An appliance having a driving mechanism is provided, the appliance (10) comprising two rotatable portions (32, 34) which are rotatable by the driving mechanism (50) about an axis (40). The driving mechanism (50) comprises a gearbox (60) having an input gear (116), two output gears (240, 304) and a locking mechanism (250, 252, 318) movable between a first position and a second position. The arrangement is such that, when the locking mechanism (250, 252, 318) is in the first position and the input gear (116) is driven, both output gears (240, 304) rotate in the same direction and, when the locking mechanism (250, 252, 318) is in the second position and the input gear (116) is driven, the output gears (240, 304) rotate in opposite directions. The arrangement of the axis (40) is horizontal or substantially horizontal. The invention is particularly suitable for use in a front-loading washing machine (10) having a drum (30) comprising two rotatable portions (32, 34). The driving mechanism (50) can be used to selectively cause rotation of the rotatable portions (32, 34) either in the same direction or in opposite directions.

L'invention concerne un appareil ménager à mécanisme d'entraînement, l'appareil (10) comprenant deux parties rotatives (32, 34), sous l'action du mécanisme (50), autour d'un axe (40). Le mécanisme d'entraînement (50) comprend une boîte d'engrenage (60) avec un engrenage d'entrée (116), deux engrenages de sortie (240, 304) et un mécanisme de verrouillage (250, 252, 318) passant d'une première à une seconde position et vice versa. Lorsque le mécanisme de verrouillage (250, 252, 318) est en première position et que l'engrenage d'entrée (116) est entraîné, les deux engrenages de sortie (240, 304) tournent dans la même direction, et lorsque ce mécanisme (250, 252, 318) est en seconde position et que l'engrenage d'entrée (116) est entraîné, les engrenages de sortie (240, 304) tournent dans des directions opposées. L'axe (40) est horizontal ou sensiblement horizontal. L'arrangement décrit est particulièrement approprié à une machine à laver à chargement frontal (10) avec un tambour (30) comprenant deux partie rotatives (32, 34). Le mécanisme d'entraînement (50) permet la rotation sélective des parties rotatives (32, 34) dans la même direction ou dans des directions opposées.
