[0001] The present invention relates to a washer or washer-dryer comprising a baffle which
filters the rinsing water.
[0002] Effective use of water resources, which are destroyed due to climate change, global
warming and unconscious water consumption, gradually gains more importance. In washing
machines and washer-dryers which combine washing and drying functions, it is a requirement
in terms of energy efficiency that the cleaning of contaminated textile products is
performed with the least amount of water and in the shortest time possible.
[0003] In the 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.
[0004] In the state of the art Korean Patent Document No.
KR101059910B1, a filter unit is disclosed, 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.
[0005] In the state of the art Patent Application No.
KR20030012679A1, a washing machine is disclosed, comprising a filter unit which filters foreign particles
such as fibers, etc. in order to decrease water consumption in the washing cycle.
In another state of the art Patent Application No.
US2008282747A1, a washing machine is disclosed, comprising a filter capable of removing foreign
matter from water while agitating laundry.
[0006] 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.
[0007] 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.
[0008] 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.
[0009] 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.
[0010] 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.
[0011] The nonwoven filter in an embodiment of the present invention is produced from biodegradable
and recycled materials.
[0012] By means of the present invention, 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.
