Description

456 10 15 20 25 30 35 40 636 Z. är säkrad med ett skyddsgaller (DE Offenlegungsschrift 25 08 730) och rengöringsmedel användes, vilka med avseende pa sin upplösningshastighet inte är optimerade eller har samman- packats genom en längre lagring i påbörjade förpackningar. Ett icke fullständigt under diekförloppet löst rengöringsmedel leder till ett sämre rengöringsresultat och paverkar verkan av det sura spolglansmedlet. 456 10 15 20 25 30 35 40 636 Z. is secured with a protective grille (DE Offenlegungsschrift 25 08 730) and cleaning agents are used which, with regard to their dissolution rate, are not optimized or have been packed by a longer storage in started packaging. An incompletely dissolved detergent during the dike process leads to a poorer cleaning result and affects the effect of the acidic rinse aid.

För uppfinningen ligger till grund uppgiften att utforma en anordning av det inledningsvis nämnda slaget så att den skyddar pumparna från grovdelar, men ända later smutsdelar, som inte kan leda till en tílltäppning eller skadande av pumparna kan passera, och att nackdelarna pa grund av pa utloppstragbottnen avlagrande, outnyttjat rengöringsmedel förhindras.The object of the invention is to design a device of the kind mentioned in the introduction so that it protects the pumps from coarse parts, but still leaves dirty parts which can not lead to a clogging or damage to the pumps can pass, and that the disadvantages due to the outlet trough bottom depositing, unused detergent is prevented.

Denna uppgift löses enligt uppfinningen genom de i kännetecknande delen av kravet 1 angivna särdragen.This object is solved according to the invention by the features stated in the characterizing part of claim 1.

Utformningar av uppfinningen är angivna i kraven 2 till Enligt uppfinningen uppfyller grovsilen uppgiften att urskilja grova smutsdelar från den cirkulerande spolvätskan och halla dem borta fran inloppet till cirkulations- och tömningspumpen, sa att deras pumphjul varken kan blockeras eller förstöras. Å andra sidan kan mjuka matrester, t.ex. större mjölkhinnor, grönsaksrester eller liknande passera grovsilen genom dess stora genomsläpp i grovsilsöverdelen och pumpas bort av tömningspumpen. Silöppningarna i grovsilsunder- delen är i deras maskvidd så avpassade att grovsilen bildar en uppfangningsbehallare för fasta grovsmutsdelar, vilka är tömningsbara genom urtagande av grovsilen ur maskinen. Slut- ligen bildar grovsilsunderdelen även en uppfàngningsbehallare speciellt för grovgranulärt rengöringsmedel. Rengöringemedels- granulatet hålls kvar av grovsilen och kan inte direkt komma in i tömningspumpens insugningsstutsar. I grovsilen utsattes rengöringsmedlet för den av cirkulationspumpen astadkomna vâtskeetrömningen, sa att det bríngas i lösning.Designs of the invention are set out in claims 2 to According to the invention, the coarse screen fulfills the task of distinguishing coarse dirt parts from the circulating flushing liquid and keeping them away from the inlet to the circulation and discharge pump, so that their impellers can neither be blocked nor destroyed. On the other hand, soft food residues, e.g. larger milk membranes, vegetable residues or the like pass the coarse strainer through its large passage in the coarse strainer top and are pumped away by the emptying pump. The screen openings in the coarse screen part are adapted in their mesh size so that the coarse screen forms a collecting container for solid coarse dirt parts, which can be emptied by removing the coarse screen from the machine. Finally, the coarse strainer lower part also forms a catch container especially for coarse granular detergent. The detergent granules are retained by the coarse strainer and cannot enter directly into the suction nozzles of the emptying pump. In the coarse screen, the cleaning agent is exposed to the liquid flow effected by the circulation pump, so that it is brought into solution.

