Abstract

La présente invention concerne une tête de diffuseur et un appareil de nettoyage d'air la comprenant. Une tête de diffuseur (1 ;11, 18 ; 23 ;31 ; 43) est conçue pour l'application locale d'air purifié à une cible (39), ledit diffuseur ayant un corps principal (8 ; 12 ; 20 ; 24) doté d'une surface d'entrée d'air (3 ; 15 ; 28 ; 33), qui présente une première zone (A1), vers une surface de sortie d'air (4 ; 16 ; 19 ; 26 ; 34), qui a une seconde zone (A2) qui est plus grande que la première zone (A1). Le corps principal (8 ; 12 ; 20 ;24) est doté d'une pluralité de conduits d'air à expansion continue (2 ; 14 ; 22 ; 27 ; 32) qui s'étendent dans le sens de la longueur entre la surface d'entrée d'air (3 ; 15 ; 28 ; 33) et la surface de sortie d'air (4 ; 16 ; 19 ; 26 ; 34) , un conduit d'air (2 ; 14 ; 22 ; 27 ; 32) présente une troisième aire de section transversale (A) qui augmente de façon continue à partir d'une entrée de conduit d'air (5) au niveau de ladite surface d'entrée d'air (3 ; 15 ; 28 ; 33) vers une sortie de conduit d'air (6 ; 22) au niveau de ladite surface de sortie d'air (4 ; 16 ; 19 ; 26 ; 34). Si un moyen formant filtre (36) est placé au niveau de la surface d'entrée d'air (3 ; 15 ; 28 ; 33), la tête de diffuseur peut être utilisée dans un appareil de nettoyage d'air doté d'un moyen formant pompe pour l'admission d'air depuis l'environnement ambiant.
