Fremgangsmåte og anordning for rengjøring av .lyskasterglass på motorkjøretøyer e.l. Procedure and device for cleaning headlight glass on motor vehicles etc.

Nærvorarende oppfinnelse vedrører en ny fremgangsmåte- for rengjøringThe present invention relates to a new method for cleaning

av lyskasterglass på motorkjøretøyer eller lignende, samt anordning for utførelse av fremgangsmåten. '"' ' of headlight glass on motor vehicles or the like, as well as devices for carrying out the method. '"' '

For rengjøring av glasset på lyskastere på kjøretøyer anvendes i dag samme prinsipp som Ved rengjøring, av kjøretøyets vinduer, og, For cleaning the glass on headlights on vehicles, the same principle is used today as when cleaning the vehicle's windows, and

da spesielt frontvinduet, og hvorved rengjøringen av lyskasterglasset skjer ved en kombinasjon av spyling med kald spylevæske fra dyser og pussing med en lyktepusser. Ved lave' temperaturer, d.v.s. temperaturer under 0°C,. hender det ikke så sjelden at lyktepusser-bladene er fastfrosne til lyskasterglassene. Igangsettes motoren som driver lyktepusseren vil motoren kunne brennes opp. og ødelegges. then especially the front window, and whereby the cleaning of the headlight glass takes place by a combination of flushing with cold washing liquid from nozzles and polishing with a lamp cleaner. At low temperatures, i.e. temperatures below 0°C,. it is not so rare that the lamp cleaner blades are frozen to the headlight lenses. If the engine that drives the headlight cleaner is started, the engine could be burnt up. and destroyed.

Ved vanlig bruk av lyskasterne vil dessuten lyskasterglassene bli-oppvarmet til relativt høye temperaturer åv lyskasternes glødelamper. Denne oppvarming av lyskasterglassene er spesielt markant ved anvendelse av halogenglødelamper. Når på denne måte oppvarmede lyskasterglass spyles med kald spylevæske utsettes selve glasset for en -sjokklignende temperaturveksling; som ikke sjelden resulterer i slike spenninger i glasset at det sprekker. Ved den konvensjonelle rengjøringsmetode .er en effektiv rengjøring også avhengig av at selve pusserbladene er' intakt, og det kreves derfor stadig ettersyn og : / utveksling av defekte pusserblad. Dette medfører i sin tur ekstra-omkostninger for bileieren. In normal use of the headlamps, the headlamp glasses will also be heated to relatively high temperatures by the headlamps' incandescent lamps. This heating of the headlight lenses is particularly marked when halogen incandescent lamps are used. When headlight glass heated in this way is flushed with cold flushing fluid, the glass itself is exposed to a -shock-like temperature change; which not infrequently results in such stresses in the glass that it cracks. With the conventional cleaning method, effective cleaning also depends on the sanding blades themselves being intact, and therefore constant inspection and: / exchange of defective sanding blades is required. This in turn entails extra costs for the car owner.

Nærvacrende oppfinnelse vedrører en hy fremgangsmåte for rengjøring av lyskasterglass, fortrinnsvis-uten anvendelse av lyktepussere,og fremgangsmåten er. i hovedsakkarakterisert vedåt lyskasterglassene spyles og rengjøres med varm spylevæske, som under overtrykk strømmer . ut gjennom hensiktsmessig plasserte, og innstilte munnstykkeenheter. Ifølge en foretrukket ,'utføreisésform av fremgangsmåten pumpes spyle væsken fra en forrådsbeholder for spylevæske'til en oppvarmihgsan-ordning for den samme, hvorfra den oppvarmede spylevæske ledes 1 grenrør til spesielle munnstykkeenheter, som er slik plassert, fortrinnsvis på bilens fremre støtfangere, og.innstilt at det rettes en kraftig stråle av spylevæske mot lyskasterglasset. The present invention relates to a method for cleaning headlight glass, preferably without the use of lamp cleaners, and the method is. mainly characterized by the fact that the headlight lenses are flushed and cleaned with hot flushing fluid, which flows under positive pressure. out through appropriately placed and adjusted nozzle units. According to a preferred embodiment of the method, the washing liquid is pumped from a storage container for washing liquid to a heating system for the same, from which the heated washing liquid is led 1 branch pipe to special nozzle units, which are thus placed, preferably on the car's front bumpers, and. set so that a powerful jet of washer fluid is directed at the headlight glass.

