i DK 169291 B1in DK 169291 B1
Opfindelsen angår en dyse af den art, der er angivet i krav l's indledning.The invention relates to a nozzle of the kind set forth in the preamble of claim 1.
Sådanne dyser anvendes til rensning af og især fjernelse 5 af tilstopninger fra husholdningsafløb og lignende, hvor kraften fra de stråler af væske, i reglen vand, der strønrauner ud fra de forskellige stråleåbninger, udnyttes til at løsne og fjerne snavs, der hæfter til afløbskanalens vægge og forhindrer afløbsvandets strømning.Such nozzles are used for cleaning and, in particular, removing clogging of household drains and the like, where the force of the jets of liquid, as a rule, water flowing from the various jetting openings is utilized to loosen and remove debris adhering to the walls of the drains. and prevents drainage flow.
10 Når en sådan dyse, der er forbundet med enden på en højtryksvandslange, skubbes ned gennem et afløbsrør ved at skubbe slangen ind i afløbsåbningen, skal det fremadrettede bøjelige organ forhindre, at der opstår problemer, når dysen støder på en forhindring, såsom en skarp 15 rørdrejning eller endefladen på et rør i en samling, der vender i den modsatte retning. Dersom brugeren prøver at bevæge dysen forbi forhindringen ved at udøve mere kraft på slangen, ville resultatet ellers ofte være, at slangen bøjes i endeområdet med dysen pegende mere eller mindre på 20 tværs af afløbskanalens omgivende del, og yderligere skubning ville kun gøre sagen værre, idet dysen ville blive mere eller mindre fastkilet i afløbskanalen.10 When such a nozzle connected to the end of a high pressure water hose is pushed down through a drain pipe by pushing the hose into the drain opening, the forward flexible member should prevent problems when the nozzle encounters an obstacle such as a sharp one. 15 or the end face of a pipe in a joint facing in the opposite direction. If the user tries to move the nozzle past the obstacle by exerting more force on the hose, otherwise the result would often be that the hose bends in the end area with the nozzle pointing more or less across the surrounding portion of the drainage channel and further pushing would only make the case worse, the nozzle being more or less wedged in the drainage channel.
I US-A-3.195.548 er der foreslået en dyse, der gør det lettere at føre en sammenklappelig plastslange gennem et 25 afløbs- eller kloakrør med henblik på rengøring. Dette skrift omhandler således en dyse af den art, der er angivet i krav l's indledning, og ifølge skriftet omfatter dysen flere, nemlig mindst to, kugleformede elementer på række langs med den skrueviklede fjeder, hvis vindinger 30 ligger tæt sammen.US-A-3,195,548 has proposed a nozzle that facilitates passing a collapsible plastic hose through a 25 drain or sewer pipe for cleaning. Accordingly, this specification discloses a nozzle of the kind set forth in the preamble of claim 1, and according to the specification the nozzle comprises several, namely at least two, spherical elements in series along the helically wound spring, the windings 30 of which are close together.
I den således kendte dyse er der i samtlige kugleformede elementer, inklusive det forreste, udformet en gennemgående passage. Den væskestråle, der kommer ud af dysen, vil kun fortsætte usvækket gennem det forreste kugle- DK 169291 B1 2 formede element i de sjældne tilfælde, hvor hele rækken af kugleformede elementer flugter nøjagtigt med dyseåbningen i dysekroppen. Desuden vil de tætliggende fjeder-5 vindinger i mellemrummene mellem de kugleformede elementer i sig selv svække væskestrålen og sprede denne på mange steder, hvorfor der kun kan opnås en relativt svag rense-effekt, selv om væsken tilføres under højt tryk.In the nozzle thus known, a continuous passage is formed in all spherical elements, including the front. The fluid jet coming out of the nozzle will only continue unimpeded through the front ball-shaped element in the rare cases where the entire row of spherical elements exactly aligns with the nozzle opening in the nozzle body. In addition, the adjacent spring windings in the spaces between the spherical elements per se will weaken the liquid jet and disperse it in many places, so that only a relatively weak cleaning effect can be achieved even if the liquid is supplied under high pressure.
ydermere bevirker den fremadrettede dyseåbning, at strålen 10 herfra er tilbøjelig til at skubbe dysen bagud gennem afløbsrøret.further, the forward nozzle aperture causes the jet 10 from here to tend to push the nozzle backward through the drain pipe.
