  • Patent number: 9447535
    Abstract: A cleaning diffuser is disposed above a fluff-laden component and receives rinsing fluid for distributing the rinsing fluid to the fluff-laden component to detach fluff and carry it away. The diffuser is constructed to enable a buildup of dynamic pressure in the rinsing fluid and has two feed ducts which extend at a distance from one another in substantially parallel relationship so that rinsing fluid entering the diffuser is divided between the feed ducts. The feed ducts terminate in pockets in a wall at an end of the diffuser and have, relative to their entire duct length, a narrow, three-dimensional transverse mutual connection in the form of a transverse chamber. The diffuser has at least one narrow outlet opening which extends from the three-dimensional transverse connection to a lower side of the diffuser for distributing the rinsing fluid to the fluff-laden component.

  • Patent number: 8863401
    Abstract: A household laundry dryer has at least one filter container which includes a chamber with an inlet for condensate water to be cleaned. The chamber has a first outlet, a second outlet and a filter element which is arranged between the inlet and the first outlet and which divides the chamber into an inlet-side first chamber part and a second chamber part. The filter container can be configured in such a way that the inlet is arranged below the filter element and the filter element is arranged below the first outlet, and the second outlet opens into the first chamber part. Particles deposited on the filter element by water being pushed through the inlet into the chamber are detachable from the filter element by water flowing back into the chamber, when no water is being pushed through the inlet, and removable through the second outlet.
