Abstract

La présente invention concerne une soufflante pour un vêtement climatisé et un vêtement climatisé. Ladite soufflante permet de maintenir un environnement confortable à l'intérieur du vêtement puisqu'une sensation de chaleur est supprimée. Le vêtement offre un excellent niveau de confort lorsqu'il est porté et d'excellentes propriétés de conception, même lorsque le vêtement est porté dans un bureau ou à la maison, par exemple. À cette fin, l'essentiel de la soufflante pour vêtement climatisé de la présente invention réside dans une soufflante permettant l'entrée d'air extérieur entre le vêtement et le corps, caractérisée en ce que : la soufflante comprend au moins un ventilateur, un moteur, une batterie, une borne de charge et un commutateur d'une source d'alimentation ; le ventilateur, le moteur et la batterie sont logés dans un boîtier ; le boîtier a un orifice d'admission pour permettre l'entrée d'air extérieur et un orifice de soufflage pour introduire dans le vêtement l'air extérieur qui a été admis ; la borne de charge et une partie de fonctionnement du commutateur de la source d'alimentation sont disposées sur l'extérieur du boîtier ; et l'épaisseur du boîtier dans la direction de l'axe du ventilateur est comprise entre 5 et 30 mm.
