Abstract

L'invention concerne un procédé de séchage d'une machine laveuse-sécheuse intégrée, le procédé comprenant une étape de séchage par centrifugation et d'agitation et une étape de séchage. L'étape de séchage par centrifugation et d'agitation comprend plusieurs étages d'élimination d'eau et des étages d'agitation. Une procédure d'élimination d'eau est exécutée dans chaque étage d'élimination d'eau. L'étage d'agitation se situe entre les étages d'élimination d'eau, et une procédure d'agitation est exécutée dans chaque étape d'agitation. Pendant la mise en œuvre de la procédure d'agitation, il est déterminé si le linge est complètement décollé d'une paroi d'un tambour interne, si tel est le cas, l'étape suivante d'élimination d'eau est exécutée, et si tel n'est pas le cas, la procédure d'agitation est poursuivie. Une procédure de séchage est exécutée dans l'étape de séchage pour sécher le linge. La mise en place d'étapes d'agitation entre les étapes d'élimination d'eau peut garantir que le linge n'est pas collé à la paroi du tambour interne à la fin de l'étape finale d'élimination d'eau, ce qui assure une efficacité de séchage élevée de l'étape de séchage et raccourcit le temps de séchage. De plus, le linge n'est pas susceptible de se froisser, et aucune intervention humaine n'est nécessaire, ce qui permet d'obtenir un lavage intelligent du linge.