Uppfinningen förklaras närmare med hjälp av ett pa ritningen visat utföringsexempel. Där visar fig, 1 en schema- tisk vy av den undre delen av en spolbehallsre i en diskmaskin med en anordning enligt uppfinningen, och fig, 2 ett utförande av en grovsil i anordningen enligt fig. 1. 10 15 20 25 30 35 456 636 ß I bottentràget 1 hos spolbehàllaren i en diskmaskin är ett utloppstràg 2 anordnat, vilket uppvisar en anslutninga- stuts 3 för en cirkulationspump liksom vid utloppstràgbottnen en anslutningsstuts 4 för en tömningspump. Över utloppstràget befinner sig en finsil 5, som trattformigt övergår i en fin- silcylinder 6, som skjuter in i utloppstraget och begränsar en tömningskanal 7 till tömningspumpens anslutningsstuts 4. I tömningskanalen 7 är en grovsil 8 anordnad.The invention is explained in more detail with the aid of an exemplary embodiment shown in the drawing. There, Fig. 1 shows a schematic view of the lower part of a rinsing hopper in a dishwasher with a device according to the invention, and Fig. 2 shows an embodiment of a coarse strainer in the device according to Fig. 1. 456 636 ß In the bottom trough 1 of the rinsing tank in a dishwasher a discharge trough 2 is arranged, which has a connecting spout 3 for a circulation pump as well as at the outlet trough bottom a connecting spout 4 for an emptying pump. Above the outlet trough is a fine sieve 5, which funnels in a funnel-shaped manner into a fine sieve cylinder 6, which projects into the outlet trough and delimits an emptying channel 7 to the connecting spout 4 of the emptying pump. A coarse screen 8 is arranged in the emptying channel 7.

Vid det visade utföringsexemplet uppvisar överdelen 9 till grovsilen 8 flera över varandra anordnade horisontellt förlöpande slitsar 10, avlånga hal eller liknande, vilkas slitsbredd är sa avpassad, att i grovsilen flytande mjuka matrester, såsom t.ex. mjölkhinnor, salladsrsster, spenat eller liknande, kan passera slitsarna 10 och pumpas bort av tömningspumpen. Tunga, hårda smutsrester, såsom ben, glas- skärvor eller liknande avsättas i grovsilens 8 underdel 11 och avskärmas fràn vätskeströmmen till pumparna. , Grovsilsunderdelen 11 kan enligt utföringsexemplet uppvisa en sluten mantel 12 och en silbotten 13 eller en silmantel och en sluten botten eller en silbotten och en silmantel. I varje utförande är maskvidden hos silöppningarna 14 i grovsilsunderdslen sà avpassade, att de grova, ännu inte upplösta rengöringsmedelskornen, när de efter rengörings- medelstillförseln spolas in i íilteranordningen, hålls kvar i grovsileunderdelen fram till upplösning. Eftersom grovsilen är utsatt för den av cirkulationspumpen astadkomna strömningen, accelererss upplösningsförloppet av rsngöríngsmedlet. Mask- vidden hos silöppningarna 14 i grovsilsunderdelsn 11 uppgar till ungefär 1 mm.In the exemplary embodiment shown, the upper part 9 of the coarse screen 8 has several horizontally extending slots 10, elongate slides or the like arranged one above the other, the slot width of which is so adapted that soft food residues floating in the coarse screen, such as e.g. Milk membranes, lettuce, spinach or the like, can pass through the slots 10 and be pumped away by the drain pump. Heavy, hard dirt residues, such as bones, shards of glass or the like, are deposited in the lower part 11 of the coarse screen 8 and are shielded from the liquid flow to the pumps. According to the exemplary embodiment, the coarse screen lower part 11 can have a closed jacket 12 and a screen bottom 13 or a screen jacket and a closed bottom or a screen bottom and a screen jacket. In each embodiment, the mesh width of the screen openings 14 in the coarse screen subdivision is so adapted that the coarse, not yet dissolved detergent granules, when they are flushed into the filter device after the detergent supply, are retained in the coarse screen subassembly until dissolution. Since the coarse screen is exposed to the flow produced by the circulation pump, the dissolution process of the cleaning agent is accelerated. The mesh width of the sieve openings 14 in the coarse sieve lower part 11 amounts to approximately 1 mm.

Grovsilen 8 kan bilda en urtagbar insats mot finsilen 5 eller kan vid plastmaterialsilar med finsilen vara sammanbyggd till en del. Vid tilltäppta silöppningar 14 i grovsilsunder- delen 11 kan tunga, grova beståndsdelar ända avsättas i grov- silen, medan det till grovsilen spelade rengöríngsmedlet tillsammans med den uppdämda spolvätskan strömmar bort via slitsarna 10 i grovsilsöverdelen 9.The coarse screen 8 can form a removable insert against the fine screen 5 or can be partially assembled with plastic screen screens with plastic screen screens. In the case of clogged screen openings 14 in the coarse screen lower part 11, heavy, coarse components can still be deposited in the coarse screen, while the cleaning agent spilled into the coarse screen together with the trapped rinsing liquid flows away via the slots 10 in the heavy screen top 9.
