Detta ernås medelst en anordning som erhållit de i patentkraven angivna kännetecknen. 508 524 2 in a simple way makes it possible to change the filter in connection with emptying said container. This is achieved by means of a device which has obtained the features stated in the claims.

Ett utföringsexempel av uppfinningen kommer nu att beskrivas med hänvisning till bifogad ritning på vilken tig 1 är en schematisk vertikalprojektion som visar en dammsugare försedd med en cyklonavskiljare under det att fig 2 är ett schematiskt vertikalsnitt genom cyklonavskiljaren.An embodiment of the invention will now be described with reference to the accompanying drawing, in which Fig. 1 is a schematic vertical projection showing a vacuum cleaner provided with a cyclone separator while fi g 2 is a schematic vertical section through the cyclone separator.

Fig 1 visar en dammsugare som innefattar ett dammsugarhus 10 inneslutande en vakuumkålla i form av ett motorfläktaggregat 11. Fläktens inloppsida står i förbindelse med en cyklonavskiljare 12 anordnad vid dammsugarens främre del under det att cyklonavskiljaren via en slang 13, ett rörhandtag 14 och ett rörskaft 15 kommunicerar med ett munstycke 16.Fig. 1 shows a vacuum cleaner comprising a vacuum cleaner housing 10 enclosing a vacuum source in the form of a motor kt power unit 11. The inlet side of the fan communicates with a cyclone separator 12 arranged at the front part of the vacuum cleaner while the cyclone separator via a hose 13, a pipe handle 14 and a pipe handle 15 communicates with a nozzle 16.

Cyklonavskiljaren 12 har dels en inloppsdel 17 formad som en stos till vilken slangen 13 kopplas, dels en utloppsdel 18 som på icke närmare visat sätt är ansluten till fläktaggregatets 11 inloppssida och dels en, mellan inloppsdel och utloppsdel placerad cyklondel. Cyklondelen innefattar ett cirkulärcylindriskt cyklonhus 19 i vilken inloppsdelen 17 mynnar så att den inströmmande luften får en i huvudsak tangentiellt riktning. Cyklonhuset övre gavel täcks av ett lock 20 med en centralt anordnad nedåtriktad hylsa 21 som kommunicerar med sagda utloppsdel 18. Locket är lösbart anordnat på cyklonhuset och kvarhålles vid detta medelst byglar 22.The cyclone separator 12 has partly an inlet part 17 formed as a socket to which the hose 13 is connected, partly an outlet part 18 which is connected in a manner not shown in more detail to the inlet side of the coupling unit 11 and partly a cyclone part placed between inlet part and outlet part. The cyclone part comprises a circular-cylindrical cyclone housing 19 in which the inlet part 17 opens so that the inflowing air has a substantially tangential direction. The upper end of the cyclone housing is covered by a lid 20 with a centrally arranged downwardly directed sleeve 21 which communicates with said outlet part 18. The lid is releasably arranged on the cyclone housing and is retained thereby by means of stirrups 22.

Mellan locket 20 och cyklonhuset är den yttre periferin av en gallerforrnad, skâlad tilterhållare 23 inklämd. Demia filterhållare utgör ett stöd för ett pä hållaren uppträtt filter 24 av engångstyp. Filtret 24 är företrädesvis utfört av rel. tunt luftgenomsläppligt papper och är skålformat varvid dess yttre periferi är inklämd mellan motsvarande delar hos sagda filterhâllare 23 och cyklonhuset 19. För att öka ñlterytan kan ñlterhållaren istället utformas med ett antal nedåt utskjutande ribbor vilka omsluts av filtret och mellan vilka filtret får vecka sig under användning.Between the lid 20 and the cyclone housing, the outer periphery of a grid-shaped, clad tilter holder 23 is clamped. Demia filter holders are a support for a disposable filter type 24 held on the holder. The filter 24 is preferably made of rel. thin air-permeable paper and is cup-shaped with its outer periphery sandwiched between corresponding parts of said filter holder 23 and the cyclone housing 19. To increase the filter surface, the container holder can instead be formed with a number of downwardly projecting ribs which are enclosed by the filter and between .

Cyklonhusets nedre del uppvisar ett kragforrnat parti 25 och innefattar en insats 26 som huvudsakligen har formen av en upp och nedvänd ihålig kon med en 508 524 3 nedre öppning 27 som vetter mot en uppsamlingsbehållare 28 för av cyklonen avskiljda partiklar. Cyklonhuset 19 vilar med sitt kragforrnade parti 25 på behållaren och kvarhålls vid denna medelst ett antal klämmor 29.The lower part of the cyclone housing has a collar-shaped portion 25 and comprises an insert 26 which is substantially in the form of an inverted hollow cone with a lower opening 27 facing a collecting container 28 for particles separated by the cyclone. The cyclone housing 19 rests with its collared portion 25 on the container and is retained thereon by means of a number of clamps 29.