Med fremgangsmåten ifølge nærværende oppfinnelse ér de -forannevnte ulemper ved de hittil kjente fremgangsmåter eliminert» Således er det ikke lenger nødvendig å anvende''lyskasterpussere, og oppvarmede lyskasterglass vil ikke. bli utsatt for de påkjenninger og kon-sekvenser som spyling med kald spylevæske' innebærer. With the method according to the present invention, the aforementioned disadvantages of the hitherto known methods are eliminated. Thus, it is no longer necessary to use headlight cleaners, and heated headlight glasses will not. be exposed to the stresses and consequences that flushing with cold flushing fluid entails.

Et ytterligere aspekt ved oppfinnelsen er en anordning for utførelse av fremgangsmåten. Anordningen består, av en pumpe som suger spylevæske fra en forrådsbeholder for spylevæské, og anordningen erkarakterisert vedat den består av kun den nevnte forrådsbeholder eller en ytterligere spylevæskebeholder på pumpens trykkside, hvor-, ved forrådsbeholderen henholdsvis den ytterligere spylevæskebehold-eren er anordnet for oppvarming av spylevæsken; grenrør som leder den oppvarmede spylevæsken til på grenrørenes ender anordnende '; spesielle munnstykker.. ' ^. A further aspect of the invention is a device for carrying out the method. The device consists of a pump that sucks washing liquid from a storage container for washing liquid, and the device is characterized by the fact that it consists of only the aforementioned storage container or an additional washing liquid container on the pressure side of the pump, where, at the storage container or the additional washing liquid container is arranged for heating the flushing fluid; branch pipes which lead the heated flushing liquid to the ends of the branch pipes providing '; special nozzles.. ' ^.

Ifølge en spesiell utførelsesform av anordningen ifølge oppfinnelsen er oppvarmingsbeholderen for spylevæske anordnet direkte i kontakt' med motorens grenrør for avgasser, ifølge en ytterligere spesiell utførelsesform utgjøres de nevnte munnstykker av en ny konstruksjon,. som nedenfor vil bli nærmere, forklart ved hjelp av tegninger.'. According to a special embodiment of the device according to the invention, the heating container for flushing fluid is arranged directly in contact with the engine's branch pipe for exhaust gases, according to a further special embodiment, the aforementioned nozzles are of a new construction. which will be explained in more detail below with the help of drawings.'.

Ved hjelp'av de" nevnte kuler kan hodet 22 og dermed væskestrålen gjennom munnstykkehullet 20 innstilles i ønsket posisjon ved at det kanfinne sted,en vrid- In fig. 3, the foot'10 as well as the head 22 are molded in plastic, preferably nylon, and connected through a thin-walled., tube 21, preferably metal tube as in each. end'.is "attached to balls 14, preferably metal balls. These balls 14 are driven down into the cylindrical openings 15 of the foot 10 and the head 12". As these openings 15 have a somewhat smaller diameter than the balls 14, the balls 14 force a seat 15' in the elastic plastic material. With the help of the aforementioned balls, the head 22 and thus the liquid jet through the nozzle hole 20 can be set in the desired position by a twisting

ning såvel horisontalt-som vertikalt i både foten og hodet.-. ning both horizontally and vertically in both the foot and the head.-.

