De manière générale, la présente invention concerne le domaine du lavage et vise à diffuser un ou plusieurs produits à l'intérieur du tambour lors d'un processus de traitement et / ou de lavage du linge à partir d'un réservoir fixé sur le tambour.In general, the present invention relates to the field of washing and is intended to diffuse one or more products inside the drum during a treatment process and / or laundry from a tank attached to the drum .

La présente invention vise ainsi en particulier à améliorer le traitement et / ou le lavage du linge mis en oeuvre.The present invention thus aims in particular to improve the treatment and / or washing of the laundry used.

On connaît déjà des machines à laver le linge à chargement par le dessus qui proposent d'introduire un ou plusieurs produits à partir d'une boîte à produits, la boîte à produits étant disposée dans le couvercle obturant l'ouverture ménagée dans le boîtier ou encore dans la porte obturant l'ouverture ménagée dans la cuve de lavage.There are already known top-loading laundry washing machines which propose to introduce one or more products from a product box, the product box being disposed in the lid closing the opening in the housing or still in the door closing the opening in the washing tub.

On connaît également des machines à laver le linge à chargement frontal qui proposent d'introduire un ou plusieurs produits à partir d'une boîte à produits disposée dans un tiroir en face frontale de la machine.There are also known front-load washing machines which propose to introduce one or more products from a product box disposed in a drawer on the front of the machine.

Ces machines à laver le linge comprenant une boîte à produits ont une efficacité limitée notamment liée à la mauvaise évacuation du ou des produits contenus dans cette boîte à produits par l'eau circulant à l'intérieur de celle-ci. Des résidus de produits des processus de lavage précédents sont entraînés par l'eau circulant dans la boîte à produits lors des processus de lavage suivants.These washing machines including a product box have a limited effectiveness including the poor evacuation of the product contained in the product box by the water circulating inside thereof. Product residues from the previous wash processes are entrained by the water flowing in the product box during subsequent washing processes.

On connaît d'autre part des réceptacles à disposer directement dans le linge contenu dans le tambour d'une machine à laver le linge.Also known receptacles to be disposed directly in the laundry contained in the drum of a washing machine.

Ces réceptacles ne sont pas hermétiques avant le départ d'un processus de lavage et par conséquent du produit est déversé directement sur le linge. Le produit n'est pas dilué avec de l'eau et engendre des endommagements du linge ou encore des traces de produit sur le linge. Le ou les produits ne se dispersent pas sur la totalité du linge et se concentrent sur une partie de celui-ci.These receptacles are not sealed before the start of a washing process and therefore the product is spilled directly onto the laundry. The product is not diluted with water and causes damage to the laundry or traces of product on the laundry. The product or products do not disperse on the totality of the linen and concentrate on a part of it.

La dissolution du produit dans le bain de la cuve de lavage est mauvaise, en particulier si le produit se déverse sur une pièce de linge.The dissolution of the product in the bath of the wash tub is bad, especially if the product pours on a piece of laundry.

En outre, le produit est obligatoirement utilisé dès le départ du processus de lavage. L'utilisateur ne peut pas choisir à quel moment le produit est utilisé au cours du processus de lavage.In addition, the product is obligatorily used from the beginning of the washing process. The user can not choose when the product is used during the washing process.
