• This embodiment allows the mixing of concentrated detergent components to increase the yield of active substances such as e.g. Bleaching agent and subsequent dilution to produce an application solution or wash liquor and introducing the application solution into the laundry, since when operating the circulating pump at a speed equal to or greater than the conveying speed located in the tub washing liquid with the operating at the Umflutpumpe at a speed below the Conveying speed generated detergent-component mixture is mixed. Dilution can prevent the laundry from being exposed to a high detergent concentration.
• washing liquid in the form of water is conveyed from the first region of the tub into the second region of the tub by the circulating means in the tub.
• the conveying is preferably stopped when the feed of the at least two detergent components into the circulating pump is started.
