Abstract

La présente invention concerne un système de transmission de sèche-linge, comprenant un tambour (2) destiné à contenir des vêtements, un ventilateur (3) destiné à souffler de l'air vers le tambour (2) et un moteur (4) destiné à entraîner le tambour (2). Le moteur (4) est raccordé au ventilateur (3) et entraîne le ventilateur (3) en rotation ; un mécanisme de transmission d'inversion est raccordé en série entre le moteur (4) et le ventilateur (3) ; le mécanisme de transmission d'inversion peut contraindre le ventilateur (3) à ne pas suivre la rotation inversée du moteur (4) lorsque le moteur (4) inverse la direction de rotation. En disposant un mécanisme de transmission d'inversion entre le moteur (4) et le ventilateur (3) dans le système de transmission de sèche-linge, lorsque le moteur (4) entraîne le tambour (2) à tourner vers l'avant et vers l'arrière, par commande du mécanisme de transmission d'inversion, le ventilateur (3) peut continuer sa rotation dans une direction de telle sorte que le problème d'enchevêtrement de vêtements pendant la rotation vers l'avant et vers l'arrière du moteur (4) soit résolu, le ventilateur (3) peut fournir un volume d'air stable dans une même direction et l'uniformité et l'efficacité du séchage des vêtements sont améliorées.
