the trap is adapted to be filled by liquid from the dispensing shell.
2. The dispensing unit as claimed in claim 1 , wherein
the trap comprises a reservoir including side walls and a lower wall and being divided by an upper partition that extends down into the reservoir and has a lower edge that extends below an upper edge of the lower wall, the upper partition dividing the reservoir into an interior part and an exterior part,
the interior part of the reservoir being opened to the interior of the dispensing shell and being capable of being filled from it,
the exterior part of the reservoir being opened to the overflow, and
the edge of the lower wall lying at least partially below the lower edge of the overflow.
3. The dispensing unit as claimed in claim 1 , wherein the upper partition extends throughout at least 5 mm lower than the lowest point of the upper edge of the lower wall.
4. The dispensing unit as claimed in claim 1 , wherein the interior part and the exterior part of the trap are arranged horizontally with respect to each other in the dispensing shell.
5. The dispensing unit as claimed in claim 1 , wherein the reservoir is integrated in a lower part of the dispensing shell and the upper partition is integrated in an upper part of the dispensing shell.
6. The detergent dispensing unit as claimed in claim 2 , wherein the opening that leads to the exterior is an overflow that diverts fluid to an area outside of the dispensing shell.
7. The detergent dispensing unit as claimed in claim 1 , wherein the opening that leads to the exterior is an overflow that diverts fluid to an area outside of the dispensing shell.
8. The detergent dispensing unit as claimed in claim 7 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
9. The detergent dispensing unit as claimed in claim 2 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
10. The detergent dispensing unit as claimed in claim 1 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
11. A washing machine comprising:
a housing;
a detergent dispensing unit disposed within the housing and including:
a dispensing shell and a dispensing connection permitting the entry of fresh water into the dispensing shell; and
a trap being located fluidly between an interior of the detergent dispensing unit and an opening that leads to the exterior, the opening which leads to the exterior being an overflow,
wherein the trap is positioned in the dispensing shell downstream of which the dispensing connection,
a maximum filled level of the trap lies below a lower edge of the overflow and
the trap is adapted to be filled by liquid from the dispensing shell.
12. The washing machine as claimed in claim 11 , wherein
the trap comprises a reservoir including side walls and a lower wall and being divided by an upper partition that extends down into the reservoir and has a lower edge that extends below an upper edge of the lower wall, the upper partition dividing the reservoir into an interior part and an exterior part,
the interior part of the reservoir being opened to the interior of the dispensing shell and being capable of being filled from it,
the exterior part of the reservoir being opened to the overflow, and
the edge of the lower wall lying at least partially below the lower edge of the overflow.
13. The washing machine as claimed in claim 11 , wherein the upper partition extends throughout at least 5 mm lower than the lowest point on the upper edge of the lower wall.
14. The washing machine as claimed in claim 11 , wherein the interior part and the exterior part of the trap are arranged horizontally with respect to each other in the dispensing shell.
15. The washing machine as claimed in claim 11 , wherein the reservoir is integrated in a lower part of the dispensing shell and the upper partition is integrated in an upper part of the dispensing shell.
16. The washing machine as claimed in claim 12 , wherein the opening that leads to the exterior is an overflow that diverts fluid to an area outside of the dispensing shell.
17. The washing machine as claimed in claim 11 , wherein the opening that leads to the exterior is an overflow that diverts fluid to an area outside of the dispensing shell.
18. The washing machine as claimed in claim 17 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
19. The washing machine as claimed in claim 12 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
20. The washing machine as claimed in claim 11 , wherein the trap provides a water vapor-tight connection between the interior of the detergent dispensing unit and the opening that leads to the exterior.
