Description
J) Lafi 40 447 354 2 avstängningsvcntil 3 samt en tryckdosa 4 och en flottör 5. Till- förselventilen Z och avstängningsventilen 3 bildar en konstruk- tionsenhet med en tíllförselstuts 6 och en utloppsstuts 7 för vatten. J) La fi 40 447 354 2 shut-off valve 3 and a pressure box 4 and a float 5. The supply valve Z and the shut-off valve 3 form a construction unit with a supply spout 6 and an outlet spout 7 for water.
Avstängningsventilen 3 utgör en modifiering av den magnet- ventil som försüljs av Siemens AG under scriebeteckningen ZHB, varvid hos denna ventil elektromagnetsystemet är ersatt av en permanentmagnet 8. En sådan ventil arbetar enligt principen för hydraulisk hjälpavlastning, dvs. vattenledningsnätets tryck under- stöds genom en av magnotens ankare öppnad eller tíllsluten ut- jämningsborrning i ventilmembranet (ej visat) för dettas öppnings- eller tillslutningsförlopp. Tryckdosan 4 uppvisar ett hus 9 med en i sidled utåtriktad anslutningsstuts 10, vilken över en slang står i förbindelse med en luftkammare (ej visat) utsatt för vätske- trycket i hushållsapparatens arbetsbehållare. Innanför tryckdosans hus 9 befinner sig permanentmagneten 8, vars magnetfält står i verksam förbindelse med avstängningsventilens ej synliga ankare genom ett vid avstängningsventilens 3 ventilhus 11 angränsande, tunnväggigt gavelavsnítt 12 hos tryckdosans hus. Med permanent- magneten 8 är tryckdosans 4 gummielastiska membran 13 förbundet.The shut-off valve 3 constitutes a modification of the solenoid valve sold by Siemens AG under the write designation ZHB, in which case the solenoid system is replaced by a permanent magnet 8. Such a valve operates according to the principle of hydraulic auxiliary relief, ie. the pressure of the water supply network is supported by an equalization bore in the valve diaphragm (not shown) opened or closed by the magnot's anchor (not shown) for its opening or closing process. The pressure box 4 has a housing 9 with a laterally outwardly directed connecting spout 10, which over a hose communicates with an air chamber (not shown) exposed to the liquid pressure in the working container of the household appliance. Inside the housing 9 of the pressure box is the permanent magnet 8, the magnetic field of which is in effective communication with the invisible anchor of the shut-off valve through a thin-walled end section 12 of the pressure box housing adjacent to the valve housing 11 of the shut-off valve 3. The rubber-elastic membrane 13 of the pressure box 4 is connected to the permanent magnet 8.
Vid dess kant fasthâlls membranet lusttätt genom ett lock 14 vilket tillsluter tryckdosans hus 9 vid dess från ventilen vända sida. Vid membranets 13 från magneten vända sida ingriper likaså en med detta förbunden tryckplatta 15. Vid tryckplattan 15 är ut- bildad en tapp 16 vilken sträcker sig genom tryckdosans 4 lock 14 för inkoppling med flottören 5.At its edge, the diaphragm is held tightly by a lid 14 which closes the housing 9 of the pressure box at its side facing away from the valve. At the side of the diaphragm 13 facing away from the magnet, a pressure plate 15 connected thereto also engages. At the pressure plate 15 a pin 16 is formed which extends through the lid 14 of the pressure box 4 for connection to the float 5.
På tryckplattans 15 tapp 16 är styrd en tryckfjäder 17, vilken med dess ena ände stöder mot tryckplattan, och med dess andra ände angriper mot ändytan hos en i tryckdosans 4 lock 14 längdinställ- bart styrd gängbussníng 18. Härigenom kan genom motsvarande för- spänning av tryckfjädern 17 avstängningsventilens 3 omkopplings- punkt inställas vid en bestämd vätskenivå i hushàllsapparatens arbetsbehållare.A compression spring 17 is controlled on the pin 16 of the pressure plate 15, which with its one end abuts against the pressure plate, and with its other end engages against the end surface of a longitudinally controlled threaded bushing 18 in the pressure box 4 lid 14. This can by corresponding pretensioning of the pressure point 17 of the shut-off valve 3 of the shut-off valve is set at a certain liquid level in the working container of the household appliance.
Tappen 16 har vid dess från membranet 13 vända fria ände ett smalare parti 19, vilket vid tappens ände övergår i en flüns 20¿ Det smalare partiet 19 omgríps av en vid änden gaffelformig häv- arm 21 hos en tvåarmad hävstång 22, vars andra hävarm 23 står i förbindelse med flottören 5. Denna flottör 5 är tillordnad ett i hushållsapparaten anordnat uppfângningstråg Z4 för läckvatten.The pin 16 has at its free end facing away from the diaphragm 13 a narrower portion 19, which at the end of the pin merges into a flange 20. The narrower portion 19 is gripped by a fork-shaped lever 21 at the end of a two-armed lever 22, the second lever 23 of which is connected to the float 5. This float 5 is assigned to a catchment tray Z4 for leaking water arranged in the household appliance.
