Description
457 932 10 15 20 25 30 35 :fin 2 vid tryckdosans membran pà den ena sidan uppbär en permanent- magnet och pa den andra sidan tillsammans med åtminstone en flottör omedelbart är kopplat pa så sätt; att flottören vid förekomst av läckvatten för undan ventilmembranet i ett vid bottensidan förekommande uppfángningskärl hos apparaten. Vat- tentilloppet i hushallsapparatens spolbehallare sker genom oppnande av den av apparatstyrningen kopplade, för maskinen speciella, elektromagnetiskt styrda tilloppsventilen. Vid upp- naende av driftnivàn i spolbehallarsn astadkommer en drift- nivavakt slutning av den elektromagnetiska tilloppsventilen. vid strejkande nivavakt eller da den elektromagnetiska till- loppsventilen inte sluter uppnar vätskestandet i spolbehal- laren den s.k. säkerhetsnivan, vid vilken det indirekt under vätskans tryck stående membranet hos tryckdosan lyfter en permanentmagnet så långt från dess ankare i ventilhuset, att den permanentmagnetpaverkbars spärrventilen pa maskinsidan spärrar det fortsatta tilloppet av vatten. Vid denna anordning star tilloppsslangen ständigt under vattenledningsnätets tryck, da spärrkranen är öppnad. 457 932 10 15 20 25 30 35: fin 2 at the diaphragm of the pressure box on one side carries a permanent magnet and on the other side together with at least one float is immediately connected in this way; that the float, in the presence of leaking water, removes the valve diaphragm in a collecting vessel of the apparatus located at the bottom side. The water inlet into the flushing tank of the household appliance takes place by opening the electromagnetically controlled inlet valve connected to the appliance by the appliance control. When the operating level in the flushing tank is reached, an operating level monitor closes the solenoid inlet valve. during a strike level guard or when the solenoid inlet valve does not close, the liquid level in the flushing tank reaches the so-called the safety level at which the diaphragm under pressure of the liquid of the pressure box lifts a permanent magnet so far from its anchor in the valve housing that the permanent magnet actuator shut-off valve on the machine side blocks the continued supply of water. In this device, the inlet hose is constantly under the pressure of the water supply network, when the shut-off valve is opened.
Uppfinningen har till uppgift att astadkomma en säker- hetsanordning för vattenförande hushållsapparater av det in- ledningsvis nämnda slaget, enkelt uppbyggd, vilken anordning är speciellt vilken anordning ocksa övertar nivafyllningen samt -övervakningen, vilken anordning bildar ett verksamt skydd mot elangbrott och vilken anordning haller tillopps- slangen trycklös utanför ifyllningsprogramstegen.The object of the invention is to provide a safety device for water-carrying household appliances of the type mentioned in the introduction, simply constructed, which device is in particular which device also takes over the level filling and monitoring, which device forms an effective protection against electrical breakage and which device keeps access - the hose without pressure outside the filling program steps.
Denna uppgift löses genom de i patentkravet 1 angivna särdragen. Denna lösning utmärkas av en speicellt enkel uppbyggnad, eftersom den pa epärrkranen befintliga, av hushàllsapparatens programkopplingsverk styrda, elektroma- kaniska tilloppsventilen styr spolbehàllarens nivàpafyllning och med undantag för de i hushallsapparatens program föregivna vattenifyllningsstegen spärrar vattentílloppet direkt vid spärrkranen och därigenom skyddar tilloppsslangen mot slang- brott. Den i serie med den programstyrda, elektromagnetiska tilloppsventilen likaledes pa vattenlednin befintliga, gsnätets spärrkran mekaniskt pàverkbara spärrventilen arbetar ström- löet via en tryckdosa och är därför ocksa verksam vid ström- bortfsll eller bortkopplad hushallsapparat. med tryckkammaren hos det för maskinen speci Den via en ledning ellt anordnade 10 15 20 25 30 35 40, 457 932 3 nivaregleringskärlet förbundna tryckdosan hos spärrventilen träder i funktion vid uppnaende av eäkerhetsnivan i maekinbe- hállaren och bringar spärrventilen till slutningsläget. Efter- som tilloppsalagen är trycklös vid sluten tilloppsventil lik- som vid sluten spärrventil hos tilloppeslangen uteslutas i det närmaste en sprängning av tilloppsslangen.This object is solved by the features stated in claim 1. This solution is characterized by a particularly simple construction, since the existing electromechanical inlet valve, controlled by the household appliance's program coupler, controls the level filling of the flush tank and, with the exception of the water filling steps provided in the household appliance program, blocks the water supply . In a series with the program-controlled, electromagnetic inlet valve, which is also present on the water main, the mechanical shut-off valve of the gas network operates the current via a pressure box and is therefore also effective in the event of a power failure or disconnected household appliance. with the pressure chamber of the pressure box of the shut-off valve connected via a line or via a line or 15 15 40 25 30 35 40, 457 932 3, the pressure box connected to the shut-off valve comes into operation when the safety level in the machine container is reached and brings the shut-off valve to the closed position. Since the inlet hose is depressurized at the closed inlet valve as well as at the closed shut-off valve of the inlet hose, an explosion of the inlet hose is virtually excluded.
Enligt en fördelaktig utformning är huehàllsapparaten försedd med ett vid bottensidan anordnat läckvattenuppfang- ningskärl samt en tillhörande kopplingsanordning. En fullstän- dig övervakning av tilloppsslangen uppnae genom ett från tilloppsventilepärrventilen utgàr en tilloppselangen omhöl- jande läckvattenelang, som fritt mynnar i läckvattenuppfang- ningskärlet, samt att en fran en flottör i läckvattenuppfàng- ningskärlet paverkbar kopplingeanordning är förbunden med den elektriska styrledningen för tilloppsventilens magnetepole. Om tilleppaslangen under ett ifyllningsprogramsteg skulle vara otät, net av läckvattenslangen och ledee in i läckvattenuppfang- sa upptagee det från tilloppsslangen utpasserande vatt- ningekärlet, där kopplingsanordningen omedelbart utlöser elut- ningen av tilloppeventilen vid spärrkranen. Inte heller en otäthet inuti maskinen eller bortfall av den säkerhetsnivan övervakande mekaniska spärrventilen skulle kunna leda till en översvämning hos uppetällningsrummet. En ytterligare säkerhet erhålles slutligen genom att den elektromagnetiska tilloppe- ventilen är sluten i strömlöst tillstànd.According to an advantageous design, the cap holding device is provided with a leakage water collecting vessel arranged at the bottom side and an associated coupling device. A complete monitoring of the inlet hose achieved by a leakage water hose enclosing the inlet valve shut-off valve from the inlet valve shut-off valve, which opens freely into the leakage water collecting vessel, and that one of the floats in the leakage water collection cup control vessel is connected to the solenoid valve. If the clogging hose should be leaking during a filling program step, the net of the leaking water hose and the lead into the leaking water trap will receive the watering vessel exiting the inlet hose, where the coupling device immediately triggers the electric discharge of the inlet valve at the shut-off valve. Nor could a leak inside the machine or failure of the safety level monitoring mechanical shut-off valve lead to a flood in the counting room. An additional safety is finally obtained by closing the solenoid solenoid valve in the de-energized state.
En ytterligare fördelaktig utformning av uppfinningen är kännetecknad i patentkravet 3.A further advantageous embodiment of the invention is characterized in claim 3.
Uppfinningen beskrivas nedan med hjälp av ett pà rit- ningen askadliggjort utföringsexempel.The invention is described below with the aid of an exemplary embodiment embodied in the drawing.
