Dishwasher

1. A dishwasher comprising:

a washing container with a washing chamber;

a water feed line for filling the washing chamber with liquid; and

a water inlet device connected on an inlet side to the water feed line and on an outlet side to the washing chamber, the water inlet device including:

a housing;

ventilation opening in the housing that equalizes a pressure if a negative pressure occurs in the water feed line;

a feed conduit in fluid communication with the water feed line for directing water into the housing, wherein the feed conduit projects into the ventilation opening, and wherein the ventilation opening has free space between the feed conduit and an edge of the ventilation opening whereby the ventilation opening serves as a water inlet opening;

a washing container opening in fluid communication with the water feed line for introducing liquid into the washing chamber for filling the washing chamber with liquid to an operational level and for venting steam from the washing chamber;

a steam outlet opening in fluid communication with the washing container opening for passing steam out of the washing chamber;

a partition within the housing forming a steam duct defining a vertical unobstructed linear path between the washer container opening and the steam outlet opening that guides steam to the steam outlet opening;

and

an expansion line in fluid communication with the steam outlet opening and extending vertically upwardly from the water inlet device for a predetermined distance thereby defining a condensation route along which steam passed out of the washing chamber can condense and fall back into the water inlet device for return to the washing chamber.

2. The dishwasher of claim 1 , wherein the steam duct defines a water inlet chamber and a steam outlet chamber.

3. The dishwasher of claim 2 , wherein the water inlet chamber is connected to the water feed line.

4. The dishwasher of claim 2 , wherein the steam outlet chamber is connected to the steam outlet opening.

5. The dishwasher of claim 4 , wherein the water inlet device defines a connection opening between the steam outlet chamber and the water inlet chamber.

6. The dishwasher of claim 2 , wherein the water inlet device defines a container opening that connects the steam outlet chamber and the washing chamber of the washing container.

7. The dishwasher of claim 1 , wherein the partition defines a water inlet chamber in fluid communication with the water feed line, and a steam outlet chamber in fluid communication with the wash chamber; and a connection opening for passing water from the water chamber to the steam chamber, the connection opening between the water inlet chamber and the steam outlet chamber is smaller than the steam outlet opening.

8. The dishwasher of claim 1 , wherein the partition has a curved section.

9. The dishwasher of claim 1 , wherein at least one of the ventilation opening and the steam outlet opening is on a top side of the housing.

10. The dishwasher of claim 1 , further comprising a cover extending over the ventilation opening, the cover being open on a side for ventilation.

11. The dishwasher of claim 1 , further comprising a retaining element externally on the water inlet device for retaining liquid lines.

12. The dishwasher of claim 7 wherein the water inlet chamber is tapered, whereby the water inlet chamber is reduced in cross-section between the water feed conduit and the connection opening.

13. The dishwasher of claim 1 the housing includes an internal cavity and an internal partition defining a water inlet chamber in fluid communication with the water feed line, and a steam outlet chamber in fluid communication with the wash chamber; and a connection opening for passing water from the water chamber to the steam chamber, the connection opening having a first vertical extent; and wherein the washing container opening has a second vertical extent, and wherein the washing container opening has a portion extending vertically beyond a verticalmost extent of the connection opening.
