Abstract

La présente invention concerne un système de lave-linge séchant et un procédé de commande correspondant. Le système de lave-linge séchant comprend : un sèche-linge (100) et un lave-linge (200) qui fonctionnent séparément, le lave-linge (200) comprenant un tuyau d'évacuation d'eau pour évacuer l'eau utilisée pour le lavage, et le sèche-linge (100) comprenant un élément d'échange de chaleur (104) et un élément de filtrage d'échange de chaleur (108). Le système de lave-linge séchant comprend en outre un trajet d'eau de rinçage, une extrémité du trajet d'eau de rinçage étant en communication avec le tuyau d'évacuation d'eau et l'autre extrémité de celui-ci étant en communication avec l'élément d'échange de chaleur (104) et/ ou l'élément de filtrage d'échange de chaleur (108), et une soupape de commande est disposée sur le trajet d'eau de rinçage. L'ouverture de la soupape de commande permet à un tuyau d'eau de rinçage d'être commandé de façon à devenir passant, de telle sorte que l'eau utilisée pour le lavage, qui est évacuée du lave-linge (200), est introduite dans l'élément d'échange de chaleur (104) et/ ou l'élément de filtrage d'échange de chaleur (108) du sèche-linge (100) à des fins de rinçage. Dans le système de lave-linge séchant de la présente invention, le lave-linge (200) et le sèche-linge (100) sont conçus de manière à être associés l'un à l'autre, et une utilisation secondaire de l'eau d'évacuation du lave-linge (200) permet d'économiser des ressources d'eau, et de réduire les coûts d'utilisation.
