Abstract

The dishwasher consists of a housing (10) and a washing chamber (11). In a sectional plan view, the combined basket structure and door (17) are arranged to pivot about a vertical axis (26) located in the chamber (11), the door being carried by upper and lower pivot arms (25). In pivoting, the lateral edges of the door, and the maximum laterally projecting parts of the basket structure, keep within a circle of a particular radius (R) to keep clear of all parts of the stationary housing. The upper and lower edges of the door and door opening (18) diverge to permit it to swing clear in the opening direction. The door and basket assembly may be pivoted around to any angle to give maximum accessibility to all parts of the basket including both sides and the rear. The door may be rotated by 230 degrees from its closed position.

Description

10 15 20 25 30 35 454 839 detta läge blir ventilen lätt åtkomlig. Uppbyggnaden av venti- len är dessutom enkel och billig. 10 15 20 25 30 35 454 839 this position makes the valve easily accessible. The structure of the len is also simple and inexpensive.

Dessa och övriga för uppfinningen utmärkande detaljer och fördelar förklaras närmare med hänvisning till en på bifogade ritning som exempel visad utföringsform av grovdiskmaskin med separationsventil enligt uppfinningen.These and other details and features of the invention benefits are explained in more detail with reference to one of the attached drawing as an example shown embodiment of a dishwasher with separation valve according to the invention.

Pig. l är ett schematiskt axialsnitt genom en grovdiskmaskin enligt uppfinningen. fig. 2 är en detaljbild i förstorad skala av separationsventilen 1 ett nedre ändläge, och fig. 3 är samma snitt men visar separationsventilen i ett övre ändläge.Pig. 1 is a schematic axial section through a dishwasher according to the invention. Fig. 2 is a detail view on an enlarged scale of the separation valve 1 a lower end position, and Fig. 3 is same section but shows the separation valve in an upper end position.

Den vertikala behandlingskammaren 10 har en botten ll som lutar ned mot ett utlopp 12. vilket via en ledning 13 är förbundet med en cirkulationspumps 14 sugsida. Pumpen matar diskvätska via ledningar 15. 16 till i kammaren 10 anordnade munstycken 17 för sprutning av diskvätska mot diskgods i kammaren. Diskgodset uppbäres av korgar 18 i det visade exemplet eller av andra diskgodsbärare.The vertical treatment chamber 10 has a bottom 11 which slopes down towards an outlet 12. which is via a conduit 13 connected to a circulating pump 14 suction side. The pump feeds dishwashing liquid via lines 15. 16 to the chamber 10 arranged nozzles 17 for spraying dishwashing liquid against dishes in the chamber. The dishes are supported by baskets 18 as shown example or by other dishwasher carriers.

I diskvätskan är på känt sätt inblandad en förutbestämd mängd granuler som är tyngre än vätskan och kan sjunka ned för att samlas på bottnen ll under vissa förhållanden. Granulerna består lämpligen av plast på känt sätt.A predetermined amount is involved in the dishwashing liquid in a known manner granules that are heavier than the liquid and can sink to accumulate on the bottom ll under certain conditions. The granules preferably consists of plastic in a known manner.

Under en förutbestämd period av diskprogrammet skall den genom munstyckena utsprutade vätskan innehålla granuler för effektiv bearbetning och avlägsnande av smuts och avsättningar på diskgodset. medan under andra perioder skall vätska utan granuler sprutas ut mot diskgodset. För detta ändamål finns en separationsventil 20.During a predetermined period of the washing program, it shall pass through the nozzles sprayed liquid contain granules for effective processing and removal of dirt and deposits on the dishes. while in other periods liquid without granules are sprayed onto the dishes. For this purpose there is one separation valve 20.

