- a section of the process air duct in which impurities or flakes settle is flooded with a liquid during a cleaning phase for a certain period of time.
- This can be, in particular, a section of the process air duct in which there is a heat exchanger for condensing moisture present in the process air.
- the liquid is removed from the flooded section at the end of the cleaning phase. Due to the interruption of the drying process in the cleaning phase, the entire process of drying the laundry is prolonged and requires additional control and sealing measures.
- a device and a method of the initially mentioned type can be found in the publication DE 10 2007 016 074 A1.
- This describes a device and a method for cleaning a arranged within a process air cycle of a washing and laundry dryer component, in particular an evaporator of a condenser unit.
- condensate separated out of the process cycle is first collected in a condensate water tank, from which it is then pumped to a rinsing tank provided above the evaporator.
- the condensate passes as a flood of water on or to the component to be cleaned.
- the rinse water is lint-laden with condensate.
- FIG. 1 a schematic exemplary sectional view of a tumble dryer 1 is shown in FIG.
- This comprises a drum 2, which can rotate about an axis of rotation extending perpendicular to the plane of the figure and is designed to accommodate items of laundry.
- the loading of the drum 2 takes place via a feed opening 3.
- the tumble dryer 1 comprises a process air guide which is not further specified in the figure, via which process air is conducted into the drying chamber or the drum 2 and absorbs moisture there.
