Abstract

ESTA INVENCION RELATA A UN DISPOSITIVO PARA UN ASPIRADOR QUE TIENE UNA TOBERA DE SUCCION Y UNA BOLSA DE POLVO (12) QUE ESTA CONECTADA A LA TOBERA POR EJEMPLO POR MEDIO DE UN CONEXION DE TUBO, UNA UNIDAD (27) DE TURBOVENTILADOR (27) ACCIONADA POR UN MOTOR ELECTRICO Y COLOCADO DESPUES DE LA BOLSA DE POLVO VISTA EN LA DIRECCION DEL FLUJO. EL IMPULSOR (29) DE LA UNIDAD DE TURBOVENTILADOR ESTA ACCIONADA A UNA VELOCIDAD QUE ES SUPERIOR A 50.000 RPM AL FLUJO DE AIRE PRIMARIO CREADO POR LA UNIDAD DE TURBOVENTILADOR (27) ESTANDO DISPUESTA PARA DIRECTAMENTE O INDIRECTAMENTE SALIR A LA UNIDAD POR UNA SALIDA (30) A LA ATMOSFERA. EL ASPIRADOR ESTA PROVISTO CON MEDIOS (45) POR MEDIO DE LOS CUALES UN FLUJO DE AIRE SECUNDARIO ES CREADO EL CUAL AL MENOS PARCIALMENTE ENFRIA EL MOTOR ELECTRICO (32) Y EL CUAL FLUYE DENTRO DEL MOTOR ELECTRICO POR UNA O DIVERSAS ENTRADAS (44) PARA ENFRIAR EL AIRE QUE ESTA SEPARADO DEL FLUJO DE AIRE PRIMARIO.THIS INVENTION RELATES TO A DEVICE FOR A VACUUM CLEANER THAT HAS A SUCTION NOZZLE AND A DUST BAG (12) THAT IS CONNECTED TO THE NOZZLE BY EXAMPLE THROUGH A TUBE CONNECTION, A TURBO-VENTILATOR UNIT (27) BY AN ELECTRIC MOTOR AND PLACED AFTER THE DUST BAG SEEN IN THE DIRECTION OF THE FLOW. THE TURBO-VENTILATOR UNIT IMPELLER (29) IS OPERATED AT A SPEED THAT IS GREATER THAN 50,000 RPM TO THE PRIMARY AIR FLOW CREATED BY THE TURBO-VENTILATOR UNIT (27) BEING ARRANGED TO DIRECTLY OR INDIRECTLY EXIT THE UNIT BY A DEPARTURE (30 ) TO THE ATMOSPHERE. THE VACUUM CLEANER IS PROVIDED WITH MEANS (45) THROUGH WHICH A SECONDARY AIR FLOW IS CREATED WHICH IS AT LEAST PARTIALLY COOLING THE ELECTRIC MOTOR (32) AND WHICH FLOWS WITHIN ONE OR MORE INLETS (44) FOR COOL THE AIR THAT IS SEPARATED FROM THE PRIMARY AIR FLOW.