Selv når strålen rammer de kugleformede elementer eller fjedervindingerne foran dyseåbningen, vil den frembragte fremadrettede kraft på grund af strålens spredning være 15 forholdsvis svag, og er for lille til at kunne modvirke den bagudrettede reaktionskraft, der frembringes ved dyseåbningen.Even when the jet strikes the spherical elements or the spring windings in front of the nozzle opening, the forward force produced by the scattering of the jet will be relatively weak and is too small to be able to counteract the reverse reaction force produced at the nozzle opening.
Det er opfindelsens formål at anvise en forbedret dyse af den art, der kendes fra US-A-3.195.548, der har en endnu 20 større evne til at finde vej gennem afløbsrør, og som tilvejebringer en forbedret rensevirkning, og dette formål opnås med en dyse, som tillige udviser de træk, der er angivet i krav l's kendetegnende del.It is an object of the invention to provide an improved nozzle of the kind known from US-A-3,195,548 which has an even greater ability to find its way through drainage pipes and which provides an improved purification effect and this object is achieved with a nozzle which also exhibits the features specified in the characterizing portion of claim 1.
Anvendelsen af radialt udadrettede dyseåbninger er i sig 25 selv kendt fra EP-A-0.015.649. Dette skrift beskriver et apparat til rensning af rørledninger ved hjælp af en børste, der drives af en vandturbine. Snavs eller glødeskal, der hænger fast på et rørs indervæg, løsnes eller afskrælles af den hurtigt roterende børste, og 30 skylles derpå bort af den trykvæske, der har været brugt til at drive vandturbinen.The use of radially outward nozzle openings is itself known from EP-A-0.015,649. This document describes an apparatus for cleaning pipelines by means of a brush operated by a water turbine. Dirt or glow peel attached to the inner wall of a pipe is loosened or peeled off by the rapidly rotating brush, and then peeled away by the pressure fluid used to drive the water turbine.
Desuden kendes fra GB-A-2.047.377 en dyse med seks skråt fremad- og udadrettede dyseåbninger samt en central, DK 169291 B1 3 fremadrettet dyseåbning, idet der i sidstnævnte er indsat den ene ende af en skruefjeder med en længde af størrelsesordenen 40 cm, hvis modsatte ende bærer et langstrakt, 5 nærmest ellipsoideformet hoved, som ligeledes består af skrueviklet metaltråd. Vindingerne i den lange skruefjeder ligger tæt sammen, mens vindingerne i hovedet er anbragt med store mellemrum. Under brugen føres hele værktøjet med hovedet forrest ind i det rum, der skal renses, mens 10 vandet strømmer ud, dels i form af skråt fremad- og udadrettede stråler fra de førstnævnte seks åbninger, dels som en strøm gennem den lange skruefjeder og hovedet, idet hovedet og skruefjederen tilvejebringer den mekaniske renseeffekt, mens strålerne og strømmen tilvejebringer den 15 hydrauliske renseeffekt samt udskylningen af det løsnede materiale. Også med denne dyse kan en bagudrettet reaktionskraft forventes, navnlig fra de skråt udad- og fremadrettede dyseåbninger.Also known from GB-A-2,047,377 is a nozzle with six oblique forward and outward nozzle openings and a central, nozzle opening, with one end of a screw spring having a length of the order of 40 cm being inserted. , the opposite end of which carries an elongated, 5 ellipsoid-shaped head, which also consists of screw-wound metal wire. The windings in the long screw spring are close together, while the windings in the head are arranged at large intervals. During use, the entire tool is fed head-first into the space to be cleaned while the water flows out, partly in the form of oblique forward and outward jets from the first six openings, and partly as a current through the long screw spring and head, the head and screw spring providing the mechanical cleaning effect, while the jets and the flow providing the hydraulic cleaning effect and the flushing of the loosened material. Also with this nozzle, a reverse reaction force can be expected, especially from the inclined outward and forward nozzle openings.
