Title
(EN) WASHING MACHINE MOLD GROWTH PREVENTION
(FR) PRÉVENTION DU DÉVELOPPEMENT DE MOISISSURES DANS UNE MACHINE À LAVER
Abstract
(EN)
An air inlet pathway and an air outlet pathway are provided which communicate with a water containing enclosure of a laundry washing machine. A blower is provided along at least one of the pathways to move air into the water containing enclosure, and for removal of air, with moisture added thereto, from the enclosure. A heater can optionally be provided along the air inlet pathway to enhance moisture containing properties of the air before entry into the enclosure. A controller can include a humidity sensor within the enclosure (or air outlet pathway) and operate the blower and optionally also the heater when humidity is above an acceptable level, or use a timer to run the blower for a set time. Rotation of a laundry container within the enclosure can also be caused by the controller, to further disrupt mold and mildew growth on the laundry items. A water trap along the air outlet pathway keeps water from escaping the enclosure.
(FR)
Une voie d'entrée d'air et une voie de sortie d'air sont prévus en communication avec une enceinte contenant de l'eau d'une machine à laver le linge. Une soufflante est disposée le long d'au moins l'une des voies pour déplacer l'air à l'intérieur de l'enceinte contenant l'eau, et pour éliminer l'air, avec de l'humidité ajoutée à celui-ci, de l'enceinte. Un dispositif de chauffage peut être disposé facultativement le long de la voie d'entrée d'air en vue d'améliorer les propriétés de l'air contenant de l'humidité avant son entrée dans l'enceinte. Un dispositif de commande peut comprendre un capteur d'humidité à l'intérieur de l'enceinte (ou voie de sortie d'air) et faire fonctionner la soufflante et éventuellement également le dispositif de chauffage lorsque l'humidité est supérieure à un niveau acceptable, ou utiliser un minuteur pour faire fonctionner la soufflante pendant un temps défini. La rotation d'un conteneur de linge à l'intérieur de l'enceinte peut également être provoquée par le dispositif de commande, en vue d'entraver davantage le développement de moisissures et de champignons sur les articles de blanchisserie. Un piège à eau le long de la voie de sortie d'air empêche l'eau de s'échapper de l'enceinte.
