Abstract

La présente invention vise à proposer une machine à laver dans laquelle une lame d'agitation ne peut pas tourner au ralenti parce qu'elle n'a pas réussi à entrer en contact avec les vêtements, tandis que les vêtements qui ont subi un essorage final ne peuvent pas s'emmêler, de façon à rendre les vêtements moins susceptibles d'être froissés ou endommagés.　À cet effet, la présente invention concerne une machine à laver qui comprend : un boîtier ; une cuve externe qui est supportée à l'intérieur du boîtier d'une manière insensible aux vibrations et qui retient l'eau de lavage à l'intérieur de celle-ci ; une cuve de lavage et d'essorage qui est supportée de manière rotative à l'intérieur de la cuve externe et dans laquelle le linge à laver est logé ; une unité d'entraînement qui entraîne en rotation la cuve de lavage et d'essorage ; une unité de soufflage qui souffle de l'air dans la cuve de lavage et d'essorage ; un orifice d'évacuation à travers lequel l'air provenant de l'unité de soufflage est expulsé depuis le côté supérieur vers le côté inférieur de la cuve de lavage et d'essorage ; et une unité de commande qui commande l'unité d'entraînement et l'unité de soufflage et qui commande également une étape de lavage, une étape de rinçage et une étape d'essorage. L'unité de commande est configurée pour effectuer, après l'étape d'essorage, une étape de démêlage pour entraîner en rotation la cuve de lavage et d'essorage de façon monodirectionnelle et amener de l'air à être expulsé à partir de l'orifice d'évacuation dans la cuve de lavage et d'essorage.
