Abstract
Description
Foreliggende oppfinnelse vedrører generelt en vaskelansett av den typen som blir benyttet for eksempel til vasking av de utvendige delene på kjøretøy. Slike vaskelansetter innbefatter normalt et løp som har et høytrykksmunnstykke som blir benyttet for å rette en høytrykks-vannstråle mot de ytre delene av kjøretøyet. Slike vaskelansetter er normalt forsynt med trykksatt vann fra en pumpe drevet av en elektromotor eller en bensinmotor, og i mange tilfeller blir vaskemidlet matet inn i vannstrømmen i posisjon med pumpen. Mer spesifikt vedrører den foreliggende oppfinnelse en vaskelansett som angitt i ingressen til krav 1. The present invention generally relates to a washing lancet of the type that is used, for example, for washing the external parts of vehicles. Such washing lancets normally include a barrel which has a high-pressure nozzle which is used to direct a high-pressure water jet towards the outer parts of the vehicle. Such washing lancets are normally supplied with pressurized water from a pump driven by an electric motor or a petrol engine, and in many cases the detergent is fed into the water stream in position with the pump. More specifically, the present invention relates to a washing lancet as stated in the preamble to claim 1.
FR-1,363.426 fremlegger en vaskelansett som har et blandekammer der en aksielt rettet vannstråle suger inn luft fra et luftinntak og vaskemiddel fra et vaskemiddelinntak, og danner et skum som blir sprøytet ut aksielt fra utløpet av kammeret. Luftinntaket og vaskemiddelinntaket er diametralt motsatt plassert inne i blandekammeret. FR-1,363,426 discloses a washing lancet which has a mixing chamber where an axially directed water jet draws in air from an air inlet and detergent from a detergent inlet, forming a foam which is sprayed out axially from the outlet of the chamber. The air intake and the detergent intake are diametrically opposed inside the mixing chamber.
FR-A-2.519.881 fremlegger en håndholdt vaskelansett som har to løp montert på et felles legeme, og ventilhjelpemidler inkorporert i legemet til lansetten, og som kan betjenes av brukeren for å kople trykksatt fluid fra et inntak på et løp til et inntak på et annet løp, der løpene er arrangert for å danne stråler av ulik karakter, og der ventilhjelpemidlene innbefatter et fritt bevegelig ventilelement som holdes tilbake av fluidtrykket for å selektivt blokkere nevnte inntak. FR-A-2,519,881 discloses a hand-held washing lancet having two barrels mounted on a common body, and valve aids incorporated in the body of the lancet, operable by the user to connect pressurized fluid from an inlet on one barrel to an inlet on another barrel, wherein the barrels are arranged to form jets of different character, and wherein the valve aids include a freely movable valve element retained by the fluid pressure to selectively block said intake.
I FR-A-2.519.881 er imidlertid de to løpene plassert side om side og det bevegelige ventilelementet er bevegelig ved å helle lansetten noe om sin lengdeakse. In FR-A-2,519,881, however, the two barrels are placed side by side and the movable valve element is movable by tilting the lancet slightly about its longitudinal axis.
Siden bare ett av løpene er forbundet med en vaskemiddelbeholder, og løpene uansett er av ulike lengder og hullstørrelser, oppstår et ubalansert arrangement som ikke er ergonomisk. Since only one of the runners is connected to a detergent container, and the runners are anyway of different lengths and hole sizes, an unbalanced arrangement occurs which is not ergonomic.
Et ytterligere problem med arrangementet nevnt ovenfor er at ventilelementet enkelt ruller fra en side til en annen hvis trykket blir avbrutt, slik at det er mulig å slå om til en vaskemiddelstrøm ved et uhell. Dette kan være farlig siden vaskemiddel noen ganger er etsende. A further problem with the arrangement mentioned above is that the valve element easily rolls from one side to another if the pressure is interrupted, so that it is possible to switch to a detergent flow accidentally. This can be dangerous as detergent is sometimes caustic.