Såsom framgår av fig. 2 och 3 består den som exempel visade separationsventilen 20 av en vertikal ventilring 21 som ligger koaxiellt ovanför utloppet 12 och som i ventilringens nedre ändläge enligt fig. 2 med sin nedre ände 22 tätar mot bottnen 11 vid ett parti 11A kring utloppet 12. _ ' 10 15 20 25 30 35 454 839 Vid den relativt låga ringens 21 övre ände är anordnat ett separationsorgan 23 i form av en perforerad silplât som är inrättad att under alla förhållanden avskilja granuler i vätskan son passerar genom separationsorganet för att i ventilringens läge enligt fig. 2 strömma vidare ned till utloppet 12.As can be seen from Figures 2 and 3, it consists of examples shown the separation valve 20 of a vertical valve ring 21 lying coaxially above the outlet 12 and as in the lower of the valve ring end position according to Fig. 2 with its lower end 22 sealing against the bottom 11 at a portion 11A around the outlet 12. 10 15 20 25 30 35 454 839 At the upper end of the relatively low ring 21 is arranged one separation means 23 in the form of a perforated screen plate which is set up to separate granules in all conditions in the liquid son passes through the separating means to i the position of the valve ring according to Fig. 2 flows further down to outlet 12.

Vid mitten av separationsorganet 23 är fäst en vertikalt rörlig stolpe 23A. vars vertikala rörelse manövreras med en e] visad anordning som samtidigt åstadkommer en vridrörelse av ventilringen 21 som uppbär separationsorganet 23. Med hjälp av denna stolpe kan ringen 21 med separationsorganet 23 sålunda förflyttas mellan sitt nedre ändläge i fig. 2 och sitt övre ändläge i fig. 3.Attached to the center of the separating member 23 is a vertical one movable post 23A. whose vertical movement is maneuvered with an e] shown device which simultaneously causes a rotational movement of the valve ring 21 which supports the separating means 23. By means of this post can thus ring 21 with the separating member 23 moved between its lower end position in Fig. 2 and its upper end position in Fig. 3.

Inuti ringen 21 är anordnad en relativt ringen stationär strypskiva 24 som uppbäres av ett antal stift 25 fästade vid insidan av utloppet 12. skivans strypkant 24A ligger på fri höjd ovanför en strypkant 21A hos ringen 21 när ringen befinner sig i sitt nedre ändläge enligt fig. 2. Hellan de båda kanterna 24A, 21A erhålles därvid en genomströnningsspalt 25 för av separationsorganet 23 renad vätska som strömmar vidare ned genom ringen till ut- loppet samt till pumpen 14.Arranged inside the ring 21 is a relatively stationary ring throttle plate 24 supported by a number of pins 25 attached to inside the outlet 12. the throttle edge 24A of the disc is at a free height above a throttle edge 21A of the ring 21 when the ring is in its lower end position according to Fig. 2. The two edges 24A, 21A are obtained thereby a through-gap gap 25 of the separating means 23 purified liquid which flows further down through the ring to the barrel and to the pump 14.

De av separationsorganet 23 stoppade granulerna sjunker därvid ned på sidan om ringen 21 och samlas pâ den lutande bottnen ll i utrymmet kring ringen 21 såsom visas i fig. 2.The granules stopped by the separating means 23 then sink down on the side of the ring 21 and accumulates on the inclined bottom ll in the space around the ring 21 as shown in Fig. 2.

För inblandning av granuler i vätskan till pumpen omställes ventilrlngen 21 till sitt övre ändläge enligt fig. 3. Kanterna 24A och 21A kommer därvid att befinna sig i ett läge relativt varandra som stryper flödet av vätska nedströms separations- organet 23. Istället är en spalt 27 öppnad mellan ringens nedre ände 22 och bottenpartiet 11A kring utloppet 12. Vätska och granuler kan därigenom strömma fritt ut genom spalten 27 och ned i utloppet sant vidare till pumpen. 454 839 Kammaren 10 har en áörr 28 som öppnas när dískkorgarna skall föras in i eller ut ur kammaren. När denna dörr är öppen och korgarna är uttagna har man fritt och bekvämt tillträde till separatíonsventilen 20 vid bottnen av kammaren för rengöring och annan service av ventilen.For mixing granules in the liquid to the pump is adjusted the valve ring 21 to its upper end position according to Fig. 3. The edges 24A and 21A will then be in a relative position which restrict the flow of liquid downstream of the separation the member 23. Instead, a gap 27 is opened between the ring lower end 22 and bottom portion 11A around outlet 12. Liquid and granules can thereby flow freely out through the gap 27 and down in the outlet true on to the pump. 454 839 The chamber 10 has a tube 28 which opens when the dish baskets are to be opened inserted into or out of the chamber. When this door is open and the baskets are taken out, you have free and convenient access to them the separation valve 20 at the bottom of the chamber for cleaning and other service of the valve.
