Abstract

Den foreliggende oppfinnelse vedrører en anordning ; ved en støvsuger som har en sugedyse (14) samt en , støvpose (12) som er koblet til dysen f.eks. ved hjelp av en rørforbindelse (13), en turbovifteenhet (27) drevet av en elektromotor og plassert etter støvposen sett i luftstrømningsretningen. Kompres- sorhjulet (29) i turboviftenheten blir drevet ved en hastighet på mer enn 50 000 omdreininger i minuttet, idet hovedluftstrømmen som oppstår på grunn av tur- bovif teenheten (27) direkte eller indirekte skal forlate enheten via en åpning (30) til atmosfæren. Støvsugeren er utstyrt med organer (45) ved hjelp av hvilke det dannes en sekundær luftstrøm som i det minste delvis avkjøler elektromotoren (32) og som strømmer inn i elektromotoren via en eller flere innganger (44) for kjøleluft som er atskilt fra hovedluftstrømmen.The present invention relates to a device; by a vacuum cleaner having a suction nozzle (14) and a dust bag (12) connected to the nozzle e.g. by means of a pipe connection (13), a turbo fan unit (27) driven by an electric motor and located after the dust bag as seen in the air flow direction. The compressor wheel (29) of the turbo fan unit is driven at a speed of more than 50,000 revolutions per minute, the main air flow resulting from the turbo fan unit (27) directly or indirectly exiting the unit via an opening (30) to the atmosphere . The vacuum cleaner is provided with means (45) by means of which a secondary air stream is formed which at least partially cools the electric motor (32) and which flows into the electric motor via one or more inlets (44) for cooling air separated from the main air stream.
