Title (EN) ALARM DEVICE FOR AN ELECTRIC VACUUM CLEANER
(FR) DISPOSITIF D"ALARME POUR UN ASPIRATEUR ELECTRIQUE
Abstract: front page image
(EN)An electric vacuum cleaner in which, when the suction load to a fan motor (3) exceeds a predetermined value, the external air is drawn bypassing a filter (8) and simultaneously generating an alarm sound. Generating and stopping the alarm sound can be performed without direct effects upon the drawing of bypass air to the fan motor (3), which makes the vacuum cleaner more convenient to use and prevents burning out of the fan motor (3).
(FR)Aspirateur electrique dans lequel, lorsque la charge d"aspiration d"un moteur de turbine (3) depasse une valeur predeterminee, l"air exterieur est aspire en derivation d"un filtre (8) et simultanement un signal d"alarme est produit. La production et l"arret du signal d"alarme peuvent etre obtenus sans agir directement sur l"aspiration de l"air en derivation par le moteur de turbine (3), ce qui rend l"utilisation de l"aspirateur plus pratique et empeche de mettre le moteur de turbine (3) en court-circuit.
