Definitions

  • the present invention relates to a washing machine wherein the fibers from the laundry washed are collected.
  • the water from the mains passes through the detergent box to be transferred to the tub and the drum rotating therein such that the washing process is performed.
  • mechanical effects arising from the rotation of the drum and rubbing with water, effects of the spin-drying, type of fabric, temperature and amount of load, wearing down of the fabric by the detergent used cause the fibers to break off from the laundry.
  • Fibers breaking off from the fabric during the main washing, rinsing and spin-drying steps are delivered from the tub together with the washing water to the discharge hose by means of the discharge pump. Consequently, the fibers breaking off from the laundry are released to the sewer system, underground waters and oceans.
  • Said fibers which are generally synthetic are called microplastics. Microplastics are released into the environment and enter into the food change, thus threatening the lives of living beings.
  • the pump filter Due to the size of the pore openings the pump filter is insufficient in separating these waster materials. When the pore dimensions of the pump filter are reduced in order to retain the micro or millimetric fibers, the filter may get clogged, causing the failure of the pumping process or the disruption of the program flow.
  • Korean Patent Document No. KR20010040355 it is disclosed that the washing water is passed through a hydrocyclone and that the fibers collected are discharged together with the discharge water at the end of the program.
  • the aim of the present invention is to separate the fibers to be discharged with the discharge water from the discharge water, thus preventing the microplastic fibers from being released into the environment.
  • the washing machine realized in order to attain the aim of the present invention, explicated in independent claim 1 and dependent claims 2-5 comprises a hydrocyclone and a filtration hybrid system.
  • the fibers breaking off during the washing process are passed through the hydrocyclone to be separated from the discharge water, and then the cleaned water is discharged.
  • the fibers separated from the discharge water are transferred to the microfilter structure positioned behind the detergent box together with the water remaining in the tub by means of the circulation system at the end of the pumping process duration. While the fibers are retained by said filter structure, the cleaned water is delivered to the tub and discharged. breaking off during the washing process are passed through the hydrocyclone to be separated from the discharge water, and then the cleaned water is discharged.
  • the fibers separated from the discharge water are transferred to the microfilter structure positioned behind the detergent box together with the water remaining in the tub by means of the circulation system at the end of the pumping process duration. While the fibers are retained by said filter structure, the cleaned water is delivered to the tub and discharged.
  • the washing machine comprises
  • the discharge pump comprises a discharge filter which can be accessed from the front wall.
  • the water from the mains is mixed with detergent in the detergent dispenser and then delivered to the tub.
  • the water to be discharged is passed through the discharge pump and then delivered to the hydrocyclone to be cleaned.
  • the discharge valve is open while the circulation valve is closed.
  • the cleaned water is directed to the discharge outlet from the upper part of the hydrocyclone as a result of the centrifugal movement generated due to the geometry of the latter, and then is discharged. At this time, particles in the water hit the walls of the hydrocyclone to be collected in the collection chamber.
  • the discharge valve is closed while the circulation valve is open.
  • the particles collected in the collection chamber are passed together with the water remaining inside through the microfilter cartridge positioned behind the detergent dispenser, and the particles are collected in said cartridge.
  • said microfilter cartridge can be removed together with the detergent dispenser.
  • the pumping duration can be adjusted as the two-thirds of the total pumping duration while the circulation and fiber collection duration can be adjusted as the one-third of the total pumping duration.
  • the microfilter is fixed at the rear side of the detergent dispenser. The user cannot see the filter while adding detergent; however, the filter can be cleaned when the dispenser is removed.
  • fibers can be collected by circulation at once after the last pumping step before the end of the program.
  • a special fiber collection program can be activated by pushing a function button.
  • microplastic fibers which are generally released into the environment with the discharge water are separated from the discharge water. When not filtered, said fibers are released into the sewer system and the oceans and swallowed by the fish. This causes the fish to move more slowly and to be more easily hunted by other fish, thus disrupting the food chain. Moreover, said fibers mix into the table salt and then are ingested by humans, causing health risks. By means of the present invention, the fibers collected in the washing machine are not released into the environment.

Claims (5)

  1. Une machine à laver comprenant une boîte à détergent avec un distributeur de détergent, une baignoire dans laquelle le processus de lavage est effectué, un tambour qui est disposé dans la baignoire et dans lequel le linge à laver est placé, une pompe de décharge et une sortie de décharge pour décharger l'eau à l'intérieur de la baignoire, une soupape de décharge, une vanne de circulation caractérisée par un hydrocyclone disposé sur la ligne d'évacuation pour séparer de l'eau d'évacuation les fibres qui se détachent pendant le processus de lavage et une cartouche de microfiltre disposée à l'arrière de la boîte à détergent et dans laquelle les fibres séparées de l'eau d'évacuation sont transférées avec l'eau restant dans la baignoire au moyen du système de circulation à la fin de la durée d'un processus de pompage, de sorte que les fibres sont retenues par ladite structure filtrante de la cartouche de microfiltre et que l'eau nettoyée est acheminée vers la baignoire et évacuée.
  2. Une machine à laver selon la déclaration 1, caractérisée par l'hydrocyclone qui permet de filtrer les eaux usées évacuées par la pompe de refoulement lorsque la vanne de refoulement est ouverte, et par une chambre de collecte reliée à l'hydrocyclone pour recueillir les fibres et les particules de déchets.
  3. Une machine à laver selon la déclaration 2, caractérisée par la pompe de décharge qui fait circuler l'eau nécessaire à la collecte des fibres et des déchets recueillis dans la chambre de collecte, et par une vanne de circulation qui ferme la vanne de décharge et ouvre la conduite de circulation pour l'exécution du processus de circulation.
  4. Une machine à laver selon l'une quelconque des déclarations précédentes, caractérisée par le fait que pendant les deux tiers de la durée du processus de décharge, la vanne de décharge est ouverte et la vanne de circulation est fermée.
  5. Une machine à laver telle que décrite dans l'une quelconque des déclarations ci-dessus, caractérisée par le fait que pendant le tiers de la durée du processus de décharge, la vanne de décharge est fermée et la vanne de circulation est ouverte, de sorte que le processus de circulation est effectué.
