Embodiment Construction

[0059] The washer-dryer shown in the only illustration of the drawing has a lye container 1 and a drum 2 rotatable about a substantially horizontal axis in the lye container, in which the laundry 3 is located. The lye container 1 is connected to the lye pump 12 through the lye discharge pipe 19, and the lye pump can discharge the aqueous liquid 11 from the lye container 1 through the drain pipe 13 to the outside of the washer-dryer. The drum 2 is driven by means of a drive motor 4 .

[0060] The drum 2 is loaded with laundry 3 to be treated through the filling opening 22 . In order to be able to wash laundry in the washer-dryer, the washer-dryer is connected via a water supply system 20 to an external water supply (not shown here). A water supply system 20 is connected to a flushing box 21 from which detergent components or cleaning aid components can be fed into the lye container 1 by means of water from the water supply system 20 . This takes place here via a part of the p...

Abstract

The invention relates to a method for removing odorous substances from laundry items (3) in a clothes dryer, wherein the clothes dryer comprises a suds container (1), a drum (2) that is rotatably mounted in the suds container for receiving laundry items (3), a control device (18), and a process air channel (5) in which a heater (7) for heating air, a blower (6), and a heat exchanger (8) are situated, comprising the steps of: (a) generating a warm air flow in that air is heated by means of the heater (7) in the process air channel (5) and is transported by means of the blower (6); (b) introducing an aqueous liquid (11) via the heat exchanger (8) into the suds container (1) at a quantity that is not sufficient for the drum (2) to be immersed in the aqueous liquid (11); (c) heating the aqueous liquid (11) by bringing same into contact with the warm air flow; (d) generating a water vapor flow (17) by at least partially evaporating the aqueous liquid (11); and (e) bringing the water vapor flow (17) into contact with the laundry items (3). The invention further relates to a clothes dryer suitable for carrying out said method.

Description

technical field [0001] The present invention relates to a method for removing odorous substances from laundry in a washer-dryer and a washer-dryer suitable for the method.