Under brugen af dysen ifølge opfindelsen vil de bagud-20 rettede stråler frembringe en reaktionskraft, der modvirker reaktionskraften fra den aksiale, fremadrettede stråle. Desuden vil strålen fra den fremadrettede dyseåbning enten ramme det massive knop- eller kugleformede element og frembringe en fremadrettet kraft mod dette, 25 eller den vil blive udsprøjtet med stor slagkraft mod rørets væg gennem mellemrummene mellem de åbne fjedervindinger.During use of the nozzle according to the invention, the backward jets will produce a reaction force which counteracts the reaction force of the axial forward jet. In addition, the jet from the forward nozzle aperture will either hit the solid knob or spherical member and produce a forward force against it, or it will be extruded with great impact against the wall of the pipe through the spaces between the open spring windings.
Når en sådan dyse nærmer sig en forhindring i en afløbskanal af den ovenfor antydede art, vil det knop-30 eller kugleformede element vige til side, når det rammer forhindringen. På denne måde vil også det langstrakte bøjelige organ blive afbøjet til siden, hvorefter det virker som et styr, der skånsomt leder selve dysen forbi forhindringen, medens det også bøjer slangen en smule i 35 den udstrækning, der er nødvendig til at tillade dysen at passere forhindringen.When such a nozzle approaches an obstacle in a drainage channel of the above type, the knob-30 or spherical element will fall apart as it hits the obstacle. In this way, the elongated flexible member will also be deflected to the side, after which it acts as a guide, gently guiding the nozzle itself past the obstacle, while also flexing the hose slightly to the extent necessary to allow the nozzle to pass. the obstacle.

Hensigtsmæssige udførelsesformer for dysen ifølge opfindelsen, hvis virkninger - ud over, hvad der er er selvindlysende - er forklaret i den efterfølgende specielle 5 del af nærværende beskrivelse, er angivet i krav 2-8.Suitable embodiments of the nozzle according to the invention, the effects of which - in addition to what is self-evident - are explained in the following special part of this specification are set out in claims 2-8.
Opfindelsen skal i det følgende forklares nærmere under henvisning til det på tegningen viste udførelseseksempel på en spuledyse ifølge opfindelsen, idet fig. 1 viser dysen fastgjort til enden på en højtryks-10 slange, set fra siden og delvis i snit, og fig. 2 er et tværsnit efter linien II-II i fig. 1.The invention will be explained in more detail below with reference to the exemplary embodiment of a flushing nozzle according to the invention, with fig. 1 shows the nozzle attached to the end of a high-pressure hose, side view and partially in section, and FIG. 2 is a cross section along line II-II of FIG. First
Den på tegningen viste spuledyse 10 omfatter en dysekrop 11 med en langsgående kanal 12, der forbinder det indre af et rør eller en slange 13 med et antal stråleåbninger, 15 nemlig en aksial stråleåbning 14, der er rettet i den fremadgående bevægelsesretning 15 af dysen 10, når denne anvendes til rensning og/eller spuling af det indre af en ikke vist afløbskanal, såsom afløbsrøret fra en køkkenvask, et badekar eller lignende, såvel som et antal 20 - i det viste eksempel 3 - radial/aksiale eller skråtrettede stråleåbninger 16, som til dels er rettet modsat den nævnte fremadgående bevægelsesretning 15.The flush nozzle 10 shown in the drawing comprises a nozzle body 11 having a longitudinal channel 12 connecting the interior of a pipe or hose 13 with a plurality of jet openings 15, namely an axial jet opening 14 directed in the forward direction of movement 15 of the nozzle 10. when used for cleaning and / or rinsing the interior of a drainage channel (not shown), such as the drainage pipe from a kitchen sink, bathtub or the like, as well as a number of 20 radial / axial or oblique beam openings 16, as shown in Example 3, which is partially directed opposite said forward movement direction 15.