US-A-4202495 fremlegger en munnstykkehodevelger for et eller flere munnstykker plassert i enden av et enkelt løp, der velgeren er plassert på enden av munnstykket til løpet. Velgeren har en omstillingsanordning utformet av en kule som beveger seg ved hjelp av tyngdekraften når trykket blir skrudd av for å tillate omstilling av strålene uten å endre munnstykkehodet, der strålen blir valgt bare ved å vri på løpet. En slik omstillingsanordning som er plassert i munnstykkeenden er istand til å operere under lavere trykk og selv om noe lekkasje kan være akseptabelt i munnstykkeenden, er ingen lekkasje akseptabel i brukerenden av en vaskelansett. US-A-4202495 discloses a nozzle head selector for one or more nozzles located at the end of a single barrel, where the selector is located at the end of the nozzle of the barrel. The selector has an adjustment device formed by a ball which moves by gravity when the pressure is turned off to allow adjustment of the jets without changing the nozzle head, the jet being selected simply by turning the barrel. Such a switching device which is placed at the nozzle end is capable of operating under lower pressure and although some leakage may be acceptable at the nozzle end, no leakage is acceptable at the user end of a washing lancet.
Den foreliggende oppfinnelse søker å i det minste delvis å redusere de forutgående vanskelighetene. The present invention seeks to at least partially reduce the foregoing difficulties.
I henhold til denne oppfinnelsen, er det tilveiebragt en vaskelansett kjennetegnet ved de i krav 1 angitte trekk. According to this invention, a washing lancet characterized by the features specified in claim 1 is provided.
Andre foretrukne særtrekk ved oppfinnelsen blir definert i de avhengige kravene. Other preferred features of the invention are defined in the dependent claims.
Det ovenfor nevnte arrangementet er mer ergonomisk enn det i FR-A-2.519.881 og spesielt i forhold til US-A.4202495 ved spesielt å ha et ventilhjelpemiddel som innbefatter et langstrakt bueformet (fortrinnsvis halvsirkulært) kammer som har et inntak og som har respektive avdelte uttak i kommunikasjon med løpene, et rullende eller glidende ventilelement (som for eksempel en stålkule) som er plassert i kammeret og som blir arrangert for å beveges inne i kammeret for å blokkere en av utløpene ved tilting av lansetten og å blokkere andre av utløpene automatisk (det vil si ved tyngdekraftens påvirkning) når trykket blir avbrutt. Lansetten blir fortrinnsvis tilveiebragt med utløsermidler for å blokkere fluidtrykket for å muliggjøre en slik bevegelse av ventilelementet og for at fluidtrykk som anvendes på nytt skal opprettholde ventilelementet i posisjon mot det sist blokkerte utløpet ved fluidtrykk uavhengig av helningsvinkelen til lansetten. The above-mentioned arrangement is more ergonomic than that of FR-A-2,519,881 and especially in relation to US-A.4202495 in particular having a valve aid comprising an elongated arcuate (preferably semi-circular) chamber having an inlet and having respective compartmentalized outlets in communication with the barrels, a rolling or sliding valve member (such as a steel ball) located in the chamber and arranged to be moved within the chamber to block one of the outlets by tilting the lancet and to block others by the outlets automatically (that is, by the influence of gravity) when the pressure is interrupted. The lancet is preferably provided with release means to block the fluid pressure to enable such a movement of the valve element and for fluid pressure that is applied again to maintain the valve element in position towards the last blocked outlet by fluid pressure regardless of the angle of inclination of the lancet.
Fortrinnsvis er imidlertid ventilelementene låst ved fluidtrykk som tillater raskt bytte i sammenligning med et ikke-låsende, manuelt operert arrangement som medfører en betydelig forsinkelse og deling av strømmen. Preferably, however, the valve elements are locked by fluid pressure which allows rapid switching as compared to a non-locking, manually operated arrangement which involves a significant delay and splitting of the flow.
Ytterligere foretrukne særtrekk blir definert i de avhengige kravene. Additional preferred features are defined in the dependent claims.
