Description

i 146614in 146614

Den foreliggende opfindelse angår en opvaskemaskine til brug i husholdninger og af den i kravets indledning angivne art.The present invention relates to a dishwasher for domestic use and of the kind specified in the preamble of the claim.

Indenfor denne teknik forekommer der allerede løsninger på problemet med at udforme en lejring til en skyllearm direkte 5 på opvaskekurven og en ledning for skyllevæsken til den pågældende arm. Med en sådan løsning elimineres nødvendigheden af et centralt i opvaskerummet opragende trykrør til at lede væsken til en øverst på røret anordnet skyllearm. Opvaskekurven må dog ved disse kendte løsninger anbringes i en be-10 stemt arbejdsstilling. Ved meget varierende størrelse for opvaskegodset opstår det ønskemål at flytte kurven i højderetningen i opvaskerummet, således at man kan opnå en optimal udnyttelse af dette. For at man kan opnå en bedre udnyttelse af opvaskerummet kræves det, at også skyllearmen flyttes med 15 kurven, og at dens tilslutning til skyllesystemet er reguler bar efter den for kurven valgte højde.Within this technique, solutions to the problem of designing a bearing for a rinse arm directly 5 on the dishwashing basket and a line for the rinse fluid for that arm already exist. With such a solution, the necessity of a central pressure tube projecting in the washroom is eliminated to direct the liquid to a flush arm arranged at the top of the tube. However, in these known solutions, the washing basket must be placed in a determined working position. At very varying sizes for the dishwasher, it is desirable to move the basket in the height direction in the dishwasher so that it can be optimally utilized. In order to make better use of the washing room, it is also necessary that the rinsing arm is moved with the basket and that its connection to the rinsing system is adjustable according to the height chosen for the basket.

Fra tysk offentliggørelsesskrift nr. 2.355.271 kendes et skyl-lesystem med rørtilslutninger til forskellige kurvhøjder. Ifølge denne teknik udnyttes på det ene rør et muffelignende stykke, 20 der trådes over det andet rør. Når muffen fjernes fra stigrøret, er rørenderne åbne, og væske kan sprøjte ud gennem stigrøret, da dette ikke har nogen ventil der lukker, når muffen trækkes bort.German publication specification No. 2,355,271 discloses a flushing system with pipe connections for various basket heights. According to this technique, a sleeve-like piece 20 is threaded on one pipe which is threaded over the other pipe. When the sleeve is removed from the riser, the pipe ends are open and liquid can spray out through the riser as this has no valve that closes when the sleeve is pulled away.

Den foreliggende opfindelse anviser en løsning på problemet 25 med at tilslutte en skyllearm til et trykrør med en sådan in dividuel indstilling af armen i højderetningen, at opvaskerummet kan udnyttes optimalt ved varierende størrelse på opvaskegodset ved at den indledningsvist omtalte opvaskemaskine er ejendommelig ved det i den kendetegnende del af kra-30 vet anførte. Herved sikres, at begge ventiler lukkes, når endestykket trækkes bort fra stigrøret. Dette indebærer, at væske ikke kan strømme ud af stigrøret, der således er helt lukket. Dette giver mulighed for at drive maskinen med ekstra højt tryk i den nedre skyllearm. Såfremt man tager over- 2 146014 kurven vask, kan man således få en ekstra stor opvaskevirkning i underkurven. Skyllearmens indstillingsområde i højderetningen kan være udformet i trin eller trinløst, men bestemmes af en koblingsanordning på et trykrør ved opvaskerummets ene 5 væg. Koblingsanordningen har en løsbar forbindelse mellem trykrøret og en ledning til skyllearmen og holder forbindelsen tæt, når skyllearmen er i en arbejdsstilling på et af flere valgbare niveauer i opvaskerummet.The present invention provides a solution to the problem 25 of connecting a flushing arm to a pressure tube with such an individual adjustment of the arm in the height direction that the washroom can be optimally utilized at varying sizes of the dishwashing property by the initially mentioned dishwasher characterizing part of the requirement stated. This ensures that both valves are closed when the end piece is pulled away from the riser. This means that liquid cannot flow out of the riser, which is thus completely closed. This allows the machine to operate at extra high pressure in the lower rinse arm. Thus, if you take the basket over, you can have an extra large washing effect in the sub-basket. The height-setting setting of the flush arm may be stepwise or infinitely designed, but is determined by a coupling device on a pressure tube at one wall of the washroom. The coupling device has a detachable connection between the pressure pipe and a cord to the flushing arm and holds the connection tight when the flushing arm is in a working position at one of several selectable levels in the washing room.

Et udførelseseksempel på en opvaskemaskine ifølge opfindelsen beskrives neden for under henvisning til tegningen, hvor fig. 1 viser et lodret snit gennem skyllevandssystemet i en opvaskemaskine ifølge opfindelsen, og fig. 2 viser et lodret snit gennem en kobling i skyllevandssystemet, 15 i opvaskemaskinen ifølge fig. 1 indgår en cirkulationskreds for skyllevæske, der pumpes i et stigrør 10, der er forgrenet til to skyllearme 11, 12, som er anbragt i et opvaskerum 13 med en øvre og en nedre opvaskekurv 14, 15, der kan trækkes ud gennem en åbning i maskinens forside, der har en 20 låge 16. Den øvre ende af stigrøret har et par énvejsventiler 17, 18 anbragt på forskellige niveauer og (i det viste eksempel i fig. 2) er udformet som et par ventiltallerkener 19 der indefra af fjedre 20 er presset mod ventilhuller 21 i stigrøret. Den øvre kurv 14 har på undersiden en lejring 25 22 for skyllearmen 11, hvilken lejring har en gennemføring af en ledning 23 udstrakt bagud langs kurvens underside.An exemplary embodiment of a dishwasher according to the invention is described below with reference to the drawing, in which fig. 1 shows a vertical section through the rinsing system of a dishwasher according to the invention, and FIG. 2 shows a vertical section through a coupling in the rinsing system, 15 in the dishwasher according to FIG. 1, a flushing liquid circulation circuit is pumped into a riser 10, which is branched into two rinsing arms 11, 12 which are arranged in a washroom 13 with an upper and a lower wash basket 14, 15, which can be pulled out through an opening in the front of the machine having a gate 20. The upper end of the riser has a pair of one-way valves 17, 18 arranged at various levels and (in the example shown in Fig. 2) is formed as a pair of valve plates 19 which from the inside of springs 20 are pressed against valve holes 21 in the riser. The upper basket 14 has on the underside a bearing 25 22 for the rinsing arm 11, which bearing has a lead 23 extending rearward along the underside of the basket.

Ledningen står således i forbindelse med skyllearmen via lejringen på en sådan måde, at armen kan svinge frit, medens ledningen holdes stille. Den bagerste ende 24 af ledningen 30 er konisk og har på siderne indløbsåbninger 25. Når enden føres ind i et af ventilhullerne 21, tætner den koniske delThe cord thus communicates with the flushing arm via the bearing in such a way that the arm can swing freely while keeping the cord still. The rear end 24 of conduit 30 is tapered and has inlet openings 25 on its sides. When the end is inserted into one of the valve holes 21, the tapered portion seals
