Description

Vifte, særlig for støvsugere. Fan, especially for vacuum cleaners.

Oppfinnelsen angår en elektromotorisk The invention relates to an electromotive

drevet vifte, særlig for støvsugere. Slike vifter har i alminnelighet to vingehjul som befinner seg på hver sin side av en ledeskive, som samtidig bærer lageret på viftesiden, mens det annet lager, som sit-ter på motorsiden, er anbragt i motorens omgivende kapsel, resp. i en lagerbøyle. De to lagre ligger således forholdsvis langt fra hverandre, da motoren, dennes kommutator og det ene av vingehjulene befinner seg mellom dem. driven fan, especially for vacuum cleaners. Such fans generally have two impellers located on either side of a guide disc, which at the same time carries the bearing on the fan side, while the other bearing, which sits on the motor side, is placed in the motor's surrounding capsule, resp. in a stock bracket. The two bearings are thus relatively far apart, as the motor, its commutator and one of the impellers are located between them.

For oppfinnelsen er der nu stillet den For the invention, it is now set

oppgave å minske lageravstanden, noe som er gunstig av kjente grunner. Dette oppnås ved at ledeskiven i sitt midtparti er trukket inn mot motoren, slik at lageret som er anbragt i dette inntrukne parti, er flyttet nærmere til motoren, resp. til dennes kommutator. Vingehjulet på motorsiden blir svarende til ledeskiven likeledes trukket task of reducing the bearing distance, which is beneficial for known reasons. This is achieved by the guide disc in its central part being pulled in towards the motor, so that the bearing which is placed in this retracted part is moved closer to the motor, resp. to its commutator. The impeller on the engine side is similarly pulled, corresponding to the guide disc

inn, slik at lageret på viftesiden, som nevnt, bare blir stående i kort avstand ved siden av motoren eller dennes kommutator og avstanden mellom de to lagre dermed blir minsket i ikke ubetydelig grad. Samtidig blir der oppnådd en fordelaktig luftføring takket være inntrekningen av ledeskiven og vingehjulene — hensiktsmessig trekker man også det annet vingehjul inn tilsvarende. in, so that the bearing on the fan side, as mentioned, only stands a short distance next to the motor or its commutator and the distance between the two bearings is thus reduced to a not inconsiderable extent. At the same time, an advantageous airflow is achieved thanks to the retracting of the guide disc and the impellers — appropriately, the other impeller is also retracted accordingly.

Tegningen viser et utførelseseksempel på oppfinnelsens gjenstand. The drawing shows an embodiment of the object of the invention.

Fig. 1 viser snitt av en støvsugers motor- og viftedel, og Fig. 1 shows a section of a vacuum cleaner's motor and fan part, and

fig. 2 viser viften i større målestokk fig. 2 shows the fan on a larger scale

og likeledes i snitt. and likewise on average.

1 betegner drivmotoren, 2 dens aksel og 3 dens kommutator, mens 4 er kullbørstene. 5 og 6 er viftens to vingehjul og 7 den mel-lomliggende ledeskive. Akselen 2 er lagret dels med et lager 8 i en lagerbøyle 9 og dels med et lager 10 i ledeskiven 7. 1 denotes the drive motor, 2 its shaft and 3 its commutator, while 4 is the carbon brushes. 5 and 6 are the fan's two impellers and 7 the intermediate guide disc. The shaft 2 is supported partly by a bearing 8 in a bearing bracket 9 and partly by a bearing 10 in the guide disc 7.

Overensstemmende med oppfinnelsen er midtpartiet 11 av ledeskiven 7, hvori lageret 10 er innsatt, trukket inn i retning mot motoren, så lageret 10 kommer nær hen til kommutatoren og avstanden mellom lagrene 8 og 10 blir forkortet tilsvarende. På tilsvarende måte er likeledes vingeh julet 5 og hensiktsmessig også det annet vingehjul 6 trukket inn ved 12 i retning mot motoren, og der fremkommer ved denne utformning av viften dessuten en meget god tilførsel av luften som antydet med piler på tegningen. In accordance with the invention, the middle part 11 of the guide disc 7, in which the bearing 10 is inserted, is drawn in towards the motor, so that the bearing 10 comes close to the commutator and the distance between the bearings 8 and 10 is shortened accordingly. In a similar way, the vane wheel 5 and appropriately also the other vane wheel 6 are pulled in at 12 in the direction towards the engine, and this design of the fan also results in a very good supply of air as indicated by arrows in the drawing.