En foretrukket utførelsesform av oppfinnelsen er beskrevet nedenfor ved hjelp av eksempel bare, med henvisning til figurene 1 og 2 av de vedlagte tegninger hvori: Figur IA er et langsgående tverrsnitt som viser den proksimale enden og midtpartiet til en vaskelansett i henhold til den foreliggende oppfinnelse, figur IB viser det mest fjerntliggende partiet av vaskelansetten fra figur IA, og figur 2 er et snitt langs linjen H-II i figur IA. A preferred embodiment of the invention is described below by way of example only, with reference to figures 1 and 2 of the attached drawings in which: Figure IA is a longitudinal cross-section showing the proximal end and the middle part of a washing lancet according to the present invention, figure IB shows the most distant part of the washing lancet from figure IA, and figure 2 is a section along the line H-II in figure IA.
Ved å henvise til figur IA, er en langstrakt vaskelansett vist som innbefatter et vanninntak 1 tilveiebragt med en utløserfastgjøring (ikke vist) for å påføre og utløse vann under trykk. Vanninnløpet 1 kommuniserer med en ventil som innbefatter en stålkule 14 som løper innenfor et halvsirkulært kuleventilkammer 16 som best vises i figur 2. Kulen 14 har en nedre standardposisjon der den blokkerer et innløp 18 til et skumløp 12, og har en øvre posisjon hvorved det blokkerer et innløp 17 til et trykkstrømsløp 5 som genererer en vannstråle. Som vist i figur 2, er veien til stålkulen 14 mellom disse to ytterposisj onene tallsirkulær og følgelig kan den bli beveget mellom disse to posisjonene ved å helle lansetten om sin lengdeakse etter utløsing av trykket med utløserfastgj øringen forbundet med vanninnløpet 1. Referring to Figure IA, an elongated washing lancet is shown which includes a water inlet 1 provided with a trigger attachment (not shown) for applying and releasing water under pressure. The water inlet 1 communicates with a valve which includes a steel ball 14 running within a semi-circular ball valve chamber 16 which is best shown in Figure 2. The ball 14 has a lower standard position where it blocks an inlet 18 of a foam chute 12, and has an upper position where it blocks an inlet 17 to a pressurized flow 5 which generates a water jet. As shown in figure 2, the path of the steel ball 14 between these two outer positions is numerically circular and consequently it can be moved between these two positions by tilting the lancet about its longitudinal axis after releasing the pressure with the release fastener connected to the water inlet 1.
En vannstråle blir dannet inne i et blandekammer 19 av en venturidyse 3 som blir forsynt med høytrykksvann i kanalen 6 fra innløpet 18. Den resulterende strålen trekker inn vaskemiddel 11 via et materør 10, en sokkel 8, en vaskemiddelkanal 7 og en nåleventil 2 som regulerer strømmen av vaskemiddel inn i blandekammeret 19. Den resulterende blandingen av vann og vaskemiddel går ut av blandekammeret via en ytterligere venturidyse 4 som trekker inn luft på grunn av venturivirkning gjennom et annulært luftinntak 20 som kommuniserer med en annulær passasje 21 (figur IB) som i sin tur har et luftinntak 23 som går ut i den omliggende luften. Blandingen av luft, vann og vaskemiddel som passerer langs skumløpet 12 blir omdannet til skum i et nett 13 (figur IB) og danner en strøm av vaskeskum. Nettet er et konvensjonelt nett av plastmateriale (polypropylen eller nylon). A water jet is formed inside a mixing chamber 19 by a venturi nozzle 3 which is supplied with high-pressure water in the channel 6 from the inlet 18. The resulting jet draws in detergent 11 via a feed tube 10, a base 8, a detergent channel 7 and a needle valve 2 which regulates the flow of detergent into the mixing chamber 19. The resulting mixture of water and detergent exits the mixing chamber via a further venturi nozzle 4 which draws in air due to venturi action through an annular air intake 20 which communicates with an annular passage 21 (Figure 1B) as in in turn has an air intake 23 which exits into the surrounding air. The mixture of air, water and detergent that passes along the foam course 12 is converted into foam in a net 13 (figure IB) and forms a stream of washing foam. The net is a conventional net made of plastic material (polypropylene or nylon).
