Abstract

Selon la présente invention, un filtre d'admission d'air (3), un ventilateur (6) et un élément chauffant (11) sont disposés à l'intérieur d'un bâti (2), et un générateur d'ions (5) est disposé entre le filtre d'admission d'air (3) et le ventilateur (6). Ceci fait que de la poussière est moins susceptible d'adhérer au ventilateur (6) du fait d'une charge électrostatique. Des masses de poussière qui ont adhéré au ventilateur (6) sont également empêchées de s'écouler vers l'aval, d'adhérer à l'élément chauffant (11), et de provoquer un déclenchement de feu provoqué par une décharge électrique ; de plus, l'adhérence des masses de poussière aux cheveux est également supprimée.
