Opfindelsen angår et gulvbehandlingsapparat med en opretstående, cylindrisk beholder, som i sin øvre del har en indstrømningsåbning for støv indeholdende luft eller væske, en støvudskilningscyklon, som er forbundet med indstrømningsåbningen og har en med den nedre del af beholderen forbundet udstrømningsåbning for udskilt støv og en udstrømningsåbning for renset luft eller væske, et filter, som adskiller sidstnævnte udstrømningsåbning fra sugesiden af mindst ét motorblæseraggregat, hvis trykside er forbundet med en foroven i beholderen anbragt udstrømningsåbning.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a floor treatment apparatus having an upright cylindrical container which has an upper orifice opening for dust containing air or liquid, a purified air or liquid outlet port, a filter separating the latter outlet port from the suction side of at least one motor blower assembly, the pressure side of which is connected to a discharge port located at the top of the container.

Ved kendte apparater af denne art er det sædvanligt at anbringe motorblæseraggregatet over filteret. Dette kræver megen plads og U2U5 2 betyder en ikke ønskelig højde af apparatet.In known apparatus of this kind, it is usual to place the motor fan assembly over the filter. This requires a lot of space and U2U5 2 means an undesirable height of the device.

Gulvbehandlingsapparatet ifølge nærværende opfindelse er ejendommeligt ved, at cyklonen og motorblæseraggregatet er anbragt ved siden af hinanden under det som en liggende plade udformede filter, idet der findes kanaler, som forbinder rummet over filteret med cyklonen og rummet under filteret med motorblæseraggregatet.The floor treatment apparatus according to the present invention is characterized in that the cyclone and the motor fan assembly are arranged side by side under the filter-shaped plate, with channels connecting the space above the filter to the cyclone and the space below the filter to the motor fan assembly.

Ved denne udformning opnås et meget kompakt apparat med et i forhold til apparatets samlede rumfang stort støvrum, og filteret er meget let at adskille, idet det ligger ovenpå såvel cyklonen som motorblæseraggregatet og derfor kan udskiftes uden noget indgreb i disse dele.In this embodiment, a very compact apparatus is obtained with a large dust space, relative to the total volume of the apparatus, and the filter is very easy to separate, as it lies on top of both the cyclone and the engine blower assembly and can therefore be replaced without any intervention in these parts.

Apparatet kan ifølge opfindelsen hensigtsmæssigt være udformet som angivet i krav 2. Derved kan der tilvejebringes et åbent rum imellem det pladeformede filters underside og den tragtformede mellemvæg, således at hele filterets underside udsættes for et ensartet sugetryk.The apparatus according to the invention may conveniently be designed as claimed in claim 2. Thereby an open space can be provided between the underside of the plate-shaped filter and the funnel-shaped partition, so that the entire underside of the filter is subjected to uniform suction pressure.

Ved at udforme apparatet som det er angivet i krav 3 og mere detaljeret i krav 4, opnås en forholdsvis stor sikkerhed imod kortslutning i motoren, idet vanddråber, som suges ind sammen med luften, ikke vil blive ført direkte ind i blæseren, men gennem en kanal, som ligger under blæserens sugeåbning, og sådan væske vil tid efter anden og i mere eller mindre forstøvet tilstand blive ført ind i blæseren, således at mulighed for kortslutning nedsættes væsentligt.By designing the apparatus as set forth in claim 3 and in more detail in claim 4, a relatively high degree of short-circuit protection is obtained in the motor, since water droplets which are sucked in with the air will not be introduced directly into the fan but through a channel which lies below the blower suction opening, and such liquid will be introduced into the fan for a while and in a more or less atomized state, thus substantially reducing the possibility of short circuiting.

