Støvsuger.Vacuum cleaner.
Description
Oppfinnelsen vedrører en støvsuger med efterkoblet filter og et motorvifteaggregat hvis viftehjul er anordnet i et viftehus som tilføres støvholdig luft. The invention relates to a vacuum cleaner with a downstream filter and a motor fan assembly whose fan wheel is arranged in a fan housing which is supplied with dusty air.
I teknikken er det generelt kjent støvsugere av ovennevnteVacuum cleaners of the above are generally known in the art
art. Vanligvis dreier det seg her om håndstøvsugere hvor det bak et såkalt motorhode er anordnet en filterpose. species. Usually, this concerns hand vacuum cleaners where a filter bag is arranged behind a so-called motor head.
I det såkalte motorhode befinner det seg et motorvifteaggregat hvis viftehjul løper i et viftehus som tilføres støv-holdig luft. Fra viftehuset blir luften drevet inn i den tilsluttende filterpose. Ved en slik oppbygning er det mulig at støv og tråder og lignende samler seg bak viftehjulet og at trådene f.eks. vikler seg rundt motorakselen som rager inn i viftehuset. Denne motoraksel bærer viftehjulet og lagres med et lager i viftehusbunnen. En videre ulempe er at smussen kan ødelegge lageret. Det er påvist at smuss, tråder og lignende blir trukket inn under viftehjulet på grunn av trykk-forholdene ved viftehjulet. In the so-called motor head, there is a motor fan assembly whose fan wheel runs in a fan housing which is supplied with dust-containing air. From the fan housing, the air is driven into the connecting filter bag. With such a structure, it is possible that dust and threads and the like collect behind the fan wheel and that the threads e.g. wraps around the motor shaft which protrudes into the fan housing. This motor shaft carries the fan wheel and is stored with a bearing in the bottom of the fan housing. A further disadvantage is that the dirt can destroy the bearing. It has been proven that dirt, threads and the like are drawn in under the fan wheel due to the pressure conditions at the fan wheel.
Oppfinnelsens oppgave er å eliminere de ovennevnte ulemper, dvs. å avtette viftehjulundersiden mot smuss. The task of the invention is to eliminate the above-mentioned disadvantages, i.e. to seal the underside of the fan wheel against dirt.
Ifølge oppfinnelsen løses denne oppgave ved at viftehjuletAccording to the invention, this task is solved by the fan wheel
på viftehjulundersiden har en rundtgående krave som har en mindre diameter enn viftehjulskovlene og som befinner seg i inngrep med en fordypning i viftehusbunnen. on the underside of the fan wheel has a circumferential collar which has a smaller diameter than the fan wheel blades and which engages with a recess in the fan housing bottom.
Et ytterligere trekk ved oppfinnelsen er at fordypningen harA further feature of the invention is that the recess has
en vegg som vender i viftehjulets retning, hvilken vegga wall facing the direction of the fan wheel, which wall
sammen med fordypningen og viftehjulets rundtgående krave danner en såkalt labyrint. together with the recess and the surrounding collar of the fan wheel form a so-called labyrinth.
Oppfinnelsen har således den avgjørende fordel at viftehjulundersiden er avtettet mot inntrengende støv, tråder og lignende og at lageret som befinner seg nedenfor viftehjulet i viftehusbunnen beskyttes mot smuss og således mot ødeleggelse. The invention thus has the decisive advantage that the underside of the fan wheel is sealed against penetrating dust, threads and the like and that the bearing located below the fan wheel in the bottom of the fan housing is protected against dirt and thus against destruction.
I det følgende skal det beskrives et utførelseseksempel på oppfinnelsen under henvisning til tegningen hvor In what follows, an embodiment of the invention will be described with reference to the drawing where
fig. 1 viser en håndstøvsuger med motorhode og filter og fig. 2 viser et utsnitt av viftehuset hvor labyrinten er synlig. fig. 1 shows a handheld vacuum cleaner with motor head and filter and fig. 2 shows a section of the fan housing where the labyrinth is visible.
I fig. 1 vises en håndstøvsuger 10 som består av et såkalt motorhode 11, et efterkoblet filter 12 og en føringsstang 13. In fig. 1 shows a hand-held vacuum cleaner 10 which consists of a so-called motor head 11, a downstream filter 12 and a guide rod 13.
Støvsugeren 10 suger ved hjelp av et motor-vifteaggregat 14, som befinner seg i det såkalte motorhode 11 og ikke er vist, luft til seg og driver den inn i det efterkoblete filter 12. The vacuum cleaner 10 sucks in air with the help of a motor-fan unit 14, which is located in the so-called motor head 11 and is not shown, and drives it into the downstream filter 12.
Viftehuset 15 har den i fig. 2 viste oppbygning. Viftehjulet 1 løper i viftehuset 15 og bæres av motorakselen 16 som er lagret i viftehusbunnen 7 ved hjelp av et kulelager 17 og bærer viftehjulet 1. The fan housing 15 has the one in fig. 2 showed structure. The fan wheel 1 runs in the fan housing 15 and is carried by the motor shaft 16 which is stored in the fan housing bottom 7 by means of a ball bearing 17 and carries the fan wheel 1.
Viftehjulet 1 har på viftehjulsundersiden 2 en rundtgående krave 3 som imidlertid ikke avslutter viftehjulet 1, men med sin omkrets 4 ligger innenfor viftehjulskovlenes 5 omkrets 18. Denne krave 3 rager inn i fordypningen 6 ved viftehusbunnen 7. For å oppnå en bedre avtetning på vifte-li julsundersiden 2 mot smuss, tråder o.l., er det anordnet en vegg, 8 foran fordypningen 6 på viftehusbunnen 7. Sammen med fordypningen 6 og den rundtgående krave 3 danner den en såkalt labyrint 9. Fordi den rundtgående krave 3 ligger innenfor viftehjulskovlenes 5 omkrets 18, er det tilstrekkelig plass for viftediffusoren 19. Kulelageret 17 samt viftehjulundersiden 2 og motorakselen 16 beskyttes således mot smuss, tråder o.1. The fan wheel 1 has on the fan wheel underside 2 a circumferential collar 3 which, however, does not terminate the fan wheel 1, but with its circumference 4 lies within the circumference 18 of the fan wheel blades 5. This collar 3 projects into the recess 6 at the fan housing bottom 7. In order to achieve a better seal on the fan on the underside 2 against dirt, threads etc., a wall 8 is arranged in front of the recess 6 on the fan housing bottom 7. Together with the recess 6 and the circumferential collar 3, it forms a so-called labyrinth 9. Because the circumferential collar 3 lies within the circumference 18 of the fan wheel blades 5 , there is sufficient space for the fan diffuser 19. The ball bearing 17 as well as the underside of the fan wheel 2 and the motor shaft 16 are thus protected against dirt, threads etc.
