Description

  • The present invention relates to a washing machine comprising a filter for filtering the fibers in the washing water.
  • 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. Therefore, the use of filters which filter the washing water is becoming widespread. The filters remove the microplastics or fibers in the washing water from the washing water. However, after a certain time, as the processes are repeated, the filters wear out and become unusable. The parts of the filters which contact the washing water the most wear out more quickly compared to other surfaces.
  • In the state of the art Korean Patent Application No. KR20070063996 , a washing machine is disclosed, comprising a filter which is positioned under the detergent dispenser.
  • In the state of the art Chinese Patent Application No. CN201172752 , a washing machine is disclosed, comprising a filter which is disposed into the detergent compartment.

  • 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 placed into the housing, and a filter box provided on the dispenser and having a water inlet opening connected to the circulation line and at least one filter for filtering the fibers in the water. The filter is a microfilter.
  • The washing machine of the present invention comprises a channel which is arranged in the filter box, which is connected to the water inlet and through which the water coming from the circulation line flows, and distribution openings which enable the water flowing through the channel to be delivered onto the filter. The distribution openings are arranged on the channel at certain intervals. The water is sent onto different points of the filter surface through each distribution opening. Thus, the water is delivered onto the filter in a homogeneous manner. Consequently, the risk of a part of the filter being subjected to more water and fibers than other parts so as to be worn down is eliminated. The economic life of the filter is extended.
  • In an embodiment of the present invention, the channel is in the form of a cylindrical tube. Thus, the water flows more easily in the channel.
  • In another embodiment of the present invention, the filter box comprises a fixing member which bears against the channel so as to prevent the channel from moving in the filter box or from dislodging. There can be more than one fixing member in the filter box. Thus, if one of the fixing members is damaged, the channel is kept fixed in the filter box by means of the other fixing members.
  • In another embodiment of the present invention, the washing machine comprises a headpiece which is attached onto the channel. The headpiece is attached onto the end of the channel which is connected to the water inlet opening and enables the channel to be fixed to the water inlet opening. The headpiece is snap-fittingly attached onto the skirt of the water inlet opening which extends into the filter box. In a preferred version of the embodiment, the headpiece is circular. The diameter of the headpiece is larger than the diameter of the water inlet opening. Thus, the fixing of the channel to the water inlet opening is facilitated.
  • In an embodiment of the present invention, the channel is attached to the water inlet opening in an inclined manner. The channel extends from the water inlet opening towards the base of the filter box. Thus, the flow rate of the water taken into the channel is increased. The water is enabled to be sent from the distribution openings onto the filter with more pressure.
  • By means of the present invention, a washing machine is realized, wherein the water sent onto the filter is homogeneously distributed into the filter. Thus, the risk of a part of the filter being more worn down than other parts is eliminated, increasing the economic life thereof.