I det følgende forklares opfindelsen under henvisning til tegningen, hvor fig. 1 viser et gulvbehandlingsapparat ifølge opfindelsen set i perspektiv, fig. 2 et sprængbillede af apparatets hoveddele set i perspektiv, fig. 3 apparatet set fra siden delvis i snit, fig. 4 apparatets motordel set fra oven, U2A45 3 fig. 5 et snit efter linien V-V i fig. 4, fig. 6 det samme som fig. 2 for en ændret udførelsesform, fig. 7 det samme som fig. 3 for apparatet ifølge fig. 6, fig. 8 et snit efter linien VIII-VIII i fig. 6 med mptorblæserag-gregatet og cyklonudskilleren indsat i kappen» fig. 9 en slangetilslutning set fra siden i perspektiv og fig. 10 et apparat ifølge opfindelsen i forbindelse med et kloset.In the following, the invention is explained with reference to the drawing, in which 1 is a perspective view of a floor treatment apparatus according to the invention; FIG. 2 is a perspective view of an exploded view of the main parts of the apparatus; FIG. 3 is a side sectional view of the apparatus, FIG. 4, the engine part of the apparatus seen from above, U2A45 3 fig. 5 is a section along the line V-V in FIG. 4, FIG. 6 the same as FIG. 2 for a modified embodiment; FIG. 7 the same as FIG. 3 for the apparatus of FIG. 6, FIG. 8 is a section along line VIII-VIII of FIG. 6 with the blower assembly and the cyclone separator inserted into the jacket »FIG. 9 is a perspective view of a hose connection and FIG. 10 shows an apparatus according to the invention in connection with a closet.

Det i figurerne viste gulvbehandlingsapparat 10 består af en beholder 11, som bæres af hjul 12 for apparatets bevægelse hen over en arbejdsflade, X beholderen 10fs øvre del findes en indløbsåbning 13 for støvindeholdende luft eller vaske. Ved hjælp af en ikke vist slange kan arbejdsorganet tilsluttes indløbsåbningen 13· I en . del af beholderens periferi er anbragt $n udblæsningsåbning 14 for den rene luft. Et motorblæseraggregat 15 transporterer luften fra indløbsåbningen 13 til udblæsningsåbningen ,14 gennem en med indløbsåbningen forbundet cyklonudskiller 16, som udgør apparatets første støvudskilningstrin.The floor treatment apparatus 10 shown in the figures consists of a container 11 carried by wheels 12 for movement of the apparatus over a work surface, X the upper part of the container 10, there is an inlet opening 13 for dust-containing air or washing. By means of a hose not shown, the working member can be connected to the inlet opening 13 · In one. part of the periphery of the container is provided with a discharge opening 14 for the clean air. A motor blower assembly 15 transports the air from the inlet opening 13 to the outlet opening, 14 through a cyclone separator 16 connected to the inlet opening, which constitutes the first dust extraction step of the apparatus.

Cyklonudskilleren 16 består af en cylindrisk del 17 og en keglestub-formet nedad indsnævrende del 18, hvis åbning danner udskillerens udløb 19 for støv eller væske. Indløbsåbningen 13 er rettet tangentielt i forhold til udskillerens cylindriske del, således at indkommende støvindeholdende luft eller væske sarttes i kraftig rotation inden i udskilleren.The cyclone separator 16 consists of a cylindrical portion 17 and a cone-shaped downwardly narrowing portion 18, the opening of which forms the discharge 19 of the separator for dust or liquid. The inlet opening 13 is directed tangentially to the cylindrical portion of the separator so that incoming dust-containing air or liquid is sharply rotated within the separator.

En rørstuds, som er koaksialt anbragt i udskillerens i øvrigt luk- . kede cylindriske del danner et luftudløb 20. Oyer rørstudsen er der anbragt en opad åben, tragtformet mellemvæg 21, som i sin periferi har en støtteflade 22 for et filter 23 og med sin nedre åbne ende kommunikerer med motorblæseraggregatets indløbsåbning 24. En over filteret anbragt med en central åbning forsynet kappe 25, fastgø- 4 U2445 relsesorganer 26 og et på undersiden af filteret anbragt gitter 27 holder filteret 23 på plads imod bærefladen 22. Mellem filteret 23’s periferi og beholderen 11rs inderside er udformet en ringformet spalte 28, gennem hvilken luften passerer for at strømme videre over filteret og siden gennem dette imod motorblæseraggregatet 15's indløbsåbning 24.A pipe nozzle which is coaxially disposed in the otherwise closed valve of the separator. bored cylindrical portion forms an air outlet 20. On the tube socket there is arranged an upwardly open, funnel-shaped intermediate wall 21, which at its periphery has a supporting surface 22 for a filter 23 and communicates with its lower open end with the inlet opening of the motor blower assembly 24. a central apertured casing 25, fastening means 26 and a grid 27 located on the underside of the filter hold the filter 23 in place against the support surface 22. Between the periphery of the filter 23 and the inside of the container 11, an annular slot 28 is passed through which the air passes. in order to flow further over the filter and then through it towards the inlet opening 24 of the motor blower assembly 15.

