Description

Priključek sesalnika za prahVacuum cleaner connector

Predmetni izum se nanaša na priključek sesalnika za prah. Po mednarodni klasifikaciji patentov so izumi te vrste uvrščeni na področje gospodinjskih aparatov, namreč sesalnikov in v okviru slednjih k priboru zanje.The present invention relates to a vacuum cleaner connector. According to the international classification of patents, inventions of this kind are classified in the field of household appliances, namely vacuum cleaners and within their accessories.

Pri tem je izum osnovan na problemu, kako zasnovati priključek, ki bo na povsem enak način kot vsakokrat preostali priključki namestljiv na vsakokrat razpoložljivo sesalno cev sesalnika in ki bo omogočal učinkovito čiščenje tudi najtežje dostopnih območij, npr. notranjih robov, reg, reber in vogalnih območij, ne zgolj z odsesavanjem ampak tudi s sočasnim ščetkanjem.The invention is based on the problem of how to design a connector that will be installed in exactly the same way as the rest of the connectors on the vacuum cleaner tube that is available at all times, and which will allow efficient cleaning of even the hardest accessible areas, e.g. internal edges, regs, ribs and corner areas, not only by vacuuming but also by brushing at the same time.

Na uvodoma opisanem področju tehnike so znani številni sesalniki in tudi številni priključki, ki so po izbiri uporabljivi skupaj z vsakokratnim sesalnikom in od katerih je vsak namestljiv na sesalno cev sesalnika in prirejen za uporabo v določenih pogojih. Nekateri priključki so namenjeni za čiščenje reg, drugi za čiščenje ravnih površin. Relevantna skupina priključkov poleg sesalnega ustja, skozi katero vstopa zračni tok in s seboj v smeri proti sesalni cevi in zatem v notranjosti sesalnika odnaša delce nečistoč, obsega tudi vrtljivo ščetko.Many vacuum cleaners and numerous attachments are known in the art described above, which are optionally usable together with the respective vacuum cleaner, each of which is adjustable to the vacuum cleaner tube and adapted for use in certain conditions. Some connectors are for cleaning regs, others for cleaning flat surfaces. In addition to the suction nozzle through which the airflow enters and carries the impurity particles inside the vacuum cleaner, the relevant group of connectors also includes particles of impurities, including a rotating brush.

Nekatere od tovrstnih pripomočkov so opisani npr. v US 2002/0042966 Al, US 5,249,333, US 2002/0108210 Al in US 2001/0011403 Al. Vsem tem znanim pripomočkom je skupnoSome of these gadgets are described e.g. in US 2002/0042966 Al, US 5,249,333, US 2002/0108210 Al and US 2001/0011403 Al. All these known gadgets are common

- da obsegajo ohišje, kije prirejeno za namestitev na sesalno cev sesalnika za prah,- that they comprise a housing designed to be fitted to the suction hose of a vacuum cleaner,

- da omenjeno ohišje obsega vstopno odprtino in izstopno odprtino, v območju katere je priključek povezljiv s sesalno cevjo sesalnika, in da je skozi omenjeno ohišje med vstopno in izstopno odprtino omogočen karseda neoviran pretok zraka vsaj v smeri proti sesalni cevi sesalnika,- said housing comprises an inlet and an outlet in the area of which the connection is connected to the suction tube of the vacuum cleaner, and that through said housing between the inlet and outlet openings, as much as possible unobstructed airflow is possible at least in the direction of the vacuum cleaner tube,

- da obsegajo rotacijsko ščetko, ki je pri vseh zgoraj naštetih rešitvah vgrajena v omenjenem ohišju, in sicer na tak način, da je okoli svoje osi vrtljivo vgrajena v notranjosti ohišja in preko ustreznega prenosnika gnana s pomočjo turbine, ki je prav tako okoli svoje osi prosto vrtljivo uležajena v notranjosti ohišja in gnana s pomočjo v notranjosti ohišja razpoložljivega, proti sesalni cevi sesalnika usmerjenega zračnega toka, pri čemer del obodnega območja omenjene ščetke sega izven omenjenega ohišja.- that they comprise a rotary brush which is incorporated in said housing in all the above solutions, in such a way that it is rotatably mounted about its axis inside the housing and driven through a suitable gearbox by means of a turbine which is also about its axis freely rotatably housed inside the housing and driven internally by an accessible, directional airflow suction tube of the vacuum cleaner, with a portion of the circumferential area of said brush extending beyond said housing.

