Household appliance for the care of laundry items with a dispensing tray and a suds container

1. A household appliance for the care of laundry items, with a dispensing tray and a laundry container, which is connected to the dispensing tray via at least one supply duct, wherein a water trap vapor barrier is formed in a curved line section in the supply duct, the line section having a first end connected to the dispensing tray and a second end connected to the laundry container, wherein a ventilating channel is formed in the line section and has a ventilating outlet at the first end and connected to the dispensing tray and a ventilation channel inlet that is spaced from the ventilating outlet, wherein a partition wall located at least partially within the supply duct separates the ventilating channel at the first end from a supply channel that comprises the water trap vapor barrier for supplying liquid medium from the dispensing tray to the laundry container via the water trap vapor barrier, wherein, in use, if process air enters the line section from the laundry container, the process air is inhibited from passing through the water trap vapor barrier and is instead channeled into the ventilating channel, thus venting the process air away from the supply channel, and wherein the ventilating channel and the partition wall terminate at the first end.

2. The household appliance as claimed in claim 1 , wherein the first end is an upper end.

3. The household appliance as claimed in claim 1 , wherein the ventilating channel is formed so as to at least partially encircle the supply channel at the first end.

4. The household appliance as claimed in claim 1 , wherein a lower end of the ventilating channel opens into the supply channel at an opening point, wherein the opening point lies above a liquid level forming the water trap vapor barrier in the supply channel.

5. The household appliance as claimed in claim 1 , wherein, downstream of an opening of the ventilating channel, the supply channel comprises a flexible channel section.

6. The household appliance as claimed in claim 5 , wherein the flexible channel section is formed of a corrugated tube.

7. The household appliance as claimed in claim 1 , wherein the supply duct is formed as a one-piece line section.

8. The household appliance as claimed in claim 7 , wherein the one-piece line section comprises an injection molded part.

9. The household appliance as claimed in claim 1 , wherein the household appliance is a washing machine or a washer dryer.

10. The household appliance as claimed in claim 1 , wherein the dispensing tray includes an air vent channel in communication with the ventilating channel.

11. The household appliance as claimed in claim 10 , wherein the air vent channel is formed on an exterior surface of the dispensing tray.

12. The household appliance as claimed in claim 1 , wherein the supply duct includes a mixing line section that extends from the second end of the supply duct to the water trap vapor barrier of the supply duct, wherein the mixing line section is configured to accommodate a mixture of the process air and the liquid medium simultaneously, and wherein the partition wall separates the process air from the liquid medium as the process air moves from the second end of the supply duct to the first end of the supply duct.

13. The household appliance as claimed in claim 1 , wherein the supply duct includes only a single connection to the dispensing tray for both the liquid medium and the process air and only a single connection to the laundry container for both the liquid medium and the process air.

14. A supply duct for connecting a laundry container of a household laundry washing machine or washer/dryer to a detergent dispensing tray, the supply duct comprising:

a line section having a curved portion with a water trap vapor barrier device and a water/detergent supply channel to receive liquid medium from the dispensing tray, the line section having a first end adapted to be connected to the dispensing tray and a second end adapted to be connected to the laundry container;

a ventilating channel formed in the line section, the ventilating channel having an inlet spaced from the first end of the line section, wherein, in use, if process air enters the line section from the laundry container, the process air is inhibited from passing through the water trap vapor barrier device and is instead channeled into the ventilating channel, thus venting the process air away from the water/detergent supply channel;

a partition wall extending to the first end to separate the ventilating channel from the water/detergent supply channel; and

wherein the ventilating channel and the partition wall terminate at the first end.

15. The supply duct as claimed in claim 14 , wherein the first end is an upper end.

16. The supply duct as claimed in claim 14 , wherein the ventilating channel is formed so as to at least partially encircle the supply channel at the first end.

17. The supply duct as claimed in claim 14 , wherein a lower end of the ventilating channel opens into the supply channel at an opening point, wherein the opening point lies above a liquid level forming the water trap vapor barrier device in the supply channel.

18. The supply duct as claimed in claim 14 , wherein, downstream of an opening of the ventilating channel, the supply channel comprises a flexible channel section.

19. The supply duct as claimed in claim 18 , wherein the flexible channel section is formed of a corrugated tube.

20. The supply duct as claimed in claim 14 , wherein the supply duct is formed as a one-piece line section.

21. The supply duct as claimed in claim 20 , wherein the one-piece line section comprises an injection molded part.

22. A household laundry washing machine or washer/dryer comprising the laundry container, the detergent dispensing tray and the supply duct of claim 14 .
