A device is provided for filtering particles from a dishwashing fluid in a dishwashing machine, the dishwashing machine having a dishwashing container in which are disposed items to be subjected to the application of a dishwashing liquid thereto such that particles disentrained from the items during the application of a dishwashing liquid are entrained with the dishwashing liquid. The device includes a container operable to retain therein a predetermined quantity of a liquid mixed with at least one of a foam-forming substance and cleaning agents, the container including an arrangement for producing a flow of a gaseous fluid through the predetermined quantity of the liquid so as to generate a foam layer. The foam layer filters out from a dishwashing liquid passed through the foam layer a substantial fraction of particles entrained with the dishwashing liquid and such filtered-out particles are retained in the foam layer.

Device and method for filtering particles from a liquid in a dishwasher

A dishwasher is provided having a dishwashing container and a filter system for cleaning dishwashing liquid. The filter system includes a foam volume and the filter system and the dishwashing container are communicated with one another such that at least some of the dishwashing liquid can be discharged from the dishwashing container in association with a washing cycle of the dishwashing machine to the foam volume for passage of the discharged dishwashing liquid through the foam volume. Dishwashing residue contained in the dishwashing liquid is at least partially absorbed or retained by the foam volume such that the fine-grained dirt particles can be filtered out of the dishwashing fluid, a resoiling of the dishwashing fluid or the items to be cleaned can be minimized and the dishwashing result can be improved.
