From a funnel-shaped detergent container with an outlet opening, which is located above a metering and adding device Detergent in recesses of the addition device arranged circumferentially distributed filled. By rotating this dosing and adding device the filled recesses to an outlet from which they go to the treatment tank flow to.
  • a big problem with such dosing and adding devices for powder detergents is the one that penetrates into the dosing device Moisture, which clumps the detergent and the dosage becomes at least partially inoperable. That is why in WO 93/18701 provided the interior of the detergent container and the leadership of the To constantly charge the metering and adding device with a compressed air stream, and connect a dehumidifier to the compressed air generator.
  • Another problem with adding detergent from a storage room The portioning forms in a dishwasher or in a washing machine the desired amount of detergent.
  • the detergent is portioned in WO 93/18701, already cited above through the recesses in the rotating addition device.
  • EP 0 599 110 A1 discloses a washing machine and dishwasher with an improved one Detergent distributor and a storage container for detergent (Detergent), which contains several doses of such a detergent. These dosing amounts are given to the washing machine in several washing cycles in succession delivered.