Den annulære passasjen 21 strekker seg aksielt med lansetten rundt skumløpet 12 og i dens ende som er fjerntliggende fra den enden som er koplet til luftinntaket 20 er det tilveiebragt en eller flere aksielt utstrekkende vegger som er perifert plassert om den ytre perifere overflaten av skumløpet 12 og som avgrenser passasjer derimellom som kommuniserer med den utvendige luften via en eller flere åpninger 23 i den ytre overflaten av skumløpet 12 forutgående for, men tilliggende skumnettet 13 i bevegelsesretningen til vann, vaskemiddel og luftblandingen gjennom skumløpet 12. Når luft er påkrevet, trekkes det derfor gjennom åpning 23 inn i passasjen mellom veggene 22 og så inn i venturien 4 via den annulære passasjen 21 og luftinntaket 20. En avtagbar vaskemiddelbeholder 9 utstyrt med sitt eget vaskemiddelmaterør 10 og tilknyttede hette er festbar til sokkelen 8 ved hjelp av en standard bajonettkopling (ikke vist). The annular passage 21 extends axially with the lancet around the foam barrel 12 and at its end remote from the end connected to the air intake 20 one or more axially extending walls are provided which are peripherally located about the outer peripheral surface of the foam barrel 12 and which delimit passages in between that communicate with the outside air via one or more openings 23 in the outer surface of the foam run 12 preceding, but adjacent to, the foam net 13 in the direction of movement of water, detergent and the air mixture through the foam run 12. When air is required, it is therefore drawn through opening 23 into the passage between the walls 22 and then into the venturi 4 via the annular passage 21 and the air intake 20. A removable detergent container 9 equipped with its own detergent feed tube 10 and associated cap is attachable to the base 8 by means of a standard bayonet coupling (not shown).
Med henvisning til figur 2, skal det bemerkes at kulen 14 normalt vil falle til den nedre posisjonen ved hvilken den blokkerer innløpet 18 under tyngdekraftens virkning. Ved utløsing av vanntrykket ved innløpet 1 og å helle lansetten 180° mot klokka om dens lengdeakse, kan kulen 14 bli beveget for å blokkere innløpet 17, og på dette punktet kan trykket bli anvendt på nytt av utløseren (ikke vist) for å opprettholde kulen i denne posisjonen og danne en skumstråle ved strømning gjennom innløpet 18 til blandekammeret 19. Når det er ønskelig å vaske vekk skummet, blir vanntrykket Referring to Figure 2, it should be noted that the ball 14 will normally fall to the lower position at which it blocks the inlet 18 under the action of gravity. By releasing the water pressure at the inlet 1 and tilting the lancet 180° anti-clockwise about its longitudinal axis, the ball 14 can be moved to block the inlet 17, at which point the pressure can be reapplied by the trigger (not shown) to maintain the ball in this position and form a foam jet by flowing through the inlet 18 to the mixing chamber 19. When it is desired to wash away the foam, the water pressure
øyeblikkelig frigjort ved å utløse utløseren, lansen blir så helt noe om sin lengdeakse for å gjøre det mulig for kulen 14 å rulle tilbake til sin nedre posisjon, og fluidtrykket blir så anvendt på nytt av utløseren for å tillate vannet å strømme direkte via et innløp 17 til det øvre løpet for å danne en vaskestråle. momentarily released by releasing the trigger, the lance is then pivoted somewhat about its longitudinal axis to enable the ball 14 to roll back to its lower position, and the fluid pressure is then reapplied by the trigger to allow the water to flow directly via an inlet 17 to the upper race to form a wash jet.
Vaskelansetten i henhold til den foreliggende oppfinnelse kan bli benyttet ikke bare for vasking av kjøretøyer, men også for andre rengjøringsapplikasjoner, som for eksempel slakterirenhold. The washing lancet according to the present invention can be used not only for washing vehicles, but also for other cleaning applications, such as butchery cleaning.
