  Elektrischer Staubsaugapparat. 



   Bei Staubsaugapparaten mit eingebautem elektrischem Motor und Zentrifugalflügelpumpe wird der Durchmesser des Gehäuses nach demjenigen des Flügelrades gerichtet, so dass das weite

   Gemäss der vorliegenden Erfindung kann der Staubsaugapparat mit einem relativ sehr grossen, also   auch sehr wirksamen Flügelrad   versehen sein. ohne das Gewicht. Form und Handlichkeit des Apparates   dadurch nachteilig beeinflusst werden und wird   ferner eine sehr vorteilhafte Motorkühlung und günstige Saugwirkung erzielt.

   PATENT-ANSPRÜCHE :
1. Staubsaugapparat, dadurch gekennzeichnet, dass der vertikale Motor zwischen dem   senkrecht übereinander   liegenden Flügelrad und Filter gleichachsig angeordnet ist.

  Electric vacuum cleaner.



   In vacuum cleaners with a built-in electric motor and centrifugal vane pump, the diameter of the housing is aligned with that of the impeller, so that the widening

 placement costs and cumbersome handling. In addition, the air used for cooling is inadequately directed to the engine.



   According to the present invention, the vacuum cleaner can be provided with a relatively very large, and therefore also very effective, impeller. without the weight. The shape and handiness of the device are thereby adversely affected and a very advantageous engine cooling and favorable suction effect is also achieved.

   PATENT CLAIMS:
1. Vacuum cleaner, characterized in that the vertical motor is arranged coaxially between the vertically superimposed impeller and filter.

Claims

2. Vacuum cleaner according to claim 1, characterized in that the impeller is arranged in the foot of the motor or the vacuum cleaner.

3. Vacuum cleaner according to claim 1, characterized in that the vertical motor is arranged on the suction side of the pump.

4. Vacuum cleaner according to claim 1, characterized in that the impeller is arranged coaxially below the vertically superposed filter and motor.

5. Dust accumulator according to claim 1, characterized in that the air passage opening is arranged below the motor so that the air is drawn together in a narrow column, the axis of which coincides with the motor axis and the air passes through the motor in its longitudinal axis.

6. Vacuum cleaner, characterized in that the housing for the impeller is arranged protruding below the apparatus housing.

7. Vacuum cleaner, characterized in that the impeller housing is provided with openings or perforations shaped in such a way that the exhaust air is expelled in a tangential direction to the housing.

8. Vacuum cleaner, characterized in that in the circumference of the impeller housing formed into channels DurrhlassÏffnungen for the exhaust air are arranged tangentially to the impeller and in its direction of rotation.