Dysekroppen 11 er fastgjort til røret eller slangen 13 ved hjælp af en rørring 17 eller hvilke som helst andre dertil 25 egnede organer, der ikke udgør en del af nærværende opfindelse, hvorfor de ikke skal beskrives nærmere i nærværende beskrivelse.The nozzle body 11 is attached to the tube or hose 13 by means of a tube ring 17 or any other means suitable for it 25 which do not form part of the present invention, and therefore are not to be described in more detail in this specification.
Omkring den forreste ende af dysekroppen 11, der indeholder den aksiale stråleåbning 14, er der fastgjort 30 den inderste ende af en skruefjeder 18, hvis ydre ende er fastgjort til et knop- eller kugleformet element 19 med en afrundet overflade 20, som i hovedsagen vender i den fremadgående retning 15. Den modsatte ende eller side af det knop- eller kugleformede element 19 er udformet med en DK 169291 Bl 5 konisk overflade 21, der konvergerer modsat den fremadgående retning 15. I en ikke vist udførelsesform er overfladen 21 formet som en hel kegle, der peger hen imod 5 dyseknoppen 11.Around the front end of the nozzle body 11 containing the axial beam opening 14, 30 is secured to the inner end of a coil spring 18, the outer end of which is secured to a knob or spherical member 19 with a rounded surface 20 which faces generally in the forward direction 15. The opposite end or side of the knob or spherical element 19 is formed with a conical surface 21 which converges opposite to the forward direction 15. In an embodiment not shown, the surface 21 is formed as a whole cone pointing towards the 5 nozzle knob 11.
Som det kan ses af fig. 1, har fjederen 18 åbne vindinger, med undtagelse af enderne, hvor tætte vindinger 22 griber fast omkring propdele 23 og 24 på henholdsvis dyseknoppen 11 og det knop- eller kugleformede element 19, således at 10 de på denne måde holder elementet 19 fast i forhold til fjederen 18 og sidstnævnte fast i forhold til dyseknoppen 11.As can be seen from FIG. 1, the spring 18 has open turns, with the exception of the ends, where tight turns 22 grip around the plug parts 23 and 24 on the nozzle knob 11 and the knob or spherical member 19, respectively, so that in this way they hold the member 19 in proportion to the spring 18 and the latter fixed relative to the nozzle knob 11.
Under brugen indføres spuledysen 10 sammen med den forreste ende af slangen 13 i den åbne ende af den 15 afløbskanal, der skal renses eller befries for en tilstopning, hvorefter slangen 13 forbindes med en kilde for højtryksvæske, såsom vand med eller uden passende tilsætninger. HøjtrykvæskekiIden kan med fordel være et højtryksrenseapparat af den art, der leverer væske ved 20 betydeligt højere tryk end vandværkstryk. Stråler af højtryksvæske vil derfor strømme ud fra både den aksiale stråleåbning 14 og de radial/aksiale stråleåbninger 16, og disse stråler vil delvis opløse og/eller løsne snavs, der findes i afløbskanalen, og delvis danne en væskestrøm, der 25 fører det således opløste og/eller løsnede snavs bort fra området omkring spuledysen 10. Yderligere vil de bagudrettede komposanter af de stråler, der strømmer ud af de skrå stråleåbninger 16, skabe en reaktionskraft, der modvirker reaktionskraften fra den fra den aksiale 30 stråleåbning 14 udstrømmende stråle, således at det bliver lettere for brugeren at holde spuledysen 10 i den ikke viste afløbskanal og bevæge den inden i denne i den fremadgående bevægelsesretning 15.During use, the flush nozzle 10 is inserted with the front end of the hose 13 into the open end of the 15 drain channel to be cleaned or freed of a clogging, after which the hose 13 is connected to a source of high pressure liquid such as water with or without appropriate additives. The high pressure fluid range can advantageously be a high pressure cleaning apparatus of the kind that delivers fluid at 20 considerably higher pressures than waterworks pressure. Therefore, high-pressure fluid jets will flow from both the axial jet orifice 14 and the radial / axial jet orifices 16, and these jets will partially dissolve and / or loosen debris found in the drainage channel, and partially form a fluid stream that conducts the thus dissolved. and / or loosened debris away from the area around the nozzle 10. Further, the rearward components of the jets flowing out of the oblique jet openings 16 will create a reaction force counteracting the reaction force of the jet exiting from the axial jet jet 14, such that it becomes easier for the user to hold the flush nozzle 10 in the drain channel not shown and move it within it in the forward movement direction 15.
