Abstract

A household dishwasher includes a dishwasher cavity, and a functional region embodied in one piece with the dishwasher cavity and processed by a laser processing method.

First claim

What is claimed is:

1. A household dishwasher, comprising:
a dishwasher cavity; and
a functional region embodied in one piece with the dishwasher cavity and processed by a laser processing method, the functional region comprising:
one or more connections molded onto a wall of the dishwasher cavity to receive an add-on part of the household dishwasher; and
one or more through-holes corresponding to the one or more connections on the dishwasher cavity, the one or more through-holes being provided on a respective connection of the one or more connections integrated with the dishwasher cavity.

2. The household dishwasher of claim 1 , wherein the functional region is a filter area having a perforation and provided on a base of the dishwasher cavity.

3. The household dishwasher of claim 2 , wherein the perforation has openings that pierce through the base and have a respective size which is variable within the perforation.

4. The household dishwasher of claim 3 , wherein the respective size of the openings decreases toward a center of the functional region, starting from an edge of the functional region, to form a size gradient associated with the openings.

5. The household dishwasher of claim 4 , wherein the openings each widen toward the center of the functional region, starting from the edge of the functional region.

6. The household dishwasher of claim 3 , wherein the functional region has at an edge thereof one or more protective perforations of a geometry and size which differ from a geometry and the size of the openings, and wherein the household dishwasher comprises a pump sump positioned to receive a fluid supply via the one or more protective perforations to clean the pump sump.

8. The household dishwasher of claim 7 , wherein the pump sump has a dirt-resistant surface.

9. The household dishwasher of claim 8 , wherein the dirt-resistant surface is hydrophobic, microstructured, plasma-coated and/or nano-coated.

10. The household dishwasher of claim 9 , wherein the dirt-resistant surface comprises one or more projected components positioned on the dirt-resistant surface to modify flow dynamics to provide dirt-resistant properties.

11. The household dishwasher of claim 7 , wherein the pump sump is manufactured from a plastic material filled with nanoparticles.

12. The household dishwasher of claim 1 , wherein the one or more connections are provided on an outside of the dishwasher cavity.

13. The household dishwasher of claim 1 , further comprising the add-on part assembled on at least one of the one or more connections, wherein the add-on part comprises one or more corresponding connections to couple to the one or more connections of the functional region.

14. The household dishwasher of claim 1 , wherein the functional region includes an exhaust vent molded onto the dishwasher cavity.

15. The household dishwasher of claim 1 , wherein the functional region and the dishwasher cavity form a common component such that the functional region is inseparable from the dishwasher cavity.