Behållaren 28 innesluter en cirkulär platta 30 som medelst glest placerade distansorgan 31 är fixerad ovanför behållarens botten 32 varigenom det bildas en kammare 33 mellan plattan 30 och botten 32. Plattan 30 har en något mindre diameter än behållarens innerdiameter varigenom det skapas en periferiell springa 34 mellan behållarväggen och sagda platta 30. Ev. är också plattan perforerad. Kammaren 33 är medelst en nippel 35 och en rörförbindelse 36 ansluten till utloppsdelen 19 via en icke visad ventil. Behållaren 28 innesluter också en påse 37 av icke luftgenomsläppligt material ex.vis plast varvid påsen är inklämd mellan det kragformade partiet 25 och behållarens övre kant.The container 28 encloses a circular plate 30 which by means of sparsely placed spacers 31 is fixed above the bottom 32 of the container thereby forming a chamber 33 between the plate 30 and the bottom 32. The plate 30 has a slightly smaller diameter than the inner diameter of the container thereby creating a peripheral gap 34 between the container wall and said plate 30. Possibly. the plate is also perforated. The chamber 33 is connected by means of a nipple 35 and a pipe connection 36 to the outlet part 19 via a valve (not shown). The container 28 also encloses a bag 37 of non-air-permeable material, eg plastic, the bag being sandwiched between the collar-shaped portion 25 and the upper edge of the container.

Anordningen ftmgerar på följande sätt. När dammsugaren startas insuges luft genom inloppsdelen 17 in i cyklonhuset 19 där det bildas en virvel runt ñltret 24 varigenom tyngre partiklar slungas mot cyklonhusets periferi och genom gravitationens inverkan faller mot påsens 37 botten. Den delvis renade luften som befinner sig i centrum av cyklonhuset bringas därefter att avgå genom filtret 24 till utloppsdelen 18 vilket medför ett luften renas i ytterligare ett steg innan den avgår till omgivningen.The device operates in the following manner. When the vacuum cleaner is started, air is sucked in through the inlet part 17 into the cyclone housing 19 where a vortex is formed around the filter 24 whereby heavier particles are thrown towards the periphery of the cyclone housing and by the action of gravity fall towards the bottom of the bag 37. The partially purified air located in the center of the cyclone housing is then vented through the filter 24 to the outlet portion 18 which causes the air to be purified in a further step before departing to the surroundings.

För att tömma cyklonavskiljaren lyftes locket 20 och filterhållaren 23 vilket medför att engångsfiltret 24 faller ner i påsen 37. Genom att därefter avlägsna cyklonhuset 19 från behållaren 28 kan påsen 37 lyftas ur behållaren 28 och kastas med sitt irmehåll. Vid insättning av en ny påse i behållaren klärns påsen fast mellan kragpartiet 25 och behållarens 28 övre del varefter dammsugaren igånsättes. Normalt står därvid den ovan nämnda, icke visade, ventilen i öppet läge. Detta medför att det uppstår ett undertryck i kammaren 33 varvid tryckdifferensen mellan behållarens 28 insida och utloppsdelen 18 kommer att medföra att luft som befinner sig mellan påsen och behållarväggen kommer att utsugas genom rörförbindelsen 36 varigenom påsen 37 kommer till anliggning mot behällarväggen och mot plattan 30. I de fall man ej 508 524 4 önskar använda en påse i behållaren stängs sagda ventil.To empty the cyclone separator, the lid 20 and the container holder 23 are lifted, which means that the disposable filter 24 falls into the bag 37. By subsequently removing the cyclone housing 19 from the container 28, the bag 37 can be lifted out of the container 28 and thrown away with its contents. When inserting a new bag into the container, the bag is clamped between the collar portion 25 and the upper part of the container 28, after which the vacuum cleaner is started. Normally, the above-mentioned, not shown, valve is in the open position. This causes a negative pressure in the chamber 33 whereby the pressure difference between the inside of the container 28 and the outlet part 18 will cause air present between the bag and the container wall to be sucked out through the pipe connection 36 whereby the bag 37 comes into contact with the container wall and the plate 30. In cases where it is not desired to use a bag in the container, said valve is closed.

För att underlätta att engångsfiltret 24 faller ner i behållaren 28 kan løcket 20 integreras med ñlterhållaren 23 varvid lockets yttre periferi formas koniskt under det att filtrets yttre delar på motsvarande sätt skjuter snett uppåt utåt från behållaren.In order to facilitate that the disposable filter 24 falls into the container 28, the lid 20 can be integrated with the container 23, the outer periphery of the lid being conically shaped while the outer parts of the filter correspondingly project obliquely upwards outwards from the container.
