Abstract

L'invention concerne un purificateur d'air facile à déplacer, comprenant : une enceinte de corps principal sur laquelle sont formés un orifice d'admission et un orifice de soufflage donnant vers l'extérieur et possédant un évent reliant entre eux l'orifice d'admission et l'orifice de soufflage; un moyen de soufflage qui introduit l'air intérieur dans l'évent et qui est intégré dans l'enceinte de corps principal; un élément de suppression d'odeur prévu sur l'évent et dans lequel l'air introduit peut passer; une unité de chauffage qui chauffe localement l'élément de suppression d'odeur; un moyen de changement de position qui modifie la relation de position relative entre l'unité de chauffage et l'élément de suppression d'odeur; et un moyen de commande qui commande le moyen de soufflage, l'unité de chauffage et le moyen de changement de position. L'élément de suppression d'odeur se caractérise en ce que la fonction de suppression d'odeur est rétablie lorsqu'il est chauffé par l'unité de chauffage (63). Le bas de l'enceinte de corps principal possède des roues. Le sommet de l'enceinte de corps principal est dotée d'une poignée possédant un manche en forme de tige. Le manche de la poignée s'étend de gauche à droite par rapport à l'enceinte de corps principal. Les roues sont configurées pour tourner au moins dans le sens de la longueur du manche.
