Abstract

A water-conducting domestic appliance including a line system, a detergent feed facility that supplies at least one detergent into the line system, wherein the detergent feed facility includes at least one reservoir configured to be filled with detergent, and a refill fitting having a connection to the at least one reservoir, the refill fitting being arranged on a door of the water-conducting domestic appliance.

Claims (49)

1. A water-conducting domestic appliance comprising:

a washing chamber;

a door to open or close the washing chamber;

a floor pan underneath the washing chamber;

a line system;

a detergent feed facility that supplies at least one detergent into the line system, wherein the detergent feed facility includes at least one reservoir configured to be filled with detergent, and wherein the detergent feed facility is arranged in the floor pan underneath the washing chamber; and

a refill fitting having a connection to the at least one reservoir, the refill fitting being arranged on the door of the water-conducting domestic appliance.

2. The water-conducting domestic appliance as claimed in claim 1 , wherein the refill fitting is arranged so as to be only accessible to an operator when the door is opened.

3. The water-conducting domestic appliance as claimed in claim 2 , wherein the refill fitting is arranged on an inner side of the door.

4. The water-conducting domestic appliance as claimed in claim 2 , wherein the refill fitting is arranged on an upper edge of the door.

5. The water-conducting domestic appliance as claimed in claim 2 , wherein the water-conducting domestic appliance is a domestic dishwasher.

6. The water-conducting domestic appliance as claimed in claim 1 , comprising:

a circulation pump having a connection to the detergent feed facility.

7. The water-conducting domestic appliance as claimed in claim 6 , comprising:

load detection means for detection of load fluctuations of the circulation pump.

8. The water-conducting domestic appliance as claimed in claim 1 , comprising:

a conductivity sensor for detecting a conductivity of washing liquor in the water-conducting domestic appliance.

9. The water-conducting domestic appliance as claimed in claim 1 , wherein the detergent feed facility includes pumping means for introducing at least one detergent.

10. The water-conducting domestic appliance as claimed in claim 1 , wherein the detergent feed facility has at least one dosing chamber.

11. The water-conducting domestic appliance as claimed in claim 1 , wherein the detergent feed facility is configured to empty automatically by force of gravity.

12. The water-conducting domestic appliance as claimed in claim 1 , comprising:

a refill element for filling the detergent feed facility.

13. The water-conducting domestic appliance as claimed in claim 12 , wherein the refill fitting corresponds to a connection of the refill element.

14. A water-conducting domestic appliance comprising:

a wash area including a crockery basket for retaining crockery to be washed;

a door for accessing the wash area;

a line system for supplying washing liquor to the crockery to be washed; and

a detergent feed facility in a floor pan of the wash area that supplies at least one detergent into the line system,

wherein the detergent feed facility includes at least one reservoir configured to be filled with detergent, and

wherein the door includes a refill fitting that is coupled to the at least one reservoir.

15. The water-conducting domestic appliance as claimed in claim 14 , wherein the water-conducting domestic appliance is a domestic dishwasher.

16. The water-conducting domestic appliance as claimed in claim 14 , wherein the refill fitting only is accessible to an operator when the door is in an open position.

17. The water-conducting domestic appliance as claimed in claim 14 , wherein the refill fitting is on an inner side of the door facing the wash area.

18. The water-conducting domestic appliance as claimed in claim 14 , wherein the refill fitting is on an upper edge of the door.

19. The water-conducting domestic appliance as claimed in claim 14 , comprising:

a refill element coupled to the refill fitting for filling the detergent feed facility.

20. The water-conducting domestic appliance as claimed in claim 14 , wherein the door includes at least one line connecting the refill fitting to the at least one reservoir.

21. The water-conducting domestic appliance as claimed in claim 20 , wherein the at least one reservoir includes a plurality of chambers,

wherein the at least one line includes a plurality of separate channels connecting the refill fitting to the plurality of chambers.

22. The water-conducting domestic appliance as claimed in claim 21 , wherein one of the plurality of separate channels includes one of a hose and an extruded profile.

23. A water-conducting domestic appliance, comprising:

a door to a wash chamber;

a refill fitting disposed on a surface of the door;

a line system;

a detergent feed facility with at least one reservoir in a floor pan of the wash chamber;

at least one dosing chamber; and

a circulation pump downstream of the at least one dosing chamber;

wherein the refill fitting, the line system, and the at least one reservoir are configured to deliver at least one detergent from the refill fitting, through the line system, and to the at least one reservoir via gravity; and further

wherein the at least one reservoir is configured to deliver the at least one detergent to the at least one dosing chamber for mixture with rinsing water to create washing liquor that is delivered by the circulation pump to the wash chamber.
