Abstract

L'invention concerne une machine à laver et à sécher apte à empêcher l'obstruction d'un filtre de conduit d'air par l'évacuation des amas de peluches générés dans un conduit d'air allant du côté arrière du filtre de conduit d'air à un ventilateur. Ladite machine à laver et à sécher est caractérisée en ce qu'elle comprend : un tambour (11) qui contient le linge et tourne pendant chacune des étapes de lavage, de rinçage et de drainage ; une cuve externe (10) qui entoure le tambour (11) et stocke de l'eau ; un canal de drainage (70) qui évacue l'eau dans la cuve externe (10) ; des ventilateurs (32, 33) qui fournissent de l'air au tambour (11) et à la cuve externe (10) ; un conduit d'air (39) reliant la cuve externe (10) et les ventilateurs ; un filtre de conduit d'air (36) qui est disposé entre la cuve externe (10) et le conduit d'air (39) et qui collecte les peluches allant en direction d'un orifice d'aspiration du conduit d'air (39) ; et un canal d'évacuation de peluches (9) relié à une extrémité au conduit d'air (39) et relié à l'autre extrémité au canal de drainage (70), le conduit d'air (39) étant doté d'un évidement (39a) en retrait vers le tambour (11), une extrémité (9a) du canal d'évacuation de peluches (9) étant reliée à l'évidement (39a), et la surface arrière du canal d'évacuation de peluches (9) étant logée plus loin vers l'intérieur que la surface arrière du conduit d'air (39) tel que vu dans une section transversale latérale du tambour (11) et du canal d'évacuation de peluches (9).