Förbindningen mellan tryckdosen 4 och flottören 5 med avstäng- lll lv UK dl in -Hl s 447 334 ningsventilen 5 åstadkommes genom en konstruktionsdel 25, vilken är Fäst vid ventilhnset ll. Helen 25 har i mitten en öppning 26 för det tunnväggiga gavelväggpurtiet IZ hes tryckdosans hus 9.The connection between the pressure dose 4 and the float 5 with the shut-off valve ll UK dl in -Hl s 447 334 ning valve 5 is effected through a construction part 25, which is attached to the valve head 11. Helen 25 has in the middle an opening 26 for the thin-walled gable wall door IZ hes pressure box housing 9.
Utvündigt uppvisar konstruktionsdelen 5 på inbördes avstånd anord- nade armar 27, med vilka den runda tryckdosan 4 lägesfixerat omgrips vid omkretsen. Dessutom har konstruktionsdelen 25 lager- hockar 28 för flottörens 5 hävstäng 22.Externally, the construction part 5 has mutually spaced arms 27, with which the round pressure box 4 is fixedly positioned at the circumference. In addition, the construction part 25 has bearing hooks 28 for the lever 22 of the float 5.
Sükerhetsanordningen arbetar på följande sätt: Vid störíngsfri drift hos hushâllsapparaten är avstängníngs- ventilen 3 öppnad. Vattentíllförseln i apparatens arbetsbehållare erhalls genom öppning av den från apparatens styrning manövrerade tillförselventilen Z. Vid uppnående av driftsnivån i arbetshehållaren stängs tillförse1ven1iIen Z genom en driftsnivåvnkt. Om nlvåvakten ej fungerar eller om tíllförselventilen 2 ej stängs, uppnår vätske- ståndet l arbetsbehållaren den så kallade säkerhetsniván, vid vilken det indirekt under vätskans tryck stående membranet 13 hos tryck- dosan 4 har lyft pcrmanentmagneten så långt från dess ankare i ventilhuset ll, att avstängníngsventilen 3 spärrar vidaretillförsel av vatten.The safety device works as follows: During trouble-free operation of the household appliance, the shut-off valve 3 is opened. The water supply to the working container of the appliance is obtained by opening the supply valve Z operated by the control of the appliance. When the operating level in the working container is reached, the supply valve Z is closed by an operating level switch. If the pressure monitor does not work or if the supply valve 2 is not closed, the liquid level in the working container reaches the so-called safety level, at which the membrane 13 of the pressure box 4, which is indirectly under pressure, has lifted the permanent magnet so far from its anchor in the valve housing the shut-off valve 3 blocks the supply of water.
Vid tömning av apparatens arbetsbehållare sänks trycket på memhranet l3, så att permanentmagneten 8 återvänder till dess utgangsläge, under det att ankaret i avstängningsventilen 3 drager och följaktligen överför ventilen till dess öppna läge.When emptying the working container of the apparatus, the pressure on the membrane 13 is lowered, so that the permanent magnet 8 returns to its initial position, while the armature in the shut-off valve 3 pulls and consequently transfers the valve to its open position.
Under denna slagrörelse hos membranet bortkopplas flottören 5 frän tryckdosan 4, eftersom härvid tappens 16 avsmalnande parti förmår röra sig fritt i den vid änden gaffelformiga hävarmen 21.During this percussion movement of the diaphragm, the float 5 is disconnected from the pressure box 4, since in this case the tapered portion of the pin 16 is able to move freely in the fork-shaped lever 21 at the end.
Vid uppträdande av läckage i arbetsbehållaren, hos ventilerna Z, 3 eller vid någon annan vattenförande konstruktionsdel hos hushållsapparaten, samlas läckvattnet i det på bottnen anordnade tråget 24. Den härígenom upplyfta flottören 5 ingriper med häv- armen Zl på flänsen 20 hos tryckplattans 15 kapp 16 och åstadkommer över kopplingen med membranet 13 även upplyftníng av permanent- magneten 8 från dess ankare i avstängningsventílen 3. Redan vid en ringa mängd läckvatten í tråget 24 förskjuts permanentmagneten 8 så mycket, att avstängningsventílen 3 stängs och förhindrar all ytterligare vattentillförsel i apparaten. Även vid felfunktíon hos tryckdosan 4 åstadkommer det ut ur arhetshehållaren överströmmande vattnet en stängning av avstäng- ningsventilen 3 genom upplyftning av flotrören 5. Följaktligen utesluts en vattenskada vid hushàllsapparatens uppställníngsplfltfi-In the event of a leak in the working container, at the valves Z, 3 or at any other water-carrying component of the household appliance, the leaking water collects in the trough 24 arranged on the bottom. The float 5 thereby raised engages with the lever Z1 on the flange 20 of the pressure plate casing 16. and also causes the permanent magnet 8 to be lifted over the coupling with the diaphragm 13 from its anchor in the shut-off valve 3. Even with a small amount of leaking water in the trough 24, the permanent magnet 8 is displaced so much that the shut-off valve 3 closes and prevents any further water supply in the apparatus. Even in the event of a malfunction of the pressure box 4, the water overflowing from the unit holder causes a closing of the shut-off valve 3 by lifting the float pipes 5. Consequently, a water damage is excluded at the set-up plate of the household appliance.
