  • Patent number: 8182612
    Abstract: A method is provided for the removal from a heat exchange of lint that is generated during a drying process in a domestic appliance for laundry care. A rinsing fluid is run through the heat exchanger for cleaning and the rinsing fluid is deflected during a cleaning phase with the magnitude of deflection or the direction of deflection of the rinsing fluid being a function of the strength of an air flow that is applied to deflect the rinsing fluid. The rinsing fluid is thus run through various regions of the heat exchanger depending on the deflection.

  • Publication number: 20120024801
    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.

  • Publication number: 20120017456
    Abstract: A condensation dryer has a drying chamber for items to be dried, and a process air channel in which a heater for heating the process air and a fan for delivering the process air are located. A rinsing device is provided for rinsing lint from a component that can be loaded with lint, by means of condensate from a condensate collection vessel. Rinsed lint is collected by a filter bag of a filter device, and a condensate pump delivers the condensate into the condensate collection vessel, with the filter device and the being arranged downstream of the component. The filter bag includes a nonwoven fabric.

  • Publication number: 20110167662
    Abstract: A dryer has a drying chamber to receive damp items and a process air duct to feed process air into and extract process air out of the drying chamber. The process air duct has a heat source and a heat sink to heat the process air before the process air enters the drying chamber and to cool the process air after the process air leaves the drying chamber, respectively. A cleaning device has an accumulator for a liquid; a rinsing line connected to the accumulator; a control organ in the rinsing line; a distributor connected to the rinsing line to distribute the liquid conveyed through the rinsing line on a lint filter and to receive the lint caught by the lint filter; and a drain line to drain the liquid with the received lint away from the lint filter and towards the accumulator.

  • Publication number: 20110056523
    Abstract: A method for cleaning a component of a domestic appliance for laundry items. During a cleaning process, a rinsing fluid is at least once conducted through the component. Further, foreign bodies are cleansed from the component. The cleaning process is automatically started and a rinse cycle is performed in which the rinsing fluid is at least once introduced into the component. The rinse cycle is performed after a care process and during a process that prevents creases in the dry laundry items. The dry laundry items are still in the domestic appliance.