Zgoraj omenjene rešitve se med seboj sicer razlikujejo v nekaterih podrobnosti, ki pa so pretežno vezane na preusmeritev zračnega toka z namenom izboljšanja učinkovitosti pogona turbine in preprečevanja zastajanja z zračnim tokom transportiranih delcev v določenih območjih v notranjosti ohišja. Pri tem je očitno, da so tovrstne rešitve kvečjemu primerne za čiščenje razmeroma obsežnih ravnih površin, še zlasti vsaj približno horizontalnih, pri čemer je učinkovito čiščenje na osnovi kombinacije sesanja in ščetkanja možno zgolj na razmeroma velikem odmiku od robov in v lahko dostopnih območjih. Ker je ščetka obdana z razmeroma obsežnim ohišjem, ne more priti v stik s težje dostopnimi površinami v regah, vogalih ali v območju notranjih robov.The aforementioned solutions differ in some details, but they are mainly related to the diversion of air flow in order to improve the efficiency of the turbine drive and to prevent the airflow of the transported particles in certain areas inside the housing. It is obvious that such solutions are best suited for cleaning relatively large flat surfaces, especially at least approximately horizontal ones, whereby effective cleaning based on a combination of suction and brushing is only possible at relatively large edges and in easily accessible areas. Because the brush is surrounded by a relatively large body, it cannot come into contact with harder-to-reach surfaces in slots, corners or in the inner edges area.

Pričujoči izum se nanaša na priključek sesalnika za prah, kakršen obsega ohišje, ki je prirejeno za namestitev na sesalno cev vsakokrat razpoložljivega sesalnika za prah, pri čemer omenjeno ohišje obsega vsaj eno vstopno odprtino in vsaj eno izstopno odprtino, v območju katere je priključek povezljiv s sesalno cevjo sesalnika, in pri čemer je skozi omenjeno ohišje med vstopno in izstopno odprtino omogočen karseda neoviran pretok zraka vsaj v smeri proti sesalni cevi sesalnika, in pri čemer priključek nadalje obsega rotacijsko ščetko, ki je vrtljiva okoli svoje osi in preko vsakokrat razpoložljivega prenosnika gnana s pomočjo zračne turbine, ki je prav tako okoli svoje osi prosto vrtljivo uležajena v notranjosti ohišja in gnana s pomočjo med uporabo priključka v notranjosti ohišja razpoložljivega, proti sesalni cevi sesalnika usmerjenega zračnega toka.The present invention relates to a vacuum cleaner connector such as a housing which is adapted to be fitted to a vacuum cleaner tube of a vacuum cleaner available at all times, said housing having at least one inlet and at least one outlet in which the attachment is connected to the suction pipe of the vacuum cleaner, allowing the unobstructed air flow through the said housing between the inlet and outlet openings at least in the direction towards the suction pipe of the vacuum cleaner, and the attachment further comprising a rotary brush rotatable about its axis and driven through the gearbox available at any time. by means of an air turbine which is also freely rotatably mounted about its axis inside the housing and driven by the aid of the available airflow directed suction pipe of the available vacuum cleaner inside the housing.

Po izumu je priključek tako zasnovan, daje rotacijska ščetka v celoti razporejena izven ohišja priključka. Pri tem je rotacijska os ščetke prednostno razporejena na prostem koncu iz ohišja štrlečega konzolnega nosilca, prenosnik za pogon ščetke s pomočjo zračne turbine pa je prednostno vgrajen v omenjenem konzolnem nosilcu.According to the invention, the attachment is designed so that the rotary brush is fully disposed outside the attachment housing. Preferably, the rotary axis of the brush is disposed at the free end from the housing of the projecting cantilever carrier, and the brush drive gear unit by means of an air turbine is preferably incorporated in said cantilever carrier.

Nadalje je prenosnik prednostno jermenski prenosnik, ki je lahko izbran iz skupine, ki jo glede na vsakokrat razpoložljiv prenosni element tvorijo prenosniki z jermenom gladkega ploščatega, enostransko narebrenega ploščatega ali trapeznega ali krožnega prečnega prereza skupaj z vsakokrat razpoložljivima vsaj dvema jermenicama. Pri tem je premer z zračno turbino povezane pogonske jermenice prednostno manjši od premera jermenice, s katero je povezana ščetka.Furthermore, the gearbox is preferably a belt drive, which may be selected from the group consisting of gear units with a smooth flat, single-stranded flat or cross-section or circular cross-section, together with at least two pulleys, in each case depending on the transmission element available. The diameter of the air turbine connected drive pulley is preferably smaller than the diameter of the pulley to which the brush is connected.

Po izbiri je prenosnik lahko izbran tudi iz skupine, ki jo tvorijo vrvni prenosniki, verižni prenosniki ali zobniški prenosniki.Optionally, the laptop may also be selected from the group consisting of rope laptops, chain gears or gears.