Som det fremgår af fig. 3 og 5 er motorblæseraggregatet 15 anbragt i beholderen 11 i hovedsagelig samme niveau som cyklonudskilleren 16 og ligger ligesom denne under det mellem cyklonudskillerens luftudløb og motorblæseraggregatets indløbsåbning i hovedsagen vandret anbragte filter 23.As shown in FIG. 3 and 5, the motor blower assembly 15 is disposed in the container 11 at substantially the same level as the cyclone separator 16 and is similarly located below the filter 23 arranged horizontally between the air outlet of the cyclone separator and the inlet opening of the motor blower assembly.

Selve filteret 23 er i hovedsagen plant og består af flere overfor hinanden anbragte, en sammenhængende enhed dannende samling af organisk materiale, f.eks. glasfiber. Dets totale tykkelse er ca. 5 cm.The filter 23 itself is generally flat and consists of several interconnected, a continuous unit forming assembly of organic material, e.g. fiberglass. Its total thickness is approx. 5 cm.

Ved kendte apparater har det været sædvanligt at anbringe motorblæ-seraggregatét over filteret. Et sådant arrangement kræver særlig meget plads og betyder en ikke ønskelig højde på apparatet. Ved at motorblæseraggregatet ifølge nærværende opfindelse anbringes i selve beholderen i hovedsagelig samme niveau som cyklonudskilleren,udnyttes det ellers uudnyttede rum omkring udskilleren.In known devices, it has been customary to place the motor fan assembly over the filter. Such an arrangement requires a lot of space and means an undesirable height of the apparatus. By placing the blower assembly of the present invention in the container itself at substantially the same level as the cyclone separator, the otherwise unused space around the separator is utilized.

Det viste apparat kan også anvendes til opsugning af væske ved vådbehandling af overflader. Derved sikrer en elektronisk, ikke nærmere beskrevet niveauføler 29, fig. 5, at strømkredsen til motoren afbrydes ved et vist væskeniveau i beholderen og forhindrer, at væsken stiger til cyklonudskillerens udløb 19·The apparatus shown may also be used for the suction of liquid by wet treatment of surfaces. Thereby an electronic level sensor 29, not described in detail, ensures; 5, the circuit of the motor is disconnected at a certain level of liquid in the container and prevents the liquid from rising to the outlet of the cyclone separator 19 ·

Motoren afkøles af en separat luftstrøm. Som det fremgår af fig. 5» er motorblæseraggregatet forsynet med et hylster 30. Atmosfærisk luft tilføres motorblæseraggregatet gennem en indløbskanal 31 og afgives gennem en udløb’skanal 32 til den omgivne luft efter at have passeret og afkølet motorens vitale dele.The engine is cooled by a separate airflow. As shown in FIG. 5, the blower assembly is provided with a casing 30. Atmospheric air is supplied to the blower assembly through an inlet duct 31 and discharged through an outlet duct 32 to the ambient air after passing and cooling the vital parts of the engine.

Filteret 23, cyklonudskilleren 16 og motorblæseraggregatet 15 er tilgængelige gennem et på passende måde i den øvre del af beholderen 11 anbragt låg 33, som kan åbnes. En i hovedsagen vandret anbragt væg 34 bærer cyklonudskilleren og motorblæseraggregatet samt adskiller 5 142445 filterrummet fra opsamlingsrummet i beholderen 11. Por at opsamlet støv og væske skal kunne faernes, er væggen 34 indrettet til at blive løftet af. En tætningsring 35 er anbragt imellem den øvre og den nedre beholderdel, og disse dele holdes sammen af et snaporgan 36.The filter 23, the cyclone separator 16 and the motor blower assembly 15 are accessible through an openable lid 33 located in the upper portion of the container 11. A generally horizontally disposed wall 34 carries the cyclone separator and the motor blower assembly, and separates the filter compartment from the collection compartment of the container 11. For removal of collected dust and liquid, the wall 34 is arranged to be lifted off. A sealing ring 35 is disposed between the upper and lower container members and these parts are held together by a snap member 36.