Når spuledysen 10 under sin fremadgående bevægelse i 35 retningen 15 inden i en afløbskanal støder på en DK 169291 B1 6 forhindring, såsom en rørbøjning eller endefladen på et rør i en sammenføjning, vil det knop- eller kugleformede element 19 søge at undgå forhindringen ved at bevæge sig 5 sideværts - dsv.vinkelret på den fremadgående retning 15 -idet det tager den forreste ende af fjederen 18 med sig. Ved yderligere fremadgående bevægelse vil fjederen 18, som nu er bøjet til siden bort fra forhindringen, virke som et styr, der styrer dysekroppen 11 forbi forhindringen, idet 10 en fremadvendende affasning 25 på selve dysekroppen 11 gør det muligt for denne at passere forhindringen uden at hænge fast i denne. En bagudvendende affasning 26 på dysekroppen 11 virker på en lignende måde, når spuledysen 10 bevæges i den modsatte retning.When the coil nozzle 10 during its forward movement in the direction 15 within a drain channel encounters an obstruction, such as a pipe bend or the end surface of a pipe in a joint, the knob or spherical element 19 will seek to avoid the obstruction by move 5 sideways - perpendicular to the forward direction 15 - taking with it the front end of the spring 18. With further forward movement, the spring 18, which is now bent sideways away from the obstacle, will act as a guide guiding the nozzle body 11 past the obstacle, 10 a forward bevel 25 on the nozzle body 11 itself allowing it to pass the obstacle without hang on to this one. A rear-facing bevel 26 on the nozzle body 11 acts in a similar manner as the coil nozzle 10 moves in the opposite direction.
15 Ved stationære tilstande vil den koniske overflade 21 på den bagudvendende ende på det knop- eller kugleformede element 19 afbøje den fra den aksiale stråleåbning 14 udstrømmende væskestråle på sådanne tidspunkter, hvor elementet 19 befinder sig i en passende stilling i 20 forhold til dysekroppen 11, idet den afbøjede stråle i så fald tjener til at rense området omkring elementet 19. Dersom den koniske overflade på ikke vist måde er formet som en hel kegle, vil den fra den aksiale stråleåbning 14 udstrømmende væske ramme den koniske overflade, når det 25 knop- eller kugleformede element 19 befinder sig i eller tæt ved den viste stilling, således at strålen vil blive fordelt i området omkring elementet 19. Når elementet 19 imidlertid bevæges gennem en ikke ubetydelig afstand fra den viste koaksiale stilling, så vil væskestrålen fra den 30 aksiale stråleåbning 14 strømme ud mellem de åbne vindinger i fjederen 18 - eller til dels ramme nogle af disse - og bidrage til rensevirkningen ved at ramme en væg noget længere fremad i afløbskanalen, eller snavs, der blokerer passagen til den nævnte væg. Dette gælder 35 selvsagt også for det viste tilfælde, hvor overfladen 21 er en keglestuboverflade.In stationary conditions, the tapered surface 21 on the rearward end of the knob or spherical member 19 deflects the fluid jet flowing from the axial beam opening 14 at such times when the member 19 is in a suitable position relative to the nozzle body 11. in which case the deflected beam serves to clean the area around the element 19. If the conical surface is not formed in the manner shown as a whole cone, the liquid flowing from the axial beam opening 14 will hit the conical surface when it reaches the knob. or spherical member 19 is in or close to the position shown, so that the jet will be distributed in the area around the member 19. However, when the member 19 is moved through a not insignificant distance from the shown coaxial position, the liquid jet from the axial beam aperture will 14 flow out between the open windings in the spring 18 - or partially hit some of these - and contribute to the cleaning effect by hitting a wall slightly further ahead in the drainage channel, or dirt blocking the passage to said wall. This of course also applies to the case shown where the surface 21 is a cone stub surface.