Spylevæsken trykkes av pumpen via/slangehippelen 13 og det tynn-yeggede røret 21 gjennom hullet 26 i kameret.18 bakenfor munnstykke-enheten. Pumpen driver opp trykket i væsken- i kammeret; l8,, og herved presses stemplet 24r med sin tetningsstahg 24 tilbake,'hvorved også returfJæren 23 presses sammen. Tetningsstangén 24 frilegger derved . hullet 20 i spylemunnstykkets fremre del. Spylevæsken presses nå ut i spylemunns tykke ts fremre kammer 19 , g J eniiom kanalen 17.: Denne kanal munner ut i det fremre kammer, vinkelrett motvutsprutningshullet 20.'Ved at kanalen 17 munner ut tett inn til den.ene veggen i kammeret 19, bringes væsken ,1 rotasjon og antar herved en traktform når den kommer ut gjennom hullet 20. Ved å endre hullet 20 kan væskens trakt-' form økes eller minskes for' således å kunne tilpasses lyskastere av forskjellige dimensjoner. ■-' •■. '. The flushing liquid is pushed by the pump via the hose hinge 13 and the thin-eyed tube 21 through the hole 26 in the chamber 18 behind the nozzle unit. The pump drives up the pressure in the liquid - in the chamber; l8,, and thereby the piston 24r with its sealing rod 24 is pressed back, whereby the return spring 23 is also pressed together. The sealing rod 24 thereby exposes. the hole 20 in the front part of the spray nozzle. The flushing liquid is now forced out into the thick front chamber 19 of the flushing mouth, through the channel 17.: This channel opens into the front chamber, perpendicular to the splash hole 20. As the channel 17 opens close to the wall of the chamber 19, the liquid is brought into rotation and thereby assumes a funnel shape when it comes out through the hole 20. By changing the hole 20, the funnel shape of the liquid can be increased or decreased so that it can be adapted to headlights of different dimensions. ■-' •■. '.

Når pumpen etter avsluttet spyling stoppes,' synker, trykket i spylevæsken hvorved returfJæren 23 presser t^tnlngsstangen 24 tilbake i utgangsposisjonen og stangens fremre ende lukker hull.et 20. Kanalen 25 er en evakuéringskanal som muliggjØr evakuering henholdsvis innslipping av luft bakenfor stemplet 24' ved dennes åpnings-. henholdsvis returbevegelse. , ; 'v. : i - (' v. ;■•:'■•'. When the pump is stopped after flushing has finished, the pressure in the flushing liquid drops, whereby the return spring 23 pushes the control rod 24 back into the starting position and the front end of the rod closes the hole 20. The channel 25 is an evacuation channel which enables the evacuation or entry of air behind the piston 24' at its opening. respectively return movement. , ; 'v. : i - (' v. ;■•:'■•'.

Ved at lukking av spylesystemet skjer ved systemets'aller siste del, nemlig hullet 20, elimineres all risiko for. at systemet; skal fryse ved kald værtype. Denne risiko'skulle ellers foreligge da den ved kald værtype til spylevæsken, tilsatte frostvæsken/ såsom isopropyl-eller metylalkbhol, ved -oppvarmingen skulle dampe vekk og/det gjen-værende vannet fryse. Denne vent ilanordnin<g>en fungerer også, som . systemets sikkerhetsventil, da den ved en trykkøkning,.. som opp- , står hvis spylevæskens.temperatur av noen årsak skulle øke unormalt, åpner på samme måte,som om trykkøkningen skulle skje véd.pumpens \ innvirkning.. By closing the flushing system at the very last part of the system, namely the hole 20, all risk of that the system; should freeze in cold weather. This risk would otherwise exist when, in cold weather, the antifreeze added to the washer fluid/such as isopropyl or methyl alcohol would evaporate during heating and/the remaining water would freeze. This waiting device also works, as . the system's safety valve, since it opens in the same way as if the pressure increase were due to the pump's \ impact.

Det er åpenbart at-enkelte detaljer ved-munnstykket kan endres innen-for rammen av nærværende oppfinnelse. Spesielt kan nevnes at f.eks. returfJæren 23 og stemplet 24' kan, tenkes utbyttet mot henholdsvis en megnet og .en belg som er koplet, sammen.. It is obvious that certain details of the nozzle can be changed within the scope of the present invention. In particular, it can be mentioned that e.g. The return spring 23 and the piston 24' can be thought of as being replaced by a magnet and a bellows which are connected together.