For at sænke støjniveauet fra udblæsningsluften, er en lyddsanper 37 i form af en luftpassage mellem to i hovedsagen cirkulære vinger og en modstående væg anbragt imellem motorblæseraggregatets udblæsningsåbning og et udblæsningsgitter 38. Et fjederbelastet organ 39 påvirker motorblæseraggregatets strømafbryder for at forhindre, at motoren startes, uden at der er indsat filter.In order to lower the noise level from the exhaust air, a sound anchor 37 in the form of an air passage between two substantially circular blades and an opposing wall is arranged between the exhaust fan opening and an exhaust grille 38. without a filter inserted.

I et instrumentpanel 40 er samlet manøvreorganer for apparatets styring. Et manøvreskaft 41 letter apparatets håndtering, og en kurv 42, som er anbragt imellem skaftet 41 og beholderen 11, tjener til opbevaring af rengøringsmateriel etc.In an instrument panel 40 are assembled actuators for controlling the apparatus. A maneuvering shaft 41 facilitates the handling of the apparatus, and a basket 42 disposed between the shaft 41 and the container 11 serves for storing cleaning supplies, etc.

Det i det foregående beskrevne gulvbehandlingsapparat virker på følgende måde: . iThe floor treatment apparatus described above operates as follows:. in

Støvindeholdende luft eller væske suges af motorblæseraggregatet i-gennem den tangentielt anbragte indløbsåbning 13 og sættes inden i cyklonudskilleren 16 i kraftig rotation. På grund af cyklonvirkningen udskilles derved større støvpartikler og falder gennem udskillerens koniske del 18 mod beholderen 11's bund. Laboratorieprøver har vist, at det støv, som normalt forekommer i sådanne lokaler, hvortil apparatet er indrettet op til ca. 98-99%, udskilles i cyklonudskilleren. Den resterende støvmængde følger med luft-strømmen gennem udskillerens luftudløb 20 og føres videre på undersiden af den tragtformede mellemvæg 21 og gennem den mellem filterets periferi og beholderen 11’s inderside anbragte spalte 28 til filteret 23. Efter yderligere støvudskilning i filteret 23 strømmer luften på oversiden af mellemvæggen 21 til motorblæseraggregatets indløbsåbning 24, hvorefter den passerer gennem aggregatets skovle og lyddæmperen 27 og afgives til omgivelserne igennem udblæsningsåbningen 14 og gitteret 28.Dust-containing air or liquid is sucked in by the motor blower assembly through the tangentially arranged inlet opening 13 and inserted into the cyclone separator 16 in vigorous rotation. Due to the cyclone effect, larger dust particles are thereby excreted and fall through the tapered part 18 of the separator towards the bottom of the container 11. Laboratory tests have shown that the dust that normally occurs in such rooms to which the apparatus is arranged up to approx. 98-99%, excreted in the cyclone separator. The remaining amount of dust follows the air flow through the air outlet 20 of the separator and is passed on to the underside of the funnel-shaped partition 21 and through the gap 28 to the filter 23 disposed between the periphery of the filter and the inside of the container 11 after further dust separation in the filter 23. the middle wall 21 of the inlet opening 24 of the motor blower assembly, after which it passes through the vanes of the assembly and the muffler 27 and is discharged to the surroundings through the blowout opening 14 and grating 28.

I den anden udførelsesform for opfindelsen er motorblæseraggregatets 6 142445 indløbsåbning rettet nedad imod beholderens indre. Motorblæserag-gregatet er afskærmet fra det øvrige rum i beholderen og står ved hjælp af en ledning i forbindelse med rummet under filteret. Med indsugningsluft en eventuelt medfølgende væske samles på bunden af en motorblæseraggregatet omgivne kappe, hvorfra væsken kan drænes ind i beholderen uden at nå motorblæseraggregatets indløbsåbning.In the second embodiment of the invention, the inlet opening of the motor blower assembly 6 is directed downwardly toward the interior of the container. The motor blower assembly is shielded from the other compartment in the container and is connected by a conduit to the compartment under the filter.
