Cartridge for a water-conducting domestic appliance comprising a detergent dosing system

1. A cartridge for a water-conducting domestic appliance, which has a detergent dosing system having at least one detergent dispenser for removably receiving at least one cartridge, wherein the cartridge has at least two chambers for storing at least two detergents, the cartridge comprising:

a cartridge housing having the at least two chambers formed therein, wherein each chamber of the least two chambers has a storage capacity for storing detergent which is greater than a quantity required for one washing cycle, and

wherein each chamber of the at least two chambers includes an openable closure for detergent delivery, the openable closure including means for opening automatically upon insertion of the cartridge into the detergent dosing system and for closing automatically upon removal of the cartridge from the detergent dosing system,

a common cover covering the at least two chambers, the common cover including a ventilation channel in the cover extending across the at least two chambers, and

a ventilation chamber disposed in the cartridge housing between two of the at least two chambers, the ventilation chamber being connected with the at least two chambers via the ventilation channel, wherein the ventilation chamber is without an openable closure.

2. The cartridge according to claim 1 wherein the storage capacity is for between about 20 and about 40 washing cycles.

3. The cartridge according to claim 1 wherein the cartridge is formed with the at least two chambers separated from one another for storing more than about 2 detergents and less than about 10 detergents.

4. The cartridge according to claim 1 wherein the openable closure is formed by a membrane.

5. The cartridge according to claim 1 comprising at least one delivery device configured for delivering the at least two detergents into a washing compartment of the water-conducting domestic appliance.

6. The cartridge according to claim 1 wherein the cartridge is structured to be oriented in the detergent dispenser such that delivery of the at least two detergents takes place by the force of gravity.

7. The cartridge according to claim 1 wherein the cartridge housing includes a mechanical coding configured for interaction with a matching coding on a receiving side for defining an installation position in the water-conducting domestic appliance.

8. The cartridge according to claim 1 wherein the cartridge housing is formed with a longitudinal extension along a main axis of the cartridge housing.

9. The cartridge according to claim 8 wherein the main axis of the cartridge housing is longer than secondary axes of the cartridge housing.

10. The cartridge according to claim 8 wherein the at least two chambers of the cartridge are arranged beside one another along the main axis of the cartridge housing.

11. The cartridge according to claim 8 wherein the extension along the main axis of the cartridge housing is greater by a factor of at least about 1.5 than an extension along a secondary axis of the cartridge housing.

12. The cartridge according to claim 11 wherein an extension along a first secondary axis of the cartridge housing is greater by a factor of at least about 3 than the extension along a second secondary axis of the cartridge housing.

13. The cartridge according to claim 1 , wherein a section of the cartridge facing a washing compartment of the water-conducting domestic appliance comprises thermal insulation that limits heat flow from the washing compartment toward the detergent dosing system.

14. The cartridge according to claim 13 , wherein the thermal insulation comprises a gas volume arranged in said section of the cartridge.