Še nadalje je za priključek po izumu značilno, da je v ohišju, namreč v območju vstopnega ustja, predviden zasun za spreminjanje prečnega preseka odprtine vstopnega ustja in s tem spreminjanje hitrosti zračnega toka v območju zračne turbine. Pri tem je prednostno, če je omenjeni zasun mehansko povezan z upravljalnim gumbom, ki je razporejen na zunanji površini ohišja, tako da je s spremembo položaja omenjenega gumba možno spremeniti položaj zasuna.Furthermore, the connection according to the invention is characterized by the fact that in the housing, namely in the area of the inlet mouth, a latch is provided for changing the cross-section of the inlet mouth opening and thereby changing the air flow rate in the area of the air turbine. Preferably, said latch is mechanically coupled to a control knob arranged on the outer surface of the housing so that by changing the position of said knob it is possible to change the position of the latch.

Izum bo v nadaljevanju podrobneje obrazložen s primerom izvedbe, ki je ponazorjen na priloženi skici, kjer kažeThe invention will now be explained in more detail by way of an embodiment illustrated in the accompanying drawing showing

Sl. 1 priključek sesalnika za prah, deloma v vzdolžnem prerezu,FIG. 1 vacuum cleaner connector, partly in longitudinal section,

Sl. 2 priključek v prerezu v ravnini II - II po Sl. 1.FIG. 2 is a cross-sectional view in plane II - II according to FIG. 1.

Priključek sesalnika za prah obsega ohišje 1, ki je s svojim ustrezno oblikovanim izstopnim ustjem 11 prirejeno za namestitev na neprikazano sesalno cev vsakokrat razpoložljivega in na skici prav tako neprikazanega sesalnika za prah.The vacuum cleaner connector comprises a housing 1, which, with its properly shaped outlet nozzle 11, is adapted to be fitted to a vacuum cleaner tube which is not always shown and not shown in the drawing.

Omenjeno ohišje 1 obsega vsaj eno v območju vstopnega ustja 12 razporejeno vstopno odprtino in vsaj eno v območju izstopnega ustja 11 razporejeno izstopno odprtino, v območju katere je priključek povezljiv s sesalno cevjo sesalnika. Temu ustrezno je skozi omenjeno ohišje 1 med vstopno in izstopno odprtino omogočen karseda neoviran pretok zraka vsaj v smeri proti sesalni cevi sesalnika.Said housing 1 comprises at least one outlet opening arranged in the area of the inlet mouth 12 and at least one outlet opening in the area of the outlet mouth 11 in the region of which the connection is connected to the vacuum cleaner tube. Accordingly, through said housing 1, an unobstructed air flow at least between the inlet and outlet openings is possible, at least in the direction of the intake manifold.

Priključek nadalje obsega rotacijsko ščetko 2, ki je vrtljiva okoli svoje osi 20 in preko vsakokrat razpoložljivega prenosnika 3 gnana s pomočjo zračne turbine 4, ki je prav tako okoli svoje osi 40 prosto vrtljivo uležajena v notranjosti ohišja 1 in gnana s pomočjo med uporabo priključka v notranjosti ohišja 1 razpoložljivega, proti sesalni cevi sesalnika usmerjenega zračnega toka, ki je na Sl. 1 shematično ponazorjen z ustreznima puščicama. Po izumu je omenjena rotacijska ščetka 2 v celoti razporejena izven ohišja priključka. Pri tem je ščetka 2 prednostno tako izbrana, da je njena širina v primerjavi z zunanjim premerom razmeroma majhna, vendar pa ta značilnost v ničemer ne predstavlja nikakršne omejitve obsega samega izuma. Prav tako je zaradi čiščenja ali iz drugih praktičnih razlogov običajno prednostno, če ščetine 21 omenjene ščetke 2 sestojijo iz termoplastičnega polimernega gradivaThe attachment further comprises a rotary brush 2 which is rotatable about its axis 20 and driven via a gearbox 3 by means of an air turbine 4, which is also freely rotatably mounted about its axis 40 inside the housing 1 and driven by the aid of using the attachment in inside the housing 1 of the available, directional airflow vacuum cleaner tube shown in FIG. 1 is schematically illustrated with appropriate arrows. According to the invention, said rotary brush 2 is completely disposed outside the housing of the connector. Preferably, the brush 2 is so selected that its width is relatively small compared to the outer diameter, but this characteristic in no way constitutes any restriction on the scope of the invention itself. It is also generally advantageous for cleaning or other practical reasons if the bristles 21 of said brush 2 consist of thermoplastic polymer material

