Definitions

  • the present invention relates to a washer or washer-dryer comprising a baffle which filters the rinsing water.
  • rinsing step water is sent to the textile products cleaned with detergent in the washing step to remove the detergent. It is known that the detergent remaining on the textile at the end of the rinsing step is harmful for human health. Therefore, a high amount of water is consumed in the rinsing step and multiple rinsing cycles are carried out in order to reduce detergent residues and remove the detergent remaining on the textile surface at the levels set forth by the standards. Moreover, spin-drying is performed for rinsing purposes at high speeds to remove the detergent water on the textile, which causes an increase in energy consumption.
  • a filter unit which is positioned in the body at the lower section of the tube and which comprises a filter produced from a material such as nonwoven fabric, etc. in order to cleanse the dirt and detergent residues in the laundry washing cycle.
  • a washing machine comprising a filter unit which filters foreign particles such as fibers, etc. in order to decrease water consumption in the washing cycle.
  • a washing machine comprising a filter capable of removing foreign matter from water while agitating laundry.
  • the aim of the present invention is the realization of a washer or washer-dryer wherein the rinsing water which gets dirty with residues such as detergent, fibers, textile dyes, etc. remaining on the laundry after the first rinsing step is cleaned to be reused.
  • the washer or washer-dryer of the present invention comprises a baffle which filters the detergent, dye and textile fibers in the rinsing water during the rinsing step.
  • the washer or washer-dryer of the present invention comprises a baffle having at least one nonwoven fabric filter coated with cationic material and/or a cationic polymer filter.
  • the clean water delivered onto the laundry in the first rinsing step is passed through the baffle comprising the filter before the second rinsing step to be cleaned and thus the filtered water can be reused in the rinsing steps.
  • the selected cationic polymer material and/or polymer mixtures are in liquid form according to their molecular weight and the proportion of monomers in the copolymer, and are in a form suitable to be applied/coated to the nonwoven fabric filter or in a hard and rigid form, and can be also used in solid form which is filled into the cylindrical filter body.
  • the filter is detachably placed in a housing in the baffle. In an embodiment of the present invention, the filter can be directly attached into the baffle receptacle.
  • the nonwoven filter coated with cationic polymer material or the cationic polymer ball filter filters the detergent residues, textile dyes, dirt and fibers remaining in the water after the rinsing step so as to enable the water to be cleaned and reused in the rinsing steps.
  • the nonwoven filter in an embodiment of the present invention is produced from biodegradable and recycled materials.
  • a washer or washer-dryer is realized, which performs the washing process with less water and lower number of rinsing steps. Moreover, the amount of dirt in the waste water generated at the end of the washing cycle is reduced.
