Abstract (en)
[origin: WO2012028458A1] The invention relates to a method for cleaning a process air channel 5 in a washer/dryer, wherein the washer/dryer has a washing tub 1, a drum 2 which is mounted rotatably in the washing tub 1 for receiving laundry items 3, a control device 18 and the process air channel 5, in which a heater 7 for heating air, a fan 6, a heat exchanger 8 and a transition part 25 between the heat exchanger 8 and the washing tub 1 are situated. The method comprises the following steps: (a) provision of an aqueous liquid 11 in the washing tub 1 and in the transition part 25, with the result that a proportion Qaq of a cross section Qtot of the transition part 25 is taken over by the liquid 11; (b) generation of a process air stream 17 of air which is situated in the process air channel 5, at a flow speed vair, by means of the fan 6; (c) bringing the air flow 17 into contact with the liquid 11 in the washing tub 1 and in the transition part 25, with the result that a mixture of the liquid and the air 15 is formed, wherein the proportion Qaq and the flow speed vair of the process air stream 17 are selected in such a way that the mixture 15 is produced in such a way that it does not take up the cross section Qaw = Qtot - Qaq which is not filled with the liquid 11 in the transition part 25; and (d) cleaning of the process air channel 5 by means of the mixture. Moreover, the invention relates to a washer/dryer which is suitable for carrying out this method.
