Definitions

  • the present invention relates to a washing machine comprising a filter for filtering the fibers in the washing water.
  • washing machines In washing machines, the laundry is loaded into a drum disposed in a washing tub supplied with detergent-water mixture and is washed in the drum which is rotated. During the washing process, fibers separated from the laundry subjected to both mechanical and chemical effects are discharged, together with the water discharged at the end of the washing process, to the waste water line whereto the washing machine is connected. In traditional washing machines, each washing process causes approximately 1 milligrams of fibers to be discharged to the waste water line. It is determined that more than half of microplastic accumulation in the nature is caused by waste waters originating from washing machines. Especially, taking into account the damage caused by synthetic fibers and particles in the nature, it is observed that waste waters originating from washing machines causes a critical environmental pollution.
  • a washing machine comprising a filter which is positioned under the detergent dispenser.
  • a washing machine comprising a filter which is disposed into the detergent compartment.
  • the aim of the present invention is the realization of a washing machine wherein the cleaning of the filter, which retains the fibers breaking off from the laundry during the laundry washing and/or drying process, is facilitated.
  • the washing machine realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a tub which is disposed in the body; a housing which is in fluid communication with the tub; a circulation line which transfers the water taken from the tub to the housing; a dispenser which is movably placed into the housing; and a filter box which is placed onto the dispenser so as to move together with the dispenser and which comprises at least one filter through which the water coming from the circulation line is passed and which filters the fibers in the water.
  • the filter is a microfilter.
  • the dispenser moves between an open position where the dispenser extends out of the housing and a closed position where the dispenser is almost completely in the housing.
  • the filter box moves together with the dispenser.
  • the washing machine of the present invention further comprises a cleaning member having an arm which is fixed to the housing and a headpiece which is provided on the arm and which scrapes the filter surface while the dispenser is moved with respect to the housing and sweeps the fibers on the filter.
  • the headpiece is fixed.
  • the headpiece is kept fixed so as to contact the filter surface.
  • the headpiece sweeps the fibers on the filter and gathers the same at the rear side of the filter.
  • the user desires to clean the filter, he/she can easily remove the fibers gather at one point from the filter.
  • the arm is detachably fixed onto the housing.
  • the arm can be also dislodged from the housing.
  • the user desires to clean the arm, he/she can dislodge and clean the arm and then fix the same into the housing.
  • the arm is fixed to the housing by means of at least two magnetic members.
  • the magnetic members can be two magnets with opposite poles at the facing surfaces, one being placed onto the arm and the other onto the housing. As the opposite poles face each other, the magnets create an attraction force with respect to each other, and thus the arm is kept fixed on the housing.
  • a magnet is provided on the arm and a ferritic stainless steel is used on the housing. By means of the magnetic members, the position of the arm in the housing is centered.
  • the washing machine comprises the cleaning member wherein the part of the headpiece touching the filter is partially or completely produced from a flexible material The headpiece scrapes the filter as the dispenser is moved. By producing the headpiece from a flexible material, the economic life of the filter is increased.
  • a sweeper which is produced from a flexible material is attached onto the headpiece.
  • the sweeper scrapes the filter as the dispenser is moved, and removes the fibers from the filter surface.
  • the sweeper is preferably produce from rubber material, and is in the form of a rubber band or brush.
  • the sweeper is detachably attached onto the headpiece. Thus, the damaged sweeper can be removed and replaced by the user.
  • the filter box comprises an active carbon filter.
  • the active carbon filter absorbs the microbial residues on the fibers and detergent residues on the carbon surface thereof. Thus, formation of bad odor in the filter box is prevented.
  • the active carbon filter comprises a contact surface wide enough not to affect the filtering rate.
  • the active carbon filter is detachably attached onto the filter box.
  • the active carbon filter which is clogged or not efficiently working can be removed and replaced.
  • the active carbon filter comprises a handle.
  • the active carbon filter can be easily detached from/attached to the filter box.
  • the washing machine comprises a vibration means.
  • the vibration means is disposed between the dispenser and the filter box.
  • the water sent into the filter box is enabled to be vibrated such that the fibers homogeneously spread over the filter surface.
  • the vibration means is activated as the water is sent into the dispenser and is operated during the filtering process.
  • a washing machine having the cleaning member which enables the fibers accumulated on the filter of the filter box to be gathered at a certain point in the box.
  • the user can easily clean the filter.
  • the washing machine (1) comprises a body (2); a tub (3) which is disposed in the body (2); a drum (4) which is disposed in the tub (3) and wherein the washing process is performed; a housing (5) which is arranged on the body (2) and which is in fluid communication with the tub (3); a circulation line (6) which enables the water received from the tub (3) to be delivered to the housing (5); a dispenser (7) which is movably disposed into the housing (4); and a filter box (9) placed into the dispenser (7) so as to move together with the dispenser (7) and having at least one filter (8) through which the water coming from the circulation line (6) and which filters the fibers in the water.
