At present, II⁺YOUJIA dishwasher adopts German Ecotech economic heating storage and energy saving device in the drying system. It can enhance the washing effect by 30%, the water saving effect reaches 30%-80%. At the same time, it cooperates with the PTC hot air drying system, circulating convection. Full-efficiency drying makes the dishes completely free of residual water; in terms of washing, the equipped new reverse double-layer blade spray arm, micro geometry design water flow nozzle, warped geometry spray arm twisted design, two-speed motor equipped with strong water pressure , 360° clean dishes without dead corners; At the same time, the German Enmet exchange regeneration soften water system was introduced, which increased the cleanliness to 99%, and completely saying goodbye to water stains. The self-developed fresh air system completely solved the concerns of users' placing the dishes for a long time, disinfection, odor and so forth. These continuous breakthroughs and upgrades are all developed by German Dietrich scientific research experts and domestic scientific research teams.
