Abstract

L'invention concerne un aspirateur électrique (1) qui comprend un moteur électrique, une chambre de collecte de poussière (8), ainsi qu'un conduit d'air de travail (10). Le moteur électrique entraîne une soufflante (9) qui présente un côté aspiration (S) et un côté pression (D) et qui est placée en aval de la chambre de collecte de poussière (8), le côté aspiration (S) étant raccordé au conduit d'air de travail (10) lorsque l'air est évacué librement dans le milieu ambiant. L'invention vise à améliorer un aspirateur électrique de ce type en ce qui concerne son comportement d'évacuation de l'air. A cet effet, l'air est évacué librement par l'intermédiaire d'un espace d'évacuation extérieur (23) qui s'étend en recouvrant une partie de la chambre de collecte de poussière (8).
