A dishwasher includes a dishwasher cavity having a base, a sump below the dishwasher cavity base, a collecting channel that catches liquid leaking over an upper edge of the sump, and a drainage element that drains liquid collected in the collecting channel past an electrical component that is in a region of the sump.
1. A dishwasher comprising:
a dishwasher cavity configured to contain items to be washed by the dishwasher, the dishwasher cavity having a base;
a sump adjacent to and below the dishwasher cavity base, the sump having a perimeter and an upper outer edge located at the perimeter;
a collecting channel located external to the sump, the collecting channel configured to catch liquid leaking over the upper outer edge of the sump; and
a drainage element in the collecting channel that drains liquid collected in the collecting channel to a location external to the sump and past an electrical component that is external to the sump,
wherein the collecting channel is located adjacent to the upper outer edge of the sump.
2. The dishwasher of claim 1 , wherein the collecting channel has two ends and is open at one of the two ends.
3. The dishwasher of claim 2 , wherein the drainage element is offset with respect to the ends of the collecting channel.
4. The dishwasher of claim 2 , wherein the drainage element is approximately centrally positioned between the two ends of the collecting channel.
5. The dishwasher of claim 1 , wherein the drainage element comprises a liquid outlet opening in the collecting channel.
6. The dishwasher of claim 5 , wherein the liquid outlet opening opens into a hollow cylindrical drip-off connector.
7. The dishwasher of claim 6 , wherein the drip-off connector comprises a deflection edge on its drip-off side.
8. The dishwasher of claim 7 , wherein the deflection edge tapers.
9. The dishwasher of claim 1 , wherein the drainage element has a drainage rib for guiding leaking liquid.
10. The dishwasher of claim 9 , wherein a deflection edge of a drip-off connector passes into a rib edge of the drainage rib.
11. The dishwasher of claim 1 , wherein the drainage element has a predetermined drip-off point.
12. The dishwasher of claim 1 , wherein the drainage element guides leaking liquid to a liquid detection facility.
13. The dishwasher of claim 1 , wherein the collecting channel extends around a portion of the perimeter of the sump that is no more than half of an entire length of the perimeter.
14. The dishwasher of claim 1 , wherein the collecting channel extends around a portion of the upper outer edge of the sump and has a shape that conforms to a shape of the upper outer edge of the sump.
15. The dishwasher of claim 14 , wherein the shape of the upper outer edge of the sump is circular and the shape of the collecting channel is a geometric circular arc.
16. The dishwasher of claim 14 , wherein the collecting channel has a bottom that is substantially parallel to and below the upper outer edge of the sump.
17. The dishwasher of claim 1 , wherein the collecting channel has a bottom that is substantially parallel to and below the upper outer edge of the sump.
18. A dishwasher comprising:
a dishwasher cavity configured to contain items to be washed by the dishwasher, the dishwasher cavity having a base;
a sump located adjacent to and below the base, the sump having a perimeter;
a flange attached to the sump, the flange extending completely around the perimeter of the sump, the flange having a flange perimeter;
a collecting channel adjacent to the flange perimeter and configured to catch liquid that leaks over the flange at the flange perimeter, the collecting channel having two ends and extending around a portion of the flange perimeter that is less than the entire flange perimeter;
an electrical component located below the collecting channel and between the two ends of the collecting channel; and
a drainage element configured to drain the liquid caught in the collecting channel such that the liquid avoids contact with the electrical component,
wherein the flange is located adjacent to an upper outer edge of the sump.
19. The dishwasher of claim 18 , wherein the collecting channel extends around a portion of the flange perimeter that is no more than half of the entire flange perimeter.
20. The dishwasher of claim 18 , wherein the collecting channel is open at one of the two ends.
21. The dishwasher of claim 20 , wherein the drainage element is offset with respect to the two ends of the collecting channel.
22. The dishwasher of claim 18 , wherein the drainage element has a drainage rib for guiding the liquid.
23. The dishwasher of claim 22 , wherein the drainage element has a predetermined drip-off point that guides the liquid to the drainage rib.
24. The dishwasher of claim 18 , wherein the collecting channel extends around a portion of the upper outer edge of the sump and has a shape that conforms to a shape of the upper outer edge of the sump.
25. The dishwasher of claim 24 , wherein the shape of the upper outer edge of the sump is circular and the shape of the collecting channel is a geometric circular arc.
26. The dishwasher of claim 24 , wherein the collecting channel has a bottom that is substantially parallel to and below the flange.
27. The dishwasher of claim 18 , wherein the collecting channel has a bottom that is substantially parallel to and below the flange.
