone, clearwashing zone, and rinsing zone through lines.
