A METHOD FOR ITS REGENERATION This invention is a network used for cleaning items such as laundry or tableware. an ion exchanger that softens the water before sending it to the washing compartment 5 required for preparing the regenerative solution used in resin regeneration making it possible to reduce the number of electrolysis cycles, thus saving energy. a household appliance that provides and ion exchange resin to be used in said household appliance It relates to a method for regeneration. The washing performance of washing and washer-dryer devices in technology is determined by many parameters. It is also affected by the hardness level of the tap water. The ions that cause water hardness... It neutralizes the active ingredients in detergents, reducing washing performance. These ions can also accumulate in the fabric of clothing, causing the colors to fade. This is why. Using hard water causes limescale buildup in different components of the appliance and Therefore, this leads to an increase in energy consumption. This situation affects 15 components. It also shortens their usage times. It provides the desired washing performance in washing systems. To ensure and prolong the lifespan of systems, the use of softened water is important in technology. It is currently a preferred practice. Nowadays, salt is used for regeneration for this purpose. The use of ion exchange resins is common. These systems utilize ion exchange resins and... It consists of two main components: salt and resin. 20% of the water taken from the network passes through the resin. The ions that cause water hardness (Ca+2 / Mg+2) pass through the sodium (Na+) ions present in the resin. It is replaced by a scrubber containing softened water rich in sodium ions. The washing is done by feeding the system. In order for these resins used in technology to retain their water softening properties, the mains water must be treated. Depending on its hardness, at the end of each softening cycle or at 25 seconds as determined by the user / manufacturer. The ion exchange resin is regenerated periodically. With sodium ions. Since calcium and magnesium ions are exchanged, sodium plays a role in resin regeneration. chloride salt is used. In the regeneration step, the resin is supersaturated with sodium chloride. It is washed with a solution. Sodium ions bind to the resin, while calcium-magnesium The ions are passing into the water. Water rich in calcium and magnesium ions is being discharged. 30 The resin, which has transformed into a sodium ion-rich structure, is ready for reuse. 2 is brought in. The supersaturated sodium chloride solution used in the regeneration step. Some of it is eliminated at the end of regeneration. For example, patent EP2988650 (A1) in the known state of the art.

Adapted units for generating saltwater and determining the amounts of water used. These are supported by an electronic control unit that monitors them. However, in systems where regeneration is carried out with salt water, the saline solution used is 15 This necessitates the removal of water from the system. This discharge process affects both the infrastructure. It causes corrosion and also leads to the salinization of soil and water resources. During the loading of salt into the scrubber system for the regeneration step... Spilled and uncleaned salt particles also pose a corrosion risk. Therefore, Alternative arrangements for the regeneration of ion exchange resins in scrubber devices and 20 The need for these methods continues. The aim of this invention is to regenerate ion exchange resin using electrolysis techniques, and by reducing the number of electrolysis cycles required for preparing the regeneration solution an energy-saving household appliance and its control method This allows the ion exchange resin to regenerate with less energy consumption.

Each linear part (34) has an inner diameter, an outer diameter and a length value. It has a cylindrical structure. Ion exchange resin (31), as can be seen from Figure 4, is linear 30 The sections (34) are arranged in such a way that they are filled homogeneously. Here The expression "filled" should be understood as allowing liquid to pass through the linear section (34). 13 The invention is that the amount of ion exchange resin is provided within the linear part (34). In its preferred application, each linear section (34) contains 100 within its evacuated internal volume. 30-100 grams of ion exchange resin per cm3 evacuated internal volume (31) It contains ion exchange resin (31) in a certain proportion.