Normalt vil imidlertid den fra den aksiale stråleåbning 14 udstrømmende væskestråle fremkalde en "dynamisk1' tilstand, hvor elementet 19 sammen med fjederen 18 danner en 5 hydro-mekanisk oscillator, sådan at forstå, at elementet 19 svinger hurtigt frem og tilbage i tværretningen, idet den hertil fornødne energi leveres af væskestrålen i samvirke med den bagudvendende del af elementet 19. Helt præcist, hvorledes dette foregår, vides ikke, men det 10 drejer sig formentlig om en virkning svarende til den, der opstår, når man fra siden fører en bøjelig kvist eller lignende ind i kraftig, tynd vandstråle. Uanset hvorledes fænomenet skal forklares, bevirker svingningen af elementet 19 i tværretningen, at dette formelig virker som 15 en hammer, der banker snavset løs fra de vægge, den måtte komme i berøring med. Det således løsnede snavs vil derpå blive skyllet bort af væsken.Normally, however, the fluid jet flowing from the axial jet opening 14 will produce a "dynamic" state, with the element 19 together with the spring 18 forming a hydro-mechanical oscillator, to understand that the element 19 swings rapidly back and forth in the transverse direction, the energy required for this is supplied by the liquid jet in collaboration with the rearward part of the element 19. It is not known exactly how this is done, but it is probably an effect similar to that which occurs when a flexible twig is carried from the side Irrespective of how the phenomenon is to be explained, the oscillation of the element 19 in the transverse direction causes this to formally act as a hammer knocking the dirt loose from the walls it may come into contact with. dirt will then be washed away by the liquid.
det viste og beskrevne udførelseseksempel består det agrregat, der omfatter det langstrakte bøjelige organ 18 20 og det knop- eller kugleformede element 19, af en skruefjeder med et dertil fastgjort element. Det er imidlertid indenfor opfindelsens rammer muligt at udforme dette aggregat på andre måder eller at erstatte det med et organ, der er udformet i ét stykke. Den langstrakte 25 bøjelige del kunne således udgøres af et metalrør, der er gjort bøjeligt ved opslidsning og strækning på samme måde som såkaldt strækmetal, en gummislange med huller eller slidser, en gummistang med langsgående noter i flugt med et antal aksiale stråleåbninger i dyselegemet, eller et 30 antal gummistænger anbragt omkring en åbning. Det knopeller kugleformede element kunne være udformet i ét stykke med den bøjelige del. Dersom den bøjelige del er en gummistang, kunne det knop- eller kugleformede element være udformet i ét stykke med stangen og yderligere 35 omfatte en permanent fastgjort, stiv metalhætte, så slidstyrken bliver forbedret.In the exemplary embodiment shown and described, the aggregate comprising the elongated flexible member 18 20 and the knob or spherical member 19 consists of a coil spring with a member attached thereto. However, it is possible within the scope of the invention to design this assembly in other ways or to replace it with a one-piece member. The elongated flexible member could thus be constituted by a metal tube which is made flexible by slitting and stretching in the same way as so-called stretch metal, a rubber tube with holes or slots, a rubber rod with longitudinal grooves in flight with a plurality of axial jet openings in the nozzle body, or a plurality of rubber bars disposed about an opening. The knob or spherical member could be integrally formed with the flexible member. If the flexible member is a rubber rod, the knob or spherical member could be integrally formed with the rod and further comprise a permanently attached rigid metal cap to improve wear resistance.
