Title
(DE) METHOD FOR OPERATING A WASHER-DRYER
(EN) METHOD FOR OPERATING A WASHER-DRYER
(FR) PROCÉDÉ POUR FAIRE FONCTIONNER UN LAVE-LINGE SÉCHANT
Abstract
(EN) A domestic laundry dryer, in particular a washer-dryer, comprises a cabinet (10), a drum (10), and an air circulation system (2, 20, 24, 25, 41; 51). The drum (10) is rotatably placed within a tub (11) and has an opening (16) on a front side for loading laundry. A heat pump (8) is provided with a condenser (21) and an evaporator (22) for drying and heating process air. A ventilator (20) is configured to circulate air in the air circulation system (2, 20, 24, 25, 41; 51). A water trough (4) and a water duct (41) guide water from the evaporator (22) and condenser (21) to the tub (11). The condenser (21) and the evaporator (22) are arranged on a back side of the drum (10). The evaporator (22) is located below the condenser (21). For drying laundry, air is guided along a down-up direction through the evaporator (22) and then the condenser (21).
(FR) L'invention concerne un sèche-linge domestique, en particulier un lave-linge séchant, comprenant une armoire (10), un tambour (10), et un système de circulation d'air (2, 20, 24, 25, 41 ; 51). Le tambour (10) est placé de manière rotative à l'intérieur d'une cuve (11) et a une ouverture (16) sur un côté avant pour charger le linge. Une pompe à chaleur (8) est pourvue d'un condenseur (21) et d'un évaporateur (22) pour sécher et chauffer de l'air de traitement. Un ventilateur (20) est conçu pour faire circuler de l'air dans le système de circulation d'air (2, 20, 24, 25, 41 ; 51). Un passage d’eau (4) et un conduit d'eau (41) guident l'eau provenant de l'évaporateur (22) et du condenseur (21) vers la cuve (11). Le condenseur (21) et l'évaporateur (22) sont disposés sur un côté arrière du tambour (10). L'évaporateur (22) est positionné en amont du condenseur (21). Pour sécher le linge, de l'air est guidé le long d'une direction descendante à travers l'évaporateur (22) puis le condenseur (21).