Po izumu je nadalje prednostno, če je rotacijska os 20 ščetke 2 razporejena na prostem koncu 130 iz ohišja 1 štrlečega konzolnega nosilca 13, tako da je prenosnik 3 za pogon ščetke 2 s pomočjo zračne turbine 4 vgrajen kar v omenjenem konzolnem nosilcu 13. Prenosnik 3 je prednostno kar jermenski prenosnik, ki je lahko izbran iz skupine, ki jo glede na vsakokrat razpoložljiv prenosni element tvorijo prenosniki z jermenom 30 gladkega ploščatega, enostransko narebrenega ploščatega ali trapeznega ali krožnega prečnega prereza skupaj z vsakokrat razpoložljivima vsaj dvema jermenicama 31, 32, od katerih je ena pogonska in ena gnana, pri čemer je pogonska jermenica 31 povezana s turbino 4, gnana jermenica 32 pa s ščetko 2. Pri tem je z vidika praktične uporabe običajno prednostno, če je premer z zračno turbino 4 povezane pogonske jermenice 31 manjši od premera gnane jermenice 32, s katero je povezana ščetka 2.According to the invention, it is further advantageous if the rotary axis 20 of the brush 2 is disposed at the free end 130 from the housing 1 of the projecting cantilever carrier 13 such that the gear 3 for driving the brush 2 by means of an air turbine 4 is mounted in said cantilever carrier 13. The transmission 3 is preferably a belt drive, which may be selected from the group consisting of laptops 30 with a smooth flat, single-stranded flat or trapezoidal or circular cross-section, together with at least two pulleys 31, 32, from one driven and one driven, the drive pulley 31 being connected to the turbine 4 and the driven pulley 32 to the brush 2. In practical terms, it is usually preferred if the diameter of the air turbine 4 of the connected drive pulley 31 is less than the diameter of the driven pulley 32 to which the brush 2 is connected.

Po izbiri pa je omenjeni prenosnik 3 lahko izbran iz skupine, ki jo tvorijo vrvni prenosniki, verižni prenosniki ali zobniški prenosniki.Optionally, said gear 3 may be selected from the group consisting of rope gears, chain gears or gears.

Še nadalje je v ohišju 1, namreč v območju vstopnega ustja 12, predviden zasun 14 za spreminjanje prečnega preseka odprtine vstopnega ustja 12 in s tem spreminjanje hitrosti zračnega toka v območju zračne turbine 4. Omenjeni zasun • · je prednostno kar mehansko povezan z upravljalnim gumbom 15, ki je razporejen na zunanji površini ohišja 1, tako da je s spremembo položaja omenjenega gumba 15 možno spremeniti položaj zasuna 14. Ker zračni tok skozi ohišje 1 ustvarja s priključkom preko sesalne cevi povezan sesalnik, je hitrost toka v območju turbine 4 odvisna od velikosti prečnega prereza odprtine vstopnega ustja 12 ohišja 1. S premikom upravljalnega gumba 15 proti levi po Sl. 1 dosežemo zasuk zasuna 14 in s tem zmanjšanje velikosti prečnega prereza odprtine vstopnega ustja 12, s čimer se v območju turbine 4 poveča hitrost zračnega toka. To ima za posledico povečanje vrtilne hitrosti turbine 4, kar se preko prenosnika 3 odrazi na povečanju vrtilne hitrosti ščetke 2. Zatem je s premikom upravljalnega gumba 15 proti desni možno na strokovnjaku nedvomno razumljiv način vrtilno hitrost ščetke 2 po izbiri tudi zmanjšati.Furthermore, in the housing 1, namely in the area of the inlet mouth 12, a latch 14 is provided for changing the cross-section of the inlet outlet opening 12 and thereby changing the air flow rate in the area of the air turbine 4. Said latch • is preferably mechanically connected to the control knob. 15, which is arranged on the outer surface of the housing 1, so that by changing the position of said button 15 it is possible to change the position of the latch 14. Since the air flow through the housing 1 creates a vacuum cleaner connected to the suction pipe connection, the flow rate in the area of the turbine 4 depends on of cross-sectional size of the inlet mouth opening 12 of the housing 1. By moving the control knob 15 to the left according to FIG. 1, a latch 14 is achieved, thereby reducing the cross-sectional size of the inlet orifice opening 12, thereby increasing the airflow velocity in the area of turbine 4. This results in an increase in the speed of the turbine 4, which through the laptop 3 is reflected in an increase in the rotational speed of the brush 2. Then, by moving the control knob 15 to the right, it is possible for an expert to understand, in an expertly understood manner, the rotational speed of the brush 2 optionally.
